Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying equipment technology, and in particular to a dust removal device for a drying tower. Background Technology
[0002] Drying towers, also known as high-temperature continuous dryers, are mainly used to dry substances or materials with high humidity. They control humidity and temperature by heating air and passing it through the substance or material. This equipment is widely used in the production processes of many industries such as chemical, food processing, pharmaceutical, paper, and building materials. Especially in the food processing field, drying towers are often used to make dried fruits, dried vegetables, bean products, and other delicacies. The dust removal system can effectively remove impurities and dust from grains or materials, thereby improving their overall quality, which is particularly important for the food processing and pharmaceutical industries.
[0003] A search revealed Chinese patent CN213555952U, which discloses a dust removal device for the exhaust gas duct of a drying tower. This device addresses the issue that gravity dust removal using cyclone dust collectors is ineffective for lightweight dust and impurities, while baghouse dust collectors often suffer from dust and impurities mixing with moisture and adhering to the filter bags, making them difficult to remove with high-pressure air. Therefore, this device is installed in conjunction with a grain drying tower. It primarily improves upon existing baghouse dust collectors, addressing the problem of dust and impurities mixing with moisture and adhering to the filter bags, which is difficult to remove with high-pressure air. By setting up a dust filter to filter dust and impurities in the exhaust gas, and then using a dust scraper assembly to clean the dust and impurities from the filter to the impurity collection chamber, the device achieves the purpose of exhaust gas dust removal and solves the problem of dust and impurity condensation in existing devices, thus improving the quality and efficiency of exhaust gas dust removal.
[0004] When the dust removal device of the aforementioned drying tower is used, it is convenient to solve the problem of dust and impurities condensation in the existing device. However, when removing dust from the drying tower, some of the dust removal devices are set at higher positions in the drying tower. This makes it difficult and dangerous to replace the internal filter screens of the dust removal devices, increasing the complexity of the replacement process and reducing the efficiency of the replacement process.

[0033] As attached Figure 4 As shown, the assembly includes two fixed frames 10, which are fixedly connected inside the dust collection box 2. Multiple fixed shells 11 and multiple first springs 12 are fixedly connected to one side of each fixed frame 10. The first springs 12 are located inside the fixed shells 11. Sliding shells 13 are slidably connected inside the fixed shells 11. An installation frame 14 is fixedly connected to one side of each sliding shell 13. Two limiting shells 15 are fixedly connected to one side of the installation frame 14. The fixed frame 10 is used to install the first springs 12. The first springs 12 push the installation frame 14. The sliding shells 13 and the fixed shells 11 help to limit and protect the first springs 12.
[0034] As attached Figure 2As shown, a first filter 16 is provided on one side of one of the mounting frames 14, and a second filter 17 is provided on one side of the other mounting frame 14. The pore size of the first filter 16 is larger than that of the second filter 17, which helps to filter dust step by step.
[0035] As attached Figure 6 As shown, a fixed box 18 is fixedly connected to the middle of the limiting shell 15. A limiting rod 19 is slidably connected to one side of the fixed box 18. A limiting block 20 is fixedly connected to the middle of the limiting rod 19. A second spring 21 is fixedly connected to one side of the limiting block 20. One end of the second spring 21 is fixedly connected to the inner wall of the fixed box 18. A connecting rod 22 is fixedly connected to one end of each of the two limiting rods 19. The limiting rods 19 can easily engage with the through hole 33. The second spring 21 provides elastic pushing force to the limiting rods 19.
[0036] As attached Figure 5 As shown, two through holes 33 are provided in the middle of the first filter screen 16 and the second filter screen 17, which helps to engage the limiting rod 19.
[0037] As attached Figure 7 As shown, a dust collection assembly is provided on the lower surface of the dust collection box 2. The dust collection assembly includes a dust collection box 23, which is fixedly connected to the lower surface of the dust collection box 2. A dust discharge pipe 24 is connected through one side of the dust collection box 23. A dust cover 25 is provided at one end of the dust discharge pipe 24. A water tank 26 is fixedly connected to the lower surface of the dust collection box 23. The dust discharge pipe 24 is used to discharge the dust inside the dust collection box 23.
[0038] As attached Figure 1 As shown, a connecting pipe 27 is connected through the lower surface of the water tank 26, and a water pump 28 is installed through the middle of the connecting pipe 27. The water pump 28 is fixedly connected to one side of the dust collection box 23. A water inlet pipe 32 is connected through one side of the water tank 26. One end of the connecting pipe 27 is a double-ended pipe, which is used to connect two water outlet pipes 29.
[0039] As attached Figure 7 As shown, water outlet pipes 29 are connected to both ends of the connecting pipe 27. Multiple spray heads 30 are connected to one side of the water outlet pipe 29. Two water outlet pipes 29 are fixedly connected to the inside of the dust collection box 23. The spray heads 30 are used to spray mist to make the dust settle.
[0040] As attached Figure 3 As shown, two through slots 31 are provided on the lower surface of the dust collection box 2 for dust to settle and fall into the dust collection box 23.
[0041] Working principle: When removing dust from the inside of the drying tower body 1, close the door 5 and turn on the fan 3. The fan 3 uses suction to draw dust from the inside of the drying tower body 1 through the suction pipe 4 into the dust collection box 2. The dust will then pass through the first filter screen 16 and the second filter screen 17, and finally be discharged by the fan 3. When it is necessary to disassemble the first filter screen 16 and the second filter screen 17, pull the connecting rod 22 on the corresponding side. After the connecting rod 22 drives the two limiting rods 19 to be pulled out of the corresponding through hole 33, the first filter screen 16 and the second filter screen 17 are released from the limit. Then, the first filter screen 16 and the second filter screen 17 are pulled out from the corresponding two limiting shells 15 respectively, thereby disassembling the first filter screen 16 and the second filter screen 17. The above operation is reversed during installation.
[0042] When dust is blocked on one side of the first filter screen 16 and the second filter screen 17, the first spring 12 pushes the mounting frame 14 to vibrate, causing the mounting frame 14 to shake the first filter screen 16 and the second filter screen 17 respectively. Some dust will fall and fall into the dust collection box 23 through the through groove 31. Then, the water pump 28 is turned on, and water is pumped into the water tank 26 filled with water through the connecting pipe 27, so that the water flows to the water outlet pipe 29 and is then sprayed out through the spray head 30. When the dust is contaminated with water vapor, it will settle, thus facilitating the collection of dust.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
