[0041] See Figures 1-4 A reciprocating high-pressure cleaning device, the reciprocating high-pressure cleaning device includes a moving mechanism that reciprocates along the conveying direction of the mesh belt conveying device and a spraying mechanism fixedly connected to the moving mechanism, and the spraying mechanism faces the mesh belt conveying device;

[0042] The spraying mechanism includes a water inlet pipe 11, a main pipe 12, and a spray head 13 connected in sequence, and the spray head 13 faces the mesh belt conveying device; the water inlet pipe 11 is set as a flexible pipe, and a support bearing 14 is sleeved on the outer wall of the flexible pipe. A plurality of support bearings 14 are provided, and the flexible pipe between the support bearing 14 closest to the main pipe 12 and the main pipe 12 is higher than the ground, and the flexible pipe between adjacent two support bearings 14 is higher than the ground.

[0043] Through the implementation of the above technical solution, the moving mechanism of the reciprocating high-pressure cleaning device can realize reciprocating movement along the conveying direction of the mesh belt conveying device, and the spraying mechanism can realize reciprocating spraying along the conveying direction of the mesh belt conveying device by being connected to the moving mechanism.

[0044] When the mesh belt holes of the mesh belt conveying device are blocked by powdery materials, it will affect the drying quality of the pre-drying device. By using the reciprocating high-pressure cleaning device to repeatedly spray the surface of the mesh belt, the materials originally blocked in the mesh belt holes can be cleaned, realizing the cleaning of the mesh belt conveying device and enabling it to restore the drying effect.

[0045] The water inlet pipe 11 of the spray washing mechanism is connected to a high-pressure water source to provide cleaning water for the spray washing mechanism. This cleaning water first enters the main pipe 12 to achieve preliminary confluence, and then is sprayed towards the mesh belt conveying device through the spray head 13. The spray head 13 has a certain spraying angle. According to this spraying angle, combined with the conveying width of the mesh belt conveying device, the number of spray heads 13 used and the relative positions between multiple spray heads 13 can be determined.

[0046] In order to obtain a better spray washing effect, the moving mechanism can be set to move towards the mesh belt conveying device, so that there is a greater relative speed between the water flow sprayed by the spray head 13 and the mesh belt holes, and the water flow has a greater impulse when impacting the mesh belt holes.

[0047] In one implementation, the spray heads 13 are arranged side by side along the width direction of the mesh belt conveying device, and the spraying coverage range of this row of spray heads 13 can meet the full coverage of the width of the mesh belt conveying device.

[0048] In another implementation, the spray heads 13 can be set to at least two rows, and the adjacent two rows of spray heads 13 can cooperate with each other to achieve more effective cleaning of the mesh belt conveying device. Preferably, the adjacent two rows of spray heads 13 are staggered, so that the water flow sprayed by the spray heads 13 can more evenly cover the surface of the mesh belt conveying device.

[0049] Preferably, the angles of the multiple rows of spray heads 13 are different. Among them, the first row of spray heads 13 that comes into contact with the mesh belt conveying device is set to have a smaller included angle with the mesh belt conveying device. Through the spraying action of this spray head 13, a better vibration effect on the mesh belt conveying device can be obtained, so as to loosen the material between the material and the mesh belt conveying device, facilitating the subsequent rows of spray heads 13 to wash these materials, and thus effectively achieving the purpose of peeling off the material from the mesh belt conveying device.

[0050] In this implementation, preferably, the moving mechanism includes a driving structure and a connecting structure 3. The driving structure includes a driving body 21 and a chain transmission device fixedly arranged on the driving body 21;

[0051] The chain transmission device includes a motor 22, sprockets 23 located at both ends of the driving body 21, and a chain 24 that cooperates with the sprockets 23. The driving body 21 is arranged along the length direction of the mesh belt conveying device, and the length of the driving body 21 is greater than the length of the mesh belt conveying device. The motor 22 is connected to one of the sprockets 23 to drive the sprocket 23 to rotate;

[0052] The connecting structure 3 is fixedly connected to the chain 24, and the spray washing mechanism is fixedly connected to the connecting structure 3.

[0053] The driving structure is set as a chain drive. The motor 22 drives the sprocket 23 and drives the chain 24 to rotate. The connecting structure 3 is fixedly connected to the chain 24. Therefore, it can move along the length direction of the mesh belt conveying device together with the chain 24, so that the spraying and washing mechanism fixed on the connecting structure 3 can realize the spraying and washing effect on the mesh belt conveying device. Since the length of the driving body 21 is greater than the length of the mesh belt conveying device, therefore, by reasonably setting the position and length of the driving structure, the spraying and washing mechanism can effectively clean both ends of the mesh belt conveying device, so as to realize the spraying and washing operation on all positions of the mesh belt conveying device.

[0054] Since the length of the mesh belt conveying device is usually relatively long, therefore, the length of the chain 24 will also be very long. The long chain 24 will vibrate during the movement. In order to avoid the vibration of the chain 24 affecting the stability of the spraying and washing mechanism, therefore, the driving body 21 is also provided with chain guards 241. The two chain guards 241 are arranged in pairs, and the two chain guards 241 are respectively located above and below the chain 241. Through the two chain guards 241, reliable limit of the chain 24 can be realized, avoiding the vibration of the chain 24 during the movement, and also avoiding the position change of the chain 24 in the height direction.

[0055] In order to ensure the reliability of driving the spraying and washing mechanism, two sets of structures in which the sprockets 23 and the chain 24 cooperate are respectively arranged on both sides of the driving body 21. Corresponding to the chains 24 on both sides, two sets of chain guards 241 are also arranged to limit the chains 24 on both sides respectively.

[0056] The connecting structure 3 can be connected to the side of the chain 24 and detachably connected to some sections of the chain 24 through bolts, or directly welded to the chain 24 to ensure the reliability of the connection between the connecting structure 3 and the chain 24.

[0057] Preferably, two sets of structures in which the sprockets 23 and the chain 24 cooperate are respectively arranged on both sides of the driving body 21. The motor 22 drives the sprockets 23 on both sides simultaneously through a concentric shaft, so that the chains 24 on both sides can rotate synchronously. The connecting structure 3 is fixedly connected to the chains 24 on both sides respectively, so that the chains 24 on both sides can drive the connecting structure 3 synchronously, ensuring the reliability and stability of the movement of the spraying and washing mechanism.

[0058] In this embodiment, preferably, the connecting structure 3 is fixedly connected to the side facing the mesh belt conveying device of the chain 24.

[0059] The connecting structure 3 is connected to the chain 24 located below.

[0060] In this embodiment, preferably, position switches are respectively arranged at both ends of the driving body 21, and the connecting structure 3 is provided with a position plate that cooperates with the position switches, and the position plate and the position switches cooperate to control the forward and reverse rotations of the motor 22.

The reciprocating movement of the chain 24 is controlled by the forward and reverse rotations of the motor 22, and through this reciprocating movement, the continuous and repeated cleaning of the belt conveyor equipment is achieved.

[0062] Position switches are respectively arranged at both ends of the driving body 21. The position switches can be photoelectric switches or travel switches.

[0063] When the position switch is set as a photoelectric switch, when the position plate moves to the end of the driving body 21, it will block the light emitted by the photoelectric switch. At this time, the photoelectric switch acts, and the control system believes that the spraying mechanism has moved in place, and will control the motor 22 to reverse, so that the sprocket 23 rotates in the reverse direction, and the chain 24 starts to retract. Then, the connecting structure 3 fixedly connected to the chain 24 can achieve the return journey. Repeating the above steps, the spraying mechanism can achieve the repeated cleaning of the belt conveyor equipment.

[0064] When the position switch is set as a travel switch, when the position plate moves to the end of the driving body 21, it will contact the detection rod of the travel switch. At this time, the travel switch acts, and the control system believes that the spraying mechanism has moved in place, and will control the motor 22 to reverse, so that the sprocket 23 rotates in the reverse direction, and the chain 24 starts to retract. Then, the connecting structure 3 fixedly connected to the chain 24 can achieve the return journey. Repeating the above steps, the spraying mechanism can achieve the repeated cleaning of the belt conveyor equipment.

[0065] In this embodiment, preferably, the reciprocating high-pressure cleaning device further includes a counter, and the counter counts the number of times the two position switches cooperate with the position plate.

[0066] Set the number of times of cleaning the belt conveyor equipment. Assume that after cleaning N times, the cleaning is completed. Each time the position switch acts, it means that the spraying mechanism has completed one cleaning of the belt conveyor equipment. At this time, the counter counts once. When the counter counts to N, the control system believes that the cleaning work has been completed, and will stop cleaning the belt conveyor equipment. At this time, stop the motor 22 to make the moving mechanism stop moving, and at the same time, the water inlet pipe 11 can also be stopped to stop supplying water to the spraying mechanism.

[0067] In this embodiment, preferably, the spraying mechanism further includes a control valve for controlling the opening and closing of the spray head 13.

[0068] The opening and closing of the nozzle 13 is controlled by a control valve. When the mesh belt conveyor equipment needs to be cleaned, the control can be turned on so that the nozzle 13 starts to spray water.

[0069] The closing of the control valve can be controlled by the counter. When the counter detects that the count reaches a specified value, the control valve will be closed.

[0070] In this embodiment, preferably, the counter controls the control valve to be closed.

[0071] In an embodiment, preferably, the driving structure also includes a guide rail 25 and a guide slider 32 that cooperate with each other to realize the guiding function.

[0074] By coordinating the rotation speed of the motor 22 and the flow rate of the head 13, a better cleaning effect on the mesh belt conveyor can be achieved.

[0075] In one embodiment, the mesh belt conveyor device is stationary, and the relative speed between the spray cleaning mechanism and the mesh belt conveyor device can be controlled by controlling the rotation speed of the motor 22 .

[0076] In another embodiment, the mesh-belt conveyor device and the driving structure move relative to each other, and therefore, the relative speed between the spray cleaning mechanism and the mesh-belt conveyor device is the sum of the speed of the driving structure and the speed of the mesh-belt conveyor device.

[0077] In this embodiment, preferably, a water tank 4 is provided below the mesh belt conveyor.

[0078] The spraying mechanism sprays water toward the mesh belt conveying device, and the sprayed water will fall into the water tank 4 below through the conveying surface. The water tank 4 can collect the cleaning water.
