Technical Field

The utility model relates to a dust removal field specifically discloses a sack cleaner.

Background

Chromium has excellent properties of hardness, brittleness, corrosion resistance and the like, so that chromium is widely applied to the fields of metallurgy, chemical engineering, cast iron, fire resistance, high-precision science and technology and the like. Hexavalent chromium is an ingestible poison/inhalation toxicant, however, skin contact may lead to sensitization; more likely to cause genetic defects, possibly carcinogenic by inhalation, and persistent environmental hazards, and thus waste chromium needs to be recovered. The waste containing hexavalent chromium comprises waste water and waste residues, and the waste residues need to be subjected to multi-stage treatment such as drying, crushing, rotary kiln and the like when being recycled, dust is generated in the treatment process, and the dust needs to be removed for the health of workers.

At present, a bag-type dust collector is generally adopted to remove dust, and the bag-type dust collector is a dry dust filtering device and is suitable for collecting fine, dry and non-fibrous dust. The patent of application number 201711476631.0 discloses a sack cleaner, including the box, the baffle, the sack, bag cage isotructure sack, the bottom half is equipped with the dust export and installs the rotary valve, the sack adopts weaving filter cloth or non-woven felt to make, utilize fabric's filter action to filter dirty gas, after dirty gas gets into bag collector, the granule is big, the dust that the proportion is big, because the effect of gravity subsides, fall into the bottom half, the gas that contains more tiny dust is when passing through the filter material, the dust is detained, make gas obtain purifying.

But the sack life-span is limited, need change after using a period, and to avoid the different damage time that leads to of life difference to be different moreover, so need change all sacks simultaneously, and the sack generally installs alone in the sack cleaner, and every sack needs to be dismantled alone and install during the change, changes inefficiency.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a quick dismantlement is sack cleaner of all sacks down.

In order to achieve the above purpose, the technical scheme of the utility model is that: a bag-type dust collector comprises a box body, a cover body, a partition plate and a plurality of filtering mechanisms, wherein the partition plate is transversely fixed in the box body, a plurality of mounting holes which are in one-to-one correspondence with the filtering mechanisms are formed in the partition plate, an air outlet and an air inlet are formed in the box body, and the air outlet and the air inlet are respectively positioned on the upper side and the lower side of the partition plate; the cover body is detachably fixed at the top of the box body; the filtering mechanism comprises a bag cage and a cloth bag positioned in the bag cage, the upper end of the bag cage is detachably connected with the partition plate, a limiting block is fixed at the upper end of the cloth bag, and one end of the limiting block, which is far away from the cloth bag, is attached to the partition plate; a plurality of lower ends of the lower pressing rods are fixed on the cover body and are abutted against the limiting blocks.

Because the length of the vertical section of the L-shaped rod 21 is greater than the sum of the lengths of the fixing hole and the threaded hole, after the L-shaped rod 21 is completely screwed in, the lower end of the L-shaped rod 21 is attached to the sliding block 14 and pushes the sliding block 14 downwards, the pressure spring 15 is compressed, the L-shaped rod 21 is subjected to an upward acting force, the pressure between the L-shaped rod 21 and the threads on the threaded hole is increased, the friction force is increased, and the L-shaped rod 21 is prevented from loosening.

Example 2

On the basis of embodiment 1, as shown in fig. 5 and 6, an air inlet pipe 6 is transversely arranged above the partition plate 3 in this embodiment, the left end of the air inlet pipe 6 penetrates through the left wall of the box body 1, an annular fixing ring 64 is welded at the left end of the air inlet pipe 6, and the fixing ring 64 is fixed with the left wall of the box body 1 through bolts, so that the air inlet pipe 6 is fixed. A spring 63 is arranged at the left end of the air inlet pipe 6 and is sealed with the piston 62 in a sliding manner, and two ends of the spring 63 are respectively welded on the piston 62 and the inner wall of the air inlet pipe 6; the top wall of the intake pipe 6 is provided with a vent groove 61, the vent groove 61 is positioned at the right side of the piston 62, and when the piston 62 slides to the right as shown in fig. 7, the space at the left side of the piston 62 is communicated with the space at the right side of the piston 62 through the vent groove 61.

As shown in fig. 5 and 6, the lower end of the air inlet pipe 6 is vertically provided with high-pressure air pipes 7 with the same number as the mounting holes, the high-pressure air pipes 7 correspond to the mounting holes one by one, all the high-pressure air pipes 7 are positioned at the right side of the piston 62, and the lower ends of the high-pressure air pipes 7 are positioned in the cloth bag 5; the upper end of the high-pressure air pipe 7 upwards penetrates through the bottom of the air inlet pipe 6 and is located in the air inlet pipe 6, a gear is welded at the upper end of the high-pressure air pipe 7, a rack meshed with the rack is transversely welded on the right wall of the piston 62, the distance between the left end of the vent groove 61 and the left end of the leftmost gear is larger than the thickness of the piston 62, and therefore when the right wall of the piston 62 abuts against the leftmost gear, the left end of the vent groove 61 is located on the left side of the piston 62.

All the left sides of intake pipe 6 are vertical to be equipped with arc 72, and the arc 72 right wall pastes with intake pipe 6 outer wall, and arc 72 upper end welding is on intake pipe 6, and the lower extreme is as high as intake pipe 6 lower extreme.
