Abstract
The invention relates to a dust collection device for a casting workshop. The dust collection device comprises a fan, a pipeline, a cloth bag, an air inlet device and a driving device, wherein the fan is assembled in the pipeline; the cloth bag is connected with one end of the pipeline; the section of the pipeline is L-shaped; the air inlet device comprises an L-shaped air inlet pipe and a bearing; the bearing is fixed in the air inlet pipe; the end part of the pipeline is fixedly connected with an inner ring of the bearing; the driving device comprises a driving motor, a driving gear and a driven gear; the output end of the driving motor is fixedly connected with the driving gear; the driven gear is fixed on the outer wall face of the pipeline; the driven gear is meshed with the driving gear. The dust collection device can suck airflow in the workshop environment all around so as to remove dust contained in the airflow.
Description
Technical field
The present invention relates to a kind of dust arrester of foundry.
Background technology
Along with development and the raising of casting technique, China's casting industry extensively adopts feeds resin, phenolic resins sand molding from firmly reflecting, and this not only shortens the production cycle, improves production efficiency, but also improves the presentation quality of foundry goods.But, sand mo(u)ld after phenolic sand molding is when pouring into a mould and cool, dense flue gas can be given out at the dead head of sand mo(u)ld, because of the barbecue by high temperature liquid iron, exhaust gas components not only has flue dust and carbon monoxide, and producing the larger resin volatile matter of a kind of ratio of viscosities simultaneously---tetrahydrochysene reflects the food in one's mouth (its viscosity can reach 30mPa.s 20 DEG C time), it and flue gas mix and can produce the greasy composition granule of the very strong and inflammable black of viscosity, be easy to be bonded on the tube wall of dust removal by ventilation pipeline and the filter bag of sack cleaner, time one length makes resistance of the filter bag increase, until blocking, cause sock filtration disabler, have a strong impact on dust removing effects.So, current domestic casting industry is on phenolic sand molding production line, the flue gas of all cast sections and cooling section generally all adopts blower fan in line, deduster is not set, the consequence done like this is that discharge cannot be up to standard, smoke contamination air, and be 30mg/m by the cast of newly-built enterprise specified in " the National Standard of the People's Republic of China one foundary industry atmosphere pollutants emission standards " promulgated, the concentration of emission limit value of cooling section
3.Reaching this requirement, must administer the flue dust of casting and pouring, cooling section, could discharge after up to standard, also just must solve resin and play thing---tetrahydrochysene reflects the technical barrier of feeding dust bonding filter bag.
Summary of the invention
For above-mentioned technical problem, the object of the present invention is to provide a kind of dust arrester of foundry, the present invention can absorb the air-flow in workshop condition in all directions, to remove flue dust contained in air-flow.
The technical scheme solved the problems of the technologies described above is as follows:
The dust arrester of foundry, comprise blower fan, pipeline, cloth bag, blower fan assembling in the duct, cloth bag is connected with one end of pipeline, the cross section of described pipeline is L-shaped, also comprise inlet duct and drive unit, inlet duct comprises air inlet pipe and the bearing of L-type, described bearing is fixed in air inlet pipe, the end of described pipeline is fixedly connected with the inner ring of bearing, drive unit comprises drive motors, driving gear and driven gear, the axle of drive motors goes out end and is fixedly connected with driving gear, driven gear is fixed in the outside wall surface of pipeline, driven gear and driving gear engage each other.
Have employed such scheme, inlet duct comprises air inlet pipe and the bearing of L-type, described bearing is fixed in air inlet pipe, the end of described pipeline is fixedly connected with the inner ring of bearing, drive unit comprises drive motors, driving gear and driven gear, the axle of drive motors goes out end and is fixedly connected with driving gear, and driven gear is fixed in the outside wall surface of pipeline, and driven gear and driving gear engage each other.When being worked by drive motors, drive driving gear rotates, driving gear drives driven gear to rotate, and driven gear drives air inlet pipe to rotate, thus makes air inlet pipe can 360 degree of rotations, its air inlet port when rotating as environment in the inlet end of all directions, air-flow in surrounding environment can be absorbed like this, expand absorption region, and by bearing, pipeline is connected with air inlet pipe, avoid directly being connected with pipeline of air inlet pipe, worn and torn in rotation process.
Further, the side face of described pipeline is provided with step, the axial end of this step is provided with annular protrusion, the axial end of described air inlet pipe is provided with annular sealing member, this annular sealing member is provided with cannelure, when the end of pipeline is inserted into after bearing, described annular protrusion is inserted in the cannelure on annular sealing member.By the sealing function formed between annular protrusion and annular sealing member, avoid in breathing process, leak gas due to the gap between pipeline and air inlet pipe.
