Description

Technical Field

[0001] The present invention relates to the technical field of solid waste, and particularly relates to a solid waste extrusion and recycling device. Background Art

[0002] There are solid wastes in sewage treatment. When recycling solid wastes, they usually need to be crushed into smaller pieces for easy transportation and subsequent treatment.

[0003] For example, Chinese Patent CN117160625B, a solid waste crushing device, belongs to the technical field of solid waste crushing. To solve the technical problem of low crushing efficiency when the existing technology crushes solid waste containing plastic bottles; through the setting of a guiding component, a driving component, a partition board, and a puncturing component, when the motor is started, the five groups of partition boards all rotate. The solid waste is evenly transported between the five groups of partition boards through an external conveying structure. The extrusion arc plate can drive the steel needles to pierce the solid waste, and can squeeze the plastic bottle flat. As the partition board continues to rotate, the extrusion arc plate will approach the transmission shaft. When the solid waste coincides with the falling hole, blanking can be realized. The solid waste can fall on the two groups of shredding parts for crushing through the guiding of the two groups of guiding plates, and can be crushed after squeezing the plastic bottle flat, so as to improve the efficiency of solid waste crushing.

[0004] Although the above structure can play a role in crushing solid waste, when there are uncompletely crushed solid wastes, they cannot be crushed twice, and the phenomenon of incomplete crushing is likely to occur. Secondly, the water content of solid wastes in sewage treatment plants is relatively high. The above structure does not design an extrusion and drainage structure, and the crushed solid wastes are heavy or cause relatively large air pollution and breed germs.

[0005] Based on this, the present invention designs a solid waste extrusion and recycling device to solve the above problems. Summary of the Invention

[0022] Beneficial effects

[0023] In the present invention, solid waste is added into the crushing box. The crushing component of the automatic feeding and extrusion assembly crushes the solid waste. At the same time, the crushing component drives the shaking and screening component to shake. The crushed materials fall onto the shaking and screening component, and the shaking and screening component performs shaking and screening treatment. Shaking is helpful for full screening. The materials that do not pass through the shaking and screening component enter the lifting component. The lifting component transports the materials that do not pass through the shaking and screening component to the crushing component for secondary crushing, ensuring the crushing effect. When extrusion is required, the pressing structure resets to the unpressurized state, and the self-resetting baffle structure moves to the discharge port of the pressing structure through its own restoring force to block the discharge port of the pressing structure. The materials passing through the shaking and screening component in the crushing box enter the pressing structure of the automatic feeding and extrusion assembly. The pressing structure and the self-resetting baffle structure cooperate to extrude the materials. After extrusion, the pressing structure resets to the unpressurized state. During the reset process, the pressing structure drives the self-resetting baffle structure to open the discharge port of the pressing structure. The extruded materials fall into the first straight tube and are discharged by their own gravity. When the pressing structure resets to the unpressurized state, the self-resetting baffle structure separates from the pressing structure and moves to the discharge port of the pressing structure through its own restoring force to block the discharge port of the pressing structure, realizing the squeezing and water treatment of the crushed solid waste. At the same time, it is convenient to automatically discharge the extruded materials, reduce the weight of the crushed solid waste, and avoid causing serious air pollution and breeding germs, etc. Description of the drawings

Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0043] The present invention will be further described below with reference to the embodiments.

[0044] Embodiment 1. Please refer to Figures 1 - 13 , a solid waste extrusion and recycling device, including a crushing box 1:

[0045] The crushing box 1 is connected with a cyclic crushing assembly 3 for material crushing, screening and secondary crushing;

[0046] The cyclic crushing assembly 3 includes a crushing assembly, a shaking screening assembly and a lifting assembly. The crushing assembly for material crushing is connected with the crushing box 1, and the crushing end of the crushing assembly is located inside the crushing box 1. The crushing assembly is connected with the shaking screening assembly for screening the crushed material and the lifting assembly for lifting the material that has not passed through the shaking screening assembly onto the crushing assembly.

[0047] The bottom of the crushing box 1 is connected with an automatic feeding type extrusion assembly 2 for extrusion drainage and automatic discharging;

[0048] The automatic feeding type extrusion assembly 2 includes a self-resetting baffle structure, a pressing structure and a first straight cylinder 23. The pressing structure is connected and communicated with the discharge port of the crushing box 1. The discharge port of the pressing structure is connected with a self-resetting baffle structure. The discharge port of the pressing structure is connected with a first straight cylinder 23 for discharging solid materials, and the self-resetting baffle structure is in sliding connection with the top of the first straight cylinder 23 in a fitting manner.

[0049] Solid waste is added into the crushing box 1. The crushing component of the automatic feeding type extrusion component 2 crushes the solid waste. At the same time, the crushing component drives the shaking and screening component to shake. The crushed material falls onto the shaking and screening component, and the shaking and screening component conducts shaking and screening treatment. Shaking and screening helps to fully screen. The material that does not pass through the shaking and screening component enters the lifting component. The lifting component conveys the material that does not pass through the shaking and screening component to the crushing component for secondary crushing, ensuring the crushing effect. When extrusion is required, the pressing structure resets to the non-pressed state, and the self-resetting baffle structure moves to the discharge port of the pressing structure through its own restoring force to block the discharge port of the pressing structure. The material passing through the shaking and screening component in the crushing box 1 enters the pressing structure of the automatic feeding type extrusion component 2. The pressing structure and the self-resetting baffle structure cooperate to extrude the material. After extrusion, the pressing structure resets to the non-pressed state. During the reset process, the pressing structure drives the self-resetting baffle structure to open the discharge port of the pressing structure. The extruded material falls out through the first straight cylinder 23 by its own gravity. When the pressing structure resets to the non-pressed state, the self-resetting baffle structure separates from the pressing structure and moves to the discharge port of the pressing structure through its own restoring force to block the discharge port of the pressing structure, realizing the squeezing and water treatment of the crushed solid waste. At the same time, it is convenient to automatically discharge the extruded material, reduce the weight of the crushed solid waste, and avoid causing large air pollution and breeding bacteria, etc.

During the reset process of the L-shaped pushing plate 214, the cross plate 26 drives the straight plate 27 to move, the straight plate 27 drives the L-shaped plate 28 to move, the L-shaped plate 28 drives the second straight cylinder 217 to move through the trapezoidal plate 216, and the second straight cylinder 217 drives the second spring 218 to move along the guide rail 25. The first spring 211 is compressed, and the self-resetting baffle structure opens the discharge port of the pressing structure. After extrusion, the material falls to the first straight cylinder 23 by its own gravity and is discharged.

[0065] When the trapezoidal plate 216 moves to the push rod 210, the trapezoidal plate 216 contacts the inclined surface of the push rod 210 and pushes the trapezoidal plate 216 towards the second straight cylinder 217. When the bottom of the trapezoidal plate 216 is at the top of the L-shaped plate 28, the L-shaped plate 28 separates from the trapezoidal plate 216, and the L-shaped plate 28 continues to move. The restoring force of the first spring 211 pushes the movable baffle 215 to move to the discharge port of the pressing structure to block the discharge port of the pressing structure, realizing the extrusion treatment of the crushed solid waste, and at the same time, facilitating the automatic discharge of the extruded material.
