Figure 4 The structure includes: 5 mills; mill inlet 51, mill outlet 52; material inlet 6; mill inlet 51 is directly connected to material inlet 6, there is no height difference at the inlet end and no buffer zone, so the sealing effect cannot be well achieved. During the operation of mill 5, the slurry inside rolls, which causes the slurry to continuously overflow from the connection between mill inlet 51 and material inlet 6, resulting in material waste, high maintenance difficulty and high cost. Utility Model Content

[0004] One object of this invention is to solve at least the aforementioned problems and / or defects, and to provide at least the advantages described below.

[0005] To achieve these objectives and other advantages according to this utility model, an impact-resistant protective plate for a mill is provided, comprising: a mill, having a mill inlet and a mill outlet, and further comprising...

[0006] The funnel inlet consists of a detachable upper structure and a lower structure. The upper structure is equipped with a dust suction pipe. The upper structure is in inclined contact with the material inlet and is inwardly folded. The lower structure is equipped with an outlet end and is fitted with a grooved fabric.

[0025] The following is a detailed description of this novel experimental device with reference to the accompanying drawings:

[0026] Figure 1-3 This invention discloses an impact-resistant protective plate for a mill, comprising a mill 2 with a mill inlet 21 and a mill outlet 22, and further comprising...

[0027] The funnel inlet 4 is composed of a detachably connected upper structure 42 and a lower structure 41. The upper structure 42 is provided with a dust suction pipe 43. The upper structure 43 is in inclined contact with the material inlet 1 and the upper structure 42 is inwardly folded. The lower structure 42 is provided with an outlet end 46. The lower structure 41 is fitted with a cloth with a groove.

[0028] The conveying pipeline 3 has one end connected to the outlet end 46 and the other end connected to the mill inlet 21;

[0029] A semi-circular anti-impact plate 30 is provided with a spiral structure 31 inside, and the semi-circular anti-impact plate 30 is installed close to the inside of the conveying pipe 3.

[0030] Working principle:

[0031] Before the material enters, the operator first installs the semi-circular anti-impact plate 30 tightly against the inner wall of the conveying pipe 3 and fixes it with bolts. Then, the lower end of the conveying pipe 3 is installed at the mill inlet 21. The upper end of the conveying pipe 3 is connected to the outlet end 42 of the lower half structure 41 of the funnel inlet 4. Then, the cloth is put on, so that the groove of the cloth, the outlet end 46 and the conveying pipe 3 are connected. The lower half structure 41 is connected to the upper half structure 42, and the cloth is fixed between the upper half structure 42 and the lower half structure 41.

[0032] The material enters the funnel inlet 4 through the material inlet 1 and falls onto the cloth inside the lower half structure 41, which decelerates the material for the first time. The material slides into the semi-arc anti-impact plate 30 through the outlet end 46. The semi-arc structure slows down the material speed, which decelerates the material for the second time. Finally, the impact of the material entering the mill inlet 21 is reduced, and the material enters the mill 2, completes the crushing, and leaves from the mill outlet 22.

[0033] in,

[0034] ①The design of the inwardly recessed upper structure 42 prevents materials from splashing or flying out of the funnel inlet 4. At the same time, the dust suction pipe 43 sucks away the dust raised, reducing environmental pollution during operation.

[0035] ② The cloth set on the inner wall of the lower half structure 41 can reduce the impact of materials on the funnel inlet 4, and can prevent materials from directly contacting the inner wall of the funnel inlet 4, thereby reducing the wear on the funnel inlet 4 and helping to extend its service life.

[0036] ③ The fabric is fixed to the lower half structure 41 by a detachable connection between the upper half structure 42 and the lower half structure 41. This connection method facilitates the replacement and installation of the fabric in case of damage.

[0037] ④ The semi-circular anti-impact plate 30, with its internal spiral structure 31, can withstand the wear caused by material impact, effectively extending the service life of the mill inlet 21.

[0038] In the above scheme, the conveying pipe 3 makes the material inlet 1 perpendicular to the mill inlet 21, and the thickness of the semi-arc anti-impact plate 2 is increased.

[0039] Working principle:

[0040] The conveying pipe 3 allows the high-speed material to be decelerated inside the semi-circular anti-impact plate 30, reducing impact and ensuring that the mill inlet 21 can withstand the impact from the material, thus reducing wear. The semi-circular anti-impact plate 30 is thickened to improve its impact resistance.

[0041] Among them, the semi-circular anti-impact plate 30 uses a new type of composite wear-resistant material to reduce the frequency of replacement and extend the service life.

[0042] As described above, the bottom of the upper structure 42 is provided with multiple sets of limiting grooves 45, which are composed of rectangular grooves 451 and cylindrical grooves 452.

[0043] The lower half structure 41 is provided with multiple sets of limiting blocks 44 at its top end. Each limiting block 44 is composed of a rectangular limiting block 441 and a cylindrical limiting block 442. The rectangular slot 451 is slidably connected to the rectangular limiting block 441, and the cylindrical slot 452 is engaged and fixed with the cylindrical limiting block 442.

[0044] The length of the rectangular slot 452 is slightly larger than the combined length of the rectangular limiting block 441 and the cylindrical limiting block 442.

[0045] Working principle:

[0046] The detachable connection between the upper structure 42 and the lower structure 41 is as follows: after placing the fabric to be used on the inner wall of the lower structure, the upper structure 42 is twisted by inserting the rectangular limiting block 441 into the rectangular limiting slot 451, so that the cylindrical limiting block 442 is inserted into the cylindrical slot 452, thereby fixing the upper structure 42 and the lower structure 41.

[0047] Similarly, when it is necessary to replace the fabric, simply rotate the upper half structure 42 in the opposite direction to make the cylindrical limiting block 442 disengage from the cylindrical slot 452, and then move it upward to separate the upper half structure 42 from the lower half structure 41.

[0048] This sliding and snap-fit ​​connection method ensures that the device is not easily detached during operation, and also makes it simple and convenient for operators to replace or test the device.

[0049] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
