Description

Technical Field

[0001] This utility model relates to the field of plastic processing, and in particular to a simple blowing system. Background Technology

[0002] Plastic granules are the basic raw material for the production of plastic products. They are granular substances used to manufacture various plastic products. Plastic granulation is a process that processes plastic waste or raw materials into granules, making them easier to store, transport, and mold. This process is crucial for the recycling of plastics and the production of plastic products.

[0003] Existing plastic pellet processing systems typically utilize fans mounted on storage equipment to pump pre-processed plastic pellets falling from the hopper through transport pipes to the storage equipment for the next packaging process. (See [link to relevant documentation]). Figure 1 Plastic granules formed after plastic processing are discharged from the discharge port of the discharge box 1', enter through the pipe 2' and are temporarily stored in the hopper 3', then enter the first transport pipe 4', and are transported to the second transport pipe 6' by the wind force of the blower 5' and transported to a high position along the second transport pipe 6', and then enter and be stored in the finished product tank 8' through the third transport pipe 7'.

[0004] However, the existing plastic pellet transportation system has the following problems: (1) When plastic pellets are transported to higher places, they are prone to getting stuck at the bottom of the second transportation pipe 6' due to excessive mass and inability to overcome gravity, causing pipe blockage and affecting feeding efficiency. (2) Processed plastic pellets are usually mixed with metal impurities such as iron filings and iron wires, which contaminate the plastic pellets and affect their quality. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a simple blowing system with a fast feeding speed, avoiding the accumulation and contamination of plastic particles, and enabling plastic particles to be transported to the finished product can faster, cleaner and easier.

[0006] A simple material blowing system includes a discharge box with a discharge port, a metal separator located at the discharge port, a funnel-shaped hopper located below the metal separator, a finished product tank and a blower connected to the hopper via transport pipes; the transport pipes include a first transport pipe located below the hopper and a second transport pipe located at a guide height; the first end of the first transport pipe is connected to the blower, and the end is connected to the second transport pipe via a connecting device; the hopper is fixedly connected to the side wall of the first transport pipe, and the inner cavity of the hopper is connected to the cavity of the first transport pipe; the connecting device includes a connecting pipe and a detachable partition, the connecting pipe having a first connecting port connected to the end of the first transport pipe, a second connecting port connected to the first end of the second transport pipe, and a third connecting port, the partition being used to close the third connecting port.

[0007] This invention addresses two main issues. First, by installing a metal separator at the discharge port of the feeding hopper, it removes metal impurities such as iron filings and wires from the plastic granules. Second, by using a connecting pipe with three connection ports that connects to both the first and second transport pipes, and sealing the third connection port with a partition, the invention solves the problem of clogging at the bottom of the second transport pipe during transport from the first to the higher-level second transport pipe.

[0008] Furthermore, the connecting pipe is a T-shaped pipe.

[0009] Furthermore, the connecting device also includes a collection tray disposed below the partition.

[0010] Furthermore, the connecting device also includes a housing, the connecting pipe is fixedly connected to the inside of the housing, the housing is provided with a second through hole adapted to the partition, and the partition can be pulled out from the second through hole.

[0011] Furthermore, a third through hole adapted to the collection tray is provided on the side wall at the bottom of the box, through which the collection tray can be pulled out. The collection tray can be used to collect plastic particles accumulated in the first and second transport pipes, and the plastic particles accumulated inside the box can be cleaned by pulling the collection tray out of the third through hole.

[0012] Furthermore, the metal separator contains several separable adsorption layers, each comprising a plurality of magnetic adsorption rods, with adjacent layers of magnetic adsorption rods spaced apart and staggered. The multiple layers of staggered magnetic adsorption rods ensure more thorough contact with the plastic particles, making it easier to adsorb metal substances such as iron wires and iron filings mixed within the plastic particles.

[0013] Furthermore, the metal separator includes a separation section and a guide section connected to the separation section; the separation section is fixedly connected to the discharge box; the bottom of the guide section is provided with a discharge port; the discharge port communicates with the discharge port; the separation section is provided with a plurality of first through holes adapted to the adsorption layer, and the adsorption layer can be extracted from the first through holes. The ability to extract the adsorption layer from the first through holes facilitates periodic cleaning of the iron wires and iron filings adsorbed by the magnetic adsorption rods of the adsorption layer.

[0014] Furthermore, the guide section has a funnel-shaped structure. This funnel-shaped structure facilitates the entry of plastic particles into the hopper's inner cavity while preventing plastic particles from accumulating at the bottom of the metal separator.

[0015] Furthermore, a connection port is formed at the junction of the hopper and the first conveying pipe; the hopper also includes an inclined baffle, the bottom of which is connected to the end of the first conveying pipe away from the fan at the connection port, and covers the connection port. To enhance the conveying efficiency of plastic granules or solve the problem of blockage in the conveying pipe cavity, it is usually necessary to increase the fan power and the airflow in the first conveying pipe. However, increasing the airflow can easily cause the plastic granules at the connection port between the hopper and the first conveying pipe to be blown out by the fan and unable to enter the first conveying pipe. This invention solves the problem of plastic granules being easily blown out by the fan by covering the connection port with a baffle.

[0033] Please see Figures 2-4 A simple blowing system includes a discharge box 1, a metal separator 2, a hopper 3, a finished product tank 5 connected to the hopper via conveying pipes, and a blower 6. The conveying pipes include a first conveying pipe 42, a second conveying pipe 44 at a higher guide point, and a third conveying pipe 46, which are connected sequentially. The first end of the first conveying pipe 42 is connected to the blower 6, and the third conveying pipe 46 communicates with the inner cavity of the finished product tank 5. The blower 6 provides the conveying power. The discharge box 1 has a discharge port.

[0034] Please see Figures 5-6The metal separator 2 is located at the discharge port. The metal separator 2 is a hollow, integrated structure, including a separation section 22 with three adsorption layers and a guide section 24 that guides plastic particles to the next device. The guide section 24 is connected below the separation section 22. The separation section 22 has a box-shaped structure, and its top is fixedly connected to the bottom of the discharge box 1 via a fixing flange. Three first through holes are provided on one inner wall of the separation section 22 from top to bottom. The shape and size of the first through holes are adapted to the adsorption layers 26, and the adsorption layers 26 can be individually extracted and separated from the first through holes. The adsorption layer 26 includes a limiting plate 262, a plurality of magnetic adsorption rods 264 fixed inside the limiting plate 262, and a first handle 266 fixed outside the limiting plate 262. The magnetic adsorption rods 264 are disposed inside the separation part 22, and the first handle 266 is disposed outside the separation part 22. The limiting plate 262 is larger than the first through hole, preventing the entire adsorption layer 26 from falling into the separation part 22 through the first through hole. The operator can pull the magnetic adsorption rods 264 of the adsorption layer 26 out of the separation part 22 by grasping the first handle 266. Furthermore, the magnetic adsorption rods 264 of adjacent adsorption layers 26 are staggered and spaced apart from each other. The guide part 24 has a funnel-shaped structure, and the bottom is provided with a discharge port communicating with the discharge port of the discharge box 1.

[0035] In this embodiment, the guide portion 24 has a square funnel-shaped structure; the three first through holes of the separation portion 22 are spaced at the same interval; the number of magnetic adsorption rods 264 in the three adsorption layers 26 of the separation portion 22 from top to bottom are 3, 4 and 5 respectively, the magnetic adsorption rods 264 in the same adsorption layer 26 are spaced at the same interval, and the magnetic adsorption rods 264 in adjacent adsorption layers 26 are staggered.

[0037] Please see Figure 4 and Figure 9 The end of the first transport pipe 42 is connected to the beginning of the second transport pipe 44 via a connecting device 7. The connecting device 7 includes a housing 72, a connecting pipe 74 fixedly connected inside the housing 72, a separable partition 76, and a collection tray 78 disposed below the partition 76. The connecting pipe 74 has a first connection port 742, a second connection port 744, and a third connection port 746, and the partition 76 is used to close the third connection port 746. The housing 72 has a second through hole adapted to the partition 76, and the partition 76 can be pulled out from the second through hole.

[0038] In this embodiment, the connecting pipe 74 is a T-shaped pipe. The first connecting port 742 passes through the side wall of the box 72 and is connected to the end of the first transport pipe 42 via a flange. The second connecting port 744 passes through the top of the box 72 and is connected to the beginning of the second transport pipe 44 via a flange. The third connecting port 746 is vertically downward and located inside the box 72. The side wall of the box 72 at the horizontal position corresponding to the third connecting port 746 is provided with a second through hole adapted to the partition 76. The partition 76 passes through the second through hole and is fixed at the third connecting port 746, thus sealing the third connecting port 746. The partition 76 is provided with a limiting part 762 protruding from the plate surface. The limiting part 762 is located outside the box 72 and is larger than the second through hole, so that the entire partition 76 cannot fall into the box 72 through the second through hole. In addition, the limiting part 762 is also provided with a second handle 764 for pulling the partition 76. The operator can pull the partition 76 out of the box 72 by holding the second handle 764. The collection tray 78 is a disc-shaped structure with raised edges and a recessed center; a third through hole adapted to the collection tray is provided on the side wall at the bottom of the box 72, and the collection tray 78 can be pulled out from the third through hole.

[0039] In other embodiments, the third connection port 746 may be horizontally disposed inside the housing 72; the top of the housing 72 corresponding to the vertical position where the third connection port 746 is located is provided with a second through hole adapted to the partition 76; the partition 76 passes through the second through hole and is fixed to the third connection port 746 and closes the third connection port 746.

[0041] The plastic granules screened by the vibrating screen in the early stage are discharged from the discharge port of the discharge box 1. When they pass through the adsorption layer 26 of the metal separator 2, the iron filings in the plastic granules are adsorbed by the magnetic adsorption rod 264. The plastic granules are discharged from the discharge port of the metal separator 2, enter and are temporarily stored in the hopper 3, and then enter the first transport pipe 42. Under the action of the wind force of the blower 3, they are transported to the second transport pipe 44 through the connecting device 7 and transported to a high position along the second transport pipe 44. Then they enter and are stored in the finished product tank 5 through the third transport pipe 46. The adsorption layer 26 is periodically extracted from the first through hole for cleaning. When plastic particles cannot overcome gravity and are transported to a higher position along the second transport pipe 44, they accumulate in the connecting pipe 74. The partition 76 is pulled out from the second through hole, allowing the plastic particles accumulated in the connecting pipe 74 to fall from the third connection port 746 onto the collection tray 78. The partition 76 is then inserted from the second through hole to reseal the third connection port 746. When the space between the partition 76 and the collection tray 78 inside the box 72 is full or the inside of the box 72 needs to be cleaned, the connecting device 7 can be removed for cleaning.

[0042] The embodiments described above are merely examples of several implementations of the utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
