[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1 and Figure 2 , the utility model provides an embodiment: an LH combined low-temperature electrostatic oil removal device, including a column 1, a filter screen 3 is fixedly connected to the middle of the inner side of the column 1, a rotating rod 4 is rotatably connected to the left side of the filter screen 3, a cross scraper 5 is fixedly connected to the right end of the outer wall of the rotating rod 4, a plurality of connecting rods 6 are fixedly connected to the middle of the outer wall of the rotating rod 4 at equal intervals, an arc scraper 7 is fixedly connected to one end of the connecting rod 6, an impeller 8 is fixedly connected to the left end of the rotating rod 4, the lengths of the plurality of arc scrapers 7 are matched with the size of the left side of the inner wall of the column 1, the size of the cross scraper 5 is matched with the diameter of the filter screen 3, a disassembly mechanism 2 is arranged on the right side of the inner side of the column 1, and a support seat 18 is arranged on the left and right sides of the bottom of the column 1;

[0028] Specifically, the impeller 8 can rotate with the inflow of oil-containing gas. This design enables the impeller 8 to effectively remove impurities adhered to the surface of the filter 3 in the process of driving the rotating rod 4 to rotate. In this way, the filter 3 is not easy to be blocked, thereby reducing the frequency of cleaning the filter 3 and reducing the workload of the staff. On the rotating rod 4, the designer cleverly installed a cross scraper 5. The function of this cross scraper 5 is to scrape the surface of the filter 3 to ensure the cleanliness of the filter 3. In this way, the equipment can always maintain an efficient filtering effect during operation. In addition, the connecting rod 6 on the rotating rod 4 is also responsible for driving the arc scraper 7 to rotate. The purpose of the design of this arc scraper 7 is to scrape the inner wall of the column 1. In this way, the interior of the column 1 can be kept clean, avoiding equipment failure caused by the accumulation of impurities. It not only reduces the workload of the staff and increases the service life of the equipment, but also meets the needs of modern industry for high efficiency, environmental protection and energy saving.

[0029] Reference Figure 2 and Figure 3 The disassembly mechanism 2 includes an activated carbon layer 201, which is arranged on the right side of the inner part of the column 1. A hole 202 is opened on the top of the activated carbon layer 201. A spring 203 is fixedly connected to the inner bottom of the hole 202. The top of the spring 203 is fixedly connected to a limit rod 204. The top of the limit rod 204 passes through the column 1. The upper and lower sides of the inner part of the column 1 are fixedly connected to support columns 205. The adjacent ends of the support columns 205 are fixedly connected to the pole plates 206.

[0030] Specifically, when the service life of the activated carbon layer 201 expires, the limit rod 204 is pressed, and the squeezing force of the spring 203 will drive the limit rod 204 to enter the hole 202. This action will release the limit fixation of the activated carbon layer 201, making it simple and easy to disassemble and replace the activated carbon layer 201, which can reduce the difficulty of users in maintaining and replacing the activated carbon layer 201, making the filtering device more practical.

[0031] Reference Figure 1 and Figure 2 The right side of the column 1 is fixedly connected with an air pump 9, the output end of the air pump 9 is connected with an air outlet pipe 10, the input end of the air pump 9 passes through the column 1 and is connected with an air extraction pipe 11, the left end of the column 1 is connected with a connecting pipe 12, the air pump 9 is electrically connected to an external controller, the top left side of the column 1 is fixedly connected with a refrigeration unit 17, the output end of the refrigeration unit 17 passes through the column 1, and the refrigeration unit 17 is electrically connected to the external controller;

[0032] Specifically, the air pump 9 can be used to conveniently pump the oil-containing gas in the factory exhaust pipe into the column 1 for purification, the refrigeration unit 17 can be used to cool the oil-containing gas entering the column 1, and the operation of the air pump 9 and the refrigeration unit 17 can be controlled by an external controller.

[0033] Reference Figure 1 A movable plate 13 is provided at the front side of the column 1, a rotating shaft 14 is provided at the bottom of the movable plate 13, the movable plate 13 is rotatably connected to the bottom of the column 1 through the rotating shaft 14, a limiting plate 15 is fixedly connected to the top of the front side of the movable plate 13, a latch 16 is provided at the top of the limiting plate 15, and the bottom end of the latch 16 passes through the limiting plate 15 and the column 1 in sequence;

[0034] Specifically, pulling out the latch 16 can release the limit on the limit plate 15 , and then the movable plate 13 can be opened to perform maintenance work on the internal components of the column 1 .

[0035] Working principle: when using the column 1, first connect the factory exhaust pipe to the connecting pipe 12, then start the air pump 9 to pump the oil-containing gas in the factory exhaust pipe into the column 1, and then start the refrigeration unit 17 to cool the oil-containing gas, which can accelerate the solidification of grease and the separation of solid and liquid, making it easier to remove the grease, and the impeller 8 will rotate with the inflow of oil-containing gas, thereby driving the rotating rod 4 to rotate, and the cross scraper 5 on the rotating rod 4 will scrape off the impurities adhered to the surface of the filter 3, and the connecting rod 6 on the rotating rod 4 will also drive the arc scraper 7 to rotate to scrape off the inner wall of the column 1, the filter 3 is not easy to be blocked, and the staff does not need to frequently clean the filter 3, thereby reducing the workload of the staff. To meet the needs of users, the gas filtered by the filter 3 will enter the right side of the column 1. At this time, the electrode 206 is opened. Since the electrode plates 206 on the upper and lower sides are respectively the positive and negative electrode plates 206, the high-voltage electrostatic field generated by the two electrode plates 206 causes the oil-containing gas to be ionized, decomposed, adsorbed and carbonized under the electrostatic field, and finally discharged to the outside after being filtered through the activated carbon layer 201, which can further increase the gas cleaning effect. In addition, the activated carbon layer 201 needs to be replaced after long-term use. At this time, the limit rod 204 is pressed, and the squeezing force of the spring 203 will drive the limit rod 204 to enter the hole 202, thereby releasing the limit fixation of the activated carbon layer 201, and it is relatively simple to disassemble and replace the activated carbon layer 201, thereby improving the practicality of the device.
