Description

Technical Field

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

[0002] Filter bags are a key component used in filtration equipment. They are usually made of fibrous materials and have a bag-like structure. During the production process of filter bags, the filter cloth needs to be impregnated. After impregnation, a uniform film is formed on the surface of the fiber of the filter cloth. This helps to improve the filtration accuracy of the filter media, enabling the filter bag to more effectively intercept and separate solid particles, dust and other impurities in gases or liquids.

[0003] A Chinese patent with publication number CN107142629A discloses a filter bag production impregnation device, including an impregnation chamber. A first guide wheel and a second guide wheel are respectively installed on a set of opposing inner walls inside the impregnation chamber. A first pressing wheel group and a second pressing wheel group are installed between another set of opposing inner walls inside the impregnation chamber. A cover plate is installed on the top of the impregnation chamber, and a feeding roller and a receiving roller are installed on the top of the cover plate. Filter bag felt is wound on the feeding roller. This invention greatly improves the absorption rate of negative ion slurry by the filter bag felt, resulting in very thorough absorption and thus improving the quality of the filter bag. The operation is also very simple.

[0004] The aforementioned filter bag production impregnation device can only agitate the impregnation liquid in the middle area of ​​the impregnation tank when impregnating the filter cloth. Agitating only the impregnation liquid in the middle area will cause a concentration gradient to form at the edge of the solution, resulting in uneven distribution of the composition and concentration of the impregnation liquid in the impregnation tank, which will affect the impregnation effect and reduce the processing quality of the filter bag. Therefore, a filter bag production impregnation device 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, this utility model proposes a filter bag production impregnation device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A filter bag production impregnation device of this utility model includes a cavity base, an impregnation tank fixedly connected to the cavity base, two protective shells at the bottom of the impregnation tank, and three first rotating rods rotatably mounted on the two protective shells. Each first rotating rod has multiple first stirring blades fixedly mounted on it, and a first bevel gear is fitted at both ends of each first rotating rod. Three second rotating rods are rotatably mounted on both sides of the interior of the impregnation tank, and three fixing plates are fixedly connected to the inner walls on both sides of the top of the impregnation tank. The top of each second rotating rod is correspondingly rotatably mounted on... On the fixed plate, the bottom end of the second rotating rod penetrates the protective shell. Multiple second stirring blades are fixedly connected to each second rotating rod. A second bevel gear is fitted at the bottom end of each second rotating rod. Both the first and second bevel gears are housed within the protective shell and mesh with each other. Two first motors are installed on the inner wall of the bottom side of the cavity base. The output end of the first motor is connected to the bottom end of the second rotating rod located in the middle. From top to bottom, the bottom end of the second rotating rod in the middle is fitted with a first pulley and a second pulley. The second rotating rod on both sides... A third pulley and a fourth pulley are respectively fitted onto the two rotating rods. A first conveyor belt is fitted onto the first and third pulleys, and a second conveyor belt is fitted onto the second and fourth pulleys. Support frames are fixed to both sides of the top of the impregnation tank. A second motor is mounted on the top side of the support frames, and the output end of the second motor is connected to the third rotating rod. Multiple third stirring blades are fixed on the third rotating rod. During the impregnation of the filter cloth, the first motor drives the middle second rotating rod to rotate, thereby causing the first and second pulleys and the second rotating rods on both sides to rotate synchronously. Under the bevel gear meshing mechanism, the first and second stirring blades rotate in tandem, agitating the impregnation liquid on both sides and the bottom of the impregnation tank. Simultaneously, the second motor drives the third stirring blade to rotate, thereby rotating the impregnation liquid in the middle of the impregnation tank. Through agitation of the sides, bottom, and middle areas of the impregnation tank, the impregnation liquid in the impregnation tank can be thoroughly and deeply agitated, effectively preventing the precipitation or uneven distribution of impregnation liquid components, maintaining the uniformity of impregnation liquid composition and concentration, providing a stable and consistent impregnation environment for the filter bags, and significantly improving the impregnation quality of the filter bags.

[0007] Preferably, two upright plates are fixed to both sides of the port of the impregnation box, and two upright plates on the same side are rotatably mounted with a first guide roller. Two second guide rollers are rotatably mounted inside the top port of the impregnation box, and two impregnation rollers are rotatably mounted inside the impregnation box. Before impregnating the filter bag, the first guide roller, the second guide roller and the impregnation roller are scientifically arranged to construct a precise conveying path for the filter cloth, ensuring that the filter cloth can maintain a stable, continuous and uniform movement during the impregnation process, which greatly improves the efficiency and quality stability of the filter bag impregnation process.

[0008] Preferably, two support seats are fixed to the outer wall of the impregnation chamber, and a drying chamber is installed on the two support seats. Two mounting holes are opened on the top and bottom sides of the drying chamber, and a fan is installed in each mounting hole. Two sets of heating tubes are installed inside the drying chamber, and the two sets of heating tubes are located on the upper and lower sides of the drying chamber respectively. Openings are opened on both sides of the drying chamber. When drying the impregnated filter cloth, the fan and heating tubes work together to form a high-temperature airflow, which is precisely applied to the upper and lower sides of the filter cloth to achieve efficient and rapid drying and curing of the impregnation liquid. The high-temperature gas heats the filter cloth on both sides simultaneously to ensure that the filter cloth is heated evenly as a whole, avoiding the problem of uneven drying or residual impregnation liquid, thereby effectively ensuring the consistency of the quality of the filter cloth after impregnation and drying.

[0009] Preferably, a drain pipe is connected to the bottom of one side of the impregnation tank, and a one-way valve is installed on the drain pipe. When the impregnation operation is completed, the impregnation liquid in the impregnation tank can be discharged by setting up the drain pipe.

[0010] Preferably, a control panel is installed on the outer wall of the impregnation tank, and the control panel is used to control the start and stop of the first motor, the second motor, the fan and the heating tube. When using the device, the control panel serves as a centralized control hub for centrally controlling the start and stop of the key components, the first motor, the second motor, the fan and the heating tube.

[0011] The advantages of this utility model are:

[0012] 1. In the process of impregnating filter cloth, the present invention uses a first electric motor to drive the second rotating rod in the middle to rotate, which in turn drives the first and second pulleys and the second rotating rods on both sides to rotate synchronously. Under the meshing mechanism of the first bevel gear, the first stirring blade and the second stirring blade are rotated in tandem to agitate the impregnation liquid on both sides and the bottom of the impregnation tank. At the same time, the second electric motor drives the third rotating rod to rotate the third stirring blade, which in turn rotates the impregnation liquid in the middle of the impregnation tank. By agitating the impregnation liquid on both sides, the bottom and the middle of the impregnation tank, the impregnation liquid in the impregnation tank can be agitated comprehensively and deeply, effectively preventing the components of the impregnation liquid from settling or being unevenly distributed, maintaining the uniformity of the components and concentration of the impregnation liquid, providing a stable and consistent impregnation environment for the filter bag, and significantly improving the impregnation quality of the filter bag.

[0013] 2. In the drying process of the impregnated filter cloth, the present invention uses a fan and a heating tube to work together to form a high-temperature airflow, which is precisely applied to both the top and bottom surfaces of the filter cloth. This achieves efficient and rapid drying and curing of the impregnation liquid. The high-temperature gas heats both sides of the filter cloth simultaneously, ensuring that the filter cloth is heated evenly and avoiding uneven drying or residual impregnation liquid in some areas. This effectively ensures the consistency of the quality of the filter cloth after impregnation and drying. Attached Figure Description

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.

[0024] Please see Figure 2-6As shown, a filter bag production impregnation device includes a cavity base 1, an impregnation tank 2 fixedly connected to the cavity base 1, two protective shells 3 at the bottom of the impregnation tank 2, three first rotating rods 4 rotatably mounted on the two protective shells 3, each first rotating rod 4 having multiple first stirring blades 5 fixedly mounted on it, and each first rotating rod 4 having a first bevel gear 6 fitted at both ends. Three second rotating rods 8 are rotatably mounted on both sides of the interior of the impregnation tank 2, and three fixing plates 7 are fixedly connected to the inner walls on both sides of the top of the impregnation tank 2. The top of each second rotating rod 8 is rotatably mounted on a corresponding fixing plate 7, and the bottom end of the second rotating rod 8 penetrates through the protective shell 3. Multiple second stirring blades 9 are fixedly mounted on each second rotating rod 8. The bottom end of each of the second rotating rods 8 is fitted with a second bevel gear 10, and both the first bevel gear 6 and the second bevel gear 10 are housed within the protective shell 3, meshing with each other. Two first motors 11 are mounted on the inner wall of the bottom side of the cavity base 1. The output end of each first motor 11 is connected to the bottom end of the second rotating rod 8 located in the middle. From top to bottom, the bottom end of the second rotating rod 8 in the middle is fitted with a first pulley 12 and a second pulley 13. The second rotating rods on both sides are fitted with a third pulley 14 and a fourth pulley 15, respectively. The first pulley 12 and the third pulley 14 are fitted with a first conveyor belt 16, and the second pulley 13 and the fourth pulley 15 are fitted with a first conveyor belt 16. A second conveyor belt 17 is fitted onto a pulley 15. Support frames 18 are fixedly connected to both sides of the top of the impregnation tank 2. A second motor 19 is mounted on the top side of the support frame 18. The output end of the second motor 19 is connected to a third rotating rod 20, on which multiple third stirring blades 21 are fixed. During operation, when impregnating the fabric, the first motor 11 is started, causing the second rotating rod 8 in the middle to drive the first pulley 12 and the second pulley 13 to rotate. With the cooperation of the first conveyor belt 16 and the second conveyor belt 17, the second rotating rods 8 on both sides also rotate. The second rotating rods 8 drive the second stirring blades 9 and the second bevel gear 10 to rotate. The first bevel gear 6 meshes... As the device rotates, the three first rotating rods 4 drive the first stirring blades 5 to rotate. Through the rotation of the first stirring blades 5 and the second stirring blades 9, the impregnation liquid on both sides and the bottom of the impregnation tank 2 can be stirred. At the same time, the second motor 19 is started, causing the third rotating rod 20 to drive the third stirring blades 21 to rotate, thereby stirring the impregnation liquid in the middle of the impregnation tank 2. By stirring the sides, bottom and middle areas of the impregnation tank 2, the impregnation liquid in the impregnation tank 2 can be stirred comprehensively and deeply, effectively preventing the components of the impregnation liquid from settling or being unevenly distributed, maintaining the uniformity of the components and concentration of the impregnation liquid, providing a stable and consistent impregnation environment for the filter bags, and significantly improving the impregnation quality of the filter bags.

[0025] Please see Figure 1-3 and Figure 7As shown, two vertical plates 22 are fixed to both sides of the port of the impregnation tank 2. The two vertical plates 22 on the same side are rotatably mounted with first guide rollers 23. Two second guide rollers 24 are rotatably mounted inside the top port of the impregnation tank 2, and two impregnation rollers 25 are rotatably mounted inside the impregnation tank 2. During operation, before impregnating the filter bag, the filter cloth to be impregnated passes through the first guide roller 23, the outside of the second guide roller 24, and the bottom of the impregnation roller 25 in sequence, and exits from the top of another first guide roller 23. Through the scientifically arranged first guide rollers 23, second guide rollers 24 and impregnation rollers 25, a precise conveying path for the filter cloth is constructed, ensuring that the filter cloth can maintain a stable, continuous and uniform movement during the impregnation process, which greatly improves the efficiency and quality stability of the filter bag impregnation process.

[0026] Two support seats 26 are fixed to the outer wall of the impregnation chamber 2. The two support seats 26 are used to install the drying chamber 27. Two mounting holes are opened on the top and bottom sides of the drying chamber 27. A fan 29 is installed in each mounting hole. Two sets of heating tubes 30 are installed inside the drying chamber 27. The two sets of heating tubes 30 are located on the upper and lower sides of the drying chamber 27 respectively. Openings 28 are opened on both sides of the drying chamber 27. During operation, when drying the impregnated filter cloth, the filter cloth directly enters the drying chamber 27 after impregnation. The fan 29 and the heating tubes 30 work together to form a high-temperature airflow, which is precisely applied to the upper and lower sides of the filter cloth to achieve efficient and rapid drying and curing of the impregnation liquid. The high-temperature gas heats the filter cloth on both sides simultaneously to ensure that the filter cloth is heated evenly and avoids the problem of uneven drying or residual impregnation liquid. This effectively ensures the consistency of the quality of the filter cloth after impregnation and drying.

[0027] A drain pipe 31 is connected to the bottom of one side of the immersion tank 2, and a one-way valve is installed on the drain pipe 31. During operation, at the end of the immersion operation, the immersion liquid in the immersion tank 2 can be discharged by setting the drain pipe 31.

[0028] A control panel 32 is installed on the outer wall of the immersion tank 2, and the control panel 32 is used to control the start and stop of the first motor 11, the second motor 19, the fan 29 and the heating tube 30. When the device is in operation, the control panel 32 serves as a centralized control hub to centrally control the start and stop of the key components, the first motor 11, the second motor 19, the fan 29 and the heating tube 30.

[0029] Working Principle: The above-mentioned filter bag production impregnation device can only agitate the impregnation liquid in the middle area of ​​the impregnation tank 2 when impregnating the filter cloth. Agitating only the impregnation liquid in the middle area will cause a concentration gradient to form at the edge of the solution, resulting in uneven distribution of the composition and concentration of the impregnation liquid in the impregnation tank 2, which will affect the impregnation effect and reduce the processing quality of the filter bag. Therefore, to address the above problem, a filter bag production impregnation device is proposed. Before impregnating the filter bag, the filter cloth to be impregnated is passed through the first guide roller 23 above, the outside of the second guide roller 24, and the bottom of the impregnation roller 25 in sequence, and then passes out from the top of another first guide roller 23, thus constructing a precise conveying path for the filter cloth, which facilitates the conveying and impregnation process of the filter cloth.

[0030] When impregnating the fabric, the first motor 11 is started, causing the second rotating rod 8 in the middle to drive the first pulley 12 and the second pulley 13 to rotate. With the cooperation of the first conveyor belt 16 and the second conveyor belt 17, the second rotating rods 8 on both sides also rotate. The second rotating rods 8 drive the second stirring blades 9 and the second bevel gear 10 to rotate. Under the meshing rotation of the first bevel gear 6, the three first rotating rods 4 drive the first stirring blades 5 to rotate. Through the rotation of the first stirring blades 5 and the second stirring blades 9, the fabric can be... The impregnation liquid on both sides and the bottom of the impregnation tank 2 is stirred. At the same time, the second motor 19 is started, which causes the third rotating rod 20 to drive the third stirring blade 21 to rotate. This allows the impregnation liquid in the middle of the impregnation tank 2 to rotate. By stirring the impregnation liquid on both sides, the bottom and the middle area of ​​the impregnation tank 2, the impregnation liquid in the impregnation tank 2 can be stirred comprehensively and deeply, effectively preventing the components of the impregnation liquid from settling or being unevenly distributed. This maintains the uniformity of the components and concentration of the impregnation liquid, provides a stable and consistent impregnation environment for the filter bag, and significantly improves the impregnation quality of the filter bag.

[0031] When drying the impregnated filter cloth, the filter cloth is directly placed into the drying chamber 27 after impregnation. The fan 29 and the heating tube 30 work together to form a high-temperature airflow, which is precisely applied to the upper and lower surfaces of the filter cloth to achieve efficient and rapid drying and curing of the impregnation liquid. The high-temperature gas heats the filter cloth on both sides simultaneously to ensure that the filter cloth is heated evenly and avoids the problem of uneven drying or residual impregnation liquid in some areas, thereby effectively ensuring the consistency of the quality of the filter cloth after impregnation and drying.
