The dewatering effect of pressure filtration is as follows: equipment model is higher, working air pressure water content is less than tdry / set hxyz-sz45 × 28 / 800 × 1000 / 0.8u5mpa24% 2

2、 Application of belt sludge dehydrator in nonferrous smelting:

       The application effect of xyz-sz60 × 25 / 1000 × 1000 / 0.8u belt sludge dehydrator in zinc hydrometallurgy is as follows: 1. Dehydration of reducing slag: it is unresponsive ZnS concentrate and monomer sulfur, with filtration temperature of 80-90 ℃, acidity ≤ 5% H2SO4, pulp liquid-solid ratio of 4-6:1, pulp proportion of 1.6-1.8, and water content of 10% – 12% after filtration. 2. Dehydration of high leaching residue: medium leaching → low acid leaching → high acid leaching. The proportion of pulp is 1.6-1.7, the filtration temperature is 65 ℃, the moisture content of the residue after filtration is 21% – 22%, the total zinc content of the residue is 8.525%, and the moisture content of the residue is 4.793%. 3. Iron slag dehydration: it is the middle leaching and re spraying iron slag. The specific gravity of the pulp is 1.65, the filtration temperature is 75 ℃, the water content of the filtered slag is 25.1%, the total zinc content of the slag is 20%, the water content of the slag is 5.46%, the iron content of the slag is 28.7%, one working cycle is 26min, and the wet slag is 1486kg. 4. Dehydration of lead silver slag: it is the middle leaching plus high temperature and high acid leaching slag. The acid content of the liquid is 80-100g / L, the filtration temperature is 60-90 ℃, the water content of the filtered slag is 22.85%, the total zinc content of the slag is 8.10%, and the dry slag can be produced by 53.74 tons per day. 5. Dehydration of arsenic iron slag: it is the second intermediate leaching slag. After the first intermediate leaching, 3 flocculants are added to the slag slurry. The slag contains 8-10% silicon, the filtration temperature is 65-75 ℃, the liquid contains 120g / L zinc sulfate, the proportion of powder pile is 1.8, the water content of the filtered slag is 32%, the total zinc content of the slag is 16%, and the water content of the slag is 5.5%. Xys-s40 × 28 / 840 × 840 / 0.8u belt type sludge dehydrator is used to treat anode sludge in wet process lead. The water content of acid water in the sludge is less than or equal to 35%, and 900kg wet slag is produced each time.

3、 Application of belt sludge dehydrator in coal industry:

       Xyz-dz22 × 28 / 800 × 1000 / 0.8 belt type sludge dehydrator is used to dehydrate 94.6% of – 200 mesh flotation clean coal. The water content of filter cake is 24-28%, and the treatment capacity is 0.28-0.35t/m2 · h. The water content of filter cake is 17-22%, and the treatment capacity is 0.3-0.4t/m2 · H. 4、 Application in wastewater treatment: three xyz-dz60 × 30 / 1000 × 1000 / 0.8 belt type sludge dehydrators are used in the 100m3 / h smelting wastewater treatment station to treat Smelting Wastewater with solid content of 2-3%, slag water content of 62-68%, and dry slag output of 200-350kg / h. The water quality is as follows: (see the table below) It can be seen from the above application results that the belt type sludge dehydrator is applied to the filtration of “fine, muddy and sticky” materials in various industries. As an excellent solid-liquid separation equipment, the belt type sludge dehydrator should be transported, developed and widely used, with a broader development prospect.
