[0002] Oil fume purification equipment is an oil fume waste gas treatment device, which is mainly used for the purification of oil fume discharged from the kitchen. It is used in hotels, restaurants, shopping malls, factories and other places to make the purified gas meet the oil fume emission standards.

[0003] Oil fume purification equipment generally includes a shell and a purification unit arranged in the shell. The purification unit is an electrostatic purifier. The oil fume exhaust gas enters the shell through the air inlet of the shell. When the airflow enters the electrostatic purifier, under the action of the high-voltage electric field, the oil fume gas is ionized and the oil mist is charged, so that it is adsorbed on the electrode plate to purify the flue gas. After the oil fume purification equipment has been working for a period of time, some oil fume will adhere to the electrode plate and the inner wall of the shell to form oil stains, which need to be cleaned regularly to ensure its flue gas purification effect. Most of the existing cleaning methods are manual cleaning, which requires the electrostatic purifier to be disassembled and taken out of the equipment for cleaning, and the inner wall of the shell to be rinsed. Manual cleaning is inefficient and cumbersome to operate.

[0004] It can be seen that the existing technology still needs to be improved and enhanced. Summary of the invention

DETAILED DESCRIPTION

[0025] The present invention provides an oil fume purification device with a cleaning function. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0026] See also Figures 1 to 6 As shown, the present invention provides an oil fume purification device with a cleaning function, comprising a casing 1, a purification unit 2, a fixed flow averaging net 3, a dynamic flow averaging net 4 and a translation mechanism 5, the corresponding two side walls of the casing 1 are respectively provided with an air inlet 11 and an air outlet 12, two fixed flow averaging nets 3 are respectively provided on the air inlet 11 and the air outlet 12, the dynamic flow averaging net 4 can be horizontally slidably provided on the fixed flow averaging net 3, the translation mechanism 5 is provided on the casing 1, the output end of the translation mechanism 5 is connected to the dynamic flow averaging net 4, a plurality of first ventilation holes 31 are provided on the fixed flow averaging net 3, and a second ventilation hole 41 is provided on the dynamic flow averaging net 4, the translation mechanism 5 drives the dynamic flow averaging net 4 to move, so that all the first ventilation holes 31 and the second ventilation holes 41 are staggered with each other, or all the first ventilation holes 31 and the second ventilation holes 41 overlap, and a steam inlet 6 is provided on the side of the casing 1.

[0027] During the fume purification process, the first ventilation hole 31 and the second ventilation hole 41 overlap, so that the fume enters the casing 1 evenly through the air inlet 11, and passes through the purification unit 2 for fume purification, and finally the purified fume is discharged from the air outlet 12. After working for a period of time, part of the oil fume adheres to the plate of the purification unit 2 and the inner wall of the casing 1 to form oil stains. When cleaning is required, the two translation mechanisms 5 drive the two moving flow nets 4 to move a distance respectively, and the first ventilation hole 31 and the second ventilation hole 41 are staggered to close the air inlet 11 and the air outlet 12, so that a closed space is formed inside the casing 1, and then high-temperature steam is filled into the casing 1 through the steam inlet 6. Since the steam contains water, it can dissolve the oil stains adhered to the purification unit 2 and the inner wall of the casing 1. After the oil stains are dissolved, they will automatically flow down along the wall to the bottom of the casing 1, thereby realizing the function of automatically cleaning the fume purification equipment. The whole process does not require the equipment to be disassembled, the operation is simple, and the cleaning efficiency is high.

[0028] In the above, the purification unit 2 can be a cylindrical electrostatic electric field or a plate electrostatic electric field, which utilizes a high voltage electric field to ionize the flue gas and charge the oil mist, thereby being adsorbed on the purification unit 2 to purify the flue gas.

[0029] In the above description, the steam inlet 6 is externally connected to a boiler to enable steam with a certain temperature to be introduced into the steam inlet 6 .

[0030] In a preferred embodiment, see Figure 4 , 5 , all the first ventilation holes 31 are arranged in a matrix on the fixed flow net 3, and two adjacent rows of first ventilation holes 31 are staggered; all the second ventilation holes 41 are arranged in a matrix on the dynamic flow net 4, and two adjacent rows of second ventilation holes 41 are staggered. Through the above arrangement, the smoke passing rate of the fixed flow net 3 and the dynamic flow net 4 is improved, and the dynamic flow net 4 can move left and right under the drive of the translation mechanism 5, so that all the first ventilation holes 31 and the second ventilation holes 41 are switched between overlapping and mutually staggered states. When the first ventilation holes 31 and the second ventilation holes 41 overlap, the oil fume purification device is in a working state of purifying smoke, and when the first ventilation holes 31 and the second ventilation holes 41 are staggered, the oil fume purification device is in an automatic cleaning state.

[0031] In a preferred embodiment, see Figure 3 , 6 The fixed averaging net 3 is provided with a plurality of waist holes 32. In this embodiment, there are six waist holes 32, which are symmetrically arranged. A first nut 42 is fixed on the dynamic averaging net 4. A screw 43 is threadedly connected to the first nut 42. The screw 43 is slidably connected to the waist hole 32. Through the above arrangement, the dynamic averaging net 4 can be installed on the fixed averaging net 3 and can perform translational movement along the length direction of the waist hole 32.

[0032] Further, see Figure 6 , 7 In order to improve the structural stability of the fixed average flow net 3 and the dynamic average flow net 4, flanges 33 are provided around the fixed average flow net 3 and the dynamic average flow net 4. The dynamic average flow net 4 is located on the inner side of the fixed average flow net 3, and the inner surface of the fixed average flow net 3 is in contact with the outer surface of the dynamic average flow net 4. When the first ventilation hole 31 and the second ventilation hole 41 are staggered with each other, the fixed average flow net 3 and the dynamic average flow net 4 are in contact with each other to achieve the purpose of closing the air inlet 11 and the air outlet 12.

[0033] In a preferred embodiment, see Figure 6 The air inlet 11 and the air outlet 12 are both provided with two parallel mounting grooves 7, and the constant flow net 3 is clamped between the two mounting grooves 7. The length of the mounting groove 7 matches the width of the constant flow net 3 to prevent the constant flow net 3 from moving left and right.

[0034] In this embodiment, a cabinet door 9 is hinged on a side wall between the air inlet 11 and the air outlet 12. After the cabinet door 9 is opened, the flow-balancing net 3 can be installed and removed.

[0035] In a preferred embodiment, see Figure 4 , 5 The translation mechanism 5 includes a mounting plate 51 disposed on the outer wall of the housing 1, an electric push rod 52 disposed on the mounting plate 51, and a connecting rod 53 disposed at the output end of the electric push rod 52. The connecting rod 53 drives the dynamic flow-averaging net 4 to move horizontally, that is, the connecting rod 53 extends to the inside of the housing 1 and connects to the dynamic flow-averaging net 4. The electric push rod 52 drives the connecting rod 53 to move horizontally, thereby driving the dynamic flow-averaging net 4 to move horizontally.

[0036] Specifically, any screw 43 on the fixed flow balancing net 3 passes through the end of the connecting rod 53, and the position of the connecting rod 53 is locked by two second nuts 55, so that the connecting rod 53 drives the dynamic flow balancing net 4 to move horizontally.

[0037] Further, see Figure 4 , 5 The translation mechanism 5 further includes an adapter block 54 rotatably connected to the mounting plate 51, and the two ends of the adapter block 54 are respectively hinged to the output end of the electric push rod 52 and the connecting rod 53. The electric push rod 52 is installed vertically to reduce the installation space; the extension rod of the electric push rod 52 moves up and down in the vertical direction to push the adapter block 54 to reciprocate, thereby driving the connecting rod 53 to move horizontally.

[0038] In a preferred embodiment, see Figure 1 , 3The bottom of the housing 1 is provided with a removable oil receiving pan 8, and the bottom of the housing 1 is provided with a first oil discharge port 13 connected to the oil receiving pan 8. The dissolved oil stains slide to the bottom of the housing 1 due to their own weight, and flow to the oil receiving pan 8 through the first oil discharge port 13. The oil receiving pan 8 is provided to collect the oil stains uniformly. In addition, after the oil receiving pan 8 is pulled out, it is convenient to clean the oil receiving pan 8.

[0039] Preferably, a side wall of the oil receiving pan 8 is provided with a second oil drain port 81 , and the second oil drain port 81 can be externally connected to a drain pipe to facilitate draining of the oil in the oil receiving pan 8 .

[0040] In a preferred embodiment, the axis of the steam inlet 6 is parallel to the constant flow net 3 . Preferably, the steam inlet 6 is arranged perpendicular to the cabinet door 9 .

[0041] In practical applications, such as Figure 1 As shown, when the boiler in the working area cannot provide a sufficient amount of steam for the oil fume purification equipment, the steam inlet 6 is set toward the purification unit 2 so that the steam is blown toward the purification unit 2, and the steam can quickly reach the inside of the purification unit 2 to quickly dissolve the oil stains adhering to the plates of the purification unit 2.

[0042] like Figure 2 As shown, when the boiler can provide a sufficient amount of steam for the oil fume purification equipment, the steam inlet 6 is located beside the purification unit 2, so that the steam blows toward the side of the purification unit 2, and the steam can quickly fill the inside of the casing 1 to quickly dissolve the oil stains adhering to the plates of the purification unit 2 and the inner wall of the casing 1, thereby achieving the function of fully cleaning the purification unit 2 and the inner wall of the casing 1.

[0043] In practical applications, there may be multiple steam inlets 6 to increase the speed at which steam fills the interior of the casing 1 .

[0044] In summary, the present invention drives the dynamic flow-averaging net 4 to move horizontally through the translation mechanism 5, so that the first ventilation holes 31 on the fixed flow-averaging net 3 and the second ventilation holes 41 on the dynamic flow-averaging net 4 are switched between mutually staggered and overlapping states. When the first ventilation holes 31 overlap with the second ventilation holes 41, the air inlet 11 and the air outlet 12 are in an open state, and the smoke can enter the interior of the casing 1 through the air inlet 11, and then the smoke purified by the purification unit 2 is discharged from the air outlet 12, and the oil fume purification device is in a working state; When the first ventilation hole 31 and the second ventilation hole 41 are staggered with each other, the air inlet 11 and the air outlet 12 are in a closed state, and a closed space is formed inside the casing 1. At this time, steam is filled into the casing 1 through the steam inlet 6. The steam dissolves the oil stains adhering to the purification unit 2 and the inner wall of the casing 1. The dissolved oil stains flow downward due to their own weight and are discharged through the first oil discharge port 13 located at the bottom of the casing 1, so as to achieve the purpose of automatically cleaning the oil fume purification equipment. The cleaning work is highly efficient, and there is no need to disassemble the purification unit 2, which simplifies the operation.
