Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a filtering device used in a filter press for treating steel slag sewage. Background Art

[0002] Steel slag wastewater is wastewater generated during the steel manufacturing process. It is mainly composed of cooling water, steel slag, waste rubber, pickling waste liquid and other components. It contains a large amount of heavy metal ions and organic matter, which is harmful to the human body and the environment. Filter presses are usually used in the treatment of steel slag wastewater because they can effectively separate suspended matter, heavy metals and sediment in the wastewater, realize solid-liquid separation, and remove harmful substances in the wastewater, thereby achieving the purpose of purifying water quality and reducing emissions. Filter presses are widely used in steel wastewater treatment and are one of the important equipment for the steel industry to achieve wastewater recycling.

[0003] After steel slag wastewater is filtered through a filter press, solid-liquid separation is achieved, and the solid components are compressed into a dense filter cake for subsequent treatment or safe disposal, reducing land occupation and environmental pollution. However, due to the mechanical action during the extrusion process or the stickiness of the filter cake itself, the filter cake tends to adhere tightly to the filter plate and is difficult to fall off automatically. Existing filter press filtration devices often require manual intervention, using tools such as spatulas and scrapers to manually remove the filter cake or residual fine particles. This process is time-consuming and labor-intensive, resulting in increased labor intensity for workers. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that when the above-mentioned equipment is in use, the compressed filter cake is easily adhered to the filter plate during use, and manual removal using tools such as spatulas and scrapers is required, which increases the labor intensity. Therefore, a filtering device for a steel slag sewage treatment filter press is proposed.

[0024] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1, as Figures 1-5 As shown, the utility model provides a filtering device for a filter press for treating steel slag sewage, comprising a filtering mechanism 1, a vibration mechanism 2 being fixedly mounted on the top of the filtering mechanism 1;

[0027] The vibration mechanism 2 includes a mounting frame 201, and two fixing plates 202 are fixedly installed on the top of the mounting frame 201. The outer wall of each of the two fixing plates 202 is provided with a first mounting hole 203. The inner surface wall of each of the two first mounting holes 203 is fixedly inserted with a bearing 204. A rotating shaft 205 is fixedly inserted between the inner surfaces of the two bearings 204. Five cams 206 are fixedly sleeved on the outer wall of the rotating shaft 205. A driving motor 207 is fixedly connected to the outer wall of the rotating shaft 205. Five movable slots 206 are provided on the top of the mounting frame 201. 8. The inner surfaces of the five movable grooves 208 are movably inserted with movable rods 209, and the bottoms of the five movable rods 209 are fixedly connected with pressure plates 210. The outer surfaces of the five movable rods 209 are movably sleeved with second springs 211. The tops of the five movable rods 209 are fixedly installed with mounting seats 212. One side of the outer walls of the five mounting seats 212 is provided with second mounting holes 213. The inner surfaces of the five second mounting holes 213 are movably inserted with movable rods 214, and the outer surfaces of the five movable rods 214 are movably sleeved with rollers 215.

[0028] The effect achieved by the whole embodiment 1 is that when the steel slag sewage treatment is compressed into filter cake by the filter press, first, a group of filter plates 108 are separated from each other, so that the filter cake falls off naturally from the gap between the filter plates 108, then the driving motor 207 is started, the output end of the driving motor 207 drives the rotating shaft 205 to rotate, the rotation of the rotating shaft 205 in turn drives the five cams 206 to rotate synchronously, in the rotation process of the five cams 206, the protruding end of the cam 206 will in turn contact and extrude the five rollers 215, push the rollers 215 and the five moving rods 209 connected with the rollers 215 to move downward, the downward movement of the moving rod 209 drives the pressing plate 210 to vibrate or knock a group of filter plates 108, this process will compress the five second springs 211 and two groups of first springs 107 at the same time, store elastic potential energy, when the protruding end of the five cams 206 rotates away from the five rollers 215 and no longer contacts with the rollers 215, the five second springs 211 and two groups of first springs 107 release the elastic potential energy due to the compression before, push the five rollers 215 and a group of filter plates 108 to reset, with the continuous rotation of the rotating shaft 205, the above process is repeated continuously, so that a group of filter plates 108 experience periodic vibration, which helps to further shake off the filter cake debris remaining on a group of filter plates 108, so as to achieve more thorough cleaning effect, significantly reducing the labor amount of workers manually cleaning the filter plates 108.

[0029] As shown in embodiment 2, Figures 2-5 The filter mechanism 1 comprises a support frame 101, the top of the support frame 101 is fixedly installed with two slide rails 102, the outer walls of the two slide rails 102 are movably sleeved with a group of sliding frames 103, the outer walls of the two groups of sliding frames 103 are fixedly installed with moving frames 104 on one side, the outer walls of the two groups of sliding frames 103 are fixedly installed with pull rods 105 on one side, the outer walls of the two groups of sliding frames 103 are fixedly connected with sliding blocks 106 on one side, the top of the two groups of sliding blocks 106 is fixedly connected with first springs 107, the outer walls of the two groups of sliding blocks 106 are movably sleeved with filter plates 108, the outer walls of a group of filter plates 108 are provided with two sliding grooves 109, and the outer walls of the two groups of sliding blocks 106 are movably embedded in the two groups of sliding grooves 109, the outer wall of the support frame 101 is fixedly installed with a fixed end plate 110, the inner and outer walls of the support frame 101 are fixedly installed with hydraulic cylinders 111, the extension end of the hydraulic cylinder 111 is fixedly connected with a moving end plate 112, and the outer wall of the support frame 101 is fixedly connected with the inner wall of the support frame 101.

[0030] The effect achieved by the entire embodiment 2 is that, when the steel slag sewage is filtered into filter cakes by the filter press, the hydraulic cylinder 111 is first started, and the telescopic end of the hydraulic cylinder 111 drives the movable end plate 112 to move. Since two movable racks 104 are fixedly installed on the outer wall of the movable end plate 112, the movement of the movable end plate 112 will drive the two movable racks 104 to move synchronously, and the two movable racks 104 further drive the two outermost pull rods 105 to move, so that the outermost filter plate 108 can move with the movement of the movable end plate 112. The filter plates 108 are moved by the movement of the mobile frame 104 and the mobile end plate 112, and a certain distance is maintained between the filter plates 108 and the mobile end plate 112. Through the continuous movement of the mobile end plate 112, a group of filter plates 108 can be automatically and orderly unfolded, and the two groups of mobile frames 104 and the two groups of pull rods 105 are precisely matched, so that the two adjacent filter plates 108 can be temporarily separated and a certain gap is maintained, which provides enough space for the smooth falling of the filter cake. In this way, a group of filter plates 108 can be quickly and effectively unfolded, thereby realizing the rapid and automatic falling off of the filter cake and improving work efficiency.

[0031] Working principle: After the filter press compresses the slag sewage into a solid filter cake, the hydraulic cylinder 111 is immediately started, and the telescopic end of the hydraulic cylinder 111 drives the movable end plate 112 to move. During this process, the outer wall of the two sets of pull rods 105 is movably inserted into the interior of the two sets of movable frames 104, so that after the movable frame 104 moves a certain distance, the pull rod 105 can move with the movement of the movable frame 104. Through the continuous movement of the movable end plate 112, the two sets of movable frames 104 respectively drive the two sets of pull rods 105 to move. The movement of the two sets of pull rods 105 can effectively drive a set of filter plates 108 to automatically expand and form an open state with a certain spacing to facilitate the natural falling off of the filter cake. If the filter cake fails to fall off automatically and completely, the drive motor 207 is started at this time, and the output end of the drive motor 207 drives the rotating shaft 205 to rotate, thereby driving the five cams 206 to move simultaneously. As the shaft 205 rotates step by step, the convex ends of the five cams 206 contact and squeeze the five rollers 215 during the rotation process, causing the five rollers 215 and the five moving rods 209 to move downward as a whole, causing the pressure plate 210 to vibrate or knock on the filter plate group 108, and this process simultaneously compresses the five second springs and the two groups of first springs 107 211. When the convex ends of the five cams 206 disengage from the five rollers 215, the elastic potential energy released by the five second springs 211 and the two groups of first springs 107 due to compression will drive the group of filter plates 108 and the five rollers 215 to reset. As the rotating shaft 205 continues to rotate, the group of filter plates 108 is subjected to the action of periodic up and down vibration, which effectively promotes the loosening and falling off of the residual filter cake on the surface and gaps of the filter plates 108, thereby achieving complete removal of the filter cake and ensuring the continuity and efficiency of the filtration process.
