Abstract
The automatic level controller belongs to the field of electric engineering technology. It is composed of sensing head and control display circuit. The main characteristic is that the pressure of the material is used as sensing condition, and an elastic sensing cap is used to make it form pressure displacement, and trigger the control circuit to work. A control measure for instantly stopping the feeding equipment is arranged in the control circuit; and a time-base circuit is triggered to execute time delay, and the time delay is stopped after all the inertia storage materials in the operation of the equipment are conveyed into the charging bucket, so that the control measure of frequently starting the feeding equipment is avoided. It is suitable for controlling the position of powder material, granular material and liquid level, and can control various high-temp. materials and chemical liquid with strong corrosivity by changing sensing cap. It is an ideal device for automatically controlling and indicating the material level and the liquid level.
Description
The utility model belongs to the electro-engineering technical field.
At present domestic to granular material, granular material, chemical liquid and water etc., it is general to go back neither one, the material level automatic control of liquid device of dependable performance.
Be well known that the LWK-02 moulding mixture position self-actuated controller of on cement industry, using.Its principle is to utilize solid accumulation height and electrical conductivity size to decide the starting of oscillation of condenser type oscillator and failure of oscillation to realize material level is controlled, because the fluctuation of material material and moisture content is bigger, electrical conductivity is not the same, is difficult to realize reliable control.
The purpose of this utility model is that a kind of device that the ad-hoc location of solid and liquid material is controlled automatically will be provided.
The purpose of this utility model is achieved in that it utilizes the pressure of material to be sensed condition; when material touches the elasticity sensing cap of sensing head; the sensing cap is by sensing position limitation protection head; drive link; the decompression of travel switch is adjusted first pressure signal and is passed to microswitch in the travel switch; the long closure of making war of microswitch; make the sensitive relay upset adhesive in the controller; the equipment component of one tunnel control feeding system front shuts down immediately; another road is triggered 555 time base circuits and is carried out time-delay; delay time till this equipment of stopping of need delaying time all is transported to the inertia storing amount in the middle of oneself running in the batch can; at this moment the material level of batch can has been raised to maximum; simultaneously because regular quantitatively the increasing of charge level; effectively avoided the problem of charging equipment frequent starting; when the next procedure materials drop to charge level to leave the elasticity sensing cap of sensing head; the bounce-back of sensing position limitation protection head rest spring adds elasticity sensing cap self elasticity; each portion mechanism and element are all automatically reset simultaneously; the light emitting diode of control indicating section is given the discharging spacing wave; relay and time-delay part also reset simultaneously; the control feeding system continues material loading, thereby realizes the material level automatic control of liquid level.
The concrete structure of utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is according to the sensing head structural representation that the utility model proposes.
Fig. 2 is control indicating circuit figure of the present utility model.
Describe details and principle of work in detail below in conjunction with Fig. 1 and Fig. 2 according to the concrete device that the utility model proposes.
(1) is elasticity sensing cap; (2) sensing head holder, in have a sensing position limitation protection head (3) to play the pressure transmission and to the effect of excessive pressure position limitation protection, also be in order to ensure the excessive irreducible effect of following the string of the unlikely distortion of elasticity sensing cap simultaneously.(4) be drive link, one is connected with sensing position limitation protection head (3), and the other end is adjusted head (6) with the pressure reducing protection of travel switch (5) lining and is connected, a corrective action to microswitch (7) pressure protect and stroke distances.Between sensing head holder (2) and sensing position limitation protection head (3), to be enclosed within on the drive link be back-moving spring (8), (9) are the flanges that connects sensing head and batch can (10).After sensing pressure, elasticity sensing cap (1) impels sensing position limitation protection head (3) and drive link (4) stressed displacement simultaneously by the elasticity of self at once; adjust head (6) through pressure reducing protection and touch microswitch (7); make the adhesive of control indicating section sensitive relay (11); its long close point (12) discharges; the control charging equipment stops material loading immediately; its other group leader's closed contact (13) also discharges simultaneously; trigger 555 time base circuits (15) through synchronous trigger circuit (14) and carry out time-delay; behind the certain hour of delaying time; the circuit state upset; the time relay (16) adhesive; moving disconnected (normally closed) contact (17) of its delayed start-up disconnects; this charging equipment that stops of need delaying time shuts down, and light emitting diode (18) is to show that the batch can material is full and material is empty.After elasticity sensing cap lost pressure, the duty of all sensing elements and control indicator elment all resetted, and feeding system continues material loading, thereby had realized that effectively the utility model controls the purpose of material level liquid level automatically.
Claims (3)
1, a kind of material level automatic control of liquid device, this device has a control display circuit; (11) be that sensitive relay, (12), (13) are that the long close point of sensitive relay, (15) are that time base circuit, (16) are that timing relay, (17) are moving disconnected (normally closed) contacts of delayed start-up; on its circuit, also follow sensing head microswitch (7); other is made up of known circuits, and feature of the present utility model is to realize material level liquid level control indication by the synchronous triggering delay control circuit (14) of elasticity sensing cap (1), sensing position limitation protection head (3), drive link (4), back-moving spring (8), time base circuit, the full mode circuit (18) of the empty material of indication material.
2, material level automatic control of liquid device according to claim 1, it is characterized in that elasticity sensing cap (1) is thin with rubber, copper, Thin Stainless Steel etc. has resilient material and makes.
3, material level automatic control of liquid device according to claim 1 is characterized in that the shape of elasticity sensing cap (1) is provided with circle, square, rectangle.
