Description

Technical Field

[0001] The invention relates to the technical field of filter bag dust removal, and in particular to a high temperature resistant filter bag dust removal device. Background Art

[0002] In actual dust treatment work, bag-type dust collector is a common dust removal equipment. Dust can be isolated by filter bags. It is widely used due to its high filtering efficiency and other advantages. Multiple filter bags are used to isolate and remove dust inside. At the same time, thanks to its own pulse jet structure, dust attached to the surface of the filter bag can be blown away easily. The filter bags of current bag-type dust removal devices are not resistant to high temperatures. The service life of the filter bags at high temperatures is reduced. It is not convenient to automatically switch the filter surface of the filter bags for water cooling protection. Traditional dust removal filter bags are fixed structures, and the dust removal areas are mostly concentrated in one place, resulting in serious local blockages. It is not convenient to transport the filter bags to use dust intake backblowing for comprehensive cleaning. At the same time, it is not convenient to detect damage and leakage of the filter bags, which can easily cause dust leakage. It is not convenient to manually check the service life of the filter bags. The blocked areas on the filter bags will affect the ventilation and filtration efficiency, and it is not convenient to prompt the alarm in time. Summary of the invention

[0043] Embodiment 2, on the basis of embodiment 1, the air permeability test piece 8 comprises: a test power connection piece 801 and a pressing paddle 802, the test power connection piece 801 is provided with a circle, and the circle of test power connection pieces 801 are respectively fixedly installed on the inner side of the dust removal keel frame 101; a circle of pressing paddles 802 are fixedly installed on the inner side of the dust removal keel frame 101; a circle of test power connection pieces 801 is aligned with a circle of pressing paddles 802; the side of the pressing paddle 802 is attached to the conveying filter bag 201; the test power connection piece 801, the pressing paddle 802 and the blockage buzzer 705 are connected in series with the power supply. The use of the air permeability test piece 8 can facilitate the staff to understand the service life of the conveying filter bag 201, avoid the local blockage of the conveying filter bag 201 after long-term use without being discovered, especially for some dust impurities with grease, through the pulse nozzle 1021 and the inner The cleaning brush 502 cannot completely clean it either, and it needs to be disassembled and cleaned with auxiliary cleaning agents. The present structure can be disassembled and cleaned after detection and confirmation of blockage, avoiding tedious manual disassembly and inspection. The present structure does not need to be shut down during the detection process, which is more practical and ensures the gas filtration permeability. It is convenient to replace or clean it in time after blockage occurs. The air pump connected to the pulse nozzle 1021 is intermittently opened and closed. If there is a serious blockage in a part of the conveying filter bag 201, it is difficult to circulate air. Under the action of air pressure, the blocked part will have a large displacement outward, and the air pressure will produce a concave on one side of the pressing paddle 802, which can squeeze the pressing paddle 802 to contact the test power terminal 801, and the blockage buzzer 705 will alarm. The detection of the present structure is direct and reasonable, avoiding the blockage caused by the continuous and long-term use of the conveying filter bag 201 affecting the filtration efficiency.

[0044] The working principle of this embodiment is as follows: first, insert the upper plate 102 into the slot in the bag filter housing, and the driving motor 401 drives the driving cylinder 402 to rotate. When the spiral protrusion 403 is driven to rotate, the spiral protrusion 403 can squeeze the rubber protrusion 203 in turn. At this time, the rubber protrusion 203 is screwed to control the conveying filter bag 201 to achieve conveying; after the conveying filter bag 201 is placed inside the bag filter housing, the outer side of the conveying filter bag 201 will filter the dust with the intake air pressure, and the pulse nozzle 1021 can be opened at a fixed time. The air pump is used to supply high-pressure gas to blow from the inside of the conveying filter bag 201 to the outside, so as to blow away the dust attached to the outside of the conveying filter bag 201. Because the conveying filter bag 201 can be transported and switched inside and outside, after the outside of the conveying filter bag 201 is transported to the inside, a small amount of dust attached to the inside will be blown inwards under the action of the intake air pressure, and then the inside cleaning brush 502 is used to brush the inside of the conveying filter bag 201 to achieve reverse cleaning using the intake air pressure, thereby ensuring the comprehensive cleaning of this structure. The suction fan connected to the ash discharge pipe 1051 is turned on, and the suction fan on the ash discharge pipe 1051 is turned on. The solenoid valve can discharge a small amount of dust that is brushed off the inside of the conveying filter bag 201; if the conveying filter bag 201 is damaged, a large amount of dust will block the filter element 703. At this time, the filter element 703, under the action of air pressure, drives the sliding cover 702 to move up and compress the spring 704. At this time, the isolation pressing shaft 701 is also driven up together, and the squeezing micro switch 603 is released, and the buzzer alarm 604 can be powered on to give an alarm prompt; when the conveying filter bag 201 is being transported, when it is necessary to detect the blockage of the conveying filter bag 201, the air connected to the pulse nozzle 1021 is intermittently opened and closed. Pump, at this time, if the air pressure sprayed by the pulse nozzle 1021 acts on the inner side of the unblocked conveying filter bag 201, the conveying filter bag 201 has good fluidity, and the conveying filter bag 201 is squeezed inwardly to a lesser extent. On the contrary, if the conveying filter bag 201 is partially severely blocked and it is difficult to circulate air, under the action of air pressure, the blocked part will be outward, that is, concave near the pressing paddle 802, and the pressing paddle 802 can be squeezed, and the pressing paddle 802 will be elastically deformed, and the end will contact the test power strip 801, and the blockage buzzer 705 will alarm;

[0045] When the filter bag needs to be cooled, the water pump connected to the water pipe 302 is started to supply water, and the water enters the cooling water storage shell 301 and is discharged from another water pipe 302. When the conveying filter bag 201 is driven to move, the conveying filter bag 201 can slide on the surface of the cooling water storage shell 301 in turn to cool down.
