[0026] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0027] Example 1

[0028] Reference Figure 1-4This is the first embodiment of the present invention, which provides a mixing chamber 1, with a support leg 2 fixedly connected to the bottom of the mixing chamber 1, a discharge pipe 3 fixedly connected to the bottom of the mixing chamber 1, a feed pipe 14 fixedly connected to the right side of the mixing chamber 1, a motor 4 installed at the top of the mixing chamber 1, an output shaft at the bottom of the motor 4 extending into the inner cavity of the mixing chamber 1 and fixedly connected to a rotating rod 5, a stirring rod 6 fixedly connected to the surface of the rotating rod 5, a crushing mechanism 7 installed inside the mixing chamber 1, and a vibration mechanism 8 installed at the top of the mixing chamber 1.

[0029] The crushing mechanism 7 is used to crush the clumps of dialysis powder raw material, thereby improving the uniformity of mixing;

[0030] The vibration mechanism 8 is used to strike the mixing box 1 to transmit the vibration to the crushing mechanism 7, which facilitates the feeding of the crushing mechanism 7 and prevents blockage.

[0031] Specifically, the mixing rod 6 achieves basic mixing of raw materials, the crushing mechanism 7 solves the problem of clumping, and the vibration mechanism 8 prevents the screen plate 701 from clogging, thus improving the overall mixing uniformity.

[0032] Furthermore, the mixing chamber 1 provides space for mixing dialysis powder raw materials. The raw materials enter the mixing chamber 1 through the feed pipe 14. After the motor 4 is started, its output shaft drives the rotating rod 5 and the surface stirring rod 6 to rotate, thus mixing the raw materials. The crushing mechanism 7 can process the lumpy parts in the raw materials into loose parts. The vibration mechanism 8 transmits the vibration to the crushing mechanism 7 by tapping the mixing chamber 1, which assists the raw materials to fall.

[0033] A fixing block 13 is fixedly connected to the top of the motor 4, and the rear side of the fixing block 13 is fixedly connected to the electric telescopic rod 702. The fixing block 13 is used to support the motor 4, making the motor 4 stable and improving the stability of the stirring and vibration mechanism 8.

[0034] Example 2

[0035] In the second embodiment of this utility model, a crushing mechanism 7 is provided, including a sieve disc 701 rotatably connected to the surface of a rotating rod 5 via a bearing. The periphery of the sieve disc 701 is fixedly connected to the inner wall of the mixing box 1. An electric telescopic rod 702 is fixedly connected to the top of the mixing box 1. The telescopic end of the electric telescopic rod 702 extends into the inner cavity of the mixing box 1 and is fixedly connected to a pressure plate 703. The surface of the pressure plate 703 slides in contact with the inner wall of the sieve disc 701. The pressure plate 703 is sleeved on the outer periphery of the rotating rod 5, and the surface of the rotating rod 5 does not contact the inner wall of the pressure plate 703.

[0036] Specifically, it effectively ensures that the raw material particles entering the mixing stage are uniform, avoids the formation of clumps of raw materials, and improves the uniformity of mixing.

[0037] Furthermore, the raw materials are poured into the mixing box 1 in proportion through the feed inlet. The raw materials will first fall onto the screen plate 701. When the lumpy raw materials fall onto the screen plate 701, the lumpy raw materials will remain on the screen plate 701, while the unlumpy materials will fall downwards with the assistance of the screen holes of the screen plate 701 and the vibration mechanism 8. When the lumpy materials accumulate to a certain amount, the electric telescopic rod 702 is activated. The electric telescopic rod 702 drives the pressure plate 703 to move downwards, which can crush the lumps.

[0038] Example 3

[0039] The second embodiment of this utility model provides a vibration mechanism 8 including a missing gear 801 fixedly sleeved on the surface of the bottom output shaft of the motor 4. The missing gear 801 meshes with a rack 802. One end of the rack 802 is fixedly connected to a tension spring 803, and the other end of the tension spring 803 is fixedly connected to a vertical plate 804. The bottom of the vertical plate 804 is fixedly connected to the top of the mixing box 1. The other end of the rack 802 is fixedly connected to a vertical rod 805. One side of the vertical rod 805 is fixedly connected to a first striking element 806, and one end of the first striking element 806 contacts the mixing box 1.

[0040] Specifically, the vibration generated by the knocking causes the raw material on the screen plate 701 to pass through the screen holes quickly, preventing the raw material from clogging the screen plate 701 and ensuring smooth material feeding of the crushing mechanism 7.

[0041] Furthermore, when the output shaft of motor 4 rotates, it drives the missing gear 801 to rotate synchronously, and the missing gear 801 alternately meshes with the rack 802; when meshing, it pushes the rack 802 to move away from the vertical plate 804, and the tension spring 803 is stretched; when the missing gear 801 disengages, the tension spring 803 returns to its original position and pulls the rack 802 to move in the opposite direction, so that the rack 802 performs reciprocating motion; the rack 802 drives the vertical rod 805 and the first striking element 806 to move synchronously, and the first striking element 806 repeatedly strikes the mixing box 1, and the vibration is transmitted to the screen plate 701 of the crushing mechanism 7 through the mixing box 1.

[0042] The rack 802 has a sliding hole 9 inside, and a slide rod 10 is slidably connected to the inner wall of the sliding hole 9. One end of the slide rod 10 extends to the outside of the sliding hole 9 and is fixedly connected to the vertical plate 804. A tension spring 803 is sleeved on the surface of the slide rod 10. When the rack 802 reciprocates, the slide rod 10 slides synchronously in the sliding hole 9. The tension spring 803 sleeved on the surface of the slide rod 10 prevents the tension spring 803 from shifting when deformed, which helps to extend the service life of the tension spring 803.

[0043] A limiting block 11 is fixedly connected to the bottom of the rack 802, and the bottom of the limiting block 11 is slidably connected to the top of the mixing box 1 through a sliding groove. When the rack 802 reciprocates, the limiting block 11 at its bottom slides synchronously in the sliding groove at the top of the mixing box 1, which helps to enhance the stability of the rack 802's movement.

[0044] A second striking element 12 is fixedly connected to one side of the vertical rod 805, and one end of the second striking element 12 contacts the surface of the feed tube. The reciprocating motion of the rack 802 drives the vertical rod 805 to move synchronously. The second striking element 12 on one side of the vertical rod 805 repeatedly strikes the surface of the feed tube with the vertical rod 805 to prevent the raw material from accumulating and blocking inside the feed tube.

[0045] Working principle:

[0046] Raw materials are poured into mixing tank 1 through the feed inlet according to the ratio. Motor 4 is started, and its output shaft drives rotating rod 5 and surface stirring rod 6 to rotate, mixing the raw materials. The raw materials first fall onto screen plate 701. When lumpy raw materials fall onto screen plate 701, the lumps remain on screen plate 701, while unlumped materials fall downwards with the assistance of screen holes in screen plate 701 and vibration mechanism 8. When a certain amount of lumpy material accumulates, electric telescopic rod 702 is activated. Electric telescopic rod 702 drives pressure plate 703 downwards to crush the lumps, effectively ensuring uniform particle size of raw materials entering the mixing stage, avoiding lumps, and improving mixing uniformity. When the output shaft of motor 4 rotates, it drives gear 801 to rotate synchronously. Gear 801 alternately meshes with rack 802; during meshing, it pushes rack 802 away from vertical plate 804, stretching tension spring 803; gear 801... When disengaged, the tension spring 803 resets and pulls the rack 802 in the opposite direction, causing the rack 802 to reciprocate. The rack 802 drives the vertical rod 805 and the first striking element 806 to move synchronously. The first striking element 806 repeatedly strikes the mixing box 1, and the vibration is transmitted to the screen plate 701 of the crushing mechanism 7 through the mixing box 1. The vibration generated by the striking causes the raw material on the screen plate 701 to pass through the screen holes quickly, preventing the raw material from clogging the screen plate 701 and ensuring smooth material feeding of the crushing mechanism 7. When the rack 802 reciprocates, the slide rod 10 slides synchronously in the slide hole 9. The tension spring 803 is sleeved on the surface of the slide rod 10 to prevent the tension spring 803 from shifting when deformed, which helps to extend the service life of the tension spring 803. The reciprocating motion of the rack 802 drives the vertical rod 805 to move synchronously. The second striking element 12 on one side of the vertical rod 805 repeatedly strikes the surface of the feed pipe along with the vertical rod 805, striking the feed pipe to prevent the raw material from accumulating and clogging in the feed pipe.

[0047] In summary, the combination of the crushing and vibration mechanisms enables efficient dispersal of agglomerated raw materials, effectively improving the uniformity of mixing and the quality of the final product.
