Embodiment 1

[0040] A muffle furnace, such as figure 1 , figure 2 As shown, it includes a casing 1, a rotating shaft 2 driven to rotate in the shaft center of the casing 1, and at least two partitions 6 fixed on the rotating shaft 2, and the partition 6 divides the interior space of the casing 1. The cavity is divided into at least two calcining areas 5, and a shell door 10 is provided on the side wall of the shell 1, and the top end of the rotating shaft 2 passes through the shell 1 to form a manual rotating part, and the shell door 10 is an arc door, Consistent with the size of the largest calcining area 5, each calcining area 5 is guaranteed to be opened smoothly.

[0041] Each of said calcining zones 5, such as figure 2 , image 3 As shown, the fan-shaped top insulation layer 18 and the fan-shaped bottom insulation layer 19 respectively fixed on the rotating shaft 2, the first insulation layer 3 coated on the side wall of the rotating shaft 2, and the inner wall of the housing 1 a...

Embodiment 2

[0046] This embodiment introduces its preferred structure on the basis of Embodiment 1.

[0047] As a preferred method, such as Figure 4 As shown, the rotating shaft 2 is a hollow rotating shaft, and the air inlet pipe 16 and the air outlet pipe 17 connected to each of the calcination chambers 7 respectively converge in the hollow area of ​​the rotating shaft 2 to communicate with the air inlet main pipe 12 and the air outlet main pipe 13 . The hollow rotating shaft is selected and the air inlet main pipe 12 and the air outlet main pipe 13 are arranged in the hollow part, which can simplify the pipeline and make the overall structure more concise.

[0048] As a preferred manner, the air inlet main pipe 12 and the air outlet main pipe 13 are connected with control valves 21, the air inlet main pipe 12 is connected with combustible atmosphere, and the air outlet main pipe 13 is connected with ventilation equipment. The flammable atmosphere can promote calcination and improve ...

Embodiment 3

[0056] This embodiment introduces its intelligent control system on the basis of Embodiment 1 and Embodiment 2.

[0057] The intelligent control system such as Image 6 As shown, it includes a data acquisition module for collecting temperature and atmosphere in each calcination chamber 7, a main control module, a controller module and a safety alarm module for receiving the data of the data acquisition module and analyzing and processing them; the data The acquisition module is communicatively connected to the input end of the main control module, and the controller module and the safety alarm module are communicatively connected to the output end of the main control module;

[0058] The data acquisition module includes a temperature sensor and an atmosphere sensor fixed in each of the calcining chambers 7;

[0059] The main control module is a STM32F101 series single-chip microcomputer;

[0060] The controller module includes a heating wire controller, a rotating shaft cont...

Abstract

The invention discloses a muffle furnace. Through a fan ring design of a plurality of calcination areas and in combination with the design of double external heat preservation layers and internal heatpreservation layers in each calcination area, on one hand, the working efficiency and the equipment utilization efficiency are improved, and one-time multi-batch calcination experiments are carried out; and on the other hand, heat loss is reduced, and the heat preservation effect and the calcination effect of the muffle furnace are improved. In addition, in cooperation with an intelligent controlsystem, a 4G network remote control and voice control system is utilized, the use safety of equipment is improved, a data acquisition module and a main control module are combined, remote intelligentcontrol over the muffle furnace can be achieved, and meanwhile, through statistics and analysis processing of a large amount of data, service quality guarantee is provided for use of the muffle furnace.

Description

technical field [0001] The invention relates to the technical field of experimental instruments, in particular to a muffle furnace and a method for using the same. Background technique [0002] Muffle furnace is a commonly used calcination equipment, which is widely used in various industries. The traditional muffle furnace is a box-type structure. There is a refractory fiber insulation layer between the inner furnace lining and the furnace shell. There are heating rods in the upper, lower, left, and right grooves of the inner furnace lining. The door of the muffle furnace is set on one side of the box. , The inner side of the door is provided with furnace door bricks of corresponding size. With the continuous improvement and upgrading of muffle furnaces in various fields, the performance of muffle furnaces is also continuously improved, such as rapid heating and cooling systems, overflow flushing device systems, etc. However, due to the poor airtightness of the traditiona...
