Description

Technical Field

[0001] This utility model relates to the field of high-pressure reactor technology, specifically a high-pressure reactor that facilitates the cleaning of residual liquid. Background Technology

[0002] An autoclave, also known as a high-pressure reactor, is an essential container in chemical plants for producing chemical products. Reactors can achieve heating, evaporation, cooling, and low-to-high-speed mixing functions as required by the process. They are widely used in chemical, pharmaceutical, and materials research fields. During use, reactant and product residues adhere to the inner liner; therefore, regular cleaning of the inner liner is crucial for maintaining normal operation and extending the lifespan of the instrument. Industrially, autoclaves are devices that conduct chemical reactions under high pressure. Some are equipped with stirring or heat transfer devices and are also called pressure vessels. An autoclave consists of a reaction vessel, a stirrer and transmission system, a cooling system, safety devices, and a heating furnace.

[0003] Chinese patent publication number "CN 219898165 U" discloses a "chemical reactor that is easy to clean," comprising a reactor body with multiple support legs fixed to the bottom. A discharge pipe with a valve is located at the bottom of the reactor body, and a feed inlet is located on one side of the top. A cleaning mechanism with a fixing mechanism is located within the reactor body. The cleaning mechanism includes a rotatable fixed shaft positioned in the middle of the reactor body. After the cleaning brush wears down, it pulls the brush towards the top of the reactor body. A limiting ball slides within an arc-shaped groove and is compressed by the change in the groove's depth, causing the spring to compress and move the limiting ball into the limiting groove, thus losing its restriction on the limiting protrusion. The cleaning brush can then be removed and replaced, reducing the time and steps required for brush replacement.

[0004] This patent addresses the issue that existing internal cleaning brushes in reactors can only rotate along the same horizontal line when cleaning the inner wall. This cleaning method leads to dead corners between the upper and lower sets of cleaning brushes, which can cause ring-shaped deposits to form over time, affecting subsequent reactions and shortening the service life of the reactor. Furthermore, the reactor only uses a motor to drive the cleaning brushes for cleaning, resulting in a single cleaning method and poor cleaning effect. Therefore, we propose a high-pressure reactor that facilitates the cleaning of residual liquids. Utility Model Content

[0005] The purpose of this invention is to provide a high-pressure reactor that facilitates the cleaning of residual liquids, in order to solve the problems mentioned in the background art, where the internal cleaning brush of the reactor can only rotate along the same horizontal line when cleaning its inner wall, which will eventually lead to the formation of ring-shaped deposits, affecting subsequent reactions and shortening the service life of the reactor. Furthermore, the reactor only uses a motor to drive the cleaning brush for cleaning, resulting in a single cleaning method and poor cleaning effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-pressure vessel for easy cleaning of residual liquid, comprising a mounting frame, a vessel body fixedly connected to the top of the mounting frame, a vessel cover connected to the top of the vessel body, a lower flange provided at the upper surface of the vessel body, an upper flange provided at the lower surface of the vessel cover, the vessel body and the vessel cover being fixedly connected by the upper flange, the lower flange and bolts, and a water outlet pipe provided at the bottom of the vessel body.

[0007] Preferably, the upper surface of the vessel lid is provided with a water inlet pipe, one end of which is connected to the top side of the water storage pipe, a connecting pipe is fixedly connected to the inner arc surface of the water storage pipe, and a water spray nozzle is fixedly connected to the bottom of the connecting pipe, and the connecting pipe is configured as an L-shaped structure.

[0008] Preferably, a connecting box is fixedly connected to the top of the vessel lid, a drive motor is fixedly connected to the top of the connecting box, and a rotating disk is connected to the output end of the drive motor.

[0009] Preferably, a rotating disk is connected inside the connecting box, an outer bushing is fixedly connected to the bottom of the rotating disk, a sliding groove is provided on the side wall of the outer bushing, an inner shaft is connected through the outer bushing, a push rod is provided on the inner shaft, an electric telescopic rod is fixedly connected to the top of the push rod, and the other end of the electric telescopic rod is fixedly connected to the lower surface of the rotating disk.

[0010] Preferably, the rotating disk is rotatably connected to the connecting box via a bearing, and the connecting box is provided with a through hole for connection to the output end of the drive motor.

[0011] Preferably, the inner shaft has two horizontal bars on its side wall, the other end of each horizontal bar is fixedly connected to a vertical plate, a reinforcing bar is fixedly connected between the horizontal bars, and a diagonal bar is fixedly connected between the reinforcing bar and the vertical plate.

[0012] Preferably, a side wall scraper is fixedly connected to the side of the vertical plate, and a bottom arc-shaped scraper is fixedly installed at the bottom of the inner shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This high-pressure autoclave, which facilitates the cleaning of residual liquid, uses a drive motor to rotate a rotating disk, which in turn rotates the outer bushing and inner shaft. The electric telescopic rod moves up and down, causing the push rod to move up and down within the chute. This, in turn, causes the inner shaft, side wall scraper, and arc-shaped scraper to move up and down within the outer bushing, effectively increasing the stirring amplitude and improving the cleaning effect.

[0015] 2. This high-pressure autoclave, which facilitates the cleaning of residual liquids, connects an external water pipe to the inlet pipe while the equipment is running. The water flows through the inlet pipe into the storage pipe and is finally sprayed out from the nozzle to rinse the inner wall of the autoclave. The combination of multiple cleaning methods makes the cleaning effect better. Attached Figure Description
