Abstract
Description
Technical Field
[0001] This utility model relates to the field of recycling equipment technology, specifically a coffee grounds purification and recycling device. Background Technology
[0002] Coffee grounds are a byproduct of coffee extraction. Fresh coffee grounds have a high water content and contain a certain amount of coffee oil and other organic matter. If they are discarded directly, it will not only waste resources, but the oil and organic matter they contain may also pollute the environment.
[0003] Coffee grounds can be recycled to make compost or used as animal feed. Currently, most coffee grounds purification and recycling equipment removes some of the moisture from the coffee grounds through mechanical extrusion. Usually, the extruded grounds still need to be transferred to other equipment for drying. Moreover, for coffee grounds that clump together after extrusion, the subsequent drying efficiency will still be affected, resulting in low processing efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a coffee grounds purification and recycling device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a coffee grounds purification and recycling device, comprising a housing, a storage cylinder installed inside the housing, the top of the storage cylinder extending out of the housing, an mounting plate provided on the outer surface of the extended end of the storage cylinder, four second electric push rods provided inside the housing at the four corners of the bottom end of the mounting plate, a fine hole area provided at the bottom of the storage cylinder, a blower connected between two second electric push rods at the same end, a first motor provided at the top of the housing, a horizontal plate provided at the top of the first motor, a second motor provided at one end of the top of the horizontal plate, a rotating shaft provided at the bottom of the second motor, a plurality of stirring structures equidistantly arranged on the outer surface of the rotating shaft, a first electric push rod provided at the other end of the top of the horizontal plate, and a pressing disc provided at the bottom of the first electric push rod.
[0006] Preferably, the bottom of the housing is provided with four support feet, and dustproof grilles are provided on both sides of the housing near the fan. The support feet provide support for the housing and ensure the stability of the device. The fan is connected to the outside through the dustproof grilles. When the fan is running, it blows air into the storage cylinder to dry the coffee grounds inside quickly. The dustproof grilles block external dust and ensure the cleanliness of the inside of the housing.
[0007] Preferably, each of the four second electric push rods is provided with a locking element at its top end, and a through hole is provided at each of the four corners of the mounting plate. A threaded hole is provided at the middle of the top end of the locking element. When fixing the mounting plate, a bolt is inserted into the through hole to fix it, so that the mounting plate cannot move on its own.
[0008] Preferably, a number of stirring structures are evenly distributed on the outer surface of the bottom end of the rotating shaft. When the rotating shaft enters the bottom of the storage cylinder, the stirring structures come into contact with the squeezed coffee grounds. When the rotating shaft rotates, the stirring structures will disperse the squeezed coffee grounds, making it easier to air dry.
[0009] Preferably, a cavity is provided inside the shell near the fine pore area, and a liquid outlet is provided at the bottom of the shell below the storage cylinder. When the coffee grounds inside the storage cylinder are squeezed, some of the water and coffee oil in the coffee grounds are squeezed out of the coffee grounds, and the liquid falls from the cavity through the fine pore area into the liquid outlet.
[0010] Preferably, the extrusion disc is matched with the storage cylinder. When the extrusion disc moves downward, it will fully extrude the coffee grounds inside the storage cylinder, ensuring that the residual liquid in the coffee grounds is squeezed out.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This coffee grounds purification and recycling equipment uses an electric push rod to drive a special extrusion disc that applies pressure to the coffee grounds in the storage cylinder, efficiently separating water and coffee oil. Subsequently, the same equipment lifts the storage cylinder and activates the stirring and bottom stirring structures to break up the clumps of grounds. At the same time, a fan is used to ventilate and dry the material. There is no need to transfer materials, resulting in a high degree of automation, a short processing cycle, and higher efficiency.
[0013] 2. This coffee grounds purification and recycling equipment features a removable storage cylinder. The storage cylinder, through the cooperation of the mounting plate, through holes, and quick-release locking parts, enables rapid installation, positioning, and disassembly, facilitating loading, unloading, and cleaning, and effectively avoiding cross-contamination between different batches of materials.

[0018] 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.

They are used only for the convenience of describing this utility model 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 utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0020] like Figures 1 to 3As shown, the coffee grounds purification and recycling equipment of this embodiment includes a housing 1. A storage cylinder 13 is installed inside the housing 1, and coffee grounds can be placed inside the storage cylinder 13. The top of the storage cylinder 13 extends out of the housing 1. A mounting plate 10 is provided on the outer surface of the extended end of the storage cylinder 13. The mounting plate 10 limits the storage cylinder 13, preventing it from shifting independently. Four second electric push rods 14 are installed inside the housing 1 at the four corners of the bottom of the mounting plate 10. The four second electric push rods 14 support the mounting plate 10 and are controlled by the same control circuit. When their output ends extend simultaneously, they drive the storage cylinder 13 upward through the mounting plate 10. A fine-hole area 18 is provided at the bottom of the storage cylinder 13. The fine-hole area 18 can block coffee grounds without obstructing liquid seepage. A fan 17 is connected between two second electric push rods 14 at the same end. When the storage cylinder 13 rises, the fine-hole area 18 rises to the area of the fan 17. During operation, air is blown into the fine-hole area 18 to circulate air inside the storage cylinder 13, improving the drying efficiency of the coffee grounds. A first motor 2 is installed at the top of the shell 1, and a horizontal plate 7 is installed at the top of the first motor 2. When the first motor 2 is running, it drives the horizontal plate 7 to rotate. A second motor 5 is installed at one end of the top of the horizontal plate 7, and a rotating shaft 4 is installed at the bottom of the second motor 5. Several stirring structures 3 are evenly distributed on the outer surface of the rotating shaft 4. When the horizontal plate 7 is driven to rotate so that the rotating shaft 4 is directly above the storage cylinder 13, the storage cylinder 13 is driven to rise. At this time, the stirring structures 3 can stir the coffee grounds inside the storage cylinder 13. A first electric push rod 8 is installed at the other end of the top of the horizontal plate 7, and an extrusion plate 9 is installed at the bottom of the first electric push rod 8. The output end of the first electric push rod 8 can drive the extrusion plate 9 to move vertically and linearly, so that the extrusion plate 9 presses down on the coffee grounds inside the storage cylinder 13, squeezing out the water and coffee oil contained in the coffee grounds and discharging them through the fine-hole area 18.
[0021] Specifically, support legs 12 are provided at the four corners of the bottom of the housing 1, and dustproof grilles 11 are provided on both sides of the housing 1 near the fan 17. The support legs 12 provide support for the housing 1 to ensure the stability of the device. The fan is connected to the outside through the dustproof grilles 11. When the fan is running, it blows air into the storage cylinder 13 to dry the coffee grounds inside quickly. The dustproof grilles 11 block external dust and ensure the cleanliness of the inside of the housing 1.
[0022] Furthermore, each of the four second electric push rods 14 is provided with a locking element 19 at its top end, and each of the four corners of the mounting plate 10 is provided with a through hole 20. A threaded hole is provided at the middle position of the top end of the locking element 19. When fixing the mounting plate 10, a bolt is inserted into the through hole 20 to fix it, so that the mounting plate 10 cannot move on its own.
[0023] Furthermore, a number of stirring structures 6 are evenly distributed on the outer surface of the bottom end of the rotating shaft 4. When the rotating shaft 4 enters the bottom of the storage cylinder 13, the stirring structures 6 come into contact with the squeezed coffee grounds. When the rotating shaft 4 rotates, the tightly squeezed coffee grounds will be scattered through the stirring structures 6, making it easier to air dry.
[0024] Furthermore, a cavity 16 is provided inside the housing 1 near the fine hole area 18, and a liquid outlet 15 is provided at the bottom of the housing 1 below the storage cylinder 13. When the coffee grounds inside the storage cylinder 13 are squeezed, some of the water and coffee oil in the coffee grounds are squeezed out of the coffee grounds, and the liquid falls from the cavity 16 into the liquid outlet 15 through the fine hole area 18.
[0025] Furthermore, the extrusion disc 9 is matched with the storage cylinder 13. When the extrusion disc 9 moves downward, it will fully squeeze the coffee grounds inside the storage cylinder 13, ensuring that the residual liquid in the coffee grounds is squeezed out.
[0026] The usage method of this embodiment is as follows: When using the coffee grounds purification and recycling equipment, firstly, the collected wet coffee grounds are loaded into the storage cylinder 13. The first motor 2 is started, driving the horizontal plate 7 to rotate until the extrusion plate 9 at the bottom of the first electric push rod 8 moves directly above the storage cylinder 13. Then, the first electric push rod 8 is started, and its output end extends downward, pushing the extrusion plate 9 to move vertically downward and press it into the storage cylinder 13. The extrusion plate 9 applies pressure to the coffee grounds, squeezing out the water and coffee oil. The squeezed liquid seeps out through the fine hole area 18 at the bottom of the storage cylinder 13 and drips into the cavity 16 below. Finally, it gathers and flows out from the liquid outlet 15. A container is placed below the liquid outlet 15 to receive the recycled liquid. After the extrusion is completed, the first electric push rod 8 is controlled to retract, driving the extrusion plate 9 to rise and detach from the storage cylinder 13. The first motor 2 is started again, driving the horizontal plate 7 to rotate until the rotating shaft 4 at the bottom of the second motor 5 moves directly above the storage cylinder 13. Simultaneously, four second electric push rods 14 are activated, their output ends rising synchronously. This causes the entire storage cylinder 13 to rise via the mounting plate 10, raising the fine-pore area 18 of the storage cylinder 13 until it aligns with the air outlet of the blower 17. The second motor 5 is then activated, driving the rotating shaft 4 to rotate, which in turn drives the stirring structure 3 to agitate the upper layer of coffee grounds. At the same time, the bottom stirring structure 6 breaks up the coffee grounds that have been squeezed and clumped at the bottom, greatly increasing the fluffiness and surface area of the material. Simultaneously, the blower 17 is activated, drawing air through the dustproof grille 11 and blowing it towards the fine-pore area 18 of the storage cylinder 13. The strong air penetrates the broken-up coffee grounds layer, carrying away moisture. Stirring and blowing are continued for a period of time until the coffee grounds reach the required degree of dryness. After drying, the second motor 5 and the blower 17 are turned off, and the second electric push rods 14 are controlled to retract, lowering the storage cylinder 13 back to its initial position. The horizontal plate 7 is then removed, allowing the storage cylinder 13 to be manually removed and the dried coffee grounds to be poured out.
[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
