DESCRIPTION

VIBRATED SIEVE MECHANISM

The Related Art

The invention relates to vibration driven sieves used in various sectors for sieving, separation and filtering.

The invention particularly relates to vibration sieves of increased efficiency used in mining, ceramic, coal, sand, gravel, chemical, food, plastic sectors for purpose of sieving, separation, removal of dust, dehydration, removal of sludge and filtering.

Background of the Related Art

Various vibration sieve embodiments have been developed for use in mines, ceramic, coal, sand, gravel, chemical, food, plastic sectors for purpose of sieving, separation, removal of dust, dehydration, removal of sludge and filtering wherein raw materials are processed and made ready for use or for next process. The action of sieving the material put on the said vibration sieves is provided by means of giving vibration to the sieve whereon the material to be sieved is located. It is possible to produce vibrated sieves in different shapes and working techniques. Particularly, some developments have been tried to increase the actions such as sieving.

One of such developments is the Kroosher system developed by "Kroosh Technologies Ltd", which is sieve surface supported chassis consisting of multi-frequency adapters made of steel and elastomeric materials. Non-linear vibration is produced in axial direction by use of non-linear characteristics of shear stress/strain curves of elastomers of multi-frequency adapters. The said Kroosher system of Kroosh Technologies makes impact on the sieve surface from the bottom (impact mode) and impacting movement is transferred to multi-frequency vibrated sieve surface. This extreme impact motion shortens life of sieve surface/surfaces and sieve surface support chassis and despite the fact that other characteristics are very good, removes its economical feature. ₂ 2009/000058

In Kroosher system, although multi-frequency adapters are isblated from sieve machine body by means of elastomer parts, sieve surface (sieve eyelet) is fixed to sieve machine from starting and ending points. Forcing the Kroosher system isolated from sieve machine body together with sieve surface fixed to the body and forcing motion of 3-10 mm limits the motion/vibration of Kroosher, destroys sieve surface and sieve surface support chassis in a short time period and the energy required to given to the material to be sieved is wasted since the energy of multi-frequency adapters is absorbed by fixed edges, and thus energy consumption is increased too much and energy efficiency decreases.

The feeding and discharging sides of the sieve surfaces of Kroosh Technologies vibrate with single frequency too low vibration. For that reason, feed and discharge problems occur.

During operation, problems such as losing characteristics due to heating arising from vibration frequency and amplitude of adapter elastomeric materials may occur in some embodiments. Due to efficiency loss arising from heating, operating frequency can be limited to upper limit of 51-52 Hz and amplitude to maximum 6 mm, and thus desired operating is provided.

Another similar machine/mechanism type is disclosed in utility model application no. TR 200103007 by "MUZER MAKiNE SANAYi VE TiCARET - ZOZEF MUZMUZ". The said invention is a scrapping sieve system. The invention is scraping sieve system providing small field of operation by combining scraping band and following dust sieve features within its body, providing sieve of dust remained between leaves upon partial opening of komatya conveyed through scraping sieve as a result of staying in vibration frequency for long time and providing decrease in rate of cracks that might occur in komatya opening machine, subjecting tobacco to two sieving operation along sieve length because of 2 phased operation, providing sieve of scrapped komatya on clean sieve surface by help of roof system and preventing stocking of komatya which might occur due to height of komatya to increase cumulatively, and thus providing the most effective dust sieving operation and minimizing dust level within the rofl formed at the end of the operation by help of dust conveying system to dust chamber via side ducts.

The disadvantages of the former related art and utility model or patent developments in the related are can be listed as follows.

> Non-sieved raw material mixes with the product under the sieve during sieving.

> Energy consumption is too much and energy cannot be used effectively.

> Effective adjustment cannot be made when it is required to achieve optimum capacity and efficiency relations for sieve of some metals. > Change of sieve surfaces takes too much workmanship.

> Cracks and breaking occur on the body due to too much vibration on machine body. In addition, such problem of the body also causes noise pollution.

> Gravity cooling becomes necessary due to heating of the machine engine.

Detailed Description of the Invention

The invention particularly relates to vibration sieve mechanisms (1) of increased efficiency used in mine, ceramic, coal, sand, gravel, chemical, food, plastic sectors for purpose of sieving, separation, removal of dust, dehydration, removal of sludge and filtering.

Figure 1 is a perspective front view of the vibrated sieve mechanism (1) of the said invention. The said vibration sieve mechanism (1) consists of chassis (20), chassis feet (202) and a sieve body (12) connected onto the said chassis (20) by springs (18) from the chassis connection (201) parts and located on the said springs (18). Sieve frame (13) is located on the upper surface of the said sieve body (12). The sieve body (12) is connected to wings (121) located on side parts and connected to upper port of the sieve body (12) by engine connection bridge (11). Vibration engines (10) are located on the said engine connection bridge (11). A pool area (15) is located on the said sieve frame (13) where the sieve (16) is located. The U-shape pool area (152) and pool edges (151) are located in the inner part of the wings (121) located on side parts of the sieve body (12). In some cases, rubber sealing member (14) is located in parallel and in stripes on the said pool edges (151). The said sieve (16), preferably in the form of wire meshes, is fixed to the pool edges (151) by means of magnets (17). A chamber (21) where the sieved raw material is collected, is located in a manner it is under the sieve body (12) particularly under the sieve (16). Figure 2 is a perspective view of slope adjustment mechanism (19) of the vibrated sieve mechanism (1) of the said invention. The said slope adjustment mechanism (19) is located on both chassis feet (202) corresponding to the edge so as to raise the sieve body (12) from this edge. Slope adjustment mechanism (19) consists of slope adjustment perpetual screw (191) and slope fixing screw (192). The said slope adjustment perpetual screw (191) is located between the chassis connection (201) and chassis foot (202).

Figure 3 is a perspective front view indicating sieve body (12) and sieve frame (13 ) of the vibrated sieve mechanism (1) of the said invention. Adapters (132) are located in lower parts of the said sieve frame (13) to transmit vibration and oscillation to some areas. The said adapters (132) contains a vibration spindle (131) in the centre and an isolation disk (133) in upper part.

The vibration generated when the vibration engine (10) indicated in figure 1 runs is transmitted to the sieve body (12) by engine connection bridge (11). The vibration generated by the vibration engine (10) is in the form of multi-directional oscillations. Spring (18) is located onto chassis connections (201) where the sieve body (12) of the chassis (20) is connected, that is on each chassis foot (202). Transmission of the generated vibration to chassis (20) is prevented by the said springs (18). Thus the springs (18) absorb the vibration and increases life of vibration sieve mechanism (1). The cracks and breaking occurring on the said chassis (20) by effect of constant vibration are eliminated. In addition, having this vibration absorbing system containing springs (18) provides obtaining the desired vibration on the sieve body (12) with the least energy consumption. Besides, vibration absorbing system containing springs (18) located between each chassis foot (202) and sieve body (12) located on the said chassis feet (202) provides silent operation of the vibration sieve mechanism (1). The vibration and oscillation motions transferred by the vibration engine (10) by means of engine connection bridge (11) provides sieving the raw material or material located on the sieve (16) in the desired size.

The sieve (16) is selected according to the size of the raw material intended to be obtained. The selected sieve (16) is located on the sieve frame (13) located on the upper surface of the sieve body (12). After the said sieve (16) is located in this manner, the sieve body. (12) is fixed to the pool edges (151) from edge parts by means of magnets (17). The magnets (17) allow replacement of sieve (16) as per material type even when the vibration engines (10) in operating position. The said sieve frame (13) consists of vibration spindles (131) adapters (132) containing vibration spindles (131) and isolation disks (133) onto which the adapters (132) are fixed. The driving power received from the vibration engine (10) is transmitted to vibration spindles (131) by help of the said adapters (132). The vibration spindles (131) distribute the received vibration and oscillation homogenously onto all sieve frames (13). While the vibration sieve mechanism (1) produces expected non-linear, irregular, chaotic, multi-frequency vibration, it also prevents blocking in sieve (16) eyelets to which the vibration is transmitted as well as adherence of materials onto the surfaces. Meanwhile, the isolation disks (133) decrease the occurring friction as they are made of elastomeric material. Thus, overheating does not occur since the friction between sieve frame (13) and adapters (132) has decreased. Therefore, gravity cooling is not needed. In this way, extra cooling energy cost is eliminated.

Pool edges (151) and U-shape U pool areas (152) are located in the inner surface of the wings (121) of the sieve body (12). Not sieved materials are collected in this U pool areas (152). In addition, the sieve (16) is fixed to this pool edges (151) on the sieve body (12) by means of the magnets (17). The sieve (16) used here can be of wire mesh made of polyester or metal material. When the sieve (16) made of polyester material is not used, rubber sealing member (14) is mounted to the pool edges (151).

The sieved raw material or material is accumulated in a chamber (21) located under the sieve frame (13). The materials remaining after sieving are accumulated in the said U pool area (152). The said rubber sealing member (14) as understood from its name, prevents pouring of the raw materials of the size not sieved at the sieve (16) into the chamber (21) from the pool area (15). Slope of the desired angle depending on the type of the material to be sieved can be provided for the sieve body (12). In order to provide this slope, slope adjustment mechanism (19) located on both upper chassis feet (202) is used. Functioning as a lever jack, the slope adjustment mechanism (19) can lower and raise the sieve body (12) from one edge. The desired slope is provided by lowering or elevating the slope adjustment perpetual screw (191) to perform this action and then it is passed through the slope fixing screw (192) to fix it. Thus, sieving efficiency, raw material capacity and sieving quality of the vibration sieve mechanism (1) can be increased.

The spring (18) suspension mechanism performing isolation function between the said sieve body (12) and chassis foot (202) is a steel spring, vulkollan, elastomeric material and similar stroke absorbing member.

The protection area of this application has been specified under claims and cannot be limited to the descriptions only given as sampling above. It is clear that any innovation can be provided by a person skilled in the related art by use of the similar embodiments and/or can also apply this embodiment in other areas for similar purposes used in the related art. Therefore, it is also clear that such embodiments lack of innovation criteria.
