Description

Technical Field

[0001] This utility model relates to the field of material mixing equipment technology, and in particular to a multi-functional mixing tank suitable for simultaneously mixing and stirring powder and solid particulate materials. Background Technology

[0002] In various industries such as building materials, metallurgy, and mining solid waste resource utilization, it is frequently necessary to mix powdered materials with solid granular materials. However, existing equipment has significant shortcomings: First, it is not specialized enough; powder mixing equipment struggles to agitate coarse and heavy particles, easily creating sedimentation dead zones, while granular mixing equipment lacks sufficient powder dispersion capabilities and easily generates dust. Second, uneven mixing often results in powder stratification and agglomeration, severely impacting product performance. Third, poor sealing leads to dust leakage during powder mixing, causing pollution and material loss. Fourth, severe wear and tear is a concern; hard particles exacerbate equipment wear and increase maintenance costs. Therefore, a dedicated mixing device is urgently needed to achieve efficient, uniform, and dust-free mixing of powders and granules, which is crucial for promoting the resource utilization of mining solid waste and improving the quality of building materials. Utility Model Content

[0003] This invention provides a multi-functional mixing tank for powders and solid particles, capable of simultaneously and efficiently dispersing and shearing powdery materials such as slag powder to prevent agglomeration and dust generation, and thoroughly agitating solid granular materials such as waste rock aggregate to prevent sedimentation, achieving uniform mixing of the two types of substances. Furthermore, the equipment exhibits excellent sealing and wear resistance.

[0004] The technical solution of this utility model is as follows: A multi-functional mixing tank for powders and solid particles includes a tank body, a sealing cover, a stirring shaft, a power unit, and a combined stirrer; The sealing cap is detachably connected to the top of the barrel; The stirring shaft is vertically installed inside the barrel and is driven to rotate by a power device; The combined agitator is mounted on the agitator shaft; The combined mixer has a two-layer design: the upper mixing component is located in the upper part of the barrel and is used to strongly disperse powder to avoid clumping and dust. The lower mixing component is located in the lower middle part of the tank and is used to fully agitate the waste stone aggregate to prevent sedimentation. The bottom of the barrel is equipped with a discharge port and a sampling port.

[0005] The preferred embodiment of the multifunctional mixing tank for powders and solid particles is that the upper mixing assembly includes at least one high-speed shear mixer, wherein the high-speed shear mixer has serrated blades.

[0006] The preferred embodiment of the multifunctional mixing tank for powders and solid particles is that the lower mixing assembly includes at least one low-speed, high-torque agitator, wherein the low-speed, high-torque agitator is a ribbon agitator.

[0007] The preferred embodiment of the multifunctional mixing tank for powders and solid particles is that the mixing shaft has a hollow structure, and a cooling or heating medium can be introduced into its interior; the side wall of the tank is provided with a jacket, and a cooling or heating medium can be introduced into the jacket.

[0008] The preferred embodiment of the multifunctional mixing tank for powder and solid particles is that the sealing cover is provided with an observation window and a feed inlet with a sealing ring.

[0009] The preferred embodiment of the multifunctional mixing tank for powder and solid particles is that the inner wall of the tank is detachably provided with a wear-resistant liner, the wear-resistant liner being made of a polymer material or a metal-ceramic composite material.

[0010] The preferred embodiment of the multifunctional mixing tank for powders and solid particles is that the power unit is a variable frequency motor, and the rotational speed of the mixing shaft is adjustable.

[0011] The preferred embodiment of the multifunctional mixing tank for powders and solid particles is that the bottom of the tank is conical.

[0012] The beneficial effects of this utility model are as follows: It adopts a combined layered mixing mechanism, with a high-speed shear mixer in the upper layer powerfully dispersing powders such as slag micro-powder, and a low-speed, high-torque mixer in the lower layer fully agitating solid particles such as waste rock aggregate, achieving efficient and uniform mixing of the two types of materials. This effectively solves the problems of powder agglomeration, particle sedimentation, and mixing stratification, making it suitable for scenarios such as mining backfill materials and building aggregate mixing. One machine can meet the mixing needs of powders and particles, eliminating the need for specialized equipment and saving equipment investment and space. The sealed cover design prevents dust from escaping, protecting the working environment and reducing material loss. Optional wear-resistant liners can significantly extend the service life of the equipment when mixing hard and abrasive particles, reducing maintenance costs. Equipped with a variable frequency motor, the mixing speed can be flexibly adjusted, and a temperature control function can also be selected to adapt to different material characteristics and process requirements. The overall structural design is reasonable, highly targeted, and has outstanding mixing efficiency. Attached Figure Description

Detailed Implementation

[0015] like Figure 1-3 As shown, a multi-functional mixing tank for powder and solid particles is made of stainless steel. The mixing tank includes a tank body 1, a sealing cover 2, a stirring shaft 3, a variable frequency motor 4, and a combined stirrer 5. The bottom of the tank body 1 is set as a conical bottom, and a jacket 8 can be installed on its side wall for circulating water to achieve temperature control.

[0016] The sealing cover 2 is tightly connected to the top of the tank 1 via a flange or snap-fit ​​to ensure the equipment's airtightness. The sealing cover 2 is also equipped with an observation window 9 with a rubber sealing ring and a covered feed inlet 10. The stirring shaft 3 is driven by a variable frequency motor 4, which can be designed as a solid structure or a hollow structure for introducing media.

[0017] The combined agitator 5 is fixedly installed on the agitator shaft 3, specifically including an upper agitator assembly 51 and a lower agitator assembly 52. ​​The upper agitator assembly 51 is a high-speed shear agitator 511 with a set of serrated blades, installed at the upper end of the agitator shaft 3, corresponding to the upper-middle area of ​​the material height in the tank 1. The lower agitator assembly 52 is a low-speed, high-torque ribbon agitator 521, installed at the lower end of the agitator shaft 3, corresponding to the area near the bottom of the tank 1, and the gap between the outer edge of the ribbon of the low-speed, high-torque agitator 521 and the tank wall is small.

[0018] A discharge port 6 is connected to the center of the bottom of the barrel 1, and a sampling port 7 can be set on its side; at the same time, a detachable ultra-high molecular weight polyethylene wear-resistant liner 11 can be installed on the inner wall of the barrel 1.

[0019] The working process of the multi-functional mixing tank for mixing materials is as follows: 1. Open the feed inlet 10 of the sealing cover 2, and put the slag powder and crushed waste stone aggregate into the barrel 1 in proportion, then close the feed inlet 10 and the sealing cover 2.

[0020] 2. Start the variable frequency motor 4 and set a suitable speed. The stirring shaft 3 drives the combined agitator 5 to rotate. The speed of the stirring shaft 3 can be adjusted by the variable frequency motor 4 to meet the mixing requirements of different materials. During the mixing process, cooling or heating medium is introduced through the hollow structure of the stirring shaft 3 or the jacket 8 on the side wall of the barrel 1 to control the mixing temperature.

[0021] 3. The high-speed shear mixer 511 of the upper mixing assembly 51 rotates at high speed, generating strong shear force to quickly break up slag powder clumps, ensuring uniform powder dispersion and initial mixing with particles. The low-speed, high-torque mixer 521 of the lower mixing assembly 52 rotates at low speed; its helical structure lifts and agitates the solid particles such as waste stone aggregate at the bottom along the barrel wall, preventing coarse particles from settling and promoting further mixing of particles and powder within the barrel 1. The two mixing actions work synergistically, creating effective convection and diffusion within the barrel, achieving uniform mixing. The mixing status can be monitored through the observation window 9; once the mixture is uniformly mixed, the variable frequency motor 4 is stopped.

[0022] 4. Open the valve at discharge port 6 to discharge the mixed material. If necessary, samples can be taken for testing through sampling port 7.
