Description

Technical Field

[0001] This application relates to the technical field of storage devices, and particularly to a hydrochloric acid storage tank. Background Art

[0002] Hydrochloric acid is a mixture composed of hydrochloric acid and nitric acid, chemically known as an aqueous solution of hydrogen chloride. It is a colorless and transparent liquid with a strong pungent odor and high corrosiveness. Hydrochloric acid is generally stored in a hydrochloric acid storage tank. Concentrated hydrochloric acid has extremely strong volatility. When the container of concentrated hydrochloric acid is opened, hydrogen chloride gas will volatilize and combine with water vapor in the air to produce hydrochloric acid droplets, forming acid mist. In production and daily life, hydrochloric acid is applied in many aspects, such as pickling steel, household cleaning solution, producing gelatin, descaling reagent, leather processing, etc.

[0003] Referring to the Chinese patent document with the reference number CN109160041B and the name of a hydrochloric acid storage tank, it includes a storage tank. On both sides of the liquid inlet of the storage tank, air storage chambers are symmetrically arranged. The air storage chambers are used to store the gas in the storage tank. On the side wall of the liquid inlet, buffer bags are symmetrically arranged. The buffer bags are used to buffer the hydrochloric acid at the liquid inlet. Air bags are arranged at intervals in the buffer bags. A spiral plastic pipe is arranged in the storage tank. The plastic pipe is used to transport the hydrochloric acid at the feed ring opening to the bottom of the storage tank. A set of exhaust units are arranged on the inner wall of the storage tank. When in use, the hydrochloric acid liquid is aligned with the liquid inlet. The hydrochloric acid contacts the buffer belt and squeezes the air bags arranged on both sides of the buffer belt. The hydrochloric acid flows along the buffer belt and the plastic pipe into the bottom of the storage tank. When the hydrochloric acid enters the storage tank, the gas in the upper part of the storage tank is discharged from the exhaust unit. The setting of the buffer bags and air bags can make the liquid inlet of the buffer bags larger while preventing hydrochloric acid from splashing, accelerating the speed of hydrochloric acid entering the storage tank, preventing hydrochloric acid from splashing, protecting the safe working environment of the staff, and at the same time avoiding the volatilization of the hydrochloric acid solution.

[0004] Referring to the above technical solution, when hydrochloric acid enters the storage tank, the amount of hydrochloric acid entering the storage tank is proportional to the discharged gas. When hydrochloric acid enters the bottom of the storage tank, the hydrochloric acid is easy to contact the gas at the bottom of the storage tank. When the hydrochloric acid is stationary in the storage tank, the liquid on the surface of the hydrochloric acid still contacts the surface of the gas. In the process of contact between hydrochloric acid and gas, it is easy to cause the volatilization of hydrochloric acid. Summary of the Invention

[0005] In view of this, this application provides a hydrochloric acid storage tank, which is mainly used to solve the problem of reducing the contact between hydrochloric acid and gas.

[0006] To solve the above technical problems, the present application provides a hydrochloric acid storage tank, which includes a cylindrical upper storage tank and a lower storage tank. An inlet ring opening is provided on the upper storage tank, and an outlet ring opening is provided on the lower storage tank. An exhaust assembly is provided at the inlet ring opening. A cylindrical airbag is installed at the joint of the upper storage tank and the lower storage tank. An airbag infusion tube is provided on the cylindrical airbag. The airbag infusion tube is used to convey hydrochloric acid liquid from the inlet ring opening to the bottom of the lower storage tank. The cylindrical airbag and the airbag infusion tube are coaxially arranged. An airbag liquid outlet communicating with the airbag infusion tube is opened on the cylindrical airbag. A wrinkled opening is provided in the middle of the airbag infusion tube.

[0007] By adopting the above technical solution, the hydrochloric acid at the inlet ring opening can directly reach the bottom of the lower storage tank through the airbag infusion tube, which can prevent hydrochloric acid from splashing. The cylindrical airbag can reduce the contact between hydrochloric acid and gas, prevent hydrochloric acid from contacting too much gas, and reduce the evaporation amount of hydrochloric acid. While the hydrochloric acid inside the lower storage tank is continuously increasing, the cylindrical airbag can be turned up, which can ensure the lower storage tank to carry the hydrochloric acid. The exhaust assembly can discharge the gas from the inside of the upper storage tank, so that the amount of discharged gas is balanced with the amount of hydrochloric acid entering.

[0008] Optionally, two semi-circular clamping plate rings are provided on the inlet ring opening. A flange is threadedly connected to the semi-circular clamping plate ring. The flange, the semi-circular clamping plate ring and the inlet ring opening are coaxially arranged.

[0009] By adopting the above technical solution, the flange facilitates the connection of the device to other components.

[0010] Optionally, the exhaust assembly includes exhaust hollow columns provided on the semi-circular clamping plate ring. Two exhaust hollow columns are provided on each semi-circular clamping plate ring and are symmetrically arranged. The exhaust hollow columns penetrate through the inner and outer side walls of the clamping plate and are provided on the inlet opening.

[0011] Optionally, a rotating shaft is rotatably connected to both groups of symmetric exhaust hollow columns. A connecting plate is also fixedly installed on the rotating shaft. A return spring is provided between the connecting plate and the inlet ring opening. A clamping plate for clamping the airbag infusion tube is fixedly installed on the rotating shaft.

[0012] By adopting the above technical solution, under the action of the elastic force, the return spring can drive the clamping plates on both sides to clamp the airbag infusion tube, making the airbag infusion tube flat, which can prevent too much air from entering the airbag infusion tube and contacting the hydrochloric acid.

[0013] Optionally, the exhaust assembly further includes an exhaust valve opened on the rotating shaft and an exhaust hole opened on the exhaust hollow column. The exhaust hole is opened on three of the exhaust hollow columns.

[0014] By adopting the above technical solution, while hydrochloric acid continuously flows through the airbag infusion tube, the airbag infusion tube clamped by two splints can be transformed from a flat shape to a circular ring shape, which can drive the rotation of the rotating shaft, making the exhaust valve correspond to the exhaust hole. While the hydrochloric acid enters the lower storage tank, the exhaust valve can extract the gas in the upper storage tank and discharge it from the exhaust hole.

[0015] Optionally, an air inlet hole is provided on the exhaust hollow column. The air inlet hole is provided on one of the exhaust hollow columns, and an air inlet valve is arranged on the exhaust hollow column.

[0016] By adopting the above technical solution, when the hydrochloric acid is discharged, the air inlet valve corresponds to the air inlet hole, and the air inlet valve sucks the external gas into the upper storage tank through the air inlet hole, which can ensure that the discharge amount of hydrochloric acid and the intake amount of gas are balanced.

[0017] Optionally, a twist cap is arranged on the discharge ring opening, a telescopic spring is installed on the twist cap, and a piston is arranged on the telescopic spring.

[0018] By adopting the above technical solution, the telescopic spring can drive the piston to contact the inner wall of the discharge ring opening, strengthening the sealing performance of the discharge ring opening.

[0019] Optionally, an airbag liquid inlet located at the feed ring opening is connected to the airbag infusion tube, and a compression ring for fixing the airbag liquid inlet is installed on the feed ring opening.

[0020] By adopting the above technical solution, the compression ring facilitates the pressing and fixing of the airbag liquid inlet, and is convenient for disassembly and installation under the connection of the flange and the semi-circular splint ring.

[0021] Optionally, connecting threads are arranged on the inner wall of the compression ring.

[0022] By adopting the above technical solution, the connecting threads facilitate the connection of the device with other components.

[0023] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Through the setting of the flexible hose, hydrochloric acid can directly enter the bottom of the storage tank, reducing the splashing of hydrochloric acid during the flowing process, preventing the disturbance of gas from accelerating the volatilization of hydrochloric acid. By setting the cylindrical flexible airbag, it can prevent excessive contact between the surface of hydrochloric acid in the storage tank and gas, reducing the problem of excessive volatilization of hydrochloric acid due to excessive contact with gas.

[0025] 2. Based on the flexible principle of the flexible tube, in different states of liquid inlet and liquid outlet, the flexible tube is in a flat shape or a straight tube shape, which not only ensures the liquid inlet speed during liquid inlet, but also prevents excessive contact between gas and the liquid in the storage tank through the flexible tube when the liquid inlet stops.

[0026] 3. By setting the liquid inlet component and the liquid outlet component, the balance between the liquid inlet volume and the gas outlet volume, as well as the liquid outlet volume and the gas inlet volume, can be ensured, thus completing the storage or discharge of hydrochloric acid.

Detailed Embodiment

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will combine the Figures 1 - 10 to clearly and completely describe the technical solutions of the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of this application fall within the scope of protection of this application.

[0039] Referring to Figure 1 、 Figure 2 、 Figure 7 and Figure 8 , this embodiment provides a hydrochloric acid storage tank, including a storage tank 1, a volatilization reduction component 2, a disassembly component 3, and an exhaust component 4. The volatilization reduction component 2 and the exhaust component 4 are both arranged inside the storage tank 1. The volatilization reduction component 2 is mainly used to reduce the volatilization amount of hydrochloric acid. The exhaust component 4 is used to control the entry and exit of gas inside the storage tank 1 to ensure that the amount of gas entering and exiting is balanced with the amount of hydrochloric acid entering and exiting. A disassembly component 3 is arranged on the storage tank 1, and the disassembly component 3 facilitates the connection of the storage tank 1 with other components.

[0040] Referring to Figure 1 、 Figure 3 and Figure 4 , the storage tank 1 is composed of an upper storage tank 11 and a lower storage tank 12. An inlet ring 13 is arranged on the upper storage tank 11, and an outlet ring 14 is arranged on the lower storage tank 12. The upper storage tank 11 and the lower storage tank 12 are arranged as cylindrical shapes of the same size. The opening of the upper storage tank 11 faces downward, and the opening of the lower storage tank 12 faces upward for assembly. The top of the upper storage tank 11 is provided with an inlet ring 13, and the bottom of the lower storage tank 12 is provided with an outlet ring 14. The upper storage tank 11, the lower storage tank 12, the inlet ring 13, and the outlet ring 14 are coaxially arranged.

[0041] Referring to Figure 2 、 Figure 5 and Figure 7, the volatilization reduction component 2 includes a cylindrical airbag 21, an airbag infusion tube 22, an airbag liquid outlet 23, and a pleated opening 24. The edge of the cylindrical airbag 21 is folded at the connection between the upper storage tank 11 and the lower storage tank 12. The cylindrical airbag 21 and the lower storage tank 12 are coaxially arranged and attached to the inner wall of the lower storage tank 12. The cylindrical airbag 21 is used to prevent excessive shaking of the hydrochloric acid entering the interior of the lower storage tank 12, reducing the contact between the hydrochloric acid and the gas. An airbag infusion tube 22 for transporting hydrochloric acid from the feed ring opening 13 to the bottom of the lower storage tank 12 is connected to the cylindrical airbag 21. The airbag infusion tube 22 and the cylindrical airbag 21 are coaxially arranged. An airbag liquid outlet 23 is connected between the airbag infusion tube 22 and the cylindrical airbag 21. A pleated opening 24 is provided in the middle of the airbag infusion tube 22. The pleated opening 24 allows the airbag infusion tube 22 to be folded along the pleated opening 24, so that the lower half of the airbag infusion tube 22 is sleeved on the airbag infusion tube 22 located in the upper half.

[0042] Refer to Figure 4 and Figure 6 , the volatilization reduction component 2 further includes an airbag liquid inlet 25 and a flexible liquid outlet valve 26. The airbag liquid inlet 25 is connected to the top of the airbag infusion tube 22 and is located at the feed ring opening 13. The flexible liquid outlet valve 26 is installed at the discharge ring opening 14 and is used to assist the hydrochloric acid to flow out of the lower storage tank 12.

[0043] During use, first, hydrochloric acid enters from the feed ring opening 13. The hydrochloric acid enters from the airbag liquid inlet 25 and directly reaches the bottom of the lower storage tank 12 along the airbag infusion tube 22. The cylindrical airbag 21 limits the hydrochloric acid to prevent it from splashing. As the liquid level of the hydrochloric acid rises, the cylindrical airbag 21 will move upward. Synchronously, the lower part of the airbag infusion tube 22 will fold upward along the pleated opening 24, so that the lower half of the airbag infusion tube 22 is sleeved on the airbag infusion tube 22 located in the upper half. When the bottom of the cylindrical airbag 21 is level with the pleated opening 24 in the middle, the cylindrical airbag 21 will fold onto the upper storage tank 11 and coincide with the inner wall of the upper storage tank 11 until the upper storage tank 11 and the lower storage tank 12 are filled up.

[0044] Refer to Figure 7 , the disassembly component 3 includes a semi-circular clamping plate ring 31, a flange 32, a compression ring 33, and a connecting thread 34. The semi-circular clamping plate ring 31 is set as two semi-circular rings of the same size. The semi-circular clamping plate ring 31 is sleeved on the outer wall of the feed ring opening 13. A flange 32 is threadedly connected to the top of the semi-circular clamping plate ring 31. A hole is provided in the flange 32. A compression ring 33 for fixing the airbag liquid inlet 25 is installed on the feed ring opening 13. A clamping opening is provided on the plane of the compression ring 33. The clamping opening is clamped on the feed ring opening 13. The outer wall of the compression ring 33 abuts against the inner wall of the flange 32.

[0045] In use, the compression ring 33 is snap-connected to the feed ring opening 13, so that the compression ring 33 presses the edge of the airbag liquid inlet 25. The two semi-circular clamping plate rings 31 surround the outer wall of the feed ring opening 13 and are threadedly connected using the flange 32. The flange 32 fixes the semi-circular clamping plate rings 31 and the compression ring 33. The holes on the flange 32 can be connected to other external parts through connecting parts. The connecting threads 34 provided on the compression ring 33 can be connected to other external components through threaded connection. At the same time, the compression ring 33 presses the airbag liquid inlet 25. The airbag liquid inlet 25, the airbag infusion tube 22, and the cylindrical airbag 21 can be disassembled and replaced by disassembling the semi-circular clamping plate rings 31, the flange 32, the compression ring 33, the upper storage tank 11, and the lower storage tank 12.

[0046] Referring to Figure 7 , Figure 8 and Figure 9 , the exhaust assembly 4 includes an exhaust hollow column 41, a rotating shaft 42, an exhaust valve 43, an exhaust hole 44, an air inlet hole 45, and an air inlet valve 46. The exhaust hollow column 41 is fixedly installed on the semi-circular clamping plate ring 31. There are two sets of the exhaust hollow columns 41 on each semi-circular clamping plate ring 31, and the two exhaust hollow columns 41 are symmetrically arranged. A rotating shaft 42 coaxial with the exhaust hollow column 41 is installed on the two semi-circular clamping plate rings 31. The exhaust hollow column 41 penetrates the inner and outer side walls of the clamping plate 53 and penetrates through the feed ring opening 13. Exhaust holes 44 are provided on three of the exhaust hollow columns 41, and three exhaust valves 43 acting on the exhaust holes 44 are installed on the two rotating shafts 42. An air inlet hole 45 is provided on the remaining one exhaust hollow column 41 and an air inlet valve 46 is installed. A hole corresponding to the air inlet hole 45 is provided on the rotating shaft 42.

[0047] Referring to Figure 9 , the clamping assembly 5 includes a connecting plate 51, a return spring 52, and a clamping plate 53. The clamping plate 53 is fixedly installed on the rotating shaft 42. The two clamping plates 53 are used to clamp the airbag infusion tube 22. The connecting plate 51 is fixedly installed on the rotating shaft 42. The connecting plate 51 and the clamping plate 53 are symmetrically installed. A return spring 52 is fixedly installed between the connecting plate 51 and the feed ring opening 13.

[0048] During use, the airbag infusion tube 22 is in a flat shape under the elastic force of the reset spring 52 and the clamping of the splint 53. When hydrochloric acid enters the lower storage tank 12 and the upper storage tank 11, the hydrochloric acid continuously passes through the airbag infusion tube 22, and the airbag infusion tube 22 is expanded, driving the rotation of the rotating shaft 42, so that the exhaust valve 43 on the rotating shaft 42 corresponds to the exhaust hole 44 on the exhaust hollow column 41, and the exhaust valve 43 discharges the gas inside the upper storage tank 11 from the exhaust hole 44 and the exhaust hollow column 41 in sequence; when the hydrochloric acid inside the lower storage tank 12 is discharged from the discharge ring opening 14, the airbag infusion tube 22 is in a flat shape under the clamping of the splint 53, and the hole on the rotating shaft 42 corresponds to the exhaust hole 44 opened on the exhaust hollow column 41. At this time, the intake valve 46 is started to make the same amount of gas enter the upper storage tank 11. Under the action of air pressure, the cylindrical airbag 21 can reciprocate between the upper storage tank 11 and the lower storage tank 12, so that the plane of the cylindrical airbag 21 is always in contact with the surface of the hydrochloric acid, preventing excessive contact between the hydrochloric acid and the gas.

[0049] Refer to Figure 10 , a twist cap 6 is provided on the discharge ring opening 14, and a telescopic spring 61 and a piston 62 are installed on the twist cap 6. The two ends of the telescopic spring 61 are respectively fixedly connected to the twist cap 6 and the piston 62. When the twist cap 6 is closed, the piston 62 abuts against the inner wall of the discharge ring opening 14, which can further ensure the sealing performance at the discharge ring opening 14.

[0050] The implementation principle of the hydrochloric acid storage tank in the embodiment of the present application is as follows:

[0051] When using this device, first fix the cylindrical airbag 21 through the assembly of the upper storage tank 11 and the lower storage tank 12, and fix the airbag liquid inlet 25 through the assembly of the semi-circular splint ring 31, the flange 32, and the compression ring 33. At this time, the cylindrical airbag 21 is in contact with the inner wall of the lower storage tank 12, pour hydrochloric acid from the airbag liquid inlet 25, and the hydrochloric acid directly enters the bottom of the lower storage tank 12 along the airbag infusion tube 22. As the liquid level of the hydrochloric acid rises, the lower part of the airbag infusion tube 22 folds along the fold opening 24 towards the upper part of the airbag infusion tube 22, and the cylindrical airbag 21 gradually moves up and coincides with the inner wall of the upper storage tank 11 as the liquid level of the hydrochloric acid rises. At the same time, the exhaust valve 43 extracts the gas inside the upper storage tank 11; when the hydrochloric acid inside the lower storage tank 12 is discharged from the discharge ring opening 14, the exhaust valve 43 extracts the gas inside the upper storage tank 11 to ensure the balance of the gas inflow and outflow and the hydrochloric acid inflow and outflow.

[0052] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "linked" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0053] The above is the preferred implementation manner of this application. It should be pointed out that for those of ordinary skill in the art, without departing from the principle described in this application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of this application.
