Description

Technical Field

[0001] The utility model belongs to the technical field of ore dressing equipment, and in particular relates to a plate-and-frame filter press for ore dressing. Background Art

[0002] A plate and frame filter press is a versatile solid-liquid separation device widely used in industries such as chemical, metallurgy, pharmaceuticals, dyes, food, brewing, ceramics, and environmental protection. The filter frame is the core composite component of the plate and frame filter press. The hollow space between the two filter frames forms the filter chamber. Filter material is fed through the filter chamber feed hole under pressure, and particles trapped in the filtered material form a filter cake. The filter frames are then pulled apart to discharge the residue by gravity. Existing technologies for unloading the filter cake often cause it to stick to the filter frame, requiring manual scraping, which is inefficient and detrimental to efficient production. Therefore, a plate and frame filter press is needed to address these technical issues. Utility Model Content

[0004] Preferably, the vertical telescopic rod and the horizontal telescopic rod are electric push rods or hydraulic rods.

[0005] Preferably, the two moving blocks are respectively matched with a synchronous linear module, the moving block is fixedly connected to the slider of the corresponding linear module, and the linear module is arranged on the frame.

[0006] Preferably, the bottom of the scraper is provided with two symmetrical outwardly inclined portions, which can be used to scrape the filter frames on the left and right sides.

[0007] Preferably, the inclined portion is a silica gel block to avoid damage to the filter screen when scraping the material.

[0008] The present invention also includes other components that enable the normal operation of a plate and frame filter press selected for mining, such as the plate and frame filter press control assembly, the vertical telescopic rod control assembly, the linear module control assembly, and the horizontal telescopic rod control assembly, all of which are commonly used equipment in the field and are conventional technical means in this field. In addition, devices or components not limited to these devices in the present invention, such as the linear module, hydraulic rod, plate and frame filter press, etc., all utilize conventional technical means and equipment in this field.

[0009] Working principle: After the plate and frame filter press finishes filtration, the two moving blocks move synchronously to each filter frame, the horizontal telescopic rod extends to clamp the filter frame, the moving block drives the filter frame away from the adjacent filter frame, and the filter cake is exposed and falls between the two filter frames. If there is filter cake stuck on the filter frame, the moving block drives the gantry to move to the filter frame where the filter cake is stuck, and the vertical telescopic rod drives the scraper to move downward to scrape the filter cake, making the unloading of the filter cake of the plate and frame filter press more thorough and avoiding the sticking of the filter cake.

[0010] The beneficial effects of the utility model are as follows: the overall structure is reasonable and simple, the filter frame of the plate and frame filter press can be scraped without affecting the next use, the unloading of the plate and frame filter press is more thorough, the sticking of the filter cake is avoided, the degree of automation is high, labor is reduced, and it is conducive to efficient production.
