Through Type Curing Oven Production Line

As a professional manufacturer and supplier of filter production equipment in China, Pulan's Through Type Curing Oven Production Line adopts a rotary conveying design, making loading and unloading more convenient while meeting the required drying time of filter elements and improving production efficiency. With a production capacity of 2 m/min, it is suitable for filter elements with height ≤400mm and equipped with 40kW heating power. The equipment runs smoothly with uniform temperature distribution, effectively avoiding local overheating and damage to filter elements.

What is Through Type Curing Oven Production Line?

Through Type Curing Oven Production Line is an automatic drying equipment used for continuous drying of filter elements. It adopts a rotary drying structure, where filter elements are transported into the heating area through the conveyor system and automatically output after drying under the preset temperature. The equipment consists of a heating system (heating tubes + fan), conveying system, temperature control system, and electrical control system. It is suitable for mass production drying processes of air filter elements, featuring uniform temperature, high efficiency, and stable operation.

Core Features

1. Rotary Drying Design, Easy Loading and Unloading
The rotary structure of Through Type Curing Oven Production Line allows filter elements to pass through the heating area in an orderly manner. Operators can continuously load and unload products from the same side, reducing unnecessary movement.
2. Constant Temperature Fan, Uniform Heating
The fan forces hot air circulation to avoid uneven temperature distribution inside the oven, preventing filter element damage caused by excessive temperature differences.
3. Adjustable Temperature (Ambient~300℃)
The digital temperature controller accurately sets the drying temperature, suitable for thermal setting requirements of different filter paper materials.
4. Stepless Adjustable Working Speed
The frequency converter controls the conveyor belt speed. With a maximum production capacity of 2 m/min, the drying time can be adjusted according to different filter sizes and drying requirements.
5. Continuous Passing Type Production
Filter elements automatically enter and exit the oven without manual transfer, making it suitable for large-scale continuous production lines.
6. Powerful Heating Capacity (40kW)
The heating system provides fast temperature rising and stable heat preservation, meeting the heating requirements of continuous production.
7. Complete Safety Protection
Equipped with emergency stop switch, protective cover, and grounding protection. The manual emphasizes that maintenance should only be performed after heating components cool down, and all filter elements must be removed from the oven before shutdown to prevent fire caused by residual heat.
8. Easy Maintenance
Daily cleaning and lubrication of transmission chains and moving parts are required. Check fasteners and transmission components monthly.

Technical Parameters

Equipment Applications and Components

Application

Batch drying of air filter elements (filter element height ≤400mm).

Main Components:

Heating System: Heating tubes (total power 40kW), constant temperature circulating fan
Conveying System: Conveyor belt (adjustable speed), rotary conveying track
Temperature Control System: Digital temperature controller (ambient~300℃ adjustable), temperature sensor
Control System: Frequency converter (working speed adjustment), power switch, emergency stop switch
Auxiliary System: Safety cover, pneumatic components (if applicable), electrical cabinet

Basic Principle and Production Process Flow

Basic Principle

The heating tubes heat up to the preset temperature, while the fan circulates hot air to maintain uniform temperature inside the oven. Filter elements are transported into the heating area by the conveyor belt, dried under constant temperature conditions for the preset time, and then automatically output after completion.

Production Process:

Preheating: Turn on the heating system, set the drying temperature, and wait until the temperature reaches the preset value (displayed on the temperature controller).
Loading: Place the filter elements to be dried at the conveyor belt feeding position.
Drying: Filter elements move through the heating area with the conveyor belt, and the drying time is determined by the working speed.
Unloading: The dried filter elements are automatically discharged from the outlet and removed by operators.
Continuous Production: Continue loading new filter elements for continuous production.

Installation Notes

Install the machine on a flat, clean, and well-ventilated floor, away from flammable materials.
Keep a distance of ≥1 meter from the left, right, and rear sides, and ≥1.5 meters from the front.
Use a forklift above 1 ton for transportation.
Fix the machine and adjust the level.
Power supply: 380V/50Hz, with independent grounding. The power cable should match the machine power requirement.
Check cables, emergency stop button, and protective cover before operation.

FAQ

Q1: What should I do if the temperature rises slowly or cannot reach the set value?
A: Check whether the heating tubes are damaged (some parts not heating), whether the temperature controller settings are correct, and whether the fan is operating normally. Replace aging heating tubes if necessary.
Q2: Why do filter elements become locally burnt or deformed after drying?
A: It may be caused by uneven temperature inside the oven or excessive temperature setting. Check whether the fan is working properly to ensure hot air circulation. Reduce the temperature setting or increase conveyor speed if needed.
Q3: What should I do if the conveyor belt does not run or the speed is unstable?
A: Check the frequency converter parameters, power supply, motor condition, and whether the conveyor belt is too loose or blocked. Adjust the frequency converter knob to check speed changes.
Q4: What should be done before finishing each shift?
A: All filter elements inside the Through Type Curing Oven Production Line must be removed and the power supply must be turned off. Remaining filter elements inside the oven may cause burning due to long-term heating from residual temperature.
