Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste paper recycling, and particularly relates to a water circulation treatment equipment for waste paper recycling. BACKGROUND

[0002] Waste paper refers to recyclable resources discarded after use in production and life, including various high-grade paper, yellow board paper, waste paper box, edge paper, packing paper, enterprise paper, engineering paper, books and newspapers, etc.

[0003] In the existing waste paper recycling process, a large amount of wastewater is generated. In order to avoid waste of water resources, the wastewater needs to be treated to meet the use requirements and then be reused, so as to achieve the purpose of saving water. The concentrated paper pulp is transported to a paper machine to form a wet paper sheet on a net part (such as a long net or a round net). A large amount of water will be filtered out through the mesh to form "white water" in the process. At the same time, a small amount of wastewater will be generated when the wet paper sheet is pressed and dewatered. This kind of wastewater is low-concentration wastewater, mainly containing very fine fibers and a small amount of dissolved salt, with a COD value of <800 mg / L, clear water quality and low suspended solids content. Therefore, the water quality is good and is the main water source for recycling. However, in the existing equipment, the wastewater is mainly filtered through a filter screen to achieve the interception of impurities in the wastewater. In order to avoid the fact that the fine impurities and tiny impurities in the wastewater cannot be cleaned, the treated wastewater cannot meet the use requirements and needs to be subjected to membrane filtration in other equipment to achieve fine filtration, and then chemical drugs are added for stirring treatment. In the above process, different equipment is needed for preliminary filtration and fine filtration, which will cause the wastewater filtration time to be relatively long, thereby affecting the wastewater filtration efficiency, and the addition of chemical drugs for treatment is easy to cause excessive or insufficient addition, thereby hindering the treatment of the wastewater.

[0034] After a period of use, the user moves the movable plate 9 to the left out of the hollow frame by pulling the handle 10. Then, the sand and gravel filter layer 12 is replaced. The movement of the movable plate 9 is achieved by the second rack and pinion 30 driving the spur gear 29 to rotate clockwise once. The clockwise rotation of the spur gear 29, through its one-way bearing, causes the rotating rod 24 to rotate clockwise. The clockwise rotation of the rotating rod 24 drives the ratchet 25 and the lower pulley 27 to rotate clockwise. This, in turn, causes the upper pulley 27 to rotate via the conveyor belt 28. 7. Rotating clockwise causes the upper pulley 27 to rotate clockwise, which in turn rotates the shaft 16. This rotation of the shaft 16, via the first gear 19, drives the first rack frame 20, moving the discharge frame 21 to the left. The spring on the spring extension rod 22 is compressed, and simultaneously, the clockwise rotation of the shaft 16 causes the discharge shell 17 and its cleaning shell 18 to move clockwise circumferentially. This clockwise circumferential movement of the cleaning shell 18 cleans the debris trapped by the filter screen 14, placing it within the filter screen. When the shell 18 rotates 90° clockwise, the discharge frame 21 moves to the lower side of the discharge port of the discharge shell 17. When the cleaning shell 18 rotates 180° clockwise and is directly above, the discharge frame 21 continues to move, and the debris inside the cleaning shell 18 slides down through the discharge shell 17 into the discharge frame 21. Because the discharge frame 21 is inclined, the debris inside the discharge frame 21 slides down its inclined surface and is discharged. When the cleaning shell 18 rotates 270° clockwise, the first missing gear 19 does not... The first rack frame 20 is re-engaged, and the discharge frame 21 moves to the right and resets under the elastic force of the spring telescopic rod 22. When the cleaning shell 18 rotates 360° clockwise, the first rack frame 20 and the first missing gear 19 return to their initial meshing state, opening space for the cleaning shell 18 to continue rotating. During the resetting process of the second rack frame 30, it meshes with the spur gear 29 and rotates counterclockwise. The counterclockwise rotation of the spur gear 29 cannot drive the rotating rod 24 to rotate counterclockwise through the one-way bearing on it. Example 2

[0035] Based on Example 1, such as Figure 2 , 3 As shown in Figure 10, a mounting bracket 45 is fixedly connected between the inner sides of the three support legs 2. The mounting bracket 45 is embedded in the piston housing 46. An air inlet pipe is connected to the top of the piston housing 46. A one-way valve is provided on the air inlet pipe. A piston plate 47 is slidably connected inside the piston housing 46. A third spring 48 is fixedly connected between the top of the piston plate 47 and the piston housing 46. A connecting rod 49 that penetrates the top of the piston housing 46 is fixedly connected to the top of the piston plate 47. A contact block 50 is fixedly connected to the upper end of the connecting rod 49. A pressing block 55 is fixedly connected to the bottom of the transmission gear 7 on one side. An air jet is provided at the bottom of the mixing tank 1. The air jet is connected to the piston housing 46.

[0036] The air jet comprises two arc-shaped shells 51 fixed to the bottom of the stirring box 1, the top of the arc-shaped shells 51 is fixed with a nozzle 52 penetrating the stirring box 1, a communication pipe 53 is communicated between the two arc-shaped shells 51, a connecting pipe 54 is communicated between the communication pipe 53 and the piston shell 46, and a one-way valve is arranged on the connecting pipe 54.

[0037] The rotation of the transmission gear 7 enables the circumferential movement of the extrusion block 55, the circumferential movement of the extrusion block 55 extrudes the contact block 50 to move the connecting rod 49 downward, the downward movement of the connecting rod 49 drives the piston plate 47 to move downward, the third spring 48 is stretched accordingly, and air can be introduced through the air inlet pipe on the piston shell 46. When the extrusion block 55 moves away from the contact block 50, the piston plate 47 can move upward under the elastic force of the third spring 48, the upward movement of the piston plate 47 enables the air in the piston shell 46 to enter the arc-shaped shell 51 through the connecting pipe 54 and the communication pipe 53, and the gas in the arc-shaped shell 51 is sprayed through the nozzle 52. Therefore, air bubbles can be formed in the stirring box 1, and the upward floating of the air bubbles can avoid the chemical medicine from depositing at the bottom of the stirring box 1, thereby affecting the full melting of the chemical medicine.
