Description

Technical Field

[0001] This utility model relates to the field of feeding conveyor technology, specifically a feeding and lifting machine for a pellet mill. Background Technology

[0002] Granulators are currently the mainstream granulation equipment used by enterprises. During granulation, powdered materials need to be lifted and fed into the granulator via an elevator. In the production process, the capacity of an existing granulator basically determines the capacity of that equipment. In order to increase the overall capacity, enterprises need to purchase multiple granulators to operate simultaneously.

[0003] In existing technologies, when multiple pellet mills are in production, powder materials need to be added separately. Then a problem arises: in the actual production process, due to various objective factors, such as different pause times, different downtime, and different original production capacities, the amount of material required by each pellet mill per unit time is different.

[0004] Adding material to the feed hoppers of multiple pellet mills at different times and frequencies creates significant inconvenience. Often, when preparing to add material to the feed hopper of one pellet mill, there is still a considerable amount remaining, while at the same time, the feed hoppers of one or more other pellet mills are empty and urgently need replenishment. This results in the pellet mills running idle, limiting production potential and requiring improvement. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a pellet mill feeding and lifting machine, which solves the problem of limited production potential caused by the difficulty in timely adding materials to multiple pellet mills when enterprises are simultaneously pelletizing.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A pellet mill feeding elevator includes multiple inclined screw conveyors, the lower end of which is connected to a feed hopper, and the upper end of which is connected to a cloth cylinder via a discharge pipe. The lower end of the cloth cylinder is connected to the feed inlet of the pellet mill. The tops of the multiple feed hoppers are connected to a feeding trough, and two spiral conveying rods are installed side by side in the feeding trough. A gearbox is fixed to one end of the feeding trough, and a transmission gear installed on the two spiral conveying rods and meshing with each other is provided in the gearbox. A drive motor is installed on one side of the gearbox, and the output shaft of the drive motor is inserted through the gearbox and connected to one of the spiral conveyor rods.

[0007] Preferably, the feeding trough is a long trough, and multiple screw conveyors are equidistantly arranged along the axial direction of the feeding trough.

[0008] Preferably, the two ends of the cloth tube are respectively installed on the discharge pipe and the inlet via hose clamps.

[0009] Preferably, the two end walls of the feeding trough are both arc-shaped curved surface structures, and the bottom of the feeding trough is a curved surface structure that bulges downward from the middle compared to the sides.

[0010] Preferably, the two spiral conveying rods have the same shape and size, and the spiral directions of the two spiral conveying rods are consistent.

[0011] Preferably, the two spiral conveying rods are positioned inside the lower part of the feeding trough.

[0012] Preferably, the drive motor is a servo motor.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention connects a feeding trough to the feed hoppers of multiple pellet mills and installs two bolted conveying rods inside the feeding trough. When adding powdered material, it can be added at any position in the feeding trough. Regardless of the rate at which the pellet mill consumes material, there is no need to add material separately. The screw conveying rods will automatically push the material along the feeding trough, and the material will automatically fall into the feed hopper below and be transported to the pellet mill by the screw conveyor. This ensures that each pellet mill can be quickly replenished with material, bringing convenience to production and solving the problem of limited production potential caused by the difficulty in timely adding material to multiple pellet mills when they are granulating at the same time.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1-3 As shown, this utility model provides a technical solution: a pellet mill feeding elevator, including multiple inclined screw conveyors 1, the lower end of the screw conveyor 1 is connected to a feed hopper 2, the upper end of the screw conveyor 1 is connected to a discharge pipe 3 and a cloth cylinder 4, the lower end of the cloth cylinder 4 is connected to the feed inlet 6 of the pellet mill 5, the two ends of the cloth cylinder 4 are respectively installed on the discharge pipe 3 and the feed inlet 6 through hose clamps. When the equipment is running, it will vibrate. The vibration amplitude and frequency of the two equipment are different. The problem is well solved by conveying materials through the flexible cloth cylinder 4. Multiple feed hoppers 2 are connected to a feeding trough 7 at their top. The feeding trough 7 is a long trough. Multiple screw conveyors 1 are equidistantly arranged along the axial direction of the feeding trough 7, so that the feeding efficiency of multiple screw conveyors 1 is relatively uniform. Two screw conveying rods 8 are installed side by side in the feeding trough 7. The two screw conveying rods 8 are located inside the lower part of the feeding trough 7. Both ends of the feeding trough 7 have arc-shaped curved surface structures, and the bottom of the feeding trough 7 has a curved surface structure that bulges downward from the middle and the sides. This makes it convenient for excess material that has been conveyed to the end by one screw conveyor 8 in the feeding trough 7 to be conveyed in the opposite direction by another screw conveyor 8. At the same time, it makes it convenient for material to enter the lower feeding trough 7 when it is being conveyed horizontally in the feeding trough 7. A gearbox 9 is fixed at one end of the feeding trough 7. The gearbox 9 contains a transmission gear 10 that is installed on two spiral conveying rods 8 and meshes with each other. The two spiral conveying rods 8 have the same shape and size, and the spiral direction of the two spiral conveying rods 8 is the same. A drive motor 11 is installed on one side of the gearbox 9. The drive motor 11 is a servo motor. The output shaft of the drive motor 11 is inserted through the gearbox 9 and connected to one of the spiral conveying rods 8. Depending on the actual needs, the drive motor 11 can work continuously or intermittently.

[0018] Working principle: Powder material is directly added into the feeding trough 7. The drive motor 11 and transmission gear 10 drive two spiral conveyor rods 8 to rotate in opposite directions. The two spiral conveyor rods 8 push the material near them in opposite directions along the feeding trough 7. During the pushing process, the material automatically falls into the lower feed hopper 2 and is transported to the pellet mill 5 by the spiral conveyor 1 for pelleting. The pellet mill 5 with high capacity consumes material quickly, so the material in the corresponding feed hopper 2 is consumed quickly, and more material falls down from the upper feeding trough 7. The pellet mill 5 with low capacity consumes material slowly, so the material in the corresponding feed hopper 2 is consumed slowly, and less material is replenished from the upper feeding trough 7. When excess powder material is pushed to the end of the feeding trough 7 by the spiral conveyor rods 8, because the inner wall of the end of the feeding trough 7 is a curved structure, the powder material can be pushed in the opposite direction by another spiral conveyor rod 8, so that the material is repeatedly pushed along the feeding trough 7, thereby ensuring that each pellet mill 5 can obtain sufficient material.
