Description

Technical Field

[0001] This utility model relates to the technical field of heat dissipation and gas treatment systems for stirred mixing vessels, and in particular to a heat dissipation and gas treatment system for stirred mixing vessels. Background Technology

[0002] In the chemical industry, reaction vessels are essential equipment, mainly used for mixing and reaction in the production process. Many chemical reactions need to be carried out in reaction vessels, and the stirring paddle driven by a motor is used to uniformly stir the reactants to make the reaction more thorough.

[0003] Existing reactors include a motor and a stirring shaft connected to the motor output shaft via a gearbox. Part of the stirring shaft is located outside the reactor, which makes it prone to safety accidents and injuries to workers when it rotates at high speed during operation. Some reactors use a sealing cover to seal this part of the stirring shaft. However, during stirring, the heat dissipation is poor due to the sealed state, and it is not convenient to clean and maintain it.

[0004] Therefore, a reactor stirring shaft protection device with authorization announcement number CN209791544U has emerged, which discloses that it includes a reactor body, a support is provided on the top of the reactor body, the support includes two circular and parallel top plates and bottom plates, two relatively vertical arc-shaped support plates are fixedly connected between the top plates and the bottom plates, a heat dissipation groove is formed between the two support plates, two arc-shaped protective covers are slidably connected between the top plates and the bottom plates, a number of heat dissipation vents are evenly opened on the surface of the protective covers, a motor is provided on the top of the top plate, the output shaft of the motor is fixedly connected to a stirring shaft, the stirring shaft passes through the support and extends into the interior of the reactor body.

[0005] Although the protective cover can dissipate heat and protect the exposed part of the stirring shaft, preventing workers from getting too close and causing safety accidents, it still has the following drawbacks:

[0006] Although heat dissipation is achieved through vents, the slow airflow inside and outside the reactor body results in poor heat dissipation. Furthermore, odors are not properly addressed during material feeding, leading to a strong odor within the workshop. Additionally, material feeding and inspection cannot be carried out normally in dim lighting conditions.

[0007] Therefore, in this utility model patent application, the applicant has carefully studied a heat dissipation and gas treatment system for a stirring mixing vessel to solve the above problems. Utility Model Content

[0008] This utility model addresses the shortcomings of the existing technology by providing a heat dissipation and gas treatment system for a mixing vessel. This system facilitates the upward movement of hot air from the heat dissipation holes towards the gas collection hood and into the extraction pipe, thereby improving heat dissipation and alleviating the problem of strong odors and excessive heat in the workshop. Furthermore, it eliminates the need for manual operation of the lighting, demonstrating a high degree of automation and significantly improving the convenience and efficiency of lighting use.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A heat dissipation and gas treatment system for a stirred mixing vessel includes a reactor body. A support is mounted on the top of the reactor body, and several heat dissipation vents are evenly distributed on the front end face of the support. A motor is mounted on the top of the support, and the output shaft of the motor is fixedly connected to a stirring shaft. The stirring shaft passes through the support and extends into the interior of the reactor body.

[0011] The top of the reactor body has a feeding port, and a sealing cover is installed at the feeding port. A gas collection hood is provided above the reactor body to collect hot air coming out of the heat dissipation port and gas coming out of the feeding port after the sealing cover is opened.

[0012] The gas collection hood is suspended above the closed cover. An extraction pipe is connected to the top of the gas collection hood, and a light is installed on the inner top of the hood. A human body sensor module is installed on the front face of the gas collection hood.

[0013] It also includes a main control unit, which is connected to the human body sensing module and the lighting lamp respectively, so as to control the switching on and off of the lighting lamp after sensing a human body within the monitoring range.

[0014] As a preferred embodiment, the gas collection hood has a gas collection hood inlet that is arranged inclined from top to bottom and inward.

[0015] As a preferred embodiment, the cover is provided with a viewing window.

[0016] As a preferred embodiment, both the feed port and the gas collection hood are located directly in front of the motor.

[0017] As a preferred embodiment, the main control unit is located on the outer side of the gas collection hood.

[0018] As a preferred embodiment, the system also includes a hygrometer connected to the main control unit.

[0019] As a preferred embodiment, it also includes a wireless module for wirelessly connecting to cloud servers and mobile terminals, with the main control unit connected to the wireless module.

[0020] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, the main feature is that the exhaust pipe accelerates the gas flow below the gas collection hood, which is conducive to the hot air from the heat dissipation holes rising towards the gas collection hood and entering the exhaust pipe, thus improving the heat dissipation effect. At the same time, when feeding materials, the odor of the materials can be drawn upward, thereby alleviating the situation of strong odor and high heat in the workshop. Moreover, through the cooperation of the human body sensing module and the main control unit, the lights can be turned on in advance when a human body is sensed, without the need for manual operation. The high degree of intelligence greatly improves the convenience of using the lights and the work efficiency.

[0021] Secondly, by setting a viewing window on the sealed cover, it is easy for personnel to directly observe the stirring situation inside the reactor body in real time;

[0022] Furthermore, the wireless module enables wireless communication between the cloud server and mobile terminal, allowing relevant personnel to view the triggered sensing time and lighting switch time in a timely manner, facilitating real-time understanding of the situation. In particular, the hygrometer allows for timely monitoring of the humidity of the environment surrounding the reactor, enabling a decision on whether to continue processing, thus providing good flexibility.

[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] like Figures 1 to 3 As shown, a heat dissipation and gas treatment system for a stirred mixing vessel includes a reaction vessel body 10.

[0043] The top of the reactor body 10 has a feed port 11, and a closable cover 12 is installed at the feed port 11. The closable cover 12 is provided with a viewing window 13. Through the viewing window 13, it is convenient to observe the stirring situation inside the reactor body 10 in real time.

[0044] The top of the reactor body 10 is provided with a support 20, and the front end face of the support 20 is provided with a plurality of heat dissipation vents 21. The top of the support 20 is provided with a motor 30, and the feeding port 11 is located directly in front of the motor 30.

[0045] The output shaft of the motor 30 is fixedly connected to a stirring shaft 31, which passes through the bracket 20 and extends into the interior of the reactor body 10.

[0046] In this embodiment, three motors 30 are arranged side-by-side, and correspondingly, three stirring shafts 31 are provided, with each motor 30 connected to one stirring shaft 31. Each stirring shaft 31 has stirring rods 32 evenly distributed longitudinally and arranged in a staggered manner. Powerful stirring is achieved through the multiple staggered stirring shafts 31.

[0047] Above the reactor body 10 is a gas collection hood 40 for collecting hot air coming out of the heat dissipation port 21 and gas coming out of the feed port 11 after the sealing cover 12 is opened; the gas collection hood 40 is located directly in front of the motor 30.

[0048] The gas collecting hood 40 is suspended above the sealing cover 12, and the top of the gas collecting hood 40 is connected to the exhaust pipe 41. Several heat dissipation vents 21 of the protective cover face the area below the gas collecting hood 40. The exhaust pipe 41 accelerates the gas flow below the gas collecting hood 40, which helps the hot air from the heat dissipation vents 21 to rise towards the gas collecting hood 40 and enter the exhaust pipe 41. At the same time, when feeding material from the feeding port 11 after opening the sealing cover 12, the arrangement of the gas collecting hood 40 and the exhaust pipe 41 can also draw the odor of the material upwards. Therefore, it can alleviate the situation of strong odor and high heat in the workshop.

[0049] The gas collection hood 40 has a gas inlet 42 that is arranged inclined inward from top to bottom. A lighting lamp 43 is provided on the inner top of the gas collection hood 40. The lighting lamp 43 facilitates the feeding and inspection of materials.

[0050] It also includes a main control unit 44, a hygrometer 45, and a wireless module 46 for wirelessly connecting to the cloud server 51 and the mobile terminal 52. The main control unit 44 is connected to the wireless module 46 to enable communication between the mobile terminal 52 and the cloud server 51.

[0051] Both the main control unit 44 and the hygrometer 45 are located on the outer surface of the gas collection hood 40. The hygrometer 45 is connected to the main control unit 44. The hygrometer 45 can detect the humidity of the environment in which the reactor body 10 is located in real time and send the data to the main control unit 44 promptly. The main control unit 44 can upload the data to the cloud server 51 via a wireless module 46. Alternatively, to enhance real-time alerting, an alarm 47 can be connected to the main control unit 44. When the humidity reaches a preset humidity threshold, the alarm 47 will sound to alert personnel. Preferably, the alarm 47 can be a sound alarm 47, a light alarm 47, or a combination of sound and light alarms.

[0052] The front end of the gas collection hood 40 is provided with a human body sensing module 48. The main control unit 44 is connected to the human body sensing module 48 and the lighting lamp 43 respectively so as to control the switch of the lighting lamp 43 after sensing a human body within the monitoring range.

[0053] When a person enters the sensing range, the human body sensing module 48 senses the human body and generates a sensing signal, which is then transmitted to the main control unit 44. The main control unit 44 generates a control signal based on the sensing signal to turn on the lighting 43. When the human body leaves the sensing range, the human body sensing module 48 generates no sensing signal, and the main control unit 44 controls the lighting 43 to turn off.

[0054] In this embodiment, the human body sensing module 48 includes an infrared sensor 481 and a camera 482. When the infrared sensor 481 senses a person within its monitoring range, the camera 482 takes a picture and simultaneously generates a sensing signal. The image and sensing signal are then sent to the main control unit 44. The main control unit 44 generates a control signal based on the sensing signal to control the lighting 43 to turn on. Simultaneously, the on-time and frequency of the lighting 43, the time and frequency of triggering the human body sensing, and the image are all uploaded to the cloud server 51 via the wireless module 46 for viewing by authorized personnel. The status and humidity of the lighting 43 can also be remotely monitored via the mobile terminal 52.

[0055] The key design feature of this utility model is that the exhaust pipe accelerates the gas flow below the gas collection hood, which helps the hot air from the heat dissipation holes rise towards the gas collection hood and enter the exhaust pipe, thus improving the heat dissipation effect. At the same time, when feeding materials, it can draw the odor of the materials upward, thereby alleviating the situation of strong odor and high heat in the workshop. Moreover, through the cooperation of the human body sensing module and the main control unit, the lights can be turned on in advance when a human body is sensed, without the need for manual operation. The high degree of intelligence greatly improves the convenience of using the lights and the work efficiency.

[0056] Secondly, by setting a viewing window on the sealed cover, it is easy for personnel to directly observe the stirring situation inside the reactor body in real time;

[0057] Furthermore, the wireless module enables wireless communication between the cloud server and mobile terminal, allowing relevant personnel to view the triggered sensing time and lighting switch time in a timely manner, facilitating real-time understanding of the situation. In particular, the hygrometer allows for timely monitoring of the humidity of the environment surrounding the reactor, enabling a decision on whether to continue processing, thus providing good flexibility.

[0058] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
