Abstract
The utility model relates to a drying and vacuumizing treatment device of special gas cylinders. The device is mainly composed of a gas cylinder drying oven, a heating tube, a steel cylinder fixture, a vacuumizing pump and an electric heating controller. The heating tube and the steel cylinder fixture are arranged in the gas cylinder drying oven, the steel cylinder fixture and the heating tube are connected, the heating tube is connected with the vacuumizing pump through a vacuumizing pipeline, and the heating tube is connected with the electric heating controller. A switch valve and a pressure gauge are arranged on the vacuumizing pipeline. Through the device, heating and vacuumizing can be conducted at the same time, the vacuum degree can be greatly increased, the water content index can be controlled, and thus the precision of prepared special gas is improved. Through the device, two to eight gas cylinders different in volume and mass can be treated at a time, and thus the production efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of special gas gas cylinder and is dried and vacuumizes treating apparatus.
Background technology
After gas cylinder by hydrostatic pressure test, moisture and air are contained in inside, can not meet the requirement before special gas preparation, need to be dried and vacuumize processing to gas cylinder.The existing device that is dried and vacuumizes processing for special gas gas cylinder, can reach aridity and vacuum that regulation requires.But the temperature on panel will be leaned on manual setting, the gas cylinder processing time will be leaned on manual record; Whole device sealing property is not fine; The limited amount of the gas cylinder of the various volumes of every batch processing; The gas cylinder of different size can not be processed simultaneously; Whole device is processed gas cylinder by processing in batches, can not process separately.In the time processing gas cylinder, only depend on the numerical value showing on Pressure gauge to be confirmed whether to be extracted into certain vacuum, this exists certain limit.Based on above-mentioned a variety of causes, be badly in need of a covering device and can solve an above difficult problem simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of special gas gas cylinder and is dried and vacuumizes treating apparatus, and 4 kinds of not isometric gas cylinders of energy single treatment, have improved production efficiency greatly, have ensured the security of processing procedure.
The technical solution of the utility model is:
This device is mainly made up of gas cylinder baking oven, heating tube, steel cylinder fixture, vacuum pumping pump, electrical heating controller; Heating tube, steel cylinder fixture are placed in gas cylinder baking oven, and steel cylinder fixture is connected with heating tube, and heating tube is connected with vacuum pumping pump by vacuum lead, and heating tube is connected with electrical heating controller.
On vacuum lead, be provided with switch valve and Pressure gauge.
On heating tube on heating tube on the heating tube between B and C steel cylinder fixture, between D and E steel cylinder fixture, between F and G steel cylinder fixture, switch valve is set.
Special gas gas cylinder of the present utility model is dry and vacuumize treating apparatus, can limit heating edge vacuumize greatly gas clean-up and control water content index, thereby the accuracy of the special gas that raising is prepared; By use this device once can process the gas cylinder of the individual not co-content of 2-8 and quality simultaneously, greatly improve production efficiency, save the time; By the electrode pressure table connecting, can monitor at any time the process of processing, in the time that vacuum has been processed the value requiring, vavuum pump stops automatically, has ensured security and the validity of processing procedure, has further guaranteed overall tightness and the stability of device.This device is mainly used in the processing of the special gas gas cylinder that precision prescribed is higher.
Brief description of the drawings
Fig. 1 is that special gas gas cylinder of the present utility model is dried and vacuumizes treating apparatus structural representation.
In figure: 1-vacuum pumping pump, 2-steel cylinder fixture, 3-switch valve, 4-electrode pressure table, 5-switch valve, 6-thermometer, 7-electric-controlled switch, 8-electrical heating controller, 9-heating tube, 10-gas cylinder baking oven, 11-vacuum-pumping tube.
Detailed description of the invention
As shown in Figure 1, special gas gas cylinder of the present utility model is dried and vacuumizes treating apparatus and is mainly made up of gas cylinder baking oven 10, heating tube 9, steel cylinder fixture 2, vacuum pumping pump 1, electrical heating controller 8; Heating tube 9, steel cylinder fixture 2 are placed in gas cylinder baking oven 10, and steel cylinder fixture 2 is connected with heating tube 9, and heating tube 9 is connected with vacuum pumping pump 1 by vacuum lead 11, and heating tube 9 is connected with electrical heating controller 8.On vacuum lead, be provided with switch valve 3 and electrode pressure table 4.On heating tube on heating tube on the heating tube between B and C steel cylinder fixture, between D and E steel cylinder fixture, between F and G steel cylinder fixture, switch valve 3 is set.Electrical heating controller is provided with thermometer 6 and electric-controlled switch 7.
Through vacuum pumping pump, gas cylinder internal moisture and air are all extracted out and reached requirement.This device is for various not co-content gas cylinders (comprising 40L/8L/4L/2L), can 8 gas cylinder of single treatment, and comprising 2 40L gas cylinders, 2 8L gas cylinders, 2 4L, 2 2L gas cylinders.Also can pass through actual needs, switch valve is processed separately not isometric gas cylinder.Pending gas cylinder is connected in device, switches on power, set temperature to 120 DEG C, and starting vavuum pump, baking limit, limit vacuumizes that (take out after 45 minutes, vacuum meets the requirements, vavuum pump electricity connects Pressure gauge to be stopped automatically), record the time, after 2 hours, gas cylinder dry run finishes.Whole gas cylinder processing procedure finishes.Its rational in infrastructure, strong adaptability, without phenomenons such as run, drip, leak, economical and practical, safety.
