Description

Technical Field

[0001] The utility model relates to the technical field of refiners, in particular to a refiner for papermaking and pulping. Background Art

[0002] The pulping machine is a novel stainless steel wet grinding equipment, which is used for wet grinding of grain materials such as rice, soybeans, corn, potatoes, etc., and also for wet grinding of certain materials in industries such as medicine, sugar making, and food. After the materials are cleaned, soaked, and pre-treated, they enter the hopper and enter the grinding machine. Under the action of centrifugal force, they enter between the upper and lower sand plates in relative motion. Due to the combined effects of mutual impact and extrusion of the materials and shearing and tearing of the sand plates, the materials are ground from inside to outside and from coarse to fine along the plane of the sand plate.

[0003] Existing paper pulping refiners, such as a paper pulping refiner disclosed in Chinese patent application CN219547411 U, record: by conveying the pulping material from the feed funnel to the inside of the pulping cylinder and falling onto the screen plate, the driving motor drives the rotating rod, and the rotation of the rotating rod drives the crushing blade to rotate, so that the pulping material can be crushed. At this time, the crushed material falls on the second grinding ring and the conical block, and the material on the conical block will slide onto the second grinding ring. The rotation of the rotating rod drives the cylinder to rotate through the conical block and the connecting plate, and the rotation of the cylinder drives the second grinding ring to rotate, which can grind the crushed material. At this time, the ground material will slide onto the filter screen through the triangular ring plate, and part of the material will pass through the filter screen for discharge. At this time, the rotating rod drives the spiral blade to rotate, and the rotation of the spiral blade drives another part of the material to spirally rise for grinding again.

[0004] During use of the above-mentioned paper pulping refiner, the pulping material is transported from the feed funnel to the inside of the refining cylinder, and the crushing blade on the rotating rod is driven by the driving motor to rotate, so that the pulping material can be crushed. The rotation of the cylinder drives the second grinding ring to rotate, so that the crushed material can be ground. The ground material is powdery, and the powdery material usually contains many fine particles. When these particles pass through the filter plate, they are small in size and adhere to each other on the surface, which makes it difficult for the material to pass through the filter plate quickly, affecting the production rate of paper pulping. In addition, during the refining process, the fibers in some materials cannot be completely dispersed and broken up, and are easily accumulated on the filter screen, resulting in accumulation of impurities. If the filter plate is not cleaned and maintained in time, it will affect the smoothness of the new material passing through the filter plate, resulting in material accumulation or slow passage.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model is further described below in conjunction with embodiments.

[0025] Example 1

[0026] Reference Figure 1-3 , which is the first embodiment of the utility model, provides a pulping machine for papermaking pulping, including a pulping cylinder 100, on which a filter screen shaking disassembly mechanism 200 is installed, the filter screen shaking disassembly mechanism 200 includes a discharge cylinder 201 installed on the lower surface of the pulping cylinder 100, a support frame 202 is connected to the discharge cylinder 201, a spring piece 203 is sleeved on the support frame 202, a filter screen 204 is slidably connected to the discharge cylinder 201, a protrusion 205 is fixedly connected to the upper surface of the filter screen 204, and the filter screen 204 is The upper surface is slidably connected with a sliding column 206, which drives the sliding column 206 on the lower surface to rotate counterclockwise along the upper surface of the filter screen 204 through the rotation of the rotating plate 207. When the sliding column 206 slides to the protrusion 205 on the filter screen 204, it pushes the filter screen 204 to slide downward along the discharge barrel 201. After the sliding column 206 passes the protrusion 205, the compressed spring piece 203 exerts a force to push the filter screen 204 to rebound and shake quickly along the discharge barrel 201, thereby increasing the discharge rate of the material on the filter screen 204.

[0027] The upper surface of the sliding column 206 is connected to a rotating plate 207 , and the upper surface of the rotating plate 207 is connected to a rotating rod 208 . The rotating rod 208 and the rotating plate 207 are driven to rotate by the output end of the motor 210 .

[0028] A motor 210 is sleeved on one end of the rotating rod 208 away from the rotating plate 207, and a spiral blade 209 is sleeved on the rotating rod 208. The spiral blade 209 is driven by the rotating rod 208 to rotate, so that the fallen materials are lifted up and ground again.

[0029] During use, the rotating plate 207 rotates to drive the sliding column 206 on the lower surface to rotate counterclockwise along the upper surface of the filter screen 204. When the sliding column 206 slides to the protrusion 205 on the filter screen 204, the filter screen 204 is pushed to slide downward along the discharge barrel 201. After the sliding column 206 passes the protrusion 205, the compressed spring piece 203 exerts a force to push the filter screen 204 to rebound and shake quickly along the discharge barrel 201. The shaking of the filter screen 204 can accelerate the discharge speed of the pulp in the pulper, thereby improving production efficiency and reducing the production cycle.

[0030] Example 2

[0031] Reference Figure 1-4 , which is the second embodiment of the utility model, provides a pulping machine for papermaking, including a filter screen 204 connected to two sliding columns 211 on both sides, and a lifting slide groove 212 is opened on both sides of the discharge barrel 201 corresponding to the two sliding columns 211. The two sliding columns 211 on both sides of the filter screen 204 slide in the lifting slide grooves 212 on both sides of the discharge barrel 201, thereby limiting the filter screen 204.

[0032] A rotating slot 213 is provided on the discharge barrel 201, and a limiting slot 214 is provided on the discharge barrel 201. By pushing the protrusion 205, the filter screen 204 is driven to rotate clockwise, so that the slide column 211 slides from the lifting slot 212 along the rotating slot 213 to the limiting slot 214, which is convenient for cleaning and replacing the filter screen 204.

[0033] A threaded sleeve 215 is fixedly connected to the lower surface of the refining cylinder 100, and a discharge cylinder 201 is threadedly connected inside the threaded sleeve 215. The discharge cylinder 201 can be removed from the threaded sleeve 215 on the refining cylinder 100 by rotating it. When the discharge cylinder 201 is installed on the threaded sleeve 215, the lower surface of the refining cylinder 100 will block the limiting groove 214 on the discharge cylinder 201, thereby playing a limiting role and preventing the filter screen 204 from falling off from the discharge cylinder 201.

[0034] During use, the discharge barrel 201 can be removed from the threaded sleeve 215 on the pulping barrel 100 by rotating it, and the filter screen 204 is driven to rotate clockwise by pushing the protrusion 205, so that the slide column 211 slides from the lifting slide groove 212 along the rotating slide groove 213 to the limiting slide groove 214, which is convenient for cleaning or replacing the filter screen 204. It can make it easier and faster for maintenance personnel to clean or replace the filter screen 204, reduce equipment downtime, and improve production efficiency.
