[Detailed description of the device]

[0001]

[Field of Industrial Application] The present invention is an automatic sampling system for precisely controlling the product quality of powders and for giving instructions for product quality adjustments through quality checks during the manufacturing process. It was equipped with a powder adhesion and blockage prevention mechanism, which is used to supply the powder to both when the two analyzers are normal and to supply only to the normal one if one of them is abnormal. The present invention relates to an automatic powder halving device.

2. Description of the Related Art Conventionally, when the same powder (eg, coal ash) automatically sampled from an air flow pipe is analyzed by a plurality of analyzers (eg, ignition loss measuring device, particle size distribution measuring device, etc.) In this method, the edge is cut once, and the powder sample is manually divided using a dichotomer and supplied to the analyzer. The above-mentioned dichotomer is configured by arranging a large number of partition plates in the longitudinal direction at the same intervals to form a large number of grooves, and alternately allocating these grooves to the left and right chutes. The sampling method used is JIS
Known as M 8811. The manual division work in the above-mentioned conventional method is time-consuming, cannot efficiently divide a large number of powders, and the same work is required even if one of the analyzers is out of order, which is efficient. This method cannot be said to be a simple method, and since many analyzes cannot be performed, there is a disadvantage that the measurement accuracy cannot be improved.

In order to solve the above points, the present applicant has
A vibrating powder feeder equipped with a powder inlet at the upper end of one end and a powder outlet at the lower end of the other end is connected to this powder outlet, and a large number of partition plates are arranged in the longitudinal direction at the same interval to provide a large number of partition plates. A divisor configured to form grooves and alternately distribute these grooves to the left and right chutes, and an automatic distributor connected to each of these chutes for feeding powder to an analyzer or a waste tank. Developed a powder automatic two-division device equipped with
We have already filed a utility model registration application (Actual Kaihei 4-3464)
No. 8).

However, in the powder automatic halving device described in Japanese Utility Model Laid-Open No. 4-34648, the bisector is not integrated with the vibrating powder feeding device.
In many cases, the powder adhered to the inside of the dichotomer and the inside of the dichotomizer was blocked. Further, there are cases in which the powder conveying chute that interconnects the bisector, the automatic distributor, the analyzer, and the waste tank, the inside of the automatic distributor, etc. are blocked. Also, powder distribution
In the method described in Japanese Utility Model Laid-Open No. 4-34648
In the powder automatic two-part dividing device, the partition plates are installed at equal intervals and
, The powder was distributed at the same position. The present invention has been made in view of the above points, and can accurately and automatically divide a powder into two parts in a short time, and further facilitates integration with a powder automatic sampling device and an analysis device. It is suitable for continuous and unattended powder quality control,
It is another object of the present invention to provide an automatic powder halving device capable of preventing the powder from adhering to and blocking each part.

In this case, it is preferable to provide vibrators on all powder transfer chutes in order to reliably prevent the powder from adhering and blocking.

Further, the analyzer and the automatic distributors 42 and 44 are operated so as to be activated by the failure signals of the analyzers 34 and 36.
And are connected via fault signal controllers 46, 48.
If the analyzer fails, the line of the automatic distributor is switched by the failure signal and the powder is supplied only to the normal one, which helps prevent the blank time in the quality control of the powder, improves the measurement accuracy and saves labor. Greatly contribute to

In the automatic powder dividing device of the present invention,
In order to improve the efficiency of the automatic sampling system, and at the same time improve the measurement accuracy and prevent the powder from adhering and clogging, the automatically sampled powder is automatically divided into two, and two analyzers 34, If 36 is normal, both are supplied, and if either is abnormal, the automatic distributors 42 and 44 are switched to supply only to the normal one. For powder distribution method
