Problems solved by technology

However, the disadvantage of this tube furnace is that removing the exhaust gas during the sintering process may cause the powder sample to form dust and be discharged together with the exhaust gas, which will not only lose the powder sample, but also cause pollution to the atmosphere.

Embodiment 1

[0027] Such as figure 1 As shown, a dust leakage prevention device includes a filter screen 4 and a first exhaust pipe 8, the filter screen 4 is fixedly arranged on the burner head of the sintering furnace, and the length of the first exhaust pipe 8 is longer than the filter screen 4. The first exhaust pipe 8 passes through the burner head of the sintering furnace and the filter screen 4 sequentially, and one end is fixed on the burner head of the sintering furnace; with the filter screen 4 and the first row After the sintering furnace head of the air pipe 8 and the sintering furnace are installed and sealed, the dust particles are blocked by the filter screen 4, which can prevent dust leakage. , the first exhaust pipe 8 can continue to exhaust, so as to avoid the clogging of the filter screen 4 and the negative pressure caused by the inability to ventilate in the sintering furnace. The filter screen 4 can be cylindrical, and the filter screen 4 can be a stainless steel filte...

Embodiment 2

[0029] Such as figure 2 As shown, a dust leakage prevention device includes a filter screen 4 , a filter screen holder 5 , a vibrating motor 7 , a first exhaust pipe 8 , a first gate valve 9 , and a cover 3 . The filter screen 4 is cylindrical, one end can be fixed on the burner of the sintering furnace, and the other end is sealed. The filter screen can be stainless steel mesh, or other high temperature resistant materials, and its mesh number is 600-1000 mesh; The filter screen frame 5 is composed of several heel frames. On the periphery of the filter screen 4, one end of the filter screen frame 5 is fixed on the burner head of the sintering furnace, which can be fixed with high temperature resistant glue, and a cover 3 is installed at the other end. The cover head 3 can be umbrella-shaped, and the filter screen holder 5 can be made of stainless steel bars. The first exhaust pipe 8 is located in the center of the entire dust leakage prevention device, one end is located on...

Embodiment 3

[0032] Like the dust leakage prevention device described in Embodiment 1, the difference in this embodiment is that the mesh number of the filter screen 4 is gradually changed in stages, and at the part close to the burner head of the sintering furnace, the mesh number of the filter screen 4 The mesh number is relatively high, and the mesh number of the filter screen 4 decreases gradually during the process of moving away from the furnace head of the sintering furnace. The gradient range of the filter screen 4 is 600-1000 mesh. Usually, the powder sample will be directly sent into the depth of the sintering furnace body. Because the particle size of the powder sample is not uniform, the rotation of the sintering furnace during high temperature heating may cause the powder sample to form dust. The dust with large particles can move a distance due to its large mass. Shorter, and the dust with small particles can move longer due to its smaller mass. If the dust particles moving t...

Abstract

The invention discloses a dust leakage preventing device for an intermittent sintering furnace. The dust leakage preventing device is characterized by comprising a filter screen and a first exhaust pipe; an end of the filter screen is fixedly arranged on a sintering furnace end, the first exhaust pipe sequentially penetrates the sintering furnace end and the filter screen, and the filter screen is provided with gaps. The invention further discloses the intermittent sintering furnace with the dust leakage preventing device. The intermittent sintering furnace comprises a sintering furnace body, the sintering furnace end and a second exhaust pipe. The second exhaust pipe is positioned on the sintering furnace end, and the sintering furnace end is used for sealing the sintering furnace body. The dust leakage preventing device and the intermittent sintering furnace have the advantages that samples in the furnace can be effectively prevented from being discharged along with gas when the powder samples are sintered in the intermittent sintering furnace, accordingly, loss of the samples due to leakage of dust formed by the powder can be prevented, air pollution further can be prevented, the dust leakage preventing device is easy and convenient to mount and easy to operate, and the like.

Description

technical field [0001] The invention relates to the field of dust leakage prevention, in particular to a dust leakage prevention device and a batch sintering furnace equipped with the device.
