Abstract
Description
Technical Field
[0001] This utility model belongs to the field of hydraulic perforation and mud removal technology, specifically relating to a hydraulic perforation and mud removal square tube. Background Technology
[0002] In conventional wastewater treatment, perforated sludge discharge typically uses circular perforated sludge discharge pipes, which are fixed to the bottom of the tank through secondary casting. After prolonged use, the perforations gradually become clogged, requiring periodic emptying of the sedimentation tank for cleaning, which is inconvenient and costly.
[0003] For example, if sludge is not discharged for a long time, it will settle in the sludge discharge pipe and cause blockage. Since the sludge discharge pipe is a circular closed type, the sludge is difficult to clean and can only be replaced by perforating the sludge discharge pipe. Utility Model Content
[0004] (1) Technical problems to be solved
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hydraulic perforated mud discharge square pipe. This hydraulic perforated mud discharge square pipe aims to solve the technical problem that the mud discharge pipe is blocked by sediment, and because the mud discharge pipe is circular and closed, the mud is difficult to clean and can only be replaced by perforating the mud discharge pipe.
[0006] (2) Technical solution
[0007] To solve the above-mentioned technical problems, this utility model provides a hydraulic perforated sludge discharge square pipe, which includes a casting pool bottom and a hydraulic sludge discharge pipe embedded in the top of the casting pool bottom. The top of the hydraulic sludge discharge pipe has a cleaning cavity, and both sides of the top surface of the hydraulic sludge discharge pipe are equipped with sludge discharge cover plates that seal the cleaning cavity through a rotating connection mechanism. A sludge discharge connecting pipe is installed on the side wall of the hydraulic sludge discharge pipe, a sludge discharge sleeve valve is installed at the top of the sludge discharge connecting pipe, and a backwash connecting pipe is fixed at the bottom of the sludge discharge connecting pipe.
[0008] When using this technical solution, a backwash pipe is installed at the bottom of the sludge discharge connecting pipe. After flushing water is introduced into the backwash pipe, the sludge discharge connecting pipe and the inside of the hydraulic sludge discharge pipe are flushed. During the flushing process, the sludge in the sludge discharge hole is flushed out. The hydraulic sludge discharge pipe can be maintained and cleaned without emptying the sedimentation tank, which reduces the cleaning cost of the hydraulic sludge discharge pipe. By rotating and installing sludge discharge cover plates on both sides of the top surface of the hydraulic sludge discharge pipe, when sludge settles in the hydraulic sludge discharge pipe, after emptying the sedimentation tank, the sludge discharge cover plate is pulled along the pin between the first connecting plate and the second connecting plate through the sludge discharge hole, thereby opening the top of the hydraulic sludge discharge pipe and flushing the sludge accumulated inside the hydraulic sludge discharge pipe, which improves the convenience of sludge cleaning.
[0009] Preferably, a control valve is fixedly installed at the top end of the backwash connection pipe, and a connection part is installed on the backwash connection pipe.
[0010] Furthermore, a sludge discharge trough is provided at the bottom of the end of the hydraulic sludge discharge pipe away from the sludge discharge connecting pipe, and a sludge discharge channel connected to the sludge discharge trough is provided at the bottom of the casting pool.
[0011] Furthermore, the top of the inner wall of the hydraulic sludge discharge pipe is fixed with support plates at equal intervals, and the tops of the multiple support plates respectively contact and support the two sludge discharge cover plates.
[0012] Furthermore, the outer walls of the hydraulic sludge discharge pipe are provided with grooves at equal intervals on both sides, and the rotating connection mechanism includes a first connecting plate and a second connecting plate.
[0013] Furthermore, a pin is installed between the first connecting plate and the second connecting plate, and the second connecting plate is embedded and fixed in the groove.
[0014] Furthermore, the sidewalls of the first connecting plate and the second connecting plate are respectively provided with a first bolt and a second bolt. The first bolt and the second bolt are respectively threaded into the inner wall of the sludge discharge cover and the groove. The top of the sludge discharge cover is provided with sludge discharge holes at equal intervals.
[0015] (3) Beneficial effects
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This utility model has a backwash pipe installed at the bottom of the sludge discharge connecting pipe. After the backwash pipe is filled with flushing water, it flushes the inside of the sludge discharge connecting pipe and the hydraulic sludge discharge pipe. During the flushing process, the sludge in the sludge discharge hole is flushed out. The hydraulic sludge discharge pipe can be maintained and cleaned without emptying the sedimentation tank, which reduces the cleaning cost of the hydraulic sludge discharge pipe.
[0018] By rotating and installing sludge discharge covers on both sides of the top surface of the hydraulic sludge discharge pipe, when sludge settles in the hydraulic sludge discharge pipe, after emptying the sedimentation tank, the sludge discharge covers are pulled along the pin between the first connecting plate and the second connecting plate through the sludge discharge hole, thereby opening the top of the hydraulic sludge discharge pipe and flushing the sludge accumulated inside the hydraulic sludge discharge pipe, thus improving the convenience of cleaning sludge.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This specific embodiment is a hydraulically perforated mud-discharging square pipe, the structural diagram of which is shown below. Figure 1 and Figure 2 As shown, the hydraulic perforated sludge discharge square pipe includes a casting pool bottom 2 and a hydraulic sludge discharge pipe 1 embedded in the top of the casting pool bottom 2. The top of the hydraulic sludge discharge pipe 1 has a cleaning chamber, and both sides of the top surface of the hydraulic sludge discharge pipe 1 are equipped with sludge discharge cover plates 10 that seal the cleaning chamber through a rotating connection mechanism. The side wall of the hydraulic sludge discharge pipe 1 is equipped with a sludge discharge connecting pipe 7, the top of the sludge discharge connecting pipe 7 is equipped with a sludge discharge sleeve valve 6, and the bottom end of the sludge discharge connecting pipe 7 is fixed with a backwash connecting pipe 3. The top of the casting pool bottom 2 has a reserved groove 15. After the bottom end of the hydraulic sludge discharge pipe 1 is embedded in the groove 15, cement is poured a second time into the casting pool bottom 2 to maintain a sealed connection between the hydraulic sludge discharge pipe 1 and the casting pool bottom 2. The bottom surface of the second-poured pool is slightly higher than the top of the hydraulic sludge discharge pipe 1 so that the sludge can flow into the sludge discharge hole 12.
[0027] A control valve 4 is fixedly installed at the top of the backwash connection pipe 3, and a connection part 5 is installed on the backwash connection pipe 3. The connection part 5 is connected to a pipe with pressurized water, including a tap water pipe or a water pump pipe. A sludge discharge trough 9 is opened at the bottom of the end of the hydraulic sludge discharge pipe 1 away from the sludge discharge connection pipe 7. A sludge discharge channel 8 connected to the sludge discharge trough 9 is opened at the bottom of the casting pool 2. Support plates 11 are fixed at equal intervals at the top of the inner wall of the hydraulic sludge discharge pipe 1. The tops of multiple support plates 11 are respectively in contact with two sludge discharge cover plates 10 for support. After the backwash pipe is fed with flushing water, it flushes the sludge discharge connection pipe 7 and the inside of the hydraulic sludge discharge pipe 1. During the flushing process, the sludge in the sludge discharge hole 12 is flushed out. The hydraulic sludge discharge pipe 1 can be maintained and cleaned without emptying the sedimentation tank, which reduces the cleaning cost of the hydraulic sludge discharge pipe 1.
[0028] like Figure 3 and Figure 4 As shown, grooves 15 are equally spaced on both sides of the outer wall of the hydraulic sludge discharge pipe 1. The rotating connection mechanism includes a first connecting plate 13 and a second connecting plate 16. A pin is installed between the first connecting plate 13 and the second connecting plate 16. The second connecting plate 16 is embedded and fixed in the groove 15. A first bolt 14 and a second bolt 17 are respectively provided on the side walls of the first connecting plate 13 and the second connecting plate 16. The first bolt 14 and the second bolt 17 are respectively threaded into the sludge discharge cover plate 10 and the inner wall of the groove 15. Sludge discharge holes 12 are equally spaced at the top of the sludge discharge cover plate 10. When sludge settles in the hydraulic sludge discharge pipe 1, after the sedimentation tank is emptied, the sludge discharge cover plate 10 is pulled along the pin between the first connecting plate 13 and the second connecting plate 16 through the sludge discharge holes 12, thereby opening the top of the hydraulic sludge discharge pipe 1 and flushing the sludge accumulated inside the hydraulic sludge discharge pipe 1.
[0029] Working principle: When using the device of this technical solution, the sludge in the sedimentation tank is discharged from the sludge discharge trough 9 and sludge discharge channel 8 through the sludge discharge hole 12 at the top of the hydraulic sludge discharge pipe 1. The hydraulic perforated sludge discharge square pipe is perforated on the sludge discharge cover plate 10. At the same time, the hydraulic sludge discharge pipe 1 is used in conjunction with the sludge discharge sleeve valve 6. The sludge in the sludge discharge connecting pipe 7 flows into the hydraulic sludge discharge pipe 1, and pressure is applied to the sludge inside the hydraulic sludge discharge pipe 1 to achieve effective and smooth sludge discharge. After the backwash pipe is introduced with flushing water, it cleans the sludge discharge connecting pipe 7 and the inside of the hydraulic sludge discharge pipe 1. The system is flushed, and the sludge in the sludge discharge hole 12 is flushed out during the flushing process. The hydraulic sludge discharge pipe 1 can be maintained and cleaned without emptying the sedimentation tank, which reduces the cleaning cost of the hydraulic sludge discharge pipe 1. When sludge settles in the hydraulic sludge discharge pipe 1, after emptying the sedimentation tank, the sludge discharge cover plate 10 is pulled along the pin between the first connecting plate 13 and the second connecting plate 16 through the sludge discharge hole 12, thereby opening the top of the hydraulic sludge discharge pipe 1 and flushing the sludge accumulated inside the hydraulic sludge discharge pipe 1, which improves the convenience of cleaning sludge.
[0030] All technical features in this embodiment can be freely combined according to actual needs.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
