[0002] During the smelting process of non-ferrous metals, a lot of slag water will be produced. In order to achieve recycling, a filter press device is required to squeeze the slag through filter plates and pressure plates to discharge the internal moisture downwards.

[0003] After searching, Chinese patent announcement number: CN220405004U discloses a filter press device for metal smelting, which connects slag water to the liquid inlet pipe and discharges it into the filter press tank. The filter plate filters the slag water, and the pressure mechanism is started to drive the pressure plate to move downward from the top of the filter press tank. The filter residue is squeezed by the pressure plate and the filter plate to filter out the water entrained in the filter residue. The filtrate drips through the filter plate and drips on the guide plate below, and then is discharged from the drain pipe to complete the recycling of the filtrate. After a single filter press, the device only needs to pull out the filter press frame, and the inner wall of the filter press tank scrapes the filter cake on the top of the filter plate. The filter cake will fall to the bottom of the filter press tank, and then the filter press frame is pushed back into the filter press tank to perform a second filter press. The filter cake can be quickly and conveniently removed through this structure, which is conducive to continuous filter press.

[0033] Reference Figure 1 - Figure 2 The top of the filter press tank 1 is fixedly connected with a hydraulic cylinder 2, and the output end of the hydraulic cylinder 2 penetrates and is slidably connected to the inner wall of the filter press tank 1, and the bottom end of the hydraulic cylinder 2 is fixedly connected with a pressing plate 3. The output end of the hydraulic cylinder 2 drives the pressing plate 3 to move downward, thereby applying pressure to the filter residue inside the filter press tank 1 to filter out the moisture carried inside the filter residue. An inlet 4 is provided on the side wall of the filter press tank 1, and a slot 41 is provided between the inlet 4 and the inner wall of the filter press tank 1, and a filter assembly 5 is arranged inside the slot 41. The inlet 4 is used for the filter assembly 5 to enter and exit the filter press tank 1, and the slot 41 is used to position and install the filter assembly 5. The filter assembly 5 is used to perform preliminary filtration of the slag water.

[0034] Reference Figure 2 - Figure 3 The filter assembly 5 includes a plug plate 51, which is inserted into the slot 41. A handle 52 is fixedly connected to the side wall of the plug plate 51. The plug plate 51 is used to be inserted into the slot 41 to support and position the filter assembly 5. The handle 52 is used to manipulate and move the plug plate 51, so as to facilitate the removal of the filter assembly 5. A collection box 53 is fixedly connected to the bottom surface of the plug plate 51. The collection box 53 is used to collect the filtrate after the filter press and filtration, and under the pressure of the pressing plate 3, a small part of the filter residue passes through the filter plate 54 and enters the collection box 53. The collection box 53 is slidably connected to the inside of the filter plate 54. The filter plate 54 is used to filter the slag water, so that the filter residue remains on the surface of the filter plate 54, and the hydraulic cylinder 2 drives the pressing plate 3 to filter the filter residue on the surface of the filter plate 54. The bottom surface of the filter plate 54 is fixedly connected with a telescopic rod 55, and the outer wall of the telescopic rod 55 is sleeved with a buffer spring 56, one end of the buffer spring 56 is fixedly connected to the inner wall of the collection box 53, and the other end of the buffer spring 56 is fixedly connected to the bottom surface of the filter plate 54. The buffer spring 56 is used to provide elastic support for the filter plate 54, and the telescopic rod 55 is used to provide positioning for the filter plate 54, so that the filter plate 54 moves downward stably after receiving the pressure of the pressing plate 3, so that the buffer spring 56 is compressed, providing a certain buffer and adaptability, and reducing the impact on the filter plate 54. The side wall of the collection box 53 is fixedly connected with a filter screen 57. The filter screen 57 is used to perform secondary filtration on the filtrate inside the collection box 53, so that the filter residue passing through the filter plate 54 is intercepted inside the collection box 53, thereby improving the quality of the filtrate.

[0035] Reference Figure 3 - Figure 4 A cleaning assembly 6 is provided on the surface of the filter plate 54. The cleaning assembly 6 is used to clean the filter screen 57 to ensure that the filter screen 57 can maintain a good working condition during use. The cleaning assembly 6 includes a mounting groove 61. The mounting groove 61 is provided on the surface of the filter plate 54. A moving plate 62 is slidably connected inside the mounting groove 61. A through hole is provided on the side wall of the moving plate 62. A guide rod 63 is slidably connected in the through hole. The end of the guide rod 63 is fixedly connected to the inner wall of the mounting groove 61. The mounting groove 61 is used to install the moving plate 62. The guide rod 63 plays a role in stabilizing and guiding the movement of the moving plate 62, so that the moving plate 62 can stably move inside the mounting groove 61.

[0036] Reference Figure 4 The movable plate 62 is elastically connected to the inner wall of the mounting groove 61 through a return spring 64. The side wall of the movable plate 62 is fixedly connected with a support plate 65. The support plate 65 penetrates and is slidably connected to the side wall of the filter plate 54. The end of the support plate 65 is fixedly connected with a scraper 66. The return spring 64 is used to provide a supporting effect for the movable plate 62, so that the scraper 66 at the end of the support plate 65 fits with the side of the filter screen 57, so that when the filter plate 54 is pressed and moves downward, the scraper 66 slides along the side wall of the filter screen 57, thereby cleaning the side of the filter screen 57.

[0037] Reference Figure 1 - Figure 2 The side wall of the filter press tank 1 is provided with a drain port 7, and a guide plate 8 is fixedly connected to the inside of the drain port 7. The drain port 7 is used to install the guide plate 8, and the filtrate is discharged from the filter press tank 1 through the guide plate 8.

[0038] Working principle: When the operation starts, the slag water is input into the filter press tank 1 through the liquid inlet pipe 11. First, the slag water is initially filtered by the filter assembly 5, and most of the filter residue is left on the filter plate 54. As the hydraulic cylinder 2 is started, the pressure plate 3 starts to move downward, exerting pressure on the filter residue on the filter plate 54, so that the water inside it is filtered out.

[0039] During the filtration process, the filter plate 54 moves downward under pressure, at which time the telescopic rod 55 provides stable positioning, and the buffer spring 56 provides necessary buffering to reduce the impact on the filter plate 54. At the same time, under the action of the return spring 64, the movable plate 62 makes the scraper 66 fit closely with the side of the filter screen 57. As the filter plate 54 moves downward, the scraper 66 slides along the side wall of the filter screen 57, cleans the filter residue attached thereto, and keeps the filter screen 57 unobstructed.

[0040] The filtrate after the filter press first enters the collection box 53, and then passes through the filter screen 57 for secondary filtration, which further improves the quality of the filtrate. Finally, the filtrate is discharged through the drain port 7, guided by the guide plate 8, and flows to the designated collection device.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
