Description

Technical Field

[0001] This utility model relates to the field of chain extender processing technology, and in particular to an integrated machine for pretreatment, crushing and screening of polyurethane chain extender raw materials. Background Technology

[0002] Existing pretreatment crushing and screening devices, in order to increase the utilization rate of the raw materials to be processed, will set the screen plate at an angle so that the uncrushed raw materials are sent back to the crushing device by the conveying device for secondary crushing. However, the raw materials are prone to contact with moisture and stick to the conveying components, making secondary crushing impossible. For example, a fertilizer processing pretreatment device disclosed in Chinese Patent Application No. CN202321530627.9, uses a first conveying device and a second conveying device to send the fertilizer raw materials that have not passed through the first and second screen plates back to the first and second crushing devices for secondary crushing, ensuring the utilization rate of fertilizer raw materials. However, when transported by the conveying device, the raw materials are prone to contact with moisture inside the device and stick to the spiral conveyor blades in the conveying device, making secondary crushing impossible. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an integrated machine for pre-treatment, crushing and screening of polyurethane chain extender raw materials. The machine is equipped with a conveyor belt to transport the raw materials, and baffles to smooth the raw materials so that they fall evenly into the housing. A heating rod is installed inside the baffles to dry the raw materials, reducing internal moisture and preventing them from sticking to the components. A guide groove is provided on the lower surface of the cover to prevent water from flowing into the housing. A support rod is installed inside the housing to support the screen plate, with the top of the support rod contacting the conveyor belt. A vibrating rod inside the support rod vibrates the conveyor belt, screen plate, and inclined plate, preventing the raw materials from sticking to the screen plate and conveyor belt. The screen plate is designed with a concave shape towards the center, allowing the raw materials to slide to the center of the screen plate due to vibration. A pressure block, slidably connected to the inner wall of the housing, crushes raw materials that are too large to pass through the screen plate, increasing the utilization rate of the raw materials.
