Description

Technical Field

[0001] This utility model relates to the field of ceramic filter technology, specifically a ceramic filter with a swing scraper. Background Technology

[0002] During operation, ceramic filters tend to accumulate minerals on both sides of the filter plates. When the minerals accumulate to a certain amount, they compress the filter plates and extend outwards. Current technology typically relies on manual cleaning of mineral residue between the oscillating scrapers. However, if unattended, the accumulation of minerals to a critical level can cause a sudden increase in the operating resistance of the filter plates, leading to their breakage. This problem not only affects production efficiency but also increases equipment maintenance costs. Therefore, an automated solution is urgently needed to monitor and clean mineral accumulation in real time, preventing filter plate damage. Utility Model Content

[0003] The purpose of this invention is to provide a ceramic filter with a swing scraper, which solves the problem of filter plate clogging and damage caused by mineral accumulation through laser detection and automatic control technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A ceramic filter with a swing scraper includes a ceramic filter body, which includes a ceramic filter plate and a ceramic filter scraper. The swing scraper support is located on the side of the ceramic filter close to the scraper. A rotating shaft is located at the top of the support, and the swing scraper is connected to the shaft. One end of the swing scraper is fixedly connected to the shaft, while the other end is free. The blade edge of the swing scraper is parallel to the side of the filter plate and extends towards the rear of the filter plate. The swing scraper has a cutting edge that is close to but does not contact the filter plate. A swing motor is connected to the side of the rotating shaft.

[0006] Furthermore, the swing scraper bracket is provided with a pair of laser beam switches on the side near the filter plate of the ceramic filter. The laser beam switches are located in front of the filter plate of the ceramic filter, and are respectively located on the left and right sides of the filter plate of the ceramic filter. The laser beam switches are electrically connected to the swing motor.

[0007] Furthermore, the oscillating scraper is provided with an upper blade and a lower blade. The upper blade is located at the upper edge of the oscillating scraper, and the lower blade is located at the lower edge of the oscillating scraper. The cutting edges of the upper blade and the lower blade are arranged opposite to each other. By providing two blades, the oscillating motor can repeatedly scrape off the mineral deposits on the filter plate of the ceramic filter machine when it is running.

[0008] Furthermore, the angle between the cutting edge of the upper blade and the end face of the oscillating scraper is 45°-60°; by limiting the angle between the cutting edge of the upper blade and the end face of the oscillating scraper, the resistance to cutting into the mineral deposit is optimized, making the blade tip cut into the mineral deposit more smoothly.

[0009] Furthermore, the top of the swing scraper support is higher than the highest point of the ceramic filter scraper; by raising the swing scraper support, mechanical interference with the existing equipment is avoided.

[0010] Furthermore, the swing scraper bracket is equipped with a switch bracket, and the laser beam switch is fixed on the switch bracket; by setting the switch bracket, the position of the laser beam switch can be adjusted according to the production situation to prevent the filter plate from being damaged by mineral accumulation.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Real-time monitoring of mineral accumulation via laser beam switches enables automated control and reduces manual intervention.

[0013] 2. The double-blade design improves cleaning efficiency and prevents secondary accumulation of minerals.

[0014] 3. The height of the support frame is optimized to avoid conflicts with existing equipment and ensure stable operation. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0019] A ceramic filter 1 with a swing scraper 8 includes a ceramic filter 1 body, which includes a ceramic filter plate 2 and a ceramic filter scraper 3. The ceramic filter 1 body also includes a swing scraper support 4, which is located on the side of the ceramic filter 1 near the ceramic filter scraper 3. The top of the swing scraper support 4 is provided with a rotating shaft 5, and the swing scraper 8 is connected to the rotating shaft 5. One end of the swing scraper 8 is fixedly connected to the rotating shaft 5, and the other end forms a free end. The cutting edge of the swing scraper 8 is parallel to the side of the ceramic filter plate 2, and the swing scraper 8 extends toward the rear side of the ceramic filter plate 2.

[0020] The oscillating scraper 8 has an upper blade 801 and a lower blade 802. The upper blade 801 is located at the upper edge of the oscillating scraper 8, and the lower blade 802 is located at the lower edge of the oscillating scraper 8. The cutting edges of the upper blade 801 and the lower blade 802 are arranged opposite each other, close to but not in contact with the filter plate 2 of the ceramic filter. The distance between the cutting edges of the upper blade 801 and the end face of the oscillating scraper 8 is 2 mm. The angle between the cutting edge of the upper blade 801 and the end face of the oscillating scraper 8 is 60° to reduce the resistance to cutting into the mineral deposits and make the blade tip cut into the mineral deposits more smoothly. The cutting edge of the lower blade 802 is set straight, and further scrapes off the residual minerals when oscillating downwards. An oscillating motor 6 is connected to the side of the rotating shaft 5. By setting up the upper and lower blades, the oscillating motor 6 can repeatedly scrape off the mineral deposits on the filter plate 2 of the ceramic filter when running.

[0021] A switch bracket 9 is welded to the side of the oscillating scraper bracket 41 near the filter plate. A laser beam switch 7 is fixed to the switch 9 by bolts. The laser beam switch 7 is located in front of the filter plate 2 of the ceramic filter. The transmitting and receiving ends of the laser beam switch 7 are located on the left and right sides of the filter plate 2, respectively. The optical path is perpendicular to the left and right sides of the filter plate 2, and the vertical distance from the front edge of the filter plate 2 is 3cm. The signal output end of the laser beam switch 7 is electrically connected to the controller of the oscillating motor 6. By setting the switch bracket 9, the position of the laser beam switch 7 can be adjusted according to production conditions to prevent the filter plate from being damaged by mineral accumulation.

[0022] The top of the swing scraper bracket 4 is about 15cm higher than the highest point of the ceramic filter scraper 3. By raising the swing scraper 8 bracket, mechanical interference with the original equipment can be avoided.

[0023] The usage process of this utility model is as follows: After the device is powered on, the laser beam switch 7 continuously emits a beam. If the light path is not blocked, the swing motor 6 is in standby mode, and the swing scraper 8 remains stationary in the vertical direction. When the ceramic filter plate 2 is running, minerals gradually accumulate on the left, right, and front sides of the ceramic filter plate 2 and block the light path of the laser beam switch 7 for 5 seconds, the laser beam switch 7 immediately sends a trigger signal to the swing motor 6. After receiving the signal, the swing motor 6 causes the swing scraper 8 to cut into the accumulated mineral layer clockwise along the rotating shaft 5. The rotating shaft 5 drives the swing scraper 8 to rotate 90° clockwise along the rotating shaft 5 and then swing counterclockwise, so that the swing scraper 8 returns to the vertical state. The upper blade 801 cuts into the accumulated mineral layer at an inclined angle to initially scrape off the accumulated minerals, and the lower blade 802 scrapes off the loose minerals. The cleaned minerals fall downwards. When the mineral accumulation is completely cleared, the light path of the laser beam switch 7 is restored, the controller cuts off the power to the swing motor 6, the swing scraper 8 stops swinging, and returns to the standby state.

[0024] In different embodiments, the position of the laser beam switch 7 on the switch bracket 9 can be adjusted by bolts to adapt to the detection needs of different mineral accumulation levels.

[0025] In different embodiments, the blade tip angle of the upper blade 801 is 45°. The greater the hardness of the mineral deposits on the filter plate 2 of the ceramic filter, the smaller the blade tip angle of the upper blade 801.

[0026] This device achieves real-time monitoring and efficient cleaning of mineral deposits through laser triggering, motor drive, and the synergistic effect of dual blades, significantly reducing the risk of filter plate breakage. It is suitable for ceramic filter systems with high-load continuous production.
