Description

Technical Field

[0001] This invention relates to the field of water-reducing agent production equipment technology, and in particular to an antifreeze polycarboxylate-based composite pumped water-reducing agent and its production equipment. Background Technology

[0002] Water-reducing agents are concrete admixtures that reduce the amount of water used in mixing while maintaining a relatively constant slump. When added to concrete mixes, they disperse cement particles, improve workability, reduce water consumption per unit area, improve the fluidity of the concrete mix, or reduce cement usage per unit area, thus saving cement.

[0003] Water-reducing agents are divided into powder and liquid forms. Liquid forms are added to concrete, while powder forms are for ease of transport and need to be mixed with water to the required proportions for normal use. Existing equipment first adds water to the mixing tank, then pours in the powder. The powder is initially added by the bag, which is prone to loss during bagging and transportation. Water is then poured directly into the mixing tank beforehand. Furthermore, the powder is easily spilled around the equipment when opened, and when added to the mixing tank, it is easily scattered due to the pouring process. This results in the powder entering the mixing tank not achieving the required mixing ratio. Since the amount of scattered and spilled powder cannot be calculated, it is easy to produce liquid-based agents that do not meet the required proportions. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an antifreeze polycarboxylate-based composite pumpable water-reducing agent and its production equipment.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a production equipment for an antifreeze polycarboxylate-based composite pumpable water-reducing agent, comprising a mixing and stirring device, which includes a mixing tank, stirring blades, and a vertical floating device.

A feeding hopper and a metering mixing device are provided on the mixing tank. Powder is poured into the feeding hopper, and a discharge port is provided below the feeding hopper. The metering mixing device includes a rotating disc, which is rotatably disposed on the mixing tank. A metering chamber is provided on the rotating disc, and a feeding port is provided on the side of the metering chamber. The outer wall of the feeding port abuts against the inner wall of the mixing tank. The rotating disc drives the metering chamber to rotate, and the discharge port aligns with the feeding port, thereby allowing the powder to enter the metering chamber. A sliding hole is provided on the upper surface of the quantitative chamber, and a spraying device is slidably mounted on the sliding hole. The spraying device is equipped with multiple spray heads. A material discharge hole is provided on the rotating disk. The spray head can block the material discharge hole by sliding downward and open it by sliding upward. An adsorption ring is rotatably mounted on the stirring blades. A guide device is also provided on the stirring tank. The adsorption ring is slidably mounted on the guide device. The rotation of the stirring blades can drive the adsorption ring to slide up and down. An electromagnetic adsorption block is provided on the adsorption ring.

When the electromagnetic adsorption block is energized, it can magnetically pull the telescopic head into the water outlet, thereby supplying water to the spray head.

[0006] Its beneficial effects are that it can automatically extract the poured powder in a quantitative manner and mix it with water in a quantitative manner.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: See also Figures 1-6 ,

[0023] An antifreeze polycarboxylate-based composite pumpable water-reducing agent, by weight percentage, comprises 8% polycarboxylate high-efficiency water-reducing agent, 1% sodium gluconate, 0.08% sodium dodecyl sulfate, 1.5% triethanolamine, 10% sodium thiosulfate, 12% methanol, and the balance being water.

[0024] A production device for an antifreeze polycarboxylate-based composite pumpable water-reducing agent includes a mixing and stirring device 1. The mixing and stirring device 1 includes a mixing tank 11, stirring blades 12, a floating device 13, an adsorption ring 14, a servo motor 15, and a power motor 16. The power motor 16 is located at the upper end of the mixing tank 11, and a hexagonal shaft is mounted on the motor shaft of the power motor 16. The stirring blades 12 rotate and are slidably positioned within the mixing tank 11 with upper and lower limits. The upper end of the stirring blades 12 has a hexagonal shaft hole that mates with the hexagonal shaft. The hexagonal shaft of the power motor 16 is slidably positioned within the hexagonal shaft hole, thereby facilitating mixing. The blade 12 can also transmit power when sliding up and down. The lower end of the stirring blade 12 is provided with an annular track 121, which has high and low points and is a continuous track. The floating device 13 is a guide ball 131, which is configured to cooperate with the annular track 121. The guide ball 131 is fixedly set at the bottom of the stirring tank 11. Therefore, when the stirring blade 12 rotates, the stirring blade 12 moves along the annular track 121, thereby realizing up and down movement at the same time as rotation. The stirring blade 12 moves up and down once for every one rotation.

[0025] A servo motor 15 is mounted on the mixing tank 11. A rotating shaft 151 is mounted on the servo motor 15. An adsorption ring 14 is guided and slidably mounted on the rotating shaft 151. At the same time, the stirring blade 12 is limited in the upper and lower positions and rotated on the adsorption ring 14. Thus, when the stirring blade 12 rotates and slides up and down, it drives the adsorption ring 14 to move up and down together. A second gear 152 is mounted at the front end of the rotating shaft 151.

[0026] The mixing tank 11 is also equipped with a feeding hopper 2, a drying device 3, and a quantitative mixing device 4. The mixing device 4 includes a rotating disk 41, a quantitative chamber 42, and a spraying device 43. The rotating disk 41 is rotatably mounted on the mixing tank 11, and a first gear 412 is provided on the rotating disk 41. A second gear 152 meshes with the first gear 412, thereby causing the servo motor 15 to rotate and drive the rotating disk 41 to rotate on the mixing tank 11. Three quantitative chambers 42 are evenly arranged on the rotating disk 41. Each quantitative chamber 42 has a feeding port 421 at its upper outer side, and the outer wall of the feeding port 421 touches the inner wall of the mixing tank 11. This causes the feed inlet 421 to be blocked, while the two adjacent metering chambers 42 are connected to each other to form a complete ring. The feed hopper 2 is located on the upper side of the mixing tank 11. The bottom of the feed hopper 2 has a discharge port 21, which is at the same height as the feed inlet 421. At the same time, the width of the discharge port 21 is smaller than the width of the feed inlet 421. When the discharge port 21 is aligned with the feed inlet 421, the discharge port 21 is connected to the feed inlet 421. The feed hopper 2 contains water-reducing agent powder, and a flip-up cover is provided at the upper end of the feed hopper 2 to close the upper opening of the feed hopper 2 when no material is being discharged.

[0027] The feed hopper 2 is equipped with a vibration device 22, which includes a sliding block 221, a rotating plate 222 and an impact plate 223. The impact plate 223 is disposed on the feed hopper 2, and multiple sliding blocks 221 are elastically slidably disposed on the impact plate 223. The rotating plate 222 is disposed on the rotating shaft of the power motor 16, and multiple top contact blocks 2221 are disposed on the rotating plate 222.

[0028] When the rotating plate 222 rotates, the top contact block 2221 can contact the sliding block 221, causing it to slide outward. After the top contact block 2221 passes, it elastically resets and impacts the impact plate 223, causing the feed hopper 2 to vibrate. When the discharge port 21 is aligned with the feed port 421, it can automatically knock the feed hopper 2, causing the powder to quickly enter the metering chamber 42 and fill the metering chamber 42 with powder.

[0029] The mixing tank 11 is divided into three functional areas: feeding area A, mixing area B, and drying area C. Feeding area A is the location of the feeding hopper 2, which fills the quantitative chamber 42 at each inlet 21 with a quantitative amount of powder.

[0030] The quantitative chamber 42 has multiple sliding holes 422 on its upper surface, the rotating disk 41 has multiple material dropping holes 411, and the spraying device 43 is equipped with multiple spray heads 433. The spray heads 433 are guided and slidably disposed in the sliding holes 422 and the material dropping holes 411, and the bottom end of the spray head 433 is provided with spray holes in the circumferential direction. When there is water flow in the spray head 433, it can spray in a scattered manner to all directions.

[0031] In the initial state, the spraying device 43 presses against the metering chamber 42, and the spraying head 433 is located inside the sliding hole 422 and the discharge hole 411, thereby blocking the sliding hole 422 and the discharge hole 411. When the spraying device 43 moves upward, the lower end of the spraying head 433 leaves the discharge hole 411, thereby opening the discharge hole 411 and allowing material to be discharged downward.

[0032] An electromagnetic adsorption block 141 is provided on the adsorption ring 14. The area where the electromagnetic adsorption block 141 is located on the adsorption ring 14 is the mixing area B. A first magnetic block 431 is provided on the spraying device 43. When the electromagnetic adsorption block 141 is energized, it can attract the first magnetic block 431, causing the spraying device 43 to slide up and down together. A telescopic head 432 is also elastically slidably provided inside the first magnetic block 431. A water outlet hole 142 is opened on the electromagnetic adsorption block 141. When the electromagnetic adsorption block 141 is energized, it can magnetically draw the telescopic head 432 into the water outlet hole 142, thereby supplying water to the spraying head 433.

[0033] In the initial state, the bagged powder is opened and poured into the feed hopper 2. At this time, the three metering chambers 42 are located in three different areas, and the spraying device 43 in the feeding area A is always in contact with the metering chamber 42, so that the metering chamber 42 has only one external opening, the feed inlet 421. At this time, the equipment is started, the power motor 16 starts to rotate, thereby driving the rotating plate 222 to rotate, causing the feed hopper 2 to vibrate. The powder enters the metering chamber 42 through the feed inlet 421. Since the height of the feed hopper 2 is higher than that of the metering chamber 42, the powder can automatically fill the metering chamber 42 when the feed hopper 2 vibrates. Since the three metering chambers 42 are the same, the amount of powder filled each time is the same.

[0034] After the equipment has been running for a certain period of time, once the quantitative chamber 42 is full, the servo motor 15 starts to rotate, rotating the full quantitative chamber 42 to the mixing area B and stopping rotation. The quantitative chamber 42, which was previously located in the drying area C, enters the feeding area A. While the servo motor 15 is rotating, the power motor 16 is always rotating. Therefore, after the new quantitative chamber 42 enters below the feeding hopper 2, the feeding hopper 2 continues to load materials.

[0035] After the quantitative chamber 42 is in position and stops rotating, the servo motor 15 also stops rotating. Simultaneously, the servo motor 15 controls the electromagnetic adsorption block 141 to be energized. Since the mixing area B is equipped with a sliding adsorption ring 14, when the electromagnetic adsorption block 14 moves to its lowest point, it attracts the first magnetic block 431. At the same time, the telescopic head 432 is drawn into the water outlet 142, pressing against the pressure switch inside the water outlet 142, thereby controlling the water outlet 142 to discharge water. The amount of water sprayed from the water outlet 142 is determined by the equipment's... The central controller controls the water to be dispensed in a set ratio with the powder in the metering chamber 42. Water from the outlet 142 enters the spray head 433 through the telescopic head 432 and is sprayed out from the spray hole at the bottom of the spray head 433. At this time, the adsorption ring 14 slides up and down continuously, thereby driving the spray head 433 to slide up and down, so that the bottom of the spray head 433 enters the metering chamber 42, causing the water to be sprayed onto the powder in the metering chamber 42, thereby dissolving the powder. The dissolved mixed water flows down from the discharge hole 411 into the mixing tank 11.

[0036] The adsorption ring 14 slides up and down continuously, thereby causing the spray head 433 to slide up and down continuously to spray water, so that the powder in the metering chamber 42 is fully dissolved. After the metered water is sprayed, the electromagnetic adsorption block 141 is de-energized, so the adsorption between the electromagnetic adsorption block 141 and the first magnetic block 431 disappears, and the telescopic head 432 also elastically resets and retracts into the first magnetic block 431. The spraying device 43 presses against the metering chamber 42 again. During this process, the stirring blade 12 is always rotating, thereby stirring the flowing solution.

[0037] After the equipment has been running for a set time, the servo motor 15 starts to rotate, and rotates the filled metering chamber 42 back to the mixing zone B and stops rotating. The empty metering chamber 42 that was previously in the mixing zone B enters the drying zone C. The metering chamber 42 in the drying zone C then enters the feeding zone A. The set time is adjusted according to the ratio of the mixed water agent and is longer than the spraying time of the spray head 433.

[0038] The drying device 3 is located in the drying area C. The drying device 3 includes a blower 31, an air inlet pipe and an air outlet pipe 32. The air inlet pipe and the air outlet pipe 32 are located on the side of the mixing tank 11 and at the same height as the feed inlet 421. They stop after the quantitative chamber 42 enters the drying area C. At this time, the air inlet pipe and the air outlet pipe 32 are located at the left and right ends of the feed inlet 421, respectively. The blower 31 is located on the side of the mixing tank 11 and is connected to the air inlet pipe.

[0039] When entering the drying zone C, the spray device 43 presses against the metering chamber 42 again, thus the material discharge hole 411 is blocked again. Therefore, the blower 31 starts to work, blowing outside air into the metering chamber 42 and then discharging it outward from the air outlet duct 32, thereby drying the inside of the metering chamber 42.

[0040] Its working principle or usage method is as follows:

[0041] In the initial state, the bagged powder is opened and poured into the feed hopper 2. At this time, the three metering chambers 42 are located in the three areas respectively, and the spraying device 43 in the feeding area A is always in contact with the metering chamber 42, so that the metering chamber 42 has only one external opening, the feed port 421. At this time, the equipment is started, the power motor 16 starts to rotate, thereby driving the rotating plate 222 to rotate, causing the feed hopper 2 to vibrate. The powder enters the metering chamber 42 through the feed port 421. Since the height of the feed hopper 2 is higher than that of the metering chamber 42, the powder can automatically fill the metering chamber 42 when the feed hopper 2 vibrates. Since the three metering chambers 42 are the same, the amount of powder filled each time is the same.

[0042] After the equipment has been running for a certain period of time, once the quantitative chamber 42 is full, the servo motor 15 starts to rotate, rotating the full quantitative chamber 42 to the mixing area B and stopping rotation. The quantitative chamber 42, which was previously located in the drying area C, enters the feeding area A. While the servo motor 15 is rotating, the power motor 16 is always rotating. Therefore, after the new quantitative chamber 42 enters below the feeding hopper 2, the feeding hopper 2 continues to load materials.

[0043] After the quantitative chamber 42 is in position and stops rotating, the servo motor 15 also stops rotating. Simultaneously, the servo motor 15 controls the electromagnetic adsorption block 141 to be energized. Since the mixing area B is equipped with a sliding adsorption ring 14, when the electromagnetic adsorption block 14 moves to its lowest point, it attracts the first magnetic block 431. At the same time, the telescopic head 432 is drawn into the water outlet 142, pressing against the pressure switch inside the water outlet 142, thereby controlling the water outlet 142 to discharge water. The amount of water sprayed from the water outlet 142 is determined by the equipment's... The central controller controls the water to be dispensed in a set ratio with the powder in the metering chamber 42. Water from the outlet 142 enters the spray head 433 through the telescopic head 432 and is sprayed out from the spray hole at the bottom of the spray head 433. At this time, the adsorption ring 14 slides up and down continuously, thereby driving the spray head 433 to slide up and down, so that the bottom of the spray head 433 enters the metering chamber 42, causing the water to be sprayed onto the powder in the metering chamber 42, thereby dissolving the powder. The dissolved mixed water flows down from the discharge hole 411 into the mixing tank 11.

[0044] The adsorption ring 14 slides up and down continuously, thereby causing the spray head 433 to slide up and down continuously to spray water, so that the powder in the metering chamber 42 is fully dissolved. After the metered water is sprayed, the electromagnetic adsorption block 141 is de-energized, so the adsorption between the electromagnetic adsorption block 141 and the first magnetic block 431 disappears, and the telescopic head 432 also elastically resets and retracts into the first magnetic block 431. The spraying device 43 presses against the metering chamber 42 again. During this process, the stirring blade 12 is always rotating, thereby stirring the flowing solution.

[0045] After the equipment has been running for a set time, the servo motor 15 starts to rotate, and rotates the filled metering chamber 42 back to the mixing zone B and stops rotating. The empty metering chamber 42 that was previously in the mixing zone B enters the drying zone C. The metering chamber 42 in the drying zone C then enters the feeding zone A. The set time is adjusted according to the ratio of the mixed water agent and is longer than the spraying time of the spray head 433.

[0046] Upon entering the drying zone C, the spray device 43 presses against the metering chamber 42 again, thus sealing the discharge hole 411. As a result, the blower 31 starts working, blowing outside air into the metering chamber 42 and then expelling it outward from the air outlet duct 32, thereby drying the inside of the metering chamber 42.

[0047] A discharge port is provided at the lower end of the mixing tank 11, and an electric valve is installed on the discharge port. When the servo motor 15 starts to rotate, that is, when the spray head 433 is not spraying water, the electric valve can be controlled to open and automatically output the mixed water-reducing agent solution. After the servo motor 15 stops rotating, the electric valve automatically closes, thereby ensuring that the output water-reducing agent solution meets the standard concentration.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
