Description

Technical Field

[0001] This utility model relates to the field of resin production technology, and specifically to a reaction vessel for resin production. Background Technology

[0002] A resin production reactor is a key piece of equipment specifically designed for resin production processes. It is a container capable of carrying out physical or chemical reactions under specific conditions. Through structural design and parameter configuration, it achieves the functions of heating, evaporation, cooling, and mixing required by the process.

[0003] During resin production, due to the viscosity of the resin, some resin adheres to the inner wall of the reactor during the discharge process after stirring, resulting in incomplete discharge. This situation has several drawbacks. First, incomplete discharge leads to resin waste and increases production costs. Second, the resin remaining on the inner wall of the reactor will harden over time, which not only increases the difficulty of cleaning but may also lead to incomplete cleaning of the reactor, affecting the quality of subsequent batches of resin products. In addition, residual resin may be mixed into the new batch of products in the next production process, causing a decrease in product purity, affecting the uniformity and molecular weight distribution of the resin, and thus affecting the physical properties of the resin, such as hardness, toughness, and solubility.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0043] like Figure 1-2As shown, a resin production reactor includes a reactor body 1; a fixing frame 2 fixed to the top of the reactor body 1; a motor 3 mounted on the fixing frame 2; a stirring shaft 4 rotatably mounted inside the reactor body 1; a slot 5 formed at the top of the stirring shaft 4; a lifting ring 6 slidably disposed inside the reactor body 1, with the outer circumferential surface of the lifting ring 6 in contact with the inner surface of the reactor body 1; and a spring 7, one end connected to the inner top surface of the reactor body 1 and the other end connected to the lifting ring 6.

[0044] The resin production reactor also includes a drive structure mounted on the output shaft of the motor 3. The drive structure includes: a drive rod 81 fixed to the output shaft of the motor 3; a groove 82 formed at the bottom end of the drive rod 81; a rotating rod 83 slidably disposed within the groove 82, with its bottom end extending to the outside of the groove 82; and a drive block 84 fixed to the bottom end of the rotating rod 83. Initially, the drive block 84 is located within the slot 5. Since both the drive block 84 and the slot 5 have rectangular cross-sections, the drive block 84 can pass through the slot. 5 drives the stirring shaft 4 to rotate. In this case, the motor 3 operates and drives the drive rod 81 to rotate. Since the cross-sections of the groove 82 and the rotating rod 83 are both rectangular, and the outer surface of the rotating rod 83 is in contact with the groove wall of the groove 82, the drive rod 81 can drive the rotating rod 83 to rotate. When the rotating rod 83 rotates, it drives the drive block 84 to rotate, so that the drive block 84 drives the stirring shaft 4 to rotate. The stirring shaft 4 is fixed with stirring blades. When the stirring shaft 4 rotates, the stirring blades on it stir the resin inside the reactor body 1.

[0045] The resin production reactor also includes a lifting structure, which is installed on the reactor body 1. The lifting structure includes: a bearing seat 91, fixed to the reactor body 1; a rotating rod 92, rotatably mounted on the bearing seat 91; a through-hole 93, opened on the rotating rod 92, through which the rotating rod 83 passes; a side plate 94, fixed to the reactor body 1; two bevel gears 95, one of which is fixedly sleeved on the rotating rod 92, and the two bevel gears 95 mesh with each other; a shaft 96, rotatably mounted on the side plate 94, and the other bevel gear 95 is fixedly sleeved on the shaft 96; a winding wheel 97, fixedly sleeved on the shaft 96; and a pull wire 98, one end of which is connected to the winding wheel 97, and the other end of which is connected to the lifting ring 6. The inner bottom of the reactor body 1... Both the top of the part and the top of the reactor body 1 are equipped with pulleys. The pull wire 98 passes around two pulleys. The cross-sections of the groove 82 and the rotating rod 83 are both rectangular, and the outer surface of the rotating rod 83 is in contact with the groove wall of the groove 82. The cross-sections of the drive block 84 and the slot 5 are both rectangular, and the side of the drive block 84 is in contact with the side of the slot 5. When the shaft 96 rotates, it drives the winding wheel to rotate. When the winding wheel rotates, it can wind up the pull wire 98, so that the pull wire 98 pulls the lifting ring 6 downward, thereby causing the lifting ring 6 to move downward inside the reactor body 1. During the downward movement, the lifting ring 6 can scrape off the residual resin adhering to the inner wall of the reactor body 1, thus cleaning the residual resin adhering to the inner wall of the reactor body 1.

[0046] The resin production reactor also includes a control structure located above the reactor body 1. The control structure includes: a movable ring 101, sleeved on the rotating rod 83, with a handle fixed on the movable ring 101; and a fixed ring 102, fixedly sleeved on the rotating rod 83, located above the movable ring 101. After the stirring is completed, the operator discharges the resin inside the reactor body 1. After the discharge is completed, the operator pulls up the handle, causing the handle to move the movable ring 101 upward. When the movable ring 101 moves upward, it can drive the fixed ring 102 upward, which causes the rotating rod 83 to move upward as well.

[0047] The working principle of this utility model:

[0048] In the initial state of use, the driving block 84 of the resin production reactor proposed in this utility model is located in the slot 5. Since the cross-section of the driving block 84 and the slot 5 are both rectangular, the driving block 84 can drive the stirring shaft 4 to rotate through the slot 5. In this case, the motor 3 runs and drives the driving rod 81 to rotate. Since the cross-section of the groove 82 and the rotating rod 83 are both rectangular, and the outer surface of the rotating rod 83 is in contact with the groove wall of the groove 82, the driving rod 81 can drive the rotating rod 83 to rotate. When the rotating rod 83 rotates, it drives the driving block 84 to rotate, so that the driving block 84 drives the stirring shaft 4 to rotate. The stirring shaft 4 is fixed with stirring blades. When the stirring shaft 4 rotates, the stirring blades on it stir the resin inside the reactor body 1. In addition, in the initial state, under the elastic force of the spring 7, the lifting ring 6 is located at the inner top of the reactor body 1.

[0049] After the stirring is completed, the staff discharges the resin inside the reactor body 1. After discharge, the staff pulls up the lever, causing the movable ring 101 to move upward. When the movable ring 101 moves upward, it causes the fixed ring 102 to move upward, which in turn causes the rotating rod 83 to move upward. When the rotating rod 83 moves upward, it causes the driving block 84 to move upward, so that the driving block 84 moves out of the slot 5 and inserts into the through-hole 93. The through-hole 93 has a rectangular cross-section. When the driving block 84 is inserted into the through-hole 93, the side of the driving block 84 fits against the inner surface of the through-hole 93. Therefore, when the driving block 84 rotates, it can drive the rotating rod 92 to rotate. In this case, the staff starts the motor 3, causing the driving block 84 to rotate. When the rotating rod 92 rotates, it drives the shaft 96 to rotate through two meshing bevel gears 95. When the shaft 96 rotates, it drives the winding wheel to rotate. When the winding wheel rotates, it can wind up the pull wire 98, causing the pull wire 98 to pull the lifting ring 6 downward. This causes the lifting ring 6 to move downward inside the reactor body 1. During the downward movement, the lifting ring 6 can scrape off the residual resin adhering to the inner wall of the reactor body 1, thus cleaning the residual resin adhering to the inner wall of the reactor body 1. This allows the resin to be completely discharged from the inside of the reactor body 1, preventing resin residue from remaining on the inner wall of the reactor body 1. In summary, this device can use the motor 3 to achieve the dual functions of stirring and driving the lifting ring 6 to move downward.
