DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.
[0030] An embodiment of a production device for super refined adipic acid of the present invention is as follows Figures 1 to 10As shown, it includes a mixing mechanism 1 for processing raw materials, a heating mechanism 3 for heat preservation, and a control mechanism 4 for control, the heating mechanism 3 is wrapped and arranged outside the mixing mechanism 1, the bottom of the heating mechanism 3 is fixed on the machine base, the control mechanism 4 is installed at the front end of the machine base, the top of the mixing mechanism 1 is installed with a power mechanism 2 for providing power, and also includes a stirring and cooling mechanism 5 for mixing raw materials and a mixing mechanism 6 for providing state adjustment for the stirring and cooling mechanism 5, the stirring and cooling mechanism 5 is installed inside the mixing mechanism 1 and installed on the main shaft 21 of the power mechanism 2, the mixing mechanism 6 is installed at the cooling pipe 55 position of the stirring and cooling mechanism 5, the state matching mechanism 7 is installed at the bottom of the mixing mechanism 6, and the top of the mixing mechanism 6 is installed with a state adjustment mechanism 8 for driving the state change of the mixing mechanism 6;
[0031] The stirring and cooling mechanism 5 includes a stirring frame 51, and three groups of horizontal frames 52 are installed horizontally at the upper and lower ends of the stirring frame 51. The horizontal frames 52 are arranged in a circular array on the stirring frame 51. The upper and lower corresponding horizontal frames 52 form a group, and two cooling pipes 55 are vertically installed on each group of stirring frames 51. The mixing mechanism 6 includes a spiral blade 61, and the spiral blade 61 is wrapped around the cooling pipe 55, and the spiral blade 61 is rotatably connected to the cooling pipe 55. The upper end of the spiral blade 61 is equipped with a blade power component that drives it to rotate. The bottom of the spiral blade 61 is connected to a bottom matching gear set 64. The state matching mechanism 7 is used to cooperate with the stirring and cooling mechanism 5 and the bottom matching gear set 64 to change the spiral blade 61 between two states.
[0032] In this embodiment, chambers for transmitting coolant are formed inside the stirring frame 51 and the cross frame 52, and the cooling pipe 55 is connected to the chamber. The first state of the spiral blade 61 is that there is a gap between it and the cooling pipe 55 and it can rotate without restriction to assist in stirring the raw materials. The second state of the spiral blade 61 is that it is in close contact with the surface of the cooling pipe 55 and scrapes the surface of the cooling pipe 55 when rotating. The top of the stirring frame 51 is slidably matched with a cooling pipe connecting seat 53, and a cooling circulation pipe group 54 is installed on the top of the cooling pipe connecting seat 53. The cooling pipe connecting seat 53 is fixedly installed on the sealing cover 12 of the mixing mechanism 1.
[0033] In this embodiment, the blade power assembly includes a top matching gear set 62, a driving gear 63, and a matching gear ring 65. The top matching gear set 62 is fixedly connected to the upper end of the spiral blade 61. The top matching gear set 62 is composed of two meshing gears, one of which is provided with a driving gear 63 on the upper side. The driving gear 63 and its corresponding gear are matched through a transmission gear. The driving gear 63 and the corresponding gear are formed with tooth blocks that match the transmission gear. A matching gear ring 65 is provided on the outer side of the driving gear 63 and on the bottom surface of the sealing cover 12. A magnetic block 81 of the state adjustment mechanism 8 is installed on the top of the gear 63, and a plurality of electromagnets 82 are installed in a circular array corresponding to the position of the magnetic block 81 on the sealing cover 12. The top matching gear set 62 and the bottom matching gear set 64 are rotatably connected to the cooling pipe 55. When the stirring frame 51 and the cross frame 52 drive the top matching gear set 62 and the driving gear 63 to rotate, the driving gear 63 cooperates with the matching gear ring 65, so that the rotating power of the driving gear 63 drives the top matching gear set 62 to rotate through the transmission gear, so that the spiral blade 61 rotates and stirs the raw materials.
[0034] In this embodiment, the driving gear 63 and the transmission gear below it are connected to the cross frame 52 via a pin shaft, and the driving gear 63 slides up and down to cooperate with the gear ring 65.
[0035] In this embodiment, the state matching mechanism 7 includes a supporting spring 71, an adjusting gear 72, and a resistance block 73. The main shaft 21 passes through the stirring frame 51 and is provided with a bottom stirring blade 22 at the bottom. The stirring frame 51 is slidably connected to the main shaft 21 through a spline. A supporting spring 71 is provided between the bottom of the stirring frame 51 and the bottom stirring blade 22. The adjusting gear 72 is rotatably connected to the outside of the stirring frame 51. Four resistance blocks 73 are provided in a circular array corresponding to the position of the adjusting gear 72 in the stirring frame 51. An extrusion ring 74 is fixedly connected to the lower position of the main shaft 21 corresponding to the resistance block 73. When the stirring frame 51 descends, the stirring frame 51 is The resistance block 73 at the bottom is squeezed by the extrusion ring 74. At this time, the resistance block 73 expands outward and frictionally cooperates with the support spring 71. After the support spring 71 obtains the friction force, the rotation speed slows down, and the same resistance is transmitted to the bottom matching gear set 64. Then, the bottom of the spiral blade 61 obtains resistance, and the top of the spiral blade 61 obtains the power of the top matching gear set 62 to continue to rotate. Due to the spring characteristics, when the spring transitions to the spiral direction and twists, the inner diameter of the spiral blade 61 will shrink inward. At this time, the inner side of the spiral blade 61 is in close contact with the cooling tube 55 and rotates at the same time, so that the crystals adhered to the surface of the cooling tube 55 are scraped off.
[0036] In this embodiment, the top surface of the extrusion ring 74 and the end surface of the extrusion ring 74 corresponding to the inner side of the resistance block 73 are both formed with chamfers to facilitate the cooperation with the resistance block 73 when the resistance block 73 descends.
[0037] In this embodiment, the resistance block 73 is made of rubber.
[0038] In this embodiment, the spiral directions of adjacent spiral blades 61 are opposite. The spiral blades 61 are made of copper. Copper can conduct temperature better and has toughness and is easy to deform.
[0039] In this embodiment, the gap size between the inner side of the spiral blade 61 and the cooling pipe 55 ranges from 0 mm to 10 mm.
[0040] In this embodiment, the mixing mechanism 1 also includes a sealed tank 11, a sealing cover 12 is fixedly connected to the top of the sealed tank 11, an external feed pipe 13 is arranged on one side of the sealed tank 11, and a discharge pipe 14 is arranged at the bottom of the sealed tank 11. The heating mechanism 3 includes an electric heating insulation tank and a temperature controller wrapped around the outside of the sealed tank 11.
[0041] The working principle is as follows: after the raw materials are poured into the sealed tank 11, the motor of the power mechanism 2 is started, and the stirring frame 51 is driven to rotate as a whole through the main shaft 21. At this time, the driving gear 63 cooperates with the matching gear ring 65, so that the rotating power of the driving gear 63 drives the top matching gear set 62 to rotate through the transmission gear, so that the spiral blade 61 rotates and stirs the raw materials. At this time, the spiral blade 61 is in the first state, and there is a gap between the spiral blade 61 and the cooling tube 55 and it rotates without restriction, thereby assisting the stirring of the raw materials;
[0042] At the same time, the power-on state of the electromagnet 82 is controlled by detecting the internal raw material temperature. For example, by controlling the electromagnet 82 to generate the same magnetic pole as the magnetic block 81, the top matching gear set 62 is made to descend, and the entire stirring and cooling mechanism 5 is descended. When descending, the resistance block 73 inside the stirring frame 51 is squeezed by the extrusion ring 74. At this time, the resistance block 73 expands outward and rubs with the support spring 71. After the support spring 71 obtains the friction force, the rotation speed slows down, and the same resistance is transmitted to the bottom matching gear set 64. Then, the bottom of the spiral blade 61 obtains resistance, and the top of the spiral blade 61 obtains the power of the top matching gear set 62 to continue to rotate. Due to the spring characteristics, when the spring is twisted in the spiral direction, the inner diameter of the spiral blade 61 will shrink inward. At this time, the inner side of the spiral blade 61 is tightly attached to the cooling tube 55 and rotates at the same time, so that the crystals attached to the surface of the cooling tube 55 are scraped off.
[0043] Alternatively, the circular array of electromagnets 82 can be controlled to intermittently change the magnetic poles, so that the stirring frame 51 floats up and down during rotation, thereby randomly changing the state of the spiral blade 61, and also improving the stirring power. The cooling tube 55 does not pass through the cooling chamber under normal conditions, and the sealed tank 11 only ensures the mixing processing of the super-fine adipic acid through the heating of the heating mechanism 3. If a sudden temperature rise occurs, the cooling tube 55 is used to mix with cooling water. During mixing, due to the sudden drop in temperature, the raw materials may crystallize rapidly, resulting in instantaneous crystallization on the surface of the cooling tube 55. At this time, the weight caused by the instantaneous crystallization on the surface of the cooling tube 55 increases, and the stirring frame 51 sinks, so that the spiral blade 61 also enters the second state.
[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
