Description
Technical Field
The utility model relates to a hopper capable of giving an alarm in stages in the transportation process of a belt conveyor to reduce the possibility that the belt conveyor cannot work due to material blockage, and belongs to the technical field of conveying equipment of the belt conveyor.
Background
The belt conveyor is an important device for conveying materials in iron and steel production enterprises, and is used for conveying ores, cokes and various materials. The belt conveyor needs to carry out relay conveying in the operation process, the upstream belt conveyor transfers materials to the downstream belt conveyor through the discharging hopper, in order to prevent massive materials and impurities in the materials from blocking the discharging hopper, the existing discharging hopper is generally provided with the anti-blocking signal device, the anti-blocking signal device can effectively detect whether the discharging hopper is blocked or not, the belt conveyor is stopped in time when the discharging hopper is blocked, and an alarm signal is sent to inform maintenance personnel to dredge the discharging hopper. Although the anti-blocking signal device can stop and alarm in time, and prevents the material overflow accident, the anti-blocking signal device can only act after the blocking happens, so that the state that the belt conveyor stops to wait for maintenance is caused, the normal material conveying is influenced, and the improvement is very necessary.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing a belt conveyor anti-blocking funnel capable of giving an alarm in stages, wherein the anti-blocking signal device of the anti-blocking funnel can send out an alarm signal at the first time to inform maintenance personnel to dredge when a blanking funnel is blocked but not completely blocked, and meanwhile, the belt conveyor keeps running, and sends out a second alarm and stops for maintenance after the blanking funnel is completely blocked, so that the aim of keeping the normal running of the belt conveyor as far as possible is fulfilled.
The technical scheme for solving the technical problems is as follows:
the utility model provides a band conveyer anti-blocking funnel that can report to the police stage by stage, its funnel comprises main funnel and overflow launder, the overflow launder is located the front portion of main funnel, the upper end of overflow launder is connected with the upper end of main funnel, the upper end of main funnel and overflow launder is connected with the rear end of upper reaches band conveyer respectively, the lower extreme of main funnel and overflow launder is relative with the conveyer belt surface of low reaches band conveyer respectively, install first putty alarm switch in the lower part of main funnel, install second putty alarm switch on the upper portion of overflow launder.
The belt conveyor anti-blocking funnel capable of giving an alarm in stages has the advantages that the blanking aperture of the main funnel is larger than that of the overflow groove, and the second blocking alarm switch is connected with the shutdown control device of the belt conveyor.
The utility model has the beneficial effects that:
the first material blocking alarm switch can give an alarm at the first time when the main hopper is blocked, and meanwhile, the overflow groove can enable materials to be continuously discharged to keep the normal operation of the belt conveyor; and under the condition that the overflow groove is blocked, the second blocking alarm switch sends a blocking alarm signal, and meanwhile, the shutdown treatment is carried out, so that the overflow accident is prevented.
The utility model has simple structure and convenient installation and maintenance, can carry out staged alarm, keeps the belt conveyor running during the alarm period, informs maintenance personnel to carry out dredging operation, eliminates the blockage fault in time, greatly reduces the parking time, reduces the accident rate, keeps the normal running of the belt conveyor as far as possible, and has obvious economic benefit.
Drawings
Fig. 1 is a schematic structural view of the present invention.
The figures are labeled as follows: the device comprises an upstream belt conveyor 1, a downstream belt conveyor 2, a main hopper 3, an overflow groove 4, a first material blocking alarm switch 5, a second material blocking alarm switch 6 and an observation hole 7.
Detailed Description
The material blockage alarm device is composed of a main hopper 3, an overflow groove 4, a first material blockage alarm switch 5 and a second material blockage alarm switch 6.
The funnel is shown to be composed of a main funnel 3 and an overflow trough 4, the overflow trough 4 is located at the front of the main funnel 3, the upper end of the overflow trough 4 is connected with the upper end of the main funnel 3, the upper ends of the main funnel 3 and the overflow trough 4 are respectively connected with the rear end of the upstream belt conveyor 1, and the lower ends of the main funnel 3 and the overflow trough 4 are respectively opposite to the conveying belt surface of the downstream belt conveyor 2.
The figure shows that the main hopper 3 has a larger discharge aperture than the overflow chute 4, and that the material of the upstream belt conveyor 1 normally falls through the main hopper 3 to the belt surface of the downstream belt conveyor 2.
The figure shows that a first material blocking alarm switch 5 is arranged at the lower part of a main hopper 3, a second material blocking alarm switch 6 is arranged at the upper part of an overflow groove 4, the second material blocking alarm switch 6 is connected with a stop control device of a belt conveyor, an observation hole 7 is positioned on the wall of the hopper above the overflow groove 4, and the material running condition in the hopper can be seen through the observation hole 7.
The working process of the utility model is as follows:
when the main hopper 3 is blocked by massive materials, impurities and the like in the materials in the operation process of the upstream belt conveyor 1, and the main hopper 3 cannot be normally discharged, a first material blocking alarm switch 5 arranged at the lower part of the main hopper 3 gives an alarm at the first time to inform maintenance personnel to dredge and timely eliminate material blocking faults; meanwhile, the materials can be continuously conveyed to the downstream belt conveyor 2 through the overflow groove 4, and the normal operation of the belt conveyor is kept.
When main funnel 3 does not get the complete mediation, if overflow launder 4 also takes place the putty, the putty leads to second putty warning switch 6 to send putty alarm signal, carries out the shut down simultaneously and handles, prevents to take place the flash accident.
The utility model can carry out staged alarm in the working process, the belt conveyor can still keep running after the first alarm, time is provided for dredging operation of maintenance personnel, the stop time is greatly reduced, the accident rate is reduced, the normal running of the belt conveyor is kept as much as possible, and the utility model has obvious economic benefit.
One embodiment of the utility model is as follows:
the length of the main funnel 3 is 1400mm, the height is 2000mm, and the width (inner diameter) is 1250 mm;
the length of the overflow groove 4 is 1000mm, the height is 1200mm, and the width (inner diameter) is 1250 mm;
the first material blockage alarm switch 5 and the second material blockage alarm switch 6 are limit switches LXP1(3SE 3).
