Description

Bulk material conveying belt cleaning device

Technical Field

The utility model belongs to the technical field of the belt feeder transportation, in particular to bulk material conveyor belt cleaning device.

Background

In the process of transporting bulk materials such as coal, ore and the like by using a belt conveyor, the powdery material at the bottom layer of a belt can be stuck on the surface of the belt due to high moisture content and material extrusion, and part of the material stuck on the surface of the belt is scattered along with the vibration of the belt and the friction of a return carrier roller in the return transportation process of the belt, so that the environment is polluted; part material that the adhesion is on the belt surface can constantly pile up all the time, can cause the wearing and tearing of the sticky tape of belt feeder, bearing roller, cylinder to a certain extent to increase, causes the trouble to shut down even, influences its normal work production.

The existing belt cleaning device mainly cleans slurry on a return belt, the slurry is in a slurry state after cleaning, although the water content is high, the viscosity is still high, and the precipitated material is easy to harden and difficult to clean and dispose. The manual cleaning at regular intervals causes the occupation of personnel and influences the beautiful appearance of the environment.

Disclosure of Invention

In order to solve the problems, the utility model aims at providing an integrated cleaning device who is located bulk material belt conveyor head funnel is applied to the sticky tape material of cleaing away the belt return stroke, adopts the complete set clean to wash, also can solve the problem that belt conveyor washs and cleaning waste water deals with, and the device can avoid containing coal, ore deposit sewage treatment, makes the material obtain make full use of, practices thrift the engineering investment.

In order to achieve the above object, the utility model adopts the following technical scheme: a bulk material conveyor belt cleaning apparatus comprising: belt feeder, funnel, sweeper, the head setting of belt feeder is in the funnel, the sweeper sets up in the return belt department that is located the belt feeder head, funnel bottom intercommunication low reaches material flow.

The sweeper is provided with a front sweeper group, a middle washing sweeper group and a rear sweeper group which are sequentially arranged along the running direction of a return belt.

The front group of cleaners comprises 1-2 cleaners which are arranged at a proper position behind a material throwing end point of a roller at the head of the belt conveyor; the middle group of flushing cleaners comprises 1-2 sets of flushing cleaners which are arranged behind the front group of cleaners; the rear group of cleaners comprises 1-2 cleaners which are arranged behind the middle group of flushing cleaners.

The top of the front group of sweepers is provided with a sticky material cleaning scraper; the middle group of flushing sweeper is provided with a gas-water mixed flushing device for flushing and cleaning excess materials, and each set of flushing device is provided with 1 row of nozzles along the width direction of the belt; and the top of the rear group of sweepers is provided with a sizing and a sewage cleaning scraper.

The belt feeder sets up belt material stream detection device in the position that is close to the head, belt material stream detection device washes the sweeper interlock with well group.

The utility model has the advantages that: after the belt conveyor finishes discharging, materials stuck on the return belt conveyor can have partial residues after passing through the front group of cleaners, the materials stuck on the adhesive tape can be cleaned by the middle group of flushing cleaners, the partial materials drop, the partial materials are softened, the back group of cleaners remove the adhesive and the sewage to the greatest extent, and the materials fall back into the head funnel and enter the conveying flow of the downstream belt conveyor through the downstream chute. The coal-containing and ore-containing sewage swept down on the return belt directly enters a downstream flow, so that the recovery and treatment of the sewage are avoided, the water content of conveyed materials is increased, and the dust falling effect is realized. The cleaning and recycling system in the form is simple and convenient to construct, low in manufacturing cost, short in construction period, convenient to operate, energy-saving and environment-friendly. The utility model discloses can combine organically with bulk cargo belt feeder such as colliery, have popularization and using value.

Detailed Description

The cleaning device for bulk material conveying belt of the present invention will be further described with reference to the accompanying drawings and embodiments.

The utility model relates to a bulk material conveyor belt cleaning device arranges leading group sweeper, well group in proper order along return stroke belt feeder direction and washes sweeper, back group sweeper in the head funnel of belt feeder. After the materials are thrown by the head of the belt conveyor, part of the materials are adhered to the belt, the front group of cleaners are used for removing the residual materials with small adhesive force on the belt, after the materials pass through the front group of cleaners, the residual materials are softened and removed by a steam-water mixture sprayed by the middle group of cleaners, and finally, the rear group of cleaners scrape off the sewage on the belt. The starting of the middle group flushing sweeper is interlocked with the belt material flow detection device, the material flow detection device is arranged at the position, close to the head, of the belt conveyor, and when the material flow detection device detects materials, a signal is sent to a control system of the flushing sweeper, and at the moment, the middle group flushing sweeper starts to work to flush the belt; when no material arrives within a period of time, the flushing sweeper stops working.

As shown in fig. 1 and 2, the front group cleaner 2, the middle group flushing cleaner 3 and the rear group cleaner 4 are arranged in the belt conveyor head hopper 1 in sequence along the running direction of the return belt. The attached material on the return belt conveyor is cleaned by the front group sweeper 2 firstly, then is washed by the high-pressure air mixture of the middle group washing sweeper 3, and finally is scraped by the rear group sweeper 4 to remove the residual attached slurry and the washing sewage attached to the return belt, and the cleaned material, slurry and sewage directly fall into the head funnel 1 and fall to the downstream belt conveyor along the inner wall of the head funnel 1 and the sliding barrel.

A belt material flow detection device LL-I/I is arranged at a position, close to the head, of the belt conveyor and is interlocked with the middle group flushing sweeper, when the material flow detection device detects materials, a signal is sent to a control system of the flushing sweeper, and the middle group flushing sweeper starts to work to flush the belt; when no material arrives within a period of time, the flushing sweeper stops working.

The utility model discloses the main facilities equipartition is put within belt feeder head funnel, has solved safety in production, the environmental impact problem that belt feeder return belt material scatter and bring along on the way, has also avoided cleaning the material that gets off and has cleaned the recovery processing problem with sewage, makes the material no longer because of return belt material scatters and the loss, and has increased the humidity of material, the certain reduction belt feeder raise dust problem. The example proves the advantages of the utility model structure, and has great popularization and application values.
