Description

Technical Field

[0001] This utility model belongs to the field of drainage equipment technology, and in particular relates to a double-pipe sludge discharge structure. Background Technology

[0002] Municipal pipe networks extensively utilize drainage equipment to discharge wastewater, including domestic wastewater and rainwater. This water is mostly untreated and carries sludge along with it, which accumulates at the bottom of the drainage equipment, forming mud. To prevent blockages, existing drainage systems typically include a sludge discharge structure at the bottom. This usually consists of one or more horizontally arranged sludge discharge pipes with discharge holes. When a significant amount of sludge accumulates inside the drainage equipment, a suction device connected to the discharge pipe outlet is activated to remove the sludge from the bottom of the equipment through the discharge holes, thus circulating the system to clean the sludge at the bottom.

[0003] However, in the current application of sludge discharge pipes, blockages will occur in the sludge discharge pipes over time. This is mainly because large particles and debris in the sludge will accumulate in the pipe, reducing the effective cross-sectional area of ​​the pipe, hindering the flow of sludge, affecting the smooth discharge of sludge, and making it easy for bacteria and microorganisms to grow, further reducing water quality. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a double-pipe sludge discharge structure to improve the dredging efficiency of the sludge discharge pipe and improve the blockage situation of the sludge discharge pipe during long-term use.

[0005] The technical solution adopted by this utility model to solve its technical problem is: to provide a double-sleeve sludge discharge structure, including a sludge discharge pipe installed at the lower part of the sludge collection hopper of the drainage equipment, the surface of the sludge discharge pipe having a plurality of sludge discharge holes, a sleeve provided inside the sludge discharge pipe, the sleeve being located at the lower part inside the sludge discharge pipe, and a plurality of water distribution holes being opened on the sleeve.

[0006] Preferably, the sludge discharge holes are arranged in a linear array along the length of the sludge discharge pipe.

[0007] Preferably, the water distribution holes are arranged in a linear array along the length of the sleeve.

[0008] Preferably, the number of sleeves is set according to the ratio of the inner diameter of the sludge discharge pipe to the inner diameter of the sleeve.

[0009] Preferably, the sludge discharge pipe is arranged at an angle downwards toward its outlet.

[0010] Preferably, the slope angle between the sludge discharge pipe and the bottom surface of the sludge collection hopper is 1 to 5°.

[0011] Preferably, the sleeve is arranged at an angle downwards toward its outlet direction.

[0012] The beneficial effects are as follows: The lower part of the sludge discharge pipe of this utility model is equipped with a sleeve, which has several water distribution holes. When the sludge discharge pipe and the water distribution pipe are opened, sludge is discharged simultaneously, allowing for rapid discharge of muddy water or slurry, shortening the sludge discharge time, saving drainage volume, and improving the sludge discharge effect. The slope angle between the sludge discharge pipe and the bottom surface of the sludge collection hopper is 1–5°, and the included angle between the axis of the sleeve and the axis of the sludge discharge pipe is 1–5°, allowing the muddy water to be discharged more smoothly with the help of gravity, preventing sludge accumulation. This utility model has the characteristics of stable performance, simple structure, and good effect, which is conducive to its widespread promotion and use. Attached Figure Description

[0015] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0016] like Figure 1 As shown, this utility model provides a double-pipe sludge discharge structure, including a sludge discharge pipe 2 installed at the lower part of the sludge collection hopper 1 of the drainage equipment. The surface of the sludge discharge pipe 2 has a plurality of sludge discharge holes 21. The sludge discharge pipe 2 is provided with a sleeve 3 inside the sludge discharge pipe 2. The sleeve 3 is located in the lower part of the sludge discharge pipe 2 and has a plurality of water distribution holes 31.

[0017] The sludge discharge holes 21 are arranged in a linear array along the length of the sludge discharge pipe 2. In one specific embodiment, there are two rows of sludge discharge holes 21, which are symmetrically arranged on both sides below the sludge discharge pipe 2.

[0018] The water distribution holes 31 are arranged in a linear array along the length of the sleeve 3. In one specific embodiment, the water distribution holes 31 are arranged in a single row, directly below the sleeve 3.

[0019] In one specific embodiment, the ratio of the diameter of the sludge discharge hole 21 to the inner diameter of the sludge discharge pipe 2 is the same as the ratio of the diameter of the water distribution hole 31 to the inner diameter of the sleeve 3. Therefore, the diameter of the water distribution hole 31 is much smaller than the size of the sludge discharge hole 21, which can prevent large particles and debris in the sludge that have entered the sludge discharge pipe 2 from entering the sleeve 3 through the water distribution hole 31. This allows the sleeve 3 to mainly discharge sludge, and after most of the sludge is discharged, the debris accumulated in the sludge discharge pipe 2 can also be flushed out smoothly, preventing siltation.

[0020] The number of sleeves 3 is set according to the ratio of the inner diameter of the sludge discharge pipe 2 to the inner diameter of the sleeve 3. In one specific embodiment, when the inner diameter of the sludge discharge pipe 2 is greater than 5 times the inner diameter of the sleeve 3, a second sleeve 3 is arranged on one side of the sleeve 3.

[0021] In one specific embodiment, the bottom surface of the sludge discharge hopper is arranged horizontally, while the sludge discharge pipe 2 is arranged inclined downwards towards its outlet, and the sleeve 3 is also arranged inclined downwards towards its outlet. The slope angle between the axis of the sludge discharge pipe 2 and the bottom surface of the sludge collection hopper 1 is 1–5°, and the included angle between the axis of the sleeve 3 and the axis of the sludge discharge pipe 2 is 1–5°. The slope angle and included angle can be adjusted according to actual usage conditions. For example, if the local mud is thick, the slope angle value can be increased, and vice versa, so that the mud can be discharged more smoothly with the help of gravity.
