Description

Technical Field

[0001] The utility model relates to the technical field of hydrochloric acid storage, in particular to a hydrochloric acid feeding device. Background Art

[0002] Hydrochloric acid, whose chemical name is hydrogen chloride, is actually an aqueous solution of HCl. It is a monobasic inorganic strong acid. It is a colorless and transparent liquid with a strong pungent odor and is highly corrosive. It has a wide range of industrial uses and can be used as an industrial cleaning agent and neutralizing agent. At the same time, hydrochloric acid is also the raw material for the production reaction of polyaluminum chloride.

[0003] Since hydrochloric acid is volatile and has a pungent odor, hydrochloric acid needs to be stored in a sealed container. In the production of polyaluminium chloride, hydrochloric acid is discharged through a pipeline and fed to be mixed with calcium aluminate powder and water. Existing devices for storing and feeding hydrochloric acid are provided with two structures, a discharge pipe and a feed pipe, one for discharging hydrochloric acid and the other for feeding hydrochloric acid, with division of labour. The discharge pipe is arranged at the bottom of the storage and feeding device, and gravity can be used to assist the feeding and discharge of hydrochloric acid. However, according to this structural composition mode, after the discharge pipe of the storage and feeding device is used, a small amount of hydrochloric acid will remain inside the discharge pipe and flow out along the wall to the outside, causing environmental pollution, which is very inconvenient. Utility Model Content

[0004] Based on the above description, the utility model provides a hydrochloric acid feeding device to solve the problem that after the discharge pipe of the existing hydrochloric acid storage and feeding device is used, a small amount of hydrochloric acid inside will flow out along the wall to the outside, causing environmental pollution.

[0005] The utility model solves the above-mentioned technical problems with a technical solution as follows: a hydrochloric acid feeding device, comprising a storage tank, wherein a spacer ring for separating spaces is installed inside the storage tank, a booster device extending to the inner side of the spacer ring is installed at one end of the storage tank, and a pipeline assembly penetrating the spacer ring and extending to the other end of the inner wall of the storage tank is installed at one end of the storage tank.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, an air inlet hole and a tank mouth are provided at one end of the storage tank, and the tank mouth is located in the center of one end of the storage tank. A first sealing baffle ring extending to the inner side of the tank mouth is installed in the center of one end of the storage tank, and a sealing gasket is installed between the outer side of the first sealing baffle ring and the inner side of the tank mouth.

[0008] Furthermore, the spacer ring is installed on one end of the inner side of the storage tank close to the tank mouth, the inner side of one end of the spacer ring is tubular and extends toward the tank mouth, and is perpendicular to the two ends of the storage tank, and the inner wall of the storage tank is arc-shaped at one end away from the tank mouth.

[0009] Furthermore, the pipeline assembly consists of an outer pipeline and a valve, the outer pipeline is installed in the first sealing baffle ring, one end of the outer pipeline extends to the outside of the storage tank, the other end of the outer pipeline passes through the spacer ring and extends to the arc-shaped end of the storage tank, and the valve is installed at one end of the outer pipeline away from the storage tank.

[0010] Furthermore, the boosting device is composed of a boosting pump and an air pipe, the boosting pump is installed at one end of the storage tank close to the spacer ring, the air pipe is installed at one end of the boosting pump, the air pipe passes through the air inlet hole, and extends to the inside of the storage tank.

[0011] Furthermore, a second sealing baffle ring inserted between the air pipe and the air inlet is installed at one end of the storage tank close to the spacer ring, and a switch pipe fitting is installed on the surface of the storage tank and on one side of the spacer ring close to the tank mouth.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0013] The utility model uses a booster pump and a spacer ring, in conjunction with an external pipe and a valve. The spacer ring reserves a portion of space inside the storage tank for filling with air. The external pipe is inserted into the hydrochloric acid to form a seal. When gas is continuously filled into the storage tank, the hydrochloric acid can only flow from the bottom of the external pipe to the end where the valve is opened due to pressure, and in conjunction with the external pipe, the purpose of feeding and discharging is completed. Restricted by the vertical arrangement of the external pipe and the valve, after the valve is used, a small amount of hydrochloric acid that is not discharged inside can only be retained in the valve or reflux along the external pipe, thereby ensuring the safety of the use of hydrochloric acid and preventing the hydrochloric acid from leaking to the outside to cause environmental pollution. When the external pipe is used alone, it can also be used as a path for adding hydrochloric acid to the storage tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0021] See also Figure 1-3 The utility model is a hydrochloric acid feeding device, comprising a storage tank 1, a partition ring 5 for separating spaces is installed inside the storage tank 1, a booster device extending to the inner side of the partition ring 5 is installed at one end of the storage tank 1, and a pipeline component penetrating the partition ring 5 and extending to the other end of the inner wall of the storage tank 1 is installed at one end of the storage tank 1.

[0022] See also Figure 1 An air inlet 11 and a tank mouth 12 are provided at one end of the storage tank 1. The tank mouth 12 is located at the center of one end of the storage tank 1. A first sealing baffle ring 2 extending to the inner side of the tank mouth 12 is installed at the center of one end of the storage tank 1. A sealing gasket 21 is installed between the outer side of the first sealing baffle ring 2 and the inner side of the tank mouth 12. The first sealing baffle ring 2 is installed in the tank mouth 12 in conjunction with the sealing gasket 21, which can not only fix the external pipeline 3, but also ensure the sealing of the external pipeline 3 after installation to prevent hydrochloric acid leakage.

[0023] See also Figure 2 The spacer ring 5 is installed at one end of the inner side of the storage tank 1 close to the tank mouth 12. The inner side of one end of the spacer ring 5 is tubular and extends toward the tank mouth 12, and is perpendicular to the two ends of the storage tank 1. The setting of the spacer ring 5 isolates a space for pressurized gas filling in the storage tank 1, which can be filled with pressurized gas. The end of the inner wall of the storage tank 1 away from the tank mouth 12 is arc-shaped. The arc-shaped end of the inner wall of the storage tank 1 is arranged, which facilitates the stored hydrochloric acid to enter the outer pipe 3 along the bottom of the outer pipe 3 after being affected by the pressure, and be discharged from the storage tank 1.

[0024] See also Figure 2The pipeline assembly consists of an outer pipeline 3 and a valve 31. The outer pipeline 3 is installed in the first sealing retaining ring 2. One end of the outer pipeline 3 extends to the outside of the storage tank 1. The other end of the outer pipeline 3 passes through the spacer ring 5 and extends to the arc-shaped end of the storage tank 1. The bottom of the outer pipeline 3 is inserted into the hydrochloric acid in the storage tank 1 to form a seal. The valve 31 is installed at the end of the outer pipeline 3 away from the storage tank 1. The valve 31 is used to control the opening and closing of the outer pipeline 3. It can also be connected to an external pipeline to cooperate in the transportation of hydrochloric acid after it is discharged from the storage tank 1. A gap is left between the spacer ring 5 and the outer pipeline 3, and the pressurized gas filled in the spacer ring 5 can flow to the spacer ring 5. On the other side, pressure is applied to the stored hydrochloric acid, and the valve 31 is opened for use. When more and more gas is in the storage tank 1, the stored hydrochloric acid can only flow into the outer pipe 3 and be discharged from the storage tank 1 due to pressure. The feeding and discharge are completed in combination with the external pipe. Due to the vertical arrangement of the outer pipe 3 and the valve 31, after the valve 31 is used, a small amount of hydrochloric acid that has not been discharged inside can only be retained in the valve 31 or reflux along the outer pipe 3, thereby ensuring the safety of the use of hydrochloric acid and preventing the hydrochloric acid from leaking to the outside and causing environmental pollution. The booster pump 4 is not activated. When the outer pipe 3 is used alone, the outer pipe 3 can be used for adding hydrochloric acid to the storage tank 1.

[0025] See also Figure 1 The boosting device is composed of a boosting pump 4 and an air pipe 41. The boosting pump 4 is installed at one end of the storage tank 1 near the spacer ring 5. The boosting pump 4 is a gas boosting pump. The air pipe 41 is installed at one end of the boosting pump 4. The air pipe 41 passes through the air inlet 11 and extends to the inside of the storage tank 1. A second sealing baffle ring 42 inserted between the air pipe 41 and the air inlet 11 is installed at one end of the storage tank 1 near the spacer ring 5. A switch pipe 6 is installed on the surface of the storage tank 1 and on the side of the spacer ring 5 near the tank mouth 12. The switch pipe 6 can be controlled to be on and off. After the boosting of the boosting pump 4 and the discharge of the external pipeline 3 are completed, the switch pipe 6 can be opened to allow the outside air to flow between the storage tank 1 and the storage tank 1 to restore the pressure state in the storage tank 1. When the switch pipe 6 is closed, it does not affect the sealing of the storage tank 1.

[0026] When it is necessary to extract hydrochloric acid from the storage tank 1 for feeding, first install the external pipe on the outside of the valve 31, open the valve 31, and then start the booster pump 4. The booster pump 4 fills the storage tank 1 with pressurized gas. Since the bottom end of the external pipe 3 is inserted into the hydrochloric acid inside the storage tank 1 and is in a sealed state, and the gas in the storage tank 1 is increasing, the gas can pressurize the hydrochloric acid in the storage tank 1, so that it passes through the bottom of the external pipe 3, flows vertically upward, and is discharged into the external pipe along the valve 31, completing the feeding and discharge.
