Description

Briquette presses are known, in which endless ribbons are used as a pressing element, made up of separate interconnected links-forms and supported on a frame by means of rollers.

The proposed press makes it possible to improve the quality of pressing of briquettes, for which its rollers are connected together in an endless chain running around the frame during the operation of the press.

On fng. 1 shows a vertical briquetting press; FIG. 2 - press in section along A-A in FIG. one.

The briquetted material (coal, peat, ore, etc.) enters the press through a funnel / between two vertical tracks.

The two tracked blades move parallel to each other downward, tighten the compressible material and, due to the decrease in the distance between the links of the caterpillars, compress it. The caterpillar has the right of a web consisting of individual links 2, bounded on the sides by walls 3, which can be made as one piece with a track link or separate (removable) bolts. In the left track, link 4 has a protrusion pressing part, which enters with a certain gap between the side walls of the right track.

The links of the caterpillars are hinged to each other with the help of a pulling chain 5. A variant of the construction of links of single-molded caterpillars together with a pulling chain and connected along the edges with the help of fingers is possible. The working surface of the track links may have a removable lining of wear-resistant material or be deposited in places most subject to wear by a wear-resistant alloy, for example, stalinite.

The pitch of the track chain corresponds to the length of the track link, and the joints of the pressing surfaces of the links are made with a minimum and gaps between them in order to avoid pushing MaVepia a between the gaps of the links.

The fabric of the canvas is interconnected by a pair of cylindrical mecrepeil / 5. The finished briquettes are removed by the knife 7 and along the chute Ypodacs MA conveyor 9. To clean the tracked webs after the pre 9ran. , on single branches, cleaning steel brushes "/ С" are installed. Psess receives rotation through a reducer (not shown) and coupling 11, which transmits rotation to the lower drive shaft 12, on which two drive sprockets 13 are seated. /five. Upper driven sprockets 16 are seated on shafts 17 and rotated on roller bearings, which have a lower base with a wedge device 18 for tensioning the track chains.

The speed of the briquette tape is regulated in the range of 0.2-0.6 m / s by adjusting the speed of rotation of the engine.

Large pressing pressures are perceived by the support rollers / I that are interconnected by a flexible link-chain 20. Such a flexible roller chain is carried by the caterpillar, moves with it, and rolls along the frame during press operation. The length and diameter of the rollers are chosen according to the efforts of briquetting, depending on the material being briquetted. The ends of the rollers are mounted in a chain on the needle-and-iron accessories.

The pressing forces are transmitted through the support rollers to the support frames: right 21 and left 22, made of steel casting. The working part of the frame in the pressure zone has interchangeable pads 23 of more solid material. In the upper part of the frame there are devices for tensioning the chains of the roller wire. The arc 24 is rotated around the joint 25 with bolts 26. The right support frame rotates around the axis 27, which changes the distance between the tracks, and hence the thickness of the briquette. The left support frame on two axles x 28 and 29 is attached to the metal constructions of the press 30.

The right track axis 31 is connected by t-gams 32 to the yoke 33 through the axis 34. The yoke with the upper part rotates around the axis 35, at the bottom of the rocker arm passes 36 that are connected by the rocker 37 with the hydraulic lever 38.

The hydraulic cylinder 39 is supplied with oil from a hand pump.

To prevent the hydraulic jack system from being rigid, a powerful spring system 41 is installed between the belts 36 and the yoke 40, which perceives the variation in the thickness of the briquette tape as a shock absorber. All press assemblies are mounted on metal structures, the lower part of which is installed and poured on the foundation. From the efforts of pressing the metalwork is unloaded, the forces are perceived by the supporting frames 21 and 22 to close in connection with the frames.

The adjustment of the thickness of the briquette, depending on the material, is carried out by shifting down or up the inner strips 42 of the feed funnel 1, this changing the initial thickness of the layer covered in the tracks.

At the top of the press, the tracks disperse so that the side spaces are between. they are made open, so these places are closed by side shields 43 with seals from the material being poured out.

In the case of forcing the briquetted material into the gap between the joints of the links, grooves 44 are provided along the entire perimeter of the links, from which the extruded ribbon is removed when bent

caterpillars of stars. Such a device prevents material from accumulating between the tracks' joints, and therefore protects the traction chain from spacer forces.

To cut the briquette tape to a certain size, teeth 45 were made at the left links of the tracks in the working pressing part, which made the tape notch. On these cuts, the briquette tape breaks as it bends around the lower drive sprockets. The length of the briquette is respectively equal to the pitch of the track.
