Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

As shown in fig. 1-4, the microwave digestion instrument according to the preferred embodiment of the present invention includes a box body 1, a turntable 2, a mounting bracket 3, a digestion tank 4 and a driving unit, wherein the turntable 2 is provided with a heating cavity 11 in the box body 1, the turntable 2, the mounting bracket 3 and the digestion tank 4 are all disposed in the heating cavity 11, the mounting bracket 3 is removably disposed on the turntable 2, the digestion tank 4 is removably disposed on the mounting bracket 3, the digestion tank 4 includes a tank body 41 and a protection cover 42, wherein the tank body 41 includes a pressure sleeve 411, a sample tube 412 is contained in the pressure sleeve 411, the sample tube 412 is used for placing a sample, the pressure sleeve 411 is used for bearing the pressure generated in the process, and the digestion of the sample tube 412 is avoided. The protective cover 42 is detachably covered on the opening of the tank body 41, specifically, the outer wall of the tank body 41 is provided with an external thread, the protective cover 42 is provided with an internal thread, the tank body 41 is in threaded connection with the protective cover 42, and after a sample is loaded, the protective cover 42 is directly screwed on the tank body 41. The protective cover 42 is provided with a pressure relief device 6 communicated with the tank 41.

Appearance is cleared up to microwave based on above-mentioned technical characteristic, through set up the intercommunication on protective cover 42 the pressure relief device 6 of the jar body 41, when clearing up the pressure in jar 4 too big, clear up gaseous through pressure relief device 6 row heating chamber 11 that the process produced to effective control clears up the pressure in jar 4, has avoided clearing up jar 4 because the too big explosion that produces of pressure has improved factor of safety. The utility model discloses simple structure, excellent in use effect easily uses widely.

In addition, to clear up jar 4 and can remove the ground and set up on mounting bracket 3, install mounting bracket 3 on carousel 2 with can removing simultaneously, can take out mounting bracket 3 and clear up jar 4 when needing to add the sample in to clearing up jar 4, avoided because the condition that the space undersize of heating chamber 11 is difficult to the operation.

In this embodiment, the pressure relief device 6 includes a valve seat 61 fixed on the upper end of the protection cover 42, an upper cavity 62 and a lower cavity 63 are provided in the valve seat 61, the bottom of the lower cavity 63 is communicated with the tank 41, specifically, a first through hole 68 communicated with the lower cavity 63 is provided at the bottom of the valve seat 61, a second through hole 421 is provided on the protection cover 42 corresponding to the first through hole 68, and the first through hole 68 is communicated with the second through hole 421.
