Detailed Description
The utility model will be described in more detail below with reference to the accompanying drawings:
the following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the utility model more readily understood by those skilled in the art, and thus will more clearly and distinctly define the scope of the utility model. The directional terms used in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., refer to the directions of the attached drawings. Accordingly, the directional terms used are used for explanation and understanding of the present invention, and are not used for limiting the present invention.
Referring to fig. 1, the control device for rapidly adjusting the concentration of the starch glue solution is arranged between a glue solution storage tank 6 and a feeding tank 9, and the control device comprises a dilution water tank 1, a dilution water pump 2, a concentration calculator 3, a second flow meter 4, an adjusting valve 5, a glue solution pump 7, a first flow meter 8 and pipelines for connecting the above components.
The storage tank 6 is sequentially connected with a glue solution pump 7 and a first flow meter 8 through a pipeline, and glue solution in the glue solution storage tank 6 is pumped by the glue solution pump 7 to flow through the first flow meter 8, mixed with release water and then conveyed to the feeding tank 9.
The dilution water tank 1 is sequentially connected with the dilution water pump 2, the second flow meter 4 and the regulating valve 5 through pipelines, and hot water in the dilution water tank 1 is pumped by the dilution water pump 2, flows through the second flow meter 4 and the regulating valve 5, is mixed with glue solution on a glue solution pipe, and then enters the feeding tank 9.
The dilution water pipe is connected with the glue solution pipe at an angle of 45 degrees, so that the dilution water and the glue solution are premixed and then flow into the feeding groove 9, a better mixing effect can be obtained, and the production efficiency is improved. The feeding groove 9 is provided with a stirrer, so that the glue solution can be fully stirred and uniformly mixed.
The first flowmeter 8 and the second flowmeter 4 are electromagnetic flowmeters, and they are electrically connected to the consistency calculator 3 and the paper machine DCS control system (not shown), respectively, and the regulating valve 5 and the consistency calculator 3 are also electrically connected to the paper machine DCS control system.
The DCS control system of the paper machine collects real-time data of the first flowmeter 8, the second flowmeter 4 and the concentration calculator 3 to calculate and compare, and sends a flow instruction to the regulating valve 5. The regulating valve 5 is a pneumatic regulating valve, is safe and reliable, and automatically regulates the opening after receiving a flow instruction of a DCS (distributed control system) of the paper machine so as to regulate the flow.
The concentration calculator 3 calculates and obtains current flow values of the first flowmeter 8 and the second flowmeter 4, calculates a current concentration value, compares a required concentration value preset in the system with the current concentration value, and if the current concentration value is greater than the required concentration value, the paper machine DCS control system sends a flow increasing instruction to the regulating valve 5; if the current concentration value is smaller than the required concentration value, the paper machine DCS control system sends a flow reduction instruction to the regulating valve 5; therefore, the concentration of the glue solution entering the feeding groove 9 is controlled in real time.
The required concentration value in the DCS control system of the paper machine is a preset value, and the specific numerical value is determined according to the paper product required to be produced at present, such as: a concentration value of 5.00% is required when a paper product with a basis weight of 120 g is produced, and a concentration value of 5.50% is required when a paper product with a basis weight of 140 g is produced. Since the concentration of the dope in the stock tank 6 is fixed, only the required flow rate of the dilution water needs to be controlled to control the concentration of the dope flowing into the stock tank 9. In practice, the required flow rate of the dilution water { (dope concentration-required concentration value/required concentration value of the stock tank) } first flowmeter flow rate value, for example: when the concentration of the dope in the stock tank 6 was 8.00%, the required concentration value was 5.00%, and the flow value of the first flow meter (i.e., the current flow rate of the dope) was 11.8m3/h, the required flow rate of the dilution water was calculated as { (8.00-5.00)/5.00 }. 11.8 as 7.08m 3/h; for another example: when the dope concentration in the stock tank 6 was 8.00%, the required concentration value was 5.50%, and the flow rate of the first flowmeter (i.e., the current dope flow rate) was 11.8m3/h, the required flow rate of the dilution water was calculated as { (8.00-5.50)/5.50 }. 11.8 as 5.36m 3/h.
The utility model controls the concentration of the glue solution flowing into the feeding trough by changing the flow of the dilution water through online dilution, can quickly adjust the concentration of the starch according to the concentration required by production varieties, has flexible and convenient operation, is slightly influenced by external factors, and ensures the stable quality of products.
The above-mentioned embodiments are only preferred embodiments of the present invention, and all equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the claims of the present invention.
