Description

Technical Field

[0001] The utility model relates to the technical field of urea filtering, in particular to a high-precision urea filtering device. Background Art

[0002] As a neutral fertilizer, urea is suitable for all kinds of soils and plants. It is easy to store, convenient to use, and has little destructive effect on the soil. It is a chemical nitrogen fertilizer with a large usage and also the nitrogen fertilizer with the highest nitrogen content. In industry, ammonia and carbon dioxide are used to synthesize urea under certain conditions. Urea itself can also be prepared into urea solution. Urea granules are usually dissolved in water during preparation. However, there are large agglomerated urea that is difficult to dissolve or cannot be completely dissolved, which affects the quality of the subsequent urea solution. Therefore, the agglomerated urea granules need to be processed and filtered to improve the production efficiency of the urea solution.

[0003] The existing patent CN215429345U urea filter device adopts a crushing blade to crush the agglomerated granular urea poured into the inner side of the preparation barrel. At the same time, an annular plate and a plurality of rotatably installed knocking columns are arranged above the crushing blade. When the annular plate rotates, the centrifugal force can be used to make the plurality of knocking columns rotate above the inner side of the preparation barrel, and cooperate with the crushing blade to knock and crush the agglomerated granular urea, thereby accelerating the crushing of urea, ensuring that it is well dissolved with water in the later stage, and also facilitating fine filtering work;

[0004] In the above-mentioned comparative documents, since urea particles are of different sizes, the particles of different sizes need to be uniformly crushed before feeding, so as to ensure the subsequent fusion of urea particles and ultrapure water and improve the fusion efficiency. However, the above-mentioned comparative documents adopt the method of crushing in water. Since the crushing in water generates resistance with the liquid during rotation, the urea particles cannot be effectively crushed. Therefore, the utility model proposes a high-precision urea filtering device. Utility Model Content

[0036] 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.

[0037] like Figure 1-6As shown, the utility model provides a technical solution: a high-precision urea filtering device, including a filtering device body 1, the filtering device body 1 includes a mixing assembly 2, the top of the mixing assembly 2 is fixedly connected to a feeding assembly 3, and the feeding assembly 3 is slidably connected to a crushing assembly 4; the crushing assembly 4 includes a crushing box 41, a crushing protection cover 42 is rotatably connected to the crushing box 41, a broken blade 43 is rotatably connected to the inner bottom plate of the crushing protection cover 42, and a waterproof motor 44 is arranged at the bottom of the broken blade 43 on the crushing box 41, and the output of the waterproof motor 44 The end is connected with the broken blade 43, the unloading assembly 3 includes a unloading box 31, a sliding seat 32 is arranged on the top of the unloading box 31, the crushing box 41 is rotatably connected to the sliding seat 32, the unloading box 31 is located in the sliding seat 32 and has a unloading port 34, the mixing assembly 2 includes a mixing box 21, a connecting frame 23 is arranged on the mixing box 21, a rotating shaft 24 is rotatably connected between the connecting frame 23 and the mixing box 21, a stirring plate 27 is arranged on the rotating shaft 24, a supporting frame 22 is arranged at the bottom of the mixing box 21, a driving motor 28 is arranged at the bottom of the mixing box 21, and the driving motor The output end of the mixing box 21 is connected to the rotating shaft 24. The bottom of the mixing box 21 is located between the two driving motors 28 and is fixedly connected to a feeding pipe 29. The urea particles are pre-processed by the crushing assembly 4, and the urea particles put into the crushing box 41 are crushed so that the urea particles of different sizes are crushed into small particles, thereby accelerating the mixing with ultrapure water in the later stage. When the urea particles are crushed, the crushing box 41 is rotated to one side so that the bottom plate of the crushing box 41 is in a closed state, so as to prevent the urea particles from falling from the crushing box 41 during the crushing process. After the urea granules are pre-treated and crushed, the urea granules are introduced into the mixing assembly 2, and the rotating shaft 24 is driven to rotate by the driving motor 28, so that the rotating shaft 24 stirs the urea mixed liquid through the stirring plate 27 during rotation. During the stirring process, under the action of the guide plate 26, the urea mixed liquid forms a vortex, and the two vortices rotating in positive and negative directions collide with each other under the action of the guide plate 25 to form another new vortex. The mixing of urea granules and ultrapure water is accelerated by three vortices, thereby solving the technical problem of low mixing efficiency of urea granules and ultrapure water.

[0038] Further, such as Figure 2 - Figure 5As shown: a guide plate 26 is arranged on the mixing box 21, and the guide plates 26 are distributed in a ring shape, the guide plates 26 on one side are distributed clockwise, and the guide plates 26 on the other side are distributed counterclockwise. The mixing box 21 is provided with a guide plate 25 between the two rotating shafts 24. There are two guide plates 25 in total, and the two guide plates 25 are mirror-symmetrical about the center of the mixing box 21. The two sets of guide plates 26 designed in positive and negative directions can accelerate the formation of two vortices, improve the mixing efficiency of ultrapure water and urea particles, and guide the position where the two vortices contact each other through the guide plate 25. Under the action of the guide plate 25, the flow velocity of the vortex is accelerated, so that it generates greater energy when colliding, so that the fusion of urea particles and ultrapure water when mixed is improved, and the technical problem of uneven mixing of urea mixed liquid is solved.

[0039] The above solution still has the problem that the crushed urea in the feed box 31 cannot enter the mixing box 21. Figure 4 As shown: In the present embodiment, the inner bottom plate of the feed box 31 is provided with a diverter block 35, the diverter block 35 has an inclined structure, and the inclination angle of the diverter block 35 increases from top to bottom. Through the setting of the diverter block 35, the ultrapure water entering the feed box 31 is diverted to both sides under the action of the diverter block 35, and the urea particles attached to the outside of the feed box 31 can be diverted to the inside of the mixing box 21 under the action of the diverter block 35.

Under the action of the diverter block 35, the urea particles attached to the feed box 31 are introduced into the mixing box 21 together, so that they are subsequently mixed with the crushed urea particles.

[0041] Working principle:

[0042] like Figure 1-6As shown, first, the support frame 22 places the filter device body 1 at the specified position, and then the crushing box 41 is rotated to make its bottom in a closed state, and further urea granules are respectively put into the two crushing boxes 41, and the crushing protection cover 42 is closed. At this time, the waterproof motor 44 is turned on to drive the broken blade 43 to crush the urea granules. After crushing, the crushing box 41 is rotated to the specified position, so that the bottom of the crushing box 41 is in an open state. At this time, the urea granules in the crushing box 41 fall into the lower box 31, and at the same time, the ultrapure water is passed through the inlet The water pipe 33 is injected into the discharge box 31. Under the action of the diverter block 35, the urea granules and ultrapure water are introduced into the mixing box 21. The drive motor 28 is turned on to drive the rotating shaft 24 to rotate, so that the rotating shaft 24 stirs the urea mixed liquid through the stirring plate 27 during rotation. During the stirring process, under the action of the guide plate 26, the urea mixed liquid forms a vortex, and the two vortices rotating in the forward and reverse directions collide with each other under the action of the guide plate 25 to form another new vortex. The mixing of urea granules and ultrapure water is accelerated by the three vortices.
