Abstract
The utility model relates to a dust removing device at the turning-over point of a coal conveyor belt, which comprises a dust remover. An outlet of the dust remover is communicated with a blower. A suction opening of the dust remover is communicated with a dust removing opening of a dust cover. A coal falling opening is arranged on the dust cover. The dust cover is arranged on the conveyor belt. An outlet of the dust cover is provided with dust blocking curtain. The utility model is characterized in that the dust removing device at the turning-over point of a coal conveyor belt also comprises an inner dust cover or an outer dust cover which is added in the dust cover or outside the dust cover. The dust removing device at the turning-over point of a coal conveyor belt has certain negative pressure at the combining part of the conveyor belt and the dust cover. The negative pressure is not needed in the whole dust cover. The dust removing device at the turning-over point of a coal conveyor belt can satisfy the requirements of the environment protecting indexes. Therefore, the utility model has the advantages of small exhaust air rate, low dust concentration in exhausted airflow, simple structure, low manufacturing cost, etc.
Description
A kind of defeated coal conveyer belt reloading point dust arrester is specially adapted to the dedusting that Thermal Power Station fails coal conveyer belt reloading point.
The conveyer belt of existing defeated coal conveyer belt reloading point dust arrester is provided with single dust cover structure, when the conveyer belt of coal in coal dropping port falls into dust cover, go into portion of air in the dust cover with the ribbing, also claim: induced air, when the dustproof exhaust air rate of putting dust-exhausting port when inducing air quantity, be malleation in the dust cover, the dust of coal outwards overflows from the gap of dust cover and conveyer belt binding site; When the exhaust air rate of dust cover dust-exhausting port is equal to or greater than when inducing air quantity, the horizontal wind speed in the dust cover is very high, adds the speed of service of upper conveyor belt, and the dust in the dust cover outwards overflows from the dust-break curtain of dust cover under the effect of inertia force.The coal dust dust concentration of overflowing surpasses the index of environmental regulations, and environment is polluted.
The purpose of this utility model is prior art is improved, and provides that a kind of exhaust air rate is little, discharging air-flow, to contain dust concentration low, can satisfy the environmental protection index requirement, defeated coal conveyer belt reloading point dust arrester simple in structure, cheap for manufacturing cost.
The purpose of this utility model is realized by following technical scheme: defeated coal conveyer belt reloading point dust arrester, it comprises: deduster 22, the outlet 14 of deduster 22 is communicated with blower fan 1 by pipeline, the suction inlet 15 of deduster 22 is communicated with the dust-exhausting port 7 of dust cover 10 by pipeline, on dust cover 10, be provided with coal dropping port 12, dust cover 10 places on the defeated coal conveyer belt 9, is provided with dust-break curtain 11 in the outlet of dust cover 10, it is characterized in that: also be included in be provided with in the dust cover 10 in dust cover 8.
Or dust cover 23 outside outside dust cover 10, being provided with, dust cover 23 is provided with dust-exhausting port 21 outside, and the dust-exhausting port 21 of outer dust cover 23 is communicated with dust excluder 22 by pipeline.
During dust cover 8, in interior dust cover 8, dust-break curtain 20 is set in dust cover 10, being provided with.
During dust cover 23, dust-break curtain 20 is set in dust cover 10 outside outside dust cover 10, being provided with.
Defeated coal conveyer belt reloading point dust arrester of the present utility model is compared with existing same device, since dust arrester of the present utility model be in dust cover, being provided with dust cover or outside dust cover, be provided with outside the structure of dust cover, the blower fan that is communicated with deduster only extracts the dust laden air in the flow-guiding channel, can not directly extract coal dropping port and fall into the interior induced air of dust cover, therefore malleation is formed at dust cover top, and flow-guiding channel is a negative pressure, can reduce induced air like this, the air-flow dust content of extraction is reduced, no dust outwards overflows from dust cover, avoid environmental pollution, had advantages such as simple in structure, cheap for manufacturing cost.
The utility model is described in further detail to utilize embodiment shown in the drawings below.
