Description

Technical Field

[0001] This utility model relates to the field of liquid ammonia storage tank technology, specifically a liquid ammonia cryogenic storage tank with heat insulation function. Background Technology

[0002] Liquid ammonia, also known as anhydrous ammonia, is a colorless liquid with a strong, pungent odor. It is a widely used raw material in industry and is usually stored in pressure-resistant steel cylinders or tanks during transportation. Because liquid ammonia is obtained by pressurizing or cooling ammonia gas, the molecules in liquid ammonia are extremely prone to volatilization at higher temperatures.

[0003] Existing storage tanks for transporting liquid ammonia often require the use of chemicals to ensure the stability of ammonia gas in the ammonia solution. After the chemicals react with the ammonia solution, the resulting flocculent material adsorbs excess substances from the ammonia solution, thus ensuring the purity of the ammonia solution. However, after the reaction is complete, the flocculent material is discharged from the pipeline along with the ammonia solution. Furthermore, because the flocculent material tends to accumulate together, it can easily clog the pipeline. Therefore, a cryogenic liquid ammonia storage tank with heat insulation function is proposed. Utility Model Content

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-4A cryogenic liquid ammonia storage tank with heat insulation function includes a chassis 100, a connecting tank assembly 200, a transmission assembly 300, a tank platform assembly 400, a disc-shaped tube 500, a positioning bushing 600, a stirring assembly 700, and a partition plate 800. The connecting tank assembly 200 includes a tank body 210 disposed on top of the chassis 100, a discharge pipe 220 installed on the outer wall of the tank body 210, and a valve body 230 disposed on the outer wall of the discharge pipe 220. The transmission assembly 300 includes a support plate 310 disposed on the outer wall of the tank body 210, a housing 320 disposed at the top of the support plate 310, a pump body 330 installed on the side of the housing 320 away from the support plate 310, a gas guide pipe 340 disposed on the outer wall of the pump body 330, and a mounting assembly 350 disposed on the outer wall of the support plate 310. The mounting assembly 350 includes a mounting plate 351 disposed on the outer wall of the housing 320. A mounting platform 352 is mounted on the outer wall of the mounting plate 351. A filter hole 353 is formed on the outer wall of the mounting platform 352. A screw 360 is provided at the end of the mounting plate 351 away from the mounting platform 352. The screw 360 penetrates the mounting assembly 350 and is fixed to the housing 320 by a threaded connection. The pump body 330 and the air guide pipe 340 are integrated, and the air guide pipe 340 penetrates the trapezoidal tank platform 410. A disc-shaped tube 500 is provided at the end of the support plate 310 away from the housing 320. The threaded connection between the screw 360 and the housing 320 facilitates the installation and removal of the mounting plate 351 by workers and facilitates subsequent equipment maintenance. A trapezoidal tank platform 410 (340 through) facilitates the recovery and transfer of ammonia. The inner wall of the tank 210 is equipped with a baffle 800, the diameter of which matches the diameter of the inner wall of the tank 210. A disc-shaped tube 500 is located directly below the baffle 800. Positioning bushings 600 are installed on the inner wall of the tank 210, symmetrically distributed on the outer wall of the disc-shaped tube 500. The baffle 800's diameter matches the diameter of the inner wall of the tank 210, allowing it to effectively block and isolate the ammonia during agitation. The positioning bushings 600, installed on the inner wall of the tank 210, secure the disc-shaped tube 500. The disc-shaped tube 500 is disc-shaped and positioned on the inner wall of the tank 210. The tank platform assembly 400 includes components located at the top of the tank 210. The trapezoidal tank platform 410 has a feed pipe 420 installed on the side away from the tank body 210. The outer wall of the feed pipe 420 is provided with a sealing sleeve 430. The stirring assembly 700 includes a drive motor 710 disposed on the outer wall of the trapezoidal tank platform 410. The output end of the drive motor 710 is fixedly connected to a drive shaft 720. The outer wall of the drive shaft 720 is provided with stirring rods 730. The stirring rods 730 are distributed in a linear array on the outer wall of the drive shaft 720, and the length of the stirring rods 730 increases from high to low on the outer wall of the drive shaft 720. This allows the stirring rods 730 to increase the stirring rate of the ammonia water when stirring the ammonia water, and effectively increase the contact area between the ammonia water and the volatile ammonia gas.This effectively prevents ammonia leakage. The feed pipe 420 and the trapezoidal tank platform 410 are integrated devices, and the sealing sleeve 430 is fitted onto the feed pipe 420. The sealing sleeve 430 is mainly made of natural rubber. Due to the special properties of the material of the sealing sleeve 430, it can seal the trapezoidal tank platform 410 when the equipment is working. The setting of the sealing sleeve 430 also prevents ammonia from leaking from the feed pipe 420 during ammonia mixing. The gas guide pipe 340 is connected to the disc tube 500. The mounting platform 352 and the support plate 310 are slidably connected. The length of the mounting platform 352 is the same as the width of the inner wall of the support plate 310, and the filter hole 353 penetrates the mounting platform 352, so that the gas injected from the gas guide pipe 340 can be directly introduced into the disc tube 500 through the support plate 310.

[0024] Working principle: When the equipment is needed, the mounting plate 351 is removed by turning the screw 360. After the mounting plate 351 is removed, the worker places the medicine with cooling function on the placement platform 352, turns the screw 360 again to reset the mounting plate 351, and the drive motor 710 drives the drive shaft 720 to drive the stirring rod 730 to stir the ammonia water. The volatilized ammonia gas will be given downward pressure in the closed environment of the trapezoidal tank platform 410, forcing the ammonia water into the gas guide pipe 340 and discharged from the equipment through the discharge pipe 220.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
