Description

Technical Field

[0001] The utility model belongs to the technical field of trolley type resistance furnaces, and in particular relates to a full-fiber trolley type resistance tempering furnace. Background Art

[0002] The trolley type resistance furnace is a national standard energy-saving cycle operation furnace with an ultra-energy-saving structure and a fiber structure, which can save up to 60% of electricity. At present, the trolley type resistance furnace is mainly composed of the furnace body, heating device, hot air circulation device, trolley, trolley transmission device, furnace door, heat dissipation device, sealing device, temperature control and recording system, power system and other main parts. Among them, the trolley is one of the important parts of the trolley type resistance furnace, which undertakes the function of conveying workpieces, heating and transportation.

[0003] At present, the resistance tempering furnace in the prior art is basically a small-scale improvement on the old structure of the 1960s, and the structural design is unreasonable. For example, the sealing effect of the furnace body is not good, and when the quenched object is taken out, the sealed door needs to be opened, which causes the residual heat inside the furnace body to be discharged, resulting in heat waste. When the object is quenched, a large amount of smoke and debris will be generated. Although it is filtered through the filter, the long-term operation of the filter will cause the filter to be blocked, resulting in poor smoke exhaust effect.

[0004] Therefore, a full-fiber trolley-type resistance tempering furnace is needed to solve the problems in the prior art that when objects are taken out and cooled, heat discharge inside the furnace body causes waste and the smoke exhaust effect is poor. Utility Model Content

[0007] It should be noted that the cleaning mechanism includes an exhaust fan, which is installed on the inner wall of the exhaust duct and fits the inner wall of the furnace body. A rotating rod is fixed to the rear end of the driving shaft of the exhaust fan, and a brush plate is fixed to the top end of the rotating rod.

[0008] The cleaning mechanism also includes a filter screen, which is fixed to the top of the inner wall of the air outlet pipe.

[0009] It is further worth noting that the brush plate fits the surface of the filter screen.

[0010] It should be further explained that a C-shaped sealing groove is provided at the front end of the inner wall of the furnace body, and the sealing member is in contact with the inner wall of the sealing groove.

DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the embodiments.

[0022] See also Figure 1-4 The utility model provides a full-fiber trolley-type resistance tempering furnace, comprising a furnace body 1, heating elements 2 are fixedly installed on both sides of the outer wall of the furnace body 1, heating fans 3 are installed on both sides of the inner wall of the furnace body 1, two symmetrical limiting slide grooves 10 are provided at the bottom end of the inner wall of the furnace body 1, and limiting sliders 9 are slidably installed on the inner walls of the limiting slide grooves 10, and a placing plate 4 is fixed to the top of the limiting slider 9, a first sealing door 6 is fixed to the top of the placing plate 4, a heat conducting plate 5 is fixed to the middle of the top of the placing plate 4, a second sealing door 8 is fixed to the top of the inner side of the placing plate 4, a sealing member 7 is fixed to the side of the first sealing door 6 close to the furnace body 1, an air outlet pipe 13 is installed at the center of the top of the furnace body 1, and a cleaning mechanism 14 is provided on the inner wall of the air outlet pipe 13.

[0023] During the quenching process of the furnace body 1, a large amount of smoke and debris will be generated. By starting the exhaust fan 141, it can drive the rotating rod 142 to rotate, and at the same time, it can also draw the smoke to be discharged from the inner wall of the furnace body 1. At the same time, it can also drive the brush plate 143 to rotate, so as to clean the debris on the surface of the filter 144.

[0024] Further as Figure 1 , Figure 2 , Figure 3 As shown, it is worth to explain in detail that the cleaning mechanism 14 includes an exhaust fan 141, which is installed on the inner wall of the exhaust duct 13 and fits with the inner wall of the furnace body 1, and a rotating rod 142 is fixed to the rear end of the driving shaft of the exhaust fan 141, and a brush plate 143 is fixed to the top end of the rotating rod 142;

[0025] The cleaning mechanism 14 further includes a filter screen 144 , which is fixed to the top of the inner wall of the air outlet pipe 13 .

[0026] By starting the exhaust fan 141, the smoke generated by quenching the inner wall of the furnace body 1 can be extracted. At the same time, when the exhaust fan 141 is rotated, it can drive the rotating rod 142 to rotate, thereby driving the brush plate 143 to rotate, and further cleaning the debris generated by quenching on the surface of the filter 144.

[0027] Further Figure 3 As shown, it is worth explaining in detail that the brush plate 143 is in contact with the surface of the filter screen 144 .

[0028] This scheme has the following working process: first, the quenching object is placed on the surface of the heat conduction plate 5, and then the heating element 2 and the heating fan 3 are started to quench the object. At the same time, when the first sealing door 6 is closed, the sealing member 7 is fitted with the sealing groove 15, so that the furnace body 1 can be further sealed, and a large amount of smoke will be generated during quenching. By starting the exhaust fan 141, the smoke generated by quenching on the inner wall of the furnace body 1 can be discharged, and at the same time, the debris on the surface of the smoke can be filtered through the filter 144, and when the exhaust fan 141 is rotated, it can drive the brush plate 143 to rotate, and then drive the brush plate 143 to rotate, thereby cleaning the debris attached to the surface of the filter 144, thereby avoiding clogging of the filter 144.

[0029] According to the above working process, it can be known that: when taking out the quenched object, in order to preserve the heat of the inner wall of the furnace body 1, when the placement plate 4 is limitedly slid, it can drive the heat conduction plate 5 to slide, so that the quenched object can be pulled out of the inner wall of the furnace body 1, so that it can be cooled down. At the same time, when the placement plate 4 is pulled out of the inner wall of the furnace body 1, it can drive the second sealing door 8 on the surface of the placement plate 4 to further seal the furnace body 1, so that when the object is pulled out for cooling, the furnace body 1 can also be sealed, thereby further preserving the heat inside the furnace body 1.

[0030] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth to explain in detail that a C-shaped sealing groove 15 is opened at the front end of the inner wall of the furnace body 1 , and the sealing member 7 is in contact with the inner wall of the sealing groove 15 .

[0031] The sealing member 7 can mainly seal the sealing groove 15 , thereby further sealing the furnace body 1 , thereby maintaining the heat of the inner wall of the furnace body 1 .

[0032] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth explaining in detail that a plurality of brackets 11 are fixed to the bottom end of the first sealing door 6 , and movable wheels 12 are rotatably mounted on the bottom ends of the brackets 11 .

[0033] The movable wheel 12 can mainly drive the first sealing door 6 to perform supporting activities.

[0034] Further Figure 1 , Figure 2 , Figure 3 As shown, it is worth to explain in detail that a plurality of mounting frames 16 distributed in parallel are fixed at both ends of the bottom of the furnace body 1 .

[0035] In summary: by starting the exhaust fan 141, the smoke generated by quenching the inner wall of the furnace body 1 can be extracted, and at the same time, when the exhaust fan 141 is rotated, it can drive the rotating rod 142 to rotate, thereby driving the brush plate 143 to rotate, and further cleaning the debris generated by quenching on the surface of the filter 144.

[0036] The heating fan 3 and the exhaust fan 141 can be purchased on the market. The heating fan 3 and the exhaust fan 141 are equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so they are not repeated in the specification.
