Detailed Implementation

[0025] Example 1, specifically as follows: Figures 1-8 As shown.

[0026] A solid-liquid homogenizing mixer includes a mixing cylinder 1 with a top opening and a cover plate 2 for opening and closing the mixing cylinder 1. The bottom of the mixing cylinder 1 is provided with a stirring structure 3, the cover plate 2 is provided with a spraying structure 4 for spraying liquid materials, and the inner wall of the mixing cylinder 1 is provided with a flow guiding structure 5.

[0027] like Figure 1 As shown, the mixing cylinder 1 is cylindrical in shape, with a stirring space inside. A support 101 is welded and fixed to the bottom of the mixing cylinder 1, and a receiving space is formed inside the support 101. In addition, a discharge port 102 is opened on the side wall at the bottom of the mixing cylinder 1, through which the mixed material is discharged. The cover plate 2 is located at the top opening of the mixing cylinder 1, and the two are rotatably connected. The cover plate 2 rotates in the horizontal direction, thereby realizing the opening and closing of the mixing cylinder 1. Specifically, a first connecting plate 203 is welded to one side of the cover plate 2, and a second connecting plate 103 is correspondingly welded to the outer side of the mixing cylinder 1. A rotating shaft 204 is provided between the first connecting plate 203 and the second connecting plate 103, and the two ends of the rotating shaft 204 are rotatably connected to the first connecting plate 203 and the second connecting plate 103, respectively.

[0028] The mixing drum 1 is equipped with a stirring structure 3 for stirring materials, such as... Figure 3 As shown, the stirring structure 3 is located at the bottom of the mixing cylinder 1. The stirring structure 3 includes a rotating rod 301 coaxial with the mixing cylinder 1 and stirring blades 302 distributed around the rotating rod 301. The inner ends of the stirring blades 302 are welded and fixed to the rotating rod 301. The stirring structure 3 also includes a motor 303 mounted on the bottom plate of the mixing cylinder 1. The motor 303 is located within the receiving space of the support 101, and the motor 303 is fixedly connected to the mixing cylinder 1 by screws. The bottom end of the rotating rod 301 extends vertically downward through the bottom plate of the mixing cylinder 1 and is fixedly connected to the output shaft of the motor 303. A coupling is used between the rotating rod 301 and the output shaft of the motor 303.

[0029] The cover plate 2 has a first inlet 201 for adding liquid materials at the center, and a plurality of second inlets 202 for adding solid materials are opened around the first inlet 201. In this embodiment, there are two second inlets 202, which are located on both sides of the first inlet 201.

[0030] The first feed inlet 201 is equipped with a spraying structure 4, such as Figure 1 , Figure 4As shown, the spraying structure 4 includes a pressure pump 401 located at the opening of the first feed inlet 201. The pressure pump 401 is connected and fixed to the upper surface of the cover plate 2 with screws. The water outlet of the pressure pump 401 is connected to a liquid outlet pipe 402, which passes through the first feed inlet 201 and extends into the stirring space inside the mixing cylinder 1. A nozzle 403 is provided at the water outlet of the liquid outlet pipe 402, and the two are threadedly connected. A liquid storage tank 404 is provided on one side of the pressure pump 401. The liquid storage tank 404 is welded and fixed to the cover plate 2 and is connected to the water inlet pipe of the pressure pump 401. The liquid storage tank 404 contains liquid material. By using the pressure pump 401 to transport and pressurize the liquid material in the liquid storage tank 404, and then spraying it out through the nozzle 403, the contact area of ​​the liquid material can be significantly increased, thereby improving the stirring effect from the source.

[0031] In other embodiments besides this one, the liquid storage tank 404 can be separated from the cover plate 2. For example, the liquid storage tank 404 can be placed on the ground, and the liquid storage tank 404 can be connected to the water inlet of the pressure pump 401 by a pipe.

[0032] like Figure 5 , Figure 6 As shown, the flow guiding structure 5 includes a flow guiding ring 501. The outer surface of the flow guiding ring 501 is tightly fitted to the inner wall of the mixing cylinder 1, and the inner surface of the flow guiding ring 501 is an inwardly inclined slope, meaning that the flow guiding ring 501 contracts inward from top to bottom. In this embodiment, the cross-section of the flow guiding ring 501 is a right-angled triangle, with its vertical surface in contact with the inner wall of the mixing cylinder 1 and its inclined surface facing inward. An annular liquid storage tank 502, concentric with the flow guiding ring 501, is provided inside the flow guiding ring 501. The cross-section of the liquid storage tank 502 is rectangular, and an inlet channel 503 is provided at the top of the inclined surface of the flow guiding ring 501. The inlet channel 503 is located outside the liquid storage tank 502 and extends vertically downward to the bottom of the liquid storage tank 502. The inlet channel 503 is connected to the bottom of the liquid storage tank 502.

[0033] The liquid storage tank 502 has an outlet channel 504 on the top side away from the inlet channel 503. The outlet channel 504 extends horizontally and penetrates the inclined surface of the guide ring 501, with its outlet located at the waist of the inclined surface of the guide ring 501. It is worth emphasizing that multiple outlet channels 504 are arranged at intervals, forming a non-continuous overall structure.

[0034] Multiple sets of baffles are arranged sequentially from top to bottom along the height direction on the inclined surface below the liquid outlet channel 504. In this embodiment, there are 3 sets of baffles, specifically the first baffle 505, the second baffle 506 and the third baffle 507. It is worth emphasizing that, in terms of size, the length of the three sets of spoilers gradually increases and the height gradually decreases from top to bottom; in terms of density, the density of the three sets of spoilers gradually increases from top to bottom. The first channel between adjacent first spoilers 505 is divided by two second spoilers 506, forming a complete second channel and incomplete second channels located on both sides of the complete second channel. The width of the incomplete second channel is half the width of the complete second channel. The second channel between adjacent second spoilers 506 on both sides is divided by three third spoilers 507. The third spoilers 507 on both sides are directly opposite the second spoilers 506 on both sides along the length direction. The third spoiler 507 in the middle evenly divides the complete second channel into two third channels. The width of the third channel is half the width of the second channel.

[0035] Multiple mounting grooves are also formed along the circumference on the vertical surface of the guide ring 501 that contacts the inner wall of the mixing cylinder 1. A magnetic piece 508 is glued into the mounting groove. The size of the magnetic piece 508 is the same as the size of the mounting groove. The guide ring 501 is connected to the mixing cylinder 1 by the magnetic force between the magnetic piece 508 and the mixing cylinder 1. The height of the guide ring 501 can be adjusted. On the one hand, it can be adjusted according to the volume of the mixture to prevent the guide ring 501 from affecting the mixing of the mixture. On the other hand, it can also be adjusted according to the spray force of the nozzle 403. In particular, when the spray force is small, the height of the guide ring 501 needs to be lowered to ensure that the guide ring 501 is below the position where the liquid material contacts the mixing cylinder 1.

[0036] The liquid sprayed onto the inner wall of the mixing cylinder slides down under the influence of gravity and possesses a certain kinetic energy. Through the design of the guide structure 5, on the one hand, the falling liquid flows into the storage tank 502 through the inlet channel 503, where it is buffered and some of its kinetic energy is consumed. Then, it flows out through the outlet channel 504 and is further divided into smaller units by three sets of baffles, thereby increasing its contact area and making its mixing with the solids more uniform. On the other hand, the guide ring 501 can effectively intercept the liquid on the inner wall, preventing the liquid from sliding down to the bottom of the mixing cylinder and preventing the "sinking" phenomenon from the source.

[0037] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
