Rotating shaft, the self-locking nut for preventing axial float is fitted with the termination of rotating shaft.
Specifically used process of the present utility model is as follows：
（One）Compaction process
First, installation site of the circular filter on cleaning equipment main body frame is determined, is set in purification
The installation site on sealing panel in standby cavity, in the periphery of circular filter, along the diametric extension of circular filter
On line and according to the spacing of the U-shaped open trough in the both ends of compressor arm 2, two tie-struts 5 are passed through into welding or the method for screw threads for fastening
It is fixed on suitable position on sealing panel；Then, spacing handle 3 and tie-strut 5 are carried out by pre-assembled by fixture block 7；With
Afterwards, the U-shaped horizontal connection groove 1-1 that pressing handle 4, compressor arm 2 and three-pawl type are compressed to pallet 1 is embedded in successively from inside to outside, and
Eccentric wheel 4-2 in pressing handle 4, spanner handle 4-1, the pin hole of the center position of compressor arm 2 and three-pawl type are compressed and held in the palm
Key groove shape in disk 1 on U-shaped horizontal connection groove 1-1 hole site of having strong market potential aligns, and installs bearing pin or screwed rotating shaft and is equipped with
Corresponding split pin or nut, i.e., now pressing handle 4, compressor arm 2 and three-pawl type compress the three's pre-assembled of pallet 1 as one
It is overall；And then, circular filter is placed on to the sealing panel surface of cleaning equipment, by above-mentioned and pressing handle 4, compressor arm
The three-pawl type compression pallet 1 that 2 prepackages are made into an entirety is pressed on circular filter top surface, i.e. the bottom surface of supporting leg and circle
Filter top surface contacts；Then, spacing handle 3 is passed through out of U-shaped open trough of the both ends of compressor arm 2 and hangs the horizontal handle in top
Hang in the gap that the side wall of compressor arm 2 opens up；Followed by, pulling the rotation of pressing handle 4 makes eccentric wheel 4-2 be in impaction state,
Clamping plane of the distalmost end along projection string of a musical instrument processing on eccentric wheel 4-2 apart from pin hole center is allowed to compress pallet with three-pawl type
1 U-shaped horizontal connection groove 1-1 bottom land plane contact；Check and measure whether the size after circular filter compresses meets to press
The requirement of contracting amount：If being unsatisfactory for decrement requirement, the upper and lower tables of ring-type connecting plate 5-1 positioned at the top of tie-strut 5 are readjusted
The nut in face, untill decrement requirement is met.
（Two）Unloading process
Demolishing process is reverse operating：First, pulling the rotation of pressing handle 4 makes eccentric wheel 4-2 be in releasing orientation, that is, allows
On eccentric wheel 4-2 apart from pin hole center most proximal end close to U-shaped horizontal connection groove 1-1 bottom land plane then；Then, will limit
The horizontal handle in top of position handle 3 departs from out of compressor arm 2 side wall gap, outwards rotation, out of, U-shaped open trough of the termination of compressor arm 2
Middle back-out；Then, three-pawl type assembling being integrated compresses pallet 1, compressor arm 2 and pressing handle 4 and taken away；Finally, circle is pulled out
Shape filter just completes the dismounting work of circular filter.
