Description

Technical Field

[0001] This utility model belongs to the field of metal processing technology, and specifically relates to an aluminum phosphide pulverizing device for producing aluminum phosphide powder. Background Technology

[0002] Aluminum phosphide has many applications in agriculture, industry, and daily life. To meet the needs of different fields, aluminum phosphide raw materials need to be crushed and prepared into aluminum phosphide powder. In order to ensure that the equipment can crush all aluminum phosphide into the required size, existing aluminum phosphide crushing equipment is equipped with a conveyor belt to transport aluminum phosphide that does not meet the size requirements, so that the aluminum phosphide that does not meet the size requirements can pass through the crushing mechanism again. However, when the conveyor belt transports aluminum phosphide, there will be a situation where aluminum phosphide enters the groove where the conveyor belt is installed, resulting in some aluminum phosphide accumulating inside the equipment, causing waste and increasing the difficulty of cleaning the equipment. Utility Model Content

[0019] Please see Figure 1-5This utility model provides the following technical solution: an aluminum phosphide pulverizing device for producing aluminum phosphide powder, including a shell 1, a pulverizing roller 2, an electric push rod 4 and a sieve 6, and a temporary storage bin 5. The shell 1 is provided with a pulverizing bin 13 and a feeding channel 12. The temporary storage bin 5 is rotatably installed on the pulverizing bin 13. Several storage troughs 51 are evenly opened on the temporary storage bin 5. Pulverizing rollers 2 are provided on both sides of the channel of the pulverizing bin 13. A drive gear 54 is installed on the temporary storage bin 5. An electric gear 53 that meshes with the drive gear 54 is installed on the shell 1. A sieve 6 that cooperates with the temporary storage bin 5 is slidably installed on the bottom opening of the shell 1. Two electric push rods 4 that cooperate with the sieve 6 are provided on the bottom opening of the shell 1.

[0020] The feed channel 12 is used to feed the aluminum phosphide to be crushed into the interior of the device. The crushing chamber 13 is used to install the crushing roller 2, which is used to crush the aluminum phosphide. The channel of the crushing chamber 13 is inclined on both sides of the crushing roller 2 to ensure that the aluminum phosphide can move smoothly to the position between the crushing roller 2, thus ensuring the crushing effect of the crushing roller 2 on the aluminum phosphide. The storage tank 51 is used to transport the aluminum phosphide. The aluminum phosphide entering the feed channel 12 will enter the crushing chamber 13 through the storage tank 51, realizing the transport of aluminum phosphide. The temporary storage tank 5 is rotatably installed on the crushing chamber 13. The temporary storage tank 5 is connected to the electric gear 53 through the drive gear 54. When the electric gear 53 is started, the drive gear Drive gear 54 rotates under the action of electric gear 53, which in turn drives the temporary storage bin 5 to rotate. The diameter of the gear part of electric gear 53 is smaller than the diameter of drive gear 54, ensuring that electric gear 53 can smoothly drive the temporary storage bin 5 to rotate. The temporary storage bin 5 is equipped with several storage troughs 51. During the rotation of the temporary storage bin 5, a storage trough 51 is always connected to the feed channel 12, ensuring that the rotation of the temporary storage bin 5 does not affect the conveying of aluminum phosphide to be processed and the discharge of crushed aluminum phosphide. After the crushed aluminum phosphide enters the lowermost storage trough 51, the sieve 6 will sieve the aluminum phosphide that falls into the lowermost storage trough 51, and any aluminum phosphide that is not completely crushed will be sieved. The crushed aluminum phosphide is sieved through the screen 6. During the rotation of the temporary storage chamber 5, the aluminum phosphide solids sieved through the screen 6 are carried along by the storage trough 51. The aluminum phosphide sieved through the screen 6 is moved by the rotating temporary storage chamber 5 to the top of the crushing chamber 13. The storage trough 51 above the crushing chamber 13 then re-feeds the aluminum phosphide sieved through the screen 6 into the crushing chamber 13, achieving further crushing of the aluminum phosphide and ensuring that the device can crush all the aluminum phosphide to the appropriate size. The screen 6 is slidably installed on the bottom opening of the outer casing 1. During the rotation of the electric push rod 4, the electric push rod 4 pushes the screen 6. As the electric push rod 4 rotates, the electric push rod... When the pusher 4 releases its push on the screen 6, the screen 6 falls rapidly. During the rotation of the electric pusher 4, the screen 6 reciprocates on the groove where it is installed. The reciprocating motion of the screen 6 vibrates the aluminum phosphide on it, ensuring the sieving effect of the screen 6 on the aluminum phosphide. The shape of the screen 6 matches the temporary storage bin 5, ensuring that the aluminum phosphide sieved by the screen 6 does not accumulate between the temporary storage bin 5 and the screen 6, and ensuring that the movement of the screen 6 is not hindered by the aluminum phosphide, thus ensuring the sieving effect of the screen 6 on the aluminum phosphide. The shape of the screen 6 ensures that the temporary storage bin 5 can scrape all the incompletely crushed aluminum phosphide away from the screen 6 during the rotation process.

[0021] Specifically, the inner wall of the temporary storage chamber 5 is provided with several limiting rings 52, and the side wall of the crushing chamber 13 is provided with grooves that cooperate with the limiting rings 52.

[0022] The matching groove of the limiting ring 52 plays a limiting role, ensuring the stability of the temporary storage chamber 5 after it is rotated and installed on the crushing chamber 13. The temporary storage chamber 5 is provided with several limiting rings 52, which further improves the stability of the temporary storage chamber 5 after it is installed on the crushing chamber 13. The shape of the limiting ring 52 ensures that aluminum phosphide will not enter the interior of the groove that matches the limiting ring 52 during the movement, ensuring that aluminum phosphide will not hinder the rotation of the temporary storage chamber 5.

[0023] Specifically, the cross-sectional shape of the limiting ring 52 is quadrilateral, and the edge of the limiting ring 52 faces upward.

[0024] The cross-sectional shape and orientation of the limiting ring 52 ensure that aluminum phosphide will not accumulate on the limiting ring 52 during its movement inside the storage tank 51, thus ensuring that the limiting ring 52 will not obstruct the movement of aluminum phosphide. The depth of the groove that mates with the limiting ring 52 is greater than half the thickness of the limiting ring 52. The depth of the groove that mates with the limiting ring 52 ensures the stability of the limiting ring 52 and the groove that mates with it.

[0025] Specifically, the top and bottom of the protruding sidewall of the screen 6 are sloped, and the bottom of the groove where the screen 6 is installed is also sloped.

[0026] The raised top surface shape of the side wall of the screen 6 can prevent aluminum phosphide from accumulating on the side wall protrusion of the screen 6, ensuring that the movement of the screen 6 is not obstructed. The bottom shape of the groove where the screen 6 is installed ensures that aluminum phosphide passing through the screen 6 will not accumulate at the bottom of the groove where the screen 6 is installed. The raised bottom surface shape of the side wall of the screen 6 reduces the damage to the screen 6 when it comes into contact with the bottom of the groove where the screen 6 is installed.

[0027] Specifically, a spring telescopic rod 61 connected to the screen 6 is provided on the side wall of the groove where the screen 6 is installed.

[0028] During the process of the screen 6 being pushed by the electric push rod 4, the spring telescopic rod 61 will begin to extend and retract under the action of the screen 6. After the electric push rod 4 releases the pushing action on the screen 6, the extended and retracted spring telescopic rod 61 returns to its original state. The spring telescopic rod 61 returning to its original state plays the role of increasing the frequency of the reciprocating movement of the screen 6, thereby improving the screening effect of the screen 6 on aluminum phosphide.

[0029] Specifically, an observation window 11 is provided on the side wall of the outer shell 1 at the position corresponding to the temporary storage compartment 5, and the side wall of the temporary storage compartment 5 corresponding to the observation window 11 is a transparent structure.

[0030] Users can observe the condition inside the storage tank 51 through the transparent structure of the observation window 11 and the temporary storage bin 5, which makes it easier for users to determine the amount of aluminum phosphide accumulated on the sieve 6 and avoid the sieve 6's sieving effect on aluminum phosphide due to excessive accumulation of aluminum phosphide on the sieve 6.

[0031] Specifically, the outer casing 1 is equipped with a blower 3 that communicates with the feed channel 12, and the outer casing 1 is equipped with a water tank 31 that is connected to the blower 3.

[0032] The blower 3 can remove the dust generated during the operation of the device. The dust removed by the blower 3 will be sent into the water tank 31. The airflow entering the water tank 31 will be cleaned by the water in the water tank 31. The cleaned airflow will be discharged from the water tank 31, and the dust will dissolve in the water, thus preventing the dust removed by the blower 3 from affecting the external environment. The bottom of the pipe connected to the blower 3 extends into the bottom of the water in the water tank 31, ensuring the cleaning effect of the water in the water tank 31 on the airflow containing dust. A filter screen is provided on the channel connecting the blower 3 and the outer casing 1 to prevent the aluminum phosphide from being drawn out of the outer casing 1 by the blower 3 during the movement, thus preventing damage to the blower 3.

[0033] The working principle and usage process of this utility model are as follows: The crushing roller 2 and electric push rod 4 are activated, and aluminum phosphide is fed into the interior of the outer casing 1 through the feed channel 12. After entering the crushing chamber 13, the aluminum phosphide is crushed by the crushing roller 2. The crushed aluminum phosphide falls onto the sieve 6. During the rotation of the electric push rod 4, the sieve 6 reciprocates under the action of the electric push rod 4. The reciprocating sieve 6 sieves the aluminum phosphide on the sieve 6. The electric gear 53 is activated, and the temporary storage chamber 5 is rotated by the electric gear 53 in cooperation with the drive gear 54. The temporary storage chamber 5 rotates along with the aluminum phosphide on the sieve 6. As the temporary storage chamber 5 rotates, the sieved aluminum phosphide is fed back into the crushing chamber 13, ensuring the crushing effect of the device on aluminum phosphide.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
