The purpose of this utility model is achieved through the following technical solutions: this case chamber air intake purifier comprises seal cover and device case, be arranged on the filter unit in device case and the seal cover and be connected device case and seal cover advances, the exit and and the filter unit air intake that constitutes gas channel take over and the air-out interface, filter unit is made up of prefilter and high efficiency particulate air filter two-stage, be tubular construction, two-stage filter is installed in series on same axis, be provided with the stop lead ring between the two, form the circular passage between two filter peripheries and device case and the seal cover, the seal cover that has handle and air inlet is arranged on prefilter one end, be connected with the prefilter end cap, set taper air intake is taken over and directly is plugged on the prefilter inner chamber on the seal cover, form radial seal, the air-out interface is communicated with the high efficiency particulate air filter inner chamber by engage thread, forms end face seal.
In this utility model, device is divided into two sections, pre-filtering section and high efficiency filter section, and the pre-filtering section is made up of prefilter and seal cover, and the high efficiency filter section is made up of high efficiency particulate air filter and device case.The device case of the seal cover of prefilter and efficient section constitutes the external seal interface of purifier jointly; Prefilter and high efficiency particulate air filter are installed on the same axis, are provided with the stop lead ring in two filter junctions.Airflow direction is: need to handle gas and axially enter the prefilter inner chamber through device seal cover air inlet, radially discharge by prefilter through filter element then, enter seal cover and device case annular space, earlier along the annular space axial flow, and then radially enter high efficiency particulate air filter, through the high efficiency particulate air filter filter element along the filter lumen shaft to entering efficient section exhaust port.
In this utility model, ring-shaped groove is set on the device case, change with " bag goes out " that realizes high efficiency particulate air filter, effectively prevent secondary pollution.
Air-out interface and high efficiency particulate air filter connecting portion are provided with the O RunddichtringO, have both guaranteed sealing effectiveness, do not influence again to change high efficiency particulate air filter easily.
The main feature of this purifier:
1, the purifier profile adopts cylindrical structural, and the ancillary filter device is a circular filter; The configuration of employing double-filtration, two-stage filter is installed in series on same axis, the first order is a prefilter, the air intake direction is radially air-out of air inlet through hollow shaft, the second level is high efficiency particulate air filter, and the air intake direction is the radially axial air-out of air intake, and this configuration has made full use of the characteristics of circular filter turnover wind direction, and make up novel structure cleverly; First order configuration prefilter can effectively prolong the service life of second level high efficiency particulate air filter, and second level high efficiency particulate air filter can effectively guarantee to enter the radioaerosol of the air quality of seal box chamber or seal box chamber can be not excessive.
2, filter is installed, changes safe and efficient, and the replacing of two-stage filter is independent of each other.The prefilter mounting means adopts succinct radial seal reliably, directly is installed in the adapter at purifier seal cover top (this part have patent), by the fresh air inlet realization air intake at seal cover top; Change prefilter and only need take off the purifier seal cover, can operate, efficient section function that can countermeasure set, safe and reliable; High efficiency particulate air filter one end is provided with hickey, adopt thread connecting mode with the purifier housing, the sealing of O type circle, it is convenient to change, sealing is reliable, only need take off the seal cover (prefilter is removed with seal cover) of purifier when changing high efficiency particulate air filter, take out the stop lead ring again, can operate.
3, purifier shell nozzle place is provided with ring-shaped groove to realize " bag goes out " replacing of high efficiency particulate air filter, effectively prevents secondary pollution.
4, the stop lead ring being set between prefilter and high efficiency particulate air filter gets loose to prevent prefilter, cut off prefilter and high efficiency particulate air filter simultaneously the slit of posterior axis direction is installed, effectively reduce the internal gas flow disturbance, the characteristics of two-stage circular filter turnover wind direction have been made full use of, rationalization airflow direction, reduce the purifier resistance.
Advantage of the present utility model is: air intake purifier volume is little, and filter is changed safety, quick, reliable, can effectively satisfy the requirement of seal box chamber air inlet system, thereby ensures case chamber interior and surrounding working environment and staff's safety.
