During operation, motor 16 work drives impeller 2 and rotates and produce the appeal to in the sediment dirt in the carbonization chamber 5 gets into control chamber 6 down through arranging material round hole 10 following the air current with higher speed, large granule cinder gets into in the mixed collection chamber 7 under the direction of guide plate 13, thereby has improved whole sediment efficiency of arranging.
As an embodiment of the present invention, one side of the baffle 13 close to the non-return baffle 22 is provided with an arc transition 23; the check baffle 22 is installed on the top wall of the sewage channel 12 through a torsion spring, the check baffle 22 is arranged into an arc shape, one side of the arc shape is protruded towards the lower control chamber 6, and the lower end of the check baffle 22 is abutted against the arc transition 23 of the guide plate 13. When the slag dust collecting device works, when the slag dust passes through the guide plate 13, the slag dust gradually falls to the arc transition 23, at the moment, under the action of suction force, the twisted check baffle 22 swings, so that the lower end of the check baffle 22 is separated from the arc transition 23, therefore, the slag can easily enter the mixing and collecting chamber 7, when the air flow flows backwards in the mixing and collecting chamber 7, the suction force generated by the rotation of the impeller 2 can be weakened, the check baffle 22 can reversely swing under the action of the torsion spring, and then the check baffle returns to the state of being collided with the arc transition 23, thereby making the slag and dust in the mixing and collecting chamber 7 difficult to flow back to the lower control chamber 6, further improving the efficiency of collecting the slag and dust, and the non return baffle 22 that the arc set up with bellied one side control room 6 down, can be so that be stained with the sediment dirt that attaches on non return baffle 22 when the swing by vibrations along the pitch arc landing, improve non return baffle 22's clean and tidy nature.
In one embodiment of the present invention, the thickness of the check baffle 22 is gradually decreased from top to bottom. During operation, the thickness from the top down through with non return baffle 22 progressively diminishes the setting for under the effect of suction non return baffle 22 is faster opens, and the non return baffle 22 that the lower extreme is thinner also can produce weak deformation when conflicting arc transition 23 simultaneously, thereby improves the contact compactness between the two, and the effect that the backward flow was blockked in further reinforcing.
As an embodiment of the present invention, an exhaust port 17 is opened on the outer side of the top surface wall of the mixing and collecting chamber 7, which is located on the top of the rotating shaft 15, and a filter screen plate 18 matched with the exhaust port 17 is welded at the bottom of the mixing and collecting chamber 7; two scraping plates 19 are symmetrically welded on the outer side of the rotating shaft 15 close to the top, and the scraping plates 19 are matched with the filter screen plate 18 for use. During operation, large granule cinder gets into under the direction of guide plate 13 and mixes in collecting chamber 7, and the air current that contains the dust is discharged through gas vent 17 under the filtration of filter screen 18, and the rotatory filter screen 18 that scrapers 19 on the impeller 2 simultaneously scrapes, avoids appearing blockking up, from this mix and store a large amount of cinder in collecting chamber 7, the integrated processing of being convenient for.
As an embodiment of the present invention, the bidirectional telescopic rod 9 is composed of a positioning sleeve 20 and two sliding columns 21, one end of each sliding column 21 is sleeved on each end of the positioning sleeve 20, and the sliding columns 21 are slidably connected with the positioning sleeve 20.
During the operation, in the coking production of the formed coke, a large amount of crushed and powdered coke is easily generated in the carbonization chamber in the process of transferring the formed coke raw material into and transferring the finished formed coke out, and the in-and-out of a container transfer trolley is influenced, so that the carbonization chamber needs to be cleaned regularly, the current cleaning usually adopts manual cleaning and collection, the labor amount, and operators can easily suck the lung to harm the health of the operators, therefore, the invention controls the opening and closing actions of the two supporting plates 8 by the oil cylinder 3 through the bidirectional telescopic rod 9 by arranging the horizontal bearing plate 4 with the bearing function at the bottom in the upper carbonization chamber 5, arranging a plurality of discharge round holes 10 on the horizontal bearing plate 4, hinging the bottom of the horizontal bearing plate 4 with the two supporting plates 8 with a split door structure, opening and closing the two supporting plates 8 by opening the bidirectional telescopic rod 9, conveniently discharging sundries in the carbonization chamber and sliding into the mixing and collecting chamber 7 through the inclined guide plate 13, thereby conveniently and intensively collecting the residues, the support function is realized after the closing; during the slag dust removal, if the mixed collection chamber 7 is filled with air flow backwards, the backflow phenomenon can be caused, so that the normal discharge of the slag dust is influenced, therefore, the backflow of the air flow which is filled in the mixed collection chamber 7 is blocked by the arrangement of the non-return baffle 22 which is twisted in the sewage discharge channel 12, the incomplete cleaning caused by the backflow of the slag dust is avoided, and the cleaning effect is greatly improved; when the motor 16 works to drive the impeller 2 to rotate to generate attraction, the slag dust in the upper carbonization chamber 5 is accelerated to enter the lower control chamber 6 along with the air flow through the discharge round hole 10, and large-particle slag blocks enter the mixing and collecting chamber 7 under the guidance of the guide plate 13, so that the integral slag discharge efficiency is improved; when the slag dust passes through the guide plate 13, the slag dust gradually falls to the arc transition 23, at the moment, under the action of suction force, the twisted non-return baffle 22 swings, so that the lower end of the non-return baffle 22 is separated from the arc transition 23, therefore, the slag can easily enter the mixing and collecting chamber 7, when the air flow flows backwards in the mixing and collecting chamber 7, the suction force generated by the rotation of the impeller 2 can be weakened, the check baffle 22 can reversely swing under the action of the torsion spring, and then the check baffle returns to the state of being collided with the arc transition 23, thereby making the slag and dust in the mixing and collecting chamber 7 difficult to flow back to the lower control chamber 6, further improving the efficiency of collecting the slag and dust, the raised side of the non-return baffle 22 faces the lower control chamber 6, so that slag dust attached to the non-return baffle 22 can be vibrated to slide off along an arc line when swinging, and the tidiness of the non-return baffle 22 is improved; meanwhile, large-particle slag blocks enter the mixing and collecting chamber 7 under the guidance of the guide plate 13, air flow containing dust is filtered by the filter screen plate 18 and discharged through the exhaust port 17, and meanwhile, the scraper blade 19 on the impeller 2 rotationally scrapes the filter screen plate 18 to avoid blockage, so that a large number of slag blocks are stored in the mixing and collecting chamber 7, and integrated treatment is facilitated
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
