Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a slag removal and filtration device for treating kitchen waste wastewater. Background Technology

[0002] The role and significance of kitchen wastewater treatment are extremely important. Kitchen wastewater contains a large amount of organic matter, grease, and nutrients. If directly discharged into natural water bodies, it will cause eutrophication, leading to water quality deterioration and damage to aquatic ecosystems. After treatment, the negative impact on the environment is reduced, protecting the health of the aquatic ecosystem. Through kitchen wastewater treatment, the treated wastewater can be used for agricultural irrigation, industrial water use, etc., realizing the recycling of water resources, reducing the demand for freshwater resources, and alleviating the problem of water scarcity. Grease in kitchen wastewater easily solidifies in pipes, gradually accumulating to form grease deposits, leading to pipe blockage and equipment damage. Kitchen wastewater treatment can effectively remove grease, reduce the risk of pipe blockage, and extend the service life of pipes and equipment. Untreated kitchen wastewater may contain a large number of bacteria and harmful substances. If discharged indiscriminately, it will pollute the soil and groundwater, threatening human health. Kitchen wastewater treatment can effectively remove harmful substances and bacteria, ensuring public health and people's health and safety.

[0003] Currently, there are still some shortcomings in the slag removal and filtration equipment used in the treatment of kitchen wastewater. For example, it is prone to clogging, which affects work efficiency, and the filtration effect needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a slag removal and filtration device for treating kitchen waste sewage, which can efficiently remove waste residue from kitchen waste sewage through needle filtration.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A slag removal and filtration device for treating kitchen waste sewage includes an upward-facing main housing shell and a slag removal and filtration mechanism disposed within the main housing shell.

[0007] The slag removal and filtration mechanism includes a slag removal and filtration support shell disposed within the main housing shell. The slag removal and filtration support shell is a conical shell with its opening facing downwards.

[0008] The slag removal filter support shell has multiple through holes for fixing filter plates, and a slag removal filter plate is fixedly installed inside the through holes.

[0009] The top of the main body housing is fixedly provided with a support end cap with an opening facing downwards. The support end cap has a vertically penetrating lifting and receiving hole. A lifting support cylinder with an opening facing downwards is fixedly provided in the lifting and receiving hole. A lifting drive cylinder with an opening facing upwards is slidably fitted inside the lifting support cylinder.

[0010] The lower end of the lifting drive cylinder is fixedly connected to the top of the slag removal filter support shell via a vertically extending lifting connecting column;

[0011] The lifting drive cylinder is driven by an electrically controlled telescopic rod to slide vertically inside the lifting support cylinder;

[0012] An annular and hollow slag discharge ring is fixed on the outside of the main body housing. The inner side of the slag discharge ring is connected to the inside of the main body housing through multiple slag discharge holes. Multiple slag discharge pipes connected to the inside of the slag discharge ring are fixed on the lower side of the slag discharge ring. The slag discharge pipes extend spirally downward along the outer wall of the main body housing.

[0013] Preferably, an annular stirring drive housing with its opening facing downward is fixedly provided on the outside of the lifting connecting column. A stirring drive ring is rotatably fitted inside the stirring drive housing. The stirring drive ring is driven by a motor to rotate around a vertical axis. Multiple spiral stirring blades are fixedly connected to the stirring drive ring. The spiral stirring blades are spirally extended along the upper side of the slag removal and filtration support housing.

[0014] Preferably, a sliding engagement ring is fixedly provided at the lower edge of the slag removal filter support shell, and the sliding engagement ring slides vertically within the main body housing shell.

[0015] Note: The sliding fit ring is set to slide and connect with the inner side wall of the main body housing, which can provide better support for the slag removal and filtration support shell.

[0016] Preferably, the lower end of the lifting connecting column has a downward-facing rotating receiving hole, and a rotating support column is rotatably fitted inside the rotating receiving hole. The rotating support column is driven by a motor to rotate around a vertical axis. Multiple air pipes are fixedly installed at the lower end of the rotating support column. The air pipes extend along the generatrix direction parallel to the slag removal filter support shell, and the upper side of the air pipes has multiple air jet holes that communicate with each other inside and outside.

[0017] Explanation: Multiple air pipes installed on the lower side of the slag removal filter support shell are used to spray high-speed airflow from bottom to top onto each slag removal filter plate, cleaning away the fine waste residue remaining on the slag removal filter plate and ensuring that the slag removal filter plate always maintains high working efficiency.

[0018] Preferably, the vent pipe is connected to the lower end of the rotating support column via a tilting mechanism. The tilting mechanism includes multiple tilting mechanism fixed disks fixed to the lower end of the rotating support column. The axis of the tilting mechanism fixed disks extends along the generatrix parallel to the slag removal filter support shell. A tilting mechanism rotating disk is rotatably fitted on the side of the tilting mechanism fixed disk away from the rotating support column. The tilting mechanism rotating disk is driven by a motor to rotate around the axis of the tilting mechanism fixed disk. The vent pipe is fixedly connected to the side of the tilting mechanism rotating disk away from the rotating support column.

[0019] Note: When the vent pipe is not in use, the tilting mechanism will rotate the vent pipe so that the multiple air jets on the vent pipe are located on the lower side of the vent pipe, thus preventing oil from clogging the air jets.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the utility model has a reasonable structural design and is easy to operate. It uses a circulating lifting method to clean and filter out the waste residue in kitchen wastewater, and pushes the waste residue into the slag removal outer ring shell through multiple spiral stirring blades. This timely discharges the waste residue on the upper side of the slag removal filter support shell, avoiding the waste residue from clogging each slag removal filter plate and thus affecting the overall filtration efficiency.

[0021] By using multiple air pipes located on the lower side of the slag removal filter support shell, high-speed airflow is sprayed from bottom to top onto each slag removal filter plate to remove the fine waste residue remaining on the slag removal filter plate, so that the slag removal filter plate always maintains high working efficiency.

A lifting support cylinder 13 with the opening facing downward is fixedly provided inside the lifting and receiving hole 121. A lifting drive cylinder 131 with the opening facing upward is slidably fitted inside the lifting support cylinder 13.

[0033] The lower end of the lifting drive cylinder 131 is fixedly connected to the top of the slag removal filter support shell 21 via a vertically extending lifting connecting column 14;

[0034] The lifting drive cylinder 131 is driven by an electrically controlled telescopic rod to slide vertically inside the lifting support cylinder 13;

[0035] An annular and hollow slag discharge ring shell 231 is fixedly provided on the outside of the main body housing shell 11. The inner side of the slag discharge ring shell 231 is connected to the inside of the main body housing shell 11 through multiple slag discharge holes 232. Multiple slag discharge pipes 233 connected to the inside of the slag discharge ring shell 231 are fixedly provided on the lower side of the slag discharge ring shell 231. The slag discharge pipes 233 extend spirally downward along the outer wall of the main body housing shell 11.

[0036] An annular stirring drive housing 31 with its opening facing downwards is fixedly provided on the outside of the lifting connecting column 14. A stirring drive ring 311 is rotatably fitted inside the stirring drive housing 31. The stirring drive ring 311 is driven by a motor to rotate around a vertical axis. Multiple spiral stirring blades 312 are fixedly connected to the stirring drive ring 311. The spiral stirring blades 312 extend spirally along the upper side of the slag removal and filtration support housing 21.

[0037] The lower end of the lifting connecting column 14 has a downward-facing rotating receiving hole 321. A rotating support column 322 is rotatably fitted inside the rotating receiving hole 321. The rotating support column 322 is driven by a motor to rotate around a vertical axis. Multiple air pipes 33 are fixedly installed at the lower end of the rotating support column 322. The air pipes 33 extend along the generatrix parallel to the slag removal filter support shell 21. The upper side of the air pipes 33 has multiple air jet holes that communicate with each other inside and outside.

[0038] The vent pipe 33 is connected to the lower end of the rotating support column 322 via the tilting mechanism 35. The tilting mechanism 35 includes multiple tilting mechanism fixing disks 351 fixed to the lower end of the rotating support column 322. The axis of the tilting mechanism fixing disks 351 extends along the generatrix parallel to the slag removal filter support shell 21. A tilting mechanism rotating disk 352 is rotatably fitted on the side of the tilting mechanism fixing disks 351 away from the rotating support column 322. The tilting mechanism rotating disk 352 is driven by a motor to rotate around the axis of the tilting mechanism fixing disks 351. The vent pipe 33 is fixedly connected to the side of the tilting mechanism rotating disk 352 away from the rotating support column 322.

[0039] In practical application, the top of the support end cover 12 is fixedly provided with multiple material input pipes that are connected to its interior, and the outer wall of the main body housing 11 near the bottom is fixedly provided with a material output pipe that is connected to its interior.

[0040] The kitchen wastewater to be treated is injected into the support end cover 12 through the material input pipe. The kitchen wastewater injected from each material input pipe falls from top to bottom onto the top of the slag removal and filtration support shell 21.

[0041] Waste residue in kitchen wastewater is intercepted by multiple slag removal filter plates 22 and concentrated at the top of the slag removal filter support shell 21. The stirring drive ring 311 driven by the motor rotates around the vertical axis. The stirring drive ring 311 drives multiple spiral stirring blades 312 to rotate together. The spiral stirring blades 312 scrape the waste residue collected at the top of the slag removal filter support shell 21 and push the waste residue continuously towards the edge of the slag removal filter support shell 21.

[0042] Under normal working conditions, the slag removal filter support shell 21 is positioned below the slag removal outer discharge ring shell 231. When it is necessary to discharge the waste slag collected at the top of the slag removal filter support shell 21, the lifting drive cylinder 131 is driven by the electric telescopic rod to move vertically within the lifting support cylinder 13. The lifting drive cylinder 131 drives the lifting connecting column 14 to move upward together with the slag removal filter support shell 21, so that the edge of the slag removal filter support shell 21 is flush with the lower side of the slag removal outer discharge ring shell 231. Under the continuous pushing of the spiral stirring blades 312, the waste slag concentrated at the top edge of the slag removal filter support shell 21 is pushed into the slag removal outer discharge ring shell 231 through the slag removal outer discharge hole 232. The waste slag in the slag removal outer discharge ring shell 231 is then discharged through multiple slag removal outer discharge pipes 233.

[0043] Air is introduced into multiple vent pipes 33, and the air in the vent pipes 33 is ejected from multiple jet holes on its side wall. The airflow ejected from the jet holes passes through each slag removal filter plate 22 from bottom to top, and peels off the waste residue attached to the slag removal filter plate 22.

[0044] After filtration, the kitchen wastewater is concentrated at the bottom of the main container shell 11 and then discharged through the material output pipe.
