Description

Technical Field

[0001] This utility model relates to a screening and collection device for filler masterbatch, belonging to the technical field of material screening and collection equipment. Background Technology

[0002] With the widespread use of plastics in packaging, automobiles, construction and other fields, and in order to reduce production costs, companies are increasingly using filler masterbatches to replace some of the resin, resulting in a continuous rise in the demand for filler masterbatches.

[0003] Over the years, filler masterbatch collection equipment has made significant progress in technology and the market, but it still faces challenges such as cost, maintenance and standardization.

[0004] Currently, the main methods for collecting masterbatch include: centralized dust collection systems (suitable for large-scale production, collecting masterbatch through pipelines to reduce dust pollution); mobile collection devices (suitable for small-scale or flexible production, easy to move and operate); and vacuum feeders (using negative pressure to suck up masterbatch, reducing waste and pollution). However, there is a lack of equipment suitable for collecting masterbatch of various specifications.

[0005] In the future, intelligent, environmentally friendly, and customized masterbatch collection systems will be the main development directions. To adapt to this trend, it is necessary to design a masterbatch collection system suitable for various scales, utilizing negative pressure and centralized pipeline collection. Summary of the Invention

[0006] The purpose of this invention is to solve the problems existing in the collection of traditional filler masterbatch by proposing a filler masterbatch screening and collection device.

[0007] The technical solution of this utility model is as follows: a filling masterbatch screening and collection device, including a conveyor belt and a storage tank.

[0008] The storage tank is a vertical cylindrical structure. A suction pipe perpendicular to the horizontal plane is set in the center of the storage tank. There is a conical space between the outer wall of the suction pipe and the inner wall of the storage tank. Multiple discharge ports are evenly distributed along the circumference in the lower part of the conical space. A guide plate is provided at the upper part of the suction pipe, and the lower pipe opening is directly facing the conveyor belt. An exhaust pipe is provided at the center of the top of the storage tank.

[0009] The ratio of the inner diameter of the air intake pipe and the suction pipe is 2:1.

[0010] Each of the discharge ports is equipped with a valve switch.

[0011] The exhaust duct is connected to the exhaust fan, which provides negative pressure; the exhaust duct is also connected to the dust collection system, which sends the collected dust to the dust collection system.

[0012] The guide plate is conical, with the top of the cone directly above the center of the suction pipe opening.

[0013] The beneficial effects of this utility model are that the device can effectively separate dust and masterbatch by sucking masterbatch from the conveyor belt through negative pressure, ensuring the purity of the collected masterbatch and reducing dust pollution; by controlling the size of the suction pipe and the exhaust pipe, masterbatch of various specifications can be collected, and the masterbatch falls back into the silo after entering the silo through the guide plate; the storage tank can be equipped with multiple discharge ports, which is conducive to packaging and prevents the silo from being overfilled. Attached Figure Description

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

[0015] In the diagram, 1 is the conveyor belt; 2 is the suction pipe; 3 is the storage tank; 4 is the guide plate; 5 is the air duct; 6 is the discharge port; and 7 is the valve switch. Detailed Implementation

[0016] The specific embodiments of this utility model are as follows: Figure 1 As shown.

[0017] This embodiment discloses a filling masterbatch screening and collection device, which includes a conveyor belt 1 and a storage tank 3.

[0018] In this embodiment, the storage tank 3 is a cylindrical vertical structure. A suction pipe 2 perpendicular to the horizontal plane is set in the center of the storage tank 3. There is an annular conical space between the outer wall of the suction pipe 2 and the inner wall of the storage tank 3. Multiple discharge ports 6 are evenly distributed along the circumference at the bottom of the annular conical space. A guide plate 4 is provided at the top of the suction pipe, and the lower pipe opening is directly facing the conveyor belt 1. An air duct 5 is provided at the center of the top of the storage tank 3.

[0019] In this embodiment, the guide plate 4 is fixed directly above the suction pipe 2 by two steel bars welded to the barrel wall, 3cm above the suction pipe opening; the lower end of the suction pipe opening is 2cm above the material surface of the conveyor belt.

[0020] In this embodiment, the conveyor belt 1 transports the produced masterbatch to the area below the suction pipe 2. Under negative pressure, the suction pipe draws the masterbatch into the storage tank 3. When the masterbatch reaches the guide plate 4, it is diverted from both sides. Under inertia, the masterbatch rises along both sides and falls back to the bottom of the storage tank. Dust generated during the production process enters the exhaust pipe 5 with the wind force. The exhaust pipe 5 connects the negative pressure and dust collection system. The diameter ratio of the exhaust pipe 5 to the suction pipe 2 is 2:1, ensuring that the wind force of the suction pipe 2 is greater than that of the exhaust pipe 5. The masterbatch enters the storage tank 3 without being carried into the exhaust pipe 5, thus achieving separation of the masterbatch and dust. Multiple discharge ports 6 are distributed at the bottom of the storage tank. Each discharge port 6 is equipped with a valve switch 7. The masterbatch in the storage tank 3 is collected by the valve switch 7 of the discharge port 6.
