That is, if the large ribbon blade 140 has a right screw shape, the small ribbon blade 150 is provided in a left screw shape. The reverse is also possible.

In addition, the packing shaft 160 is inserted into the center of the tank body 110 is rotated by the drive motor 120 while the packing device 160 to prevent leakage of the inside of the tank body 110 is leaking It is equipped with installation.

The packing device 160 is installed on the pivot shaft 130 inserted into the central portion of the side round portion 111a of the tank body 110, the center of the side round portion 111a of the tank body 110 In the center of the side round portion 111a of the tank body 110 by the fixing plate 161 which is installed and fixed to the flange portion 111 provided in the flange portion 111 provided by a fastening screw or the like, and the fixing plate 161. It is composed of a plate cover 162 to be fixed and supported, and a plurality of gaskets 163 installed to be inserted into the rotation shaft 130 to maintain the airtight inside the tank body 110.

In addition, a protrusion 161a having a predetermined height is formed at an outer center of the fixed plate 161.

normal P (ℓ / L) 0.08 0.16 0.24 0.32 0.4 0.4 or more

Therefore, when designing L = 25mm H = 45mm, it is most economic to set the length of the upper side (L) to 6-8 mm.

When it is expressed as P, the ratio of L and H, it can be seen that the value of P is the most economical at 0.24 to 0.32.

In addition, the weight of the raw material accommodated in the tank body 110 is 5 tons, it is operated at 11 ~ 12 RPM for 1 month, and economic length 6 ~ to minimize the length of the upper side (L) as shown in Table 1 The optimum angle of the inclination angle (θ) with 8mm (P = 0.24 ~ 0.32) is obtained experimentally.

Here, the magnitude of vibration is divided into levels as follows.

1. Vibration level at which the first vibration is felt: 55 ± 5 decibels (dB)

2. Vibration level causing damage: 60 decibels (dB)

3.The vibration level to wake up from sleep: 65 ~ 69 decibel (dB)

4.Shaking vibration level considerably: 70 ~ 80 decibel (dB)

5.Vibration level when the door of a building opens or cracks on the wall: 85 ~ 90 decibels

Therefore, the cross-sectional shapes of the large ribbon blade 140 and the small ribbon blade 150 are produced by applying the optimization conditions shown in Tables 1 and 2 as follows.

That is, when designing a trapezoidal cross section L = 25mm H = 45mm, the upper side ℓ is 6-8 mm and the inclined plane angle θ is inclined at 60 to 65 degrees.

By changing the size and shape (cross section) of the ribbon blade and deforming the packing device as described above, the vibration (vibration) is almost improved (50 decibels or less), and the gasket of the packing device has been improved in one month. In the period of exchange of 2 to 3 times, the exchange period became longer every 1 to 2 years.
