Description

AUTOMATED WATER SAMPLE WITH OPEN CANAL PUNCH

It deals with the present patent application for an OPEN DUTCH PUNCHED AUTOMATED WATER SAMPLER especially a simple constructivized automated sampler capable of collecting open channel water samples whose differential is the associated perforated U-tube compressed air which, when properly positioned at the collection point, allows the compressed air to take the sample inside to a container close to the sampler and, likewise, compressed air avoids clogging of the tube as well as constant stops of equipment for maintenance.

FIELD OF APPLICATION The automated water sampler has as its field of application the use in plants, industries, factories, water treatment plants, among others, more specifically designed to be installed after the parshall gutter sensor in sugar and alcohol plants. to measure the amount of sucrose eliminated in the production process, but not limited to it.

CONVENTION

One of the factors that directly impact the billing of a sugar and alcohol plant is the control of sugar loss points that involves the entire production process, having as main sugar loss point the wastewater, which is the sugar cane washing. and cleanings in general.

In order to achieve an effective control of the loss points, chemical analyzes are necessary to quantify the sugar that is being destroyed or wasted in production. For this purpose, it is essential to use the composite collection of the material, which occurs through performing various samples collected over a period of time.

Currently, the water samplers built in the plants, due to the low technology employed, have great difficulty in weighing the sample according to the water flow at the collection point, thus not obtaining representative samples.

On the other hand, more modern systems such as integrated continuous collectors with automated Parshall gutters found in the domestic market for automatic wastewater collection have some drawbacks, namely:> Constant clogging due to vegetation fall in the open channel; > Frequent breaks; > Low quality equipment; > High maintenance index; > Specialized labor; > High cost of labor and spare equipment, among others.

With these difficulties in mind, manufacturers that are more attentive to market needs seek to develop equipment that provides optimum results, constructive simplicity, easy handling and low cost, in accordance with the focus of this privilege request, features that have gained space in the consumer market. .

STATE OF THE ART The present state of the art anticipates some patent documents dealing with the subject matter such as PI0305731-3 AUTOMATIC WASTE WATER SAMPLE COLLECTOR which refers to a remote powered, peristaltic pump automatically eluted by an electronic system, by radio or digital command, battery-powered, eliminating water deposited in the direct flow collection tube, reversing flow by collecting a pre-established amount of water to be examined, which passes through a removable container containing a fiber or membrane filter, suitable for the examination to be performed on waste water collected at that location at any time or in any weather condition.

In this case, the aforementioned patent discloses as inventive concept an electronic sample collector with removable collector that by means of pump initiates the flow that passes through the removable container with filter or membrane inside, which after collection, removes the container and the filter or membrane is preserved with a chemical and by envelope is taken to the laboratory. It is observed that in the figure of the document the equipment is complex constructively, with electronic components, snap-in clips, all of which favors constant maintenance, installation and maintenance must be done by specialized people, labor and high cost components. , as well as sterilization and other indispensable factors for the optimal functioning of the sample collection, such as the envelope and the chemical that add up to the use of the process.

NEW PRODUCT

Aware of the state of the art, its shortcomings and limitations, the inventor, after studies and research, has created the AUTOMATED OPENED PIPE WATER SAMPLE in question, which in general conceives an automated sampler of simple constructivity, capable of collecting samples. open channel water, whose differential is the perforated “U” tube associated with the compressed air which, properly positioned the tube at the collection site, allows the compressed air to take the sample contained inside to a container near the sampler and Likewise, compressed air prevents clogging of the pipe as well as constant downtime of maintenance equipment.

The AUTOMATED OPEN CANAL PUNCHED WATER SAMPLER aims to develop a continuous sampler for the sampling of wastewater in sugar and alcohol plants that will be based on the charge and discharge laws in a capillary tube (Poiseuille and Bernoulli). with advantages such as low cost, low maintenance and can be built by plant technicians and engineers, but at the same time also have all the necessary automation requirements to ensure sample representativeness.

The AUTOMATED OPENED PIPED WATER WATER SAMPLER aims to make sampling practical without clogging the water inlets, its operation is simple and allows a water exclusion procedure to be performed prior to collection. from the last sample all to increase and guarantee a genuine sample. AUTOMATED OPEN CANAL PUNCHED WATER SAMPLER has PLC-controlled sensors to identify the presence of the collected material vial and another to identify the sampled liquid level, while once the container is full, the sensor will charge. and interrupts the sampler operation.

BENEFITS

In short, the claimed sampler has the most important advantages:> Allows sampling to be collected without clogging; > Avoid lack of sample for analysis; > It has constructive simplicity; > Guarantees maintenance and assembly without specialized labor; > Low production cost; > Easy handling; > Great cost-benefit ratio; > Optionally promotes direct sample weighting without integration with flowmeter. In the following, the invention is explained with reference to the accompanying drawings, in which they are shown by way of illustration and not limitation: Fig. 1 - Schematic view of the automated open channel perforated pipe water sampler;

Fig. 2 - Representative view of the automated open channel drilled water sampler installed after the parshall rail sensor. DETAILED DESCRIPTION The AUTOMATED OPEN DUTCH PIPED WATER SAMPLE, the subject of this patent application, refers to an automated sampler (1) that is easy to install and simple to construct, initially comprised of an air compressor (2). ) connected to a tube (3) and this in turn to the pneumatic spring return valve (4) responsible for collecting sample material. The first use of the sampler (1) should depend on the activation of the screen (14) when the sampling should be performed automatically. The U-shaped perforated tube (5) has several holes (6) in its length and the portion of the sampler (1) which remains submerged in the channel through which the liquid to be sampled passes, such that water enters through the holes (6) filling the perforated tube (5) to the water level of the channel (principle of the communicating vessels) after the air compressor (2) is activated and with the opening of the pneumatic valve (4) releases a jet of air tablet capable of pushing all the sample contained therein into the perforated tube (5) directed by the tubes (3) to the container (7) allocated inside a cooler (8) located near the collection. This same jet of compressed air that pushes the sample is capable of unclogging, if necessary, the holes (6) in the “U” tube (5), preventing water from entering the sampler (1) for the new cycle or collection is inefficient.

In the course of the sample from the outlet of the perforated tube (5) to the cooler (8) passes a ball valve (9) responsible for possible maintenance of the sampler (1).

After the ball valve (9), there is another three-way automatic divider valve (10) for sample selection to be collected or discarded (D), if discarded (D), the sample follows its flow to the tube (3) where it will be rejected and given the correct destination as the need of the place.

If the sample is collected, it follows the tube (3) until it reaches the sample collection and storage container (7), which has two sensors, and the level sensor (11) is responsible for verifying the level of the collected sample and The presence sensor (12) allows to indicate whether or not there is a container properly positioned inside the refrigerator (8). Upon reaching the level sensor (11), sampling should be suspended until the container (7) is replaced.

All sensors (11 and 12) and valves (4, 9 and 10) are controlled by the PLC (13) whose programming allows automatic sampling and the touch screen (14) which allows the human interface. -Machine to show all sampling data and enable spot sampling, and allow emergency stop in case of an unexpected event, which suspends the equipment immediately.

Thus, when material collection is completed by the level sensor (11), the compressed air is interrupted and the perforated tube (5) is refilled, allowing the cycle to be restarted. Before sampling, it is necessary to clean the perforated tube (5) and wait for its filling before collecting the sample. This should be done so as not to collect a sample that has been standing in the perforated tube (5) for an earlier period of time.

Therefore, the present patent application is novel and inventive due to the possibility that the automated water sampler ensures sample collection without clogging or failure of the manifold and by using equipment if simple constructivity and easy handling without The need for specialized labor for installation or maintenance, which added to the industrial application makes it worthy of patent privilege.
