The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
Embodiment mono-
A workshop air cleaner, comprises upper cover plate 1 and lower cover 3, between upper cover plate 1 and lower cover 3, is threaded connection, and because lower cover 3 has a cavity, so after both connections, between upper cover plate 1 and lower cover 3, forms cavity.On upper cover plate 1, offer gas outlet 2, offer air inlet 4 on lower cover 3, wherein air inlet 4 can evenly arrange along lower cover 3 end faces a plurality ofly, improves the efficiency that gas enters inlet plenum.On upper cover plate 1, be connected with filter core, why described filter core preferably drum shape filter core 5, select cylindrical shape filter core 5, and its object is to expand the contact area of air and cylindrical shape filter core 5, improves the filter efficiency of cylindrical shape filter core 5.The bottom of this cylindrical shape filter core 5 is spherical shape, rather than plane, and object is to increase the contact area of cylindrical shape filter core 5 and air.Described cylindrical shape filter core 5 is divided into two the cavity between upper cover plate 1 and lower cover 3, i.e. inlet plenum and discharge chamber, and inlet plenum is communicated with air inlet 4, and discharge chamber is communicated with gas outlet 2.In order further to improve the contact area of air and cylindrical shape filter core 5, cylindrical shape filter core 5 can be provided with pleated structure, and described pleated structure evenly arranges along the external cylindrical surface of cylindrical shape filter core 5.For convenient dust or the foreign material of removing in filter, except the upper cover plate 1 and lower cover 3 that can be threaded by dismounting fast, also cinder-discharging port 6 can be set on lower cover 3, this cinder-discharging port can be arranged on lower cover 3 end faces or the face of cylinder, and particular location is determined according to the installation situation of filter.When filter is normally worked, this cinder-discharging port 6 is normally closed, while only having the dust known in filter or foreign material, opens the valve of cinder-discharging port 6, and dust or foreign material are discharged from cinder-discharging port 6.Air inlet 4 ends also can arrange section, after air is inhaled into air inlet 4 under suction function, under the effect of section, do composite rotating motion, can move along filter axis on the one hand, on the other hand also can be along filter circumferential movement, the air rotatablely moving collides filter interior and falls in filter in filter.
Filter core adopts interior, domestic and abroad three layer filtration layer structure, and internal layer filter course is active carbon layer 5-3, peculiar smell and toxic gas that this active carbon layer 5-3 exists for absorbed air, and this toxic gas is mainly NH
3, CO
