Description

Technical Field

[0001] The utility model belongs to the technical field of feed drying equipment, and particularly relates to a granular feed drying device. Background Art

[0002] Granular feed is mixed through a predetermined ratio and then sent into a granulator for granulation. The granulated feed still contains moisture. In order to facilitate storage and transportation, it is necessary to dry the granulated feed after granulation.

[0003] The existing granular feed drying device sets a drying box on a section of the path of the granular feed transportation line, so that the conveyor belt passes through the drying box, thereby realizing the automatic feeding of the granular feed into the drying box and the automatic output of the dried granular feed. However, this method cannot turn the granular feed during the drying process, resulting in uneven drying of the side of the granular feed close to the conveyor belt and affecting the drying effect. Secondly, there are also some devices that stagger the conveyor belts from top to bottom in the drying box and turn the granular feed by the way that the granular feed on the upper conveyor belt falls onto the next conveyor belt. After the granular feed falls multiple times, dust will be generated, thus polluting the workshop operation environment. Moreover, the heat in the drying box dissipates quickly, the heat utilization rate is low, and the cost is high. Summary of the Utility Model

[0004] To solve the above deficiencies of the existing technology, the utility model provides a granular feed drying device, which automatically turns the granular feed during the drying process, improves the uniformity of drying of the granular feed, can avoid dusting, improves the workshop environment, and at the same time improves the heat utilization rate and has a low cost.

[0005] To achieve the purpose of the utility model, the following scheme is proposed:

[0006] A granular feed drying device includes:

[0007] A drying box, which is provided with a feed inlet. In the drying box, annular conveyor belts are arrayed with offset edges from top to bottom. One end of the topmost annular conveyor belt is located below the feed inlet. Heating plates are provided on both sides of the drying box. Multiple rows of through holes are arrayed on the heating plates from top to bottom. Each row of through holes corresponds to an annular conveyor belt. One end of the bottom of the drying box is provided with a discharge outlet;

[0008] An air inlet box, which is arranged on one side of the drying box and is used for intermittently blowing air into the drying box;

[0009] An air outlet box, which is arranged on the other side of the drying box. An air outlet hole is provided at the bottom of the air outlet box, and an air outlet pipe is connected to the air outlet hole. The air outlet pipe is wound around the drying box, the air inlet box, and the air outlet box in sequence.

[0010] Further, a feed hopper is provided at the top of the drying box. The feed hopper is arranged corresponding to the feed inlet, and a U-shaped groove is horizontally provided at the connection between the drying box and the feed hopper. A baffle plate is slidably arranged in the U-shaped groove.

[0011] Further, an output belt is provided at the bottom inside the drying box, and one end of the output belt passes out along the discharge port.

[0012] Further, an air inlet is provided at the bottom of one end of the air inlet box, and a blower is connected to the air inlet.

Specific embodiments

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will describe the embodiments of the present utility model in detail with reference to the accompanying drawings. However, the embodiments described herein are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0027] As Figures 1 - 7 shown, this embodiment provides a pellet feed drying device for drying the pellet feed after granulation for easy storage. The device includes: a drying box 10, an air inlet box 20, and an air outlet box 30.

[0028] Specifically, one end of the top of the drying box 10 is provided with a feed inlet 11 for putting the pellet feed after granulation into the drying box 10. Inside the drying box 10, annular conveyor belts 12 are arranged in a staggered array from top to bottom, and all the annular conveyor belts 12 are parallel. One end of the topmost annular conveyor belt 12 is located below the feed inlet 11, so that the annular conveyor belt 12 can convey the put pellet feed from one end of the drying box 10 to the other end. During the conveying process, the put pellet feed can be automatically spread on the annular conveyor belt 12 as the annular conveyor belt 12 moves, so that the pellet feed can be evenly dried. Heating plates 13 are respectively arranged on both sides of the drying box 10 for providing heat sources for drying the pellet feed. The heating plates 13 are arranged in multiple rows of through holes 14 from top to bottom, and each row of through holes 14 corresponds to the conveying surface of an annular conveyor belt 12. This is convenient for discharging the wet and hot air emitted by the pellet feed. One end of the bottom of the drying box 10 is provided with a discharge outlet 15 for discharging the dried pellet feed;

[0029] The air inlet box 20 is arranged on one side of the drying box 10, so that the air inlet box 20 is communicated with the drying box 10 through the through hole 14, so that the air inlet box 20 blows air into the drying box 10 to improve the air flow in the drying box 10, thus facilitating the timely dispersion of the wet and hot air generated by the pellet feed.

[0030] The air outlet box 30 is provided on the other side of the drying box 10. Similarly, the air outlet box 30 is connected through the through hole 14 on the other side of the drying box 10. An air outlet hole 31 is provided at the bottom of the air outlet box 30, and an air outlet pipe 32 is connected to the air outlet hole 31 so that the moisture generated by the granular feed is discharged through the air outlet pipe 32. The air outlet pipe 32 is wound around the drying box 10, the air inlet box 20, and the air outlet box 30 in sequence to reduce the loss of hot air in the drying box 10, so as to improve the utilization rate of the heat source.

[0031] Specific operation method:

[0032] Start the heating function of the heating plates 13 on both sides of the drying box 10 to preheat the drying box 10. At the same time, start the annular conveyor belt 12, and put the granulated granular feed into the drying box 10 along the feed inlet 15. The granular feed falls into one end of the annular conveyor belt 12 on the top layer, and under the action of the annular conveyor belt 12 on the top layer, the put-in granular feed automatically spreads on the annular conveyor belt 12 along the annular conveyor belt 12. When the granular feed moves to the other end of the annular conveyor belt 12 on the top layer, the granular feed automatically falls onto the next layer of the annular conveyor belt 12 and automatically spreads along with the movement of the next layer of the annular conveyor belt 12. During this process, the granular feed is automatically turned over, thus avoiding the situation that only one side of the granular feed is dried, and the drying effect of the side attached to the annular conveyor belt 12 is not good, thereby improving the drying uniformity of the granular feed.

[0033] When the granular feed has been dried for a predetermined time, start the air inlet box 20 to make the air inlet box 20 intermittently blow air into the drying box 10 through the through hole 14, so as to quickly disperse the wet and hot air generated by the granular feed, and make the generated wet and hot air enter the air outlet box 30 through the through hole 14 on the other side of the drying box 10, and then enter the air outlet pipe 32 through the air outlet hole 31 at the bottom of the air outlet box 30, and the wet and hot air is taken out under the action of the air outlet pipe 32. Since the air outlet pipe 32 is wound from bottom to top along the bottom of the air outlet box 30, the drying box 10, and the air inlet box 20 in sequence, the loss of heat in the drying box 10 is reduced. It is inevitable that dust will be generated on the dried granular feed, and the air outlet pipe 32 can be used to reduce the dust during the drying process.

[0034] Preferably, as Figure 2 , Figure 7 shown, the connection between the air outlet pipe 32 and the air outlet box 30 is provided with a detachable connection. Specifically, a lock nut can be used for connection and locking. Each turning point of the air outlet pipe 32 is connected through a bend pipe 321, so as to facilitate the disassembly and cleaning of the air outlet pipe 32.

[0035] Specifically, as Figures 2 - 4As shown in the figure, a feed hopper 16 is provided at the top of the drying box 10. The feed hopper 16 is arranged corresponding to the feed inlet 11. In order to control the flow rate of the granular feed entering the drying box 10 and avoid the situation that when the granular feed after granulation enters the annular conveyor belt 12 in the drying box 10, the flow rate of the granular feed is too large and the thickness of the accumulation on the conveying surface of the annular conveyor belt 12 is too thick, which affects the uniformity of feed drying. A U-shaped groove 17 is horizontally provided at the connection between the drying box 10 and the feed hopper 16. A baffle plate 18 is slidably arranged in the U-shaped groove 17. The flow rate of the granular feed flowing into the drying box 10 is controlled by controlling the length of the baffle plate 18 extending into the U-shaped groove 17.

[0036] Specifically, an output belt 19 is provided at the bottom inside the drying box 10. The output belt 19 is horizontally arranged, and one end of the output belt 19 passes out along the discharge port 15, so as to facilitate the automatic output of the dried granular feed from the drying box 10.

[0037] Specifically, as Figure 6 shown in the figure, an air inlet 21 is provided at the bottom of one end of the air inlet box 20. The air inlet 21 is connected with a blower 22. An installation plate 23 is provided at the bottom of one end of the air inlet box 20. The blower 22 is installed on the installation plate 23. The blower 22 blows air into the air inlet box 20, so that the air entering the air inlet box 20 enters the drying box 10 through the through hole 14, thereby blowing out the wet heat generated by the granular feed and at the same time blowing out the dust generated when the granular feed falls from the upper annular conveyor belt 12 to the lower annular conveyor belt 12 during the drying process of the granular feed, so as to reduce the dust generation during the drying process of the granular feed.

[0038] The above are only the preferred embodiments of the present invention and do not represent the only or limit the present invention. Those skilled in the art should understand that without departing from the scope of the present invention, various changes or equivalent substitutions made to the present invention all belong to the scope of protection of the present invention.
