Description

Technical Field

[0001] The invention relates to the technical field of filtering devices, in particular to a cold-rolled emulsion filtering device. Background Art

[0002] Cold rolling emulsion is a cooling lubricant specially used in cold rolling production lines. It is mainly used in the processing of cold rolled steel plates to cool the rolls, reduce rolling force, reduce friction coefficient, improve the surface quality of the plates, and protect the rolls and rolling equipment. In cold rolling workshops, emulsions are used in large quantities and are an indispensable medium in cold rolling production lines.

[0003] During the use of cold-rolled emulsion, impurities such as debris and grinding wheel powder will be brought in. These impurities will affect the subsequent performance and use effect of the emulsion, so it needs to be filtered. The existing filtering method uses a belt vacuum filter to absorb the magnetic particle impurities in the emulsion through vacuum suction to achieve the purpose of purifying the emulsion. The impurities on the surface of the filter belt can be cleaned by a scraper knife, but a large amount of impurities will remain in the filter belt. When the filter belt is circulated and filtered, the filtering effect will gradually decrease. For this reason, we propose a cold-rolled emulsion filtration device. Summary of the invention

[0015] Compared with the prior art, the present invention provides a cold-rolled emulsion filtering device, which has the following beneficial effects: 1. Through the cooperation between the sixth spur gear and the discharge pipe, the emulsion in the discharge pipe can be centrifugally stirred before filtration, thereby accelerating the separation of the emulsion and impurities, avoiding the accumulation of impurities caused by direct current filtration, and avoiding the reduction of the filtering effect of the filter. Through the cooperation between the blade and the first slide bar, the blade can stir the coagulant to avoid the influence of deposition on the use effect. The coagulant can also be intermittently output after the third opening is aligned with the second opening to mix the emulsifier and the coagulant, thereby aggregating the fine particles into relatively large agglomerates, which is conducive to improving the filtration speed and effect. Through the mutual cooperation between the third opening and the first slide bar, the emulsifier and the coagulant are mixed, thereby gathering the fine particles into relatively large agglomerates, thereby improving the filtration speed and effect. By cooperating with each other, the coagulant can be quantitatively output, so that the emulsifier can be evenly mixed with the coagulant, and the impurities can be continuously coagulated, which helps to reduce the pollutant content in the emulsion, maintain its cleanliness, and ensure the effective use of the emulsion in the cold rolling process. Through the cooperation of the auger rod and the filter cylinder, the emulsifier can be initially filtered, and the metal debris and other larger particle impurities in the emulsifier can be filtered out. Then, the auger rod and the discharge cylinder cooperate with each other to collect the magnetic and non-magnetic impurities separately, so that the impurities can be separated and processed separately, reducing the subsequent separation steps and improving the filtration efficiency.

[0016] 2. Through the cooperation between the slider and the slide groove, the rotating shaft rotates and slides at the same time, so that the cleaning strip can scrape and clean the filter belt while moving horizontally to brush the surface of the filter belt, so that the filter belt is cleaned more comprehensively, so that the impurities in the filter belt can flow out. By cleaning the impurities on the filter belt, it can be ensured that the filter holes of the filter cloth are not blocked, thereby improving the filtration efficiency. The cleaned filter belt can better intercept solid particles and allow liquid to pass quickly, realizing efficient solid-liquid separation. Regular cleaning can prevent long-term accumulation of impurities and cause increased wear of the filter cloth, thereby extending the service life of the filter cloth.

[0017] 3. Through the cooperation between the water storage pipe and the drainage pipe, when the cleaning strip cleans the filter belt, the spray head can flush the cleaning range of the cleaning strip, so that the impurities in the filter belt are flushed outward, thereby strengthening the maintenance of the filter belt and improving the subsequent filtration efficiency. It avoids the accumulation of impurity particles inside the filter belt, which causes the filtration efficiency of the filter to decrease. It not only saves water resources, but also reduces the difficulty of operation and labor intensity, and improves work efficiency. Cleaning the filter belt helps to keep the equipment clean and stable, and reduce equipment failures and downtime caused by filter belt blockage, which ensures the continuous and stable operation of the equipment and improves production efficiency.

[0040] Working principle: when in use, the used emulsion is input to the lower feed pipe 6 through the pipeline, the motor is started to drive the drum 3 to rotate, the drum 3 drives the filter belt 4 to rotate, the lower feed pipe 6 outputs the emulsion into the filter cylinder 79, the emulsion flows downward through the filter holes of the filter cylinder 79 and is concentrated at the upper end of the filter belt 4, the scraper 9, the filter plate 10 and the mounting plate 2 block and limit the flow range of the emulsion, so that the emulsion penetrates into the filter belt 4 within the interval, the drum 3 drives the first spur gear 71 to rotate, the first spur gear 71 drives the second spur gear 73 to rotate through the first chain 72, the second spur gear 73 drives the third spur gear 74 to rotate, the third spur gear 74 drives the fourth spur gear 76 to rotate through the second chain 75, the fourth spur gear 76 drives the auger rod 77 to rotate inside the filter cylinder 79, the auger rod 77 transmits the impurities filtered by the filter cylinder 79 to the discharge cylinder 78, the magnetic particles are concentrated on the inner side of the discharge cylinder 78, and the non-magnetic impurities fall into the collection cylinder 710; The second spur gear 73 drives the first bevel gear 711 to rotate, the first bevel gear 711 drives the second bevel gear 712 to rotate, the second bevel gear 712 drives the fifth spur gear 714 to rotate through the fixed rotating shaft 713, the fifth spur gear 714 drives the sixth spur gear 716 to rotate through the third chain 715, and the sixth spur gear 716 drives the feeding pipe 6 to rotate. The centrifugal force causes the impurities of the lubricating oil in the feeding pipe 6 to concentrate on the inner wall of the feeding pipe 6, and then enter the filter cylinder 79 downward to accelerate the separation of impurities and emulsion. When the feeding pipe 6 rotates, it drives the blade 718 to stir the coagulant in the liquid storage tank 717. When the blade 718 rotates, it will touch the arc surface of the first slide bar 719 and then press the first slide bar 719, so that the first slide bar 719 slides into the second slide bar 722 and presses the third opening 723, The coagulant enters the first slide bar 719 through the first opening 720, and then the first slide bar 719 slides to align the second opening 721 with the third opening 723, and the coagulant flows out from the second opening 721 to the third opening 723, and then drips onto the lubricating oil on the upper end of the filter belt 4 to mix, and after the blade 718 and the first slide bar 719 are staggered, the first slide bar 719 is reset when the first spring 724 is opened, and the second opening 721 and the third opening 723 are staggered to stop outputting the coagulant, and the emulsion is decomposed by the coagulant and decomposed with finer impurities, and then sinks into the vacuum box 11 after passing through the filter belt 4, and then the vacuum generator 13 is started to use the negative pressure of the vacuum to collect the emulsion filtered by the filter belt 4 in the vacuum generator 13 through the recovery pipe 12, and then it is collected in the recovery tank 14; After being filtered, the impurities in the filter belt 4 form a filter cake on the inner side and the upper end of the filter belt 4, and move with the filter belt 4. The third spur gear 74 drives the seventh spur gear 81 to rotate, and the seventh spur gear 81 drives the eighth spur gear 83 to rotate through the fourth chain 82. The eighth spur gear 83 drives the first sleeve 84 to rotate, and the first sleeve 84 drives the slider 85 to rotate. When the slider 85 rotates, the bevel design of the slide groove 87 allows the rotating shaft 86 to slide on the inner side of the first sleeve 84 when it rotates, so that the slide groove 87 drives the water storage pipe 88 to rotate and slide, and the water storage pipe 88 drives the drain pipe 89 to rotate, and the drain pipe 89 drives the spray head 814 and the cleaning strip 816 to rotate. After the cleaning strip 816 contacts the filter belt 4, it is subjected to pressure to drive the pressing block 812 to slide toward the inner side of the second sleeve 815, and compress the second spring 813, and then the drain pipe 89 slides toward the inner side of the water storage pipe 88, and the drainage hole 811 enters the inner side of the water storage pipe 88. The water source passes through the drainage hole 81 1 enters the drain pipe 89, and then uses the spray head 814 to spray the filter belt 4. The spray head 814 is a symmetrical L-shaped design that can be staggered with the cleaning strip 816. When the cleaning strip 816 is cleaning, it can spray the cleaning area comprehensively. The tension of the second spring 813 makes the cleaning strip 816 close to the filter belt 4, scrapes one side of the filter belt 4, and squeezes out the impurities inside the filter belt 4. Then, the water storage pipe 88 is used to rotate and slide to drive the cleaning strip 816 to fit the filter belt 4. When it can be scraped, it can be moved horizontally for cleaning, so that the cleaning is more comprehensive and dead corners are avoided. After the cleaning strip 816 is staggered with the filter belt 4, the second spring 813 is opened, so that the drain pipe 89 drives the drainage hole 811 to separate from the inner side of the water storage pipe 88, and the position is limited by the limit block 810. The spray head 814 stops outputting water flow, and another set of cleaning strips 816 are in contact with the filter belt 4 to clean again, thereby saving water and reducing resource waste.
