Description

Technical Field

[0001] This utility model relates to the field of ultrafiltration concentrate reuse technology, and in particular to an ultrafiltration concentrate reuse system for demineralized water stations. Background Technology

[0002] Concentrated water refers to wastewater with high salt content and high conductivity generated during the process of producing pure water through RO membrane reverse osmosis technology. With the rapid development of industry, the demand for pure water in industrial production has increased, and the corresponding concentrated water has also surged. In the current technology, when recycling concentrated water, a concentrated water tank is usually built, and a pump is used to introduce it into the raw water tank or the inlet of the mechanical filter at the front end of the system to achieve water recycling.

[0003] To prevent pipe blockage and strong impact loads from fixed substances in existing concentrate tanks, agitation and other measures are usually adopted to prevent fixed substances from settling to the bottom and to keep them in a suspended and uniformly distributed state, thus avoiding excessively high local concentrations. Although this alleviates the impact load to some extent, impurities such as flocculation are not reduced and will continue to accumulate during continuous circulation, increasing the system load. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology. In order to avoid pipe blockage and strong impact loads from fixed substances in the existing concentrate tank, stirring and other measures are usually adopted to prevent the fixed substances in the concentrate tank from settling to the bottom and keep them in a suspended and uniformly distributed state to avoid excessively high local concentrations. Although the impact load is alleviated to a certain extent, impurities such as flocculation are not reduced and will continue to accumulate in the continuous circulation, increasing the system load. Therefore, this utility model proposes an ultrafiltration concentrate reuse system for demineralized water stations.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A demineralized water station ultrafiltration concentrate reuse system includes a base and a concentrate tank, wherein the concentrate tank is fixedly connected to the inner side wall of the base; The base is equipped with an adjustment mechanism, which includes a conical tube, a U-shaped plate, an extraction cavity, and an extraction plate. The conical tube is fixedly connected to the lower end face of the concentrate tank, the U-shaped plate is slidably connected to the side wall of the concentrate tank, and the U-shaped plate is slidably connected to the lower end face of the conical tube. The extraction cavity is fixedly connected to the side wall of the concentrate tank, and the extraction plate is slidably connected to the side wall of the extraction cavity.

[0006] Preferably, a pulling rod is fixedly connected to the side wall of the pulling plate, and a receiving cavity is formed on the inner side wall of the pulling rod, and an adjusting plate is slidably connected to the inner side wall of the receiving cavity.

[0007] Preferably, an adjusting rod is fixedly connected between the adjusting plate and the U-shaped plate, and the adjusting rod is slidably connected to the side wall of the extraction rod.

[0008] Preferably, a spray ring is fixedly connected to the inner wall of the tapered tube, and baffles are fixedly connected to both ends of the inner wall of the base.

[0009] Preferably, an inlet pipe is fixedly connected between the extraction chamber and the concentrate tank, and an outlet pipe is fixedly connected between the extraction chamber and the spray ring. Both the inlet pipe and the outlet pipe are equipped with a one-way valve.

[0010] Preferably, an electric push rod is fixedly connected to the inner side wall of the base, and the telescopic end of the electric push rod is fixedly connected to the U-shaped plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: By combining the extraction chamber, U-shaped plate, spray ring and other structures, the ultrafiltration concentrate in the concentrate tank is allowed to settle and settle. The U-shaped plate is used to separate the upper clear liquid from the lower sludge containing a large amount of impurities. Then, the ultrafiltration concentrate with a large amount of sediment in the lower layer is discharged into the wastewater tank, and the upper clear liquid is extracted to flush the bottom of the conical tube. Most of the solid impurities are removed in each cycle, avoiding continuous accumulation during the cycle and increasing the system load. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0016] Reference Figures 1-4 A demineralized water station ultrafiltration concentrate reuse system includes a base 1 and a concentrate tank 2. The concentrate tank 2 is fixedly connected to the inner wall of the base 1. The concentrate tank 2 has a small volume to avoid overloading the components. The base 1 is equipped with an adjustment mechanism, which includes a conical tube 3, a U-shaped plate 4, an extraction chamber 5, and an extraction plate 6. The conical tube 3 is fixedly connected to the lower end face of the concentrate tank 2. The inner wall of the conical tube 3 is relatively smooth, and the side walls are all inclined. The inclination angle makes it easiest for impurities to slide down under their own gravity. The U-shaped plate 4 is sealed and slidably connected to the side wall of the concentrate tank 2. The U-shaped plate 4 is sealed and slidably connected to the lower end face of the conical tube 3. The U-shaped plate 4 is relatively thick and heavy, and notches are opened on the upper and lower end faces. The inner wall of the base 1 is fixedly connected to the conical tube 3. An electric push rod 14 is connected, and the telescopic end of the electric push rod 14 is fixedly connected to the U-shaped plate 4. The bottom end of the concentrate tank 2 is provided with a sliding groove. The upper end face of the U-shaped plate 4 is slidably connected in the sliding groove. When the electric push rod 14 is retracted inside, the notch on the upper end face of the U-shaped plate 4 overlaps with the concentrate tank 2. The lower end face of the U-shaped plate 4 seals the lower end face of the conical tube 3. At this time, the conical tube 3 and the concentrate tank 2 are connected. When the electric push rod 14 is extended and moves the U-shaped plate 4 forward, the upper end face of the U-shaped plate 4 gradually seals and separates the concentrate tank 2 from the conical tube 3. After the bottom of the concentrate tank 2 is completely sealed, the seal on the bottom of the conical tube 3 is released. The extraction chamber 5 is fixedly connected to the side wall of the concentrate tank 2, and the extraction plate 6 is slidably connected to the side wall of the extraction chamber 5.

[0017] Reference Figure 4 A pulling rod 7 is fixedly connected to the side wall of the pulling plate 6. A receiving cavity is opened on the inner side wall of the pulling rod 7. An adjusting plate 8 is slidably connected to the inner side wall of the receiving cavity. An adjusting rod 9 is fixedly connected between the adjusting plate 8 and the U-shaped plate 4. The adjusting rod 9 is slidably connected to the side wall of the pulling rod 7. The friction between the adjusting plate 8, the adjusting rod 9 and the pulling rod 7 is very small.

[0018] Reference Figure 1A spray ring 10 is fixedly connected to the inner wall of the conical tube 3. The spray ring 10 is an annular anti-clogging nozzle that sprays the clean concentrated water delivered from the extraction chamber 5 along the inner wall of the conical tube 3 at a certain pressure to clean the inner wall of the conical tube 3. Baffles 11 are fixedly connected to both ends of the inner wall of the base 1. The lower end face of the conical tube 3 is directly facing the opening between the two baffles 11. The two baffles 11 and the base 1 together form a wastewater pool. The ultrafiltration concentrated water containing a large number of impurities enters the wastewater pool and is then introduced into the treatment system for deep treatment instead of entering the circulation system.

[0019] Reference Figure 4 An inlet pipe 12 is fixedly connected between the extraction chamber 5 and the concentrate tank 2, and an outlet pipe 13 is fixedly connected between the extraction chamber 5 and the spray ring 10. Both the inlet pipe 12 and the outlet pipe 13 are equipped with one-way valves. The flow direction of the one-way valve in the inlet pipe 12 is from the concentrate tank 2 to the extraction chamber 5, and the flow direction of the one-way valve in the outlet pipe 13 is from the extraction chamber 5 to the spray ring 10. The inlet of the inlet pipe 12 away from the extraction chamber 5 is located above the concentrate tank 2, that is, the cleanest concentrate is drawn in for rinsing.

[0020] In this invention, the ultrafiltration concentrate is first introduced into the concentrate tank 2 and left to stand for a period of time to allow the fixed substances to settle into the conical tube 3 at the bottom. Then, the electric push rod 14 is activated to move the U-shaped plate 4 forward, causing the upper notch of the U-shaped plate 4 to move outside the concentrate tank 2. When the upper part of the U-shaped plate 4 completely seals the bottom of the concentrate tank 2, the lower notch of the U-shaped plate 4 begins to move to the bottom of the conical tube 3, releasing the seal on the bottom of the conical tube 3. At this time, the ultrafiltration concentrate containing a large amount of sediment falls from the bottom of the conical tube 3 under the action of gravity, falling between the two baffles 11 to the bottom of the base 1 and into the wastewater tank.

[0021] When the U-shaped plate 4 moves forward, it squeezes the adjusting rod 9 and the adjusting plate 8. Since the friction between the adjusting plate 8, the adjusting rod 9 and the extraction rod 7 is very small, the extraction rod 7 remains stationary. The adjusting rod 9 and the adjusting plate 8 slide inside the extraction rod 7 until the notch below the U-shaped plate 4 begins to move to the bottom of the conical tube 3, so that the ultrafiltration concentrate containing a large amount of sediment in the conical tube 3 is almost automatically drained. Only then does the adjusting plate 8 contact the end of the inner cavity of the extraction rod 7, thereby pushing the extraction rod 7 and the extraction plate 6 forward. The one-way valve in the inlet pipe 12 closes and the one-way valve in the outlet pipe 13 opens. The clean concentrate in the extraction cavity 5 enters the spray ring 10 along the outlet pipe 13, flushing the inner wall of the conical tube 3 and washing down a small amount of stubborn solid sediment, keeping the inner wall of the conical tube 3 clean.

[0022] The ultrafiltration concentrate containing a large amount of sediment and impurities is introduced into the wastewater tank. Then, the electric push rod 14 is activated to retract, causing the U-shaped plate 4 to reset. The U-shaped plate 4 first resets to seal the bottom of the conical tube 3, and then releases the seal on the concentrate tank 2. At this time, the adjusting plate 8 moves to the end of the extraction plate 6, pulling the extraction rod 7 and the extraction plate 6 away from the extraction chamber 5. The one-way valve in the inlet pipe 12 opens, and the one-way valve in the outlet pipe 13 closes. The uppermost layer of concentrate tank 2, containing the fewest impurities and the cleanest part, enters the extraction chamber 5 through the inlet pipe 12. Then, the pump introduces the concentrate with almost no impurities into the front end of the system for circulation. In each circulation, most of the solid impurities are removed, preventing them from accumulating continuously and increasing the system load.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
