Description

Technical Field

[0001] The utility model relates to the field of acid expulsion, and specifically relates to a waste absorption device during acid expulsion in a laboratory. Background Technique

[0002] Acid expulsion is a process of heating a large amount of sample dissolution acid or adding sulfuric acid, perchloric acid, etc. and heating to drive it away. This is usually to reduce the acidity of the solution for subsequent analysis and determination.

[0003] In the current waste absorption device during acid expulsion in a laboratory, waste gas is generally collected and then neutralized. However, when absorbing and neutralizing waste gas, it is generally inconvenient to control and adjust the quantity of the transmission pipeline, resulting in excessive transmission of waste gas, insufficient neutralization reaction, and too little transmission of waste gas, which leads to poor neutralization reaction efficiency and affects the subsequent work efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a waste absorption device during acid expulsion in a laboratory to achieve the purpose of solving the above problems in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A waste absorption device during acid expulsion in a laboratory, including a base; a storage cylinder fixedly connected to the top of the base; a reaction cylinder fixedly connected to the top of the base; an adjustment part arranged on the outer wall of the storage cylinder; a fixing part arranged on one side of the adjustment part.

[0006] Preferably, the adjustment part includes: an air extraction pump communicated and arranged on the outer wall of the storage cylinder; a transmission pipe communicated and arranged on the outer wall of the reaction cylinder.

[0007] Preferably, a fixing frame is arranged between the air extraction pump and the transmission pipe.

One end of the sliding rod is fixedly connected with a baffle plate, and the baffle plates are arranged at equal circumferential intervals. The baffle plates are slidably connected between the inner walls of the fixing frame. The baffle plates are adapted to the air extraction pump and the transmission pipe. The other end of the sliding rod is fixedly connected with a slider, and a limiting post is fixedly connected to one side of the slider, and the limiting posts are symmetrically arranged.

[0009] Preferably, one side of the fixed frame is rotatably connected to a linkage rod through a shaft rod. The linkage rods are arranged equidistantly in a circle. One end of the linkage rod is rotatably connected to a sliding rail through a shaft rod. The sliding rails are arranged equidistantly in a circle. The sliding rail is adapted to the slider. A sliding opening is formed on the outer wall of the sliding rail, and the sliding opening is adapted to the limiting column.

[0010] Preferably, the fixing part includes: a fixed seat fixedly connected to one side of the sliding rail; a limiting groove block fixedly connected to one side of the fixed frame, and the fixed frames are arranged at equal intervals.

[0011] Preferably, one side of the fixed seat is rotatably connected to a clamping rod through a shaft rod. The clamping rod is adapted to the limiting groove block.

[0013] The utility model provides a waste absorption device during laboratory acid expulsion. It has the following beneficial effects:

[0014] (1) By pressing the sliding rail, the sliding rail slides downward. Thus, under the action of the linkage rod, the other sliding rails are controlled to slide simultaneously, so that the sliding rail slides obliquely downward. Under the action of the limiting column and the slider, the sliding rod is controlled to slide along the track of the guiding rail, thereby driving the baffle to slide, so as to control the gap between the baffles and achieve the purpose of adjusting the exhaust speed of the air extraction pump.

[0015] (2) After adjusting the sliding rail to a suitable position, rotate the clamping rod to squeeze the clamping block. When the clamping rod is completely inserted into the inside of the limiting groove block, under the action of the spring, the clamping block rebounds to clamp and fix the clamping rod, achieving the purpose of fixing the position of the sliding rail. When the exhaust rate needs to be adjusted, press the braking rod to squeeze the clamping block, so that the clamping block is no longer clamped and connected to the clamping rod, and the clamping rod is rotated out to achieve the effect of quickly adjusting and fixing the position of the sliding rail.
