Description

Technical Field

[0001] This utility model relates to the technical field of ammonium sulfate production equipment, and in particular to a feeding mechanism for ammonium sulfate production. Background Technology

[0002] As is well known, the continuity and stability of material feeding and conveying are key aspects in the production and processing of ammonium sulfate. Ammonium sulfate has strong hygroscopicity, so its conveying usually requires equipment with good sealing performance. Screw conveying mechanisms have advantages in this regard. To overcome the problem of unstable conveying caused by the high initial pressure and easy compaction of material when a single inclined screw conveyor directly picks up material from the bottom of the silo, ammonium sulfate granules generally adopt a combined feeding mechanism of horizontal screw conveyor and inclined screw conveyor.

[0003] Chinese patent CN222539743U describes a screw feeder's feeding port, which includes a support frame, a funnel body, a speed-regulating motor, and a rotating column. The speed-regulating motor drives the rotating column and agitator to rotate, agitating the internal material and preventing blockages caused by concentrated feeding. However, in actual use, the following problems still exist: However, in a combined feeding mechanism using a horizontal screw conveyor and an inclined screw conveyor, the blades at the interface between the horizontal and inclined screws cannot achieve a seamless connection due to the included angle between their axes. This easily leads to the formation of a static area with extremely poor material flowability at the bottom of the interface. Simultaneously, to accommodate the material characteristics of ammonium sulfate, prevent particles from breaking due to high-speed collisions and generating more hygroscopic fine powder, and control dust, the actual operating speed of the conveying auger is usually limited to a low range. While the lower speed protects the material, it also weakens the effect of the screw blades on the accumulation of material at the bottom of the interface. The combined effect of the material grabbing and cleaning capabilities, the objective existence of static areas, and the process requirements of low-speed operation makes it easy for materials to stagnate and accumulate in these areas. Ammonium sulfate particles stagnate in these static areas, forming dead zones. The particle surfaces absorb moisture and partially dissolve, and then recrystallize under temperature and humidity changes, forming strong crystal bridges. This causes loose materials to harden and clump together. The initial clump layer further hinders the flow of materials, leading to more material accumulating on it and accelerating the formation of clumps under pressure. Ultimately, the clump may completely block the feed inlet of the inclined screw, causing the screw to run idle and even resulting in the loss of feeding capacity.

[0004] Therefore, a feeding mechanism for ammonium sulfate production is proposed. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a feeding mechanism for ammonium sulfate production.

[0006] To achieve the aforementioned objective, this utility model adopts the following technical solution: A feeding mechanism for ammonium sulfate production includes a frame, a hopper fixedly mounted on the frame, a horizontal spiral conveyor assembly fixedly mounted at the bottom of the hopper, and a bidirectional rotary cutting anti-clogging conveyor component on the frame. The bidirectional rotary cutting anti-clogging conveyor component includes a power assembly, a conveying pipe, a main shaft, an auger, a reverse transmission assembly, and an anti-clogging assembly. The discharge end of the horizontal spiral conveyor assembly is connected to the conveying pipe. The power assembly is fixedly mounted on the frame. The conveying pipe is fixedly mounted on the frame. The main shaft is rotatably mounted inside the conveying pipe, with its bottom end passing through the conveying pipe and drivingly connected to the power assembly. The auger is fixedly mounted on the main shaft. The reverse transmission assembly is located below the conveying pipe, with its bottom end drivingly connected to the main shaft. The top end of the reverse transmission assembly passes through the conveying pipe and connects to the lower surface of the anti-clogging assembly. The anti-clogging assembly is located below the discharge end of the horizontal spiral conveyor assembly and is rotatably connected to the inner wall of the conveying pipe. The bottom end of the auger is clearance-fitted with the upper surface of the anti-clogging assembly.

[0007] The reverse transmission assembly includes a housing, a driving bevel gear ring, an idler bevel gear, a driven bevel gear ring, and a transmission tube. The housing is located between the transmission tube and the power assembly. The housing is sleeved on the outside of the main shaft and is fixedly connected to the outer shell of the power assembly. The driving bevel gear ring, the driven bevel gear ring, and the transmission tube are all sleeved on the main shaft. The driving bevel gear ring is fixedly connected to the main shaft. The driven bevel gear ring is located above the driving bevel gear ring and is rotatably connected to the main shaft. The idler bevel gear is rotatably connected to the inner wall of the housing through a short shaft. The idler bevel gear meshes with both the driving bevel gear ring and the driven bevel gear ring. The transmission tube is rotatably connected to the main shaft. The bottom end of the transmission tube is fixedly connected to the upper surface of the driven bevel gear ring. The top end of the transmission tube passes through the housing and the transmission tube in sequence and is fixedly connected to the lower surface of the anti-blocking assembly. The transmission tube is rotatably connected to both the housing and the transmission tube.

[0008] The anti-clogging component includes a rotating ring, a vibrating element, and a rotating auxiliary element. The rotating ring is sleeved on the main shaft and rotatably connected to the main shaft. The lower surface of the rotating ring is fixedly connected to the top end of the transmission tube. The vibrating element is fixedly connected to the lower surface of the rotating ring. The outer edge of the rotating ring is rotatably connected to the inner wall of the transmission tube through the rotating auxiliary element. The bottom end of the auger is clearance-fitted with the upper surface of the rotating ring.

[0009] The rotating auxiliary component includes a bearing and a rubber ring. The inner wall of the transmission pipe is provided with an annular groove. The bearing is located in the annular groove, and the outer ring of the bearing is fixedly connected to the inner wall of the annular groove. The outer edge of the rotating ring is fixedly connected to the inner ring of the bearing through the rubber ring.

[0010] The vibrating component includes an excitation counterweight, and there are several excitation counterweights. The excitation counterweights are fixedly installed on the lower surface of the rotating ring.

[0011] The excitation counterweights are asymmetrically and unevenly distributed circumferentially along the axis of the rotating ring, and are staggered along the radial direction of the rotating ring, with each excitation counterweight having a different mass.

[0012] The transmission pipe is fixedly connected to the frame via a fastener, which includes a fixing ring and an elastic telescopic column. The fixing ring is located above the discharge port of the horizontal spiral transmission assembly and is sleeved on the transmission pipe and fixedly connected to it. One end of the elastic telescopic column is hinged to the frame via a pin, and the other end is hinged to the outer wall of the fixing ring via a pin. A support ring is fixedly installed on the transmission pipe, and a support frame is fixedly installed on the support ring, with the support frame located below the transmission pipe.

[0013] Compared with the prior art, this utility model has the following beneficial effects: Through a reverse transmission mechanism composed of an active bevel gear ring, an idler bevel gear, and a driven bevel gear ring, the rotating ring and the auger conveying the material are driven to rotate in opposite directions, forming a dynamic shear flow field at the bottom of the transmission pipe. This avoids the material from stagnating in the geometric dead zone at the bottom of the pipe for a long time, preventing the material from absorbing moisture and recrystallizing to form stubborn caking. It improves the active scraping and immediate grabbing ability of the material stagnating at the bottom, preventing caking from gradually causing blockage, and improving the stability and anti-blocking ability of the feeder. Furthermore, the vibration generated by the excitation counterweight on the rotating ring keeps the ammonium sulfate material accumulated at the bottom in a continuous active state. The improved material handling process enhances the efficiency of being driven by the reverse shear flow field and grasped by the auger blades, thus strengthening the anti-clogging capability. Simultaneously, the asymmetrical and heterogeneous layout of the excitation counterweight generates wide-frequency excitation in the rotating ring, avoiding the fine powder resonance compaction problem that may occur with traditional single-frequency vibration, further improving the anti-clogging capability. Through a multi-stage vibration isolation system using the elastic coupling of the rubber ring and the damping and filtering of the elastic telescopic column, the strong vibration energy generated by the excitation counterweight is prevented from being disorderly transmitted throughout the entire conveying pipe, thus avoiding a decrease in feeding efficiency. Beneficial vibration energy is confined to the bottom anti-clogging working area, achieving active anti-clogging while ensuring the overall stability of the feeding process.

[0019] like Figure 3 and Figure 7 As shown, the reverse transmission assembly includes a housing 8, a driving bevel gear ring 9, an idler bevel gear 10, a driven bevel gear ring 11, and a transmission tube 12.

The housing 8 is sleeved on the outside of the main shaft 6 and is fixedly connected to the outer shell of the power assembly 4. The driving bevel gear ring 9, the driven bevel gear ring 11, and the transmission tube 12 are all sleeved on the main shaft 6. The driving bevel gear ring 9 is fixedly connected to the main shaft 6. The driven bevel gear ring 11 is located above the driving bevel gear ring 9 and is rotatably connected to the main shaft 6.

The bottom end of the transmission tube 12 is fixedly connected to the upper surface of the driven bevel gear ring 11. The top end of the transmission tube 12 passes through the housing 8 and the transmission tube 5 in sequence and is fixedly connected to the lower surface of the anti-blocking assembly. The transmission tube 12 is rotatably connected to both the housing 8 and the transmission tube 5.

[0020] like Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, the anti-blocking assembly includes a rotating ring 13, a vibrating element, and a rotating auxiliary element. The rotating ring 13 is sleeved on the main shaft 6 and rotatably connected to the main shaft 6. The lower surface of the rotating ring 13 is fixedly connected to the top end of the transmission pipe 12. The vibrating element is fixedly connected to the lower surface of the rotating ring 13. The outer edge of the rotating ring 13 is rotatably connected to the inner wall of the transmission pipe 5 through the rotating auxiliary element. The bottom end of the auger 7 is clearance-fitted with the upper surface of the rotating ring 13.

[0021] like Figure 3 , Figure 4 and Figure 8As shown, the rotating auxiliary component includes a bearing 14 and a rubber ring 15. An annular groove 16 is provided on the inner wall of the transmission pipe 5. The bearing 14 is located in the annular groove 16, and the outer ring of the bearing 14 is fixedly connected to the inner wall of the annular groove 16. The outer edge of the rotating ring 13 is fixedly connected to the inner ring of the bearing 14 through the rubber ring 15.

[0022] like Figure 3 , Figure 4 and Figure 7 As shown, the vibrating component includes an excitation counterweight 17, and there are several excitation counterweights 17. The excitation counterweights 17 are fixedly installed on the lower surface of the rotating ring 13.

[0023] like Figure 4 As shown, the excitation counterweights 17 are asymmetrically and unevenly distributed along the circumferential direction of the axis of the rotating ring 13, and the excitation counterweights 17 are staggered along the radial direction of the rotating ring 13, with each excitation counterweight 17 having a different mass.

[0024] like Figure 1 and Figure 5 As shown, the transmission pipe 5 is fixedly connected to the frame 1 by a fastener. The fastener includes a fixing ring 18 and an elastic telescopic column 19. The fixing ring 18 is located above the discharge port of the horizontal spiral transmission assembly 3 and is sleeved on the transmission pipe 5 and fixedly connected to the transmission pipe 5. One end of the elastic telescopic column 19 is hinged to the frame 1 by a pin, and the other end of the elastic telescopic column 19 is hinged to the outer wall of the fixing ring 18 by a pin. A support ring 20 is fixedly installed on the transmission pipe 5, and a support frame 21 is fixedly installed on the support ring 20. The support frame 21 is located below the transmission pipe 5.

[0025] The work process is as follows: S1. In use, the ammonium sulfate granules to be fed are poured into the hopper 2. At the same time, the horizontal screw conveyor assembly 3 and the power assembly 4 are started. The horizontal screw conveyor assembly 3 quantitatively and stably conveys the ammonium sulfate granules in the hopper 2 to the feed port at the bottom of the inclined conveyor pipe 5. Meanwhile, the power assembly 4 drives the main shaft 6 to rotate. The auger 7 fixed on the main shaft 6 rotates in a direction within the conveyor pipe 5. The rotating blades of the auger 7 grab the material entering through the feed port and lift it upward along the conveyor pipe 5, thereby completing the feeding.

[0026] S2, during the feeding process, the active bevel gear ring 9, fixedly connected to the main shaft 6, rotates together with the main shaft 6. The active bevel gear ring 9 transmits power to the driven bevel gear ring 11 through the idle bevel gear 10 meshing with it. Under the reversing action of the idle bevel gear 10, the driven bevel gear ring 11 obtains a driving force opposite to the rotation direction of the active bevel gear ring 9. This reverse rotational motion drives the rotating ring 13 above to rotate synchronously in reverse through the transmission pipe 12. At this time, the auger 7 rotates in the forward direction to lift the material, while the rotating ring 13 rotates in the reverse direction. The upper surface of the rotating ring 13 maintains a clearance fit with the spiral blade at the bottom of the auger 7. The reverse rotation of the two forms a high-speed dynamic shear flow field in the bottom feeding area of ​​the transmission pipe 5. The rotating ring 13 pushes the material that is trying to stay at the bottom of the pipe. The material is continuously scraped and lifted, and the agitated material is quickly captured and conveyed upward by the forward-rotating auger 7 blades. This process avoids the material from stagnating at the bottom of the pipe for a long time, thus preventing the ammonium sulfate from caking due to moisture absorption and eventually causing blockage. Through the reverse transmission mechanism composed of the active bevel gear ring 9, the idle bevel gear 10 and the driven bevel gear ring 11, the rotating ring 13 and the auger 7 conveying the material are driven to rotate in opposite directions, forming a dynamic shear flow field at the bottom of the transmission pipe 5. This avoids the material from stagnating in the geometric dead zone at the bottom of the pipe for a long time, which would cause the material to absorb moisture and recrystallize to form stubborn caking. This improves the active scraping and immediate grabbing ability of the material stagnating at the bottom, prevents the gradual blockage after caking, and improves the stability and anti-blockage ability of the feeder.

[0027] S3. On the lower surface of the rotating ring 13 facing the bottom of the pipe, multiple excitation counterweights 17 are fixedly installed. These excitation counterweights 17 are asymmetrically and non-uniformly distributed around the axis of the rotating ring 13 and are arranged radially in a staggered manner. The mass of each counterweight is also different. When the rotating ring 13 rotates in the opposite direction with this set of asymmetrical and non-homogeneous excitation counterweights 17, a composite broadband excitation force will be generated. This vibration directly acts on the rotating ring 13 and the material layer above the rotating ring 13. The vibration energy keeps the bottom material particles in a continuous micro-motion state, making the material easier to be driven by the shear flow field and grabbed by the auger 7. Meanwhile, the wide-frequency excitation characteristic avoids energy concentration at a single frequency, thus preventing the problem of fine powder compaction that may result from single-frequency vibration. The vibration generated by the excitation counterweight 17 set on the rotating ring 13 keeps the ammonium sulfate material accumulated at the bottom in a continuous activated state, improving the efficiency of the material being driven by the reverse shear flow field and grasped by the auger 7 blades, and enhancing the anti-clogging capability. At the same time, the asymmetrical and heterogeneous layout of the excitation counterweight 17 enables the rotating ring 13 to generate wide-frequency excitation, avoiding the fine powder resonance compaction problem that may be caused by traditional single-frequency vibration, further improving the anti-clogging capability.

[0028] S4, the outer edge of the rotating ring 13 is connected to the inner ring of the bearing 14 via a rubber ring 15. The outer ring of the bearing 14 is fixed in the annular groove 16 on the inner wall of the transmission pipe 5. The rubber ring 15, as an elastic coupling element, transmits rotational torque while attenuating the direct transmission of high-frequency vibrations generated by the excitation counterweight 17 to the wall of the transmission pipe 5. Simultaneously, the transmission pipe 5 is connected to the frame 1 via a fixed ring 18 and an elastic telescopic column 19. The two ends of the elastic telescopic column 19 are hinged, allowing axial extension and slight oscillation. When residual vibrations not isolated by the rubber ring 15 are transmitted to the transmission pipe 5, the elastic telescopic column 19 further... Absorbing and dissipating vibration energy, effectively preventing vibration from being transmitted upstream along the pipe wall, the support ring 20 and support frame 21 located below the transmission pipe 5 provide the main static support, ultimately localizing the strong vibration precisely to the anti-blocking working area at the bottom of the transmission pipe 5, while ensuring the stability of the feeding operation. Through the multi-stage vibration isolation system of the elastic coupling of the rubber ring 15 and the damping and filtering of the elastic telescopic column 19, the strong vibration energy generated by the excitation counterweight 17 is prevented from being transmitted disorderly to the entire transmission pipe 5, which would lead to a reduction in feeding efficiency. The beneficial vibration energy is confined to the bottom anti-blocking working area, achieving active anti-blocking while ensuring the overall stability of feeding.
