A utility model patent with authorization announcement number CN2533874Y discloses a multi-stage pharmaceutical solution filter that can improve the filtration rate without affecting the infusion flow rate. It consists of a liquid inlet, a shell, a primary filter membrane, a medium-efficiency filter membrane, a high-efficiency filter membrane, and a liquid outlet. The liquid sequentially passes through these components for multi-stage filtration, achieving both improved filtration rate and no reduction in infusion flow rate without increasing the cross-sectional area of ​​the pharmaceutical solution filter. This utility model is particularly suitable for high-efficiency pharmaceutical solution filters.

[0003] However, this device has some shortcomings. Impurities generated during the filtration of the medicine remain on the filter screen, which can cause the filter screen to become clogged. At the same time, the impurities on the filter screen are difficult to clean, affecting the next use of the device. Utility Model Content

[0004] The purpose of this invention is to provide a multi-stage precision filtration device for bactericide and algaecide solutions, which solves the problem that impurities generated during the filtration of the solution remain on the filter screen, causing filter screen blockage. At the same time, the impurities on the filter screen are difficult to clean, affecting the next use of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage precision filtration device for bactericidal and algaecide liquid, comprising a tank, a support foot fixedly connected to the lower end of the tank, a support rod fixedly connected to the upper end of the tank, a guide bucket fixedly connected to the upper end of the support rod, a flipping mechanism provided on the tank, a cylinder provided on the flipping mechanism, a filter screen fixedly connected inside the cylinder, and a cleaning mechanism provided on the cylinder.

[0006] Preferably, the flipping mechanism includes a support shaft, which is fixedly connected to the surface of the cylinder. The support shaft and the tank are connected via bearings.

A spring is provided on the outside of the slide rod. A connecting plate is fixedly connected to the other end of the slide rod, and a pin is fixedly connected to the surface of the connecting plate. The pin is slidably connected to the tank. The connecting plate drives the slide rod to rotate, which in turn causes the support shaft to drive the cylinder to rotate, allowing the cylinder to flip. This, in turn, causes the filter screen to flip, allowing water to enter through the guide bucket to rinse the filter screen, making it easier to clean the impurities attached to the filter screen.

[0007] Preferably, a sliding pin is fixedly connected to the surface of the baffle, and the sliding pin is slidably connected to the support shaft. By providing the sliding pin, rotation of the baffle relative to the support shaft is prevented.

[0010] Preferably, a guide block is fixedly connected inside the slip ring, and the guide block is slidably connected to the spindle. By providing the guide block, rotation of the slip ring and the spindle is prevented.

[0011] Preferably, one end of the compression spring is fixedly connected to the retaining ring, and the other end of the compression spring contacts the slip ring. By setting the compression spring, the slip ring is elastically compressed downwards.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a connecting plate to drive the sliding rod to rotate, which in turn causes the support shaft to drive the cylinder to rotate, allowing the cylinder to flip over. This causes the filter screen to flip over, and water can be introduced through the guide bucket to wash the filter screen, making it easier to clean the impurities attached to the filter screen.

[0014] 2. This utility model uses a motor to drive the main shaft to rotate, which in turn causes the slip ring to drive the scraper to rotate. At the same time, a compression spring acts on the slip ring, so that the scraper is always pressed against the filter screen. This makes it easy to clean impurities during the filtration process and ensures filtration efficiency. Attached Figure Description

The baffle 53 is slidably connected to the support shaft 51. A sliding pin 54 is fixedly connected to the surface of the baffle 53. The sliding pin 54 is slidably connected to the support shaft 51. By setting the sliding pin 54, the baffle 53 is prevented from rotating relative to the support shaft 51. A spring 55 is set on the outside of the slide rod 52. One end of the spring 55 is connected to the support shaft 51. Shaft 51 is fixedly connected, and the other end of spring 55 is fixedly connected to baffle 53. By setting spring 55, baffle 53 can be easily reset. The other end of slide rod 52 is fixedly connected to connecting plate 56. Pin 57 is fixedly connected to the surface of connecting plate 56. Pin 57 is slidably connected to tank 1. The connecting plate 56 drives slide rod 52 to rotate, which in turn drives support shaft 51 to rotate cylinder 6, so that cylinder 6 can be flipped, which in turn makes filter screen 7 flipped. Water enters through guide bucket 4 to wash filter screen 7, making it easier to clean the impurities attached to filter screen 7.

[0023] Please see Figure 2 , Figure 4 The cleaning mechanism 8 includes a support plate 81. The support plate 81 is fixedly connected inside the cylinder 6. A motor 82 is fixedly connected to the lower end of the support plate 81. The rotating shaft of the motor 82 passes through the support plate 81 and is rotatably connected to it.

By setting the guide block, the rotation of the slip ring 85 and the main shaft 83 is prevented. A compression spring 86 is provided on the outer side. One end of the compression spring 86 is fixedly connected to the retaining ring 84, and the other end of the compression spring 86 contacts the slip ring 85. By setting the compression spring 86, the slip ring 85 is elastically compressed downward. A scraper 87 is fixedly connected to the surface of the slip ring 85. The scraper 87 is slidably connected to the filter screen 7. By setting the motor 82 to drive the main shaft 83 to rotate, the slip ring 85 drives the scraper 87 to rotate. At the same time, the compression spring 86 acts on the slip ring 85, so that the scraper 87 is always pressed on the filter screen 7, making it easy to clean impurities during the filtration process and ensuring filtration efficiency.

[0024] The specific implementation process of this utility model is as follows: In use, the medicine is poured into the guide bucket 4 and then into the cylinder 6, where it is filtered by the multi-layer filter screen 7. The reporting motor 82 is started, and the motor 82 drives the main shaft 83 to rotate. The main shaft 83 drives the slip ring 85 to rotate, which in turn drives the scraper 87 to rotate. At the same time, the compression spring 86 acts on the slip ring 85, so that the scraper 87 is always pressed on the filter screen 7, making it easy to clean impurities during the filtration process and ensuring filtration efficiency. After use, the connecting plate 56 is manually moved. The movement of the connecting plate 56 drives the slide rod 52 to move, which in turn drives the baffle 53 to move, thus compressing the spring 55. Then, the connecting plate 56 drives the slide rod 52 to rotate, which in turn drives the support shaft 51 to rotate the cylinder 6, allowing the cylinder 6 to flip over. This causes the filter screen 7 to flip over, and water is introduced through the guide bucket 4 to rinse the filter screen 7, making it easy to clean the impurities attached to the filter screen 7.
