Description

Technical Field

[0001] This utility model relates to the field of emulsion filtration technology, and in particular to a self-cleaning emulsion filter. Background Technology

[0002] Emulsion filtration is a crucial step in industrial production. Unfiltered emulsions accumulate impurities, disrupting the oil-water balance, affecting lubrication and cooling performance, leading to increased processing temperatures and accelerated tool wear. Through integrated technologies such as ozone sterilization, filtration can also inhibit bacterial growth, improve odor control in the workshop environment, and effectively remove solid particles, floating oil, and sediment from the emulsion. This prevents impurities from causing wear or clogging to equipment and helps maintain the chemical stability of the emulsion. During emulsion filtration, the filtration device needs to be cleaned regularly to maintain filtration efficiency.

[0003] A search revealed a Chinese patent with publication number CN220513579U, which discloses a self-cleaning emulsion filter, comprising an outer cylinder, a filter element, a cleaning component, a lifting mechanism, and a top cylinder. The filter element is installed inside the outer cylinder, and the cleaning component is installed inside the filter element. The top cylinder is fixed at the top center of the outer cylinder, and the two are connected. The lifting mechanism is fixed on the outer side of the outer cylinder.

[0004] To address the problem in the aforementioned technologies that require shutdown for cleaning, during which filtration is impossible and affects the filtration efficiency of the emulsion, a self-cleaning emulsion filter is proposed. Utility Model Content

[0005] In view of this, the present invention aims to provide a self-cleaning emulsion filter to solve or alleviate the technical problems existing in the prior art, or at least provide a beneficial alternative.

[0008] In some embodiments, the cleaning assembly includes a cleaning motor, a drive shaft, a roller, a translation drive block, and a cleaning brush. One side of the cleaning motor is fixedly connected to the rear side of the mounting bracket, one end of the drive shaft is fixedly connected to the power output end of the cleaning motor, and one end of the drive shaft is rotatably connected to one side of the cleaning sleeve. The roller is rotatably connected to one end of the drive shaft. The translation drive block is slidably connected inside the cleaning sleeve, and the roller is movably connected to a slot on the inner side of the translation drive block.

[0013] In some embodiments, a receiving plate is fixedly connected to one side of the filter cartridge.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] 1. A self-cleaning emulsion filter, wherein the filter cartridge is installed at an angle, and a drive motor drives a gear ring to rotate slowly. During operation, the lower half of the filter cartridge filters the emulsion, while the upper half is cleaned by water spraying from cleaning nozzles and a cleaning component cleaning the inner wall.

[0028] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] Example 1:

[0031] like Figure 1-6 As shown, a self-cleaning emulsion filter includes a mounting bracket 1. A filter cartridge 7 is rotatably connected inside the mounting bracket 1 and installed at an incline. A cleaning nozzle 3 and a cleaning sleeve 9 are fixedly connected to one side of the mounting bracket 1. The outlet of the cleaning nozzle 3 is slidably connected to the outer wall of the filter cartridge 7. The upper part of the cleaning sleeve 9 is slidably connected to the inner wall of the filter cartridge 7. A cleaning component is slidably connected inside the cleaning sleeve 9.

[0032] A water supply assembly 12 is fixedly connected to the water inlet end of the cleaning nozzle 3, and a recycling box 14 is fixedly connected to the bottom of the cleaning sleeve 9.

[0033] When in use, because the filter cartridge 7 is installed at an angle, objects flushed into it will move downwards due to gravity.

[0034] When using filter cartridge 7 to filter emulsion, solid debris can adhere to the inner wall of filter cartridge 7. When filter cartridge 7 is rotated to the upper side, water supply component 12 can spray water from the outside to the inside through cleaning nozzle 3 for cleaning. At this time, the sprayed water and the solid debris washed off can be received by cleaning sleeve 9 and flow into recovery box 14 from the bottom pipe. The cleaning effect can be improved by cleaning component throughout the cleaning process. At the same time, because the filter cartridge 7 is filtered from the bottom and cleaned from the top, continuous cleaning without stopping the machine can be achieved, which improves the filtration effect.

[0035] In this embodiment, the cleaning assembly includes a cleaning motor 13, a drive shaft 15, a roller 19, a translation drive block 20, and a cleaning brush 16. One side of the cleaning motor 13 is fixedly connected to the rear side of the mounting bracket 1. One end of the drive shaft 15 is fixedly connected to the power output end of the cleaning motor 13, and one end of the drive shaft 15 is rotatably connected to one side of the cleaning sleeve 9. The roller 19 is rotatably connected to one end of the drive shaft 15. The translation drive block 20 is slidably connected to the inside of the cleaning sleeve 9. The roller 19 is movably connected to the groove on the inner side of the translation drive block 20. The cleaning brush 16 is fixedly connected above the translation drive block 20.

[0036] When the cleaning motor 13 is working, the drive shaft 15 rotates, which can drive the translation drive block 20 to slide left and right through the rotation of the roller 19 installed on one side, so that the cleaning brush 16 can clean the inner wall of the filter cartridge 7 from the inside, thereby improving the cleaning effect.

[0037] In this embodiment, a plurality of water channels 17 are provided below the cleaning brush 16. A limiting boss 22 is fixedly connected to one side of the translation drive block 20. A horizontal groove is provided on the inner wall of one side of the cleaning sleeve 9. The limiting boss 22 is slidably connected to the horizontal groove on the inner wall of the cleaning sleeve 9. The limiting boss 22 can restrict the movement trajectory of the translation drive block 20, allowing the translation drive block 20 to move intelligently left and right. The water channels 17 can quickly concentrate the water and debris flushed down from above below the cleaning sleeve 9, improving the stability of cleaning.

[0038] Multiple electromagnets 11 are fixedly connected to the bottom of the cleaning sleeve 9, a micro switch 21 is fixedly connected to one side of the cleaning sleeve 9, and multiple trigger bosses 18 are fixedly connected to the inner wall edge of the filter cartridge 7. The micro switch 21 controls the connection to the multiple electromagnets 11.

[0039] When the electromagnet 11 is energized, it can attract iron filings falling from above, improving the cleaning effect on the iron filings. At the same time, when the filter cartridge 7 rotates, it drives the trigger boss 18 to squeeze the micro switch 21. The micro switch 21 will cause multiple electromagnets 11 to be briefly de-energized at the same time. This allows the iron filings to be temporarily prevented from being attracted and to flow out with the water for recycling.

[0040] In this embodiment, a recycling tank 6 and a filter nozzle 8 are fixedly connected below the mounting bracket 1. The upper end of the recycling tank 6 is slidably connected to the outer wall of the filter cartridge 7, and the filter nozzle 8 is installed inside the filter cartridge 7.

[0041] The filter nozzle 8 is connected to an external liquid supply pump, which can spray the emulsion to be filtered downwards for filtration. The recovery tank 6 is used to collect the emulsion that needs to be filtered. In this way, the emulsion can be filtered. At the same time, the filter cartridge 7 rotates continuously during the spray filtration process, so that the cleaned part of the filter cartridge 7 can be used for filtration continuously, which improves the emulsion filtration efficiency.

[0042] In this embodiment: When in use, because the filter cartridge 7 is installed at an angle, the object that is flushed into it will move downward due to gravity.

[0043] When using filter cartridge 7 to filter emulsion, solid debris can adhere to the inner wall of filter cartridge 7. When filter cartridge 7 is rotated to the upper side, water supply component 12 can spray water from the outside to the inside through cleaning nozzle 3 for cleaning. At this time, the sprayed water and the solid debris washed off can be received by cleaning sleeve 9 and flow into recovery box 14 from the bottom pipe. The cleaning effect can be improved by cleaning component throughout the cleaning process. At the same time, because the filter cartridge 7 is filtered from the bottom and cleaned from the top, continuous cleaning without stopping the machine can be achieved, which improves the filtration effect.

[0044] When the cleaning motor 13 is working, the drive shaft 15 rotates, which can drive the translation drive block 20 to slide left and right when the roller 19 installed on one side rotates, so that the cleaning brush 16 can clean the inner wall of the filter cartridge 7 from the inside, improving the cleaning effect. The limiting boss 22 can restrict the movement trajectory of the translation drive block 20, allowing the translation drive block 20 to move left and right intelligently. The water channel 17 can quickly concentrate the water and debris flushed down from above under the cleaning sleeve 9, improving the stability of cleaning.

[0045] The filter nozzle 8 is connected to an external liquid supply pump, which can spray the emulsion to be filtered downwards for filtration. The recovery tank 6 is used to collect the emulsion that needs to be filtered. In this way, the emulsion can be filtered. At the same time, the filter cartridge 7 rotates continuously during the spray filtration process, so that the cleaned part of the filter cartridge 7 can be used for filtration continuously, which improves the emulsion filtration efficiency.

[0046] Example 2:

[0047] A self-cleaning emulsion filter is described in this embodiment, which is an improvement upon Embodiment 1, as follows: Figure 1-6 As shown,

[0048] In this embodiment, a drive gear ring 4 is fixedly connected to one side of the filter cartridge 7, and a drive motor 5 is fixedly connected to one side of the mounting bracket 1. One end of the drive gear ring 4 meshes with the gear at the power output end of the drive motor 5. A positioning cover plate 2 is fixedly connected to one side of the mounting bracket 1, and one end of the positioning cover plate 2 is slidably connected to the outside of the drive gear ring 4.

[0049] The drive motor 5 has a gear installed at its power output end, which can drive the drive gear ring 4 at one end of the filter cartridge 7 to rotate, allowing the filter cartridge 7 to rotate slowly and achieve synchronous cleaning during operation.

[0050] In this embodiment, a receiving plate 10 is fixedly connected to one side of the filter cartridge 7. When the filter cartridge 7 moves above the cleaning sleeve 9, the debris inside the filter cartridge 7 will be squeezed off and caught by the receiving plate 10 and enter the recycling box 14 through the bottom hole of the cleaning sleeve 9.

[0051] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
