Description

Technical Field

[0001] The utility model relates to the technical field of grate coolers, in particular to a grate cooler fan base assembly. Background Art

[0002] Grate cooler is a quench cooler. After the clinker enters the cooler from the kiln, it is spread on the grate plate to form a material layer of a certain thickness. The cold air blown in passes through the material layer moving on the grate bed in a perpendicular direction to quench the clinker. It is the main equipment for heat recovery in the cement clinker burning system.

[0003] The grate cooler uses a cooling fan, which is fixed by a base. When installing the cooling fan, after the base is placed on the ground, the cooling fan and the main body of the grate cooler may not be accurately connected due to the placement error of the lifting equipment when connecting them. It will be troublesome to move the cooling fan and the base again.

[0004] In view of this, we propose a grate cooler fan base assembly. Utility Model Content

[0032] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0033] Example 1: A grate cooler fan base assembly, see Figures 1 to 4 , comprising a base frame 1 and an adjustment frame 2;

[0034] The two base frames 1 are arranged symmetrically; wherein, connecting plates 101 are fixedly arranged at both ends of the bottom of the two base frames 1 on the opposite sides, and mounting holes are opened on the connecting plates 101, and expansion screws are passed through the mounting holes to position the connecting plates 101 on the ground, thereby positioning the base frames 1 on the ground; the bottom sides of the two adjustment frames 2 are slidably connected to the top sides of the two base frames 1 through the slide rails 4; wherein, two mounting plates 201 are symmetrically fixedly arranged between the two adjustment frames 2, and the bottom base of the cooling fan is mounted on the mounting plate 201 by screws; wherein, the two base frames 1 are adjusted and matched with the two adjustment structures 3 through the adjustment structure 3;

[0035] The adjustment structure 3 includes a fixed plate 301, a movable plate 302, a screw rod 303 and a stepping motor 305;

[0036] The two ends of the fixed plate 301 are fixedly connected to the opposite sides of the two base frames 1; the two ends of the top side of the movable plate 302 are fixedly connected to the bottom sides of the two adjustment frames 2; the screw rod 303 is threadedly arranged on the movable plate 302; wherein, the inner end of the screw rod 303 is rotationally connected to the fixed plate 301; the transmission shaft at the output end of the stepping motor 305 is transmission-connected to the outer end of the screw rod 303, and the stepping motor 305 is selected and used by the technicians in this profession according to the actual situation.

[0037] The utility model is provided with a base frame 1, an adjustment frame 2, a slide rail 4, a fixed plate 301, a movable plate 302, a screw rod 303 and a stepping motor 305. After the base frame 1 is placed on the ground, when it is found that the cooling fan and the main body of the grate cooler cannot be accurately docked, the position of the adjustment frame 2 relative to the base frame 1 is adjusted, thereby adjusting the distance between the cooling fan and the main body of the grate cooler to make them docked. This solves the problem that it is troublesome to move the cooling fan and the base again when the cooling fan and the main body of the grate cooler cannot be accurately docked.

[0038] Specifically, a support plate 304 is fixedly provided between one end of the two opposite sides of the two base frames 1, a stepper motor 305 is fixedly provided on the support plate 304, a control box 306 is fixedly provided on the top side of the support plate 304, the control box 306 has a built-in control module and is connected to the stepper motor 305, controls the forward and reverse rotation of the stepper motor 305, thereby driving the adjustment frame 2 to move forward or backward relative to the base frame 1.
