Description

Technical Field

[0001] The invention relates to the field of corrugated paper recycling, in particular to a waste corrugated paper recycling and pulping device. Background Art

[0002] Most modern items are packaged in cartons during transportation. These paper packages will become damaged and scrapped after long-term use. The damaged and scrapped cartons will be recycled to adapt to the development concept of green environmental protection.

[0003] CN218643060U discloses an environmentally friendly cardboard recycling pulping machine, which includes a mixing box, a mounting plate fixed to the top of the mixing box, a motor fixed to the top of the mounting plate, an output shaft of the motor fixedly connected to a transmission shaft located inside the mixing box, a mounting rod fixed to the side wall of the transmission shaft, a scraper provided at the end of the mounting rod, a chassis fixed to the bottom of the inner wall of the mixing box that cooperates with the scraper, and a gear ring fixed to the top of the inner wall of the mixing box that cooperates with the scraper. The environmentally friendly cardboard recycling pulping machine is provided with a scraper that can vibrate up and down and rotate with the chassis and gear ring. The scraper then scrapes off small cardboards stuck to the inner wall of the mixing box, effectively preventing small cardboards from sticking to the inner wall of the mixing box and effectively ensuring the pulping efficiency of the mixing box. Patents of the same type mostly focus on improvements to achieve sufficient stirring. However, during the stirring process, part of the paper has actually been broken into pulp, and this part is always stirred multiple times inside the stirring mechanism. This method will cause some pulp fibers to break, and at the same time increase the energy consumption of the excess stirring part. After the stirring is completed in the stirring chamber, in order to transfer the pulp out of the stirring chamber, there are two existing methods. One is to open the bottom of the stirring chamber to discharge the precipitated impurities and pulp together, and the other is to add a pump to use the pump to extract the pulp from the sizing pulp.

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0032] like Figure 1-8 As shown, the hydraulic crusher 1 includes a hydraulic crusher 1 for stirring shredded corrugated paper. The hydraulic crusher 1 includes a bearing part and a stirring part. A pressing plate 2 that moves up and down is provided inside the hydraulic crusher 1. A telescopic part 3 that lifts the pressing plate 2 to the top of the hydraulic crusher 1 is provided above the pressing plate 2. The telescopic part 3 is composed of a plurality of telescopic sleeves. A sieve hole 4 that passes through the upper and lower parts is provided on the surface of the pressing plate 2. The pulp formed after stirring and friction can be discharged through the sieve hole 4. The pulp larger than the sieve hole 4 continues to be crushed. A friction part 5 for increasing friction with the corrugated paper is provided on the bottom surface of the pressing plate 2. The friction part 5 is composed of a plurality of The hydraulic pulverizer 1 is composed of evenly distributed protrusions. By setting a friction part 5, the friction with the waste paper can be increased, so that the waste paper can be pulped faster. The bottom side wall of the hydraulic pulverizer 1 is provided with a water inlet 6, and the top side wall of the hydraulic pulverizer 1 is provided with a drain outlet 7. By setting a downwardly movable pressing plate 2 with a sieve hole 4 to contact and rub with the rotating pulp and the waste paper that has not become pulp, the pulp can be discharged through the sieve hole 4. The waste paper that has not formed pulp rubs with the friction part 5 to accelerate the decomposition of the waste paper, so that the pulping can be carried out faster and the pulp after pulping can be discharged more conveniently.

[0033] The inner wall of the hydraulic crusher 1 is provided with multiple groups of lead protrusions 8, the outer ring of the pressure plate 2 is provided with a lead groove 17 adapted to the lead protrusion 8, a limit ring 10 is fixedly installed above the pressure plate 2, and a rotating plate 11 is provided inside the limit ring 10 that rotates relative to the limit ring 10. The rotating plate 11 is fixedly connected to the free end of the telescopic part 3. The lead protrusion 8 has two functions: one is to increase the friction between the pulp and the side wall during the stirring process, so that the crushing can be achieved faster, and the other is to guide the pressure plate 2 to rotate and move downward.

[0034] The pressure plate 2 includes a fixed part 201, which includes an outer annular ring and an internal frame part that supports the annular ring. The guide groove 17 is opened on the outer ring of the fixed part 201, and the telescopic part 3 is fixedly connected to the fixed part 201. A replaceable screen 202 is provided below the fixed part 201. The screen 202 can be replaced with different pores or the screen 202 can be removed for cleaning, and is connected to the fixed part 201 by bolts. The friction part 5 is provided on the outer surface of the bottom end of the screen 202.

[0035] The drain outlet 7 is connected to the dewatering mechanism 9, and the water outlet end of the dewatering mechanism 9 is provided with a water tank 12. The water tank 12 can temporarily store the wastewater formed by dehydration. As the first water for pulping, there are no high requirements for the quality of water. It only needs to be soaked in water pulp to the extent that the paper is easy to break. However, because it is the first process, the degree of contamination of the water from the angle of impurities is relatively high.

[0036] The dewatering mechanism 9 includes a pipe 901 connected to the drain outlet 7, a filter tube 902 is provided in the horizontal section of the pipe 901, a scraper ring 903 is provided inside the filter tube 902 for scraping the filter tube 902, and a reciprocating mechanism 904 controls the movement of the scraper ring 903. The reciprocating mechanism 904 is composed of a motor and a lead shaft. The motor performs regular forward and reverse switching, which can drive the scraper ring 903 to move back and forth along the filter tube 902, thereby preventing the pulp from clogging the filter holes. A temporary storage box 905 is provided on the outer surface of the filter tube 902, and the temporary storage box 905 is connected to and passes through the water storage tank 12. Since the water inlet 6 always keeps water flowing, the water content in the pulp is relatively large. In the process of the pulp passing through the filter tube 902, part of the water is separated from the pulp under the action of water pressure, which can reduce the water content of the pulp and ensure that the pulp has a certain fluidity, so that it can be transported to the next process through the pipeline and the wastewater can be collected for the crushing process.

[0037] The water tank 12 includes a water inlet pump 13 for pumping water into the water tank. The interior of the water tank 12 is divided into a filter chamber 14 by a baffle plate at the upper end. A sieve plate is provided inside the filter chamber 14. The sieve plate can filter out most impurities. The filter plate needs to be cleaned regularly.

[0038] The sedimentation chamber 15 is used to precipitate impurities;

[0039] And the water chamber 16 is one-way connected to the sedimentation chamber 15. The simplest implementation method of this part is that the sedimentation chamber 15 and the water chamber 16 are closed by a partition, and the water in the sedimentation chamber 15 is actively pumped into the water chamber 16 by a pump. The water outlet of the water chamber 16 is provided with a drainage pump 18 connected to and passed through the water inlet 6. The top of the water chamber 16 is connected and passed through a water supply pipe 19, which is used for the water to be partially discharged and therefore needs to be replenished with new water. The water supply pipe 19 can be provided with a water level controller at the top to control opening or closing. When the water supply capacity of the sedimentation chamber 15 is less than the drainage capacity of the drainage pump 18, the water level in the water chamber 16 drops and the water supply pipe 19 can be opened to replenish water until the water level is restored.

[0040] The bottom side wall of the hydraulic pulverizer 1 is provided with a drain outlet 20 that can be opened and closed. A cover plate 21 is placed above the pressure plate 2 to cover the pressure plate 2 and prevent water from flowing upward. The cover plate 21 is spliced ​​together by multiple units. When the hydraulic pulverizer 1 needs to be cleaned, the pressure plate 2 is moved to the bottom and passed through the gap of the telescopic part 3, and the cover plate 21 is spliced ​​and covered on the top of the pressure plate 2. If necessary, the pressure plate 2 and the cover plate 21 can be magnetically attracted to prevent the cover plate 21 from being flushed up, and the pressure plate 2 is moved to the bottom. At this time, the water inlet 6 is opened, the drain outlet 20 is also opened, and the water is restricted to the bottom of the pressure plate 2, and the outlet is only the drain outlet 20. This can speed up the water flow rate through the drain outlet 20, so that the hydraulic pulverizer 1 can be cleaned with less water.

[0041] The side wall of the hydraulic pulverizer 1 is provided with a slag discharge port 22 above the drain port 7. During the hydraulic stirring process, ink foam will be generated. The slag discharge port 22 can be used to facilitate the discharge of the foam. The upper ring of the hydraulic pulverizer 1 is fixedly installed with a rotating mechanism 23 that rotates along the upper ring of the hydraulic pulverizer 1. The rotating mechanism 23 includes a gear ring provided above the hydraulic pulverizer 1 and a power part that drives the gear ring to rotate. A scraper 24 extending into the interior of the hydraulic pulverizer 1 is inserted above the rotating mechanism 23. The scraper 24 It includes at least two plug-in rods at an angle to each other, and a socket for accommodating the plug-in rod is provided on the upper surface of the gear ring. Through such an arrangement, the scraper 24 can be inserted and rotated after the pressure plate 2 enters the interior of the hydraulic pulverizer 1. The bottom end of the scraper 24 extends to the bottom of the slag discharge port 22. Through the liquid level control device, the liquid level of the hydraulic pulverizer 1 is located below the slag discharge port 22, and the scraper 24 is partially located below the liquid level and partially located above the liquid level. The rotation can accelerate the movement of the foam and discharge it from the slag discharge port 22.

[0042] The stirring part of the hydraulic pulverizer 1 is placed on top, and a through hole 25 is provided in the middle of the pressure plate 2 to accommodate the passage of the stirring power shaft of the hydraulic pulverizer 1. The hydraulic pulverizer 1 can also be placed at the bottom, so that the pressure plate 2 does not need to have a through hole 25. The bottom end of the pressure plate 2 is provided with a limit rod for limiting the maximum displacement of the pressure plate 2. The length of the limit rod is greater than the height of the stirring blades of the hydraulic pulverizer 1. This arrangement can prevent the pressure plate 2 from squeezing the blades of the hydraulic pulverizer 1. The water inlet 6 is distributed within the height range of the stirring blades of the hydraulic pulverizer 1, and the lead protrusion is set above this height, so it is more convenient to distribute the water inlet 6 at the bottom.

[0043] In another embodiment, the dewatering mechanism 9 includes a dewatering machine 906, which can be a centrifugal dewatering machine or one of other dewatering devices. The dewatering machine 906 can separate the water in the pulp from the pulp. The dewatering machine 906 is connected to and communicated with the dewatering machine 906 through the drain port 7. A collecting bucket 907 is provided at the water outlet of the dewatering machine 906. The collecting bucket 907 is connected to and communicated with the water storage tank 12, which can collect all the water and pack the pulp into blocks for transportation to the next process. Since the water contains more dust particles during the initial crushing process, the circulating water of this process is highly polluted. By recycling the contaminated water for crushing for the second time but not entering the later process, the cleaning treatment of the water in the later process can be reduced.

[0044] When in use, the collected corrugated paper is first sorted to remove large impurities, and then crushed into smaller pieces and put into the hydraulic crusher 1. Water is introduced into the water inlet 6 to submerge the corrugated paper and make the water level below the drain outlet 7. The stirring function is turned on for stirring. At this time, the pressing plate 2 moves downward under the action of the telescopic part 3 and is immersed in water. The water inlet 6 keeps entering water. During the stirring process, the corrugated paper can be accelerated by friction with the friction part 5 and the lead protrusion 8, and the telescopic part 3 continues to move downward to continuously squeeze the corrugated paper. The pulped part can move through the sieve hole 4 to the top of the pressing plate 2 and be discharged from the drain port 7 driven by the water flow. The corrugated paper below the pressing plate 2 continues to decrease, and the pressing plate 2 continues to move downward, reducing the activity space of the corrugated paper, increasing the contact probability with the friction part 5 and the lead protrusion 8, and accelerating the crushing. During the crushing process, the water level is kept below the slag discharge port 22. The scraper 24 is inserted above the rotating mechanism 23 and rotated along the hydraulic crusher 1. The bubbles, ink and impurities formed by the stirring above can be driven by the scraper 24 to be discharged from the slag discharge port 22;

[0045] When the pressing plate 2 moves to the bottom, the pressing plate 2 can be directly raised, and the material can be added to continue stirring, or the pressing plate 2 can be kept in place, the cover plate 21 can be spliced ​​to cover the top of the pressing plate 2, and the drain outlet 20 can be opened. The sewage under the pressing plate 2 is discharged, and at the same time, the water inlet 6 keeps the water inlet to flush the sediment at the bottom, and the sewage is discharged through the drain outlet 20, completing the cleaning of the hydraulic crusher 1. The drain outlet 20 is closed, and then the pressing plate 2 is raised, and the material can be added to continue stirring.
