Abstract
The invention relates to a material level detecting mechanism. The lever principle is adopted in the mechanism; a lever stretches from the outer wall of a pre-steaming tank to the inside of the pre-steaming tank; while reaching a set material level, the lever is pressed by a wood chip to move downwards; the tank wall end of the lever moves downwards; the other end of the lever raises up to trigger a detection sensor; when reaching an empty material level, the lever restores to the original position; and the detection sensor is reset in place. Such mechanisms are installed at higher and lower positions respectively, thereby sensing the height of the material level inside a steaming tank and controlling the time that the wood chip stays inside the pre-steaming tank.
Description
Technical field
The present invention relates to a kind of material-height exploring mechanism, be applied to large granular materials material-height exploring field in non-closed container, the particularly detection of non-regular material.
Background technology
The preparatory boiling cylinder of the grinding machine effect of wood industry industry is that wood chip gets in the cylinder that is full of steam and carries out preparatory boiling, and softening wood chip helps the grinding of wood chip.It is a ultrasonic detector to be set at the cylinder top survey that the material level of boiling cylinder detects classic method.Because be full of steam in the cylinder, there is condensate water on the ultrasonic detector surface, causes sound wave accurately not send and make detection lose efficacy.In order accurately to survey material level in the preparatory boiling cylinder, the lever Detection Techniques have been adopted.
Summary of the invention
The present invention is directed to the prior art deficiency, a kind of material-height exploring mechanism that can accurately detect controlling level in the preparatory boiling cylinder is provided.
The present invention realizes through following technical scheme:
A kind of material-height exploring mechanism comprises cylinder body, and said cylinder body comprises casing wall; This material-height exploring mechanism also comprises adjustable support and leverage; The adjustable support fixing horizontal is arranged on the casing wall, and leverage comprises lever, fulcrum support, and lever is arranged on the adjustable support top through the fulcrum support; Said cylinder body is offered exploration hole, and lever one end stretches into exploration hole, and lever other end horizontal level top is provided with sensor.
Said lever is circular stainless steel circle bar; Said fulcrum support is the bearing location.
Also be provided with the lever guide groove on the said fulcrum support, this lever guide groove is positioned at the long side of lever.
Said sensor for no mechanical contact near switch.
Said lever is that circular stainless steel is justified bar, and the exploration hole diameter is justified the bar diameter greater than circular stainless steel, does not reveal being as the criterion with material; Lever stretches into length in the cylinder not being as the criterion by the material compressive strain, and the outer fulcrum support of cylinder is not more than 1:2 apart from casing wall and fulcrum support to the ratio of sensor distance.
Said lever diameter is 6MM, and the exploration hole diameter is 12MM; Lever stretches into and is no more than 2CM in the cylinder, and the fulcrum support outside the cylinder is apart from casing wall 3CM, and the fulcrum support is to sensor distance 25CM.
Beneficial effect of the present invention is:
The application of this material-height exploring mechanism makes that in steam ambient boiling cylinder material-height exploring no longer receives the influence of condensate water to acoustic sounding in advance, guarantee the preparatory digestion time of wood chip relative evenly.
Description of drawings
Fig. 1 is the structural representation of material-height exploring of the present invention mechanism.
Wherein: 1, wood chip; 2, casing wall; 3, the fulcrum support; 4, lever; 5, the lever guide groove; 6, sensor; 7, adjustable support; 8, exploration hole; 9, pulse spraying equipment.
Embodiment
Below in conjunction with embodiment the present invention is further specified: with reference to accompanying drawing.
The present invention carries out material-height exploring in the unsealed container that steam arranged, it is mobile from top to down requiring material simultaneously.
The said adjustable support 7 of material-height exploring mechanism is fixed on preparatory boiling cylinder outer wall, is used for adjustment (adjusting) lever 4 and aims at exploration hole 8.For lever moves flexibly, said fulcrum frame is to use the bearing location, makes lever guide groove 5 at fulcrum frame postmedian, and lever guide groove 5 width are avoided because the swing of lever rear portion influences proximity transducer 6 actions than the big 1mm of lever.
When expiring material level, along with the use of wood chip 1, wood chip is pushed down lever and is moved down, and lever head makes progress to lower tail, and afterbody touches sensor 6, and confirming has material this moment; When wood chip is lower than lever, lever is return under the effect of gravity, and afterbody leaves sensor 6, explains not have material this moment.
Simultaneously, material-height exploring mechanism can leave the exploration hole 8 that diameter is 12mm at preparatory high and low two positions of boiling casing wall as requested, and exploration hole can not be excessive, avoids granule materials from the hole, to flow out or stops up; Adjustable support is welded on the casing wall, regulates the stainless steel lever through tunable arrangement and is in when the horizontality in the middle of the exploration hole; Require lever to stretch into and be no more than 2CM in the cylinder, the outer pivot distance casing wall 3CM of cylinder, fulcrum is to sensor side 25CM; For the flexible action of lever, require to use pulse spraying equipment to utilize the pulse of compressed air cleaning to exploration hole at exploration hole.
