Description

Technical Field

[0001] The utility model relates to the technical field of fine chemicals, in particular to a temporary storage and turnover barrel for acidic solutions. Background Art

[0002] A temporary storage and turnover barrel for acidic solutions refers to a container used for temporarily storing acidic solutions. Acidic solutions are divided into strong acids and weak acids. Among them, acidic solutions are often used in chemical experiments in laboratories. For the convenience of operation, a certain amount of acidic solution is generally stored in the temporary storage and turnover barrel first. When conducting experiments, a part of the acidic solution in the temporary storage and turnover barrel is poured out for the experiment. Therefore, the temporary storage and turnover barrel is essential for storing acidic solutions.

[0003] At present, the existing temporary storage and turnover barrels for acidic solutions use containers with threaded caps for storage. When taking out the acidic solution, the threaded cap is directly opened to pour out the acidic solution. To facilitate the addition of acidic solution into the temporary storage and turnover barrel, a relatively large discharge port is generally set. When pouring out the acidic solution, if the inclination angle of the turnover barrel is not well controlled, the outflow rate of the acidic solution is relatively fast, which may cause splashing, resulting in waste of acid solution. At the same time, the splashed acid solution has certain potential safety hazards. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a temporary storage and turnover barrel for acidic solutions that can overcome or at least partially solve the above problems.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A temporary storage and turnover barrel for acidic solutions includes: a turnover barrel body, and further includes: a handle provided on the turnover barrel body; a feed port provided on one side of the turnover barrel body; a discharge port provided on the side of the turnover barrel body away from the feed port; a first sealing cap threadedly connected to the discharge port; a second sealing cap threadedly connected to the feed port; a stop block fixedly provided inside the turnover barrel body, and a flow-limiting groove is provided between the stop block and the turnover barrel body, and the flow-limiting groove matches the discharge port.

[0007] To facilitate ventilation and flow blocking, further, a through hole is provided on the stop block, and a flow-blocking plate matching the through hole is fixedly connected to the discharge port.

[0008] To facilitate the complete discharge of the acidic solution inside the turnover barrel body, further, an inclined surface is provided on the side of the stop block away from the flow-limiting groove.

[0009] To prevent the convective flow of overflow gas to the hand, further, a cavity is provided inside the second sealing cover. A connecting pipe is provided between the cavity and the threaded side of the second sealing cover. A round hole is provided on the second sealing cover, and a sealing rod is threadedly connected inside the round hole.

[0010] To facilitate the neutralization reaction of acid mist in the gas, preferably, a mesh plate is provided inside the cavity, and a sponge is fixedly connected to the mesh plate.

[0011] To prevent the gas from overflowing from the lower side of the second sealing cover, further, a retaining ring is fixedly connected to the turnover barrel body, and the retaining ring is in sealed sliding connection with the second sealing cover.

[0012] Compared with the prior art, the present utility model provides a temporary storage turnover barrel for acidic solutions, having the following beneficial effects:

[0013] 1. For this temporary storage turnover barrel for acidic solutions, when filling the acidic solution into the turnover barrel body, open the second sealing cover, add the acidic solution into the turnover barrel body. When a small amount of acidic solution needs to be taken out during laboratory experiments, prepare a container for holding the acidic solution, then open the first sealing cover, pour out the acidic solution in the turnover barrel body. At this time, the flow rate of the acidic solution is limited by the flow limiting groove, thereby effectively preventing the acidic solution from splashing due to too fast a flow rate, and at the same time, the accuracy of the poured volume of the acidic solution can be effectively controlled.

[0014] 2. For this temporary storage turnover barrel for acidic solutions, first remove the sealing rod, then rotate the second sealing cover one turn to connect the pipe orifice on the inner side of the second sealing cover with the turnover barrel body. At this time, if there is acid mist and a certain air pressure in the turnover barrel body, the gas enters the cavity through the connecting pipe. The alkaline solution on the sponge in the cavity reacts with the acid for neutralization. At this time, the reacted gas is discharged through the round hole, thereby effectively preventing acid mist gas from directly spraying out and contacting the skin of the staff when the first sealing cover is opened, and effectively purifying the acid mist gas.

[0015] Parts not involved in this device are the same as or can be implemented using the prior art. The present utility model effectively prevents the acidic solution from splashing due to too fast a flow rate, can effectively control the accuracy of the poured volume of the acidic solution, and effectively prevents acid mist gas from directly spraying out and contacting the skin of the staff when the first sealing cover is opened, and further effectively purifies the acid mist gas.
