Description

Technical Field

The utility model provides a bottom plate inclined relative to the tank bottom at the bottom of the tank, and the lowest point of the bottom plate is located below the opening. The liquid in the tank is affected by the slope, and when the liquid is discharged, it will all gather below the opening, so that the liquid in the tank can be completely discharged.

Long-term use will cause a large amount of H2SiO3 precipitation to remain at the bottom of the sodium silicate storage tank, affecting the quality of the sodium silicate in the storage tank.

[0023] 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.

[0024] See also Figure 1 and 3 -4, the utility model is a liquid sodium silicate storage tank, including a tank body 10 storing liquid sodium silicate therein, the top of the tank body 10 is connected to an air filter device 2, the air filter device 2 is filled with an absorbent 26 for treating the air passing through the inside to remove the carbon dioxide therein; thereby, when in use, when the liquid sodium silicate is discharged through the discharge pipe 12 connected to the bottom of the tank body 10, in order to keep the pressure inside and outside the tank body 10 the same, the ambient air enters the tank body 10 after being acted upon by the air filter device 2.

[0025] Of course, in some possible implementations, a gas storage tank for storing nitrogen or oxygen or the like can be used and connected to the top of the tank body 10. When liquid sodium silicate needs to be discharged, the gas storage tank is controlled to pass the stored gas into the tank body 10, thereby maintaining the same pressure inside and outside the tank body 10.

[0026] Specifically, in this application, Figure 2 and 5The air filter device 2 is a storage barrel, which stores an absorbent 26 for absorbing carbon dioxide in the air, and an air inlet pipe 24 is arranged through the top of the storage barrel, the outlet end of the air inlet pipe 24 is inserted into the absorbent 26, and the top of the storage barrel is connected to an exhaust pipe 23, and the exhaust pipe 23 is connected to the top of the tank body 10. When in use, ambient air enters the storage barrel through the air inlet pipe 24 and is directly discharged into the absorbent 26 from the outlet end of the air inlet pipe 24. At this time, the ambient air is fully in contact with the absorbent 26, and components such as sulfur dioxide and carbon dioxide in the air are absorbed at this time. The absorbed ambient air is then passed into the tank body 10 through the top of the tank body 10.

[0027] Of course, it can be known that, in a specific embodiment, the absorbent 26 is a calcium hydroxide solution. At this time, when the air enters below the liquid surface through the air inlet pipe 24 and emerges from the liquid surface, the airflow easily carries away part of the calcium hydroxide solution. These calcium hydroxide solutions easily enter the tank body 10 along with the airflow and affect the quality of the liquid sodium silicate stored in the tank body 10. Based on this, it is necessary to set a filter bin 3 between the air filter device 2 and the tank body 10, and use the filter bin 3 to dry the air entering the tank body 10, thereby preventing the airflow from carrying the calcium hydroxide solution components into the tank body 10.

[0028] At the same time, when the absorbent 26 is selected from calcium hydroxide solution, air enters the liquid surface through the air inlet pipe 24 and easily forms bubbles when the liquid surface emerges. After the bubbles burst, part of the calcium hydroxide solution will splash to the bottom end of the exhaust pipe 23, such as Figure 5-7 , thereby causing pollution to the inside of the bottom end of the exhaust pipe 23, and then to the anti-splash mechanism 27 on the top side of the storage barrel, the anti-splash mechanism 27 includes a bottom plate 270, and a convex tube A271 and a convex tube B272 arranged on the upper surface of the bottom plate 270, the top of the convex tube A271 is higher than the top of the convex tube B272, the top of the convex tube A271 is connected to a "cross"-shaped connecting frame 274, the surrounding side of the "cross"-shaped connecting frame 274 is connected to the inner side wall of a tube body 273, and the top of the tube body 273 is provided with a mounting flange 275; during installation, the mounting flange 275 is fixed to the air inlet pipe 24 on the top side of the storage barrel by glue or screws.

[0029] Specifically, one end of the filter chamber 3 is connected to the air inlet joint 14 through the pipeline A31, and the other end of the filter chamber 3 is connected to the pipeline B28, and the filter chamber 3 is filled with activated carbon granular desiccant.

[0030] It can be understood that in the relevant embodiment, in order to facilitate the control of the discharge and addition of the absorbent 26 in the air filter device 2, a drain pipe 21 is provided at the bottom of the storage barrel, and a valve A22 is installed on the drain pipe 21; a feeding port is provided at the top of the air filter device 2, and a sealing cover 25 is provided on the feeding port.

[0031] Similarly, a valve B13 is installed on the discharge pipe 12, and the tank body 10 is installed on a storage tank bracket 1. A feeding port is provided on the top of the tank body 10, and a top cover 11 is installed at the feeding port in a sealing manner, and an air inlet joint 14 is connected to the top cover 11; a support plate 30 is welded to one side of the storage tank bracket 1, and a filter bin 3 is installed on the support plate 30. One end of the filter bin 3 is connected to the air inlet joint 14 through a pipe A31, and the other end of the filter bin 3 is connected to the air inlet joint 14 through a pipe A31, and the other end of the filter bin 3 is connected to the pipe B28.

[0032] It should be noted that in the present application, in addition to calcium hydroxide solution, the absorbent 26 may also be alkaline solutions such as sodium hydroxide solution and potassium hydroxide solution that can absorb carbon dioxide, and solid sodium hydroxide may also be needed; at the same time, the activated carbon granule desiccant may also be replaced by anhydrous copper sulfate desiccant, solid calcium oxide and other desiccants.

The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model.
