On the basis of the above technical solution, this embodiment provides a specific implementation manner of a dust removing device:
for the cyclone chamber 3 described above, its internal space is divided into: cyclone dust chamber 31, cyclone dust chamber 32 and cyclone dust chamber 33. The three air chambers can be separated by the partition plate and are sequentially distributed along the vertical direction. The cyclone dust air chamber 31 is positioned in the middle, the cyclone air purifying chamber 32 is positioned above the cyclone dust air chamber 31, and the cyclone dust discharging chamber 33 is positioned below the cyclone dust air chamber 31.

After entering the cyclone 34 from the inlet, the material is spirally rotated, and the solid particles are dispersed all around by the centrifugal force, fall down along the inner surface of the side wall of the cyclone 34, and are discharged from the solid outlet to the cyclone dust discharge chamber 33.

The number of the cyclones 34 may be one, two or more. The present application uses a plurality of cyclones 34 arranged in a matrix, for example, 9 cyclones arranged in 3 rows and 3 columns.
A specific implementation manner is as follows: fig. 3 is a schematic structural view of a cyclone provided in an embodiment of the present application, and fig. 4 is a sectional view of the cyclone provided in the embodiment of the present application. As shown in fig. 3 and 4, the cyclone 34 is provided with an inner cavity 344 at the inside, a gas outlet 341 at the top, a solid outlet 342 at the bottom, and an inlet 343 at the middle. The inlet 343 is provided with guide plates arranged spirally, and under the action of negative pressure, airflow enters the inner space of the cyclone 34 from the gap between the guide plates to rotate spirally. The solid particles are dispersed all around by centrifugal force and fall down the side walls of the cyclone 34. The gas flow first spirals downward after entering the interior cavity and then reverses direction to spiral upward after moving to the lower cone-center narrowing section until exiting the gas outlet 341.
Furthermore, a wear-resistant baffle 21 is arranged in the gravity settling chamber 2, and the wear-resistant baffle 21 is arranged at the position opposite to the material inlet. The side of the wear barrier 21 facing away from the material inlet 11 forms a passage with the side wall of the gravity settling chamber 2 communicating with the cyclone chamber 3. From the view angle of fig. 1, the wear-resistant baffle 21 divides the middle part and the upper part of the gravity settling chamber 2 into a left space and a right space, and after materials enter the right space from the material inlet 11 for gravity settling, the residual materials enter the cyclone dust air chamber 31 from the left space.
Because large-particle solid can be mixed in the initial material, larger impact force is generated on the wear-resistant baffle 21. The wear-resistant baffle 21 is made of wear-resistant materials or the wear-resistant materials are coated on the surface of the wear-resistant baffle to prolong the service life.
The bore of the lower part of the gravity settling chamber 2 is gradually reduced from top to bottom, a discharge valve is arranged at the discharge outlet at the bottom end of the gravity settling chamber 2, the discharge valve is opened, and large-particle solids are discharged from the discharge outlet.
The inner space of the fine filtering chamber 4 is divided into a fine dust filtering air chamber 42 and a fine filtering air purifying chamber 43, which are separated by a partition plate. The fine filtering air purifying chamber 43 is positioned above the fine dust filtering air chamber 42. The fine dust filtration air chamber 42 is provided with an air filter element 44, and an air outlet of the air filter element 44 is communicated with the fine filtration air purification chamber 43.
The fine dust filtering air chamber 42 is communicated with the cyclone air purifying chamber 32, materials enter the fine dust filtering air chamber 42 from the cyclone air purifying chamber 32, and gas passes through a filter layer of the air filter element 44, enters the fine filtering air purifying chamber 43 and enters the wind source machine from the exhaust port 41 at the end part of the fine filtering air purifying chamber 43. The aperture of the lower part of the fine dust filtration air chamber 42 is gradually reduced from top to bottom, the bottom end is provided with a discharge opening, and the discharge opening is provided with a discharge valve. Smaller particles of solids cannot pass through the air filter element 44 and settle to the discharge opening at the bottom of the fine dust filtration plenum 42, opening the discharge valve to discharge the solids.
The number of the air filter elements 44 is plural, and the air filter elements are arranged in an array. A through hole is formed in a partition plate between the fine dust filtration air chamber 42 and the fine filtration air purification chamber 43, the top of the air filter element 44 is fixed to the through hole of the partition plate, the inner space of the air filter element 44 is communicated with the fine filtration air purification chamber 43, and the fine dust filtration air chamber and the fine filtration air purification chamber are finally separated by a filter element filtering layer. The air filter element 44 may also be replaced with a cloth bag, filter cartridge, or sintered plate.
The discharge valves 5 may be driven by a hydraulic motor, an electric motor, or the like, and the discharge valves 5 are driven to open or close. When the discharge valve 5 is completely closed, a closed airflow channel is formed in the gravity settling chamber 2, the cyclone separation chamber 3 and the fine filter chamber 4. The discharge valve can adopt a star-shaped discharger and also can be a gate valve or a flap valve.
In the scheme, the cyclone 34 is adopted to communicate the cyclone air purifying chamber 32, the cyclone dust air chamber 31 and the cyclone dust discharging chamber 33, so that the gas in the material enters the cyclone air purifying chamber 32 from the top of the cyclone 34, and the separated solid material enters the cyclone dust discharging chamber 33 from the bottom. An air filter element 44 is used to separate the fine dust filtration air chamber 42 and the fine filtration air chamber 43, so that the air passes through the air filter element 44 and enters the fine filtration air chamber 43, and the solid particles which cannot pass through the air filter element 44 are discharged from the bottom of the fine dust filtration air chamber 42. Through the high-speed centrifugal separation of the cyclone separation chamber 3, the dust removal pressure of the fine filter chamber 4 is reduced, and the dust removal effect is better.
The exhaust port 41 is mechanically connected to an air source, and the suction action of the air source mechanism forms negative pressure in the dust removing device, so that high-speed airflow is formed in the space. The material is sucked into the gravity settling chamber 2 from the material inlet 11 by the high-speed airflow, the airflow speed is reduced due to the increase of the sectional area of the airflow channel, the speed of the material is reduced after the material collides with the wear-resistant baffle 21, and the material falls to the discharge opening along the wear-resistant baffle 21 and is discharged through the discharge valve.
The residual fine materials and dust after being treated by the gravity settling chamber 2 enter the cyclone dust air chamber 31, and the airflow enters the interior of the cyclone 34 from the inlet of the cyclone 34. Under the action of the guide vanes of the cyclone 34, the airflow spirally moves downwards at high speed along the inner wall of the cyclone 34, fine materials and dust mixed in the airflow have higher density, and the speed is instantly reduced after the airflow is separated to the outer side of the spiral airflow and collides with the inner wall of the cyclone under the action of centrifugal force, so that the airflow is separated. The separated material and dust fall down along the inner wall of the cyclone into the cyclone dust discharge chamber 33 and are discharged through a discharge valve. The airflow spirally moves downwards to the lower part of the cyclone, then reversely spirally moves upwards, and enters the cyclone air purifying chamber 32 through the gas outlet of the cyclone. The residual fine dust continuously enters the fine dust filtering air chamber 42 along with the air flow, the air in the fine filtering chamber passes through the filtering layer of the air filtering element 44 to enter the inside of the filtering element, and moves upwards to enter the fine filtering air purifying chamber 43, and directly enters the wind source machine through the air outlet 41, so that the wind source machine is not damaged, and the environmental protection requirement is met. The dust and material particles are blocked in the fine dust filtering air chamber 42 by the filtering layer of the air filter element 44, and the final separation of the dust and the air is realized.
In addition, due to the high-speed centrifugal action of the cyclone separation chamber 3, moist dust, liquid drops and the like are more easily separated, and the technical scheme provided by the embodiment can also be used for treating moist water-containing materials to realize dry and wet purposes.
The gravity settling chamber 2, the cyclone separation chamber 3 and the fine filtration chamber 4 are of an integrated structure, are separated by partition plates to form a plurality of spaces, are compact in structure and save space.
Furthermore, a filtering structure such as a filtering screen can be additionally arranged between the gravity settling chamber 2 and the cyclone separation chamber 3, so that the dust removal effect is further improved.
