Description

Technical Field

[0001] This utility model relates to the technical field of equipment for separating particulate matter from gas, and more particularly to a separation and purification device for oil fume and dust-laden waste gas. Background Technology

[0002] Chinese patent CN218452286U discloses a technical solution called an oil fume exhaust gas purification device. The solution is equipped with an electrocoagulation component, a spiral corona discharge component and a static adsorption plate in the box. The spiral corona discharge component includes a rotatable central shaft, a number of discharge electrodes spirally arranged on the central shaft, and a blade frame at the outer end of the discharge electrodes. When the spiral corona discharge component is energized, the discharge electrode discharges, causing the surrounding oil fume exhaust gas to ionize and generate charges. This charges the particulate matter in the oil fume exhaust gas and causes it to agglomerate. Then, the eddy current generated by the high-speed rotation of the spiral corona discharge component causes the agglomerated particles to be subjected to centrifugal force and thus thrown onto the inner wall of the chamber. However, such equipment still has obvious defects in actual use: the combination of oil fumes and particulate matter makes the particulate matter sticky, and the rotating spiral corona discharge component is likely to collide with the particulate matter and be adhered to by the particulate matter. After the particulate matter accumulates on the discharge electrode, it will carbonize and form a dirt layer. This dirt layer usually has insulating properties, which will seriously affect the discharge capacity of the discharge component and lead to a poor purification effect. Utility Model Content

[0003] In view of the shortcomings of existing oil fume and exhaust gas purification devices, which are prone to the formation of insulating dirt layers on the discharge components after long-term use, resulting in poor purification effect, the purpose of this utility model is to provide an oil fume and dust-containing exhaust gas separation and purification device with self-cleaning function.

[0004] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method: A fume and dust-laden exhaust gas separation and purification device includes a housing, in which a spiral discharge component is rotatably arranged. A self-cleaning module is provided on the housing. The self-cleaning module includes a spraying mechanism for spraying cleaning liquid onto the surface of the discharge component and the inner wall of the housing, a brushing mechanism for scrubbing the surface of the discharge component, and a drying mechanism. The brushing mechanism includes a brush component that can move to cooperate with the discharge component and reciprocate along the transmission direction of the discharge component, and a drive component for driving the brush component to move.

[0005] Using the above scheme, the discharge component in this scheme has two modes: high-speed rotation and slow rotation. When the discharge component is working, it will switch to high-speed rotation mode, and when it is self-cleaning, it will switch to slow rotation mode. In slow rotation mode, the rotation speed of the discharge component is between 20 and 30 r / min. During self-cleaning, the discharge function of the discharge component cuts off the power supply. Then, the spray component sprays the cleaning liquid onto the discharge component and the inner wall of the box, softening or dissolving the solidified dirt and making it fluid, thus creating the preconditions for the subsequent brushing steps. The brush component then moves to the end of the discharge component and works in conjunction with it. The brush component moves to the other end of the discharge component, while the discharge component begins to rotate. The direction and speed of the discharge component's spiral drive are consistent with the direction and speed of the brush component's movement. This allows the brush component to gradually sweep across the surface of the discharge component during its movement, thus cleaning the discharge component. Finally, the drying mechanism dries the inside of the chamber to ensure that no liquid remains on the surface of the discharge components, thus preventing short circuits caused by liquid residue when the discharge components are working. This solution utilizes a spraying mechanism and a brushing mechanism to clean the surface of the discharge components, making it less prone to being covered by dirt. Furthermore, the spraying mechanism can also spray and rinse residual particles on the inner wall of the chamber, thus cleaning the inner wall and maintaining the purification effect of the oil fume and dust-laden exhaust gas separation and purification device at a good level.

[0006] Preferably, the brush component includes a rod and bristles distributed on both sides of the rod facing the discharge component and away from the discharge component.

[0007] Using the above scheme, after the brush component moves to the other end of the discharge component and the bristles detach from the discharge component, it begins to move in the opposite direction. At the same time, the discharge component begins to rotate in the opposite direction. At this time, the brush component can brush the discharge component from the other side to achieve a more comprehensive cleaning effect.

[0008] Preferably, the brushing mechanism includes a slide that cooperates with the drive assembly, a brush component that is flipped and mounted on the slide, and a storage area for storing the brush component is formed inside the housing.

[0009] Using the above solution, the brush component only needs to be unfolded during self-cleaning. When the discharge component is in working condition, the brush component is located in the storage area, which can prevent a large amount of splashed particles from adhering to the brush component.

[0010] Preferably, the brush component is hinged to the slide block and a drive structure is provided between them to drive the brush component to flip. The drive structure includes a slider that is guided and slidably disposed on the slide block, a connecting rod that is hinged to the slider and the brush component at both ends respectively, and a drive member that drives the connecting rod to drive the brush component to unfold or fold.

[0011] Preferably, the slide block is provided with a guide groove for guiding the slider to slide, and the driving component includes an elastic element disposed between the end of the guide groove and the slider, and an electromagnet disposed at the same end as the elastic element.

[0012] Preferably, the drive assembly includes a lead screw transmission structure disposed on the outer wall of the housing and a motor component connected to the lead screw transmission structure. The slide is configured to cooperate with the lead screw transmission structure. An opening is provided on the housing for the slide to partially extend into the housing. A sealing brush is disposed on the inner wall of the housing at the opening.

[0013] By adopting the above solution, the sealing brush can prevent the particles ejected by the discharge component from splashing into the lead screw structure, thus preventing the particles from adhering to the lead screw and guide rod and affecting the movement of the slide.

[0014] Preferably, the drive assembly is located on the top of the housing, and a protective cover is provided on the outside of the drive assembly.

[0015] The above solution takes into account the potential pollution in the air of the environment where the oil fume and dust-containing exhaust gas separation and purification device is used. The protective cover can prevent the screw structure from contacting the external environment.

[0016] Preferably, the spraying mechanism includes a water tank fixedly mounted on the housing, a water pump connected to the water tank, a water pipe located at the output end of the water pump and connected to the housing, and a spray nozzle component located at the end of the water pipe.

[0017] Preferably, the drying mechanism includes a hot air blower mounted on the chamber, with the output end of the hot air blower connected to the chamber. This utility model has significant technical effects due to the adoption of the above technical solutions: This solution uses a spraying mechanism and a brushing mechanism to clean the surface of the discharge component, making it less likely for the surface of the discharge component to be covered by dirt, and keeping the purification effect of the oil fume and dust-containing exhaust gas separation and purification device at a good level.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0020] Example A device for separating and purifying oily fume and dusty exhaust gas, based on Figure 3 As shown, the device includes a housing 1, inside which are sequentially arranged an electrocoagulation zone 2, a rotating, spirally arranged discharge component 3, and an electrostatic adsorption zone 4. The discharge component 3 includes a self-rotating spindle 301, on which are arranged a plurality of discharge electrodes 302, which are spirally distributed around the spindle 301. The end of each discharge electrode 302 is connected to a spiral blade frame 303. An oil drain trough 101 is provided at the bottom of the housing 1. The above structure and its working principle can be referred to the technical solution disclosed in Chinese Patent No. CN218452286U, entitled "Oil Fume Exhaust Gas Purification Device", so it will not be described in detail in this embodiment. In this embodiment, the rotation of the spindle 301 of the discharge component 3 is controlled by a servo motor. The servo motor has the function of resetting to the origin. The servo motor and its reset function are existing technologies, and their principles will not be described in detail in this embodiment.

[0021] The improvement in this embodiment is that a self-cleaning module is provided on the housing 1, according to... Figures 1-3As shown, the self-cleaning module includes a spraying mechanism for spraying cleaning fluid onto the surface of the discharge component 3 and the inner wall of the housing 1. The spraying mechanism includes a water tank 5 fixedly mounted on the housing 1, a water pump 6 connected to the water tank 5, a water pipe 7 at the output end of the water pump 6, the end of the water pipe 7 connected to the inside of the housing 1, and a nozzle component 701 at the end of the water pipe 7. The nozzle component 701 can spray cleaning fluid onto the surface of the discharge electrode 302 and the blade frame 303, as well as the inner wall of the housing 1.

[0022] The self-cleaning module also includes a brushing mechanism for brushing the surface of the discharge component 3, according to Figures 3-6 As shown, the brushing mechanism includes a brush component 8 that can move to cooperate with the discharge component 3 and reciprocate along the transmission direction of the discharge component 3. In this embodiment, the servo motor will first reset the discharge component 3, that is, the discharge component 3 will remain at the same position and angle each time it is self-cleaned. The brush component 8 only needs to move to the designated position to cooperate with the discharge component 3. The brush component 8 includes a rod 801 and bristles 802 distributed on both sides of the rod 801 facing the discharge component 3 and away from the discharge component 3, respectively.

[0023] The movement of brush component 8 is controlled by the drive assembly, according to Figure 1 As shown, in this embodiment, the drive assembly includes a screw drive structure disposed on the top of the housing 1. The screw drive structure includes a pair of mounting seats 9 fixed on the housing 1. A rotatable ball screw 10 and a guide rod 11 disposed parallel to the ball screw 10 are disposed between the two mounting seats 9. The rotation of the ball screw 10 is controlled by a motor component 12. As shown in the figure, a slide 13 is provided on the ball screw 10 and the guide rod 11 for guiding and cooperating. An opening 14 is provided on the housing 1 for the slide 13 to partially extend into the housing 1. A sealing brush 15 is provided on the inner wall of the housing 1 at the opening 14. A protective cover 16 is provided on the outside of the drive assembly. The brush component 8 is flipped onto the slide 13, according to... Figures 7-10 As shown, in this embodiment, a guide groove 17 is provided on the slide block 13, and a slider 18 is guided and slidably disposed in the guide groove 17. A connecting rod 19 is provided between the rod body 801 of the brush component 8 and the slider 18, with its two ends respectively hinged to the rod body 801 and the slider 18. An elastic element 20 is provided between the end of the guide groove 17 and the slider 18. The elastic element 20 can push the slider 18 and the connecting rod 19 to drive the brush component 8 to unfold. An electromagnet 21 is provided at the end of the guide groove 17. When the electromagnet 21 is energized, the magnetic attraction force pulls the slider 18 and the connecting rod 19 to drive the brush component 8 to fold and retract. In this embodiment, the elastic element 20 is a spring disposed between the slider 18 and the inner wall of the guide groove 17. A spring clearance groove 22 is recessed around the electromagnet 21 for installing the spring. When the electromagnet 21 and the slider 18 are attracted, the spring is compressed in the clearance groove 22. according to Figures 3-5 As shown, a partition 23 protrudes from the inside of the housing 1. The partition 23 and the inner wall of the housing 1 form a storage area for storing the brush component 8. The partition 23 can block the particles thrown out when the discharge component 3 rotates at high speed, preventing the brush component 8 from being contaminated. When the discharge component 3 is working, the brush component 8 can be flipped and folded and stored in the storage area. When self-cleaning, the brush can be moved out of the storage area and then unfolded to brush the discharge component 3. The chamber 1 is also equipped with a drying mechanism, according to Figure 1 , 2 As shown, the drying mechanism includes a hot air blower 24 mounted on the housing 1. The output end of the hot air blower 24 is connected to the inside of the housing 1. The specific structure of the hot air blower 24 can be referred to the technical solution disclosed in Chinese Patent No. CN214172554U, entitled "High-efficiency energy-saving electric hot air blower". The electric hot air blower includes a housing, a heating mechanism and a blower mechanism. An air outlet is provided on the housing 1, and a filter screen is provided at the air outlet.

[0024] Based on the above structure, refer to Figures 1-10 It can be seen that the self-cleaning steps of the oil fume and dust-laden exhaust gas separation and purification device in this embodiment are as follows: First, the power supply to the discharge electrode 302 on the discharge component 3 is cut off, and the spray component is activated to spray the surface of the discharge component 3 and the inner wall of the box 1. In the second step, the servo motor resets the discharge component 3. At the same time, the brush component 8 moves out of the storage area to one end of the discharge component 3. Then the electromagnet 21 is de-energized, and the spring drives the brush component 8 to unfold, so that the brush component 8 cooperates with the discharge component 3. Third, the brush component 8 moves to the other end of the discharge component 3, and at the same time the discharge component 3 begins to rotate slowly and the transmission direction and transmission speed of the blade frame 303 are consistent with the moving direction and moving speed of the brush component 8. Fourth step: When the brush component 8 moves to the other end of the discharge component 3 and the bristles 802 detach from the discharge component 3, it begins to move in the opposite direction. At the same time, the discharge component 3 begins to rotate in the opposite direction. The transmission direction and transmission speed of the blade frame 303 are still consistent with the moving direction and moving speed of the brush component 8. Fifth step: After several brushing steps in the third and fourth steps, the brush component 8 moves to one end of the discharge component 3 near the storage area. Then, the electromagnet 21 is energized to drive the brush component 8 to fold and retract, and move into the storage area. In the final step, the hot air blower 24 is started to dry the remaining liquid inside the box 1. 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.
