Description
Technical Field
The utility model relates to an automatic heating digestion device belongs to experiment treatment instrument technical field.
Background
Some solid samples need to be digested before they can be tested. Among them, thermal digestion is a more common digestion method. There are two main ways of heat elimination, water bath heating and microwave heating. The water bath heating is more in use due to the convenience. However, digestion by water bath heating also has some disadvantages. Most importantly, the boiling point of water is 100 ℃, so the highest temperature of water bath heating, namely 100 ℃, cannot be increased continuously.
At present, oil bath heating is also used in the chemical field, and the heating temperature is higher than the water bath heating temperature. The oil bath heating can use the oil bath heating pan, because the heating pan is a comparatively ripe instrument. However, there are also some points to be improved when digestion by heating is used. For example, the liquid level of the heat transfer oil in the oil bath heating pan is not easily adjusted, and the test tube cannot be optimally heated as needed. When the sample is heated and digested, the test tube can not be heated excessively, and the digestion efficiency can not be low due to the insignificant heating effect.

The present invention will be described in further detail with reference to the following drawings and specific embodiments:
the utility model discloses an automatic heating digestion device is an instrument device that is used for heating the sample and clears up. The device is based on an oil bath heating pan in the prior art, and is improved in adaptability. We used here an HH-SM constant temperature oil bath from Kai navigation instruments, Inc., of Changzhou. The following examples are modifications based on the oil bath pan, and the modifications will be described in detail below.
The utility model discloses at first utilized the oil bath heating pot among the prior art, because the higher conduction oil of boiling point is heat conduction heat transfer medium for the oil bath heating pot uses, so compare with water bath heating and have higher heating temperature. As shown in FIGS. 1 and 2, the automatic digestion apparatus mainly comprises an oil bath heating pan 1. A side adjusting cavity 2 is arranged on one side of the oil bath heating pan 1, and an adjusting piston 3 is arranged in the side adjusting cavity 2. The side adjusting cavity 2 is integrally arranged with the main body shell part of the oil bath heating pan 1, in fact, the side adjusting cavity 2 is added on the side of the main body shell of the oil bath heating pan 1, and the side adjusting cavity 2 is communicated with the inside of the oil bath heating pan 1. In the working state, heat conducting oil is filled in the oil bath heating pot 1, and the heat conducting oil can also enter the side adjusting cavity 2. The volume of the side regulation cavity 2 can be changed by the adjusting piston 3 arranged inside the side regulation cavity 2 through the moving position, so that the liquid level of the heat transfer oil in the oil bath heating pot 1 is adjusted, the liquid level of the heat transfer oil is required to be consistent with the height of a sample and a reagent in a test tube or slightly lower by about 1-2 mm, and the test tube is uniformly, quickly and reasonably heated. Some of the devices are provided with an end cover at the upper end of the heating pot.
In this device, an adjusting piston 3 is used, and as shown in fig. 2, the adjusting piston 3 includes a piston head 3-1 and a piston rod 3-2 which fixes one side of the piston head 3-4. And a sealing ring is arranged on the side surface of the piston head 3-1 to ensure the sealing property. The side surface of the piston head 3-1 is connected with the inner wall sliding pair of the side adjusting cavity 2. The piston rod 3-2 extends outwards through the side wall of the side adjusting cavity 2 and further extends to the outside, the piston rod 3-2 is connected with a perforation moving pair on the side wall of the side adjusting cavity 2, and a sealing ring is arranged in the perforation to ensure the sealing performance. The piston rod 3-2 has a part located outside, by means of which the position of the piston 3-1 can be adjusted by the staff.
The device is provided with a lateral adjusting cavity 2 and is matched with an adjusting piston 3 for volume adjustment. In a particular implementation, the lateral adjustment chamber 2 is preferably provided with a rectangular cross-section, and likewise the piston head 3-1 of the adjustment piston 3 is provided with a rectangular shape. The opening of the side edge adjusting cavity 2 is a rectangular hole, and the lower end of the side edge adjusting cavity is flush with the lower end face of the interior of the oil bath heating pot 1, so that the heat conduction oil can smoothly flow.
When the device works, a sample to be heated and digested needs to be placed in a test tube to be heated and digested, and then the test tube is placed in an oil bath heating pot 1. For this purpose, the device is provided with a test tube rack 4 for holding test tubes. As shown in fig. 2, a front opening is provided in the side wall of the oil bath heating pan 1, and a test tube rack 4 is mounted on the front opening. The test-tube rack 4 is the rectangular plate, sets up a plurality of circular ports 7 that can hold the test tube of different diameter specifications on the rectangular plate. Usually, the circular holes 7 on the test tube rack 4 are arranged in a matrix to realize the orderly arrangement of the test tubes. The circular holes 7 are arranged in rows, and the circular holes 7 in the same row have the same diameter. The diameter of the circular holes 7 of different columns may be different. As shown in fig. 3, there are 5 rows of circular holes, the left two rows being of smaller diameter, the middle two rows being of medium diameter, and the rightmost row being of larger diameter. Considering that relatively few applications of large diameter tubes are possible, only one row of large diameter circular holes is provided. The diameter size of specific circular port is according to the specification setting of test tube, and the test tube diameter has multiple specifications such as 10mm, 12mm, 15mm, 18 mm. Can also set up two or three rectangular plate as the test-tube rack, set up the circular port of specification in 2 ~ 3 on every rectangular plate.
When the device works, the liquid level of the heat conducting oil in the oil bath heating pot 1 needs to be adjusted according to the number of samples in the test tube. Therefore, it is necessary to be able to observe the situation inside the oil bath heating pan 1 in real time, especially when adjusting the level of the heat transfer oil. Therefore, a transparent observation window 5 is embedded in the side wall of the oil bath heating pan 1. The transparent observation window 5 is provided with transparent glass and can bear the temperature of heat conduction oil. The juncture of the transparent glass and the side wall of the oil bath heating pan 1 is filled with heat-resistant silica gel to ensure the sealing property.
The test-tube rack 4 in the device is directly placed to the tang in the oil bath heating pan 1 on, and the test-tube rack 4 can take out and also can place into. In order to facilitate the taking and placing of the test tube rack 4, the handle frames 6 are fixedly arranged on two sides of the upper end of the rectangular plate. Preferably, the handle frame 6 is made of wood material, which is not suitable for conducting heat and preventing scald.
The utility model discloses use the oil bath heating pot as the basis, improved the design into new heating digestion device. The device adopts oil bath heating can have higher heating temperature. Through setting up side regulation chamber and adjusting piston, can adjust the liquid level of the conduction oil in the oil bath heating pot to the test tube that makes pending can be heated by even reasonable, thereby improves and clears up efficiency. The device has good use performance in actual use.
