Abstract
A kind of direct injection level Four of the utility model pulverizes wear-resisting type blower mill, belong to Utility Boiler Technology field, it is characterized in that wear-resistant hammer head and abrasion-proof backing block composition coal mill system, coal mill system is divided into level Four, loading hopper is installed on the sidewall of shell, abrasion-proof backing block is installed in the inner side of shell, and wear-resistant hammer head and fan are installed on main shaft.Adopt the direct injection level Four of the utility model design to pulverize wear-resisting type blower mill, there is the advantages such as efficiency is high, stable, long service life, solve short technical barrier of existing coal-grinding technical equipment life-span.
Description
Technical field
The utility model relates to Utility Boiler Technology field, and particularly a kind of direct injection level Four pulverizes wear-resisting type blower mill.
Background technology
Along with the development of Control of Industrial Boiler Burning Processes technology, power-saving technology, a kind of efficient compound burning technology for chain-grate boiler arises at the historic moment, this technology sprays into boiler after coal is worn into necessarily thin coal dust, realizes the compound combustion of coal dust and coal cinder, improve boiler efficiency.But in use find that there is two problems, one be pulverized coal particle excessive time can cause spraying into boiler after can not burn instantaneously, over-emitting black exhaust (burning insufficient), and easy blocking pipe; Two is that the wear time of wearing piece is too short, changes frequent, affect production efficiency, increase use cost.
Summary of the invention
For solving the technical barrier that existing coal-grinding technology exists, the utility model takes following technical scheme:
A kind of direct injection level Four pulverizes wear-resisting type blower mill, it is characterized in that wear-resistant hammer head and abrasion-proof backing block composition coal mill system, coal mill system is divided into level Four, and loading hopper is installed on the sidewall of shell, abrasion-proof backing block is installed in the inner side of shell, and wear-resistant hammer head and fan are installed on main shaft.
Further, the diameter of main shaft is 80 ~ 150mm.
Further, the spacing between wear-resistant hammer head and abrasion-proof backing block is 1 ~ 5mm.
Further, the diameter of fan is 400 ~ 1200mm.
Accompanying drawing explanation
Fig. 1 is the structure chart that a kind of direct injection level Four of the utility model pulverizes wear-resisting type blower mill.
In figure, 1 is belt pulley, and 2 is fan, and 3 is abrasion-proof backing block, and 4 is wear-resistant hammer head, and 5 is shell, and 6 is loading hopper, and 7 is main shaft, and 8 is bearing.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model content is described further.
A kind of direct injection level Four pulverizes wear-resisting type blower mill structure chart as shown in Figure 1, and 1 is belt pulley, and 2 is fan, and 3 is abrasion-proof backing block, and 4 is wear-resistant hammer head, and 5 is shell, and 6 is loading hopper, and 7 is main shaft, and 8 is bearing.A kind of direct injection level Four pulverizes wear-resisting type blower mill, it is characterized in that wear-resistant hammer head 4 and abrasion-proof backing block 3 form coal mill system, coal mill system is divided into level Four, and loading hopper 6 is installed on the sidewall of shell 5, abrasion-proof backing block 3 is installed in the inner side of shell 5, and wear-resistant hammer head 4 and fan 2 are installed on main shaft 7.
Further, the diameter of main shaft 7 is 80 ~ 150mm.
Further, the spacing between wear-resistant hammer head 4 and abrasion-proof backing block 3 is 1 ~ 5mm.
Further, the diameter of fan 2 is 400 ~ 1200mm.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
