Description

Technical Field

[0001] This utility model relates to the field of sludge discharge device technology, and more specifically, to a high-efficiency sludge discharge device for sewage treatment. Background Technology

[0002] In the wastewater treatment process, wastewater needs to be filtered repeatedly to trap impurities such as sludge through the filter structure. As filtration continues, sludge will accumulate and therefore needs to be removed in a timely manner.

[0003] Chinese patent application CN215609586U discloses a high-efficiency sludge removal device for treating aquaculture wastewater, belonging to the field of sludge removal devices. The device includes a treatment tank, with a wastewater tank engaged in the middle of one side of the top of the treatment tank; a first slot is opened at one end of one side of the wastewater tank, and a support frame is inserted through the inner wall of the tank, with a first filter screen engaged in the inner wall of the support frame, and a movable handle is fixed in the middle of one side of the outer wall; a sludge squeezing plate is engaged in the other end of the inner wall of the wastewater tank.

[0004] This technical solution intercepts most of the sludge in the sewage tank through a first filter screen. An air pump is then activated to compress the sludge through a telescopic rod, moving the sludge. The support frame is then removed, and the sludge is discharged into an arc-shaped groove using the sludge compression plate, facilitating cleaning and improving the device's practicality. However, this solution requires removing the support frame and pushing the sludge into the arc-shaped groove during sludge discharge, forcing a halt to sewage filtration until the sludge is completely removed, thus reducing sewage treatment efficiency. Therefore, this application proposes a high-efficiency sludge discharge device for sewage treatment to address these issues. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency sludge removal device for wastewater treatment, so as to solve the problems mentioned in the background art above:

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-efficiency sludge removal device for sewage treatment includes a filter box, a switching frame movably installed inside the filter box, a first filter cylinder movably installed on one side of the switching frame, a second filter cylinder movably installed on the other side of the switching frame, and a rotating rod fixedly connected to the middle of the switching frame, the rotating rod being rotatably connected to the filter box.

[0008] The bottom of the first and second filter cartridges are fixedly connected with connecting rods. Movable slots are provided on both sides of the switching frame, and the connecting rods are movably installed in the movable slots. A cleaning port is provided on one side of the filter box.

[0009] By adopting the above technical solution, the switching frame is rotated to switch between filter cylinder No. 1 and filter cylinder No. 2, so that the sewage treatment work will not be interrupted due to the sludge discharge operation of filter cylinder No. 1 and filter cylinder No. 2, thus improving the efficiency of sewage treatment. Filter cylinder No. 1 and filter cylinder No. 2 move upward in the cleaning port and then tilt downward, so that the sludge inside can be easily poured out and cleaned.

[0010] Preferably, a sewage inlet is provided at the upper part of the filter box, an outlet is provided at the center of the bottom surface of the filter box, and a support leg is fixedly connected to the bottom of the filter box, with the support leg array located outside the outlet.

[0011] By adopting the above technical solution, the sewage inlet is used to introduce sewage and corresponds to either the No. 1 or No. 2 filter cartridge, thereby introducing sewage.

[0012] Preferably, the first and second filter cylinders have several filter holes at their lower positions. The rotating rod is rotatably connected to the filter box via a bearing. A mounting bracket is fixedly connected to the filter box, and a stepper motor is fixedly connected to the mounting bracket. The output shaft of the stepper motor is fixedly connected to the upper end of the rotating rod via a coupling.

[0013] By adopting the above technical solution, the filter holes are set on the No. 1 or No. 2 filter cylinder to filter sewage and intercept sludge and other impurities inside.

[0014] Preferably, positioning slots are provided on both sides of the switching frame above the movable slot, and positioning rods are fixedly connected to the upper parts of the first filter cylinder and the second filter cylinder, and the positioning rods are movably installed in the positioning slots.

[0015] By adopting the above technical solution, the positioning rod and the positioning groove are installed together, so that the No. 1 filter cylinder and the No. 2 filter cylinder remain vertically upward, which facilitates the introduction of sewage.

[0016] Preferably, limiting plates are fixedly connected to both ends of the connecting rod, and the limiting plates are located on the outer side of the switching frame.

[0017] By adopting the above technical solution, the limiting plate is used to prevent the connecting rod from detaching, thereby preventing the No. 1 filter cartridge and the No. 2 filter cartridge from detaching.

[0018] Preferably, a storage box is fixedly connected inside the filter box at the inner side of the cleaning port, a baffle is movably installed inside the storage box, and a spring is movably installed inside the storage box at the lower position of the baffle.

[0019] By adopting the above technical solution, the baffle is turned upward to block the sewage, preventing the sewage from being thrown out of the cleaning port during the rotation process.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1) This sludge removal device uses a switching frame to rotate either the No. 1 or No. 2 filter cylinder to a position below the sewage inlet, allowing sewage to enter and undergo filtration. When there is too much sludge inside, simply rotate the switching frame to switch between the No. 1 and No. 2 filter cylinders, ensuring that the sewage treatment process is not interrupted and improving the efficiency of the sewage treatment process.

[0022] 2) After the No. 1 or No. 2 filter cylinder in this sludge discharge device is rotated into the cleaning port, it is pulled upward and raised, and then tilted to the side to make it easier to pour out and clean the sludge and other impurities inside. Attached Figure Description

[0029] Example 1, please refer to Figures 1 to 4 A high-efficiency sludge removal device for sewage treatment includes a filter box 1, a switching frame 5 movably installed inside the filter box 1, the switching frame 5 rotating inside the filter box 1, a first filter cylinder 6 movably installed on one side of the switching frame 5, and a second filter cylinder 7 movably installed on the other side of the switching frame 5. The first filter cylinder 6 and the second filter cylinder 7 are used to introduce sewage and filter and intercept it. A rotating rod 14 is fixedly connected to the middle of the switching frame 5. The rotating rod 14 is rotatably connected to the filter box 1 and drives the switching frame 5 to rotate.

[0030] A sewage inlet 3 is provided at the upper part of the filter box 1 to guide sewage in. A discharge outlet 4 is provided at the center of the bottom surface of the filter box 1 to guide sewage out. Both the sewage inlet 3 and the discharge outlet 4 are fixedly connected to the filter box 1. Support legs 2 are fixedly connected to the bottom of the filter box 1 and are arranged outside the discharge outlet 4. The support legs 2 support and fix the filter box 1.

[0031] Several filter holes 8 are provided at the bottom of filter cylinder 6 and filter cylinder 7. The filter holes 8 filter the sewage in filter cylinder 6 and filter cylinder 7 and intercept sludge and other impurities. The rotating rod 14 is rotatably connected to the filter box 1 through the bearing 15. The filter box 1 is fixedly connected to the mounting bracket 16, and the mounting bracket 16 is fixedly connected to the stepper motor 18. The stepper motor 18 is located above the rotating rod 14. The output shaft of the stepper motor 18 is fixedly connected to the upper end of the rotating rod 14 through the coupling 17, so that the stepper motor 18 can drive the rotating rod 14 and the switching bracket 5 below the rotating rod 14.

[0032] Positioning slots 13 are provided on both sides of the switching frame 5 above the movable slot 11. Positioning rods 12 are fixedly connected to the upper part of the first filter cylinder 6 and the second filter cylinder 7. The positioning rods 12 are movably installed in the positioning slots 13. The positioning rods 12 are inserted into the positioning slots 13 so that the first filter cylinder 6 and the second filter cylinder 7 remain vertically upward.

[0033] The steps for using this utility model are as follows: The first filter cylinder 6 or the second filter cylinder 7 is rotated sequentially to a position below the sewage inlet 3. When the first filter cylinder 6 is below the sewage inlet 3, the second filter cylinder 7 is located in the cleaning inlet 19. Taking the first filter cylinder 6 being below the sewage inlet 3 as an example, sewage is introduced through the sewage inlet 3 and flows downwards into the first filter cylinder 6. Several filters are installed at the lower part of the first filter cylinder 6. Hole 8 filters wastewater, trapping sludge and other impurities in filter cartridge 6. When the sludge in filter cartridge 6 needs to be treated, stepper motor 18 is started, causing rotating rod 14 and switching frame 5 to rotate. Switching frame 5 drives filter cartridge 6 and filter cartridge 7 to switch positions, allowing filter cartridge 7 to move below wastewater inlet 3 to continue wastewater treatment, while filter cartridge 6 can perform sludge discharge and other cleaning work. This ensures that sludge discharge and wastewater filtration do not interfere with each other, improving the efficiency of wastewater filtration.

[0034] Example 2, please refer to Figures 1 to 5The difference from the basic embodiment 1 is that a connecting rod 9 is fixedly connected to the bottom of the first filter cartridge 6 and the second filter cartridge 7. Movable slots 11 are opened on both sides of the switching frame 5. The rods on both sides of the connecting rod 9 extend into the corresponding movable slots 11 on both sides of the switching frame 5. The connecting rod 9 is movably installed in the movable slots 11. A cleaning port 19 is opened on one side of the filter box 1. The cleaning port 19 is connected to the external environment, so that the first filter cartridge 6 and the second filter cartridge 7 can easily come into contact with the external environment.

[0035] Limiting plates 10 are fixedly connected to both ends of the connecting rod 9. The limiting plates 10 are located on the outside of the switching frame 5, thereby preventing the first filter cartridge 6 and the second filter cartridge 7 from detaching from the switching frame 5.

[0036] A storage box 20 is fixedly connected inside the filter box 1, located inside the cleaning port 19. A baffle 21 is movably installed inside the storage box 20. The baffle 21 blocks the liquid thrown out when the first filter cartridge 6 and the second filter cartridge 7 rotate, preventing the liquid from being thrown out of the cleaning port 19. A spring 22 is movably installed inside the storage box 20, located below the baffle 21, so that the baffle 21 can be easily extended and retracted.

[0037] The steps for using this utility model are as follows: When it is necessary to clean the sludge and other impurities in the No. 1 filter cylinder 6 or the No. 2 filter cylinder 7, rotate the No. 1 filter cylinder 6 or the No. 2 filter cylinder 7 into the cleaning port 19, and then pull the No. 1 filter cylinder 6 or the No. 2 filter cylinder 7 upward, so that the corresponding connecting rod 9 and positioning rod 12 move upward. The positioning rod 12 disengages from the positioning groove 13, and the connecting rod 9 moves upward in the movable groove 11. When the connecting rod 9 moves to the uppermost position of the movable groove 11, it rotates outward, so that the No. 1 filter cylinder 6 or the No. 2 filter cylinder 7 presses the baffle 21 downward, so that the baffle 21 retracts downward in the storage box 20 and compresses the spring 22, so that the outlet of the No. 1 filter cylinder 6 or the No. 2 filter cylinder 7 can easily extend downward into the cleaning port 19, making it easy to pour out the sludge inside and for workers to clean it manually.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
