Description

Technical Field

[0001] This utility model relates to the field of o-cresol production, and in particular to an electronic-grade o-cresol purification device. Background Technology

[0002] o-Cresol is mainly used in the synthesis of resins, herbicides, disinfectants, preservatives, plasticizers, and fragrances. o-Cresol reacts with formaldehyde to produce cresol-formaldehyde resin, which is further reacted with epichlorohydrin to prepare epoxy-cresol-formaldehyde resin. ECN is mainly used as a curing agent for epoxy model compounds in electronic components, especially computer components. In the electronics industry, ECN serves as a transfer model compound, particularly for integrated circuit block packaging and plastic sheets. ECN can also be used in functional powder coatings for pipe fittings and in oil and gas extraction in oil fields. The domestic market demand is huge, and the development potential is significant.

[0003] During the continuous distillation process in the crude phenol refining unit, the high content of impurities such as 2,6-xylenol and naphthalene in the raw material leads to a high level of o-cresol neutral oil, resulting in low purity and easy discoloration. Utility Model Content

[0004] The purpose of this invention is to provide an electronic-grade o-cresol purification device to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an electronic-grade o-cresol purification device, comprising an ultrasonic-assisted extraction tank, an ultrasonic probe, a raw material filter box, a filter element, a fixing plate, a raw material inlet, an extractant inlet, a motor, a cavitation-inducing stirring shaft, and a continuous distillation column. The ultrasonic probe is distributed on the side of the ultrasonic-assisted extraction tank. The raw material filter box is installed at the top of the side of the ultrasonic-assisted extraction tank. The filter element is installed inside the raw material filter box. The fixing plate is fixed to the opening of the raw material filter box. The raw material inlet is located at the top of the raw material filter box. The extractant inlet is located at the front of the raw material filter box via the ultrasonic-assisted extraction tank. The motor is installed at the rear of the ultrasonic-assisted extraction tank. The cavitation-inducing stirring shaft is installed inside the motor via the ultrasonic-assisted extraction tank. The continuous distillation column is connected to the extractant outlet of the ultrasonic-assisted extraction tank.

[0006] Based on the above technical solution, the cavitation-induced stirring shaft includes a shaft body, a support, a stirring paddle, and enhancement serrations. The shaft body is installed inside the ultrasonic-assisted extraction tank at the output end of the motor equipment. The support is fixed to the side end of the shaft body, the stirring paddle is fixed to the support, and the enhancement serrations are distributed at both the inner and outer ends of the stirring paddle.

[0007] Based on the above technical solution, the stirring paddle uses the Bernoulli principle to form a local low-pressure zone in the o-cresol raw material through the rotational enhanced serrations, which superimposes the negative pressure phase of the ultrasonic waves generated by the ultrasonic probe, making it easier to generate cavitation bubbles.

[0008] Compared with existing technologies, this invention has the following advantages: In the pretreatment stage of o-cresol before continuous distillation, a cavitation-inducing stirring shaft is installed in an ultrasonic-assisted extraction tank equipped with an ultrasonic probe. The enhanced serrations of the stirring paddle utilize Bernoulli's principle to create a local low-pressure zone, which superimposes with the negative pressure phase of the ultrasonic waves generated by the probe, making cavitation bubbles easier to form. This enhances the separation efficiency of the target component o-cresol from impurities in the raw material, providing a purer feed for subsequent distillation processes. It also improves the purity of o-cresol. Attached Figure Description

Detailed Implementation

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] like Figures 1 to 4 As shown, an electronic-grade o-cresol purification device includes an ultrasonic-assisted extraction tank 1, an ultrasonic probe 2, a raw material filter box 3, a filter element 4, a fixing plate 5, a raw material inlet 6, an extractant inlet 7, a motor 8, a cavitation-induced stirring shaft 9, and a continuous distillation column 10. The ultrasonic probe 2 is distributed on the side of the ultrasonic-assisted extraction tank 1. The raw material filter box 3 is installed at the top of the side of the ultrasonic-assisted extraction tank 1. The filter element 4 is installed inside the raw material filter box 3. The fixing plate 5 is fixed to the opening of the raw material filter box 3. The raw material inlet 6 is located at the top of the raw material filter box 3. The extractant inlet 7 is located at the front of the raw material filter box 3 through the ultrasonic-assisted extraction tank 1. The motor 8 is installed at the rear of the ultrasonic-assisted extraction tank 1. The cavitation-induced stirring shaft 9 is installed inside the ultrasonic-assisted extraction tank 1. The continuous distillation column 10 is connected to the extractant outlet of the ultrasonic-assisted extraction tank 1.

[0016] The cavitation-induced stirring shaft 9 includes a shaft body 11, a support 12, a stirring paddle 13, and enhancement serrations 14. The shaft body 11 is installed inside the ultrasonic-assisted extraction tank 1 at the output end of the motor device 8. The support 12 is fixed to the side end of the shaft body 11, the stirring paddle 13 is fixed to the support 12, and the enhancement serrations 14 are distributed at both the inner and outer ends of the stirring paddle 13.

[0017] The stirring paddle 13, through the rotational enhancement sawtooth 14 within the o-cresol raw material, utilizes Bernoulli's principle to create a local low-pressure zone that superimposes with the negative pressure phase of the ultrasonic waves generated by the ultrasonic probe 2, making cavitation bubbles easier to generate.

[0018] The working principle of this invention is as follows: o-cresol raw material is poured into the raw material filter box 3 through the raw material inlet 6. After being filtered by the filter element 4 to remove solid impurities, the raw material enters the ultrasonic-assisted extraction tank 1. Extraction liquid is poured in through the extraction liquid inlet 7. The motor device 8 and the ultrasonic probe 2 are started. The ultrasonic probe 2 emits ultrasonic waves that act on the raw material and the extraction liquid inside the ultrasonic-assisted extraction tank 1. The shaft 11 rotates the support 12 as driven by the motor device 8. The stirring paddle 13 rotates within the o-cresol raw material through the serrated teeth 14, utilizing Bernoulli's principle to create a local low-pressure zone. This zone is superimposed with the negative pressure phase of the ultrasonic waves generated by the ultrasonic probe 2, making it easier to generate cavitation bubbles. This enhances the separation efficiency of the target component o-cresol from impurities in the raw material. The extracted phase enters the continuous distillation column 10 through the outlet for distillation, providing a purer feed for subsequent distillation processes. This improves the purity of o-cresol.

[0019] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
