Description
Technical field
The utility model relates to mass transport field, particularly, relates to a kind of coal belt conveyor system.
Background technology
The Anti-blockage measure of the material-transporting system of conventional belt machine mainly uses Anti-blockage detector switch, is arranged in the hopper side walls of the transfer line of belt conveyer head, leaks stream situation in coal bunker in order to monitoring.When funnel blockade, material level rises, and monitor sends signal and cuts off conveyer power supply, thus avoids accident to occur.There is blind area in existing arranging of belt conveyor switch, causes blocking alarming not in time.Traditional design selects product to be side plate pressure sensor putty switch, and effect is undesirable in actual use, occurs misoperation in operation process, affects production efficiency, and occurs the situation that true putty is not reported to the police.This putty switch installation site is too high, if when there is putty situation, is substantially full of by coal in funnel and chute, increases the heavily loaded pressure restarting belt feeder and bring.
Therefore, need to provide a kind of coal belt conveyor system can clearing up blocking fast.
Utility model content
The purpose of this utility model is to provide a kind of coal belt conveyor system can clearing up blocking fast.
To achieve these goals, the utility model provides a kind of coal belt conveyor system, comprise the belt conveyor of the continus convergence realizing coal, funnel and elephant trunk, wherein, described coal belt conveyor system also comprises the air bubble be installed on described elephant trunk or funnel, this air bubble has freeing pipe, the end of this freeing pipe is connected with nozzle, described freeing pipe stretches in described elephant trunk, and described nozzle is arranged as towards the corner in the junction between described elephant trunk and described funnel and/or described elephant trunk in described elephant trunk.
Preferably, described elephant trunk comprises the first pipeline section and the second pipeline section, described first pipeline section connects described funnel and vertically extends downwards, described second pipeline section connects described first pipeline section and extends obliquely, described air bubble is installed on outside described first pipeline section, and described nozzle aims at the described corner between described first pipeline section and the second pipeline section obliquely.
Preferably, described air bubble is arranged so that the air flow line of this nozzle is identical with the flow direction of described coal.
Preferably, check valve is provided with in described freeing pipe.
Preferably, described air bubble also comprises the controller opened and closed for controlling described check valve.
Preferably, described air bubble is provided with the compression indicator of the pressure of the exit flow for showing described nozzle.
Pass through technique scheme, by arranging air bubble near the funnel exit and Elephant trunk turning place of belt conveyor system, thus air bubble can be opened use high pressure draft to break coal blocking at funnel exit and Elephant trunk turning place, do not need to dismantle delivery system, cleaning blocking fast effectively, improves work efficiency.
Other feature and advantage of the present utility model are described in detail in detailed description of the invention part subsequently.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for specification sheets, is used from explanation the utility model, but does not form restriction of the present utility model with detailed description of the invention one below.In the accompanying drawings:
Fig. 1 is the coal belt conveyor system according to a kind of detailed description of the invention of the present utility model.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
As shown in Figure 1, a kind of coal belt conveyor system, comprise the belt conveyor of the continus convergence realizing coal, funnel 3 and elephant trunk 1, wherein, described coal belt conveyor system also comprises the air bubble 2 be installed on described elephant trunk 1 or funnel 3, and air bubble 2 has freeing pipe, and the end of this freeing pipe is connected with nozzle, described freeing pipe stretches in described elephant trunk 1, and described nozzle is arranged as towards the junction between described elephant trunk 1 and funnel 3 and/or the corner in described elephant trunk 1 in described elephant trunk 1.In this coal belt conveyor system, the coal (being in most cases full-bodied coal dust) of being come by Belt Conveying falls and funnel 3, is then transported to next stage unit by elephant trunk.
Extend into the described nozzle of the described freeing pipe end in elephant trunk 1 by air bubble 2, high pressure gas can be transported in elephant trunk 1 by air bubble 2, get through described coal (especially heavy body coal dust) blocking.Usually, the exit of funnel 3 diminishes due to delivery duct internal diameter, therefore easily blocks, also easily block at elephant trunk 1 and turning in addition, therefore need to arrange air bubble 2 at this type of near sites, to break through blocking by high pressure draft, ensure the normal operation of transportation work.
According to a kind of detailed description of the invention of the present utility model, elephant trunk 1 comprises the first pipeline section 11 and the second pipeline section 12, first pipeline section 11 connects funnel 3 and vertically extends downwards, second pipeline section 12 connects the first pipeline section 11 and extends obliquely, air bubble 2 is installed on outside the first pipeline section 11, and described nozzle aims at the described corner between described first pipeline section 11 and the second pipeline section 12 obliquely.Other similar turning structure places need to install air bubble 2 to clear up after blocking too.
Particularly, air bubble 2 is arranged so that the air flow line of this nozzle is identical with the flow direction of described coal, so that air-flow more effectively impacts the described coal (full-bodied coal dust) of blocking, breaks blocking.
In addition, in described freeing pipe, be also provided with check valve, be drawn back in air bubble 2 via described nozzle and described freeing pipe to prevent the coal in delivery duct and cause unnecessary damage.
In addition, air bubble 2 also comprises the controller opened and closed for controlling described check valve, therefore can close air bubble 2 when described delivery duct is under normal working, prevent the resorptions such as coal dust.
In order to regulate the pressure of the output gas flow of air bubble, air bubble 2 is provided with the compression indicator of the pressure of the exit flow for showing described nozzle, characterizes the pressure of the air-flow exported according to this compression indicator, regulates the air-flow of air bubble 2 to export.
Below preferred implementation of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition, each concrete technical characteristic described in above-mentioned detailed description of the invention, in reconcilable situation, can be combined by any suitable mode, in order to avoid unnecessary repetition, the utility model illustrates no longer separately to various possible array mode.
In addition, also can carry out combination in any between various different embodiment of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
