DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 The utility model provides an embodiment: a highly sealed shuttle kiln, comprising a shuttle kiln shell 1 and brackets 4 fixed on both sides of the bottom of the shuttle kiln shell 1, a kiln liner body 3 is installed inside the shuttle kiln shell 1, a kiln door 2 is installed on one side of the surface of the shuttle kiln shell 1 through a hinge, an I-shaped cross arm 5 is installed on the outer wall of the bracket 4 on one side close to the vertical center reference plane of the shuttle kiln shell 1, and a supporting structure is installed on the top of the I-shaped cross arm 5, an I-shaped rail 7 is installed on the top of the supporting structure, a trolley 303 is installed on the top of the I-shaped rail 7 through a sliding support structure, and an electric drive mechanism for driving the trolley 303 to move in and out of the shuttle kiln shell 1 is installed on the top of the I-shaped cross arm 5;

[0021] Rectangular ribs are arranged on both sides of the bottom of the kiln inner tank body 3, and straight lower grooves that slide with the rectangular ribs are arranged on both sides of the top of the trolley 303;

[0022] The supporting structure is an I-shaped longitudinal arm 6 fixed to the top of the I-shaped cross arm 5, the top of the I-shaped longitudinal arm 6 is fixedly connected to the bottom of the I-shaped rail 7, both sides of the bottom of the I-shaped cross arm 5 are installed with right-angle seats, both sides of the bottom of the right-angle seat are installed with bolts, the top of the bolts extend to the inside of the I-shaped longitudinal arm 6, and the bolts are used to improve the connection strength of the I-shaped cross arm 5 and the I-shaped longitudinal arm 6;

[0023] The sliding support structure is a steel wheel 302 installed on the two inner walls of the inverted U-shaped protrusion 301. When the kiln inner tank body 3 moves in the extending direction of the I-shaped longitudinal arm 6, the inverted U-shaped protrusion 301 generates rolling friction with the outer wall of the I-shaped track 7 through the steel wheel 302, thereby reducing the sliding instability factor of the inverted trolley 303, which helps to ensure the accuracy and safety of the operation;

[0024] The I-shaped longitudinal arm 6 and the I-shaped rail 7 are of equal length, and the I-shaped cross arm 5, the I-shaped longitudinal arm 6 and the I-shaped rail 7 are all made of alloy steel;

[0025] Alloy steel has excellent wear resistance and can resist surface wear caused by friction and abrasion. During the operation of the trolley 303, the I-shaped cross arm 5, the I-shaped longitudinal arm 6 and the I-shaped rail 7 often need to undergo repeated friction and movement. The use of alloy steel can extend their service life and reduce the frequency of maintenance and replacement.

[0026] The electric drive mechanism includes an inverted U-shaped protrusion 301 installed on both sides of the bottom end of the trolley 303, and a rack transfer structure 9 fixed on the outer wall of one side of the inverted U-shaped protrusion 301. The top of the I-shaped cross arm 5 is rotatably installed with a vertical shaft 8, and the other side of the top of the I-shaped cross arm 5 is installed with a rotation drive unit 10 for driving the vertical shaft 8 to rotate. The vertical shaft 8 is driven by the rotation drive unit 10 to rotate, so that the rack transfer structure 9, the trolley 303 and other components are driven by the vertical shaft 8 to move in the extension direction of the I-shaped longitudinal arm 6 and the I-shaped rail 7 until the trolley 303 is completely sent into the shuttle kiln shell 1. At this time, the bottom end of the kiln liner body 3 and the top of the trolley 303 are in friction contact with each other until the ports of the kiln liner body 3 and the trolley 303 are flush with each other, thereby completing the pushing work of the trolley 303;

[0027] The rack transfer structure 9 includes a linear rack 902 fixed on the outer wall of one side of the inverted U-shaped protruding foot 301, and a driving gear 901 fixed on one end of the surface of the vertical shaft 8. The driving gear 901 and the linear rack 902 are meshed with each other. The rotation drive unit 10 includes a stepper motor 1001 installed on one side of the top end of the I-shaped cross arm 5, and a worm gear transmission structure 1002 installed at the output end of the stepper motor 1001 for driving the vertical shaft 8 to rotate. The vertical shaft 8 and the driving gear 901 are driven to rotate by the stepper motor 1001 and the worm gear transmission structure 1002. In this process, the self-locking function of the worm gear transmission structure 1002 can effectively realize the fixed-point parking function of the trolley 303, the linear rack 902 and other components, so that the trolley 303 will not slide or move after stopping.

[0028] The vertical shaft 8 drives the linear rack 902, the inverted U-shaped protrusion 301, the trolley 303 and other components to move through the active gear 901. Compared with manual operation, the driving structure is not affected by high temperature and can operate stably in harsh working environments, which helps to ensure the accuracy and safety of the operation.

[0029] When the embodiment of the present application is in use, the staff first opens the kiln door 2 so that the furnace mouth of the shuttle kiln shell 1 is in an open state, and then the staff manually pushes the trolley 303 for a distance. During this process, the bottom end of the kiln liner body 3 slides on the I-shaped track 7 through the sliding support structure. When the rack transfer structure 9 on the outer wall of one side of the trolley 303 is dynamically engaged with the vertical shaft 8 at the top of the I-shaped horizontal arm 5, the staff starts the rotary drive unit 10 to work, and the rotary drive unit 10 drives the vertical shaft 8 to rotate, so as to use the vertical shaft 8 to drive the rack transfer structure 9, the trolley 303 and other components to move in the extension direction of the I-shaped longitudinal arm 6 and the I-shaped track 7 until the trolley 303 is completely sent into the shuttle kiln shell 1. At this time, the kiln liner body 3 The bottom end of the trolley 303 is in frictional contact with the top end of the trolley 303 until the ports of the kiln inner tank body 3 and the trolley 303 are flush with each other, thereby completing the pushing of the trolley 303. When the workpiece on the top of the trolley 303 completes the calcination operation, the staff turns on the rotary drive unit 10 to work in reverse, so that the above-mentioned components can work in the opposite steps, thereby realizing the removal operation of the trolley 303 and the workpiece. The introduction of the electric drive mechanism can significantly improve the operating efficiency of the trolley 303 entering and moving out of the kiln, without the need for excessive physical effort by the operator, especially when dealing with large and heavy equipment, the rotary drive unit 10, the rack transfer structure 9 and other components can easily perform the task, greatly reducing the operating time and labor intensity, thereby improving the operating efficiency of the entire production line.
