Description

A scraper device for the production of high-tower fertilizer granules Technical Field

[0001] This utility model relates to the field of compound fertilizer production technology, specifically to a scraper device for the production of high-tower fertilizer granules. Background Technology

[0002] The production of high-tower fertilizer and pesticide granules involves mixing and melting urea, phosphate fertilizer, potash fertilizer, and pesticide powder, then forming granules using high-tower granulation technology. The finished product is obtained through cooling, sieving, and coating processes. The entire process is highly efficient and ensures uniform distribution of nutrients and pesticides.

[0003] Chinese patent discloses a scraping device for the wall of a large granulation tower pot (publication number: CN217829906U). In this device, the scraper is hinged to the scraper frame, allowing the scraper to rotate freely. Furthermore, by using a compression spring, the scraper is pressed tightly against the pot wall surface during scraping, ensuring consistent and efficient scraping. Additionally, because multiple scrapers are used, uneven areas on the pot wall corresponding to one scraper do not affect the scraping effect of other areas. However, this device also has the following drawbacks:

[0004] The aforementioned comparative document describes a scraper device for scraping material from the bottom of a large pot using rotating spiral blades. It also mentions multiple bevel gears that drive the rotation of the spiral blades and the overall revolution of the spiral blades around a rotating axis. However, the bevel gears lack external protective structures and are located close to the bottom of the large pot, making them prone to jamming by material. Therefore, a scraper device for producing high-tower pharmaceutical fertilizer granules is proposed to address these issues. Summary of the Invention

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A scraper device for producing high-tower fertilizer granules includes a high-tower granulation pot, wherein an adjustment mechanism is provided in the middle of the high-tower granulation pot, and the high-tower granulation pot includes a motor one and a motor two.

[0027] As shown in Figures 1-5, a scraper device for producing high-tower granulated pharmaceutical fertilizers includes a high-tower granulation pot 1. An adjustment mechanism 2 is located in the middle of the high-tower granulation pot 1. The high-tower granulation pot 1 includes a motor 108 and a motor 111. The adjustment mechanism 2 includes a lifting block 201. A circular hole is formed in the middle of the inner wall of the lifting block 201. A slider 202 is fixedly connected to the inner wall of the lifting block 201 at one end of the circular hole. Clamping plates 203 are fixedly connected to both sides of the outer wall of the lifting block 201. Each clamping plate 203... The inner side of 03 is rotatably connected to a connecting rod 204. The end of the connecting rod 204 located away from the clamping plate 203 is also rotatably connected to a sliding plate 205. The bottom sides and the middle of the sliding plate 205 are fixedly connected to a pot bottom scraper 206. The top sides of the lifting block 201 are fixedly connected to a spray pipe 207. The spray pipe 207 is L-shaped and has a nozzle on the top side, as shown in Figures 1-2. The sliding plate 205 moves along the lower end of the extension frame 106, and then the pot bottom scraper 206 scrapes the material along the slope of the pot bottom.

[0028] The granulation tower pot 1 also includes a pot wall 101. The side walls and bottom of the pot wall 101 are sloped, and the inner diameter of the pot wall 101 gradually decreases from top to bottom. The bottom of the inner wall of the pot wall 101 is fixedly and continuously connected to a discharge pipe 102. The inner wall of the pot wall 101 is slidably connected to each bottom scraper 206. The middle of the inner side of the discharge pipe 102 is fixedly installed to a motor 111. The output shaft of the motor 111 is fixedly connected to a hollow column 103. The top of the hollow column 103 is rotatably connected to a connecting pipe 104. The bottom sides of the inner wall of the hollow column 103 are connected to conveying hoses 110. The lower ends of the two conveying hoses 110 are respectively connected to the top of the spray pipe 207 and fixedly connected, as shown in Figure 5. The conveying hoses 110 are rubber tubes that can be bent, thereby avoiding obstruction of the lifting block 201 from moving up and down.

[0029] Extension brackets 106 are fixedly connected to both sides of the lower end of the outer wall of the hollow column 103. The lower inner walls of the two extension brackets 106 are slidably connected to the slide plate 205. A pot wall scraper 107 is also fixedly connected to the upper side wall of the extension brackets 106. The bottom of the pot wall scraper 107 is slidably connected to the inner side of the pot wall 101. The lower end of the inner wall of the hollow column 103 is fixedly installed to a motor 108. The output shaft of the motor 108 faces upward and is fixedly connected to a reciprocating screw 109. The top of the device is rotatably connected to the inner wall of the hollow column 103. The outer wall of the hollow column 103 and both sides of the reciprocating screw 109 are provided with lifting grooves 105. The reciprocating screw 109 is connected through to the inner wall of the lifting block 201. The surface thread groove of the reciprocating screw 109 is connected to the slider 202. The inner wall of the lifting groove 105 is slidably connected to the clamping plate 203. As shown in Figure 2, the clamping plate 203 can only move along the length of the lifting groove 105, thereby ensuring the stable lifting of the lifting block 201.

[0030] A sealing ring is fixedly installed on the inner wall of the connecting pipe 104.

[0031] The working principle of this utility model:

[0032] Connect the external water or cleaning agent pipeline to the connecting pipe 104. The fluid can enter the conveying hoses 110 on both sides through the top of the hollow column 103. Finally, the fluid is output through the nozzle of the spray pipe 207. The motor 2 111 can drive the hollow column 103 to rotate continuously, so that the spray pipe 207 can rotate and spray. The pot wall scraper 107 continuously scrapes the material on the side of the pot wall 101.

[0033] Secondly, when the motor 108 starts, it drives the reciprocating screw 109 to rotate continuously. The side of the spiral groove on its surface pushes the slider 202 placed in the lifting block 201 to move axially. When the slider 202 moves to the end of the thread groove, it smoothly reverses direction through the transition curve to achieve reverse motion. The entire process can be completed without changing the rotation direction of the screw, thus completing continuous reciprocating motion. As a result, the nozzle 207 can continuously change its height and spray water or cleaning agent on different areas inside the pot wall 101. When the lifting block 201 moves, it drives the slide plate 205 to slide along the bottom of the extension frame 106 through the connecting rod 204. The pot bottom scraper 206 moves horizontally back and forth, thus continuously hanging material on the bottom of the pot. The pot bottom scraper 206 can also prevent the material falling from the pot wall from adhering to the bottom of the pot. Then the material falls down the slope of the bottom of the pot and is discharged into the discharge pipe 102.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
