DETAILED DESCRIPTION

[0023] 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.

[0024] See also Figure 1-8 The utility model provides a technical solution for a dry powder fire extinguisher shell paint spraying and drying equipment: a dry powder fire extinguisher shell paint spraying and drying equipment, comprising: a slide 1, the outer wall of the slide 1 is installed with a plurality of mounting rods 16, and the slide 1 can be installed at a designated position of a workshop by using the mounting rods 16 and bolts, etc., and a "cross" shaped blind groove is opened at the bottom end of the outer wall of the slide 1, and a chain 2 is slidably embedded in the inner cavity of the slide 1, and the chain 2 is prevented from falling out of the inner cavity of the slide 1 by using the position limiting of the blind groove, and the inner wall of the slide 1 is respectively installed with shells 13 on the left and right sides. A sprocket 14 is rotatably installed in the inner cavity of the shell 13, and the sprocket 14 is meshed with the chain 2. A motor 15 is installed on the top of one of the shells 13, and the output end of the motor 15 is fixedly connected to the sprocket 14 through a coupling. Turning on the motor 15 can drive the sprocket 14 connected thereto to rotate, thereby driving the chain 2 to rotate. Using the transmission of the chain 2, the other sprocket 14 will rotate synchronously, while ensuring the overall stable operation of the chain 2. A fire extinguisher tank 5 is hung on the bottom end of the chain 2, and the fire extinguisher tank 5 can be directionally transported as the chain 2 rotates.

[0025] Among them, a connecting piece 201 is installed at the bottom end of the chain 2, and one end of the steel cable 3 is installed on the outer wall of the connecting piece 201, and a limiting hook 4 is installed on the other end of the steel cable 3, and the outer wall of the limiting hook 4 is supported in the inner cavity of the fire extinguisher tank body 5. The limiting hook 4 is made of elastic metal, plastic, rubber and other materials, and the bottom end width of the limiting hook 4 is twice the middle width. The free end of the limiting hook 4 is pressed close to the end connected to the steel cable 3, so that the bottom end of the limiting hook 4 is compressed and deformed to narrow the width, and then it can be inserted into the inner cavity of the fire extinguisher tank body 5. When the external force is removed, the elastic force of the limiting hook 4 is used to restore itself. The bottom end width of the limiting hook 4 is greater than the width of the port of the fire extinguisher tank body 5, so that the fire extinguisher tank body 5 can be limited and hung. The same operation can also make the fire extinguisher tank body 5 detach from the outer wall of the limiting hook 4.

[0026] As a preferred embodiment, further, a spray chamber 6 and a drying chamber 8 are respectively installed on the front and rear sides of the bottom end of the slide 1. The spray chamber 6 and the drying chamber 8 are both boxes with an opening at the top. The inner cavity of the spray chamber 6 is equipped with a plurality of nozzles 7, which are connected to an external paint bucket. The paint is evenly sprayed through the nozzles 7. A plurality of heating wires 9 are respectively installed on the front and rear sides of the inner wall of the drying chamber 8. The heating wires 9 can generate heat when the external power supply is turned on, so that the objects passing through the inner cavity of the drying chamber 8 can be dried. The fire extinguisher tank body 5 can move in the inner cavities of the spray chamber 6 and the drying chamber 8. When the fire extinguisher tank body 5 moves to the inner cavity of the spray chamber 6 with the operation of the chain 2, the nozzle 7 is used for uniform spraying. Then the fire extinguisher tank body 5 leaves the inner cavity of the spray chamber 6 and enters the inner cavity of the drying chamber 8, and is quickly dried by the high temperature of the heating wires 9.

[0027] Among them, several nozzles 7 are equidistantly installed on the front and rear sides and the upper and lower ends of the inner wall of the spray chamber 6, and the free ends of the nozzles 7 face the center direction of the spray chamber 6 to ensure uniform spraying and full coverage of the outer wall of the fire extinguisher tank 5.

[0028] As a preferred embodiment, further, fans 10 are respectively installed on the front and rear sides of the outer wall of the drying chamber 8, the suction end of the fan 10 is connected with the bottom end of the inner cavity of the drying chamber 8, and the output end of the fan 10 extends into the top end of the inner cavity of the drying chamber 8 through a pipe 11, and an air outlet 12 is installed at one end of the pipe 11 extending into the inner cavity of the drying chamber 8, and the air outlet 12 is set downward. When the fan 10 is turned on, the air at the bottom end of the inner cavity of the drying chamber 8 is sucked out, and the air passes through the pipe 11 and finally returns to the top end of the inner cavity of the drying chamber 8 through the air outlet 12, thereby accelerating the air flow in the inner cavity of the drying chamber 8 and accelerating the drying. At the same time, the air outlet at the end of the air outlet 12 is directly blown downward to avoid excessive hot air escaping upward.
