Description

Technical Field

[0001] This utility model belongs to the technical field of sealed steam conveying structure, specifically, it relates to a flexible sealed steam conveying structure for an upper steaming cover used in distillation of alcoholic beverages. Background Technology

[0002] In the distillation industry, the top steam cover sealing structure is a crucial component of the entire distillation equipment, and its performance directly affects distillation efficiency, product quality, and the stability of the production process. Traditionally, top steam cover sealing structures used in distillation employ rigid stainless steel or bamboo pipes for steam delivery. Due to the lack of flexibility in rigid pipes, a water seal is necessary to allow the top steam cover to move laterally. However, water seals suffer from drawbacks such as incomplete sealing, easy vapor leakage, and the need for frequent water replenishment. The working principle of a water seal structure utilizes the sealing properties of water. An annular water trough is placed at the connection between the top steam cover and the still, immersing the edge of the top steam cover in water to form a water-sealed barrier. This prevents vapor leakage from the connection, ensuring that the vapor can be smoothly delivered through the steam delivery pipe to the cooling tank for cooling and condensation.

[0003] However, this traditional water seal structure has many drawbacks. First, the range of motion of the water seal structure is greatly limited, allowing only horizontal movement and preventing flexible actions such as raising and lowering the upper lid. In actual production, operators may need to check, add, or adjust the materials in the still according to different distillation process requirements. The fixed water seal structure makes it difficult for the upper lid to meet diverse operational needs, increasing operational difficulty and reducing work efficiency. Second, the sealing effect of the water seal structure is unstable. As the distillation process continues, the water in the water seal tank will continuously decrease due to high-temperature evaporation and vapor carryover. If water is not replenished in time, the sealing performance will decline, leading to vapor leakage, which not only wastes raw materials but also reduces the yield and quality of the liquor. Moreover, after a period of use, dirt and impurities easily accumulate in the water tank, affecting the sealing effect and requiring frequent cleaning and maintenance, increasing labor and equipment maintenance costs. Furthermore, traditional steam valves are usually located at the bottom of the cooling tank, a design with significant flaws. Due to the uneven thickness and density of the mash in the still, the heat and steam generation during distillation will also be uneven. When the steam valve is located at the bottom of the cooling tank, it is impossible to adjust the amount of steam entering the cooling tank in a timely and accurate manner according to the actual condition of the mash. Utility Model Content

[0004] In view of this, the present invention provides a flexible sealing steam conveying structure for the upper steam cover used in distillation, which solves the drawbacks of unreasonable steam valve settings in the traditional upper steam cover sealing steam conveying structure and improves the efficiency of steam regulation.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a flexible sealing steam conveying structure for a top steaming lid in distillation, comprising a still, a top steaming lid, a chuck, a flexible hose, a sealing part, a cooling tank, and a lid locking device. The top steaming lid is positioned on top of the still, the chuck is positioned on top of the top steaming lid, one end of the flexible hose is connected to the chuck, and the other end is connected to the sealing part, which is connected to the cooling tank. A sealing ring is provided inside the sealing part. The lid locking device is located at the connection between the still and the top steaming lid, and is used to tightly fix the top steaming lid to the still.

[0007] The combination of a chuck and a flexible hose replaces the traditional water seal structure, and the upper distillation lid can be raised and lowered via the flexible hose. The flexible hose is made of a high-temperature resistant and highly sealing material, maintaining stable physical properties under high-temperature distillation conditions. Its smooth, wrinkle-free interior ensures the steam passes smoothly in pure gaseous form, preventing condensation into liquid water due to rough inner walls or material defects. This guarantees the efficiency and purity of vapor delivery during distillation.

[0008] The high sealing performance of the flexible hose, along with its design in conjunction with the chuck and sealing components, creates a completely sealed steam transport environment, ensuring that the pipeline always carries pure gaseous vapor and preventing liquid water from contaminating and affecting the distillation effect. The combination of the chuck and flexible hose replaces the traditional water seal structure, overcoming the limitation of the water seal structure's horizontal movement and allowing the upper distillation lid to move up and down, greatly improving the flexibility of the device's operation. The lid locking device securely fixes the upper distillation lid to the still, effectively solving the problem of lid leakage, improving the sealing performance during distillation, ensuring sufficient vapor delivery, and enhancing distillation efficiency and product quality.

[0009] Based on the above technical solution, the flexible sealing steam conveying structure of the upper steaming lid for distillation of alcoholic beverages of this utility model can be further improved as follows:

[0010] The chuck includes a disc body and a connecting post. The disc body is fixedly mounted on the top of the upper steam cover. The connecting post is vertically mounted on the upper surface of the disc body. The flexible hose is sleeved on the outside of the connecting post. The outer wall of the connecting post is provided with an annular groove. The flexible hose is fixed in the annular groove by a clamp.

[0011] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the design of the chuck body and connecting post structure provides a stable connection foundation for the flexible hose; the annular groove on the outer wall of the connecting post, together with the clamp, can firmly fix the flexible hose, prevent alcohol vapor from leaking at the connection point, further improve the sealing performance, and at the same time ensure that the flexible hose will not fall off during frequent operation, thereby improving the reliability of the device.

[0012] Furthermore, the steamer lid locking device includes a fixed base, a locking body, and a locking member; the fixed base is fixedly disposed on the top edge of the steamer, one end of the locking body is hinged to the fixed base, and the other end is provided with a slot; a locking block that cooperates with the slot is provided at a corresponding position on the edge of the upper steamer lid, and the locking member passes through the locking body to fasten the locking block in the slot.

[0013] The beneficial effects of adopting the above-mentioned improved solution are as follows: the cooperative design of the fixing seat, locking body and locking parts of the steamer lid locking device can reliably fix the upper steaming lid on the steamer. The fixing and disassembly operations are simple and convenient. Compared with the traditional connection method, the installation and disassembly of the upper steaming lid can be realized quickly, improving work efficiency. At the same time, it can effectively prevent the steamer lid from loosening and leaking air due to factors such as steam pressure during the distillation process.

[0014] Furthermore, the steamer is composed of multiple layers of steamer bodies stacked one on top of the other, with adjacent layers connected by a flange structure. Each layer of steamer body has a slurry inlet on its side wall. The flange structure of the steamer body includes an upper flange and a lower flange. The upper flange is located at the top of the steamer body, and the lower flange is located at the bottom of the steamer body. The upper flange and the lower flange are fixedly connected by a bolt and nut assembly and are provided with a sealing gasket.

[0015] It also includes a machine for loading the still, which includes a conveying track, a hopper, and a lifting mechanism. The conveying track is located on one side of the still, the hopper is slidably mounted on the conveying track, and the lifting mechanism is connected to the hopper to drive the hopper to rise and fall, conveying the mash into the still. The conveying track is inclined and lower at the end near the still. The bottom of the hopper is provided with a discharge port, and the discharge port is provided with an openable baffle.

[0016] The boiler uses a multi-layered stacked boiler body connected by a flange structure, which increases the internal space and improves the throughput of a single distillation compared to ordinary boiler bodies; the bolt and nut assembly and sealing gasket of the flange structure ensure the sealing and connection stability between adjacent boiler bodies.

[0017] Furthermore, the sealing part includes a sealing outer shell and a sealing inner shell. The sealing outer shell is sleeved on the outside of the sealing inner shell, and the sealing ring is disposed at the connection between the sealing inner shell and the flexible hose. A sealing cavity is formed between the sealing outer shell and the sealing inner shell, and the top of the sealing outer shell is provided with an injection port that communicates with the sealing cavity.

[0018] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the sealing outer shell and sealing inner shell structure of the sealing part, together with the sealing ring and sealing cavity, form multiple sealing protections, which further enhances the sealing performance of the device; the liquid injection port at the top of the sealing outer shell can inject sealing fluid into the sealing cavity, and the sealing fluid can be replenished or replaced according to the actual use, ensuring the durability of the sealing effect and preventing alcohol vapor leakage.

[0019] Furthermore, the cooling tank includes a tank body and a cooling pipe. The cooling pipe is coiled inside the tank body. The flexible hose is connected to the inlet end of the cooling pipe. The bottom of the tank body is provided with a wine outlet. The outlet end of the cooling pipe is provided with an exhaust pipe that extends out of the top of the tank body. A steam valve is provided at the joint between the cooling pipe and the flexible hose to regulate the amount of steam entering the cooling tank.

[0020] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the cooling pipes coiled inside the cooling tank can fully contact the cooling medium inside the tank, improving cooling efficiency and enabling the alcohol vapor to be quickly cooled into liquid; the steam valve is installed at the joint between the cooling pipe and the flexible hose, which, compared with the traditional method of installing the valve at the bottom, allows for more precise adjustment of the amount of steam entering the cooling tank according to the actual situation of uneven mash density and uneven steam, ensuring the stability of the distillation process and improving the quality and yield of the liquor.

[0021] Furthermore, the steam valve is a manually adjustable valve, including a valve body, a valve core, and an adjusting handle. The valve body is located at the joint between the cooling pipe and the flexible hose, the valve core is located inside the valve body, and the adjusting handle is connected to the valve core. The opening and closing degree of the valve core is controlled by rotating the adjusting handle.

[0022] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the design of the valve body, valve core and adjustment handle of the manual regulating valve is simple in structure and easy to operate. The operator can easily control the opening and closing degree of the valve core by turning the adjustment handle, thereby achieving precise adjustment of the steam volume; the steam valve is set at the joint of the cooling pipe and the flexible hose, which can quickly respond to changes in the steam volume and make timely adjustments to ensure the rationality of steam treatment in the cooling tank.

[0023] Furthermore, the inner wall of the pot is provided with a spiral guide plate, which is used to guide steam to form a vortex in the pot. The surface of the guide plate is provided with multiple protrusions to increase the contact area between the steam and the mash.

[0024] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the spiral guide plate on the inner wall of the boiler can guide the steam to form a vortex in the boiler, so that the steam and the mash can be fully contacted, thereby improving the distillation efficiency; the protrusions on the surface of the guide plate increase the contact area between the steam and the mash, promote the full distillation of components such as alcohol in the mash, thereby improving the quality and yield of the wine, and at the same time helping to achieve the goal of energy saving and consumption reduction.

[0025] Compared with the prior art, the beneficial effects of the flexible sealing steam conveying structure for the upper steaming lid of this utility model for distillation are as follows: The flexible hose used in this utility model has good flexibility, which can not only realize the up and down lifting action of the upper steaming lid, but also meet the left and right movement needs. It no longer relies on the water seal structure, thus eliminating the problem of steam leakage caused by water seal from the root, ensuring that the steam is transported in pure gaseous form in the pipeline, and avoiding the mixing of liquid water and affecting the distillation effect.

[0026] In terms of sealing performance, the combination of chuck and flexible hose replaces the traditional water seal structure, breaking through the movement limitations of the water seal structure and enabling the upper distillation lid to move up and down flexibly. At the same time, the chuck and flexible hose are connected by annular grooves and clamps, and the sealing part has multiple sealing protection designs, including a sealing outer shell, a sealing inner shell, a sealing ring and a sealing cavity, forming a tight sealing system. This effectively solves the problem of air leakage from the still lid, ensuring that the alcohol vapor will not leak during the distillation process, guaranteeing the sealing and stability of the distillation process, and thus improving the distillation efficiency and the quality of the alcohol.

[0027] In terms of ease of operation, the application of flexible hoses frees the upper steaming lid from the limitations imposed by the water seal structure, allowing it to not only move up and down but also left and right, making operation more flexible and free. Simultaneously, the frequent water replenishment and cleaning required by the water seal structure are eliminated, greatly simplifying the operation process and further improving overall ease of operation and work efficiency. The design of the steaming lid locking device makes the installation and removal of the upper steaming lid simple and quick, significantly shortening operation time and improving work efficiency compared to traditional connection methods. The application of the machine-assisted steaming device changes the traditional manual steaming method. Using machine steaming with manual assistance not only saves significant labor costs but also improves the efficiency and uniformity of steaming.

[0028] In terms of production efficiency and cost control, the still employs a four-layer stacked structure connected by flanges, increasing internal space, improving the throughput per distillation cycle, and reducing the number of distillation batches, thereby enhancing overall production efficiency. Simultaneously, the addition ports on the side walls of each still facilitate flexible liquid addition according to different distillation process requirements, allowing for better control of the distillation process and improving production flexibility and adaptability. Furthermore, by optimizing the placement of the steam valves at the joint between the cooling pipe and the flexible hose, the amount of steam entering the cooling tank can be adjusted more precisely based on the uneven density of the mash and the unevenness of the steam, ensuring a stable distillation process and preventing product loss and reduced production efficiency due to improper steam control. This contributes to achieving energy conservation and emission reduction goals, and lowering production costs. Attached Figure Description

[0035] like Figs. 1-2 The diagram shows a first embodiment of a flexible sealing steam conveying structure for a top steaming lid used in distillation, provided by this utility model. In this embodiment, it includes a still 50, a top steaming lid 10, a chuck 60, a flexible hose 20, a sealing part 30, a cooling tank, and a lid locking device 40. The top steaming lid 10 is placed on top of the still 50, and the chuck 60 is placed on top of the top steaming lid 10. One end of the flexible hose 20 is connected to the chuck 60, and the other end is connected to the sealing part 30. The sealing part 30 is connected to the cooling tank. A sealing ring is provided inside the sealing part 30. The lid locking device 40 is located at the connection between the still 50 and the top steaming lid 10, and is used to tightly fix the top steaming lid 10 to the still 50.

[0036] First, place the upper steaming lid on top of the pot and fix it to the pot using the lid locking device. During the distillation process, if it is necessary to adjust the position of the upper steaming lid, the flexible hose can be used to lift and lower the lid. The alcohol vapor is then transported to the cooling tank through the chuck, flexible hose, and sealing part.

[0037] In the above technical solution, the chuck 60 includes a disc body and a connecting post. The disc body is fixedly installed on the top of the upper steam cover 10, and the connecting post is vertically installed on the upper surface of the disc body. The flexible hose 20 is sleeved on the outside of the connecting post, and the outer wall of the connecting post is provided with an annular groove. The flexible hose 20 is fixed in the annular groove by a clamp.

[0038] When installing the flexible hose, put it on the outside of the connecting column so that the hose corresponds to the annular groove. Then use a clamp to fasten it to the annular groove to complete the connection between the flexible hose and the chuck. During the operation of the device, the flexible hose can move with the upper steam cover to stably deliver alcohol vapor.

[0039] Furthermore, in the above technical solution, the steamer lid locking device 40 includes a fixed base, a locking body, and a locking member; the fixed base is fixedly set on the top edge of the steamer 50, one end of the locking body is hinged to the fixed base, and the other end is provided with a slot; the upper steam cover 10 is provided with a corresponding position on the edge of the slot and a locking block that cooperates with the slot; the locking member passes through the locking body and is used to fasten the locking block in the slot.

[0040] When installing the steaming lid, align the slot at one end of the locking body with the locking block on the edge of the steaming lid, so that the locking block is inserted into the slot, and then fasten the locking block by passing the locking piece through the locking body; when disassembling, loosen the locking piece, open the locking body, and the steaming lid can be removed.

[0041] Furthermore, in the above technical solution, the boiler 50 is composed of multiple layers of boiler bodies stacked one on top of the other, with adjacent layers of boiler bodies connected by a flange structure. Each layer of boiler body has a slurry inlet on its side wall. The flange structure of the boiler body includes an upper flange and a lower flange. The upper flange is located at the top of the boiler body, and the lower flange is located at the bottom of the boiler body. The upper flange and the lower flange are fixedly connected by a bolt and nut assembly and are provided with a sealing gasket.

[0042] When assembling the still, align the upper flange of the lower still with the lower flange of the upper still, place the sealing gasket, and fix the connection with bolts and nuts. Before distillation, add an appropriate amount of liquid into the still through the filling port according to the process requirements, and then carry out the distillation operation after loading the mash.

[0043] Furthermore, in the above technical solution, the sealing part 30 includes a sealing outer shell and a sealing inner shell. The sealing outer shell is sleeved on the outside of the sealing inner shell, and the sealing ring is disposed at the connection between the sealing inner shell and the flexible hose 20. A sealing cavity is formed between the sealing outer shell and the sealing inner shell, and the top of the sealing outer shell is provided with an injection port that communicates with the sealing cavity.

[0044] When installing the sealing part, install the sealing ring at the connection between the inner sealing shell and the flexible hose, and assemble the outer sealing shell and the inner sealing shell. Before use, inject an appropriate amount of sealing liquid into the sealing cavity through the injection port. If the sealing effect is found to decrease during the distillation process, the sealing liquid can be replenished or replaced through the injection port.

[0045] Furthermore, in the above technical solution, the cooling tank includes a tank body and a cooling pipe. The cooling pipe is coiled inside the tank body, and the flexible hose 20 is connected to the inlet end of the cooling pipe. The bottom of the tank body is provided with an outlet, and the outlet end of the cooling pipe is provided with an exhaust pipe that extends out of the top of the tank body. A steam valve is provided at the joint between the cooling pipe and the flexible hose 20 to regulate the amount of steam entering the cooling tank.

[0046] The vapor enters the cooling pipe through a flexible hose. Under the action of the cooling medium in the cooling tank, the vapor is cooled into liquid in the cooling pipe and flows out from the outlet at the bottom of the tank. During the distillation process, the steam is observed and the amount of steam entering the cooling tank is controlled by adjusting the steam valve to ensure the smooth progress of the distillation and cooling process.

[0047] Furthermore, in the above technical solution, the steam valve is a manually adjustable valve, including a valve body, a valve core, and an adjusting handle. The valve body is located at the joint between the cooling pipe and the flexible hose 20, the valve core is located inside the valve body, and the adjusting handle is connected to the valve core. The opening and closing degree of the valve core is controlled by rotating the adjusting handle.

[0048] Furthermore, in the above technical solution, the inner wall of the boiler 50 is provided with a spiral guide plate. The guide plate is used to guide the steam to form a vortex in the boiler 50. The surface of the guide plate is provided with multiple protrusions to increase the contact area between the steam and the mash.

[0049] During the distillation process, the generated steam forms a vortex in the still under the guidance of the spiral guide plate. It rises spirally along the guide plate, and the steam comes into full contact with the mash. When it passes through the protrusions on the surface of the guide plate, the contact area is further increased, and the distillation process is completed. The generated alcohol vapor is transported to the cooling tank through the flexible sealing steam conveying structure of the upper steam cover.

[0050] Specifically, the principle of this utility model is as follows:

[0051] The technical principle of this utility model is based on in-depth analysis and innovative improvements to various key aspects of the distillation process. Regarding the sealed vapor delivery structure, the combination of a chuck and a flexible hose replaces the traditional water seal structure. The chuck's disc and connecting post provide a stable installation base for the flexible hose. The design of the annular groove and clamp ensures a firm connection between the flexible hose and the chuck, guaranteeing connection stability while utilizing the flexibility of the hose to allow for flexible movement of the upper distillation lid. The sealing outer shell and inner shell of the sealing part, together with the sealing ring and sealing cavity, form multiple layers of sealing protection. The injection port at the top of the sealing outer shell allows for the injection of sealing liquid, further enhancing the sealing effect and effectively preventing vapor leakage, ensuring that the vapor can be smoothly delivered to the cooling tank through the flexible hose.

[0052] The steamer lid locking device achieves a reliable connection between the upper steaming lid and the steamer through the cooperation of the fixing base, the locking body, and the locking element. During installation, align the slot at one end of the locking body with the locking block on the edge of the upper steaming lid, so that the locking block is inserted into the slot. Then, the locking element passes through the locking body to secure the locking block. Disassembly is performed by reversing the operation. This structural design is simple and practical, and can effectively ensure the sealing and stability of the upper steaming lid during the distillation process.

[0053] The still employs a multi-layered stacked structure connected by flanges, with adjacent stills secured using bolt and nut assemblies and sealing gaskets to ensure a tight and stable connection. This multi-layered structure also increases the internal space of the still, allowing for the loading of more mash and increasing the throughput per distillation cycle. Each still's side wall features a slurry inlet, facilitating the addition of liquids during distillation according to process requirements, enabling flexible control of the distillation process.

[0054] The conveying track of the machine's steaming device is inclined, and the hopper can slide along the track under the action of gravity. The lifting mechanism is used to adjust the height of the hopper, and the openable baffle at the bottom of the hopper can control the conveying volume and speed of the mash. Through this design, the automated conveying of mash is achieved, which greatly improves the efficiency and uniformity of steaming compared with the traditional manual steaming method, and reduces labor costs.

[0055] In terms of steam regulation and cooling, the steam valve is located at the joint between the cooling pipe and the flexible hose. Compared to the traditional method of setting the valve at the bottom of the cooling tank, this allows for faster and more precise adjustment of the amount of steam entering the cooling tank based on the actual condition of the mash. When the mash density is uneven or the steam generation is uneven, the operator can control the opening and closing of the valve core by turning the adjustment handle of the manual regulating valve, thereby adjusting the steam flow and ensuring a stable distillation process. The cooling pipes coiled inside the cooling tank can fully contact the cooling medium inside the tank, using the principle of heat exchange to quickly cool the vapor into liquid, which flows out from the outlet at the bottom of the tank.
