Technical Field

[0001] The utility model relates to the field of chemical sample processing, in particular to an automatic acid adding device for chemical samples. Background Art

[0002] Geochemical samples refer to various geological and environmental samples collected in geochemical research, such as rocks, minerals, soils, sediments, water bodies, etc. These samples contain information on geochemical elements and their isotopes. By analyzing these samples, the composition, structure, evolutionary history of the earth's materials and the geochemical cycle process, etc. can be understood, which is of great significance for studying the internal structure of the earth, geological processes, environmental evolution, etc.

[0003] In geochemical sample analysis laboratories, reagents such as volatile strong acids and alkalis are often used to dissolve samples. Most dissolution processes need to be heated on a hot plate, which accelerates the volatilization of reagents such as strong acids and alkalis. Experimental personnel need to dissolve hundreds of samples every day. During the process of adding acid one by one with an acid adding spoon, a large amount of repetitive labor easily leads to physical fatigue, and it is easy to inhale a large amount of volatilized reagents during the reagent adding process, causing harm to the body. In addition, the workload of quantitative acid adding one by one is cumbersome and huge, and it is also easy to cause uneven acid adding.

[0004] Therefore, an automatic acid adding device for chemical samples is now developed, which can achieve quantitative automatic acid adding to geochemical samples, reduce the labor intensity of experimental personnel, and protect the physical health of experimental personnel. Summary of the Utility Model

[0005] In order to overcome the shortcomings that a large amount of repetitive labor in the existing acid adding to geochemical samples easily leads to physical fatigue, and it is easy to inhale a large amount of volatilized reagents during the acid adding process, causing harm to the body, the utility model provides an automatic acid adding device for chemical samples, which can achieve quantitative automatic acid adding to geochemical samples, reduce the labor intensity of experimental personnel, and protect the physical health of experimental personnel.

The solenoid valve bracket is placed on the left side of the liquid adding pump. A controllable flow type solenoid valve is connected to the solenoid valve bracket. A liquid adding pipe is liquid-connected between the controllable flow type solenoid valve and the liquid adding pump.

[0007] Furthermore, both the reagent barrel and the liquid adding pipe are made of materials with strong acid resistance.

[0008] Furthermore, it also includes a longitudinal sliding rail, a liquid filling gun, a transverse sliding rail, an installation bracket, a vertical sliding rail, an installation base and a five-piece pipe.

The upper sides of the front and rear parts of the installation base are connected to the vertical sliding rails, and the installation bracket is slidably connected between the vertical sliding rails. The left and right parts of the installation bracket are connected to the longitudinal sliding rails, and a plurality of transverse sliding rails are connected between the longitudinal sliding rails.

[0010] Furthermore, it also includes a beaker, a hydraulic cylinder and an electric heating plate. The upper middle part of the device base is connected to two front and rear hydraulic cylinders, and an electric heating plate is connected between the telescopic ends of the hydraulic cylinders.

[0011] Furthermore, it also includes a heat preservation wire and a constant temperature wire. The heat preservation wire is connected inside the reagent barrel, and the constant temperature wire is connected to the controllable flow type solenoid valve.

Detailed implementation mode

[0018] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0019] An automatic acid adding device for chemical samples, as Figures 1-3 shown, includes a reagent barrel 1, a liquid adding pipe 2, a controllable flow type solenoid valve 11, a solenoid valve bracket 12 and a liquid adding pump 13.

The reagent barrel 1 and the liquid adding pipe 2 are both made of materials with strong acid resistance to avoid corrosion.

[0020] As Figure 1 and Figure 4 shown, it further includes a longitudinal sliding rail 3, a liquid adding gun 4, a transverse sliding rail 5, a device bracket 6, a vertical sliding rail 8, a device base 9 and a five-way tube 20. There are two device bases 9 on the left and right. The device bases 9 are both located on the left side of the solenoid valve bracket 12. Nine fixing screw holes 10 are opened on the device bases 9. The front and rear upper sides of the device bases 9 are both connected with vertical sliding rails 8. The device bracket 6 is slidably connected between the vertical sliding rails 8. The left and right parts of the device bracket 6 are both connected with longitudinal sliding rails 3. Five transverse sliding rails 5 are connected between the longitudinal sliding rails 3. The liquid adding guns 4 are slidably connected to the transverse sliding rails 5. The liquid adding guns 4 are all connected to the controllable flow type solenoid valve 11 through the five-way tube 20.

[0021] As Figures 1-4 shown, it further includes a wire arranging wheel 60, a beaker 7, a hydraulic cylinder 70 and a hot plate 71, a heat preservation wire 99 and a constant temperature wire 110.

[0022] When using the present utility model, first place the reagent barrel 1 in the chemical sample acid addition area, install the device base 9 on the left side of the reagent barrel 1 through bolts and fixed screw holes 10, then connect the reagent barrel 1 to the liquid addition pump 13 through the liquid addition pipe 2, connect the liquid addition pump 13 to the controllable flow type solenoid valve 11 through the liquid addition pipe 2, then connect the controllable flow type solenoid valve 11 to the liquid addition gun 4 through the five-way pipe 20, then start the hydraulic cylinder 70 to make the electric heating plate 71 move downward, and then place 10*5 beakers 7 containing chemical samples on the electric heating plate 71 respectively. Due to the variety of geochemical samples, the sizes and spacings of the beakers 7 may not be consistent.

When it is necessary to add acid to the chemical samples, start the horizontal sliding rail 5, the vertical sliding rail 3 and the vertical sliding rail 8, adjust the position of the liquid addition gun 4 above the leftmost beaker 7, then start the liquid addition pump 13, then open the controllable flow type solenoid valve 11 and adjust the liquid addition amount, so that the reagent in the reagent barrel 1 flows through the controllable flow type solenoid valve 11 through the liquid addition pipe 2 and then flows from the five-way pipe 20 to the liquid addition gun 4, so that the liquid addition gun 4 can complete the liquid addition of five beakers 7 at the same time, and then repeat the work from left to right in turn to complete the acid addition of all chemical samples, so as to realize the quantitative automatic acid addition to geochemical samples, reduce the labor intensity of experimental personnel and protect the physical health of experimental personnel. When adding acid to the chemical, start the heat preservation wire 99 and the constant temperature wire 110 to keep the reagent in the reagent barrel 1 and the five-way pipe 20 warm. When connecting the controllable flow type solenoid valve 11 to the liquid addition gun 4 through the five-way pipe 20, make the five-way pipe 20 pass through between the wire arranging wheels 60 to prevent the five-way pipe 20 from knotting during the movement of the liquid addition gun 4.
