Description
Technical field
The present invention relates to coal burner field, a kind of beans is pulverized conveyer specifically.
Background technology
At present, coal remains main fuel energy.The lumped coal that is mostly bulk of commonly using at present, also have the beans of writing with fritter, the granular size of coal directly affects burning of coal efficiency, thereby directly affects heat exchange efficiency and the heat production efficiency of boiler or burner, therefore, for beans particle, further pulverizing can improve its combustion efficiency.Existing coal device general structure in small, broken bits particle very complicated and in small, broken bits is larger, in coal dust is carried, owing to being difficult to control transporting velocity and dynamics, thereby is easy to cause conveyance conduit to stop up simultaneously.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of simple in structure, carry convenient and coal dust effective beans in small, broken bits to pulverize conveyer.
For solving the problems of the technologies described above, beans of the present invention is pulverized conveyer and is comprised that front end offers beans entrance, the casing of discharge is offered in rear end, its design feature is that described casing is cylindric and horizontally set, the inner chamber of casing by casing before after orifice plate and casing orifice plate from A-P, be separated into the broken coal chamber being interconnected, chamber in small, broken bits and conveyor chamber, in described broken coal chamber, be rotatablely equipped with by broken coal motor and drive the transfer roller rotating, a plurality of quartering hammers gather on the cylinder of transfer roller, casing posterior rotation is provided with by motor in small, broken bits and drives the rotating shaft of rotating, rotating shaft is crossed in conveyor chamber and chamber in small, broken bits and rotating shaft blade in small, broken bits is being installed in chamber in small, broken bits, pectinid blade is installed in conveyor chamber.
Adopt said structure, first coal grain enters broken coal chamber, under knocking, the rotation of coal hammer carries out primary breakup, enter again afterwards in chamber in small, broken bits further in small, broken bits under the effect of blade in small, broken bits, finally enter conveyor chamber, under the effect of pectinid blade, from discharge, flow out, in whole process, the mobile power of coal dust is produced by the rotation of pectinid blade; By controlling the velocity of rotation of broken coal motor, control the broken speed of beans, by controlling the velocity of rotation of motor in small, broken bits, control the granularity of coal dust and the speed that pectinid is carried, simple in structure, it is convenient to control.
The front end of described rotating shaft extend in broken coal chamber, on the rear end face of transfer roller, offers groove, and the front end of rotating shaft is automatically connected in groove by bearing rotary.Rotating shaft and transfer roller can relatively rotate, and both ends can be supported mutually, make structure more firm.
Described rotating shaft is rotatably connected on the center of the front orifice plate of casing, and before casing, on orifice plate, spacer ring is established a plurality of through holes; After casing, through hole is offered at the center of orifice plate.
On described beans entrance, coal feeding bucket is installed.Coal feeding bucket is set, has facilitated stoking.
The chamber orifice body that through hole is offered by polylith center in described chamber in small, broken bits is separated into a plurality of element cells in small, broken bits, in rotating shaft, in each element cell in small, broken bits, blade in small, broken bits is all installed.Fine chamber is divided into a plurality of element cells, better effects if in small, broken bits.
In sum, the present invention has advantages of that simple in structure, conveying facilitates and coal dust is in small, broken bits effective.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
Fig. 1 is the structural representation of one embodiment of the present invention.
The specific embodiment
With reference to accompanying drawing, beans of the present invention is pulverized conveyer and is comprised that front end offers the casing 1 that beans entrance 17, rear end are offered discharge 18, for the ease of stoking, coal feeding bucket 7 is installed on beans entrance 11.Meanwhile, on discharge 18, be connected with conveyance conduit, conveyance conduit is connected to coal burner or boiler.Casing 1 is cylindric and horizontally set, the inner chamber of casing 1 by casing before after orifice plate 2 and casing orifice plate 3 from A-P, be separated into broken coal chamber 4, chamber in small, broken bits 5 and the conveyor chamber 6 being interconnected, in broken coal chamber 4, be rotatablely equipped with by broken coal motor 7 and drive the transfer roller 8 rotating, a plurality of quartering hammers 9 gather on the cylinder of transfer roller 8, for the shape of quartering hammer 9, can comprise that the hammer body of column and the taper that is located at hammer body two ends knock portion.Casing 1 posterior rotation is provided with by motor 10 in small, broken bits and drives the rotating shaft 11 of rotating, and rotating shaft 11 is crossed in conveyor chamber 6 and chamber in small, broken bits 5 and rotating shaft 11 and blade 12 in small, broken bits is being installed in chamber 5 in small, broken bits, pectinid blade 13 is installed in conveyor chamber 6.
In said structure, first coal grain enters broken coal chamber 4, under knocking, the rotation of coal hammer 9 carries out primary breakup, enter again afterwards in chamber 5 in small, broken bits further in small, broken bits under the effect of blade 12 in small, broken bits, finally enter conveyor chamber 6, under the effect of pectinid blade 13, from discharge 18, flow out, in whole process, the mobile power of coal dust is produced by the rotation of pectinid blade 13; By controlling the velocity of rotation of broken coal motor 7, control the broken speed of beans, by controlling the velocity of rotation of motor 10 in small, broken bits, control the granularity of coal dust and the speed that pectinid is carried
