Embodiment
[0035] Such as figure 1 , 2 Shown, the present invention is made up of body of heater, and the furnace lid that is fixed on the top of body of heater. In order to overcome the defect that the air volume inside the traditional furnace body cannot be effectively circulated, the present invention is provided with an upper fan with a power of 2.5kw at the upper end of the furnace cover, and a lower fan with a power of 0.5kw at the bottom of the furnace body. There is also a cooling fan on the side. At the same time, a furnace pot is fixed inside the furnace body, and an air guide tube is fixed inside the furnace tank through a support, and workpieces to be processed are placed inside the air guide tube.
[0036] When the system is running, the upper fan on the upper end of the furnace cover runs, and the gas entering the furnace body flows through the outside of the air guide tube to the inside of the air guide tube, and then is exhausted from the exhaust port. The rotation of ...

The invention discloses an intelligent control gas multi-component permeation furnace, which mainly comprises a furnace body and a furnace cover fixed on the top of the furnace body, and is characterized in that: the upper end of the furnace cover is provided with an upper fan, and the bottom and side face of the furnace body are also provided with a lower fan and a cooling fan respectively; and the upper fan, the lower fan and the cooling fan are connected with a control system which is arranged outside the furnace body. The invention also discloses a control method for the intelligent control gas multi-component permeation furnace. The upper end of the furnace body is provided with the upper fan, and the lower end of the furnace body is also provided with the lower fan, so wind in the furnace body can be effectively circulated; meanwhile, both the upper fan and the lower fan are controlled by a frequency converter, so that the wind speed can be steplessly adjusted; and by adjusting the wind speeds of the upper fan and the lower fan, best fit is achieved, so that the wind speeds of parts in the furnace body are basically the same, and the uniformity of temperature and atmosphere is ensured.
Description
technical field [0001] The invention relates to a low-temperature chemical heat treatment equipment, in particular to a gas multi-component co-infiltration furnace capable of intelligently controlling temperature, gas and circulating air volume and a control method thereof. Background technique [0002] In the process of low temperature chemical heat treatment, the gas inside the furnace body must be effectively circulated. If the gas inside the furnace body cannot be effectively circulated, it will greatly affect the quality of the processed workpiece. It has become a key factor affecting the quality of the workpiece. Especially in the current well-type furnace, because the furnace body needs to be filled with different types of workpieces frequently, and the furnace loading capacity of different types of workpieces is also different, so it is necessary to take measures for different types of workpieces and different furnace loads. Different sizes of circulating air volume...
