The cleaning device starts to work, the cleaning plug 13 moves from the end of the conveying wheel 14 to the end of the conveying wheel 15 on the starting point, and in the process that the cleaning plug 13 is pulled by the traction rope 17 to advance, the residual concrete on the inner wall of the heating conveying pipe 2 can be scraped to the output port 202 of the heating conveying pipe 2 and scraped out of the heating conveying pipe 2. After the cleaning plug 13 reaches the output port 202, the stepping motor rotates reversely to enable the cleaning plug 13 to move upwards to the end of the conveying wheel 14, and the cleaning plug 13 is reset to the original position, so that the whole operation of the microwave heating concrete equipment is finished.
Example two
On the basis of the first embodiment, the embodiment provides an improved cleaning plug.
Because of the characteristics of concrete, after long-time operation, a small portion of concrete may be condensed on the inner wall of the heating conveying pipe 2 and is inconvenient to clean, even if the cleaning plug 13 can clean the inner wall of the heating conveying pipe 2 back and forth, a sufficient cleaning effect cannot be ensured, and moreover, the cleaning plug 13 cannot pass due to blockage, so that faults are caused.
In order to solve the possible fault hidden trouble, the present embodiment proposes a setting that can also rotate around the transverse axis direction of the cleaning plug 13 in the moving process of the cleaning plug 13, so that not only can the intractable concrete be avoided from being cleaned, but also the cleaning efficiency can be improved, and the normal operation of the equipment is ensured. Specifically, as shown in fig. 6, a fixed long rod 18 parallel to the traction rope 17 is further disposed on the transmission inclined plane 101, the fixed long rod 18 penetrates through the center point of the cleaning plug 13, and the cleaning plug 13 can still rotate relative to the fixed long rod 18 in the transverse axis direction. The outer wall of the fixed long rod 18 and the through hole wall of the cleaning plug 13 are provided with mutually matched thread structures, and the cleaning plug 13 can be influenced by threads to rotate in the process of moving towards two ends. The two end faces of the ball body of the cleaning plug 13 are embedded with rotary thin plates 19 through Kong Zhouyan, the rotary thin plates 19 are rotatably connected with the cleaning plug 13, and the center of the rotary thin plates 19 can be penetrated by a fixed long rod 18. The rotary sheet 19 is provided with traction hooks 20, and the traction ropes 17 are respectively connected with the traction hooks 20 at two ends of the cleaning plug 13. In operation, the traction rope 17 advances in any direction, the traction rope 17 pulls the cleaning plug 13 through the traction hook 20, and the cleaning plug 13 is pulled to advance by tension force and rotates. When the cleaning plug 13 rotates, the rotating sheet 19 rotates relative to the cleaning plug 13 due to the continuous pulling force of the pulling rope 17, so that the rotating sheet 19 always keeps a relatively static state relative to the fixed long rod 18. After the cleaning plug 13 enters the heating transport pipe 2, the cleaning plug 13 is rotated in the lateral axis direction. When rotating, not only can scrape the clearance effect of cleaning up to heating conveyer pipe 2 inner wall, has further improved clean effect, still can clear up the concrete that adheres to on the fixed stock 18, release the sphere of screw thread gap through clean stopper 13 with the concrete, drop in heating conveyer pipe 2 to take it out heating conveyer pipe 2 through clean stopper 13 thereby accomplish the clearance.
Preferably, the cleaning plug 13 is provided with a raised particle structure or a porous structure, so that refractory concrete agglomerations can be cleaned more efficiently, and the cleaning effect and the normal operation of equipment are ensured.
By using the cleaning plug structure provided by the embodiment, development and material cost are not increased, additional power consumption is not increased, and cleaning efficiency of the inner wall of the heating conveying pipe 2 can be further improved through rotation of the cleaning plug 13.
Example III
On the basis of the second embodiment, this embodiment proposes a cleaning plug with a brushing member.
The heating transport pipe 2 may be collided with fine stones in the concrete during long-term use, resulting in abrasion of the inner wall of the heating transport pipe 2. To ensure the durability and the use effect of the heating delivery pipe 2, operators typically brush the inner wall of the pipe with an anti-rust coating or other protective paint to cover and protect the damaged area of the inner wall of the pipe by chemical effects. However, the heating conveying pipe 2 has a longer diameter, so that the smearing and nursing work is inconvenient, and meanwhile, the manual operation procedures are increased, so that the working strength is increased.
Therefore, the inner wall of the heating conveying pipe 2 can be simultaneously coated with the protective coating in the cleaning process of the cleaning plug 13 on the inner wall of the heating conveying pipe 2, so as to achieve the required effect. Specifically, a brushing member 21 is disposed between the through hole at either end of the cleaning plug 13 and the side surface apex, and the brushing member 21 is detachably connected to the solid structure of the cleaning plug 13 through the cleaning material on the surface layer of the cleaning plug 13. As shown in fig. 7, the brushing part 21 comprises a spring 22, a brush head 23 and a protection plate 24, wherein the protection plate 24 is in a cambered surface wrapping structure, the brush head 23 is arranged in the concave surface of the protection plate 24, and the brush head 23 is connected with the cleaning plug 13 through the spring 22. The concave surface of the protection plate 24 faces the fixed long rod 18, the top end of the brush head 23 is inclined toward the pipe wall of the heating conveying pipe 2, and when the cleaning plug 13 enters the heating conveying pipe 2, the brush head 23 contacts with the inner wall of the heating conveying pipe 2. Preferably, guide pieces 25 mounted on the spherical surface of the cleaning plug 13 are arranged on two sides of the spring 22, and the guide pieces 25 are symmetrically arranged on two sides of the front surface of the protection plate 24 and used for limiting the dumping direction of the spring 22, so that the brush head 23 can be in contact with the inner wall surface of the heating conveying pipe 2.
Working principle: after the cleaning operation is completed, the inner wall of the heating conveying pipe 2 needs to be coated with a protective coating, at this time, the coating part 21 coated with the protective coating is arranged on the cleaning plug 13, and after the motor is started, the traction rope 17 drives the cleaning plug 13 to reciprocate. Taking fig. 5 as an example, when the cleaning plug 13 moves to the left end, the back surface of the protection plate 24 touches the inner wall of the heating conveying pipe 2, and the brush head 23 is isolated from touching the inner wall of the heating conveying pipe 2. When the cleaning plug 13 moves to the right end, the brush head 23 touches the heating conveying pipe 2, and the inner wall of the heating conveying pipe 2 is coated when the cleaning plug 13 advances, so that the coating operation is realized.
There are, of course, many other embodiments of the invention that can be made by those skilled in the art in light of the above teachings without departing from the spirit or essential scope thereof, but that such modifications and variations are to be considered within the scope of the appended claims.
