Abstract
Description
Technical Field
[0001] This utility model relates to the field of isoprene rubber production technology, specifically to a coagulation device for isoprene rubber production. Background Technology
[0002] Isoprene rubber is a high-performance rubber used in tire production. In the traditional isoprene rubber production process, a mixture of rubber solution and steam is sprayed into water in a tank to condense and form coagulated isoprene rubber. However, in the existing technology, the feeding port of the tank is fixed, which means that the position where the rubber solution falls into the tank is fixed. This results in a high temperature of the solution near the rubber solution spraying part and a low temperature in other parts of the tank. The high temperature of the solution will affect the coagulation rate of isoprene rubber. There are now patent documents that have improved this.
[0003] For example, Chinese patent CN215087159U describes a coagulation device for isoprene rubber production. It includes a tank body with a feeding mechanism inside. The feeding mechanism includes a bearing mounted on the top of the tank body, with a feeding cylinder fitted inside the bearing's inner ring. The stirring mechanism includes a lifting frame fixedly mounted on the bottom of the feeding cylinder. A reversible motor is mounted on the top of the lifting frame. By setting up the feeding cylinder and discharge nozzle, when the reduction motor drives the feeding cylinder to rotate, the spray position of the rubber solution can be changed, avoiding inconsistent solution temperature caused by a fixed spray position. Furthermore, by setting up a rotating plate, large rubber particles are avoided. The combination of the reversible motor, threaded rod, and stirring blades ensures more uniform stirring compared to existing technologies, eliminating dead zones and guaranteeing consistent solution temperature.
[0004] Although the aforementioned patent uses a geared motor to drive the feed cylinder to rotate, which can change the spray position of the adhesive and avoid inconsistent solution temperature caused by a fixed spray position, the adhesive is only sprayed around the outer perimeter of the feed cylinder by the geared motor. This limits the spray range of the adhesive and still results in high temperature at the spray position, affecting the coagulation rate of isoprene rubber. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a coagulation device for isoprene rubber production, which solves the problem that the rubber liquid is only sprayed around the outer perimeter of the feed cylinder, resulting in a limited spraying range and still causing high temperatures at the spraying point, thus affecting the coagulation rate of isoprene rubber.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a coagulation device for isoprene rubber production, comprising a coagulation tank body. A feeding pipe is rotatably connected to the top of the coagulation tank body via an opening. Discharge pipes are connected to both sides of the outer surface of the feeding pipe and inside the coagulation tank body. A sliding pipe is slidably connected inside the discharge pipe. A driving mechanism is provided on one side of the top of the coagulation tank body. A fixing plate is fixedly connected above the outer surface of the discharge pipe. A connecting plate is fixedly connected above the outer surface of the sliding pipe. A spring is fixedly connected between one side of the fixing plate and one side of the connecting plate. A cylindrical plate is fixedly connected to the top of the connecting plate. Several arc-shaped plates adapted to the cylindrical plates are fixedly connected to the inner surface of the coagulation tank body and above the connecting plate.
[0007] Preferably, the driving mechanism includes a motor, which is fixedly connected to the top of the condensing tank body via a fixing frame. The output shaft of the motor is fixedly connected to a rotating rod via a coupling. One end of the rotating rod is rotatably connected to the top of the condensing tank body via a bearing. A first gear and a second gear are fixedly connected to the outer surface of the rotating rod and the outer surface of the feeding pipe, respectively.
[0008] Preferably, a stirring rod is fixedly connected to the bottom end of the feeding pipe, and a plurality of stirring sleeves are fixedly connected to the outer surface of the stirring rod.
[0009] Preferably, agitator plates are fixedly connected to both sides of the outer surface of the agitator sleeve.
[0010] Preferably, the bottom of the condensation tank body is connected to a discharge pipe.
[0011] Preferably, a valve is provided on the outer surface of the discharge pipe.
[0012] Beneficial effects
[0013] This invention provides a coagulation device for isoprene rubber production. Compared with existing technologies, it has the following advantages:
[0014] (1) The present invention uses a motor to drive the feeding pipe to rotate, which in turn drives the discharge pipe and the sliding pipe to rotate. The discharge pipe and the sliding pipe spray out the adhesive. At the same time, the cylindrical plate on the connecting plate squeezes the arc plate, causing the cylindrical plate to retract the sliding pipe into the sliding pipe through the connecting plate. Then, through the action of the spring, the connecting plate drives the sliding pipe to extend out from the discharge pipe. The discharge pipe and the sliding pipe extend and retract in turn, so that the position of the adhesive sprayed by the sliding pipe is sometimes far and sometimes near, which can effectively spray the adhesive at different positions and improve the coagulation rate of isoprene rubber.
[0015] (2) The present invention drives the stirring rod to rotate through the feeding pipe. The stirring rod drives multiple stirring plates to rotate through the stirring sleeve. The multiple stirring plates will stir the solution in the body of the coagulation tank, making the temperature of the solution in the body of the coagulation tank more uniform and ensuring the consistency of the solution temperature.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] Please see Figure 1-4 This utility model provides a technical solution: a coagulation device for isoprene rubber production, including a coagulation tank body 1. The top of the coagulation tank body 1 is rotatably connected to a feeding pipe 2 through an opening. Both sides of the outer surface of the feeding pipe 2 and inside the coagulation tank body 1 are connected to a discharge pipe 3. A sliding pipe 4 is slidably connected inside the discharge pipe 3. A driving mechanism 5 is provided on one side of the top of the coagulation tank body 1. A fixing plate 6 is fixedly connected above the outer surface of the discharge pipe 3. A connecting plate 7 is fixedly connected above the outer surface of the sliding pipe 4. A spring 8 is fixedly connected between one side of the fixing plate 6 and one side of the connecting plate 7. A cylindrical plate 9 is fixedly connected to the top of the connecting plate 7. Several arc-shaped plates 10 adapted to the cylindrical plates 9 are fixedly connected to the inner surface of the coagulation tank body 1 and above the connecting plate 7.
[0023] It should be noted that the solution in the condensation tank body 1 is added below the arc-shaped plate 10.
[0024] Furthermore, in order to facilitate the rotation of the feeding pipe 2, the drive mechanism 5 includes a motor 51, which is a servo motor and is electrically connected to an external power source. It is controlled by a control switch. The motor 51 is fixedly connected to the top of the coagulation tank body 1 by a fixing bracket. The output shaft of the motor 51 is fixedly connected to a rotating rod 52 by a coupling. One end of the rotating rod 52 is rotatably connected to the top of the coagulation tank body 1 by a bearing. The outer surface of the rotating rod 52 and the outer surface of the feeding pipe 2 are respectively fixedly connected to a first gear 53 and a second gear 54.
[0025] Furthermore, in order to agitate the solution inside the coagulation tank body 1, a stirring rod 11 is fixedly connected to the bottom end of the feeding pipe 2, and several stirring sleeves 12 are fixedly connected to the outer surface of the stirring rod 11. Stirring plates 13 are fixedly connected to both sides of the outer surface of the stirring sleeves 12. A discharge pipe 14 is connected to the bottom of the coagulation tank body 1, and a valve 15 is provided on the outer surface of the discharge pipe 14.
[0026] In use, the adhesive is added to the coagulation tank body 1 through the feeding pipe 2. The control motor 51 drives the rotating rod 52 to rotate. The rotating rod 52 drives the feeding pipe 2 to rotate through the first gear 53 and the second gear 54. The feeding pipe 2 will drive the discharge pipe 3 and the sliding pipe 4 to rotate, and the adhesive in the feeding pipe 2 will be sprayed out through the discharge pipe 3 and the sliding pipe 4 to coagulate rubber. At the same time, the rotation of the discharge pipe 3 and the sliding pipe 4 will drive the cylindrical plate 9 to rotate. The cylindrical plate 9 contacts and squeezes the arc plate 10, and the discharge pipe 3 will retract into the sliding pipe 4. Then, through the action of the spring 8, the spring 8 pushes the sliding pipe 4 to extend out through the connecting plate 7, so that the discharge pipe 3 and the sliding pipe 4 extend and retract in turn. The adhesive sprayed from the discharge pipe 3 is sometimes far and sometimes near, so that the position of the adhesive sprayed from the discharge pipe 3 is different.
[0027] As the feeding pipe 2 rotates, it drives the stirring rod 11 to rotate. The stirring rod 11 drives multiple stirring plates 13 to rotate through the stirring sleeve 12. The stirring plates 13 stir the solution in the coagulation tank body 1, making the temperature of the solution in the coagulation tank body 1 more uniform.
