Description

Technical Field

[0001] This utility model relates to the field of grease filtration technology, and in particular to a coarse sorting device. Background Technology

[0002] During the recycling of waste oil, large debris (such as plastic bags, plastic bottles, etc.) needs to be picked out first to prevent a large amount of large debris from entering the receiving tank. Heavy debris will settle at the bottom of the receiving tank, increasing the frequency of manual cleaning. Large debris can also easily cause blockage and wear on downstream pipeline equipment.

[0003] Most existing waste oil recycling devices use a grating plate at the inlet of the receiving trough. Waste oil is poured in through the inlet, and the grating plate separates large pieces of debris. However, this separated debris requires manual cleaning, which easily causes oily liquid to drip and spill, leading to poor on-site hygiene and uncontrollable odors. Furthermore, in colder seasons, waste oil easily freezes and solidifies, reducing its fluidity and clogging the grating holes, making feeding difficult and affecting filtration efficiency.

[0004] Therefore, there is an urgent need for a coarse sorting device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a coarse sorting device to avoid manual cleaning of large debris, ensure the hygiene of the working environment, prevent clogging of the feed inlet, and improve sorting efficiency.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model provides a coarse sorting device, which includes a receiving bin, a first heating component, a sorting component, and a driving component. The receiving bin is used to hold the grease to be sorted; the first heating component is disposed in the receiving bin; the sorting component includes a conveying housing and a screw conveyor; the extension direction of the conveying housing is at an angle to a first direction, which is horizontal; the conveying housing is connected to the receiving bin; the screw conveyor is disposed inside the conveying housing, and the extension direction of the screw conveyor is parallel to the extension direction of the conveying housing; the conveying housing has a first outlet and a second outlet; in a second direction, the first outlet is located above the second outlet; the second direction is at an angle to the first direction; the driving component is disposed outside the conveying housing and is drively connected to the screw conveyor; the driving component can drive the screw conveyor to rotate around its own axis to transport impurities in the grease to be sorted to the first outlet.

[0008] In some embodiments, a communication port is provided between the receiving bin and the conveying housing; the sorting assembly further includes a filter element; the filter element is disposed inside the conveying housing and located on the side of the spiral conveyor opposite to the communication port.

[0009] In some embodiments, the filter element has a semi-circular cross-sectional shape; the spiral conveyor is at least partially surrounded by the filter element.

[0010] In some embodiments, the extension direction of the filter element is parallel to the extension direction of the spiral conveyor; the length of the filter element is the same as the length of the spiral conveyor.

[0011] In some embodiments, the angle between the extending direction of the conveying housing and the first direction is a first angle; the angle range of the first angle is 15° to 45°.

[0012] In some embodiments, the receiving bin is provided with a feed inlet; a second heating component is provided at the feed inlet.

[0013] In some embodiments, the opening direction of the feed inlet is set at an angle to the second direction.

[0014] In some embodiments, the angle between the opening direction of the feed inlet and the second direction is a second angle; the angle range of the second angle is 15° to 45°.

[0015] In some embodiments, in the second direction, the upper end of the receiving bin is the first end, and the lower end of the receiving bin is the second end; in the first direction, the size of the first end is larger than the size of the second end.

[0016] In some embodiments, the cross-sectional shape of the receiving bin is an inverted triangle; the cross-section is parallel to the XY plane.

[0017] The beneficial effects of this utility model are:

[0018] This utility model provides a coarse sorting device. By installing a first heating component on the receiving bin, the device heats the grease to be sorted contained inside the bin, preventing solidification of the grease inside the receiving bin due to low temperature, improving the fluidity of the grease, and thus increasing sorting efficiency. Furthermore, a sorting assembly including a conveying shell and a screw conveyor is provided. The extension direction of the conveying shell is set at an angle to a first direction, and the screw conveyor is placed inside the conveying shell, with its extension direction parallel to that of the conveying shell. Additionally, a first discharge port and a second discharge port are provided on the conveying shell, with the first discharge port positioned higher than the second discharge port. A drive assembly is connected to the screw conveyor for transmission. When the drive assembly drives the screw conveyor to rotate around its own axis, impurities located in the helical gap of the screw conveyor are carried by the helical gap and moved along the extension direction of the screw conveyor, thus conveying the impurities to the first discharge port for discharge, while the grease is discharged from the second discharge port, thereby achieving coarse sorting of the grease. During the coarse sorting process of grease using the aforementioned coarse sorting device, impurities in the grease to be sorted are automatically conveyed to the first discharge port by the inclined screw conveyor in the sorting component. This eliminates the need for manual cleaning of the sorted impurities, preventing them from being exposed to the working environment and avoiding grease dripping onto the working environment, thus saving manpower and ensuring a hygienic working environment. Simultaneously, the coarse sorting device is also equipped with a first heating component, which prevents the grease to be sorted from solidifying in the receiving hopper when the temperature is too low, thus avoiding blockage. This eliminates the need for frequent manual unblocking of the receiving hopper, further saving manpower and improving sorting efficiency. Furthermore, during the coarse sorting process, due to the inclined design of the screw conveyor, the grease attached to the impurities flows along the inner wall of the conveyor housing to the second discharge port under gravity, preventing excessive grease from adhering to the impurities and further preventing grease dripping into the working environment, ensuring a hygienic working environment.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0026] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0028] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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.

[0029] like Figure 1As shown, this embodiment provides a coarse sorting device, which includes a receiving bin 1, a first heating component 2, a sorting component 3, and a driving component 4.

[0030] The aforementioned receiving hopper 1 is used to hold the grease to be sorted (e.g., waste grease containing large pieces of debris). For example, as shown... Figure 2 As shown, in the second direction Y, the upper end of the receiving bin 1 is the first end 12, and the lower end is the second end 13. Meanwhile, in the first direction X, the size of the first end 12 of the receiving bin 1 is larger than the size of the second end 13. Here, the first direction X is, for example, horizontal, and the second direction Y forms an angle with the first direction X, for example, 90°. In other words, the sidewall of the receiving bin 1 is inclined, and the receiving bin 1 has an overall structure that is larger at the top and smaller at the bottom (e.g., an inverted cone shape). For example, the cross-section of the receiving bin 1 is an inverted triangle, parallel to the XY plane, where the "XY plane" is the plane formed by the first direction X and the second direction Y. Through this arrangement, the grease to be sorted contained inside the receiving bin 1 can accumulate at the bottom of the receiving bin 1 under the action of gravity and the guiding effect of the inclined sidewall, facilitating the complete discharge of the grease and preventing residue from remaining inside the receiving bin 1.

[0031] like Figure 1 , Figure 2 As shown, the first heating component 2 is disposed on the receiving bin 1. For example, the first heating component 2 is disposed on the outer wall of the receiving bin 1. The heat source of the first heating component 2 can be any heat source with thermal energy, such as steam, hot water, electricity, or flue gas. Those skilled in the art can flexibly configure it according to actual usage requirements, which will not be described in detail here.

[0032] Combination Figure 2 , Figure 3As shown, the sorting assembly 3 includes a conveying housing 31 and a screw conveyor 32. The extending direction of the conveying housing 31 is angled with the first direction X, which is, for example, a horizontal direction. The conveying housing 31 communicates with the receiving bin 1, allowing the grease to be sorted inside the receiving bin 1 to flow into the conveying housing 31. The screw conveyor 32 is disposed inside the conveying housing 31, and its extending direction is parallel to that of the conveying housing 31. It is easy to understand that, in order to house the screw conveyor 32 inside the conveying housing 31, a cylindrical conveying channel is provided within the conveying housing 31, and this cylindrical conveying channel is adapted to the screw conveyor 32; that is, the inner diameter of the cylindrical conveying channel is the same as or larger than the outer diameter of the screw conveyor 32. The screw conveyor 32 can be a helical blade or a helical conveying rod (i.e., a helical blade wound around a rod-like object). Those skilled in the art can flexibly configure it according to actual usage requirements, which will not be described in detail here.

[0033] like Figure 2 As shown, the conveying housing 31 has a first discharge port 311 and a second discharge port 312. In the second direction Y, the first discharge port 311 is located above the second discharge port 312, where the second direction Y forms an angle with the first direction X, for example, 90°. The first discharge port 311 is used to discharge impurities conveyed by the screw conveyor 32, and the second discharge port 312 is used to discharge coarsely sorted grease. It is easy to understand that in order for the impurities conveyed by the screw conveyor 32 to be discharged from the first discharge port 311, one end of the screw conveyor 32 should be directly opposite the first discharge port 311. Furthermore, to control the discharge of coarsely sorted grease from the second discharge port 312, a valve can be installed at the second discharge port 312 to achieve flexible control of grease discharge.

[0034] like Figure 1 , Figure 2As shown, the drive assembly 4 is disposed outside the conveying housing 31 and is connected to the screw conveyor 32 in a transmission manner. The drive assembly 4 is, for example, a rotary motor. It can be directly connected to the screw conveyor 32 (e.g., the output shaft of the rotary motor is directly connected to the screw conveyor 32 via a coupling). Alternatively, the drive assembly 4 can be connected to the screw conveyor 32 via other transmission components (e.g., transmission gears or transmission pulleys). Those skilled in the art can flexibly configure the drive assembly according to actual usage requirements, which will not be described in detail here. The drive assembly 4 can drive the screw conveyor 32 to rotate around its own axis to transport impurities in the grease to be sorted to the first discharge port 311, thereby discharging the impurities from the first discharge port 311. Specifically, the impurities in the grease to be sorted fall into the helical gap (between two adjacent helical blades) on the screw conveyor 32 under gravity. As the screw conveyor 32 rotates, the impurities are driven by the helical gap on the screw conveyor 32, moving along the extension direction of the screw conveyor 32, thereby achieving the sorting of the impurities.

[0035] Therefore, the coarse sorting device provided in this embodiment can heat the oil to be sorted contained in the receiving bin 1 by setting a first heating component 2 on the receiving bin 1, so as to avoid the oil to be sorted from solidifying in the receiving bin 1 when the temperature is too low, improve the fluidity of the oil to be sorted, and thus improve the sorting efficiency. In addition, a sorting component 3 including a conveying shell 31 and a screw conveyor 32 is also provided. The extension direction of the conveying shell 31 is set at an angle with the first direction X, and the screw conveyor 32 is set inside the conveying shell 31, with the extension direction of the screw conveyor 32 parallel to the extension direction of the conveying shell 31. In addition, a first discharge port 311 and a second discharge port 312 are opened on the conveying shell 31, and the position of the first discharge port 311 is set higher than that of the second discharge port 312. A drive component 4 is provided to drive the screw conveyor 32. When the drive assembly 4 drives the screw conveyor 32 to rotate around its own axis, the debris located in the screw gap of the screw conveyor 32 will be driven by the screw gap and move along the extension direction of the screw conveyor 32, thereby conveying the debris to the first discharge port 311. The debris can be discharged from the first discharge port 311, and the grease will be discharged from the second discharge port 312, thus realizing the coarse separation of grease. In the process of using the above coarse separation device to perform coarse separation of grease, the debris in the grease to be separated will be automatically conveyed to the first discharge port 311 by the inclined screw conveyor 32 in the separation assembly 3, eliminating the need for manual cleaning of the separated debris. At the same time, there is no need to clean the debris at the feed inlet 11 of the receiving bin 1, avoiding the exposure of debris to the working environment and the dripping of grease from the debris into the working environment, saving manpower and ensuring the hygiene of the working environment. At the same time, the above coarse separation device is also equipped with a first heating assembly 2, which can prevent the temperature from being too low. When the grease to be sorted solidifies in the receiving hopper 1, causing blockage, there is no need for frequent manual unblocking of the receiving hopper 1, further saving manpower and improving sorting efficiency. In addition, during the coarse sorting process, since the screw conveyor 32 is set at an angle, when the screw conveyor 32 is conveying debris, the grease attached to the debris will flow along the inner wall of the conveying shell 31 to the second discharge port 312 under the action of gravity, avoiding excessive grease on the debris and further preventing grease from dripping into the working environment, thus ensuring the hygiene of the working environment.

[0036] In some embodiments, a communication port is provided between the receiving bin 1 and the conveying housing 31, through which the receiving bin 1 communicates with the conveying housing 31. Figure 2 , Figure 3 As shown, the sorting assembly 3 also includes a filter element 33. This filter element 33 is disposed inside the conveying housing 31, located on the side of the screw conveyor 32 opposite to the connecting port. In other words, the filter element 33 is disposed between the screw conveyor 32 and the second discharge port 312 on the conveying housing 31. That is, with... Figure 2Taking the shown perspective as an example, the filter element 33 is disposed on the lower side of the screw conveyor 32, and the second discharge port 312 is located on the lower side of the filter element 33. With this arrangement, the filter element 33 can be used to perform secondary filtration on the coarsely sorted grease, improving the filtration effect while ensuring that impurities are not discharged through the second discharge port 312. This ensures the grease sorting effect, prevents impurities from entering the downstream pipeline and causing blockage and wear of the downstream pipeline equipment, and improves the practicality of the coarse sorting device.

[0037] In some embodiments, the cross-sectional shape of the filter element 33 is semi-circular, and the cross-sectional direction is perpendicular to the extending direction of the filter element 33. The screw conveyor 32 is at least partially surrounded by the filter element 33. With this arrangement, the filter element 33 can surround the screw conveyor 32 to a certain extent, which can prevent impurities from being discharged from the side of the screw conveyor 32, thus improving the sorting effect of the coarse sorting device.

[0038] In some embodiments, the extending direction of the filter element 33 is parallel to the extending direction of the screw conveyor 32. Simultaneously, the length of the filter element 33 is the same as the length of the screw conveyor 32. This arrangement allows the filter element 33 to partially surround the entire screw conveyor 32, further preventing debris from being discharged from the sides of the screw conveyor 32 and further improving the sorting effect of the coarse sorting device.

[0039] In some embodiments, such as Figure 2 As shown, the angle between the extending direction of the conveying housing 31 and the first direction X is the first included angle α1, which ranges from 15° to 45°. For example, the first included angle α1 is 15°; or 20°; or 30°; or 35°; or 45°. By setting it in this way, the angle between the extending direction of the conveying housing 31 and the first direction X can be ensured to be within a suitable range, which can ensure the conveying effect of the screw conveyor 32, and also allow the grease attached to the debris to flow back to the second discharge port 312 by using the inclined conveying housing 31.

[0040] In some embodiments, such as Figure 2As shown, the aforementioned receiving hopper 1 is provided with a feed inlet 11, and a second heating component 5 is installed at the feed inlet 11. Similar to the first heating component 2, the heat source of the second heating component 5 can be any heat source with thermal energy, such as steam, hot water, electricity, or flue gas. Those skilled in the art can flexibly configure it according to actual usage requirements, which will not be described in detail here. With this configuration, the second heating component 5 can be used to heat the feed inlet 11 of the receiving hopper 1, preventing the grease from becoming less fluid and solidifying at the opening of the feed inlet 11 in an environment of excessively low temperature, thus ensuring feeding efficiency.

[0041] In some embodiments, the opening direction of the feed inlet 11 is set at an angle to the second direction Y. This arrangement facilitates the addition of the grease to be sorted into the receiving bin 1, while also preventing grease from splashing at the feed inlet 11 to a certain extent.

[0042] For example, such as Figure 2 As shown, the angle between the opening direction of the feed inlet 11 and the second direction Y is the second included angle α2, which ranges from 15° to 45°. For example, the angle of the second included angle α2 is 15°; or 20°; or 30°; or 35°; or 45°. By setting it in this way, it can be ensured that the angle between the opening direction of the feed inlet 11 and the second direction Y is within a suitable range, making it convenient to add the oil to be sorted into the receiving bin 1 through the feed inlet 11.

[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
