Description

Technical Field

[0001] The utility model relates to the field of filters, in particular to a Kay membrane filter. Background Art

[0002] The Kai membrane filter is to filter out impurities from the solution to be treated through the filter and the filter element, and use the filter membrane to screen and separate the particles, particles, bacteria, etc. in the solution. The membrane tube is usually installed through the flower plate in the Kai membrane filter. The existing Kai membrane filter used to filter salt water usually has a number of holes evenly opened on the flower plate, and the membrane tube gap is arranged in the hole. When the solution is added to the filter through the feed port, the solution will cause a certain buoyancy to the membrane tube, so that the membrane tube floats relatively in the hole. At this time, when liquid flows such as liquid inlet at the feed port and liquid discharge at the discharge port occur in the filter, the membrane tube floats accordingly with the flow of the solution, and rubs against the inner wall of the hole of the flower plate, thereby causing damage to the membrane tube and causing the quality of liquid discharge at the discharge port to decrease. When the subsequent process is the ion membrane electrolysis process, the damage of the membrane tube will cause the quality of the salt water to decrease, causing the voltage of the electrolysis process tank to rise, thereby causing the trouble of increased energy consumption. At the same time, it can also cause ion membrane pollution, thereby affecting the service life of the ion membrane. Utility Model Content

[0003] The technical problem to be solved by the utility model is: in order to overcome the deficiencies of the prior art, the utility model provides a membrane filter which can avoid direct friction between the membrane tube and the inner wall of the hole of the flower plate, and effectively prolong the service life of the membrane tube.

[0005] The gap between the traditional membrane tube and the hole of the flower plate is matched, and the flower plate is made of hard material, which is easy to wear the membrane tube. The present application designs a rubber sheath in the hole, and sets the membrane tube in the rubber sheath. The rubber sheath can effectively protect the membrane tube and avoid direct friction between the membrane tube and the flower plate during the flow of liquid.

[0006] Furthermore, the rubber sheath includes a plane part and a lower tube part, the upper end surface of the lower tube part is connected to the lower end surface of the plane part, the lower end surface of the plane part contacts the upper end surface of the flower plate, the lower tube part is inserted into the hole, and the outer wall of the lower tube part and the inner wall of the hole are gap-matched. The connection between the rubber sheath and the hole is completed by crimping the plane part and inserting the lower tube part.

[0007] Furthermore, the lower end surface of the lower tube portion is protruding relative to the lower end surface of the flower plate. In this way, after the membrane tube and the rubber sleeve are matched, since the lower end surface of the lower tube portion is protruding from the lower end surface of the flower plate, even if the membrane tube floats / sways slightly with the flow of liquid, it is still the rubber sleeve that contacts the flower plate, and the membrane tube still does not directly contact the flower plate, thereby further reducing the possibility of wear of the membrane tube.

[0008] Preferably, the radial cross-section of the planar portion is a circular ring, the outer diameter of the circular ring is larger than the diameter of the hole, and when the planar portion is crimped onto the flower plate, relative to the flower plate, the planar portion forms an outer edge crimped onto the outer periphery of the upper section of the hole, which can facilitate the positioning and matching of the rubber sleeve and the hole.

[0009] Furthermore, the rubber sheath further comprises a membrane tube end cap, the membrane tube end cap is arranged above the plane portion, the membrane tube end cap is provided with membrane tube holes corresponding to the number of membrane tubes, and the membrane tube gap is arranged in the membrane tube hole. The membrane tube end cap is integrated on the rubber sheath, and the membrane tube end cap is also made of rubber material. After the membrane tube is installed, the wear of the membrane tube surface during the installation process can be reduced by the characteristics of the rubber material.

[0010] Furthermore, the membrane tube end cover, the plane part and the surface of the flower plate are provided with mounting holes correspondingly, and the mounting holes are provided with fixing bolts for fixing the membrane tube end cover, the plane part and the flower plate.

[0011] Furthermore, a sealing gasket is provided between the plane part and the flower plate, and the fixing bolts press the membrane tube end cover, the plane part, the sealing gasket and the upper end surface of the flower plate. Through the design of the fixing bolts and the sealing gasket, the rubber sleeve can be effectively positioned and fixed to the flower plate as a whole, reducing the risk of the rubber sleeve loosening, and further improving the reliability of the Kai membrane filter.

[0012] The beneficial effect of the utility model is that the Kai membrane filter provided by the utility model has a reasonable structural design, and a rubber sheath is designed on the inner wall of the flower plate hole, which is convenient for the positioning and installation of the membrane tube and the flower plate, and avoids the friction between the membrane tube and the inner wall of the flower plate hole, effectively preventing damage to the membrane tube during liquid flow and extending the service life of the membrane tube.

[0017] The utility model is now described in further detail in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, so they only show the components related to the utility model, and the directions and references (for example, up, down, left, right, etc.) can only be used to help describe the features in the drawings. Therefore, the following specific embodiments are not adopted in a restrictive sense, and the scope of the subject matter claimed is limited only by the attached claims and their equivalents.

[0018] like Figure 1 The Kay membrane filter shown is the best embodiment of the utility model.

[0019] The membrane filter comprises a filter housing 1, a feed port 8 is provided on the lower side wall of the filter housing 1, and a flushing port 9 is provided on the lower side wall corresponding to the other side of the feed port 8. A filtered brine outlet 7 is provided on the upper side wall of the filter housing 1, and a flower plate 2 is fixed in the space between the feed port 8 and the filtered brine outlet 7 in the inner cavity of the filter housing 1.

[0020] In this embodiment, a plurality of holes are evenly opened in a radial pattern on the flower plate 2, and a rubber sheath 5 is fixed in each hole. A film tube 6 is fitted in the gap of each rubber sheath 5.

[0021] Specifically, Figure 2 As shown, the rubber sheath 5 includes a plane portion 5-1, a lower tube portion 5-2 and a membrane tube end cap 5-3. The upper end face of the lower tube portion 5-2 is connected to the lower end face of the plane portion 5-1. The membrane tube end cap 5-3 is arranged on the upper end face of the plane portion 5-1. In actual production, the plane portion 5-1, the lower tube portion 5-2 and the membrane tube end cap 5-3 are usually rubber parts of an integrated structure. The radial cross-section of the plane portion 5-1 is a circular ring, and the outer diameter of the circular ring is greater than the diameter of the hole. The connection between the rubber sheath 5 and the hole is completed by crimping the plane portion 5-1 and plugging the lower tube portion 5-2, that is, the rubber sheath 5 is installed in the hole in a T-shaped sleeve-like structure. The lower end face of the plane portion 5-1 contacts the upper end face of the flower plate 2, and the lower tube portion 5-2 is plugged into the hole, and the outer wall of the lower tube portion 5-2 is gap-matched with the inner wall of the hole. When the rubber sheath 5 is installed in the hole, the flat surface portion 5 - 1 forms an outer edge that is pressed against the outer periphery of the upper section of the hole.

[0022] The traditional membrane tube 6 is matched with the clearance of the hole of the flower plate 2. The flower plate 2 is made of hard material, which is easy to wear the membrane tube 6. The present application designs a rubber sheath 5 in the hole, and the membrane tube end cover 5-3 of the rubber sheath 5 is provided with membrane tube holes corresponding to the number of membrane tubes 6, and the membrane tube 6 is arranged in the membrane tube hole with clearance matching. Since the membrane tube end cover 5-3 is made of rubber material, the wear on the outer surface of the membrane tube 6 can be effectively reduced during the positioning and installation of the membrane tube 6 and the rubber sheath 5. At the same time, the membrane tube 6 is arranged in the rubber sheath 5, and the rubber sheath 5 can effectively protect the membrane tube 6 to avoid direct friction between the membrane tube 6 and the flower plate 2 during the flow of liquid.

[0023] At the same time, the lower end surface of the lower tube portion 5-2 of this embodiment is protruding relative to the lower end surface of the flower plate 2. After the membrane tube 6 is matched with the rubber sleeve, the lower end surface of the lower tube portion 5-2 protrudes from the lower end surface of the flower plate 2. With this design, even if the membrane tube 6 floats / sways slightly with the flow of liquid, it is still the rubber sleeve that contacts the flower plate 2, and the membrane tube 6 still does not come into direct contact with the flower plate 2, thereby further reducing the possibility of wear of the membrane tube 6.

[0024] In this embodiment, the rubber sheath 5 is locked and fixed to the flower plate 2 by using fixing bolts 3 and sealing gaskets 4. Specifically, the membrane tube end cap 5-3, the plane portion 5-1 and the surface of the flower plate 2 corresponding to the plane portion 5-1 are provided with mounting holes, and the mounting holes are provided with fixing bolts 3 for fixing the membrane tube end cap 5-3, the plane portion 5-1 and the flower plate 2. A sealing gasket 4 is provided between the plane portion 5-1 and the flower plate 2, and the fixing bolts 3 cooperate with the mounting holes to press the membrane tube end cap 5-3, the plane portion 5-1, the sealing gasket 4 and the upper end surface of the flower plate 2. In actual design, the fixing bolts 3 and the sealing gaskets 4 can usually be designed as multiple groups, surrounding the inner membrane tube, and evenly distributed on the rubber sheath 5 in a ring shape. Through the cooperation of bolts and gaskets, the rubber sleeve can be effectively positioned and fixed to the flower plate 2, reducing the risk of loosening of the rubber sleeve, and further improving the reliability of the Kai membrane filter.
