Abstract

The utility model discloses a pipe type screw conveyor, comprising an electric motor, a coupling, a speed reducer, a head bearing device, a tail bearing device, a conveying pipe, a supporting pipe, ahelicoid, a feed port and a discharge port arranged on the conveying pipe, wherein the helicoid is welded by a short pipe, a helical blade and a seamless steel pipe. There are three seamless steel pipes which are distributed evenly and penetrated on the proper radius on the spiral surface circumference and parallel to the axis and has the equal length with the helicoid. Three rollers coaxially with the seamless steel pipe are distributed evenly on the middle circumference of the supporting pipe. The inner hole and the connection shaft are in clearance fit. The excircle and the supporting pipeinner wall are contacted in a rolling way. The utility model substitutes three rollers for the hanging bearing, wherein the rollers and the pipe inner wall are contacted in the rolling way, thus, theroller is not easy to damage and is unnecessary for lubrication, thus decreasing the maintenance work capacity, reducing the maintenance cost and prolonging the service life. The conveying pipe is connected with the supporting pipe with a flange, thus having good hermeticity, particularly suitable for conveying the powdery material.

Description

A kind of tube-type spiral conveyer

Technical field

The utility model relates to a kind of conveyer of horizontal feed granular material, is specifically related to a kind of tube-type spiral conveyer.

Background technology

The present level conveyor screw be with the helicallobe sequential welding on tubular axis, form the conveyor screw of certain-length, connect with " insert shaft type " or " flange form " between conveyor screw and the conveyor screw.When helical feed material distance surpasses 3 meters, produce buckling phenomenon in order to prevent screw shaft, in the junction suspension bearing is set.Suspension bearing has increased the resistance material area, influences the raising of traffic capacity, again owing in dust atmosphere, work, the suspension bearing sealing and lubricated be an insoluble difficult problem always, and change time-consumingly, influence normal operation; The conveyor screw hopper is a U-shaped again, is covered with cover plate above, and the place, slit often has dust to overflow.On December 27th, 2006, disclosed application number was " a kind of tube-type spiral conveyer " patent of invention specification sheets of 200610051978.6, owing to do not have bearing set in the middle of the delivered length, can only be applied to short range need tilt to install or vertically arranged occasion.

Summary of the invention

The purpose of this utility model is to provide a kind of horizontal feed granular material that is suitable for, the tube-type spiral conveyer of simple in structure, the good airproof performance of cancellation suspension bearing.

To achieve these goals, the technical solution adopted in the utility model is: a kind of tube-type spiral conveyer, comprise motor, coupler, reductor, the head bearings device, the tail bearing device, delivery pipe, support tube, inlet point on conveyor screw and the delivery pipe and discharging opening, it is characterized in that conveyor screw is by short tube, helicallobe, solid drawn pipe is welded, solid drawn pipe is three, the uniform suitable radius that is arranged on the helical surface circumference, and parallel to the axis, and it is isometric with conveyor screw, uniform three rollers coaxial on the support tube intermediate circumference with solid drawn pipe, endoporus and adapter shaft free-running fit, cylindrical and support tube inwall are rolled and are joined.

Center, conveyor screw two ends is provided with the short tube that length is slightly larger than a pitch, and short tube matches with head axle, tween drive shaft, tailing axle respectively, and fastening with bearing pin.

The center upper portion of support tube has square or circular peep hole, and the top in hole is covered with inspection door.

The beneficial effects of the utility model are, because some helicallobes are coupled together by three solid drawn pipes, and tubular axis in the middle of the cancellation, thereby alleviated conveyor screw weight, saved material; Replace three rollers and the tube wall rolling touch that is distributed on the helical surface circumference owing to cancelled suspension bearing again, roller is not fragile, need not lubricate, and has alleviated maintenance load, has reduced maintenance cost, prolonged period of service; Because delivery pipe and support tube are tubulose, connect with flange between the pipe again, good airproof performance is particularly suitable for conveying powder material.
