CROSS-REFERENCE TO RELATED REGISTRATION

[0001] The present application claims priority over US patent application number 62 / 331423, filed on May 3, 2016, which is hereby incorporated herein in its entirety by reference. BACKGROUND

[0002] Rotary equipment, including rotary screens, is used as a mechanical sieve. The screening capacity of rotary equipment generally depends on the essentially circular motion and / or vibration of the equipment. Rotary equipment can be adapted to screen both wet and dry materials. More specifically, rotary screens can be used to screen many materials, including fracking sand, resin-coated sand, ceramic propellants, activated carbon, fertilizers, limestone, petroleum coke, plastic granules, PVC powder, metallic powder, ceramic powder, roofing granules, salt, sugar, grain, and more. Rotary screens can be used in the hydrofracking, oil, construction, mining, food processing, chemical, materials science, pharmaceutical, plastics, and other industries.

[0003] Rotating equipment can include one or more sets of screens. The screens can be arranged vertically. Screens can be removable and interchangeable, allowing different sets of screens to be used for different applications and enabling the replacement of worn or damaged screens. Generally, the screens can include different mesh sizes, with the coarsest (largest mesh size) screen closest to the input and the finest (smallest mesh size) screen closest to the final output. A rotating screening device can have multiple outputs, depending on the application (e.g., one output for each screen), allowing materials that cannot pass through every screen to be discharged separately and thus separated.

[0004] An input or feeding mechanism can be located at or near the top of a rotating sieve (e.g., above or adjacent to the uppermost and coarsest sieve). As input material is introduced into the rotating sieve, rotational motion and gravity allow particles smaller than the mesh size of the sieve to move through the sieve to the next sieve plate below.

[0005] Rotating equipment may incorporate a system of eccentric weights. For example, a rotating screen may include an upper weight and a lower weight. The upper weight may be coupled to a motor, causing it to rotate in a plane close to the center of the assembly's mass. This can cause vibrations and movement of the screen in the horizontal plane, which may cause material fed into the screen surface to spread across the screen from the center to the perimeter or outer edges. Such movement can cause material too large to pass through the screen to be ejected and thus removed from the screen surface. A lower eccentric weight may rotate below the center of mass, creating an inclination on the screen surface. Imposing an inclination on the screen surface can cause vibrations in both a vertical and tangential plane.Such movement can cause particles smaller than the mesh size to cross the sieve surface at a faster speed and can encourage particles only slightly smaller than the mesh size to find the correct orientation to fall through the sieve, thus increasing the throughput. Horizontal or vertical movement can be amplified by spring arrangements. SUMMARY

[0006] Rotating sieve devices and components thereof are described in this disclosure.

[0007] Rotary screening devices can include trays of screens or just a single screen. The number of trays in a rotary screening device can range from one to eight, for example, although it is possible to include more trays if required for a specific application. There can be between one and four screens per tray, depending on the application. More screens can be added to each tray if needed for a particular application. In some examples, each tray can be arranged as an independent system with its own set of screens and discharge. Each tray can have its own input, or an input can be provided with a separator to distribute input material evenly to each tray. The screens of each tray can be arranged vertically or stacked on top of each other.The screens can have different mesh sizes, with the coarsest (largest mesh size) screen being closest to the input and the finest (smallest mesh size) screen being closest to the output. A rotating screen (or tray system) can have multiple outputs, depending on the application (e.g., one output for each screen or tray), so that materials that cannot pass through every screen or tray can be discharged and thus separated. Each rotating screen can have a single input that feeds all trays. The single input can be equipped with one or more separators to create multiple inlets, one inlet per tray, so that the flow of input material can be distributed evenly to each tray.The rotating motion of the machine can be used as the mechanism by which the flow of input material is evenly distributed to the specific inlet for each floor.

[0008] A separating device according to the present disclosure can additionally serve as a container for accumulating input material to be distributed to the bottoms of the rotating sieve. The separating device can include a lower section that prevents input material from exiting the bottom of the separating device. The separating device can include various openings (e.g., one for each bottom) along a side wall. When the rotating sieve is in operation, rotary motion, including horizontal or lateral motion components, can force the input material to be thrown through an opening along the side wall of the separating device. If the direction of motion changes, the input material can be thrown out from a different region of the side wall.During operation, the machine can move in any direction for approximately equal periods of time, ensuring that roughly the same amount of input material is thrown from each section of the separating device's side wall and onto the corresponding tray of the rotating screen. This maintains a uniform distribution of input material to each tray. List of characters

DETAILED DESCRIPTION

[0010] The following detailed description refers to the accompanying drawings, which form an integral part thereof. In the drawings, similar symbols typically denote similar components, unless the context indicates otherwise. The illustrative embodiments described herein are not intended to be limiting. Other embodiments may be used and further modifications made without departing from the basic idea or scope of the subject matter presented here. It is understood that the aspects of the present disclosure, as generally described herein and illustrated in the figures, may be arranged, substituted, combined, and designed in a wide variety of different configurations, all of which are expressly considered and form part of this disclosure.

[0011] This disclosure generally relates to sieving, separating, and screening equipment. Some examples of this disclosure relate to rotary equipment, rotary screening devices, and components thereof. Some examples relate to rotary screening devices having multiple platforms, each platform containing multiple screens and components thereof. Other examples relate to input components for rotary screening devices, especially a separating device for separating or distributing input material, the separating device also serving as a receptacle for holding input material before it is distributed by the separating device. This receptacle may serve as a stone box to reduce wear on the separating device and the rest of the inlets.

[0012] A separating device according to the present disclosure can serve several purposes. A separating device can distribute input material to one or more trays of a rotary screening machine. A configured separating device can also serve as a container for input material awaiting distribution to the one or more trays of the rotary screening machine. Input material can enter the separating device from an upper end. The separating device can include a lower surface. The lower surface can be solid, thus preventing material from exiting through the underside of the separating device. The lower surface can allow some input material to accumulate in the separating device during operation. The separating device can include one or more side walls defining a cylindrical circumference or rim.The number of side walls can depend on the shape of the bottom surface and / or the separating device as a whole. For example, a separating device with a circular bottom surface may have a continuous side wall that defines a cylindrical circumference or rim.

[0013] The circumference can include one or more openings. The number of openings in the circumference can correspond to the number of trays in a rotating screen. For example, if a rotating screen contains six trays, the side wall of the screen can include six openings. The openings can have the same area and can be equidistant from each other.

[0014] The opening may include slots (or holes or other voids) large enough to allow input material to flow through. Slots may restrict input material but do not prevent it from flowing through the side walls of the separator. The slots may prevent the input material from flowing back, creating the stonebox effect. As input material accumulates in the separator, the rotating motion throws the product through the slots with an even distribution between the bottoms. The size of the slots may vary depending on the size of the product being screened. In some examples, slots may range from about 0.25 inches to about 1 inch in height. The openings may also include overflow windows, which allow input material to flow through during a surge of input material being introduced into the separator.In this way, the overflow window can prevent a blockage of input material or a slowing of the flow of input material through the separating device.

[0015] When a rotary screen is in operation, rotational motion, especially horizontal or lateral motion, can force the input material to be ejected or flung through openings or slots along the side wall. If the direction of motion changes, the input material can be ejected or flung through a different opening or slot along the side wall of the screen. In this way, input material can flow through the screen in a manner that distributes it to different levels of the rotary screen. During operation, the rotation of the screen can move in each direction for approximately equal periods of time, thus enabling approximately equal amounts of input material to be thrown from each side of the screen and onto the corresponding level of the rotary screen.In this way, an even distribution of input material can be maintained on each floor.

[0016] Fig. Figure 1 illustrates an example separating device 100 in accordance with the present disclosure. The separating device 100 can a side wall 150 , Abundance window 120 , slots 140 and a lower surface 130 include. It should be noted that from the perspective of Fig. 1 the lower surface 130 It can only be seen through slits. Alternatively, the separating device can be used. 100 an upper surface 110 include, which may be useful for the separating device 100 to connect, for example, an input material or an inlet hose. The upper surface 110 can be used to create separating devices 100to couple to other parts of a rotating sieve device, such as a frame. For this purpose, the upper surface can be 110 a female recording 111 a coupling mechanism that can accommodate a male end of a coupling mechanism, such as a nut and bolt, and / or other mechanisms known to a person skilled in the art. Different slot patterns 140 can be used depending on the specific composition of the input material. Slit patterns 140 can be installed directly into the side wall 150 be integrated.

[0017] Input material can pass through the upper section of the separating device 100 enter. In the separating device from Fig. 1 This entry corresponds to the circular hole in the upper surface 110 Input material can accumulate on the floor surface. 130 deposit and accumulate, so that all or parts of the inside of the separating device100 can be filled with the input material. If the separating device 100 When coupled to a rotating sieve device, the rotating movement of the rotating sieve device can move the input material that is located inside the separator device. 100 has accumulated, causing it to pass through the slots 140 and / or excess window 120 to be ejected. If the rotating motion changes during operation of the rotating sieve device, input material can be ejected from different slots. 140 and / or excess windows 120 along the side wall. During operation, the rotating motion can cause approximately the same amount of input material to be ejected from each opening. Since each opening of the separating device 100Each tray of the rotating separator can hold approximately the same amount of input material to be sieved, as each tray can correspond to a different tray of the rotating separator. 100 out of Fig. 1 contains six openings (each of which is a slot) 120 and an abundance window 140 ), which can enable the separating device 100 out of Fig. 1 can be used in a rotating sieve device with six trays. This can be considered a 1The term "6-separating device" is used. A person skilled in the art will understand that a separating device with a different number of openings can be used in a rotating sieve with a different number of trays. For example, a separating device with two openings can divide the input material into two trays, a separating device with four openings can divide the input material into four trays, and a separating device with eight openings can divide the input material into eight trays.

[0018] A rotating sieve device may include an inlet door to access the openings of the separating device. 100 to couple to the bottoms of the rotating sieve device. Fig. Figure 2 illustrates an example of an entrance door 200 with an exemplary separating device attached to it 100 The entrance door 200 can have a variety of inlets 220 (whose outer sides in Fig. (2 are shown) include each entrance door. 220 can lead to another floor 210 - 215 each bottom can contain one or more sieves. Each opening (including slots) 120 ) the separating device 100 can communicate with an entrance 220 stand and correspond to it, so that the number of openings in the separating device 100 the number of entrances 220 in the entrance door 200 corresponds to and the number of inlets 220 in the entrance door 200 the number of floors 210 - 215 in the rotating sieve device. In some examples, there may not be a separate inlet component that is separated by the separating device. 100 to the upper floor 210 This leads to the inlet material being fed directly from the separating device. 100 to the upper floor 210 fall. Inlets 220Input material can be introduced through the corresponding openings (via slots). 120 ) was thrown into the separating device 100 to the corresponding soil 210 - 215 guide or direct. The rotating motion of the rotating sieve device can ensure that approximately the same amount of input material is drawn from the separator. 100 via appropriate inlets 220 to any floor 210 - 215 is being conducted.

[0019] Fig. Figure 3 is a perspective cross-sectional view of the example entrance door. 200 out of Fig. 2. The perspective cross-sectional view from Fig. Figure 3 helps to illustrate how inlets 220 the openings (the slots) 120 exhibit) the separating device 100 to the floors 210 - 215 couple. In Fig. 3. The opening of the separating device can be opened. 100 , which belong to the upper floor 210This does not correspond to an inlet, but rather the inlet material can fall directly from the separator opening to the upper bottom. Each of the other openings of the separators... 100 corresponds to their own entrance 220 and every entry 220 corresponds to its own base. When a rotating separator is in operation, input material can be drawn from openings through slots. 120 The material is thrown as described previously, so that approximately the same amount of input material exits each opening. In this way, the input material can be fed through inlets. 220 to any floor 210 - 215 be distributed so that each floor 210 - 215 receives approximately the same amount of input material.
