Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model discloses a coal discharging device at the lower opening of a coal chute, as shown in figure 1, comprising a first coal discharging movable fan 4 and a second coal discharging movable fan 5 which are arranged at the opening part of a coal chute mouth; the first coal discharge movable fan 4 comprises a first arc-shaped bottom plate, an arc-shaped opening of the first arc-shaped bottom plate faces the upper part of the coal sliding nozzle, two sides of the first arc-shaped bottom plate are hinged to the shaft pins 1 through side plates, and the shaft pins 1 are arranged on the inner wall of the upper part of the coal sliding nozzle; the second coal discharge movable fan 5 comprises a second arc-shaped bottom plate, the arc-shaped opening of the second arc-shaped bottom plate faces the upper part of the coal sliding nozzle, and two sides of the second arc-shaped bottom plate are hinged on the shaft pin 1 through side plates; the first arc-shaped bottom plate and the second arc-shaped bottom plate are partially overlapped and jointly seal the coal sliding nozzle, and the second arc-shaped bottom plate is positioned on the outer side of the first arc-shaped bottom plate; the side edge of the second arc-shaped bottom plate, which is far away from the first arc-shaped bottom plate, is attached to the inner surface of the first side wall of the coal sliding nozzle, the arc-shaped opening surface of the first arc-shaped bottom plate is in sliding connection with the bottom surface of the second side wall of the coal sliding nozzle, and the first side wall and the second side wall are oppositely arranged; the first arc-shaped bottom plate and the second arc-shaped bottom plate are both used for rotating by taking the shaft pin 1 as a base point so as to open/close the coal chute mouth and further realize the discharge/storage of raw coal in the coal chute.
The utility model discloses an opening or sealing of swift current coal mouth is realized to first coal caving activity fan and second coal caving activity fan to, first arc bottom plate and second arc bottom plate through with first coal caving activity fan and second coal caving activity fan set up to the arc, and set up it and use the pivot to rotate as the basic point, reduce the thrust that needs when opening the coal mouth, make things convenient for the opening coal caving.
The existing coal chute baffle is generally a flat plate arranged horizontally, and when the coal chute baffle needs to be opened, horizontal pushing force or pulling force needs to be applied to the flat plate and the pressure of raw coal in a coal chute hole is born. In this embodiment, the first arc-shaped bottom plate and the second arc-shaped bottom plate are obliquely arranged, and the free edge of the first arc-shaped bottom plate is higher than the free end of the second arc-shaped bottom plate, when the coal sliding nozzle needs to be opened for coal discharge, because the second movable fan 5 is independent, and the second movable fan needs an oblique upward pushing force or pulling force, that is, the original horizontal force is divided into two parts, one part is an oblique upward force, and the other part is an oblique downward force, only the oblique upward force is needed in the present application, and the oblique upward force is a part of the original horizontal pushing force, so that the force consumption is reduced. Moreover, the area of the second movable fan 5 is smaller than that of the original horizontal baffle plate, and the pressure applied to the second movable fan is necessarily reduced. Moreover, when the second movable fan 5 opens a gap, the raw coal in the coal sliding nozzle flows out from the gap, and at the moment, part of the pressure of the raw coal seeps out along with the flowing coal, so that the pressure of the raw coal is further reduced. Therefore, use the utility model discloses a first activity fan 4 and the design of second activity fan 5, for former horizontal baffle, it is more laborsaving to operate, and is more convenient.
In this embodiment, a baffle 3 is disposed on an outer side surface of the first arched bottom plate, and the baffle 3 is located on a rotation track of the second arched bottom plate. When opening the in-process of second activity fan 5, baffle 3 can be touched to its side, and then can receive the resistance of baffle 3, at this moment, when the flow of raw coal was not enough, can continue to the second activity fan 5 application of force, and then drive first activity fan 4 and rotate simultaneously, enlarge the opening of swift current coal mouth, increase the flow of raw coal, and the same reason also can adjust the flow of raw coal and diminish.
Specifically, the second movable fan 5 has a plurality of opening modes, in this embodiment, a first coal discharging handle 8 is arranged on a side plate connected to the first arc-shaped plate, the first coal discharging handle 8 is rod-shaped, one end of the first coal discharging handle is fixed on the side plate, and the other end of the first coal discharging handle is located outside the coal sliding nozzle. Through first caving coal handle 8, can realize the location of first activity fan 4, through the first handle 8 of caving coal of external force push-and-pull, first activity fan 4 rotates for pivot 1, because the arc internal surface of first arc bottom plate and the second lateral wall bottom surface sliding connection of swift current coal mouth, so, when first activity fan 4 rotated, the internal surface of first arc bottom plate moved for the first lateral wall bottom surface of swift current coal mouth, and then realized opening of swift current coal mouth, put the coal. On the other hand, in order to realize the positioning of the first movable fan 4, when the first movable fan 4 and the second movable fan 5 seal the coal sliding port, the baffle 3 and the side edge of the second arc-shaped bottom plate have a certain distance, so that the second movable fan 5 can rotate a certain distance in the direction of the first movable fan 4, and the opening of the coal sliding port is also realized.
And a second coal discharging handle 2 is arranged on the side plate connected with the second arc-shaped plate, the second coal discharging handle 2 is rod-shaped, one end of the second coal discharging handle 2 is fixed on the side plate connected with the second arc-shaped plate, and the other end of the second coal discharging handle is positioned outside the coal sliding nozzle. Through setting up this second coal discharging handle 2, can be keeping away from smooth coal mouth opening play realization coal discharging, and then reduce operating personnel's operational risk. Avoiding burying operation staff when thin goods (namely water coal) exist in the raw coal. More specifically, the length of the second coal discharging handle 2 is more than or equal to 5m, the distance is more than 2 times of the width of the coal sliding nozzle, the safety can be further improved, and when an accident occurs, operators have enough time to avoid the coal sliding nozzle.
In order to increase the conveying efficiency of the raw coal, a conveying belt 7 is arranged below the coal sliding nozzle and directly conveys the raw coal flowing out of the coal sliding nozzle to a coal conveying vehicle.
This device still includes hydraulic push rod, and hydraulic push rod's power take off end is connected at the free end of coal discharging handle 2, and hydraulic push rod is used for driving the motion of coal discharging handle 2, and then drives second coal discharging activity fan 5 and rotates to open the coal chute mouth coal discharging. Through hydraulic push rod, can remove operating personnel from and exert force to putting coal handle 2, promote fortune coal mechanization degree, reduce the human labor, the staff only need be at the operating switch of remote operation hydraulic push rod, also can increase staff operational safety nature.
