Description

Technical Field

[0001] The present application relates to the technical field of pipeline structures, and in particular to a convenient and practical sewage discharge pipeline. Background Art

[0002] Traditionally, sewage discharge is usually handled by underground drainage pipe networks in homes, industries and public places. However, since underground drainage pipes are often hidden underground, once they encounter blockages or other problems, the discharged sewage is difficult to find and repair in time, resulting in sewage stagnation and accumulation, thereby increasing the risk of environmental pollution. Utility Model Content

[0003] In order to reduce the probability of blockage of the sewage pipe and the difficulty of cleaning impurities in the sewage pipe, the present application provides a convenient and practical sewage pipe.

[0004] The present application provides a convenient and practical sewage pipe, which adopts the following technical solution:

[0005] A convenient and practical sewage pipe comprises an inner pipe and a shell sleeved outside the inner pipe, two adjacent sections of the inner pipe are connected to each other through the shell, and a filtering mechanism for filtering sewage flowing through the inner pipe is provided on the shell, and the filtering mechanism comprises:

[0006] A coarse filter, wherein the coarse filter is arranged in the housing;

[0007] A fine filter screen is arranged in the housing, and the sewage first passes through the coarse filter screen into the housing and then passes through the fine filter screen;

[0008] A sealing cover, wherein the shell is provided with a through hole communicating with the interior of the shell, and the sealing cover is detachably connected to the shell through a connecting assembly and covers the through hole;

[0009] A cleaning component is arranged on the shell and is used for cleaning impurities on the coarse filter and the fine filter.

[0010] By adopting the above technical solution, when sewage flows from one inner tube to another inner tube, the sewage first passes through the coarse filter, which filters out large-particle impurities in the sewage. The sewage filtered by the coarse filter enters the shell and then passes through the fine filter, which filters out small-particle impurities in the sewage. Thus, the impurities in the sewage are filtered out by the cooperation of the coarse filter and the fine filter, and the large-particle and small-particle impurities are filtered out separately, thereby reducing the probability of impurities directly clogging the filter. At the same time, the impurities adhering to the coarse filter and the fine filter can be cleaned by opening the sealing cover and using the cleaning component, thereby reducing the probability of impurities directly clogging the filter and ensuring the use effect of the coarse filter and the fine filter.

[0011] Optionally, the cleaning component includes:

[0012] A water storage pipe, the water storage pipe is arranged on the housing, and the water part after passing through the fine filter is stored in the water storage pipe;

[0013] Two flushing pipes, both of which are arranged on the shell and are connected to the water storage pipe, and the water outlets of the two flushing pipes are respectively directed toward the coarse filter and the fine filter to filter out impurities in the sewage;

[0014] A flushing water pump is arranged on the water storage pipe and is communicated with the inside of the water storage pipe. The flushing water pump is used to draw water in the water storage pipe into the two flushing water pipes.

[0015] By adopting the above technical scheme, the clean water filtered by the coarse filter and the fine filter enters the water storage pipe for storage. When the sealing cover is opened to clean the impurities adhered to the surface of the coarse filter and the fine filter, the flushing pump starts to draw water in the water storage pipe into the two flushing pipes. The two flushing pipes flush the surface of the coarse filter and the fine filter respectively, and the impurities adhered to the surface of the coarse filter and the fine filter are flushed out through the through holes, thereby completing the cleaning of the impurities adhered to the coarse filter and the fine filter.

[0016] Optionally, the connection component includes:

[0017] A first connecting ring, wherein the first connecting ring is arranged on the housing;

[0020] By adopting the above technical solution, the connecting screw is twisted to disengage from the first connecting ring, and the second connecting ring can be moved to disengage from the first connecting ring, so that the sealing cover is removed to clean the impurities in the shell. After the cleaning is completed, the second connecting ring is moved to press against the first connecting ring, and the connecting screw is moved to pass through the connecting hole and threadedly connected to the threaded hole, thereby completing the disassembly and fixing work between the sealing cover and the shell.

[0021] Optionally, pressure sensors are provided on both sides of the coarse filter and both sides of the fine filter, and a controller is provided on the shell, and the controller is electrically connected to the pressure sensors and the flushing pump.

[0022] By adopting the above technical solution, pressure sensors are set on both sides of the coarse filter and the fine filter, so that the degree of blockage of impurities on the coarse filter and the fine filter can be grasped by testing the water pressure on both sides of the fine filter and the coarse filter. When the water pressure difference on both sides of the fine filter and the coarse filter reaches the limit value, the controller controls the flushing pump to start flushing the impurities on the coarse filter and the fine filter, thereby reducing the probability of impurity blockage of the coarse filter and the fine filter.

[0023] Optionally, a flow regulating valve is provided on one end of the inner tube close to the coarse filter, and the flow regulating valve is electrically connected to the controller. A switch valve is provided on one end of the inner tube close to the fine filter.

[0024] By adopting the above technical solution, a flow regulating valve and a switch valve are set on the inner pipe. When the controller controls the flushing pump to start, the controller controls the flow regulating valve to reduce the flow of sewage entering the shell, thereby facilitating the two flushing pipes to flush the coarse filter and the fine filter.

[0025] Optionally, the flushing pipe opening is provided with a nozzle, and a plurality of water dispersion holes are evenly distributed on the nozzle.

[0027] Optionally, a rubber ring is provided on the sealing cover, and the rubber ring extends into the through hole and presses against the inner wall of the through hole.

[0028] By adopting the above technical solution, when the sealing cover covers the through hole, the rubber ring extends into the through hole and presses against the inner wall of the through hole, thereby sealing the sealing cover and the through hole, thereby improving the sealing performance of the sealing cover on the through hole.

[0029] Optionally, the inner tube is coated with a thermal insulation cotton layer.

[0030] By adopting the above technical solution, a thermal insulation cotton layer is coated on the outside of the inner pipe, thereby reducing the probability of sewage in the inner pipe freezing when the outdoor temperature is low, reducing the probability of the inner pipe being frozen and cracked, and increasing the service life of the inner pipe.

[0032] 1. The coarse filter screen is used to filter out large-size impurities in the sewage, and the fine filter screen is used to filter out small-size impurities in the sewage. Thus, the coarse filter screen and the fine filter screen are used to filter out impurities in the sewage, and the large-size and small-size impurities are filtered out separately, thereby reducing the probability of impurities directly clogging the filter screen. At the same time, the impurities adhering to the coarse filter screen and the fine filter screen can be cleaned by opening the sealing cover and using the cleaning component, thereby reducing the probability of impurities directly clogging the filter screen and ensuring the use effect of the coarse filter screen and the fine filter screen;

[0033] 2. By setting pressure sensors on both sides of the coarse filter and the fine filter, the degree of blockage of impurities on the coarse filter and the fine filter can be mastered by testing the water pressure on both sides of the fine filter and the coarse filter. When the water pressure difference on both sides of the fine filter and the coarse filter reaches the limit value, the controller controls the flushing pump to start flushing the impurities on the coarse filter and the fine filter, thereby reducing the probability of impurity blockage on the coarse filter and the fine filter;

Two adjacent sections of the inner tube 11 are connected to each other through the shell 12, and the shell 12 is provided with a filtering mechanism 2 for filtering the sewage flowing through the inner tube 11.

[0041] Reference Figure 1 and Figure 2 The filter mechanism 2 includes a coarse filter 21, a fine filter 22, a sealing cover 23 and a cleaning assembly 24. The coarse filter 21 and the fine filter 22 are both arranged in the housing 12. The sewage in the inner tube 11 first enters the housing 12 and then passes through the coarse filter 21 and then the fine filter 22. A vertical through hole is provided on the bottom wall of the housing 12 below the coarse filter 21 and the fine filter 22. The sealing cover 23 is detachably connected to the bottom wall of the housing 12 through the connecting assembly 4 and covers the through hole.

[0042] Reference Figure 1 and Figure 2 The cleaning assembly 24 is used to clean the impurities adhered to the coarse filter 21 and the fine filter 22. The cleaning assembly 24 includes a water storage pipe 31, two flushing pipes 32 and a flushing pump 33. The water storage pipe 31 is fixedly connected to the outer wall of the shell 12. A water pipe 34 is fixedly connected to the side wall of the water storage pipe 31 close to the shell 12. The water pipe 34 is connected to the inside of the shell 12 on the side of the fine filter 22 away from the coarse filter 21. A check valve is fixedly connected to the water pipe 34. The water in the shell 12 that has been filtered by the fine filter 22 is stored in the water storage pipe 31 through the water pipe 34.

[0043] Reference Figure 1 and Figure 2 One end of the two flushing pipes 32 is fixedly connected to the outer wall of the water storage pipe 31 and communicated with the inside of the water storage pipe 31. The other ends of the two flushing pipes 32 pass through the top wall of the shell 12 and extend into the inside of the shell 12, and the water outlets are arranged toward the coarse filter 21 and the fine filter 22. A nozzle is fixedly connected to the water outlet of the flushing pipe 32, and a plurality of water dispersion holes are evenly distributed on the nozzle. The flushing pump 33 is fixedly connected to the flushing pipe 32 and communicated with the inside of the flushing pipe 32.

[0044] Reference Figure 1 and Figure 2 The housing 12 on both sides of the fine filter 22 and the coarse filter 21 is fixedly connected with a pressure sensor 13, and the upper surface of the housing 12 is fixedly connected with a controller 14 electrically connected to the pressure sensor 13. The end of the inner tube 11 close to the coarse filter 21 is fixedly connected with a flow regulating valve 15, and the flow regulating valve 15 is electrically connected to the controller 14. The end of the inner tube 11 close to the fine filter 22 is provided with a switch valve 16.

[0045] Reference Figure 1 and Figure 2After the sewage enters the shell 12 through the inner tube 11, it is first filtered by the coarse filter 21. The coarse filter 21 filters out large-size impurities in the sewage. The filtered water is then filtered by the fine filter 22. The fine filter 22 filters out small-size impurities in the water. The water double-filtered by the coarse filter 21 and the fine filter 22 enters the next inner tube 11 for discharge, and part of the water filtered by the fine filter 22 enters the water storage pipe 31 for storage.

[0046] Reference Figure 1 and Figure 2 When the coarse filter 21 and the fine filter 22 are used for a long time, the surface is clogged by a large amount of impurities, so that the water pressure on both sides of the fine filter 22 and the coarse filter 21 produces a water pressure difference. After the pressure sensor 13 senses the water pressure difference, it converts the water pressure difference into an electrical signal and transmits it to the controller 14. The controller 14 controls the flow regulating valve 15 to reduce the discharge flow of sewage, and then the flushing pump 33 is started to flush the surface of the fine filter 22 and the coarse filter 21 through the flushing pipe 32, and the impurities adhering to and blocking the coarse filter 21 and the fine filter 22 are brushed off. The impurities can be cleaned by opening the sealing cover 23 through the connecting component 4.

When the second connecting ring 42 contacts the first connecting ring 41, the second connecting ring 42 is provided with connecting holes corresponding to the threaded holes. The connecting screw 43 passes through the connecting holes and is threadedly connected to the threaded holes.

[0048] Reference Figure 1 and Figure 2 A rubber ring 25 is fixedly connected to a side wall of the sealing cover 23 close to the housing 12. When the sealing cover 23 covers the through hole, the rubber ring 25 extends into the through hole and presses against the inner wall of the through hole.

[0049] The working principle of the embodiment of the present application is as follows:

[0050] After the sewage enters the housing 12 through the inner pipe 11, it is first filtered by the coarse filter 21, which filters out large-size impurities in the sewage. The filtered water is then filtered by the fine filter 22, which filters out small-size impurities in the water. The water after double filtration by the coarse filter 21 and the fine filter 22 enters the next inner pipe 11 for discharge. When the coarse filter 21 and the fine filter 22 are used for a long time, the surface is blocked by a large amount of impurities, so that the water pressure on both sides of the fine filter 22 and the coarse filter 21 produces a water pressure difference. After the pressure sensor 13 senses the water pressure difference, it converts the water pressure difference into an electrical signal and transmits it to the controller 14. The controller 14 controls the flow regulating valve 15 to reduce the discharge flow of the sewage, and then the flushing pump 33 is started to flush the surface of the fine filter 22 and the coarse filter 21 through the flushing pipe 32, and the impurities adhering to and blocking the coarse filter 21 and the fine filter 22 are brushed off. The impurities can be cleaned by opening the sealing cover 23.
