Technical Field

[0001] This utility model relates to the field of papermaking technology, and in particular to a papermaking pulp pump device for stable pulp supply. Background Technology

[0002] A paper machine is a general term for a complete set of equipment that links different parts of the pulp to form a paper web. It includes main components such as the headbox, wire section, press section, dryer section, calender, winding machine, and drive section, as well as auxiliary systems such as steam, water, vacuum, lubrication, and heat recovery. A paper machine is a machine that produces paper from a pulp suspension that meets the requirements of papermaking through processes such as dewatering and forming with a filter, mechanical extrusion dewatering, and drying.

[0003] During the papermaking process, a pulp pump is needed to deliver the pulp to a designated location for papermaking operations.

[0004] During the pulp delivery process, the amount of pulp supplied by the pulp pump is difficult to control due to the variations in the thickness and size of the paper, which can lead to uneven paper specifications. In addition, during the pulp supply process, the pulp may separate or settle in the pulp tank during storage, resulting in different pulp contents in the extracted pulp solution, which affects the paper quality.

[0005] Therefore, this application proposes a paper pulp pump device with stable pulp supply to solve the problems in the background art. Utility Model Content

Through the coordinated design between the pulp storage tank 1, the feeding mechanism, the conveying mechanism, the metering tank 12, the level sensor 13, the light sensor 14, and the control panel 15, it is possible not only to avoid pulp stratification or sedimentation, but also to achieve the effect of metered pulp delivery, thereby achieving the effect of stable pulp supply.

[0032] In this embodiment, the pulp conveying pump 4 is connected to the control panel 15. The top of the pulp storage tank 1 is sealed with a diversion pipe 5. One end of the diversion pipe 5 is sealed with a three-way pipe. One end of the three-way pipe is sealed with one end of the pulp conveying pump 4. Driven by the pulp conveying pump 4, the pulp is conveyed into the diversion pipe 5 and discharged through multiple discharge ports on the diversion pipe 5, acting on multiple transmission plates 3. This causes the multiple transmission plates 3 to drive the rotating shaft 2 to rotate on the pulp storage tank 1. At the same time, one end of the rotating shaft 2 drives the corresponding transmission roller 9 to rotate, thereby achieving the effect of driving the conveyor belt 10.

[0033] In this embodiment, one end of the three-way pipe is sealed and connected to the feeding pipe 7. Solenoid valves are installed on the feeding pipe 7 and the diversion pipe 5 and connected to the control panel 15. They are used to control the opening and closing of the feeding pipe 7 and the diversion pipe 5. Multiple discharge ports on the diversion pipe 5 correspond to multiple transmission plates 3.

[0035] In this embodiment, the conveyor belt 10 is provided with multiple pulp molds 11, and the top of the bracket 8 is fixedly installed with a metering box 12. The bottom of the metering box 12 is sealed and connected to a discharge pipe and corresponds to the multiple pulp molds 11. Through the function of the discharge pipe, a metered amount of pulp in the metering box 12 can be discharged into the corresponding pulp mold 11.

[0036] In this embodiment, one end of the feeding pipe 7 is sealed to the metering tank 12. A liquid level sensor 13 is fixedly installed on the metering tank 12. The liquid level sensor 13 is adapted to the metering tank 12 and connected to the control panel 15. Through the function of the liquid level sensor 13, the pulp level of the metering tank 12 can be detected in real time, and the detected information is transmitted to the control panel 15.

[0037] In this embodiment, a through hole is provided on the bracket 8, and a light sensor 14 is fixedly installed in the through hole. The light sensor 14 corresponds to multiple pulp molds 11 and is connected to the control panel 15. The light sensor 14 can facilitate the detection of the position of the pulp molds 11 and transmit the detection information to the control panel 15.

[0038] In this embodiment, the rotating shaft 2 is fitted with a sealed bearing 1. The outer wall of the sealed bearing 1 is fixedly connected to the pulp storage tank 1, which improves the sealing performance and facilitates the rotating shaft 2 to drive the corresponding transmission roller 9. The other end of the rotating shaft 2 is fixedly connected to a protrusion. The protrusion is rotatably connected to the inner wall of the pulp storage tank 1. The rotating shaft 2 and multiple transmission plates 3 are all adapted to the pulp storage tank 1.

[0039] In this embodiment, multiple transmission plates 3 discharge material at equal intervals on the rotating shaft 2, which facilitates driving the rotating shaft 2. Multiple feed pipes are sealed and connected to the diversion pipe 6. One end of each feed pipe is sealed and connected to the bottom of the pulp storage tank 1, which facilitates the extraction of pulp from different positions at the bottom of the pulp storage tank 1.

[0040] In this embodiment, multiple pulp molds 11 are arranged at equal intervals on the conveyor belt 10, and a solenoid valve is installed on the discharge pipe and connected to the control panel 15 for regulating the opening and closing of the discharge pipe.

[0041] Working principle: When in use, first connect the power supply and drive and control the pulp conveying pump 4 and multiple solenoid valves through the preset program in the control panel 15;

[0042] First, the solenoid valve on the feed pipe 7 is opened, and the pulp at the bottom of the pulp storage tank 1 is drawn out by the drive of the pulp conveying pump 4 and the cooperation of the diversion pipe 6. The pulp is then transported to the metering tank 12 through the cooperation of the three-way pipe and the feed pipe 7. During this process, the level sensor 13 monitors the level of the pulp in the metering tank 12 and transmits the detected information to the control panel 15. When the pulp in the metering tank 12 reaches the preset value, the control panel 15 controls the solenoid valve on the feed pipe 7 to close and the solenoid valve on the diversion pipe 5 to open through the preset program.

[0043] At this time, driven by the pulp conveying pump 4, the pulp is conveyed into the diversion pipe 5 and discharged through multiple discharge ports on the diversion pipe 5, acting on multiple transmission plates 3. This causes the multiple transmission plates 3 to drive the rotating shaft 2 to rotate on the pulp storage tank 1. At the same time, one end of the rotating shaft 2 drives the corresponding transmission roller 9 to rotate. Through the cooperation between the two transmission rollers 9 and the conveyor belt 10, the conveyor belt 10 conveys the pulp mold 11. Then, when the pulp mold 11 triggers the light sensor 14, it transmits the information to the control panel 15. At this time, the solenoid valve on the discharge pipe at the bottom of the metering tank 12 is opened by the preset program in the control panel 15, and the pulp conveying pump 4 is stopped. This allows the pulp stored in the metering tank 12 to be discharged into the corresponding pulp mold 11. During this process, the pulp level in the metering tank 12 will drop. When the level drops to the preset value, the level sensor 13 transmits the information to the control panel 15.

[0044] At this time, the solenoid valves on the discharge pipe and the diversion pipe 5 are closed by the preset program in the control panel 15, and the solenoid valve on the feed pipe 7 is opened at the same time to start the pulp conveying pump 4. Then the above operation is performed again.

[0045] During the process of discharging pulp through the diversion pipe 5 and interacting with multiple transmission plates 3, the pulp in the pulp storage tank 1 can be stirred, thereby preventing pulp stratification or sedimentation. At the same time, the quantitative tank 12 and the level sensor 13 can achieve the effect of quantitative pulp delivery, thereby achieving a stable pulp supply.

[0046] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, it not only avoids pulp stratification or sedimentation but also achieves quantitative pulp delivery, thereby ensuring a stable pulp supply. Moreover, the structure is simple and the practicality is higher.
