Abstract

The utility model discloses a jigging conveyer for granular material, such as coal, comprising a hopper and a vibrator driving the hopper vibrating. The jigging conveyer is characterized in that a dewatering structure is arranged on the jigging conveyer, and a dewatering device is not required to arrange again; the dewatering structure is not easy to be blocked, so that the fine material mixed in the water can be recycled, and can not be vented to pollute the environment.

Description

Jigging conveyer for granular material

The utility model is a kind of device of carrying loose grain piece material, and it comprises feed hopper and drives the vibrator of feed hopper vibration.

In the actual production, material often is moisture, needs dehydration before carrying with feeder.The feed of making coal in the course of processing with washing of coal is an example, the dewatering of prior art is: set up a cover dehydration plant on the top of feeder, it comprises the dehydration gate that has dehydration comb hole and the trough that is connected as a single entity with the dehydration gate, the water receiving tank of accepting the trough draining, the gate actuator dewaters.Before delivering coal with feeder, start dehydration gate actuator earlier, use gate to place the coal bunker Hatch Opening, then water is can by gravity dirty naturally in the coal, and suitable gate comb hole enters trough, and then enters water receiving tank, is drained by water receiving tank at last.When dirty, then start dehydration gate actuator when anhydrous, gate is removed by the coal bunker Hatch Opening, start feeder and deliver coal.There is following shortcoming in the above solution: 1. set up a cover dehydration plant, make equipment investment increase, working space is increased.2. the dewater dehydration comb hole of gate is (the comb hole of existing all dehydration gates is not always the case) of fixing, and as being blocked by coal cinder, is difficult for mediation.3. the Bed for Fine Coal that enters in trough and the water receiving tank with water is deposited in bottom land, can cause drainage path to block, and it is very difficult to get rid of alluvial; Also be mixed with many Bed for Fine Coal in the water of draining on the other hand, this is the waste of coal, also contaminated environment.

The purpose of this utility model just is to provide a kind of improved vibrating feeder, itself has dehydrated structure, and this dehydrated structure can be regulated dehydration aperture, comb hole, the thin material that flows into dehydrated structure with water can not cause obstruction, can not discharge yet, but can be recovered in material feeding end.

The purpose of this utility model is achieved in that it comprises feed hopper and drives the vibrator that feed hopper vibrates, and is characterized in that: a, feed hopper base plate have dehydration combs, and the trough of the water that flowing through the dehydration comb is accepted in connection one below it; B, dehydration comb grid section two end axles respectively are connected in feed hopper, and each grid section all has weight; C, trough front end have slag-drip opening at feed hopper discharge gate downside, and the rear end has discharge port, and the place is provided with overflow weir in discharge port.Principle of work is: before the Vibration on Start-up device, utilize the dehydration comb on the feed hopper base plate to make material dewatering.Water flows in the trough, drains from the discharge port of trough again, is deposited on bottom land and mix the thin material that enters in the trough in water, must not stop by overflow weir and is drained by discharge port.Dehydration is finished, and then the Vibration on Start-up device carries out feed.

Advantage of the present utility model is: 1. feed hopper itself has dehydrated structure, has both saved equipment investment, and working space is dwindled, and improves operating environment.2. dehydrating effect is good, because the feed operation process also is accompanied by dehydration, and when the feed hopper double vibrations, because and the grid section that the feed bucket spindle connects has weight, gravitate is inevitable to be swung with respect to feed hopper, the water hole generation hypertonic of consequently combing changes, and therefore the dehydration comb is difficult stops up.3. free from environmental pollution, not containing or seldom contain thin material that thin material (being cut by the overflow weir in the trough) 4. deposits in the trough in the water of finally draining can discharge and obtain reclaiming (and water can be not from then on mouthful overflow) from row's mouth of trough.This makes when installing, and trough bottom land and level are angled just to be realized.The correlation factor that this certain angle is determined comprises thin material and moisture proportion, oscillation frequency, oscillation power thereof.With regard to the those skilled in the art of present technique field, be not difficult to determine.

Example of the present utility model is provided by accompanying drawing 1～3, below in conjunction with detailed description detail of the present utility model.

Fig. 1 is a kind of concrete structure scheme drawing of the present utility model.

Fig. 2 is that Fig. 1 is along A-A line cutaway view.

Fig. 3 is a schematic perspective view of the present utility model shown in Fig. 1,2.

According to Fig. 1～3, the utility model comprises feed hopper 2 and drives the vibrator 7 of feed hopper 2, it is characterized in that: feed hopper 2 base plates have the dehydration of being made up of some grid sections 5 and comb, two socket bearing 3 of each grid section 5, bearing 3 are fixed on 7 liang of side shields of feed hopper, and be big for avoiding noise, at two of grid section 5 installing noise elimination structure 4, each grid section 5 following also has 1 or several weights 10, should stagger in the weight position of adjacent grid section 5, in order to avoid collision during swing; Be provided with the trough 8 that is connected as a single entity with feed hopper 2 below dehydration is combed, the discharge gate lower edge of termination feed hopper 2 is provided with slag-drip opening 9 before trough 8, and the rear end is provided with discharge port 11, is provided with overflow weir 6 nearby in discharge port 11.During use, the utility model is arranged at below feed bin 1 Hatch Opening, makes trough 8 bottom surfaces and level be a certain angle, this angle is calculated according to factors such as material and moisture proportion thereof, oscillation frequency, oscillation powers, makes it to satisfy just; Have only thin material to discharge during feed work in the trough 8, and water can not overflow from slag-drip opening 9.When vibrator 7 did not start, the utility model was made dehydration equipment and is used, and the water in the material is combed from dehydration and flowed into trough 8, then drained from discharge port 11, and the thin material that flows into water is hampered by overflow weir 6 and can drain from discharge port 11.After vibrator 7 started, feed hopper 2 was started working, and dehydration is still followed and carried out.Because the effect of weight 10, grid section 5 stirs with respect to dehydration comb face during vibration, and the hole of promptly combing, the slit that adjacent grid section is 5 produces hypertonic and changes, and result's hole total energy of combing keeps mediation.
