Description

Technical Field

[0001] The present application relates to the field of pipeline transportation, and in particular to an anti-crystallization reverse pipe structure of a manure liquid transportation pipe. Background Art

[0002] The manure field needs to process pig manure liquid, which mainly includes excrement and urine, so it contains a large amount of water, organic matter and inorganic matter. In the existing related technology, the pig manure liquid needs to be transported to the liquid storage tank through the sewage pipe to facilitate the treatment of the pig manure liquid.

[0003] With regard to the above-mentioned related technologies, the side wall of the pipe opening of the sewage pipe is prone to crystallization after long-term transportation of pig manure liquid. The crystallization will block the pipe opening of the sewage pipe and affect the transportation efficiency of the pig manure liquid. Summary of the invention

[0004] In order to prevent the pipe opening of the sewage pipe from being easily crystallized due to long-term transportation of pig manure liquid, the present application provides an anti-crystallization reverse pipe structure of the manure liquid transportation pipe.

[0005] The anti-crystallization reverse pipe structure of the manure liquid conveying pipe provided in this application adopts the following technical solutions:

[0006] A crystallization-proof reverse pipe structure for a manure conveying pipe comprises a sewage pipe, an adjusting cone head and a driving assembly. The pipe mouth of the sewage pipe is bent upward, the adjusting cone head is located at the top of the sewage pipe, and the end of the adjusting cone head with a small diameter is arranged in a vertical direction toward the pipe mouth of the sewage pipe. The driving assembly is used to drive the adjusting cone head to move vertically toward or away from the pipe mouth of the sewage pipe.

[0007] By adopting the above technical solution, the outlet of the sewage pipe is arranged upward, so that the pig manure liquid first needs to flow upward to the outlet of the sewage pipe, then flow through the side wall of the outlet of the sewage pipe, and finally flow down from the side wall of the outlet of the sewage pipe. The pig manure liquid flows and flushes the side wall of the outlet of the sewage pipe for a long time, so that the pig manure liquid is not easy to crystallize on the side wall of the outlet of the sewage pipe, and then the outlet of the sewage pipe is not easy to be blocked by crystallization, which is conducive to ensuring the transportation efficiency of the pig manure liquid.

[0008] When crystals appear on the side wall of the sewage pipe's mouth or the sewage pipe carries less pig manure liquid, the driving assembly drives the adjusting cone head to move toward the mouth of the sewage pipe, thereby reducing the flow area of ​​the sewage pipe's mouth, thereby accelerating the flow rate of the pig manure liquid and ensuring the flushing effect of the crystals when the pig manure liquid flows.

[0009] Optionally, the drive assembly includes an outer shell, an internal threaded tube and a transmission screw, the internal threaded tube is rotatably fitted with the outer shell, the internal threaded tube is arranged in a vertical direction, the transmission screw is threadably fitted with the internal threaded tube, and the adjusting cone head is fixedly installed at the bottom of the transmission screw.

[0010] By adopting the above technical solution, the internal threaded tube is rotated to drive the transmission screw to move in the vertical direction, thereby driving the adjusting cone head to move vertically toward or away from the pipe mouth of the sewage pipe, thereby changing the flow area of ​​the pipe mouth of the sewage pipe. The structure is simple, stable and corrosion-resistant.

[0011] Optionally, the internal threaded tube is coaxially fixed with a worm gear, the outer shell is rotatably matched with a worm, the worm is meshed with the worm gear, and a hand wheel is coaxially fixedly mounted on the worm.

[0012] By adopting the above technical solution, the operator turns the handwheel to drive the worm to rotate, and the rotation of the worm drives the worm wheel to rotate, which in turn drives the internal threaded pipe to rotate, thereby driving the transmission screw to move in the vertical direction, so that the flow area of ​​the pipe mouth of the sewage pipe can be changed according to the height position of the adjusting cone head.

[0013] Due to the self-locking between the worm wheel and the worm, the adjusting cone head is not easy to drive the transmission screw and the internal threaded pipe to rotate under the long-term scouring effect of pig manure liquid, which is beneficial to the long-term adjustment of the height size of the cone head.

[0014] In addition, due to the rotation between the worm wheel and the worm, the hand wheel faces the operator at a more appropriate angle, making it easier for the operator to drive the hand wheel to adjust the cone head to move vertically toward or away from the pipe mouth of the sewage pipe.

[0015] In addition, there is a speed reduction between the worm wheel and the worm, which allows the operator to adjust the height position of the adjusting cone head with higher precision, reducing the occurrence of excessive vertical movement distance of the adjusting cone head due to excessive rotation angle of the hand wheel caused by the operator's hand tremor.

[0016] Optionally, a receiving chamber is provided inside the housing, and the worm wheel and the worm are both located in the receiving chamber.

[0017] By adopting the above technical solution, the gap between the worm wheel and the worm is not easy to accumulate dirt due to rain erosion or gas emitted by pig manure, which is conducive to ensuring the long-term use of the worm wheel and the worm.

[0018] Optionally, the outer shell is installed on an external wall through an installation bracket, and the installation bracket includes a connecting plate, a bearing plate and a triangular plate. The connecting plate is fixed to the external wall by bolts, and the bearing plate is fixedly installed on the connecting plate. The bearing plate is arranged in a horizontal direction, and the two sides of the triangular plate are respectively fixedly installed on the connecting plate and the bearing plate, and the outer shell is fixedly installed on the top of the bearing plate.

[0019] By adopting the above technical solution, the triangular plate increases the connection strength between the bearing plate and the connecting plate, which is beneficial to ensure the installation stability of the shell.

[0020] Optionally, a cavity is provided inside the adjusting cone head.

[0021] By adopting the above technical solution, the cavity reduces the weight of the adjusting cone head, which is conducive to reducing the difficulty of vertically moving the adjusting cone head toward or away from the pipe mouth of the sewage pipe through the driving component.

[0022] Optionally, the diameter of the end with a larger diameter of the adjusting cone head is larger than the inner diameter of the pipe opening of the sewage pipe.

[0023] The adoption of the above technical solution is conducive to ensuring the adjustment range of the flow area of ​​the pipe mouth of the sewage pipe by the adjusting cone head, so that the pipe mouth of the sewage pipe can be infinitely adjusted between fully open and fully closed.

[0024] Optionally, the pipe mouth of the sewage pipe is provided with a chamfer, and the chamfer is arranged in a nearly arc shape.

[0025] By adopting the above technical solution, the chamfer reduces the resistance encountered by the pig manure liquid flowing through the pipe mouth of the sewage pipe, thereby making it difficult for the pig manure liquid to crystallize on the side wall of the pipe mouth of the sewage pipe, thereby making it difficult for the pipe mouth of the sewage pipe to be blocked by crystallization, which is beneficial to ensuring the transportation efficiency of the pig manure liquid.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The outlet of the sewage pipe is set upward, so that the pig manure liquid first needs to flow upward to the outlet of the sewage pipe, then flow through the side wall of the outlet of the sewage pipe, and finally flow down from the side wall of the outlet of the sewage pipe. The pig manure liquid flows and flushes the side wall of the outlet of the sewage pipe for a long time, making it difficult for the pig manure liquid to crystallize on the side wall of the outlet of the sewage pipe, and then making the outlet of the sewage pipe not easily blocked by crystallization, which is conducive to ensuring the transportation efficiency of the pig manure liquid.

[0028] When crystals appear on the side wall of the sewage pipe's mouth or the sewage pipe carries less pig manure liquid, the driving assembly drives the adjusting cone head to move toward the mouth of the sewage pipe, thereby reducing the flow area of ​​the sewage pipe's mouth, thereby accelerating the flow rate of the pig manure liquid and ensuring the flushing effect of the crystals when the pig manure liquid flows.

[0029] 2. Rotate the internal threaded tube to drive the transmission screw to move in the vertical direction, thereby driving the adjusting cone head to move vertically toward or away from the pipe mouth of the sewage pipe, thereby changing the flow area of ​​the pipe mouth of the sewage pipe. The structure is simple, stable and corrosion-resistant.

[0030] 3. The operator turns the handwheel to drive the worm, and the rotation of the worm drives the worm wheel, which in turn drives the internal threaded pipe to rotate, thereby driving the transmission screw to move in the vertical direction, so that the flow area of ​​the pipe mouth of the sewage pipe can be changed according to the height position of the adjusting cone head.

[0031] Due to the self-locking between the worm wheel and the worm, the adjusting cone head is not easy to drive the transmission screw and the internal threaded pipe to rotate under the long-term scouring effect of pig manure liquid, which is beneficial to the long-term adjustment of the height size of the cone head.

[0032] In addition, due to the rotation between the worm wheel and the worm, the hand wheel faces the operator at a more appropriate angle, making it easier for the operator to drive the hand wheel to adjust the cone head to move vertically toward or away from the pipe mouth of the sewage pipe.

[0033] In addition, there is a speed reduction between the worm wheel and the worm, which allows the operator to adjust the height position of the adjusting cone head with higher precision, reducing the occurrence of excessive vertical movement distance of the adjusting cone head due to excessive rotation angle of the hand wheel caused by the operator's hand tremor.

[0041] Reference Figure 1 The regulating cone head 2 is located at the top of the pipe mouth of the sewage pipe 1, and the end of the regulating cone head 2 with a small diameter, that is, the bottom, is arranged toward the pipe mouth of the sewage pipe 1 in the vertical direction, and the end of the regulating cone head 2 with a large diameter, that is, the top, is arranged away from the pipe mouth of the sewage pipe 1 in the vertical direction, so as to change the depth of the bottom of the regulating cone head 2 entering the pipe mouth of the sewage pipe 1, change the flow area of ​​the sewage pipe 1, and then adjust the flow rate of the pig manure liquid according to the delivery amount of the pig manure liquid, thereby ensuring the flushing effect of the pig manure liquid on the pipe mouth of the sewage pipe 1.

[0042] Reference Figure 1 The diameter of the top of the adjusting cone head 2 is larger than the inner diameter of the pipe opening of the sewage pipe 1, so that the pipe opening of the sewage pipe 1 can be infinitely adjusted between fully open and fully closed. A cavity 201 is provided inside the adjusting cone head 2. In addition, a cavity 201 is provided inside the adjusting cone head 2 to reduce the weight of the adjusting cone head 2, thereby reducing the difficulty of vertically moving the adjusting cone head 2 toward or away from the pipe opening of the sewage pipe 1.

[0047] The implementation principle of the anti-crystallization anti-tube structure of the manure liquid conveying pipe of the embodiment of the present application is: when the pig manure liquid is discharged from the pipe mouth of the sewage pipe 1, it will flush the side wall of the pipe mouth of the sewage pipe for a long time, so that the pig manure liquid is not easy to crystallize on the side wall of the pipe mouth of the sewage pipe 1, and then the pipe mouth of the sewage pipe 1 is not easy to be blocked by crystallization, which is conducive to ensuring the transportation efficiency of the pig manure liquid. In addition, the internal threaded pipe 32 is driven to rotate by the hand wheel 5, so that the transmission screw 33 drives the adjustment cone head 2 to move vertically in the direction close to or away from the pipe mouth of the sewage pipe 1, and then the flow area of ​​the pipe mouth of the sewage pipe 1 can be changed according to the conveying amount of the pig manure liquid, thereby ensuring that the flow rate of the pig manure liquid is always sufficient to flush the side wall of the pipe mouth of the sewage pipe 1, reducing the generation of crystals.
