The belt filter press applies pressure to the material mainly comprises two modes of pressing and local rolling. The belt pressing is to spread solid-liquid mixture between the superposed sections of two tensioned annular filter belts, and when two layers of filter belts for clamping materials bypass multi-stage compression rollers with different diameters, the outer layer filter belt wound on the compression rollers generates pressure on the materials between the belts, so that the liquid components are discharged through the filter belts. The belt pressure strength depends on the tension of the belt and the diameter of the passing press roll. The higher the tension is, the higher the pressure of the outer layer belt wound on the compression roller on the material is; when the tension is fixed, the smaller the diameter of the compression roller is, the higher the pressure of the outer layer belt on the material is.
In order to further improve the pressure, when two layers of filter belts pass through the gaps of a plurality of pairs of parallel rollers, the rollers roll materials between the belts, and additional roller pressure is generated on the basis of belt pressure.
But because of the limitation of the tensile stability of the filter belt meshes, the strength of the ring joint and the strength of the high-pressure section small-diameter press roll, the belt pressure generated by the belt tension alone is generally not higher than 0.5 MPa. When parallel rollers are used for generating roller pressure, the pressure application time is short, and the material is easily jammed at the wedge-shaped entering side. In addition, on the belt filter press with several stages of press rolls and several pairs of press rolls, in the whole filter pressing operation, the material can only be pressed for several times (each stage of press rolls and press rolls is 2-3 s) for several seconds in a short time and with low pulsation and strength, and the dewatering effect is poor.

Referring to fig. 4 and 5, the width of the chain belt body is matched with the length of the rotary drum 2, the chain belt body is composed of a plurality of chain links 44 connected end to end, each chain link 44 comprises a bearing plate 441 and lug plates 442 fixedly connected to two sides of the bearing plate 441, an outer lug 443 is formed at one end of each lug plate 442, an inner lug 444 staggered with the outer lug 443 is formed at the other end of each lug plate 442, a notch 445 is formed at one end of each lug plate 442, which is opposite to the outer lug 443, and when the outer lug 443 of the adjacent chain link 44 is inserted into the notch 445, the inner lug 444 is attached to the outer lug 443, so that good connection is achieved. The inner hanging lug 444 and the outer hanging lug 443 of the adjacent chain links 44 are hinged through the positioning shaft 446, the positioning shaft 446 is rotatably connected with the roller 447, and when the material dragged by the chain belt body moves along the extrusion channel, the roller 447 can roll on the arc-shaped pressing plate 3 to reduce the friction force between the chain belt body and the arc-shaped pressing plate 3 so as to convey the material.
Referring to fig. 2 and 5, the pressure bearing plate 441 and the arc-shaped pressure plate 3 are provided with water permeable holes for accelerating drainage and preventing filtrate from accumulating. A water receiving tank 7 is fixed at a position right below the arc-shaped pressing plate 3 on the rack 1, the water receiving tank 7 can collect filtrate which flows down through the annular chain belt 4 and flows down through the rotary drum 2, a liquid discharge port 71 is arranged at the bottom of the water receiving tank 7, and the liquid discharge port 71 extends out of one side of the rack 1.
An elastic water absorption cushion block 8 is fixed on one side, abutted against the outer peripheral surface of the rotary drum 2, of the bearing plate 441 of each chain link 44, the elastic water absorption cushion block 8 is formed by processing foamed rubber and has certain elasticity, water permeability and water absorbability, and one side, facing the rotary drum 2, of the elastic water absorption cushion block 8 is coated with water permeable filter cloth 9 for intercepting fine particles. It should be noted here that when the material dragged by the chain belt body moves in the extrusion channel, the filtrate will respectively flow into the water receiving tank 7 through the annular chain belt 4 and the rotary drum 2, the elastic water absorption cushion block 8 will deform and shrink under the influence of the extrusion force, and at this time, the elastic water absorption cushion block 8 only has the function of water permeation and hardly absorbs water; when the chain belt body drags the materials to be separated from the rotary drum 2, the elastic water absorption cushion block 8 recovers deformation, and the elastic water absorption cushion block 8 can absorb the filtered free water which is not discharged in time, so that liquid resorption is avoided, and the dehydration effect of the materials is ensured; simultaneously, because elasticity cushion 8 that absorbs water can resume deformation when the chain belt body drags the material and separates with rotary drum 2, consequently, elasticity cushion 8 that absorbs water still has the effect of resilience loosening the soil, avoids the mud cake to adhere on the chain belt body surface.
In order to further improve the soil loosening effect, a plurality of grooves can be formed in the surface of the elastic water absorption cushion block 8, so that a plurality of small gaps are formed between the elastic water absorption cushion block 8 and the filter cloth 9 in a natural state, and the loosening degree is improved.
The implementation principle is as follows: after the material got into the wedge 6 of extrusion passageway feed end by feeding hopper 11, along with the removal of rotary drum 2 rotation and chain belt body get into between rotary drum 2 global and the chain belt body and remove along the extrusion passageway, the in-process of removal, because the clearance of extrusion passageway narrows gradually, consequently, the material can be compressed gradually, at this moment, liquid component in the material can see through respectively in chain link 44 and the filter cloth 9 on the rotary drum 2 flow to the water receiving tank 7, when the material of chain belt body traction and rotary drum 2 separate, elasticity suction pad 8 loosens the material that adheres on the chain belt body, the material after loosening is emptyd to discharge in slag notch 12 at the extreme position of conveying.
The material in the application is subjected to double squeezing of the annular chain belt 4, the rotary drum 2 and the arc-shaped pressing plate 3 applying pressure to the annular chain belt 4 during dehydration, so that the dehydration effect is greatly improved; the structural design of full-width matching between the rotary drum 2 and the annular chain belt 4 can ensure the structural strength and rigidity when high squeezing force is applied; continuous and stable squeezing power can be ensured by arranging the low-pressure cylinder 35 and the high-pressure cylinder 36 to adjust the clearance of the squeezing channel in a segmented manner; by arranging the elastic water absorption cushion block 8, the filtered free water which is not discharged in time can be absorbed, and the liquid is prevented from being sucked back; simultaneously, the elastic water absorption cushion block 8 can also loosen the material by restoring the deformation when the chain belt body drags the material to be separated from the rotary drum 2, so that the material is prevented from being adhered to the chain belt body.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
