Abstract

The utility model relates to a single-pipe spiral conveyor without a reduction gearbox. The single-pipe spiral conveyor comprises a frequency-conversion control cabinet, a spiral shaft and a conveyor body, wherein the spiral shaft is transversely arranged inside the conveyor body, the two outer ends of the spiral shaft are connected with a driving shaft assembly unit and a driven shaft assembly unit respectively, the upper surface and the lower surface of the conveyor body are provided with a material inlet and a material outlet respectively, the driving shaft assembly unit is connected with an output shaft of a permanent-magnet synchronous motor through a coupler, and the frequency-conversion control cabinet is arranged outside the conveyor body. The single-pipe spiral conveyor has the advantages of being small in size, reducing the failure rate and the like due to the fact that the permanent-magnet synchronous motor replaces a common alternating current motor and the reduction gearbox. The permanent-magnet synchronous motor is controlled in a permanent-conversion mode to achieve large starting torque and the torque protecting function, particulate material can be conveyed easily, and the spiral shaft can be prevented from being broken or deforming. Due to frequency-conversion control, conveying efficiency can be greatly improved, and the motor is protected. Operation modes of the conveyor can be switched, high-torque starting is guaranteed, and the motor and the spiral shaft will not be damaged.

Description

A kind of without the box single-pipe screw conveyer that slows down

Technical field

The utility model relates to a kind of continuous conveying equipment, relates in particular to a kind of box single-pipe screw conveyer of nothing deceleration that is applicable to the fields such as metallurgy, building materials, chemical industry, grain and machine up.

Background technology

At present, in the industries such as metallurgy, building materials, it is general that to adopt the simple helix conveyer to carry out mass transport very general, common way is to adopt the mode of common electric machine acceleration and deceleration case to carry out, its principle is that the helicallobe of rotation is passed material and carries out the conveyor screw conveying, and the power that material is not rotated together with the conveyor screw blade is material own wt and the conveyor screw body friction drag to material; The screw shaft of conveyor screw has thrust bearing with the axial counter-force to spiral with material in the terminal of material movement direction.But, because there are the problems such as dust is many, environment is severe in industry itself, cause existing simple helix conveyer to exist following defect: while 1. various powders being carried, often can cause drop-gear box to be covered by powder, cause the drop-gear box fault, affect the efficiency of mass transport; While 2. being carried for granular material, spiral often can occur and stop up and cause the motor torque overload, finally cause the motor tripping operation; 3. because the simple helix size is long, without any protection, the force start motor causes screw shaft to fracture or is out of shape in meeting usually.Therefore, for above aspect, need to reasonably improve prior art.

The utility model content

For above defect, the utility model provides a kind of guarantees that the simple helix device volume is less and efficiency is higher, be convenient to assembling, convertible operational mode, be conducive to guarantee the normal operation of equipment without the box single-pipe screw conveyer that slows down, to solve many deficiencies of prior art.

For achieving the above object, the utility model is by the following technical solutions:

A kind of without the box single-pipe screw conveyer that slows down, comprise frequency-conversion control cabinet, screw shaft and body, described internal body horizontally set screw shaft, the outside two ends of described screw shaft connect respectively imput shaft assembly unit, driven shaft assembly unit, upper and lower two surfaces of body are wherein offered respectively an inlet point, a discharging opening successively, imput shaft assembly unit wherein joins by coupler and permasyn morot output shaft, and described engine body exterior is installed frequency-conversion control cabinet.

Also can select, the axle center of the axle center of described screw shaft and permasyn morot output shaft is on the same straight line; Described discharging opening is arranged at the body surface that is positioned at driven shaft assembly unit one side.

Beneficial effect without the box single-pipe screw conveyer that slows down described in the utility model is:

(1) substitute common alternating current dynamo and drop-gear box by permagnetic synchronous motor is set, there is the advantages such as volume is little, fault rate reduction;

(2) the variable frequency control magneto-electric machine has detent torque greatly and the torque defencive function, and easily delivery of particulate material, also can prevent that screw shaft from fractureing or being out of shape;

(3) variable frequency control can improve transport efficiency greatly, the protection motor;

(4) can be widely used in the departments such as chemical industry, building materials, metallurgy, grain; when conveying powdered, graininess and piece material; can be in the situation that floor area requires harsh, the severe failure-free operation of environment; when particulate matter is stuck; this conveyer switches to the torque operational mode; guarantee high torque (HT) to start and do not damage motor and screw shaft, having protected the normal operation of equipment.

The accompanying drawing explanation

Below with reference to the accompanying drawings the utility model is described in further detail.

Fig. 1 is the described structural representation without the box single-pipe screw conveyer that slows down of the utility model embodiment.

In figure:

1, frequency-conversion control cabinet; 2, permasyn morot; 3, coupler; 4, imput shaft assembly unit; 5, inlet point; 6, screw shaft; 7, body; 8, discharging opening; 9, driven shaft assembly unit.

The specific embodiment

As shown in Figure 1, the utility model embodiment is described without the box single-pipe screw conveyer that slows down, comprise frequency-conversion control cabinet 1, screw shaft 6 and body 7, described body 7 inside center position horizontally set screw shafts 6, the outside two ends of described screw shaft 6 connect respectively imput shaft assembly unit 4, driven shaft assembly unit 9, on body 7 wherein, an inlet point 5 is offered respectively on lower two surfaces successively, a discharging opening 8, imput shaft assembly unit 4 wherein joins by coupler 3 and permasyn morot 2 output shafts, the outside frequency-conversion control cabinet 1 of installing of described body 7, thus, this machine is divided into to three parts, by imput shaft assembly unit 4, screw shaft 6, body 7, the conveyor screw body that driven shaft assembly unit 9 forms, the in-out apparatus formed by charging and discharging and by frequency-conversion control cabinet 1, permasyn morot 2, the actuating device that coupler 3 forms.During work, particulate dust or granule materials enter from inlet point 5, in body 7 along with the action of actuating device, the discharging opening 8 that progressively is transported to tail end by screw shaft 6 directions is discharged, permasyn morot 2 is wherein controlled by frequency-conversion control cabinet 1, magneto-electric machine has the characteristics of low speed, high torque (HT), can replace drop-gear box, thereby guarantees that the simple helix device volume is less, efficiency is higher; The screw shaft body only needs the assembling of dismounting imput shaft, driven shaft assembling to get final product in replacing, convenient and practical; During normal mass transport, frequency-conversion control cabinet 1 control can be switched to speed control method and start permasyn morot 2, and when material, when housing is stuck, variable frequency control 1 cabinet control switches to the torque mode and starts permasyn morot 2.

Above embodiment is the more preferably specific embodiment a kind of of the utility model, and the common variation that those skilled in the art carry out in the technical program scope and replacing should be included in protection domain of the present utility model.
