2. Project Overview

Signing date: 2022-07-18

Product name: Drying kiln

Processing capacity: 10-15t/h

Equipment configuration: φ3.5×14m drying kiln

This project deeply dries the waste salt residue produced by a drying kiln. It has the characteristics of good drying effect, large production capacity, high operating rate, low energy consumption, stable and reliable operation, and easy operation and maintenance. It can achieve energy saving, Consumption reduction and environmentally friendly production.

3. Product advantages

1. Main drive motor: It adopts variable frequency speed regulation motor, which is energy-saving and environmentally friendly, and has a large speed regulation range, high efficiency, high speed regulation accuracy and stable operation;

2. Auxiliary transmission: An auxiliary transmission motor is used to ensure that the rotary kiln can still operate when the main power supply is interrupted, preventing bending and deformation of the cylinder and facilitating maintenance. It is also equipped with an electric hydraulic block brake to avoid reversal when the kiln is stopped;

3. Supporting wheel support device and supporting wheel supporting device: Double row spherical roller bearings + thrust spherical roller bearings are used to replace the traditional sliding bearing structure, which simplifies the supporting wheel structure and improves the overall operation efficiency. Reliability reduces useless power loss during cylinder operation and makes maintenance and inspection more convenient;

4. Blocking wheel device: It adopts hydraulic blocking wheel and relies on the pressure provided by the hydraulic station to push the blocking wheel and the kiln body to realize the up and down movement of the kiln without manual intervention and is fully automated;

5. Kiln head and tail sealing device: Using three layers of flexible sealing (stainless steel sealing flakes + carbon-silicon aluminum fiber composite plate + stainless steel sealing flakes) combined with a labyrinth structure seal, the air leakage rate is low, the sealing performance is better, and the reliability is higher. Moreover, it has a longer service life and is easy to replace, which can significantly reduce its maintenance costs.
