Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and in particular to a dust removal device. Background Technology

[0002] Water treatment dust removal equipment generally refers to wet scrubbers, commonly known as "demisters". It is a device that brings dust-laden gas into close contact with a liquid (usually water), and uses the inertial collision of water droplets and particles, or the full mixing of water and dust, and other effects to capture particles, enlarge particles, or retain them in a fixed container to achieve the effect of separating water and dust. A water cyclone wet scrubber is a type of wet scrubber.

[0003] Most existing wet scrubbing dust collectors do not have a slag removal device. After the dust is captured by the liquid, the dust collector often needs to be shut down and the slag removal tank needs to be calmed before the operator can manually remove the impurities. Otherwise, the excessive impurities mixed in the liquid may affect the capture effect of the liquid on the dust particles, which has certain limitations. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0045] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0046] Given that most existing wet cyclone dust collectors do not have a slag removal device, after the dust is captured by the liquid, the dust collector often needs to be shut down and the slag removal tank needs to be calmed before the operator can manually remove the impurities. Otherwise, the excessive impurities mixed in the liquid may affect the collection effect of the liquid on the dust particles, which has certain limitations.

[0047] like Figure 1-7As shown, this utility model embodiment provides a dust removal device, including: a first housing 1 with an air inlet 2 on one side; a water vortex chamber 3 disposed inside the first housing 1; a fan 4 installed inside the first housing 1; a pool 5 disposed on one side of the first housing 1, with a through groove 8 between the pool 5 and the first housing 1; a sludge removal assembly 6 disposed inside the pool 5 for filtering impurities in the liquid in the pool 5, the sludge removal assembly 6 including: a second housing 61 placed inside the pool 5, with a groove 613 inside the second housing 61; a float 62 fixedly connected to the top of the second housing 61; and a baffle 63 for rotating... A baffle 63 is movably connected to the top of the second tank 61. The top of the baffle 63 rises and falls with the liquid level inside the pool 5 and blocks large impurities floating on the liquid surface above the second tank 61. A frame 64 is placed inside the groove 613, and the bottom of the second tank 61 is located above the top of the frame 64 to facilitate the entry of liquid into the frame 64. A first filter screen 65 is installed at the bottom of the frame 64. A through hole 66 is opened inside the second tank 61. A water pump 67 is installed inside the second tank 61. The water inlet of the water pump 67 is connected to the through hole 66, and the water outlet of the water pump 67 is fixedly connected to a pipe extending to the outside of the second tank 61.

[0048] In use, cleaning water is added to the interior of chamber 1 using a water pump (the water supply principle is the same as that of a regular water pump, not shown in the diagram, and will not be described in detail here). The liquid level inside chamber 1 is positioned between the bottom of the water vortex chamber 3 and the bottom of the air inlet 2 (the liquid level is observed through a glass panel on one side of chamber 1; this glass panel is existing technology and not shown in the diagram, and will not be described in detail here). Then, fan 4 is turned on to draw air from inside chamber 1, creating a negative pressure. Under this negative pressure, the air inlet 2 draws the dust to be cleaned into chamber 1, and the cleaning water is also drawn in by the pressure. The dust enters the water vortex chamber 3 and forms a water vortex there. The water vortex intercepts the dust. Dust particles with a density less than water will flow into the interior of the pool 5 through the channel 8 with the water flow and float on the surface of the liquid in the pool 5. The operator only needs to use a scooping tool to scoop out the impurities floating on the surface of the liquid in the pool 5. When the liquid level inside the No. 1 box 1 is lower than that in the water vortex chamber 3, the water pump will replenish the cleaning water to the level between the bottom of the water vortex chamber 3 and the bottom of the air inlet 2. The dust sucked in by the air inlet 2 can be cleaned by circulating the cleaning water. (The main body of this device is similar to a water vortex wet dust collector. The dust removal principle is existing technology and will not be described in detail here.)

[0049] After introducing cleaning water into the interior of tank 1 and starting the blower 4, tank 61 is placed into the interior of pool 5. Then, the water pump 67 is started. Because tank 61 has a float 62 at its top, and the float 62 has a low density, typically 400 kg / m³, this process is necessary. 3According to the buoyancy formula, the buoyancy generated on the second tank 61 is: water density × gravitational acceleration × volume of water discharged from the second tank 61. The overall weight of the slag removal assembly 6 is: mass of the slag removal assembly 6 × gravitational acceleration. Since the density of the float 62 is relatively small, when the product of the volume of water discharged by the float 62 and the liquid density equals the mass of the entire slag removal assembly 6, the slag removal assembly 6 can float on the liquid surface in the pool 5. The liquid surface in the pool 5 is located between the top of the second tank 61 and the top of the float 62. The top of the second tank 61 is higher than the top of the frame 64, which facilitates the pump 67 to draw the liquid in the pool 5 from above the frame 64 into the interior of the frame 64. The liquid is then filtered through the first filter screen 65, trapping impurities larger than the pores of the first filter screen 65 at its top. The filtered liquid is then transported through the through hole 66. The liquid enters the water pump 67 and is then output to the tank 5 through the water pipe connected to the water pump 67 and the outlet. This continuously removes sludge from the liquid inside the tank 5. Simultaneously, as the water pump 67 continuously draws liquid from the tank 5 and discharges the filtered liquid into the tank 5, the liquid level inside the tank 5 fluctuates. The top of the baffle 63 moves up and down with the fluctuation of the liquid level, and the top of the baffle 63 is often below the liquid level during fluctuations. This facilitates the liquid entering the second tank 61 from above the baffle 63. At the same time, the baffle 63 also stands upright at an inclined angle under the action of buoyancy, thereby blocking the impurities drawn into the second tank 61 and preventing the impurities drawn into the second tank 61 from being moved out of the second tank 61 with the fluctuation of the liquid level, further enhancing the filtration effect of impurities.

[0050] Furthermore, the frame 64 is installed on the top of the second box 61 via the limiting component 7; the limiting component 7 includes: a frame 71, which is fixedly connected to the top of the frame 64; a threaded hole 72, which is opened at the same position on the top of the frame 71 and the second box 61; and a threaded rod 73, which is threaded into the inside of the threaded hole 72, and the frame 71 is fastened to the top of the second box 61 via the threaded rod 73.

[0051] When installing the frame 64, first position the frame 71 facing the side with the threaded hole 72 on the top of the second box 61, and insert the frame 64 into the interior of the second box 61. At this time, the bottom of the first filter screen 65 is in contact with the top of the groove 613. Then, the operator takes out the threaded rod 73 and screws it into the threaded hole 72. The threaded action of the threaded rod 73 secures the frame 71 to the second box 61. When it is necessary to disassemble the frame 64, simply turn the threaded rod 73 in the opposite direction to unscrew it from the threaded hole 72. Then, the operator holds the handle (not shown in the figure) and pulls the frame 71 and the frame 64 upward together to remove the frame 64 from the interior of the second box 61 for easy cleaning.

[0052] Furthermore, a rubber head 731 is provided on the top of the threaded rod 73, which makes it easy for the operator to turn the threaded rod 73 by hand.

[0053] Furthermore, when the frame 71 is securely connected to the top of the second box 61, the bottom of the first filter 65 contacts the top of the groove 613, and the top of the groove 613 supports the first filter 65, thereby enhancing the stability of the first filter 65.

[0054] Furthermore, sliders 611 are fixedly connected to both sides of the second box 61, and a sliding groove 612 is opened inside the pool body 5 to slide in connection with the sliders 611. The sliding groove 612 guides the sliders 611, making it easier to guide the second box 61 to slide up and down, preventing the second box 61 from drifting inside the pool body 5 with the fluctuation of the liquid surface, which would make it inconvenient for the operator to operate the second box 61.

[0055] Furthermore, a screw 631 is threadedly connected to one side of the second housing 61 to block the baffle 63 and prevent the baffle 63 from rotating to the side away from the second housing 61, thus affecting the baffle 63's blocking effect on impurities.

[0056] Furthermore, the bottom of the first filter screen 65 has a mounting hole 651. The first filter screen 65 is connected to the bottom of the frame 64 by a second screw 652 that passes through the mounting hole 651. When the second screw 652 is tightened, its end is located inside the first filter screen 65, and a sealing gasket 653 is provided between the mating surfaces of the first filter screen 65 and the frame 64 to enhance the sealing of the mating surfaces of the first filter screen 65 and the frame 64. Since the end of the second screw 652 is submerged in the mounting hole 651 when tightened, the end of the second screw 652 will not protrude from the mounting hole 651, causing the bottom of the first filter screen 65 to be uneven. This would result in the first filter screen 65 not fitting snugly against the groove 613, affecting the filtration effect.

[0057] Furthermore, a second filter screen 661 is installed on the top of the through hole 66. When the frame 64 and the first filter screen 65 are removed from the top of the second housing 61 for cleaning, the second filter screen 661 can also filter the liquid entering the water pump 67 to prevent impurities from entering the water pump 67 and affecting its lifespan.

[0058] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
