Description

Technical Field

[0001] This utility model relates to the technical field of mineral sorting devices, and in particular to a spiral classifier discharge mechanism for mineral processing machines. Background Technology

[0002] In the mineral processing industry, spiral classifiers are key equipment for mineral classification. Their main function is to separate crushed minerals according to particle size, providing qualified raw materials for subsequent mineral processing operations.

[0003] Traditional spiral classifiers typically rely on the rotation of spiral blades and gravity settling to achieve classification, and then a filter screen is installed at the discharge end to separate the particle sizes.

[0004] When separating through a filter screen, the ore tends to accumulate in the discharge area, and fine materials have difficulty passing through the screen quickly, resulting in incomplete screening and certain shortcomings.

[0005] Therefore, a discharge mechanism for a spiral classifier used in mineral processing is provided to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a discharge mechanism for a spiral classifier for mineral processing machines.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A spiral classifier discharge mechanism for a mineral processing machine includes a classifying shell, which is inclined and has a fine material discharge port at the lower end and a coarse material discharge port at the upper end. It also includes:

[0009] Rotary shaft one is rotatably connected inside the graded housing;

[0010] Motor 1 is fixedly connected to the graded housing, and the output end of motor 1 is fixedly connected to rotating shaft 1.

[0011] Screw 1 is fixedly connected to the rotating shaft 1. There is a gap between the lower end of screw 1 and the lower end of the grading shell, and the fine material discharge port is located at the gap.

[0012] A screen is slidably connected to the rotating shaft. The screen is used to screen the ore at the lower end of the screw conveyor. Fine ore is discharged through the screen and through the fine material outlet, while coarse ore gradually moves upward under the action of the screw conveyor and is finally discharged through the coarse material outlet.

[0013] Multiple sets of annular arc-shaped protrusions are fixedly connected in an annular shape at equal intervals to the inner wall of the lower end of the graded shell;

[0014] Multiple sets of top rods are fixedly connected to the screen at equal intervals;

[0015] The ore is sorted by rotating shaft one. At the same time, the top rod rotates and moves gradually along the arc surface of the annular arc protrusion, gradually moving away from the bottom of the classification shell. After reaching the highest point of the annular arc protrusion, the ore is squeezed and moved. Then, under the action of the weight of the ore on the screen, the top rod will move quickly to the bottom of the classification shell, thereby generating vibration and making the ore sorted quickly.

[0016] Preferably, the screen has a square groove, and a square protrusion matching the square groove is fixedly connected to the rotating shaft.

[0017] Preferably, the grading shell is provided with a collection hopper below the fine material discharge port and a collection box below the coarse material discharge port.

[0018] Preferably, a reinforcing plate is fixedly connected to the screen, and the top rod is fixedly connected to the reinforcing plate.

[0019] Preferably, an auger shell is fixedly connected inside the collecting hopper, a second rotating shaft is rotatably connected inside the auger shell, an auger is fixedly connected to the second rotating shaft, and the top of the auger shell has a discharge port. By rotating the auger, the ore in the collecting hopper can be discharged through the discharge port.

[0020] Preferably, a second motor is fixedly connected to the auger housing, and the output end of the second motor is fixedly connected to the second rotating shaft.

[0021] Compared with the prior art, this utility model provides a discharge mechanism for a spiral classifier in a mineral processing machine, which has the following advantages:

[0022] This invention utilizes the combination of a top rod and an annular arc-shaped protrusion to cause the screen to periodically rise, fall, and vibrate during rotation. Combined with the compression of the ore, this significantly improves the grading efficiency and accuracy. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Example: Refer to Figure 1-6A spiral classifier discharge mechanism for a mineral processing machine includes a classifying shell 1, which is inclined and has a fine material discharge outlet 101 at its lower end and a coarse material discharge outlet 102 at its upper end. It also includes: a rotating shaft 202 rotatably connected inside the classifying shell 1; a motor 201 fixedly connected to the classifying shell 1, with its output end fixedly connected to the rotating shaft 202; an auger 203 fixedly connected to the rotating shaft 202, with a gap between the lower end of the auger 203 and the lower end of the classifying shell 1, the fine material discharge outlet 101 located at the gap; and a screen 3 slidably connected to the rotating shaft 202, used to screen the ore at the lower end of the auger 203, with fine ore discharged through the screen 3. The material is discharged from outlet 101, while the coarse ore is gradually moved upward by the auger 203 and finally discharged through the coarse material outlet 102. Multiple sets of annular arc-shaped protrusions 4 are fixedly connected in annular shape at equal intervals to the inner wall of the lower end of the classifying shell 1. Multiple sets of top rods 302 are fixedly connected at equal intervals to the screen 3. The ore is sorted by the rotation of the rotating shaft 202. At the same time, the top rods 302 rotate, which causes the top rods 302 to move gradually along the arc surface of the annular arc-shaped protrusions 4 and gradually move away from the bottom of the classifying shell 1. After reaching the highest point of the annular arc-shaped protrusions 4, the ore is squeezed and moved. Then, under the action of the weight of the ore on the screen 3, the top rods 302 will move quickly to the bottom of the classifying shell 1, which will generate vibration and make the ore sorted quickly.

[0032] The screen 3 has a square groove, and a square protrusion that matches the square groove is fixedly connected to the rotating shaft 202.

[0033] The grading shell 1 is provided with a collection hopper 5 below the fine material discharge port 101, and a collection box 6 is provided below the coarse material discharge port 102.

[0034] A reinforcing plate 301 is fixedly connected to the screen 3, and a top rod 302 is fixedly connected to the reinforcing plate 301.

[0035] A screw conveyor shell 501 is fixedly connected inside the collecting hopper 5. A rotating shaft 502 is rotatably connected inside the screw conveyor shell 501. A screw conveyor 503 is fixedly connected to the rotating shaft 502. The top of the screw conveyor shell 501 has a discharge port. By rotating the screw conveyor 503, the ore in the collecting hopper 5 can be discharged through the discharge port.

[0036] A second motor 504 is fixedly connected to the auger housing 501, and the output end of the second motor 504 is fixedly connected to the second rotating shaft 502.

[0037] When motor 201 is started, the output end of motor 201 drives the rotating shaft 202 to start rotating. Since the auger 203 is fixed on the rotating shaft 201, the auger 203 also rotates, feeding the ore to be classified from the high end of the classification shell 1. Under the rotation of the auger 203, the ore is continuously transported to the low end of the classification shell 1.

[0038] As the ore is conveyed to the lower end of the classifying shell 1, it falls onto the screen 3. At this time, the rotation of the rotating shaft 202 causes the screen 3 to rotate as well. The push rod 302 on the screen 3 also rotates accordingly. During this rotation, the push rod 302 gradually moves along the arc surface of the annular arc-shaped protrusion 4 on the inner wall of the lower end of the classifying shell 1, gradually moving away from the bottom of the classifying shell 1. During this upward movement, the screen 3 also moves upward, and the ore on the screen is compressed. Under this compression, smaller pieces of ore that might not have passed through the screen in time due to accumulation or other reasons will more easily leak through the screen 3. The leaked fine ore will pass through the screen 3. The fine ore is discharged from the fine material outlet 101, while the coarse ore remains on the screen 3. Under the continuous rotation and conveying action of the auger 203, the coarse ore gradually moves upward along the inclined direction of the classifying shell 1 and is finally discharged from the coarse material outlet 102, entering the collection box 6 below for collection. When the top rod 302 reaches the highest point of the annular arc protrusion 4, the ore is squeezed. Then, under the action of the weight of the ore on the screen 3, the top rod 302 moves quickly to the bottom of the classifying shell 1, thereby generating vibration. This vibration further promotes the dispersion of the ore on the screen 3, allowing the fine ore to pass through the screen more smoothly, improving the efficiency and effect of screening.

[0039] The fine ore discharged from the fine material discharge port 101 will fall into the collection hopper 5. Then the motor 2 504 will be started. The output end of the motor 2 504 will drive the rotating shaft 2 502 to rotate. Since the auger 2 503 is fixed on the rotating shaft 2 502, the auger 2 503 will also rotate.

[0040] Under the rotation of auger 2 503, the fine ore in the collection hopper 5 will be gradually transported to the discharge port at the top of auger shell 501 and discharged from the discharge port for subsequent processing or collection.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
