A continuous rice slag filtration device

Abstract

This utility model discloses a continuous rice lees filtration device, which mainly includes a receiving tank, a solid material box, a filter cylinder, an extruder, a spiral blade, and a drive motor. The drive motor drives the extruder and the spiral blade to rotate synchronously, lifting the rice lees mixture upward. During the lifting process, the rice lees mixture is squeezed against the inner wall of the filter cylinder as the extruder expands, thereby squeezing out the liquid inside and filtering it through the filter cylinder before it flows into the receiving tank. This utility model solves the problem of cumbersome rice lees filtration steps and the inability to achieve continuous filtration in the rice wine production process, which can effectively improve the rice wine production efficiency and reduce the production cost of the rice lees filtration process.

Description

Technical Field

[0001] This application relates to the field of rice wine production technology, specifically to a continuous rice lees filtration device. Background Technology

[0002] Rice lees filtration devices are key equipment in the brewing industry of rice wine, huangjiu, and other rice wines, used for solid-liquid separation of fermented rice lees. Their main function is to efficiently extract residual wine juice from the lees, increasing the yield and ensuring product quality. Traditional manual methods combine bag filtration with pressing, requiring operators to fill the bags with rice lees in batches and squeeze out the juice using heavy pressure or levers. This method is not only labor-intensive but also inefficient. Modern mechanical devices increasingly use hydraulic pressing devices, extracting the juice through powerful pressure from hydraulic plates.

[0003] However, existing technologies still struggle to overcome the bottleneck of production continuity: traditional manual extraction methods require multiple loading and unloading of cloth bags and collection of multiple batches of filtered juice (often more than 10 boxes) to meet the requirements of a single process. This not only results in high labor costs and cumbersome material handling, but also interrupts subsequent processes due to the inability to supply sufficient filtered juice in real time. Currently used mechanical rectangular pressing equipment filters the rice residue by squeezing or using pneumatic pressure on the filter screen, and collects and transports the solids from the rice residue using an inclined filter screen and a conveyor hopper. While this increases the throughput per batch, it is limited by an intermittent operation mode—after each batch of pressing, the machine must be stopped to unload the residue, clean, and reload, making it difficult to achieve seamless integration with continuous brewing production lines. The filtration pace is much slower than the fermentation capacity, necessitating additional storage tanks and manpower to compensate for capacity gaps, ultimately leading to a comprehensive waste of energy, time, and materials.

[0004] Therefore, this application proposes a continuous rice lees filtration device that can perform continuous filtration by gradually applying pressure during the spiral transport of the rice lees solid-liquid mixture and using a cylindrical filter screen, and whose filtration speed can be controlled according to the actual situation of the production line. Utility Model Content

[0005] The purpose of this invention is to provide a continuous rice dregs filtration device to solve the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a continuous rice slag filtration device, comprising: A container with a solid material box welded to its upper part; the upper part of the container is open and the lower end is bolted to the ground. The filter cartridge is fixedly installed at the bottom wall of the receiving tank at the lower end and fixedly connected to the lower part of the solid material box at the upper end. A feed pipe is fixedly connected to the side of the filter cartridge. The extruder is rotatably connected to the bottom wall of the receiving tank and extends downward through the bottom wall of the receiving tank. The rotatable connection is equipped with a dynamic seal. The extruder is located inside the filter cartridge and has a cylindrical structure with its diameter gradually increasing from bottom to top. Spiral blades; welded to the outer periphery of the extruder, with the outer side of the spiral blades contacting the inner wall of the filter cartridge; The drive motor is installed at the bottom of the container, and its output end is plugged into the lower end of the extruder. The drive motor drives the extruder and the spiral blade to rotate synchronously, lifting the rice residue mixture upwards. As the extruder expands during the lifting process, the rice residue mixture is squeezed against the inner wall of the filter cylinder, thereby squeezing out the liquid inside and allowing it to flow into the container after being filtered by the filter cylinder.

[0007] By using an extruder with gradually increasing diameter, in conjunction with a filter cylinder that contacts the spiral blades, the rice lees mixture is gradually compressed as it moves upward driven by the spiral blades. This forces the liquid inside out and allows it to flow into a collection tank for collection through filtration in the filter cylinder. This enables continuous, long-term compression filtration of the rice lees. Furthermore, by controlling the speed of the extruder, the filtration speed of the rice lees can be directly controlled. This technology can be directly applied to production lines to achieve continuous filtration of rice lees, effectively improving rice wine production efficiency and reducing labor costs.

[0008] Furthermore, the filter cartridge has a cylindrical structure and is made of alloy filter mesh welded together. The feed pipe passes through the container and is connected to the rice lees supply device. A seal is provided at the contact point between the feed pipe and the container. The lower part of the container has an inverted conical structure.

[0009] Furthermore, a drain pipe is connected to the side of the container, and a valve is installed at the drain pipe. An observation window and a control panel are installed at the front of the container, and the control panel is connected to the drive motor via electrical signals.

[0010] Furthermore, a rotating door is provided on the side of the solid material box. One end of the rotating door is hinged to the solid material box, and the other end of the rotating door is snapped into the lower part of the solid material box. An auxiliary rod is welded and fixed inside the solid material box. The end of the auxiliary rod away from the inner wall of the solid material box is rotatably connected to the upper end of the extruder. A through hole is opened on the bottom wall of the solid material box so that the solid material box is connected to the inside of the filter cartridge.

[0011] Compared with existing technologies, it has the following beneficial effects: This invention provides a continuous rice lees filtration device. Through a gradually increasing diameter extruder, coupled with a filter cylinder in contact with a spiral blade, the rice lees mixture is gradually compressed as it moves upwards driven by the spiral blade. This forces the liquid inside out and allows it to flow through the filter cylinder into a collection tank for collection. This enables continuous, long-term compression filtration of the rice lees. Furthermore, the filtration speed can be directly controlled by adjusting the extruder's rotation speed. This device can be directly applied to production lines to achieve continuous rice lees filtration, effectively improving rice wine production efficiency and reducing labor costs.

[0014] 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 protection scope of the present utility model.

[0015] Please see Figures 1 to 4 As shown, this utility model provides the following technical solution: a continuous rice slag filtration device; comprising: The container 1 has a solid material box 2 welded to its upper part. The upper part of the container 1 is open and the lower end is bolted to the ground. The container 1 adopts a cylindrical structure and can be directly connected to the production line. Alternatively, it can adopt a lockable universal wheel design to make the container 1 easy to move to different positions for rice lees filtration.

[0016] The filter cartridge 3 is fixedly installed at the bottom wall of the container 1 at the lower end and fixedly connected to the lower part of the solid material box 2 at the upper end. The feed pipe 31 is fixedly connected to the side of the filter cartridge 3. The extruder 4 is rotatably connected to the bottom wall of the container 1 and extends downward through the bottom wall of the container 1. The rotatable connection is equipped with a dynamic seal. The extruder 4 is located inside the filter cartridge 3. The extruder 4 has a cylindrical structure and its diameter gradually increases from bottom to top. The extruder 4 can adopt a hollow structure to reduce its weight. Its material is food-grade 304 stainless steel or other materials that meet food safety standards and have a certain strength.

[0017] Spiral blade 5 is welded to the outer periphery of extruder 4, and the outer side of spiral blade 5 is in contact with the inner wall of filter cylinder 3; wherein, the farthest position of the outer periphery of spiral blade 5 is always in contact with filter cylinder 3, and it is kept on the same vertical axis from bottom to top.

[0018] The drive motor 6 is installed at the bottom of the container 1, and its output end is plugged into the lower end of the extruder 4. The drive motor 6 is a variable speed servo motor, which adjusts the speed of the extruder 4. The change in the speed of the extruder 4 can control the upward movement speed of the rice and lees mixture, thereby controlling the filtration rate.

[0019] The drive motor 6 drives the extruder 4 and the spiral blade 5 to rotate synchronously, lifting the rice residue mixture upward. As the rice residue mixture is lifted, it is squeezed against the inner wall of the filter cylinder 3 as the extruder 4 expands, thereby squeezing out the liquid inside and filtering it through the filter cylinder 3 before flowing into the container 1.

[0020] It should be noted that the filter cartridge 3 has a cylindrical structure and is made of alloy filter mesh welded together to ensure the strength of the filter cartridge 3 and prevent it from deforming due to prolonged pressure from rice residue during use.

[0021] See Figure 2 as well as Figure 3 The feed pipe 31 passes through the container 1 and is connected to the rice lees supply device. A seal is provided at the contact point between the feed pipe 31 and the container 1. The solid-liquid mixture of rice lees is driven by a mixing pump into the feed pipe 31 and then enters the filter cartridge 3 through the feed pipe 31. After the rice residue mixture enters the filter cylinder 3, it is driven by the rotating spiral blade 5 to move upward along the length of the filter cylinder 3. During the movement, the liquid flows out through the filter cylinder 3. The gradually widening extruder 4 continuously squeezes the rice residue, squeezing out the liquid inside and filtering it through the filter cylinder 3 into the container 1.

[0022] As another embodiment, such as Figures 1 to 3 As shown, the lower part of the container 1 has an inverted conical structure, which allows the outflowing liquid to flow into the inverted conical groove, making it easier for subsequent discharge.

[0023] See Figure 1The side of the container 1 is also connected to a drain pipe 11, and a valve is installed at the drain pipe 11. The valve adopts a solenoid valve structure, which allows the discharge to be controlled by electrical control. The end of the drain pipe 11 can be connected to the pump body and connected to the next process, so that the device can directly enter the rice wine production line and continuously carry out rice lees filtration operation.

[0024] See Figure 1 The front of the container tank 1 is equipped with an observation window 12 and a control panel 13, which is electrically connected to the drive motor 6. The speed of the drive motor 6 can be directly controlled through the control panel 13, and the filtration rate can be adjusted according to the actual production conditions on site.

[0025] See Figure 1 A rotating door 21 is provided on the side of the solid material box 2. One end of the rotating door 21 is hinged to the solid material box 2, and the other end of the rotating door 21 is engaged with the lower part of the solid material box 2. During the filtration process, the rice residue solids are finally conveyed into the solid material box 2 by the spiral blades 5. The rice residue solids can be collected by opening the rotating door 21. At the same time, the solid rice residue in the solid material box 2 can also be automatically collected by a push plate or other means, further improving the automation level of the device.

[0026] See Figure 2 To ensure the stability of the extruder 4, an auxiliary rod 22 is welded and fixed inside the solid material box 2. The end of the auxiliary rod 22 away from the inner wall of the solid material box 2 is rotatably connected to the upper end of the extruder 4 to provide support for the extruder 4 and prevent it from deflecting.

[0027] See Figure 3 The bottom wall of the solid material box 2 has a through hole 23, so that the solid material box 2 is connected to the inside of the filter cartridge 3.

[0028] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
