Description

Technical Field

[0001] The utility model belongs to the technical field of industrial furnaces, and in particular relates to an industrial furnace which is convenient for cleaning fuel slag. Background Art

[0002] Industrial furnaces are divided into two categories according to the heating method: one is the flame furnace (or fuel furnace), which uses the heat from the combustion of solid, liquid or gaseous fuel in the furnace to heat the workpiece; the second is the electric furnace, which converts electrical energy into heat for heating in the furnace.

[0003] Industrial furnaces are divided into two categories according to the thermal system: one is the intermittent furnace, also known as the periodic furnace, which is characterized by the fact that the furnace is not divided into temperature zones, the furnace is produced in one or two shifts, and the furnace temperature changes in each heating cycle, such as various chamber furnaces, trolley furnaces, pit furnaces, bell furnaces, etc.; the other is the continuous furnace, which is characterized by the fact that the furnace is divided into temperature zones, generally consisting of three zones: preheating, heating (high temperature), and uniform heating (insulation). The furnace is produced continuously in three shifts. During the heating process of the industrial furnace, the temperature in each zone can be considered to be constant, such as two-stage or three-stage continuous heating furnaces, pusher heating furnaces and heat treatment furnaces, ring furnaces, walking beam furnaces, vibrating bottom furnaces, cupolas and lime kilns.

[0004] At present, the prior art, Chinese utility model patent CN213984596U discloses an industrial furnace that is convenient for cleaning combustion slag. The gravity sensor and the display structure are electrically connected. The weight of the slag in the slag collecting box can be monitored in real time through the gravity sensor and the display structure. When the slag in the slag collecting box reaches a certain weight, the staff cleans it. The electric rotating shaft and the infrared sensor are electrically connected. When the slag collecting box is pulled out, the slag receiving box is sensed by the infrared sensor, and then the movable plate is opened under the action of the electric rotating shaft to send the slag to the slag receiving box, which is convenient for cleaning the waste slag generated after the combustion of the industrial furnace, reducing the difficulty of work, and the position and size between the slide rail and the pulley are adapted to reduce manpower and material resources, and improve the efficiency of cleaning; through the setting of the heat-proof pad, the staff can be prevented from being scalded during cleaning, and the safety of use is improved; through the setting of the air filter, the flue gas is filtered to prevent environmental pollution and improve the quality of the environment. The air filter is a detachable structure, which is convenient for replacing or cleaning the air filter and increasing the practicality of the device.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0029] like Figure 1 As shown, it is a schematic diagram of the structure of an industrial furnace for convenient cleaning of fuel slag in a preferred embodiment of the utility model. The industrial furnace for convenient cleaning of fuel slag in this embodiment includes a slag collecting drawer 200 installed near the bottom of the industrial furnace body 100, the slag collecting drawer 200 is plugged into the industrial furnace body 100, and a smoke exhaust pipe 101 for exhausting smoke is provided at the upper end of the industrial furnace body 100. A pull-out handle 201 is fixedly connected to the outer wall of the slag collecting drawer 200. In this embodiment, the slag collecting drawer 200 is used to receive the slag, and the slag collecting drawer 200 can be pulled outward by the pull-out handle 201.

[0030] like Figure 2As shown, it is a schematic diagram of the slag collecting drawer structure in the present embodiment, the inner sides of the slag collecting drawer 200 and the inner wall away from the pull-out handle 201 are fixedly connected with guide inclined blocks 202 inclined toward the center of the slag collecting drawer 200, the center of the slag collecting drawer 200 is rotatably connected with a slag holding plate 203, and the outer wall of the slag collecting drawer 200 located below the pull-out handle 201 is provided with a discharge inclined port 204. In the present embodiment, the slag can be gathered on the slag holding plate 203 by the provision of the guide inclined blocks 202, and the slag can be discharged outwardly through the discharge inclined port 204 by rotating one end of the slag holding plate 203 close to the discharge inclined port 204, thereby the slag can be cleaned without first pulling out the slag collecting drawer 200.
