Description
Technical Field
[0001] The utility model relates to the technical field of waste gas dust removal in grain drying towers, and more specifically, to a waste gas dust removal device for grain drying towers. Background Art
[0002] In the current agricultural processing field, grain drying towers are important equipment for improving grain storage quality. The problem of waste gas treatment generated during their operation has attracted increasing attention. A large amount of waste gas will be generated during the drying process of grain. These waste gases contain a large amount of dust and particulate matter, which poses a potential pollution threat to the environment. Therefore, the waste gas dust removal device of the grain drying tower is of vital importance. However, due to the huge amount of waste gas generated during the drying process, this brings huge processing pressure to the dust removal device. In actual operation, this large amount of waste gas treatment demand often leads to challenges for existing dust removal equipment, especially in adjusting the pressure relief value. Since the equipment failed to fully consider the demand for such large-scale processing volume during design, there are deficiencies in pressure regulation, which increases the instability of the equipment during operation.
[0003] Furthermore, when the waste gas dust removal device of the grain drying tower is processing a large amount of waste gas, if the pressure relief value cannot be effectively adjusted, the pressure inside the equipment may rise rapidly. This excessive pressure will not only affect the dust removal effect, but more seriously, it may pose a threat to the safety of the equipment itself. When the pressure exceeds the equipment's tolerance limit, equipment failure may occur, and even safety accidents such as explosions may occur. Therefore, ensuring that the dust removal device can operate stably under high load and can adjust the pressure relief value is an important part of ensuring the safe use of the grain drying tower and improving the level of environmental protection.

[0013] The utility model has at least the following beneficial effects:
[0014] Compared with the prior art, the utility model provides an exhaust gas dust removal device for a grain drying tower, which has the following beneficial effects:
[0015] 1. The beneficial effect of the pressure regulating mechanism is that it can effectively respond to the changes in pressure during the waste gas treatment process of the grain drying tower, automatically perform pressure relief adjustment, and ensure the safe and stable operation of the equipment. The pressure regulating mechanism collects dust in the waste gas through the filtering mechanism. As the use time increases, the pressure of the filter bag gradually increases. At this time, the telescopic sleeve slides upward along the receiving sleeve under the action of pressure, and the compression spring is used to relieve pressure. When the telescopic sleeve is unsealed from the receiving sleeve, the gas is discharged through the outlet pipe, thereby reducing the pressure on the filter bag and avoiding damage to the filter bag due to excessive pressure. This design enables the pressure regulating mechanism to intelligently respond to pressure changes and automatically adjust, thereby improving the service life and operating efficiency of the equipment.
[0016] 2. The beneficial effect of the fixing mechanism is that it provides a simple and accurate method for regulating the pressure of the pressure relief. By selecting fixing rods of different lengths, the fixing rods can be connected to different numbers of intermediate disks, thereby changing the compression state and spring coefficient of the spring. Since the sliding distance between the telescopic sleeve and the receiving sleeve remains unchanged, adjusting the length of the fixing rod can change the elastic force generated when the spring is compressed, thereby adjusting the pressure of the pressure relief. This design makes the regulation of the pressure relief simple and flexible, meets the needs of pressure regulation under different working conditions, and enhances the adaptability and operational convenience of the equipment.
[0017] 3. The beneficial effect of the filtering mechanism is that it efficiently realizes the dust removal treatment of exhaust gas, protects the environment, and ensures the normal operation of subsequent equipment. The multiple filter bags in the filtering mechanism can capture and collect dust particles generated during the grain drying process, preventing these particulate matter from being discharged into the atmosphere and causing pollution. As the pressure of the filter bag increases, the filtering mechanism can effectively relieve pressure through the cooperation of the pressure regulating mechanism to maintain normal filtration efficiency. This design not only improves the dust removal effect, but also ensures the stability and reliability of the equipment during long-term operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] See also Figure 1-5, used for grain drying tower exhaust gas dust removal device, including a tank body 1, the tank body 1 is installed on the external equipment, the tank body 1 is provided with a pressure regulating mechanism, the pressure regulating mechanism includes a filter mechanism, a sealing cover 2, a regulating pipe 3, an air outlet pipe 4, a spring 5, a socket 6, a telescopic sleeve 7 and a fixing mechanism, the filter mechanism is installed in the tank body 1, the sealing cover 2 is installed on the tank body 1, the pressure regulating pipe is connected to the sealing cover 2, one end of the air outlet pipe 4 is connected to the side wall of the regulating pipe 3, and the other end of the air outlet pipe 4 is connected to the external equipment, the socket 6 is coaxially installed on the inner wall of the regulating pipe 3, the telescopic sleeve 7 is slidably connected in the socket 6, and the telescopic sleeve 7 and the socket 6 are coaxially arranged, a spring 5 is installed on the telescopic sleeve 7, the other end of the spring 5 is connected to the upper end surface of the regulating pipe 3, the fixing mechanism is installed on the regulating pipe 3, the fixing mechanism includes an intermediate disk 8 and a fixing rod 9, a plurality of intermediate disks 8 are provided, and the plurality of intermediate disks 8 are equidistantly installed on the spring 5 On the upper side, the fixing rod 9 is threadedly connected to the intermediate disk 8, and a sealing tube 10 is coaxially provided on the upper end surface of the adjusting tube 3. The fixing rod 9 is threadedly connected to the sealing tube 10. A hexagonal sleeve 11 is provided on the fixing rod 9, and the hexagonal sleeve 11 fits on the sealing tube 10. A handle 12 is provided on the hexagonal sleeve 11. The handle 12 and the fixing rod 9 are coaxially arranged. A guide rod 13 is coaxially provided on the telescopic sleeve 7. A guide sleeve 14 is provided on the inner wall of the adjusting tube 3. The guide rod 13 slides Connected in the guide sleeve 14, the filtering mechanism includes a receiving plate 101 and a filter bag 102. The receiving plate 101 is installed on the inner wall of the tank body 1. There are multiple filter bags 102, and the multiple filter bags 102 are respectively installed on the receiving plate 101. An air inlet 15 is provided on the side wall of the tank body 1. The air inlet 15 is installed on the tank body 1 at the upper end of the receiving plate 101, and the air inlet 15 is connected to external equipment. A plurality of support legs 16 are provided on the lower end surface of the tank body 1.
[0030] In this embodiment, when a lot of waste gas is generated by grain drying, the waste gas needs to be passed into the tank body 1 through multiple filter bags 102 for dust removal. Due to long-term use of the filter bags 102, the passing pressure will gradually increase, so the pressure at the upper end will become larger and larger, so the pressure on the telescopic sleeve 7 will also become larger and larger, and then the telescopic sleeve 7 will be pushed to slide upward along the receiving sleeve 6. At this time, the spring 5 is continuously compressed. When the continuous movement causes the telescopic sleeve 7 to untie the seal between the receiving sleeve 6, the gas will be discharged through the outlet pipe 4, thereby relieving the pressure inside the tank body 1, avoiding damage to the filter bag 102, and the filtered gas is discharged through the outlet pipe 4, thereby completing the use process.
[0031] More specifically, when it is necessary to adjust the pressure of the pressure relief, first select fixed rods 9 of different lengths. Due to the different lengths, the fixed rods 9 can be threadedly connected to different numbers of intermediate disks 8. The springs 5 in the connected area are in a fixed state. At this time, only the spring 5 at the lower end can be compressed, thereby increasing the spring coefficient of the spring 5. Since the sliding distance between the telescopic sleeve 7 and the receiving sleeve 6 remains unchanged, when the spring coefficient becomes larger, the elastic force generated by moving the same distance becomes larger, thereby changing the pressure relief pressure, and thus completing the adjustment process.
[0032] In summary, when the whole equipment is in use or running: when a lot of waste gas is generated by grain drying, the waste gas needs to be passed into the tank body 1 through multiple filter bags 102 for dust removal. Due to the long-term use of the filter bags 102, the passing pressure will gradually increase, so the pressure at the upper end will become larger and larger, so the pressure on the telescopic sleeve 7 will also become larger and larger, and then the telescopic sleeve 7 will be pushed to slide upward along the receiving sleeve 6. At this time, the spring 5 is continuously compressed. When the continuous movement causes the telescopic sleeve 7 to untie the seal between the receiving sleeve 6, the gas will be discharged through the outlet pipe 4, thereby relieving the pressure inside the tank body 1 and avoiding the filter The bag 102 is damaged, and the filtered gas is discharged through the outlet pipe 4, thus completing the use process. When the pressure of the pressure relief needs to be adjusted, first select fixing rods 9 of different lengths. Due to the different lengths, the fixing rods 9 can be threadedly connected to different numbers of intermediate disks 8. The springs 5 in the connected area are in a fixed state. At this time, only the spring 5 at the lower end can be compressed, thereby increasing the spring coefficient of the spring 5. Since the sliding distance between the telescopic sleeve 7 and the receiving sleeve 6 remains unchanged, when the spring coefficient becomes larger, the elastic force generated by moving the same distance becomes larger, thereby changing the pressure of the pressure relief, thus completing the adjustment process.
