Description

Technical Field

[0001] This utility model relates to the field of vacuum belt dewatering machines, and in particular to a vacuum belt dewatering machine with good stability. 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. After the filter cake is conveyed to the unloading area by the filter cloth, some filter cake remains on the filter cloth. Traditional vacuum belt dewatering machines have scrapers at this point to remove the filter cake adhering to the filter cloth. However, cleaning the filter cloth only with scrapers leaves some filter cake residue. First, the residual filter cake increases the resistance of the filter cloth, leading to a decrease in dewatering efficiency and causing the moisture content of solids such as gypsum to exceed the standard, affecting product quality. Second, the residue can also cause filter cloth clogging, reducing its service life and increasing the cost of replacing the filter cloth. In addition, the residual filter cake can also cause belt misalignment, affecting the sealing of the vacuum chamber, leading to a decrease in vacuum level, further affecting the dewatering effect. Ultimately, this affects the stability of the vacuum belt dewatering machine, thus requiring a vacuum belt dewatering machine with high stability. Utility Model Content

[0003] The main purpose of this invention is to provide a vacuum belt dewatering machine with good stability, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A stable vacuum belt dewatering machine includes a main body with a support bracket fixedly installed at its rear end. A secondary cleaning assembly is mounted on the support bracket. The secondary cleaning assembly consists of a drive motor, a rotating prism, mounting shafts, an anti-detachment plate, striking rods, rubber plates, and vibration springs. There are two mounting shafts, each fixedly mounted at one end of the rotating prism. The anti-detachment plate is fixedly mounted at one end of one of the mounting shafts. The other mounting shaft is fixedly connected to the output shaft of the drive motor. There are three striking rods arranged in a ring on the outside of the rotating prism. There are three rubber plates, each fixedly mounted on the outer wall of one of the striking rods. Several vibration springs connect the three striking rods to the rotating prism. The vibration springs are fixedly connected to the striking rods and the rotating prism.

[0006] Preferably, a filter belt is installed on the main body of the device.

[0007] Preferably, the support bracket consists of a frame plate, support vertical plates, and connecting brackets. There are two support vertical plates that are symmetrically fixed to the upper end of the frame plate, and there are two connecting brackets that are symmetrically fixed to the front end of the frame plate.

[0008] Preferably, the connecting bracket on the support bracket is fixedly installed at the rear end of the equipment body, and the support vertical plate has a shaft hole.

[0009] Preferably, a cleaning scraper is fixedly installed at the rear end of the frame plate on the support bracket, and the cleaning scraper is in contact with the filter belt.

[0010] Preferably, the rotating prism on the secondary cleaning assembly is located between two supporting vertical plates, the mounting shaft is rotatably installed in the shaft hole opened on the supporting vertical plate, the anti-detachment plate is located on the outside of one of the supporting vertical plates, the drive motor is fixedly installed on the outer end of the other supporting vertical plate, and the rubber plate can contact the filter belt.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By setting up a support bracket and installing a secondary cleaning component on it, the secondary cleaning component can perform a secondary cleaning of the filter belt after it has been cleaned by the scraper. At this time, the drive motor drives the rotating prism, vibration spring, striking rod, and rubber plate to rotate, so that the striking rod and rubber plate strike the filter belt, causing the filter belt to vibrate. This causes the filter cake remaining on the filter belt to be shaken off, ultimately reducing the probability of filter cake remaining on the filter belt, thereby reducing the resistance of the filter belt, ensuring the dehydration rate, and ensuring that the product moisture content meets the requirements. At the same time, it increases the service life of the filter belt, thereby improving the stability of the vacuum belt dewatering machine. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a vacuum belt dewatering machine with good stability includes a main body 1. A support bracket 2 is fixedly installed at the rear end of the main body 1. A secondary cleaning component 4 is installed on the support bracket 2. The secondary cleaning component 4 consists of a drive motor 10, a rotating prism 11, a mounting shaft 12, an anti-detachment plate 13, striking rods 14, rubber plates 15, and vibration springs 16. There are two mounting shafts 12, which are fixedly installed at both ends of the rotating prism 11. The anti-detachment plate 13 is fixedly installed at one end of one of the mounting shafts 12. The other mounting shaft 12 is fixedly connected to the output shaft of the drive motor 10. There are three striking rods 14, which are arranged in a ring on the outside of the rotating prism 11. There are three rubber plates 15, which are fixedly installed on the outer walls of the three striking rods 14. There are several vibration springs 16, which connect the three striking rods 14 to the rotating prism 11. A filter belt 5 is installed on the main body 1. The vibration springs 16 and the striking rods... 14. The rotating prism 11 is fixedly connected. 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 quickly drawn away under negative pressure. The water in the slurry enters the vacuum chamber through the filter cloth, 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 being processed 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 cleaning scraper 3, so that the cleaning scraper 3 can scrape off the filter cake stuck on the filter belt 5, completing the unloading. At the same time, the secondary cleaning component 4 can be started to perform secondary cleaning on the filter belt 5, thereby reducing the filter cake remaining on the filter belt 5.

[0021] Finally, by setting up a support bracket 2 and a secondary cleaning component 4 on the support bracket 2, the secondary cleaning component 4 can perform secondary cleaning on the filter belt 5 after it has been cleaned by the cleaning scraper 3. At this time, the drive motor 10 will drive the rotating prism 11, the vibration spring 16, the striking rod 14 and the rubber plate 15 to rotate, so that the striking rod 14 and the rubber plate 15 strike the filter belt 5, causing the filter belt 5 to vibrate, thereby shaking off the filter cake remaining on the filter belt 5, thus reducing the probability of filter cake remaining on the filter belt 5, thereby reducing the resistance of the filter belt 5, ensuring the dehydration rate, making the product moisture content meet the requirements, and increasing the service life of the filter belt 5, thereby improving the stability of the vacuum belt dehydrator.

[0022] Specifically, the support bracket 2 consists of a frame plate 6, support vertical plates 7, and connecting brackets 8. Two support vertical plates 7 are symmetrically fixed to the upper end of the frame plate 6. Two connecting brackets 8 are symmetrically fixed to the front end of the frame plate 6. The connecting brackets 8 on the support bracket 2 are fixedly installed at the rear end of the equipment body 1. A shaft hole 9 is provided on the support vertical plate 7. A cleaning scraper 3 is fixedly installed at the rear end of the frame plate 6 on the support bracket 2, and the cleaning scraper 3 contacts the filter belt 5. The rotating prism 11 on the secondary cleaning assembly 4 is located between the two support vertical plates 7. The mounting shaft 12 is rotatably installed in the shaft hole 9 on the support vertical plate 7. The anti-detachment plate 13 is located on the outside of one of the support vertical plates 7. The drive motor 10 is fixedly installed on the other support vertical plate 7. At the outer end of the support plate 7, the rubber plate 15 can contact the filter belt 5. When the secondary cleaning component 4 is activated to perform secondary cleaning and unloading of the filter belt 5, the drive motor 10 can be started. At this time, the drive motor 10 will drive the rotating prism 11, the mounting shaft 12, the anti-detachment plate 13, the striking rod 14, the rubber plate 15, and the vibration spring 16 to rotate. The rotating striking rod 14 and the rubber plate 15 will strike the filter belt 5, causing the filter belt 5 to vibrate. At the same time, under the influence of this impact force and the elastic force of the vibration spring 16, the striking rod 14 and the rubber plate 15 will vibrate, and this vibration will be transmitted to the filter belt 5, thereby increasing the vibration frequency of the filter belt 5, so that the filter cake remaining on the filter belt 5 can be cleaned off more effectively.
