Detailed Description
The present invention will be further explained by the following embodiments with reference to the attached drawings.
Example (b): as shown in fig. 1-2, a self-sealing internal circulation shot blasting and rust removing device for the inner wall of a large-caliber steel pipe comprises a case 1, wherein the internal space of the case 1 comprises a material throwing area, a conveying area and a material collecting area; the throwing area, the conveying area and the collecting area can be formed by isolating a partition board in the case 1;
the conveying area is provided with an upper conveying belt 21 and a lower conveying belt 22;
the material throwing area is provided with a shot blasting machine 31, the shot blasting machine 31 is used for receiving the rust removal pills conveyed by the upper conveying belt 21 and throwing out the rust removal pills, the material throwing area is provided with a material throwing port 32 capable of being in sealing fit with the inner wall of the steel pipe and a recovery port 33 arranged below the material throwing port 32, and the lower conveying belt 22 is positioned below the recovery port 33; in order to achieve a better recovery effect, the material throwing area is arranged in a V shape;
the collection area is located on the side of the conveying area and used for receiving the derusting pills recovered by the lower conveying belt 22, and a transfer mechanism 4 used for transferring the derusting pills to the upper conveying belt 21 is further arranged in the collection area.
When the rust removing device is used, the rust removing device is fed into a pipe, the material throwing port 32 is attached to the pipe wall, the steel pipe rotates slowly and advances forwards, in the advancing process of the steel pipe, an upper conveying belt 21 in the rust removing device sends rust removing pills to a feeding end of a shot blasting machine 31, the rust removing pills are thrown out by the shot blasting machine 31 and then hit on the pipe wall to remove rust on the pipe wall, then the rust removing pills fall off from a recovery port 33 under the action of self gravity and fall on a lower conveying belt 22 below, the lower conveying belt 22 conveys the rust removing pills to a material collecting area, a transfer mechanism 4 in the material collecting area transfers the rust removing pills to the upper conveying belt 21 and is conveyed to the shot blasting machine 31 again by the upper conveying belt 21 to be thrown out, therefore, the rust removing pills can be recycled in the operation process of the rust removing device, and the working efficiency is greatly improved.
Specifically, the transfer mechanism 4 includes a vertical conveying belt 41, and a material digging plate 42 disposed on the vertical conveying belt 41, the material digging plate 42 is disposed in an inclined manner with respect to the vertical conveying belt 41, and an included angle region between the material digging plate 42 and the vertical conveying belt 41 is formed as a loading region 43.
In order to attach the throwing port 32 to the pipe wall in a sealed manner, prevent rust removal pills from overflowing between the throwing port and the pipe wall and improve the safety in the operation process, the flexible attaching portion 34 is installed on the throwing port 32, the flexible attaching portion 34 is attached to the inner wall of the large-diameter steel pipe in a flexible contact manner to form a sealed shot blasting working space, and shot blasting and rust removal are completed in the space, specifically, the flexible attaching portion 34 is of a rubber structure. Because flexible laminating portion 34 is easy to appear wearing and tearing in the steel pipe rotation in-process that advances, consequently, flexible laminating portion 34 is the easy wearing and tearing spare, so, flexible laminating portion 34 releasable connection can be through connection such as joint mode, fastener connected mode on throwing material mouth 32.
When the transfer mechanism 4 conveys the rust removing pills to the upper conveying belt 21 again, the phenomenon that the rust removing pills fall off from the upper conveying belt 21 occurs because the transfer amount of the rust removing pills is too large, once the rust removing pills fall off, not only is the supply amount of the rust removing pills reduced, but also the rust removing quality of each position of the pipe wall is difficult to continuously ensure, and the fallen rust removing pills are accumulated in the conveying area for a long time, so that the operation of the upper conveying belt 21 and the lower conveying belt 22 is influenced, the operation of a rust removing device needs to be stopped periodically and is specially cleaned, the rust removing efficiency is greatly reduced, therefore, an aggregate guide part 51 which is positioned between the upper conveying belt 21 and the lower conveying belt 22 and is connected with the aggregate area is arranged outside the outlet of the aggregate area, the aggregate guide part 51 is arranged in an inclined way, and the aggregate guide part 51 guides the rust removing pills falling from the upper conveying belt 21 to, the derusting pills are timely recovered, and the working efficiency of the derusting device is further improved.
Similarly, the inlet 50 of the material collecting area is provided with a second guide part 52 which is obliquely arranged below the lower conveying belt 22, and the second guide part 52 guides the rust removing pills falling from the lower conveying belt 22 into the inlet 50 of the material collecting area in time, so that the rust removing pills are prevented from falling into the conveying area and being accumulated, and the working efficiency of the rust removing device is further improved.
Considering that the rust removing pills falling from the first guide part 51 are just in the path of the rust removing pills falling from the second guide part 52 and can influence the entering of the rust removing pills falling from the second guide part 52 into the material collecting area, for this reason, the first guide part 51 and the second guide part 52 are arranged in a staggered mode in the horizontal direction, so that the rust removing pills falling from the first guide part 51 and the rust removing pills falling from the second guide part 52 can never collide or influence each other, the rust removing pills falling from the second guide part 52 can be ensured to really and smoothly fall into the material collecting area, and the working efficiency of the rust removing device is further improved.
In this embodiment, a cleaning brush 53 and a cleaning roller 54 are also provided at the entrance 50 of the collection area in a manner opposite to the movement of the lower conveyor belt 22. Through the dual clearance of cleaning brush 53 and cleaning roller 54, will not drop and attach the rust cleaning ball of conveyer belt 22 down and clear up to the at utmost, prevent to drop at the transport zone, further promoted the work efficiency of rust cleaning device to, cleaning roller 54 rotates with the direction opposite with conveyer belt 22 down, and the clearance effect is better, and cleaning roller 54 can adopt the steel wire wheel, long service life.
The machine case 1 is also connected with a vacuum fan and a dust remover, dust generated in the shot blasting and rust removing process is cleaned in time through a dust removing device, the positions of the vacuum fan and the dust remover are determined according to actual conditions, and the vacuum fan and the dust remover can be butted to a dust removing interface of the shot blasting machine 31 through an air duct pipe to prevent dust from falling off during dust collection.
