Description

Technical Field

[0001] This utility model relates to the field of mineral processing technology, specifically a novel structure for improving the wear resistance of the side pressure plate of a vibrating screen. Background Technology

[0002] Mineral processing is a part of mineral processing, the main purpose of which is to separate valuable minerals from collected ore and remove useless or harmful impurities. A banana-shaped vibrating screen is a specially designed vibrating screening device, named for its banana-like screen surface. It is mainly used in mining, coal, metallurgy, and chemical industries for classifying and screening particulate materials.

[0003] As the core screening equipment in the three-stage closed-circuit process of the mineral processing plant, the banana vibrating screen has potential structural failure risks during operation. Its side pressure plate adopts a composite structure design of steel frame and polyurethane, which theoretically can effectively suppress screen vibration displacement through elastic support. However, in actual working conditions, due to the thick layer of screened material and frequent impact loads, the traditional fastening clamps wear out severely under high-frequency alternating loads (average daily wear reaches 0.2-0.5mm). At the same time, the wear resistance of the polyurethane side pressure plate is insufficient, leading to frequent screen plate fixation failures. Such failures not only cause continuous interruption of medium and fine crushing operations (average single downtime of 1 hour), but also cause abnormal wear of the screen side (annual wear depth reaches 1.5-2mm), significantly shortening the service life of the equipment. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a novel structure for improving the wear resistance of the side pressure plate of a vibrating screen, so as to solve the problem of easy wear of the side pressure plate of a banana vibrating screen mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel structure for improving the wear resistance of the side pressure plate of a vibrating screen, comprising a high-strength steel frame, wherein an inner wear-resistant layer is provided on one side of the high-strength steel frame, and an outer wear-resistant component is provided on one side of the inner wear-resistant layer.

[0006] The outer wear-resistant component includes a wear-resistant rubber pad disposed on one side of the inner wear-resistant layer, and a protective protrusion is fixedly connected to one side of the wear-resistant rubber pad.

[0007] Preferably, threaded holes are provided on the high-strength steel frame, the inner wear-resistant layer, and the wear-resistant rubber pad, and first countersunk bolts are connected to the threaded holes of the high-strength steel frame and the inner wear-resistant layer.

[0008] Preferably, the wear-resistant rubber pad has a threaded hole on one end and a groove on one side. A rod is inserted into the groove, and the groove communicates with the threaded hole. A third countersunk bolt is threadedly connected to one end of the wear-resistant rubber pad.

[0009] Preferably, the wear-resistant rubber pad and the inner wear-resistant layer are detachable structures, and the protective protrusion has a trapezoidal structure when viewed from the side.

[0010] Preferably, a second countersunk bolt is threaded onto one side of the wear-resistant rubber pad, and one end of the second countersunk bolt is connected to the inner wear-resistant layer.

[0011] Preferably, multiple sets of the protective protrusions and inserts are provided, and the multiple sets of protective protrusions and inserts are provided on the bottom side of the wear-resistant rubber pad.

[0012] Preferably, the protective protrusions and the inserts are distributed longitudinally at equal intervals on one side of the wear-resistant rubber pad.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This device improves wear resistance, thereby increasing service life and reducing maintenance costs.

[0015] (2) This device uses an inner wear-resistant layer on the outer wall of a high-strength steel frame as the basis for wear resistance. At the same time, a replaceable low-cost wear-resistant rubber pad is set on the outside of the inner wear-resistant layer. This not only improves the wear resistance of the device but also facilitates maintenance and reduces maintenance costs.

[0016] (3) This device sets protective protrusions longitudinally on the bottom side of the wear-resistant rubber pad. The protective protrusions are located at the lower end and are closer to the conveyed material. This not only improves the wear resistance of the lower end, but also disperses and guides the impacting material, thus avoiding severe wear on one part of the wear-resistant rubber pad surface.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3This utility model provides a technical solution: a novel structure for improving the wear resistance of the side pressure plate of a vibrating screen, comprising a high-strength steel frame 1, an inner wear-resistant layer 3 on one side of the high-strength steel frame 1, threaded holes on the high-strength steel frame 1, the inner wear-resistant layer 3, and the wear-resistant rubber pad 41, and first countersunk bolts 2 connected to the threaded holes of the high-strength steel frame 1 and the inner wear-resistant layer 3. The first countersunk bolts 2 of this structure can fix the high-strength steel frame 1 and the inner wear-resistant layer 3 to the side wall of the banana vibrating screen. The inner wear-resistant layer 3 is fused and fixed to the high-strength steel frame 1 after heating. An outer wear-resistant component 4 is provided on one side of the inner wear-resistant layer 3. The high-strength steel frame 1 ensures the compressive strength of the foundation of this device, preventing wear. The device exhibits severe deformation after being impacted by materials. The inner wear-resistant layer 3 is made of polyurethane elastomer. The inner wear-resistant layer 3 ensures the wear resistance of the device's foundation. The outer wear-resistant component 4 includes a wear-resistant rubber pad 41 disposed on one side of the inner wear-resistant layer 3. The wear-resistant rubber pad 41 has a threaded hole on one end and a groove on one side. A rod 45 is inserted into the groove, which communicates with the threaded hole. A third countersunk bolt 44 is threadedly connected to one end of the rod 45 and the wear-resistant rubber pad 41. This structure uses the third countersunk bolt 44 to fix the rod 45 to the wear-resistant rubber pad 41. The rod 45 is fixed from both the front and rear ends of the wear-resistant rubber pad 41. The wear-resistant rubber pad 41 and the inner wear-resistant layer 3 are designed to withstand severe deformation. The wear-resistant layer 3 is a detachable structure. The protective protrusion 43 has a trapezoidal structure when viewed from the side. This protective protrusion 43 is made of ceramic material, which makes it more wear-resistant. By placing the protective protrusion 43 on the bottom side of the wear-resistant rubber pad 41, it can protect the area on the bottom side of the wear-resistant rubber pad 41 that is more susceptible to material impact. A second countersunk bolt 42 is threadedly connected to one side of the wear-resistant rubber pad 41. One end of the second countersunk bolt 42 is connected to the inner wear-resistant layer 3. This structure can fix the wear-resistant rubber pad 41 to the inner wear-resistant layer 3 through the second countersunk bolt 42. Therefore, the wear-resistant rubber pad 41 can be disassembled and replaced for easy maintenance. The wear-resistant rubber pad 41 is made of ordinary wear-resistant rubber, such as nitrile rubber. Both the protective protrusions 43 and the insert rods 45 are longitudinally and evenly distributed on one side of the wear-resistant rubber pad 41. Multiple sets of protective protrusions 43 and insert rods 45 are provided, and multiple sets of protective protrusions 43 and insert rods 45 are set on the bottom side of the wear-resistant rubber pad 41. This structure can also disperse the material during the impact of the material through the protective protrusions 43, causing the material to rotate to the bottom and sides, thereby making the wear more uniform. The protective protrusions 43 are fixedly connected to one side of the wear-resistant rubber pad 41. During use, this device is installed on the side wall of the banana vibrating screen through the first countersunk bolt 2. During the production process, the size of this device can be made into a modular standard size of 1200*250*30mm, which can realize the standardization of spare parts.

[0023] Working principle: When using this new structure to improve the wear resistance of the side pressure plate of the vibrating screen, firstly, use the first countersunk bolt 2 to install the inner wear-resistant layer 3 and the high-strength steel frame 1 on the side wall of the banana vibrating screen. After installation, use the second countersunk bolt 42 to install the wear-resistant rubber pad 41 onto the outer wall of the inner wear-resistant layer 3. If the wear-resistant rubber pad 41 is severely worn during the use of this device, the second countersunk bolt 42 can be removed and the entire wear-resistant rubber pad 41 can be replaced. If the protective protrusion 43 on the outer wall of the wear-resistant rubber pad 41 is worn, the third countersunk bolt 44 at both ends of the wear-resistant rubber pad 41 can be removed, and then the corresponding protective protrusion 43 and the insert rod 45 can be removed and replaced.

[0024] Although the present invention 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 invention should be included within the protection scope of the present invention.
