Blending device for rotating speed and sand inlet amount of rotary drum type sand drying equipment

Abstract

The invention relates to the technical field of sand drying, and discloses a blending device for the rotating speed and the sand inlet amount of rotary drum type sand drying equipment. The blending device comprises a shell, a driving mechanism is movably connected in the shell, the left side and the right side of the driving mechanism are movably connected with limiting rods, reset springs are fixedly connected to the bottom of the driving mechanism, the bottom of the driving mechanism is movably connected with an adjusting mechanism, and the top of the adjusting mechanism is movably connected with a speed adjusting mechanism. Through internal stress compression of an energy-gathering spring, elastic potential energy is gathered inside, preparations are made for resetting of a moving rod, meanwhile, when the moving rod moves in the direction away from pressure blocks, a sliding piece is driven by a connecting rod to move together, and therefore the sliding piece slides on the outer surface of a sliding rheostat, the internal resistance value of the sliding rheostat is reduced, the rotating speed of a fan is increased, and then the effects that along with the sand inlet amount, the moving speed of a heat carrier is automatically controlled, and drying is accelerated are achieved.

Description

technical field [0001] The invention relates to the technical field of sand drying, in particular to a device for adjusting the rotating speed and sand feeding amount of a rotary drum type sand drying equipment. Background technique [0002] With the rapid development of the modern construction industry, the use of sand is also increasing day by day, so the use of sand drying equipment is also essential. The sand dryer is used to dry sand, river sand, quartz sand, casting Sand ideal equipment choice. [0003] However, when the sand dryer is in use, it is generally dried internally. Regardless of the size of the sand, its speed and the amount of heat transfer medium are constant. If the amount of sand is small, it is easy to waste energy. , if the amount of sand is too much, the speed and unit heat transfer volume at this time may not be enough, resulting in unqualified sand drying. [0004] Therefore, the demand for high-reliability products is imminent. Therefore, we have...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a device for adjusting the rotation speed of the drum-type sand drying equipment and the amount of sand input, which can automatically control the moving speed of the heat carrier according to the amount of sand input, and speed up the drying process. At the same time, the sand drying equipment has the advantage of automatically controlling the rotation speed of the drum according to the amount of sand entering, which solves the problem that when the sand dryer is in use, it is generally internally dried automatically, regardless of the amount of sand, its speed The amount of heat carrier transported is certain. If the amount of sand is small, it is easy to waste energy. If the amount of sand is too much, the speed and the amount of heat carrier transported per unit may not be enough at this time, resulting in insufficient sand drying. qualified questions
