Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a dust collector. Background Art

[0002] The equipment that separates dust from flue gas is called a dust collector or dust removal equipment.

[0003] A pulse valve is a diaphragm valve that is controlled by a pilot valve such as electromagnetic or pneumatic, and can open and close a high-pressure gas source instantaneously to generate a pulse. It is a valve that changes the input long signal into a pulse signal by the delay action of air flow through air resistance and air capacitance. The pulse valve is a main component of the dust collector, and the number of blowings reaches more than 1 million times.

[0004] The utility model patent with the publication number of CN 213433548 U and the publication date of June 15, 2021 discloses a dust collector, which includes a housing, and a dust discharge port is provided at the bottom of the housing; at least two mounting brackets are symmetrically arranged on both sides of the dust discharge port of the housing respectively; the upper end of the dust storage trolley has an opening, and the opening is not less than the size of the dust discharge port. Support lugs are provided at the opening of the dust storage trolley; two support members are respectively hinged to the mounting brackets, and the support members have a first position and a second position around the mounting brackets. In the first position, the support members abut against the lower surface of the support lugs to lift the dust storage trolley, so that the edge of the opening of the dust storage trolley abuts against the edge of the dust discharge port of the housing; in the second position, the support members of the dust storage trolley are separated from the support lugs; it greatly facilitates the storage and transfer of dust in the dust collector; it also reduces the large amount of dust falling at the sealed housing when the dust storage trolley is transferred, resulting in ineffective dust storage;

[0005] Although this patent reduces the original sealed housing and avoids a large amount of dust falling at the sealed housing, another problem is also exposed during the implementation of this patent: that is, when the height of the dust accumulation in the dust storage trolley exceeds the height of the carriage of the dust storage trolley, it will overflow outward into the dust discharge port. In this case, when the dust storage trolley is pulled outwards, the part of the dust in the dust discharge port will fall to the ground again after the dust storage trolley is pulled out. That is to say, the dust discharge port acts as a scraper at this time, resulting in incomplete dust cleaning and secondary dust cleaning problems.

[0006] Therefore, there is an urgent need for a dust collector to improve the quality of dust cleaning and avoid the occurrence of secondary dust cleaning. Utility Model Content

[0007] In view of the above technical problems, the utility model provides a dust collector to solve the problem of incomplete dust cleaning and secondary dust cleaning in the existing dust collector.

[0035] Refer to the attached Figures 1-8 , as shown is a dust collector, including a housing 1. A plurality of feet 2 are provided at the bottom of the housing 1. The feet 2 are used to separate the entire housing 1 from the ground, reducing the contact area with the ground to prevent rust. Inside the housing 1, a first mounting plate 5 and a second mounting plate 6 are provided from top to bottom. The first mounting plate 5 is fixed to the inner wall of the housing 1. A fan 7 is mounted on the first mounting plate 5. The fan 7 is equipped with an air outlet pipe 4 and an air connection pipe 8. At the same time, a plurality of air connection ports 9 are provided on the air connection pipe 8. A control box 32 for controlling the start and stop of the fan 7 is also provided on the first mounting plate 5. The control box 32 is electrically connected to an external power supply. At the same time, an air bag 10 is bolted to the inner wall of the housing 1. The air bag 10 is equipped with a pulse solenoid valve. The air bag 10 is provided with an air inlet 11 and a plurality of air outlets 12. The air inlet 11 is connected to an external air compressor to provide a gas source;

[0036] On one side of the second mounting plate 6, a dust removal chamber 13 is connected. Inside the dust removal chamber 13, multiple filter cartridges 15 are installed. One end of each filter cartridge 15 is provided with a cartridge cover 16. The filter cartridges 15 are fixed to the second mounting plate 6 through the cartridge covers 16. At the same time, an air inlet pipe 3 is provided on the side wall of the dust removal chamber 13. Each cartridge cover 16 is provided with a pneumatic valve 17. The pneumatic valve 17 is provided with an air inlet end, a backwash end 19 and an air outlet end 18. Among them, the air outlet end 18 is connected to the air connection port 9 through a flexible rubber tube. The air inlet end is communicated with the filter cartridge 15, and the backwash end 19 is connected to the air outlet 12 on the air bag 10. During use, the fan 7 sucks the waste gas into the dust removal chamber 13 through the air inlet pipe 3. Then, the waste gas filters the dust under the filtering action of the filter cartridges 15. The filtered gas enters the fan 7 through the flexible rubber tube and then is discharged from the air outlet pipe 4. When it is necessary to remove dust from the filter cartridges 15 themselves, the high-pressure gas is reversely sprayed onto the filter cartridges 15 in a pulsed manner through the cooperation of the air bag 10 and the pulse solenoid valve to achieve dust removal;

[0037] Further, a plurality of guiding and limiting members 25 are circumferentially provided at the port of the dust removal chamber 13. The guiding and limiting members 25 are provided with a flat plate portion 26. One end of the flat plate portion 26 is provided with an inclined portion 27. The inclined portion 27 inclines outward relative to the flat plate portion 26. A dust bucket 14 is arranged at the port of the dust removal chamber 13. One end of the dust bucket 14 close to the dust removal chamber 13 is provided with a lapping flange 28. In order to improve the sealing performance between the dust removal chamber 13 and the dust bucket 14, a sealing ring 29 is provided on one side of the lapping flange 28. The dust removal chamber 13 is lapped on the dust bucket 14 through the guiding and limiting members 25;

[0038] At the same time, a lifting mechanism is provided on the second mounting plate 6. The lifting mechanism includes sliding frames 20 arranged on both sides of the second mounting plate 6. One end of each sliding frame 20 is provided with a guiding plate 21. The guiding plate 21 is provided with a ramp-shaped guiding portion 22. At the same time, guiding wheels 23 are cooperatively arranged on the guiding portion 22. The guiding wheels 23 are rotatably arranged on the support 24 through a wheel shaft. The support 24 is fixed to the side wall of the housing 1. At the same time, a hatch 35 is provided at the position of the housing 1 corresponding to the dust removal chamber 13. When cleaning the ash, the hatch 35 is opened, and then the second mounting plate 6 is pulled outwards. The second mounting plate 6 slides along the guiding wheels 23 through the guiding portion 22. At this time, the entire second mounting plate 6 is lifted upwards under the supporting action of the guiding wheels 23, so that the dust removal chamber 13 is separated from the dust bucket 14, and all the dust falls into the dust bucket 14. Then, the dust can be completely removed from the lower part of the dust removal chamber 13 through the dust bucket 14. Therefore, it is avoided that the dust higher than the dust bucket 14 falls to the ground under the rubbing of the dust removal chamber 13, causing the problem of secondary ash cleaning;

[0039] At the same time, in order to facilitate pulling the second mounting plate 6, a handle 30 is provided on the second mounting to facilitate the application of force. In addition, a handle 31 is also configured on the dust bucket 14 for pulling the dust bucket 14 outwards;

[0040] Meanwhile, in order to improve the matching accuracy between the ash bucket 14 and the dust removal chamber 13 and avoid dust overflow caused by butt joint misalignment, a limiting plate 33 is provided at the position of the ash bucket 14 on the housing 1. A limiting arc opening 34 is formed on the limiting plate 33. After the ash bucket 14 is placed in the limiting arc opening 34, the dust removal chamber 13 and the ash bucket 14 are exactly in a concentric relationship.

[0041] During dust removal, the fan 7 is started through the control box 32. The fan 7 sucks the waste gas into the dust removal chamber 13 through the air inlet pipe 3 on the dust removal chamber 13. Then, the waste gas is filtered under the action of multiple filter cartridges 15, and the dust is accumulated in the ash bucket 14 below. Then, the filtered gas enters the fan 7 through the flexible rubber tube by the pneumatic valve 17, and then is discharged from the air outlet pipe 4. When cleaning the ash bucket 14, the pneumatic valve 17 is closed. At this time, the air inlet pipe 3 and the flexible rubber tube are in a blocked state. Then, the high-pressure air in the air bag 10 is sprayed onto the filter cartridges 15 through the pipeline from the backflush end 19 by the pulse solenoid valve to remove the dust on the filter cartridges 15. Then, the hatch door 35 is opened and the second mounting plate 6 is pulled outwards through the handle 30. The second mounting plate 6 is lifted under the cooperation of the guide wheels 23 and the guiding portion 22, and the dust removal chamber 13 and the ash bucket 14 are separated. Then, the ash bucket 14 can be pulled out of the housing 1 by using the handle 31.

[0042] The above is only the preferred specific implementation manner of the present invention, and does not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
