Description
Technical Field
The invention relates to the technical field of outward flow filtering devices, in particular to a filtering method.
Background
Computers are common electronic products in life, and the cooling method of the computer case is also continuously improved and advanced; the prior art provides a new method for cooling a computer case, namely oil cooling; the principle of oil cooling is that the whole main board including the display card is soaked in the transformer oil, and compared with air cooling and water cooling modes, the oil cooling can almost omit all fans on a case, so that the transformer oil has high heat dissipation efficiency and is more insulated than air; and noise can be reduced. With the popularization of the technology, the recycling and filtering of the transformer oil also become more important problems for current manufacturers.
The duplex filter is also called as a duplex switching filter, is formed by connecting two stainless steel filters in parallel, and has the advantages of novel and reasonable structure, good sealing property, strong circulation capacity, simple and convenient operation and the like. Particularly, the filter bag has small side leakage probability, thereby not only ensuring the filtering precision, but also being capable of rapidly replacing the filter bag.
Liquid materials in many fields need to be filtered of impurities by a duplex filter, as follows: weakly corrosive materials in petrochemical production, such as: water, ammonia, oils, hydrocarbons, and the like. Corrosive materials in chemical production, such as: caustic soda, concentrated and diluted sulfuric acid, carbonic acid, acetic acid, and the like. Cryogenic materials in refrigeration, such as: liquid methane, liquid ammonia, liquid oxygen and various refrigerants. Materials with sanitary requirements in the production of light industrial foods and pharmacy, such as: beer, beverage, dairy products, grain and pulp medical supplies and the like. Therefore, the transformer oil (hereinafter referred to as oil) can be recovered and filtered by using the duplex filter.
The duplex filter is generally in a shape that the outermost layer is a stainless steel cover and the inside is a 40-mesh stainless steel filter screen, so that in order to improve the product quality and continuously meet and exceed the requirements of customers, enterprises can filter impurities in materials by using 120-mesh filter bags on the inner side of the stainless steel filter screen; if the stainless steel filter screen is directly replaced by 120 meshes, on one hand, the filter screen with large mesh number is very expensive in cost and not easy to clean and maintain, and on the other hand, the equipment is not suitable for producing products with large granularity and cannot meet the requirement of diversified production of the equipment. Therefore, the purpose of using the filter bag is to increase the filter mesh number and improve the product quality, and the filter bag is adopted to facilitate the cleaning of filter residue.
The prior art has the following technical problems: the filter bag is fixed mainly by the occlusion of the convex eaves between the duplex filter shell and the edge of the stainless steel filter screen, and because the fluid can generate larger pressure at the moment of leading into the filter bag, the occluded part of the filter bag is often broken to form a cave, and the filter bag needs to be frequently replaced with new one, the current situation not only can cause great waste, but also can cause hidden troubles in product quality, and also seriously affects the filtration efficiency.
Disclosure of Invention

step two, mounting a filter bag: preparing a filter device which comprises a hard filter barrel, a filter bag and a clamp for clamping the edge of the filter bag; the hard filter barrel is provided with a U-shaped groove, a rotating shaft, a blade positioned on the rotating shaft and a supporting plate driven by the blade, and the end part of the rotating shaft is provided with a rotating handle; putting the filter bag into a hard filter vat; then, curling the edge of the filter bag outwards to enable the curled edge to be attached to the edge of the hard filter barrel, and then rotating the clamp to clamp the edge of the filter bag; simultaneously, curling the side walls around the U-shaped opening so that the side walls of the U-shaped groove are wrapped by the curled edges;
step three, fine filtration: adding the oil in the step one into the filter bag, and simultaneously impacting the blades, wherein the blades drive the supporting plate to move upwards so as to push the bottom of the filter bag upwards; and stopping introducing the oil into the filter bag after the amount is reached, and starting filtering.
The beneficial effect that this scheme produced is:
the oil is added into the filter bag by adopting the method in the third step, so that the phenomenon that the occlusion part of the filter bag is broken to form a small hole due to the large pressure generated at the moment when the flowing oil is introduced into the bottom of the filter bag can be prevented. When oil impacts blades on the rotating shaft, the blades rotate, the blades drive the supporting plate to move upwards, and then the bottom of the filter bag is pushed upwards, so that before the oil impacts the bottom of the filter bag, the bottom of the filter bag is pushed upwards by the supporting plate, and flowing oil cannot generate large pressure at the moment of being introduced to the bottom of the filter bag, so that the occluded part of the filter bag is often broken to form a small hole; the filter bag does not need to be frequently replaced with a new one. In addition, the method is adopted to filter the oil, when the oil enters the filter bag, the filter bag floats under the action of the supporting plate, and the charging and filtering efficiency can be improved.
The first preferred scheme is as follows: and (3) as a further optimization of the basic scheme, heating the oil after coarse filtration in the step one to 60-70 ℃, and then repeating the thermal cycle for 7-11 times. The oil (transformer oil) is circulated at the temperature, so that oil aging products in the oil can be dissolved; and the water in the oil can be evaporated after heating, and then the water in the oil can be removed.
The preferred scheme II is as follows: as a further optimization of the first preferred scheme, cooling the oil circulated in the first step to 50-60 ℃; then adding silica gel into the oil, and removing water from the oil; then the oil is introduced into the feed pipe in step three. Silica gel is used to further ensure that water in the oil is sucked out.
The preferable scheme is three: as a further optimization of the second preferred scheme, the silica gel is wrapped into a bag shape by adopting alkali-free glass fiber cloth or fine sand cloth and then put into the oil. Prevent the silica gel from scattering in the oil and being taken out difficultly.
The preferable scheme is four: as a further optimization of the third preferred scheme, the rotating handle in the third step is held, and the rotating handle is rotated again, so that the supporting plate moves upwards; then the rotating handle is loosened, and the supporting plate moves downwards to restore the original position; repeating the steps, and vibrating the bottom of the filter bag. Further ensuring the filtering efficiency and preventing the sediment from accumulating to the bottom of the filter bag.
The preferable scheme is five: and as a further optimization of the preferable scheme IV, the rotary handle in the step III is held for rotation every 1-2 hours, and the bottom of the filter bag is vibrated. Further ensuring the filtering efficiency and preventing the sediment from accumulating to the bottom of the filter bag.
