[0026] Compared with the prior art, the advantages and positive effects of the present invention are:
[0027] 1. In the present invention, by setting a heat-insulating structure, the heat-insulating cotton is adhered to the protective cover, and then the screw rod is rotated. The screw rod rotates and moves in the support arm with the help of the thread. The movement of the screw rod drives the protective cover to move toward the heating chamber. The movement of the protective cover drives the heat-insulating cotton to move.

At this time, the hot air in the heating chamber will dissipate from the rectangular hole, and then the hot air in the heating chamber will be quickly dissipated, thereby shortening the heat dissipation time, facilitating the removal of the intermediate of vitamin B12 production in the tank from the processing tank, improving the efficiency of the production process, and thus improving the overall production capacity.
[0029] 3. In the present invention, by setting a supporting structure, the collection box can be placed on the surface of the support plate, and the collection box will fit on the surface of the support plate. After the collection box is placed, the bolt is rotated, and the bolt will move in the ring with the help of the thread until the bolt is out of contact with the leg, and then the support plate is pushed in the direction close to the discharge pipe. The support plate will drive the ring to slide along the surface of the leg, and at the same time drive the collection box to move in the direction close to the discharge pipe. When the collection box moves to a suitable position, the bolt is rotated in the opposite direction until the bolt abuts on the surface of the leg. At this time, the intermediate of vitamin B12 production flowing out of the discharge pipe will fall into the collection box. Since the height of the collection box is relatively high, the splashing of the intermediate of vitamin B12 production due to the large drop can be avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein.

The surface of the heating chamber 12 is provided with a heat dissipation structure 8. By providing the heat dissipation structure 8, it is convenient to quickly dissipate the hot air in the heating chamber 12, thereby shortening the heat dissipation time, facilitating the removal of the intermediate of vitamin B production in the tank from the processing tank 1, improving the efficiency of the production process, and thus improving the overall production capacity. The surface of a plurality of legs 2 is provided with a support structure 9. By providing the support structure 9, when the intermediate of vitamin B production is taken out of the processing tank 1, the intermediate of vitamin B production is prevented from splashing due to the excessive distance between the feeding tube 6 and the collecting box.
[0043] like Figure 3 and Figure 4 and Figure 5 As shown, the heat preservation structure 7 includes two support arms 71, both of which are fixedly connected to the arc surface of the treatment tank 1. The surfaces of the two support arms 71 are threaded with screw rods 72, and the end of the screw rod 72 close to the treatment tank 1 is rotatably connected to the protective cover 73, and the inner wall of the protective cover 73 is glued with heat insulation cotton 74. A rectangular rod 75 is slidably penetrated through the surface of the support arm 71, and one end of the rectangular rod 75 is fixedly connected to the surface of the protective cover 73. The rectangular rod 75 moves and slides in the support arm 71, and the rectangular rod 75 can prevent the protective cover 73 from rotating when moving. The end of the screw rod 72 away from the protective cover 73 is fixedly connected to a turntable 76, and the vertical section of the turntable 76 is cross-shaped. The rotation of the turntable 76 will drive the screw rod 72 to rotate, and the turntable 76 can facilitate the rotation of the screw rod 72. The inner wall of the protective cover 73 is fixedly connected with a plurality of spikes 77, and the surface of the spikes 77 is fixedly connected with two barbs 78. The spikes 77 in the protective cover 73 will penetrate into the thermal insulation cotton 74, and the spikes 77 will drive the barbs 78 to be inserted into the thermal insulation cotton 74, thereby further improving the stability of the thermal insulation cotton 74 being limited in the protective cover 73.
[0044] like Figure 6 and Figure 7 and Figure 8 As shown, the heat dissipation structure 8 includes two rectangular holes 81, and the two rectangular holes 81 are both opened on the arc surface of the heating chamber 12. The arc surface of the heating chamber 12 is fixedly connected with a plurality of limit frames 82. The plurality of limit frames 82 are grouped in pairs, and a group of limit frames 82 is respectively fixed on both sides of the rectangular hole 81. The surface of the limit frame 82 is slidably penetrated with a latch 83. The inner walls of the two limit frames 82 are both slidably inserted with limit arms 85. One end of the two limit arms 85 is fixedly connected with a rectangular plate 84, and the size of the rectangular plate 84 is adapted to the size of the rectangular hole 81. The surface of the rectangular plate 84 is fixedly connected with a sealing ring 86, and the sealing ring 86 is made of rubber. The sealing ring 86 on the surface of the rectangular plate 84 will fit tightly against the inner wall of the rectangular hole 81. The sealing ring 86 will be deformed when squeezed. The sealing ring 86 can improve the airtightness between the rectangular plate 84 and the rectangular hole 81, and further improve the effect of preventing hot air from flowing out of the gap. One end of the latch 83 is fixedly connected with a protrusion 87, and one side of the protrusion 87 is tapered. The latch 83 will drive the protrusion 87 to insert into the limit frame 82. Because the protrusion 87 is tapered, it is easy to insert the latch 83 into the limit frame 82. The surface of the rectangular plate 84 is fixedly connected with a connecting plate 88. The surface of the thermal insulation cotton 74 is provided with a through hole, and the size of the through hole is adapted to the size of the connecting plate 88. When the protective cover 73 drives the sealing gasket to cover the surface of the heating chamber 12, the connecting plate 88 on the surface of the rectangular plate 84 will be inserted into the through hole provided on the surface of the sealing gasket until the connecting plate 88 fits the inner wall of the protective cover 73. The protective cover 73 squeezes the rectangular plate 84 with the help of the connecting plate 88, thereby further improving the installation stability of the rectangular plate 84.
[0045] like Fig. 9 As shown, the support structure 9 includes a plurality of circular rings 91, which are sleeved on the arc surface of the support leg 2, and the surface of the circular rings 91 is threaded with bolts 92, and the surfaces of the plurality of circular rings 91 are fixedly connected with support plates 93. The surface of the support plate 93 is fixedly connected with a plurality of anti-slip strips 94, and the collection box will fit on the surface of the anti-slip strips 94, and the anti-slip strips 94 can improve the friction between the collection box and the support plate 93, thereby preventing the collection box from sliding off the surface of the support plate 93.
[0046] The overall working principle is that when it is necessary to improve the thermal insulation performance of the heating chamber 12, the thermal insulation cotton 74 is first glued to the protective cover 73, and the spikes 77 in the protective cover 73 will penetrate into the thermal insulation cotton 74, and the spikes 77 will drive the barbs 78 to be inserted into the thermal insulation cotton 74, thereby further improving the stability of the thermal insulation cotton 74 limited in the protective cover 73, and then the turntable 76 is rotated. The rotation of the turntable 76 will drive the screw rod 72 to rotate, and the rotation of the screw rod 72 will move in the support arm 71 with the help of the thread. The movement of the screw rod 72 will drive the protective cover 73 to move in the direction close to the heating chamber 12, and the movement of the protective cover 73 will drive the thermal insulation cotton 74 to move. When the protective cover 73 moves, it will drive the rectangular rod 75 to move. The movement of the rectangular rod 75 will slide in the support arm 71, and the rectangular rod 75 can prevent the protective cover 73 from rotating when it moves. When the protective cover 73 is attached to the surface of the treatment tank 1, the protective cover 73 will drive the thermal insulation cotton 74 to fit the surface of the heating chamber 12.
[0047] When rapid heat dissipation is required, first pull the latch 83, and the latch 83 will move and slide in the limit frame 82. When the latch 83 is pulled out of the limit frame 82, pull the rectangular plate 84, and the rectangular plate 84 will drive the limit plate to slide out of the limit frame 82, thereby taking the rectangular plate 84 out of the rectangular hole 81. At this time, the hot air in the heating chamber 12 will dissipate from the rectangular hole 81, and then quickly dissipate the hot air in the heating chamber 12. When the baffle plate needs to be placed in the rectangular hole 81, first align the rectangular plate 84 with the rectangular hole 81 and put it in. The rectangular plate 84 will slide into the rectangular hole 81, and the rectangular plate 84 will drive the limit arm 85 to slide into the limit frame 82. At this time, the sealing ring 86 on the surface of the rectangular plate 84 will fit tightly against the inner wall of the rectangular hole 81, and the sealing ring 86 will be squeezed and deformed The sealing ring 86 improves the airtightness between the rectangular plate 84 and the rectangular hole 81, and further improves the effect of preventing hot air from flowing out of the gap. Then the pin 83 is pressed, and the pin 83 drives the protrusion 87 to insert into the limit frame 82. The pin 83 reaches the position of the limit arm 85, thereby limiting the position of the baffle. Because the protrusion 87 is conical, it is convenient to insert the pin 83 into the limit frame 82. After the rectangular plate 84 is installed, when the protective cover 73 drives the sealing gasket to cover the surface of the heating chamber 12, the connecting plate 88 on the surface of the rectangular plate 84 will be inserted into the through hole opened on the surface of the sealing gasket until the connecting plate 88 fits against the inner wall of the protective cover 73. The protective cover 73 squeezes the rectangular plate 84 with the help of the connecting plate 88, thereby further improving the installation stability of the rectangular plate 84.
[0048] When it is necessary to take out the intermediate of vitamin B12 production in the processing tank 1 from the processing tank 1, first put the collection box on the surface of the support plate 93, and the collection box will fit on the surface of the anti-slip strip 94. The anti-slip strip 94 can increase the friction between the collection box and the support plate 93, thereby preventing the collection box from sliding off the surface of the support plate 93. When the collection box is placed, turn the bolt 92, and the bolt 92 will move in the ring 91 with the help of the thread until the bolt 92 is out of contact with the support leg 2, and then push the support plate 93 in the direction close to the discharge pipe 6. The support plate 93 will drive the ring 91 to slide along the surface of the support leg 2, and at the same time drive the collection box to move in the direction close to the discharge pipe 6. When the collection box moves to the appropriate position, turn the bolt 92 in the opposite direction until the bolt 92 abuts on the surface of the support leg 2. At this time, the intermediate of vitamin B12 production flowing out of the discharge pipe 6 will fall into the collection box. Because the height of the collection box is relatively high, the splashing of the intermediate of vitamin B12 production due to the large drop can be avoided.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
