Abstract
The utility model relates to a spiral feeding device, which comprises a first feeding cylinder arranged inside a furnace hearth, and a second feeding cylinder arranged outside the furnace hearth. A spiral feeding channel is arranged in the first feeding cylinder, a feeding chamber is formed in the second feeding cylinder, one port of the spiral feeding channel is communicated with the feeding chamber, and the other port is communicated with a heating chamber inside the furnace hearth; and the feeding channel is designed as a spiral feeding channel, which can rotate together with a roller to feed processing material into the furnace. The feeding device can effectively separate the feeding end from the heating chamber, prevent the direct radiation loss of high-temperature heat of the heating chamber, and prevent a great amount of protective atmosphere inside the furnace from overflow and loss, and has very perfect energy-saving effect.
Description
Technical field
The utility model relates to a kind of screw feeding device.
Background technology
In the prior art, all offer opening for feed on the furnace wall of general heat treatment furnace, when needs during, as long as directly workpiece is sent in the heating chamber in the stove by this opening for feed to furnace charge.But; owing to all be filled with protection gas in the heat treatment furnace; and the temperature of stove internal heating chamber is very high; when passing through the opening for feed feeding; will certainly escape to the stove outside by some protection gas; cause the loss of protection gas, and the heat of high temperature in the heating chamber also can cause calorific loss directly to the stove external irradiation.
Summary of the invention
The purpose of this utility model provides a kind of screw feeding device of good energy-conserving effect.
For achieving the above object, the technical solution adopted in the utility model is: a kind of screw feeding device, comprise first feeding cylinder that is arranged in the burner hearth, be arranged on the second outer feeding cylinder of burner hearth, be provided with the volution feeding-passage in described first feeding cylinder, the described second feeding cylinder inner chamber forms feed chamber, one port of described volution feeding-passage is connected with described feed chamber, and the another port is connected with the heating chamber of burner hearth inside.
Be filled with lagging material in described first feeding cylinder.
The utility model compared with prior art has following advantage: feeding-passage is the volution feeding-passage, thereby it can will add labor and materials and send in the stove along with cylinder rotates together.This feeding unit can effectively intercept feed end and heating chamber, prevents the direct radiation loss of heating chamber heat of high temperature, and a large amount of excessive loss of the interior protective atmosphere of stove, has very ideal energy-saving effect.
Description of drawings
Accompanying drawing 1 is looked sectional view for master of the present utility model;
Wherein: 1, first feeding cylinder; 2, second feeding cylinder; 3, feed chamber; 4, volution feeding-passage; 5, lagging material; 6, cylinder; 7 dividing plates.
Embodiment
A kind of screw feeding device that is installed in the rotary drum furnace as shown in Figure 1, body of heater is the cylinder 6 of a rolling, and a dividing plate 7 is installed on the cylinder 6, this dividing plate 7 is with inside and outside separating of burner hearth (drum cavity).Screw feeding device comprises first feeding cylinder 6 that is fixedly installed in the cylinder 6, be fixedly installed on the second outer feeding cylinder 2 of cylinder 6.Separate fully by dividing plate 7 between first feeding cylinder 1 and second feeding cylinder 2.
Be provided with volution feeding-passage 4, the second feeding cylinders 2 inner chambers in first feeding cylinder 1 and form feed chamber 3, a port of volution feeding-passage 4 is connected with feed chamber 3, and another port and cylinder 6 interior heating chambers are connected.
As shown in the figure, be filled with in first feeding cylinder 1 between lagging material 5, the first feeding cylinders 1 and the cylinder 6 and also be filled with lagging material, these lagging materials can be selected common aluminum silicate fiber lagging material for use.
When the heating chamber charging in cylinder 6, at first material is sent in the feed chamber 3 in second feeding cylinder 2, material in the feed chamber 3 enters in the volution feeding-passage 4 by the port in the volution feeding-passage 4 again, volution feeding-passage 4 is in along with cylinder 6 rotating process, in the heating chamber of expecting progressively to send in the cylinder 6.This screw feeding device can make stove when charging, and heat can not be radiated outside the stove by feeding-passage, and the also difficult effusion of furnace gas, can reach the loss that the loss that reduces protection gas has reduced heat simultaneously again.
Claims (2)
1, a kind of screw feeding device, it is characterized in that: comprise first feeding cylinder (1) that is arranged in the burner hearth, be arranged on outer second feeding cylinder (2) of burner hearth, be provided with volution feeding-passage (4) in described first feeding cylinder (1), described second feeding cylinder (2) inner chamber forms feed chamber (3), one port of described volution feeding-passage (4) is connected with described feed chamber (3), and the another port is connected with the heating chamber of burner hearth inside.
