Description

Technical Field

[0001] This utility model relates to the technical field of PP granule production equipment, specifically to a raw material processing device for PP granule production. Background Technology

[0002] During the production of PP granules, PP granules often contain iron impurities, such as screws and debris. If these impurities enter the plastic processing equipment, they can damage the equipment and affect the purity of the final product. Existing technologies generally use magnetic separators to remove iron from PP granules. However, existing magnetic separators, such as the flat belt magnetic separator disclosed in CN106890726B, include a feeding mechanism, a washing mechanism, a sorting mechanism, an unloading mechanism, a tensioning device, a water separation mechanism, a conveyor belt, a support-type receiving trough, and idlers. The feeding mechanism can only be fixedly installed above the magnetic separation structure. Because the feeding mechanism and the magnetic separation structure are close together, the maintenance space for both the feeding mechanism and the magnetic separation structure is small, making operation inconvenient.

[0003] While existing technologies may already offer solutions to the aforementioned problems, this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0004] To solve the problems mentioned in the background art, the present invention is achieved through the following technical solution: a raw material processing equipment for PP granule production, including a frame and a magnetic separator, wherein the magnetic separator is arranged on the frame and a feeding structure is provided on the frame;

[0005] The feeding structure includes a lead screw module, which is mounted on a frame. A right-angle frame is provided on the side wall of the moving end of the lead screw module. A material box is hinged to the upper wall of the moving end of the lead screw module. An electric push rod is hinged between the right-angle frame and the material box.

[0006] The material box includes an inlet box, the lower wall of which is inclined, and a discharge pipe is provided on the lower wall of the inlet box. The discharge pipe has multiple V-shaped bends, and a baffle is provided at one end of the discharge pipe. Multiple material passage holes are equally spaced on the baffle.

[0007] Preferably, a control box is provided on the frame.

[0008] Preferably, a receiving trough is provided at one end of the magnetic separator, and a collection trough is provided on the frame and below the magnetic separator.

[0009] Preferably, the lead screw module is arranged along the width direction of the magnetic separator.

[0010] Preferably, the width of the discharge pipe is two-thirds of the width of the magnetic separator.

[0011] Preferably, the right-angle frame and the movable end of the lead screw module are an integrated structure.

[0012] Beneficial effects

[0013] This utility model provides a raw material processing device for PP granule production. Compared with the prior art, it has the following advantages: PP granules are added into the inlet box and then enter the outlet pipe. In the outlet pipe, they pass through multiple V-shaped bending structures to change the vertical movement direction of the PP granules, which acts as a buffer and reduces the overall falling speed of the PP granules. This allows the PP granules to spread out to a certain extent in the width direction. Then, they flow out from multiple material passages on the baffle. These material passages divide the PP granules into several small and evenly spaced PP granule material flows. At the same time, the screw module reciprocates, causing the PP granules to cover the magnetic separator in a thin and evenly dispersed state, ensuring full contact between the PP granules and the magnetic separator and guaranteeing the iron removal effect. When maintenance is required, the electric push rod is extended. The extension end of the electric push rod pushes the material box to rotate upward on the moving end of the screw module, causing one end of the outlet pipe to tilt away from the magnetic separator. This facilitates maintenance of the material passages on the baffle and provides more space for maintaining the magnetic separator. Attached Figure Description

[0019] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example: Those skilled in the art shall connect all electrical components and their compatible power supplies in this case with wires, and select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence shall refer to the working principle described below, in which the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.

[0021] Please see Figure 1-4 A raw material processing device for PP granule production includes a frame 1 and a magnetic separator 2, wherein the magnetic separator 2 is mounted on the frame 1 and a feeding structure is provided on the frame 1.

[0022] It should be noted that frame 1 is used to install magnetic separator 2. Through the operation of magnetic separator 2, iron impurities mixed in with PP particles added to magnetic separator 2 can be removed, ensuring the purity of PP particles. The structure and working principle of magnetic separator 2 can refer to the suspended conveyor belt magnetic separator 2RCYQ light permanent magnet magnetic separator produced by Weifang Yunhai Machinery Equipment Co., Ltd. The structure of frame 1 is not limited, as long as it can install magnetic separator 2 and make the equipment stably set on the ground. The feeding structure is set above the non-magnetic end of magnetic separator 2. This is existing technology and will not be described in detail here. This technical solution protects the specific structure and function of the feeding structure.

[0023] Specifically, the feeding structure includes a lead screw module 3, which is mounted on the frame 1. A right-angle frame 4 is provided on the side wall of the moving end of the lead screw module 3. A material box 5 is hinged to the upper wall of the moving end of the lead screw module 3. An electric push rod 6 is hinged between the right-angle frame 4 and the material box 5.

[0024] The material box 5 includes an inlet box 51. The lower wall of the inlet box 51 is inclined. A discharge pipe 52 is provided on the lower wall of the inlet box 51. Multiple V-shaped bending structures are provided on the discharge pipe 52. A baffle 53 is provided at one end of the discharge pipe 52. Multiple material passage holes 54 are opened at equal intervals on the baffle 53.

[0025] It should be noted that during the raw material processing, the electric push rod 6 is in a retracted state, and the lower end of the discharge pipe 52 is aligned with the top of the magnetic separator 2. PP granules are added into the inlet box 51. Under the action of gravity, the PP granules enter the discharge pipe 52. The PP granules pass through multiple V-shaped bending structures in sequence. The V-shaped bending structures change the direction of movement of the PP granules in the vertical direction, which plays a buffering role and reduces the overall falling speed of the PP granules. When the PP granules fall on the wall of the V-shaped bending structure, they will be impacted and rolled, causing the PP granules to spread out to a certain extent in the width direction. Then, they pass through multiple material passages 54 on the baffle 53. The material flows out from the middle, and multiple material passages 54 divide the PP particles into several small and evenly spaced PP particle material streams. At the same time, the screw module 3 reciprocates, so that the PP particles cover the magnetic separator 2 in a thin layer and evenly dispersed state, so that the PP particles are in full contact with the magnetic separator 2 and the iron removal effect is guaranteed. When the equipment needs to be maintained, the electric push rod 6 is controlled to extend. The extension end of the electric push rod 6 pushes the material box 5 to rotate upward on the moving end of the screw module 3, so that one end of the discharge pipe 52 tilts away from the magnetic separator 2, which facilitates the maintenance of the material passages 54 on the baffle 53 and provides a larger space for the maintenance of the magnetic separator 2.

[0026] As a preferred and further option, a control box 7 is provided on the frame 1 for controlling the operation of the device;

[0027] Preferably, and further, one end of the magnetic separator 2 is provided with a receiving trough 8 for collecting PP particles after iron removal, and a collection trough 9 is provided on the frame 1 and below the magnetic separator 2 for collecting iron impurities.

[0028] Preferably, the lead screw module 3 is arranged along the width direction of the magnetic separator 2;

[0029] Preferably, the width of the discharge pipe 52 is two-thirds of the width of the magnetic separator 2, providing space for the lateral movement of the discharge pipe 52;

[0030] As a preferred and further option, the right-angle bracket 4 and the movable end of the lead screw module 3 are integrated into one structure.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
