Description

Technical Field

[0001] This utility model relates to the field of cleaning devices, specifically a single-spray cleaning device for high-temperature resistant filter bags. Background Technology

[0002] High-temperature resistant filter bags, also known as high-temperature resistant cloth bags, are a type of filter media specifically designed for high-temperature environments. They are commonly used for gas purification and particulate matter collection in industrial processes and are widely applied in waste gas treatment systems in industries such as cement, metallurgy, chemical, and waste incineration.

[0003] After high-temperature resistant filter bags have been used, they can still be used after cleaning and repair, provided that their strength, air permeability, and other technical indicators meet the requirements of the operating conditions.

[0004] In existing technologies, the cleaning of cloth bags is generally done by rinsing them from the inside of the bag through a water pipe. However, during use and observation, it was found that this rinsing method has the problem that when the water flow intensity is too high, the high-speed water flow will impact the surface of the cloth bag, which can easily cause the surface fibers of the cloth bag to break and tear.

[0005] Therefore, a single-spray cleaning device for high-temperature resistant filter bags is proposed to address the above problems. Utility Model Content

[0010] Preferably, the surface of the skateboard is fixed with multiple reinforcing ribs; the reinforcing ribs are arranged in a circumferential array; by setting the reinforcing ribs, the reinforcing ribs can improve the tear resistance of the airbag surface on the one hand, and increase the contact area between the airbag and the bag on the other hand, so as to guide the inflation pressure evenly from the edge of the bag to the entire contact surface, and reduce the dead corners of wrinkles caused by uneven local fiber stretching of the bag.

[0011] Preferably, a sealing strip is fixed to the end of the box body; the sealing strip is located at the connection between the slide plate and the box body; by setting the sealing strip, the wastewater generated by the rinsing component when rinsing the cloth bag will be intercepted by the sealing effect of the sealing strip when it enters the box body through the gap between the box body and the slide plate, reducing the amount of waste liquid entering the box body and reducing the workload of its maintenance.

[0024] 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.

[0025] Specific implementation examples are given below.

[0026] Please see Figures 1 to 5As shown in the figure, a single-spray cleaning device for high-temperature resistant filter bags according to an embodiment of the present invention includes a housing 1, on which a cabinet door 12 is slidably fitted; a rinsing assembly is provided on one side of the housing 1; multiple sets of back pressure assemblies are provided inside the housing 1; a power assembly for controlling the back pressure assemblies is provided on the top of the housing 1; a drainage assembly is provided on one side of the housing 1; the rinsing assembly includes a motor 13; the motor 13 is fixedly installed on one side of the housing 1; a water outlet pipe 14 is provided on one side of the motor 13; the water outlet pipe 14 and the housing 1 are through-connected and rotatably connected; multiple sets of water outlet holes 18 are opened on the surface of the water outlet pipe 14 located inside the housing 1; a belt is sleeved between the water outlet pipe 14 and the output end of the motor 13; the water outlet pipe 14 is a single-spray cleaning device for high-temperature resistant filter bags according to an embodiment of the present invention. A water pipe 14 is connected to an inlet pipe 15 on one side, and the outlet pipe 14 and the inlet pipe 15 are rotatably connected; the inlet pipe 15 and the housing 1 are fixedly connected by bolts; a fixing seat 151 is fixedly connected to the inner wall of the housing 1; the fixing seat 151 and the outlet pipe 14 are rotatably connected; a cloth bag 17 and a clamp 16 are sequentially provided on the outer wall of the fixing seat 151, and the clamp 16 is used to fix the cloth bag 17; the back pressure assembly and the water outlet 18 are correspondingly arranged; the back pressure assembly includes symmetrically arranged box bodies 19; a pair of box bodies 19 are fixedly connected to the top and bottom of the inner wall of the housing 1 respectively; a sliding plate 110 is slidably connected to the inner wall of the box body 19; a spring is fixedly installed between one end of the sliding plate 110 and the box body 19; the sliding plate 110... An airbag 111 is fixed to the other end of the bag 10; the airbag 111 is located on one side of the cloth bag 17; during operation, the cabinet door 12 can be opened and the cloth bag 17 can be placed on the outside of the water outlet pipe 14 and the fixing seat 151. Then, the cloth bag 17 can be fixed to the surface of the fixing seat 151 by the clamp 16 and bolts. Then, the power component can be activated to control the back pressure component to be in the deployed state, that is, the slide plate 110 will slide along the box body 19 and bring the airbag 111 closer to the water outlet pipe 14 until the airbag 111 can contact the outer wall of the cloth bag 17. At this time, the rinsing component will also be in the open state, that is, the motor 13 will start, and the water inlet pipe 15 will be connected to an external water pump so that the cleaning water will enter the water outlet pipe 14 through the water inlet pipe 15 and be sprayed out through the water outlet hole 18. The cleaning water will spray from the inner wall of the cloth bag 17. During rinsing, the water outlet 14 rotates along with the water outlet 18 under the drive of the belt, allowing cleaning water to be sprayed out from the cloth bag 17. The cloth bag 17 expands under the impact of water pressure and contacts the air bag 111 to compress it. The air bag 111 applies pressure to the surface of the cloth bag 17 under the action of internal air pressure to counteract the impact of the water flow inside, ensuring that the cloth bag 17 will not tear due to excessive water flow impact. The wastewater after cleaning can be discharged by opening the drain assembly. Finally, the back pressure assembly can be contracted by the power assembly to remove the cleaned cloth bag 17. It is worth mentioning that the sliding range of the slide plate 110 in the box 19 is limited, so it will not slide out of the box 19.By incorporating a counter-pressure component, a reverse compressive force can be provided at the point where water flow impacts the surface of the filter bag 17, compensating for and reducing the tearing effect on the surface of the filter bag 17, thus preventing the filter bag 17 from being damaged or torn due to excessive water flow.

[0027] Please see Figure 2 and Figure 3 As shown, the power assembly includes a winch 2; the winch 2 is fixedly installed on the top of the housing 1; a rotating shaft 22 is fixedly connected to the output end of the winch 2; multiple main steel cables 23 are fixedly connected to the surface of the rotating shaft 22, and the main steel cables 23 and the counter-pressure assembly are correspondingly arranged; a pair of steel cable branch cables 24 are fixedly connected to the end of each main steel cable 23; a connecting rod 25 is fixedly connected to the surface of the slide plate 110; the connecting rod 25 and the ends of the steel cable branch cables 24 are fixedly connected; when it is necessary to control the counter-pressure assembly, the rotating shaft 22 can be controlled by starting the winch 2. When the shaft 22 rotates, it pulls or releases all the main steel cables 23. Under the pulling action of the shaft 22, the main steel cables 23 pull or release the connecting rods 25 through the branch steel cables 24. This causes the slide plate 110 to move vertically along the box 19 as the tension at the connecting rods 25 changes, thus achieving synchronous control of all the counter-pressure components. By setting up a power component, all the counter-pressure components can be synchronously controlled in a unified manner, improving the automation level of the device's control over the counter-pressure components and reducing the workload required for the device to operate them.

[0028] Please see Figure 3 and Figure 4 As shown, multiple reinforcing ribs 3 are fixed to the surface of the slide plate 110; the reinforcing ribs 3 are arranged in a circumferential array; by setting the reinforcing ribs 3, the reinforcing ribs 3 can improve the tear resistance of the airbag 111 surface on the one hand, and increase the contact area between the airbag 111 and the cloth bag 17 on the other hand, so as to guide the inflation pressure evenly from the edge of the cloth bag 17 to the entire contact surface, and reduce the wrinkles and dead corners caused by uneven local fiber stretching of the cloth bag 17.

[0029] Please see Figure 4 As shown, a sealing strip 4 is fixedly connected to the end of the box body 19; the sealing strip 4 is located at the connection between the slide plate 110 and the box body 19; by setting the sealing strip 4, the wastewater generated when the rinsing assembly rinses the cloth bag 17 will be intercepted by the sealing effect of the sealing strip 4 when it enters the box body 19 through the gap between the box body 19 and the slide plate 110, thereby reducing the waste liquid entering the box body 19 and reducing the workload of its maintenance.

[0030] Please see Figure 1 and Figure 2As shown, the drainage assembly includes a drain pipe 52; the drain pipe 52 and the housing 1 are connected; the inner wall of the slide plate 110 is fixed with a support platform 5, and the corners of the support platform 5 are inclined; the back pressure assembly is located above the support platform 5; when drainage is required, the wastewater in the housing 1 can be discharged by opening the valve at the drain pipe 52. In addition, the wastewater generated when the rinsing assembly rinses the cloth bag 17 will accumulate at the bottom of the housing 1, and the other part will accumulate on the surface of the support platform 5. The surface of the support platform 5 can be sloped in all directions, and by tilting the edge of the support platform 5, it is easy to discharge the wastewater on the support platform 5, so as to reduce the corrosive effect of this wastewater on the internal components of the back pressure assembly. It is worth mentioning that after rinsing the cloth bag 17, the inside of the housing 1 can also be dehumidified by a hot air supply device to increase the service life of the internal components. Since hot air dehumidification is a conventional method, it will not be described in detail.

[0031] Please see Figure 1 As shown, the cabinet door 12 has an observation window 6 on its surface. When the rinsing assembly rinses the cloth bag 17, the cabinet door 12 should be closed. At this time, the cleaning status of the cloth bag 17 inside the cabinet 1 can be observed through the observation window 6, which helps the staff to judge when to remove the cloth bag 17.

[0032] Working principle: Open cabinet door 12 and place cloth bag 17 on the outside of water outlet pipe 14 and fixing base 151. Then, use clamps 16 and bolts to fix cloth bag 17 to the surface of fixing base 151. Then, start the power component to control the back pressure component to be in the deployed state, that is, the slide plate 110 will slide along the box body 19 and bring the air bag 111 closer to the water outlet pipe 14 until the air bag 111 can contact the outer wall of cloth bag 17. At this time, the rinsing component will also be in the activated state, that is, the motor 13 will start, and the water inlet pipe 15 will be connected to the water pump, so that the cleaning water will enter the water outlet pipe 14 through the water inlet pipe 15 and be sprayed out through the water outlet 18. The cleaning water will rinse the inner wall of cloth bag 17. At the same time, the water outlet pipe 14 will be driven by the belt and the water outlet 18 will be sprayed out. The components rotate together, allowing cleaning water to be sprayed out from the bag 17. The bag 17 expands under the impact of water pressure and comes into contact with and compresses the airbag 111. The airbag 111, under its internal air pressure, applies pressure to the surface of the bag 17 to counteract the impact of the water flow, ensuring that the bag 17 does not tear due to excessive water pressure. The wastewater after cleaning can be discharged by opening the drain assembly. Finally, the back pressure assembly can be contracted by the power assembly to remove the cleaned bag 17. It is worth noting that the sliding range of the slide plate 110 within the housing 19 is limited, so it will not slide out of the housing 19. When control of the back pressure assembly is needed, the winch 2 can be started to control the rotating shaft 22. Rotation of the shaft 22 pulls or releases all the main steel cables 23. Under the pulling action of the shaft 22, the main steel cables 23, through the branch steel cables 24, pull or release the connecting rods 25, causing the slide plate 110 to move vertically along the box 19 according to the change in tension at the connecting rods 25, thus achieving synchronous control of all counter-pressure components. By setting a sealing strip 4, wastewater generated during rinsing of the filter bag 17 is intercepted when it enters the box 19 through the gap between the box 19 and the slide plate 110, reducing the amount of waste liquid entering the box 19 and lessening the workload of maintenance. When drainage is needed, the wastewater in the box 1 can be discharged by opening the valve at the drain pipe 52. When the rinsing assembly rinses the filter bag 17, some of the wastewater will accumulate at the bottom of the housing 1, while the rest will accumulate on the surface of the support platform 5. The surface of the support platform 5 can be sloped in all directions, and by tilting the edges of the support platform 5, it is easy for the wastewater on the support platform 5 to drain, thereby reducing the corrosive effect of this wastewater on the internal components of the counterpressure assembly. It is worth mentioning that after rinsing the filter bag 17, the inside of the housing 1 can also be dehumidified by a hot air supply device to increase the service life of the internal components. Since hot air dehumidification is a conventional method, it will not be described in detail. When the rinsing assembly rinses the filter bag 17, the cabinet door 12 should be closed. At this time, the cleaning status of the filter bag 17 inside the housing 1 can be observed through the observation window 6, which helps the staff to judge when to remove the filter bag 17.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
