Description

Technical Field

[0001] This invention belongs to the technical field of stirring equipment, and in particular relates to a stirring device for dissolving high-viscosity polydimethyldiallylammonium chloride. Background Technology

[0002] Polydimethyl diallyl ammonium chloride is a strong cationic polyelectrolyte. It is a colorless to pale yellow viscous liquid that is soluble in water. Stirring is required to accelerate the dissolution of polydimethyl diallyl ammonium chloride in water.

[0003] In the prior art, such as the utility model patent with patent publication number CN212999845U, a stirring device for dissolving polydimethyldiallyl ammonium chloride is disclosed, which includes a stirring tank, a stirring rod and a drain pipe. The stirring tank is equipped with a stirring rod for stirring the material. The drain pipe is connected to the bottom of the stirring tank, and the material in the stirring tank is discharged through the drain pipe. Although it is equipped with a stirring rod for stirring the material, the structure of the stirring rod is simple. For the complex stirring environment of viscous polydimethyldiallyl ammonium chloride, the stirring effect of the stirring rod cannot adapt to the complex stirring environment. Summary of the Invention

[0004] Therefore, it is necessary to provide a stirring device for dissolving high-viscosity polydimethyldiallyl ammonium chloride, addressing the problem of poor stirring effect in current stirring equipment.

[0005] The above objectives are achieved through the following technical solutions:

[0006] A stirring device for dissolving high-viscosity polydimethyldiallylammonium chloride includes a stirring tank, a frame, a power unit, an isolation unit, and a stirring assembly. The stirring tank is vertically arranged and has a main chamber for storing materials. The power unit includes a cover plate, which is rotatably mounted on the frame. The isolation assembly includes a mounting column and isolation plates. The mounting column is vertically arranged and its upper end is mounted on the cover plate. Rotation of the cover plate can drive rotation of the mounting column. Two isolation plates are provided, which are radially arranged on the mounting column and are located on the same straight line. Movement of the mounting column drives movement of the isolation plates. Multiple isolation assemblies are provided and circumferentially distributed around the axis of the cover plate. Adjacent isolation assemblies are in contact with each other through the isolation plates, so that the isolation plates and the mounting columns form an isolation stirring element. The isolation stirring element has a first working state, a second working state, and a third working state. In the first working state, the isolation stirring element divides the main chamber into three parts. The system comprises two mutually isolated chambers, with the second chamber enclosing the first chamber. In a second operating state, the isolation stirring element has a first opening connecting the first and second chambers, with the first opening facing the same direction as the rotation of the cover plate, allowing material from the second chamber to enter the first chamber through the first opening. In a third operating state, the isolation stirring element has a second opening connecting the first and second chambers, with the second opening facing the opposite direction to the rotation of the cover plate, allowing material from the first chamber to enter the second chamber through the second opening. A stirring assembly is disposed in the first chamber for stirring the material, with the stirring assembly stirring the material in the same direction as the rotation of the cover plate. The mounting columns can slide radially along the cover plate, disengaging the isolation plates on some adjacent mounting columns, thereby allowing the isolation stirring element to switch between the first, second, or third operating states.

[0007] Furthermore, a protrusion is provided at the upper end of the mounting column, and a first slide rail is provided on the cover plate. The protrusion and the first slide rail are slidably engaged, thereby allowing the mounting column to slide relative to the cover plate. The first slide rail is arranged along the radial direction of the cover plate, thereby allowing the mounting column to slide along the radial direction of the cover plate. The power assembly includes a hinge rod, which is arranged along the radial direction of the cover plate. One end of the hinge rod is hinged to the protrusion, and the other end of the hinge rod can move up and down to drive the protrusion to slide on the first slide rail. The sliding of the protrusion on the first slide rail drives the mounting column to move radially along the cover plate, thereby switching the working state of the isolation stirring element. The isolation stirring element has a first end and a fourth end, which are sequentially the fourth end along the rotation direction of the cover plate. The first end and the fourth end are adjacent to each other. The hinge rod on the mounting post at the first end and the hinge rod on the mounting post at the fourth end are respectively set above and below the cover plate. By moving the hinge rods on the first end and the fourth end up and down, the isolation plate on the first end and the isolation plate on the fourth end are disengaged, thereby opening the first opening or the second opening on the isolation stirring member. When the hinge rods on the first end and the fourth end move down, the isolation stirring member has the first opening and is in the second working state. When the hinge rods on the first end and the fourth end move up, the isolation stirring member has the second opening and is in the third working state.

[0008] Furthermore, the power assembly also includes a first telescopic rod and a second telescopic rod capable of extension and retraction; the first telescopic rod is mounted at the axis below the cover plate, and the second telescopic rod is mounted at the axis above the cover plate; a hinge rod at the first end is hinged to the first telescopic rod; a hinge rod at the second end is hinged to the second telescopic rod; when the first telescopic rod extends downward and the second telescopic rod retracts downward, the isolation stirring element is in a second working state; when the first telescopic rod retracts upward and the second telescopic rod extends upward, the isolation stirring element is in a third working state.

[0009] Furthermore, the isolation stirring component also has a second end and a third end, which are adjacent to each other and, along the rotation direction of the cover plate, are sequentially the first end, the second end, the third end, and the fourth end; along the rotation direction of the cover plate, the hinge rods on the first end to the second end are hinged to the first telescopic rod, and the height of the hinge point increases sequentially; along the rotation direction of the cover plate, the hinge rods on the third end to the fourth end are hinged to the second telescopic rod, and the height of the junction point increases sequentially.

[0010] Furthermore, a second slide rail is provided on the mounting column, and the second slide rail is arranged in the radial direction of the mounting column; the isolation plate is slidably installed on the second slide rail, so that the isolation plate can move relative to the radial direction of the mounting column; the isolation assembly also includes a traction unit, which can make the isolation plates between adjacent mounting columns contact each other when the isolation agitator is in the first working state.

[0011] Furthermore, the traction unit includes a first elastic element, which is disposed in the second slide and is capable of applying a force to the isolation plate, so that the isolation plate can extend out of the second slide or has a tendency to extend out of the second slide.

[0012] Furthermore, the traction unit includes a second elastic element, a wedge block, and a guide frame; the guide frame has a fixed part and a wedge part, the fixed part is perpendicularly fixed to the wedge part, the fixed part is fixed to the lower surface of the cover plate, the wedge block is fixed to the upper end of the isolation plate, the wedge block and the wedge part have inclined surfaces with a guiding function, the isolation plate abuts against the wedge part of the guide frame through the wedge block, when the mounting column moves away from the cover plate, the wedge part applies a force to the isolation plate through the wedge block to move the isolation plate away from the mounting column; the second elastic element is disposed in the second slide rail, which can apply a force to the isolation plate to move the isolation plate towards the axis of the mounting column, and keep the wedge block and the wedge part abutting; when the hinge rod drives the mounting column closer to the cover plate, the second elastic element moves the isolation plate towards the axis of the mounting column; when the hinge rod drives the mounting column away from the cover plate, the wedge part moves the isolation plate away from the axis of the mounting column through the wedge block.

[0013] Furthermore, the isolation assembly also includes a first telescopic rod and a second telescopic rod; the first telescopic rod and the second telescopic rod are annular cylinder structures with a rotating through hole in the middle, and a mating through hole is provided along the axis of the cover plate; the rotating through hole and the mating through hole are coaxially arranged; the stirring assembly includes a rotating shaft and a stirring part; the rotating shaft is vertically arranged and one end is rotatably mounted on the frame, and the other end of the rotating shaft passes through the mating through hole and the rotating through hole; the stirring part is arranged in the first compartment and mounted on the rotating shaft, and the rotation of the rotating shaft drives the stirring part to rotate, so that the stirring part stirs the first compartment.

[0014] Furthermore, the first telescopic rod includes an annular hydraulic cylinder and an annular push rod; the annular push rod and the annular hydraulic cylinder are in sliding sealing cooperation, the hinge rod is hinged to the side wall of the annular push rod, and the annular hydraulic cylinder is fixed to the cover plate; the first telescopic rod and the second telescopic rod have the same structure.

[0015] Furthermore, the frame can be raised and lowered, and the raising and lowering of the frame drives the raising and lowering of the power unit, isolation unit and mixing unit.

[0016] The beneficial effects of this invention are:

[0017] 1. An isolation mixing component is formed by the installation column and the isolation plate. The isolation mixing component divides the main chamber into a first sub-chamber and a second sub-chamber, so that the mixing component can fully mix the material in the first sub-chamber. By switching different working states by the isolation mixing component, the material can be exchanged between the first sub-chamber and the second sub-chamber, so that the material in the main chamber can be fully mixed.

[0018] 2. By setting up a traction unit, the isolation plates from the first end to the second end are always in contact with each other, and the isolation plates from the third end to the fourth end are always in contact with each other, so that the isolation stirring element forms a continuous inclined guiding surface, thereby promoting the flow of materials in the first chamber and the second chamber.

[0043] The following reference Figures 1 to 12 This invention describes a stirring device for dissolving high-viscosity polydimethyldiallylammonium chloride, provided in an embodiment of the invention.

[0044] A stirring device for dissolving high-viscosity polydimethyldiallyl ammonium chloride includes a stirring tank 200 for storing materials, a frame 100, a power assembly, an isolation assembly, and a stirring assembly. The stirring tank 200 is vertically arranged and has a main chamber 210 for storing materials inside. The power assembly includes a cover plate 300, which is rotatably mounted on the frame 100 and located above the stirring tank 200. The isolation assembly includes a mounting column 420 and an isolation plate 410. The mounting column 420 is vertically arranged and its upper end is mounted on the cover plate 300, so that the rotation of the cover plate 300 can drive the rotation of the mounting column 420. Two isolation plates 410 are provided, and the two isolation plates 410 are radially arranged on the mounting post 420 and are located on the same plane. The movement of the mounting post 420 drives the isolation plates 410 to move. Multiple isolation components are provided and distributed circumferentially around the axis of the cover plate 300. Adjacent isolation components are in contact with each other through isolation plates 410, so that the multiple sets of isolation plates 410 and the mounting post 420 form an isolation stirring component 400. The isolation stirring component 400 has a first working state, a second working state, and a third working state. In the first working state, the isolation stirring component 400... The main chamber 210 is divided into a first sub-chamber 220 and a second sub-chamber 230, which are isolated from each other. The second sub-chamber 230 surrounds the first sub-chamber 220. In the second working state, the isolating agitator 400 has a first opening 500, which connects the first sub-chamber 220 and the second sub-chamber 230. The orientation of the first opening 500 is the same as the rotation direction of the cover plate 300, allowing the material in the second sub-chamber 230 to enter the first sub-chamber 220 through the first opening 500. In the third working state, the isolating agitator 400 has a second opening 510, which connects the first sub-chamber 220 and the second sub-chamber 230. The second chamber 230 is connected, and the orientation of the second opening 510 is opposite to the rotation direction of the cover plate 300, so that the material in the first chamber 220 enters the second chamber 230 through the second opening 510; the stirring assembly is set in the first chamber 220 for stirring the material, and the stirring assembly stirs the material in the same direction as the rotation direction of the cover plate 300; the mounting column 420 can slide radially along the cover plate 300, so that the isolation plates 410 on some adjacent mounting columns 420 are disengaged, so that the isolation stirring component 400 can be switched to the first working state, the second working state, or the third working state.

[0045] Specifically, the mixing tank 200 is vertically arranged with an open top and a sealed bottom. During use, materials are added to the main chamber 210 through the upper opening of the mixing tank 200. The cover plate 300 can rotate around its own axis. A first drive motor is provided on the frame 100, which can drive the cover plate 300 to rotate. The rotation of the cover plate 300 drives the mounting column 420 to rotate around the axis of the cover plate 300, and the rotation of the mounting column 420 drives the isolation plate 410 to rotate.

[0046] The isolation stirring element 400 consists of multiple mounting columns 420 and isolation plates 410. Adjacent mounting columns 420 are in contact with each other through the isolation plates 410, forming a continuous plate-like structure. In the first working state, the isolation stirring element 400 is a continuous annular plate, dividing the main chamber 210 into a first sub-chamber 220 and a second sub-chamber 230. The mounting columns 420 move radially along the cover plate 300, causing relative movement between the mounting columns 420, thereby causing the isolation plates 410 between the mounting columns 420 to disengage. This causes the continuous plate-like structure of the isolation stirring element 400 to form a spiral plate-like structure with an opening. When the spiral plate-like structure rotates in the same direction as the cover plate 300, the opening is the first opening 500. When the spiral plate-like structure rotates in the opposite direction to the cover plate 300, the opening is the second opening 510. It can be understood that the rotation direction of the isolation stirring element 400 is related to the movement direction of the mounting columns 420. The rotation of the cover plate 300 drives the rotation of the isolation stirring component 400, while the stirring assembly stirs within the first chamber 220. The rotation direction of the isolation stirring component 400 is the direction in which its spiral plate-like structure extends from the inside to the outside when viewed from above.

[0047] The duration of the isolation stirring component 400 in the first working state is a first preset time, the duration of the second working state is a second preset time, and the duration of the third working state is a third preset time.

[0048] Initially, the isolation agitator 400 is in the first working state. Subsequently, the isolation agitator 400 switches to the third working state, the first working state, and the second working state in sequence, and cycles in sequence. The isolation agitator 400 remains in the corresponding working state for the corresponding preset time.

[0049] It is understandable that when the isolation agitator 400 is in the second working state, the material in the second chamber 230 enters the first chamber 220. This is not a strictly unidirectional flow of material, but rather an exchange of materials between the first chamber 220 and the second chamber 230. However, under the action of the isolation agitator 400, the amount of material entering the first chamber 220 from the second chamber 230 is greater than the amount of material entering the second chamber 230 from the first chamber 220. The same applies in the third working state.

[0050] The first preset time, the second preset application time, and the third preset time are set according to the actual needs of the project.

[0051] The mounting column 420 and the partition plate 410 divide the main chamber 210 into a first sub-chamber 220 and a second sub-chamber 230, so that the stirring assembly can fully stir the material in the first sub-chamber 220. The cover plate 300 drives the mounting column 420 and the partition plate 410 to rotate, so that the material in the first sub-chamber 220 and the second sub-chamber 230 can be exchanged, so that the material in the main chamber 210 can be fully stirred.

[0052] The mounting post 420 has a protrusion 330 at its upper end, and the cover plate 300 has a first slide rail 310. The protrusion 330 and the first slide rail 310 are slidably engaged, allowing the mounting post 420 to slide relative to the cover plate 300. The first slide rail 310 is arranged along the radial direction of the cover plate 300, allowing the mounting post 420 to slide radially along the cover plate 300. The power assembly includes a hinge rod 320, which is arranged along the radial direction of the cover plate 300. One end of the 0 is hinged to the protrusion 330, and the other end of the hinge rod 320 can move up and down to drive the protrusion 330 to slide on the first slide rail 310. The sliding of the protrusion 330 on the first slide rail 310 drives the mounting column 420 to move radially along the cover plate 300, so that the isolation stirring element 400 switches its working state. The isolation stirring element 400 has a first end 520 and a fourth end 550, which are the fourth end 550 and the first end 550 in sequence along the rotation direction of the cover plate 300. 520, the first end 520 and the fourth end 550 are adjacent, and the hinge rod 320 on the mounting post 420 of the first end 520 and the hinge rod 320 on the mounting post 420 of the fourth end 550 are respectively set above and below the cover plate 300; by moving the hinge rod 320 on the first end 520 and the fourth end 550 up and down, the isolation plate 410 on the first end 520 and the isolation plate 410 on the fourth end 550 are disengaged, thereby opening the first opening 500 or the second opening 510 on the isolation stirring member 400; when the hinge rod 320 on the first end 520 and the fourth end 550 moves down, the isolation stirring member 400 has the first opening 500, and the isolation stirring member 400 is in the second working state; the isolation plate 410 on the first end 520 and the isolation plate 410 on the fourth end 550 form a guiding slope, so that the material in the second chamber 230 enters the first chamber 220.

[0053] When the hinge rod 320 located on the first end 520 and the fourth end 550 moves upward, the isolation stirring member 400 has a second opening 510, and the isolation stirring member 400 is in a third working state; the isolation plate 410 on the first end 520 and the isolation plate 410 on the fourth end 550 form a guiding slope, so that the material in the first chamber 220 enters the second chamber 230.

[0054] The power assembly also includes a telescopic first telescopic rod 600 and a telescopic second telescopic rod 610; the first telescopic rod 600 is mounted at the axis below the cover plate 300, and the second telescopic rod 610 is mounted at the axis above the cover plate 300; a hinge rod 320 located at the first end 520 is hinged to the first telescopic rod 600; a hinge rod 320 located at the second end 530 is hinged to the second telescopic rod 610; when the first telescopic rod 600 extends downward and the second telescopic rod 610 retracts downward, the isolation stirring element 400 is in a second working state; when the first telescopic rod 600 retracts upward and the second telescopic rod 610 extends upward, the isolation stirring element 400 is in a third working state.

[0055] Specifically, the protrusion 330 located at the fourth end 550 passes through the first slide rail 310, causing the second telescopic rod 610 to drive the mounting post 420 on the fourth end 550 to move.

[0056] The isolation stirring element 400 also has a second end 530 and a third end 540, which are adjacent to each other. Along the rotation direction of the cover plate 300, they are sequentially the first end 520, the second end 530, the third end 540, and the fourth end 550. Along the rotation direction of the cover plate 300, the hinge rods 320 on the first end 520 to the second end 530 are hinged to the first telescopic rod 600, and the height of the hinge points increases sequentially. This causes the travel distance of the mounting post 420 on the second end 530 to the first end 520 to increase sequentially per unit time. After the first telescopic rod 600 extends or retracts by a unit length, the travel distance of the mounting post 420 on the first end 520 is greater than that of the mounting post 420 on the second end 530. When the first telescopic rod 600 extends or retracts, the travel distance of the mounting post 420 on the first end 520 to the second end 530 decreases, thereby forming a guide slope on the first end 520 to the second end 530 of the isolation stirring element 400.

[0057] Along the rotation direction of the cover plate 300, the hinge rod 320 on the third end 540 to the fourth end 550 is hinged to the second telescopic rod 610, and the height of the hinge point increases sequentially; so that the moving stroke of the mounting column 420 on the fourth end 550 to the third end 540 increases sequentially per unit time. When the second telescopic rod 610 extends or retracts, it can form a guide slope on the third end 540 to the fourth end 550 of the isolation stirring member 400.

[0058] Specifically, along the rotation direction of the cover plate 300, the protrusions 330 at the third end 540 to the fourth end 550 pass through the first slide rail 310 on the cover plate 300, so that the second telescopic rod 610 extends and retracts, driving the mounting post 420 on the first end 520 to the second end 530 to move.

[0059] Initially, the isolation stirring element 400 is a closed annular structure, and the isolation plates 410 on the isolation stirring element 400 are in contact with each other, so that the first chamber 220 and the second chamber 230 are isolated from each other.

[0060] The first telescopic rod 600 extends downward, causing the mounting posts 420 on the first end 520 to the second end 530 of the isolation stirring member 400 to move radially towards the axis of the cover plate 300; the second telescopic rod 610 shortens downward, causing the mounting posts 420 on the third end 540 to the fourth end 550 of the isolation stirring member 400 to move radially away from the axis of the cover plate 300; thereby causing the isolation plate 410 at the first end 520 to disengage from the isolation plate 410 at the fourth end 550 and form the first opening 500, such as... Figure 4 As shown, the orientation of the first opening 500 is the same as the rotation direction of the cover plate 300, and the rotation direction of the isolation stirring element 400 is the same as the rotation direction of the cover plate 300.

[0061] The first telescopic rod 600 shortens upwards, and the second telescopic rod 610 extends upwards, causing the mounting column 420 to move on the first slide rail 310 of the cover plate 300. Figure 6 As shown, a second opening 510 is formed on the isolation stirring member 400, the orientation of the second opening 510 is opposite to the rotation direction of the cover plate 300, and the rotation direction of the isolation stirring member 400 is opposite to the rotation direction of the cover plate 300.

[0062] A second slide rail 430 is provided on the mounting column 420, and the second slide rail 430 is arranged in the radial direction of the mounting column 420; the isolation plate 410 is slidably mounted on the second slide rail 430, so that the isolation plate 410 can move relative to the mounting column 420 in the radial direction; the isolation assembly also includes a traction unit, which can make the isolation plates 410 between adjacent mounting columns 420 contact each other when the isolation stirring member 400 is in the first working state.

[0063] In one embodiment, a mounting post 420 is provided between the second end 530 and the third end 540. This mounting post 420 is fixed relative to the cover plate 300, so that the first chamber 220 and the second chamber 230 are connected only through the first opening 500 or the second opening 510, so that the material in the first chamber 220 can flow into the second chamber 230 only after being fully stirred by the stirring assembly.

[0064] The traction unit includes a second elastic element, a wedge block 700, and a guide frame 710. The guide frame 710 has a fixing part 720 and a wedge part 730. The fixing part 720 and the wedge part 730 are perpendicularly fixed to each other and are fixed to the lower surface of the cover plate 300.

The isolation plate 410 abuts against the wedge part 730 of the guide frame 710 through the wedge block 700. When the mounting post 420 moves away from the cover plate 300, the wedge part 730 applies a force to the isolation plate 410 through the wedge block 700, causing the isolation plate to... 410 moves away from the mounting post 420; the second elastic element is disposed in the second slide rail 430, which can apply force to the isolation plate 410, causing the isolation plate 410 to move towards the axis of the mounting post 420, and causing the wedge block 700 to remain in contact with the wedge portion 730; when the hinge rod 320 drives the mounting post 420 to move closer to the cover plate 300, the second elastic element causes the isolation plate 410 to move towards the axis of the mounting post 420; when the hinge rod 320 drives the mounting post 420 to move away from the cover plate 300, the wedge portion 730 causes the isolation plate 410 to move away from the axis of the mounting post 420 through the wedge block 700.

[0065] By setting up a traction unit, the isolation plates 410 from the first end 520 to the second end 530 are always in contact with each other, and the isolation plates 410 from the third end 540 to the fourth end 550 are always in contact with each other, so that the isolation stirring member 400 forms a continuous guiding surface, thereby promoting the flow of materials in the first chamber 220 and the second chamber 230.

[0066] The first telescopic rod 600 and the second telescopic rod 610 are annular cylinder structures with a rotating through hole in the middle, and a mating through hole is provided along the axis of the cover plate 300; the rotating through hole and the mating through hole are coaxially arranged; the stirring assembly includes a rotating shaft 800 and a stirring part 810; the rotating shaft 800 is vertically arranged and one end is rotatably mounted on the frame 100, and the other end of the rotating shaft 800 passes through the mating through hole and the rotating through hole; the stirring part 810 is arranged in the first sub-chamber 220 and is mounted on the rotating shaft 800.

[0067] Specifically, the stirring assembly also includes a second drive motor, which is fixed to the frame 100 and its output end is connected to the rotating shaft 800. The rotation of the second drive motor drives the rotating shaft 800 to rotate. The stirring section 810 has multiple stirring blades, which are evenly distributed around the axis of the rotating shaft 800. Multiple stirring sections 810 are provided and arranged vertically along the axis of the rotating shaft 800.

The extension and retraction of the telescopic cylinder 110 can drive the sliding plate 130 to slide on the fixed rod 120, so that the sliding plate 130 rises and falls. When the material in the mixing tank 200 is stirred, the telescopic cylinder 110 is activated, so that the telescopic cylinder 110 extends. The extension of the telescopic cylinder 110 drives the sliding plate 130 to rise. The rise of the sliding plate 130 drives the power component, the isolation component, and the mixing component to rise and move out of the main chamber 210.

The second drive motor is driven, and the rotation of the second drive motor drives the rotating shaft 800 to rotate. The rotation of the rotating shaft 800 drives the stirring part 810 to rotate and stir the material in the first compartment 220.

[0074] Specifically, when the mounting post 420 moves and approaches the axis of the cover plate 300, the isolation plates 410 on different mounting posts 420 press against each other, causing the isolation plates 410 to move toward the axis of the mounting post 420; when the mounting post 420 moves away from the axis of the cover plate 300, the first elastic element applies a force to the isolation plates 410, causing the isolation plates 410 to move away from the axis of the mounting post 420.
