The processing is carried out in time, the occurrence of serious material blocking is avoided, the equipment damage is avoided, and meanwhile, the production efficiency is also improved. The arrangement of the collecting chute enables the flash of the chute to return to the system in time, thereby not only ensuring clean production, but also being beneficial to saving.

Description

External belt feeder chute putty detection device

Technical Field

The utility model relates to a technical field is carried to the material, especially belongs to a device suitable for carry out chute material stifled condition detection to belt feeder system chute position.

Background

The ore system is apart from long, the design flow is complicated, adopts the multistage belt transportation, and two sections belt junctions need to be connected with the chute, when the goods viscidity is big or the mass flow appears, the easy putty in the chute, if the putty situation takes place, the goods can fill up the chute in several seconds to pile up rapidly, the compaction, parts such as belt, bearing roller support, sweeper to the chute below cause serious damage, subsequent production resumes need consume plenty of time, manpower and material resources. The blockage detection is the key for guaranteeing the safe operation of the system, the chute blockage condition can be timely and accurately detected, the unnecessary damage of equipment can be effectively avoided, and the production efficiency is improved. Former putty switch installs inside the chute, can not effectively detect the material stifled, and the wrong report is alert appears easily, has following shortcoming:

1. the cargo flow of the ore system is about 3500 tons/hour, the speed is 5.15m/s, and the materials collide at high speed in the chute and easily collide a material blocking switch arranged in the chute to cause malfunction and shutdown, so that the production is influenced; meanwhile, the sudden stop easily causes the blockage of the upstream belt conveyor, consumes manpower and damages equipment.

2. The raw material blocking switch is arranged at the rear cross beam of the material throwing plate, and due to the fact that the material blocking switch (mercury switch) is connected with the trough main body, when the vibration force of the vibrator is large, the mercury switch is caused to malfunction frequently, and due to long-term vibration, the service life of the mercury switch is greatly reduced.

3. The goods that the ore system carried are of many kinds, and when carrying viscidity goods, "wall built-up" phenomenon appears easily at the chute inner wall, and when the putty condition really appears, material stifled switch can not detect on the contrary, can not in time shut down, has the potential safety hazard.

4. The putty switch is installed in the chute, when damaging the maintenance, needs personnel to get into the chute inside, and it is long when the maintenance is used, and has certain potential safety hazard.

Disclosure of Invention

An object of the utility model is to provide an external belt feeder chute putty detection device promptly to reach simple structure, can in time detect the purpose of the interior putty condition of chute.

The utility model provides an external belt feeder chute putty detection device, a serial communication port, including flash tray, off tracking switch, seted up the flash mouth on the non-impact face of chute feed end, the outer tip of the one end welding of flash tray at the trigger arm of off tracking switch, the below of flash mouth is arranged in to the other end of flash tray and with chute outer wall contactless, the off tracking switch install on chute periphery steel construction.

Furthermore, a collection chute is arranged at the bottom of the corresponding flash tray, the collection chute is fixed on the outer wall of the chute, the opening area of the collection chute is larger than the covering area of the flash tray above the collection chute, and the collection chute is connected back to the belt conveyor system.

The utility model provides an external belt feeder chute putty detection device compares with the stifled switch of original material, the utility model has the advantages of it is following:

1. the device is arranged outside the chute, so that the condition of material impact in the chute is avoided, and misoperation and shutdown can not be caused. Meanwhile, the influence of the vibrator on the switch is reduced, and the problem of misoperation of the original mercury switch caused by vibration of the vibrator is avoided.

2. The chute blockage situation can be accurately detected, timely treatment is carried out, the serious blockage situation is avoided, and the production efficiency is improved while the equipment damage is avoided.

3. Through the installation mode of the external chute putty switch, later maintenance and repair are more convenient.

4. The arrangement of the collecting chute enables the flash of the chute to return to the system in time, thereby not only ensuring clean production, but also being beneficial to saving.

Drawings

The accompanying drawings partially disclose embodiments of the present invention, in which,

fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

As shown in fig. 1, the utility model provides an external belt feeder chute putty detection device, including flash tray 2, off tracking switch 3, the flash tray adopts the iron tray, has seted up flash mouth 1 on the non-impact surface of 5 feed ends of chute, and the one end welding of flash tray is at the outer tip of the trigger arm of off tracking switch, and the below of flash mouth and with chute outer wall contactless are arranged in to the other end of flash tray, and the off tracking switch can adopt stay cord switch or tear the switch, for example: a belt pull switch of T3Z 068-22yr, a pull switch of GYLS-II-KC-9C, a pull switch of LHPEw-13/2-B, or a tear switch of PLR 50-2D-G. The deviation switch is arranged on a chute periphery steel structure 4. In this embodiment, the off tracking switch is installed below the head roller of the belt conveyor system through a support and is located 25cm away from the vertical edge of the trough. This device is in concrete application, the off tracking switch circuit inserts in the control system of belt feeder to act on the equipment and shut down the return circuit, like this, when the phenomenon of putty takes place in the chute, the chute passes through the outside flash of discharge opening, and fall into on the flash tray, along with the increase of material on the flash tray, the flash tray receives the trigger arm that the action of gravity acted on the off tracking switch, it produces switching signal to be its action, at this moment, belt feeder control system acts on the equipment and shuts down the return circuit, the system is shut down, after the staff in time handled the putty trouble problem, resume production.

In addition, the bottom that corresponds the flash tray still is provided with collects chute 6, collect the chute and fix on the chute outer wall, and the open area of collecting the chute is greater than the area of coverage of the flash tray of its top, above-mentioned collect the chute and connect back to belt feeder conveying system, through the setting of collecting the chute, make the outer flash of chute can in time get back to belt feeder conveying system, prevent that the outer flash of chute from falling on equipment, subaerial and producing secondary pollution, when guaranteeing cleaner production like this, still be favorable to the saving.
