Abstract
The utility model provides a sealing device of a discharge port of a rotary drum dryer, wherein the lower part of the discharge port is provided with an air leakage prevention sealing plate, one side wall of the discharge port is provided with a hole, a sealing plate passing hole passes through the side wall of the discharge port, the sealing plate is movably connected with one side of the discharge port, one end of the sealing plate, which is far away from the discharge port, is downwards connected with a spring device, and the spring device is fixed on the side wall of the discharge port through a supporting structure; when discharging, the material gravity makes the sealing plate incline downwards, a gap is formed between the sealing plate and the inner side wall of the discharge hole, and the material is discharged out of the dryer; after the discharging is finished, the sealing plate is reset under the action of the tension of the spring. Through the tensile size of regulating spring, both guaranteed the normal ejection of compact of desiccator, avoided the discharge gate problem of leaking out again, effectively improved the drying efficiency of equipment.
Description
Technical Field
The utility model relates to a rotary drier subassembly especially relates to a sealing device of rotary drier discharge gate.
Background
The rotary dryer is widely applied to the manufacturing process of compound fertilizer. The working principle of the dryer is that materials and hot air enter from an inlet of the roller dryer and the hot air is in parallel flow contact with the materials. The rotary drum dryer has a certain inclination angle, generally 1-3 degrees, the material moves to the lower end under the action of gravity along with the rotation of the drum, and directly or indirectly exchanges heat with a heat medium in the process of moving the material forwards in the drum, so that the material is dried, and then the material is discharged from a discharge port below a furnace end of the discharge end dryer.
In order to reduce air leakage, the rotary drum dryer adopts different forms of mechanical seals between the feeding furnace end and the discharging furnace end of the rotary drum and the drum body, but neglects the air leakage problem in the discharging process of the discharging port. Because the top of furnace end links to each other with the dust remover, and the below is ejection of compact case, and ejection of compact case lower extreme is the discharge gate, when arranging the material, often takes place to leak out, not only causes the energy consumption of very big degree extravagant, seriously influences the drying efficiency of equipment moreover.
Disclosure of Invention
The utility model aims at providing a sealing device of rotary dryer discharge gate in order to solve the problem of leaking out of row material in-process.
The utility model aims at realizing through the following technical scheme:
the utility model provides a sealing device of rotary dryer discharge gate, its characterized in that, the lower part of discharge gate sets up the closing plate, discharge gate lateral wall trompil, closing plate clearing hole pass discharge gate lateral wall, closing plate and discharge gate lateral wall swing joint, the one end that the discharge gate was kept away from to the closing plate is connected with spring assembly downwards, and spring assembly passes through bearing structure and fixes at the discharge gate lateral wall.
The connection mode of the sealing plate and the side wall of the discharge hole is hinged or connected through a rotating shaft.
The spring support structure comprises a support shaft and a pair of support sheets, the support sheets are welded on two sides of the discharge port, and the spring is connected with the support shaft.
Further, the other end of the spring device adjusts the elastic force of the spring through a bolt and a nut, and the bolt penetrates through the supporting shaft through a hole.
The utility model has the advantages that:
through the utility model, during discharging, the gravity of the material makes the sealing plate incline downwards, and a gap is formed between the sealing plate and the inner side wall of the discharge port, so that the material is discharged out of the dryer; after the discharging is finished, the spring drives the sealing plate to reset under the action of the pulling force. Through the size of the tension of the adjusting spring, the gap of the discharge port is changed along with the discharge amount, the normal discharge of the dryer is ensured, the air leakage problem of the discharge port is avoided, and the drying efficiency of the equipment is effectively improved.
