Description

[Detailed description of the invention] The present invention provides first and second
The present invention relates to a drive structure for a dewatering device in which a plurality of belt press type dehydrators each having an endless belt filter cloth rotatably installed are arranged in parallel.

The above-mentioned dewatering equipment is designed to be able to easily respond to large changes in the amount of material to be processed due to seasonal changes, such as summer and winter, by changing the number of dehydrators that are operated. Conventionally, in order to drive these dehydrators, a separate drive mechanism such as an electric motor was provided for each, which increased the initial cost.

In view of the above points, the present invention aims to simplify the drive structure and reduce the initial cost.

Next, embodiments of the present invention will be described in detail based on illustrative drawings.

A pump 2 is installed in a storage tank 1 that supplies and stores materials to be treated such as sludge.
A processing material supply device 3 formed by connecting a pipe line R1 with a
, and a flocculant mixing device 6 is provided in which the flocculant storage tank 4 is connected to a pipe line R2 in which a variable capacity pump 5 is interposed,
After supplying the processed material and flocculant from both devices 3 and 6 to the rotary mixer 7 attached to each, and coagulating and mixing them,
It is configured to supply the water to belt press type dehydrators 8, 8 which are arranged in two stages in the vertical direction, and can be incorporated into various water treatment systems such as human waste, urban sewage or industrial wastewater.
A dewatering device is installed to dewater the materials to be treated, such as sludge, generated therein.

Each of the belt press type dehydrators 8, 8 is provided with an endless belt-shaped first rotary filter cloth 9, and a material to be mixed is mixed between the first filter cloth 9 and the case side wall and the partition wall 10 as a feeder for the material to be treated. machine 7
A gravity dewatering section 11 is formed in which the material to be processed is supplied and the water is filtered by gravity. A cake thickness adjustment roll 12 is provided as an example of an adjustment device for adjusting the thickness of the cake, and a second roll is provided on the lower side of the roll to pinch the cake whose thickness has been adjusted between it and the first rotary filter cloth 9. A moving filter cloth 13 is provided to form a forced dehydration section 14 consisting of a light pressure dehydration zone A having a linear path, a compression dehydration zone B having a large diameter arcuate path, and a shear dehydration zone C having a meandering path;
A dehydrated cake takeout part 15 is formed on the lower side thereof, and the dehydrated cake takeout part 15 is formed from the processed material supply part 11 of the first filter cloth 9.
It is designed to dehydrate the object as it rotates.

To drive the dehydrators 8, 8, driving rolls 16a for the respective first and second rotary filter cloths 9, 13.9, 13.
, 16b, 16c, and 16d are provided at the side of the cake removal section 15, and a rotating shaft 17 is attached to each of the rolls 16a so as to be freely rotatable as a unit.
7... A sprocket 18 is attached to each of them so as to be freely rotatable, and a single chain 21 is wound around these sprockets 18... and a drive sprocket 20 mounted on the output shaft 19 of the electric motor M. It is.

The sprockets 18 are attached to each of the rotating shafts 17 via sliding bearings 22 so as to be relatively rotatable, and are integrally rotatable by being fitted with a key to each of the rotating shafts 17. Attach the flange-shaped mounting member 23, attach the connecting bolt 24 to the mounting member 23, and form a threaded portion 25 for screwing the bolt 24 onto the sprocket 18. By connecting or disconnecting the mounting members 23..., all of the drive rolls 16a... are driven by the motor M, and the upper two drive rolls 16a, 16b are driven. A state in which only the upper dehydrator 8 is driven or two lower driving rolls 16C9
16d and only the lower dehydrator 8 is driven.

The bolts 24... have a set strength, so that the bolts 24... will break when the rotational drive load of each of the filter cloths 9, 13, 9, 13 exceeds the set value. It also has the function of a share pin.

To drive the chain 21, various configurations such as not only the electric motor M but also a hydraulic motor can be employed, and these are collectively referred to as a drive mechanism M.

The present invention can be applied to a type in which three or more dehydrators 8 are provided, or the dehydrators 8 may be arranged in parallel in the horizontal direction.

In summary, the present invention provides the dehydration device described above.
A sprocket 18 is attached via a slide bearing 22 to each rotating shaft 17 to which the drive roll 16a of the first and second filter cloths 9, 13, . , the mounting member 23 is attached so as to be integrally rotatable, and one drive mechanism M is attached to all of the sprockets 18.
In order to wind one chain 21 that is driven and rotated by the sprocket 18 and the mounting member 23, the sprocket 18 and the mounting member 23 can be rotated integrally to connect or disconnect them from the drive mechanism M. A feature is that the bolt 24 connected to the main body is provided so that the connection can be freely operated.

In other words, since a plurality of dehydrators 8 are driven by one drive mechanism M and one chain 21, it is not necessary to install many stages of drive mechanisms such as motors, and the initial cost can be reduced. Ta.

Moreover, in order to change the number of dehydrators 8 to be driven, the mounting member 23 and the sprocket 18 are connected or disconnected via the bolts 24, which reduces the structural cost compared to, for example, a case where a clutch mechanism is provided. This makes it possible to easily reduce initial costs.
