Description
Technical Field
[0001] The present invention relates to the field of surfactant mixing, and in particular to a mixing device which is convenient for switching stirring modes. Background Art
[0002] Cationic surfactants are mostly derivatives of organic nitrogen compounds, with the positive ion charge carried by the nitrogen atom. Some newer cationic surfactants also carry the positive ion charge on atoms such as phosphorus, sulfur, iodine, and arsenic. Based on their chemical structure, cationic surfactants can be divided into four main categories: amine salts, quaternary ammonium salts, heterocyclics, and arsenic salts.
[0003] The main reaction for synthesizing cationic surfactants is N-alkylation reaction, in which the reaction of tertiary amine with alkylating agent to form quaternary ammonium salt is also called quaternization reaction.
[0004] During the synthesis of cationic surfactants, multiple raw materials are added to a mixing barrel according to the amount, and then a stirring tool is used to mix the raw materials. However, the volume and density of each raw material are different. Therefore, during the mixing process, the lighter raw materials will stay in the upper half of the mixing barrel for a longer time, and the heavier raw materials will stay in the lower half of the mixing barrel for a longer time. Conventional mixing methods are not convenient for sufficient interactive mixing of the sinking and floating raw materials. During the mixing process, a large amount of raw materials will hang on the inner wall of the mixing barrel, thereby reducing the stirring and mixing effect of the cationic surfactant. Summary of the Invention

[0035] The mixing drum 2 also includes a stirring mechanism, which is arranged on the mixing drum 2, the hollow rotating shaft 61 and the vertical shaft 82. The stirring mechanism is used to stir the sinking and floating raw materials. The stirring mechanism includes a rotating ring 91, a porous ring 92, stirring blades 93, a convex ball 94, a sleeve rod 95, an outer spring 96, a push rod 97 and an inner spring 98. A rotating ring 91 is rotatably provided on both the upper and lower sides of the mixing drum 2. The two rotating rings 91 are symmetrically arranged.

[0036] There are twenty circular holes evenly spaced around the two porous rings 92. The two push rods 97 on the same side form a group. The diameter of the push rods 97 is smaller than the inner diameter of the circular holes on the porous ring 92. The two push rods 97 in each group are respectively located in two opposite circular holes of the porous ring 92 on the same side.
[0037] Initially, the discharge valve 5 is in a closed state, the operator opens the cover 4, and then adds an appropriate amount of raw materials to the mixing drum 2 through the feed pipe 3. The operator covers the cover 4, and then the operator starts the motor 64 to rotate. The motor 64 drives the hollow shaft 61, the horizontal shaft 62 and the mixing blade 63 to rotate through the transmission assembly 65. The mixing blade 63 can mix the raw materials of the mixing drum 2. Initially, the convex ball 94 presses against the sleeve rod 95, the outer spring 96 is in a stretched state, and the push rod 97 is stuck in the circular hole of the porous ring 92. The rotation of the hollow shaft 61 drives the sleeve rod 95, the outer spring 96, the push rod 97 and the inner spring 98 to rotate, and the push rod 97 drives the porous ring 92, the rotating ring 91 and the stirring blades 93 to rotate, and the stirring blades 93 on the upper and lower sides can stir the sinking and floating raw materials, so that the sinking and floating raw materials are loose and loose, so that the sinking and floating raw materials can be mixed more evenly with the raw materials suspended in the middle, thereby improving the effect of raw material stirring. Initially, the two-way nut 75 is located in the middle of the hollow two-way screw rod 74, and the four racks 84 are engaged with the four column gears 85. Through the engagement of the four racks 84 with the four column gears 85, the positions of the four horizontal shafts 62 and the four mixing blades 63 can be locked, so that the four mixing blades The blade 63 remains horizontal; the rotation of the hollow rotating shaft 61 drives the hollow bidirectional screw rod 74 to rotate, and the rotation of the hollow bidirectional screw rod 74 drives the bidirectional nut 75 and the two sliders 72 to move back and forth up and down along the guide frame 71, and the bidirectional nut 75 drives the connecting frame 73 and the vertical shaft 82 to move back and forth up and down, and the vertical shaft 82 drives the double flange column 83, the four racks 84 and the two convex balls 94 to move back and forth up and down, and when the bidirectional nut 75 drives the four racks 84 and the two convex balls 94 to move upward, the four racks 84 drive the four column gears 85 to rotate, and the four column gears 85 rotate to drive the four horizontal shafts 62 and the four mixing blades 63 After being flipped at a certain angle, the four mixing blades 63 can push the already mixed and loosened raw materials in the upper half of the mixing drum 2 downward; the two convex balls 94 move upward and gradually separate from the two sets of sleeve rods 95. Under the action of the outer spring 96, the two sleeve rods 95 of each group drive the two inner springs 98 and the two push rods 97 to move towards each other. The two push rods 97 will gradually separate from the two circular holes on the porous ring 92. At this time, the upper and lower sets of stirring blades 93 will no longer rotate, so as not to stir the raw materials in the mixing drum 2 and form turbulence, thereby improving the pushing and mixing effect of the raw materials in the mixing drum 2.When the bidirectional nut 75 moves downward to the middle on the hollow bidirectional screw rod 74, the bidirectional nut 75 drives the four racks 84 and the two convex balls 94 to move downward, and the four racks 84 drive the four column gears 85 to rotate in the opposite direction. The rotation of the four column gears 85 drives the four transverse shafts 62 and the four mixing blades 63 to flip in the opposite direction to a horizontal state. The two convex balls 94 move downward and gradually contact the two sets of sleeve rods 95. The outer spring 96 is stretched accordingly. The two sleeve rods 95 of each group drive the two inner springs 98 and the two ejector rods 97 to move away from each other. If the two ejector rods 97 are just stuck in two of the circular holes on the porous ring 92, the inner spring 98 will not be compressed. If the two ejector rods 97 are in contact with the inner wall of the porous ring 92, Then the two push rods 97 move toward each other, the two inner springs 98 are compressed, and the two push rods 97 move along the inner wall of the porous ring 92. When the two push rods 97 move to two of the circular holes on the porous ring 92, under the action of the two inner springs 98, the two push rods 97 will move toward each other. The two push rods 97 will be stuck in two of the circular holes on the porous ring 92, and the sleeve rod 95, the outer spring 96, the push rod 97 and the inner spring 98 are driven to rotate by the rotation of the hollow shaft 61. The push rod 97 drives the porous ring 92, the rotating ring 91 and the stirring blades 93 to rotate, and the stirring blades 93 on the upper and lower sides can stir the sinking and floating raw materials again; the two-way nut 75 is in the hollow two-way When the middle part of the screw rod 74 moves to the lower part, the two-way nut 75 drives the four racks 84 and the two convex balls 94 to continue to move downward, and the four racks 84 drive the four column gears 85 to continue to rotate in the opposite direction. The rotation of the four column gears 85 drives the four transverse shafts 62 and the four mixing blades 63 to flip in the opposite direction by a certain angle. After the four mixing blades 63 flip in the opposite direction, the already mixed and loose raw materials in the lower half of the mixing barrel 2 can be pushed upward; the two convex balls 94 will gradually separate from the two sets of sleeve rods 95 when they move upward. Under the action of the outer spring 96, the two sleeve rods 95 of each group drive the two inner springs 98 and the two ejector rods 97 to move in the direction close to each other. The two ejector rods 97 will gradually separate from the two on the porous ring 92. The circular holes are separated. At this time, the upper and lower sets of stirring blades 93 no longer rotate, thereby preventing the materials in the mixing drum 2 from being stirred and causing turbulence, thereby improving the propulsion and mixing effect of the materials in the mixing drum 2. This repetitive process allows the upper and lower sets of stirring blades 93 to intermittently stir and mix the materials in the upper and lower halves of the mixing drum 2. Moreover, when the materials in the upper and lower halves stop mixing, the inclination angle of the mixing blades 63 is changed to propel the mixed materials in the upper and lower halves of the mixing drum 2 upward or downward for mixing, thereby allowing both sinking and floating materials to be fully mixed, further improving the surfactant mixing effect.
[0038] Example 2: Based on Example 1, Figure 6-Figure 9As shown, it also includes a fixed square column 10, a scraper 101 and a return spring 103. Two fixed square columns 10 are fixedly installed on the two rotating rings 91 respectively. The two fixed square columns 10 on the same side of different rotating rings 91 are a group. A scraper 101 is slidingly provided between the two fixed square columns 10 of each group. A return spring 103 is respectively provided between the two ends of the scraper 101 and the two fixed square columns 10. The scraper 101 is in contact with the inner wall of the mixing drum 2.
[0039] When the rotating ring 91 rotates, it drives the fixed square column 10, the return spring 103 and the scraper 101 to rotate. The scraper 101 will rotate along the inner wall of the mixing drum 2. Under the action of the return spring 103, the two scrapers 101 can always stick to the inner wall of the mixing drum 2. The two scrapers 101 can scrape off the raw materials hanging on the inner wall, so that the raw materials can be mixed more evenly, and can reduce the occurrence of raw materials hanging on the inner wall of the mixing drum 2, further improving the effect of surfactant mixing.
[0040] Example 3: Based on Example 2, Figure 7-Figure 9 As shown, the inner side walls of the two porous rings 92 are each provided with an annular guide groove 11 , and the annular guide groove 11 and the twenty circular holes overlap with each other.
[0041] It also includes a guide ball 12. Each group of two push rods 97 has a guide ball 12 at one end away from each other. The guide ball 12 contacts the annular guide groove 11 on the inner wall of the porous ring 92.
[0042] The two push rods 97 drive the two guide balls 12 to move away from each other, and the two guide balls 12 are in contact with the annular guide groove 11. When the two push rods 97 move, they drive the two guide balls 12 to move along the annular guide groove 11, so that the two push rods 97 can move more smoothly, thereby improving the durability of the device.
