Description

TECHNICAL FIELD

[0001] The utility model relates to the field of pulping waste water, and specifically to a waste paper pulping waste water recovery device. BACKGROUND

[0002] Pulping waste water refers to waste water generated in the pulping process, mainly from chemical pulping and mechanical pulping processes.

[0003] In the prior art, the pulping and papermaking industry is an industry with large water consumption and serious pollution. The waste water contains a large amount of organic matter, inorganic matter and suspended solids. If it is directly discharged without treatment, it will cause serious pollution to the water body. The papermaking waste water treatment device is a commonly used device in the process of papermaking waste water treatment. The papermaking waste water treatment device in the related art usually comprises a shell and a filtering structure. The filtering structure is installed inside the shell. The top wall of the shell is usually connected with a water inlet channel. When in use, water is introduced into the shell through the water inlet channel to filter the waste water.

[0004] However, the pulping waste water contains a large amount of suspended solids, which can easily block the filter holes when the waste water is filtered, thereby affecting the passage of the waste water and reducing the efficiency of the pulping waste water recovery. TECHNICAL SOLUTION

[0005] The utility model aims at providing a waste paper pulping waste water recovery device to solve the problems in the above background art.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a waste paper pulping waste water recovery device, which comprises:

[0007] A filter bin is internally fixed with a first filter plate. The upper surface of the first filter plate is fixed with a vortex block. The inner wall of the filter bin below the first filter plate is movably provided with a second filter plate. The side surface of the second filter plate is fixed with a push rod.

[0008] A top cover is fixed with a motor on the upper surface. The output end of the motor is fixed with a guide rod. The outer surface of the guide rod is movably sleeved with a scraper. The inner side surface of the top cover is fixed with a fixed sleeve ring. The side surface of the fixed sleeve ring is movably provided with a stirring blade.

[0009] Preferably, the inner wall of the filter bin is fixed with a support rail. The side surface of the filter bin is provided with a through groove. The through groove penetrates through the side wall of the filter bin. The inner wall of the through groove is fixed with a clamping block. The outer side inner wall of the filter bin is fixed with a water outlet. The water outlet is communicated with the inside of the filter bin.

[0010] Preferably, the upper surface of the first filter plate is provided with a filter hole. The lower surface of the first filter plate is attached to the upper surface of the second filter plate. The side surface of the second filter plate is provided with a connecting groove. The support rail corresponds to the connecting groove and is movably clamped.

[0011] Preferably, the push rod is movably engaged with the inner wall of the through groove, the top cover is located at the upper end of the filter chamber, the motor output end is fixed with a rotating shaft, and a second bevel gear and a guide rod are fixed on the lower outer surface of the rotating shaft, with the second bevel gear located above the guide rod.

[0012] Preferably, the rotating shaft is movably engaged inside the fixed collar, and a first bevel gear is movably provided on the outer surface of the fixed collar. The stirring blade is fixed to the end surface of the first bevel gear, and the first bevel gear corresponds to and is engaged with the second bevel gear.

[0013] Preferably, the lower end of the rotating shaft is movably engaged inside the shaft center of the first filter plate, the scraper corresponds to and is engaged with the vortex block, and the length of the scraper is greater than the spacing between the vortex blocks.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When the shaft rotates, it drives the guide rod to rotate, which in turn drives the scraper to rotate. Since the scraper is simultaneously mounted on the outer surface of the vortex block and the guide rod, and the vortex block is vortex-shaped, the scraper gradually moves outward away from the axis as it rotates. The length of the scraper is slightly greater than the spacing of the vortex blocks, so as the scraper moves, it scrapes away the suspended matter remaining on the upper surface of the first filter plate, transferring the suspended matter to the outermost or center of the first filter plate. Since there are no filter holes at these two locations, the filter holes will not be blocked. By setting the motor to rotate in both directions, the residual suspended matter in the pulping wastewater can be scraped away while filtering, preventing the filter plate from clogging and enabling rapid filtration of pulping wastewater, thus improving the efficiency of wastewater recovery.

[0024] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1, please refer to Figures 1-6 This utility model provides a technical solution: a waste paper pulping wastewater recycling device, wherein a first filter plate 5 is fixed inside the filter chamber 1, a vortex block 9 is fixed on the upper surface of the first filter plate 5, and a second filter plate 11 is movably provided on the inner wall of the filter chamber 1 below the first filter plate 5. The first filter plate 5 is the main filter plate, and the second filter plate 11 is used to prevent wastewater from passing through the first filter plate 5 when pulping wastewater is injected into the filter chamber 1, so as to avoid the wastewater being filtered without stirring. A push rod 13 is fixed on the side surface of the second filter plate 11. Since the push rod 13 is fixed to the second filter plate 11, the rotation of the push rod 13 will drive the second filter plate 11 to rotate, so that the filter holes 10 opened on the second filter plate 11 correspond to the filter holes 10 opened on the first filter plate 5. At this time, the pulping wastewater can be filtered through the filter plate.

[0026] A motor 3 is fixed on the upper surface of the top cover 4. A guide rod 19 is fixed at the output end of the motor 3. A scraper 20 is movably sleeved on the outer surface of the guide rod 19. A fixing ring 14 is fixed on the inner surface of the top cover 4. An agitator 15 is movably sleeved on the side surface of the fixing ring 14. The rotating agitator 15 will agitate the pulping wastewater inside the filter chamber 1, so that the suspended solids in the wastewater are evenly dispersed, avoiding accumulation, and enabling the wastewater to be filtered more efficiently through the filter plate.

[0027] Based on Embodiment 1, in order to prevent the filter plates from clogging, a support rail 6 is fixed to the inner wall of the filter chamber 1, a through groove 8 is opened on the side surface of the filter chamber 1, the through groove 8 penetrates the side wall of the filter chamber 1, a clamping block 7 is fixed to the inner wall of the through groove 8, and a water outlet 2 is fixed to the inner wall of the outer side of the filter chamber 1, the water outlet 2 communicates with the inside of the filter chamber 1, a filter hole 10 is opened on the upper surface of the first filter plate 5, the lower surface of the first filter plate 5 is in contact with the upper surface of the second filter plate 11, a connecting groove 12 is opened on the side surface of the second filter plate 11, the support rail 6 corresponds to the connecting groove 12 and is movably locked, which plays a supporting and positioning role for the second filter plate 11, preventing the second filter plate 11 from shifting or falling off when rotating.

[0028] Push rod 13 is movably locked in the inner wall of through groove 8. Top cover 4 is located at the upper end of filter chamber 1. A rotating shaft 17 is fixed at the output end of motor 3. A second bevel gear 18 and guide rod 19 are fixed on the lower outer surface of rotating shaft 17. The second bevel gear 18 is located above guide rod 19. Rotating shaft 17 is movably locked in the inside of fixed collar 14. A first bevel gear 16 is movably provided on the outer surface of fixed collar 14. Stirring blade 15 is fixed on the end surface of first bevel gear 16. First bevel gear 16 corresponds to and is locked with second bevel gear 18. Rotating stirring blade 15 will stir the pulping wastewater inside filter chamber 1, so that the suspended solids in the wastewater are evenly dispersed, avoiding accumulation, and enabling the wastewater to be filtered more efficiently through the filter plate.

[0029] The lower end of the rotating shaft 17 is movably locked inside the shaft of the first filter plate 5. The scraper 20 corresponds to and is locked with the vortex block 9. The length of the scraper 20 is greater than the spacing of the vortex blocks 9. Since the scraper 20 is simultaneously movably locked on the outer surface of the vortex block 9 and the guide rod 19, and the vortex block 9 is vortex-shaped, the scraper 20 will gradually move outward away from the shaft while rotating. Since the length of the scraper 20 is slightly greater than the spacing of the vortex blocks 9, the scraper 20 will scrape off the suspended matter remaining on the upper surface of the first filter plate 5 while moving.

[0030] In actual use, pulping wastewater is injected into the filter chamber 1 through the water pipe set in the top cover 4. After it is full, the push rod 13 is pushed to rotate in the through groove 8, so that the push rod 13 is locked in the clamping block 7 and fixed. Since the push rod 13 is fixed to the second filter plate 11, the rotation of the push rod 13 will drive the second filter plate 11 to rotate, so that the filter holes 10 opened on the second filter plate 11 correspond to the filter holes 10 opened on the first filter plate 5. At this time, the pulping wastewater can be filtered through the filter plate.

[0031] While filtering pulping wastewater, the motor 3 is turned on. The motor 3 will drive the second bevel gear 18 to rotate through the rotating shaft 17. Since the first bevel gear 16 and the second bevel gear 18 are engaged, the rotation of the second bevel gear 18 will drive the stirring blade 15 to rotate through the first bevel gear 16. The rotating stirring blade 15 will stir the pulping wastewater inside the filter chamber 1, so that the suspended solids in the wastewater are evenly dispersed, avoiding accumulation, and enabling the wastewater to be filtered through the filter plate more efficiently.

[0032] When the rotating shaft 17 rotates, it drives the guide rod 19 to rotate, which in turn drives the scraper 20 to rotate. Since the scraper 20 is simultaneously mounted on the outer surface of the vortex block 9 and the guide rod 19, and the vortex block 9 is vortex-shaped, the scraper 20 gradually moves outward away from the axis while rotating. The length of the scraper 20 is slightly greater than the spacing of the vortex blocks 9, so the scraper 20 scrapes off the suspended matter remaining on the upper surface of the first filter plate 5 while moving, transferring the suspended matter to the outermost or center of the first filter plate 5. Since there are no filter holes 10 at these two locations, the filter holes 10 will not be blocked. By setting the forward and reverse rotation of the motor 3, the residual suspended matter can be scraped off while the pulping wastewater is being filtered, preventing it from clogging the filter plate and enabling rapid filtration of the pulping wastewater, thus improving the efficiency of wastewater recovery.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
