This utility model relates to the field of mixing device technology, specifically a temperature-controlled stirring and mixing device for polycarbonate, including a stirring tank and a tank cover. An outer shell is fixedly connected to the outer wall of the stirring tank, and a heating wire is disposed between the stirring tank and the outer shell. A temperature sensor is fixedly connected to the bottom of the tank cover, and an operation panel and controller are fixedly connected to the surface of the outer shell. This utility model, by setting a filter box on the discharge pipe and inserting a filter screen inside the filter box, can filter out incompletely dissolved impurities, agglomerated particles, and debris generated by equipment wear during discharge, preventing these impurities from affecting the quality of subsequent products and reducing problems such as surface defects and uneven internal structure. Compared to the conventional method of setting a separate filtration process, it reduces equipment costs and process complexity. Furthermore, opening the sealing cover on the slag discharge pipe at the bottom of the filter box facilitates the cleaning of impurities inside the filter box.

This invention discloses a high-efficiency heat exchange reaction device for furfural production, relating to the field of furfural production technology. It includes a base plate with a support frame snapped onto its top. A heat exchange reaction and conveying separation mechanism is installed at the top of the support frame, comprising a horizontal hydrolysis reaction cylinder. The horizontal hydrolysis reaction cylinder is mounted on the top of the support frame, and a hollow rotating rod is connected inside the horizontal hydrolysis reaction cylinder. This invention has a scientifically sound and reasonable structure, is safe and convenient to use, and features a heat exchange reaction and conveying separation mechanism. Through the coordinated operation of the horizontal hydrolysis reaction cylinder and the vertical stripping reaction cylinder, a continuous process chain of "horizontal main reaction and vertical deep stripping" is formed. The spiral pusher blades achieve forced and stable conveying of solid materials, facilitating precise control of the reaction residence time. Furthermore, the vertical spiral feeder auger, in conjunction with counter-current steam, maximizes the stripping recovery of residual furfural.

This utility model relates to the field of thermal oil heater technology, and in particular to a biomass thermal oil heater. By connecting the first connection port at the end of the oil outlet pipe to the oil inlet of the heat-using equipment, and connecting the second connection port at the end of the return oil pipe to the oil outlet of the heat-using equipment, an oil circuit is formed between the thermal oil coil and the heat-using equipment. When the thermal oil inside the thermal oil coil reaches the operating temperature, the first and third valves are opened, and the thermal oil pump is started to draw the thermal oil inside the thermal oil coil into the heat-using equipment through the oil outlet pipe. At the same time, the thermal oil drawn into the heat-using equipment can flow into the return oil pipe through the oil outlet of the heat-using equipment, and then flow back into the thermal oil coil for continuous heating. This forms a closed-loop circulation system between the thermal oil coil and the heat-using equipment, thereby ensuring a continuous supply of heat to the heat-using equipment and realizing continuous heat transfer.
