Description

Technical Field

[0001] This utility model relates to the field of sepiolite hemostatic material processing technology, specifically a mixing and stirring device for processing sepiolite hemostatic materials. Background Technology

[0002] Sepiolite, a natural nano-porous silicate mineral, has significant application value in the field of hemostatic materials due to its excellent adsorption, ion exchange, and biocompatibility. In the production and processing of sepiolite hemostatic materials, sepiolite powder needs to be mixed with other liquid additives (such as hemostatic active liquids).

[0003] However, existing mixing equipment has the following technical problems in the processing:

[0004] (1) Traditional single blades (such as straight blades and inclined blades) have limited mixing effect on powdered sepiolite, making it difficult to achieve full mixing of powder and liquid materials. They are prone to dead zones in the mixing process, resulting in uneven distribution of sepiolite and additives and low mixing efficiency.

[0005] (2) Sepiolite powder is prone to absorbing moisture and agglomerating, and conventional stirring is not effective in breaking up the agglomerates;

[0006] (3) The material is prone to bridging and blockage when it is discharged, which affects the continuity of production.

[0007] These problems directly or indirectly affect the performance stability and batch consistency of hemostatic materials, and there is an urgent need to develop specialized mixing equipment to solve key technical problems such as material uniformity, agglomeration treatment, and smooth discharge. Utility Model Content

[0008] The purpose of this invention is to provide a mixing and stirring device for processing sepiolite hemostatic materials, so as to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a mixing and stirring device for processing sepiolite hemostatic materials, comprising a mixing tank, a stirring shaft mounted on the top of the mixing tank via a bearing, a stirring motor drivenly connected to the top of the stirring shaft, and a main stirring blade mounted on the bottom of the stirring shaft, a mounting base mounted on the stirring shaft above the main stirring blade, the mounting base being rotatably connected to the inner wall of the mixing tank via a sealed bearing, an auxiliary shaft being annularly mounted on the mounting base via a bearing, an auxiliary blade mounted on the auxiliary shaft, and an auxiliary rotation structure being provided between the auxiliary shaft and the inner wall of the mixing tank, a discharge hopper being provided at the bottom of the mixing tank, a vibrator being installed at the discharge hopper, a discharge pipe being provided at the bottom of the discharge hopper, and a feeding structure being provided on the mixing tank.

[0010] The present invention is further configured such that the feeding structure includes a feeding pipe, which is disposed on the side wall of the mixing tank and located below the mounting base. Here, the feeding pipe is connected to the outlet of the external sepiolite powder storage tank. The feeding and conveying of sepiolite powder can be achieved through existing negative pressure suction technology. In conjunction with the butterfly valve sealing structure, the sepiolite powder is sucked from the storage tank into the mixing chamber of the mixing tank by a vacuum pump, avoiding dust leakage caused by manual dumping.

[0011] The present invention is further configured such that the feeding structure includes an annular spray pipe, which is located below the mounting base and sleeved around the auxiliary shaft. Multiple nozzles are evenly arranged on the annular spray pipe, and a liquid inlet pipe is provided on the annular spray pipe, extending to the outside of the mixing tank. Liquid additives are transported to the annular spray pipe through the liquid inlet pipe and evenly sprayed out through the atomizing nozzles. This allows for uniform spraying of the liquid additives onto the sepiolite powder during feeding, thereby improving feeding uniformity and subsequent mixing efficiency. Here, the liquid inlet pipe is connected to the liquid source of the liquid additives, and the conveying power can be achieved through a pump.

[0012] The present invention is further configured such that the auxiliary rotation structure includes a gear, which is installed at the top of the auxiliary shaft. A rack is arranged around the top inner wall of the mixing tank. The gear meshes with the rack. When the mixing shaft drives the main mixing blade to tumble and mix the sepiolite and liquid additives, it will drive the mounting base to rotate synchronously. The mounting base will drive the auxiliary shaft to revolve around the axis of the mixing shaft. At this time, the auxiliary shaft will drive the auxiliary blade to revolve around the axis of the mixing shaft. Simultaneously, during the process of the mounting base driving the auxiliary shaft to revolve, the gear at the top of the auxiliary shaft will rotate on its own axis under the action of meshing with the rack. This allows the auxiliary blade to rotate on its own axis while revolving around the mixing shaft, thereby enhancing the tumbling effect on the periphery of the mixing space inside the mixing tank. This, in conjunction with the main mixing blade, enhances the flow and shearing effect of the sepiolite mixture in the mixing tank, thereby improving the mixing efficiency.

[0013] The present invention is further configured such that a protective space is formed between the upper part of the mounting base and the inner top wall of the mixing tank, and the gear and rack are both located within the protective space. In this way, the structure of the gear and rack can be isolated from the sepiolite mixture, reducing the adhesion and residue of materials between the gear and rack, and improving the overall rotational smoothness and mixing smoothness.

[0014] The present invention is further configured such that a cutting seat is provided on the stirring shaft and in the middle of the main stirring blade, and a plurality of cutting blades are evenly arranged on the cutting seat. When the stirring shaft drives the main stirring blade to control the material to rise or fall, the material will flow through the cutting blades, thereby cutting the sepiolite agglomerates carried therein, and breaking the sepiolite agglomerates through shearing force (especially for raw materials that have become damp and agglomerated).

[0015] The present invention is further configured such that the bottom end of the stirring shaft extends into the discharge pipe and is provided with a spiral discharge blade. During discharge, the stirring shaft drives the spiral discharge blade to rotate, thereby assisting in the discharge and preventing the sepiolite mixture from forming a "bridging" phenomenon at the discharge pipe, which would cause arched blockage or irregularities at the discharge pipe.

[0016] The present invention is further provided that a discharge control valve is provided at the discharge pipe, the discharge control valve being used to control the opening and closing of the discharge pipe and the discharge flow rate.

[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. Improved mixing efficiency and uniformity.

[0018] This invention achieves efficient mixing of sepiolite materials through the synergistic action of the main and auxiliary stirring blades. The main stirring blade reciprocates under the drive of the stirring shaft, circulating the material up and down. Simultaneously, the auxiliary blade rotates on its own axis while revolving around the central axis via a gear-rack structure, enhancing the shearing and tumbling of the material around the mixing tank. The combined effect of the two blades creates a three-dimensional mixing flow field, significantly shortening the mixing time, preventing localized accumulation, ensuring full contact between the sepiolite and liquid additives, and improving the uniformity of the hemostatic material composition. Furthermore, the cutting blade can break up clumps of material, further optimizing the mixing effect.

[0019] 2. Optimization of feeding and discharging processes

[0020] This invention employs a feeding structure combining negative pressure suction and annular spraying. While sepiolite powder is drawn in through the feed pipe, liquid additives are evenly sprayed through atomizing nozzles, achieving precise simultaneous powder and liquid feeding and reducing the burden of subsequent mixing. During discharge, the spiral discharge blades, in conjunction with a high-frequency vibrator, effectively prevent material from forming bridging blocks in the discharge pipe, ensuring smooth discharge. The sealed bearing and protective space design prevents material adhesion to the gear transmission structure, ensuring long-term operational stability. Attached Figure Description

[0027] 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.

[0028] This utility model provides a technical solution: Please refer to Figures 1-5 A mixing and stirring device for processing sepiolite hemostatic material includes a mixing tank 1. A stirring shaft 2 is mounted on the top of the mixing tank 1 via a bearing. A stirring motor 3 is drivenly connected to the top of the stirring shaft 2, and a main stirring blade 4 is mounted on the bottom. A mounting base 5 is mounted on the stirring shaft 2 above the main stirring blade 4. The mounting base 5 is rotatably connected to the inner wall of the mixing tank 1 via a sealed bearing. An auxiliary shaft 6 is annularly mounted on the mounting base 5 via a bearing. An auxiliary blade 7 is mounted on the auxiliary shaft 6, and an auxiliary rotation structure is provided between the auxiliary shaft 6 and the inner wall of the mixing tank 1. A discharge hopper 8 is provided at the bottom of the mixing tank 1, and a vibrator 9 is installed at the discharge hopper 8. A discharge pipe 10 is provided at the bottom of the discharge hopper 8. A feeding structure is provided on the mixing tank 1.

[0029] Please see Figures 1-5As one implementation of the feeding structure: the feeding structure includes a feeding pipe 11, which is set on the side wall of the mixing tank 1 and located below the mounting base 5. Here, the feeding pipe 11 is connected to the outlet of the external sepiolite powder storage tank. The feeding and conveying of sepiolite powder can be realized by existing negative pressure suction technology. In conjunction with the butterfly valve sealing structure, the sepiolite powder is sucked from the storage tank into the mixing chamber of the mixing tank 1 by a vacuum pump, avoiding dust leakage caused by manual dumping. The use of negative pressure to convey powder for feeding is existing technology, which should be known to those skilled in the art, and this utility model will not elaborate further.

[0030] Please see Figures 1-5 As one implementation of the feeding structure: the feeding structure also includes an annular spray pipe 12, which is located below the mounting base 5 and sleeved around the auxiliary shaft 6. Multiple nozzles 13 are evenly arranged on the annular spray pipe 12, and a liquid inlet pipe 14 is provided on the annular spray pipe 12. The liquid inlet pipe 14 extends to the outside of the mixing tank 1, and the liquid additive is transported to the annular spray pipe 12 through the liquid inlet pipe 14 and evenly sprayed out through the atomizing nozzles 13. In this way, the liquid additive can be evenly sprayed on the sepiolite powder during feeding, thereby improving the feeding uniformity and subsequent stirring and mixing efficiency. Here, the liquid inlet pipe 14 is connected to the liquid source of the liquid additive, and the conveying power can be realized by the pump body.

[0031] Please see Figures 1-5 As one implementation of the auxiliary rotating structure: the auxiliary rotating structure includes a gear 15, which is installed at the top of the auxiliary shaft 6. A rack 16 is arranged around the top inner wall of the mixing tank 1. The gear 15 meshes with the rack 16. When the stirring shaft 2 drives the main stirring blade 4 to stir and mix the sepiolite and liquid additives, it will drive the mounting base 5 to rotate synchronously. The mounting base 5 will drive the auxiliary shaft 6 to revolve around the axis of the stirring shaft 2. At this time, the auxiliary shaft 6 will drive the auxiliary blade 7 to revolve around the axis of the stirring shaft 2. At the same time, during the process of the mounting base 5 driving the auxiliary shaft 6 to revolve, the gear 15 at the top of the auxiliary shaft 6 will rotate under the action of meshing with the rack 16. Thus, the auxiliary blade 7 will rotate on its own axis while revolving around the stirring shaft 2, thereby strengthening the stirring effect on the periphery of the mixing space inside the mixing tank 1. In this way, in conjunction with the main stirring blade 4, the flow shearing effect of the sepiolite mixture in the mixing tank 1 is strengthened, and the mixing efficiency is improved.

[0032] In this invention, a protective space 17 is formed between the top of the mounting base 5 and the inner top wall of the mixing tank 1. The gear 15 and the rack 16 are both located within the protective space 17. This allows the structure of the gear 15 and the rack 16 to be isolated from the sepiolite mixture, reducing the adhesion and residue of materials between the gear 15 and the rack 16, and improving the overall rotational smoothness and mixing smoothness.

[0033] Please see Figures 1-5 As one embodiment of the stirring shaft 2: a cutting seat 18 is provided on the stirring shaft 2 and in the middle of the main stirring blade 4. Multiple cutting blades 19 are evenly arranged on the cutting seat 18. During the process of the stirring shaft 2 driving the main stirring blade 4 to control the material to rise or fall, the material will flow through the cutting blades 19, thereby cutting the sepiolite agglomerates carried therein, and breaking the sepiolite agglomerates through shearing force (especially for raw materials that have become damp and agglomerated).

[0034] In this invention, the bottom end of the stirring shaft 2 extends into the discharge pipe 10 and is provided with a spiral discharge blade 20. During discharge, the stirring shaft 2 controls the rotation of the spiral discharge blade 20, which can assist in discharge and prevent the sepiolite mixture from forming a "bridging" phenomenon at the discharge pipe 10, which would cause arched blockage or irregularities at the discharge pipe 10.

[0035] Please see Figures 1-5 As one implementation of the discharge pipe 10: a discharge control valve 21 is provided at the discharge pipe 10. The discharge control valve 21 is used to control the opening and closing of the discharge pipe 10 and the discharge flow rate.

[0036] In summary, the working principle and specific workflow of this utility model are as follows:

[0037] In use, this utility model feeds sepiolite powder through the feed pipe 11 and liquid additives through the liquid inlet pipe 14, so that the liquid and sepiolite powder enter the mixing tank 1 in a uniform proportion, thereby improving the uniformity of feeding, reducing the time required for subsequent mixing, and improving the mixing and stirring efficiency.

[0038] When stirring, start the stirring motor 3. The stirring motor 3 can control the stirring shaft 2 to drive the main stirring blade 4 to rotate back and forth.

[0039] During this process, the stirring shaft 2 will synchronously drive the mounting base 5 to rotate, and the mounting base 5 will drive the auxiliary shaft 6 to revolve along the stirring shaft 2, thereby causing the auxiliary blade 7 to revolve along the axis of the stirring shaft 2.

[0040] During this process, the gear 15 at the top of the auxiliary shaft 6 will rotate under the meshing action with the rack 16, so that the auxiliary blade 7 will rotate while revolving around the stirring shaft 2, thereby enhancing the stirring effect of the mixing space outside the mixing tank 1.

[0041] When the main stirring blade 4 conveys the sepiolite mixture upwards, the auxiliary blade 7 will convey the sepiolite mixture downwards from the outside, thereby causing the sepiolite mixture to circulate back and forth in the mixing tank 1.

[0042] When the main stirring blade 4 rotates in the opposite direction to convey the sepiolite mixture downwards, the auxiliary blade 7 will also change the conveying direction, thereby cooperating with the main stirring blade 4 to enhance the flow shearing effect of the sepiolite mixture in the mixing tank 1 and improve the mixing efficiency.

[0043] When the sepiolite mixture needs to be discharged after the mixing is completed, the discharge control valve 21 is opened, and the stirring shaft 2 will drive the spiral discharge blade 20 to rotate, so that the sepiolite mixture can be discharged smoothly.

[0044] During the above discharge process, the vibrator 9 can be started. The vibrator 9 is preferably a high-frequency vibrator. In this way, the vibration will cause the material to slide down naturally, reducing the residue of the sepiolite mixture in the mixing tank 1 and improving the discharge effect.

[0045] This utility model only describes the corresponding improved structure in response to the technical problems raised in the background section; the parts not described can be implemented using existing technology.

[0046] All parts of this invention involving bearing installation that require sealing can be achieved using existing mechanical seal structures.
