Abstract
The utility model belongs to a machine accessory, in particular to an impulse wheel in a high efficient hard wearing fan coal grinding machine. The high efficient hard wearing fan coal grinding machine impulse wheel is composed of a roulette, a hitting board, a soleplate, a U shaped beam, a support beam and a support plate; a connecting bridge; wherein the soleplate, the U shaped beam, the support beam and the supporting board form a connecting bridge; the U shaped beam is welded on the soleplate, while the support beam is welded between the U shaped beam and the support board; the support board and the U shaped beam is connected by welding; the hitting board is fixed on the support board, while the soleplate is fixed on the soleplate. The utility model adopts a non cast steel welding structure, each connecting bridge of which is identical in weight, and thus improving rotating balance of the impulse wheel; operation of the complete machine is stable, the noise is reduced and the service life is extended three to four times.
Description
Technical field
The utility model belongs to mechanical fitting, particularly a kind of high-efficiency abrasion-proof blower mill beater wheel.
Background technology
Blower mill is that the thermal power plant uses the main equipment that boiler using brown coal blows the formula pulverized coal preparation system, blower mill is mainly formed by the casing that has backplate with at the beater wheel of casing high speed rotation, rough coal enters in the machine, by the beater plate on the beater wheel that runs up with the rough coal fragmentation.Beater plate is fixed on the beater wheel by tie-beam, because beater wheel is parts that run up, the quality requirement of tie-beam wherein has higher homogeneity.At present, fixedly the tie-beam of shock plate adopts steel-casting, because the quality inhomogeneities of foundry goods, as pore, cause the homogeneity of casting weight poor, directly influence the dynamic balancing of beater wheel running, the bulk strength of foundry goods is relatively poor simultaneously, and life cycle is short, and security performance can't ensure.
Summary of the invention
The purpose of this utility model is to provide a kind of prior art shortcoming that overcomes, the blower mill beater wheel of raising service efficiency.
The purpose of this utility model realizes by following technical measures: the blower mill beater wheel, form by wheel disc, beater plate, base plate, U type beam, brace summer, gripper shoe, constitute tie-beam by base plate, U type beam, brace summer, gripper shoe, wherein U type beam is welded on the base plate, brace summer is welded in the middle of U type beam and the gripper shoe, gripper shoe and U type beam are welded to connect, and beater plate is fixed on the gripper shoe, base plate is fixed on the wheel disc.
Described beater plate adopts high strength steel plate, and pile-up welding hard alloy is connected with gripper shoe.
The utility model adopts the Welding Structure of non-cast steel structure, and the weight of each tie-beam is identical, has improved beater wheel running dynamic balancing, and the complete machine running is steady, and noise reduces, and prolongs 3-4 service life doubly.
Description of drawings
Fig. 1 is the utility model structure chart.
The specific embodiment
With reference to accompanying drawing 1, blower mill beater wheel, form by wheel disc 5, beater plate 6, base plate 1, U type beam 3, brace summer 2, gripper shoe 4, constitute tie-beam by base plate 1, U type beam 3, brace summer 2, gripper shoe 4, wherein U type beam 3 is welded on the base plate 1, brace summer 2 is welded in the middle of U type beam 3 and the gripper shoe 4, gripper shoe 4 is welded to connect with U type beam 3, and beater plate 6 is fixed on the gripper shoe 4, base plate 1 is fixed on the wheel disc 5.
Claims (1)
