Description

Technical Field

[0001] This invention relates to the field of food waste treatment technology, and in particular to a filtrate floating matter separation device, food waste treatment equipment and method. Background Technology

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

[0003] The current challenge and key focus of food waste pretreatment is how to separate inorganic impurities from the waste as much as possible. Food waste has a high inorganic content, which can be divided into light and heavy impurities. If light impurities (such as plastics and textiles) are not removed, they will form a thick scum cover in the subsequent post-treatment tank, preventing gas from escaping and posing a safety hazard. Therefore, removing floating matter from the food waste filtrate is essential.

[0004] In the existing technology, the equipment for removing impurities from kitchen waste includes sand-water separators, which mainly remove floating objects through a filter screen. However, because of the mesh of the filter screen, floating objects can easily clog it. If the filter screen is not cleaned, the subsequent treatment quality of floating objects will be poor and the treatment efficiency will be low. If the filter screen is cleaned, the machine needs to be stopped, which will delay the processing work of the equipment and affect the normal use of the entire device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a filtrate floating matter separation device that effectively separates light inorganic impurities from the filtrate, with high cleaning efficiency and good floating matter treatment effect.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0007] A filtrate floating matter separation device includes a housing, with a partition plate inside the housing such that one side of the partition plate is a filtrate tank and the other side is a separation liquid tank. The top of the partition plate is set below the top of the housing, and multiple slots are provided on the top of the partition plate. A roller brush is installed in the separation liquid tank below the slots, and the roller brush is rotatable relative to the housing. A conveying component is installed in the separation liquid tank below the roller brush, and a scraper is installed between the conveying component and the roller brush. One end of the scraper contacts the roller brush. As the filtrate in the filtrate tank flows through the slots to the separation liquid tank, the floating matter in the filtrate falls onto the roller brush. During the rotation of the roller brush, the floating matter enters the conveying component under the action of the scraper.

[0008] As described above, the separation device has a partition plate inside the housing. 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, it flows to the roller brush through the slot at the top of the partition plate, so that the floating matter in the filtrate is 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 matter enters the conveying component along the scraper. The conveying component can send the floating matter out.

[0009] As described above, the filtrate floating matter separation device has two roller brushes. Along the height direction of the housing, two roller brushes are arranged vertically. Both roller brushes can rotate in the direction of the conveying component. The upper roller brush and the lower roller brush are spaced apart. The upper roller brush plays the role of primary filtration, and the lower roller brush plays the role of secondary filtration to remove the impurities left by the upper roller brush.

[0010] The scraper is positioned so that one end near the roller brush is higher than the other end, allowing the floating material to flow towards the conveying component under the influence of inertia and gravity.

[0011] As described above, the filtrate floating matter separation device has two scraper locations: a first scraper and a second scraper. One end of the first scraper is inserted into the bristles of the upper roller brush, and the other end of the first scraper is connected to the middle of the conveying component. The other end of the second scraper is inserted into the bristles of the lower roller brush, and the other end of the second scraper is connected to the bottom side of the conveying component. The first scraper and the upper roller brush are aligned, and the second scraper and the lower roller brush are aligned, so that the floating matter falling at the two roller brush locations is moved to the conveying component by the first scraper or the second scraper.

[0012] As described above, in a filtrate floating matter separation device, the conveying component is a spiral conveying mechanism. The spiral conveying mechanism is rotatable relative to the housing. A first scraper and a second scraper are provided on one side of the spiral conveying mechanism, and a third plate is provided on the other side of the spiral conveying mechanism. The third plate is set higher than the spiral conveying mechanism to ensure that the floating matter enters the spiral conveying mechanism. The third plate is connected to the second scraper as a whole. The third plate and the first scraper are respectively placed on both sides of the spiral conveying mechanism, so that the upper side and the side facing the roller brush of the spiral conveying mechanism are open, and the bottom is closed.

[0013] In the filtrate floating matter separation device described above, the length of the scraper is less than or equal to the length of the inner side of the housing;

[0014] A row of scraping teeth is provided on the side of the scraper near the roller brush. The arrangement of the scraping teeth facilitates the rapid removal of floating objects at the roller brush.

[0015] As described above, in a filtrate floating matter separation device, the housing supports a power source, the power source is connected to the input end of the conveying component, and the output end of the conveying component is connected to the roller brush through a gear transmission mechanism. Thus, there is no need to set up multiple power sources; only one power source is needed to realize the movement of multiple components.

[0016] As described above, in a filtrate floating matter separation device, considering that there are many components installed in the separation tank and a certain amount of space is required, the width of the filtrate tank is smaller than the width of the separation tank.

[0017] As described above, in a filtrate floating matter separation device, the slot at the top of the partition plate is V-shaped, thus forming a triangular weir structure at the top of the partition plate. A guide plate is provided on the side of the partition plate facing the roller brush, and the guide plate is positioned above the central axis of the upper roller brush. The width of the guide plate is less than the distance between the central axis of the roller brush and the partition plate. The triangular weir structure at the top of the partition plate facilitates the flow of liquid in the filtrate tank towards the roller brush, and the guide plate helps to retain floating matter on the upper side of the roller brush, facilitating the entry of floating matter into the conveying component.

[0018] Secondly, the present invention provides a kitchen waste treatment device, including the aforementioned filtrate floating matter separation device.

[0019] Thirdly, the present invention provides a method for separating floating matter in a filtrate, employing the aforementioned filtrate floating matter separation device, comprising the following:

[0020] Pour the filtrate containing floating matter into the filtrate tank of the shell;

[0021] As the height of the filtrate tank increases, the filtrate reaches the top of the partition plate;

[0022] As the filtrate flows gradually from the slot to the separation tank, the floating matter in the filtrate falls onto the roller brush.

[0023] The roller brush rotates in the direction of the scraper, and under the constraint of the scraper, the floating objects pass through the scraper and enter the conveying component;

[0024] The conveying component works to transfer the floating object to the outside of the shell.

[0025] The beneficial effects of the present invention are as follows:

[0026] 1) This invention includes a separation device with a partition plate inside the housing. 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, it flows to the roller brush through the slot at the top of the partition plate, leaving the floating matter in the filtrate on the roller brush. The roller brush can rotate, and during its rotation, the floating matter is restricted by the scraper and enters the conveying component along the scraper. The conveying component can then send the floating matter out. The entire process utilizes the lightness of the scum and gravity to remove impurities, resulting in low energy consumption. It avoids the problem of clogging the filter screen in the prior art and can achieve rapid and efficient removal of floating matter.

[0027] 2) This invention uses two roller brushes in the middle. The upper roller brush plays a primary filtration role, while the lower roller brush plays a secondary filtration role, filtering out the impurities left by the upper roller brush and ensuring the efficiency of removing impurities from floating objects.

[0028] 3) In this invention, the first scraper and the second scraper are reasonably arranged. One end of the two scrapers is inserted into the side of the corresponding roller brush, and the other side of the two scrapers is connected to the conveying component. The scraper is equipped with scraping teeth to facilitate the rapid removal of floating objects at the roller brush. A third plate is provided on the other side of the conveying component. The third plate and the first scraper are respectively placed on both sides of the spiral conveying mechanism, so that the upper side and the side facing the roller brush of the spiral conveying mechanism are open, and the bottom is closed.

[0029] 4) The present invention is equipped with a triangular weir structure. The flow control of the triangular weir has a high removal efficiency and facilitates the uniform flow of filtrate to the roller brush. The reasonable arrangement of the guide plate structure is conducive to the direct flow of filtrate to the roller brush, which is beneficial to the removal of impurities from the filtrate and ensures the flow efficiency of the filtrate.

[0030] 5) The present invention provides a kitchen waste treatment device, wherein the filtrate floating matter separation device can be applied to the entire treatment device to treat the filtered filtrate, effectively remove the floating matter in the filtrate, and improve the efficiency and effect of kitchen waste treatment.

As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form.

[0039] As described in the background section, existing technologies suffer from problems such as difficulty in removing floating matter from filtrate and low removal efficiency. To address these technical issues, this invention proposes a filtrate floating matter separation device.

[0040] Example 1

[0041] In a typical embodiment of the present invention, reference is made to Figure 1 , Figure 2As shown, a filtrate floating matter separation device includes a housing 1, with an internal space. A partition plate 2 is installed inside the housing 1, such that one side of the partition plate is a filtrate tank and the other side is a separation tank. The partition plate is perpendicular to the bottom plate of the housing. The top of the partition plate 1 is set below the top of the housing to prevent the filtrate from exceeding the top of the housing. Multiple slots are provided at the top of the partition plate. A roller brush 3 is installed in the separation tank of the housing 1 at a position below the slots. The roller brush is rotatable relative to the housing. A conveying component 4 is installed in the separation tank of the housing at a position below the roller brush. A scraper 5 is installed between the conveying component and the roller brush. One end of the scraper 5 contacts the roller brush 3. As the filtrate in the filtrate tank flows to the separation tank through the slots, the floating matter in the filtrate falls onto the roller brush. During the rotation of the roller brush, the floating matter enters the conveying component under the action of the scraper.

[0042] In this embodiment, the roller brush 3 is provided in two locations, along the height direction of the housing, as referenced. Figure 3 As shown, there are two roller brushes, one above the other. Both roller brushes can rotate in the direction of the conveying component. The upper roller brush 3-1 and the lower roller brush 3-2 are spaced apart. The upper roller brush plays a primary filtering role, while the lower roller brush plays a secondary filtering role, filtering out the impurities left by the upper roller brush.

[0043] Specifically, each of the roller brushes 3 includes a rotating roller with bristles arranged circumferentially. The bristles are multiple turns of stainless steel wire, with a spacing between adjacent turns of stainless steel wire. Each turn has multiple stainless steel wires arranged along the radial direction of the rotating roller, and the length of the stainless steel wires is greater than or equal to 5mm. The stainless steel wires of the upper roller brush and the lower roller brush do not come into contact.

[0044] To cooperate with the corresponding roller brush 3, the natural scraper 5 is provided in two places, 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 upper roller brush across the horizontal plane of the central axis, without contacting the rotating roller of the roller brush. The other end of the first scraper is connected to the middle of the conveying component. 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 on the side of the lower roller brush across the horizontal plane of the central axis. The other end of the second scraper is connected to the bottom side of the conveying component. The first scraper 5-1 and the upper roller brush 3-1 are connected, and the second scraper and the lower roller brush are connected, so that the floating objects falling at the two roller brushes are moved to the conveying component by the first scraper or the second scraper.

[0045] Thus, the end of the first scraper near the upper roller brush is set higher than the other end of the first scraper, and the end of the second scraper near the lower roller brush is set higher than the other end of the second scraper, so that the floating object can flow to the conveying component 4 under the action of inertial force and gravity.

[0046] In this embodiment, the conveying component 4 is a spiral conveying mechanism. The spiral conveying mechanism is rotatable relative to the housing. The housing 1 can support the rotating shaft 4-2 of the spiral conveying mechanism through bearings. The rotating shaft is located on the side of the lower roller brush away from the separator plate. The rotating shaft is circumferentially arranged with spiral blades 4-1. 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 set 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. The third plate and the second scraper are connected as one piece. The upper side of the third plate 6 can be set vertically or tilted outward relative to the vertical side of the housing. The bottom side of the third plate 6 is bent. 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 housing, so that the upper side and the side facing the roller brush of the spiral conveying mechanism are open, and the bottom is closed, that is, the debris groove is formed by the third plate and the second scraper.

[0047] It is easy to understand that the bottom side of the screw conveyor is set lower than the lower roller brush, and the central axis of the rotating shaft in the screw conveyor can be slightly lower than the central axis of the lower roller brush.

[0048] In addition, in order to deliver floating objects or debris, the housing 1 is provided with a debris outlet 1-1 on one side of the screw conveyor mechanism. The debris outlet 1-1 is located above the bottom side of the second scraper. The debris outlet is connected to the debris trough. A debris bucket can be set at the debris outlet for centralized processing of debris.

[0049] In some examples, the top side of the housing can be open to facilitate observation by staff; in other examples, the top side of the housing is equipped with an openable cover. After opening the cover, the working status of the upper and lower roller brushes can be observed, and if there is a lot of floating debris at the two roller brushes, it can also assist in cleaning.

[0050] Understandably, the first scraper 5-1 and the second scraper 5-2 are located inside 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 consecutive scraping teeth) is provided at the end of the first scraper and the second scraper near 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 turns of stainless steel wire. The arrangement of the scraping teeth is conducive to the first scraper and the second scraper scraping away floating objects (such as plastic, fabric, etc.) from the roller brush.

[0051] Understandably, the housing 1 supports the power source, and the power source 8 is specifically a rotary motor. The rotary motor is fixed to the outside of the housing, and the rotating shaft of the rotary motor is connected to the input end of the transmission component. The output end of the transmission component is connected to the roller brush through a gear transmission mechanism. Thus, there is no need to set up multiple power sources. Only one power source is needed to realize the movement of multiple components.

[0052] Specifically, the output end of the rotating shaft of the screw conveyor mechanism, which extends beyond the housing, is connected to the first gear 7-1 in the gear transmission mechanism 7. (Refer to...) Figure 1 As shown, the first gear meshes with the second gear 7-2, the second gear meshes with the third gear 7-3, the third gear meshes with the fourth gear 7-4, the second gear is fixed at the lower rotating brush roller, the third gear is rotatably mounted at the housing, and the fourth gear is fixed at the upper rotating brush roller.

[0053] Considering that there are many components installed in the separation tank, which require a certain amount of space, the width of the filtrate tank is smaller than the width of the separation tank.

[0054] It can be understood that the slot at the top of the partition plate 2 is V-shaped, thus forming a triangular weir structure 2-1 at the top of the partition plate. A guide plate 2-2 is set on the side of the partition plate facing the roller brush. The guide plate is set below the bottom of the slot and is perpendicular to the partition plate. The guide plate 2-2 is set above the central axis of the upper roller brush 3-1, and the plane of the guide plate is tangent to the circle of the stainless steel wire of the upper roller brush. This allows the overflowing filtrate to flow directly onto the upper roller brush, which is beneficial for the removal of impurities and the flow efficiency of the filtrate. The width of the guide plate is less than the distance between the central axis of the roller brush and the partition plate. The triangular weir structure at the top of the partition plate facilitates the flow of liquid in the filtrate tank to the roller brush. The guide plate helps to leave floating objects on the upper side of the roller brush and facilitates the entry of floating objects into the conveying component.

[0055] The separation device provided in this embodiment has a partition plate inside the housing. 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, it flows to the roller brush through the slot at the top of the partition plate, so that the floating matter in the filtrate is 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 matter enters the conveying component along the scraper. The conveying component can send the floating matter out.

[0056] Example 2

[0057] This embodiment provides a kitchen waste treatment device, including a filtrate floating matter separation device as described in Embodiment 1.

[0058] In this embodiment, a food waste treatment device is provided, in which a filtrate floating matter separation device can be applied to the entire treatment device to treat the filtered filtrate, effectively removing floating matter from the filtrate and improving the efficiency and effect of food waste treatment.

[0059] Example 3

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

[0061] Pour the filtrate containing floating matter 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 flows gradually from the slot to the separation tank, the floating matter in the filtrate falls onto the upper and lower roller brushes.

[0064] The upper and lower roller brushes rotate toward the first and second scrapers. Under the constraint of the first and second scrapers, the floating objects fall onto the first and second scrapers and enter the screw conveyor mechanism under the action of inertia and gravity.

[0065] The screw conveyor mechanism works to transport 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 it is not necessary to stop the machine for cleaning as in existing technologies. A rough cleaning can be done from the top side of the housing.

[0067] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
