FIELD: process engineering.SUBSTANCE: invention relates to equipment for compaction of cut tobacco filler. Claimed press comprises at least one motor with control unit, compactor and drive. The latter allows transmission of force from motor to compactor. The latter is composed of a frame including two inclined lengthwise and two inclined crosswise elements and central part of lengthwise elements. Lengthwise elements are connected with inclined crosswise elements to make a through structure. The latter allows the air accumulated in cut filler to escape therefrom. Control unit adjusts the torque of at least one motor at displacement of compactor.EFFECT: optimised parameters of compactor, ruled out bulging of container for tobacco filler.6 cl, 7 dwg
FIELD: agriculture.SUBSTANCE: invention relates to a method and device for processing waste precipitate, such as biological tomatoes, vegetables, etc. or in reuse of precipitate appearing in agricultural works or biological cleaning water treatment, followed by restoring chemical, biological and mechanical treatment. The device for processing waste precipitate comprises an outer housing (2) hollow inside, an inner basic unit (3), a chamber (4) of compaction and dewatering inside the outer housing (2), along which the precipitate passes, the means (7) of the precipitate movement, which contributes to compaction and movement of the precipitate forward, at that the grid (11) in the form of a shell is a cathode, and the inner basic unit (3) is connected to the positive pole of the control unit and is an anode. The method of the precipitate processing comprises the steps of contributing to continuous movement forward and compacting the precipitate inside the compression chamber between the anode and the cathode, and setting the potential difference in order to expose the precipitate which is to be processed, to the electric field action.EFFECT: invention should ensure a high percentage of dry material with reduced costs.35 cl, 7 dwg
FIELD: process engineering.SUBSTANCE: invention relates to production of pellets used as combustible material. Pelletising press (3) comprises at least one female die (4) with multiple bores (13) for compaction of biomass (1) and at least one forming roller (5) running over said die (4). It includes at least one drive of female die (4) and/or roller (5). Female die (4) consists of at least two die segments (7, 7′…). To support said segments relative to roller (5) at least one support (9) is used. Said support (9) has at least one opening (8) for exit of pellets (10) from female die (4) bores (13). Butt edge (2) of female die segments is located at, in fact, at angle (16) to roller (5) swinging line (14) which is other than zero.EFFECT: termination of local damages or female die partial wear at minimum costs.19 cl, 7 dwg
FIELD: process engineering.SUBSTANCE: invention relates to press equipment for production of pellets from appropriate material. Pelletiser comprises carcass with main axle fitted therein, ring-shaped female die, rolls holder with axles running thereon. Pelletiser incorporates the drives. Every drive can inhibit roll axle displacement relative to female die holder to maintain the spacing between roll and die before application of force to roll axle that corresponds to pelletiser overload. Note here that said every drive includes hydraulic cylinder equipped with bypass valve connected therewith.EFFECT: accelerated operation, simplified overload protection.20 cl, 5 dwg
FIELD: process engineering.SUBSTANCE: invention relates to press equipment, particularly, to short-stroke press for production and/or lining of plate-shaped materials. This press comprises the bed composed of frame arranged in lengthwise direction of pressing, top and bottom plates. Working cylinders for loading of top and bottom plates are located on the frames to rest thereon and to be secured thereat. Rods fitted in frame recesses are used for attachment of working cylinders. Note here that rods and recesses are made for compliance to allow dismantling of rods between two appropriate pres frames.EFFECT: lower press servicing labour input.14 cl, 9 dwg
FIELD: process engineering.SUBSTANCE: invention relates to woodworking and can be used for production of sandwiched panels from sheets. Vertical press comprises the frame, support plate, portal and pressure plate. Columns are installed between portal props and connected with portal crossbar and said frame. Columns are provided with guides for vertical reciprocation of carriages. Supports are secured at said carriages and interconnected, provided with strut and horizontal belt rigidly secured at said carriage. Pressure plate is connected with the support horizontal belt. Support ends extending beyond said carriage are coupled with nuts of screw-nut pairs. Lead screws of said pairs are identical and have their ends articulated with the brackets arranged at column top and bottom. Lead screw lower ends have identical mutually engaged sprockets and engaged with sprocket fitted on reduction gear shaft. Said shaft is engaged by belt gearing with reversing motor drive.EFFECT: stack gluing process combined in time with preparation for gluing and unloading.9 cl, 4 dwg
FIELD: process engineering.SUBSTANCE: invention relates to extruders and can be used for production of fuel briquettes and planting peat pots. Claimed extruder comprises the frame with brackets for installing at the power means, drive mechanism with reduction gearbox and safety coupling and bin for process material to be loaded therein and variable-pitch auger, said extruder with said bin being mounted at said frame. End screw is mounted on output shaft of the latter and provided with rod fitted in conical adapter. Shutter is articulated with adapter end for intermittent closure by its plane the conical adapter outlet. End screw end does not extend to shutter plane at conical adapter outlet closed state by magnitude A equal to peat pot bottom depth. Note here that said shutter has the drive while its outline over perimeter is sharpened. Note also that said shutter can be detached while shims are fitted between said shutter and mating face.EFFECT: longer life, adjustable clearance between shutter plane and adapter outlet end face.3 dwg
