A steam column for rapidly and uniformly heating camellia seed

Abstract

This utility model relates to the field of camellia seed processing, specifically a steaming tower for rapidly and uniformly heating camellia seeds. It includes a tower pot, a tower body fixedly connected to the top of the pot, a fixed frame and a filter screen fixedly connected to the inner cavity of the tower body, and a stirring mechanism and an auxiliary mechanism within the inner cavity. In this utility model, the operation of a servo motor drives a rotating rod to rotate, simultaneously driving a stirring plate and a connecting block to rotate. The rotation of the stirring plate stirs the camellia seeds. When the connecting block rotates, a first wedge intermittently pushes a second wedge, allowing the second wedge to move continuously up and down using the push from the first wedge and its own weight, thus vibrating and turning the camellia seeds.

Description

Technical Field

[0001] This utility model relates to the field of camellia seed processing, specifically a steaming tower for rapidly and uniformly heating camellia seeds. Background Technology

[0002] Camellia seeds, also known as oil tea seeds, are the fruit of the oil tea tree. When processing camellia seeds, a steaming tower is often used. The camellia seed steaming tower is a key piece of equipment in the processing of camellia seeds. It is mainly used to steam the camellia seeds. Through the action of heating and steam, the camellia seeds are heated evenly to achieve the purposes of softening, blanching, and dehumidifying.

[0003] In existing technologies, camellia seeds are often processed using a camellia seed steaming tower. A typical camellia seed steaming tower usually delivers steam into the tower to process the camellia seeds. In some cases, to increase the uniformity of heating during processing, a stirring device is installed inside the tower. However, relying solely on the stirring device to stir and heat the camellia seeds in the tower can still lead to uneven heating due to the stacking and accumulation of the camellia seeds within the tower. This reduces the efficiency and effectiveness of the camellia seed processing and heating. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, relying solely on stirring equipment to stir and heat the camellia seeds in the tower can stir the seeds, but the seeds are prone to uneven heating due to their stacking and accumulation. This reduces the efficiency and effectiveness of processing and heating the camellia seeds. This invention proposes a steaming tower for rapidly and evenly heating camellia seeds.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a steaming tower for rapidly and uniformly heating camellia seeds, including a tower pot, a tower body fixedly connected to the top of the tower pot, a fixing frame and a filter screen fixedly connected to the inner cavity of the tower body, and a stirring mechanism and an auxiliary mechanism provided in the inner cavity of the tower body;

[0006] The stirring mechanism includes a servo motor, one side of which is fixedly connected to the top of the fixed frame. The output end of the servo motor passes through the fixed frame and is fixedly connected to a rotating rod. A rotating block is fixedly connected to the surface of the rotating rod, and a stirring plate is fixedly connected to the bottom of the rotating block.

[0007] Preferably, the auxiliary mechanism includes a sliding ring block, the surface of which is slidably connected to the inner cavity of the tower body, a connecting plate fixedly connected to the bottom of the sliding ring block, a vibration block fixedly connected to one side of the connecting plate, and multiple vibration blocks. A limit block is fixedly connected to the inner cavity of the tower body, one side of which is slidably connected to one side of the connecting plate. A connecting block is fixedly connected to the surface of the rotating rod, a first wedge block is fixedly connected to the top of the connecting block, a second wedge block is fixedly connected to one side of the sliding ring block, and an elastic component is provided on the top of the sliding ring block.

[0008] Preferably, the elastic component includes a spring, one end of which is fixedly connected to the top of the sliding ring block, and a fixing ring block is fixedly connected to the inner cavity of the tower body, the bottom of which is fixedly connected to one end of the spring.

[0009] Preferably, a limiting rod is fixedly connected to the top of the sliding ring block, one end of the limiting rod passes through the fixed ring block, and the surface of the spring is sleeved on the surface of the limiting rod.

[0010] Preferably, an air outlet pipe is fixedly connected to the inner cavity of the tower body, an electronic pressure relief valve is fixedly connected to the surface of the air outlet pipe, and a PLC controller is fixedly connected to the surface of the tower body.

[0011] Preferably, an annular storage box is fixedly connected to the surface of the tower body, and the surface of the gas outlet pipe is fixedly connected to the inner cavity of the annular storage box.

[0012] Preferably, the inner cavity of the annular storage box is fixedly connected to an exhaust pipe and a drain pipe, and a valve body is fixedly connected to the surface of the drain pipe.

[0013] Preferably, the inner cavity of the tower body is fixedly connected to a discharge pipe, a blocking plate is provided on one side of the discharge pipe, and a reinforcing block is fixedly connected to the inner cavity of the tower body, with the top of the reinforcing block fixedly connected to the bottom of the filter screen.

[0014] The advantages of this utility model are:

[0015] This invention utilizes a servo motor to drive a rotating rod, which in turn rotates the stirring plate and connecting block. The rotation of the stirring plate stirs the camellia seeds. As the connecting block rotates, the first wedge intermittently pushes the second wedge, allowing the second wedge to move continuously up and down using the push from the first wedge and its own weight. This vibration and stirring of the camellia seeds improves the efficiency and uniformity of heating. The invention not only increases the uniformity of heating the camellia seeds but also improves the efficiency of heating. Furthermore, it provides a heat exchange effect for the exhaust steam. This solves the problem that relying solely on stirring equipment to heat the camellia seeds in the tower, while effective, can result in uneven heating due to the stacking and accumulation of seeds, thus reducing the efficiency and effectiveness of camellia seed processing and heating.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] This application discloses a steaming tower for rapidly and uniformly heating camellia seeds. (Refer to...) Figure 1 and Figure 3 A steaming tower for rapidly and uniformly heating camellia seeds includes a tower pot 1, a tower body 2 fixedly connected to the top of the tower pot 1, a fixing frame 3 and a filter screen 6 fixedly connected to the inner cavity of the tower body 2, and a stirring mechanism 4 and an auxiliary mechanism 5 provided in the inner cavity of the tower body 2.

[0027] The stirring mechanism 4 includes a servo motor 401. One side of the servo motor 401 is fixedly connected to the top of the fixed frame 3. The output end of the servo motor 401 passes through the fixed frame 3 and is fixedly connected to a rotating rod 402. A rotating block 403 is fixedly connected to the surface of the rotating rod 402. A stirring plate 404 is fixedly connected to the bottom of the rotating block 403.

[0028] The pressure vessel 1 can be connected to the tower body 2. The pressure vessel 1 generates steam upon heating, which rises into the interior of the tower body 2 to heat the camellia seeds. Part of the steam condenses and flows back to the pressure vessel 1 for reheating. The pressure vessel 1 and tower body 2 are existing technologies in this field, and therefore will not be described in detail here. The tower body 2 also allows for the fixing and installation of the filter screen 6 and the mounting bracket 3. The filter screen 6 has a pore size of less than two millimeters. Typically, camellia seeds have a diameter of 10 to 15 millimeters, thus the filter screen 6 allows the steam from the pressure vessel 1 to effectively heat the camellia seeds during use. The heat is absorbed, and the camellia seeds are less likely to fall through the filter screen 6 into the interior of the tower 1. The filter screen 6 can be of different models, such as the VTON series. The fixing frame 3 can be connected to the rotating rod 402 via the servo motor 401. When the servo motor 401 is in operation, it can smoothly drive the rotating rod 402 and the rotating block 403 installed on the surface of the rotating rod 402 to rotate. When the rotating block 403 rotates, it can drive the stirring plate 404 to rotate synchronously, thereby realizing the stirring of the camellia seeds inside the tower 2, so that they can be heated more evenly.

[0029] Reference Figure 3 and Figure 5The auxiliary mechanism 5 includes a sliding ring block 501, the surface of which is slidably connected to the inner cavity of the tower body 2. A connecting plate 502 is fixedly connected to the bottom of the sliding ring block 501, and a vibrating block 504 is fixedly connected to one side of the connecting plate 502. Multiple vibrating blocks 504 are provided. A limiting block 503 is fixedly connected to the inner cavity of the tower body 2, and one side of the limiting block 503 is slidably connected to one side of the connecting plate 502. A connecting block 505 is fixedly connected to the surface of the rotating rod 402, and a first wedge block 506 is fixedly connected to the top of the connecting block 505. A second wedge block 508 is fixedly connected to one side of the sliding ring block 501. An elastic component 507 is provided on the top of the sliding ring block 501. The tower body 2 can be connected to the connecting plate 502 through the sliding ring block 501, and the limiting block 503 can limit the vertical movement of the connecting plate 502, making it sufficiently stable during vertical movement. The vibrating block installed on one side of the connecting plate 502... Vibrating block 504 can move up and down together with connecting plate 502, thereby vibrating the camellia seeds through continuous up and down movement, and turning the camellia seeds so that the camellia seeds can be heated more evenly. Rotating rod 402 can be connected to first wedge block 506 through connecting block 505. When first wedge block 506 rotates with rotating rod 402, it can push second wedge block 508. After being pushed, second wedge block 508 can drive sliding ring block 501 to move upward together, thereby moving connecting plate 502 and vibrating block 504 upward. When first wedge block 506 continues to rotate, it will stop pushing second wedge block 508. At this time, connecting plate 502 and vibrating block 504 can fall by gravity. The continuous rotation of second wedge block 508 can effectively realize the continuous up and down movement of vibrating block 504, and realize the vibration and turning of camellia seeds by vibrating block 504.

[0030] Reference Figure 4 and Figure 5 The elastic component 507 includes a spring 5071, one end of which is fixedly connected to the top of the sliding ring block 501. A fixed ring block 5072 is fixedly connected to the inner cavity of the tower body 2. The bottom of the fixed ring block 5072 is fixedly connected to one end of the spring 5071. The tower body 2 can connect the spring 5071 through the fixed ring block 5072. When the sliding ring block 501 moves upward due to the pushing of the first wedge block 506, the sliding ring block 501 will squeeze the spring 5071. When the sliding ring block 501 is no longer pushed by the first wedge block 506, the spring 5071 can use its own elasticity to apply a downward elastic pushing force to the sliding ring block 501, the connecting plate 502 and the vibrating block 504, thereby increasing the speed of the vibrating block 504 when it moves downward, thereby increasing the vibration effect on the camellia seeds by increasing its downward speed.

[0031] Reference Figure 5 and Figure 6A limiting rod 17 is fixedly connected to the top of the sliding ring block 501. One end of the limiting rod 17 passes through the fixed ring block 5072. The surface of the spring 5071 is sleeved on the surface of the limiting rod 17. The limiting rod 17 can limit the extension and retraction of the spring 5071 and the movement of the sliding ring block 501. It can not only limit the extension and retraction of the spring 5071, making it less likely to deform during extension and retraction, but also increase the stability of the sliding ring block 501 when it moves up and down by utilizing the connection between the limiting rod 17 and the fixed ring block 5072, making it less likely to deviate or shake during up and down movement.

[0032] Reference Figure 2 and Figure 4 A vent pipe 7 is fixedly connected to the inner cavity of the tower body 2. An electronic pressure relief valve 8 is fixedly connected to the surface of the vent pipe 7. A PLC controller 9 is fixedly connected to the surface of the tower body 2. The vent pipe 7 allows steam to be discharged from inside the tower body 2, while the electronic pressure relief valve 8 detects the pressure inside the tower body 2 through the vent pipe 7 and automatically releases the pressure when a certain pressure is reached. The PLC controller 9 is electrically connected to the electronic pressure relief valve 8, enabling the PLC controller 9 to control the electronic pressure relief valve 8. Automatic pressure relief is achieved, and both the PLC controller 9 and the electronic pressure relief valve 8 can be different models. For example, the PLC controller 9 can be a Siemens S7-1200, and the electronic pressure relief valve 8 can be a 10-RV. The electronic pressure relief valve 8 receives an electrical signal from the PLC controller 9 and quickly opens to release steam when the pressure exceeds the safety threshold. It automatically closes after the pressure drops back to the normal range, thereby achieving automated pressure relief protection. The electronic pressure relief valve 8 and the PLC controller 9 are existing technologies in this field, so they will not be described in detail here.

[0033] Reference Figure 4 An annular storage tank 10 is fixedly connected to the surface of the tower body 2. The surface of the vent pipe 7 is fixedly connected to the inner cavity of the annular storage tank 10. An exhaust pipe 11 and a drain pipe 12 are fixedly connected to the inner cavity of the annular storage tank 10. A valve body 13 is fixedly connected to the surface of the drain pipe 12. The annular storage tank 10 stores water. The steam discharged by the vent pipe 7 will enter the interior of the annular storage tank 10 and heat the water inside the annular storage tank 10. This allows the annular storage tank 10 to exchange heat with the water inside while also providing some insulation for the tower body 2. At the same time, the exhaust pipe 11 prevents the internal pressure of the annular storage tank 10 from becoming too high. The drain pipe 12 facilitates the removal of water from the annular storage tank 10. The valve body 13 controls the opening and closing of the drain pipe 12, preventing water from flowing out of the annular storage tank 10 through the drain pipe 12 when it is not needed.

[0034] Reference Figure 2 and Figure 3 The inner cavity of the tower body 2 is fixedly connected to a discharge pipe 14, and a blocking plate 15 is provided on one side of the discharge pipe 14. A reinforcing block 16 is fixedly connected to the inner cavity of the tower body 2. The top of the reinforcing block 16 is fixedly connected to the bottom of the filter screen 6. The discharge pipe 14 allows workers to easily remove camellia seeds from the inside of the tower body 2, while the blocking plate 15 can close the discharge pipe 14 to a certain extent, so that when the camellia seeds do not need to be removed from the inside of the tower body 2, they are not easy to flow out of the inside of the tower body 2 through the discharge pipe 14. The reinforcing block 16 can reinforce the use of the filter screen 6, making it more stable during use.

[0035] Working Principle: When using this device, the operator adds the camellia seeds to be processed and heated into the tower body 2. Then, the tower kettle 1 is operated to allow the steam generated in the kettle to pass smoothly through the filter screen 6 into the tower body 2, heating the camellia seeds. Afterward, the operator starts the servo motor 401. During operation, the servo motor 401 drives the rotating block 403 and connecting block 505 to rotate via the rotating rod 402. The rotating block 403, in turn, drives the stirring plate 404 to rotate, thus stirring the camellia seeds and ensuring more even heating. The rotation of the connecting block 505 drives the first wedge block 506 to rotate as well. After rotating to a certain angle, the first wedge block 506 pushes against the second wedge block 508, causing the sliding ring block 501, connecting plate 502, and multiple vibrating blocks 504 to move upwards synchronously. After rotating to a certain angle, the first wedge block 506 will release its pressure on the second wedge block. When pushed by 508, the second wedge block 508 and the sliding ring block 501 can move downward by their own weight and the elasticity of the spring 5071, and drive multiple vibrating blocks 504 to move downward together. The first wedge block 506 can continuously rotate, so that multiple vibrating blocks 504 can move up and down repeatedly, thereby realizing the vibration and turning of the camellia seeds, further improving the efficiency of the camellia seeds when heated. At the same time, the electronic pressure relief valve 8 can detect the pressure inside the tower body 2. When the pressure is high, the electronic pressure relief valve 8 can automatically open, and discharge part of the pressure inside the tower body 2 into the interior of the annular storage tank 10 through the air outlet pipe 7. When the water inside the annular storage tank 10 combines with the steam, it will realize the heat exchange of the steam. The air after heat exchange will be discharged through the exhaust pipe 11. The water inside the annular storage tank 10 can not only realize heat exchange, but also realize the heat preservation of the tower body 2, thereby further improving the efficiency of heating the camellia seeds.
