Description

Technical Field

[0001] This utility model relates to the field of ceramic membrane module technology, and specifically to an irregularly shaped ceramic membrane module. Background Technology

[0002] Ceramic membrane modules are filtration and separation devices assembled from ceramic membrane elements. Through the sieving action of the membrane, particles, colloids, solutes, etc., can be separated from liquids under pressure. In existing technologies, modules mostly adopt tubular or flat-plate structures, fixing the ceramic membrane inside a shell to form a raw water filtration channel and a product water collection system. They are widely used in solid-liquid separation and purification processes in water treatment, chemical, and food industries.

[0003] Chinese utility model patent CN214715729U discloses a novel ceramic membrane module, which includes "raw water entering the cavity inside the upper end cap from the inlet pipe. Due to the presence of sealant, the raw water flows from the inlet end to the outlet end of the tubular ceramic membrane. Under the filtration action of the tubular ceramic membrane, the filtered clear water enters the central water production pipe through the through hole on the central water production pipe and is finally discharged from the outlet pipe. The concentrated water flows to the outlet end of the tubular ceramic membrane and collects in the cavity inside the lower end cap, and is finally discharged from the concentrated water pipe." However, the tubular ceramic membrane in the patent document is a traditional tubular shape. When arranged, there are gaps inside the module, resulting in low space utilization. Furthermore, the connection structure between the distribution ring and the membrane causes the water flow path to be dispersed, which easily forms flow dead zones. The filtration area is not maximized, affecting the filtration efficiency and uniformity of the module. Utility Model Content

[0004] The purpose of this invention is to provide an irregularly shaped ceramic membrane assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an irregularly shaped ceramic membrane assembly, including a water inlet pipe, the bottom end of which vertically penetrates the middle of the top of a first end cap, the bottom end of the first end cap being screwed to the top opening of a main cylinder, a second end cap being screwed to the bottom opening of the main cylinder, a clean water pipe vertically penetrating the middle of the bottom of the second end cap, a water production center pipe being provided at the top opening of the clean water pipe, the upper and lower ends of the water production center pipe being vertically penetrating the middle of the upper and lower fixing plates respectively, and several irregularly shaped ceramic membranes being vertically penetrating the opposite sides of the upper and lower fixing plates;

[0006] A concentrated water pipe runs vertically through one side of the bottom of the second end cap.

[0007] The beneficial effects of this utility model are as follows: the honeycomb structure design of the hexagonal irregular ceramic membrane achieves a high-density orderly arrangement of the irregular ceramic membrane, which not only increases the effective filtration area per unit volume, but also optimizes the water flow distribution through geometric symmetry, reduces dead zones, and improves filtration efficiency. The water production center pipe is densely covered with water passages, which can accelerate the collection of clean water, and the silicone sealant at the top ensures unidirectional flow and prevents leakage. The overall structure takes into account both filtration flux and system stability.

[0008] To prevent raw water from leaking through the gap between the membrane and the cylinder under pressure, silicone rubber sealant is filled between the main cylinder and the outer side of the irregularly shaped ceramic membrane. This sealant also provides a fixed support for the irregularly shaped ceramic membrane.

[0009] A further configuration is provided: the space between the main cylinder and the outer sides of several irregularly shaped ceramic membranes is filled with silicone rubber sealant.

[0010] By adopting the above technical solution, silicone rubber sealant is filled between the main cylinder and the outer side of the irregular ceramic membrane, which can form an elastic sealing layer between the main cylinder and the membrane element. This can effectively prevent raw water from leaking from the gap between the outer side of the membrane and the cylinder under pressure, and also provide a fixed support for the irregular ceramic membrane, ensuring the integrity of the filtration process and the quality of the produced water.

[0011] To achieve this, hexagonal ceramic membranes are arranged in a honeycomb structure around the central permeate pipe, improving the contact efficiency between the raw water and the membrane, increasing the filtration flux, and reducing the dead zone inside the membrane module:

[0012] Further configuration: several of the irregularly shaped ceramic membranes are hexagonal, and the several irregularly shaped ceramic membranes are arranged in a honeycomb structure around the central water production pipe.

[0013] By adopting the above technical solution, several hexagonal irregular ceramic membranes are arranged in a honeycomb structure around the central water production pipe. This arrangement utilizes geometric characteristics to achieve a tight and orderly arrangement of membrane elements. On the one hand, it maximizes the membrane filtration area per unit volume, improves the contact efficiency between raw water and membrane, and enhances the filtration flux. On the other hand, the symmetry and stability of the honeycomb structure can reduce the dead zone of water flow inside the membrane module, so that the raw water flows evenly through each membrane element.

[0014] To provide rigid support for the irregularly shaped ceramic membrane through the hexagonal insertion holes and fluororubber rings on the upper and lower fixing plates, ensuring the membrane remains stable under water flow impact, and preventing raw water from bypassing the membrane filtration layer at the connection between the membrane and the fixing plate:

[0015] Further configuration: The upper and lower fixing plates are respectively located at the upper and lower ends of the inner wall of the main cylinder. The surfaces of the upper and lower fixing plates are provided with several hexagonal insertion holes. The inner walls of the insertion holes are provided with fluororubber rings. The inner walls of the upper and lower sets of insertion holes are vertically penetrated by both ends of the irregular ceramic membrane.

[0016] By adopting the above technical solution, the hexagonal holes on the surface of the upper and lower fixing plates provide rigid support for the irregular ceramic membrane, ensuring that the irregular ceramic membrane remains stable under the impact of water flow and avoiding membrane damage due to vibration. The design of the fluororubber ring utilizes its chemical corrosion resistance and high elasticity to form a dynamic seal between the membrane and the hole, preventing raw water from bypassing the membrane filtration layer at the connection between the membrane and the fixing plate, ensuring that all raw water must be filtered through the membrane surface, and improving the purity of the produced water.

[0017] To ensure the filtered water can quickly pass through the membrane wall and enter the tube via the water inlets on the surface of the product water central tube, and to guarantee the uniformity of water flow direction through the silicone sealant at the top of the product water central tube:

[0018] Further configuration: the surface of the water production center pipe is provided with several water passage holes, and the top end of the water production center pipe is provided with silicone sealant.

[0019] By adopting the above technical solution, the water passage holes on the surface of the water production center tube allow filtered clean water to quickly pass through the membrane wall and enter the tube. The densely distributed water passage hole design increases the clean water collection area, reduces water flow resistance, and improves water production efficiency. Meanwhile, the silicone sealant at the top of the water production center tube seals the top opening, forcing the clean water to flow only downwards along the tube body, ensuring the single direction of water flow, and preventing water leakage at the top interface, thus ensuring that the produced water is stably discharged from the clean water tube.

[0026] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0027] Please see Figures 1 to 4 A non-circular ceramic membrane assembly includes a water inlet pipe 1, the bottom end of which is vertically inserted through the middle of the top of a first end cap 2. The bottom end of the first end cap 2 is screwed to the top opening of a main cylinder 3. A second end cap 4 is screwed to the bottom opening of the main cylinder 3. A clean water pipe 5 is vertically inserted through the middle of the bottom of the second end cap 4. A water production center pipe 6 is provided at the top opening of the clean water pipe 5. The upper and lower ends of the water production center pipe 6 are vertically inserted through the middle of upper and lower fixing plates 7 respectively. Several non-circular ceramic membranes 8 are vertically inserted through the opposite sides of the upper and lower fixing plates 7.

[0028] A concentrated water pipe 9 is vertically inserted through one side of the bottom of the second end cap 4.

[0029] In this embodiment, as Figure 1 and Figure 3 As shown, the space between the main cylinder 3 and the outer sides of several irregularly shaped ceramic membranes 8 is filled with silicone rubber sealant 301.

[0030] In this embodiment, as Figure 3 and Figure 4 As shown, several irregularly shaped ceramic membranes 8 are hexagonal, and are arranged in a honeycomb structure around the central water production pipe 6.

[0031] In this embodiment, as Figure 1 and Figure 3 As shown, the upper and lower fixing plates 7 are respectively located at the upper and lower ends of the inner wall of the main cylinder 3. Several hexagonal insertion holes 701 are opened on the surface of the upper and lower fixing plates 7. Fluororubber rings 702 are provided on the inner wall of the insertion holes 701. The two ends of the irregular ceramic membrane 8 are vertically penetrated through the inner walls of the upper and lower sets of insertion holes 701.

[0032] In this embodiment, as Figure 1 and Figure 4 As shown, the surface of the water production center pipe 6 is provided with several water passage holes 601, and the top of the water production center pipe 6 is provided with silicone sealant 602.

[0033] The working process of this irregularly shaped ceramic membrane module is as follows:

[0034] When using it for the first time, the operator can first introduce raw water from the top of the inlet pipe 1, so that the raw water flows vertically through the bottom opening of the inlet pipe 1 into the cavity where the first end cap 2 and the main cylinder 3 are connected. At this time, since the bottom of the first end cap 2 and the top opening of the main cylinder 3 are fixed by screws, and the top of the water production center pipe 6 is provided with silicone sealant 602, the raw water will be restricted to flow into the hexagonal irregular ceramic membrane 8 distributed in a ring around the water production center pipe 6. At this time, since the two ends of the irregular ceramic membrane 8 respectively penetrate vertically through the hexagonal insertion holes 701 of the upper and lower fixing plates 7, and the inner wall of the insertion hole 701 is provided with fluororubber ring 702, it can play a sealing role, ensuring that the raw water can only enter the interior of the irregular ceramic membrane 8.

[0035] Under pressure, the raw water will pass through the filter layer of the irregular ceramic membrane 8, and the filtered water will seep through the membrane wall of the irregular ceramic membrane 8 and come into contact with the central water production pipe 6 in the middle. During this period, because the surface of the central water production pipe 6 is densely covered with water passage holes 601, the water will directly enter the interior of the central water production pipe 6 through the water passage holes 601. Since the top of the central water production pipe 6 is sealed with silicone sealant 602, the water can only flow downward and flow downward along the pipe of the central water production pipe 6 until it enters the connected water pipe 5 from the opening at the bottom and is discharged.

[0036] During this period, the concentrated water that does not pass through the irregular ceramic membrane 8 will continue to flow downward along the irregular ceramic membrane 8 until it collects in the internal cavity of the second end cap 4, and finally is discharged outward from the concentrated water pipe 9 on the bottom side of the second end cap 4.

[0037] Throughout the process, the upper and lower fixing plates 7 are fixed to the upper and lower ends of the inner wall of the main cylinder 3, which can ensure the stability of the position of the irregular ceramic membrane 8. The design of the fluororubber ring 702 and the silicone rubber sealant 301 can respectively ensure the sealing and fixation between the irregular ceramic membrane 8 and the fixing plate 7 and the main cylinder 3, preventing the raw water from directly entering the water production center pipe 6 without filtration or from leaking. The water production center pipe 6 collects the filtered clean water through the water passage 601 to achieve the separation and purification of the raw water.
