Technical Field

[0001] This utility model pertains to waste treatment equipment, specifically to a high-efficiency crushing and shaping integrated machine for building aggregates. Background Technology

[0002] In the past, most of my country's construction waste, decoration waste, and household waste were transported by construction companies to the suburbs or rural areas without any treatment, and were dumped or buried in the open, consuming a lot of land. At the same time, the spillage and dust and sand flying during the transportation and dumping process caused serious environmental pollution.

[0003] To improve arable land utilization and reduce environmental pollution, these accumulated wastes now need to be cleaned up and recycled. This accumulated waste includes various types of construction and decoration waste, household waste, etc. However, it is difficult to completely separate materials such as plastic bags, plastic sheets, cardboard boxes, old clothes and fabrics, thin steel bars, aluminum alloy strips, sponges, foam, asbestos cloth, asbestos boards, and weeds beforehand, and the labor intensity of the separation process is also very high. These materials must first be separated and sorted before undergoing subsequent recycling processes to obtain high-quality, high-purity recycled materials from construction and decoration waste. Therefore, various accumulated waste separation equipment has emerged. Generally, a waste shearing machine is used first for separation, followed by classification and sorting. Summary of the Invention

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0023] The following is in conjunction with the appendix Figures 1-2 The structure and working process of this utility model will be described in detail.

[0024] A waste shearing and air separation integrated machine includes a waste shearing machine and a horizontal air separator 6 installed below the waste shearing machine, which can effectively improve the utilization efficiency of the equipment. The horizontal air separator includes an air separator casing, with an air inlet pipe and air nozzles 9 at the front end of the air separator casing. A separation roller 10 is installed at the front end of the air separator casing, located below and behind the discharge port of the waste shearing machine. The air nozzles are located between the discharge port of the waste shearing machine and the separation roller, with the air blowing direction directly facing the line connecting the discharge port of the waste shearing machine and the separation roller. A collection hopper 11 is installed at the bottom of the air separator casing, and a return air pipe 12 is installed at the top rear end of the dust collection chamber of the air separator. The return air pipe is connected to the air inlet pipe to form a circulating air duct. The air power is recycled, which is beneficial to environmental protection.

[0025] The integrated shearing and air separation machine for aged waste described in this utility model has several grid nets 7 set at the top of the dust collection chamber of the air separator behind the separating roller. Each grid net corresponds to a primary collection hopper, that is, the corresponding collection hopper is also equipped with several primary collection hoppers.

[0026] The integrated shearing and air separation machine for aged waste described in this utility model features an inclined grid mesh. The mesh size decreases progressively from the separating roller towards the return air duct. The main function of the grid mesh is to effectively block various materials blown into the dust collection chamber of the air separator, allowing materials of different densities to settle to the lower collection hopper by their own weight. Simultaneously, the grid mesh also prevents large, lightweight particles from entering the return air duct and clogging the circulating air duct.

[0027] The integrated shearing and air-separation machine for aged waste of this utility model includes a casing, a shearing rotor 5 installed inside the casing, a distribution cone 1 at the top of the shearing rotor, a shearing blade fixing plate 2 installed on the shearing rotor, and shearing blades 4 installed on the shearing blade fixing plate. An inclined discharge bottom plate is installed at the bottom of the shearing rotor, and the discharge bottom plate and the outlet on the side wall of the shearing casing form a discharge port, with the front end of the air separator directly corresponding to the discharge port. This waste shearing machine uses a vertical rotor with wear-resistant shearing blades made of high-speed steel installed on the rotor. The high-speed rotation of the shearing rotor is driven by a motor, which first shears and crushes various plastic bags, plastic sheets, cardboard boxes, old clothes and fabrics, thin steel bars, aluminum alloy thin strips, sponges, foam, asbestos cloth, asbestos boards, weeds, and other materials in the aged waste to be separated, so as to facilitate the subsequent separation of materials of different specific gravities by the action of air force after the materials enter the horizontal air separator.

[0028] This utility model of a shearing machine for aged waste adopts a grate-type structure made of wear-resistant steel for the bottom unloading plate, allowing heavy materials in the aged waste to fall directly into the heavy material collection hopper through the grate. At the same time, some of the heavy materials blown onto the dispersing and separating rollers also fall into the heavy material collection hopper by gravity.

[0029] The integrated shearing and air separation machine for aged waste described in this utility model has a shearing blade fixed to a shearing blade fixing plate by shearing blade fixing bolts 3, which can be quickly replaced by a simple method of disassembly and assembly using fixing bolts.

[0030] The integrated shearing and air-separating machine for aged waste described in this utility model has the waste shearing machine mounted on a skid-mounted support base 8, and the horizontal air-separating machine mounted on an air-separating machine support. It can be moved short distances depending on the working area to reduce dust pollution caused by varying feeding distances of the aged waste.

[0031] Furthermore, both the integrated skid-mounted support base and the air separator support are adjustable. The adjustable structure consists of an upper component and a lower component. Multiple adjustment holes are vertically arranged on either the upper or lower component, and corresponding adjustment mounting holes are provided on the lower or upper component. Adjustment bolts pass through the adjustment mounting holes and adjustment holes to fix the upper component to the lower component. The height can be adjusted according to actual working conditions.

[0032] The working process of this utility model is as follows:

[0033] First, various plastic bags, plastic sheets, cardboard boxes, old clothes and fabrics, thin steel bars, aluminum alloy strips, sponges, foam, asbestos cloth, asbestos boards, weeds, and other materials from the aged waste to be separated are fed into the waste shearing machine. A motor drives the high-speed rotation of the shearing machine rotor, which in turn drives the wear-resistant shearing blades mounted on the rotor to shear and shred the materials. Then, strong air from the nozzle 9 of the horizontal air separator blows the shredded mixture from the waste shearing machine toward the outer cylinder of the separating roller. Heavier materials fall into the heavy material collection hopper due to gravity, while lighter materials move behind the separating roller under the influence of the strong airflow, and are then blocked by each and every fence mesh, thus separating materials of different weights. Finally, all materials settle into their corresponding collection hoppers in the horizontal air separator.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
