Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, and in particular to a waste crushing and recycling device. Background Technology

[0002] In the field of industrial waste recycling, traditional crushing equipment generally suffers from bottlenecks such as low continuous operation efficiency, excessive energy consumption, severe material mixing, and operational safety hazards. Although existing technologies attempt to optimize this through split collection bins or corrugated blades, they still have drawbacks such as difficulty in cleaning screening blockages, uneven particle size, and the risk of secondary pollution. Therefore, there is an urgent need to develop a waste treatment device that integrates axial multi-stage crushing blades to systematically improve crushing and recycling efficiency and operational safety.

[0003] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a waste crushing and recycling device that would have greater industrial value. Utility Model Content

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a waste crushing and recycling device.

[0005] This utility model discloses a waste crushing and recycling device, including a shell, an upper mounting plate on the top of the shell, a crushing motor fixed in the middle of the upper mounting plate, and multiple sets of crushing blades spaced apart along the axial direction mounted on the output shaft of the crushing motor; a waste collection box is detachably connected to the bottom of the shell, and a feed inlet is provided at the top, with the rotation trajectory of the crushing blades overlapping the feeding path of the feed inlet.

[0006] This waste crushing and recycling device adopts a modular structure design. The crushing motor is fixed to the top of the shell by an upper mounting plate. Multiple sets of spaced crushing blades are installed along the axial direction of the motor output shaft to form a stepped crushing area. The feed inlet is located at the top of the shell and the feeding path is precisely aligned with the rotation trajectory of the crushing blades to ensure that the material directly enters the crushing area of ​​the high-speed rotating blade group. The bottom of the shell is equipped with a waste collection box with a detachable connection. The crushed waste falls directly into the box under the action of gravity, realizing a vertical spatial layout of the entire process of "feeding-crushing-collection". This not only ensures the continuity of material processing, but also simplifies cleaning and maintenance operations through the modular collection box.

[0007] Furthermore, an openable dust cover is hinged above the feed inlet, and the size of the dust cover covers the opening area of ​​the feed inlet.

[0008] A hinged dust cover is attached above the feed inlet, which completely covers the opening area of ​​the feed inlet. The dust cover can be opened and closed by rotating around the axis through the hinge structure. During operation, the cover can be manually lifted to feed materials. When closed, it forms a continuous sealed surface with the edge of the feed inlet, effectively preventing dust and debris from escaping from the feed inlet in the opposite direction during the crushing process.

[0009] Furthermore, a horizontally arranged screen partition plate is provided below the crushing blade. The screen partition plate has screening holes evenly distributed in a matrix. The screen partition plate is located directly above the waste collection box and is slidably connected to the inner wall of the outer shell.

[0010] A horizontally arranged screen partition plate is installed below the crushing blade. Its surface has evenly distributed matrix-like screening holes, forming a particle size screening channel. The screen partition plate is fitted to the inner wall of the outer casing via a sliding connection structure and can be pulled out horizontally for easy cleaning of blockages or replacement with screen plates of different aperture sizes. This partition plate is located directly above the waste collection box. After being crushed by the blade assembly, the crushed material falls onto the screen partition plate. Smaller particles are intercepted and continuously crushed, while particles that meet the size requirements fall through the screening holes into the collection box below.

[0011] Furthermore, one end of the screen partition plate is provided with a pull handle that extends to the outside of the outer casing.

[0012] A pull handle extending to the outside of the housing is integrated at one end of the screen partition plate. The handle is rigidly connected to the screen partition plate body and exposed outside the equipment housing. Operators can move the screen plate horizontally by pulling the handle without touching the internal crushing chamber.

[0013] Furthermore, the multiple sets of shredder blades are arranged in a circumferential staggered pattern, and each shredder blade has an elliptical drag-reducing through hole in the middle of its blade.

[0014] Multiple sets of circumferentially staggered shredder blades are arranged with adjacent blades distributed with a phase difference along the rotation axis to form a continuous cutting trajectory to eliminate shredding blind spots. Each shredder blade has an elliptical drag-reducing through hole in the middle of its blade to reduce rotational aerodynamic resistance by reducing the blade's frontal area. At the same time, the blade mass distribution is optimized to improve dynamic balance accuracy.

[0015] Furthermore, the output shaft of the crushing motor is provided with a radially extending auxiliary lever. The auxiliary lever is made of stainless steel and is clearance-fitted with the upper surface of the screen partition plate, which is used to agitate the waste on the screen partition plate.

[0016] An auxiliary lever extending radially is added to the end of the output shaft of the crushing motor. This lever is made of stainless steel in one piece, featuring corrosion resistance and high rigidity. Its end maintains a dynamic clearance fit of 0.5-2mm with the upper surface of the screen partition plate. When the crushing motor is running, the auxiliary lever rotates synchronously with the shaft at high speed, periodically sweeping across the surface of the screen plate to apply centrifugal disturbance to the accumulated waste material, breaking up material agglomeration or screen hole blockage, while avoiding structural wear caused by hard contact.

[0017] By employing the above-described scheme, this invention possesses at least the following advantages: This waste crushing and recycling device, through the linkage design of a pull-out screen partition plate and an auxiliary lever, effectively prevents screen blockage and improves waste screening efficiency by utilizing the dynamic gap disturbance of the stainless steel lever. Furthermore, the external handle enables rapid disassembly and assembly of the screen plate, significantly reducing downtime for maintenance. Multiple sets of circumferentially staggered crushing blades, combined with a blade drag-reducing through-hole design, enhance the uniformity of material crushing while reducing motor power consumption by 15%-20%. The innovative synergistic optimization of each component overcomes the technical bottlenecks of traditional crushing equipment, such as easy screen blockage, high energy consumption, and cumbersome maintenance. The modular structural design extends the lifespan of key components, ultimately improving production efficiency and demonstrating significant application value in the field of solid waste treatment.

[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0025] See Figure 1Waste material enters the cavity of the outer shell 1 through the top feed inlet 6. The crushing motor 3 drives multiple sets of axially spaced crushing blades 4 to rotate at high speed. The material is crushed in multiple stages through the gradient shear force field formed between the blade sets. The design of the rotation trajectory overlapping with the feeding path ensures that the kinetic energy of the material is maximized in the initial contact stage. The crushed particles fall into the bottom waste collection box 5 through the gap between the blades. The detachable structure that completely covers the crushing area facilitates the centralized recycling of waste. The axially distributed crushing blades 4 achieve efficient crushing through dynamic overlapping cutting. The integrated feeding-crushing-collection process avoids secondary pollution. The detachable collection box 5 and the modular outer shell 1 greatly simplify cleaning and maintenance operations. The compact structure and directional feeding design achieve a waste volume reduction rate of more than 90% in a limited space, which has the characteristics of high processing efficiency.

[0026] The operator controls the feeding by manually opening and closing the dust cover 7 hinged above the feed inlet 6: when feeding, the cover is opened and waste material is put in; after closing, the cover 7 completely covers the opening of the feed inlet 6, forming a sealed state, effectively preventing dust from overflowing and foreign objects from entering during the crushing process; the dust cover 7 is made of lightweight and wear-resistant material, and when closed, it is tightly fitted to the edge of the feed inlet 6 by a silicone sealing strip, taking into account both ease of operation and sealing reliability.

[0027] See Figure 2 Particle grading control is achieved through the horizontally arranged screen partition plate 8 below the crushing blade 4: after crushing, the material falls to the screen partition plate 8 under gravity, and the matrix-distributed screen holes selectively screen the crushed particles. The qualified particles directly penetrate the screen holes and enter the waste collection box 5, while the unqualified coarse particles are blocked by the screen plate and are crushed again by the airflow generated by the rotation of the blade assembly. The design of the screen partition plate 8 slidingly connected to the inner wall of the outer shell 1 supports quick horizontal pulling and replacement of screens with different apertures, adapting to diverse waste treatment needs.

[0028] The screen partition plate 8 is designed to slide with the inner wall of the outer shell 1. After removal, residual debris can be quickly rinsed off, achieving tool-free disassembly and cleaning.

[0029] The screen partition plate 8 has a pull handle extending to the outside of the outer shell 1, which allows operators to quickly disassemble or reassemble the screen plate by pulling it horizontally with one hand without tools. After disassembly, the screening holes can be directly rinsed or replaced. The surface of the pull handle is equipped with anti-slip texture and limit marks to ensure that the force is applied evenly and the stroke is controllable during the pulling process.

[0030] The multiple sets of crushing blades 4 adopt a circumferential staggered arrangement design. During the crushing process, the trajectories of adjacent blades form a continuous shearing surface. The material is cut in three dimensions by the vortex field generated by high-speed rotation. The elliptical drag-reducing through hole in the middle of each crushing blade 4 can reduce the air resistance when the blade rotates and guide the airflow to accelerate the discharge of debris. At the same time, the stress dispersion effect of the hole edge can improve the bending strength of the blade.

[0031] A radially extending stainless steel auxiliary lever 9 is added to the end of the output shaft of the crushing motor 3. It maintains a 0.5-1mm gap with the upper surface of the screen partition plate 8. When the motor rotates at high speed, it periodically sweeps across the screen surface and breaks up the waste accumulation layer through mechanical actuation. The stainless steel material has high rigidity and corrosion resistance, and can withstand fiber entanglement and debris impact.

[0032] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.

Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0034] Finally: The above are only preferred embodiments of this utility model and are not intended to limit this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
