Abstract
Description
Technical Field
[0001] This utility model relates to the field of potassium persulfate composite powder processing technology, and in particular to a potassium persulfate composite powder premixing mechanism. Background Technology
[0002] Potassium persulfate complex powder is prepared by mixing potassium persulfate and a carrier material in a certain ratio. The carrier material can effectively improve the storage stability of the potassium persulfate complex. The preparation of potassium persulfate complex powder requires a mixing device; however, some existing mixing devices cause clumping residue in the mixing tank after preparation.
[0003] To address the aforementioned technical problems, prior art patent application 202320382778.8 discloses a closed mixing device for producing potassium persulfate compound powder. This device uses a stirring rack and stirring rod to stir the powder, ensuring more thorough mixing. Layered plates exchange and mix powder from different locations, improving mixing uniformity. However, in this prior art, the potassium persulfate compound powder experiences relatively violent collisions with the stirring rod during stirring, easily leading to particle breakage and loose bonding of the compound. Utility Model Content
[0004] In view of this, the purpose of this utility model is to propose a premixing mechanism for potassium persulfate composite powder, so as to solve the problem that the potassium persulfate composite powder will have a relatively violent collision with the stirring rod during stirring, which will easily cause the composite particles to be crushed and not tightly bound.
[0005] To achieve the above objectives, this utility model provides a potassium peroxymonosulfate composite powder premixing mechanism, including a support base, and the potassium peroxymonosulfate composite powder premixing mechanism further includes:
[0006] Rotate the rocker arm mounted on the support base.
[0007] Rotate the mixing tank located inside the cradle.
[0008] The drive unit used to drive the mixing tank to rotate.
[0009] Several spiral blades are uniformly fixed inside the mixing tank in a circumferential direction, and a mixing area is formed between two adjacent spiral blades.
[0010] Side bars fixed on the boundary of the spiral blade.
[0011] A central shaft that rotates axially inside the mixing tank.
[0012] Three diverter plates are uniformly fixed around the outside of the central axis. After the raw material particles roll onto one of the diverter plates, the central axis is subjected to uneven force and deflects, scattering the raw material into different mixing areas.
[0013] Preferably, the potassium persulfate composite powder premixing mechanism further includes:
[0014] A reciprocating drive is used to drive the rocker arm and the mixing tank to reciprocate in the axial direction of the mixing tank. Under the drive of the reciprocating drive, the two end faces of the mixing tank are reversed up and down.
[0015] Preferably, the deflection axis of the cradle intersects and is perpendicular to the axis of the mixing tank in the horizontal plane.
[0016] Preferably, the potassium persulfate composite powder premixing mechanism further includes:
[0017] A support column is fixedly mounted on the cradle, and one end of the support column is rotatably connected to the end face of the mixing tank away from the filling port.
[0018] Preferably, the potassium persulfate composite powder premixing mechanism further includes:
[0019] The can lid is used to seal the filling port of the mixing tank. The inner end face of the can lid is provided with a recessed groove. When the can lid seals the filling port of the mixing tank, one end of the central shaft is inserted into the recessed groove.
[0020] Preferably, the overall twisting direction of the side strip is consistent with the helical twisting direction of the spiral blade, and the included angle between the surfaces of the side strip and the spiral blade is greater than or equal to ° and less than °.
[0021] Preferably, the reciprocating drive includes a rocker arm radially fixed to the outside of the rotating shaft on the rocker arm, the rocker arm having a guide groove, a turntable rotatably mounted on the support base, a sliding column fixed on the turntable, one end of the sliding column being slidably sleeved inside the guide groove, and a drive motor for driving the turntable to rotate on the support base.
[0022] Preferably, the driving unit includes a gear ring fixedly sleeved on the outside of the mixing tank and a transmission gear rotatably fitted inside the rocker arm. The tooth surface of the transmission gear meshes with the tooth surface of the gear ring. A servo motor is used to drive the transmission gear to rotate. A guide wheel is rotatably provided inside the rocker arm, and the guide wheel abuts against the outside of the mixing tank.
[0023] The beneficial effects of this utility model are:
[0024] This invention utilizes spiral blades and three rotatable diverter plates evenly arranged circumferentially within the mixing tank. After the raw materials are added and the tank lid is tightened, the mixing tank rotates under the drive of the drive unit, and the rocker arm deflects back and forth along the axial direction of the mixing tank under the drive of the reciprocating drive component. This allows the raw materials to flow, tumble, and mix within the mixing tank, greatly reducing the degree of collision and vibration during the mixing process, improving the mixing effect, and allowing the raw materials to flow more gently onto the diverter plates. This causes uneven force on the central axis, resulting in deflection and irregularly dispersing the raw materials into different mixing areas, thus improving the uniformity of the raw material mixing.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect.

[0035] like Figures 1 to 5 As shown, a potassium persulfate composite powder premixing mechanism includes a support base 1, and further includes:
[0036] Rotate the rocker arm 2 mounted on the support base 1.
[0037] Rotate the mixing tank 4 located inside the rocker arm 2.
[0038] Drive unit 5 for driving the rotation of mixing tank 4.
[0039] Several spiral blades 6 are uniformly fixed inside the mixing tank 4 in a circumferential direction. The mixing area is formed between two adjacent spiral blades 6. During the rotation of the mixing tank 4, the raw material particles will flow and roll along the surface of the spiral blades 6 in multiple mixing areas below the axis of the mixing tank 4. After the raw material particles are driven to rise to a certain height in the mixing area, most of the raw material particles will fall into the adjacent mixing area at a lower position. This process is repeated to uniformly mix the raw material particles and reduce the collision force and vibration of the raw materials during the mixing process, thereby improving the mixing effect of potassium persulfate complex powder.
[0040] The side baffle 9 is fixed on the boundary of the spiral blade 6. The side baffle 9 can extend the time that the raw material particles stay in a mixing area during the rotation of the mixing tank 4. It can also improve the mixing uniformity of the raw material particles when they move back and forth between the mixing areas.
[0041] A central shaft 10 is axially rotatable within the mixing tank 4.
[0042] Three diverter plates 11 are uniformly fixed around the outside of the central shaft 10. After the raw material particles roll onto one of the diverter plates 11, the central shaft 10 is subjected to uneven force and deflects, spreading the raw material into different mixing areas. This can further improve the uniform mixing efficiency of the raw material particles.
[0043] like Figures 3 to 5 As shown, the potassium persulfate composite powder premixing mechanism also includes:
[0044] The reciprocating drive 3 is used to drive the rocker arm 2 and the mixing tank 4 to reciprocate in the axial direction of the mixing tank 4. Under the drive of the reciprocating drive 3, the two end faces of the mixing tank 4 are reversed up and down. Combined with the self-rotation of the mixing tank 4, the efficiency of uniform mixing of raw material particles is further improved.
[0045] like Figures 1 to 5 As shown, the deflection axis of the rocker arm 2 intersects and is perpendicular to the axis of the mixing tank 4 in the horizontal plane. This allows the mixing tank 4 to deflect with the reciprocating motion of the rocker arm 2 while it rotates, causing the two end faces of the mixing tank 4 to alternately flip up and down, thereby improving the mixing effect of the raw material particles flowing and tumbling.
[0046] like Figure 2 As shown, the potassium persulfate composite powder premixing mechanism also includes:
[0047] A support column 8 is fixedly mounted on the rocker arm 2, and one end of the support column 8 is rotatably connected to the end face of the mixing tank 4 away from the filling port.
[0048] like Figures 1 to 4 As shown, the potassium persulfate composite powder premixing mechanism also includes:
[0049] The can cover 7 is used to seal the filling port of the mixing tank 4. The inner end face of the can cover 7 is provided with a recessed groove. When the can cover 7 seals the filling port of the mixing tank 4, one end of the central shaft 10 is inserted into the recessed groove. This design is to support the central shaft 10 when the mixing tank 4 shakes to mix the raw materials, thereby improving its structural strength. When some raw materials roll onto one of the flow dividers 11, the central shaft 10 will be subjected to uneven force and deflected, so that the raw materials falling on the flow dividers 11 can be distributed to multiple mixing areas, thereby further improving the uniformity of mixing and improving the mixing efficiency.
[0050] like Figure 3 and Figure 5 As shown, the overall twisting direction of the side baffle 9 is consistent with the spiral twisting direction of the spiral blade 6, and the included angle between the surface of the side baffle 9 and the spiral blade 6 is greater than or equal to 90° and less than 135°. This design can extend the time that the raw material particles remain in a mixing area during the rotation of the mixing tank 4, and can improve the mixing uniformity of the raw material particles when they move back and forth between the various mixing areas.
[0051] like Figures 3 to 5As shown, the reciprocating drive component 3 includes a rocker arm 31 radially fixed to the outside of the rotating shaft on the rocker arm 2. The rocker arm 31 is provided with a guide groove 32. A turntable 33 is rotatably provided on the support base 1. A sliding column 35 is fixed on the turntable 33. One end of the sliding column 35 is slidably sleeved inside the guide groove 32. A drive motor 34 is provided on the support base 1 for driving the turntable 33 to rotate. The drive motor 34 drives the turntable 33 to rotate. The turntable 33 drives the sliding column 35 to rotate, so that the sliding column 35 slides up and down inside the guide groove 32, thereby driving the rocker arm 31 to reciprocate within a certain angle, so that the rocker arm 2 and the mixing tank 4 shake synchronously, so that the two end faces of the mixing tank 4 are reversed up and down.
[0052] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the drive unit 5 includes a gear ring fixedly sleeved on the outside of the mixing tank 4 and a transmission gear rotatably fitted inside the rocker arm 2. The tooth surface of the transmission gear meshes with the tooth surface of the gear ring. A servo motor is used to drive the transmission gear to rotate. A guide wheel is rotatably provided inside the rocker arm 2, and the guide wheel abuts against the outside of the mixing tank 4.
[0053] Working principle: After the raw materials to be mixed are added into the mixing tank 4 through the inlet, the tank cover 7 is tightened, and then the servo motor is started. It will drive the mixing tank 4 to rotate. The raw material particles will flow and roll along the surface of the spiral blade 6 in multiple mixing areas below the axis of the mixing tank 4. After the raw material particles are driven to rise to a certain height in the mixing area, most of the raw material particles will fall into the adjacent mixing area at a lower position. This process is repeated to uniformly mix the raw material particles and reduce the collision force and vibration of the raw materials during the mixing process, thereby improving the mixing effect of potassium persulfate compound powder. At the same time, the drive motor 34 is started, which will drive the turntable 33 to rotate. The turntable 33 drives the sliding column 35 to rotate, so that the sliding column 35 slides up and down inside the guide groove 32, thereby driving the rocker arm 31 to swing back and forth within a certain angle, so that the rocker arm 2 and the mixing tank 4 shake synchronously, so that the two end faces of the mixing tank 4 are reversed back and forth, which can further improve the uniformity and efficiency of raw material mixing.
