Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment equipment, in particular to a reverse osmosis concentrated water tank for sludge treatment. Background Technique

[0002] During the sludge treatment process, a large amount of wastewater will be generated. In order to make these wastewaters meet the environmental protection standards before discharge, reverse osmosis technology will be used to deeply treat the wastewaters. During the reverse osmosis treatment process, a part of concentrated liquid, namely concentrated water, will be generated. This part of concentrated water contains a relatively high solute concentration, and direct discharge may cause environmental pollution. Therefore, it is necessary to set up a concentrated water tank to collect and manage this part of concentrated water for subsequent further treatment or safe disposal.

[0003] When treating the wastewater generated during the sludge treatment process, first use a water pump to transport the sewage into the osmosis tank, and use the purification and filtration of the reverse osmosis membrane to treat the wastewater. Then, the concentrated water generated during the treatment process is transported into the interior of the concentrated water tank through a delivery pipe for storage. During the process of using the water pump to transport the sewage into the osmosis tank, due to the pressure existing during the sewage transportation process and the excessive aggregation of the sewage when it enters the osmosis tank, the sewage exerts a relatively large impact force on the reverse osmosis membrane. When the sewage collides with the reverse osmosis membrane, due to the sudden change in the water flow velocity, the pressure fluctuates, which in turn causes a strong mechanical impact on the reverse osmosis membrane element. Under the long-term impact, the structure of the membrane element will be damaged, such as the membrane sheet cracking and the bonding line breaking, thereby shortening the service life of the reverse osmosis membrane. Moreover, the excessive aggregation of the sewage will result in too low contact area between the sewage and the reverse osmosis membrane, thus causing low utilization rate of the reverse osmosis membrane and a decline in the treatment quality of the sewage.

[0004] Therefore, there is an urgent need for a reverse osmosis concentrated water tank for sludge treatment to solve the above problems. Content of the Utility Model

[0025] It should be noted here that: through the setting of the impact reduction component, under the cooperative action of the control component, the wastewater flows towards the surface of the reverse osmosis membrane 105 from multiple directions intermittently, thereby reducing the impact force on the reverse osmosis membrane 105, ensuring the service life of the reverse osmosis membrane 105, while increasing the contact area between the wastewater and the reverse osmosis membrane 105, thus improving the utilization rate of the reverse osmosis membrane 105 and the quality of sewage treatment.

[0026] It should be noted that: the working principle and specific structure of the reverse osmosis concentrated water tank for wastewater treatment have been mastered by those skilled in the art, and will not be elaborated here.

[0027] Please refer to Figure 4 , on the side of the mounting ring 201 close to the reverse osmosis membrane 105 in the figure, a plurality of through holes 204 are provided;

[0028] It should be noted here that: through the setting of the plurality of through holes 204 on the bottom wall of the mounting ring 201, it is used for the wastewater to flow towards the surface of the reverse osmosis membrane 105 from multiple directions, thereby increasing the contact area with the reverse osmosis membrane 105.

[0029] Please refer to Figure 4 and Figure 5 , in the figure, the control component includes a rotating rod 301 rotatably connected to the side of the mounting ring 201 close to the reverse osmosis membrane 105. At one end of the rotating rod 301 located inside the mounting ring 201, a plurality of control plates 302 are fixedly connected. A plurality of T-shaped control rods 303 are slidably connected to each control plate 302, and each control plate 302 is provided with a telescopic component for telescoping the T-shaped control rod 303;

[0030] It should be noted here that: through the setting of the control component, it is used for intermittently blocking each through hole 204, so as to realize the wastewater flowing towards the surface of the reverse osmosis membrane 105 from multiple directions intermittently, thereby reducing the impact force on the reverse osmosis membrane 105.

[0031] Please refer to Figure 4 and Figure 5 , on the side of each T-shaped control rod 303 close to the through hole 204 in the figure, a tapered rod 304 is fixedly connected;

[0032] It should be noted here that: through the setting of the tapered rod 304, by using the tapered surface of the tapered rod 304, it can not only block the through hole 204, but also provide a driving force for the rotation of the T-shaped control rod 303.

[0033] Please refer to Figure 5 , in the figure, the telescopic component includes a fixed ring 401 fixedly connected to the side wall of the T-shaped control rod 303. A spring 402 is sleeved on the side wall of the T-shaped control rod 303, and both ends of the spring 402 are connected to the control plate 302 and the fixed ring 401 respectively;

[0034] It should be noted here that: through the setting of the telescopic component, when the conical rod 304 is aligned with the through hole 204, under the elastic action of the telescopic component, the conical rod 304 will be pushed to align with the through hole 204, so as to provide a reset function for the T-shaped control rod 303.

[0035] Working principle: During the sludge treatment process, a large amount of wastewater will be generated. In order to make this wastewater meet the environmental protection standards before discharge, reverse osmosis technology is used to deeply treat the wastewater. During the reverse osmosis treatment process, a part of the concentrated liquid, that is, the concentrated water, will be generated. This part of the concentrated water has a high solute concentration and direct discharge may cause environmental pollution. Therefore, a concentrated water tank needs to be set up to collect and manage this part of the concentrated water for further treatment or safe disposal later;

[0036] When treating the wastewater generated during sludge treatment, first, the wastewater flows from the water inlet pipe 104 into the permeation tank body 102. When the wastewater flows from the water inlet pipe 104 into the permeation tank body 102, the wastewater will impact on the impact reduction plate 202. Then, under the buffering action of the impact reduction plate 202 on the wastewater, the wastewater will disperse and flow towards the side wall of the mounting ring 201 through each impact reduction hole 203 and flow along the inner wall of the mounting ring 201 to the bottom wall of the mounting ring 201;

[0037] After the dispersed wastewater flows to the bottom wall of the mounting ring 201, under the action of the driving member, the plurality of control plates 302 on the side wall of the rotating rod 301 are driven to rotate. During the rotation of each control plate 302, each T-shaped control rod 303 will be driven to rotate. During the rotation of each T-shaped control rod 303, when the conical rod 304 at one end of the T-shaped control rod 303 abuts against the side wall of the through hole 204, under the mutual acting force, the conical rod 304 will be pushed to move closer to the control plate 302, thus releasing the blockage of the through hole 204. When the conical rod 304 is aligned with the through hole 204, under the elastic action of the telescopic component, the conical rod 304 will be pushed to align with the through hole 204, thereby blocking the through hole 204. Thus, under the rotation action of the control plate 302, the conical rod 304 will reciprocally block and release the blockage of the through hole 204, so that the wastewater flowing to the bottom wall of the mounting ring 201 flows to the surface of the reverse osmosis membrane 105 from multiple directions and intermittently. Thus, while reducing the impact force on the reverse osmosis membrane 105 and ensuring the service life of the reverse osmosis membrane 105, the contact area between the wastewater and the reverse osmosis membrane 105 is increased, thereby improving the utilization rate of the reverse osmosis membrane 105 and the quality of sewage treatment.

[0038] Embodiment 2

[0039] Please refer to Figure 4, this embodiment further elaborates on Example 1. In the illustrated installation ring 201, there is a driving member for driving each control board 302. The driving member is a driving motor 5, which is arranged on the side of the installation ring 201 close to the reverse osmosis membrane 105. The output end of the driving motor 5 is connected to the rotating rod 301;

[0040] It should be noted here that: through the setting of the driving member, under the action of the driving motor 5, each control board 302 will be driven to rotate.
