Abstract

The utility model discloses an anti-blocking control device of a funnel, which overcomes the defects that in the prior art, the funnel for bulk production diversion of the belt conveying is easy to block, has large labor intensity of manual dredging, wastes human resource, and affects the operation efficiency and the equipment and human safety. The funnel is internally provided with a sensor for detecting the height of materials, and a vibration pump which is controlled to open and close by the sensor. When the height of the material in the funnel in the belt-conveying system is superhigh, the sensor controls the switch thereof to enable the power supply loop of the vibration pump to be powered-on so as to generate vibration, bulk and scattered materials are scattered and drop along the vibration of the vibration pump, so that the material can be prevented from being bonded and blocked, the dredging work in the funnel can be automatically completed, the manual tour and hand-hold stick dredging can be free, the human resource and high-intensity labor can be saved, the operation efficiency is high, and the safety of the equipment and personnel can be ensured.

Description

The anti-blocking automatic control device of funnel

Technical field

The utility model belongs to automatic control device, specifically a kind ofly prevents to transport the self-con-tained unit that bulk goods stops up with the funnel of belt feeder.

Background technology

Transporting of bulk goods such as harbour handling ore, coal finished operating efficiency height, broad covered area with belt goods delivery system.Because delivery conduit is long, the belt of belt transporter needs more piece to transfer continuously, and reprint with funnel the centre of belt switching link.When belt goods delivery system was finished bulk goods conveying task, the flow of goods was in the undulating state of near sinusoidal ripple.

The equipment of belt conveyor system loading and unloading fragmentary material, operating efficiency is subjected to the influence of instantaneous high flow capacity goods carrying capacity bigger, the big strand of material of moment can cause material bonding, the obstruction in the funnel, cause operation to be interrupted, influence the carrying capacity of goods, reduce the degree of utilization and the operating efficiency of system, even had influence on the safety of equipment itself.Present terms of settlement is, be provided with the tour worker in belt switching link, in case finding instantaneous high flow capacity goods arrives, will bond in funnel when stopping up, make an inspection tour the worker and dredge with regard to take drill rod ceaselessly to throw material downwards in funnel at once, so not only labour intensity is big, inefficiency, sometimes still can't resolve the blockage problem of funnel, cause the flow process operation to interrupt, influenced the transport efficiency of goods, manually feeding intake also exists potential safety hazard.

The utility model content

Technical problem to be solved in the utility model is, overcome prior art and transport the middle funnel of reprinting usefulness of bulk goods with belt feeder, because of the instantaneous high flow capacity of goods stops up by easily causing the goods in the funnel, artificial take that drill rod mediation labour intensity is big, the waste of manpower resource, influence the shortcoming of operating efficiency and equipment and personal safety, provide a kind of funnel anti-blocking automatic control device.

In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: in the funnel of the belt conveyor system of fragmentary material, be equipped with and be used to detect sensor that height of materials uses and the vibratory pump of controlling its start-stop by sensor.

The utility model also has following technical characterictic:

The start-stop of described sensor control vibratory pump, be in the current supply circuit of vibratory pump, to be connected with relay switch, on the control loop of vibratory pump, time relay coil and the switch serial connection of controlling by sensor, the Time Delay Opening contact of the open contact of intermediate relay and time relay and the coil tandem of relay; Above-mentioned two sequential circuit parallel connections, the coils from parallel connection of coils of intermediate relay is on the coil of time relay;

On described time relay coil and series arm, also be in series with switch by logic controller control by the sensor master cock;

On the open contact of described intermediate relay and control circuit that time relay Time Delay Opening contact is connected in series, be parallel with manual control button.

Advantage of the present utility model and good effect are, because in belt conveyor system is reprinted the funnel of usefulness, be equipped with and be used to detect sensor that the fragmentary material height uses and by the vibratory pump of sensor control, when the material superelevation in the belt conveyor system funnel in service, sensor is controlled its switch, the conducting of vibratory pump current supply circuit is produced vibration, fragmentary material makes material break up the whereabouts with the vibration of vibratory pump, play and prevent the material bonding, the effect of stopping up, automatically finish the mediation work of material in funnel, human resources and high-intensity work have been saved in not manual patrol and manpower mediation, the operating efficiency height has guaranteed equipment and personal safety.

Description of drawings

Fig. 1 is a mechanical installation site of the present utility model scheme drawing;

Fig. 2 is an electrical schematic diagram of the present utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Among Fig. 1, in the belt conveyor system of fragmentary material is reprinted the funnel 1 of usefulness, be equipped with and be used to detect sensor D that height of materials uses and control the vibratory pump M of its start-stop by sensor, electric cabinet 2 is installed on the lateral wall of funnel 1.Vibratory pump M is installed in the top, taper position in the funnel 1, and the probe of sensor D is installed in the highest spacing place of fragmentary material in the funnel 1.

Among Fig. 2, the start-stop of described sensor D control vibratory pump M is the switch that is connected with air switch S and relay K M1 in the current supply circuit of vibratory pump M; On the control loop of vibratory pump M, the coil of time relay KT and the switch serial connection of controlling by sensor D; The Time Delay Opening contact of the open contact of intermediate relay KM2 and time relay KT and the coil tandem of relay K M1, above-mentioned two sequential circuit parallel connections, the coils from parallel connection of coils of intermediate relay KM2 is on the coil of time relay KT.

Transfer continuously with many vibratory pump M of funnel 1 in order to control more piece, on described time relay KT coil and series arm, also be in series with switch by logic controller PLC control by sensor D master cock.

The people participates in the operation to vibratory pump M at any time for convenience, vibratory pump M can not work when preventing also that in a single day electric component breaks down on the control loop, on the open contact of described intermediate relay KM2 and circuit that the Time Delay Opening contact of time relay KT is connected in series, be parallel with manual control button SB.

In order to protect vibratory pump M not produce overload, thermal relay FR also is installed on power circuit, the normally closed contact of thermal relay FR is connected on the control circuit.

When sensor D detects the big strand material of funnel 1 reception above the predetermined altitude value, the closing of contact of sensor D, the coil of time relay KT and intermediate relay KM2 gets, the closing of contact of intermediate relay KM2, the Time Delay Opening contact of elapsed time relay K T, make relay K M1 coil get, the relay K M1 closing of contact on the major loop, major loop is connected the vibratory pump M work that makes, the interior bonding of obstruction funnel 1, the material of obstruction are broken up, guaranteed the normal operation of belt conveyor system; After funnel 1 mediation, the delay time of setting-up time relay K T has also arrived, and delayed contact disconnects, and vibratory pump M quits work, thereby finishes a working cycle.
