Description

Technical Field

[0001] The utility model relates to the technical field of bag filters, in particular to a flat bag filter. Background Technique

[0002] Bag filters are one of the more common industrial dust collectors in the prior art. Flat bag filters, also known as flat bag dust collectors, are a kind of efficient dust removal equipment and are widely used in the industrial field, especially in occasions where a large amount of dust and particulate matter need to be processed.

[0003] The working principle of a flat bag filter is mainly to filter the dust-containing gas by using filter bags (usually flat-shaped), intercept the dust particles on the surface of the filter bags, and the clean gas is discharged through the filter bags. As the dust accumulates on the filter bags, the dust collector will perform ash cleaning operations regularly to restore the filtering performance of the filter bags. The common cleaning methods include mechanical vibration, pulse jetting, etc., to ensure the cleanliness and efficient operation of the filter bags.

[0004] However, in the prior art, when ash cleaning is carried out, it will cause instant dust raising inside the entire dust collector housing. It is necessary to wait until the dust settles automatically before continuing the filtering work, otherwise it is easy to cause the dust to quickly reattach to the surface of the filter bags, which is likely to affect the overall filtering efficiency. Therefore, an improved flat bag filter is needed to solve this problem. Content of the Utility Model

[0005] The purpose of the utility model is to provide a flat bag filter to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A flat bag filter, including a housing, a dust collection bin is arranged at the lower end of the housing, a clean bin is arranged at the upper end inside the housing, an air outlet is fixedly arranged on one side inside the clean bin, a filtering mechanism for filtering dust is arranged inside the housing, the filtering mechanism includes a partition board, a fixed frame, a corrugated flexible connection bin, a fixing plate, and filter bags. A number of partition boards are evenly and fixedly arranged inside the housing, a fixed frame is fixedly arranged at the upper end between the partition boards, a corrugated flexible connection bin is fixedly arranged at the lower end of the fixed frame, a fixing plate is fixedly arranged at the lower end of the corrugated flexible connection bin, and a number of filter bags are evenly and fixedly arranged at the lower end of the fixing plate. A pulse mechanism for dust removal is arranged at the upper end of the housing.

[0007] Preferably, the pulse mechanism includes an air bag, a blowpipe, a connecting pipe, and a pulse valve. An air bag is fixedly arranged on one side of the upper end of the housing. A plurality of blowpipes are evenly and fixedly arranged between the partitions inside the housing. A connecting pipe is fixedly arranged between the blowpipe and the air bag. A pulse valve is fixedly arranged between the connecting pipe and the blowpipe. The pulse mechanism can perform pulse backblowing on the filter bag as needed. The compressed air in the air bag rushes into the housing through the blowpipe, and the instantaneous impact generated by the high-pressure air causes the dust accumulated on the outer surface of the filter cartridge to fall off from the filter cartridge and finally enter the collection bin for collection.

[0008] Preferably, a first electric push rod is fixedly arranged at the upper end of the air outlet inside the housing. A sealing plate is fixedly arranged at the movable end of the first electric push rod. When pulse dust removal backblowing is required, the air outlet should be blocked by the sealing plate to ensure the effect of pulse dust removal.

[0009] Preferably, an air inlet is fixedly arranged on one side of the housing surface. Through the air inlet, it is convenient to introduce the flue gas to be dust-removed into the housing. The flue gas will pass through the outside of the filter bag for filtration, enter the inside of the filter bag, then enter the clean bin from the inside of the filter bag, and then be discharged from the air outlet of the clean bin. The dust will gather inside the collection bin under the action of gravity and adhere to the outer surface of the filter bag.

[0010] Preferably, a sealing frame is fixedly arranged at the lower end of the fixed frame inside the housing. A second electric push rod is fixedly arranged on the surface of the sealing frame. The movable end of the second electric push rod is fixedly connected to the fixing plate. By the contraction of the second electric push rod, the fixing plate can be driven to move downward. At this time, the corrugated flexible connection bin can move the fixing plate and the filter bag downward, so that the fixing plate and the sealing frame are fitted. In this way, when storing, only the dust will be raised inside the collection bin, and the position in the partition is relatively clean. In this way, the filtration of the soot can be continued quickly, and there is no need to worry about the dust that has just been shaken off adhering to the outer surface of the filter bag again.

[0011] Preferably, a plurality of through holes are evenly formed on the outer surface of the partition. Through the through holes, it is convenient for the flue gas to be filtered to come into contact with each filter bag structure through the partition for filtration.

[0012] Preferably, a ladder is fixedly arranged on the outside of the housing, and a guardrail is fixedly arranged at the upper end of the housing. Through the ladder, it is convenient for the staff to enter the upper end of the housing, and then the safety of the staff can be ensured through the guardrail.

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

[0014] 1. The utility model can perform pulse backblowing on the filter bag as needed through the pulse mechanism. The compressed air in the air bag rushes into the shell through the blowing pipe. The instantaneous impact generated by the high-pressure air causes the dust accumulated on the outer surface of the filter cartridge to fall from the filter cartridge; and finally enters the collection bin for collection; before this, the second electric push rod can be retracted to move the fixed plate downward. At this time, the corrugated soft connection bin can move the fixed plate and the filter bag downward, so that the fixed plate and the sealing frame fit together. In this way, during storage, only dust will be raised inside the collection bin, and the position in the partition is relatively clean, so that the smoke and dust can be quickly filtered, and there is no need to worry that the dust just shaken off will re-attach to the outer surface of the filter bag.
