Technical Field

[0001] This application relates to the technical field of wet dust collectors, and more specifically, to a direct-current type wet high-efficiency dust collector. Background Art

[0002] A wet dust collector can capture and remove dust particles in the air. Through its special air flow design and washing mechanism, the dust-containing air is inhaled and brought into full contact with the washing liquid, so that the dust is adsorbed, aggregated and settled, thereby reducing the dust concentration in the air and improving the working environment.

[0003] However, in the prior art, the wet dust collector generally undergoes primary dust removal. For example, as disclosed in the application number: 201120160922.0, and the patent name is Dust Removal Washing Machine: "It includes a housing with an air inlet at the front end and an air outlet at the rear end. There is a water inlet pipe for spraying washing liquid into the housing at the air inlet. A closed motor cylinder is fixed inside the housing, and the motor is installed inside the motor cylinder. The motor is connected to a centrifugal impeller for inhaling dirty air and washing liquid and combining the two. The centrifugal impeller is located inside the air inlet. The inside of the housing serves as a dehydration space, and there is a water receiving tank at the lower part inside the housing." The above prior art only performs primary dust removal. Therefore, in actual use, especially when the dust concentration is relatively high, the dust removal effect on the dust is not good. Utility Model Content

Specific embodiments

[0023] Next, the technical solutions in some embodiments of the present application will be described in conjunction with the accompanying drawings in some embodiments of the present application.

[0024] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0025] As Figure 1 and 2 shown, the embodiment of the present application provides a direct-current type wet high-efficiency dust collector, including a first cylinder 1 and a second cylinder 2 connected to each other. One side of the first cylinder 1 is an air inlet. A fan is arranged inside the first cylinder 1. After the fan is started, negative pressure can be generated to suck the soot into the first cylinder 1. At least one vibration string filter plate 4 is arranged inside the second cylinder 2. The vibration string filter plate 4 can play the roles of dust collection and filtration. Water is sprayed through the first water spraying mechanism 5 at the position of the air inlet. After the fan is started, a swirling airflow is formed, and there is a large amount of water mist, so that the soot is mixed with the water mist, playing the role of primary dust removal; and the soot that is not mixed with the water mist continues to enter the second cylinder 2. Since the second water spraying mechanism 6 is also arranged on the side of the vibration string filter plate 4 facing the air inlet, the second water spraying mechanism 6 continues to spray water mist, so that the mixture of the soot and the water mist directly falls onto the vibration string filter plate 4, and the vibration string filter plate 4 further realizes the roles of dust collection and filtration, thereby improving the dust removal effect of the wet high-efficiency dust collector.

[0026] Optionally, the first cylinder 1 and the second cylinder 2 can be fixed by a plurality of bolts.

[0027] As Figure 5 shown, optionally, the vibrating wire filter plate 4 is generally composed of a bracket, warp stainless steel wires and weft stainless steel wires. The warp stainless steel wires are vertically arranged at intervals on both side surfaces of the bracket, and the weft stainless steel wires are horizontally arranged at intervals in the middle of the bracket. The two warp stainless steel wires and the weft stainless steel wires are separated from each other to form two sets of filter meshes.

[0028] Optionally, the vibrating wire filter plate 4 can be detachably connected to the second cylinder 2 by bolts or other clamping forms. On the one hand, the vibrating wire filter plate 4 can be detached regularly for cleaning. In addition, the vibrating wire filter plate 4 can be replaced regularly.

[0029] Optionally, the first water spraying mechanism 5 includes a water pipe and a nozzle. Among them, the nozzle is arranged towards the direction of the fan, and the water pipe extends to the central position of the air inlet. Water mist is sprayed out through the nozzle in all directions to improve the dust removal effect.

[0030] Optionally, a water pump or the like can be connected to the outside of the water pipe, and the first water spraying mechanism 5 has the same structure as the second water spraying mechanism 6.

[0031] As Figure 2 and 3 shown, as an implementation manner, the first cylinder 1 includes a body section 11 and a first tapered section 12 connected to each other. The size of the first tapered section 12 is smaller than that of the body section 11, so that the dust not mixed with the water mist can gradually gather in the first tapered section 12 and is convenient to flow into the second cylinder 2 centrally. Of course, the first tapered section 12 is a curved surface structure. Therefore, the first tapered section 12 is also convenient to guide the mixture of the dust and the water mist into the first drainage groove 13; the second cylinder 2 includes a connection section 24, and the connection section 24 is connected to the first tapered section 12. The vibrating wire filter plate 4 is installed on the connection section 24. By providing the connection section 24, an installation space is provided for the vibrating wire filter plate 4 to meet the structural stability of the vibrating wire filter plate 4.

[0032] Optionally, the body section 11 and the first tapered section 12 can be connected by welding. Of course, they can also be connected by bolts.

[0033] Optionally, the connection section 24 and the first tapered section 12 can be connected by bolts.

[0034] As Figure 4 shown, optionally, the connection section 24 is a square structure, so as to be convenient for connecting with the vibrating wire filter plate 4. The connection section 24 can be provided with two positioning grooves in two opposite directions, such as the up and down directions. The vibrating wire filter plate 4 can be inserted into the positioning grooves to play a positioning role.

[0035] As Figure 2 and 3 shown, as an implementation manner, the second cylinder body 2 further includes a gradually expanding section 21 and a second gradually shrinking section 22. By providing the gradually expanding section 21, the air flow can be decelerated. After the air flow velocity is reduced, the air flow will not be able to drive the mixture of soot and water mist. Therefore, the mixture of soot and water mist will fall into the second drain tank 23, improving the dust removal effect. At the same time, the gradually expanding section 21 is a curved surface structure, which can also guide the mixture of soot and water mist on the vibrating wire filter plate 4 into the second drain tank 23. The gradually expanding section 21 and the second gradually shrinking section 22 are connected by a transition section 25. A baffle demister 9 is also installed at the position of the transition section 25. By providing the transition section 25, an installation space is provided for the baffle demister 9. In addition, by providing the baffle demister 9, the function of dehydrating can be achieved, intercepting the water mist, so that the water converges and flows into the second drain tank 23, preventing the air flow flowing out of the second cylinder body from containing a large amount of water mist. Of course, a small amount of the mixture of soot and water mist hits the surface of the baffle demister 9, and the baffle demister 9 can also play a role in dust collection.

[0036] Optionally, the second gradually shrinking section 22 is a curved surface structure. Therefore, it can guide the mixture of soot and water mist and make it flow into the second drain tank 23.

[0037] Optionally, the baffle demister 9 can be detachably connected to the second cylinder body 2 by bolts or other clamping forms. On the one hand, the baffle demister 9 can be regularly disassembled and cleaned. In addition, the baffle demister 9 can be regularly replaced.

[0038] As Figure 4 shown, optionally, the transition section 25 is a square structure, which is convenient for connecting with the baffle demister 9. The transition section 25 can be provided with two positioning grooves in two opposite directions, such as the upper and lower directions. The baffle demister 9 can be inserted into the positioning grooves to play a positioning role.

[0039] Optionally, the transition section 25 can be respectively connected to the gradually expanding section 21 and the second gradually shrinking section 22 by bolts.

[0040] Optionally, the end of the second cylinder body 2 is an air outlet.

[0041] As Figure 2As shown, as an implementation manner, the bottom of the main body section 11 includes a first drain groove 13, and the first drain groove 13 communicates with the first cylinder 1. By providing the first drain groove 13, the mixture of soot and water mist in the first cylinder 1 can be collected and discharged; the bottom of the transition section 25 includes a second drain groove 23, and the second drain groove 23 communicates with the second cylinder 2. Both the second tapered section 22 and the tapered expansion section 21 can play a guiding role to make the mixture of soot and water mist flow into the second drain groove 23. At the same time, a baffle demister 9 is also provided on the transition section 25. The main function of the baffle demister 9 is dehydration. Therefore, after dehydration by the baffle demister 9, the water mist can directly fall into the second drain groove 23 by gravity, which is convenient for discharge.

[0042] Optionally, the first drain groove 13 is inclined to facilitate sewage discharge; the second drain groove 23 is also inclined, which also facilitates sewage discharge.

[0043] As Figure 2 As shown, as an implementation manner, the fan includes an impeller facing the air inlet and a motor 3 connected to the impeller. When the impeller rotates, it can generate a swirling air flow, so that after the soot and water mist are mixed, they move along the outer surface of the waterproof cylinder 7 towards the air guide fan blade 10; the outside of the motor 3 is covered with a waterproof cylinder 7. By providing the waterproof cylinder 7, it can prevent water mist from entering the fan and causing a short circuit to the motor 3.

[0044] Optionally, the motor 3 can be powered by an external wire.

[0045] Optionally, the waterproof cylinder 7 and the motor 3 can be connected by a flange and bolts.

[0046] As Figure 2 As shown, as an implementation manner, an impeller is installed on the output shaft of the motor 3. The impeller includes an impeller rear disc 8 for blocking water. Through the impeller rear disc 8, it can prevent water mist and soot from entering the motor 3 through the output shaft of the motor 3, thereby playing a role in waterproofing and dustproofing.

[0047] Optionally, the impeller rear disc 8 is conical, and the output shaft and the impeller rear disc 8 can be connected by a connecting plate to improve the stability between the impeller rear disc 8 and the output shaft; the impeller also includes blades 31 and a front disc. Both the blades 31 and the front disc are welded to the impeller rear disc 8. When the output shaft rotates, it drives the impeller to rotate synchronously.

[0048] As an implementation manner, a plurality of support members for supporting the waterproof cylinder 7 are also provided on the outer surface of the waterproof cylinder 7, so as to play a role in fixedly supporting the fan.

[0049] Optionally, the support members are arranged at intervals along the circumferential direction of the waterproof cylinder 7.

[0050] Optionally, the support member can be a metal member to ensure the structural strength.

[0051] As Figure 2 shown, as an implementation manner, an inclined air guide fan blade 10 is further provided between the waterproof cylinder 7 and the first cylinder body 1. The air guide fan blade 10 is of a bent structure. The inclination and the bent structure of the air guide fan blade 10 can enable the air flow to form a spiral air flow. Under the action of centrifugal force, the mixture of soot and water mist enters the first drain tank 13 and flows out of the first cylinder body 1, achieving the purpose of primary dust removal.

[0052] Optionally, the air guide fan blade 10 is respectively connected to the waterproof cylinder 7 and the first cylinder body 1 by welding, so that the air guide fan blade 10 can also play a supporting role.
