Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of feed processing equipment, specifically relating to a drying device for feed production. Background Technology
[0002] In the feed processing industry, drying technology is a crucial step in ensuring feed quality. Its core lies in achieving rapid evaporation of moisture from the feed through efficient heat exchange.
[0003] Currently, most common feed drying equipment on the market uses traditional hot air drying methods. However, these devices have revealed many technical bottlenecks in practical applications. On the one hand, the hot air flow path in existing drying devices is short and lacks a guiding design, resulting in insufficient contact time between hot air and feed, low heat utilization, and slow feed moisture evaporation rate, making it difficult to meet the drying efficiency requirements of large-scale production. On the other hand, dust and other impurities carried in the air during the drying process are easily deposited inside the drying equipment with the airflow. Long-term accumulation may cause equipment blockage or even feed contamination, and traditional devices are not convenient for removing the dust deposited inside the equipment. Utility Model Content
[0004] This utility model addresses the shortcomings of existing technologies by providing a drying device for feed production, the specific technical solution of which is as follows:
[0005] A drying device for feed production includes a drying tube and a control box mounted on the side surface of the drying tube. A mesh belt conveyor for feed transport is installed along the axis inside the drying tube. An electric heating blower for heating the internal air is installed at the discharge end of the drying tube. An air outlet is opened on the upper surface of the end of the drying tube away from the electric heating blower for exhaust. A temperature sensor for detecting the internal temperature is installed on the inner surface of the upper part of the drying tube. Both the electric heating blower and the temperature sensor are electrically connected to the control box. A spiral air guide plate is welded to the inner surface of the drying tube. A dust baffle is welded to the bottom of the air guide plate. A flip-top plate for sealing is installed at the lower opening of the drying tube. A hinge for rotation is installed between one end of the flip-top plate and the drying tube. A detachable positioning component is installed between the other end of the flip-top plate and the drying tube.
[0006] Preferably, the electric heating blower includes a conduit welded to the end of the drying tube, a fan for discharging air into the drying tube is installed inside the conduit, a ceramic tube is fixed to the inner surface of the conduit, an electric heating wire for air installation is installed on the inner surface of the ceramic tube, a protective net for fan protection is provided at the open end of the conduit, and both the fan and the electric heating wire are electrically connected to the control box.
[0007] Preferably, there are three air guide plates arranged in a circular array, and the dust baffle is welded to the lower part of the three air guide plates.
[0008] Preferably, the positioning component includes a limiting groove formed at the end of the flip cover away from the hinge, and a screw adapted to the limiting groove welded to the surface of the drying tube. A washer is sleeved on the end of the screw, and the washer is installed on the outside of the flip cover. A wing nut for positioning the washer is screwed onto the end of the screw.
[0009] Preferably, the lower surfaces at both ends of the drying tube are welded with supports.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] 1. An electric heating blower is installed at the end of the drying pipe for air heating. This facilitates the conveyor belt transport of feed, and the heated air inside the drying pipe increases the evaporation rate of moisture in the feed, thus facilitating drying. The inner surface of the drying pipe is welded with a spiral-structured air guide plate, which guides the air blown into the drying pipe by the electric heating blower, increasing the path of hot air flow inside the drying pipe and thus increasing the drying temperature of the feed. The dust baffle plate welded to the bottom of the air guide plate blocks the air as it passes through the bottom of the drying pipe, allowing dust in the air to settle to the bottom of the drying pipe. A flip-top cover is installed at the lower opening of the drying pipe for sealing. One end of the flip-top cover is rotatably connected to the drying pipe via a hinge, and the other end is connected to the drying pipe via a positioning component, allowing dust to be discharged from the lower opening of the drying pipe when the flip-top cover is opened.
[0012] 2. The device consists of a duct, a fan, a ceramic tube, a heating wire, and a protective net. The fan installed inside the duct blows air into the drying tube, while the ceramic tube fixed inside the duct supports the heating wire, facilitating the heating of the air after the heating wire is energized. This allows the hot air to be blown into the drying tube to dry the feed. The protective net installed at the opening end of the duct protects the fan and improves the safety of the fan during operation.
[0013] 3. A positioning component consisting of a limiting groove, screw, washer, and wing nut is used. The screw on the surface of the drying tube is located in the limiting groove at the end of the cover plate. The wing nut at the end of the screw engages with the washer, so that the screw, washer, and wing nut work together to fix the cover plate to the drying tube. At the same time, the wing nut can be rotated in the opposite direction to facilitate the removal of the wing nut from the end of the screw. Attached Figure Description

A detachable positioning component is installed between the other end of the flip-top plate 6 and the drying pipe 1.
[0024] In this embodiment, an electric heating blower 3 for air heating is installed at the end of the drying pipe 1. This allows the heated air inside the drying pipe 1 to increase the evaporation rate of moisture in the feed during feed transport by the mesh belt conveyor 2, thus facilitating feed drying. The inner surface of the drying pipe 1 is welded with a spiral structure air guide plate 4, which guides the air blown into the drying pipe 1 by the electric heating blower 3, increasing the path of hot air flow inside the drying pipe 1 and thus increasing the drying temperature of the feed inside the drying pipe 1. The dust baffle 5 welded to the bottom of the air guide plate 4 blocks the air as it passes through the bottom of the drying pipe 1, allowing dust in the air to settle at the bottom of the drying pipe 1. A flip-top plate 6 for sealing is installed at the lower opening of the drying pipe 1. One end of the flip-top plate 6 is rotatably connected to the drying pipe 1 via a hinge 7, and the other end of the flip-top plate 6 is connected to the drying pipe 1 via a positioning component, allowing dust to be discharged from the lower opening of the drying pipe 1 when the flip-top plate 6 is opened.
