[0035] The present invention will be further described below in conjunction with the accompanying drawings:

[0036] like Figure 1 — Fig. 9As shown, this embodiment provides a high-efficiency and energy-saving ceramic kiln, including a furnace body shell 1, an insulation layer 2, a fixed furnace wire system 3, a lifting furnace wire system 4, a gravity support system 5 and a traction system 6. A main heating chamber 12 is provided in the furnace body shell 1, and the main heating chamber 12 is used to heat the blank. A plurality of lifting chambers 13 are provided on the lower side of the furnace body shell 1. The lifting furnace wire system 4 can be lifted and installed in the lifting chamber 13. The lifting chamber 13 is used to accommodate the lifting furnace wire system 4 that can be lifted and lowered. The lifting chamber 13 and the main heating chamber 12 are covered with an insulation layer 2. The gravity support system 5 is transmission-connected with the traction system 6, and the traction system 6 is transmission-connected with the lifting furnace wire system 4. During firing, the water content of the blank on the gravity support system 5 gradually decreases, and the traction system 6 is transmission-connected with the lifting furnace wire system 4. After the gravity borne by the gravity support system 5 decreases, the gravity support system 5 gradually cannot overcome the gravity of the lifting furnace wire system 4, and the lifting furnace wire system 4 is lowered through the conduction of the traction system 6, and at the same time, the gravity support system 5 rises.

[0037] Generally speaking, the principle of the present invention is that after the billet on the gravity support system 5 is dehydrated, the downward pressure of the gravity support system 5 on the traction system 6 is reduced, so the gravitational potential energy released when the lifting wire system 4 descends is used to pull the gravity support system 5 upward through the traction system 6, thereby realizing the automatic descent of the lifting wire system 4 and ensuring uniform firing.

[0038] When loading the kiln, an anchor bolt 51 is provided at the bottom of the gravity support system 5, and the anchor bolt 51 is connected to the furnace body shell 1 at the bottom of the main heating chamber 12 through a threaded pair. When loading the kiln, first loosen the stroke of the anchor bolt 51 by half a turn. Since the anchor bolt 51 is loosened by half a turn at this time, there is no blank on the gravity support system 5 and it is still in an unloaded state, so the gravity support system 5 is bound to be pulled upward by the traction system 6, and the lifting furnace wire system 4 will drop. Please pay attention to observe the degree of descent of the lifting furnace wire system 4 during the rotation of the anchor bolt 51. Do not drop it too much to affect the loading of the kiln. Then carry out the loading of the kiln until the blank is loaded into the lifting furnace wire system 4 and is pulled upward again, and the gravity support system 5 is sufficient to overcome the gravity of the lifting furnace wire system 4. Stop the loading of the kiln.

[0039] Please note that the gravity of the gravity supporting system 5 and the billet on the gravity supporting system 5 is much greater than the gravity of the lifting furnace wire system 4. This situation is mainly achieved through the pulley group of the traction system 6 described below. The lighter gravity of the lifting furnace wire system 4 overcomes the heavier gravity of the gravity supporting system 5, and the automatic descent of the lifting furnace wire system 4 is achieved by reducing the gravity of the billet. This is the main improvement of the present application.

[0040] Please note that the lifting scheme of the lifting furnace wire system 4 provided in the above scheme realizes that all mechanisms are in the insulation layer 2, and the insulation effect will not be affected compared with the electric kiln in the prior art. Precisely because it needs to be based on the goal of not affecting the insulation effect, it is difficult to set an electric, pneumatic or hydraulic mechanism in the high-temperature insulation layer 2 to pull the lifting furnace wire system 4. Therefore, only a mechanical structure can be designed to realize the lifting of the lifting furnace wire system 4. The reason why the lifting furnace wire system 4 must be lowered after the water content drops is that if the lifting furnace wire system 4 drops in the early stage, it will lead to excessive loss of water, causing cracking of the billet.

[0041] Specifically, a furnace door 11 for closing the main heating chamber 12 is installed on the furnace body shell 1 to close the main heating chamber 12. This is the prior art and will not be described in detail here.

[0042] Specifically, the insulation layer 2 is built with refractory bricks to achieve insulation, which is a prior art and will not be described in detail here.

[0043] Specifically, the insulation layer 2 is preset with a furnace wire installation groove, and the fixed furnace wire system 3 is composed of fixed furnace wires coiled in the furnace wire installation groove, thereby realizing the heating of the main heating chamber 12. This is the prior art and will not be described in detail here.

[0044] Specifically, the lifting wire system 4 includes a lifting wire 41 and a wire slide 42. The wire slide 42 is slidably installed in the lifting chamber 13. The lifting wire 41 is installed on the wire slide 42. The wire slide 42 is transmission-connected to the traction system 6. After the gravity of the billet on the gravity support system 5 is reduced due to dehydration, the wire slide 42 and the lifting wire 41 descend due to the lack of support from the gravity support system 5.

[0045] Specifically, a push slope 52 is provided on the top of the gravity support system 5, and the push slope 52 is transmission-connected with the traction system 6. The traction system 6 is installed on the outside of the insulation layer 2 at the corresponding position on the top of the furnace body shell 1. It is worth noting that in order to reduce the friction coefficient of the push slope 52, the push slope 52 is paved with a graphite plate.

[0046] Specifically, the traction system 6 includes a push rod 61, a traction wire rope 62, a plurality of push wheels 63 and a plurality of fixed wheels 64. The top of each push rod 61 is integrally arranged and provided with a passive inclined surface. Each push wheel 63 is rotatably installed on the corresponding push rod 61. It is worth noting that in order to reduce the friction coefficient of the passive inclined surface, the passive inclined surface is also paved with a graphite plate. The passive inclined surface is adapted to the push inclined surface 52. The push rod 61 is slidably installed on the furnace body shell 1 on the upper side of the insulation layer 2. Specifically, the furnace body shell 1 is provided with a partition for installing the traction system 6 at the upper side position of the main heating chamber 12. The partition is paved with a graphite plate. The push rod 61 is slidably installed in the partition. Each fixed wheel 64 is rotatably installed in the partition. The passive inclined surface and the push inclined surface are rotatably installed in the partition. The surface 52 is slidably connected, and the two ends of the traction wire rope 62 are respectively installed on the bottom of the furnace wire slide 42 and the furnace body shell 1. In order to guide the traction wire rope 62, a guide wheel 65 is installed on the furnace body shell 1. The traction wire rope 62 passes around the guide wheel 65, each push wheel 63 and each fixed wheel 64, so that each push wheel 63 will generate two thrusts of the gravity of the lifting furnace wire system 4, which is convenient for balancing the gravity supporting system 5 and the gravity of the billet thereon. At the same time, the push rod 61 slides along the bottom of the compartment. After the billet is dehydrated, the gravity supporting system 5 is subjected to the traction force of the lifting furnace wire 41 and the furnace wire slide 42. The weight of the billet on the gravity supporting system 5 is reduced, so that the lifting furnace wire 41 and the furnace wire slide 42 will descend, providing uniform heating after dehydration.

[0047] The working method of the high-efficiency energy-saving ceramic kiln, using the high-efficiency energy-saving ceramic kiln, includes the following steps:

[0048] S1: Loading ceramics onto the gravity support system 5;

[0049] S2: starting the fixed furnace wire system 3, and the ceramic blank gradually loses weight;

[0050] S3: The gravity supporting system 5 gradually rises and drives the lifting wire system 4 to descend through the traction system 6 until the lifting wire system 4 falls into the main heating chamber 12 .

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
