Description

Technical Field

[0001] This utility model relates to the field of cement production technology, specifically to a dust collection device for a cement shipping and packaging machine. Background Technology

[0002] Cement production is a complex process, mainly including raw material preparation, raw meal preparation, clinker calcination, cement grinding and packaging. During the cement production process, it is also necessary to strictly control and test the quality of each link, including raw material composition analysis, raw meal and clinker quality testing, and cement physical property testing.

[0003] With social development, the consumption of cement is increasing. During cement production, enterprises need to prioritize environmental protection and take effective measures to reduce dust emissions, treat wastewater, and comprehensively utilize waste residue to achieve sustainable development. Most existing dust collection equipment operates by direct start-up. However, in actual cement shipping operations, the bagged loading process is discontinuous, exhibiting randomness and unpredictability. Therefore, directly starting the dust collection fan system using the industrial frequency method results in continuous operation even when there are no vehicles, inevitably causing the equipment to idle for periods, leading to unnecessary power consumption. Furthermore, it prevents automatic cleaning of the dust collection components, causing a large amount of dust to accumulate on their surfaces over time, requiring manual disassembly and cleaning. This not only consumes a significant amount of time but also impacts cement production. To address these technical problems, we have designed a dust collection device for cement shipping and packaging machines. Utility Model Content

[0020] Please see Figures 1-5A dust collection device for a cement shipping and packaging machine includes a support frame 1. A dust collector 2 is embedded in the right side of the support frame 1. A main fan 5 is fixedly installed on the top left side of the support frame 1. A dividing wheel 8 is connected to the bottom of the dust collector 2. A chute pipe 9 is connected to the bottom of the dividing wheel 8. A chute fan 10 is fixedly installed at the bottom of the chute pipe 9. A packaging component 7 is arranged on the right side of the dust collector 2. A filter mechanism 11 is connected to the rear side of the main fan 5. A frequency converter 12 is fixedly installed on the rear side of the dust collector 2. A dust collection bag 3 is fixedly installed in the inner cavity of the dust collector 2. A cleaning mechanism 4 is arranged in the inner cavity of the dust collector 2. The front of the support frame 1 is fixedly... The filter mechanism 11, equipped with a PLC control module 17, includes an exhaust pipe 13 connected to the rear of the main fan 5. The cleaning mechanism 4 includes a fixed housing 18 fixedly installed on the rear of the dust collector 2. By setting a dividing wheel 8, the collected dust can be divided into sections to prevent a large amount of cement from entering the inclined chute 9. Through the cooperation of the inclined chute 9 and the inclined chute fan 10, the collected cement powder can be transported to the bucket elevator. By setting and adjusting the frequency converter 12, it can be electrically connected to the packaging drawer cabinet equipment.

[0021] Please see Figure 1 , Figure 2 and Figure 3 Positioning blocks 16 are fixedly installed on both the upper and lower sides of the inner cavity of the discharge pipe 13. A filter plate 15 is movably installed in the inner cavity of the positioning block 16. The top of the filter plate 15 extends through to the outside of the discharge pipe 13 and is fixedly connected to a fixing plate 14.

[0022] Please see Figure 1 and Figure 5 A servo motor 19 is fixedly installed on the top of the fixed housing 18, and a threaded rod 20 is fixedly installed through the output end of the servo motor 19 into the inner cavity of the fixed housing 18.

[0023] Please see Figure 1 and Figure 5 The threaded rod 20 is threaded with an air jet plate 21, which is movably fitted onto the surface of the dust collection bag 3.

[0024] Please see Figure 1 and Figure 5 A limiting plate is fixedly fitted on the surface of the threaded rod 20. The input end of the servo motor 19 is electrically connected to the PLC control module 17. By setting the limiting plate, the jet plate 21 can be limited, thereby ensuring that the jet plate 21 can be fitted on the surface of the dust bag 3.

[0025] Please see Figure 1 , Figure 2 and Figure 5An air pump 22 is fixedly installed on the rear side of the top of the support frame 1. The air outlet of the air pump 22 is connected to a telescopic hose 23. A drive motor 6 is fixedly installed on the left side of the main fan 5. The air outlet of the telescopic hose 23 is connected to the jet plate 21. By setting the telescopic hose 23, the jet plate 21 can be moved up and down.

[0026] Please see Figure 1 , Figure 2 and Figure 4 The dust collector 2 has an observation window fixed to its front by bolts. The input end of the frequency converter 12 is electrically connected to the drawer cabinet equipment via wires. The output end of the frequency converter 12 is electrically connected to the PLC control module 17. The output end of the frequency converter 12 is electrically connected to the main fan 5 via wires. The discharge end of the inclined trough pipe 9 is connected to the bucket elevator. By setting the observation window, the dust collection status inside the equipment can be viewed.

[0027] In use, the PLC control module 17 can control the equipment. When the packaging component 7 is packaging cement, the PLC control module 17 can control the equipment according to the current signal of the drawer cabinet equipment. When the packaging component 7 is discharging material, the current of the drawer cabinet equipment is greater than 20A, and the operating frequency of the main fan 5 will be maintained at 50HZ. When the packaging component 7 is idling, the current of the drawer cabinet equipment is greater than 5A and less than 20A, and the operating frequency of the main fan 5 will be maintained at 35HZ. When the packaging component 7 is in standby mode, the current of the drawer cabinet equipment is greater than 0A and less than 5A, and the operating frequency of the main fan 5 will also be maintained at 30HZ. This prevents the main fan 5 from constantly maintaining a high-speed operation and avoids the need to frequently change the operating gear of the equipment, preventing a large impact on the equipment due to rapid and frequent gear changes. The PLC control module 17 can then detect the current of the drawer cabinet equipment by adjusting the frequency converter 12 to determine the operating status of the packaging component 7, so that the PLC control module 17 can adjust the operating frequency of the main fan 5 to reduce power consumption or damage to the equipment.

[0028] During dust collection, the main fan 5 will collect cement dust into the dust collector 2 through the cleaning mechanism 4. After the cement dust enters the dust collector 2, the dust bag 3 will perform dust removal. After dust removal, the main fan 5 will introduce the remaining air into the exhaust pipe 13, so that the filter plate 15 in the exhaust pipe 13 can perform secondary filtration of the air to avoid cement dust residue in the air.

[0029] Meanwhile, during long-term use, the PLC control module 17 periodically controls the servo motor 19 and the air pump 22. The servo motor 19 drives the jet plate 21 to move up and down through the threaded rod 20. At the same time, the air pump 22 injects gas into the jet plate 21, so that the jet plate 21 can spray and clean the surface of the dust bag 3 to prevent a large amount of cement dust from adhering to the surface of the dust bag 3.

[0030] In summary, the dust collection device of this cement shipping and packaging machine, through the cooperation of support frame 1, dust collector 2, dust bag 3, cleaning mechanism 4, main fan 5, drive motor 6, packaging component 7, dividing wheel 8, inclined chute pipe 9 and inclined chute fan 10, solves the problem of the equipment running idle for part of the time, causing unnecessary power consumption, and the inability to automatically clean the surface of the dust collection components, which requires manual disassembly and cleaning by personnel, thus affecting the cement production efficiency.
