Description

Technical Field

[0001] This utility model relates to the field of material feeding device technology, and in particular to a chemical raw material feeding device with screening function. Background Technology

[0002] Feeding devices, also known as elevators, are conveyor belt lifting mechanisms used for feeding materials. They are widely used in chemical production and food processing, especially in chemical production, where chemical raw materials usually need to meet particle size requirements before being put into the production line for processing. Large particles that do not meet the particle size requirements need to be crushed by a crusher before being put into the production line.

[0003] Existing feeding devices typically only have the function of conveying materials. In order to ensure that the particle size of the material entering the feeding device meets the production requirements, a crushing device is set at the front end of the feeding device. After being crushed by the crushing device, the material enters the feeding device for processing. However, since the crushing device cannot guarantee that the particle size of all crushed materials meets the requirements, some large particles are fed into the production line, thus affecting the production efficiency.

[0004] Therefore, it is necessary to propose a chemical raw material feeding device with screening function to achieve the identification and screening of large particles and improve production and processing efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing feeding devices may feed large particles of material into the production line, thereby affecting production efficiency. A chemical raw material feeding device with screening function is provided.

[0006] The technical solution of this utility model is:

[0007] A chemical raw material feeding device with screening function includes a conveyor frame, a conveyor belt, a first transmission mechanism, and a power unit installed on the conveyor frame. A collection hopper is provided on the top of the conveyor frame, and a filter drum is provided inside the collection hopper. Filter holes are opened on the side wall of the filter drum, and a guide roller is provided inside the filter drum. One end of the filter drum is provided with an outlet communicating with a crushing device, and the filter drum is provided with an inlet. The other end of the filter drum is provided with a first driven pulley, which is fixedly connected to one end of the guide roller. The output end of the power unit is connected to a first driving pulley, and the first driving pulley and the first driven pulley are driven by a transmission belt.

[0008] Furthermore, the filter drum is fixedly connected to the hopper, the hopper is fixedly connected to the conveyor frame, and the two ends of the guide roller are rotatably connected to the filter drum.

[0009] Furthermore, the first transmission mechanism includes a second driving pulley, a second driven pulley, a driving roller, and a driven roller. The second driving pulley is fixedly connected to the output end of the power device, and the second driven pulley is fixedly connected to the driving roller. The driving roller and the driven roller are respectively installed at both ends of the conveyor frame, and the power device drives the conveyor belt to move through the first transmission mechanism.

[0010] Furthermore, the feed inlet is located at the top of the filter cylinder.

[0011] Furthermore, the filter holes are located at the bottom of the side wall of the filter roller, and the filter holes are circular.

[0012] Furthermore, the power unit is fixedly connected to the conveyor frame.

[0013] This utility model discloses a chemical raw material feeding device with screening function. Since the feed inlet of the filter drum is connected to the crushing device, the chemical raw materials, after being crushed by the crushing device, can enter the filter drum through the feed inlet. The power device drives the guide roller to rotate, thereby causing the chemical raw materials to move axially within the filter drum. Small particles that meet the crushing requirements will fall out from the filter holes and onto the conveyor belt through the collection hopper. Large particles that do not meet the crushing requirements will be carried by the guide roller to the discharge port of the filter drum and returned to the crushing device for crushing again. This achieves screening of chemical raw materials of different particle sizes. Compared with traditional technology, this technical solution realizes the identification and screening of large particles, allowing large particles to re-enter the crushing device for crushing instead of entering the production line, thus improving production and processing efficiency.

[0019] Example 1

[0020] like Figure 1 and Figure 2 As shown, this embodiment provides a chemical raw material feeding device with screening function, including a conveyor frame 1, a conveyor belt 2, a first transmission mechanism and a power unit 3 installed on the conveyor frame 1, a collection hopper 4 at the top of the conveyor frame 1, a filter roller 5 inside the collection hopper 4, filter holes 6 on the side wall of the filter roller 5, a guide roller 7 inside the filter roller 5, a discharge port 8 communicating with a crushing device at one end of the filter roller 5, a feed port 9 on the filter roller 5, and a first driven pulley 10 at the other end of the filter roller 5. The first driven pulley 10 is fixedly connected to one end of the guide roller 7 by a key. The output end of the power unit 3 is connected to a first driving pulley 11 by a key. The first driving pulley 11 and the first driven pulley 10 are driven by a transmission belt.

[0021] Preferably, the filter roller 5 is fixedly connected to the collection hopper 4 with screws, the collection hopper 4 is fixedly connected to the conveyor frame 1 with screws, and the two ends of the guide roller 7 are rotatably connected to the filter roller 5 through bearings.

[0022] Preferably, the first transmission mechanism includes a second driving pulley 12, a second driven pulley 13, a driving roller 14, and a driven roller 15. The second driving pulley 12 is fixedly connected to the output end of the power unit 3 by a key, and the second driven pulley 13 is fixedly connected to the driving roller 14 by a key. The driving roller 14 and the driven roller 15 are respectively installed at both ends of the conveyor frame 1. The power unit 3 drives the conveyor belt 2 to move through the first transmission mechanism. Multiple parallel transmission rollers can also be installed between the driving roller 14 and the driven roller 15 to achieve smooth movement of the conveyor belt 2. Since the conveyor belt 2 is a relatively mature technology, it will not be described in detail here.

[0023] Preferred, such as Figure 3 As shown, the feed inlet 9 is located at the top of the filter drum 5, which facilitates the feeding of chemical raw materials.

[0024] Preferably, the filter hole 6 is located at the bottom of the side wall of the filter drum 5. The filter hole 6 is circular, and the chemical raw materials that meet the particle size requirements can fall out of the filter hole 6 under the action of gravity and enter the collection funnel.

[0025] Preferably, the power unit 3 is fixedly connected to the conveyor frame 1 with screws.

[0026] In use, the feed inlet 9 of the filter drum 5 is connected to the crushing device. After the chemical raw materials are crushed by the crushing device, they can enter the filter drum 5 through the feed inlet 9. The power unit 3 drives the guide roller 7 to rotate, thereby driving the chemical raw materials to move axially within the filter drum 5. Small particles that meet the crushing requirements will fall out from the filter holes 6 and onto the conveyor belt 2 through the collection hopper 4. Large particles that do not meet the crushing requirements will be carried by the guide roller 7 to the discharge port 8 of the filter drum 5 and returned to the crushing device for crushing again. This achieves screening of chemical raw materials of different particle sizes. Compared with traditional technology, this technical solution realizes the identification and screening of large particles, allowing large particles to re-enter the crushing device for crushing instead of entering the production line, thus improving production and processing efficiency.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model.
