PTFE Lined Chemical Production Mixing Vessel

PTFE Lined Chemical Production Mixing Vessel is dedicated batch-type blending equipment, functionally different from reaction kettles for chemical synthesis and simple receiving buffer tanks. Its primary task is homogenizing multi-component corrosive liquids, dissolving solid additives and preparing premixed working fluids, rather than driving complex chemical synthesis reactions. Both tank cavity and full stirring assembly are protected by integrated PTFE lining to prevent medium contamination and metal erosion. Optional jacket structure realizes temperature control during mixing cycles. It can be combined with lined pipeline, tee and valves to constitute closed corrosive-liquid batching loops, widely used for continuous batching operations in overseas chemical industrial plants.

What is PTFE Lined Chemical Production Mixing Vessel

PTFE Lined Chemical Production Mixing Vessel is pressure-capable batch-blending vessel composed of Q245R carbon-steel outer shell, seamless vacuum-laminated PTFE inner lining and complete PTFE-wrapped stirring unit. Its core mission is physical homogenization work: liquid blending, solid dissolving, slurry preparation and premixing of corrosive raw-materials, not for high-intensity chemical synthesis. Tank interior, shaft and impeller achieve full fluorine-material coverage without exposed metal. It supports jacket-type heating or cooling for constant-temperature mixing. Multiple reserved nozzles are set for feeding, discharging, sampling and liquid-level monitoring. It connects to peripheral anti-corrosion pipe fittings via HG20536 full-PTFE-lined flanges and forms a closed batching production unit.

Core Product Advantages

1. Full-Set Lined Mixing Assembly Not only tank inner wall; agitator shaft and impeller are entirely wrapped by PTFE material. Avoid galvanic corrosion caused by bare metal stirring parts contacting aggressive chemicals during high-speed blending.

2. Optional Jacket Temperature-Control Structure Integrated outer jacket supports steam heating or coolant circulation, keeping stable temperature while dissolving and mixing corrosive components, adapting temperature-sensitive batching workflows.

3. Multi-Impeller Solution For Different Viscosity Supply propeller, anchor-type, turbine-style PTFE-lined impellers, matching low-viscosity liquid blending, solid dissolving and high-viscosity slurry-mixing separately.

4. Low-Residue Smooth Inner Surface Smooth PTFE lining reduces material adhesion. Convenient inner-tank flushing when switching different-formula batches and lowers cross-contamination risk.

5. Adapt Batch & Semi-Continuous Production Modes Suitable for intermittent batch batching and semi-continuous circulating premixing. No complex reaction-related configuration, focusing on blending efficiency for chemical-plant daily material preparation.

6. Unified Anti-Corrosion Flange Compatibility HG20536 standard full-lined flanges, seamless docking with Zhuoyan full-series lined pipeline, tee, valve and storage-tank for whole-batching-system one-stop procurement.

Professional Model Selection Suggestions

1. Volume matching based on batch output Small-batch workshop batching: choose 100-800L; mass-production chemical-plant premixing: adopt 1500-5000L vessel. Effective working liquid level shall occupy 60-80 % of total tank volume for ideal mixing performance.

2. Select impeller according to material viscosity & state Low-viscosity pure-liquid blending: select propeller impeller; solid-dissolving & medium-viscosity material: turbine impeller; high-viscosity slurry: anchor-type impeller.

3. Lining-thickness judging by medium property Common acid-alkali liquid: adopt standard 2 mm lining; fluorine-containing slurry with particle scouring: upgrade to 3 mm thickened PTFE lining.

4. Jacket-structure confirmation If mixing process needs heating or cooling, select jacket-equipped version; ordinary room-temperature blending can omit jacket to control investment cost.

5. Working condition feedback for stirring parameters Provide medium viscosity, solid-content ratio and target mixing time. Our technical team optimizes stirring power and rotating speed to avoid insufficient homogenization or ineffective energy consumption.

6. Pipeline docking requirement Offer drawing parameters of peripheral lined pipe fittings, we adjust nozzle quantity and position for direct on-site assembly without secondary modification.

Exclusive QC Inspection Flow For Mixing Vessel

1. Tank-shell processing: Weld polishing and burr removal; 500 ℃ high-temperature degreasing to eliminate welding residual stress.

2. Inner-wall Sa2.5 heavy sandblasting treatment to guarantee adhesive strength for PTFE sheet.

3. Sodium-activation raw-material treatment; vacuum seamless lamination inside 10 000-grade clean workshop. Execute double PFA hot-melt welding for nozzle corner positions.

4. Independent lining production for agitator shaft and impeller, strictly inspect for pinholes or local thin spots on stirring components.

5. Full-wall mobile 10 KV spark scanning inspection, specially check transition zones of tank-nozzle and agitator assembly.

6. Hydraulic pressure holding test at 1.2-times design pressure, keep pressure 30 minutes without pressure drop.

7. Complete mechanical assembly of motor, reducer and PTFE-lined agitator; carry out no-load & simulated-load dynamic stirring running test to verify rotation stability and sealing performance.

8. Inner-cavity cleaning; all flanges and shaft-passing openings are sealed with dedicated PTFE protective caps before reinforced export-oriented packaging.

FAQ

Q1: What kind of working scenarios is this PTFE Lined Chemical Production Mixing Vessel suitable for?

A: It targets physical batching work including corrosive-liquid blending, solid dissolving and slurry premixing, not designed for complex high-intensity chemical synthesis reactions.

Q2: How to choose the correct impeller type for my material?

A: Low-viscosity liquid for propeller; solid-dissolving for turbine; high-viscosity slurry for anchor-style impeller. You may provide medium viscosity and solid-content for our technical recommendation.

Q3: Can this mixing vessel be equipped with heating-cooling jacket?

A: Yes, jacket-type temperature-control structure is optional for constant-temperature mixing workflows. Room-temperature batching can omit jacket to reduce cost.

Q4: Are stirring shaft and impeller also fully protected by PTFE lining?

A: Agitator shaft and impeller adopt independent full PTFE lining, preventing corrosion of rotating parts under corrosive-medium mixing environment.

Q5: What special inspections will each mixing vessel pass before delivery?

A: Every unit undergoes spark leakage scanning, hydraulic tightness test, plus dynamic stirring running test for assembly and sealing-performance verification.

Q6: What is the official warranty scope?

A: Carbon-steel shell enjoys 10-year structural warranty; PTFE lining 5-year warranty (exclude artificial scratch and mis-operation damage); stirring motor-reducer accessories 2-year warranty.
