Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a novel waste recycling device for building engineering. Background Technology

[0002] During the construction process, a large amount of construction waste is often generated. When recycling this waste, recycling equipment is used to crush it. This equipment can crush large and irregularly shaped construction waste into smaller particles, which not only facilitates subsequent sorting, recycling, and reuse, but also effectively reduces the land area occupied by the waste and lowers transportation costs.

[0003] In daily work, it has been found that when existing construction waste recycling equipment crushes waste, dust falls off along with the crushed construction waste. A large amount of dust attached to the waste is also raised into the air. This dust spreads uncontrollably in all directions and quickly permeates the surrounding environment, easily polluting the environment. At the same time, it is not convenient to collect the flying dust, resulting in waste. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that dust overflows from the discharge port during crushing and feeding, polluting the environment and causing waste, and to propose a new type of waste recycling device for construction projects.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: A novel waste recycling device for construction projects includes a housing. Two crushing rollers are rotatably connected to the inner wall of the housing. Two motors are mounted on the surface of the housing, and the output ends of the motors are fixedly connected to one end of the crushing rollers. An auxiliary device is provided on the surface of the housing, including two suction heads fixedly connected to the inner wall of the housing. Supports are fixedly connected to both sides of the housing. Multiple sets of connecting pipes are fixedly connected to the surface of the suction heads. Multiple auxiliary cylinders are fixedly connected to the inner wall of the support. A filter assembly is provided between the connecting pipes and the auxiliary cylinders. An axial flow fan blade is rotatably connected to the inner wall of the auxiliary cylinder. A transmission assembly is provided between the crushing rollers and the axial flow fan blades. Through these components, when crushing and recycling waste, the crushing rollers drive the axial flow fan blades to rotate via the transmission assembly. The axial flow fan blades, in conjunction with the auxiliary cylinders, connecting cylinders, and suction heads, suck up dust to the filter assembly for filtration and collection.

[0006] Preferably, the transmission assembly includes a transmission rod rotatably connected to the support and the inner wall of the auxiliary cylinder. A belt is installed between the transmission rod and the crushing roller. Multiple bevel gears are fixedly connected to the surface of the transmission rod, and bevel gears are fixedly connected to the surface of the axial flow fan blade. The bevel gears mesh with each other. Through the above components, during transmission, the crushing roller rotates, and the crushing roller drives the transmission rod and bevel gears to rotate via the belt. The bevel gears drive the bevel gears and the axial flow fan blade to rotate, thereby achieving the transmission effect.

[0007] Preferably, the inner wall of the suction head is fixedly connected with an intercepting net. Through the above-mentioned components, the intercepting net can intercept broken impurities and reduce the amount entering the suction head.

[0008] Preferably, the filter assembly includes a filter element located between the connecting pipe and the auxiliary cylinder, a surface positioning ring for the filter element, and two threaded caps fitted on the surface of the filter element. Threaded ends are fixedly connected to the surfaces of both the connecting pipe and the auxiliary cylinder, and the threaded caps are threadedly connected to the threaded ends. Through the above components, the two threaded caps can be connected to the threaded ends on the surfaces of the connecting pipe and the auxiliary cylinder respectively, allowing the filter element to be installed and enabling it to intercept and collect dust.

[0009] Preferably, the filter element includes a cylinder and a filter bag, the filter bag being fixedly connected to the inner wall of the cylinder. Through the above components, the filter element intercepts and collects the filter bag during collection and filtration.

[0010] Preferably, sealing gaskets are fixedly connected to both ends of the cylinder.

[0011] Preferably, the surface of the threaded cap is fixedly connected with a protrusion, and there are multiple protrusions.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, by setting up an auxiliary device, the transmission link, axial flow fan blades, suction head, connecting pipe, auxiliary cylinder and filter assembly work together. During the waste crushing process, the rotation of the axial flow fan blades generates suction force, and the suction head promptly draws the dust generated during crushing to the filter assembly, effectively intercepting and collecting the dust, greatly reducing dust overflow, reducing pollution to the construction site and surrounding environment, and protecting the air environment and human health.

[0014] In this invention, by setting up a transmission component, the rotation of the crushing roller is converted into the power of the axial flow fan blades through the cooperation of a belt, a transmission rod, a first bevel gear, and a second bevel gear. This achieves efficient power transmission, eliminates the need for an additional power source, reduces energy consumption, lowers equipment operating costs, and improves overall recycling efficiency.

[0015] By setting up a filter assembly and using a threaded sleeve and threaded end connection, the filter element is installed between the connecting pipe and the auxiliary cylinder, making installation and disassembly very convenient, and the filter element can be quickly removed for cleaning or replacement.
