One end of a spring 49 is fixedly connected to the inner wall of the rectangular groove 48. A slider 410 is fixedly connected to the end of the spring 49 away from the rectangular groove 48. A scraper 411 is installed at the bottom of the slider 410.
[0031] like Figure 2 As shown, in a preferred embodiment, based on the above method, the circumferential surface of the threaded sleeve 44 is further fixedly connected to the telescopic end of the limiting telescopic rod 412, and the fixed end of the limiting telescopic rod 412 is fixedly connected to the bottom of the cover 41. The function of the limiting telescopic rod 412 is to limit the threaded sleeve 44 and prevent the threaded sleeve 44 from moving away from its original movement path.
[0032] like Figure 3As shown, in a preferred embodiment, based on the above method, there are three connecting blocks 47, which are arranged in a circumferential array on the inner wall of the body 3. The rectangular groove 48 is located on the movement trajectory of the slider 410. The rectangular groove 48 and the slider 410 cooperate with each other. The function of the slider 410 is that when the scraper 411 comes into contact with a relatively hard sugar stain, the slider 410 compresses the spring 49 so that the spring 49 is forced to drive the scraper 411 to scrape off the sugar stain.
[0033] like Figure 4 , Figure 5 As shown, in a preferred embodiment, based on the above method, an auxiliary device 5 is further provided on the inner wall of the machine body 3. The auxiliary device 5 includes a sieve hole 51, which is located at the bottom of the machine body 3. A dust collection box 52 is provided at the bottom of the machine body 3. A filter plate 53 is fixedly connected to the inner wall of the dust collection box 52. A control panel 54 is provided on the circumferential surface of the machine body 3. A feed inlet 55 is provided on the top of the machine cover 41. The function of the sieve hole 51 is to allow the sugar stains scraped off by the scraper 411 to pass through the sieve hole 51, move away from the machine body 3, and enter the dust collection box 52.
[0034] like Figure 4 As shown, in a preferred embodiment, based on the above method, a handle 56 is fixedly connected to the side of the dust collection box 52, and a caster wheel 57 is fixedly connected to the bottom of the dust collection box 52. The caster wheel 57 is used to facilitate the staff to drag the dust collection box 52 away so as to clean the dust collection box 52.
[0035] like Figure 5 As shown, in a preferred embodiment, based on the above method, the number of sieve holes 51 is several and they are arranged in a circular array at the bottom of the machine body 3. The dust collection box 52 is set on the top of the base plate 1. The function of the dust collection box 52 is to collect sugar cubes or dust that fall from the inside of the machine body 3.
[0036] like Figure 1 , Figure 2 , Figure 4 As shown, in a preferred embodiment, based on the above method, there are several support legs 2 arranged in a circumferential array at the bottom of the body 3, several connecting plates 45 arranged in a circumferential array on the circumferential surface of the threaded sleeve 44, and a ring 46 slidably connected to the inner wall of the body 3. The function of the support legs 2 is to support the body 3 and prevent the body 3 from tipping over during use.
[0037] Specifically, in use of this self-cleaning baghouse dust collector for sugar industry boilers: the operator first closes the cover 41, then starts the external power supply, forcing the motor 42 to start. The threaded rod 43 rotates under force, causing the threaded sleeve 44 to move vertically up and down on the circumference of the threaded rod 43 via the limiting telescopic rod 412. The connecting plate 45, fixed on the circumference of the threaded sleeve 44, drives the ring 46 to move vertically up and down on the inner wall of the machine body 3. This is achieved through the connecting plate 45 fixed at the bottom of the ring 46. The connecting block 47 drives the scraper 411 to scrape away stubborn sugar stains on the inner wall of the machine body 3. When the scraper 411 comes into contact with more stubborn sugar stains, the scraper 411 is forced to stop moving, but the linear motion driven by the motor 42 does not stop, causing the spring 49 fixed on the side of the slider 410 to be compressed. When the spring 49 is compressed to a certain range, coupled with the continuous downward linear motion, the scraper 411 scrapes away the stubborn sugar stains, avoiding the disadvantages of needing manual dust removal which is time-consuming and labor-intensive, and improving work efficiency.
[0038] When sugar stains or other dust fall due to gravity, they enter the dust collection box 52 located below the machine body 3 through the sieve holes 51 at the bottom of the machine body 3. At the same time, the staff can also inject water into the interior of the machine body 3 through the feed port 55 located at the top of the machine cover 41 to clean the interior of the machine body 3. When the sugar stains have been inside the dust collection box 52 for a period of time and need to be cleaned, the staff can move the dust collection box 52 by using the handle 56 fixed to the dust collection box 52 and the universal wheels 57 fixed to the bottom, avoiding the time and effort of manual handling and making it more convenient for the staff.
[0039] All technical features in this embodiment can be freely combined according to actual needs.
[0040] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
