Description

Technical Field

[0001] The invention relates to the technical field of drying devices, and in particular to a livestock breeding feed drying device. Background Art

[0002] During the drying process of the dryer, the hot air flows forward from the tail, fully contacts the material, and directly transfers the heat energy to the material, so that the moisture of the material is continuously evaporated in the cylinder.

[0003] For example, a Chinese patent with authorization announcement number CN109163530B provides a livestock feed drying device, including an air energy heat pump and a dehumidifier connected in series by a heating pipe. The device can lift the dried and mixed biological feed, increase the contact area between the hot air flow and the biological feed, and achieve sufficient drying of the biological feed. When the humidity sensor detects that the humidity of the material in the dryer reaches the standard set humidity value of the biological feed, the relay controls the switch circuit driven by the humidity sensor to open the electric valve at the discharge pipe, and the dried biological feed is unloaded and packaged.

[0004] The dryers in the prior art are mostly of two types: drum type and pressure tank type. Although they can dry the feed, the drying process is uneven. Feeds of different sizes have different moisture contents, so the drying and dehydration degree of larger particles and smaller particles will be different, which will lead to uneven feed processing quality.

When the second discharging assembly is in the second state, the second discharging port 293 and the first discharging port 252 are both closed, and when one second discharging assembly is in the first state, the other second discharging assembly is in the second state. The two second discharging assemblies can be in the second state at the same time, that is, when one second discharging assembly is in the second state, the other second discharging assembly is in the first state or the second state.

[0038] In this embodiment, if Figure 2 As shown, a livestock feed drying device also includes a control box 221, which is fixedly arranged on the drying cylinder 220. The control box 221 controls the large telescopic cylinder 291 and the small telescopic cylinder 271 to extend and retract the first telescopic rod and the second telescopic rod.

[0040] In this embodiment, the material receiving member 260 is elastic, and the fixed connection between the material receiving member 260 and the rotating drum 250 can be bent. When the material receiving member 260 is in the first position after being retracted upward, part of the material receiving member 260 overlaps. When the material receiving member 260 is in the first position, the radius of the opening end of the material receiving member 260 is the smallest, and when the material receiving member 260 is in the second position, the radius of the opening end of the material receiving member 260 is the largest.

[0041] In this embodiment, if Figure 5 As shown, a first through hole is provided on the drying cylinder 220, and the screening and drying mechanism further includes a material shifting assembly, which includes a first small motor 280 and a material shifting rod 281.

[0043] In this embodiment, a livestock feed drying device further includes a discharge cylinder 223, which is fixedly arranged on the lower end surface of the drying cylinder 220, and the discharge cylinder 223 is connected with the rotating cylinder 250. When the first discharge port 252 and the second discharge port 293 corresponding to the material receiving member 260 are connected, the material on the material receiving member 260 enters the material blocking cylinder 292 from the first discharge port 252 and the second discharge port 293, and then falls from the material blocking cylinder 292 into the discharge cylinder 223, and then is discharged from the drying cylinder 220.

[0044] Two air outlet pipes 225 are provided on the peripheral wall of the drying drum 220. The air outlet pipes 225 are connected to the drying drum 220. One air outlet pipe 225 is located between the two material receiving members 260, and the other air outlet pipe 225 is located at the lower side of the material receiving member 260 located at the lower side. A one-way valve is provided in each air outlet pipe 225, and the one-way valve allows the gas in the drying drum 220 to flow to the outside.

[0045] In this embodiment, if Figure 1 As shown, a livestock breeding feed drying device further includes a feeder 200, and the feeder 200 is used to convey materials to two feed barrels 222. The feeder 200 conveys materials to the two feed barrels 222 at intervals.

[0046] Working process: A livestock feed drying device includes a screening stage and a drying stage.

[0047] Screening stage: Start the large motor 240, which drives the drum 250 to rotate, and the rotation of the drum 250 drives the screen plate assembly 251 to rotate. The feeder 200 first delivers the material into the feed drum 222 in one of the discharge mechanisms. In the initial state, the material receiving member 260 is in the first position, and its opening end has the smallest radius. The material receiving member 260 is combined with the screen plate assembly 251, that is, the peripheral wall of the material receiving member 260 is against the peripheral walls of the first screen plate, the second screen plate and the baffle.

[0048] The material first comes to the first sieve plate from the feed barrel 222. The material that does not conform to the first sieve hole is temporarily stored in the space formed by the first sieve plate and the material receiving member 260. The material that conforms to the first sieve hole passes through the first sieve hole and comes to the space formed by the second sieve plate and the material receiving member 260. The material that does not conform to the second sieve hole is temporarily stored in the space formed by the second sieve plate and the material receiving member 260. The material that conforms to the second sieve hole passes through the second sieve hole and comes to the space formed by the baffle plate and the material receiving member 260. After the screening is completed, materials of different sizes are placed in different spaces.

[0049] Drying stage: After the screening is completed, the control box 221 controls the small telescopic cylinder 271 to extend the first telescopic rod, drive the sliding member 270 to move upward, and then drive the material receiving member 260 to expand to the second position through the hinge rod 272. At this time, the material receiving member 260 is still conical. The material falls from the space formed by the sieve plate assembly 251 and the material receiving member 260 onto the material receiving member 260. The radial distribution of materials of different sizes on the material receiving member 260 is: from the inside to the outside, the material thickness becomes thinner and thinner. Then the material is flattened by the material lever 281. Since the material receiving member 260 is conical, after the material is flattened above, the closer the material is to the center of the material receiving member 260, the thicker it is, so that the moisture content of the material at each location on the material receiving member 260 is the same. At the same time, the material turning lever 282 turns the material so that the material is heated evenly.

[0050] At the same time, the blower 100 is started, and the hot air flows from the air inlet 230 to the multiple branch pipes 231, and then to the drying cylinder 220. After the hot air contacts the material receiving member 260, the material receiving member 260 is heated, and the material in the material receiving member 260 is dried by heat transfer. The water vapor generated after the material is dried is discharged from the air outlet 224. The hot air is discharged outward through the air outlet pipe 225. After the material on the material receiving member 260 is dried, the first small motor 280 and the second small motor 283 are started first, and the material shifting rod 281 and the material turning rod 282 are driven to rotate upward respectively. Then the small telescopic cylinder 271 is controlled by the control box 221, so that the first telescopic rod is contracted, driving the sliding member 270 to move downward, and then the material receiving member 260 is driven to contract to the minimum radius through the hinged rod 272, and then comes to the first position again.

[0051] While the first telescopic rod gradually contracts, the large telescopic cylinder 291 is controlled by the control box 221 to cause the second telescopic rod to contract. The second telescopic rod drives the material blocking barrel 292 to move upward, connecting the first discharge port 252 and the second discharge port 293 corresponding to the material receiving member 260. The material on the material receiving member 260 enters the material blocking barrel 292 from the first discharge port 252 and the second discharge port 293, and then falls from the material blocking barrel 292 into the discharge barrel 223, and is then discharged from the drying barrel 220.

[0052] When the material receiving member 260 of one screening and drying mechanism is in the first position and the material is screened on the screen plate assembly 251, the material receiving member 260 of the other screening and drying mechanism is in the second position and the material is dried on the material receiving member 260. The two screening and drying mechanisms operate alternately to ensure the continuity of the operation of the device.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
