Description

Technical Field

[0001] This invention belongs to the technical field of cocoon boiling devices, specifically an automatic pressure-reducing cocoon boiling device. Background Technology

[0002] Reeling fresh cocoons and boiling them are crucial steps in silk production. Reeling involves extracting silk threads from freshly harvested cocoons, usually done immediately after cocoon production to maintain the freshness and quality of the silk. The cocoon shell is softened with hot water or chemicals, and then a reeling machine extracts the silk into a continuous thread. Before reeling, the cocoons are heated in hot water to soften and crack the shell, facilitating reeling. Boiling the cocoons requires precise temperature and time control to ensure complete softening of the silk while avoiding damage that could affect quality.

[0003] A Chinese patent with publication number CN104480539A discloses a cocoon reeling and boiling machine. This machine includes a pot with an inlet and an outlet. Inside the pot are a feed cylinder driven by a motor and a temperature sensor. The pot includes an inner layer and an outer layer, with a heater positioned between them. A door corresponding to the feed cylinder opening is located on the pot. The temperature sensor, the heater, and the motor are electrically connected to a controller. The feed cylinder has a rotating shaft passing through the pot, and this shaft is connected to the motor's output shaft via a pulley. This invention solves the problem of uneven heating of silkworm cocoons, which prevents the extraction of silk and affects production.

[0004] Most existing cocoon boiling devices lack automatic pressure reduction functions, resulting in insufficient operational flexibility and difficulty in effectively adapting to the boiling requirements under different working conditions. This limitation prevents the sericin in the cocoon silk from fully swelling and dissolving, and the adhesive points cannot be effectively opened, thus affecting the subsequent cleaning and purifying effects. In addition, insufficient sericin viscosity seriously affects the cohesion quality of the silk threads, making it difficult to guarantee product quality. The loss of cocoon material during the fresh cocoon reeling process is relatively large, and the production efficiency and potential have not been fully explored and utilized. These problems seriously restrict the optimization and improvement of the process, and the equipment design needs to be improved to achieve higher operational flexibility and processing effects.

[0005] Therefore, the present invention provides an automatic pressure-reducing cocoon boiling device. Summary of the Invention

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 7 As shown in the embodiment of the present invention, an automatic pressure-reducing cocoon boiling device includes a base plate 1. A main tank 2 and an auxiliary tank 3 are symmetrically arranged on the base plate 1. Support legs 4 are fixedly connected to both the main tank 2 and the auxiliary tank 3, and the support legs 4 are fixedly connected to the base plate 1. A water pump 7 and a vacuum pump 8 are symmetrically arranged on the base plate 1. The input end of the water pump 7 is connected to the top of the main tank 2 via a pipe, and the output end of the water pump 7 is connected to the bottom of both the main tank 2 and the auxiliary tank 3 via pipes. The input end of the vacuum pump 8 is connected to the bottom of both the main tank 2 and the auxiliary tank 3 via pipes. The vacuum pump 8 is connected to the top of the auxiliary tank 3 via a pipe. A drain pump 24 is fixedly installed on the top of the base plate 1. The output of the drain pump 24 is connected to the main tank 2 and the auxiliary tank 3 via pipes. The main tank 2 is equipped with a spray mechanism and a dispersion mechanism. When using the automatic pressure-reducing cocoon-cooking device to cook fresh cocoons, the cocoons to be processed are placed inside the main tank 2 and the auxiliary tank 3. Solenoid valves and flow meters are installed on the pipes connected to the water pump 7, vacuum pump 8, and drain pump 24. The meter is electrically connected to the controller 10. It can control pipeline closure via a solenoid valve and monitor flow parameters. Using a single-chip microcomputer program control, it can achieve fully enclosed and automated operation of the cocoon boiling process, completing the vacuum permeation of silkworm cocoons. It can intelligently control the operation of the solenoid valve. Sensors are installed inside the main tank 2 and auxiliary tank 3 to monitor data such as temperature and pressure inside the main tank 2 and auxiliary tank 3. The boiling point of water decreases as the vacuum level increases. Under a certain vacuum level, water can evaporate and boil at a lower temperature. By increasing the kinetic energy of water molecules, the main tank 2 and auxiliary tank 3 apply this principle and use a "vacuum + steam" method in the water discharge process. The main tank 2 and auxiliary tank 3 adopt a bidirectional steam inlet pipe design. During the water discharge period, through program design, different combinations of steam entering from the top and vacuum being drawn from the bottom, or steam entering from the bottom and vacuum being drawn from the top, are used to form a negative pressure state, which lowers the boiling point of water and achieves low-temperature water discharge. The vacuum lowers the boiling point of water, and the steam provides heat energy to the cocoons. The water discharge temperature in the cocoon cavity is more than 20°C lower than that of traditional technology, which effectively controls the sericin loss rate. Fresh cocoons are boiled and steamed under a certain vacuum, which significantly reduces the boiling temperature of the water. Heat transfer is carried out by convection under negative pressure, which improves the heat exchange capacity and uniformity of steam. After the fresh cocoons are permeated by vacuum, the cocoon cavity is filled with a large amount of low-temperature water, which is generally between 28 and 35°C. At this time, the cocoon layer is moistened and there is a certain amount of water in the gaps between the cocoon layers, but it has not penetrated into the sericin molecules. It is necessary to expel the water under certain energy conditions to increase the swelling degree of the cocoon layer. Simply using a higher vacuum can also expel the water from the cocoon cavity, but since there is no heat energy, it only plays a reverse osmosis role and does not achieve the purpose of swelling the sericin. Therefore, the "vacuum + steam" method is used in the process of expelling water and steaming cocoons under reduced pressure. During the process of water expulsion from fresh cocoons, the vacuum degree varies within the range of 0→-0.06→-0.085→-0.093→-0.095→-0.06 MPa, while the temperature gradually increases from 36→44→52→68℃. Particularly after the peak water expulsion, the temperature rises rapidly and the vacuum degree decreases. Based on the correlation between the boiling point of water and vacuum degree, the higher the vacuum degree, the lower the boiling point of water. During the depressurized cocoon boiling and water expulsion process, under the implementation of "vacuum + steam," the water in the cocoon cavity is in a boiling state. The boiling and vaporization effect increases the kinetic energy of water molecules, and as the temperature increases, the water in the cocoon cavity is expelled. Long-term process testing shows that dry cocoons can completely expel water at 75℃ and fresh cocoons at below 70℃, meeting the process requirements. At these temperatures, water expulsion does not lead to a large loss of sericin. The water expulsion status can be observed through sight glasses 6 (upper and lower). After the water is expelled, the program enters the steaming sequence. During the steaming process, the tank has a certain degree of vacuum. The steam sent in flows in the tank to form thermal convection, which can quickly enter the cocoon and inner layer. The steaming temperature can reach 90~100℃. Since there is no water medium in the cocoon cavity, the sericin will not dissolve in large quantities. The sericin is fully swollen, which can cook the cocoon layer evenly. The main tank 2 and auxiliary tank 3 are controlled by a single-chip microcomputer program. The cocoon cooking process is fully enclosed, with an integrated structure of vacuum penetration and cocoon cooking, and automated operation. It completes the cocoon cooking process and procedures such as vacuum penetration of cocoons, bidirectional decompression and water discharge of cocoon cavity, bidirectional decompression steaming of cocoons, cooking balance, and adjustment and protection. The "vacuum + steam" method lowers the water discharge temperature and effectively controls the sericin loss rate. Negative pressure steaming is performed in a water-free cocoon cavity, allowing steam heat energy to quickly penetrate the middle and inner layers of the fresh cocoon through thermal convection, achieving uniform cooking of the cocoon layers and ensuring the sericin is fully and evenly swollen and softened. Production verification shows that the reduced-pressure automatic cocoon cooking machine significantly improves the cleanliness, purity, and cohesion of the raw silk produced after soaking, breaking through the quality bottleneck of fresh cocoon silk. This allows the fresh cocoon silk to be used in high-end silk fabric production, significantly improving the overall efficiency per ton of fresh cocoon silk. The simultaneous circulation of steam and negative pressure air or water facilitates water discharge and absorption, improving work efficiency. The drainage pump 24 operates by pumping and discharging water from the main tank 2 and the auxiliary tank 3 through pipelines.

[0024] Furthermore, both the main tank 2 and the auxiliary tank 3 are symmetrically equipped with viewing mirrors 6, which are divided into upper and lower viewing mirrors to facilitate viewing of the internal environment.

[0025] Furthermore, both the main tank 2 and the auxiliary tank 3 are equipped with a feed inlet 5, which facilitates the addition of silkworm cocoons into the main tank 2 and the auxiliary tank 3.

[0026] Furthermore, the water pump 7 and the vacuum pump 8 are electrically connected to the controller and are controlled by a single-chip microcomputer program. The cocoon boiling process is fully enclosed, with an integrated structure of vacuum penetration and cocoon boiling, and automated operation, completing the vacuum penetration of silkworm cocoons.

[0027] Furthermore, a bracket 9 is fixedly installed on the base plate 1, and a controller 10 is fixedly installed on the bracket 9. The controller 10 is electrically connected to the water pump 7 and the vacuum pump 8 respectively. The base plate 1 provides installation space for the controller 10 through the bracket 9. The controller 10 can control the operation of the automatic pressure reducing cocoon boiling device through a microcontroller program.

[0028] Furthermore, the heat recovery mechanism includes a frame 11, a heat absorption component, a conveying component, and a heat storage component. The frame 11 is fixedly installed on both the main tank 2 and the auxiliary tank 3. The heat storage component is located inside the frame 11, the heat absorption component is located inside the frame 11, and the conveying component for conveying the heat absorption medium is located inside the frame 11. The frame 11 provides installation space for the heat absorption component, the conveying component, and the heat storage component. Through the cooperation of the heat absorption component, the conveying component, and the heat storage component, heat can be recovered.

[0029] Furthermore, the heat absorption assembly includes an arc-shaped plate 12 and a heat absorption pipe 13. The arc-shaped plate 12 is fixedly mounted on the frame 11, and one side of the arc-shaped plate 12 is attached to the corresponding main tank 2 and auxiliary tank 3. The heat absorption pipe 13 is arranged around the inside of the arc-shaped plate 12. When the temperature inside the main tank 2 and auxiliary tank 3 rises, heat will be transferred to the arc-shaped plate 12, and then to the heat absorption pipe 13. When the heat absorption medium flows inside the heat absorption pipe 13, heat can be recovered and reused, reducing resource waste, improving energy utilization efficiency, reducing operating costs, reducing energy waste, reducing carbon emissions, and benefiting environmental protection. The recovered waste heat can be used to preheat raw materials or other auxiliary materials, saving energy.

[0030] Furthermore, the conveying assembly includes a mounting frame 14 and a pump 15. The mounting frame 14 is fixedly installed inside the frame 11, and the pump 15 is fixedly installed inside the mounting frame 14. The output end of the mounting frame 14 is connected to one end of the heat absorption pipe 13. The pump 15 is electrically connected to the controller 10. When the pump 15 is working, it will extract and convey the heat absorption medium stored inside the heat storage tank 16, so that the heat absorption medium flows into the heat absorption pipe 13. After heat absorption, the medium will flow back into the heat storage tank 16 for storage through the heat absorption pipe 13.

[0031] Furthermore, the thermal storage component includes a thermal storage box 16, a filling pipe 17, and a drain pipe 18. The thermal storage box 16 is fixedly installed inside the frame 11, the filling pipe 17 is fixedly installed on the top of the thermal storage box 16, one end of the drain pipe 18 is connected to the thermal storage box 16, and one end of the heat absorption pipe 13 is connected to the thermal storage box 16. The filling pipe 17 facilitates the filling of heat absorption medium into the thermal storage box 16, and the drain pipe 18 facilitates the discharge of the medium stored inside the thermal storage box 16.

[0032] Furthermore, the spraying mechanism includes a water supply pipe 19 and spray heads 20. The water supply pipe 19 is installed on the top of the inner wall of the main tank 2, and the spray heads 20 are arranged in an array on the water supply pipe 19. The water supply pipe 19 is connected to the pipeline. When the automatic pressure reducing cocoon cooking device is cooking the cocoons, the water pump 7 works to draw and transport water, and the water source flows into the interior of the water supply pipe 19. The spray heads 20 will spray the cocoons below, which can evenly spray water to cook the cocoons, so that the cocoons are evenly heated and processed.

[0033] Furthermore, the dispersing mechanism includes an annular shell 21, a screening screen 22, and a grid plate 23. The annular shell 21 is installed inside the main tank 2 and is located below the spray head 20. The screening screen 22 is fixedly installed inside the annular shell 21, and the grid plate 23 is fixedly installed inside the annular shell 21 and is located below the screening screen 22. The annular shell 21 is detachably installed inside the main tank 2. When boiling cocoons, after a bag of cocoons is poured into the main tank 2, the cocoons are dispersed by the screening screen 22 to prevent the cocoons from clumping together and causing uneven heating. After the cocoons are dispersed, the grid plate 23 supports them, allowing for even heating and processing during boiling. This improves work efficiency. After boiling, the annular shell 21 is removed from the main tank 2, and the boiled cocoons can be collected and transferred.

[0034] Working Principle: Firstly, when using the automatic pressure-reducing cocoon-cooking device to steam and cook fresh cocoons, the cocoons to be processed are placed inside the main tank 2 and auxiliary tank 3. Solenoid valves are installed on the pipes connected to the water pump 7 and vacuum pump 8. The process is controlled by a single-chip microcomputer program, featuring a fully enclosed, integrated vacuum penetration and cocoon-cooking structure, and automated operation. Vacuum penetration of the cocoons is completed, and the operation of the solenoid valves can be intelligently controlled. Sensors are installed inside the main tank 2 and auxiliary tank 3 to monitor data such as temperature and pressure. The boiling point of water decreases as the vacuum level increases. Under a certain vacuum level, water can evaporate and boil at a lower temperature, thereby increasing the kinetic energy of water molecules. The main tank 2 and auxiliary tank 3 utilize this principle, employing a "vacuum + steam" method in the water discharge process. The main tank 2 and auxiliary tank 3 feature a bidirectional steam inlet design. During the water discharge period, the program design controls the pressure on the main tank of the pressure-reducing cocoon-cooking machine. Different combinations of steam inlet and bottom vacuum, or bottom steam inlet and top vacuum, create a negative pressure state, lowering the boiling point of water and achieving low-temperature water discharge. The vacuum lowers the boiling point of water, and the steam provides heat energy to the silkworm cocoons. The water discharge temperature in the cocoon cavity is more than 20°C lower than that of traditional technology, effectively controlling the sericin loss rate. When the internal temperature of the main tank 2 and auxiliary tank 3 rises, the heat is transferred to the arc plate 12, and then to the heat absorption pipe 13. The pump 15 operates to extract and transfer the heat-absorbing medium stored in the heat storage box 16, causing the heat-absorbing medium to flow into the heat absorption pipe 13. After heat absorption, the medium flows back into the heat storage box 16 through the heat absorption pipe 13 for storage.
