the medium sand with the fineness modulus 3 is manufactured by using the hard material of cobble, the pressure value between two rollers (namely, a movable roller 10 and a fixed roller 6) of a crushing cavity (namely, an inner cavity of a sand manufacturing box body 25) of the sand manufacturing machine is set to be about 8MPa, a motor 3 is 160Kw, the working current of the motor 3 is most appropriate between 70 percent and 100 percent and is lower than the range, the benefit of the sand manufacturing machine is not best exerted, the sand manufacturing efficiency is low and generally reaches about 280A, the work of the motor 3 reaches 90 percent at the moment, the allowance is to protect the motor 3, the instant current when large materials pass is prevented from being increased, the angle of a discharging valve (namely, a feeding turnover plate 18) is locked when the materials are gradually amplified until the working current of the motor 3 reaches about 280A, then a finished sand sample is taken to a laboratory test fineness modulus and grading, if the grading shows that the powder content is overlarge, the pressure is properly reduced to 7MPa, the throughput is increased, the working current of the motor 3 reaches the set current value of 280A, the secondary test standard is reached, and the Hall working pressure value of the hall working pressure value of the sand manufacturing machine is set to be in a normal working load state.
The working mode 2 is as follows:
when the material is not sufficiently supplied, the pressure is high, the powder content of the crushed material is increased, the angle of the feeding turnover plate 18 connected with the Hall sensor 19 is between the maximum and the minimum, a range is determined, for example, 0 degree is set when no material exists, the working mode 1 is the maximum feeding angle 35 degrees, and in the range of 5 degrees to 30 degrees, a working mode 2 is set, the pressure value is set to be 4MPa (according to the difference of the angle of the feeding turnover plate 18, a plurality of ranges are set, for example, the working mode III and the working mode IV are set, the pressure is set to be 5MPa and 6MPa, because the work mode is not full load work, the working current of the motor 3 is not 280A, in the range of 0 degree to 5 degrees, the material cannot impact on the feeding turnover plate 18, is stored in a large hopper on the sand making machine, in the range of 30 degrees to 35 degrees, the initially set working mode 1 or 2 is generally set, for the example, only, when the condition that when the material supply is insufficient, the pressure is high, the fineness and the large fineness and the hydraulic pressure of the finished product are influenced by a hydraulic pressure, the hydraulic pressure of the sand making machine is gradually increased or decreased, and the grinding process is realized along with the automatic pressure reduction and the pressure reduction of the sand making machine.
Working mode 3:
when the roller skin (usually made of wear-resistant materials such as wear-resistant pieces, high manganese alloy and the like) of the movable roller 10 and/or the fixed roller 6 is worn to the residual 40mm from 120mm, if the working mode 1 is adopted for working, along with the gradual thinning of the roller skin, the pressure is high, the risk of roller skin burst is caused, the set working mode 3 sets the pressure value to be 5MPa, the working current of the motor 3 is required to reach 280A as the pressure value is reduced, the discharging angle (namely the angle of the feeding turnover plate 18) can be properly increased, discharging is increased, but the pressure is low, the sand forming rate is lower than that of the working mode 1, the yield per unit hour can reach about 80% of the normal yield of the working mode 1 as the discharging amount is increased, only the workload of the screening equipment of a production line is increased, but the roller skin can be worn to the residual 5-10mm after the pressure reduction, the fixed loss is reduced, and the service time and the replacement period of the roller skin are prolonged. At the moment, when the system is started or shut down or the materials are insufficient, the system can be automatically switched between the working mode 2 and the working mode 3 until the roller leather is replaced by a new roller leather.
When the automatic feeding device is used, a one-key starting button is clicked on an electric appliance control cabinet 17, a system is set according to a PLC (programmable logic controller), firstly, a speed reducer thin oil station 12 and a hydraulic station 16 are started, when the speed reducer thin oil station 12 and the hydraulic station 16 normally operate, a motor 3 is automatically started to drive a speed reducer 9 to be connected with a fixed roller 6 through a power output coupler 5 to rotate, after the operation is normal, according to the program setting of the PLC, an electromagnetic directional valve controls a pressure regulating oil cylinder 14 to start automatic starting and pressurizing, a pressure regulating spring push plate 11 and a movable roller 10 connected with the pressure regulating spring push plate are pushed to move towards the fixed roller 6 together, when two roller skins are slightly contacted, the pressure is automatically pressurized to a set initial pressure (0.1-1.2 MPa), so that the fixed roller 6 can just drive the movable roller 10 to move relatively, after the two rollers of a sand making machine normally operate under the initial pressures, the PLC gives a signal, a raw material conveying device is automatically started to feed materials into a large hopper 1, materials in the large hopper 1 are pushed to rotate through a feeding turnover plate 18 to drive a rotating shaft 21 to deflect, the rotating shaft 21 installed at the end of the feeding turnover plate 21, and the rotating shaft of the feeding chute is automatically controlled by a Hall sensor, and the large chute 2 to sense the feeding chute to sense the large chute to sense the feeding mode of the large sand making machine.
When the machine is stopped, a one-key stop button on the electric appliance control cabinet 17 is clicked, and the PLC controller can reversely operate according to the starting sequence and automatically stop in sequence.
When a certain link in the production process has a problem, a worker can select an emergency stop button or a one-key stop button to operate according to the situation. And a manual mode button can be clicked to manually control the motor 3, the speed reducer thin oil station 12, the hydraulic station 16, the pressure regulating oil cylinder 14 and the electric butter machine 15.
