Description

Technical Field

[0001] This utility model relates to the field of slurry mixing technology, and in particular to a mixing slurry tank filling device that facilitates quantitative filling. Background Technology

[0002] The mixing tank filling device is a key piece of equipment in the pulp and paper industry. It mixes different types of pulp in a specific ratio and evenly delivers the mixture into the pulp tank, providing a mixed pulp that meets quality requirements for subsequent papermaking processes. A convenient, quantitative mixing tank filling device allows for precise control of the pulp and mold inhibitor delivery ratio and dosage, thereby directly improving production efficiency, product quality, and cost control.

[0003] However, when using a mixing tank filling device, the fibers in the pulp settle rapidly during low-speed mixing or when the machine stops, forming a thick layer of pulp at the bottom, which can lead to uneven mixing or pipe blockage. In addition, waste paper pulp contains adhesives, which will increase the viscosity of the pulp at low temperatures, causing the blades to bear greater torque, and the motor needs to output more torque to overcome the pulp resistance.

[0004] Therefore, this application provides a mixing slurry tank injection device that facilitates quantitative injection, in order to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a convenient quantitative mixing pulp tank filling device. This device can effectively prevent fiber sedimentation in the pulp and also prevent the waste pulp from becoming too viscous due to excessively low temperatures.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 — Figure 4 An embodiment of this utility model provides a mixing slurry tank filling device for easy quantitative filling, including a slurry inlet pipe 2, a mildew inhibitor tank 5, an industrial chiller 12, and a tank body 1. A water pump 6 is fixedly connected to the front end and one side of the outer wall of the mildew inhibitor tank 5. The outlets of the two water pumps 6 are respectively fixedly connected to a first pipe 7 and a second pipe 8. An electric valve 9 and a second flow meter 10 are installed around the first pipe 7 and the second pipe 8. A first flow meter 3 is installed around the slurry inlet pipe 2. An ultrasonic liquid level sensor is installed on the top surface of the inner tank 19 on the other side. A pH meter is installed on one side of the inner wall of the inner tank 19.

[0025] Specifically, before using the device, the anti-mold agent is first filled into the anti-mold agent tank 5. The valve from the previous process is opened to inject pulp into the pulp inlet pipe 2, and the pulp is transported to the inner liner 19 inside the tank 1. The flow rate of the pulp can be observed through the first flow meter 3. Then, the water pump 6 and the electric valve 9 connected to the first pipe 7 are started. The water pump 6 sends the anti-mold agent from the anti-mold agent tank 5 into the pulp inlet pipe 2. The flow rate of the anti-mold agent can be monitored in real time through the corresponding second flow meter 10. Then, it is mixed by the mixing and conveying pump 4 and sent into the inner liner. Inside the inner tank 19, the second motor 14 drives the spiral stirring blades 16 to stir and prevent fiber sedimentation. A pH meter monitors the pH value of the pulp in real time, and an ultrasonic level sensor detects the liquid level inside the inner tank 19. Once the target height is reached, the first motor 11 drives the stirring rollers 15 to stir and ensure the antifungal agent is mixed more evenly. Simultaneously, by observing the pH meter, another water pump 6 is activated to send the antifungal agent from the antifungal agent tank 5 into the inner tank 19 for adjustment and stirring. After reaching the acceptable level, the agent is discharged through the pulp outlet pipe 13. If the temperature is too high or too low, the electric heating element 18 can be activated to raise the temperature, or the industrial chiller 12 can be activated to continuously send cold water into the circulation pipe 17 for cooling. The pH meter can monitor the pH value of the pulp inside the inner tank 19 in real time. The ultrasonic level sensor can monitor the pulp level in real time to prevent over- or under-addition of antifungal agent and facilitate subsequent addition of antifungal agent. Three support legs are evenly spaced around the lower end of the inner tank 19.

[0026] Reference Figure 1 — Figure 4 A stirring rod 15 is rotatably mounted on the top surface of the inner liner 19 via a sealed bearing, and a spiral stirring blade 16 is rotatably mounted on the bottom surface of the inner liner 19 via a sealed bearing. A first motor 11 is fixedly mounted on the upper end surface of the inner liner 19, and the lower output end of the first motor 11 passes through the upper end surface of the inner liner 19 and is fixedly connected to the stirring rod 15. A second motor 14 is fixedly mounted on the lower end surface of the inner liner 19, and the upper output end of the second motor 14 passes through the lower end surface of the inner liner 19 and is fixedly connected to the spiral stirring blade 16.

[0027] Specifically, the first motor 11 drives the stirring rod 15 to rotate and stir the pulp inside the inner liner 19. The second motor 14 drives the spiral stirring blade 16 to prevent fiber sedimentation. The support legs can lift the tank 1 and the inner liner 19 to a certain height, making room for the placement of the second motor 14.

[0028] Reference Figure 3 , Figure 4 The tank body 1 is fixedly provided with an inner liner 19. The inner liner 19 is surrounded by a circulation pipe 17 and an electric heating pipe 18. The water outlet of the industrial chiller 12 passes through the outer wall of the tank body 1 and is fixedly connected to the water inlet of the circulation pipe 17. The water inlet of the industrial chiller 12 passes through the outer wall of the tank body 1 and is fixedly connected to the water outlet of the circulation pipe 17.

[0029] Specifically, the heating element 18 provides a certain temperature to the inner tank 19 for heating. The industrial chiller 12 continuously cools the hot water and sends the cooled water into the circulation pipe 17 to absorb heat from the inner tank 19. The industrial chiller 12 is a water cooling device capable of providing constant temperature, constant flow, and constant pressure cooling. A certain amount of water is injected into the internal water tank of the industrial chiller 12, and the water is cooled by the refrigeration system. Then, the internal water pump 6 injects the chilled water into the equipment that needs cooling. The chilled water carries away the heat from inside the machine, and the hot water is returned to the water tank for further cooling. This cycle of cooling and exchange achieves the purpose of cooling the equipment.

[0030] Reference Figure 1 , Figure 2 A mixing and conveying pump 4 is fixedly connected to one end of the outer wall of the slurry inlet pipe 2. The outlet end of the mixing and conveying pump 4 passes through the front end of the tank body 1 and is fixedly connected to the inner liner 19. One end of the outer wall of the first pipe 7 is fixedly connected to the slurry inlet pipe 2. One end of the outer wall of the second pipe 8 is fixedly connected to the upper end face of the inner liner 19. A slurry outlet pipe 13 is fixedly connected to the lower end face of the rear end of the outer wall of the inner liner 19, passing through the tank body 1. Flange connectors are fixedly installed on the rear end of the outer wall of the slurry outlet pipe 13 and the upper end face of the outer wall of the slurry inlet pipe 2.

[0031] Specifically, two water pumps 6 can deliver the anti-mold agent inside the anti-mold agent tank 5 into the pulp inlet pipe 2 and the inner tank 19 via the first pipe 7 and the second pipe 8, respectively. A mixing and conveying pump 4 can pre-stir the pulp and anti-mold agent inside the pulp inlet pipe 2 before introducing it into the inner tank 19. If the pH value inside the inner tank 19 is not up to standard, the anti-mold agent introduced through the second pipe 8 can be fine-tuned. Two electric valves 9 can control the flow of the anti-mold agent inside the first pipe 7 and the second pipe 8, respectively. Two second flow meters 10 can monitor the flow rate of the anti-mold agent inside the first pipe 7 and the second pipe 8 in real time. A first flow meter 3 can monitor the flow rate of the pulp inside the pulp inlet pipe 2 in real time.

[0032] Working principle: When using this device, pulp is injected through the pulp inlet pipe 2. Simultaneously, the corresponding water pump 6 is activated to add anti-mildew agent into the pulp inlet pipe 2. Subsequently, the pulp and anti-mildew agent are stirred by the mixing and conveying pump 4 and sent into the inner tank 19. The first motor 11 drives the stirring roller 15 to stir the pulp, and the second motor 14 drives the spiral stirring blade 16 to stir and prevent sedimentation. The pH value of the pulp is observed using a pH meter, and the corresponding water pump 6 is activated to continue injecting anti-mildew agent into the inner tank 19. Once the pH value is reached, the pulp is discharged through the pulp outlet pipe 13.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
