Description

Technical Field

[0001] This utility model relates to the field of heating device technology, specifically to a soil testing digestion reaction heating device. Background Technology

[0002] Soil digestion and heating is the core step in the soil pretreatment process. Its fundamental purpose is to break down the complex physicochemical structure of the soil and transform the target analytes into a form that can be accurately detected by instruments, thus clearing obstacles for subsequent analysis.

[0003] When digesting and heating the soil, multiple soil samples are first placed in multiple crucibles, then the digestion solution is added, and then the crucibles are heated on a heating plate. After heating to a certain degree, other solutions are then dripped into several crucibles in sequence to react with the soil inside, and finally the soil is digested into a detectable form.

[0004] Because different solutions need to be added repeatedly to react with the soil during the soil digestion and heating process, the operator needs to remove the crucible containing the soil from the heating plate multiple times to add the solution. Sometimes, when testing different types of soil, multiple types of soil are placed in multiple crucibles. When adding the solution, the operator needs to remove several crucibles one by one, which is quite troublesome. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 5A soil testing digestion reaction heating device includes a heater 1, a lifting assembly, a fixing rod 2, a first clamping half-ring 3, and a second clamping half-ring 5. The lifting assembly is mounted on the heater 1 via a sliding separation assembly to move a crucible containing soil away from the heater 1. There are two fixing rods 2, both mounted on the lifting assembly. There are two sets of first clamping half-rings 3, each set containing several first clamping half-rings 3. The two sets of first clamping half-rings 3 are fixedly mounted between the two fixing rods 2 via two connecting rods 4. There are two second clamping half-rings 5, each set containing several second clamping half-rings 5. The two sets of second clamping half-rings 5 ​​are mounted between the two fixing rods 2 via two moving assemblies.

[0026] like Figure 5 As shown, when heating and digesting soil, the staff first takes several crucibles and places different types of soil into them. Then, the solution before heating is added, and the crucibles are placed on the heating plate of heater 1. Next, the moving component drives the second clamping half ring 5 to contact the first clamping half ring 3, thereby clamping the crucibles. The moving component includes a moving rod 15 and a fixing frame 16. The moving rod 15 is slidably installed on the side of the two fixing rods 2, and several second clamping half rings 5 ​​are fixedly installed on the side of the moving rod 15. The fixing frame 16 is U-shaped. Limiting holes are opened at the top of the moving rod 15 and the fixing rods 2, and the fixing frame 16 can be detachably installed in the limiting holes.

[0027] Specifically, the sliding rod 15 is positioned at the fixed rod 2, causing the second clamping half-ring 5 to fit against the first clamping half-ring 3, thereby clamping the crucible. It should be noted that the first clamping half-ring 3 and the second clamping half-ring 5 are specifically designed to fit the crucible, and soft pads can be installed on the inner walls of the first clamping half-ring 3 and the second clamping half-ring 5 to protect the outer wall of the crucible. After clamping, the fixed bracket 16 is inserted into the limiting holes of the two fixed rods 2 to fix the sliding rod 15 on the fixed rod 2. Then, the heater 1 is activated, and the internal heating wire of the heater 1 generates heat to heat the heating plate at the top of the heater 1. The bottom of the crucible is placed on the heating plate to heat the soil inside.

[0028] like Figure 2 , Figure 3 and Figure 4As shown, when the temperature reaches a certain level, such as after the soil emits steam, and it is necessary to add other solutions, the crucible needs to be removed from the heating plate to prevent the internal material from boiling during the addition of solutions. At this time, the crucible is lifted by a lifting assembly, and then moved away from the heater 1 by a sliding moving assembly. The sliding moving assembly includes a slide rail 6, a sliding plate 7, and a blocking assembly. Slide rails 6 are fixedly installed on both sides of the heater 1, and two sliding plates 7 are slidably installed within the two slide rails 6. The blocking assembly is located on the side of the heater 1 and includes a rotating shaft 8 and a blocking rod 9. The rotating shaft 8 is rotatably installed on the side of the heater 1 via a mounting plate, and the blocking rod 9 is L-shaped. One end of the blocking rod 9 is fixedly installed on the side of the rotating shaft 8. The lifting assembly includes a support cover 10, a reciprocating screw 11, a throttle 12, and a sliding assembly. Support covers 10 are fixedly installed on both sliding plates 7. The reciprocating screw 11 is rotatably installed in one of the support covers 10, and a matching crescent slider 17 is installed on the reciprocating screw 11. The throttle 12 is coaxially connected to the reciprocating screw 11. The sliding assembly is located in the other support cover 10. The sliding assembly includes a sliding rod 13 and a sliding block 14. The sliding rod 13 is fixedly installed in the other support cover 10, and the sliding block 14 is slidably installed on the sliding rod 13. Fixing rods 2 are fixedly installed on the sides of both the sliding block 14 and the crescent slider 17.

[0029] Specifically, the operator rotates the handle 12, which drives the reciprocating screw 11 to rotate inside the support cover 10. At this time, the crescent-shaped slider 17 moves upward on the reciprocating screw 11. Under the connection of the fixed rod 2 and the connecting rod 4, it drives the sliding block 14 to move upward on the sliding rod 13, thereby driving several first clamping half-rings 3 and second clamping half-rings 5 ​​to move upward, thus clamping several crucibles upward. Then, the blocking frame is rotated, and the sliding plate 7 is moved to slide the support cover 10 to the other side of the heater 1, so that the crucibles are away from the heater 1. After the crucibles are moved away, the operator adds the solution to several crucibles in sequence. When heating again, the crucibles are moved back, and the blocking frame is rotated. It should be noted that when the side of the blocking frame is in contact with the side of the sliding plate 7, the sliding plate 7 moves to the outermost end of the slide rail 6, and at this time the crucibles are above the heater 1. Thus, the blocking frame and the slide rail 6 can block the two sides of the support cover 10.

[0030] It should be added that the shape design of the crescent slider 17 matches the helical groove of the reciprocating screw 11. When the reciprocating screw 11 rotates, the side wall of the helical groove will generate an axial thrust on the crescent slider 17 embedded therein. The crescent slider 17 can move along the axial trajectory of the reciprocating screw 11, thereby moving up and down. When the crescent slider 17 reaches the end of the reciprocating screw 11, the crescent slider 17 will smoothly transition to the reverse helical groove, thereby realizing reciprocating movement. This is a well-known technology and will not be described in detail here.

[0031] Working principle: When this soil testing and digestion reaction heating device digests and heats the soil, the operator first takes several crucibles and places different types of soil into them. Then, the solution before heating is added, and the crucibles are placed on the heating plate of heater 1. Then, the sliding rod 15 is moved to the position of the fixed rod 2, so that the second clamping half ring 5 fits against the first clamping half ring 3, thereby clamping the crucible. After clamping, the fixed frame 16 is inserted into the limiting holes of the two fixed rods 2 to fix the sliding rod 15 on the fixed rod 2. Then, the heater 1 is started, and the bottom of the crucible is placed on the heating plate to heat the soil inside.

[0032] When the temperature reaches a certain level and other solutions need to be added, the operator turns the handle 12, which drives the reciprocating screw 11 to rotate inside the support cover 10. At this time, the crescent-shaped slider 17 moves upward on the reciprocating screw 11, and under the connection of the fixed rod 2 and the connecting rod 4, it drives the sliding block 14 to move upward on the sliding rod 13, thereby driving several first clamping half-rings 3 and second clamping half-rings 5 ​​to move upward, thus clamping several crucibles upward. Then, the blocking frame is turned and the sliding plate 7 is moved to slide the support cover 10 to the other side of the heater 1, so that the crucibles are away from the heater 1. After they are away, the operator adds the solution to several crucibles in sequence. When heating again, the crucibles are moved back and the blocking frame is turned to block the support cover 10. At this time, when adding the solution to the crucibles a second time, several crucibles can be moved synchronously without having to be removed one by one.

[0033] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
