Description

Technical Field

[0001] The present invention relates to the technical field of an intelligent loading online monitoring system, in particular to an intelligent loading online monitoring system. Background Art

[0002] Cement refers to a powdered hydraulic cementitious material that is mixed with water to form a plastic slurry, which can bind materials such as sand and stone and can harden both in air and in water. It is commonly used in various construction fields and is an indispensable material in the construction industry. Cement manufacturers use pulverized coal for grinding and calcining during production, so there is a risk of dust explosions from combustible dust in the workshop. Especially during the loading and unloading process of combustible dust when it is loaded and transported to the work site, a large amount of dust is inevitably generated and suspended in the air. The loading environment is chaotic and noisy, making dust explosions very likely to occur. A dust explosion refers to a dust cloud formed by the mixing of combustible dust with air in a confined space. Under the action of an ignition source, the dust-air mixture formed quickly burns, causing a chemical reaction in which the temperature and pressure rise sharply, which is extremely dangerous. Therefore, it is necessary to test or provide early warning during the loading process to see if the dust concentration in the air reaches a dust explosion level.

[0003] Existing dust concentration monitoring devices all monitor the dust concentration in the air through various electronic sensors. The monitoring results are not only prone to deviations, but are also affected by the uniformity of the dust concentration distribution in the air, and the monitoring effect is very limited. Safety is achieved through preliminary tests or reference standards, and the dust content is used to determine whether there is a risk of dust explosion. In addition, electronic devices such as sensors are also easily affected by dust and cannot work normally. Furthermore, the results obtained from monitoring and the actual results cannot be generalized. This kind of warning with existing technology is inherently unsafe. First, whether a dust storm will occur is not only affected by dust, but also by oxygen and other flammable gases in the air. Second, it is affected by Due to the influence of temperature, the temperature difference between winter and summer reaches 20 degrees Celsius; this warning relies solely on dust content, and there are a lot of false alarms and missed alarms. In order to pursue maximum production safety, taking missed alarms as an example, there is currently a lack of effective, reliable and controllable technical measures, and there is a lack of buffered warnings at a distance or close to the dangerous value, because dust explosions do not happen overnight, and are often the result of the integration of multiple factors, such as the gradual increase in dust concentration, the lack of air flow and oxygen content to meet explosion conditions, the presence of static electricity or fire sources, and the appropriate ambient temperature, etc. Among these factors, the latitude of dust concentration and ambient temperature can be used for centralized and segmented warnings, so improvements are needed.

The limiting column 12 on the bracket disk 6 passes through the threaded hole 18 on the extrusion sliding disk 7.

A torsion plate 19 is rotatably mounted at the center of both side surfaces of the extrusion sliding disk 7. A torsion spring is provided between the torsion plate 19 and the extrusion sliding disk 7. One end of the torsion spring is fixedly connected to the center of the extrusion sliding disk 7, and the other end of the torsion spring is fixedly connected to the center of the torsion plate 19. An initiating piece 8 is provided on the initiating piece 8. The initiating piece 8 is made of piezoelectric ceramics and can impact the electrode 11.

[0079] The ends of the limiting column 12 and the electrode 11 on the bracket disk 6 are in contact with the buffer plate 13, and the buffer plate 13 is provided with a groove, and the ends of the limiting column 12 and the electrode 11 are both extended into the groove; a gear ring is installed on the bracket disk 6 through a bearing, and the gear ring is engaged with the planetary gear 14 on the bracket disk 6, and a burst detection chamber 9 is rotatably installed on the buffer plate 13, one end of the burst detection chamber 9 is in contact with the buffer plate 13, and the other end of the burst detection chamber 9 is fixedly connected to the gear ring; the inner diameter of the burst detection chamber 9 is the same as the inner diameter of the extrusion sliding disk 7; a plurality of ventilation holes are provided at both ends of the burst detection chamber 9; a plurality of straight grooves are evenly distributed in the burst detection chamber 9, and a trigger point 10 is installed in the straight groove. The trigger point 10 can be squeezed into the straight groove by the extrusion sliding disk 7, and the trigger point 10 can push the detonating piece 8 to rotate;

[0080] The sun gear 15 on the bracket disk 6 is driven by the power module 2, and the power module 2 is fixedly mounted on the bracket; a limit rod is provided between the bracket and the fixed rod; a sealing cylinder is provided on the outer cover of the explosion detection chamber 9, and a limit hole is provided on the outside of the sealing cylinder, through which the limit rod passes; an external thread is provided in the middle of the outer surface of the explosion detection chamber 9, and an internal thread is provided in the middle of the inner surface of the sealing cylinder, which can engage with the external thread; washers are provided at both ends of the inner surface of the sealing cylinder, which can seal the air hole 26.

[0081] Example 13

[0082] The working process is as follows:

[0083] The power module 2 is started, driving the sun gear 15 to rotate, and the planetary gear 14 and the ring gear rotate accordingly; the planetary gear 14 rotates, driving the limit column 12 to rotate, and the limit column 12 drives the extrusion sliding disk 7 to move from left to right; the ring gear rotates, that is, the explosion detection chamber 9 rotates. On the one hand, the explosion detection chamber 9 will drive the blocking cylinder to move to the right by rotating to block the air hole 26 on the right side. On the other hand, the explosion detection chamber 9 will continuously fluctuate the detonating piece 8 through the trigger point 10 during the rotation process, causing the detonating piece 8 to swing, thereby giving the torsion spring between the torsion swing plate 19 and the extrusion sliding disk 7 a force. The power is stored and then released, causing the detonating piece 8 to impact the electrode 1 11. The current generated by the impact between the detonating piece 8 and the electrode 1 11 is released through the electrode 2 17 on the impact plate, igniting the space on the right side of the extrusion sliding disk 7, and detonating the test; the power module 2 continues to rotate, and after the sealing plate blocks the air hole 26 on the explosion detection chamber 9, the extrusion sliding disk 7 gradually compresses the gas and dust in the right space during its movement from left to right, and detonating tests are continuously carried out to determine the approximate concentration and safety range of the gas and dust concentration on site;

[0084] After the extrusion sliding disk 7 moves to the rightmost end or moves to the point where it cannot move, the power module 2 reverses, and the blocking cylinder moves from right to left to block the air hole 26 on the left side of the explosion detection chamber 9. At the same time, the extrusion sliding disk 7 starts to move from right to left to compress and detonate the space on the left side; and the air hole 26 on the right side opens, and fresh air begins to gather from the right side into the explosion detection chamber 9, ensuring that the gas in each test is fresh gas in the space to be detected, so that the next operation can be carried out.

[0085] Example 14

[0086] Further implementation of the present application can be implemented by adopting the following lower-level technical features: the power module is a motor, the drainage module is a water outlet valve, the injection module is a water inlet valve, the bracket plate is a fixed frame, the extrusion sliding plate is a sliding plate, the detonating piece is an impact piece, the explosion detection chamber is a rotating drum, the trigger point is a shrapnel, the electrode one is a piezoelectric ceramic rod, the limiting column is a screw, the electrode two is a phosphor copper sheet, and the sealing column chamber is an arc groove.

[0087] Example 15

[0088] Taking pulverized coal as an example, during a certain unloading process, the real-time measurement results are as follows:

[0089] The dust concentration on site is set to an initial proportional value X, and the ambient temperature is T;

[0090] The following measurements are constant temperature measurements:

[0091] Measuring the burst temperature Dust concentration ratio (compression ratio) Explosion T X no T 1.2X no T 1.4X yes

[0092] The following is the temperature change (temperature increase) determination, the following table;

[0093] Measuring the burst temperature Dust concentration ratio (compression ratio) Explosion T+2 X no T+4 X yes

[0094] Further consideration could be given to setting different conditions for all tests. This could yield safe thresholds or the risk associated with factors affecting the current proximity to a dust explosion. For example, if the temperature is expected to rise significantly at noon and control measures are needed, or if ventilation is poor and dust concentrations are likely to increase, posing a dust explosion risk, compared to sensors that rely on temperature and dust concentration measurements, this method uses real-time, pre-determined variable conditions to determine dust explosion risk, resulting in reliable results, ease of use, and improved safety. This method can generate dust explosion temperature and concentration curves. Of course, this application is not limited to such measurements or tests. The key point is that it uses on-site dust. When other combustible dusts are mixed with the dust, traditional temperature and concentration measurements to predict dust explosion warnings become unreliable. This application, however, uses on-site dust for measurement, resulting in a short delay and a minimum sampling interval of approximately 5 minutes. The measurement results are close to on-site conditions, eliminating uncontrollable risks such as the mixing of certain gases or dusts without adequate dust monitoring. By using on-site measurements and explosion detection, these hidden risks are completely eliminated.

[0095] Example 16

[0096] In order to shorten the waiting time during the temperature adjustment process, this application records the structure of the temperature adjustment process during use;

[0097] The main purpose is to compare the time required for the temperature to stabilize when the heat-conducting pillar 24 of the present application dynamically adapts to heating and cooling, and to compare it with the time required when the heat-conducting pillar 24 of the present application does not have this structure. The heat-conducting pillar 24 is operated continuously, and the time required for the explosion chamber to reach the ambient temperature is measured.

[0098] Measuring temperature changes in the explosion chamber No thermal columns or storage structures Exposed thermal conductive pillars Wrapped thermal conductive column Cooling (compression 20%) 2 minutes 1.3 minutes none Cooling (compression 40%) 6 minutes 3 minutes none Cooling (compression 60%) 16 minutes 7 minutes none 2°C temperature rise 3 minutes none 3 minutes Temperature rise of 4°C 7 minutes none 6 minutes Temperature rise of 6°C 10 minutes none 8 minutes After the explosion, it stabilizes to the ambient temperature 3 1 minute none

[0099] It can be seen that the use of the movable heat-conducting column structure of the present application reduces the time required for heat dissipation and has little effect on the heat absorption or temperature rise process.
