Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic pulping, and in particular to a hydraulic pulping device. Background Art

[0002] In the paper industry, hydraulic pulpers are one of the most commonly used pulping equipment in the pulp and paper industry. They are mainly used to pulp waste books, waste cardboard boxes and other waste items. In the recycling process, waste paper, old newspapers or other waste paper products must be repulped to ensure the normal operation of subsequent production equipment and the purity of the finished product.

[0003] In existing hydraulic pulping devices, such as the hydraulic pulping device disclosed in utility model patent application number 202020321048.3, the driving component drives the cover plate to rotate clockwise, and the rotating component drives the stirring shaft to rotate counterclockwise. Therefore, during use, the shredded paper in the pulp can generate more collisions, rather than simply rotating with the stirring shaft, thus resulting in a better pulping effect.

[0004] However, during the pulping process of a hydraulic pulper, paper fibers in waste paper will adhere to and become entangled on the mixing shaft. Over time, this will reduce the pulverizing effect, and the equipment will also have difficulty discharging the material. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a hydraulic pulping device that reduces the entanglement of paper fibers on the blades and prevents residual material from sticking to the wall during the pulping process of a hydraulic pulper by setting up a rinsing mechanism and a scraping mechanism.

[0006] The present invention relates to a hydraulic pulping device, which includes a material storage mechanism; it also includes a crushing mechanism, multiple sets of reverse cutting mechanisms, a scraping mechanism and a rinsing mechanism. The crushing mechanism is installed on the material storage mechanism, the multiple sets of reverse cutting mechanisms are installed on the crushing mechanism, the scraping mechanism is installed on the material storage mechanism, and the rinsing mechanism is installed at the lower end of the material storage mechanism.

[0007] The material storage mechanism stores the material, the crushing mechanism crushes the material, the reverse cutting mechanism reverses the cutting, the scraping mechanism scrapes the material, and the rinsing mechanism rinses the material. The material storage mechanism stores the shredded paper, the crushing mechanism crushes the shredded paper, the reverse cutting mechanism reverses the cutting, and the scraping mechanism makes the pulp tumble and crush more evenly. During the crushing process, the rinsing mechanism can be opened at any time to humidify the material and rinse the inside of the device. This reduces the entanglement of paper fibers on the blades and prevents residual material from sticking to the wall during the pulping process of the hydraulic pulper.

[0008] Preferably, the material storage mechanism includes a storage hopper, a discharge channel, and a flow guide hood. The discharge channel is installed at the lower end of the storage hopper, and the flow guide hood is installed inside the storage hopper. The material is stored through the storage hopper, and the shredded paper is guided by the flow guide hood and discharged through the discharge channel.

[0009] Preferably, the pulverizing mechanism includes a cylinder, a rotating shaft, a motor, multiple sets of main gears, multiple sets of cutter wheels, and multiple sets of driven gears. The cylinder is mounted on the upper end of the guide shroud. The rotating shaft is rotatably mounted on the storage hopper and is located inside the cylinder. The input end of the rotating shaft extends to the upper side of the storage hopper. The motor is mounted on the upper end of the storage hopper, and the output end of the motor is connected to the input end of the rotating shaft. Multiple sets of main gears are mounted on the rotating shaft. Multiple sets of cutter wheels are rotatably mounted on the cylinder, and each set of cutter wheels is equipped with a set of toothed rings and a set of bevel gear rings. Multiple sets of driven gears are rotatably mounted inside the cylinder, and each set of driven gears meshes with a set of main gears and a set of toothed rings on the cutter wheels. By turning on the motor, the rotating shaft is driven to rotate. The rotation of the rotating shaft drives the main gears to rotate. The rotation of the main gears meshes with the driven gears, driving the cutter wheels to rotate and pulverize the pulp.

[0010] Preferably, the reverse cutting mechanism includes a second cutter wheel and a bevel gear. The second cutter wheel is rotatably mounted on the equipment cylinder, and a set of bevel gear rings are provided on the second cutter wheel. The bevel gears are rotatably mounted on the equipment cylinder, and the bevel gears mesh with the bevel gear rings on the second cutter wheel and the first cutter wheel. By rotating the first cutter wheel and meshing with the bevel gears, the bevel gears mesh with the second cutter wheel, causing the second cutter wheel to reverse and crush the pulp.

[0011] Preferably, the scraping mechanism includes a rotating frame, a spiral scraper, a main bevel gear, and a bevel gear shaft. The rotating frame is rotatably installed inside the storage hopper, and a bevel gear ring is provided on the rotating frame. The spiral scraper is installed on the rotating frame, the main bevel gear is installed on the rotating shaft, and the bevel gear shaft is rotatably installed on the storage hopper. The bevel gear shaft meshes with the main bevel gear, and the bevel gear shaft meshes with the bevel gear ring on the rotating frame. The rotating shaft drives the main bevel gear to rotate, and the meshing of the main bevel gear with the bevel gear shaft causes the bevel gear shaft to rotate. At the same time, the rotation of the bevel gear shaft meshes with the bevel gear ring on the rotating frame, causing the rotating frame to drive the spiral scraper to rotate and scrape the inner wall of the storage hopper, while also causing the pulp to tumble up and down.

[0012] Preferably, the rinsing mechanism includes a water tank, a pump, a nozzle, and a conduit. The water tank is installed at the lower end of the storage hopper, the pump is installed at the lower end of the water tank, and the pump input extends into the water tank. The nozzle is installed on the storage hopper, and the pump output and the nozzle input are connected through a conduit. The storage hopper is rinsed and replenished with water by opening the pump and the conduit in conjunction with the nozzle.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the shredded paper is stored by the material storage mechanism, the shredded paper is crushed by opening the crushing mechanism, and the reverse cutting mechanism is used for reverse cutting. At the same time, the scraping mechanism makes the pulp turn over and crush more evenly. During the crushing process, the rinsing mechanism can be opened at any time to humidify and rinse the inside of the device. Thus, during the pulping process of the hydraulic pulper, the paper fibers are reduced from wrapping around the blades and the remaining material is prevented from sticking to the wall.
