Abstract
The utility model relates to an anti-blocking rod for an inclinable rolling barrel type electric resistance rotary furnace cover air outlet pipe. The anti-blocking rod for the inclinable rolling barrel type electric resistance rotary furnace cover air outlet pipe comprises a furnace body, an inner container arranged in the middle of the furnace body and a cylinder-shaped furnace cover connected with the inner container. A cylinder-shaped furnace cover air outlet pipe is arranged in the middle of the cylinder-shaped furnace cover. The anti-blocking rod for the inclinable rolling barrel type electric resistance rotary furnace cover air outlet pipe is characterized in that an anti-blocking rod movably penetrates through the middle of the furnace cover air outlet pipe. Two ends of the anti-blocking rod are extended outside openings of two ends of the furnace cover air outlet pipe. Parts of the anti-blocking rod are at two ends of the anti-blocking rod and are extended outside the openings of the two ends of the furnace cover air outlet pipe and are bended into curved rods with certain angles to prevent the anti-blocking rod from sliding out from the furnace cover air outlet pipe. The anti-blocking rod is made by heat resisting round steels. The diameter of the anti-blocking rod is no more than one third of the inner diameter of the furnace cover air outlet. The anti-blocking rod for the inclinable rolling barrel type electric resistance rotary furnace cover air outlet pipe can prevent the furnace cover air outlet pipe from being blocked. Therefore kerosene added in the inclinable rolling barrel type electric resistance rotary furnace can be normally and completely combusted, quenched parts in the inclinable rolling barrel type electric resistance rotary furnace can reach given quenching temperatures and therefore quenching quality of the quenched parts is guaranteed.
Description
Technical field
The utility model relates to a kind of anti-blocking stopper rod, but a kind of anti-blocking stopper rod of inclined drum type resistance rotary furnace bell escape pipe particularly.
Background technology
Our company applied for " but bell of inclined drum type resistance rotary furnace " patent on September 14th, 2011, and the patent No. is ZL201120343698.9.This patent has obtained following beneficial effect really after but many inclined drum type resistance rotary furnaces of our company use: " cylinder of bell is not subject to the impact of thermal-flame and is out of shape and damages.Bell makes the fire door dissipation of heat less and the furnace heat loss is less.The low convenient operation personnel operation of rotating handles temperature.But " above-mentioned patented technology planar defect in the presence of finding after many inclined drum type resistance rotary furnaces uses of our company.Under normal operation, but the inner bag of inclined drum type resistance rotary furnace when uninterrupted slow rotation owing to when carburizing and quenching, constantly add kerosene, just have during the kerosene burning a certain amount of hot waste gas of carrying flue dust and dust secretly from the bell escape pipe out.When the hot waste gas of carrying flue dust and dust secretly passes through the bell escape pipe, have a small amount of flue dust and dust and be adsorbed on the bell escape pipe tube wall.The flue dust that accumulates on the working time longer bell escape pipe tube wall and dust are just more much thicker, the bell escape pipe can be stopped up at last.But the waste gas after the bell escape pipe stops up in the inclined drum type resistance rotary furnace just can not arranged, but the oil that adds in the inclined drum type resistance rotary furnace so just can not normally fully burn, but the quenching part in the inclined drum type resistance rotary furnace does not just reach the hardening heat of setting, and this will have a strong impact on the quenching quality of quenching part.
Summary of the invention
But the purpose of this utility model provides a kind of anti-blocking stopper rod of inclined drum type resistance rotary furnace bell escape pipe.This anti-blocking stopper rod can prevent that the bell escape pipe from stopping up.But the kerosene that adds in the inclined drum type resistance rotary furnace so just can normally fully burn, but the quenching part in the inclined drum type resistance rotary furnace just can reach the hardening heat of setting, just can guarantee the quenching quality of quenching part.
The technical solution of the utility model is: but a kind of anti-blocking stopper rod of inclined drum type resistance rotary furnace bell escape pipe.But inclined drum type resistance rotary furnace includes body of heater.Be contained in the middle inner bag of body of heater.The cylindrical shape bell that is connected with inner bag.Be designed with cylindrical shape bell escape pipe in the middle of the cylindrical shape bell.Be characterized in: install an anti-blocking stopper rod in bell escape pipe intermediate active.All stretch out outside the port of bell escape pipe two ends at these anti-blocking stopper rod two ends.Anti-blocking stopper rod stretches out the knee that the port outer anti-blocking stopper rod bending in two ends in bell escape pipe two ends goes out to have certain angle can not skid off anti-blocking stopper rod from the bell escape pipe.
Described anti-blocking stopper rod is made by high temperature resistant round stock.
The diameter of described anti-blocking stopper rod is no more than 1/3 of bell escape pipe internal diameter.
Operation principle of the present utility model is: but inclined drum type resistance rotary furnace when work, but the inner bag of inclined drum type resistance rotary furnace slow rotation continuously.But but the bell that there is a bell escape pipe centre that is connected with the inclined drum type resistance rotary furnace inner bag is also with the inner bag of inclined drum type resistance rotary furnace together slow rotation continuously.When the bell escape pipe rotated, the anti-blocking stopper rod in the middle of the bell escape pipe also constantly rotated or stirs in the bell escape pipe.In the situation that anti-blocking stopper rod constantly rotates or stirs, flue dust and the dust of process bell escape pipe just can not be adsorbed on the bell escape pipe tube wall.But these flue dust and dust can together be discharged outside the inclined drum type resistance rotary furnace body of heater with hot waste gas.Anti-blocking like this stopper rod has just realized making the bell escape pipe not by the purpose of flue dust and dust obstruction.
But the utility model has the advantages that the anti-blocking stopper rod that a kind of inclined drum type resistance rotary furnace bell escape pipe is provided.This anti-blocking stopper rod can prevent that the bell escape pipe from stopping up.But the kerosene that adds in the inclined drum type resistance rotary furnace so just can normally fully burn, but the quenching part in the inclined drum type resistance rotary furnace just can reach the hardening heat of setting, just can guarantee the quenching quality of quenching part.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, body of heater, 2, the Inner courage, 3, the cylinder bell, 4, the bell escape pipe, 5, anti-blocking stopper rod, 6, knee.
The specific embodiment
Embodiment as shown in Figure 1 is as follows: but a kind of anti-blocking stopper rod of inclined drum type resistance rotary furnace bell escape pipe.But inclined drum type resistance rotary furnace includes body of heater 1.Be contained in the inner bag 2 of body of heater 1 centre.The cylindrical shape bell 3 that is connected with inner bag 2.Be designed with cylindrical shape bell escape pipe 4 in the middle of the cylindrical shape bell 3.Be characterized in: install an anti-blocking stopper rod 5 in bell escape pipe 4 intermediate active.All stretch out outside the bell escape pipe 4 two ends ports at these anti-blocking stopper rod 5 two ends.Anti-blocking stopper rod 5 stretches out the knee 6 that the outer anti-blocking stopper rod bending in two ends of bell escape pipe 4 two ends ports goes out to have certain angle can not skid off anti-blocking stopper rod 5 from bell escape pipe 4.
Described anti-blocking stopper rod 5 is made by high temperature resistant round stock.
The diameter of described anti-blocking stopper rod 5 is no more than 1/3 of bell escape pipe internal diameter.
