[0026] Example

[0027] Please see Figures 1 to 6 This utility model provides a technical solution for a cold water circulation energy-saving device for cellulose production, including a waste heat recovery box 1 and a filter box 2. A first protective box is installed on the top of the filter box 2. A first motor 3 is installed inside the first protective box. A first rotating shaft 4 is installed at the output end of the first motor 3. A rotating plate is welded to the outer surface of the first rotating shaft 4. A second rotating shaft 5 is rotatably connected to the inside of the rotating plate via bearings. A first gear 28 is installed on the top of the second rotating shaft 5. A first through hole is opened inside the left wall of the waste heat recovery box 1. A three-way pipe 6 adapted to the inner diameter of the first through hole is installed in the first through hole. The filter box 2 is equipped with a spiral blade 7. The front and rear inner walls of the filter box 2 are provided with a first slot, a second slot and a third slot. The first slot, the second slot and the third slot are respectively fitted with a first filter screen 8, a second filter screen 9 and an activated carbon plate 10. The top of the filter box 2 is provided with a second protective box. The second protective box is equipped with a second motor 11. The output end of the second motor 11 is provided with a third rotating shaft 12. The outer surface of the third rotating shaft 12 is provided with a shaped plate 13. The inside of the shaped plate 13 is rotatably connected to a fourth rotating shaft 14 through a bearing. The outer surface of the fourth rotating shaft 14 is welded with a ball 15.

[0028] Specifically, the inner top wall of the waste heat recovery box 1 is provided with a second gear 16, and the first gear 28 meshes with the second gear 16. The outer surfaces of the first rotating shaft 4 and the second rotating shaft 5 are provided with first swivel blades 17. The number of first swivel blades 17 is several and they are evenly distributed on the outer surfaces of the first rotating shaft 4 and the second rotating shaft 5.

[0029] Please refer to Figure 1 to Figure 2The second gear 16 meshes with the first gear 28 and rotates, driving the first gear 28, so that the second shaft 5 drives the hinge blade to rotate around the axis of the first shaft 4 while rotating around the axis of the second shaft 5 itself.

[0030] Specifically, a water inlet pipe is installed at the top of the waste heat recovery box 1, and a first drain pipe is installed at the bottom of the waste heat recovery box 1. A first control valve is installed in both the water inlet pipe and the first drain pipe.

[0031] Please see Figures 1 to 2 Once the water temperature in the waste heat recovery tank 1 reaches a certain stable level, it is discharged through the first drain pipe, and new clean water is injected into the waste heat recovery tank 1 through the inlet pipe.

[0032] Specifically, the other two ends of the three-way pipe 6 are located inside the filter box 2. A second through hole is opened inside the top wall of the filter box 2. A support rod 18 adapted to the inner diameter of the second through hole is installed in the second through hole. A cleaning brush 19 is threadedly connected to the outer surface of the support rod 18 near the bottom.

[0033] Please see Figures 2 to 3 When circulating water enters the filter box 2 through the three-way pipe 6, the first filter screen 8, the second filter screen 9 and the activated carbon plate 10 filter the circulating water respectively, filtering out impurities such as fiber debris and sand, removing dissolved organic matter, residual chlorine and odors. When cleaning the impurities on the surface of the filter screen, the support rod 18 is pulled up and down, and the support rod 18 drives the cleaning brush 19 to move up and down to clean the impurities on the surface of the filter screen.

[0034] Specifically, the inner top wall of the filter box 2 is provided with a partition, a second drain pipe 20 is provided on the left side of the partition, a second control valve is provided in the second drain pipe 20, a third drain pipe 21 is provided on the rear side of the filter box 2, and a protective cover is threaded onto the outer surface of the third drain pipe 21.

[0035] Please see Figures 4 to 5 The partition separates the filter box 2 to facilitate the softening and sterilization of the circulating water after filtration. After the impurities on the surfaces of the first filter screen 8 and the second filter screen 9 are cleaned, the cleaned impurities can be discharged through the third drain pipe 21.

[0036] Specifically, a support plate is provided on the rear inner side wall of the filter box 2, and a ball groove is opened inside the support plate. The ball 15 is snapped into the ball groove. A second hinge blade 22 is provided on the outer surface of the fourth rotating shaft 14. A medicine inlet pipe 23 is provided on the top of the filter box 2. A fourth drain pipe 24 is provided on the right side of the filter box 2. A third control valve is provided in the fourth drain pipe 24.

[0037] Please refer to Figure 4 to Figure 5The ball 15 can rotate in the ball tank. The agent is added to the filter box 2 through the inlet pipe 23. The second blade 22 stirs the circulating water to make the agent fully stirred in the circulating water, thereby improving the efficiency of softening and sterilization. The circulating water after filtration, softening and sterilization is discharged through the fourth drain pipe 24.

[0038] Specifically, a third gear 25 is provided at one end of the fourth rotating shaft 14, and a fourth gear 26 is provided on the inner top wall of the filter box 2. The fourth gear 26 meshes with the third gear 25.

[0039] Please refer to Figure 4 to Figure 5 The third gear 25 meshes with the fourth gear 26, causing the fourth shaft 14 to rotate around its own axis while rotating around the axis of the third shaft 12, thus fully agitating the circulating water and the chemicals.

[0040] Specifically, a Π-shaped groove is provided inside the top wall of the filter box 2, and a push rod 27 is engaged in the Π-shaped groove. The first filter screen 8, the second filter screen 9, and the activated carbon plate 10 are all provided with a third through hole near the top. The inner diameter of the third through hole is slightly larger than the diameter of the push rod 27.

[0041] Please refer to Figure 5 to Figure 6 When replacing the first filter screen 8, the second filter screen 9, and the activated carbon plate 10, first rotate the push rod 27 90°, then push the push rod 27 so that the push rod 27 disengages from the third through hole inside the first filter screen 8, the second filter screen 9, and the activated carbon plate 10. The push rod 27 no longer limits the first filter screen 8, the second filter screen 9, and the activated carbon plate 10. Pull the first filter screen 8, the second filter screen 9, and the activated carbon plate 10 upward so that the first filter screen 8, the second filter screen 9, and the activated carbon plate 10 disengage from the slot for replacement.

[0042] During operation, circulating water enters the three-way pipe 6. The spiral blades 7 inside the three-way pipe 6 increase the travel distance of the circulating water, allowing the residual heat inside the circulating water to be transferred to the clean water through the three-way pipe 6. During the heat transfer process, the output end of the first motor 3 drives the first rotating shaft 4 to rotate. The first rotating shaft 4 drives the rotating plate, the first auger blade 17 set on the outer surface of the first rotating shaft 4, and the second rotating shaft 5 to rotate, thus stirring the clean water. At the same time, the second rotating shaft 5 drives the first auger blade 17 and the first gear 28 set on the outer surface of the second rotating shaft 5 to rotate. The first gear 28 meshes with the second gear 16, causing the first gear 28 to drive the second gear 16 to rotate. Rotating shaft 5 causes the first auger 17 to rotate around the axis of the first shaft 4 while simultaneously rotating around its own axis, thoroughly agitating the water and forcing a mixed flow to ensure uniform water temperature distribution. This prevents the "hot layer" from isolating from the "cold layer," improving heat transfer efficiency. The circulating water after heat transfer enters filter box 2, where it passes through the first filter screen 8, the second filter screen 9, and the activated carbon plate 10. This filters out fiber debris, sand, and other impurities, removes dissolved organic matter, residual chlorine, and odors. After filtration, the second control valve is opened, allowing the circulating water to flow freely. Entering the right side of the partition, the reagent enters the filter box 2 through the inlet pipe 23. The output end of the second motor 11 drives the third rotating shaft 12 and the shaped plate 13 to rotate. The shaped plate 13 drives the fourth rotating shaft 14, the third gear 25, and the second auger 22 to rotate, stirring the circulating water and reagent. At the same time, the third gear 25 meshes with the fourth gear 26, causing the third gear 25 to drive the third rotating shaft 12, the ball 15, and the second auger 22 to rotate in the ball groove, fully stirring the circulating water and reagent. When it is necessary to clean the impurities on the surface of the first filter screen 8 and the second filter screen 9, the support rod 18 is pulled up and down, and the support rod 18 drives... The cleaning brush 19 moves up and down to clean impurities from the surface of the filter screen. The cleaned impurities can be discharged through the third drain pipe 21. When replacing the first filter screen 8, the second filter screen 9, and the activated carbon plate 10, first rotate the push rod 27 90°, then push the push rod 27 so that the push rod 27 disengages from the third through hole inside the first filter screen 8, the second filter screen 9, and the activated carbon plate 10. The push rod 27 no longer limits the first filter screen 8, the second filter screen 9, and the activated carbon plate 10. Pull the first filter screen 8, the second filter screen 9, and the activated carbon plate 10 upward so that the first filter screen 8, the second filter screen 9, and the activated carbon plate 10 disengage from the slot for replacement.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
