Product Description
The sand temperature modulator is used to regulate the temperature of silica sand, which can realize the two functions of cooling and heating, using the specific heat capacity of water, the heat exchanger adopts the new type of spiral fins evenly distributed on the steel tube to realize the heat exchanging of silica sand, and the thermocouple is used as the heat-sensitive element to control the temperature of the sand, which is equipped with a water tank and a pipeline system.
Sand temperature regulator: Expert in precise control of silica sand temperature - industrial-grade solution with dual-mode temperature control ±1ºC and 40% energy saving
In industries such as casting and glass manufacturing, problems such as sand agglomeration and casting pores caused by silica sand temperature fluctuations directly affect production yield and cost. The sand temperature regulator achieves breakthrough progress in silica sand temperature control accuracy of ±1ºC and energy consumption reduction of 40% through spiral fin efficient heat exchange and PID intelligent temperature control system, becoming the core equipment in the field of precision temperature control. This article deeply analyzes the equipment technical parameters, process adaptation logic and 20+ industry application data, providing enterprises with a full process guide from sand temperature detection to system integration.
1. Core technology breakthrough: spiral fin heat exchange and dual-mode temperature control system
High-efficiency heat exchanger design (in line with GB 151-2014 standard):
Spiral fin structure:
304 stainless steel base tube (Φ25×2mm) is embedded with 0.3mm thick spiral aluminum fins (pitch 8mm), and the heat exchange area is increased by 5 times;
Measured data: The silica sand-water heat transfer coefficient reaches 450W/(m³·K), which is 300% higher than the traditional light tube.
Dual process layout:
The cooling section (20-60ºC) and the heating section (80-120ºC) are independently partitioned, and the switching time is less than 3 minutes;
The modular design supports parallel expansion, with a maximum processing capacity of 50 tons/hour.
Intelligent temperature control system (accuracy ±1ºC):
K-type thermocouple array: 8 measuring points (500mm spacing) are arranged along the sand flow direction, and the temperature gradient is fed back in real time;
PID algorithm adjustment: automatically adjust the water flow (0.5-5m³/h) according to the sand flow (5-50m³/h), and the response time is less than 10 seconds;
Energy efficiency comparison data:
Temperature control method Temperature fluctuation Energy consumption (kW·h/ton sand)
Traditional steam heating ±5ºC 18.5
Sand temperature regulator ±1ºC 11.2
