Description

Technical Field

[0001] The invention relates to the technical field of sludge treatment, in particular to a sewage pipe sludge treatment device. Background Art

[0002] Sewers are one of the most common urban public facilities in modern society. They are mainly used as pipes for buildings to discharge sewage and rainwater. During the sewage discharge process, there are many impurities in the sewage, which can easily form silt in the sewer pipes. When the silt accumulates, it can easily cause blockage of the sewer pipes, resulting in the sewer pipes being unable to discharge sewage and rainwater normally. The silt in the sewer pipes needs to be cleaned.

[0003] The existing method of cleaning sludge in sewer pipes is basically to connect a suction pipe with a suction device, insert the suction pipe into the sludge in the sewer pipe, use the suction device and the suction pipe to suck out the sludge in the sewer pipe, and then transport the sucked out sludge to a designated discharge site to complete the dredging of the sewer pipe.

[0004] In actual use, the sludge is mostly in a slurry state. During the sewage suction process, since the pipe is usually located in the middle of the sewer pipe, after most of the sludge in the sewer pipe is sucked out, there is still a lot of sludge attached to the inner wall of the sewer pipe. At this time, relying solely on the sewage suction equipment cannot effectively clean the sludge attached to the inner wall of the pipe. The commonly used method is to flush the inner wall of the pipe with water. After flushing and cleaning, the sludge will still flow into the next section of the pipe with the water, which can easily cause the next section of the sewer pipe to be blocked. For this reason, we propose a sewer pipe sludge treatment device. Summary of the Invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] When the present invention is sucking sewage, the area of ​​the sleeve is large, so the contact area between the sleeve and the sludge can be increased, so as to reduce the pressure between the sleeve and the sludge and make the pressure less than the critical bearing capacity of the sludge, so that the sleeve can float on the surface of the sludge, ensuring that the sewage suction pipe will not sink too deep into the sludge, causing the sludge to compress the sewage suction pipe and deform it, thereby affecting the sewage suction efficiency. Since the device uses the limit bar and the limit plate to limit the sleeve and the inner plate in the contracted state in the initial state, when the sewage suction work is completed, the motor can be controlled to rotate, and the motor uses the traction rope to lift one end of the limit plate, and the fixed spring pops out the inner plate, so that the arc plate fits the inner wall of the sewer pipe. Later, in the process of retracting the sewage suction pipe, the arc plate is used to collect and clean the sludge remaining on the inner wall of the sewer pipe, thereby improving the cleaning effect of the sludge remaining on the inner wall of the sewer pipe.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figure 1-11 The present invention provides a technical solution: a sewer sludge treatment device, comprising a sewage suction pipe 1 and a sewage suction pump 11, one end of the sewage suction pipe 1 is fixedly connected to the sewage suction pump 11, the sewage suction pump 11 is respectively provided with an inlet end and an outlet end, and the sewage suction pipe 1 is fixedly docked with the inlet end of the sewage suction pump 11.

[0034] Furthermore, first connect the output end of the sewage suction pump 11 to the external pipe, connect the external pipe to the sludge collection equipment, then place one end of the sewage suction pipe 1 into the sewer pipe, start the sewage suction pump 11, and transfer the sludge in the sewer pipe to the sludge collection equipment through the sewage suction pipe 1 and the sewage suction pump 11, thereby completing the sludge cleaning work in the sewer pipe.

[0035] Combined with attachment Figure 1 、 Figure 2 、 Figure 8 、 Figure 9 and Figure 10 As shown, one end of the sewage suction pipe 1 away from the inlet end of the sewage suction pump 11 is fixedly connected to a metal pipe 2, a mounting bracket 22 is fixedly connected inside the metal pipe 2, a plurality of mounting plates 23 are fixedly connected below the mounting bracket 22, and a blade 24 is slidably connected to the bottom of the mounting plate 23. The bottom of the metal pipe 2 is fixedly connected to an internally threaded pipe 21, and the inner wall of the internally threaded pipe 21 is provided with a thread groove. A plurality of buffer springs 25 are provided between the top of the blade 24 and the inner top wall of the mounting plate 23. The blade 24 faces downward, and the inclination angle of the blade 24 is opposite to the screwing direction of the thread groove on the inner wall of the internally threaded pipe 21.

[0036] Furthermore, since the metal pipe 2 and the internally threaded pipe 21 are made of steel, the metal pipe 2 cooperates with the internally threaded pipe 21 to increase the weight of one end of the sewage suction pipe 1. When the metal pipe 2 and the internally threaded pipe 21 enter the sewer pipe, the weight of the metal pipe 2, the internally threaded pipe 21 and the parts connected thereto can drive one end of the sewage suction pipe 1 to continue to automatically descend. As the silt continues to decrease, the metal pipe 2 and the internally threaded pipe 21 will continue to rely on their own weight to drive one end of the sewage suction pipe 1 to descend, so that the internally threaded pipe 21 is always located above the silt. In the mud, during the sewage suction process, the silt will enter the internal threaded tube 21 and spirally rise along the thread of the inner wall of the internal threaded tube 21. When the silt passes through the blade 24, the blade 24 cuts the foreign matter in the silt and reduces its volume. As the silt enters the sewage suction pipe 1, it is transported to the silt collection equipment. During this process, if there are harder foreign matters such as stones in the silt and they hit the blade 24, the blade 24 will be hit and the buffer spring 25 will contract to provide buffer protection for the blade 24.

[0037] Combined with attachment Figure 1 、 Figure 2 and Figure 3 As shown, the metal tube 2 is provided with a plurality of fixedly connected telescopic rods 3, one end of the telescopic rod 3 is rotatably mounted with a pulley 31, a spring is provided inside the telescopic rod 3, and the bottom of the telescopic rod 3 is fixedly connected to the sleeve plate 4 through a frame.

[0038] Furthermore, four telescopic rods 3 are provided. When the sewage suction pipe 1 is placed into the sewer pipe, the telescopic rod 3 is first compressed so that the total length of the two opposite telescopic rods 3 is less than the diameter of the sewer pipe to be cleaned, ensuring that the telescopic rod 3 can be placed into the sewer pipe. When the telescopic rod 3 enters the sewer pipe, the telescopic rod 3 is released. At this time, the spring in the telescopic rod 3 rebounds, the telescopic rod 3 extends, and the pulley 31 rests on the inner wall of the sewer pipe. The telescopic rod 3 limits the sewage suction pipe 1, so that the sewage suction pipe 1 can be stably located in the middle position of the sewer pipe during operation. At the same time, the pulley 31 can reduce the friction between the sewage suction pipe 1 and the inner wall of the sewer pipe, making it easier for the sewage suction pipe 1 to descend and rise.

[0039] Combined with attachment Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, the lower part of the telescopic rod 3 is fixedly connected to the sleeve plate 4, and the sleeve plate 4 is slidably connected to the inner plate 41. The inner plate 41 is clamped with an arc plate 42. A limiting mechanism 43 is provided between the sleeve plate 4 and the inner plate 41. The limiting mechanism 43 includes a mounting seat 431, a receiving groove 432, a limiting strip 433, a limiting spring 1 434, a limiting plate 435 and a limiting spring 2 436. The inner plate 41 is fixedly connected to the mounting seat 431, and a receiving groove 432 is provided on one side of the mounting seat 431. The sliding connection Connected to the limit strip 433, a plurality of limit springs 434 are provided between the lower portion of the limit strip 433 and the inner bottom wall of the receiving groove 432. The inner top wall of the sleeve plate 4 is rotatably connected to the limit plate 435 through a support rod. The bottom side of the limit plate 435 and the limit strip 433 are staggered and engaged with each other. A plurality of limit springs 436 are provided between the top of the limit plate 435 and the inner top wall of the sleeve plate 4. A plurality of fixing springs 44 are provided between the sleeve plate 4 and the inner plate 41. The fixing springs 44 are evenly distributed on both sides of the limit mechanism 43.

[0040] The top of the sleeve plate 4 is fixedly connected to a mounting box 5, and a motor 51 is fixedly connected inside the mounting box 5. The output end of the motor 51 is wound with a traction rope 52 through an axis rod. One end of the traction rope 52 passes through the sleeve plate 4 and is fixedly docked with the top of the limit plate 435.

[0041] Furthermore, there are four sleeve plates 4, which are respectively arranged around the metal pipe 2. The arc plates 42 on the two adjacent sleeve plates 4 are installed in an upper and lower staggered manner. Before sucking sewage, the arc plates 42 of appropriate size are replaced according to the diameter of the sewer pipe, and then the inner plate 41 is pressed to shrink the inner plate 41 into the sleeve plate 4 and squeeze and shrink the fixing spring 44. In the process of the inner plate 41 moving into the sleeve plate 4, the limit bar 433 and the limit plate 435 are squeezed. Since the top side of the limit bar 433 is a slope, after the limit bar 433 contacts the limit plate 435, the lateral pressure applied by the limit plate 435 to the limit bar 433 will be converted into vertical pressure by the slope on the limit bar 433, and the limit spring 434 below the limit bar 433 is squeezed. After that, the limit strip 433 contracts and retracts into the receiving groove 432. When the limit strip 433 moves to the other side of the limit plate 435, the extrusion force on the limit strip 433 disappears, and the limit spring 434 rebounds, causing the limit strip 433 to pop out. At this time, the limit strip 433 and the limit plate 435 are in a state of being clamped to each other, thereby completing the limitation of the inner plate 41. Later, when the internal threaded pipe 21 enters the silt, the sleeve plate 4 and the inner plate 41 will fit the silt surface. At this time, the sleeve plate 4 and the inner plate 41 cooperate to increase the contact area with the silt, reduce the pressure, float on the surface of the silt, complete the limitation of the metal pipe 2 and the internal threaded pipe 21, and prevent the sewage suction pipe 1 from entering the silt, causing the silt to squeeze the sewage suction pipe 1 and shrink, thereby affecting the silt absorption efficiency;

[0042] The installation box 5 is provided with a lithium battery and a control element. When the sewage suction work is completed, the motor 51 is controlled to rotate through remote control. During the rotation process, the motor 51 reels the traction rope 52. During the retraction process, the traction rope 52 lifts one end of the limit plate 435 and uses the rotating limit plate 435 to stretch the limit spring 2 436. At this time, after one end of the limit plate 435 is lifted, the limit of the limit bar 433 disappears. At this time, the fixed spring 44 rebounds, driving the inner plate 41 to extend until the arc plate 42 fits in the sewer pipe. On the wall, turn off the motor 51, and the motor 51 has no locking structure. At this time, the limit spring 2 436 rebounds, driving the limit plate 435 to reset. During the reset process, the limit plate 435 drives the output end of the motor 51 to rotate in the opposite direction through the traction rope 52 until it returns to its original state. At this time, when the sewage suction pipe 1 is retracted, the arc plate 42 scrapes and collects the silt on the inner wall of the sewer pipe, and after the arc plate 42 is retracted to the ground, the silt on the arc plate 42 is collected and processed, and then a small amount of silt on the inner wall of the sewer pipe is high-pressure cleaned.

[0043] Combined with attachment Figure 1 and Figure 11 As shown, a load-bearing frame 6 is provided below the sewage suction pipe 1, and two rotatably connected winding drums 62 are provided on the load-bearing frame 6, and a load-bearing rope 63 is wound on the winding drum 62. The bottom ends of the load-bearing rope 63 are respectively fixedly connected to the tops of any two adjacent sleeve plates 4, and a winding rod 61 is rotatably connected to the load-bearing frame 6. The winding rod 61 is located between the winding drums 62, and the winding rod 61 is located below the sewage suction pipe 1. The load-bearing frame 6 and the winding drum 62 are connected by a coupling, the load-bearing frame 6 is rotatably connected to the coupling, the winding drum 62 is fixedly connected to the coupling, and the winding drum 62 and the winding rod 61 are fixedly docked. A handle 64 is rotatably connected to one side of the load-bearing frame 6, and the handle 64 is fixedly docked with the coupling on the load-bearing frame 6.

[0044] Furthermore, the sewage suction pipe 1 is placed on the winding rod 61, and the rotatable winding rod 61 is used to reduce the friction between the sewage suction pipe 1, so that the metal pipe 2 drives one end of the sewage suction pipe 1 to descend by relying on its weight. During the descent of the metal pipe 2, the load-bearing rope 63 limits the balance of the four sleeves 4, so that the four sleeves 4 are all in a horizontal state and fit on the silt surface, which can better provide limiting support for the metal pipe 2. After the sewage suction work is completed, turn the handle 64 and use the winding disc 62 to reel in the load-bearing rope 63 to remove the sewage suction pipe 1 from the sewer pipe. Since the winding rod 61 is a rotatable structure, the friction on the outer wall of the sewage suction pipe 1 is reduced during the retraction of the sewage suction pipe 1, thereby providing certain protection for the sewage suction pipe 1, and at the same time making it more convenient for the metal pipe 2 and the internal threaded pipe 21 to drive the sewage suction pipe 1 to descend by relying on their own weight.

[0045] Working principle:

[0046] Place the sewage suction pump 11 at the designated location, set up the load-bearing frame 6, connect the output end of the sewage suction pump 11 to the external pipe, connect the external pipe to the sludge collection equipment, place one end of the sewage suction pipe 1 on the winding rod 61, fix the load-bearing rope 63 to the top of each sleeve plate 4, and then install the appropriate arc plate 42 on the inner plate 41 according to the diameter of the sewer pipe, and start preparing for sewage suction work.

[0047] Before sucking dirt, press the inner plate 41 to make it retract into the sleeve plate 4, squeeze and shrink the fixing spring 44. In the process of the inner plate 41 moving into the sleeve plate 4, the limit bar 433 and the limit plate 435 are squeezed. Since the top side of the limit bar 433 is an inclined surface, after the limit bar 433 contacts the limit plate 435, the lateral pressure applied by the limit plate 435 to the limit bar 433 is converted into vertical pressure on the inclined surface of the limit bar 433. At this time, the limit spring 434 below the limit bar 433 is squeezed and shrinks, so that the limit bar 43 3 is retracted into the receiving groove 432. When the limiting strip 433 moves to the other side of the limiting plate 435, the squeezing force on the limiting strip 433 disappears, and the limiting spring 434 rebounds, popping out the limiting strip 433. At this time, the limiting strip 433 and the limiting plate 435 are clamped with each other, completing the limitation of the inner plate 41. Then, the telescopic rod 3 is compressed so that the total length of the two opposing telescopic rods 3 is less than the diameter of the sewer pipe to be cleaned, ensuring that the telescopic rod 3 can be placed in the sewer pipe. Then, the metal pipe 2 and the internal threaded pipe 21 are placed in the sewer pipe.

[0048] When the telescopic rod 3 enters the sewer pipe, the telescopic rod 3 is released, and the spring inside the telescopic rod 3 rebounds, causing the telescopic rod 3 to extend. After the telescopic rod 3 is extended, the pulley 31 is against the inner wall of the sewer pipe, and the telescopic rod 3 is used to limit the sewage suction pipe 1 so that the sewage suction pipe 1 is stably located in the middle position of the sewer pipe during operation. When the metal pipe 2 and the internally threaded pipe 21 enter the sewer pipe, the weight of the metal pipe 2 and the internally threaded pipe 21 is used to drive one end of the sewage suction pipe 1 to continue to descend. When the internally threaded pipe 21 enters the silt, the sleeve plate 4 and the inner plate 41 will fit on the surface of the silt. Due to the cooperation between the sleeve plate 4 and the inner plate 41, the contact area with the silt is increased, the pressure is reduced, and it floats on the surface of the silt, completing the limitation of the metal pipe 2 and the internally threaded pipe 21.

[0049] Then turn on the sewage suction pump 11, and the sludge in the sewer pipe first enters the internal threaded pipe 21 and spirally rises along the threads of the inner wall of the internal threaded pipe 21. When the sludge passes through the blade 24, the blade 24 cuts the foreign matter in the sludge into smaller foreign matter, which enters the sewage suction pipe 1 together with the sludge and is transported to the sludge collection equipment. During this process, if there are harder foreign matter such as stones in the sludge and they hit the blade 24, the buffer spring 25 contracts to provide buffering protection for the blade 24, and the sludge flows along the sewage suction pipe 1 and the sewage suction pump 11 into the sludge collection equipment for temporary storage.

[0050] As the sludge is absorbed, the sludge level in the sewer pipe decreases. During this process, one end of the sewage suction pipe 1 is pulled by the weight of the metal pipe 2 and continues to drop, so that the internal threaded pipe 21 always remains in the sludge.

[0051] When the silt in the sewer pipe is completely absorbed, the motor 51 is controlled to rotate through remote control to reel in the traction rope 52. During the reeling process, the traction rope 52 can lift one end of the limit plate 435 and use the rotating limit plate 435 to stretch the limit spring 2 436. After one end of the limit plate 435 is lifted, the limit of the limit bar 433 disappears, and the fixed spring 44 rebounds, driving the inner plate 41 to extend until the arc plate 42 fits against the inner wall of the sewer pipe. Then the motor 51 is turned off. The motor 51 has no locking structure. At this time, the limit spring 2 436 rebounds, driving the limit plate 435 to reset. During the resetting process, the limit plate 435 drives the output end of the motor 51 to rotate in the opposite direction through the traction rope 52 until it returns to its original state. Then the handle 64 is turned, and the reel 62 reels the load-bearing rope 63 to take the sewage suction pipe 1 out of the sewer pipe. When the sewage suction pipe 1 is retracted, the arc plate 42 scrapes and collects the silt on the inner wall of the sewer pipe. After the arc plate 42 is retracted to the ground, the silt on the arc plate 42 is collected and processed, and then the small amount of silt on the inner wall of the sewer pipe is cleaned with high pressure.

[0052] Finally, clean the internal threaded pipe 21, the metal pipe 2, the sewage suction pipe 1 and the inside of the sewage suction pump 11 with clean water, and at the same time clean the sludge attached to the surface of the device to facilitate next use.
