Description

Technical Field

[0001] This utility model belongs to the field of dispersant production technology, specifically relating to a high-efficiency dispersant mixing device. Background Technology

[0002] In the fields of chemical, lithium battery material, and dispersant production, traditional mixing equipment generally suffers from problems such as nanomaterial agglomeration, uneven mixing, and low efficiency. Conventional stirring devices rely on simple mechanical stirring, which is insufficient to overcome the strong agglomeration effect of nanoparticles, resulting in localized concentration differences (standard deviation > 15%) in the mixed material.

[0003] Existing technologies mostly employ a step-by-step processing mode, such as ultrasonic dispersion followed by mechanical mixing. This process is not only cumbersome (requiring 2-3 steps), but also prone to secondary agglomeration during the transfer process. In addition, the fixed-pitch flow guiding structure can lead to uneven distribution of fluid shear force, while ordinary filters require frequent shutdowns for cleaning due to clogging, severely impacting continuous production efficiency. To address these shortcomings, the industry needs to integrate a multi-functional device that combines filtration, mixing, and flow guiding.

[0004] This patent, through a three-stage interconnected chamber design, combined with a tapered spiral guide vane (P=Po×(1-0.03n)) and a nano-ceramic coating (Ra≤0.1μm), aims to achieve high efficiency, low consumption, and zero residue in dispersant production. Utility Model Content

The curved surface of the fixed tube is provided with several sets of stirring rods, and each set of stirring rods is fixedly connected to a scraper.

[0011] In a preferred embodiment, the pitch of the spiral guide vane gradually decreases from the inlet end to the outlet end, forming a tapered flow channel, and the pitch change of the spiral guide vane satisfies the formula: P=Po×(1-0.03n), where Po is the initial pitch at the inlet end and n is the number of spiral turns, and the surface of the spiral guide vane is provided with a nano-ceramic coating, the surface roughness of which Ra≤0.1μm.

[0012] In a preferred embodiment, gears are provided on the lower outer surface of the drive shaft, the upper outer surface of the rotating shaft, and the inner surface of the connecting belt, and they mesh with each other.

[0014] Compared with the prior art, the dispersant high-efficiency mixing device provided by this utility model has at least the following beneficial effects:

[0015] (1) Through the synergistic effect of the graded mixing chamber structure and the tapered spiral guide vanes, the material is optimized in three stages:

[0016] The inclined filter plate group (30-60°) in the filter chamber achieves pre-screening of raw materials through a gradient pore size design (the diameter of the filter pores decreases from top to bottom), reducing the energy consumption of subsequent stirring by more than 25%.

[0021] The damping ring sealing structure of the dustproof components (≥3 layers of damping rings) effectively prevents dust back-splashing, reducing the dust concentration in the working environment to 2mg / m³. 3 the following. Attached Figure Description

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Please see Figure 1-4This utility model provides a high-efficiency dispersant mixing device, comprising: a mixing tank 1, wherein the mixing tank 1 is provided with a filter chamber 101, a stirring chamber 102 and a guide chamber 103 from top to bottom, and a filter assembly 7, a stirring assembly 8 and a spiral guide vane 9 are provided in the filter chamber 101, the stirring chamber 102 and the guide chamber 103 respectively, and a drive assembly 4 is provided at the upper end of the mixing tank 1. The drive assembly 4 includes a servo motor 401, and the front end of the drive shaft 402 of the servo motor 401 is engaged with a connecting belt. Inside one end of 403, the connecting belt 403 is internally engaged with the upper end of the rotating shaft 404. The other end of the rotating shaft 404 passes through the cover plate 2 and is located in the filter chamber 101, the stirring chamber 102 and the guide chamber 103 respectively. The filter assembly 7 is slidably connected, the stirring assembly 8 is fixedly connected or the spiral guide plate 9 is fixedly connected. The lower end of the mixing tank 1 is conical and has a discharge port. The lower end of the discharge port has a discharge pipe 105. The inner curved surface of the upper end of the mixing tank 1 has a groove 104.

[0029] Further as Figure 1 and Figure 2 As shown, it is worth noting that a fixing ring 6 is fixedly connected to the middle of the curved surface of the filter chamber 101, and several fixing columns 601 are fixedly connected to the lower end of the fixing ring 6. Through the fixing ring 6 and the fixing columns 601, the structural stability of the filter assembly is enhanced, the vibration amplitude is reduced by 60%, and the screening failure caused by the displacement of the tilted filter plate is prevented.

[0030] Further as Figure 2 As shown, it is worth noting that a control valve 106 is provided on one side of the discharge pipe 105. By controlling the valve 106, the discharge flow rate can be precisely controlled (error < 3%), avoiding secondary agglomeration of the dispersant and ensuring batch consistency.

[0031] Further as Figure 3 As shown, it is worth noting that the filter assembly 7 includes a filter box 701. The curved edge of the filter box 701 has a raised guide that is slidably connected to the slot 104. The filter box 701 has an annular groove in the middle and a connection hole 702 at the lower end. The lower middle part of the filter box 701 has an inclined tube 705. Several sets of detachable filter plates 703 are installed in the annular groove. The filter plates 703 are at an angle of 30-60 degrees to the plane. Each filter plate 703 has a filter hole 704. The diameter of the filter holes 704 on the filter plate 703 decreases from top to bottom. Through the detachable filter plates 703, the gradient pore size design (decreasing by 0.5-2mm) increases the large particle interception rate to 92%. At the same time, the modular structure improves the replacement efficiency by 80%.

[0032] This solution includes the following workflow:

[0033] The working principle of this high-efficiency dispersant mixing device can be divided into a three-stage synergistic processing flow:

[0034] Preprocessing stage

[0035] The raw material enters the filter chamber 101 through the feed inlet 201 controlled by the dustproof component 5. The 30-60° inclined filter plate 703 classifies and screens the material through the gradient pore size (0.5-2mm decrease). Large particles of impurities are intercepted. The preliminarily purified raw material enters the mixing chamber 102 through the connection hole 702.

[0036] Core Hybrid Phase

[0037] The servo motor 401 drives the stirring assembly 8 through a gear meshing transmission system (drive shaft 402 / connecting belt 403 / rotating shaft 404). The stirring rod 802 efficiently mixes the materials at 1200 rpm, while the scraper 803 simultaneously scrapes off the residue on the bin wall, thereby increasing the raw material utilization rate to 98.5%.

[0038] Precision flow guiding stage

[0039] The mixed slurry enters the guide chamber 103, where the tapered spiral guide vane 9 with nano-ceramic coating (P=Po×(1-0.03n)) generates progressively stronger shear force, effectively breaking the agglomeration of nanoparticles, and finally achieves quantitative discharge through the control valve 106 of the conical discharge pipe 105;

[0040] Note: The structural stability is ensured by the fixed ring 6 and the limiting plate 4021 throughout the three-stage treatment process, and the vibration amplitude is controlled within 0.1mm.

[0041] Based on the above working process, it can be seen that: by fixing ring 6 and fixing column 601, the structural stability of the filter component is enhanced, the vibration amplitude is reduced by 60%, and screening failure caused by displacement of tilted filter plate is prevented 3. By controlling valve 106, the discharge flow rate is precisely controlled (error <3%), avoiding secondary agglomeration of dispersant and ensuring batch consistency. By using detachable filter plate 703, the gradient pore size design (0.5-2mm decrease) increases the large particle interception rate to 92%, while the modular structure improves replacement efficiency by 80%.

[0042] Further as Figure 3 As shown, it is worth noting that the stirring assembly 8 includes a fixed tube 801, which is fixedly connected to the outer surface of the middle part of the rotating shaft 404. The curved surface of the fixed tube 801 is provided with several sets of stirring rods 802. Each set of stirring rods 802 is fixedly connected to a scraper 803. The stirring rods 802 are integrated by the scraper 803, and the material mixing and wall self-cleaning are completed simultaneously, reducing the raw material residue to below 1.5%.

[0043] Further as Figure 3As shown, it is worth noting that the pitch of the spiral guide vane 9 gradually decreases from the inlet end to the outlet end, forming a tapered flow channel. The pitch change of the spiral guide vane 9 satisfies the formula: P=Po×(1-0.03n), where Po is the initial pitch at the inlet end and n is the number of spiral turns. The surface of the spiral guide vane 9 is coated with a nano-ceramic coating with a surface roughness Ra≤0.1μm. Through the tapered spiral guide vane 9, the nano-ceramic coating (Ra≤0.1μm) combined with the variable pitch design (P=Po×(1-0.03n)), the fluid shearing efficiency is improved by 40%.

[0044] Further as Figure 3 As shown, it is worth noting that gears are provided on the lower outer surface of the drive shaft 402, the upper outer surface of the rotating shaft 404, and the inner surface of the connecting belt 403, and they are meshed with each other. Furthermore, limit plates 4021 are fixedly connected to both the drive shaft 402 and the rotating shaft 404 at the upper and lower ends of the connecting belt 403. Through the gear meshing transmission system, the double limit plates 4021 ensure the transmission accuracy of the synchronous belt 403 (error ±1 rpm), and the energy consumption is reduced by 22% compared with the traditional structure.

[0045] Further as Figure 4 As shown, it is worth noting that the cover plate 2 has three feed inlets 201. Each cover plate 2 has a dustproof component 5 on one side of each feed inlet 201. Each dustproof component 5 includes a damping bolt 501 and a dustproof plate 503. Several damping rings 502 are provided at the upper end of the connection between the damping bolt 501 and the dustproof plate 503. Through the sealing structure of the damping rings 502, the three layers of damping rings control the dust leakage at the feed inlet to 1 mg / m³. 3 The following is 50% better than the industry standard.

[0046] In summary: By integrating the scraper 803 with the stirring rod 802, material mixing and wall self-cleaning are completed simultaneously, reducing raw material residue to below 1.5%. The tapered spiral guide vane 9, nano-ceramic coating (Ra≤0.1μm), and variable pitch design (P=Po×(1-0.03n)) improve fluid shear efficiency by 40%. The gear meshing transmission system and double limit plates 4021 ensure the transmission accuracy of the synchronous belt 403 (error ±1rpm), reducing energy consumption by 22% compared to traditional structures. The damping ring 502 sealing structure and three-layer damping rings control dust leakage at the inlet to 1mg / m³. 3 The following is 50% better than the industry standard.
