Abstract

The utility model discloses a self-cleaning screening machine which comprises a feed part, a rack, a discharge part, a transmission part, a screen body and a cleaner, wherein the screen body is arranged on the rack; the feed part is arranged at the upper part of the screen body; the discharge part is arranged at the bottom of the screen body; the transmission part is connected with the screen body; and the cleaner is plugged into a screen cut. The self-cleaning screening machine disclosed by the utility model has a simple structure; and particularly, by adopting the cleaner, the machine can clear the coal blocking screen meshes anytime so as to realize an effect of automatically cleaning the blocked screen cut instead of manual cleaning after shutdown, thereby improving the working efficiency and reducing the labor intensity.

Description

The self-cleaning type screening machine

Technical field

The utility model relates to a kind of machinery of screening coal of large-scale aluminium manufacturer, particularly relates to a kind of self-cleaning type screening machine.

Background technology

At present, each big aluminium manufacturer in the screening process of coal, the general two-spool equipment of screening coal that adopts.The screen coal mode of action of equipment of birotor is: bi-motor drives two rotor rotation, and the bamboo rake in the middle of the big driven by motor rotates the extruding coal, and the sieve aperture of the coal rotor from the outer ring that meets the trimmed size size is spilt, and plays a sieving actoion.Because this equipment is birotor, thus need two motor-driven, two decelerators, the structure more complicated, equipment failure rate is high, and cost is also just high.Because the humidity ratio of coal is bigger, relatively stickingly be easy to be bonded on the sieve aperture, can block sieve aperture for a long time, need the labor cleaning, the wasting manpower and material resources.

Therefore, how a kind of, real one of the current important research and development problem that belongs to, also becoming the current industry utmost point needs improved target.

Summary of the invention

The purpose of the utility model is, a kind of self-cleaning type screening machine is provided, and makes it simple in structure, and fault rate is low, and cost is low, and equipment can oneself be cleared up the coal that blocks sieve aperture, has reduced workman's workload.

The purpose of the utility model and to solve its technical problem be that technical scheme below adopting realizes.A kind of self-cleaning type screening machine according to the utility model proposes comprises: feeder, frame, discharging portion, a driving section, a sieve nest, a sweeper.Wherein said sieve nest is contained on the frame, and this feeder is fixed on the top at this sieve nest, and this discharging portion is fixed on the bottom of this sieve nest, and this driving section and sieve nest connect, and this sweeper is contained in and is fixed on the frame, and the sieve sheet in the sweeper is filled in the sieve seam of sieve nest.

The purpose of the utility model and solve its technical problem and can also adopt following technical measures to come further to realize.

The aforesaid sieve seam of the sieve nest that lathe fine finishining forms that uses is long strip type.

Aforesaid self-cleaning type screening machine, wherein said sieve nest and sweeper adopt high abrasion resisting material.

The utility model compared with prior art has tangible advantage and beneficial effect.By technique scheme, the utility model self-cleaning type screening machine has advantage and beneficial effect at least:

1, the utility model has reduced by 1 rotor with respect to the birotor equipment of screening coal, 1 drive motors, and 1 decelerator is so the utility model is simple in structure.Because equipment is few, fault rate is low, and cost is low.

2, the sweeper in the utility model is fixed on the frame, and the sieve sheet in the sweeper is filled in the sieve seam of sieve nest, and sieve nest rotates with motor; The sieve sheet is motionless, and along with the rotation of sieve nest, the sieve sheet is cleared up away the coal that is mingled with in the sieve seam; Cleaning blocks the coal of sieve aperture to make it reach at any time, thereby reaches the effect of the sieve seam of automatic cleaning obstruction, does not need to shut down the labor cleaning to sieve seam again; Improve operating efficiency, reduced labour intensity.

Above-mentioned explanation only is the general introduction of the utility model technical scheme; In order more to know the technological means of understanding the utility model; And can implement according to the content of specification, and for let the above-mentioned of the utility model with other purposes, feature and advantage can be more obviously understandable, below special act preferred embodiment; And conjunction with figs., specify as follows.

The specific embodiment

For further setting forth the utility model is to reach technological means and the effect that predetermined goal of the invention is taked; Below in conjunction with accompanying drawing and preferred embodiment; To its specific embodiment of self-cleaning type screening machine, structure, characteristic and the effect thereof that proposes according to the utility model, specify as after.

Shown in Figure 3 like Fig. 1 Fig. 2, a kind of self-cleaning type screening machine comprises feeder 1, frame 2, discharging portion 3, driving section 4, sieve nest 5, a sweeper 6.Wherein this sieve nest 5 is contained on the frame 1, and this feeder 1 is arranged on the top of sieve nest 5, and this discharging portion 3 is arranged on the bottom of sieve nest 5, and this driving section 4 connects with sieve nest 5.Driving section 4 in the present embodiment is made up of decelerator of a motor.These sweeper 6 plugs do not contact with the sieve seam in the middle of the sieve seam.Said sieve nest 5 adopts high abrasion resisting material with sweeper 6.The sieve seam of said sieve nest 5 forms with lathe fine finishining, has guaranteed uniform sieve back granularity.As shown in Figure 3, the sieve seam of this sieve nest is long strip type.This sieve nest and sweeper adopt high abrasion resisting material.

Coal gets in the sieve nest 5 from feeder 1; This motor drives sieve nest 5 through shaft joint and a decelerator and rotates; This sieve nest 5 drives coal and rotates, and the coal that in rotation process, reaches the requirement granularity spills from the sieve seam of sieve nest 5, and coal is being driven by sieve nest and rotating; The last coal of discharging portion that gets into sieve nest lower floor spills from the sieve seam of sieve nest, and the coal that does not reach granularity requirements spills above sieve nest.When sieve nest 5 rotates, can regulate the sweeper 6 that is fixed on the frame 2, this sieve nest 5 rotates at every turn, and sweeper 6 all is stained with sticking coal in the cleaning sieve seam automatically.The sieve seam just can not blocked by coal like this.

The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Though the utility model discloses as above with preferred embodiment, yet be not that any professional and technical personnel of being familiar with is not in breaking away from the utility model technical scheme scope in order to qualification the utility model; When the technology contents of above-mentioned announcement capable of using is made a little change or is modified to the equivalent embodiment of equivalent variations; In every case be the content that does not break away from the utility model technical scheme, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of the utility model technical scheme according to the technical spirit of the utility model.
