Description

Technical Field

[0001] The utility model relates to the technical field of additive processing, in particular to a drying device for feed additive processing. Background Art

[0002] Feed additives are the raw materials that must be used in the modern feed industry. They have obvious effects on strengthening the nutritional value of basic feed, improving animal production performance, ensuring animal health, saving feed costs, and improving the quality of livestock products. Feed additives need to be stored in a dry and ventilated place. In a humid environment, feed additives tend to condense into lumps. At this time, a drying device is needed to dry the additives.

[0003] The current drying devices for feed additive processing often directly dry the feed additives by hot air. However, in actual use, the damp feed additives will condense into lumps, and direct hot air drying cannot effectively separate the feed additives. In the process of mixing with the feed, the condensed feed additives cannot be evenly mixed with the feed, which greatly affects the actual use effect of the feed additives. Utility Model Content

[0004] Technical problem to be solved: Hot air drying cannot effectively separate feed additives that have condensed into agglomerates.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is: a drying device for processing feed additives, comprising a drying cylinder, an exhaust fan and a heater, a first air duct is provided between the air outlet end of the exhaust fan and the heater, a second air duct is provided between the heater and the drying cylinder, a feed port is provided at the top of the drying cylinder, a screen is provided below the feed port, a working bin is provided below the screen, a first conveying pipe penetrating the wall of the drying cylinder is provided at one end of the screen, a crushing box is provided at the end of the first conveying pipe away from the drying cylinder, crushing wheels are provided on both sides of the crushing box, a second conveying pipe is provided between the bottom of the crushing wheel and the working bin, a discharge port is provided at the middle position of the bottom of the working bin, and a valve is provided at the bottom of the discharge port.

[0006] As an improvement, the screen is tilted and a slope is provided above the screen.

[0007] As an improvement, a second motor is provided on one side of the first conveying pipe, and the driving end of the second motor is connected to a rotating rod that passes through the drying cylinder. The rotating rod is respectively provided with a first rotating wheel and a second rotating wheel, and the first rotating wheel and the second rotating wheel are provided with protrusions.

[0008] As an improvement, a baffle is provided between the crushing wheel and the crushing box body.

[0009] As an improvement, the middle position of the bottom of the working bin is lower than the surrounding areas.

[0010] As an improvement, a shaft rod penetrating the crushing box is respectively provided on one side of the crushing wheel, a first motor and a fixing column are respectively connected to one end of the shaft rod away from the crushing wheel, and gears meshing with each other are respectively provided on the shaft rod.

[0011] As an improvement, a third air duct is connected to the air inlet end of the exhaust fan, a filter box is provided at one end of the third air duct away from the exhaust fan, an air inlet is provided on the side of the filter box, and a plurality of filters are provided inside the filter box.

[0012] The advantages of the utility model compared with the prior art are:

[0013] 1. The screen can filter out the feed additives that have condensed into blocks and transport them to the crushing box. After being crushed by the crushing wheel to form normal granular feed additives, they are transported to the working bin for drying. Normal feed additives directly skip the screen plate and go to the working bin to wait for drying.

[0014] 2. The air inlet end of the exhaust fan is connected to the filter box, which is equipped with multiple filters to filter the air before heating.

[0015] 3. The screen is tilted, there is a slope above the screen, and the middle position of the working bin is lower than the surrounding area. These structures can effectively prevent the accumulation of feed additives. BRIEF DESCRIPTION OF THE DRAWINGS

A working bin 25 is provided below the screen 3. The middle position of the bottom of the working bin 25 is lower than the surrounding area. One end of the screen 3 is provided with a first conveying pipe 5 that passes through the wall of the drying cylinder 1, and one side of the first conveying pipe 5 is provided with a second motor 4. The driving end of the second motor 4 is connected to a rotating rod 26 that passes through the drying cylinder 1, and the rotating rod 26 is respectively provided with a first rotating wheel 27 and a second rotating wheel 28. The first rotating wheel 2 7 and a protrusion 29 are provided on the second rotating wheel 28, a crushing box 15 is provided at the end of the first conveying pipe 5 away from the drying cylinder 1, crushing wheels 6 are respectively provided on both sides of the crushing box 15, a baffle 16 is provided between the crushing wheel 6 and the crushing box 15 body, a shaft 17 penetrating the crushing box 15 is provided on one side of the crushing wheel 6, a first motor 19 and a fixing column 20 are respectively connected to the end of the shaft 17 away from the crushing wheel 6, gears 18 meshing with each other are respectively provided on the shaft 17, a second conveying pipe 7 is provided between the lower part of the crushing wheel 6 and the working bin 25, a discharge port 12 is provided at the middle position of the bottom of the working bin 25, and a valve 13 is provided at the bottom of the discharge port 12.
