Description

Technical Field

[0002] Sintering refers to the conversion of powdered materials into dense bodies. It is a traditional process used to produce ceramics, powder metallurgy, refractory materials, ultra-high temperature materials, etc. During the sintering process, flue gas is generated, which contains dust.

The filter array refers to multiple filter bags 303 arranged in multiple rows. The multiple filter bags 303 arranged in sequence along the front and back of each support plate 301 form a row.

[0036] A support assembly 4 is provided on the outside of the protective outer cover 1, and the middle part of the support assembly 4 is located above the protective outer cover 1. The support assembly 4 includes a first support platform 401 and a second support platform 402. The first support platform 401 is provided at the rear of the protective outer cover 1, and the second support platform 402 is provided in the front of the protective outer cover 1. Two sliding rods 403 extending forward and backward are fixedly connected between the front side surface of the first support platform 401 and the rear side surface of the second support platform 402. The sliding rod 403 is located above the protective outer cover 1. A cover plate 5 is slidingly provided between the two sliding rods 403. The left and right ends of the cover plate 5 are provided with sliding openings that are transparent front and back. The left and right ends of the cover plate 5 are movably sleeved on the sliding rod 403 on the same side through the sliding opening. The upper surface of the filter assembly 3 is in contact with the lower surface of the cover plate 5, and the cover plate 5 presses the filter assembly 3 into the mounting groove 2.

[0037] The cover plate 5 is provided with a plurality of air inlet avoidance ports which are transparent up and down. The air inlet avoidance ports correspond to the corresponding blowing ports 302 up and down. An air inlet hopper 501 is vertically provided inside the air inlet avoidance port.

[0038] The pulse jet 6 is installed on the first support platform 401. The pulse jet 6 includes a gas tank and a pulse valve. The gas tank is fixedly installed on the first support platform 401.

[0039] An observation window 7 is provided on the front side of the protective cover 1. The observation window 7 corresponds to the front and rear positions of the filter array. A blower 12 is provided on the inner wall of the protective cover 1. In this embodiment, a conventional knuckle nozzle can be used as the blower 12. The blower 12 is located above the observation window 7 and is connected to the gas tank. When the blower 12 blows air to the filter bag 303, it also blows air to the inner wall of the observation window 7 to prevent the dust from being shaken off from adhering to the inner wall of the observation window 7.

[0040] A recovery device is provided in the protective outer cover 1, and the recovery device is an upper opening structure. The recovery device is located in the filter cavity and is located below the filter array. A discharge avoidance port is provided at the lower part of the front side of the protective outer cover 1. The feed box 10 is slidably arranged inside the filter cavity. The feed box 10 is an upper opening structure and is located below the filter array. The front side of the feed box 10 passes through the discharge avoidance port, and a handle 11 is fixedly connected to the front side of the feed box 10.

[0041] An air inlet 8 is provided on the protective outer cover 1 and is communicated with the filter chamber. An air outlet 9 is provided on the right side of the protective outer cover 1 and is communicated with the interior of the filter chamber. A ventilation grille is fixedly connected to the air outlet 9.

[0042] Working principle: The staff connects the air inlet 8 to the sintering device. During the sintering process, the sintering device is exhausted. The exhausted flue gas enters the filter chamber through the air inlet 8. The gas in the flue gas passes through the filter array, and the dust adheres to the outer surface of the filter bag 303. The filtered gas is discharged through the air outlet 9.

[0043] The staff observes the dust adhesion on the filter bag 303 through the observation window 7. When the degree of adhesion is high, the staff supplies gas to the pulse valve through the gas tank, and the pulse valve supplies gas to the blowpipe. The blowpipe blows the gas into the air inlet hopper 501 below through the pulse nozzle, and enters the air inlet avoidance port through the air inlet hopper 501. Below the air inlet avoidance port is the blowpipe 302. The gas enters the corresponding filter bag 303 through the blowpipe 302. The filter bag 303 vibrates after the gas enters, and the dust attached to the filter bag 303 is shaken off to the feed box 10.

[0044] After long-term use, when the filter bag 303 is worn or needs to be removed for deep cleaning, the staff pulls the cover plate 5, and the cover plate 5 moves forward, so that the support plate 301 is out of contact with the lower surface of the cover plate 5. The staff pulls the support plate 301 out of the installation slot 2, thereby pulling out the filter bag 303, replaces or cleans the filter bag 303, and then puts the support plate 301 back into the installation slot 2, and then resets the cover plate 5, and the cover plate 5 presses the support plate 301 into the installation slot 2 again.

[0045] In this way, the filter bag 303 can be quickly replaced and disassembled. At the same time, the filtration is carried out through the filter array, and the filtration effect is better. In addition, during the cleaning process of the filter bag 303, the observation window 7 can be assisted in blowing dust to prevent dust from adhering to the observation window 7.

[0046] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is determined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
