Technical Field

The invention belongs to the technical field of aquatic product production testing, and particularly relates to a reaction liquid quantitative adding system for gelatin production.

Background

In the production process of collagen and gelatin, acid or alkali is often required to be automatically added to a use point through a pump and a pipeline, for example, gel extraction, pH value adjustment, CIP and the like, the specific structure of the device is shown in figure 1, an acid-alkali storage tank 1 is connected with a use point 6 through a pipeline 9, a delivery pump 2 and a flow meter 3, the acid-alkali addition is realized by controlling the operation of the delivery pump 2, and the flow meter 3 is used for monitoring the amount of the added acid and alkali. However, when the acid or the alkali is added in a precise and quantitative manner in some processes, the following problems exist in the automatic acid and alkali adding manner:

1. the automatic quantitative addition is influenced by factors such as the length of a pipeline, the sensitivity of an instrument, the signal feedback time, the height difference between a using point and a storage tank and the like, and the automatic quantitative addition taking 'liter' as a unit is difficult to realize in the actual production process; 2. if air is mixed in the conveying pipeline, the metering of the instrument is influenced; 3. when the pipeline is filled with liquid and the pipeline is not filled with liquid, the metering of the instrument is different; 4. when the point of use is close to the end of the reaction and fine adjustment is required, for example, when 0.1 liter of the solution is added, it is difficult to achieve automatic metering. And if the precise automatic metering addition is realized by using a high-precision instrument, the investment and maintenance cost is extremely high, and enterprises cannot bear the high-precision instrument.

Disclosure of Invention

The invention aims to provide a reaction liquid quantitative adding system for gelatin production, which is used for accurately and quantitatively adding reaction liquid to a use point.

The reaction liquid quantitative adding system for gelatin production is formed by connecting a reaction liquid storage tank, a delivery pump, a quantitative tank and a liquid outlet valve in sequence through pipelines; the quantitative tank is made of transparent or semitransparent materials, and a gradiometer is arranged on the tank wall of the quantitative tank.

The working principle of the reaction liquid quantitative adding system for gelatin production is as follows:

firstly, arranging a quantitative tank above a using point, adding a reaction liquid to be quantitatively added into the quantitative tank through a delivery pump, ensuring that the height of the reaction liquid in the quantitative tank is lower than the position of a reaction liquid inlet of the quantitative tank, and reading the original volume A of the reaction liquid in the quantitative tank by using a scale; and subtracting the volume C of the reaction liquid required to be added from the original volume A of the reaction liquid to obtain a difference B between the original volume A and the volume C of the reaction liquid, opening a liquid outlet valve of the quantitative tank to reduce the volume of the reaction liquid of the quantitative tank to the position B, and closing the liquid outlet valve, so that the volume of the reaction liquid added at this time is A-B = C, and accurate metering is realized.

Furthermore, a flow meter is connected in the pipeline, so that the delivery valve and the liquid outlet valve are opened simultaneously under the condition of monitoring the flow meter, and the rapid quantitative addition of a large amount of reaction liquid can be realized.

Furthermore, a plurality of temporary storage concave parts are arranged at the bottom of the quantifying tank, and the top surfaces of all the temporary storage concave parts are flush; the liquid outlet valves are multiple and are respectively arranged at the bottoms of the corresponding temporary storage concave parts. Through the work of control delivery valve, can make the reaction liquid level in the ration jar just with the top surface parallel and level of the concave part of keeping in, the volume of the reaction liquid in every concave part of keeping in like this all is fixed knowably, and the experimenter can open the play liquid valve of certain or some concave part of keeping in as required, and the reaction liquid in the concave part of keeping in that will correspond is whole to be put to the reaction point, realizes quick ration input reaction liquid.

Further, for convenient observation, the tank wall of the quantitative tank is provided with a volume mark representing the volume of each temporary storage concave part at the position corresponding to each temporary storage concave part.

According to the reaction liquid quantitative adding system for gelatin production, the quantitative tank is arranged, so that the adding errors caused by overlong pipelines and pipeline conditions (whether air exists in the pipelines, whether the reaction liquid in the pipelines is full or not) can be avoided, accurate quantitative addition and 0.1L-level micro addition can be determined, the investment and maintenance cost is low in automation, and the system has good practicability.
