Description

Technical Field

[0001] The utility model relates to the technical field of separation equipment, in particular to a separation device for concrete water reducing agent. Background Art

[0002] Concrete is one of the primary civil engineering materials of today. It is a man-made material made by mixing a binder, an aggregate water-reducing agent, and water in specific proportions, tamping and shaping it, and curing it under certain conditions. Its abundant raw materials, low cost, and simple production process have led to its increasing use. Concrete water-reducing agents are concrete admixtures that reduce mixing water consumption while maintaining a relatively constant slump. Most of these are anionic surfactants, including lignin sulfonates and naphthalene sulfonate formaldehyde polymers. When added to the concrete mix, they disperse cement particles, improving workability, reducing water consumption per unit area, and improving the flowability of the concrete mix; or, alternatively, reducing cement usage per unit area, thereby conserving cement.

[0003] The production of concrete water reducer generally includes five steps: sulfonation, hydrolysis, condensation, neutralization, and solid-liquid separation. Quicklime can be used instead of sodium hydroxide for neutralization during production. The high water reducer produced by quicklime neutralization will produce a large amount of calcium sulfate precipitate. After the calcium sulfate is precipitated and separated, a viscous water reducer will adhere to its surface. The existing technology lacks the treatment of calcium sulfate precipitate, making it impossible to dry the calcium sulfate precipitate and separate the water reducer for secondary use. A solution to the above problems is proposed below. Utility Model Content

[0021] See Figures 1 to 6 As shown, a separation device for concrete water reducer includes a base 1, a water tank 2, a separation outer barrel 3 and a separation inner barrel 4. The separation outer barrel 3 and the water tank 2 are both installed on the top of the base 1. The separation inner barrel 4 is slidably arranged in the separation outer barrel 3. An extension ring 5 is installed on the top of the separation outer barrel 3. The top of the separation inner barrel 4 cooperates with the extension ring 5. The separation inner barrel 4 is supported by the extension ring 5. Calcium sulfate used to separate the water reducer can be poured into the separation inner barrel 4 in advance, or after the separation inner barrel 4 is installed on the separation outer barrel 3, the calcium sulfate can be poured into the separation inner barrel 4. The water reducer is separated from the calcium sulfate through subsequent steps.

[0022] A support plate 7 is slidingly provided on the top of the separation outer barrel 3, and a driving component 8 for driving the support plate 7 to slide is also provided on the base 1. A driving motor 2 is installed on the top of the support plate 7. The output shaft of the driving motor 2 passes through the support plate 7 and is fixed with a connecting shaft 1 9. A stirring part 10 is installed at the bottom of the connecting shaft 1 9. When calcium sulfate needs to be processed, the stirring part 10 must be first inserted into the separation inner barrel 4, and the driving component 8 is used to drive the support plate 7 to rise and fall. During the lifting process of the support plate 7, the driving motor 2 will be started, and the connecting shaft will be driven to rotate by the output shaft of the driving motor 2. The connecting shaft will drive the stirring part 10 to rotate, thereby facilitating the stirring part 10 to penetrate into the interior of the separation inner barrel 4.

[0023] The driving assembly 8 includes a supporting plate 14, a driving plate 25, a screw 15, a connecting shaft 2 16 and a driving motor 17. The supporting plate 14 is fixed to the top of the base 1, and the driving plate 25 is fixed to the top of the supporting plate 14. A slide groove 18 is provided on the side wall of the driving plate 25. The screw 15 and the connecting shaft 2 16 are both installed in the slide groove 18. The driving motor 17 is fixed to the top of the driving plate 25. The output shaft of the driving motor 17 passes through the driving plate 25 and is fixedly connected to the screw 15. The screw 15 is rotated by the driving motor 17. One end of the support plate 7 is arranged in the slide groove 18 and cooperates with the screw 15 and the connecting shaft 2 16. The support plate 7 is slidably set on the screw 15 and the connecting shaft 1 9. The support plate 7 and the screw 15 are threadedly matched. When it is necessary to drive the support plate 7 to move, the drive motor 17 can be started first, and the screw 15 is driven to rotate by the output shaft of the drive motor 17. During the rotation process, the screw 15 will drive the support plate 7 that is threadedly matched with it to slide in the slide groove 18. By installing the connecting shaft 2 16, the support plate 7 is provided with a limited support.

[0024] A hollow water pan 11 is installed on the stirring part 10. The upper and lower ends of the hollow water pan 11 are connected to the stirring part 10 by waterproof bearings. The interior of the stirring part 10 is also a hollow structure. A water supply component 12 is provided on the water tank 2 for supplying water to the hollow water pan 11 and the stirring part 10. When the stirring part 10 enters the separation inner barrel 4, the water supply component 12 can be started. The hollow water pan 11 and the stirring part 10 are supplied with water through the water supply component 12, so that the calcium sulfate can be sprayed, rinsed and stirred, so that the water reducer attached to the calcium sulfate can be sprayed down. A number of drainage holes 6 are provided on the side wall and bottom of the separation inner barrel 4. The sprayed water reducer and water will be discharged into the separation outer barrel 3 through the drainage holes 6 on the separation inner barrel 4. A drainage pipe 24 connected to the interior of the separation outer barrel 3 is installed on the bottom side wall. The liquid can be discharged through the drainage pipe 24, which is convenient for subsequent processing.

[0025] The water supply assembly 12 includes a water pump 19, one end of which passes through the water tank 2 through a pipe and is arranged at the bottom of the water tank 2. A drain pipe 20 is installed at the other end of the water pump 19. The end of the drain pipe 20 away from the water pump 19 is connected to the hollow water tray 11. A water inlet is opened on the side wall of the stirring part 10, and the water inlet is located inside the hollow water tray 11. A plurality of sprinkler heads communicating with the inside of the hollow water tray 11 are installed at the bottom of the hollow water tray 11. When supplying water, the water pump 19 can be started, and the water pump 19 pumps water out of the water tank 2 through the pipe. , water can be supplied to the drain pipe 20 through the water pump 19, and the drain pipe 20 will discharge the water into the hollow water tray 11, and spray it out through the spray head at the bottom of the hollow water tray 11. The spray head corresponds to the separation inner barrel 4, and the calcium sulfate is flushed through the spray head. A water inlet is provided on the side wall of the stirring part 10, and the water inlet is located inside the hollow water tray 11. The spray water entering the hollow water tray 11 will also enter the stirring part 10 through the water inlet, so that the stirring part 10 can also flush the calcium sulfate while stirring it to improve the separation efficiency.

[0026] The drain pipe 20 is a flexible and retractable pipe, specifically a corrugated pipe. By designing the drain pipe 20 as a flexible and retractable pipe, the drain pipe 20 is prevented from being limited when the hollow water tray 11 is moved by the support plate 7.

[0027] The stirring portion 10 includes a stirring shaft 21 and a plurality of stirring blades 22. The stirring shaft 21 is fixed to the bottom of the connecting shaft 9, and the stirring blades 22 are fixed to the side walls of the stirring shaft 21. The stirring blades 22 are staggered, and the water inlet is opened on the stirring shaft 21. The stirring shaft 21 and the stirring blades 22 both adopt a hollow structure. The stirring shaft 21 and the stirring blades 22 are internally communicated. A plurality of drainage ports are opened on the stirring blades 22. The spray water will enter the stirring blades 22 through the stirring shaft 21 and be discharged through the drainage port opened at the bottom of the stirring blades 22, so that the calcium sulfate can be flushed.

[0028] The stirring part 10 is also provided with a lifting part 13 for lifting the separation inner barrel 4. The lifting part 13 is a cross lifting plate. The cross lifting plate is fixed to the top side wall of the stirring part 10. A lifting ring 23 is fixed to the top of the inner wall of the separation inner barrel 4. The lifting ring 23 is provided with a wide groove corresponding to the cross lifting plate. When the stirring part 10 rotates to penetrate into the separation inner barrel 4, when the lifting part 13 is about to contact the lifting ring 23, the stirring part 10 will stop rotating, and the lifting part 13 will correspond to the wide groove, so that the lifting part 13 can penetrate into the separation inner barrel 4. The length of the stirring blade 22 of the stirring part 10 is less than the lifting ring 23. The inner side of the lifting ring 23 is straight, and the stirring blade 22 will not come into contact with the lifting ring 23. When the lifting part 13 penetrates into the separation inner barrel 4, the drive motor 2 can be restarted to realize the rotation of the stirring part 10 again. When the separation inner barrel 4 needs to be taken out from the separation outer barrel 3 after flushing, the driving component 8 can be started. By lifting the driving component 8, the separation inner barrel 4 can be lifted up by the lifting part. The separation inner barrel 4 can be suspended on the top of the separation outer barrel 3 first, so that the water in the separation inner barrel 4 can be drained, reducing the waste of the water reducer and preventing the liquid from dripping everywhere after taking the separation inner barrel 4.
