The strip fan plate draws the smoke into the circular plate, and the elastic wire mesh in the circular plate blocks the smoke dust.

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] See also Figures 1-8 One embodiment of the present invention is: a regenerative trolley furnace with a uniform heating function, comprising a regenerative furnace 1, wherein inverted L-shaped slide rails are respectively provided on the front and back sides of the inner wall of the regenerative furnace 1, and resistance heating plates 2 are respectively fixedly installed on the front and back sides of the inner wall of the regenerative furnace 1, and the two resistance heating plates 2 are located above the two inverted L-shaped slide rails of the regenerative furnace 1. A gate assembly 3 is fixedly installed on the right side of the regenerative furnace 1, and a carrier 4 is slidably installed on the outer wall of the two inverted L-shaped slide rails of the regenerative furnace 1;

[0031] The middle of the top surface of the regenerative furnace 1 is penetrated and fixedly installed with an arc shell 5, and oil holes are respectively opened on the left and right sides of the arc shell 5. A circular plate 8 is fixed to the bottom surface of the arc shell 5, and an elastic wire mesh 9 is fixedly installed on the bottom of the inner wall of the circular plate 8. A U-shaped frame 10 is fixed on the left side of the top surface of the regenerative furnace 1, and a motor 11 is fixedly installed in the middle of the top surface of the U-shaped frame 10. Round rods 12 are penetrated and rotatably installed on the left and right sides of the inner wall of the arc shell 5. The left side of the round rod 12 is fixedly connected to the right side of the rotating shaft of the motor 11. Round groove blocks 13 are respectively fixed on both sides of the outer wall of the round rod 12. The outer walls of the two round groove blocks 13 are respectively opened with four notches, and the four grooves of the two round groove blocks 13 The inner wall of the opening is respectively fixedly mounted with strip fan plates 14, and the four strip fan plates 14 are located above the elastic wire mesh 9. The strip fan plates 14 draw the smoke into the circular plate 8, and the elastic wire mesh 9 in the circular plate 8 blocks smoke and dust. The strip fan plates 14 fan the filtered smoke into the heat storage furnace 1 again. Under the action of the residual heat of the smoke, the elastic wire mesh 9 will be heated, and the elastic wire mesh 9 heats the workpiece on the carrier 4. The strip fan plates 14 fan the smoke in the heat storage furnace 1, allowing the residual heat of the smoke to evenly heat the workpiece, thereby avoiding the problem that when the regenerative trolley furnace is in use, the residual heat of the smoke is difficult to evenly heat the workpiece, resulting in poor waste heat utilization of the equipment.

[0032] Anti-blocking hole components are set on both sides of the outer wall of the round rod 12, and the anti-blocking hole components include two arc groove rings 15, which are respectively fixed on both sides of the outer wall of the round rod 12, and the two arc groove rings 15 are located on the side of the two circular groove blocks 13 away from each other. The outer walls of the two arc groove rings 15 are respectively provided with three arc grooves, and the outer walls of the two arc groove rings 15 are respectively embedded with three elastic arc plates 16, and each elastic arc plate 16 is fixed with a short column 17 on the side away from the two arc groove rings 15. The elastic wire mesh 9 is on the movement trajectory of each short column 17, and the short column 17 is against the top of the elastic wire mesh 9. The elastic wire mesh 9 will be deformed, causing the elastic wire mesh 9 to be reciprocally concave, and the smoke and dust in the mesh of the elastic wire mesh 9 will be shaken off, so as to avoid the smoke and dust in the flue gas being blocked in the elastic wire mesh 9 when the heat storage trolley furnace is in use, resulting in poor smoking and smoke exhaust effects of the equipment.

[0033] During use, the staff places the workpiece on the carrier 4, pushes the carrier 4 into the heat storage furnace 1, starts the gate assembly 3, the gate in the gate assembly 3 moves downward, closes the heat storage furnace 1, starts the resistance heating plate 2 on the heat storage furnace 1, and the resistance heating plate 2 heats the workpiece on the carrier 4. Since the smoke generated by the heating of the workpiece carries a part of the heat, the smoke generated by the heating of the workpiece is easy to be lost during the process of the equipment heating the workpiece. At this time, the heat storage furnace 1 supports the arc shell 5, and the heat storage furnace 1 supports the U-shaped frame 10. The motor 11 on the U-shaped frame 10 is started, and the shaft of the motor 11 starts to rotate forward. The shaft of the motor 11 drives the round rod 12 to rotate forward. The round rod 12 rotates forward in the arc shell 5. The round rod 12 drives the circular groove block 13 to rotate forward. The circular groove block 13 drives the strip fan plate 14 to rotate forward. During the process of the equipment heating the workpiece , under the action of air pressure, the flue gas generated when the workpiece is heated by the resistance heating plate 2 will float upward. During the forward rotation of the fan plate 14, the fan plate 14 will draw the flue gas into the circular plate 8. The elastic wire mesh 9 in the circular plate 8 will block the smoke and dust. The fan plate 14 will fan the filtered flue gas into the heat storage furnace 1 again. Under the action of the residual heat of the flue gas, the elastic wire mesh 9 will be heated, and the elastic wire mesh 9 heats the workpiece on the carrier 4. At the same time, under the fanning of the fan plate 14, the flue gas circulates in the heat storage furnace 1, so that the fan plate 14 fans the flue gas in the heat storage furnace 1, allowing the residual heat of the flue gas to evenly heat the workpiece, preventing the equipment from being used. The residual heat of the flue gas is difficult to heat the workpiece evenly, thereby avoiding the problem of poor waste heat utilization of the equipment caused by the residual heat of the flue gas being difficult to heat the workpiece evenly when the heat storage trolley furnace is in use.

[0034] While the rotating shaft of the motor 11 drives the round rod 12 to rotate forward, the round rod 12 drives the arc groove ring 15 to rotate forward, the arc groove ring 15 drives the elastic arc plate 16 to rotate forward, and the elastic arc plate 16 drives the short column 17 to rotate forward. The short column 17 contacts the elastic wire mesh 9 during the forward rotation. Under the action of the extrusion force, the short column 17 is pressed against the top of the elastic wire mesh 9, and the elastic wire mesh 9 will be deformed, causing the elastic wire mesh 9 to be reciprocatingly concave, shaking off the smoke and dust in the mesh of the elastic wire mesh 9, preventing the mesh of the elastic wire mesh 9 from being clogged with smoke and dust when the equipment is in use, thereby avoiding the problem of smoke and dust in the flue gas being clogged in the elastic wire mesh 9 when the regenerative trolley furnace is in use, causing the equipment to smoke and have poor smoke exhaust effects.

[0035] See also Figures 1-8On the basis of the above embodiment, in another embodiment of the present invention, the three arc groove inner walls of the two arc groove rings 15 are provided with a smoke and dust prevention device 6, which includes six short rods 61, two round shells 62, two sealing rings 63 and two convex shells 64. The six short rods 61 are fixedly mounted on the three arc groove inner walls of the two arc groove rings 15, respectively. The two round shells 62 are fixed on the left and right sides of the inner wall of the arc shell 5. A circular opening is opened on the side where the two round shells 62 are close to each other. The two sealing rings 63 are fixed on the two On the inner wall of the circular shell 62, two convex shells 64 are fixed on the side of each short rod 61 away from each other, and the outer walls of the two convex shells 64 are rotatably connected to the inner wall of the circular shell 62. The outer walls of the two convex shells 64 are in rotational contact with the inner walls of the two sealing rings 63. During the forward rotation of the convex shell 64, the sealing ring 63 limits the gap of the convex shell 64, preventing smoke and dust from contacting the gap between the round rod 12 and the arc shell 5, thereby preventing smoke and dust in the flue gas from adhering to the gap between the round rod 12 and the arc shell 5 when the regenerative trolley furnace is in use, causing the equipment to jam.

[0036] The smoke and dust prevention device 6 also includes two ring plates 65, several connecting columns 66 and several long plates 67. The two ring plates 65 are fixed in the middle of the outer walls of the two convex shells 64. Several connecting columns 66 pass through and are fixed on the side where the two ring plates 65 are close to each other. Several long plates 67 are respectively fixed on the outer wall of each connecting column 66. Several long plates 67 are respectively located on the side where the two ring plates 65 are away from each other. The long plates 67 fans the smoke accumulated on the edge to the fan plate 14, so that smoke will not accumulate on the edge of the arc shell 5, thereby avoiding the accumulation of smoke on the edge of the arc shell 5 when the regenerative trolley furnace is in use, resulting in poor effect of circulating smoke waste heat in the equipment.

[0037] The inner wall of the smoke and dust prevention device 6 is provided with an anti-stuck device 7, which includes four cylinders 71, four springs 72, four slide rods 73, two ring abutment plates 74 and two asbestos rings 75. The four cylinders 71 are respectively fixed on the inner walls of the two convex shells 64, the four springs 72 are respectively fixed on the inner wall of each cylinder 71, the four slide rods 73 are fixed on one end of each spring 72 away from each cylinder 71, the outer wall of the four slide rods 73 is slidably connected to the inner wall of each cylinder 71, and the two ring abutment plates 74 are fixed on each At one end of the sliding rod 73 away from each other, two asbestos rings 75 are fixed on the side of the two ring support plates 74 away from each other. The two asbestos rings 75 are respectively located below the two oil holes of the arc shell 5. The sides of the two asbestos rings 75 away from each other are in rotational contact with the inner wall of the arc shell 5. Under the elastic force of the spring 72, the asbestos ring 75 rotates against the arc shell 5, allowing the asbestos ring 75 to apply lubricating oil to the arc shell 5, thereby avoiding friction between the round rod 12 and the arc shell 5 when the regenerative trolley furnace is in use, causing unstable operation of the equipment.

[0038] The anti-stuck device 7 also includes four T-shaped plates 76, four arc-shaped spring pieces 77 and four scrapers 78. The four T-shaped plates 76 are respectively fixed to the side of the two ring-type plates 74 away from each other. The four T-shaped plates 76 are respectively located above and below the round rod 12. The four arc-shaped spring pieces 77 are fixed on one side of each T-shaped plate 76. The four scrapers 78 are fixed on the side of each arc-shaped spring piece 77 away from each T-shaped plate 76. The four T-shaped plates 76 are respectively located inside the two asbestos rings 75. The arc shell 5 is on the movement trajectory of the four scrapers 78. Under the elastic force of the arc-shaped spring pieces 77, the scrapers 78 rotate against the arc shell 5, allowing the scrapers 78 to evenly scrape the lubricating oil on the arc shell 5, thereby avoiding uneven application of the lubricating oil when the regenerative trolley furnace is in use, resulting in poor rotation of the equipment.

[0039] When the round rod 12 drives the arc groove ring 15 to rotate forward, the smoke in the flue gas will adhere to the gap between the round rod 12 and the arc shell 5. Long-term use will cause the round rod 12 to rotate unsmoothly. At this time, the arc groove ring 15 drives the short rod 61 to rotate forward, and the short rod 61 drives the convex shell 64 to rotate forward. The convex shell 64 rotates forward in the round shell 62, and the round shell 62 supports the sealing ring 63, so that during the forward rotation of the convex shell 64, the sealing ring 63 limits the gap of the convex shell 64, blocking the smoke from contacting the gap between the round rod 12 and the arc shell 5, preventing the smoke from adhering to the gap between the round rod 12 and the arc shell 5 during the use of the equipment, thereby avoiding the problem that the smoke in the flue gas adheres to the gap between the round rod 12 and the arc shell 5 when the regenerative trolley furnace is in use, causing the equipment to jam.

[0040] While the short rod 61 drives the convex shell 64 to rotate forward, the convex shell 64 drives the ring plate 65 to rotate forward, the ring plate 65 drives the connecting column 66 to rotate forward, and the connecting column 66 drives the long plate 67 to rotate forward. During the forward rotation of the long plate 67, the long plate 67 fans the flue gas accumulated on the inner edge of the arc shell 5, so that the long plate 67 fans the flue gas accumulated on the edge onto the fan plate 14, so that the edge of the arc shell 5 will not be accumulated with flue gas, and the edge of the arc shell 5 is prevented from being accumulated with flue gas during the use of the equipment, thereby avoiding the problem of poor effect of circulating flue gas waste heat caused by the accumulation of flue gas on the edge of the heat storage trolley furnace when it is in use.

[0041] When locking sill 75 and locking sill 77 are located at the bottom, the locking sill 77 will be in the state of being firmly fixed on the locking sill 71, so that lock sill 77 can be locked in the state of being firmly fixed on the locking sill 71.

[0042] When the sliding rod 73 drives the annular plate 74 to rotate forward, the annular plate 74 drives the T-shaped plate 76 to rotate forward, the T-shaped plate 76 drives the arc spring piece 77 to rotate forward, and the arc spring piece 77 drives the scraper 78 to rotate forward. Under the elastic force of the arc spring piece 77, the scraper 78 is pressed against the arc shell 5 and rotates, allowing the scraper 78 to evenly scrape the lubricating oil on the arc shell 5, preventing the equipment from being unevenly smeared with lubricating oil when in use, thereby avoiding the problem of poor rotation effect of the equipment caused by uneven smearing of lubricating oil when the regenerative trolley furnace is in use.

[0043] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
