Background
A large amount of dust is generated in the processing of cutting and polishing stone materials. Most of stone processing is equipped with a dust removing device to reduce environmental pollution and ensure production environment. As shown in fig. 3, the conventional stone dust removing mechanism is mostly implemented by filtering with two filtering layers consisting of a hard plastic filtering layer 100 and a paper filtering layer 200. After the dust air enters the air inlet of the dust removal device, the configured spraying mechanism 300 sprays water towards the hard plastic filter layer 100, most dust in the air is intercepted on the hard plastic filter layer 100, and the intercepted dust is flushed and reflowed to the water tank at the bottom through water flow.
As shown in fig. 3, during the operation of the dust removing device, the dust air travels along an L-shaped linear stroke (the direction of the dust air is shown by the arrow in fig. 3). When the hard plastic filter layer 100 and the paper filter layer 200 have good permeability, the dust air passes through the two filter layers too fast, so that the dust brushing rate of the spraying mechanism 300 is low; and when two filtering layers are gradually blocked due to the deposition of dust, the workload of the exhaust port is increased, the dust removal rate of the dust is also sharply reduced, the dust removal effect is poor, the two filtering layers are frequently replaced, so that the use cost is high, the use is also troublesome, and the practicability of the product is poor.

Similarly, the air in the second negative pressure region 11b is exhausted to reduce the air pressure in the second negative pressure region 11b, so as to further promote the dust removal valve 22 of the water filtering and dust removing mechanism 2 in the lower layer to rise, the air in the region 11c to be filtered is sucked into the second negative pressure region 11b, and the air outside the air inlet is sucked into the region 11c to be filtered, so that the air to be filtered flows according to the set path of the air inlet 10, the dust removal chamber 11 and the air outlet of the main cabinet 1. The power of the exhaust fan 14 required by the dust removal cabinet is preferably 1.3-1.8 times of that of a commercial dust removal device with the same structure and size. And a one-way valve structure can be arranged at the air outlet, so that the negative pressure in the dust removing chamber 11 is quickly and stably formed, and the running stability of the dust removing cabinet can be further improved.
The closed partition 21 is formed by splicing a fixed plate 211 and a movable shutter 212 in a closed manner. The movable shutter 212 is rotatably mounted on the fixed plate 211 or the inner sidewall of the clean room 11 through a hinge as a fixed axis, the movable shutter 212 is opened by swinging downward or closed by swinging upward through a motor or a manual drive, and a sealing member is disposed on the peripheral edge of the movable shutter 212. When the main cabinet 1 is driven by human power, the main cabinet 1 is provided with a limiting mechanism for keeping the closed state of the closing partition 21, the limiting mechanism can be, for example, a sliding block which can move directionally along a horizontal guide rail, when the sliding block is removed, the movable gate plate 212 can rotate freely, and when the sliding block is reset, one end of the movable gate plate 212, which is far away from the rotating shaft, can be propped against so as not to rotate. And the motor-driven movable gate plate 212 may not be configured with the limiting mechanism. When the accumulated dust of the closed partition plate 21 is cleaned, the movable flashboard 212 can be opened, so that the cleaned accumulated dust can be discharged through the opened opening, and the cleaning convenience is improved.
The closed partition plate 21 and the horizontal plane form an included angle of 5-30 degrees. The movable gate 212 is disposed at a low position. The closed partition 21 is a rectangular partition, and the closed partition 21 extends obliquely from bottom to top along the width direction thereof. The water tank 12 is provided with a water pump 122 for supplying water to the water filter 23 at regular time and quantity, and the water loss during the dust removal of the water filter 23 is compensated. The fixed strainer 121 that is equipped with of basin 12, the confined strainer is enclosed into with basin 12 lateral wall to strainer 121, and the water that contains the dust in basin 12 filters this strainer through strainer 121, and above-mentioned water pump 122 assembles in this strainer, as shown in fig. 1, the strainer can set up the position setting that deviates from above-mentioned activity flashboard 212 to the waste water that falls when reducing clearance water filter 23 gets into the probability of this strainer. The water pump 122 is provided with a spray mechanism 112, the spray mechanism 112 includes a main pipe 113 and a plurality of nozzles 114 arranged linearly, the water pump 122 delivers the water in the filtered water to the main pipe 113 and sprays the water through the nozzles 114, and the spray mechanism 112 is used for spraying the dust on the upper surface of the closed partition 21.
