[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0027] Example 1

[0028] like Figure 1-3As shown, an all-round heating digestion and acid removal instrument comprises a shell 1, a heating tank 2 and an upper cover 3; the heating tank 2 is sleeved inside the shell 1, the top of the shell 1 is open and provided with an upper cover 3, the upper cover 3 comprises an outer frame 31 and a cover plate 3 arranged on the outer frame 31, and a plurality of uniformly arranged first plug holes 321 are arranged on the cover plate 32; a heating sleeve 21 corresponding to the first plug holes 321 is arranged at the bottom of the heating tank 2, an insulating porcelain sleeve 23 is also arranged on the inner side wall of the heating tank 2, and a heating wire 22 penetrates into the heating tank 2 through the insulating porcelain sleeve 23 from a side provided with the insulating porcelain sleeve 23 and is wound around the outer periphery of the heating sleeve 21.

[0029] Specifically, the heating sleeves 21 can be arranged in a matrix, and the heating sleeves are provided with an even number of columns, each two columns forming a group, and an insulating porcelain sleeve 23 is provided on the inner wall of the heating tank corresponding to each column; the heating sleeves in the same group are wound with the same heating wire, that is, an electric heating wire passes through one of the insulating porcelain sleeves, and the electric heating wire is wound around the two columns of heating sleeves in turn and passes through the other insulating porcelain sleeve. Multiple heating wires can be easily inspected and replaced, and the temperature of multiple heating wires is controlled by the same temperature controller.

[0030] More specifically, Figure 3 As shown, there are 3 groups, 2 rows in a group, and the heating wires are wound around the heating sleeve like a twist, so as to achieve 360-degree fully surrounded heating.

[0031] Specifically, a sensor bracket 24 for placing a temperature sensor is further provided on the edge of the heating tank 2 .

[0032] When in use, the test tube 6 is inserted into the corresponding heating sleeve through the first jack. A heating sleeve is provided at the bottom of the heating tank of the acid-removing instrument, and a heating wire is wound around the outer circumference of the heating sleeve, so that each heating sleeve uniformly and 360° all-round heats the test tube, which improves the heat utilization rate and is conducive to improving work efficiency.

[0033] Example 2

[0034] like Figure 4 As shown, an all-round heating digestion and acid removal instrument is provided. Based on the above embodiment 1, the thickness of the cover plate 32 is less than the thickness of the outer frame 31, and the upper surface of the outer frame 31 is higher than the upper surface of the cover plate 32, so that the outer frame 31 and the cover plate 32 form a groove 33.

[0035] Exemplarily, a vertically arranged guide rod 5 is provided in the heating groove 2, a support plate 4 is slidably sleeved up and down on the guide rod 5, a second socket 42 corresponding to the first socket 321 is provided on the support plate 4, the size of the support plate 4 is the same as the size of the groove 33, the support plate 4 can be inserted into the groove 33, and a handle 41 is also provided on the support plate 4, which can facilitate lifting the support plate.

[0036] Specifically, there are four guide rods 5 respectively located at the four top corners of the heating tank 2. The guide rods 5 are also provided with support pins 51 for holding the support plate 4. The distance between the pin holes for inserting the support pins on the guide rods 5 and the upper surface of the upper cover is greater than the length of the test tube.

[0037] After digestion, the test tubes need to be taken out for natural cooling, but it is inconvenient to take out the test tubes because they are hot. The test tube mouths are stuck in the second plug hole of the support plate. All the test tubes can be taken out at the same time by holding the handle and pulling the support plate upwards. When pulling the support plate upwards, the support pin must be removed. When the support plate rises above the pin hole where the support pin is inserted, stop pulling the support plate, then insert the support pin into the corresponding pin hole, lower the support plate, and place the support plate on the support pin.

[0038] Example 3

[0039] like Figure 5 As shown, an all-round heating digestion and acid removal instrument is different from the above-mentioned embodiment 2 in that a guide rod 5 is provided and located at one of the top corners of the heating tank 2, and the support plate 4 is sleeved on the guide rod 5 and can rotate around the guide rod 5.

[0040] When cooling is required, lift the support plate upwards to make the test tube leave the second insertion hole, then rotate the support plate until the test tube is no longer facing the upper cover, and then move the support plate downwards to make the support plate rest on the upper cover.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
