Problems solved by technology

[0003] Since the initial discharge of chemical gypsum is in the form of sand powder or mud with high water content and fluctuations easily, direct drying will cause equipment congestion, corrosion and a large amount of energy waste, so it must be homogenized and filtered before it can be processed. one step process
At present, it is not feasible to use chemical gypsum to naturally remove adsorbed water through drying sheds. Commonly used filtration equipment, such as vacuum belt filters, plate and frame filter presses, etc., only have the effect of

Example Embodiment

[0031] Example 1, such as Figure 1-4 As shown, this embodiment provides a homogenization filter device for chemical gypsum, which includes four kiln roads 8 arranged in a row, and a filter collection device connected to the bottom of each kiln road 8 is located in the filter water collection device The filter layer and the vacuum pump 6 connected with the filter water collection device; the filter layer includes an upper orifice filter layer 4 and a lower filter cloth filter layer 5.

[0032] The above device is a gypsum filtering device; gypsum is added to the stacking area in the kiln tunnel 8 from the inlet and outlet channels, and the gypsum is filtered through the orifice filter layer 4 and the filter cloth filter layer 5 in the water filter collection device at the bottom of the kiln tunnel 8. The plate filter layer 4 realizes the preliminary filtration, and the filter cloth filter layer 5 realizes the secondary filtration. The filtered water flows into the collection box ...

Example Embodiment

[0039] Embodiment 2. This embodiment provides a homogenization filtration method of a homogenization filtration device for chemical gypsum, including the following steps:

[0040] 1) Feeding: Gypsum is evenly added to the stacking area in the kiln tunnel from the inlet and outlet channels;

[0041] 2) Filtration: The gypsum is filtered through the orifice filter layer and the filter cloth filter layer in the filter box at the bottom of the kiln tunnel, and the filtered water flows into the collecting tank through the collection box for collection; the gypsum is initially filtered through the orifice filter layer. The cloth filter layer is used for secondary filtration, with high filtration efficiency and good product quality;

[0042] 3) Homogenization discharging: The filtered gypsum passes through the grab hopper on the top of the kiln road to grab the materials in the kiln road at multiple points according to the set program sequence, and enters the storage hopper of the productio...

Abstract

The invention discloses homogenization and filtration equipment for chemical gypsum. The homogenization and filtration equipment comprises at least one kiln duct, filtration water collection devices,filter layers and vacuum pumps, wherein the kiln ducts are arranged in parallel, the filtration water collection devices are located at the bottoms of the kiln ducts and communicate with the kiln ducts, the filter layers are located in the filtration water collection devices, and the vacuum pumps are connected to the filtration water collection devices; and each filter layer comprises an upper pore plate filter layer and a lower filter cloth filter layer. The invention further discloses a homogenization and filtration method. According to the equipment and the method, large-scale production ofthe high-moisture chemical gypsum can be realized, and the production energy consumption can be effectively reduced; and after the high-moisture chemical gypsum is subjected to homogenization and filtration, the quality (grade and adsorption water) of the chemical gypsum is more stable, the adsorbed water is effectively reduced by 50-60%, the filtering is uniform, the filtering effect is good, the filtering efficiency is high, the quality of filtered gypsum products is stable, the quality is improved, and meanwhile, the quality of downstream products is ensured.

Description

technical field [0001] The invention relates to the technical field of homogenizing filtering equipment, in particular to a homogenizing filtering equipment and a homogenizing filtering method for chemical gypsum. Background technique [0002] Chemical gypsum refers to the objects with calcium sulfate as the main component in industrial by-products or emissions, collectively referred to as chemical gypsum. There are mainly desulfurized gypsum, phosphogypsum, titanium gypsum, nickel gypsum, fluorine gypsum, etc., all of which are industrial wastes. The annual discharge is as high as hundreds of millions of tons. If it is not developed and utilized in time, it will cause serious pollution to soil, water and air, and destroy the ecological environment and living conditions of human beings. Therefore, the significance of developing and utilizing chemical gypsum resources is not only that it can replace natural gypsum, but also alleviate the discharge pollution of solid waste re...
