Abstract

Use: in the building materials industry for the manufacture of ceramic and clay bricks. SUMMARY OF THE INVENTION: A plant for the continuous manufacture of building products, comprises a frame, a chain conveyor with sprockets to which pallets supported on rollers are rigidly attached, forming with longitudinal and transverse sides of the mold, devices for feeding the mixture, forming, unloading the products, cleaning and lubricating the molds. The lateral sides of the form are made of two halves in the form of pivotal shutters fixed on racks. Horizontal pivot axes are parallel to the axis of the conveyor. At the free ends of the rack have rollers in contact with the copiers mounted on the frame. The conveyor has an additional sprocket installed behind the leader with the formation of an inclined section between them, to which a wedge-shaped scraper-device for unloading is located at an acute angle, contacting the inner surface of the forms. 7 il. 00

Description

The invention relates to the building materials industry, in particular to the manufacture of ceramic products, and can be used for the manufacture of ceramic and clay bricks and other products,

A known conveyor system for the manufacture of building products, comprising a frame, a chain conveyor with asterisks, pallets, longitudinal and transverse beams attached thereto, forming with the form pallets, devices for forming a moldable mixture, molding and unloading products, devices for cleaning and lubricating the form, are located under the lower branch of the conveyor 1.

In the known device, there is no complete cleaning of the pallet, which reduces the quality of the products.

This is achieved by the fact that the frame is provided with copiers, a conveyor-additional asterisk installed behind the leading asterisk with the formation of an inclined section of the conveyor between them, the unloading device is made in the form of a wedge-shaped scraper located at an acute angle to the inclined section of the conveyor and in contact with the inner surface of the forms, Devices for cleaning and lubrication in the form of cylindrical chips, while the transverse sides of the form are made of two halves in the form of rotary shutters fixed on racks, the horizontal The rotary axes of which are parallel to the axis of the conveyor, and at the free ends of the rack have rollers in contact with the copiers, with the sash in the working position placed between the longitudinal sides of the form above the joints

FIG. 1 shows the installation; in fig. 2 shows a section A-A in FIG. 1, along the axis of the blade metering drum of the bunker; in fig. 3 is a section BB in FIG. in fig. 4 shows a section B-B in FIG. 1 of a device for cleaning and smearing forms; in fig. 5 is a cross-section of the FIG. 1 with a cylindrical brush; in fig. 6 is a side view of the form; in fig. 7, - section DD in FIG. 6,

The plant for the manufacture of ceramic products is made in the form of a conveyor 1 with forms 2, above the upper branch of which components are placed to carry out the main technological process, namely: loading hopper 3, rotor 4 of vibro-molding, rotor-blowing agent 5. Under the lower branch 6 of the conveyor is placed a wedge-shaped scraper 7, located at an acute angle to the inclined section of the conveyor; a rotor 8 for cleaning and a device 9 for lubricating the molds.

Conveyor 1 is a four-way drive chain, on which, using the liner 10, U-shaped bases of 11 forms 2 are fixed. On the longitudinal sides of the 12 forms there are brackets 13 for the axles 14, on which the end boards of the form are turned. de two halves 15, to the base of which, on axles 16, there are attached rollers 17, which interact with copying guides 18 (Fig. 5). The molds 2 are supported on rollers 19 mounted on guides 20. A metering drum 21 with blades 22 is located in the loading hopper 3 (Fig. 1). The height of protrusion of the blades 22 above the cylinder of the drum 23 is regulated, which changes the amount of raw material falling asleep in form 2 (figure 1).

The cutting off of the quantity of raw material to be filled is also regulated by the sliding wall 24, and the removal of the raw material, cleaning the cylindrical surface of the drum 23 and the walls 24 of the drum, is carried out by scrapers 25.

The motion of the blades 22 is controlled by a copier 18. The rotors for cleaning and lubrication (pos.8 and 9, fig. 1) are cylindrical drums on which surfaces wire and hair brushes are fixed, driven by a chain drive from an asterisk. 26

Forms 2 move on rollers 19 along rails 20 in the direction of arrow E. When forms 2 pass through the technological cycle under the rotors of vibroblamping, vibrating rolling, vibrating formation and vibroextrusion, the end walls of the 15 forms are in the closed state, i.e. the final shape of the product is formed, which allows the rotor-conveyor line to re-adjust to different products in shape and compact the initial mass by moving the rotor vertically. When passing through the copiers 18, half of the 15 side edges of the molds are retracted on both sides of the pallet, from which the product is removed from the wedge-shaped scraper 7 and the pallet is cleaned,
