Description

Technical Field

[0002] In fertilizer production, moisture content is a key indicator determining product quality, storage stability, and effectiveness. Excessive moisture content can lead to granule clumping, mold growth during storage, and reduced flowability during application. Conversely, insufficient moisture content results in over-drying, increasing unnecessary energy consumption and production costs.

Existing fertilizer drying equipment typically uses laser detection mechanisms to measure the moisture content in the drying area. However, during the drying process, hot air blows through the drying area, and the water vapor and temperature in the hot air interfere with the absorption of the laser signal, causing inaccurate laser detection.

[0043] S4. After the test is completed, adjust the second mounting base to move upward to extend into the interior of the device body, and drive the fertilizer located inside the second mounting base to the support for continued drying.

[0044] The online moisture content detection device and method for fertilizer drying process of the present invention have the following advantages over the prior art:

[0045] (1) This application provides a bottom assembly box at the bottom of the device body, which can be used as a separate sampling and testing area for fertilizer, facilitating fertilizer sampling and testing. It also facilitates the return of the extracted fertilizer sample to the inner cavity of the device body for further drying after testing. By providing ventilation holes on the first, second, and third supports, the supports can ensure proper ventilation during fertilizer drying. Furthermore, the bottom of the second support is sealed, and the third support is mounted on a baffle cover. In practical implementation, this design allows for… The bottom wall of the second support and the baffle cover can both block the drying air, preventing it from entering the interior of the bottom assembly box and causing abnormal temperature inside. At the same time, by setting up the baffle cover to collect the drying air, the drying air at the third support can be blown back into the interior of the device body from below for discharge, without affecting the normal drying process of the fertilizer at the third support. By setting up a laser detection mechanism to perform laser moisture content detection inside the closed bottom assembly box, the drying air generated during the drying process can be prevented from interfering with the laser detection, making it convenient to use.

[0046] (2) By setting up a laser detection mechanism including an upper mounting base, a connecting base and a support base, when the fertilizer is dropped into the bottom assembly box by opening the third support base, the fertilizer sample to be tested will be stored on the support base. Since dust will be generated during the drying process of the fertilizer, by setting the laser detection machine below the upper mounting base, the dust generated during the drying process can be prevented from interfering with the normal detection of the laser detection machine. After the dust is removed, the support base can be lowered to the laser detection machine by adjusting the end of the light-transmitting membrane belt. Since the light-transmitting membrane belt is connected to the first connecting roller and the first mounting groove is connected to the top of the support base, when the support base is lowered to the lower mounting base, the light-transmitting membrane belt can be aligned with the side wall of the support base and extend from the top of the support base, so that the fertilizer sample can be maintained on the support base. The laser is emitted by the laser detection machine and passes through the light-transmitting membrane belt to complete the detection of the moisture content of the fertilizer sample.

[0047] (3) By setting a first driving plate and a second driving plate on the upper mounting base, in specific implementation, the first mounting base can be adjusted to rise so that the support base is located inside the device body. Then, the second driving plate can be adjusted to move to drive the fertilizer sample onto the first support, thereby feeding the fertilizer back into the device body. By setting the number of driving plates to two, when the first mounting base rises, the second driving plate can cooperate with the first driving plate to drive the fertilizer on the support base onto the first support. At the same time, when the first mounting base falls, there can be no fertilizer residue on the support base. By setting the tops of the mounting base, connecting base and support base to be aligned, it is convenient to adjust the movement of the second driving plate and to use it conveniently.

[0060] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0061] like Figures 1-10As shown, the online moisture content detection device for fertilizer drying process of the present invention includes a device body 1, a first support 21, a second support 22, an assembly frame 23, an air baffle cover 24, a third support 25, a first assembly base 31, a second assembly base 32, and a laser detection mechanism 4. The bottom end of the device body 1 forms a bottom assembly box 11. The first assembly base 31 is disposed inside the bottom assembly box 11, and a sliding protrusion 311 is provided on the first assembly base 31. The second assembly base 32 is slidably sleeved on the sliding protrusion 311. The first support 21 is disposed inside the device body 1, and the second support 22 is disposed on the second assembly base 32. The first support 21 and the second support 22 are connected together. The assembly frame 23 is disposed below the second support 22. Furthermore, the baffle box 24 is hinged to the assembly frame 23, and the baffle box 24 is used to rotate to be assembled on one side of the second support 22; the third support 25 is set on the baffle box 24, and the third support 25 is assembled and connected to the second support 22; the first support 21, the second support 22 and the third support 25 are all used to support fertilizer, and the first support 21, the second support 22 and the third support 25 are all provided with ventilation holes 211. The bottom end of the second support 22 is closed, and the bottom end of the first support 21 is provided with an air guide groove 212 that communicates with the ventilation holes 211 on the second support 22; the device body 1 is provided with a drying mechanism 12 for drying fertilizer; the laser detection mechanism 4 is set inside the second assembly base 32 and is used to detect the moisture content of fertilizer by laser.

[0062] In practice, fertilizer is stored on the first support 21, the second support 22, and the third support 25, and dried by the drying mechanism 12. The drying air generated by the drying mechanism 12 blows onto the surface of the fertilizer to dry it. The drying air blowing onto the first support 21 is directly blown out through the vent 211 on the first support 21. The drying air blowing onto the second support 22 is blocked by the bottom wall of the second support 22 and discharged from below the first support 21 through the air guide groove 212. The drying air blowing onto the third support 25 is... The baffle 24 blocks and refluxes the fertilizer from below to dry it. When the fertilizer moisture content needs to be tested, the baffle 24 is rotated, and the fertilizer stored on the third support 25 will fall down into the bottom assembly box 11 to complete the fertilizer sampling process. The moisture content of the fertilizer is tested by the laser testing machine 48. After the test is completed, the second assembly seat 32 is moved upward to extend into the interior of the device body 1, and the fertilizer located inside the second assembly seat 32 is driven onto the support for further drying.

[0063] This application provides a bottom assembly box 11 below the device body 1, which serves as a separate sampling and testing area for fertilizer. This facilitates fertilizer sampling and testing, and also allows the extracted fertilizer samples to be re-introduced into the inner cavity of the device body 1 after testing for further drying. Ventilation holes 211 are provided on the first support 21, second support 22, and third support 25, ensuring that the supports do not interfere with the drying and ventilation of the fertilizer. The second support 22 has a closed bottom, and the third support 25 is mounted on a baffle cover 24. Therefore, in practical implementation… The bottom wall of the second support 22 and the baffle 24 can both block the drying air, causing the drying air to enter the interior of the bottom assembly box 11, which in turn causes abnormal temperature inside the bottom assembly box 11. At the same time, by setting the baffle 24 to collect the drying air, the drying air at the third support 25 can be blown back into the interior of the device body 1 from below for discharge, without affecting the normal drying treatment of fertilizer at the third support 25. By setting the laser detection mechanism 4 to perform laser moisture content detection inside the closed bottom assembly box 11, the drying air generated during the drying process can be prevented from interfering with the laser detection, making it convenient to use.

[0064] In a preferred embodiment, there are two first supports 21, and the two first supports 21 are symmetrically arranged on both sides of the inner cavity of the device body 1. The side wall of the third support 25 is provided with a first extension protrusion 251 extending out of the air baffle cover 24. The second support 22 is provided with an insertion groove 221 for the first extension protrusion 251 to be inserted. The side wall of one side of the third support 25 is provided with a second extension protrusion 252 for insertion into the third support 25 on the other side.

[0065] This design aims to improve the stability of the third support 25 when closed without affecting its rotation.

[0066] In a preferred embodiment, the laser inspection mechanism 4 includes an upper mounting base 41, a connecting base 42, a support base 43, a first connecting roller 44, a light-transmitting film belt 45, a limiting roller 46, and a laser inspection machine 48. The upper mounting base 41 is mounted on a second mounting base 32, and the connecting base 42 is fixedly connected to one side of the upper mounting base 41. The support base 43 is movably connected to one side of the connecting base 42. A first mounting groove 431 is formed on the top of the support base 43, communicating with the side of the support base 43 near the connecting base 42. The first connecting roller 44 is rotatably mounted on the upper mounting base 41. The inner side of the mounting groove 431; the bottom of the connecting seat 42 is provided with a second mounting groove 421, which is connected to the side of the connecting seat 42 near the support seat 43. The light-transmitting film belt 45 is fixedly connected to the first connecting roller 44 and is located inside the second mounting groove 421. The light-transmitting film belt 45 is a light-transmitting polyester film belt. The limiting roller 46 is set inside the second mounting groove 421 and is located below the light-transmitting film belt 45. It is used to limit the bending deformation of the light-transmitting film belt 45 along the limiting roller 46. The laser detection machine 48 is set below the upper mounting seat 41 and is used to detect the moisture content of the fertilizer by laser.

[0067] The laser inspection mechanism 4 also includes a lower mounting base 47 and a telescopic cylinder 49. The lower mounting base 47 is disposed on the second mounting base 32 and located below the upper mounting base 41. The lower mounting base 47 has a mating slot 471 for the support base 43 to be inserted into. The laser inspection machine 48 is disposed on one side of the mating slot 471. The telescopic cylinder 49 is disposed inside the bottom mounting box 11, and the telescopic end of the telescopic cylinder 49 is fixedly connected to the lower mounting base 47.

[0068] By setting up the laser detection mechanism 4, which includes an upper mounting base 41, a connecting base 42, and a support base 43, when the fertilizer falls into the bottom assembly box 11 by opening the third support 25, the fertilizer sample to be tested will be stored on the support base 43. Since dust will be generated during the drying process of the fertilizer, by placing the laser detection machine 48 below the upper mounting base 41, the dust generated during the drying process can be prevented from interfering with the normal detection of the laser detection machine 48. After the dust is removed, the end of the light-transmitting membrane belt 45 can be adjusted. The support 43 is moved down to the laser inspection machine 48. Since the light-transmitting film belt 45 is connected to the first connecting roller 44 and the first mounting groove 431 is connected to the top of the support 43, when the support 43 is lowered onto the lower mounting seat 47, the light-transmitting film belt 45 can be aligned with the side wall of the support 43 and extend from the top of the support 43, so that the fertilizer sample can be maintained on the support 43. The laser emitted by the laser inspection machine 48 passes through the light-transmitting film belt 45 to complete the moisture content detection process of the fertilizer sample.

[0069] In a preferred embodiment, the assembly further includes a material driving component 5, which includes a first material driving plate 51, a second material driving plate 52, and a traction belt 53. The top ends of the upper mounting base 41, the connecting base 42, and the support base 43 are aligned. The first material driving plate 51 is disposed on one side of the top end of the upper mounting base 41, and the second material driving plate 52 is slidably disposed on one side of the first material driving plate 51, sliding towards or away from the first material driving plate 51. The traction belt 53 is connected to the second material driving plate 52 and is used to pull the second material driving plate 52 to slide.

[0070] By setting a first driving plate 51 and a second driving plate 52 on the upper mounting base 41, in specific implementation, the first mounting base 31 can be raised to position the support base 43 inside the device body 1. Then, the second driving plate 52 can be moved to drive the fertilizer sample onto the first support base 21, thereby feeding the fertilizer back into the device body 1. By setting two driving plates, when the first mounting base 31 rises, the second driving plate 52 can cooperate with the first driving plate 51 to drive the fertilizer on the support base 43 onto the first support base 21. At the same time, when the first mounting base 31 descends, there can be no fertilizer residue on the support base 43. By aligning the tops of the upper mounting base 41, connecting base 42, and support base 43, it is easy to adjust and move the second driving plate 52, making it convenient to use.

[0071] It also includes a second connecting roller 54, wherein a third mounting groove 521 is provided on the side of the second driving plate 52 away from the first driving plate 51, and the third mounting groove 521 is connected to the lower part of the second driving plate 52; there are two upper mounting seats 41, and the two upper mounting seats 41 are respectively provided with a connecting groove 413 and a connecting hole 414. The connecting groove 413 is connected to the top of the upper mounting seat 41 and the side of the upper mounting seat 41 away from the other side of the upper mounting seat 41. The traction belt 53 passes around the second connecting roller 54, the connecting groove 413 and the connecting hole 414.

[0072] This design, by setting the traction belt 53 to be connected to the second connecting roller 54 and the third mounting groove 521 to be connected to the lower part of the second driving plate 52, allows the traction belt 53 to move the second driving plate 52 so that the second driving plate 52 can be moved to be aligned with the end of the support base 43 and the end of the mounting base 41 on one side, which facilitates the complete supply of the extracted fertilizer sample to the support.

[0073] In a preferred embodiment, the system further includes a connecting plate base 61, a drive screw 62, and a drive motor 63. The upper mounting base 41 is an L-shaped base, including a vertical base 411 and a horizontal base 412 that are perpendicularly connected to each other. The connecting base 42 is disposed on the vertical base 411. The connecting plate base 61 is slidably disposed inside the second mounting groove 421, and the light-transmitting film strip 45 is fixedly connected to the connecting plate base 61. The drive screw 62 is rotatably disposed on the vertical base 411 and threadedly connected to the connecting plate base 61. The drive motor 63 is disposed on the horizontal base 412 and is used to drive the drive screw 62 to rotate.

[0074] In practice, the drive screw 62 is driven to rotate by the drive motor 63, and the drive roller connecting plate seat 61 moves along the second mounting groove 421 through the thread action of the drive screw 62, thereby completing the automatic lifting and lowering adjustment of the support seat 43.

[0075] In a preferred embodiment, the system also includes a bottom mounting frame 71 and a traction roller 72, wherein the bottom mounting frame 71 is mounted on the upper mounting base 41, and the traction roller 72 is rotatably mounted on the bottom mounting frame 71, and the traction belt 53 is wound around the traction roller 72.

[0076] In practice, the traction belt 53 is moved by adjusting the rotation of the traction roller 72.

[0077] In a preferred embodiment, an exhaust chamber 13 is formed between the bottom assembly box 11 and the side wall of the device body 1. A ventilation hole 131 is provided between the multiple exhaust chambers 13 and communicates with each other. An exhaust pipe 14 is provided on the side wall of the device body 1 and communicates with the exhaust chamber 13. A dust suction hole 321 is provided on the second assembly seat 32. The dust suction hole 321 is located above the upper mounting seat 41. A dust suction pipe 15 is connected to the side wall of the bottom assembly box 11.

[0078] In practice, the drying gas is discharged through the exhaust pipe 14 and connected to an external dust collection device through the dust collection pipe 15 to complete the dust collection treatment inside the bottom assembly box 11.

[0079] This invention also proposes an online moisture content detection method for fertilizer drying process, which is accomplished using the aforementioned online moisture content detection device for fertilizer drying process, and includes the following steps:

[0080] Step 1: Store the fertilizer on the first support 21, the second support 22 and the third support 25, and dry the fertilizer through the drying mechanism 12. At this time, the drying air generated by the drying mechanism 12 blows on the surface of the fertilizer to dry it. The drying air blown on the first support 21 is directly blown out through the vent 211 opened on the first support 21. The drying air blown on the second support 22 is blocked by the bottom wall of the second support 22 and discharged from the bottom of the first support 21 through the air guide groove 212. The drying air blown on the third support 25 is blocked by the air baffle cover 24 and flows back to dry the fertilizer from below.

[0081] Step 2: When it is necessary to test the moisture content of fertilizer, adjust the rotation of the baffle box cover 24. At this time, the fertilizer stored on the third support 25 will fall down into the bottom assembly box 11, completing the fertilizer testing and sampling process.
