The purpose of this utility model is to design a kind of dust explosion protection resistance and revolves level detector, make it have the characteristics of common level detector, and reaction sensitivity preferably can be arranged, can in being arranged, use rugged environments such as dust, and by external circuit can with the online use of industrial PLC, can accurately send the material level shows signal, can control the start and stop of feed conveying equipment again, reach modern automation production and management expectancy.
According to design proposal provided by the utility model, in erecting frame, utilize bearing to connect transmission shaft, left end at erecting frame connects seal casing, connect detecting plate at its right-hand member, the left end of the transmission shaft micromachine interior with being installed on case is connected, it is characterized in that: erecting frame is made of with the ring flange that is positioned at this cylindrical body outside the cylindrical body of a hollow and the loudspeaker body that is positioned at this cylindrical body left end, and the small end of the left end of cylindrical body and loudspeaker body joins.
Right lateral surface at ring flange is provided with the corrugated projection.Right-hand member at cylindrical body is provided with seal, between the big end of loudspeaker body and seal casinghousing rubber seal is set, and microswitch is installed in seal casinghousing.On the big end end face of loudspeaker body, connect support, micromachine and microswitch are installed on support.Right-hand member at transmission shaft has web member, on this web member detecting plate is installed.
The utility model has the advantages that: adopt the novel designs scheme, make the product reaction more reliable sensitive, long service life, small volume structure is firm, can be applicable to the feed bin of various materials, and can be used for rugged surroundings, and dustproof anti-riot effect is superior.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Embodiment
As shown in Figure 1: level detector is mainly by detecting plate 1, gear train 2, and seal 3, erecting frame 4, rubber seal 5, micromachine 6, microswitch 7, seal casing 8 constitutes, and wherein micromachine 6 and microswitch 7 are formed electrical controls partly.
In erecting frame, utilize bearing to connect transmission shaft 2, left end at erecting frame connects seal casing 8, connect detecting plate 1 at its right-hand member, the left end of transmission shaft 2 is connected with micromachine 7 in being installed on case 8, it is characterized in that: erecting frame is made of with the ring flange 4 that is positioned at these cylindrical body 11 outsides the cylindrical body 11 of a hollow and the loudspeaker body 10 that is positioned at these cylindrical body 11 left ends, and the small end of the left end of cylindrical body 11 and loudspeaker body 10 joins.
Right lateral surface at ring flange 4 is provided with corrugated projection 13.Right-hand member at cylindrical body 11 is provided with seal 3, between the big end of loudspeaker body 10 and seal casinghousing 8 rubber seal 5 is set, and microswitch 7 is installed in seal casinghousing 8.On the big end end face of loudspeaker body 10, connect support 9, micromachine 7 and microswitch 6 are installed on support 9.Right-hand member at transmission shaft 2 has web member 12, and detecting plate 1 is installed on this web member 12.
Wherein detecting plate 1 is used to survey the material position, transmission shaft 2 is used to transmit the revolving force of micromachine 6 to detecting plate 1, reach and transmit the change in displacement of touching microswitch 7 when detecting plate 1 is subjected to resistance, seal 3 is made up of multi-layer sealed part, guarantees that outside dust can not enter the electrical control part in the seal casing 8.Erecting frame is used for level detector is installed on bin wall, and mounting means adopts flange form to install, and makes installation more firm.Better tightness when rubber seal 5 is used to make seal casing 8 to install.Micromachine 6 is used to drive detecting plate 1 rotation.Microswitch 7 is used to start or stop micromachine 6, and sends signal.Seal casing 8 is used to protect electric control system not to be subjected to external environment influence.
This product is mainly used in the effect that shows material charge level position in the feed bin, and need reach dustproof anti-riot purpose.For making product reach designing requirement, part all adopts stainless steel in level detector detecting plate 1 and the gear train, and materials such as duralumin are made, and guarantees the intensity and the serviceable life of mechanical mechanism.Seal casing 8 on the erecting frame adopts high strength ABS material to make, and guarantees that one-piece construction has sufficient intensity, and can use in rugged surroundings.Seal 3 and rubber seal 5 adopt sealings, resistance to ag(e)ing etc. all preferably elastomeric material make, the integral sealing degree can well be guaranteed, serviceable life also can be longer.
The principle of work of this product is, the detecting plate 1 of level detector adopts micromachine 7 through the gear train direct drive mode, adopt the airtight separation measure of multilayer between detecting plate 1 and gear train and the electric control system, isolated fully outside dust enters gear train and electric control system, effectively plays dustproof anti-riot effect.Electric control system adopts microswitch 6 and micromachine 7 controls.After level detector energising work, material is when setting regions is following, and micromachine 6 rotates, and drives transmission shaft 2 and detecting plate 1 rotation, and microswitch 7 is in normally open, sends signal and shows that material is below setting regions in the feed bin.When material arrival setting regions, detecting plate 1 is subjected to the resistance of material, touches microswitch 7 by gear train and is in closure state, and micromachine 6 stops operating, and sends signal simultaneously and shows that material arrives setting regions.Send signal can be directly by external auxiliary reclay and PLC online, the start and stop of control feed conveying equipment.
