Description

Technical Field

[0001] This utility model relates to the field of filter testing technology, and in particular to a testing device for a plate air filter. Background Technology

[0002] Panel air filters are widely used in industries such as steel, electronics, chemicals, automotive, environmental protection, and power. They are the best intake filtration equipment for centrifugal compressor filter rooms and for pre-filtration of dust and oil in various air conditioning systems. The filter material of this product is composed of synthetic glass fiber. It has a large dust holding capacity and a long service life, and is often used for pre-filtering of air. To ensure the filtration effect of panel air filters, the entire filter is usually tested to improve product quality. When testing panel air filters, a testing device is required to determine whether the panel air filter can effectively filter particles in flue gas. The testing device includes a housing, a smoke generator installed inside the housing, and a smoke outlet installed on the housing. The smoke generated by the smoke generator flows out through the smoke outlet.

[0003] Regarding the aforementioned related technologies, the inventors discovered that when testing panel air filters, the panel air filter is placed above the smoke outlet, with the frame of the panel air filter sealed to the housing. After the smoke passes through the panel air filter, a smoke analyzer is used to test whether the filtered smoke is qualified. After the measurement is completed and the panel air filter is removed, a large amount of unfiltered smoke still flows out of the smoke outlet from inside the housing, polluting the working environment and reducing the effectiveness of use. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a detection device for a plate air filter, which reduces the pollution of the working environment by smoke and improves the effect of use.

[0005] To solve the above-mentioned technical problems, the present invention provides a detection device for a plate-type air filter, comprising: a mounting box and a rectangular baffle frame connected to its top; the top of the mounting box has a rectangular hole, and a rectangular smoke conveyor is sealed inside the rectangular hole; the upper end of the rectangular smoke conveyor extends above the mounting box, and the upper end of the rectangular smoke conveyor is not higher than the upper plane of the rectangular baffle frame; the lower end of the rectangular smoke conveyor is sealed and extends into the interior of the mounting box; a partition is connected to the inner cavity of the upper end of the rectangular smoke conveyor; a smoke outlet hole is provided at the center of the partition; a sealing ring is connected inside the smoke outlet hole; a smoke generator is provided at the bottom of the mounting box; and the smoke outlet of the smoke generator is connected to the rectangular smoke conveyor through a pipe.

[0006] It also includes a rod-shaped plug and a guide sleeve assembly, wherein the rod-shaped plug is slidably connected to the inner cavity of the guide sleeve assembly, and the bottom of the rectangular smoke conveying cylinder is connected to a telescopic drive rod that drives the rod-shaped plug to move axially.

[0007] The rectangular smoke conveyor is connected to a smoke extraction component, which is suitable for extracting the smoke from inside the rectangular smoke conveyor.

[0008] By adopting the above technical solution, during use, an appropriate amount of water is injected into the rectangular water-blocking frame, with the water level below the top of the rectangular smoke conveyor. The plate air filter to be tested is placed above the rectangular smoke conveyor, with the frame of the plate air filter extending into the water and contacting the upper surface of the mounting box. Through the action of the water, a sealed connection is formed between the plate air filter and the mounting box. The smoke generator produces a large amount of smoke, which enters the rectangular smoke conveyor and then flows out through the smoke outlet hole. The smoke then passes through the entire plate air filter. Next, a smoke analyzer is used to detect the filtered smoke and obtain relevant measurement parameters. After the measurement is completed, the telescopic drive rod is operated to drive the rod-shaped plug to slide upward along the inner hole of the guide sleeve assembly. The rod-shaped plug is tightly connected to the sealing ring in the smoke outlet hole, thereby preventing the smoke from drifting upward from the smoke outlet hole. Next, the smoke extraction assembly operates to extract the smoke from the rectangular smoke conveyor and process it uniformly, thereby reducing the impact of the smoke generated by the smoke generator on the working environment, reducing pollution to the working environment, and improving the usage effect.

[0009] In a preferred embodiment, the present invention can be further configured such that the guide sleeve assembly includes a guide sleeve and two fixing blocks symmetrically connected to its outer circle, the outer ends of the fixing blocks being connected to the inner wall of the rectangular smoke conveying cylinder.

[0010] By adopting the above technical solution, the rod-shaped plug is slidably connected inside the guide sleeve, so that the upward-moving rod-shaped plug can smoothly make elastic contact with the sealing ring.

[0011] In a preferred embodiment, the present invention can be further configured such that: the rod-shaped plug includes a round rod and a conical body connected to its upper end; the round rod is slidably connected to the inner hole of the guide sleeve; and the telescopic drive rod operates to cause the conical body on the round rod to be tightly connected to the sealing ring.

[0012] By adopting the above technical solution, after the round rod slides upward a certain distance inside the guide sleeve, the conical body comes into close contact with the sealing ring, thereby achieving the effect of sealing the smoke outlet round hole and preventing the smoke in the rectangular smoke conveying cylinder from drifting into the external environment.

[0013] In a preferred embodiment, the present invention can be further configured as follows: the smoke extraction assembly includes a fan and a one-way valve connected to a rectangular smoke conveying cylinder; the smoke inlet of the fan is connected to the rectangular smoke conveying cylinder via a pipe; the smoke outlet of the fan is connected to a smoke exhaust pipe; a support frame is connected to the side of the rectangular smoke conveying cylinder; and the fan is mounted on the support frame.

[0014] By adopting the above technical solution, the exhaust fan draws the flue gas from the rectangular smoke conveyor, creating a negative pressure state inside the rectangular smoke conveyor. A portion of the air enters the inner cavity of the rectangular smoke conveyor through the one-way valve, causing the air pressure inside and outside the rectangular smoke conveyor to tend to balance. The smoke drawn out by the exhaust fan flows to the outside through the exhaust pipe for unified treatment, reducing pollution to the working environment and enhancing the effectiveness of the detection device.

[0015] In a preferred embodiment, the present invention can be further configured such that: the front of the mounting box is provided with a mounting door, and a door panel is hinged to the side of the mounting door.

[0016] By adopting the above technical solution and using the installation door, the installation and maintenance of the smoke generator and smoke extraction components are facilitated, thus improving the convenience of assembly and maintenance.

[0017] In summary, this utility model has at least one of the following beneficial technical effects:

[0018] After the measurement is completed, the telescopic drive rod works to tightly connect the rod-shaped plug with the sealing ring inside the smoke outlet hole, thereby preventing the smoke from drifting upwards from the smoke outlet hole. The smoke extraction component then extracts the smoke from the rectangular smoke conveying cylinder and processes it uniformly, thereby reducing the impact of the smoke generated by the smoke generator on the working environment, reducing pollution to the working environment, and improving the usage effect.
