Description

Technical Field

[0001] The present invention relates to the technical field of kitchen waste treatment, and specifically relates to a gutter oil recovery and treatment device for the kitchen waste field. Background Technique

[0002] Gutter oil generally refers to various inferior oils existing in life, such as recycled edible oil, repeatedly used frying oil, etc. It is a non-edible oil with extremely poor quality and extremely unhygienic. A large amount of gutter oil is contained in kitchen waste, and a gutter oil recovery and treatment device is needed to recover the gutter oil in the kitchen waste.

[0003] The existing recovery and treatment of gutter oil from kitchen waste can only be simply processed. Through a solid-liquid separator, the solid and liquid in the kitchen waste are separated. Then, through an oil-water separator, the filtered oil-water mixture is separated. After the recovered gutter oil is deacidified, decolorized and refined, it can be made into industrial lubricants, mold release agents or feed mixed oil, or after saponification treatment, it can be used to process soap. However, when gutter oil is used in industry, the purity requirement for grease is relatively high, and simple oil-water separation cannot meet the standard of recycling. It is necessary to transport the water-containing gutter oil for further distillation and extraction. Compared with directly transporting gutter oil with higher purity, transporting water-containing gutter oil increases the transportation cost, and at the same time, purification treatment is also required. When used for soap processing, its added value is low and the economic benefit is limited. The existing gutter oil recovery and treatment equipment for kitchen waste cannot recover gutter oil with higher purity, and the components of the recovery equipment are placed separately, resulting in a large floor area and being not suitable for the interior of a kitchen with limited space and inconvenient to use. Therefore, we propose a gutter oil recovery and treatment device for the kitchen waste field to solve the problems raised. Summary of the Invention

[0004] The purpose of the present invention is to provide a gutter oil recovery and treatment device for the kitchen waste field to solve the problems in the current market proposed in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A gutter oil recovery and treatment device for the kitchen waste field, including a box body. Inside the bottom of the box body, a centrifugal filter, an oil-water separator, a heat energy recovery device and a distiller are sequentially installed.

A centrifugal filter cylinder is rotatably connected between the partition plate and the support; The top of the centrifugal filter cylinder is connected to the bottom of the crusher through a feed pipe. The bottom end of the feed pipe is rotatably connected to the centrifugal filter cylinder. When the crushing knife roller rotates, it drives the centrifugal filter cylinder to rotate synchronously through a transmission mechanism.

[0007] Preferably, the first reversing gear and the second reversing gear are respectively meshed with the third reversing gear and the fourth reversing gear, and the outer diameter of the second reversing gear is smaller than the outer diameter of the fourth reversing gear.

[0008] Preferably, the transmission mechanism includes transmission gears. Transmission gears are installed at the shaft ends of the crushing knife roller near the lower part of the crusher. The transmission gears are meshed with each other. An annular gear is installed at the top of the centrifugal filter cylinder. A driving gear is rotatably connected to the inner top of the centrifugal filter near the annular gear. The driving gear and the corresponding transmission gear are fixedly connected through a transmission rod.

[0009] Preferably, the cleaning mechanism includes a slag discharge pipe. The slag discharge pipe is connected to one side of the centrifugal filter near the bottom. A sewage discharge pipe is connected to one side of the centrifugal filter above the partition board. A pipe groove is opened in the middle of the bottom end of the centrifugal filter cylinder. A discharge pipe is installed in the middle of the partition board. The top end of the discharge pipe penetrates through the partition board and the inside of the pipe groove. The discharge pipe is connected to the bottom of the centrifugal filter and forms a rotating connection. A flushing pipe is installed on the inner wall of the centrifugal filter corresponding to the centrifugal filter cylinder. Nozzles are equidistantly installed on one side of the flushing pipe near the centrifugal filter cylinder. A water inlet pipe is connected to the middle of the flushing pipe.

[0010] Preferably, the inner bottom of the centrifugal filter slopes downward toward the slag discharge pipe.

[0011] Preferably, the rotating connection between the centrifugal filter cylinder and the partition board is sealed through a dynamic seal ring. The rotating connection between the centrifugal filter cylinder and the discharge pipe is also sealed through a dynamic seal ring.

[0012] Preferably, a delivery pump is installed inside the box body near the centrifugal filter and the oil-water separator. The delivery pump is communicated with the centrifugal filter on one side above the partition through a suction pipe, and the delivery pump is communicated with the oil-water separator through a delivery pipe.

[0013] Preferably, the heat energy recovery mechanism includes a first communication frame. The first communication frame and the second communication frame are respectively installed inside the upper and lower parts of the heat energy recovery device. The bottom end of the second communication frame is communicated with a second drain pipe. Heat exchange pipes are equidistantly communicated between the first communication frame and the second communication frame. The first communication frame is communicated with the top of the distiller through a steam pipe.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, kitchen waste oil and water are put into the inside of the crusher through the feed hopper. The driving mechanism drives the crushing cutter roller and the stirring rod to rotate simultaneously. The crushing cutter roller crushes the solids in the oil and water, and then enters the centrifugal filter cylinder through the feed pipe. The crushing cutter roller drives the centrifugal filter cylinder to rotate through the transmission mechanism, so that the centrifugal filter cylinder generates centrifugal force to separate the solid and liquid of the oil and water. The filtered oil-water mixture is separated by the oil-water separator. The sewage is discharged through the first drain pipe. The gutter oil enters the inside of the distiller after passing through the heat energy recovery device. The gutter oil is distilled by heating to further remove the moisture in the gutter oil. The purified gutter oil is discharged through the drain pipe. Through this gutter oil recovery and treatment equipment, the gutter oil in the kitchen waste oil and water can be separated, and at the same time, the gutter oil can be purified, saving the subsequent treatment cost of the gutter oil. The gutter oil can be recycled, and the recovery and treatment equipment is highly integrated, reducing the floor area of the recovery and treatment equipment, so as to be suitable for the recovery of kitchen gutter oil.

[0015] In the present invention, when the double-shaft motor works, it drives the first reversing gear and the second reversing gear to rotate simultaneously. The first reversing gear drives the crushing cutter roller to rotate through the meshing with the third reversing gear. At the same time, the second reversing gear drives the stirring rod to rotate through the meshing with the fourth reversing gear. The outer diameter of the second reversing gear is smaller than the outer diameter of the fourth reversing gear, so that the double-shaft motor can drive the crushing cutter roller to rotate at a high speed while driving the stirring rod to rotate at a low speed. Thus, through a single double-shaft motor, the crushing cutter roller can be driven to crush the material and the stirring rod can be driven to stir the distilled gutter oil at the same time, reducing the number of driving motors, and effectively reducing the production cost of the equipment.

[0016] In the present invention, the two crushing cutter rollers 7 can rotate in opposite directions simultaneously through the transmission gear 20. At the same time, the transmission gear 20 drives the driving gear 22 to rotate through the transmission rod 23. The driving gear 22 drives the centrifugal filter cylinder 18 to rotate through the meshing with the annular gear 21. Through the arranged transmission mechanism, when the crushing cutter roller 7 rotates, the centrifugal filter cylinder 18 can be driven to rotate synchronously.

[0017] According to the present invention, when it is necessary to clean the inner wall of the centrifugal filter drum 18, the electric control valve 28 on the slag discharge pipe 24, the sewage discharge pipe 25, the material discharge pipe 27 and the water inlet pipe 31 is opened to allow the flushing water to enter the water inlet pipe 31 through the water inlet pipe 31, and then be sprayed out through the nozzle 30. In conjunction with the rotation of the centrifugal filter drum 18, the inner wall of the centrifugal filter drum 18 can be backwashed, so that the solid impurities are discharged from the inside of the centrifugal filter drum 18 along the water flow through the material discharge pipe 27, and then discharged from the inside of the centrifugal filter 2 through the slag discharge pipe 24, and part of the sewage is discharged through the sewage discharge pipe 25. Through the provided cleaning mechanism, the filtering components of the centrifugal filter 2 can be automatically cleaned. Compared with the existing manual cleaning, not only the cleaning efficiency of the filtering components of the centrifugal filter 2 is improved, but also the labor intensity of the staff is reduced.

[0018] According to the present invention, when the heater inside the distiller distills and purifies the waste oil containing water, the high-temperature steam enters the first connecting frame through the steam pipe, and enters the second connecting frame after passing through the heat exchange pipe. The waste oil separated from the oil-water separator by the oil-water separator enters the heat energy recovery device. The high-temperature steam and the waste oil are heat-exchanged through the heat exchange pipe, and the high-temperature steam is condensed into a liquid state and then discharged through the second drain pipe. The preheated waste oil enters the distiller for distillation and purification. The heat energy recovery mechanism can not only recycle the preheated steam, but also preheat the waste oil, thereby effectively improving the distillation and purification efficiency of the waste oil.

An electric control valve 28 is installed on the oil discharge pipe 43; The kitchen waste oil and water is put into the inside of the crusher 6 through a feed hopper 8. The crushing knife roller 7 and the stirring rod 10 are driven to rotate simultaneously through a driving mechanism. The solids in the oil and water are crushed by the crushing knife roller 7, and then enter the centrifugal filter cylinder 18 through the feed pipe 19. The crushing knife roller 7 drives the centrifugal filter cylinder 18 to rotate through a transmission mechanism, so that the centrifugal filter cylinder 18 generates centrifugal force to separate the solid and liquid of the oil and water. The filtered oil-water mixture is separated by the oil-water separator 3. The sewage is discharged through the first drain pipe 35. The gutter oil enters the inside of the distiller 5 after passing through the inside of the heat energy recovery device 4. The gutter oil is distilled by heating to further remove the moisture in the gutter oil. The purified gutter oil is discharged through the oil discharge pipe 43. Through this gutter oil recovery and treatment equipment, the gutter oil in the kitchen waste oil and water can be separated, and at the same time, the gutter oil can be purified, saving the subsequent treatment cost of the gutter oil. The gutter oil can be recycled, and the recovery and treatment equipment is highly integrated, reducing the floor area of the recovery and treatment equipment, so as to be suitable for the recovery of kitchen gutter oil.

[0023] Please refer to Figures 1 to 6, the driving mechanism includes a dual-axis motor 11. The dual-axis motor 11 is installed in the middle of the top end of the box body 1.

A third reversing gear 14 is installed at the shaft end of the crushing knife roller 7 corresponding to the first reversing gear 12, and a fourth reversing gear 15 is installed at the shaft end of the stirring rod 10 corresponding to the second reversing gear 13. The first reversing gear 12 and the second reversing gear 13 are respectively meshed with the third reversing gear 14 and the fourth reversing gear 15, and the outer diameter of the second reversing gear 13 is smaller than the outer diameter of the fourth reversing gear 15. When the dual-axis motor 11 works, it drives the first reversing gear 12 and the second reversing gear 13 to rotate simultaneously. The first reversing gear 12 drives the crushing knife roller 7 to rotate through meshing with the third reversing gear 14. At the same time, the second reversing gear 13 drives the stirring rod 10 to rotate through meshing with the fourth reversing gear 15. And the outer diameter of the second reversing gear 13 is smaller than the outer diameter of the fourth reversing gear 15, so that the dual-axis motor 11 can drive the crushing knife roller 7 to rotate at a high speed while driving the stirring rod 10 to rotate at a low speed. Thus, through a single dual-axis motor 11, it can drive the crushing knife roller 7 to crush the material and drive the stirring rod 10 to stir the distilled gutter oil at the same time, which can reduce the number of driving motors, and thus effectively reduce the production cost of the equipment (the components of the driving mechanism are protected by a protective cover during actual use. In order to show its structure in this solution, it is expressed in a naked form).

[0024] Please refer to Figures 1 to 6 , the transmission mechanism includes transmission gears 20. Transmission gears 20 are installed at the shaft ends of the crushing knife rollers 7 close to the lower part of the pulverizer 6. The transmission gears 20 are meshed with each other. A ring gear 21 is installed at the top of the centrifugal filter cylinder 18. A driving gear 22 is rotatably connected to the inner top of the centrifugal filter 2 close to the ring gear 21. The driving gear 22 and the corresponding transmission gear 20 are fixedly connected by a transmission rod 23. The two crushing knife rollers 7 can rotate in opposite directions simultaneously through the transmission gears 20. At the same time, the transmission gear 20 drives the driving gear 22 to rotate through the transmission rod 23. The driving gear 22 can drive the centrifugal filter cylinder 18 to rotate through meshing with the ring gear 21. Through the set transmission mechanism, when the crushing knife roller 7 rotates, it can drive the centrifugal filter cylinder 18 to rotate synchronously.

[0025] Please refer to Figures 1 to 6The cleaning mechanism includes a slag discharge pipe 24, a slag discharge pipe 24 is connected to the side of the centrifugal filter 2 near the bottom, a sewage discharge pipe 25 is connected to the side of the centrifugal filter 2 near the top of the partition 16, a pipe groove 26 is opened in the middle of the bottom end of the centrifugal filter cylinder 18, a discharge pipe 27 is installed in the middle of the partition 16, the top of the discharge pipe 27 passes through the interior of the partition 16 and the pipe groove 26, the discharge pipe 27 is connected to the bottom of the centrifugal filter 2 and forms a rotation connection, a flushing pipe 29 is installed on the inner wall of the centrifugal filter 2 corresponding to the centrifugal filter cylinder 18, and a nozzle 30 is equidistantly installed on the flushing pipe 29 near the side of the centrifugal filter cylinder 18, and a water inlet pipe 31 is connected to the middle of the flushing pipe 29. The slag discharge pipe 24, the sewage discharge pipe 25, the discharge pipe 27 and the water inlet pipe 31 are also installed with an electric control valve 28. The inner bottom of the centrifugal filter 2 is tilted downward toward the slag discharge pipe 24, and the rotation connection between the centrifugal filter cylinder 18 and the partition 16 is connected by a dynamic sealing ring. The centrifugal filter drum 18 is sealed and connected with the discharge pipe 27 through a dynamic sealing ring. When the inner wall of the centrifugal filter drum 18 needs to be cleaned, the electric control valve 28 on the slag discharge pipe 24, the sewage discharge pipe 25, the discharge pipe 27 and the water inlet pipe 31 is opened to allow the flushing water to enter the water inlet pipe 31 through the water inlet pipe 31, and then be sprayed out through the nozzle 30. In conjunction with the rotation of the centrifugal filter drum 18, the inner wall of the centrifugal filter drum 18 can be backwashed, so that the solid impurities are discharged from the inside of the centrifugal filter drum 18 through the discharge pipe 27 along the water flow, and then discharged from the inside of the centrifugal filter 2 through the slag discharge pipe 24, and part of the sewage is discharged through the sewage discharge pipe 25. The cleaning mechanism can automatically clean the filter components of the centrifugal filter 2. Compared with the existing manual cleaning, it not only improves the cleaning efficiency of the filter components of the centrifugal filter 2, but also reduces the labor intensity of the staff.

[0026] See also Figures 1 to 6 A delivery pump 32 is installed inside the box body 1 near the centrifugal filter 2 and the oil-water separator 3. The delivery pump 32 is connected to the centrifugal filter 2 on the side above the partition 16 through a suction pipe 33. The delivery pump 32 is connected to the oil-water separator 3 through a delivery pipe 34. When the delivery pump 32 is working, the filtered oil-water mixture is extracted through the suction pipe 33 and delivered to the inside of the oil-water separator 3 through the delivery pipe 34.

[0027] See also Figures 1 to 6, the heat energy recovery mechanism includes a first connecting frame 38. The upper and lower inner parts of the heat energy recovery device 4 are respectively equipped with a first connecting frame 38 and a second connecting frame 39. The bottom end of the second connecting frame 39 is connected to a second drain pipe 40. A plurality of heat exchange pipes 41 are equidistantly connected between the first connecting frame 38 and the second connecting frame 39. The first connecting frame 38 is connected to the top of the distiller 5 through a steam pipe 42. When the internal heater 9 in the distiller 5 (the temperature control component set in the distiller 5 is a commonly used control unit in the prior art, which has nothing to do with the technical problem to be solved by this solution, so the principle and function of the temperature control component are not described in detail) distills and purifies the water-containing gutter oil, the high-temperature steam enters the inside of the first connecting frame 38 through the steam pipe 42, enters the inside of the second connecting frame 39 after passing through the heat exchange pipes 41, and the gutter oil that has undergone preliminary oil-water separation by the oil-water separator 3 enters the inside of the heat energy recovery device 4. The high-temperature steam and the gutter oil are heat-exchanged through the heat exchange pipes 41. After the high-temperature steam is condensed into a liquid state, it is discharged through the second drain pipe 40. The preheated gutter oil enters the distiller 5 for distillation and purification. Through this heat energy recovery mechanism, not only can the preheating of the steam be recovered and utilized, but also the gutter oil can be preheated, thereby effectively improving the distillation and purification efficiency of the gutter oil.

[0028] Working principle: This is a gutter oil recycling and treatment device in the field of kitchen waste. The kitchen waste oil and water are put into the internal part of the crusher 6 through the feed hopper 8. The driving mechanism drives the crushing cutter roller 7 and the stirring rod 10 to rotate simultaneously. The solid in the oil and water is crushed by the crushing cutter roller 7, and then enters the centrifugal filter cylinder 18 through the feed pipe 19. The crushing cutter roller 7 drives the centrifugal filter cylinder 18 to rotate through the transmission mechanism, so that the centrifugal filter cylinder 18 generates centrifugal force to separate the solid and liquid of the oil and water. The filtered oil-water mixture is separated by the oil-water separator 3. The sewage is discharged through the first drain pipe 35. The gutter oil enters the internal part of the heat energy recovery device 4 and then enters the internal part of the distiller 5. The gutter oil is distilled by heating to further remove the moisture in the gutter oil. The purified gutter oil is discharged through the oil discharge pipe 43. Through this gutter oil recycling and treatment device, the gutter oil in the kitchen waste oil and water can be separated, and at the same time, the gutter oil can be purified, saving the subsequent treatment cost of the gutter oil. The gutter oil can be recycled, and the recycling and treatment device is highly integrated, reducing the floor area of the recycling and treatment device, so as to be suitable for the recycling of kitchen gutter oil. When the double-shaft motor 11 works, it drives the first reversing gear 12 and the second reversing gear 13 to rotate simultaneously. The first reversing gear 12 drives the crushing cutter roller 7 to rotate through the meshing with the third reversing gear 14. At the same time, the second reversing gear 13 drives the stirring rod 10 to rotate through the meshing with the fourth reversing gear 15. The outer diameter of the second reversing gear 13 is smaller than the outer diameter of the fourth reversing gear 15, so that the double-shaft motor 11 can drive the crushing cutter roller 7 to rotate at a high speed while driving the stirring rod 10 to rotate at a low speed. Thus, through a single double-shaft motor 11, it can drive the crushing cutter roller 7 to crush the material and drive the stirring rod 10 to stir the distilled gutter oil at the same time, reducing the number of driving motors, and effectively reducing the production cost of the equipment; The crushing cutter rollers 7 on both sides can rotate in opposite directions at the same time through the transmission gear 20. At the same time, the transmission gear 20 drives the driving gear 22 to rotate through the transmission rod 23. The driving gear 22 can drive the centrifugal filter drum 18 to rotate by meshing with the ring gear 21. Through the transmission mechanism, the crushing cutter roller 7 can drive the centrifugal filter drum 18 to rotate synchronously while the centrifugal filter drum 18 rotates. When it is necessary to clean the inner wall of the centrifugal filter drum 18, the electric control valve 28 on the slag discharge pipe 24, the sewage discharge pipe 25, the discharge pipe 27 and the water inlet pipe 31 is opened to allow the flushing water to enter the water inlet pipe 31 through the water inlet pipe 31, and then spray out through the nozzle 30. In conjunction with the rotation of the centrifugal filter drum 18, the inner wall of the centrifugal filter drum 18 can be backwashed, so that the solid impurities are discharged from the inside of the centrifugal filter drum 18 through the discharge pipe 27 along the water flow, and then discharged from the inside of the centrifugal filter 2 through the slag discharge pipe 24, and part of the sewage is discharged through the sewage discharge pipe 25. Through the cleaning mechanism, the filtering components of the centrifugal filter 2 can be automatically cleaned. Compared with the existing manual cleaning, it not only improves the cleaning efficiency of the filter components of the centrifugal filter 2, but also reduces the labor intensity of the staff. When the internal heater 9 of the distiller 5 (the temperature control component arranged in the distiller 5 is an existing commonly used control unit, which is irrelevant to the technical problem to be solved by this scheme, and therefore the principle and function of the temperature control component are not described in detail) distills and purifies the water-containing waste oil, the high-temperature steam enters the first connecting frame 38 through the steam pipe 42, and enters the second connecting frame 39 after passing through the heat exchange pipe 41, and the waste oil after the preliminary oil-water separation of the oil-water separator 3 enters the interior of the heat energy recovery device 4, and the high-temperature steam and the waste oil are heat-exchanged by the heat exchange pipe 41, and the high-temperature steam is condensed into a liquid state and then discharged through the second drain pipe 40, and the preheated waste oil enters the distiller 5 for distillation and purification. By this heat energy recovery mechanism, not only can the steam preheating be recycled, but also the waste oil can be preheated, thereby effectively improving the distillation and purification efficiency of the waste oil.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
