Abstract
The present invention discloses one kind of filter unit set inside the centrifuge drum and with high filtering capacity and high filtering efficiency. The filter unit includes one pushing disc inside the drum, and filter strips around the pushing disc and with some interval in between. All the filter strips are arranged on the inner wall in one circle. There are filtrate holes in the filter strips and corresponding liquid passing holes in the pushing disc communicated to the liquid exhausting holes in the drum. The present invention is applied mainly in horizontal inner filtering centrifuge.
Description
Technical field
The present invention relates to bowl, refer more particularly to the filter in the bowl.
Background technology
At present, the filter that is provided with in the bowl all is traditional screen pack, and its structure all is the cylindrical shape that the shape with rotary drum adapts usually, that is: whole screen pack is done as a wholely to form a circle along drum inner wall.In the course of work of centrifuge, the suspension that enters centrifuge is thrown to the filtering surface of filter screen---and both contacts area reach maximum, the filter cake that the dehydration back forms is easy to the mesh of screen pack is blocked, along with filter cake at screen pack surface progressive additive, filtration resistance increases gradually, and filtering rate significantly reduces, for thin sticking or the compressibility filter cake is particularly evident, otherwise how long, centrifuge is normal dewatering and filtering just; At this moment, centrifuge can only be closed down, filter cake is drawn off, and remove filter screen, and then filter next time.Like this, once the amount of Guo Lving very little, a lot of times are all spent in the discharging, have influenced filter efficiency greatly.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of and increase each filtration yield, improve the filter in the bowl of filter efficiency.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the filter in the bowl, comprise: be arranged on the pusher dish in the rotary drum, the periphery of pusher dish is provided with the strip filter leaf of several independent, be provided with the space between the adjacent filter leaf, all these filter leafs become a circle along drum inner wall circumference cloth, each filter leaf is being provided with filtrate hole near the place, bottom of the drum, the pusher dish is provided with and the corresponding liquid pass hole of each filtrate hole, and all liquid pass holes communicate with outage in the rotary drum.
Above-mentioned strip filter leaf is parallel to each other, is evenly distributed on the periphery of pusher dish.
The invention has the beneficial effects as follows: because the pusher dish in the rotary drum is provided with the strip filter leaf of several independent, avoided suspension to contact with the front of strainer filtering face, thereby both contact-making surfaces have been reduced, and also be provided with the space that is used to settle filter cake between the adjacent filter leaf, prevented the mesh obstruction of filter cake effectively with filter screen, make the filtration yield that at every turn enters in the rotary drum be greatly enhanced, thereby improved filter efficiency.

The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As Fig. 1, shown in Figure 5, filter in the bowl of the present invention, comprise: be arranged on the pusher dish 3 in the rotary drum 1, the periphery of pusher dish 3 by plug 24 be provided with eight separate, the strip filter leaf 2 that is axial arranging, as shown in Figure 3, each filter leaf 2 comprises: two support plates 21, two blocks of side plates 22 and two filter screens 23, form the strip tetragonal body of a hollow structure, be respectively arranged with the plug via hole 211 that is used to wear plug 24 on two support plates 21, be provided with the space that is used to settle filter cake between two adjacent filter leafs 2, all these filter leafs 2 are parallel to each other, and become a circle along the even cloth of rotary drum 2 inwall circumference---referring to shown in Figure 2, each filter leaf 2 is provided with filtrate hole 221 near in the side plate 22 of rotary drum 1 bottom, pusher dish 3 be provided with eight respectively with eight blocks of side plates 22 on eight filtrate hole, 221 corresponding liquid pass holes 30---referring to shown in Figure 4, these eight liquid pass holes 30 all are connected with outage 10 in the rotary drum 1.In the present embodiment, also be provided with between the lip ring 4 and lip ring 4 and filter leaf 2 that is used for capping rotary drum 1 on the described plug 24, the cushion block 25 between the bottom of filter leaf 2 and rotary drum 1---referring to shown in Figure 5; The bottom of pusher dish 3 and rotary drum 1 also is provided with the spout hole 7 that suspension mutual perforation, that be used for preventing rotary drum 1 too much influences filter effect.
The course of work of this filter is: the suspension of coming in from feed tube 6 enters into rotary drum 1 after acceleration bucket 5 quickens, enter suspension in the rotary drum 1 and under action of centrifugal force, get rid of inwall to filter leaf 2 and rotary drum 1, like this, filter cake just is deposited in the space of adjacent filter leaf 2, filtrate then outwards throws away from filtrate hole 221, and the filtrate that throws away discharges through the liquid pass hole 30 in the pusher dish 3 and the outage 10 of rotary drum 1 bottom.
Because the pusher dish 3 in the rotary drum 1 is provided with the strip filter leaf 2 of several independent, avoided suspension to contact with the front of filter screen 23 filtering surfaces, thereby both contact-making surfaces have been reduced, and also be provided with the space that is used to settle filter cake between the adjacent filter leaf 2, prevented the mesh obstruction of filter cake effectively with filter screen 23, make the filtration yield that at every turn enters in the rotary drum 1 be greatly enhanced, thereby improved filter efficiency.
Claims (2)
1. the filter in the bowl, comprise: be arranged on the pusher dish in the rotary drum, it is characterized in that: the periphery of pusher dish is provided with the strip filter leaf of several independent, be provided with the space between the adjacent filter leaf, all these filter leafs become a circle along drum inner wall circumference cloth, each filter leaf is being provided with filtrate hole near bottom of the drum place, and the pusher dish is provided with and the corresponding liquid pass hole of each filtrate hole, and all liquid pass holes communicate with outage in the rotary drum.
