Description

Technical Field

[0001] This utility model relates to the field of ultrapure water equipment technology, specifically to an RO reverse osmosis membrane pure water equipment. Background Technology

[0002] Ultrapure water equipment, also known as pure water equipment, is a device that can produce water with extremely high purity. Ultrapure water equipment typically uses processes such as reverse osmosis and microfiltration to remove impurities such as ions, large molecular organic matter, and microorganisms from the water. It performs multi-stage purification treatment, such as membrane separation, on raw water such as tap water to obtain water with extremely high purity.

[0003] In RO reverse osmosis pure water equipment, the RO reverse osmosis membrane module (pressure vessel containing RO membrane) is designed to be placed horizontally and supported on both sides by two support bases. After the inlet and outlet of the RO reverse osmosis membrane module are connected to the corresponding components, in order to enhance the stability of the RO reverse osmosis membrane module, clamps and screws are designed on the support bases to strengthen the fixation of the RO reverse osmosis membrane module.

[0004] In the semiconductor manufacturing process, the requirements for water quality are extremely strict. Even a trace amount of impurities can affect the quality and performance of the chip. Therefore, RO reverse osmosis membrane pure water equipment is usually required to produce ultrapure water. Because semiconductor manufacturing has stricter requirements for water quality, the maintenance cycle of the RO reverse osmosis membrane module in traditional RO reverse osmosis membrane pure water equipment is shorter and more frequent than in other scenarios. The existing technology that uses clamps and screws on the support base to strengthen the fixation of the RO reverse osmosis membrane module requires tightening or loosening multiple screws every time it is installed or disassembled, which is relatively cumbersome and increases the difficulty of installation and disassembly. The entire installation and disassembly process takes a long time. Therefore, an RO reverse osmosis membrane pure water equipment is proposed. Utility Model Content

[0005] Based on the above description, this utility model provides an RO reverse osmosis membrane pure water device, which solves the technical problems pointed out in the background art.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An RO reverse osmosis membrane pure water device includes a first water pump, a pressure vessel, a second water pump, and a water storage tank connected in series. The pressure vessel contains an RO reverse osmosis membrane, and the device further includes:

[0007] The positioning assembly includes two sets of positioning plates, each set of positioning plates having an opening. A stop block is fixed on one side of the positioning plate, and a side-push cylinder is hinged to the other side. A placement area is formed between the stop block and the opening for accommodating a pressure vessel. The top end of the side-push cylinder is connected to a pressure plate via a hinge. Both sides of the pressure plate are hinged to the corresponding positioning plates via connecting plates, and the head end is located above the placement area.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, inner blocks are installed at the bottom of the pressure plate head and on the inner side of the placement area.

[0010] Furthermore, it also includes two sets of support components, which are located between the two positioning components.

[0011] Furthermore, the support assembly includes an upright plate on which multiple upright blocks are mounted, and a support plate is fixed between the tops of the multiple upright blocks.

[0012] Furthermore, a telescopic component is installed on the upright plate, and the piston rod of the telescopic component is fixed to the upper top plate, with multiple upright blocks installed on the upper top plate.

[0013] Furthermore, the telescopic component is either a cylinder or an electric push rod.

[0014] Furthermore, a limit block is fixed to the upright plate by bolts, and the limit block is located above the upper top plate.

[0015] Furthermore, the top of the support plate is concave and adapted to the pressure vessel.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0017] This RO reverse osmosis membrane pure water equipment, through its positioning components and two sets of positioning plates with top openings, can stably place the pressure vessel, ensuring that it will not shift or loosen. The side-push cylinder can move the pressure plate by pushing it, thereby pressing the pressure vessel. This allows for quick and precise fixation of the pressure vessel, significantly improving the installation stability and ease of operation, increasing efficiency, and eliminating the need for disassembling and assembling some screws, thus reducing the difficulty of disassembly and assembly.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] like Figure 1-3 As shown, an RO reverse osmosis membrane pure water device in this embodiment includes a first water pump 1, a pressure vessel 6, a second water pump 3, and a water storage tank 2 installed on the device frame. The water guide pipe of the first water pump 1 and the water pump end of the second water pump 3 are respectively fixed to the inlet and outlet of the pressure vessel 6 by clamps. The inlet of the water storage tank 2 is connected to the water guide pipe of the second water pump 3. This is prior art and will not be described in detail. As the focus of this application, the RO reverse osmosis membrane pure water device also includes two positioning components 4 and two sets of support components 5 on the same axis. The support components 5 are located between the two sets of positioning components 4, and the two sets of positioning components 4 fix the pressure vessel 6.

[0025] In the above structure, when installing the pressure vessel 6, the positioning component 4 can support and position the pressure vessel 6, while the support component 5 can support the pressure vessel 6. Therefore, the load on the positioning component 4 can be reduced, and the stability can be improved.

[0026] like Figure 2 The positioning component 4 includes a positioning plate 41 installed on the equipment frame. The top of the positioning plate 41 has an opening, and a stop block 42 opposite to the opening is fixed on the front. A side-push cylinder 44 is hinged to the back. A convex placement area is formed between the stop block 42 and the opening. The piston rod of the side-push cylinder 44 is hinged to a pressure plate 45. The head end of the pressure plate 45 is located above the placement area. The left and right sides of the pressure plate 45 are hinged to the positioning plate 41 through connecting plates.

[0027] The pressure vessel 6 can be placed between the two placement areas, which also serve as a limit. Then, the cylinder 44 pushes one side of the pressure plate 45 upward. Under the action of the connecting plate hinge, the head end of the pressure plate 45 can press down and fix the pressure vessel 6, thus completing the quick installation and fixing, and improving the efficiency of disassembly and assembly.

[0028] The top of the positioning plate 41 is fixed with a protrusion, and the bottom of the pressure plate 45 is fixed with a concave block opposite to the protrusion. The protrusion and the concave block are matched to limit the pressure plate 45, thereby controlling the downward pressure of the pressure plate 45 and preventing the pressure plate 45 from colliding with the positioning plate 41.

[0029] In addition, inner blocks 43 are fixed to the inner side of the opening of the positioning plate 41, the bottom of the stop block 42 and the head end of the pressure plate 45. The inner blocks 43 are all rubber blocks. Under the action of the inner blocks 43, the friction force can be increased and the buffering can be improved. When the pressure plate 45 is pressed down and fixed, it can prevent damage to the outside of the pressure vessel 6.

[0030] like Figure 3 The support assembly 5 includes a vertical plate 51 fixed on the equipment frame, an upper top plate 53 installed on the vertical plate 51, three sets of vertical blocks 54 fixed on the top of the upper top plate 53, and a support plate 55 that supports the pressure vessel 6 fixed between the tops of the three sets of vertical blocks 54. The top of the support plate 55 is concave and adapted to the pressure vessel 6.

[0031] The support plate 55 supports the pressure vessel 6, reducing the load on the positioning plate 41. At the same time, the concave surface of the support plate 55 can also limit the pressure vessel 6.

[0032] The front of the upright plate 51 is equipped with a telescopic component 52. The piston rod of the telescopic component 52 is fixed to the upper top plate 53. The telescopic component 52 can push the upper top plate 53 to move upward, so that the support plate 55 can be pushed upward by the upright block 54, thereby making the support plate 55 fit more closely with the pressure vessel 6. In addition, the pressure plate 45 can also improve the firmness of the clamping of the pressure vessel 6.

[0033] It should be noted that the telescopic component 52 is one of a cylinder or an electric push rod. A limit block 56 is fixed on the upright plate 51 by bolts. The limit block 56 is located above the upper top plate 53. The distance between the limit block 56 and the upper top plate 53 is greater than the diameter of the pressure vessel 6. In this way, when it is necessary to push the pressure vessel 6 out of the placement area, it can be conveniently pushed out by the telescopic component 52.

[0034] In addition, two sets of protruding plates are formed on the top of the upright plate 51, and concave blocks are also installed at the bottom of the protruding plates. A protruding block opposite to the concave block is fixed on the top of the upper top plate 53. With the cooperation of the concave block and the protruding block, the upper top plate 53 can be raised and lowered to a limited position.

[0035] The working principle of the above embodiments is as follows:

[0036] During installation, the pressure vessel 6 is placed in the placement area on the two positioning plates 41, while the support plate 55 supports the pressure vessel 6. After the pressure vessel 6 is securely placed, the side-push cylinder 44 is activated, which pushes one side of the pressure plate 45 upward. The upward-moving part is partly connected to the side-push cylinder 44, while the other side of the pressure plate 45, or the head end of the pressure plate 45, presses down and fixes the pressure vessel 6, completing the quick installation and fixing, reducing the difficulty of disassembly and assembly, improving the efficiency of disassembly and assembly, and significantly improving the installation stability and operation convenience of the pressure vessel 6. In addition, the pressure vessel 6 can be conveniently pushed out of the placement area by the telescopic component 52 later.

[0037] The entire workflow is now complete, and anything not described in detail in this specification is existing technology known to those skilled in the art.

[0038] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
