Description

Technical Field

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

[0002] In the production process of P84 blended membrane filter bags, P84 fibers easily absorb moisture in humid environments, causing the fibers to swell and affecting the tensile and abrasion resistance of the filter bags. Drying can remove moisture from the fibers and maintain the stability of the material's physical properties, so a drying device is required.

[0003] A Chinese patent with authorization announcement number CN222881575U discloses a drying device for cleaning dust collector bags, including a device cylinder with a first fixed plate and a second fixed plate installed at the upper and lower ends of the cylinder, respectively. The top of the rotating tube is a sealed structure, and both sides of the rotating tube are connected to a first connecting pipe. The end of the first connecting pipe away from the rotating tube is a sealed structure. This utility model can cover multiple dust collector bags on the surface of the first and second connecting pipes. The dust collector bags are opened by the second connecting pipes. Due to the presence of a first water-air dual-purpose pump, water in the bottom shell can be extracted to directly clean the dust collector bags. After the water in the bottom shell is used up, hot air can be drawn into multiple second connecting pipes and sprayed out to dry multiple dust collector bags. The cleaning mechanism and the drying mechanism are integrated into one unit.

[0004] However, the aforementioned drying device still has some problems. In practical applications, the filter bag is only heated on one side during the drying process, which results in the filter bag not being dried evenly, leading to a decrease in the performance of the filter bag and affecting its effectiveness. Therefore, a filter bag processing and drying device is proposed to address these issues. 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 filter bag processing and drying device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A filter bag processing and drying device of this utility model includes a drying box. A rotating disk is rotatably installed on the inner wall of the bottom side of the drying box. A support plate is installed on the outer side of the rotating disk. An mounting plate is installed on the top side of the support plate. A hollow shaft is rotatably installed through the mounting plate at equal intervals. Several ventilation holes are evenly spaced inside the hollow shaft. A driven gear is installed at the bottom end of the hollow shaft. A drive motor is installed on the top side of the rotating disk. A driving gear is installed at the output end of the drive motor. The driving gear and the driven gear mesh with each other. A rotating tube is rotatably installed through the top side of the drying box. Four connecting pipes are evenly spaced on the outer side of the rotating tube. Several nozzles are equidistantly installed on the outer side of the connecting pipe. One end of the connecting pipe is a flexible tube, and the other end is a rigid tube. The flexible end of the connecting pipe extends movably into the bottom end of the hollow shaft. The drive motor drives the active gear to rotate. The active gear and the driven gear mesh with each other, thereby driving the hollow shaft to rotate. At the same time, hot air is blown out through the rotating pipe, the connecting pipe, the nozzles, and the ventilation holes. The nozzles and ventilation holes are used to dry the outer and inner sides of the filter bag, respectively, realizing the all-round air blowing and drying operation of the filter bag. With the cooperation of the active gear and the driven gear, the drive motor drives the hollow shaft to rotate, causing the filter bag to rotate. This allows the outer side of the filter bag to receive hot air evenly, ensuring that the drying degree of each part of the filter bag is consistent and improving the drying quality.

[0007] Preferably, three sets of sleeves are equidistantly installed on the outer side of the hollow shaft. A spring is fixedly connected inside the sleeve, and a movable rod is fixedly connected to one end of the spring. One end of the movable rod slides through to the outer side of the sleeve. An arc-shaped support plate is installed at one end of the three movable rods in the vertical direction. When the filter bag to be dried is put on the outside of the arc-shaped support plate, the elasticity of the spring allows the movable rod to automatically extend and retract according to the size of the filter bag, thereby adjusting the degree of opening of the arc-shaped support plate and realizing the effective fixation of filter bags of different sizes.

[0008] Preferably, the rotating disk has four equidistant limiting holes on its outer side. A connecting plate is installed inside the bottom side of the drying box, and a locking screw is rotatably installed inside the connecting plate. One end of the locking screw passes through one of the limiting holes. When it is necessary to fit the filter bag, the locking screw is rotated to disengage it from the limiting hole, and the rotating disk can rotate freely, making it easy to accurately fit the filter bag on the outside of the arc-shaped support plate. After the filter bag is fitted, the locking screw is rotated again to insert it into the corresponding limiting hole to position and fix the rotating disk, ensuring the stability of the device during the drying process. After the rotating disk is fixed, one end of the connecting tube hose is inserted into the bottom end of the hollow shaft.

[0009] Preferably, an exhaust pipe is installed on the top side of the drying chamber, and two fixing plates are symmetrically installed on the top side of the drying chamber. One end of the fixing plates is fitted with an installation cavity. Several air inlets are equidistantly opened inside the top side of the installation cavity. A negative pressure motor is installed inside the top side of the installation cavity, and five fan blades are installed at the output end of the negative pressure motor. A heating mesh plate is fitted on the inner wall of the bottom end of the installation cavity. The top end of the rotating tube is rotatably installed inside the bottom side of the installation cavity. When the negative pressure motor is working, it drives the fan blades to rotate, drawing in outside air through the air inlets. The air is heated by the heating mesh plate to form hot air. The hot air enters the connecting pipe and the hollow shaft through the rotating tube, and is finally blown out from the ventilation hole, providing a stable and sufficient supply of hot air for drying the filter bags, ensuring that the drying operation can be carried out continuously and efficiently.

[0010] Preferably, a hinged door is installed on one side of the drying oven, and a handle is installed on one side of the door. By opening the door with the handle, the filter bag can be easily placed on or removed from the arc-shaped support plate, making the operation simple.

[0011] Preferably, a control panel is installed on one side of the drying oven. The control panel is electrically connected to the electrical components inside the device and is used to operate and control the electrical components inside the device. Operators can easily operate and control the electrical components inside the device, such as the drive motor, negative pressure motor, and heating grid plate, to realize functions such as starting, stopping, and adjusting the drying temperature and wind speed.

[0012] The advantages of this utility model are: 1. The present invention uses a drive motor to rotate a drive gear, which meshes with a driven gear to rotate a hollow shaft, thereby causing the filter bag fitted on the arc-shaped support plate to rotate. Hot air enters the connecting pipe through the rotating pipe, and the nozzles on the connecting pipe dry the outside of the filter bag. At the same time, hot air enters the hollow shaft through a hose and vents the inside of the filter bag to dry it. The rotation of the filter bag ensures that all parts are heated evenly, ensuring consistent drying and achieving efficient and uniform filter bag drying. 2. In this invention, the filter bags to be dried are respectively fitted onto the outside of the arc-shaped support plate. Because the spring inside the outer sleeve of the hollow shaft is elastic, it will push the movable rod to extend and retract, and automatically adjust the degree of opening of the arc-shaped support plate according to the size of the filter bag, thus achieving effective fixation of filter bags of different sizes.

Detailed Implementation

[0016] 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.

[0017] Please see Figure 1-5As shown, a filter bag processing and drying device includes a drying chamber 1. A rotating disk 2 is rotatably mounted on the bottom inner wall of the drying chamber 1. A support plate 201 is mounted on the outer side of the rotating disk 2. An mounting plate 202 is mounted on the top side of the support plate 201. A hollow shaft 203 is rotatably mounted through the mounting plate 202 at equal intervals. A plurality of ventilation holes 204 are evenly spaced inside the hollow shaft 203. A driven gear 205 is mounted at the bottom end of the hollow shaft 203. A drive motor 2 is mounted on the top side of the rotating disk 2. 06. The output end of the drive motor 206 is equipped with a drive gear 207, which meshes with the driven gear 205. A rotating tube 208 is rotatably installed through the top side of the drying box 1. Four connecting tubes 209 are equidistantly installed on the outer side of the rotating tube 208. Several nozzles 210 are equidistantly installed on the outer side of the connecting tubes 209. One end of the connecting tube 209 is a flexible tube, and the other end is a rigid tube. The flexible end of the connecting tube 209 extends movably into the bottom end of the hollow shaft 203. An exhaust pipe 5 is installed on the top side of the drying box 1. Two fixing plates 501 are symmetrically installed on the top side of the drying box 1. An installation cavity 502 is installed at one end of the fixing plates 501. Several air inlets 503 are equidistantly opened inside the top side of the installation cavity 502. A negative pressure motor 504 is installed inside the top side of the installation cavity 502. Five fan blades 505 are installed at the output end of the negative pressure motor 504. A heating mesh plate 506 is assembled on the inner wall of the bottom end of the installation cavity 502. The top end of the rotating tube 208 is rotatably installed inside the bottom side of the installation cavity 502. A control panel 7 is installed on one side of the drying chamber 1. The control panel 7 is electrically connected to the electrical components inside the device and is used to control the operation of the electrical components inside the device. During operation, in practical applications, the filter bag is only heated on one side during the drying process, which results in the filter bag not being dried evenly. This leads to a decrease in the performance of the filter bag and affects its usage effect. When the control panel 7 is started, the negative pressure motor 504 is turned on, and the five fan blades 505 at its output end begin to rotate. Outside air is drawn in through the air inlet 503 on the top side of the mounting cavity 502. The air is heated by the heating mesh plate 506 on the inner wall of the bottom end of the mounting cavity 502 to form hot air. The hot air enters the connecting pipe 209 and the hollow shaft 203 through the rotating pipe 208, providing a stable and sufficient hot air source for drying the filter bag. During the drying process, the drive motor 206 starts, and the drive gear 207 at its output end rotates, meshing with the driven gear 205, driving the hollow shaft 203 to rotate. This causes the filter bag fitted on the arc-shaped support plate 303 to rotate accordingly. Hot air enters the connecting pipe 209 through the rotating pipe 208. The nozzles 210 on the connecting pipe 209 blow hot air outwards from the filter bag for external drying. At the same time, hot air enters the hollow shaft 203 through one end of the connecting pipe 209 hose, and then blows hot air outwards from the internal ventilation holes 204 to the inside of the filter bag for internal drying. During the rotation of the filter bag, all parts can receive hot air evenly from the nozzles 210 and ventilation holes 204, ensuring that the entire filter bag is dried to a uniform degree and improving the drying quality. The hot and humid exhaust gas generated during the drying process is discharged through the exhaust pipe 5.

[0018] Please see Figure 1-5 As shown, three sets of sleeves 3 are equidistantly installed on the outer side of the hollow shaft 203. A spring 301 is fixedly connected inside the sleeve 3. One end of the spring 301 is fixedly connected to a movable rod 302. One end of the movable rod 302 slides through to the outer side of the sleeve 3. An arc-shaped support plate 303 is installed on one end of the three movable rods 302 in the vertical direction. The rotating disk 2 has four equidistant limiting holes 4 on its outer side. A connecting plate 401 is installed inside the bottom side of the drying box 1. A locking screw 402 is rotatably installed inside the connecting plate 401. One end of the locking screw 402 passes through one of the limiting holes 4. A hinged door 6 is installed on one side of the drying chamber 1, and a handle 601 is installed on one side of the door 6. During operation, in the production process of P84 blended membrane filter bags, P84 fibers easily absorb moisture in a humid environment, causing the fibers to swell and affecting the tensile strength and wear resistance of the filter bags. Drying can remove the moisture from the fibers and maintain the stability of the material's physical properties. Therefore, a drying device is required. First, the door 6 is opened by pulling open the handle 601 to open the drying chamber 1. The locking screw 402 inside the connecting plate 401 is rotated to disengage it from the limiting hole 4 on the outside of the rotating disk 2. At this time, the rotating disk 2 can rotate freely. This makes it easy to fit the filter bags to be dried onto the outside of the arc-shaped support plate 303. Since the spring 301 inside the sleeve 3 on the outside of the hollow shaft 203 is elastic, it will push the movable rod 302 to extend and retract when the filter bags are fitted. The degree of opening of the arc-shaped support plate 303 will be automatically adjusted according to the size of the filter bags to fix the filter bags. After the filter bag is fixed, rotate the locking screw 402 to insert into the limiting hole 4 to position the rotating disk 2 and prevent it from rotating randomly during the drying process. At the same time, place one end of the connecting pipe 209 hose into the bottom of the hollow shaft 203 to complete the filter bag loading and device preparation. After drying is complete, turn off the drive motor 206, negative pressure motor 504 and other electrical components, rotate the locking screw 402 to disengage it from the limit hole 4, rotate the rotating disk 2, rotate the arc support plate 303 containing the filter bag to a position close to the movable door 6, open the movable door 6 through the handle 601, and remove the dried filter bag from the arc support plate 303 to complete the entire filter bag drying process.

[0019] Working principle: First, open the movable door 6 by pulling the handle 601 to open the drying box 1, rotate the locking screw 402 inside the connecting plate 401 to disengage it from the limiting hole 4 on the outside of the rotating disk 2, at which point the rotating disk 2 can rotate freely; This makes it easy to fit the filter bags to be dried onto the outside of the arc-shaped support plate 303. Since the spring 301 inside the sleeve 3 on the outside of the hollow shaft 203 is elastic, it will push the movable rod 302 to extend and retract when the filter bags are fitted. The degree of opening of the arc-shaped support plate 303 will be automatically adjusted according to the size of the filter bags to fix the filter bags. After the filter bag is fixed, rotate the locking screw 402 to insert into the limiting hole 4 to position the rotating disk 2 and prevent it from rotating randomly during the drying process. At the same time, place one end of the connecting pipe 209 hose into the bottom of the hollow shaft 203 to complete the filter bag loading and device preparation. Start the control panel 7 and turn on the negative pressure motor 504. The five fan blades 505 at its output end start to rotate and draw in outside air through the air inlet 503 on the top side of the mounting cavity 502. The air passes through the heating mesh plate 506 on the inner wall of the bottom end of the mounting cavity 502 and is heated to form hot air. The hot air enters the connecting pipe 209 and the hollow shaft 203 through the rotating pipe 208, providing a stable and sufficient hot air source for drying the filter bag. During the drying process, the drive motor 206 starts, and the drive gear 207 at its output end rotates and meshes with the driven gear 205, driving the hollow shaft 203 to rotate. This causes the filter bag fitted on the arc-shaped support plate 303 to rotate accordingly. Hot air enters the connecting pipe 209 through the rotating pipe 208. The nozzle 210 on the connecting pipe 209 blows hot air outwards to dry the outside of the filter bag. At the same time, hot air enters the hollow shaft 203 through one end of the connecting pipe 209 hose and then blows hot air outwards to the inside of the filter bag through the ventilation hole 204 inside the shaft, thus drying the inside of the filter bag. During the rotation of the filter bag, all parts can receive hot air from the nozzle 210 and the ventilation hole 204 evenly, ensuring that the drying degree of the entire filter bag is consistent and improving the drying quality. The hot and humid exhaust gas generated during the drying process is discharged through the exhaust pipe 5. After drying is complete, turn off the drive motor 206, negative pressure motor 504 and other electrical components, rotate the locking screw 402 to disengage it from the limit hole 4, rotate the rotating disk 2, rotate the arc support plate 303 containing the filter bag to a position close to the movable door 6, open the movable door 6 through the handle 601, and remove the dried filter bag from the arc support plate 303 to complete the entire filter bag drying process.
