Technical Field

[0002] Commercial concrete stations produce a large amount of slurry during the production process. If these slurries are discharged directly, it will not only cause environmental pollution, but also waste precious water resources. By recycling and treating these slurries, environmental pollution can be reduced, pollution problems can be effectively solved, and the environment can be protected. It can also greatly reduce the use of fresh water and save water resources. At the same time, recycling and reusing the useful components in the wastewater can improve resource utilization efficiency.

[0003] In the prior art, the recovery device for commercial concrete station slurry water needs to use disinfectants to disinfect the slurry water. In the commonly used scheme, the commercial concrete station slurry water is directly injected into the inside of the disinfection tank, and then the disinfectant is sprayed and left to stand. However, in this scheme, since there is a large amount of mud at the bottom of the commercial concrete station slurry water, and the main recovery range is the clarified liquid part, the mud at the bottom will also consume a large amount of disinfectant, resulting in increased consumables costs and waste of disinfectants. On the other hand, conventional recovery devices cannot achieve continuous injection and discharge, and injecting disinfectants into flowing liquids will lead to differences in disinfection effects at different flow rates, and it is impossible to ensure that the disinfection effect is balanced and uniform at any time.

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] See also Figures 1 to 6The present invention provides the following technical solutions: a slurry water recovery device for a commercial concrete station, comprising a recovery device body, the recovery device body comprising a buffer tank 1, a purification and disinfection component 5, a floating component 7 and a disinfectant introduction mechanism 8, a flow guide mechanism 2 is inserted into the inner side of the buffer tank 1, a rotating shaft 28 is inserted into the surface of one side of the buffer tank 1, the bottom of the flow guide mechanism 2 is embedded in the interior of the rotating shaft 28, the other end of the rotating shaft 28 is screwed with a flow guide inclined pipe 3, the bottom end of the flow guide inclined pipe 3 is connected to the bottom end of the purification and disinfection component 5, the interior of the purification and disinfection component 5 is embedded with a floating component 7, the top of the floating component 7 is inserted with a plug-in pipe 23, the inner top of the purification and disinfection component 5 is welded with a disinfectant introduction mechanism 8, the top of the plug-in pipe 23 is embedded in the inner side of the disinfectant introduction mechanism 8, both sides of the purification and disinfection component 5 are integrally formed with discharge boxes 9, and the outer side of each of the discharge boxes 9 is plugged with a discharge pipe 11. The commercial concrete station slurry water recovery device is used for disinfecting and purifying the upper clarified solution part of the commercial concrete station slurry water.

[0028] When the present invention is used, the slurry water of the commercial concrete station to be recycled is injected into the interior from the top of the buffer tank 1, and then the clarified solution part of the top layer can be introduced into the purification and disinfection component 5 below through the guide mechanism 2. At this time, the slurry water part will flow upward from the bottom of the disinfection tank 6 until it flows to the bottom of the floating component 7, and can be mixed and contacted with the sprayed disinfectant part on the side of the positioning plate 21, and flow and continuously disinfect in the area between the positioning plate 21 and the first floating plate 17, and finally enter the interior of the discharge box 9 and be discharged to the outside. When it continues to the later stage of the recycling process, resulting in insufficient slurry water in the buffer tank 1, the rate at which the slurry water flows into the disinfection tank 6 will decrease. At this time, the floating component 7 moves downward, resulting in a synchronous decrease in the discharge speed of the discharge box 9, and the disinfectant introduction mechanism 8 at the top also reduces the disinfectant introduction rate, ultimately achieving the purpose of adaptive adjustment of the slurry water discharge and disinfectant injection rate.

[0029] In this embodiment, the purification and disinfection assembly 5 includes a disinfection tank 6 and a disinfectant box 14, the disinfectant box 14 is welded to the rear end of the disinfection tank 6, the top of the disinfectant box 14 is plugged with an intake pipe 13, the side bottom of the disinfection tank 6 is screwed with a docking sleeve 16, the top of the disinfection tank 6 is installed with a disinfectant delivery pump 12, the bottom of the buffer tank 1 is welded with a support plate 4, and the disinfection tank 6 is screwed on the surface of the support plate 4. The bottom of the diversion inclined pipe 3 is connected to the docking sleeve 16 through a flange, the surface of the disinfection tank 6 is provided with a discharge hole 10, and the internal cavity of the disinfection tank 6 is connected to the inside of the discharge box 9 on both sides through the discharge hole 10, the width of the discharge hole 10 gradually increases from the bottom to the top, the discharge pipes 11 outside the two discharge boxes 9 are connected to each other, and the end of the intake pipe 13 is connected to the disinfectant delivery pump 12 part. The upper clarified liquid portion is continuously introduced into the interior of the purification and disinfection component 5 through the buffer tank 1 in cooperation with the guide mechanism 2, so that the mud portion at the bottom layer does not consume a large amount of disinfectant, thereby reducing the amount of disinfectant used.

[0030] Specifically, the slurry water injected into the buffer tank 1 is guided by the diversion mechanism 2, and will flow from the bottom layer to the top layer after being transported to the inside of the disinfection tank 6, and disinfectant is only provided in the top area inside the disinfection tank 6 for disinfection treatment. Therefore, the whole process can avoid the mud part in the slurry water of the commercial concrete station from contacting with the disinfectant, and the disinfectant can also only disinfect the upper clarified solution part. After the disinfection is completed, it can be directly discharged to the outside from the side discharge box 9.

[0031] In this embodiment, the floating assembly 7 includes a first floating plate 17 and a positioning plate 21. A linkage pipe 19 is inserted in the middle of the first floating plate 17. A limiting plate 20 is integrally formed on the top of the linkage pipe 19. A plug-in pipe 23 is integrally formed on the top of the limiting plate 20. A side baffle 18 is welded to the side of the first floating plate 17. A connecting hole 27 is integrally formed on the bottom of the linkage pipe 19. A plurality of spray holes 22 are provided on the side of the connecting hole 27. The interiors of the positioning plate 21 and the linkage pipe 19 are both hollow structures, and the interior of the plug-in pipe 23 is connected to the interiors of the positioning plate 21 and the linkage pipe 19 after passing through the limiting plate 20. The side of the first floating plate 17 fits the inner wall of the sterilizing tank 6, and a gap is provided between the two sides of the positioning plate 21 and the inner wall of the sterilizing tank 6. Even if there is insufficient slurry water in the later stage, resulting in a decrease in water pressure and flow rate, the floating component 7 will move downward to reduce the discharge range of the discharge hole 10, and then the discharge speed will be reduced synchronously with the decrease in the front-end slurry water introduction speed. In addition, the disinfectant introduction mechanism 8 can also automatically adjust the injection amount of the disinfectant, so that after the slurry water injection rate decreases, the subsequent discharge and disinfectant injection rates are also reduced synchronously, thereby achieving the purpose of adaptive adjustment.

[0032] Specifically, after the slurry is injected into the interior of the disinfection tank 6 through the docking sleeve 16, the slurry will flow from the bottom to the top. In the floating assembly 7, the first floating plate 17 always pulls the linkage tube 19 upward through the limit plate 20, and the bottom of the linkage tube 19 pulls the positioning plate 21 upward, so that the first floating plate 17 always floats on the slurry surface inside the disinfection tank 6. Since the disinfectant introduction mechanism 8 at the top transports the disinfectant downward along the floating assembly 7 and finally sprays it out from the spray holes 22 on both sides of the positioning plate 21, the injected slurry will mix with the disinfectant on both sides of the positioning plate 21 during the upward flow, and finally be discharged from the discharge holes 10 on both sides after maintaining the flow state and mixing. Therefore, the mixing time of any injected slurry is the process of flowing from the positioning plate 21 to the bottom of the first floating plate 17, so that the proportion of disinfectant mixed with the slurry injected at any time during the entire disinfection process is fixed, and the disinfection effect is close.

[0033] In this embodiment, the disinfectant introduction mechanism 8 includes a shunt pipe 25 and a shunt bin 24. The top of the shunt bin 24 is plugged with a delivery pipe 15, and the other end of the delivery pipe 15 is connected to the disinfectant delivery pump 12. The side of the shunt bin 24 is connected with multiple shunt pipes 25. The end of each shunt pipe 25 is connected to a return pipe 26, and the other end of the return pipe 26 is connected to the inside of the disinfectant box 14. The top of the plug-in pipe 23 is provided with a connecting hole 27, and the surface of the plug-in pipe 23 is in contact with one side of the inner wall of the shunt bin 24, and the inside of the plug-in pipe 23 is connected to the internal cavity of the shunt bin 24 through the connecting hole 27. Specifically, the disinfectant is drawn out from the disinfectant tank 14, introduced into the delivery pipe 15 through the disinfectant delivery pump 12, and finally injected into the diversion chamber 24, where it flows through each connected diversion pipe 25 and the plug-in pipe 23 at the bottom. When the amount of injected slurry water decreases, the floating assembly 7 connected to the plug-in pipe 23 decreases, and the number of exposed diversion pipes 25 increases, which will cause the amount of disinfectant flowing into the plug-in pipe 23 to decrease, thereby realizing the automatic adjustment function of the disinfectant according to the amount of flowing slurry water.

[0034] In this embodiment, the diversion mechanism 2 includes a second floating plate 32 and a rotating sleeve 29, the bottom of the rotating sleeve 29 is inserted into the inner side of the rotating shaft 28, the top of the rotating sleeve 29 is connected with an introduction sleeve 31 through a flange, and the surface of the introduction sleeve 31 is sleeved with a rotating ring 30. The top of the rotating ring 30 is integrally formed with a support plate 33, the second floating plate 32 is integrally formed at the top of the support plate 33, and the second floating plate 32 and the support plate 33 rotate around the introduction sleeve 31 through the rotating ring 30, and a gap is provided between the surface of the rotating sleeve 29 and the inner wall of the buffer tank 1. It can achieve continuous injection and discharge, and the upper layer of the clarified liquid slurry water of a fixed depth can always be diverted by the diversion mechanism 2, so that the injected water pressure can be kept constant, and the conveying flow rate of the slurry water remains unchanged, and finally the disinfection time and disinfection effect of the commercial concrete station slurry water in any period are consistent and balanced. At the same time, it can also automatically stop conveying when the slurry water is insufficient. Specifically, by keeping the second float plate 32 always floating on the surface of the slurry, the supporting plate 33 can be used to pull the rotating ring 30 at the bottom to ensure that the inlet sleeve 31 is always at a fixed depth position at the bottom of the slurry, and the slurry at this position is passed through the rotating sleeve 29 through the rotating shaft 28, and finally flows into the interior of the disinfection tank 6 along the diversion inclined pipe 3 to complete the subsequent disinfection process.
