The invention discloses an automatic steel disc placing machine, which comprises a bracket, wherein the bracket is partitioned into three regions including a plastic absorption box accommodating region, a steel disc supply region and a steel disc fine positioning region in sequence; a guide rod which spans the three regions is arranged above the bracket; a sliding workbench is fixed on the guide rod through a linear bearing; and the sliding workbench is connected with an air cylinder which is fixed on the bracket and is used for driving the sliding workbench to move in a reciprocating way among the three regions along the guide rod. A steel disc is placed into a plastic absorption box, is accurately positioned secondly, and is placed into a die through a mechanical hand, and an entire process is performed automatically, so that labor cost is saved, the molding period is shortened, yield is increased, and the appearance quality of the steel disc is also ensured.

The invention relates to the aluminum electrolytic cell technical field, in particular relating to a protective cell-shutting method of an aluminum electrolytic cell. The method aims to solve the problems of cracking, deformation and doming up, etc. caused by an inner lining directly exposed in the air during the prior cell shutting, and comprises the following steps that: (1) part aluminum liquid inside an electrolytic cell is pumped out at first; (2) then, part electrolyte liquid inside the electrolytic cell is taken out; (3) an anode is put into the aluminum liquid and is raised after all aluminum liquid is pumped out, and thermocouples are distributed inside the electrolytic cell; (4) the surface of the anode is provided with an alumina heat-preservation material, and a feeding port and an aluminum outlet are sealed closely; moreover, a cell cover plate is covered; (5) a purifying smoke evacuation pipe is closed, and rockwool is used to cork up a side heat dissipation hole of a basin and to carry out bottom heat preservation; a factory building, a trench window and an air grid section are closed, and a window inside a closed workshop is closed; and (6) when temperature inside the electrolytic cell is lowered to normal temperature, cell shutting is completed. The protective cell-shutting method ensures reasonable gradient lowering of the temperature of an electrolytic cell inner lining, and reduces inner lining damage caused during cell shutting; meanwhile, the method has better anodic protection, strong commonality, simple operation and outstanding effects, and can continue to be used.

The invention belongs to the technical field of material separation, and discloses a fast and high-efficiency hydrocyclone, which includes a cyclone body, a flushing water distributor and a deflector, and the flushing water distributor and the deflector are respectively connected with the hydrocyclone on the cyclone body. The bottom covers are connected by welding, and the deflector is symmetrical to the center of the cylindrical cavity on the cyclone body and tangent to the bottom flow tube on the cyclone body. The material is fed in from the feed port and performs a spiral movement in the cyclone. When the particles move to the bottom of the cyclone, under the action of the upward flushing water, the fine particles are taken out and enter the internal cyclone. Under the action of the plate, the separated coarse particles are quickly diverted to the bottom flow port and discharged on the basis of the original rotary motion. The invention utilizes the principle of fluidization to strengthen the internal flow field effect of the hydrocyclone, reduces the amount of fines contained in the bottom flow, and greatly improves the separation efficiency of wide-grade materials; meanwhile, the residence time of coarse particles is reduced, and the processing capacity of the hydrocyclone is further improved .

The invention discloses a silvering solution pre-dissolving process. The process comprises the following steps: adding pure water into a dissolving tank, starting a heater arranged in the dissolving tank and a circulating pump arranged on the dissolving tank; then adding potassium cyanide into the dissolving tank; under the circulating stirring action of the circulating pump, adding silver cyanide after potassium cyanide is dissolved fully into water; injecting the dissolved liquid medicine into a storing tank through a liquid outlet pipeline, a valve and an extracting pump which are arranged on the dissolving tank; after the liquid medicine is injected into the storing tank, starting the heater and a liquid medicine circulating pump which are arranged in the storing tank; introducing the liquid medicine in the storing tank into a titrating tank, and then starting the circulating pump and the heater which are arranged in the titrating tank, then starting a titration metering pump so as to add the liquid medicine into a plating bath with an appointed flow rate due to the adoption of the titration metering pump. Due to the adoption of the process, the thickness of a silver layer on the surface of a silvered product can be uniform without salient points, and furthermore, a large amount of silvering raw materials can be saved.
