DETAILED DESCRIPTION

[0014] 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.

[0015] Embodiment: In conjunction with the specification Figure 1-2 It can be seen that in order to solve the problem of maintenance and repair of the hydraulic system of the fracturing truck in the prior art, the hydraulic oil needs to be discharged during the dismantling of the equipment. The hydraulic oil in the equipment is usually of good quality. The discharge of the oil not only causes a waste of resources, but also causes unnecessary pollution to the environment. A hydraulic oil filtration device for repairing the hydraulic system of a fracturing truck is specifically designed. A pumping pump 2 is connected to the lower end of the oil collecting bucket 1, and the discharge end of the pumping pump 2 is connected to the first filter chamber 3. A magnetic separation component is arranged in the first filter chamber 3, and a conical metal filter screen 4 is installed at the lower part of the magnetic separation component. A booster pump 5 is connected to the lower part of the first filter chamber 3, and the discharge end of the booster pump 5 is connected to the second filter chamber 6. A combined filter component is arranged in the second filter chamber 6, and the outlet end of the second filter chamber 6 is connected to the adsorption chamber 7. The adsorption chamber 7 is vertically connected to the filter screen. A multi-stage filler adsorption layer is provided, and a clean oil storage bin 8 is installed at the outlet end of the adsorption bin 7. During the inspection and maintenance of the hydraulic system of the fracturing truck, the hydraulic oil in the hydraulic equipment is collected in the oil collection bucket 1, and the waste hydraulic oil is pumped into the first filter bin 3 through the oil pump 2. The metal debris in the hydraulic oil is magnetically adsorbed by the magnetic separation component arranged in the first filter bin 3. The hydraulic oil after magnetic adsorption is further pressurized by the booster pump 5 and pressed into the second filter bin 6, and the small particle impurities in the hydraulic oil are further filtered and separated. The hydraulic oil after two-stage filtration enters the adsorption bin 7 and flows under the action of gravity. Under the adsorption action of the multi-stage filler adsorption layer, the impurities, particles and harmful substances in the hydraulic oil are adsorbed and purified. The purified hydraulic oil enters the clean oil storage bin 8 and can be reused.

[0016] In the specific implementation process, a mounting frame 9 is provided on the upper part of the above-mentioned first filter bin 3, and a driving member 10 is provided on the mounting frame 9, wherein the magnetic separation component includes a fixed shaft 11 and a magnet rod 12, and the fixed shaft 11 is rotatably inserted in the center position of the cover plate of the first filter bin 3, and the magnet rod 12 is arranged along the circumferential direction of the fixed shaft 11 and is assembled and connected to the side wall of the fixed shaft 11 through a connecting seat, and a propulsion stirring paddle 13 is provided at the lower end of the fixed shaft 11. When in use, the driving member 10 is started, and the driving member 10 is used to drive the fixed shaft 11 to rotate, so that the magnet rod 12 on the fixed shaft 11 stirs the hydraulic oil, thereby magnetically attracting metal debris mixed in the hydraulic oil to the magnet rod 12, thereby improving the quality of the hydraulic oil and effectively reducing the difficulty of subsequent filtering treatment.

[0017] In the specific implementation process, as a preferred setting, the above-mentioned combined filter assembly includes a first nylon filter 14 and a second nylon filter 15 which are sequentially arranged in the second filter chamber 6, and a silicon carbide ceramic tubular membrane 16 is arranged between the first nylon filter 14 and the second nylon filter 15. It should be pointed out that the nylon filter is mainly made of PP fiber (polypropylene fiber) woven into a whole. This material has the characteristics of acid and alkali resistance and good corrosion resistance, and has low resistance, can be repeatedly cleaned, and is extremely economical; the silicon carbide ceramic tubular membrane 16 is fired by a recrystallization process, has excellent filtering performance and flux, and has high strength, high hardness, high wear resistance and excellent chemical stability: the silicon carbide ceramic tubular membrane 16 can operate stably for a long time in extreme environments, and has excellent resistance to various chemical corrosion, which can preferably improve the filtering interception effect.

[0018] In the specific implementation process, as a preferred setting, the above-mentioned multi-stage filler adsorption layer includes an acid adsorbent filler layer 17, a nano-silicon dioxide particle filler layer 18 and an activated carbon particle filler layer 19 arranged in sequence from bottom to top in the vertical direction; the nano-silicon dioxide particle filler layer 18 can effectively adsorb impurities and tiny particles suspended in the hydraulic oil, and play a role in filtering and cleaning the hydraulic oil; the setting of the acid adsorbent filler layer 17 is because there is often a small amount of acidic substance in the hydraulic oil, which can easily cause corrosion and oxidation of metal parts. The use of acidic adsorbents can adsorb these harmful substances and protect the normal operation of the hydraulic system; the activated carbon particle filler layer 19 has a strong adsorption capacity and can effectively adsorb and remove impurities such as ozone, free acid, and water in the hydraulic oil, so that the secondary reused hydraulic oil can effectively ensure the stability and safety of the hydraulic system.
