Description

Technical Field

[0001] The utility model relates to the field of synthetic leather production, in particular to an air supply and filtering system of a constant temperature and humidity unit. Background Art

[0002] In synthetic leather manufacturers, the precise operation of quality inspection equipment plays a crucial role in ensuring product quality. Constant temperature and humidity rooms, crucial locations for storing critical equipment such as EDX analyzers, GCMS analyzers, IPC analyzers, and mid-infrared spectrometers, require stable environmental conditions that directly impact the accuracy of test data. These high-precision testing equipment have extremely stringent environmental requirements; even slight fluctuations in temperature and humidity can lead to skewed test results. To ensure reliable test data, the room's temperature and humidity must be precisely controlled at all times. The current approach of centralized air conditioning, electrode humidifiers, and auxiliary heating in winter using auxiliary heating pipes theoretically meets the requirements for constant temperature and humidity. However, problems frequently arise in practice. During operation, the constant temperature and humidity units often fail to effectively dissipate the heat generated by the auxiliary heating, triggering thermistor alarms and forcing the equipment to shut down. This severely impacts the room's temperature and humidity control, preventing the required constant temperature and humidity. A careful inspection revealed that the root cause of the problem was a clogged air inlet filter. When the filter is clogged, the air flow is significantly reduced, directly impacting the efficiency of temperature and humidity transmission. This insufficient air flow not only hinders heat transfer but also significantly reduces humidification effectiveness. In this situation, the room's temperature and humidity cannot be stabilized within a suitable range, failing to provide an ideal operating environment for testing equipment. For synthetic leather companies, this means increased unreliability in test results, potentially leading to misleading judgments about product quality, and thus impacting production decisions and market competitiveness.

[0003] Therefore, there is an urgent need for a more efficient and intelligent large-scale constant temperature and humidity unit air supply filtration system. This system should be able to monitor filter blockage in real time, issue timely alarms, and take appropriate measures to ensure sufficient air flow. Furthermore, the system should have optimized temperature and humidity control capabilities, enabling precise adjustments based on the actual needs of testing equipment, providing a stable and reliable constant temperature and humidity environment for critical testing equipment, ensuring smooth testing operations. Utility Model Content

[0004] The purpose of the utility model is to provide an air supply filtration system for a constant temperature and humidity unit. By setting up an air pressure sensor and an alarm system, problems such as filter cotton blockage can be discovered in a timely manner, thereby avoiding overheating and damage of the equipment due to poor air circulation, thereby solving the above problems.

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

[0006] A constant temperature and humidity air supply filtration system includes a centralized air conditioner for cooling and an electrode humidifier for humidification. In winter, auxiliary heating tubes provide auxiliary heating. The centralized air conditioner effectively cools the indoor space, ensuring a comfortable temperature even in hot weather. The electrode humidifier increases air humidity, releasing water vapor to regulate indoor humidity levels. In winter, the auxiliary heating tubes provide additional heat to keep the indoor temperature from dropping too low.

[0007] The auxiliary heating tube draws heat in through an internal induced draft fan. The induced draft fan quickly draws heat generated by the auxiliary heating tube into the interior space, improving heating efficiency. An air inlet duct is located on the outside of the auxiliary heating tube, and a filter is installed at the air inlet inside the duct. The duct allows outside air to enter the system, while the filter filters out dust, impurities, and other contaminants, ensuring clean air entering the room.

[0008] A wind pressure sensor is installed next to the filter cotton, connected to a wind pressure controller. An audible and visual alarm is mounted on the top of the wind pressure controller. The wind pressure sensor monitors changes in wind pressure at the air inlet in real time. When the wind pressure falls below a set threshold, indicating a possible blockage in the filter cotton, resulting in poor air circulation, the wind pressure sensor sends an alarm signal to the wind pressure controller. Upon receiving the alarm signal, the wind pressure controller triggers an audible and visual alarm, alerting the user to address the problem promptly.

[0009] The electrode humidifier is equipped with a humidity sensor that collects humidity data and transmits it to the electrode humidifier, thereby regulating indoor humidity. The humidity sensor accurately detects the humidity level of the indoor air and transmits this data to the electrode humidifier. Based on the humidity data received, the electrode humidifier automatically adjusts the humidification amount to ensure that the indoor humidity is always within an appropriate range.

[0010] The wind pressure controller collects and stores alarm information. It not only receives alarm signals from the wind pressure sensor but also stores these alarms. This allows users to review the system's alarm history at any time, allowing them to better understand the system's operation and identify potential problems.

[0011] The system features a monitoring interface that graphically displays various parameters and status. Users can view wind pressure changes, temperature, and humidity information at any time through the monitoring interface, allowing them to quickly understand the system's operating status. The monitoring interface displays various system parameters and status in an intuitive graphical format, allowing users to clearly understand the system's operating status. Users can view information such as wind pressure changes, temperature, and humidity at any time through the monitoring interface, allowing them to keep abreast of the system's operating status.

[0012] The monitoring interface is transmitted to the user end via a wireless communication module. The user can view the system's operating status in real time through a mobile phone, computer, or other device, receive alarm information, and remotely control the start and stop of equipment such as auxiliary heating pipes and induced draft fans, thereby achieving intelligent remote management. The wireless communication module enables data from the monitoring interface to be transmitted to the user's mobile phone, computer, or other device. The user can view the system's operating status in real time and receive alarm information from anywhere with an Internet connection. At the same time, the user can also use the remote control function to start and stop equipment such as auxiliary heating pipes and induced draft fans, achieving intelligent remote management and improving the convenience and operability of the system.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] By installing filter cotton at the air inlet, dust, impurities and other pollutants in the air can be effectively filtered out, improving the quality of air entering the room.

[0015] The installation of wind pressure sensors and alarm systems can promptly detect problems such as filter blockage, preventing equipment overheating and damage caused by poor air circulation. Furthermore, the use of humidity sensors and electrode humidifiers can accurately control indoor humidity, preventing damage to equipment caused by excessively high or low humidity.

[0016] The use of a monitoring interface and wireless communication module allows users to view the system's operating status in real time, receive alarm information, and perform remote control via mobile phones, computers, and other devices. This greatly improves the system's intelligence and management efficiency, reduces the workload of manual inspections, and lowers management costs.

[0017] The optimized design of the auxiliary heating tube and induced draft fan improves heating efficiency and reduces energy consumption. Furthermore, precise control of the electrode humidifier prevents over-humidification and conserves water resources. Furthermore, the use of environmentally friendly filter materials reduces environmental pollution, meeting the requirements of sustainable development. BRIEF DESCRIPTION OF THE DRAWINGS
