DETAILED DESCRIPTION

[0034] The preferred specific implementation methods for implementing the present utility model are described in detail below, and a clear and complete description is made in conjunction with the accompanying drawings.

[0035] See also Figure 1-Figure 8 The utility model provides a reciprocating gyratory grading vibrating screen.

[0036] The screening box 001 includes a box body 100, and a stirring box 110 for breaking up the block nickel-based alloy powder is installed on the upper end of the box body 100. A feeding hopper 111 is fixedly installed on the upper end of the stirring box 110 for feeding the nickel-based alloy powder into the stirring box 110. A stirring rod 112 for breaking up the block nickel-based alloy powder is installed inside the stirring box 110. A roller 113 for controlling the rotation of the stirring rod 112 is fixedly installed at one end of the stirring rod 112. The motor for controlling the rotation of the roller 113 drives the stirring rod 112 to rotate, thereby breaking up the block nickel-based alloy powder thrown into the roller 113, so that it can be fully used to avoid waste.

[0037] A vibrating screen 120 for preliminary screening of nickel-based alloy powder is installed at the upper end of the inner cavity of the box 100. The vibrating screen 120 is tilted, and the horizontal height of the end close to the feed pipe 141 is lower than the end close to the electric push rod 121. The electric push rod 121 for controlling the vibration of the vibrating screen 120 is movably installed at the lower right end of the vibrating screen 120. The electric push rod 121 is started to drive the right side of the vibrating screen 120 to move up and down, and the left side of the vibrating screen 120 is movably installed at one end of the feed pipe 141. A partition 130 for separating the inner cavity of the box 100 is fixedly installed in the middle of the box 100. A discharge port 131 is opened in the middle of the partition 130. The large-particle nickel-based alloy powder is transported to the inside of the auger conveyor 140 through the vibrating screen 120 for preliminary screening, and the remaining nickel-based alloy powder falls to the upper end of the screening frame 200 through the discharge port 131.

[0038] An auger conveyor 140 for conveying large-particle nickel-based alloy powder to the upper end of the stirring box 110 is installed at the upper left end of the partition 130, a feed pipe 141 is fixedly installed at the lower end of the auger conveyor 140, and a discharge pipe 142 is fixedly installed at the upper end of the auger conveyor 140, so that the large-particle nickel-based alloy powder is transported to the stirring rod 112 again for dispersion.

[0039] A supporting base 150 for supporting the screening device 002 is installed at the lower end of the screening box 001, a limiting groove 151 is provided at the upper end of the supporting base 150, a power component 160 for controlling the vibration of the screening device 002 is installed at the upper end of the supporting base 150, the power component 160 includes a cam 161, a rotating shaft 162 is fixedly installed at the lower end of the cam 161, and a motor 163 for cooperating with the rotating shaft 162 to control the rotation of the cam 161 is installed at the lower end of the rotating shaft 162.

[0040] The motor 163 is started, so that the rotating shaft 162 drives the cam 161 to rotate, and the cam 161 and the guide protrusion 261 collide with each other, thereby driving the screening frame 200 to vibrate back and forth. A collecting box 170 for collecting the screened nickel-based alloy powder is installed at the lower end of the box body 100. Two collecting boxes 170 are provided, one is located under the unloading plate 244, and the other is located under the unloading plate 1 235, so as to facilitate the collection of two different sizes of nickel-based alloy powders.

[0041] A screening device 002 for screening nickel-based alloy powder is installed inside the screening box 001. The screening device 002 includes a screening frame 200. The upper end of the screening frame 200 is a conical surface, which facilitates the nickel-based alloy powder that falls from the discharge port 131 to the upper end of the screening frame 200 to move to the side of the screening frame 200.

[0042] A baffle 210 for blocking the nickel-based alloy powder is fixedly installed on the upper end of the screening frame 200, and a discharge port 211 is opened on the right side of the baffle 210. A lever 220 for pushing the nickel-based alloy powder to the discharge port 211 is installed on the upper end of the screening frame 200, and a rotating shaft 221 is fixedly installed on one end of the lever 220. A motor 222 for cooperating with the rotating shaft 221 to control the rotation of the lever 220 is installed on the lower end of the rotating shaft 221. When the motor 222 is started, the rotating shaft 221 drives the lever 220 to rotate, pushing the nickel-based alloy powder on the upper end of the screening frame 200 to the discharge port 211, and falling to the upper end of the bottom plate 1 231 through the discharge port 211.

[0043] The outer wall of the screening frame 200 is installed with a filter assembly 230 for secondary screening of the nickel-based alloy powder. The filter assembly 230 includes a bottom plate 231. A plurality of discharge holes 232 are provided in the middle of the bottom plate 231 to facilitate the small-particle nickel-based alloy powder to fall toward the guide assembly 240. Side plates 1 233 and 234 for blocking the nickel-based alloy powder are fixedly installed on the sides of the bottom plate 231. A discharge plate 235 is installed at one end of the filter assembly 230 to facilitate the nickel-based alloy powder to fall into the interior of the collection box 170. The screening efficiency is increased by the arrangement of the filter assembly 230.

[0044] A guide assembly 240 for guiding the nickel-based alloy powder is fixedly installed on the outer wall of the screening frame 200, and the guide assembly 240 is located below the filtering assembly 230. The guide assembly 240 includes a bottom plate 241, and the sides of the bottom plate 241 are fixedly installed with side plates 3 242 and 4 243 for blocking the nickel-based alloy powder. A discharge plate 244 is fixedly installed at one end of the guide assembly 240 to facilitate the nickel-based alloy powder to fall into the interior of the collection box 170.

[0045] The bottom of the screening frame 200 is fixedly installed with a slider 250 for moving forward and backward in the groove cavity of the limiting groove 151. The bottom of the screening frame 200 is provided with a limiting groove 260. The cam 161 rotates in the groove cavity of the limiting groove 260. The side walls at the front and rear ends of the limiting groove 260 are fixedly installed with guide protrusions 261 for cooperating with the cam 161 to control the screening frame 200 to move forward and backward. The motor 163 is started to drive the rotating shaft 162 to rotate, so that the cam 161 rotates. When the filter 1 rotates, it contacts the guide protrusion 261, thereby driving the screening frame 200 to move forward and backward, generating vibrations that synchronously drive the filter assembly 230 to vibrate, so that the small particles of nickel-based alloy powder above the bottom plate 1 231 fall to the top of the bottom plate 241 through the discharge hole 232. The vibration of the screening frame 200 facilitates the filter assembly 230 and the guide assembly 240 to drive the nickel-based alloy powder to fall into the two collection boxes 170 through the discharge plate 1 235 and the discharge plate 244 respectively.
