Description

Technical Field

[0001] This utility model relates to the field of vacuum belt dewatering machines, and in particular to a feeding structure for a vacuum belt dewatering machine. Background Technology

[0002] Vacuum belt dewatering machines, also known as fixed vacuum chamber rubber belt filters, are high-efficiency, continuously operating solid-liquid separation machines. They utilize the gravity of materials and vacuum suction to achieve solid-liquid separation, and are widely used in solid-liquid separation in metallurgy, mining, chemical, papermaking, food, pharmaceutical, and environmental protection industries, especially excelling in gypsum dewatering in wet flue gas desulfurization. During operation, the slurry is conveyed onto a filter cloth carried by a heavy-duty rubber belt. The holes in the filter cloth and the grooves in the belt allow the liquid to flow into the vacuum chamber. After the vacuum pump starts, the air and filtrate under the filter cloth are rapidly drawn away under negative pressure. The water in the slurry passes through the filter cloth into the vacuum chamber, while the solid particles gradually form a filter cake. Subsequently, the mixture of filtrate and air enters a gas-liquid separator for separation. The gas is drawn away by the vacuum pump, and the filtrate is discharged into a receiving tank. After processing in the forming zone, rinsing zone, and drying zone, the filter cake is finally dried and sent out in the unloading zone.

[0003] The existing patent application with application number CN202123036738.8 proposes a modularly designed vacuum belt dewatering machine. Although its high-speed rotating brush roller can clean the underside of the vacuum belt, scraping off the gypsum residue remaining on the underside of the vacuum belt, reducing gypsum residue residue and extending service life, a large amount of residue will adhere to the bristles of the brush roller during the cleaning process. This will affect the cleaning effect of the brush roller on the vacuum belt, resulting in a poor cleaning effect and making it impossible to clean the vacuum belt thoroughly. Utility Model Content

[0004] The main objective of this invention is to provide a feeding structure for a vacuum belt dewatering machine, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A feeding structure for a vacuum belt dewatering machine includes a mounting bracket, which is fixedly installed at the rear end of the main body of the equipment. The mounting bracket consists of a mounting base plate and connecting brackets. Two connecting brackets are symmetrically fixedly installed at the front end of the mounting base plate. An adjustable cleaning component is mounted on the mounting base plate. The adjustable cleaning component consists of a threaded rod, a guide rod, a water tank, a connecting pipe, a rotating roller, cleaning brush bristles, and a drive motor. The threaded rod is rotatably installed at the lower end of the water tank. There are two guide rods, both fixedly installed at the lower end of the water tank. There are two connecting pipes, each inserted into one side wall of the water tank. The rotating roller is rotatably installed inside the water tank. The cleaning brush bristles are fixedly installed on the outer wall of the rotating roller. The drive motor is fixedly installed at one end of the water tank, and the output shaft of the drive motor is fixedly connected to the rotating roller.

[0007] Preferably, a filter belt is installed on the main body of the device.

[0008] Preferably, a scraper is fixedly installed at the rear end of the water tank on the adjustable cleaning assembly, and the scraper is in contact with the filter belt.

[0009] Preferably, the connecting bracket on the mounting bracket is fixedly installed at the rear end of the equipment body. The mounting base plate has threaded holes and limiting holes. There are two limiting holes, which are symmetrically arranged on both sides of the threaded hole. Both the threaded hole and the limiting hole penetrate the mounting base plate vertically.

[0010] Preferably, the adjustable cleaning component has two symmetrical mounting holes on the two side walls of the water tank, the guide rod is movably inserted into the limiting hole, the threaded rod is installed in the threaded hole, the water tank is located above the mounting base plate, and the connecting pipe is connected to the water circulation filtration device.

[0011] Preferably, the rotating roller on the adjustable cleaning assembly is rotatably mounted in two mounting holes opened in the water tank, and the cleaning bristles are in contact with the filter belt.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By incorporating an adjustable cleaning assembly consisting of a threaded rod, guide rod, water tank, connecting pipe, rotating roller, cleaning brush bristles, and drive motor, water is injected into the water tank during the cleaning process of the filter belt by the rotating roller and cleaning brush bristles driven by the drive motor. This cleans the cleaning brush bristles, keeping them relatively clean and ensuring a good cleaning effect on the filter belt. Simultaneously, the mounting bracket, in conjunction with the threaded rod and guide rod on the adjustable cleaning assembly, allows for adjustment of the height of the scraper, water tank, rotating roller, cleaning brush bristles, and drive motor. This ensures that the cleaning brush bristles and scraper can continue to contact the filter belt even after wear, thereby extending their service life and reducing the frequency of replacement, thus lowering maintenance costs.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a feeding structure for a vacuum belt dewatering machine includes a mounting bracket 2, which is fixedly installed at the rear end of the main body 1. The mounting bracket 2 consists of a mounting base plate 6 and connecting brackets 7. There are two connecting brackets 7, which are symmetrically fixedly installed at the front end of the mounting base plate 6. An adjustable cleaning assembly 3 is installed on the mounting base plate 6. The adjustable cleaning assembly 3 consists of a threaded rod 10, a guide rod 11, a water tank 12, a connecting pipe 13, a rotating roller 15, cleaning brushes 16, and a drive motor 17. The threaded rod 10 is rotatably installed at the lower end of the water tank 12. There are two guide rods 11, both of which are fixedly installed at the lower end of the water tank 12. There are two connecting pipes 13, each of which is fixedly installed at the lower end of the water tank 12. The rotating roller 15 is rotatably installed inside the water tank 12, and the cleaning brush bristles 16 are fixedly installed on the outer wall of the rotating roller 15. The drive motor 17 is fixedly installed at one end of the water tank 12, and the output shaft of the drive motor 17 is fixedly connected to the rotating roller 15. A filter belt 5 is installed on the main body 1 of the equipment. A scraper 4 is fixedly installed at the rear end of the water tank 12 on the adjustable cleaning component 3, and the scraper 4 is in contact with the filter belt 5. During operation, the slurry can be transported to the filter belt 5, which is conveyed by a heavy-duty rubber belt. The holes on the filter belt 5 and the grooves on the belt allow the liquid to flow into the vacuum tank. After the vacuum pump is started, the air and filtrate below the filter belt 5 are removed. Under negative pressure, the water in the slurry is rapidly drawn away through the filter cloth into the vacuum chamber, while the solid particles gradually form a filter cake. Subsequently, the mixture of filtrate and air enters the gas-liquid separator for separation. The gas is drawn away by the vacuum pump, and the filtrate is discharged into the receiving container. After processing in the forming zone, rinsing zone, and drying zone, the filter cake finally becomes dry and is sent out in the unloading zone. At the same time, the filter belt 5 will rub against the scraper 4, so that the scraper 4 can scrape off the filter cake stuck on the filter belt 5, completing the feeding. During this process, the drive motor 17 can be started, thereby driving the rotating roller 15 and the cleaning brush 16 to rotate. At this time, the cleaning brush 16 will also rub against the filter belt 5. Friction is generated on the filter belt 5, which can further clean the filter belt 5 and finally clean and discharge the filter cake remaining on the filter belt 5. At the same time, water can be injected into the water tank 12, so that the cleaning bristles 16 can be cleaned as the cleaning bristles 16 rotate, thus keeping the cleaning bristles 16 in a relatively clean state. When the cleaning bristles 16 and scraper 4 are worn due to friction with the filter belt 5 and can no longer contact the filter belt 5, the threaded rod 10 can be rotated on the mounting bracket 2 to adjust the height of the cleaning bristles 16 and scraper 4, so that the worn cleaning bristles 16 and scraper 4 can still contact the filter belt 5.

[0022] Therefore, by setting up an adjustable cleaning assembly 3 consisting of a threaded rod 10, a guide rod 11, a water tank 12, a connecting pipe 13, a rotating roller 15, cleaning bristles 16, and a drive motor 17, water can be injected into the water tank 12 during the process of the rotating roller 15 and cleaning bristles 16 being driven by the drive motor 17 to clean the filter belt 5. This allows the cleaning bristles 16 to be cleaned and kept in a relatively clean state, ultimately enabling the cleaning bristles 16 to maintain a good cleaning effect on the filter belt 5. At the same time, the mounting bracket 2 cooperates with the threaded rod 10 and guide rod 11 on the adjustable cleaning assembly 3 to adjust the height of the scraper 4, water tank 12, rotating roller 15, cleaning bristles 16, and drive motor 17. This allows the cleaning bristles 16 and scraper 4 to continue to contact the filter belt 5 even after wear, thereby increasing the service life of the cleaning bristles 16 and scraper 4, ultimately reducing the replacement frequency of the cleaning bristles 16 and scraper 4, and reducing maintenance costs.

[0023] Specifically, the connecting bracket 7 on the mounting bracket 2 is fixedly installed at the rear end of the main body 1. The mounting base 6 has threaded holes 9 and limiting holes 8. There are two limiting holes 8 symmetrically arranged on both sides of the threaded hole 9, and both the threaded hole 9 and the limiting holes 8 penetrate the mounting base 6 vertically. Two mounting holes 14 are symmetrically opened on the side walls of the water tank 12 on the adjustable cleaning component 3. The guide rod 11 is movably inserted into the limiting hole 8, and the threaded rod 10 is installed in the threaded hole 9. The water tank 12 is located above the mounting base 6. The connecting pipe 13 is connected to the water circulation filtration equipment. The rotating roller 15 on the adjustable cleaning component 3 is rotatably installed in the two mounting holes 14 on the water tank 12. The cleaning bristles 16 contact the filter belt 5. In use, the water circulation filtration connected to the adjustable cleaning component 3 can be activated. The equipment allows water to be injected into the water tank 12 through one of the connecting pipes 13. When the drive motor 17 is started, it drives the rotating roller 15 and the cleaning brush 16 to rotate in the water tank 12. At this time, the cleaning brush 16 cleans the filter belt 5 and also comes into contact with the water in the water tank 12, thus completing self-cleaning. The water in the water tank 12 will flow back into the water circulation filtration equipment through the other connecting pipe 13. When adjusting the height of the cleaning brush 16 and the scraper 4, the threaded rod 10 can be rotated in the threaded hole 9 on the mounting bracket 2. At this time, the guide rod 11, the water tank 12, the connecting pipe 13, the rotating roller 15, the cleaning brush 16, and the drive motor 17 will be driven by the threaded rod 10. When the cleaning brush 16 and the scraper 4 come into contact with the filter belt 5, the rotation of the threaded rod 10 can be stopped.
