Description

Technical Field

[0001] This utility model relates to the field of chemical product manufacturing, specifically to a centrifugal device for the production of aryl sulfonamides. Background Technology

[0002] Arylsulfonamides are organic compounds that appear as white, flaky or leaf-like crystals. In the production of arylsulfonamides, intermediate products are placed in a centrifuge to separate the solid and liquid phases, yielding the desired product. Existing centrifuges lack effective stopping devices when shutting down, and there is a lack of equipment around the inner tank to further improve stability during centrifugation.

[0003] Therefore, in order to solve the above-mentioned problems, a centrifugal device for the production of aryl sulfonamides is proposed. Utility Model Content

[0004] This invention addresses the problems mentioned above by designing a centrifugal device for the production of aryl sulfonamides. This device can help stabilize the rotation of the inner tank and can also assist in stopping the inner tank through a deceleration device, thus achieving higher working efficiency.

[0005] To achieve the above objectives, this utility model provides a centrifuge for the production of aryl sulfonamides, comprising: an outer tank, an inner tank, a motor, a support platform, and a reduction gear. The motor is installed at the bottom of the outer tank, and the output shaft of the motor passes through the outer tank and connects to the inner tank. The inner tank is located inside the outer tank and is coaxial with the outer tank. The support platform is fixedly connected to the bottom of the inner wall of the outer tank, and the inner tank is rotatably connected to the support platform. The reduction gear is fixedly connected to the inner wall of the outer tank and is in contact with the outer surface of the inner tank. A plurality of mesh holes are provided on the side wall of the inner tank, and a filter screen is installed inside the inner tank.

[0006] In the above manner, the solid-liquid mixed intermediate product is poured into the filter bag of the inner tank. The filter bag allows the liquid to flow out while leaving the solid. The inner tank is driven by a motor to rotate in the outer tank. The filtered water is discharged through the filter bag, then flows out through the mesh on the inner tank and enters the outer tank for collection, leaving a fixed intermediate product in the inner tank.

[0007] Furthermore, the deceleration device includes a protective shell and an electric telescopic rod. The protective shell is fixedly connected to the inner wall of the outer tank. The electric telescopic rod passes through the side wall of the outer tank and is placed inside the protective shell. One end of the electric telescopic rod away from the outer tank extends out of the protective shell and is fixedly connected to an arc-shaped deceleration plate. The deceleration plate has the same curvature as the outer wall of the inner tank.

[0008] Using the above method, when the filtration is complete and the inner tank needs to be stopped from rotating, the motor is turned off, and the speed reducer is pushed out by the electric telescopic rod to contact the outer wall of the inner tank. Several speed reducers are evenly and intermittently arranged around the inner tank, and the speed reducers assist the inner tank in stopping its rotation through friction.

[0009] Furthermore, the deceleration device also includes: a fixed sleeve, a swing rod, and a pulley. The fixed sleeve is fixedly connected to the electric telescopic rod. The protective shell has clearance grooves on both sides. The swing rod is connected to both sides of the fixed sleeve by torsion springs. The end of the swing rod is rotatably connected to the pulley. A top plate for limiting the swing rod is fixedly connected to the side of the clearance groove away from the inner tank.

[0010] In the above manner, when the electric telescopic rod extends, the swing rods on both sides move forward and leave the limit of the top plate on the swing rods. Under the action of the torsion spring, the swing rods spring away from the electric telescopic rod, so the two pulleys leave the outer wall surface of the inner tank, and the deceleration plate abuts against the outer wall of the inner tank. When the electric telescopic rod retracts, the deceleration plate first leaves the outer wall of the inner tank, and the fixed sleeve drives the swing rod to move backward. The swing rod rotates under the limit of the top plate, so that the rollers contact the outer wall of the inner tank.

[0011] Furthermore, it also includes a top rod, which is fixedly connected to the side of the fixing sleeve.

[0012] Furthermore, it also includes an auxiliary device, which is fixedly connected to the inner wall of the outer tank and slidably connected to the outer wall of the inner tank.

[0013] Furthermore, the auxiliary device includes: a protective shell, a support rod, an arc-shaped plate, and rollers. The support rod is fixedly connected to the inner wall of the outer tank. The protective shell is fitted onto the support rod and fixedly connected to the inner wall of the outer tank. The end of the support rod is fixedly connected to the arc-shaped plate. A plurality of rollers are rotatably connected to the arc-shaped plate. The rollers are slidably connected to the outer wall of the inner tank.

[0014] Furthermore, the inner tank also includes a support ring, which is located on the outer wall of the inner tank, and the deceleration device and the auxiliary device are both connected to the support ring.

[0015] In this way, the rollers, pulleys, and speed reducers all come into contact with the support ring, preventing the mesh on the inner tank from contacting these components.

[0016] In summary, this utility model has the following advantages and beneficial technical effects:

[0017] 1. The centrifugal equipment for the production of aryl sulfonamides of this utility model can play an auxiliary stabilizing role in the rotation of the inner tank, and can also use a deceleration device to assist in stopping the inner tank, thereby achieving higher working efficiency.

[0018] 2. The deceleration device of the centrifuge for the production of aryl sulfonamides of this utility model can switch between two functions: deceleration and auxiliary rotation, which can achieve more diverse auxiliary effects, and the two functions do not interfere with each other;

[0019] 3. The centrifugal equipment for the production of aryl sulfonamides of this utility model can improve the efficiency and stability of solid-liquid separation and accelerate the efficiency of product manufacturing. Attached Figure Description
