Background

The pipe belt machine (tubular belt conveyor) is a conveying tool for conveying materials in a closed mode, is widely applied to the fields of metallurgy, mines, ports and the like, which need to convey bulk materials, and enables the materials to be completely sealed by adhesive tapes and not to leak, so that lump materials, powder materials, toxic materials and dust materials are conveyed without causing environmental pollution, the conveying belt can be bent in any direction, and when the conveying direction changes sharply, a transfer point is not needed, and the energy-saving and environment-friendly requirements can be met while the system efficiency is greatly improved.

In alumina production, a pipe belt machine is used for conveying semi-dry red mud or other materials. In the practical application process, the red mud filter press is fed intermittently, the feeding is uneven and even intermittent, the uniformity is only 50-60% (the belt is fed continuously for 10 seconds and then empty for 10 seconds), when no material is fed, the length of a few meters or more than ten meters is not fed, sometimes two or more than two red mud filter presses are simultaneously discharged in an overlapping mode, or when the front flat belt accumulated material suddenly collapses, the phenomenon of pipe expansion is caused when the material volume exceeds the maximum amount which can be accommodated by the tubular belt, even pipe twisting and pipe stacking accidents are caused, the treatment is carried out for at least ten hours or even days, a large amount of manpower and material resources are consumed, and the smooth production is seriously influenced. Therefore, it is imperative to find a feasible refining anti-expansion pipe technology. The utility model provides a method for detecting the pipe diameter of a tail pipe belt of a pipe belt machine by using an arc-shaped frame, when the pipe diameter is increased to a certain degree, the arc-shaped frame is knocked over by the pipe belt, and the arc-shaped frame drives a vertical rod to rotate and triggers a travel switch, so that a pipe belt machine controller outputs a stop signal, and further expansion of faults is prevented. This patent solves the problem of tube expansion by timely stopping, but the risk of damage to the belt drive still exists due to the long tubular belt and even the full load start after climbing and stopping.

The technical scheme adopted by the utility model is as follows: the utility model provides a pipe belting is prevented expanding by pipe belting machine refining, installs in the pan feeding section of pipe belting machine, including the buffer tank, the top of conveyer belt of pipe belting machine is located to the buffer tank, and the buffer tank passes through the mount to be fixed in the frame of pipe belting machine, and the buffer tank's material end and bottom opening that caters for set up in the buffer tank keeps off the material regulating plate, keeps off material regulating plate both sides sliding connection at the two inboards of buffer tank, keeps off material regulating plate top and buffer tank roof to have the interval.

As the preference of this technical scheme, keep off material regulating plate set up the polylith, set gradually along the material direction of delivery.

As the preference of this technical scheme, keep off material regulating plate both sides sliding connection is at two inboards of buffer tank and means, keeps off both sides of material regulating plate and buffer tank both sides all are provided with the screw hole, keeps off material regulating plate and buffer tank and passes through the bolt and insert the screw hole and realize connecting.

Preferably, the width of the buffer box is smaller than the width of the conveying belt of the pipe belt machine.

As the preference of this technical scheme, keep off the bottom of material regulating plate for with the corresponding arc of conveyer belt.

By adopting the structure, compared with the prior art, the tube expanding prevention device for the tube belt machine material refining can buffer redundant materials, effectively prevent tube expanding, tube twisting and tube stacking accidents of the tube belt machine, ensure smooth operation of the tube belt machine, improve working efficiency and have remarkable economic benefits.

Detailed Description

The present utility model will be described in detail with reference to the accompanying drawings and examples.

As shown in fig. 1 and 2, the utility model provides a tube band machine material-homogenizing tube-expanding-preventing device which is arranged on a material feeding section of a tube band machine 1, namely a flat belt section in front of a tube, and comprises a buffer box 2, wherein the buffer box 2 is arranged above a conveying belt of the tube band machine 1, the buffer box 2 is fixed on a frame of the tube band machine 1 through a fixing frame 3, a material-facing end and a bottom end of the buffer box 2 are opened, a material blocking adjusting plate 4 is arranged in the buffer box 2, two sides of the material blocking adjusting plate 4 are slidably connected on two inner sides of the buffer box 2, and the top end of the material blocking adjusting plate 4 and a top plate of the buffer box 2 are spaced.

When the utility model is implemented, the size of the buffer tank 2 is set according to the requirement, so that the volume is ensured to be larger than the excessive quantity generated by uneven materials. The width of the buffer box 2 is smaller than that of the conveyer belt of the pipe belt machine 1, and the bottom end of the material blocking adjusting plate 4 is arc-shaped corresponding to the conveyer belt. In this embodiment, the buffer tank 2 may have a length of 1.5-4 m, and the width of the conveyor belt of the pipe belt machine 1 is 1.2 m, and the width of the buffer tank 2 is 1 m, and the height is 1.5-4 m. The mount 3 can be the bracing piece of connection at buffer tank 2 outer wall, and the bracing piece is fixed in the frame of piping machine 1, keeps off material regulating plate 4 and sets up the polylith, sets gradually along material direction of delivery, keeps off material regulating plate 4's both sides and buffer tank 2's both sides all are provided with the screw hole, keeps off material regulating plate 4 and buffer tank 2 and inserts the screw hole through the bolt and realize connecting, can realize the regulation that keeps off material regulating plate 4 different positions through the screw hole of different positions.
