Description

Technical Field

[0001] The present invention relates to the technical field of dispersers, in particular to a circulating dispersion device and method. Background Art

[0002] The circulating dispersing device is mainly used to disperse liquid raw materials of different viscosities. The high-speed operation of the dispersing disc shears, impacts, crushes and disperses the materials to achieve the functions of rapid dispersion and refinement. The material is circulated while being dispersed, so that the material is discharged from the strong shearing area and then returns to the strong shearing area, thereby achieving repeated shearing of the material. It is an efficient equipment for dispersing solids such as coatings.

[0003] Traditional dispersers use a dispersion disc to disperse materials. The dispersion blades of the dispersion disc are fixed and difficult to adapt to changes in viscosity. The viscosity of the material is relatively high at the initial stage of dispersion, and as the dispersion device operates, the viscosity gradually decreases. The contact area between the fixed dispersion blades and the material does not change, and the shear strength cannot be reduced synchronously, which may lead to uneven dispersion caused by the mismatch between viscosity and shear strength. Summary of the Invention

[0004] The object of the present invention is to provide a circulating dispersion device and method to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A circulating dispersing device includes a base, a lifting mechanism, a dispersing mechanism, a circulating mechanism, a stirring barrel, a feed pipe and a discharge pipe. The base is fixedly connected to the lifting mechanism, the dispersing mechanism is fixedly connected to the lifting mechanism, the dispersing mechanism is rotatably connected to the stirring barrel, the stirring barrel is fixedly connected to the base, the circulating mechanism is fixedly connected to the stirring barrel, the feed pipe is fixedly connected to the stirring barrel, the discharge pipe is fixedly connected to the stirring barrel, and the discharge pipe is connected to the circulation mechanism pipeline.

[0007] The mixing barrel is fixed by the base to provide stable support for the mixing barrel and prevent vibration of the mixing barrel that affects the dispersion effect. The material to be dispersed is transported into the mixing barrel through the feed pipe, and the material in the mixing barrel is dispersed and refined by the dispersion mechanism. At the same time, the shear strength is adaptively adjusted according to the viscosity of the material to improve the dispersion efficiency. The discharge pipe and the circulation mechanism pipeline are connected to allow the material to be discharged from the strong shear zone of the dispersion mechanism and then return to the strong shear zone to achieve repeated shearing of the material, thereby improving the dispersion efficiency. The lifting mechanism allows the strong shear zone to move up and down when the dispersion mechanism is working, thereby expanding the dispersion range and improving the dispersion efficiency. After the dispersion is completed, the switch at the bottom of the discharge pipe is turned on to discharge the stirred material.

[0008] Furthermore, the dispersion mechanism includes motor No. 1, a machine base, a transmission shaft, an adjustment unit, a fixed plate, a dispersion unit and a guide block. Motor No. 1 is fixedly connected to the machine base, the machine base is fixedly connected to the lifting mechanism, the output end of motor No. 1 is fixedly connected to the transmission shaft, two fixed plates are provided, the transmission shaft is fixedly connected to the two fixed plates, the fixed plate is provided with an installation groove, several adjustment units are provided, several adjustment units are placed in the installation groove, several dispersion units are provided, several dispersion units are slidably connected to the fixed plate, and the guide block is fixedly connected to the mixing barrel.

[0009] Through the machine base, the No. 1 motor is installed on the lifting mechanism to facilitate the adjustment of the position of the No. 1 motor. It is fixed on the output end of the No. 1 motor through the transmission shaft, so that the No. 1 motor drives the transmission shaft to rotate, and the transmission shaft drives the two fixed plates fixed thereon to rotate, and the fixed plates drive several dispersion units in the installation groove to rotate. At the beginning of dispersion, the viscosity is high, the No. 1 motor has a large load and a low speed. The dispersion units are combined into large dispersion blades, which use the stronger radial thrust and shear force of the large dispersion blades to overcome the high viscosity resistance, promote the flow of materials, and quickly disperse the agglomerated materials. Subsequently, after the viscosity gradually decreases, the load of the No. 1 motor decreases and the speed returns to normal. The dispersion unit is adjusted through several adjustment units to expand the dispersion blades into multiple small dispersion blades, increase the shear edge, provide more shear areas, and avoid the dispersion blades having too little resistance at low viscosity, resulting in insufficient shear, thereby improving the refinement effect. During dispersion, the guide block guides the material in the upper dispersion area to flow to the lower dispersion area to ensure the dispersion effect.

[0010] Furthermore, the dispersion unit includes a No. 1 dispersion blade, a No. 2 dispersion blade, a No. 3 dispersion blade and a No. 1 spring. The No. 1 dispersion blade and the No. 2 dispersion blade are hingedly connected, and the No. 1 dispersion blade and the No. 3 dispersion blade are hingedly connected. There are two No. 1 springs, and the two No. 1 springs are fixedly connected to the No. 1 dispersion blade. The two No. 1 springs are fixedly connected to the fixed plate. The No. 2 dispersion blade is provided with a No. 1 guide surface, and the No. 3 dispersion blade is provided with a No. 2 guide surface.

[0011] The No. 2 dispersion blade and the No. 3 dispersion blade are respectively hinged on both sides of the No. 1 dispersion blade, and the No. 2 dispersion blade and the No. 3 dispersion blade have the same hinge axis, so that they can be combined into a large dispersion blade. The No. 2 dispersion blade is provided with a No. 1 guide surface, and the No. 3 dispersion blade is provided with a No. 2 guide surface, so that the No. 2 dispersion blade and the No. 3 dispersion blade can slide out of the installation groove at the bottom under the action of the adjustment unit, and automatically expand to both sides when pushed by the fluid, increasing the shear edge and providing more shear area, thereby improving the refinement effect. The No. 1 dispersion blade can be reset and recombined into a large dispersion blade through two No. 1 springs fixed to the bottom of the No. 1 dispersion blade.

[0012] Furthermore, the adjustment unit includes a No. 1 fixed block, a connecting rod, a No. 2 spring, a No. 2 fixed block, a guide rail and a slider. The No. 1 fixed block is fixedly connected to the fixed plate, the connecting rod and the No. 1 fixed block are hingedly connected, the No. 2 fixed block is fixedly connected to the fixed plate, the No. 2 spring is fixedly connected to the No. 1 fixed block, the No. 2 spring is fixedly connected to the No. 2 fixed block, the guide rail is fixedly connected to the fixed plate, and the slider and the guide rail are slidably connected.

[0013] It is fixed to the fixed plate through the No. 1 fixed block, and the connecting rod is hinged on the No. 1 fixed block. The two ends of the No. 2 spring are respectively fixed to the connecting rod and the No. 2 fixed block, so that when the fixed plate rotates at a slow speed, the connecting rod shrinks toward the center of the fixed plate. When the fixed plate rotates at a fast speed, the connecting rod rotates along the hinge under the influence of centrifugal force, pushing the slider to slide on the guide rail, and the slider pushes the No. 1 dispersion blade to move upward.

[0014] Furthermore, the circulation mechanism includes a sleeve, a No. 2 motor, a rotating shaft, a spiral blade, a discharging unit, a conveying pump and a speed sensor. The sleeve is connected to the discharge pipe, the No. 2 motor is fixedly connected to the sleeve, the output end of the No. 2 motor is fixedly connected to the rotating shaft, the rotating shaft and the sleeve are rotatably connected, the spiral blade is fixedly connected to the rotating shaft, the discharging unit is connected to the sleeve pipe, the conveying pump is connected to the discharge pipe pipe, the conveying pump is connected to the discharging unit pipe, and the speed sensor is fixedly connected to the mixing barrel.

[0015] The sleeve is connected to the discharge pipe, and the output end of the No. 2 motor is fixed to the rotating shaft, so that the No. 2 motor drives the rotating shaft to rotate, and the rotating shaft drives the fixed spiral blade to rotate. The upper end of the sleeve is connected to the discharge unit pipe, so that the material is transported from the discharge pipe to the discharge unit. When the viscosity of the material decreases, the speed sensor on the mixing barrel detects that the speed of the drive shaft becomes faster, and the delivery pump is started. The two ends of the delivery pump are respectively connected to the discharge pipe and the discharge unit pipe, so that part of the material is circulated through the delivery pump, thereby accelerating the circulation of the material.

[0016] Furthermore, the discharge unit includes a No. 3 fixed block and a guide plate. The No. 3 fixed block is provided with a flow groove. There are several guide plates, and the several guide plates are placed in the flow groove. The No. 3 fixed block is provided with a discharge port, and the No. 3 fixed block is provided with a feed port.

[0017] A shearing area is formed by arranging a plurality of guide plates in the flow groove of the third fixed block. By arranging another layer of guide plates on the outside of the guide plates, the outer guide plates are placed at the flow outlets of the two inner guide plates, and a shearing area is formed again at the flow outlets. For the materials in the circulation process, the flow power is utilized in conjunction with the guide plates to shear the materials, thereby achieving dispersion of the materials and improving dispersion efficiency.

[0018] Furthermore, the lifting mechanism includes a hydraulic oil station, an oil cylinder, a fixed column and a sliding rod. The hydraulic oil station and the oil cylinder are connected by pipelines. The oil cylinder and the base are fixedly connected, the fixed column and the base are fixedly connected, the sliding rod and the fixed column are slidably connected, the output end of the oil cylinder and the sliding rod are fixedly connected, and the sliding rod and the machine base are fixedly connected.

[0019] The hydraulic oil station and the cylinder pipeline are connected to make the hydraulic oil station work, and the hydraulic oil is transported or extracted to the cylinder through the pipeline, so that the output end of the cylinder can be extended and retracted, and then the output end of the cylinder pushes the slide rod to slide along the fixed column, and the slide rod drives the machine base to move, thereby adjusting the position of the shearing area.

[0020] A dispersing method of a circulating dispersing device comprises the following steps:

[0021] S1: The material to be dispersed is transported into the mixing barrel through the feed pipe;

[0022] S2: The No. 1 motor drives the transmission shaft to rotate, driving the two dispersion units on the fixed plates fixed thereon to rotate. The dispersion blades of the dispersion units perform preliminary dispersion and refinement on the material in the mixing barrel. The No. 2 motor drives the rotating shaft to rotate, which drives the fixed spiral blades to rotate, so that the material is transported from the discharge pipe to the discharge unit for circulation. The output end of the oil cylinder is extended and retracted, and the sliding rod drives the No. 2 motor to move, causing the fixed plate to move vertically, thereby adjusting the position of the shearing area, expanding the dispersion range, and thus improving the dispersion efficiency.

[0023] S3: As the dispersion process proceeds, the viscosity of the material gradually decreases, the load of motor No. 1 decreases, the speed increases, and the connecting rod rotates along the hinge under the influence of centrifugal force, pushing the slider to slide on the guide rail. The slider pushes the No. 1 dispersion blade upward, and the No. 1 dispersion blade drives the No. 2 and No. 3 dispersion blades to move upward, so that the contact area between the blades and the material increases. The No. 2 and No. 3 dispersion blades are spread to both sides under the thrust of the fluid, the shear edge increases, and more shear areas are formed. At the same time, the speed sensor detects that the speed of motor No. 1 is getting faster, and the conveying pump is started to speed up the circulation of the material, thereby achieving further dispersion and refinement of the material.

[0024] S4: The stirred material is discharged by opening the discharge pipe at the bottom.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. Through the dispersion unit of the dispersion mechanism, through the influence of viscosity on the speed of motor No. 1, the dispersion blades are combined into a large dispersion blade, or expanded into multiple small dispersion blades, and the shear strength is adaptively adjusted to ensure the matching of viscosity and shear strength, thereby ensuring the uniformity of dispersion.

[0027] 2. Through the circulation mechanism, the material is discharged from the strong shearing area of the dispersion mechanism and then returned to the strong shearing area to achieve repeated shearing of the material, thereby improving the dispersion efficiency.

[0028] 3. The lifting mechanism drives the dispersion mechanism to move up and down, thereby adjusting the position of the shearing area, expanding the dispersion range, and thus improving the dispersion efficiency.

[0029] 4. A shearing area is formed by installing several guide plates in the flow groove of the No. 3 fixed block. The flow power of the material is used in conjunction with the guide plates to shear the material, thereby achieving dispersion of the material and improving dispersion efficiency.

[0043] The mixing barrel 5 is fixed by the base 1 to provide stable support for the mixing barrel 5 to prevent the mixing barrel 5 from vibrating and affecting the dispersion effect. The material to be dispersed is transported into the mixing barrel 5 through the feeding pipe 6, and the material in the mixing barrel 5 is dispersed and refined by the dispersing mechanism 3. At the same time, the shear strength is adaptively adjusted according to the viscosity of the material to improve the dispersion efficiency. The discharge pipe 7 and the circulation mechanism 4 are connected through the pipeline so that the material is discharged from the strong shear zone of the dispersing mechanism 3 and then returned to the strong shear zone to achieve repeated shearing of the material, thereby improving the dispersion efficiency. The lifting mechanism 2 allows the strong shear zone of the dispersing mechanism 3 to move up and down when it is working, thereby expanding the dispersion range and improving the dispersion efficiency. After the dispersion is completed, the switch at the bottom of the discharge pipe 7 is turned on to discharge the stirred material.

[0044] like Figure 2 and Figure 3 As shown, the dispersion mechanism 3 includes a No. 1 motor 31, a machine base 32, a transmission shaft 33, an adjustment unit 34, a fixed plate 35, a dispersion unit 36 and a guide block 37.

The two ends of the delivery pump 46 are respectively connected to the discharge pipe 7 and the discharge unit 45 pipeline, so that a part of the material is circulated through the delivery pump 46, thereby accelerating the circulation of the material.

[0052] like Figure 9 and Figure 10 As shown, the discharge unit 45 includes a No. 3 fixed block 451 and a guide plate 452. The No. 3 fixed block 451 is provided with a flow groove 4511.

At the same time, the speed sensor detects that the speed of the No. 1 motor 31 becomes faster, and starts the conveying pump 46 to speed up the circulation of the material, thereby achieving further dispersion and refinement of the material.

At the beginning of dispersion, the viscosity is high, the No. 1 motor 31 has a large load and a low speed, and the No. 1 dispersion blade, the No. 2 dispersion blade 362 and the No. 3 dispersion blade 363 are combined into a large dispersion blade to quickly disperse the agglomerated material. The hydraulic oil is transported or extracted to the cylinder 22 through the pipeline, so that the output end of the cylinder 22 is extended and retracted, and the slide rod 24 drives the No. 2 motor 42 to move, so that the fixed plate 35 moves up and down, thereby adjusting the position of the shearing area and expanding the dispersion range. It is connected to the discharge pipe 7 through the sleeve 41, and the No. 2 motor 42 drives the rotating shaft 43 to rotate. The rotating shaft 43 drives the fixed spiral blade 44 to rotate, and is connected to the discharge unit 45 pipeline through the upper end of the sleeve 41, so that the material is transported from the discharge pipe 7 to the discharge unit 45, so that the material returns to the strong shear area, realizing repeated shearing of the material, and the viscosity gradually decreases as the dispersion proceeds. The load of motor No. 1 31 decreases, and the speed returns to normal. The connecting rod 342 rotates along the hinge, pushing the slider 346 to slide on the guide rail 345, and the slider 346 pushes the No. 1 dispersion blade 361 to move upward. The No. 2 dispersion blade 362 and the No. 3 dispersion blade 363 are respectively expanded to both sides under the thrust of the fluid, thereby increasing the shear edge and providing more shear areas, thereby improving the refinement effect. At the same time, the delivery pump 46 is started, and the delivery pump 46 is started. The two ends of the delivery pump 46 are respectively connected to the discharge pipe 7 and the discharge unit 45 pipeline, so that a part of the material is circulated through the delivery pump 46, accelerating the circulation of the material, thereby improving the dispersion efficiency.
