Abstract
Description
Technical Field
[0001] This utility model relates to the field of hopper technology, specifically to a hopper for cooling materials. Background Technology
[0002] In the compound fertilizer production process, one of the processing steps is to dry the material from the feed hopper into the dryer. Because the material itself is at a high temperature, it is easy for the hot material to melt when it enters the sealed feed hopper. The melted material will stick to the inner wall of the feed hopper. If the material on the inner wall of the feed hopper is not cleaned in time, the accumulated material will block the feed hopper, making the feed hopper very inconvenient to clean. Therefore, it is necessary to cool the feed hopper in real time.
[0003] In the existing technology, the hopper is cooled by water or air. However, these methods mostly indirectly cool the high-temperature fertilizer by cooling the hopper. In this process, some temperature is lost, resulting in low cooling efficiency. Moreover, the fertilizer temperature is higher near the middle of the hopper and lower near the edge of the hopper, resulting in uneven cooling of the fertilizer. 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] Please see Figure 1-4 This utility model provides a technical solution:
[0022] A material cooling hopper for cooling high-temperature fertilizer includes a discharge port 1, a channel 2, and a feed port 3. The discharge port 1 and the feed port 3 are fixedly connected to both ends of the channel 2, and the feed port 3 is located above the channel 2. The channel 2 is inclined, and a lifting plate 9 is rotatably connected to the inner wall of the channel 2. The lifting plate 9 is in contact with the high-temperature fertilizer, and multiple nozzles 8 are installed at the top of the inner cavity of the channel 2.
[0023] Please see Figure 1 and Figure 2 In this embodiment, nozzle 8 is used to deliver cooling gas to cool the fertilizer. The fertilizer enters the channel 2 from the inlet 3, and after cooling, it is discharged from the outlet 1. Due to the height difference between the outlet 1 and the inlet 3, the fertilizer can move in the inclined channel 2 and can always be in direct contact with the cooling gas delivered by nozzle 8 during the movement, thereby achieving the purpose of cooling the fertilizer. Furthermore, during the conveying of the fertilizer in the channel 2, the lifting plate 9 can reciprocate. Figure 2 As shown, when the right end of the lifting plate 9 contacts the bottom wall of the channel 2, some fertilizer can move to the surface of the lifting plate 9. When the lifting plate 9 starts to rotate, it can lift this part of the fertilizer directly, so that the lifted fertilizer can fully contact the cooling air. At this time, the left side of the lifting plate 9 can contact the bottom wall of the channel 2, thus blocking some of the fertilizer falling along the channel 2 and further extending the contact time between the fertilizer and the cooling gas. Repeating the above process can cool the fertilizer evenly and continuously.
[0024] It should be noted that the nozzle 8 in this embodiment serves to transport cooling gas. Therefore, the actual flow rate of the nozzle 8 should not be too fast to prevent the fertilizer from passing through the channel 2 too quickly under the influence of the cooling gas.
[0025] A second shaft 18 is fixedly installed on the side wall of the lifting plate 9. One end of the second shaft 18 passes through and is rotatably connected to the channel 2. A traction component is connected between one end of the second shaft 18 and the channel 2.
[0026] Please see Figure 2 and Figure 4In this embodiment, the lifting plate 9 is rotatably connected to the side wall of the channel 2 via the second shaft 18. The second shaft 18 can be directly driven to rotate by the traction component, thereby causing the second shaft 18 to drive the lifting plate 9 to rotate. Therefore, the rotation of the lifting plate 9 can be driven in the external environment of the channel 2.
[0027] The traction assembly includes a traction rod 4, a first connecting seat 13, a telescopic rod 14, a second connecting seat 15, and a first shaft 16. The first shaft 16 is fixedly connected to the traction rod 4, the first connecting seat 13 is fixedly connected to the second shaft 18, the second connecting seat 15 is rotatably connected to the first shaft 16, and the telescopic rod 14 is fixedly connected between the first connecting seat 13 and the second connecting seat 15.
[0028] Please see Figure 3 and Figure 4 In this embodiment, the traction rod 4 can perform horizontal reciprocating motion, thus driving the first shaft 16 to move synchronously. For the first shaft 16 and the second shaft 18, when the traction rod 4 moves horizontally, it can drive the second connecting seat 15 to move synchronously. The length of the line connecting the axes of the first shaft 16 and the second shaft 18 will shorten, and the angle between the connecting line and the horizontal direction will also change. Therefore, the second connecting seat 15 can rotate on the first shaft 16. At this time, in order to adapt to the change in the length of the line connecting the axes of the first shaft 16 and the second shaft 18, the second connecting seat 15 will drive the telescopic rod 14 to shorten. At the same time, the second connecting seat 15 can drive the first connecting seat 13 to change its angle through the telescopic rod 14. Since the first connecting seat 13 is fixedly connected to the second shaft 18, the first connecting seat 13 can directly drive the lifting plate 9 to rotate through the second shaft 18. When the traction rod 4 resets, the lifting plate 9 can be rotated in the opposite direction until it is reset through the above process.
[0029] The traction assembly also includes a motor 10, a threaded rod 11, and a drive rod 12. The drive rod 12 is fixedly connected to the traction rod 4. The motor 10 is fixedly installed below the channel 2. The threaded rod 11 is rotatably connected to the channel 2. The output end of the motor 10 is connected to one end of the threaded rod 11. The drive rod 12 is threadedly connected to the threaded rod 11.
[0030] Please see Figure 3 In this embodiment, the reciprocating horizontal movement of the traction rod 4 is achieved by the motor 10, the threaded rod 11, and the drive rod 12. The motor 10 can drive the threaded rod 11 to rotate, and the threaded rod 11 can drive the drive rod 12 to translate axially on its surface, thereby enabling the drive rod 12 to drive the traction rod 4 to move synchronously. By periodically switching the rotation direction of the motor 10 controlled by the frequency converter, the horizontal reciprocating movement of the traction rod 4 can be achieved.
[0031] The traction assembly also includes a spring 17, which is fixedly connected between the first connecting seat 13 and the second connecting seat 15, and is sleeved on the telescopic rod 14.
[0032] Please see Figure 4 For the first connecting seat 13 and the second connecting seat 15, the distance between them needs to change dynamically to adapt to the length change of the line connecting the axes of the first shaft 16 and the second shaft 18. Therefore, in this embodiment, a spring 17 is provided between the first connecting seat 13 and the second connecting seat 15. When the distance between the first connecting seat 13 and the second connecting seat 15 decreases, the telescopic rod 14 shortens and compresses the spring 17, so that the spring 17 stores energy. When the distance between the first connecting seat 13 and the second connecting seat 15 increases, the spring 17 can release energy to assist the telescopic rod 14 in resetting.
[0033] A main pipe 7 is fixedly installed on the inner wall of channel 2. Multiple nozzles 8 are fixedly connected to the main pipe 7 and are inclined. An air inlet pipe 6 is fixedly connected to the main pipe 7. The air inlet pipe 6 passes through channel 2 and extends to the outside.
[0034] Please see Figure 2 In this embodiment, cooling gas is supplied to multiple nozzles 8 through the main pipe 7. The cooling gas inside the main pipe 7 comes from the air inlet pipe 6. Therefore, in actual use, the air inlet pipe 6 needs to be connected to the air supply equipment. The common air supply equipment is an air pump, and the gas used for cooling can be filtered air.
[0035] A stabilizing frame 5 is fixedly connected between the discharge port 1 and the inlet port 3, and the stabilizing frame 5 and the channel 2 form a triangular structure.
[0036] Please see Figure 1 The stabilizing frame 5 can support the discharge port 1, channel 2 and inlet 3 as a whole, so as to increase the overall strength. Furthermore, the stabilizing frame 5 can be used to install the discharge port 1, channel 2 and inlet 3 as a whole near different equipment to facilitate fertilizer feeding.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
