Abstract
The utility model provides an automatic dust sampler. When the existing dust sampler is put into use, air is sucked from a filter element by a sucking pump, dust remains on an outer filter membrane, a sampling head is taken out after the sampling is ended, and the filter membrane is taken for detection; and when sampling needs to be carried out in a time-phased manner, the sampling head needs to be disassembled repeatedly for the replacement of the filter membrane, and the operation wastes time and energy and is extremely inconvenient. The automatic dust sampler disclosed by the utility model comprises a holder and a sampling case mounted on the holder, wherein an air inlet pipe which is communicated with the outside of the sampling case is arranged inside the sampling case and is connected with a multi-way pipe which is arranged inside the sampling case and is connected with a group of sampling heads through electromagnetic valves, the sampling heads are connected with sucking pumps, the sucking pumps and the electromagnetic valves are connected with a controller which is connected with a group of operating buttons, and the operating buttons are arranged on a shell of the sampling case. The dust sampler disclosed by the utility model is used for sampling dust in air.
Description
Technical field
The utility model relates to a kind of dust automatic sampler that gathers the dust sample in air.
Background technology
Dust sampler is widely used in the monitoring of hygiene and the evaluation of the departments such as prevention from suffering from the diseases, environmental monitoring, labour protection, safety supervision, military affairs, research and teaching, metallurgy, petrochemical complex, railway, building materials, is exclusively used in to measure in the production team workplace mean dust concentration in the air.
Existing dust sampler adopts the atmosphere in the aspiration pump extraction filter core, dust is rested on the filter membrane of outside, sampling is taken off sampling head after finishing, with the filter membrane detection of taking away, when needs are sampled at times, then need constantly to dismantle sampling head and change filter membrane, operation is wasted time and energy, and is extremely inconvenient.
Summary of the invention
The purpose of this utility model is that the problem for above-mentioned existence provides a kind of dust automatic sampler, does not need frequently to dismantle sampling head when carrying out at times dust sampling and changes filter membrane, and is easy to operate, saves manpower, and can effectively prolong the serviceable life of machine.
Above-mentioned purpose is achieved through the following technical solutions:
The dust automatic sampler, comprise support and rack-mount sampling cabinet, described sampling cabinet the inside is installed and is communicated with the outer draft tube of sampling cabinet, described draft tube connects the many siphunculus that are positioned at the sampler case, described many siphunculus connect one group of sampling head by solenoid valve, and described sampling head connects aspiration pump, described aspiration pump be connected solenoid valve and connect controller, described controller connects one group of action button, and described action button is arranged on the shell of sampling cabinet.
Described dust automatic sampler, described sampling head comprised filter core, and the described filter core of crossing is installed filter membrane outward, and the aperture of described filter membrane is not more than 800nm.
Described dust automatic sampler, described sampling head are no less than 6.
Beneficial effect:
1. the utility model is provided with a plurality of sampling heads, control the open and close of opening, stopping of aspiration pump and solenoid valve according to the condition of controller setting, can arrange by controller and regularly be sampled by different sampling heads, take at times different samples to be used for the otherness of the different period samples of research, once dismantle all sampling heads after sampling is finished and carry out filter membrane replacing, reduced the number of times of dismounting sampling head, prolonged the serviceable life of machine, realize simultaneously unattended duty, labor savings.
2. the utility model is simple in structure, and is easy to use.
Description of drawings:
Fig. 1, structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.
Embodiment 1:
As shown in Figure 1: dust automatic sampler of the present utility model, comprise support 1 and rack-mount sampling cabinet 2, described sampling cabinet the inside is installed and is communicated with the outer draft tube 3 of sampling cabinet, described draft tube connects the many siphunculus 4 that are positioned at the sampler case, described many siphunculus connect one group of sampling head by solenoid valve 5, described sampling head connects aspiration pump 6, described aspiration pump be connected solenoid valve and connect controller 7, described controller connects one group of action button 8, and described action button is arranged on the shell of sampling cabinet.
Embodiment 2:
Described dust automatic sampler, described sampling head comprised filter core 9, and the described filter core of crossing is installed filter membrane 10 outward, and the aperture of described filter membrane is not more than 800nm.
Embodiment 3:
Described dust automatic sampler, described sampling head are no less than 6.
Using method:
In the time of need to taking at times different samples, set by controller that the interval certain hour is opened aspiration pump corresponding to single sampling head in turn and solenoid valve is taken a sample, open the sampling cabinet after sampling is finished, take out all filter membranes and detect.
By above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.Unaccomplished matter of the present utility model belongs to those skilled in the art's common practise.
