Technical Field

[0001] This utility model relates to the field of sludge cleaning technology, specifically a reciprocating sludge scraper machine. Background Technology

[0002] As we all know, industrial production generates a large amount of industrial wastewater and industrial pollutants, so wastewater storage equipment such as sewage tanks are needed for centralized treatment and discharge. During the treatment of wastewater in the sewage tank, some of the sludge will remain at the bottom of the sewage tank and needs to be cleaned regularly to avoid long-term accumulation that would reduce the quality of wastewater treatment. Therefore, reciprocating sludge scrapers are needed to treat the sludge.

[0003] Regarding the aforementioned technologies, the applicant believes that when the reciprocating sludge scraper is working, the drive motor rotates the lead screw, causing the movable seat mounted on the lead screw to reciprocate linearly, thereby moving the scraper along the bottom of the sewage treatment tank to clean the deposited sludge. However, during operation, some sludge adheres to the scraper surface, increasing the load on the scraper during subsequent movements. This not only exacerbates the equipment's operating resistance but may also affect the stability of the device's operation. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figures 1 to 4This embodiment provides a technical solution: a reciprocating sludge scraper. The reciprocating sludge scraper is installed on the main body 2 of the sewage treatment tank. The bottom end of the main body 2 of the sewage treatment tank has a sludge discharge port to facilitate the discharge of sludge from inside the main body 2 of the sewage treatment tank. It includes a processing mechanism 3, which is located at one end of the equipment box 1. The processing mechanism 3 includes a water storage tank 301 located below one end of the equipment box 1. A water pump is installed inside the water storage tank 301. This water pump is existing technology and will not be described in detail here. A water delivery pipe 303 is installed through the inside of the water storage tank 301. A [unclear - possibly a device or device] is installed at the end of the water delivery pipe 303 away from the water storage tank 301. The high-pressure nozzle 307 has a movable plate 306 at its top, and a cylinder 305 at the top of the movable plate 306. The basic working principle of the cylinder 305 is to achieve mechanical energy conversion through pneumatic transmission: compressed air enters the cylinder through the air inlet, pushing the piston and driving the piston rod to move linearly, thus converting pneumatic energy into mechanical energy. During operation, the exhaust port simultaneously discharges the residual air in the cylinder, and the piston reciprocates under the action of the air pressure difference, thereby driving the mechanical parts to complete push, pull and other actions. When selecting the cylinder, the appropriate model should be selected according to the actual needs. All the components required in the cylinder 305 are existing technologies and will not be described in detail below.

[0031] The cylinder 305 drives the movable plate 306 to move laterally. The top of the cylinder 305 is equipped with a processing box 304. The top of the water storage tank 301 is provided with a water inlet 302, which allows water to be added to the inside of the water storage tank 301. The inside of the water inlet 302 is equipped with a sealing plug.

[0032] The effect achieved by the entire embodiment is as follows: by using the operation of cylinder 305, the movable plate 306 can be pushed downward to move the high-pressure nozzle 307 out of the treatment box 304. At this time, by using the operation of the water pump in the water storage tank 301, the water inside the water storage tank 301 is transported to the high-pressure nozzle 307 through the water supply pipe 303. Then, the high-pressure nozzle 307 sprays water to wash the working surface of the scraper body 8, effectively removing the sludge attached to the outside of the scraper body 8 and reducing subsequent operating resistance.

[0033] Example 2

[0034] Equipment boxes 1 are installed on both sides of the top of the main body 2 of the sewage treatment tank. The equipment boxes 1 can provide load-bearing capacity. A drive motor 4 is installed at one end of the equipment box 1. The drive motor 4 works on the principle that a current-carrying conductor moves under the force in a magnetic field. The stator generates a magnetic field, and the coils on the rotor become current-carrying conductors after being energized. They are subjected to Ampere force in the magnetic field, generating torque and causing the rotor to rotate. At the same time, the commutator continuously changes the direction of the coil current to ensure that the rotor rotates continuously in the same direction. When selecting the drive motor 4, the appropriate model should be selected according to the actual needs. All the components required in the drive motor 4 are existing technologies and will not be described in detail below.

[0035] The output end of the drive motor 4 is provided with a lead screw 9, and a movable seat 10 is provided on the outside of the lead screw 9. A connecting seat 5 is provided at the bottom of the movable seat 10. Connecting rods 6 are provided on both sides of the bottom of the connecting seat 5. A support seat 7 is provided at the bottom of the connecting rod 6. A scraper body 8 is provided at the bottom of the support seat 7. The support seat 7 is connected to the processing box 304 by fixing bolts, which can improve the stability of the processing box 304 during operation.

[0036] The effect achieved by the entire embodiment 2 is as follows: the drive motor 4 is started by the control switch, the drive motor 4 can drive the lead screw 9 to rotate, so that the movable seat 10 sleeved outside the lead screw 9 can perform reciprocating linear motion, thereby driving the scraper body 8 to move along the bottom of the sewage treatment tank body 2, which can clean the sludge deposited at the bottom of the sewage treatment tank body 2, and the sludge can be discharged from the sludge discharge port at the bottom of the sewage treatment tank body 2.

[0037] Example 3

[0038] A support frame 309 is provided at the bottom of the movable plate 306. The support frame 309 can provide load-bearing capacity. A mudguard 308 is provided at the bottom of the support frame 309. Five sets of high-pressure nozzles 307 are provided. The high-pressure nozzles 307 are symmetrically distributed about the internal center point of the treatment box 304, which can fully clean the working surface of the scraper body 8.

[0039] The effect achieved by the entire embodiment 3 is as follows: by using the operation of the cylinder 305, the movable plate 306 can be pushed upward to move the high-pressure nozzle 307 into the interior of the treatment box 304. Then, the bottom of the interior of the treatment box 304 is sealed by the mudguard 308, which can block the interior space of the treatment box 304, prevent sludge from entering the interior of the treatment box 304, and improve the stability of the device.

[0040] Working principle: The drive motor 4 is started by the control switch. The drive motor 4 can drive the lead screw 9 to rotate, so that the movable seat 10 sleeved outside the lead screw 9 can reciprocate linearly, thereby driving the scraper body 8 to move along the bottom of the sewage treatment tank body 2, which can clean the sludge deposited at the bottom of the sewage treatment tank body 2 and discharge the sludge from the sludge discharge port at the bottom of the sewage treatment tank body 2.

[0041] Secondly, by using the operation of cylinder 305, the movable plate 306 can be moved downward, and the high-pressure nozzle 307 can be moved out of the treatment box 304. At this time, by using the operation of the water pump in the water storage tank 301, the water inside the water storage tank 301 is transported to the high-pressure nozzle 307 through the water supply pipe 303. Then, the high-pressure nozzle 307 sprays water to wash the working surface of the scraper body 8, effectively removing the sludge attached to the outside of the scraper body 8 and reducing subsequent operating resistance.

[0042] Finally, after the scraper body 8 has finished rinsing, the cylinder 305 can be used to push the movable plate 306 upward, moving the high-pressure nozzle 307 into the treatment box 304. Then, the mud baffle 308 is used to seal the bottom of the treatment box 304, which can block the internal space of the treatment box 304, prevent sludge from entering the interior of the treatment box 304, and improve the stability of the device.
