Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of calcium carbonate powder processing, in particular to a calcium carbonate dust purification and collection device. Background Art
[0002] As an important inorganic compound, calcium carbonate is widely used in building materials and industrial fields. However, a large amount of dust is inevitably generated during its preparation and processing. This dust not only pollutes the working environment, but also affects the atmospheric environment. At the same time, it may cause health hazards after being inhaled by the human body.
[0003] During the processing of calcium carbonate, especially during the grinding process into powder, the problem of dust floating is particularly prominent. Since calcium carbonate has the characteristic of absorbing dust, these dusts not only pollute the working environment, but also may have a negative impact on the natural environment. In the prior art, although some dust collection devices reduce dust pollution by spraying atomized water, calcium carbonate will swell when it comes into contact with water, which will affect the subsequent processing steps and reduce processing efficiency.
[0004] In addition, during the crushing and screening process of calcium carbonate, there is also the problem of dust pollution. The existing calcium carbonate crusher will produce a large amount of calcium carbonate powder when crushing raw materials and screening, and the recovery effect is poor, resulting in dust dispersion, which not only pollutes the environment but also wastes materials.
[0005] In the production process of light calcium carbonate, carbonization is a commonly used process. Although this method is mature, it also produces a large amount of floating calcium carbonate dust during the production process. This dust not only affects the air quality, but also may pose a threat to the health of workers. Utility Model Content
[0006] The utility model aims to provide a calcium carbonate dust purification and collection device to solve the problem that the crushing and screening process of calcium carbonate proposed in the above background technology is accompanied by a large amount of dust generation, and the existing crusher has poor recovery effect during crushing and screening, resulting in dust dispersion, which is both polluting and wasteful.
[0007] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a calcium carbonate dust purification and collection device, including a pipeline, a driving motor is arranged inside the pipeline near one end, a filter is arranged inside the pipeline near the other end, a scraper is rotatably connected to one side of the filter, an output end of the driving motor is fixedly connected to an exhaust fan, one side of the exhaust fan is fixedly connected to a transmission shaft 1, one end of the transmission shaft 1 is connected to a transmission shaft 2 through a reducer, one end of the transmission shaft 2 passes through the filter and is fixedly connected to the scraper, one end of the pipeline is fixedly connected to an outlet pipe, a plurality of atomizing nozzles are arranged inside the outlet pipe, and the lower end of the outlet pipe is fixedly connected to a concentration box.
[0008] The utility model is further configured that a concentration tank is movably connected inside the concentration box, an opening is opened on the top of the concentration box, and an exhaust grille is fixedly connected inside the opening.
[0009] The utility model is further configured that a connecting pipe is connected between the atomizing nozzles.
[0010] The utility model is further configured that a powder collecting chamber is provided below the pipeline near the filter, and a powder collecting groove is movably connected inside the powder collecting chamber.

[0012] The utility model is further configured such that the driving motor, the reducer and the filter are fixed at different positions inside the pipeline by a fixing bracket 1, a fixing bracket 2 and a fixing bracket 3 respectively.
[0013] Beneficial effects of the calcium carbonate dust purification and collection device of the utility model:
[0014] The driving motor rotates the exhaust fan to inhale air containing calcium carbonate powder. The air continues to move forward after intercepting the powder through the filter. The exhaust fan drives the reducer through the transmission shaft, reduces the speed and drives the scraper to rotate to scrape off the powder on the surface of the filter. The filtered air enters the outlet pipe with a faster flow rate. The water mist sprayed by the atomizing nozzle combines with the remaining powder to facilitate sedimentation into the concentration box. Through the preliminary filtration of the filter and the secondary treatment of atomization sedimentation, the device can achieve efficient purification and collection of calcium carbonate dust, greatly improving the quality of the working environment.

[0023] See also Figure 1 , 2 and Figure 3 , 4A calcium carbonate dust purification and collection device comprises a pipeline 1, a driving motor 3 is arranged near one end of the pipeline 1, a filter 10 is arranged near the other end of the pipeline 1, a scraper 11 is rotatably connected to one side of the filter 10, an exhaust fan 4 is fixedly connected to the output end of the driving motor 3, a transmission shaft 15 is fixedly connected to one side of the exhaust fan 4, one end of the transmission shaft 15 is connected to the transmission shaft 2 8 through the reducer 7, one end of the transmission shaft 2 8 passes through the filter 10 and is fixedly connected to the scraper 11, an air outlet pipe 15 is fixedly connected to one end of the pipeline 1, a plurality of atomizing nozzles 16 are arranged inside the air outlet pipe 15, and a concentration box 18 is fixedly connected to the lower end of the air outlet pipe 15.
[0024] By adopting the above technical solution, the driving motor 3 drives the exhaust fan to rotate, generating suction, and sucking in air containing calcium carbonate powder through the air inlet pipe 14. After the air enters the pipeline 1, the filter 10 intercepts the powder, and the clean air continues to move forward. At the same time, the exhaust fan 4 drives the reducer 7 through the transmission shaft 1 5, and transmits the speed to the transmission shaft 2 8 after reducing the speed, driving the scraper 11 to rotate, scraping off the powder on the surface of the filter 10, and the filtered air enters the outlet pipe 15, the diameter of which is reduced and the flow rate is accelerated. The atomizing nozzle 16 in the pipe sprays water mist, which combines with the remaining powder to increase its size and weight, so as to facilitate its sedimentation to the concentration tank 20 in the concentration box 18.
[0025] A concentrating tank 20 is movably connected inside the concentrating box 18, an opening is provided at the top of the concentrating box 18, an exhaust grille 19 is fixedly connected inside the opening, a connecting pipe 17 is connected between the atomizing nozzles 16, a powder collecting chamber 12 is provided below the pipeline 1 near the filter 10, a powder collecting tank 13 is movably connected inside the powder collecting chamber 12, an air intake pipe 14 is fixedly connected to the other end of the pipeline 1, the driving motor 3, the reducer 7 and the filter 10 are respectively fixed at different positions inside the pipeline 1 by a fixed bracket 1 2, a fixed bracket 2 6 and a fixed bracket 3 9.
[0026] By adopting the above technical solution, the calcium carbonate powder scraped off by the scraper 11 will fall into the powder collecting groove 13 in the powder collecting chamber 12. When the calcium carbonate powder in the powder collecting groove 13 accumulates to a certain amount, the powder collecting groove 13 can be pulled to take it out of the powder collecting chamber 12. When the calcium carbonate powder in the concentration groove 20 is concentrated to a certain amount, the concentration groove 20 of the concentration box 18 can be pulled out for unified treatment, and the treated air is finally discharged through the exhaust grille 19. The atomizing nozzle 16 is connected to the water supply pipe through the connecting pipe 17.
[0027] The working principle of the utility model is that the crushing and screening process of calcium carbonate is accompanied by the generation of a large amount of dust. The existing crusher has a poor recovery effect during crushing and screening, resulting in dust dispersion, which is both polluting and wasteful.
[0028] When in use, the driving motor 3 drives the exhaust fan 4 to rotate, and the rotation of the exhaust fan 4 generates suction, and then the air containing calcium carbonate powder is drawn into the pipeline 1 through the air inlet pipe 14, and the filter 10 in the pipeline 1 will filter the calcium carbonate powder in the air, and the filtered calcium carbonate powder will stay on the surface of the filter 10. When the driving motor 3 drives the exhaust fan 4 to rotate, the exhaust fan 4 will drive the reducer 7 to operate through the transmission shaft 15, and the reducer 7 will reduce the speed transmitted by the transmission shaft 15, and then transmit it to the transmission shaft 2 8 to drive the scraper 11. The transmission shaft 2 8 drives the scraper 11 to rotate to scrape off the calcium carbonate powder accumulated on the surface of the filter 10, and the calcium carbonate powder scraped off by the scraper 11 will fall into the powder collecting groove 13 in the powder collecting chamber 12. When the calcium carbonate powder in the powder collecting groove 13 accumulates to a certain amount, the powder collecting groove 13 can be pulled to take it out of the powder collecting chamber 12;
[0029] The air filtered by the filter 10 will come to the outlet pipe 15. The diameter of the outlet pipe 15 is smaller than the diameter of the pipeline 1. It is mainly used to concentrate the air and speed up the flow rate of the air. A plurality of atomizing nozzles 16 are arranged in the outlet pipe 15. The atomizing nozzles 16 are connected to the water supply pipe through the connecting pipe 17. The atomizing nozzles 16 will turn the water into water mist and then spray it out. The atomized fine water droplets combine with the remaining calcium carbonate powder particles in the air to increase their size and weight, thereby making it easier to settle in the concentration tank 20 of the concentration box 18 below the outlet pipe 15. This atomization and sedimentation method effectively improves the powder collection efficiency and reduces the content of residual powder in the air. When the calcium carbonate powder in the concentration tank 20 is concentrated to a certain amount, the concentration tank 20 of the concentration box 18 can be pulled out for unified treatment, and the treated air is finally discharged through the exhaust grille 19.
