Description

Technical Field

[0001] The invention relates to the technical field of feed production, and in particular to a dust removal device for poultry feed production and a dust removal method thereof. Background Art

[0002] Poultry feed is a general term for food for poultry in commercial circulation. The breeding objects include chickens, ducks, geese and other domestic poultry. It is a necessary material condition for maintaining the health of poultry and producing poultry products, and is crucial to the growth and development of poultry.

[0003] Feed includes more than ten kinds of feed raw materials, such as soybean, soybean meal, corn, fish meal, amino acid, miscellaneous meal, whey powder, oil, meat and bone meal, grain, feed additives, etc. During the production and processing of feed, the surface of feed usually carries a lot of dust, and its own temperature is also high, so it needs to be dusted and cooled before packaging and transportation; At present, dust removal equipment is usually equipped in the production process of feed to adsorb the dust on the surface of the feed. However, since most poultry feed is granular, the feed will accumulate during the transportation and dust removal process, and most dust removal equipment usually only performs a single dust removal and cooling treatment on the feed. This results in the feed being squeezed and accumulated during the processing, and the dust removal and cooling of the feed are not thorough enough, thereby affecting the processing effect and feed quality of the feed. Therefore, a dust removal device for poultry feed production and a dust removal method thereof are proposed to solve the above problems. Summary of the invention

8. A dust removal device for poultry feed production according to claim 7, characterized in that: The dust collecting member (6) further comprises a retaining ring (67) fixedly connected to the support tube (66); a threaded ring (68) threadedly connected to the support tube (66); and a filter bag (69) mounted on a side of the threaded ring (68) away from the retaining ring (67). An external thread is formed on the outer side of the support tube (66), and the external thread cooperates with the thread on the inner wall of the threaded ring (68).

9. A dust removal method for a dust removal device for poultry feed production, characterized in that: The following steps are involved: S1, conveying: the feed to be dusted is conveyed into the conveying bin (2) through the feed hopper (5), and the conveying paddle (48) is driven to rotate by the started driving motor (412), so that the rotation speed of the conveying paddle (48) reaches 30-60 r / min, so that the feed in the conveying bin (2) is stably conveyed into the inner cylinder (41); S2, vibration dust removal: the dual-axis motor (441) is started and the speed is controlled to be 900-1500 r / min, so as to control the rotation of the rotating shaft (442) and the rotating disk (443), and then the rotating disk (443) drives the connecting rod (444) to rotate at the eccentric position of the rotating disk (443), thereby driving the inner cylinder (41) to vibrate vertically and reciprocatingly in the outer cylinder (1), and vibrating and guiding the feed introduced onto the guide plate (42). During the guiding process, the dust removal fan (414) is started and the speed is controlled to be 1300-1800 r / min to blow air, so as to blow away the dust raised during the vibration conveying process of the feed, and cool the feed; S3, pretreatment: the air blown by the dust removal fan (414) can also be guided by the ventilation tube (43), the air guide cover (45) and the ventilation pipe (47) to be transported to the conveying paddle (48) and blown out, so as to pre-cool the feed during the transportation process; S4, cyclic processing: after the feed guided by the guide plate (42) passes through the conical end of the inner tube (41) and is guided into the return pipe (49), the valve (411) on the return pipe (49) is opened, and the valve (411) on the discharge port (410) is closed, so that the once processed feed can be transported back to the transport bin (2), and the dust removal and cooling operation in step S2 is repeated. The feed can be subjected to one or more cooling and dust removal treatments to improve the processing effect of the feed; S5, dust collection and filtration: When the feed is cooled during transportation, the exhaust fan (65) can be started, and the rotation speed of the exhaust fan (65) can be controlled to be 1200-1600 r / min. Then, negative pressure adsorption is generated on the outer cylinder (1), the conveying bin (2) and the inner cylinder (41) through the main pipe (62), the auxiliary pipe (63) and the suction pipe (64), and the raised dust is sucked and adsorbed through the dust suction hole (415), and then filtered and blocked by the filter bag (69) at the air outlet end of the exhaust fan (65), so as to reduce the dust adhering to the surface of the feed after the feed is cooled and discharged.
