Description

Technical Field

[0001] This utility model relates to the technical field of baghouse dust collectors, and in particular to the dust collector bag cleaning reinforcement rod. Background Technology

[0002] When a baghouse dust collector is in operation, dust-laden gas enters the filter bag chamber through the inlet duct. Due to the inertia, diffusion, blocking, hooking, and electrostatic effects of the filter fibers and fabric, dust is trapped on the surface of the filter bags. Especially under conditions where the flue gas is warm, the phenomenon of dust caking and crusting on the outer surface of the filter bags is very serious. The dust collector's own cleaning system has difficulty removing this dust, causing the system to malfunction and become unusable. In response to this situation, our company has tested and developed a dust collector bag cleaning air cannon. In order to deal with filter bags of 4 meters and above, this device was invented to assist the bag cleaning air cannon in providing dust removal services.

[0003] Existing baghouse dust collectors, such as the pulse jet baghouse dust collector disclosed in utility model patent application number 202221905557.6, mainly include a dust collector shell and a detachable ash hopper with an opening at the top. The detachable ash hopper is installed at the bottom of the dust collector shell. Two connecting parts are installed between the dust collector shell and the detachable ash hopper. An air inlet pipe is opened on one side wall of the dust collector shell. In use, the air inlet pipe is connected to the dust gas to carry out subsequent dust removal work. The dust gas is transported into the dust collector shell through the air inlet pipe and comes into contact with the blocking parts to avoid the dust gas directly hitting the dust filter bags and causing damage. The blocking parts can block the gas and flexibly absorb larger particulate matter.

[0004] However, when cleaning dust collector bags of 4 meters or more, the pulse cleaning system built into the dust collector is mostly ineffective, especially when the dust is sticking to the bags in the working conditions, making it difficult to peel the dust from the bottom of the bag off the surface of the filter material. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a dust collector bag cleaning reinforcement rod that not only facilitates the cleaning of dust collector bags of 4 meters and above, but also improves the cleaning efficiency through its convenient operation design. Furthermore, it makes it easier to peel the dust off the filter material surface at the bottom of the bag, resulting in a more ideal cleaning effect.

[0006] This utility model discloses a dust collector bag cleaning reinforcement rod, including a positioning isolation plate; it also includes a height adjustment mechanism, a flow guiding and ejecting mechanism, and an extension mechanism. The height adjustment mechanism is installed on the positioning isolation plate and adjusts the distance between the bag cleaning air cannon and the flow guiding and ejecting mechanism. The flow guiding and ejecting mechanism is installed on the height adjustment mechanism and guides the airflow. The extension mechanism is installed on the flow guiding and ejecting mechanism and guides the airflow to the lower end of the bag. The length of the extension mechanism is adjusted according to the length of the bag to accommodate bags of different lengths. Then, the height of the flow guiding and ejecting mechanism and the bottom outlet of the bag cleaning air cannon are adjusted. The positioning isolation plate matches the size of the bag keel mouth ring and the bag cleaning air cannon cage seat. The bag cleaning air cannon sprays compressed air, which is transported to the lower end of the dust collector bag through the flow guiding and ejecting mechanism and the extension mechanism, peeling the dust off the filter material surface at the lower end of the bag, making the cleaning effect more ideal.

[0007] Preferably, the bottom end of the positioning isolation plate abuts against the bag keel opening ring, and the outer diameter of the positioning isolation plate is slightly smaller than the upper port size of the dust collector bag; the bottom end of the positioning isolation plate abuts against the bag keel opening ring, and the positioning isolation plate and the bag cleaning air cannon cage seat cooperate for positioning.

[0008] Preferably, the height adjustment mechanism includes a double external thread connecting pipe, a first internal thread clamp, and a single thread head. The double external thread connecting pipe is installed on the positioning isolation plate. The bottom end of the first internal thread clamp is threaded to the top end of the double external thread connecting pipe, and the bottom end of the single thread head is threaded to the top end of the first internal thread clamp. The distance between the double external thread connecting pipe and the single thread head can be easily adjusted through the first internal thread clamp, thereby adjusting the distance between the flow guiding and ejecting mechanism and the air outlet of the bag cleaning air cannon.

[0009] Preferably, the flow guiding and ejecting mechanism includes a variable diameter, the bottom end of which is internally connected to the top end of the monofilament head, and the top end of the variable diameter is directly opposite the air outlet of the bag cleaning air cannon; the variable diameter can guide the gas ejected from the bag cleaning air cannon, and by adjusting the distance between the variable diameter and the air outlet at the bottom end of the bag cleaning air cannon, it is convenient to meet the cleaning needs of filter bags of various sizes under various working conditions.

[0010] Preferably, the extension mechanism includes multiple sets of second inner-coil clamps and multiple sets of extension rods. The top end of the first set of extension rods is threaded to the bottom end of the double-threaded connecting pipe, and the top end of the first set of second inner-coil clamps is threaded to the bottom end of the first set of extension rods. The remaining sets of second inner-coil clamps and extension rods are connected in the same manner. According to the length of the dust collector bag, the operator selects an appropriate number of sets of second inner-coil clamps and extension rods to connect. Compressed air is conveyed through multiple sets of second inner-coil clamps to the lower end of the bag. The compressed air peels the dust from the bottom of the bag off the surface of the filter material, while simultaneously creating a negative pressure zone that drives the surrounding space to generate airflow to assist in dust removal.

[0011] Preferably, the first set of extension rods and the double external thread connecting pipe can also be connected by a rubber hose; the rubber hose connects the first set of extension rods and the inside of the double external thread connecting pipe, reducing the use of the second internal clamp and saving production costs.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the length of the extension mechanism is adjusted according to the length of the filter bag to easily adapt to filter bags of different lengths. Then, the height of the guide jet mechanism and the bottom outlet of the filter bag cleaning air cannon are adjusted by using the guide jet mechanism. The size of the filter bag keel mouth ring and the filter bag cleaning air cannon cage seat are matched by the positioning isolation plate. The filter bag cleaning air cannon sprays compressed air. The compressed air is transported to the lower end of the dust collector bag through the guide jet mechanism and the extension mechanism, which peels the dust off the filter material surface at the lower end of the filter bag, making the cleaning effect more ideal.
