Abstract
The utility model relates to a filtering protective cover of a stored grain humidity sensor, which is mainly and technically characterized by comprising a sintering tube filtering body, a sealing rubber mat and a waterproof screw, wherein one end of the sintering tube filtering body is airtightly connected with one end of the waterproof screw through the sealing rubber mat; the humidity sensor is mounted in the sintering tube filtering body; and a lead of the humidity sensor is led out from the other end of the waterproof screw. The filtering protective cover is reasonable in design, a normal humidity detection function is realized, the normal detection precision is guaranteed, corrosive gas and other impurities in air are effectively filtered, the humidity sensor is avoided being corroded, a function of protecting the humidity sensor is realized, the filtering protective cover has the characteristic of convenience in mounting and detachment, and the operating cost is saved.
Description
Technical field
The utility model belongs to field, grain storage storehouse, and especially a kind of grain storage humidity sensor filters protective cover.
Background technology
In the grain storage storehouse, often need carry out the fumigation operation, kill the insect in the grain through the phosphine gas that stifling operation produces to grain storage.Because phosphine gas has very strong corrosive attack to grain storage storehouse humidity inside sensor, phosphine gas is to electronic component, and is especially even more serious to metallic copper corrosivity.In order to prevent that humidity sensor is produced corrosive attack, when carrying out the fumigation operation, a kind of processing mode is that humidity sensor is taken off; The problem of its existence is: the dismounting humidity sensor is inconvenience very; Make troubles to maintenance work, another kind of mode is: adopt Polypropylence Sheet that humidity sensor ground is wrapped up, owing to wrap up not tight; Still be easy to leak out corrosive gas, cause humidity sensor to receive corrosion and damage.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of reasonable in design and can prevent effectively that the grain storage humidity sensor of phosphine gas corrosion from filtering protective cover.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of grain storage humidity sensor filters protective cover; Comprise sintered pipes filtering bodies, seal gasket and waterproof screw; One end of sintered pipes filtering bodies is through airtight the linking together of an end of seal gasket and waterproof screw; Humidity sensor is installed in the sintered pipes filtering bodies, and the humidity sensor lead is drawn from the other end of waterproof screw.
And, be provided with the sintering screen pack in the described sintered pipes filtering bodies.
And described waterproof screw is the PG7 water joint.
The advantage and the good effect of the utility model are:
1, this filter protection cover is installed in humidity sensor in the sintered pipes filtering bodies and through waterproof screw strict seal; Not only realized normal humidity detecting function; Guaranteed normal accuracy of detection; And corrosive gas and other impurity in the filtered air effectively, avoided humidity sensor to be corroded, realized defencive function to humidity sensor.
2, an end of this filter protection cover adopts waterproof screw locking humidity sensor lead, has the characteristics of easy installation and removal, has practiced thrift cost of use.
Description of drawings
Fig. 1 is the structural drawing of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is done further detailed description:
A kind of grain storage humidity sensor filters protective cover; As shown in Figure 1; Comprise sintered pipes filtering bodies 1, seal gasket 4 and waterproof screw 5; One end of sintered pipes filtering bodies is guaranteed waterproof screw and the contact seal of sintered pipes filtering bodies through airtight the linking together of an end of seal gasket and waterproof screw, can prevent etchant gas and escape of impurities effectively.Humidity sensor 2 is installed in the sintered pipes filtering bodies; Humidity sensor lead 6 is drawn from the other end of waterproof screw, and the sintered pipes filtering bodies can be filtered atmosphere, filters the inside and outside Atmospheric Flow of protective cover and reaches the inside and outside wetting balance of filtration protective cover; Be provided with sintering screen pack 3 in the sintered pipes filtering bodies; This sintering screen pack is impurity screening and corrosive gas effectively, and simultaneously, the sintering screen pack can be pulled down and clean to keep filter effect.The waterproof screw adopts the PG7 water joint; The clamp jaw of humidity sensor lead through inside is fixed on the screw body and draws with p-wire from the head of waterproof screw and be connected, and the humidity sensor lead makes humidity sensor and extraneous strict seal fix through the waterproof screw after fixing.
It is emphasized that; The described embodiment of the utility model is illustrative; Rather than it is determinate; Therefore the utility model is not limited to the embodiment described in the embodiment, every by those skilled in the art according to other embodiments that the technical scheme of the utility model draws, belong to the scope of the utility model protection equally.
