[0033] In the embodiment of the present disclosure, the interior of the preheating seat 101 is divided into two upper and lower cavities by the partition seat 201. The upper cavity is the preparation cavity 1011, and the lower cavity is the preheating cavity 1012. The feeding pipeline 104 is arranged on the side of the preheating cavity 1012, and the furnace charge in the preheating cavity 1012 can be transported to the heating furnace through a screw conveyor. During use, the furnace charge can be stored in the preparation cavity 1011, so that it can be added to the interior of the preheating cavity 1012 for preheating when needed. A heating device is provided at the bottom of the preheating cavity 1012, and an exhaust gas heating channel 10121 is provided inside the wall of the preheating seat 101 located at the preheating cavity 1012, and the exhaust gas heating channel 10121 is respectively connected to the air intake pipe 102 and the exhaust pipe 103, so that the exhaust gas of the heating furnace can be discharged through the air intake pipe 102 and the exhaust pipe 103. The pipe 102 enters into the interior of the exhaust gas heating channel 10121, and the exhaust gas heating channel 10121 can be discharged through the exhaust pipe 103. The preheating chamber 1012 can realize the preheating operation of the charge. The charge can be preheated by the heating device at the bottom of the preheating chamber 1012, and the high-temperature exhaust gas of the heating furnace can flow through the air intake pipe 102, the exhaust gas heating channel 10121 and the exhaust pipe 103 in sequence when discharged, so that the exhaust gas can pass through the preheating chamber 1012 in a circular manner when discharged, and the charge is auxiliary preheated by the high temperature of the exhaust gas, and the waste heat of the exhaust gas is recycled, thereby reducing the energy loss during the preheating of the charge. The preheating chamber 1012 is always in a closed state, and the heat inside the preheating chamber 1012 will not be lost through the preparation chamber 1011, and the preheating of the charge is stable and fast.

[0034] In the embodiment of the present disclosure, the partition seat 201 is a cylindrical seat body, and a material distribution chamber 2013 is provided inside the partition seat 201. The bottom of the material distribution chamber 2013 is a closed design, and the top of the material distribution chamber 2013 is an open design. The push plate 202 is inserted into the inside of the material distribution chamber 2013. During use, the partition assembly can realize the function of adding the furnace charge inside the material preparation chamber 1011 to the inside of the preheating chamber 1012 while maintaining the independent closure between the material preparation chamber 1011 and the preheating chamber 1012. When adding the furnace charge for preheating, the closed state of the preheating chamber 1012 will not be changed, thereby avoiding large temperature fluctuations inside the preheating chamber 1012 when adding the furnace charge. The preheating is stable. When the material distribution chamber 2013 is used, the material distribution chamber 2013 is opened. When the material distribution chamber 2013 is used with 2013 facing upward, the furnace charge inside the preparation chamber 1011 will automatically enter and fill the material distribution chamber 2013 under the action of gravity, preparing for the subsequent feeding into the preheating chamber 1012. When it is necessary to add furnace charge to the preheating chamber 1012 for preheating, it is only necessary to control the drive motor 4 to rotate forward. When the drive motor 4 rotates forward, it can drive the drive disk 301 to rotate synchronously. Since the synchronization block 302 is timely inserted into the synchronization slot 2012 of the first control slot 211 when the material distribution chamber 2013 is used with 2013 facing upward, the drive disk 301 and the partition seat 201 are used as a whole at this time, and their movement state is always the same, so that when the drive disk 301 rotates forward, it can drive the partition seat 20 1 Synchronous rotation changes the use direction of the material distribution chamber 2013. When the driving disk 301 and the partition seat 201 rotate 180 degrees, the material distribution chamber 2013 will be used downward, so that the furnace charge inside the material distribution chamber 2013 is added to the inside of the preheating chamber 1012, realizing a single filling operation, which is convenient and flexible to use. The cross-sectional shape of the damping positioning block 205 on the side facing the partition seat 201 is a triangular design, and a positioning top spring 2051 is provided inside the damping positioning block 205. The two ends of the positioning top spring 2051 are respectively against the inside of the damping positioning block 205 and the inside of the preheating seat 101. Under the action of the positioning top spring 2051, the damping positioning block 205 is against the outside of the seat body of the partition seat 201. When the opening of the material distribution chamber 2013 is facing upward, the angle between the damping positioning block 205 and the first control groove 211 is one hundred and eighty degrees, and the elastic force of the positioning top spring 2051 is greater than the elastic force of the synchronous top spring 3021. During this process, although the damping positioning block 205 will be inserted into the ejection groove 2011 of the second control groove 212 under the action of the positioning top spring 2051, since the block cross-section of one side of the damping positioning block 205 is triangular, when the partition seat 201 rotates, the block bevel of the damping positioning block 205 and the groove bevel of the ejection groove 2011 will squeeze each other, causing the damping positioning block 205 to move away, which will not hinder the rotation of the partition seat 201 and is stable to use.

[0035] In the embodiment of the present disclosure, a control groove is provided on the side of the separator seat 201, and the control groove is composed of an ejection groove 2011 with a trapezoidal cross-section and a synchronization groove 2012 with a rectangular cross-section. The top of the synchronization groove 2012 is connected to the bottom of the ejection groove 2011. There are two control grooves, which are the first control groove 211 and the second control groove 212. A synchronization top spring 3021 is provided inside the timely synchronization block 302. The two ends of the synchronization top spring 3021 are respectively against the interior of the timely synchronization block 302 and the interior of the driving disk 301. When the opening of the material distribution chamber 2013 is facing upward, under the action of the synchronization top spring 3021, the timely synchronization block 302 is inserted into the synchronization groove 2012 of the first control groove 211. In use, the separator component also has a pushing structure When filling the preheating chamber 1012, the push plate 202 can move toward the opening direction of the distribution chamber 2013, so that all the furnace charge in the distribution chamber 2013 is pushed into the preheating chamber 1012, so as to avoid the furnace charge being stuck in the distribution chamber 2013 and being unable to be filled normally. When the opening of the distribution chamber 2013 is rotated from upward to downward (that is, the partition seat 201 is rotated 180 degrees), the first control groove 211 and the damping positioning block 205 are aligned. Under the action of the positioning top spring 2051, the damping positioning block 205 can be inserted into the ejection groove 2011 of the first control groove 211, and the synchronous block 302 is pushed out of the synchronous groove 2012 of the first control groove 211 at the right time, so that the damping positioning block 205 can be The use state of the partition seat 201 is positioned by inserting it into the ejection groove 2011 of the first control groove 211, and then the driving disk 301 rotates independently, a driving gear 2031 is provided at one end of the driving shaft 203, and a driving rack 3011 is provided inside the driving disk 301, and the gear teeth of the driving gear 2031 and the driving rack 3011 are meshed for transmission. When the driving disk 301 rotates independently of the partition seat 201, the driving rack 3011 can drive the driving shaft 203 to rotate through the driving gear 2031, and when the driving shaft 203 rotates, it can drive the driving rod 204 to rotate through the gear set, and the driving shaft 203 and the driving rod 204 are synchronously connected by the gear set, and the rod body of the driving rod 204 is provided with a thread on the outside, and the driving rod 204 is driven by the rod The body thread is screwed on the inside of the push plate 202, and the driving rod 204 can drive the push plate 202 to move toward the opening direction of the distribution chamber 2013 through the rod body thread when rotating, so as to realize the operation of pushing the furnace charge inside the distribution chamber 2013 into the preheating chamber 1012 while maintaining the use angle of the partition seat 201. It is convenient and flexible to use, and with the rotation of the driving disk 301, the timely synchronization block 302 will move to the position of the second control groove 212, and under the action of the synchronization top spring 3021, the timely synchronization block 302 will be inserted into the synchronization groove 2012 of the second control groove 212 to prepare for the subsequent reset operation, with a high degree of automation. After completing a single filling and pushing operation, the partition assembly can be reset by controlling the reverse direction of the driving motor 4.The material dispensing chamber 2013 is restored to the open upward use state. After completing a single filling and pushing operation, the driving motor 4 is controlled to reverse and can drive the driving disc 301 to reverse synchronously. When the driving disc 301 reverses, the timely synchronization block 302 can drive the partition seat 201 to reverse through the synchronization groove 2012 of the second control groove 212. At this time, the damping positioning block 205 triggers the avoidance action again to escape from the inside of the ejection groove 2011 of the first control groove 211, which will not hinder the rotation of the partition seat 201. When the timely synchronization block 302 moves to the damping positioning block When the damping positioning block 205 is in the position of 205, under the action of the positioning top spring 2051, the damping positioning block 205 will be inserted into the ejection groove 2011 of the second control groove 212, and the timely synchronization block 302 will be pushed out of the synchronization groove 2012 of the second control groove 212. After that, the driving disk 301 will reverse alone and drive the push plate 202 to move and reset to the inside of the material distribution cavity 2013 through the cooperation of the driving rack 3011 and the driving gear 2031, until the timely synchronization block 302 moves to the position of the first control groove 211, and the synchronization top spring is pressed. Under the action of 3021, the synchronous block 302 is inserted into the synchronous groove 2012 of the first control groove 211 again, and then the driving disk 301 and the partition seat 201 form a whole again, and the partition seat 201 will follow the driving disk 301 to synchronously reverse and reset to prepare for the next filling. The whole process is fully automated, which simplifies the operation process and improves work efficiency. When the material distribution mechanism 2 is filling and resetting the preheating chamber 1012, the open part of the material distribution chamber 2013 will be rotated by the preheating seat 101 The inner wall blocks the preheating chamber 1012, so that the open part of the preheating chamber 1012 will not be connected to the material preparation chamber 1011 and the preheating chamber 1012 when the partition seat 201 rotates, avoiding large temperature fluctuations inside the preheating chamber 1012, and the use is stable. In addition, since the push plate 202 will block the open position of the material distribution chamber 2013 during the reset process of the partition assembly, the heat of the preheating chamber 1012 will not be hidden in the cavity of the material distribution chamber 2013 and escape, further reducing the heat loss of the preheating chamber 1012 when filling.

[0036] Specific usage and function of this embodiment: In the present invention, the charge can be stored inside the preparation chamber 1011, so that when needed, the charge can be added to the preheating chamber 1012 for preheating later through the partition assembly. The preheating chamber 1012 can realize the preheating operation of the charge, and the charge can be preheated by the heating device at the bottom of the preheating chamber 1012. The high-temperature exhaust gas of the heating furnace can flow through the air intake pipe 102, the exhaust gas heating channel 10121 and the exhaust pipe 103 in sequence when discharged, so that the exhaust gas can pass through the preheating chamber 1012 in a circumferential manner when discharged. The high temperature of the exhaust gas is used to assist in preheating the charge, and the waste heat of the exhaust gas is recycled, thereby reducing the energy loss during charge preheating. Cavity 1012 is always in a closed state, and the heat inside the preheating chamber 1012 will not be lost through the preparation chamber 1011. The partition component can realize the function of adding the furnace charge inside the preparation chamber 1011 to the preheating chamber 1012 while maintaining the independent closure between the preparation chamber 1011 and the preheating chamber 1012. When adding the furnace charge for preheating, the closed state of the preheating chamber 1012 will not be changed, thereby avoiding large temperature fluctuations inside the preheating chamber 1012 when adding the furnace charge, and the preheating is stable. When the distribution chamber 2013 is used upward, the furnace charge inside the preparation chamber 1011 will automatically enter and fill the distribution chamber 2013 under the action of gravity, preparing for the subsequent feeding into the preheating chamber 1012. 2 When adding charge inside for preheating, it is only necessary to control the driving motor 4 to rotate forward. When the driving motor 4 rotates forward, it can drive the driving disc 301 to rotate synchronously. Since the synchronous block 302 is inserted into the synchronous slot 2012 of the first control slot 211 when the material distribution chamber 2013 is used upward, the driving disc 301 and the partition seat 201 form a whole at this time, and their movement state is always the same. Therefore, when the driving disc 301 rotates forward, it can drive the partition seat 201 to rotate synchronously to change the use direction of the material distribution chamber 2013. After the driving disc 301 and the partition seat 201 rotate 180 degrees, the material distribution chamber 2013 will be used downward, so that the charge inside the material distribution chamber 2013 is added to the inside of the preheating chamber 1012, realizing a single The filling operation is convenient and flexible to use. In the process, although the damping positioning block 205 will be inserted into the ejection groove 2011 of the second control groove 212 under the action of the positioning top spring 2051, since the cross-section of the block on one side of the damping positioning block 205 is triangular, when the partition seat 201 rotates, the block bevel of the damping positioning block 205 and the groove bevel of the ejection groove 2011 will squeeze each other, so that the damping positioning block 205 moves to avoid, and will not hinder the rotation of the partition seat 201. The partition component also has a pushing structure. When filling the preheating chamber 1012, the pushing plate 202 can move toward the opening direction of the distribution chamber 2013, thereby pushing all the furnace charge in the distribution chamber 2013 into the preheating chamber 1012.In order to avoid the phenomenon that the charge is stuck in the inside of the material distribution chamber 2013 and cannot be filled normally, when the opening of the material distribution chamber 2013 is rotated from upward to downward (that is, the partition seat 201 is rotated 180 degrees), the first control groove 211 and the damping positioning block 205 are aligned, and under the action of the positioning top spring 2051, the damping positioning block 205 can be inserted into the inside of the ejection groove 2011 of the first control groove 211, and the synchronous block 302 is timely ejected from the synchronous groove 2012 of the first control groove 211, so that the damping positioning block 205 can be inserted into the inside of the ejection groove 2011 of the first control groove 211 to position the use state of the partition seat 201, and thereafter the driving disk 301 rotates alone, and the driving disk 301 is independent of the partition seat 201. When rotating, the driving rack 3011 can drive the driving shaft 203 to rotate through the driving gear 2031. When the driving shaft 203 rotates, it can drive the driving rod 204 to rotate through the gear set. When the driving rod 204 rotates, it can drive the pushing plate 202 to move toward the opening direction of the distribution chamber 2013 through the rod body thread, thereby achieving the operation of pushing the furnace charge inside the distribution chamber 2013 into the preheating chamber 1012 while maintaining the use angle of the partition seat 201. It is convenient and flexible to use, and with the rotation of the driving disk 301, the timely synchronization block 302 will move to the position of the second control groove 212, and under the action of the synchronization top spring 3021, the timely synchronization block 302 will be inserted into the synchronization groove 2012 of the second control groove 212 for subsequent After the single filling and pushing operation is completed, the partition assembly can be reset by controlling the driving motor 4 to reverse and restore the use state of the material distribution chamber 2013 with the opening facing upward. After the single filling and pushing operation is completed, the driving motor 4 can be controlled to reverse to drive the driving disk 301 to reverse synchronously. When the driving disk 301 reverses, the timely synchronization block 302 can drive the partition seat 201 to reverse through the synchronization groove 2012 of the second control groove 212. At this time, the damping positioning block 205 triggers the avoidance action again to escape from the inside of the ejection groove 2011 of the first control groove 211, and will not hinder the rotation of the partition seat 201. When the timely synchronization block 302 moves to the position of the damping positioning block 205, under the action of the positioning top spring 2051, the damping positioning block 20 5 will be inserted into the ejection groove 2011 of the second control groove 212, and the timely synchronous block 302 will be pushed out of the synchronous groove 2012 of the second control groove 212. After that, the driving disk 301 will reverse independently and drive the push plate 202 to move and reset to the inside of the material distribution chamber 2013 through the cooperation of the driving rack 3011 and the driving gear 2031, until the timely synchronous block 302 moves to the position of the first control groove 211, and under the action of the synchronous top spring 3021, the timely synchronous block 302 is inserted into the synchronous groove 2012 of the first control groove 211 again, and then the driving disk 301 and the partition seat 201 will form a whole again, and the partition seat 201 will follow the driving disk 301 to reverse and reset synchronously, so as to be used for the next filling.The whole process is fully automated. When the material dispensing mechanism 2 is filling and resetting the preheating chamber 1012, the open portion of the material dispensing chamber 2013 will be blocked by the inner wall of the preheating seat 101 when rotating, so that the open portion of the preheating chamber 1012 will not be connected to the material preparation chamber 1011 and the preheating chamber 1012 when the partition seat 201 rotates, thereby avoiding large temperature fluctuations inside the preheating chamber 1012. The use is stable, and because the push plate 202 will block the open position of the material dispensing chamber 2013 during the resetting process of the partition assembly, the heat of the preheating chamber 1012 will not be hidden inside the cavity of the material dispensing chamber 2013 and escape.

[0037] In another embodiment, a limiting groove is provided inside the preheating seat 101, and a limiting rod is provided outside the partition seat 201, which is inserted into the limiting groove. Under the action of the limiting groove, the maximum rotation angle of the partition seat 201 inside the preheating seat 101 is limited to one hundred and eighty degrees, so that the positioning of the partition seat 201 is accurate and the use is stable.
