Description

Technical Field

[0001] The utility model relates to the technical field of separation treatment, and particularly relates to a device for solid-liquid separation and oil-water separation treatment of catering swill. Background Art

[0002] Catering swill is kitchen waste, including vegetable leaves, leftovers, rice, fruit peels, eggshells, tea dregs, bones, etc. It mainly comes from restaurants, canteens, family kitchens, etc. After proper treatment and processing, catering swill can be transformed into new resources. Its characteristic of high organic matter content enables it to be used as fertilizer and feed after strict treatment. The oil part can be used to prepare biofuels. In daily life, catering swill is mostly directly discharged after filtration. Solid waste and liquid waste cannot be fully separated. At the same time, the direct discharge of the oil-water mixture in liquid waste will cause environmental pollution.

[0003] The prior art discloses a kitchen waste treatment device capable of oil-water separation (publication number: CN113477682A, publication date: October 8, 2021), which includes a crushing cylinder. A crushing blade is installed inside the crushing cylinder. The bottom of the crushing cylinder is fixedly connected with a filtering box. One side of the filtering box is detachably connected with a storage box. A first filter plate is horizontally installed in the middle of the filtering box. An extrusion device is also installed inside the filtering box. A filter oil tank is arranged below the filtering box. The bottom of the filtering box is communicated with the filter oil tank through an oil outlet pipe. A water storage bucket is arranged on one side of the filter oil tank. The water storage bucket is communicated with the filter oil tank through a liquid outlet pipe. A flow outlet is opened on the water storage bucket. By setting the crushing blade, water pump and storage box, this device can break the kitchen waste while leaving the kitchen waste on the first filter plate through the first filter plate for preliminary filtration and storing the filter residue separately for convenient recycling. This kitchen waste treatment device does not consider the situation where solidified oil cannot be separated through the filter plate. At the same time, the working principle during oil-water separation is a communicating vessel. When the liquid waste is less, it cannot be discharged in time. The long-term accumulation of oil and water will cause an increase in odor and the growth of bacteria. Content of the Utility Model

[0004] In view of the technical defects in the background art, the utility model provides a device for solid-liquid separation and oil-water separation treatment of catering swill, which solves the above technical problems and meets the actual needs. The specific technical solutions are as follows:

Specific Embodiments

[0025] The following describes the embodiments of the utility model in conjunction with the drawings and related embodiments. The embodiments of the utility model are not limited to the following examples, and the related necessary components of the utility model in the technical field should be regarded as well-known technologies in the technical field and can be known and mastered by those skilled in the technical field.

[0026] A device for separating solid and liquid and oil and water from catering swill, such as Figure 1 、 2As shown in the figure, it includes an outer shell barrel 1 and a sealing cover 2. The sealing cover 2 is provided at the top of the outer shell barrel 1. Inside the outer shell barrel 1, there are a filtering chamber 4 and a separation chamber 5. The filtering chamber 4 is located above the separation chamber 5. The size of the sealing cover 2 matches the size of the opening at the top of the outer shell barrel 1.

[0027] On one side of the outer shell barrel 1, there is a power socket. Connect the external power supply to the device through the power socket. After pouring the catering swill into the outer shell barrel 1, place the sealing cover 2 on the top of the outer shell barrel 1 to isolate the inside of the device from the outside. Turn on the power switch 3 to start the device, so that the catering swill undergoes solid-liquid separation through the filtering chamber 4. The solid waste remains in the filtering chamber 4, while the filtered oil-water mixture flows into the separation chamber 5, and the oil-water separation is achieved in the separation chamber 5.

[0028] As Figure 3 shown in the figure, the filtering chamber 4 includes a vibrating filter barrel 41, a vibrating motor 42, a spring 43, a heat treatment device 44 and a partition board 45. The vibrating filter barrel 41 is provided with a number of filter holes 6. The vibrating motor 42 is located on the side of the vibrating filter barrel 41. The vibrating filter barrel 41 is elastically connected to the output end of the vibrating motor 42 through the spring 43. The heat treatment device 44 is located above the vibrating filter barrel 41. Both vibrating motors 42 and the heat treatment device 44 are electrically connected to the power switch 3.

[0029] After turning on the power switch 3, the vibrating motor 42 makes the vibrating filter barrel 41 vibrate through the spring 43, and the heat treatment device 44 raises the temperature of the vibrating filter barrel 41. When the catering swill is in the vibrating filter barrel 41 in the filtering chamber 4, part of the oil-water mixture directly flows into the separation chamber 5 through the filter holes 6 on the vibrating filter barrel 41. When more solid waste blocks the filter holes 6, the vibration of the vibrating filter barrel 41 can make the solid waste vibrate accordingly, so that the solid waste is briefly separated from the vibrating filter barrel 41 during vibration, and the liquid oil-water mixture can flow out smoothly from the filter holes 6. In the catering swill, due to the decrease in temperature, part of the grease solidifies to form solid grease. By raising the temperature through the heat treatment device 44, the solid grease melts and the liquid grease is prevented from solidifying, and it flows out with the vibration of the vibrating filter barrel 41, so that the solid waste and the liquid waste can be fully separated.

[0030] The vibrating motor 43 includes two motors with opposite rotation directions of the rotating shafts, and an eccentric block located at the output end of the motor. The motor drives the rotation of the eccentric block. Since the center of gravity of the eccentric block is not on the rotation axis, a centrifugal force will be generated during the rotation process. This centrifugal force will act on the vibrating filter barrel 41 to make it vibrate. At the same time, the two motors with opposite rotation directions of the rotating shafts will make the vibrating filter barrel 41 vibrate up and down. The spring 43, as a buffer device, can effectively reduce the vibration amplitude and frequency generated by the vibrating filter barrel 41 during operation, thereby reducing the impact and damage to the equipment.

[0031] The vibration filter barrel 41 is connected to a vibration motor 42 through a spring. The vibration energy of the vibration motor 42 is transmitted to one end of the vibration filter barrel 41 through the spring 43, so that the vibration filter barrel 41 starts to vibrate. When a large amount of solid waste blocks the filter hole 6, the vibration of the vibration filter barrel 41 can make the solid waste vibrate accordingly, so that the solid waste is temporarily separated from the vibration filter barrel 41 during the vibration, so that the liquid oil-water mixture can flow out of the filter hole 6 smoothly.

[0032] Two vibration motors 42 are provided to be connected to the vibration filter barrel, so that the force component of the vibration filter barrel 41 in the horizontal direction is relatively small, thereby improving the stability of the vibration filter barrel 41 during vibration, thereby improving the efficiency of the liquid oil-water mixture flowing out of the filter hole 6.

[0033] A plurality of heat treatment devices 44 are arranged on the top of the vibration filter barrel 41. The heat treatment devices 44 can be set as electric heaters, which use the heat generated by the current passing through the resistance wire to achieve heating, and the temperature is controlled at 30-40°C. The vibration filter barrel 41 is made of stainless steel material, which can enable the vibration filter barrel 41 to withstand the pressure of restaurant swill. At the same time, stainless steel has a certain thermal conductivity, and the temperature can be increased by the heat treatment device 44.

[0034] like Figure 4 As shown, the separation chamber 5 includes an oil-water separation barrel 51 and a liquid outlet pipe 52. The oil-water separation barrel 51 is fixedly connected to the outer shell barrel 1. A liquid outlet pipe 52 is provided on one side of the bottom of the barrel wall of the oil-water separation barrel 51. The liquid outlet pipe 52 is provided with a valve 7. A liquid outlet hole 11 is provided on one side of the bottom of the barrel wall of the outer shell barrel 1. The liquid outlet pipe 52 is penetrated in the liquid outlet hole 11, and the liquid outlet hole 11 matches the liquid outlet pipe 52.

[0035] The oil-water mixture flowing out of the filter chamber 4 flows into the oil-water separation barrel 51 in the separation chamber 5. Since the density of oil is less than that of water, after standing for a period of time, the oil will float on the surface of the water to form an oil layer, while the water will remain below the oil to form a water layer. The liquid outlet pipe 52 extends to the external water receiving container through the matching liquid outlet hole 11. The valve 7 is opened to discharge the water through the liquid outlet pipe 52 first. After all the water flows out, the valve 7 is closed to achieve the separation of oil and water. When there is enough oil in the vibration filter barrel 51, the valve 7 is opened again to discharge the oil through the liquid outlet pipe 52.

[0036] The outer shell barrel 1 is made of transparent material, so the oil-water stratification in the oil-water separation barrel 51 can be observed from the outside of the outer shell barrel 1 to determine the position of the oil layer. During the water discharge process, the discharge of water in the oil-water separation barrel 51 can be observed. When the valve 7 is opened to drain water through the liquid outlet pipe 52, when it is observed that the water is about to be drained, the water flow rate can be reduced by rotating the valve 7 until the water is completely discharged and the valve 7 is closed.

[0037] As one of the preferred embodiments of the present utility model, as shown in Figure 3 , 5 , more than two vibration motors 42 are provided, and the more than two vibration motors 42 are evenly distributed on the outer side of the vibration filtering barrel 41. A guiding tube 8 is provided outside the spring 43. The guiding tube 8 includes an inner sleeve 81 and an outer sleeve 82. The inner sleeve 81 is fixedly connected to the vibration filtering barrel 41, and the outer sleeve 82 is fixedly connected to the vibration motor 42. The central axis of the inner sleeve 81 coincides with the central axis of the outer sleeve 82. The inner sleeve 81 is located inside the outer sleeve 82, and the guiding tube 8 is matched with the spring 43.

[0038] By arranging more than two vibration motors 42 evenly distributed on the outer side of the vibration filtering barrel 41, the horizontal component force received by the vibration filtering barrel 41 is relatively small, improving the stability of the vibration filtering barrel 41 during vibration, preventing the situation that one vibration motor 42 causes a large vibration amplitude on one side of the vibration filtering barrel 41, resulting in the accumulation of solid waste on the other side inside the vibration filtering barrel 41, thereby improving the efficiency of the liquid oil-water mixture flowing out of the filtering holes 6; the main function of the guiding tube 8 is to provide a clear movement path for the spring 43. When the spring 43 is placed in the inner sleeve 81 of the guiding tube 8, the movement range of the spring 43 is limited within the outer sleeve 82. Since the guiding tube 8 is vertically installed, the spring 43 can only vibrate in the up and down directions and cannot perform lateral or oblique shaking, thereby improving the stability of the vibration of the vibration filtering barrel 41.

[0039] As one of the preferred embodiments of the present utility model, the filtering chamber 4 further includes an annular isolation plate 45. The isolation plate 45 extends upward along the inner ring edge to contact the vibration filtering barrel 41. The outer ring edge of the isolation plate 45 is fixedly connected to the inner wall of the outer shell barrel 1, and the vibration motor 42 is fixedly connected to the isolation plate 45.

[0040] The function of the isolation plate 45 is to prevent the oil and water splashed out from the vibration filtering barrel 41 from contacting the vibration motor 42 and the heat treatment device 44, thereby causing damage to the vibration motor 42 and the heat treatment device 44 and causing unnecessary losses. At the same time, the isolation plate 45 also plays a role in stabilizing the vibration motor 42 and the vibration filtering barrel 41.

[0041] As one of the preferred embodiments of the present utility model, the diameter of the vibration filtering barrel 41 is smaller than the diameter of the oil-water separation barrel 51, so that the oil-water mixture flowing out of the vibration filtering barrel 41 completely flows into the oil-water separation barrel 51.

[0042] In summary, a solid-liquid separation and oil-water separation treatment device for catering swill of the present utility model comprises an outer shell barrel 1 and a sealing cover 2. A filtering chamber 4 and a separation chamber 5 are arranged inside the outer shell barrel 1. Catering swill is subjected to solid-liquid separation in a vibrating filtering barrel 41 in the filtering chamber 4. When the power switch 3 is turned on, a vibrating motor 42 drives the vibrating filtering barrel 41 to vibrate during the filtering process, which can prevent solid waste from blocking the filtering holes 6 and causing the oil and water to not flow out smoothly. A heat treatment device 44 raises the temperature inside the vibrating filtering barrel 41, which can melt the solid grease and prevent the liquid grease from melting, and the melted grease flows out from the filtering holes 6, enabling the solid waste and the liquid waste to be fully separated and realizing the oil-water separation in the catering swill. The oil-water mixture flows into an oil-water separation barrel 51 in the separation chamber 5 from the filtering holes 6. Since the density of the grease is less than that of the water, the grease forms an oil layer on the surface of the water, while the water remains below the oil to form a water layer. When draining water through the liquid outlet pipe 52 by opening the valve 7, when it is observed that the water is about to be drained completely, the water flow rate is reduced by rotating the valve 7 until the valve 7 is closed after the water is completely drained, realizing the oil-water separation in the catering swill.

[0043] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
