Description

Technical Field

[0001] This invention relates to the field of papermaking and pulping technology, and more particularly to a straw papermaking and pulping equipment. Background Technology

[0002] Straw pulping is a crucial step in straw papermaking. The pulping process involves washing, crushing, and boiling the straw to extract the pulp. Cleaning removes dirt from the straw, while crushing and boiling facilitate better pulp extraction. The process encompasses several key stages: First, in the pretreatment stage, the straw undergoes screening, crushing, and drying. Next, in the pulping stage, the pretreated straw is mixed with water and processed into pulp using mechanical or chemical methods. Finally, in the papermaking stage, the pulp is spread on a paper machine and undergoes multiple pressing and drying processes to produce finished paper.

[0003] According to the search, CN221320480U proposes "a straw papermaking and pulping device", which uses a working chamber to wash, crush and boil straw to produce pulp. The movement of one of the movable sleeves drives the connecting rod to move, thereby driving the other two movable sleeves to move. The movement of the movable sleeves drives the blades to rotate, thereby completing the use and storage of the blades.

[0004] However, this patent has the following drawbacks: crushing, washing, and boiling are all completed in one space, which leads to a high risk of cross-contamination of the processes. Washing wastewater mixes with crushed straw residue and boiling pulp. Furthermore, the integration of multiple processes in a single space means that if any part, such as the blade or heater, malfunctions, the entire pulping process will be interrupted. Repairs require emptying the material in the chamber, which significantly reduces production efficiency. In addition, the residue on the filter plate needs to be manually cleaned by opening the sealed door, and the filter holes on the filter plate also need to be manually cleaned after they become clogged. It is impossible to achieve automated cleaning and unblocking.

[0005] A search revealed CN110924219A, which proposes "a straw pulping device." The device comprises a crushing tank fixedly installed on the top of a pulping chamber, with a crushing rod fixedly installed inside the crushing tank. Crushing blades are wound around the crushing rod and fixedly connected to it. The crushing rod is rotatably connected to the output shaft of a first motor mounted on the left side of the top of the pulping chamber, allowing the first motor to drive the crushing rod to rotate. A feed hopper connected to the right side of the top of the crushing tank allows straw and other materials to enter the crushing tank. The rotation of the crushing blades on the crushing rod crushes the straw and other materials inside the tank. The crushed straw material is then carried into the pulping chamber through a discharge pipe connected to the bottom of the crushing tank.

[0006] However, this patent has the following defects: the inner wall of the crushing tank lacks a cleaning structure, and impurities such as residual straw fragments fall down and adhere to the surface of the crushing rod and crushing blades, which prevents the crushing blades from fully contacting the newly entered straw material. This not only reduces the crushing efficiency, but also increases the size difference of the output straw fragments, which in turn affects the washing and pulping effect, resulting in a decrease in pulping rate and uneven distribution of pulp fibers. Summary of the Invention

[0007] The purpose of this invention is to solve the problems in the prior art where the residue on the filter plate needs to be manually cleaned by opening the sealed door, and the filter plate pores also need to be manually cleaned after they become clogged, making it impossible to achieve automated cleaning and unblocking.

The dredging assembly is located above the filter plate. The filter plate has filter holes. The dredging assembly is used to dredge the waste residue in the filter holes. A first baffle is slidably connected to the bottom of the filter plate along its length. The number of rows of the first baffle is the same as the number of filter holes. A support block is fixed to the bottom of the first baffle. Threaded rods are rotatably connected between the support blocks. A waste discharge port is connected to the bottom of the wastewater tank. A motor is installed at the waste discharge port through the support rod. The output end of the motor is fixedly connected to one end of the threaded rod.

[0009] As a further embodiment of the present invention, the wastewater treatment structure further includes a drain pipe connecting the cleaning chamber and the wastewater tank. A pad is slidably connected to the top of the wastewater tank. The pad is provided with a first drain outlet and a second drain outlet. Slots are provided inside the pad at the positions of the first and second drain outlets. An electric push rod is installed inside the pad through an opening cavity. The first and second drain outlets are sealed inside the pad by a slidably connected sealing plate. The output end of the electric push rod is fixedly connected to the sealing plate. A return spring is fixedly connected to the top of the filter hole and the inside of the wastewater tank. The top of the return spring is fixedly connected to the bottom of the pad.

[0010] As a further embodiment of the present invention, the unblocking component includes an inclined groove provided on the inner wall of the wastewater tank, a hollow plate slidably connected to the inside of the wastewater tank along the inclined groove, a first spring provided inside the inclined groove, a scraper provided at the bottom of the hollow plate, a hollow cylinder installed in the hollow part of the hollow plate, a second spring provided inside the hollow cylinder and slidably connected to a silicone top block, and the bottom of the second spring being fixedly connected to the top of the silicone top block.

[0011] As a further embodiment of the present invention, the unblocking assembly also includes a top plate fixed to the bottom of the filter plate, a rotatable second baffle is provided at the middle position of the sealing plate via a rotating shaft, the rotating shaft is provided with a torsion spring to facilitate the second baffle to reset after opening, a discharge inclined plate is fixed at the bottom of the pad inside the wastewater tank, and the discharge inclined plate is provided with a groove to facilitate water passage, the end of the discharge inclined plate is located at the waste discharge port.

[0012] As a further embodiment of the present invention, the scraping structure includes a groove provided on the inner wall of the crushing tank, an annular scraper is slidably connected along the groove inside the crushing tank, and one end of the No. 1 steel cable is connected to the scraper and the other end is fixedly connected to the pad.

[0013] As a further embodiment of the present invention, a No. 3 spring is provided inside the slide groove, and one end of the No. 3 spring is fixedly connected to the scraper.

[0014] As a further embodiment of the present invention, the partition is provided with an opening and closing structure, which is used for the cleaned straw in the washing chamber to enter the cooking chamber.

[0015] As a further embodiment of the present invention, the opening and closing structure includes a third baffle that is slidably connected inside the partition, a fourth spring that is fixed inside the partition, a second steel cable that is connected to one end of the third baffle, and a hollow plate that is connected to one end of the second steel cable.

[0016] As a further embodiment of the present invention, a water pump is installed on the back of the wastewater tank, the water pump is connected to a pipeline, the end of the pipeline is located inside the first water tank, and the top of the pipeline is located inside the cleaning tank.

[0017] The straw papermaking and pulping equipment proposed in this invention has the following advantages: 1. This equipment features separate crushing, washing, and boiling processes, effectively preventing cross-contamination. Wastewater from the washing chamber does not mix with crushed straw residue or boiling slurry, ensuring the purity of each process and improving the quality of the final product. Furthermore, if equipment in one stage, such as the crushing blades or cooking components, malfunctions, it will not affect the normal operation of other processes. There is no need to empty the entire working chamber, greatly improving production efficiency. Maintenance ports are provided in the corresponding chambers for subsequent repairs. In addition, this equipment comprehensively recycles wastewater. In the filtration stage, a clever structural design automatically cleans and unclogs the filter plates without requiring manual operation by opening the sealed door, reducing manual intervention and labor intensity. It also avoids the hassle of manual cleaning, further enhancing the continuity and stability of production. 2. This equipment is equipped with a scraper structure inside the crushing tank. When the pad plate descends due to the accumulation of wastewater at the No. 1 drain outlet, the No. 1 steel cable drives the scraper to slide along the groove on the inner wall of the crushing tank. During the movement, the scraper can efficiently scrape off the straw fragments adhering to the inner wall of the crushing tank, ensuring that there are no residues on the inner wall of the crushing tank. This prevents residual fragments from adhering to the surface of the crushing rod and crushing blades, reducing the obstruction to the crushing process. As a result, the output straw fragments are more uniform in size, providing a better raw material foundation for subsequent washing and pulping processes. Attached Figure Description

The following describes embodiments of the invention based on its overall structure.

[0022] A straw pulping and papermaking device includes: a working box 1, the interior of which is divided into a washing chamber 3 and a cooking chamber 4 by a partition 2; a pulverizing tank 9 installed on the top of the working box 1; pulverizing blades 10 installed inside the pulverizing tank 9 by a pulverizing rod; a feed inlet 11 installed on the top of the pulverizing tank 9; a discharge outlet 47 installed at the bottom of the pulverizing tank 9; a liquid storage tank 5 at the bottom of the working box 1, the interior of which is divided into a first water tank 6 and a second water tank 7; a wastewater tank 8 installed on the top of the liquid storage tank 5; a wastewater treatment structure installed inside the wastewater tank 8; a wall scraping structure installed inside the pulverizing tank 9 for cleaning straw fragments from the inner wall of the pulverizing tank 9; the wastewater treatment structure being linked to the wall scraping structure by a first steel cable 12; the wastewater treatment structure including an inclined filter plate 13 and a dredging component, the dredging component being located above the filter plate 13; and the filter plate 13 being equipped with a filter... Hole 14, the unblocking assembly is used to unblock waste residue in the filter hole 14, the bottom of the filter plate 13 is slidably connected to a first baffle 15 along the length direction, the number of rows of the first baffle 15 is the same as the number of filter holes 14, the bottom of the first baffle 15 is fixed with a support block 16, the support blocks 16 are rotatably connected with threaded rods 17, the bottom of the wastewater tank 8 is connected to a waste discharge port 18, the waste discharge port 18 is mounted with a motor 19 through the support rod, the motor 19... The output end is fixedly connected to one end of the threaded rod 17. A water pump 45 is installed on the back of the wastewater tank 8. The water pump 45 is connected to a pipe 46. The end of the pipe 46 is located inside the first water tank 6, and the top of the pipe 46 is located inside the washing chamber 3. After the straw enters the crushing tank 9 through the feed inlet 11, it is crushed by the crushing blades 10 and then enters the washing chamber 3 through the discharge port 47. The water pump 45 is started to inject the water in the first water tank 6 into the washing chamber 3 through the pipe 46 to complete the washing.

[0023] Furthermore, the wastewater treatment structure also includes a drain pipe 20 connecting the cleaning chamber 3 and the wastewater tank 8. A pad 21 is slidably connected to the top of the wastewater tank 8. The pad 21 is provided with a first drain outlet 22 and a second drain outlet 23. Slots 24 are provided inside the pad 21 at the positions of the first drain outlet 22 and the second drain outlet 23. An electric push rod 25 is installed inside the pad 21 through an opening cavity. The first drain outlet 22 and the second drain outlet 23 are sealed inside the pad 21 by a slidably connected sealing plate 26. The output end of the electric push rod 25 is fixedly connected to the sealing plate 26. A return spring 40 is fixedly connected to the top of the filter hole 14 and the inside of the wastewater tank 8. The top of the return spring 40 is fixedly connected to the bottom of the pad 21. During filtration, wastewater enters the filtration process through the No. 1 drain outlet 22. When cleaning and unblocking are required, the electric push rod 25 extends and drives the sealing plate 26 to insert into the slot 24, completely sealing the No. 1 drain outlet 22. This causes the wastewater to accumulate on the top of the pad plate 21. As the weight of the accumulated wastewater increases, the pad plate 21 descends, providing power for the subsequent linkage scraping structure and unblocking components.

[0024] Next, the unblocking assembly includes a sloping groove 27 on the inner wall of the wastewater tank 8. A hollow plate 28 is slidably connected to the inside of the wastewater tank 8 along the sloping groove 27. A first spring 33 is installed inside the sloping groove 27. A scraper 29 is installed at the bottom of the hollow plate 28. A hollow cylinder 30 is installed in the hollow part of the hollow plate 28. A second spring 34 is installed inside the hollow cylinder 30 and is slidably connected to a silicone top block 32. The bottom of the second spring 34 is fixedly connected to the top of the silicone top block 32. The unblocking assembly also includes a top plate 35 fixed to the bottom of the filter plate 13. A rotatable second baffle 37 is installed at the middle position of the sealing plate 26 via a rotating shaft 36. The rotating shaft 36 is equipped with a torsion spring to facilitate the second baffle 37 to reset after opening. The inside of the wastewater tank 8 is located at the bottom of the pad 21. The part is fixed with a feeding inclined plate 48, and the feeding inclined plate 48 is provided with a slot to facilitate water passage. The end of the feeding inclined plate 48 is located at the waste discharge port 18. When the pad plate 21 closes the first drain port 22 and collects wastewater, it falls down and contacts the top of the hollow plate 28. The electric push rod 25 is controlled to retract and open the first drain port 22. The wastewater at the top of the pad plate 21 is discharged through the first drain port 22 to the space between the hollow plate 28 and the filter plate 13. Because the filter hole 14 was blocked by the first baffle 15, the wastewater could not fall. As a result, the wastewater pushed the hollow plate 28 to slide along the inclined groove 27 and compress the first spring 33. When the hollow plate 28 moves, the bottom scraper 29 contacts the top of the filter plate 13 to scrape off surface impurities. At the same time, the silicone top block 32 in the hollow cylinder 30, under the action of the second spring 34, moves with the hollow plate 28 and inserts into the filter hole 14 to clear the internal blockage.

[0025] In addition, the scraping structure includes a groove 38 on the inner wall of the crushing tank 9. An annular scraper 39 is slidably connected to the inside of the crushing tank 9 along the groove 38. One end of the first steel cable 12 is connected to the scraper 39 and the other end is fixedly connected to the pad 21. A third spring 41 is installed inside the groove 38, and one end of the third spring 41 is fixedly connected to the scraper 39. When the pad 21 descends due to the accumulation of wastewater at the first drain outlet 22, the scraper 39 is driven by the first steel cable 12 to slide along the groove 38 on the inner wall of the crushing tank 9. During the movement of the scraper 39, the straw fragments adhering to the inner wall of the crushing tank 9 are scraped off, ensuring that there are no residues on the inner wall of the crushing tank 9 and ensuring the efficiency of subsequent straw crushing.

[0026] As an example, the partition 2 is equipped with an opening and closing structure inside. The opening and closing structure is used for the cleaned straw in the washing chamber 3 to enter the cooking chamber 4. The opening and closing structure includes a third baffle 42 that is slidably connected inside the partition 2. A fourth spring 43 is fixed inside the partition 2. One end of the third baffle 42 is connected to a second steel cable 44. One end of the second steel cable 44 is connected to a hollow plate 28. When wastewater is discharged through the first drain outlet 22 and pushes the hollow plate 28 to move along the inclined groove 27, the hollow plate 28 pulls the second steel cable 44, causing the third baffle 42 to retract into the partition 2 and compress the fourth spring 43. Then the partition 2 opens. Since the wastewater in the washing chamber 3 has been discharged through the drain pipe 20 and the first drain outlet 22, only the cleaned straw remains. The straw falls into the cooking chamber 4 along the inclined side of the partition 2 and the open opening.

[0027] Working principle: Straw enters the crushing tank 9 through the feed inlet 11. The crushing blades 10 rotate to crush the straw in the tank. The straw then enters the washing chamber 3 through the discharge port 47. The water pump 45 is then started to inject water from the No. 1 water tank 6 into the washing chamber 3 through the pipe 46. After washing, the drain pipe 20 is opened. The baffle on the drain pipe 20 can block the straw and prevent it from entering the drain pipe 20. The wastewater discharged through the drain pipe 20 reaches the top of the pad plate 21. During the filtration of the cleaning wastewater, which is the normal state, the output end of the electric push rod 25 is in the retracted state and moves from the slot 24 with the long sealing plate 26. This causes the second drain outlet 23 to be open in the normal state. Therefore, the wastewater on the top of the pad plate 21 will fall to the top of the filter plate 13 through the second drain outlet 23. Then, the impurities in the wastewater are intercepted and filtered through the filter holes 14. The water then falls through the filter plate 13 and passes through the feed inclined plate 48 to the interior of the first water tank 6, where the filtered wastewater is stored. When the straw is cleaned again, the water pump 45 is started to inject the filtered water back into the cleaning tank 3 through the pipeline 46, thereby realizing the comprehensive recycling of wastewater. However, with prolonged filtration, a layer of impurities will adhere to the surface of the filter plate 13, and there is also a risk of clogging the filter holes 14. The removal of impurities from the surface of the filter plate 13 and the unclogging of the filter holes 14 can be done during the drainage of the straw washing process, as follows: In normal filtration conditions, the first baffle 15 and the filter hole 14 are offset. When the above purpose needs to be achieved, the motor 19 drives the threaded rod 17 to rotate, and then moves the first baffle 15 through the support block 16, thus completely blocking the filter hole 14. Figure 9 As shown, the electric push rod 25 then extends and moves with the long sealing plate 26 to insert into the slot 24, thereby sealing the second drain port 23. At this time, the pad 21 is in a completely closed state. Wastewater in the cleaning chamber 3 is normally discharged into the wastewater tank 8 through the drain pipe 20. However, since the pad 21 is closed, the wastewater will accumulate on the top of the pad 21 but will not fall down. As the wastewater on the pad 21 increases, the weight increases accordingly. Then the pad 21 slides down and compresses the return spring 40. The pad 21 descends and moves the scraper 39 in the crushing tank 9 through the first steel cable 12. The scraper 39 moves along the slide 38 and compresses the third spring 41. The movement of the scraper 39 scrapes off the straw impurities adhering to the inner wall of the crushing tank 9, which helps to solve the shortcomings mentioned in the background art. When the bottom of the pad 21 descends to contact the top of the hollow plate 28, it can no longer descend. At this time, the first drain port 22 is opened by the electric push rod 25. The width of the opening of the first drain port 22 is proportional to the length of the retraction of the output end of the electric push rod 25. After opening, the wastewater accumulated on the top of the pad 21 is discharged between the hollow plate 28 and the filter plate 13. Since the filter holes 14 are all blocked by the first baffle 15 at this time, the water will not fall from the filter plate 13. As the wastewater increases at the top of the filter plate 13 and the top of the hollow plate 28, the wastewater will push the hollow plate 28 to move along the inclined groove 27 and compress the first spring 33. When the hollow plate 28 moves, the scraper 29 at its bottom contacts the top of the filter plate 13, and then the scraper 29 scrapes the impurities on the top of the filter plate 13. By controlling the size of the opening of the first drain outlet 22, the wastewater flows at a uniform speed to the top of the filter plate 13. By controlling the water volume, the hollow plate 28 can move slowly along the inclined groove 27. Simultaneously, when the hollow plate 28 moves obliquely downward under the action of water, the second spring 34 is compressed when the silicone top block 32 contacts the solid part of the filter plate 13. As the hollow plate 28 moves to the position of the filter hole 14, the second spring 34 returns to its original position, and the silicone top block 32 is inserted into the interior of the filter hole 14. This pushes the blocky blockage in the filter hole 14 into the interior of the first baffle 15. Since the silicone top block 32 is elastic, as the hollow plate 28 moves, the previously inserted silicone top block 32 will bend and be pulled out, and then be inserted into the next set of filter holes 14 as the hollow plate 28 moves. This operation is repeated, which can not only scrape off the impurities on the surface of the filter plate 13, but also unclog the filter holes 14. The whole process is achieved by the force applied to the hollow plate 28 by the wastewater, and no manual cleaning is required. It can achieve automated cleaning and unclogging, thereby solving the shortcomings of the prior art. Then, the rotation of motor 19 causes the first baffle 15 to move slightly. The slight movement of the first baffle 15 opens a gap in the filter hole 14. However, it is important to ensure that the first baffle 15 is not disengaged from the top plate 35. This is to prevent impurities pushed down from the first baffle 15 from re-entering the wastewater. When the wastewater is discharged from the filter plate 13, the waste outlet 18 is closed. After the wastewater is discharged, the motor 19 moves the first baffle 15 again and hits the top plate 35. The blocking effect of the top plate 35 causes the rotating shaft 36 and the second baffle 37 to rotate, so as to open the first baffle 15. Then the impurities in the first baffle 15 are discharged from the opening position of the second baffle 37 along with the water in the first baffle 15. A small amount of water discharged will enter the first water tank 6 through the feeding inclined plate 48, while the discharged impurities will fall into the opened waste discharge port 18 along the slope of the feeding inclined plate 48, and then be discharged through the waste discharge port 18, thus realizing the cleaning and unblocking process of the entire filter plate 13. Since the washed straw needs to enter the cooking chamber 4, the partition 2 needs to be opened. This is achieved using the discharged wastewater. The wastewater is discharged to the top of the pad 21, opening the first drain outlet 22. Using the above operation, the hollow plate 28 tilts downwards, pulling the second steel cable 44. At this point, all the wastewater at the top of the partition 2 has been discharged, leaving only the washed straw. The second steel cable 44 is pulled, causing the third baffle 42 to retract into the partition 2 and compressing the fourth spring 43. The retraction of the third baffle 42 opens the partition 2, with the side of the partition 2 furthest from the third baffle 42 designed to be inclined. The straw at the top of the partition 2 then falls into the cooking chamber 4 along the slope and through the opening. The entire operation of this equipment greatly reduces manual intervention, relying entirely on wastewater to complete a series of operations. This equipment demonstrates significant innovation in wastewater utilization, and its separate design for crushing, washing, and cooking solves the shortcomings of the prior art.

[0028] An alternative solution is proposed below. In actual use, the above operations, such as unblocking and cleaning the filter plate 13 and opening the partition 2, are all accomplished by draining water from the first drain port 22. Therefore, the role of the second drain port 23 is minimal in actual use. The purpose of the second drain port 23 is only to increase the drainage speed during simple filtration, which means that unblocking and cleaning are not required. Since the opening of the second drain port 23 is larger, the second drain port 23 can be removed, leaving only the first drain port 22.

[0029] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
