Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a sludge discharge device. Background Technology

[0002] Sedimentation is a type of wastewater treatment equipment widely used in industry. Industrial wastewater generated during industrial production is discharged into sedimentation tanks. Most sedimentation tanks work by using gravity sedimentation to settle some impurities in the wastewater to the bottom of the tank.

[0003] Since sedimentation tanks are used to settle wastewater, the settled sludge needs to be discharged. However, the existing sludge discharge structure of sedimentation tanks has certain drawbacks. First, the existing sludge discharge structure cannot dewater the sludge, and the discharged sludge needs to be dewatered again, which increases the cost of water treatment. Second, the existing sludge discharge structure cannot scrape and clean the inner wall of the sedimentation tank at the same time, resulting in incomplete sludge discharge, which has certain disadvantages. Utility Model Content

[0004] To solve the above problems, this utility model provides a sludge discharge device, which is achieved through the following technical solution.

[0006] Furthermore, the power mechanism includes a transmission box, which is fixedly connected to the top of one end of the filter press cylinder. A servo motor is fixedly connected to the top of the transmission box, and the output shaft of the servo motor is fixedly connected to the rotating rod.

[0007] Furthermore, two transmission rods are connected through the outer surface of the transmission box.

[0008] Furthermore, a third helical gear is fixedly connected to the other end of the transmission rod, an annular rotating frame is rotatably connected to the outer surface of the transmission rod, and one end of the suspension rod is fixedly connected to the annular rotating frame. A fourth helical gear is fixedly connected to the top of the annular rotating frame, and the third helical gear and the fourth helical gear are meshed together.

[0009] Furthermore, the bottom of the filter press cylinder is 5-10cm away from the inner wall of the sedimentation tank, the pitch of the spiral blades is equal at the end near the inside of the sedimentation tank, and the pitch of the spiral blades gradually decreases at the end near the sludge outlet pipe. The outer surface of the filter press cylinder near the storage tank is provided with filter pressing holes.

[0010] Furthermore, the bottom of the storage box is set as an inclined surface, and a mud discharge pipe is connected through the downward inclined end of the bottom of the storage box, and a sealing cap is fixedly connected to one end of the mud discharge pipe.

[0011] The beneficial effects of this utility model are that, during the operation of this device, the power mechanism is first turned on, which drives the spiral blades to lift and filter the sludge inside the sedimentation tank through the filter press cylinder.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-3 As shown, the present invention has the following specific embodiments.

[0024] Example:

[0025] A sludge discharge device includes a sedimentation tank 1, a filter press 2 fixedly connected to the center of the sedimentation tank 1, two storage tanks 4 fixedly connected to the end of the filter press 2 away from the sedimentation tank 1, a rotating rod 21 penetrating through the top of the filter press 2, a spiral blade 211 fixedly connected to the end of the rotating rod 21 extending into the filter press 2, a sludge discharge pipe 23 penetrating through the outer surface of the filter press 2 and communicating with the storage tanks 4, two sludge scraping strips 3 rotatably connected inside the sedimentation tank 1, a reinforcing rod 31 fixedly connected to the sludge scraping strips 3, a suspension rod 32 fixedly connected to the reinforcing rod 31, and a power mechanism for driving the sludge scraping strips 3 to move and driving the rotating rod 21 to rotate.

[0026] By adopting the above technical solution, when using the device, first turn on the power mechanism, which can drive the spiral blades 211 to lift and filter the sludge inside the sedimentation tank 1 through the filter press cylinder 2. The filtered wastewater is reintroduced into the inner wall of the sedimentation tank 1 through the filter press hole 22. The dewatered sludge is fed into the storage tank 4 through the sludge outlet pipe 23. At the same time, the power mechanism can drive the sludge scraper 3 to rotate inside the sedimentation tank 1, so that the sludge scraper 3 can scrape off the sludge adhering to the inner wall of the sedimentation tank 1. The structure is reasonable, which can facilitate sludge scraping and sludge discharge inside the sedimentation tank 1, and at the same time, sludge can be dewatered during discharge.

[0027] Specifically, the power mechanism includes a transmission box 5, which is fixedly connected to the top of one end of the filter press cylinder 2. A servo motor 51 is fixedly connected to the top of the transmission box 5, and the output shaft of the servo motor 51 is fixedly connected to the rotating rod 21.

[0028] Two transmission rods 52 are connected through the outer surface of the transmission box 5. One end of the transmission rod 52 is fixedly connected to a second helical gear 521, and the other end of the rotating rod 21 is fixed to a first helical gear 212, which meshes with the second helical gear 521.

[0029] The other end of the transmission rod 52 is fixedly connected to a third helical gear 522. The outer surface of the transmission rod 52 is rotatably connected to an annular rotating frame 53, and one end of the suspension rod 32 is fixedly connected to the annular rotating frame 53. The top of the annular rotating frame 53 is fixedly connected to a fourth helical gear 531, and the third helical gear 522 and the fourth helical gear 531 are meshed together.

[0030] The bottom of the filter press cylinder 2 is 5-10cm away from the inner wall of the sedimentation tank 1. The pitch of the spiral blades 211 is equal at the end near the inside of the sedimentation tank 1, and the pitch of the spiral blades 211 gradually decreases at the end near the sludge outlet pipe 23. The outer surface of the filter press cylinder 2 near the storage tank 4 is provided with filter press holes 22.

[0031] By adopting the above technical solution, the power mechanism can drive the spiral blades 211 to lift and filter the sludge inside the sedimentation tank 1, and drive the scraper strips 3 to scrape the sludge on the inner wall of the sedimentation tank 1. Specifically, the servo motor 51 can drive the rotating rod 21 to rotate, and the rotating rod 21 can drive the spiral blades 211 to rotate. Since the filter press cylinder 2 is 5-10 cm away from the inner wall of the sedimentation tank 1, and the rotating rod 21 extends to the bottom of the filter press cylinder 2, the rotating spiral blades 211 can lift the concentrated sludge inside the sedimentation tank 1 through the filter press cylinder 2. The lifted sludge is then filtered through the filter holes 22 in the filter press cylinder 2, allowing wastewater to flow into the sedimentation tank 1, and the squeezed sludge passes through the filter press cylinder 2. The sludge is fed into the storage tank 4 through the through-hole sludge pipe 23, which facilitates the sludge pressing and lifting, and the output of the sludge after dewatering. At the same time, the rotating rod 21 can drive the first helical gear 212 to rotate, the first helical gear 212 can drive the second helical gear 521 to rotate, the second helical gear 521 can drive the third helical gear 522 to rotate through the transmission rod 52, the third helical gear 522 can drive the fourth helical gear 531 to rotate, and the fourth helical gear 531 can drive the annular rotating frame 53 to rotate on the transmission box 5. Since the sludge scraper 3 is connected to the annular rotating frame 53 through the set suspension rod 32, it can drive the sludge scraper 3 to rotate inside the sedimentation tank 1, thereby scraping off the sludge adhering to the inner wall of the sedimentation tank 1.

[0032] Specifically, the bottom of the storage box 4 is set as an inclined surface, and the bottom of the storage box 4 is inclined downward and connected to the mud discharge pipe 41. One end of the mud discharge pipe 41 is fixedly connected to a sealing cap.

[0033] By adopting the above technical solution, the bottom of the storage tank 4 is designed to be inclined so that the sludge can slide down, and the sludge discharge pipe 41 that runs through the bottom of the storage tank 4 can facilitate the discharge of the internal sludge.
