[0003] However, the device has certain shortcomings in use. It is not easy to adjust and control the collection and treatment of dust, and it is easy to generate dust. Utility Model Content

[0004] The purpose of this solution is to provide a solid waste separation device for lime production to solve the problem that the device is not easy to adjust and control to collect and treat dust, and is prone to generating dust.

[0005] To achieve the above objectives, this solution provides a solid waste separation device for lime production, including a kiln-under-kiln lime dust collector. The kiln-under-kiln lime dust collector is equipped with a pneumatic conveying pipeline. A kiln-under-kiln lime dust collection valve is located in the middle of the pneumatic conveying pipeline. A centralized ash collection tank is installed on the pneumatic conveying pipeline. A transfer station lime dust collector pneumatic conveying pipeline is installed on the centralized ash collection tank. A transfer station lime dust collection valve is located in the middle of the pneumatic conveying pipeline. A kiln-under-kiln lime dust collector pneumatic conveying pipeline is also provided. The newly modified pneumatic conveying pipeline for the ash dust collector includes a lime powder silo in a screening tower. A pipe reducer is installed on the newly modified pneumatic conveying pipeline for the lime dust collector under the kiln. The pipe reducer and the pneumatic conveying pipeline for the lime dust collector at the transfer station are connected by the newly modified pneumatic conveying pipeline for the lime dust collector at the transfer station. A second pipe switching valve and a first pipe switching valve are installed in the middle of the newly modified pneumatic conveying pipeline for the lime dust collector at the transfer station. A lime dust collector for the transfer station is installed at the end of the pneumatic conveying pipeline for the lime dust collector at the transfer station.

[0006] The principle of this solution is as follows: During use, the suction pump draws air from the lower end of the support plate, creating a negative pressure in the lower part of the housing. This causes the sealing plate to move upwards, separating it from the cone. During this process, the sealing plate moves the connecting rod upwards, which in turn moves the baffle to compress the spring. This compression allows the airflow to carry dust into the housing, where it is filtered by the filter. The suction pump creates a negative pressure in the lower part of the housing, separating the sealing plate from the cone, allowing dust to enter the housing. The spring then resets the sealing plate, sealing the upper end of the cone to prevent dust backflow. The filter filters the dust, and the airflow drives the fan blades to rotate the support shaft. This causes the square rod to rotate the scraper blades via the slip ring, causing the scraper blades to scrape against the filter, preventing clogging and ensuring efficient dust filtration.

[0007] The technical effect of this solution is that the suction pump creates a negative pressure at the bottom of the housing, causing the sealing plate and the cone to separate, allowing dust to enter the housing. The spring then resets the sealing plate, sealing the top of the cone and preventing dust backflow.

[0008] Dust is filtered through a screen, and the airflow drives the fan blades to rotate the support shaft. This causes the square rod to rotate the scraper through the slip ring, which in turn causes the scraper to rub against the screen, making the screen less prone to clogging and ensuring dust filtration efficiency.

[0009] Furthermore, the lime dust collector at the transfer station includes a base, which is fixedly connected to the pneumatic conveying pipeline of the lime dust collector under the kiln. A shell is threadedly connected to the outer side of the base. A cone is fixedly connected to the upper end of the base. A support ring is fixedly connected inside the cone. A connecting rod is slidably connected inside the support ring. A sealing plate is fixedly connected to the upper end of the connecting rod. A baffle is fixedly connected to the lower end of the connecting rod. A spring is provided on the outer side of the connecting rod. A filter screen is fixedly connected inside the shell. A support shaft is installed inside the filter screen via a bearing. A square rod is fixedly connected to the lower end of the support shaft. A limit plate is fixedly connected to the lower end of the square rod. A slip ring is slidably connected to the outer side of the square rod. A compression spring is provided on the outer side of the square rod. A scraper is fixedly connected to the surface of the slip ring. A fan blade is fixedly connected to the outer side of the support shaft. A support plate is fixedly connected inside the shell. A suction pump is fixedly installed in the middle of the upper end of the support plate. The suction pump creates negative pressure at the bottom of the housing, causing the sealing plate and cone to separate, allowing dust to enter the housing. A spring then resets the sealing plate, sealing the top of the cone to prevent dust backflow. The dust is filtered through a screen, and airflow drives the fan blades to rotate the support shaft. This, in turn, causes the square rod to rotate the scraper blades via a slip ring. The scraper blades then scrape against the screen, preventing clogging and ensuring efficient dust filtration.

[0010] Furthermore, the sealing plate is made of rubber and is in contact with the cone. By setting the sealing plate, the upper end of the cone is sealed.

[0011] Furthermore, one end of the spring is fixedly connected to the support ring, and the other end of the spring is fixedly connected to the baffle. The spring facilitates the repositioning of the baffle.

[0012] Furthermore, one end of the compression spring is fixedly connected to the limiting plate, and the other end of the compression spring is fixedly connected to the slip ring. By setting the compression spring, the limiting plate can be easily reset. Attached Figure Description

[0015] The implementation examples are basically as follows Figure 1As shown, this embodiment provides a solid waste separation device for lime production, including a kiln-down lime dust collector 1, a pneumatic conveying pipeline 5 for the kiln-down lime dust collector 1, a kiln-down lime dust collector conveying valve 10 in the middle of the pneumatic conveying pipeline 5, a dust collection ash hopper 3 on the pneumatic conveying pipeline 5, a transfer station lime dust collector pneumatic conveying pipeline 6 on the dust collection ash hopper 3, a transfer station lime dust collector conveying valve 9 in the middle of the pneumatic conveying pipeline 6, and a kiln-down lime dust collector pneumatic conveying valve 9 on the pneumatic conveying pipeline 5. The newly modified pneumatic conveying pipeline 7 is equipped with a screening tower lime powder bin 4. The newly modified pneumatic conveying pipeline 7 is equipped with a pipe reducer 13. The pipe reducer 13 and the pneumatic conveying pipeline 6 of the transfer station lime dust collector are connected by a newly modified pneumatic conveying pipeline 8 of the transfer station lime dust collector. A second pipe switching valve 12 is installed in the middle of the newly modified pneumatic conveying pipeline 8 of the transfer station lime dust collector. A first pipe switching valve 11 is installed in the middle of the pneumatic conveying pipeline 6 of the transfer station lime dust collector. A transfer station lime dust collector 2 is installed at the end of the pneumatic conveying pipeline 6 of the transfer station lime dust collector.

[0016] like Figure 1 , Figure 2 , Figure 3As shown, the lime dust collector 2 at the transfer station includes a base 21, which is fixedly connected to the pneumatic conveying pipeline 5 of the lime dust collector under the kiln. A shell 22 is threadedly connected to the outer side of the base 21. A cone 23 is fixedly connected to the upper end of the base 21. A support ring 24 is fixedly connected inside the cone 23. A connecting rod 25 is slidably connected inside the support ring 24. A sealing plate 26, made of rubber, is fixedly connected to the upper end of the connecting rod 25. The sealing plate 26 contacts the cone 23, sealing the upper end of the cone 23. A baffle 27 is fixedly connected to the lower end of the connecting rod 25. A spring 28 is installed on the outer side of the connecting rod 25. One end of spring 28 is fixedly connected to support ring 24, and the other end of spring 28 is fixedly connected to baffle 27. By setting spring 28, baffle 27 can be easily reset. A filter screen 29 is fixedly connected inside the housing 22. A support shaft 210 is installed inside the filter screen 29 via bearings. A square rod 211 is fixedly connected to the lower end of support shaft 210. A limit plate 212 is fixedly connected to the lower end of square rod 211. A slip ring 213 is slidably connected to the outer side of square rod 211. A compression spring 214 is provided on the outer side of square rod 211. One end of compression spring 214 is fixedly connected to limit plate 212, and the other end of compression spring 214 is fixedly connected to slip ring 213. A compression spring 214 is provided to facilitate the reset of the limiting plate 212. A scraper 215 is fixedly connected to the surface of the slip ring 213. The scraper 215 is slidably connected to the filter screen 29 and fixedly connected to the housing 22. The scraper 215 scrapes against the filter screen 29. A fan blade 216 is fixedly connected to the outer side of the support shaft 210. A support plate 217 is fixedly connected to the inside of the housing 22. A suction pump 218 is fixedly installed at the upper middle part of the support plate 217. The air outlet pipe of the suction pump 218 passes through the support plate 217 and is fixedly connected to the support plate 217. A cover 219 is fixedly connected to the lower outer side of the air outlet pipe of the suction pump 218. The cover 219 is designed to ensure that the fan blades 216 receive airflow evenly. The suction pump 218 draws air to create a negative pressure at the bottom of the housing 22, causing the sealing plate 26 and the cone 23 to separate, allowing dust to enter the housing 22. The sealing plate 26 is reset by the spring 28, sealing the upper end of the cone 23 to prevent dust backflow. The dust is filtered by the filter screen 29. The airflow drives the fan blades 216 to rotate the support shaft 210, which in turn causes the square rod 211 to rotate the scraper 215 through the slip ring 213. This causes the scraper 215 to scrape against the filter screen 29, making the filter screen 29 less prone to clogging and ensuring dust filtration efficiency.

[0017] The specific implementation process of this utility model is as follows: During use, the suction pump 218 draws air from the lower end of the support plate 217, thereby creating a negative pressure in the lower part of the housing 22. This causes the sealing plate 26 to move upward, disengaging it from the cone 23. During this process, the sealing plate 26 drives the connecting rod 25 to move upward, which in turn moves the baffle 27 to compress the spring 28. This compression of the spring 28 allows the airflow to carry dust into the housing 22, where it is filtered by the filter screen 29. The suction pump 218 draws air from the lower part of the housing 22, creating a negative pressure. A negative pressure is created, causing the sealing plate 26 and the cone 23 to separate, allowing dust to enter the housing 22. The sealing plate 26 is then reset by the spring 28, sealing the upper end of the cone 23 to prevent dust backflow. The dust is filtered through the filter screen 29, and the airflow drives the fan blade 216 to rotate the support shaft 210. This causes the square rod 211 to rotate the scraper 215 through the slip ring 213, which in turn causes the scraper 215 to scrape against the filter screen 29, making the filter screen 29 less prone to clogging and ensuring dust filtration efficiency.

[0018] The suction pump 218 creates a negative pressure at the bottom of the housing 22, causing the sealing plate 26 and the cone 23 to separate, allowing dust to enter the housing 22. The spring 28 then resets the sealing plate 26, sealing the upper end of the cone 23 and preventing dust from flowing back.

[0019] Dust is filtered by the filter screen 29, and the airflow drives the fan blade 216 to rotate the support shaft 210. This causes the square rod 211 to rotate the scraper 215 through the slip ring 213. The scraper 215 then scrapes against the filter screen 29, making the filter screen 29 less prone to clogging and ensuring dust filtration efficiency.
