Abstract
The utility model relates to an anti-blocking blanking device. The utility model is composed of a blanking device, a jet pipe, and a pulse electromagnetic valve, wherein, an air inlet of the electromagnetic valve is communicated with a pressure air source or an air pump. When the utility model works, the electromagnetic valve is automatically turned on at intervals. The jet pipe ejects pulse airflows. Bulk materials on a blanking port part are forced out by the impact of the periodic airflows. Thereby, the bulk materials are effectively prevented from being blocked. The utility model has the advantages of simple structure and convenient use, and is applied to various blanking facilities of industrial equipment.
Description
The utility model relates to a kind of doffer, particularly a kind of doffer that prevents that loose light material from stopping up.
During present Detroit automation is produced, after many devices carry out certain processing with material, from the taper of bottom or cylindricality doffer, fall discharge, if material is loose light material (the loose filter mud after handling as the waste material from sugar refinery drying etc.), then in the blanking process, be easy to produce the bridge formation latch up phenomenon, often need artificial block clearing, influenced normally carrying out of producing.
The purpose of this utility model is to provide a kind of anti-blocking doffer that can prevent that loose light material from stopping up.
The utility model as shown in Figure 1, include doffer (1), be characterized in also including jet pipe (2) electromagnetic valve (3), wherein jet pipe (2) one ends stretch into the inner chamber of doffer (1), nozzle (21) is facing to blanking port (11), the other end connects with the air extractor duct (31) of electromagnetic valve (3), and the admission port (32) of electromagnetic valve (3) communicates with pressure gas source or air pump.
During the utility model work, the admission port (32) of electromagnetic valve (3) communicates with pressure gas source or air pump, when electromagnetic valve (3) under manual control or automatic guidance during conducting, the material that jet pipe (2) ejection impact air-flow is located blanking port (11) is subjected to gas shock and falls, avoid the obstruction of blanking port, thereby realized the purpose of this utility model.
Above-mentioned electromagnetic valve (3) can be selected general solenoid valve for use or dispose the pulse-controlled electromagnetic valve of pulse instrument, and general solenoid valve generally is used for the occasion that less generation is stopped up by the manual control conducting; Impulse electromagnetic valve conducting automatically regularly, intermittent time is set according to the material situation, and the degree of automation height is easy to use, is fit to the occasion that easily generation is stopped up.
Above-mentioned jet pipe (2) is fixed on the sidewall of doffer (1) by anchor fitting (4), and its nozzle is over against blanking port (11) center, and the setting height(from bottom) of jet pipe (2) is generally 1.5～3 times of blanking port (11) diameter and is advisable.
The utility model is simple in structure, degree of automation is high, easy to use, effective, can effectively prevent the obstruction of bulk material, be applicable on the blanking facility of various process equipments.
Fig. 1 is the utility model structural representation.
Embodiment: this is for example shown in Figure 1, form by doffer (1), jet pipe (2), anchor fitting (4) and electromagnetic valve (3), wherein doffer (1) is the conical hopper shape, anchor fitting (4) includes permanent seat (41) and adapter plate (42), permanent seat (41) centre has the hole and is connected with doffer (1) sidewall, adapter plate (42) is fixed on the jet pipe (2), jet pipe (2) passes permanent seat (41) and is connected by adapter plate (42) and permanent seat (41), thereby is fixedly mounted on doffer (1) sidewall.This routine jet pipe (2) setting height(from bottom) is 2 times of the straight warp of blanking port (11), and electromagnetic valve (3) configuration JTM-1 type pulse instrument is formed pulse-controlled electromagnetic valve, and electromagnetic valve (3) admission port (32) joins with 2V-0.2/7 type air pump, and about 6Kg/cm is provided
2The pressure gas of pressure.Electromagnetic valve during work (3) is pressed setting-up time intermittently conducting automatically, jet pipe (2) ejection air pulse, and the material that blanking port (11) is located is subjected to the impact of cycle air-flow and is swept away, and has avoided latch up phenomenon effectively.
Claims (5)
