The invention relates to the production of building materials, namely, lines for the manufacture of Limer concrete products.

The purpose of the invention is to expand technological capabilities and improve product quality by changing the binder composition.

FIG. Figure 1 shows a structural diagram of a line for the manufacture of polymer concrete products; in fig. 2 is a plan for separating a molding of a line of polymer concrete products.

The line for the manufacture of polymer concrete products contains the first receiving hopper 1, feeder 2. first feeding hopper 3, first bucket elevator 4, second feeding hopper 5, dryer 6, third feeding hopper 7, second receiving hopper 8, second bucket elevator 9, node 10 Fractionation hopper 11, continuous metering devices 12, first conveyor belt 13. third receiving hopper 14, third bucket elevator 15, filler mixer 16, fourth feed hopper 17, second conveyor belt 18, fourth receiving hopper 19 poly mixer merbeton, fifth receiving hopper 20, fourth bucket elevator 21, fifth feed hopper 22, ball mill 23, polymer concrete mixer 24, accelerator capacity 25, hardener capacity 26, binder reactor 27, pipelines 28-30, surface-active capacity 31 substances (surfactants). 32 and 33 synthetic binder capacities, pipelines 34-36, mechanically driven roller table 37, vibrating tables 38 and 39, polymerization chamber loader 40, polymerization chamber 41, chamber polymerization unloader 42, post 43 forms, post 44 cleaning and lubrication forms, post 45 the direction of the forms on the molding and post 46 fill forms.

Lini works as follows.

The mineral filler is poured into the first receiving bin 1, from where the feeder 2 is fed continuously to the first feed bin 3 and the first bucket elevator 4 is directed through the second feed bin 5 to the dryer 6.

The obtained dry mineral filler is guided through the third feed bin 7 and the second feed bin 8 by the second bucket elevator 9 in unit 10 of the taper fraction. A vibrating screen was used as the fractionation unit 10.

The fractionated mineral filler is directed to the fractions separately in the hopper 11. Each hopper 11 has volume-controlled dispensers 12 of continuous action.

According to the program, the individual fractions of mineral fillers installed on the control panel are metered in the required amount to a continuously operating

a horizontal first conveyor belt 13, from where the mineral fillers are directed to the third receiving hopper 14, and then to the third elevator 15 to the filler mixer 16,

For grinding the dry mineral filler is fed to the fifth receiving hopper 20 by the fourth elevator 21 through the fifth feed hopper 22 8 ball mill 23.

From the ball mill 23, the ground mineral filler flows in a continuous stream into the mixer 16 of dry fillers, where it is mixed with other mineral fillers.

fractions within 8-10 min. The use of a mill to obtain a dispersed fraction (2.4-23 m2 / g) of mineral fillers allows processing with a powder surfactant simultaneously with grinding,

The introduction of dispersed fillers treated with surfactants ultimately reduces the amount of binder in the polymer-concrete mixture.

The dry mixture of mineral fillers from the mixer 16 is directed through the fourth feed bin T7 to the inclined

the second belt conveyor 18 into the fourth receiving bin 19 of the polymer concrete mixer 24, into which the accelerator and the hardener flow from the tanks 25 and 26 through guide piping (28-30) and the binder 27.

The reactor 27 is connected by guide lines 34-36 to the containers 32 and 33 of synthetic binders and the capacity 31 of surfactant. According to the work program of the line, the composition of the polymer concrete in the reactor is mixed in the desired ratio according to the technical characteristics with different binders, and if necessary, surfactants are added. Binders are mixed at 50-55 ° C for 10 minutes.

In accordance with the program on the control panel of the polymer concrete mixer, all components of the polymer concrete composition — fillers, binder, accelerator and hardener — are metered simultaneously and mixed in a high-speed auger simultaneously.

The polymer concrete mixer 24 is feedback to the preparation of mineral fillers, as well as to the binder, accelerator and hardening systems, ensuring continuous operation during the shift.

After filling with polymer concrete, the mold moves mechanically driven on the roller conveyor 37 to the vibrating tables 38 and 39, where the polymer concrete mixture on the vibrating table 38 is compacted with a frequency of 100 Hz with an amplitude of 0.08-0.12 mm for 20-30 seconds, then the forms are moved to the second vibrating table 39, where it is compacted with a frequency of 100 Hz with an oscillation amplitude of 0.12-0.16 mm for 20-30 seconds. After vibrating the product on the roll table 37

sent to the polymerization chamber 41. The loader 40 of the polymerization chamber, operating in automatic mode, is filled with a multi-light chamber 41. After

holding the products in the polymerization chamber 41 for 1.5-2.0 hours, depending on the composition, they are unloaded by the unloader 42 and the form products are discharged by post 43, then the forms are cleaned at post 44. lubricated and sent along the conveyor 37 to post 46 fill.
