Abstract

FIELD: construction, applicable for working of foam-diatomite bricks.

SUBSTANCE: the rotary line has milling cutters for successive working of the brick surfaces, transporting conveyer, guide fixtures, manipulator. The milling cutters are made in the form of blocks set up of cutting-off side milling cutters with a cutting cylindrical section. The transporting conveyor is made of three drums. The first drum is designed for transporting the brick to the area of working of the shorter ends. The second drum is designed for transporting the brick to the area of working of the longer ends of the brick. The third drum is designed for transporting the brick to the area of working of the brick face sides.

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 technical result indicated below when using a known device, this device is applicable to the processing of dimensional products, for example, 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 cutters, side vertically located milling cutters, side vertical milling cutters - prototype.

For reasons that impede the achievement of the technical result indicated below when using a known device, this device is applicable to the processing of dimensional products, for example, 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 in the form of blocks drawn from cutting wheels with a cutting cylindrical part, the first block being used for simultaneous processing of short brick ends, the second block for long brick ends, and the third block for brick front faces , and the conveyor conveyor is a set of drums of three pieces, where the first drum is designed to transport bricks to the processing zone of short ends, the second drum to the processing zone innyh ends of the bricks, the third drum - in the treatment zone facing sides of the brick.

To turn the brick during its transition from one drum to another, tilters are installed.

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:

- Improving processing performance;

- Improving the dimensional accuracy of the processing of 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 rotor line for processing foam diatomite bricks contains mills, conveying conveyor, guiding devices.

The feature is that the milling cutters are made in the form of blocks assembled from detachable disk mills with a cutting cylindrical part, the first block being used for simultaneous processing of short brick ends, the second block for long brick ends, the third block for front brick faces and the conveyor conveyor is a set of drums of three pieces, where the first drum is designed to transport brick to the processing zone of short ends, the second drum to the processing zone of long brick ends, the third drum - treatment zone facing sides of the brick. In addition, tilters are installed between the drums, and each processing station is equipped with casings, which are connected via a duct to a dust extraction 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 end short sides of the brick;

figure 3 is a cross-section BB on the processing unit of the end long sides of the brick;

figure 4 - section BB in the processing unit of the front sides of the brick.

The rotor line for the treatment of foam diatomite bricks consists of containers 1, 2 and 3, rotors 4, 5 and 6, blocks 7, 8 and 9, assembled from cutting mills, tilters 10 and 11, guides 12, 13, 14 and 15, casings 16, 17 and 18, air duct 19, installation of dust extraction 20, cyclone 21.

The device operates as follows. Ready after firing, the bricks from the container 1 are placed on the guides 12, and then collide on the rotor 4, which moves the brick into the processing zone. Block cutters 7 simultaneously processes the short ends of the brick passing through the processing zone. After processing one pair of ends, the brick falls onto the guides 13, then falls into the tilter 10, where the brick is rotated 90 ° around the vertical axis.

The newly oriented brick is directed to the rotor 5, which moves the brick to the next processing zone. Block cutters 8 simultaneously processes the long ends of the brick passing through the processing zone. After processing, the brick falls onto the guides 14, and then falls into the tilter 11, where the brick is rotated 90 ° around the longitudinal axis. The newly oriented brick is directed to the rotor 6, which moves the brick to the next processing zone. Block cutters 9 simultaneously processes the front side of the brick passing through the processing zone. After processing, the brick falls onto the guides 15, and then fits into the container 2.

Thus, the use of a block of cutting mills 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 end 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 technical tasks.

Therefore, the claimed invention meets the condition of “industrial applicability”.
