Efficient sponge foaming machine capable of recycling waste heat

Abstract

The invention provides an efficient sponge foaming machine capable of recycling waste heat. The efficient sponge foaming machine comprises a tank body, wherein an annular scraping plate is movably mounted in the tank body; the periphery of the annular scraping plate is in airtight sliding contact fit with the inner periphery of the tank body; the top of the tank body is connected with the top sideof the annular scraping plate through an electric telescopic rod; through grooves are formed in the top side and the bottom side of the tank body respectively; the inner ends of fine holes are fixedly connected with the air outlet end of a one-way valve respectively; the bottom side of a first rotating plate on the lower side is rotationally connected with the upper end of an air inlet pipe through a sealing bearing; the air inlet pipe is fixedly connected with the tank body; and the lower end of a vertical pipe penetrates through the corresponding first rotating plate and communicates with the air inlet pipe. The efficient sponge foaming machine is simple in structure and ingenious in conception; a stirring tank is divided into two stirring cavities by a lifting partition plate, so thatnew material flow can be added during stirring, and the stirred material flow is continuously discharged out of the stirring tank; the two stirring cavities share one set of stirring driving device, so that the purpose of saving space is achieved, market requirements can be met, and the efficient sponge foaming machine is suitable for popularization.

Description

technical field [0001] The invention belongs to the field of sponge foaming devices, in particular to a high-efficiency sponge foaming machine for waste heat recovery and utilization. Background technique [0002] In polyurethane foam technology, when the sponge is foamed, it is usually necessary to use a stirring device to fully stir the slurry. For continuous foaming production, two stirring devices are required to stir alternately, one stirring device to stir, and the other stirring device to discharge the stirred material. It is used to solve the problem of time-consuming stirring of a single stirring device and the inability to continue to discharge the stirred material during refueling, so that the stirring device can continue to feed materials. Therefore, it is necessary to make the capacity of the stirring device larger to avoid subsequent material stirring when the stirring device is refueling Uneven, therefore, the material stirred by the large-volume stirring devi...

Problems solved by technology

[0002] In polyurethane foam technology, when the sponge is foamed, it is usually necessary to use a stirring device to fully stir the slurry. For continuous foaming production, two stirring devices are required to stir alternately, one stirring device to stir, and the other stirring device to discharge the stirred material. It is used to solve the problem of time-consuming stirring of a single stirring device and the inability to continue to discharge the stirred material during refueling, so that the stirring device can continue to feed materials. Therefore, it is necessary to make the capacity of the stirring device larger to avoid subsequent material stirring when the stirring device is refueling Uneven, therefore, the material stirred by the large-volume stirring device needs to be continuously stirred to avoid re-stratification of the stirred material, and the track of the stirring rod of the existing stirring device is fixed, resulting in low stirring efficiency. At the same time, the inner wall of the stirring tank needs Frequent cleaning will affect the mixing efficiency and cannot meet the actual needs, so we invented a high-efficiency sponge foaming machine for waste heat recovery and utilization
