detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Please refer to Fig. 1 to Fig. 5, the present invention provides a kind of shell pulverizer, comprises box body 10, hammer disc assembly 20, sieve piece 30, main shaft 40 and motor 50; Said box body 10 comprises upper box body 11 and with The lower box 12 matched with the upper box 11, the upper part of the upper box 11 is provided with a feed port 111, and the connection between the upper box 11 and the lower box 12 is provided with a recess 113 for The sieve 30 is placed; the hammer plate assembly 20 is rotatably arranged between the sieve 30 and the feed inlet 111 through the main shaft 40, and the hammer plate assembly 20 includes a plurality of hammer plates 21 , hammer plate bolts 22, hammer blades 23, and hammer blade bolts 24. The hammer plate 21 is provided with a plurality of first through holes 211 and second through holes 211 corresponding to the first through holes 211 on the position close to the peripheral edge. Through holes 212, each of the hammer pieces 23 is provided with a third through hole 231 and a fourth through hole 232, and the hammer plate bolts 22 pass through the first through hole 211 and the third through hole 231 in sequence The plurality of hammer discs 21 and the hammer blade 23 are fixed, and the hammer blade bolts 24 pass through the second through hole 212 and the fourth through hole 232 in turn to fix the hammer blade 23 to the The two sides of the hammer plate 21 form at least one group of hammer pieces 23 on the hammer pieces 23; the motor 50 is used to drive the main shaft 40 to rotate.

Through the pulverizer, the pulverization rate of shells can be improved, and at the same time, the pulverizer has a simple structure and is convenient for disassembly and maintenance.

In the embodiment, the main shaft 40 further includes a plurality of sleeves 41, and the sleeves 41 are arranged between two adjacent hammer plates 21, and are used to limit the contact between the hammer plate 21 and the adjacent hammer plates. The distance between the hammer disks 21 is such that the distance between the hammer disk 21 and the adjacent hammer disks 21 cannot be too close to affect the crushing effect.

In an embodiment, the gap between the sieve 30 and the hammer 223 is L, where 8≤L≤15mm. The size of the spacing affects whether it can be crushed sufficiently during crushing. If the spacing is too large, the shells are still in a state of larger particles after being crushed, which is of no use value; if the distance is too small, the sieve 30 is likely to be greatly damaged due to the extrusion of the shells by the hammer 23 . Due to the centrifugal force of the shells, large shells are deposited on the bottom of the sieve 30 and small shells are piled up on the top during the crushing process, which is not conducive to crushing and powder discharge. Simultaneously, this will cause the impact that most of the shells receive to be an eccentric impact, making the motion of the shells a rotational motion, which will make it difficult for the shells to break and cause a lot of waste. When the motor 50 is running at a high speed, the air around the hammer-disc assembly 20 and the main shaft 40 forms a circular motion around the axis of the main shaft 40 under the effect of rotation. Due to the circulation movement, the shells crushed into a certain particle size in the box 10 form a circulation layer. Shells with large particle size have a large mass and are subject to a large centrifugal force, so they are more likely to be distributed in the outer layer; materials with small particle size are less mass and subjected to less centrifugal force, so they are more likely to be distributed in the inner layer. The existence of the circulation layer affects the shell. crushing, reducing the crushing efficiency. Preferably, the gap L between the sieve 30 and the hammer 23 is 10mm. In this way, the small gap between the sieve 30 and the hammer 23 can reduce the influence of the circulation layer.

In an embodiment, the thickness of the hammer 23 is H, where 15≦H≦20mm. The hammer blade 23 is in direct contact with the shell, and the thickness of the hammer blade 23 affects the number of the hammer discs 21 in the relative distance. Preferably, the thickness of the hammer blade 23 is 20mm, which can ensure the impact on the shell during the crushing process. hammer hardness.

The sieve holes on the sieve sheet 30 determine the particle size range that can be screened out of the particles. In an embodiment, the sieve sheet 30 is distributed with small holes with a diameter of 5mm, and the distance between each small hole is 5mm. Like this, it can Screen out ultra-fine shell crushed particles. Simultaneously, the sieve 30 is used as a part in direct contact with the shell, and the sieve 30 is made of a material with good rigidity and wear resistance to ensure that the sieve 30 is not easily deformed or damaged under long-term work.

In the embodiment, the hammer disc assembly 20 includes multiple sets of equidistantly distributed hammer blades 23, and the number of equidistantly distributed hammer blades 23 on each hammer disc 21 is N, where 2≤N≤6 . The number of the hammer blades 23 also determines the efficiency of crushing. The number of crushing per unit time increases, the crushing efficiency increases, and the load of the machine increases. Preferably, three hammers are equidistantly distributed on each hammer plate 21. Sheet 23. Both sides of the hammer plate 21 are provided with the hammer blades 23, so that the number of the hammer blades 23 on one hammer plate 21 is 6, which enhances the crushing efficiency of shells.

The hammer piece 23 is used as a hammering part, and needs to be replaced after long-term wear and tear. If the hammering surface of one hammer piece 23 is single-sided, it will cause waste. In the embodiment, the hammer 23 adopts a symmetrical shape, so that after a long time of use, the hammer 23 can be replaced left and right when damaged, which can reduce the cost of the hammer 23 .

In the embodiment, the two sides of the hammer 23 are provided with serrations 233, and the end of the hammer 23 away from the third through hole 211 is provided with a tapered cutting blade 234, so that the hammer 223 can be enlarged The contact area with the shell, thereby improving the crushing efficiency of the shell.

In an embodiment, the rotating speed R of the main shaft 40 driven by the motor 50 ranges from 950r/min to 1150r/min. The higher the rotation speed of the main shaft 40, the better the pulverization effect, but the faster the rotation speed, the faster the loss of the hammer 23 will be. Preferably, the rotation speed of the main shaft 40 is 980r/min.

As shown in Figure 1, a first baffle 1111 and a second baffle 1112 are provided on the feed port 111. During operation, the first baffle 1111 is opened, the shells are put in, and after the placement is completed, the first baffle is closed. Plate 1111, open the second baffle 1112, so that the shells enter the box to be crushed, and the second baffle 1112 needs to be confirmed to be closed before putting the shells in. By setting the first baffle plate 1111 and the second baffle plate 1112 , it is possible to prevent the shells from splashing due to the high-speed rotation of the hammer 23 when the shells enter from the feeding port 111 .

In the embodiment, the lower end of the lower box 12 is provided with a discharge port 121, and the discharge port 121 is located directly below the screen 30, and the bottom of the lower box 12 is provided with anchor screws 122 for use in To fix the lower box body 12 , the motor 50 is arranged in the lower box body 12 . The motor 50 is placed in the lower box 12, which makes the overall structure more compact, occupies a smaller area, and is more convenient to transport. The specifications and models of the motor 50 affect the noise level during operation. In order to avoid excessive noise during operation, a pulverizer with a larger diameter and a lower rotating speed should be selected. Reducing the speed of the pulverizer can reduce the noise to a certain extent. For example, if the speed is reduced from 2550r/min to 2200r/min, the noise can be reduced by 2-3dB. Therefore, based on environmental protection and the impact on the human body, the noise during work should be reduced as much as possible to achieve the purpose of green production.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the present invention. within the scope of protection.
