A holding basket is provided at the top of the mesh belt transmission device 2 for placing multiple workpieces at the same time when in use. Cams 9 movably connected to the mesh belt transmission device 2 are rotatably installed on both sides of the holding basket. The cams 9 are arc-shaped and are used to be inserted into the mesh belt transmission device 2 to limit the left and right positions of the holding basket when in use. When the holding basket moves along the length direction of the mesh belt transmission device 2, the holding basket drives the cams 9 to move. The cams 9 rotate through the obstruction of the mesh belt transmission device 2 to prevent the cams 9 from being stuck with the mesh belt transmission device 2 to hinder the movement of the holding basket.

[0037] The air duct 3 is installed above the feed port of the furnace body 1 and is used to communicate with the external high-pressure gas delivery device to deliver high-pressure gas to the mesh belt transmission device 2;

[0038] The guide member 4 is installed at the air outlet of the air duct 3 to diffuse the air discharged from the air duct 3 and form an air curtain; it should be noted that the bottom end of the guide member 4 is flush with the top end of the feed port of the furnace body 1.

[0039] There are multiple partitions 7, and multiple partitions 7 are installed in the holding basket. The partitions 7 are mesh plates to avoid the partitions 7 from causing significant obstruction to the workpiece.

[0040] In this embodiment, a plurality of holding slots are separated in the holding basket by partitions 7, so that a plurality of workpieces can be placed in the holding basket at the same time, thereby improving the convenience of workpiece placement and the workpiece processing efficiency. The workpiece is moved to the mesh belt transmission device 2 through the holding basket, so that the cam 9 rotates downward by gravity. When the holding basket contacts the mesh belt transmission device 2, it is plugged into the mesh belt transmission device 2 to limit the left and right positions of the holding basket. At the same time, the air duct 3 blows high-pressure gas to the mesh belt transmission device 2, and the guide member 4 diffuses the gas during the movement of the gas, so that the gas blown out of the air duct 3 forms an air curtain at the feed port of the furnace body 1, so that when the workpiece moves into the furnace body 1 and passes through the air curtain, the air curtain cleans the surface of the workpiece.

[0041] Example 2

[0042] like Figure 2 As shown, the mesh belt kiln calcining furnace proposed by the present invention, compared with the first embodiment, in this embodiment, the air duct 3 includes a main pipe 31 and a branch pipe 32;

[0043] The main pipe 31 is installed on the furnace body 1 and is connected to the external high-pressure gas delivery device; there are multiple branch pipes 32, and multiple branch pipes 32 are arranged at equal distances on the side of the main pipe 31. Among them, the main pipe 31 and the branch pipe 32 are both hoses for convenient position adjustment.

[0044] In this embodiment, the main pipe 31 is connected to the external high-pressure gas delivery device, and the high-pressure gas is delivered to the mesh belt transmission device 2 through multiple branch pipes 32, so that the area of ​​the mesh belt transmission device 2 blown by the gas is larger.

[0045] Example 3

[0046] like Figure 2-3 As shown, the mesh belt kiln calcining furnace proposed by the present invention, compared with the first embodiment, in this embodiment, the guide member 4 includes a connecting frame 41, a shell 42 and a connecting head 43;

[0047] The connector 43 is plugged into the inner side of the branch pipe 32, and the number of connectors 43 and branch pipe 32 corresponds one to one;

[0048] The housing 42 is mounted at the bottom end of the connector 43, and the inner diameter of the housing 42 gradually increases from the connector 43 toward the mesh belt transmission device 2 along the height direction of the connector 43.

[0049] The connection frame 41 is mounted on the bottom ends of the plurality of housings 42 and is in communication with the plurality of housings 42 .

[0050] It should be noted that a spiral plate 44 is provided on the inner side of the connecting head 43 .

[0051] In this embodiment, the high-pressure gas discharged from the air duct 3 is transported to the shell 42 through the connecting head 43. During the transportation process, the spiral plate 44 changes the flow direction of the high-pressure gas so that it moves along the inner wall of the shell 42 and is transported vertically to the mesh belt transmission device 2 through the guide of the connecting frame 41 to clean the workpiece placed on the mesh belt transmission device 2.

[0052] Example 4

[0053] like Figure 4 As shown, the mesh belt kiln calcining furnace proposed by the present invention, compared with the first embodiment, in this embodiment, the containing basket includes a placing plate 5 and a baffle 6;

[0054] The placement plate 5 is arranged on the top of the mesh belt transmission device 2 and has ventilation holes on its surface;

[0055] The baffle 6 is installed at the edge of the upper end surface of the placement plate 5.

[0056] In an optional embodiment, a slide groove 10 is provided on both sides of the length direction of the upper end surface of the placement plate 5, and a slide bar 11 is provided on both sides of the bottom end of the baffle 6. When the placement plate 5 and the baffle 6 are in a cooperatively installed state, the slide bar 11 is accommodated in the slide groove 10, wherein the length of the slide bar 11 and the slide groove 10 are both smaller than the length of the placement plate 5 and the baffle 6, so that one end of the placement plate 5 and the baffle 6 is blocked when they are connected through the slide bar 11 and the slide groove 10.

[0057] In an optional embodiment, a plurality of slots 8 are symmetrically provided on the inner side of the baffle 6 , and the partition 7 is installed on the inner side of the slots 8 .

[0058] In this embodiment, the partition 7 is clamped to the inner side of the baffle 6 through the clamping slot 8, so that the inner side of the baffle 6 has multiple placement slots, and the workpiece is placed in the placement slot for limitation, and the slide bar 11 cooperates with the slide slot 10 to make the placement plate 5 and the baffle 6 detachable. The placement plate 5 is suitable for workpieces with different placement requirements.

[0059] In summary, when the present invention is in use, the partition plate 7 is clamped to the inner side of the baffle plate 6 through the card slot 8, so that the inner side of the baffle plate 6 has a plurality of workpiece placement slots, so that the placement of multiple workpieces does not require additional operation restrictions, and the baffle plate 6 drives the placement plate 5 to move the workpiece to the mesh belt transmission device 2. At the same time, the cam 9 rotates downward by gravity. When the placement plate 5 contacts the mesh belt transmission device 2, one end of the cam 9 is inserted into the mesh belt transmission device 2 to limit the left and right positions of the baffle plate 6. At the same time, the air duct 3 blows the high-pressure gas to the mesh belt transmission device 2, and the guide member 4 diffuses the gas during the movement of the gas, so that the air duct 3 blows out The gas forms an air curtain at the feed port of the furnace body 1, so that when the workpiece moves into the furnace body 1 and passes through the air curtain, the air curtain cleans the surface of the workpiece. It is connected to the external high-pressure gas delivery device through the main pipe 31, and the high-pressure gas is delivered to the shell 42 through multiple branch pipes 32 through the connector 43. During the delivery process, the spiral plate 44 changes the flow direction of the high-pressure gas so that it moves along the inner wall of the shell 42, and is delivered vertically to the mesh belt transmission device 2 through the guide of the connecting frame 41, so that the delivered high-pressure gas forms an air curtain at the feed port of the furnace body 1, and cleans the surface of the workpiece moving into the furnace body 1.
