Description
Technical field
The utility model relates to the automatic coaling gear of dry-mixed mortar plant continous way, is applicable to various dry-mixed mortar plants.
Background technology
The heat that dry-mixed mortar plant adopts coal dust firing to emit is dried cold sand material, and the serviceability of coal dust conveying device is directly connected to the drying effect of cold sand material.At present, mainly there is following deficiency in the coal dust conveying device that people adopted: (1) coaling belt conveyor and transition coal bunker do not match, or are the coal supply deficiencies that makes that the coal powder injection machine is required, or are to make that the coaling belt conveyor starting is frequent, poor reliability, and power consumption is high; (2) can not open, stop coaling belt conveyor automatically according to what of coal amount in the transition coal bunker, automaticity is low.
Summary of the invention
The purpose of this utility model is the weak point that overcomes in the prior art, provides a kind of simple in structure, good reliability, and it is low to consume energy, the automatic coaling gear of dry-mixed mortar plant continous way that automaticity is high.
For achieving the above object, the automatic coaling gear of the utility model dry-mixed mortar plant continous way, comprise coal-grinding and powder-spraying machine, coaling belt conveyor, last coal bunker, described coal-grinding and powder-spraying machine top is provided with the transition coal bunker, the square groove that the top of transition coal bunker is welded to each other by four block plates, its underpart is welded to each other into up big and down small taper type bucket by four block plates, and square groove and taper type bucket are welded to each other together, and the coal feed point of taper type bucket lower end coal outlet and coal-grinding and powder-spraying machine connects; The charging belt machine is obliquely installed between last coal bunker and transition coal bunker, and the upper end of charging belt machine and transition coal bunker connect, and its lower end side places the outlet below of coal bunker.
On the described square groove level-sensing device is installed; On the described taper type bucket level-sensing device is installed down; The horizontal tilt angle of described charging belt machine is 15 °～18 °; Described taper type bucket lower surface of going up coal bunker is skewed, and the angle of inclination is identical with the angle of inclination of coaling belt conveyor.
Beneficial effect: because coaling belt conveyor and transition coal bunker coupling are rationally, and upper and lower level-sensing device is set on the transition coal bunker, avoided the Fraquent start of coaling belt conveyor, according to coal-fired quantity in the transition coal bunker, automatically open, stop coaling belt conveyor, reach the purpose of energy-conserving and environment-protective.It is simple in structure, good reliability, and it is low to consume energy, and the automaticity height is easy to maintenance.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: the 1-coal-grinding and powder-spraying machine; Level-sensing device under the 2-; The last level-sensing device of 3-; 4-transition coal bunker; The 5-coaling belt conveyor; The 6-support; The last coal bunker of 7-.
The specific embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
The automatic coaling gear of the utility model dry-mixed mortar plant continous way, mainly by coal-grinding and powder-spraying machine 1, transition coal bunker 4, coaling belt conveyor 5 and last coal bunker 7 constitute, transition coal bunker 4 is located at the top of coal-grinding and powder-spraying machine 1, the taper type bucket lower surface of last coal bunker 4 is skewed, the angle of inclination is identical with the angle of inclination of coaling belt conveyor 5, the square groove that the top of transition coal bunker 4 is welded to each other by four block plates, its underpart is welded to each other into up big and down small taper type bucket by four block plates, square groove and taper type bucket are welded to each other together, and the coal feed point of taper type bucket lower end coal outlet and coal-grinding and powder-spraying machine 1 connects; Level-sensing device 3 is installed on the square groove of transition coal bunker 4, level-sensing device 2 is installed down on the taper type bucket; Charging belt machine 5 is obliquely installed between last coal bunker 7 and transition coal bunker 4, and the horizontal tilt angle of charging belt machine 5 is 15 °～18 °.The upper end of charging belt machine 5 and transition coal bunker 4 connect, its lower end side places the outlet below of coal bunker 7, and last coal bunker 7 is located on the support 6, and support rides on the charging belt machine 5, the discharging opening of last coal bunker 7 is obliquely installed, and its inclination angle is identical with the inclination angle of charging belt machine 5.
During work, the coal in the last coal bunker 7 is packed into by loading machine, and after electric-control system started coaling belt conveyor 5, coaling belt conveyor 5 rotated around corresponding rolling wheel under motor-driven, and the coal that frictionally will be gone up coal bunker 7 discharging openings whereabouts is delivered among the transition coal bunker 4; The coal that stores in the transition coal bunker 4 enters the inlet of coal-grinding and powder-spraying machine 1 through its discharging opening, and sprays from its outlet after coal duster 1 grinds.Because coaling belt conveyor 5 coal-feeding quantities are bigger than the injecting coal quantity of coal duster 1, then the coal storage of transition coal bunker 4 can increase gradually; When the coal storage of transition coal bunker 4 reached the height of level-sensing device 3 settings, electric control system controls coaling belt conveyor 5 stopped automatically; But when the coal storage of transition coal bunker 4 dropped to the height of level-sensing device 2 settings, electric control system controls coaling belt conveyor 5 started automatically.
