It needs to be extracted and then the internal substances are separated by steam.

[0003] In chemical experiments, biological separation and extraction is carried out through precipitation, adsorption, extraction, and ultrafiltration. Some impurities need to be removed during pretreatment, such as foreign proteins, polysaccharides, inorganic ions, etc., and then heated to reduce viscosity, remove foreign proteins, and increase particle size through coagulation and flocculation. Then, the mixture is filtered through a vacuum filter and a plate and frame filter. Some are filtered through steam. Different amounts of heating are required for testing during the extraction process, but high temperature will produce steam. If the cover is opened manually, it will cause burns.

Because existing chemical experiments require the use of measuring cups to add reagents inside biological separation and extraction equipment, and some extraction equipment extracts through steam distillation, in order to view different experimental extraction results, the existing cover needs to be opened manually, which makes it easy to be scalded by steam; 2. Because existing chemical experiments consider that steam is easy to burn or it is inconvenient to add too high a level, pipeline addition is used, which makes it impossible to check the added amount, affecting the collection of different data, causing inconvenience in extraction in the biological separation and extraction equipment, thereby affecting the accuracy of the added data.

[0023] In this embodiment, Figure 1 , Figure 2 and Figure 4As shown, the slide 4 includes a first movable plate 401, a second movable plate 408 is attached to one side of the first movable plate 401, the upper part of the first movable plate 401 is respectively plugged into the auxiliary folding plate 402 and the first opening and closing folding plate 410 through a latch, the upper part of the second movable plate 408 is respectively plugged into the second opening and closing folding plate 409 and the control folding plate 407 through a latch, the upper part of the first opening and closing folding plate 410 is plugged into the first incomplete gear 403 through a latch, one side of the first incomplete gear 403 is meshedly connected with the second incomplete gear 411, the lower part of the control folding plate 407 passes through the first gear 406, one side of the first gear 406 is meshedly connected with the second gear 405, the upper part of the second gear 405 is plugged with the first motor 404, and the second gear 405 is meshedly connected with the second gear 405 through the The first motor 404 forms a rotating structure, and the first gear 406 forms a rotating structure through the second gear 405; because chemical experiments generally require repeated addition of reagents to detect the amount of different reagents added, in biological separation and extraction equipment, the cover is generally on the top, and chemical experiment extraction generally uses high and low temperatures for extraction and separation. The existing cover is on the top, and the general equipment is fixed by a support frame. When it is opened, it is easy to be scalded by the internal steam. The improvement is now provided with a first motor 404 to drive the second gear 405 below to rotate, and the second gear 405 drives the first gear 406 to rotate, so that the first gear 406 drives the control folding plate 407 to rotate, thereby achieving the driving effect, so that the cover can be automatically opened, thereby achieving the effect of the first gear 406 driving the control folding plate 407 to drive.

[0024] In this embodiment, Figure 1 , Figure 2 and Figure 4 The second opening and closing folding plate 409 is shown to form a reciprocating structure through the first incomplete gear 403 and the second incomplete gear 411, and the first movable plate 401 and the second movable plate 408 form a sliding structure through the slide groove 4; because the existing chemical experiments need to be checked repeatedly to check the experimental results, the existing cover is repeatedly opened, which is easy to be scalded by steam, and cannot be closed quickly.
