BG65540B1 - Briquetting device - Google Patents

Abstract

The briquetting device is designed to press crushed plant material, such as wood particles, cut sunflower and maize stalks, straw, organic waste from the vegetable oil production, etc., and it can find application in the use of waste plant materials in everyday life. It is with a technological design ensuring the realization of a working space enclosed on all sides throughout the pressing cycle. The device consists of four wedge pistons (10) shaped as triangular prisms with beveled circumferential edges, two of the adjacent surrounding surfaces of which are mutually perpendicular and sloped to the third one under an angle of 45 degrees and located in a square hole on a square body. The latter is shaped inside two lateral carriers (3), a front carrier (11) and a rear carrier (1) fastened to each other by screws, so as to allow the third surrounding surface to slide on the wall of the square hole of length L. The mutually perpendicular surfaces of each piston (10) get into contact and slide over the mutually perpendicular surfaces of the adjacent wedge pistons (10), while one of them is a wall of a square-section working space.

Description

Technical field

The invention relates to a briquetting device, and in particular to a device for the compression of fragmented plant materials - wood particles, chopped sunflower and corn stalks, straw, organic waste from the production of vegetable oils and can be used in the use of waste vegetable materials in bits.

BACKGROUND OF THE INVENTION

A device [1] is known by which the briquetting is accomplished by means of three pairs formed as a regular truncated quadrangular pyramid piston, which are spaced apart on the supports so that their small bases are opposite each other and the geometric axes of each pair pistons to intersect at the geometric center of the pressed briquette. The carriers carry out simultaneous and synchronous displacement of the pistons towards the geometric center of the briquette or in the opposite direction, whereby the briquette is pressed or the device for loading a new dose of compression material is opened. In this device there is a gap between the surrounding surfaces of the pyramid-shaped pistons at each stage except the final pressing stage, which predetermines the inability to be used for pressing bulk and fragmented materials, as well as to realize a different degree of compacting of the briquettes without changing on the pistons.

SUMMARY OF THE INVENTION

The object of the invention is to provide a device for briquetting fragmented materials, whereby the pressing can be achieved by touching without slack at each moment of pressing sliding in one plane relative to each other, which synchronously, simultaneously and sequentially reduce to different degrees when pressed or enlarged at opening without changing the pistons, the dimensions of the cross-section of the workspace in which the pressing material is first housed and subsequently pressed oic preform. The synchronized movement of the pistons should also determine the simultaneous four-sided application of the compression force required for briquetting.

The problem is solved with a briquetting device made up of four uniformly shaped and sized wedge-shaped pistons, shaped as triangles, inclined along one circumferential edge by prisms, two of the adjacent circumferential surfaces of which are mutually perpendicular but inclined towards the third at an angle of 45 °. The pistons are mounted in a square hole of length L per square body, formed by assembled one to another and screwed two side, front and rear supports so that the third surrounding surface slides along the wall of the square shaped opening and the perpendicular surfaces of each piston touching and sliding along the mutually perpendicular but different surfaces of the adjacent wedge pistons, one of them being a square-sectioned workspace wall.

From the outer surrounding walls of the square housing with screws are attached four power cylinders, whose pistons, passing through openings made in each carrier, are connected by a threaded connection to the wedge pistons.

To the shaped square housing with screws are mounted upper and lower lid, in the channels of which are mounted upper and lower slides, sliding through two pistons of two hydraulic cylinders in a direction perpendicular to the front and rear carrier until they match when loading or fully closed when pressed of the square openings formed in the lids and slides.

The main advantages of the briquetting device are the manufacturability of the construction, provided by the use of the same four prismatic pistons in one plane and the realization during the whole cycle of pressing of a closed space on all sides, creating the conditions to press bulk and fragmented materials in four-sided application of the pressing effort.

An embodiment of the invention

The briquetting device is composed of four wedge-shaped pistons 10, shaped as triangles, slanted along one circumferential edge by sliding into one plane prisms, two of the adjacent circumferential surfaces of which are mutually perpendicular, but inclined towards the third at an angle of 45 °. The pistons 10 are mounted in a square opening of a square housing formed by two side 3 screws 1, 11 front and rear 1 mounted by screwed together so that the third circumferential surface slides along the square hole of length L, and the perpendicular surfaces of each piston 10 touch and slide along the mutually perpendicular but different surfaces of the adjacent wedge pistons, one of which being a square-sectioned workspace wall. From the outer surrounding walls of the square housing are bolted to power cylinders 5 whose pistons 4, by passing through a hole made in each carrier, are threaded to the wedge pistons 10. They are screwed to the upper and lower sides of the shaped square housing by screws. mounted upper 6 and lower 2 lid, in grooves of which the upper 7 and lower 12 slides are mounted, sliding through two pistons 8 of the hydraulic cylinders 9 in a direction perpendicular to the front 11 and the rear 1 carrier to coincide or completely close the formed in the lids a gate and square holes.

Use of the invention

The device operates in the following order - loading the workspace with a fragmented material from a conveyor, pressing the briquette, opening the workspace and freeing the workspace from the pressed briquette.

The loading of the workspace is realized with the maximum open position of the wedge pistons 10, the closed lower 12 and the upper 7 open. The compression of the crushed and loaded material into the workspace to the briquette is done with the closed slides 7 and 12. The wedge pistons 10, under the action of the pistons 4 and the power cylinders 5, sliding along the contact surfaces, shrink the work space to the size of the pressed briquette.

The opening and subsequent gravitational release of the workspace from the pressed briquette is done with the lower slide 12. The slide is closed 12. The pressing cycle is repeated for pressing new briquettes.
