Abstract

The invention discloses a digestion tube oil-bath placing device. The digestion tube oil-bath placing device comprises a main body framework with an opening in lower end, wherein a small grid chassiswhich is consistent with the main body framework is arranged in the main body framework; the small grid chassis can be movably connected onto the main body framework up and down; the side surface of the small grid chassis is connected with a pull rope; the other end of the pull rod passes through a buckling ring on the top of the main body framework and then is connected with a hanging ring; aftermoving, the hanging ring can be hung on a hanger; the hanger is fixedly mounted on the middle upper part of the main body framework; the top of the main body framework is equipped with a large grid chassis. The digestion tube oil-bath placing device can prevent the bottom of a digestion tube from being in contact with the bottom of an oil bath, and increases heating temperature uniformly; when boiling reagents such as sulfuric acid are added into the digestion tube, blasting caused by uneven heating is avoided, so that using safety is greatly improved; a lifting device which consists of the pull rope, the hanging ring, the hanger and the buckling ring is convenient and quick to operate, is simple in structure and is low in cost; the suspended digestion tube is better in ventilating effect, can quicken quick drop of oil liquid, and is convenient for cleaning the digestion tube.

Description

technical field [0001] The invention relates to a device for placing an oil bath for digestion tubes, and belongs to the technical field of oil bath equipment for digestion tubes. Background technique [0002] In the existing oil bath device, when using the digestion tube oil bath, the digestion tube is usually placed in the placement frame, and the placement frame is placed in the oil bath device for oil bath, but the digestion tube will touch the bottom of the oil bath device, There is a danger of the digestion tube bursting due to excessive local temperature, and the use safety is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device for placing an oil bath for a digestion tube to solve the above-mentioned problems in the prior art. [0004] The technical solution adopted by the present invention is: a device for placing an oil bath for digesting pipes, including a main frame with an open lower end, ...
