Description

Technical Field

[0001] This utility model relates to the field of continuous casting machine technology, and in particular to a backflow filter for continuous casting machines. Background Technology

[0002] A continuous casting machine is a device used to continuously cast high-temperature molten steel into billets with specific cross-sectional shapes and dimensions. During the steel processing, high-temperature molten steel is continuously poured into one or more water-cooled copper crystallizers. The molten steel gradually solidifies into a billet shell along the periphery of the crystallizer. Once the molten steel level rises to a certain height and the billet shell solidifies to a certain thickness, a straightening machine pulls the billet out, and it undergoes secondary cooling by water spray to completely solidify. During the water spray cooling process, a counter-current backwash filter is typically used to filter the cooling water. The backwash filter is a precision device that uses a filter screen to directly intercept impurities in the water, removing suspended solids and particulate matter, reducing turbidity, and purifying the water quality to protect other equipment in the system. Water enters the self-cleaning filter body through the inlet. Due to its intelligent design (PLC, PAC), the system can automatically identify the degree of impurity deposition and send a signal to the drain valve for automatic drainage.

[0003] However, existing backwash filters typically use water rinsing to achieve the purpose of rinsing the filter screen, but the cleaning quality is low and it cannot effectively clean the inside of the filter screen, affecting its service life, which needs to be improved.

[0004] Therefore, this application proposes a backflow backwash filter for continuous casting machines to solve the problems in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a backflow filter for continuous casting machines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A backflow backwash filter for a continuous casting machine, comprising a filter tank connected to the continuous casting machine's drain pipe, a cleaning mechanism, and a control module;

[0008] A filter element is fixedly installed inside the filter canister. A cleaning mechanism is provided inside the filter canister and is connected to the filter element. A control module is installed on the filter canister and is connected to the control module.

[0009] The cleaning mechanism includes a circular plate, a scraper, a reinforcing ring, and a motor. The circular plate is rotatably connected inside the filter tank, and the scraper is fixedly connected to the top of the circular plate. The two ends of the scraper are respectively in contact with the outer side of the filter element and the inner side of the filter tank. The top of the scraper is fixedly connected to the reinforcing ring, which is rotatably sleeved on the filter element. Through the coordinated design of the filter tank, filter element, circular plate, scraper, reinforcing ring, motor, and control module, the impurities attached to the outer side of the filter element and the inner side of the filter tank can be scraped and cleaned, which not only shortens the cleaning time but also improves the cleaning effect.

[0010] Specifically, an electric motor is fixedly installed on the top of the filter tank. The output end of the electric motor passes through the filter tank and is fixedly connected to the circular plate. Driven by the electric motor, the circular plate rotates inside the filter tank. At the same time, the circular plate drives the scraper to rotate synchronously. Meanwhile, the two ends of the scraper act on the outer side of the filter element and the inner side of the filter tank, respectively, thereby achieving the effect of automatically scraping away impurities.

[0011] Specifically, a limiting groove is formed on the top of the circular plate, and one end of the filter element is set in the limiting groove. The motor is connected to the control module. The limiting groove can limit the filter element to achieve a reinforcement effect and improve stability.

[0012] Specifically, a three-way pipe is sealed to one side of the filter tank, and a water inlet pipe is sealed to one side of the three-way pipe. A solenoid valve is installed on the water inlet pipe, which is connected to the control module. The water inlet pipe is connected to the drain pipe on the continuous casting machine via a flange. Then, the solenoid valves are opened, allowing wastewater to enter the filter tank through the water inlet pipe. Simultaneously, the filter element filters impurities in the wastewater, and the filtered wastewater is discharged through the drain pipe, thus achieving the effect of filtering wastewater.

[0013] Specifically, one end of the three-way pipe is sealed and connected to a drain pipe, and a solenoid valve is installed on the drain pipe. The solenoid valve is connected to the control module. The top of the filter tank is sealed and connected to the three-way pipe, which corresponds to the filter element. One end of the three-way pipe is sealed and connected to the drain pipe, and a solenoid valve is installed on the drain pipe. The other end of the three-way pipe is sealed and connected to a water inlet pipe, and a solenoid valve is installed on the water inlet pipe. Both the solenoid valve and the solenoid valve are connected to the control module. When the filter element needs to be cleaned, the solenoid valves are closed and the solenoid valves are opened. The solenoid valves are opened and the motor is opened. At this time, the cleaning solution is delivered to the filter element through the water inlet pipe by an external liquid pump and discharged through the filter holes on the filter element, thereby achieving the effect of backwashing the filter element. Then, the wastewater from the cleaning is discharged into the impurity collection box through the drain pipe.

[0014] Specifically, a sealed bearing is fixedly fitted at the output end of the motor, and the outer wall of the sealed bearing is fixedly connected to the filter tank to improve the sealing performance, which not only prevents leakage but also ensures the normal operation of the motor output end.

[0015] Specifically, the circular plate and the reinforcing ring are both adapted to the filter canister to prevent impurities from entering between the circular plate, the reinforcing ring, and the filter canister.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model discloses a counter-current backflushing filter for continuous casting machines. Through the coordinated design of the filter tank, filter element, circular plate, scraper, reinforcing ring, motor, and control module, it can effectively scrape and clean impurities attached to the outside of the filter element and the inside of the filter tank. This not only shortens the cleaning time but also improves the cleaning effect, making it more practical and worthy of widespread promotion. Attached Figure Description

The top of the scraper 5 is fixedly connected to the reinforcing ring 4, which is rotatably sleeved on the filter element 2. Through the coordinated design of the filter tank 1, filter element 2, circular plate 3, scraper 5, reinforcing ring 4, motor 6, and control module 7, the impurities attached to the outer side of the filter element 2 and the inner side of the filter tank 1 can be scraped and cleaned, which not only shortens the cleaning time but also improves the cleaning effect.

[0028] In this embodiment, a motor 6 is fixedly installed on the top of the filter tank 1. The output end of the motor 6 passes through the filter tank 1 and is fixedly connected to the circular plate 3. Driven by the motor 6, the circular plate 3 rotates inside the filter tank 1. At the same time, the circular plate 3 drives the scraper 5 to rotate synchronously. Meanwhile, the two ends of the scraper 5 act on the outer side of the filter element 2 and the inner side of the filter tank 1, respectively, thereby achieving the effect of automatically scraping away impurities.

[0029] In this embodiment, a limiting groove 18 is provided on the top of the circular plate 3, and one end of the filter element 2 is set in the limiting groove 18. The motor 6 is connected to the control module 7. The limiting groove 18 can limit the filter element 2 to achieve the effect of reinforcement and improve stability.

[0030] In this embodiment, a three-way pipe 8 is sealed to one side of the filter tank 1, and a water inlet pipe 9 is sealed to one side of the three-way pipe 8. A solenoid valve 10 is installed on the water inlet pipe 9, and the solenoid valve 10 is connected to the control module 7. The water inlet pipe 9 is connected to the sewage pipe on the continuous casting machine through a flange. Then, the solenoid valve 10 and the solenoid valve 15 are opened, so that the sewage enters the filter tank 1 through the water inlet pipe 9. At the same time, the impurities in the sewage are filtered by the filter element 2, and the filtered sewage is discharged through the drain pipe 14, thereby achieving the effect of filtering sewage.

[0031] In this embodiment, one end of the three-way pipe 8 is sealed and connected to a drain pipe 11. A solenoid valve 12 is installed on the drain pipe 11 and is connected to the control module 7. The top of the filter tank 1 is sealed and connected to a three-way pipe 13, which corresponds to the filter element 2. One end of the three-way pipe 13 is sealed and connected to a drain pipe 14, on which a solenoid valve 15 is installed. The other end of the three-way pipe 13 is sealed and connected to a water inlet pipe 16, on which a solenoid valve 17 is installed. Both solenoid valve 4 17 and solenoid valve 3 15 are connected to control module 7. When the filter element 2 needs to be cleaned, solenoid valve 1 10 and solenoid valve 3 15 are closed, and solenoid valve 2 12, solenoid valve 4 17 and motor 6 are opened. At this time, the cleaning liquid is delivered to the filter element 2 through the water inlet pipe 2 16 by the external liquid pump, and discharged through the filter holes on the filter element 2, thereby achieving the effect of backwashing the filter element 2. Then, the cleaned sewage is discharged into the impurity collection box through the drain pipe 1 11.

[0032] In this embodiment, a sealed bearing is fixedly fitted at the output end of the motor 6.

Two sealing rings are fixedly installed in the reinforcing ring 4 and the limiting groove 18. The two sealing rings are both sleeved on the filter element 2 to further improve the sealing performance.

[0034] Working principle: When in use, the inlet pipe 9 is connected to the drain pipe on the continuous casting machine through the flange. Then, the solenoid valve 10 and solenoid valve 3 15 are opened, so that the sewage enters the filter tank 1 through the inlet pipe 9. At the same time, the impurities in the sewage are filtered by the filter element 2, and the filtered sewage is discharged through the drain pipe 2 14, thereby achieving the effect of filtering sewage.

[0035] When the filter element 2 needs to be cleaned, the solenoid valve 10 and solenoid valve 35 are closed, and the solenoid valve 2 12, solenoid valve 4 17 and motor 6 are opened. At this time, the cleaning liquid is delivered to the filter element 2 through the water inlet pipe 2 16 by the external liquid pump, and discharged through the filter holes on the filter element 2, thereby achieving the effect of backwashing the filter element 2. Then, the wastewater from the cleaning is discharged into the impurity collection box through the drain pipe 11.

[0036] Meanwhile, the circular plate 3 is driven by the motor 6 to rotate inside the filter tank 1. At the same time, the circular plate 3 drives the scraper 5 to rotate synchronously. Simultaneously, the two ends of the scraper 5 act on the outer side of the filter element 2 and the inner side of the filter tank 1, respectively, thereby achieving the effect of scraping and cleaning the impurities attached to the outer side of the filter element 2 and the inner side of the filter tank 1. This not only shortens the cleaning time but also improves the cleaning effect.

[0037] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, not only can the filter element 2 be backwashed in a countercurrent manner, but also impurities attached to the outside of the filter element 2 and the inside of the filter tank 1 can be scraped and cleaned. This not only shortens the cleaning time but also improves the cleaning effect. Moreover, the structure is simple and the practicality is higher.
