[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0017] Depend on Figs. 1 to 4 It is known that a coarse and fine screening device for thermal insulation covering agent metallurgical auxiliary materials includes a tank-shaped body 1, with multiple support legs 7 at the bottom of the body 1, a feed inlet 8 at the top of the body 1, a first screen 2 and a second screen 3 inside the body 1, and two rotating rings 9 inside the body 1. The first screen 2 and the second screen 3 are rotatably connected inside the rotating rings 9. A first guide pipe 4 located at the bottom of the first screen 2 and a second guide pipe 5 located at the bottom of the second screen 3 are provided on the body 1. The first guide pipe 4 and the second guide pipe 5 extend outside the body 1. The first screen 2 and the second screen 3 can rotate inside the body 1. The mesh diameter of the second screen 3 is smaller than the mesh diameter of the first screen 2. A discharge port 6 is opened at the bottom of the body 1.
[0018] In practical use, this utility model
[0019] The thermal insulation covering agent powder is fed into the main body 1 through the feed inlet 8. The equipment is started, and the first screen 2 and the second screen 3 rotate. The rotation of the first screen 2 causes the thermal insulation covering agent to undergo centrifugal motion. The thermal insulation covering agent particles smaller than the aperture of the first screen 2 fall onto the second screen 3 for further screening. The thermal insulation covering agent particles larger than the aperture of the first screen 2 remain on the first screen 2. The first feed pipe 4 is opened periodically to discharge the thermal insulation covering agent particles larger than the aperture of the first screen 2 to the outside. Similarly, the second screen 3 screens the thermal insulation covering agent. The thermal insulation covering agent particles larger than the aperture of the second screen 3 but smaller than the aperture of the first screen 2 are discharged from the second feed pipe 5, and the thermal insulation covering agent particles smaller than the aperture of the second screen 3 are discharged from the outlet 6. One screening can separate the thermal insulation covering agent into three grades, which greatly improves the screening efficiency.
[0020] In this device, the number of screens and the size of the mesh can be set according to actual needs, so as to screen the thermal insulation covering agent more finely.
[0021] The motor 10 is arranged at the top of the body 1, and the motor 10 is connected with the first screen 2 through a connecting rod 11; the body 1 is internally provided with a transmission shaft 12, and the transmission shaft 12 is respectively connected with the bottom of the first screen 2 and the second screen 3 at two ends, thereby forming a structure for synchronous rotation of the first screen 2 and the second screen 3.
[0022] The first screen 2 and the second screen 3 cannot be directly connected in transmission due to the first material guide pipe 4 and the second material guide pipe 5 in the body 1, therefore, the transmission shaft 12 is arranged to realize the transmission of the first screen 2 and the second screen 3, so that the motor 10 can drive multiple screens to rotate synchronously, thereby realizing the screening of the thermal covering agent.
[0023] The first screen 2 and the second screen 3 are internally provided with protrusions 13 between mesh holes; under the action of centrifugal force, the thermal covering agent will produce circumferential motion, and the existence of the protrusions 13 enables the thermal covering agent particles larger than the hole diameter to be lifted and away from the screen, thereby improving the filtering efficiency of the screen.
[0024] Compared with the prior art, the utility model has the following beneficial effects: the multiple screens are arranged in the body, the thermal covering agent particles are screened step by step, the thermal covering agent is divided into multiple grades at one time, the screening time is greatly shortened, and the screening efficiency is improved.
