Abstract
Description
Technical Field
[0001] This utility model relates to the field of compound fertilizer production waste recycling, and in particular to a compound fertilizer production waste recycling device. Background Technology
[0002] After the compound fertilizer is granulated, the product needs to be screened to separate qualified fertilizer particles from smaller defective particles, and the defective tailings can be recycled. In order to make the screening efficient, I designed a compound fertilizer production tailings recycling device. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a compound fertilizer production tailings recycling device, including an equipment silo and a screening drum. The main body of the equipment silo is a rectangular trough structure, and a fully penetrating opening is provided at the top of the equipment silo. The screening drum is rotatably placed horizontally inside the equipment silo and includes a discharge section and a screening section. The arc-shaped side of the screening drum in the discharge section is covered with a screen, and the arc-shaped cylindrical surface array of the discharge section is provided with a discharge port. A qualified material outlet is provided in the equipment silo directly below the discharge port, and a recycling outlet is provided in the equipment silo corresponding to the bottom of the screening section. A feed inlet is provided in the middle of the circular side of the screening drum away from the discharge port. The screening drum is driven to rotate by a motor on one side, thereby driving the material to be screened and moved from the feed inlet side to the discharge port side.
[0004] The screening section of the screening drum is provided with guide bars arranged in a spiral pattern on its sidewalls.
[0005] The screening drum has a rotating shaft on the side away from the feed inlet. The rotating shaft is connected to a motor, which is mounted on the equipment compartment.
[0006] The feed inlet is provided with an annular support block on its outer ring, and a support block is provided in the middle of the rotating shaft connected to the motor; the outer arc surface of the two support blocks is provided with an annular limiting support groove; support rollers for support are provided on both sides below the limiting support groove, the support rollers are mounted on the roller frame, and one side of the roller frame is fixed to the equipment compartment.
[0007] The inner ring of the feed inlet is equipped with a bearing, the outer ring of the bearing is interference-fitted with the feed inlet, and the inner ring of the bearing is fixedly connected to a feed pipe, one side of which is fixed to the equipment compartment.
[0008] The beneficial effects of this utility model are as follows: This device uses rollers for support, which reduces the rolling friction of the screening drum. The material enters from the feed inlet, and defective products fall off the screen. The material moves along the guide bar to the discharge outlet and is sent out, making screening efficient and accurate. Attached Figure Description
[0009] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0010] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a cross-sectional view of the present invention; Figure 3 This is a magnified schematic diagram of the feed inlet. Detailed Implementation
[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments: See Figure 1-3 .
[0012] This utility model discloses a compound fertilizer production tailings recycling device, including an equipment silo 1 and a screening drum 2. The main body of the equipment silo is a rectangular trough structure, and a fully penetrating opening is provided at the top of the equipment silo. The screening drum is rotatably placed horizontally inside the equipment silo. The screening drum includes a discharge section 201 and a screening section 202. The arc-shaped side of the screening drum in the discharge section is covered with a screen, and the arc-shaped cylindrical surface of the discharge section is provided with a discharge port 3. A qualified material outlet 4 is provided in the equipment silo directly below the discharge port, and a recycling outlet 5 is provided in the equipment silo corresponding to the screening section. A feed inlet 6 is provided in the middle of the circular side of the screening drum away from the discharge port. The screening drum is driven to rotate by a motor 7 on one side, thereby driving the material to be screened and moved from the feed inlet side to the discharge port side.
[0013] The screening section of the screening drum is provided with guide strips 8 arranged in a spiral pattern on its sidewall.
[0014] The screening drum has a rotating shaft 9 on the side away from the feed inlet. The rotating shaft is connected to a motor 7, which is installed on the equipment compartment.
[0015] The feed inlet is provided with an annular support block 10 on its outer ring, and a support block 10 is provided in the middle of the rotating shaft connected to the motor; the outer arc surfaces of the two support blocks are provided with annular limiting support grooves 11; support rollers 12 for support are provided on both sides below the limiting support grooves, the support rollers are mounted on roller frame 13, and one side of the roller frame is fixed to the equipment compartment.
[0016] The inner ring of the feed inlet is provided with a bearing 14, the outer ring of the bearing is interference-fitted with the feed inlet, and the inner ring of the bearing is fixedly connected to a feed pipe 15, one side of which is fixed to the equipment compartment.
[0017] Specific operations The material is conveyed from the feed pipe 15 into the screening drum 2. The motor 7 drives the screening drum 2 to rotate through the rotating shaft 9. The material moves towards the discharge port 3 while continuously turning along the guide bar 8. Defective products leak out from the screen and are sent out from the recycling outlet 5, while qualified materials are sent out from the discharge port 3 and then from the qualified material outlet 4.
[0018] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
