Description

Technical Field

[0001] This utility model relates to the technical field of mineral classifiers, specifically a double-roll spiral mineral classifier. Background Technology

[0002] The double-roll spiral classifier is a specialized piece of equipment used in the mining industry, primarily for classifying ores. This equipment typically utilizes two rotating rollers and a spiral mechanism to classify materials, effectively separating them based on particle size and density. However, existing double-roll spiral classifiers directly discharge lighter and heavier particles separately through overflow and return sand troughs for further processing, failing to perform filtration during the discharge process. This necessitates external equipment for filtration and solid-liquid separation, impacting both performance and processing efficiency.

[0003] According to the patent website, a double-roll spiral mining classifier (publication number: CN109225600A) is described as including a first spiral blade, a second rotating roller, an overflow trough, etc., to perform classification work.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] This double-roll spiral mining classifier uses a first spiral blade, a second rotating roller, and an overflow trough to perform classification work. During operation, the classifier performs classification through the spiral blade, but the lighter and heavier particles after classification are discharged through the overflow trough and the discharge port without filtration and solid-liquid separation. External equipment is still required for filtration, which affects the performance and increases the complexity of operation. Therefore, this classifier needs to be improved. Utility Model Content

[0017] Compared with the prior art, this utility model provides a double-roll spiral mineral classifier, which has the following beneficial effects:

[0018] 1. This double-roll spiral mining classifier, through its first filtration mechanism, allows lighter particles to float under gravity during ore classification. These particles then flow into a storage tank via an overflow trough, where they undergo solid-liquid separation and filtration under the action of a filter frame. This improves the efficiency and convenience of subsequent processing of the classified particles. During filtration, an electric telescopic rod and a moving plate drive a push rod to move, cleaning particles at the bottom of the filter frame to prevent accumulation and maintain filtration efficiency. Wastewater is discharged through the first drain pipe. When lighter particles need to be processed, the first baffle seals the overflow trough, and the first cylinder moves the mounting plate, releasing the limit on the filter frame. The filter frame can then be removed for particle processing, making the operation convenient.

[0019] 2. This double-roll spiral mining classifier, through its second filtration mechanism, allows heavier particles to settle under gravity during ore classification. These heavier particles are then transported to the filter box via a return sand trough. The filter plates and filter box facilitate solid-liquid separation of the particles and wastewater, achieving filtration and improving the efficiency and convenience of subsequent processing of the classified particles. During filtration, the second cylinder and push plate reciprocate to clean the particles on the filter plates, preventing accumulation and ensuring effective filtration. Wastewater is discharged through the second drain pipe. To remove heavier particles, simply seal the return sand trough with the second baffle and release the seal on the filter box; the push plate then pushes the particles out for collection.

A second drain pipe 52 is fixedly connected to the bottom of the filter box 51, and a mounting frame 53 is fixedly connected to the bottom of the filter box 51. A filter plate 55 is fixedly connected inside the filter box 51.

[0040] In actual operation, when this device is used, power is first supplied to the double-roll spiral classifier body 2 via an external power supply device, enabling the double-roll spiral classifier body 2 to operate. The ore particle mixed water enters the double-roll spiral classifier body 2 through the feed inlet 3, where classification occurs under the action of the double-roll spiral classifier body 2. The first baffle 492 and the second baffle 591 are then removed from the overflow trough 491 and return sand trough 59, respectively. Under the influence of gravity, lighter particles will float to the surface and enter the storage tank 42 under the action of the overflow trough 491. Solid-liquid separation and filtration then occur under the action of the filter frame 44.

Under the action of the push rod 48, the particles accumulated at the bottom of the filter frame 44 can be cleaned to avoid accumulation affecting the filtration effect. The separated wastewater will be discharged through the first drain pipe 43. When it is necessary to process the particles in the filter frame 44, simply slide the first baffle 492 into the overflow groove 491 to seal it, and make the first cylinder 493 drive the mounting plate 494 and the insertion rod 495 to move, so that the insertion rod 495 releases the limit on the filter frame 44, and the filter frame 44 can be taken out to process the lighter particles.

[0041] Under the influence of gravity, heavier particles will settle, and under the action of the double-roll spiral classifier body 2, the heavier particles will be transported to the filter box 51 through the return sand trough 59. Under the action of the filter plate 55 and the filter box 51, the particles and sewage can be separated into solid and liquid, achieving the filtration effect. During the filtration process, the push plate 58 is driven by the second cylinder 57 to move back and forth, which can clean the particles on the filter plate 55 under the action of the push plate 58, so as to avoid the accumulation affecting the filtration effect of the filter plate 55. The separated sewage will be discharged through the second drain pipe 52. When it is necessary to process the particles on the filter plate 55, simply slide the second baffle 591 into the return sand trough 59 to seal it, and drive the sealing plate 593 to move, so that the sealing plate 593 releases the seal on the filter box 51. Under the action of the second cylinder 57 and the push plate 58, the particles can be pushed out for processing of the heavier particles.
