Abstract
The invention discloses a dust collector with a cold air device, which is suitable for a dust removing device matched with a roller type dryer in a process of producing dry-mixed mortar in the building industry. The dust collector comprises an air inlet, a shell, a filter, a draught fan and a cold air system. By adopting the dust collector, the filter can be well protected from being burnt, the environment pollution is reduced, the maintenance downtime is reduced, and the working efficiency is increased.
Description
Technical field
Belong to building field, relate in a kind of dry powder and mortar production process and the supporting dust arrester of roller dryer.
Background technology
Because what roller dryer adopted is the hot-air seasoning pattern, in its exit, when material lacks in dryer start just or the machine, outlet temperature is quite high, the supporting dust arrester of existing and roller dryer generally all is that the air inlet that is connected with dryer is arranged, filter, compositions such as air-introduced machine, its operation principle are that the air that contains dust that comes out from dryer enters dust arrester from air inlet, filter out dust by filter, be discharged to atmosphere through filtered air from fan out draft,, often cause the too high temperature of air that enters dust arrester owing to can not control inlet temperature, easily the filter that plays a role in filtering is burnt, make dust arrester forfeiture partial function, thereby cause environmental pollution, the equipment cisco unity malfunction, change filter lost labor and material, bring inconvenience to use
Summary of the invention
At above defective, the present invention proposes a kind of dust arrester with cooling air unit, comprises air inlet, housing and filter, and air-introduced machine is characterized in that: also comprise quenching system; Its quenching system comprises, cold blast sliding valve, detector, control system; Detector is contained in the air inlet place, survey the EAT of air inlet and send signal to control system, cold blast sliding valve is contained in the side of air inlet, when closing with air inlet duct and isolated from atmosphere, when opening air inlet duct is communicated with atmosphere, control system is that temperature signal and design temperature that detector transmits are compared, when temperature meets or exceeds design temperature, send instruction, cold blast sliding valve is opened, when temperature is lower than design temperature, cold blast sliding valve is closed, thereby guarantee to be no more than design temperature, avoided burning the generation of filter phenomenon by the temperature of filter.
Beneficial effect
Owing to adopted cooling air unit, avoided burning filter, reduced maintenance downtime and waste of material, improved operating efficiency.
Description of drawings
Fig. 1 is a schematic diagram of the present invention, 1. air inlets wherein, 2. cold blast sliding valve and detector, 3 control systems, 4. housing and filter, 5. air-introduced machine.
The specific embodiment
Air inlet is connected with the air outlet of roller dryer, cold blast sliding valve and detector are installed on the air inlet, housing is connected with air inlet, filter is contained in the housing, the air inlet of air-introduced machine is connected with the other end of housing, when equipment starts, the hot blast of discharging from the dryer air outlet enters dust arrester through air inlet, detector detects the temperature of air inlet and sends control system to, and the air that enters filter filters through filter, is discharged by air-introduced machine and enters atmosphere, when the detected temperature of detector surpasses the temperature of control system setting, control system is sent instruction, makes cold blast sliding valve open, and makes air inlet be communicated with atmosphere, because atmospheric temperature is well below the temperature of the air of dryer discharge, make the temperature that enters filter through air inlet reduce rapidly, just guarantee that filter is not burnt, when the detected temperature of detector is lower than the temperature that control system sets, in order to increase work efficiency, control system is sent instruction, makes cold blast sliding valve close, the equipment operate as normal.
Claims (2)
1. the dust arrester with cooling air unit comprises air inlet, housing and filter, and air-introduced machine is characterized in that: also comprise quenching system.
2. a kind of dust arrester according to claim 1 with cooling air unit, it is characterized in that: its quenching system comprises, cold blast sliding valve, detector, control system; Detector is contained in the air inlet place, survey the EAT of air inlet and send signal to control system, cold blast sliding valve is contained in the side of air inlet, with air inlet duct and isolated from atmosphere, when opening air inlet duct is communicated with atmosphere when closing, control system is that temperature signal and design temperature that detector transmits are compared, when temperature meets or exceeds design temperature, send instruction, cold blast sliding valve is opened, when temperature is lower than design temperature, cold blast sliding valve is closed.
