Description

Technical Field

[0001] This utility model relates to the field of homogenizer technology, and in particular to a homogenizing and mixing device for polyacrylamide solution. Background Technology

[0002] Homogenization of polyacrylamide solution involves homogenizing the prepared polyacrylamide aqueous solution. Because the prepared solution often exhibits localized viscosity, layering, and clumping, homogenization with a homogenizer can break up these uneven states, allowing the molecular chains to fully expand and disperse, thus avoiding the impact of uneven concentration on the performance.

[0003] A Chinese utility model patent with publication number CN216909911U discloses an improved vacuum emulsification homogenizing mechanical stirring device, comprising a stirring frame and a rotating shaft assembly. The rotating shaft assembly includes an outer main shaft, an inner main shaft, a first stirring blade, and a second stirring blade. A third stirring blade is linked to the inner circumference of the stirring frame. Several sets of cleaning mechanisms are evenly distributed on the outer circumference of the stirring frame. Each cleaning mechanism includes a scraper and mounting components. The scraper in the homogenizer rotates synchronously with the stirring mechanism, running close to the inner wall of the homogenizing cylinder to promptly scrape off materials adhering to the cylinder wall, preventing prolonged adhesion, drying, and clumping. To reduce air bubbles adhering to the wall under vacuum conditions, the contact pressure between the scraper and the inner wall of the homogenizing cylinder in this application cannot be flexibly adjusted. It relies solely on the fixed length and rigid connection of the mounting parts to achieve contact, and the contact force cannot be adjusted according to the working conditions. In contrast, some existing homogenizers use torsion springs, rotating shafts, and other movable structures to achieve contact between the scraper and the inner wall of the homogenizing cylinder. Although these structures can adapt to the inner wall, they have a large number of gaps, dead corners, and movement gaps. The polyacrylamide solution has high viscosity and poor fluidity, and it is easy to adhere to the gaps between components. When the high-viscosity solution enters, it is difficult to drain. Long-term accumulation can easily cause clumping and deterioration, which not only affects the cleaning effect but also contaminates the material. Utility Model Content

[0004] The purpose of this invention is to provide a homogenizing mixing device for polyacrylamide solution. By using an elastic plate and a scraper, the bonding pressure can be adjusted to reduce dead corners where materials accumulate. This device is suitable for high-viscosity polyacrylamide solutions and can effectively solve the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A homogenizing and mixing device for a polyacrylamide solution includes a frame, a main controller fixedly connected to the frame, a homogenizing cylinder fixedly connected to the front of the frame, a hydraulic lifting module fixedly connected inside the frame, a first drive motor fixedly connected to the hydraulic lifting module, the first drive motor and the hydraulic lifting module being electrically connected to the main controller via wires, a cylinder head fixedly connected to the lower end of the first drive motor, a stirring shaft fixedly connected to the output end of the first drive motor extending below the cylinder head, multiple auxiliary stirring frames fixedly connected to the outside of the stirring shaft, multiple fixed seats fixedly connected to the outside of the auxiliary stirring frames, a scraper module fixedly connected between two adjacent fixed seats, the scraper module including a mounting base, an elastic plate fixedly connected to one side of the mounting base via two pressure plates, and a scraper fixedly connected to the side of the elastic plate away from the mounting base.

[0007] As a further optimization of this utility model, a bottom chamber is fixedly connected to the lower end of the homogenizing cylinder, a discharge valve is fixedly connected to the outside of the bottom chamber, a second drive motor is fixedly connected to the lower end of the bottom chamber, the second drive motor is electrically connected to the main controller through a wire, and the output end of the second drive motor extends into the bottom chamber and is fixedly connected to a homogenizing head to provide the main homogenizing conditions for the material in the homogenizing cylinder.

[0008] As a further optimization of this utility model, an elastic plate mounting groove is provided on one side of the mounting base to provide a mounting foundation for the elastic plate. Pressure plate mounting grooves are provided on both sides of the elastic plate mounting groove to provide a mounting foundation for the pressure plate. The mounting base is fixedly connected between two corresponding fixed bases.

[0009] As a further optimization of this utility model, the pressure plate is fixedly connected in the corresponding pressure plate mounting groove. Two side blocks are symmetrically fixedly connected to one of the pressure plates. Adjusting bolts are threadedly connected to the side blocks away from the pressure plate. After the two pressure plates are fixed in the corresponding pressure plate mounting grooves, the head of one side of the elastic plate can be fixed in the elastic plate mounting groove.

[0010] As a further optimization of this utility model, one end of the adjusting bolt is fixedly connected to a ball head, which is used to adjust the minimum bending angle of the elastic plate, ensuring that the scraper on one side of the elastic plate can abut against the inner wall of the homogenizing cylinder. At the same time, when the stirring shaft drives the entire fixed seat to move down into the homogenizing cylinder through the auxiliary stirring frame, it is convenient for the scraper to be inserted into the homogenizing cylinder at a preset angle in conjunction with the bottom slope, thereby ensuring that one side of the scraper can always abut against the inner wall of the homogenizing cylinder.

[0011] As a further optimization of this utility model, the elastic plate is made of fluororubber.

[0012] As a further optimization of this utility model, a support head is fixedly connected to the side of the elastic plate away from the scraper. The support head is inserted into the mounting groove of the elastic plate and fixed by two pressure plates. Two stainless steel shims are fused to the side of the elastic plate opposite to the side block. The stainless steel shims are at the same horizontal height as the corresponding adjusting bolts, and the ball head abuts against the corresponding stainless steel shims to improve the smoothness of the adjusting bolts in adjusting the elastic plate.

[0013] As a further optimization of this utility model, the scraper is made of polytetrafluoroethylene.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this invention, a combination structure of fluororubber elastic plate and polytetrafluoroethylene scraper is adopted. The bending angle of the elastic plate is controlled by adjusting bolts, so that the scraper can stably adhere to the inner wall of the homogenization cylinder, effectively solving the problem of high viscosity polyacrylamide solution sticking to the wall and clumping. In addition, the fixing method of the pressure plate and the abutment head reduces the gap between components and avoids material residue and deterioration. Attached Figure Description

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1-6 As shown, the present invention provides a homogenizing and mixing device for a polyacrylamide solution, comprising a frame 1, a main controller 2 fixedly connected to the frame 1, a homogenizing cylinder 7 fixedly connected to the front side of the frame 1, a hydraulic lifting module 3 fixedly connected inside the frame 1, a first drive motor 4 fixedly connected to the hydraulic lifting module 3, the first drive motor 4 and the hydraulic lifting module 3 being electrically connected to the main controller 2 via wires, a cylinder cover 5 fixedly connected to the lower end of the first drive motor 4, a stirring shaft 6 fixedly connected to the output end of the first drive motor 4 and extending below the cylinder cover 5, multiple auxiliary stirring frames 10 fixedly connected to the outside of the stirring shaft 6, multiple fixed seats 11 fixedly connected to the outside of the auxiliary stirring frames 10, a scraper module 12 fixedly connected between two adjacent fixed seats 11, the scraper module 12 including a mounting base 13, an elastic plate 15 fixedly connected to one side of the mounting base 13 via two pressure plates 14, and a scraper 16 fixedly connected to the side of the elastic plate 15 away from the mounting base 13.

[0025] like Figure 1 As shown, a bottom chamber 8 is fixedly connected to the lower end of the homogenizing cylinder 7, and a discharge valve 18 is fixedly connected to the outside of the bottom chamber 8. A second drive motor 9 is fixedly connected to the lower end of the bottom chamber 8. The second drive motor 9 is electrically connected to the main controller 2 through a wire. The output end of the second drive motor 9 extends into the bottom chamber 8 and is fixedly connected to a homogenizing head 17, which is used to provide the main homogenization conditions for the material in the homogenizing cylinder 7.

[0026] like Figures 3-6 As shown, a flexible plate mounting groove 19 is provided on one side of the mounting base 13 to provide a mounting base for the flexible plate 15. Pressure plate mounting grooves 20 are provided on both sides of the flexible plate mounting groove 19 to provide a mounting base for the pressure plate 14. The mounting base 13 is fixedly connected between two corresponding fixed bases 11, and the pressure plate 14 is fixedly connected within the corresponding pressure plate mounting groove 20. Two side blocks 21 are symmetrically fixedly connected to one of the pressure plates 14. Adjusting bolts 22 are threadedly connected to the side blocks 21 away from the pressure plate 14. The two pressure plates 14 are respectively fixed to the corresponding pressure plate mounting grooves. After being placed in the groove 20, the head 24 on one side of the elastic plate 15 can be fixed in the elastic plate mounting groove 19. One end of the adjusting bolt 22 is fixedly connected to the ball head 23. The ball head 23 is used to adjust the minimum bending angle of the elastic plate 15, ensuring that the scraper 16 on one side of the elastic plate 15 can abut against the inner wall of the homogenizing cylinder 7. At the same time, when the stirring shaft 6 drives the entire fixed seat 11 to move down into the homogenizing cylinder 7 through the auxiliary stirring frame 10, it is convenient for the scraper 16 to be inserted into the homogenizing cylinder 7 at a preset angle in conjunction with the bottom slope, thereby ensuring that one side of the scraper 16 can always abut against the inner wall of the homogenizing cylinder 7.

[0027] like Figure 3 As shown, the elastic plate 15 is made of fluororubber. A head 24 is fixedly connected to the side of the elastic plate 15 away from the scraper 16. The head 24 is inserted into the elastic plate mounting groove 19 and fixed by two pressure plates 14. Two stainless steel gaskets 25 are fused to the side of the elastic plate 15 opposite to the side block 21. The stainless steel gaskets 25 and the corresponding adjusting bolts 22 are at the same horizontal height, and the ball head 23 abuts against the corresponding stainless steel gasket 25 to improve the smoothness of the adjusting bolts 22 in adjusting the elastic plate 15. The scraper 16 is made of polytetrafluoroethylene.

[0028] It should be noted that this utility model is a homogenizing and mixing device for polyacrylamide solution. Before use, check the wiring and installation status of the whole machine frame 1, main controller 2, hydraulic lifting module 3, first drive motor 4, and second drive motor 9. After confirming that there is no looseness, connect the power supply and complete the device power-on self-test through the main controller 2. Then, control the hydraulic lifting module 3 to move upward through the main controller 2, raising the cylinder cover 5, stirring shaft 6, auxiliary stirring frame 10, fixed seat 11, and scraper module 12 as a whole. Add the prepared polyacrylamide solution into the homogenizing cylinder 7, and the amount of material added does not exceed the rated volume of the homogenizing cylinder 7. After the material is added, control the hydraulic lifting module 3 to move downward, so that the cylinder cover 5 and the homogenizing cylinder 7 are sealed and closed. The scraper module 12 follows the stirring shaft 6 and the auxiliary stirring frame 10 into the cylinder.

[0029] Subsequently, the first drive motor 4 is started by the main controller 2, which drives the stirring shaft 6, the auxiliary stirring frame 10 and the scraper module 12 to rotate. The adjusting bolt 22 pushes the stainless steel gasket 25 through the ball head 23, changing the bending amplitude of the elastic plate 15, so that the elastic plate 15 has elasticity. Thus, the fluororubber elastic plate 15 expands outward by its own elasticity, so that the polytetrafluoroethylene scraper 16 always adheres to the inner wall of the homogenizing cylinder 7, and the head 24 of the elastic plate 15 is firmly clamped by the pressure plate 14 without any gaps, preventing high viscosity materials from seeping in and accumulating. At the same time, the second drive motor 9 is started, which drives the homogenizing head 17 to rotate at high speed to shear and homogenize the solution. During the homogenization process, the stirring and homogenization speed can be adjusted by the main controller 2 until the solution is uniform, without layering or clumping.
