Description

Technical Field

[0001] The utility model relates to the technical field of urea production and processing, in particular to a urea storage box for urea preparation. Background Art

[0002] Urea storage tanks for urea preparation are equipment used to safely store raw materials such as ammonia and carbon dioxide required for urea preparation. Their main functions include safe storage of ammonia and carbon dioxide and convenient supply of these raw materials to ensure stability and controllability during urea production. These storage tanks are designed to prevent leakage and other unexpected events, while ensuring the accurate addition of raw materials to the urea synthesis reactor, thereby promoting production efficiency and product quality.

[0003] The traditional way to prepare urea solution is to prepare and store it in an open container. This production method will cause the temperature to drop and crystallize when urea is dissolved in water. At the same time, the ammonia gas produced by the volatilization of the solution is harmful to the human body and poses a safety hazard. The volatilization of the solution will affect the concentration of the solution and thus affect the efficiency of the solution. Therefore, a urea storage box for urea preparation is proposed. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a urea storage box for urea preparation, comprising a box body 1, a box cover 2 is arranged on the upper surface of the box body 1, a motor 3 is fixedly connected to the upper surface of the box cover 2, a rotating shaft 4 is fixedly connected to the output end of the motor 3, a stirring blade 5 is fixedly connected to the outer wall of the rotating shaft 4, a screen 6 is slidably connected to the inside of the box body 1, a protrusion 7 is fixedly connected to one side of the outer wall of the screen 6, a guide rail 8 is arranged inside the box body 1, the outer wall of the protrusion 7 is slidably connected to the inside of the guide rail 8, a handrail 16 is fixedly connected to the outer wall of the box body 1, a sealing strip 9 is fixedly connected to the inside of the box cover 2, the upper surface of the box body 1 is attached to the outer wall of the sealing strip 9, a fixing rod 10 is fixedly connected to the upper surface of the box cover 2, and a fixing component is arranged on the outer wall of the fixing rod 10.

[0023] Specifically, a motor 3 is provided to drive a stirring blade 5 connected to a rotating shaft 4 to stir the solution inside different disposable boxes 1, thereby improving the processing efficiency, avoiding contamination of the solution during packaging, and avoiding uneven concentration, so that the quality of the produced solution is uniform and the concentration is consistent, which can meet production needs.

[0024] Reference Figure 2 and Figure 3 The fixed component includes a connecting block 11, the lower surface of the connecting block 11 is fixedly connected to the upper surface of the fixing rod 10, a slider 12 is fixedly connected to one side of the outer wall of the connecting block 11, a supporting block 13 is provided on one side of the outer wall of the box body 1, a guide rail 14 is provided inside the supporting block 13, the outer wall of the slider 12 is slidably connected inside the guide rail 14, a bottom plate 20 is fixedly connected to one side of the outer wall of the support block 13, a heating block 15 is provided inside the bottom plate 20, the outer wall of the box body 1 is slidably connected inside the heating block 15, a connecting pipe 17 is fixedly connected inside the box body 1, a one-way valve 18 is provided inside the connecting pipe 17, and a switch 19 is provided inside the one-way valve 18.

[0025] Specifically, by arranging handrails 16 and bottom pulleys on the outer wall of the box 1 to facilitate the movement of the box 1, the box 1 can easily enter the interior of the heating block 15, stir and mix at a suitable temperature to improve the quality of the solution, the screen 6 can further help filter impurities to improve the quality of the solution, and the sealed box 1 can prevent the volatilization of the solution from causing concentration changes, thereby providing suitable storage conditions for the solution.

[0026] Working principle: When urea is needed for urea storage, first put the ingredients needed for urea solution into the box 1, and then push the box 1 into the bottom plate 20 by pushing the handrail 16. The outer wall of the box 1 is provided with a pulley to facilitate the movement of the box 1. The heating block 15 inside the bottom plate 20 can heat the box 1 to prevent the solution from crystallizing. Then, the stirring blade 5 connected to the rotating shaft 4 is driven by the motor 3 to rotate, and the liquid inside the box 1 is stirred evenly, so that the urea solution composition is uniform and meets the production requirements. The protrusion 7 connected to the screen 6 slides inside the guide rail 8. After stirring, other fixed impurities inside can be removed. The quality is screened out and cleared, so as to achieve the effect of improving production quality. The slider 12 sliding in the guide rail 14 drives the box cover 2 connected to the connecting block 11 and the stirring mechanism to move out of the box body 1. The worker adds other sealing covers to the box body 1 to store the solution. How to prepare the solution improves production efficiency. There is no need to stir in a fixed container and then store it separately in other containers, which reduces the possibility of solution contamination and achieves the effect of improving production quality. After adding other sealing covers to the box body 1, the solution is stored in the box body 1. The sealed environment can prevent the solution from volatilizing. The volatilization of the solution is likely to cause concentration changes, thereby affecting the solution efficiency.
