Description

Technical Field:

[0002] The utility model relates to a constant-temperature gas shaking device, which is particularly suitable for the uniform treatment of mixed gas in a steel cylinder and the treatment of the steel cylinder before filling high-purity electronic special gas. Background Art:

[0004] Before filling high-purity gas, the filling steel cylinder needs to be strictly treated to ensure the purity of the high-purity gas in the cylinder. In addition to the basic pressure test for leakage and vacuum pumping, the steel cylinder treatment steps also require filling a small amount of the high-purity gas to be filled into the cylinder for passivation, so as to carry out the impurity gas adsorbed on the inner wall of the cylinder.

[0005] During the passivation treatment process, the mixing treatment is very important. The existing mixing methods include heat treatment, special treatment, and the method of rolling the gas cylinder. The method of rolling the gas cylinder is widely used for shaking the mixed gas. However, the existing rolling bottle machine still has deficiencies when applied to the passivation of the steel cylinder before filling high-purity electronic special gas, such as the complex shaking mechanism and high manufacturing cost. In addition, for liquefied electronic special gas, the steel cylinder usually needs to be additionally heated. On the one hand, it is to increase the gas phase, and on the other hand, it helps the impurity gas adsorbed on the inner wall of the cylinder to desorb, and finally is discharged with the passivation gas to reduce the impurity content in the cylinder. Summary of the Invention:

[0007] In view of the above problems, the purpose of the utility model is to provide a constant-temperature gas shaking device, which is reasonably designed and is conducive to realizing the uniform treatment of the gas in the steel cylinder.

[0008] The utility model is realized by the following solutions:

A plurality of parallel rotating shafts and bearing seats for supporting the rotation of the rotating shafts are arranged in the cabinet body. A plurality of coaxially arranged rollers are fixedly provided on the rotating shafts. An accommodating space for supporting and placing the steel cylinder is formed between two adjacent rotating shafts. One of the plurality of rotating shafts extends out of the cabinet body and is connected to a motor arranged outside the cabinet body for transmission. A telescopic cylinder for driving the cabinet body to be in a horizontal or vertical working position is arranged between the frame and the turning frame.

[0010] Preferably, the rotating shaft driven by the motor is the active rotating shaft, and the other rotating shafts are passive rotating shafts. The active rotating shaft is located in the middle of the cabinet body, and the passive rotating shafts are symmetrically arranged on both sides of the active rotating shaft respectively. The passive rotating shafts are driven to rotate passively by the rotating steel cylinder.

[0011] Preferably, a heating chamber is provided on the back of the cabinet body, and a heater is provided in the heating chamber.

[0015] The working principle of the constant-temperature gas shaking device of the present utility model: In the initial state, the telescopic rod of the telescopic cylinder is in the extended state, so that the cabinet body is in the horizontal working position, and there is no steel cylinder in the cabinet body at this time; when the equipment is ready for work, the telescopic rod of the telescopic cylinder contracts, so that the cabinet body is in the vertical working position. At this time, the bottom of the cabinet body is close to the ground, and the operator moves the steel cylinder into the cabinet body. After the steel cylinders are placed between every two rotating shafts in the cabinet body, the telescopic rod of the telescopic cylinder extends, so that the cabinet body returns to the horizontal working position again. The motor and the driving rotating shaft are started to rotate. The rotation of the driving rotating shaft drives the steel cylinders on its two sides to rotate, and then drives the passive rotating shafts on the other side of the steel cylinders to rotate, thereby completing the rotation of each steel cylinder; after working for a certain period of time, the rotation of the motor is stopped, and the telescopic rod of the telescopic cylinder contracts, so that the cabinet body is in the vertical working position.
