Description

Technical Field

[0001] This utility model belongs to the field of aluminum foil production technology, and in particular relates to a rolling oil filtration device. Background Technology

[0002] With the expansion of production scale and the improvement of product quality requirements, the existing single-stack filtration system for rolling oil uses multiple filter papers for filtration at one time. Since the entire filtration system stops every time the filter paper is replaced, all the filter papers need to be replaced simultaneously.

[0003] The traditional method is to cut off the used filter paper with a shearing device, but this method is more time-consuming and labor-intensive. In addition, for the filtration system of rolling oil, diatomaceous earth is used for filtration. After filtration, a layer of diatomaceous earth will accumulate on the filter paper. Therefore, before recycling the filter paper, this layer of diatomaceous earth needs to be scraped off.

[0004] When traditional rolling oil filters are shut down for paper replacement, the replaced filter paper cannot be quickly recycled, and there is no equipment for recycling diatomaceous earth. As a result, a large amount of diatomaceous earth is scattered around the filter during the recycling process, causing workshop pollution. In addition, a large amount of diatomaceous earth adheres to the recycled filter paper, which drastically increases the earth content of the filter paper, leading to a significant increase in the cost of hazardous waste disposal and low recycling efficiency. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0031] Example

[0032] like Figure 1As shown, a rolling oil filtration device includes a filter paper unwinding assembly, a filtering assembly, and a filter paper winding assembly arranged in sequence. 3 rolls of filter paper are stored on the filter paper unwinding assembly and pass through the filtering assembly and are wound around the filter paper winding assembly.

[0033] like Figure 1 As shown, the filter paper 3 unwinding assembly includes several unwinding shafts 11 and a first mounting base 1. Several unwinding shafts 11 are rotatably mounted on the first mounting base 1. An unwinding motor is located at the rear of each unwinding shaft 11 to drive its rotation, thus enabling the unwinding operation of the filter paper 3. A second mounting base 2 is located between the filter assembly and the first mounting base 1. Several rotating rollers 21 are mounted on the second mounting base 2 to support the filter paper 3 and guide it to the position of the filter assembly.

[0034] like Figure 1 As shown, in this utility model, the filter assembly adopts existing technology, namely a plate filter. The filter assembly includes several filter boxes 4 arranged vertically, with filter paper 3 pressed and disposed between the filter boxes 4. The rolled oil plate filter removes metal particles, oxide scale, and other impurities from the oil through filter media (filter paper 3, diatomaceous earth 31, etc.), ensuring the cleanliness and stability of the rolling process. Its filter unit (i.e., filter box 4) is composed of multiple layers of stainless steel or polypropylene filter plates stacked together to form a sealed cavity. The surface of the filter plates has grooves or corrugated structures to increase the filtration area. It also has a clamping device: such as a hydraulic cylinder or a screw mechanical clamping mechanism, which provides pressure to ensure that the filter plates are clamped and sealed.

[0035] like Figure 1-9 As shown, the filter paper 3 winding assembly includes a housing 5 and a recycling bin 8. Several support rollers 51 are arranged on the side of the housing 5 near the filter assembly, and several guide rollers 6 are arranged on the side of the housing 5 away from the filter assembly. The number of support rollers 51 and guide rollers 6 is the same as the number of filter paper 3. A winding shaft 7 is arranged below the guide rollers 6, and the winding shaft 7 is located below the middle of the support rollers 51 and guide rollers 6 on the same horizontal line. The recycling bin 8 is located on the bottom side of the housing 5 and below the guide rollers 6.

[0036] A spiral feeding mechanism 81 is provided on one side of the recycling bin 8. The spiral feeding mechanism 81 is used to transport the diatomaceous earth in the recycling bin 8 upward, and then it falls from the drop pipe to the waste soil recycling bag 82 below for bagging and recycling.

[0037] In this invention, based on the existing plate filter, a filter paper unwinding assembly and a filter paper winding assembly are added. When the filter stops, several filter papers can be replaced simultaneously. Furthermore, the replaced filter paper is supported by a support roller 51, and the filter paper's orientation is changed by a guide roller 6, thereby driving the filter paper 3 and the diatomaceous earth 31 on it to achieve efficient separation. The diatomaceous earth 31 falls and is collected in a recycling bin 8, while the filter paper 3 separated from the diatomaceous earth 31 is wound up by a winding shaft 7. This allows for rapid replacement of the filter paper 3 and efficient separation of the diatomaceous earth 31 and filter paper 3, achieving classified recycling of the filter paper 3 and diatomaceous earth 31 and improving recycling efficiency.

[0038] like Figure 2-9 As shown, furthermore, the housing 5 is equipped with several spiral blades 9, which are positioned close to the guide roller 6. Utilizing the rotation of the spiral blades 9, when the guide roller 6 causes the filter paper 3 to bend and change direction, the diatomaceous earth 31 on the filter paper 3 gradually separates from the filter paper 3. Based on this, the continuous rotation of the spiral blades 9 shears the diatomaceous earth 31, achieving efficient separation between the diatomaceous earth 31 and the filter paper 3, ensuring that the filter paper 3 wound on the winding shaft 7 no longer has diatomaceous earth 31 adhering to it, thus improving recycling efficiency.

[0039] like Figure 2-9 As shown, the support roller 51, guide roller 6 and spiral blade 9 are arranged on the same horizontal plane to ensure that the filter paper 3 is always in a horizontal conveying state before the diatomite 31 and the filter paper 3 are separated, thus preventing the diatomite 31 on the filter paper 3 from falling off.

[0040] like Figure 2-9 As shown, furthermore, the helical blade 9 has a bidirectional helical structure. (Refer to...) Figure 3 When the spiral blade 9 rotates, the double spiral structure rotates, which allows the diatomaceous earth 31 on the filter paper 3 to detach while simultaneously having a tendency to move towards the center (e.g., Figure 3 The arrow indicates the feeding direction when the spiral blade 9 rotates, to prevent diatomaceous earth 31 from scattering from both sides of the recycling bin 8.

[0041] like Figure 2-9As shown, the rolling oil filtration device of this invention also includes a drive device, which comprises a motor 71 and a worm gear transmission mechanism. The motor 71 has a reduction gearbox and is detachably mounted on the side wall of the housing 5. The worm gear transmission mechanism includes a housing 72 and a worm 722 and a worm gear 721 rotatably disposed inside the housing 72. The worm 722 and the worm gear 721 are connected for transmission. The housing 72 has several connecting holes 725 and is detachably mounted on the side of the housing 5 via bolts through the connecting holes 725. Flanges 724 are provided at both ends of the worm gear 721, and adjacent worm gears 721 are connected through flanges 724. One flange 724 is connected to the output shaft of the motor 71. Each worm 722 is connected to a drive shaft 723, which is connected to the winding shaft 7 for transmission. In this way, by using one motor 71 and several worm gear mechanisms, several winding shafts 7 can be driven synchronously to achieve the winding operation of multiple filter papers 3.

[0042] Furthermore, a first pulley 73 is provided on one side of the drive shaft 723, and a second pulley 75 is provided on one side of the shaft end of the spiral blade 9. The second pulley 75 and the first pulley 73 are connected by a belt 74 for transmission. In this way, the spiral blade 9 is rotated by means of a worm gear mechanism and a belt drive mechanism. This structure is simple and compact, requiring only one motor 71 to realize the rotational movement of the winding shaft 7 and the spiral blade 9, thereby achieving the functions of scraping and winding diatomaceous earth.

[0043] Furthermore, one side of the shaft end of the spiral blade 9 is supported inside the sliding sleeve 76, which is detachably connected to the side wall of the housing 5, and the sliding sleeve 76 provides stable support for the protruding shaft end of the spiral blade 9.

[0044] Furthermore, the outer diameter of the first pulley 73 is larger than the outer diameter of the second pulley 75, meaning that the rotational speed of the first pulley 73 is less than the rotational speed of the second pulley 75. This ensures that the rotational speed of the final winding shaft 7 is lower than the rotational speed of the spiral blade 9, so that the winding shaft 7 can achieve the winding of the filter paper 3 at a relatively low speed, while the spiral blade 9 can achieve the efficient scraping of diatomaceous earth 31 on the filter paper 3 at a relatively high speed.

[0045] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
