[0002] In industrial production fields such as pulp and paper making, vertical hydraulic pulpers are key equipment for crushing waste paper, books and other materials. However, in actual use, there are many problems in the feeding process. Traditional vertical hydraulic pulpers lack effective protective measures when feeding, which makes it easy for pulp to splash out at the moment of feeding and during the pulping process. Therefore, anti-splash components need to be installed. Although some pulpers are equipped with some anti-splash devices to prevent pulp from splashing out, most of them still require manual operation and control. It is difficult to automatically and quickly close the feed inlet after the material is fed, which makes it inconvenient to block the pulp splashing. This can easily lead to a dirty and messy working environment, and may even cause injury to operators. It also increases the cost of subsequent cleaning and maintenance. Utility Model Content

[0023] Please see Figure 1-5 This utility model provides a technical solution: a vertical hydraulic pulper feed splash protection device, including a vertical hydraulic pulper 1, a fixed frame 2 fixedly connected to the top of the vertical hydraulic pulper 1, the fixed frame 2 being L-shaped, a drive motor 3 fixedly connected to the top of the fixed frame 2, the output end of the drive motor 3 rotating through to the bottom of the fixed frame 2 and fixedly connected to a stirring rod 4, a crushing blade 5 fixedly sleeved on the outer surface of the stirring rod 4, grooves 8 being provided on both sides of the inner wall of the vertical hydraulic pulper 1, and a splash protection component being provided inside the vertical hydraulic pulper 1, the splash protection component including two splash protection plates 11, a semi-circular groove 12 being provided at the opposite ends of the two splash protection plates 11, the interior of the two semi-circular grooves 12 being adapted to the outer surface of the stirring rod 4.

[0024] Furthermore, each of the two splash guards 11 is fixedly connected to a fixing plate 10 at its opposite ends. The outer surfaces of the two fixing plates 10 are slidably connected to the inner walls of the corresponding grooves 8. Each of the two fixing plates 10 is fixedly connected to a rotating column 9 at its opposite ends. Both ends of the two rotating columns 9 are provided with torsion springs 16.

[0025] Furthermore, circular grooves 17 are provided on both sides of the inner wall of the two grooves 8. The interior of the four circular grooves 17 is rotatably connected to one end of the corresponding rotating column 9. The four torsion springs 16 are fixedly installed inside the corresponding circular grooves 17.

[0026] Furthermore, each of the two splash guards 11 has a sloping groove 13 at its top, and both sloping grooves 13 are located on one side of the stirring rod 4.

[0027] Furthermore, a circular groove 6 is provided at the bottom of the inner wall of the vertical hydraulic pulper 1, and a filter screen 7 is fixedly installed inside the circular groove 6, with the filter screen 7 located below the crushing blade 5.

[0028] Furthermore, the vertical hydraulic pulper 1 has a pulp trough 15 inside, the inside of the pulp trough 15 is connected to the inside of the circular through groove 6, and the inside of the pulp trough 15 is connected to the inside of the discharge pipe 14.

[0029] Furthermore, during the feeding stage, waste books and other materials are fed into the two inclined troughs 13. The two splash guards 11 are then subjected to downward pressure from the material. The two splash guards 11 then drive the corresponding fixed plates 10 to rotate the corresponding rotating columns 9. The two rotating columns 9 then rotate and compress the corresponding torsion springs, causing the two splash guards 11 to automatically rotate downward and open. The material then slides into the interior of the vertical hydraulic pulper 1. When the pressure on the two splash guards 11 disappears, the torsion springs 16 provide a restoring force to reset the two splash guards 11, thereby automatically sealing the internal space of the pulper and preventing material splashing. This further improves the practicality of the splash protection device.

[0030] Furthermore, when the drive motor 3 starts and drives the stirring rod 4 and the crushing blade 5 to rotate to start the pulping work, the material is stirred and crushed under the action of the crushing blade 5. Then, the crushed material is initially filtered through the filter screen 7. The qualified pulp enters the pulp tank 15 through the circular channel 6 and is discharged through the discharge pipe 14. The filter screen 7 can intercept larger particles or incompletely crushed materials, allowing them to continue to be crushed in the pulper, thus ensuring the quality of the output.

[0031] Furthermore, through the design of two splash guards 11 in conjunction with torsion springs 16, the two splash guards 11 can automatically close the feed inlet when the material enters the interior of the vertical hydraulic pulper 1. Thus, after the material is fed in, the two splash guards 11 can easily block the splashing of pulp. The operation process is simple and quick, thereby improving the practicality of the splash protection device.

[0032] Structural Description:

[0033] Vertical hydraulic pulper 1: As the main equipment of the entire unit, it is the core space for material crushing and processing, providing a place for pulping operations. Other structures inside it work together to support pulping and splash prevention functions.

[0034] Fixed frame 2: L-shaped, fixedly connected to the top of the vertical hydraulic pulper 1, mainly serving to support and fix the drive motor 3, ensuring the stable installation of the drive motor 3, and providing a power base for the rotation of the mixing rod 4.

[0035] Drive motor 3: Installed at the top of the fixed frame 2, its output end rotates through to the bottom of the fixed frame 2, providing rotational power to the stirring rod 4, driving the stirring rod 4 and the crushing blade 5 to rotate, realizing the stirring and crushing functions of the material.

[0036] Stirring rod 4: It is fixedly connected to the output end of drive motor 3 and rotates under the drive of drive motor 3. Crushing blade 5 is fixedly sleeved on its outer surface. It drives the crushing blade 5 to crush the material by rotating itself.

[0037] Crushing blade 5: It is fixedly sleeved on the outer surface of the stirring rod 4. As the stirring rod 4 rotates, it cuts and crushes the material fed into the vertical hydraulic pulper 1, breaking the material into pulp.

[0038] Circular through groove 6: Located at the bottom of the inner wall of the vertical hydraulic pulper 1, it connects the inside of the pulper with the pulp tank 15 and serves as the discharge channel for pulp. Qualified pulp filtered by the filter screen 7 enters the pulp tank 15 through this groove.

[0039] Filter screen 7: Fixedly installed inside the circular channel 6, located below the crushing blade 5, to perform preliminary filtration of the crushed material, intercepting larger particles or incompletely crushed material, allowing qualified pulp to pass through, and ensuring the quality of the output.

[0040] Groove 8: Used to install rotating column 9 to realize the automatic opening and closing action of splash guard 11.

[0041] Rotating column 9: When the splash guard 11 is subjected to material pressure or the action of torsion spring 16, it serves as a pivot point to drive the splash guard 11 to rotate.

[0042] Fixed plate 10: It serves to connect the splash guard plate 11 and the rotating column 9, and at the same time transmits the force on the splash guard plate 11 to the rotating column 9.

[0043] Splash guard plate 11: A key component of the splash guard assembly. Two splash guard plates 11 are arranged opposite each other inside the vertical hydraulic pulper 1. They open under the pressure of the material during feeding and automatically reset and close the feed inlet under the action of the torsion spring 16 after the material enters, thus preventing material from splashing.

[0044] Semicircular groove 12: When the splash guard 11 is reset, the semicircular groove 12 will be close to the stirring rod 4. In this case, the two semicircular grooves 12 will not affect the normal rotation of the stirring rod 4.

[0045] Inclined trough 13: Used to guide the material smoothly into the vertical hydraulic pulper 1 during feeding, reducing the possibility of material splashing.

[0046] Discharge pipe 14: Connected to the inside of pulp tank 15, it is the final discharge channel for qualified pulp, and transports the pulp that has been filtered by filter screen 7 into pulp tank 15 to subsequent processing steps.

[0047] Slurry tank 15: Used to collect qualified pulp after being filtered by filter screen 7 and discharge the pulp through discharge pipe 14.

[0048] Torsion spring 16: Located at both ends of the rotating column 9 and inside the circular groove 17, it provides restoring force for the splash guard 11. After the material pressure disappears, it pushes the rotating column 9 to rotate, so that the splash guard 11 automatically resets and closes the feed port.

[0049] Circular groove 17: used to install rotating column 9 and torsion spring 16, providing rotation space for rotating column 9, ensuring that torsion spring 16 can effectively act on rotating column 9, and realizing the reset function of splash guard 11.

[0050] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
