Technical Field

[0001] This utility model relates to the field of oil sludge treatment technology, and in particular to a heating and cleaning device for the inner wall of heavy oil sewage drainage pipes. Background Technology

[0002] Traditional drainage pipes (especially restaurant wastewater pipes) are prone to accumulating high-viscosity sludge on their inner walls. Conventional cleaning methods have the following drawbacks: 1. Mechanical cleaning with scrapers is prone to sludge adhesion to the scrapers, and the high hardness of cold sludge makes cleaning difficult and ineffective; 2. Chemical cleaning is costly and environmentally polluting, and has low dissolving efficiency for stubborn sludge; 3. High-pressure water jet cleaning requires large amounts of water, and the sludge coagulates upon contact with cold water, increasing the difficulty of removal. Therefore, there is an urgent need for an efficient, environmentally friendly, and safe sludge cleaning device. Utility Model Content

[0020] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0021] Example:

[0022] The accompanying drawings illustrate a specific embodiment of the heating and cleaning device for the inner wall of a heavy oil wastewater drainage pipe according to this utility model. Figure 1 It mainly includes a positioning sleeve 1, a push-pull mechanism 2 that is detachably installed in the middle of the positioning sleeve 1, and a cleaning mechanism 3 connected to the push-pull mechanism 2.

[0023] Specifically, the push-pull mechanism 2 includes an outer sleeve 201 detachably connected to the positioning sleeve 1, a middle sleeve 202 slidably connected to the outer sleeve 201, and an inner push rod 203 slidably connected to the middle sleeve 202. The positioning sleeve 1 is used to match the pipe end of pipe A, enabling the positioning and installation of the entire device. The outer sleeve 201 is detachably connected to the positioning sleeve 1, which can be achieved by a threaded connection, allowing the positioning sleeve 1 to be detachably replaced with different sizes to match pipes A of different sizes.

[0024] The rear end of the inner push rod 203 is detachably connected to an outer rod 204. The outer rod 204 passes through the outer sleeve 201 and the middle sleeve 202 in sequence and connects to the inner push rod 203. By pushing the outer rod 204, the inner push rod 203 can be further pushed, and the middle sleeve 202 can be moved within the outer sleeve 201. In reverse operation, the inner push rod 203 and the middle sleeve 202 can be retracted into the outer sleeve 201, thereby reducing the overall volume. The outer rod 204 and the inner push rod 203 are detachably connected by a threaded connection, allowing the outer rod 204 to be replaced with different lengths to push the cleaning mechanism 3 to different depths.

[0025] In practical applications, the lengths of the outer sleeve 201, middle sleeve 202, and inner push rod 203 of the push-pull mechanism 2 can be adjusted according to actual usage requirements to accommodate the cleaning of pipes A of different lengths.

[0026] Furthermore, the cleaning mechanism 3 specifically includes a mounting base 301, a motor 4 is provided inside the mounting base 301, and a rotating head 302 is provided at the front end of the mounting base 301. The rotating head 302 is embedded in the mounting base 301, and the motor 4 is connected to drive the rotating head 302, which can rotate 360°.

[0027] The outer surface of the rotating head 302 is provided with multiple telescopic blocks 303 evenly distributed around it. Each telescopic block 303 has an electromagnetic induction heating coil 304 on its surface. The rotating head 302 can drive the electromagnetic induction heating coil 304 to rotate, achieving uniform heating from all directions. The electromagnetic induction heating coil 304 is electrically connected to a control circuit, which is existing technology and will not be described in detail here. Using the electromagnetic induction heating coil 304 to heat the sludge on the inner wall of pipe A results in high heating efficiency, short heating time, and uniform heating. This softens the sludge, reduces its viscosity, and decreases mechanical resistance, thereby achieving efficient sludge removal.

[0028] The rotating head 302 is internally equipped with a cylinder 5 and a protrusion 6 driven by the cylinder 5. Each telescopic block 303 is telescopically mounted inside the rotating head 302 via a spring 7, and each telescopic block 303 abuts against the protrusion 6. In the initial state, the telescopic blocks 303 are pressed inward into the rotating head 302 under the action of the spring 7. When the cylinder 5 extends, it drives the protrusion 6 to extend, and the telescopic blocks 303 are pushed outward by the protrusion 6. The spring 7 is compressed, and the electromagnetic induction heating coil 304 moves closer to the inner wall of the pipe A, thereby improving the heating efficiency.

[0029] A temperature sensor 8 is embedded inside the front end of the rotating head 302 to monitor the heating temperature.

[0030] Furthermore, a negative pressure suction hood 305 is fixedly installed at the rear end of the mounting base 301. The surface of the negative pressure suction hood 305 is provided with several negative pressure suction ports 9 arranged in a 360° circle. The interior of the negative pressure suction hood 305 is provided with a conveying channel 10 communicating with the negative pressure suction ports 9. The rear end of the negative pressure suction hood 305 is provided with a suction interface 11 communicating with the conveying channel 10. The suction interface 11 is connected to a suction hose 308. The suction hose 308 can be connected to the recovery tank through a suction pump.

[0031] A scraper ring 306 is fitted onto a negative pressure suction hood 305. A positioning step 12 for positioning the scraper ring 306 is provided on the outer surface of the negative pressure suction hood 305. A positioning seat 307 for positioning the scraper ring 306 is detachably installed at the rear end of the negative pressure suction hood 305. The scraper ring 306 is positioned between the positioning step 12 and the positioning seat 307. The positioning seat 307 is locked to the negative pressure suction hood 305 by screws 13. By removing the screws 13, the positioning seat 307 and the scraper ring 306 can be removed, so that the scraper ring 306 can be replaced with different sizes to match different sizes of pipes A.

[0032] The suction port 11 extends from one side of the positioning seat 307 to the other side of the positioning seat 307. The positioning sleeve 1 is provided with a guide sleeve 14 for guiding the movement of the suction hose 308. The suction hose 308 is slidably installed in the guide sleeve 14. The positioning seat 307 is connected to the front end of the inner push rod 203, and the entire cleaning mechanism 3 can be moved back and forth by the inner push rod 203.

[0033] When the device of this utility model is in operation, as follows: Figure 2 As shown, first insert the front cleaning mechanism 3 into pipe A, then insert the positioning sleeve 1 into the pipe opening of pipe A, as shown. Figure 3 As shown, at this time, cylinder 5 extends, driving protrusion 6 extends, telescopic block 303 is squeezed outward by protrusion 6, spring 7 is compressed, and electromagnetic induction heating coil 304 moves closer to the inner wall of pipe A, improving heating efficiency. Then, the suction pump is started, and the external rod 204 is slowly pushed forward, as shown... Figure 4 As shown, the outer rod 204 can further push the inner push rod 203, and together with the middle sleeve 202, move within the outer sleeve 201. The inner push rod 203 pushes the entire cleaning mechanism 3 forward slowly. The heated and softened sludge on the inner wall of pipe A is scraped off by the scraper ring 306, and then sucked out by the negative pressure suction port 9. It enters the suction hose 308 through the suction port 11 via the conveying channel 10 and is collected and recycled into the recovery tank. During the entire process of the device moving forward, while using the electromagnetic induction heating coil 304 for heating, the entire rotating head 302 can also be driven to rotate by the motor 4, thereby driving the electromagnetic induction heating coil 304 to rotate, achieving uniform heating in all directions.

They should not be used to limit the protection scope of this utility model. All modifications made in accordance with the spirit and essence of the main technical solution of this utility model should be covered within the protection scope of this utility model.
