Description

Technical Field

[0001] The utility model relates to the technical field of air filtration, in particular to an air-conditioning ventilation filter duct. Background Art

[0002] The ventilation of early buildings mainly relied on natural ventilation to achieve indoor and outdoor air exchange. With the development of the industrial revolution and the expansion of building scale, people's demand for indoor air quality and temperature control increased, and mechanical ventilation systems began to appear. Early ventilation ducts were mainly simple metal pipes used to introduce fresh air from outdoors into the room or to discharge indoor polluted air. These pipes had a simple structure and a single function, and usually only served to transport air. In order to improve the working environment of workers, some simple ventilation ducts were installed to remove smoke and heat generated during the production process. As people's attention to air quality continued to increase, filtration technology began to be introduced into ventilation duct systems, and activated carbon filtration technology appeared and was applied to ventilation ducts. Activated carbon has a huge specific surface area and can adsorb harmful gases in the air, so that ventilation ducts can not only regulate the temperature and humidity of indoor air, but also purify the air to a certain extent.

[0003] In the prior art, air is filtered through a frame, an activated carbon filter, a sealing material, and a shell. When air passes through the activated carbon filter, pollutants in the air are adsorbed onto the surface of the activated carbon. The activated carbon has a highly developed pore structure and can provide a large surface area, thereby increasing the chance of adsorption. As the air continues to pass through the filter, the pore structure of the activated carbon can block and capture tiny particles in the air, thereby filtering and purifying the air. However, the adsorption capacity of the activated carbon is limited and the pores of the activated carbon are easily clogged by impurities, causing the filtration effect to gradually deteriorate. Therefore, the filter element needs to be replaced regularly or the activated carbon needs to be regenerated. If it is not replaced in time, not only will the expected filtration effect not be achieved, but the previously adsorbed pollutants may even be released again, causing secondary pollution. In addition, the adsorption capacity of activated carbon for different gases varies. It mainly has a good adsorption effect on organic matter, odors and some gaseous pollutants, but has limited removal effect on some inorganic pollutants and cannot fully meet the needs of deep air purification. Therefore, multi-layer filtration of the air and convenient disassembly of the filtration mechanism have become key issues. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides an air-conditioning ventilation filter duct, which aims to improve the problem in the existing technology that the adsorption capacity of activated carbon is limited and the pores of activated carbon are easily clogged by impurities, resulting in the gradual deterioration of the filtering effect.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an air-conditioning ventilation filter duct, comprising a filter port, the bottom end of the inner wall of the filter port is fixedly connected to a collection box, the middle part of the top end of the filter port is slidably connected to a graphite plate, the top end of the graphite plate is fixedly connected to a fixed block, the top end of the fixed block is fixedly connected to an elongated block, the top end of the elongated block is fixedly connected to a fixed plate, the right side of the bottom end of the fixed block is fixedly connected to a filter screen, the top end of the filter port is fixedly connected to a plurality of baffles, the right side of the baffle is fixedly connected to a telescopic rod, the right end of the telescopic rod is fixedly connected to a sealing block, and a shock-absorbing mechanism is provided on the outside of the filter port, and the shock-absorbing mechanism is used to reduce vibration of the device.

[0006] As a further description of the above technical solution:

[0007] The shock-absorbing mechanism includes a rubber plate, the bottom end of the filter port is fixedly connected to the top end of the rubber plate, the bottom end of the rubber plate is fixedly connected to a support plate, the rear side of the top end of the support plate is fixedly connected to a hollow column, the interior of the hollow column is fixedly connected to a spring, the rear end of the spring is fixedly connected to a solid column, and the rear end of the solid column is fixedly connected to the front end of the U-shaped plate.

[0008] As a further description of the above technical solution:

[0009] The right side of the filter port is fixedly connected with a connecting ring 1, and the right side of the connecting ring 1 is fixedly connected with an air intake pipe.

[0010] As a further description of the above technical solution:

[0011] The right side of the air inlet pipe is fixedly connected with a fixing ring, and the left side of the filter port is fixedly connected with a second connecting ring.

[0012] As a further description of the above technical solution:

[0013] The left side of the connecting ring 2 is fixedly connected with an air outlet pipe, and the top end of the air inlet pipe is fixedly connected with a mark.

[0014] As a further description of the above technical solution:

[0015] A hole is provided on the right side of the fixing ring, and a silencer plate is fixedly connected to the inner wall of the air intake pipe.

[0016] As a further description of the above technical solution:

[0017] The bottom end of the sealing block is slidably connected to the top end of the filter port, and the outer side of the fixing block is slidably connected to the inner side of the filter port.

[0019] The front and rear sides of the graphite plate are slidably connected to the inner wall of the filter port, and the bottom end of the graphite plate is fixedly connected to the bottom end of the inner wall of the collection box.

[0020] The utility model has the following beneficial effects:

[0021] 1. In the present invention, after the air is sucked in by the intake pipe, the air enters along the filter port, first passes through the filter screen to remove large particles of impurities, and then the air contacts the graphite plate for secondary filtration. The graphite plate and the filter screen need to be cleaned or replaced after a period of use. At this time, the fixed block can be pulled outward by contracting the telescopic rod, and the filter mechanism can be pulled out of the filter port and maintained, realizing multi-layer filtration of the air and disassembly and assembly of the filter device, preventing the absorption capacity of the graphite plate 4 from being saturated due to long-term use and being unable to filter the air again.

[0022] 2. In the utility model, the device will generate vibration and noise when working. Placing the filter port on the rubber plate can reduce the vertical vibration. The horizontal vibration pushes the solid column into the hollow column, compressing the spring, and converting the vibration energy into the elastic force of the spring, thereby offsetting the horizontal vibration. This can achieve buffering of the device and prevent the excessive vibration intensity of the device from causing excessive noise and affecting the working conditions of surrounding staff.
