Through the following description, relevant staff can make various changes and modifications within the scope not deviating from the technical idea of the present utility model. The technical scope of the present utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.

[0021] The present utility model is further described with reference to the following drawings:

[0022] As Figures 2 to 4 shown, a hopper of a pellet separator has a housing 100. A main magnetic separation drum 200 is provided inside the housing 100. A secondary magnetic separation drum 300, a pneumatic separator 400, and a screen 500 are provided below the main magnetic separation drum 200. The upper part of the main magnetic separation drum 200 communicates with the feed inlet 110 of the housing 100. A first guide plate 210 and a second guide plate 220 are provided below. The first guide plate 210 guides the secondary magnetic separation drum 300, and the second guide plate 220 guides the screen 500. A wind guide plate 410 is provided on one side of the pneumatic separator 400, and the wind guide plate 410 guides above the screen 500. A storage hopper 600 is provided below the screen 500. A main dust passage 420 is provided below the pneumatic separator 400. A secondary dust passage 310 is provided on the side of the secondary magnetic separation drum 300 close to the pneumatic separator below, and a steel pellet passage 320 is provided on the other side.

[0023] As Figure 2 shown, driving motors 700 are provided on both the main magnetic separation drum 200 and the secondary magnetic separation drum 300. The driving motors 700 are fixedly connected to the outside of the housing 100. The rotation directions of the main magnetic separation drum 200 and the secondary magnetic separation drum 300 are opposite, avoiding dust from being adsorbed on the pellets under the action of centrifugal force and further separating the dust on the pellets.

[0024] As Figure 4 、 5 shown, a blanking gate 230 is provided at the blanking position below the main magnetic separation drum 200. An electromagnetic valve 231 is provided on the blanking gate 230 and is opened and closed under the control of the electromagnetic valve 231.

[0025] As Figure 2 、 3 shown, a plurality of inspection doors 120 are provided on the housing 100. The upper and back sides of the housing 100 can be disassembled for maintenance. At the same time, the inspection door 100 in the present utility model is designed larger, and the internal structure is clear at a glance, making the maintenance more clear.

[0026] The housing 100 is provided with a mounting bracket 130 which is transversely arranged and has connecting seats at both ends. The mounting bracket 130 is used to mount the device on a steel platform and connect it to other equipment, making the overall structure more concise.

[0027] A third guide plate 111 is provided at the feed inlet 110. The third guide plate 111 guides the main magnetic separation drum 200 and can introduce the materials at the feed inlet 110 into the main magnetic separation drum 200.

[0028] The third guide plate 111 is installed in the housing through a guide plate adjusting seat 112, and the guide plate adjusting seat 112 can adjust the angle of the third guide plate 111.

[0029] The height of the present utility model is 2 meters, the width is 1.6 meters, and the length dimension is 2 meters. When in use, the length can be changed according to actual needs, making it more applicable.

[0030] When the present utility model is in use, the shot is conveyed by a screw conveyor or slides into the machine from the discharge hopper of a bucket elevator. After the shot slides in, it slides towards the main magnetic separation drum 200 via the third guide plate for primary magnetic separation. At this time, most of the shot and a small amount of ash slide past the second guide plate 220 and are screened by the air separator 400. The clean shot falls into the screen 500 and then slides into the storage hopper 600, waiting for subsequent processing. The dust, under the suction of the air separator 400, enters the main dust passage 420 and finally falls into the ash storage box through a hose at the lower part of the main dust passage 420. There is an anti-backflow device in the hose.

[0031] During primary magnetic separation, most of the ash and a small amount of shot slide into the second magnetic separation drum 300 through the first guide plate 210 and then undergo secondary magnetic separation. The remaining ash enters the secondary dust passage 310 and falls into the ash storage box through a hose. The shot enters the shot passage 320 after secondary magnetic separation and slides into the shot blasting chamber through a hose. Since this batch of shot has not been air-selected, there is dust on its surface and it needs to be recycled twice.

[0032] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
