Abstract
Description
Technical Field
[0001] This utility model relates to the field of polymerization inhibitor preparation technology, specifically a high-density polymerization inhibitor temperature-controlled stirred reactor. Background Technology
[0002] As a key auxiliary agent in the chemical industry, polymerization inhibitors are mainly used to inhibit polymerization reactions and extend the product storage period. In the process of preparing polymerization inhibitors, a reaction vessel is required.
[0003] Currently, because the reactor needs to ensure good sealing in the process of preparing the polymerization inhibitor, traditional seals or packing seals are prone to gaps due to wear and thermal expansion and contraction during long-term operation, which can cause air to seep into the reaction system, leading to oxidation failure of the polymerization inhibitor or uncontrolled polymerization reaction, leakage of toxic and harmful gases, threatening the health of operators and polluting the environment. In view of this, a high-density variable temperature stirred reactor for polymerization inhibitor is proposed. Utility Model Content
[0004] The main objective of this invention is to provide a high-density polymerization inhibitor temperature-controlled stirred reactor that can solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention proposes a high-density polymerization inhibitor temperature-controlled stirring reactor, comprising a reactor body, a heating chamber fixedly connected to the outer wall of the reactor body, a cover provided on the top of the reactor body, the reactor body and the cover being sealed by a sealing compensation assembly, an opening and closing mechanism provided on the reactor body, a temperature detector fixedly installed on the inner surface of the cover, and a mixing mechanism provided in the reactor body. The sealing compensation assembly includes:
[0006] An annular sleeve, which is fixedly connected to the outer wall of the vessel body;
[0007] A sealing ring, wherein the sealing ring is embedded in the annular sleeve;
[0008] The pressure ring is fixedly connected to the outer wall of the cover. When the cover and the top of the vessel are tightly fitted together, the pressure ring can squeeze the sealing gas ring, so that the deformation of the sealing gas ring is tightly fitted with the notch of the pressure ring, thereby improving the sealing effect between the cover and the vessel. Furthermore, when the sealing gas ring wears down after long-term use, the sealing gas ring has a certain elasticity, which can compensate for the seal and ensure the sealing effect.
[0009] Preferably, the opening and closing mechanism includes a fixed plate, a connecting member is hinged to the top of a fixed frame and fixedly connected to the upper side of the fixed plate, a connecting block is hinged to the end of the connecting member away from the fixed frame, the connecting block is fixedly connected to the cover, and an electric cylinder is provided above the fixed plate. The use of the opening and closing mechanism facilitates the opening of the cover, facilitates subsequent cleaning of the inside of the vessel, and also facilitates the replacement of the sealing ring.
[0010] Preferably, the electric cylinder is hinged to the fixed frame via a rod body one, and a fixed block is fixedly connected to the output end of the electric cylinder. The fixed block is hinged to the connecting member via a rod body two.
[0011] Preferably, the mixing mechanism includes a rotating shaft, a stirring blade is fixedly connected to the bottom of the rotating shaft, the rotating shaft passes through the rotating assembly, a vertical rod is provided below the rotating assembly, and multiple sets of stirring rods are equidistantly arrayed on the vertical rod.
[0012] Preferably, a motor is fixedly connected to the top of the cover, and the output shaft of the motor is fixedly connected to the rotating shaft.
[0013] Preferably, the rotating assembly includes a gear ring, a driven gear, a positioning shaft, and a driving gear. The gear ring meshes with the driven gear, and the driven gear meshes with the driving gear. The driving gear is penetrated by the rotating shaft and fixedly connected to the rotating shaft. The positioning shaft is fixed to the driven gear. The rotating shaft is driven to rotate by the output shaft of the motor, which in turn drives the stirring blade and the driving gear to rotate. This causes the gear ring to drive the vertical rod and the stirring rod to rotate. The rotation directions of the gear ring and the rotating shaft are opposite, which improves the mixing effect of the raw materials and makes the internal heating of the raw materials more uniform.
[0014] Preferably, the toothed ring is rotatably connected to the lower side of the cover, and the top of the positioning shaft is rotatably connected to the lower side of the cover.
[0015] This invention provides a high-density polymerization inhibitor temperature-controlled stirred reactor. It has the following beneficial effects:
[0016] (1) The high-density polymerization inhibitor temperature-controlled stirred reactor uses a sealing compensation component. When the lid is closed, the pressure ring squeezes the sealing gas ring, causing it to deform and fit tightly against the pressure ring recess. This effectively blocks the flow of external air to the reaction system, preventing the polymerization inhibitor from oxidizing and failing or the polymerization reaction from going out of control. At the same time, it avoids the leakage of toxic and harmful gases, ensuring the safety of operators and the environment. In addition, the sealing gas ring has an elastic compensation function. Even after long-term use and wear, it can still maintain a good sealing effect by its own elasticity, reducing reaction abnormalities and safety hazards caused by sealing failure, and ensuring the long-term stable operation of the reactor.
[0017] (2) The high-density polymerization inhibitor temperature-controlled stirring reactor can easily open and close the lid through the use of the opening and closing mechanism, which makes it convenient for operators to clean the inside of the reactor and clean up residual materials in time; at the same time, it is convenient to inspect and replace the sealing ring, reduce the difficulty of equipment maintenance, shorten maintenance time, and improve equipment utilization efficiency.
[0018] (3) The high-density polymerization inhibitor variable temperature stirring reactor uses a mixing mechanism. During the rotation of the rotating shaft driven by the motor, not only does the stirring blade stir the raw material, but also the vertical rod and stirring rod rotate in the opposite direction to the rotating shaft through the transmission of the driving gear, driven gear and gear ring, forming a bidirectional stirring effect, which greatly improves the mixing efficiency of the raw material, promotes uniform heating inside the raw material, and ensures that the polymerization inhibitor preparation reaction is fully carried out.

[0030] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0031] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see Figures 1-5 This utility model proposes a high-density polymerization inhibitor temperature-variable stirring reactor, including a reactor body 1, a heating chamber 2 fixedly connected to the outer wall of the reactor body 1, an inlet and an outlet of water opened on the heating chamber 2, the reaction temperature of the reactor body 1 is adjusted by the temperature of the water flow, a cover 3 is provided on the top of the reactor body 1, the reactor body 1 and the cover 3 are sealed by a sealing compensation component 4, an opening and closing mechanism 5 is provided on the reactor body 1, a temperature detector 6 is fixedly installed on the inner surface of the cover 3, and a mixing mechanism 7 is provided in the reactor body 1.
[0033] In an embodiment of this utility model, in order to enable the lid 3 to open and close, the opening and closing mechanism 5 specifically includes a fixing plate 51. The upper side of the fixing plate 51 is fixedly connected to a fixing frame 52, and a connecting member 53 is hinged to the top of the fixing frame 52. A connecting block 54 is hinged to the end of the connecting member 53 away from the fixing frame 52. The connecting block 54 is fixedly connected to the lid 3. An electric cylinder 56 is provided above the fixing plate 51. The electric cylinder 56 is hinged to the fixing frame 52 through a rod 55. A fixing block 58 is fixedly connected to the output end of the electric cylinder 56. The fixing block 58 is hinged to the connecting member 53 through a rod 57. When the output end of the electric cylinder 56 retracts, it drives the connecting block 54 to move, thereby driving the connecting member 53 to rotate around its hinge axis with the fixing frame 52, so that the lid 3 is separated from the vessel body 1. Conversely, it can make the lid 3 and the vessel body 1 fit tightly together.
[0034] Furthermore, the sealing compensation component 4 includes an annular sleeve 41, a sealing ring 42, and a pressure ring 43. The annular sleeve 41 is fixedly connected to the outer wall of the reactor body 1, the sealing ring 42 is embedded in the annular sleeve 41, and the pressure ring 43 is fixedly connected to the outer wall of the cover body 3. When the cover body 3 is closed, the pressure ring 43 squeezes the sealing ring 42, causing it to deform and tightly fit the notch of the pressure ring 43, effectively blocking the flow of external air to the reaction system, preventing the polymerization inhibitor from oxidizing and failing or the polymerization reaction from going out of control, while avoiding the leakage of toxic and harmful gases, ensuring the safety of operators and the environment. At the same time, the sealing ring 42 has an elastic compensation function. Even after long-term use and wear, it can still maintain a good sealing effect by relying on its own elasticity, reducing reaction abnormalities and safety hazards caused by sealing failure, and ensuring the long-term stable operation of the reactor.
[0035] Furthermore, the mixing mechanism 7 includes a rotating shaft 71. A motor is fixedly connected to the top of the cover 3, and the output shaft of the motor is fixedly connected to the rotating shaft 71. A stirring blade 72 is fixedly connected to the bottom of the rotating shaft 71. The rotating shaft 71 passes through the rotating assembly 73. A vertical rod 74 is provided below the rotating assembly 73. Multiple sets of stirring rods 75 are equidistantly arranged on the vertical rod 74. The rotating assembly 73 includes a gear ring 731, a driven gear 732, a positioning shaft 733, and a driving gear 734. The gear ring 731 meshes with the driven gear 732, and the driven gear 732 meshes with the driving gear 734. The driving gear 734 is driven by the rotating shaft 71. The gear ring 731 is rotatably connected to the lower side of the cover 3, and the top of the positioning shaft 733 is rotatably connected to the lower side of the cover 3. The output shaft of the motor drives the rotating shaft 71 to rotate, which in turn drives the stirring blade and the driving gear 734 to rotate. Under the transmission action of the driven gear 732, the gear ring 731 drives the vertical rod 74 and the stirring rod 75 to rotate. The rotation direction of the gear ring 731 is opposite to that of the rotating shaft 71, which improves the mixing effect of the raw materials, makes the internal heating of the raw materials more uniform, and ensures that the reaction for preparing the polymerization inhibitor is fully carried out.
[0036] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.
[0037] In use, the raw materials are first added to the vessel body 1, and then the electric cylinder 56 is started. The output end of the electric cylinder 56 extends, driving the connecting block 54 to move, which in turn drives the connecting piece 53 to rotate around its hinge axis with the fixed frame 52, so that the cover 3 and the vessel body 1 are tightly fitted. During this process, the pressure ring 43 squeezes the sealing gas ring 42, causing it to deform and fit tightly against the notch of the pressure ring 43. Then the motor is started, and the output shaft of the motor drives the rotating shaft 71 to rotate, which can drive the stirring blade and the driving gear 734 to rotate. Under the transmission action of the driven gear 732, the toothed ring 731 drives the vertical rod 74 and the stirring rod 75 to rotate. The rotation direction of the toothed ring 731 and the rotating shaft 71 is opposite, so that the raw materials are fully mixed and the internal heating of the raw materials is more uniform. Then the water flows in through the inlet and out through the outlet. The reaction temperature of the vessel body 1 is controlled by the temperature of the water flow, and the temperature is monitored by the temperature detector 6.
