Technical Field

[0001] This utility model relates to the field of modified silicone oil processing technology, and in particular to an internal cleaning device for a modified silicone oil reactor. Background Technology

[0002] The preparation of alkyl-modified silicone oil also needs to be carried out in a reaction vessel. Currently, in the production process of alkyl-modified silicone oil, oxygen is often mixed into the reaction vessel during the addition of materials. During the reaction, the oxygen participates in the oxidation reaction, which causes the produced product to have an off-color and the quality to decline. How to simply and quickly reduce the oxygen content in the reaction vessel has become the key to the quality of the alkyl-modified silicone oil produced.

[0003] A search revealed that prior art CN204841666U discloses a modified silicone oil reactor, including an inlet pipe and an outlet pipe connected to the upper and lower ends of the reactor body, respectively. It also includes a stirrer installed at the upper end of the reactor body. An exhaust pipe is connected to the upper end of the reactor body, and an inlet pipe is connected to the outlet pipe. The inlet pipe is inclined downwards and connected to the outlet pipe. Valves are installed on both the inlet and exhaust pipes. The end of the inlet pipe is connected to a nitrogen tank, and the end of the exhaust pipe is connected to a vacuum pump. This invention, by providing an exhaust pipe and an inlet pipe on the reactor body and filling the reactor with nitrogen before extraction, reduces the oxygen content inside the reactor, thus solving the problem of product quality degradation caused by oxygen participating in the modified silicone oil production reaction.

[0004] The above equipment has the following problems when in use: the internal agitator blades and the inner wall of the reactor body are inconvenient to clean. Utility Model Content

[0005] The purpose of this invention is to provide an internal cleaning device for a modified silicone oil reactor, which aims to solve the problem of inconvenient internal cleaning of existing reactors.

[0006] To achieve the above objectives, this utility model provides an internal cleaning device for a modified silicone oil reactor, including a reactor body, a stirring mechanism inside the reactor body, a discharge valve at the bottom, a feeding mechanism at the top, and a cleaning mechanism.

[0007] The cleaning mechanism includes a main pipe, a delivery pipe, an abutment pipe, a filter seat, a filter cylinder, a one-way valve, an inlet pipe, a connecting pipe, an arc-shaped scraper, and a side wall scraper. The main pipe is located at the top of the reactor body. The delivery pipe is welded to the water outlet side of the main pipe. The abutment pipe is slidably installed in a water-passing seat at the top of the reactor body. The water-passing seat is detachably installed at the top of the reactor body. The filter seat is installed on the water inlet side of the main pipe. The filter cylinder is located inside the filter seat, and its filter screen has a high-temperature resistant coating on its outer surface.

The support column is welded to the top detachable cover plate of the reactor body and three of them are arranged in a ring at intervals. The protective plate is fixedly connected to the support column and is located on top of the support column.

[0012] This invention relates to an internal cleaning device for a modified silicone oil reactor. When the reactor body needs internal cleaning, firstly, the threaded end cap at the top of the water inlet is removed. Then, the mounting plate at the bottom of the main pipe is fixed to the reactor body with bolts. During the installation of the main pipe, the abutment pipe must be inserted into the water inlet.

The filter seat 106 is installed on the water inlet side of the main guide pipe 103. The filter cylinder 107 is disposed in the filter seat 106, and its filter screen outer surface is provided with a high-temperature resistant coating. The inlet pipe 109 is installed on the water inlet side of the filter seat 106. The one-way valve 108 is installed on the filter seat 106. The matching pipe 110 is installed on the top of the one-way valve 108. The arc-shaped scraper 111 and the side wall scraper 112 are respectively installed on both sides and the bottom of the stirring mechanism, and respectively slide in contact with the inner wall of the reactor body 101. The water inlet seat 113 is fixed by bolts. The delivery pipe 104 is welded to the main guide pipe 103. The connecting flange of the delivery pipe 104 is connected to the top flange of the abutment pipe 105 by bolts and nuts. The abutment pipe 105 is provided with a limiting plate, and an installation groove is provided on the outer side of the cylindrical part of the pipe extending into the water inlet seat 113. An installation sealing ring is fitted in the installation groove. The outlet flange of the filter seat 106 is connected to the inlet flange of the main guide pipe 103 by bolts and nuts. The threaded end of the filter cylinder 107 is directly installed on the filter... Inside the mounting cavity of seat 106, the outer surface of the filter screen of filter cylinder 107 is provided with a high-temperature resistant coating to improve its heat resistance and prevent it from deforming in a hot water environment for a long time. The inlet pipe 109 is connected to the filter seat 106 by a screw and nut.

[0026] Then, the stirring motor 115 is fixed to the top of the reactor body 101; the connecting shaft at the top of the stirring frame 116 is connected to the output shaft of the stirring motor 115 via a coupling, and is fixedly connected to the arc-shaped scraper 111 and the side wall scraper 112 respectively.

When installing the main guide pipe 103, the abutment pipe 105 must be inserted into the water inlet seat 113. Furthermore, heated clean water can be delivered into the main guide pipe 103 through the inlet pipe 109. Then, the clean water is delivered into the reactor body 101 through the delivery pipe 104 and the abutment pipe 105. The cleaning process involves cleaning the interior of the reactor body 101, then controlling the rotation of the stirring mechanism to drive the arc-shaped scraper 111 and the side wall scraper 112 to rotate, thereby cleaning the inner wall of the reactor body 101 and the arc-shaped scraper 111 and the side wall scraper 112. At the same time, cleaning fluid can be delivered into the main pipe 103 through the connecting pipe 110, thus combining with hot water to form a cleaning solution. Due to the setting of the one-way valve 108, the cleaning water will not enter the connecting pipe 110 upwards, and the cleaning wastewater can be discharged by opening the discharge valve 102, thereby solving the problem of inconvenient internal cleaning of existing reactors.
