Embodiment 1

[0031] see Figure 1 to Figure 3 As shown, the present embodiment provides a return air filter device for an air-conditioning box, including a box body 101, the box body 101 has an air inlet 106 and an air outlet 107 arranged oppositely, and the inside of the box body 101 is provided with a spray device, The oil mist filter 102 and the oil collector 103, the injection device is located between the air inlet 106 and the oil mist filter 102, and is used to spray cleaning agent to the oil mist filter 102; the section of the oil mist filter 102 is honeycomb; The oil collector 103 is located below the oil mist filter 102 , and the oil collector 103 is detachably connected to the box body 101 .

[0032] Based on this structure, the return air filter device for the air conditioning box provided in this embodiment can effectively purify the oil mist in the return air by setting the oil mist filter 102, and prevent the filter screen in the air conditioning box from being blocked by oil...

Embodiment 2

[0054] see Figure 4 As shown, this embodiment also provides a return air filter device for the air conditioner, the return air filter device for the air conditioner in this embodiment is an improvement on the basis of Embodiment 1, in addition The technical solution of Embodiment 1 also belongs to this embodiment, and will not be described again here. The same components use the same reference numerals as in the first embodiment, and reference is made to the description of the first embodiment.

[0055] In some embodiments, the return air filter device for the air conditioner further includes a pressure sensor 105 and a controller, the pressure sensor 105 is connected to the controller, and the controller is connected to the injection device.

[0056] With the continuous accumulation of oil in the oil mist filter 102, the pressure in the oil mist filter 102 will gradually increase. Automatic cleaning saves manpower and improves efficiency.

[0057] It should be noted that ...

Embodiment 3

[0062] This embodiment provides an air conditioning box, including the return air filter device for the air conditioning box provided in Embodiment 1 of the present invention.

[0063] The air conditioning box provided in this embodiment uses the return air filter device for the air conditioning box provided in Embodiment 1 of the present invention, which can realize the organic combination of air conditioning and oil mist purification, and realize the effective purification of liquid oil mist in the workshop. Prevent the filter in the air conditioning box from being clogged by oil, and ensure the normal operation of the air conditioner.

Abstract

The invention relates to the technical field of air purification of workshops and air conditioners, in particular to a return air filtering device for an air hundling unit and the air hundling unit. The return air filtering device for the air hundling unit comprises a box body which comprises an air inlet and an air outlet which are oppositely arranged, and the box body is internally provided witha spraying device, an oil mist filter and an oil collector; the spraying device is located between the air inlet and the oil mist filter and used for spraying a cleaning agent to the oil mist filter;the cross section of the oil mist filter is in a honeycomb shape; and the oil collector is located on the lower part of the oil mist filter and detachably connected with the box body. According to the return air filtering device for the air hundling unit and the air hundling unit, the oil mist filter is arranged to perform effective purification on oil mist in return air, and filtering screens inthe air hundling unit is prevented from being blocked by oil dirt. Meanwhile, the oil mist filter can be cleaned, oil mist liquid drop which is washed down falls into the oil collector under the action of own gravity, recycling of the oil mist filter can be ensured, and the purifying efficiency is improved. The operation is convenient and rapid, and the working efficiency is high.

Description

technical field [0001] The invention relates to the technical field of air purification and air conditioning in a workshop, in particular to a return air filter device and an air conditioning box for an air conditioning box. Background technique [0002] Bearing processing plants need to use a large amount of engine oil and lubricating oil in the production process, and the oil mist content in the air is extremely high. In order to ensure the quality of the workpiece, there is a high requirement for the indoor ambient temperature, and the air conditioning system needs to be turned on throughout the year. The oil mist in the air has a great impact on the air conditioning system. The filter screen is often clogged due to excessive oil pollution, resulting in a large loss, and it is time-consuming and laborious to replace and clean the filter screen. Contents of the invention [0003] The first object of the present invention is to provide a return air filter device for an a...
