TECHNICAL FIELD

[0001] The utility model relates to water treatment technical field, concretely relates to improve the flocculation effect device of perforated cyclone reaction pool. BACKGROUND

[0002] Raw water flocculation is a kind of water treatment process, mainly used to remove suspended solids, colloids and fine particles in water to improve the clarity and quality of water.Perforated cyclone flocculation reaction pool is an important equipment for water treatment, and the reaction pool includes a pool body, a water inlet pipe and a water outlet pipe are arranged on the pool body, and a sludge discharge pipe is connected to the bottom of the pool body.When water treatment, water enters the pool body through the water inlet pipe, and a coagulant is added to the pool body, and the smaller particles in the water form large particles of sediment under the action of the coagulant after flocculation, and then the liquid is discharged through the water outlet pipe to realize solid-liquid separation and water purification.

[0003] After the sediment settles to the bottom of the pool, it is discharged through the sludge discharge pipe. However, using this way to clean the sediment, due to the limited pipe diameter of the sludge discharge pipe, combined with the poor flowability of the sediment, the sediment is easily blocked in the sludge discharge pipe, especially in the horizontal straight part and the elbow part of the sludge discharge pipe, which affects the normal sludge discharge. In this way, the sediment cannot be normally discharged or the sediment in the pool body cannot be completely discharged, and the pool contains a lot of impurities, which are mixed in the water, and affect the subsequent flocculation effect of the water. CONTENT OF THE UTILITY MODEL

[0004] The utility model intends to provide improve the flocculation effect device of perforated cyclone reaction pool to abandon the way of sludge discharge through sludge discharge pipe to clean the sediment, improve the cleaning efficiency of the sediment in the pool body and improve the flocculation effect of the reaction pool.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: improve the flocculation effect device of perforated cyclone reaction pool, including cleaning unit, the cleaning unit includes filter plate, bottom plate and vertical rod, filter plate is located in the upper of bottom plate, and bottom plate and vertical rod are fixedly connected, vertical rod passes through filter plate, and vertical rod and filter plate are slidably connected.

[0006] The principle and advantages of the application scheme are: the device in the application is placed in the pool cavity of the reaction pool, raw water is introduced into the pool body, water enters the pool cavity at the position between the filter plate and the bottom plate, and the precipitate is settled between the bottom plate and the filter plate. At the same time, the water can flow upwards through the filter plate, and the filter plate plays a filtering role on the precipitate, so as to intercept the precipitate between the filter plate and the bottom plate. In this way, the precipitate generated in the pool cavity is located between the filter plate and the bottom plate. When it is necessary to clean the precipitate in the pool cavity, the vertical rod is pulled upwards, the vertical rod drives the bottom plate to move upwards, the bottom plate drives the precipitate to move upwards together, and when the precipitate on the bottom plate abuts against the filter plate, the precipitate is clamped by the filter plate and the bottom plate, and the bottom plate, the filter plate and the clamped precipitate move upwards together. When the cleaning unit is pulled out of the pool cavity, the precipitate between the filter plate and the bottom plate is also pulled out, so that the precipitate in the pool cavity can be quickly treated, the pool body does not need to be designed with a sewage discharge pipe for discharging the precipitate, the efficiency of discharging sewage is improved, the problem of blockage of the sewage discharge pipe does not occur, and the continuous and normal flocculation can be ensured, which is beneficial to ensuring the effect of flocculation.

[0007] At the same time, the precipitate in the pool cavity will be deposited on the bottom plate, and the precipitate can be pulled out of the pool cavity by pulling the bottom plate upwards, so that the problem of cleaning dead angle caused by the precipitate being located in a large area at the bottom of the pool cavity can be avoided.

[0008] After the cleaning unit in the scheme cleans the precipitate in the pool cavity, the amount of precipitate in the pool cavity is reduced, the inside of the pool cavity is relatively clean, and after the amount of precipitate is reduced, the internal space of the pool cavity is increased, so that more water can be accommodated, thereby being beneficial to improving the effect of subsequent flocculation of water.

[0009] Preferably, as an improvement, the cleaning unit has a plurality of vertical rods, a connecting portion is fixed between the plurality of vertical rods, and a lifting portion is arranged on the connecting portion.

[0010] Therefore, the cleaning unit has a plurality of cleaning units, which can clean a plurality of pool cavities at the same time, and the connecting portion connects the plurality of cleaning units. By lifting the lifting portion, the connecting portion drives the plurality of vertical rods to move upwards, so that the plurality of cleaning units in the plurality of pool cavities can be pulled upwards at the same time, the dirt in the plurality of pool cavities can be cleaned at the same time, and the efficiency of cleaning is improved.

[0011] Preferably, as an improvement, the connecting portion is a connecting plate, the lifting portion is a lifting plate, and a lifting hole is arranged on the lifting plate.

[0012] Preferably, as an improvement, the filter plate is fixedly connected with a clamping block, and the clamping block is located at the edge of the filter plate.

[0013] Thus, the inner wall of the pool cavity is provided with a clamping groove matched with the clamping block, and the clamping block and the bottom end of the clamping groove abut, thereby playing a limiting role on the filter plate. The filter plate in the pool cavity will not fall to the bottom plate under the action of gravity, so that the bottom plate and the filter plate have a storage space for the sediments.

[0014] Preferably, as an improvement, the filter plate is provided with a rod hole, the vertical rod passes through the rod hole, and a transverse limiting component is arranged between the vertical rod and the rod hole.

[0015] Thus, by arranging the transverse limiting component, the relative rotation of the filter plate and the vertical rod can be avoided, so that the filter plate, the vertical rod and the bottom plate can be in a stable state without relative rotation, which is conducive to improving the stability of the lifting process of the cleaning unit.

[0016] Preferably, as an improvement, the vertical rod is provided with a vertical limiting groove, and a limiting block is fixedly arranged on the inner wall of the rod hole and located in the limiting groove; or,

[0017] A vertical limiting block is fixedly arranged on the vertical rod, and a limiting groove is arranged on the inner wall of the rod hole, and the limiting block is located in the limiting groove.

[0018] Preferably, as an improvement, the bottom plate is provided with a filter hole. The arrangement of the filter hole can make the water in the pool cavity infiltrate into the pool cavity through the filter hole during the upward movement of the bottom plate to pull up the sediments, thereby avoiding the cleaning unit carrying out more water.

[0019] Preferably, as an improvement, the bottom plate is square, circular or polygonal in shape, and the bottom plate and the filter plate are the same in shape. Thus, the bottom plate and the filter plate are arranged in different shapes according to the different shapes of the pool cavity.

[0020] Preferably, as an improvement, the vertical rod is located in the middle of the bottom plate, and the vertical rod passes through the middle of the filter plate. Thus, the center of gravity of the cleaning unit is in the middle (the center of gravity of the cleaning unit is located on the straight line where the vertical rod is located), and the cleaning unit will not be side-tilted during the lifting process, so that the lifting process is more stable.

[0021] Preferably, as an improvement, the number of the cleaning units is 3-8. Thus, the cleaning units are arranged in 3-8 according to the different number of the pool cavity.

[0022] To achieve the above object, the utility model discloses another lower technical scheme: perforated cyclone reaction pool, including pool body, be equipped with a plurality of top opening pool cavity in pool body, a plurality of pool cavities are communicated in turn, the pool cavity of pool body one end is connected with inlet pipe, the pool cavity of pool body other end is connected with outlet pipe, be equipped with lifting perforated cyclone reaction pool flocculation effect device in pool cavity, lifting perforated cyclone reaction pool flocculation effect device all includes cleaning unit, and cleaning unit all includes filter plate, bottom plate and vertical rod, filter plate is located the top of bottom plate, and the space for depositing is between filter plate and bottom plate, and bottom plate and vertical rod fixed connection, and vertical rod passes through filter plate, and vertical rod and filter plate sliding connection;

[0023] The connecting part of the inlet pipe and the pool body is arranged between the filter plate and the bottom plate.

[0024] The principle and advantages of the present application are as follows: the plurality of pool cavities in the present application are communicated in turn, so that the water entering from the inlet pipe enters the pool cavity at one end of the pool body, and then enters the other pool cavities through the channel in turn, and finally the water is discharged through the outlet pipe of the pool cavity at the other end of the pool body after flocculation and purification.

[0025] Since the connecting part of the inlet pipe and the pool body is arranged between the filter plate and the bottom plate, the water entering from the inlet pipe first enters between the filter plate and the bottom plate, and the coagulant and water react in the space between the filter plate and the bottom plate. After the reaction, the generated sediment is located in the sediment storage space between the filter plate and the bottom plate. Then the water flows upward through the filter plate, which plays a filtering role on the sediment, thereby intercepting the sediment between the filter plate and the bottom plate. The upward flowing water enters the channel through the liquid inlet of the channel and flows into the next pool cavity from the liquid outlet of the channel. Since the liquid outlet of the channel is located between the filter plate and the bottom plate of the other pool cavity, the liquid flowing out of the liquid outlet of the channel also enters between the filter plate and the bottom plate first. The water that is not completely purified in the previous pool cavity continues to be purified in this pool cavity, and the generated sediment is located between the filter plate and the bottom plate of the pool cavity. At the same time, the water continues to flow upward and flows into the next pool cavity through the channel, and so on, to complete the purification of the water. During the entire water purification process, the filter plate in the pool cavity plays a filtering role on the sediment in the upward flowing water, thereby intercepting the sediment between the filter plate and the bottom plate. Therefore, the water flows in different pool cavities, thereby realizing step-by-step purification of the water.

[0026] Through the above process, it can be known that the sediment generated in the pool cavity is located between the filter plate and the bottom plate. When it is necessary to clean the sediment in the pool cavity, the vertical rod is pulled upward, the vertical rod drives the bottom plate to move upward, the bottom plate drives the sediment to move upward together, when the sediment on the bottom plate abuts against the filter plate, the sediment is clamped by the filter plate and the bottom plate, and the bottom plate, the filter plate and the clamped sediment move upward together. When the cleaning unit is taken out of the pool cavity, the sediment located between the filter plate and the bottom plate is also taken out together, so that the sediment in the pool cavity is quickly treated, and the pool body does not need to be designed with a sewage discharge pipe for discharging sludge, flocculent sediment and other pollutants, the efficiency of sewage discharge is improved, and the problem of blockage of the sewage discharge pipe does not occur.

[0027] At the same time, the sediment in the pool cavity will deposit on the bottom, and the sediment is pulled out of the pool cavity by pulling the bottom plate upward, so that the problem of cleaning dead angle caused by the large-area sediment on the bottom of the pool cavity and the incomplete cleaning of sludge can be avoided.

[0028] The present application can clean the sediment in the reaction pool, reduce the sediment in the reaction pool, and improve the water storage space in the pool cavity and the subsequent flocculation effect of water.

[0029] Preferably, as an improvement, the vertical rod extends upward to the top of the pool body, a connecting portion is fixed between the plurality of vertical rods, and a lifting portion is arranged on the connecting portion. Thus, by lifting the lifting portion, the connecting portion drives the plurality of vertical rods to move upward, so that the plurality of cleaning units in the plurality of pool cavities are pulled upward at the same time, the simultaneous cleaning of the pollutants in the plurality of pool cavities is realized, and the cleaning efficiency is improved.

[0030] Preferably, as an improvement, the connecting portion is a connecting plate, and the lifting portion is a lifting plate, and the lifting plate is provided with a lifting hole.

[0031] Preferably, as an improvement, the inner wall of the pool cavity is provided with a vertical clamping groove, the top end of the clamping groove extends to the top of the pool body; a clamping block is fixedly connected to the filter plate and is slidingly arranged in the clamping groove; and the clamping block abuts against the bottom end of the clamping groove when the filter plate is located in the pool cavity.

[0032] Thus, by abutting the clamping block against the bottom end of the clamping groove, the limiting effect of the filter plate is achieved, the filter plate will not fall onto the bottom plate under the action of gravity when the filter plate is located in the pool cavity, and the sediment storage space is provided between the bottom plate and the filter plate. The top end of the clamping groove extends to the top of the pool body, so that the clamping block can enter from the top end of the clamping groove when the filter plate is lowered into the pool cavity.

[0033] Preferably, as an improvement, the connecting portion of the water outlet pipe and the pool body is located above the filter plate. Thus, when the water outlet pipe discharges water, the water moves upward from below to flow through the filter plate, and the filter plate plays a filtering role on the water, so that the water entering the water outlet pipe is cleaner.

[0034] Preferably, as an improvement, the bottom of the pool cavity is provided with a drainage pipe. In the present application, the pool body is always filled with water during normal use, and the water flows in the pool cavity. When it is necessary to empty the water in the pool cavity (for example, when the pool cavity needs to be cleaned and maintained to a large extent), the water in the pool cavity can be drained out through the drainage pipe, solving the problem that the water in the pool cavity cannot be drained.

[0035] Preferably, as an improvement, the drainage pipe comprises a drainage branch pipe and a drainage main pipe, the drainage branch pipe is connected with the bottom of the pool cavity, and the drainage branch pipe is connected with the drainage main pipe.

The arrangement of the filter holes can make the water in the pool cavity infiltrate into the pool cavity through the filter holes during the process of upward movement of the bottom plate to pull up the sediment, avoiding that the cleaning unit carries out too much water.

[0039] Preferably, as an improvement, the number of pool cavities is 3-8. BRIEF DESCRIPTION OF DRAWINGS

[0045] The embodiments are basically as shown in the accompanying drawings Figures 1-2As shown: perforated cyclone reaction pool, including pool body 1, pool body 1 can be cement material, also can be steel material, pool body 1 is equipped with multiple pool cavities 2 with top opening, the number of pool cavities 2 is 3-8, the number of pool cavities 2 in the figure in the embodiment is four. Multiple pool cavities 2 are arranged from left to right, the shape of the inner wall of the pool cavity 2 can be square, circular or polygonal, the shape of the pool cavity 2 in the figure in the embodiment is square.

[0046] Adjacent pool cavities 2 are communicated, and the specific communication mode is that a partition plate is arranged between adjacent pool cavities 2, the partition plate is vertically arranged, the partition plate separates the two adjacent pool cavities 2, and the partition plate is internally provided with a channel 12. The liquid inlet 10 of the channel 12 is located above the liquid outlet 11 of the channel 12. The liquid inlet 10 of the channel 12 and the left pool cavity 2 of the two adjacent pool cavities 2 are communicated, and the liquid outlet 11 of the channel 12 and the right pool cavity 2 of the two adjacent pool cavities 2 are communicated.

[0047] The leftmost pool cavity 2 is connected with a water inlet pipe 3, and the rightmost pool cavity 2 is connected with a water outlet pipe 4. The pool cavity 2 is provided with a lifting perforated cyclone reaction pool flocculation effect device, and the lifting perforated cyclone reaction pool flocculation effect device in the embodiment comprises a cleaning unit. The cleaning unit in the embodiment comprises a filter plate 5, a bottom plate 6 and a vertical rod 7. The filter plate 5 is located above the bottom plate 6 and can be fixed in the pool cavity 2. The filter plate 5 is not attached to the bottom plate 6. The implementation mode that the filter plate 5 is fixed on the inner wall of the pool cavity 2 without falling is that the front and rear inner walls of the pool cavity 2 are both provided with vertical clamping grooves, and the top end of the clamping groove extends to the top of the pool body 1. The filter plate 5 is fixedly connected (for example, welded) with a clamping block 15. The clamping block 15 is inserted from the top end of the clamping groove and slides downward to the bottom end. The clamping block 15 is slidably arranged in the clamping groove. When the filter plate 5 is located in the pool cavity 2, the clamping block 15 abuts against the bottom end of the clamping groove. In the embodiment, the bottom of the clamping groove is located at one third of the pool cavity from the top of the pool cavity downward. Thus, the filter plate 5 is fixed in the pool cavity 2 without falling by abutting the clamping block 15 against the bottom end of the clamping groove. In the embodiment, the space between the filter plate 5 and the bottom plate 6 is a sediment storage space. The middle part of the bottom plate 6 is fixedly connected with the vertical rod 7. The middle part of the filter plate 5 is provided with a vertical rod hole. The vertical rod 7 passes through the rod hole of the filter plate 5, and the vertical rod 7 is slidably connected with the filter plate 5. The bottom plate 6 is located at the bottom of the pool cavity 2. The top end of the vertical rod 7 is located above the top of the pool body 1. The filter plate 5 is provided with a filter hole. In the embodiment, the filter holes of the filter plates 5 of different pool cavities 2 can be the same or different.

[0048] In order to improve the connection stability of the filter plate 5 and the vertical rod 7, in some embodiments, a horizontal limiting component is arranged between the vertical rod 7 and the rod hole. Specifically, in combination with Figure 3As shown, the transverse limiting component in the embodiment includes a limiting block 16 fixedly welded on the vertical rod 7 and a limiting groove on the inner wall of the rod hole. After the vertical rod 7 passes through the rod hole, the limiting block 16 is located in the limiting groove and can slide in the limiting groove. Thus, the filter plate 5 and the vertical rod 7 cannot rotate relative to each other due to the clamping of the limiting block 16 and the limiting groove. Of course, in other embodiments, the limiting groove can be located on the vertical rod 7 and the limiting block 16 can be welded on the inner wall of the rod hole.

[0049] In the embodiment, the vertical rods 7 on the plurality of cleaning units are connected by a connecting part 8. The connecting part 8 is a connecting plate, and the specific connection between the connecting plate and the vertical rod 7 can be welding or fixed connection by bolts. The connecting part 8 is provided with a lifting part 9. The lifting part 9 in the embodiment is a lifting plate, the lifting part 9 and the connecting part 8 are welded, and the lifting plate is provided with a lifting hole, so that the steel wire rope can pass through the lifting hole to connect with the lifting plate.

[0050] In the embodiment, the connecting part between the water inlet pipe 3 and the leftmost pool body 1 is arranged between the filter plate 5 and the bottom plate 6; the inlet 10 of the channel 12 between the adjacent pool cavities 2 is located above the filter plate 5 of the left pool cavity 2, and the outlet 11 of the channel 12 is located between the filter plate 5 and the bottom plate 6 of the right pool cavity 2. The connecting part between the water outlet pipe 4 and the pool body 1 is located above the filter plate 5 in the rightmost pool cavity 2.

[0051] The water purification process of the reaction pool in the embodiment is as follows: water enters the leftmost pool cavity 2 from the water inlet pipe 3, a coagulant is added into the pool cavity 2, the coagulant and the water react in the space between the bottom plate 6 and the filter plate 5, and after the reaction, flocculation is generated and located between the bottom plate 6 and the filter plate 5. At the same time, the water flows upward, and the sediment in the water is intercepted by the filter plate 5, the sediment is located between the filter plate 5 and the bottom plate 6, and the water passing through the filter plate 5 enters the inlet 10 of the channel 12 and flows into the right pool cavity 2 from the outlet 11 of the channel 12.

[0052] Similarly, a flocculating agent is added into the second pool cavity 2, the water entering the second pool cavity 2 reacts with the coagulant to further purify the water, and after the water flows upward through the filter plate 5, it enters the inlet 10 of the channel 12 and flows into the third pool cavity 2 from the outlet 11 of the channel 12. The sediment in the second pool cavity 2 remains between the filter plate 5 and the bottom plate 6.

[0053] By analogy, the water passes through each pool cavity 2, each pool cavity 2 purifies the water, and the sediment generated in each pool cavity 2 remains between the filter plate 5 and the bottom plate 6. Finally, the water flows upward through the rightmost filter plate 5 and is discharged from the water outlet pipe 4.

[0054] When the reaction tank is used for a period of time, the sediment between the filter plate 5 and the bottom plate 6 in the tank cavity 2 needs to be treated. The treatment method is as follows: using a lifting device (such as a crane) to lift the steel wire rope upwards, the lifting plate drives the connecting plate to move upwards, the connecting plate drives the four vertical rods 7 to move upwards together, the vertical rods 7 drive the bottom plate 6 to move upwards, and when the bottom of the filter plate 5 abuts against the sediment, the filter plate 5 is pressed on the sediment on the bottom plate 6 under the action of gravity, the sediment between the bottom plate 6 and the filter plate 5 is clamped by the filter plate 5 and the bottom plate 6, and the filter plate 5 and the bottom plate 6 clamp the sediment to move upwards together. Finally, the cleaning unit is taken out of the tank cavity 2, and the filter plate 5 and the bottom plate 6 clamp the sediment to move out together. During the transfer of the crane to the cleaning unit outside the tank body 1, the sediment will not fall off the bottom plate 6 under the clamping action of the bottom plate 6 and the filter plate 5, and the sediment is relatively stable during the transfer.

[0055] Then the crane lifts the cleaning unit to the unloading position (such as a special sludge storage place or a garbage cleaning vehicle), and lays down the cleaning unit (the vertical rods 7 change from vertical to horizontal), and the sediment in the cleaning unit falls out from between the filter plate 5 and the bottom plate 6.

[0056] After the sediment is cleaned, the crane is used to lift the cleaning unit into the tank cavity 2 again, and the cleaning unit is laid down. The bottom plate 6 and the filter plate 5 move downwards, and during the downward movement of the filter plate 5, the clamping block is laid down into the clamping groove and slides downwards in the clamping groove. When the clamping block abuts against the bottom end of the clamping groove, the filter plate 5 stops moving downwards, and the bottom plate 6 continues to move downwards, so that a sediment storage space is formed between the bottom plate 6 and the filter plate 5.

[0057] The sediment in the tank cavity 2 is cleaned in the manner of the present application, and there is no need to design a sewage discharge pipe for discharging sludge, flocculent sediment and other pollutants, thereby improving the sewage discharge efficiency and avoiding the problem of blockage of the sewage discharge pipe.

[0058] In addition, the sediment in the tank cavity 2 in the embodiment is deposited on the bottom plate 6, and the sediment is lifted out of the tank cavity 2 by pulling the bottom plate 6 upwards, thereby avoiding the problem of cleaning dead angles caused by the fact that too much sediment is located at the bottom of the tank cavity 2 (the position below the bottom plate 6) and cannot be cleaned.

[0059] In the embodiment, the cleaning effect of the sediment is improved, the tank cavity is relatively clean, and the subsequent flocculation effect of water is guaranteed and improved.

[0060] In this embodiment, water will always remain in the pool chamber 2 during the water circulation process. Although the cleaning unit in this embodiment can remove sediment from the pool chamber 2, it cannot guarantee a completely thorough cleaning every time. Therefore, over time, some sediment will still remain inside the pool chamber 2. Thus, after a period of time, a major cleaning of the pool chamber 2 is required for a complete clean, during which the water in the pool chamber 2 needs to be drained. To facilitate the drainage of water from the pool chamber 2, this embodiment combines... Figure 1 As shown, the bottom of the pool chamber 2 is equipped with a drainage pipe fitting. The drainage pipe fitting includes drainage branch pipes 13 and a main drainage pipe 14. There are multiple drainage branch pipes 13, one of which is connected to the bottom of each pool chamber 2. The bottom ends of multiple drainage branch pipes 13 are connected to the same main drainage pipe 14. A valve is installed on the drainage pipe fitting (either the drainage branch pipe 13 or the main drainage pipe 14). Normally, the valve is closed, and water in the pool chamber 2 is not discharged. When a major cleaning of the pool chamber 2 is required, the valve is opened, and water in the pool chamber 2 flows through the drainage branch pipes 13 into the main drainage pipe 14. The water is then discharged from the main drainage pipe 14 to other locations, thus draining the water from the pool chamber 2, exposing the inner wall of the pool chamber 2, and then cleaning the accumulated sludge, flocculent sediment, and other contaminants in the pool chamber 2.

[0061] In other embodiments, the bottom plate 6 may also be provided with filter holes, so that the bottom plate 6 will not obstruct the water during the upward lifting of the cleaning unit, and the water in the pool cavity 2 will seep into the pool cavity 2 through the filter holes on the bottom plate 6, thus avoiding the cleaning unit from bringing out too much water during the process of scooping out the sediment.

[0062] Combination Figure 2 As shown, in this embodiment, the direction of the inlet pipe 3 is close to the inner wall of the pool cavity 2 and parallel to the inner wall of the pool cavity 2. The outlet 11 of the channel 12 is close to the inner wall of the pool cavity 2 and parallel to the inner wall of the pool cavity 2. In this way, the liquid flowing out from the outlet 11 or the liquid flowing out from the inlet pipe 3 impacts the water in the pool cavity 2 along the inner wall of the pool cavity 2, which is more conducive to the formation of vortex in the pool cavity 2, so that more effective collisions are generated between the flocs and the flocculation efficiency is improved.
