Description

Technical Field

[0001] This utility model relates to the field of waste recycling, and more specifically, to a waste recycling device for prefabricated component production. Background Technology

[0002] The production of precast components generates a large amount of waste, which mainly includes concrete fragments, steel remnants, and other auxiliary materials. Traditionally, this waste is often regarded as waste and directly discarded or landfilled, which not only wastes resources but may also have a negative impact on the environment.

[0003] A search revealed that Chinese Patent Publication No. CN220027258U discloses "a construction site waste recycling device, which uses an empty trough, a second motor, a shaft, a rotating wheel, a screening plate, a chute, a sliding plate, and a collection box to make the screening plate shake and screen, thereby facilitating rapid screening of construction waste, improving the stability of the device during operation, extending its service life, and enhancing its practicality. This avoids slow screening of construction waste, which reduces the device's screening efficiency, and also prevents uneven material size and poor recycling quality during subsequent recycling." However, the following drawbacks still exist:

[0004] (1) In actual use, the recycled waste was not directly crushed, resulting in the particle size requirement for reuse not being met after recycling.

[0005] (2) In actual use, it is impossible to screen and classify the metal waste in the prefabricated component waste, which will lead to waste of resources.

[0006] Therefore, we have made improvements to this by proposing a waste recycling device for prefabricated component production. Utility Model Content

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] like Figure 1-5 As shown, this embodiment proposes a waste recycling device for prefabricated component production, including a shell 1, a crushing component 2 is provided on the top of the shell 1, a conveying and screening component 3 is provided on the crushing component 2, and a sorting component 4 is installed on the conveying and screening component 3.

[0035] like Figure 3 As shown, the crushing assembly 2 includes a recycling bin 201, a jaw crusher 202, a support plate 203, and a first conveyor belt 204. The recycling bin 201 is located inside the housing 1. The jaw crusher 202 is installed on the top of the housing 1. The support plate 203 is fixedly installed on one side of the jaw crusher 202. One end of the first conveyor belt 204 is installed on the jaw crusher 202, and the other end is installed on the support plate 203. In use, the precast component waste to be recycled is placed on the first conveyor belt 204. The first conveyor belt 204 and the jaw crusher 202 are started so that the waste is evenly transported into the jaw crusher 202 for crushing, which facilitates subsequent recycling and reuse.

[0036] like Figure 3 and Figure 4 As shown, the conveying and screening assembly 3 includes a second conveyor belt 301, a screen 302, an extension plate 303, a motor 304, and an eccentric wheel 305. The second conveyor belt 301 is installed inside the recovery bin 201 and located below the jaw crusher 202. The screen 302 is inclined, with its lower end hinged to the inside of the recovery bin 201 and its higher end located below the material discharge end of the second conveyor belt 301. The extension plate 303 is fixedly connected to the inside of the recovery bin 201. The motor 304 is installed on one side of the extension plate 303, and the eccentric wheel 305 is fixedly connected to the motor 304. At the output end, the other end of the screen 302, away from the hinge end, is movably connected to the eccentric wheel 305. During use, the crushed sand and gravel particles will fall onto the second conveyor belt 301 through the discharge end of the jaw crusher 202 for transportation. The motor 304 is started, driving the eccentric wheel 305 to rotate. After the eccentric wheel 305 rotates, the protruding end will hit the screen 302, causing the screen 302 to shake. The sand and gravel particles are transported onto the screen 302 through the second conveyor belt 301. The screen 302 shakes and separates sand and gravel particles of different sizes for subsequent reuse.

[0037] like Figure 3 As shown, the sorting component 4 includes a magnetic layer 401, a scraper 402, and a third conveyor belt 403. The magnetic layer 401 is disposed on the second conveyor belt 301. The scraper 402 is fixedly connected to the inside of the recycling bin 201 and works in conjunction with the magnetic layer 401. The third conveyor belt 403 is disposed inside the recycling bin 201 and located below the scraper 402. The third conveyor belt 403 and the screen 302 are respectively located at both ends of the length direction of the second conveyor belt 301. The scraper 402 is located between the second conveyor belt 301 and the third conveyor belt 403. The top of the 02 contacts the magnetic layer 401 on the lower surface of the second conveyor belt 301 to scrape off the adsorbed material on the magnetic layer 401. The bottom has a gap between it and the upper surface of the third conveyor belt 403 to allow the scraped material to pass through. When sand and gravel particles are transported on the second conveyor belt 301, metal particles contained in the sand and gravel particles will be adsorbed by the magnetic layer 401, so that the metal particles will not enter the screen 302. They will be scraped off by the scraper 402 and fall onto the third conveyor belt 403 for separation from the sand and gravel particles, which is convenient for subsequent recycling.

[0038] like Figure 1 As shown, a feed hopper 5 is fixedly installed on the top of the jaw crusher 202. The feed hopper 5 is in the shape of an inverted trapezoid. When in use, the feed hopper 5 can provide protection when the jaw crusher 202 crushes the waste material to prevent stones from flying.

[0039] like Figure 3As shown, a guide plate 6 is fixedly connected inside the recycling bin 201 for use in guiding material through the screen 302. One end of the guide plate 6 is located below the lower end of the screen 302 to receive the unloaded material from the screen 302. A receiving plate 7 is fixedly connected inside the recycling bin 201 and is located below the screen 302. Both the guide plate 6 and the receiving plate 7 extend to the outside of the recycling bin 201. In use, the guide plate 6 can guide the large sand and gravel particles screened out by the screen 302 to discharge, and the receiving plate 7 can guide the small sand and gravel particles screened out by the screen 302 to discharge. The guide plate 6 and the receiving plate 7 are connected to an external storage device to separate and store sand and gravel particles of different sizes.

[0040] like Figure 3 As shown, the recycling bin 201 is equipped with a guide plate 8 for guiding the third conveyor belt 403. The guide plate 8 is located below the third conveyor belt 403. When in use, the guide plate 8 can guide the metal particles transported on the third conveyor belt 403 to discharge.

[0041] like Figure 5 As shown, the discharge end of the jaw crusher 202 is equipped with a discharge cylinder 9 for centralized discharge. The discharge cylinder 9 is Y-shaped. During use, the discharge cylinder 9 can centrally discharge the particles crushed by the jaw crusher 202, prevent particles from splashing, and improve discharge stability.

[0042] Specifically, when using this precast component production waste recycling device: the precast component waste to be recycled is placed on the first conveyor belt 204, and the first conveyor belt 204 and jaw crusher 202 are started, so that the waste is evenly transported into the jaw crusher 202 for crushing, which facilitates subsequent recycling and reuse. Then, the crushed sand and gravel particles will fall onto the second conveyor belt 301 through the discharge end of the jaw crusher 202 for transportation. The motor 304 is started, driving the eccentric wheel 305 to rotate. After the eccentric wheel 305 rotates, the protruding end will strike... The screen 302 is shaken, and the sand and gravel particles are transported onto the screen 302 by the second conveyor belt 301. The screen 302 shakes and separates the sand and gravel particles of different sizes, which is convenient for subsequent recycling. When the sand and gravel particles are transported on the second conveyor belt 301, the metal particles contained in the sand and gravel particles will be attracted by the magnetic layer 401, so that the metal particles will not enter the screen 302. They will be scraped off by the scraper 402 and fall onto the third conveyor belt 403 for separation from the sand and gravel particles, which is convenient for subsequent recycling.

[0043] All technical features in this embodiment can be freely combined according to actual needs.

[0044] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
