Abstract
Description
Technical Field
[0001] This application belongs to the field of storage battery production technology, and in particular relates to a colloidal mother liquor stirring device. Background Technology
[0002] Gel lead-acid batteries exhibit superior electrochemical performance and a low self-discharge rate. In actual production, the gel needs to be formulated into a gel mother liquor using fumed silica, additives, and other ingredients. This mother liquor typically needs to be stored in a storage tank for several days to form a stable gel structure, promote chemical bonding, and improve the thixotropic properties and strength of the electrolyte. However, during storage, the gel mother liquor is prone to stratification, leading to concentration differences that affect battery performance. Existing stirring equipment suffers from poor dispersion, cannot effectively solve the stratification problem, and has low stirring efficiency. Utility Model Content
[0003] To address the shortcomings of the prior art, this application provides a colloidal mother liquor stirring device, which has a better dispersion effect and can effectively solve the stratification problem.
[0004] To achieve the above objectives, the present invention employs the following technology:
[0005] A colloidal mother liquor stirring device, comprising:
[0006] The substrate has a positioning block arranged along its width in the middle, and first arc-shaped grooves are opened on both sides of the positioning block. Mounting grooves arranged along its length are opened on the substrate on both sides of the positioning block.
[0007] Two wedges are arranged in a triangle with their sides facing the positioning block. The bottom surfaces of the two wedges slide and fit into the corresponding mounting grooves along the length of the substrate. A spring is provided in the mounting groove, and the spring connects the corresponding wedge to the end of the mounting groove.
[0008] The mounting plate is parallel to the base plate and moves along its height direction. The bottom surface of the mounting plate has vertical mounting posts at both ends, and the lower end of the mounting posts is rotatably fitted with rollers that are adapted to the inclined surface of the wedge block.
[0009] Two stirring shafts are vertically mounted on the bottom of the mounting plate and located on both sides of the positioning block. Each stirring shaft is rotatable around its own axis, and stirring blades are coaxially connected to the lower end of the stirring shaft.
[0010] The beneficial effects of this utility model are as follows:
[0011] 1. By setting rollers and wedges and cooperating with springs, the downward movement of the mounting plate is converted into the synchronous movement of two wedge blocks towards the positioning block. This allows the clamping block and the positioning block to clamp and fix the storage bucket, so as to avoid displacement or shaking of the storage bucket due to the high speed of the stirring shaft, which would lead to uneven stirring and failure to effectively solve the stratification problem. This effectively improves the dispersion effect and stability of the stirring device.
[0012] 2. There are two stirring shafts, which can stir the colloidal mother liquor in two storage tanks at the same time, which helps to improve the stirring efficiency of colloidal mother liquor. Attached Figure Description

Detailed Implementation
[0019] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.
[0020] This application provides a colloidal mother liquor stirring device, such as... Figures 1-5 As shown, it includes: a base plate 1, two wedges 2, a mounting plate 3, and two stirring shafts 4, etc.
[0021] Among them, such as Figure 1 and Figure 2 As shown, a positioning block 11 is provided in the middle of the substrate 1 along its width direction. First arc-shaped grooves 12 are formed on both sides of the positioning block 11. The storage bin 5 is cylindrical. The curvature of the concave surface of the first arc-shaped groove 12 is equal to the roundness of the outer wall of the storage bin 5. When placing the storage bin 5, it can be directly inserted into the first arc-shaped groove 12, so that the concave surface of the first arc-shaped groove 12 fits against the outer wall of the storage bin 5, thereby achieving rapid positioning of the storage bin 5. Mounting grooves 13 are formed on the substrate 1 on both sides of the positioning block 11 along its length direction.
[0022] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, two wedges 2 are arranged in a triangle. The bottom surfaces of the two wedges 2 are parallel to the top surface of the substrate 1 and slide along the length of the substrate 1 in the corresponding mounting grooves 13. The sides of the wedges 2 face the positioning blocks 11. The upper end of the side of the wedges 2 protrudes towards the positioning blocks 11 to form a clamping block 21. A second arc-shaped groove 22 is provided on the side of the clamping block 21 facing the positioning blocks 11 for fitting against the outer wall of the storage barrel 5. A spring 14 is provided in the mounting groove 13 along the length of the substrate 1. The spring 14 is connected to the end of the corresponding wedge 2 and the mounting groove 13. When the spring 14 is in its natural state, the distance between the clamping block 21 and the positioning block 11 is greater than the diameter of the storage barrel 5, so as to facilitate the placement and installation of the storage barrel 5.
[0023] like Figure 1 and Figure 2 As shown, two columns 15 are vertically arranged on one side of the top surface of the substrate 1. The upper ends of the two columns 15 are connected by a connecting column 16. The two ends of the mounting plate 3 are slidably inserted through the corresponding columns 15. The mounting plate 3 is always parallel to the substrate 1. A second motor 18 is provided on the substrate 1 between the two columns 15. Its driving end is vertically upward and coaxially connected to a lead screw 17. The lead screw 17 is inserted through the mounting plate 3 and rotatably engaged with the connecting column 16. The lead screw 17 and the mounting plate 3 are threadedly engaged. The thread helix angle is less than or equal to the friction angle to ensure the self-locking property of the mounting plate 3. Correspondingly, linear cylinders, hydraulic cylinders and other mechanisms can also be used to drive the lifting and lowering of the mounting plate 3.
[0024] like Figure 1 and Figure 2 As shown, mounting posts 31 are vertically provided at both ends of the bottom surface of the mounting plate 3. The lower end of the mounting post 31 is rotatably fitted with a roller 32 that is adapted to the inclined surface of the wedge block 2. Its rotation axis is set in the width direction of the base plate 1. By moving the mounting plate 3 downward and the roller 32 sliding along the inclined surface of the wedge block 2, the wedge block 2 can be driven to move towards the positioning block 11.
[0025] like Figures 1-3As shown, two stirring shafts 4 are vertically arranged at the bottom of the mounting plate 3 and located on both sides of the positioning block 11, for entering the corresponding storage tank 5 respectively. Each stirring shaft 4 is arranged to rotate around its own axis. The lower end of the stirring shaft 4 is coaxially connected to a stirring blade 41 for stirring the colloidal mother liquor in the storage tank 5. The two stirring shafts 4 are driven by a first motor 36 located at the top of the mounting plate 3.
[0026] In application, the second motor 18 drives the lead screw 17 to raise the mounting plate 3, thereby moving the stirring blades 41 away from the base plate 1 to create space for the material storage tank 5 to be filled. The operator places the two storage tanks 5 into the two first arc-shaped grooves 12 respectively, so that the outer wall of the storage tank 5 fits against the concave surface of the first arc-shaped groove 12 to complete the positioning of the storage tanks 5. In actual production, the volume of colloidal mother liquor stored in each storage tank 5 is consistent, that is, the liquid level in each storage tank 5 is consistent. The second motor 18 drives the lead screw 17 to lower the mounting plate 3. The distance between the stirring blades 41 and the mounting plate 3 is matched with the distance between the rollers 32 and the mounting plate 3. When the mounting plate 3 lowers to the point where the outer circle of the rollers 32 is tangent to the upper end of the inclined surface of the wedge 2, the stirring blades 41 are located above the liquid surface of the colloidal mother liquor. The second motor 18 continues to drive the mounting plate 3 to lower, and the two rollers 32 abut against the inclined surface of the corresponding wedge 2, rolling from the upper end of the inclined surface to the lower end. During the rolling of roller 32, spring 14 ensures that the inclined surface of wedge 2 always abuts against roller 32. The component of the downward pressure of roller 32 on the inclined surface of wedge 2 causes both wedges 2 to move towards positioning block 11 while resisting the elastic force of spring 14. When roller 32 rolls to the lower end of the inclined surface of wedge 2, the two clamping blocks 21 abut against the corresponding storage tank 5, the concave surface of the second arc groove 22 fits against the outer wall of storage tank 5, and the two stirring blades 41 are completely inserted into the corresponding colloidal mother liquor. At this time, the second motor 18 stops driving, and the mounting plate 3 remains stationary under the self-locking action of screw 17. The first motor 36 drives the two stirring shafts 4 to rotate, thereby driving the stirring blades 41 to stir and disperse the colloidal mother liquor. After stirring is completed, mounting plate 3 rises, and wedge 2 automatically returns to its original position under the action of spring 14, so as to facilitate the removal of storage tank 5.
[0027] By using the rollers 32 and wedges 2 and cooperating with the springs 14, the downward movement of the mounting plate 3 is converted into the synchronous movement of the two wedges 2 towards the positioning block 11. This allows the clamping block 21 and the positioning block 11 to clamp and fix the storage tank 5, thus preventing displacement or shaking of the storage tank 5 due to the high speed of the stirring shaft 4, which would lead to uneven mixing and failure to effectively solve the stratification problem. This effectively improves the dispersion effect and stability of the stirring device. At the same time, since there are two stirring shafts 4, the colloidal mother liquor in the two storage tanks 5 can be stirred simultaneously, which is beneficial to improving the stirring efficiency of the colloidal mother liquor.
[0028] Specifically, such as Figures 1-3As shown, a support plate 34 is mounted parallel to the mounting plate 3 via a support plate 33. The upper end of the stirring shaft 4 passes through the mounting plate 3 and is rotatably fitted to the bottom surface of the support plate 34. A first gear 35 is coaxially fixed on the stirring shaft 4, and the first gear 35 is located between the mounting plate 3 and the support plate 34. A first motor 36 is mounted above the support plate 34, and its driving end passes vertically through the support plate 34 and is coaxially connected to a second gear 37. The second gear 37 meshes with the first gear 35, and the first motor 36 drives the second gear 37, thereby realizing the driving of the two stirring shafts 4, which helps to reduce the production cost of the stirring device.
[0029] Specifically, a disc 42 is coaxially mounted on the stirring shaft 4, located above the stirring blades 41, and fixedly connected to the mounting plate 3 via a vertical rod 43. The lower end face of the disc 42 is coaxially connected to the end face of a ring 44. Multiple guide holes 45 are opened on the ring body and arranged in an array along the circumference of the ring 44. The stirring blades 41 are located inside the ring 44. In application, the mesh-like structure formed by the disc 42 and the ring 44 serves as the stator, and the stirring blades 41 serve as the rotor. When the stirring blades 41 rotate at high speed, they draw the colloidal particles in the colloidal mother liquor into the mesh-like structure formed by the disc 42 and the ring 44. At the same time, the rotation of the stirring blades 41 generates centrifugal force, throwing the colloidal particles into the gap between the ring 44 and the stirring blades 41. Simultaneously, the ring 44 and the guide holes 45 are subjected to centrifugal compression, impact, and shearing forces, which disperse the material and continuously emulsify the colloidal particles, resulting in better dispersion and emulsification effects and further preventing the colloidal mother liquor from separating.
[0030] Preferred, such as Figure 3 As shown, the structure of the stirring blade 41 can be a double-toothed blade. Correspondingly, a feed hole 46 can be opened above the disc 42, so that the colloidal particles can be drawn in from the upper and lower ends of the mesh-like structure formed by the disc 42 and the ring 44, making the emulsification and dispersion more uniform and thorough, and effectively avoiding the separation of colloidal mother liquor.
[0031] Preferred, such as Figure 4 As shown, a pair of guide rods 19 are provided in the mounting groove 13, which are oriented towards the length of the substrate 1. The two ends of the guide rods 19 are connected to the two ends of the mounting groove 13. The bottom end of the wedge block 2 slides through the guide rods 19. The spring 14 is sleeved on the guide rods 19. The guide rods 19 have a good guiding effect on the wedge block 2, which helps to improve the reliability of the stirring device.
[0032] The above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
