Description

Technical Field

[0001] The invention relates to the technical field of chemical equipment, and in particular to a mildew and antibacterial agent reaction kettle. Background Art

[0002] Stirred reactor is a kind of equipment widely used in chemical, pharmaceutical, food and other industries for mixing, dissolving, reacting and other processes. Its working principle is to stir the raw materials in the reactor through the agitator to make them evenly mixed. The production of antifungal and antibacterial agents is one of the application fields of stirred reactor.

[0003] In an existing stirred reactor, raw materials are usually added into the reactor through a feed port on the top, and then the agitator is rotated to stir the raw materials. Since the raw materials added from the feed port, especially powdered raw materials, often accumulate and float on the liquid surface and are not easy to disperse, it takes a long time to stir them evenly, which not only reduces the production efficiency, but also may affect the reaction effect, thereby reducing the product quality. Summary of the invention

[0004] In view of this, the present invention provides an antifungal and antibacterial agent reaction kettle, which can deliver the raw materials required for the reaction into the interior of the solvent, shortens the time consumed for uniform stirring, and achieves better stirring effect.

[0005] To achieve the above objectives, the present invention provides the following technical solutions.

[0006] The mildew and antibacterial agent reaction kettle comprises a kettle body and a stirring device. The solvent and raw materials required for the reaction are added into the kettle body respectively. The stirring device stirs them evenly to form a mixed liquid. The stirring device comprises a stirrer, a stirring drive assembly and a blowing assembly. The stirrer extends into the kettle body and can rotate. A feeding channel for conveying raw materials is provided inside the stirrer. The feeding channel is provided with discharge ports at different depth positions in the kettle body. The stirring drive assembly is used to drive the stirrer to rotate. The blowing assembly comprises a blowing pipe and a blowing air source. The blowing pipe is provided with a feeding port and connected to the feeding channel. The blowing air source is connected to the blowing pipe. After the raw materials are added to the blowing pipe from the feeding port, the blowing air source blows the raw materials into the feeding channel, and blows the raw materials out from multiple discharge ports at different depth positions in the kettle body, so that the raw materials can be directly conveyed into different depth positions inside the solvent.

[0007] By setting up a feeding channel inside the agitator, and providing discharge ports at different depths in the kettle body, the raw materials can be directly blown into different depths inside the solvent through the feeding channel, avoiding the accumulation of raw materials floating on the solvent liquid surface. The time spent on uniform stirring is shorter, the stirring effect is better, the reaction effect is better, and the product quality is therefore better.

[0008] Furthermore, a one-way feeding valve is provided at the discharge port, which includes a fixed valve seat, a sliding valve core and a first spring. The fixed valve seat is fixedly provided at the discharge port, the sliding valve core is slidably connected to the fixed valve seat, and the first spring is respectively connected to the sliding valve core and the fixed valve seat to provide the sliding valve core with the elastic force required to block the discharge port. When the blowing air source blows air to the feeding channel to feed the material, the sliding valve core moves outward under the push of the air flow to open the discharge port to form the discharge channel, and the raw material can be blown out from the discharge channel. When the blowing air source stops blowing air to the feeding channel, the sliding valve core moves inward under the action of the first spring to reset and block the discharge port, so as to prevent the mixed liquid from flowing back from the discharge port into the feeding channel.

[0009] Furthermore, the one-way feeding valve also includes a driving turbine and a rotating scraper. The driving turbine includes a turbine shaft and a turbine wheel body. The turbine shaft is rotationally connected to the sliding valve core. The turbine wheel body is provided with a plurality of driving blades so that the airflow can drive the driving turbine to rotate. The rotating scraper is movably connected to the driving turbine. When the one-way feeding valve opens the discharge port, the airflow flows through the driving blades to drive the driving turbine to rotate. The rotating scraper extends to the discharge channel under the action of centrifugation to clean the raw materials remaining in the discharge channel.

[0010] Furthermore, a turbine cylinder seat is also provided in the fixed valve seat, a driving air cavity is provided in the turbine cylinder seat, a scraper air channel is provided in the turbine wheel body, a rotating scraper is slidably connected in the scraper air channel so as to be able to extend and retract the turbine wheel body, the turbine wheel shaft is sleeved with the turbine cylinder seat and extends into the driving air cavity, a connecting air channel is also provided in the turbine wheel shaft, the connecting air channel is connected to the scraper air channel and the driving air cavity respectively, when the sliding valve core is pushed outward by the air flow, the driving turbine rotates and moves outward with the sliding valve core, the turbine wheel shaft moves outward and compresses the air in the driving air cavity to generate air pressure, the air pressure acts on the rotating scraper via the connecting air channel and the scraper air channel, so that the rotating scraper is extended to the discharge channel under the joint drive of centrifugal action and the air pressure. When the sliding valve core moves inward and resets under the action of the first spring, the driving turbine moves inward with the sliding valve core, the turbine wheel shaft moves inward and expands the driving air cavity to generate negative pressure, the negative pressure drives the rotating scraper to retract the turbine wheel body via the connecting air channel and the scraper air channel.

[0011] Further, the connecting airway includes a driving and extending airway and a driving and contracting airway, and the driving and contracting airway and the driving and contracting airway are both connected to the scraper airway and the driving air cavity. The driving and contracting airway is provided with a one-way vent valve, and the conducting direction of the one-way vent valve is from the driving and contracting airway to the driving air cavity. The driving and rotating turbine is also provided with an airway switch assembly, which includes a switch valve core and a second spring. The switch valve core can block the driving and extending airway to close the driving and extending airway, and can slide to conduct the driving and extending airway. The second spring connects the switch valve core to push the switch valve core to reset and close the driving and extending airway. When the driving and rotating turbine reaches a preset speed under the drive of the airflow, the switch valve core overcomes the elastic force of the second spring under the centrifugal action and moves and no longer blocks the driving and extending airway to conduct the driving and extending airway. The air pressure generated by the driving air cavity pushes the rotating scraper to extend through the driving and extending airway; when the speed of the driving and rotating turbine is lower than the preset speed, the switch valve core resets under the action of the second spring to close the driving and extending airway, and the negative pressure generated by the driving air cavity drives the rotating scraper to retract through the driving and contracting airway.

[0012] Furthermore, the stirring drive assembly includes a driving motor, a driving shaft and a magnetic coupling. The driving shaft is fixedly connected to the driving motor to be driven to rotate by the driving motor. The magnetic coupling is respectively connected to the driving shaft and the agitator.

[0013] Furthermore, the agitator is provided with a plurality of blades at different depths in the kettle body, and the discharge port is arranged at the end of each blade. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention is described in detail below in conjunction with specific embodiments.

[0031] like Figure 1-Figure 3 As shown, the mildew and antibacterial agent reaction kettle of this embodiment includes a kettle body 5 and a stirring device. The solvent and raw materials required for the reaction are added into the kettle body 5 respectively, and the stirring device stirs them evenly to form a mixed liquid. The stirring device includes a stirrer 1, a stirring drive component 4 and a blowing component. The stirrer 1 extends into the kettle body 5 and can rotate. It is provided with a plurality of blades 12 at different depths in the kettle body 5. A feeding channel 11 for conveying raw materials is provided inside the stirrer 1. A discharge port (not shown in the figure) is provided at the end of the feeding channel 11 (that is, the end of the blade 12).

[0032] Since the agitator 1 of this embodiment is provided with a feeding channel 11, which needs to be connected to the blowing pipe 3 for feeding, the agitator 1 itself needs to rotate. If a traditional transmission method is used, it will be difficult to achieve the connection between the feeding channel 11 and the blowing pipe 3. Figure 3 and Figure 4As shown, the stirring drive assembly 4 of this embodiment includes a driving motor 41, a driving shaft 42 and a magnetic coupling. The driving shaft 42 is fixedly connected to the driving motor 41 so as to be driven to rotate by the driving motor 41. The magnetic coupling includes an upper joint 43, a lower joint 44 and a connecting seat 45. The upper joint 43 is fixedly connected to the driving shaft 42, and the lower joint 44 is fixedly connected to the stirrer 1. The connecting seat 45 connects the upper joint 43 and the lower joint 44 through a series of bearings, thereby realizing transmission through the magnetic coupling. The stirrer 1 and the driving shaft 42 do not need to be fixed in contact, so as to facilitate the connection between the blowing pipe 3 and the feeding channel 11.

[0033] like Figure 3 As shown, the blowing assembly of this embodiment includes a blowing pipe 3 and a blowing gas source (not shown in the figure), the blowing pipe 3 is provided with a feed port 31 and connected to the feeding channel 11, and the blowing gas source is connected to the blowing pipe 3. After the raw material is added to the blowing pipe 3 from the feed port 31, the blowing gas source blows the raw material into the feeding channel 11, and blows the raw material out from multiple discharge ports at different depths in the kettle body 5, so that the raw material is directly transported into different depths inside the solvent. Different gases are selected to blow the raw materials according to the products produced in the reactor to ensure that the blown gas will not trigger additional reactions. Air can be directly used to blow the raw materials, or inert gas that will not participate in the reaction process. An opening can be set at the top of the reactor for gas outlet. If an inert gas is used, the inert gas can also be recovered from the opening for recycling. The gas blown into the solvent will produce bubbles, which will float up during the stirring process and eventually escape from the solvent, thereby eliminating the bubbles.

[0034] By arranging a feeding channel 11 inside the agitator 1, and providing discharge ports at different depths of the feeding channel 11 in the kettle body 5, the raw materials can be directly blown into different depths of the solvent through the feeding channel 11, thereby preventing the raw materials from accumulating and floating on the solvent liquid surface. The time consumed for uniform stirring is shorter, the stirring effect is better, the reaction effect is also better, and the product quality is therefore better.

[0035] If the discharge port is open, the blowing air source needs to be kept blowing during the stirring process, otherwise the mixed liquid in the kettle body 5 will flow back into the feeding channel 11, which will make the feeding channel 11 difficult to clean. However, keeping blowing will increase unnecessary energy consumption. Figure 3 as well as Figure 5-Figure 8The one-way feeding valve 2 is provided at the discharge port. The one-way feeding valve 2 of this embodiment comprises a fixed valve seat 21, a sliding valve core 22, a first spring 23 and a valve body 26. The valve body 26 is fixedly provided at the discharge port, the fixed valve seat 21 is fixedly connected to the valve body 26, the sliding valve core 22 is slidably connected to the fixed valve seat 21, and the first spring 23 is respectively connected to the sliding valve core 22 and the fixed valve seat 21, so as to provide the sliding valve core 22 with the elastic force required to block the discharge port. Figure 8 As shown, when the blowing air source blows air to the feeding channel 11 to feed the material, the sliding valve core 22 moves outward under the push of the air flow to open the discharge port to form the discharge channel 111, and the raw material can be blown out from the discharge channel 111, see Figure 6 The outer end of the fixed valve seat 21 is hollow. Figure 7 , Figure 8 The reason why the one-way feed valve 2 is shown to be closed at its outer end is the sectional view angle. Figure 7 As shown, when the blowing air source stops blowing air into the feeding channel 11, the sliding valve core 22 moves inward and resets under the action of the first spring 23 to block the discharge port, and the discharge channel 111 is closed, thereby preventing the mixed liquid from flowing back into the feeding channel 11 from the discharge port. The discharge port is blocked by setting a one-way feeding valve 2 at the discharge port. When feeding, the one-way feeding valve 2 is pushed open by the airflow of the blowing air source, so that normal feeding can be performed. When the feeding stops, the one-way feeding valve 2 is automatically closed under the action of the first spring 23, thereby preventing the mixed liquid from flowing back into the feeding channel 11, and also avoiding unnecessary energy consumption caused by the need for the blowing air source to keep blowing. At the same time, since the agitator 1 extends into the interior of the kettle body 5 and is always rotating, if it is to be set as an electrically controlled valve, it will face the problem of how to route the wires. The one-way feeding valve 2 provided in this embodiment has the advantage of not requiring a power drive, and there is no need to consider the routing problem. It should be noted that the inner and outer directions defined in this article are specifically that the rotating axis of the agitator is the inner side and the direction away from the rotating axis is the outer side.

[0036] When the raw materials are poorly ground or aggregated due to moisture, they tend to form large particles and stay in the discharge channel 111, resulting in the one-way feeding valve 2 not being closed tightly, the sealing performance being reduced, and the mixed liquid easily entering the feeding channel 11. Figure 6-Figure 10The one-way feeding valve 2 of this embodiment further includes a rotating turbine 24 and a rotating scraper 25. The rotating turbine 24 includes a turbine shaft 241 and a turbine body 242. The turbine shaft 241 is rotatably connected to the sliding valve core 22 through a bearing. The turbine body 242 is provided with a plurality of rotating blades 245. The number of the rotating blades 245 is not limited here. When the airflow flows through the rotating blades 245, the rotating turbine 24 can be driven to rotate. A scraper airway 2421 is provided in the turbine body 242. The rotating scraper 25 is slidably connected in the scraper airway 2421 so as to be able to extend and retract the turbine body 242. When the one-way feeding valve 2 opens the discharge port, the airflow flows through the rotating blades 245 to drive the rotating turbine 24 to rotate. The rotating scraper 25 extends to the discharge channel 111 under the centrifugal action, thereby cleaning the raw materials, especially the large particles, that stay in the discharge channel 111 during the rotation of the rotating turbine 24. By arranging an airflow-driven rotating turbine 24 and a rotating scraper 25 on the one-way feeding valve 2, the rotating turbine 24 drives the rotating scraper 25 to extend while rotating to break up the large particles of raw materials staying in the discharge channel 111, allowing them to be blown away by the airflow, thereby avoiding the reduction of the sealing performance of the one-way feeding valve 2 due to the raw materials staying at the discharge port.

[0037] If the position where the raw material stays happens to block the rotating scraper 25, the centrifugal force brought by the rotation of the turbine 24 may not be enough to drive the rotating scraper 25 to the discharge channel 111, resulting in the failure of the rotating scraper 25, and the purpose of cleaning the discharge channel 111 cannot be achieved, and the reliability is not high. Fig. 9As shown, a turbine cylinder seat 211 is further provided in the fixed valve seat 21 of the present embodiment, a driving air cavity 212 is provided in the turbine cylinder seat 211, a turbine wheel shaft 241 is sleeved with the turbine cylinder seat 211 and extends into the driving air cavity 212, a connecting air passage is further provided in the turbine wheel shaft 241, the connecting air passage comprises a driving and extending air passage 2411 and a driving and contracting air passage 2412, both the driving and extending air passage 2411 and the driving and contracting air passage 2412 are connected to the scraper air passage 2421 and the driving air cavity 212, when the sliding valve core 22 is pushed outward by the air flow, the driving turbine 24 rotates and moves outward with the sliding valve core 22, the turbine wheel shaft 241 moves outward and compresses the air in the driving air cavity 212 to generate air pressure, and the air pressure acts on the rotating scraper 25 via the connecting air passage and the scraper air passage 2421, so that the rotating scraper 25 extends to the discharge channel 111 under the joint drive of the centrifugal action and the air pressure. When the sliding valve core 22 moves inwards to reset under the action of the first spring 23, the driving turbine 24 moves inwards with the sliding valve core 22, and the turbine wheel shaft 241 moves inwards to expand the driving air cavity 212 to generate negative pressure, and the negative pressure drives the rotating scraper 25 to retract the turbine wheel body 242 via the connecting air channel and the scraper air channel 2421. By setting the rotating scraper 25 in a telescopic form, and providing the driving air cavity 212, the scraper air channel 2421 and the connecting air channel, the power when the one-way feeding valve 2 is opened is used to compress the driving air cavity 212 to generate air pressure, so that the rotating scraper 25 is extended under the joint drive of air pressure and centrifugal action, so that the rotating scraper 25 can be extended more successfully and the reliability is higher.

[0038] When the rotating speed of the driving turbine 24 is low, the speed at which the rotating scraper 25 is driven to rotate is low, which may result in the rotating scraper 25 having a poor effect of breaking up large particles of raw materials, and may also cause the rotating scraper 25 to be stuck by large particles of raw materials, causing the driving turbine 24 to be unable to rotate. Figure 9-10 The retracting airway 2412 of this embodiment is also provided with a one-way vent valve 2413, and the conducting direction of the one-way vent valve 2413 is from the retracting airway 2412 to the driving air chamber 212. The driving turbine 24 of this embodiment is also provided with an airway switch assembly, which includes a switch valve core 243 and a second spring 244. The switch valve core 243 of this embodiment is provided with a through hole 2431. The switch valve core 243 can block the extension airway 2411 to close the extension airway 2411, and can slide to connect the through hole 2431 to the extension airway 2411. The second spring 244 is connected to the switch valve core 243. In this embodiment, the second spring 244 is a tension spring, which can pull the switch valve core 243 to reset and close the extension airway 2411. Its initial state is to drive the switch valve core 243 to keep closing the extension airway 2411.

[0039] like Figure 7 and Fig. 9As shown, since the initial state of the driving and extending airway 2411 is blocked and closed by the switch valve core 243, the driving air chamber 212 is in a closed state at this time, and the driving turbine 24 needs a certain pressure to compress the gas in the driving air chamber 212. The air pressure provided by the blowing air source is gradually increased. The air pressure provided at the beginning is not enough to drive the sliding valve core 22 to drive the driving turbine 24 to compress the driving air chamber 212, and the sliding valve core 22 will not move outward immediately. Figure 8 and Fig.10 As shown, when the air pressure provided by the blowing air source increases to a certain extent, it is sufficient to drive the sliding valve core 22 to drive the driving turbine 24 to compress the driving air chamber 212, and the sliding valve core 22 moves outward, the discharge channel 111 is opened to form an airflow, and the driving turbine 24 starts to rotate under the drive of the airflow. At this time, the switch valve core 243 is still blocked by the second spring 244 to block the driving and extending air channel 2411. After the driving turbine 24 reaches a preset speed, the switch valve core 243 overcomes the pulling force of the second spring 244 under the centrifugal action and is thrown out, so that the through hole 2431 is connected to the driving and extending air channel 2411, and the air pressure in the driving air chamber 212 is driven by the driving and extending air channel 2411. The air channel 2411 and the scraper air channel 2421 act on the rotating scraper 25 to push the rotating scraper 25 out; after the blowing air source gradually stops blowing, the sliding valve core 22 begins to move inward under the action of the first spring 23, and the speed of the driving turbine 24 begins to decrease. When its speed is lower than the preset speed, the switch valve core 243 is reset under the action of the second spring 244 to close the extension air channel 2411, and the sliding valve core 22 drives the driving turbine 24 to move inward to expand the driving air cavity 212. At this time, the one-way vent valve 2413 is opened, and the negative pressure generated by the expansion of the driving air cavity 212 pulls the rotating scraper 25 back through the contraction air channel 2412. By setting an airway switch assembly in the driving and extending airway 2411, the second spring 244 is used to keep the switch valve core 243 blocking the driving and extending airway 2411. When the driving turbine 24 exceeds a certain rotation speed, the centrifugal force on the switch valve core 243 is sufficient to overcome the elastic force of the second spring 244 and be thrown out, thereby opening the driving and extending airway 2411, and the driving air cavity 212 is able to drive the rotating scraper 25 to extend, so that the rotating scraper 25 is extended only when the driving turbine 24 reaches a higher rotation speed, and can break up large particles of raw materials at a higher speed, reducing the possibility of being stuck by large particles of raw materials due to insufficient rotation speed.

[0040] Finally, it should be noted that the above embodiment is only used to illustrate the technical solution of the present invention, rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiment, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
