Description

Technical Field

[0001] This utility model relates to the field of camellia seed cleaning machines, specifically a high-pressure gas cleaning machine for camellia seeds. Background Technology

[0002] Camellia seeds, as an oilseed crop, often have impurities such as dust, debris, and shell residue adhering to their surface. These impurities can affect the product quality in subsequent pressing and refining processes. Therefore, cleaning is a crucial step before camellia seed processing. High-pressure gas cleaners are widely used in camellia seed cleaning due to their advantages such as no water pollution, low energy consumption, and no damage to the camellia seed surface.

[0003] However, most of the jet heads in existing high-pressure gas cleaners are fixedly installed. They remove impurities by spraying high-pressure gas into the drum screen. However, during long-term use, the limited spray range of the fixed jet head cannot fully cover the camellia seeds inside the drum screen. As a result, some areas of camellia seeds are difficult to reach with high-pressure gas, leading to uneven cleaning and impurity residue. At the same time, the fixed jet head cannot adapt to the rotation rhythm of the drum screen. The contact time and contact angle between the high-pressure gas and the camellia seeds are fixed, resulting in poor impurity removal and low cleaning efficiency. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a high-pressure gas cleaner for camellia seeds, so as to solve the technical problems of uneven cleaning of camellia seeds, residual impurities, poor impurity removal effect, and low cleaning efficiency caused by the fixed jet head in the existing high-pressure gas cleaner.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-pressure gas cleaner for camellia seeds, comprising a cleaner, the cleaner comprising a base frame and a mounting frame, the front and rear ends of the mounting frame being fixedly connected to a jetting mechanism by clamps, the jetting mechanism comprising two connecting air pipes, a rotating air pipe being rotatably connected between the two connecting air pipes, a driven gear being provided on the edge of the rotating air pipe, a motor being provided on the top of the connecting air pipe near the rotating air pipe by a fixing rod, a driving gear being provided on the output end of the motor, and the driving gear meshing with the driven gear; The bottom of the rotating air pipe is provided with multiple air jets, and the top of the rotating air pipe is provided with multiple connecting rods, with arc-shaped brushes provided on the top of the multiple connecting rods.

[0006] By adopting the above technical solution, the base frame and mounting structure of the cleaning machine form a stable support foundation, and the clamps firmly fix the jet mechanism. The rotating air pipes connecting the air pipes, in conjunction with gear transmission, enable the jet head to rotate and expand the coverage area; the arc-shaped brushes connected by the connecting rod move synchronously, taking into account both jet cleaning and screen cleaning, overcoming the limitations of the fixed structure, and improving the comprehensiveness and effectiveness of cleaning.

[0007] Furthermore, the plurality of jet heads are evenly spaced along the length of the rotating air pipe, and the jet direction of the jet heads is towards the inner side of the drum screen of the cleaning machine; the curvature of the arc-shaped brush is adapted to the outer curvature of the drum screen, and the bristles of the arc-shaped brush are in elastic contact with the screen surface of the drum screen.

[0008] By adopting the above technical solution, the jet nozzles are distributed along the rotating air pipe and face the inside of the drum screen, so that they can fully cover the camellia seeds inside the screen when rotating. The arc-shaped brush is adapted to the curvature of the drum screen, making elastic contact with the screen mesh, and cleaning impurities in real time during rotation to avoid clogging. The combination of the two makes the air jet cleaning more uniform, while ensuring the screen mesh is unobstructed, improving cleaning efficiency and continuity.

[0009] Furthermore, a slag receiving hopper is provided on the top of the base frame, and a drum screen is mounted on the top of the slag receiving hopper via a mounting frame. A drive assembly for driving the drum screen to rotate is provided at the front end of the base frame.

[0010] By adopting the above technical solution, the slag receiving hopper at the top of the base frame can centrally collect impurities, avoiding scattering and contamination. The mounting frame securely installs the drum screen above the slag receiving hopper, allowing impurities to fall directly into the hopper; the drive component at the front end of the base frame drives the drum screen to rotate, causing the camellia seeds to tumble, ensuring thorough cleaning and improving the orderliness of the operation.

[0011] Furthermore, one end of the drum screen is provided with a feed inlet, and the other end of the drum screen is provided with a discharge outlet.

[0012] By adopting the above technical solution, the drum screen is equipped with a feed inlet and a discharge outlet at both ends, realizing material separation. The feed inlet facilitates precise feeding and avoids scattering; the discharge outlet facilitates the smooth discharge of materials after cleaning, forming a smooth "feeding-cleaning-discharging" process, reducing accumulation and improving operating efficiency.

[0013] Furthermore, a sealing structure is provided at the rotating connection between the connecting air pipe and the rotating air pipe. The sealing structure fits into the connection surface of the two to prevent high-pressure gas leakage.

[0014] By adopting the above technical solution, a sealing structure is installed at the rotating connection between the connecting air pipe and the rotating air pipe to prevent high-pressure gas leakage by fitting the connection surface. This ensures stable jet pressure and sufficient cleaning power from the jet head; at the same time, it avoids gas waste and leakage risks, improving equipment reliability and cleaning effect.

[0015] Furthermore, the two ends of the connecting rod are respectively fixedly connected to the rotating air pipe and the arc-shaped brush. The bristles of the arc-shaped brush are made of flexible and wear-resistant material, which is suitable for the cleaning scenario of the drum screen.

[0016] By adopting the above technical solution, the connecting rod has a fixed rotating air pipe and an arc-shaped brush at both ends, ensuring that the two rotate synchronously. The arc-shaped brush is made of flexible and wear-resistant material, which is suitable for the cleaning of drum screens. It ensures the cleaning effect of the screen without damaging it, and its wear-resistant properties extend its service life and improve the durability of the equipment.

[0017] Furthermore, the drive assembly is connected to the end of the drum screen via a transmission, and the power output direction of the drive assembly is consistent with the rotation direction of the drum screen, ensuring the smooth operation of the drum screen.

[0018] By adopting the above technical solution, the drive component is connected to the end of the drum screen, and the power output direction matches the rotation direction of the screen body. This ensures precise and efficient power transmission, reduces losses and jamming, guarantees stable operation of the drum screen, and ensures even agitation of the camellia seeds, thus guaranteeing cleaning uniformity and equipment stability.

[0019] Furthermore, the mounting frame is fixedly connected to the base frame, and the support structure of the mounting frame is adapted to the shape of the drum screen, providing stable support for the drum screen.

[0020] By adopting the above technical solution, the mounting frame is fixedly connected to the base frame, providing stable support. Its support structure is adapted to the shape of the drum screen, ensuring a close fit to the screen body, uniform stress distribution, avoiding localized overload damage, guaranteeing long-term stable operation of the drum screen, and improving the overall reliability of the equipment.

[0021] In summary, the present invention has the following main advantages: 1. This utility model sets up a rotatable jet mechanism, in which the motor meshes with the driven gear on the rotating air pipe through the driving gear, driving the rotating air pipe to drive multiple jet heads to rotate synchronously. The jet heads are distributed along the length of the rotating air pipe and jet towards the inside of the drum screen, which greatly expands the coverage of high-pressure gas. At the same time, the jet angle and contact time are dynamically adjusted, which solves the technical problems of uneven cleaning, impurity residue, poor impurity removal effect and low cleaning efficiency of existing fixed jet heads. 2. This utility model features an arc-shaped brush adapted to the drum screen. The brush is fixedly connected to the rotating air pipe via a connecting rod and rotates synchronously with the air pipe. The brush bristles are made of a flexible and wear-resistant material and make elastic contact with the drum screen mesh. While the air is being sprayed for cleaning, the screen mesh is cleaned in real time, preventing impurities from accumulating and clogging the screen. This ensures the continuity of the cleaning process and further enhances the overall cleaning effect and operational stability in conjunction with the air spray mechanism.

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] A high-pressure gas cleaner for camellia seeds, such as Figure 1-4 As shown, the system includes a cleaning machine 1, which includes a base frame 101 and a mounting frame 103. The front and rear ends of the mounting frame 103 are fixedly connected to an air jet mechanism 2 by clamps. The air jet mechanism 2 includes two connecting air pipes 201, and a rotating air pipe 202 is rotatably connected between the two connecting air pipes 201. A driven gear 207 is provided on the edge of the rotating air pipe 202. A motor 205 is provided on the top of the connecting air pipe 201 near the rotating air pipe 202 by a fixing rod 204. A driving gear 206 is provided on the output end of the motor 205, and the driving gear 206 meshes with the driven gear 207. Multiple jet nozzles 203 are installed at the bottom of the rotating air pipe 202, and multiple connecting rods 208 are installed at the top of the rotating air pipe 202. Arc-shaped brushes 209 are installed at the top of the connecting rods 208. The mounting bracket 103 secures the jet mechanism 2 with clamps, ensuring that the jet mechanism 2 is firmly installed and stably positioned. Two connecting air pipes 201 support the rotation of the rotating air pipe 202. The motor 205 drives the rotating air pipe 202 to rotate via the drive gear 206 and the driven gear 207, causing the bottom jet nozzles 203 to rotate and expand the jet coverage area. The arc-shaped brushes 209 connected to the top connecting rods 208 rotate synchronously, enabling jet cleaning and brush cleaning to be carried out in tandem. This effectively solves the problem of incomplete cleaning of fixed structures, improving cleaning effect and operational continuity.

[0026] See Figure 1 , Figure 4Multiple jet nozzles 203 are evenly spaced along the length of the rotating air pipe 202, with the jet direction of the nozzles 203 facing the inner side of the drum screen 104 of the cleaning machine 1. The arc of the curved brush 209 matches the outer arc of the drum screen 104, and the bristles of the curved brush 209 make elastic contact with the screen surface of the drum screen 104. The multiple jet nozzles 203 are distributed along the length of the rotating air pipe 202 to ensure that the jets cover the entire length direction during rotation, and the jet direction is facing the inner side of the drum screen 104, so that the high-pressure gas can accurately act on the camellia seeds inside the screen, improving the cleaning targeting. The arc of the curved brush 209 matches the outer arc of the drum screen 104, and the bristles make elastic contact with the screen, which ensures the cleaning effect without damaging the screen. It cleans the screen impurities in real time as the rotating air pipe 202 rotates, avoiding clogging that affects screening and cleaning. The two work together to improve the uniformity of cleaning and the stability of operation.

[0027] See Figure 3 , Figure 4 The base frame 101 has a slag-receiving hopper 102 on top, and a drum screen 104 is mounted on top of the slag-receiving hopper 102 via a mounting frame 103. A drive assembly 105 for rotating the drum screen 104 is located at the front end of the base frame 101. The slag-receiving hopper 102 at the top of the base frame 101 can directly collect impurities screened from the drum screen 104, achieving centralized collection of impurities, preventing them from scattering and polluting the equipment or environment, and reducing the difficulty of subsequent cleaning. The drum screen 104 is mounted on top of the slag-receiving hopper 102 via the mounting frame 103, which provides precise support for the drum screen 104, ensuring stable positioning during operation. The drive assembly 105 at the front end of the base frame 101 specifically drives the drum screen 104 to rotate, continuously agitating the camellia seeds inside the screen, ensuring that each camellia seed comes into contact with the air jet, improving the comprehensiveness of cleaning. The overall structure ensures stable and orderly operation.

[0028] See Figure 1 , Figure 2 The drum screen 104 has an inlet 106 at one end and an outlet 107 at the other end. The inlet 106 provides a dedicated feeding channel for the camellia seeds to be cleaned, facilitating precise feeding by operators or conveying equipment and preventing material spillage that could lead to waste or contamination. The outlet 107 provides a discharge channel for the cleaned camellia seeds. The inlet 106 and outlet 107, located at opposite ends, work in conjunction with the rotation of the drum screen 104 to create a directional flow of material from inlet to outlet, preventing material accumulation inside the screen and improving the cleaning effect, thus significantly enhancing the smoothness and efficiency of the operation process.

[0029] See Figure 1 , Figure 4A sealing structure is provided at the rotating connection between the connecting air pipe 201 and the rotating air pipe 202. This sealing structure fits snugly against the connection surfaces of both, preventing high-pressure gas leakage. The tight fit of this sealing structure at the rotating connection effectively blocks high-pressure gas leakage from the rotation gap. High-pressure gas leakage would cause a drop in the jet pressure of the jet head 203, affecting the impurity removal effect. The sealing structure ensures stable jet pressure, guaranteeing sufficient cleaning power. Simultaneously, it avoids wasting high-pressure gas, reducing energy consumption, and prevents leaked gas from impacting equipment components or posing safety hazards to operators, significantly improving equipment reliability and cleaning stability.

[0030] See Figure 3 , Figure 4 The connecting rod 208 is fixedly connected at both ends to the rotating air pipe 202 and the arc-shaped brush 209, respectively. The bristles of the arc-shaped brush 209 are made of flexible and wear-resistant material, suitable for the cleaning of the drum screen 104. The rigid connection between the connecting rod 208 and the rotating air pipe 202 ensures that the arc-shaped brush 209 can rotate completely synchronously with the rotating air pipe 202, avoiding relative movement that could lead to untimely cleaning. The flexible material of the arc-shaped brush 209 allows it to adhere to the screen of the drum screen 104 to clean impurities without scratching the screen. The wear-resistant material can withstand long-term rotational friction, extending the service life of the brush. It perfectly meets the long-term cleaning needs of the drum screen 104, improving the overall durability and ease of maintenance of the equipment.

[0031] See Figure 1 , Figure 2 The drive assembly 105 is connected to the end of the drum screen 104 via a transmission connection. The power output direction of the drive assembly is consistent with the rotation direction of the drum screen, ensuring smooth operation of the drum screen. This direct transmission method allows the power of the drive assembly 105 to be directly transmitted to the screen body, reducing power loss during transmission and improving transmission efficiency. The power output direction of the drive assembly 105 is consistent with the rotation direction of the drum screen 104, ensuring accurate power transmission and avoiding transmission jamming, equipment vibration, or component wear due to directional deviation. Stable power transmission keeps the drum screen 104 running at a uniform speed and smoothly, allowing the camellia seeds inside to turn evenly. Each camellia seed can fully contact the high-pressure gas, ensuring uniform cleaning and improving the stability of equipment operation.

[0032] See Figure 3 , Figure 4The mounting frame 103 is fixedly connected to the base frame 101. The support structure of the mounting frame is adapted to the shape of the drum screen, providing stable support for the drum screen. This fixed connection ensures a solid foundation for the mounting frame 103, preventing it from swaying or shifting when bearing the weight of the drum screen 104 or during equipment operation vibrations. The fit between the support structure of the mounting frame 103 and the shape of the drum screen 104 ensures a close fit between the support surface and the screen body, allowing the weight of the drum screen 104 to be evenly distributed on the mounting frame 103, preventing excessive local stress that could lead to component deformation or damage. This stable support ensures the long-term stable operation of the drum screen 104, reduces equipment failures, and improves the overall reliability and service life of the equipment.

[0033] The implementation principle of this embodiment is as follows: First, the camellia seeds to be cleaned are put into the feed port 106 of the drum screen 104, and the drive component 105 is started. Since the drive component 105 is connected to the end of the drum screen 104 and the power output direction is consistent with the rotation direction of the drum screen 104, it can drive the drum screen 104 to operate smoothly, so that the camellia seeds are continuously turned inside the drum screen 104.

[0034] Simultaneously, the motor 205 and high-pressure air source of the jet mechanism 2 are activated. The motor 205 is fixed to the top of the connecting air pipe 201 by the fixing rod 204. The driving gear 206 at its output end meshes with the driven gear 207 on the edge of the rotating air pipe 202, driving the rotating air pipe 202 to rotate around the rotating connection between the two connecting air pipes 201. The high-pressure gas enters the rotating air pipe 202 through the connecting air pipe 201, and then is sprayed towards the inside of the drum screen 104 through multiple jet nozzles 203 at the bottom of the rotating air pipe 202. As the rotating air pipe 202 rotates, the jet coverage area is expanded, achieving a comprehensive cleaning of the turned tea seeds.

[0035] When the rotating air pipe 202 rotates, the arc-shaped brush 209 fixed at its top by the connecting rod 208 rotates synchronously. Because the arc of the arc-shaped brush 209 matches the outer arc of the drum screen 104, and the brush bristles make elastic contact with the screen surface, it can clean the impurities attached to the screen surface in real time and avoid screen blockage. The rotating connection between the air pipe 201 and the rotating air pipe 202 is equipped with a sealing structure to prevent high-pressure gas leakage.

[0036] Impurities generated during washing fall through the screen of the drum screen 104 into the slag receiving hopper 102 at the bottom. The washed camellia seeds are discharged from the discharge port 107 as the drum screen 104 rotates. Throughout the process, the mounting frame 103 is fixedly connected to the base frame 101 and the support structure is adapted to the drum screen 104, providing stable support for the operation of the equipment.
