The extraction equipment for chitin using shrimp shells as raw material according to claim 1 , wherein a second motor ( 558 ) is fixedly installed on the top side of the drying box ( 53 ). The power drive end of the second motor (558) is connected to the screw (553), and a second feeding hopper (68) is fixedly installed on the top of the crushing box (62). The second feeding hopper (68) An intercepting plate (69) is fixedly installed on the outer side of the crushing box (62), a second outlet (610) is fixedly installed at the bottom of the crushing box (62), and one end of the outer side of the second outlet (610) extends to the shrimp shell collection box (8) INTERNAL. 5. a method for extracting chitin with shrimp shell as raw material, is characterized in that, comprises the steps: Put clean water in the water storage tank (48), then start the auger (3), pour the prepared shrimp shells into the feeding pocket of the auger (3), and finally feed the auger (413) from the first feeding hopper (413). At this time, the water pump (41) and the first motor (43) are started. Under the action of the water pump (41), the water in the water storage tank (48) passes through the water inlet pipe (410). and the first water outlet pipe (49), and finally enter the interior of the cleaning bucket (42), and the power drive end of the first motor (43) drives the stirring roller (44) to rotate, thereby driving the stirring blade (45) to rotate synchronously. The internal shrimp shell is moved to make the cleaning more uniform, and when the soft hairs (47) on both sides of the stirring blade (45) are in contact with the shrimp shell, the cleanliness of cleaning is improved and the hygiene and safety of the shrimp shell is guaranteed; After the cleaning is completed, open the first valve (412) to discharge the dirty water from the inside of the second water outlet pipe (411), and then open the buckle (416), so that the internal shrimp shells fall to the upper end of the conveyor belt (51). , for the shrimp shells that are not completely discharged, just start the first motor (43) again, and under the action of the stirring blade (45), move the shrimp shells down, and then start the conveyor belt (51) and the heating plate (54) and the second motor (558), the clean shrimp shells enter the drying box (53) under the action of the conveyor belt (51), the baffle plate (52) prevents the shrimp shells from falling, and under the action of the heating plate (54) , the internal temperature rises, and the moisture on the surface of the shrimp shell is evaporated. At this time, the height between the telescopic rod (556) and the shrimp shell is adjusted until the brush (557) is in contact with the shrimp shell, and then the second motor Under the action of (558), the lead screw (553) is driven to rotate, and at the same time, the sliding seat (555) is simultaneously driven to reciprocate inside the chute (554), and finally the smoothing brush (557) is driven in the drying box (53) The interior of the machine is reciprocating to flatten the shrimp shell, thereby improving the drying speed of the shrimp shell; When the dried shrimp shells reach the end of the drying box (53), they will fall into the second feed hopper (68) from the first discharge port (57), and the third motor (65) is activated at this time. , so that the power drive end of the third motor (65) drives the driving wheel (66) to rotate, and under the action of the belt (67), it drives the driven wheel (64) to rotate synchronously, thereby driving the crushing roller shaft (63) to rotate. The shrimp shells are pulverized, and the pulverized shrimp shells are directly dropped into the shrimp shell collection box (8) from the second discharge port (610); After the pulverization is completed, the second valve (11) is opened, and the extraction solution in the extraction solution storage bucket (7) falls from the liquid outlet pipe (10) into the shrimp shell collection box (8). , close the second valve (11), soak the shrimp shells for 24 hours, and finally use centrifugal equipment to spin off the water and dry the internal materials to obtain the dried chitin product.
