Description

Technical Field

[0001] This utility model relates to the field of kitchen slurry processing technology, and in particular to a kitchen slurry filtration device. Background Technology

[0002] Food waste treatment plants primarily rely on microbial activity to degrade pollutants in their wastewater treatment processes. Carbon sources are crucial nutrients for these microorganisms; insufficient carbon sources result in low organic matter concentrations in the wastewater, hindering microbial growth and reproduction, leading to poor wastewater treatment. To ensure microbial growth and reproduction, an external carbon source is necessary. Currently, the carbon sources added to wastewater treatment plants are mainly sugars, oils, organic acids, alcohols, and hydrocarbons, all of which must be purchased externally, resulting in high costs. Some food waste treatment plants on the market use vibrating screens to sift food slurry to obtain carbon sources. However, these vibrating screens operate at high frequencies, have unstable structures, and are prone to leakage and wear at joints, easily polluting the surrounding environment and causing unnecessary waste. Utility Model Content

[0003] The purpose of this utility model is to provide a kitchen slurry filtration device, in which the vibrator and the shell are set independently, which can avoid problems such as easy leakage and wear at the joints, and improve cleanliness and slurry recycling rate.

[0004] To achieve this objective, the present invention adopts the following technical solution: a kitchen slurry filtration device, comprising a frame and a vibrating screen assembly. The frame includes a housing and support legs, the support legs being supported below the housing. The housing has a sealed inner cavity and an inlet, an outlet, and a slag discharge port communicating with the inner cavity. The vibrating screen assembly is installed in the inner cavity and spaced apart from the inner wall of the housing. The vibrating screen assembly includes a vibrating motor, a vibrating body, and a screen. The screen is installed on the vibrating body. The top of the support legs has an extension portion that extends into the housing and is elastically connected to the vibrating body via a spring. The screen is inclined between the inlet and the slag discharge port. The vibrating body has a bucket-shaped discharge port. The screen, the discharge port, and the outlet are arranged sequentially from top to bottom in the vertical direction.

[0005] Preferably, a water distributor is provided between the feed inlet and the screen. The water distributor is provided with a buffer trough and a dike. The buffer trough is located below the feed inlet, and the dike is arranged around the buffer trough. The side of the dike facing the screen has a hollow structure for the flow of kitchen slurry.

[0006] Preferably, the housing is provided with a flushing pipe interface communicating with the inner cavity, the flushing pipe interface being located on one side of the feed inlet and above the water distributor.

[0007] Preferably, the support leg is provided with a mounting bracket, and the mounting bracket is equipped with a foot cup.

[0008] Preferably, the screen is provided in multiple ways, and the multiple screens are spaced apart along the height direction of the vibrator and detachably connected to the vibrator.

[0009] Preferably, along the height direction of the vibrating body, the mesh count of the plurality of screens increases sequentially from top to bottom.

[0010] Preferably, the housing is provided with a deodorizing port, which is located above the screen and communicates with the inner cavity.

[0011] Preferably, the outer edges of the deodorization port, the feed port, the discharge port, and the slag discharge port are all provided with connecting flanges.

[0012] Preferably, the vibrator has a sloping surface on the side near the slag discharge port, and the sloping surface is located between the screen and the slag discharge port.

[0013] Preferably, a cooling fan is installed inside the housing, with the air inlet of the cooling fan facing the vibration motor.

[0014] The beneficial effects of this invention are as follows: After the kitchen slurry enters the shell through the inlet, it falls onto an inclined screen. The vibrating motor drives the screen to vibrate, thereby separating the waste and impurities from the slurry, allowing the remaining slurry to be used directly as a carbon source. The separated slurry flows out of the shell through the discharge port and outlet, while the separated waste and impurities flow out of the shell through the slag discharge port under gravity, facilitating user recycling. The vibrating screen assembly is installed inside the cavity and spaced apart from the inner wall of the shell. The support legs extend into the body and are elastically connected to the vibrating body through springs. Without affecting the vibration of the vibrating body, the vibrating body and the shell are arranged independently. This ensures that the shell remains stationary during operation, unaffected by the vibrating body, solving problems such as leakage and wear at the joints of vibrating equipment. This effectively improves the structural stability of the filtration device. Furthermore, the kitchen slurry is filtered within a sealed inner cavity, further preventing leakage and improving the cleanliness and slurry recycling rate of the filtration device.

[0028] Reference Figures 1 to 5 As shown, a kitchen slurry filtration device according to an embodiment of this application includes a frame 100 and a vibrating screen assembly 200. The frame 100 includes a housing 110 and support legs 120. Multiple support legs 120 are provided and arranged in a matrix. The support legs 120 are supported below the housing 110. The housing 110 is provided with a sealed inner cavity 111 and an inlet 112, an outlet 113 and a slag discharge port 114 communicating with the inner cavity 111.

[0029] The vibrating screen assembly 200 is installed inside the inner cavity 111 and spaced apart from the inner wall of the housing 110. The vibrating screen assembly 200 includes a vibrating motor 210, a vibrating body 220, and a screen 230. The screen 230 is installed on the vibrating body 220. The top of the support leg 120 is provided with an extension part 121, which extends into the housing 110 and is elastically connected to the vibrating body 220 through a spring 123. The screen 230 is inclined between the feed inlet 112 and the slag discharge outlet 114. Specifically, in the horizontal direction, the end of the screen 230 near the slag discharge outlet 114 is inclined downwards. The vibrating body 220 is provided with a bucket-shaped discharge outlet 221. The screen 230, the discharge outlet 221, and the discharge outlet 113 are arranged sequentially from top to bottom in the vertical direction. The inclined screen 230 can maintain tension, making it easier for the slurry to move on the screen 230.

[0030] Understandably, after the kitchen waste slurry enters the housing 110 through the inlet, it falls onto the inclined screen 230. The vibrating motor 210 drives the screen 230 to vibrate, thereby separating the waste and impurities from the kitchen waste slurry, allowing the remaining kitchen waste slurry to be used directly as a carbon source. The separated kitchen waste slurry flows out of the housing 110 through the discharge port 221 and the outlet 113, while the separated waste and impurities flow out of the housing 110 through the slag discharge port 114 under the action of gravity, facilitating recycling by users.

[0031] The vibrating screen assembly 200 is installed inside the inner cavity 111 and spaced apart from the inner wall of the housing 110. Support legs 120 extend into the body and are elastically connected to the vibrating body 220 via springs 123. Without affecting the vibration of the vibrating body 220, the vibrating body 220 and the housing 110 are arranged independently. This ensures that the housing 110 remains stationary during operation, unaffected by the vibrating body 220, thus solving problems such as leakage and wear at the joints of vibrating equipment. This effectively improves the structural stability of the filtration device. Furthermore, since the kitchen slurry is filtered within the sealed inner cavity 111, leakage is further prevented, avoiding liquid spillage and improving the cleanliness and slurry recovery rate of the filtration device. In addition, the discharge port 113 and the slag discharge port 114 work together to allow the filtration device to simultaneously drain water and discharge slag. The vibrating body 220 can vibrate at high speed without affecting the stability of the housing 110, significantly increasing the filtration speed and throughput of the filtration device. The filtered slurry has fewer impurities and a high retention rate of alcohols and hydrocarbons, ensuring the quality of the carbon source after filtration.

[0032] It should be noted that the vibrator 220 is equipped with an adjustable vibrating block. The vibration frequency and amplitude of the vibrator 220 can be adjusted by adjusting the vibrating block on the vibrator 220, which will not be elaborated here.

[0033] Reference Figure 1 As shown, it can be understood that the outrigger 120 is equipped with a mounting bracket, which is welded and fixed to the outrigger 120. The mounting bracket is equipped with a foot cup 122. Since the foot cup 122 is a mature technology and there are many models to choose from, the structure of the foot cup 122 will not be described in detail here.

[0034] By installing foot cups 122 on the support legs 120, users can adjust the height of the foot cups 122, thereby adjusting the height of one side of the housing 110, and thus changing the tilt angle of the screen 230 to adapt to different kitchen slurries, effectively improving the practicality of the filtration device. For example, if the kitchen slurry has a high water content and low viscosity, the tilt angle of the screen 230 can be reduced to prolong the residence time of the slurry on the screen 230, ensuring filtration efficiency; if the kitchen slurry has a high solid content and high viscosity, the tilt angle of the screen 230 can be increased to reduce friction on the screen 230, ensuring filtration efficiency.

[0035] Reference Figure 2 and Figure 3As shown, it can be understood that a water distributor 300 is provided between the feed inlet 112 and the screen 230. The water distributor 300 is provided with a buffer trough 310 and a dike 320. The buffer trough 310 is located below the feed inlet 112, and the dike 320 is arranged around the buffer trough 310. The side of the dike 320 facing the screen 230 has a perforated structure for the flow of kitchen slurry. Optionally, the perforated structure can be multiple waist-shaped holes, multiple round holes, or a mesh structure opened on the side wall of the dike 320, which will not be described in detail here.

[0036] After the kitchen slurry enters the housing 110 through the inlet 112, it first falls into the buffer tank 310, then accumulates and overflows into the weir 320. After the weir 320 is connected to a baffle plate, the kitchen slurry in the weir 320 passes through the perforated structure and flows out of the weir 320, ensuring the slurry is evenly distributed and flows out to the screen 230. By setting up the buffer tank 310 and the weir 320 with a perforated structure, the kitchen slurry can be buffered and spread evenly onto the screen 230, ensuring the uniformity of the kitchen slurry on the screen 230 and effectively enhancing the filtration effect of the screen 230.

[0037] Reference Figure 1 and Figure 2 As shown, it can be understood that the housing 110 is provided with a flushing pipe interface 115 that communicates with the inner cavity 111. The flushing pipe interface 115 is located on one side of the feed inlet 112 and above the water distributor 300. The flushing pipe interface 115 is connected to a flushing device.

[0038] By setting the flushing pipe interface 115, the user can start the flushing device before and after using the filter device, so that the high-pressure water flow can be used to flush the water distributor 300, screen 230 and vibrator 220 through the flushing pipe interface 115. The flushed wastewater is discharged through the discharge port 113 and the slag discharge port 114, automatically cleaning the slag on the screen 230, achieving the purpose of preventing blockage and cleaning slag, and ensuring the cleanliness of the internal devices of the housing 110, avoiding contamination of kitchen slurry.

[0039] Furthermore, the housing 110 is provided with a deodorizing port 116, which is located above the screen 230 and communicates with the inner cavity 111. The deodorizing port 116 is connected to a deodorizing device.

[0040] By setting up the deodorization port 116, the deodorization equipment in the workshop removes the odor from the slurry when the filter is working, reducing the impact of the odor on the environment and workers, and effectively improving the safety and environmental friendliness of the filter.

[0041] Reference Figure 2 and Figure 4As shown, it can be understood that multiple screens 230 are provided, and the multiple screens 230 are spaced apart along the height direction of the vibrator 220 and detachably connected to the vibrator 220. Optionally, the screens 230 can be detachably connected to the inner walls of both sides of the vibrator 220 by means of angle iron bolt structure, slot structure, locking structure, etc., which will not be described in detail here.

[0042] By setting a detachable and washable screen 230, on the one hand, users can set a screen 230 with an appropriate mesh size according to the particle size of the medium and the amount of slag and impurities, thereby controlling the particle size of the finished carbon source and effectively improving the controllability of the filtration device; on the other hand, the screen 230 is integrated into the vibrator 220, which is set in a sealed inner cavity 111, which can simplify the structure of the filtration device, improve the integration of the filtration device, and reduce the number of devices, installation space and floor area.

[0043] It should be noted that multiple screens 230 are located above the slag discharge port 114 and are inclined toward the slag discharge port 114 to ensure that the filtered impurities can be discharged from the shell 110 through the slag discharge port 114.

[0044] Furthermore, along the height direction of the vibrating body 220, the mesh count of the multiple screens 230 increases sequentially from top to bottom.

[0045] By decreasing the mesh size of multiple screens 230 from top to bottom, the cooperation of multiple screens 230 can achieve step-by-step screening of kitchen slurry, so that impurity particles with larger outer diameters are filtered out first, and substances that can serve as carbon sources can be screened out in the end, further ensuring the quality of carbon sources.

[0046] Reference Figure 4 As shown, it can be understood that the vibrator 220 has a ramp 222 on the side near the slag discharge port 114. In the horizontal direction, the end of the ramp 222 near the slag discharge port 114 slopes downward, and the inclination of the ramp 222 is greater than or equal to the inclination of the screen 230. The ramp 222 is located between the screen 230 and the slag discharge port 114.

[0047] By setting the inclined surface 222, on the one hand, the inclined surface 222 can fill the gap between the screen 230 and the slag discharge port 114, preventing the filtered impurities from accumulating on the surface of the vibrator 220 below the screen 230, which would affect the vibration of the vibrator 220 and contaminate the internal space of the shell 110; on the other hand, the inclined surface 222 can guide the filtered impurities to flow quickly to the slag discharge port 114, further improving the working efficiency of the filtration device.

[0048] Reference Figure 1 and Figure 5 As shown, it can be understood that the outer edges of the deodorization port 116, the feed port 112, the discharge port 113, and the slag discharge port 114 are all provided with connecting flanges.

[0049] By pre-installing connecting flanges at the deodorization port 116, feed port 112, discharge port 113, and slag discharge port 114, the filter device can be easily connected to external deodorization devices, flushing devices, feeding devices, receiving devices, and waste recycling devices, thereby improving the ease of use of the filter device.

[0050] Furthermore, the housing 110 includes a frame and multiple quick-release sealing plates 130. The frame and the multiple sealing plates 130 enclose a sealed inner cavity 111. The deodorization port 116, the feed port 112, the discharge port 113, and the slag discharge port 114 are respectively located on different sealing plates 130. Optionally, the sealing plates 130 can be detachably connected to the frame by bolts, latches, flanges, or other structures, which will not be described in detail here. The sealing plate 130 located above the slag discharge port 114 is also provided with an observation port 117 for the user to observe the slag discharge situation.

[0051] By incorporating a quick-release sealing plate 130, users can easily replace the filter screen 230 or remove the vibrator 220 entirely from the top for inspection and maintenance, reducing the later maintenance costs of the filtration device. Furthermore, users can configure deodorization ports 116, feed ports 112, discharge ports 113, and slag discharge ports 114 with different apertures according to actual needs, thereby adjusting the filtration device's processing capacity, drainage capacity, and slag discharge capacity, further improving the practicality of the filtration device.

[0052] Reference Figure 2 and Figure 5 As shown, it can be understood that a cooling fan 240 is installed inside the housing 110. The air inlet of the cooling fan 240 is set towards the vibration motor 210. The cooling fan 240 is installed on one side of one of the sealing plates 130, and the sealing plate 130 corresponding to the cooling fan 240 is provided with a grid structure for airflow to pass through.

[0053] By setting up a cooling fan 240, when the filter device is working, the cooling fan 240 can quickly remove the heat generated by the vibration motor 210, effectively extending the service life of the vibration motor 210.

[0054] 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.
