Description
Technical Field
The utility model relates to a material conveying device, in particular to a wear-resistant device for feeding of a storage bin.
Background
At present, powder is mainly conveyed into a lime bin and an active carbon bin in a pneumatic conveying mode, but particulate matters in the powder easily cause the abrasion of conveying equipment after being rubbed with a pipeline for a long time, particularly the position of a bent pipe of a feeding port, the powder directly erodes the inner wall of the bent pipe due to the sudden change of the movement direction of the powder, so the abrasion condition is serious, and the maintenance cost is greatly increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art and provide a wear-resisting device for feeding a storage bin, which has the characteristics of good wear resistance and convenient maintenance.
The technical scheme of the utility model is as follows:
the utility model provides a wear resistant device for feed bin feeding which characterized in that: the device comprises a supporting pipe which is vertically arranged and a butt joint pipe which is horizontally arranged and communicated with the supporting pipe; the right end of the butt joint pipe is connected with the pipe wall of the supporting pipe, the top end of the supporting pipe is fixedly provided with a cover plate, the bottom surface of the cover plate is provided with a buffer block extending into the inner cavity of the supporting pipe, and the buffer block is provided with a buffer surface which is obliquely arranged to meet the erosion of the powder.
The outer diameter of the supporting pipe is larger than that of the butt joint pipe.
The vertical projection surface of the butt joint pipe is positioned inside the vertical projection surface of the buffer surface.
The buffer block comprises a shell made of metal and concrete filled in the shell.
The top end of the supporting pipe is provided with a supporting flange, and the cover plate is fixed with the supporting flange through a fastening piece.
And the left end of the butt joint pipe is provided with a butt joint flange.
The top surface of the cover plate is provided with a handle.
The utility model has the beneficial effects that:
the buffer block can be disassembled, so that later maintenance is facilitated, the support pipe can also serve as a temporary observation hole after the buffer block is disassembled, and maintenance is facilitated.
Drawings
Fig. 1 is a schematic front view of the present invention.
Fig. 2 is a schematic top view of the present invention.
Fig. 3 is a schematic perspective view of the cover plate and the buffer block according to the present invention (omitting the handle).
Detailed Description
The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following examples.
As shown in figure 1, the wear-resisting device for the feeding of the storage bin comprises a supporting pipe 1, a butt joint pipe 2, a cover plate 3 and a buffer block 4.
The butt joint pipe is horizontally arranged, a butt joint flange 8 is arranged at the left end of the butt joint pipe and used for being connected with an external pneumatic conveying pipeline, and the right end of the butt joint pipe is communicated with the supporting pipe.
The stay tube is vertically arranged, the outer diameter of the stay tube is larger than that of the butt joint tube, an opening is formed in the tube wall of the stay tube, the right end of the butt joint tube is welded and fixed with the opening, the bottom end of the stay tube is communicated with a top cover inlet (usually, the stay tube is welded and fixed with the bin) of an external bin, a supporting flange 6 is arranged at the top end of the stay tube, and the cover plate is fixed with the supporting flange through a fastener 7. The fastener is a bolt and a nut.
The top surface of the cover plate is provided with a handle 9, and the buffer block is arranged on the bottom surface of the cover plate and extends into the inner cavity of the supporting tube. The buffer block is provided with a buffer surface 5 which is obliquely arranged in the supporting tube channel and used for facing the powder scouring.
The vertical projection face of the butt joint pipe is located inside the vertical projection face of the buffering face (the horizontal direction of fig. 1 is the projection direction), the width of the buffering face (the vertical direction of fig. 2) is larger than the outer diameter of the butt joint pipe, the top of the buffering face is located above the butt joint pipe, the bottom of the buffering face is located below the butt joint pipe, so that the buffering face can be guaranteed to completely block powder discharged from the butt joint pipe, the damage to the inner wall of the supporting pipe caused by direct erosion of the powder is avoided, after the powder hits the buffering face, the powder directly drops downwards, and the powder falls into a storage bin after passing through the supporting pipe. When the buffer surface is seriously worn, only the buffer block needs to be replaced. As shown in fig. 1, the central axis of the interface tube passes through the center of the buffer surface.
The buffer block includes the shell that the metal was made and fills the inside concrete in the shell, and the concrete is used for increasing the quality of buffer block, avoids the buffer block to receive the powder and takes place the vibration when assaulting. The shell is in a wedge shape with a large upper part and a small lower part, the longitudinal section of the shell is triangular, the shape of the buffer surface is rectangular or trapezoidal, and the included angle between the buffer surface and the horizontal plane is 30-60 degrees.
Preferably, the outer diameter of the butt pipe is 108mm, the outer diameter of the support pipe is 325mm, the thickness of the cover plate is 3mm, the length (vertical direction in fig. 1) of the buffer block is 270mm, and the included angle between the buffer surface and the horizontal plane is 45 degrees.
