Description

Technical Field

[0001] The utility model relates to the technical field of storage tanks, in particular to a material storage tank for chloroacetic acid production. Background Art

[0002] Chloroacetic acid, as an organic acid, is usually stored in liquid form. During storage, the main consideration is to keep it stable under appropriate temperature and ventilation conditions. The container for storing chloroacetic acid needs to have good sealing properties to prevent the loss of chloroacetic acid vapor or the entry of outside air.

[0003] However, when encountering high temperature conditions, the chloroacetic acid stored in the tank will be heated and accumulate at the top of the tank in the form of chloroacetic acid vapor. While increasing the pressure in the tank, it is also prone to cause accidents such as leakage. At the same time, chloroacetic acid vapor is toxic and harmful to the human body.

[0004] To solve the above problems, we proposed a material storage tank for chloroacetic acid production. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 3 A material storage tank for chloroacetic acid production, comprising a tank body 1, a horizontally arranged pressure-conducting pipe 2 is fixedly connected to the top of the tank body 1, a pipe plug for closing the pipe opening is fixedly connected to the end of the pressure-conducting pipe 2 away from the tank body 1, a spring 3 located inside the pressure-conducting pipe 2 is fixedly connected to the pipe plug, a slide bar 4 is slidably arranged in the pressure-conducting pipe 2 and one end of the slide bar 4 is fixedly connected to the spring 3, two fixing rings 5 ​​are fixedly arranged in the pressure-conducting pipe 2, and the slide bar 4 is located between the two fixing rings 5;

[0021] An air guide hole is provided in the middle of the slide bar 4 and is horizontally and vertically connected to the slide bar 4. Two air guide tubes 6 are fixedly connected to the outer wall of the pressure guiding tube 2 near the top center of the tank body 1. One end of the two air guide tubes 6 away from the pressure guiding tube 2 is fixedly connected to the tank body 1. The two pressure guiding tubes 2 are respectively located on both sides of the air guide hole and between the two fixing rings 5. Two air guide tubes 27 are fixedly connected to the outer wall of the pressure guiding tube 2 away from the air guide tube 6. The two air guide tubes 27 correspond to the two air guide tubes 6 respectively. When the slide bar 4 moves left and right, the fixing rings 5 ​​at the left and right ends will limit the slide bar 4, so that the air guide hole located in the middle of the slide bar 4 can only move between the ports where the two air guide tubes 6 are connected to the pressure guiding tube 2. The two air guide tubes 27 are respectively connected to the two air guide tubes 6. The tubes 27 are all set at right angles and their bottom ends are vertically parallel to the outer wall of the tank body 1. The ports where the two air guide tubes 1 6 are connected to the pressure guide tube 2 are at the same height and have the same port diameter as the ports where the two air guide tubes 2 7 are connected to the pressure guide tube 2. An air guide box 8 is fixedly connected to the outer wall of the tank body 1. The bottom ends of the two air guide tubes 2 7 are commonly connected to the air guide box 8. A sliding tube 9 is fixedly set on the air guide box 8. Fixed rings 2 10 are respectively fixedly connected to both ends of the sliding tube 9. A slider 11 located between the two fixed rings 2 10 is slidably set in the sliding tube 9. The outer wall of the slider 11 fits the inner wall of the sliding tube 9. The left and right ends of the slider 11 are both set in a conical shape and the port diameter is smaller than the inner diameter of the fixed ring 2 10.

[0022] When the temperature rises, the chloroacetic acid in the tank body 1 volatilizes to produce toxic gas. At this time, the pressure inside the tank body 1 is too high, causing the gas to push the slide bar 4 to move through the pressure-conducting tube 2 at the top of the tank body 1. The air guide hole located in the middle of the slide bar 4 moves left with the slide bar 4 to between the air guide tube 1 6 and the air guide tube 2 7 located at the left end of the pressure-conducting tube 2. At this time, the excess gas in the tank body 1 will be introduced into the air guide box 8 through the air guide tube 1 6, the air guide hole and the air guide tube 2 7. At this time, the slide tube 9 located on the air guide box 8, when the gas is injected into the air guide box 8, the slider 11 located in the slide tube 9 will move to the end away from the air guide box 8, so that the pressure in the air guide box 8 is in a stable state.

[0023] When the temperature is low and the pressure in the tank body 1 decreases, the slide bar 4 will move to the left in the pressure guiding tube 2 and be located between the air guiding tube 1 6 and the air guiding tube 2 7 fixedly connected at the left end of the pressure guiding tube 2. At this time, the gas in the air guiding box 8 will flow into the tank body 1, and the slider 11 located in the slide tube 9 will approach the air guiding box 8, so that the air pressure in the air guiding box 8 is in a stable state.

[0024] A material delivery pipe 12 is fixedly connected to the top of the tank body 1, and a sealing cover 13 is rotatably connected to the material delivery pipe 12. A material guide pipe 14 close to the lower end of the tank body 1 is fixedly connected to the outer wall of the tank body 1, and three rotationally symmetrical supporting legs 16 are fixedly connected to the bottom end of the tank body 1. A temperature gauge 15 located directly above the material guide pipe 14 is fixedly connected to the outer wall of the tank body 1.

[0025] 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 principles of the present invention should be included in the protection scope of the present invention.
