Description

Technical Field

[0001] This utility model relates to the technical field of oil fume purification equipment, and in particular to an oil fume purification equipment with automatic cleaning function. Background Technology

[0002] Oil fume purification equipment refers to devices used to treat oily fumes and exhaust gases. It is primarily used to purify oily fumes emitted at low altitudes from kitchens, thereby improving air quality. It is widely used in the catering, food processing, and chemical industries, especially in hotels, restaurants, eateries, schools, government offices, and factories.

[0003] After prolonged fume purification, oil stains typically adhere to the filter elements of oil fume purification equipment due to the adhesive nature of the oil. For example, the filter electric field, after extended filtration, accumulates a significant amount of oil on its plates, impacting the overall purification efficiency. To maintain optimal efficiency, the electric field plates usually need cleaning. However, this is typically done manually, which is inefficient and time-consuming. Therefore, improving the cleaning efficiency of fume purification equipment to save users time and effort is a crucial design challenge for equipment with automatic cleaning capabilities.

[0012] In this technical solution, a support frame supports the filtration electric field, which filters and purifies the oil fumes. A wireless communication module is installed in the electrical control box. Through the wireless communication module, various data during the purification process, including cleaning data, water data, and power consumption data, are uploaded to the cloud server in real time. This allows users to monitor the equipment's operating status anytime, anywhere, and understand the equipment's working condition in a timely manner. At the same time, the uploaded data also provides an important basis for subsequent data analysis and optimization, which helps to further improve the product's performance and quality.

[0013] Preferably, a fixed housing and two water inlet pipes are fixedly connected to the side wall of the water tank, the two water inlet pipes are located on both sides of the fixed housing, a partition plate is fixedly connected to the inner side wall of the water tank, and the middle of the bottom side wall of the water tank is recessed inward.

[0014] In this technical solution, the partition plate divides the interior of the water tank into two cavities. Cleaning agent and clean water can be added to the cavity on the left side of the partition plate through the water pipe on the left side. The cleaning agent and clean water mix to form a cleaning solution. Clean water can be added to the cavity on the right side of the partition plate through the water pipe on the right side.

[0015] Preferably, the water passage structure includes a third water passage pipe, a fourth water passage pipe, a fifth water passage pipe, and a water pump.

The float plate is fixedly connected to the side wall of the second water pump pipe. The sealing ring is fixedly connected to the bottom side wall of the second water pump pipe and the float plate.

[0018] In this technical solution, as the cleaning fluid in the cavity gradually decreases, the float will descend with the drop in water level, and the telescopic pipe will also extend downward under the action of gravity. When the cleaning fluid in the cavity is used up, the sealing ring at the bottom of the second pumping pipe will adhere to the inner wall of the bottom of the water tank, thus blocking the lower end of the second pumping pipe.

[0019] Preferably, two limiting rods are slidably connected to the side wall of the float plate, the bottom of the two limiting rods are fixedly connected to the bottom side wall of the water tank, and the top of the two limiting rods are respectively fixedly connected to the top inner side wall of the water tank and the side wall of the water pipe.

[0020] In this technical solution, the limiting rod ensures that the float can only float up and down.

[0021] Preferably, the piston structure includes a rotating gear, a rotating block, a threaded rod, a piston block, and a sealing gasket.

The rotating gear on the left then drives the rotating gear on the right to rotate, with the right rotating gear rotating in the opposite direction. The rotating gear on the right then drives the threaded rod on the right to rotate, which in turn causes the piston block and sealing gasket on the right to descend, thus opening the fourth water pipe on the right.

[0024] Preferably, the cleaning structure includes a fixed column, linear guide rails, and a movable rod. The fixed column is fixedly connected to the top inner wall of the oil fume purification equipment housing. Two linear guide rails are fixedly connected to the bottom of the fixed column, and a movable rod is fixedly connected between the sliders on the two linear guide rails.

[0025] In this technical solution, the linear guide rail drives the moving rod to move, and the moving rod drives the spray pipe to move, so that the cleaning liquid is evenly sprayed onto the filter electric field below.

[0026] Preferably, the cleaning structure includes a spray pipe, a connecting pipe, a connecting shell, a connecting block, a first water pipe, a second water pipe, and a third water pipe.

[0028] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0029] The positive and progressive effects of this utility model are as follows:

[0030] 1. As the cleaning fluid in the left cavity gradually decreases, the float will descend with the drop in water level, and the telescopic pipe will also extend downward under gravity. When the cleaning fluid in the cavity is used up, the sealing ring at the bottom of the second water pump will adhere to the inner wall of the bottom of the water tank, thus blocking the lower end of the second water pump. With the suction of the water pump, a negative pressure will be generated in the water passage cylinder on the left side of the partition plate, which will drive the piston block and sealing gasket on the left side to rise, thus blocking the bottom of the fourth water passage on the left side. The rise of the piston block on the left side will drive the piston block and sealing gasket on the right side to fall, thus opening the fourth water passage on the right side. This allows for better automatic replacement with clean water for rinsing after the cleaning fluid is used up, through the piston structure.

[0031] 2. The cleaning solution is drawn from the water tank by a water pump and then enters the spray pipe through water pipe two, water hose, water pipe one, and connecting pipe. The linear guide rail drives the spray pipe to move, so that the cleaning solution is evenly sprayed onto the filter electric field below to clean the oil stains on the filter electric field. After the cleaning solution is used, the piston structure automatically replaces the solution with clean water for cleaning. The spray pipe sprays clean water downwards to rinse the filter electric field of any remaining cleaning solution. This facilitates automatic cleaning of the filter electric field inside the fume purification equipment, improves cleaning efficiency, and saves users time and effort. Attached Figure Description

[0049] The water pump 915 draws the cleaning fluid from the water tank 8 through the water pipe 914, water pipe 913, water cylinder 912, water pipe 911, water pipe 901, telescopic pipe 902 and water pipe 903.

[0050] The water passage structure 9 includes a first water intake pipe 901, a telescopic pipe 902, a second water intake pipe 903, a float plate 904, and a sealing ring 905. The first water intake pipe 901 is fixedly connected to the inner top wall of the water tank 8. The side wall of the first water intake pipe 901 is fixedly connected to the end of the third water passage pipe 911. The bottom of the first water intake pipe 901 is fixedly connected to the telescopic pipe 902. The bottom of the telescopic pipe 902 is fixedly connected to the second water intake pipe 903. The float plate 904 is fixedly connected to the side wall of the second water intake pipe 903. The sealing ring 905 is fixedly connected to the bottom side walls of the second water intake pipe 903 and the float plate 904.

[0051] As the cleaning fluid in the cavity gradually decreases, the float 904 will descend with the drop in water level, and the telescopic pipe 902 will also extend downward under the action of gravity. When the cleaning fluid in the cavity is used up, the sealing ring 905 at the bottom of the second water pump pipe 903 will adhere to the bottom inner wall of the water tank 8, thus blocking the lower end of the second water pump pipe 903.

[0052] Two limiting rods 921 are slidably connected to the side wall of the float 904. The bottom of the two limiting rods 921 is fixedly connected to the bottom side wall of the water tank 8, and the top of the two limiting rods 921 is fixedly connected to the top inner side wall of the water tank 8 and the side wall of the water pipe 911, respectively.

[0053] The limiting rod 921 allows the float 904 to float only up and down.

The rotating gear 1201 on the left drives the rotating gear 1201 on the right to rotate. The rotating gear 1201 on the right rotates in the opposite direction to the rotating gear 1201 on the left. The rotating gear 1201 on the right drives the threaded rod 1203 on the right to rotate. The rotation of the threaded rod 1203 causes the piston block 1204 and sealing gasket 1205 on the right to descend, opening the water pipe 913 on the right.

[0057] The cleaning structure 7 includes a fixed column 711, a linear guide rail 712, and a moving rod 713. The fixed column 711 is fixedly connected to the top inner wall of the oil fume purification equipment housing 1. Two linear guide rails 712 are fixedly connected to the bottom of the fixed column 711. A moving rod 713 is fixedly connected between the sliders on the two linear guide rails 712.

[0058] The linear guide rail 712 drives the moving rod 713 to move, and the moving rod 713 drives the spray pipe 701 to move, so that the cleaning liquid is evenly sprayed onto the filter electric field 2 below.

[0059] The cleaning structure 7 includes a spray pipe 701, a connecting pipe 702, a connecting shell 703, a connecting block 704, a first water pipe 705, a second water pipe 706, and a third water pipe 707. The connecting block 704 is fixedly connected to the side wall of the moving rod 713. The connecting shell 703 is rotatably connected to the side wall of the connecting block 704. The connecting shell 703 is internally threaded with the connecting pipe 702. The bottom of the connecting pipe 702 is fixedly connected to the spray pipe 701.

The other end of the second water pipe 706 is fixedly connected to the second water pipe 707. The other end of the second water pipe 707 is fixedly connected to the outlet of the water pump 915.

[0060] The cleaning solution then enters the spray pipe 701 through water pipe 2 707, water hose 706, water pipe 1 705 and connecting pipe 702, and is sprayed downward through the nozzle on the spray pipe 701.

[0061] In use, all electrical components mentioned in this application are connected to an external power supply and control switch. The partition plate 13 divides the interior of the water tank 8 into two cavities. Cleaning agent and clean water can be added to the cavity on the left side of the partition plate 13 through the water pipe 705 on the left side. The cleaning agent and clean water are mixed to form a cleaning solution. Clean water can be added to the cavity on the right side of the partition plate 13 through the water pipe on the right side.

[0062] When cleaning of the filter electric field 2 is required, the water pump 915 is started by controlling the electrical control box 14.

The cleaning liquid then enters the spray pipe 701 through the water pipe 2 707, water hose 706, water pipe 1 705 and connecting pipe 702. The cleaning liquid is sprayed downward through the nozzle on the spray pipe 701. The linear guide rail 712 drives the moving rod 713 to move, and the moving rod 713 drives the spray pipe 701 to move, so that the cleaning liquid is evenly sprayed onto the filter electric field 2 below to clean the oil stains on the filter electric field 2.

[0063] The wastewater from the cleaning process falls into the water receiving tank 5 below and is discharged through the water outlet pipe 6. As the cleaning fluid in the cavity gradually decreases, the float 904 will descend with the drop in water level, and the telescopic pipe 902 will also extend downward under the action of gravity. When the cleaning fluid in the cavity is used up, the sealing ring 905 at the bottom of the second water pump pipe 903 adheres to the bottom inner wall of the water tank 8, thus blocking the lower end of the second water pump pipe 903. At this time, with the suction of the water pump 915, a negative pressure is generated in the water passage cylinder 912 on the left side of the partition plate 13. Under the negative pressure, the piston block 1204 and the sealing gasket 1205 are driven to rise, thus blocking the bottom of the fourth water passage pipe 913.

[0064] The piston block 1204 rises, causing the threaded rod 1203 on the left to rotate. The threaded rod 1203 drives the rotating gear 1201 on the left to rotate via the rotating block 1202. The rotating gear 1201 on the left drives the rotating gear 1201 on the right to rotate. The rotating gear 1201 on the right rotates in the opposite direction to the rotating gear 1201 on the left. The rotating gear 1201 on the right drives the threaded rod 1203 on the right to rotate. The rotation of the threaded rod 1203 causes the piston block 1204 and the sealing gasket 1205 on the right to descend, causing the water pipe 913 on the right to open. The piston structure 12 can automatically replace the cleaning fluid with clean water for rinsing after the cleaning fluid is used up.

[0065] This allows the clean water in the cavity on the right side of the partition plate 13 to be extracted and sprayed downwards through the spray pipe 701 to rinse the residual cleaning liquid on the filter electric field 2. This facilitates automatic cleaning of the filter electric field 2 inside the fume purification equipment, improving cleaning efficiency and saving users time and effort.
