Description

Technical Field

[0001] This utility model belongs to the technical field of water treatment devices, and in particular relates to an adapter for a separator membrane housing. Background Technology

[0002] The membrane housing is an important component of the membrane element in membrane water treatment projects, possessing excellent sealing performance and providing a stable water pressure environment for the internal membrane element. The adapter connects the membrane element to the purified water outlet. It features a central purified water flow channel and a structure that is thicker in the middle and thinner at both ends. The relatively thinner ends are inserted into the central tube of the membrane element and the purified water outlet, respectively. Water treated by the membrane element flows out through the adapter from the purified water outlet. The adapter is sealed to both the central tube of the membrane element and the purified water outlet using sealing rings.

[0003] Traditional adapters have a cylindrical outer contour in the middle section. When assembling axially with the membrane element's central tube and the purified water outlet, the sealing ring creates assembly resistance, and the smooth outer surface of the cylindrical structure makes it difficult to grip. Especially during axial removal of the adapter, one end of the cylindrical structure is tightly fitted to the component and cannot serve as an axial force-bearing surface. Sufficient axial removal force can only be obtained by increasing the normal pressure on the cylindrical surface to increase friction, leading to assembly difficulties. Furthermore, the thick wall of the middle section results in material waste. Utility Model Content

[0004] In view of this, to address the problems of traditional adapters having a cylindrical outer contour in the middle section, which leads to assembly difficulties and material waste due to the thick wall of the middle section, this utility model proposes an adapter for a separator membrane housing. The middle section structure of the adapter is improved by using a ribbed structure instead of the original cylindrical structure, facilitating axial assembly. The ribbed structure not only meets the strength requirements of the adapter but also saves a significant amount of raw materials, reducing production costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adapter for a separator membrane housing, comprising a stepped shaft composed of three coaxial cylindrical sections, wherein the three coaxial cylindrical sections of the stepped shaft are, in sequence along the axial direction, an inlet cylindrical section, a middle cylindrical section, and a drain cylindrical section. Both ends of the middle cylindrical section are provided with annular ribs in the circumferential direction. The outer diameter of the annular ribs is larger than the diameter of the inlet cylindrical section and larger than the diameter of the drain cylindrical section. A clean water flow channel is axially penetrated inside the stepped shaft.

[0006] Furthermore, the outer surface of the middle cylindrical section is provided with multiple reinforcing ribs along the axis, and the two ends of the reinforcing ribs are connected to the annular rib plate.

[0007] Furthermore, there are four reinforcing ribs, evenly distributed along the circumference of the middle section of the cylinder.

[0008] Furthermore, the diameter of the drainage section cylinder is larger than the diameter of the middle section cylinder, and the diameter of the middle section cylinder is larger than the diameter of the inlet section cylinder.

[0009] Furthermore, an annular groove is formed on the outer surface of the end of the inlet section cylinder that is away from the middle section cylinder.

[0010] Furthermore, there are two annular grooves.

[0011] Furthermore, both ends of the water purification channel are chamfered.

[0012] Furthermore, the purified water channel is a gradually opening channel, with the inner diameter of the purified water channel gradually increasing from the cylindrical inlet section to the cylindrical outlet section.

[0013] Compared with the prior art, the beneficial effects of the adapter for the separator housing described in this utility model are:

[0014] 1. This utility model improves the structure of the middle section of the adapter by changing the traditional cylindrical structure to a ribbed structure, which improves the convenience of the adapter's assembly and disassembly.

[0015] 2. The fluid channel inside the middle section of the adapter is shaped with a gradually increasing diameter, which effectively reduces the flow resistance.

[0016] 3. By improving the structure of the middle section, this utility model reduces the overall weight of the adapter by 30% while meeting the water pressure requirements of the working environment, thereby reducing the amount of material used in the adapter manufacturing process and saving materials.

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other, and the described embodiments are only some embodiments of the present invention, not all embodiments.

[0026] I. Detailed Implementation Method 1, see [link / reference] Figure 1-6 This embodiment describes an adapter for a separator membrane housing, comprising a stepped shaft composed of three coaxial cylindrical sections. The three coaxial cylindrical sections of the stepped shaft are, in sequence along the axial direction, an inlet cylindrical section 1, a middle cylindrical section 2, and a drain cylindrical section 3. Both ends of the middle cylindrical section 2 are provided with annular ribs 4. The outer diameter of the annular ribs 4 is larger than the diameter of the inlet cylindrical section 1 and larger than the diameter of the drain cylindrical section 3. A clean water flow channel 5 is axially penetrating inside the stepped shaft.

[0027] The outer surface of the middle section cylinder 2 is provided with a plurality of reinforcing ribs 6 axially, and the two ends of the reinforcing ribs 6 are connected to the annular rib plate 4.

[0028] There are four reinforcing ribs 6, which are evenly arranged around the circumference of the middle section of the cylinder 2.

[0029] This utility model has a pair of annular ribs 4 circumferentially provided at both ends of the middle section cylinder 2. When axially disassembling and assembling, the inner surfaces of the pair of annular ribs 4 can be used as the force application surfaces to apply axial force. The reinforcing ribs increase the axial friction force, simplify the disassembly and assembly process of the adapter, and realize the efficient disassembly and assembly of the adapter.

[0030] The adapter is designed for environments with different internal and external water pressures, with an internal pressure of approximately 0.3 MPa and an external pressure of approximately 8.1 MPa. This invention features a ribbed structure in the middle section, which, while meeting the strength requirements for both internal and external water pressures, reduces the overall weight of the adapter. The original structure weighed approximately 190 grams, while this new structure weighs approximately 130 grams, a weight reduction of 30%, thus lowering production costs and saving raw materials.

[0031] The diameter of the drainage section cylinder 3 is larger than the diameter of the middle section cylinder 2, and the diameter of the middle section cylinder 2 is larger than the diameter of the inlet section cylinder 1.

[0032] An annular groove 7 is formed on the outer surface of the end of the inlet section cylinder 1 away from the middle section cylinder 2. The annular groove 7 is used to fit a sealing ring. One side of the drain section cylinder 3 is connected to the clean water outlet side end plate 10, and the clean water outlet side end plate is provided with a sealing ring groove.

[0033] There are two annular grooves 7.

[0034] Both ends of the water purification channel 5 are chamfered. The chamfers guide the water flow in and out of the pipe, reducing energy loss of the water flow at the pipe walls at both ends.

[0035] The purified water channel 5 is a gradually opening channel, with its inner diameter gradually increasing from the inlet section cylinder 1 towards the outlet section cylinder 3. The purified water channel 5 of this invention has a gradually increasing diameter internal structure. Combined with the overall structure of the adapter, the diameter of the purified water channel 5 shows a gradually increasing trend within the inlet section cylinder 1 and the outlet section cylinder 3, but the change is relatively small. The increasing diameter trend is more pronounced within the middle section cylinder 2. This gradually increasing diameter reduces wall thickness and material usage, and also effectively reduces channel resistance.

[0036] The embodiments of the present invention disclosed above are merely illustrative of the present invention. The embodiments do not exhaustively describe all details, nor do they limit the present invention to the specific implementations described. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention.
