Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, and in particular to a multi-layer structure for construction waste with a decontamination and reverse filtration function. Background Technology

[0002] With the acceleration of urbanization, the amount of waste generated during construction and daily renovation is constantly increasing. This type of waste has a complex composition and usually includes a mixture of various materials such as ash, broken bricks, wood, plastic packaging, paper debris, and household waste.

[0003] To avoid pollution to the construction environment and surrounding areas, construction waste often needs to be collected and transported centrally. First, the types of waste are mixed, and dry and wet separation is usually not carried out. Wet waste is easily stuck together with ash and soil, making subsequent cleaning and transportation difficult. Second, lightweight materials such as plastic products, wood chips, and packaging bags are mixed in, which not only make the waste bulky, but also easily entangle or block transportation vehicles, increasing cleaning resistance. As a result, the volume of waste is not effectively compressed, and the weight and moisture are uneven, which is not conducive to subsequent reuse or centralized treatment. Utility Model Content

[0004] The technical problem this utility model aims to solve is that existing waste disposal methods suffer from mixed waste, difficulty in separating wet and dry waste, and high transportation resistance, resulting in low processing efficiency and hindering subsequent processing.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a multi-layer structure for construction waste with decontamination and reverse filtration function, including a main compartment, which is a rectangular compartment structure with two inlets at the top and a through slot at the bottom, and the two inlets and the slot are interconnected. An auxiliary compartment is inserted into the inlet at the top of the main compartment, and the bottom of the auxiliary compartment is connected to one of the inlets. Two rotating motors are fixedly installed on one side of the main compartment, and a crushing blade is fixedly installed at the output end of the rotating motor. The auxiliary compartment is a detachable upper and lower compartment. Multiple sliding blocks are fixedly installed on one side of the lower part of the auxiliary compartment. Multiple vertically arranged support plates are fixedly installed on one side of the main compartment, and the upper part of the auxiliary compartment is fixedly connected to the support plates. A groove for the sliding blocks to slide up and down is opened on one side of the support plate. A push rod motor is fixedly connected to the upper part of the auxiliary compartment. A filter pressure plate is fixedly connected to the output end of the push rod motor, and a pressure-bearing mesh plate is snapped into the top of the lower part of the auxiliary compartment.

[0006] As a further improvement of this utility model, ear plates are fixedly connected to both sides of the pressure-bearing mesh plate, and a slot that engages with the ear plates is fixedly provided on the lower inner wall side of the auxiliary compartment.

[0007] As a further improvement of this utility model, the outer side of the support plate is threaded with a combination bolt, which is fastened to the sliding block.

[0008] As a further improvement of this utility model, the material crushing blade is fixedly installed on the outer wall of the output end of the rotating motor, and the material crushing blade is configured as a spiral blade structure with the blade edge being sharpened.

[0009] As a further improvement of this utility model, support side plates are fixedly provided on both sides of the main compartment, and the support side plates are configured as a C-shaped double-layer clamping plate structure.

[0010] As a further improvement of this utility model, the two sides of the supporting side plate are threaded with mounting bolts.

[0011] The beneficial effects of this invention are as follows: By combining an auxiliary chamber, a filter press, and a shredder rotor above the main chamber, continuous processing of construction waste—compression, solid-liquid separation, and shredding—is achieved. When the pusher motor drives the filter press downwards, it effectively squeezes out the water from the wet waste, allowing the liquid to drain quickly while retaining the solid waste, thus avoiding increased weight and transport burden due to high water content. Subsequently, workers place the compressed solid waste into the main chamber, and the motor drives the shredder rotor to cut and shred the solid waste, significantly reducing the volume of lightweight materials and preventing impurities such as plastics, wood chips, and packaging bags from entangled or clogging transport vehicles. The overall structure realizes an integrated processing flow from feeding, compression, separation to shredding, effectively reducing the volume and weight burden during transport and improving the efficiency and economy of waste treatment.

It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] This utility model provides a multi-layer structure for construction waste with a decontamination and reverse filtration function, including a main compartment 1;

[0021] As attached Figure 1 , 3 As shown, the main hopper 1 is a rectangular structure with two loading ports at the top, one of which connects to the bottom of the auxiliary hopper 2. The bottom has a through-slot, and both loading ports connect to the slot. Supporting side plates 11 are fixedly installed on both sides of the main hopper 1, and these side plates 11 have a C-shaped double-layered structure; they can support the main hopper 1 onto the working frame. The supporting side plates 11 are threaded with mounting bolts on both sides to reinforce the connection between the main hopper 1 and the working frame. The auxiliary hopper 2 is inserted into the top of the main hopper 1. One side of the auxiliary hopper 2 has a hinged door for material loading. Two rotating motors 3 are fixedly installed on one side of the main hopper 1. A material crushing blade 4 is fixedly installed at the output end of each rotating motor 3, located on the outer wall of the output end of the rotating motor 3. The material crushing blade 4 has a spiral blade-like structure with sharpened edges; it provides material crushing processing.

[0022] As attached Figure 1 , 2As shown in Figures 3 and 4, the auxiliary chamber 2 is a detachable upper and lower chamber design. Multiple sliding blocks 5 are fixedly installed on one side of the lower part of the auxiliary chamber 2, and multiple vertically arranged support plates 6 are fixedly installed on one side of the main chamber 1. Combined bolts are threaded onto the outer side of the support plates 6, and these combined bolts are fastened to the sliding blocks 5; this provides a limiting effect between the main chamber 1 and the auxiliary chamber 2. The upper part of the auxiliary chamber 2 is fixedly connected to the support plates 6, and one side of the support plates 6 has a groove for the sliding blocks 5 to slide up and down. A push rod motor 8 is fixedly connected to the upper part of the auxiliary chamber 2, and the push rod motor 8 is preferably a hydraulic push rod motor with a thrust range of 20–40 kN and a working pressure of 10–16 MPa. A filter pressure plate 9 is fixedly connected to the output end of the push rod motor 8, and a pressure-bearing mesh plate 10 is snapped onto the lower top of the auxiliary chamber 2; this provides solid-liquid separation. The pressure-bearing mesh plate 10 is fixedly connected to the ear plates 7 on both sides, and the lower inner wall of the auxiliary compartment 2 is fixedly provided with a slot that engages with the ear plates 7; after the lower part and the upper part of the auxiliary compartment 2 are separated, the lower part and the upper part of the auxiliary compartment 2 can be separated through the ear plates 7 and the slot.

[0023] Working principle: In the specific implementation of this utility model, firstly, mixed waste such as plastic products, wood chips, and packaging bags generated at the construction site are placed into the auxiliary compartment 2. A waste liquid receiving container is installed at the groove below the main compartment 1. The auxiliary compartment 2 is stably limited and fixed by a combination bolt and a sliding block 5 to ensure a reliable connection between the auxiliary compartment 2 and the support plate 6. Subsequently, the push rod motor 8 is started and drives the filter plate 9 to move downward. Under the support of the pressure mesh plate 10, the waste is compressed. The filter plate 9 filters out the water in the wet waste through the pressure mesh plate 10 and collects the waste liquid through the waste liquid receiving container located at the bottom of the groove, thereby achieving preliminary solid-liquid separation. Subsequently, the waste liquid receiving container at the bottom of the trough was removed, and a solid waste receiving container was placed below the trough. The staff opened the hinged door panel on one side of the auxiliary compartment 2, and used a shovel to shovel the compressed waste into the feed inlet on the other side. After the material fell, the rotating motor 3 was started and drove the crushing blade 4 at its output end to rotate at high speed. The crushing blade 4 used its spiral blade to cut and crush the compressed solid waste, so that the bulky plastic packaging bags, wood chips and other lightweight materials were shredded into small pieces, reducing the accumulation resistance of subsequent transportation, thereby achieving the effects of reducing volume, reducing humidity and facilitating subsequent collection and transfer.
