Abstract
The utility model relates to a detection device, in particular to a detection device for air filter screens. The dust detection device for the air filter screens comprises a dust deposition amount detection device and an alarm control box, wherein the dust deposition amount detection device comprises a box body, three layers of filter screens are arranged in the box body, and the first layer of filter screen and the third layer of filter screen are provided with electrode sockets; and a detection circuit is arranged in the alarm control box and comprises a CPU (central processing unit). The signal input end of the CPU is provided with a reset detection button, a mute button and a detection port, and the signal output end of the CPU is provided with an operation detection lamp, an alarm lamp and an alarming apparatus. The detection port is connected with the electrode sockets. The detection device directly detects dust deposition amount on the filter screens, so the detection device can effectively and precisely judge the dust deposition amount on the filter screens so as not to give a false alarm, thereby being convenient for use.
Description
Technical field
The utility model relates to a kind of pick-up unit, relates in particular to a kind of airstrainer pick-up unit.
Background technology
At present, known airstrainer dust deposit amount is with range estimation or adopt dust sensor, and prior art is mainly utilized the photoelectric sensing effect, but it is second-rate and situation that airstrainer is comparatively clean is easy to generate false alarm to get rid of outside air; The dust sensor volume is too huge simultaneously, is difficult for being placed in the airstrainer.Dust sensor non-stop run in 24 hours must bring the wasting of resources, and the field of employment also is restricted.
Summary of the invention
In order to address the above problem, the utility model provide a kind of simple in structure, can be placed in the small device of space and the airstrainer detecting device of false alarm can not occur.
To achieve these goals, the utility model is mainly solved by the following technical programs: a kind of airstrainer dust detection, it is characterized in that, comprise dust deposit amount detecting device and controlling alarm box, described dust lamination amount detecting device comprises box body, be provided with the three layer filtration net in the box body, ground floor screen pack and three layer filtration net are equipped with electrode socket; Be provided with testing circuit in the described controlling alarm box, testing circuit comprises CPU, the signal input part of described CPU is respectively equipped with reset detection button, mute button and detection port, the signal output part of described CPU is respectively equipped with operation and detects lamp, alarm lamp and warning horn, and described detection port is connected with described electrode socket.
The utility model judges by the dust deposit amount on the direct detection screen pack, judges the dust deposit amount on the screen pack effectively, accurately and false alarm can not occur, made things convenient for use.

Embodiment
Below in conjunction with accompanying drawing 1-5, the embodiment of the technical solution of the utility model is described in further detail.
Embodiment: a kind of airstrainer dust detection comprises dust deposit amount detecting device 1 and controlling alarm box 2.
Dust lamination amount detecting device 1 comprises the box body 3 that plays the insulation fixation, is provided with the three layer filtration net in the box body 3, and ground floor screen pack 4 and three layer filtration net 6 are for the stainless steel screen pack and be equipped with electrode socket 7; Middle layer screen pack 5 is the insulation screen pack.
Be provided with testing circuit 8 in the controlling alarm box 2, testing circuit 8 comprises CPU9, described CPU9 signal input part is respectively equipped with reset detection button 10, mute button 11 and detection port 12, the signal output part of described CPU9 is respectively equipped with operation and detects lamp 13, alarm lamp 14 and warning horn 15, and described detection port 12 is connected with described electrode socket 7.
As shown in Figure 5, after the airstrainer dust detection was opened, CPU9 can detect screen pack dust deposit amount.When airstrainer was clean, operation detected lamp 13 and is shown as green light.When airstrainer is dirtier, alarm lamp 14 flickers in the controlling alarm box 2, warning horn 15 is reported to the police simultaneously, and at this moment, if the user presses reset detection button 10, CPU9 can detect again to the screen pack amount of dust.If the user presses mute button 11, alarm lamp 14 flickers this moment, warning horn 15 cuts out.
