Description

Technical Field

[0001] This utility model relates to the field of chemical production technology, specifically to a reaction device for continuous esterification of waste oils. Background Technology

[0002] In daily life, a large amount of waste oil is often generated, such as high-acid-value kitchen waste oil and swill oil. Direct discharge will not only waste resources but also pollute the environment. At present, biodiesel can be produced by esterification of waste oil. Its excellent performance has attracted more and more attention. Esterification methods of waste oil include warm sulfuric acid catalytic methanol vapor phase esterification and high-temperature catalyst-free methanol vapor subcritical esterification.

[0003] According to Chinese Patent CN218262411 U, a reaction apparatus for continuous esterification of waste oil is provided. The presence of a temperature control unit allows for temperature regulation within the apparatus, ensuring the internal temperature remains within the required reaction temperature range for the waste oil esterification reaction. This guarantees the thorough esterification process and thus the quality of the esterification. Furthermore, the presence of a waste oil supply unit allows for the filtration and purification of the waste oil while ensuring its continuous supply. This prevents impurities from entering the reaction area, effectively guaranteeing the quality of the esterification product.

[0004] The above-mentioned device cannot be replaced or disassembled in time if the heating tube is damaged after a period of use when it is installed in the inner wall of the shell, which reduces the convenience of the device and affects the working efficiency of the reaction. Therefore, a reaction device for continuous esterification of waste oil is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a reaction device for continuous esterification of waste oils. It has the advantages of allowing the heating tube to be removed from the inner wall of the shell for replacement after damage, ensuring that the efficiency of subsequent reaction work is not affected. This solves the problem that when the heating tube is installed in the inner wall of the shell, it cannot be replaced or disassembled in time if it is damaged after a period of use, which reduces the convenience of the device and affects the efficiency of the reaction.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a reaction device for continuous esterification of waste oil, comprising a shell, wherein a cover plate is detachably connected to the top of the shell, and a replacement component is provided on the outer surface of the cover plate;

[0007] The replacement component includes an annular groove plate, which is fixedly connected to the bottom of the cover plate. A heating tube body is fixedly connected inside the annular groove plate. A connecting plate is fixedly connected to the bottom of the cover plate. Mounting plates are fixedly connected to both the left and right sides of the housing. A mounting base is fixedly connected to the top of the cover plate. Two positioning posts are fixedly connected inside the mounting base. Filter cylinders are movably connected to the outer surfaces of the two positioning posts. A filter screen sleeve is placed inside the filter cylinder. A sealing plate is detachably connected to the top of the filter cylinder.

[0008] Furthermore, an annular cavity is provided inside the housing, and the annular groove plate is located inside the housing through the annular cavity. An annular pressure plate is fixedly connected to the bottom of the cover plate, and the annular pressure plate is sealed to the inside of the housing.

[0009] Furthermore, both mounting plates are internally threaded with first bolts, and the connecting plate is detachably connected to the two mounting plates via the two first bolts.

[0010] Furthermore, the mounting base has an internal mounting groove, through which the filter cartridge is located inside the mounting base, and the filter screen sleeve is adapted to the size of the filter cartridge.

[0011] Furthermore, both sides of the mounting base can be detachably connected to limit plates, and both limit plates are internally threaded with second bolts.

[0012] Furthermore, the sealing plate is engaged with two positioning posts, and both sides of the sealing plate are detachably connected to two second bolts via two limiting plates.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. In this continuous esterification waste oil reaction device, when the heating tube body is installed, it is placed inside the annular groove plate and fixed. Then, the cover plate is pressed onto the top of the shell by the annular pressure plate, and then the first bolt is tightened to fix it. When cleaning the filter cylinder, the second bolt is tightened to detach the sealing plate from the mounting base. Then, the filter cylinder is separated from the two positioning columns, and the filter screen inside the filter cylinder is removed for cleaning and replacement, so that the quality of subsequent reactions is not affected.

[0015] 2. This continuous esterification waste oil reaction device, by setting two positioning columns inside the mounting base, positions the filter cartridge on the outer surface of the two positioning columns, ensuring a more secure seal when the sealing plate is pressed tightly, and also paving the way for subsequent cleaning of the filter cartridge. By setting a filter screen sleeve, impurities in the esterified waste oil can be filtered out during the reaction, ensuring better reaction quality. Attached Figure Description
