Description

Pipe rust remover

The utility model belongs to a kind of mechanical derusting device.Specifically, it relates to a kind of device of pipe (as straight heat exchanger tube) two ends appearance rust cleaning.

Because making the requirement of welding quality, need eliminate rust in the two ends of some pipes.As heat exchanger manufacturing firm, in the process of making heat exchanger, before heat exchanger tube penetrates tube sheet, must eliminate rust at exchange heat pipe two ends.Each producer's derusting method is different at present, but is not that hand cleaning is exactly the semi automatic machine rust cleaning.Its frame of rust remover that provides as the ZL93240291.7 patent is made of two frameworks, its connecting part is the two and half gardens ring that can rotate around the axis, all there is an air motor both sides of upper rack half garden ring, be equipped with a wire brush wheel under the motor, need the pipe fitting of rust cleaning just to be stuck in the ring of garden, be evenly equipped with the pillar that three screws are adjusted on the ring wall of garden, to block toward pipe fitting.Therefore this rust remover can not continuous operation, can only a pipe fitting have removed to refill one after becoming rusty, and eliminates rust behind the chucking again.And the rust remover that the ZL92242331.8 patent provides is suitable for the rust cleaning of whole pipe fitting, and structure is complicated, also depression bar must be reduced before rust cleaning, could eliminate rust tube grip, these derusting method labour intensity are relatively large, and rust cleaning speed is also slower, and efficient is lower.

A kind of pipe rust remover that the utility model provides, it adopts continuous self-feeding and rust cleaning to replace manual operations fully.

The utility model is made up of the delivery wheel of motor, wire brush wheel, pinch roller, chute, transmission axle, band groove and frame etc., the delivery wheel of several band grooves is installed on the transmission axle, under the drive of motor, rotate, the chute that has gradient is installed in the opening direction of groove, respectively there is an inverted L shape support top, frame both sides, platform that can rotate of last installation has wire brush wheel, the motor of rust cleaning on the platform, on the other small rack of platform pinch roller is housed.

Wire brush wheel and pinch roller are added with containment envelope on the inverted L shape support on same axis.

Utilize above-mentioned rust remover just the iron rust at pipe two ends can not removed by hand fully, the rust cleaning quality is good, can be to diameter difference, straight tube different in size rust cleaning, and also apparatus structure is simple, easy to operate, reduced investment, efficient height.

Fig. 2 is the cutaway view along the A-A line among Fig. 1.

Below in conjunction with accompanying drawing the utility model is described in further detail:

This pipe rust remover is by pipe automatic transport and pipe rust cleaning two parts.These two parts all are installed on the frame, can guarantee the stable of each parts relative position like this, and the length of frame can be regulated according to the length of pipe.

Pipe automatic transport part is made up of the chute 11 of band gradient, delivery wheel 6, pipe transmission axle 3 and the motor 5 of band groove.The delivery wheel 6 of four band grooves is installed on the pipe transmission axle 3, and its groove is arranged in a line, and the pipe transmission axle is placed on the frame 4, and the latter half of frame can be made the mountain font, to guarantee the rigidity of pipe transmission axle.The opening direction of groove is equipped with the chute 11 of band gradient, and motor 5 just is placed in frame lower, drives pipe transmission axle 3 and rotates.The big I of groove on the delivery wheel is decided according to tube outer diameter, and bottom portion of groove can be adorned bearing and also can not install, and its effect is the friction that reduces pipe and groove.

The rust cleaning part is made up of the parts such as support 1, wire brush wheel 10, pinch roller 8 and motor 9 of inverted L shape, and they are installed in the top of frame 4 both sides.In the both sides on frame 4 tops L bracket 1 is installed respectively, one of them can move laterally by slide rail, so that need rust cleaning pipe length is finely tuned.A platform 2 that can rotate respectively is housed on the support, one end of platform is to link to each other with support with caging bolt by spring 13, motor 9 and scaling brush wheel 10 is housed on the platform, motor 9 can be installed in wire brush wheel 10 above, drive scaling brush wheel high speed rotating, the angle of adjusting platform 2 can make scaling brush wheel 10 contact and produce friction with the pipe 7 that needs to eliminate rust, and is added with protective cover 15 on the inverted L shape support, dust from flying when preventing to eliminate rust.In order to make pipe can reach the purpose of whole circle rust cleaning, designed a small rack 14 on platform 2 sides, on have pinch roller 8, by spring lever pinch roller is pressed on the pipe, friction by rubber on the pinch roller and pipe, drive pipe rotation at a slow speed, pinch roller 8 must be on same axis with scaling brush wheel 10, and the rotation of pinch roller transmits after by motor 5 speed changes.This rust remover course of work is as follows:

Need the pipe of rust cleaning to put into the groove that chute 11 backs just roll into delivery wheel 6 automatically, the pipe transmission axle slowly rotates under motor 5 drives, and at this moment the pipe 7 in the groove is brought under the rust cleaning wire wheel and eliminates rust also along with delivery wheel moves together.The angle of adjusting platform 2 makes rust cleaning wire wheel 10 contact the generation friction with the pipe that need eliminate rust and the rust on the pipe can be removed, spring lever is pressed in pinch roller on the pipe, the rotation of pinch roller is transmitted after by motor 5 speed changes and, driving when it rotates needs the rotation at a slow speed of rust cleaning pipe, thereby reaches the purpose of whole circle rust cleaning.Pipe after the rust cleaning continues with the delivery wheel motion, and when delivery wheel forwarded certain angle to, pipe broke away from delivery wheel 8 voluntarily and rolls into next procedure.Causing this rust cleaning work is all over.

Claims (3)

1. pipe rust remover, delivery wheel and frame by motor, wire brush wheel, pinch roller, chute, transmission axle, band groove are formed, it is characterized in that: several groove delivery wheels are installed on the transmission axle, under the drive of motor, rotate, the chute that has gradient is installed in the opening direction of groove delivery wheel, one the L bracket of falling is respectively arranged above the frame both sides, platform that can rotate of last installation, scaling brush wheel, motor are arranged on the platform, on the small rack on platform side pinch roller is housed.

2. pipe rust remover according to claim 1 is characterized in that: wire brush wheel and pinch roller are on same axis.
