Description

FIG g

316.18132

The invention relates to the production of building materials, in particular to the manufacture of large-sized building blocks.

The purpose of the invention is to reduce energy consumption in the production of large-sized blocks.

Figure 1 shows the installation, General view; figure 2 - the same plan; Yu on fig.Z - section aa in figure 2; figure 4 - view B in figure 1.

The line includes three successively installed grinders 1, a humidifier 2, a horizontal press 15 3, a cutting device 4 the first conveyor of raw blocks 5 with a casing b, a second conveyor 7. with a platform for accommodating the dried blocks 8, a mobile oven 9 about 20 hectares stand 10, with a channel 11, which is connected to the casing 6.

Grinders 1 are made in the form of two inclined 25 angled to the horizon 12 mounted 25 of the individual strips 13. Moreover, the thickness of the strips 13 of each next crusher is smaller than the previous one.

Press 3 is made in the form of a set loading hole. Under the action of the stamp 14, the clay is compressed and formed as a bar, which advances through the cores 15. The solid bar coming out of the press 3 is cut into blocks 1 m long in the cutting tool 4. The temperature of the blocks is. The drying of the blocks is carried out on the first conveyor 5 in the casing 6, into which gases from the kiln 9 flow through channel 11.

The dried blocks from conveyor 5 are fed to conveyor 7 moving in the opposite direction. From transport 7, the blocks are shifted to platform 8, and then moved to stand 10, for example, by a truck crane. I

Before installing the blocks on the stand, the slots of the channel 11 are covered with sliding paper to prevent cold air from being sucked into the channel 11. The paper burns during firing. At the same time, that part of the channel 11, where the burned blocks are located on the stand 10, is separated by a gate 18 mounted on the furnace 9. Along the stand 10

The body of the die 14 and located-30 moves along the rails 16 of the cores fired opposite it 15. Furnace 9. Heating of the furnace 9 carried out The furnace 9 of burning is installed by burning fuel in the nozzles 17. installed in the middle part of the furnace. The temperature in the middle zone is about 900 ° C. The furnace 9 moves from one end of the stand 10 to the other. The burnt blocks are removed and, in their place, dried blocks are placed on stand 10 from platform 8. On conveyor 7, platform 8 and stand 10, the blocks are cooled and finally dried.

rails 16 for moving along stand 10. The furnace 9 is equipped with nozzles 17 for burning fuel and gates 18 to separate the part of the channel 11 above which the burned blocks are located.

The device works as follows.

The material for the manufacture of building blocks enters the grinder 1, in which, due to the movement of the cheeks 12 towards each other, the material is crushed, screened, mixed and the solid inclusions are separated. To increase the degree of grinding, several grinders have been installed in series. Then the material enters the steam humidifier 2, where the clay is moistened and heated with saturated low pressure steam (0.3-0.5 atm). As a result of steaming, the molding properties of clay improve, it warms up to 60 ° C, which reduces

drying time by 40-50%.

From paroollaetnitel 2 material is blunt into the press at the time of opening the operating hole. Under the action of the stamp 14, the clay is compressed and formed as a bar, which advances through the cores 15.
