[0009] As a preferred technical solution of the present invention: both ends of the outer wall of the driving screw are provided with internal threads, and the threads at both ends of the outer wall of the driving screw are in opposite directions.

[0010] As an optimal technical solution of the present invention: there are two driving screws, and the two driving screws are respectively installed on both sides of the inner cavity of the fixed bin, and a rubber anti-slip pad is installed on the outer wall of the pressure plate close to the evaporator.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This food ash content determination pretreatment device uses a fixing box arranged on the outer wall of the support net and a driving spring arranged in the inner cavity of the fixing box.

[0023] In a preferred embodiment, two ends of the outer wall of the driving spring 7 are in contact with the outer wall of the telescopic plate 6 and the inner wall of the fixing box 5 respectively, and the driving spring 7 is made of high carbon steel.

[0024] By arranging the telescopic plate 6 and the driving spring 7 in the inner cavity of the fixing box 5, the telescopic plate 6 can be driven under the action of the driving spring 7, so that the outer wall of the telescopic plate 6 can be moved out of the inner cavity of the fixing box 5, so that the outer wall of the pressing plate 9 is attached to the inner wall of the evaporating pot 1, thereby achieving the purpose of fixing the support net 4.

[0025] In a preferred embodiment, a movable groove is formed in the inner cavity of the fixing box 5 , and the shape of the inner wall of the movable groove matches the shape of the outer wall of the telescopic plate 6 .

[0026] By means of the movable groove opened in the inner cavity of the fixed box 5, and the telescopic plate 6 and the driving spring 7 provided in the inner cavity of the fixed box 5, the outer walls of the telescopic plate 6 and the pressure plate 9 can be fitted to the inner wall of the evaporation pot 1 under the action of the driving spring 7. When the position of the support net 4 needs to be adjusted, it is only necessary to pull the push rod 8, and the outer wall of the pressure plate 9 can be separated from the inner wall of the evaporation pot 1 under the action of the push rod 8, thereby realizing the adjustment of the position of the support net 4.

[0027] In a preferred embodiment, an inner wall of the clamping plate 12 at one end away from the limiting rod 11 is provided with an internal thread, and the inner wall thread of the clamping plate 12 is meshed with the outer wall thread of the driving screw 13 .

[0028] By setting a clamping plate 12 on the outer wall of the limiting rod 11, and the inner wall of the clamping plate 12 and the outer wall of the driving screw 13 are engaged with each other, when the knob 14 is turned, the driving screw 13 can be driven to rotate under the action of the knob 14, and the clamping plate 12 can be driven under the action of the driving screw 13, so that the clamping plate 12 moves back and forth along the outer wall of the driving screw 13.

[0029] In a preferred embodiment, both ends of the outer wall of the driving screw rod 13 are provided with internal threads, and the threads at both ends of the outer wall of the driving screw rod 13 are in opposite directions.

[0030] By providing external threads at both ends of the outer wall of the driving screw 13, and with the threads at both ends in opposite directions, when the driving screw 13 is rotated, the clamping plates 12 on both sides can be driven to move relative to each other, and move inward or outward at the same time, thereby achieving the fixation of the evaporation container under the action of the clamping plates 12.

[0031] In a preferred embodiment, there are two driving screws 13 , which are respectively installed on both sides of the inner cavity of the fixed bin 10 , and a rubber anti-slip pad is installed on the outer wall of the pressing plate 9 close to the evaporator 1 .

[0032] By setting the driving screws 13 on both sides of the inner cavity of the fixed bin 10, the four clamping plates 12 can be driven by the action of the two driving screws 13, so that the two evaporation containers can be fixed under the action of the clamping plates 12, so that beverages such as juice and milk can be evaporated under the action of the evaporation containers.

[0033] Working principle: During the use of the above-mentioned device, when it is necessary to ash liquid samples such as juice and milk, the sample needs to be pre-treated. An appropriate amount of sample is accurately weighed and placed in an evaporation container of known mass. It is placed on a water bath and evaporated until almost dry, and then carbonized. Only then can accurate ashing data be better obtained. At this time, the position of the support net 4 is adjusted according to the length of the evaporation container. By pulling the push rod 8, the telescopic plate 6 is retracted into the inner cavity of the fixing box 5, and the driving spring 7 is compressed. At this time, the outer wall of the pressure plate 9 can be separated from the inner wall of the evaporation pot 1, thereby unlocking the support net 4, and thus the support position of the support net 4 can be adjusted. After the adjustment is completed, the bottom of the evaporation container can contact the top of the support net 4. Then, the knob 14 is turned. Under the action of the knob 14, the drive screw 13 is driven to rotate, thereby causing the clamping plates 12 on both sides to move inward at the same time. Under the action of the clamping plates 12 on both sides, the evaporation container is clamped and fixed, ensuring that it is stably placed in the inner cavity of the evaporation pot 1, and better water evaporation work.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
