[0002] Low VOC polyurethane foaming catalyst is a catalyst specially designed to reduce volatile organic compound (VOC) emissions and odors during the polyurethane foaming process. Traditional polyurethane rigid foam releases VOCs and unpleasant odors during production and use. These substances have a negative impact on indoor air quality and human health. In order to solve these problems, low VOC polyurethane foaming catalysts came into being, aiming to minimize the emission of these harmful substances.

A pressure detection structure that rotates with the stirring structure is arranged inside the catalyst feeding tank. The pressure generated between the stirring structure and the catalyst during the stirring process is used to realize pressure detection. The residual amount of catalyst inside the feeding tank is judged according to the position of the pressure detection response, and the residual amount of catalyst inside the feeding tank is supplemented according to the detection result. It can effectively ensure the sufficiency of the catalyst inside the feeding tank and ensure the stability of the catalyst use in the production process of polyurethane prepolymer. A feeding structure and a storage structure are arranged on one side of the feeding tank, and the catalyst inside the storage structure is detected and alarmed, so as to facilitate timely replenishment of the storage structure.

The number of partition baffles 131 can be controlled according to the amount of raw material reaction, thereby controlling the amount of raw material feeding. At the same time, the elastic force of the fitting spring 135 can be used to make the fitting rotating rod 136 drive the fitting sealing plate 137 to rotate, which can realize the rotation feeding of the partition baffle 131, and at the same time, when feeding is not needed, the partition baffle 131 can be sealed by the fitting sealing plate 137, which is convenient for sealed storage of the ground raw materials and avoids contact between the raw materials and air, thereby affecting the catalytic effect of the raw materials.

[0027] The heating box 204 and the heater 205 are used to heat the mixing box 201, so as to facilitate the production of low-VOC polyurethane foaming catalyst. The mixing tripod 209 and the mixing driven wheel 210 are driven to rotate by the mixing motor 208. The mixing driven wheel 210, the meshing gear ring 211 and the mixing driving wheel 212 are meshed and connected to each other, so that the mixing driving wheel 212 drives the first mixing spiral blade 214 to rotate, and at the same time, the mixing driven wheel 210 drives the second mixing spiral blade 215 and the stirring frame 216 to rotate. The rotation of 216 can not only realize the revolution of the second mixing spiral blade 215 and the stirring frame 216, and realize horizontal stirring of the raw materials, but also realize the up and down stirring of the raw materials through the rotation of the first mixing spiral blade 214 and the second mixing spiral blade 215, thereby improving the mixing effect of the raw materials. The first mixing spiral blade 214 drives the stirring bracket 217 and the spiral cleaning blade 218 to rotate, so that the inner wall of the mixing box 201 can be cleaned to avoid the residue of raw materials and the waste of raw materials.
