Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane material production, in particular to a filtering device for polyurethane material production. Background Art

[0002] In the production process of polyurethane materials, the use of filtration devices is to remove impurities, improve product purity, and protect equipment from clogging and damage, thereby ensuring that product quality, appearance and performance meet requirements. Filters also help control reaction conditions and improve production efficiency, bringing stability and reliability to the production process. Their use can reduce the impact of impurities and solid particles, improve product consistency and reliability, while extending the service life of equipment, and ultimately improve production efficiency and product quality.

[0003] In the current production of polyurethane materials, the filter device usually uses a flat filter screen for filtering. However, if there is too much liquid to be filtered, the impurities will increase accordingly, which may cause the filter screen to be blocked. In this case, the filter screen needs to be cleaned or replaced before it can continue to work. When blocked, the filter screen is blocked by the liquid. The raw materials are mostly chemical agents. Even if you operate with rubber gloves, there is still a certain degree of danger, making it difficult to remove and increasing the difficulty of maintenance. Utility Model Content

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0025] Combined with Figure 1 , Attachment Figure 3 A filtering device for producing polyurethane materials includes a filter cartridge 1 and a filter screen 2. The lower end of the filter cartridge 1 is bowl-shaped, and a discharge pipe 12 is provided at the center of the lower end of the filter cartridge 1. A handle 13 is connected to the side wall of the filter cartridge 1 to facilitate the smooth flow of materials out of the filter cartridge 1 and avoid waste. The handle 13 is convenient for moving the filter cartridge 1.

[0026] Combined with Figure 1 , Attachment Figure 3 The filter screen 2 is arranged in the filter cylinder 1. The filter screen 2 consists of a bottom surface and a side surface. The bottom surface and the side surface of the filter screen 2 are provided with filter holes. The side wall of the filter screen 2 is inclined, which is conducive to the smooth falling of the material. At the same time, the filtering area can be increased, which is conducive to achieving sufficient filtration and improving the filtering efficiency.

[0027] Combined with Figure 3 A guide seat 3 is integrally formed on the inner wall of the filter cartridge 1, and the filter screen 2 is clamped at the lower end of the guide seat 3. The guide seat 3 is an annular seat surrounded by an inclined arc plate, which facilitates the material to flow smoothly and stably onto the filter screen 2.

[0028] Combined with Figure 2 , Attachment Figure 3 , Attachment Figure 4 The guide seat 3 is provided with a plurality of through holes, and a rotatable blocking block 4 is embedded in the through hole. The blocking block 4 is driven by an electric push rod 6 hinged on the inner wall of the filter cartridge 1. The electric push rod 6 and the inner wall of the filter cartridge 1, the blocking block 4 and the guide seat 3, and the blocking block 4 and the electric push rod 6 are connected by hinge seat 1 7, hinge seat 2 8 and hinge seat 3 9, respectively. The hinge seat 3 9 is slidably arranged below the blocking block 4. The blocking block 4 is provided with a slide groove 10 matching the hinge seat 3 9. The electric push rod 6 drives the blocking block 4 to rotate, which can ensure the effective blocking of the through hole during the filtering process and ensure a good filtering effect. At the same time, it is convenient to control the opening of the blocking block 4 without direct contact with the blocking block 4, which is safe and convenient. The electric push rod 6 is provided with a waterproof structure on the outside to prevent the electric push rod 6 from being damaged or malfunctioning.

[0029] Combined with Figure 1 , Attachment Figure 3 , a plurality of lifting rods 5 are connected to the bottom surface of the filter screen 2. A hanging ring 11 is connected to the upper end of the lifting rod 5, so that the filter screen 2 can be taken out by pulling up the lifting rod 5.

[0030] The specific implementation mode of the utility model is as follows: the filter cartridge 1 is fixed in a suitable position, and the device is connected to an external power supply, and the electric push rod 6 is controlled to extend so that the blocking block 4 completely blocks the through hole, and the polyurethane material to be filtered is placed from the top of the filter cartridge 1. The polyurethane material passes through the filter screen 2 smoothly under the action of the guide seat 3, and directly flows out from the discharge pipe 12 after being filtered by the filter screen 2. The bottom and side surfaces of the filter screen 2 can filter the polyurethane material at the same time, and impurities remain on the filter screen 2. When the bottom surface of the filter screen 2 is blocked, its side surface can still continue to filter. If the filter screen 2 is completely blocked, the electric push rod 6 is controlled to contract and drive the blocking block 4 to rotate. The unfiltered material above the filter screen 2 flows down through the through hole and then flows out through the discharge pipe 12. A collecting device is used to collect it below the discharge pipe 12. After the unfiltered material has completely flowed out, a hook is used to hook the hanging ring 11, and the filter screen 2 is lifted upward by the lifting rod 5. The filter screen 2 can be taken out for cleaning or replacement, and the clean filter screen 2 is put back into the filter cartridge 1. The electric push rod 6 is controlled to push the blocking block 4 back into the through hole to continue filtering the material.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
