Description

Technical Field

[0001] This utility model relates to the field of ammonia gas feed control technology, specifically to an intelligent ammonia gas feed control mechanism for a compound fertilizer granulator. Background Technology

[0002] Intelligent ammonia feed control in compound fertilizer granulators is a key aspect of ensuring product quality and production efficiency. It achieves precise regulation primarily through the linkage of a flow meter and regulating valve. A mass flow meter monitors the ammonia flow rate in real time, and a PID algorithm dynamically adjusts the opening of the sealing components to maintain a stable feed. Simultaneously, an online pH sensor monitors the acidity or alkalinity of the material, automatically adjusting the ammonia flow rate to ensure sufficient chemical reaction and prevent excessive acidity or alkalinity. Furthermore, the system incorporates a pressure compensation mechanism, automatically correcting the ammonia flow rate based on internal pressure fluctuations in the reaction tank to prevent process deviations. To optimize control, the system integrates multiple parameters such as temperature and humidity for coordinated adjustment, improving granulation uniformity. A flow rate limit and emergency shut-off device ensure safe production, ultimately achieving compound fertilizer production with high granule strength and uniform nutrient distribution, while reducing energy consumption and raw material waste.

[0003] The existing intelligent ammonia feed control device has the problem of not being able to accurately control the amount of ammonia in actual use, which seriously affects the granulation quality. When the amount of ammonia is too much, it will cause the granulated material to react too violently, resulting in a loose particle structure and reduced strength. This makes the particles easy to break during subsequent storage and transportation, affecting the integrity of the product and its market value. Therefore, we need an intelligent ammonia feed control mechanism for compound fertilizer granulators. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model embodiment provides an intelligent ammonia feed control mechanism for a compound fertilizer granulator, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the system includes a support frame 1, a reaction vessel 2 fixedly connected inside the support frame 1, a first feed pipe 3 fixedly connected to the outer wall of the reaction vessel 2, a second feed pipe 4 fixedly connected to the outer wall of the reaction vessel 2, a discharge pipe 6 fixedly connected to the outer wall of the reaction vessel 2, a sealing assembly 5 fixedly connected to the outer wall of the second feed pipe 4, a control assembly 7 provided on the outer wall of the sealing assembly 5, the sealing assembly 5 including a connecting plate 501, and the connecting plate 501 is installed on the outer wall of the second feed pipe 4, a valve body 502 fixedly connected to one side of the connecting plate 501, and a control assembly 7 fixedly connected to the inner wall of the valve body 502. A baffle 503 is provided, and a groove 504 is provided on one side of the baffle 503. A sealing strip 505 is fixedly connected to the inner wall of the groove 504. A movable column 506 is movably installed on the inner wall of the valve body 502. A valve core 507 is fixedly connected to the outer wall of the movable column 506. A protrusion 508 is fixedly connected to one side of the valve core 507. A sealing flange 509 is fixedly connected to one side of the protrusion 508. The protrusion 508 drives the sealing flange 509 to rotate, so that the sealing flange 509 and the sealing strip 505 can be sealed, thereby closing the sealing assembly 5 to prevent the entry of ammonia gas.

[0022] Furthermore, such as Figure 2 As shown, the connecting plate 501 forms a fixed structure with the valve body 502 and the baffle 503. The outer wall of the valve body 502 is fixed with the inner wall of the connecting plate 501, and the inner wall of the valve body 502 is fixed with one side of the baffle 503. The valve body 502 strengthens the fixing effect between the valve body 502 and the baffle 503 and improves the stability of fixing the baffle 503.

[0023] Furthermore, such as Figure 2 and Figure 4 As shown, the baffle 503 forms a sealing structure with the protrusion 508 through the groove 504, and the inner diameter of the groove 504 matches the outer diameter of the protrusion 508. The inner wall of the groove 504 fits against the outer wall of the protrusion 508. Through the groove 504, when the baffle 503 and the protrusion 508 are sealed, the protrusion 508 can be inserted into the groove 504 for sealing installation, which enhances the sealing effect of the baffle 503.

[0024] Furthermore, such as Figure 2 and Figure 4 The baffle 503 shown forms a sealing structure with the sealing strip 505 and the sealing flange 509. The inner diameter of the sealing strip 505 matches the outer diameter of the sealing flange 509, and the inner wall of the sealing strip 505 fits against the outer wall of the sealing flange 509. With the sealing strip 505, the sealing strip 505 can seal the sealing flange 509 by relying on the groove 504 for fixation, thereby improving the sealing effect of the baffle 503.

[0025] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 The control assembly 7 shown includes a fixed housing 701, which is mounted on the outer wall of the movable column 506. A housing 702 is fixedly connected to the outer wall of the fixed housing 701. A motor 703 is fixedly connected to one side of the housing 702. The output shaft of the motor 703 is fixedly connected to a worm gear 704 via a coupling. A throttle 705 is fixedly connected to one end of the worm gear 704. A worm wheel 706 is meshed with the outer wall of the worm gear 704. The sealing flange 509 is rotated by the protrusion 508, which allows the sealing flange 509 to engage with the sealing strip 506. 5. Seal the container to prevent ammonia from entering. By starting the motor 703, the motor 703 drives the worm gear 704 to rotate, which in turn drives the worm wheel 706 to rotate. The worm wheel 706 then drives the movable column 506 to rotate, which in turn drives the valve core 507 to rotate. The valve core 507 then drives the protrusion 508 to rotate, thereby controlling the amount of ammonia entering. The worm gear 704 can also be manually controlled by the throttle 705.

[0026] Furthermore, such as Figure 2 As shown, the chassis 702 forms a rotating structure with the worm gear 704 and the throttle 705. One end of the throttle 705 passes through the chassis 702 and the worm gear 704 and is fixed therethrough. With the throttle 705, the worm gear 704 can be rotated under the support of the chassis 702.

[0027] Furthermore, such as Figure 3 As shown, the motor 703 forms a rotating structure through the worm 704 and the worm wheel 706. One end of the worm 704 is fixed to the output end of the motor 703, and the outer diameter of the worm 704 matches the outer diameter of the worm wheel 706. The outer wall of the worm 704 meshes with the outer wall of the worm wheel 706. Through the worm 704, the worm 704 can drive the worm wheel 706 to rotate under the drive of the motor 703.

[0028] Working Principle: During operation, sulfuric acid is fed through the first feed pipe 3, and gaseous ammonia is fed through the second feed pipe 4. The sulfuric acid and gaseous ammonia react inside the granulator. Starting the motor 703 drives the worm gear 704, which in turn drives the worm wheel 706. The worm wheel 706 then drives the movable column 506, which in turn drives the valve core 507. This valve core 507 controls the gas flow, thus completing the process of... The amount of ammonia entering can be controlled manually by the throttle 705 driving the worm gear 704. When it is necessary to close the sealing assembly 5, the protrusion 508 can drive the sealing flange 509 to rotate, allowing the protrusion 508 to extend into the groove 504 for sealing, and the sealing flange 509 to seal with the sealing strip 505, thereby closing the sealing assembly 5 to prevent the entry of ammonia. This allows sulfuric acid and ammonia to react inside the granulator, and the resulting ammonium sulfate solution can be output through the discharge pipe 6 after the reaction is completed.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
