Description

Technical Field

[0001] The utility model relates to a sintering furnace. Background Art

[0002] The existing sintering furnace is an integrated machine, which includes a furnace head, a debinding area, a high-temperature area, a cooling area and a furnace tail arranged in sequence. Debinding chimneys are provided on the top of the furnace head and the debinding area. During use, due to the high temperature, the colloid in the ceramic cast sheet is discharged from the sintering furnace through the chimney, but the effect is poor. After a long period of use, the colloid will fill up the furnace head, and eventually the colloid cannot be discharged, resulting in a decline in product quality, and it is also easy to cause blockage, making the product scrapped. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a sintering furnace so that the colloid in the sintering furnace can be discharged and will not flow back into the sintering furnace.

[0005] The first exhaust mechanism includes a first horizontal exhaust pipe, a first longitudinal exhaust pipe, a first longitudinal rubber discharge pipe, a first valve and a first rubber discharge groove; the first horizontal exhaust pipe is respectively connected to the first longitudinal exhaust pipe and the first longitudinal rubber discharge pipe, the first valve is arranged on the first longitudinal exhaust pipe, and one end of the first longitudinal rubber discharge pipe extends into the first rubber discharge groove;

[0006] The second exhaust mechanism includes a second horizontal exhaust pipe, a second longitudinal exhaust pipe, a second longitudinal rubber discharge pipe, a second valve and a second rubber discharge groove; the second horizontal exhaust pipe is respectively connected to the second longitudinal exhaust pipe and the second longitudinal rubber discharge pipe, the second valve is arranged on the second longitudinal exhaust pipe, and one end of the second longitudinal rubber discharge pipe extends into the second rubber discharge groove.

[0007] Furthermore, a first manual valve is provided at one end of the first horizontal exhaust pipe, and the other end of the first horizontal exhaust pipe is connected to the burner head.

[0008] Furthermore, a second manual valve is provided at one end of the second horizontal exhaust pipe, and the other end of the second horizontal exhaust pipe is connected to the debonding area.

[0009] The advantages of the utility model are as follows: the utility model provides a sintering furnace, which enables the colloid to be discharged from the sintering furnace along the first exhaust mechanism and the second exhaust mechanism and will not flow back to the sintering furnace, and this method enables the colloid to be discharged downward into the first row of glue grooves and the second row of glue grooves, so that the pipeline will not be blocked. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The present invention will be further described below in conjunction with the embodiments with reference to the accompanying drawings.

[0012] Figure 2 It is a side view of a first exhaust mechanism or a second exhaust mechanism in a sintering furnace of the utility model. DETAILED DESCRIPTION

[0013] See also Figure 1 and Figure 2 As shown, the utility model is a sintering furnace, comprising a furnace head 1, a binder removal zone 2, a high temperature zone 3, a cooling zone 4 and a furnace tail 5 arranged in sequence; at least one first exhaust mechanism 11 is provided on one side of the furnace head 1, and at least one second exhaust mechanism 21 is provided on one side of the binder removal zone 2;

[0014] The first exhaust mechanism 11 includes a first horizontal exhaust pipe 111, a first longitudinal exhaust pipe 112, a first longitudinal rubber discharge pipe 113, a first valve 114 and a first rubber discharge groove 115; the first horizontal exhaust pipe 111 is connected to the first longitudinal exhaust pipe 112 and the first longitudinal rubber discharge pipe 113 respectively, the first valve 114 is arranged on the first longitudinal exhaust pipe 112, and one end of the first longitudinal rubber discharge pipe 113 extends into the first rubber discharge groove 115;

[0015] The second exhaust mechanism 21 includes a second horizontal exhaust pipe 211, a second longitudinal exhaust pipe 212, a second longitudinal rubber discharge pipe 213, a second valve 214 and a second rubber discharge groove 215; the second horizontal exhaust pipe 211 is respectively connected to the second longitudinal exhaust pipe 212 and the second longitudinal rubber discharge pipe 213, the second valve 214 is arranged on the second longitudinal exhaust pipe 213, and one end of the second longitudinal rubber discharge pipe 213 extends into the second rubber discharge groove 215.

[0016] In the present embodiment, preferably, a first hand valve 1111 is provided at one end of the first horizontal exhaust pipe 111, and the other end of the first horizontal exhaust pipe 111 is connected to the burner 1, and the first horizontal exhaust pipe 111 can be cleaned through the first hand valve 1111, and the internal condition of the first horizontal exhaust pipe 111 can be opened to observe.

[0017] In this embodiment, preferably, a second manual valve 2111 is provided at one end of the second horizontal exhaust pipe 211, and the other end of the second horizontal exhaust pipe 21 is connected to the degumming area 2, and the second horizontal exhaust pipe 211 can be cleaned through the second manual valve 2111, and the internal condition of the first horizontal exhaust pipe 211 can be opened to observe.

[0018] When the sintering furnace is working, the cast sheet after isostatic lamination is placed in the sintering furnace, and then the cast sheet will move in the sintering furnace. When passing through the furnace head 1, the colloid is subjected to high temperature, causing the colloid to vaporize, and then it will be discharged along the first horizontal exhaust pipe 211. Since there is hydrogen in the sintering furnace, the hydrogen will go up along the first longitudinal exhaust pipe 112, and then it can be directly ignited at the outlet of the first longitudinal exhaust pipe 112, and part of the colloid will be liquefied again, and this part will flow downward along the first longitudinal rubber discharge pipe 113 into the first rubber discharge groove 115. Water is set in the rubber discharge groove 115, and the first longitudinal rubber discharge pipe is inserted into the water surface. Similarly, the colloid passing through the rubber discharge area 2 is also discharged into the second rubber discharge groove 215, and the hydrogen is ignited through the second longitudinal exhaust pipe 212. In this way, the colloid in the cast sheet is discharged cleanly, and the discharged colloid will not flow back to the sintering furnace.
