Abstract
The utility model discloses an automatic slag discharging device, comprising a motor, a transmission box, a feeding pipe, a conveying pipe and a discharging pipe, wherein the feeding pipe, the conveying pipe and the discharging pipe are internally provided with a conveying screw rod, a feeding opening is arranged above the feeding pipe, a discharging opening is arranged below the discharging pipe, a slag discharging opening is formed at the tail end of the discharging pipe, and a valve is arranged between the slag discharging opening and the discharging pipe. The automatic slag discharging device is capable of automatically discharging and filtering slag, is convenient to use; the operation process is instantly completed and the device does not need to be shut down in the operation process, thereby improving the production efficiency. Moreover, for ensuring the temperature of material, an electromagnetic heater is arranged at the periphery of the discharging pipe and used for providing heat to a core part; since a sleeve is arranged for blocking heat, the heat loss is reduced and the outside temperature of the automatic slag discharging device is about 40 DEG C, thus achieving good safety.
Description
Technical field
The utility model relates to a kind of contaminant filter treating apparatus, is specifically related to a kind of automatic slag-draining device, is used for the again material screening of granulation process of waste plastics recovery.
Background technology
In the plastics recovery process, some waste plastics obtain recycling behind the new material through extruding through after cleaning, fragmentation and adding auxiliary agent.But because material impurity is more, and material properties is diversified in specifications, must be furnished with impurity and process and screening process in the reprocessing process.Original plate-type screen changer is the equipment of realizing this operation, but this device is when screening, clean-up performance according to material is different, also need to change continually filter screen, and the frequency of changing filter screen is at 5～10 minutes/time substantially, needs shutdown operation during replacing, has directly reduced the real time of equipment operation, reduce operating efficiency, and increased workman's labour intensity; In addition, during owing to the replacing filter screen, equipment is through after the running (mainly being extruding and the friction of material) of certain hour, and temperature reaches 150～170 degrees centigrade, and workman at high temperature processing ease is scalded by equipment, has very large potential safety hazard.
The utility model content
The utility model purpose: the purpose of this utility model is in order to solve above the deficiencies in the prior art, the automatic slag-draining device that a kind of production efficiency is high, security is good, easy to operate to be provided.
Technical scheme: automatic slag-draining device described in the utility model, its objective is such realization: a kind of automatic slag-draining device, comprise motor, transmission case, feed pipe, carrier pipe, discharge nozzle, be provided with conveying screw rod in described feed pipe, carrier pipe and the discharge nozzle, described transmission case connects conveying screw rod, and described feed pipe top is provided with charging aperture, and described discharge nozzle below is provided with discharging opening, the end of described discharge nozzle is provided with slag-drip opening, is provided with valve between described slag-drip opening and the discharge nozzle.
Described discharge nozzle inwall is provided with screen pack, separates by screen pack between discharging opening and the conveying screw rod.
Be provided with internal diameter reducing flange from the coarse to fine between described valve and the discharge nozzle, flange inner wall is provided with pressure sensor.
Described carrier pipe and discharge nozzle outer wall are provided with sleeve, are provided with electromagnetic heater between sleeve and carrier pipe outer wall and sleeve and the discharge nozzle outer wall.
Beneficial effect: automatic slag-draining device described in the utility model, use single conveying screw rod to be integrated, the outside of conveying screw rod, the inside of discharge nozzle are provided with large-area screen pack, impurity in the material is after being stacked into certain amount between conveying screw rod and the screen pack, produce certain pressure, be arranged on the variation that pressure sensor on the flange inner wall detects pressure, automatically open the valve of slag-drip opening, impurity is discharged, when material thin and evenly the time, by screen pack the high-quality material is discharged from discharging opening; Whole operating process moment finishes, and does not need shutdown operation.Simultaneously, in order to ensure the temperature of material, adopted electromagnetic heater in the discharge nozzle periphery, from the core heating, added the upper bush thermal resistance, reduced the loss of heat, the slag-discharging device external temperature is about 40 degrees centigrade, and security is good.
