Description

Technical Field

[0001] This utility model relates to the field of high-pressure reactor technology, specifically a high-pressure reactor with a filtration device. Background Technology

[0002] The high-pressure reactor is a typical innovation of applying magnetic drive devices to large-scale reaction equipment. It fundamentally solves the shaft seal leakage problem that previous packing seals and mechanical seals could not overcome. It has no leakage or pollution and is currently the most ideal device in China for carrying out chemical reactions under high temperature and high pressure. In particular, it shows its superiority in carrying out chemical reactions of flammable, explosive and toxic media.

[0003] The output of existing high-pressure reactors requires further processing such as filtration and impurity removal. This is because impurities precipitate during the reaction inside the reactor, which are usually intercepted and filtered by the filter plates inside the reactor. However, after processing, the impurities on the filter plates need to be cleaned. Moreover, a lot of waste residue is filtered out during the filtration process, which can easily clog the filter components. Most reactors on the market require the lid to be opened and the filter plates to be manually removed and cleaned. The cleaning process is quite cumbersome, and work can only continue after the filter screen is cleaned, which affects the processing progress of the reactor. Summary of the Invention

[0004] This invention provides a high-pressure reactor with a filtration device, aiming to solve the problems mentioned in the background art, such as the fact that most reactors on the market require opening the reactor lid and manually removing and cleaning the filter plate, which is a cumbersome cleaning process and can only continue working after the filter screen is cleaned, thus affecting the processing progress of the reactor.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-pressure reactor with a filtration device, comprising a reactor body, a feed inlet fixedly installed on one side of the top of the reactor body, a stirring mechanism fixedly connected to the top of the inner side of the reactor body, a discharge port fixedly installed at the bottom of the reactor body, and a filtration device fixedly installed at the bottom of the discharge port; the filtration device comprises a filter cylinder threadedly connected to the bottom of the discharge port, a first filter assembly and a second filter assembly rotatably connected from top to bottom between the inner walls of the two sides of the filter cylinder, a first rotating shaft fixedly connected to one side of the first filter assembly, a first gear fixedly installed at the end of the first rotating shaft, a second rotating shaft fixedly installed to one side of the second filter assembly, a second gear fixedly installed at the end of the second rotating shaft, a mounting plate fixedly installed to one side of the discharge port, an electric push rod fixedly installed at the bottom of the mounting plate, and a rack fixedly connected to the output end of the electric push rod and meshing with the first gear and the second gear respectively; rinsing assemblies are rotatably connected to both the front and rear sides of the filter cylinder.

[0006] In use, the filter device filters the solid residue generated in the reactor body, and the rinsing component can simultaneously rinse the filter device without stopping the discharge, thus preventing clogging and greatly improving the processing speed of the reactor. Specifically, the electric push rod drives the rack to move, and the rack then drives the first gear and the second gear to rotate. The first gear and the second gear drive the first filter component and the second filter component to rotate 90 degrees through the first rotating shaft and the second rotating shaft, respectively, realizing the alternating filtration work of the first filter component and the second filter component. Furthermore, the rinsing component can simultaneously rinse the first filter component or the second filter component that is not filtering, thereby significantly improving work efficiency.

[0007] Preferably, the rinsing assembly includes two rinsing pipes rotatably connected to one side of the filter cylinder and corresponding to the first filter assembly and the second filter assembly respectively, a rinsing head fixedly connected to the end of the rinsing pipe and parallel to the second filter assembly, a plurality of rinsing nozzles evenly distributed on the surface of the rinsing head, two pulleys fixedly installed on the outside of the rinsing pipes respectively, a timing belt fixedly installed on the outside of the two pulleys, and a drive mechanism for driving the pulleys to rotate.

[0011] Preferably, a guide rod is fixedly installed on one side of the filter cartridge, and a slider that is slidably connected to the guide rod is fixedly installed on the back of the rack.

[0012] Preferably, both ends of the flushing pipes are fixedly connected to an external water pipe.

[0013] This high-pressure reactor with a filtration device has a simple structure and is easy to use. The filtration device filters solid residues generated in the reactor body, and the rinsing component can simultaneously rinse the filtration device without stopping the discharge, thus preventing clogging and greatly improving the processing speed of the reactor. Specifically, an electric push rod drives a rack to move, which in turn drives a first gear and a second gear to rotate. The first gear and the second gear drive the first filter assembly and the second filter assembly to rotate 90 degrees through a first rotating shaft and a second rotating shaft, respectively, realizing the alternating filtration work of the first filter assembly and the second filter assembly.
