Description

Technical Field

[0001] The utility model belongs to the technical field of sintering production equipment, and particularly relates to an inclined loosener for a sintering machine. Background Art

[0002] The sintering machine loosener is a device that improves the air permeability of sintering. As the sintering machine trolley moves forward with the mixed material, the loosening rods naturally form holes at the bottom of the material layer. Under the action of the sintering material's gravity, the sintering material around the holes collapses, forming a loose area at the bottom of the mixed material layer, thereby significantly improving the air permeability of the entire material layer.

[0003] After the existing loosener is installed on the sintering machine, the loosener is kept fixed, and the loosening rod of the loosener is parallel to the plane of the sintering machine, and a certain gap is formed. However, the existing gap is fixed. For different types of sintered materials, the loosening effects of the loosening rods with fixed gaps are different. The application range of the loosener is narrow and the limitations are large. It is necessary to replace the feeding rods with different gaps in a targeted manner to ensure the loosening effect; the existing loosening rods are set horizontally, and the material is loosened at a "point" on the cross section of the material layer, which has limited improvement on the air permeability of the sintered material layer; the inclination angle of the loosening rod affects the loosening speed of the sintered material. Different types of sintered materials require feeding rods with different inclination angles to loosen. The manufacture of multiple types of feeders increases the manufacturing cost.

For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and may encompass internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on specific circumstances.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referenced. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. Furthermore, "plurality" and "several" mean two or more, unless otherwise specifically defined.

[0038] Please also refer to Figures 1 to 7, the inclined loosener of the sintering machine provided by the utility model is now described. The inclined loosener of the sintering machine includes a base 1, a plurality of mutually parallel loosening rods 2 and an adjustment component 3. The base 1 is a rectangular component, and the base 1 is installed on the sintering machine; a plurality of mutually parallel loosening rods 2 are spaced and distributed along the long axis of the base 1, and the long axis of each loosening rod 2 is perpendicular to the long axis of the base 1, and is set at an angle with the horizontal plane; one end of the loosening rod 2 is rotatably connected to the base 1, and the other end forms a swing end, and the plurality of loosening rods 2 swing synchronously around the same swing axis, and the swing axis is parallel to the long axis of the base 1; the adjustment component 3 is provided between the base 1 and the loosening rod 2 to adjust the angle between the loosening rod 2 and the horizontal plane.

[0039] It should be noted that the multiple loosening rods 2 swing synchronously, the adjustment component 3 is mechanically connected to one of the loosening rods 2, and the inclination angles of all the loosening rods 2 can be changed by changing the angle between one loosening rod 2 and the horizontal plane.

[0040] In specific implementation, the base 1 and the loosening rod 2 are both steel components to ensure the strength in use.

[0041] During specific implementation, the loosening rod 2 can be made of stainless steel, and the outer periphery of the loosening rod 2 is covered with a silicon nitride ceramic layer.

[0042] Compared with the prior art, the inclined loosener of the sintering machine provided in this embodiment has a loosening rod 2 and a base 1 that are movably connected. The angle between the loosening rod 2 and the base 1 is controlled by the adjusting component 3, so that the loosening rod 2 and the base 1 are adjusted to a predetermined angle, so that the loosening rod 2 can be inserted into the sintering material at different angles, thereby improving the air permeability of the sintering material layer and thus increasing the production volume. This device changes the angle between the loosening rod 2 and the horizontal plane by adjusting the component 3, so that the same device can be used to loosen different sintering materials, thereby expanding the scope of use of the device, improving adaptability, reducing use costs, and reducing economic investment.

[0043] In some embodiments, see Figure 7 The loosening rod 2 has an L-shaped cross-section and includes a first piece 21 and a second piece 22, which are perpendicular to each other. The surface of the first piece 21 is parallel to the vertical direction. When the surface of the first piece 21 is parallel to the vertical direction, the sintering material first contacts the first piece 21. The contact area between the first piece 21 and the sintering material is small, allowing for rapid insertion into the sintering material. The surface of the second piece 22 is perpendicular to the surface of the first piece 21. The second piece 22 can increase the gap between the sintering material and the first piece 21, thereby improving the permeability of the sintering material.

[0044] Specifically, the loose material rod 2 is angle steel, which is available in large quantities in factories. The angle steel has a wide source, high strength, and low processing cost, thus meeting the needs of the loose material rod 2 .

[0045] In some embodiments, see Figure 1and Figure 2 The adjustment component 3 includes two articulated seats 31 and a rotating shell 32 with a rectangular structure. The long axis of the rotating shell 32 is parallel to the long axis of the base 1. One side of the rotating shell 32 is connected to multiple loosening rods 2. The two articulated seats 31 are symmetrically arranged at both ends of the rotating shell 32 and are fixedly connected to the base 1 respectively. The two articulated seats 31 are respectively hinged to the rotating shell 32, and the hinge axis of the articulated seat 31 coincides with the swing axis of the loosening rod 2.

[0046] In a specific implementation, the hinge seat 31 is fixed to the base 1 by welding, and the two hinge seats 31 are coaxially arranged.

[0047] The adjustment assembly 3 provided in this embodiment has a simple structure. The two ends of the rotating shell 32 are respectively hinged to the corresponding hinge seats 31, so that the rotating shell 32 can rotate along its own axis, thereby driving the multiple loosening rods 2 to swing, thereby changing the tilt angle of the loosening rods 2. The whole process does not require complex mechanical coordination, is simple to manufacture, and reduces the difficulty of operation.

[0048] During specific implementation, a driving motor may be provided on the base 1 , and the output shaft of the motor is coaxially connected to the rotating shaft of the hinge seat 31 to drive the rotating housing 32 to rotate.

[0049] In some embodiments, see Figure 3 and Figure 4 The end surface of the rotating shell 32 is also provided with a plurality of fixing holes 321 distributed around the hinge axis; the hinge seat 31 is also provided with an adjustment hole 311, and the adjustment hole 311 corresponds to the fixing hole 321 at one of them; the adjustment component 3 also includes a fastener 33, which passes through the fixing hole 321 and the adjustment hole 311 to achieve locking of the rotation angle of the rotating shell 32.

[0050] In this embodiment, fastener 33 sequentially passes through adjustment hole 311 and fixing hole 321, maintaining a fixed connection between rotating housing 32 and hinged base 31, thereby securing rotating housing 32 to base 1. This ensures the stability of loosening rod 2 during operation and ensures the proper loosening of the material. By selectively aligning adjustment hole 311 with fixing hole 321, rotating housing 32 can be secured at various tilt angles, ensuring operational stability. Fastener 33 is easy to install, reducing adjustment costs.

[0051] Optionally, the fastener 33 is a high-strength bolt, which is widely available and has high strength, and can be plugged or screwed into the fixing hole to improve the connection stability. The fastener 33 can also be a pin, as long as it can sequentially penetrate the adjustment hole 311 and the fixing hole 321 and maintain relative fixation.

[0052] In some embodiments, the angle between the loosening rod 2 and the horizontal plane is in the range of 60-80 degrees. When the angle between the loosening rod 2 and the horizontal plane is within the range of 60-80 degrees, the loosening effect of the loosening rod 2 is optimal, ensuring the air permeability of the sintered material.

[0053] Specifically, common included angles between the loosening rod 2 and the horizontal plane are 60°, 70° and 80°.

[0054] In some embodiments, see Figure 6 Adjustment assembly 3 also includes a support frame 34 and a reinforcement rod 35. Support frame 34 is mounted on base 1. The ends of reinforcement rod 35 are hinged to support frame 34 and rotating housing 32, respectively. Reinforcement rod 35 is a telescopic rod. Support frame 34, reinforcement rod 35, and rotating housing 32 enclose a quasi-triangular space, enhancing stability. Reinforcement rod 35 reinforces rotating housing 32 from its upper side, ensuring stability during use and improving the structural strength of the device.

[0055] The two ends of the reinforcement rod 35 are respectively hinged to the support frame 34 and the rotating housing 32, and the two intersection axes are parallel to each other. After the rotating housing 32 is adjusted to a fixed position, the rotating housing 32 and the hinge seat 31 are fixed, and the length of the reinforcement rod 35 is fixed, thereby firmly connecting the rotating housing 32 and the support frame 34, further securing the rotating housing 32 and ensuring the stability of the rotating housing during use. The reinforcement rod 35 acts as a telescopic rod, changing its length as the rotating housing 32 rotates to accommodate the normal rotation of the rotating housing 32 and ensure the normal rotation of the rotating housing 32. When the rotating housing 32 rotates to the designated position, the reinforcement rod 35 stops extending and retracting, preliminarily securing the rotating housing 32.

[0056] In this embodiment, the reinforcement rod 35 is a telescopic rod that can adapt to the rotation of the rotating shell 32 to ensure that it can always be connected to the rotating shell 32.

[0057] As a connection method of the reinforcement rod 35, the reinforcement rod 35 includes two screws and screw sleeves with opposite rotation directions. The two screws are hinged to the support frame 34 and the rotating shell 32 respectively. The ends of the two screws close to each other are screwed to the screw sleeves respectively. By adjusting the screw connection distance between the screw and the screw sleeve, the overall length of the reinforcement rod 35 can be changed.

[0058] As another embodiment of the reinforcement rod 35 , the reinforcement rod 35 is a plurality of segmented rods connected end to end along a preset direction. The length of the reinforcement rod 35 can be changed by increasing or decreasing the number of segmented rods.

[0059] In some embodiments, see Figure 2 and Figure 5The loosening rod 2 is a tubular structure with a closed swing end. A temperature-regulating chamber is provided within the loosening rod. The inclined loosening device of the sintering machine also includes a temperature-regulating assembly 4. In this embodiment, the loosening rod 2 has a temperature-regulating chamber 23 within it. The temperature-regulating assembly 4 is disposed within the temperature-regulating chamber 23 to adjust the temperature of the loosening rod 2 to form a predetermined cavity within the sintering material, thereby improving the permeability of the sintering material.

[0060] In some embodiments, see Figure 5 The temperature control component 4 also includes a heating tube 41 arranged inside the loosening rod 2. The heating tube 41 is bent to form a plurality of U-shaped sections, and the plurality of U-shaped sections are respectively placed in the corresponding temperature regulating chambers 23. A heating medium flows in the heating tube 41, and the inlet and outlet of the heating tube 41 respectively extend out of the rotating shell 32 and are connected to the heat source. The heating tube 41 is responsible for transporting the heating medium, preventing the heating medium from directly contacting the loosening rod 2, and ensuring that the heating medium will not leak due to cracks on the loosening rod 2, thereby improving work safety and reducing losses. The design of the U-shaped section can increase the contact area between the heating medium and the loosening tube 2, thereby improving heating efficiency.

[0061] In specific implementation, the heating medium can be water or industrial oil.

[0062] In some embodiments, see Figure 5 A temperature sensor 42 is provided in the temperature regulating chamber 23. The temperature sensor 42 can detect the temperature in the temperature regulating chamber 23. Once the temperature is abnormal, the temperature sensor 42 transmits the data to the staff. The staff judges whether the loose material rod 2 is damaged based on the data, and then controls the flow or stillness of the heating medium to reduce losses.

[0063] During specific implementation, the temperature sensor 42 is communicatively connected to a terminal, which is a mobile terminal (such as a mobile phone and a tablet computer).

[0064] In some embodiments, see Figure 2 One side of the rotating shell 32 is opened, and a detachable end cover 322 is provided at the opening. The setting of the end cover 322 allows the staff to visually inspect the heating tube 41 in the rotating shell 32, reducing the difficulty of inspection and facilitating maintenance.

[0065] In specific implementation, the end cover 322 is fixed to the opening of the rotating shell 32 by screws. When maintenance is needed, the screws can be removed. The disassembly and assembly are convenient, the operation difficulty is low, and it is suitable for promotion.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
