Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical engineering and automation technology, and in particular to a construction waste recycling device with a multi-layer screening structure. Background Technology
[0002] In the resource recovery process, traditional technologies mainly rely on the physical properties of materials (such as size and density) for single classification. This approach has obvious drawbacks: on the one hand, traditional screening devices can usually only separate specific materials and it is difficult to achieve multi-component collaborative sorting; on the other hand, due to the complex composition and large size differences of construction waste, existing equipment generally suffers from low sorting efficiency, resulting in insufficient purity of renewable aggregates, which seriously affects the subsequent resource recovery effect.
[0003] Therefore, there is a particular need for a construction waste recycling device with a multi-layer screening structure to solve the above problems. Utility Model Content
[0004] In order to overcome the shortcomings of traditional construction waste treatment methods, such as low sorting efficiency, difficulty in achieving multi-component collaborative sorting, and insufficient resource utilization rate, which result in insufficient purity of renewable aggregates and seriously affect the subsequent utilization effect, this utility model provides a construction waste recycling device with a multi-layer screening structure.
[0005] This utility model is achieved through the following technical means: a construction waste recycling device with a multi-layer screening structure, including a first shell, a second shell, support feet, a fixing plate, elastic elements, filter plates, a vibration generator, a discharge plate, and a cleaning mechanism. The second shell is fixedly connected to the outer right side wall of the first shell. The bottom of the first shell and the bottom of the second shell are both fixedly connected with symmetrical support feet. Multiple longitudinally arranged fixing plates are fixedly connected to the inner side wall of the first shell. Symmetrical elastic elements are fixedly connected to the top of the fixing plates. Filter plates are fixedly connected to the other ends of each of the four corresponding elastic elements. The filter plates are all obliquely arranged, and the oblique directions are alternately opposite. The aperture of the filter plates decreases from top to bottom. Symmetrical vibration generators are fixedly connected to the bottom of the filter plates. Three discharge plates are fixedly connected to the first shell. Two discharge plates correspond to the front side of the upper filter plate and the front side of the lower filter plate, respectively. The other discharge plate corresponds to the rear side of the middle filter plate. A cleaning mechanism is provided on the upper filter plate and the middle filter plate.
[0006] Furthermore, the cleaning mechanism includes a sliding sleeve, a scraper, a connecting plate, and a hydraulic cylinder. The upper filter plate and the middle filter plate are both fitted with sliding sleeves in a horizontal array. A scraper is fixed between the inner walls of two adjacent sliding sleeves on opposite sides. Scrapers are also fixed between the leftmost sliding sleeve and the filter plate and between the rightmost sliding sleeve and the filter plate. A connecting plate is fixed between the bottom of the sliding sleeve of the upper filter plate and the bottom of the scraper. A connecting plate is also fixed between the bottom of the sliding sleeve of the middle filter plate and the bottom of the scraper. Two hydraulic cylinders are fixed inside the second housing, and the connecting plate is fixed to the piston rod of the hydraulic cylinder.
[0007] Furthermore, it also includes inclined blocks, with symmetrical inclined blocks fixed to the top of the filter plate.
[0008] Furthermore, it also includes a drain pipe, which is fixed to the rear bottom side of the first housing.
[0009] Furthermore, the first outer shell is provided with a viewing window.
[0010] Furthermore, the bottom of the support feet is equipped with anti-slip pads.
[0011] As can be seen from the above description of the structure of this utility model, the design starting point, concept and advantages of this utility model are: 1. This utility model uses a three-layer filter plate structure with different pore sizes, combined with a vibration generator, to achieve precise grading of construction waste, solving the problems of low sorting efficiency, difficulty in achieving multi-component collaborative sorting, and insufficient resource utilization rate in traditional construction waste treatment methods, resulting in insufficient purity of renewable aggregates and seriously affecting the subsequent utilization effect.
[0012] 2. This utility model ensures uniform material distribution and avoids uneven loading on the screen surface by incorporating inclined blocks.
[0013] 3. This utility model uses a hydraulic cylinder to drive the sliding sleeve and scraper to remove filter plate blockage in real time, reducing the frequency of manual cleaning and lowering maintenance costs. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] Example: A construction waste recycling device with a multi-layer screening structure, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the device includes a first outer shell 1, a second outer shell 101, support feet 102, fixing plates 2, elastic elements 3, filter plates 4, a vibration generator 5, an inclined block 6, a discharge plate 7, a drain pipe 8, and a cleaning mechanism. The first outer shell 1 has a viewing window for easy observation of the internal screening process. The second outer shell 101 is welded to the outer right side wall of the first outer shell 1. The bottom of both the first outer shell 1 and the bottom of the second outer shell 101 are bolted to symmetrically arranged support feet 102. The bottom of the support feet 102 is equipped with anti-slip pads to improve the stability of the equipment. Multiple longitudinally arranged fixing plates 2 are welded to the inner side wall of the first outer shell 1. Symmetrically arranged elastic elements 3 are bonded to the top of the fixing plates 2. Filter plates 4 are bonded to the other ends of each pair of four corresponding elastic elements 3. The filter plates 4 are all obliquely arranged. The filter plates 4 have alternating opposite inclination directions, and the aperture of the filter plates 4 decreases from top to bottom to achieve multi-stage screening. The bottom of the filter plates 4 is bolted with symmetrical vibration generators 5 to drive the filter plates 4 to vibrate and improve screening efficiency. The top of the filter plates 4 is welded with symmetrical inclined blocks 6 to guide the material to be evenly distributed and improve the screening effect. The first outer shell 1 is bolted with three discharge plates 7. Two discharge plates 7 correspond to the front side of the upper filter plate 4 and the front side of the lower filter plate 4, respectively, and the other discharge plate 7 corresponds to the rear side of the middle filter plate 4, so as to classify and discharge construction waste of different particle sizes. The bottom rear side of the first outer shell 1 is welded with a drain pipe 8 to discharge any sewage or fine particles that may accumulate. The upper filter plate 4 and the middle filter plate 4 are equipped with cleaning mechanisms.
[0023] like Figures 1-5As shown, the cleaning mechanism includes a sliding sleeve 9, a scraper 10, a connecting plate 11, and a hydraulic cylinder 12. Both the upper filter plate 4 and the middle filter plate 4 are fitted with sliding sleeves 9 arranged in a horizontal array. A scraper 10 is welded between the inner walls of two adjacent sliding sleeves 9 on opposite sides. Scrapers 10 are also welded between the leftmost sliding sleeve 9 and the filter plate 4 and between the rightmost sliding sleeve 9 and the filter plate 4 to ensure the cleaning of the screen. A connecting plate 11 is welded between the bottom of the sliding sleeve 9 of the upper filter plate 4 and the bottom of the scraper 10. A connecting plate 11 is also welded between the bottom of the sliding sleeve 9 of the middle filter plate 4 and the bottom of the scraper 10. Two hydraulic cylinders 12 are bolted inside the second outer casing 101, and the connecting plate 11 is fixed to the piston rod of the hydraulic cylinder 12.
[0024] First, place the equipment on a level surface, ensuring the stability of the overall structure consisting of support feet 102, the first outer shell 1, and the second outer shell 101. Then, allow construction waste to enter the first outer shell 1 from above, allowing it to fall onto the top filter plate 4. Inclined blocks 6 guide the waste to distribute it evenly, preventing localized accumulation. Start the vibration generator 5, causing each layer of filter plates 4 to vibrate at high frequency. The elastic element 3 provides cushioning. Because the pore size of the filter plates 4 decreases from top to bottom, the construction waste is graded and screened under vibration. The largest particles remain on the upper filter plate 4, medium-sized particles fall into the middle filter plate 4, and the smallest particles... Materials falling into the bottom filter plate 4 are discharged through the corresponding discharge plates 7 according to their different sizes. Large particles in the upper layer are discharged from the front upper discharge plate 7, medium particles in the middle layer are discharged from the rear discharge plate 7, and fine particles in the lower layer are discharged from the front lower discharge plate 7. Fine particles and wastewater generated during the screening process are discharged through the drain pipe 8. When the filter plate 4 becomes clogged, the hydraulic cylinder 12 is activated. The piston rod of the hydraulic cylinder 12 drives the connecting plate 11, which in turn drives the sliding sleeve 9 and the scraper 10 to reciprocate along the surface of the filter plate 4 to remove the construction waste clogging the filter plate 4 and ensure screening efficiency. After screening, the vibration generator 5 and the hydraulic cylinder 12 are turned off.
[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
