Description

Technical Field

[0001] This application relates to the technical field of water reducer production, and particularly to a water reducer compounding tank. Background Art

[0002] Water reducers are prepared using a compounding tank. The water reducer mother liquor, admixture powder, and solvent are put into the compounding tank according to a certain ratio for mixing. After being mixed evenly, they are discharged to complete the preparation of the water reducer.

[0003] Currently, when preparing water reducers, the mother liquor and powder are usually directly added into the compounding tank through a hopper, then the solvent is added, and they are stirred evenly by a stirring structure. The scraping strip that abuts against the side wall of the compounding tank scrapes off the mother liquor and powder adhering to the side wall of the compounding tank to complete the preparation of the water reducer.

[0004] In the above solution, the mother liquor and powder are likely to adhere to the inner wall of the tank body. Although there is a scraping strip for scraping, some of the mother liquor and powder still remain on the inner wall of the tank body, which is likely to affect the concentration of the water reducer. Utility Model Content

[0005] In order to reduce the residue of the mother liquor and powder in the compounding tank and make the preparation concentration of the water reducer not easily affected, this application provides a water reducer compounding tank.

[0006] The water reducer compounding tank provided by this application adopts the following technical solution:

[0007] A water reducer compounding tank includes a tank body and a feeding pipe. The feeding pipe penetrates through the top end of the tank body. The part of the side wall of the feeding pipe located inside the tank body is provided with a plurality of liquid outlet holes along the circumferential and axial directions. The top end of the feeding pipe is open, and the bottom end is sealed.

[0008] By adopting the above technical solution, during feeding, the mother liquor and powder are first put into the feeding pipe from the top end of the feeding pipe. The mother liquor and powder spill inside the feeding pipe, and then the solvent is put into the feeding pipe. The solvent flushes the mother liquor and powder inside the feeding pipe and carries the mother liquor and powder to flow into the tank body through the liquid outlet holes.

[0009] The feeding pipe confines the mother liquor and powder within itself, making it difficult for the mother liquor and powder to diffuse during feeding. The solvent can continuously flush the mother liquor and powder when it is put in, and the solvent mixes with the mother liquor and powder during the flushing process. On the one hand, it makes it difficult for the mother liquor and powder to adhere to the inside of the feeding pipe. On the other hand, it makes the mother liquor and powder enter the tank body in a mixed state, making it difficult for the mother liquor and powder to adhere to the inner wall of the tank body. Therefore, by feeding the mother liquor and powder through the feeding pipe, the residue of the mother liquor and powder in the compounding tank is reduced, and the preparation concentration of the water reducer is not easily affected.

[0010] Optionally, one end of the feeding pipe located outside the tank body is communicated with a funnel.

[0011] By adopting the above technical solution, the mother liquor and powder are put into the feeding pipe through the funnel, so that the mother liquor and powder are not easily spilled outside the feeding pipe, reducing the difficulty of feeding the feeding pipe.

[0012] Optionally, the bottom end of the side wall of the tank body is communicated with a return pipe, the other end of the return pipe is communicated with the side wall of the funnel, and a water pump is arranged on the return pipe near the tank body.

[0013] By adopting the above technical solution, the water pump can extract the mixed solution in the tank body and flow it into the return pipe, and make the mixed solution flow back to the funnel, so that the mixed solution can circulate between the feeding pipe and the return pipe, and the mother liquor and powder in the feeding pipe can be continuously washed, further making the mother liquor and powder not easily remain in the feeding pipe.

[0014] Optionally, a closing cover is threadedly connected to the open end of the funnel.

[0015] By adopting the above technical solution, after the solvent is put in, the funnel can be closed by the closing cover. On the one hand, the closing cover can prevent foreign objects from falling into the feeding pipe from the funnel. On the other hand, after the closing cover closes the funnel, the water pump can make the mixed solution pressurize and flow back into the feeding pipe, and the pressurized return mixed solution enhances the washing of the inner side wall of the feeding pipe, making the mother liquor and powder less likely to remain in the feeding pipe.

[0016] Optionally, a motor is fixedly connected to the bottom end of the tank body, the output shaft of the motor rotates through the tank body, and is coaxially fixedly connected to the feeding pipe. The feeding pipe is rotatably connected to the tank body and rotatably connected to the funnel.

[0017] By adopting the above technical solution, under the pressurizing action of the water pump, the mixed solution in the feeding pipe can be sprayed from the liquid outlet hole to the inner side wall of the tank body to form a water jet. The motor can drive the feeding pipe to rotate, and the feeding pipe can drive the water jet to rotate when rotating. On the one hand, the water jet can wash the inner side wall of the tank body, so that the mother liquor and powder are not easily adhered to the inner side wall of the tank body during the mixing process. On the other hand, the water jet can stir the mixed solution to promote the uniform mixing of the mother liquor, powder and solvent.

[0018] Optionally, a scraping rod is fixedly connected to the bottom end of the feeding pipe, and the scraping rod is arranged in contact with the bottom end and the side wall of the tank body.

[0019] By adopting the above technical solution, the scraping rod can be driven to rotate synchronously when the feeding pipe rotates, and the scraping rod can scrape off the mother liquor and powder adhered to the inner side wall and the bottom end of the tank body, making the mother liquor and powder less likely to adhere to the inner wall of the tank body.

[0020] Optionally, both sides of the scraping rod are inclined towards each other in a direction close to the interior of the tank body.

[0021] By adopting the above technical solution, the scraping rod scrapes the inner side wall and the bottom end of the tank body through the inclined side surface, improving the scraping effect of the scraping rod.

[0022] Optionally, the part of the scraping rod that fits the side wall of the tank body is disposed opposite to one of the liquid outlet holes in the circumferential direction of the feeding pipe.

[0023] By adopting the above technical solution, the water jet ejected from the liquid outlet hole can impact on the scraping rod, and the water jet flushes the scraping rod, so that the mother liquor and powder scraped by the scraping rod are not easily retained on the scraping rod, thereby further reducing the residue of the mother liquor and powder in the compounding tank.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. By providing the tank body, the feeding pipe and opening the liquid outlet holes on the feeding pipe, the residue of the mother liquor and powder in the compounding tank is reduced, and the preparation concentration of the water reducing agent is not easily affected;

[0026] 2. By providing the reflux pipe, the water pump and the closing cover, the mixed solution can be pressurized and refluxed in the feeding pipe, making it difficult for the mother liquor and powder to remain in the feeding pipe;

[0027] 3. By providing the motor, the feeding pipe can rotate, so that the water jet ejected from the liquid outlet hole can stir the mixed solution and can wash the inner side wall of the tank body. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will further describe the present application in detail with reference to the Figure 1-2 accompanying drawings.

[0033] An embodiment of the present application discloses a water reducing agent compounding tank. Referring to Figure 1 , a water reducing agent compounding tank includes a tank body 1, a feeding pipe 2 and a reflux pipe 3.

[0034] Referring toFigure 2 , the tank body 1 is in the shape of a circular box and is vertically arranged. The feeding pipe 2 is in the shape of a circular tube and is coaxially penetrated through the top end of the tank body 1. The feeding pipe 2 is rotatably connected to the tank body 1. The top end of the feeding pipe 2 is open, and the bottom end is sealed. The bottom end of the feeding pipe 2 abuts against the bottom end of the tank body 1.

[0035] A plurality of liquid outlet holes 21 are uniformly arranged on the part of the side wall of the feeding pipe 2 located inside the tank body 1 along the circumferential and axial directions. The liquid outlet holes 21 are rectangular, and the length direction is parallel to the axis direction of the feeding pipe 2. The liquid outlet holes 21 penetrate through the wall thickness of the feeding pipe 2.

[0036] The top end of the feeding pipe 2 is communicated with a conical funnel 22 and is rotatably connected to the funnel 22.

[0037] The reflux pipe 3 is located outside the tank body 1, and one end is communicated with the bottom end of the side wall of the tank body 1. The other end of the reflux pipe 3 is communicated with the side wall of the funnel 22. A water pump 31 is arranged on the end of the reflux pipe 3 close to the tank body 1. The water pump 31 is used to extract the mixed solution in the tank body 1.

[0038] The open end of the funnel 22 is threadedly connected with a sealing cover 23, and the sealing cover 23 is adapted to the open end of the funnel 22.

[0039] During use, the mother liquor and the powder are first added into the feeding pipe 2 from the funnel 22, then the solvent is added into the feeding pipe 2 from the funnel 22, and then the sealing cover 23 is screwed onto the funnel 22 to seal the funnel 22. The solvent flushes the mother liquor and the powder in the feeding pipe 2. After the solvent is mixed with the mother liquor and the powder, it flows into the tank body 1 from the liquid outlet holes 21. The water pump 31 is started. The water pump 31 extracts the mixed solution in the tank body 1 and pressurizes it to flow into the reflux pipe 3. The mixed solution is pressurized and refluxed into the feeding pipe 2 from the funnel 22, and pressurizes and flushes the mother liquor and the powder in the feeding pipe 2, reducing the residue of the mother liquor and the powder in the feeding pipe 2 and making the preparation concentration of the water reducing agent not easily affected.

[0040] Refer to Figure 2 , a motor 4 is fixedly connected to the bottom end of the tank body 1. The output shaft of the motor 4 rotatably penetrates into the tank body 1 and is fixedly connected to the feeding pipe 2. The output shaft of the motor 4 is coaxially arranged with the feeding pipe 2.

[0041] A scraping rod 5 is fixedly connected to the bottom end of the feeding pipe 2.

[0042] Both sides in the extending direction of the scraping rod 5 are inclined towards each other in the direction close to the inside of the tank body 1.

[0043] The part of the scraping rod 5 in contact with the side wall of the tank body 1 is arranged opposite to one of the circumferential liquid outlet holes 21 of the feeding pipe 2.

[0044] During use, the mixed solution is sprayed from the liquid outlet hole 21 onto the inner wall of the tank body 1 and forms a water jet. The motor 4 is started, and the motor 4 drives the feeding pipe 2 to rotate. The feeding pipe 2 drives the water jet and the scraping rod 5 to rotate. The water jet agitates the mixed solution to promote the mixing of the mother liquor, the powder material, and the solvent. Moreover, the water jet flushes the mother liquor and the powder material adhering to the inner wall of the tank body 1. The scraping rod 5 scrapes the mother liquor and the powder material adhering to the inner wall and the bottom end of the tank body 1, reducing the residue of the mother liquor and the powder material in the tank body 1 and making it less likely that the preparation concentration of the water reducing agent is affected.

[0045] The implementation principle of a water reducing agent compounding tank according to an embodiment of the present application is as follows: During use, the mother liquor, the powder material, and the solvent are sequentially added into the feeding pipe 2. Then, the closing cover 23 is screwed onto the funnel 22. The water pump 31 and the motor 4 are started. The water pump 31 pumps the mixed solution in the tank body 1, pressurizes it, and returns it to the feeding pipe 2. The mixed solution pressurizes and flushes the mother liquor and the powder material in the feeding pipe 2. The mixed solution is sprayed out from the liquid outlet hole 21 and forms a water jet. The motor 4 drives the feeding pipe 2 to rotate. The feeding pipe 2 drives the water jet and the scraping rod 5 to rotate. The water jet agitates the mixed solution and flushes the inner wall of the tank body 1. The scraping rod 5 scrapes the inner wall and the bottom end of the tank body 1, thereby reducing the residue of the mother liquor and the powder material in the tank body 1 and making it less likely that the preparation concentration of the water reducing agent is affected.
