Specific embodiment

It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further Description, but the utility model is not limited to these examples.

As shown in Figure 1, this sintering kiln includes the bracket 1 fixed on the ground, an annular is fixedly installed on bracket 1 Furnace body 2 is respectively provided with guide rail 24 on the two sides inner wall of furnace body 2, this sintering kiln includes several material loading trolleys and at least one vehicle Head, headstock and material loading trolley can be slided in furnace body 2 by guide rail, and headstock, each material loading trolley link together；Furnace body 2 Corrugated, furnace body 2 has the arch 22 that raises upward and downwardly convex recess portion 23, be provided at arch 22 in furnace body 2 The air inlet pipe 25 and exhaust pipe 26 that chamber communicates, recess portion 23 are provided with clean window.

Material to be sintered is added in material loading trolley, material loading trolley is under the pulling of headstock, along guide rail in furnace body 2 Operation, by air inlet pipe 25 and exhaust pipe 26 to taking a breath in furnace body 2, the furnace body 2 of this kiln is utilized in longitudinal corrugated Cold air density is larger, the lesser principle of high-temperature gas density, is arranged exhaust pipe 26 and air inlet pipe 25 in arch 22, air inlet can under It is sink to 2 bottom of furnace body, smooth in exhaust does not waste, moreover, air inlet pipe 25 and exhaust pipe 26 are arranged at the top of furnace body 2, is convenient for Installation and maintenance.

Waste residue in furnace body 2 is accumulated in indent, can smoothly be cleared up by clean window, without entering in furnace body 2 It is cleared up, due to frequently clearing up inside furnace body 2, needs longer 2 cooling time of furnace body, the energy and time is greatly saved, Improve efficiency.

Heating tube can be set in furnace body 2, due to the movement of material loading trolley and headstock, temperature in furnace body 2 can be accelerated Equilibrium improves product quality.

As depicted in figs. 1 and 2, material loading trolley includes a tank body 31, and the opening of the upper end opening of tank body 31, tank body 31 can Dismantling connection has an end cap 32, and the two sides of tank body 31 are fixedly installed a short axle 33 respectively, are provided in short axle 33 and match with guide rail The idler wheel 34 of conjunction.

Since furnace body 2 is corrugated, the material loading trolley in furnace body 2 pitches in the process of running, and tank body 31 is around short axle 33 rotations, are overturn and are stirred to the material in tank body 31, make its more evenly, quick sintering reaction, improve efficiency.

The bottom of tank body 31 has screw shell 35, and 35 internal screw thread of screw shell is connected with a screw rod 36, spiral shell on screw rod 36 Line is connected with the locking nut 37 being fixed on end cap 32 on tank body 31；Pass through screw rod 36 and locking between end cap 32 and tank body 31 Nut 37 realizes dismounting.
