Description

Technical Field

[0001] This utility model belongs to the field of chemical industry, and in particular relates to a safe discharge device for a reaction vessel. Background Technology

[0002] Our company uses reactors for esterification reactions. The agitator inside the reactor usually needs to stir continuously, and material often accumulates at the bottom outlet. Due to the height and pressure of the reactor, the solid deposits in the discharge pipe are continuously compressed during the stirring process. As a result, when the reaction in the esterification reactor is completed and discharge is required, even if the discharge valve is opened, the material cannot be discharged in time, which inadvertently affects the factory's production schedule.

[0003] Chinese utility model patent application number 2021233767077 discloses a reactor discharge pipe that uses a continuously rotating drive motor to repeatedly impact the main pipe, thereby creating a vibration effect to prevent clogging. However, this vibration only allows the material inside to be discharged quickly, while the material adhering to the inner wall cannot be effectively discharged, failing to completely solve the discharge problem. Summary of the Invention

[0004] In view of this, the present invention aims to overcome the defects in the prior art and propose a safe discharge device for a reaction vessel.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A safe discharge device for a reaction vessel includes a reaction vessel, a stirring mechanism on the reaction vessel, a discharge port at the bottom of the reaction vessel, an anti-blocking mechanism at the discharge port, and the stirring mechanism connected to the anti-blocking mechanism.

[0007] The anti-blocking mechanism includes a bearing frame and two identical connecting sleeves. The bearing frame is located between the connecting sleeves, which are arranged opposite to each other. The connecting sleeves are respectively connected to the discharge port and the discharge pipe.

[0008] Furthermore, a fixing frame is provided on the inner side of the bearing bracket, and a plurality of anti-blocking units are provided on the fixing frame.

[0009] Furthermore, the anti-clogging unit includes a fixed base, a fixed shaft, and an anti-clogging scraper. The fixed base is fixed to the inner side of the fixed frame, the fixed shaft is located on the fixed base, and the anti-clogging scraper is connected to the fixed shaft. The length of the anti-clogging scraper is greater than the height of the connecting sleeve, which facilitates the treatment of the inner wall of the discharge port.

[0010] Furthermore, the anti-clogging scraper includes a connecting plate, with scraper blades at both ends. The connecting plate has an arc-shaped structure, and its center is located inside the fixed frame. The arc-shaped structure of the connecting plate reduces the impact of materials, improves its service life, and better scrapes away clogged materials during rotation.

[0011] Furthermore, the connecting plate is inclined, with the end of one of the scrapers adjacent to the inner side of the connecting sleeve. The tangent direction of the scraper and the connecting sleeve forms an acute angle, which scrapes away the blockage on the inner side of the connecting sleeve during rotation, improving the safety of material discharge.

[0012] Furthermore, the stirring mechanism includes a rotary motor, a rotating shaft, and a stirring paddle. One end of the rotating shaft is placed inside the reaction vessel and connected to the anti-clogging mechanism, while the other end is connected to the rotary motor. The stirring paddle is located on the rotating shaft and above the anti-clogging mechanism.

[0013] Furthermore, a connecting frame is provided on the fixed frame, and the fixed frame is connected to the rotating shaft through the connecting frame. The rotating shaft drives the bearing bracket to rotate through the connecting frame. The bearing bracket can be a ball bearing, and a fixed frame is provided on the inner ring of the ball bearing, allowing the inner ring to rotate relative to the outer ring.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] The safe discharge device for the reactor described in this utility model connects the rotating shaft of the stirring mechanism with the anti-blocking mechanism. The rotating shaft drives the anti-blocking mechanism to rotate at the discharge port to prevent material from clogging at the discharge port. At the same time, it can scrape off the material adhering to the sleeve and the inner wall of the discharge port, thereby improving the safety of the reactor. Attached Figure Description

The connecting plate 1261 is inclined, with the end of one scraper adjacent to the inner side of the connecting sleeve 121. The scraper forms an acute angle with the tangent direction of the connecting sleeve 121. When rotating, it scrapes away the blockage inside the connecting sleeve 121, improving the safety of material discharge.
