[0001] FLEXIBLE FLOATING SIEVE

[0002] Technical Field of the Invention

[0003] The present invention relates to a sieving machine with a flexible body, flexible sieve structure and the ability to float in water, developed to classify or sieve micronized grains in the mining industry.

[0004] State of the art

[0005] Sieving and classification processes have an important place in the mining sector in terms of improving product quality and, on the other hand, selling it at higher prices. Mineral ore extracted from underground can only be enriched after it is brought to a certain size. While this enrichment is done with shaking tables, the grain size of the ore is required to be below 2 mm. The grain size material reaching this size is obtained through sifting, in other words, with sieves. However, enrichment by flotation is applied to grain sizes below 500 pm. For enrichment by leaching, it is necessary to go down to finer sizes and perform the sieving process at these sizes. Classification before any enrichment process is important for the efficiency of this enrichment. Classification is the first step of enrichment. In this case, the most used classification machine in ore preparation is vibrating sieves. Hydrocyclones or spiral classifiers are also used for classification at very fine sizes of less than 100 pm. The reason for this is that vibrating sieves cannot sieve efficiently below 100 pm in industrial terms. However, materials larger than 100 pm can be classified efficiently with sieves. At the same time, there is no alternative to these sieves.

[0006] Another purpose of classification is to prepare the product in the size needed by the industry. For example, the grain size of the quartz mineral to be used in the glass industry must be below 300 pm. Quartz minerals, which are larger in size, cause problems when melting in glass production and reduce the quality of the glass. In this regard, it is desired to have a standard product of a certain size and the preparation of this product is done with screen machines. Again, products such as asphalt material (- 30+22 mm), concrete material (-10+0.5 mm), balancing material (-1 10+40 mm) produced in quarries are required to be in certain sizes. Sieves are also used to obtain these different size groups. In short, sieves are machines that enable any mine product to be brought to the desired size and are widely used. Sieves are used in almost every mining operation.

[0007] The biggest problem in sieving machines is clogging of the sieve surfaces, breaking of the sieve body, or excessive electricity consumption. Flexible rubber surfaces have been developed to prevent clogging of the sieve surfaces. In addition, sieve surfaces known as “non-blinding sieves” were developed. However, since these surfaces are mounted on the rigid sieve body, they cannot prevent the sieve body from breaking. Similarly, these sieve surfaces cannot reduce the electricity consumption of rigid steel sieves weighing tons (5-10 tons on average). Here, in order to prevent sieve clogging and breakage of the sieve body, and also to reduce energy consumption, it is necessary to design a flexible and lightweight sieving machine that is not made of metal when considering a sieve.

[0008] Although various suggestions and applications have been developed for metal sieves in the state of the art, these developments are not sufficient. Some applications for inventions developed for this purpose are given below.

[0009] The patent file numbered "TR2005031 16" in the known state of the art has been examined. In the invention of the application, the application of processes such as sieving, separation, dedusting, filtration of different minerals such as mines, ceramics, coal, sand, etc. is disclosed. It is explained that the sieve for sieving the materials has at least one body to which it is fixed, a plurality of sieve legs, and that these legs and the body are not subjected to vibration, but only the sieve is subjected to multifrequency irregular vibration. This is a sieve vibration mechanism that produces multifrequency irregular vibration, containing a vibration shaft, connected to the body edges on the downward side of the sieve. Here, the vibration of the vibration shaft to the sieve is carried out by multiple sieve frames positioned throughout, at specified intervals. In this way, the sieve surface works only with non-planar, multi-frequency vibration with the movement of the sieve frame, thus avoiding impact operation. The vibrating sieve here can only work on land, as there is no additional equipment that can enable it to be used in water. The patent file numbered "CN208146411 U" in the known state of the art has been examined. In the invention of the application, a vibrating sieve system is mentioned. A sieve surface suspension vibrating sieve is disclosed which comprises a flexible sieve surface, an excitation source, and a striking bracket positioned below the sieve surface. In addition, a tapping device is placed under the sieve surface, the tapping device is placed on the tapping bracket, the sieve segment of the sieve surface is not fixedly connected with the tapping bracket, and the sieving of the sieve surface, the segment is not fixedly connected with the tapping device. It is equipped with the sieve surface pressing frame, and the sieve section is not fixedly connected to the sieve surface pressing frame. The sieve described here does not have any features to ensure the sieving process on water. In addition, since the body is not made of elastic and special materials, it has no strength or flexibility against breaking. In addition, it is insufficient to reach high frequencies.

[0010] The patent file numbered "CN107225086A" in the known state of the art has been examined. The invention of the application describes a single-layer, heavy-duty, high- frequency fine powder sieve, especially in the field of ore processing and classification technology. The drive mass body consists of a drive system and a sieve frame of the sieving machine. The drive system moves the sieve frame. The drive system consists of a drive and an exciter, and the exciter is driven directly through the drive; the sieving frame of the sieving machine is fixed by a vibration exciter beam supporting the exciter, a side plate of the sieving machine and a side plate of the sieving machine. This sieve system, which can reach high frequencies, does not have a mechanism that can continue the sieving process on water.

[0011] In the state of the art applications, there are vibrating sieve systems with different features for minerals and similar materials. Problems of jamming during sieving, bouncing and cracking / breaking of the sieve body due to the lack of elastic body wall, inability to obtain the desired efficiency due to the frequency not being high, and the lack of floating equipment to be used in mineral exploration in wetlands cause insufficient opportunities for sieves used for sieving minerals.

[0012] As a result, due to the abovementioned disadvantages and the insufficiency of the current solutions regarding the subject matter, a development is required to be made in the relevant technical field. Object of the Invention

[0013] The present invention relates to a sieving machine that has the ability to float in water, developed to classify or sieve micronized grains in the mining industry.

[0014] The most important object of the invention is to prevent breakages and extend the life of the sieve with its flexible body structure and flexible sieve surface.

[0015] Another object of the invention is that it has the advantage of having an air-filled tube under the sieve mechanism, allowing it to float in water for mineral exploration in water and to be able to sieve on water.

[0016] Another object of the invention is that it does not have a metal body and is therefore lightweight and consumes less power.

[0017] Another object of the invention is to provide vibration at maximum efficiency, as the entire machine can vibrate when vibrated, with its flexible body.

[0018] Another object of the invention is to ensure the sieving of small sized materials by providing high frequency.

[0019] Another object of the invention is to use the power source of the vibration motor as electricity through a power cable.

[0020] The structural and characteristic features of the present invention will be understood clearly by the following drawings and the detailed description written with reference to these drawings. Therefore the evaluation shall be made by taking these figures and the detailed description into consideration.

[0030] Description of the Invention

[0031] The present invention relates to a sieving machine with a flexible body, flexible sieve structure and the ability to float in water, developed to classify or sieve micronized grains in the mining industry.

[0032] The sieve machine consists of flexible sieve body (1 ), flexible sieve surface (2), vibration motor (3), inner tube (4), power cable (5).

[0033] The part in which the sieving process takes place is the flexible sieve body (1 ), which contains reinforcement materials such as steel wire, steel mesh, polyester, rayon, nylon in its structure in order to be both flexible and robust. The entire body and its parts consist of rubber, plastic and other polymer type hydrocarbon components. Here, the flexible sieve body (1 ) prevents the sieve from breaking with its flexibility. In addition, it is made of solid and durable materials and has the advantage of having a very low amount of metal in its structure, making it a lightweight device. With its lightness, it can prevent high energy consumption. The vibration motor (3) located in the middle of this flexible sieve body (1 ), which has three pieces in the sieve machine mechanism, moves these three flexible sieve bodies (1 ), providing maximum vibration and performing the sifting process efficiently. The flexible sieve body (1 ) can transmit the vibration received from the vibration motor (3) much more efficiently, to the flexible sieve surface (2) that it surrounds, with its flexible structure. The sieving process takes place when the vibration applied by the vibration motor (3) at the appropriate frequency reaches the flexible sieve surface (2). The flexible sieve surface (2) has an elastic surface just like the flexible sieve body (1 ), with the rubber that forms its structure, and this flexibility ensures that the sieving process is much more efficient. While the coarse material to be sieved remains on the flexible sieve surface (2); fine materials can be sieved. The sieve machine can perform both dry and wet sieving with its flexible sieve surface (2).

[0034] The vibration motor (3) is the part that produces the sieving vibration needed by the sieve machine. The vibration motor (3) positioned at the center of the flexible sieve body (1 ), which has 3 pieces on the sieve machine, is the main element that enables the classification and sieving process. Electricity is used as the power source via the power cable (5).

[0035] The sieve machine can sieve both on land and on water. It comprises an inner tube (4) that allows the sieve machine to float in water and can increase the effectiveness of the sieving mechanism in the terrestrial environment. With the inner tube (4), the system can be easily floated in the pool, lake or sea, while on the other hand, it can be positioned on the water and thus remain stable on the water surface when long-term classification and sieving is required. In particular, it can be used effectively for the sieving and classification of alluvial sands found in water. Flexible sieve bodies (1 ), flexible sieve surfaces (2) and vibration motor (3) built into each are located on the inner tube (4).

[0036] The energy of the vibration motor (3) is provided by electrical energy. This energy transfer takes place via the power cable (5) over the socket.
