Description

Technical Field

[0001] This utility model belongs to the field of waste treatment equipment, and in particular relates to a sorting device for construction and decoration waste. Background Technology

[0002] With the acceleration of industrialization and urbanization, the construction industry has also developed rapidly. Building decoration is a common activity, used to beautify interior environments, enhance functionality, or repair damage. However, one of the problems that arises with decoration is the generation of construction waste. The disposal of construction waste has always been a major concern. How to effectively dispose of construction waste to reduce environmental pollution and achieve resource reuse is a problem we need to seriously consider and solve. Generally speaking, construction waste mainly includes waste materials and other waste generated during the construction process. When disposing of construction waste, we need to follow the principles of "reduction, resource recovery, and harmlessness." Specifically, here are some solutions for construction waste disposal: First, for recyclable materials, we should sort and recycle them as much as possible. Construction waste generally consists of red bricks, sand, concrete blocks, and a large amount of dust. It is not easily combustible, has low toxicity, and can be used for backfilling. Renovation waste consists of leftover materials from renovations, some of which are toxic. It requires multiple crushing and sorting processes. Sorting is generally done manually, while crushing is done using existing crushers. The process is complex, time-consuming, labor-intensive, inefficient, and also poses environmental pollution problems due to its cumbersome procedures and low efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a device that can be used for crushing and sorting construction and decoration waste, which can remove some construction and decoration waste that is not easy to crush, and sort out the construction and decoration waste that is easier to crush for crushing and recycling.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1-4 As shown. A construction and renovation waste sorting device includes a box body 1, a cover plate 5 on the top of the box body 1, a feed inlet 2 in the middle of the cover plate 5, a frame on the box body 1 at the feed inlet 2, a crushing motor 3 on the frame, a crushing chamber 6 below the feed inlet 2, a rotating shaft 4 coaxially and fixedly connected to the output shaft of the crushing motor 3, the rotating shaft 4 extending to the crushing chamber 6, a plurality of crushers 8 evenly distributed on the rotating shaft 4, a plurality of resistance columns 7 on the inner wall of the crushing chamber 6, a sorting bin 10 below the crushing chamber 6 and communicating with it, a conical sorting net 11 inside the sorting bin 10, a debris outlet 12 on the bottom edge of the sorting bin 10 on the box body 1, a pulverizing bin 13 inside the box body 1 below the conical sorting net 11, a pulverizing bin 13 containing pulverizing steel balls 14, a screen 15 at the bottom of the pulverizing bin 13, fine material outlets 16 on both sides of the bottom of the screen 15, a pulverizing motor 17 below the pulverizing bin 13, and a pulverizing motor 17 coaxially and fixedly connected to the pulverizing bin 13. The crushing motor 17 can be fixed to the housing 1. Inside the housing 1, limit wheels 22 are set on both sides of the crushing chamber 13. The limit wheels 22 are connected to the housing 1 through wheel frames and make rolling contact with the crushing chamber 13. A bearing mounting seat 23 is set at the bottom of the housing 1. A thrust bearing 24 is set on the bearing mounting seat 23. The thrust bearing 24 supports the crushing chamber 13. The output shaft of the crushing motor 17 passes through the bearing mounting seat 23 and the thrust bearing 24 and is connected to the crushing chamber 13.

[0021] In use, construction and renovation waste (including thin steel bars, bolts, wood, concrete blocks, etc.) is fed into the box 1 through the feed inlet 2. When the waste passes through the crushing chamber 6, the crushing motor 3 drives the crusher 8 to rotate. Under the impact of the crusher 8 and with the help of the resistance column 7, the more easily broken concrete is crushed, while steel bars, bolts, etc., which are harder, are not easily crushed. Wood, due to its light weight, will only crack even if it is impacted, but will not be crushed. Therefore, steel bars, bolts, wood, etc. can be screened by the conical sorting screen 11 and discharged from the debris outlet 12. After the concrete is crushed, it can fall into the crushing chamber 13 through the conical sorting screen 11. When the crushing motor 17 drives the crushing chamber to rotate, the crushing steel balls 14 inside rub and collide with the concrete, further crushing the concrete. The crushed concrete powder is discharged from the fine material outlet 16 after passing through the screen. If the material discharged from the debris outlet 12 contains concrete, it can be recycled.

[0022] A crushing head 9 is installed on the end face of the crusher 8. The hardness of the crushing head 9 reaches 40HRC-60HRC. The crushing head is hinged to the crusher body by a pin, which can protect the crushing head 9 and prevent it from breaking due to excessive impact force.

[0023] The frame 18 is a crossbeam, with both ends of the crossbeam fixed to the inner wall of the feed inlet 2, for the installation of the crushing motor 3. The casing of the crushing motor 3 can be fixed to the frame without affecting the function of the feed inlet 2.

[0024] The conical sorting net 11 has a throughput of 50mm to 100mm. The conical sorting net 11 includes a conical frame 19 and a screen 20 fixed on the conical frame 19. The conical frame 19 is fixed to the box body 1 and is used to support the screen 20.

[0025] A support 21 is provided at the bottom of the crushing chamber 13. The support 21 is fixed to the side wall of the crushing chamber 13, and the screen 15 is fixed on the support 21. The support 21 is used to support the screen 15.

[0026] The size of the crushing steel balls 14 is 10mm-30mm, and the rotation speed of the crushing chamber is 80-200r / min.

[0027] The above are merely preferred embodiments of this utility model.
