Description

Technical Field

[0001] This invention relates to the field of cocoon boiling, and more specifically to a highly efficient and environmentally friendly cocoon boiling device. Background Technology

[0002] Silkworm cocoons are the raw material for silk production. The process of separating silkworm cocoons into raw silk is called silk production. The silk production process often includes steps such as drying cocoons, peeling cocoons, selecting cocoons, boiling cocoons, reeling, rewinding, and finishing. Dry cocoons cannot be directly separated into silk fibers sequentially. Due to the unique way silkworms spin their cocoons, the silk fibers are arranged in "S" and "8" shapes, creating many overlapping points. Furthermore, the sericin content varies from the outside to the inside of the cocoon layer, resulting in some silk fibers being heavily adhered and difficult to separate. After drying and storage, the sericin adhesion between the cocoon layers becomes even stronger, at which point the adhesive force between the silk fibers greatly exceeds their cutting strength. Therefore, if the silk fibers are extracted directly without boiling the cocoons, they will be cut and cannot be reeled.

[0003] Boiling cocoons involves using water and heat to swell and appropriately dissolve the sericin, allowing the cocoons to be smoothly and sequentially separated from the cocoon layer during silk reeling. From a technological perspective, boiling cocoons can be divided into three processes: penetration, cooking, and adjustment and protection. Each process, as a means of boiling, primarily plays the roles of penetration and cooking, aiming to ensure even cooking between the cocoon layer and the individual cocoons. Boiling not only reduces the sericin's strength but also increases the cocoon's wet strength, making the sericin's strength much lower than the cocoon's cutting strength. This ensures the smooth and sequential separation of the cocoon from the cocoon layer while reducing the risk of breakage caused by excessive cocoon movement during reeling. The equipment used for boiling cocoons is a cocoon boiling machine, which directly introduces a pile of cocoons into water for steaming. This easily leads to uneven heating, resulting in uneven cooking (different cooking rates between cocoons). At the same time, the different water absorption and penetration capacities of the cocoons cause surface cooking (the outer layer of the cocoon is cooked while the inner layer is still raw) and spot cooking (different parts of the cocoon are not cooked evenly). Existing cocoon boiling machines cause the cocoons to float on the surface of the water during steaming, resulting in low steaming efficiency. The wastewater generated after steaming is discharged directly without treatment, which easily pollutes the environment. Therefore, there is a need to propose a more efficient and environmentally friendly cocoon boiling device. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the background art and provide a highly efficient and environmentally friendly cocoon boiling device.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A highly efficient and environmentally friendly cocoon boiling device includes a frame. From left to right, the frame is equipped with a vacuum tank, a cocoon separating and spreading mechanism, and a cocoon boiling mechanism. A filter frame is located at the bottom of the vacuum tank, and a water storage tank is located at the bottom of the filter frame. The water storage tank and the wastewater from the cocoon boiling mechanism are connected to a wastewater treatment mechanism via pipes. The side of the filter frame near the cocoon separating and spreading mechanism has no filter holes, allowing water to flow into the mechanism. A discharge mechanism is located at the outlet of the filter frame, including an electric discharge push rod. A discharge plate is hinged to the push rod end of the electric discharge push rod, and the motor end of the electric discharge push rod is hinged to the filter frame, allowing the discharge plate to open and close automatically via the electric push rod. The bottom of the filter frame is inclined, allowing the cocoons to smoothly enter the vibrating discharge plate.

[0006] This invention uses a vacuum tank to permeate silkworm cocoons. Afterward, the vacuum tank is opened, and the cocoons and water are poured into a filter frame at the bottom. The filter frame retains the cocoons while the water flows into a water storage tank at the bottom. The outlet of the filter frame is then opened, and a cocoon-separating and spreading mechanism separates and spreads the cocoons evenly within a cocoon-separating screen frame. The cocoons then enter a cocoon soaking and cooking mechanism, where they are submerged in water for thorough cooking. This not only improves cooking efficiency but also prevents the cocoons from being partially cooked, surface-cooked, or spotted during the cooking process. Wastewater in the water storage tank and wastewater generated after cooking are treated by a wastewater treatment system to meet discharge requirements, making it more environmentally friendly.

[0007] Preferably, the cocoon separating and spreading mechanism includes a vibrating discharge plate, a first conveyor belt, a second conveyor belt, and a cocoon separating screen frame. A discharge port is provided on the right side of the screen frame. The vibrating discharge plate is inclinedly positioned at the discharge port. The starting end of the first conveyor belt is located below the end of the vibrating discharge plate, and the starting end of the second conveyor belt is located below the end of the first conveyor belt. Several cocoon separating screen frames are arranged in a close array on the second conveyor belt. The vibrating discharge plate is triangular in shape with its width gradually decreasing from the starting end to the end, allowing the cocoons to enter the first conveyor belt sequentially, which is beneficial for subsequent spreading. Baffles are provided on both sides of the vibrating discharge plate to prevent material from falling from the sides. The vibrating discharge plate is controlled by an existing vibrating motor, which is a mature technology and will not be elaborated upon here. For better material vibration, a vibrating motor can also be installed on the screen frame.

[0008] This invention disperses the material by vibrating the discharge plate, then evens it out by the first conveyor belt, and finally spreads it out on the silkworm cocoon separating screen frame by the second conveyor belt, thus completing the function of spreading and separating the silkworm cocoons.

[0009] Preferably, the silkworm cocoon soaking and boiling mechanism includes a box with a top opening, a transition plate, a pressing electric push rod, a pressing plate, and a spring structure. The transition plate is located at the opening of the box, the spring structure is located between the transition plate and the box, the pressing plate is located above the transition plate, the pressing electric push rod is located above the transition plate, the push rod end of the pressing electric push rod is fixedly connected to the pressing plate, and the motor end of the pressing electric push rod is fixedly connected to the frame. The transition plate has three or more pulleys arranged in an array, and the rolling direction of the pulleys is the same as the conveying direction of the second conveyor belt. The right side and the front and rear sides of the box are provided with baffles, and the baffle on the right side is provided with a limit switch.

[0010] This invention uses pulleys on a transition plate to slide the cocoon separating screen frames, which are conveyed to the end of the second conveyor belt, onto the top of the transition plate. Subsequent cocoon separating screen frames are then sequentially conveyed to the transition plate, causing the foremost frame to move forward. This moves all the cocoon separating screen frames on the conveyor belt to the top of the housing. Then, pressing the electric push rod downwards moves the pressing plate downwards, pressing all the cocoon separating screen frames and the transition plate below the water surface. The boiling process then begins. After completion, pressing the electric push rod returns the pressing plate to its original position. Because the transition plate has a spring structure underneath, it releases pressure and pulls the cocoon separating screen frames out of the water, thus separating the cocoons from the water. The boiled cocoons are then collected, completing the process of laying the cocoons flat and submerging them in the boiling water.

[0011] Preferably, two spring structures are stacked together. Each spring structure includes a compression spring, an upper fixing plate, a lower fixing plate, and a silicone protective sleeve. The upper fixing plate is located at the top of the compression spring, and the lower fixing plate is located at the bottom of the compression spring. Both the upper and lower fixing plates have locking blocks on the side away from the compression spring. The housing and the transition plate each have locking grooves that cooperate with the locking blocks. The silicone protective sleeve is fitted and fixed on the outside of the compression spring. A closed space is formed between the silicone protective sleeve, the upper fixing plate, and the lower fixing plate, and the compression spring is located within the closed space.

[0012] This invention uses a locking block and a locking slot to fix the spring structure. To enhance the stability, adhesive can be applied between the locking block and the locking slot.

[0013] This invention ensures that the compression spring can work normally by using a silicone protective sleeve, while preventing impurities from entering the compression spring. If there are impurities on the compression spring, their presence may interfere with the spring's elasticity and movement, affecting the reciprocating motion of the transition plate. Impurities will cause the spring to experience greater resistance during compression and extension, reducing the spring's response speed and sensitivity, thereby affecting the reciprocating motion of the transition plate.

[0014] Preferably, the top of the silicone protective sleeve is formed with an upper through groove that can fit into the locking block, the bottom of the silicone protective sleeve is formed with a lower through groove that can fit the lower fixing plate, the top of the silicone protective sleeve and the bottom of the inner sidewall are both formed with silicone retaining rings, and the upper fixing plate and the lower fixing plate are both formed with annular limiting grooves that cooperate with the silicone retaining rings, thereby enhancing the sealing performance through the silicone retaining rings and the annular limiting grooves.

[0015] Preferably, the chamber is equipped with a temperature mixing mechanism, which includes a rotating shaft, a first bearing, a second bearing, a stirring paddle, a fixed rod, a spur gear, a rack, a driven bevel gear, and a driving bevel gear. The bottom of the rotating shaft is rotatably connected to the chamber via the first bearing. The driven bevel gear is fixed to the top of the rotating shaft. The driving bevel gear meshes with the driving bevel gear. The middle part of the driving bevel gear is fixedly connected to the fixed rod. The spur gear is sleeved and fixed on the fixed rod. The rack meshes with the spur gear. The top of the rack is fixedly connected to the bottom of the transition plate. The stirring paddle is located at the lower part of the rotating shaft. The fixed rod is fixedly connected to the inner ring of the second bearing. The outer ring of the second bearing is fixed to the chamber. The connection between the second bearing and the chamber can be achieved through a bracket. This fixing method is very mature and therefore has not been elaborated upon in this application. The liquid inside the chamber can be heated by a heating wire.

[0016] This invention involves pressing down the electric push rod, which moves the rack downwards, causing the spur gear to rotate. The rotation of the spur gear drives the active bevel gear to rotate, which in turn drives the passive bevel gear to rotate, thus causing the rotating shaft to rotate. This causes the stirring paddle to start stirring, ensuring that the temperature inside the chamber remains consistent from top to bottom and left to right. This ensures that the silkworm cocoons inside the chamber are heated evenly, reducing the phenomenon of the cocoons being partially cooked and shortening the cooking time.

[0017] The invention allows the electric push rod to move up and down, which in turn causes the rack to move up and down, enabling the stirring paddle to rotate in both directions and continuously stir, thus maintaining a consistent temperature throughout the chamber.

[0018] Preferably, the stirring paddle includes a connecting rod, stirring blades, and a conical stirring tube. Three or more connecting rods are arrayed on the side wall of the rotating shaft, and several stirring blades are arrayed on the side wall of each connecting rod. The conical stirring tube is fixed obliquely to the side wall of the rotating shaft, and the large-diameter end of the conical stirring tube is inclined downward at 10°-15°.

[0019] The conical stirring tube of the present invention generates turbulence at the cone end through acceleration, displacement and stagnation, and stirs the medium, thereby causing the fluid to flow and generating a new dynamic mixing motion. Since alkaline substances need to be added to the box, the conical stirring tube can not only make the alkaline substances and liquids uniformly mixed in the early stage, but also keep the temperature in the box uniform in the later stage.

[0020] Preferably, the wastewater treatment unit includes a bar screen, an equalization tank, an SBR tank, a sludge thickening tank, and a sludge dewatering machine connected in sequence for continuous use.

[0021] Wastewater from cocoon boiling, silk reeling, and domestic wastewater enters a screen well. After being screened to remove large particles and floating debris, the wastewater enters a regulating tank. In the regulating tank, it is mixed and homogenized with UASB effluent before entering the SBR tank. During the influent stage, the wastewater enters the reaction tank and is thoroughly mixed with activated sludge by a stirrer. The microorganisms in the activated sludge begin to adsorb organic matter in the wastewater. Through aeration, the activated sludge begins to degrade the organic matter in the wastewater, and nitrification begins, converting ammonia nitrogen in the wastewater into nitrate nitrogen and nitrite nitrogen. The COD, BOD, and ammonia nitrogen levels in the wastewater decrease. After aeration stops, sedimentation begins. As dissolved oxygen is continuously consumed, the system gradually transitions from an aerobic stage to an anoxic stage, and finally to an anaerobic stage, where denitrification begins. Finally, the SBR supernatant is discharged after passing through a decanter to meet the discharge concentration requirements in Table 1 of the "Water Pollutant Discharge Standard for Silk Reeling Industry" (GB28936-2012).

[0022] The wastewater from the tailings process first enters the primary sedimentation and equalization tank, where most of the sericin, fibroin, crude protein, and broken pupae are precipitated and removed. The pH is adjusted to between 7 and 9. The effluent from the primary sedimentation and equalization tank is pumped into a pressurized dissolved air tank and then, along with the returned clarified liquid, pressurized and pumped into the dissolved air flotation (DAF) tank. PAC and PAM are added as coagulants to further remove suspended solids and oils. The effluent from the DAF tank flows into the hydrolysis and acidification tank, where facultative anaerobic microorganisms hydrolyze and acidify the large molecules and recalcitrant organic matter in the wastewater, transforming them into smaller molecules and more readily biodegradable soluble organic matter. This improves the biodegradability of the wastewater, removes some COD and BOD, and homogenizes the water quality to a certain extent. The effluent from the hydrolysis and acidification tank is pumped to the UASB anaerobic reactor, where anaerobic granular sludge degrades and transforms most of the organic matter in the wastewater into CH4, CO2, H2O, or converts it into cellular substances, effectively reducing the COD and BOD levels of the wastewater. The UASB effluent flows by gravity into the equalization tank.

[0023] The sludge in the primary sedimentation equalization tank mainly consists of sericin, fibroin, crude protein, and broken pupae, which can be separated and extracted after treatment. The scum from the dissolved air flotation tank and the excess sludge from the UASB and SBR processes are gravity-concentrated in the sludge thickening tank, then pumped to a sludge dewatering machine for dewatering. The resulting sludge cake is transported off-site for disposal. The supernatant from the sludge thickening tank and the wastewater from the sludge dewatering machine are returned to the upstream hydrolysis acidification tank and mixed with the wastewater from the tapping process for further treatment to avoid secondary pollution.

[0024] This invention separates the treatment of wastewater from cocoon boiling, silk reeling, and domestic wastewater, allowing for the extraction of sericin from the wastewater and reducing pollutant emissions while generating economic benefits. Utilizing the hydrolysis acidification tank's good resistance to shock loads and the high organic loading capacity of the UASB (Usage-Assisted Strains), it effectively treats the wastewater from cocoon boiling. The SBR (Sequencing-Batch Reactor) process is simple, has good treatment effects, flexible operation, stable and easily separated sludge properties, eliminates the need for secondary sedimentation tanks and sludge return equipment, and has low infrastructure costs and a small footprint.

[0025] By separating high-concentration cocoon washing wastewater from other low-concentration wastewater such as cocoon boiling wastewater, silk reeling wastewater, and re-reeling wastewater, the high-concentration wastewater is treated anaerobically before being mixed with other wastewater for aerobic treatment. This method not only ensures that the wastewater meets discharge standards but also facilitates the classification, extraction, and absorption of sericin from the wastewater.

[0026] Preferably, the grille includes a wall with an inlet. Guide supports extending into the sludge tank are fixed on both sides of the inlet. A lifting and tilting guide rail is provided on the guide support, and a basket grille is slidably connected to the lifting and tilting guide rail. A flat grille capable of blocking the inlet is provided above the inlet. Flat grille sliding rails are provided on both sides of the flat grille, and the flat grille is slidably connected to these rails. The sliding direction of the flat grille is the same as that of the basket grille. The side of the flat grille away from the wall is lower than the side of the lifting and tilting guide rail closest to the wall. Both the top of the basket grille and the top of the flat grille have hanging ears. A first pulley is provided at the end of the guide support, and a second pulley is provided on the inner side of the top of the guide support. A rope is threaded through the first pulley to pull the basket grille, and another rope is threaded through the second pulley to pull the flat grille.

[0027] This invention uses a lifting and tilting guide rail and the lugs on the basket screen to place it into a sludge tank for filtration. When the waste accumulates to a certain level, the basket screen is removed along the lifting and tilting guide rail to clean the waste inside. When the basket screen is removed from the sludge tank, the flat screen slides down along the flat screen sliding rail to block the inlet and perform filtration. After the basket screen has finished processing, it is placed back into the water, and the flat screen is pulled out from the inlet. When there is a lot of waste accumulated on the flat screen, it can also be pulled out for cleaning. This provides a screen that can operate continuously, allowing the screen system to keep working at all times.

[0028] Preferably, a limiting plate is provided at the bottom of the water inlet, a limiting block is provided at the bottom end of the lifting and tilting guide rail, the lifting and tilting guide rail is a U-shaped groove, and a blocking plate is symmetrically formed at the opening of the U-shaped groove. Rollers are provided on the basket grille, and the rollers slide within the U-shaped groove. This invention prevents excessive sliding by using the limiting plate and the limiting block.

[0029] Preferably, the bottom of the basket grid is funnel-shaped, which allows for the accumulation of more waste.

[0030] In summary, the beneficial effects of this invention are as follows: 1. This invention uses a lifting and tilting guide rail and the hanging ears on the basket screen to place the basket screen into the sludge tank for filtration. When the garbage accumulates to a certain level, the basket screen is removed along the lifting and tilting guide rail to clean the garbage inside. When the basket screen is removed from the sludge tank, the flat screen slides down along the flat screen sliding rail to block the inlet for filtration. After the basket screen has finished processing, it is placed in the water and the flat screen is pulled out from the inlet. When there is a lot of garbage accumulated on the flat screen, it can also be pulled out for cleaning. This provides a screen that can operate continuously, allowing the screen system to keep working. 2. In this invention, the silkworm cocoon separating screen frames, which are conveyed to the end of the second conveyor belt, slide onto the top of the transition plate via pulleys on the transition plate. The subsequent silkworm cocoon separating screen frames are then conveyed to the transition plate in sequence, causing the foremost silkworm cocoon separating screen frame to move forward. This moves all the silkworm cocoon separating screen frames on the conveyor belt to the top of the box. Then, pressing the push rod of the electric push rod moves it downward, thereby driving the pressing plate downward. All the silkworm cocoon separating screen frames and the transition plate are pressed below the water surface, and the boiling process begins. After completion, pressing the electric push rod drives the pressing plate back to its original position. Because the transition plate has a spring structure at the bottom, it can bring the silkworm cocoon separating screen frames out of the water surface after the transition plate loses pressure, thus completing the separation of silkworm cocoons and water. The silkworm cocoons after boiling can then be collected, thus completing the process of laying the silkworm cocoons flat and submerging them in boiling water. 3. In this invention, pressing the electric push rod downwards causes the rack to move downwards, which in turn causes the spur gear to rotate. The rotation of the spur gear causes the active bevel gear to rotate, which in turn causes the passive bevel gear to rotate, which in turn causes the rotating shaft to rotate. This causes the stirring paddle to start stirring. Through stirring, the temperature inside the chamber can be kept consistent from top to bottom and left to right, so that the cocoons inside the chamber can be heated evenly, reducing the phenomenon of the cocoons being partially cooked and shortening the cooking time. 4. This invention uses a lifting and tilting guide rail and the hanging ears on the basket screen to place the basket screen into the sludge tank for filtration. When the garbage accumulates to a certain level, the basket screen is removed along the lifting and tilting guide rail to clean the garbage inside. When the basket screen is removed from the sludge tank, the flat screen slides down along the flat screen sliding rail to block the inlet for filtration. After the basket screen has finished processing, it is placed in the water, and the flat screen is pulled out from the inlet. When there is a lot of garbage accumulated on the flat screen, it can also be pulled out for cleaning. This provides a screen that can operate continuously, allowing the screen system to keep working. Attached Figure Description

[0037] like Figure 14 As shown, the wastewater treatment unit 7 includes a continuously used screen 71, an equalization tank 72, an SBR tank 73, a sludge thickening tank 74, and a sludge dewatering machine 75, which are connected in sequence.

[0038] like Figure 7-13As shown, the grille 71 includes a wall 711 with an inlet 712. Guide supports 713, which extend into the sludge tank, are fixed on both sides of the inlet 712. A lifting and tilting guide rail 714 is provided on the guide support 713, and a basket grille 715 is slidably connected to the lifting and tilting guide rail 714.

[0039] Working principle: such as Figure 1-14 As shown, before preparation, water and alkaline substances are added to the tank. Then, the electric push rod 43 is pressed to move up and down, which causes the rack 87 to move up and down, driving the spur gear 86 to rotate clockwise or counterclockwise, driving the active bevel gear 89 to rotate clockwise or counterclockwise, which in turn drives the passive bevel gear 88 to rotate in both directions, thereby driving the rotating shaft 81 to rotate in both directions, thus causing the stirring paddle 84 to rotate and stir. Furthermore, the conical stirring tube 843 on the stirring paddle 84 generates turbulence at the cone end through acceleration, displacement and stagnation, and stirs the medium, thereby causing the fluid to flow, generating a new dynamic mixing motion, and accelerating the mixing speed. After the alkaline water is mixed, it is ready for use. Press the electric push rod 43 to return to its original position. The silkworm cocoons are vacuum permeated through vacuum tank 2. Then, the vacuum tank 2 is opened, and the cocoons and water are poured into the bottom filter frame 5. The cocoons remain in the filter frame 5, while the water flows to the bottom water tank 6. The outlet of the filter frame 5 is then opened, and the cocoons fall onto the vibrating discharge plate 31 through vibration. The vibrating discharge plate 31 then disperses the material. The material is then conveyed evenly by the first conveyor belt 32, and then spread evenly on the cocoon separating screen frames 34 by the second conveyor belt 33, ensuring that each cocoon separating screen frame 34 is covered with cocoons. As the second conveyor belt 33 moves forward, the cocoons are further distributed... The cocoon separating screen frame 34 at the end of the 3rd section slides onto the transition plate 42 via pulleys on the transition plate 42, and the subsequent cocoon separating screen frames 34 are sequentially conveyed onto the transition plate 42, causing the foremost cocoon separating screen frame 34 to move forward. This moves all the cocoon separating screen frames 34 on the conveyor belt to the top of the box 41. Then, pressing the push rod end of the electric push rod 43 downwards moves the pressing plate 44 downwards, pressing all the cocoon separating screen frames 34 and the transition plate below the water surface. This ensures that while the cocoons are submerged in the water, they are confined within the cocoon separating screen frame 34 with no extra space. The silkworm cocoons don't have a chance to tumble in boiling water, so they don't get too tangled. Then the boiling process begins. During boiling, pressing the electric push rod 43 causes a short, reciprocating motion, which in turn causes the rack 87 to move up and down, rotating the spur gear 86 clockwise or counterclockwise. This, in turn, rotates the driving bevel gear 89 clockwise or counterclockwise, which in turn rotates the driven bevel gear 88, causing the rotating shaft 81 to rotate in both directions. This, in turn, rotates the stirring paddle 84, ensuring a consistent temperature throughout the chamber. This allows the cocoons inside the chamber 41 to be heated evenly, further reducing the risk of uneven ripening. This process not only reduces the time required to boil the cocoons, but also shortens the boiling time. After boiling, pressing the electric push rod 43 drives the pressing plate 44 back to its original position. Because the transition plate 42 has a spring structure 45 below it, the transition plate 42 can carry the cocoon separating screen frame 34 out of the water after losing pressure, thus completing the separation of the cocoons and water. In this way, the boiled cocoons can be collected later. This completes the process of laying the cocoons flat and submerging them in boiling water, which not only improves the boiling efficiency, but also prevents the cocoons from being partially boiled, surface boiled, or spotted boiled during the boiling process. The wastewater in the water storage tank and the wastewater generated after boiling the cocoons are treated by the wastewater treatment mechanism to meet the discharge requirements, making it more environmentally friendly. In the wastewater treatment process, after the basket screen 715 accumulates a certain amount of garbage, it is removed along the lifting and tilting guide rail 714 to clean the garbage inside. When the basket screen 715 is removed from the sludge tank, the flat screen 716 slides down along the flat screen sliding rail 717 to block the inlet and perform filtration. After the basket screen 715 has finished processing, it is placed back into the water, and the flat screen 716 is pulled out from the inlet. When there is a lot of garbage accumulated on the flat screen 716, it can also be pulled out for cleaning. This provides a screen that can operate continuously, allowing the screen system to keep working and filtering thoroughly.
