Abstract
Description
Technical Field
[0001] This utility model relates to the field of recycling equipment technology, specifically a plasticizer collection and recycling device. Background Technology
[0002] Plasticizers, also known as plasticizers, are an important class of chemical additives that can be added to polymer materials to increase their plasticity. During processing or use, plasticizers evaporate from the surface of the plasticized system and dissipate into the air, and their volatility increases with rising temperature.
[0003] Air containing plasticizers can harm human health when inhaled, and it can also pollute the natural environment and damage the ecosystem. Utility Model Content
[0004] The purpose of this invention is to provide a plasticizer collection and recycling device that can filter and collect air containing plasticizers from an air intake device, thereby avoiding harm to human health and the ecosystem.
[0005] To achieve the above objectives, a plasticizer collection and recycling device is provided, comprising a housing, an interior chamber, an air inlet pipe fixedly connected to one end of the housing, the air inlet pipe being located at the top of the chamber and communicating with the chamber, a refrigeration mechanism fixedly connected to the upper end of the air inlet pipe, the refrigeration mechanism including an evaporator located inside the air inlet pipe and fixedly connected to the inner wall of the air inlet pipe, an air blower fixedly connected to the inner wall of the air inlet pipe, the air blower being located on the side of the evaporator away from the chamber, an air outlet located at the middle of one end of the housing, the air outlet being away from the air inlet pipe, an activated carbon filter fixedly connected to one end of the housing, the input end of the activated carbon filter communicating with the chamber through the air outlet, a demisting mechanism located inside the chamber, the two ends of the demisting mechanism being slidably connected to the inner wall of the chamber, the upper end of the demisting mechanism penetrating upward through the housing and extending to the upper end of the housing, a bolt located at the upper end of the demisting mechanism, and the demisting mechanism being fixedly connected to the housing by the bolt, and a support leg fixedly connected to the lower end of the housing. It can filter and collect air containing plasticizers in intake devices, preventing harm to humans and ecosystems.
[0006] According to the aforementioned plasticizer collection and recovery device, the demisting mechanism comprises a mounting plate, a frame, a demisting filter, and a fixing plate. The mounting plate is located at the upper end of the equipment casing. The frame is fixedly connected to the lower middle part of the mounting plate, extending downwards through the equipment casing and into the chamber. The frame is slidably connected to the side wall of the chamber. The demisting filter is fixedly connected to the inner wall of the frame. The fixing plate is fixedly connected to both ends of the mounting plate, with bolts located at the upper end of the fixing plate and extending downwards through it. The demisting filter adsorbs and collects water mist in the exhaust gas, further drying the air and improving the filtration and collection effect of plasticizers.
[0007] According to the aforementioned plasticizer collection and recovery device, the lower end of the de-misting filter extends below the air inlet pipe. This ensures that the exhaust gas entering the device completely passes through the de-misting filter, guaranteeing a drying effect on the exhaust gas.
[0008] According to the aforementioned plasticizer collection and recovery device, U-shaped guide rails are symmetrically fixedly connected to the side walls of the chamber, and the frame extends into the guide rails and is slidably connected to them. The guide rails limit the movement of the demisting mechanism, reducing vibrations generated within the device during operation.
[0009] According to the aforementioned plasticizer collection and recovery device, an exhaust fan is fixedly connected to the end of the activated carbon filter furthest from the device casing, and the exhaust fan is connected to the output end of the activated carbon filter. The exhaust fan draws air from the device to the outside, increasing the gas flow rate within the device and ensuring recovery efficiency.
[0010] According to the aforementioned plasticizer collection and recovery device, a transparent glass liquid level observation window is provided in the middle of the side end of the device housing, and the liquid level observation window is connected to the chamber. The liquid level of the collected liquid containing plasticizer is observed through the liquid level observation window.
[0011] According to the aforementioned plasticizer collection and recycling device, a drain pipe is fixedly connected to the lower middle part of the device housing, and the drain pipe communicates with the chamber. A solenoid valve is installed in the drain pipe. The liquid containing plasticizer collected in the device is discharged through the drain pipe, facilitating subsequent processing of the plasticizer.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the exhaust gas containing plasticizer is drawn into the device by the air intake fan, the evaporator in the refrigeration mechanism condenses and liquefies the water vapor in the exhaust gas and adsorbs the plasticizer, which is then collected in the chamber, and the activated carbon filter further adsorbs and filters the plasticizer in the exhaust gas.

An air intake fan 10 is fixedly connected to the inner wall of the air inlet pipe 2, and the air intake fan 10 is located on the side of the evaporator 11 away from the chamber 14. An air outlet 15 is provided in the middle of one end of the equipment casing 3, and the air outlet 15 is away from the air inlet pipe 2. An activated carbon filter 6 is fixedly connected to one end of the equipment casing 3, and the input end of the activated carbon filter 6 communicates with the chamber 14 through the air outlet 15. An exhaust fan 7 is fixedly connected to the end of the activated carbon filter 6 away from the equipment casing 3, and the exhaust fan 7 communicates with the output end of the activated carbon filter 6. The exhaust fan 7 draws the air in the device to the outside, increases the gas flow rate in the device, and ensures the recovery efficiency. The chamber 14 is equipped with a demisting mechanism 8, and both ends of the demisting mechanism 8 are slidably connected to the inner wall of the chamber 14. The upper end of the demisting mechanism 8 extends upward through the equipment housing 3 and to the upper end of the equipment housing 3.

The frame 17 is fixedly connected to the middle of the lower end of the mounting plate 16, and the frame 17 extends downward through the equipment housing 3 and into the chamber 14.

[0022] Working principle: During use, the inlet fan 10 draws the waste gas containing plasticizer into the device through the inlet pipe 2, and the exhaust fan 7 extracts the air from the device. When the waste gas containing plasticizer passes through the evaporator 11 in the inlet pipe 2, the water vapor in it condenses and liquefies upon cooling. The liquefied condensate adsorbs the plasticizer in the waste gas. The liquefied condensate flows into the chamber 14. The dried waste gas passes through the demisting mechanism 8 in the chamber 14. The demisting filter 18 adsorbs the water mist carried in the waste gas, drying the waste gas again. The further dried waste gas enters the activated carbon filter 6 through the outlet 15 for filtration, adsorbing the plasticizer in the waste gas.
