Description

Technical Field

[0001] This invention relates to the field of material conveying equipment, specifically to an adaptive dewatering device for belt conveyors. Background Technology

[0002] When conveyor belts transport materials, water spraying is sometimes used to suppress dust, especially when there is a certain height difference during transportation. If water spraying is not carried out in time, a large amount of dust will be thrown out from the end of the conveyor belt, thus polluting the environment and causing certain harm to the workers' health.

[0003] However, after the materials are transported to the designated area, there will still be residual ash and water on the surface of the conveyor belt. If it is not cleaned in time, it will enter the idler rollers and other components, which will reduce the surface friction of the belt conveyor, cause uneven tension of the entire cross section of the belt, and accelerate the wear of the conveyor belt components due to uneven stress, resulting in a decrease in the life of the entire machine. In severe cases, it may cause the belt to run off-center, which can easily damage the belt and affect safe production. Summary of the Invention

[0004] To address the issue of dust and water adhering to the return section of the belt in the prior art, which is difficult to clean, this invention proposes an adaptive dewatering device for belt conveyors.

[0005] To achieve the above objectives, the technical solution proposed by this invention is as follows:

[0006] An adaptive dewatering device for a belt conveyor consists of a support group (1), a roller bearing (2), a roller shaft (3), a distance measuring module (4), an adaptive pressing device (5), a mesh roller (6), a conveyor belt (7), a redirecting roller (8), an air circuit (9), and a controller (10).

[0007] The support group (1) is located below the entire belt conveyor. The support group (1) is located in the return section of the conveyor belt redirection roller. The support group (1) consists of a left support (1-1), a right support (1-2), a left support shaft (1-3), a right support shaft (1-4), and four side bearings (1-5). The left support shaft (1-2) is installed above the left support (1-1), and two side bearings (1-5) are installed on the left support shaft (1-2). The right support shaft (1-4) is installed above the right support (1-2), and two side bearings (1-5) are installed on the right support shaft (1-4).

[0008] The roller bearing (2) is installed on both sides of the roller shaft (3) to fix the roller shaft (3). The outer ring of the roller bearing (2) has a groove to fit the front tension belt (5-4) and the rear tension belt (5-5).

[0009] The mesh roller (6) is composed of spokes (6-1), tubular skin (6-2), and cotton and linen mesh (6-3). The cotton and linen mesh (6-3) is in contact with the conveyor belt (7) of the conveyor to absorb and scrape water. The roller shaft (3) is located at the axis of the mesh roller (6). The cotton and linen mesh (6-3) is made of porous fiber material.

[0010] The ranging module consists of a left sensor mounting bracket (4-1), a left laser displacement sensor (4-2), a right sensor mounting bracket (4-3), a right laser displacement sensor (4-4), and a photoelectric sensor (4-5). The left sensor mounting bracket (4-1) is installed on the middle crossbeam of the left support (1-1), the right sensor mounting bracket (4-3) is installed on the middle crossbeam of the right support (1-2), the left laser displacement sensor (4-2) is installed on the left sensor mounting bracket (4-1) with its sensing direction facing upward, and the right laser displacement sensor (4-4) is installed on the right sensor mounting bracket (4-3) with its sensing direction facing upward.

[0011] A photoelectric sensor (4-5) is installed on the upper front part of the left bracket, and the sensing direction is towards the mesh roller (6).

[0012] The adaptive clamping device (5) consists of a pre-tightening clamp (5-1), a front servo motor (5-2), a rear servo motor (5-3), a front tension belt (5-4), a rear tension belt (5-5), a front tension sensor (5-6), and a rear tension sensor (5-7).

[0013] The left side of the front tension belt (5-4) is bolted to the front middle part of the left bracket (1-1), and passes over the left bracket shaft (1-3) and right bracket shaft (1-4) to connect to the front tension sensor (5-6). The left side of the rear tension belt (5-5) is bolted to the rear middle part of the left bracket (1-1), and passes over the left bracket shaft (1-3) and right bracket shaft (1-4) to connect to the rear tension sensor (5-7).

[0014] The lower side of the front tension sensor (5-6) is fixed to the front compensation belt (5-8) by bolts. The lower side of the front compensation belt (5-8) is connected to the front pretension clamp (5-1-A) and fixed by bolts. The lower side of the rear tension sensor (5-7) is fixed to the rear compensation belt (5-9) by bolts. The lower side of the rear compensation belt (5-9) is connected to the rear pretension clamp (5-1-B) and fixed by bolts.

[0015] The front servo motor (5-2) is bolted to the front surface of the right bracket (1-2), and the shaft of the front servo motor (5-2) is inserted into the front preload clamp (5-1-A) and locked by bolts. The rear servo motor (5-3) is bolted to the rear surface of the right bracket (1-2), and the shaft of the rear servo motor (5-3) is inserted into the rear preload clamp (5-1-B) and locked by bolts.

[0016] The air circuit (9) consists of a nozzle (9-1), an air pipe (9-2), a pressure sensor (9-3), an electromagnetic pressure regulating valve (9-4), and an air source (9-5). The nozzle (9-1) is connected to the electromagnetic pressure regulating valve (9-4) and the pressure sensor (9-3) by the air pipe (9-2), and the electromagnetic pressure regulating valve (9-4) is connected to the air source (9-5) by the air pipe (9-2).

[0017] The controller (10) detects data from the left laser displacement sensor (4-2), the right laser displacement sensor (4-4), the photoelectric sensor (4-5), the front tension sensor (5-6), the rear tension sensor (5-7), and the pressure sensor (9-3), and controls the front servo motor (5-2), the rear servo motor (5-3), and the electromagnetic pressure regulating valve (9-4).

[0018] The specific control process is as follows:

[0019] First, the controller (10) initializes and powers on, and then collects the values ​​of the front tension sensor (5-6), rear tension sensor (5-7), left laser displacement sensor (4-2), right laser displacement sensor (4-4), photoelectric sensor (4-5), and pressure sensor (9-3) in real time; at the same time, the controller (10) controls the front servo motor (5-2) and the rear servo motor (5-3).

[0020] Control the front servo motor (5-2) to loosen the front tension belt (5-4) so ​​that the value of the front tension sensor (5-6) reaches the minimum; control the rear servo motor (5-3) to loosen the rear tension belt (5-5) so that the value of the rear tension sensor (5-7) reaches the minimum; so that the mesh roller (6) is completely separated from the conveyor belt (7).

[0021] Then, the distance variable of the left laser displacement sensor (4-2) is read and recorded as H1, and the distance variable of the right laser displacement sensor (4-4) is recorded as H2. The intersection line of the lower surface of the conveyor belt (7) and the axis of the mesh roller (6) is estimated using equation (1). The vertical height H of this intersection line and the line connecting the left laser displacement sensor (4-2) and the right laser displacement sensor (4-4) is calculated. * .

[0022] (1)

[0023] Ignoring the vibration of the mesh roller (6) during operation, the distance H between the axis of the mesh roller (6) and the plane formed by the axes of the left support shaft (1-3) and the right support shaft (1-4) during operation under ideal conditions can be calculated by equation (2).

[0024] (2)

[0025] Where D is the outer diameter of the mesh roller (6); H0 is the distance between the plane formed by the right laser displacement sensor (4-4) and the axes of the left support shaft (1-3) and the right support shaft (1-4).

[0026] Assuming that the mesh roller (6) moves up and down within the central symmetry plane of the support group (1), the horizontal distance from the axis of the mesh roller (6) to the axis of the left support shaft (1-3) or the right support shaft (1-4) is equal, denoted as V; then when performing force analysis on the axis of the roller shaft (3) in the front view section, the angle between the front tension belt (5-4) and the gravity direction of the roller shaft (3) is θ, which can be calculated by equation (3).

[0027] (3)

[0028] Assuming the total mass of the mesh roller (6), roller bearing (2), and roller shaft (3) is M, the gravitational acceleration is g, and the required compressive stress of the mesh roller (6) on the conveyor belt (7) is N, the required tension force Fn to be applied to the belt can be obtained from equation (4):

[0029] (4)

[0030] From equations (3) and (4), we can obtain:

[0031] (5)

[0032] Therefore, the controller (10) adjusts the front servo motor (5-2) and the rear servo motor (5-3), and adjusts the values ​​of the front tension sensor (5-6) and the rear tension sensor (5-7) by Fn, so that the mesh roller (6) can press the conveyor belt (7) within a certain range, and its compressive stress is N, thereby performing adaptive adjustment.

[0033] During machine operation, the photoelectric sensor (4-5) can collect the rotation speed of the mesh drum (6) in real time and feed it back to the controller (10). The controller (10) controls the output of the electromagnetic pressure regulating valve (9-4) according to the rotation speed signal given by the photoelectric sensor (4-5) so that when the mesh drum (6) runs fast, the air pressure and air flow of the nozzle are high and large, and when the mesh drum (6) runs slow, the air pressure and air flow of the nozzle are low, which is more conducive to saving air supply and achieving a certain drying effect.

[0034] The pressure sensor (9-3) is connected to the controller (10) and provides real-time feedback on the pressure of the air pipe (9-2), making the entire air pressure drying system a closed-loop control.

[0035] In summary, this invention installs an adaptive dewatering device for belt conveyors below the conveyor belt. Relying on various sensors to collect and provide real-time feedback information, this device has functions such as rolling dewatering, adjustable clamping force, adjustable air pressure spray drying, and replaceable cotton and linen mesh, ensuring that the advantages of mesh roller dewatering and spray drying are fully utilized under economical and practical conditions.

[0055] The left side of the front tension belt 5-4 is fixed to the front middle part of the left bracket 1-1 with bolts, and after passing around the left bracket shaft 1-3 and the right bracket shaft 1-4 from the left side, it is connected to the upper part of the front tension sensor 5-6.

[0056] The left side of the rear tension belt 5-5 is fixed to the middle and rear part of the left bracket 1-1 with bolts, and after passing around the left bracket shaft 1-3 and the right bracket shaft 1-4 from the left side, it is connected to the upper part of the rear tension force sensor 5-7.

[0057] The lower side of the front tension sensor 5-6 is fixed to the front compensation belt 5-8 by bolts, and the lower side of the front compensation belt 5-8 is connected to the front preload clamp 5-1-A and fixed by bolts.

[0058] The lower side of the rear tension sensor 5-7 is fixed to the rear compensation belt 5-9 by bolts, and the lower side of the rear compensation belt 5-9 is connected to the rear preload clamp 5-1-B and fixed by bolts.

[0059] The front servo motor 5-2 is bolted to the front surface of the right bracket 1-2, and the shaft of the front servo motor 5-2 is inserted into the front preload clamp 5-1-A and locked by bolts; the rear servo motor 5-3 is bolted to the rear surface of the right bracket 1-2, and the shaft of the rear servo motor 5-3 is inserted into the rear preload clamp 5-1-B and locked by bolts.

[0060] like Figure 5As shown, the mesh roller 6 is composed of spokes 6-1, a cylindrical shell 6-2, and a cotton and linen mesh 6-3. The cotton and linen mesh 6-3 is in contact with the conveyor belt 7 of the conveyor to absorb and scrape water. The roller shaft 3 is located at the axis of the mesh roller 6.

[0062] like Figure 7 and 8 The figure shown is a geometric calculation diagram for calculating the deflection angle Θ and the applied stress, where:

[0063] The distance is the plane formed by the axes of the right laser displacement sensor 4-4, the left support shaft 1-3, and the right support shaft 1-4. For the distance variable of the left laser displacement sensor 4-2, For the distance variable of the right laser displacement sensor 4-4, The perpendicular height of the line connecting the lower surface of the conveyor belt 7 and the axis of the mesh roller 6 to the line connecting the left laser displacement sensor 4-2 and the right laser displacement sensor 4-4.

[0067] Pressure sensor 9-3 is connected to controller 10 and provides real-time feedback on the pressure of air pipe 9-2, making the entire air pressure drying system a closed-loop control system.

[0074] 6. Let F1 = F2, and repeat the above steps 3 to 5 until t time intervals have elapsed, where t > 10.

[0075] 7. Take the tension at this moment as the initial tension F of our tension belts 5-4 and 5-5.

[0076] 8. Turn on laser displacement sensors 4-2 and 4-4, measure the values ​​of H1 and H2, and then calculate H using Equation 1. * , as the reference height.

[0077] 9. The deflection angle θ can be calculated using formula 3 from the known parameters V, H0, D, D1, D2.

[0080] 12. The difference between the previous sample and the subsequent sample is denoted as ΔF.

[0081] 13. Control the front servo motor 5-2 and the rear servo motor 5-3 to deflect by a certain angle φ.

[0082] 14. Repeat steps 11-12.

[0083] 15. If the difference ΔF increases, the front servo motor 5-2 and the rear servo motor 5-3 will deflect 2φ in the opposite direction of φ. If ΔF is negative, they will deflect 2φ in the direction of φ.

[0084] 16. Repeat steps 11-15 until the machine is powered off.

[0085] 17. After the photoelectric sensor 4-5 collects the speed of the mesh roller 6, the desired pressure P is obtained after proportional calculation. * .

[0086] 18. Read the value P1 of pressure sensor 9-3.

[0087] 19. Place P * The difference between P1 and P1 is ΔP.

[0088] 20. If ΔP is not less than 0, adjust the valve core of the electromagnetic pressure regulating valve 9-4 according to a certain ratio to make its opening larger; conversely, if ΔP < 0, adjust the valve core of the electromagnetic pressure regulating valve 9-4 according to a certain ratio to make its opening smaller, thereby achieving the purpose of pressure regulation.

Relying on various sensors to collect and provide real-time feedback information, this device has functions such as rolling dewatering, adjustable clamping force, adjustable air pressure spray drying, and replaceable cotton and linen mesh, ensuring that the advantages of mesh roller dewatering and spray drying are brought into play under economical and practical conditions.
