Description

Technical Field

[0001] The present application relates to the technical field of conveying devices, and particularly to an intelligent belt conveyor with a drying function. Background Art

[0002] In the preparation of coal samples, the coal samples will be dried, and the drying has two functions: 1. Remove part of the moisture in the coal samples so that they can smoothly pass through crushers and riffle splitters, avoiding sticking, blocking, and residue caused by high humidity, which may affect the representativeness of the coal samples; 2. The coal samples need to reach the air-dried state (close to equilibrium with the surrounding atmospheric humidity) to minimize the moisture change of the coal samples during the chemical analysis process and ensure the accuracy and precision of the analysis test results.

[0003] However, it takes up to 24 hours for coal samples to air-dry naturally to reach the air-dried state at an ambient temperature of 20°C. To improve the drying efficiency, equipment such as drying ovens is used for rapid drying. In existing sample preparation systems, the drying function is often set in a specific drying device and is connected in series with other processes in the system. Even though the drying device improves the drying efficiency, the drying process still has a great impact on the sample preparation efficiency. Since too high drying temperature (greater than 50°C) will cause the oxidation of coal samples, resulting in changes in sample characteristics and affecting the test results. Therefore, it is difficult to improve the efficiency of a single drying machine. Thus, there is an urgent need to study a drying device that can improve the drying efficiency from the perspective of the entire sample preparation system, thereby improving the overall efficiency of the sample preparation system. Summary of the Utility Model

[0004] To address the problem of low efficiency and the risk of oxidizing coal samples in the application of existing drying equipment during the drying process of coal samples, the present application provides an intelligent belt conveyor with a drying function.

[0005] The intelligent belt conveyor with a drying function provided by the present application adopts the following technical solutions:

[0006] An intelligent belt conveyor with a drying function includes a base and a conveyor belt, and further includes the following components arranged in sequence along the conveying direction of the conveyor belt:

[0007] A coal flow sensing device for monitoring the coal flow on the conveyor belt;

[0008] A rectifying device for rectifying, loosening, and spreading the coal samples on the conveyor belt;

[0009] A heating module for heating the loose coal samples on the conveyor belt; and

[0010] A controller, electrically connected to the coal flow sensing device, the rectifying device, and the heating module, and configured to control the rectifying device and the heating module to start only when the coal flow sensing device detects a coal sample on the conveyor belt, and to control the rectifying device and the heating module to delay closing when the coal flow sensing device detects no coal sample on the conveyor belt.

[0011] Furthermore, the rectifying device includes:

[0012] Guide rails, arranged along the conveying direction of the conveyor belt;

[0013] Sliders, slidably arranged on the guide rails;

[0014] Rake plates, fixedly connected to the sliders and arranged orthogonally to the guide rails; and

[0015] A driving mechanism for driving the sliders to reciprocate on the guide rails.

[0016] Furthermore, the driving mechanism includes:

[0017] A driving motor, installed on the base and located directly above the conveyor belt;

[0018] A crank, with one end fixedly connected to the output end of the driving motor;

[0019] A connecting rod, with one end hinged to the free end of the crank and the other end hinged to the rake plate.

[0020] Furthermore, there are two groups of the guide rails and the sliders arranged on both sides of the rake plate.

[0021] Furthermore, an arc-shaped notch is formed at the bottom of the rake plate, and the arc-shaped notch and the belt surface of the conveyor belt form a rectifying channel for the coal flow to pass through.

[0022] Furthermore, overflow ports are arranged on both sides of the arc-shaped notch of the rake plate, and the overflow ports and the belt surface of the conveyor belt form an overflow channel for the excess coal flow to pass through.

[0023] Furthermore, a plurality of through holes are formed through the upper part of the rake plate, and the through holes are long holes and arranged in the vertical direction.

[0024] Furthermore, multiple groups of the heating module are arranged on the side of the rectifying device away from the coal flow sensing device.

[0025] Furthermore, the heating module is an infrared heating device.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. After the belt conveyor of the present application is started, the coal sample is fed into the conveyor belt from the front-end component. When the coal flow sensing device detects the presence of coal flow on the conveyor belt, the controller controls the rectifying device to act, rectifying the coal flow into a uniform and loose state; at the same time, the controller controls the heating module to start synchronously to heat and dry the rectified coal; until the coal flow sensing device detects that there is no coal sample on the conveyor belt, the rectifying device and the heating module stop working after a delay for a period of time, and the coal sample on the conveyor belt can be automatically dried;

[0028] 2. Based on the original conveying basic function of the belt conveyor of the present application, the drying work is completed at the same time. Replacing the belt conveyor of the existing sample preparation system with the belt conveyor of the present application enables the coal sample to be dried while being conveyed in each link. In this way, a distributed drying system is built in the processes such as reduction and transfer before and after drying, making the drying form a parallel connection with other links in the system and running simultaneously, greatly reducing the pressure on the original drying equipment and improving the overall efficiency of the drying system.

[0040] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] Refer to Figure 1 and Figure 2 , the embodiments of the present application disclose an intelligent belt conveyor with a drying function, which includes a base 11 and a conveyor belt 12. The conveyor belt 12 is installed on the base 11, and further includes components installed on the base 11 and arranged in sequence along the conveying direction of the conveyor belt 12:

[0042] A coal flow sensing device 2 for monitoring the coal flow on the conveyor belt 12, which can specifically be an infrared rangefinder, or a flap hinged to the base 11 and a pressure sensor installed on the base 11. When the flap is flipped under the push of the coal flow, it touches the pressure sensor arranged on the base 11;

[0043] A rectifying device 3 for rectifying, loosening and dispersing the coal sample on the conveyor belt 12;

[0044] A heating module 4 for heating the loose coal sample on the conveyor belt 12. The heating module 4 is an infrared heating device or other feasible ones; and

[0045] A controller, which is electrically connected to the coal flow sensing device 2, the rectifying device 3 and the heating module 4, and is configured to control the rectifying device 3 and the heating module 4 to start only when the coal flow sensing device 2 detects that there is a coal sample on the conveyor belt 12, and to control the rectifying device 3 and the heating module 4 to delay closing when the coal flow sensing device 2 detects that there is no coal sample on the conveyor belt 12.

[0046] After such a setting, when the belt conveyor of the present application is started, the coal sample is input into the conveyor belt 12 from the front-end component. When the coal flow sensing device 2 detects the presence of coal flow on the conveyor belt 12, the controller controls the rectifying device 3 to act to rectify the coal flow into a uniform and loose state; at the same time, the controller controls the heating module 4 to start synchronously to heat and dry the rectified coal; until the coal flow sensing device 2 detects that there is no coal sample on the conveyor belt 12, the rectifying device 3 and the heating module 4 work for a period of time with a delay and then stop working.

[0047] With the above settings, on the basis of the original conveying function, the belt conveyor of the present application also completes the drying work. By replacing the belt conveyor of the existing sample preparation system with the belt conveyor of the present application, the coal sample is dried while being conveyed in each link. In this way, a distributed drying system is built in the processes of sample reduction, transfer, etc. before and after drying, so that drying and other links in the system form a parallel connection and operate simultaneously, greatly reducing the pressure on the original drying equipment and improving the overall efficiency of the system.

[0048] In addition, to further improve the conveying effect of the coal sample when it is conveyed on the conveyor belt 12, multiple groups of heating modules 4 are arranged on the side of the rectifying device 3 away from the coal flow sensing device 2, so that the coal sample can be dried throughout the conveying process in the belt conveyor of the present application.

[0049] Moreover, referring to Figure 3 and Figure 4 , the above-mentioned rectifying device 3 includes:

[0050] A guide rail 31, arranged along the conveying direction of the conveyor belt 12;

[0051] A slider 32, slidably arranged on the guide rail 31;

[0052] A rake plate 33, fixedly connected to the slider 32 and arranged orthogonally to the guide rail 31, and two groups are arranged on both sides of the rake plate 33 with the guide rail 31 and the slider 32; and

[0053] A driving mechanism, used to drive the slider 32 to reciprocate on the guide rail 31.

[0054] Among them, the driving mechanism includes:

[0055] A driving motor 341, installed on the base 11 and located directly above the conveyor belt 12, and the output end of the driving motor 341 is arranged orthogonally to the conveying direction of the conveyor belt 12;

[0056] A crank 342, with one end fixedly connected to the output end of the driving motor 341;

[0057] A connecting rod 343, with one end hinged to the free end of the crank 342 and the other end hinged to the rake plate 33.

[0058] In addition, an arc-shaped notch 51 is opened in the middle area at the bottom of the rake plate 33, and the arc-shaped notch 51 and the belt surface of the conveyor belt 12 form a rectifying channel 52 for the coal flow to pass through; overflow ports 53 are arranged on both sides of the rake plate 33 at the arc-shaped notch 51, and the overflow ports 53 and the belt surface of the conveyor belt 12 form an overflow channel 54 for the excess coal flow to pass through; and a plurality of through holes 55 are formed through the upper part of the rake plate 33, and the through holes 55 are long holes and are arranged in the vertical direction.

[0059] After such setting, when the rectifying device 3 works, the driving motor 341 drives the crank 342 to rotate with the axis of its output end as the rotation axis. During the rotation of the crank 342, the rake plate 33 is pulled by the connecting rod 343, and the two sliders 32 respectively make reciprocating motions on the two guide rails 31, so that the reciprocating motion of the rake plate 33 along the conveying direction of the conveyor belt 12 can be realized; when the rake plate 33 makes a reciprocating motion, the coal sample on the conveyor belt 12 can be leveled, and the coal sample can be rectified into a uniform and loose state for drying. Among them, the setting of the rectifying channel 52 can ensure the overall shape consistency of the coal sample on the conveyor belt 12 to ensure the uniform drying effect of the coal sample; the setting of the overflow channel 54 facilitates the excess coal sample to quickly pass through the rake plate 33, avoiding the coal sample being pushed out of the conveyor belt 12 when the relative speed between the rake plate 33 and the coal sample is too large; the setting of the through holes 55 also facilitates the coal sample piled up too high to quickly pass through the rake plate 33, reducing the probability of the piled-up coal sample on the conveyor belt 12 scattering everywhere.

[0060] The implementation principle of an intelligent belt conveyor with a drying function according to an embodiment of the present application is as follows:

[0061] After the belt conveyor of the present application is started, the coal sample is put into the conveyor belt 12 from the front-end component. When the coal flow sensing device 2 detects the presence of coal flow on the conveyor belt 12, the controller controls the rectifying device 3 to act to rectify the coal flow into a uniform and loose state; at the same time, the controller controls the heating module 4 to start synchronously to heat and dry the rectified coal; until the coal flow sensing device 2 detects that there is no coal sample on the conveyor belt 12, the rectifying device 3 and the heating module 4 stop working after delaying for a period of time.

[0062] With the above settings, on the basis of the original conveying function, the belt conveyor of the present application simultaneously completes the drying work. Replacing the suitable belt conveyor of the existing sample preparation system with the belt conveyor of the present application enables the coal sample to be dried while being conveyed in each link. In this way, a distributed drying system is built in the processes such as reduction and transfer before and after drying, making the drying form a parallel connection with other links in the system and running simultaneously, greatly reducing the pressure on the original drying equipment and improving the overall efficiency of the system.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
