Description

Technical Field

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

[0002] Feed is a general term for food for animals raised by all people. In a narrower sense, general feed mainly refers to the food for animals raised in agriculture or animal husbandry. Feed (including soybean, soybean meal, corn, fish meal, amino acid, miscellaneous meal, whey powder, oil, meat and bone meal, grains, feed additives and more than ten varieties of feed raw materials. In the production process of pelletized animal feed, in order to make the pelletized animal feed able to be stored for a long time and easy to transport, it is often necessary to dry the pelletized animal feed, and a drying device is often used during the drying process.

[0003] In the prior art, when drying pellet feed, feed pellets with a high moisture content in the early stage are prone to adhere to the inner wall of the device. After drying in the later stage, part of the feed is dehydrated so that it adheres more tightly to the inner wall of the device. However, common drying equipment does not have the effect of cleaning the inner wall. In order not to affect the subsequent drying, the inner wall of the device needs to be cleaned after each drying, which increases the maintenance cost. How to invent a pellet feed drying device to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a pellet feed drying device, which aims to improve the problem that common drying equipment does not have the effect of cleaning the inner wall, resulting in increased maintenance costs.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a pellet feed drying device, comprising a device body and a stirring roller arranged on the device body, wherein a feeding port is provided at the upper end of the device body, a feeding port is provided at the bottom end of the device body, a motor is installed on one side outer wall of the device body, a mounting seat is fixedly connected to the outer wall of the device body, an air pump and a heating device are respectively installed on the mounting seat, and a plug board is plugged into the inner wall of the device body;

[0007] Both ends of the stirring roller are rotatably connected to the inner wall of the device body, an air cavity is opened at one end of the stirring roller, the inner wall of the air cavity is rotatably connected to an air pipe connected to an air pump, a plurality of air holes are opened on the inner wall of the air cavity, a plurality of stirring blades are fixedly connected to the outer wall of the stirring roller, a slide groove is opened at one end of the stirring blade, a plurality of springs are fixedly connected to the inner wall of the slide groove, one end of the spring is fixedly connected to a scraper slidably connected to the inner wall of the slide groove, and rollers are rotatably connected to the outer walls of both ends of the scraper.

[0008] Preferably, the upper end of the drying chamber inside the device body is a rectangular trough and the lower end is a semicircular trough, the air outlet end of the heating device and the air inlet end of the air pump are connected by a pipe, the output end of the motor and one end of the stirring roller are fixedly connected, and the outer wall of the roller is closer to the inner wall of the drying chamber of the device body than the scraper.

[0009] By adopting the above technical solution, the feed is put into the device body through the feeding port, and the motor, the heating device and the air pump are started to allow hot air to pass into the device body through the air holes of the stirring roller, and the feed is stirred by the rotation of the stirring blades, so that the feed particles can be fully exposed to the air for drying. During the rotation, the roller abuts against the semicircular inner wall of the device body, so that the scraper scrapes off the material adhered to the inner wall of the drying chamber, and then the plug plate is pulled out to allow the feed to fall through the feeding port for collection.

[0010] Preferably, a connecting groove is provided on the inner wall of the stirring roller close to the stirring blade, and a plurality of air inlet grooves are provided on the inner wall of the connecting groove.

[0011] Preferably, a sealing groove is provided at one end of the air inlet groove, a fixing sleeve is fixedly connected to one end of the sealing groove close to the air inlet groove, and a first air outlet is provided at the upper end of the fixing sleeve.

[0012] Preferably, a second air outlet is formed at the upper end of the sealing groove near the first air outlet, a plurality of the second air outlets are provided at the upper ends of interconnected inflation grooves, a plurality of air ducts are formed at one end of the inflation groove, and an air nozzle is installed on the inner wall of one end of the air duct.

[0013] Preferably, one end of the scraper is fixedly connected to a fixing rod slidably connected to the inner wall of the sealing groove, and one end of the fixing rod is fixedly connected to a sealing sleeve slidably connected to the inner wall of the sealing groove.

[0014] Preferably, the inner wall of the sealing sleeve and the outer wall of the fixing sleeve are slidably connected, a third air outlet is provided on the inner wall of the sealing sleeve close to the first air outlet, and the first air outlet, the second air outlet and the third air outlet are of the same size.

[0015] By adopting the above technical solution, when the roller and the inner wall of the device body are squeezed and rotated, the scraper drives the sealing sleeve on the fixed rod at one end to slide, so that the third air outlet hole opened on the sealing sleeve and the first air outlet hole and the second air outlet hole on the inner and outer sides are aligned. At this time, high-pressure hot air enters the inflation groove through multiple air outlet holes, and the air is discharged toward the inner wall of the device body through the air nozzle, so that the remaining feed adhering to the inner wall is blown off, thereby improving the scraping effect.

[0016] The beneficial effects of the utility model are:

[0017] The rotating stirring blades can stir and disperse the feed particles while drying them, thereby increasing the contact area between the feed particles and the hot air, so that the granular feed can be dried evenly and fully. At the same time, the scraper can scrape the feed on the inner wall of the device body when the stirring blades are stirring, and cooperate with the roller to avoid direct contact between the scraper and the inner wall of the device to cause wear. The sealing sleeve arranged at one end of the scraper can connect the air nozzle while the scraper is scraping the feed on the inner wall. After the scraper scrapes off the feed adhered to the inner wall, the air sprayed from the air nozzle cleans the feed directly adhered to the inner wall that cannot be cleaned by the scraper, thereby improving the cleaning effect and reducing the cost of subsequent maintenance.
