Description

Technical Field

[0001] This invention relates to the field of sludge treatment technology, and more specifically to a sludge treatment device for biotechnology. Background Technology

[0002] Biotechnology refers to the use of advanced scientific and technological means, based on modern life sciences and combined with the scientific principles of other basic sciences, to modify organisms or process biological raw materials according to a pre-designed plan, in order to produce products needed by mankind or achieve certain purposes. With the increasing volume of sewage treatment year by year, sludge treatment has become an important link. At present, the sludge can only be roughly processed and crushed during the treatment and separation process. Sludge accumulates at the bottom of rivers for a long time, and a large amount of garbage is attached to it. If it is not treated, it will lead to environmental pollution. Therefore, we have proposed a sludge treatment device using biotechnology. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a sludge treatment device for biotechnology, including a treatment box, a support leg at the bottom of the treatment box, a material receiving door at the top of the treatment box, a feeding rack at the top left side of the treatment box, a motor one at the left side of the treatment box, a motor two at the right side of the treatment box, and a separation mechanism inside the treatment box. The separation mechanism includes a disc frame, a separation frame, a sealing door, and a storage tube. The disc frame is fixedly connected to the inner wall of the processing box, and the separation frame is rotatably connected to the disc frame via bearings. A material retrieval door is provided at the top of the processing box, and a sealing door is provided at the top of the storage tube to facilitate cleaning of the waste inside the sludge. A discharge frame is connected to the bottom of the processing box to facilitate the processing of the treated sludge. The left side of the rotating rod is fixedly connected to the output end of motor one, and the right side of the storage tube is fixedly connected to the output end of motor two. The storage tube is fixedly connected to the separation frame, and a sealing door is hinged to the top of the storage tube. The outer surface of the storage tube is rotatably connected to the inner wall of the processing box via a rotating shaft. The storage tube passes through the processing box and is fixedly connected to the output end of motor two. Multiple separation holes are opened on the outer surface of the separation frame.

[0004] Furthermore, the separation frame includes a rotating rod, a sludge squeezing block, a circular ring plate, a turbine blade, and a waste cleaning mechanism. The left side of the rotating rod is fixedly connected to the output end of the first motor, and the outer surface of the rotating rod is fixedly connected to the turbine blade. The sludge squeezing block is fixedly connected to the outer surface of the rotating rod via a connecting rod. The end of the rotating rod away from the first motor is rotatably connected to the inner wall of the storage pipe via a bearing. A turbine blade is provided on the surface of the rotating rod to guide the sludge in the disc frame to move towards one end of the storage pipe, thereby increasing the sludge processing efficiency. The outer surface of the sludge squeezing block is fixedly connected to the circular ring plate, and a waste cleaning mechanism is provided on the outer surface of the sludge squeezing block. The sludge compression block contacts the inner wall of the separation frame.

[0005] Furthermore, the left side of the separating frame is connected to the interior of the disc frame, the right side of the separating frame is connected to the interior of the storage tube, and the top of the disc frame is connected to the bottom of the feeding frame.

[0006] Furthermore, the waste cleaning mechanism includes a groove, a bottom plate, and a rack plate. The top of the sludge squeezing block is provided with a groove, and the bottom plate is fixedly connected to the inner wall of the groove. A groove is provided on the surface of the sludge squeezing block to limit the bottom plate and increase the working efficiency of the rack plate. The top of the bottom plate is fixedly connected to the rack plate. The outer surface of the rack plate is in contact with the inner wall of the separator.

[0007] Furthermore, the processing box includes an arc-shaped slider, a pushing mechanism, a discharge rack, a scraper, and a discharge hole. The discharge rack is connected to the bottom of the processing box, and the scraper is fixedly connected to the inner wall of the discharge rack. The scraper has a discharge hole. The discharge rack is set at the bottom of the processing box to discharge the processed sludge. The scraper is set inside the discharge rack to clean the surface of the separation rack, so as to prevent the sludge from sticking to the surface of the separation rack when it is discharged into the separation rack through the separation hole, thus affecting the separation efficiency. The arc-shaped slider is fixedly connected to the inner wall of the processing box, and the pushing mechanism is set at the top of the inner wall of the discharge rack. The top of the scraper contacts the outer surface of the separator.

[0008] Furthermore, the discharge holes are located at the front and rear ends of the scraper, and the discharge rack extends out of the bottom outer end of the processing box.

[0009] Furthermore, the pushing mechanism includes an arc-shaped movable plate, a slider, and an extrusion plate. The arc-shaped movable plate is movably connected to the outer surface of the arc-shaped slider via a rotating shaft. Multiple sliders are provided on the top of the arc-shaped movable plate to contact the inner wall of the separation hole, so that the arc-shaped movable plate can reciprocate through the elasticity of the extrusion plate. The end of the arc-shaped movable plate near the unloading frame is fixedly connected to the extrusion plate, and multiple sliders are fixedly connected to the top of the arc-shaped movable plate. The arc-shaped movable plate is located above the unloading hole.

[0010] Furthermore, the outer surface of the slider is adapted to the inner wall of the separation hole, and the arc-shaped movable plate is adapted to the inner wall of the unloading rack.

[0011] Furthermore, the turbine blades are fixed to the rotating rod and extend into the interior of the disc frame, and the sludge extrusion block is arc-shaped to fit the inner wall of the separation frame.

[0012] The beneficial effects of this invention are as follows: When this invention is used, sludge is fed into the disc frame through the feeding rack; when the rotating rod rotates, the turbine blades push the sludge in the disc frame into the separation frame; when the separation frame rotates, the separation holes throw the sludge out of the separation frame, thus achieving separation. The garbage in the sludge accumulates inside the separation frame and is separated from the sludge, thereby protecting the environment.

[0013] When the rotating rod of this invention rotates, it drives the sludge squeezing block to rotate inside the separation frame. When the sludge squeezing block rotates, it uses the connecting rod to stir the sludge and clean the garbage inside the sludge. The sludge inside the separation frame is squeezed by the sludge squeezing block and discharged through the separation hole to the inside of the separation frame for processing, which increases the processing efficiency and avoids the sludge accumulating inside the separation frame, which would reduce the sludge processing efficiency.

[0014] When the sludge squeezing block of this invention squeezes the sludge inside the separation frame, the garbage inside the sludge will adhere to the surface of the separation frame, which will reduce the separation efficiency of the garbage. The rack plate uses the rotation of the sludge squeezing block to clean the inner wall of the separation frame, so that the garbage can be separated by the turbine blades accumulating on the right side of the separation frame, avoiding the garbage from accumulating inside the sludge and causing environmental pollution.

[0015] When the separator of this invention rotates, the sludge will enter the interior of the processing box through the separation hole and slide into the interior of the unloading frame after contacting the surface of the arc slider. The sludge is discharged through the unloading hole at both ends of the scraper. The sludge scraped off the surface of the separator by the scraper is discharged from the processing box through the unloading hole.

[0016] When the separator of this invention rotates, it uses a slider to push the arc-shaped movable plate downward. When the arc-shaped movable plate moves downward, it squeezes the sludge inside the unloading rack and discharges it from the inside of the unloading rack, thus avoiding the accumulation of sludge inside the unloading rack and affecting the sludge treatment efficiency.

The separation mechanism 7 includes a disc frame 10, a separation frame 11, a sealing door 12, and a storage pipe 13. The disc frame 10 is fixedly connected to the inner wall of the processing box 1. The separation frame 11 is rotatably connected to the disc frame 10 via a bearing. The storage pipe 13 is fixedly connected to the separation frame 11. The top of the storage pipe 13 is hinged to the sealing door 12. The outer surface of the storage pipe 13 is rotatably connected to the inner wall of the processing box 1 via a rotating shaft. The storage pipe 13 passes through the processing box 1 and is fixedly connected to the output end of the motor 6. The outer surface of the separation frame 11 has multiple separation holes. When the present invention needs to process sludge, the feeding frame 3 is used to push the sludge into the interior of the disc frame 10 for processing. When the rotating rod 20 rotates, the turbine blades 23 push the sludge inside the disc frame 10 into the interior of the separation frame 11 for processing. When the separation frame 11 rotates, the separation holes are used to throw the sludge out of the interior of the separation frame 11 for processing. The garbage in the sludge will accumulate inside the separation frame 11 and be separated from the sludge to protect the environment.

[0022] The separation frame 11 includes a rotating rod 20, a sludge squeezing block 21, a circular ring plate 22, a turbine blade 23, and a waste cleaning mechanism 24.

When the sludge squeezing block 21 of the present invention squeezes the sludge inside the separation frame 11, the garbage inside the sludge will adhere to the surface of the separation frame 11, resulting in a reduction in the garbage separation efficiency. The rack plate 32 uses the rotation of the sludge squeezing block 21 to clean the inner wall of the separation frame 11, so that the garbage can be separated by the turbine blade 23 accumulating on the right side of the separation frame 11, avoiding the garbage from accumulating inside the sludge and causing environmental pollution.

The arc slider 40 is fixedly connected to the inner wall of the processing box 1. The top of the inner wall of the discharge rack 42 is provided with a pushing mechanism 41. When the separation rack 11 rotates, the sludge will enter the interior of the processing box 1 through the separation hole and come into contact with the surface of the arc slider 40 and slide into the interior of the discharge rack 42 to discharge the sludge. The discharge holes 44 are provided at both ends of the scraper 43 so that after the scraper 43 scrapes the sludge on the surface of the separation rack 11, it will be discharged into the interior of the processing box 1 through the discharge hole 44 for unified collection and processing. The top of scraper 43 contacts the outer surface of separator 11.

The storage tube 13 passes through the processing box 1 and is fixedly connected to the output end of the motor 6. The outer surface of the separation frame 11 has multiple separation holes.

[0030] The separation frame 11 includes a rotating rod 20, a sludge squeezing block 21, a circular ring plate 22, a turbine blade 23, and a waste cleaning mechanism 24. The left side of the rotating rod 20 is fixedly connected to the output end of the motor 4, and the outer surface of the rotating rod 20 is fixedly connected to the turbine blade 23.

The waste cleaning mechanism 24 is provided on the outer surface of the sludge squeezing block 21. The sludge compression block 21 contacts the inner wall of the separation frame 11.

[0031] The left side of the separating frame 11 is connected to the interior of the disc frame 10, the right side of the separating frame 11 is connected to the interior of the storage pipe 13, and the top of the disc frame 10 is connected to the bottom of the feeding frame 3.

[0032] The garbage collection mechanism 24 includes a groove 30, a bottom plate 31 and a rack plate 32. The top of the sludge squeezing block 21 is provided with a groove 30, the bottom plate 31 is fixedly connected to the inner wall of the groove 30, and the top of the bottom plate 31 is fixedly connected to the rack plate 32. The outer surface of the rack plate 32 is in contact with the inner wall of the separator 11.

[0033] The processing box 1 includes an arc slider 40, a pushing mechanism 41, a discharge rack 42, a scraper 43, and a discharge hole 44. The discharge rack 42 is connected to the bottom of the processing box 1, the scraper 43 is fixedly connected to the inner wall of the discharge rack 42, and the scraper 43 is provided with a discharge hole 44. The arc slider 40 is fixedly connected to the inner wall of the processing box 1, and the pushing mechanism 41 is provided at the top of the inner wall of the discharge rack 42. The top of scraper 43 contacts the outer surface of separator 11.

[0034] The discharge holes 44 are located at the front and rear ends of the scraper 43, and the discharge rack 42 extends out of the bottom outer end of the processing box 1.

[0035] The feeding mechanism 41 includes an arc-shaped movable plate 50, a slider 51, and a pressing plate 52. The arc-shaped movable plate 50 is movably connected to the outer surface of the arc-shaped slider 40 via a rotating shaft. The end of the arc-shaped movable plate 50 near the unloading rack 42 is fixedly connected to the pressing plate 52. Multiple sliders 51 are fixedly connected to the top of the arc-shaped movable plate 50. When the separation rack 11 rotates, it uses the sliders 51 to push the arc-shaped movable plate 50 downward. When the arc-shaped movable plate 50 moves downward, it squeezes the sludge inside the unloading rack 42 and discharges it from the inside of the unloading rack 42, thus preventing the sludge from accumulating inside the unloading rack 42 and affecting the sludge processing efficiency.

[0036] The extrusion plate 52 is an elastic steel plate or spring sheet, used to provide a restoring force after the arc-shaped movable plate 50 is pushed.

[0037] The arc-shaped movable plate 50 is located above the unloading hole 44.

[0038] The outer surface of the slider 51 is adapted to the inner wall of the separation hole, and the arc-shaped movable plate 50 is adapted to the inner wall of the unloading rack 42.

[0039] The turbine blade 23 is fixed on the rotating rod 20 and extends into the interior of the disc frame 10. The sludge extrusion block 21 is arc-shaped and fits the inner wall of the separation frame 11.

[0040] A specific application of this embodiment is as follows: When treating sludge inside sewage, the sludge is pushed into the disc frame 10 through the feed rack 3 for processing. The motor 4 is started to drive the rotating rod 20 to rotate, and the turbine blades 23 push the sludge into the separation frame 11. The separation frame 11 rotates in the opposite direction to the rotating rod 20 under the drive of the motor 6, thereby improving the compression efficiency of the sludge compression block 21. When the rotating rod 20 rotates, it drives the sludge compression block 21 to compress the sludge and discharge it through the separation hole for sludge processing. After the sludge is pushed out of the outer end of the separation frame 11 by the sludge compression block 21, the rack plate 32 rotates to press against the inner wall of the separation frame 11. During the cleaning process, the debris inside the sludge adhering to the separator 11 is scraped off by the rack plate 32. The debris accumulates on the right inner wall of the separator 11 due to the rotation of the turbine blade 23. When the sludge is pushed out of the separator 11 by the sludge extrusion block 21, the sludge is unloaded by the contact between the scraper 43 and the surface of the separator 11, preventing the sludge from sticking to the surface of the separator 11 and affecting the processing effect. When the separator 11 rotates, it uses the separation hole to squeeze the slider downward. When the slider pushes the arc-shaped movable plate 50 downward, it squeezes the sludge on the surface of the scraper 43 through the discharge hole 44, increasing the processing efficiency.

[0041] Preferably, a gap of 0.5-1mm is left between the outer surface of the sludge extrusion block 21 and the inner wall of the separation frame 11, or the contact surfaces of the two are made of a low-friction coefficient material such as polytetrafluoroethylene, in order to avoid excessive friction.

[0042] Preferably, when the separator 11 rotates, the separation holes on its outer surface are aligned with the slider 51 in sequence, and the slider 51 is inserted into the separation hole. As the separator continues to rotate, the inner wall of the separation hole pushes the slider 51 downward, thereby causing the arc movable plate 50 to swing downward around the axis of rotation and squeeze the sludge in the unloading rack 42. After the separation hole has rotated, the slider 51 is reset under the elastic force of the squeezing plate 52.

[0043] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
