Description

Technical Field

[0001] This utility model relates to the field of waste sorting, and in particular to a highly stable and durable large-material air separator. Background Technology

[0002] In the treatment of bulky solid waste, crushers are often used to coarsely crush the waste into primary crushed material. This primary crushed material is a mixture of bulky materials, lightweight materials, and dust. It typically requires air separation equipment for initial sorting. Currently, bulky air separation devices often use the bent plates of the separator's guide chamber to directly contact the primary crushed material. However, this method has several drawbacks: First, bulky materials possess significant gravitational potential energy and downward kinetic energy, resulting in a large inertial impact on the bent plates of the air separator. The contact point experiences localized loading, bearing a large load, leading to poor equipment stability. The bent plates also break down quickly and are not durable, requiring frequent replacement and incurring high operating costs. Second, the bent plates are integral components, making spare parts expensive and bulky, and posing significant maintenance and replacement challenges. Third, the bent plates have low deformation capacity, posing a risk of blockage within the chamber, requiring frequent manual unblocking, which takes considerable time, resulting in short equipment stability and low equipment efficiency. Utility Model Content

[0003] To address one or more of the aforementioned problems, this utility model provides a highly stable and durable large-material air classifier.

[0004] According to one aspect of the present invention, a high-stability and durable large-material air classifier includes: a main frame, several wall panels, two buffer bases, a flow channel plate, and a protective plate; The main frame is a hollow rectangular three-dimensional steel structure frame; Several wall panels are fixedly connected to the four surfaces of the main frame. A group of opposite wall panels are provided with transverse protruding blocks. One of the wall panels is provided with a transverse feed inlet at the top and a transverse air inlet at the bottom. The buffer base has multiple large-sized positioning grooves on one vertical side and triangular blocks with equal vertical spacing on its opposite side. Triangular grooves are formed between adjacent triangular blocks. The two buffer bases are positioned opposite each other in the main frame. Their outer planes are attached to the inner wall of the wall panel and fixed by threaded parts. The positioning grooves are elastically interference-fitted with the protruding connecting blocks. The triangular grooves and triangular blocks of one buffer base are respectively aligned with the triangular blocks and triangular grooves of the other buffer base, forming a reciprocating bending cavity. The upper ends of the two buffer bases form a light material outlet and the lower ends form a heavy material outlet. The upper opening of one buffer base is aligned with the feed inlet and its lower opening is aligned with the air inlet. The flow channel plate includes several rectangular plates, which are fixedly attached to the inner side of the buffer base to form a reciprocating bending air separation channel. Each rectangular plate has a wear-resistant protective plate fixed to its outer wall, and an elastic rubber pad is provided between the two.

[0005] In some embodiments, the buffer base is an integral injection-molded block, and its positioning groove, triangular stop, triangular groove, upper opening and lower opening structural features are all formed during injection molding.

[0006] In some embodiments, the positioning groove is an isosceles triangular groove, and the triangular stop is an equiangular triangular protrusion; or the angle of the apex of the triangular stop is 45°-75°.

[0007] In some embodiments, a set of opposing wall panels are provided with multiple rows and columns of transverse first through holes, and the buffer base is provided with transverse connecting holes that cooperate with the first through holes. The ends of the transverse connecting holes are integrally injection molded to connect to nested nuts, and the first threaded component passes through the first through holes and the transverse connecting holes to connect to the nested nuts.

[0008] In some embodiments, the transverse connecting hole is an open blind hole, and a fixing groove for fixing and connecting the nested nut is formed at the end of the transverse connecting hole. The size of the fixing groove is larger than the diameter of the blind hole. The front and rear walls of the nested nut are provided with toothed structures, and the toothed structures are integrally injection molded to connect and fix the groove; the first threaded part is an internal hexagonal high-strength screw or an external hexagonal high-strength bolt.

[0009] In some embodiments, the wall panel is provided with multiple protruding blocks at equal vertical intervals. The outer surface of the buffer base is provided with multiple vertically spaced positioning grooves. The positioning groove and the protruding block are positioned opposite each other and are interference fit.

[0010] In some implementations, the convex block is a rectangular block or a dovetail block, and the positioning groove is a rectangular groove or a dovetail groove. The wall panels and the connecting blocks are fixedly connected or welded together by threaded parts.

[0011] In some implementations, the outline dimensions of each rectangular plate are the same as the outline dimensions of the upper and lower sides of the triangular block. Each rectangular panel has a rectangular rubber-plate-shaped elastic pad attached to its outer side; the protective plate is any one of high manganese steel ZGMn13, wear-resistant cast iron Cr15Mo3, or metal / ceramic composite plate.

[0013] In some implementations, the buffer base is any one of a rubber block, a nylon block, and a polyurethane block.

[0014] This highly stable and durable large-material air classifier features an integrated buffer base, while the flow channel plate and protective plate, which directly bear the load, are separate units. Its advantages are: First, the integrated buffer base can quickly and evenly distribute the large local inertial load of large materials into smaller, uniform loads before transferring them to the main frame and wall panels. Simultaneously, wear-resistant protective plates and elastic pads protect the rectangular partition plates, greatly improving equipment stability. The durable rectangular partition plates can be used for a long time without replacement, significantly reducing operating costs. Second, the separate flow channel plate and protective plate only require replacement of the damaged rectangular partition plate, reducing spare parts costs and size, and greatly simplifying replacement and maintenance. Third, the integrated buffer base increases the deformation of the bent wall panels. When there is a risk of blockage due to tower stacking within the cavity, subsequent feeding squeezes the lower end of the material, widening the cavity opening and automatically clearing blockages. This eliminates the need for frequent manual unblocking, resulting in a longer stable operating time and higher efficiency. Attached Figure Description
