DETAILED DESCRIPTION

[0033] Example 1:

[0034] like Figure 1 、 2 As shown in Figure 3, a water outlet mechanism for a rubber antioxidant reactor comprises a tank body 1, a motor 4 on the top of the tank body 1 and a stirring shaft 101 inside the tank body 1. The tank body 1 represents the tank structure of an existing rubber antioxidant reactor. The motor 4 is a motor commonly used in existing reactors. The motor 4 is used to drive the stirring shaft 101. The stirring shaft 101 is the stirring shaft of the reactor and the existing stirring fan blades connected thereto. A water outlet pipe 2 is provided on the outside of the tank body 1. The water outlet pipe 2 is externally connected to a storage tank. The water outlet pipe 2 has its own control valve. A water flow groove 5 is provided in a threaded shape along the inner wall of the tank body 1. The bottom end of the water flow groove 5 is connected to the water outlet pipe 2. When in use, water vapor attached to the inner wall of the tank body 1 is liquefied and gathered into water droplets. After that, it will flow down along the inner wall of the tank body 1 under the action of gravity, and then flow into the water outlet pipe 2 along the water flow groove 5 and be discharged along the water outlet pipe 2. The water outlet pipe 2 can also be used for gas discharge during distillation.

[0035] A plurality of wiper rods 6 are provided along the top of the inner wall of the tank body 1. The wiper rods 6 are closely attached to the inner wall of the tank body 1. The wiper rods 6 are transmission-connected to the stirring shaft 101. When the motor 4 is started and drives the stirring shaft 101 to rotate, the wiper rods 6 can be driven to rotate synchronously. The water vapor attached to the top of the inner wall of the tank body 1 will be affected by the wiper rods 6, and then the water vapor will be scraped off by the wiper rods 6, and then flow along the wiper rods 6 to the water flow trough 5, and finally discharged through the outlet pipe 2.

[0036] In a preferred solution, the bottom end of the water trough 5 is sealed to prevent water from flowing back to the bottom end of the tank body, so as to ensure the quality of the product.

[0037] In a further embodiment, Figure 6 As shown, the wiper rod 6 includes a rod body 601, and a guide groove 602 is provided in the rod body 601. The guide groove 602 is close to the inner wall of the tank body 1. A scraper 603 is provided on the side of the rod body 601 close to the inner wall of the tank body 1. The scraper 603 is close to the inner wall of the tank body 1. During the rotation of the wiper rod 6, the water vapor attached to the top of the inner wall of the tank body 1 will be scraped by the scraper 603, and then gathered into water droplets and flow into the guide groove 602, and finally flow down along the guide groove 602, so as to prevent the water vapor and water droplets attached to the top of the inner wall of the tank body 1 from falling directly back into the product, especially from falling back after the reaction is completed, thereby ensuring the quality of the product.

[0038] In the preferred embodiment, the water trough 5 is located directly below the bottom end of the guide trough 602. The water dropped by the scraper 603 can fall into the guide trough 602. The water flowing down the guide trough 602 can fall into the water trough 5 and finally be discharged through the outlet pipe 2.

[0039] Example 2:

[0040] like Figure 2 、 3 As shown in , 4 and 5, a rotating sleeve 402 is provided at the top of the stirring shaft 101, the wiper rod 6 is connected to the rotating sleeve 402, the rotating sleeve 402 is connected to a driven gear 403, and the output shaft of the motor 4 is provided with a driving gear 401, the driving gear 401 and the driven gear 403 are engaged, and the driving gear 401 and the driven gear 403 are located inside the fixed shell 3.

[0041] When in use, the starting motor 4 can drive the driving gear 401 to rotate, thereby driving the driving gear 401 to rotate, which can drive the rotating sleeve 402 and the wiper rod 6 to rotate to complete wiper, and drive the stirring shaft 101 to rotate through the rotating sleeve 402 to complete stirring.

[0042] In a further embodiment, in order to complete the wiper operation even when stirring is not performed, an adjustment mechanism 7 is provided between the rotating sleeve 402 and the stirring shaft 101 for controlling the transmission between the rotating sleeve 402 and the stirring shaft 101 .

[0043] In the preferred embodiment, the adjustment mechanism 7 includes a cylinder 701, which is connected to the top of the fixed shell 3. The cylinder 701 is an existing air cylinder and can also be replaced by an oil cylinder. It is controlled by existing technology. A fixed shaft 706 is provided at the output end of the cylinder 701. The end of the fixed shaft 706 away from the cylinder 701 is rotatably connected to a slider 707. The slider 707 and the fixed shaft 706 can rotate relative to each other. Therefore, the rotation of the stirring shaft 101, the rotating sleeve 402 and the slider 707 will not affect the cylinder 701. The slider 707 is only slidably connected to the rotating sleeve 402. The end of the slider 707 away from the cylinder 701 is provided with a plug-in block 708.

[0044] A connecting shaft 702 is provided at the top of the stirring shaft 101, and a limiting shaft 703 is provided at the top of the connecting shaft 702. The connecting shaft 702 and the limiting shaft 703 are rotatably connected to the inside of the rotating sleeve 402. A plug hole 705 is provided at the top of the limiting shaft 703, and the plug hole 705 is adapted to the plug block 708.

[0045] During use, if stirring and scraping are required, the cylinder 701 is started to drive the fixed shaft 706, the slider 707 and the plug-in block 708 to move downward until the plug-in block 708 enters the plug-in hole 705. Then, in the process of the motor 4 driving the rotating sleeve 402 to rotate, the slider 707, the plug-in block 708 and the limit shaft 703 will be driven to rotate in turn, thereby driving the connecting shaft 702 and the stirring shaft 101 to rotate in turn, so as to complete stirring while scraping. When stirring is not required and only scraping is needed, the cylinder 701 is retracted to drive the plug-in block 708 away from the plug-in hole 705. At this time, the rotation of the rotating sleeve 402 cannot drive the limit shaft 703 to rotate, so that only scraping can be completed without participating in stirring. The operation is simple and can adapt to different usage requirements.

[0046] In a preferred embodiment, a sliding hole 704 adapted to the slider 707 is provided in the rotating sleeve 402, and the slider 707 is slidably disposed inside the sliding hole 704;

[0047] The cross-sections of the slider 707, the sliding hole 704, the plug hole 705 and the plug block 708 are all polygonal, preferably quadrilateral or hexagonal, so as to ensure the transmission between the slider 707 and the rotating sleeve 402, and also ensure the transmission between the plug block 708 and the limit shaft 703.

[0048] In the preferred solution, bearings are provided between the connecting shaft 702 and the limiting shaft 703 and the rotating sleeve 402 to ensure the stability of the relative rotation of the rotating sleeve 402 and the connecting shaft 702 and the limiting shaft 703, and bearings are provided between the fixed shaft 706 and the slider 707.

[0049] The "water vapor" referred to in this application does not only refer to steam formed by water, but also refers to other steam impurities produced by the reaction of rubber antioxidants; the "rubber antioxidant" in this application cannot be interpreted as a limitation of this application, but merely represents that the structure of this application is mainly used for rubber antioxidant processing, and is an invention completed in the process of rubber antioxidant processing.
