Description

Technical Field

[0001] This invention relates to the field of spraying equipment technology, specifically a spraying system. Background Technology

[0002] Post-oil coating equipment for pelleted feed is used to spray oil onto the surface of pelleted feed, primarily to improve its quality and nutritional value. With the development of animal husbandry, pelleting has become a trend because it can improve feed nutrient absorption and animal production performance. However, pelleted feed often needs to be coated with oil during production to improve its palatability and nutritional value. Therefore, post-oil coating equipment for pelleted feed has emerged as an important feed processing device. Post-oil coating equipment for pelleted feed typically includes a spraying device and a conveying device. The spraying device applies oil to the surface of the pellets, while the conveying device transports the pellets into the spraying device. The technical challenge of this equipment lies in accurately controlling the spraying amount and position to ensure a uniform oil coating on the pellet surface. To address this issue, some advanced spraying devices employ precise metering systems and spray heads to ensure the accuracy and uniformity of the spraying amount. Previous generation of post-oil coating equipment used a mains scale to measure the material. The mains scale's metering principle involves the impact of upstream material on the mains scale plate; the system converts the impact force into a weighing mass through calculation.

[0028] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] The present invention provides the following embodiments.

[0030] Example 1

[0031] This invention provides a spraying system, such as... Figure 1 As shown, a spraying system includes: a spraying bracket 2, a base plate 1 on which the spraying bracket 2 is fixedly installed, a metering mechanism is fixedly installed on the spraying bracket 2, a spraying mechanism 5 is provided below the bottom of the metering mechanism, and a mixing and conveying device 3 is provided below the spraying mechanism 5.

[0032] The metering mechanism includes: a dual metering hopper 4, the dual metering hopper 4 is fixedly installed on the top of the spraying bracket 2, a weighing sensor 6 is fixedly installed between the dual metering hopper 4 and the spraying bracket 2, and an electric valve 7 is fixedly connected to the bottom of the dual metering hopper 4, and the electric valve 7 is fixedly connected to the material inlet pipe 8.

[0033] The top of the spraying bracket 2 is fixedly installed with an electric tee 9, which is fixedly connected to the top inlet of the double metering hopper 4.

[0034] The working principle and beneficial effects of the above technical solution are as follows: When the spraying system is working, the pelleted feed is screened and enters the electric tee 9 through the finished product chute, then enters the dual metering bins, and enters the mixing and conveying device 3 after passing through the electric gate and the feed inlet pipe 8. The two metering bins alternately feed and discharge, continuously conveying the feed to the mixing and conveying device 3 to meet the needs of continuous production. The first weighing sensor 6 records the weight change data of the dual metering bins 4. After PLC calculation, the system obtains the weight reduction of the metering bins. The second weighing sensor 11 in the weighing oil tank 10 records the weight change data. The adjustable frequency oil pump controls the frequency of the spray pump 13 according to the reduction amount and the formula percentage, so that the oil is evenly sprayed from the spraying mechanism 5 onto the feed at the feed inlet 40 of the mixing box 39. After being sprayed with oil, the feed enters the screw 38 for stirring, achieving the purpose of mixing and conveying to the finished product bin.

[0035] This invention directly weighs the particles using dual metering chambers, eliminating the need for system calculations and thus improving the metering and spraying accuracy of the equipment. Compared to mainstream post-spraying equipment, it has the following advantages.

[0036] 1. Improved weighing accuracy of granular materials, which in turn improved oil spraying accuracy, resulting in uniform and precise oil spraying and stable operation;

[0037] 2. It achieves the goal of continuous batch weighing and feeding, ensuring accurate weighing and high continuous production efficiency;

[0038] 3. It has the advantages of small footprint and convenient maintenance, bringing considerable profits to feed mills.

A one-way valve 18 is installed on pipe 17. Pipe 17 is connected to the extrusion chamber 19. The extrusion chamber 19 is fixedly connected to the inner wall of the filter box 14. The bottom of the extrusion chamber 19 is connected to pipe 20. A piston 21 is slidably connected to the extrusion chamber 19. A push rod 22 is fixedly connected to the left end of the piston 21. A baffle 23 is fixedly connected to the left end of the push rod 22. A spring 24 is sleeved on the outer side of the push rod 22 of the filter box 14. The two ends of the spring 24 are fixedly connected to the baffle 23 and the outer side of the filter box 14, respectively. The baffle 23 is driven by a drive device.

[0041] The filter box 14 is rotatably connected to the bottom center of the rotating vertical tube 26. The top of the rotating vertical tube 26 is rotatably connected to the second pipe 20. The bottom of the rotating vertical tube 26 is fixedly connected to the horizontal tube 27. The horizontal tube 27 is provided with a number of nozzles 28. The rotating vertical tube 26 is driven by the first driving device.

[0042] The drive unit includes: a hybrid motor 30, a belt drive assembly 1, and a cam 25. The hybrid motor 30 is fixedly installed in the middle of the left end of the spraying bracket 2. The output shaft of the hybrid motor 30 is fixedly connected to the vertical shaft 31. The vertical shaft 31 is rotatably connected to the bearing bracket 32. The bearing bracket 32 ​​is fixedly connected to the spraying bracket 2. The vertical shaft 31 is fixedly connected to the cam 25 from the top. The vertical shaft 31 drives the rotating vertical tube 26 to rotate through the belt drive assembly 1.

[0043] The belt drive assembly includes: a pulley 29, which is fixedly connected to the rotating vertical tube 26; a cam 25 that contacts and engages with the left end of the baffle 23; a pulley 34 that is fixedly connected to the middle of the vertical shaft 31; and a pulley 34 that is connected to the pulley 29 via a belt 35.

[0044] The driving device 1 also drives the mixing conveying device 3, which includes: a screw rod 38 rotatably connected to a mixing box 39, a mixing box 39 fixedly connected to a bottom plate 1, a feed inlet 40 at the left end of the mixing box 39, and a discharge outlet 41 at the right end of the mixing box 39.

[0045] The drive unit also includes: a first bevel gear 36 and a second bevel gear 37. The bottom end of the vertical shaft 31 is fixedly connected to the first bevel gear 36, the first bevel gear 36 is meshed with the second bevel gear 37, and the second bevel gear 37 is fixedly connected to the spiral rod 38.

[0046] The working principle of the above technical solution is as follows: When the feed can enter the feed inlet 40 of the mixing box 39, the spraying mechanism 5 starts to work. The spray pump 13 operates to send the grease or spraying liquid into the filter box 14 through the extraction delivery pipe 12. After the grease or spraying liquid passes through the filter screen 15 to remove impurities, it enters the upper cavity of the partition 16. At this time, the mixing motor 30 operates to drive the vertical shaft 31, cam 25, pulley 34 and bevel gear 36 to rotate synchronously. Cam 23 drives the baffle 23, push rod 22 and piston 21 to slide back and forth under the action of spring 24. The material is repeatedly squeezed left and right in the extrusion chamber 19. At this time, the one-way valve 18 opens and the grease or spray liquid flows through the pipe 17, the extrusion chamber 19, the pipe 20, the rotating vertical pipe 26, and the horizontal bar 62, and is finally sprayed out by the nozzle 28. At the same time, the pulley 24 drives the pulley 29, the rotating vertical pipe 26, and the horizontal bar 62 to rotate through the belt 29, which expands the spraying area and spreads it out. The bevel gear 36 meshes and drives the bevel gear 37 and the threaded rod 63 to rotate. The rotation of the threaded rod 63 makes the granules and the grease or spray liquid fully mixed and then flow out through the discharge port 41.

[0047] The beneficial effects of the above technical solution are as follows: the spraying mechanism 5 and the mixing and conveying device 3 enable quantitative control of the spraying amount of grease and spraying liquid, the filter box 14 filters out impurities in the grease and spraying liquid, improves the product quality of granules, and the rotational uniform spraying onto the granules expands the spraying range.

[0048] Example 3

[0049] Based on Example 2, such as Figures 2-4 As shown, the right end of the mixing and conveying device 3 is provided with a spraying and unblocking recovery device 42. The spraying and unblocking recovery device 42 includes: a vibrating box 43. The vibrating box 43 is fixedly installed at the top of the output end of the mixing box 39.

The top of the upper and lower walls of the vibrating box 43 is fixedly connected to the top of the rotating shaft 46, and the left and right ends of the drive mounting frame 44 are rotatably connected to the pulleys 48. The pulleys 48 and 47 are connected by the belt 2 49. The bottom of the shaft of the pulley 48 is fixedly connected to the cylindrical cam 50. The cylindrical cam 50 has a groove 51. The groove 51 is at a different height along the circumference of the cylindrical cam 50. The drive mounting frame 44 is symmetrically fixedly installed with sliding sleeves 52 on the left and right sides. The sliding sleeves 52 vertically penetrate the top wall of the vibrating box 43.

[0050] The sliding sleeve 52 is slidably connected to the L-shaped support rod 53. The upper side of the L-shaped support rod 53 is slidably connected to the groove 51. The bottom of the rotating shaft 46 is fixedly connected to the spur gear 54. The bottom wall of the vibration box 43 is symmetrically connected to the rotating shaft 55. The top of the rotating shaft 55 is fixedly connected to the spur gear 56. The spur gear 54 and the spur gear 56 are meshed. The bottom of the rotating shaft 55 is fixedly connected to the fan blade 57. The lower end of the vibration box 43 is fixedly installed outside the fan blade 57, and the bottom of the fan blade 57 is fixedly installed with the air collecting duct 58. The bottom of the air collecting duct 58 is fixedly installed with the heating net 59.

[0051] L-shaped support rod 1 53 is fixedly connected to L-shaped support rod 2 60 in the middle. Sliding holes 61 are opened on the left and right sides of the vibration box 43. L-shaped support rod 2 60 is slidably connected to the sliding holes 61. The bottom end of L-shaped support rod 2 60 is fixedly connected to a crossbar 62 along the front and rear direction. The front and rear ends of the crossbar 62 are symmetrically connected to threaded rods 63. The four corners of the filter screen 64 are hinged to threaded sleeves 65. The threaded sleeves 65 are threadedly connected to the bottom of the threaded rods 63. The bottom end of the filter screen 64 is fixedly connected to a liquid recovery tank 66. A drain valve 67 is fixedly installed at the bottom of the liquid recovery tank 66. The bottom end of L-shaped support rod 1 53 is fixedly connected to an impact box 68. The impact boxes 68 on the left and right sides are equipped with anti-adhesion mechanisms.

[0052] The anti-adhesion mechanism inside the impact box 68 on the left side includes: a rotating rod 69, several rotating rods 69 are rotatably connected inside the impact box 68, a spur gear 70 is fixedly connected to the top of the rotating rod 69, an impact hammer 76 is fixedly connected to the bottom of the rotating rod 69, an anti-collision pad 72 is provided below the impact hammer 76, the anti-collision pad 72 is fixedly connected to the bottom wall of the vibration box 43, the spur gear 70 meshes with a horizontal rack 73, a spring 74 is fixedly connected to the left end of the horizontal rack 73, the spring 74 is fixedly connected to the left wall of the impact box 68, the horizontal rack 73 is slidably connected to the right wall of the impact box 68, an L-shaped support rod 75 is fixedly connected to the right end of the horizontal rack 73, a roller 71 is rotatably connected to the top of the L-shaped support rod 75, the roller 71 presses against a wedge block 33 that is higher on the left and lower on the right, and the wedge block 33 is fixedly connected to the top wall of the vibration box 43.

[0053] The working principle of the above technical solution is as follows: After the granular material is sprayed, it easily sticks to the inner wall of the pipe at the outlet of the mixing box 39 and cannot be cleared. At this time, the spraying clearing and recovery device 42 starts to work. The drive motor 45 drives the rotating shaft 46, pulley 47 and spur gear 54 to rotate. The pulley 47 drives the pulleys 48 on both sides and the cylindrical cam 50 to rotate synchronously through the belt 49. The cylindrical cam 50 drives the L-shaped support rod 53 to slide in the groove 51. The L-shaped support rod 53 slides up and down in the sliding sleeve 52. The L-shaped support rod 53 drives the impact box 68 and the impact hammer 76 to repeatedly strike the anti-collision pad 72. The vibration causes the bottom wall of the vibrating box 43 and the pipe wall of the mixing box 39 to vibrate together. This vibration causes the feed pellets to fall off, thereby clearing the pipes. At the same time, the anti-sticking mechanism works. The roller 71 rolls on the wedge block 33, which drives the L-shaped support rod 75 to move up and down and left and right. This causes the horizontal rack 73 to slide left and right, driving the spur gear 70, the rotating rod 69 and the impact hammer 76 to rotate synchronously, preventing the anti-collision pad 72 from sticking due to impact. The spur gear 54 drives the spur gear 56, the rotating shaft 55 and the fan blades 57 to rotate synchronously, thereby forming hot air in the air collection duct 58, which dries the pellets to a certain extent and prevents them from clumping.

[0054] At the same time, when the L-shaped support rod 53 slides up and down, it drives the L-shaped support rod 60, the crossbar 62, the threaded rod 63, the threaded sleeve 65 and the filter screen 64 to vibrate synchronously to filter out excess sprayed liquid in the granular material, which then falls into the liquid recovery tank 66. When a certain amount is collected, the drain valve 67 is opened to recover the liquid. The front and rear threaded rods 63 rotate at different heights in the crossbar 62 to make the filter screen 64 tilt forward at a certain slope.

[0055] The beneficial effects of the above technical solution are as follows: The spraying and unblocking recovery device 42 is beneficial for the granules to be sprayed with grease and nutrient solution. After the granules are mixed, the inner wall of the mixing box 39 is better unblocked, which can better improve the recovery of grease and spray liquid. The filter screen 64 and the liquid recovery box 66 more effectively recover the excess grease and spray liquid after the granules are mixed, improve the utilization rate of spray liquid and unblock the granules in time, and prevent the formation of adhesion to the inner wall and blockage. The filter screen 64 can be manually adjusted by adjusting the height of the front and rear threaded rods 63. When it needs to be tilted forward, the rear threaded rod 63 is twisted upward in the crossbar 62, so that the rear end of the filter screen 64 is higher than the front end. The tilted filter screen 64 makes it easier for the granules to flow out during filtration.

[0056] Example 4, based on any one of Examples 1-3, further includes:

[0057] A temperature sensor is used to detect the temperature of the grease in the weighing tank 10;

[0058] The feed information acquisition module is used to acquire feed information, including: the friction coefficient between feed particles and the friction coefficient between feed and the inner wall of the mixing box 39.

[0059] The control device is used to control the operation of the screw rod based on the temperature sensor and the feed information acquisition module, including: calculating the target speed of the screw rod based on the feed information acquisition module and controlling the operation of the mixing motor 30 so that the actual speed of the screw rod 38 is the target speed.

[0060] ;

[0061] The target rotational speed of the screw; sin is the sine wave. Let be the helix angle of the helical blade of screw rod 38, and g be the acceleration due to gravity. The coefficient of friction between feed pellets. Let be the friction angle of the helical surface of the helical blade of the screw rod. The target lifting angle for the feed (the feed pellets rise to a certain position before falling to ensure mixing effect); The angle between the axis of the screw and the horizontal direction; Let be the radius of the helical blade. The radius of the screw shaft; The coefficient of friction between the feed pellets and the pipe wall. is the coefficient of friction between the grease and the pipe wall; ln is the natural logarithm, and e is the natural constant; The value is 3.14;

[0062] This is the value detected by the temperature sensor. The standard temperature for oils; for Compared to The coefficient of influence of changes on oil mixing (values ​​are greater than -1 and less than 1); for Compared to The influence coefficient of the change on the oil conveying speed (with a value greater than -1 and less than 1); the above represent °.

[0063] The beneficial effects of the above technical solution are: by selecting a suitable rotational speed of the screw, the conveying and mixing effect can be guaranteed;

[0064] Furthermore, the calculation of the screw rotation speed takes into account the target lifting angle of the feed (the feed particles are lifted to a certain position and then fall to ensure the mixing effect), the friction coefficient between feed particles, the friction angle of the spiral surface of the screw blade, the friction coefficient between the oil and the pipe wall, and the friction coefficient between the feed particles and the pipe wall, making the calculation reliable.

[0065] Example 5, based on any one of Examples 1-4, further includes a horizontal tube 27 detachably connected to the bottom of the rotating vertical tube 26, and also includes:

[0066] The memory stores a standard parameter table, which is set with the following parameters: the ratio of feed particle weight to oil weight corresponding to different feed parameters (including feed type and feed size), oil parameters (including oil type and oil temperature) and spraying requirements; and the standard flow rate of the nozzle corresponding to different feed parameters (including feed type and feed size), oil parameters (including oil type and oil temperature) and spraying requirements.

[0067] A feed detection device is installed at the discharge port 41 to obtain information about the sprayed feed. The feed detection device includes: a feed spreading and receiving box for spreading and receiving the feed discharged from the discharge port 41; and a camera device for obtaining images of the sprayed feed in the spreading and receiving box.

[0068] The control device is electrically connected to the first weighing sensor, the second weighing sensor, and the memory, respectively.

[0069] Before batch mixing, a mixing test is conducted. During the mixing test, the control device controls the metering mechanism to dispense feed pellets according to the weight of the first feed pellet, and controls the actual flow rate of the nozzle to be the standard flow rate and the actual working power of the mixing motor to be the rated working power. The process continues until the weight of the first oil is dispensed, and then the feed detection device is used for testing. The ratio of the weight of the first feed pellet to the weight of the first oil meets the standard parameter table.

[0070] The processing device is electrically connected to the camera device. The processing device includes: a first acquisition module for acquiring an actual image of the sprayed feed in a flat receiving box captured by the camera device; a division module for dividing the actual image of the sprayed feed in the flat receiving box into several first sub-images; a separation module for separating the background and foreground of the first sub-images to obtain a first sub-foreground image and a first sub-background image; a grayscale processing module for performing grayscale processing on the first sub-foreground image and the first sub-background image; a grayscale value extraction module for extracting the grayscale values ​​of multiple pixels from the first sub-foreground image and the first sub-background image; and a calculation module for calculating the oil surplus on the feed pellets and the environmental oil surplus.

[0071] ;

[0072] ;

[0073] This refers to the oil surplus on feed pellets. The number of the first sub-foreground images, This represents the number of pixels selected from the first sub-foreground image; Let be the grayscale value of the j-th pixel in the i-th first sub-foreground image; The target pixel for the coated feed; The number of the first sub-background images. This represents the number of pixels selected from the first sub-background image; Let be the grayscale value of the s-th pixel in the k-th first sub-background image. The target pixels in the background image that are not contaminated with grease; This is a compensation coefficient based on the remaining state of the grease in the mixing chamber (which can be obtained from the remaining volume of the grease in the mixing chamber and a preset table of remaining volume of the grease in the mixing chamber minus the compensation coefficient); its value is greater than 0 and less than 1). For environmental oil surplus;

[0074] When insufficient oil content is determined based on the oil surplus on feed pellets (e.g., when the gray value increases after feed pellets are covered with oil), If the value is greater than the corresponding first preset value, then the oil content is determined to be excessive; If the value is less than the corresponding second preset value, it is determined that the oil content is insufficient (the second preset value is less than the first preset value). Simultaneously, based on the environmental oil surplus, it is determined that the environmental oil content exceeds the standard (e.g., when the grayscale value increases after the environment is covered with oil). If the value is greater than the corresponding third preset value, it is determined that the grease content exceeds the standard. Reduce the flow rate of the nozzle to the corresponding third flow rate and increase the length of the horizontal tube 27.

[0075] ;

[0076] As the third flow, This is the second flow rate adjustment coefficient (with a value greater than 0 and less than 0.7). Determine the threshold value for excessive environmental oil content to determine the environmental oil surplus (which can be the third preset value mentioned above). The standard flow rate of the nozzle corresponding to the spraying requirements (the actual required nozzle flow rate may vary due to differences between the actual feed parameters and the standard parameters or differences in the actual components within the mixing tank).

[0077] When the oil content is determined to be insufficient based on the oil surplus on the feed pellets, and the environmental oil content is determined to be qualified based on the environmental oil surplus, maintain the nozzle flow rate and increase the length of the horizontal tube 27 (increase the spraying range and select horizontal tubes of different lengths).

[0078] When the oil content is determined to be insufficient based on the oil surplus on the feed pellets, and the environmental oil content is determined to be insufficient based on the environmental oil surplus, the nozzle flow rate is increased to the fourth flow rate, and the length of the horizontal tube 27 is increased (to increase the spraying range).

[0079] ; As the fourth flow, This is the first flow rate adjustment coefficient (with a value greater than 0 and less than 1). When determining the acceptable oil content for feed pellets and the acceptable environmental oil content for the same purpose, the oil content on the feed pellets must be within acceptable limits. Standard value;

[0080] When the oil content is determined to be excessive based on the oil surplus on the feed pellets, and the environmental oil content is determined to be excessive or acceptable based on the environmental oil surplus, the flow rate of the nozzle is reduced to obtain a second flow rate, while maintaining the length of the horizontal tube 27.

[0081] ; For the second flow, This is the first flow rate adjustment coefficient (with a value greater than 0 and less than 1). When determining the acceptable oil content for feed pellets and the acceptable environmental oil content for the same purpose, the oil content on the feed pellets must be within acceptable limits. Standard value;

[0082] When the oil content is determined to be within acceptable limits based on the oil surplus on the feed pellets, and the environmental oil content is determined to be exceeding the limit based on the environmental oil surplus, the nozzle flow rate is reduced to the third flow rate, while maintaining the length of the horizontal tube 27.

[0083] When the oil content is determined to be qualified based on the oil surplus on the feed pellets, and the environmental oil content is determined to be qualified based on the environmental oil surplus, the flow rate of the nozzle is maintained, and the length of the horizontal tube 27 is maintained.

[0084] The beneficial effects of the above technical solution are as follows: the control device controls the metering mechanism to feed feed pellets according to the weight of the first feed pellet, and controls the actual flow rate of oil in the rotating vertical pipe to the standard flow rate and the actual working power of the mixing motor to the rated working power, and works until the weight of the first oil is fed, and then is detected by the feed detection device; that is, before formal batch mixing, a mixing test is first carried out, and the appropriate nozzle flow rate and appropriate spraying range (corresponding to the length of the horizontal pipe 27) are selected according to the test results before batch mixing, so as to ensure the mixing effect.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
