Abstract
The utility model relates to a dust-removing equipment, in particular to a dust remover for excavator which is installed on a coal gate machine to eliminate dust on the working face and to improve mining working environment, comprising a body, a dust exhausting fan and an electrical machine. A spray nozzle (4) and a filter (3) is arranged in a body (6) and the filter (3) is installed vertically on the rear end of the body (6). The utility model changes the dust removal medium from a common water curtain to a water spray of multipoint spray and omnidirectional coverage, and a filter screen which is used for obstinacy granules to cross is added in the dust remover. Thus, dust collection efficiency can be improved greatly and the defect that the dust collection efficiency of the departed dust remover is low can be eliminated. Thus, the working environment can be improved greatly and the delicate appearance structure and the proper mounting position can solve the abuse of small space, difficult installation and inconvenient movement.
Description
Technical field
The utility model relates to dust arrester, specifically is a kind of being installed on the coal tunnelling machine, eliminates the face dust, improves the development machine deduster of mining work environment.
Background technology
On the development machine work plane,, generally adopt the atomizing de-dusting system at present for reducing dust from flying, improving the operating point visibility.But,, still have big dust to exist along with cutting, loading, conveying to coal petrography.Therefore, need have other dust arresters.For guaranteeing downhole safety, the wet dust removals that adopt more, its structure is under the suction function that produces at blower fan, the flue gas that contains big dust is flowed through, and water curtain filters, washing, grit is adhered to and inter coagulation mutually, and the device that grit is separated, but this deduster efficiency of dust collection is lower, and volume is bigger, increases burden for less space, down-hole.
The utility model content
Efficiency of dust collection is low in order to solve, volume takies bigger problem, and the utility model provides a kind of deduster.This deduster is good dedusting effect not only, and by contour structures, appropriate installation site address the above problem cleverly.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of development machine deduster has body, dedusting fan, motor, establishes spray nozzle and strainer in the body, and strainer vertically is installed on After-Body.
Described spray nozzle is solid and is uniformly distributed in the body with horizontal three rows, vertical three row, three layers of short transverses.
Described dedusting fan is a forward multiple wing formula centrifugal blower.
Described motor is installed on the blower fan rear side.
Described deduster is installed in development machine rear body, the second transporter bottom, and deduster and second transporter adopt flexible the binding (as iron chains etc.), can make the deduster and the second transporter relative motion, to adapt to ground differing heights requirement.
Universal wheel is installed in described deduster bottom.
Described organism bottom is the funnel type structure.
The beneficial effects of the utility model are:
1, the utility model with the dedusting medium by common water curtain, change the water smoke of multiple spot ejection, comprehensive covering into, and be added with the screen pack that the obstinate particle of protection passes through in deduster inside, efficiency of dust collection is largely increased, overcome the low shortcoming of deduster efficiency of dust collection in the past, improve working environment greatly.
2, dedusting fan of the present utility model adopts the forward multiple wing formula centrifugal blower of international most advanced level, and the inlet and outlet employing is advanced, side goes out mode, and motor is installed by common top formula and changed the rear portion installation into.Two thus, deduster height of contour and width be can reduce greatly, thereby development machine rear portion, the second transporter bottom deduster can be installed in, under the bottom universal wheel supports, advance and retreat synchronously in company with development machine, make compact conformation, conveniently moving.
Description of drawings
Fig. 1 is a structure principle chart of the present utility model.
Fig. 2 is that the utility model and development machine body link schematic diagram.
Among the figure, 1 is induced pipe; 2 is universal caster wheel; 3 is strainer; 4 is spray nozzle; 5 is blower fan; 6 is body; 7 is motor; 8 is air intake; 9 is the development machine body; 10 is second transporter; 11 is deduster.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, a kind of development machine deduster, have body 6, dedusting fan 5, motor 7, establish spray nozzle 4 and strainer 3 (screen cloth) in the body 6, strainer 3 vertically is installed on body 6 rear portions, and spray nozzle 4 is with horizontal three rows, vertical three row, three layers of short transverses, being three-dimensional evenly distributes, amount to 27 spray nozzles, dedusting fan 5 is a forward multiple wing formula centrifugal blower, and motor 7 is installed on the blower fan rear side.
The course of work of the present utility model is as follows:
Induced pipe 1 links to each other with the air intake 8 of being located at front part of a body, dust point off density.When blower fan 5, when motor 7 rotates and produces negative pressure, ash-laden gas enters deduster body 6 inside thus.Before this, open the press water switch, realize spraying by spray nozzle 4.Solid particle in the flue gas fully contacts with intensive, equally distributed drop, liquid film, bubble etc., and grit adheres to mutually and condenses, and then falls within body 6 bottoms with liquid.Obstinate particle for part moves on is blocked when running into strainer 3, and washes away inflow body 6 bottoms down at water smoke.Body 6 bottoms are the funnel type structure, are beneficial to dust-laden sewage, mud is discharged by scavenge port.
For guaranteeing deduster 11 and development machine body 9 collaborative advance and retreat, be provided with universal caster wheel 2 in deduster 11 bottoms.
As shown in Figure 2, induced pipe 1 front end is an air intake 8, induced pipe 1 is communicated with deduster 11, deduster 11 is installed in development machine body 9 rear portions, second transporter, 10 bottoms, for guaranteeing that deduster 11 adapts to rugged ground in the tunnel, the deduster 11 and second transporter 10 adopt the flexible binding of iron chains.
Claims (7)
