Description

Technical Field

[0001] The utility model relates to the technical field of reverse osmosis membranes, in particular to a shell for a high-flux reverse osmosis membrane element. Background Art

[0002] The principle of reverse osmosis technology is to separate these substances and water under the action of a higher osmotic pressure than the solution, based on the fact that other substances cannot pass through the semipermeable membrane. The pore size of the reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in the water. The system has the advantages of good water quality, low energy consumption, no pollution, simple process, and easy operation;

[0003] The existing high-flux reverse osmosis membrane element housing is difficult to push or pull when installing or removing the reverse osmosis membrane element, resulting in slow installation, time-consuming and labor-intensive. In addition, the housing is installed slowly using traditional nuts, which is not conducive to rapid identification and positioning installation. When the reverse osmosis membrane element is installed under force, the position of the housing is easily changed. Utility Model Content

[0004] The utility model provides a housing for a high-flux reverse osmosis membrane element to solve the problems of assisting installation of the reverse osmosis membrane element and identifying, positioning and installing the housing proposed in the above background technology.

[0005] The technical solution of the utility model is achieved in this way:

[0006] A housing for a high-flux reverse osmosis membrane element comprises a housing, a threaded joint and a mounting cover, wherein one end of the housing is provided with a threaded joint for threaded connection with the mounting cover, a plurality of connection ends are equidistantly distributed on the periphery of the housing, the connection ends are connected to the interior of the housing, and a power-assisting member is detachably installed in the connection end for power-assisting installation of the reverse osmosis membrane element;

[0007] A bearing plate is attached to the lower side of the shell, and the bearing plate is arc-shaped and fits the outer wall of the shell. Stabilizing parts are provided at both ends of the bearing plate for cooperating with the connecting end to stabilize the shell.

[0008] Furthermore, the power assisting member includes a sealing head and a mounting end. The sealing head is provided with a mounting end below. The mounting end is threadedly mounted in the connecting end. A built-in section is provided inside the mounting end. An elliptical step groove is penetrated through the mounting end. A rolling ball is installed inside the built-in section. An axle rod is inserted into the elliptical step groove for positioning the rolling ball. The rolling ball is rotatably mounted on the axle rod. Nuts are threadedly connected at both ends of the axle rod in the elliptical step groove.

[0009] In the above scheme, the assisting part is installed in the connecting end head, the installing end head is threadedly installed in the connecting end head, an axle rod is inserted into the inside of the elliptical step groove, and the axle rod can move up and down on the elliptical step groove, thereby driving the rolling ball to move up and down. When the reverse osmosis membrane element is inserted and installed, the rolling ball will assist the reverse osmosis membrane element to move, thereby achieving the effect of assisting installation, which is beneficial to the installation and removal of the reverse osmosis membrane element.

[0010] Furthermore, the rotation direction of the rolling ball is kept consistent with the direction in which the reverse osmosis membrane is inserted into the shell, the mounting end and the connecting end are installed in coordination, the bottom end of the mounting end is lower than or equal to the wall thickness of the shell, and the maximum downward movement distance of the rolling ball is greater than the wall thickness of the shell.

[0011] In the above scheme, the rotation direction of the rolling ball remains consistent with the insertion direction of the reverse osmosis membrane, and the inserted reverse osmosis membrane can be displaced along the rotation of the rolling ball, thereby providing an assisting effect. The bottom end of the mounting end is lower than or equal to the wall thickness of the outer shell, so that when the reverse osmosis membrane is inserted, it will not be blocked by the mounting end, and the maximum downward movement distance of the rolling ball is greater than the wall thickness of the outer shell. In this way, when the reverse osmosis membrane is inserted, the rolling ball can be in good contact with the outer wall of the reverse osmosis membrane, providing an assisting effect.

[0012] Furthermore, the stabilizing member includes a clamping joint and a connecting rod, and the clamping joint is symmetrically fixed at both ends of the bearing plate. The clamping joint is in an arc structure for fitting on the outer wall of the connecting end head, and the connecting end head is distributed in a circumferential array in three groups, and the number of the clamping joints and the number of the connecting ends are matched with each other, and any two groups of connecting ends are matched with the clamping joints, and the connecting rod is fixedly connected between the clamping joints, and the arc opening of the clamping joint is covered with anti-slip material.

[0013] In the above scheme, any two of the three groups of connecting ends can cooperate with the card joints, so as to realize the installation of the shell at different angles, and facilitate the opening on the shell to be in different directions. The anti-slip material on the arc-shaped opening of the card joint can strengthen the cooperation between the connecting end and the card joint. When the reverse osmosis membrane element is pushed and pulled to be installed, multiple card joints can provide a strong stabilizing effect, further improving the push-pull installation of the reverse osmosis membrane element. The shell is installed on the bearing plate to provide relative stability to the shell.

[0014] Furthermore, a spring is provided in the built-in area above the rolling ball, and a hexagonal groove is provided on the surface of the sealing head.

[0015] In the above scheme, the setting of the spring can give downward pressure to the rolling ball. When the reverse osmosis membrane element is inserted, the reverse osmosis membrane element squeezes the rolling ball to move, and continuously pushes the reverse osmosis membrane element. The rolling ball will act on the outer wall of the reverse osmosis membrane element to provide assistance. The spring effectively provides pressure for the rolling ball to meet the friction force given to the rolling ball to contact the outer wall of the reverse osmosis membrane element and rotate.

[0016] Furthermore, a sealing gasket is provided below the sealing head. The use of the sealing gasket provides the overall sealing of the device to prevent leakage.

[0017] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0018] 1. Insert the reverse osmosis membrane element from the threaded joint into the housing for installation. The reverse osmosis membrane element that is continuously inserted will be affected by the power-assisting member, which can easily push the reverse osmosis membrane element in or take out the reverse osmosis membrane element, thereby achieving the effect of power-assisting installation, which is beneficial to the installation and removal of the reverse osmosis membrane element;

[0019] 2. The housing is stably placed on the bearing plate. The housing can be well positioned in combination with the stabilizing parts on the bearing plate. When the reverse osmosis membrane element is pushed and pulled, the stabilizing parts can prevent the housing from displacement, further improving the push-pull installation of the reverse osmosis membrane element.

[0020] 3. The shaft can move up and down on the elliptical stepped groove, thereby driving the rolling ball to move up and down. When the reverse osmosis membrane element is inserted and installed, the rolling ball will assist the reverse osmosis membrane element to move, thereby achieving the effect of assisting installation.
