Technical Field

[0001] The invention relates to the field of raw material mixing, in particular to a premixing device for processing a cationic surfactant. Background Art

[0002] Cationic surfactant is a product of mixing multiple raw materials. Before processing the surfactant, the staff often premixes the multiple raw materials. During the premixing process, in order to improve the premixing efficiency, the staff usually continuously put raw materials into the container during the mixing and discharging process, so as not to affect the continuity of the feeding, so as to achieve the purpose of rapid premixing.

[0011] The beneficial effects of the present invention are as follows: 1. The present invention drives the rotating drum, rotating roller and gear to swing slightly together through a motor, and the gear drives the rotating roller and the stirring frame to reciprocate and rotate together through the gear ring to mix the various raw materials in the fixed ring. After a part of the raw materials are mixed, the motor drives the rotating drum and the guide plate to rotate 180 degrees together, thereby causing the fixed rings on both sides to shift positions. During the shifting process, the fixed ring rotates so that the lower pressure frame drives the guide bucket to move downward through the oblique recess of the guide frame and disengage from the rotating roller. The mixed raw materials flow out into the processing box through the guide bucket, and the lower pressure rod continues to rotate through the oblique recess of the guide frame to pull the guide bucket to reset. In this way, while the raw materials are mixed and discharged, the discharge pipe continues to discharge the raw materials uninterruptedly, thereby making the premixing of the raw materials faster, thereby improving the efficiency of the premixing.

[0012] 2. When the rotating roller rotates, it will drive the piston rod and the guide ring to rotate together. The fixed rod squeezes the bidirectional thread groove of the guide ring to make the piston rod reciprocate up and down. The up and down reciprocating movement of the piston rod will continuously suck the raw materials at the bottom of the fixed ring into the cavity of the rotating roller through the liquid inlet one-way valve, and at the same time, the raw materials in the cavity of the rotating roller will be discharged into the upper layer through the liquid outlet one-way valve and the discharge rod, thereby continuously stirring the raw materials in the upper and lower layers, so that the raw materials are premixed more evenly, thereby making the premixing more effective.

[0013] 3. Before premixing, the staff will start the fan first. The fan will inject external air into the slide groove of the piston rod through the air guide tube and be blocked by the bottom of the slide rod to generate high-pressure gas. At the same time as the raw materials enter the cavity of the rotating roller, the piston rod and the guide ring move upward to push the air guide tube and the slide rod to move upward together. The upward movement of the slide rod will be stopped by the contact rod and will no longer move. The piston rod and the air guide tube will continue to move upward, which will make the bottom of the slide rod no longer block the slide groove of the piston rod. Then the piston rod and the air guide tube will reset downward, and the tension spring will reset the slide rod, which will reset the slide rod and block the slide groove of the piston rod again. In this way, every time the raw material enters the cavity of the rotating roller, the high-pressure gas will quickly spray into the cavity of the rotating roller through the slide groove of the piston rod, and the injected high-pressure gas will mix the raw materials in the cavity of the rotating roller, so that the mixing of the raw materials will be more sufficient, thereby enhancing the premixing effect.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example 1: A premixing device for processing a cationic surfactant, such as Figure 1-Figure 12As shown, it includes a shell 1, a motor bracket 3 is welded on the shell 1, a driving motor 4 is connected to the motor bracket 3 by bolts, a connecting frame 5 is connected to the outside of the driving motor 4 by bolts, a feeding pipe 6 is connected to the connecting frame 5 by bolts, and the feeding pipe 6 is used to uniformly feed a variety of raw materials, a rotating cylinder 51 is connected to the bottom of the output shaft of the driving motor 4 by bolts, circular holes are opened on both sides of the rotating cylinder 51, a guide plate 61 is welded on the rotating cylinder 51, two inclined surfaces are arranged in the guide plate 61, the two inclined surfaces of the guide plate 61 are used to guide the raw materials, the feeding pipe 6 is aligned with one of the circular holes of the rotating cylinder 51, a unloading mechanism for unloading is arranged on the motor bracket 3, and a rotating mechanism for mixing a variety of raw materials is also arranged on the motor bracket 3.

[0029] The unloading mechanism includes a guide frame 71, and the two guide frames 71 are connected to the motor bracket 3 by bolts. The two guide frames 71 are parallel, and fixing rings 73 are welded in the two circular holes of the rotating cylinder 51, and support plates 74 are welded on the two fixing rings 73. The two support plates 74 are slidably connected with lower pressure frames 76, and the two lower pressure frames 76 are symmetrically arranged. The tops of the two lower pressure frames 76 are slidably connected to the gap between the two guide frames 71, and guide buckets 75 are welded to the bottoms of the two lower pressure frames 76. Discharge ports are opened at the bottoms of the two guide buckets 75, and the two guide buckets 75 are respectively slidably connected to the inner walls of the two fixing rings 73, and the guide buckets 75 are used to discharge raw materials.

[0030] One side of the two guide frames 71 is provided with an oblique recess, and the oblique recess of the guide frames 71 is used to drive the pressing frame 76 to move up and down.

[0031] The rotating mechanism includes a gear ring 81, which is connected to the motor bracket 3 by bolts. The outer side of the guide plate 61 is connected with a bottom plate 82 and a cover plate 83 by bolts. The bottom plate 82 is located below the gear ring 81. Both sides of the bottom plate 82 are slidingly connected to the two lower pressure frames 76. The bottom plate 82 is used to block the raw materials splashed during mixing. Both sides of the bottom plate 82 are rotatably connected with rotating rollers 84, and a cavity is provided in the rotating rollers 84. The two rotating rollers 84 are respectively located in the two fixed rings 73. The bottoms of the two rotating rollers 84 block the discharge ports of the two guide buckets 75 respectively. The upper parts of the two rotating rollers 84 are connected with gears 85 by flat keys. The two gears 85 are meshed with the gear ring 81. The outer sides of the two rotating rollers 84 are welded with stirring frames 86, and the stirring frames 86 are used to stir the raw materials.

[0032] First, the staff installs the shell 1 on the processing box of the active agent, so that the various raw materials are premixed inside the shell 1 and then enter the processing box of the active agent from the bottom of the shell 1. Then the staff continuously drops the various raw materials into one of the fixed rings 73 through the discharge pipe 6 and starts the motor at the same time. The motor drives the rotating cylinder 51, the guide plate 61 and the fixed ring 73 to swing slightly. The small swing of the fixed ring 73 will drive the rotating roller 84 and the gear 85 to swing together through the support plate 74. The gear 85 drives the rotating roller 84 to rotate back and forth through the ring gear 81. The rotation of the rotating roller 84 will drive the stirring frame to rotate back and forth, thereby mixing the various raw materials in the fixed ring 73. Under the action of the bottom plate 82, the raw materials are not easy to spill out during mixing. After a part of the mixing is completed, the motor drives the rotating cylinder 51, the guide plate 61 and the fixed ring 73 to rotate 180 degrees, thereby exchanging the positions of the fixed rings 73 on both sides. During the interchange process, the lower The continuous discharge of materials in the material tube 6 will fall into the other fixed ring 73 through one of the inclined surfaces of the guide plate 61, thereby preventing the material from being wasted. At the same time, the rotation of the fixed ring 73 will drive the lower pressure frame 76 and the guide bucket 75 to rotate. When the lower pressure frame 76 rotates to the oblique depression of the guide frame 71, the oblique depression of the guide frame 71 will first drive the guide bucket 75 to move downward by squeezing the lower pressure frame 76. The downward movement of the guide bucket 75 will disengage from the rotating roller 84, and the mixed raw materials will flow out through the guide bucket 75 and then enter the processing box. The continued rotation of the lower pressure rod will pull the guide bucket 75 upward along the oblique depression of the guide frame 71 to reset. The reset guide bucket 75 will contact the bottom of the rotating roller 84 again. In this way, while mixing and discharging the raw materials, the discharge pipe 6 continues to discharge materials uninterruptedly, thereby making the premixing of the raw materials faster, thereby improving the efficiency of the premixing. After the premixing is completed, the staff can turn off the motor and stop injecting the raw materials.

[0033] Embodiment 2: Based on embodiment 1, Figure 2-Figure 8As shown, it also includes a stirring mechanism, which is arranged on the rotating roller 84, and is used to stir the raw materials of the upper and lower layers. The stirring mechanism includes a piston rod 91, and the two piston rods 91 are respectively slidably connected in the cavities of the two rotating rollers 84, and a sliding groove is opened in the piston rod 91. The top of the piston rod 91 protrudes out of the rotating roller 84, and the tops of the two piston rods 91 are both connected to guide rings 92 by bolts, and the guide rings 92 are located above the rotating roller 84. The outer sides of the two guide rings 92 are both provided with bidirectional thread grooves, and fixing rods 93 are welded on both sides of the cover plate 83, and the two fixing rods 93 are respectively connected to the bidirectional grooves of the two guide rings 92 The threaded groove is connected in a sliding manner, and the fixed rod 93 drives the piston rod 91 to move reciprocatingly up and down through the bidirectional threaded groove of the guide ring 92. The bottom of the sides of the two rotating rollers 84 are connected with four liquid inlet check valves 94 and four liquid outlet check valves 95 by bolts. The four liquid inlet check valves 94 and the four liquid outlet check valves 95 on the same rotating roller 84 are arranged in a staggered manner. Four discharge rods 96 are welded to the outer sides of the two rotating rollers 84. Several of the discharge rods 96 are respectively connected to several of the liquid outlet check valves 95. A liquid outlet hole is opened on the top of each of the discharge rods 96. The discharge rod 96 is used to discharge the sucked lower layer raw materials to the upper layer through the liquid outlet hole of the discharge rod 96.

[0034] When the rotating roller 84 rotates, it will drive the piston rod 91 and the guide ring 92 to rotate together. The fixed rod 93 will squeeze the two-way thread groove of the guide ring 92 to make the piston rod 91 move upward first. The upward movement of the piston rod 91 will suck the raw material at the bottom of the fixed ring 73 into the cavity of the rotating roller 84 through the liquid inlet check valve 94. Then the guide ring 92 continues to rotate, and the fixed rod 93 squeezes the two-way thread groove of the guide ring 92 to make the piston rod 91 reset downward. The downward reset of the piston rod 91 will squeeze the raw material in the cavity of the rotating roller 84 into the discharge rod through the liquid outlet check valve 95. 96, and then the raw material is discharged to the upper layer from the liquid outlet of the discharge rod 96, and this is repeated. The fixed rod 93 will squeeze the two-way threaded groove of the guide ring 92 to make the piston rod 91 reciprocate up and down. The up and down reciprocating movement of the piston rod 91 will continuously suck the raw material at the bottom of the fixed ring 73 into the cavity of the rotating roller 84 through the liquid inlet one-way valve 94, and at the same time, the raw material in the cavity of the rotating roller 84 is discharged into the upper layer through the liquid outlet one-way valve 95 and the discharge rod 96, thereby continuously stirring the raw materials of the upper and lower layers, so that the raw material premixing is more uniform, thereby making the premixing more effective.

[0035] Embodiment 3: Based on embodiment 2, Figure 9-12As shown, a pressurizing mechanism is also included, the pressurizing mechanism is arranged on the cover plate 83, the pressurizing mechanism is used to mix the raw materials in the cavity of the rotating roller 84, the pressurizing mechanism includes a contact rod 101, two contact rods 101 are respectively welded on both sides of the cover plate 83, the two contact rods 101 are slidably connected with a connecting plate 102, one side of the two connecting plates 102 is bolted to a fan 103, the air outlets of the two fans 103 are bolted to an air guide 104, the other ends of the two air guide ducts 104 are respectively connected to two The top of each piston rod 91 is rotatably connected, and the two air guide tubes 104 are respectively connected to the slide grooves of the two piston rods 91. Slide rods 105 are slidably connected in the slide grooves of the two piston rods 91. The bottoms of the two slide rods 105 respectively block the slide grooves of the two piston rods 91. The tops of the two slide rods 105 are respectively slidably connected to the two air guide tubes 104. A tension spring 106 is connected between the slide rod 105 and the air guide tube 104 through a hook, and a sealing ring 107 is fixedly connected to the bottom of the slide rod 105 and one side of the air guide tube 104.

[0036] Before premixing, the staff starts the fan 103 first, and the fan 103 will inject external air into the slide groove of the piston rod 91 through the air guide pipe 104 and be blocked by the bottom of the slide rod 105 to generate high-pressure gas. When the raw materials enter the cavity of the rotating roller 84, the piston rod 91 and the guide ring 92 move upward and push the connecting plate 102, the air guide pipe 104 and the fan 103 to move upward together. The upward movement of the air guide pipe 104 will drive the slide rod 105 to move upward together through the tension spring 106. The upward movement of the slide rod 105 will contact the contact rod 101, and the contact rod 101 will resist the top of the slide rod 105 and stop moving. The piston rod 91 and the air guide pipe 104 continue to move upward. The bottom of the slide bar 105 no longer blocks the slide groove of the piston rod 91, the tension spring 106 is pulled, and then the piston rod 91 and the air guide tube 104 are reset downward, the contact rod 101 no longer resists the slide bar 105, the tension spring 106 is reset to drive the slide bar 105 to reset, and the slide bar 105 is reset to block the slide groove of the piston rod 91 again. In this way, each time the raw material enters the cavity of the rotating roller 84, the high-pressure gas will be quickly sprayed into the cavity of the rotating roller 84 through the slide groove of the piston rod 91, and the sprayed high-pressure gas will mix the raw materials in the cavity of the rotating roller 84, so that the mixing of the raw materials is more sufficient, thereby enhancing the premixing effect. After the premixing is completed, the staff also needs to turn off the fan 103.
