Description

Technical Field

[0001] This utility model relates to the field of water-reducing agent preparation, specifically a reaction vessel for preparing water-reducing agents. Background Technology

[0002] Water-reducing agents are concrete admixtures that reduce the amount of water used in mixing while maintaining the slump of the concrete. Most of them are anionic surfactants, such as lignin sulfonates, naphthalene sulfonates, and formaldehyde polymers. When added to concrete mixtures, they disperse cement particles, improve workability, reduce unit water consumption, and improve the fluidity of the concrete mixture.

[0003] In the prior art, when preparing water-reducing agents, it is generally necessary to add a certain amount of powdered raw materials into the reaction vessel. In order to improve the reaction efficiency and increase the diffusion of the powdered raw materials, the raw materials are generally stirred by a stirring motor driving a stirring rod between the input of the raw materials, so as to completely mix the input raw materials. However, the existing stirring direction is unidirectional, and the raw materials in the gap between the two stirring rods have relatively weak turbulence during the stirring process. There is room for further improvement in stirring efficiency, and it is not possible to stir the raw materials at different depths alternately. Based on this, this utility model proposes a reaction vessel for preparing water-reducing agents. Utility Model Content

[0004] The purpose of this invention is to provide a reaction vessel for preparing water-reducing agents in order to solve the problems mentioned in the background.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a reaction vessel for preparing a water-reducing agent, comprising a reaction vessel, and further comprising a feed pipe and a discharge pipe respectively disposed at the top and bottom of the reaction vessel, wherein the feed pipe is used to guide the input of raw materials, the discharge pipe is used to guide the discharge of raw materials after stirring, and further comprising a stirring mechanism disposed on the reaction vessel for stirring the raw materials;

[0006] The stirring mechanism includes a stirring unit and a guiding unit;

[0007] The stirring unit is used to stir and mix the raw materials inside the reactor;

[0008] The guide unit is used to increase the stirring range of the stirring unit.

[0009] As a further embodiment of this utility model: the stirring unit includes a stirring motor, a transmission rod, a rotating rod, a stirring rod, and a docking groove;

[0010] The stirring motor is installed at the top axial position of the reactor. The output end of the stirring motor extends into the interior of the reactor and is connected to a transmission rod. The transmission rod is inserted into the cavity of the docking groove opened at the top of the rotating rod. The transmission rod transmits the rotational force from the stirring motor through the protrusion on the outer wall to drive the rotating rod to rotate. Multiple stirring rods for stirring the raw materials inside the reactor are fixed laterally on the outer wall of the rotating rod.

[0011] As a further embodiment of this utility model: the guide unit includes a protective sleeve, a guide ring, and a guide rod;

[0012] The protective sleeve is fixed to the top of the inner cavity of the reactor and surrounds the connection between the transmission rod and the rotating rod. A guide ring is fixed in the inner cavity of the protective sleeve. Half of the guide ring is in an inclined semi-circular state, and the other half is in a straight semi-circular state. The guide rod is rotatably connected to the outer wall of the rotating rod and extends above the guide ring.

[0013] As a further improvement of this utility model, the inner cavity of the protective sleeve is movably connected to the outer wall of the rotating rod.

[0014] As a further improvement of this utility model, the inner cavity of the docking groove matches the outer wall of the transmission rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By setting up a stirring mechanism, when the stirring rod is driven by the stirring motor to stir and mix the raw materials in the reactor, the stirring rod will move up and down synchronously under the action of the guide ring and guide block during the circumferential rotation, which further increases the stirring range of the stirring rod, enhances the turbulence speed in the stirring process of raw materials at different depths, improves stirring efficiency, and further increases the mixing speed of the raw materials.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 In this embodiment of the present invention, a reaction vessel for preparing a water-reducing agent includes a reaction vessel 1, and further includes a feed pipe 2 and a discharge pipe 3 respectively disposed at the top and bottom of the reaction vessel 1. The feed pipe 2 is used to guide the input of raw materials, and the discharge pipe 3 is used to guide the discharge of raw materials after stirring. It also includes a stirring mechanism 4 disposed on the reaction vessel 1 for stirring the raw materials.

[0023] The stirring mechanism 4 includes a stirring unit and a guiding unit;

[0024] The stirring unit is used to stir and mix the raw materials inside the reactor 1;

[0025] The guide unit is used to increase the stirring range of the stirring unit;

[0026] The stirring unit includes a stirring motor 401, a transmission rod 402, a rotating rod 403, a stirring rod 404, and a docking groove 408;

[0027] The stirring motor 401 is installed at the top axial position of the reactor 1. The output end of the stirring motor 401 extends into the interior of the reactor 1 and is connected to the transmission rod 402. The transmission rod 402 is inserted into the inner cavity of the docking groove 408 opened at the top of the rotating rod 403. The transmission rod 402 transmits the rotational power from the stirring motor 401 through the outer wall protrusion to drive the rotating rod 403 to rotate. Multiple stirring rods 404 for stirring the raw materials inside the reactor 1 are fixed laterally on the outer wall of the rotating rod 403.

[0028] The guide unit includes a protective sleeve 405, a guide ring 406, and a guide rod 407;

[0029] The protective sleeve 405 is fixed to the top of the inner cavity of the reactor 1, and the protective sleeve 405 surrounds the connection between the transmission rod 402 and the rotating rod 403. The inner cavity of the protective sleeve 405 is fixed with a guide ring 406. Half of the guide ring 406 is in an inclined semi-circular state, and the other half is in a straight semi-circular state. The guide rod 407 is rotatably connected to the outer wall of the rotating rod 403, and the guide rod 407 extends above the guide ring 406.

[0030] In this embodiment: Through this structure, the raw materials to be added can be added into the interior of the reactor 1 through the feed pipe 2. By starting the stirring motor 401, the operation of the stirring motor 401 will synchronously drive the transmission rod 402 connected to the output end to rotate. The rotating transmission rod 402 provides rotational thrust to the docking groove 408 through the protrusion on the outer wall, so that the docking groove 408 transmits the rotational force to the rotating rod 403, so that the rotating rod 403 synchronously drives the stirring rod 404 to rotate circumferentially, thereby stirring the raw materials inside the reactor 1.

[0031] During the rotation of the rotating rod 403, the guide rod 407, which is rotatably connected to the outer wall of the rotating rod 403, will also rotate synchronously in the circumferential direction. This causes the guide rod 407 to move along the upper surface of the guide ring 406. The guide rod 407 will move from the lower end to the upper end of the inclined semicircular ring of the guide ring 406. The moving guide rod 407 will synchronously drive the rotating rod 403 and the stirring rod 404 to move upward. This causes the rotating rod 403 and the stirring rod 404 to move upward synchronously during the circumferential rotation. When the guide rod 407 moves to the highest end of the guide ring 406, it will fall to the bottom end of the guide ring 406, i.e., the initial end, due to its own weight and gravity. This process is repeated, thereby increasing the stirring range of the stirring rod 404 and further improving the stirring efficiency.

[0032] Please refer to this carefully. Figures 1-3 The inner cavity of the protective sleeve 405 is movably connected to the outer wall of the rotating rod 403, and the inner cavity of the mating groove 408 matches the outer wall of the transmission rod 402.

[0033] In this embodiment: With this structure, when the rotating rod 403 moves along the outer wall of the guide ring 406 via the guide rod 407, the transmission rod 402 will also move relative to it along the inner cavity of the docking groove 408, providing space for the up-and-down reciprocating movement of the rotating rod 403.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
