Description

A self-cleaning reactor

technical field

The utility model relates to the field of reactor equipment, in particular to a self-cleaning reactor.

Background technique

The reaction kettle is a stainless steel container with physical or chemical reactions. The structural design and parameter configuration of the container are carried out according to different process conditions. The design conditions, process, inspection, manufacturing, and acceptance must be based on relevant technical standards to achieve heating, Evaporation, cooling and low-speed mixing reaction functions.

Existing authorized notification number is that the Chinese patent of CN204724154U discloses a kind of double agitator reactor, and it comprises reactor body, jacket, rotating shaft, outlet, baffle plate, kettle cover, feeding port and motor. The reactor body is divided into two parts, the upper reactor body and the lower reactor body. The lid is located above the upper reactor body. The upper reactor body is connected and sealed with the lower reactor body. The baffle is located on the inner wall of the reactor body. It is integrated with the reactor body through fixed connectors. The jacket is located outside the reactor, the rotating shaft is installed in the center of the upper reactor body, the upper end is connected with the motor, and the lower end extends into the lower reactor body to connect with the lower agitator; the feeding port is located at the upper end of the upper reactor body, The discharge port is located at the lower end of the lower reactor body, and the feeding port is located at the upper part of the kettle cover.

However, when the rotating shaft is stirring, there is a distance between the agitator and the inner wall of the kettle body, and the BU series acrylic polyurethane in the kettle body will partially adhere to the inner wall of the kettle body. As a result, the agitator has some dead corners that cannot be cleaned, so that the BU series acrylic polyurethane in the kettle body accumulates in the dead corners, which is not conducive to the reaction of the BU series acrylic polyurethane.

Utility model content

Aiming at the deficiencies in the prior art, the purpose of this utility model is to provide a self-cleaning reaction kettle, which has the advantage of cleaning the BU series acrylic polyurethane adhered to the inner wall of the kettle during the reaction.

In order to achieve the above object, the utility model provides the following technical solutions:

A self-cleaning reaction kettle, comprising a kettle body, a kettle cover arranged above the kettle body, and a rotating shaft arranged inside the kettle body, a number of rotating blades are arranged on the outer wall of the rotating shaft, and a number of rotating blades are arranged on the inner wall of the kettle cover. There is a driving gear, and the inner wall of the kettle body is rotated to be provided with a driven gear meshing with the driving gear; the inner wall of the kettle body is provided with a rib contacting the lower end surface of the driven gear; the driven gear’s The lower end surface is provided with a fixed plate, and the fixed plate is provided with a first scraper in contact with the inner wall of the kettle body.

By adopting the above technical scheme, when the rotating shaft drives the rotating blade to rotate, the rotating blade will stir the BU series acrylic polyurethane placed inside the kettle body so that it can fully react. When the rotating shaft is working, the driving gear will drive the driven gear meshed with it to rotate when the driving gear rotates, so that the fixed plate fixed on the lower end surface of the driven gear will rotate together with the driven gear. Because the first scraper that is in contact with the inner wall of the still body is arranged on the fixed plate, the first scraper contacts the inner side wall of the still body when the fixed plate is rotating, thereby removing the scraper that adheres to the inner wall of the still body. BU Series Acrylic Urethane Clean Down.

Furthermore, ribs are provided on the inner wall of the kettle body, and grooves matching the ribs are provided on the driven gear.

By adopting the above technical solution, the position of the driven gear along its axial direction can be limited through the cooperation of the rib and the groove, thereby reducing the movement of the position of the driven gear when cleaning the inner wall of the kettle.

Further, the lower end of the rotating shaft is provided with an extension rod, and the extension rod is provided with several second scrapers in contact with the bottom wall of the kettle body.

By adopting the above technical proposal, the rotating shaft drives the second scraper to clean the inner wall of the kettle body, thereby improving the cleaning effect of the kettle body.

Further, the second scraper is detachably connected to the extension rod.

By adopting the above technical solution, the second scraper is detachably connected to the extension rod, which facilitates maintenance and replacement of the second scraper.

Further, the end surface of the second scraper in contact with the bottom wall of the kettle body is provided with a protective pad.

By adopting the above technical solution, the protective pad avoids the direct contact between the second scraper and the bottom wall of the kettle body, thus having a certain protective effect on both the kettle body and the second scraper.

Further, a water flow channel is opened on the second scraper.

By adopting the above technical scheme, the BU series acrylic polyurethane can flow from the inside of the water flow channel under the agitation of the rotating shaft. Thereby reducing the influence of the second scraper on the BU series acrylic polyurethane reaction in the still body.

Further, a nail plate is arranged on the outer wall of the rotating shaft, and a plurality of defoaming needles are arranged on the lower end surface of the nail plate.

By adopting the above technical scheme, during the reaction process of BU series acrylic polyurethane, it will generate bubbles under the stirring of the rotating shaft, and the bubbles will be pierced by the defoaming needle when they rise to the upper end of the liquid surface. Thereby reducing the adverse effect of air bubbles contained inside the BU series acrylic polyurethane on its subsequent use.

Further, a number of balls are embedded in the end surface of the sidewall close to the driven gear.

By adopting the above technical solution, the ball transforms the sliding friction between the rib and the driven gear into rolling friction between the ball and the driven gear, thereby reducing the frictional resistance when the driven gear rotates.

In summary, the utility model has the following beneficial effects:

1. Clean the inner wall of the kettle body by setting the driving gear, driven gear, fixed plate and first scraper;

2. By setting the extension rod, the second scraper and the water flow channel, the inner bottom wall of the kettle body is cleaned.
