Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, and in particular to an integrated device for the preparation and supply of papermaking additives. Background Technology

[0002] In the daily manufacturing of paper, papermaking additives are often added. Among them, wet strength agent is a commonly used preparation in paper production. However, wet strength agent needs to be diluted before use. Currently, when diluting wet strength agent, a mixing and stirring device is often required to mix the wet strength agent with water evenly.

[0003] However, currently, during the mixing and stirring of additives, the stirring blades drive the liquid to rotate synchronously. As the liquid rotates, centrifugal force causes some of the liquid to be temporarily stored between the two blades, resulting in a mediocre stirring effect. Therefore, improvements are needed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an integrated device for the preparation and supply of papermaking additives. This device solves the problem that in the prior art, during the mixing and stirring of additives, the stirring blades drive the liquid to rotate synchronously. As the liquid rotates, due to centrifugal force, some of the liquid will be temporarily stored between the two blades, resulting in poor stirring effect.

[0005] In view of this, the present invention provides an integrated device for the preparation and supply of papermaking additives, including a mixing tank, a feed inlet on the top of the mixing tank, a controller fixedly installed on one side of the mixing tank, and a circulating mixing component and a liquid supply component in the mixing tank;

[0006] The circulating mixing assembly includes a hollow mixing agitator, a drive motor, a suction port, a suction pipe, a diverter pipe, a liquid pump, a two-outlet-one-inlet solenoid valve, and a return pipe. The hollow mixing agitator is rotatably connected to the middle of the inner side of the mixing chamber. The drive motor is fixedly installed on the top of the mixing chamber. The suction port is opened on the surface of the blades of the hollow mixing agitator. The liquid pump and the two-outlet-one-inlet solenoid valve are both fixedly installed at the bottom of the mixing chamber. The suction pipe is fixedly installed between the bottom of the mixing chamber and the liquid pump. The diverter pipe is fixedly installed between the suction pipe and the mixing chamber. The return pipe is fixedly installed between the mixing chamber and the two-outlet-one-inlet solenoid valve.

[0007] Optionally, one end of the drive motor shaft is fixedly mounted on the top of the hollow mixing and stirring component, and the drive motor and the controller are electrically connected by wires.

[0008] Optionally, one end of the suction port is connected to the interior of the hollow mixing and stirring component.

[0009] Optionally, one end of the suction pipe is located at the connection between the mixing tank and the bottom of the hollow mixing and stirring component, and one end of the suction pipe is connected to the bottom of the hollow mixing and stirring component. The other end of the suction pipe is fixedly installed at the suction end of the liquid pump. One end of the diversion pipe is connected to the inside of the suction pipe, and the other end of the diversion pipe is connected to the inside of the mixing tank.

[0010] Optionally, one end of the reflux pipe is connected to the first output end of the two-outlet-one-inlet solenoid valve, and the other end of the reflux pipe is connected to the inside of the feed inlet.

[0011] Optionally, the drive motor and the two-out-one-in solenoid valves are all electrically connected to the controller via wires.

[0012] Optionally, the liquid supply assembly includes a liquid supply pipe and a flow meter. One end of the liquid supply pipe is fixedly installed and connected to the second output end of the two-outlet-one-inlet solenoid valve. The flow meter is fixedly installed at one end of the liquid supply pipe. The flow meter is electrically connected to the controller via a wire.

[0013] As can be seen from the above technical solutions, the embodiments of this utility model have the following advantages:

[0014] 1. This utility model discloses an integrated device for the preparation and supply of papermaking additives. By setting up a circulating mixing component, specifically, during mixing and stirring, the controller controls the first output end of the two-outlet and one-inlet solenoid valve to open. Then, the liquid pump connects to the inside of the hollow mixing and stirring component through the suction pipe and draws the mixed liquid through the suction port. Then, it flows back to the feed port through the return pipe and enters the mixing tank. This cycle is repeated to reduce the influence of centrifugal force and greatly improve the mixing effect during additive preparation.

[0015] 2. The present invention provides an integrated device for the preparation and supply of papermaking additives. Specifically, after the preparation is completed, the controller controls the second output end of the two-outlet and one-inlet solenoid valve to open. At this time, the liquid pump uses the suction port opened by the hollow mixing and stirring component and the bottom diversion pipe to simultaneously draw liquid. Liquid can be supplied by the liquid supply pipe. The structure is simple and convenient to use.

However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0024] The following describes in detail, with reference to the accompanying drawings, an integrated device for preparing and supplying papermaking additives according to an embodiment of the present invention.

[0025] Example 1

[0026] For easier understanding, please refer to Figures 1 to 4 An embodiment of the papermaking additive preparation and supply integrated device provided by this utility model includes a mixing tank 1, a feed inlet 2 on the top of the mixing tank 1, a controller 3 fixedly installed on one side of the mixing tank 1, and a circulating mixing component and a liquid supply component provided in the mixing tank 1.

[0027] The circulating mixing assembly includes a hollow mixing agitator 401, a drive motor 402, a suction port 403, a suction pipe 404, a diverter pipe 4041, a liquid pump 405, a two-outlet-one-inlet solenoid valve 406, and a return pipe 407. The hollow mixing agitator 401 is rotatably connected to the middle of the inner side of the mixing chamber 1. The drive motor 402 is fixedly installed on the top of the mixing chamber 1. The suction port 403 is opened on the surface of the blades of the hollow mixing agitator 401. The liquid pump 405 and the two-outlet-one-inlet solenoid valve 406 are both fixedly installed at the bottom of the mixing chamber 1. The suction pipe 404 is fixedly installed between the bottom of the mixing chamber 1 and the liquid pump 405. The diverter pipe 4041 is fixedly installed between the suction pipe 404 and the mixing chamber 1. The return pipe 407 is fixedly installed between the mixing chamber 1 and the two-outlet-one-inlet solenoid valve 406. One end of the drive motor 402 shaft is fixedly mounted... The drive motor 402 is electrically connected to the controller 3 via wires, mounted on the top of the hollow mixing and stirring component 401. One end of the suction port 403 is connected to the inside of the hollow mixing and stirring component 401. One end of the suction pipe 404 is located at the connection between the mixing box 1 and the bottom of the hollow mixing and stirring component 401, and one end of the suction pipe 404 is connected to the bottom of the hollow mixing and stirring component 401. The other end of the suction pipe 404 is fixedly installed at the suction end of the liquid pump 405. One end of the diversion pipe 4041 is connected to the inside of the suction pipe 404, and the other end of the diversion pipe 4041 is connected to the inside of the mixing box 1. One end of the return pipe 407 is connected to the first output end of the two-outlet-one-inlet solenoid valve 406, and the other end of the return pipe 407 is connected to the inside of the feed inlet 2. The drive motor 402 and the two-outlet-one-inlet solenoid valve 406 are both electrically connected to the controller 3 via wires.

[0028] It should be noted that by setting up a hollow mixing and stirring component 401, a two-outlet and one-inlet solenoid valve 406, and by setting up a suction pipe 404, a diversion pipe 4041, and a suction port 403, during mixing and stirring, the controller 3 controls the first output end of the two-outlet and one-inlet solenoid valve 406 to open. Then, the liquid pump 405 connects to the inside of the hollow mixing and stirring component 401 through the suction pipe 404 and draws the mixed liquid through the suction port 403. Then, it flows back to the feed port 2 through the return pipe 407 and enters the mixing tank 1. This cycle is repeated to reduce the influence of centrifugal force and greatly improve the mixing effect during the preparation of the additives. The function of the diversion pipe 4041 is to divert the liquid and facilitate the suction of the prepared additives at the bottom of the mixing tank 1 during liquid supply.

[0029] Example 2

[0030] In some embodiments, such as Figure 1 , Figure 2 As shown, the liquid supply assembly includes a liquid supply pipe 501 and a flow meter 502. One end of the liquid supply pipe 501 is fixedly installed and connected to the second output end of the two-outlet-one-inlet solenoid valve 406. The flow meter 502 is fixedly installed at one end of the liquid supply pipe 501. The flow meter 502 is electrically connected to the controller 3 by a wire.

[0031] It should be noted that by setting up the liquid supply pipe 501 and the flow meter 502, after the preparation is completed, the controller 3 controls the second output end of the two-outlet-one-inlet solenoid valve 406 to open. At this time, the liquid pump 405 uses the suction port 403 opened by the hollow mixing and stirring component 401 and the bottom diversion pipe 4041 to simultaneously draw liquid. The liquid supply pipe 501 can be used for liquid supply. The structure is simple and convenient. At the same time, the flow meter 502 can measure the flow rate during liquid supply. After the flow rate is reached, it can transmit to the controller 3 so that the controller 3 closes the second output end of the two-outlet-one-inlet solenoid valve 406 to stop the liquid supply.

[0032] The controller 3 and drive motor 402 in this utility model are known components and will not be described in detail here.

[0033] Working principle: During use, the raw materials are discharged into the mixing tank 1 through the feed inlet 2. Then, the drive motor 402 drives the hollow mixing agitator 401 to stir. At this time, the controller 3 controls the first output end of the two-outlet, one-inlet solenoid valve 406 to open. Then, the liquid pump 405 is connected to the inside of the hollow mixing agitator 401 through the suction pipe 404 and draws the mixture through the suction port 403. Then, it flows back to the feed inlet 2 through the return pipe 407 and enters the mixing tank 1. This cycle is repeated to reduce the influence of centrifugal force. Furthermore, it greatly improves the mixing effect during the preparation of additives. After the preparation is completed, the controller 3 controls the second output end of the two-outlet-one-inlet solenoid valve 406 to open. At this time, the liquid pump 405 uses the suction port 403 opened by the hollow mixing and stirring component 401 and the bottom diversion pipe 4041 to simultaneously draw liquid. Liquid can be supplied by the liquid supply pipe 501. At the same time, the flow meter 502 can measure the flow rate during liquid supply. After the flow rate is reached, it can transmit to the controller 3 so that the controller 3 closes the second output end of the two-outlet-one-inlet solenoid valve 406 to stop the liquid supply.
