Description

Technical Field

[0001] The utility model belongs to the technical field of medium frequency furnace lining processing, in particular to a static weighing device for medium frequency furnace lining. Background Art

[0002] In the metallurgical industry, medium-frequency furnaces are crucial heating equipment. The quality and weight of their linings directly impact the furnace's service life, heating efficiency, and final product quality. Furnace linings are typically made from a mixture of multiple raw materials, and precise control of the mixing ratio is crucial to ensuring lining performance. However, traditional lining mixing and weighing processes often suffer from insufficient precision, low efficiency, and equipment fragility.

[0003] Specifically, after mixing, traditional furnace lining materials are typically weighed using simple mechanical scales or manual methods. This method not only has limited accuracy but also makes real-time monitoring and adjustment difficult. This makes it difficult to precisely control the mixing ratio of the furnace lining, which in turn affects the performance of the furnace lining. Furthermore, since the furnace lining is placed directly on the weighing platform during the weighing process, prolonged heavy pressure and possible accidental collisions can easily damage the weighing equipment, shortening its service life.

[0004] In order to overcome the above technical defects, improve the mixing accuracy and weighing efficiency of furnace linings, and protect the weighing equipment from damage, there is an urgent need for a device that can achieve accurate static weighing of the furnace lining in the mixing tank and effectively protect the weighing equipment in the non-weighing state. Summary of the Invention

[0005] The purpose of this utility model is to address the problems existing in the prior art and provide a static weighing device for the lining of a medium frequency furnace. Through innovative mechanical structure design, it can achieve accurate static weighing of the furnace lining and effectively protect the electronic scale when not weighing, thereby improving production efficiency and product quality and extending the service life of the equipment.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a static weighing device for the lining of a medium frequency furnace, comprising a load-bearing frame arranged around a mixing tank and a vertical frame located on the periphery of the load-bearing frame, a weighing frame carrying the load-bearing frame is provided on the inner side of the vertical frame and on both sides of the load-bearing frame, the upper surface of the weighing frame is provided with a limiting frame movably connected to the load-bearing frame, a hydraulic cylinder is provided on the upper surface of the two weighing frames and on the side of the limiting frame, the movable end of the hydraulic cylinder is provided with a load-bearing plate movably connected to the limiting frame and the weighing frame, and an electronic scale is provided on the upper surface of the weighing frame and on the inner side of the load-bearing frame.

[0007] By arranging the supporting frame around the mixing tank and the peripheral vertical frame structure, in conjunction with the weighing frame mounted on the inner side of the vertical frame and the electronic scale arranged on the inner side of the limiting frame, accurate static weighing of the furnace lining in the mixing tank is achieved. This design can ensure that the weight of the furnace lining is monitored and adjusted in real time when the furnace lining is mixed, thereby improving production efficiency and product quality. When weighing is not required, the supporting frame can be lifted using the supporting plate so that it cannot contact the electronic scale, thereby effectively protecting the electronic scale and improving its service life.

[0008] Furthermore, the stand is a square frame with a docking plate on top, a nozzle for the feed pipe, and a flexible docking sleeve at the bottom for docking with the mixing tank. The square frame design with the docking plate and nozzle at the top facilitates docking with the feed pipe, while the flexible docking sleeve at the bottom allows for tight docking with the mixing tank, reducing leakage and waste of materials during transport.

[0009] Furthermore, the soft docking tube is a pleated telescopic cloth tube, and the length of the soft docking tube after stretching is greater than the distance between the docking plate and the weighing frame. Such a design can avoid the top of the stand generating pulling force on the mixing tank, and can allow all the weight of the mixing tank to be borne by the weighing frame, thereby effectively ensuring the accuracy of the electronic scale.

[0010] Furthermore, the support frame includes a support frame plate arranged around the mixing tank. Two support beams are symmetrically positioned on either side of the support frame plate, extending through the limiting frame. A lifting opening, extending transversely through the support beams, is defined at the bottom of the support beam plate, located inside the limiting frame. This design enables the support frame to stably support the mixing tank, and the lifting opening cooperates with the hydraulic cylinder and support plate to achieve the raising, lowering, and positioning of the mixing tank.

[0011] Furthermore, two sides of the limiting frame are provided with through openings aligned with the bearing plate and the lifting opening, and the inner bottom wall of the through opening is spaced 0.5-1 cm from the upper surface of the electronic weighing device.

[0012] Through openings are opened on both sides of the limit frame and a certain distance is maintained from the upper surface of the weighing frame. This design helps to avoid interference or collision problems caused by too small a distance when the load-bearing plate passes through the limit frame. In addition, this design can prevent the load-bearing plate from contacting the electronic scale after lifting the load-bearing beam plate, thereby effectively protecting the electronic scale.

[0013] Furthermore, the length of the supporting plate is greater than the width of the limiting frame, an upper edge of the supporting plate facing the limiting frame is provided with an oblique cut, and the lifting port is provided with an incident cut matching the oblique cut on the side facing the oblique cut.

[0014] The design of the supporting plate having a length greater than the width of the limiting frame allows the limiting frame to be passed through by the supporting plate, so that the supporting plate can lift the supporting beam plate more stably. The design of the oblique cut and the incident cut enables the supporting plate to lift the supporting beam plate smoothly.

[0015] Furthermore, the two weighing frames are each equipped with two limiting frames, and the hydraulic cylinder is a bidirectional hydraulic cylinder located in the middle between the two limiting frames. The hydraulic cylinder can act on the two limiting frames and the load-bearing plate simultaneously, thereby achieving a more uniform and stable lifting effect.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. By integrating the electronic scale directly into the weighing frame and closely cooperating with the mixing tank's support frame, accurate static weighing of the furnace lining is achieved. This ability to monitor and adjust the weight of the furnace lining in real time significantly improves production efficiency and product quality, and reduces production problems caused by inaccurate weight.

[0018] 2. A non-contact mechanism is designed between the load plate and the electronic scale. When weighing is not required, the load plate can lift the load frame to separate it from the electronic scale, effectively preventing the electronic scale from being damaged by prolonged pressure or accidental collision, thereby extending its service life.

[0019] 3. The vertical frame adopts a square frame design, with a docking plate and pipe opening on the top and a soft docking tube at the bottom, which is convenient for docking with the feed pipe and mixing tank, reduces material leakage, and improves the overall practicality of the equipment and material transmission efficiency;

[0020] 4. The soft docking design of the pleated telescopic cloth tube ensures that all the weight of the mixing tank is borne by the weighing frame and is not affected by the tension at the top of the stand, further ensuring the accuracy of weighing;

[0021] 5. The design of the load-bearing frame is stable. The load-bearing frame and load-bearing beam are tightly integrated with the mixing tank, ensuring the stability of the mixing tank during the weighing process. At the same time, the bidirectional action and symmetrical layout of the hydraulic cylinder achieve a more uniform and stable lifting effect, enhancing the safety of the equipment.

[0022] 6. Detailed designs such as the through-cut, oblique cut and incident cut not only avoid interference and collision between the load-bearing plate and the limiting frame, but also enable the load-bearing plate to smoothly lift the load-bearing beam plate, thus improving the operation convenience and efficiency of the equipment;

[0023] 7. The entire device adopts a modular design concept. Components such as the weighing frame, limit frame, and load plate can be replaced or upgraded independently, which greatly reduces the maintenance cost and time of the equipment and improves the flexibility and scalability of the equipment.

[0032] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] In the description of the present invention, it should be noted that the terms "middle", "upper", "lower", "left", "right", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0034] like Figure 1 —7, the specific scheme of the embodiment is as follows: a static weighing device for the lining of a medium frequency furnace, comprising a carrier frame 6 arranged around a mixing tank 7 and a vertical frame 1 located on the periphery of the carrier frame 6, a weighing frame 2 carrying the carrier frame 6 is provided on the inner side of the vertical frame 1 and on both sides of the carrier frame 6, a limiting frame 5 movably connected to the carrier frame 6 is provided on the upper surface of the weighing frame 2, a hydraulic cylinder 3 is provided on the upper surface of the two weighing frames 2 and on the side of the limiting frame 5, a supporting plate 4 movably connected to the limiting frame 5 and the weighing frame 2 is provided on the movable end of the hydraulic cylinder 3, and an electronic scale 8 is provided on the upper surface of the weighing frame 2 and on the inner side of the carrier frame 6.

[0035] By means of the supporting frame 6 and the outer stand 1 structure arranged around the mixing tank 7, in conjunction with the weighing frame 2 mounted on the inner side of the stand 1 and the electronic scale 8 arranged on the inner side of the limiting frame 5, accurate static weighing of the furnace lining in the mixing tank 7 is achieved. This design can ensure that the weight of the furnace lining is monitored and adjusted in real time when the furnace lining is mixed, thereby improving production efficiency and product quality. When weighing is not required, the supporting frame 6 can be lifted by using the supporting plate 4 so that it cannot contact the electronic scale 8, thereby effectively protecting the electronic scale 8 and improving the service life of the electronic scale 8.

[0036] The stand 1 is a square stand with a docking plate on the top. The docking plate is provided with a nozzle adapted to the feed pipe, and a soft docking tube 9 is provided at the bottom of the docking plate to dock with the mixing tank 7. The stand 1 is designed as a square stand with a docking plate and nozzle on the top to facilitate docking with the feed pipe. At the same time, the soft docking tube 9 at the bottom can dock tightly with the mixing tank 7, reducing leakage and waste of materials during transportation.

[0037] The soft docking tube 9 is a pleated telescopic cloth tube. The length of the soft docking tube 9 after stretching is greater than the distance between the docking plate and the weighing frame 2. This design can avoid the top of the stand 1 from generating pulling force on the mixing tank 7, and can allow all the weight of the mixing tank 7 to be borne by the weighing frame 2, thereby effectively ensuring the accuracy of the electronic scale 8.

[0038] The support frame 6 comprises a support frame 61 arranged around the mixing tank 7. Two support beams 62 are symmetrically positioned on either side of the support frame 61, extending through the limiting frame 5. A lifting opening 63, extending transversely through the support beams 62, is defined at the bottom of the support beams 62, located inside the limiting frame 5. This design enables the support frame 6 to stably support the mixing tank 7 and, through the lifting opening 63, cooperate with the hydraulic cylinder 3 and support plate 4 to achieve the raising, lowering, and positioning of the mixing tank 7.

[0039] like Figure 2-4 As shown, two sides of the limiting frame 5 are provided with through openings 51 aligned with the carrying plate 4 and the lifting opening 63 , and the inner bottom wall of the through opening 51 is spaced 0.5-1 cm from the upper surface of the electronic weighing device 8 .

[0040] It should be noted that the width of the lifting port 63 and the through port 51 along the length direction of the load-bearing beam plate 62 is smaller than the width of the electronic weighing device 8 along the length direction of the load-bearing beam plate 62. In this way, it can be ensured that after the load-bearing plate 4 is separated from the limiting frame 5, the gravity of the load-bearing beam plate 62 can act on the electronic weighing device 8.

[0041] In this embodiment, through openings 51 are opened on both sides of the limiting frame 5 and maintain a certain distance from the upper surface of the weighing frame 2. This design helps to avoid interference or collision problems caused by too small a distance when the supporting plate 4 passes through the limiting frame 5. In addition, this design can prevent the supporting plate 4 from contacting the electronic scale 8 after lifting the supporting beam plate 62, thereby effectively protecting the electronic scale 8.

[0042] In addition, the thickness of the supporting plate 4 is greater than the height of the lifting opening 63 , so that the supporting beam plate 63 can be lifted by the supporting plate 4 after passing through the lifting opening 63 , thereby separating the supporting beam plate 63 from the electronic weighing device 8 .

[0043] The length of the supporting plate 4 is greater than the width of the limiting frame 5. An oblique cut is provided on the upper edge of one end of the supporting plate 4 facing the limiting frame 5. An incident cut matching the oblique cut is provided on the side of the lifting opening 63 facing the oblique cut.

[0044] like Figure 4 As shown, the design of the length of the supporting plate 4 being greater than the width of the limiting frame 5 allows the limiting frame 5 to be passed through by the supporting plate 4, so that the supporting plate 4 can lift the supporting beam plate 62 more stably. The design of the oblique cut and the incident cut enables the supporting plate 4 to smoothly lift the supporting beam plate 62.

[0045] Both weighing frames 2 are equipped with two limit frames 5, and the hydraulic cylinder 3 is a bidirectional hydraulic cylinder 3, which is located in the middle between the two limit frames 5. The hydraulic cylinder 3 can act on the two limit frames 5 and the load-bearing plate 4 at the same time, thereby achieving a more uniform and stable lifting effect.

[0046] The working principle of the above embodiment is:

[0047] First, the support frame 6 is placed around the mixing tank 7, ensuring that the support frame 61 firmly supports the mixing tank 7. The support beams 62 on both sides of the support frame 61 pass through the limiting frame 5, providing a foundation for subsequent lifting operations. The vertical frame 1 is designed as a square frame as a supporting structure. The top of the vertical frame is equipped with a docking plate. The pipe opening on the docking plate docks with the feed pipe, and the bottom is tightly docked with the mixing tank 7 through a flexible docking tube 9 to prevent material leakage. The weighing frame 2 is mounted inside the vertical frame 1, located on both sides of the support frame 6, and is used to support and carry the entire weighing system.

[0048] When weighing is required, hydraulic cylinder 3 is retracted, pulling load plate 4 gradually out of the restraining frame 5. Load beam 62 then gradually contacts electronic scale 8 until it fully presses against it. At this point, electronic scale 8 is in standby mode, ready to receive data. The furnace lining material in mixing tank 7 enters the mixing tank 7 through the feed pipe, and electronic scale 8 now acquires the material's weight. During this process, the total weight of mixing tank 7 is transmitted to electronic scale 8 via load frame 6 and load beam 62, where it is accurately measured and displayed.

[0049] Due to the design of the soft docking tube 9, the mixing tank 7 will not be subjected to the pulling force of the top end of the stand 1 during the weighing process, thereby ensuring the accuracy of the weighing.

[0050] When weighing is no longer required, hydraulic cylinder 3 reverses its rotation, pushing the supporting plate 4 through the through-holes 51 on either side of the limiting frame 5 and into the lifting opening 63 at the bottom of the supporting beam 62. The beveled cutouts on supporting plate 4 align with the entrance cutouts of lifting opening 63, ensuring that supporting plate 4 can smoothly and steadily lift supporting beam 62. As supporting plate 4 rises, mixing tank 7 and the furnace lining within it are gradually lifted, separating them from electronic weighing device 8.

[0051] This design effectively prevents the electronic weighing device 8 from being subjected to pressure or accidental collision for a long time in a non-weighing state, thereby extending its service life.

[0052] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
