Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of spiral extrusion, more particularly, to a spiral press. BACKGROUND

[0002] With the rapid development of the automobile industry, the use of automobile oil filters has increased significantly, and the demand for their recycling has become increasingly urgent. In the process of disassembling and recycling oil filters, spiral extruders are widely used in the oil filtering process. They use a spiral propulsion structure to extrude the filter core under high pressure to separate and recycle the waste oil. However, in actual application, it is found that after the existing spiral extruder completes the oil extraction, the extruded filter core residue is prone to form a blockage at the outlet, leading to frequent equipment downtime maintenance, which seriously affects production efficiency and the stability of subsequent processing procedures.

[0003] After the filter core material (such as paper-based, metal mesh, or composite material) is extruded under high pressure, the fiber structure or metal scraps are easily formed into loose or dense residue lumps at the outlet due to elastic recovery or friction, causing physical blockage.

[0004] The above blockage problem not only leads to unplanned equipment downtime, increasing the cost of manual cleaning, but also may cause secondary shedding of residues to pollute the subsequent recycling system, reducing oil purity. In addition, frequent downtime maintenance reduces overall recycling efficiency, increases energy consumption and equipment wear and tear, and seriously restricts the sustainable development of the automobile oil filter circular economy industry chain. CONTENT OF THE INVENTION

[0005] Based on the above problems, the present application proposes a spiral press to solve the technical problem that the extruded filter core residue is prone to form a blockage at the outlet, leading to frequent equipment downtime maintenance, which seriously affects production efficiency and the stability of subsequent processing procedures.

[0006] To solve the above technical problems, the technical scheme adopted by the present application is:

[0007] A spiral press, comprising a mounting frame, a pressing barrel mounted on the mounting frame, a spiral shaft mounted in the pressing barrel, a spiral blade mounted on the spiral shaft, a feed inlet and a discharge outlet provided on the pressing barrel, and a discharge auxiliary structure provided on the discharge outlet.

[0008] The auxiliary structure comprises a mounting shell mounted on the discharge port, a rotating shaft is arranged in the mounting shell, two rotating shafts are arranged, a discharge brush is arranged on each rotating shaft, a driving gear is arranged on one rotating shaft, a driven gear is arranged on the other rotating shaft, the driving gear and the driven gear are engaged, a mounting seat is arranged below the mounting frame, a first motor is arranged on the mounting seat, a power gear is arranged on the power output end of the first motor, and the power gear and the driving gear are engaged.

[0009] In a specific embodiment, at least one discharge brush is arranged on each rotating shaft, and each discharge brush is arranged at different angles.

[0010] In a specific embodiment, the diameter of the inlet end of the pressing barrel is greater than the diameter of the outlet end, and the diameter of the inlet end gradually decreases to the diameter of the outlet end.

[0011] In a specific embodiment, the spiral shaft penetrates the pressing barrel and is rotatably connected between the mounting frames.

[0012] In a specific embodiment, a crushing structure is arranged on the inlet, and the crushing structure is in communication with the inlet.

[0013] In a specific embodiment, a first pulley is fixedly arranged on one end of the spiral shaft close to the inlet, a second motor is arranged on the mounting frame, a second pulley is arranged on the power output end of the second motor, a third pulley is arranged on the crushing structure, the second pulley and the first pulley are connected through a transmission belt, and the first pulley and the third pulley are connected through a transmission belt.

[0014] In a specific embodiment, an oil outlet is arranged at the bottom of the pressing barrel, at least one oil outlet is arranged, and an oil baffle is arranged below the oil outlet.

[0015] The positive effects of the utility model are as follows:

[0016] After the spiral extrusion is completed, when the residues flow to the discharge port along with the waste oil, the discharge brush breaks the adhesion of the residues through high-frequency reciprocating motion (the rotating speed can be adjusted through the first motor), so that the residues are prevented from accumulating at the outlet.

[0017] Different angle bristles enhance the cleaning coverage range and eliminate dead angles, especially for the winding problem of fiber residues.

[0018] The diameter of the inlet end is greater than the diameter of the outlet end, forming a conical structure, the pressure in the cavity is increased through the decrease of the cross-sectional area, and the filter core residues are more tightly discharged under high pressure.

[0019] The filter core is preliminarily broken into fine particles by the third belt wheel driven crushing blade (such as a rotating tooth blade or a hammering structure in the crushing structure), so as to facilitate subsequent extrusion and discharge. BRIEF DESCRIPTION OF DRAWINGS
