In order to prevent dust from entering the screw vacuum pump and damaging the pump body, an interception net structure is often provided inside the dust extraction pipe. The interception net needs to be cleaned when it intercepts a certain amount of dust. In the prior art, the interception net is mostly installed inside the dust extraction pipe of the sintering furnace. When the interception net needs to be cleaned, the interception net needs to be removed and a cleaning tool needs to be used to collect the dust on one side of the interception net.

The ash storage chamber 5 has a certain depth for accommodating dust in the flue gas.

[0021] A transfer assembly for quickly removing the intercepted dust is provided between the docking tube 8 and the intercepting net tube 6. The bottom of the auxiliary support plate 11 is fixedly connected to the top of the triangular plate 110. The side of the triangular plate 110 is fixedly welded to the side of the vacuum sintering furnace body 1. The triangular plate 110 improves the connection strength between the auxiliary support plate 11 and the vacuum sintering furnace body 1.

[0022] The transfer assembly includes a release motor 4, a release tube 9, and a release valve 10. The top of the release motor 4 is fixedly connected to the bottom of the vertical seat 3. The top of the vertical seat 3 is fixedly connected to the bottom of the connecting U tube 2. The other end of the mounting folding rod 12 is fixedly provided with an arc plate 14.

[0025] In the initial state, the end of the intercepting mesh tube 6 is connected to the air inlet end of the vacuum pump, and the ash storage chamber 5 is at the bottom of one end of the connecting U-tube 2. The vacuum pump extracts the flue gas inside the vacuum sintering furnace body 1 through the intercepting mesh tube 6 and the connecting U-tube 2. The dust containing the flue gas is intercepted by the holes on the outer wall of the intercepting mesh tube 6, and the dust will be temporarily retained in the ash storage chamber 5. When the intercepted dust needs to be cleaned, the release motor 4 is started, and the release motor 4 drives the storage tube 7 to rotate one hundred and eighty degrees.
