Description

Technical Field

[0001] This invention relates to the field of environmental governance technology, specifically to a targeted environmental governance intelligent control device and control method for complex clean spaces. Background Technology

[0002] Complex clean spaces are special spaces with extremely high environmental control requirements. They need to strictly remove pollutants such as airborne particles, harmful gases, and bacteria, and precisely control parameters such as cleanliness, temperature, humidity, pressure, airflow speed and direction, noise, electromagnetic interference, micro-vibration, illuminance, and static electricity. Such spaces are usually used in fields with extremely strict requirements for production or experimental environments, such as semiconductor manufacturing, biopharmaceutical production, and precision instrument assembly. Complex clean spaces are generally equipped with environmental control devices. Traditional clean space environmental control devices mostly adopt a global control method, which monitors environmental parameters through sensors at fixed locations and combines them with unified purification equipment for overall treatment, so that the environmental parameters of the entire space reach a certain stable level. However, traditional environmental control devices typically employ a holistic monitoring approach, which makes it difficult to achieve precise environmental monitoring and targeted regulation of different areas. When implementing global regulation, over-purification can easily occur, leading to energy waste. Furthermore, prolonged high-load operation of the equipment can increase maintenance costs. Therefore, to address these issues, a targeted environmental governance intelligent control device and control method for complex clean spaces is proposed. Summary of the Invention

A limit hollow tube is sleeved on the outer side of the grooved transmission wheel. A limit spring is provided inside the limit hollow tube.

[0005] As a further optimization of the present invention, the housing includes a grooved shell, a sliding groove is provided on the inner side of the grooved shell, a threaded groove is provided on one side of the grooved shell, and a notch is provided on one side of the grooved shell. The vertical cross-sectional shape of the sliding groove is the same as the longitudinal projection of the limiting protrusion, and the shape of the notch is the same as the shape of the limiting protrusion.

[0006] As a further optimization of the present invention, the filter housing has a plurality of uniformly spaced strip-shaped holes at its bottom end, a portion of the filter housing is exposed on the outside of the grooved shell, the torsion handle is located on the end of the filter housing exposed on the outside of the grooved shell, and the outer side of the cleaning adsorption strip is in close contact with the inner side of the filter housing.

[0007] As a further optimization of the present invention, the toothed ring sleeve and the cleaning adsorption strip are on the same straight line, the included angle between the toothed ring sleeve and the grooved transmission wheel is 90°, the toothed ring sleeve is inserted into the limiting groove, and the shape of the toothed ring sleeve is exactly the same as the opening shape of the limiting groove.

[0008] As a further optimization of the present invention, the rubber wheel and the impeller are parallel to each other, the impeller is fixedly connected to a grooved shell, and a plurality of blades are arranged in a ring and evenly spaced on the outside of the impeller.

[0009] As a further optimization of the present invention, the grooved drive wheel and the paddle wheel are parallel to each other, a portion of the grooved drive wheel is disposed in the limiting hollow tube, a grooved shell is fixedly connected to one side of the limiting hollow tube, and a grooved shell is fixedly connected to one end of the limiting spring.

[0010] As a further optimization of the present invention, the adjusting mechanism includes an arc-shaped plate, a threaded rod rotatably connected to the inner side of the arc-shaped plate, and a handwheel fixedly connected to the outer side of the threaded rod.

[0011] As a further optimization of the present invention, the arc plate is arc-shaped, the bottom end of the arc plate is in contact with the bottom end of the inner side of the grooved shell, the threaded rod is spirally engaged with the handwheel, and the handwheel is located on the outer side of the grooved shell.

[0012] As a further optimization of the present invention, the grooved shell is disposed above the exhaust fan, the impeller is disposed on one side of the exhaust fan, and the arc-shaped plate is disposed on the side of the exhaust fan away from the impeller.

[0013] A control method for a targeted environmental management intelligent control device for complex clean spaces: S1: Control and operation of the targeted treatment module: Laser particulate matter sensors, ultraviolet intensity probes, gas sensors, and temperature and humidity sensors are distributed in various key areas of the clean space to monitor environmental parameters within the clean space and transmit the monitoring data to the control panel. The control panel analyzes and processes the collected data, generates environmental treatment strategies, and controls the start-up of the targeted treatment module. S2: Exhaust fan draws air from the interior space of the frame: When the exhaust fan is turned on, it draws the air inside into the housing. The air that enters the housing enters the inner side of the filter housing through the strip-shaped hole at the bottom of the filter housing. After being adsorbed and purified by the cleaning adsorption strip on the inner side of the filter housing, it is discharged from the opening at the top of the housing. S3: The transmission mechanism starts and drives the housing to move together: The servo motor is started through the control panel or the preset start program in the control panel, so that the main shaft of the servo motor rotates and drives the rubber wheel fixedly connected to it to rotate. The rotation of the rubber wheel will drive the impeller set on the side of the exhaust fan to rotate through the lower transmission belt. At the same time, the rotation of the impeller drives the grooved transmission wheel to rotate through the upper transmission belt. The rotation of the grooved transmission wheel drives the toothed ring sleeve inserted in the limit slot to rotate. The rotation of the toothed ring sleeve drives the cleaning adsorption strip set on the inside of the filter housing to rotate. S4: The adjustment mechanism changes the airflow space inside the housing: Turning the handwheel drives the threaded rod to rotate, which changes the relative position of the threaded rod and the grooved shell. At the same time, the threaded rod pushes the arc plate to move inside the housing, and the gas entering the housing flows along the arc plate to the inside of the filter housing. S5: Removal and cleaning of the adsorption strip: Turn the handle to rotate the filter housing and the limiting protrusion fixed to the outside of the filter housing, then pull the filter housing out of the housing and perform deep cleaning or replacement of the adsorption strip.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, through the coordinated layout of laser particulate matter sensor, ultraviolet intensity probe, gas sensor and temperature and humidity sensor, the device can capture local environmental parameters in real time for dynamic analysis, accurately identify the location of pollution source and pollutant type, and form a high-intensity purification flow field in the local area to quickly adsorb pollutants. This breaks through the "one-size-fits-all" purification strategy of traditional environmental control devices, avoids ineffective full-space purification, saves energy and reduces equipment wear. 2. In this invention, through the transmission mechanism, the device correlates the rotation speed of the cleaning adsorption strip with the rotation speed of the paddle wheel. This linkage mechanism matches the increase in airflow velocity with the rotation speed of the cleaning adsorption strip. When the environmental monitoring sensor detects a high concentration of pollutants in the air, the control panel can increase the speed of the servo motor, thereby accelerating the rotation speed of the paddle wheel and the cleaning adsorption strip and enhancing the purification intensity. Conversely, when the pollutant concentration is low, the rotation speed can be reduced to reduce energy consumption. 3. In this invention, through the cleaning and adjustment mechanisms, the device can perform deep cleaning or replacement of the cleaning adsorption strip by rotating the handle and pulling out the filter housing. This design makes the maintenance of the equipment more convenient and quick, without the need for complicated disassembly and assembly processes, greatly reducing the difficulty and time of maintenance. At the same time, the adjustment mechanism can manually adjust the air flow space inside the housing by rotating the handwheel to drive the threaded rod and the arc plate, thereby changing the residence time and flow speed of the air in the housing, and playing the role of manually adjusting the purification effect of the targeted treatment module.

[0017] Please see Figure 1-9 The present invention provides a technical solution: A targeted environmental remediation intelligent control device and method for complex clean spaces includes a frame 1, a laser particulate sensor 2, an ultraviolet intensity probe 3, a gas sensor 4, a temperature and humidity sensor 5, and a control panel 6. A targeted remediation module 7 is fixedly mounted on a partition on one side of the frame 1. The targeted remediation module 7 includes a housing 71, a cleaning mechanism 72 installed inside the housing 71, a transmission mechanism 73 on one side of the housing 71, an adjustment mechanism 74 installed inside the housing 71, and an exhaust fan 75 installed inside the housing 71. The cleaning mechanism 72 includes a filter housing 721, a limiting protrusion 722 fixedly connected to the outside of the filter housing 721, a torsion handle 723 fixedly connected to one end of the filter housing 721, a cleaning adsorption strip 724 rotatably mounted inside the filter housing 721, and a toothed ring sleeve 725 fixedly connected to the outside of one end of the cleaning adsorption strip 724. The transmission mechanism 73 includes a servo motor 731, and a rubber wheel fixedly connected to the outside of the main shaft of the servo motor 731. 732, a lower drive belt 733 is fitted on the outer side of the rubber wheel 732, a paddle wheel 734 is installed inside the lower drive belt 733, an upper drive belt 735 is fitted on the outer side of the paddle wheel 734, a grooved drive wheel 736 is installed inside the upper drive belt 735, a limit slot 737 is opened inside the grooved drive wheel 736, a limit hollow tube 738 is fitted on the outer side of the grooved drive wheel 736, and a limit spring 739 is set inside the limit hollow tube 738. The environmental parameters in the clean space are monitored by laser particulate matter sensor 2, ultraviolet intensity probe 3, gas sensor 4, and temperature and humidity sensor 5 distributed in various key areas of the clean space, and the monitoring data is transmitted to the control panel 6. The control panel 6 can analyze and process the collected data to generate the optimal environmental management strategy, and change the purification intensity by controlling the operation of the targeted treatment module 7. In addition, the targeted treatment module 7 can also be manually adjusted to realize the adjustment mode.

[0018] Please see Figure 2-6 In this embodiment, the housing 71 includes a grooved housing 711, with a sliding groove 712 formed on the inner side of the grooved housing 711, a threaded groove 713 formed on one side of the grooved housing 711, and a notch 714 formed on one side of the grooved housing 711. The vertical cross-sectional shape of the sliding groove 712 is the same as the longitudinal projection of the limiting protrusion 722, and the shape of the notch 714 is the same as the shape of the limiting protrusion 722. The bottom end of the filter housing 721 has a plurality of uniformly and equidistantly distributed strip-shaped holes, and a portion of the filter housing 721 is exposed. The handle 723 is located on the outer side of the grooved shell 711. The outer side of the cleaning adsorption strip 724 is in close contact with the inner side of the filter shell 721. The central axis of the toothed ring sleeve 725 is on the same straight line as the central axis of the cleaning adsorption strip 724. The included angle between the toothed ring sleeve 725 and the grooved drive wheel 736 is 90°. The toothed ring sleeve 725 is inserted into the limiting groove 737. The shape of the toothed ring sleeve 725 is exactly the same as the shape of the limiting groove 737.

[0019] Specifically, the strip-shaped hole at the bottom of the filter housing 721 allows air entering the housing 71 to pass through more effectively and enter the inner side of the filter housing 721. After being adsorbed and purified by the cleaning adsorption strip 724 on the inner side of the filter housing 721, the air is discharged from the opening at the top of the housing 71 and returns to the frame 1, ensuring the air pressure inside the frame 1 and preventing pressure imbalance caused by air purification. The shape and size of the sliding groove 712 are customized according to the design of the limiting protrusion 722 to ensure that the limiting protrusion 722 can slide smoothly in the sliding groove 712. When deep cleaning or replacement of the cleaning adsorption strip 724 is required, the torsion handle 723 can be rotated to drive the filter housing 721 and the limiting protrusion 722 fixedly connected to the outside of the filter housing 721 to rotate, and then the filter housing 721 can be pulled out of the housing 71. The toothed ring sleeve 725 matches the limiting slot 737 so that the components can form a fit.

[0020] Please see Figure 3-8 In this embodiment, the rubber wheel 732 and the paddle wheel 734 are parallel to each other. The paddle wheel 734 is fixedly connected to the grooved shell 711. Several blades are arranged in a ring and are evenly distributed on the outside of the paddle wheel 734. The grooved drive wheel 736 is parallel to the paddle wheel 734. A part of the grooved drive wheel 736 is arranged in the limiting hollow tube 738. The grooved shell 711 is fixedly connected to one side of the limiting hollow tube 738. One end of the limiting spring 739 is fixedly connected to the grooved shell 711.

[0021] Specifically, the servo motor 731 spindle rotates and drives the rubber wheel 732 fixedly connected to it to rotate. The rotation of the rubber wheel 732 drives the impeller 734 located on one side of the exhaust fan 75 to rotate via the lower transmission belt 733. The rotation of the impeller 734 can accelerate the airflow into the housing 71. At the same time, the rotation of the impeller 734 drives the grooved transmission wheel 736 to rotate via the upper transmission belt 735. The rotation of the grooved transmission wheel 736 drives the toothed ring sleeve 725 inserted in the limiting slot 737 to rotate. The rotation of the toothed ring sleeve 725 drives the cleaning adsorption strip 724 located inside the filter housing 721 to rotate. When the spindle speed of the servo motor 731 increases, the rotation of the cleaning adsorption strip 724 inside the filter housing 721 will also increase, thereby accelerating the purification adsorption effect.

[0022] Please see Figure 4-9In this embodiment, the adjustment mechanism 74 includes an arc-shaped plate 741, a threaded rod 742 rotatably connected to the inner side of the arc-shaped plate 741, and a handwheel 743 fixedly connected to the outer side of the threaded rod 742. The arc-shaped plate 741 is arc-shaped, and the bottom end of the arc-shaped plate 741 is in contact with the bottom end of the inner side of the grooved shell 711. The threaded rod 742 and the handwheel 743 are spirally engaged. The handwheel 743 is located on the outer side of the grooved shell 711. The grooved shell 711 is located above the exhaust fan 75. The impeller 734 is located on one side of the exhaust fan 75. The arc-shaped plate 741 is located on the side of the exhaust fan 75 away from the impeller 734.

[0023] Specifically, rotating the handwheel 743 causes the threaded rod 742 to rotate, changing the relative position of the threaded rod 742 and the grooved shell 711. At the same time, the threaded rod 742 pushes the arc plate 741 to move inside the shell 71. The movement of the arc plate 741 changes the activity space of the air entering the shell 71, thereby changing the residence time of the air in the shell 71. The speed at which the gas entering the shell 71 flows along the arc plate 741 to the inside of the filter shell 721 changes, thus manually adjusting the purification effect of the targeted treatment module 7.
