Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid material storage technology, specifically to a liquid material insulated storage tank. Background Technology
[0002] Hexamethylenediamine piperidine (CAS No.: 61260-55-7), an intermediate for light stabilizers, is an important intermediate in the production of hindered amine light stabilizers. Hindered amine light stabilizers can improve the performance of plastics under strong light conditions and are mainly used in the automotive and construction industries, as well as agricultural films. The production process of hexamethylenediamine piperidine involves adding the material to be hydrogenated and the catalyst into a reactor, replacing part of the gas in the reactor space with nitrogen 4-5 times, and then starting the heating reaction. After the reaction is completed, the temperature is lowered to remove the unreacted hydrogen in the upper part of the reactor. The hydrogen is then replaced with nitrogen 4-5 times, and the reactor is allowed to stand. After the catalyst settles for 1 hour, the upper product is pressed out.
[0003] When storing hexamethylenediamine piperidine liquid under heat preservation conditions, heating pipes are usually installed on the outside of the tank to heat and preserve the inside of the tank. This method can easily lead to a temperature difference between the liquid temperature at the center of the tank and the liquid temperature near the tank wall, resulting in inconsistent heat preservation temperatures. To address this issue, we propose a liquid material heat preservation storage tank. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Example 1
[0017] Reference Figure 1 , 2This is the first embodiment of the present invention, which provides a liquid material heat-insulating storage tank, including a tank body 1, with a heating coil 2 fixedly connected to the outer wall of the tank body 1. The tank body 1 is characterized by a support plate 8 fixedly sleeved at the top, a hinge interface 18 at the center of the support plate 8, a transmission seat 17 slidably engaging within the hinge interface 18, a rotating shaft 15 rotatably sleeved within the transmission seat 17, a driven bevel gear 13 fixedly connected to one end of the rotating shaft 15, and a plurality of stirring rods 16 fixedly connected to the other end of the rotating shaft 15, with the driven bevel gear 13 meshing with it. A fixed bevel gear 12 is connected to one end of the housing of the reducer 11. Both ends of the reducer 11 are fixedly connected to one end of the support base 10. The other end of the support base 10 is fixedly connected to the inner wall of the top of the tank 1. One end of the drive shaft of the reducer 11 is fixedly connected to one end of the active connecting rod 14. The other end of the active connecting rod 14 is rotatably sleeved on the outer wall of the rotating shaft 15. The other end of the drive shaft of the reducer 11 is fixedly connected to the output shaft of the explosion-proof motor 9. The explosion-proof motor 9 is fixedly installed on the inner wall of the top of the tank 1.
[0018] Using a water pump and pipeline, insulated hot water is injected through the inlet pipe 21 of the heating coil 2 to heat and insulate the liquid material inside the tank 1. During heating and insulation, the explosion-proof motor 9 is powered on. The explosion-proof motor 9, in conjunction with the reducer 11, drives the active connecting rod 14 to rotate circumferentially. The active connecting rod 14 drives the rotating shaft 15 to rotate circumferentially around the tank 1. The rotating shaft 15 is tilted, and the rotating shaft 15 then drives the fixed stirring rod 16 to agitate the liquid material inside and outside the tank 1. At the same time, when the rotating shaft 15 rotates circumferentially, it drives the fixed driven bevel gear 13 to rotate synchronously. The driven bevel gear 13, in conjunction with the fixed bevel gear 12, drives the rotating shaft 15 to rotate. The rotating shaft 15 then drives the stirring rod 16 to rotate, further agitating the liquid material inside the tank 1, causing the liquid material inside and outside the tank 1 to flow towards the center, thus preventing a temperature difference between the inside and outside of the liquid material inside the tank 1.
[0019] Example 2
[0020] Reference Figure 1-2 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, one end of the heating coil 2 is fixedly connected to a water inlet pipe 21, and the other end of the heating coil 2 is fixedly connected to a water outlet pipe 22. Insulation hot water is injected through the water inlet pipe 21 of the heating coil 2 to heat and insulate the liquid material inside the tank 1. The water outlet pipe 22 is set to circulate the insulation hot water inside the heating coil 2.
[0021] Specifically, several support legs 3 are fixedly connected to the bottom of the tank body 1, a discharge pipe 4 is fixedly connected to the center of the bottom of the tank body 1, and a feed pipe 5 is fixedly connected to the top outer wall of one side of the tank body 1. The liquid material that needs to be kept warm is injected into the tank body 1 through the feed pipe 5. A valve is installed on the discharge pipe 4. The discharge of the liquid material inside the tank body 1 is controlled by opening and closing the valve.
[0022] Specifically, a thermometer 6 is fixedly installed on one side of the top of the tank 1. The thermometer 6 is fixedly inserted into the tank 1 after passing through the top wall and the support plate 8. The thermometer 6 adopts the thermometer structure commonly used in insulated storage tanks in the prior art. The thermometer 6 monitors the temperature inside the tank 1.
[0023] Specifically, one side of the gas pipe 7 is fixedly connected to the top of the tank 1, and the other end of the gas pipe 7 is fixedly connected to the support plate 8. The gas pipe 7 is connected to the interior of the tank 1. Several gas holes 71 are opened on the gas pipe 7. The gas holes 71 are located between the inner wall of the top of the tank 1 and the support plate 8. Nitrogen and other gases are injected into the interior of the tank 1 through the gas pipe 7 to realize the preparation of the light stabilizer intermediate hexamethylenediamine piperidine. The setting of the gas holes 71 allows for gas extraction or injection into the space between the top wall of the tank 1 and the support plate 8.
[0024] Specifically, the stirring rods 16 are evenly distributed around the rotating shaft 15, and the stirring rods 16 have a U-shaped structure. The rotating shaft 15 is inclined. When the rotating shaft 15 rotates around the tank 1, it drives the fixed stirring rods 16 to agitate the liquid material inside and outside the tank 1. At the same time, when the rotating shaft 15 rotates, it drives the fixed driven bevel gear 13 to rotate synchronously. The driven bevel gear 13 cooperates with the fixed bevel gear 12, and when the driven bevel gear 13 rotates, it drives the rotating shaft 15 to rotate. The rotating shaft 15 then drives the stirring rods 16 to rotate, further agitating the liquid material inside the tank 1, causing the liquid material inside and outside the tank 1 to flow towards the center, and avoiding temperature differences between the inside and outside of the liquid material inside the tank 1.
[0025] Using a water pump and pipeline, insulated hot water is injected through the inlet pipe 21 of the heating coil 2 to heat and insulate the liquid material inside the tank 1. During heating and insulation, the explosion-proof motor 9 is powered on. The explosion-proof motor 9, in conjunction with the reducer 11, drives the active connecting rod 14 to rotate circumferentially. The active connecting rod 14 drives the rotating shaft 15 to rotate circumferentially around the tank 1. The rotating shaft 15 is tilted, and the rotating shaft 15 then drives the fixed stirring rod 16 to agitate the liquid material inside and outside the tank 1. At the same time, when the rotating shaft 15 rotates circumferentially, it drives the fixed driven bevel gear 13 to rotate synchronously. The driven bevel gear 13, in conjunction with the fixed bevel gear 12, drives the rotating shaft 15 to rotate. The rotating shaft 15 then drives the stirring rod 16 to rotate, further agitating the liquid material inside the tank 1, causing the liquid material inside and outside the tank 1 to flow towards the center, thus preventing a temperature difference between the inside and outside of the liquid material inside the tank 1.
