Description

Technical Field

[0001] This utility model belongs to the field of reaction vessel technology, specifically relating to an enamel-lined reaction vessel. Background Technology

[0002] In many industries such as chemical, pharmaceutical, and food, enamel-lined reaction vessels have become core equipment for chemical reactions, material mixing, and other operations due to their excellent corrosion resistance, good insulation, and smooth, scale-free inner walls.

[0003] In many chemical reactions within enamel-lined reactors, especially those involving organic synthesis and fermentation, the complexity of the reaction system and the characteristics of the materials often result in the generation of large amounts of foam. This foam significantly impacts the normal progress of the reaction. On one hand, excessive foam occupies reaction space, reducing the effective reaction volume of the reactants and consequently lowering reaction efficiency. For example, in large-scale fermentation production, foam accumulation can cause the actual volume of the fermentation broth to far exceed the safe capacity of the reactor, forcing production to be interrupted to address the foam problem and greatly affecting production progress. On the other hand, the presence of foam also interferes with heat and mass transfer during the reaction process. The poor thermal conductivity of the foam layer hinders the timely dissipation of reaction heat, making precise temperature control difficult. This can trigger side reactions in temperature-sensitive reactions, thereby reducing product purity and recovery rate. Utility Model Content

[0004] The purpose of this invention is to provide an enamel-lined reaction vessel to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an enamel-lined reaction vessel, comprising:

[0006] The base plate has a reaction vessel connected to its top via a support leg. The top of the reaction vessel is sealed with a top cover. A stirring rod for stirring the reactants is rotatably connected to the bottom center of the top cover via a bearing. The reaction vessel is equipped with a defoaming component for defoaming the bubbles generated during the reaction. The defoaming needle is rotated by the rotating rod of the defoaming component so that it contacts and punctures the bubbles when it rotates.

[0007] The nozzles are provided in several groups and are all located inside the reaction tank, and are used to spray defoaming water to eliminate foam.

[0008] Preferably, the defoaming component includes a first bevel gear, and a sealing box is rotatably connected to the surface of the stirring rod via a bearing. The first bevel gear is disposed inside the sealing box and fixedly fitted onto the surface of the stirring rod. Second bevel gears mesh on both sides of the first bevel gear. The rotating rod is provided with two sets, and one end of each set of rotating rods is connected to the two sets of second bevel gears respectively. The other end rotates through the sealing box and is rotatably connected to the reaction vessel via a bearing.

Detailed Implementation

[0023] 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.

[0024] This utility model provides, for example Figure 1-4 The enamel-lined reaction vessel shown includes:

[0025] The base plate 1 has a reaction vessel 2 connected to its top via a support leg. The top of the reaction vessel 2 is sealed with a top cover 3. A stirring rod 4 for stirring the reactants is rotatably connected to the bottom center of the top cover 3 via a bearing. The reaction vessel 2 is equipped with a defoaming component for defoaming the bubbles generated by the reaction. The defoaming needle 6 is rotated by the rotating rod 5 of the defoaming component so that the defoaming needle 6 contacts and punctures the bubbles when it rotates.

[0026] The nozzle 7 is provided in several groups and is located inside the reaction tank 2. It is used to spray out defoaming water / agent to eliminate foam.

[0027] The defoaming component includes a first bevel gear 8. A sealing box 18 is rotatably connected to the surface of the stirring rod 4 via a bearing. The first bevel gear 8 is located inside the sealing box 18 and is fixedly fitted onto the surface of the stirring rod 4. Second bevel gears 9 mesh with both sides of the first bevel gear 8. The rotating rod 5 is provided in two sets, with one end of each set of rotating rods 5 connected to the two sets of second bevel gears 9 respectively, and the other end rotatably passing through the sealing box 18 and rotatably connected to the reaction vessel 2 via a bearing.

[0028] The sealing box 8 can cover the first bevel gear 8 and the two sets of second bevel gears 9, which can effectively prevent materials and defoaming water in the reaction tank 2 from entering the gear transmission structure. It can also prevent materials that may be corrosive from coming into contact with the gears, which would cause the gears to rust and wear, affecting their transmission accuracy and service life. With the protection of the sealing box 18, it can ensure that the first bevel gear 8 and the two sets of second bevel gears 9 are always in good working condition, ensuring the stable operation of the defoaming component and thus stably performing the defoaming function.

[0029] The sealing box 8 is fixed to the top wall inside the reaction vessel 2 by a bracket 19. To achieve shaft rotation while maintaining a seal, the stirring rod 4 and the two sets of rotating rods 5 are equipped with rotary plug seals 20 (also known as shaft seals). When the stirring rod 4 and rotating rods 5 rotate, they ensure close contact between the sealing box 18 and the stirring rod 4 and rotating rods 5, thus forming a seal to prevent reactants from entering the sealing box 18 during stirring. The main material of the rotary plug seal can be corrosion-resistant and non-toxic rubber. Simultaneously, the sealing box 18 also provides a support point for the ends of the two sets of rotating rods 5 near the second bevel gear 9.

[0030] The defoaming needles 6 are provided in several groups and are connected in a ring on the surface of the two groups of rotating rods 5.

[0031] The bottom of the top cover 3 is connected to a spray pipe 10, and several nozzles 7 are evenly distributed on the surface of the spray pipe 10.

[0032] The base plate 1 is provided with a water tank 11 and a water pump 12 is provided on the top of the water tank 11. The water inlet of the water pump 12 is connected to the water tank 11 through a pipe, and the water outlet is connected to the spray pipe 10 through a connecting pipe 13. Under the pressure of the water pump 12, the defoaming water enters the spray pipe 10 through the connecting pipe 13 and is sprayed onto the surface of the bubbles through the nozzle 7.

[0033] The top of the top cover 3 is equipped with a motor 14, and the output shaft of the motor 14 rotates through the top cover 3 and is connected to the stirring rod 4.

[0034] The surface of the stirring rod 4 is connected to a spiral stirring blade 15, which stirs the reactants in the reaction vessel 2 to make the materials mix evenly and promote the chemical reaction.

[0035] The bottom of the reaction tank 2 is provided with a discharge pipe 16. The discharge pipe 16 is not only used to discharge the reaction products, but also to discharge the cleaning liquid and residual substances together when cleaning the reaction tank 2. The surface of the water tank 11 is provided with a water inlet connector 17, which facilitates timely replenishment of defoaming water into the water tank 11.

[0036] Before the reaction, the top cover 3 of the enamel-lined reaction vessel is opened to allow the material to enter the reaction vessel 2 from the top of the reaction vessel 2 for reaction. The motor 14 is installed on the top of the top cover 3. When the motor 14 is started, its output shaft provides rotational power to the stirring rod 4. The stirring rod 4 starts to rotate, driving the spiral stirring blades 15 on the surface to stir the reactants in the reaction vessel 2, so that the material is mixed evenly and promotes the chemical reaction.

[0037] When the stirring rod 4 rotates, the first bevel gear 8, which is fixedly mounted on its surface, rotates accordingly. The first bevel gear 8 is meshed with second bevel gears 9 on both sides. The rotation of the first bevel gear 8 will drive the meshed second bevel gears 9 to rotate. One end of the two sets of rotating rods 5 is connected to the two sets of second bevel gears 9 respectively, and the other end is rotatably connected to the reaction vessel 2 through a bearing. Therefore, when the second bevel gear 9 rotates, it will drive the rotating rod 5 to rotate synchronously. Several sets of defoaming needles 6 are connected in a ring on the surface of the rotating rod 5. During the rotation of the rotating rod 5, the defoaming needles 6 rotate accordingly, contact the bubbles generated by the reaction and moved to the top of the reaction vessel 2 and puncture them, thereby achieving mechanical defoaming.

[0038] A water tank 11 is provided on the surface of the base plate 1. A water pump 12 at the top of the water tank 11 pumps out defoaming water (the defoaming water / agent can be flexibly selected according to the reactants in the reaction tank 2, such as dairy products, beverages, or chocolate, in which case the defoaming water is an organosilicon defoamer, or ordinary water, i.e., tap water or industrial water) from the water tank 11. The outlet of the water pump 12 is connected to the spray pipe 10 through the connecting pipe 13. When it is necessary to spray defoaming water, the water pump 12 is started. Under the pressure of the water pump 12, the defoaming water enters the spray pipe 10 through the connecting pipe 13. The spray pipe 10 is connected to the bottom of the top cover 3. Several nozzles 7 are evenly distributed on the surface of the spray pipe 10. The defoaming water is sprayed out from the nozzles 7, forming a fine water mist in the reaction tank 2. The fine water mist adheres to the liquid film of the foam, increasing the weight of the liquid film of the foam and causing the foam to break, further eliminating the foam generated by the reaction. This works in conjunction with the mechanical defoaming method of the defoaming needle 6 to enhance the defoaming effect.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
