Technical Field

[0001] The invention belongs to the technical field of transportation, and in particular relates to a quick transportation device for coal in a power plant. Background Art

[0002] Power plants generally use thermal power generation, that is, using coal as power. Although there are existing technologies for using new energy sources for power generation, such as wind power generation and solar power generation, they have not yet been widely popularized, and thermal power generation still dominates the market.

[0003] When thermal power generation is adopted, the coal piled outside needs to be transported to the combustion section for combustion. In order to promote more complete combustion of the coal, large pieces of coal need to be crushed and then transported to the combustion section for combustion. Although the existing conveying equipment has the function of crushing and screening materials, it cannot control the particle size of the crushed materials according to the mass of the materials piled on the screen plate, resulting in the accumulation of materials in the screening section, which seriously affects the material conveying efficiency.

[0016] A method for using the above-mentioned power plant coal quick transportation equipment comprises the following steps:

[0017] S1. Start the two first electric rollers to drive the conveyor belt to transmit. At this time, the first electric roller drives the driving disk to rotate in the vertical direction. The driving disk pushes the legs to perform linear reciprocating motion in the vertical direction along the sliding cavity through the second elliptical slide rail. The legs push the mounting frame to drive the screen plate to vibrate, and the coal crushed by the crushing mechanism is screened. The screened coal falls onto the conveyor belt for transportation and processing;

[0018] S2. The second pressure sensor obtains the total mass of the coal on the screen plate. If the total mass exceeds the preset mass threshold, the second linear motion member is activated to retract the support block into the placement slot, so as to cause the slide column slidably arranged in the second elliptical slide rail to slide into the first elliptical slide rail, that is, to increase the displacement distance of the support leg, thereby achieving the technical effect of increasing the amplitude of the screen plate;

[0019] S3, the second pressure sensor transmits the acquired data to the external controller, which analyzes the acquired coal mass data on the screen plate to obtain the coal mass increase rate. If the coal increase rate exceeds the preset coal increase rate threshold, the first linear motion member is started to push the slider to drive the second electric roller shaft installed on the slider to perform linear motion, so as to reduce the distance between the two crushing rollers and reduce the coal crushing particle size;

[0020] S4, the external controller obtains the temperature of the liquid in the first liquid cavity detected by the temperature sensor, obtains the friction between the square tube and the sliding cavity, and compares the obtained friction information, temperature information and coal mass increase rate information with the preset friction threshold, temperature threshold and mass increase rate threshold. If they exceed the corresponding thresholds, the lubrication component, liquid cooling component and the first linear motion component are started to adjust the temperature, friction and coal mass increase rate, so that the three are within the corresponding thresholds;

[0021] S5. Analyze the friction information, temperature information and coal mass increase rate obtained in S4 by linear regression to obtain the friction prediction value, temperature prediction value and coal mass increase rate prediction value, and compare the three prediction values ​​with the friction threshold, temperature threshold and coal mass increase rate threshold. If they exceed the corresponding thresholds, control information for controlling the lubrication component, the liquid cooling component and the first linear motion component is formed to reduce the friction, temperature and coal mass increase rate.

[0022] S6. The temperature prediction value, friction prediction value and coal mass increase prediction value obtained in S5 are dimensionlessly processed and then associated to form a control condition coefficient. If the control condition coefficient exceeds a preset control condition coefficient threshold, the lubrication component, the cooling component and the first linear motion component are started to reduce the friction, temperature and coal mass increase rate, so that the control condition coefficient is within the control condition coefficient threshold. The association model of the control condition coefficient is:

[0025] The present invention provides a quick coal transportation device for a power plant, which has the following beneficial effects compared with the prior art:

[0026] 1. In the present invention, two second electric roller shafts drive the crushing rollers fixedly connected thereto to perform a rotational movement in the opposite direction of the vertical movement, so as to crush the coal blocks placed in the crushing box. The crushed crushing box reaches the sieve plate on the sieve plate mechanism through the opening at the bottom of the crushing box, and at the same time, the first electric roller shaft is started to drive the conveyor belt to transport the coal blocks screened by the sieve plate mechanism. At the same time, the first electric roller shaft drives the driving disk to rotate, and the driving disk drives the sliding column to drive the support leg to perform a linear reciprocating movement in the vertical direction along the machine table through the second elliptical slide rail, that is, drives the mounting frame to push the sieve plate to vibrate, so as to screen the coal blocks on the sieve plate. At this time, the second pressure sensor detects the coal blocks that do not meet the size standards accumulated on the sieve plate. The coal blocks are weighed. If the mass of the accumulated coal blocks exceeds the preset mass threshold, the second linear motion part is started to shrink the support block into the placement slot, causing the sliding column sliding in the second elliptical slide rail to slide into the first elliptical slide rail, that is, the displacement distance of the support leg is increased, thereby achieving the technical effect of increasing the amplitude of the screen plate. When relevant technical personnel obtain the rate of increase of the mass of the coal on the screen plate by analyzing the second pressure sensor, if the rate of increase of the mass of the coal exceeds the threshold of the rate of increase of the mass of the coal, the first linear motion part is started to push the slider to drive the second electric roller shaft installed on the slider to perform linear motion, thereby reducing the distance between the two crushing rollers, reducing the particle size of the coal, and thereby improving the coal screening efficiency and the coal transportation efficiency.

If the coal increase rate exceeds a preset coal increase rate threshold, the first linear motion member (305) is started to push the slider (304) to drive the second electric roller (302) installed on the slider (304) to perform linear motion, thereby reducing the distance between the two crushing rollers (303) and reducing the coal crushing particle size; S4, the external controller obtains the temperature of the liquid in the first liquid cavity (703) detected by the temperature sensor, obtains the friction force between the square tube (403) and the sliding cavity, and compares the obtained friction force information, temperature information and coal mass increase rate information with the preset friction force threshold, temperature threshold and mass increase rate threshold. If they exceed the corresponding thresholds, the lubrication component (6), the liquid cooling component (7) and the first linear motion component (305) are started to adjust the temperature, friction force and coal mass increase rate so that the three are within the corresponding thresholds; S5, analyzing the friction information, temperature information and coal mass increase rate obtained in S4 by means of linear regression to obtain a friction prediction value, a temperature prediction value and a coal mass increase rate prediction value, and comparing the three prediction values ​​with the friction threshold, the temperature threshold and the coal mass increase rate threshold. If they exceed the corresponding thresholds, corresponding control information for controlling the lubrication component (6), the liquid cooling component (7) and the first linear motion component (305) is formed to reduce the friction, temperature and coal mass increase rate; S6, the temperature prediction value, friction prediction value and coal mass increase prediction value obtained in S5 are dimensionlessly processed and then associated to form a control condition coefficient. If the control condition coefficient exceeds a preset control condition coefficient threshold, the lubrication component (6), the cooling component and the first linear motion component (305) are started to reduce the friction, temperature and coal mass increase rate, so that the control condition coefficient is within the control condition coefficient threshold. The association model of the control condition coefficient is: Among them, K(T,F,V) represents the control condition coefficient, T t,i represents the predicted temperature value at time t, F t,i represents the predicted value of friction force at time t, V t,i The predicted value of the coal mass increase rate, n represents the same number of the temperature prediction value, the friction prediction value and the coal mass increase rate prediction value obtained up to time t.
