Description
Technical field
The present invention relates to filtering industry, especially scraper type filters.
Background technique
Scraper type filter is all that a motor drives single group scraper at present, is set among filter cylinder in scraper, scraper rotation,
Filter cylinder is fixed, and realizes cleaning blowdown process, which is to filter outward from interior, and impurity absorption causes to be difficult in cartridge interior
The case where observing impurity, also more difficult cleaning impurity；Moreover, including because of scraper, to enhancing filter cylinder intensity only outside filter cylinder
Reinforcing rib is done in portion, due to filter cylinder between filter body narrow space, in the case where not increasing filter volume, reinforcing rib
Thickness cannot be done, therefore the intensity of filter cylinder can not be increased.
Summary of the invention
The invention aims to provide a kind of high-intensitive scraper type filter for being easy to blowdown and being convenient for cleaning.
The specific technical solution of the present invention is as follows: a kind of scraper type filter, and chief component has decelerating motor, filtering
Device main body, filter cylinder, doctor blade holder, wherein decelerating motor is connected using shaft coupling with the central axis of the filter cylinder inside filter body,
Filter body inner upper is equipped with device for fixing filter cartridge, and the central axis of filter cylinder passes through centre bore and the filtering of device for fixing filter cartridge
The centre bore of device main body upper cover, filter cylinder lower section are equipped with water outlet；Filter body inner wall is equipped with doctor blade holder, scraping on doctor blade holder
Blade is close to filter cylinder outer surface, and part side-walls are equipped with water inlet on filter body, and filter body lower end is equipped with sewage draining exit.
Further, the central axis of filter cylinder is equipped with cartridge interior support ring and prevents from deforming to reinforce filter cylinder intensity.
Further, which includes an annulus and a right-angled intersection frame, the frame foot of right-angled intersection frame
4 points are fixedly connected with annulus inner ring, and annulus excircle dimension is consistent with cartridge interior sectional dimension, pass through right-angled intersection frame center
Circular hole be arranged on the central axis of filter cylinder.
Further, filter body lower end has total water outlet to be connected with the water outlet sealing below filter cylinder.
Further, central axis passes through the centre bore of filter body upper cover and is tightly connected therewith.
Further, photoscope can be set on the side wall of filter body, to observe the filter cylinder in filter body
Abrasion condition is blocked, to determine whether to stop cleaning maintenance.
After the present invention, filter is changed to from filtering inside outside, and impurity invests the outer surface of filter cylinder, is conducive to filter
The scraper of drum outer wall strikes off impurity, is easy to blowdown cleaning, and reinforcement structure can be arranged in cartridge interior, it is strong to be conducive to increase filter cylinder
Degree, by the photoscope on filter body side wall, can observe cartridge exine impurity deposition at any time, convenient for in filter
The understanding of portion's working condition, and the blocking abrasion condition of the filter cylinder in filter body can be observed, it is clear to determine whether to shut down
Wash maintenance.

Specific embodiment
A kind of scraper type filter as shown in Figure 1, chief component have decelerating motor 1, filter body 2, filter cylinder 3,
Doctor blade holder 4, wherein decelerating motor 1 is connected using shaft coupling 11 with the central axis 31 of the filter cylinder 3 inside filter body 2, is filtered
2 inner upper of device main body is equipped with device for fixing filter cartridge 32, as shown in figure 4, the central axis 31 of filter cylinder 3 passes through device for fixing filter cartridge 32
Centre bore 321 and filter body upper cover 21 centre bore 211, water outlet 33 is equipped with below filter cylinder 3；In filter body 2
Wall is equipped with doctor blade holder 4, as shown in Figure 2；Scraper blade 41 on doctor blade holder 4 is close to 3 outer surface of filter cylinder, 2 top of filter body
Side-walls are divided to be equipped with water inlet 5,2 lower end of filter body is equipped with sewage draining exit 22.
Further, the central axis 31 of filter cylinder 3 is equipped with cartridge interior support ring 34, which includes
One annulus 341 is connect with a right-angled intersection frame 342, and 4 points of frame foot of right-angled intersection frame 342 are fixed with 341 inner ring of annulus to be connected
It connects, annulus excircle dimension is consistent with cartridge interior sectional dimension, is arranged in filter cylinder 3 by the circular hole at 342 center of right-angled intersection frame
Central axis 31 on, as shown in Figure 3, Figure 4, to reinforce filter cylinder intensity, prevent from deforming.
Further, 2 lower end of filter body has total water outlet 23 and the sealing of water outlet 33 of 3 lower section of filter cylinder to be connected.
Further, central axis 31 passes through the centre bore 211 of filter body upper cover 21 and is tightly connected therewith.
Further, photoscope can be set on the side wall 24 of filter body 2, to observe the filter in filter body
Cylinder blocking abrasion condition, to determine whether to stop cleaning maintenance.
It is injected to filtrate from 2 side-walls water inlet 5 of filter body, by 3 wall of filter cylinder inside filter body 2
Hole enters inside filter cylinder 3, and residue is then attached to stay in 3 outer surface of filter cylinder, to realize the purpose of filtering, filtered filtrate then from
The discharge of 3 lower section water outlet 33 of filter cylinder is finally discharged from total water outlet 23 of 2 lower section of filter body and collects, when needing blowdown, opens
It opens decelerating motor 1 to be powered operating, decelerating motor 1 drives filter cylinder 3 to rotate together, and when rotation, is tightly attached to the scraper blade on 3 surface of filter cylinder
The residue for staying in 3 outer surface of filter cylinder attached after filtering can be scraped from the lower end sewage draining exit 22 of filter body 2 and is discharged by 41, be realized
The effect of cleaning, also filled water assists cleaning.
