In order to achieve the purpose, the belt press type dehydrator according to the present invention includes a rotary filter cloth drive roll for driving the first and second rotary filter cloths, and a pressurizing roller. A pressure belt drive roll for driving the belt is provided in a state in which the rotary filter cloth and the pressure belt are driven separately, and each of the drive rolls is connected to a motor by a single winding transmission. In addition to being interlocked and connected, the pressure belt driving roll is wound on the pulling side of the winding transmission device by the motor and closer to the motor than the rotary filter cloth driving roll. Its action and effects are as follows.
モータの回動駆動力が１本の巻掛伝動具により
各駆動ロールに伝達されて各駆動ロールが同一速

にたるみやスリツプが生じにくいように同一速度
で回動する。
The rotational driving force of the motor is transmitted to each drive roll by one winding transmission, and each drive roll rotates at the same speed, and the rotating filter cloth and pressure belt prevent slack or slippage in the rotating filter cloth. Rotate at the same speed so that it is less likely to occur.

わるようになる。 Moreover, even if the starting force is transmitted to the driven object at the time of start-up due to slack in the wrapped transmission or stoppage of the driven object,
The starting power is first transmitted to the drive roll for the pressure belt, and the pressure belt starts rotating, and the slack in the winding transmission and the static inertia of the pressure belt are eliminated or reduced, making the power relatively quiet. The transmission structure enables the rotation of the rotary filter cloth to begin to rotate after the rotation of the filter cloth is transmitted to the filter cloth drive roll. In other words, the starting force is transmitted first to the pressure belt, which has superior strength compared to the filter cloth and is less likely to be damaged even when subjected to transmission shock, and because of this transmission, the power is transmitted quietly, and the power is Even if transmission occurs, power is transmitted to the filter cloth only after abnormal tension is less likely to occur.

Therefore, no sagging or slipping occurs in the rotating filter cloth, and good dewatering performance can be achieved due to the strong pressure applied by the pressure belt, and damage to the filter cloth can be avoided due to the reasonable tension. Overall, we were able to maintain high dehydration performance over a long period of time.
