This invention provides an extruder for wires with smooth and uniform heating, comprising a body, a die head, a neck, a barrel, a heater, a conduit, and a pump. The body encloses the barrel, which contains a screw. The body includes a heating zone and an extrusion zone. The heater is connected to the heating zone via a conduit. The die head is connected to the extrusion zone via the neck. The heating zone has a feed inlet, and the die head has a discharge outlet. Silicone oil is introduced into the heater, and the heated silicone oil is pumped into the heating zone. Existing silicone oil in the heater is pumped back to the heater, thus achieving constant temperature heating. The temperature fluctuation within the barrel is within 1°C, resulting in more uniform material heating, more stable plasticization, and a more stable material flow. This reduces common problems such as old rubber and bulging, leading to higher precision products with better electrical performance and appearance, offering significant advantages in the production of high-frequency data cables.

This utility model relates to the field of dibutyl phthalate (DBP) production technology, specifically to a device for recovering alcohol from DBP. The device includes an alcohol storage tank connected to a distillation kettle via an alcohol storage tank pump. The top of the distillation kettle is connected to a condenser via a distillation tower. The condenser is connected to an alcohol-water separation tank via cooler A. The bottom of the distillation kettle is connected to cooler B via a waste alcohol pump. Cooler B is connected to the alcohol separation tank via a pipeline from the cooler to the alcohol separation tank. This device achieves efficient separation of alcohol and water by utilizing the differences in component volatility through multi-stage separation by the distillation tower and the synergistic effect of the condenser and cooler. Simultaneously, it removes byproducts such as ethers and heavy components. The recovered alcohol exhibits a significantly reduced color and its purity meets production reuse standards, effectively solving the problem of poor quality in traditional recovered alcohol and preventing the impact of alcohol quality issues on DBP product quality.
