Description

Technical Field

[0001] The utility model relates to the field of oil filter equipment, in particular to an oil purification and filtering device. Background Art

[0002] During the forging process, the forging hydraulic press equipment needs to ensure that the oil accuracy level is within the standard range during the forging operation, because when the forging equipment is in continuous production or the ambient temperature is high, the oil is in a non-stop circulation state. When there is water, impurities, etc. in the oil, water and oil will react to a certain extent to generate colloid, sludge, etc. At the same time, water will also reduce the lubrication performance of the oil. At the same time, water will also corrode the metal to a certain extent to accelerate the wear of components and harm the equipment. The sludge in the oil will block the instrument, damage the valve plug filter, etc. Therefore, it is very important to effectively filter the oil in the forging hydraulic press equipment, remove impurities such as sludge and water, and keep the oil in a clean state. It can not only reduce the equipment failure rate and reduce the number of times the lubricating oil is replaced, but also greatly help maintain the use of equipment and maintain the stability of production. Daily oil filtration adopts the traditional filter element filtration method. As the start-up rate of forging equipment increases, the filter element replacement life is shortened. While the cost increases, the replacement will also delay the production progress, and the filter element filtration method alone cannot meet the oil quality grade requirements. Therefore, in order to ensure that the oil grade of the oil forging press is stable and controlled under any circumstances, to prevent equipment abnormalities caused by abnormal oil particle size or excessive grade, and to ensure continuous and stable operation of the equipment, an oil purification and filtration device is needed. The device can realize real-time high-quality circulation filtration and purification of the oil in the oil tank of the forging hydraulic press equipment, extend the service life of the instrument, and ensure orderly production. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an oil purification and filtering device, which can circulate and purify the oil in the oil tank with high quality, ensure the overall oil quality, and prevent abnormal shutdown caused by substandard oil grade.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: an oil purification and filtering device, including an oil tank, an oil outlet is arranged at the bottom of the oil tank, an oil inlet is arranged at the top of the oil tank, the oil outlet of the oil tank is connected to a pre-purification device, the pre-purification device is a filter element, the central oil outlet pipe of the pre-purification device is connected to an electromagnetic adsorption device through a pipeline, the electromagnetic adsorption device includes an electrostatic barrel, an energized collector is arranged in the electrostatic barrel, an electromagnetic generating device is arranged at the bottom of the electrostatic barrel, the oil outlet pipe of the collector is connected to a separator of a normal temperature condensation and separation device through a pipeline, the oil outlet at the top of the separator is connected to the oil inlet of the oil tank through a pipeline, forming a filtering cycle.

[0005] A further improvement of the technical solution of the utility model is that the filter element of the pre-purification device is made of stainless steel and has a filter diameter of 10 μm.

[0006] The further improvement of the technical solution of the utility model is that the collector is cylindrical, the side wall is sealed, a plurality of concentric circle structured baffle plates are arranged in the collector, a collecting plate with a triangular wavy cross section is arranged between every two layers of baffle plates, and a dirt receiving box is arranged at the bottom of the collector.

[0007] A further improvement of the technical solution of the utility model is that the separator is a filter element made of polymer nano material.

[0008] The further improvement of the technical solution of the utility model is that: a rotating platform is arranged at the bottom of the separator, and a drain valve is arranged at the bottom of the oil pipe in the separator.

[0009] Due to the adoption of the above technical scheme, the technical progress achieved by the utility model is: by setting up an electromagnetic adsorption system, using an electrostatic barrel to use pulse charges under the action of a magnetic field, pollutants such as sludge will be charged with "+" and "-" charges, and then they will gather together and grow, and finally they will be adsorbed on the collector after power is turned on. Using the principle of electromagnetic adsorption, impurities of all sizes can be adsorbed, and the adsorption accuracy can reach 0.02μm. By setting a dirt box at the bottom of the collector, the more impurities adsorbed on the collector, the more they will fall into the bottom dirt box due to gravity, so the collector can be used many times. By designing the internal collecting plate of the collector to be closed in a triangular wave, there is a larger contact area with impurity sludge, and the adsorption effect is better. By using polymer nanofibers to make a separator, the water in the oil can be aggregated into water droplets, and the separator can be rotated as a whole with the rotating table at the bottom. By using the different specific gravity of oil and water, the oil can be better transferred to the top and the water can be thrown to the bottom with the rotation, and the water can be discharged with the bottom drain valve, and the water removal effect is better. By connecting the oil outlet at the top of the separator to the oil inlet of the oil tank through a pipe, a filtering cycle can be formed to filter the oil in the tank in real time to ensure that the oil level always meets the standard.

DETAILED DESCRIPTION

[0014] The present invention is further described in detail below in conjunction with the embodiments:

[0015] like Figure 1 As shown, it is a structural schematic diagram of an oil purification and filtering device. The oil tank 1 of the forging hydraulic press equipment is provided with an oil outlet at the bottom and an oil inlet at the top. The oil in the oil tank 1 is led out from the oil outlet by a pump. The oil outlet is connected to the pre-purification device 2 through a pipeline. The pre-purification device is a stainless steel filter element. The main filter material is a multi-layer stainless steel sintered mesh. An oil outlet pipe is provided in the middle for the filtered clean oil to flow out. When in use, the oil drawn from the oil tank is filtered from the outside of the stainless steel filter element through layers of stainless steel sintered mesh by pressure. The filter diameter is 10μm and enters the internal oil outlet pipe. The central oil outlet of the pre-purification device 2 is connected to the electromagnetic adsorption device 3 through a pipeline, and the pre-purified clean oil is introduced into the electromagnetic adsorption device 3 from the oil outlet through a pipeline. The electromagnetic adsorption device 3 includes an electrostatic barrel 32, in which an energized collector 33 is provided, and an electromagnetic generator 31 and an electrostatic generator are provided at the bottom of the electrostatic barrel 32. The collector 33 is cylindrical with sealed sidewalls. Figure 2As shown, the collector 33 is provided with a plurality of concentric circle structure baffles, and a triangular wave-shaped collecting plate is provided between each two layers of baffles. This type of collecting plate has more wrinkles and a larger contact area with impurity sludge, so that the adsorption effect is better. The oil outlet of the pre-purification device 2 is connected to the top of the collector 33 through a pipeline, and the oil inlet direction is from top to bottom. The pulse charge of the electrostatic barrel 32 is used under the action of the magnetic field, which will make the sludge and other pollutants carry "+" and "-" charges, and then they will gather together and increase. The electromagnetic generating device is used to form an electrostatic field on the electrified surface of each layer of the collecting plate in the collector 33. The charged sludge and other pollutants will be adsorbed on the collecting plate. The more pollutants adsorbed on the collecting plate, the more pollutants will fall into the dirt box at the bottom of the collecting plate under the action of gravity, so as to realize the multiple use of the electromagnetic adsorption device 3. The electromagnetic adsorption can adsorb impurities of all sizes, and the adsorption accuracy can reach 0.02μm, which has a good purification and filtration effect on the oil. The oil outlet at the bottom of the collector 33 is connected to the separator 41 of the normal temperature coalescence separation device 4 through a pipeline, and the oil outlet at the top of the separator 41 is connected to the oil inlet of the oil tank 1 through a pipeline, forming a filtering cycle to continuously filter the oil in the oil tank. The separator 41 is a separation filter element made of polymer nanofiber material. Due to the different tensions, the oil passes through the filter element quickly, and the water passes through very slowly. The water droplets settle and separate from the oil under the action of gravity. A rotating table 42 is provided at the bottom of the separator 41. The rotation can better transfer the oil to the top and the water to the bottom. The bottom drain valve 43 is used to remove the water separated from the bottom to achieve the dewatering operation.

[0016] The utility model can realize high-quality filtration and purification, so that the oil grade of the oil forging press is stably controlled and consistent, and equipment abnormalities caused by abnormal oil particle size or grade exceeding the standard are prevented, thereby ensuring continuous and stable operation of the equipment.

[0017] The embodiments described above are merely descriptions of preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
