Description

Technical Field

[0001] This utility model relates to the field of leaching and draining equipment technology, specifically a high-efficiency forced draining device for leached materials. Background Technology

[0002] Leachers are core industrial equipment that utilize the principle of "like dissolves like" to extract target substances (such as oils and active plant components) from solid raw materials. They are widely used in oil processing, traditional Chinese medicine extraction, and food additive production. The most common application is in the oil industry, where they are used to extract oil from soybeans, rapeseed, and other oilseeds. Leachers are generally classified as tank-type leachers, rotary leachers, annular leachers, box-chain leachers, and drag chain leachers. Rotary leachers are currently the most widely used type due to their stable continuous operation, high leaching efficiency, and low residual oil rate. Their workflow revolves around a rotary table driving the leaching grid in a cyclical manner. Pre-treated oils fall through a feed hopper, are controlled by a star-shaped discharge valve, and are evenly spread into the leaching grid by a scraper. They then enter the leaching zone and undergo reverse processing through multiple spray pipes. The leaching chamber moves to the draining zone, where the false bottom closes. Gravity or negative pressure forces the residual mixed oil through the filter screen and perforated plate into the oil collection hopper and then to the mixed oil evaporation system. Finally, it moves to the unloading zone, where the false bottom opens to allow the wet meal to fall into the meal discharge hopper. The meal is then conveyed to the descaling machine by a scraper conveyor. After unloading, the leaching chamber returns to its original position with the turntable, completing the cycle. The draining process is an essential part of the leaching unit. Its main function is to separate liquids (such as solvents and water) from the material, reducing the amount of liquid residue. Through draining, valuable liquids carried in the material (such as solvents in the leaching process) can be recovered, enabling resource reuse. On the other hand, it reduces the burden on subsequent processes (such as drying and transportation), avoids adverse effects of liquid residue on subsequent operations, and ensures a smooth and efficient production process.

[0003] However, existing technologies have the following problems in practical use; When existing draining equipment is in use, it generally uses compressed air to blow the fine powder stuck in the gaps to the oil collection hopper by blowing the false bottom and the lower surface of the filter screen. However, after long-term use, fine particles are still easy to clog the filter screen and the inside of the holes. After accumulation, they cause a certain degree of blockage, which reduces the draining efficiency. In addition, it requires the staff to manually remove them from the inside of the equipment for deep cleaning every once in a while. Utility Model Content

However, after long-term use, fine particles are still prone to clogging the filter screen and the inside of the holes, causing a certain degree of blockage after accumulation, which reduces the draining efficiency and requires the staff to manually remove the equipment from the inside for deep cleaning every once in a while.

[0007] Preferably, two baffles are fixedly connected to the outer surface of the guide column. The two baffles are symmetrically distributed, and the side of each baffle away from the guide column is fixedly connected to the inner wall of the oil collecting hopper. The outer surfaces of the two baffles and the guide column together with the inner wall of the oil collecting hopper form a discharge cavity. The lower end of the discharge cavity corresponds to and communicates with the discharge port at the upper end of the grid filter screen. A discharge pipe is detachably connected to the lower end of the oil collecting hopper, and one end of the discharge pipe communicates with the discharge cavity.

[0008] Preferably, a negative pressure pipe is detachably connected to the outer surface of the oil collecting hopper, the negative pressure pipe is connected to the interior of the oil collecting hopper, and a control valve is detachably connected to the upper end of the negative pressure pipe. An oil outlet pipe is provided on the side of the outer surface of the oil collecting hopper away from the negative pressure pipe.

[0013] (III) Beneficial Effects This utility model provides a highly efficient forced draining device for leached materials, which has the following beneficial effects: This highly efficient forced draining device for leached materials utilizes a combination of an ultrasonic vibrator, a grid filter, a false bottom, and a spherical spring. During operation, the ultrasonic vibrator generates high-frequency vibrations, which are transmitted to the grid filter, causing micro-vibrations at the filter pore edges. These micro-vibrations break up the agglomeration of fine meal powder, making it difficult for it to adhere to the filter pore surface. Simultaneously, the localized liquid disturbance created by the vibration washes nearly clogged fine particles back into the wet meal layer, continuously maintaining filter pore patency and significantly reducing downtime for cleaning, enabling continuous production. The spherical spring also transmits vibrations to the false bottom, causing it to generate synergistic micro-vibrations that promote rapid seepage of mixed oil from the material matrix, further enhancing the separation efficiency between the wet meal and the mixed oil. The synergistic vibration of the false bottom and the grid filter creates elastic fluctuations, further reducing the resistance of the mixed oil through the filter layer and significantly improving solid-liquid separation efficiency. Furthermore, the elastic characteristics of the spherical spring buffer the rigid impact during vibration, reducing fatigue wear on various components and extending equipment lifespan, thus enhancing both the draining effect and operational stability.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution: a high-efficiency forced draining device for leached materials, including an oil collecting hopper 2 detachably connected to the lower end of an extractor 1. A guide column 3 is fixedly connected to the inner bottom wall of the oil collecting hopper 2. The axis of the guide column 3 is collinear with the axis of the oil collecting hopper 2, and a guide groove is provided on the outer surface of the guide column 3. An ultrasonic vibrator 4 is detachably connected to the upper end of the guide column 3. A grid filter screen 5 is provided at the upper end of the ultrasonic vibrator 4, and the outer surface of the grid filter screen 5 is detachably connected to the inner wall of the oil collecting hopper 2. A spherical spring 6 is provided in the middle of the upper end of the grid filter screen 5. A false bottom 7 is detachably connected to the upper end of the spherical spring 6. Both the grid filter screen 5 and the false bottom 7 have discharge ports 11 at their upper ends, and the two discharge ports 11 are arranged vertically and vertically. The discharge port at the upper end of the false bottom 7... The inner wall of the 11 is rotatably connected to a movable plate 12. The outer surface of the guide column 3 is fixedly connected to two partitions 13. The two partitions 13 are symmetrically distributed, and the side of the two partitions 13 away from the guide column 3 is fixedly connected to the inner wall of the oil collecting hopper 2. The two partitions 13 and the outer surface of the guide column 3 together with the inner wall of the oil collecting hopper 2 form a discharge cavity. The lower end of the discharge cavity corresponds to and is connected to the discharge port 11 at the upper end of the grid filter screen 5. The lower end of the oil collecting hopper 2 is detachably connected to a discharge pipe 14, and one end of the discharge pipe 14 is connected to the discharge cavity. The upper end of the grid filter screen 5 is provided with multiple telescopic rods 8 at intervals along the circumference, and the upper ends of the multiple telescopic rods 8 are detachably connected to the lower end of the false bottom 7. The upper end of the false bottom 7 is provided with multiple irregular springs 9 at intervals along the circumference. Through the above technical solution, the axis of the guide column 3 is collinear with the axis of the oil collecting hopper 2, which can ensure the coaxiality of itself and the ultrasonic vibrator 4, grid filter screen 5 and other components connected above, avoiding uneven vibration transmission or unbalanced oil distribution due to eccentricity. The guide groove set on the outer surface of the guide column 3 can guide the oil leaking from the grid filter screen 5 to flow quickly along the groove to the bottom of the oil collecting hopper 2, preventing the oil from stagnating and accumulating in the hopper, and improving the oil collection efficiency. The false bottom 7 is the direct bearing surface of the leached material, ensuring that the material does not leak while allowing the separated oil to penetrate into the grid filter screen 5. The multiple telescopic rods 8 at the upper end of the grid filter screen 5 can support the false bottom 7 and also help transmit the vibration of the grid filter screen 5 itself. After the draining is completed, it is necessary to drain the oil. When discharging waste, the movable plate 12 is opened to allow the waste to enter the discharge port 11. The waste is then transported through the discharge port 11 to the interior of the discharge pipe 14 and to subsequent processes. The discharge ports 11 are respectively opened at corresponding positions on the grid filter 5 and the false bottom 7, and are arranged vertically to form a vertical material channel between the false bottom 7 and the grid filter 5. The partition plate 13, together with the guide column 3 and the inner wall of the oil collection hopper 2, forms an independent discharge chamber, which completely separates the material discharge area from the oil collection area to prevent the material from mixing with the oil. The discharge port 11 is connected to the discharge chamber, so that when the material is discharged, it directly enters the independent discharge space and does not come into contact with the oil in the oil collection hopper 2, ensuring the purity of the oil and the cleanliness of the material. This achieves complete separation of draining, discharge and oil collection, avoiding cross-contamination.

[0018] Please see Figure 1 , Figure 2 and Figure 4 An ultrasonic generator 19 is provided on the outer surface of the leaching tank 1. The ultrasonic generator 19 is electrically connected to the ultrasonic vibrator 4. The upper end of the ultrasonic vibrator 4 abuts against the lower end of the grid filter 5. The vibration frequency of the ultrasonic vibrator 4 is adjustable in the range of 20kHz-50kHz. An annular pressure plate 10 for positioning multiple irregular springs 9 is provided on the upper end of the oil collecting hopper 2. The lower end of the annular pressure plate 10 is detachably connected to the upper end of the multiple irregular springs 9. Two sets of ear plates 20 are arranged in annular array on the inner wall of the annular pressure plate 10. The number of ear plates 20 in one set is the same as the number of irregular springs 9. The lower end of the ear plates 20 corresponds one-to-one with the upper end of the multiple irregular springs 9 and is connected by bolts. The upper ends of the other set of ear plates 20 are all bolted to the inner wall of the leaching tank 1. Through the above technical solution, the ultrasonic generator 19 can convert electrical energy into a high-frequency electrical signal, providing a stable driving force for the ultrasonic vibrator 4. Simultaneously, the ultrasonic generator 19 can adjust the frequency of its output signal to match the adjustment range of the ultrasonic vibrator 4 (20kHz to 50kHz). Vibration parameters are optimized according to material characteristics such as particle size, oil content, and humidity. For example, for fine, lightweight materials, the frequency and power are reduced to prevent material dispersion; for dense, blocky materials, the frequency and power are increased to enhance vibration penetration, ensuring optimal draining effect for different materials. The lower end of the irregularly shaped spring 9 is connected to the upper end of the false bottom 7, and the upper end is bolted to the ear plate 20 of the annular pressure plate 10. During use, the false bottom 7 moves upward due to vibration, and the irregularly shaped spring 9... The elasticity of the material can prevent excessive compression and clumping. The inner wall of the annular pressure plate 10 is equipped with two sets of ear plates 20 in annular array. One set is bolted to the irregular spring 9 one by one, providing the upper fixing point of the irregular spring 9. At the same time, the initial compression of the irregular spring 9 is finely adjusted by the tightness of the bolts to control the initial pressure on the false bottom 7. The other set is bolted to the inner wall of the extractor 1 to fix the annular pressure plate 10 to the lower end of the extractor 1. The annular pressure plate 10 adopts an annular structure to match the upper opening size of the oil collection hopper 2, so as not to block the channel of material falling from the extractor 1 into the false bottom 7, ensuring that the material can be evenly distributed on the false bottom 7. The annular design also ensures uniform circumferential force and avoids deformation of the annular pressure plate 10 or the false bottom 7 due to local stress concentration, thus ensuring the stability of the draining process.

[0019] Example 2: Please refer to Figure 1 and Figure 2 This utility model provides a technical solution based on Embodiment 1. A negative pressure pipe 15 is detachably connected to the outer surface of the oil collecting hopper 2. The negative pressure pipe 15 is connected to the interior of the oil collecting hopper 2, and a control valve 16 is detachably connected to the upper end of the negative pressure pipe 15. An oil outlet pipe 17 is provided on the side of the outer surface of the oil collecting hopper 2 away from the negative pressure pipe 15. Multiple support feet 18 are arranged in a ring array at the lower end of the oil collecting hopper 2. Anti-slip textures are provided at the lower end of the multiple support feet 18. The upper end of the extractor 1 is connected to the feed pipe 21 through a flange. A spray pipe 22 is provided on the side of the upper end of the extractor 1 near the feed pipe 21, and the output end of the spray pipe 22 faces the interior of the extractor 1. Through the above technical solution, the other end of the negative pressure pipe 15 can be connected to an external vacuum pump or other negative pressure equipment. By drawing a vacuum, a negative pressure environment is formed in the oil collecting hopper 2. This, in conjunction with ultrasonic vibration, accelerates the separation and penetration of oil in the material. The control valve 16 is installed at the upper end of the negative pressure pipe 15. The opening degree of the control valve 16 is adjusted to control the opening and closing of the negative pressure pipe 15 and the negative pressure intensity. For example, it is opened at the beginning of draining and adjusted to a suitable opening degree to enhance oil separation. It is closed after draining to prevent outside air from entering the oil collecting hopper 2 and to avoid oil oxidation or material moisture absorption. The other end of the oil outlet pipe 17 can be connected to... External oil storage tanks or refining equipment enable oil recovery and subsequent processing. The support legs 18 are arranged in a ring array at the lower end of the oil collection hopper 2. Through multi-point uniform support, the overall stability of the device is ensured, avoiding tilting due to the shift of the center of gravity. The height of the support legs 18 is adapted to the needs of the production scene. The lower end of the support legs 18 is provided with anti-slip texture to increase the friction with the ground, reduce the displacement of the device during ultrasonic vibration, and ensure production safety. The feed pipe 21 can transport external materials to the interior of the leaching tank 1. The spray pipe 22 can transport leaching solvent or cleaning liquid according to process requirements.

[0020] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power via standard interfaces. The main controller can be any commercially available known device. There are no special restrictions on the specific models of the electrical components; any commercially available ordinary products can be selected, as long as they meet the usage requirements of this utility model.

[0021] In this invention, the working steps of the device are as follows: First, the leachable material to be drained is fed into the feed pipe 21 at the top of the leachator 1 via an upstream conveying device. This allows the material to fall steadily into the interior of the leachator 1 along the feed pipe 21 and be evenly distributed on the false bottom 7, preventing local accumulation of material on the false bottom 7. Simultaneously, the corresponding liquid is transported through the spray pipe 22 at the top of the leachator 1. During the spraying process, the movable plate 12 is kept closed to form a closed draining space. The ultrasonic generator 19 is activated, converting electrical energy into a high-frequency electrical signal that is transmitted to the ultrasonic vibrator 4. The ultrasonic vibrator 4 generates a high-frequency vibration at a set frequency. This vibration is transmitted to the entire grid filter 5 through contact with the lower end of the grid filter 5, and then to the false bottom 7 through the ball spring 6 and the telescopic rod 8, causing the false bottom 7 to generate synchronized micro-vibrations. The control valve 16 on the negative pressure pipe 15 is slowly opened, and a vacuum is drawn by an external vacuum pump, creating a negative pressure environment in the oil collection hopper 2. The negative pressure accelerates the penetration of the mixed oil into the oil collection area while preventing the mixed oil from accumulating. The mixed oil remains on the surface of the grid filter screen 5 and falls into the oil collection hopper 2. It then flows rapidly to the bottom of the oil collection hopper 2 along the guide groove on the outer surface of the guide column 3 and is temporarily stored in the oil collection area, awaiting subsequent discharge. During this process, the discharge chambers enclosed by the two symmetrical baffles 13 on the outer surface of the guide column 3 remain independent to ensure that the oil does not come into contact with the discharge chambers and to avoid cross-contamination. The movable plate 12 of the discharge port 11 of the false bottom 7 is opened, and the drained material on the false bottom 7 falls into the discharge chamber enclosed by the baffles 13 under its own gravity through the corresponding discharge ports 11 of the upper and lower false bottom 7 and the discharge port 11 of the grid filter screen 5. After the material accumulates in the discharge chamber, it is discharged along the discharge pipe 14 at the lower end of the oil collection hopper 2 and connected to the downstream processing equipment to complete the material discharge. After the material is completely discharged, the valve of the oil outlet pipe 17 is opened, and the mixed oil temporarily stored in the oil collection area of ​​the oil collection hopper 2 is stably discharged along the oil outlet pipe 17 and connected to the oil storage tank or subsequent refining equipment to realize the recycling of the oil.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
