Abstract
The utility model relates to an improved structure of a centrifugal acceleration disk for a push centrifuge. The centrifugal acceleration disk is installed inside a feed system of the push centrifuge and comprises a round flat plate. A plurality of vanes uniformly distributed in a curved radiation manner are arranged on one side of the round flat plate for accelerating materials, and a plurality of vanes uniformly distributed in a straight line radiation manner are arranged on the other side of the round flat plate for accelerating air to form a separation air curtain so as to apply pressure on the materials. The curve of the vanes can gradually increase the speed of the materials, ensure the synchronization of the materials and the acceleration disk, and ensure that the materials reach the highest linear velocity at a certain rotation speed when the materials move to the edge of the acceleration disk, so as to reduce the linear velocity difference between the materials and a screen mesh inside a rotating drum and reduce the impulse force to the materials.
Description
Technical field
The utility model relates to the supply system of a kind of pusher centrifuge material to be separated, relates in particular to a kind of pusher centrifuge centrifugation accelerates disk improving structure.。
Background technology
Pusher centrifuge is a kind of high efficiency filter formula centrifuge of continued operation.The suspension that needs to separate feeds centrifuge continuously through feed pipe, is quickened by feed distributor, and is sprinkling upon equably in the first order rotary drum.Solid partly is trapped within on the screen cloth and forms the ring-type filter cake, has not only done to rotate but also reciprocating first order rotary drum, when backhaul, this part filter cake is axially pushed ahead a segment distance along rotary drum, when process, on the screen cloth that filter cake is vacated, follow-up material of coming in forms new filter cake again.Reciprocating motion along with first order rotary drum, filter cake advances successively, when they when first order rotary drum enters second level rotary drum, filter cake not only position can produce and stirs, and because of having entered the rotary drum of larger diameter, so be subjected to more powerful centrifugal action, and in the two-stage rotary drum, filter cake has enough time of staying, therefore can reach very low remaining moisture percentage.When the process of first order rotary drum, the filter cake in the rotary drum of the second level continues to push ahead, outside the solid collection groove is pressed assigned direction discharge machine.Produce powerful centrifugal force because rotary drum rotates at a high speed, liquid partly is to obtain filtering through filter cake and screen cloth, and outside liquid collection trough discharge machine.When the purity to solid product has requirement, can in rotary drum, effectively wash, mother liquor and cleaning solution can also be collected respectively.
In the prior art, the feeding system of pusher centrifuge, the acceleration dish all adopts discoid shape or awl dish, and frictionally quickens material.Because various materials are different with the coefficient of friction of acceleration dish, so acceleration change is difficult to control.At the minor diameter place, because of skidding, the rotary speed of material can not improve rapidly, and to the major diameter place, the speed of material has improved, and clashes into the bolt of installing etc. again.Because it is unreasonable that acceleration distributes, and makes material when leaving the acceleration dish, speed reaches the speed at corresponding screen cloth place in the rotary drum far away, causes material to clash into once more.Crystal grain in the various like this materials also can be scratched, sanding, damaged, even broken, has reduced product quality, has strengthened operating cost.
Summary of the invention
The utility model is in order to solve the problems of the technologies described above, provide a kind of material one to enter the acceleration dish after, be forced to quicken, guarantee that simultaneously material and acceleration dish are synchronous, reduce the pusher centrifuge centrifugation accelerates disk improving structure of the impulsive force that material is subjected to.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the utility model comprises that one is circular dull and stereotyped, a described circular dull and stereotyped side is provided with the blade that several homogeneous radiations distribute, and its opposite side also is provided with the blade that several homogeneous radiations distribute.
As preferably, the described curved shape of blade of being located at a circular dull and stereotyped side.In order to quicken material.
As preferably, the described blade of being located at circular dull and stereotyped opposite side is linearly.In order to quicken air material is formed pressure.
As preferably, the described blade of being located at circular dull and stereotyped each side is 3～8.
The beneficial effects of the utility model are: make effectively the material that does not originally rotate promptly accelerate to rotary drum in the screen cloth linear velocity approaching as much as possible, enter released state, and reduce the bump that causes because of acceleration change, the wearing and tearing of the part that contacts with material can be reduced, the product serviceability rate can be improved.After air is accelerated, can increase pressure, force mother liquor to pass filter cake fast, thereby realize separating the purpose that is difficult to the material that separates in the past, can also reduce residual wet rate simultaneously filter cake surface.

The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: a kind of pusher centrifuge centrifugation accelerates disk improving structure of present embodiment, as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, centrifugation accelerates dish 1 is installed in the feeding system 2 of pusher centrifuge, it comprises one circular dull and stereotyped 3, the blade 4 that a circular dull and stereotyped side has six curved shape homogeneous radiations to distribute is in order to quicken material, the blade 5 that its opposite side has six linearly homogeneous radiations to distribute, in order to quicken air, material is formed pressure.
The centrifugation accelerates dish is installed in the coaxial position on the scraping wings in the rotary drum, with the same rotational speed of rotary drum.After material one entered the acceleration dish, under the effect of blade, material was forced to quicken, because the material of this moment is in less diametrical position, though acceleration is bigger, linear velocity is not high, and is therefore less to the impact of material yet.Curve on the blade makes material speed continue to improve, and can guarantee that material and acceleration dish are synchronous, when the edge of material movement to the acceleration dish, no matter how many coefficients of friction of material and metal is, can guarantee that also the maximum linear velocity that material reaches under this rotating speed leaves the acceleration dish, be that material is accelerated to and the immediate speed of rotary drum screen cloth, therefore realized reducing the effect of impulsive force.Because the blade curve forces material to change the direction of motion, and replaces impacting to slide, therefore, not only reduce scratch, the sanding, damaged of crystal grain in the material greatly, even broken phenomenon, and reduce the high operating cost that causes because of wearing and tearing.The blade that is the homogeneous radiation distribution of while opposite side is in order to quicken air.Filter cake surface is increased pressure, force mother liquor to pass filter cake fast, thereby realize separating the purpose that is difficult to the material that separates in the past, can also reduce residual wet rate simultaneously.
