Description

[0002] The membrane filter cartridge, also known as the membrane filter cartridge, is a filter element that uses a special membrane coating technology. The core is that the surface of the filter cartridge is covered with a very thin filter membrane with a special pore structure. This membrane is usually made of polymer materials (such as polytetrafluoroethylene PTFE) through a special process. It has the characteristics of uniform pore size, high filtration accuracy, good chemical stability, and wear resistance.

[0003] In most existing porous substrate coating technologies, a slurry containing particulate matter is applied to the surface of the porous substrate. The particulate matter in the slurry is enriched on the surface of the porous substrate to form a filter membrane body. The liquid in the slurry can absorb and penetrate the porous substrate through negative pressure and be carried away. The filtration effect and filtration accuracy level of the filter cartridge are enhanced through the filter membrane to form a coated filter cartridge. However, the manual slurry coating method is inefficient, the accuracy is difficult to control, and uneven coating is likely to occur.

[0027] like Figures 1 to 6 As shown, a specific embodiment of the utility model provides a high-efficiency negative pressure deposition equipment for processing a coated filter cartridge, comprising a bottom plate 1, a left side plate 2 and a right side plate 3 are fixedly connected to the top of the bottom plate 1, and a porous substrate 4 is provided on the top of the bottom plate 1; a negative pressure deposition assembly for coating the porous substrate 4 is provided between the left side plate 2 and the right side plate 3, and by setting the negative pressure deposition assembly, a slurry containing particles can be evenly applied to the surface of the porous substrate 4, so that a relatively uniform coating is formed on the surface of the porous substrate 4, and compared with manual coating, the efficiency of the entire device is higher, the negative pressure deposition assembly includes clamping blocks 5 arranged at both ends of the porous substrate 4, a rotating shaft 6 is rotatably connected to the left side plate 2, and a negative pressure pipe 7 is provided in the rotating shaft 6, a nozzle 8 is provided on the top of the porous substrate 4, and two arc covers 9 for recovering the slurry during the coating process are provided on the outer side of the porous substrate 4.

[0028] like Figures 1 to 4As shown, specifically, when slurry is applied to the surface of the porous substrate 4, the porous substrate 4 is placed between the two clamping blocks 5, and a cylinder 13 is fixedly installed on the right side plate 3. The output end of the cylinder 13 is rotatably connected to the clamping block 5 on the right side, and a clamping head sealing ring 14 is provided on the clamping block 5. The cylinder 13 is started to push the clamping block 5 on the right side to gradually move to the left side, so as to fix the porous substrate 4 between the two clamping blocks 5. The porous substrate 4 is sleeved between the two clamping blocks 5 and is clamped and fixed under the action of the cylinder 13 pushing the clamping block 5 on the right side. The clamping head sealing ring 14 is set between the clamping block 5 and the porous substrate 4, which can enhance the sealing of the two ends of the porous substrate 4 when clamping and fixing. A first motor 10 is fixedly installed on the left side plate 2. The output end of the cylinder 13 is rotatably connected to the clamping block 5 on the right side, and a clamping head sealing ring 14 is provided on the clamping block 5. A main gear 11 is fixedly connected to the output shaft, a driven wheel 12 is fixedly installed on the rotating shaft 6, and the main gear 11 is meshed with the driven wheel 12, the rotating shaft 6 is fixedly connected to the clamping block 5 on the left, and the rotating shaft 6 and the inner cavity of the clamping block 5 are hollow, and the negative pressure tube 7 is rotatably connected inside the rotating shaft 6, and the first motor 10 is started to drive the main gear 11 to rotate, so that the main gear 11 drives the rotating shaft 6 to rotate by driving the driven wheel 12, so that the rotation of the rotating shaft 6 can drive the porous substrate 4 to follow the rotation, and its rotation speed is uniform rotation. The negative pressure tube 7 is connected to a device for generating negative pressure from the outside, which is a prior art and will not be described here. The negative pressure tube 7 generates negative pressure to produce an adsorption effect, which is produced on the inner cavity of the porous substrate 4 through the hollow rotating shaft 6 and the clamping block 5.

[0029] like Figures 1 to 4 As shown, specifically, a bracket 15 is fixedly mounted on the bottom plate 1, a second motor 16 is fixedly mounted on the bracket 15, a threaded rod 17 is fixedly connected to the output shaft of the second motor 16, a movable plate 18 is threadedly connected to the threaded rod 17, and the movable plate 18 is slidably connected to the bracket 15, a slurry pipe 19 is fixedly connected to the nozzle 8, and the nozzle 8 is fixedly mounted in the movable plate 18. After the porous substrate 4 is clamped and fixed in the above process, the second motor 16 is started to drive the threaded rod 17 to rotate, so that the movable plate 18 and the nozzle 8 mounted on the movable plate 18 move along the bracket 15. At this time, the slurry pipe 19 is connected to a component that provides slurry from the outside. Thus, the nozzle 8 sprays the slurry outward while the nozzle 8 moves, and the porous substrate 4 is at the bottom end of the nozzle 8, so that the slurry is evenly applied to the porous substrate 4 at the bottom end during the gradual and even movement of the nozzle 8, and the porous substrate 4 rotates at the same time, so that the slurry can be applied to each position on its surface with the cooperation of the nozzle 8, and after the slurry is applied to the surface of the porous substrate 4, the particles in the slurry form a filter membrane on the surface of the porous substrate 4, and the liquid part of the slurry is sucked into the inner cavity of the porous substrate 4 under the adsorption effect of the negative pressure generated in the inner cavity of the porous substrate 4, and reaches the negative pressure tube 7 through the hollow clamp 5 and the rotating shaft 6 to be adsorbed and taken away.

[0030] like Figures 1 to 6 As shown, specifically, the two arc covers 9 are fitted to each other, and a cleaning ring 20 is provided in the two arc covers 9, a middle plate 21 and a side plate 22 are provided on the cleaning ring 20, and the middle plate 21 is fixedly connected to the movable plate 18, the middle plate 21 is fitted to the two arc covers 9, and a gap is left between the side plate 22 and the two arc covers 9, through holes 23 are provided on the two arc covers 9, and recovery boxes 26 are provided at both ends of the arc covers 9. While applying the slurry, due to the spraying of the nozzle 8 and the rotation of the porous substrate 4, a small part of the slurry will drip or be thrown onto the inner cavity surface of the arc cover 9. The setting of the arc cover 9 can block the slurry in time to prevent it from dripping randomly, and it can be recovered. Due to the movement of the movable plate 18, the middle plate 21 can be driven to move, that is, the cleaning ring 20 can be driven to move in the two arc covers 9. Therefore, the middle plate 21 and the two arc covers 9 are attached and moved to clean the slurry attached to the inner surface of the arc cover 9, and the slurry is pushed to move toward the end of the arc cover 9. During the moving cleaning process, the pushed slurry will be in the arc groove between the middle plate 21 and the side plate 22, and flow down to the bottom along the arc groove. When the cleaning ring 20 moves to Figure 4 Position, that is, when the middle plate 21 and the end of the arc cover 9 are in the same plane, the slurry in the arc groove can flow downward and drip into the recovery box 26 at the bottom to be collected. The electric push rod 24 is fixedly connected with a connecting plate 25, and the connecting plate 25 is fixedly connected to the arc cover 9. Recovery boxes 26 are provided at both ends of the arc cover 9. After completing the entire coating process, the electric push rod 24 can be started to make the two connecting plates 25 drive the arc cover 9 to separate, so as to facilitate the removal of the porous substrate 4 after coating.
