[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] At present, the difficulty and key point of pre-treatment of food waste is how to separate inorganic impurities from food waste as much as possible. Food waste has a high content of inorganic matter, which can be divided into light and heavy. If light impurities (such as plastics, fabrics, etc.) are not removed, they will form a thick scum cover in the subsequent post-treatment tank, blocking the gas in the tank from escaping, posing a safety hazard. Therefore, it is very necessary to remove floating matter in food waste filtrate.

[0004] In the prior art, the equipment for removing impurities from kitchen waste includes a sand-water separator, which mainly removes floating objects through a filter. The floating objects are easy to clog the filter due to the presence of the filter mesh. If the filter is not cleaned, the subsequent floating object treatment quality is poor and the treatment efficiency is low. If the filter is cleaned, the machine needs to be shut down, which delays the treatment work of the equipment and affects the normal use of the entire device. Summary of the invention

In addition, it should be understood that when the terms "include" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof;

[0039] As introduced in the background technology, in the prior art, floating matter in the filtrate is not easy to be removed and the removal efficiency is low. In order to solve the above technical problems, the present invention proposes a filtrate floating matter separation device.

[0040] Embodiment 1

[0041] In a typical embodiment of the present invention, reference is made to Figure 1 , Figure 2As shown, a filtrate floating object separation device comprises a shell 1, a space is formed inside the shell 1, a partition plate 2 is arranged in the shell 1 so that one side of the partition plate is a filtrate tank and the other side is a separation tank, the partition plate is arranged perpendicular to the bottom plate of the shell, the top of the partition plate 1 is arranged lower than the top of the shell to prevent the filtrate from exceeding the top of the shell, a plurality of slots are arranged on the top of the partition plate, a roller brush 3 is arranged in the shell 1 at a position lower than the slot in the separation tank, the roller brush is rotatable relative to the shell, a conveying component 4 is arranged in the shell at a position lower than the roller brush in the separation tank, a scraper 5 is arranged between the conveying component and the roller brush, one end of the scraper 5 contacts the roller brush 3, in the process of the filtrate in the filtrate tank flowing to the separation tank through the slot, the floating objects in the filtrate fall on the roller brush, and in the process of the rotation of the roller brush, the floating objects enter the conveying component under the action of the scraper.

[0042] In this embodiment, the roller brush 3 is provided at two locations, along the height direction of the housing, Figure 3 As shown, two roller brushes are arranged at the upper and lower parts, and both roller brushes can rotate toward the direction of the conveying component. The upper roller brush 3-1 and the lower roller brush 3-2 are arranged at a distance. The upper roller brush plays a role of primary filtering, and the lower roller brush plays a role of secondary filtering to filter out the debris left by the upper roller brush.

[0043] Specifically, the roller brushes 3 include a rotating roller, on which bristles are arranged in a circumferential direction. The bristles are multiple circles of stainless steel wire. A distance is set between two adjacent circles of stainless steel wire. Multiple stainless steel wires are arranged in each circle. The stainless steel wires are arranged along the radial direction of the rotating roller. The length of the stainless steel wires is greater than or equal to 5 mm. The stainless steel wires of the upper roller brush and the lower roller brush do not contact each other.

[0044] To match the corresponding roller brush 3, the natural scraper 5 is provided with two locations, namely the first scraper 5-1 and the second scraper 5-2. One end of the first scraper is inserted into the bristles of the upper roller brush, and the upper side of the first scraper is located on the side of the horizontal plane of the central axis of the upper roller brush, and does not contact the rotating roller of the roller brush. The other end of the first scraper is connected to the middle of the conveying component, and the other end of the second scraper 5-2 is inserted into the bristles of the lower roller brush, and the other end of the second scraper 5-2 is inserted into the side of the horizontal plane of the central axis of the lower roller brush. The other end of the second scraper is connected to the bottom side of the conveying component, the first scraper 5-1 is docked with the upper roller brush 3-1, and the second scraper is docked with the lower roller brush, so that floating objects falling on the two roller brushes are moved to the conveying component through the first scraper or the second scraper.

[0045] In this way, one end of the first scraper close to the upper roller brush is higher than the other end of the first scraper, and one end of the second scraper close to the lower roller brush is higher than the other end of the second scraper, so that floating objects can flow to the conveying component 4 under the action of inertia and gravity.

[0046] In this embodiment, the conveying component 4 is a spiral conveying mechanism, which is rotatable relative to the shell. The shell 1 can support the rotating shaft 4-2 of the spiral conveying mechanism through a bearing. The rotating shaft is placed on the side of the lower roller brush away from the partition plate. The spiral blade 4-1 is arranged circumferentially along the rotating shaft. The second scraper 5-2 and the third plate 6 form a V-shaped structure to close one side and the bottom side of the spiral conveying mechanism. The first scraper 5-1 and the second scraper 5-2 are arranged on one side of the spiral conveying mechanism, and the third plate 6 is arranged on the other side of the spiral conveying mechanism. The third plate is higher than the spiral conveying mechanism to ensure that floating objects enter the spiral conveying mechanism. The third plate 6 and the first scraper are respectively placed on both sides of the spiral conveying mechanism, and the third plate is connected to the second scraper as a whole. The upper side of the third plate 6 can be arranged vertically, or inclined outwardly relative to the vertical side of the shell. The bottom side of the third plate 6 is bent, and the bottom side of the second scraper is also bent. The sides of the third plate and the second scraper are respectively fixed to the shell, so that the upper side of the spiral conveying mechanism and the side facing the roller brush are open, and the bottom is closed, that is, a debris groove is formed by the third plate and the second scraper.

[0047] It is easy to understand that the bottom side of the spiral conveying mechanism is arranged lower than the lower roller brush, and the central axis of the rotating shaft in the spiral conveying mechanism may be slightly lower than the central axis of the lower roller brush.

[0048] In addition, in order to realize the delivery of floating objects, i.e., debris, a debris outlet 1-1 is provided on one side of the spiral conveying mechanism of the shell 1. The debris outlet 1-1 is provided higher than the bottom side of the second scraper. The debris outlet is communicated with the debris trough. A debris bucket can be provided at the debris outlet for centralized treatment of the debris.

[0049] In some examples, the top side of the shell can be open to facilitate observation by staff; in other examples, an openable cover is provided on the top side of the shell. After opening the cover, the working status of the upper roller brush and the lower roller brush can be observed. If there are a lot of floating objects on the two roller brushes, it can also assist in cleaning.

[0050] It can be understood that the first scraper 5-1 and the second scraper 5-2 are located on the inner side of the shell, and naturally the length of the two scrapers is less than or equal to the length of the inner side of the shell. A row of scraping teeth (i.e., including multiple continuous scraping teeth) are arranged at one end of the first scraper and the second scraper close to the roller brush. The spacing between two adjacent scraping teeth 5-3 can be 1 mm or other values. The scraping teeth can be placed between two adjacent circles of stainless steel wire. The arrangement of the scraping teeth facilitates the first scraper and the second scraper to scrape off floating objects (such as plastics, fabrics, etc.) from the roller brush.

[0051] It can be understood that the shell 1 supports the power source, and the power source 8 is specifically a rotating motor, which is fixed to the outside of the shell. The rotating shaft of the rotating motor is connected to the input end of the transmission component, and the output end of the transmission component is connected to the roller brush through a gear transmission mechanism. Therefore, there is no need to set up multiple power sources, and only one power source is needed to realize the movement of multiple components.

[0052] Specifically, the output end of the screw conveying mechanism rotating shaft beyond the housing is connected to the first gear 7-1 in the gear transmission mechanism 7, Figure 1 As shown, the first gear is meshed with the second gear 7-2, the second gear is meshed with the third gear 7-3, the third gear is meshed with the fourth gear 7-4, the second gear is fixed to the lower roller brush rotating roller, the third gear is rotatably mounted on the shell, and the fourth gear is fixed to the upper roller brush rotating roller.

[0053] Considering that there are many components arranged in the separation liquid tank, which need to occupy a certain space, the width of the filtrate tank is smaller than the width of the separation liquid tank.

[0054] Among them, it can be understood that the card slot set at the top of the partition plate 2 is V-shaped, so that a triangular weir structure 2-1 is formed at the top of the partition plate, and a guide plate 2-2 is set on the side of the partition plate facing the roller brush. The setting position of the guide plate is lower than the bottom end of the card slot, and the guide plate and the partition plate are set vertically. The guide plate 2-2 is set higher than the central axis of the upper roller brush 3-1, and the plane where the guide plate is located is tangent to the circle where the stainless steel wire of the upper roller brush is located, so that the overflow filtrate directly flows onto the upper roller brush, which is beneficial to the removal of impurities and flow efficiency of the filtrate. The width of the guide plate is smaller than the distance between the central axis of the roller brush and the partition plate. The setting of the triangular weir structure at the top of the partition plate is beneficial to the liquid in the filtrate tank flowing to the roller brush. The setting of the guide plate is beneficial to leaving floating objects on the upper side of the roller brush and facilitating the floating objects to enter the conveying component.

[0055] The separation device provided in this embodiment has a partition plate arranged in the shell, one side of the partition plate is a filtrate tank, and the other side is a separation liquid tank. When the filtrate in the filtrate tank exceeds the top of the partition plate in height, it flows to the roller brush through the slot at the top of the partition plate, so that floating objects in the filtrate are left on the roller brush. The roller brush can rotate. During the rotation of the roller brush, due to the restriction of the scraper, the floating objects enter the conveying component along the scraper, and the floating objects can be sent out through the conveying component.

[0056] Embodiment 2

[0057] This embodiment provides a kitchen waste treatment device, including a filtrate floating matter separation device as described in the first embodiment.

[0058] In the present embodiment, a food waste treatment device is provided, and a filtrate floating matter separation device can be applied to the entire treatment device to effectively remove floating matter from the filtrate by treating the filtered filtrate, thereby improving the food waste treatment efficiency and treatment effect.

[0059] Embodiment 3

[0060] This embodiment provides a method for separating floating matter from filtrate, using a filtrate floating matter separation device described in Embodiment 1, including the following contents:

[0061] Pour the filtrate with floating objects into the filtrate tank of the shell;

[0062] As the height of the filtrate tank increases, the filtrate reaches the top of the partition plate;

[0063] As the filtrate gradually flows through the card slot to the separation liquid tank, the floating objects in the filtrate fall onto the upper roller brush and the lower roller brush;

[0064] The upper roller brush and the lower roller brush rotate toward the first scraper and the second scraper. Under the restriction of the first scraper and the second scraper, the floating objects fall on the first scraper and the second scraper, and enter the spiral conveying mechanism under the action of inertia and gravity.

[0065] The screw conveying mechanism works to convey the floating objects to the outside of the shell.

[0066] Of course, it is easy to understand that after a long period of actual use, the upper and lower roller brushes may need to be cleaned, but there is no need to stop the machine for cleaning as in the prior art, and a rough cleaning from the top side of the shell is sufficient.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
