Description

Technical Field

[0001] The utility model relates to the technical field of sewage filtration, and particularly relates to a kitchen sewage filtration device. Background Art

[0002] Kitchen sewage refers to the wastewater generated by kitchen life and food processing activities. Kitchen sewage usually includes food residues, grease, etc. When discharging kitchen sewage through a pipeline, in order to avoid pipeline blockage, it is usually necessary to filter it.

[0003] After retrieval, the Chinese patent "A Kitchen Sewage Filtration Device" with the authorization announcement number "CN 212440359U" increases the separation effect of water and oil through the oil-absorbing paper in the middle of the filter screen, and drives the cleaning plate on the connecting rod by the power of a waterproof servo motor to clean the surface of the filter screen, which facilitates the cleaning of the surface of the filter screen.

[0004] Although the above application can filter sewage, during the filtration process, although the oil-absorbing paper will adsorb grease, there is still grease adhering to the surface and pores of the semi-circular filter screen. When the cleaning plate cleans its surface, it will scrape the surface impurities and grease into adjacent filter holes. Due to the poor fluidity of grease, it is easy to cause filter hole blockage, thus affecting the filtration effect.

[0005] Therefore, a kitchen sewage filtration device is proposed to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a kitchen sewage filtration device to solve the above problems, and improve the problem that although the oil-absorbing paper will adsorb grease during the filtration process, there is still grease adhering to the surface and pores of the semi-circular filter screen. When the cleaning plate cleans its surface, it will scrape the surface impurities and grease into adjacent filter holes. Due to the poor fluidity of grease, it is easy to cause filter hole blockage, thus affecting the filtration effect.

A kitchen waste water filtering device includes: a filtering barrel, a water inlet pipe is connected to the top end of the filtering barrel, and a filtering mechanism is arranged inside the filtering barrel; wherein, the filtering mechanism includes a first funnel fixedly connected to the upper end of the inner wall of the filtering barrel, a chamber is opened inside the first funnel, a filtering pipe distributed in a ring shape is embedded and installed on the inner wall of the first funnel, a collecting barrel is fixedly connected to the bottom end of the first funnel, a rotating ring is rotatably connected to the inner top wall of the first funnel, an annular pipe is fixedly connected to the bottom end of the rotating ring, a plurality of air outlet pipes are communicated with the lower end surface of the annular pipe, a hot air blower is installed on the upper end surface of the filtering barrel, a connecting pipe is communicated between the air outlet of the hot air blower and the annular pipe, and an exhaust pipe is communicated with the surface of the first funnel.

[0008] Preferably, the filtering mechanism further includes a second funnel fixedly connected to the lower end of the inner wall of the filtering barrel. A chamber is opened inside the second funnel and filled with an aqueous solution. An oil absorbent paper is arranged on the inner wall of the second funnel. A drain pipe is communicated with the bottom end of the second funnel. The oil absorbent paper adsorbs the oil in the waste water, and under the action of the cooling water in the chamber of the second funnel, the surface of the second funnel is cooled, which is beneficial to reducing the temperature of the waste water passing through the oil absorbent paper, so that the oil in the waste water solidifies better and adsorbs on the oil absorbent paper, improving the collection effect of the oil in the waste water.

A gear ring is rotatably connected to the surface of the filtering barrel. The surface of the installation ring is fixedly connected to the inner wall of the gear ring. The output shaft of the servo motor is fixedly connected to a gear, and the gear is meshed with the gear ring. When driving the plurality of air outlet pipes to blow hot air into the chamber of the first funnel, it rotates reciprocally, which is beneficial to making the hot air spread more evenly in the chamber of the first funnel, so that the surfaces of the plurality of filtering pipes and the surface of the first funnel are heated evenly, and it is beneficial to making the oil in the waste water flow better.

[0010] Preferably, a first guiding plate is fixedly connected to the inner top wall of the filtering barrel. The overall shape of the first guiding plate is conical. It is beneficial to disperse the waste water, so that the waste water falls on the first funnel more evenly, and it is beneficial to making the waste water flow downward from the higher end of the first funnel, increasing the flow time of the waste water on the surface of the first funnel, thereby improving the filtering effect of the filtering pipe on the waste water.

[0011] Preferably, a second guiding plate is fixedly connected to the surface of the collecting barrel. An included angle is formed between the surface of the second guiding plate and the horizontal plane.

[0012] Preferably, a guiding ring is fixedly connected to the top end of the mounting ring, and the vertical cross-section of the guiding ring is a right triangle. This can prevent impurities in the sewage from staying at the top end of the mounting ring.

Under the action of the inclined surface on the inner surface of the first funnel and the water flow, it is beneficial for the collecting cylinder to collect the filtered impurities. At the same time, under the action of the hot air blower, hot air enters the annular pipe through the connecting pipe and is ejected through multiple air outlet pipes, which is beneficial for heating the surface of the first funnel and the filter pipes, increasing the fluidity of the impurities and the grease in the waste water when passing through the surface of the first funnel and the inner wall of the annular pipe, making the grease flow downward better, avoiding the adhesion of the grease on the surface of the first funnel and the inner wall of the filter pipes, thus preventing the blockage of the filter pipes and ensuring the filtering effect of the waste water;

[0017] 2. The oil-absorbing paper is used to adsorb the grease in the waste water, and the surface of the second funnel is cooled under the action of the cooling water in the chamber of the second funnel, which is beneficial for reducing the temperature of the waste water passing through the oil-absorbing paper, so that the grease in the waste water solidifies better and adsorbs on the oil-absorbing paper, improving the collection effect of the grease in the waste water;

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] During specific implementation: As Figures 1-5 shown, a kitchen waste water filtering device includes: a filter barrel 1, a water inlet pipe 2 is connected to the top end of the filter barrel 1, and a filtering mechanism 3 is arranged inside the filter barrel 1; wherein, the filtering mechanism 3 includes a first funnel 31 fixedly connected to the upper end of the inner wall of the filter barrel 1, a chamber is provided inside the first funnel 31, a filter pipe 32 distributed in a ring shape is embedded and installed on the inner wall of the first funnel 31, a collection barrel 38 is fixedly connected to the bottom end of the first funnel 31, a rotating ring 33 is rotatably connected to the inner top wall of the first funnel 31, an annular pipe 34 is fixedly connected to the bottom end of the rotating ring 33, a plurality of air outlet pipes 35 are communicated with the lower end of the surface of the annular pipe 34, a hot air blower 36 is installed on the upper end surface of the filter barrel 1, a connecting pipe 37 is communicated between the air outlet of the hot air blower 36 and the annular pipe 34, and an exhaust duct 319 is communicated with the surface of the first funnel 31.

[0027] Both ends of the filter pipe 32 penetrate through the first funnel 31, and the other end of the exhaust pipe 319 penetrates through the filter barrel 1. When filtering kitchen sewage, the kitchen sewage is poured into the filter barrel 1 through the water inlet pipe 2. At this time, the sewage flows to the inner side of the first funnel 31 and the impurities in the sewage are filtered through the multiple filter pipes 32. The impurities in the sewage will stay on the inner surface of the first funnel 31, and under the action of the water flow and the inclined surface of the first funnel 31, the impurities will flow into the collection cylinder 38. The bottom end of the collection cylinder 38 is provided with a plurality of through holes with smaller diameters. While filtering the sewage, the hot air blower 36 is started by the controller, and the hot air is introduced into the annular pipe 34 through the connecting pipe 37 by the hot air blower 36 and blown into the chamber of the first funnel 31 through the multiple air outlet pipes 35 to heat the surface of the first funnel 31 and the surface of the filter pipe 32, so as to increase the fluidity of the grease in the sewage when passing through the surface of the first funnel 31 and the inner wall of the annular pipe 34, make the grease flow downward better, and ensure the normal flow of air through the exhaust pipe 319.

[0028] As Figure 2 and Figure 5 As shown, the filtering mechanism 3 further includes a second funnel 313 fixedly connected to the lower end of the inner wall of the filter barrel 1. The inside of the second funnel 313 is provided with a chamber and filled with an aqueous solution. An oil absorbent paper 314 is arranged on the inner wall of the second funnel 313, and a drain pipe 315 is communicated with the bottom end of the second funnel 313.

[0029] A liquid guide pipe is communicated with the lower end of the surface of the second funnel 313, and the aqueous solution can be filled into the chamber of the second funnel 313 through the liquid guide pipe. And when filtering the kitchen sewage, the aqueous solution filled into the second funnel 313 is the cooled aqueous solution. When the multiple filter pipes 32 filter the sewage, the grease and water will enter the inner side of the second funnel 313, and the oil absorbent paper 314 adsorbs the grease. Under the action of the cooling water in the chamber of the second funnel 313, the temperature of the surface of the second funnel 313 will be reduced, so that the temperature of the sewage passing through the oil absorbent paper 314 is reduced. At this time, the grease in the sewage will solidify and adsorb on the oil absorbent paper 314. At this time, the water will enter the sewage discharge pipe through the drain pipe 315.

[0030] A sealing plate is arranged on the surface of the filter barrel 1, and the sealing plate is installed on the filter barrel 1 through bolts. When it is necessary to clean the impurities in the collection cylinder 38 and replace the oil absorbent paper 314, the sealing plate can be drilled.

[0031] As Figure 2 and Figure 3As shown in the figure, a servo motor 39 is fixedly connected to the surface of the filter barrel 1. An installation ring 310 is rotatably connected to the inner wall of the filter barrel 1. The top end of the rotating ring 33 penetrates through the first funnel 31 and is fixedly connected to the bottom end of the installation ring 310. A gear ring 311 is rotatably connected to the surface of the filter barrel 1. The surface of the installation ring 310 is fixedly connected to the inner wall of the gear ring 311. The output shaft of the servo motor 39 is fixedly connected to a gear 312, and the gear 312 is meshed with the gear ring 311. The top end of the installation ring 310 is fixedly connected to a guiding ring 316, and the vertical section of the guiding ring 316 is a right triangle.

[0032] When the device is in use, the operation mode of the servo motor 39 is set through the controller, so that the output shaft of the servo motor 39 rotates reciprocally after starting. When filtering sewage, the servo motor 39 is started through the controller, so that the output shaft of the servo motor 39 drives the gear 312 to rotate reciprocally, and drives the gear ring 311 to rotate reciprocally through the gear 312, so that the installation ring 310 drives the rotating ring 33 and the annular pipe 34 to rotate reciprocally, so that when multiple air outlet pipes 35 blow hot air into the chamber of the first funnel 31, they rotate reciprocally.

[0033] As Figure 2 shown in the figure, a first guiding plate 317 is fixedly connected to the inner top wall of the filter barrel 1. The overall shape of the first guiding plate 317 is conical. The maximum diameter of the first guiding plate 317 is smaller than the maximum diameter of the inner wall of the first funnel 31. When sewage enters the filter barrel 1 through the water inlet pipe 2, the first guiding plate 317 diffuses the sewage, and under the action of the first guiding plate 317, the sewage flows downward from the higher end of the inner surface of the first funnel 31.

[0034] As Figure 2 and Figure 3 shown in the figure, a second guiding plate 318 is fixedly connected to the surface of the collection barrel 38. An included angle is formed between the surface of the second guiding plate 318 and the horizontal plane. The sewage filtered by the filter pipe 32 will flow onto the second guiding plate 318, and under the action of the inclined surface of the second guiding plate 318, the sewage flows downward from the higher end of the inner surface of the second funnel 313.

[0035] As Figure 3 shown in the figure, the middle part of the connecting pipe 37 is a flexible pipe. When the installation ring 310 drives the rotating ring 33 and the annular pipe 34 to rotate, the part of the connecting pipe 37 that is a flexible pipe will deform.

[0036] As Figure 4 shown in the figure, multiple air outlet pipes 35 are annularly and equally distributed. An included angle is formed between the surface of the air outlet pipe 35 and the horizontal plane. The inclination angle of the air outlet pipe 35 is the same as the inclination angle of the inclined surface of the first funnel 31.

[0037] When the utility model is in use and filtering kitchen waste water, the hot air blower 36 is started through the controller, and the kitchen waste water is poured into the filtering barrel 1 through the water inlet pipe 2. The first guiding plate 317 will diffuse the waste water, so that the waste water flows downward from the higher end of the inner surface of the first funnel 31, and the impurities in the waste water will be filtered through a plurality of filter pipes 32. The impurities in the waste water will stay on the inner surface of the first funnel 31, and under the action of the water flow and the inclined surface of the first funnel 31, the impurities will flow into the collection barrel 38. At the same time, the hot air blower 36 will introduce hot air into the annular pipe 34 through the connecting pipe 37 and blow it into the chamber of the first funnel 31 through a plurality of air outlet pipes 35. At the same time, the servo motor 39 is started through the controller to drive the gear 312 to rotate reciprocally, thereby driving the gear ring 311, the mounting ring 310, the rotating ring 33, and the annular pipe 34 to rotate reciprocally, so that the plurality of air outlet pipes 35 rotate reciprocally during the process of blowing hot air into the chamber of the first funnel 31. The waste water filtered by the plurality of filter pipes 32 will flow downward from the higher end of the inner surface of the second funnel 313 under the action of the inclined surface of the second guiding plate 318. At this time, the oil absorbent paper 314 adsorbs the grease, and under the action of the cooling water in the chamber of the second funnel 313, the temperature of the surface of the second funnel 313 will be reduced, so that the temperature of the waste water passing through the oil absorbent paper 314 is reduced. At this time, the grease in the waste water will solidify and adsorb on the oil absorbent paper 314. At this time, the water will enter the sewage pipeline through the drain pipe 315.

[0038] The operating principle of the hot air blower 36 is that after being powered on, the blower will blow air to the heater, so that the heat generated after the heating wire is powered on exchanges heat with the passing cold air, and the air temperature at the air outlet rises. It should be noted that in the above description, the hot air blower 36, the servo motor 39, etc. are all devices with relatively mature applications in the prior art, and the specific models can be selected according to actual needs. At the same time, the power supply of the hot air blower 36 and the servo motor 39 can be powered by an internal power supply or by the mains power supply, and the specific power supply method is selected according to the situation and will not be elaborated here.

[0039] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
