Description

A special soaking device for laboratory acid tank

technical field

The utility model belongs to the technical field of detection, in particular to a special soaking device for laboratory acid vats.

Background technique

Acid jars are often used to soak glassware used in experiments, which can achieve the purpose of cleaning and disinfecting experimental vessels, and are necessary equipment for laboratories. However, the structure of the current acid tank is relatively simple, with only one large cavity. After the experimental utensils are put in, they can only be placed at the bottom of the acid tank. Due to the limited capacity of the acid tank, irregular-shaped When using different glassware, it is easy to cause the experimental vessel to be broken due to mutual extrusion and collision, which is inconvenient to use and has potential safety hazards, and the volume of the inner cylinder of the acid tank cannot be fully utilized. Secondly, before microbiological experiments and trace substance analysis and detection, acid jars are often used to soak small-volume glassware and a large number of glass straws to eliminate residues on the inner wall of glassware. Because glassware is affected by factors such as its shape and buoyancy, The glassware placed in the acid tank often floats in the acid solution, indicating that it is difficult to fill each glass vessel with acid solution to meet the immersion requirements. It is often necessary for the operator to wear rubber gloves to press the glassware into the lower layer of the acid solution one by one, so that each vessel is filled with the acid solution to achieve the purpose of sinking the acid solution. However, there is a great danger in this operation process. When the container is pressed down, air bubbles will appear on the surface of the acid liquid, and the acid liquid will splash out. Especially when the container with small volume and small diameter is soaked, it is more dangerous for the operator. big. In the process of taking out the glassware, wear rubber gloves, open the lid of the acid tank, and slowly lift the inner tank from the outer tank, so that the acid in the inner tank can leak into the outer tank through the small holes on the walls and bottom of the inner tank. cylinder. Then, put out the inner barrel and pour the acid solution in the glass instrument into the outer barrel. This operation process is time-consuming and laborious, and there is also great danger.

Detailed ways

The technical scheme of the utility model is further described in detail below in conjunction with the accompanying drawings.

As shown in Fig. 1-4, the special soaking device for the laboratory acid vat is mainly composed of an open cylindrical soaking barrel 1 without a cover, a detachable gland 5 and an S-shaped hook 8. The inner diameter of the cylindrical soaking barrel 1 is set to 15-18cm, the outer diameter is set to 16-19cm, the thickness is set to 0.3-0.5cm, and the height is 35-40cm.

The side wall and the bottom of the cylindrical soaking barrel 1 are of mesh structure, two handles 4 are arranged on the upper end of the barrel body, and the bottom of the barrel body is a double-layer mesh structure, including the first barrel bottom 2 and the second barrel bottom 3. The distance between the bottom 2 of the first barrel and the bottom 3 of the second barrel is set to 1-2cm. The setting of the double-layer mesh bottom of the barrel can avoid the glass straw soaked in it (the straw mouth is placed downward) and other substances in the acid solution. Containers collide and break due to contact. The upper end of the cylindrical soaking barrel 1 is provided with two handles 4, which are convenient for experimenters to soak and take out small glassware and glass straws. The operation does not need to lift the entire inner vat to avoid direct contact with acid, which can reduce the risk of operation and labor. strength.

The detachable gland 5 is a plane and circular structure with a diameter smaller than the inner diameter of the barrel body 1, and can be placed horizontally in the open cylindrical barrel body 1. The center of the gland 5 is provided with a round hole 6, and the periphery of the round hole 6 is provided with Small hole 7, the configuration quantity of gland 2 can be 3-5, and described circular gland 5 diameters are 12-14cm, and thickness is 0.5-0.7cm, and the circular hole 6 diameter of gland 5 center is set as 2- 2.5cm, the diameter of the small hole 7 around is set to 0.8-1.0cm. The gland 5 placed on the glassware of the barrel body 1 can make the small glassware quickly fill with acid liquid and sink to achieve the purpose of acid bubbles. The round hole 6 and small hole 7 on the gland 5 can prevent the small glassware from floating up , Spray acid, improve operational safety and work efficiency.

The length L of the S-shaped hook 8 is set to 4-5cm, the width a is set to 1.8-2.3cm, the wire diameter Φ is set to 4-5mm, the S-shaped hook 8 is an accessory device, and the number of equipment is set to 10. One end of the S-shaped hook 8 is hung on the upper edge of the inner cylinder of the acid tank, and the other end is hung on the side wall of the mesh soaking barrel 1, so that the soaking barrel 1 can be hung horizontally on the upper edge of the inner cylinder, and glassware and Drain and return the remaining acid in the straw to the acid tank to avoid wasting acid.

As a further improvement of the utility model, the soaking barrel 1 and the S-shaped hook 8 are made of high-density plastic material (polytetrafluoroethylene) resistant to strong acid, corrosion and oxidation, and the material of the gland 5 can be ceramics or Teflon.
