Description

Technical Field

[0001] The invention belongs to the technical field of silkworm feed processing, and particularly relates to a silkworm feed additive agglomeration breaking device and a use method thereof. Background Art

[0002] Common mineral additives used in silkworm feed, such as calcium carbonate and calcium hydrogen phosphate, are prone to moisture absorption and agglomeration. Calcium carbonate readily absorbs moisture from the air, and when the moisture content reaches a certain level, the particles adhere to each other and form lumps. Calcium hydrogen phosphate has a similar property, easily agglomerating when exposed to moisture, affecting its uniform distribution in the feed and, in turn, hindering the silkworms' absorption of minerals.

[0003] Many existing crushers use blade-type crushing. When crushing silkworm feed additives, they are often directly crushed into powder. Since different silkworm feed additives have different requirements for the particle size after crushing, it is difficult to meet the particle size requirements if they are directly crushed into powder. Summary of the Invention

[0004] The purpose of the present invention is to provide a silkworm feed additive agglomeration breaking device and a use method thereof, which can use magnetic collision to break up the silkworm feed additive to meet the required particle size.

[0005] The technical solutions adopted by the present invention are as follows:

[0006] A silkworm feed additive agglomeration breaking device comprises a box body, an end cover is mounted on the top of the box body, a feeding assembly is fixedly connected to the top surface of the end cover, a lifting plate is slidably connected to the inner cavity of the box body, a plurality of balls are arranged on the top surface of the lifting plate, and a transmission assembly is arranged on the bottom surface of the inner cavity of the box body;

[0007] The side wall of the box body is fixedly connected to a first annular shell, the outer wall of the box body is located in the first annular shell and is fixedly connected to a plurality of first electromagnetic blocks, the top surface of the end cover is fixedly connected to a second annular shell, and the top surface of the end cover is located in the second annular shell and is fixedly connected to a plurality of second electromagnetic blocks.

[0008] Furthermore, the feed assembly includes a feed pipe fixedly connected to the top surface of the end cover, a discharge pipe is fixedly connected to the side wall of the feed pipe, and a control valve is installed at the connection between the feed pipe and the discharge pipe.

[0009] Furthermore, the transmission assembly includes two support plates fixedly connected to the bottom surface of the inner cavity of the box, a crankshaft is rotatably connected between the two support plates, a motor is installed on the side wall of one of the support plates, the output end of the motor is fixedly connected to the crankshaft, a sleeve is rotatably connected to the side wall of the crankshaft, a connecting rod is fixedly connected to the side wall of the sleeve, and the top end of the connecting rod is hinged to the lifting plate.

[0010] Furthermore, a plurality of limiting rods are fixedly connected to the bottom surface of the lifting plate, an annular plate is fixedly connected to the inner wall of the box located below the lifting plate, and the limiting rods pass through the annular plate and are movably connected thereto.

[0011] Furthermore, an annular groove is provided on the side wall of the lifting plate, a sealing ring is installed in the annular groove, and the sealing ring is against the inner wall of the box.

[0012] Furthermore, the side wall of the end cover is movably connected with a plurality of evenly distributed bolts, and the bolts are threadedly connected to the box body.

[0013] Furthermore, the box body and the inner wall of the end cover are respectively fixedly connected with anti-collision pads.

[0014] Furthermore, the first electromagnetic block and the second electromagnetic block are distributed in a circular array with the central axis of the box as the center.

[0015] A method for using a device for breaking up agglomerates of silkworm feed additives, the method comprising the following steps:

[0016] S1: First, connect the feed pipe to the external hopper, and then control the feed amount of the additive through the control valve so that the appropriate amount of additive is discharged into the box;

[0017] S2: The motor is then started, which drives the crankshaft to rotate. The height displacement difference generated by the crankshaft rotation is used to drive the lifting plate up and down through the connecting rod, so that the lifting plate drives the balls and additives to shake up and down inside the box. During the shaking process, the balls collide with the additives to cause initial breakage.

[0018] S3: Then, the first electromagnetic block and the second electromagnetic block are energized to generate a strong magnet. The first electromagnetic block and the second electromagnetic block are energized in an interlaced manner. When energized once, only one of the two adjacent first electromagnetic blocks or second electromagnetic blocks is energized to generate a strong magnet.

[0019] S4: When the first or second electromagnetic block is energized, the strong magnetism generated rapidly attracts the balls to the inner wall of the box.

This step is repeated to complete the breaking up of the agglomerated additives.

[0020] S5: After the additive is crushed, the control valve is turned to connect the box with the discharge pipe, and the additive is extracted by the external negative pressure to complete the discharge.

[0021] The technical effects achieved by the present invention are:

[0022] The silkworm feed additive agglomeration breaking device and its use method of the present invention adopt a strong magnetic adsorption ball method to break up the silkworm feed additive through the collision between the ball and the silkworm feed additive, so as to decompose the agglomerated silkworm feed into smaller particles. By controlling the breaking time, the particle size requirements of different needs can be met. The longer the breaking time, the smaller the particle size, and the shorter the breaking time, the larger the particle size. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following examples. It should be understood that the following text is only used to describe one or more specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0033] Example 1:

[0034] like Figure 1-Figure 7As shown, a device for breaking up agglomerates of silkworm feed additives comprises a housing 1, an end cover 19 is mounted on the top of the housing 1, a feeding assembly is fixedly connected to the top surface of the end cover 19, a lifting plate 5 is slidably connected to the inner cavity of the housing 1, a plurality of balls 6 are arranged on the top surface of the lifting plate 5, and the balls 6 are made of metal, and are generally made of ferromagnetic materials such as iron, cobalt, and nickel. A transmission assembly is arranged on the bottom surface of the inner cavity of the housing 1;

[0035] The side wall of the box body 1 is fixedly connected to a first annular shell 7, the outer wall of the box body 1 is located inside the first annular shell 7 and is fixedly connected to a plurality of first electromagnetic blocks 8, the top surface of the end cover 19 is fixedly connected to a second annular shell 9, and the top surface of the end cover 19 is located inside the second annular shell 9 and is fixedly connected to a plurality of second electromagnetic blocks 10.

[0036] like Figure 1 and Figure 2 As shown, the feed assembly includes a feed pipe 2 fixedly connected to the top surface of the end cover 19, a discharge pipe 3 fixedly connected to the side wall of the feed pipe 2, and a control valve 4 installed at the connection between the feed pipe 2 and the discharge pipe 3.

[0037] During the discharge process, the lifting plate 5 continuously rises and falls, facilitating the upward movement of the silkworm feed additive, while the balls 6 simultaneously descend under their own gravity. Furthermore, the use of negative pressure suction discharge prevents the generation of dust that could pollute the work environment and harm the health of operators. Negative pressure suction discharge creates a negative pressure within the discharge pipe 3, drawing the material into it. This reduces contact between the material and the outside air, effectively suppressing the rise of dust and maintaining a clean work environment.

[0038] like Figure 2 and Figure 5 As shown, the transmission assembly includes two support plates 11 fixedly connected to the bottom surface of the inner cavity of the box body 1, and a crankshaft 13 is rotatably connected between the two support plates 11. A motor 12 is installed on the side wall of one of the support plates 11, and the output end of the motor 12 is fixedly connected to the crankshaft 13. The side wall of the crankshaft 13 is rotatably connected to a sleeve 14, and the side wall of the sleeve 14 is fixedly connected to a connecting rod 15, and the top end of the connecting rod 15 is hinged to the lifting plate 5.

[0039] The rotational motion of the crankshaft 13 is precisely converted into the reciprocating linear motion of the lift plate 5 via the connecting rod 15. With each complete rotation of the crankshaft 13, the lift plate 5 completes an up-and-down reciprocating motion. This motion pattern is stable and predictable, enabling accurate control of the lift plate 5's dwell time and speed at different positions. Furthermore, during its rotation, the crankshaft 13 is able to evenly transmit power to the lift plate 5. Due to the structural characteristics of the crankshaft 13, the torque generated during rotation is relatively stable, without significant force fluctuations. This ensures that the force exerted on the lift plate 5 during the lifting process is relatively uniform, preventing shaking or jamming of the lift plate 5 due to uneven force.

[0040] like Figure 2 As shown, the bottom surface of the lifting plate 5 is fixedly connected to a plurality of limiting rods 16. An annular plate 17 is fixedly connected to the inner wall of the box body 1 below the lifting plate 5. The limiting rods 16 pass through the annular plate 17 and are movably connected to it. The limiting rods 16 can be provided to vertically limit the lifting plate 5, ensuring the stability of the lifting plate 5 during the lifting process.

[0041] like Figure 6 As shown, the side wall of the lifting plate 5 is provided with an annular groove, in which a sealing ring 18 is mounted. The sealing ring 18 abuts against the inner wall of the box body 1. Since the sealing ring 18 is made of a flexible material, its flexibility and elasticity allow it to adhere to the inner wall of the box body 1 during the upward and downward movement of the lifting plate 5, preventing small silkworm feed additives from leaking through the gap and thus achieving a sealing effect.

[0042] like Figure 7 As shown, the side wall of the end cover 19 is movably connected to a number of evenly distributed bolts 20, which are threadedly connected to the box body 1. The bolts 20 serve as a connection between the end cover 19 and the box body 1. When the interior of the box body 1 needs to be cleaned or repaired, the bolts 20 can be loosened in sequence and the end cover 19 can be removed to facilitate subsequent maintenance.

[0043] like Figure 7 As shown, the box body 1 and the inner wall of the end cover 19 are respectively fixedly connected with an anti-collision pad 21. The anti-collision pad 21 is made of rubber, or other materials such as acrylic, and is used to buffer the impact force of the ball 6 to ensure the box body 1.

[0044] like Figure 4 As shown, the first electromagnetic block 8 and the second electromagnetic block 10 are distributed in a circular array with the central axis of the box body 1 as the center.

[0045] Specifically, the first electromagnetic block 8 and the second electromagnetic block 10 are composed of an energized solenoid and an iron core. When current is passed through the solenoid, according to Ampere's law, a magnetic field is generated around the current, and the direction of the magnetic field is determined by the direction of the current. The iron core is magnetized in the magnetic field, which greatly enhances the magnetic field strength. In this way, the electromagnet can generate a relatively strong controllable magnetic field. Ferromagnetic materials will be magnetized in the magnetic field and become a magnet. According to the interaction law between magnetic poles, opposite poles attract each other, and like poles repel each other. When the magnetic field generated by the electromagnet acts on the metal ball 6, the metal ball 6 will be affected by the magnetic field force. By controlling the on / off, size and direction of the current in the electromagnet, the presence, strength and direction of the magnetic field can be controlled, thereby precisely controlling the movement of the metal ball 6, including moving, stopping and changing the direction of movement.

[0046] Therefore, when the lifting plate 5 lifts the ball 6, the first electromagnetic block 8 and the second electromagnetic block 10 are energized to adsorb the ball 6 to the inner wall of the box 1. During this process, the ball 6 collides with the silkworm feed additive on the path and breaks into pieces.

[0047] Example 2:

[0048] A method for using a device for breaking up lumps of silkworm feed additives, the method comprising the following steps:

[0049] S1: First, connect the feed pipe 2 to the external hopper, and then control the feed amount of the additive through the control valve 4 so that an appropriate amount of additive is discharged into the interior of the box 1;

[0050] S2: The motor 12 is then started, which drives the crankshaft 13 to rotate. The height displacement difference generated by the rotation of the crankshaft 13 is used to drive the lifting plate 5 up and down through the connecting rod 15, so that the lifting plate 5 drives the balls 6 and the additive to vibrate up and down inside the box 1. During the shaking process, the balls 6 collide with the additive to cause initial breakage.

[0051] S3: Then, the first electromagnetic block 8 and the second electromagnetic block 10 are energized to generate a strong magnet. The first electromagnetic block 8 and the second electromagnetic block 10 are energized in an interlaced manner. In a single energization, only one of the two adjacent first electromagnetic blocks 8 or second electromagnetic blocks 10 is energized to generate a strong magnet.

[0052] S4: When the first electromagnetic block 8 or the second electromagnetic block 10 is energized, the strong magnetism generated quickly attracts the ball 6 to the inner wall of the box 1. As the ball 6 moves toward the inner wall of the box 1, it collides with the additive quickly on its way to break the additive up again. This step is repeated to complete the breaking of the agglomerated additive.

[0053] S5: After the additive is crushed, the control valve 4 is rotated to connect the box 1 with the discharge pipe 3, and the additive is extracted by the external negative pressure to complete the discharge.
