Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an interception device for wastewater treatment. Background Technology

[0002] In wastewater treatment, wastewater often contains various solid impurities, suspended solids, and larger particulate pollutants. If these substances are not effectively intercepted beforehand, they can cause blockages, wear, or increased loads on pumps, pipes, and treatment equipment in subsequent processes, affecting wastewater treatment efficiency and equipment lifespan. Existing interception devices suffer from problems such as frequent cleaning of clogged screens, low automation leading to high manual maintenance costs, varying interception effectiveness for pollutants of different particle sizes, and unreasonable structural design affecting water flow. Furthermore, some devices are ill-suited for treating complex water qualities and large volumes of wastewater.

[0003] An existing wastewater treatment interception device uses a filter screen to intercept solid impurities. After a period of use, the filter screen is manually removed for cleaning or replacement. However, in actual use, the solid impurities accumulate and bury the opening of the filter screen. When removing the filter screen, it is necessary to use hands or tools to pry open the impurities and take out the filter screen, which is quite troublesome. Therefore, we propose an interception device for wastewater treatment. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an interception device for sewage treatment, which lifts the filter screen by means of air pressure transmission through a pressure plate and a top plate, so as to facilitate cleaning or replacement.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A wastewater treatment interception device includes a filtration mechanism, an interception mechanism is movably installed at the inner end of the filtration mechanism, and a transmission mechanism is fixedly installed at the lower end of the interception mechanism.

[0007] The transmission mechanism includes a movable box. A limiting plate is fixedly installed on the upper inner side of the movable box. A partition is movably installed on the upper end of the movable box. A notch is provided on the upper side of the partition. A conduit is connected to the lower end of the movable box. A top plate is provided at the end of the conduit. A pressure plate is provided on the upper side of the starting end of the conduit. A top rod is fixedly connected to the lower end of the top plate. A piston is fixedly connected to the lower end of the top rod. A pressure rod is fixedly connected to the lower end of the pressure plate. A piston is fixedly connected to the lower end of the pressure rod. A second piston is fixedly connected to the inner end of the openings at both ends of the conduit. A limiting plate is provided at the inner end of the openings at both ends of the conduit. By setting the pressure rod to compress the piston second, the gas in the conduit moves towards the top rod, lifting the top rod and the top plate, causing the interception basket to rise, making it easy to remove for cleaning or replacement, thus improving the convenience of using the device.

[0008] Furthermore, the interception mechanism includes an interception basket, with a filter screen at the inner end of the interception basket and a slider at the outer side of the interception basket. By setting the filter screen to intercept solid particles in the wastewater, problems such as blockage, wear, or increased load on water pumps, pipes, and treatment equipment in subsequent treatment processes are avoided, thereby improving the safety and stability of wastewater treatment.

[0009] Furthermore, the filtration mechanism includes a filter box, with a sliding groove provided on the inner side of the filter box. A cover plate is movably installed on the upper end of the filter box, and a filter slit is provided on the upper end of the front end of the cover plate. By setting the filter slit, the sewage is initially filtered to remove larger solid impurities, thus preventing larger impurities from entering the interception basket and occupying a lot of space, which would cause the interception basket to need to be cleaned and replaced frequently, thereby improving the convenience of using the device.

[0010] Furthermore, the interception basket is movably installed in the middle of the inner end of the filter box, and the slider is connected to the slide groove. By setting the slider, the interception basket can move in a directional manner along the direction of the slide groove, preventing the interception basket from deviating during movement and improving the stability of the device during use.

[0011] Furthermore, a top plate is movably connected to the lower end of the interception basket, and the contact area between the interception basket and the top plate is a solid structure.

[0012] Furthermore, both piston one and piston two are sealed to the conduit.

[0013] Furthermore, the push rod and piston one, as well as the pressure rod and piston two, can all move up and down along the vertical region of the guide tube.

[0014] Furthermore, there are two pairs of limiting plates, both pairs of which are rectangular structures with one end of the rectangular face fixedly connected to the inner wall of the conduit.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. By setting up a pressure rod to compress the piston, the gas in the duct moves towards the top rod, lifting the top rod and the top plate to raise the interception basket, making it easy to remove for cleaning or replacement, thus improving the convenience of the device. By setting up a filter screen to intercept solid particles in the wastewater, it avoids problems such as blockage, wear or increased load on the pumps, pipes and treatment equipment in the subsequent treatment process, thus improving the safety and stability of the sewage treatment work.

[0017] 2. By setting filter gaps, the wastewater is initially filtered to remove larger solid impurities, preventing them from entering the interception basket and occupying a lot of space, thus avoiding the need for frequent cleaning and replacement of the interception basket. This improves the convenience of the device during use. By setting a slider, the interception basket can move in a directional manner along the chute, preventing the interception basket from deviating during movement and improving the stability of the device during use.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0026] Reference Figure 1-5 As shown, a wastewater treatment interception device is provided in a preferred embodiment of the present invention, including a filter mechanism 1, an interception mechanism 2 is movably installed at the inner end of the filter mechanism 1, and a transmission mechanism 3 is fixedly installed at the lower end of the interception mechanism 2.

[0027] The transmission mechanism 3 includes a movable box 301. A limit plate 302 is fixedly installed on the upper inner side of the movable box 301. A partition 303 is movably installed on the upper end of the movable box 301. A notch 304 is provided on the upper side of the partition 303. A guide tube 305 is connected to the lower end of the movable box 301. A top plate 306 is provided at the end of the guide tube 305. A pressure plate 307 is provided on the upper side of the starting end of the guide tube 305. A push rod 308 is fixedly connected to the lower end of the top plate 306. A piston 309 is fixedly connected to the lower end of the push rod 308. The pressure plate 307... A pressure rod 310 is fixedly connected to the lower end of the conduit 305, and a piston 311 is fixedly connected to the lower end of the pressure rod 310. Limiting plates 312 are installed at the inner ends of the openings at both ends of the conduit 305. There are two pairs of limiting plates 312, both of which are rectangular in structure, with one end of the rectangular face fixedly connected to the inner wall of the conduit 305. By setting the limiting plates 312 at the openings of the conduit 305, excessive displacement of the piston 309 or piston 311 from the conduit 305 is prevented, thus improving the protective performance and stability of the device during use. Rod 308, piston 309, pressure rod 310, and piston 311 can all move vertically along the vertical region of guide tube 305. By enabling these components to move vertically along the vertical region of guide tube 305, the vertical pressure received by pressure rod 310 can be converted into an upward supporting force from the top rod 308. This force, transmitted through air, causes the interception basket 201 to bulge upwards for easy disassembly, improving the convenience of use. Piston 309 and... Both pistons 311 and 309 are sealed to the conduit 305. By ensuring that both pistons 309 and 311 are sealed to the conduit 305, the gas volume inside the conduit 305 remains constant, facilitating the transmission of force through gas movement and improving the ease of use of the device. By using the pressure rod 310 to compress piston 311, the gas inside the conduit 305 moves towards the push rod 308, lifting the push rod 308 and the top plate 306, causing the interception basket 201 to rise, making it easy to remove for cleaning or replacement, further improving the ease of use of the device.

[0028] Reference Figure 1-3As shown, the interception mechanism 2 includes an interception basket 201, with a filter screen 202 installed at the inner end of the interception basket 201 and a slider 203 installed on the outer side of the interception basket 201. By setting the filter screen 202 to intercept solid particles in the wastewater, problems such as blockage, wear or increased load on the water pumps, pipes and treatment equipment in the subsequent treatment process are avoided, thereby improving the safety and stability of the sewage treatment work.

[0029] Reference Figure 1-3 As shown, the filtration mechanism 1 includes a filter box 101. A sliding groove 102 is provided on the inner side of the filter box 101. A cover plate 103 is movably installed on the upper end of the filter box 101. A filter slit 104 is provided at the upper end of the front end of the cover plate 103. By setting the filter slit 104, the sewage is initially filtered to remove larger solid impurities, thus preventing larger impurities from entering the interception basket 201 and occupying a lot of space, which would cause the interception basket 201 to need to be cleaned and replaced frequently. This improves the convenience of using the device.

[0030] Reference Figure 2-5 As shown, the lower end of the interception basket 201 is movably connected to the top plate 306. The contact area between the interception basket 201 and the top plate 306 is a solid structure. By setting the contact area between the interception basket 201 and the top plate 306 to be a solid structure, the interception basket 201 is sufficient to withstand the supporting force provided by the top plate 306, making the interception basket 201 less prone to deformation or damage, improving the overall strength of the device during use, and making the device more stable. The interception basket 201 is movably installed in the middle of the inner end of the filter box 101. The slider 203 is connected to the slide groove 102. By setting the slider 203, the interception basket 201 can move directionally along the direction of the slide groove 102, preventing the interception basket 201 from deviating during movement, and improving the stability of the device during use.

[0031] Specific implementation process: When it is necessary to disassemble the interception basket 201 for cleaning or replacement, the operator first places their hand on the pressure plate 307 and applies downward pressure to it. Under this pressure, the pressure plate 307 moves downward, causing the connected pressure rod 310 to move downward as well. The downward movement of the pressure rod 310 pushes the piston 311 downward within the conduit 305, compressing the air inside. As the air in the conduit 305 is compressed, the air pressure increases, pushing the top rod 308 upward. The top rod 308 then drives the piston 309 and the top plate 306 to move upward synchronously. During the upward movement of the top plate 306, it contacts the interception basket 201 and pushes it upward until the interception basket 201 reaches a position suitable for disassembly. At this point, the operator can disassemble, clean, or replace the interception basket 201. This device utilizes the principle of gas pressure. Initially, the conduit 305 is filled with air, and the pistons 309 and 311 are in a balanced position. When the pressure plate 307 is pressed down, the pressure rod 310 drives the piston 311 to move downwards in a straight line within the conduit 305. The air inside the conduit 305 is compressed. According to the relationship between gas pressure and volume, the gas volume decreases and the pressure increases in the confined space. The increased air pressure generates an upward thrust, pushing the piston 309 and the push rod 308 upwards. The push rod 308 then pushes the top plate 306 to lift the interception basket 201 upwards. Through this process, the pressure exerted by the human on the pressure plate 307 is converted into an upward thrust from the top plate 306 onto the interception basket 201, enabling the interception basket 201 to rise. This facilitates its disassembly and improves the convenience and efficiency of cleaning and maintaining the interception basket 201 during wastewater treatment.
