A polyurethane insulation board production system

Abstract

The invention belongs to the technical field of high polymer material production equipment, and particularly relates to a production system of a polyurethane heat preservation board. The production system comprises a first upper bottom plate, a second upper bottom plate, a third upper bottom plate, a crushing module and a stirring module, wherein the first upper bottom plate is arranged on the second upper bottom plate through a fixing rod, the second upper bottom plate is arranged on the third upper bottom plate through a fixing rod, the crushing module is fixedly arranged between the first upper bottom plate and the second upper bottom plate, and the stirring module is fixedly arranged between the second upper bottom plate and the third upper bottom plate; and a first feeding port is formed in the first upper bottom plate, the first feeding port and a second feeding port are used for conveying solid isocyanate into a feeding device, the crushing module is used for crushing the isocyanate, and the stirring module is used for further crushing and stirring the isocyanate. The production system is mainly used for feeding the isocyanate in the processing polyurethane heat preservationmaterial, further uniform treatment can be carried out on the isocyanate, and the treating quality of the raw material can be improved.

Description

technical field [0001] The invention belongs to the technical field of polymer material production equipment, in particular to a production system of polyurethane insulation boards. Background technique [0002] When producing polyurethane, various production raw materials will be added to the reactor for reaction. Before adding, the mass will be weighed according to the ratio of various reactants, and then added. However, this method of weighing and adding has the following problems: the adding method is artificial intermittent adding, which causes the reaction rate to increase rapidly when adding, and then gradually decreases, resulting in unstable reaction rate and affecting product quality. At the same time, this addition method can only be processed in a reactor. After the processing is completed, the next batch of raw materials is added to the reactor for processing. Continuous assembly line processing cannot be achieved, and the production efficiency is relatively low...

Problems solved by technology

However, this method of weighing and adding has the following problems: the addition method is artificial intermittent addition, which causes the reaction rate to increase rapidly when adding, and then gradually decreases, resulting in unstable reaction rate and affecting product quality.

At the same time, this addition method can only be processed in a reactor. After the processing is completed, the next batch of raw materials is added to the reactor for processing. Continuous assembly line processing cannot be achieved, and the production efficiency is relatively low.

[0003] There are also technical solutions for feeding devices in the prior art. For example, a Chinese patent with application number 201621437232.4 discloses a feeding device for isocyanate synthesis, which involves the technical field of polymer material production equipment, including reactors, reactors There is a supporting platform on one side of the supporting platform, a feeding platform is provided on the supporting platform, baffles are provided on both sides of the feeding platform, an L-shaped fixing frame is arranged on the supporting platform, and a pushing mechanism is arranged on the L-shaped fixing frame. One end of the mechanism is provided with a push plate, the push plate sticks to the feeding platform, one side of the support platform is provided with a bracket, the support plate is provided with a support plate, and the support plate is provided with a feeding cylinder, which is located above the feeding platform. Although the scheme can realize the automatic feeding of isocyanate, it can also solve the threat of harmful gas to workers; however, this technical scheme cannot homogenize and break isocyanate, and cannot homogenize isocyanate in layers, so that isocyanate cannot be fully processed in the reaction. melted; made the scheme limited
