DETAILED DESCRIPTION

[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. Based on the embodiments of 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] like Figure 1 and Figure 2 As shown, a preferred embodiment of the utility model proposes a novel vulcanization spray tank, which mainly includes a spray tank body 1 and a plurality of vulcanization nozzle assemblies 4 installed on the spray tank, wherein a plurality of connecting ports are arranged on the outer wall of the tapered portion at the lower end of the spray tank body 1, and a connecting pipe 2 is arranged at each connecting port, and the vulcanization nozzle assembly 4 is fixedly connected to the flange 3 at the front end of the connecting pipe 2 by bolts, so as to install and fix the vulcanization nozzle assembly 4, one end of the vulcanization nozzle assembly 4 extends into the interior of the spray tank through the connecting pipe 2, and the other end is externally connected to an air source assembly, and the air source assembly introduces high-pressure air into the vulcanization nozzle assembly 4, and then the vulcanization nozzle assembly 4 sprays the high-pressure air to all around the interior of the spray tank.

[0026] like Figure 2 As shown, the vulcanizing nozzle assembly 4 mainly includes three parts: a connecting head 41, a nozzle component and a dustproof mechanism 424. The connecting head 41 has a through hole that passes through the front and back. A flange 3 is provided at the front end of the connecting head 41 for fixed connection with the flange 3 on the connecting pipe 2, and the other end is detachably connected to the nozzle component. The dustproof mechanism 424 is located on the inner side of the nozzle component to prevent coal powder from entering the inside of the connecting head 41 from the nozzle component.

[0027] like Figure 3 , Figure 4 As shown, the above-mentioned nozzle component is composed of a mounting head 421 and a blowing net 422, wherein the blowing net 422 is cylindrical in shape and is formed by winding and enclosing a stainless steel screen. One end of the blowing net 422 is fixedly connected to the mounting head 421, and the other end is fixedly connected to a fixing plate 423. In this way, the air outlet area of ​​the blowing net 422 is increased, thereby improving the air outlet efficiency.

[0028] The mounting head 421 also has a through hole that passes through the front and back, and the dustproof mechanism 424 is installed inside the mounting head 421. At the same time, an external thread is provided on the outer circumference of the mounting head 421, and an internal thread that matches the external thread is provided on the inner circumference of the connecting head 41. The mounting head 421 is threadedly connected with the connecting head 41 for installation and removal. A polygonal screwing portion 4211 is formed on the outer circumference of the mounting head 421 so that the mounting head 421 can be screwed onto the connecting head 41. After passing through the connecting head 41 and the mounting head 421, the high-pressure air is blown out from the small holes on the blowing net 422.

[0029] like Figure 5 As shown, the dustproof mechanism 424 is composed of two baffles 4241 and two tension springs 4242. The baffle 4241 is semicircular in shape. In this example, one side of the baffle 4241 with an arc edge is hinged to the inner wall of the mounting head 421, and one end of the tension spring 4242 is hinged to the baffle 4241, and the other end is hinged to the inner wall of the mounting head 421. At the same time, a limited position portion is formed on the inner wall of the mounting head 421 to limit the rotation angle of the baffle 4241, so that the baffle 4241 It can only rotate between 0-90°. When the tension spring 4242 is in its original length, the two baffles 4241 are spliced ​​together to form a circle, blocking the channel in the mounting head 421. During operation, high-pressure air will impact the two baffles 4241, causing the two baffles 4241 to flip to both sides, allowing air to enter the injection net 422. When no air is entering, the two baffles 4241 return to their original positions under the action of the tension spring 4242 to block the channel, preventing coal powder from flowing back into the connecting head 41.

[0030] refer to Figure 6 The installation method of the baffle 4241 is not limited to the above-mentioned one. In other technical solutions, a rotating shaft 5 can be further arranged on the inner side of the mounting head 421. The sides where the straight edges of the two baffles 4241 are located are rotatably connected to the rotating shaft 5. When the high-pressure air impacts the baffle 4241, the two baffles 4241 flip upward, and the functions are the same.

[0031] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
