Abstract
Description
Technical Field
[0001] This utility model relates to the field of PTFE coated bag cleaning technology, and in particular to a dust cleaning device for the surface of PTFE coated bags. Background Technology
[0002] Industrial dust collector bags, as the main filtration element in baghouse dust collectors, are widely used in flue gas treatment processes in industries such as cement, steel, chemicals, food, and power. These bags are typically made of PTFE-coated material to improve their filtration efficiency, corrosion resistance, and dust removal properties. However, during long-term operation, fine dust can still easily accumulate on the surface of the bags, affecting their air permeability and service life.
[0003] As shown in the reference case "An industrial bag dust collector that is easy to clean" (publication number CN221062028U), the easy-to-clean bag dust collector has the advantages of cleaning the dust accumulated on the inner wall of the bag, dust collection function, and easy replacement of the bag.
[0004] However, existing bag filter components can shake off and clean the dust from the bag by vibrating it. But when the dust particles are fine and have strong adhesion, vibration alone is not enough to completely clean the dust from the inner surface of the bag, which can easily cause dust accumulation and affect the ventilation resistance of the dust collector.
[0005] Therefore, a surface dust cleaning device for PTFE-coated bags is proposed to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a surface dust cleaning device for PTFE-coated filter bags to solve the above-mentioned problems. It improves the existing filter bag dust removal components. Although the dust in the filter bags can be shaken off and cleaned by vibrating the filter bags, when the dust particles are fine and have strong adhesion, it is difficult to completely clean the dust on the inner wall surface of the filter bags by vibration alone. This can easily cause dust accumulation and affect the ventilation resistance of the dust collector.
[0007] This utility model achieves the above-mentioned objective through the following technical solution: a surface dust cleaning device for PTFE coated bags, comprising: a dust collection box, with an air inlet pipe and an air outlet pipe fixedly installed on both sides of the dust collection box, and a cloth bag disposed inside the dust collection box; a dust cleaning mechanism, wherein the dust cleaning mechanism for cleaning the cloth bag is disposed on one side of the cloth bag; wherein the dust cleaning mechanism includes a support frame disposed inside the dust collection box, the cloth bag being fitted onto the outside of the support frame, a cleaning component disposed on one side of the cloth bag, and a shaking component disposed on the top of the cloth bag. During use, the cleaning component can extend into the inside of the cloth bag and the support frame when cleaning is required, brushing and cleaning the inner side of the cloth bag. During cleaning, the shaking component can rotate and shake the cloth bag and the support frame to assist in the peeling and removal of dust.
[0008] Preferably, the cleaning assembly includes a movable frame disposed inside the dust collection box, a support frame rotatably mounted on one side of the movable frame, a recycling bin fixedly mounted at the bottom of the dust collection box, an electric telescopic rod fixedly mounted at the bottom of the recycling bin, and multiple cleaning brushes fixedly mounted on the outer side of the output end of the electric telescopic rod. The electric telescopic rod and the multiple cleaning brushes are located inside the support frame and the filter bag. When cleaning is required, one end of the electric telescopic rod is driven to extend through the movable frame and enter the interior of the support frame. Through the contact friction between the cleaning brushes and the inner wall of the filter bag, the dust on its surface is repeatedly brushed and cleaned. At the same time, the filter bag is slightly shaken by the shaking assembly, which helps to accelerate the dust removal and downward fall, and finally fall into the recycling bin below for centralized collection and processing.
[0009] Preferably, a guide ring is fixedly installed inside the movable frame, and a baffle is fixedly installed at the top of the electric telescopic rod. The baffle slides in contact with the guide ring. When the dust collector is in normal use, the baffle can separate the recycling bin and the recycling bin to avoid affecting the normal use of the dust collector.
[0010] Preferably, the surface of the guide ring is configured as a funnel shape, and the top cross-section of the baffle is configured as a triangular shape. When cleaning dust, the falling dust can be guided into the recycling bin through the funnel shape at the top of the guide ring.
[0011] Preferably, the shaking assembly includes an electric push rod fixedly installed inside the dust collection box. A drive plate is fixedly installed at the output end of the electric push rod. One side of the drive plate is located at the top of the support frame. A motor is fixedly installed at the top of the drive plate. The output end of the motor is fixedly connected to the support frame. During the bag cleaning process, the electric push rod can drive the drive plate to move back and forth, synchronously driving the motor and the connected support frame to shake, thereby causing the entire bag to shake slightly, which helps to accelerate the loosening and falling off of dust particles. The motor can synchronously drive the support frame and the bag it covers to rotate slowly, achieving a more uniform cleaning effect.
[0012] Preferably, the shaking component further includes a telescopic sleeve fixedly installed at the bottom of the movable frame, the other end of which is fixedly connected to the bottom wall of the dust collection box. The telescopic sleeve is used to connect the movable frame and the recycling bin to prevent dust from scattering during recycling.
[0013] Preferably, a spring is fixedly installed at the bottom of the movable frame, and the other end of the spring is fixedly connected to the dust collection box. The spring can deform when the movable frame moves, and the movable frame can be reset by the spring after cleaning.
[0014] The beneficial effects of this utility model are:
[0015] 1. The cleaning component uses a soft cleaning brush in conjunction with a telescopic motion to brush the dust on the inner wall. The shaking component is linked to the motor via an electric push rod, which causes the entire bag to shake slightly and rotate slowly, thereby improving the dust removal efficiency. Compared with the traditional high-pressure pulse jet blowing method, it is gentler and more reliable, avoiding impact damage to the PTFE film surface.
[0016] 2. During the bag cleaning process, the electric push rod can drive the drive plate to move back and forth, which in turn drives the motor and its connected support frame to shake, thus causing the entire bag to shake slightly. This helps to accelerate the loosening and falling off of dust particles. The motor can also drive the support frame and the bag it is fitted with to rotate slowly, achieving a more uniform cleaning effect. Attached Figure Description

[0022] 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 protection scope of the present utility model.
[0023] In practical implementation: such as Figure 1-4 As shown, a surface dust cleaning device for PTFE coated bags includes: a dust collection box 1, with an air inlet pipe 11 and an air outlet pipe 12 fixedly installed on both sides of the dust collection box 1, and a filter bag 2 disposed inside the dust collection box 1; a dust cleaning mechanism 3, which is disposed on one side of the filter bag 2 for cleaning the filter bag 2; wherein, the dust cleaning mechanism 3 includes a support frame 31 disposed inside the dust collection box 1, the filter bag 2 is sleeved on the outside of the support frame 31, a cleaning component 32 is disposed on one side of the filter bag 2, and a shaking component 33 is disposed on the top of the filter bag 2. In use, the cleaning component 32 can extend into the inside of the filter bag 2 and the support frame 31 when cleaning is required, and brush the inside of the filter bag 2. During cleaning, the shaking component 33 can rotate and shake the filter bag 2 and the support frame 31 to assist in the peeling and falling off of dust.
[0024] Industrial dust removal equipment typically consists of a dust collection box 1, filter bags 2, inlet and outlet pipes, and a frame support. The cleaning component 32 uses a soft cleaning brush 324 in conjunction with a telescopic motion to brush the dust on the inner wall. The shaking component 33 is linked to the motor 333 via an electric push rod 331, causing the filter bag 2 to vibrate slightly and rotate slowly, thereby improving the dust removal efficiency. Compared with the traditional high-pressure pulse jet cleaning method, it is gentler and more reliable, avoiding impact damage to the PTFE coating surface. Moreover, each component operates without interfering with the normal airflow path and dust removal rhythm, thus not affecting the original function of the dust removal system.
[0025] like Figure 2 , Figure 3 and Figure 4As shown, the cleaning component 32 includes a movable frame 321 disposed inside the dust collection box 1, a support frame 31 rotatably mounted on one side of the movable frame 321, a recycling bin 322 fixedly mounted at the bottom of the dust collection box 1, an electric telescopic rod 323 fixedly mounted at the bottom of the recycling bin 322, and multiple cleaning soft brushes 324 fixedly mounted on the outer side of the output end of the electric telescopic rod 323. The electric telescopic rod 323 and the multiple cleaning soft brushes 324 are located inside the support frame 31 and the cloth bag 2. When cleaning is required, the electric telescopic rod 323 is driven to extend one end through the movable frame 321 and enter the interior of the support frame 31. Through the contact friction between the cleaning soft brushes 324 and the inner wall of the cloth bag 2, the dust on its surface is repeatedly brushed and cleaned. At the same time, the cloth bag 2 is slightly shaken under the action of the shaking component 33, which helps to accelerate the dust peeling and fall downwards, and finally fall into the recycling bin 322 below for centralized collection and processing.
[0026] A guide ring 326 is fixedly installed inside the movable frame 321, and a baffle plate 325 is fixedly installed at the top of the electric telescopic rod 323. The baffle plate 325 slides in contact with the guide ring 326. When the dust collector 1 is in normal use, the baffle plate 325 can separate the recovery bin 322 and the recovery bin 322 to avoid affecting the normal use of the dust collector 1. The surface of the guide ring 326 is set in a funnel shape, and the top cross section of the baffle plate 325 is set in a triangular shape. When cleaning dust, the falling dust can be guided into the recovery bin 322 through the funnel shape at the top of the guide ring 326.
[0027] like Figure 2 , Figure 3 and Figure 4 As shown, the shaking assembly 33 includes an electric push rod 331 fixedly installed inside the dust collection box 1. A drive plate 332 is fixedly installed at the output end of the electric push rod 331. One side of the drive plate 332 is located on the top of the support frame 31. A motor 333 is fixedly installed on the top of the drive plate 332. The output end of the motor 333 is fixedly connected to the support frame 31. During the cleaning process of the filter bag 2, the electric push rod 331 can drive the drive plate 332 to move back and forth, thereby causing the drive plate 332 to drive the motor 333 and the connected support frame 31 to shake, thus causing the filter bag 2 to shake slightly. The shaking helps to loosen and remove dust particles. At the same time, during the cleaning process, the motor 333 can synchronously drive the support frame 31 and the cloth bag 2 it is fitted with to rotate slowly, so that multiple cleaning brushes 324 can cover multiple areas of the inner wall of the cloth bag 2 in sequence, achieving a more uniform cleaning effect. The shaking component 33 also includes a telescopic sleeve 334 fixedly installed at the bottom of the movable frame 321. The other end of the telescopic sleeve 334 is fixedly connected to the bottom wall of the dust collection box 1. The telescopic sleeve 334 is used to connect the movable frame 321 and the recycling bin 322 to prevent dust from scattering during recycling.
[0028] A spring 335 is fixedly installed at the bottom of the movable frame 321. The other end of the spring 335 is fixedly connected to the dust collection box 1. The spring 335 can deform when the movable frame 321 moves, and after cleaning, the movable frame 321 is reset by the spring 335.
[0029] In use, when cleaning is required, the electric telescopic rod 323 extends one end through the movable frame 321 and enters the interior of the support frame 31. The cleaning brush 324 contacts and rubs against the inner wall of the bag 2, repeatedly brushing away dust. During the cleaning process, the electric push rod 331 drives the drive plate 332 to move back and forth, causing the drive plate 332 to drive the motor 333 and its connected support frame 31 to shake. This, in turn, causes the bag 2 to vibrate slightly, helping to accelerate the cleaning of dust particles. The particles loosen and fall off. At the same time, during the cleaning process, the motor 333 can synchronously drive the support frame 31 and the cloth bag 2 it is fitted with to rotate slowly, so that multiple cleaning soft brushes 324 can cover multiple areas of the inner wall of the cloth bag 2 in sequence, achieving a more uniform cleaning effect. The telescopic sleeve 334 is used to connect the movable frame 321 and the recycling bin 322 to prevent dust from scattering during recycling. The spring 335 can deform when the movable frame 321 moves, and after cleaning, the movable frame 321 is reset by the spring 335.
[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
