Technical Field
[0001] This utility model relates to the field of sealing device technology, and in particular to a ceramic membrane pressure sealing device. Background Technology
[0002] Ceramic membranes, also known as inorganic ceramic membranes, are asymmetric membranes formed from inorganic ceramic materials through a special process. Ceramic membranes are divided into two types: tubular ceramic membranes and flat-sheet ceramic membranes. Tubular ceramic membranes have a dense network of micropores in their tube walls. Under pressure, the feed liquid flows inside or outside the membrane tube. Small molecules (or liquids) permeate through the membrane, while large molecules (or solids) are retained, thus achieving separation, concentration, purification, and environmental protection. Flat-sheet ceramic membranes have a dense network of micropores on their surface. Within a certain pore size range, the permeability varies depending on the diameter of the molecules that permeate. Driven by the pressure difference across the membrane, the membrane acts as the filtration medium. Under certain pressure, when the feed liquid flows across the membrane surface, only water, inorganic salts, and small molecules are allowed to permeate, while suspended solids, colloids, and microorganisms are prevented from passing through.
[0003] During the processing, a certain pressure is applied to the ceramic membrane module, causing the fluid to pass through the ceramic membrane under pressure, thereby achieving separation, purification and other purposes. In this process, a sealing device is required to ensure good sealing performance under pressure and prevent fluid leakage.
[0004] However, in the existing technology, the sealing components will wear, age or be damaged during long-term use, and the fluid will leak out from the damaged parts, reducing the actual amount of fluid participating in filtration. This not only reduces the processing capacity, but also causes insufficiently filtered fluid to mix into the filtrate, reducing the filtration accuracy and purity. Therefore, a ceramic membrane pressure sealing device is proposed. Utility Model Content
[0005] The purpose of this invention is to solve the problems existing in the prior art, which not only reduce the processing capacity but also cause insufficiently filtered fluid to mix into the filtrate, thus reducing the accuracy and purity of filtration. Therefore, a ceramic membrane pressure sealing device is proposed.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a ceramic membrane pressure sealing device, comprising a processing barrel, an inner liner fixedly installed inside the processing barrel, six processing grooves opened at the upper end of the inner liner, a pressure mechanism provided above the processing barrel, a sealing quick-installation mechanism provided at the lower end of the pressure mechanism, and the pressure mechanism comprising four support seats, six connecting rods, six threaded cylinders and six pressure heads;
[0007] The sealing quick-release mechanism includes six sets of cylinders. Each of the six sets of cylinders has a nut at its upper end. The outer walls of the six sets of connecting rods are threaded. Sealing discs are slidably fitted onto the outer walls of each of the six sets of threaded cylinders. Lower sealing cylinders are fixedly installed at the lower ends of each of the six sets of sealing discs. Upper sealing cylinders are fixedly installed at the upper ends of each of the six sets of sealing discs. Limiting rings are fixedly installed at the upper ends of each of the six sets of sealing discs. Three sets of circular grooves are formed on the inner walls of both the lower and upper sealing cylinders. Sealing gaskets are installed inside several of these grooves. Five sets of diagonal braces are fixedly installed at the lower ends of each of the six sets of cylinders. Threaded rods are fixedly installed at the lower ends of each of the six sets of connecting rods. The six sets of pressure heads and six sets of sealing discs are respectively located inside the six sets of processing grooves. The six sets of nuts are threadedly connected to the six sets of external threads, and the six sets of threaded rods are threadedly connected to the six sets of threaded cylinders.
[0008] Preferably, a support plate is fixedly installed on the upper end of the four sets of support seats, and four sets of cylinders are installed through the upper end of the support plate. A sealing cover is fixedly installed on the extended end of the four sets of cylinders.
[0009] Preferably, the six sets of lower sealing cylinders and the six sets of upper sealing cylinders are respectively sleeved on the outer walls of the six sets of threaded cylinders, and the outer walls of the several sets of inclined bracing rods are respectively in contact with the inner walls of the six sets of limiting rings.
[0010] Preferably, the inner walls of several sets of sealing gaskets are in contact with the outer walls of six sets of threaded cylinders, and the outer walls of the six sets of sealing discs are in contact with the inner walls of the six sets of machining grooves.
[0011] Preferably, the upper ends of the six sets of connecting rods are all fixed to the lower ends of the sealing caps, the lower ends of the six sets of threaded cylinders are respectively fixed to the upper ends of the six sets of pressure heads, and the outer walls of the four sets of support seats are all fixed to the outer walls of the processing barrel.
[0012] Preferably, a sealing ring gasket is fixedly installed at the lower end of the processing groove, and an annular groove is formed at the upper end of the inner liner. The diameter of the sealing ring gasket is the same as the diameter of the annular groove.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. In this utility model, by setting a sealing quick-installation mechanism, the six sets of processing grooves can be sealed. With the cooperation of the lower sealing cylinder, the upper sealing cylinder and the six sets of sealing gaskets, the fluid can be prevented from leaking out from the damaged parts, and the actual amount of fluid participating in filtration can be prevented from decreasing. This not only does not reduce the processing capacity, but also prevents the fluid that has not been fully filtered from mixing into the filtrate, thus protecting the filtration accuracy and purity. Furthermore, pressure can be applied to the sealing disc, thereby continuously providing thrust to the sealing disc and preventing the sealing disc from moving back and forth on the outer wall of the threaded cylinder when the ceramic membrane is pressurized. This ensures that the sealing disc can maintain a sealing effect. In addition, the sealing disc can be quickly disassembled, making it convenient to replace the sealing disc, the lower sealing cylinder and the upper sealing cylinder.
[0015] 2. In this utility model, by providing a pressurizing mechanism, six sets of pressurizing heads can pressurize the ceramic membranes inside the six processing tanks, thereby facilitating the extrusion of liquid from the ceramic membranes and the filtration of the fluid.

Detailed Implementation
[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0023] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a ceramic membrane pressure sealing device, including a processing barrel 1, an inner liner 11 fixedly installed inside the processing barrel 1, six processing grooves 14 opened at the upper end of the inner liner 11, a pressure mechanism 2 arranged above the processing barrel 1, and a sealing quick-installation mechanism 3 arranged at the lower end of the pressure mechanism 2. The pressure mechanism 2 includes four sets of support seats 21, six sets of connecting rods 25, six sets of threaded cylinders 26 and six sets of pressure heads 27.
[0024] The sealing quick-release mechanism 3 includes six sets of cylinders 31, each with a nut 32 at its upper end. The outer walls of the six sets of connecting rods 25 are threaded with external threads 33. Sealing discs 34 are slidably fitted onto the outer walls of the six sets of threaded cylinders 26. Lower sealing cylinders 35 are fixedly installed at the lower ends of the six sets of sealing discs 34, and upper sealing cylinders 36 are fixedly installed at the upper ends of the six sets of sealing discs 34. Limiting rings 37 are fixedly installed at the upper ends of the six sets of sealing discs 34. Three sets of circular grooves 38 are formed on the inner walls of the six sets of lower sealing cylinders 35 and the six sets of upper sealing cylinders 36. Sealing gaskets 39 are installed inside several of the circular grooves 38. Five sets of diagonal braces 31 are fixedly installed at the lower ends of the six sets of cylinders 31. 0. The lower ends of the six sets of connecting rods 25 are all fixedly installed with threaded rods 311. The six sets of pressure heads 27 and the six sets of sealing discs 34 are respectively set inside the six sets of processing grooves 14. The six sets of nuts 32 are respectively threaded to the six sets of external threads 33. The six sets of threaded rods 311 are respectively threaded to the six sets of threaded cylinders 26. The six sets of lower sealing cylinders 35 and the six sets of upper sealing cylinders 36 are respectively sleeved on the outer wall of the six sets of threaded cylinders 26. The outer walls of several sets of diagonal bracing rods 310 are respectively in contact with the inner walls of the six sets of limiting rings 37. The inner walls of several sets of sealing gaskets 39 are respectively in contact with the outer walls of the six sets of threaded cylinders 26. The outer walls of the six sets of sealing discs 34 are respectively in contact with the inner walls of the six sets of processing grooves 14.
[0025] The specific settings and functions of this embodiment are described in detail below. By opening three sets of circular grooves 38 inside both the lower sealing cylinder 35 and the upper sealing cylinder 36, and inserting six sets of sealing gaskets 39 into the six sets of circular grooves 38 respectively, the sealing circular plate 34 is picked up and placed on the outer wall of the threaded cylinder 26, and the threaded cylinder 26 is pushed downward until the lower end of the lower sealing cylinder 35 contacts the upper end of the pressure head 27. At this time, the outer wall of the sealing circular plate 34 contacts the inner wall of the processing groove 14, thereby sealing the six sets of processing grooves 14. With the cooperation of the lower sealing cylinder 35, the upper sealing cylinder 36 and the six sets of sealing gaskets 39, the fluid can be prevented from leaking out from the damaged part, and the actual amount of fluid participating in filtration can be prevented from decreasing. This will not only not reduce the processing capacity, but also prevent the fluid that has not been fully filtered from mixing into the filtrate, thus preventing the filtration accuracy and purity from being compromised.
[0026] By rotating the nut 32, the nut 32 moves downward along the external thread 33, pushing the cylinder 31 to slide downward on the outer wall of the connecting rod 25. At the same time, the cylinder 31 moves downward along the five sets of diagonal braces 310 until they contact the upper end of the sealing disc 34. The outer wall of the five sets of diagonal braces 310 contacts the inner wall of the limiting ring 37, which limits the five sets of diagonal braces 310. The sealing disc 34 drives the lower sealing cylinder 35 and the upper sealing cylinder 36 to slide downward on the outer wall of the threaded cylinder 26 until the lower end of the lower sealing cylinder 35 contacts the upper end of the pressure head 27. This applies pressure to the sealing disc 34, providing continuous thrust and preventing the sealing disc 34 from moving back and forth on the outer wall of the threaded cylinder 26 when the ceramic membrane is pressurized. This ensures that the sealing disc 34 maintains a continuous sealing effect.
[0027] By rotating the pressure head 27, the pressure head 27 will drive the threaded cylinder 26 to rotate, causing the threaded cylinder 26 to rotate on the outer wall of the threaded rod 311 until the threaded cylinder 26 spirals off the outer wall of the threaded rod 311. Then, the sealing disc 34 slides upward until the sealing disc 34 separates from the outer wall of the threaded cylinder 26. The sealing disc 34 will drive the lower sealing disc 35 and the upper sealing disc 36 to move together, thereby enabling the sealing disc 34 to be quickly disassembled and facilitating the replacement of the sealing disc 34, the lower sealing disc 35, and the upper sealing disc 36.
[0028] Example 2: Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the pressurizing mechanism 2 includes four sets of support seats 21, six sets of connecting rods 25, six sets of threaded cylinders 26, and six sets of pressurizing heads 27. Support plates 22 are fixedly installed on the upper ends of the four sets of support seats 21. Four sets of cylinders 23 are installed through the upper ends of the support plates 22. Sealing covers 24 are fixedly installed on the extended ends of the four sets of cylinders 23. The upper ends of the six sets of connecting rods 25 are all fixed to the lower ends of the sealing covers 24. The lower ends of the six sets of threaded cylinders 26 are respectively fixed to the upper ends of the six sets of pressurizing heads 27. The outer walls of the four sets of support seats 21 are all fixed to the outer walls of the processing barrel 1.
[0029] A sealing ring gasket 12 is fixedly installed at the lower end of the processing groove 14, and a ring groove 13 is opened at the upper end of the inner liner 11. The diameter of the sealing ring gasket 12 is the same as the diameter of the ring groove 13.
[0030] The overall effect of this embodiment is that by simultaneously activating four sets of cylinders 23, the extended ends of the four sets of cylinders 23 push the sealing cover 24 downward. The sealing cover 24 drives the six sets of threaded cylinders 26 downward through the six sets of connecting rods 25. The six sets of threaded cylinders 26 drive the six sets of pressure heads 27 to move downward inside the six sets of processing grooves 14, thereby facilitating the pressure of the six sets of pressure heads 27 on the ceramic membrane inside the six sets of processing grooves 14, thus facilitating the squeezing out of the liquid in the ceramic membrane and facilitating the filtration of the fluid.
[0031] When the sealing cover 24 is pushed down, the sealing cover 24 drives the sealing ring gasket 12 to move into the ring groove 13, which can achieve a sealing effect and increase the practicality of the device.
[0032] By providing guide holes at the bottom of the six sets of processing grooves 14, it is convenient for the fluid at the pressurization point to be discharged from the guide holes.
[0033] The method of use and working principle of this device are as follows: First, insert the six sets of sealing gaskets 39 into the six sets of circular grooves 38 respectively. Then, lift the sealing circular plate 34 and place it on the outer wall of the threaded cylinder 26, and push the threaded cylinder 26 downward until the lower end of the lower sealing cylinder 35 contacts the upper end of the pressure head 27. At this time, the outer wall of the sealing circular plate 34 contacts the inner wall of the processing groove 14, thereby achieving a sealing effect on the six sets of processing grooves 14. Then, by rotating the pressure head 27, the pressure head 27 will drive the threaded cylinder 26 to rotate, making... The threaded cylinder 26 rotates threadedly on the outer wall of the threaded rod 311 until it is fixed to the outer wall of the threaded rod 311. Then, by rotating the nut 32, the nut 32 will move downward along the external thread 33, causing it to push the cylinder 31 to slide downward on the outer wall of the connecting rod 25. At the same time, the cylinder 31 will move the five sets of diagonal braces 310 downward until they contact the upper end of the sealing disc 34, and the outer walls of the five sets of diagonal braces 310 contact the inner wall of the limiting ring 37. The limiting ring 37 can control the five sets of diagonal braces. The strut 310 acts as a limit, while the sealing disc 34 causes the lower sealing cylinder 35 and the upper sealing cylinder 36 to slide downwards on the outer wall of the threaded cylinder 26 until the lower end of the lower sealing cylinder 35 contacts the upper end of the pressure head 27. This applies pressure to the sealing disc 34, preventing it from moving back and forth on the outer wall of the threaded cylinder 26. Then, by placing six sets of ceramic membranes into the six sets of processing grooves 14 and adding fluid to the connecting pipe of the processing barrel 1, the fluid flows into the six sets of processing grooves 14 respectively. The fluid flows internally and is filtered by six sets of ceramic membranes. Finally, four sets of cylinders 23 are activated simultaneously. The extended ends of the four sets of cylinders 23 push the sealing cover 24 downward. The sealing cover 24 drives the six sets of threaded cylinders 26 downward through the six sets of connecting rods 25. The six sets of threaded cylinders 26 drive the six sets of pressure heads 27 to move downward inside the six sets of processing tanks 14, so that the six sets of pressure heads 27 can pressurize the ceramic membranes inside the six sets of processing tanks 14, which facilitates the filtration of the fluid. Finally, the pressure is increased again.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
