Description

Technical Field

[0001] This utility model relates to the field of feeding technology, and in particular to a feeding device with a built-in vibrating screen. Background Technology

[0002] In order to put the powder into the batching tank, a corresponding feeding mechanism is needed, such as a screw feeder to send the powder into the feeding hopper at the top of the batching tank, so that the powder can fall into the batching tank.

[0003] The feeding mechanism typically lacks a screening function. Therefore, a vibrating screen or other screening equipment is required to screen the powder before feeding it into the feeding mechanism, which occupies a relatively large area. To reduce the footprint, the vibrating screen could be integrated into the feeding mechanism above the batching tank. However, this increases the difficulty of maintaining the vibrating screen and replacing the screen mesh, requiring improvement. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device with a built-in vibrating screen for screening and feeding powder materials, thereby improving maintenance convenience.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A feeding device with a built-in vibrating screen includes: a fixed base, a vibrating screen, a screen mesh, a floating ring, a hook plate, and a feeding hopper. The vibrating screen is mounted on the fixed base, and a pipe joint extending to the bottom of the fixed base is provided at the bottom of the vibrating screen. The feeding hopper is suspended above the vibrating screen. The floating ring is located at the top opening of the vibrating screen, and a cone extending downward into the vibrating screen is provided at the bottom of the floating ring. The screen mesh is located at the bottom of the cone. Supports are provided on both sides of the vibrating screen on the fixed base. The hook plate is vertically and flexibly mounted inside the support, and one end of the hook plate extends to the bottom edge of the floating ring.

[0007] The outer diameter of the floating ring is larger than the opening diameter of the vibrating screen.

[0008] The support frame has a fixed frame located above the floating ring at its top, and the feeding hopper is mounted on the fixed frame.

[0009] The hook plate is an L-shaped curved plate.

[0010] The bracket has a vertically arranged slide rail on its inner side, and a slider connected to the hook plate is provided on the slide rail.

[0011] The bracket has a support seat located above or below the slider on its inner side, and the support seat has a lifting drive mechanism connected to the slider or hook plate.

[0012] The lifting drive mechanism is a pneumatic cylinder, an electric telescopic rod, or a hydraulic cylinder.

[0013] The beneficial effects of this utility model are as follows: A feeding device with a built-in vibrating screen allows powder in the feeding hopper to fall into the vibrating screen, be screened by the screen mesh, and finally be fed into the mixing tank below through the pipe joint, realizing automatic screening and feeding. After feeding is completed, the floating ring is driven to rise by the hook plate, so that the screen mesh is lifted off the vibrating screen. The screen mesh and floating ring can then be disassembled using a forklift, which facilitates cleaning of the screen mesh or replacement with a new screen mesh (original mesh or screen mesh of different mesh), improving maintenance convenience. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the structure of this utility model;

[0015] Figure 2 yes Figure 1 A schematic diagram of the structure after the floating ring rises. Detailed Implementation

[0016] The following is combined Figures 1-2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0017] like Figure 1 The feeding device with a built-in vibrating screen shown includes: a fixed base 1, a vibrating screen 2, a screen mesh 13, a floating ring 3, a hook plate 9, and a feeding hopper 5. The vibrating screen 2 is mounted on the fixed base 1, and a pipe connector 12 extending from the bottom of the vibrating screen 2 to the bottom of the fixed base 1 is provided. The pipe connector 12 is connected to the mixing tank below to feed powder into the mixing tank. In addition, the fixed base 1 can be connected to the frame of the mixing tank and fixed above the mixing tank to improve space utilization.

[0018] The feeding hopper 5 is suspended above the vibrating screen 2. The powder in the feeding hopper 5 can fall into the vibrating screen 2, be screened by the screen 13, and finally be sent to the mixing tank below through the pipe joint 12.

[0019] The floating ring 3 is positioned on the top opening of the vibrating screen 2, with its outer diameter larger than the opening diameter of the vibrating screen 2, preventing it from falling into the screen. In this embodiment, a fixed frame 6 is positioned above the floating ring 3 on the top of the support 4, and the feeding hopper 5 is mounted on the fixed frame 6 and secured with screws, ensuring structural stability.

[0020] like Figure 2 As shown, the bottom of the floating ring 3 is provided with a cone 14 extending downward into the vibrating screen 2, and the screen 13 is provided at the bottom of the cone 14 and can be welded and fixed so that the floating ring 3, the cone 14 and the screen 13 can move up and down synchronously.

[0021] Supports 4 are provided on both sides of the vibrating screen 2 on the fixed base 1. The hook plate 9 is movably mounted on the inner side of the support 4, and one end of the hook plate 9 extends to the lower edge of the floating ring 3. In this embodiment, the hook plate 9 is an L-shaped curved plate, which can lift the floating ring 3 upward. When the vibrating screen 2 is working, the hook plate 9 descends and does not contact the floating ring 3, so it does not affect the operation of the vibrating screen 2.

[0022] After feeding is completed, the hook plate 9 drives the floating ring 3 to rise, causing the screen 13 to detach from the vibrating screen 2. A forklift can then be used to move and disassemble the screen 13 and the floating ring, facilitating cleaning of the screen 13 or replacement with a new screen (original mesh or a different mesh), thus improving maintenance convenience. Replacing with a screen of a different mesh also improves adaptability to different types of powders.

[0023] A slide rail 7 is vertically arranged on the inner side of the bracket 4. A slider 8 connected to the hook plate 9 is mounted on the slide rail 7 to guide the lifting and lowering of the hook plate 9, improving stability. A support base 11 is located above or below the slider 8 on the inner side of the bracket 4. A lifting drive mechanism 10 connected to the slider 8 or the hook plate 9 is mounted on the support base 11. In this embodiment, the lifting drive mechanism 10 uses a pneumatic cylinder, an electric telescopic rod, or a hydraulic cylinder, and its extension and retraction can be controlled by a PLC. Figure 2 As shown, this enables the hook plate 9 to be raised and lowered.

[0024] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
