Steam must be locked at a temperature of around 130 degrees Celsius. A rotary valve is installed at the feed inlet for dry materials, which must pass through a steamer, and a rotary valve is installed at the discharge outlet. Each system requires 2 rotary valves, with a conveying capacity of 30 cubic meters to 50 cubic meters per hour and a size of 800 * 800 square mouth. A cleaning port is set up for regular cleaning and maintenance. First tier brand reducers and motors are also available.　　Our factory can customize the production of rotary valves for special working conditions or imported brands such as Pingti first-line.　　Rotary valves commonly used in the paper industry include rigid rotary valves, offset rotary valves, ceramic rotary valves, titanium alloy rotary valves, etc. They are mainly used to control high concentration pulp, steam and other media, and are suitable for working conditions containing fibers, particles, easily clogged media and large conveying volumes.　　Paper and pulp preparation is the first process of the entire pulp making process, with the core purpose of processing plant fiber materials such as wood and grass into a state that meets the requirements of steaming or grinding, and making quantitative reserves. The quality of material preparation directly determines whether the subsequent cooking is uniform, the yield and quality of pulp. ‌‌　　Wood preparation:　　Storage and cleaning: After entering the factory, the logs are classified and stored, and first washed with water or steam to remove sediment, gravel, etc.　　Peeling: The logs are fed into a drum peeling machine and the bark is peeled off by rolling and rubbing against each other, with a stripping rate generally above 90%. The bark can be collected as bioenergy or soil amendment.　　Stone removal and iron removal: Wood is removed from the stones brought in through a stone trap, and then metal detectors are used to check for metal fragments such as nails to prevent damage to subsequent equipment.　　Chipping: The peeled wood segments are fed into a slicer and cut into qualified wood chips, with a length of approximately 15-30 millimeters and a thickness of 3-5 millimeters. Wood chips that are too thin are easily broken into chips, while those that are too thick make it difficult for cooking agents to penetrate and produce pulp.　　Screening and washing: Wood chips are classified by size through a vibrating screen, with larger ones being crushed and smaller ones being used as biofuels. Qualified products are then washed with water to remove surface contaminants. The screening process is the key to controlling the quality of the slurry.　　Non wood raw materials:　　Generally, grasses and grasses are cut and dusted; Bagasse is mainly used for pulp removal; Bamboo, wheat straw, reeds, etc. still need to be cut and washed to remove impurities and sediment.　　Rotary valves for papermaking industry – rigid rotary valves:　　Suitable for hard materials, block materials, and high-temperature materials.　　The impeller has good stability, smooth transition, no angle, and greater torque.　　The valve body is equipped with a cleaning port for easy cleaning of materials.　　The equipment has excellent load-bearing capacity.　　Size: DN150.DN200.DN250.DN300.DN350.DN400.DN500.DN600.DN800.DN1000.DN1200.DN1500. Or square mouth 150 * 150~1500 * 1500. or non-standard customization.　　Material: Stainless steel series, Hastelloy, Titanium alloy, Wear resistant alloy series, Ceramic, Tungsten carbide, Wear resistant 400. Wear resistant 500. etc.　　Common working conditions of rotary valves in the paper industry:　　Wear resistance and anti blocking ability: Pulp contains fibers and hard particles, and valve internals should be coated with wear-resistant alloys or ceramic coatings. The flow channel should be straight to reduce slurry sticking.　　Corrosion resistance: The bleaching section comes into contact with chlorine gas, acid and alkali media, and can be made of materials such as duplex steel and Hastelloy alloy.　　Sealing and adjustability: sealing and gas locking performance; Capable of cutting fibers, suitable for adjusting pulp.　　Working condition matching: Determine the valve body material, sealing form, and actuator type based on the medium concentration, temperature, pressure, and corrosiveness.　　Partial customer requirements:　　DN600. Explosion proof grade Exdb IICT4 Gb/Extb IIIC T135 ℃ Db. Material: wood chips and powder, production capacity 7.5t/h, size DN700. material stainless steel, reducer manufacturers: SEW, Flender NORD、 Guomao, Tongli, Hengchi or domestic first-line brand products. Explosion proof motors from Wolong Electric Group’s Nanyang explosion-proof brand or Jiamusi brand or equivalent quality products.　　The VST series of a certain German brand provided by the customer is 450×810 mm, with a conveying capacity of 3 * 5 wood chips and a discharge capacity of 10m3/h. It is exported abroad with their product equipment.　　Model benchmark for Czech Haveko: ZRS500 heavy-duty external bearing rotary discharge valve, flow rate: 141m ³/h (100% filling rate); Drive: 3KW reduction motor, operating speed of 25r/min, rated at 33r/min; Explosion proof requirement: Dust explosion-proof with a surface temperature of 150 ℃ (domestic DIP A21 TA150 ℃); Whole machine weight: about 650kg, thickened wear-resistant shell, wear-resistant impeller lining; Operating conditions: Pneumatic conveying for dust removal of wood powder/sawdust, ambient temperature -20~40 ℃.　　Arch breaker+rotary valve, material: sawdust, DN300. A 3-cubic-meter silo is used, with a bottom taper of 50 ° and a length of approximately 1.3m. If there is a bridging problem and the material cannot be unloaded, a scraper and arch breaker are needed, DN300. Material: 304 stainless steel, equipped with a rotary valve below the arch breaker for uniform and quantitative feeding.　　Paper industry:　　Environmentally friendly packaging paper, high-end all wood pulp paper and its upstream and downstream industrial chain paper products, including kraft paper, environmentally friendly kraft paper, white faced kraft paper, coated kraft paper, white paper, high-strength corrugated core paper, coated gray bottom whiteboard paper, cultural paper, specialty paper and pulp products.　　High end cultural paper, high-end packaging paper, high-end household paper, high-end specialty paper, and specialty fiber dissolving pulp.　　Changzhou Tongqi Machinery Factory/Jiangsu Tongqi Technology has a professional team with over 20 years of experience in customization, design, research and development, and production. We provide professional design, material selection, and guidance to tailor integrated conveying equipment for different operating conditions.
