Description

Technical Field

[0001] The invention relates to the technical field of furnace charge preheating, and in particular to a furnace charge preheating device with an auxiliary structure. Background Art

[0002] As the name suggests, the charge preheating device is a device for heating the charge. When the preheated charge enters the reaction stage, it has a certain amount of heat itself, which can reach the activation energy required for the reaction more quickly, accelerate the reaction rate, and thus improve the efficiency of the entire production process.

[0003] Although the existing charge preheating device can vibrate and flatten the charge when heating it, it cannot turn it over, which affects the heating efficiency of the charge, and the residue cannot be cleaned through the charge flattening structure; the existing device cannot assist in conveying the charge when vibrating and flattening it, and has poor structural performance.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a charge preheating device with an auxiliary structure is provided, in order to achieve a more practical purpose. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a charge preheating device with an auxiliary structure to solve the problem that the existing charge preheating device can vibrate and flatten the charge when heating the charge, but cannot turn it over, which affects the heating efficiency of the charge and cannot clean the residue through the charge flattening structure; the existing device cannot assist in conveying the charge when vibrating and flattening the charge, and has poor structural properties.

[0006] The present invention provides a charge preheating device with an auxiliary structure, specifically comprising: a support block; there are two support blocks in total, both of which are placed on the ground, two spring rods are fixed to the top surface of each support block, a first sliding block is fixed to the protruding end of each spring rod, a first sliding seat is slid on each first sliding block, four first sliding seats are fixed on the containing seat, and a spiral spring for resetting the containing seat to the right is sleeved on each first sliding seat; a cover body is fixed on the top of the containing seat, and a force-bearing block with a concave structure is fixed on the bottom end surface of the containing seat; a first rotating shaft is rotated on the two support blocks, a first motor is fixed on a front support block, and the output shaft of the first motor is fixed on the first rotating shaft; a toggle block is welded on the first rotating shaft, and when the first rotating shaft rotates, the toggle block elastically contacts with the bottom end surface of the inner wall of the force-bearing block; a protrusion is welded on the right end surface of the inner wall of the force-bearing block, and the protrusion is a semi-cylindrical structure, and when the first rotating shaft rotates, the toggle block elastically contacts with the protrusion.

[0007] Further, a heating component is installed on the cover body. The heating component is composed of a first sliding frame, a second sliding block, a combustion tube, a first threaded rod, and a second electric motor. A first sliding frame is fixed to the top end face of the inner wall of the cover body. A second sliding block slides on the first sliding frame. Two combustion tubes are fixed to the bottom of the second sliding block. Both of the two combustion tubes are connected to the gas supply pipeline.

[0008] Further, a first threaded rod is rotatably installed on the first sliding frame. The first threaded rod is threadedly connected to the second sliding block. A second electric motor is fixed to the left end face of the first sliding frame. The output shaft of the second electric motor is fixed to the first threaded rod.

[0009] Further, an auxiliary component is installed on the second sliding block. The auxiliary component is composed of a first mounting block, a first turning rod, a second sliding frame, a second mounting block, a second turning rod, and an electric cylinder. A first mounting block in the shape of a rectangular block is fixed to the bottom end face of the second sliding block. The bottom end face of the first mounting block is welded with first turning rods in a linear array. The first turning rods are cylindrical rod-shaped structures. The bottom end faces of the first turning rods welded in a linear array are all in contact with the bottom end face of the inner wall of the placing seat.

[0010] Further, a second sliding frame is fixed to the bottom end face of the second sliding block. A second mounting block slides on the second sliding frame. The bottom end face of the second mounting block is welded with second turning rods in a linear array. The second turning rods are cylindrical rod-shaped structures. The bottom end faces of the second turning rods welded in a linear array are all in contact with the bottom end face of the inner wall of the placing seat.

[0011] Further, an electric cylinder is fixed to the second mounting block. The extending end of the electric cylinder is fixed to the second sliding frame. When the electric cylinder contracts completely, the second turning rods are aligned with the first turning rods. When the electric cylinder extends, the second turning rods and the first turning rods are staggered. The gap between two adjacent first turning rods is smaller than the diameter of the first turning rod. The gap between two adjacent second turning rods is smaller than the diameter of the second turning rod.

[0012] Further, the outer wall of the last first turning rod is in contact with the rear end face of the inner wall of the placing seat. When the electric cylinder extends, the frontmost second turning rod is in contact with the front end face of the inner wall of the placing seat.

[0013] Further, an adjustment component is installed on the two support blocks. The adjustment component is composed of a second sliding seat, a mounting seat, a second threaded rod, a third electric motor, a connecting seat, a roller, and a hydraulic cylinder. A second sliding seat is welded on the two support blocks. A mounting seat slides on the second sliding seat. A second threaded rod is rotatably installed on the second sliding seat. The second threaded rod is threadedly connected to the mounting seat. A third electric motor is fixed to the left end face of the second sliding seat. The output shaft of the third electric motor is fixed to the second threaded rod.

[0014] Furthermore, a connecting seat is slidably arranged on the mounting seat, a hydraulic cylinder is fixed on the bottom end surface of the inner wall of the mounting seat, the protruding end of the hydraulic cylinder is fixed on the connecting seat, two rollers are installed on the bottom end surface of the connecting seat, and both rollers are in contact with the ground.

[0015] Compared with the prior art, the present invention has the following beneficial effects: In terms of charge conveying, turning and leveling, the device is cleverly designed; the first motor drives the first rotating shaft to rotate, so that the toggle block continuously toggles the bottom end surface of the inner wall of the force-bearing block, realizing continuous vibration of the holding seat, which can not only effectively level the charge, but also fully turn it over, ensuring that the charge is more evenly distributed in the holding seat, providing a good foundation for subsequent heating and improving the charge processing efficiency. At the same time, the continuous toggling of the protrusion by the toggle block, combined with the elastic reset of the holding seat and the elastic collision of the first sliding block and the first sliding seat, further enhances the vibration effect, realizes vibration leveling and conveying, and optimizes the conveying and distribution process of the charge.

[0016] The heating assembly greatly improves the quality of furnace charge heating; the second motor drives the first threaded rod to rotate, which in turn drives the combustion tube to move back and forth to achieve reciprocating heating of the furnace charge. This design significantly improves the comprehensiveness of furnace charge heating, avoids uneven local heating, greatly improves heating efficiency, enables furnace charge to be heated evenly, and ensures the stability of product quality.

[0017] The auxiliary components play an important role in turning the charge and cleaning the residue; when the first turning rod and the second turning rod move left and right on the second sliding block, the charge can be turned effectively, which promotes better heating of the charge and further improves the heating effect. After the heating is completed, the electric cylinder extends to make the second turning rod staggered with the first turning rod, and at this time drives the second mounting block to move to the right. The two can efficiently clean the residue in the holding seat to the right, which greatly reduces the difficulty and workload of the cleaning work and improves the cleaning convenience of the equipment.

[0018] The adjustment component provides flexibility for the use of the device; the second threaded rod is driven to rotate by the third motor, so that the mounting base can be moved left and right, thereby adjusting the inclination angle of the device; the added hydraulic cylinder and roller further enrich the adjustment method. When the inclination of the device needs to be adjusted, the hydraulic cylinder can be driven to extend, or it can be achieved by rotating the third motor when the hydraulic cylinder is damaged, thereby meeting the needs for adjusting the inclination of the device in different scenarios, broadening the application range of the device, and enabling it to better adapt to various working conditions.
