Description

Technical Field

[0043] Refer to the following Figure 1-Figure 10 The invention will now describe a raw material mixing and grinding device for seasoning processing.

[0044] A raw material mixing and grinding device for seasoning processing is suitable for preparing powder, comprising an upper cover 100 and a lower cover 110, the upper cover 100 and the lower cover 110 are buckled together to form a sealed cavity 120 therebetween, a feed pipe 101 is connected at an eccentric position of the upper cover 100, the angle between the feed pipe 101 and the upper cover 100 is an acute angle, and a vertical plane where the feed pipe 101 is located is tangent to the connection position, that is, the feed pipe 101 is obliquely arranged on the upper cover 100, and a discharge pipe 102 is vertically connected to the center position of the upper cover 100. A crushing ring plate 200 is rotatably arranged in the cavity 120, and the axis of the crushing ring plate 200 coincides with the axis of the upper cover 100 and the lower cover 110. A crushing cavity 210 is provided inside the crushing ring plate 200. A feed ring groove 230 is provided on the upper end surface of the crushing ring plate 200, and the feed ring groove 230 is connected with the feed pipe 101 of the upper cover 100. The material enters the crushing cavity 210 through the feed pipe 101 for crushing. A plurality of crushing knives 240 are arranged on the feed ring groove 230. When the material passes through the feed ring groove 230, it will be initially crushed by the crushing knives 240. A discharge groove 250 is also provided on the crushing ring plate 200, and the discharge groove 250 is connected with the discharge pipe 102 of the upper cover 100.

[0045] A plurality of air nozzles 220 with the same inclination direction are evenly distributed on the outer periphery of the crushing ring plate 200, and the air nozzles 220 connect the crushing chamber 210 and the cavity 120, and the side wall of the lower cover 110 is connected with an inclined air inlet pipe 111, and the inclination direction of the air inlet pipe 111 is the same as the inclination direction of the air nozzles 220. The air inlet pipe 111 injects fast-flowing gas into the cavity 120, and the gas surrounds the outer periphery of the crushing ring plate 200. The gas enters the crushing chamber 210 through the air nozzles 220 on the outer periphery of the crushing ring plate 200. Due to the inclined setting of the air nozzles 220, the gas entering the crushing chamber 210 rotates along the crushing chamber 210, thereby driving the material in the crushing chamber 210 to rotate. The material will continuously collide during the rotation process, thereby performing secondary crushing on the material, and the gas entering the crushing chamber 210 will be discharged through the discharge pipe 102 to form a cycle. When the material is crushed to a certain size and its weight is reduced, it will be carried out by the gas flowing out of the discharge pipe 102.

[0046] It should be noted that, since the air inlet pipe 111 is also inclined, and the inclination direction is the same as the inclination direction of the air nozzle 220, the fast-flowing gas entering the air inlet pipe 111 can blow the crushing ring plate 200 to rotate, and the rotation direction is the same as the rotation direction of the gas in the crushing chamber 210. Since the crushing ring plate 200 is rotating and the rotation direction of the crushing ring plate 200 is the same as the rotation direction of the gas, the relative rotation speed between the material and the crushing ring plate 200 can be reduced, thereby reducing the wear of the material on the crushing ring plate 200. Compared with the arrangement in the prior art that the crushing ring plate 200 is fixed in the chamber, the service life of the crushing ring plate 200 can be improved. At the same time, the crushing knife 240 on the annular feed groove of the crushing ring plate 200 can preliminarily crush the material, thereby improving the overall crushing effect of the material.

[0047] An adjustment component is also provided in the crushing ring plate 200, and the adjustment component can adjust the opening size of the discharge trough 250. The adjustment component is linked with the crushing knife 240 to adjust the position of the crushing knife 240. The specific configuration of the adjustment component is as follows:

[0048] When the material holding amount in the crushing chamber 210 (the material holding amount refers to the amount of all materials in the crushing chamber 210) is large, the high-speed flow of gas blows the crushing ring plate 200 to rotate at a slower speed than the normal material holding amount. At this time, the materials in the crushing chamber 210 collide with each other at a higher frequency, thereby improving the crushing effect in the crushing chamber 210. Therefore, the adjustment component adjusts the position of the crushing knife 240 so that the crushing knife 240 is in an inclined state (the inclined state is relative to the direction of material feeding). The material collides with the crushing knife 240 in an inclined state, which weakens the crushing effect of the crushing knife 240, but can reduce the wear of the crushing knife 240, thereby increasing the service life of the crushing knife 240. When the material holding amount is large, the crushing effect of the crushing knife 240 is weakened, but the crushing effect of the crushing chamber 210 is enhanced. Overall, there is no significant change compared to the crushing effect at the normal material holding amount. At the same time, the material holding amount exceeds the normal amount, and the regulating component increases the opening of the discharge chute 250, so that the crushed material can be discharged from the crushing chamber 210 faster, thereby gradually approaching the normal material holding amount.

[0049] When the amount of material held in the crushing chamber 210 is small, the high-speed gas drives the crushing ring plate 200 to rotate faster than the normal material holding amount. At this time, the collision frequency of the materials in the crushing chamber 210 is low, thereby weakening the crushing effect of the crushing chamber 210. Therefore, the adjustment component adjusts the position of the crushing knife 240 so that the crushing knife 240 is in a vertical state. When the material passes through the feeding ring groove 230, the material will vertically collide with the blade 241 of the crushing knife 240. At this time, the crushing effect of the material is better, but the degree of wear on the crushing knife 240 is greater, thereby The service life of the crushing knife 240 is reduced. When the material holding amount is small, the crushing effect of the crushing chamber 210 is weakened. The adjustment component adjusts the position of the crushing knife 240 to improve the crushing effect of the crushing knife 240, thereby compensating for the overall crushing effect, so that the crushing effect when the material holding amount is small can still be similar to the crushing effect when the material holding amount is normal. At the same time, the adjustment component reduces the opening of the discharge chute 250, so that the less material in the crushing chamber 210 is slowly discharged. With the continuous delivery of materials from the feed port, the material holding amount in the crushing chamber 210 gradually returns to normal.

[0050] By providing a rotatable crushing ring plate 200, and the rotation direction is the same as the rotation direction of the material, the relative rotation speed between the material and the crushing ring plate 200 is reduced, thereby reducing the wear of the crushing ring plate 200 by the material, and increasing the service life of the crushing ring plate 200. At the same time, by providing an adjustment component, the adjustment component can adjust the opening size of the discharge chute 250 and the position of the crushing knife 240, so as to self-adapt to the material crushing at different material holding amounts under the premise of ensuring the overall crushing effect, and make the material holding amount in the crushing chamber 210 gradually tend to normal.

[0051] Specifically, the adjustment assembly in this embodiment includes a rotating ring 300 and a plurality of crescent-shaped baffles 310. The rotating ring 300 is coaxially and rotatably arranged on the upper end surface of the crushing ring plate 200. The inner circumference of the rotating ring 300 has teeth 301, and the plurality of crescent-shaped baffles 310 are arranged in a circular array and rotatably arranged on the edge of the discharge trough 250. The rotating ring 300 and the plurality of crescent-shaped baffles 310 are in the same plane. A gear 311 is arranged on one end of the plurality of crescent-shaped baffles 310 that are rotatably connected. The teeth 301 on the inner circumference of the rotating ring 300 are arranged on the inner circumference of the crushing ring plate 200. The tooth 301 is meshed with the gear 311. When the rotating ring 300 rotates around its own axis, the rotating ring 300 can drive the crescent-shaped baffle 310 to rotate around the rotation center, so that the other end of the crescent-shaped baffle 310 moves. When the other ends of several crescent-shaped baffles 310 are close to each other, the opening of the discharge chute 250 becomes smaller, that is, the material passes through the opening formed by the other ends of several crescent-shaped baffles 310. When the other ends of several crescent-shaped baffles 310 are away from each other, the opening of the discharge chute 250 will increase.

[0052] For example Figure 8As shown, when the rotating ring 300 rotates clockwise, the teeth 301 on the inner circumference of the rotating ring 300 drive the gear 311 to rotate clockwise, and the gear 311 drives the crescent-shaped baffle 310 to rotate, and the other ends of the several crescent-shaped baffles 310 move away from each other, thereby increasing the opening of the discharge trough 250; when the rotating ring 300 rotates counterclockwise, the teeth 301 on the inner circumference of the rotating ring 300 drives the gear 311 to rotate counterclockwise, and the gear 311 drives the crescent-shaped baffle 310 to rotate, and the other ends of the several crescent-shaped baffles 310 move closer to each other, thereby reducing the opening of the discharge trough 250.

[0053] More specifically, to realize the rotation of the rotating ring 300, the present invention adopts the following structure:

[0054] A first connecting rod 320 is hinged on the rotating ring 300, and a plurality of slide grooves 260 are provided on the upper end surface of the crushing ring plate 200. Elastic members 340 are arranged in the plurality of slide grooves 260. Each slide groove 260 is inclined and arranged in a uniform circumferential array outside the rotating ring 300. The other end of the first connecting rod 320 is slidably arranged in the slide groove 260 and connected to the elastic member 340. The initial state of the first connecting rod 320 (the initial state refers to the state where the crushing ring plate 200 is not rotating) When the first connecting rod 320 is in the middle position of the chute 260 and the elastic member 340 is in the original length state, the second connecting rod 330 is hinged on one end of the first connecting rod 320 located in the chute 260, and the other end of the second connecting rod 330 is hinged to the crushing knife 240, and the other end of the crushing knife 240 is hinged to the upper end surface of the crushing ring plate 200, so that the crushing knife 240 is just located between the feeding ring grooves 230, and the material can be preliminarily crushed by the crushing knife 240 when passing through the feeding ring grooves 230.

[0055] like Figure 7 and Figure 8 As shown in the figure, when the crushing ring plate 200 rotates, the first connecting rod 320 is subjected to centrifugal force, and one end of the first connecting rod 320 slides in the slide groove 260 in the direction away from the rotating ring 300. If the amount of material held in the crushing chamber 210 is small, the crushing ring plate 200 rotates faster. At this time, the centrifugal force on the first connecting rod 320 increases, so that one end of the first connecting rod 320 overcomes the pulling force of the elastic member 340 and stretches, and the other end of the first hinged rod pulls the rotating ring 300 to rotate around its own axis, and the inner circumference of the rotating ring 300 is increased. The teeth 301 drive the gear 311 to rotate, and the other ends of the several crescent-shaped baffles 310 are close to each other, thereby reducing the opening of the discharge chute 250. At the same time, the second connecting rod 330 hinged to the first connecting rod 320 pulls the crushing knife 240. The crushing knife 240 rotates with the hinge point hinged on the crushing ring plate 200 as the rotation center. The crushing knife 240 is gradually distributed along the radial direction of the crushing ring plate 200, so that the material passing through the feed ring groove 230 can vertically collide with the blade 241 of the crushing knife 240, thereby enhancing the crushing effect of the crushing knife 240.

[0056] It should be noted that the elastic member 340 in the present invention is a tension spring.

[0057] In a further embodiment, a filter screen 221 is provided on the air nozzle 220 in this embodiment, and the filter screen 221 can intercept solid impurities in the gas entering the crushing chamber 210, thereby preventing the solid impurities in the gas from affecting the crushing of the material inside the crushing chamber 210.

[0058] Specifically, the crushing ring plate 200 in this embodiment is surrounded by an upper liner 201, a side liner 203 and a lower liner 204, which are fixedly connected. A first bearing 202 is arranged between the upper liner 201 and the upper cover 100, and the first bearing 202 rotatably connects the upper liner 201 and the upper cover 100, while a second bearing 205 is arranged between the lower liner 204 and the lower cover 110, and the second bearing 205 rotatably connects the lower liner 204 and the lower cover 110. Through the arrangement of the first bearing 202 and the second bearing 205, the crushing ring plate 200 formed by the upper liner 201, the side liner 203 and the lower liner 204 can rotate better, and the upper liner 201, the side liner 203 and the lower liner 204 rotate synchronously, thereby reducing the wear of the upper liner 201, the side liner 203 and the lower liner 204.

[0059] In a further embodiment, an air intake assembly is provided on the side wall of the feed pipe 101, and the air intake assembly can transport gas into the feed pipe 101. The transported gas drives the material in the feed pipe 101 to quickly enter the crushing chamber 210, and at the same time gives kinetic energy to the material, so that the material can collide with the crushing knife 240 with a greater impact force, thereby enhancing the crushing effect of the material.

[0060] Specifically, the air intake assembly includes an air compressor 130 and a connecting pipe 140 . The connecting pipe 140 is connected to the side wall of the feed pipe 101 . The other end of the connecting pipe 140 is connected to the air compressor 130 . The air compressor 130 transports the gas to the feed pipe 101 through the connecting pipe 140 .

[0061] More specifically, a support base 112 is disposed at the bottom of the lower cover 110 , and the support base 112 is used to support the entire lower cover 110 and the upper cover 100 , so as to ensure that the upper cover 100 and the lower cover 110 are in a stable state during operation.

[0062] The specific working process of the raw material mixing and grinding equipment for seasoning processing provided by the present invention is described in combination with the above embodiments:

[0063] Preparation:

[0064] High-speed flowing gas is introduced into the air inlet pipe 111, and the gas enters the cavity 120 through the air inlet pipe 111. Since the air inlet pipe 111 is inclined, the high-speed flowing gas blows toward the crushing ring plate 200 to cause the crushing ring plate 200 to rotate. The gas also enters the crushing chamber 210 through the air nozzle 220. Since the inclination direction of the air nozzle 220 is the same as the inclination direction of the air inlet pipe 111, the rotation direction of the gas entering the crushing chamber 210 is the same as the rotation direction of the crushing ring plate 200. The gas is discharged to the discharge pipe 102 through the discharge trough 250 in the crushing chamber 210. The air inlet pipe 111 continuously transports the gas, and the gas is discharged from the discharge pipe 102.

[0065] Feed materials:

[0066] The air compressor 130 is turned on. The air compressor 130 delivers gas to the connecting pipe 140. The gas enters the feed pipe 101 through the connecting pipe 140, and the material is added to the feed pipe 101. When the material is transported to the feed ring groove 230 by the gas at high speed, the material collides with the crushing knife 240 at high speed, and the material is preliminarily crushed by the crushing knife 240. After the preliminarily crushed material, it enters the crushing chamber 210. The high-speed rotating gas in the crushing chamber 210 drives the material to rotate at high speed. The materials collide with each other and are crushed. The larger part of the material is subjected to a larger centrifugal force and thus moves away from the discharge trough 250, and the smaller part of the material is close to the discharge trough 250. The completely crushed material passes through the discharge trough 250 through the flowing gas and enters the discharge pipe 102, thereby being discharged from the crushing chamber 210.

[0067] When the amount of material held in the crushing chamber 210 is large:

[0068] When the amount of material held in the crushing chamber 210 is large, the rotation speed of the crushing ring plate 200 will be reduced. At this time, the frequency of collision between more materials is high, so that the material crushing effect in the crushing chamber 210 is better. Since the crushing ring plate 200 rotates slowly, the centrifugal force on the first connecting rod 320 is reduced, so that the originally stretched elastic member 340 is shortened, and the elastic member 340 pulls the first connecting rod 320 to slide in the slide groove 260 toward the rotating ring 300. The first connecting rod 320 pulls the second connecting rod 330, and the second connecting rod 330 pulls the crushing knife 240, so that the crushing knife 240 becomes tilted, so that the subsequent material collides with the crushing knife 240 at an angle, thereby reducing the wear of the crushing knife 240. At the same time, the first connecting rod 320 pulls the rotating ring 300 to rotate, and the teeth 301 on the inner circumference of the rotating ring 300 drive the plurality of gears 311 to rotate, and the plurality of gears 311 drive the other ends of the plurality of crescent-shaped baffles 310 to move away from each other, thereby increasing the opening of the discharge trough 250, so that the completely crushed material in the crushing chamber 210 is quickly discharged from the crushing chamber 210, thereby gradually reducing the material holding capacity of the crushing chamber 210. When the material holding capacity of the crushing chamber 210 returns to normal, the size of the opening of the discharge trough 250 and the crushing knife 240 return to normal.

[0069] When the amount of material in the crushing chamber 210 is small:

[0070] When the material holding amount in the crushing chamber 210 decreases, the rotation speed of the crushing ring plate 200 will increase, and the smaller material holding amount will lead to a lower collision frequency between materials, thereby weakening the material crushing effect in the crushing chamber 210. At this time, due to the increase in the centrifugal force on the first connecting rod 320, the first connecting rod 320 slides in the groove to pull the second connecting rod 330, and the second connecting rod 330 pulls the crushing knife 240, so that the crushing knife 240 is distributed radially along the crushing ring plate 200. When the subsequent material passes through the feed ring groove 230, the material collides vertically on the blade 241 of the crushing knife 240, thereby enhancing the initial crushing effect of the material. At the same time, the first connecting rod 320 pulls the rotating ring 300 to rotate, and the teeth 301 on the inner circumference of the rotating ring 300 drive the several gears 311 to rotate, and the gears 311 drive the other ends of the several crescent-shaped baffles 310 to approach each other, thereby reducing the opening of the discharge chute 250, so that the material is crushed for a longer time in the crushing chamber 210, and at the same time, the material holding amount in the crushing chamber 210 can be gradually increased. When the material holding amount returns to normal, the opening size of the discharge chute 250 and the crushing knife 240 gradually return to normal.
