Multifunctional automatic quenching tank overview
China Multifunctional automatic quenching tank,quenching tank,hardening tank,continuous quenching tank is a quenching tank designed and developed by Chengchi industrial furnace according to user requirements of safety, energy saving, environmental protection, multi-purpose, multi-function, intelligent, full automation and other requirements, combined with user technical requirements. Ensure that the heat treatment quenching workpiece with appropriate configuration to achieve user quenching cooling process, quenching cooling workpiece meet the technical requirements of users, and ensure that the quenching cooling workpiece meet the requirements of safety, energy saving, environmental protection. Quenching tank according to the quenching medium can be divided into quenching tank, quenching oil tank, quenching salt tank, double liquid quenching tank, continuous quenching tank, etc.
Multi-function automatic quenching tank structure
China Multifunctional automatic quenching tank,quenching tank,hardening tank,continuous quenching tank includes: Heating system, cooling (water cooling, air cooling, low temperature), circulation system, lifting mechanism, stirring convection, medium uniform flow guidance, nitrogen (carbon dioxide) fire extinguishing system, oil smoke purification, sensing system (liquid level detection, pressure monitoring, temperature monitoring) automatic temperature control system, centralized and digital control through PLC controller, And through the touch screen to achieve man-machine exchange to achieve automatic control. We also reserve Ethernet interface for users to connect multifunctional automatic quenching slots to existing industrial Ethernet through this interface to achieve a "digital factory". Users can flexibly select various functions according to the field process, which can meet the requirements of workpiece quenching and cooling under the premise of reducing the cost.
Multifunctional automatic quenching tank body
Quenching tank body
The quenching tank body is made of section steel as the skeleton, and the thickened steel plate is processed, bent and welded by manual arc welding. It has the advantages of strong and durable, especially good tolerance to salt-bearing and alkaline quenching medium. According to the characteristics of the workpiece, the size of the material frame and the situation of the production site, the quenching tank is designed into rectangle, square, round and shaped. The middle of the high temperature quenching tank is lined with 50-100mm aluminum silicate ceramic fiber insulation layer to achieve the purpose of energy saving. The tank body is coated with anti-rust primer and topcoat. The standard color is gray for the tank body, black for the foot and lifting lug, red for the transmission part and yellow for the cover shell. Users can customize the color according to their own needs.
Multi - function automatic quenching tank frame and fishing plate
According to the characteristics of the user's workpiece, the small workpiece can use the material frame, the big heavy parts can choose the fishing plate. There are handles on both sides of the material frame, and there are welding lifting lugs and lifting rings on the fishing plate, which are used to collect the oxide skin produced by quenching and the workpiece dropped in the quenching tank due to improper operation. The two sides (four corners) are fixed by the chain sling. When the quenching tank needs to be cleaned or the workpiece needs to be salvaged, the fishing disc can be lifted out of the quenching tank by the chain sling.
Multifunctional automatic quenching tank automatic tank cover/manual tank cover
The quenching tank of the automatic lifting platform is generally equipped with an automatic tank cover. When the quenching platform falls, the tank cover is automatically covered when the workpiece enters the oil, so that the flue gas is discharged from the rear exhaust pipe. The tank cover mechanism can reduce the quenching liquid sputtering and the quenching liquid steam drifting; When the quenching tank is idle, the cover of the tank can be closed to effectively prevent foreign matter and personnel from falling, and improve safety. The automatic slot cover is driven by the reducer, and the opening and closing mode can be set to automatic and manual modes; The small quenching tank is mostly manual tank cover.
Multifunctional automatic quenching tank carbon dioxide/nitrogen extinguishing device
Fire extinguishing device adopts awakening pipe line type nitrogen (carbon dioxide) fire extinguishing system. A nitrogen fire extinguishing pipe is arranged on the inside of the quenching oil tank tank, and holes are evenly cut on the fire extinguishing pipe. When the light sensor and the temperature sensor jointly detect the fire, the fire extinguishing process can be automatically started or the sound and light alarm can be switched to manually extinguish the fire. When extinguishing the fire, nitrogen (carbon dioxide) is released in the quenching tank to cover the surface of the oil to isolate oxygen to achieve the extinguishing effect. Nitrogen/carbon dioxide gas is used to extinguish the fire, which is not only safe and reliable but also does not pollute the quenching oil.
Multifunctional automatic quenching tank mixing system
Multifunctional automatic quenching tank
mixing systemChengchi industrial furnace is equipped with an insert mixing system at the upper part of the quenching tank, which is convenient for maintenance. The forced stirring system can form a convective stirring mode, so that the quenching medium in the quenching tank rolls up and down, left and right convection, good temperature uniformity in the working area.
Stirring system is mainly composed of motor, transfer triangle belt, pulley, stirring shaft, stirring propeller, triangle belt, housing and support. The quench medium can form circulating liquid flow through the deflector, the homogenizer and the deflector tank to ensure the quenching effect. Mixing motor can also use frequency conversion motor, with frequency converter, mixing speed can be adjusted according to the needs of the process.
Multifunctional automatic quenching tank cooling cycle device
Quenching tank heat exchanger
Cooling cycle device can be divided into water cooling and wind cooling, etc., mainly composed of cooling device, circulating pump, basket filter, circulating pipeline and valve. Especially for continuous or mass quenching to provide sufficient heat dissipation capacity for quenching medium, in the rated time to cool the temperature state required by the process. At the same time of cooling, the quenching medium in the tank is enhanced, which is conducive to a more uniform temperature.
The cooling cycle of quenching tank is: quenching tank - basket filter - valve - circulating pump - cooling device - quenching tank. When the cooling capacity is large, it is recommended to choose the external circulation mode, and configure the overflow tank and liquid storage tank. The cooling device includes (plate, spiral, tubular) heat exchanger, open cooling tower, refrigerator, air cooler, etc.
