Description

Technical Field

[0001] The utility model relates to the field of deoxidizers, in particular to a micro-positive pressure deoxidizer. Background Art

[0002] Deoxygenator is a kind of equipment, which is mainly used to reduce the oxygen concentration in the gas conditioning storage to maximize the preservation energy efficiency. It achieves the purpose of preservation by quickly reducing the oxygen content in the gas conditioning storage to create a low oxygen environment. The working principle of the deoxygenator is based on Henry's law, that is, the solubility of gas in liquid is proportional to the pressure of the liquid surface. By reducing the pressure on the water surface, the gas dissolved in the water is precipitated, thereby removing the gas in the water;

[0003] Most of the deoxidizers in the prior art have fixed structures, and the upper deoxidation tower body is supported and placed by a bottom bracket. However, it is generally not convenient to move and adjust, and can only be placed in a specified position by external lifting equipment. It is inconvenient to move the position later, which affects the flexibility of the device. At the same time, it does not have the ability to easily disassemble and assemble the tower body. When maintenance is required on one side of the tower body, multiple sets of bolts need to be removed by tools. The operation is time-consuming and labor-intensive, which greatly reduces the efficiency of the later maintenance of the device. Therefore, we need to upgrade and transform the existing technology to overcome its problems and shortcomings. Utility Model Content

[0025] By rotating the bidirectional screw 96, the central shaft 95 is driven to move in opposite directions. The central shaft 95 drives the lower push rod 92 and the upper push rod 94 to rotate in opposite directions. The cooperation of the lower push rod 92 and the upper push rod 94 can push the base plate 7 and the universal wheel 8 to rise and fall, thereby facilitating the device to move its position or to retract and stably place the universal wheel 8 after movement, thereby effectively improving the flexibility of the device.

[0026] Preferably, the mounting assembly 6 includes a plug-in board 61, a gear 62 and a rack rod 63 are arranged inside the outer side of the plug-in board 61, the rack rod 63 is meshed with the gear 62, a knob 64 is arranged at the outer end of the rack rod 63, the plug-in board 61 is plugged into the plug-in slot 21, the outer end of the rack rod 63 passes through the plug-in board 61 and is plugged into the side wall of the fixing frame 2, the plug-in board 61 and the side wall of the fixing frame 2 are both provided with positioning holes 22, and positioning pins 23 are correspondingly plugged into the positioning holes 22;

[0027] The plug-in plate 61 and the plug-in slot 21 cooperate to facilitate the installation of the A tower body 3 and the B tower body 4. The knob 64 is used to control the rotation of the gear 92, thereby driving the rack rod 63 to move. The rack rod 63 is used to limit the plug-in plate 61. The positioning hole 22 and the positioning pin 23 cooperate to facilitate the secondary limiting and fixing of the plug-in plate 61.

[0028] The use principle and use process of the utility model are as follows: when in use, firstly, in the first cycle, micro gas is supplied into the fresh-keeping warehouse through the high-pressure blower 5, and the nitrogen gas adsorbed by the carbon molecular sieve is supplied into the fresh-keeping warehouse. There are over-positive pressure and negative pressure safety valves on the warehouse body to control the pressure within 0-5PA. Then, in the second cycle, the gas returns to the A tower body 3 for adsorption and then the required nitrogen is sent into the warehouse. At the same time, the B tower body 4 analyzes the oxygen and sends it to the outside. Then, the gas returns to the B tower body 4 for adsorption operation, and the oxygen is analyzed by the A tower body 3. The above operation is repeated for periodic cycle operation, which can effectively solve the problem of shrinkage and damage of the warehouse body caused by negative pressure in the fresh-keeping warehouse. When the device needs to be moved, the central shafts 95 on both sides can be driven to move outward by rotating the bidirectional screw 96. The spindle 95 drives the lower push rod 92 and the upper push rod 94 to rotate in opposite directions. The cooperation of the lower push rod 92 and the upper push rod 94 can push the base plate 7 and the universal wheel 8 down, which is convenient for driving the device to move its position. The moving shaft reverses the bidirectional screw 96 to drive the base plate 7 to rise, so that the side bracket of the fixed frame 2 can be in contact with the ground. When it is necessary to inspect and maintain the A tower body 3 or the B tower body 4, the knob 64 can be used to control the rotation of the gear 62. The gear 62 drives the two sets of rack rods 63 to retract into the plug-in plate 61, and then the locating pin 23 is pulled out from the locating hole 22. At this time, the plug-in plate 61 together with the upper end A tower body 3 or B tower body 4 can be separated from the fixed frame 2, which is convenient for local inspection, maintenance or replacement without removing multiple sets of bolts.
