Description

Technical Field

[0001] This invention belongs to the field of benzotriazole preparation technology, and particularly relates to a stirring reaction apparatus for the preparation of benzotriazole. Background Technology

[0002] The preparation of benzotriazole requires stirring in a stirred reactor. In a broad sense, a reactor is a container where physical or chemical reactions occur. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-to-high-speed mixing functions required by the process can be achieved.

[0003] Because the stirring claw structure of conventional reactors is fixed, when cleaning impurities inside, the stirring claw gets stuck inside, hindering the cleaning process. This makes the cleaning operation after shutting down a conventional reactor for the preparation of benzotriazole quite troublesome.

[0004] To address these issues, we propose a stirred reaction apparatus for the preparation of benzotriazole. Utility Model Content

[0005] The purpose of this invention is to solve the problem of cumbersome cleaning operations after shutting down conventional benzotriazole preparation reactors, and to propose a stirring reaction device for benzotriazole preparation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A stirring reaction apparatus for the preparation of benzotriazole includes a motor, an externally fixed cover, a rotating sleeve fixedly connected to the motor rotor, the rotating sleeve being rotatably mounted inside the cover, a transmission rod slidably mounted inside the rotating sleeve, a shaft seat rotatably connected to the lower part of the cover, a booster spring fixedly connected between the shaft seat and the cover, a stirring tank fixedly connected to the lower part of the shaft seat, a rotating frame fixedly connected inside the stirring tank, the upper end of the rotating frame engaging with the transmission rod, a swing plate installed inside the rotating frame, and the cover engaging with the stirring tank cover. After pouring material into the stirring tank and closing the cover and stirring tank, the transmission rod engages with the rotating frame. The motor drives the rotating sleeve to rotate, which in turn drives the transmission rod to rotate, causing the rotating frame to rotate. Centrifugal force causes the swing plate to open outwards, stirring the material inside the stirring tank. When the rotating frame comes to rest, the swing plate retracts into the rotating frame under its own weight, facilitating cleaning of the inside of the stirring tank.

[0008] Preferably, the mixing tank includes a tank body, with baffles uniformly and fixedly connected inside the tank body, and a bearing fixedly connected to the bottom of the tank body. The baffles increase eddy current resistance, thereby ensuring the mixing efficiency of the swing plate, and the bearing guides the rotation of the rotating frame, facilitating the mixing of the target material.

[0009] Preferably, the bearing includes a fixed seat, with a fixed shaft fixedly connected to the upper part of the fixed seat and a limiting plate fixedly connected to the upper part of the fixed seat; the lower part of the fixed seat is fixedly connected to the barrel body. The fixed shaft guides the swing of the lid, and the limiting plate restricts the opening range of the lid, facilitating the opening or closing of the lid.

[0010] Preferably, the cover includes a cover body, a handle is fixedly connected to the upper part of the cover body, and a swing arm is fixedly connected to the outside of the cover body; the lower part of the swing arm is rotatably mounted on a fixed shaft, one end of the assist spring is fixedly connected to the swing arm, the other end of the assist spring is fixedly connected to the fixed shaft, and the motor is fixedly connected to the swing arm. The spring force of the assist spring acts on the swing arm, which in turn acts on the cover body, reducing the force required to open the cover. Simultaneously, the spring force of the assist spring maintains the cover in the open state, facilitating manual operation of the cover.

[0011] Preferably, the rotating sleeve includes a sleeve body with a sliding groove; the sleeve body is fixedly connected to the rotor of the motor, and the sleeve body is rotatably installed inside the cover. The sliding groove guides the transmission rod to slide; when the transmission rod and the rotating frame are misaligned, the transmission rod retracts along the sliding groove until they are aligned, at which point the transmission rod returns to its original position and engages with the rotating frame, facilitating the connection between the transmission rod and the rotating frame.

[0012] Preferably, the transmission rod includes a rod body, a slider is fixedly connected to the outside of the rod body, and a buckle is fixedly connected to the end of the rod body facing away from the slider; the rod body is slidably installed in the sleeve body, and the slider is slidably installed in the slide groove. When the sleeve body rotates, the slide groove acts on the slider, which drives the rod body to rotate, causing the rod body to drive the buckle to rotate, thus facilitating the rotation of the transmission rod by the rotating sleeve.

[0013] Preferably, the rotating frame includes a frame body, with a limit block fixedly connected inside the frame body, and a fastener fixedly connected to the upper end of the frame body; the lower part of the frame body is rotatably connected to a bearing, and the fastener is engaged with the fastener block. When the transmission rod drives the fastener to rotate, the fastener drives the frame body to rotate, facilitating the rotating frame to drive the swing plate to revolve.

[0014] Preferably, the swing plate includes a plate body with a notch at its lower end; the upper part of the plate body is rotatably mounted on the upper inner wall of the frame, and the notch is in movable contact with a limiting block. When the frame rotates the plate body, the plate body opens outward; when the rotating frame stops rotating, the fixed seat retracts into the frame body by gravity, facilitating the automatic unfolding and retraction of the swing plate.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] 1. Pour the material into the mixing tank, close the machine cover and the mixing tank, and then connect the transmission rod to the rotating frame. Use the motor to drive the rotating sleeve to rotate, which in turn drives the transmission rod to rotate, which in turn drives the rotating frame to rotate. Use centrifugal force to drive the swing plate to open outward, so that the swing plate can stir the material in the mixing tank. When the rotating frame stops, let the swing plate return to the rotating frame by its own weight, which makes it easy to clean the inside of the mixing tank.

[0017] 2. The baffles are used to increase the eddy current resistance, thereby ensuring the mixing efficiency of the swing plate. The bearings guide the rotation of the rotating frame to facilitate the mixing of the target material.

[0018] 3. The machine cover is guided to swing using a fixed shaft, and the opening range of the machine cover is limited by a limiting plate, making it convenient to open or close the machine cover.

[0019] 4. The spring force of the assist spring acts on the swing arm, which in turn acts on the cover, reducing the force required to open the cover. At the same time, the spring force of the assist spring keeps the cover open, making it easy to operate the cover manually.

[0020] 5. The transmission rod is guided to slide using a slide groove. When the angle between the transmission rod and the rotating frame is misaligned, the transmission rod retracts along the slide groove until it is aligned. Then, the transmission rod is reset and engaged with the rotating frame, which facilitates the connection between the transmission rod and the rotating frame.

[0021] 6. When the sleeve rotates, the sliding groove acts on the slider, which in turn drives the rod to rotate, causing the rod to drive the buckle to rotate, thus facilitating the rotation of the sleeve and the transmission rod.

[0022] 7. When the transmission rod drives the buckle to rotate, the buckle drives the frame to rotate, which facilitates the rotating frame to drive the swing plate to revolve.

[0023] 8. When the frame drives the board to revolve, the board opens outward. When the frame stops rotating, the fixed seat retracts into the frame with the help of gravity, which facilitates the automatic unfolding and retraction of the board. Attached Figure Description
