Description

Dust pelletizing system is smashed to mineral

Technical Field

The utility model relates to a mineral processing dust removal technical field especially relates to a dust pelletizing system is smashed to mineral.

Background

In mineral processing, there is often a crushing step, which results in high dust. High dust can not only seriously harm the health of workers working in the environment for a long time, but also pollute the environment. The pulse dust collector is air purifying equipment which is frequently used in each high-dust place, and has great effect on workers and the environment when people work in the high-dust places effectively purify dust.

The traditional pulse dust collector generally adopts a filter bag for filtering, and the working principle is as follows: when the dust-containing gas enters the dust remover from the air inlet, the dust-containing gas is trapped on the outer surface of the filter bag when passing through the filter bag, the gas passing through the filter bag is purified gas, the purified gas enters a cleaning chamber at the upper part of the filter bag chamber and is collected to the air outlet to be discharged, and during the purification process of the dust-containing gas passing through the filter bag, the dust accumulated on the filter bag is more and more along with the increase of time, the resistance of the filter bag is increased, so that the air volume to be treated is gradually reduced, for normal work, the resistance is controlled within a certain range, once the resistance exceeds the range, the filter bag needs to be cleaned, a pulse controller sequentially triggers each control valve to open a pulse valve during dust cleaning, compressed air in an air bag is sprayed into each corresponding filter bag through each hole of a spray pipe through a venturi tube, the filter bag rapidly expands instantly, the dust accumulated on the surface of the filter bag falls off, and the filter bag returns to the initial state. The dust falls into the dust hopper and is discharged out of the machine body through the dust discharging system. Therefore, dust accumulated on the filter bag is periodically and pulse-sprayed to remove ash, purified gas normally passes through the filter bag, and the operation of a dust removal system is ensured. However, the traditional pulse dust collector basically depends on the rapid expansion of the filter bag in the dust removal and blowing processes to realize the falling and threshing of the dust deposited on the filter bag; the key of the blowing process is that the high-speed airflow sprayed by the air bag and the characteristic that the filter bag can deform are relied on; therefore, the requirements on the material of the filter bag and the capability of the air flow sprayed by the air bag are very high; especially, the filter bag is easy to deform after being repeatedly blown, so that the filter holes on the filter bag are gradually enlarged, the filter quality is reduced, and therefore, common enterprises need to replace the filter bag regularly, and the production cost is high.

In order to enable the air flow sprayed by the purging pipe 63 to be relatively turbulent and effectively improve the collision amount of the air flow and the spiral flow guide structure 41, a plurality of spiral rifling lines are arranged on the inner wall of the outlet end of the purging pipe 63; after the gas flow is guided by the spiral rifling, the gas flow is spiral after coming out from the outlet end of the purging pipe 63. In actual use the control valve 62 may be a conventional pulse valve or a diaphragm valve, since in this application the purge line 63 is not required to eject the gas stream mass at high speed for a short period of time; the gas pressure of the gas bag 61 is not necessarily too high in practical use, and since the purging process of the purging device 6 can be a continuous purging or a pulse purging, the product performance requirements and the control requirements of the gas bag 61 and the control valve 62 are relatively low in the present application, and therefore the use cost is relatively low.
