Lifting vertical air distribution device

Abstract

The invention relates to a lifting vertical air distribution device. The device comprises a furnace body which is internally divided into a workpiece wind cavity and a hot air circulation cavity through a partition plate, the workpiece wind cavity is communicated with the upper end of the hot air circulation cavity, a wind plate is arranged in the middle of the workpiece wind cavity, a conveying mesh belt is arranged on the wind plate, a workpeice is placed on the conveyor mesh belt, a circulation air port is formed in portion, close to the lower end, of the partition plate, a hot air circulation draught fan is arranged on the outer side, close to one side of the hot air circulation cavity, of the furnace body, a drive shaft of the hot air circulation draught fan penetrates through the furnace body to be connected with a fan blade in the hot air circulation cavity, a vertical air distribution mechanism is arranged on the portion, located above the wind plate, of the workpiece wind cavity, the vertical air distribution mechanism comprises a lifting frame which is connected with a lifting drive part, and multiple vertical wind guide blades are connected to the interior of the liftingframe. According to the lifting vertical air distribution device, it can be guaranteed that wind blowing to the workpiece is perpendicular to the workpiece all the time, the lifting frame and the vertical wind guide blade are adjustable in height, workpieces of different specifications can be continuously machined, and the universality is good.

Description

technical field [0001] The invention relates to heat treatment equipment, in particular to a lifting vertical air distribution device. Background technique [0002] The three-way catalysis of automobiles includes a catalyst carrier, which has several vertical holes, and the catalyst is coated in the vertical holes. The catalyst carrier is heat-treated through an incinerator and a drying furnace. In order to ensure heat dissipation in the vertical holes, it must be To ensure that the wind is blown vertically into the vertical hole, the traditional incinerator and drying furnace are equipped with vertical air guide blades, but if the distance between the workpiece and the vertical air guide blade is far, the air after passing through the vertical air guide blade The wind will still dissipate, and there is no guarantee that the wind will always be perpendicular to the workpiece. Contents of the invention [0003] In view of the above shortcomings, the applicant has made rese...
