[0017] Embodiment 1:

[0018] See also Figure 1 - Figure 2The utility model provides a technical solution: a lignocellulose photocatalytic pretreatment device, comprising: a stirring barrel 1; a servo motor 2, the bottom of the servo motor 2 is fixedly connected to the top of the stirring barrel 1; a feeding nozzle 3, the outer wall of the feeding nozzle 3 is fixedly connected to the inner wall of the top of the stirring barrel 1; a liquid inlet pipe 4, the outer wall of the liquid inlet pipe 4 is fixedly connected to the inner wall of the stirring barrel 1; an anti-overflow pipe 5, the outer wall of the anti-overflow pipe 5 is fixedly connected to the inner wall of the stirring barrel 1; a liquid outlet pipe 6, the outer wall of the liquid outlet pipe 6 is fixedly connected to the inner wall of the stirring barrel 1; a rotating device 7, the outer wall of the rotating device 7 is fixedly connected to the output end of the servo motor 2; a filter plate 8, the outer wall of the filter plate 8 is fixedly connected to the middle part of the inner wall of the stirring barrel 1, the rotating device 7 comprises a driving rod 71, the top of the outer wall of the driving rod 71 is fixedly connected with a scattering device 72, the middle part of the outer wall of the driving rod 71 is fixedly connected with a pushing device 73, the bottom of the outer wall of the driving rod 71 is fixedly connected with a stirring rod 74, the outer wall of the driving rod 71 is fixedly connected to the output end of the servo motor 2 The outer wall of the driving rod 71 is rotatably connected to the inner wall of the filter disc 8, and the outer wall of the driving rod 71 is rotatably connected to the inner wall of the stirring barrel 1. The cellulose is added through the feeding nozzle 3. At this time, the cellulose is in the form of large flocs and is blocked by the filter disc 8 and accumulated in the upper part of the stirring barrel 1. At this time, the servo motor 2 is started, so that the servo motor 2 drives the rotating device 7 to rotate, wherein the driving rod 71 is responsible for transmission and drives the breaking device 72 and the pushing device 73 to move. The pushing device 73 lifts the cellulose during the movement, thereby facilitating the breaking device 72 to hit the cellulose. Under the impact of the breaking device 72, the cellulose is broken up from large flocs into smaller shapes until it can pass through the filter holes on the filter disc 8, thereby falling into the lower part of the stirring barrel 1, and under the stirring of the stirring rod 74, the cellulose is soaked more fully. When the soaking is completed, the mixed photocatalytic raw materials are discharged through the liquid outlet pipe 6, thereby completing the pretreatment.

[0019] Embodiment 2:

[0020] See also Figure 1 - Figure 4The utility model provides a technical solution: on the basis of the first embodiment, the scattering device 72 includes a fixed rod 721, the inner wall of the fixed rod 721 is slidably connected with a counterweight block 723, the outer wall of the counterweight block 723 is fixedly connected with a tension spring 722, the counterweight block 723 is rotatably connected to a scattering rod 724 on the side away from the tension spring 722, the scattering rod 724 is slidably connected to a limit frame 725 at one end away from the counterweight block 723, the outer wall of the limit frame 725 is fixedly connected to the outer wall of the fixed rod 721, the end of the fixed rod 721 away from the limit frame 725 is fixedly connected to the outer wall of the driving rod 71, and the tension spring 722 One end away from the counterweight block 723 is fixedly connected to the inner wall of the fixed rod 721. When the driving rod 71 rotates rapidly, the counterweight block 723 in the breaking-up device 72 moves in a direction away from the driving rod 71 due to the centrifugal force, and pulls the tension spring 722 while moving, and squeezes the breaking-up rod 724 at the same time. Therefore, the tension spring 722 is stretched at this time, and the two breaking-up rods 724 move away from the counterweight block 723 and toward the two ends of the limit frame 725 at the same time, thereby increasing the area of ​​the breaking-up rod 724 extending out of the fixed rod 721, thereby increasing the contact area between the breaking-up device 72 and the wood cellulose.

[0021] The pushing device 73 includes a fixing sleeve 731, the outer wall of the fixing sleeve 731 is fixedly connected to the fixing frame 732, the outer wall of the fixing frame 732 is provided with an inclined groove 733, the bottom of the fixing frame 732 is fixedly connected to an inclined plate 734, and a rotating plate 735 is arranged above the inclined plate 734. The inner wall of the fixing sleeve 731 and the inner wall of the fixing frame 732 are both rotatably connected to the outer wall of the rotating plate 735, the inner wall of the fixing sleeve 731 is fixedly connected to the outer wall of the driving rod 71, and the rotating fixing frame 732 is rotated through the inclined groove. The inclined surface of 733 sweeps the wood cellulose onto the filter disc 8, and the inclined plate 734 at the bottom of the fixing frame 732 spreads the wood cellulose on the filter disc 8. When the wood cellulose is broken up into a size that can pass through the filter disc 8, it will pass more easily under the push of the inclined plate 734, and the unbroken wood cellulose will hit the rotating plate 735. The rotating plate 735 will rotate after encountering resistance and lift up large pieces of wood cellulose again during rotation, making it easier for the breaking device 72 to break it up.

[0022] Working principle:

[0023] When in use, cellulose is added through the feed nozzle 3. At this time, the cellulose is in the form of large flocs and is blocked by the filter disc 8 and accumulated in the upper part of the mixing barrel 1. At this time, the servo motor 2 is started, so that the servo motor 2 drives the rotating device 7 to rotate, wherein the driving rod 71 is responsible for transmission and drives the dispersing device 72 and the pushing device 73 to move. The pushing device 73 lifts the cellulose during the movement, thereby facilitating the dispersing device 72 to hit the cellulose. Under the impact of the dispersing device 72, the cellulose is broken up from large flocs into smaller shapes until it can pass through the filter holes on the filter disc 8 and fall into the lower part of the mixing barrel 1. When the servo motor 2 is started, the liquid medicine is fed in through the liquid inlet pipe 4, and an anti-overflow pipe 5 is provided to prevent the liquid medicine level from being too high and affecting the upper part of the mixing barrel 1. Under the stirring of the stirring rod 74, the cellulose is more fully soaked. When the soaking is completed, the mixed photocatalytic raw materials are discharged through the liquid outlet pipe 6, thereby completing the pretreatment, saving the process of transferring materials for the experimenter, thereby saving the experiment time.

[0024] The breaking device 72 is provided to break up the large flocculent wood cellulose. When the wood cellulose agglomerates are large, the servo motor 2 is set to have a larger working power, so that the driving rod 71 rotates faster. Under the rapid rotation of the driving rod 71, the counterweight block 723 in the breaking device 72 moves in a direction away from the driving rod 71 due to the centrifugal effect, and pulls the tension spring 722 while moving, and squeezes the breaking rod 724 at the same time, so that the tension spring 722 is stretched at this time, and the two breaking rods 724 move away from the counterweight block 723 and toward the two ends of the limit frame 725 at the same time, thereby increasing the area of ​​the breaking rod 724 extending out of the fixed rod 721, thereby increasing the contact area between the breaking device 72 and the wood cellulose, making the wood cellulose easier to be broken up.

[0025] The fixed sleeve 731 of the pushing device 73 rotates along with the driving rod 71, and the fixed sleeve 731 rotates while driving the fixed frame 732 to rotate. Since the mixing barrel 1 is provided with a conical side wall in order to guide the wood cellulose, the conical side wall is easier to accumulate the wood cellulose than the vertical side wall. At this time, the rotating fixed frame 732 sweeps the wood cellulose onto the filter disc 8 through the inclined surface of the inclined groove 733, and the inclined plate 734 at the bottom of the fixed frame 732 spreads the wood cellulose on the filter disc 8. When the wood cellulose is broken up to a size that can pass through the filter disc 8, it will be easier to pass through under the push of the inclined plate 734, and the wood cellulose that has not been broken up will hit the rotating plate 735. The rotating plate 735 will rotate after encountering resistance, and will lift up large pieces of wood cellulose again when rotating, so as to facilitate the breaking up of the breaking device 72.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
