Description

Technical Field

[0001] This invention relates to the field of feed moisture determination technology, and in particular to a moisture determination device and method for compound premixed feed production. Background Technology

[0002] Compound premixed feed refers to a mixture of one or more additive raw materials (or monomers) and carriers or diluents, also known as additive premix or premix. Its purpose is to facilitate the uniform dispersion of trace amounts of raw materials in a large amount of compound feed. Premixed feed cannot be fed directly to animals. Premixed feed can be regarded as the core of compound feed because the trace active components it contains are often the determining factors of the feeding effect of compound feed. Among them, the most important process in compound premixed feed is moisture determination, which often requires the assistance of moisture measuring equipment.

[0003] Referring to prior art document CN213148861U, this utility model discloses a moisture measuring device for compound premixed feed production. The device includes a moisture measuring apparatus, with a mounting box fixedly installed at its bottom. A threaded hole is provided at the left end of the mounting box, through which a threaded rod is threadedly connected. One end of the threaded rod extends into the mounting box, and the other end extends outwards. A first bevel gear is fixedly installed at the right end of the threaded rod. A rotating rod is rotatably connected between the upper and lower sides of the inner cavity of the mounting box. A second bevel gear, meshing with the first bevel gear, is fixedly installed on the outside of the rotating rod. A first pulley, located above the second bevel gear, is fixedly installed on the outside of the rotating rod. A second pulley, located to the right of the rotating rod, is rotatably connected to the top of the inner cavity of the mounting box. The first and second pulleys are rotatably connected externally via a transmission belt. This moisture measuring device for compound premixed feed production has the advantage of stable placement.

[0004] While the reference document has the advantage of stable placement, it lacks a feed pulverizing mechanism. When testing feed moisture content, it needs to be pulverized into uniform particles. If the feed is not pulverized, larger or clumped particles will not evaporate their internal moisture completely during drying or heating, resulting in lower measured values. Furthermore, existing testing devices lack a turning mechanism for the feed during drying. If the feed is not turned during drying, a thermal gradient may form within the feed layer under static conditions, causing the outer layer to dry completely while the inner layer remains moist, resulting in uneven drying and affecting testing accuracy. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing drying equipment that lack crushing and turning mechanisms, and to propose a moisture determination device and method for compound premixed feed production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] The turning mechanism is located in the drying chamber and is linked with the crushing mechanism to turn the feed over during the drying process.

[0010] The air blowing mechanism is installed inside the turning mechanism to blow hot air onto the feed during the feed drying process.

[0011] Preferably, a dual-axis motor is fixedly connected inside the drying chamber. A transmission rod and a rotating rod are respectively installed on the upper and lower output ends of the dual-axis motor. The transmission rod extends through the interior of the grinding tank. A feeding protrusion is fixedly connected to the bottom of the grinding tank. The transmission rod rotates through the feeding protrusion. Multiple grinding blades are fixedly connected to the outer wall of the transmission rod. An adsorption magnet is fixedly connected to the outer wall of the bottom grinding blades. Storage cavities are opened on both sides of the bottom of the grinding tank. The bottom of the storage cavity is concave. A conveying pipe is connected to the bottom of the storage cavity.

[0012] Preferably, a screen is slidably connected to the inner wall of the storage chamber, and a screening magnetic block is fixedly connected to the outer wall of the screen. The magnetic poles of the screening magnetic block are opposite to those of the adsorption magnet. Multiple mounting parts are fixedly connected to the bottom of the main body of the equipment. The multiple mounting parts are arranged in an inverted "L" shape. A return spring is fixedly connected to the lower outer wall of the mounting part. The end of the return spring away from the mounting part is fixedly connected to the outer wall of the screen.

[0013] Preferably, the overturning mechanism includes a drying basket disposed in the drying chamber, the middle part of the drying basket being rotatably connected to a rotating rod, a plurality of vibrating magnets being fixedly connected to the bottom of the drying basket, connecting rods being fixedly connected to both sides of the drying basket, the connecting rods being provided with square protrusions, sliding rails being fixedly connected to both sides of the inner sidewall of the drying chamber, a vibration spring being provided on the inner sidewall of the sliding rail, the front end of the connecting rod being slidably disposed inside the sliding rail, and the lower end of the vibration spring contacting the upper end of the connecting rod.

[0014] Preferably, a spoiler is fixedly connected to the bottom of the rotating rod, and side plates are fixedly connected to both sides of the spoiler. A trigger magnet is fixedly connected to the upper outer wall of the spoiler, and the magnetic poles of the trigger magnet and the vibrating magnet are the same.

[0015] Preferably, the blowing mechanism includes multiple spray nozzles fixedly connected to the outer wall of the drying basket, and push rods are slidably connected to the inner walls of the multiple spray nozzles.

[0016] Preferably, a top plate is fixedly connected to the bottom of the dual-axis motor, the top plate is rotatably connected to the rotating rod, and the lower outer wall of the top plate is connected to the top of the push rod.

[0017] Preferably, the inner wall of the spray nozzle is connected to a jet pipe, and the front end of the jet pipe is provided with a barrier net.

[0018] Preferably, the top of the pulverizing tank is provided with a pluggable feeding port, which extends into the interior of the pulverizing tank.

[0019] A method for using a moisture determination device for compound premixed feed production, characterized by the following steps:

[0020] S1: During use, the operator can put the feed that requires moisture testing into the grinding tank through the feeding port. After the feed is put into the grinding tank, the operator can turn on the dual-shaft motor to drive the transmission rod and the rotating rod to rotate synchronously. When the transmission rod rotates, it will grind the feed in the main body of the equipment through the grinding blades.

[0021] S2: When a large amount of feed accumulates at the bottom of the storage chamber, the operator can open the solenoid valve in the conveying pipe to allow the screened feed to enter the drying basket through the conveying pipe. When the feed enters the drying basket, the rotating rod will also drive the baffle and side plate to rotate, disturbing the hot air in the drying chamber, enhancing the heat exchange between the feed and the air, and making the heat more evenly transferred to the feed, thus improving the drying efficiency.

[0022] S3: When the drying basket vibrates up and down, it will drive the spray nozzle to vibrate up and down as well. At this time, the push rod will move up and down inside the spray nozzle. When the rotating rod moves up and down inside the spray nozzle, it will spray air into the drying basket through the air jet pipe. The air jet helps to break up the particles. Finally, the drying basket will weigh the feed through the built-in weighing module. After the above operations, when the feed is dried, the weighing module will re-weigh the dried feed to obtain the difference between the two values, and thus calculate the moisture content.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. By setting up a pulverizing mechanism that can crush and screen feed, the operator can put the feed to be tested into the pulverizing tank during use. The operator can then turn on the dual-shaft motor, which drives the pulverizing blades to rotate through the transmission rod, pulverizing the feed in the pulverizing tank. While the pulverizing blades are rotating and crushing the feed, the magnetic force can also cause the screen to vibrate up and down in the storage chamber, screening the pulverized feed and ensuring that the feed particles that are dried later are of uniform size, avoiding uneven particle size and insufficient drying.

[0025] 2. The drying basket, designed to turn the feed over through vertical vibration, allows the feed in the grinding tank to be evenly pulverized and fall into the drying basket. At this time, a baffle plate and side plate driven by a dual-shaft motor rotate within the drying chamber, agitating the hot air and enhancing heat exchange between the feed and the air. This ensures more even heat transfer to the feed, improving drying efficiency. Simultaneously, the baffle plate uses magnetic force to vibrate the drying basket vertically, turning the feed over and preventing thermal gradients, ensuring uniform heating. The air-blowing mechanism, activated by the vibration, sprays air through the nozzles to break up particles, reducing particle sticking caused by moisture, maintaining fertilizer flowability and storage properties, and improving the accuracy and efficiency of moisture detection.

The end of return spring 308 away from mounting component 307 is fixedly connected to the outer wall of screen 304. The overturning mechanism is set in the drying chamber 2 and is linked with the crushing mechanism. During drying, the feed is overturned. The overturning mechanism includes a drying basket 205 set in the drying chamber 2. The middle part of the drying basket 205 is rotatably connected to the rotating rod 204.

[0043] It should be noted that the drying basket 205 is equipped with a flip hinge. After the moisture content of the feed in the drying basket 205 has been tested, the operator can open the front material handling door of the main body 1 of the equipment, flip the drying basket 205 open, and take out the feed sample in the drying basket 205.

[0044] Referring to 4-10, multiple vibrating magnets 209 are fixedly connected to the bottom of the drying basket 205.

[0046] It should be noted that a switch valve is installed inside the conveying pipe 202, so hot air will not be conducted to the crushing tank 3 through the conveying pipe 202.

[0047] A method for using the moisture measuring device for compound premixed feed production according to any one of claims 1-9, the method comprising the following steps:

[0048] S1: In use, the operator can put the feed that requires moisture testing into the grinding tank 3 through the feeding port 301. After the feed is put into the grinding tank 3, the operator can turn on the dual-shaft motor 201 to drive the transmission rod 303 and the rotating rod 204 to rotate synchronously. When the transmission rod 303 rotates, it will grind the feed in the main body 1 of the equipment through the grinding blades 302.

[0049] S2: When a large amount of feed accumulates at the bottom of the storage chamber 306, the operator can open the solenoid valve in the conveying pipe 202 to allow the screened feed to enter the drying basket 205 through the conveying pipe 202. When the feed enters the drying basket 205, the rotating rod 204 will also drive the baffle 206 and the side plate 208 to rotate, disturbing the hot air in the drying chamber 2, enhancing the heat exchange between the feed and the air, and making the heat more evenly transferred to the feed, thus improving the drying efficiency.

[0050] S3: When the drying basket 205 vibrates up and down, it will drive the spray nozzle 214 to vibrate up and down together. At this time, the push rod 203 will push up and down inside the spray nozzle 214. When the rotating rod 204 pushes up and down inside the spray nozzle 214, it will spray air into the drying basket 205 through the air jet pipe 215. The air jet can help break up the particles. Finally, the drying basket 205 will weigh the feed through the built-in weighing module. After the above operations, when the feed is dried, the weighing module will re-weigh the dried feed to obtain the difference between the two values, and thus calculate the moisture content.

[0051] The working principle of the moisture determination equipment and method for compound premixed feed production in this invention is as follows:

[0052] In use, the operator can place the feed requiring moisture testing into the grinding tank 3 through the feeding port 301. After the feed is placed into the grinding tank 3, the operator can turn on the dual-shaft motor 201, causing it to drive the transmission rod 303 and the rotating rod 204 to rotate synchronously. When the transmission rod 303 rotates, it will crush the feed in the main body 1 through the crushing blades 302. The crushed feed will fall onto the screen 304 at the bottom of the main body 1 through the feeding protrusion 309. When the bottom crushing blades 302 rotate and crush the feed, they will also drive the adsorption magnets 310 below them to rotate. When the adsorption magnets 310 rotate to be directly above the screening magnetic block 305, the two... As the distance between them decreases, the magnetic poles of the adsorption magnet 310 and the screening magnetic block 305 are opposite, and they will attract each other. At this time, the screen 304 will move upward in the storage cavity 306. Conversely, when the crushing blade 302 at the bottom drives the adsorption magnet 310 to rotate away from the screening magnetic block 305, the distance between them increases, and the magnetic attraction disappears. At this time, under the elastic force of the return spring 308, the screen 304 will move downward in the storage cavity 306 back to its original position. Since the adsorption magnet 310 rotates continuously with the crushing blade 302 at the bottom, under the action of intermittent magnetic attraction and the elastic force of the return spring 308, the screen 304 will vibrate up and down repeatedly in the storage cavity 306.

[0053] When the screen 304 vibrates back and forth in the storage chamber 306, it can screen the feed crushed in the grinding tank 3. The feed that meets the requirements will fall into the concave bottom of the storage chamber 306, while larger particles that do not meet the requirements will remain in the grinding tank 3 and continue to be crushed. When a large amount of feed accumulates at the bottom of the storage chamber 306, the operator can open the solenoid valve in the conveying pipe 202 to allow the screened feed to pass through the conveying pipe 202 into the drying basket 205. As the feed enters the drying basket 205, the rotating rod 204 will also drive the baffle 206 and the side plate 208 to rotate, disturbing the hot air in the drying chamber 2, enhancing the heat exchange between the feed and the air, so that the heat is transferred to the feed more evenly, improving the drying efficiency. While the baffle 206 rotates and disturbs the air, it will also drive the trigger magnet 207 to rotate. When the trigger magnet 207 rotates to the direct below the vibrating magnet 209, the drying basket 205 will be lifted up by the repulsive magnetic force.

[0054] When the trigger magnet 207 rotates with the baffle 206 to a position away from the vibrating magnet 209, the distance between them increases, and the magnetic force disappears. Under the elastic force of the vibration spring 211, the drying basket 205 returns to its original position. The combined action of the magnetic force and the elastic force of the vibration spring 211 causes the drying basket 205 to vibrate up and down within the sliding rail 210. This vibration overturns the feed within the drying basket 205, preventing the formation of a heat gradient and ensuring uniform heating. The vibration of the drying basket 205 also causes the spray nozzle 214 to vibrate up and down simultaneously. At this time, the push rod 203... The rotating rod 204 moves up and down within the spray nozzle 214. When the rotating rod 204 moves up and down within the spray nozzle 214, it sprays air into the drying basket 205 through the air jet pipe 215. The air jet helps to break up the particles, reduce particle sticking caused by moisture, maintain the fluidity and storage characteristics of the fertilizer, and improve the accuracy and efficiency of moisture detection. When the feed enters the drying basket 205, the drying basket 205 weighs the feed through its built-in weighing module. After the above operation, when the feed is dried, the weighing module will re-weigh the dried feed to obtain the difference between the two values, thereby calculating the moisture content (this is existing technology and will not be elaborated further).

[0055] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0056] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

When the feed comes into the drying basket (205), the rotating rod (204) will also drive the baffle (206) and the side plate (208) to rotate, disturbing the hot air in the drying chamber (2), enhancing the heat exchange between the feed and the air, so that the heat is transferred to the feed more evenly and the drying efficiency is improved. S3: When the drying basket (205) vibrates up and down, it will drive the spray nozzle (214) to vibrate up and down together. At this time, the push rod (203) will push up and down inside the spray nozzle (214). When the rotating rod (204) pushes up and down inside the spray nozzle (214), it will spray air into the drying basket (205) through the air jet pipe (215). The air jet can help break up the particles. Finally, the drying basket (205) will weigh the feed through the built-in weighing module. After the above operation, when the feed is dried, the weighing module will re-weigh the dried feed to obtain the difference between the two values ​​and calculate the moisture content.
