Description

Conveying belt device driven by linear motor of circulating line body

Technical Field

The invention relates to the field of mine transportation equipment, in particular to a conveyor belt type conveying device driven by a linear motor of a circulating line body.

Background

In mine conveyor installations, the capacity and efficiency of the transport is very important. It is composed of a linear motor with a circulating line body, a conveying belt and a rotary aligning rolling mechanism. The belt conveyor is one of the most important bulk material transportation equipment in the world at present, and is widely applied to various industries of national economy such as coal, chemical industry, logistics, electric power, building materials, ports and the like. In the operation process, the carrier roller and the conveyer belt are in extrusion contact and are subjected to the action of the depression resistance and the friction force of the conveyer belt, and the carrier roller rotates along with the conveyer belt and needs to overcome the rotation resistance of the carrier roller. Because the belt conveyor typically has a relatively long body with numerous idlers, the energy consumption associated with idlers can account for approximately 70% of the total energy consumption of the entire conveyor system. The material supporting mode leads the belt conveyor to consume a large amount of energy in the operation process, the common belt conveyor pulls the conveying belt to realize the continuous conveying of the material by the friction force of the driving roller, the material and the load of the conveying belt are supported by the carrier roller, the common belt conveyor adopts the carrier roller to support the conveying belt and the material, the mechanical abrasion is serious, and the energy consumption is large. In order to reduce the energy consumption and the resource utilization rate, the invention provides the conveyor belt device driven by the linear motor with the circulating line.

Disclosure of Invention

The invention aims to provide a circulating linear motor conveyor belt device with high energy utilization rate. The linear motor with the circulating line body is characterized in that a primary stage and a secondary stage fixed at the edge of the conveying belt move together in a single direction when the power is on. Has the advantages of small volume and the like.

The invention adopts the following technical scheme for realizing the purpose:

a conveying belt device driven by a linear motor of a circulating line body comprises a rotary aligning carrier roller, a conveying belt, a roller, a return carrier roller and the linear motor of the circulating line body, wherein the linear motor of the circulating line body is connected with a fixed secondary of the conveying belt through a primary stage, is connected with a power supply, is fixed at the primary stage, moves at the secondary stage, and directly drives the conveying belt to move. The energy loss of the motor driving the roller driving the conveying belt is reduced.

Preferably, in the conveyor belt device for the linear motor with the circulating line body, the conveyor belt is fixed with the secondary, the primary is arranged on the linear motor, and the electrified secondary moves linearly to drive the conveyor belt;

preferably, the conveying belt device for the linear motor with the circulating line body is additionally provided with the rotary aligning carrier roller device, so that the conveying belt device not only can support objects, but also has a function of adjusting the deviation condition;

preferably, the conveyor belt device for the linear motor with the circulating line body is characterized in that the conveyor belt arranged on the cylinder body can drive the conveyor belt to move and can prevent deviation;

has the advantages that:

1. the power is supplied by the linear motor with the circulating line body, so that the utilization rate is high;

2. the utilization rate is greatly improved by the combined motion of the primary of the linear motor with the circulating line and the secondary fixed on the conveying belt;

3. simple structure, installation and maintenance are convenient.

The specific implementation mode is as follows:

the invention is further illustrated by the following specific examples.

A conveyor belt device of a linear motor of a circulating line body is used for a device for conveying in a mine, and comprises a conveyor belt 1 and a linear motor of the circulating line body 2, wherein a fixed secondary 1 on the conveyor belt is connected together through primary electrification on the linear motor of the circulating line body, and after the electrification, the fixed primary of the linear motor of the circulating line body and the fixed secondary on the conveyor belt are combined to drive the conveyor belt to move forwards.

The carrier rollers are used for supporting the conveying belt, so that the suspension degree of the conveying belt does not exceed the technical requirement, and the smooth running of the conveying belt is ensured. The carrier roller is installed on the frame, and the conveyer belt is laid on the carrier roller, and in order to reduce the resistance of conveyer belt operation, a rolling bearing is installed in the carrier roller.

When the conveyer belt is in operation, the phenomenon of deviation can be produced because material is eccentrically piled up, the frame is out of shape, the bearing roller is damaged, etc. In order to prevent the deviation of the conveying belt. Here, a rotary aligning idler is used.
