The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
A sludge low-temperature belt type drying conveyor belt is structurally illustrated by figures 1 and 2, and as shown in the figure, the device comprises: drive roll 1, support frame 6, driven roller set and conveyer belt 2. The driving roller 1 and the driven roller group are respectively arranged at two ends of the support frame 6, and the driving roller 1 is connected with the driving motor 11. In operation, the driving roller 1 can be driven to rotate by the driving motor 11, so that the conveyor belt 2 can carry out the conveying operation of the mud strips.
The driven roller group is used for making a bend in a part of the conveyor belt 2 and separating sludge residue from the conveyor belt 2 by using the bend of the conveyor belt 2. Specifically, the driven roller group includes: first backing roll 3, second backing roll 4 and pinch roller 5, second backing roll 4 is located first backing roll 3 below, pinch roller 5 is located inside the triangle-shaped that drive roll 1, first backing roll 3 and second backing roll 4 constitute. The first supporting roller 3 and the second supporting roller 4 are used for being matched with the driving roller 1, the conveying belt 2 is tensioned on the inner side of the conveying belt 2, and the pressing roller 5 is used for pressing against the outer wall of the conveying belt 2 to enable the conveying belt 2 to be bent.
In operation, the conveyor belt 2 is wound around the outside of the drive roller 1, the first support roller 3, and the second support roller 4, and the pinch roller 5 is disposed outside the conveyor belt 2. Because the pinch roller 5 is located inside the triangle formed by the drive roller 1, the first support roller 3 and the second support roller 4, the pinch roller 5 can support the conveyor belt 2 outside the conveyor belt 2, the support effect can bend the conveyor belt 2 wound between the first support roller 3 and the second support roller 4, and when the bending radius of the conveyor belt 2 is smaller than the minimum bending radius of sludge residue, the sludge residue attached to the conveyor belt 2 can fall off.
In the existing low-temperature belt type sludge drying process, the conveyor belt 2 for conveying the sludge is usually made of a woven metal mesh. In addition, in order to prevent the corrosion of the metal mesh grid caused by the chemical substances in the sludge, a protective film made of polyamide or polyimide is added on the metal mesh surface by the skilled person, so as to prolong the service life of the conveyor belt 2. Because of the good flexibility of the components of the prior art conveyor belt 2, the conveyor belt 2 can be formed with local deformations having a small bending radius. When the conveyor belt 2 attached with the sludge residue moves to a deformation area, the sludge residue can be cracked due to the fact that the bending radius is too small, the bonding effect between the sludge and the conveyor belt 2 can be damaged in the cracking process, and the sludge residue is separated from the conveyor belt 2.
Since the hot air is always circulated in the belt drying plant, the sludge residue attached to the conveyor belt 2 is dried from the outside to the inside. Since the degree of sludge flexibility is proportional to its water content, surface-dried sludge residues will break when the conveyor belt 2 bends.
Since the second supporting roller 4 is disposed below the first supporting roller 3, after the mud strip is separated from the conveyor belt 2, the conveyor belt 2 with the mud residue is firstly contacted with the second supporting roller 4. In order to improve the shedding effect of sludge remaining at this position, the diameter of the second support roller 4 is optionally smaller than the diameter of the drive roller 1. Because the bending radius of the conveyor belt 2 is determined by the diameter of the roller which plays a supporting role in the conveyor belt, the sludge remained in the area can be intensively fallen off due to the small diameter of the second supporting roller 4, and the collection of the sludge by workers is facilitated.
As shown in fig. 3, which is a schematic structural diagram of the supporting frame 6 in this embodiment, as shown in the figure, the supporting frame 6 includes a connecting arm 61 and a supporting arm, a first end of the connecting arm 61 is rotatably connected with the driving roller 1, and a second end is rotatably connected with the pressure roller 5. The support arm includes first support arm 62 and second support arm 63, the one end of first support arm 62 rotates with first supporting roller 3 to be connected, and the other end links to each other with the second end of connecting arm 61, the one end of second support arm 63 rotates with second supporting roller 4 to be connected, and the other end links to each other with the second end of connecting arm 61.
Because the local needs of conveyer belt 2 produce bending deformation, consequently the conveyer belt 2 in this embodiment can have great internal stress inside, for avoiding too big internal stress to be conveyer belt 2 and damage, the support arm can set up to the telescopic link that has the flexible function of stretching out and drawing back. Specifically, the support arm includes connecting portion 621, connecting rod 622 and spring 623, the one end of connecting rod 622 links to each other with connecting portion 621, and inside the other end inserted the preset accommodation hole on connecting arm 61, the spring 623 cover is established at the connecting rod 622 outside, and the both ends of spring 623 respectively with connecting portion 621 and connecting arm 61 offset and hold. When the internal stress of the conveyor belt 2 is large, the spring 623 will be compressed, and the supporting function of the conveyor belt 2 by the two support rollers will be weakened, so that the purpose of avoiding the damage of the conveyor belt 2 is achieved.
Optionally, in order to balance the supporting effect of the two supporting rollers on the conveyor belt 2 and avoid the occurrence of local excess stress inside the conveyor belt 2, the lengths of the first supporting arm 62 and the second supporting arm 63 are equal.
In addition, in order to improve the dropping speed of the sludge residues in the device, the side wall of the compression roller 5 is also provided with a strip-shaped protrusion 51, and the strip-shaped protrusion 51 is parallel to the axis of the compression roller 5. When the strip-shaped protrusion 51 contacts the conveyor belt 2, the stress inside the conveyor belt 2 increases instantaneously, and the support arm extends and retracts. The two supporting rollers can generate periodic shaking through the telescopic action, so that the shedding speed of the sludge residue is improved.
In this embodiment, the connecting arm 61 is further provided with a cleaning roller 7, and the sludge residue that has not yet fallen off can be cleaned by the cleaning roller 7. Specifically, the second end of connecting arm 61 outwards extends has third support arm 64 be equipped with cleaning roller 7 on the third support arm 64, cleaning roller 7 is located inside the triangle-shaped that pinch roller 5, first supporting roller 3 and second backing roller 4 constitute, and cleaning roller 7's lateral wall contacts with the outer wall that is located the conveyer belt 2 between second backing roller 4 and the pinch roller 5.
Illustratively, the cleaning roller 7 may be a brush roller.
In order to avoid the cleaning roller 7 from obstructing the movement of the conveyor belt 2, the diameter of the cleaning roller 7 is optionally smaller than the distance between the first support roller 3 and the second support roller 4.
The following explains the effects of the above scheme:
this embodiment provides a mud low temperature belt conveyer belt for mummification can make conveyer belt 2 take place local deformation through driven roller set, can make mud remain to concentrate the efficient through local deformation and drop, avoids it to cause destruction to operational environment.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
