Abstract
Description
Technical Field
[0001] The utility model relates to the field of isostatic graphite processing equipment, in particular to a device for screening isostatic graphite powder. Background Art
[0002] During the production of isostatic graphite, powder preforming is required. To ensure the quality of the preforming, the raw materials must be ground first, and then the powder must be screened to remove larger particles. Only powder with uniform particle size can be obtained for preforming.
[0003] Powder screening usually uses a sieve plate, which uses the diameter of the sieve holes on the sieve plate to screen the powder. Powder with a particle size larger than the sieve hole diameter is retained on the sieve plate, while powder with a particle size smaller than the sieve hole diameter passes through the screening smoothly and enters the receiving hopper below. During the screening process, the particles retained on the sieve plate cover part of the sieve holes, affecting the screening efficiency of the powder and need to be cleaned. The simplest way is to flip the sieve plate and pour out the particles retained on the sieve plate. However, in order to avoid dust during the screening process, the upper lower hopper is often close to the sieve plate, which affects the flipping of the sieve plate and needs to be improved.

[0015] Figure 1 It is a structural diagram of the utility model;
[0016] Figure 2 yes Figure 1 Schematic diagram of the structure after the screen plate installation frame is flipped up. DETAILED DESCRIPTION
[0017] The following combination Figures 1 to 2 The technical solution of the present utility model is further illustrated by specific embodiments.
[0018] like Figure 1 As shown, the device for screening isostatic graphite powder includes: a gantry 1, a lower hopper 5, a sieve plate 3, a sieve plate mounting frame 2 and a receiving hopper 4. The receiving hopper 4 is fixed in the gantry 1, and the screened isostatic graphite powder flows into the receiving hopper 4 for temporary storage.
[0019] A hanger 10 is provided in the gantry 1 and is located on the left side of the receiving hopper 4. The screen plate mounting frame 2 is flippably arranged above the receiving hopper 4. An ear seat 23 extending into the hanger 10 is provided on the left side of the screen plate mounting frame 2. A rotating shaft 10 is provided in the hanger 10 and horizontally passes through the ear seat 23 to support the flipping of the screen plate mounting frame 2 with the rotating shaft 1 as the center.
[0020] A hoist 6 is provided on the gantry 1 above the left side of the hanger 10, a handle 18 is provided on the end of the screen plate mounting frame 2 away from the hanger 10, and a guide wheel 21 is provided on the gantry 1 above the screen plate mounting frame 2. A steel wire rope 7 is provided in the hoist 6, and one end of the steel wire rope 7 passes through the guide wheel 21 and is connected to the handle 18. Figure 2 As shown, the right end of the screen plate mounting frame 2 is turned upward by winding the wire rope 7 by the winch 6.
[0021] A guide trough 8 is provided in the gantry 1, extending obliquely downward from the bottom of the rotating shaft 9 to the left side of the gantry 1. The sieve plate 3 is obliquely placed in the sieve plate mounting frame 2, and the left end is obliquely upward pointing to the hanger 10. Figure 2 As shown, the right end of the sieve plate mounting frame 2 is flipped upward, and the sieve plate 3 is flipped accordingly, so that the particles retained on the sieve plate 3 roll along the inclination of the sieve plate 3 and fall into the guide trough 8, and finally enter the waste box 24 below the end of the guide trough 8 for centralized processing, which can be subjected to secondary grinding to reduce costs.
[0022] The lower hopper 5 is arranged on the gantry 1 so as to be movably disposed above the screen plate mounting frame 2. Figure 2 As shown, a first material valve 20 is provided at the bottom of the lower hopper 5, and a flexible material guide pipe 19 is provided at the bottom of the first material valve 20, which extends to the top of the screen plate mounting frame 2, to avoid dust problems and reduce damage to the flexible material guide pipe 19 caused by misoperation of the screen plate mounting frame 2 and flipping and hitting the flexible material guide pipe 19.
[0023] The lower hopper 5 is used to temporarily store isostatically pressed graphite powder to be screened. After opening the first valve 20, the isostatically pressed graphite powder to be screened enters the sieve plate mounting frame 2 through the flexible material guide tube 19, rolls along the sieve plate 3 for screening, and qualified powder falls into the receiving hopper 4 below. The bottom of the receiving hopper 4 is provided with a second valve 25. Opening the second valve 25 can release qualified powder, making operation simple.
[0024] In order to prevent the flexible material guide tube 19 from affecting the flipping of the screen plate mounting frame 2, a slide rail 13 is horizontally arranged on both sides of the lower hopper 5 on the top of the gantry 1, and a slide seat 12 is arranged on the slide rail 13. Fixed plates 11 connected to the slide seat 12 are arranged on both sides of the lower hopper 5, which can improve the stability of the lateral movement of the lower hopper 5.
[0025] A chain 15 is horizontally arranged on the gantry 1, and a connecting rod 14 connected to the fixed plate 11 is arranged on the chain 15. Figure 2 As shown, the movement of the chain 15 drives the fixed plate 11 and the lower hopper 5 to move horizontally. In this embodiment, the gantry 1 is provided with a sprocket 16 supporting the chain 15 and a motor 17 driving the sprocket 16 to rotate, which is easy to operate.
[0026] The receiving hopper 4 is provided with a rubber block 22 located below the right end of the sieve plate mounting frame 2. After the sieve plate mounting frame 2 is tilted down and reset, the rubber block 22 provides elastic support for the right end of the sieve plate mounting frame 2, resulting in a good shock absorption effect. When a large amount of particulate matter remains on the sieve plate 3, the first material valve 20 is closed, and the sprocket 16 is driven clockwise by the motor, causing the lower hopper 5 and the flexible material guide tube 19 to move rightward to avoid the sieve plate mounting frame 2. The sieve plate mounting frame 2 is tilted up for automatic cleaning, and the larger particles on the sieve plate 3 roll along the inclination of the sieve plate 3 and fall into the material guide trough 8, which facilitates the rapid cleaning and reset of the sieve plate, thereby improving production efficiency.

For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
