The specific meaning of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

An intelligent energy-saving low-temperature thermosetting furnace is used for heating and curing a mold. As shown in FIG. 1, the thermosetting furnace has a preheating zone 1, a heating zone 2 and a cooling zone 3, which are connected in series, and each zone is made of a high temperature resistant heat insulating material. The preheating zone 1, the heating zone 2 and the cooling zone 3 may be arranged in a plane or stacked. In the present embodiment, the preheating zone 1, the heating zone 2 and the cooling zone 3 are stacked, wherein the preheating zone 1 is located at the lower layer, the heating zone 2 is located at the middle layer, and the cooling zone 3 is located at the upper layer. The stacked arrangement is beneficial to the circulation of gas from bottom to top. The preheating zone 1 is provided with a mold inlet, the cooling zone 3 is provided with a mold outlet, the curing mold 11 enters from the mold inlet of the preheating zone 1 under the conveying of the conveying device, passes through the heating zone 2 and then comes out from the mold outlet of the cooling zone 3, and the continuous operation of the curing mold 11 is realized.

In order to prolong the heating and cooling time, a partition layer 6 is arranged in the heating area 2 and the cooling area 3, and the partition layer 6 is used for changing the conveying flow direction of the conveying device in the heating area 2 and the cooling area 3. Correspondingly, the conveying device comprises five chain conveyors 4 and four screw lifters 5, wherein one chain conveyor 4 is arranged in the preheating zone 1, and two chain conveyors 4 are respectively arranged in the heating zone 2 and the cooling zone 3. The chain conveyors 4 are arranged in an up-and-down manner and used for horizontally conveying the curing molds 11. The four screw lifters 5 are respectively located at two ends of the upper conveyor and the lower conveyor, and are used for lifting the curing mold 11 on the lower chain conveyor 4 to the upper chain conveyor 4, so that the curing mold 11 sequentially flows through the preheating zone 1, the heating zone 2 and the cooling zone 3 according to the conveying flow direction, and preheating, heating and cooling of the curing mold 11 are continuously achieved. Obviously, such a design can prolong the heating time and cooling time of the curing mold 11, and facilitate the hot melting and curing molding of the raw material in the mold.

Two sets of heating devices are arranged in the heating zone 2. In this embodiment, the heating device is a fin heating pipe 7, a high-temperature medium is introduced into the fin heating pipe 7, and the high-temperature medium dissipates heat through fins to heat the curing mold 11 in the heating area 2. In order to increase the heat dissipation effect, a low-speed fan 8 is arranged below the fin heating pipe 7, and the low-speed fan 8 is beneficial to improving the heat dissipation effect of the fin heating pipe 7.

The heated curing mold 11 still has residual heat after entering the cooling zone 3, which would result in loss of heat energy if the residual heat is not recycled. In order to reduce the consumption of heat energy, an exhaust pipe 9 and an exhaust fan 10 are connected between the preheating zone 1 and the cooling zone 3, and the exhaust pipe 9 and the exhaust fan 10 are used for extracting residual heat air in the cooling zone 3 and conveying the residual heat air into the preheating zone 1. After the exhaust pipe 9 and the exhaust fan 10 are arranged, negative pressure can be established in the heating area 2, external cold air enters the cooling area 3 from a mold outlet under the action of the negative pressure, and the curing mold 11 is reversely cooled. In the process, the external cold air is heated by the curing mould 11, is mixed with part of hot air from the heating area 2, is conveyed by the exhaust pipe 9 and the exhaust fan 10, enters the preheating area 1, and preheats the curing mould 11 newly entering the preheating area 1. In this way, the heat energy in the cooling zone 3 can be utilized as a heat source for the preheating zone 1, and the consumption of heat energy is greatly reduced.

The details of which are not described in the prior art. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
