[0010] In some embodiments, the lifting power mechanism includes a pneumatic cylinder, an oil cylinder or a linear motor.

[0011] In some embodiments, the telescopic structure comprises a telescopic column.

[0012] In some embodiments, when the diverter baffle is moved to abut against the conveyor belt, the angle between the diverter baffle and the conveying direction of the conveyor belt is less than 90°.

[0013] In some embodiments, the detection mechanism includes a sensing paddle, which is hinged to the full bin line of the upper hopper and is arranged opposite to the conveyor belt; when the upper hopper is full, the sensing paddle is lifted up by the sludge and triggered.

[0048] After the sludge in the water treatment unit is dried, it needs to be sent to the sludge storage of the power plant and enter the upper hopper 11 for mixed combustion. Due to the limited capacity of the upper hopper, the dried sludge is currently transported to the sludge storage of the power plant by a conveyor belt, and then the sludge is directly unloaded on the ground, and then the driver controls the loader to transfer the sludge on the ground to the upper hopper for loading. This not only wastes manpower, but also requires the use of loaders in multiple places. Sometimes the loader is working at other stations, so it cannot load materials in time, and the operation is extremely inflexible.

[0049] To this end, the utility model provides a divertible sludge conveying mechanism for conveying dried sludge from a water treatment unit, so as to convey the dried sludge to an upper hopper of a sludge storage bin of a power plant. In particular, the sludge can be directly conveyed into the upper hopper. When the upper hopper is full, the conveying direction can be changed to the ground in time, which is convenient, labor-saving and fast, and truly ensures that there is sufficient sludge in the upper hopper. The unloading time of the sludge storage bin is self-determined, and is no longer limited by whether the loader is idle, which is more flexible and convenient.

[0050] In a specific embodiment, the divertable sludge conveying mechanism includes a conveyor belt 1 and a diverter system, and the discharge end of the conveyor belt 1 extends to the feed port of the upper hopper 11; the diverter system includes a mounting frame 2, a diverter baffle 3, a power mechanism, a detection mechanism, and a controller, and the diverter baffle 3 can be movably arranged on the mounting frame 2; the power mechanism is transmission-connected to the diverter baffle 3, and is used to drive the diverter baffle 3 to move against the conveyor belt 1, and the two sides of the diverter baffle 3 are respectively located on both sides of the conveyor belt 1, thereby intercepting the sludge from continuing to move forward, so as to change the moving direction of the sludge to the side of the conveyor belt 1; the detection mechanism is arranged at the feed port of the upper hopper 11 to detect the amount of sludge in the upper hopper 11; the controller is connected to the detection mechanism and the driving mechanism.

[0051] The discharge end of the conveyor belt 1 of the divertible sludge conveying mechanism directly extends to the feed inlet of the upper hopper 11. Figure 1As shown by the arrow, the sludge can be directly transported to the upper hopper 11. When the upper hopper 11 is full, the direction of the conveying sludge of the conveyor belt 1 can be changed by the diversion system. The detection mechanism of the diversion system is arranged at the feeding port of the upper hopper 11 to detect the amount of sludge in the upper hopper 11. When it is detected that the upper hopper 11 is full, a signal can be transmitted to the controller. The controller can control the power mechanism to drive the diversion baffle 3 to move against the conveyor belt 1, and the two sides of the diversion baffle 3 are respectively located on the two sides of the conveyor belt 1. The sludge on the conveyor belt 1 is intercepted by the diversion baffle 3 and cannot be further transported to the upper hopper 11. The sludge falls to the ground from the side of the conveyor belt 1 autonomously, that is, the conveying direction of the sludge is changed. , from conveying to the upper hopper 11 to conveying to the ground. After the sludge in the upper hopper 11 is gradually reduced, the diverter baffle 3 can also be driven to leave the conveyor belt 1, so that the sludge can continue to be conveyed to the upper hopper 11. This makes the sludge transfer more flexible and can complete the sludge transmission at one time. It will not stop suddenly due to the full hopper, and the upper hopper 11 will not be cut off due to the loader's failure to load in time. The sludge that is unloaded to the floor because the upper hopper 11 is full can be transferred when the loader is idle. It is more flexible to operate and reduces the number of times the loader is used. It is convenient, labor-saving and fast. It truly ensures that there is enough sludge in the upper hopper 11. The unloading time of the sludge warehouse is self-determined, and is no longer limited by whether the loader is idle. It is more flexible and convenient.

[0052] In some embodiments, the diverter baffle 3 is arranged on the mounting frame 2 through the rotating shaft 4, and the rotating shaft 4 is perpendicular to the conveyor belt 1; the power mechanism is a rotary power mechanism, and the rotary power mechanism is connected to the rotating shaft 4 to drive the rotating shaft 4 to drive the diverter baffle 3 to rotate, that is, the movement mode of the diverter baffle 3 is rotation. When sludge needs to be transported to the upper hopper 11, the diverter baffle 3 is in a direction parallel to the moving direction of the conveyor belt 1, which will not affect the forward movement of the sludge. When the upper hopper 11 is full, the diverter baffle 3 is driven by the rotary power mechanism from the moving direction parallel to the conveyor belt 1 to the moving direction intersecting with the conveyor belt 1, and ensure that the two sides of the diverter baffle 3 are respectively located on both sides of the conveyor belt 1.

[0053] There can be multiple types of rotating power mechanisms. In some embodiments, the rotating power mechanism includes a rotating motor, which is transmission-connected to the rotating shaft 4 of the diverter baffle 3. The output end of the rotating motor rotates directly to drive the rotating shaft 4 to rotate, thereby driving the diverter baffle 3 to rotate to a specified position.

[0054] See also Figure 4In other embodiments, the rotary power mechanism includes a gear 5, a rack 6 and a linear drive mechanism 7. The gear 5 is sleeved on the rotating shaft 4 of the diverter baffle 3, and the rack 6 is meshed with the gear 5; the linear drive mechanism 7 is transmission connected to the rack 6 to drive the rack 6 to move, and through the cooperation of the gear 5 and the rack 6, the linear motion is converted into rotary motion, thereby driving the diverter baffle 3 to rotate to a specified position.

[0055] See also Figure 5 and Figure 6 In other embodiments, the diverter baffle 3 is located on the conveyor belt 1 and is connected to the mounting frame 2 through a telescopic structure, and the telescopic direction of the telescopic structure is perpendicular to the conveyor belt 1; the power mechanism is a lifting power mechanism, and the lifting power mechanism is transmission-connected to the diverter baffle 3 or the telescopic structure to drive the diverter baffle 3 to be lifted and lowered, which can drive the diverter baffle 3 to be lifted and lowered. When the diverter baffle 3 is raised to be higher than the conveyor belt 1, it will not affect the conveying of sludge by the conveyor belt 1. When the diverter baffle 3 is lowered to the bottom of the diverter baffle 3 and rests on the conveyor belt 1, the conveying direction of the sludge can be changed.

[0056] In some embodiments, the lifting power mechanism includes a pneumatic cylinder, an oil cylinder or a linear motor.

[0057] In some embodiments, the telescopic structure includes a telescopic column 8 .

[0058] In some embodiments, when the diverter baffle 3 is moved to abut against the conveyor belt 1, the angle between the diverter baffle 3 and the conveying direction of the conveyor belt 1 is less than 90°. Figure 2 When the angle A shown is 90°, the sludge will move to both sides of the diversion baffle 3. Figure 2 In the direction of the arrow shown, the sludge unloaded on the ground is not concentrated enough; Figure 3 The angle B shown is less than 90° and may be 45°. In this case, the sludge will move more toward one side of the diversion baffle 3. Figure 3 In the direction of the arrow shown, the sludge unloaded to the ground is more concentrated, which is convenient for the loader to transfer it to the upper hopper 11.

[0059] In a further embodiment, the detection mechanism may include a sensor, such as an infrared sensor, etc. The sensor is arranged at the full bin line of the upper hopper. When the upper hopper is full, the sensor detects the sludge and transmits a signal to the controller.

[0060] In some embodiments, the detection mechanism includes an induction paddle 9, which is hinged at the full-bin line of the feeding hopper 11 and is disposed opposite to the conveyor belt 1; when the feeding hopper 11 is full, the induction paddle 9 is lifted by the sludge and triggered, and the induction paddle 9 transmits a signal to the controller. The controller receives the signal and controls the power mechanism, and the power mechanism drives the diversion baffle 3 to move to a specified position to block the forward movement of the sludge, change the sludge transmission direction and discharge it to the floor; when the sludge in the feeding hopper 11 is consumed, the induction paddle 9 naturally drops, the controller receives the signal and controls the power mechanism, and the power mechanism drives the diversion baffle 3 to return to its original position, and the sludge can be directly conveyed into the feeding hopper 11 again, and the cycle continues until this unloading is completed. It truly realizes that the hopper is full of sludge, the unloading time in the sludge workshop is self-defined, without any restrictions, and it is more flexible and convenient.

[0061] To ensure that the diversion baffle 3 abuts against the conveyor belt 1 while not affecting the normal operation of the conveyor belt 1, in some embodiments, a sealing strip 30 is provided at the bottom of the diversion baffle 3, and the diversion baffle 3 abuts against the conveyor belt 1 through the sealing strip 30. The sealing strip 30 is made of a deformable material, such as silica gel, rubber, or plastic.

The discharge guide plate 10 and the diversion baffle 3 are arranged in sequence along the conveying direction of the conveyor belt 1, and the discharge guide plate 10 is disposed on one side of the conveyor belt 1 and is inclined to the ground. When the feeding hopper 11 is full and the sludge transmission direction is changed, the sludge is discharged to the floor through the discharge guide plate 10.
