Abstract

The utility model relates to a cleaning apparatus for mirror condensing type dew point meters, which wipes and removes stains on the dew mirror of a mirror condensing type dew point meter. The cleaning apparatus for mirror condensing type dew point meter is mainly composed of a miniature motor and a brush body driven by the motor; the front end of the brush body has a brush skin which is intermittently and mutually contacted with the dew mirror to finish the stain removing work. The device has simple structure and reasonable arrangement.

Description

Cleaning apparatus for mirror condensing dew point meter

The utility model relates to a kind of sewage disposal apparatus, specifically is the device that is deposited on contamination on the minute surface that is used for removing on the mirror surface condensing dew point hygrometer.

In the mirror surface type dew point hygrometer, minute surface for tested condensation of gas dewfall is the critical component of instrument, no matter how minute surface is placed, because its long-term use, ash in the tested gas will deposit or inevitably attached on the minute surface, and tested gas also must have generation to the corrosion of minute surface, in case this situation occurs, can influence the reflection of photosignal on the one hand, also can occur minute surface simultaneously and Instrument measuring precision be descended because of being corroded.

" external analytical instrumentation techniques and application " (1992 3 phase the 36th～39 page) disclose " exploitation of anti-corrosion type mirror surface condensing dew point hygrometer " literary composition (author: Tian Cunyi) by name, the subject matter that solves in the literary composition is to adopt pure platinum to make the dewfall minute surface, to satisfy the requirement of measuring corrosive gas.The simple corrosion resistant material of using is made minute surface, though can appropriateness slow down minute surface be subjected to degree of corrosion and the anti-corrosion problem of corresponding improvement, adhere to the phenomenon of dust or contamination on the also unresolved minute surface.

The purpose of this utility model is to provide a kind of sewage disposal apparatus, remove deposition or attached to the spot on the minute surface to improve the condition of work of minute surface, improve the serviceable life of minute surface.

The purpose of this utility model is achieved by the following technical solution: the sewage disposal apparatus of mirror surface condensing dew point hygrometer, it comprises a micromachine, the brush body motion that this motor-driven one links with it, the brush skin that the brush body head has soft material to make, this brush skin clearance-type touches on the minute surface, and wipes the spot on the examination removal minute surface.

The utility model compared with prior art, sewage disposal apparatus is newly-designed, it has solved for a long time all adheres on the minute surface or deposits this defective of spot, improved the condition of work of minute surface, minute surface is maintained in the clean condition, and this promptly helps guaranteeing measuring accuracy, has also slowed down the degree of being corroded.

Description of drawings

Fig. 1, Fig. 2 are enforcement structural drawing of the present utility model;

Fig. 3 is the stereographic map of the sewage disposal apparatus among Fig. 1.

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment 1

As seen from Figure 1, be the screw mandrel transmission between brush body (1) and the motor (4), brush body (1) is done the clearance-type translation, and brush body (1) front end is provided with brush skin (1a), and this brush skin (1a) can be made of the chamois leather of quality softness, in order to avoid scratch minute surface (5).Minute surface (5) is positioned at refrigerator compartment, the locular wall of refrigerator compartment (8) is provided with spring (6), its roof pressure a steel ball (7), this steel ball (7) is pressed against in the microscler cylindrical void (1b) on the brush body (1), referring to Fig. 3, can guarantee that like this brush skin (1a) of brush body (1) front end contacts minute surface (5) well.As seen from Figure 3, brush body (1) has a vertically disposed flap (2) near an end of motor (4), have threaded hole (2a) on it, the threads engaged of it and motor (4) axle head, the rotating shaft (4a) of motor (4) just, during backward rotation, flap (2) together advances with brush body (1) or moves back, brush skin (1a) constantly clearance-type is wiped the face (5) of showing on trial, in addition, a limited block (3) in addition that links to each other with brush body (1) and flap (2), with a steady arm (9) in addition of this limited block (3) cooperating, both constitute the work of position-limit mechanism with control motor (4).Referring to Fig. 1, the setting of sewage disposal apparatus should not influence the pressure and the flow of the tested gas in the refrigerator compartment, therefore, can add a seal closure (10) around sewage disposal apparatus.

Embodiment 2

Among Fig. 2, the rotating shaft (4a) of motor (4) and brush body (1) be positioned at perpendicular to the direction of minute surface (5) and with minute surface (5) arranged off-centre, to can not influence minute surface condensation and dewfall forward and backward reflection or scattering like this to light signal, the brush skin (1a) of brush body (1) end is vertical mutually with brush body (1), so just, make brush skin (1a) and minute surface keep the excellent contact state, the rotating shaft (4a) of motor (4) is connected as a single entity with brush body (1), when motor (4) is worked, brush skin (1a) movement therewith, the decontamination of clearance-type ground contact minute surface.The rotating shaft (4a) of motor (4) or brush body (1) add seal (11) with locular wall (8) place of passing through of refrigerator compartment, to avoid tested gas from slit outflow therebetween.

In the

above embodiments

1,2, whole sewage disposal apparatus also can be arranged in the refrigerator compartment, at this moment no longer needs to add to have sealed.

In Fig. 1 and Fig. 2, adopt thread connection between minute surface (5) and its minute surface seat, when minute surface because of damaging or during corrosion, being convenient to change, also can conveniently regulate with brush body (1) and brush mutual height between the skin (1a).
