Description

[0001] This application is a divisional application of the application filed on August 19, 2024, with application number 202411135885.6 and invention name “A construction waste plastic separation device with gas separation”. Technical Field

[0002] The invention relates to the technical field of construction waste separation, and in particular to a construction waste plastic separation device. Background Art

[0003] To process construction waste, including plastics and hazardous waste, in order to better separate plastics, it is necessary to first crush the construction waste, and then screen and separate the plastics and construction waste.

[0004] However, at present, there is no special treatment for plastics and metals in the crushed construction waste, and there is no special equipment to separate plastics and metals. Plastics and metals need to be separated manually in the later stage. The construction waste will be mixed with water, making the construction waste damp, causing the construction waste to stick together after being crushed. The crushed construction waste is not dried, which affects the separation of plastics from other construction waste. When the crushed construction waste is separated, the plastic will precipitate with other construction waste, making the plastic separation efficiency low. A filter will be used for plastic separation, and the separation liquid and construction waste need to be separated into solid and liquid. The filter will be clogged during the solid-liquid separation, affecting the speed of solid-liquid separation. Summary of the invention

[0043] Beneficial Effects

[0044] According to the plastic separation device of each embodiment of the present invention, compared with the traditional separation device, its first blowing fan separates the crushed plastic from the construction waste by gas, thereby avoiding the accumulation of plastic and construction waste together. Through the cooperation of the first blowing fan and the electric heating wire, the first blowing fan dries the moisture in the garbage. When heated, the electric heating wire heats the airflow generated by the first blowing fan, thereby accelerating the drying speed of the moisture in the crushed garbage, solving the problem of damp construction waste causing the construction waste to stick together after being crushed. An iron block is arranged on the rotating disk, and the iron block absorbs and collects the metal in the construction waste. Separation liquid is added to the second shell to separate the plastic. The setting of the water outlet pipe has the effect of blowing the bottom of the separation liquid, so that the plastic mixed in the construction waste floats upward for separation.

[0045] In addition, a collecting drawer is clamped at the bottom of the second shell, and the collecting drawer collects the settled construction waste. The collecting drawer is convenient for cleaning the collected construction waste. The pressing seat is pressed by the pressing seat, and there is an inclined surface at the bottom of the pressing seat. The inclined surface enables the pressing seat to effectively press the collecting drawer when it is downward, thereby sealing the collecting drawer and the mounting hole of the second shell. There is a rotatably connected pushing bolt above the pressing seat. When the pushing bolt is rotated, the pressing seat will be driven to move, thereby facilitating the pressing and disassembly of the collecting drawer.

[0046] In addition, the water pipe has a conical hole with the large diameter facing upwards. There are ring-shaped diversion blocks on the inside of the conical hole. When the water pump pumps water, the separation liquid will flow outward through the conical hole at the bottom of the outlet pipe, thereby blowing the sinking construction waste. The diversion block makes the separation liquid flow outward in a rotating state, thereby making the impact force of the separation liquid stronger. The conical hole makes the separation liquid diffuse outward, thereby increasing the contact area with the construction waste, allowing the plastic mixed in the construction waste to float upward better.

[0047] In addition, a magnet is clamped on the inner side of the first shell, and three fan-shaped magnets are clamped on the rotating disk. When the iron block contacts the magnet, the iron block has magnetism, so that the iron block absorbs the metal in the construction waste, and the rotating disk isolates the iron block. When the iron block rotates to the outside of the magnet, the magnetism of the iron block is eliminated, so that the metal adhered to the iron block falls off downward, and the fallen metal moves outward through the third funnel for collection.

[0048] In addition, there is an extrusion cam between the water pump and the drive motor, and there are two connecting sleeves on the outside of the extrusion cam. The connecting sleeves act as a coupling, so that the drive motor can effectively drive the water pump to pump water. The drive motor drives the extrusion cam and the drive motor to rotate, so that the drive motor can effectively drive the water pump to pump water.

[0049] In addition, there is a connecting plate and a cleaning brush on one side of the sliding rod, and the extrusion cam squeezes the sliding rod. There is an elastic part on the outside of the sliding rod, and the elastic part pushes the sliding rod to reset. When the connecting plate moves back and forth, it drives the cleaning brush to move back and forth to sweep the surface of the filter, thereby achieving the effect of preventing the filter from being blocked.

The guide bevel makes the separation liquid flow outward in a rotating state, thereby making the impact force of the separation liquid stronger. The conical hole makes the separation liquid diffuse outward. Thereby, the contact surface with the construction waste is increased, so that the plastic mixed in the construction waste can float upward better. When the rotating shaft 501 rotates, it drives the rotating disk 502 to rotate. A magnet is clamped on the inner side of the first shell 1. The magnet and the iron block of the rotating disk 502 are relatively positive. When the iron block contacts the magnet, the iron block has magnetism, so that the iron block can absorb the metal in the construction waste. When the iron block rotates to the outside of the magnet, the magnetism of the iron block is eliminated, so that the metal adhered to the iron block falls off downward, and the fallen metal moves outward through the second funnel 102 for collection.

[0084] Finally, it should be noted that when describing the position of each component and the matching relationship between them, the present invention usually takes one / a pair of components as an example. However, those skilled in the art should understand that such position, matching relationship, etc. are also applicable to other components / other pairs of components.

[0085] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the protection scope of the present invention. The protection scope of the present invention is determined by the appended claims.
