Description

Technical Field

[0001] The utility model relates to the technical field of silt removal in a high-density coagulation sedimentation tank, in particular to a high-density coagulation sedimentation tank sedimentation removal device. Background Art

[0002] High-density sedimentation tank is an important part of the sewage treatment system. It is used to remove suspended matter in sewage by adding flocculants to achieve the purpose of purifying water quality.

[0003] In the normal water purification process, flocculants combine with particles to form coagulant flocs, which precipitate the sewage. The flocs overflow from the diversion tank to the water distribution tank, and then settle to the bottom of the water distribution tank under the action of gravity, and finally discharged in the form of sludge. A small amount of coagulant flocs will accumulate in the dead corner between the diversion tank and the baffle wall. Especially when the equipment needs to be repaired or shut down, the mud and sand in the water will be deposited in the dead corner together with the coagulant and block the area. When the equipment is started, the flocs that have been formed will be deflocculated again, and the particles in the water will be released again, which will directly affect the sedimentation effect of the water distribution tank after the equipment is turned on.

[0004] When the equipment is restarted after being shut down, the sediment deposited in the dead corner affects the sedimentation effect of the flocculant. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a high-density coagulation sedimentation tank desedimentation device, which uses compressed air to blow away the sediment deposited in the dead corner area through a main pipe, branch pipes, valves, and nozzle pipes.

[0006] In order to achieve the above object, the utility model is implemented through the following technical solutions:

[0007] A high-density coagulation sedimentation tank de-sedimentation device is used to remove the sediment deposited in the dead corner area between the diversion tank and the baffle wall by compressed air, comprising:

[0008] The main pipe is arranged outside the diversion pool and connected to the factory air pipeline for receiving compressed air.

[0009] The branch pipe is arranged on the outer wall of the main pipe and is located above the diversion pool, and its inlet end is fixedly connected to the main pipe.

[0010] The valve is installed on the branch pipe and is detachably connected to the branch pipe to cut off or connect the compressed air. The branch pipe is used to integrate the compressed air into the diversion pool.

[0011] The nozzle pipe is arranged at the outlet end of the branch pipe, connected to the branch pipe as a whole, located at the root of the baffle wall, opposite to the dead corner area, and is used to spray compressed air in three ways to blow away the mud and sand on the bottom of the diversion pool, the lower wall of the baffle, and the corner between the baffle wall and the diversion groove.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] The main pipe introduces compressed air into the branch pipe, and the compressed air is ejected from the nozzle pipe after passing through the branch pipe and valve. The nozzle pipe sprays compressed air to the upper, middle and lower areas of the dead corner area in three ways, completely flushing away the sediment deposited in the dead corner area, so that the sediment overflows from the diversion tank to the water distribution tank, and finally discharged from the high-density coagulation sedimentation tank in the form of sludge. Therefore, before starting the equipment, the pressure of compressed air can be used in three ways to completely blow away the sediment in different areas of the dead corner area and eliminate the situation where the sediment blocks the dead corner area. When the equipment is started, a new round of coagulation and sedimentation process begins to improve the sedimentation effect of the flocculant.

[0014] More preferably, the nozzle pipe comprises:

[0015] The diverter plate is inclined and arranged on the inner wall of the nozzle tube outlet. Its side wall is fixedly connected to the nozzle tube, and the bottom wall is fixedly connected to the bottom surface of the nozzle tube outlet. It is used to divide the compressed air in the nozzle tube into two paths, wherein the diverter plate and the inner wall of the nozzle tube form a bottom air outlet channel.

[0016] The baffle is arranged at the outlet of the nozzle pipe, is integrally connected with the bottom surface of the nozzle pipe, and forms an intermediate air outlet channel between the baffle and the inner wall of the nozzle pipe.

[0017] The spray hole is opened on the arc-shaped tube wall of the nozzle tube, located at the end of the nozzle tube, and forms a top air outlet channel with the diverter plate and the baffle plate.

[0018] By adopting the above technical scheme, the compressed air coming out of the bottom air outlet channel is directly aimed at the bottom surface of the diversion pool to blow away the silt deposited on the bottom surface of the diversion pool near the dead corner area; the compressed air ejected from the middle air outlet channel directly blows away the silt at the corner of the dead corner area, and the compressed air coming out of the top air outlet channel blows away the silt on the baffle wall near the dead corner area, and the silt blown from the middle air outlet channel and the bottom air outlet channel continues to blow to the top of the baffle wall until it overflows into the water distribution pool.

[0019] More preferably, the nozzle pipe is a continuous arc-shaped curved pipe.

[0020] The above technical solution makes the compressed air flow more smoothly in the nozzle pipe.

[0021] More preferably, one side of the top wall of the diverter plate is rounded.

[0022] By adopting the above technical solution, the compressed air is smoothly divided into two paths, the resistance of the compressed air is reduced, and the damage to the inner wall of the nozzle pipe is reduced.

[0023] A further optimization is that the side wall of the baffle plate facing the diverter plate is rounded.

[0024] By adopting the above technical solution, when the compressed air contacts the baffle, the rounded corners of the baffle can smoothly guide the compressed air to the middle air outlet channel, thereby reducing the damage to the edge of the baffle.

[0025] Further optimization is that the inner diameter of the mother pipe is DN65.

[0026] The above technical solution is adopted to meet the requirement of compressed air for flushing out sediment.

[0027] Further optimization is that the number of branch pipes is at least multiple, and the interval between every two adjacent branch pipes is 100 cm-80 cm.

[0028] By adopting the above technical solution, multiple branch pipes can simultaneously blow away the silt in the dead corner area, thereby achieving the purpose of clearing the silt.

[0029] Further optimization is that the multiple branch pipes are located on the same side of the main pipe and are arranged linearly.

[0030] By adopting the above technical solution, the sediment in the dead corner area can be blown away on the same side of the branch pipe.

[0031] Further optimization is that the valve is selected to be either a ball valve or a self-adjusting valve.

[0032] The above technical solution uses a ball valve with good sealing performance, which can completely cut off the compressed air to prevent air leakage during normal sedimentation. The self-adjusting valve can achieve remote control to cut off or connect the compressed air, achieving the purpose of automatically controlling the compressed air to blow away the sediment.

[0040] The following is combined with Figure 1-Figure 6 The utility model is further introduced in detail.

[0041] A high-density coagulation sedimentation tank de-sedimentation device is used to remove the sediment deposited in the dead corner area between the diversion tank 1 and the baffle wall 7 by compressed air, such as Figure 1 As shown, including:

[0042] The main pipe 3 is arranged outside the diversion pool 1 and connected to the factory air pipeline for receiving compressed air.

[0043] The branch pipe 4 is arranged on the outer wall of the main pipe 3 and is located above the diversion pool 1 , and its inlet end is fixedly connected to the main pipe 3 .

[0044] The valve 5 is installed on the branch pipe 4 and is detachably connected to the branch pipe 4 for cutting off or connecting compressed air. The branch pipe 4 is used to introduce the compressed air into the diversion pool 1 .

[0045] The nozzle pipe 6 is arranged at the outlet end of the branch pipe 4. Figure 1 and Figure 2 As shown, it is integrally connected with the branch pipe 4, located at the root of the baffle wall 7, opposite to the dead corner area, and is used to spray compressed air in three ways to blow away the mud and sand on the bottom surface of the diversion pool 1, the lower wall of the baffle, and the corner between the baffle wall 7 and the diversion groove.

[0046] The main pipe 3 introduces compressed air into the branch pipe 4. The compressed air passes through the branch pipe 4 and the valve 5 and then is ejected from the nozzle pipe 6. The nozzle pipe 6 sprays the compressed air to the upper, middle and lower areas of the dead corner area in three ways, which completely flushes away the sediment deposited in the dead corner area, allowing the sediment to overflow from the diversion tank 1 to the water distribution tank 2, and finally be discharged from the high-density coagulation sedimentation tank in the form of sludge. Therefore, before starting the equipment, the pressure of compressed air can be divided into three ways to completely blow away the sediment in different areas of the dead corner area and eliminate the situation where the sediment blocks the dead corner area. When the equipment is started, a new round of coagulation and sedimentation process begins to improve the sedimentation effect of the flocculant.

[0047] Specifically, Figure 3 , Figure 4 as well as Figure 5 As shown, the nozzle pipe 6 in this embodiment includes:

[0048] The diverter plate 61 is inclined and arranged on the inner wall of the nozzle tube 6 outlet. Its side wall is fixedly connected to the nozzle tube 6, and the bottom wall is fixedly connected to the bottom surface of the nozzle tube 6 outlet. It is used to divide the compressed air in the nozzle tube 6 into two paths, wherein the diverter plate 61 and the inner wall of the nozzle tube 6 form a bottom air outlet channel.

[0049] The baffle 62 is arranged at the outlet of the nozzle tube 6 , is integrally connected to the bottom surface of the nozzle tube 6 , and forms an intermediate air outlet channel with the diverter plate 61 and the inner wall of the nozzle tube 6 .

[0050] The spray hole 63 is formed on the arc-shaped tube wall of the spray head tube 6 and is located at the end of the spray head tube 6 , and forms a top air outlet channel together with the diverter plate 61 and the baffle plate 62 .

[0051] The compressed air coming out of the bottom air outlet channel is directly aimed at the bottom surface of the diversion pool 1 to blow away the silt deposited on the bottom surface of the diversion pool 1 near the dead corner area; the compressed air ejected from the middle air outlet channel directly blows away the silt at the corner of the dead corner area, and the compressed air coming out of the top air outlet channel blows away the silt on the baffle wall 7 near the dead corner area, and the silt blown from the middle air outlet channel and the bottom air outlet channel continues to blow to the top of the baffle wall 7 until it overflows to the water distribution pool 2.

[0052] Specifically, Figure 1 and Figure 2 As shown, in this embodiment, the nozzle pipe 6 is a continuous arc-shaped curved pipe, so that the compressed air can flow more smoothly in the nozzle pipe 6.

[0053] Specifically, Figure 5 and Figure 6 As shown, in this embodiment, one side of the top wall of the diverter plate 61 is rounded to smoothly divide the compressed air into two paths, thereby reducing the resistance of the compressed air and reducing damage to the inner wall of the nozzle tube 6.

[0054] Specifically, Figure 5 and Figure 6 As shown, in this embodiment, the side wall of the baffle 62 facing the diverter plate 61 is rounded. When the compressed air contacts the baffle 62, it can be smoothly guided to the middle air outlet channel by the rounded part of the baffle 62, reducing the damage of the compressed air to its edge.

[0055] Specifically, Figure 5 and Figure 6 As shown, in this embodiment, the inner diameter of the mother pipe 3 is DN65, which meets the requirement of compressed air for flushing out sediment.

[0056] Specifically, Figure 1 , Figure 2 as well as Figure 3As shown, in this embodiment, the number of branch pipes 4 is at least multiple, and the interval between each two adjacent branch pipes 4 is 100cm-80cm. Multiple branch pipes 4 can simultaneously blow away the silt in the dead corner area, and the silt in this range is almost blown away at one time, achieving the purpose of cleaning the silt. When the interval between two adjacent branch pipes 4 is 100cm, it is suitable for high-density coagulation sedimentation tanks with a long length, which can not only save the material cost of the branch pipes 4 and the nozzle pipe 6, but also achieve the effect of efficiently cleaning the silt. When the interval between two adjacent branch pipes 4 is 80cm, it is suitable for high-density coagulation sedimentation tanks with a short length, which can clean the silt more reasonably.

[0057] Specifically, Figure 1 , Figure 2 as well as Figure 3 As shown, in this embodiment, a plurality of branch pipes 4 are located on the same side of the main pipe 3 and are arranged linearly, so as to achieve the effect of blowing away the sediment in the dead corner area on the same side of the branch pipes 4 .

[0058] Specifically, as shown in the figure Figure 2 As shown, in this embodiment, the valve 5 is selected from either a ball valve or a self-adjusting valve. The ball valve has good sealing performance and can completely cut off the compressed air to prevent air leakage during normal sedimentation. The self-adjusting valve can realize remote control to cut off or connect the compressed air, so as to achieve the purpose of automatically controlling the compressed air to blow away the sediment.

[0059] Please refer to Figure 1-Figure 6 The process of flushing out sediment in this embodiment is described as follows:

[0060] Before starting the equipment, it is necessary to clean the silt in the dead corners, specifically by connecting the main pipe 3 to the compressed air pipeline in the plant area, connecting the compressed air to the branch pipe 4, and opening the valve 5 to deliver the compressed air to the nozzle pipe 6. The compressed air is sprayed out from the bottom outlet channel, the middle outlet channel, and the top outlet channel in three ways, respectively, to flush out the silt in the dead corner area near the bottom of the diversion pool 1, the corner of the dead corner area, and the dead corner area near the baffle wall 7. At the same time, the silt blown from the bottom outlet channel and the fixed outlet channel is connected to the top of the baffle wall 7 vertically, so that the silt overflows to the water distribution pool 2, and then is discharged from the water distribution pool 2, so that the silt can be thoroughly cleaned and the sedimentation effect is improved.

[0061] This specific embodiment is merely an explanation of the utility model, and it is not a limitation of the utility model. After reading this specification, those skilled in the art can make non-creative modifications to the embodiment as needed, but as long as it is within the protection scope of the utility model, it is protected by the patent law.
