Abstract
The utility model provides a coal-spilling resistant device of a belt feeder switching tower, which comprises a hopper and a conveying belt arranged in the blanking opening of the hopper; wherein, a coal-spilling detection device is arranged on the location of a body position near the inner side of the inlet of the hopper; the coal-spilling detection device comprises a pull switch and a blanking salver arranged on the pull switch. When material is plugged, a gravity generated by the spilled coals falling on the blanking salver which causes unbalance drives the pullswitch to move and give out a stopping signal for stopping the running of the belt feeder. As the hopper plugging situation of the hopper can be directly dissolved earlier and used as the large-stage protection for preventing the hopper from being perniciously plugged, the utility model has the detection rate approaching to 100 percent; a safe and reliable guarantee is provided for improving the production efficiency.
Description
Technical field
The utility model relates to a kind of belt feeder transferring tower coal overflow-proof apparatus that is used for bulk material delivery systems such as mine, metallurgy, electric power or harbour, the timely stoppage protection equipment in the time of effectively controlling the hopper obstruction.
Background technology
Belt feeder hopper anti-clogging fender guard is one of important safety method of belt conveyor system, if material can not in time detect and shut down after stopping up, not only has a strong impact on operating efficiency, and may cause the damage of equipment.
Usually various ways such as the anti-clogging fender guard of existing application in mine, metallurgy, electric power or harbour such as tilt switch, pressure measurement formula switch, blocking rotary type stuff level switch, itself technology comparative maturity.But exist a common problem to be in actual applications: can not directly detect the actual conditions of discharging point, and be mounted in certain location in the hopper.This position only when stopping up generation, just can have material to enter and cause switch motion just often not having material to impact.Belong to indirect detection.Since the problem of the presence states such as structure of hopper, and for existing anti-clogging fender guard, have blind spot in the monitored area.Particularly the sticking coal of rainy season, winter hopper, freeze under the more situation of coal, directly cause can reducing of hopper by the cross section, when the coal amount was big, material just formed when also the position of switch is stopped up in no show and stops up, and begins excessive in a large number.Therefore, seek a kind of energy efficient stable, the hopper detecting device that can just report to the police before accident worsens generation become the problem that presses for solution.
Summary of the invention
Situation in view of above-mentioned prior art, the utility model provides a kind of belt feeder transferring tower coal overflow-proof apparatus, it has and stop up to take place by hopper, and when failing to form coal excessive, realize that the control belt feeder is out of service, the next follow-up belt in ribbing that prevents to overflow in a large number amasss the coal situation in a large number, reduces the purpose that flow process starts difficulty once more.
For achieving the above object, the utility model provides a kind of belt feeder transferring tower coal overflow-proof apparatus, comprises hopper and is positioned at the load-transfer device of hopper blanking port; Wherein an excessive coal detecting device is installed near the body position place described hopper inlet is inboard; Described excessive coal detecting device comprises installs a blanking pallet on pullswitch and this pullswitch.When the material obstruction occurring, fall into generation gravity lack of equilibrium on the blanking pallet by the coal that overflows, the action of effect pullswitch provides shutdown signal, stops belt conveyer and moves.After hopper stopped up elimination, the blanking pallet was from horizontal reset, and belt conveyer continues operation.
In the utility model, the model of the pullswitch of indication is THL-II; Breakdown signal takes place in this switch under the effect of 0.9kg power.
According to scheme of the present utility model, the card of related blanking pallet is a plane body or a concavo-convex arc card body; Have on described parallel card body or the concavo-convex arc card body and let out the dirt hole.Can clean the dust impurity on the blanking pallet so naturally.
According to above-mentioned application characteristic, have inspection door in cooresponding hopper one side of described blanking tray position.Can conveniently observe the service condition of the coal detecting device that overflows like this.
In a word, belt feeder transferring tower coal overflow-proof apparatus of the present utility model utilizes a blanking holder and a pullswitch of accepting material to form; When stopping up by hopper, a small amount of excessive coal of generation drops into and makes it to take place skew one on the blanking pallet and cause the pullswitch action, provides shutdown signal, and the control band conveyor is out of service.Because of direct early detection hopper stopping state, the afterbody protection as preventing that pernicious hopper from stopping up has the verification and measurement ratio near 100%, provides safe and reliable guarantee to the raising of production efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing embodiment, the utility model will be further described.The accompanying drawing of giving only is to be used for reference and explanation usefulness, is not to be used to limit the utility model scope.
By belt feeder transferring tower coal overflow-proof apparatus shown in Figure 1, comprise that hopper 2 reaches in described hopper 2 entrance and the load-transfer device 1 between the chute.When falling into chute by inlet, the cylinder 7 of load-transfer device 1 by hopper 2, coal offers the outlet bottom that belt feeder (figure does not provide) is positioned at hopper 2.An excessive coal detecting device is installed in the position near the inlet top of described load-transfer device 1 cooresponding hopper 2; In the present embodiment, described excessive coal detecting device comprises the pullswitch 5 of setting, the blanking pallet 4 of a parallel card body is installed on the pivoted arm of its pullswitch 6 is formed.When hopper stops up, can drop on the blanking pallet 4 once excessive coal occurs.Action of gravity pullswitch 6 actions that utilize excessive coal to produce provide shutdown signal, and this shutdown signal offers belt feeder and stops the operation of belt feeder, has avoided the damage of belt feeder, has reduced the use cost of maintenance and replacing belt.In addition, consider that the coal detecting device that overflows is mounted in the inside of hopper 2, for ease of observing its normal operation, and being positioned at least one side has inspection door 3 on cooresponding hopper 2 bodies of coal detecting device that overflow.
In above-mentioned, the card of mentioned blanking pallet 4 can be selected the card of concavo-convex arc body for use except that plane body; In addition, on the card of described blanking pallet 4, have and let out dirt hole 5, be used for low amounts of dust and impurity on the nature cleaning blanking pallet 4, reduce and safeguard intensity.
Claims (2)
1, a kind of belt feeder transferring tower coal overflow-proof apparatus comprises hopper and is positioned at the load-transfer device (1) of hopper blanking port; It is characterized in that near excessive coal detecting device of the inboard body position place installation of described hopper (2) inlet; Described excessive coal detecting device comprises a upward installation blanking pallet (4) of pullswitch (6) and this pullswitch (6).
2, belt feeder transferring tower coal overflow-proof apparatus according to claim 1, the card that it is characterized in that described blanking pallet (4) are a plane body or a concavo-convex arc card body; Have on described parallel card body or the concavo-convex arc card body and let out dirt hole (5).
