Description

Technical Field

[0001] The present invention relates to the technical field of feed production, and specifically to a liquid spraying system and method for mixing feed crushing raw materials. Background Technique

[0002] During the feed production process, the raw materials are mixed and crushed by the rotation of the main shaft. In the initial stage of raw material crushing, liquid spraying is required to suppress dust, so as to reduce the risk of dust explosion and improve the working environment; while in the later stage of crushing (after the raw materials reach the target particle size), it is necessary to spray additives such as molasses to improve the palatability and nutritional value of the feed. The traditional liquid spraying system usually adopts a multi-nozzle independent design, that is, multiple nozzles are arranged inside the cylinder body, which are respectively used for dust suppression and molasses spraying. However, this design has the following problems:

[0003] Spatial layout conflict: Due to the limited internal space of the crushing / mixing cylinder body, the installation of multiple nozzles is likely to cause overlapping or incomplete coverage of the spraying angles, affecting the uniformity of dust suppression and additive distribution.

[0004] High system complexity: Each nozzle needs to be equipped with an independent liquid tank, conveying pipeline and control valve group, resulting in a significant increase in equipment cost (about 30% - 50%), and it is difficult to maintain and repair in the later stage.

[0054] Please refer to Figures 1 - 18 , the present invention provides a technical solution: a liquid spraying system for mixing feed crushing raw materials, including a cylinder body 1, a feeding port at the bottom of the cylinder body 1 (the feeding port is a conventional setting well-known to those skilled in the art and will not be elaborated), a main shaft 2 arranged inside the cylinder body 1 (crushing blades are arranged outside the main shaft 2, and the raw materials are crushed by the rotation of the main shaft 2. The crushing blades can be various in the prior art and can be selected according to actual production, which belongs to the common knowledge of those skilled in the art and will not be elaborated here and is not shown in the attached drawings), a liquid supply pipeline 3 fixedly arranged inside the cylinder body 1, and a motor 36 fixedly connected to the cylinder body 1. The output shaft of the motor 36 is fixedly connected to the top end of the main shaft 2 and is installed on the cover body 37 on the cylinder body 1. A plurality of spraying assemblies are arranged below the liquid supply pipeline 3. Each spraying assembly includes a connecting block 4, a first flow channel 5, a second flow channel 6, a first liquid flow pipe 7, a second liquid flow pipe 8, a switching cylinder 9, a through hole 10, a sprayer head 11 and a driving assembly. The connecting block 4 is arranged below the liquid supply pipeline 3. The first flow channel 5 is opened inside the connecting block 4. The second flow channel 6 is opened inside the connecting block 4. The first liquid flow pipe 7 is arranged between the liquid supply pipeline 3 and the first flow channel 5. The second liquid flow pipe 8 is arranged between the liquid supply pipeline 3 and the second flow channel 6. The liquid supply pipeline 3 is used to provide different spraying solutions for the first liquid flow pipe 7 and the second liquid flow pipe 8. The switching cylinder 9 is rotatably connected to the connecting block 4 and is hollow inside. The through hole 10 is opened on the switching cylinder 9. The sprayer head 11 is fixedly connected to the switching cylinder 9. The driving assembly is configured to drive the switching cylinder 9 to rotate around its own center point, so that the through hole 10 is selectively communicated with the first flow channel 5 or the second flow channel 6.

[0055] Such as Figures 1 - 7 ,Figure 9 , Figures 11 - 12 As shown: the liquid supply pipeline 3 is used to provide water and molasses to the liquid flow pipe 1 7 and the liquid flow pipe 2 8 respectively, and the liquid spraying operation is evenly performed through the nozzles 11 distributed at equal distances inside the cylinder 1;

[0056] In the initial stage of crushing, the main shaft 2 rotates rapidly to crush, and the nozzle 11 is upward. Figure 3 , Figures 5 - 7 In the upward tilted state shown, the elevation angle of the nozzle 11 can be between 45° and 60°. An upward airflow is generated during the rotation of the main shaft 2. The dust generated during the raw material crushing process diffuses to the top of the cylinder 1 along the upward airflow. The atomized water droplets sprayed upward collide with the rising dust in the opposite direction when falling, and the dust is captured by inertial impact and wetting, thereby suppressing dust and wetting the raw materials to reduce the subsequent explosion risk. In addition, the raw material particle size is large in the initial stage of crushing, and the water mist sprayed upward can evenly cover the particle surface during free fall, avoiding local over-wetting that affects the moisture ratio of the feed particles themselves.

[0057] In the late stage of crushing, when the target particle size is reached, the main shaft 2 rotates slowly (high-speed rotation after reaching the target particle size is prone to over-crushing), and the nozzle 11 is downward:

[0058] In the later stage of crushing, the angle of the nozzle 11 is as follows Figure 9 and Figure 15 As shown, the nozzle 11 can be tilted downward at an angle of 15°. At this time, the rotation speed of the main shaft 2 is reduced, the airflow is weakened, and the dust is reduced. The material is in a semi-fluidized state and is mainly at the bottom of the cylinder 1. In the later stage, the specific surface area of the raw material is large. At this time, the nozzle 11 can directly target the raw material layer to ensure accurate adsorption of molasses, and spray downward to shorten the flight path of the droplets.

[0059] The angle adjustment of the nozzle 11 in the early and late stages of crushing is controlled by the driving component, and its working state switching is based on the real-time speed monitoring of the main shaft 2 by the real-time monitoring system of the shaft speed (the real-time monitoring system technology of the shaft speed is an existing technology. The real-time monitoring system of the shaft speed realizes real-time tracking of the dynamic speed through sensors, signal processing modules and data analysis platforms. It is widely used in industrial processing, ship power, mechanical transmission and other fields. The installation is a conventional setting, and its specific setting is not repeated); when the speed of the main shaft 2 reaches the high-speed range of 1000-1200rpm in the early stage of crushing, the system triggers the following coordinated actions: the switching cylinder 9 tilts up to adjust the spray angle of the nozzle 11, so that the through hole 10 accurately docks with the flow channel 15, and the flow channel 2 6 is closed synchronously to form a closed flow channel. At this time, the liquid supply pipeline 3 pumps water into the flow channel 15 through the liquid flow pipe 17. After the water enters the cavity of the switching cylinder 9 through the through hole 10, the nozzle 11 finally implements efficient dust suppression operation; this dynamic adjustment mechanism realizes the adaptive matching of the crushing working condition and the dust suppression intensity, and effectively improves the dust control accuracy.

[0060] After the raw materials are crushed to the target particle size, the rotation speed of the main shaft 2 is reduced to 500 - 600 rpm. After the shaft rotation speed real-time monitoring system obtains the data, the driving assembly controls the switching cylinder 9 to rotate downward around the rotating shaft on the connecting block 4 from Figure 5 the state shown to Figure 9 the state shown. During the rotation of the switching cylinder 9, the through hole 10 will rotate towards the flow channel two 6. When the through hole 10 crosses the flow channel one 5, the side wall of the switching cylinder 9 remains in contact with the flow channel one 5 to seal the flow channel one 5, thereby blocking the flow of water;

[0061] After the through hole 10 rotates to communicate with the flow channel two 6, the supply pipeline 3 sprays the molasses atomized through the liquid flow pipe two 8, the flow channel two 6, the through hole 10, and the inner cavity of the switching cylinder 9 through the nozzle 11, thus completing the switching of the spraying solution in the initial stage and the later stage of crushing;

[0062] The present invention automatically realizes the switching of the nozzle 11 and different supply pipelines 3 according to the rotation speed of the main shaft 2, meets the requirements of solution spraying in the initial stage and the later stage of crushing, has the advantages of reducing space occupation, reducing costs, and optimizing the equipment structure. The nozzle 11 does not need to be equipped with an independent supply pipeline 3 and supporting equipment, reducing the difficulty of equipment maintenance. Moreover, the nozzle 11 is configured with two supply pipelines 3 and can be automatically switched according to the scenario. When switching to the dust suppression process, the molasses remaining inside the nozzle 11 during the molasses spraying process can be automatically cleaned under the action of water flow, avoiding blockage of the nozzle 11.

[0063] A first filter screen 12 is arranged inside the through hole 10.

[0064] As Figures 6 - 8 、 Figures 10 - 11 shown:

[0065] During the long-term working process, the nozzle 11 needs to be switched up and down multiple times. When the nozzle 11 is in the dust suppression working position, the switching cylinder 9 seals the flow channel two 6. Although the molasses usually remains at a constant temperature (40°) inside the liquid flow pipe two 8, the side wall of the switching cylinder 9 inside the flow channel two 6 is still likely to cause the molasses to form an adhesion layer as Figure 8 shown (the adhesion layer is represented by A1 in the figure). After it is formed, when the nozzle 11 rotates from the upward tilt to the downward tilt, with the rotation of the switching cylinder 9, the inner wall of the flow channel two 6 will push it, causing it to turn into a lump as Figure 10 shown (the lump is represented by A2 in the figure). The first filter screen 12 located inside the through hole 10 can block the through hole 10, preventing the lump from entering the inner cavity of the switching cylinder 9, thereby avoiding the lump from blocking the nozzle 11;

[0066] Through the blockage of the lumps by the first filter screen 12, when spraying molasses, the molasses liquid flows from the second flow channel 6 through the first filter screen 12 into the inner cavity of the switching cylinder 9, which will impact the lumps, causing the lumps to be on the first filter screen 12. During the impact process, the lumps will melt, and the melted lumps will pass through the first filter screen 12 and enter the inner cavity of the switching cylinder 9 and then be discharged through the nozzle 11;

[0067] If the lumps cannot melt, when the nozzle 11 rotates again, the through hole 10 rotates from being connected to the second flow channel 6 to being connected to the first flow channel 5. At this time, the first filter screen 12 will drive the lumps to rotate from the inside of the second flow channel 6 to the inside of the first flow channel 5 under the bonding action of the lumps. Moreover, the water temperature (50° - 60°) inside the first flow channel 5 is higher than the temperature when the molasses is at a constant temperature. When the lumps rotate into the inside of the first flow channel 5, the high-temperature hot water passes through the first filter screen 12 and the through hole 10 and enters the inner cavity of the switching cylinder 9, which will melt the lumps (as Figure 12 shown), so that the lumps will not block the first filter screen 12 due to inability to melt, resulting in difficulties in subsequent liquid flow.

[0068] A second filter screen 13 is arranged inside the second flow channel 6. After the first filter screen 12 rotates with the switching cylinder 9 to the maximum extent, it will be directly below the second filter screen 13.

[0069] The top end of the second filter screen 13 is fixedly connected with a pressure rod 20. The top end of the pressure rod 20 is located outside the switching cylinder 9. The pressure rod 20 is slidably connected with the switching cylinder 9. A first spring 40 is fixedly connected between the pressure rod 20 and the connecting block 4. When the pressure rod 20 slides along the switching cylinder 9, it can drive the second filter screen 13 to slide inside the second flow channel 6. The bottom of the second filter screen 13 is fixedly connected with a top rod 19. After the driving assembly drives the switching cylinder 9 to rotate downward to the maximum extent, it will push the pressure rod 20 to slide along the switching cylinder 9.

[0070] As Figures 7 - 11 shown:

[0071] After the through hole 10 is switched from being connected to the first flow channel 5 to being connected to the second flow channel 6, the first filter screen 12 will be below the second filter screen 13. At this time, the second filter screen 13 will block the upper part of the lumps, thus preventing the lumps from possibly flowing backward and entering the inside of the second flow channel 6;

[0072] When the through hole 10 rotates to be connected to the second flow channel 6 and the nozzle 11 rotates upward to the maximum extent and then stops, and the driving assembly will press down the pressure rod 20, causing the pressure rod 20 to slide down along the connecting block 4 and compress the first spring 40. When the pressure rod 20 slides down along the connecting block 4, it will drive the second filter screen 13 to slide down inside the second flow channel 6. When the second filter screen 13 slides down, the bottom end of the top rod 19 will push the lumps adhered to the inner wall of the second flow channel 6, so that the lumps can be pushed to adhere to the first filter screen 12. When the top rod 19 pushes the lumps, the scouring of the lumps during the molasses flow process can facilitate the movement of the lumps to fit with the first filter screen 12, and then be easily driven into the inside of the first flow channel 5.

[0073] A rotating rod 14 is rotatably connected inside the switching cylinder 9 , and a plurality of cleaning rods 15 are fixedly connected to the rotating rod 14 . The ends of the cleaning rods 15 are in contact with the inner wall of the switching cylinder 9 .

[0074] As a further solution of the present invention, the filter screen 12 is slidably connected to the switching cylinder 9, the inner wall of the switching cylinder 9 is rotatably connected to a push rod 16, the bottom end of the push rod 16 extends obliquely toward the inside of the switching cylinder 9, the rotating sleeve of the push rod 16 is provided with a torsion spring 17, the bottom end of the push rod 16 is rotatably connected to a support rod 18, and the bottom end of the support rod 18 is rotatably connected to the filter screen 12;

[0075] When the cleaning rod 15 rotates to contact the push rod 16, it pushes the push rod 16 to rotate around the rotation axis and pushes the filter screen 12 to slide on the inner wall of the switching cylinder 9 through the support rod 18.

[0076] like Figure 6 , Figures 12 - 14 As shown:

[0077] The rotating rod 14 is driven by a separate driving source, which may be a motor or other source capable of driving the rotating rod 14 to rotate. When the rotating rod 14 rotates, it drives the cleaning rod 15 to rotate in the inner cavity of the switching cylinder 9. Through the contact between the end of the cleaning rod 15 and the inner wall of the switching cylinder 9, the inner wall of the switching cylinder 9 can be scraped and cleaned to avoid impurities accumulated on the inner wall of the switching cylinder 9 and affecting the normal use of the nozzle 11.

[0078] After the cleaning rod 15 rotates to contact the inclined push rod 16, it will push the push rod 16, so that the push rod 16 rotates around the rotation axis and presses down the support rod 18. When the support rod 18 is pressed down, it will push the filter 12 to slide along the inside of the switching cylinder 9 relative to the inside of the chute opened by the filter 12. When the cleaning rod 15 passes over the push rod 16, the torsion spring 17 will elastically drive the push rod 16 to reset, so that the filter 12 forms a swing inside the chute;

[0079] The swing formed by the filter screen 12 can cause the agglomerates adhered to the filter screen 12 to be moved inside the flow channel 5, thereby facilitating the rapid dissolution of the agglomerates.

[0080] The driving assembly includes a telescopic member 21, which is any one of an electric cylinder and an electric push rod that can be wirelessly controlled. The telescopic member 21 is fixedly connected to the side wall of the connecting block 4, and the telescopic member 21 is fixedly connected to a resisting rod 22, and the resisting rod 22 is fixedly connected to a driving rod 23. The bottom of the driving rod 23 is wedge-shaped and is located above the bottom end of the pressure rod 20. The driving rod 23 is slidably connected to a pull rod 24, and a second spring 41 is fixedly connected between the pull rod 24 and the driving rod 23. The pull rod 24 is slidably connected to the switching cylinder 9, and the pull rod 24 is rotatably connected to a connecting member 25. The bottom end of the connecting member 25 is rotatably connected to a round rod 26, and the round rod 26 is fixedly connected to the side wall of the switching cylinder 9.

[0081] like Figure 5 , Figures 15 - 18 As shown:

[0082] Initial stage of breaking:

[0083] The main shaft 2 rotates at a high speed, the nozzle 11 is facing upward to the maximum extent, the telescopic member 21 is in a state of being extended to the maximum length, and at this time the resistance rod 22 is in contact with the main shaft 2 and resists the main shaft 2. The resistance of the resistance rod 22 causes the main shaft 2 to rotate by static friction and drives the connecting block 4, the flow channel 1 5, and the flow channel 2 6 to rotate synchronously inside the cylinder 1. When the nozzle 11 rotates synchronously with the main shaft 2, the droplet spraying direction matches the dust throwing trajectory, and the collision probability is increased through the relative static effect. When the nozzle 11 rotates, an annular spray curtain is formed, which is conducive to covering the top of the raw material;

[0084] Late stage of crushing:

[0085] When the speed of the main shaft 2 is reduced, the real-time monitoring system of the rear axle speed controls the telescopic member 21 to shorten. At this time, the telescopic member 21 will drive the resisting rod 22 to break away from the contact with the main shaft 2. At this time, the connecting block 4 will be stationary. When the telescopic member 21 shortens, the second spring 41 pushes the pull rod 24 to slide along the connecting block 4. The pull rod 24 pushes the switching cylinder 9 and the nozzle 11 to rotate downward to the maximum extent through the connecting member 25. At this time, the nozzle 11, the connecting member 25, and the pull rod 24 are in the following state. Figure 15 The stationary state shown in FIG. 1 , and at this time the driving rod 23 and the pressure rod 20 are in a Figure 16 As shown, at this time, the wedge-shaped end of the driving rod 23 is about to contact the pressure rod 20;

[0086] When the nozzle 11 rotates downward to the maximum extent, the telescopic member 21 can be shortened by a small distance. The telescopic member 21 continues to shorten so that the driving rod 23 slides along the pull rod 24. At this time, the second spring 41 will be compressed, and the bottom end of the wedge-shaped driving rod 23 will contact the pressure rod 20 and press the pressure rod 20 downward, so that the filter screen 13 can be lowered. After the telescopic member 21 is shortened to the maximum extent, the driving rod 23 will pass over the pressure rod 20.

[0087] When the nozzle 11 switches position again, the telescopic member 21 can be extended to the maximum extent;

[0088] When the connecting block 4 rotates with the main shaft 2, centrifugal force will be generated, and the centrifugal force may cause the droplets to be thrown outward, causing them to leave the target area. The solution to this problem can be to compensate for the reverse angle of the nozzle 11 (tilt the nozzle 11 inward by 10 to 15 degrees to offset the droplets thrown outward due to the centrifugal force), increase the atomization pressure, and shorten the rotation radius of the nozzle 11 to overcome it, so as not to affect normal spraying.

[0089] The liquid supply pipeline 3 includes a first annular pipe 27 and a second annular pipe 28. The first liquid flow pipe 7 and the second liquid flow pipe 8 are respectively fixedly connected to the first annular pipe 27 and the second annular pipe 28.
