Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment accessories, in particular to a corrosion-resistant inner inlet grid filter plate. Background Art

[0002] The in-flow mesh screen dirt remover is a highly efficient fine screen dirt removal device that combines both dirt interception and dirt removal. It is suitable for large, medium, and small pumping stations as a fine screen to intercept and remove floating objects in the water, such as weeds, paper scraps, cigarette butts, melon seeds, fibers, hair, etc. This model has a high dirt capture rate and can effectively implement subsequent treatment processes. The in-flow mesh screen dirt remover mainly consists of a drive unit, a frame, a traction chain, a filter screen, a flushing system, and an electronic control system. The drive motor is installed on the main shaft in the forward direction of the frame. Driven by the transmission chain, the filter screens on both sides extract the dirt trapped within their length from bottom to top. When they reach the top, most of the solid matter falls by gravity into the slag trough for discharge.

[0003] At present, the filter panels in the prior art are usually connected in a hinged manner. When the surface of the filter panel is damaged or needs to be replaced after long-term use, the staff needs to disassemble and replace the filter panel as a whole. When the staff disassembles the filter panel, it is necessary to remove the hinge structure, and then take out a new filter panel and fix it again through the hinge structure. The disassembly and installation process of the filter panel is relatively cumbersome, which not only increases the labor intensity of the staff, but also increases the time for replacing the filter panel, affecting the convenience of the filter panel during use. Utility Model Content

[0023] See also Figure 1-4 The utility model provides a technical solution: a corrosion-resistant inner inlet flow grille filter screen, comprising a screen body 1 and a splicing fixed installation device. Two trapezoidal blocks 2 are fixedly connected to the left side of the screen body 1, and two trapezoidal slots 3 are provided on the right side of the screen body 1. The two trapezoidal blocks 2 are respectively slidably connected to the inside of the two trapezoidal slots 3. Two fixed sliders 4 are fixedly connected to the top of the screen body 1, and positioning grooves 5 are provided on the surfaces of the two fixed sliders 4. Two connecting slides 6 are provided at the bottom of the screen body 1, and the two fixed sliders 4 are respectively slidably connected to the inside of the two connecting slides 6.

[0024] When the staff installs the mesh panel bodies 1 on the left and right sides, they only need to slide the two trapezoidal blocks 2 on the surface of the right mesh panel body 1 into the two trapezoidal slots 3 on the surface of the left mesh panel body 1 to complete the installation. The mesh panel bodies 1 on the left and right sides can be installed and fixed through the clamping action between the two trapezoidal blocks 2 and the two trapezoidal slots 3. The two trapezoidal blocks 2 are trapezoidal structures, which can increase the stability of the connection between the two mesh panel bodies 1. The mesh panel body 1 is a polyethylene injection molded part. The mesh panel body 1 uses ultra-high molecular polyethylene as the material. Its surface is smooth and has sufficient strength and rigidity. It is not easy to produce hair and floc adsorption, and the mesh panel body 1 will not be corroded by the action of sewage, thereby making the grille filter plate corrosion-resistant and extending the service life of the grille filter plate.

[0025] The splicing fixed installation device includes two fixed blocks 7, two push-pull protrusions 8 and a spring 9. The two fixed blocks 7 are both slidably connected to the inside of the mesh plate body 1. The two fixed blocks 7 are symmetrically arranged. The two push-pull protrusions 8 are respectively fixedly connected to the surfaces of the two fixed blocks 7. The spring 9 is fixedly connected to the inner side of the two fixed blocks 7. The opposite ends of the two fixed blocks 7 are each provided with an inclined surface 10. The opposite ends of the two fixed blocks 7 are respectively slidably clamped in the inside of the two positioning grooves 5.

[0026] When the staff installs the two upper and lower mesh panel bodies 1, the staff only needs to slide the lower mesh panel body 1 upward, and the lower mesh panel body 1 slides and drives the two fixed sliders 4 on the top to slide into the two connecting slide grooves 6 on the surface of the upper mesh panel body 1. At this time, the two fixed sliders 4 slide upward and squeeze the inclined surfaces 10 of the two fixed blocks 7, and make the two fixed blocks 7 slide relative to each other. The two fixed blocks 7 slide relative to each other to squeeze the spring 9, and the spring 9 gives the two fixed blocks 7 a reverse force. After the two fixed sliders 4 completely slide into the interior of the two connecting slide grooves 6, the spring 9 releases the elastic force and pushes the two fixed blocks 7 to slide in the opposite direction. The two fixed blocks 7 slide in the opposite direction and are stuck in the inside of the two positioning grooves 5, and then the two fixed sliders 4 can be fixedly installed on the bottom of the upper mesh panel body 1 through the two fixed blocks 7, and the upper and lower mesh panel bodies 1 can be fixedly installed together.

[0027] When the staff needs to remove the mesh panel body 1, the staff slides the two push-pull protrusions 8, and the two push-pull protrusions 8 slide and drive the two fixed blocks 7 to slide relative to the extrusion springs 9. The two fixed blocks 7 slide and slide out of the two positioning grooves 5, thereby releasing the fixing effect on the two fixed sliders 4. The staff slides the mesh panel body 1 and drives the two fixed sliders 4 to slide out of the two connecting slide grooves 6 to complete the disassembly. In this way, it is convenient for the staff to disassemble and assemble the mesh panel body 1, which simplifies the process of disassembly and installation of the mesh panel body 1, not only reduces the labor intensity of the staff, but also reduces the time for replacing the mesh panel body 1, and improves the convenience of the mesh panel body 1 during use.

[0028] Working principle: When the staff installs the left and right sides of the mesh panel body 1, they only need to slide the two trapezoidal blocks 2 on the surface of the right mesh panel body 1 into the two trapezoidal slots 3 on the surface of the left mesh panel body 1 to complete the installation. When the staff installs the upper and lower mesh panel bodies 1, they only need to slide the lower mesh panel body 1 upward, and the lower mesh panel body 1 slides and drives the two fixed sliders 4 on the top to slide into the two connecting slots 6 on the surface of the upper mesh panel body 1. At this time, the two fixed sliders 4 slide upward and squeeze Press the inclined surfaces 10 of the two fixed blocks 7 and make the two fixed blocks 7 slide relative to each other. The two fixed blocks 7 slide relative to each other to squeeze the spring 9. The spring 9 gives the two fixed blocks 7 a reverse force. When the two fixed sliders 4 completely slide into the interior of the two connecting slides 6, the spring 9 releases the elastic force and pushes the two fixed blocks 7 to slide in the opposite direction. The two fixed blocks 7 slide in the opposite direction and are stuck into the interior of the two positioning grooves 5. Then, the two fixed sliders 4 can be fixedly installed on the bottom of the upper mesh plate body 1 through the two fixed blocks 7, and the upper and lower mesh plate bodies 1 can be fixedly installed together.

[0029] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
