Description

Technical Field

[0001] This utility model relates to the field of sulfuric acid filling machines, and in particular to a sulfuric acid filling mechanism with good protective effect. Background Technology

[0002] Concentrated sulfuric acid has a boiling point of over 300 degrees Celsius and a low vapor pressure at room temperature, but it still exhibits slight volatility. Especially during the filling process, when sulfuric acid is injected into the storage tank from the pipeline, it impacts and disturbs the liquid surface, forming fine droplets and sprays. These droplets greatly increase the contact area between the sulfuric acid and the air, thereby accelerating the release of volatile gases.

[0003] Sulfuric acid mist generated during the sulfuric acid filling process can severely irritate the respiratory tract, causing coughing and burns. Long-term or high-concentration exposure can lead to bronchitis, pneumonia, and even pulmonary edema. It is also highly corrosive to the eyes and skin. If no corresponding protective measures are taken during sulfuric acid filling, the health risks to workers in the environment are high. Therefore, a sulfuric acid filling facility with good protective effect is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a sulfuric acid filling mechanism with good protective effect, which can absorb and treat sulfuric acid mist during the sulfuric acid filling process.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a sulfuric acid filling mechanism with good protective effect, including a base plate, a support plate fixedly installed on the top of the base plate, a tray fixedly installed on the right side of the support plate, a conveying pipe on the top of the tray, a filling pipe connected to the other end of the conveying pipe, a cover fitted over the filling pipe, a drive push rod fixedly installed on the right side of the tray, a support rod fixedly installed at the output end of the drive push rod, and a limiting ring with one end fixedly connected to the support rod fitted over the filling pipe.

[0007] An air pump is fixedly installed on the left side of the support plate. The air pump's air inlet is connected to an air suction pipe, and the other end of the air suction pipe is connected to an air extraction pipe that extends through to the bottom of the cover.

[0008] The base plate is equipped with a purification component, and the sulfuric acid volatile gas drawn by the air pump is sent into the purification component for purification.

[0009] As a preferred embodiment of this utility model, the delivery pipe is a flexible hose, and its other end is connected to a chemical pump.

[0010] As a preferred embodiment of this utility model, the cover is a stainless steel cover and the exhaust pipe is an extension hose.

[0011] As a preferred embodiment of this utility model, the purification component includes a purification chamber fixed to the top of the base plate, which stores an alkaline liquid for neutralizing and purifying sulfuric acid volatile gases.

[0012] As a preferred embodiment of this utility model, the air outlet of the air pump is connected to an air supply pipe, the other end of the air supply pipe is connected to an exhaust pipe that penetrates into the purification chamber, and the bottom of the exhaust pipe is connected to a plurality of air outlets.

[0013] As a preferred embodiment of this utility model, the exhaust pipe is a stainless steel pipe, and the part of the exhaust pipe located outside the purification chamber is equipped with a one-way valve, which is used to prevent the liquid inside the purification chamber from flowing back.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention incorporates a cover, an air pump, an air intake pipe, an air extraction pipe, and a purification component. During sulfuric acid filling, the air pump delivers the emitted sulfuric acid mist into the purification component via the air intake and air extraction pipes. This prevents a large amount of sulfuric acid mist from spreading into the filling workshop. The sulfuric acid mist is absorbed by alkaline solutions such as sodium hydroxide solution, protecting the health of the workers in the workshop. Attached Figure Description

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] In the attached diagram, all identical reference numerals refer to the same components.

[0022] Example 1

[0023] like Figure 1-2 As shown, this utility model provides a sulfuric acid filling mechanism with good protective effect, including a base plate 1. A support plate 2 is fixedly installed on the top of the base plate 1 to support the entire filling mechanism. A support plate 3 is fixedly connected to the right side of the support plate 2 to support and guide the delivery pipeline. A delivery pipe 4 is provided on the top of the support plate 3. The delivery pipe 4 is preferably a corrosion-resistant hose. Its left end is connected to the outlet of a chemical pump (not shown in the figure). The chemical pump is used to pump concentrated sulfuric acid out of the storage tank. The right end of the delivery pipe 4 is connected to a filling pipe 5, through which sulfuric acid is filled into the target container.

[0024] In addition, a cover 6 is provided on the outside of the injection tube 5. The cover 6 is preferably made of stainless steel, which has good corrosion resistance and structural strength. Its shape is designed to cover the outlet of the injection tube 5 and the mouth of the container, forming a relatively closed space to limit the escape of sulfuric acid mist.

[0025] Furthermore, to accommodate containers of different heights, a drive push rod 7 is fixedly installed on the right side of the pallet 3. This drive push rod 7 can be an electric push rod or a pneumatic push rod. A support rod 8 is fixedly connected to the output end of the drive push rod 7. A limiting ring 9 is also fitted around the outside of the filling tube 5, and one end of the limiting ring 9 is fixedly connected to the support rod 8. By controlling the extension and retraction of the drive push rod 7, the support rod 8 and the limiting ring 9 can be moved up and down, thereby adjusting the height of the filling tube 5 and the sealing cover 6 to ensure that the sealing cover 6 can effectively cover the container opening.

[0026] In this embodiment, an air pump 10 is fixedly installed on the left side of the support plate 2. The air inlet of the air pump 10 is connected to a suction pipe 11 via a pipeline, and the other end of the suction pipe 11 is connected to a suction pipe 12. The suction pipe 12 is preferably a corrosion-resistant extension hose, one end of which penetrates the cover 6 and extends to the area below it near the liquid surface impact zone. When the air pump 10 is working, it draws out the sulfuric acid mist generated inside the cover 6 through the suction pipe 11 and the suction pipe 12.

[0027] In this embodiment, a purification assembly is provided on the base plate for treating the sulfuric acid mist gas drawn by the air pump 10. In this embodiment, the purification assembly includes a purification chamber 13 fixedly installed on the top of the base plate 1. The purification chamber 13 stores an alkaline liquid for neutralizing the sulfuric acid mist, such as a sodium hydroxide solution or sodium carbonate solution with a mass fraction of 5%-10%.

[0028] In addition, the outlet of the air pump 10 is connected to an air supply pipe 14, and the other end of the air supply pipe 14 is connected to an exhaust pipe 15. The exhaust pipe 15 penetrates the wall of the purification chamber 13 and extends below the liquid level inside. The exhaust pipe 15 is preferably a stainless steel pipe. In the lower section of the exhaust pipe 15 located inside the purification chamber 13, multiple air outlets 16 are connected to its bottom to disperse the sulfuric acid mist-containing gas into fine bubbles for discharge, thereby increasing the gas-liquid contact area and improving the neutralization reaction efficiency. To prevent the alkaline liquid in the purification chamber 13 from backflowing due to siphon or other reasons when the air pump stops working, a one-way valve is installed on the section of the exhaust pipe 15 located outside the purification chamber 13.

[0029] In summary, during sulfuric acid filling operations, the chemical pump and air pump 10 are started. Sulfuric acid is poured into the container through the delivery pipe 4 and the filling pipe 5. Simultaneously, the drive rod 7 adjusts the position of the cover 6 according to the container height, effectively covering the filling area. Sulfuric acid mist generated during filling is confined within the space of the cover 6, and the air pump 10 continuously removes this mist through the extraction pipe 12. The gas containing sulfuric acid mist is sent into the alkaline liquid in the purification chamber 13 through the air supply pipe 14 and the exhaust pipe 15. The sulfuric acid mist undergoes a neutralization reaction with the alkaline solution, producing sodium sulfate or sulfate and water, thus achieving harmless treatment. The purified gas is discharged from the top of the purification chamber 13, greatly reducing the diffusion of toxic and harmful gases in the workshop and effectively protecting the health of operators.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
