Description

Technical Field

[0001] The utility model relates to the technical field of muffle furnaces, and particularly relates to a circulating lifting and fast cooling muffle furnace. Background Art

[0002] Generally, it is not recommended to open the door of a high-temperature furnace at high temperature, such as a 1650-degree high-temperature furnace, because opening the door at high temperature will cause cold air to enter, resulting in bending and cracking of the furnace chamber and heating elements. However, some experiments require the materials to be repeatedly tested at high and low temperatures. Content of the Utility Model

[0003] In view of the above technical problems, the utility model provides a circulating lifting and fast cooling muffle furnace.

[0004] A circulating lifting and fast cooling muffle furnace includes a muffle furnace. A loading platform is arranged on the muffle furnace through a lifting mechanism. A left door and a right door are arranged at the furnace opening of the muffle furnace. Left sliders and right sliders that match the transverse slide rails are respectively arranged on the left door and the right door. The loading platform is respectively connected to the left door and the right door through a left connecting rod and a right connecting rod.

[0005] The loading platform is provided with a guiding mechanism. The guiding mechanism includes two guiding slide columns arranged on both sides of the loading platform. Sliding parts that match the guiding slide columns are arranged on the loading platform.

[0006] The sliding holes of the sliding parts match the diameters of the guiding slide columns.

[0007] Auxiliary transverse slide rails are arranged on the muffle furnace. Left auxiliary sliders and right auxiliary sliders that match the auxiliary transverse slide rails are respectively arranged on the left door and the right door. The loading platform is respectively connected to the left door and the right door through an auxiliary left connecting rod and an auxiliary right connecting rod.

[0008] A blower is arranged on the muffle furnace.

[0009] The lifting mechanism adopts a cylinder, an electric push rod or a scissor lifting mechanism.

[0010] The left and right doors are controlled by connecting rods on the upper side of the loading platform. When the loading platform rises, the left door and the right door slide left and right and open under the action of the left connecting rod and the right connecting rod. When the loading platform descends, the left door and the right door move towards the middle under the action of the connecting rods, closing the furnace chamber. The cooling blower starts to make the materials cool down quickly. After cooling for a certain time, it rises again and enters the furnace chamber for heating, and so on in a cycle.

[0011] When the loading platform descends, the left door and the right door move towards the middle under the action of the connecting rods, closing the furnace chamber, which can not only prevent cold air from entering and damaging the furnace chamber and heating rods, but also reduce heat loss and energy consumption.

[0012] The operation structure is simple, occupies less space, drives the movement of two mechanisms with a push rod, maximizes cost optimization, and provides more possibilities for experiments with repeated heating and cooling. Description of the Drawings

[0013] Figure 1 is a three-dimensional structural schematic diagram of the present utility model;

[0014] Figure 2 is a schematic diagram after the feeding platform rises of the present utility model. Detailed Embodiments

[0015] The following is a detailed description of this structure with reference to the drawings:

[0016] Embodiment 1: As shown in Figure 1 , 2 , a circulating lifting and rapid cooling muffle furnace includes a muffle furnace 1. A feeding platform 9 is provided on the muffle furnace 1 through a lifting mechanism 10. A left baffle door 2 and a right furnace door 7 are provided at the furnace opening of the muffle furnace 1. A horizontal slide rail 4 is provided on the muffle furnace 1. Left sliders 5 and right sliders 6 that match the horizontal slide rail are respectively provided on the left baffle door 2 and the right furnace door 7. The feeding platform 9 is respectively connected to the left baffle door 2 and the right furnace door 7 through a left connecting rod 8 and a right connecting rod 15.

[0017] The difference between Embodiment 2 and Embodiment 1 is that: the feeding platform is provided with a guiding mechanism. The guiding mechanism includes two guiding slide columns 13 arranged on both sides of the feeding platform. The two guiding slide columns 13 are arranged on both sides of the feeding platform. A sliding member 14 that matches the guiding slide column 13 is provided on the feeding platform 9.

[0018] The difference between Embodiment 3 and Embodiment 2 is that: the diameter of the sliding hole of the sliding member 14 matches the diameter of the guiding slide column 13.

[0019] The difference between Embodiment 4 and Embodiment 3 is that: an auxiliary horizontal slide rail 11 is provided on the muffle furnace. Left auxiliary sliders and right auxiliary sliders that match the auxiliary horizontal slide rail are respectively provided on the left baffle door 2 and the right furnace door 7. The feeding platform 9 is respectively connected to the left baffle door 2 and the right furnace door 7 through an auxiliary left connecting rod and an auxiliary right connecting rod. The auxiliary horizontal slide rail, the auxiliary sliders, the auxiliary left connecting rod 12, and the auxiliary right connecting rod have the same structure as the horizontal slide rail, the sliders, the left connecting rod, and the right connecting rod respectively, and play a role in increasing the running stability.

[0020] The difference between Embodiment 5 and Embodiment 4 is that: a blower is provided on the muffle furnace.

[0021] The difference between Embodiment 6 and Embodiment 5 is that: the lifting mechanism adopts a cylinder or an electric push rod or a scissor lifting mechanism.

[0022] The difference between Example 7 and Example 6 is that the fan can be arranged inside the muffle furnace 1, and an air outlet 3 is provided inside the muffle furnace 1.

[0023] The upper side of the charging platform controls the left and right shutter doors through connecting rods. When the charging platform rises, the left and right shutter doors are translated and opened to the left and right under the action of the left connecting rod and the right connecting rod; when the charging platform descends, the left and right shutter doors move towards the middle under the action of the connecting rods to close the furnace chamber, and the cooling fan starts to rapidly cool the material. After cooling for a certain period of time, it rises again and enters the furnace chamber for heating, and so on in a cyclic manner.

[0024] When the charging platform descends, the left and right shutter doors move towards the middle under the action of the connecting rods to close the furnace chamber, which can not only prevent cold air from entering and damaging the furnace chamber and heating rods, but also reduce heat loss and energy consumption.

[0025] The operation structure is simple, occupies less space, uses one push rod to drive the movement of two mechanisms, and the cost is optimized to the maximum, providing more possibilities for the experiment of repeated heating and cooling.
