Description

Technical Field

[0001] This utility model relates to the field of dust collector filter bag processing technology, specifically a drying device for processing dust collector filter bags. Background Technology

[0002] Dust collector filter bags are the core filtration elements of baghouse dust collectors. They are usually cylindrical. During the production process, filter bags may contain a certain amount of moisture due to processing technology, material properties, etc. The presence of moisture can clog the pores of the filter bag and reduce its air permeability. Drying can remove the moisture, keep the pores of the filter bag open, and thus ensure its good air permeability, ensuring that it can effectively filter dust in the air during use.

[0003] Existing filter bag drying equipment includes a box body with a rotating disk on the bottom inner wall of the box body. A supporting structure is fixed on the rotating disk. A heating system is installed inside the box body. When drying the filter bags, the box door is first opened, and the filter bags are placed on the supporting structure. Then the box door is closed, and the air pump is started to blow air into the box body. At the same time, the heating tube is turned on to heat the air inside the box body. Simultaneously, the motor is started to rotate the supporting structure, which in turn causes the filter bags to rotate, thus enabling the filter bags to be dried from all directions.

[0004] Existing drying devices for filter bag processing can only heat and dry the outer surface of the filter bag. Since filter bags are usually composed of multiple layers, heat cannot penetrate to the deeper layers when drying only the outside. Relying solely on the external heat source cannot effectively evaporate the heat. The temperature difference between the inside and outside of the filter bag is large, which can easily lead to uneven heating of the filter bag. This uneven heating may cause the filter bag to deform, shrink, or twist, affecting its dimensional accuracy and appearance quality. Therefore, a drying device for dust collector filter bag processing is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a drying device for processing dust filter bags.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The drying device for processing dust collector filter bags according to this utility model includes a hollow base, a drying box is provided on the hollow base, a hollow rotating column is rotatably installed inside the drying box, a plurality of air holes are opened on the hollow rotating column, a rotating disk is fitted at the bottom end of the hollow rotating column, two fixing rings are fitted on the rotating disk, and four electric push rods are installed on each fixing ring. The working ends of two electric push rods on the same vertical plane are fitted with support fixing rods. Before drying, the opening is first opened, the filter bag is placed on the outside of the support fixing rods, and the electric push rods are started to make the support fixing rods move closer or further apart, so as to fix filter bags of different diameters, which facilitates the subsequent drying treatment of filter bags of different diameters. This solves the problem that traditional drying devices can only process filter bags of a single specification, and significantly expands the application range of the equipment. Preferably, a driven gear is fitted at the bottom of the hollow rotating column, and the driven gear is located inside the hollow base. An electric motor is installed inside the hollow base, and a driving gear is installed at the output end of the electric motor. The driving gear and the driven gear mesh with each other. Two first fixed sleeves are fixedly connected to one side wall of the drying chamber, and a hollow tube is fitted onto the two first fixed sleeves. Multiple air outlets are connected to the hollow tube, and the air outlets are located inside the drying chamber. A heating chamber is installed on the top side of the drying chamber, and a heating tube is installed inside the heating chamber. Two air inlets are opened on the top side of the heating chamber, and a fan is installed in each of the two air inlets. A first air supply pipe is connected to one side wall of the heating chamber, and the other end of the first air supply pipe is connected to the hollow tube. A second air supply pipe is connected to the other side wall of the heating chamber, and the other end of the second air supply pipe is rotatably connected to the bottom of the hollow rotating column. At the opening, after the filter bag is fixed, during drying, a fan operates, and with the assistance of the heating tube, the heated high-temperature gas flows into the hollow tube and the hollow rotating column through the first and second air supply pipes respectively. Finally, the high-temperature gas is sprayed onto the outer surface of the filter bag through the air outlet and onto the inner wall of the filter bag through multiple air vents. At the same time, the motor is started, causing the hollow rotating column, rotating disk, and fixed filter bag to rotate. By combining synchronous internal and external drying with dynamic rotational drying, the inner and outer surfaces of the filter bag are simultaneously exposed to hot air. Heat can be transferred to all parts of the filter bag more quickly, accelerating moisture evaporation and eliminating the problem of internal moisture residue caused by drying only on the outside. At the same time, it ensures that the hot air evenly covers the inner and outer surfaces of the filter bag, avoiding deformation, shrinkage, or twisting of the filter bag caused by uneven heating of the inner and outer surfaces, ensuring the drying effect and improving the processing quality of the filter bag.

[0007] Preferably, two second fixed sleeves are installed on the outer wall of the drying box, and the second air supply pipe passes through the two second fixed sleeves in sequence. When using the device, the second fixed sleeves provide rigid support for the second air supply pipe, preventing the pipe from sagging or shaking due to its own weight or airflow impact, and ensuring a stable and reliable connection between the pipe and the box.

[0008] Preferably, a battery is installed on the rotating disk, and the battery powers the electric actuator. When using the device, by setting up the battery, the electric actuator does not need to rely on an external power cord, thus avoiding the problem of wire tangling when the hollow rotating column drives the electric actuator to rotate.

[0009] Preferably, the drying chamber has a pre-reserved opening, and a sealing door is hinged to one side of the opening via a hinge. The sealing door is equipped with a handle and an observation window. When using the device, the drying status of the filter bags inside the chamber can be observed in real time through the observation window, so that any abnormalities can be detected in time and corresponding measures can be taken.

[0010] Three air outlet pipes are connected to one side wall of the drying oven away from the sealed door, and each air outlet pipe is equipped with a dustproof net. During the drying process, the air outlet pipes facilitate the timely discharge of moisture from the oven, and the dustproof nets prevent external dust from entering the oven.

[0011] Preferably, a control panel is installed on one side wall of the drying oven, and the control panel is used to control the start and stop of the motor, electric push rod, fan and heating tube. When using the device, by setting up the control panel, multiple drive devices can be integrated together, which can integrate control and improve the convenience of operation.

[0012] The advantages of this utility model are: 1. Before drying, the opening is first opened, the filter bag is placed on the outside of the support rod, and the electric push rod is started to move the support rod closer or further apart, so that filter bags of different diameters can be fixed, which facilitates the subsequent drying of filter bags of different diameters. This solves the problem that traditional drying devices can only handle filter bags of a single specification, and significantly expands the scope of application of the equipment. 2. After the filter bag of this utility model is fixed, during drying, the fan operates, and with the cooperation of the heating tube, the heated high-temperature gas flows into the hollow tube and the hollow rotating column through the first and second air supply pipes respectively. Finally, the high-temperature gas is sprayed onto the outer surface of the filter bag through the air outlet and onto the inner wall of the filter bag through multiple air vents. At the same time, the motor is started, causing the hollow rotating column, rotating disk and the fixed filter bag to rotate. By combining synchronous internal and external drying with dynamic rotational drying, the inner and outer surfaces of the filter bag are simultaneously exposed to hot air. The heat can be transferred to all parts of the filter bag more quickly, accelerating the evaporation of moisture and eliminating the problem of internal moisture residue caused by drying only on the outside. At the same time, it ensures that the hot air evenly covers the inner and outer surfaces of the filter bag, avoiding deformation, shrinkage or twisting of the filter bag caused by uneven heating of the inner and outer surfaces, ensuring the drying effect and improving the processing quality of the filter bag.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0016] Please see Figure 1-5 As shown, a drying device for processing dust collector filter bags includes a hollow base 1, a drying chamber 2 mounted on the hollow base 1, a hollow rotating column 3 rotatably mounted inside the drying chamber 2, multiple air vents 5 on the hollow rotating column 3, a rotating disk 4 fitted at the bottom end of the hollow rotating column 3, two fixing rings 6 fitted on the rotating disk 4, and four electric push rods 7 mounted on each fixing ring 6. Support fixing rods 8 are fitted to the working ends of two electric push rods 7 on the same vertical plane. During operation, when drying the filter bags, the opening 23 is first opened, the filter bag is placed on the outside of the support fixing rods 8, and the electric push rods 7 are activated to move the support fixing rods 8 closer or further apart, thus fixing filter bags of different diameters. This facilitates subsequent drying of filter bags of different diameters, solving the problem that traditional drying devices can only process filter bags of a single specification, and significantly expanding the applicability of the equipment. A driven gear 9 is fitted at the bottom of the hollow rotating column 3, and the driven gear 9 is located inside the hollow base 1. A motor 10 is installed inside the hollow base 1, and a driving gear 11 is installed at the output end of the motor 10. The driving gear 11 meshes with the driven gear 9. Two first fixed sleeves 12 are fixedly connected to one side wall of the drying chamber 2. Hollow tubes 13 are fitted onto the two first fixed sleeves 12. Multiple air outlets 14 are connected to the hollow tubes 13, and the air outlets 14 are located inside the drying chamber 2. A heating chamber 15 is installed on the top side of the drying chamber 2. A heating tube 16 is provided, and two air inlets 17 are opened on the top side of the heating box 15. A fan 18 is installed in each of the two air inlets 17. A first air supply pipe 19 is connected to one side wall of the heating box 15, and the other end of the first air supply pipe 19 is connected to a hollow tube 13. A second air supply pipe 20 is connected to the other side wall of the heating box 15, and the other end of the second air supply pipe 20 is rotatably connected to the bottom port of the hollow rotating column 3. During operation, after the filter bag is fixed, during drying, the opening 23 is resealed through the sealing door 24, and then... When the fan 18 operates, in conjunction with the heating tube 16, it blows the heated high-temperature gas into the first gas delivery pipe 19 and the second gas delivery pipe 20 respectively. The high-temperature gas in the first gas delivery pipe 19 flows into the hollow tube 13 and is finally sprayed onto the outer surface of the filter bag through the air outlet 14. The high-temperature gas in the second gas delivery pipe 20 flows into the hollow rotating column 3 and is sprayed onto the inner wall of the filter bag through multiple air vents 5. At the same time, the motor 10 is started, causing the drive gear 11 to rotate, which forces the driven gear 9 to drive the hollow rotating column 3, the rotating disk 4, and the fixed assembly. The filter bag rotates, allowing for all-around drying. By combining synchronous internal and external drying with dynamic rotational drying, the filter bag's interior and exterior are simultaneously exposed to hot air. This allows heat to be transferred to all parts of the filter bag more quickly, accelerating moisture evaporation and eliminating the problem of residual internal moisture caused by drying only on the outside. At the same time, it ensures that hot air evenly covers the inner and outer surfaces of the filter bag, preventing deformation, shrinkage, or twisting of the filter bag due to uneven heating of the inner and outer surfaces. This guarantees the drying effect and improves the processing quality of the filter bag. Two second fixed sleeves 21 are installed on the outer wall of the drying oven 2, and the second air supply pipe 20 passes through the two second fixed sleeves 21 in sequence. When the device is in operation, the second fixed sleeves 21 provide rigid support for the second air supply pipe 20 to prevent the pipe from sagging or shaking due to its own weight or airflow impact, and ensure that the connection between the pipe and the oven is stable and reliable. A battery 22 is installed on the rotating disk 4, and the battery 22 supplies power to the electric push rod 7. When the device is in operation, by setting the battery 22, the electric push rod 7 does not need to rely on an external power cord, thus avoiding the problem of wire tangling when the hollow rotating column 3 drives the electric push rod 7 to rotate. Please see Figure 1-2 As shown, the drying chamber 2 has a pre-reserved opening 23. A sealing door 24 is hinged to one side of the opening 23 via a hinge. The sealing door 24 is equipped with a handle 25 and an observation window 26. During operation, when using this device, the drying status of the filter bags in the chamber can be observed in real time through the observation window 26, so that any abnormalities can be detected in time and corresponding measures can be taken. Three air outlet pipes are connected to one side wall of the drying oven 2 away from the sealed door 24, and each air outlet pipe is equipped with a dustproof net. During operation, the air outlet pipes facilitate the timely discharge of moisture from the oven, and the dustproof nets prevent external dust from entering the oven. A control panel 27 is installed on one side wall of the drying oven 2. The control panel 27 is used to control the start and stop of the motor 10, electric push rod 7, fan 18 and heating tube 16. When the device is in operation, by setting up the control panel 27, multiple drive devices can be integrated together, which can integrate control and improve the convenience of operation. Working Principle: Existing drying devices for filter bags can only heat and dry the outer surface of the filter bag. Since filter bags are usually composed of multiple layers, heat cannot penetrate to the deeper layers when drying only the outside. External heat sources alone cannot effectively evaporate the heat, resulting in a large temperature difference between the inside and outside of the filter bag. This uneven heating can cause the filter bag to deform, shrink, or twist, affecting its dimensional accuracy and appearance quality. Therefore, a new drying device for dust collector filter bags is proposed to address these issues. When drying the filter bag, the opening 23 is first opened, and the filter bag is placed on the outside of the support rod 8. The electric push rod 7 is then activated, causing the support rods 8 to move closer or further apart, thus fixing filter bags of different diameters. This facilitates subsequent drying of filter bags of different diameters, solving the problem that traditional drying devices can only handle filter bags of a single size and significantly expanding the applicability of the equipment. After the filter bag is fixed, during drying, the opening 23 is resealed through the sealing door 24. Then, the blower 18, in conjunction with the heating tube 16, blows the heated high-temperature gas into the first gas supply pipe 19 and the second gas supply pipe 20 respectively. The high-temperature gas in the first gas supply pipe 19 flows into the hollow tube 13 and is finally sprayed onto the outer surface of the filter bag through the air outlet 14. The high-temperature gas in the second gas supply pipe 20 flows into the hollow rotating column 3 and is sprayed onto the inner wall of the filter bag through multiple air vents 5. At the same time, the motor 10 is started, causing the drive gear 11 to rotate, forcing the driven gear... 9 drives the hollow rotating column 3, rotating disk 4, and fixed filter bag to rotate, thereby enabling all-round drying of the filter bag. By combining synchronous internal and external drying with dynamic rotational drying, the inside and outside of the filter bag are simultaneously exposed to hot air. Heat can be transferred to all parts of the filter bag more quickly, accelerating moisture evaporation and eliminating the problem of internal moisture residue caused by drying only on the outside. At the same time, it ensures that hot air evenly covers the inner and outer surfaces of the filter bag, avoiding deformation, shrinkage, or twisting of the filter bag caused by uneven heating of the inner and outer surfaces, thus ensuring the drying effect and improving the processing quality of the filter bag.
