TECHNICAL FIELD
[0001] The present application relates to the technical field of particle processing, in particular to a particle discharge device and a granulator. BACKGROUND
[0002] A granulator is a machine specially used for cutting various small particle materials. It is commonly used in the processing and preparation of plastic particles. Its working principle is to cut the material into small particles through rotating cutters. After the material is sent into the machine from the feed port of the granulator body, it is cut and rotated by the cutters to form particles of the desired size. Then the particles are discharged from the discharge port of the granulator body and fall onto the receiving device such as a receiving tray or a conveyor belt.
[0003] However, in the process of particle falling, static electricity is generated between particles and air, and between particles and particles, which accumulates a large amount of static electricity when the particles fall onto the receiving device, which can easily cause harm to the operator and even cause fire risks.
[0004] Therefore, how to solve or improve the problem of accumulation of a large amount of static electricity when the particles fall onto the receiving device in the related art has become an important technical problem for those skilled in the art to solve. CONTENT OF THE INVENTION
[0005] Therefore, the present application provides a particle discharge device and a granulator to solve or improve the problem of accumulation of a large amount of static electricity when the particles fall onto the receiving device in the related art.
[0006] In a first aspect, the present application provides a particle discharge device, comprising:
[0007] A discharge pipeline made of conductive material is grounded, a first end of the discharge pipeline is used to communicate with the discharge port of the granulator body, and a second end of the discharge pipeline is used to be arranged at the receiving device, and the particles can be slidably conveyed along the discharge pipeline.
[0008] Optionally, the discharge pipeline is arranged in a spiral shape, and the particles can be spirally conveyed along the discharge pipeline.
[0009] Optionally, further comprising:
[0010] A wire, a first end of the wire is in electrical connection with the discharge pipeline, and a second end of the wire is grounded.
[0011] Optionally, the discharge pipeline comprises:
[0012] A connector for connecting with the discharge port;
[0013] A pipeline body, a first end of the pipeline body is communicated with the joint, and a second end of the pipeline body is configured to be arranged at the material receiving device, and the particles can be conveyed in the pipeline body.
[0014] Optionally, a cross section of the discharge pipeline is circular.
[0015] Optionally, a material of the discharge pipeline is stainless steel.
[0016] In a second aspect, the application further provides a pelletizer comprising any of the pellet discharge devices.
[0017] Optionally, the pellet discharge device further comprises a pelletizer body and a material receiving device, a first end of a discharge pipeline of the pellet discharge device is communicated with a discharge port of the pelletizer body, and the material receiving device is arranged at a second end of the discharge pipeline.
[0018] Optionally, the pelletizer further comprises:
[0019] a platform, the pelletizer body is arranged on the platform;
[0020] a supporting leg connected to a surface of the platform away from the pelletizer body.
[0021] Optionally, the pelletizer further comprises:
[0022] a roller connected to an end of the supporting leg away from the platform.
[0023] The pellet discharge device provided by the application comprises a discharge pipeline. The material of the discharge pipeline is conductive and grounded. A first end of the discharge pipeline is communicated with a discharge port of a pelletizer body, and a material receiving device is arranged at a second end of the discharge pipeline. After plastic material is put into the pelletizer body from a feeding port, the pelletizer body cuts the plastic material into plastic particles, and the plastic particles are discharged from the discharge port and then enter the discharge pipeline from the first end of the discharge pipeline for conveying. Since the particles are conveyed by sliding along the discharge pipeline in sequence, the mutual friction between the particles and the air and between the particles is reduced, thereby reducing the generation of static electricity. Since the discharge pipeline is made of metal and grounded, when the plastic particles slide in the discharge pipeline, the generated static electricity can be conducted to the discharge pipeline and then discharged to the ground. Thus, the accumulation of a large amount of static electricity on the particles conveyed to the material receiving device is avoided. BRIEF DESCRIPTION OF DRAWINGS

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative effort are within the scope of protection of the present application.
[0030] The embodiments of the present application will be described below in combination with Figures 1 to 2 .
[0031] According to the embodiments of the present application, in one aspect, a particle discharge device is provided, as shown in Figure 1 and Figure 2 , comprising: a discharge pipeline 1. The material of the discharge pipeline 1 is a metal conductive material such as iron or stainless steel, and is grounded. The first end of the discharge pipeline 1 is communicated with the discharge port of the granulator body 2, so that the particles discharged from the discharge port of the granulator body 2 can enter from the first end of the discharge pipeline 1. The material receiving device 7 is arranged at the second end of the discharge pipeline 1.
[0032] The discharge pipeline 1 can be inclined to ensure that the particles can be conveyed along the discharge pipeline 1.
[0033] In this way, after the plastic material is put into the granulator body 2 from the feeding port, the granulator body 2 cuts the plastic material into plastic particles, and the plastic particles are discharged from the discharge port and then enter the discharge pipeline 1 from the first end of the discharge pipeline 1 for conveying. The plastic particles slide along the discharge pipeline 1 to the second end and are then discharged from the second end of the discharge pipeline 1 to the material receiving device 7.
[0034] Because the particles are conveyed sequentially along the discharge pipe 1, friction between the particles and the air, and between the particles themselves, is reduced, thus minimizing static electricity generation. Furthermore, since the discharge pipe 1 is made of metal and grounded, the static electricity generated when the plastic particles slide and contact the pipe wall during its conveyance is conducted to the discharge pipe 1 and then discharged to the ground. This prevents a large amount of static electricity from accumulating on the receiving device 7.
[0035] It is worth noting that the discharge pipe 1 can also be made of insulating material, with a conductive layer on its wall. In this case, grounding the conductive layer can also discharge static electricity from the particles.
[0036] In optional embodiments, such as Figure 2 As shown, the discharge pipe 1 is configured in a spiral shape. Plastic particles are discharged from the discharge port and then enter the discharge pipe 1 from its first end for transport. The plastic particles are transported in the discharge pipe 1 along a spiral trajectory. This increases the transport time of the plastic particles in the discharge pipe 1, thereby increasing the contact time between the plastic particles and the pipe wall of the discharge pipe 1, ensuring that the particles have sufficient time to discharge static electricity to the discharge pipe 1 during transport.
[0037] In an optional embodiment, the particle discharge device further includes a wire 3. The first end of the wire 3 is energized and connected to the discharge pipe 1, while the second end of the wire 3 is grounded. In this way, when the plastic particles are conveyed in the discharge pipe 1, the static electricity generated by their contact with the pipe wall and mutual friction can be conducted to the discharge pipe 1 and then discharged to the ground through the wire 3, thereby preventing the accumulation of a large amount of static electricity after the particles are conveyed to the receiving device 7.
[0038] In an optional embodiment, the discharge pipe 1 includes a connector and a pipe body. The connector is connected to the first end of the pipe body. Thus, by connecting the connector to the discharge port of the pelletizer body 2, the first end of the pipe body is connected to the discharge port. Furthermore, the second end of the pipe body is located at the receiving device 7. Particles discharged from the discharge port of the pelletizer body 2 are transported within the pipe body and then discharged from the second end of the pipe body onto the receiving device 7.
[0039] Alternatively, the connector can be connected to the discharge port of the pelletizer body 2 first, and then the first end of the pipeline body can be inserted into the connector to complete the connection between the first end of the pipeline body and the discharge port.
[0040] In some embodiments, the discharge pipe 1 is a circular pipe with a circular cross-section. This design allows for smoother particle transport within the discharge pipe 1, preventing interference from sharp edges that could affect particle transport speed and reduce transport efficiency.
[0041] In some other embodiments, the material of the discharge pipeline 1 is stainless steel. This effectively avoids corrosion of the discharge pipeline 1, so that the service life of the discharge pipeline 1 is longer.
[0042] According to the embodiments of the present application, in another aspect, as Figure 1 shown, a pelletizer is also provided, which includes any of the pellet discharge devices described above. The technical effects brought by the pelletizer are consistent with those of the pellet discharge device, and thus will not be described again.
[0043] In optional embodiments, as Figure 1 shown, the pelletizer further includes a pelletizer body 2 and a receiving device 7. The pelletizer body 2 has an inlet and an outlet, and a cutting mechanism is arranged in the pelletizer body 2. After the plastic material enters the pelletizer body 2 from the inlet, the cutting mechanism in the pelletizer body 2 cuts the plastic material into plastic particles, which are discharged from the outlet.
[0044] The first end of the discharge pipeline 1 of the pellet discharge device is in communication with the outlet of the pelletizer body 2, and the receiving device 7 is arranged at the second end of the discharge pipeline 1. The particles discharged from the outlet enter the discharge pipeline 1 and are transported to the receiving device 7.
[0045] In further embodiments, as Figure 1 shown, the pelletizer further includes a platform 4 and a leg 5. The leg 5 is connected to the bottom surface of the platform 4 to form a frame. The end of the leg 5 away from the platform 4 is supported on a support surface, so that the frame is supported on the support surface. The pelletizer body 2 is connected to the surface of the platform 4 away from the leg 5. Thus, the frame composed of the platform 4 and the leg 5 supports the pelletizer body 2.
[0046] The first end of the discharge pipeline 1 is connected to the outlet of the pelletizer body 2, and the receiving device 7 is arranged on the support surface and located at the second end of the discharge pipeline 1. Thus, the particles discharged from the outlet enter the discharge pipeline 1 of the pellet discharge device and are transported, and can then be discharged from the second end of the discharge pipeline 1 to the receiving device 7.
[0047] In still further embodiments, as Figure 1 shown, the pelletizer further includes a roller 6. The roller 6 is connected to the end of the leg 5 away from the platform 4, and the roller 6 is placed on the support surface, so that the leg 5 and the platform 4 are supported. In this way, the frame composed of the platform 4 and the leg 5 can be moved to any position as needed, making the operation more convenient.
[0048] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the present application.
