Description

Technical Field

[0001] This invention relates to the field of coffee processing technology, and in particular to a coffee filtration system. Background Technology

[0002] Coffee, with its fragrant and delicious aroma, is an indispensable beverage in modern life. Many substances in coffee are water-soluble, such as fruit acids, caffeine, and oils. Coffee extraction is the process of extracting these water-soluble substances from coffee. According to years of research by coffee professionals, it is generally believed that only 30% of the substances in coffee are soluble, while 70% are insoluble carbohydrates. The coffee processing involves filtering the steeped coffee grounds, collecting the coffee liquid for concentration and drying. During filtration, a large amount of coffee grounds is generated. These grounds are inconvenient to transport and are usually transported manually, which is inefficient. Using conveyor belts would require long conveyor belts, increasing costs.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] In the description of this invention, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0029] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

[0030] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0031] Example: A coffee filtration system, such as Figures 1 to 7 As shown, the system includes a primary filter assembly 1, a secondary filter assembly 2, and a tertiary filter assembly 3. The primary filter assembly 1 is connected to the secondary filter assembly 2, the secondary filter assembly 2 is connected to a first storage tank 4, and the first storage tank 4 is connected to the tertiary filter assembly 3. In this embodiment, the tertiary filter assembly 3 is a tubular centrifuge to improve the filtration effect. The tertiary filter assembly 3 is connected to a second storage tank 5. The filter first passes through the primary filter assembly 1 and the secondary filter assembly 2, then is stored in the first storage tank 4, then passes through the tertiary filter assembly 3, and finally is stored in the second storage tank 5, thus solving the problem of slow filtration in tubular centrifuges.

[0032] The primary filtration assembly 1 includes a tank 11, a feed inlet 12, a support frame 13, a stirring assembly 14, a cover 15, an opening assembly 16, a locking assembly 17, a filter plate 18, a filter membrane 19, and a conveying assembly 6. The feed inlet 12 is located at the upper end of the tank 11, the tank 11 is mounted on the support frame 13, the stirring assembly 14 is mounted on the tank 11, the lower end of the tank 11 is provided with a slag discharge port 111, the cover 15 is mounted on the slag discharge port 111, the opening assembly 16 and the locking assembly 17 are mounted on the tank 11 and work together with the cover 15. The opening assembly 16 is used to open the cover 15, and the locking assembly 17 is used to lock the cover 15. The filter plate 18 is located at the upper end of the cover 15, the filter membrane 19 is detachably mounted at the upper end of the filter plate 18, and the lower end of the cover 15 is provided with a first drain pipe 151 and a second drain pipe 152. Hot water and coffee powder are mixed in the tank 11, stirred by the stirring assembly 14, filtered through the filter plate 18 and filter membrane 19, and discharged into the secondary filter assembly 2 through the first drain pipe 151 and the second drain pipe 152.

[0033] The material conveying assembly 6 includes a receiving trough 61, a water inlet pipe 62, a conveying pipe 63, and a water pump 64. The receiving trough 61 is located below the slag discharge port 111 and is fixed to the support frame 13. The receiving trough 61 is inclined. The water inlet pipe 62 is connected to the higher end of the receiving trough 61, and one end of the conveying pipe 63 is connected to the lower side of the lower end of the receiving trough 61. The water pump 64 is mounted on the conveying pipe 63. Several water inlets 65 connected to the water inlet pipe 62 are horizontally arranged at the higher end of the receiving trough 61. A water-blocking plate 66 is provided above the water inlets 65. One end of the water-blocking plate 66 is connected to the inner wall of the receiving trough 61, and the other end of the water-blocking plate 66 is a free end. Specifically, when coffee grounds need to be discharged, simply open the cover 15 and discharge the coffee grounds into the receiving trough 61. Since the coffee grounds are already wet, they mix quickly with water. Then, a water pump 64 and a conveying pipe 63 transport the mixture to a recycling point. The recycling point can include a filter tank (not shown in the diagram) and a collection tank (not shown in the diagram) to filter out the wastewater from the coffee grounds and allow it to flow into the collection tank for easy recycling. The water in the inlet pipe 62 can be wastewater from other processes or wastewater from the collection tank. The water in the inlet pipe 62 enters evenly from the inlet 65, and a water-blocking plate 66 prevents splashing caused by excessive water pressure. The conveying pipe 63 can be arranged according to the terrain, making it highly adaptable.

[0034] The opening component 16 includes an automatic telescopic rod 161, a support rod 162, a first rotary joint 163, a second rotary joint 164, a drain pipe 165, a first stop valve 166, a connecting pipe 167, and a second stop valve 168. One end of the support rod 162 is connected to the lower middle part of the cover 15, and the other end of the support rod 162 is rotatably connected to the lower end of the automatic telescopic rod 161. The upper end of the automatic telescopic rod 161 is rotatably connected to the tank 11. Specifically, in this embodiment, the automatic telescopic rod 161 is a cylinder. The support rod 162 is rotatably connected to the tank body 11 near the automatic telescopic rod 161. The first drain pipe 151 and the second drain pipe 152 are symmetrically arranged on the left and right sides of the support rod 162. The first rotary joint 163 and the second rotary joint 164 are respectively located at the rotatable connection between the support rod 162 and the tank body 11. The first drain pipe 151 is connected to the first rotary joint 163. The other end of the first rotary joint 163 is connected to the sewage pipe 165. The sewage pipe 165 is equipped with a first stop valve 166. The second drain pipe 152 is connected to the second rotary joint 164. The other end of the second rotary joint 164 is connected to the connecting pipe 167. The second stop valve 168 is located on the connecting pipe 167. The other end of the connecting pipe 167 is connected to the secondary filter device. The end of the receiving trough 61 near the automatic telescopic rod 161 is higher than the other end, so that the opening direction of the cover 15 is towards the lower end of the receiving trough 61 to collect coffee grounds. Specifically, the extension and retraction of the automatic telescopic rod 161 rotates the support rod 162, which in turn drives the cover 15 to rotate, thus opening and closing the cover 15. The first drain pipe 151 and the second drain pipe 152 can rotate together with the support rod 162 due to the first rotary joint 163 and the second rotary joint 164, while other components remain stationary, making it convenient to open the cover 15. The first drain pipe 151 can open the first stop valve 166 to discharge the residual sewage in the tank 11.

[0035] The locking assembly 17 includes a fixing ring 171 and a rotating mechanism. The fixing ring 171 is located on the periphery of the slag discharge port 111. A connecting ring 172 is located on the periphery of the slag discharge port 111. An annular groove 173 is formed on the inner wall of the fixing ring 171. The connecting ring 172 is located in the annular groove 173. Several downward through grooves 174 are evenly formed at the lower end of the annular groove 173. A sealing ring 175 matching the slag discharge port 111 is provided at the upper end of the cover 15. Several fixing blocks 176 matching the through grooves 174 are evenly formed on the periphery of the cover 15. The rotating mechanism is located on the tank body 11. The rotating mechanism is used to rotate the fixing ring 171. The fixing blocks 176 can be inserted into the through grooves 174 and fixed by rotating the fixing ring 171. The locking assembly 17 has two states. In one state, the through groove 174 on the fixing ring 171 corresponds to the position of the fixing block 176, and the locking assembly 17 is in the open state. In the other state, the through groove 174 on the fixing ring 171 is misaligned with the position of the fixing block 176, and the locking assembly 17 is in the locked state. Meanwhile, the cover 15 forms a seal with the slag discharge port 111 through the sealing ring 175.

[0036] The fixed ring 171 has several gear teeth 177 on its circumference. The rotating mechanism includes a rotating motor 71 and a gear 72. The rotating motor 71 is mounted on the tank body 11, and the gear 72 is mounted on the output shaft of the rotating motor 71. The gear 72 meshes with the gear teeth 177. The rotating mechanism drives the gear 72 to rotate via the rotating motor, thereby driving the fixed ring 171 to rotate, thus forming two working states: locking and unlocking. Of course, other rotating mechanisms can also be used.

[0037] The secondary filter assembly 2 includes multiple cylindrical bodies 21 with openings at the top. Each cylindrical body 21 has a cover 22 at its opening end, and each cover 22 is connected to a connecting pipe 167. A filter bag 23 is installed inside each cylindrical body 21, and the lower end of each cylindrical body 21 is connected to the first storage tank 4. The secondary filter assembly 2 filters through the filter bag 23. Because there is less residue, the number of times the residue needs to be cleaned is reduced. Of course, the residue filtered by the secondary filter assembly 2 and the tertiary filter assembly 3 can be directly disposed of into the receiving trough 61.

[0038] The upper end of the tank 11 is provided with a pressurization port 112, which is connected to a pressurization pipe 8. The other end of the pressurization pipe 8 is connected to an air pressurization pump 9. The air pressurization pump 9 can effectively improve the filtration efficiency, and the coffee grounds discharged from the discharge port 111 are also drier, indicating thorough filtration. Moreover, when it is necessary to clean the tank 11, the wastewater can be pressurized and discharged from the first drain pipe 151.

[0039] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
