A municipal sewage treatment device

Abstract

This utility model discloses a municipal sewage treatment device, including a body with a filter plate movably connected inside. The filter plate is connected to the body via a positioning mechanism. A water inlet pipe is fixedly connected to the top left side of the body, and a drain pipe is fixedly connected to the bottom right side of the body. By setting up the positioning mechanism, when the filter plate needs to be disassembled for cleaning, the operator only needs to turn the handle counterclockwise to disengage the threaded column from the limiting groove, releasing the fixing of the pull plate. Then, the pull plate is pulled to the right, causing the sliding block to slide in the movable groove via the connecting rod, thereby pulling the positioning column out of the positioning groove, releasing the positioning restriction on the filter plate. Finally, the vertical plate is pulled upwards, allowing the filter plate to detach from the body. The operation is simple, convenient, and quick, greatly facilitating the cleaning of the filter plate.

The top of the two vertical plates on opposite sides is fixedly connected to a baffle.

[0007] Furthermore, the bottom of the baffle is in movable contact with the top of the machine body, a positioning groove is provided on the right side of the baffle, and movable grooves are provided on both the front and rear sides of the top of the machine body, with a sliding block slidably connected to the left side inside the movable groove.

[0008] Furthermore, the top of the sliding block passes through the movable groove and extends to the outside of the movable groove, and a positioning post is fixedly connected to the left side of the sliding block. The left end of the positioning post passes through the positioning groove and extends to the inside of the positioning groove, and the positioning post and the positioning groove are movably engaged.

[0009] Furthermore, a connecting rod is fixedly connected to the lower right side of the sliding block. The right end of the connecting rod passes through the movable groove and the machine body in sequence and extends to the outside of the machine body. The connecting rod is movably connected to the machine body. The right ends of the two connecting rods are fixedly connected to the same pull plate, and the top of the pull plate is provided with a threaded hole.

[0010] Furthermore, a fixing plate is fixedly connected to the upper right side of the machine body, and a limit groove is opened on the top of the fixing plate, and a threaded post is movably engaged inside the limit groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting a positioning mechanism, allows the operator to easily remove the filter plate for cleaning by simply turning the handle counterclockwise to disengage the threaded post from the limiting groove and release the fixing of the pull plate. Then, the operator can pull the pull plate to the right, and the pull plate will drive the sliding block to slide in the movable groove through the connecting rod, thereby pulling the positioning post out of the positioning groove and releasing the positioning restriction on the filter plate. Finally, the operator can pull the vertical plate upward to remove the filter plate from the machine body. The operation is simple, convenient and quick, and greatly facilitates the cleaning of the filter plate.

[0014] 2. When installing the filter plate, place the filter plate inside the machine body, ensuring that the vertical plate and baffle are aligned with the corresponding positions on the machine body. Then, push the pull plate to the left, causing the positioning rod to move to the left and engage in the positioning groove, completing the initial positioning of the filter plate. Next, turn the handle clockwise, causing the threaded post to insert into the limiting groove, thereby limiting the pull plate and making the filter plate installation more stable, effectively preventing the filter plate from shaking or shifting during use.

The bottom of the baffle 302 is in contact with the top of the body 1. A positioning groove 303 is provided on the right side of the baffle 302. Movable grooves 304 are provided on the front and rear sides of the top of the body 1. The inner surface of the groove is hardened to ensure that the sliding block 305 can slide linearly without jamming.

[0027] A sliding block 305 is slidably connected to the left side of the movable groove 304. The top of the sliding block 305 passes through the movable groove 304 and extends to the outside of the movable groove 304. A positioning post 306 is fixedly connected to the left side of the sliding block 305. The left end of the positioning post 306 passes through the positioning groove 303 and extends to the inside of the positioning groove 303. The positioning post 306 and the positioning groove 303 are movably engaged.

[0028] A connecting rod 307 is fixedly connected to the lower right side of the sliding block 305. The connecting rod 307 is made of hollow lightweight alloy material.

[0032] In practical application: During use, sewage enters the machine body 1 through the inlet pipe 4, and then is filtered through the filter plate 2 before being discharged from the drain pipe 5. When it is necessary to disassemble the filter plate 2 for cleaning, the operator only needs to turn the handle 313 counterclockwise to disengage the threaded column 312 from the limiting groove 311, thereby releasing the fixation of the pull plate 308. Then, pull the pull plate 308 to the right. The pull plate 308 drives the sliding block 305 to slide in the movable groove 304 through the connecting rod 307, thereby causing the positioning column 306 to be pulled out from the positioning groove 303, releasing the positioning restriction on the filter plate 2. Then, pull the vertical plate 301 upward to detach the filter plate 2 from the machine body 1. The operation is simple, convenient and quick to disassemble the filter plate 2, greatly facilitating the cleaning of the filter plate 2.
