Description

Technical Field

[0002] The raw materials of defoamers are generally solid granular hydrophobic silica, aluminum silicate and metal soap, etc. Defoamers can also use some other types of solid granular raw materials, which provide effective defoaming and anti-foaming effects in specific systems and are particularly suitable for use in powdered, dry powder, or sustained-release applications.

[0003] In the preparation process of defoaming agents, due to the changes in the characteristics of different raw materials and process requirements, stirring equipment with different shear forces is frequently replaced. If a single shear force mixer is used and the equipment cannot be replaced or the shear force cannot be adjusted, the granular raw materials are easily attached to the mixing blades during the initial mixing, resulting in uneven stirring. It is also necessary to stop the machine regularly during stirring, scrape the wall material manually or with auxiliary equipment, and then continue emulsification to ensure that the components on the wall participate in the emulsification. This operation is more cumbersome, which will lead to poor raw material emulsification effect. Summary of the invention

[0015] 2. The operator pulls the knob to move downward, and the knob drives the hexagonal rod and the two clamping rods to move downward, and the reset spring is stretched accordingly, and the two clamping rods are disengaged from two of the clamping holes. The operator drives the hexagonal rod and the two clamping rods to rotate through the knob, and the hexagonal rod drives the hollow shaft and the bottom bevel gear to rotate, and the hexagonal rod drives the annular groove to move downward, and the annular groove drives the two locking rods to move away from each other, and the two locking springs are stretched accordingly. The ends of the two locking rods away from each other will contact the inner side of the locking ring, so that the hollow tube is locked through the contact between the locking rod and the locking ring, and the hollow shaft will not drive the hollow tube to rotate when it rotates. The rotation of the bottom bevel gear drives the side bevel gears on both sides to rotate, and the side bevel gears on both sides drive the horizontal axis and the mixing blades to rotate, so that the angle of the mixing blades can be gradually adjusted, so that the angle of the mixing blades is close to the horizontal plane perpendicular to the surface of the raw material. By gradually adjusting the angle of the mixing blades, the shear strength is gradually increased, so as to emulsify and disperse the raw materials more finely and achieve the best mixing effect.

[0016] 3. When the cam rotates, the two protrusions on the cam will gradually contact the two sliding bars, and the rotating ball will play a guiding role. The two sliding bars move away from each other, and the two sliding bars drive the sliding plates on both sides to move away from each other. The cross spring will stretch accordingly, and several movable holes will gradually stagger with several fixed holes, so that the sliding plate can block several fixed holes on the mixing blades. After blocking the fixed holes, the raw materials no longer pass through the mixing blades directly, but are forced to flow along the mixing blades, which can generate a greater pressure difference and turbulence before and after the mixing blades, further increasing the shear force, which is more conducive to refining particles or droplets and improving the mixing and emulsification effects of raw materials.

[0017] 4. When the convex block on the convex disc contacts the top bead, the top bead and the vertical rod will move downward, the vertical rod will drive the two cones to move downward, the two cones will drive the two scraper racks away from each other, the beads will play a guiding role, the support spring will be compressed accordingly, the two scraper racks will contact the inner wall of the emulsifying cylinder, the two scraper racks can effectively scrape off the raw materials on the inner wall of the emulsifying cylinder to avoid the deposition of raw materials on the inner wall of the emulsifying cylinder, thereby preventing local excessive concentration or uneven emulsification, especially during the mixing process of heating or cooling, by keeping the raw materials flowing on the wall of the emulsifying cylinder, local overheating or overcooling can be avoided, thereby further improving the effect of raw material mixing and emulsification.

[0042] The locking mechanism is also included. The locking mechanism is arranged on the emulsifying cylinder 3, the hollow tube 61 and the hexagonal rod 82. The locking mechanism is used to lock the position of the hollow tube 61. The locking mechanism includes a locking rod 91, a locking spring 92, a ball 93 and a locking ring 95. Two locking rods 91 are slidably provided at the lower part of the hollow tube 61. The two locking rods 91 are symmetrically arranged.

[0043] The side surface of the inner circle of the locking ring 95 is set as a rough surface, and the side of the two locking rods 91 away from each other is set as a rough surface.

[0044] Initially, the feed valve 41 is in an open state, and the discharge valve 42 is in a closed state. The operator adds an appropriate amount of raw materials into the emulsifying cylinder 3 through the feed valve 41, and then closes the feed valve 41. The excess air in the emulsifying cylinder 3 can be extracted through the exhaust valve 5, so that the space in the emulsifying cylinder 3 forms a vacuum. Then the operator starts the output shaft of the motor 62 to rotate, and the output shaft of the motor 62 drives the rotating shaft 63 to rotate. The rotating shaft 63 drives the hollow shaft 72, the horizontal shaft 73, the mixing blade 74, the bottom bevel gear 76 and the side bevel gear 77 to rotate through the transmission assembly 64. The mixing blade 74 rotates to mix the raw materials in the emulsifying cylinder 3. When the raw materials are initially mixed, the mixing blade 74 The angle is close to being parallel to the horizontal plane of the raw material, which can reduce the shear force, and the raw material will pass through the fixing hole 75, thereby reducing the area of ​​the raw material directly hitting the surface of the mixing blade 74, thereby further reducing the shear force, and at the same time it also helps to avoid the accumulation of raw materials on the mixing blade 74, reduce the deposition of raw materials on the mixing blade 74, and avoid the granular raw materials adhering to the mixing blade 74 to cause uneven mixing; after the initial mixing of the raw materials is completed, the operator turns off the motor 62, and when the hollow tube 61 stops rotating, the operator pulls the knob 86 to move downward, and the knob 86 drives the hexagonal rod 82 and the two clamping rods 87 to move downward, and the return spring 83 is stretched accordingly, and the two clamping rods 87 and two of them The clamping hole 88 is disengaged, and the operator drives the hexagonal rod 82 and the two clamping rods 87 to rotate through the knob 86.

The two locking springs 92 are stretched accordingly, and the ends of the two locking rods 91 away from each other will contact the inner side of the locking ring 95, so that the hollow tube 61 is locked through the contact between the locking rod 91 and the locking ring 95. When the hollow shaft 72 rotates, it will not drive the hollow tube 61 to rotate. The rotation of the bottom bevel gear 76 drives the side bevel gears 77 on both sides to rotate, and the side bevel gears 77 on both sides drive the horizontal shaft 73 The mixing blade 74 rotates with the mixing blade 74, and the angle of the mixing blade 74 can be gradually adjusted to make the angle of the mixing blade 74 close to the horizontal plane perpendicular to the surface of the raw material. By gradually adjusting the angle of the mixing blade 74, the shear strength is gradually increased, so as to emulsify and disperse the raw materials more finely and achieve the best mixing effect. After the operator releases the knob 86, under the action of the reset spring 83, the hexagonal rod 82 drives the knob 86 and the two clamping rods 87 to move upward and reset, and the two clamping rods 87 will be clamped into the other two clamping holes 88, so that the position of the hollow shaft 72 and the bottom bevel gear 76 can be fixed, and then the position of the side bevel gear 77, the horizontal shaft 73 and the mixing blade 74 can be fixed;When resetting the mixing blade 74, the operator drives the hexagonal rod 82 and the two clamping rods 87 to rotate in the opposite direction through the knob 86, and the hexagonal rod 82 drives the hollow shaft 72 and the bottom bevel gear 76 to rotate in the opposite direction, and the bottom bevel gear 76 rotates in the opposite direction to drive the side bevel gears 77 on both sides to rotate in the opposite direction, and the side bevel gears 77 on both sides drive the horizontal shaft 73 and the mixing blade 74 to rotate in the opposite direction, so that the angle of the mixing blade 74 can be gradually adjusted to make the angle of the mixing blade 74 close to the horizontal surface of the raw material; after the raw material is emulsified, the operator turns off the motor 62, and then opens the feed valve 41 and the discharge valve 42, and the emulsified raw material will be discharged from the discharge valve 42.

The cross spring 103 is stretched accordingly, and the plurality of movable holes 102 gradually stagger with the plurality of fixed holes 75, so that the sliding plate 101 can block the plurality of fixed holes 75 on the mixing blade 74. After the fixed holes 75 are blocked, the raw material no longer passes directly through the mixing blade 74. Blade 74, but is forced to flow along the mixing blade 74, which can generate a larger pressure difference and turbulence before and after the mixing blade 74, further increasing the shear force, which is more conducive to refining particles or droplets and improving the mixing and emulsification of raw materials; when the cam 106 rotates in the opposite direction, the two protrusions on the cam 106 will gradually separate from the two sliding bars 104, and under the action of the cross spring 103, the two sliding bars 104 and the sliding plates 101 on both sides move towards each other, and a number of movable holes 102 gradually overlap with a number of fixed holes 75.
