Description
Technical Field
[0001] The invention relates to the technical field of liquid phase reaction generation materials, in particular to liquid phase reaction generation equipment. Background Art
[0002] The existing technical solutions in this field are as follows: Liquid phase reaction equipment for materials (dispensing room). The main frame of the equipment is a dome-shaped square bottom box. At the junction of the dome and the square bottom, C-shaped steel (mainly used to install bearings and support rollers) is installed. There are 8 boxes in total, and each box can install 40 transmission rollers (10 rollers form a group, and each group has a reducer driving roller and a driven transmission roller. The driving end of the roller is equipped with a helical gear transmission. To ensure the consistent rotation direction of the rollers, a set of intermediate gear transmission mechanism is installed between every two rollers, which is mainly composed of intermediate gear shafts, bearings and helical gears); the carrier of the liquid phase reaction of materials is a material box (with a four-sided boss shape), and 8 boxes can hold a total of 32 material boxes; in addition to the 8# box, this equipment is equipped with a sprocket lifting sealing door at the 1# inlet, 8# outlet, between 1-2#, and between 7-8#, which serves as a partition During the absolute liquid phase reaction, it reduces the leakage of acidic and alkaline gases and granular materials; the acid is discharged from the acid outlet at the driving end through the square bottom (slanted bottom), and the acidic and alkaline gases generated by the liquid phase reaction are extracted through the exhaust system. At the same time, safety valves such as flame-retardant breathing valves, balancing valves, air-breaking valves, and butterfly valves are equipped according to the box pressure to prevent the dome box from deforming due to excessive instantaneous pressure; when this equipment is working, the 1# box inlet door is opened (2# door is closed), and 4 material boxes enter at the same time, then the 1# door is closed (2# door is opened), and the material box enters the 2nd door, and then the 4 groups of feeding pipes of 2# feed the 4 material boxes at the same time, and then the interval feeding time is controlled according to the volatilization reaction time (production rhythm) required by the material, and then all the material boxes move forward in turn, and finally discharge at 8# to complete the entire material delivery process.
[0003] Export transition roller table. Used to place the material boxes coming out of 8# and then transport them forward to the export elevator. Its main function is to serve as a temporary placement point for the material boxes to speed up the production rhythm.
[0004] Export elevator: It is used to lift the material boxes coming from the export transition roller table to the upper floor, playing the role of transferring the material boxes.
[0005] Tilting crusher. The special transition roller table of the tilting crusher transfers the material box lifted from the outlet to the tilting machine. The tilting machine turns 180° and pours the material into the coarse crusher. After the coarse crushing by the reamer and spiral, the material is transported to the next process by the feeding spiral.
[0006] Turnover trolley. The turnover trolley is equipped with a roller table. At the same time, in order to speed up the entire production rhythm, a transition roller table dedicated to the turnover trolley is installed near the exit elevator. The turnover trolley transfers the empty material box after flipping and unloading through the flip transition, exit elevator (with roller table), and turnover transition roller table to the turnover trolley. The exit elevator returns to the next layer and continues to lift the next material box. The turnover trolley then transports the empty material box to the import elevator (with roller table), and then returns to the exit elevator side to transfer the next material box.
[0007] Imported elevator. The imported elevator transfers the empty material boxes on the turnover trolley to the car roller table, then descends, and then transports them to the import transition through the roller table.
[0008] Import transition: The import transition temporarily stores empty boxes, and then when the import door of the material delivery room equipment is opened next time, 4 empty boxes are put in at a time. The above realizes the recycling of empty boxes.
[0009] PLC control system. This system requires manual control of the movement of the material box, and the central control operator needs to perform inching control according to the beat. This equipment has certain defects; 1. The chain-lifting sealed door has a complex structure and heavy weight, and the chain door is prone to failure; 2. The 32 material box positioning sensors have a complex structure, require a large amount of material, and are prone to metal contamination (the sensor sensing device and the metal of the material box frame are in contact and worn); 3. Except for the equipment in the material delivery room, the other process equipment is not covered with protective covers, which will cause the leakage of acidic and alkaline gases and particles, and impurities in the external environment will contaminate the materials; 4. The production pace is slow and semi-automatic control is adopted.
