Description

Technical Field

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

[0002] Chemical storage tanks are special equipment used to store liquids or gases such as chemicals, oil, and natural gas. These tanks are usually made of steel or fiberglass, and have the characteristics of high strength, corrosion resistance, and good sealing.

[0003] When a storage tank is used to store chemical materials, the chemical substances in the storage tank may release heat due to certain reactions, causing the temperature to rise, thereby increasing the gas pressure. In summer, when the temperature is high, the gas in the storage tank will also expand, thereby increasing the pressure. Traditional storage tanks are usually simple tank structures and lack the necessary protective structures. Once the pressure in the tank is too high and cannot be released, it may cause explosions and other dangers. To this end, we propose a chemical material storage tank to solve the above problems. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the utility model provides a chemical material storage tank, which has the advantages of being able to prevent the gas in the storage tank from expanding and causing an explosion, and solves the above-mentioned technical problems.

[0006] (II) Technical solution

[0008] Preferably, the spring is arranged inside the air outlet pipe, and the bottom end of the spring contacts the piston plate.

[0009] Through the above technical solution, chemical raw materials are stored in a tank body. If the chemical raw materials undergo an exothermic reaction and cause gas expansion, the gas will enter the sleeve and then enter the cylinder body to generate an extrusion force on the piston plate. The piston plate then compresses the spring and rises. When the height of the piston plate in the outlet pipe is higher than the position of the air hole, the expanded gas in the tank body will leak out from the air hole, thus avoiding the tank body from being in a high-pressure state all the time, thereby avoiding the risk of explosion.

[0010] Preferably, a clamp is provided on the outer surface of the collecting bottle, and the clamp is fixed to one end of the tank body by bolts.

[0011] Through the above technical solution, the gas leaked into the cylinder will flow into the ventilation pipe through the cone tube, and then enter the collection bottle for temporary storage. At the same time, because the gas will pass through the three-way head, the gas alarm can detect it and sound an alarm to remind the staff, who will then make professional handling to avoid accidents.

[0012] Preferably, a feed pipe is provided on the top of the tank body, and the top end of the feed pipe is connected to the end cover by bolts.

[0013] Through the above technical solution, the chemical material can be injected into the tank body by opening the end cover, and then the end cover is installed. A sealing ring is provided at the connection between the end cover and the feed pipe to ensure the sealing performance.

[0014] Preferably, a manhole pipe is provided on one side of the tank body, a sealing door is hinged on the manhole, the outer surface of the manhole pipe is rotatably connected to a locking bolt, and the outer surface of the locking bolt is threadedly connected to a knob.

[0015] With the above technical solution, when it is necessary to clean the inside of the tank, it is only necessary to turn the knob counterclockwise so that it and the locking bolt no longer lock the sealing door, making it convenient to open the sealing door and enter the inside of the tank to clean it.

[0016] Preferably, two lifting rings are fixedly connected to the top of the tank body, a ladder is welded to the outer surface of the tank body, and one end of the tank body is fixedly connected to a discharge pipe, and a valve is installed at one end of the discharge pipe.

[0017] Through the above technical solution, the entire storage tank can be easily hoisted through two lifting rings, and the provided ladder is convenient for the staff to climb to the top of the tank body and open the end cover. By opening the valve, the discharge pipe can discharge the stored chemical materials.

[0018] Compared with the prior art, the utility model provides a chemical material storage tank, which has the following beneficial effects:

[0019] The utility model discloses that when the chemical material has an exothermic reaction and causes the gas to expand, the gas will enter the sleeve and then enter the cylinder body to generate an extrusion force on the piston plate, and the piston plate will then compress the spring and rise. When the height of the piston plate in the air outlet pipe is higher than the position of the air hole, the expanded gas in the tank body will leak out from the air hole and enter the cylinder body, then flow into the ventilation pipe through the cone tube, and finally enter the collection bottle for temporary storage. At the same time, because the gas will pass through the three-way head, the gas alarm can detect it and sound an alarm to remind the staff. The overall structure prevents the tank body from being in a high-pressure state all the time, which is prone to explosion accidents. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Specifically, the spring 9 is arranged inside the air outlet pipe 4, and the bottom end of the spring 9 contacts the piston plate 7. The advantage is that when the chemical raw materials are stored in the tank body 1, if the chemical raw materials have an exothermic reaction and cause the gas to expand, the gas will enter the sleeve 2, and then enter the cylinder body 3 to generate a squeezing force on the piston plate 7, and the piston plate 7 will then compress the spring 9 and rise. When the height of the piston plate 7 in the air outlet pipe 4 is higher than the position of the air hole 5, the expanded gas in the tank body 1 will leak out from the air hole 5, thereby avoiding the tank body 1 from being in a high-pressure state all the time, thereby avoiding the risk of explosion.

[0029] Specifically, a clamp 15 is provided on the outer surface of the collecting bottle 13, and the clamp 15 is fixed to one end of the tank body 1 by bolts. The advantage is that the gas leaking into the cylinder body 3 will flow into the vent pipe 11 through the cone 10, and then enter the collecting bottle 13 for temporary storage.

[0031] Specifically, a manhole pipe 18 is provided on one side of the tank body 1, and a sealing door 19 is hinged on the manhole. The outer surface of the manhole pipe 18 is rotatably connected to a locking bolt 20, and the outer surface of the locking bolt 20 is threadedly connected to a knob 21.

The piston plate 7 then compresses the spring 9 and rises. When the height of the piston plate 7 in the air outlet pipe 4 is higher than the position of the air hole 5, the expanded gas in the tank body 1 will leak out from the air hole 5 and enter the cylinder body 3, and then flow into the ventilation pipe 11 through the cone 10, and finally enter the collection bottle 13 for temporary storage. At the same time, because the gas will pass through the three-way head 12, the gas alarm 14 can detect it and sound an alarm to remind the staff. The overall structure prevents the tank body 1 from being in a high-pressure state and easily causing an explosion accident.
