Description

Technical Field

[0001] This application relates to the field of polyurethane production equipment technology, and in particular to a polyurethane feeding device with impurity removal effect. Background Technology

[0002] Polyurethane is a high-performance polymer material with good elasticity, wear resistance, corrosion resistance and heat insulation. By adjusting the raw material ratio and process, it can be used to prepare a variety of products from soft foam to rigid products, and is widely used in furniture, automobiles, construction, electronics and other fields.

[0003] Traditional feeding devices only serve as conveying channels and cannot remove residual agglomerated impurities, metal fragments, and magnetic impurities from raw materials. This necessitates the addition of filtration equipment in subsequent processes, increasing production costs and process complexity. To address these issues, we propose a polyurethane feeding device with impurity removal capabilities. Utility Model Content

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3In this utility model, a polyurethane feeding device with impurity removal effect includes a feeding cylinder 1. A base 4 is fixedly connected to the bottom end of the feeding cylinder 1. The bottom surface of the base 4 is provided with anti-slip protrusions. The base 4 can support the feeding cylinder 1 and further improve its stability. A grid plate 7 is fixedly connected to the inner wall of the feeding cylinder 1. When polyurethane enters the feeding cylinder 1, the grid plate 7 will filter the polyurethane and remove the lumpy impurities in the polyurethane. A sealing plate 5 is provided on the other side of the feeding cylinder 1. A set of pull rods 6 is fixedly connected to one side of the sealing plate 5. The other end of the set of pull rods 6 is fixedly connected to a push plate 15. The sealing plate 5 can block the flow of impurities. When the sealing plate 5 is pulled, the pull rods 6 will drive the push plate 15 to move, and the push plate 15 will push the lumpy impurities on the grid plate 7 to be discharged.

[0019] A set of symmetrical guide plates 8 are fixedly connected to the inner wall of the feeding cylinder 1. Magnetic suction plates 9 are installed on the sides of the guide plates 8 that are close to each other. A V-shaped plate 14 is set between the magnetic suction plates 9. The front and rear ends of the V-shaped plate 14 are connected to the inner wall of the feeding cylinder 1. The filtered raw material will fall onto the guide plates 8 and flow along the guide plates 8 to the V-shaped plate 14. It will fall downwards along the guide of the V-shaped plate 14 and pass through the magnetic suction plates 9. The magnetic suction plates 9 will remove the metal impurities in the polyurethane. An opening and closing door 2 is installed on the front of the feeding cylinder 1. The opening and closing door 2 is located in front of the set of guide plates 8. The opening and closing door 2 can be used to allow the magnetic suction plates 9 to be exposed, thereby facilitating the removal of metal impurities on the magnetic suction plates 9.

[0020] A discharge port 12 is provided on one side of the feeding cylinder 1. A filter screen 13 is fixedly connected to the inner wall of the feeding cylinder 1. One end of the filter screen 13 passes through the discharge port 12 and extends to the outside of the feeding cylinder 1. Polyurethane will fall onto the filter screen 13, and the filter screen 13 will remove impurities from the polyurethane again, which can remove micro-impurities in the polyurethane.

[0021] A collection box 11 is provided at the bottom of the feeding cylinder 1. The front end of the collection box 11 extends to the front of the feeding cylinder 1. The collection box 11 collects the filtered impurities for convenient centralized processing by the staff. A flow guide hood 10 is provided above the feeding cylinder 1. The flow guide hood 10 is located above the collection box 11. The flow guide hood 10 can guide the falling impurities to further ensure the effect of impurity collection.

[0022] The working principle of this application is as follows: When feeding, polyurethane is injected into the feeding cylinder 1. The polyurethane first passes through the grid plate 7, which filters out agglomerated impurities in the raw material. The filtered raw material falls onto the guide plate 8 and flows along the guide plate 8 to the V-shaped plate 14. It then falls downwards along the guide plate 14 and passes through the magnetic suction plate 9. The magnetic suction plate 9 removes metallic impurities from the polyurethane. The removed polyurethane falls onto the filter screen 13, which removes impurities from the polyurethane again. This removes microscopic impurities from the polyurethane, eliminating the need for subsequent filtration and reducing production costs.

[0023] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
