JPH10277316A - Agitation transmission device for filter medium in filter - Google Patents

Abstract

PROBLEM TO BE SOLVED: To easily adjust an axial distance between a drive axis and a motor axis in an arrangement wherein an agitation impeller for filter medium provided at the bottom of a filter tank is driven by a motor by urging a mount base for a motor provided under a filter tank through a coil spring so as to be spaced apart from the drive axis. SOLUTION: In a mount base 6 for mounting a motor 5 for driving an agitation impeller 4, one end thereof is swingably mounted to a leg 7 of a filter tank and an adjusting screw 10 erected on a supporting rod 9 suspended from the underside of the filter tank is inserted into the other end of the base 6. And a coil spring 11 and an adjusting nut 13 are fitted on the screw 10 to urge the base 6 in a direction opposite to a drive axis 12. Since the base 6 is urged by the spring 11 so as to be spaced apart from the axis 12, a belt 17 stretched between a drive pulley 14 and prime pulley 15 is tightly stretched so that the power of the motor 5 can be efficiently transmitted to the impeller 4 and the degree of tension of the belt can be desirably adjusted by means of the nut 13.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in an agitation transmission device for washing a filter medium of a filter using a floating filter medium. It is an object of the present invention to provide a device capable of efficiently stirring a filter medium in a filtered filter.

[0002]

2. Description of the Related Art Conventionally, a filter medium stirring device of a filter using a floating filter medium is well known. Japanese Utility Model Application No. 1-88330 is an example. In this invention, the drive motor of the stirring blade installed below the filter tank can be moved toward and away from the stirring shaft so that the tension of the belt stretched between the pulley of the stirring shaft and the drive pulley of the motor can be adjusted. I have to.

[0003]

However, in the conventional apparatus, it is difficult to replace the belt or adjust the slack belt because the belt is located in a narrow place below the filtration tank. Even if the center distance can be adjusted as in the above-mentioned Japanese Patent Application No. 1-88330, the adjustment operation is difficult.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and is intended to easily and easily adjust the distance between the driving shaft of the motor and the driving shaft of the stirring blade. The belt can be easily tensioned and maintained, and a belt tensioning device is provided between the driving shaft and the drive shaft so that transmission can be performed with the highest efficiency.

That is, the gist of the present invention resides in a filter using a floating filter medium in which a stirring blade of a filter medium provided at the bottom of the filter tank is driven by a motor provided below the filter tank. The drive shaft of the stirring blade penetrates through the bottom of the filter tank, and a motor mount is provided below the filter tank so as to be able to approach and separate from the suspended drive shaft, and the motor mounted on this mount A belt is hung between the driving pulley of the motor shaft and the driving pulley of the driving shaft, and the mounting base is urged away from the driving shaft via a coil spring.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The apparatus according to the present invention is configured as described above, and the drive motor can be freely approached to and separated from the drive shaft of the stirring blade via a coil spring. Adjust the distance between the motor shafts,
The belt suspended between these shafts is tensioned to efficiently transmit power to the stirring blade, and the drive motor can be taken out from below the narrow filtration tank to facilitate maintenance such as belt replacement. It was done. The present invention will be specifically described based on the drawings.

FIG. 1 is a schematic side view of a filtration apparatus according to the present invention. Reference numeral 1 denotes a filtration tank, 2 denotes a floating filter medium, 3 denotes a water collecting nozzle, and 4 denotes a filter medium when clogged. Stirring blades 5 for stirring are motors for driving the stirring blades 4.

Next, a transmission mechanism between the motor 5 and the stirring blade 4 will be described with reference to FIGS. The motor 5 is mounted on a mounting base 6 as shown in FIG. 2, and one end of the mounting base 6 is hinged to a leg 7 of the filtration tank 1 by a hinge 8, and at the other end, , Filtration tank 1
An adjustment screw 10 implanted in a support rod 9 hanging down from the lower surface of is inserted. A coil spring 11 and an adjusting nut 13 are fitted into the adjusting screw 10, and the mounting base 6 is urged to move away from the drive shaft 12. Sign 1
Reference numeral 4 denotes a driving pulley of the stirring blade 4, reference numeral 15 denotes a driving pulley provided on a motor shaft 16, and reference numeral 17 denotes a belt.

As is apparent from the above description, in the apparatus according to the present invention, the mounting base 6 is urged by the coil spring 11 so as to be separated from the drive shaft 12, and is provided between the drive pulley 14 and the driving pulley 15. The hung belt 17 is taut, and the motor 5
Power can be transmitted efficiently.

In a conventional filter in which the driving motor 5 is provided below the filter tank 1, it is difficult to provide a tension device for the belt 17 because the area below the filter tank 1 is narrow, and the belt 17 may be stretched. However, according to the present invention, the belt 17 is constantly tensioned to enable efficient power transmission, and the degree of the tension is adjusted by the adjustment screw provided on the adjustment screw 10. The nut 13 allows easy adjustment to the desired degree of tension.

Further, the apparatus according to the present invention has a mounting base 6 on which a motor 5 is mounted as shown in FIG. This is convenient for the maintenance of the belt 17.

[0012]

As described above, the stirring transmission according to the present invention can transmit power to the stirring blade more efficiently while being installed in a narrow place as compared with a conventional device of this type. This greatly facilitates assembly and maintenance of the transmission.
