Description

Technical Field

[0001] This utility model relates to the field of urea ammonia dissolving tank technology, specifically to a granular dissolving tank for urea ammonia production. Background Technology

[0002] Urea, also known as carbamide, is a white crystalline solid composed of carbon, nitrogen, oxygen, and hydrogen. It is one of the simplest organic compounds and a major nitrogen-containing end product of protein metabolism in mammals and certain fish. Industrially, urea is used in the ammonia production process. Patent CN202320771590.2 discloses a granular dissolving tank for urea ammonia production. By installing spiral slices and a stirring rack on a rotating shaft, the rotation of the shaft causes the spiral slices to pulverize urea particles in a conical funnel. The pulverized urea flows out through the funnel, and the stirring rack then causes the solution to flow, thereby accelerating the mixing of urea particles and solution and improving the mixing effect of the dissolving tank. However, in the use of this granular dissolving tank for urea ammonia production, the aeration pipe can only aerate the upper part, while the urea precipitate at the bottom of the tank, located around the aeration pipe, is difficult to aerate. Therefore, we propose a granular dissolving tank for urea ammonia production. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a granular dissolving tank for urea to ammonia production.

[0004] The technical solution adopted by this utility model to solve its technical problem is a granular dissolving tank for urea to ammonia production, including a tank body. A base for support is assembled on the inner side of the tank body, and a disc seat for guiding flow is rotatably installed on the top surface of the base. A support cylinder for scraping material is connected to the outer peripheral surface of the disc seat through a flange, and there are multiple sets of support cylinders. The outer peripheral surface of the support cylinder is integrally constructed with a protrusion for scraping material, and the top surface of the disc seat is integrally constructed with a cylinder seat for support. A stirring rod bolted to the cylinder seat is rotatably installed on the inner side of the tank body, and a drive motor for driving the stirring rod to rotate is assembled on the top surface of the tank body.

[0005] The outer circumferential surface of the support cylinder is provided with air holes for aeration, and there are multiple sets of air holes. The bottom surface of the tank is equipped with an aeration pump body by bolts, and a rotary joint for guiding flow is installed between the air inlet end of the disc seat and the tank body. The rotary joint is connected to the air outlet end of the aeration pump body.

[0006] By adopting the above technical solution, during the use of the urea-ammonia granule dissolving tank, the drive motor can operate and drive the stirring rod to rotate, thereby facilitating the stirring of the crushed granules inside the tank. At the same time, the rotation of the stirring rod can drive the plate seat on the top of the chassis to rotate through the cylinder seat, so that the plate seat can drive multiple sets of support cylinders to rotate and the convex strips at the bottom of the support cylinders can scrape the sediment at the bottom of the tank, so that the sediment can be lifted and moved for easy dissolution, thereby further improving the efficiency of urea granule dissolution.

[0007] When the disc base rotates, it enables the aeration pump at the bottom of the tank to operate and facilitates aeration through the airflow holes inside the disc base via the rotary joint. This allows the gas to pass through the channels inside the disc base and easily enter the support cylinder, thus facilitating its discharge from the multiple sets of air holes on the outer periphery of the support cylinder and aerating the inside of the tank. This improves the dissolution efficiency of urea particles. At the same time, the support cylinder can rotate to scrape the sediment with the convex strips, allowing it to move, and it can also vent air, facilitating aeration of the solution and urea inside the tank, further improving the urea dissolution effect and reducing the impact of aeration in a fixed position.

[0008] Specifically, a check valve is installed at the connection between the rotary joint and the disc base.

[0009] By adopting the above technical solution, the check valve can reduce the situation where the solution flows back into the outlet of the aeration pump body when it enters the support cylinder.

[0010] Specifically, the outer peripheral surface of the tank is fitted with a glass plate for observation.

[0011] By adopting the above technical solution, the glass plate makes it convenient for personnel to observe the dissolution status of urea inside the tank.

[0012] Specifically, a leak-proof rubber ring is bonded to one end of the support cylinder near the plate seat, and a rubber strip for assisting in scraping material is provided on the outer periphery of the protrusion.

[0013] By adopting the above technical solution, the rubber ring can improve the tightness of the connection between the support cylinder and the plate seat, while the rubber strip has good elasticity, which can improve the effect of the convex strip on scraping the sediment inside the tank.

[0014] Specifically, a nozzle is screwed onto the inner side of the air hole.

[0015] By adopting the above technical solution, the nozzles screwed into the air holes facilitate the discharge of gas during aeration, allowing the gas to be discharged into the tank in a convenient and stable manner, which is convenient for assisting in the dissolution of urea.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of a drive motor, stirring rod, chassis, disc base, cylinder base, support cylinder, and convex strips, enables the drive motor to operate and drive the stirring rod to rotate during the use of the urea-to-ammonia granule dissolving tank. This facilitates the stirring of the crushed granules inside the tank by using the stirring rod. At the same time, the rotation of the stirring rod facilitates the rotation of the disc base on the top of the chassis through the cylinder base. This allows the disc base to drive the rotation of multiple sets of support cylinders, and the convex strips at the bottom of the support cylinders can scrape the sediment at the bottom of the tank, causing the sediment to be lifted and moved for easy dissolution, thereby further improving the efficiency of urea granule dissolution.

[0018] 2. The technical solution of this application, through the design of the aeration pump body, rotary joint, and air holes, enables the aeration pump body at the bottom of the tank to operate when the disc base drives the support cylinder to rotate. This allows the pump to easily blow air through the airflow holes inside the disc base via the rotary joint, enabling the gas to pass through the internal channels of the disc base and easily enter the support cylinder. This facilitates the gas to be discharged from the multiple sets of air holes on the outer periphery of the support cylinder, thus facilitating aeration inside the tank and improving the dissolution efficiency of urea particles. At the same time, the support cylinder can rotate to scrape the sediment with the convex strip, allowing it to move, and it can also vent air, facilitating aeration of the solution and urea inside the tank, further improving the urea dissolution effect and reducing the impact of aeration in a fixed position.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1-3This utility model provides a technical solution: a granular dissolving tank for urea to ammonia production, comprising a tank body 1, a base 2 for support mounted inside the tank body 1, a disc seat 3 for flow guidance rotatably mounted on the top surface of the base 2, a support cylinder 4 for scraping material connected to the outer periphery of the disc seat 3 via a flange, and multiple sets of support cylinders 4, a protrusion 5 for scraping material integrally constructed on the outer periphery of the support cylinder 4, and a cylinder seat 6 for support integrally constructed on the top surface of the disc seat 3, and a stirring rod 8 bolted to the cylinder seat 6 rotatably mounted inside the tank body 1, a drive motor 7 for rotating the stirring rod 8 is mounted on the top surface of the tank body 1; air holes 11 for aeration are opened on the outer periphery of the support cylinder 4, and multiple sets of air holes 11 are provided; an aeration pump body 9 is bolted to the bottom surface of the tank body 1, and a rotary joint 10 for flow guidance is mounted between the air inlet end of the disc seat 3 and the tank body 1, the rotary joint 10 being connected to the air outlet end of the aeration pump body 9.

[0026] During use, when using the urea-ammonia granule dissolving tank, the drive motor 7 can operate and drive the stirring rod 8 to rotate, so that the stirring rod 8 can be used to stir the crushed granules inside the tank 1. At the same time, the rotation of the stirring rod 8 can drive the plate seat 3 on the top of the base 2 to rotate through the cylinder seat 6, so that the plate seat 3 can drive multiple sets of support cylinders 4 to rotate, and the protrusions 5 at the bottom of the support cylinders 4 can scrape the sediment at the bottom of the tank 1, so that the sediment can be lifted and moved to facilitate dissolution, thereby further improving the efficiency of urea granule dissolution.

[0027] When the disc base 3 drives the support cylinder 4 to rotate, the aeration pump 9 at the bottom of the tank 1 can operate and easily blow air through the airflow holes inside the disc base 3 via the rotary joint 10. This allows the gas to pass through the channels inside the disc base 3 and easily enter the support cylinder 4, thus facilitating its discharge from the multiple sets of air holes 11 on the outer periphery of the support cylinder 4 and facilitating aeration inside the tank 1. This improves the dissolution efficiency of urea particles. At the same time, the support cylinder 4 can rotate to drive the convex strip 5 to scrape the sediment, making it movable, and it can also vent air, facilitating aeration of the solution and urea inside the tank 1, further improving the dissolution effect of urea, and reducing the impact of aeration in a fixed position.

[0028] like Figure 2 As shown, a check valve 14 is installed at the connection between the rotary joint 10 and the base 3.

[0029] When in use, the check valve 14 helps to reduce the backflow of solution into the outlet of the aeration pump body 9 when the solution enters the support cylinder 4.

[0030] like Figure 1 As shown, a glass plate 15 for observation is fitted on the outer circumferential surface of the tank body 1.

[0031] During use, the glass plate 15 allows personnel to easily observe the dissolution status of urea inside the tank 1.

[0032] like Figure 2 and Figure 3 As shown, a rubber ring 16 for preventing leakage is glued to one end of the support cylinder 4 near the plate seat 3, and a rubber strip 13 for assisting in scraping material is provided on the outer periphery of the protrusion 5.

[0033] When in use, the rubber ring 16 helps to improve the tightness of the connection between the support cylinder 4 and the plate seat 3, while the rubber strip 13 has good elasticity, which helps to improve the effect of the convex strip 5 in scraping the sediment inside the tank 1.

[0034] like Figure 3 As shown, a nozzle 12 is screwed onto the inner side of the air hole 11.

[0035] During use, the nozzle 12 screwed into the air hole 11 facilitates the discharge of gas during aeration, allowing the gas to be discharged into the tank 1 in a convenient and stable manner, which is helpful for dissolving urea.

[0036] The working principle and usage process of this utility model are as follows: In use, first, install the corresponding structural components in suitable positions. During the use of the urea-ammonia granule dissolving tank, add the urea raw material and the dissolving solution into the tank 1 through the corresponding channels. Then, the drive motor 7 operates and drives the stirring rod 8 to rotate, facilitating the stirring of the pulverized urea granules inside the tank 1. Simultaneously, the rotation of the stirring rod 8 facilitates the rotation of the disc base 3 on top of the base 2 via the cylinder seat 6. This allows the disc base 3 to drive the rotation of multiple sets of support cylinders 4, and the protrusions 5 at the bottom of the support cylinders 4 can scrape the sediment at the bottom of the tank 1, causing the sediment to rise and move for easier dissolution, thereby further improving the efficiency of urea granule dissolution. Furthermore, the disc base 3 drives... When the support cylinder 4 rotates, it enables the aeration pump 9 at the bottom of the tank 1 to operate and facilitates aeration through the airflow holes inside the disc seat 3 via the rotary joint 10. This allows the gas to pass through the channels inside the disc seat 3 and easily enter the support cylinder 4, thus facilitating its discharge from the nozzles 12 in the multiple sets of air holes 11 on the outer periphery of the support cylinder 4. This facilitates aeration inside the tank 1, thereby improving the dissolution efficiency of urea particles. At the same time, the support cylinder 4 can rotate to drive the convex strip 5 to scrape the sediment, allowing it to move, and it can also vent air, facilitating aeration of the solution and urea inside the tank 1. This further improves the urea dissolution effect and reduces the impact of aeration in a fixed position, enabling the dissolution equipment to dissolve urea particles more stably and facilitating subsequent ammonia production.
