Acid storage tank

Abstract

The invention provides an acid storage tank which is divided into an upper tank and a lower tank which are mutually independent, openings are formed in the upper parts of the upper tank and the lower tank and communicated with an acid adding pipe, an opening is formed in the lower part of the upper tank and communicated with an acid discharging pipe, a valve is mounted on the acid discharging pipe, and an acid conveying pipe is further arranged between the lower part of the lower tank and the upper part of the upper tank. And a corrosion-resistant pump and a valve are mounted on the acid feeding pipe. Due to the fact that the position of the upper tank is high, the acid liquor can be conveyed to a production site through the pipeline by means of the gravity of the acid liquor, the situation that the acid liquor is conveyed outwards through a corrosion-resistant pump and then the acid liquor in the lower tank needs to be pumped into the upper tank through the corrosion-resistant pump is not needed, the pumping distance is very short, and the production cost is greatly saved. The mode of conveying the acid liquor by means of self-gravity has the advantages of convenience, rapidness and safety, and more energy consumption is saved.

Description

Technical Field

[0001] The present invention relates to the technical field of acid storage and transportation, and particularly relates to an acid storage tank. Background Art

[0002] The main functions of the acid storage tank are to store and transport liquid sulfuric acid and hydrochloric acid. The existing acid storage tanks on the market have a simple structure, and basically all have only one acid storage chamber. When in use, a pump is required to transport the acid liquid out. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an acid storage tank that can transport acid liquid out through a pipeline by relying on its own gravity.

[0004] To solve the above technical problem, the solution of the present invention is: an acid storage tank, which is divided into an upper tank and a lower tank that are independent of each other. The upper parts of the upper tank and the lower tank are both provided with openings communicating with an acid adding pipe. The lower part of the upper tank is provided with an opening communicating with an acid discharging pipe, and a valve is installed on the acid discharging pipe. A acid transporting pipe is also provided between the lower part of the lower tank and the upper part of the upper tank, and a corrosion-resistant pump and a valve are installed on the acid transporting pipe.

[0005] The working principle and process of the above technical solution are as follows: 1) Inject the acid liquid in the tank truck into the upper tank and the lower tank through the acid adding pipe; 2) When the acid liquid needs to be used, open the valve on the acid discharging pipe, and the acid liquid in the upper tank can be transported to the production site by its own gravity; 3) When the acid liquid in the upper tank gradually decreases, the self-gravity of the acid liquid will become smaller, and the transportation pressure will also decrease accordingly. At this time, the corrosion-resistant pump and the valve on the acid transporting pipe can be opened to pump the acid liquid in the lower tank into the upper tank.

[0006] Further, the pipe body of the acid discharging pipe is bent downward.

[0007] Further, in order to balance the pressure in the tank body, the upper parts of the upper tank and the lower tank are both provided with openings communicating with an exhaust pipe.

[0008] Further, in order to facilitate observing the amount of acid liquid in the tank body, the upper tank and the lower tank are both provided with liquid level gauges.

[0009] Among them, two lifting lugs are provided outside the upper tank, so that the acid storage tank can be easily moved.

[0010] The beneficial effects of the present invention are as follows: Since the upper tank is located at a relatively high position, the self-gravity of the acid solution can be utilized to transport the acid solution to the production site through a pipeline, without the need to use a corrosion-resistant pump for external transportation. As for subsequently pumping the acid solution in the lower tank to the upper tank by a corrosion-resistant pump, the pumping distance is also very short. Therefore, the production cost is greatly saved. This method of transporting acid solution by self-gravity has the advantages of convenience, speed, and safety, and is more energy-saving.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0012] In order to make the objectives, technical solutions and advantages of the invention more clear and understandable, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not limited to the present invention.

[0013] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0014] As Figure 1 shown, a preferred embodiment of the present invention is: an acid storage tank, which is divided into an upper tank 1 and a lower tank 2 that are independent of each other. The upper parts of the upper tank 1 and the lower tank 2 are both provided with openings communicating with the acid addition pipe 3. The lower part of the upper tank 1 is provided with an opening communicating with the acid discharge pipe 4, and a valve is installed on the acid discharge pipe 4. A acid delivery pipe 5 is also provided between the lower part of the lower tank and the upper part of the upper tank. A corrosion-resistant pump 6 and a valve are installed on the acid delivery pipe 5; in order to balance the pressure in the tank body, the upper parts of the upper tank 1 and the lower tank 2 are both provided with openings communicating with the exhaust pipe 7; in order to facilitate observing the amount of acid solution in the tank body, liquid level gauges 8 are provided on both the upper tank and the lower tank; two lifting lugs 9 are provided outside the upper tank, so that the acid storage tank can be easily moved.

[0015] The working principle and process of the above technical solution are as follows: 1) Inject the acid solution in the tank truck into the upper tank 1 and the lower tank 2 through the acid addition pipe 3; 2) When it is necessary to use the acid solution, open the valve on the acid discharge pipe 4, and the acid solution in the upper tank 1 can be transported to the production site by self-gravity. 3) After the acid solution in the upper tank 1 gradually decreases, the self-gravity of the acid solution will become smaller, and the conveying pressure will also decrease accordingly. At this time, the corrosion-resistant pump 6 and the valve on the acid supply pipe 5 can be opened to pump the acid solution in the lower tank 2 into the upper tank.

[0016] In the above technical solution, since the position of the upper tank 1 is relatively high, the acid solution can be transported to the production site through the pipeline by using the self-gravity of the acid solution without the need to rely on a corrosion-resistant pump for external transportation. As for the subsequent need to pump the acid solution in the lower tank into the upper tank by a corrosion-resistant pump, the pumping distance is also very short. Therefore, the production cost is greatly saved. This method of transporting the acid solution by self-gravity has the advantages of convenience, speed, and safety, and is more energy-saving.

[0017] The above embodiments are the preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious substitution without departing from the concept of the present technical solution is within the scope of the present invention patent.

Those of ordinary skill in the art should be aware that these omitted elements may also constitute the content of the present invention.
