Steel containers have stress during casting and welding. In order to prevent LPG cylinders from deformation and cracking, they need to be heat treated, which requires an annealing furnace.

[0003] The Chinese patent with the announcement number CN211814578U discloses a steel cylinder heat treatment annealing furnace, which includes a heat treatment chamber, an annealing chamber and a conveying device, wherein the heat treatment chamber and the annealing chamber are both fan-shaped cavity structures; a driving motor and a driving shaft are arranged in the conveying device; a loading plate is arranged on the surface of the driving shaft; a conveying disk and a limit seat are arranged on the surface of the loading plate. The present invention uses a conveying device and a conveying disk to deliver the welded parts to be processed into the heat treatment chamber and the annealing chamber through the conveying device; at the same time, a rolling door is arranged to save space and energy; by arranging the annular structure of the conveying disk and the fan-shaped cavity structure of the two chambers, the heat treatment and annealing processes are mutually circulated, which improves the work efficiency and reduces the energy consumption; the setting of the rolling door further saves resources; and the setting of the limit seat fixes the steel cylinder to be processed, which increases the specificity of the annealing furnace.

[0004] With respect to the above-mentioned related technologies, in the prior art, the staff used a limit seat to limit the steel cylinder to ensure that the steel cylinder would not be displaced during movement. However, the size of the limit seat is fixed, resulting in that the limit seat in the prior art can only fix steel cylinders of one size and cannot fix steel cylinders of other sizes. Thus, the use scope of the annealing furnace is limited. Summary of the invention

[0005] In order to improve the application scope of the annealing furnace, the present application provides an annealing furnace for LPG cylinder production.

[0006] This application provides an annealing furnace for LPG cylinder production using the following technical solutions:

[0007] An annealing furnace for LPG cylinder production comprises a furnace body, a moving platform and a driving assembly for driving the moving platform to move are slidably fitted on the furnace body, a closed door and a starting member for driving the closed door to open and close are arranged at the entrance of the furnace body, a tool is arranged on the moving platform, the tool comprises a placement platform, a rotating disk, an arc rail and a clamping block, the placement platform is connected to the moving platform, a plurality of limiting grooves are opened on the placement platform, the rotating disk is rotatably connected to the bottom wall of the placement platform, a plurality of arc rails are connected to the rotating disk, the arc rails correspond to the limiting grooves one by one, the clamping block is slidably fitted in the limiting grooves and slidably fitted with the arc rails, a rotating assembly for driving the rotating disk to rotate is arranged on the placement platform, a filtering mechanism for filtering the gas inside the furnace body is also arranged on the furnace body, and a controller for controlling the operation of the furnace body is arranged on one side of the furnace body.

Then the driving assembly is controlled to control the moving table to enter the furnace body, and the starter is controlled to close the furnace body with the closed door. Finally, the filter mechanism is used to filter the gas generated during the heat treatment of the steel cylinder, thereby achieving the effect of heat treatment of the steel cylinder. The staff uses the cooperation of the rotating disk, the arc rail and the limiting groove to drive all the clamping blocks to move simultaneously to clamp the steel cylinder. This tooling can clamp steel cylinders of various sizes, thereby increasing the scope of use of the annealing furnace.

[0009] Optionally, several of the tooling are arranged on the mobile platform, and the rotating assembly includes a rotating ring gear and a rotating motor, wherein the rotating ring gear is connected to the side of each rotating disk, and two adjacent rotating ring gears are meshed with each other, and the rotating motor is connected to the bottom wall of the placement table and coaxially connected to one of the rotating disks, and the rotating motor is electrically connected to the controller.

[0010] By adopting the above technical solution, when driving the rotating disk to rotate, the staff starts the rotating motor through the controller to rotate one of the rotating disks, driving the rotating gear ring to rotate, thereby linking the other rotating disks, thereby achieving the effect of driving all the rotating disks to rotate at the same time.

[0013] Optionally, a plurality of balls are embedded on the bottom wall of the support ring, and the balls abut against the moving platform.

[0014] By adopting the above technical solution, the movement of the support ring in the limiting ring is sliding friction, which has a large friction force and increases the load of the rotating motor. The staff used balls to change the sliding friction of the support ring into rolling friction, reducing the friction of the support ring, making the support ring easier to rotate and extending the service life of the rotating motor.

When washing the gas, the staff uses the exhaust fan to transport the gas to the inside of the washing box. The gas appears in the washing liquid in the form of bubbles and moves along the baffle.

The crushing motor is connected to the washing box, the rotating rod is connected to the output shaft of the crushing motor, and several crushing rods are connected to the rotating rod and are located in the washing box.

[0018] By adopting the above technical solution, the gas appears in the form of bubbles in the washing liquid.

The remaining gas enters the exhaust pipe 5113, and the electric spark rod 524 is energized to ignite the wick 523. The carbon monoxide in the remaining gas reacts with the flame to generate new carbon dioxide and discharge it out of the exhaust pipe 5113.
