Abstract
The utility model relates to a coal feeder, in particular to a chute type coal feeder. The chute type coal feeder comprises a blanking trough and two gates, and is characterized in that the two gates are installed on the blanking trough, a bulkhead gate is arranged on the upper portion of the blanking trough, a jaw gate is arranged on the lower portion of the blanking trough, a bulkhead gate oil cylinder for controlling the opening of the bulkhead gate and a jaw gate oil cylinder for controlling the opening of the jaw gate are arranged on the blanking trough, the lower jaw gate is used for controlling coal quantity, and the upper gate is open all the time, and closed only when the jaw gate is out of control or damaged so that the coal quantity can not be out of control and a belt can not be badly pressed. By means of the chute type coal feeder, the phenomenon that cleaned coal in existing coal feeders is poured out is completely eliminated, working environments are improved, and maintenance intensity and labor intensity are reduced; the chute type coal feeder is installed at the bottom of a coal bunker, coal can automatically flow out under the effect of gravity after the gates are opened by the aid of a working principle of flowing automatically under coal pressure in a silo, and a power source is not required in the whole coal unloading process; the chute type coal feeder is compact in structure, high in conveying capacity, and capable of effectively saving using space if arranged under the cleaned coal bunker.
Description
Technical field
The utility model relates to a kind of feeder, specifically a kind of chute type feeder.
Background technology
Vibrations feeder and reciprocating coal feeder have a lot of shortcomings, and old-fashioned feeder needs to bear the friction force that material is very large in operational process, so need larger driving power, energy consumption is large; Because power is large, structure stress is also large, and weight of equipment is large; Because feed process is reciprocal, shock motion, vibration equipment is large, and noise is also large; Because structure stress is large, movement parts quick abrasion, maintenance capacity is large; Because feed is inhomogeneous, production efficiency is low.
Reciprocating coal feeder adopts motor, reductor, bent axle to control the reciprocal operation of dustpan, make coal owing to sliding on belt under inertia, feeder bent axle is to taking turns due to stressed excessive at operational process, frequent breakage copper sheathing, to wheel pin, motor is also because environment for use is severe, Frequent Troubles, equipment maintenance cost is high, operating cycles is short.
Reciprocating coal feeder connects dustpan by bent axle, and dustpan moves on roller, and friction drag is large.Feeder dustpan long term wear, larger with original lower funnel gap, rare coal is constantly gushed out in operation process, and the unrestrained rare coal phenomenon of every coastiong is all very serious, and health amount is very large.Roller causes operation to be obstructed owing to entering coal slime in using, and dustpan resistance strengthens.Reductor leakage of oil, copper sheathing, fast to the wheel pin wear-out period, all restricting the coal through washing in normal production run is stored in storehouse, large quantity of moisture flows out from feeder and Hatch Opening junction, the long-term trickle of feeder motor, insulation degree reduces greatly, and feeder and frame are caused to heavy corrosion, frame serious cracking, to production, brought hidden trouble, and in daily attention, due to stand stretch cracking, well damage to consumable accessory, operating cycles reduce half even 2/3rds, bring heavy burden to the plan of material accessory, need to change in time.
Summary of the invention
The purpose of this utility model provides the chute type feeder that a kind of equipment failure rate is low, operating cycles is long.
The utility model comprises blanking groove, gate, it is characterized in that installing on blanking groove twice gate: top is that bulkhgead gate, below are Hubei Province formula gate, the bulkhgead gate oil cylinder of controlling bulkhgead gate and opening, Hubei Province formula gate oil cylinder of controlling Hubei Province formula gate opening are also installed on blanking groove, and top bulkhgead gate is opening all the time, Hubei Province, below formula gate is used for controlling coal amount size, top bulkhgead gate is out of control at Hubei Province formula gate or cuts out damage in the situation that, is unlikely coal amount out of control so that kill belt.
Consider clean fine coal seepage problem, below blanking groove, make double-layer clapboard, internal layer is manufactured with water-guiding hole, and skin has gutter.Ponding can be discharged by projected route, reduce the current on belt.
The utility model compared with prior art has the following advantages:
Thoroughly eliminated feeder and gushed rare coal phenomenon, improved working environment, reduced contamination, the work that is conducive to turn round is healthy, has reduced maintenance intensity and labour intensity, is convenient to safeguard convenient operation after transformation; This kind of feeder can reduce the input of the equipment such as motor, reductor, bent axle and save a large amount of electric energy losses; Be arranged on coal bunker bottom, utilize silo coal to press the principle of work of gravity flow, after gate is opened, coal flows out voluntarily under Action of Gravity Field, and the whole process of unloading coal need not propulsion source; This compact equipment, operational throughput is large, this equipment is installed under cleaned coal storehouse and can be saved usage space by actv..
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the birds-eye view of Fig. 1.
In figure: 1. blanking groove, 2. bulkhgead gate, 3. Hubei Province formula gate, 4. bulkhgead gate oil cylinder, 5. Hubei Province formula gate oil cylinder.
The specific embodiment
The utility model is large for cleaned coal particle, the coal that viscosity is low can adopt blanking groove structure, utilize double disc to control, press coal store feed opening size blanking groove customized to 350mm left and right, belt top, twice gate is installed on blanking groove 1: top is bulkhgead gate 2, below is Hubei Province formula gate 3, on blanking groove 1, be also provided with and control the bulkhgead gate oil cylinder 4 that bulkhgead gate 2 is opened, control Hubei Province formula gate oil cylinder 5 that Hubei Province formula gate 3 is opened, Hubei Province, below formula gate 3 is used for controlling coal amount size, and top bulkhgead gate 2 is opening all the time, top bulkhgead gate 2 is out of control at Hubei Province formula gate 3 or cuts out damage in the situation that, be unlikely coal amount out of control so that kill belt.
Consider clean fine coal seepage problem, we,, below blanking groove 1, make double-layer clapboard, and internal layer is manufactured with water-guiding hole, and skin has gutter.Ponding can be discharged by projected route, reduce the current on belt.
By regulating Hubei Province formula gate, change openings of sizes, adjust coal conservation.
Claims (2)
1. a chute type feeder, comprise blanking groove, gate, it is characterized in that installing on blanking groove twice gate: top is that bulkhgead gate, below are Hubei Province formula gate, the bulkhgead gate oil cylinder of controlling bulkhgead gate and opening, Hubei Province formula gate oil cylinder of controlling Hubei Province formula gate opening are also installed on blanking groove, and top bulkhgead gate is opening all the time.
2. chute type feeder as claimed in claim 1, is characterized in that the below of described blanking groove is double-layer clapboard, and internal layer has water-guiding hole, and skin has gutter.
