The utility model has the advantages of favorable sealing performance and long service life and is suitable for industries such as environment protection, metallurgy, chemical industry, food, cement, building materials and the like.
Description
Technical field:
The utility model belongs to the technical field of valve machine manufacture, is specifically related to a kind of revolving plow reclaimer.
Background technology:
Revolving plow reclaimer is a kind of industries such as environmental protection, metallurgy, chemical industry, grain, cement, building materials that are widely used in, dry powdery material in the feed bin of top or small particles material be transported in next equipment continuously, equably go, be the specialized equipment of powdery or granular material discharging, feed and metering, batching.Because along with the development of micro-computer technology, every profession and trade constantly increases the real-time feed demand of powdery or granular material, requires feeder to combine with frequency conversion, speed regulation device, becomes real-time feeder apparatus; And, require to have good abrasion resistance because feeder uses frequently; In view of the needs of environmental protection, require valve to have excellent sealing performance, to guarantee the dependable service of feeding system.But just known to the contriver, present feeder integral body is not sealed, and material is leaked outside and causes valve not turn round normally; And existing feeder wears no resistance, the damage parts of contact medium is serious, service life short.
Summary of the invention:
The purpose of this utility model is exactly in order to remedy above deficiency, a kind of can in feeding system, frequently use that provides, and resistance to abrasion is good, the revolving plow reclaimer of long service life.
The utility model is to adopt following technical scheme to realize: described revolving plow reclaimer, it is characterized in that being provided with a cylinder valve (9), upper and lower side at valve body (9) respectively is provided with a back-up ring (6), back-up ring respectively is provided with an O type circle (8) up and down, be provided with multi-disc impeller (7) up and down between the back-up ring, on valve body (9) line of centers, by back-up ring (6) and impeller (7) valve rod (13) is set, be provided with filler (5) between valve rod (13) and the valve body (9), packing gland (4) is arranged in the lower end rear support (3) of valve rod (13) and valve body (9), be provided with rear bearing (2) between valve rod (13) lower end and the rear support (3), between the upper end of valve body (9) and valve rod (13), filler (10) is set, packing gland (11) is arranged on before the upper end of valve rod (13) and valve body (9) in the bearing (14), be provided with front bearing (12) between valve rod (13) upper end and the preceding bearing (14), at big blade and vanelets therebetween one deck flexible sealing strip (1) of impeller (7).Adopt the rotor of a plurality of blades, the material of top feed bin falls by deadweight and is filled in the interlobate space, and material draws off with the lower mouth that is rotated in of rotor.Space between rotor blade is a uniformity, and rotor speed both can be constant speed, can be speed change also, the more important thing is the development along with micro-computer technology, the ideal scheme that is combined into real-time feed of revolving plow reclaimer and frequency conversion, speed regulation device; In order to satisfy every profession and trade the real-time feed demand of powdery or granular material is constantly increased, use case type rotor to have better air locking, make with special high-abrasive material the end of rotor blade, can guarantee that blade tip and shell inwall have the good service life that can improve valve greatly that contacts, and adjusting vane end easily after the wearing and tearing; Bearings at both ends and impeller are designed to the external isolation structure, can prevent that superfine powder from contacting with bearing, makes valve opening and closing more flexible.
It is good that revolving plow reclaimer of the present utility model has closure, opens and closes flexibly, has wide range of applications, and the advantage of long service life has improved the in-use performance of like product greatly.
Description of drawings:
Accompanying drawing is the revolving plow reclaimer constructional drawing
Among the figure: 1, sealing band, 2, rear bearing, 3, rear support, 4, packing gland, 5, filler, 6, back-up ring, 7, impeller, 8, O type circle, 9, valve body, 10, filler, 11, packing gland, 12, front bearing, 13, valve rod, 14, preceding bearing.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment, revolving plow reclaimer comprises sealing band 1, rear bearing 2, rear support 3, packing gland 4, filler 5, back-up ring 6, impeller 7, O type circle 8, valve body 9, filler 10, packing gland 11, front bearing 12, valve rod 13, preceding bearing 14 as shown in drawings.Impeller 7 is made with valve body 9 and is used fully enclosed structure, add edge O type circle on a back-up ring and the back-up ring at the impeller two ends, O type circle and valve seal, so just guarantee the sealing of impeller and valve body, this hermetically-sealed construction can effectively prevent to contain the air of granular material or coal gas and leak outside and cause environmental pollution and equipment to be cavitated and damage.Add a plurality of fillers 10 at valve rod 13 places and guarantee that side seal is good, material is leaked outside cause the bearing grinding and cause valve not turn round normally.At big blade and vanelets therebetween one deck flexible sealing strip 1 of impeller 7, material is the wear resistant composite gel band, and it is one gentle one firm making impeller and contacting of valve body, and the wearing and tearing of valve body 9 inwalls are reduced greatly, has solved vane rotor and the valve body 9 serious problem that rubs.The front bearing 12 and the rear bearing 2 at two ends are isolated certain distance with impeller 7, and bearing is made outlet structure, can prevent that superfine powder from contacting with bearing, makes valve opening and closing more flexible.
