Description

Technical Field

[0001] This utility model relates to the field of high-efficiency air outlet technology, specifically to a dual high-efficiency air outlet device. Background Technology

[0002] Cleanroom ventilation systems are widely used in industrial environments with high cleanliness requirements. The terminals of these systems typically feature high-efficiency air outlets, with the core component being a high-efficiency filter (HEPA filter), also known as a high-efficiency filter element. This filter performs the final stage of filtration on the air entering the cleanroom, ensuring that the air quality within the cleanroom meets the specified standards.

[0003] In traditional cleanroom ventilation systems, the terminal high-efficiency filters are single-unit structures, and their efficiency and lifespan directly affect the performance of the entire cleanroom system. However, with the continuous development of industrial production, more and more factory workshops are adopting 24-hour continuous production modes, which places higher demands on the stability of the clean environment and the continuity of system operation.

[0004] In continuous production environments, when HEPA filters become clogged, damaged, or reach the end of their service life and require replacement, the cleanroom ventilation system must be shut down for replacement and maintenance. This process is not only time-consuming and labor-intensive, increasing operation and maintenance costs, but also seriously affects the continuity, timeliness, and overall efficiency of production. Utility Model Content

[0005] To overcome the above shortcomings, the purpose of this utility model is to provide a dual high-efficiency air outlet device that does not require shutdown or production stoppage. Through the dual filter element structure and the interlocking control of the electric valve, the filter element can be replaced without stopping production or the machine, ensuring the continuous operation of the clean system.

[0006] Technical solution: This utility model discloses a dual high-efficiency air outlet device, comprising:

[0007] Air ducts installed on the ceiling of the cleanroom;

[0008] At least one set of first air outlets and second air outlets respectively connected to the air duct;

[0009] The first air outlet has a first electric valve, and the end of the first air outlet is connected to a first filter element; the second air outlet has a second electric valve, and the end of the second air outlet is connected to a second filter element.

[0010] The first electric valve and the second electric valve are connected by an electronic interlock device.

[0011] Furthermore, the first air outlet and the second air outlet are connected in parallel.

[0012] Furthermore, the end of the first air outlet is connected to a first air supply box installed in the ceiling of the cleanroom, and the first filter element is installed in the first air supply box; the end of the second air outlet is connected to a second air supply box installed in the ceiling of the cleanroom, and the second filter element is installed in the second air supply box.

[0013] Furthermore, the first air supply box has a first clamping member for clamping the first filter element, and the first clamping member fixes or removes the first filter element by threads; the second air supply box has a second clamping member for clamping the second filter element, and the second clamping member fixes or removes the second filter element by threads.

[0014] Furthermore, the duct has at least a first branch pipe and a second branch pipe, with the first air outlet connected to the first branch pipe and the second air outlet connected to the second branch pipe.

[0015] Furthermore, the first air outlet is connected to the first branch pipe via a first flexible connecting pipe, and the second air outlet is connected to the second branch pipe via a second flexible connecting pipe.

[0016] The beneficial effects of this utility model are as follows:

[0017] (1) By setting two parallel air outlets and using an electronic interlock device to control the first air outlet and the second air outlet, this utility model ensures that when the filter element of one air outlet is replaced, the other air outlet can continue to operate and supply air, thereby avoiding system shutdown and realizing non-stop production.

[0018] (2) The filter element can be installed stably and securely by using the threaded clamping parts inside the air supply box, and it is easy to disassemble and maintain manually, reducing the risk of operation and maintenance and improving the replacement efficiency.

[0019] (3) An electronic interlock device is used to link the electric valve to ensure that only one air supply path is allowed to be open at any time, so as to avoid airflow conflict or short circuit problems and improve the intelligence and safety of system operation. Attached Figure Description

[0025] like Figure 1 As shown, this utility model discloses a dual high-efficiency air outlet device, comprising:

[0026] Air duct 1 installed on the ceiling of the cleanroom;

[0027] At least one set of first air outlet 21 and second air outlet 22 respectively connected to the air duct 1;

[0028] The first air outlet 21 has a first electric valve 31, and the end of the first air outlet 21 is connected to a first filter element 511. The second air outlet 22 has a second electric valve 32, and the end of the second air outlet 22 is connected to a second filter element 521.

[0029] The first electric valve 31 and the second electric valve 32 are connected by an electronic interlock device 4.

[0030] With the above structure, the duct 1 is used to transport air treated by the air conditioning and pretreatment system. At least one set of first air outlet 21 and second air outlet 22 are connected to the duct 1, forming two independent air supply paths. First electric valve 31 and second electric valve 32 are respectively installed inside the first air outlet 21 and second air outlet 22 to control the opening or closing of their respective air supply channels. Electronic interlock device 4 controls the interlocking operation of the first electric valve 31 and second electric valve 32, ensuring that only one air outlet is open at any given time, preventing system chaos or failure. First filter element 511 and second filter element 521 can be installed at the ends of the first air outlet 21 and second air outlet 22 respectively, for final filtration of the air supplied to the cleanroom to ensure that air cleanliness meets standards. This invention, through its dual-path structure and interlocking control of electric valves, allows switching to the other air outlet for air supply when the filter element on one side needs replacement. The system does not need to stop or halt production during the entire process, thereby improving production continuity.

[0031] Preferably, by connecting the first air outlet 21 and the second air outlet 22 in parallel, two independent air supply paths are formed. When one air outlet is unavailable, the other air outlet can immediately take over the air supply task, ensuring the continuous operation of the cleanroom system. The parallel structure of the first air outlet 21 and the second air outlet 22 allows for switching of air supply channels during operation without stopping the system, enabling filter replacement or maintenance, ensuring production continuity, and is particularly suitable for clean environments that operate 24 hours a day without interruption.

[0032] In this embodiment, the end of the first air outlet 21 is connected to a first air supply box 51 installed on the ceiling of the cleanroom, and the first filter element 511 is disposed inside the first air supply box 51; correspondingly, the end of the second air outlet 22 is connected to a second air supply box 52, and the second filter element 521 is installed inside the second air supply box 52. The two air supply boxes serve as the final filtration nodes before the air enters the cleanroom, and respectively undertake the functions of installing, fixing, and supplying air to the high-efficiency filter.

[0033] To ensure the stability and reliability of the filter elements during use and to prevent them from shifting or falling off due to wind speed or human operation, a first clamping member 512 is installed inside the first air supply box 51, and a second clamping member 522 is installed inside the second air supply box 52. The clamping members are used to hold and fix their respective filter elements, and to fix or remove the filter elements through a threaded structure, making the installation and maintenance of the filter elements more convenient and quick. Furthermore, by arranging the first filter element 511 and the second filter element 521 in independent first air supply boxes 51 and second air supply boxes 52, localized operations can be performed when replacing any one of the filter elements without affecting the operation of the entire clean air supply system.

[0034] In this embodiment, the duct 1 includes at least a first branch pipe 11 and a second branch pipe 12, which are respectively connected to a first air outlet 21 and a second air outlet 22. The first air outlet 21 is connected to the first branch pipe 11 through a first flexible connecting pipe 61, and the second air outlet 22 is connected to the second branch pipe 12 through a second flexible connecting pipe 62, forming two relatively independent air supply paths with flexible buffering capabilities.

[0035] By setting independent first branch pipe 11 and second branch pipe 12, the airflow of duct 1 can be stably distributed to the two sets of air outlets, enabling the dual-channel air outlets to have independent airflow. Furthermore, the introduction of flexible connecting pipes can effectively reduce the mechanical stress on the connection parts caused by factors such as installation errors, equipment vibration, or temperature expansion, avoiding air leakage, structural deformation, or damage that may be caused by rigid connections, thereby extending the service life of the system.

[0036] Meanwhile, the flexible connecting pipes improve the flexibility and operating space of the first air outlet 21 and the second air outlet 22 during installation, enabling installation and adjustment even in ceiling-mounted or space-constrained environments. The first and second flexible connecting pipes 61 and 62 work together in a dual air supply channel. When the filter element on one side needs replacement or maintenance, the air supply path can be switched via an interlocking electric valve without affecting the normal air supply on the other side. This achieves true non-stop maintenance and efficient operation, further ensuring the continuity and reliability of the cleanroom in critical production scenarios.

[0037] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
