Abstract
The utility model relates to a fire coal particle screening feeding device, mainly comprises a hopper and a conveyor belt disposed below the hopper. Fire coal particles are conveyed downwards to the conveyor belt in a centralized manner via the hopper and fire coal is conveyed to a fire furnace via the conveyor belt. In order to perform the layering of fire coal with different diameters, fire coal particles with relatively large diameter are located at the lower part and fire coal particles with relatively small diameter are located at the upper part. A sieve plate is disposed between the hopper and the conveyor and the diameters of sieve apertures of the sieve plate gradually become larger from top to bottom. The sieve plate can be divided into several matrixes with different sieve aperture diameters from top to down. In order to prevent the fire coal from falling at too high a speed which reduces the screening efficiency of the sieve plate, the angle between the sieve plate and the horizontal plane is an acute angle. The fire coal particle screening feeding device of the utility model has the advantages of high automatic control degree, higher fire coal combustion efficiency, less fuels, less environmental pollution and less production cost for enterprises.
Description
Technical field
The utility model relates to a kind of feed arrangement, particularly a kind of coal-fired particle screening feed arrangement.
Background technology
The utility model relates to the apparatus field that material is supplied with, particularly coal-fired supply arrangement, existing coal-fired supply arrangement is that the screening of fire coal not being carried out granular size is burnt with regard to directly sending in the burner, causes the partial fuel coal burning insufficient, can not make full use of the coal-fired heat that is produced.Cause great waste to enterprise like this, also can further increase environmental pollution simultaneously.
On the other hand, existing facilities fail is controlled the into amount of coal, need have the staff to observe in the stove coal-fired combustion case for a long time and notifies other staff to deliver coal or stop to deliver coal.The working dynamics that not only strengthens the staff also needs to increase unnecessary staff, increases production cost.
In sum: need a kind of automatic controlling level height at present, can improve the feed arrangement of fired coal combustion efficient.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, designs a kind of automatic controlling level height, can improve the coal-fired particle screening feed arrangement of fired coal combustion efficient.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of coal-fired particle screening feed arrangement, its primary structure comprise a hopper and a conveyer belt that is arranged on the hopper below, and coal-fired particle is concentrated downwards by hopper and transmitted, and delivers on the conveyer belt and transports fire coal by conveyer belt to burner.In order to allow the fire coal with the different-diameter size carry out layering, layered mode is that bigger coal-fired particle is positioned at the below, and diameter is less is positioned at the top.So be provided with a sieve plate between hopper and conveyer belt, the diameter of the sieve aperture of sieve plate from top to bottom increases gradually.Sieve plate can be the matrix of the several different-diameter sieve apertures of layering from top to bottom.Too fast in order to prevent coal-fired falling speed, the screening effeciency of reduction sieve plate is an acute angle with sieve plate and horizontal plane angle.
What be provided with in the hopper that poking device controls hopper advances coal speed, and described poking device is made up of cylinder and many material togglings rods being provided with on the cylinder, and cylinder and hopper are coupling.Utilize the rotating speed of Electric Machine Control cylinder just can directly control the efficient of whole supply of equipment fire coal.
The hopper outside is provided with a scraper gate, and the scraper gate is positioned at the top of conveyer belt, and described scraper gate is to flexibly connect with hopper.The staff adjusts the height of stacking fire coal on the conveyer belt according to the distance that the concrete function situation of equipment is adjusted between scraper gate and the conveyer belt.
The structure that the utility model piles up with backing plate at existing copper-clad plate redesigns, possess following products characteristics and advantage: the utlity model has the automatic controlling level height, can improve fired coal combustion efficient, fuel savings reduces environmental pollution, for enterprise saves production cost.
Description of drawings
Fig. 1 is the utility model embodiment one structural representation;
Fig. 2 is the utility model embodiment one sieve-plate structure schematic diagram;
Fig. 3 is the utility model embodiment two structural representations.
The specific embodiment
Embodiment one: as shown in Figure 1, primary structure comprises a hopper 1 and a conveyer belt 2 that is arranged on hopper 1 below, and coal-fired 9 particles are concentrated downwards by hopper 1 and transmitted, and deliver on the conveyer belt 2 and transport coal-fired 9 by conveyer belt 2 to right road.In order to allow the fire coal 9 with different-diameter carry out layering, layered mode is that bigger coal-fired particle is positioned at the below, and diameter is less is positioned at the top.So between hopper 1 and conveyer belt 2, be provided with a sieve plate 3; As shown in Figure 2, the diameter of the sieve aperture 4 of sieve plate 3 from top to bottom increases gradually.
As shown in Figure 1, too fast in order to prevent coal-fired 9 fallings speed, the screening effeciency of reduction sieve plate 3 is acute angle with sieve plate 3 with horizontal plane angle a.
Embodiment two: as shown in Figure 3, the structure of present embodiment and embodiment one is basic identical, its difference is to be provided with in the hopper 1 that poking device 5 controls hopper 1 advances coal speed, and described poking device 6 is made up of cylinder 6 and many material togglings rods 7 being provided with on the cylinder 6, and cylinder 6 and hopper 1 are coupling.Utilize the rotating speed of Electric Machine Control cylinder 6 just can directly control the efficient of whole supply of equipment fire coal.
As shown in Figure 3, because the diameter of sieve aperture 4 increases gradually on the sieve plate 3, the fire coal 9 that diameter is bigger can drop at the front end of conveyer belt 2, and less meeting is dropped at conveyer belt 2 middle parts, is that diameter increases gradually from the bottom to top so the heap of the fire coal on the conveyer belt 29 is put.Stacking too high fire coal 9 on the conveyer belt 2 can be wipeed off by scraper gate 8.
