Abstract
Description
Technical Field
[0001] This utility model relates to the field of granulation equipment technology, specifically to a large particle nozzle drip receiving device. Background Technology
[0002] A rotary drum granulator is a molding machine that can shape materials into specific shapes. It is one of the key pieces of equipment in the compound fertilizer or granular material industry, suitable for cold and hot granulation as well as large-scale production of high, medium and low concentration compound fertilizers. One working method is as follows: small-diameter urea granules are fed into the rotary drum, and a mist of urea liquid is continuously sprayed inside the drum. Under the rotation of the drum, the drum handle drives the small-diameter granules to roll, so that the outer layer of urea continues to coat them, gradually forming large-diameter urea granules.
[0003] After prolonged operation, the nozzles inside the drum used to spray urea liquid often drip. When the liquid drips onto the inner wall of the drum, it can cause excessive local moisture, which then sticks and condenses on the drum handle, forming urea residue that is difficult to remove. This affects the stable operation of the drum and also the normal forming of material particles.
[0004] In view of the above-mentioned defects, the creator of this utility model has finally obtained this utility model after a long period of research and practice. Utility Model Content

Detailed Implementation
[0023] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.
[0024] Example 1
[0025] like Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 This is a front view of the structure of the large particle nozzle drip receiving device; Figure 2 A top view of the structure of the large particle nozzle drip receiving device; Figure 3 This is a side view of the structure of the large particle nozzle drip receiving device.
[0026] The large particle nozzle drip receiving device of this utility model is used in a rotary drum granulator. The rotary drum granulator includes a rotary drum 1. An infusion pipe 2 for transporting urine is provided inside the rotary drum 1. Several nozzles 3 for spraying urea liquid are provided on the infusion pipe 2 along the extension direction of the infusion pipe 2. Generally, the infusion pipe 2 extends along the axial direction of the rotary drum 1.
[0027] The large-particle nozzle drip receiving device includes a connecting rod 4 and a baffle 5. The two ends of the connecting rod 4 are fixed by a fixing seat 6, and the connecting rod 4 is fixedly installed inside the rotating drum 1. The extension direction of the connecting rod 4 is parallel to the extension direction of the infusion tube 2. The baffle 5 corresponds one-to-one with the nozzle 3 and is installed directly below the corresponding nozzle 3. One side of the baffle 5 is fixedly installed on the connecting rod 4, and the connecting rod 4 can rotate around its own axis.
[0028] Preferably, one end of the connecting rod 4 is provided with a turntable 7, through which the connecting rod 4 can rotate around its own axis, thereby realizing the vibration of the baffle 5 and cleaning the scabs on the baffle 5.
[0029] This invention, by setting a rotatable baffle 5, allows the dripping liquid and small particulate material scale on the nozzle 3 to condense on the baffle 5. By rotating the baffle 5 periodically, the condensed scale blocks are shaken off, thereby reducing the scaling rate of the drum 1 and ensuring the long-term stable operation of the large particle drum 1. At the same time, the height difference between the baffle 5 and the nozzle 3 allows the dripping liquid to splash when it falls on the baffle 5, which also indirectly avoids the accumulation of dripping liquid and reduces the formation of scale.
[0030] Example 2
[0031] like Figure 4 and Figure 5 As shown, Figure 4 This is a front view of the limiting structure on the fixed base; Figure 5 This is a side view of the limiting structure on the fixed seat.
[0032] The two fixed seats 6 are fixedly disposed on the outer sides of both ends of the drum 1. The cross-section of the connecting rod 4 is rectangular, which facilitates the fixing of one edge of the baffle 5 to the connecting rod 4. The two ends of the connecting rod 4 are provided with connecting sections 41. The cross-section of the connecting section 41 is circular. The connecting section 41 is connected to the fixed seat 6 through bearings, which facilitates the free rotation of the connecting rod 4 around its own axis.
[0033] The fixed base 6 is provided with a first limiting post 61 and a second limiting post 62, and the connecting section 41 is provided with a limiting part 42. The limiting part 42 is disposed on the first limiting post 61 and the second limiting post 62. When the connecting rod 4 rotates, the limiting part 42 moves between the first limiting post 61 and the second limiting post 62, thereby limiting the rotation angle of the connecting rod 4.
[0034] Preferably, a rubber layer is provided on the cylindrical surface of both the first limiting post 61 and the second limiting post 62 to prevent damage caused by long-term hard collision between the limiting part 42 and the first limiting post 61 and the second limiting post 62.
[0035] Generally, the limiting part 42 and the baffle 5 are respectively disposed on both sides of the connecting rod 4. The first limiting post 61 is disposed below the limiting part 42, and the second limiting post 62 is disposed above the limiting part 42. When the first limiting post 61 and the limiting part 42 are in contact, and the first limiting post 61 supports the limiting part 42, each of the baffles 5 is in a horizontal state, which facilitates the blocking of the dripping liquid on the nozzle 3 by each of the baffles 5. When the limiting part 42 moves upward and contacts the second limiting post 62, each of the baffles 5 is located below the connecting plate and is inclined, which facilitates the sliding of the scabs on the baffles 5.
[0036] It is worth noting that by rotating the connecting rod 4, the limiting part 42 can collide with the first limiting post 61 or the second limiting post 62, thereby causing each of the baffles 5 to vibrate, which facilitates the sliding off of the scabs on the baffles 5.
[0037] Example 3
[0038] Preferably, the fixing base 6 is provided with a fixing post 63, which is located below the first limiting post 61. The fixing post 63 is connected to the limiting part 42 through an elastic member 8. The elastic member 8 provides elastic tension to make the limiting part 42 fit with the first limiting post 61, thereby ensuring that each of the baffles 5 can be in a stable horizontal state to block the dripping liquid.
[0039] At the same time, by rotating the connecting rod 4 through the turntable 7, the limiting part 42 moves upward and releases the turntable 7 after contacting the second limiting post 62. The limiting part 42 will collide with the first limiting post 61 under the elastic force of the elastic member 8, thereby causing each of the baffles 5 to vibrate, thus facilitating the sliding of the scabs on the baffles 5.
[0040] Specifically, the limiting part 42 includes two fixing plates 421 and a connecting post 422. The two fixing plates 421 are fixedly arranged in parallel on the connecting section 41. The two ends of the connecting post 422 are respectively fixed on the two fixing plates 421, and the axis of the connecting post 422 is parallel to the axis of the connecting rod 4. The connecting post 422 is connected to the end of the elastic member 8 to realize the connection between the elastic member 8 and the limiting part 42.
[0041] Generally, the elastic element 8 is set as a spring, and hooks are provided at both ends of the elastic element 8. The cross-sections of the fixed column 63 and the connecting column 422 are both set as circular. The hooks are respectively hooked on the fixed column 63 and the connecting column 422, so as to facilitate the relative rotation of the hooks with the fixed column 63 and the connecting column 422 when the limiting part 42 moves, and ensure the stability of the elastic tension.
[0042] Preferably, one end of the fixing post 63 is fixedly mounted on the fixing seat 6, and the other end is provided with a limiting ring 631. The hook of the elastic member 8 is disposed between the limiting ring 631 and the fixing seat 6, and the limiting ring 631 prevents the hook from falling off the fixing post 63.
[0043] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
