[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be arbitrarily combined with each other.
[0029] The present application provides a circulating water pool device, comprising a pool body and at least one separation structure for separating impurities in sewage, the pool body comprising a bottom wall, a first side wall, a second side wall, a third side wall and a fourth side wall, the separation structure comprising a first water blocking wall and a second water blocking wall spaced apart on a side of the first water blocking wall away from the first side wall, both side walls of the first water blocking wall are fixedly connected to the second side wall and the fourth side wall respectively, the top surface of the first water blocking wall is higher than the top surface of the pool body or flush with the top surface of the pool body, a first channel is formed between the bottom surface of the first water blocking wall and the bottom wall; the space between the second water blocking wall and the first water blocking wall constitutes a second channel, both side walls of the second water blocking wall are fixedly connected to the second side wall and the fourth side wall respectively, the bottom surface of the second water blocking wall is fixedly connected to the bottom wall, and the top surface of the second water blocking wall is lower than the top surface of the first water blocking wall and the top surface of the pool body. When sewage enters the circulating water pool device, impurities with density less than water become floating objects floating on the liquid surface, and impurities with density greater than water settle on the bottom wall to become sediment. As the circulating water pool device continues to inflow water, sewage flows from the first channel to the second channel. Due to the action of gravity and the impact of water flow, sediment will accumulate in the first channel and close to the second water blocking wall. In this way, floating objects and sediments in sewage can be effectively separated to achieve the reuse of water resources.
[0030] Some specific implementation modes described below are intended to facilitate those skilled in the art to understand the present embodiment, and the present embodiment is not limited to some specific implementation modes described below.
[0031] like Figure 1-Figure 3As shown, an exemplary embodiment of the present application provides a circulating water pool device, including a pool body 1 and at least one separation structure 2 for separating impurities in sewage. The pool body 1 includes a bottom wall 11 and a first side wall 12, a second side wall 13, a third side wall 14, and a fourth side wall 15 connected to the bottom wall 11 in sequence. The separation structure 2 includes a first water blocking wall 21 and a second water blocking wall 22 spaced apart and arranged on the side of the first water blocking wall 21 away from the first side wall 12, and the two side walls of the first water blocking wall 21 are fixedly connected to the second side wall 13 and the fourth side wall 15 respectively, and the top surface of the first water blocking wall 21 is higher than the top surface of the pool body 1 or flush with the top surface of the pool body 1, and a first channel 23 is formed between the bottom surface of the first water blocking wall 21 and the bottom wall 11. The space between the second water blocking wall 22 and the first water blocking wall 21 constitutes a second channel 24. The two side walls of the second water blocking wall 22 are fixedly connected to the second side wall 13 and the fourth side wall 15 respectively. The bottom surface of the second water blocking wall 22 is fixedly connected to the bottom wall 11. The top surface of the second water blocking wall 22 is lower than the top surface of the first water blocking wall 21 and the top surface of the tank body 1. When sewage flows from the first channel 23 to the second channel 24, impurities in the sewage are precipitated. The connection between the first water blocking wall 21, the second water blocking wall 22 and the tank body 1 can be made into a whole by pouring concrete.
[0032] In this embodiment, the top surface of the first water blocking wall 21 is higher than the top surface of the pool body 1 or flush with the top surface of the pool body 1, which can prevent sewage from overflowing; the top surface of the second water blocking wall 22 is lower than the top surface of the first water blocking wall 21 and the top surface of the pool body 1, so that the water flow path line 30 is "S"-shaped. When sewage enters the circulating water pool device, impurities with a density less than that of water become floating objects 10 floating on the liquid surface, and impurities with a density greater than that of water are precipitated on the bottom wall 11 to become sediment 20. As the circulating water pool device continues to inflow water, when sewage flows from the first channel 23 to the second channel 24, due to the action of gravity and the impact of water flow, the sediment 20 will accumulate in the first channel 23 and close to the second water blocking wall 22. In this way, the floating objects 10 and the sediment 20 in the sewage can be effectively separated, and the reuse of water resources can be realized.
[0033] In one embodiment, the first side wall 12, the second side wall 13, the first water blocking wall 21 close to the first side wall 12, the fourth side wall 15 and the bottom wall 11 enclose a sewage collection tank 3, and at least one sewage return pipe 31 is arranged on the sewage collection tank 3, and the outlet of the sewage return pipe 31 is lower than the top surface of the sewage collection tank 3.
[0034] In this embodiment, sewage enters the sewage collection tank 3 through the sewage return pipe 31 for collecting sewage. The outlet of the sewage return pipe 31 is lower than the top surface of the sewage collection tank 3, so that sewage can flow into the sewage collection tank 3 more easily through the sewage return pipe 31 and is not easy to splash outside the tank, thereby keeping the outside of the circulating water tank clean.
[0035] In one embodiment, the second side wall 13 and / or the fourth side wall 15 is provided with a sewage outlet 151 near the bottom wall 11 . The sewage outlet 151 is provided in the first channel 23 and near the second water blocking wall 22 .
[0036] When the filtered sediment 20 and floating objects 10 in the circulating water pool accumulate to a certain extent, they need to be cleaned regularly to prevent the accumulation of too much sediment 20 and blockage of the first channel 23. In addition, since the impurities of the sediment 20 are mainly accumulated in the first channel 23 and close to the second water blocking wall 22, the sewage outlet 151 is set here in this embodiment, which can make sewage discharge easier.
[0037] In another embodiment, the second side wall 13 and / or the fourth side wall 15 is provided with a sewage outlet 151 near the bottom wall 11 , and the sewage outlet 151 is provided near the third side wall 14 .
[0038] In this embodiment, the sewage outlet 151 can also be set near the third side wall 14. The amount of impurities at the third side wall 14 is relatively small, and the water quality can be judged by the sewage discharge there, so as to clean the circulating water pool device in time.
[0039] In one embodiment, the circulating water pool device also includes a sewage discharge component 4, which includes a sewage pipe 41 and a sewage valve 42. One end of the sewage pipe 41 is inserted into the sewage outlet 151, and the other end of the sewage pipe 41 is arranged outside the pool body 1. The sewage valve 42 is located on the sewage pipe 41 outside the pool body 1.
[0040] The sewage discharge assembly 4 corresponds to the sewage discharge port 151 one by one. For example, Figure 2 There are three sewage outlets 151, and the three sewage outlets 151 are all arranged on the fourth side wall 15. Accordingly, Figure 1 There are also three sewage discharge components 4. One end of the sewage discharge pipe 41 is inserted into the sewage discharge port 151 and is flush with the inner wall of the tank body 1, and the other end of the sewage discharge pipe 41 is arranged outside the tank body 1 and connected to a drainage ditch (not shown in the figure) arranged outside the tank body 1; in this embodiment, the discharge of the sediment 20 can be better controlled by the sewage discharge valve 42.
[0041] In one embodiment, the second water blocking wall 22 near the third side wall 14, the second side wall 13, the third side wall 14, the fourth side wall 15 and the bottom wall 11 enclose a clean water reservoir 5, and an overflow pipe 51 is provided at a location of the clean water reservoir 5 away from the bottom wall 11. The outlet end of the overflow pipe 51 may be connected to a drainage ditch.
[0042] In this embodiment, impurities in the sewage are separated and enter the clean water reservoir 5 to become clean water that can be reused. An overflow pipe 51 is provided in the clean water reservoir 5, so that excess water in the cleaning reservoir can be discharged into the drain ditch through the overflow pipe 51 to avoid the total amount of water entering the tank body 1 being greater than the total amount of water discharged from the tank body 1, causing sewage to overflow from the upper edge of the tank body 1 and causing sanitary pollution.
[0043] In one embodiment, a liquid level control component 52 is provided on the clean water reservoir 5, and the liquid level control component 52 includes a float valve 521 located at the liquid level of the clean water reservoir 5 and a water supply pipe 522 connected to the float valve 521, and the end of the water supply pipe 522 away from the float valve 521 is connected to a water supply main (not shown in the figure); the clean water reservoir 5 is set with a minimum liquid level, and when the liquid level of the clean water reservoir 5 is at the minimum liquid level, the liquid level control component 52 replenishes water to the clean water reservoir 5.
[0044] In this embodiment, the clean water reservoir 5 is provided with a minimum liquid level. The liquid level control component 52 can ensure that the liquid level in the clean water reservoir 5 is automatically maintained within the preset value range, thereby ensuring that the water supply to the production line is sufficient. When the float valve 521 detects that the liquid level is lower than the preset value of the minimum liquid level, it will automatically open the water supply pipe 522 switch to replenish the clean water reservoir 5, and automatically stop replenishing water after the water level is replenished to within the normal range of the preset value.
[0045] In one embodiment, a water supply assembly 53 is provided on the side wall of the clean water reservoir 5, and the water supply assembly 53 includes a water supply pipe 531 and a water pump 532 connected to the water supply pipe 531, one end of the water supply pipe 531 is connected to the clean water reservoir 5, and the other end of the water supply pipe 531 is connected to the water end of the production line, and the water inlet end of the water supply pipe 531 is lower than the lowest liquid level of the clean water reservoir 5.
[0046] In this embodiment, through the setting of the water supply component 53, the clean water that enters the clean water reservoir 5 after filtering and sedimentation can be used for production line water, forming a complete water cycle; the setting of the water pump 532 can ensure the stability of the water pressure of the water supply pipe 531, and the water inlet end of the water supply pipe 531 is lower than the lowest liquid level of the clean water reservoir 5, so that continuous water supply can be maintained.
[0047] In one embodiment, a plurality of separation structures 2 are provided, and the plurality of separation structures 2, the second side wall 13, the fourth side wall 15 and the bottom wall 11 enclose a self-sedimentation tank 6. The number of separation structures 2 is not limited and can be determined according to the impurities in the sewage. For example, Figure 2 There are two separation structures 2 in the embodiment.
[0048] Exemplarily, the circulating water pool device includes a pool body 1 and two separation structures 2. The pool body 1 includes a bottom wall 11 and a first side wall 12, a second side wall 13, a third side wall 14 and a fourth side wall 15 connected to the bottom wall 11 in sequence. The pool body 1 is in a rectangular parallelepiped shape. The two separation structures 2 are spaced apart along the length direction of the pool body 1 (i.e., the length direction of the second side wall 13 and the fourth side wall 15). The first side wall 12, the second side wall 13, the first water blocking wall 21 near the first side wall 12, the fourth side wall 15 and the bottom wall 11 enclose a sewage collection pool 3; the first water blocking wall 21 near the first side wall 12, the second side wall 13, the second water blocking wall 22 near the third side wall 14, the fourth side wall 15 and the bottom wall 11 enclose a self-sedimentation pool 6; the second water blocking wall 22 near the third side wall 14, the second side wall 13, the third side wall 14, the fourth side wall 15 and the bottom wall 11 enclose a clean water reservoir 5.
[0049] In one embodiment, the tank body 1 is a concrete tank body 1 .
[0050] In this embodiment, the provision of the concrete structure can make the pool body 1 more solid and effectively extend its service life.
[0051] In one embodiment, the inner wall of the pool body 1 is provided with a waterproof layer and a ceramic layer in sequence.
[0052] In this embodiment, a waterproof layer is provided on the inner wall of the pool body 1, which can reduce the risk of leakage during use, and the provision of the ceramic layer can reduce the surface roughness of the pool body 1, thereby reducing the probability of impurities in sewage adhering to the inner wall of the pool and facilitating regular cleaning of the pool.
[0053] An exemplary embodiment of the present application provides a working principle of a circulating water pool device:
[0054] The pool body 1 of the circulating water pool device is divided by two separation structures 2 to form a sewage collection pool 3, a self-sedimentation pool 6, and a clean water storage pool 5. Sewage enters the sewage collection pool 3 through the sewage return pipe 31, and impurities with a density less than that of water become floating objects 10 floating on the liquid surface, and impurities with a density greater than that of water settle on the bottom wall 11 to become sediments 20. As the sewage collection pool 3 continues to be filled with water, the sewage flows from the first channel 23 of the first separation structure 2 to the second channel 24, and then enters the self-sedimentation pool 6. At this time, most of the floating objects 10 in the sewage are isolated in the sewage collection pool 3, and most of the sediments 20 accumulate in the first channel 23 near the second water blocking wall 22; when the sewage after one filtration and sedimentation flows from the first channel 23 of the second separation structure 2 to the second channel 24, the floating objects 10 and the sediments 20 in the sewage can be separated again, and then enter the clean water storage pool 5 to become clean water that can be reused. The clean water entering the clean water reservoir 5 is supplied to the production line through the water supply component 53, and the sewage generated by the production line water enters the sewage collection tank 3 through the sewage return pipe 31, thus forming a complete water cycle.
[0055] After the circulating water pool device has been used for a period of time, the impurities in the pool body 1 must be cleaned manually on a regular basis. First, close the water supply assembly 53 and the sewage return pipe 31, then open the three sets of sewage valves 42 to drain the water in the pool body 1, and the operator enters the sewage collection tank 3, the self-sedimentation tank 6 and the clean water storage tank 5 in turn to complete the cleaning operation. Then open the sewage return pipe 31, fill the pool body 1, and then open the water supply assembly 53 to start the next round of water circulation.
