Description

Technical Field

[0001] This utility model relates to the technical field of water-soluble fertilizer processing equipment, and in particular to a drying equipment for water-soluble fertilizer. Background Technology

[0002] Water-soluble fertilizers, as a type of fast-acting fertilizer, are widely used in modern agricultural production. In their production process, drying is a crucial step to ensure product quality, prevent clumping, and facilitate storage. Therefore, various types of drying equipment are typically used to remove excess moisture from fertilizer granules through methods such as hot air.

[0003] In existing water-soluble fertilizer drying equipment, the drying component that generates hot air is one of the most crucial parts. This component typically includes a fan and heating device, and needs to operate continuously for extended periods under high temperature and high load conditions. Therefore, the drying component is a consumable part, requiring regular maintenance and replacement when its service life expires or when it malfunctions.

[0004] However, some existing drying equipment often integrates the drying components as fixed units within the main frame of the equipment. When maintenance or replacement of the drying components is required, repair personnel must first disassemble numerous peripheral components, such as the casing, protective covers, and even parts of the transmission mechanism, before they can access the core drying components. The entire disassembly and assembly process is cumbersome, complex, and requires significant downtime.

[0005] This prolonged downtime due to maintenance directly impacts the production efficiency of the entire production line, causing unnecessary economic losses. Furthermore, the complex disassembly and assembly process not only increases maintenance labor costs and intensity but also makes it difficult to adapt to the rapid replacement of different models of drying components under varying production needs, significantly limiting the equipment's versatility and flexibility.

[0006] Therefore, this utility model proposes a drying device for water-soluble fertilizers to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems of complex maintenance and replacement process, long time consumption and poor versatility of the core drying components in the existing water-soluble fertilizer drying equipment, this utility model aims to provide a water-soluble fertilizer drying equipment with improved structure that can effectively solve the above problems.

[0008] This utility model provides a drying device for water-soluble fertilizer, including: a base, a crushing mechanism, a drying component; and a replacement mechanism and a quick-release mechanism for maintaining and replacing the drying component.

[0009] The crushing mechanism includes a drum that is rotatably supported on a base by two rotating columns at both ends. The drum is provided with a feed inlet and a discharge outlet.

[0010] The replacement mechanism includes a base, slide rail, base plate, motor, hydraulic rod, and telescopic rod. The slide rail is fixedly installed on the base, and the base plate is slidably connected to the slide rail. The motor drives the hydraulic rod to push the base plate to move along the slide rail. Furthermore, the telescopic rod, connecting plate, and connecting column are combined to form a linkage relationship between the telescopic rod and the base plate.

[0011] The quick-release mechanism includes a clamping plate, a second connecting post, a baffle, a locking ball, and a spring. The clamping plate is driven by a telescopic rod to clamp or release the drying assembly. The second connecting post is fixedly connected to the bottom of the clamping plate, and the baffle is fixedly connected to the second connecting post. The locking ball and spring are located inside the base plate, and the clamping plate can be quickly replaced by the squeezing action of the baffle.

[0012] Preferably, the outside of the drum is provided with multiple tracks, and the drum rotates along the tracks; the circumferential arrangement of the rotating column two is provided with lifting plates, which are used to crush and lift the material during the rotation of the drum.

[0013] Preferably, a filter screen is installed inside the discharge port, and multiple sets of scrapers are installed radially inside the filter screen; when the rotating column rotates, it drives the scrapers to rotate to remove the raw material adhering to the filter screen.

[0014] Preferably, the drying assembly includes a housing, a fixing plate, a fixing column, a rotating shaft, and fan blades; the housing is fixedly connected to the base via the fixing plate and fixing column at its bottom, the rotating shaft is installed inside the housing, and the fan blades are fixed on the rotating shaft.

[0017] Preferably, the locking ball and the spring are connected in series in the receiving cavity inside the base plate, and the baffle compresses the spring to make the locking ball disengage from or clamp the clamp.

[0018] Preferably, the air outlet of the drying component corresponds to the air inlet opened on the drum wall to send hot air into the drum.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model, by setting up a replacement mechanism and a quick-release mechanism, uses a motor-driven sliding base plate linkage clamp to achieve rapid loosening and locking of the drying components, which solves the problems of complex, time-consuming and poor versatility of the maintenance and replacement process of the core drying components of the existing drying equipment. It achieves the technical effects of quickly replacing different models of drying components, shortening equipment downtime for maintenance, and improving the flexibility and efficiency of equipment use.

[0021] 2. This utility model solves the problems of water-soluble fertilizer raw materials being prone to clumping due to moisture, insufficient material turning during the drying process, and low drying efficiency and uneven effect by setting lifting plates inside the rotating drum, which continuously tumbles, scatters and crushes the material when the drum rotates.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0035] Example:

[0036] Please refer to Figures 1 to 5 This utility model provides a drying device for water-soluble fertilizer, which aims to solve the problems of complex maintenance and replacement process of core drying components, long time consumption and poor equipment versatility in the prior art.

[0037] like Figure 1 As shown, the water-soluble fertilizer drying equipment includes a base 1, a crushing mechanism 4 installed on the base 1, a drying component 3 fixedly connected to the base 1, a replacement mechanism 2 for maintaining and replacing the drying component 3, and a quick-release mechanism 5. The base 1 serves as the mounting base for the entire equipment and supports all other components.

[0038] The replacement mechanism 2 includes a base 21, a slide rail 28, a base plate 24, a motor 22, a hydraulic rod 23, a telescopic rod 27, a connecting plate 25, and a connecting column 26. The base 21 is fixedly installed on one side of the base 1. The slide rail 28 is fixedly installed on the base 21. The base plate 24 is slidably connected to the slide rail 28 and can reciprocate on the slide rail 28. The motor 22 is fixedly installed on the side of the base 21. The motor 22 drives the hydraulic rod 23. One end of the hydraulic rod 23 is linked with the motor 22, and the other end is connected to the base plate 24 to push the base plate 24 to move along the slide rail 28. The telescopic rod 27 is linked with the base plate 24 through the connecting plate 25 and the connecting column 26. Specifically, one end of the connecting column 26 is connected to the telescopic rod 27, and the other end is connected to the connecting plate 25. The connecting plate 25 is fixedly connected to the base plate 24.

[0039] The quick-release mechanism 5 includes a clamping plate 51, a connecting post 52, a baffle 53, a locking ball 54, and a spring 55. The clamping plate 51 is driven by the telescopic rod 27 to clamp or release the drying assembly 3. The connecting post 52 is fixedly connected to the bottom of the clamping plate 51, and the baffle 53 is fixedly connected to the connecting post 52. The locking ball 54 and the spring 55 are located inside the base plate 24. More specifically, the locking ball 54 and the spring 55 are connected in series in the receiving cavity inside the base plate 24. When the clamping plate 51 is replaced, the baffle 53 squeezes the spring 55, causing the locking ball 54 to disengage from or clamp the clamping plate 51, thereby completing the quick replacement of the clamping plate 51.

[0040] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The main structure of the crushing mechanism 4 is a drum 41. The drum 41 is rotatably supported on the base 1 by rotating columns 44 and 46 at both ends. It can rotate along multiple tracks 48 set on its exterior. Its function is to provide a working chamber for crushing and drying water-soluble fertilizer raw materials. The top of the drum 41 is provided with a feed inlet 49 for feeding raw materials, and the end of one side of the drum 41 is provided with a discharge outlet 42 for discharging processed materials.

[0041] The rotating column 46 is circumferentially arranged with lifting plates 47. During the rotation of the drum 41, these lifting plates 47 continuously tumble, lift and scatter the raw materials inside the drum 41, thereby achieving the chopping and crushing of the raw materials and making the raw materials evenly dispersed and fully dried. This design of the lifting plates 47 ensures the efficient processing and rapid crushing of materials in the drum 41.

[0042] The discharge port 42 is equipped with a filter screen 43 for screening crushed material particles. Multiple sets of scrapers 45 are installed radially inside the filter screen 43. When the rotating column 44 rotates, it drives the scrapers 45 to rotate synchronously. The function of the scrapers 45 is to remove the raw material attached to the filter screen 43, prevent the filter screen 43 from clogging, and ensure that the material can be discharged continuously and smoothly through the discharge port 42.

[0043] Meanwhile, the drying assembly 3 is activated after the raw material enters the drum 41. The drying assembly 3 includes a shell 31, a fixing plate 32, a fixing column 33, a rotating shaft 34, and a fan blade 35. The bottom of the shell 31 is fixedly connected to the base 1 through the fixing plate 32 and the fixing column 33. The rotating shaft 34 is installed inside the shell 31, and the fan blade 35 is fixed on the rotating shaft 34. The rotating shaft 34 is driven to rotate by an external drive source to generate uniform hot air. The air outlet of the drying assembly 3 corresponds to the air inlet opened on the drum wall of the drum 41, and sends hot air into the drum 41 to efficiently dry the material that is continuously lifted by the lifting plate 47.

[0044] Reference Figure 1 and Figure 2Multiple annular tracks 48 are fixedly connected to the outer peripheral wall of the roller 41. These tracks 48 roll in cooperation with the support rollers on the base 1, providing stable support and guidance for the rotation of the roller 41; see reference. Figure 2 Multiple lifting plates 47 are uniformly fixedly connected along the axial direction on the circumferential surface of the rotating column 46. The lifting plates 47 are plate-shaped structures with a certain inclination angle, which can efficiently turn and crush materials.

[0045] In another preferred embodiment, in order to ensure the uniformity of the discharged particles and prevent the discharge port 42 from being blocked, a filter screen 43 is fixedly installed inside the discharge port 42. The filter screen 43 is a screen structure with a preset aperture. The rotating column 44 extends into the interior of the filter screen 43, and multiple sets of scrapers 45 are radially fixedly installed on the rotating column 44. The outer edges of these scrapers 45 maintain a small gap or elastic contact with the inner surface of the filter screen 43 to continuously clean the screen.

[0046] Reference Figure 1 and Figure 5 The main body of the drying component 3 is the outer shell 31. A fixing plate 32 is integrally formed or welded to the bottom of the outer shell 31. The fixing plate 32 is securely connected to the base 1 via fixing posts 33 and fasteners. (Refer to...) Figure 5 The housing 31 has a rotating shaft 34 inside. The two ends of the rotating shaft 34 are rotatably supported on the housing 31 by bearings. Multiple sets of fan blades 35 are fixed on the rotating shaft 34 in an intermittent arrangement.

[0047] The top of the replacement mechanism 2 is also provided with a cover 29, which is fixedly connected to the top of the outer shell 31 of the drying component 3 by a buckle or screw, thus covering and protecting the moving parts such as the telescopic rod 27 and the connecting plate 25.

[0048] Reference Figure 1 and Figure 4 The base plate 24 has an internal cavity, in which the spring 55 and the locking ball 54 are connected in series; see reference. Figure 4 One end of the spring 55 abuts against the bottom of the receiving cavity, and the other end contacts the locking ball 54. In its natural state, the spring 55 pushes the locking ball 54 to protrude from the surface of the base plate 24, so as to lock into the positioning groove at the bottom of the clamping plate 51.

[0049] The motor 22 is fixedly installed on the side of the base 21 away from the roller 41, which facilitates maintenance and does not interfere with other moving parts.

[0050] The outer shell 31 of the drying component 3 is provided with an air outlet, and the corresponding position of the drum wall of the drum 41 is provided with an air inlet. In the installed state, the air outlet of the drying component 3 is aligned with the air inlet of the drum 41 and connected by a sealing ring to ensure that hot air can enter the inside of the drum 41 to the maximum extent and reduce heat loss.

[0051] The working principle is as follows:

[0052] During normal water-soluble fertilizer processing, the raw material enters the drum 41 through the feed inlet 49 at the top of the crushing mechanism 4. The drive device supports the drum 41 on the base 1 via the first rotating column 44 and the second rotating column 46 at both ends, and rotates along the external track 48. During the rotation of the drum 41, the lifting plates 47 fixed around the second rotating column 46 continuously tumble, chop, and scatter the raw material to achieve material crushing. At the same time, the drying component 3 starts working, and the internal rotating shaft 34 drives multiple sets of fan blades 35 to rotate, generating uniform hot air. The hot air enters the air inlet of the drum 41 through the air outlet of the drying component 3, efficiently drying the material that has been fully lifted by the lifting plates 47. The processed material moves to the end under the rotation of the drum 41 and is screened by the filter screen 43 inside the discharge port 42. When the first rotating column 44 rotates, it drives the scraper 45 on it to rotate synchronously, continuously removing the raw material attached to the filter screen 43 to prevent blockage. Finally, the qualified particles are discharged through the discharge port 42.

[0053] When maintenance or replacement of the drying assembly 3 is required, the replacement mechanism 2 is activated. The motor 22, mounted on the side of the base 21, drives the hydraulic rod 23, pushing the base plate 24 along the slide rail 28 on the base 21. The movement of the base plate 24 is transmitted to the telescopic rod 27 via the connecting plate 25 and connecting post 26, causing the telescopic rod 27 to move. This, in turn, drives the clamping plate 51 in the quick-release mechanism 5 to loosen its clamping of the drying assembly 3, allowing maintenance of the drying assembly 3. When the clamping plate 51 needs to be replaced to accommodate different models of the drying assembly 3, the connecting post 52, fixedly connected to the bottom of the clamping plate 51... The baffle 53 interacts with the spring 55 and locking ball 54 located inside the base plate 24. By squeezing or releasing the spring 55, the locking ball 54 is locked or disengaged from the positioning groove of the clamping plate 51, enabling quick disassembly and installation of the clamping plate 51. Throughout the maintenance process, the cover 29 fixed to the top of the outer shell 31 protects the internal structure of the replacement mechanism 2. After maintenance, all components are reset in reverse order, and the equipment can resume operation. Through the synergistic effect of the replacement mechanism 2 and the quick-release mechanism 5, the problems of long maintenance and replacement time and complicated operation of drying components in the prior art are solved.
