Further, described top discharge nozzle comprises vertical tube and horizontal tube, and a plurality of discharge openings distribute below described horizontal tube.
Further, the diameter of described discharge opening is 5 millimeters.
Further, a bottom discharge pipe is also set, one end mouth of pipe of described bottom discharge pipe is arranged on the below of described coarse filtration sieve plate, and its other end is communicated with high-order transition pot.
Further, on described dissolving pan pot body, be provided with a plurality of observation visors.
Further, below described dissolving pan pot body, be also provided with slag notch.
Further, on described dissolving pan pot body, be provided with thermometer.
The dissolving pan using in this rosin production link and dissolving method thereof are compared with existing dissolving pan, have following beneficial effect:
(1) the present invention is due to by arranging top discharge nozzle at oxalic acid solution layer top, make only dispensing liquid rosin of top discharge nozzle, and oxalic acid solution is continued to be retained in dissolving pan, thereby the oxalic acid solution in dissolving pan can reuse, reduced on the one hand the use amount of oxalic acid, also avoid oxalic acid solution to be directly discharged in environment, caused environmental pollution simultaneously.
(2) the present invention is due to liquid rosin is directly exported by top discharge nozzle, changed the pattern that conventional liquid rosin extrudes by bottom discharge pipe, the possibility of having avoided liquid rosin and solid impurity layer to come in contact, thereby the rosin quality obtaining in high-order transition pot is improved greatly, in the impurity of simultaneously discharging, the content of rosin also reduces greatly, has greatly improved rosin conversion ratio.
(3) the present invention also due between the oxalic acid in dissolving pan and rosin for exothermic reaction, when retaining oxalic acid solution, also preserved heats a large amount of in dissolving pan, for again reacting, provide energy, reduced the demand of vapours, reduced carbon emission.
