Description

Technical Field

[0001] The utility model relates to the technical field of water reducing agents, in particular to a high-speed disperser for water reducing agents. Background Art

[0002] Water reducers are divided into aqueous solutions and powders according to their appearance. The solid content of aqueous solutions is generally 20%, 40% (also known as mother liquor), and 60%, while the solid content of powders is generally 98%. When producing water reducers, monomers need to be added into water and stirred, and then AB materials are prepared. Then, subsequent additives such as catalysts are added to the original liquid and stirred and mixed. After a certain reaction time, the mother liquor is formed. Monomers usually refer to polyether macromonomers used in the synthesis of polycarboxylic acid water reducers.

[0003] Generally, a disperser is used in the production of water reducers. Monomers and water are added to a container, and the container is placed under the agitator shaft of the disperser. The disperser is then started to drive the agitator shaft and the serrated circular impeller installed on the agitator shaft to rotate, thereby stirring the liquid in the container. Catalysts are then added or AB materials are added dropwise for stirring. Generally, a disperser is equipped with a hydraulic lifting device to adjust the height of the agitator shaft. When adding materials, the newly added liquid is usually added directly from the opening of the container, causing the newly added liquid to fall directly on top of the original liquid in the container. If there are differences in physical properties such as density between the liquids, it will take a long time to stir the two liquids evenly, resulting in low mixing efficiency and inconvenience.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 In an embodiment of the present invention, a high-speed water reducer disperser comprises:

[0024] The machine body 100, the stirring shaft 200 for driving the impeller to rotate, the introduction mechanism 300 for injecting additives into the stirring shaft 200, and the ejection mechanism 400 for ejecting additives. The top end of the stirring shaft 200 is rotatably connected to the machine body 100. The stirring shaft 200 is a hollow structure. The introduction mechanism 300 is located in the middle of the stirring shaft 200. The introduction mechanism 300 includes a circular shell 310, and the inner wall of the circular shell 310 is rotatably connected to the outer wall of the stirring shaft 200. A plurality of water inlet holes 201 are provided on the outer wall of the stirring shaft 200, and the plurality of water inlet holes 201 are all located inside the circular shell 310. A conduit 320 is fixedly connected to the outer wall of the circular shell 310, and the interior of the conduit 320 is connected to the interior of the circular shell 310. An electromagnetic valve 330 is fixedly connected to one end of the conduit 320. Two ejection outlets 202 are provided at the bottom end of the outer wall of the stirring shaft 200. The ejection mechanism 400 is located inside the stirring shaft 200.

[0025] Specifically, a container is placed under the stirring shaft 200, and materials are added inside. By placing liquid additives into a water tank and connecting the water tank to the solenoid valve 330 through a pipe, the additives can enter the conduit 320 through the pipe, and flow from the conduit 320 through the circular shell 310 and multiple water inlet holes 201 into the stirring shaft 200. There is an impeller at the bottom of the stirring shaft 200. When in use, the impeller is located inside the container to stir the water flow for stirring. The height of the stirring shaft 200 can be adjusted by the hydraulic device on the body 100, and then the liquid in the stirring shaft 200 is sprayed out through the two spray ports 202 through the spray mechanism 400, so that the additives can directly enter the material in the container, thereby improving the mixing efficiency with the original material in the container.

[0026] Example 1

[0027] like Figure 3-4 As shown, in this embodiment, the ejection mechanism 400 includes:

[0028] A connecting shell 410 for injecting gas, two ejector tubes 450 and a bottom plate 440 for spraying additives, the inner wall of the connecting shell 410 is rotatably sleeved with the outer wall of the stirring shaft 200, the outer wall of the stirring shaft 200 is provided with multiple air inlet holes 203, and the interior of the multiple air inlet holes 203 are connected with the interior of the connecting shell 410, the outer walls of the two ejector tubes 450 are respectively slidably sleeved with the inner walls of the two ejection ports 202, the two ejector tubes 450 are both open at one end, and the other end of the outer wall of the two ejector tubes 450 is provided with multiple injection holes 452, the outer wall of the bottom plate 440 is fixedly sleeved with the inner wall of the stirring shaft 200, the top surface of the bottom plate 440 is fixedly connected with a fixed plate 441, and a return spring 451 is fixedly connected between the other end of the inside of the two ejector tubes 450 and the fixed plate 441.

[0029] In this embodiment, when the interior of the stirring shaft 200 is filled with liquid additives, gas can be injected into the stirring shaft 200 and the solenoid valve 330 can be closed so that the gas can push the other ends of the two ejection cylinders 450 in the stirring shaft 200 to be ejected from the two ejection ports 202. Then, as the gas continues to push, the liquid inside the stirring shaft 200 can be ejected from the multiple injection holes 452 by the gas, and the injection holes 452 have a small diameter, so that the liquid is in a thin stream after being ejected, which is easier to fully contact and mix with the material in the container, thereby improving the mixing efficiency.

[0030] like Figure 3-4As shown, in this embodiment, a connecting bucket 420 is fixedly connected to the inner wall of the stirring shaft 200, and a sliding tube 421 is fixedly connected to the bottom end of the connecting bucket 420, a piston plate 430 is slidingly connected to the inner wall of the stirring shaft 200, and a circular hole is opened in the center of the top surface of the piston plate 430, the circular hole is slidingly connected to the outer wall of the sliding tube 421, a connecting tube 411 is fixedly connected to the outer wall of the connecting shell 410, and the interior of the connecting tube 411 is connected to the interior of the connecting shell 410, and the top end of the connecting tube 411 is fixedly connected to the body 100 through a connecting frame.

[0031] During specific implementation, the liquid in the stirring shaft 200 flows into the space between the connecting bucket 420 and the bottom plate 440 only through the sliding pipe 421 through the connecting bucket 420. When in use, the connecting pipe 411 is connected to the air pump, and the air pump injects gas through the connecting pipe 411, and the solenoid valve 330 is closed. Then, the gas enters the space between the piston plate 430 and the connecting bucket 420 through the connecting shell 410 and the multiple air inlet holes 203. The gas will push the piston plate 430 down, causing the piston plate 430 to press the liquid between the piston plate 430 and the bottom plate 440, and the liquid pushes the two ejection cylinders 450 to eject, and the liquid is ejected from the multiple injection holes 452, and then the gas is extracted from the stirring shaft 200 through the connecting pipe 411. And open the solenoid valve 330, the two ejection cylinders 450 will be pulled by the return spring 451 to retract into the two nozzles 202, so that the multiple injection holes 452 are naturally blocked by the inner wall of the nozzle 202, and as the gas is extracted from the inside of the stirring shaft 200, the piston plate 430 is naturally reset due to the negative pressure generated by the gas extraction, and the liquid in the connecting bucket 420 is sucked into the space between the piston plate 430 and the bottom plate 440 through the sliding pipe 421, so that the gas does not contact the liquid in the stirring shaft 200, so that the gas is not easy to form bubbles and float to the top of the stirring shaft 200. The moving distance of the piston plate 430 can be adjusted by adjusting the amount of gas injected by the air pump, thereby adjusting the amount of liquid sprayed from the injection hole 452.

[0032] Example 2

[0033] On the basis of the first embodiment, a ball bearing is provided to make the stirring shaft 200 rotate more smoothly.

[0034] like Figure 2-4 As shown, in this embodiment, a plurality of ball bearings are provided inside the connecting shell 410 and the circular shell 310, and the connecting shell 410 and the circular shell 310 are fixedly sleeved with the outer rings of the adjacent ball bearings, and the inner ring of any ball bearing is fixedly sleeved with the outer wall of the stirring shaft 200, and the diameter of one end of the two ejection cylinders 450 is larger than the diameter of the ejection port 202.

[0035] During specific implementation, since the diameter of one end of the two ejector cylinders 450 is larger than that of the ejection port 202, the moving distance of the ejector cylinder 450 can be limited to prevent the ejector cylinder 450 from falling off from the ejection port 202. Since the stirring shaft 200 is in a state of continuous rotation during use, and the circular shell 310 is connected to the water tank via the conduit 320 and the pipeline, and the connection position of the connecting shell 410 and the body 100 via the connecting pipe 411 is fixed, the ball bearing can reduce the friction between the stirring shaft 200 and the circular shell 310 and the connecting shell 410 when the stirring shaft 200 rotates, thereby facilitating the rotation of the stirring shaft 200.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0037] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
