[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] The FRP membrane housing is mainly used for loading reverse osmosis membrane elements to improve the use efficiency of the membrane elements. The FRP membrane housing is a high-pressure resistant structure specifically applied to the disk tube reverse osmosis equipment. In the prior art, when installing the side interface of the FRP membrane housing, the FRP membrane housing is prone to rotation and offset, resulting in time-consuming and laborious installation operations of the FRP membrane housing, which is rather inconvenient. Some embodiments of the present invention will be described below with reference to the accompanying drawings to provide an FRP membrane housing that is not prone to rotation and offset.

[0023] Embodiment 1:

[0024] In order to prevent the FRP membrane housing from rotating and offsetting during the installation of its side interface, as shown in Figure 1 、 Figure 2 and Figure 3 , a non-rotatable and non-offset FRP membrane housing is proposed. By setting the FRP membrane housing body 1 as the device main body, two fixing mechanisms 2 are arranged on the outer side of the FRP membrane housing body 1. The two fixing mechanisms 2 are used to effectively fix the FRP membrane housing body 1, and a locking mechanism 3 is arranged between the two fixing mechanisms 2. The locking mechanism 3 is used to further lock the fixing mechanism 2.

[0025] In order to improve the stability of the fiberglass membrane housing during the installation process, a fixing mechanism 2 is proposed. By setting a fixing seat 201, a through groove 202 is opened in the fixing seat 201, and a bidirectional threaded rod 203 is rotatably connected in the through groove 202. Both side walls in the through groove 202 are provided with sliding grooves. Two vertical rods 204 are respectively threadedly connected to the two threads of the bidirectional threaded rod 203. Sliders are fixedly connected to both sides of the two vertical rods 204. Fixing blocks 205 are fixedly connected to the opposite sides of the two vertical rods 204. A plurality of insertion rods 208 are installed on the outer side of the fiberglass membrane housing body 1. Abnormal-shaped rings 206 are clamped on the plurality of insertion rods 208. Anti-slip pads 207 are installed on the sides of the plurality of abnormal-shaped rings 206 close to the fiberglass membrane housing body 1. The plurality of sliders are evenly distributed in the plurality of sliding grooves. Tooth grooves are opened on the sides of the plurality of fixing blocks 205 close to the fiberglass membrane housing body 1. Two groups of tooth blocks are fixedly connected to the plurality of abnormal-shaped rings 206. The tooth grooves on the two fixing blocks 205 in the same fixing seat 201 are respectively meshed and connected with the two groups of tooth blocks on the two adjacent abnormal-shaped rings 206. By fixing the positions of the two bidirectional threaded rods 203 through the two fixing seats 201, adjusting and moving the plurality of vertical rods 204 through the two bidirectional threaded rods 203, clamping the positions of the plurality of abnormal-shaped rings 206 through the plurality of insertion rods 208, and synchronously rotating the two bidirectional threaded rods 203 to make the two groups of vertical rods 204 approach each other, the tooth grooves on the two groups of fixing blocks 205 can be fitted and connected with the tooth blocks on the plurality of abnormal-shaped rings 206, so as to connect and fix two adjacent abnormal-shaped rings 206, so that the fiberglass membrane housing can be stably fixed, not easily rotate and shift during the installation process, and the simplicity of the device is improved.

[0026] Embodiment Two:

[0027] On the basis of Embodiment One, the technical solution proposed in Embodiment One is used to solve the problem that when installing the side interface of the fiberglass membrane housing in the prior art, the fiberglass membrane housing is prone to rotation and offset, resulting in time-consuming and laborious installation operations of the fiberglass membrane housing and being rather inconvenient. However, after the fiberglass membrane housing is fixed, in order to prevent the bidirectional threaded rod 203 from rotating by itself and thus affecting the fixing effect, it should be further locked.

[0028] To ensure the fixing effect of the fiberglass membrane housing, in combination with Figure 1 and Figure 3 as well as Figure 4As shown in the figure, a locking mechanism 3 is proposed. By rotatably connecting a locking wheel 301 to one side of two fixed seats 201, a connecting plate 302 is fixedly connected between the two fixed seats 201. On one side of the connecting plate 302, adjustment grooves 303 are symmetrically formed. On one side of each of the two adjustment grooves 303, a connecting groove 304 is communicated. Springs 305 are fixedly connected in each of the two connecting grooves 304. Connecting blocks 306 are slidably connected in each of the two connecting grooves 304. On one side of each of the two connecting blocks 306, a locking block 307 is fixedly connected. The two locking wheels 301 are respectively connected to one end of two bidirectional threaded rods 203. On one side of each of the two locking blocks 307, a locking groove 308 is formed. The two locking blocks 307 can be meshed and connected to the two locking wheels 301 through the locking grooves 308. One end of each of the two springs 305 is fixedly connected to one side of each of the two connecting blocks 306. The position of the connecting plate 302 is fixed by the two fixed seats 201. By synchronously pulling the two locking blocks 307, the two connecting blocks 306 slide in the connecting grooves 304, thereby squeezing the two springs 305. At this time, the two bidirectional threaded rods 203 are adjusted and rotated by the two locking wheels 301. After the fiberglass membrane shell is fixed, the staff cancels the acting force on the two locking blocks 307 at this time, so that the two locking blocks 307 are subjected to the rebounding action of the two springs 305, enabling the two locking blocks 307 to fix the two locking wheels 301, further improving the stability of the fiberglass membrane shell during the installation process.

[0029] It should be noted that the term "comprise", "include" or any other variant thereof is intended to cover a non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
