Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a mud discharge device for sewage treatment. Background Art

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering, etc., and is increasingly entering the daily lives of ordinary people.

[0003] According to application number 202021700634.5, a mud discharge device for sewage treatment includes a box body, a mud scraper, a threaded rod and a baffle. Two mud discharge grooves are symmetrically opened at the bottom of the box body, and two sliding slots are provided between the two mud discharge grooves. These two sliding slots are also opened at the bottom of the box body: a baffle is slidably installed in each of the two sliding slots; two sealing plates are slidably installed in the box body; a threaded rod is installed in each of the two sealing plates.

[0004] This device connects two sealing plates, which isolate the sludge at the bottom of the tank from the water inside. This prevents the sludge from mixing with the water inside the tank during sludge removal, potentially contaminating the treated sewage. However, the filter plates in this device are fixed and cannot be removed. Over time, sludge can accumulate in the filter plate pores, affecting subsequent sewage treatment. Utility Model Content

[0005] The purpose of the utility model is to provide a sludge discharge device for sewage treatment to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a sludge discharge device for sewage treatment, comprising a base, a box body fixedly connected to the top of the base, a water outlet pipe fixedly connected to the right side of the front of the box body near the bottom, a lifting mechanism provided on the top of the base near the back, and a processing mechanism provided at the bottom of the lifting mechanism;

[0007] The processing mechanism includes a rectangular frame, which is fixedly connected to the bottom of the lifting mechanism. A rectangular limiting ring is fixedly connected to the inner wall of the rectangular frame near the back. A filter plate is slidably connected up and down in the rectangular frame. Cavities are symmetrically opened on the left and right sides inside the rectangular frame. A slide plate is slidably connected left and right in the cavity. Slant rods are equidistantly arranged on the left and right sides of the inner wall of the rectangular frame. Guide rods are symmetrically fixedly connected to the front and back on the left and right sides inside the cavity. Springs are sleeved on the surface of the guide rods between the cavity and the slide plate. A T-shaped block is fixedly connected to the side of the slide plate away from the slant rod. Slide frames are symmetrically arranged on the left and right at the top of the rectangular frame. Limiting rings are fixedly connected to the surfaces of the slide frames. Fixing holes corresponding to the slant rods are opened on the left and right sides of the filter plate.

[0008] Preferably, holes matching the slant rods are opened on the left and right sides of the inner wall of the rectangular frame, and the slant rods penetrate and are slidably connected through the holes. The other end of the slant rod is fixedly connected to the other side of the slide plate. Through holes matching the guide rods are opened on the front, back, left, and right of the surface of the slide plate, and the slide plate is slidably connected to the surface of the guide rods through the holes.

[0009] Preferably, one end of the spring is fixedly connected to the inner wall of the cavity away from the slide plate, and the other end of the spring is fixedly connected to the side of the slide plate away from the slant rod.

[0010] Preferably, the left side of the T-shaped block is bevel-shaped, and both ends of the slide frame are bevel-shaped.

[0011] Preferably, the lifting mechanism includes a fixed frame, which is fixedly connected to the top of the base near the back. A screw rod is rotatably connected to the top of the base near the back. A nut plate is threadedly connected to the surface of the screw rod. A motor is fixedly connected to the top of the fixed frame. Limiting rods are symmetrically opened on the left and right at the top inside the fixed frame. A lifting frame is fixedly connected to the top of the nut plate near the front.

[0012] Preferably, a hole matching the output shaft of the motor is opened at the top of the fixed frame, and the output shaft of the motor penetrates and is rotatably connected through the hole. The output end of the motor is fixedly connected to the top end of the screw rod. The rectangular frame is fixedly connected to the other end of the lifting frame.

[0013] Preferably, through holes matching the limiting rods are opened on the left and right sides at the top of the nut plate, and the nut plate is slidably connected to the surface of the limiting rods through the holes. The bottom ends of the limiting rods are fixedly connected to the top of the base near the back. The two limiting rods limit the nut plate, so that the nut plate can only move up and down as the screw rod rotates.

[0014] Compared with the prior art, the present utility model provides a sludge discharging device X for sewage treatment, which has the following beneficial effects:

[0015] The sludge discharging device for sewage treatment pours sewage into the box through a treatment mechanism, and then pours a flocculant (such as polyaluminum chloride, polyacrylamide, etc.) into the box to make the sludge particles in the sewage in the box gather together to form larger flocs. Then, the filter plate is moved upward, and the filter plate drives the flocculent sludge to move upward, so as to treat the sludge on the filter plate. When the filter plate needs to be replaced, press down the sliding frame to make the sliding frame press down the T-shaped block, so that the two T-shaped blocks move towards each other, thereby making the sliding plate drive the inclined rod to move towards each other and drive out of the fixing hole. Then, the old filter plate is drawn out of the rectangular frame, and the new filter plate is slid into the rectangular frame. At this time, when the filter plate moves downward, it will squeeze the inclined rod. When the bottom of the filter plate completely fits the top of the rectangular limit ring, the inclined rod will drive out of the fixing hole by the elastic force of the spring to fix the filter plate in the rectangular frame. This process can replace the filter plate so that the filter plate will not affect the filtration efficiency due to long-term use.

[0016] For the sludge discharging device for sewage treatment, after the sludge in the sewage forms flocs through the lifting mechanism, start the motor to make the screw rotate. The rotation of the screw will make the screw plate move upward, thereby driving the lifting frame to move upward, and further driving the rectangular frame and the filter plate to move upward, so that the filter plate drives the flocculent sludge to move upward, which can more conveniently treat the flocs.

[0029] The processing mechanism 5 includes a rectangular frame 51, the rectangular frame 51 is fixedly connected to the bottom of the lifting mechanism 4, a rectangular limiting ring 52 is fixedly connected to the inner wall of the rectangular frame 51 near the back, a filter plate 53 is slidably connected up and down in the rectangular frame 51, cavities 54 are symmetrically opened on the left and right sides in the rectangular frame 51, a sliding plate 56 is slidably connected left and right in the cavities 54, inclined rods 55 are equidistantly arranged on the left and right sides of the inner wall of the rectangular frame 51, guide rods 57 are fixedly connected symmetrically in the front and back on the left and right sides in the cavities 54, a spring 58 is sleeved on the surface of the guide rod 57 between the cavity 54 and the sliding plate 56, a T-shaped block 59 is fixedly connected to the side of the sliding plate 56 away from the inclined rod 55, sliding brackets 511 are symmetrically arranged on the left and right at the top of the rectangular frame 51, a limiting ring 512 is fixedly connected to the surface of the sliding bracket 511, and fixing holes 513 corresponding to the inclined rods 55 are opened on the left and right sides of the filter plate 53.

[0030] Holes matching the inclined rods 55 are opened on the left and right sides of the inner wall of the rectangular frame 51, and the surface of the inclined rod 55 penetrates and is slidably connected in the holes, the other end of the inclined rod 55 is fixedly connected to the other side of the sliding plate 56, holes matching the guide rods 57 are opened in the front, back, left and right on the surface of the sliding plate 56, and the sliding plate 56 is slidably connected to the surface of the guide rod 57 through the holes.

[0031] One end of the spring 58 is fixedly connected to the inner wall of the cavity 54 away from the sliding plate 56, and the other end of the spring 58 is fixedly connected to the side of the sliding plate 56 away from the inclined rod 55.

[0032] The left side of the T-shaped block 59 is in an inclined shape, and both ends of the sliding bracket 511 are in an inclined shape.

[0033] For Embodiment 2, please refer to Figures 1-3 and on the basis of Embodiment 1, the lifting mechanism 4 is further obtained.

[0034] The lifting mechanism 4 includes a fixed frame 41, the fixed frame 41 is fixedly connected to the top of the base 1 near the back, a screw rod 42 is rotatably connected to the top of the base 1 near the back, a screw plate 44 is threadedly connected to the surface of the screw rod 42, a motor 43 is fixedly connected to the top of the fixed frame 41, limiting rods 45 are symmetrically opened on the left and right at the top inside the fixed frame 41, and a lifting frame 46 is fixedly connected to the top of the screw plate 44 near the front.

[0035] A hole matching the output shaft of the motor 43 is opened at the top of the fixed frame 41, and the surface of the output shaft of the motor 43 penetrates and is rotatably connected in the hole, the output end of the motor 43 is fixedly connected to the top end of the screw rod 42, and the rectangular frame 51 is fixedly connected to the other end of the lifting frame 46.

[0036] On the left and right sides of the top of the screw plate 44, there are holes matching the limiting rods 45, and the screw plate 44 is slidably connected to the surface of the limiting rods 45 through the holes. The bottom ends of the limiting rods 45 are fixedly connected to the top of the base 1 near the back.

[0037] During the actual operation process, when this device is in use, pour the sewage into the box body 2, and then pour flocculants (such as polyaluminum chloride, polyacrylamide, etc.) into the box body 2 to make the sludge particles in the sewage in the box body 2 gather together to form larger flocs.

Then pull out the old filter plate 53 from the rectangular frame 51, and slide the new filter plate 53 into the rectangular frame 51. At this time, when the filter plate 53 moves downward, it will squeeze the inclined rod 55. When the bottom of the filter plate 53 completely fits the top of the rectangular limiting ring 52, the inclined rod 55 will drive out of the fixing hole 513 by the elastic force of the spring 58, and fix the filter plate 53 in the rectangular frame 51. This process can replace the filter plate 53, so that the filter plate 53 will not affect the filtration efficiency due to long-term use.

[0038] After the sludge in the sewage forms flocs, start the motor 43 to rotate the screw 42. The rotation of the screw 42 will make the screw plate 44 move upward, thereby driving the lifting frame 46 to move upward, and further driving the rectangular frame 51 and the filter plate 53 to move upward, so that the filter plate 53 drives the flocculent sludge upward, which can more conveniently treat the flocs.
