Description

Technical Field

[0001] The invention relates to the field of cocoon boiling, and in particular to a highly efficient and environment-friendly cocoon boiling device. Background Art

[0002] Silkworm cocoons are the raw materials for silk production. The process of stripping cocoons to make raw silk is called silk production. The silk production process often includes drying cocoons, peeling cocoons, selecting cocoons, boiling cocoons, reeling, reshaping, and sorting. Dry cocoons cannot be directly peeled out of cocoons in sequence. Due to the unique way silkworms spin cocoons, the cocoons are arranged in "S" and "8" shapes, forming many cross-overlapping points, and the sericin content of the cocoon layer varies from the outside to the inside, making some cocoons more adhered and difficult to separate. After the cocoons are dried and stored, the sericin in the cocoon layer is more firmly adhered. At this time, the adhesive force between the cocoon silk greatly exceeds the cutting strength of the cocoon silk. Therefore, if the cocoon silk is directly extracted without boiling the cocoon, the cocoon silk will be cut and cannot be reeled.

[0003] Cocoon cooking is to use the effect of water and heat to swell and appropriately dissolve sericin, so that the cocoons can be smoothly peeled off from the cocoon layer in sequence during the reeling process. From a technological perspective, cocoon cooking can be divided into three processes: penetration, cooking, and adjustment and protection. Each process is a means of cocoon cooking, and its main role is penetration and cooking during cocoon cooking. Its purpose is to achieve uniform cooking between the cocoon layer and the cocoon particles. Cocoon cooking not only reduces the adhesive force of the cocoon silk, but also increases the wet strength of the cocoon silk, so that the adhesive force of the cocoon silk is much smaller than the cutting strength of the cocoon silk. While ensuring the smooth and sequential separation of the cocoon silk from the cocoon layer, it can also reduce the breakage caused by excessive cocoon jumping during the reeling process. The equipment for cooking cocoons is a cocoon cooking machine, which directly introduces a pile of cocoons into water for cooking, which is prone to uneven heating and piece-cooking (cooking differences between cocoons). At the same time, the water absorption capacity and water penetration capacity of cocoons are different, resulting in surface cooking (the cocoon layer is cooked outside and raw inside) and spot cooking (different parts of the cocoon grains are cooked unevenly). The cocoons of the existing cocoon cooking machine are all cooked while floating on the surface of the water, resulting in low cooking efficiency. The wastewater generated after cooking is not treated and is directly discharged, which is easy to pollute the environment. Therefore, it is necessary to propose an efficient and environmentally friendly cocoon cooking device. Summary of the invention

[0004] The purpose of the present invention is to solve the problems in the background technology and provide an efficient and environmentally friendly cocoon cooking device.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: A highly efficient and environmentally friendly cocoon cooking device comprises a frame, wherein the frame is provided with a vacuum tank, a cocoon separation and paving mechanism, and a cocoon soaking and cooking mechanism in sequence from left to right; a filter frame is further provided at the bottom of the vacuum tank; a water storage tank is provided at the bottom of the filter frame; waste water from the water storage tank and the cocoon soaking and cooking mechanism are connected to a wastewater treatment mechanism through a pipeline; there is no filter hole on the side of the filter frame close to the cocoon separation and paving mechanism to prevent water from flowing into the cocoon separation and paving mechanism; a discharging mechanism is provided on the discharging port of the filter frame; the discharging mechanism comprises a discharging electric push rod, a discharging plate is hinged at the push rod end of the discharging electric push rod, and a motor end of the discharging electric push rod is hinged to the filter frame so that the discharging plate can be automatically opened and closed by the electric push rod; the bottom of the filter frame is inclined so that the cocoons can smoothly enter the vibrating discharging plate.

[0006] The present invention performs vacuum penetration on silkworm cocoons through a vacuum tank, then opens the vacuum tank to pour the silkworm cocoons and water into a filter frame at the bottom, the silkworm cocoons are retained in the filter frame through the filter frame, and the water is retained in a water storage tank at the bottom, then the discharge port of the filter frame is opened, the silkworm cocoons are separated and laid in a silkworm cocoon separation screen frame through a silkworm cocoon separation and laying mechanism, and then enter into a silkworm cocoon soaking and boiling mechanism to be immersed in water for full boiling, which not only improves the water boiling efficiency, but also prevents the silkworm cocoons from being cooked in pieces, boiled on the surface and boiled in spots during the boiling process, the waste water in the water storage tank and the waste water generated after boiling are treated by a waste water treatment mechanism to meet the discharge requirements, and is more environmentally friendly.

[0007] Preferably, the cocoon separation and paving mechanism includes a vibrating discharge plate, a first conveyor belt, a second conveyor belt, and a cocoon separation screen frame. A discharge port is opened on the right side of the filter frame, and the vibrating discharge plate is tilted on 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 separation screen frames are placed in sequence on the second conveyor belt in close array. The vibrating discharge plate is in a triangular shape with a gradually decreasing width from the starting end to the end, so that the cocoons can enter the first conveyor belt in turn, which is beneficial to the subsequent paving work. Baffle plates are provided on both sides of the vibrating discharge plate to prevent materials from falling from both sides. The vibrating discharge plate is controlled by an existing vibration motor, which is a very mature technology, so it will not be repeated in this case. In order to better vibrate the material, a vibration motor can also be provided on the filter frame.

[0008] The present invention disperses the material by vibrating a discharging plate, then distributes the material by a first conveyor belt, and then spreads the material on a cocoon separation screen frame by a second conveyor belt, thereby completing the function of spreading and separating the cocoons.

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

[0010] The present invention enables the cocoon separation screen frame transmitted to the end of the second conveyor belt to slide into the top of the transition plate through the pulley on the transition plate, and the cocoon separation screen frames at the rear are transmitted to the transition plate in turn, so that the cocoon separation screen frame located at the front end moves forward, thereby moving all the cocoon separation screen frames on the conveyor belt to the top of the box body, and then pressing the push rod end of the electric push rod to move downward, thereby driving the pressing plate to move downward, pressing all the cocoon separation screen frames and the transition plate to below the water surface, and then starting the water boiling work. After completion, pressing the electric push rod to drive the pressing plate to return to its position, because a spring structure is provided under the transition plate, the transition plate can carry the cocoon separation screen frame out of the water after losing pressure, thereby completing the separation of the cocoons and water, and later collecting the boiled cocoons, thereby completing the cocoon flattening and immersion boiling.

[0011] Preferably, two spring structures are stacked, and the spring structure includes a compression spring, an upper fixing plate, a lower fixing plate, and a silicone protective cover. The upper fixing plate is arranged on the top of the compression spring, and the lower fixing plate is arranged on the bottom of the compression spring. The upper fixing plate and the lower fixing plate are provided with a clamping block on the side away from the compression spring, and the box body and the transition plate are provided with a clamping groove that cooperates with the clamping block. The silicone protective cover is fixed on the outside of the compression spring, and a closed space is formed between the silicone protective cover, the upper fixing plate and the lower fixing plate, and the compression spring is located in the closed space.

[0012] The present invention can fix the spring structure through the clamping block and the clamping slot. In order to enhance the firmness, glue can be applied between the clamping block and the clamping slot.

[0013] The present invention ensures that the compression spring can work normally through the silicone protective cover, and can prevent impurities from entering the compression spring. If there are impurities on the compression spring, the presence of the impurities may interfere with the elasticity and movement of the spring and affect the reciprocating motion of the transition plate. The impurities will cause the spring to experience greater resistance during compression and extension, reduce the reaction speed and sensitivity of the spring, and thus affect the reciprocating motion of the transition plate.

[0014] Preferably, the top of the silicone protective cover is formed with an upper through groove that can be inserted into the card block, the bottom of the silicone protective cover is formed with a lower through groove that can cover the lower fixing plate, the top of the silicone protective cover and the bottom of the inner wall are both formed with silicone clamping rings, and the upper fixing plate and the lower fixing plate are both formed with annular limiting grooves that cooperate with the silicone clamping rings, and the sealing is enhanced by the silicone clamping rings and the annular limiting grooves.

[0015] Preferably, a temperature stirring mechanism is provided in the box body, and the temperature stirring mechanism includes a rotating shaft, a first bearing, a second bearing, a stirring paddle, a fixed rod, a spur gear, a rack, a passive bevel gear, and an active bevel gear. The bottom of the rotating shaft is rotatably connected to the box body through the first bearing, the passive bevel gear is fixed to the top of the rotating shaft, the active bevel gear is meshed with the moving bevel gear, the middle part of the active bevel gear is fixedly connected to the fixed rod, the spur gear sleeve is fixed on the fixed rod, the rack is meshed with the spur gear, the top of the rack is fixedly connected to the bottom of the transition plate, the stirring paddle is arranged 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 box body, and the connection between the second bearing and the box body can be through a bracket. This fixing method is very mature, so it is not repeated in this case. The liquid can be heated by a heating wire in the box body.

[0016] The present invention presses the electric push rod downward to drive the rack to move downward, thereby driving the spur gear to rotate. The rotation of the spur gear drives the active bevel gear to rotate, thereby driving the passive bevel gear to rotate, thereby driving the rotating shaft to rotate, so that the stirring paddle starts stirring. Through the stirring method, the temperatures up and down, left and right in the box can be kept consistent, so that the cocoons in the box can be heated evenly, the phenomenon of the cocoons being cooked in pieces is reduced, and the steaming time is shortened.

[0017] The electric push rod can be pressed to reciprocate up and down, so that the rack can reciprocate up and down, so that the stirring paddle can stir forward and reverse, and can stir continuously, and the temperature in the box can be kept consistent from top to bottom and left to right.

[0018] Preferably, the stirring paddle includes a connecting rod, stirring blades, and a conical stirring tube. More than three 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 obliquely fixed on the side wall of the rotating shaft, and the large-diameter end of the conical stirring tube is tilted downward by 10°-15°.

[0019] The conical stirring tube of the present invention generates turbulence at the cone end through acceleration, displacement and blockage, and stirs the medium, thereby making the fluid 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 be used in the early stage to make the alkaline substances and liquids stir evenly, but also can be used in the later stage to keep the temperature in the box uniform.

[0020] Preferably, the wastewater treatment mechanism includes a grid, a regulating tank, an SBR tank, a sludge thickening tank, and a sludge dewatering machine which are connected in sequence and used continuously.

[0021] The cocoon cooking wastewater, silk reeling wastewater and domestic wastewater enter the screen well together. After being intercepted by the screen to remove large particles and floating objects in the wastewater, it enters the regulating tank. After being mixed with the UASB effluent in the regulating tank to homogenize the water quality, it enters the SBR tank. In the water inlet stage, the wastewater enters the reaction tank and is fully mixed with the activated sludge through the agitator. The microorganisms in the activated sludge begin to adsorb the organic matter in the wastewater; through aeration, the activated sludge begins to degrade the organic matter in the wastewater, and the nitrification reaction begins at the same time, converting the ammonia nitrogen in the wastewater into nitrate nitrogen and nitrite nitrogen, and the indicators such as COD, BOD and ammonia nitrogen in the wastewater are reduced; precipitation begins after aeration stops. With the continuous consumption of dissolved oxygen, the system gradually turns from the aerobic stage to the anoxic stage, and finally to the anaerobic stage, and denitrification and denitrification begin. Finally, the SBR supernatant is discharged after reaching the discharge concentration requirements of Table 1 of the "Silk Reeling Industry Water Pollutant Discharge Standard" (GB28936-2012) through the decanter.

[0022] The wastewater from the first stage of the wastewater first enters the primary sedimentation tank, where sericin, fibroin, crude protein and broken pupae are mostly precipitated and removed, and the pH is adjusted to between 7 and 9. The effluent from the primary sedimentation tank is pumped into the pressure gas tank by a pressure pump, and then pumped into the flotation tank with the reflux clarified liquid under pressure, and PAC and PAM are added as coagulants to further remove suspended matter and oils. The effluent from the flotation tank flows into the hydrolysis and acidification tank, where the large molecules and difficult-to-biodegrade organic matter in the wastewater are hydrolyzed and converted into small molecules and easily biodegradable soluble organic matter through the hydrolysis and acidification of facultative anaerobic microorganisms, thereby improving the biodegradability of the wastewater, removing part of the COD and BOD, and playing a role in homogenizing the water quality to a certain extent. The effluent from the hydrolysis and acidification tank is pumped to the UASB anaerobic reactor, where most of the organic matter in the wastewater is degraded into CH4, CO2, H2O or converted into cell bodies through the degradation and conversion of anaerobic granular sludge, effectively reducing the COD and BOD indicators of the wastewater. The UASB effluent flows by gravity into the regulating tank.

[0023] The sediment in the primary sedimentation tank is mainly sericin, fibroin, crude protein and broken pupae, which can be extracted by classification after treatment; the floating scum in the flotation tank and the residual sludge of UASB and SBR are concentrated by gravity in the sludge thickening tank, and then pumped into the sludge dewatering machine for dehydration, and the mud cake produced is transported out for disposal. The supernatant of the sludge thickening tank and the sewage removed from the sludge dewatering machine are returned to the front hydrolysis acidification tank and mixed with the wastewater before treatment to avoid secondary pollution.

[0024] The present invention treats the wastewater from cocoon cooking, silk reeling and domestic wastewater separately, so that sericin in the wastewater can be extracted by classification, reducing pollutant emissions while generating certain economic benefits; the good impact load resistance of the hydrolysis acidification tank and the high organic load of the UASB are utilized to effectively deal with the treatment of the wastewater from cocoon cooking. The SBR tank has a simple process flow, good treatment effect, flexible operation mode, stable sludge properties and easy separation, no secondary sedimentation tank and sludge return equipment are required, low infrastructure cost and small land occupation.

[0025] The high-concentration wastewater from cocoon cooking, silk reeling and re-shaking is separated by clear and turbid separation. The wastewater from cocoon cooking is treated anaerobic and then mixed with other wastewater for aerobic treatment. This method can not only meet the discharge standards, but also facilitate the classification, extraction and absorption of sericin in wastewater.

[0026] Preferably, the grille includes a wall, a water inlet is provided on the wall, guide brackets that can extend into the sludge pool are fixed on both sides of the water inlet, a lifting and flipping guide slide rail is provided on the guide bracket, a basket grille is slidably connected to the lifting and flipping guide slide rail, a flat grille that can block the water inlet is provided above the water inlet, flat grille sliding rails are provided on both sides of the flat grille, the flat grille is slidably connected on the flat grille sliding rails, the sliding direction of the flat grille is the same as the sliding direction of the basket grille, the side of the flat grille away from the wall is lower than the side of the lifting and flipping guide slide rail close to the wall, the top of the basket grille and the top of the flat grille are both provided with hanging ears, a first pulley is provided at the end of the guide bracket, a second pulley is provided on the inner side of the top of the guide bracket, a rope is passed through the first pulley to pull the basket grille, and a rope is passed through the second pulley to pull the flat grille.

[0027] The present invention places the basket grille into the sludge pool for filtration by lifting and flipping the guide slide rail and the hanging ears on the basket grille. When the garbage accumulates to a certain extent, the basket grille is taken out along the lifting and flipping guide slide rail to clean the garbage in the basket grille. When the basket grille is taken out of the sludge pool, the flat grille slides downward along the flat grille sliding rail to block the water inlet for filtering. When the basket grille is processed, the basket grille is placed in water and the flat grille is pulled out of the water inlet. When a lot of garbage accumulates on the flat grille, it can also be pulled out for cleaning, thereby providing a grille that can function uninterruptedly, so that the grille system can keep working all the time.

[0028] Preferably, a limit plate is provided at the bottom of the water inlet, a limit block is provided at the bottom end of the lifting and flipping guide rail, the lifting and flipping guide rail is a U-shaped groove, a blocking plate is symmetrically formed at the opening of the U-shaped groove, and a roller is provided on the basket grille, and the roller slides in the U-shaped groove. The present invention prevents the basket from sliding too far down by using the limit plate and the limit block.

[0029] Preferably, the bottom of the basket grille is funnel-shaped, which can accumulate more garbage.

[0030] In summary, the beneficial effects of the present invention are: 1.

When the basket grille is processed, the basket grille is placed in water and the flat grille is pulled out from the water inlet. When a lot of garbage accumulates on the flat grille, it can also be pulled out for cleaning, thereby providing a grille that can function uninterruptedly, so that the grille system can keep working all the time; 2. The present invention uses the pulley on the transition plate to make the cocoon separation screen frame transmitted to the end of the second conveyor belt slide into the top of the transition plate through the pulley, and the rear cocoon separation screen frame is transmitted to the transition plate in turn, so that the cocoon separation screen frame located at the front end moves forward, thereby moving all the cocoon separation screen frames on the conveyor belt to the top of the box body, and then pressing the push rod end of the electric push rod to move downward, thereby driving the pressing plate to move downward, pressing all the cocoon separation screen frames and the transition plate to the bottom of the water surface, and then starting the water boiling work. After completion, pressing the electric push rod to drive the pressing plate back to its position, because a spring structure is provided under the transition plate, the transition plate can carry the cocoon separation screen frame out of the water after losing pressure, thereby completing the separation of cocoons and water, and later collecting the boiled cocoons, thereby completing the cocoon flattening and immersion boiling; 3.

[0039] Working principle: Figure 1-14 As shown, before preparation, water and alkaline substances are added into the box, and then the electric push rod 43 is pressed to reciprocate up and down, so that the rack 87 reciprocates up and down, drives the spur gear 86 to rotate clockwise or counterclockwise, drives the active bevel gear 89 to rotate clockwise or counterclockwise, thereby drives the passive bevel gear 88 to rotate forward and reversely, thereby drives the rotating shaft 81 to rotate forward and reversely, so that the stirring paddle 84 rotates and stirs, and further the conical stirring tube 843 on the stirring paddle 84 generates turbulence at the cone end through acceleration, displacement and blockage, and stirs the medium, so that the fluid flows, generates a new dynamic mixing motion, speeds up the mixing speed, and the alkali water is mixed and ready for use, and the electric push rod 43 is pressed to return to its original position; The cocoons are vacuum-infiltrated through the vacuum tank 2, and then the vacuum tank 2 is opened to pour the cocoons and water into the filter frame 5 at the bottom, so that the cocoons remain in the filter frame 5 through the filter frame 5, and the water remains in the water storage tank 6 at the bottom, and then the discharge port of the filter frame 5 is opened, and the cocoons fall into the vibrating discharge plate 31 through vibration, and then the vibrating discharge plate 31 vibrates the material, and then it is transported by the first conveyor belt 32 for uniform material, and then it is spread on the cocoon separation screen frame 34 through the second conveyor belt 33, so that each cocoon separation screen frame 34 is spread with cocoons, and as the second conveyor belt 33 moves forward, the cocoons located on the second conveyor belt 3 The cocoon separation screen frame 34 at the end of the conveyor belt 3 slides into the top of the transition plate 42 through the pulley on the transition plate 42, and the cocoon separation screen frame 34 behind is sequentially transferred to the transition plate 42, so that the cocoon separation screen frame 34 located at the front end moves forward, thereby moving all the cocoon separation screen frames 34 on the conveyor belt to the top of the box body 41, and then the push rod end of the electric push rod 43 is pressed downward to drive the pressing plate 44 to move downward, and all the cocoon separation screen frames 34 and the transition plate are pressed below the water surface, so that the cocoons are immersed in the water, and the cocoons are confined in the cocoon separation screen frame 34, leaving no extra space The cocoons have no chance to roll in the boiling water, and will not be tangled too seriously. Then the water boiling work begins. During the boiling process, the electric push rod 43 is pressed to move up and down for a short distance, so that the rack 87 moves up and down, drives the spur gear 86 to rotate clockwise or counterclockwise, drives the active bevel gear 89 to rotate clockwise or counterclockwise, drives the passive bevel gear 88 to rotate forward and reverse, drives the rotating shaft 81 to rotate forward and reverse, and the stirring paddle 84 rotates and stirs, so that the temperature of the box body can be kept consistent, so that the cocoons in the box body 41 can be heated evenly, and the cocoons can be further reduced. The phenomenon of cocoon boiling is reduced, and the cocoon boiling time is shortened. After the cocoon boiling is completed, the electric push rod 43 is pressed to drive the pressing plate 44 to return to its original position. Since a spring structure 45 is provided under the transition plate 42, the transition plate 42 can carry the cocoon separation screen frame 34 out of the water after losing pressure, so that the cocoons and water can be separated. In this way, the cocoons after boiling can be collected later, so that the cocoons are laid flat and immersed in water for boiling, which not only improves the boiling efficiency, but also prevents the cocoons from being cooked in pieces, boiled on the surface and boiled in spots during the cocoon boiling process. The wastewater in the water storage tank and the wastewater generated after cocoon boiling are treated by the wastewater treatment mechanism to meet the discharge requirements, which is more environmentally friendly. During the sewage treatment process, when the garbage in the basket grille 715 accumulates to a certain extent, the basket grille 715 is taken out along the lifting and flipping guide slide rail 714 to clean the garbage in the basket grille 715. When the basket grille 715 is taken out from the sludge pool, the flat grille 716 slides down along the flat grille sliding rail 717, thereby blocking the water inlet for filtering. When the basket grille 715 is processed, the basket grille 715 is placed in water and the flat grille 716 is pulled out of the water inlet. When a lot of garbage accumulates on the flat grille 716, it can also be pulled out for cleaning, thereby providing a grille that can function uninterruptedly, so that the grille system can keep working and filter fully.
