Description

Technical Field

[0001] This utility model relates to the field of pulping technology, specifically to a high-efficiency hydraulic pulper with a water flow guiding structure. Background Technology

[0002] A pulper is a machine that breaks down, fluidizes, and disperses raw materials such as pulp boards, waste paper, and other materials from the production process into fibrous pulp. In the papermaking process, the pulper provides the necessary raw material preparation for subsequent paper manufacturing. The working principle of a pulper is mainly based on the combination of mechanical and hydraulic forces. Specifically, in wet nonwoven fabric processes, such as hydraulic pulpers, a rotating disc is located in the center of the bottom of the bowl, with several blades mounted on it. Around the bottom of the disc are fixed discs equipped with multiple blades. The rotating disc is driven by a motor located below, causing the blades on the disc to rotate, creating a violent turbulent circulation. The intense agitation and shearing of the water, along with the friction and kneading between the pulp particles, disperse the paper, saponify the ink, and expand the fibers, thus completing the pulping function.

[0003] A search revealed a Chinese utility model patent document with patent number CN214362505U, which discloses an advanced and efficient hydraulic pulper. This utility model provides an advanced and efficient hydraulic pulper that is easy to use and can simply and effectively crush pulp raw materials. At the same time, it avoids the raw materials from clogging the holes on the honeycomb square screen plate during crushing, and is simple and convenient to operate. However, it is not easy to control the direction of water flow during crushing, which can easily reduce the effect of hydraulic action and further affect the crushing effect of pulp.

[0004] To address this, a high-efficiency hydraulic pulper with a water flow guiding structure is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency hydraulic pulper with a water flow guiding structure, which solves the technical problem that the water flow direction is not easy to control during the crushing process in existing hydraulic pulpers, resulting in a reduction in the hydraulic effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-efficiency hydraulic pulper with a water flow guiding structure includes a crushing tank. A feed hopper is fixedly installed at the top of the crushing tank, and a discharge pipe is connected to the bottom of the crushing tank. A high-efficiency crushing component is installed inside the crushing tank. The high-efficiency crushing component includes a rotating seat rotatably installed at the bottom of the crushing tank. Impeller blades and cutting blades are fixedly installed at the bottom of the rotating seat. A spiral blade is fixedly installed at the center of the top of the rotating seat. A motor is fixedly installed at the center of the bottom of the crushing tank. The output end of the motor is fixedly connected to the central shaft of the rotating seat. A filter plate is also provided at the bottom of the crushing tank, and the central shaft of the rotating seat passes through the center of the filter plate. A water flow guiding component is also provided inside the crushing tank.

[0008] Preferably, the number of cutting blades and the number of impeller blades are both one, the cutting blades and the impeller blades are arranged alternately, and the height of the impeller blades is higher than the height of the cutting blades.

[0009] Preferably, a PLC controller is fixedly installed at the front end of the crushing tank, and the PLC controller is electrically connected to the motor.

[0010] Preferably, the tip of the helical blade extends to the top of the crushing tank.

[0011] Preferably, the water flow guiding assembly includes a water injection pipe fixedly installed on the side wall of the crushing tank, a corrugated connecting pipe connected to the inner side of the water injection pipe, a nozzle fixedly connected to the other end of the corrugated connecting pipe, a connecting rod fixedly installed at the top of the nozzle, and the rotation range of the nozzle is between -45° and 45°.

[0012] Preferably, the top end of the connecting rod extends outside the crushing tank, and the top end of the crushing tank is also fixedly installed with an adjusting motor electrically connected to the PLC controller, and the output end of the adjusting motor is fixedly connected to the connecting rod.

[0013] Preferably, a control valve electrically connected to the PLC controller is also fixedly installed at the top of the water injection pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. By setting up a high-efficiency crushing component, after the motor is started by the PLC controller, the motor can drive the rotating seat to rotate at high speed in the crushing tank. At this time, the cutting blade at the bottom of the rotating seat can crush the carton, and the impeller blades can drive the pulp to flow continuously in the crushing tank, which can ensure the crushing effect of the pulp. During the rotation of the rotating seat, the spiral blades can rotate synchronously. At this time, the spiral blades can drive the pulp at the bottom of the crushing tank to flow upward, which can make the pulp distribution more uniform and improve the crushing effect of the pulp.

[0016] 2. By setting up a water flow guiding component, when the user opens the control valve, a large amount of water can be injected into the water injection pipe. At this time, the PLC controller starts the regulating motor, which drives the connecting rod to rotate. Since the connection between the nozzle and the water injection pipe is a corrugated connecting pipe, the connecting rod can drive the nozzle to rotate inside the crushing tank during the rotation, which can adjust the direction of the nozzle and further adjust the direction of the water flow. Moreover, by controlling the closing status of the control valve, the water flow size can be controlled, which can enhance the hydraulic effect inside the crushing tank and is beneficial to the crushing of pulp.

[0025] Please see Figures 1 to 3A pulper includes a crushing tank 1, a feed hopper 3 fixedly installed at the top of the crushing tank 1, a discharge pipe 5 connected to the bottom of the crushing tank 1, a high-efficiency crushing component inside the crushing tank 1, the high-efficiency crushing component including a rotating seat 14 rotatably installed at the bottom of the crushing tank 1, an impeller blade 12 and a cutting blade 11 fixedly installed at the bottom of the rotating seat 14, a spiral blade 10 fixedly installed at the center of the top of the rotating seat 14, a motor 6 fixedly installed at the center of the bottom of the crushing tank 1, the output end of the motor 6 being fixedly connected to the central shaft of the rotating seat 14, a filter plate 13 also being provided at the bottom of the crushing tank 1, and the central shaft of the rotating seat 14 passing through the center of the filter plate 13, and a water flow guiding component also being provided inside the crushing tank 1.

[0026] Please see Figure 3 The number of cutting blades 11 and impeller blades 12 are both 4. The cutting blades 11 and impeller blades 12 are arranged alternately, and the height of the impeller blades 12 is higher than the height of the cutting blades 11.

[0027] Please see Figure 1 A PLC controller 7 is fixedly installed at the front end of the crushing tank 1, and the PLC controller 7 is electrically connected to the motor 6.

[0028] Please see Figure 2 The tip of the spiral blade 10 extends to the top of the crushing tank 1.

[0029] In this embodiment, during use, after the motor 6 is started by the PLC controller 7, the motor 6 can drive the rotating seat 14 to rotate at high speed in the crushing tank 1. At this time, the cutting blade 11 at the bottom of the rotating seat 14 can crush the carton, and the impeller blade 12 can drive the pulp to flow continuously in the crushing tank 1, which can ensure the crushing effect of the pulp. During the rotation of the rotating seat 14, the spiral blade 10 can rotate synchronously. At this time, the spiral blade 10 can drive the pulp at the bottom of the crushing tank 1 to flow upward, which can make the pulp distribution more uniform and improve the crushing effect of the pulp.

[0030] Example 2:

[0031] Please see Figures 1 to 4 A high-efficiency hydraulic pulper with a water flow guiding structure, the water flow guiding component includes a water injection pipe 4 fixedly installed on the side wall of the crushing tank 1, a corrugated connecting pipe 15 connected to the inner side of the water injection pipe 4, a nozzle 9 fixedly connected to the other end of the corrugated connecting pipe 15, a connecting rod 8 fixedly installed at the top of the nozzle 9, and the rotation range of the nozzle 9 is between -45° and 45°.

[0032] Please see Figure 4The top of the connecting rod 8 extends to the outside of the crushing tank 1. The top of the crushing tank 1 is also fixedly installed with an adjusting motor 2 that is electrically connected to the PLC controller 7, and the output end of the adjusting motor 2 is fixedly connected to the connecting rod 8.

[0033] Please see Figure 4 The top of the water injection pipe 4 is also fixedly equipped with a control valve 16 that is electrically connected to the PLC controller 7.

[0034] In this embodiment, when the user opens the control valve 16, a large amount of water can be injected into the water injection pipe 4. At this time, the PLC controller 7 starts the regulating motor 2, which drives the connecting rod 8 to rotate. The connecting rod 8 then drives the nozzle 9 to rotate inside the crushing tank 1. Since the nozzle 9 and the water injection pipe 4 are connected by a corrugated connecting pipe 15, the connecting rod 8 can drive the nozzle 9 to rotate inside the crushing tank 1 during rotation, which can adjust the direction of the nozzle 9 and further adjust the direction of the water flow. By controlling the closing state of the control valve 16, the water flow size can be controlled, which can enhance the hydraulic effect inside the crushing tank 1 and is beneficial to the crushing of pulp.

[0035] Specifically, the corrugated connecting pipe 15 acts as a flexible connection to ensure that the nozzle 9 can rotate. The nozzle 9 can rotate horizontally inside the tank by adjusting the motor 2 and the connecting rod 8, with a rotation range between -45° and 45°.

[0036] Working Principle: First, the operator places the cardboard boxes to be processed into the crushing tank 1 from the feed hopper 3. Then, the motor 6 is started by the PLC controller 7. The motor 6 drives the rotating seat 14 to rotate at high speed inside the crushing tank 1. At this time, the cutting blade 11 at the bottom of the rotating seat 14 can crush the cardboard boxes, and the impeller blades 12 can drive the pulp to flow continuously inside the crushing tank 1, ensuring the crushing effect of the pulp. During the rotation of the rotating seat 14, the spiral blades 10 can rotate synchronously. At this time, the spiral blades 10 can drive the pulp at the bottom of the crushing tank 1 to flow upward, making the pulp distribution more uniform and improving the crushing effect of the pulp. When in use, the operator opens the control valve. After step 16, a large amount of water can be injected into the water injection pipe 4. At this time, the regulating motor 2 is started by the PLC controller 7. The regulating motor 2 can drive the connecting rod 8 to rotate. Since the nozzle 9 is connected to the water injection pipe 4 by the corrugated connecting pipe 15, the connecting rod 8 can drive the nozzle 9 to rotate in the crushing tank 1 during the rotation. The direction of the nozzle 9 can be adjusted, and the direction of the water flow can be further adjusted. By controlling the closing status of the control valve 16, the water flow size can be controlled, which can enhance the hydraulic effect in the crushing tank 1 and is conducive to the crushing of pulp. The filter plate 13 can filter the pulp and ensure the crushing quality of the pulp. The crushed pulp can be discharged and collected through the discharge pipe 5.
