Description

The invention relates to the field of construction, as well as to the field of production of heat-insulating materials and can be used for the treatment of bricks made of foam.

A known installation for calibrating building products (see AS USSR No. 655505, class D 28 D 1/18. Publ. 09/15/1979. Bull. No. 13), containing a feed table, a device for four-sided longitudinal and butt transverse calibration, transporting live rolls, receiving conveyor. In addition, the installation is equipped with a guide device made in the form of rollers and stops mounted on both sides of the roller table and mounted on brackets.

For reasons that impede the achievement of the following technical result when using a known device, the fact that this device is applicable to the processing of dimensional products, such as building panels. In addition, this installation does not process the front surfaces of products.

A known installation for milling construction products (see AS USSR No. 431019, class B 28 D 1/18. Publ. 05.06.1974. Bull. No. 21), containing a feed table, lower and horizontally located mills, side vertically milling cutters - prototype.

For reasons that impede the achievement of the following technical result when using a known device, the fact that this device is applicable to the processing of dimensional products, such as building panels. In addition, the cylindrical end mills used in the device due to the short length of the working surface have low resistance, which leads to their frequent replacement and loss of productivity of the device.

The essence of the invention lies in the fact that the milling cutters for processing bricks are made of grinding wheels with a cutting cylindrical part, the first block being designed for simultaneous processing of small brick faces, the second block is for long brick ends, the third block is for brick front faces. The conveyor that transports the brick during processing consists of two parts, each individual conveyor conveyor equipped with pressure conveyors moving in the same direction as the conveyor conveyors.

In addition, each processing station is equipped with casings, which are connected via an air duct to a dust suction unit and to a cleaning device, for example, a pneumatic cyclone.

Using the proposed device provides the following technical result:

- increase processing performance;

- increase the dimensional accuracy of the processed bricks;

- improving the environmental safety of the installation.

The specified technical result in the implementation of the invention is achieved by the fact that the installation for processing foam diatomite bricks contains mills, transporting conveyor, guiding devices.

The feature is that the cutters are made in the form of blocks assembled from grinding wheels with a cutting cylindrical part, the first block being designed for simultaneous processing of short brick ends, the second block is for long brick ends, the third block is for brick front faces, and the conveyor conveyor consists in two parts, each individual conveyor belt equipped with pressure conveyors moving in the same direction as the conveyor belts.

In addition, each processing station is equipped with casings, which are connected via an air duct to a dust suction unit and to a cleaning device, for example, a pneumatic cyclone.

The analysis of the prior art by the applicant, including a search by patents and scientific and technical sources of information and identification of sources containing information about analogues of the claimed invention, allowed to establish that the applicant did not find an analogue characterized by features identical to all the essential features of the claimed invention. The definition from the list of identified analogues of the prototype, as the closest in the set of essential features of the analogue, allowed us to identify the set of essential distinguishing features in relation to the applicant's technical result in the claimed design set forth in the claims.

Therefore, the claimed invention meets the condition of "novelty."

The design of the invention is presented in the drawings:

figure 1 - kinematic diagram of the installation;

figure 2 is a section aa along the processing unit of the front sides of the brick;

figure 3 is a cross section BB on the processing unit of the long ends of the brick.

Installation for processing foam diatomite bricks contains a container 1, transporting conveyors 2 and 3, clamping conveyors 4 and 5, grinding blocks 6, 7 and 8, guides 9, 10, 11 and 12, rollers 13, casings 14, 15 and 16, air duct 17 , installation of dust suction 18, cyclone 19, container 20, container 21.

Installation works as follows.

After baking, the bricks from the container 1 are laid on a conveyor belt 2, which moves the brick into the processing zone. The grinding unit 6 simultaneously processes the short ends of the brick passing through the processing zone. In this case, the brick is pressed against the conveyor conveyor 2 by a pressure conveyor 6, and the conveyor belts are supported by rollers 13.

After processing one pair of ends, the brick falls to the conveyor conveyor 3, which is perpendicular to the conveyor conveyor 2. When the brick moves together with the conveyor conveyor 3, its long ends are simultaneously processed by the grinding unit 7.

The simultaneous processing of the front surfaces of the bricks is carried out by the grinding block 8. The guides 11 and 12 serve to eliminate the transfer of longitudinally moving bricks during processing. After processing, the bricks with the guide 10 are placed in a container 21.

The housings 14, 15 and 16 close the treatment zones and are connected to the air duct 17. Installing a dust suction 18 pulls the dusty waste out of the treatment zones and directs them to the pneumatic cyclone 19. As a result of the cyclone 19, the concentrated dust mass is dumped into the container 20, and the cleaned air is discharged into the atmosphere.

Thus, the use of a set of grinding wheels with a cutting cylindrical part as a tool increases the tool life, reduces the need for its frequent replacement, and thereby increases processing productivity.

Simultaneous processing of two opposite sides of a brick with a tool with a pre-set size on its cylindrical surfaces increases the dimensional accuracy of the brick.

The use of dust extraction devices from the processing zone increases the environmental safety of the proposed installation.

Thus, the foregoing description indicates the fulfillment of the following set of conditions when using the claimed invention:

- a tool embodying the claimed invention, in its implementation is intended for the treatment of bricks from penodiomatite;

- for the claimed device in the form as described in the stated claims, the possibility of its implementation using the means and methods described in the application is confirmed;

- a tool embodying the claimed invention in the implementation, is able to ensure the achievement of the perceived by the applicant of the assigned technical tasks. Therefore, the claimed invention meets the condition of “industrial applicability”.
