[0029] The mixing kettle 2 is installed on the upper end of the base 4. The mixing kettle 2 has a first liquid inlet, a second liquid inlet and a liquid outlet. The first liquid inlet of the mixing kettle 2 is connected to the liquid inlet pipe 1, and the second liquid inlet of the mixing kettle 2 is connected to the liquid storage tank 8 storing the coagulant. A stirring mechanism 9 is provided in the mixing kettle 2.

The other side of the liquid outlet of the mixing kettle 2 is connected to a connecting pipe 14, and the connecting pipe 14 is connected to a pump body. The connecting pipe 14 is located on the outside of the mixing kettle 2. The mixing kettle 2 is located directly above the receiving barrel 24. The mixing kettle 2 and the receiving barrel 24 are blocked by a slide plate 17. When the slide plate 17 slides away, the mixing kettle 2 is connected to the receiving barrel 24.

[0030] The liquid accumulation kettle 10 has a feed inlet and a discharge port. The feed inlet of the liquid accumulation kettle 10 is connected to the liquid discharge port of the mixing kettle 2 through a connecting pipe 14. The discharge port of the liquid accumulation kettle 10 is located at the bottom of the liquid accumulation kettle 10 and is provided with an openable and closable baffle 11. The side of the liquid accumulation kettle 10 facing the mixing kettle 2 is fixedly connected with a slide plate 17. The hydraulic cylinder 5 drives the slide plate 17 and the liquid accumulation kettle 10 to slide synchronously in the horizontal direction. When the liquid accumulation kettle 10 slides to the top of the second opening, the baffle 11 opens, and the liquid accumulation kettle 10 is connected with the discharge channel 13. The discharge channel 13 transports the liquid to the next process.

[0031] The embodiment of the present invention performs flocculation treatment on boiler water by providing a base 4, a mixing kettle 2 and a liquid accumulation kettle 10, which can improve the treatment efficiency of boiler water and extend the service life of the equipment. By providing a stirring mechanism 9, water with colloids and organic matter can be stirred and mixed with the coagulant discharged from the liquid storage tank 8, and colloids and organic polymers are formed after mixing. Then, the stationary water is pumped into the interior of the liquid accumulation kettle 10 through the connecting pipe 14, and the stationary colloids and organic polymers will form a pool of paste attached to the upper surface of the slide plate 17 waiting to be cleaned, thereby improving the purity of the liquid.

[0032] Furthermore, a liquid spraying pipe is fixedly installed at the lower end of the liquid storage tank 8 , and the liquid spraying pipe is located inside the mixing kettle 2 .

[0033] Furthermore, slide grooves are provided on both sides of the bottom of the mixing kettle 2, and the slide plate 17 is slidably and sealedly matched with the slide grooves.

[0034] Furthermore, the two sides of the liquid accumulation kettle 10 are respectively fixedly connected to the side plates 12, and the cylinder rod of the hydraulic cylinder 5 is fixedly connected to the side plates 12. The cylinder body of the hydraulic cylinder 5 is fixedly connected to the base 4 through the fixing block 3.

[0035] Furthermore, the hydraulic cylinder 5 is an electric hydraulic cylinder 5 .

[0036] In some embodiments, a sealing strip is connected to the slideway, and the slideway is slidably sealed to the mixing kettle 2, so as to ensure the sealing of the mixing kettle 2 before the slide plate 17 is removed.

[0037] In some embodiments, a door body 7 that can be opened and closed is provided on the side of the base 4 , and the receiving barrel 24 can be taken out and placed by opening the door body 7 .

[0038] In some embodiments, the foldable hose 15 is arranged in a vertical direction, and a feed port of the foldable hose 15 is located at a lower end of the foldable hose 15 , and the feed port of the foldable hose 15 is connected to a filtering device 16 to filter out the paste.

[0039] In some embodiments, a scraper 6 is provided at the bottom of the mixing kettle 2, and the lower end surface of the scraper 6 is in contact with the upper end surface of the slide plate 17. When the slide plate 17 slides in a direction away from the mixing kettle 2, the scraper 6 scrapes off the sediment on the slide plate 17 and drops it into the receiving barrel 24.

[0040] In some embodiments, the filter device 16 includes a floating plate and a filter screen. The floating plate is fixedly connected to the feed port of the folding hose 15. The floating plate is provided with a through hole in the vertical direction. The filter screen is detachably connected in the through hole. The floating plate is made of a foam board. Due to the light weight of the floating plate and the folding hose 15, the lower surface of the floating plate can be in contact with the water surface, so that clean liquid can be extracted all the time, and the floating plate can also float with the height of the water level.

[0041] In some embodiments, the bottom of the liquid accumulation kettle 10 is an inclined surface 18, and the inclined surface 18 is inclined downward toward the baffle 11. The liquid in the liquid accumulation kettle 10 is directed toward the discharge port to reduce the liquid residue in the liquid accumulation kettle 10.

[0042] In some embodiments, a plate groove 19 for accommodating the baffle 11 is horizontally opened at the discharge port of the liquid accumulation kettle 10, and the baffle 11 slides horizontally toward or away from the plate groove 19. A storage groove 20 is opened at the bottom of the liquid accumulation kettle 10, and a plurality of spring telescopic rods 22 are installed in the storage groove 20. One end of the spring telescopic rod 22 is fixedly connected to one side of the storage groove 20, and the other end of the spring telescopic rod 22 is connected to the baffle 11. The baffle 11 and the spring telescopic rod 22 are fixedly connected by a vertically arranged dial plate 23. The extension and retraction of the spring telescopic rod 22 drives the movement of the baffle 11, thereby controlling the opening and closing of the discharge port of the liquid accumulation kettle 10. Under normal conditions, the spring telescopic rod 22 is in an extended state, and the baffle 11 closes the discharge port of the liquid accumulation kettle 10.

[0043] A bottom groove 25 is provided at the upper end of the base 4, and one side of the bottom groove 25 is fixedly connected to the vertical plate 26. The bottom surface of the bottom groove 25 fits with the bottom surface of the paddle plate 23. When the slide plate 17 slides in the direction away from the mixing kettle 2, the paddle plate 23 abuts against the vertical plate 26 and squeezes, so that the paddle plate 23 squeezes the spring telescopic rod 22 to a fully contracted state, thereby opening the discharge port of the liquid accumulation kettle 10.

[0044] When the slide plate 17 slides toward the mixing kettle 2 , due to the elastic restoring force of the spring telescopic rod 22 , it can automatically extend to drive the baffle plate 11 to move, thereby closing the discharge port of the liquid accumulation kettle 10 .

[0045] In some embodiments, a row of rollers 21 are respectively provided on both sides of the bottom of the liquid accumulation kettle 10, and the liquid accumulation kettle 10 slides on the upper end of the base 4 through the rollers 21. By providing the rollers 21, the liquid accumulation kettle 10 can move on the base 4 more stably and smoothly.

[0046] In some embodiments, the discharge channel 13 is L-shaped.

[0047] During operation, when it is necessary to remove the colloid and organic matter in the liquid, the liquid is introduced into the mixing kettle 2 through the liquid inlet pipe 1 and is on the surface of the slide 17. Then, the coagulant in the liquid storage tank 8 is added to the liquid, and the stirring mechanism 9 is started to mix them fully. After the stirring is completed, the liquid is allowed to stand to allow the paste formed by the mixture of the colloid, organic matter and coagulant to gradually sink and gather on the slide 17. Then, by starting the small pump body, the foldable hose 15 located on the water level surface starts to pump water. Since the impurities such as the paste sink to the bottom of the liquid after standing, the water quality at the top of the liquid will be improved. At this time, the liquid is pumped into the liquid accumulation kettle 10 for temporary storage. As the liquid is pumped, the water level becomes lower and lower.

[0048] When all the required liquid is extracted, the hydraulic cylinder 5 is started to drive the slide plate 17 and the liquid accumulation kettle 10 to move synchronously in the direction away from the mixing kettle 2. At this time, the paste on the surface of the slide plate 17 will contact the scraper 6. As the slide plate 17 moves, most of the paste will flow directly into the receiving barrel 24 because it still contains water, and a small part of the paste will be scraped off by the scraper 6. As the liquid accumulation kettle 10 moves, the paddle plate 23 will contact the vertical plate 26, so that the paddle plate 23 drives the baffle plate 11 to enter the plate groove 19. At this time, the liquid inside the liquid accumulation kettle 10 will flow from the discharge port to the L-shaped discharge channel 13, and the discharge channel 13 will transport the liquid to the next filtration step.
