Description

Technical Field

[0001] This utility model belongs to the field of ammonium sulfate production, and in particular relates to an ammonium sulfate filling and unblocking component. Background technology:

[0002] Ammonium sulfate is a colorless crystal or white granule with no odor. It is mainly used in agricultural fertilizers, and industrially in the manufacture of ammonium chloride, ammonium alum, and refractory materials; in rare earth mining, it is used for ion exchange extraction of rare earth elements; and as a dyeing auxiliary, leather deliming agent, or additive in electroplating solutions.

[0003] In the production and packaging process of ammonium sulfate, the finished ammonium sulfate needs to be fed into a packaging machine via a hopper for bagging and shipment. However, in practice, ammonium sulfate is prone to clumping due to environmental factors. This is primarily caused by the hygroscopic nature of ammonium sulfate, leading to deliquescence and recrystallization when ambient humidity is high. Prolonged storage, increased stacking pressure, and temperature fluctuations can also cause clumping, resulting in frequent blockages near the discharge port at the bottom of the hopper. This obstructs the discharge of ammonium sulfate and disrupts the packaging process. Furthermore, external assistance, such as vibrating motors or air hammers, is required to clear the clumping, which shortens the hopper's lifespan. More severe blockages necessitate production shutdowns and manual cleaning, posing a significant potential safety hazard. Summary of the Invention

[0004] The purpose of this invention is to provide an ammonium sulfate filling and unblocking component, which overcomes the shortcomings of the prior art and effectively solves the existing problem of ammonium sulfate clumping and inability to be fed normally.

[0005] The present invention relates to an ammonium sulfate filling and unblocking assembly, comprising a vertically arranged hopper, a first material pipe and a second material pipe horizontally connected to the two side walls at the bottom end of the hopper, a third material pipe coaxially mounted at the outer end of the second material pipe, a drive motor mounted at the outer end of the first material pipe, and a screw conveyor assembly coaxially connected to the drive shaft of the drive motor. The screw conveyor assembly is located in the inner cavity of the first material pipe, the second material pipe and the third material pipe. A discharge pipe is vertically connected downward to the bottom wall at the outer end of the third material pipe. An auxiliary loading assembly is provided at the end of the discharge pipe. The auxiliary loading assembly includes hanging arms. Four hanging arms are evenly installed radially outward on the outer circumferential surface at the bottom end of the discharge pipe. Hooks are installed at the outer ends of the hanging arms. A feeding platform is laid on the working ground directly below the discharge pipe. Guide rails are laid along the length direction at both ends of the top wall of the feeding platform, and a receiving trolley travels on the guide rails.

[0006] Furthermore, guardrails are vertically installed around the top wall of the feeding platform.

[0007] Furthermore, the guide rail is made of angle steel, and the rollers of the receiving trolley are matched with the guide rail.

[0008] Furthermore, a chuck is coaxially mounted on the discharge pipe, the chuck is located below the hanging arm, and the bottom end of the hanging arm is fixedly connected to the top wall of the chuck.

[0009] Furthermore, a boom is connected between the hopper and the third feed pipe.

[0010] The beneficial effects of this utility model are as follows: by setting a filling and unblocking component at the bottom of the hopper, the clumps of ammonium sulfate at the hopper discharge port can be forcibly conveyed out, avoiding blockage and thus restoring the hopper's smooth discharge function, allowing the ammonium sulfate packaging process to proceed normally and orderly.

Detailed Implementation

[0015] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings:

[0016] like Figures 1 to 3 As shown, an ammonium sulfate filling and unblocking assembly includes a vertically arranged hopper 1. A first material pipe 2 and a second material pipe 3 are horizontally connected to the two side walls at the bottom end of the hopper 1. A third material pipe 4 is coaxially installed at the outer end of the second material pipe 3. A drive motor 5 is installed at the outer end of the first material pipe 2. A screw conveyor assembly 6 is coaxially connected to the drive shaft of the drive motor 5. The screw conveyor assembly 6 is located in the inner cavity of the first material pipe 2, the second material pipe 3, and the third material pipe 4. A discharge pipe 7 is vertically connected downward to the bottom wall at the outer end of the third material pipe 4. An auxiliary filling assembly is provided at the end of the discharge pipe 7. A boom 14 is connected between the hopper 1 and the third material pipe 4.

[0017] Specifically, the screw conveyor assembly 6 can force the agglomerated ammonium sulfate at the discharge port of hopper 1 to be conveyed out, thereby restoring the unobstructed discharge function of hopper 1.

[0018] In actual use, when ammonium sulfate in hopper 1 clumps and blocks the bottom discharge port, drive motor 5 can be started and drive screw conveyor assembly 6 to rotate. At this time, the clumped ammonium sulfate is forcibly pushed into the second material pipe 3 by the screw blades in screw conveyor assembly 6. Under the axial thrust of screw conveyor assembly 6, the ammonium sulfate clumps move along the second material pipe 3 and the third material pipe 4. During this movement, the rotating screw blades will also break up the ammonium sulfate clumps. When the ammonium sulfate is pushed to the end of the third material pipe 4, it is discharged downward into the auxiliary loading assembly along the discharge pipe 7. The boom 14 strengthens the connection stability of the third material pipe 4.

[0019] like Figures 1 to 3 As shown, an ammonium sulfate filling and unblocking assembly includes an auxiliary filling assembly comprising hanging arms 8. Four hanging arms 8 are evenly installed radially outward on the outer circumferential surface of the bottom end of the discharge pipe 7. Hooks 9 are installed at the outer ends of the hanging arms 8. A feeding platform 15 is laid on the working ground directly below the discharge pipe 7. Guide rails 10 are laid along the length direction at both ends of the top wall of the feeding platform 15. A receiving trolley 11 travels on the guide rails 10. Guardrails 12 are vertically laid around the top wall of the feeding platform 15. The guide rails 10 are made of angle steel. The rollers of the receiving trolley 11 are matched with the guide rails 10. A chuck 13 is coaxially mounted on the discharge pipe 7. The chuck 13 is located below the hanging arms 8, and the bottom end of the hanging arms 8 is fixedly connected to the top wall of the chuck 13.

[0020] Specifically, the ammonium sulfate delivered by the discharge pipe 7 can be packaged through the auxiliary loading assembly.

[0021] In actual use, the four lifting lugs of the ton bag are attached to the hooks 9 corresponding to the four hanging arms 8, allowing the ton bag to be placed openly and stably on the receiving trolley 11. This allows the ammonium sulfate delivered by the discharge pipe 7 to be directly added into the ton bag. During filling, on-site workers can use sticks to tap the ton bag to break up any remaining clumps of ammonium sulfate. When the ton bag is full, an external winch can be activated to pull the receiving trolley 11 out of the receiving area and transport the ton bag away. The guardrail 12 provides safety protection, and when the outer edge of the receiving trolley 11 contacts the guardrail 12 installed in the width direction of the feeding platform 15, the receiving trolley 11 stops precisely below the discharge pipe 7, thus improving filling efficiency. Using scrap angle steel as the guide rail 10 reduces the cost of auxiliary filling components. The chuck 13 mounted on the discharge pipe 7 provides additional support to the four hanging arms 8, thereby improving the stability of the hanging arms 8.

[0022] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
