Description

Technical Field

[0001] This invention relates to the field of metallurgical filtration technology, and in particular to an oil filtration device for steel plate rolling. Background Technology

[0002] Rolling sludge produced during the steel plate rolling process usually contains metal scraps, colloids and other particulate impurities. After the rolling sludge enters the filtration equipment, the filter layer intercepts the impurities, which tend to adhere to the surface of the filter layer and gradually form a deposit layer.

[0003] If the accumulated impurities on the surface of the filter layer are not removed in time, the flow resistance of the rolling oil through the filter layer will increase, and the initial filtration efficiency will be affected. Manual disassembly and cleaning will also affect the continuous operation of the filtration equipment. When there are assembly gaps in the impurity discharge part of the filtration equipment, the rolling oil is also prone to leakage.

[0004] Therefore, this invention proposes a steel plate rolling oil filtration device to solve the problems of impurities easily accumulating on the surface of the filter layer and rolling oil leakage easily occurring during the cleaning and discharge process. Summary of the Invention

[0005] In view of the problems in the existing steel plate rolling oil filtration equipment, such as the continuous accumulation of impurities on the surface of the filter layer, untimely cleaning and discharge of impurities, and easy leakage of rolling oil in the assembly gap of the waste discharge part, the present invention aims to provide a steel plate rolling oil filtration equipment with an improved structure that can effectively solve the above problems.

[0006] This invention provides a steel plate rolling oil filtration device, including a primary fine filter. A filter layer is fixedly connected to the inner wall of the primary fine filter. A slag scraping and waste discharge mechanism is provided on the inner wall of the primary fine filter. The slag scraping and waste discharge mechanism includes a drive scraper. A linkage scraper is slidably assembled inside the drive scraper. A spring is fixed to one side of the linkage scraper. A conforming guide plate is fixed to the outside of the linkage scraper. A waste discharge chamber is fixed to the inner wall of the primary fine filter. A sealing cover is slidably mounted inside the waste discharge chamber. The outer wall of the sealing cover slides in contact with the outer wall of the conforming guide plate. The conforming guide plate drives the sealing cover to slide and open the waste discharge chamber.

[0007] As a further description of the above technical solution The fitting guide plate slides against the inner wall of the primary fine filter, and the spring applies a pushing force toward the inner wall of the primary fine filter to the linkage scraper.

[0008] As a further description of the above technical solution The inner wall of the primary fine filter is equipped with a sealing assembly, which includes a sealing ring. The outer wall of the sealing ring is fixed to the inner wall of the primary fine filter, and the inner wall of the sealing ring slides against the outer wall of the drive scraper.

[0009] As a further description of the above technical solution The sealing assembly also includes a sealing strip, which is fixed to the inner wall of the waste discharge chamber and slides against the outer wall of the sealing cover.

[0010] As a further description of the above technical solution The filtration equipment also includes a staged filtration mechanism, which includes a condenser connected to the inner wall of the first-stage fine filter. The inner wall of the condenser is connected to an electric field adsorption tank, and an electromagnetic coil is fixed on the outer surface of the electric field adsorption tank.

[0011] As a further description of the above technical solution The inner wall of the electric field adsorption tank is connected to a vacuum dewatering device, and the inner wall of the vacuum dewatering device is connected to a two-stage fine filter.

[0012] As a further description of the above technical solution The vacuum dehydrator is fixedly connected to a support assembly at its bottom. The support assembly includes a crossbeam, and a support column is mounted at the bottom of the crossbeam.

[0013] As a further description of the above technical solution The filtration equipment also includes a drive and delivery assembly, which includes an oil pump disposed on the outer wall of the primary fine filter and has a return pipe connected inside.

[0014] The present invention has the following beneficial effects: 1. This invention solves the problem of impurities continuously adhering to the outside of the filter layer and forming a deposit layer during the filtration process of rolling oil, which leads to a decrease in the oil flow capacity of the filter layer. This invention achieves timely removal of impurities on the surface of the filter layer and maintenance of initial filtration stability.

[0015] 2. This invention opens the waste discharge chamber by squeezing the sealing cover plate with the guide plate to slide, and uses the sealing ring and sealing strip to seal the assembly gap at the drive scraper and the sealing cover plate. This solves the problems of inconvenient discharge of filtered impurities and easy leakage of rolling oil from the assembly gap, and achieves centralized discharge of impurities and closed operation of filtration.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example:

[0019] Please refer to Figures 1 to 5 The steel plate rolling oil filtration equipment uses a primary fine filter 1 to perform preliminary filtration of the rolling sludge oil. The inner wall of the primary fine filter 1 is fixedly connected to the filter layer 201. The filter layer 201 intercepts impurities in the sludge oil. The inner wall of the primary fine filter 1 is equipped with a sludge scraping and waste discharge mechanism 2. After the impurities on the outside of the filter layer 201 form an accumulation layer, the sludge scraping and waste discharge mechanism 2 scrapes off the impurities and discharges them.

[0020] Please refer to Figures 3 to 5The slag removal and waste discharge mechanism 2 includes a drive scraper 202 disposed on the inner wall of the primary fine filter 1. A linkage scraper 203 is slidably mounted inside the drive scraper 202. One side of the linkage scraper 203 is fixedly connected to a spring 204, and the outer side of the linkage scraper 203 is fixedly connected to a guide plate 205. The bottom of the drive scraper 202 and the bottom of the linkage scraper 203 are in sliding contact with the top of the filter layer 201. The spring 204 continuously applies a pushing force toward the inner wall of the primary fine filter 1 to the linkage scraper 203, so that the guide plate 205 slides and adheres to the inner wall of the primary fine filter 1. When the drive scraper 202 is manually pulled, the drive scraper 202 drives the linkage scraper 203 and the guide plate 205 to move along the top of the filter layer 201 to scrape off the accumulated impurities attached to the outer wall of the filter layer 201.

[0021] Please refer to Figure 3 and Figure 4 The inner wall of the primary fine filter 1 is fixedly connected to the waste discharge chamber 206. The interior of the waste discharge chamber 206 is slidably connected to the sealing cover plate 207. The outer wall of the sealing cover plate 207 slides in contact with the outer wall of the fitting guide plate 205. When the fitting guide plate 205 moves with the drive scraper 202, it squeezes the sealing cover plate 207 and slides it upward. The sealing cover plate 207 opens the waste discharge chamber 206, so that the scraped impurities are collected in the waste discharge chamber 206 and discharged outward. The inner wall of the primary fine filter 1 is equipped with a sealing cover. Component 208, the sealing component 208 includes a sealing ring 2081, the outer wall of the sealing ring 2081 is fixedly connected to the inner wall of the primary fine filter 1, the inner wall of the sealing ring 2081 is slidably attached to the outer wall of the drive scraper 202, the sealing component 208 also includes a sealing strip 2082, the sealing strip 2082 is fixedly connected to the inner wall of the waste discharge chamber 206, the sealing strip 2082 is slidably attached to the outer wall of the sealing cover plate 207, the sealing ring 2081 and the sealing strip 2082 respectively seal the corresponding assembly gaps.

[0022] Please refer to Figure 1 and Figure 2The steel plate rolling oil filtration equipment is equipped with a graded filtration mechanism 3. The graded filtration mechanism 3 includes a condenser 301 connected to the inner wall of the primary fine filter 1. The inner wall of the condenser 301 is connected to an electric field adsorption tank 302. The outer surface of the electric field adsorption tank 302 is fixedly connected to an electromagnetic coil 303. The inner wall of the electric field adsorption tank 302 is connected to a vacuum dehydrator 304. The inner wall of the vacuum dehydrator 304 is connected to a secondary fine filter 305. The bottom of the vacuum dehydrator 304 is fixedly connected to a support assembly 306. The support assembly 306 includes a crossbeam 3061. The bottom of the 61 is equipped with a support column 3062. The crossbeam 3061 and the support column 3062 support the vacuum dehydrator 304. The steel plate rolling oil filtration equipment is also equipped with a drive conveying assembly 4. The drive conveying assembly 4 includes an oil pump 401 installed on the outer wall of the primary fine filter 1. The oil pump 401 is connected to the return pipe 402. The oil pump 401 provides conveying power for the flow of oil between the primary fine filter 1, condenser 301, electric field adsorption tank 302, vacuum dehydrator 304 and secondary fine filter 305. The return pipe 402 allows excess oil to be returned and circulated.

[0023] Working principle: When using the slag scraping and waste discharge mechanism 2, the sludge oil generated by the rolling mill is introduced into the first-stage fine filter 1 for preliminary purification. Since the outer wall of the filter layer 201 is fixedly connected to the inner surface of the first-stage fine filter 1, when the sludge oil flows through the filter layer 201, the impurities inside the oil are intercepted on the outside of the filter layer 201, and the clean oil passes through the filter layer 201 and is transported inward. The impurities continue to adhere to the outer wall of the filter layer 201 to form a deposit layer. Since the drive scraper 202 is set on the inner wall of the first-stage fine filter 1, and the linkage scraper 203 is slidably assembled on the drive scraper 202, the sludge scraper 202 is fixedly connected to the filter layer 201. Inside the drive scraper 202, a spring 204 is fixed to one side of the linkage scraper 203. Therefore, the spring 204 continuously applies an outward pushing force to the linkage scraper 203, thereby ensuring that the outer side of the linkage scraper 203, the contact guide plate 205, always slides tightly against the inner wall of the primary fine filter 1. At the same time, since the bottoms of the drive scraper 202 and the linkage scraper 203 are in sliding contact with the top of the filter layer 201, when the drive scraper 202 is manually pulled outward, the linkage scraper 203 and the contact guide plate 205 will be simultaneously driven along the top of the filter layer 201. The system uniformly scrapes away accumulated impurities, which then collect at the waste discharge chamber 206. Since the waste discharge chamber 206 is fixed to the inner wall of the primary fine filter 1, the sealing cover 207 slides inside the waste discharge chamber 206, and the outer wall of the sealing cover 207 slides in contact with the outer wall of the guide plate 205. As the drive scraper 202 rotates, the guide plate 205 can squeeze the sealing cover 207 to slide upwards intermittently, thus periodically opening the waste discharge chamber 206 to allow impurities to be discharged. Because the sealing assembly 208 is installed... The sealing ring 2081 is fixed to the inner wall of the first-stage fine filter 1, and the inner wall slides against the outer wall of the drive scraper 202. The sealing strip 2082 is fixed to the inner wall of the waste discharge chamber 206 and slides against the outer wall of the sealing cover plate 207. Therefore, the sealing ring 2081 seals the gap between the drive scraper 202 and the filter body, and the sealing strip 2082 seals the gap between the sealing cover plate 207 and the waste discharge chamber 206, thereby preventing rolling oil from leaking from the assembly gap throughout the process and ensuring the closed and stable operation of the filtration operation. When using the equipment, the rolling sludge is first fed into the primary fine filter 1 for preliminary filtration. Since the inner wall of the primary fine filter 1 is connected to the condenser 301 within the staged filtration mechanism 3, the oil after preliminary filtration flows into the condenser 301, where low-temperature cooling reduces the activity of light impurities and water vapor. Because the inner wall of the condenser 301 is connected to the electric field adsorption tank 302, the oil continuously flows into the electric field adsorption tank 302. The electromagnetic coil 303 is fixed to the outer surface of the electric field adsorption tank 302. When energized, the electromagnetic coil 303 forms a stable electric field, causing fine colloidal particles and metal microparticles in the oil to be adsorbed onto the inner wall of the tank under the action of the electric field, thus completing the separation of ultrafine impurities. Since the inner wall of the electric field adsorption tank 302 is connected to the vacuum dehydrator 304, the oil after adsorption treatment flows into the vacuum dehydrator 304. 04. The vacuum environment can remove the mixed water inside the oil. The bottom of the vacuum dehydrator 304 is fixedly connected to the crossbeam 3061. The bottom of the crossbeam 3061 is equipped with a support column 3062 to form a support assembly 306. Therefore, the support assembly 306 stably supports the vacuum dehydrator 304 and avoids deformation and leakage at the pipeline connection. Since the inner wall of the vacuum dehydrator 304 is connected to the secondary fine filter 305, the dehydrated oil enters the secondary fine filter 305 for deep purification. At the same time, the outer wall of the primary fine filter 1 is equipped with a drive conveying assembly 4. The oil pump 401 is located on the outer wall of the primary fine filter 1. The oil pump 401 is connected to the return pipe 402. Therefore, the oil pump 401 continuously provides conveying power for the entire pipeline. Excess oil is returned and circulated through the return pipe 402, thereby ensuring the continuous and stable flow of oil in the graded filtration mechanism 3.
