Description

Technical Field

[0001] This utility model relates to the field of shock device technology, and in particular to a pulse-type shock device. Background Technology

[0002] The pulse jet baghouse dust collector is a new type of high-efficiency pulse jet baghouse dust collector that is an improvement on the traditional baghouse dust collector. To further improve the pulse jet baghouse dust collector, the modified version retains its advantages such as high purification efficiency, large gas handling capacity, stable performance, convenient operation, long filter bag life, and low maintenance workload.

[0003] In existing pulse jet baghouse dust collectors, dust removal is achieved by applying pressure to the long filter bag through a pulse system, causing the bag to expand and the dust on the surface of the bag to fall off. However, when the bag expands, the middle part floats more and the dust removal effect is better, but the lower part of the bag floats less and cannot achieve a good dust removal effect. Therefore, it is necessary to design a pulse jet vibrator to solve the above problems.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.

[0029] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a pulse-type shocker, comprising:

[0031] Air box 1, main pulse tube 2 is fixedly installed on air box 1, and pulse vibration mechanism is installed on main pulse tube 2. It should be noted that the filter bag 5 is dusted by pulse action. The pulse vibration mechanism can perform pulse vibration treatment on the lower part of the filter bag 5, and perform auxiliary dust removal on the lower part of the filter bag 5, so as to improve the overall dust removal effect of the filter bag 5.

[0032] The pulse shock mechanism includes an auxiliary pulse tube 3, a piston 6, a hollow part 7, a counterweight disc 8, a side rod 9, a moving rod 10, a striking ball 11, and a hinge 13;

[0033] The auxiliary pulse tube 3 is fixedly installed on the main pulse tube 2. The top of the piston 6 is fixedly connected to the counterweight disc 8. The piston 6 is slidably and sealed inside the auxiliary pulse tube 3. The top of the auxiliary pulse tube 3 is fixedly connected to the hollow part 7. The moving rod 10 is slidably installed on the hollow part 7. The striking ball 11 is fixedly connected to the moving rod 10. Both the moving rod 10 and the counterweight disc 8 are fixedly provided with connecting ears 12. The hinge 13 is hingedly installed on the connecting ears 12.

[0034] With the above structure, closing solenoid valve 14 and opening solenoid valve 15 activates pulse valve 4. Compressed air in air box 1 enters auxiliary pulse pipe 3 through main pulse pipe 2 and then impacts piston 6, causing piston 6 to drive counterweight disc 8. Through the cooperation of connecting lug 12 and hinge 13, multiple moving rods 10 can drive striking ball 11 to move, causing striking ball 11 to vibrate side rod 9, thus vibrating filter bag 5 and shaking off dust at the lower end of filter bag 5, thus assisting in dust removal at the lower end of filter bag 5 and improving the overall dust removal effect of filter bag 5. Then, piston 6 moves above side hole 16, and pulse air is discharged to the outside through side hole 16. Subsequently, counterweight disc 8 moves back to its original position due to its own gravity.

[0035] Specifically, the pulse shock mechanism also includes a pulse valve 4, a solenoid valve 14, and a solenoid valve 2. The pulse valve 4 is installed on the main pulse tube 2, the solenoid valve 14 is installed on the main pulse tube 2, and the solenoid valve 2 is installed on the auxiliary pulse tube 3.

[0036] With the above structure, first open solenoid valve 14 and close solenoid valve 2 15, start pulse valve 4, and the compressed air in air box 1 enters the filter bag 5 through main pulse pipe 2, which expands the filter bag 6 and performs dust removal treatment on the filter bag 6.

[0037] Specifically, the auxiliary pulse tube 3 is internally connected to the main pulse tube 2. The auxiliary pulse tube 3 has a side hole 16. It should be noted that the side hole 16 is designed to facilitate the discharge of pulsed air after it impacts the piston 6.

[0038] Specifically, a filter bag 5 is installed on the main pulse tube 2, and side rods 9 are fixedly installed on the filter bag 5. There are multiple side rods 9, and the multiple side rods 9 are arranged in a ring with equal intervals. It should be noted that the filter bag 5 is subjected to dust removal by shaking the side rods 9.

[0039] Specifically, the hollow component 7 has multiple moving holes, and the moving rod 10 is slidably installed in the moving holes. It should be noted that this allows the moving rod 10 to move stably in the lateral direction.

[0040] Specifically, the bottom of the counterweight disc 8 contacts the inner wall of the bottom of the hollow part 7. It should be noted that the counterweight disc 8 is subject to a limiting treatment.

[0041] Working principle:

[0042] S1: When the pulse vibrator is not working, solenoid valve 14 is in the open state, solenoid valve 2 is in the closed state, piston 6 is located at the bottom of auxiliary pulse tube 3, the bottom of counterweight disc 8 is in contact with the inner wall of the bottom of hollow part 7, moving rod 10 is in the initial position on hollow part 7, and striking ball 11 is not in contact with side rod 9. When it is necessary to remove dust from filter bag 5, pulse valve 4 is activated, and compressed air in air box 1 enters filter bag 5 through main pulse tube 2, causing filter bag 5 to expand, thereby shaking off surface dust and achieving preliminary dust removal from filter bag 5.

[0043] S2: After the main pulse tube 2 removes dust from the filter bag 5, close the solenoid valve 14, open the solenoid valve 2 15, and start the pulse valve 4 again. At this time, the compressed air in the air box 1 enters the auxiliary pulse tube 3 through the main pulse tube 2. Since the piston 6 is slidably sealed in the auxiliary pulse tube 3 and the top of the piston 6 is fixedly connected to the counterweight disc 8, the compressed air impacts the piston 6, causing it to drive the counterweight disc 8 to move upward. As the piston 6 and the counterweight disc 8 rise, through the cooperation of the connecting ear 12 and the hinge 13, multiple moving rods 10 slide in the moving holes on the hollow part 7, thereby driving the striking ball 11 to move. Multiple side rods 9 are arranged in a ring with equal intervals on the filter bag 5. When the striking ball 11 moves to a certain position, it will vibrate the side rods 9. After the side rods 9 are vibrated, they will transmit the vibration to the filter bag 5, causing the dust at the lower end of the filter bag 5 to fall off, thus achieving auxiliary dust removal at the lower end of the filter bag 5, thereby improving the overall dust removal effect of the filter bag 5.

[0044] S3: When the piston 6 rises above the side hole 16, the pulse air is discharged to the outside through the side hole 16. At this time, due to the loss of the support of compressed air, the counterweight disc 8 begins to move downward due to its own weight, which drives the piston 6 to move downward back to its original position, preparing for the next shock action.

[0045] The pulse-type shock absorber provided by this utility model has been described in detail above. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
