[0047] Modes for Carrying Out the Invention

[0048] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0049] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations such as "include" or "comprising", etc., will be understood to include the stated elements or components but not to exclude other elements or other components.

[0050] As shown in Figures 1 to 4, an environmentally friendly paint filter according to a preferred embodiment of the present invention includes an environmentally friendly paint filter 1, which includes an environmentally friendly paint filter housing 101, a filter plate 10, multiple cleaning components 11, a supply and conveying component 8 and a residual material cleaning device 14.

[0051] An upper cover 102 is provided on the environmentally friendly paint filter housing 101, a feed port 16 is provided on one side end face of the environmentally friendly paint filter housing 101, and a discharge port 5 is provided on the bottom end face of the environmentally friendly paint filter housing 101. The paint to be filtered is transported into the environmentally friendly paint filter 1 through the feed port 16, and after the paint is filtered, it is transported to the finished product storage through the discharge port 5.

[0052] As shown in Figures 6 to 10, the filter plate 10 is located on the lower end face of the inner wall of the environmentally friendly paint filter housing 101. A plurality of filter holes 1001 are opened on the filter plate 10. The filter plate 10 is fixedly connected to the inner wall end face of the environmentally friendly paint filter housing 101. Various impurities, sediments and particulate matter in the paint are filtered through the filter plate 10 at the top end face of the filter plate 10.

[0053] As shown in Figures 6 and 7, a second cavity 1004 is provided in the filter plate 10, that is, the filter plate 10 is hollow, and an end face on one side of the filter plate 10 is connected to an air pump connecting pipe 901, and the air pump connecting pipe 901 is connected to the air pump 9. The air pump connecting pipe 901 passes through the environmentally friendly paint filter housing 101, and the air pump 9 is fixedly connected to the outer end face of the environmentally friendly paint filter 1, so that the air flow is transported into the environmentally friendly paint filter 1 through the air pump 9 and sprayed through the second cavity 1004.

[0054] Furthermore, when the second cavity 1004 ejects airflow, the airflow is ejected simultaneously from the upper and lower end surfaces of the multiple filter holes 1001 of the filter plate 10, thereby clearing the impurities, sediments and particulate matter accumulated in the filter holes 1001, preventing the filter holes 1001 from being blocked and affecting the normal use of the environmentally friendly paint filter 1.

[0055] Furthermore, a drainage component is provided between the second cavity 1004 of the filter plate 10 and the plurality of filter holes 1001, so as to guide the airflow ejected from the second cavity 1004 to the upper end face of the filter plate 10, and flush the impurities, sediments and particulate matter accumulated in the filter holes 1001 to the top end face of the filter plate 10, so as to facilitate the cleaning of the filter plate 10. At the same time, even if some impurities, sediments and particulate matter enter the bottom end face of the filter plate 10 through the filter holes 1001 and are discharged through the discharge port 5, the discharged impurities, sediments and particulate matter are filtered, that is, qualified paint, which does not affect the normal use of the paint.

[0056] As shown in Figure 7, the drainage component includes multiple first air flow baffles 1002 and multiple second air flow baffles 1003. A pair of upper opposite end faces of the filter plate 10 located at the multiple filter holes 1001 are fixedly connected with the first air flow baffles 1002. The angle between the first air flow baffle 1002 and the filter holes 1001 of the filter plate 10 is 30~45 degrees. A flow-limiting space with a small upper space and a large lower space is formed between the pair of first air flow baffles 1002, so that the air flow ejected through the second cavity 1004 is gathered to the filter holes 1001 located at the upper end face of the filter plate 10 to the maximum extent.

[0057] A pair of lower opposite end faces of the filter plate 10 located at the multiple filter holes 1001 are fixedly connected to the second air flow baffle 1003. The second air flow baffle 1003 is "L" shaped. The second air flow baffle 1003 is installed at a pair of opposite end faces of the filter holes 1001 at the bottom end face of the filter plate 10 at an inclination of 25 to 35 degrees, forming a diversion for the air flow ejected from the second cavity 1004, introducing the air flow upward, and ejecting impurities, sediments and particulate matter in the second cavity 1004 to the top end face of the filter plate 10.

[0058] As shown in Figures 8 to 15, multiple cleaning components 11 are abutted against the upper end surface of the filter plate 10. The cleaning components 11 include a tightening mechanism, a scraper 1103 and a scraper 1101 to remove impurities, sediments and particulate matter accumulated on the top end surface of the filter plate 10.

[0059] The first drive motor 2 includes a motor shaft 201. The first drive motor 2 is located at the top end surface of the upper cover 102. The multiple cleaning components 11 are connected to the connecting base 1501. The connecting base 1501 is fixedly connected to the scraper connecting shaft 202. The scraper connecting shaft 202 is connected to the motor shaft 201. The first drive motor 2 drives the scraper connecting shaft 202 to rotate, and then drives the cleaning component 11 to rotate, so that the scraper 1103 rotates and scrapes away impurities, sediments, and particulate matter accumulated on the filter plate 10.

[0060] A second groove matching the scraper 1103 is provided on the scraper 1101, and the top end face of the scraper 1103 is fixedly connected to the limiting block 11031. A third groove matching the limiting block 11031 is provided on the scraper 1101, and the limiting block 11031 and the scraper 1103 slide in the second groove and the third groove.

[0061] The projection of the limit block 11031 on the horizontal plane is larger than the projection of the scraper 1103 on the horizontal plane, and the limit block 11031 limits the scraper 1103 .

[0062] The bottom end surface of the scraper 1103 protrudes from the bottom end surface of the scraper plate 1101 , so that the scraper 1103 can remove impurities, sediments and particulate matter accumulated on the top end surface of the environmentally friendly paint filter 1 .

[0063] Furthermore, the tensioning mechanism includes an electromagnet 11032 , and a first limiting groove 11033 matching the electromagnet 11032 is provided on the scraper 1101 , and the projection of the first limiting groove 11033 on the horizontal plane is larger than the projection of the electromagnet 11032 on the horizontal plane.

[0064] Specifically, when it is necessary to adjust the distance between the scraper 1103 and the bottom end face of the scraper plate 1101 so that it can better remove the accumulated impurities, sediments and particulate matter, the electromagnet 11032 is turned on, and the electromagnet 11032 starts the adsorption scraper 1103 to move the scraper 1103 upward. At this time, the distance between the scraper 1103 and the bottom end face of the scraper plate 1101 is smaller, and the thickness of the impurities, sediments and particulate matter accumulated on the surface of the filter plate 10 is lower. When the electromagnet 11032 is not started, the distance between the scraper 1103 and the bottom end face of the scraper plate 1101 is larger, and the thickness of the impurities, sediments and particulate matter accumulated on the surface of the filter plate 10 is higher.

[0065] Furthermore, the operator can choose whether to start the electromagnet 11032 according to the current paint filtering situation. During normal use, the electromagnet 11032 is in the started state.

[0066] A pair of second limiting grooves 1107 are provided on the inner wall end face of the scraper 1101. A first sewage extraction pipe 12 and a first accelerating microbubble delivery pipe 13 are provided on the scraper 1101. The first accelerating microbubble delivery pipe 13 includes a bubble pump 3 and a plurality of accelerating microbubble nozzles 1302. The plurality of accelerating microbubble nozzles 1302 are all located on the top end face of the inner wall of the second limiting groove 1107 of the scraper 1101. The bubble pump 3 is fixedly connected to the top end face of the upper cover 102. The bubble pump 3 generates accelerating microbubbles and sprays them out through the plurality of accelerating microbubble nozzles 1302.

[0067] After the accelerated microbubbles are ejected through the multiple accelerated microbubble nozzles 1302, the accelerated microbubbles achieve a preliminary wrapping of the paint passing through the end face of the cleaning component 11. The paint enters the accelerated microbubbles, protecting the paint and preventing impurities from entering the paint. Secondly, when the accelerated microbubbles contact the end face of the filter plate 10, they explode. During the explosion, an impact force is generated, which accelerates the air pressure and increases the pressure inside the environmentally friendly paint filter housing 101, achieving the effect of energy saving and environmental protection. Finally, when the accelerated microbubbles contact the second cavity 1004 of the filter plate 10, they explode in the second cavity 1004, impacting the impurities, sediments, and particulate matter accumulated in the second cavity 1004 to the top end face of the filter plate 10, reducing the possibility of blockage of the multiple second cavities 1004 in the filter plate 10.

[0068] As shown in Figures 12 to 15, a pair of second limiting grooves 1107 are each provided with a guide assembly, and the guide assembly includes multiple airflow enhancement plates 1102. A pair of opposite end faces of a pair of second limiting grooves 1107 in multiple scrapers 1101 are each provided with airflow enhancement plates 1102, and a rotating mechanism 1106 is provided between the multiple airflow enhancement plates 1102 and the scrapers 1101, and the up and down flipping of the airflow enhancement plates 1102 is controlled by the rotating mechanism 1106.

[0069] Among them, the rotating mechanism 1106 is a common rotating mechanism in the prior art, similar to the flipping mechanism on the cup cover used in the prior art. The rotating mechanism 1106 includes a rotating shaft and a limit plate, that is, the airflow enhancement plate 1102 rotates in the limit plate on the scraper 1101 through the rotating shaft. It can also be other rotating mechanisms to realize the flipping of the first airflow baffle 1002.

[0070] Limiting plates 1104 are provided between the plurality of airflow enhancing plates 1102 and the scraping plates 1101 to limit the airflow enhancing plates 1102 in their initial state.

[0071] In the initial state, the angle between the airflow enhancement plate 1102 and the scraper 1101 is 45-50 degrees. That is, the angle between the airflow enhancement plate 1102 and the scraper 1101 is achieved by the limiting plate 1104. In the initial state, the pair of airflow enhancement plates 1102 form a micro space with a large upper opening space and a small lower opening space in the second limiting groove 1107.

[0072] In the initial state of the airflow enhancement plate 1102 , the bottom end surface of the airflow enhancement plate 1102 is parallel to the bottom end surface of the scraper 1101 . The initial state is a state where the pair of airflow enhancement plates 1102 are not subjected to force.

[0073] The material of the airflow enhancement plate 1102 is preferably one of HDPE plastic, PP plastic and PET plastic.

[0074] The first accelerating microbubble delivery pipe 13 includes a second accelerating microbubble delivery pipe 1301, multiple accelerating microbubble nozzles 1302 and a third accelerating microbubble delivery pipe 1303. The multiple accelerating microbubble nozzles 1302 are connected to the second accelerating microbubble delivery pipe 1301. The multiple cleaning components 11 are fixedly connected to the second sewage extraction pipe 1201 and the second accelerating microbubble delivery pipe 1301. The second sewage extraction pipe 1201 and the second accelerating microbubble delivery pipe 1301 are both connected to the main delivery pipe 15. The main delivery pipe 15 is connected to the second sewage extraction pipe 1201 and the second accelerating microbubble delivery pipe 1301.

[0075] The supply and delivery assembly 8 includes an outer delivery protective tube 800 and a pair of delivery pipelines 802. A first cavity 801 is opened in the outer delivery protective tube 800, and a delivery cavity 805 is opened in the pair of delivery pipelines 802. The end faces on one side of the pair of delivery pipelines 802 are respectively connected to the bubble pump 3 and the sewage pump 4, and the opposite end faces on the other side of the delivery pipeline 802 are respectively connected to the third accelerating microbubble delivery pipe 1303 and the third sewage pipeline 1203. The bottom end faces of the pair of delivery pipelines 802 both pass through the main delivery pipeline 15.

[0076] A pair of delivery pipes 802 are connected to the delivery main pipe 15, and multiple cleaning components 11 are all connected to the delivery main pipe 15, so that the bubble pump 3 can deliver the bubbles generated through one of the delivery pipes 802 and spray out the initial accelerated microbubbles through multiple accelerating microbubble nozzles 1302.

[0077] The first sewage extraction pipe 12 includes a second sewage extraction pipe 1201, multiple sewage extraction nozzles 1202 and a third sewage extraction pipe 1203. The multiple sewage extraction nozzles 1202 are all located on the top end face of the inner wall of the second limiting groove 1107 of the scraper 1101. The sewage extraction nozzles 1202 and the accelerating microbubble nozzles 1302 do not interfere with each other. The sewage extraction nozzles 1202 are connected to the second sewage extraction pipe 1201. Since the main conveying pipe 15 is connected to one of the conveying pipes 802, the sewage pump 4 delivers negative pressure through one of the conveying pipes 802, and adsorption is performed through multiple sewage extraction nozzles 1202.

[0078] Specifically, when the first drive motor 2 starts to control the cleaning component 11 to rotate and scrape away the impurities, sediments and particulate matter accumulated on the filter plate 10, the sewage pump 4 starts to deliver negative pressure to the multiple sewage nozzles 1202 through the conveying pipeline 802, so as to adsorb the impurities, sediments and particles accumulated during the scraping process of the cleaning component 11, and discharge them through the conveying pipeline 802, thereby achieving automatic cleaning of the filter plate 10 without the need for manual cleaning, and with high cleaning efficiency.

[0079] As shown in Figure 5, the bottom end face of the outer conveying protective tube 800 is fixedly connected to a second rotating ring 804, and a first rotating groove matching the second rotating ring 804 is opened on the conveying main pipeline 15. The projection of the second rotating ring 804 on the horizontal plane is smaller than the projection of the first rotating groove on the horizontal plane, so that when the conveying main pipeline 15 rotates, it is fixed in the first rotating groove of the conveying main pipeline 15 through the second rotating ring 804. Even if the conveying main pipeline 15 rotates, it will not drive the second rotating ring 804 to rotate, and the bubble pump 3 and the sewage pump 4 can convey normally through the conveying cavity 805.

[0080] The bottom end face of the delivery pipeline 802 is fixedly connected to the first rotating ring 803, and the top end face of the delivery main pipeline 15 is fixedly connected to the third sewage extraction pipeline 1203 and the third accelerating microbubble delivery tube 1303 respectively. The third sewage extraction pipeline 1203 and the third accelerating microbubble delivery tube 1303 are both provided with a second rotating groove that matches the first rotating ring 803.

[0081] The horizontal projection of the first rotating ring 803 is smaller than the horizontal projection of the second rotating groove. The third sewage extraction pipeline 1203 and the third accelerating microbubble delivery tube 1303 are connected to the main delivery pipeline 15. When the main delivery pipeline 15 rotates, the first rotating ring 803 is fixed in the second rotating groove of the third sewage extraction pipeline 1203 or the third accelerating microbubble delivery tube 1303. Even if the main delivery pipeline 15 rotates, it will not cause the delivery pipeline 802 to rotate. The bubble pump 3 and the sewage pump 4 can deliver normally through the delivery chamber 805.

[0082] Preferably, the outer wall end faces of the second rotating ring 804 and the first rotating ring 803 are fixedly connected to a wheel assembly, which includes multiple wheels and fixed seats. The fixed seats are respectively fixed to the outer wall end faces of the second rotating ring 804 and the first rotating ring 803. The wheels are fixed to the fixed seats. When the wheels rotate, the wheels rotate on the fixed seats. When the main delivery pipe 15 rotates, the wheels fit with the main delivery pipe 15 and rotate with the main delivery pipe 15, while the second rotating ring 804 and the first rotating ring 803 are fixed and do not rotate accordingly. This ensures that the second rotating ring 804 and the first rotating ring 803 are better fixed in the main delivery pipe 15 or the third sewage extraction pipe 1203 and the third accelerating microbubble delivery pipe 1303.

[0083] The third sewage extraction pipe 1203 and the third accelerating microbubble delivery pipe 1303 are respectively connected to the plurality of second sewage extraction pipes 1201 and the second accelerating microbubble delivery pipes 1301 inside the main delivery pipe 15 .

[0084] Multiple airflow enhancement plates 1102 are fixedly connected to multiple microbubble lifting plates 1105, and the multiple microbubble lifting plates 1105 include multiple rings, which are fixedly connected to form qualified accelerating microbubbles when the accelerating microbubbles pass through the multiple microbubble lifting plates 1105, thereby promoting the acceleration of the microbubbles.

[0085] Furthermore, when the bubble pump 3 is started to produce accelerated microbubbles, the pair of airflow enhancement plates 1102 in the initial state form an enhanced microspace to promote the formation of accelerated microbubbles.

[0086] When the first drive motor 2 starts to perform adsorption, multiple airflow enhancement plates 1102 flip upward under the action of the negative pressure output by the sewage extraction nozzle 1202, and a pair of airflow enhancement plates 1102 form a drainage reinforced space, that is, a reinforced space with a small upper space and a large lower space, which expands the negative pressure force of the sewage extraction nozzle 1202 and enables it to more efficiently adsorb impurities, sediments and particulate matter accumulated on the filter plate 10.

[0087] The diameter of the accelerating microbubbles is one-half to one-third of the diameter of the filter holes 1001 , so that the accelerating microbubbles can smoothly enter the multiple filter holes 1001 .

[0088] Preferably, the diameter of the accelerating microbubbles is half the diameter of the scraper 1101 .

[0089] The residual material removing device 14 includes multiple rotating balls 1401, a second driving motor 1403 and multiple connecting rods 1404, so that when the filter plate 10 is used for a long time, impurities, sediments and particles that are difficult to adsorb are easily adhered to the filter plate 10, and can be discharged under the action of the residual material removing device 14.

[0090] A first groove 1402 is formed on the rotating ball 1401 , and a limiting hole matching the plurality of rotating balls 1401 is formed on the filter plate 10 .

[0091] The filter plate 10 is located in the limiting hole and is provided with a rotating hole matching the connecting rod 1404. The connecting rod 1404 is connected to multiple rotating balls 1401, and the connecting rod 1404 is connected to the second drive motor 1403. When the residual material removing device 14 is not started, the rotating ball 1401 on the filter plate 10 is controlled by the second drive motor 1403 to rotate to the end face away from the rotating ball 1401, so that the limiting hole on the filter plate 10 is in a closed state, and the filter plate 10 can operate normally for filtering.

[0092] When it is necessary to use the cleaning component 11 to scrape off impurities, sediments and particles that are difficult to adsorb on the filter plate 10, the second drive motor 1403 can be used to control the rotating ball 1401 to rotate until the first groove 1402 is parallel to the limiting hole, that is, the first groove 1402 is located on the upper and lower end surfaces of the filter plate 10, and the scraped impurities, sediments and particles can be discharged through the first groove 1402.

[0093] The bottom end face of the filter plate 10 located in the rotating hole is fixedly connected to a waste material collection box 601, a drainage groove 603 is provided in the waste material collection box 601, and the bottom end face of the waste material collection box 601 is fixedly connected to a waste material conveying pipeline 602, which is connected to the sewage outlet 6.

[0094] The drainage trough 603 is an inclined trough, through which the scraped impurities, sediments and particles are transported to the residual material conveying pipeline 602 and discharged through the sewage outlet 6.

[0095] The filter hole 1001 is located at the top end surface of the environmentally friendly paint filter housing 101 and is provided with a pressure sensor to monitor the pressure in the filter hole 1001 in real time and to give an alarm in time when the pressure is abnormal.

[0096] The filter hole 1001 is located at the bottom end face of the environmentally friendly paint filter housing 101 and is provided with a liquid level sensor to monitor the liquid level in the filter hole 1001. When the liquid level sensor detects that the liquid level is abnormal and has not dropped, the cleaning component 11 is promptly controlled to start scraping impurities, sediments and particles on the filter plate 10.

[0097] During use, as shown in Figure 1, the paint enters the environmentally friendly paint filter housing 101 through the feed port 16 for filtration. The paint passes through the filter plate 10 by its own gravity, and the filter plate 10 is filtered through multiple filter holes 1001. At the same time, the bubble pump 3 starts to start, and the generated bubbles are transported through one of the delivery pipes 802, and the initial accelerated microbubbles are sprayed out through multiple accelerating microbubble nozzles 1302.

[0098] The initial accelerating microbubbles are formed under the action of the multiple microbubble lifting plates 1105. The accelerating microbubbles, under the action of the multiple filter holes 1001 on the contact filter plate 10, initially wrap the paint passing through the end face of the cleaning component 11, protecting the paint and preventing impurities from entering the paint. Secondly, the accelerating microbubbles generate impact force during the explosion process, increasing the pressure inside the environmentally friendly paint filter housing 101, achieving the effect of energy saving and consumption reduction. Finally, the impact force generated by the explosion of the accelerating microbubbles can impact the impurities, sediments, and particulate matter accumulated in the second cavity 1004 to the top end face of the filter plate 10, reducing the possibility of blockage in the multiple second cavities 1004 in the filter plate 10.

[0099] After being filtered by the filter plate 10 , the paint is discharged through the discharge port 5 .

[0100] As shown in Figure 8, the environmentally friendly paint filter 1 sets the running time of the cleaning component 11, so that the cleaning component 11 is started regularly to scrape the impurities, sediments and particulate matter accumulated on the filter plate 10 through the scraper 1103. While scraping, the sewage pump 4 is started, and the sewage pump 4 passes through another conveying pipeline 802, the main conveying pipeline 15 and the second sewage pipe 1201, and finally absorbs the impurities, sediments and particulate matter generated during the scraping through the sewage nozzle 1202. The airflow enhancement plate 1102 is flipped upward under the action of negative pressure, and a pair of airflow enhancement plates 1102 form a drainage reinforcement space, which expands the negative pressure force of the sewage nozzle 1202, so that it can more efficiently adsorb the impurities, sediments and particulate matter accumulated on the filter plate 10, and the impurities, sediments and particulate matter are discharged again through the sewage pump 4.

[0101] The time for the cleaning component 11 to start regularly is initially set to start every 3 to 6 hours for cleaning, and can be adjusted according to actual conditions.
