Description

Technical Field

[0001] The utility model belongs to the technical field of yellow iron oxide production devices, and more specifically relates to a discharge device for producing yellow iron oxide. Background Art

[0002] Iron oxide pigments are produced using the "wet sulfate" oxidation method with ferrous sulfate, iron sheets, and liquid caustic soda as the main raw materials. The entire oxidation process is a three-phase reaction of gas, liquid, and solid. The above reaction is usually carried out in an oxidation barrel, and after the reaction, the material needs to be discharged from the oxidation barrel. However, during the discharge process, the unreacted iron sheet will enter the next process through the discharge pipe, and the materials discharged in the initial stage are unevenly mixed, so it is urgent to improve it.

[0005] Preferably, the detachable filter assembly comprises a filter cartridge obliquely arranged on the transverse tube, a filter element is inserted and removed in the filter cartridge, and a filter cartridge cover is threadedly connected to the top end of the filter cartridge, which helps to regularly remove the filter element for cleaning and maintenance.

[0006] Preferably, the filter element is a cylindrical filter element made of stainless steel mesh, which has a long service life and is easy to clean.

[0007] Preferably, the barrel body of the oxidation barrel is cylindrical, and the outlet of the circulation pipe is arranged along the tangent direction of the barrel body, which helps to generate swirl of the material in the barrel body, thereby flushing the inner wall of the barrel body to prevent the material from adhering to the inner wall of the barrel body.

[0009] The working principle of the utility model is: before discharging the material in the device, first open the stop valve and the return valve and close the discharge valve, turn on the suction pump, so that the material in the conical discharge hopper is filtered by the detachable filter component and then re-enters the oxidation barrel along the circulation pipe, so that the material is fully mixed before discharging, thereby improving the uniformity of material mixing. After the material circulates for 2 to 3 minutes, close the return valve, open the discharge valve, and start discharging, thereby ensuring the uniformity of material mixing. Through the setting of the detachable filter component, it can effectively prevent the unreacted iron scraps from entering the next process, which is helpful to improve the production quality of yellow iron oxide.
