[0002] Galvanized sheet degreasing equipment is a special equipment used to remove grease from the surface of steel sheets during the production process of galvanized sheets. Before the galvanizing process, the steel sheets must be thoroughly degreased to remove grease, dust and other contaminants left over from the rolling process.

[0003] The degreasing equipment in the prior art will be provided with a filtering structure to purify and reuse the used degreasing liquid simultaneously during degreasing. After the degreasing liquid is filtered through the filtering structure, the filtered impurities will be left on the filtering structure. The prior art often needs to pause the degreasing equipment when cleaning the filtering structure, and take out the filtering structure for cleaning. The removal and cleaning process will cause the equipment to stop, affecting the degreasing efficiency of the galvanized sheet. Therefore, a circulating filtering structure for galvanized sheet degreasing equipment is proposed to solve the above problem. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a circulating filtration structure for galvanized sheet degreasing equipment, which has the advantages of non-stop circulating filtration, etc., and solves the problem that the prior art often needs to pause the degreasing equipment when cleaning the filtration structure, and take out the filtration structure for cleaning, which will cause the equipment to stop during the removal and cleaning process, affecting the degreasing efficiency of the galvanized sheet.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a circulation filtering structure for a galvanized sheet degreasing device, comprising a filtering mechanism arranged outside the degreasing device;

[0006] The filtering mechanism comprises an external hanging frame and a circulation filter box, wherein the external hanging frame is arranged on the outside of the degreasing device, and the circulation filter box is arranged inside the external hanging frame, and a support plate is horizontally fixed inside the circulation filter box, and a partition is arranged on the upper surface of the support plate to separate the alternate circulation filtration, and two filters are arranged inside the circulation filter box to purify and filter the degreasing liquid after use, and an injection hole is opened on the upper surface of the partition, and a bellows connected with the degreasing device is arranged inside the injection hole to guide the degreasing liquid into the filter for filtering treatment;

[0007] The filtering mechanism also includes a pull rod arranged on the right side of the partition, and the right end of the pull rod penetrates and extends to the outside of the circulation filter box and is fixed with a handle for changing the position of the partition on the support plate through the pull rod.

[0008] Furthermore, feed holes corresponding to two filters are respectively provided on the left and right sides of the upper surface of the support plate, so as to allow the degreasing liquid injected by the bellows to enter the corresponding filters.

[0009] Furthermore, guide rails are provided on both the front and rear sides of the circulation filter box, sliding grooves are provided on both the front and rear sides of the partition plate, and the partition plate is slidably connected to the outer sides of the two guide rails through the two sliding grooves.

[0010] Furthermore, the lower surface of the circulation filter box is connected to an output pipe for outputting the filtered and purified degreasing liquid to the outside for recycling.

[0011] Furthermore, the length of the partition is half of the length of the support plate, so as to ensure that the positions of the injection hole and the feed hole after the movement correspond to each other.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] 1. The circulating filtration structure for the galvanized sheet degreasing equipment has two filters inside the circulating filtration box, which can realize alternate filtration. Through the setting of the pull rod and the handle, the operator can adjust the position of the partition as needed to drive the bellows to the top of different filters, thereby controlling the degreasing liquid to flow to different filters. The bellows allows the degreasing liquid to be guided from the degreasing equipment to the filter for filtration to remove impurities and fat in the degreasing liquid. When one filter is filtering, the other can be cleaned or replaced, ensuring the continuity of the filtration process. The degreasing liquid after filtration and purification is output through the output pipe and can be recycled, reducing the consumption of the degreasing liquid.

[0014] 2. The circulating filtration structure used for the galvanized sheet degreasing equipment is designed not to leave the degreasing equipment, so it can be cleaned and maintained while the equipment is running, avoiding production interruptions caused by equipment shutdown. The continuous operation of the filtration structure reduces the start and stop times of the degreasing equipment, thereby reducing the mechanical wear and maintenance costs of the equipment. Impurities in the degreasing liquid are removed by continuous filtration, ensuring the quality of the degreasing liquid, thereby improving the degreasing effect of the galvanized sheet. The entire filtration process is carried out in a closed system, reducing potential risks to operators and the environment. The design of the circulating filtration structure makes full use of its integration, automation and flexibility, and improves the filtration efficiency and production efficiency of the degreasing liquid.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1: Please refer to Figure 1-3 In this embodiment, a circulating filtering structure for a galvanized sheet degreasing device includes a filtering mechanism 2 arranged outside the degreasing device 1.

[0021] Example 2: Please refer to Figure 2-3 On the basis of the first embodiment, in order to filter the galvanized sheet degreasing liquid in a non-stop circulation, the filtering mechanism 2 in this embodiment includes an external hanging frame 21 and a circulation filter box 22. The external hanging frame 21 is arranged on the outside of the degreasing equipment 1, and the circulation filter box 22 is arranged inside the external hanging frame 21. A support plate 23 is horizontally fixed inside the circulation filter box 22, and a partition 24 is provided on the upper surface of the support plate 23 for separating the alternating circulation filtration. Two filters 25 are provided inside the circulation filter box 22 for purifying and filtering the degreasing liquid after use. Two filters 25 are provided inside the circulation filter box 22 to achieve alternating filtration. A material injection hole is opened on the upper surface of the partition 24, and a bellows 26 connected to the degreasing equipment 1 is provided inside the material injection hole to guide the degreasing liquid into the filter 25 for filtration treatment.

[0022] The filtering mechanism 2 also includes a pull rod 27 arranged on the right side of the partition 24, and the right end of the pull rod 27 passes through and extends to the outside of the circulation filter box 22 and is fixed with a handle for driving the pull rod 27 to change the position of the partition 24 on the support plate 23.

[0023] By providing the pull rod 27 and the handle, the operator can use the pull rod 27 to adjust the position of the partition plate 24 on the support plate 23 as needed.

[0024] In this embodiment, feed holes corresponding to the two filters 25 are respectively provided on the left and right sides of the upper surface of the support plate 23, so as to allow the degreasing liquid injected by the bellows 26 to enter the corresponding filter 25. Guide rails 28 are provided on the front and rear sides of the circulation filter box 22. Slide grooves are provided on the front and rear sides of the partition 24, and the partition 24 is slidably connected to the outer sides of the two guide rails 28 through two slide grooves. The lower surface of the circulation filter box 22 is connected with an output pipe 29, so as to output the filtered and purified degreasing liquid to the outside for recycling. The length of the partition 24 is half of the length of the support plate 23, so as to ensure that the position of the injection hole after movement corresponds to the position of the feed hole.

When one filter 25 is filtering, the other is in an idle state and can be cleaned or replaced, thereby ensuring the continuity of the filtering process. The filtered and purified degreasing liquid is output through the output pipe 29 for recycling.

[0025] It should be noted that the partition 24 moves on the outside of the guide rail 28 through the slide groove to keep the partition 24 moving smoothly and close to the surface of the support plate 23, so as to drive the bellows 26 to the top of different filters 25, thereby controlling the degreasing liquid to flow to different filters 25, which can further avoid the leakage of the degreasing liquid.

[0026] The working principle of the above embodiment is:

[0027] When the galvanized sheet degreasing liquid is used for non-stop circulation filtering, two filters 25 are arranged inside the circulation filter box 22 to realize alternating filtering. Through the setting of the pull rod 27 and the handle, the operator can adjust the position of the partition 24 on the support plate 23 by the pull rod 27 as needed. The partition 24 moves on the outside of the guide rail 28 through the slide groove to keep the partition 24 moving smoothly and close to the surface of the support plate 23, so as to drive the bellows 26 to the top of different filters 25, thereby controlling the degreasing liquid to flow to different filters 25. The bellows 26 allows the degreasing liquid to be guided from the degreasing equipment 1 to the filter 25 for filtration. The filter 25 purifies and filters the injected degreasing liquid to remove impurities and fat in the degreasing liquid. When one filter 25 is filtering, the other is in an idle state and can be cleaned or replaced, thereby ensuring the continuity of the filtration process. The filtered and purified degreasing liquid is output through the output pipe 29 for recycling.
