Description

Technical Field

[0001] This utility model relates to the field of pulp hydraulic pulping technology, and in particular to a pulp hydraulic pulping machine with high cracking efficiency. Background Technology

[0002] Pulp is a fibrous material made from plant fibers through various processing methods. It can be categorized according to the processing method.

[0003] Pulp can be classified into mechanical pulp, chemical pulp, and chemimechanical pulp. It can also be classified according to the fiber raw materials used, such as wood pulp, straw pulp, hemp pulp, reed pulp, sugarcane pulp, bamboo pulp, and rag pulp. Furthermore, it can be classified according to different purities, such as refined pulp, bleached pulp, unbleached pulp, high-yield pulp, and semi-chemical pulp. It is generally used to manufacture paper and paperboard. In current technology, virgin wood paper or waste paper needs to be crushed by a hydraulic shredder and then refined by a pulper to achieve the required beating degree and fiber length.

[0004] Current pulp hydraulic pulpers are usually used in conjunction with pulping wheels to pulp more efficiently through the rotation of the pulping wheels. While this can improve the pulping efficiency of the device, it does not take into account that there are certain dead zones when the pulping wheels rotate, which can cause some pulp to not be fully broken down, thus affecting the overall efficiency.

[0005] Therefore, a high-efficiency pulp hydraulic pulper is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a pulp hydraulic pulper with high cracking efficiency, which can solve the problem of certain dead zones in the Fugger device.

One end of the connecting rod passes through the annular through groove, passes through the baffle, and extends into the interior of the transmission box where the second transmission gear is fixedly mounted. The second transmission gear meshes with the first transmission gear.

[0009] Preferably, a guide frame is fixedly installed on the top of the pretreatment box, and a guide pipe is fixedly installed on the bottom of the pretreatment box. One end of the guide pipe communicates with the interior of the pretreatment box, and the other end of the pretreatment box communicates with the interior of the pulping box.

[0010] Preferably, the inner wall of the pulping box is fixedly installed with multiple sets of pulping blocks in a ring-shaped distribution.

[0011] Preferably, an inlet pipe is fixedly installed on the top of the water tank, a water pump is fixedly installed on the bottom inner side of the water tank, and a conduit is fixedly installed at the output end of the water pump, with one end of the conduit communicating with the interior of the pulping tank.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a high-efficiency pulp hydraulic pulper, including a pulping box 1. A water tank 5 is fixedly installed on the front side of the pulping box 1. Four sets of support legs 3 are fixedly installed on the bottom of the pulping box 1 in a ring distribution. A transmission box 2 is fixedly installed on the top of the pulping box 1. A pretreatment box 7 is fixedly installed on the rear side of the pulping box 1. A pulping mechanism 8 is provided on the pulping box 1. The pulping mechanism 8 includes a first motor 801 fixedly installed on the bottom of the pulping box 1. The pulping mechanism 8 also includes a mounting frame 802, pulping wheels 803, a first transmission gear 804, a baffle 805, a connecting rod 806, and a second transmission gear 807. This allows the device to start by controlling the first motor 801, and simultaneously control the two sets of pulping wheels 803 to rotate and revolve, thereby agitating the water flow to rotate at multiple angles. This allows the device to pulp in all directions, reducing the dead zone range of the device and improving the pulping efficiency.

[0025] like Figure 1 and Figure 2 As shown, multiple sets of pulp blocks 10 are fixedly installed on the inner wall of the pulping tank 1 in a ring-shaped distribution. A water inlet pipe 6 is fixedly installed on the top of the water tank 5. A water pump 13 is fixedly installed on the bottom inner side of the water tank 5. A conduit 14 is fixedly installed at the output end of the water pump 13. One end of the conduit 14 communicates with the interior of the pulping tank 1. A discharge pipe 4 is fixedly installed on the front side of the pulping tank 1. A valve is installed on the discharge pipe 4. When the pulp raw material rotates, it will come into contact with the pulp blocks 10 on the inner wall of the pulping tank 1, so that the pulp blocks 10 can further improve the breaking efficiency of the device and improve the practicality of the device.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, a guide frame 9 is fixedly installed on the top of the pretreatment box 7, and a guide pipe 12 is fixedly installed on the bottom of the pretreatment box 7. One end of the guide pipe 12 communicates with the interior of the pretreatment box 7, and the other end of the pretreatment box 7 communicates with the interior of the pulping box 1. Two sets of crushing wheels 11 are rotatably installed inside the pretreatment box 7, distributed left and right, and the two sets of crushing wheels 11 mesh with each other. A second motor 15 is fixedly installed on the rear side of the pretreatment box 7. The output end of the second motor 15 extends into the interior of the pretreatment box 7 and is fixedly connected to the crushing wheels 11. This allows the device to start by controlling the second motor 15 and drive the two sets of crushing wheels 11 to rotate, so that the crushing wheels 11 can pre-crush the pulp raw materials, thereby further improving the crushing efficiency of the device and improving the practicality of the device.

[0027] Working principle: During use, the pulp raw material is placed in the pretreatment box 7. The second motor 15 is started, driving the crushing wheel 11 to rotate. Because the two sets of crushing wheels 11 are meshed, one set drives the other to rotate, thus crushing the pulp raw material. The crushed pulp raw material enters the pulping box 1 through the feed pipe 12. The first motor 801 is started, driving the mounting frame 802 to rotate, which in turn drives the pulping wheel 803 to revolve. The connecting rod 806 allows the pulping wheel 803 to drive the second transmission gear 807 to rotate. The second transmission gear 807 meshes with the first transmission gear 804. The combined configuration allows the second transmission gear 807 to rotate, which in turn drives the connecting rod 806 to rotate, thereby causing the pulping wheel 803 to rotate. The multiple rotations of the pulping wheel 803 improve the pulping of the raw material inside the pulping box 1. Water is injected into the water tank 5 through the water inlet pipe 6, and the water pump 13 draws the water from the water tank 5 into the conduit 14, which sprays the raw material inside the pulping box 1. The impact force of the water flow causes the raw material to rotate. When the raw material rotates, it comes into contact with the pulp blocks 10 on the inner wall of the pulping box 1, which further improves the pulping efficiency of the device. After pulping, the pulp can be discharged from the discharge pipe 4 by opening the valve on the discharge pipe 4.

[0028] 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.
