According to the fact that a sugar refinery is put into production and use in recent years in squeezing seasons, the overall operation basically meets production through early test operation and improvement, and the method comprises the following steps:

1. each soil removing roller stably runs, and the running current of a motor (the rated current of the motor is 28.8A) is generally as follows: 2# soil removing roller: 10-14A; no. 3 soil removing roller: 12 to 18A. The currents of the soil removing rollers of the No. 3 soil removing machine group 3 and the No. 6 soil removing machine group 6 are respectively about 15.5A and 18A, and the rest is 12A.

2. The 2# and 3# systems have the advantages that the operation is normal in the production of the soil removing roller in the squeezing season, the bearing has no abnormal sound and generates heat, the fault rate is low, the soil removing roller teeth have no mud clamping trip phenomenon, and the high-pressure water gun is not needed to wash the teeth of the soil removing roller teeth. In the season of squeezing out the juice, need wash with high-pressure squirt about the cubic about every class and clear away wheel tooth and press from both sides silt particle, just can guarantee to remove the native roller and not cross the flow, guarantee the continuous operation of production, and often appear removing accidents such as native roller cycloid pin gear speed reducer bearing, cycloid wheel damage, motor short circuit. At present, because the power of an old motor is low (15W, and other plants are 30 KW), when a secondary belt stops, a primary belt runs and brings a large bundle of sugarcane to stay at a tail end soil removing roller, the soil removing roller of the 2# system occasionally has an overcurrent tripping phenomenon, and the normal operation is recovered after the 2# system is restarted, so that the tripping phenomenon can be avoided in operation attention. The fault pairs of the front/rear soil removing machines adopting the system are as follows:

TABLE 1 Fault comparison table for fore/aft squeezing season soil removing machine adopting the system

From the table, it can be seen that the 19/20 squeezing seasons adopting the system have five soil removal machine stops, and the reasons are that iron ware and small stones brought by sugarcane are clamped into the soil removal roller, so that overcurrent tripping is caused, and equipment faults do not occur. Compared with a season soil removing machine without the system, the system has greatly improved fault frequency, and ensures that the season production is carried out safely and uniformly.

3. The sugarcane leaking amount of the soil removing roller is greatly reduced compared with that of the prior year, the effects of removing silt and sugarcane leaves are good, according to the statistics of 19/20 squeezing seasons, the average weight of factory waste every day is 23.07 tons, and the weight is reduced by 3.21 tons in the same period compared with that of the last squeezing season, and the detailed table is shown in the following table 2:

TABLE 2 comparison statistical table for the outgoing weight of the waste of the soil removing roller

After the 2# and 3# sugarcane self-discharging systems are transformed according to statistics (hereinafter referred to as 2# and 3# soil removing machines), the fault rate of the 2# and 3# soil removing machines is greatly reduced, the operating safety rate in season is 100%, the sugarcane falling is greatly ensured to be continuously balanced, the average extraction rate of first-line and second-line pressing is promoted to be stably improved, and the economic benefit is converted as follows:

1. the loss time of the fault of the soil removing roller of the No. 2 and No. 3 soil removing machines in the season of not adopting the system is about 69 hours, and the loss is about 0.2 ten thousand yuan in each hour, so that the economic loss caused by shutdown can be reduced: 69 hours × 0.2 ten thousand yuan/hour =13.8 ten thousand yuan.

2. The cost for maintaining the speed reducer and the motor and replacing the bearing in the top squeezing season is 5.6 ten thousand yuan.

3. Because the soil removing gear piece of the soil removing roller deforms and falls off, the cost for normal use is about 100 ten thousand yuan only by maintenance in the maintenance period.

4. Adopt this system to remove native machine and reform transform the back, it is effectual to remove mud, and the mud volume that removes totally of 19/20 1 ~ 3# sugarcane self-discharging system of season is 2225.3 tons, according to two thirds volume, and 2#, 3# remove native machine and remove mud volume and be about 1483.5 tons after reforming transform, have more scientific knot miscellaneous data for the agricultural affairs branch of academic or vocational study, according to 500 yuan/ton of sugarcane purchase price, the prediction reduces the sugarcane and contains miscellaneous expense and be: 2225.3 ton x 0.05 ten thousand yuan/ton cane =111.265 ten thousand yuan.

The total cost of the four expenses is saved by 230.7 ten thousand yuan, and the economic benefit is obvious.
