[0022] Example 1

[0023] like Figure 1 As shown,

[0024] A powder rapid coarse screening sampling device comprises a frame 1, a screen 2 and a vibration motor 3, wherein the frame 1 is used to support the entire device, the bottom of the screen 2 is fixed to the frame 1 through a shock-absorbing spring 4, the screen 2 is tilted on the frame 1, and the tilt angle of the screen 2 on the frame 1 can be adjusted. According to the fluidity of different raw materials, the tilt angle of the screen 2 on the frame 1 can be adjusted to achieve rapid flow and discharge of the powder, while ensuring rapid separation of foreign matter and lumps.

[0025] In order to adjust the inclination angle of the screen 2, an adjusting bolt 5 is provided between the shock-absorbing spring 4 at the front end of the screen 2 and the frame 1. The adjusting bolt 5 is threadedly connected to the frame 1. A pad is provided on the top of the adjusting bolt 5, and the bottom of the shock-absorbing spring 4 is fixed on the pad. The height of the shock-absorbing spring 4 can be adjusted by adjusting the bolt 5, thereby adjusting the height of the front end of the screen 2, thereby realizing the adjustment of the inclination angle of the screen 2, which is convenient for debugging the inclination angle according to the fluidity of the raw materials.

[0026] In this embodiment, the elasticity of the shock-absorbing spring 4 is required to ensure that the screen 2 vibrates quickly with high frequency and low amplitude. If the vibration amplitude is too large, the powder material may easily jump, and the powder material may jump over the block 7 and directly enter the waste bag.

[0027] In this embodiment, the screen 2 uses a 10-mesh screen 2. The 10-mesh screen 2 is used to filter foreign matter or lumps. A collection hopper 6 is provided at the bottom of the screen 2. The collection hopper 6 is connected to the bottom of the screen 2 by a canvas to form a soft connection. The collection hopper 6 is fixed on the frame 1. The powder filtered by the screen 2 can enter the collection hopper 6 and then be discharged from the discharge port 11 at the bottom of the collection hopper 6. In this embodiment, two vibration motors are provided on the screen 2, and the two vibration motors 3 provide vibration power to the screen 2.

[0028] The upper surface of the screen 2 is fixed with evenly spaced blocks 7, which are perpendicular to the flow direction of the material on the screen 2. The blocks 7 can prevent the powder from being directly discharged without being filtered by the screen 2. The blocks 7 can be arranged at different heights according to the characteristics of different raw materials, which can not only block the powder to a certain extent, prevent the powder from falling through the screen 2 and directly sliding down from the upper part of the screen 2 to cause waste, but also ensure the rapid flow of foreign matter and agglomerates, so as to achieve the separation of powder and foreign matter agglomerates.

[0029] In this embodiment, there are 4 barriers 7 evenly distributed on the screen 2, which fully realizes the rapid separation of powder and foreign matter agglomerates.

[0030] In this embodiment, a shell 8 is provided on the top of the frame 1 . The shell 8 is arranged above and on four sides of the screen 2 . A feed inlet 9 is provided above the shell 8 , and a waste outlet 10 is provided at the bottom of the shell 8 .

[0031] In this embodiment, the feed port 9 of the outer shell 8 is connected to the ton bag, and the discharge port 11 of the collecting hopper 6 is connected to the waste bag. The feed port 9 and the ton bag as well as the discharge port 11 and the waste bag are fixed by round steel rings to prevent dust from scattering during the sampling process.

[0032] The utility model discloses a device for rapid coarse screening of powder, which is used for rapid coarse screening and random inspection of whole packages of mineral raw material powder. The screen 2 is designed to be inclined. The inclined screen 2 uses gravity and vibration to realize the automatic flow of powder. After the powder flows to the end, all the powder passes through the screen 2 into the ton bag, and the abnormally agglomerated raw materials enter the waste bag. A block 7 is installed on the screen 2 to prevent the powder from flowing quickly into the foreign body bin; the inclination of the screen 2 is adjusted by the automatic adjustment bolt 5, and the inclination angle can be adjusted conveniently, which is convenient for on-site debugging. This device is more convenient and faster, and can effectively realize the rapid separation of powder and foreign matter. For production with high requirements for powder, it can be installed at the feeding port, and can effectively realize the rapid separation of small clumps of powder, which is fast and practical.

[0033] When the utility model is used, it is only necessary to move the device to the bottom of the electric hoist, hoist the ton bag to the top, and fix the outlet of the ton bag to the feed port 9, so as to realize the rapid coarse screening of the ton bag raw materials and the separation of foreign matter and powder. The device is movable, easy to operate, flexible to control, and has good airtightness to prevent dust from appearing, and it is very convenient to quickly sample the whole bag of raw materials. Foreign matter or agglomeration may appear during the raw material feeding process. When the raw materials are inspected and accepted at the factory, the actual situation of the ton bag raw materials can be quickly and conveniently checked for abnormal ton bag raw materials. At the same time, during the raw material feeding process, this screen 2 is used to separate foreign matter from powder, ensuring that there is no foreign matter or agglomeration in the feeding.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
