The inner wall of the filter cartridge 5 above the sliding opening 12 is provided with internal threads, and the outer arc walls of the multiple groups of arc-shaped plates 16 at the top are provided with external threads which are in threaded connection with the internal threads.
As shown in fig. 1, the screw 11 extending to the lower part of the filter cartridge 5 is used to support and fix the filter cartridge 5 so as to suspend it, and the support rod 8 pulls the filter cartridge 5 downwards through the ring 6 to prevent it from moving upwards, thereby indirectly achieving the problem of suspending and fixing the filter cartridge 5 in the tub 1 so as to prevent it from moving up and down or horizontally, wherein when the cover plate 2 is placed at the top of the tub 1, it will drive the arc plates 16 and the fixing rings 15 to insert into the filter cartridge 5, at this time, the rotating cover plate 2 drives the external threads on the arc plate 16 at the top to be screwed with the internal threads on the top of the filter cartridge 5, thereby preventing the arc plates 16 and the fixing rings 15 from sliding out from the filter cartridge 5 without human intervention, meanwhile, the upper and lower sets of arc plates 16 on the same side can seal the corresponding sliding openings 12, thereby preventing the problem that the liquid will flow out through the sliding openings 12 after being introduced into the filter cartridge 5, wherein the rotating rod 21 can also rotate to make the external threads on the top of the outer side wall screwed with the coil II pocket 23, thereby making the filter cartridge 17 fixed by the connecting rod 18 and the clamping block 28, so as to prevent the filter pocket from being influenced by the external force.
So when using in the thick liquids through feed inlet 3 cartridge filter 5, the thick liquids filters through the filter screen pocket II17 of the different apertures of upper and lower multiunit this moment, filter the large granule that exists in the magma, still carry out final filtration to it through filter screen pocket I7 and 5 lateral walls apertures of cartridge filter 5 after then, the pulpiness can follow discharging pipe 3 play after filtering, at above-mentioned in-process when thick liquids are filtering through upper and lower multiunit filter screen pocket II17 and 5 diapire apertures of cartridge filter, still accessible cartridge filter 5 on the lateral wall aperture of aperture to standard thick liquids simultaneously, with this promotion filtration efficiency, and the large granule that filters down can receive the action of gravity to fall filter screen pocket I7, on the filter screen pocket II17 and the adhesion on 5 inner walls of cartridge filter.
When the slurry filtered from the side wall aperture of the filter cartridge 5 falls down in the above process, the protective cylinder 25 can shield the slurry, so as to prevent the slurry from contacting the joint between the upper barrel 101 and the lower barrel 102, thereby preventing the slurry from overflowing from the gap between the upper barrel and the lower barrel.
When the filtering net bag I7, the filtering net bag II17 and the filtering materials or the adhesive materials on the filtering cylinder 5 need to be cleaned after the filtering is finished, only the cover plate 2 needs to be separated from the barrel body 1, and then the arc-shaped plate 16 and the fixing ring 15 need to be taken out from the filtering cylinder 5, at the moment, if the filtering net bag II17 needs to be cleaned, only the rotating rod 21 needs to be rotated upwards to separate the external thread on the outer wall of the top of the filtering net bag from the solenoid II23, meanwhile, the rotating rod 21 can rotate in the rolling bearing 20 to prevent the rotating rod from driving the filtering net bag II17 to rotate together through the connecting rod 18, and further the problem that the filtering net bag II17 is twisted and pulled to be broken is solved, after the external thread on the rotating rod 21 is separated from the solenoid II23, the rotating rod 21 can be pulled to reciprocate up and down in the solenoid II23, the rotating rod 21 drives the side wall of the filter net bag II17 to deform through the rolling bearing 20, the fixing seat 19, the connecting rod 18 and the clamping block 28 so as to enable the side wall of the filter net bag II17 to be sunken downwards or to be protruded upwards, large particle materials adhered to the side wall of the filter net bag II17 after drying are separated from the side wall of the filter net bag II17, and then the cleaning is facilitated, meanwhile, the connecting rod 18 can be rotated to drive the clamping block 28 and the protrusion embedded into the pore diameter of the side wall of the filter net bag II17 to rotate, so that the side wall of the filter net bag II17 is twisted clockwise and anticlockwise, large particle materials adhered to the side wall of the filter net bag II17 after drying are separated from the side wall of the filter net bag II17, and then the cleaning is facilitated, and the middle of the filter net bag II17 sags, so that the deformation range of the filter net bag can be enlarged while the filter area is enlarged, and the problem that the filter net bag is easy to break or tear when the filter bag is driven to deform under the tight state is prevented.
As shown in fig. 2, when the filter cartridge 5 needs to be cleaned, the cylinder 24 can be separated from the lower cylinder 102, and further the upper cylinder 101 and the protective cylinder 25 can be separated from the lower cylinder 102, so that the screw 11 can be rotated outwards to move the end of the screw out of the bottom of the filter cartridge 5, and under the influence of gravity, the filter cartridge 5 will drive the sliding opening 12 to move downwards on the sliding block 13, so that the ring 6 and the inclined plane 27 at the top of the side wall of the receiving groove 14 can scrape off the adhered substance on the inner and outer side walls of the filter cartridge 5 moving downwards gradually, so that the adhered substance falls into the filter net bag I7 or the receiving groove 14, and can be forced to move downwards in a manual intervention manner when the filter cartridge 5 is slowed down after being subjected to resistance.
In the process, as the bearing groove 14 and the filter net bag I7 are close to the top opening of the filter cartridge 5 or the top opening of the lower barrel 102, people can easily clean large-particle materials collected on the bearing groove 14 and the filter net bag I7, so that the purpose of cleaning adhered materials on the inner side wall and the outer side wall of the filter cartridge 5 is achieved.
The bottom of the inner side wall of the circular ring 6 is provided with a circle of flexible support ring 26 used for supporting the edge of the side wall of the filter net bag I7, wherein the section of the support ring 26 is in a right triangle shape, and a same horizontal plane is arranged between one right-angle side of the support ring 26 and the bottom end of the circular ring 6.
The middle of the bottom wall of the filter cartridge 5 is recessed downwards to form a recessed part 29, wherein a filling block 30 matched with the recessed part 29 in size is arranged in the recessed part 29, a finger groove is formed in the top end face of the filling block 30, a rotating shaft penetrating through the side wall of the recessed part 29 is arranged at the bottom of the filling block 30, a scraping rod 31 tightly attached to the bottom end face of the bottom wall of the filter cartridge 5 is arranged on the rotating shaft, and the scraping rod 31 is located in a circular opening formed among the support rods 8.
When the bottom end face of the bottom wall of the filter cartridge 5 needs to be cleaned, if the filter net bag I7 is detached, the bottom of the filter cartridge 5 can be cleaned by rotating the filling block 30 and driving the scraping rod 31 through the rotating shaft, and meanwhile, the bottom end face of the filter cartridge 5 can be cleaned by directly rotating the scraping rod 31 at the bottom of the filter cartridge 5, so that the aim of conveniently cleaning the side wall and the bottom wall of the filter cartridge 5 and the filter net bag II17 is fulfilled finally.
The present invention has been described in detail, but the above description is only a preferred embodiment of the present invention, and is not to be construed as limiting the scope of the present invention.
