Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and in particular to a device for detecting the concentration of oil particles in a filter. Background Art

[0002] A filter is a mechanical device used to separate solid particles from liquid or gas. Through a specific filter medium, solid particles are trapped on the medium, while the liquid or gas flows out through the medium, thereby achieving the purpose of purification or separation. Filters are widely used in many fields such as chemical industry, pharmaceuticals, food processing, water treatment, oil and gas, environmental engineering, etc. for the purification, separation and recovery of liquids or gases.

[0003] Oil particle detection can directly reflect the degree of oil wear. Through the analysis of particle size, it is possible to predict the wear problems of mechanical equipment, so as to carry out maintenance in advance and avoid failures. By regularly testing the particle size of oil products, it is possible to reasonably formulate the oil replacement cycle, avoid the performance degradation caused by oil aging, and thus extend the service life of the equipment.

[0004] By detecting the oil particle concentration, extracting data as the basis for the equipment to automatically operate the filter pump, analyzing the test process, comparing the tests before and after adding the energy-saving module to the filter pump, and comparing the energy saving of the start-stop pump and the frequency conversion pump.

[0005] In the existing filter oil particle concentration detection device, as the use time increases, the particles and oil droplets captured by the filter layer have high viscosity and are difficult to remove when attached to the surface of the filter layer. Too many particles accumulate on the surface impurities of the filter layer, which increases the pressure drop of the filter layer and gradually increases the resistance, making it impossible to screen the particles in the oil in time. In addition, the oil contains a variety of different impurities, and conventional filtering methods cannot be used to screen and detect the metal particles therein, thereby failing to accurately detect the concentration of the metal particles. The attachment to the filter surface increases the power consumption of the detection process, thereby affecting the accuracy of the judgment of the oil quality. In addition, most of the existing equipment is a sealed structure, and a large amount of impurities will accumulate inside after long-term use. Therefore, a device for detecting the concentration of oil particles in a filter is proposed. Summary of the invention

[0019] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0020] like Figure 1-Figure 8 The device for detecting the concentration of oil particles in a filter shown in the figure comprises a mounting frame 3, a lifting frame 2 is provided at the rear end of the mounting frame 3, a lifting mechanism is provided at the front end of the lifting frame 2, an upper cover 102 is provided at the lower end of the lifting mechanism, a filter cartridge 1 is provided at the lower end of the upper cover 102, an insert iron removal mechanism is provided on the outer surface of the filter cartridge 1, a rotating motor 101 is provided at the upper end of the upper cover 102, the rotating motor 101 passes through the upper cover 102 and is provided with a scraping mechanism, a clamping seat 108 is provided at the lower end of the inner wall of the filter cartridge 1, a material guide trough 10 is provided at the lower end of the filter cartridge 1, and a discharge mechanism is provided at the lower end of the material guide trough 10.

[0021] like Figure 1-Figure 2 As shown, the lifting mechanism includes a lifting motor 4 fixedly installed at the lower end of the front surface of the lifting frame 2, a guide rail 6 is provided at the output end of the lifting motor 4, a symmetrical lifting track 9 is provided on the front surface of the lifting frame 2, and a lifting seat 5 is slidably installed on the outer side of the lifting track 9. When it is necessary to perform regular inspection or cleaning on the inside of the filter cartridge 1, the lifting seat 5 is controlled by the lifting motor 4 to drive the upper cover 102 to be lifted and lowered, so that the operator can handle the inside conveniently.

[0022] like Figure 3-Figure 4 As shown, a card slot 12 is provided at the upper end of the filter cartridge 1, and an annular lock 7 is rotatably installed on the outer side of the upper cover 102 and the card slot 12. Bosses 11 are provided near the outer surface of the annular lock 7, and a lock buckle 8 is rotatably installed on one side of the boss 11. In order to prevent external pollutants from entering the filter cartridge 1 and interfering with the detection accuracy during the detection process, the rotatably installed annular lock 7 is used to fix and seal the upper cover 102 and the filter cartridge 1, and the bosses 11 on both sides are locked by the lock buckle 8.

[0023] The inner wall of the filter cartridge 1 is provided with four slide rails 106 arranged at equal angles, a holder 108 is fixedly installed at the lower end of the inner wall of the filter cartridge 1, a filter screen 107 is slidably installed between the slide rails 106 and the holder 108, and when the filter screen 107 needs to be inspected and replaced, the operator slides the filter screen 107 along the slide rails 106 to the upper end of the holder 108, and the holder 108 forms a seal with the lower end of the inner wall of the filter cartridge 1, so that the oil can only pass through the filter screen 107, thereby increasing the accuracy of concentration detection.

[0024] like Figure 5 As shown, the plug-in iron removal mechanism includes an insertion slot 15 fixedly installed through the inside of the filter cartridge 1, and a number of round supports 16 are equidistantly arranged inside each insertion slot 15, and a permanent magnetic column 14 is arranged inside the round support 16. This equipment is mainly used for the detection of metal particle concentration in oil. A permanent magnetic column 14 that can be manually inserted according to the detection situation is used. The metal particles inside the filter cartridge 1 can be adsorbed through the movable installation of the insertion slot 15. When the oil screening is completed, the permanent magnetic column 14 is pulled out. At this time, the metal particles adsorbed on the outer surface of the insertion slot 15 lose their magnetism and fall into the material guide trough 10 for centralized discharge.

[0025] like Figure 6 As shown, the discharging mechanism includes a discharging motor 301 fixedly installed on one side of the slag discharging port 105, and an annular valve 303 is provided on the side of the slag discharging port 105 close to the discharging motor 301. A clamping plate 302 is provided at the output end of the discharging motor 301 through the annular valve 303. After the oil screening is completed after scraping and collecting by the permanent magnetic column 14, the metal particles in the oil are concentratedly collected in the guide trough 10. The discharging motor 301 is controlled to drive the clamping plate 302 to rotate, and the clamping plate 302 rotates to open the internal channel of the annular valve 303 to discharge the metal particles, so that the operator can obtain the oil particle concentration detection data.

[0026] like Figure 7-Figure 8 As shown, the scraping mechanism includes a rotating motor 101 fixedly mounted on the upper surface of the upper cover 102, and a roller 201 is provided at the rotating end of the rotating motor 101 through the upper cover 102, and two round tables 208 are provided on the outer surface of the roller 201, which are used to fix the pillar 202 for stable operation, and the rotation of the roller 201 is controlled by the rotating motor 101.

[0027] The outer surface of each truncated cone 208 is provided with three pillars 202 arranged at equal angles, and each outer surface is provided with a clamping claw 203. A rotating ring 205 is installed between every two clamping claws 203 arranged up and down. A spring 204 is sleeved on the outer surface of the clamping claw 203. A scraper 206 is provided between the two clamping claws 203. A circular ring 207 is provided at the lower end of the roller 201. A support seat 13 is provided on the inner side of the holder 108. The support seat 13 is fixedly installed at the lower end of the circular ring 207. The support seat 13 provides support for the roller 201, so that it can rotate stably. Since the rotating ring 205 is rotatably installed between the two clamping claws 203, the scraper 206 installed by the support arm 210 can rotate independently, and a plurality of equidistantly arranged scraping grooves 209 are opened on the outer surface of each scraper 206. When the rotating motor 101 rotates, the three scrapers 206 rotate in contact with the inner surface of the filter screen 107, thereby scraping off the metal particles not adsorbed by the permanent magnetic column 14, thereby improving the accuracy of detection.

[0028] Two groups of supporting arms 210 arranged at equal angles are provided between the outer surface of the rotating ring 205 and the inner surface of the scraper cylinder 206 , and a plurality of scraper grooves 209 arranged at equal distances are provided on the surface of the scraper cylinder 206 .

[0029] Working principle: The oil that needs to be tested for particle concentration is input into the filter cartridge 1 through the feed port 103. The data before and after adding the energy-saving module are judged by the test results of the oil particle concentration, as well as the comparison results of the energy saving of the start-stop pump and the variable frequency pump.

[0030] Before starting the test, the operator places the filter 107 inside the filter cartridge 1 according to the oil usage. The inner wall of the filter cartridge 1 is provided with four slide rails 106 arranged at equal angles. The filter 107 is installed inside the filter cartridge 1 along the slide rails 106. A holder 108 is provided at the lower end of the inner wall of the filter cartridge 1 as a limit seal. The holder 108 cooperates with the filter 107 to form a closed space for the oil inside the filter cartridge 1. The oil can only be discharged through the sieve holes on the surface of the filter 107, and the particulate matter in the oil is collected in the guide trough 10.

[0031] Two insertion grooves 15 are provided at the upper end of the filter cartridge 1, and an insertion groove 15 is provided at the lower end located in the material guide groove 10, which respectively adsorb metal particles on the oil that initially enters the filter cartridge 1 and the oil that has been screened. After the oil is screened, the staff manually inserts the permanent magnetic column 14 according to the screening and filtration progress. When the permanent magnetic column 14 is pulled out of the insertion groove 15, the metal particles adsorbed on the outer surface of the insertion groove 15 located inside the filter cartridge 1 fall into the material guide groove 10, thereby facilitating centralized discharge.

[0032] After the oil enters the filter cartridge 1, the operator starts the rotating motor 101 fixedly installed on the upper end of the upper cover 102. The output end of the rotating motor 101 passes through the upper cover 102. A roller 201 is provided inside the filter cartridge 1. The roller 201 is located inside the filter cartridge 1 and has two round tables 208. The outer surface of each round table 208 is provided with three pillars 202 arranged at equal angles, and the outer surface of each pillar 202 is provided with a clamping claw 203. A rotating ring 205 is rotatably installed between each two upper and lower clamping claws 203. The outer surface of the clamping claw 203 is provided with a rotating ring 205. A spring 204 is provided between the rotating ring 205 and the support 202. The elasticity of the spring 204 enables the scraper 206 to be in close contact with the inner surface of the filter 107. The particles attached to the inner surface of the filter 107 are promptly scraped off by the rotating motor 101. The outer surface of each scraper 206 is provided with a plurality of equidistantly arranged scraping grooves 209. When the rotating motor 101 is driven, the scraping efficiency of the sediment on the inner surface of the filter 107 is effectively increased, and the scraped particles settle into the guide groove 10 at the lower end of the filter cylinder 1.

[0033] The oil screened by the filter 107 is discharged through the drain port 104, and the settled particles are discharged by the discharge mechanism arranged at the slag discharge port 105. The metal particles accumulate between the guide trough 10 and the slag discharge port 105. The operator controls the discharge motor 301 according to the filtering situation, and the discharge motor 301 rotates the clamping plate 302. The clamping plate 302 rotates inside the annular valve 303 and the particles are discharged.

[0034] A circular ring 207 is disposed at the lower end of the rotating roller 201 , and a supporting seat 13 is disposed inside the holder 108 . The supporting seat 13 is fixedly mounted at the lower end of the circular ring 207 . The supporting seat 13 provides support for the circular ring 207 , so that the rotating roller 201 can run stably.

[0035] By analyzing the test results of the discharged dirty liquid, extracting data as the basis for automatically operating the filter pump, analyzing the test process and rationality, comparing the filter pump before and after adding the energy-saving module, and setting up a comparison of energy saving between the start and stop pump and the variable frequency pump, and setting up automatic removal of particles, the test is made more accurate and the error of multiple tests can be further reduced, thereby concluding the impact of oil particles on equipment operation.
