[0027] Example 1

[0028] like Figure 1 and Figure 7 As shown, a device for discharging and screening powder in this embodiment, the utility model comprises: a single-port discharger 3, a powder screening device 4, a material transport receiving tube 2 and a discharging straight-through pipe 1, the single-port discharger 3 is sleeved on the outer side of the material transport receiving tube 2, a powder screening device 4 is slidably arranged between the material transport receiving tube 2 and the single-port discharger 3, a discharging straight-through pipe 1 for discharging is installed at the bottom of the single-port discharger 3, the discharging port of the discharging straight-through pipe 1 is connected to the single-port discharger 3, a second discharging port 21 is opened on the material transport receiving tube 2, and the second discharging port 21 corresponds to the discharging port of the single-port discharger 3.

[0029] Specifically, Figure 1 , 2 and Figure 8As shown, the powder screening device 4 is formed by bending and welding 1.0 mm thick iron sheet, the bending area of ​​the powder screening device 4 is provided with an array of screening holes 42 with an opening diameter of 3.0 mm, and a first discharge port 41 is also provided on the bending area of ​​the powder screening device 4, and limit baffles 43 are welded on both sides of the powder screening device 4, the limit baffles 43 are used for quickly pushing and pulling the powder screening device 4 and limiting the powder screening device 4, the overall sharp edges of the powder screening device 4 are blunted and burred to ensure that the powder screening device 4 reduces friction in the material transport pipe 2 and pushes and pulls smoothly, the spacing of the screening holes 42 is 6 mm, with a total of 8 rows and 10 columns, the hole mouths are polished smooth to ensure uniform and smooth material discharge, the aperture of the screening hole 42 can be designed with different sizes according to different usage scenarios, and the size of the first discharge port 41 is 60*35 mm.

[0030] Specifically, Figure 3 As shown, the single-port discharger 3 includes a first pipe fitting 31 and a second pipe fitting 32. The second pipe fitting 32 is installed on the side wall of the first pipe fitting 31. The cavities of the first pipe fitting 31 and the second pipe fitting 32 are connected. The first pipe fitting 31 and the second pipe fitting 32 are connected to form a "T" shape, and the second discharge port 21 corresponds to the top of the second pipe fitting 32.

[0031] Specifically, Figure 7 and 8 As shown, the rotary material blocking baffle 5 is rotatably installed on the outer wall of the material transport receiving tube 2 and is located in the inner cavity of the first pipe 31. The rotary material blocking baffle 5 can rotate along the circumferential direction of the material transport receiving tube 2. When the rotary material blocking baffle 5 rotates along the circumferential direction of the material transport receiving tube 2 until it coincides with the second discharge port 21, the second discharge port 21 is closed to stop unloading or feeding. Conversely, when the rotary material blocking baffle 5 rotates to not coincide with the second discharge port 21, the second discharge port 21 is opened and the powder screening device is in a feeding or unloading state. The feed enters the inner cavity of the second pipe 32 through the second discharge port 21 for unloading.

[0032] like Figure 5 , 7 and Figure 8 As shown, the powder screening device 4 can translate between the material transport receiving tube 2 and the single-port discharger 3; when the powder screening device 4 moves along the axial direction of the material transport receiving tube 2, the first discharge port 41 on the powder screening device 4 coincides with the second discharge port 21 on the material transport receiving tube 2, the unloading and powder screening device is in a fast unloading device; and when the powder screening device 4 moves along the axial direction of the material transport receiving tube 2, the screening hole 42 on the powder screening device 4 coincides with the second discharge port 21 on the material transport receiving tube 2, the unloading and powder screening device can screen the coarseness of the feed.

[0033] Specifically, the shell material of the single-port discharger 3 is 304 stainless steel. The single-port discharger 3 adopts an opening and closing design, which facilitates the installation of the rotary material blocking plate 5, the powder screening device 4 and the material transport receiving tube 2 inside the cavity of the single-port discharger 3, and is locked and fixed with four-corner mounting screws.

[0034] Specifically, Figure 4-8 As shown, the rotary material blocking baffle 5 adopts an arc-shaped design with a wall thickness of 3mm, a length of 93mm, and an outer diameter of 35.5mm. It can wrap the first discharge port 21 of the entire material transport receiving tube 2, and can rotate smoothly inside the cavity of the first pipe 31. A fixing ear is designed on one side edge of the rotary material blocking baffle 5 for easy fixed installation.

[0035] Specifically, Figure 8 The material transport receiving tube 2 shown is installed through the first pipe 31. The material transport receiving tube 2 is designed with a second discharge port 21 with a size of 70*35mm and is installed downward. The entire material transport receiving tube 2 is made of PVC and is placed horizontally for transporting feed.

[0036] Specifically, Figure 6 As shown, the material discharge straight-through pipe 1 is designed as a hose with a diameter of 59 mm. The length of the material discharge straight-through pipe 1 is determined according to the production design situation. The feeding end of the material discharge straight-through pipe 1 is installed at the port of the second pipe fitting 32.

[0037] Preferably, a full-feed sensor is provided on the material discharge straight-through pipe 1, and the full-feed sensor is used to monitor whether the material transport receiving pipe 2 is full of feed, and is used to monitor the discharge situation and issue an alarm reminder. When the feed is full, the sensor will transmit the information to the electronic control system, and the electronic control system will automatically cut off the power supply, the main machine will stop running, and the entire discharge process is completed.

[0038] The working principle of the utility model is as follows: the feed enters the inner cavity of the material transport receiving tube 2 under the pushing action of the plug chain assembly, and when the rotary material blocking baffle 5 rotates to the upper cavity inside the first pipe 31, the utility model is in a discharging state. At this time, the device will decide whether to discharge the material quickly or need powdered fine materials according to the working condition switch. When the first discharge port 41 on the powder screening device 4 moves to coincide with the second discharge port 21 on the material transport receiving tube, the utility model is in a fast discharge mode. When the screening hole 42 on the powder screening device 4 moves to coincide with the second discharge port 21 on the material transport receiving tube, the device can screen the fine materials, and then the powdered materials enter the discharge straight-through pipe 1 for discharge. When the feed storage device at the lower end is filled with the feed, the full material sensor will promptly alarm and remind. At this time, the rotary material blocking baffle 5 can be rotated to the lower cavity inside the single-port discharger 3 to coincide with the second discharge port 21, so as to quickly close the second discharge port 21 and achieve the purpose of stopping the discharge.
