[0003] The existing drying room can rotate the nozzle to achieve the effect of uniform drying. For example, Chinese patent application No. CN202020548898.7 discloses an environmentally friendly, energy-saving, intelligent hot air circulation drying room, including a drying room and a support plate.

[0004] This drying room sprays hot air from top to bottom through nozzles. Since there are usually multiple layers of castings placed on the shelves, the castings on the upper side will block the wind sprayed from the nozzles, which is not conducive to the hot air blowing evenly to the castings.

[0024] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0025] See also Figure 1-5 The utility model provides a technical solution: a hot air circulation drying room for casting production, including a drying room 1, both sides of the interior of the drying room 1 are symmetrically connected with limit plates 2, a hollow shell 3 is provided between the two corresponding limit plates 2, both sides of the shell 3 are connected with sliders 4, and the limit plates 2 are provided with a slide groove 5 adapted to the slider 4 on the side close to the slider 4, a Y-shaped tube 6 is longitudinally provided on the upper surface of the drying room 1, the lower end of the Y-shaped tube 6 passes through the drying room 1 and is symmetrically connected with two telescopic tubes 7, the two telescopic tubes 7 are respectively connected with the corresponding shells 3, a fan 8 is installed on the upper surface of the drying room 1, and the air outlet of the fan 8 It is connected to the upper end of the Y-tube 6, and the air inlet of the fan 8 is connected to a pipe 9, one end of the pipe 9 is connected to the drying room 1, and push rods 10 are longitudinally installed on both sides of the drying room 1. The upper and lower ends of the push rods 10 are rotatably connected to the shell body 3 and the drying room 1 respectively. A plurality of holes 11 are symmetrically penetrated through the lower surface of the shell body 3. A heating pipe 12 is provided inside the Y-tube 6. The push rod 10 is a hydraulic cylinder. The part of the limit plate 2 close to the corner of the drying room 1 is arc-shaped, and the hole 11 is inclined away from the shell body 3. A dehumidification pipe is provided on the surface of the drying room 1, which is mainly used to discharge water vapor. It is a prior art and will not be repeated here.

[0026] During operation, the fan 8 blows air into the Y-shaped tube 6, and the heating tube 12 heats the air in the Y-shaped tube 6. The hot air enters the shell 3 through the telescopic tube 7, and then the hot air is blown to the casting on the upper side from the hole 11. The push rod 10 contracts, thereby pulling the shell 3, driving the slider 4 to slide in the slide groove 5, so that the shell 3 moves along the trajectory of the slide groove 5. When the shell 3 moves to the side inside the drying room 1, the hole 11 will be aimed at the side of the casting for blowing. As the push rod 10 continues to contract, the shell 3 is driven to move downward. During the movement, the air blown out of the hole 11 will contact the castings of each layer in turn. Since the hole 11 is inclined, even if the shell 3 is not moved to the bottom of the drying room 1, the air blown out of the hole 11 can also blow to the casting on the lower side. The push rod 10 is repeatedly extended and retracted to make the hot air repeatedly blow to the castings of each layer. The hot air after being blown out will be sucked into the fan 8 by the pipeline 9, and then enter the Y-shaped tube 6 again, thereby realizing hot air circulation.

[0027] See also Figure 1-5The utility model provides a technical solution: both sides of the shell 3 are connected with fixing plates 13, the outer surface of the fixing plates 13 is penetrated with screw holes 14, the inner wall of the drying room 1 is opened with openings corresponding to the positions of the screw holes 14, and the inner wall of the opening is provided with threads.

[0028] During operation, by setting the fixing plate 13, the screw hole 14 and the opening, the fixing plate 13 can be fixed by screwing the fasteners into the screw hole 14 and the opening, so that the housing 3 can be installed more conveniently.

[0029] See also Figure 1-5 The utility model provides a technical solution: the outer surface of the Y-shaped tube 6 is covered with rubber.

[0030] During operation, the sealing performance between the Y-shaped tube 6 and the drying chamber 1 can be improved by setting the rubber.

[0031] See also Figure 1-5 The utility model provides a technical solution: the outer surface of the pipeline 9 is covered with a rock wool tube 15.

[0032] During operation, the rock wool tube 15 can provide heat preservation to the hot air in the pipeline 9 and reduce the heat loss of the hot air when passing through the pipeline 9 .

[0033] See also Figure 1-5 The utility model provides a technical solution: the slider 4 is made of stainless steel.

[0034] During operation, the slider 4 made of stainless steel has better strength and wear resistance, which is conducive to the long-term use of the slider 4.

[0035] See also Figure 1-5 The utility model provides a technical solution: both sides of the shell 3 are connected to the limiting blocks 16, the limiting blocks 16 are in contact with the outer surface of the limiting plate 2, and the limiting blocks 16 are made of metal.

[0036] During operation, when the shell 3 moves, the limit block 16 will move along the outer surface of the limit plate 2, and the limit block 16 can play a limiting role, making the movement process of the shell 3 more stable.

[0037] See also Figure 1-5 The utility model provides a technical solution: the heating tube 12 is a spiral electric heating tube.

[0038] When working, the spiral electric heating tube has a better heating effect, and at the same time, the spiral electric heating tube can leave sufficient space for the flow of heating air in the Y-shaped tube 6.

[0039] In summary, the fan 8 blows air into the Y-shaped tube 6, and the heating tube 12 heats the air in the Y-shaped tube 6. The hot air enters the shell 3 through the telescopic tube 7, and then the hot air blows toward the upper casting from the hole 11. The push rod 10 contracts, thereby pulling the shell 3, driving the slider 4 to slide in the slide groove 5, and moving the shell 3 along the track of the slide groove 5. When the shell 3 moves to the side of the inside of the drying room 1, the hole 11 will blow air toward the side of the casting. As the push rod 10 continues to contract, it drives the shell 3 to move downward, and the shell 3 moves. During the process, the wind blown out of the hole 11 will contact the castings of each layer in turn. Since the hole 11 is set obliquely, even if the shell 3 is not moved to the bottom of the drying room 1, the wind blown out of the hole 11 can blow to the castings on the lower side. The push rod 10 can repeatedly extend and retract to make the hot wind repeatedly blow to the castings of each layer. The blown hot air will be sucked into the fan 8 by the pipeline 9, and then enter the Y-shaped tube 6 again, so as to realize the hot air circulation. The fixing plate 13 can be fixed by screwing the fasteners into the screw holes 14 and the openings, and the shell 3 is relatively convenient to install.
