Background Art

[0002] In order to improve the efficiency of filtration, a back-blowing bag dust collector is used. The main principle is that the bag dust collector uses reverse back-blowing airflow to clean the filter bags. The back-blowing cleaning method uses reverse airflow and reverse pressure to compress the filter bags into a star-shaped cross-section and make them vibrate to shake off the deposited dust layer.

[0003] In order to ensure the continuous operation of the dust collector, the chamber working system is often adopted. Therefore, the back-blowing cleaning method is not only used for textile filter cloth, but also for glass fiber filter cloth. The back-blowing bag dust collector is composed of a dust collector box, frame, ash hopper, valve, air duct, differential pressure system, ladder platform and electronic control system. It is a form of reverse airflow cleaning, but the cleaning effect of this cleaning method is relatively weak, the vibration is not violent, and the damage to the filter cloth is less than that of vibration cleaning and pulse cleaning, and the filtration efficiency is also lower.

DETAILED DESCRIPTION

[0033] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0034] like Figures 1-6 As shown, the PTFE dust filter bag structure based on the chambered back-flushing dust collector provided in this embodiment includes a dust collector housing 1, a buffer connection chamber 2 is connected to the top of the dust collector housing 1, a plurality of evenly distributed filter bag supports 4 are connected to the bottom of the buffer connection chamber 2, a clean air chamber 3 is connected to the top of the buffer connection chamber 2, the filter bag supports 4 are in communication with the clean air chamber 3, an electric telescopic rod assembly 6 is fixedly provided inside the filter bag support 4, and a filter bag 5 is fixedly provided on the outer side of the filter bag support 4, wherein when the electric telescopic rod assembly 6 is braked, the filter bag support 4 moves up and down;

[0035] In order to ensure the continuous operation of the dust collector, the chamber working system is often used. Therefore, the back-blowing cleaning method is not only used for textile filter cloth, but also for glass fiber filter cloth. The back-blowing bag dust collector is composed of a dust collector box, frame, ash hopper, valve, air duct, differential pressure system, ladder platform and electronic control system. It is a form of reverse airflow cleaning, but the cleaning effect of this cleaning method is relatively weak, the vibration is not violent, and the damage to the filter cloth is less than that of vibration cleaning and pulse cleaning. In the back-blowing cleaning method, the reverse airflow and reverse pressure are used to clean the filter cloth. In the process of the bag being compressed into a star-shaped cross-section and vibrating to shake off the deposited dust layer, the electric telescopic rod assembly 6 is braked up and down, so that the second spring 8 on the telescopic rod base 601 drives the filter bag bottom plate 401 to vibrate, and the first spring 7 on the telescopic rod output rod 602 drives the filter bag top plate 402 to vibrate, thereby driving the entire movement of 4, that is, driving the filter bag 5 to vibrate, thereby increasing the frequency and amplitude of the vibration of the filter bag support 4, greatly improving the dust shaking-off rate and improving the filtration efficiency;

[0036] The filter bag support 4 includes a filter bag bottom plate 401 and a filter bag top plate 402. The electric telescopic rod assembly 6 is vertically arranged between the filter bag bottom plate 401 and the filter bag top plate 402. The electric telescopic rod assembly 6 is arranged between the filter bag support 4. Therefore, the vibration of the electric telescopic rod assembly 6 can drive the vibration of the filter bag bottom plate 401 and the filter bag top plate 402 respectively. During the process of large vibration, the vibration of the entire filter bag support 4 is driven. At the same time, with the back-blowing, the efficiency of shaking off can be greatly improved.

[0037] At the same time, the electric telescopic rod assembly 6 includes a telescopic rod base 601 and a telescopic rod output rod 602. The bottom end of the telescopic rod base 601 is fixedly connected to the filter bag bottom plate 401 through the second spring 8. The telescopic rod output rod 602 at the output end of the electric telescopic rod assembly 6 is fixedly connected to the filter bag top plate 402 through the first spring 7. A number of ventilation holes 403 are provided on the filter bag top plate 402. The telescopic rod base 601 is connected to the filter bag bottom plate 401 through the second spring 8. The telescopic rod output rod 602 is connected to the filter bag top plate 402 through the first spring 7, so that the filter bag support 4 can become a whole, which can drive the overall vibration of the filter bag support 4. At the same time, the purified air can enter the interior of the filter bag support 4 through the filter bag 5, and then be discharged through the ventilation holes 403. The structure is simple and greatly improves the filtration efficiency.

[0038] Further, such as Figure 4 As shown, the filter bag 5 is fixed to the outer surface of the filter bag support 4 by screws, wherein the lower end of the filter bag 5 is fixedly connected to the filter bag bottom plate 401, and the upper end of the filter bag 5 is fixedly connected to the filter bag top plate 402. The filter bag 5 is fixed to the filter bag support 4 by screws to prevent the filter bag support 4 from causing the filter bag 5 to fall off during shaking, thereby improving the stability of the filter bag 5 and thus improving the overall stability of the filter bag support 4. A filter bin 105 is provided inside the dust collector housing 1, and the filter bag support 4 is arranged inside the filter bin 105. A dust-laden air inlet 102 is connected to one side of the dust collector housing 1, and the dust-laden air inlet 102 is connected to the filter bin 105, which is consistent with the traditional mechanism. The mutual communication improves the flow rate of the airflow, increases the scope of use, and has good applicability.

[0039] Furthermore, Figure 2 As shown, the clean air chamber 3 is connected to a clean air outlet 301 and a back-blowing air inlet 302, and a back-blowing air blower is provided inside the clean air chamber 3. The back-blowing air inlet 302 is connected to the filter bin 105 through the back-blowing air blower, and the clean air outlet 301 is connected to the filter bin 105. The back-blowing air blower is provided inside the clean air chamber 3, and can directly discharge air into the inside of the filter bin 105 to cause vibration of the filter bag support 4, and at the same time can improve the efficiency of backblowing.

[0040] In addition, the upper end of the dust collector housing 1 is connected to a housing connection base 101, and the housing connection base 101 is fixedly connected to the buffer connection chamber 2 by bolts to enhance the strength of the structure and improve the stability of the device. Figure 1 As shown, the bottom of the dust collector housing 1 is connected to a dust outlet 103, a stop valve is connected to the dust outlet 103, and the dust outlet 103 is connected to the filter chamber 105. Figure 1As shown, a visual window groove 104 is provided on the outer side of the dust collector housing 1, and a visual window 9 is fixedly provided inside the visual window groove 104. The situation inside the filter bin 105 can be directly observed through the visual window 9 on the visual window groove 104, which facilitates observation and improves the convenience of use.

[0041] like Figures 1-6 As shown, the installation method of the PTFE dust filter bag structure based on the chamber back-blowing dust collector provided in this embodiment includes the following steps:

[0042] Step 1: Connect the telescopic rod: Install the second spring 8 on the bottom of the telescopic rod base 601 and the first spring 7 on the top of the telescopic rod output rod 602;

[0043] Step 2: Install the fixing plate: Connect the filter bag bottom plate 401 to the bottom of the second spring 8 and connect the filter bag top plate 402 to the top of the first spring 7;

[0044] Step 3: Filter bag installation: Fix one end of the filter bag 5 to the filter bag bottom plate 401, and then fix the other end of the filter bag 5 to the filter bag top plate 402;

[0045] Step 4: Component Fixing: Install the fixed filter bag 5 on the buffer connection chamber 2, and then fix the buffer connection chamber 2 on the housing connection seat 101 of the dust collector housing 1;

[0046] Step 5: Complete the installation: Connect the dust-laden air inlet 102, the clean air outlet 301 and the back-blowing air inlet 302 respectively. The structure is simple and can be installed on the basis of the original back-blowing bag dust collector, which greatly improves the installation efficiency and the scope of use, and can also greatly improve the filtration efficiency.
