A batching scale for sintered ore

Abstract

This utility model belongs to the field of batching scale technology, specifically a batching scale for sintered ore, including a feeding mechanism, a weighing mechanism, and a material handling mechanism. The weighing mechanism includes: a barrel body with a support plate fixedly connected to its inner wall; a sleeve with a pressure sensor installed inside and a rod inserted inside; and a weighing pan fixedly installed at the top of the rod, funnel-shaped with a round opening at its center. The material handling mechanism includes a material bin. The material handling mechanism uses a servo motor to drive a spiral plate to handle material. The material is returned to the material bin through return troughs one and two. When the material at the bottom of the spiral plate reaches the bottom and cannot be drawn, the servo motor drives a lead screw to rotate, which moves the slider to adjust the position of the spiral plate. Since the bottom of the spiral plate is close to the weighing pan, it can be moved to a different position to continue drawing material, avoiding situations where no material can be drawn.

Description

Technical Field

[0001] This utility model belongs to the technical field of batching scales, specifically relating to a batching scale for sintered ore. Background Technology

[0002] In the iron and steel metallurgical industry, the production of sinter is a crucial step in the ironmaking process. The quality of the sinter batch directly affects the quality of the final product and production efficiency.

[0003] Patent application (publication number: CN216695236U) discloses a weighing control device for adjustable sintering batching. This addresses the problem that existing ordinary weighing devices typically control sintering batching at the supply end, failing to effectively return the batching amount to the predetermined value when it exceeds it. The device includes a suction pipe installed inside the batching cylinder, fixedly connected to the cylinder with fastening screws. A suction pump is installed on one side of the batching cylinder, fixedly connected to the cylinder with a mounting base. The suction pipe is fixedly connected to the suction pump with a flange. A return pipe is installed above the suction pump, fixedly connected to the suction pump with a flange.

[0004] In the aforementioned application, excess sintering material can be extracted using a suction pump and suction pipe. However, since the position of the suction pipe is fixed, it can only extract the sintering material at the corresponding position. When the amount of sintering material is relatively small, it may be impossible to extract it. Utility Model Content

[0032] This sintering ore batching scale uses a weighing mechanism that combines a pressure sensor with a rod and a weighing pan. This allows the material weight to directly act on the pressure sensor, improving weighing accuracy. The funnel-shaped weighing pan and central opening facilitate material collection and descent, reducing residue. The material handling mechanism uses a servo motor to drive a spiral plate to handle the material. The handled material flows back to the material bin through return troughs one and two. When the material at the bottom of the spiral plate is exhausted and no more material can be drawn, or when the preset batching amount is too low, the servo motor drives a lead screw to rotate, which moves the slider and adjusts the position of the spiral plate. Since the bottom of the spiral plate is close to the weighing pan, it can be moved to a different position to continue drawing material, avoiding situations where no material can be drawn.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0048] Please see Figure 1-5 This utility model provides the following technical solution: a batching scale for sintered ore, comprising:

[0049] Feeding mechanism 1;

[0050] Weighing mechanism 2;

[0051] Material handling mechanism 3;

[0052] Weighing mechanism 2 includes:

[0053] The barrel body 201 has a support plate 202 fixedly connected to its inner wall;

[0054] Sleeve 203, a pressure sensor 209 is installed inside sleeve 203, and a rod 204 is inserted inside sleeve 203;

[0055] The weighing pan 205 is fixedly installed at the top of the plug rod 204, and is funnel-shaped with a round opening in the center;

[0056] Material handling mechanism 3 includes:

[0057] Material bin 2 301, the bottom of material bin 2 301 is fixedly connected to cylinder 2 302;

[0058] Servo motor 2 303, the output end of servo motor 2 303 is fixedly connected to rotating rod 2 304, and the surface of rotating rod 2 304 is fixedly connected to spiral plate 2 305;

[0059] Slider 306 is fixedly connected to the surface of cylinder 302;

[0060] Slide rail 307 is fixedly installed on the top of barrel body 201;

[0061] A fixed plate 308 is provided, on the upper surface of which a servo motor 309 is fixedly mounted. A reducer 311 is fixedly connected to the output end of the servo motor 309. A lead screw 310 is fixedly connected to the output end of the reducer 311, and the lead screw 310 is threadedly connected to the slider 306.

[0062] In this embodiment, the weighing mechanism 2 adopts a structure in which the pressure sensor 209 cooperates with the insertion rod 204 and the weighing pan 205, so that the weight of the material directly acts on the pressure sensor 209, improving the weighing accuracy. The funnel-shaped weighing pan 205 and the central circular opening design facilitate the collection and falling of materials, reducing residue. The material picking mechanism 3 drives the spiral plate 305 to pick up materials through the servo motor 303. The picked-up materials can flow back to the material box 101 through the return trough 4 and the return trough 5. When the material at the bottom of the spiral plate 305 is exhausted and no more material can be picked up, or when the preset feeding amount is too small, the servo motor 309 drives the lead screw 310 to rotate, which can drive the slider 306 to move, realizing the position adjustment of the spiral plate 305. Since the bottom of the spiral plate 305 is relatively close to the weighing pan 205, it can change the position to continue picking up materials, avoiding the situation where no material can be picked up.

[0063] Furthermore, the feeding mechanism 1 includes:

[0064] Material bin 101, a servo motor 102 is fixedly installed on one side of the material bin 101, a rotating rod 103 is fixedly connected to the output end of the servo motor 102, and a spiral plate 104 is fixedly connected to the surface of the rotating rod 103.

[0065] Cylindrical 105 is fixedly installed on one side of material box 101, and the other end passes through barrel body 201. Spiral plate 104 is located inside cylindrical 105.

[0066] Specifically, the material bin 101 is used to store sintered mineral materials to be batched. The cylinder 105 is welded to one side of the material bin 101, and the other end extends through the barrel 201 to the top of the weighing pan 205. The servo motor 102 drives the rotating rod 103 and the spiral plate 104 to rotate, so that the material in the material bin 101 is transported to the weighing mechanism 2 through the cylinder 105.

[0067] Furthermore, the surface of the material bin 2 301 is movably connected to the return trough 1 4, and one side of the material bin 2 301 is provided with a discharge port corresponding to the return trough 1 4. One side of the material bin 1 101 is fixedly connected to the return trough 2 5, and is provided with a feed port.

[0068] Specifically, by setting up return trough 1 4 and return trough 2 5, excess or residual materials during the material handling process can be recycled to material bin 101, realizing the recycling of materials, reducing waste, and lowering production costs.

[0069] Furthermore, the weighing mechanism 2 also includes:

[0070] Weighing mechanism 2 also includes:

[0071] The support rail 206 is fixedly installed on the bottom of the weighing pan 205. A baffle 207 is slidably installed inside the support rail 206, and a threaded hole is opened inside the baffle 207.

[0072] Servo motor 4 208 is fixedly installed on the side of support rail 206 and fixedly connected to weighing pan 205. The output end of servo motor 4 208 is fixedly connected to lead screw 210, which is threadedly connected to baffle 207 through threaded hole.

[0073] Specifically, the baffle 207 is located directly below the central opening of the weighing pan 205. When the servo motor 208 is started, it can drive the lead screw 210 to rotate. In turn, the lead screw 210 can drive the baffle 207 to move along the support rail 206, thereby opening and closing the central opening of the weighing pan 205.

[0074] Furthermore, a control box 6 is fixedly installed on the lower surface of the fixing plate 308. The control box 6 includes a signal receiver, a processor, a controller, a display screen, and operation buttons.

[0075] Specifically, the signal receiver receives the signal from the pressure sensor 204, which is then processed by the processor and displayed on the screen. The controller controls the operation of servo motor 102, servo motor 303, servo motor 309 and electric telescopic rod 207 according to the set parameters.

[0076] Furthermore, both slider 306 and slide rail 307 are symmetrically arranged.

[0077] Specifically, this facilitates the stability of movement of components such as cylinder 2 302 and material box 2 301.

[0078] Furthermore, support legs 7 are fixedly connected to the surfaces of both material bin 2 301 and material bin 1 101.

[0079] Specifically, the support leg 7 is made of high-strength steel to ensure the stable placement of material box 101 and material box 2 301.

[0080] The working principle or usage process of this utility model is as follows: When using this utility model, the material weight parameters are set via the operation buttons on the control box 6. After starting the equipment, the control box 6 controls the servo motor 102 to start, driving the rotating rod 103 and the spiral plate 104 to rotate, thus conveying the material in the material bin 101 through the cylinder 105 to the weighing pan 205 of the weighing mechanism 2. At this time, the baffle 207 is in the closed state, blocking the central opening of the weighing pan 205. The material accumulates on the weighing pan 205, and the weight of the material is transmitted to the pressure sensor 204 through the insertion rod 204. The pressure sensor 204 converts the pressure signal into an electrical signal and transmits it to the control box 6. After processing by the processor, the real-time weight is displayed on the screen. When the material weight reaches the set value, the control box 6 controls the servo motor 102 to stop running. When the material weight exceeds the set value, the control box 6 controls the servo motor 303 to start driving the rotating rod 304 and the spiral plate 305 to rotate, conveying the excess material on the weighing pan 205 into the material bin 301. The material passes through the material bin 301... The material enters the return trough 4 through the outlet and then flows back to the material box 101 through the return trough 25 to achieve recycling. When the material at the bottom of the spiral plate 205 is exhausted and cannot be extracted, the control servo motor 309 starts and drives the lead screw 310 to rotate through the reducer 311, thereby driving the slider 306 to move along the slide rail 307, so that the cylinder 202 and the spiral plate 205 of the material picking mechanism 3 are translated, so that the material is picked up from a different position. When the weight reaches the set value, the material picking stops. The control box 6 controls the servo motor 408 to start and drive the lead screw 210 to rotate. Then the lead screw 210 can drive the baffle 207 to move along the support rail 206, so that the central opening of the weighing pan 205 opens and the material falls from the opening.

[0081] Finally, it should be noted that the above descriptions are merely preferred embodiments of this utility model and are not intended to limit the utility model. The selection and detailed description of these embodiments in this specification are for the purpose of better explaining the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
