Description

Technical Field

[0001] This utility model relates to the field of vibration device technology, specifically a vibration device used in a bag filter dust collector. Background Technology

[0002] Baghouse dust collectors are a type of high-efficiency dust removal equipment, widely used in dust control in industrial production. Their core working principle is to filter dust-laden gas through filter bags, causing the dust to adhere to the surface of the filter bags, thereby achieving gas-solid separation.

[0003] For example, the patent with announcement number CN204219936U (a bag filter): includes a shell and a dust filtration device. The dust filtration device includes several frames and several filter bags for dust filtration, which are respectively fitted outside the frames. The frames are all fixedly connected to a tube sheet provided inside the shell. At the end of the frame away from the tube sheet, a baffle plate with an outer diameter equal to or greater than the outer diameter of the bottom of the filter bag is fixedly provided. A gap for air to pass through is formed between the adjacent baffle plates.

[0004] While the aforementioned existing technologies prevent the bottom of the filter bag from cracking due to prolonged impact from high-speed airflow, in large-volume baghouse dust collectors, the filter bags are generally quite long, and the pulse cleaning system is typically positioned above the filter bags. During the cleaning process, the pulse airflow is weaker in areas of the filter bag furthest from the pulse cleaning system, resulting in less vibration and deformation in these areas. This makes it difficult to reliably shake off the dust adhering to the filter bag surface, affecting the subsequent filtration efficiency. Therefore, there is an urgent market need to develop a vibration device for baghouse dust collectors to help solve these existing problems. Utility Model Content

[0005] The purpose of this invention is to provide a vibration device for use in baghouse dust collectors, in order to solve the problem mentioned in the background art that when cleaning large-volume baghouse dust collectors, the dust adhering to the surface of the bag cannot be stably shaken off, thus affecting the subsequent filtration effect of the bag.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vibration device for a bag filter, comprising a tube sheet, a filter bag disposed below the tube sheet, a through hole provided inside the tube sheet, the upper end of the filter bag extending into the through hole, an electromagnetic chuck disposed below the filter bag, a support frame disposed inside the filter bag, an iron sheet disposed inside the filter bag along the lower part of the support frame, an mounting ring groove disposed above the outer side of the through hole inside the tube sheet, a compression spring disposed inside the mounting ring groove, a lower ring plate fixedly mounted above the compression spring, an upper ring plate disposed above the lower ring plate, the upper ring plate being connected to the support frame, and the upper ring plate and the lower ring plate being fixedly connected by bolts.

A guide post is provided inside the guide post cavity, and the upper end of the guide post slides through the spring plate seat and is fixedly connected to the lower ring plate.

[0009] Preferably, a ring edge is provided between the upper ring plate and the lower ring plate, and the ring edge is sewn to the bag.

[0011] Preferably, an installation base is fixedly installed below the electromagnetic chuck, and a base plate is fixedly installed below the installation base. Fixing rods are symmetrically fixedly installed at the front end, rear end and both sides of the base plate, and the upper end of the fixing rods is fixedly connected to the perforated plate.

[0012] Preferably, the base plate has slots inside, and multiple slots are provided.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses an electromagnetic chuck to pull down the iron plate inside the filter bag when energized, causing the filter bag to move downwards and compressing the compression spring. After the power is cut off, the compression spring elastically resets, causing the filter bag to move upwards. This process is repeated, causing the filter bag to vibrate up and down.

By setting a guide column cavity and a guide column, this utility model provides guidance for the up-and-down movement of the lower ring plate, ensuring the accurate movement trajectory of the bag during vibration, avoiding irregular movement of the bag due to shaking, and increasing its practicality.

[0016] 3. This utility model provides a stable mounting platform for the electromagnetic chuck, ensuring its stability during operation. The base plate and fixing rod securely connect the electromagnetic chuck to the perforated plate, making the entire vibration device a unified whole and improving its stability.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 This utility model provides an embodiment of a vibration device for a bag filter dust collector, comprising a tube sheet 1, a filter bag 2 disposed below the tube sheet 1, a through hole 101 disposed inside the tube sheet 1, the upper end of the filter bag 2 extending into the through hole 101, an electromagnetic chuck 3 disposed below the filter bag 2, a support frame 7 disposed inside the filter bag 2, an iron sheet 8 disposed inside the filter bag 2 along the lower part of the support frame 7, an mounting ring groove 102 disposed above the outer side of the through hole 101 inside the tube sheet 1, a compression spring 11 disposed inside the mounting ring groove 102, a lower ring plate 10 fixedly mounted above the compression spring 11, an upper ring plate 9 disposed above the lower ring plate 10, the upper ring plate 9 being connected to the support frame 7, and the upper ring plate 9 being fixedly connected to the lower ring plate 10 by bolts.

[0024] When the electromagnetic chuck 3 is energized, it pulls the iron plate 8 inside the filter bag 2 downward, causing the filter bag 2 to move downward and compress the compression spring 11. After the power is turned off, the compression spring 11 elastically resets and causes the filter bag 2 to move upward. This process is repeated to make the filter bag 2 vibrate up and down. This vibration mode is not affected by the distance limitation of the pulse airflow, thus more stably shaking off the dust adhering to the surface of the filter bag, which is beneficial to the stability of the filter bag 2's filtration operation.

[0025] Furthermore, a spring plate seat 12 is fixedly installed below the compression spring 11. The spring plate seat 12 is fixedly connected to the perforated plate 1. A damping rod 13 is provided inside the compression spring 11. The damping rod 13 is a hydraulic damping rod. The upper end of the damping rod 13 is fixedly connected to the lower ring plate 10, and the lower end of the damping rod 13 is fixedly connected to the spring plate seat 12.

[0026] The spring plate seat 12 provides a stable mounting base for the compression spring 11, ensuring the stability of the compression spring during compression and reset, and preventing the spring from affecting the vibration effect due to shaking. The hydraulic damping rod 13 is used to reduce the rebound force of the compression spring 11, so that the vibration of the bag 2 is not too strong, reducing the impact damage to the bag 2 and the support frame 7 caused by excessive vibration, and improving the reliability and safety of the device operation.

[0027] Furthermore, a guide post cavity 103 is provided inside the flower plate 1 along the outer side below the mounting ring groove 102, and the guide post cavity 103 is connected to the mounting ring groove 102. A guide post 14 is provided inside the guide post cavity 103, and the upper end of the guide post 14 slides through the spring plate seat 12 and is fixedly connected to the lower ring plate 10.

[0028] The guide column 14 provides precise guidance for the up-and-down movement of the lower ring plate 10, ensuring the accurate movement trajectory of the bag 2 during vibration, avoiding irregular movement of the bag 2 due to shaking, and increasing practicality.

[0029] Furthermore, a ring edge 201 is provided between the upper ring plate 9 and the lower ring plate 10, and the ring edge 201 is sewn to the cloth bag 2.

[0030] The sewn connection makes the connection between the ring edge 201 and the bag more secure, and can withstand the large tensile force generated by the bag during vibration. This avoids the problem of the bag separating from the vibration structure due to loose connection, and increases practicality.

[0031] Furthermore, the support frame 7 includes a fixing ring 701 and a support rod 702. Multiple fixing rings 701 are provided, and four support rods 702 are provided. The four support rods 702 are fixedly installed on the outside of the fixing rings 701. The lower end of the support rod 702 is fixedly connected to the iron plate 8, and the upper end of the support rod 702 is fixedly connected to the upper ring plate 9.

[0032] The support frame, consisting of multiple fixing rings 701 and four support rods 702, can provide uniform support force for the bag 2, so that the bag 2 can maintain a good shape during vibration and avoid deformation and damage caused by uneven local force on the bag 2.

[0033] Furthermore, an installation base 4 is fixedly installed below the electromagnetic chuck 3, and a base plate 5 is fixedly installed below the installation base 4. Fixing rods 6 are symmetrically fixedly installed on the front end, rear end and both sides of the base plate 5. The upper end of the fixing rods 6 is fixedly connected to the flower plate 1. The base plate 5 has multiple slots 501 inside.

[0034] The mounting base 4 provides a stable mounting platform for the electromagnetic chuck 3, ensuring the stability of the electromagnetic chuck during operation. The base plate 5 and the fixing rod 6 firmly connect the electromagnetic chuck to the tube sheet 1, making the entire vibration device a whole and improving stability. The slot 501 reduces the accumulation of dust and impurities on the base plate 5, increasing practicality.

[0035] Working principle: When in use, the electromagnetic chuck 3 generates magnetic force after being powered on, which attracts the iron plate 8 connected to the lower part of the internal support frame 7 of the filter bag 2, causing the iron plate 8 to move the filter bag 2 downward. At the same time, the compression spring 11 installed in the annular groove 102 inside the compression plate 1 is compressed. When the electromagnetic chuck 3 is de-energized, the compression spring 11 elastically resets, causing the filter bag 2 to move upward. This process of power on and off is repeated, causing the filter bag 2 to vibrate up and down. This vibration mode is not limited by the distance of the pulse airflow and can more stably shake off the dust adhering to the surface of the filter bag, which is beneficial to the stability of the filter bag 2's filtration operation.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
