Description

(54) Noenlel dough consistency sensor

The invention has provided a device for continuous monitoring and control of oeata, for example, brick.

The quality of tehllarakyoh products is a significant mill predetermined by the correct konzlstenoiou tehllarskeho oset, which can still be adjusted to a certain mill * in the press eg. by steaming or adding water.

So far, checking the consistency of the brick road is most often done subjective (by pressing your finger into the band coming out of the press), or by means of so-called. Kabus apparatus (pushed roller). These spdeoby are discontinuous and such a regulation of lukewarms has two people.

It is an amy way of checking the suitability of a path based on sensing its electrical conductivity. In this way it is possible to regulate the predominant humidity of the oesta. Also known are methods based on sensing the pressure at the mouth of the press, the motor load and the mechoic stress of the shaft press.

The abundance of known methods and, in particular, for checking the suitability of the oesta is that they help to maintain a constant value of only one parameter on which the oeata consoles depend. For example, the humidity sensor only responds to moisture change, but due to a change in the composition of the feedstock, the moisture sensor may ddjst *, which does not register the moisture sensor and does not adjust the humidity control circuit * to maintain a consistent consistency even with the raw material composition. .

As far as the regulation is based on the only current of the Usu motor current, this is less sensitive and it is necessary to scan another parameter to increase the sensitivity of the regulator.

Utilization of shaft axial shaft loading * S is not technically solved with a screw press.

These drawbacks are overcome by the Consistenois sensor according to the invention, which is based on sensing the meohanlocal stress of the picking member of the beam inserted into the jet stream so that the non-zero component of the velocity of the flowing substance is perpendicular to the beam.

In a special case, the beam may be just perpendicular to the flow direction of the measured substance.

An exemplary embodiment of the invention is shown in the accompanying drawing. The sensor consists of a probe, 1, a measuring plate body 2, a measuring plate 4, a strain gauge 2 and a housing and a flange 6.

The replaceable round bar shaped probe 1 is terminated by a cylindrical recess at one end. By sliding the probe 1 onto the cylindrical tip of the measuring insert body 2. ⁸⁸ this is firmly connected by means of the Z-pin and the measuring insert body 2. ·

The platelet body 2, together with the platelet 4, is inserted into the housing and the flange 6 and fused by the bolt 2 against removal. Strain gauges 2 are glued to both sides of the measuring plate 2. One along the animalan deformaole, the other across the thermal companza.

The entire sensor is fastened to the wall of the screw press chamber 8 by means of the housing flange 6.

The device according to the invention flows as follows: The probe probe is inserted through the side hole into the screw press chamber at the point where the screws are broken, at the position of the annular position. Using the aa attachment, the entire sensor is fixed to the wall of the press so that the flow direction is perpendicular to the surface of the gauge plate. The moment of the forces exerted by the current oeato on the probe and transmits to the memoral plate which is thereby bent. The plate deformation is scanned by a strain gauge. The second strain gauge serves for temperature compensation. They are connected to the strain gauge bridge. At the elastic intermediate of the gauge plate material, the deformation thereof is proportional to the moment of force applied to the probe. Thus, the more consistent the response, the greater the electrical signal at the strain gauge bridge output. This signal can be used by the steam or humidification regulator. Thus, the sensor allows automatic regulation of the accuracy of the oesta console.

The advantage of the transducer according to the invention is that: a / on the stressed part - futile plate and strain gauges It is out of the press, sleeve-shaped, which makes it convenient to attach the strain gauges to the bridge and keep the ioh prague-friendly conditions, after wear, Hebko can be removed *, o / both, the sensor and its mounting in the press is easy to read, so its replacement does not take * more than 5 minutes, d / at the same time serves as a counterweight, so its use does not require any intervention into jeatvujúoioh llaov. -
