Description

Technical Field

[0001] The present invention relates to the technical field of coal conveying, and in particular to a coal conveying belt with automatic deviation adjustment and cleaning functions. Background Art

[0002] A belt conveyor is a conveying system that uses frictional drive to convey loose materials or packaged goods, and is widely used in industries such as mines, metallurgy, and coal. However, during the operation of the conveyor belt, various faults will inevitably occur, affecting the operation of the machine. Among the various problems that may occur, belt deviation is a very common and extremely harmful fault. Due to various factors (such as mechanical wear, uneven distribution of materials on the conveyor belt, and the tension of the conveyor belt itself), the conveyor belt (belt) often deviates, which not only affects production efficiency, but may also cause equipment damage and even lead to safety accidents. The traditional method of correcting belt deviation mainly relies on manual adjustment, which is inefficient and cannot respond to belt deviation problems in a timely manner.

[0003] Furthermore, due to the fact that coal itself contains a certain amount of moisture, during the conveying process, it is inevitable that a small amount of coal will stick to the belt, damaging the belt, polluting the environment, increasing the equipment burden, and also easily causing the deviation of the coal conveying belt. This requires the installation of a belt cleaner at fixed points on the belt to remove the adhered coal and ash on the belt surface. Existing cleaning devices generally use fixedly installed brushes or scrapers to clean the conveyor belt, and this cleaning method cannot completely clean the adhered coal and ash with strong adhesion. Over time, more and more adhered coal and ash accumulate on the conveyor belt, further causing the occurrence of coal conveying belt deviation.

[0004] Therefore, in order to ensure the normal conveying of the belt conveyor, and at the same time be able to clean the adhered coal and ash on the conveyor belt surface well, improve the service life of the conveyor belt and improve the conveying efficiency, it is urgent to design a coal conveying belt with automatic deviation adjustment and cleaning functions.

[0035] Embodiment

[0036] As Figures 1 to 3 As shown, a coal conveying belt with automatic deviation adjustment and cleaning functions provided by the present invention specifically includes a conveying installation frame 100. Among them, a conveying mechanism 200 for conveying coal is provided on the conveying installation frame 100, and a conveyor belt adjusting mechanism 300 is also provided on the conveying installation frame 100. Through the conveyor belt adjusting mechanism 300, the adjustment of the conveying mechanism 200 is realized. This adjustment includes the callback after the conveying direction deviates, the adjustment of the conveying tightness, and the adjustment of the belt due to the elongation of one side of the conveyor belt 210 caused by long-term use, resulting in the deviation of the conveying direction, improving the service life of the conveying mechanism 200 and ensuring the normal progress of the conveying.

[0037] Preferably, the conveying mechanism 200 includes a conveyor belt 210, a driving roller 220, a driving roller 230, and a driving motor 240. The driving motor 240 is installed on the conveying installation frame 100, the driving roller 220 and the driving roller 230 are installed on the conveying installation frame 100, the conveyor belt 210 is sleeved on the driving roller 220 and the driving roller 230. In order to ensure that the material does not slip on the conveyor belt 210 during the conveying process, anti-slip patterns are provided on the conveyor belt 210. The output end of the driving motor 240 is connected to the driving roller 220, and the driving motor 240 drives the conveyor belt 210 to convey materials.

[0038] In some preferred embodiments, a conveyor belt adjusting mechanism 300 is installed on the conveyor mounting frame 100. The conveyor belt adjusting mechanism 300 includes a mounting base 310, an adjusting assembly 320, a rotating motor 330, a mounting block 340, an electric telescopic push rod 350, a swinging motor and a pressure sensor. The mounting base 310 is installed on the conveyor mounting frame 100. The electric telescopic push rod 350 is installed on the conveyor mounting frame 100. An installation block 340 is provided at the output end of the electric telescopic push rod 350. The rotating motor 330 is installed on the mounting block 340. An adjusting assembly 320 is arranged at the output end of the rotating motor 330. The swinging motor is installed on the adjusting assembly 320. The pressure sensor is installed on the adjusting assembly 320. The conveyor belt 210 is wound around the adjusting assembly 320. The other end of the adjusting assembly 320 is installed on the mounting base 310;

[0039] A cleaning mechanism 400 is installed on the conveyor mounting frame 100 to clean the surface of the conveyor belt 210;

[0040] A control center is arranged externally. The drive motor 240, the rotating motor 330, the electric telescopic push rod 350, the swinging motor and the pressure sensor are all electrically connected to the control center. Among them, the pressure sensor is used to detect the pressure value exerted by the conveyor belt 210 on the adjusting assembly 320. The pressure sensor feeds back the detected pressure value to the control center in the form of an electrical signal for processing and analysis by the control center;

[0041] Combined with the above structure, the following analysis is carried out for three situations where the conveying direction of the conveyor belt 210 deviates during the conveying process:

[0042] 1. Due to long-term use of the conveyor belt 210, taking the conveying direction as the reference benchmark, the conveyor belt 210 is loose (elongated and deformed) on the left or right side of the conveying direction, and the conveying direction deviates to the other side of the loose side.

[0043] The pressure sensor detects that the pressure value exerted on the adjusting assembly 320 on the side where the deformation occurs decreases. Therefore, the output end of the swinging motor is controlled to swing towards the side where the pressure value decreases to drive the adjusting assembly 320 to tighten the conveyor belt 210 again (stretch it tightly), so as to adjust the deviation amount of the conveying direction (re-align the conveying direction of the conveyor belt 210);

[0044] 2. Due to long-term use of the conveyor belt 210, the conveyor belt 210 is elongated as a whole (loose as a whole), resulting in fluctuations in the conveying direction, and the conveyed material slips on the conveyor belt 210.

[0045] At this time, the pressure values acting on the adjusting component 320 all decrease, and the control center controls the rotating motor 330 to drive the adjusting component 320 to rotate to tighten the conveyor belt 210, so as to adjust the conveying direction and ensure the accuracy of the conveying direction.

[0046] 3. During the conveying process of the conveyor belt 210, due to the uneven weight of the conveyed materials, the conveying direction deflects.

[0047] Since the conveyor belt 210 itself has elasticity, during the slight deflection of the conveyor belt 210, it is defaulted that the pressure value detected by the pressure sensor remains unchanged. At this time, the control center controls the electric telescopic push rod 350 to expand and contract to adjust the conveying offset of the conveyor belt 210. That is, assuming that the conveyor belt 210 deflects 3 cm to the left in the conveying direction, the electric telescopic push rod 350 drives the conveyor belt 210 to swing 3 cm to the right in the conveying direction to restore the original conveying direction.

[0048] In some preferred embodiments, the adjusting component 320 includes a connecting plate 321, an auxiliary roller 322 and a main driving roller 323. The output end of the rotating motor 330 is connected to one side of the connecting plate 321. The main driving roller 323 is installed on the other side of the connecting plate 321 and is coaxially arranged with the output shaft of the rotating motor 330. The auxiliary roller 322 is symmetric with the main driving roller 323 about the bisector of the side of the connecting plate 321. The auxiliary roller 322 is installed on the connecting plate 321 through the swing motor and is on the same side as the main driving roller 323. Driven by the rotating motor 330, the auxiliary roller 322 rotates around the axis of the main driving roller 323 and tightens the conveyor belt 210 (that is, driven by the rotating motor 330, the main driving roller 323 rotates around the axis of the mounting seat 310).

[0049] Further, the pressure sensor is a strain gauge type pressure sensor, which is coated on the auxiliary roller 322. The resistance strain gauge utilizes the strain effect of the resistance material to convert the gravity received on the circumferential surface of the auxiliary roller 322 into a resistance change. As the strain of the object under test (here the object under test refers to the conveyor belt 210), the stress change of the conveyor belt 210 acting on the auxiliary roller 322, the resistance value inside the pressure sensor (strain gauge) will also change accordingly. The pressure sensor uses the strain effect to analyze the force data by measuring the change in resistance, so as to analyze whether the conveyor belt 210 under test is in a normal state. If the pressure sensor detects that the conveyor belt 210 is deformed, the detected data will be fed back to the control center in the form of an electrical signal. The control center controls the start of the swing motor. Driven by the swing motor, the auxiliary roller 322 laterally tightens the elongated deformation of the conveyor belt 210 until the data detected by the pressure sensor returns to a stable value (i.e., returns to the value transmitted to the pressure sensor when the conveyor belt 210 is in a normal state), preventing the conveyor belt 210 from deviating in the conveying direction due to deformation. It is worth mentioning that the length of the main drive roller 323 is longer than that of the auxiliary roller 322. The length of the auxiliary roller 322 is at least equal to the width of the conveyor belt 210. A limit block is further provided at the other end of the auxiliary roller 322 (the end away from the connecting plate 321) to prevent the conveyor belt 210 from slipping off the adjusting assembly 320. The conveyor belt 210 is wound around the auxiliary roller 322 and the main drive roller 323. Driven by the electric telescopic push rod 350, the main drive roller 323 reciprocates along the axis of the mounting seat 310 for fine adjustment of the conveying direction.

[0050] In some preferred embodiments, the conveying mounting frame 100 includes a mounting frame body 110, a hinge support seat 120, a walking wheel 130, a lifting telescopic cylinder 140, and a support pulley 150. One end of the mounting frame body 110 is rotatably connected to the hinge support seat 120, and the walking wheels 130 are mounted on opposite sides of the other end. The lifting telescopic cylinder 140 is mounted at the bottom of the mounting frame body 110, and the support pulley 150 is rotatably mounted at the output end of the lifting telescopic cylinder 140. It is worth mentioning that in order to enable the conveying mounting frame 100 to be placed and installed on an uneven ground, the hinge support seat 120 includes an arc-shaped frame and a hinge block. The hinge block is mounted on the arc-shaped frame. The hinge support seat 120 is rotatably connected to the mounting frame body 110 through the hinge block, and the hinge support seat 120 is supported on the uneven ground through the arc-shaped frame.

[0051] Furthermore, a sieve filter base 160 is also provided on the mounting frame body 110. A number of equidistantly spaced sieve meshes (sieve partition bars) are provided on the sieve filter base 160. The sieve filter base 160 is arranged at the input end of the conveyor belt 210, that is, the material receiving end. Through the sieve filter base 160, large pieces or foreign objects (such as packaging bags) received can be sieved out, ensuring the stability and uniformity during the conveying process.

[0052] Preferably, a cleaning mechanism 400 is also provided on the mounting frame body 110. The cleaning mechanism 400 is electrically connected to the control center. The cleaning mechanism 400 includes a driving part 410, an external air supply part, and a cleaning part 420. The driving part 410 is installed on the mounting frame body 110 to drive the cleaning part 420 to rotate. The cleaning part 420 cleans the belt surface of the conveyor belt 210. The external air supply part is connected to the cleaning part 420 through a conduit. According to the electrical signal fed back by the conveyor belt adjusting mechanism 300 to the control center, the control center controls the output power of the external air supply part, and adjusts the intensity of the air flow output by the external air supply part according to the adjusted change of the conveyor belt 210, ensuring that the accumulated matter on the belt surface can be cleaned as much as possible.

[0053] In some preferred embodiments, the driving part 410 includes a driving motor 411, a synchronous driving wheel 412, a synchronous belt 413, and a synchronous driven wheel 414. The driving motor 411 is installed on the mounting frame body 110. The synchronous driving wheel 412 is provided at the output end of the driving motor 411. The synchronous driven wheel 414 is installed on the cleaning part 420. The synchronous belt 413 is sleeved on the synchronous driving wheel 412 and the synchronous driven wheel 414. The driving motor 411 drives the cleaning part 420 to rotate, and the cleaning part 420 rotates to clean the belt surface of the conveyor belt 210.

[0054] In some preferred embodiments, the cleaning part 420 includes a cleaning air supply cylinder 421 and a cleaning brush body 422. A number of air outlet holes are provided on the cleaning air supply cylinder 421. The cleaning air supply cylinder 421 is rotatably installed on the mounting frame body 110. The cleaning brush body 422 is installed on the cleaning air supply cylinder 421. The cleaning air supply cylinder 421 is connected to the external air supply part through the conduit. The cleaning brush body 422 is a silica gel brush plate or a cleaning brush. During the cleaning process, through the air supply of the external air supply part, cleaning and blowing are achieved simultaneously, improving the cleaning strength and cleanliness.

[0055] In order to prevent the sticky coal and sticky ash from splashing everywhere and polluting the environment during the cleaning process, a cleaning baffle 170 is further provided on the mounting frame body 110.
