Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a low-pressure membrane shell for water treatment. Background Art

[0002] The low-pressure membrane housing for water treatment is an important component of the low-pressure membrane water purifier. It is used to accommodate and protect the low-pressure membrane system to ensure its normal and efficient operation. The membrane housing end cover is a sealing and waterproof device for water treatment containers. Due to installation, use, cleaning and replacement, it is often necessary to remove the membrane housing cover, pull out the pressure-bearing parts, and clean or replace the reverse osmosis membrane in the membrane housing.

[0003] In the prior art, the pressure-bearing parts are generally fixed inside the membrane shell by three sets of independently arranged blocks and bolts, which results in the need to be installed and disassembled in groups, which is inefficient. For this reason, we propose a low-pressure membrane shell for water treatment. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a low-pressure membrane shell for water treatment, comprising a pressure-bearing part, which can be inserted into the inner cavity of the membrane shell and locked by a locking assembly, wherein the locking assembly comprises a connecting part, a first adjusting part, a second adjusting part, a third adjusting part, a limiting part and a first slot, wherein the connecting part is installed at one end of the pressure-bearing part, the external thread of the connecting part is connected to the first adjusting part, the first adjusting part is rotatably connected to the second adjusting part, the outer wall of the second adjusting part is circumferentially equidistantly hinged to three groups of the third adjusting parts, the other end of the third adjusting part is hinged to the limiting part, the limiting part is slidably connected to the pressure-bearing part, and can be inserted into the first slot opened in the inner cavity of the membrane shell.

[0006] Preferably, the limiting member includes a first limiting block and a second limiting block, the second limiting block is integrally formed at one end of the first limiting block, the second limiting block is hinged to one end of the third adjusting member, and the second limiting block is slidably connected to a slider installed on the pressure-bearing member.

[0007] Preferably, the slider is specifically a T-shaped structural member, and the slider is detachably connected to the pressure-bearing member by bolts.

[0008] Preferably, a spring is installed on one side of the sliding block, and the other end of the spring is connected to an inner cavity of the second limiting block away from one end of the first limiting block.

[0009] Preferably, two groups of second grooves are formed on the outer wall of the pressure-bearing member, and sealing rings can be installed in the two groups of the second grooves to achieve a sealed connection between the pressure-bearing member and the membrane shell.

[0010] Preferably, a connecting pipe is installed through the outer wall of the membrane shell, and a gasket is provided in the inner cavity of the connecting pipe.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model drives the second adjusting member to move by rotating the first adjusting member threadedly connected to the connecting member, so that the second adjusting member drives the third adjusting member to move, and then drives the limiting member to slide along the pressure-bearing member, and can be inserted into the first slot to lock and limit the pressure-bearing member, or release the lock and pull out the pressure-bearing member. Compared with the prior art, multiple groups of limiting members can be adjusted at the same time, and the adjustment efficiency is higher, which helps to improve the disassembly and assembly efficiency.

[0013] 2. The utility model installs a sealing ring in the second slot, so that when the pressure-bearing part is inserted into the membrane shell, a sealed connection between the two can be achieved. The third adjusting part can push the second limit block to slide along the T-shaped slider, so that the first limit block can be inserted into the first slot and squeeze the spring. Conversely, when unlocked, the spring resets and can assist the first limit block to disengage from the first slot. The bolt passes through the slider and is threadedly connected to the pressure-bearing part to complete the fixation of the slider, which is convenient for disassembly and assembly. The inner wall of the connecting part is also provided with threads, which can be connected to the blocking part or the pipeline. The gasket is specifically a sealing gasket, and the inner wall of the connecting pipe is also provided with threads, which can be threadedly connected to the pipeline and sealed with the gasket.
