Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust collector technology, and in particular to a dust collector for a cement mill batching station with an air inlet duct designed to prevent material blockage. Background Technology
[0002] Dust collectors at cement mill batching stations are crucial environmental protection equipment in cement production. They primarily operate on a filtration principle. Dust-laden gas enters and is evenly distributed between filter bags via a flow guiding device. The filter bags are made of high-temperature and corrosion-resistant fiber materials, trapping dust particles on their outer surface. Clean gas then passes through the filter bags and is discharged. Simultaneously, pulse jet cleaning is employed. When dust accumulation increases the resistance of the filter bags, compressed air is injected into the bags through pulse valves, causing the bags to expand and vibrate to dislodge the dust. The cleaning process is automatically controlled.
[0003] Chinese patent CN217369590U discloses a dust collector for a cement mill batching station with an improved inlet duct for preventing material blockage. The dust collector includes a main body mounted on a support frame. An inlet duct connected to the cement mill batching station is located below the main body, and an outlet is located above it. A movable spray pipe assembly is located within the horizontal section of the inlet duct. The spray pipe assembly has a curved nozzle and a circumferential nozzle at one end. The other end of the spray pipe assembly extends from the bend in the inlet duct and connects to a jet nozzle. The jet nozzle is mounted on a movable platform, which is set on a support platform. The support platform is fixedly connected to one side of the support frame. This dust collector for a cement mill batching station, by improving the horizontal section of the inlet duct, effectively reduces material blockage caused by material accumulation, lowers material conveying resistance, and improves the dust collection efficiency and effectiveness.
[0004] Existing technologies often have the following drawbacks: during actual use of dust collectors in cement mill batching stations, the caking of impurities at the bend of the inlet pipe can easily cause blockages, leading to material blockage and reducing the performance of the dust collectors.

[0029] Reference Figure 1 As shown, this utility model provides a technical solution: a dust collector for a cement mill batching station with anti-clogging air inlet pipe, including a dust collector body 1, an air outlet pipe 2 connected to the surface of the dust collector body 1, an air inlet structure 3 on the surface of the dust collector body 1, and an auxiliary structure 4 on the surface of the air inlet pipe 301.
[0030] The following section will explain the specific configuration and function of its intake structure 3 and auxiliary structure 4.
[0031] Reference Figures 1-3 As shown in this embodiment, the air intake structure 3 includes an air intake pipe 301 fixedly connected to the surface of the dust collector body 1. The other end of the air intake pipe 301 is connected to a folded pipe 302, and the other end of the folded pipe 302 is connected to an installation pipe 303. By setting the air intake structure 3, flexible bending and adjustment of the air intake pipe is facilitated, which not only facilitates the crushing of impurities but also meets the usage needs of different users for the air intake pipe opening. A pivot pin 306 is fixedly connected to the side wall of the air intake pipe 301. A rotating bar 305 is rotatably connected to the side wall of the pivot pin 306. A connecting pin 304 is fixedly connected inside the rotating bar 305, and the connecting pin 304 is fixedly connected to the surface of the installation pipe 303. By setting a torsion-compatible structure between the fixed pipe and the air intake pipe 301, the direction of the pipe opening of the installation pipe 303 can also be adjusted according to usage requirements.
[0032] A positioning block 308 is fixedly connected to the side wall of the pivot pin 306. A pin 309 is slidably connected inside the positioning block 308. Several insertion holes 307 are arranged circumferentially on the surface of the pivot bar 305, the size of which matches the size of the pin 309. The pin 309 is inserted into the inner side of the insertion hole 307, enabling the locking installation between the twisted fixed tube and the air intake pipe 301. A stop block 310 is fixedly connected to the surface of the pin 309, and a spring 311 is sleeved on the surface of the pin 309. The two ends of the spring 311 are fixedly connected to the stop block 310 and the positioning block 308, respectively. The pin 309 is inserted into the inner side of the insertion hole 307 by the elastic force of the spring 311 between the positioning block 308 and the stop block 310.
[0033] Reference Figures 1-2 and Figure 4As shown, specifically, the auxiliary structure 4 includes a collection pipe 41 fixedly connected to the lower side of the intake pipe 301, with a threaded block 42 threadedly connected to the inner side of the collection pipe 41. By setting the auxiliary structure 4, and by providing a structure for collecting impurities at the position of the folded pipe 302, the phenomenon of impurities falling deep into the intake pipe 301 is avoided, further improving the usability of the intake structure 3 position. A rotating block 43 is fixedly connected to the lower end of the threaded block 42. The side wall of the rotating block 43 is provided with anti-slip texture 46, and an elastic pad 45 is glued to the surface of the rotating block 43. By setting the anti-slip texture 46 on the rotating block 43, the friction between the hand and the rotating block 43 is increased, facilitating the twisting operation of the rotating block 43. An arc-shaped groove 44 is opened on the surface of the threaded block 42. Impurities can also flow into the inner side of the arc-shaped groove 44 on the threaded block 42 along the folded pipe 302.
[0034] Working principle: When hardened impurities appear at the bend in the pipe, first pull out the pin 309. After the pin 309 is pulled out from the inside of the insertion hole 307, the rotating bar 305 on the outside of the rotating pin 306 can be rotated. At this time, the intake pipe 301 and the rotating pipe can be twisted. During the twisting process, the folding pipe 302 will bend back and forth, which can break up the hardened impurities. Then, rotate the pipe opening of the mounting pipe 303 downward to dump the broken impurities. After that, release the pin 309, and the pin 309 will be positioned by the positioning block 308. The spring 311 between the stop block 310 and the inner side of the insertion hole 307 is inserted to realize the locking installation between the fixed tube and the air inlet tube 301 after twisting. By setting the fixed tube and the air inlet tube 301 to be rotatable, the direction of the pipe opening of the installation tube 303 can also be adjusted according to the usage requirements, which meets the usage needs of different users. By setting the air inlet structure 3, it is convenient to flexibly bend and adjust the air inlet pipe, which not only facilitates the crushing of impurities, but also meets the usage needs of different users for the air inlet pipe opening.
[0035] The threaded block 42 is rotated into the inside of the collecting tube 41. The anti-slip texture 46 on the rotating block 43 increases the friction between the hand and the rotating block 43, making it easier to twist the rotating block 43. During the bending of the folded tube 302, impurities can also flow into the inside of the arc groove 44 on the threaded block 42 along the folded tube 302. Opening the threaded block 42 allows for the periodic treatment of impurities inside the threaded block 42. The elastic pad 45 improves the tightness of the threaded block 42 when it is rotated into the inside of the collecting tube 41. The auxiliary structure 4, which collects impurities at the position of the folded tube 302, prevents impurities from falling deep into the intake pipe 301, further improving the performance of the intake structure 3.
