DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] As mentioned in the background art, the digestion instrument in the prior art cannot quickly and evenly mix the sample and the acid solution in the digestion tube, resulting in low digestion efficiency. The utility model provides a water quality decomposition and digestion instrument.

[0024] Example 1

[0025] Reference Figures 1 to 3 A water quality decomposition and digestion instrument, comprising a box body 1 and a support leg 13 arranged at the bottom of the box body 1, a cross bar 2 and a cross frame 3 respectively penetrate the left and right sides of the box body 1, and the opposite sides of the cross bar 2 and the cross frame 3 are connected to the mesh plate 4, so that when the cross frame 3 drives the mesh plate 4 to move back and forth laterally, the cross bar 2 can move back and forth on the box body 1 for guidance;

[0026] The top of the mesh plate 4 is evenly provided with clamping components;

[0027] The clamping assembly is in contact with the digestion tube 6 and is used to clamp the digestion tube 6, so that the mesh plate 4 moves back and forth horizontally, driving the digestion tube 6 to move back and forth horizontally. The digestion tube 6 contains water samples and acid solutions.

[0028] The box body 1 is provided with a heating rod 8 below the mesh plate 4, which is used to generate heat during operation and heat the digestion tube 6;

[0029] A dual-axis motor 9 is provided at the bottom of the box body 1, and a fan blade 10 located in the box body 1 is provided on the top output shaft of the dual-axis motor 9, and the fan blade 10 is located below the heating rod 8, so that when the dual-axis motor 9 is working, the fan blade 10 rotates, and the heat generated by the heating rod 8 can be quickly blown onto the digestion tube 6 for heating;

[0030] An air inlet net 11 is provided at the bottom of the box body 1, and an exhaust net 12 is provided at the top of the outer wall of the box body 1 for the air to enter and exit;

[0031] A driving assembly is arranged on the bottom output shaft of the dual-axis motor 9 , and the driving assembly is connected to the cross frame 3 .

[0032] The bottom of the digestion tube 6 is provided with supporting feet 5, and the bottom of the supporting feet 5 is closely connected to the mesh plate 4. The supporting feet 5 are provided so that the bottom of the digestion tube 6 is suspended in the air and can be better heated by heat.

[0033] The driving assembly includes a driving gear 17 arranged on the output shaft at the bottom of the dual-axis motor 9, and a driven gear 18 is meshed and connected to the driving gear 17. The driven gear 18 is arranged on a rotating shaft 19, and the rotating shaft 19 is connected to a mounting rod 20 through a bearing. The mounting rod 20 is arranged on a support leg 13. A rotating plate 21 is arranged at the bottom of the rotating shaft 19, and a movable rod 22 is connected to the eccentric bottom of the rotating plate 21 through a pin shaft. The movable rod 22 is connected to the cross frame 3 through the pin shaft. The driving gear 17 drives the driven gear 18 to rotate, so that the rotating shaft 19 drives the rotating plate 21 to rotate, and the movable rod 22 drives the cross frame 3 to move back and forth horizontally, thereby shaking the sample and the acid solution in the digestion tube 6, so as to quickly mix them evenly and improve the digestion efficiency.

[0034] The radius of the driving gear 17 is smaller than that of the driven gear 18 , so that the rotation speed of the rotating shaft 19 is lower than that of the fan blades 10 , thereby reducing the frequency of shaking of the digestion tube 6 and improving practicality.

[0035] The clamping assembly includes two groups of mounting boxes 23 with the same structure. The bottoms of the mounting boxes 23 on both sides are arranged on the mesh plate 4. Electric telescopic rods are arranged inside the mounting boxes 23 on both sides, and connecting rods 24 that penetrate the mounting boxes 23 are arranged on the output ends of the electric telescopic rods. The electric telescopic rods are located inside the mounting boxes 23 to avoid being blown by hot air to reduce the service life. Arc-shaped porous clamps 25 are arranged on the connecting rods 24 on both sides. The front and rear sides of the digestion tube 6 are respectively in contact with the porous clamps 25 on both sides. The porous clamps 25 are driven by the connecting rods 24 to move to clamp and prevent the digestion tube 6 from loosening. Since the porous clamps 25 are porous structures, the coverage of the outer wall of the digestion tube 6 can be reduced to reduce the impact on the heating of the digestion tube 6.
