Description

Technical Field

[0001] This invention relates to the field of transport machinery technology, and in particular to a smart belt transport method and equipment for coal-fired power plants. Background Technology

[0002] A coal-fired power plant is a thermal power plant that uses coal as fuel to produce electricity. Its basic production process is as follows: when the fuel is burned, it heats water to generate steam, which converts the chemical energy of the fuel into thermal energy. The steam pressure drives the turbine to rotate, converting the thermal energy into mechanical energy. Then, the turbine drives the generator to rotate, converting the mechanical energy into electrical energy. Coal is a traditional resource in my country and is widely used. Therefore, it is necessary to transport sections of coal to the required locations.

[0003] In existing segmented coal transport, conveyor belts are commonly used. When using this belt, the coal needs to be transported to different heights, so the conveyor belt needs to be adjusted accordingly. However, when the conveyor belt is raised, the coal blocks in the segment are transported downwards due to their excessive weight, resulting in a faster descent speed and coal scattering, which poses a safety hazard. Therefore, controlling the weight of the coal within the segment is particularly important. Hence, there is a special need for an intelligent belt conveyor for coal-fired power plants. Summary of the Invention

[0004] The purpose of this invention is to provide a belt conveyor method and conveyor for use in coal-fired power plants. When coal is being transported, excessive local weight and tilting can cause the coal to slide down at a high speed under the influence of gravity, resulting in coal scattering and safety hazards. Therefore, controlling the amount of coal in a section is a particularly important issue.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A method for intelligent belt conveyor transport in a coal-fired power plant includes an intelligent transport mechanism installed at the bottom of the conveyor belt. Using the intelligent transport mechanism, operators can start the machine via a control panel and adjust the conveyor belt to the desired height using an electric lifting rod. A section of coal is placed above the conveyor belt. At the start of transport, the weight of the coal section is transferred by the conveyor belt to the top of the intelligent control housing. An embedded pressure sensor in the intelligent control housing transmits data to a programmable controller when the weight of the coal section is excessive. The programmable controller then controls a rotary motor to stop via a second connection line, halting the conveyor belt's operation. When the weight of the coal section returns to normal, the programmable controller restarts the rotary motor, which in turn controls a rolling shaft to rotate, driving the conveyor belt to resume transport, thus completing the intelligent transport of the conveyor belt.

[0006] The belt conveyor used in the coal-fired power plant includes a conveyor belt (1) and an intelligent transport mechanism (2). The intelligent transport mechanism (2) includes an auxiliary rolling shaft (201), a support frame (202), an intelligent control housing (203), an editable controller (204), a pressure sensor (205), a first connecting line (206), an electric lifting rod (207), a second connecting line (208), a rotary motor (209), a rolling shaft (210), and a control panel (211).

The conveyor belt (1) is connected to the auxiliary rolling shaft (201), and the auxiliary rolling shaft (201) is connected to the support frame (204). 202), the support frame (202) is connected to the intelligent control housing (203), the intelligent control housing (203) contains an editable controller (204), the editable controller (204) is connected to a pressure sensor (205), the editable controller (204) is connected to a first connecting line (206), the first connecting line (206) is connected to an electric lifting rod (207), the editable controller (204) is connected to a second connecting line (208), the second connecting line (208) is connected to a rotary motor (209), the rotary motor (209) is connected to a rolling shaft (210), and the editable controller (204) is electrically connected to a control panel (211).

The auxiliary rolling shaft (201) is symmetrically arranged relative to the central axis of the conveyor belt (1). The intelligent control housing (203) is threadedly connected to the support frame (202).

Beneficial effects

The conveyor belt is adjusted to the desired height via the electric lifting rod, and the coal block is placed above the conveyor belt. At the start of transport, the weight of the coal block is transferred to the top of the intelligent control housing. An embedded pressure sensor in the intelligent control housing detects excessive weight and transmits the data to the programmable controller.

When the weight of the coal block returns to normal, the programmable controller resumes operation, controlling the rotary motor to rotate the rolling shaft, which in turn drives the conveyor belt to begin transport, thus completing the intelligent transport function of the conveyor belt.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0013] A belt conveyor for use in a coal-fired power plant includes a conveyor belt 1 and an intelligent transport mechanism 2. The intelligent transport mechanism 2 includes an auxiliary rolling shaft 201, a support frame 202, an intelligent control housing 203, an editable controller 204, a pressure sensor 205, a first connecting line 206, an electric lifting rod 207, a second connecting line 208, a rotary motor 209, a rolling shaft 210, and a control panel 211. The intelligent transport mechanism 2 is installed at the bottom end of the conveyor belt 1.

[0014] Furthermore, the intelligent transport mechanism 2 includes an auxiliary rolling shaft 201, a support frame 202, an intelligent control housing 203, an editable controller 204, a pressure sensor 205, a first connecting line 206, an electric lifting rod 207, a second connecting line 208, a rotary motor 209, a rolling shaft 210, and a control panel 211. The bottom end of the conveyor belt 1 is connected to the auxiliary rolling shaft 201, and the bottom end of the auxiliary rolling shaft 201 is connected to the support frame 202. The top end of the support frame 202 is screwed to the intelligent control housing 203. The intelligent control housing 203 contains an editable controller 204, and the top end of the editable controller 204 is connected to the pressure sensor 205. The internal connection of 204 is a first connecting line 206, one end of which is connected to an electric lifting rod 207. One end of the programmable controller 204 is connected to a second connecting line 208, one end of which is connected to a rotary motor 209. One end of the rotary motor 209 is connected to a rolling shaft 210. One end of the programmable controller 204 is connected to a control panel 211. When using the intelligent transport mechanism 2, the operator can start the machine through the control panel 211 and adjust the conveyor belt to the required height via the electric lifting rod 207. The section coal block is placed above the conveyor belt. When the transport begins, the weight of the section coal block will be transferred to the top of the intelligent control housing 203 via the conveyor belt. A pressure sensor 205 is embedded in the upper part of the intelligent control housing 203. When the pressure sensor 205 detects that the weight of the coal block in the section is too heavy, it will transmit the data to the programmable controller 204. The programmable controller 204 will control the rotary motor 209 to stop through the second connection line 208, so that the conveyor belt stops working. When the weight of the coal block in the section returns to normal, the programmable controller 204 controls the rotary motor 209 to work. The rotary motor 209 controls the rolling shaft 210 to roll. The rolling shaft 210 drives the conveyor belt 1 of the conveyor to start transporting, thereby completing the intelligent transport function of the conveyor belt.

[0015] Furthermore, the auxiliary rolling shaft 201 is movably connected to the conveyor belt 1. The auxiliary rolling shaft 201 is symmetrically arranged about the central axis of the conveyor belt 1, which can assist the conveyor belt 1 in normal operation.

[0016] Furthermore, the intelligent control housing 203 is connected to the support frame 202 by screws, and the intelligent control housing 203 is provided with two sets of screws at the top of the support frame 202 to enhance the stability of the intelligent control housing 203.

[0017] Furthermore, the programmable controller 204 and the pressure sensor 205 are connected by wires. The programmable controller 204 and the pressure sensor 205 are sized to match, which facilitates the pressure sensor 205 to transmit data to the programmable controller 204.

[0018] Furthermore, the conveyor belt 1 of the transport machine forms a lifting structure with the support frame 202 via the electric lifting rod 207. The electric lifting rod 207 and the support frame 202 are connected by screws, which allows the height of the conveyor belt 1 to be freely adjusted.

[0019] Furthermore, the rolling shaft 210 forms a rotating structure with the conveyor belt 1 of the conveyor via the rotary motor 209. The rolling shaft 210 and the rotary motor 209 are movably connected, which can drive the section of coal blocks to move forward.

[0020] Working Principle: When the device is needed, it is first placed in the required position. The operator can start the machine via control panel 211 and adjust the conveyor belt to the desired height using electric lifting rod 207. The next step is to place the coal block section above the conveyor belt. At the start of transport, the weight of the coal block section is transferred to the top of the intelligent control housing 203. A pressure sensor 205 is embedded in the intelligent control housing 203. When the pressure sensor 205 detects that the weight of the coal block section is too high, it transmits the data to the programmable controller 204. The programmable controller 204 then controls the rotary motor 209 to stop via the second connection line 208, thus stopping the conveyor belt. When the weight of the coal block section returns to normal, the programmable controller 204 controls the rotary motor 209 to operate. The rotary motor 209 controls the rolling shaft 210 to rotate, which in turn drives the conveyor belt 1 to begin transporting the coal. This completes the operation of a belt conveyor used in a coal-fired power plant.
