Abstract
The utility model relates to a filtering device, and the filtering device is used for box bottom filtering, and especially used for laboratorial detection of box bottom obstruction. The filtering device for laboratorial detection of box bottom obstruction is characterized by including a box body and a filtering device which is arranged on the box body bottom, outer casings are arranged on the four side faces outside the box body, a side vacuum channel is formed between the outer casings and the box body, connecting channels extend from four directions and are in mutual through connection with the filtering device in the middle, a filtering net which is convenient in replacement is arranged, the condition of monitored air inlet flow rate is transferred to a computer system by a sensor, the service life of the filtering net is judged, the filtering device and an exhaust tube which is provided with an easy-to-disassembled filtering net can be sued for more accurate bidirectional detection, and are more effective by combination in practice.
Description
Technical field
The utility model relates to a kind of for bottom half filtration, relates in particular to a kind of filter that detects bottom half obstruction for laboratory.
Background technology
In casing vacuum pouring process, the metal filter screen of casing side especially easily damages.Simultaneously, after long-time use, bottom screen pack easily stops up inefficacy, thereby makes casing in casting process, lose negative pressure effect, and current casing is changed all troubles very of metal filter screen.The casing that making mould in actual use needs wants a lot, often there is the phenomenon of damaging screen pack and can not get changing, have a strong impact on the normal production of streamline, cannot detect again the service life of screen pack, even if complicated with the filter apparatus configuration of former casing, time-consuming again while detecting.
Summary of the invention
The purpose of this utility model is: the deficiency existing for prior art, provides a kind of filter stopping up for laboratory detection bottom half that detects the screen pack life-span.
For realizing the object of the utility model, be achieved by the following technical solutions:
A kind of filter that detects bottom half obstruction for laboratory, comprise the filter that box main body and box main body bottom are provided with, on outer four sides of box main body, be equipped with shell body, between shell body and box main body, form sidepiece vacuum passage, box main body outside in shell body is provided with a plurality of openings with the sidepiece vacuum passage place of interconnecting, sidepiece vacuum passage is all connected with interface channel at the bottom position of main body, interface channel connects with each other with filter in the middle of extending in from four direction, described bottom filter device comprise by set bolt, connect vacuumize pressing plate and metal platen, vacuumize the outside that pressing plate wraps in metal platen, metal platen is provided with hole, the below of metal platen is connected with screen pack, interface channel is provided with exhaust tube, on exhaust tube, be also provided with screen pack, inductor is all housed on screen pack, inductor is connected with external control system, interface channel is connected with described metal platen in bottom.
Compared with prior art, the beneficial effects of the utility model are: the screen pack of being convenient to replacing is housed, recycling inductor is transferred to computer system the situation of monitoring air intake flow, the service life of judgement screen pack, by easily detachable screen pack is housed on filter and exhaust tube, to do two-way detection accuracy higher, is attached in reality and more produces effect.

The specific embodiment
1-5 makes a detailed explanation the specific embodiment of the present utility model with reference to the accompanying drawings below.
A kind of prior-warning device stopping up for laboratory bottom half screen pack, comprise the filter 2 that box main body 1 and box main body 1 bottom are provided with, on outer four sides of box main body 1, be equipped with shell body 3, between shell body 3 and box main body 1, form sidepiece vacuum passage 4, box main body 1 outside and sidepiece vacuum passage 4 places of interconnecting in shell body 3 are provided with a plurality of openings 5, sidepiece vacuum passage 4 is all connected with interface channel 6 at the bottom position of box main body 1, interface channel 6 connects with each other with filter 2 in the middle of extending in from four direction, described bottom filter device 2 comprise by set bolt 7, connect vacuumize pressing plate 8 and metal platen 9, vacuumize the outside that pressing plate 8 wraps in metal platen 9, metal platen 9 is provided with hole, the below of metal platen 9 is connected with screen pack 10, interface channel 6 is provided with exhaust tube 11, on exhaust tube 11, be also provided with screen pack 10, inductor 12 is all housed on screen pack 10, inductor 12 is connected with external control system, interface channel 6 is connected with described metal platen 9 in bottom.
In use, inductor 12 connection computer testing datas on flows are prior art.Exhaust tube 11 connects outer vacuum machine, because suction air flows into by box main body 1 upper opening, one side flows in sidepiece vacuum passage 4 by the opening 5 of the top, one side directly flows into from bottom filter device 2, at the most beneath inflow interface channel 6, by the exhaust tube 11 on interface channel 6, extract out and go.Need to draw according to experimental data the analysis of stopping state, can test generally and how long to change screen pack 10 service time, by the service condition of screen pack on 2 obstructed test filters 2 of inductor 12 and exhaust tube 11, comprehensively judge stopping state separately, simultaneously in the corresponding situation of removing the screen pack 10 on exhaust tube 11.
