Description

Technical Field

[0001] This utility model relates to the field of slag dewatering technology, and in particular to a vibrating feeder dewatering screen for slag. Background Technology

[0002] The slag from municipal solid waste incineration contains various materials such as metals, plastics, and soil. These materials can be screened to maximize their utilization. When recovering useful materials from the slag, large amounts of water are sometimes used to treat it. To facilitate the transportation and storage of the treated slag, dewatering is necessary. Therefore, vibrating dewatering screens are frequently used in the slag screening process.

[0003] The existing vibrating feeder dewatering screen for slag typically uses springs to connect the four corners of the screen to the four corners of the frame. However, the performance of these springs deteriorates over time. When the slag to be dewatered has a high moisture content, it is heavy and has poor fluidity, resulting in greater resistance as it moves across the screen. This causes the slag to accumulate on the screen surface, necessitating the replacement of the springs to increase the vibration amplitude, which is inconvenient. Utility Model Content

[0004] The purpose of this invention is to solve the technical problems mentioned above, and to propose a vibrating feeder dewatering screen for slag.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a vibrating feeder dewatering screen for slag, comprising a base, four support plates on the surface of the base, a conveyor belt between the four support plates, multiple through holes evenly distributed on the surface of the conveyor belt, a water storage tank placed on the surface of the base, and an auxiliary device on the surface of the base, the auxiliary device comprising two uprights fixedly installed on the surface of the base, sliding plates slidably connected to the surfaces of the two uprights, a connecting rod fixedly installed between the two sliding plates, and a first spring fixedly installed between the sliding plates and the base. The first spring serves to limit the position of the sliding plates on the surface of the uprights.

[0006] Preferably, a U-shaped frame is fixedly installed on the side of the slide plate, and grooves are formed on the inner wall surfaces of both sides of the U-shaped frame. A screen is slidably inserted between two of the grooves. The grooves facilitate the connection between the screen and the U-shaped frame.

[0007] Preferably, two sliding rods are fixedly mounted on the surface of the base, and sliders are slidably connected to the surfaces of both sliding rods. A strip frame is fixedly mounted between the two sliders, and the inner surfaces of both sides of the strip frame are provided with tooth-like structures. Two round rods are fixedly mounted between the strip frame and the U-shaped frame. The round rods are designed to drive the U-shaped frame to move.

[0008] Preferably, a vertical plate is fixedly mounted on the surface of the base, a motor is fixedly mounted on the surface of the vertical plate, and a special-shaped gear is fixedly mounted on the output end of the motor. Only one-third of the teeth on the surface of the special-shaped gear are visible, and the special-shaped gear meshes with the tooth-like structures on the inner walls of both sides of the strip frame. The motor effectively drives the special-shaped gear to rotate.

[0009] Preferably, a limiting device is provided on one side surface of the screen, the limiting device including a groove formed on one side surface of the screen, a movable plate slidably connected inside the groove, and a rod fixedly installed on the surface of the movable plate, with an insertion hole formed on the inner wall surface of one of the slide grooves. The rod and insertion hole effectively limit the screen to be positioned inside the slide groove.

[0010] Preferably, a rectangular plate is fixedly mounted on one side surface of the screen, and a second spring is fixedly mounted between the rectangular plate and the movable plate. The second spring serves to limit the position of the movable plate inside the groove.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by setting an auxiliary device, when dewatering is required, the slag is first poured onto the screen, then the motor is turned on. The motor starts and drives the shaped gear to rotate. When the shaped gear rotates and meshes with the tooth-like structure on the inner wall surface of the left side of the strip frame, the strip frame will move upward. The upward movement of the strip frame drives the round rod to move upward, the round rod drives the U-shaped frame to move upward, the U-shaped frame drives the screen to move upward, and at the same time, the upward movement of the U-shaped frame also drives the slide plate to move upward on the surface of the upright. The upward movement of the slide plate on the surface of the upright will cause the first spring to stretch. At the same time, the upward movement of the strip frame also drives the slider to move upward on the surface of the slide rod. When the shaped gear rotates and meshes with the tooth-like structure on the inner wall surface of the right side of the strip frame, the strip frame will move downward. This ultimately drives the U-shaped frame downwards, which in turn moves the screen downwards. As the motor drives the shaped gear to rotate continuously, the screen moves back and forth up and down. In conjunction with the first spring, this creates vibration, thus removing moisture from the slag. The removed moisture passes through the screen, the through-holes on the conveyor belt, and finally flows into the water storage tank. The slag on the screen moves slowly forward under the action of vibration and falls onto the conveyor belt. Then, the conveyor belt is started, transporting the slag to the next station. Through the coordination of the above structure, the first spring, in conjunction with the continuous rotation of the shaped gear, causes the screen to vibrate. Even when the performance of the first spring decreases, the continuous rotation of the shaped gear can continue to provide vibration, thereby improving the sustainable dewatering performance of the device.

[0013] 2. In this utility model, by setting a limiting device, when it is necessary to replace the filter screen, firstly, the sliding plate is slid, so that the sliding plate moves inside the groove. The movement of the sliding plate inside the groove will squeeze the second spring, causing the second spring to be compressed. At the same time, the movement of the sliding plate inside the groove will also drive the insertion rod to move. The movement of the insertion rod will cause it to move out of the insertion hole. The separation of the insertion rod and the insertion hole will cause the screen to lose its limiting position inside the slide groove. At this time, the screen can be pulled out from the inside of the slide groove, completing the screen disassembly operation. Through the cooperation of the above structure, the purpose of disassembling the screen is achieved, so that the device can select a screen with a suitable screen hole according to the size of the slag.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a vibrating feeder dewatering screen for slag, including a base 1, four support plates 5 on the surface of the base 1, a conveyor belt 6 between the four support plates 5, a plurality of through holes 7 evenly opened on the surface of the conveyor belt 6, and a water storage tank 2 placed on the surface of the base 1.

[0023] The specific settings and functions of its auxiliary device 3 and limiting device 4 will be explained below.

[0024] In this embodiment: the surface of the base 1 is provided with an auxiliary device 3, which includes two uprights 301. The two uprights 301 are fixedly installed on the surface of the base 1. The surfaces of the two uprights 301 are slidably connected with sliding plates 302. A connecting rod 303 is fixedly installed between the two sliding plates 302. A first spring 304 is fixedly installed between the sliding plates 302 and the base 1.

[0025] In this embodiment, the first spring 304 serves to limit the position of the slide plate 302 on the surface of the upright 301.

[0026] Specifically, a U-shaped frame 305 is fixedly installed on the side of the slide plate 302. Slide grooves 306 are opened on the inner wall surfaces of both sides of the U-shaped frame 305, and a screen 307 is slidably inserted between the two slide grooves 306.

[0027] In this embodiment, the groove 306 facilitates the connection between the screen 307 and the U-shaped frame 305.

[0028] Specifically, two slide rods 308 are fixedly mounted on the surface of the base 1. Sliding blocks 309 are slidably connected to the surfaces of both slide rods 308. A strip frame 310 is fixedly mounted between the two sliding blocks 309. The inner surfaces of both sides of the strip frame 310 are provided with tooth-like structures. Two round rods 311 are fixedly mounted between the strip frame 310 and the U-shaped frame 305. The round rods 311 serve to move the U-shaped frame 305.

[0029] Specifically, a vertical plate 312 is fixedly mounted on the surface of the base 1, and a motor 313 is fixedly mounted on the surface of the vertical plate 312. A special-shaped gear 314 is fixedly mounted on the output end of the motor 313. Only one-third of the teeth on the surface of the special-shaped gear 314 are visible, and the special-shaped gear 314 meshes with the tooth-like structures on the inner walls of both sides of the strip frame 310. The motor 313 drives the special-shaped gear 314 to rotate.

[0030] In this embodiment: a limiting device 4 is provided on one side surface of the screen 307. The limiting device 4 includes a groove 41. The groove 41 is opened on one side surface of the screen 307. A movable plate 42 is slidably connected inside the groove 41. A plug rod 43 is fixedly installed on the surface of the movable plate 42. An insertion hole 44 is opened on the inner wall surface of one of the slide grooves 306. When the filter screen needs to be replaced, first slide the movable plate 42, causing it to move inside the groove 41. This movement compresses the second spring 46. Simultaneously, the movement of the movable plate 42 also moves the insertion rod 43, causing it to move out of the insertion hole 44. The separation of the insertion rod 43 and the insertion hole 44 causes the screen 307 to lose its restraint within the sliding groove 306. At this point, the screen 307 can be pulled out of the sliding groove 306, completing the disassembly of the screen 307. Through the coordination of the above structures, the purpose of disassembling the screen 307 is achieved, allowing the device to select a screen 307 with appropriate mesh size according to the slag dimensions.

[0031] Specifically, a rectangular plate 45 is fixedly installed on one side surface of the screen 307, and a second spring 46 is fixedly installed between the rectangular plate 45 and the movable plate 42.

[0032] In this embodiment, the second spring 46 serves to limit the position of the moving plate 42 inside the groove 41.

[0033] Working principle: By setting auxiliary device 3, when dewatering is required, the slag is first poured onto screen 307, then motor 313 is turned on. Motor 313 drives the shaped gear 314 to rotate. When the shaped gear 314 rotates and meshes with the tooth-like structure on the inner left side surface of the strip frame 310, the strip frame 310 will move upward. The upward movement of the strip frame 310 drives the round rod 311 to move upward. The upward movement of the round rod 311 drives the U-shaped frame 305 to move upward. The upward movement of frame 305 causes screen 307 to move upward. Simultaneously, the upward movement of U-shaped frame 305 also causes slide plate 302 to move upward on the surface of upright rod 301. The upward movement of slide plate 302 on the surface of upright rod 301 stretches the first spring 304. At the same time, the upward movement of strip frame 310 causes slider 309 to move upward on the surface of slide rod 308. When the shaped gear 314 rotates and meshes with the toothed structure on the inner right side surface of strip frame 310, it causes strip frame 310 to... The bar frame 310 moves downward, which in turn drives the U-shaped frame 305 downward, causing the screen 307 to move downward. As the motor 313 drives the gear 314 to rotate continuously, the screen 307 moves up and down repeatedly. In conjunction with the first spring 304, vibration is generated, thereby removing the water from the slag. The removed water passes through the screen 307, the through holes 7 on the conveyor belt 6, and finally flows into the water storage tank 2. Under the action of vibration, the slag on the screen 307 slowly moves forward and falls onto the conveyor belt 6. Then the conveyor belt 6 is started, and the slag is transferred to the next station. Through the cooperation of the above structure, the first spring 304 and the gear 314 rotate continuously, causing the screen 307 to vibrate. Therefore, when the performance of the first spring 304 decreases, the continuous rotation of the gear 314 can continue to provide vibration, thereby improving the sustainable dewatering performance of the device. When the filter screen needs to be replaced, first slide the movable plate 42, causing it to move inside the groove 41. This movement compresses the second spring 46. Simultaneously, the movement of the movable plate 42 also moves the insertion rod 43, causing it to move out of the insertion hole 44. The separation of the insertion rod 43 and the insertion hole 44 causes the screen 307 to lose its restraint within the sliding groove 306. At this point, the screen 307 can be pulled out of the sliding groove 306, completing the disassembly of the screen 307. Through the coordination of the above structures, the purpose of disassembling the screen 307 is achieved, allowing the device to select a screen 307 with appropriate mesh size according to the slag dimensions.
