Description

TECHNICAL FIELD

[0002] The medium draining screen is mainly used for medium draining, dewatering and desliming, and can efficiently treat fine coal dewatering, desliming and medium draining in the washing process of the coal industry. The medium draining screen is driven to vibrate by a vibrating mechanism, so that the material forms a particle accumulation layer on the screen surface. The larger particle material stays above the screen surface to form a slurry layer, and the smaller particle material enters the screen bottom through the screen hole. The filter medium (such as a fine screen or a filter cloth) placed on the screen surface allows the water to be discharged through the screen hole, realizing solid-liquid separation.

[0003] The screen surface of the medium draining screen can be an arc screen plate surface. In use, the vibrating mechanism drives the arc screen plate surface to vibrate, and the material is uniformly fed into the screen surface and moves under the dual action of centrifugal force and gravity. Due to the arc shape of the screen surface, the material forms continuous jumping and tumbling motion on the screen surface, and different particle sizes of the material gradually separate due to the difference in motion trajectory. The large particle material moves slowly forward on the screen surface due to inertia, and finally stays on the screen surface or is discharged; and the small particle material is more likely to fall into the collecting device below through the screen hole, thereby realizing the classification and separation of the material. The arc screen plate surface of the existing medium draining screen is of an integral structure, which is very heavy and inconvenient to install. SUMMARY

Detailed Implementation

[0032] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] like Figures 1 to 6 As shown, one embodiment of the present invention provides a novel arc-shaped sieve, including: a sieve box 11, a fixing component 13, and a sieve plate 12; the sieve box 11 is provided with a plurality of supporting members 14; a plurality of sieve plates 12 are provided, each sieve plate 12 is configured with a plurality of fixing components 13, all sieve plates 12 are mounted on the supporting members 14 and fixed to the supporting members 14 by the fixing components 13, and all sieve plates 12 form a sieve mesh.

[0034] The novel arc-shaped screen provided in this embodiment includes a screen box 11, a fixing component 13, and screen plates 12. The screen box 11 provides support for the screen mesh composed of multiple screen plates 12. When the novel arc-shaped screen is used for turbulent desliming, the screen box can be connected to the support frame of the turbulent desliming screen, or it can be used as part of the support frame of the turbulent desliming screen. The screen box 11 is provided with multiple support members 14, which provide support for the screen plates 12. During assembly, the screen plates 12 are first placed on the support members 14, and then the screen plates 12 and the support members 14 are connected by the fixing component 13, thereby fixing the screen plates 12 to the support members 14. Preferably, each screen plate 12 is equipped with multiple sets of fixing components 13 to improve the stability of the screen plate 12 on the support member 14. After all the screen plates 12 are fixed, a screen mesh for screening materials is formed. The screen mesh is an arc-shaped screen mesh, and correspondingly, each screen plate 12 is also arc-shaped. By disassembling the screen into multiple screen plates 12, each screen plate 12 is lightweight, allowing each screen plate 12 to be assembled independently by a single person without the need for lifting equipment. Compared to existing technologies, the assembly of the screen is more convenient and easier to operate.

[0035] This invention utilizes the novel arc-shaped sieve provided in the embodiments of the present invention, such as... Figure 1 As shown, the novel arc screen has a first direction and a second direction that are perpendicular to each other; all the support members 14 are spaced apart in the screen box 11 along the first direction; the second direction is the flow direction of the material in the novel arc screen, and the support members 14 extend along the second direction; the screen plate 12 is respectively placed on two adjacent support members 14 on both sides along the first direction and fixed by the fixing component 13.

[0036] In this embodiment, the first direction is the width direction of the screen box 11, and the second direction is the flow direction of the material on the screen mesh. Since the screen mesh is an arc-shaped screen mesh, the second direction is an arc; the first direction and the second direction are perpendicular, that is, the tangents of the first direction and the second direction at a certain point are perpendicular to each other, while the first direction is a straight line, and its tangent is itself. For the second direction, the tangent is the best linear approximation at that point. The support member 14 has a long strip structure, preferably angle steel, and the angle steel is arc-shaped to match the screen plate 12. The angle steel has an L-shaped cross section, which has the advantages of high strength, corrosion resistance, easy processing, and low cost. All the support members 14 are spaced apart in the screen box 11 along the first direction. The two sides of the screen plate 12 in the first direction are respectively supported on two adjacent support members 14. Correspondingly, the fixing components 13 on the screen plate 12 are also distributed on both sides of the screen plate 12 in the first direction. The flow direction of the material on the screen plate 12 is the second direction perpendicular to the first direction. In this way, the material will not be obstructed by the fixing components 13 when flowing on the screen mesh, avoiding material jamming.

[0037] It is understood that in this embodiment, the support member 14 can also be other steel sections such as I-beams, or steel columns that correspond one-to-one with the sieve plate 12, all of which can achieve the purpose of supporting the sieve plate 12 in this embodiment.

[0038] The novel arc-shaped sieve provided in this embodiment of the utility model, such as Figure 1 As shown, all support members 14 are connected to the wall panel of the screen box 11; or; a crossbeam 111 extending in the first direction is fixed inside the screen box 11, at least one support member 14 is connected to the wall panel of the screen box 11, and at least one support member 14 is connected to the crossbeam 111.

[0039] In this embodiment, for the installation of the support members 14, all support members 14 can be connected to the wall panels of the screen box 11. The wall panels of the screen box 11 include a back plate 113 and two opposing side plates 114. The two support members 14 located at both ends in the first direction can be installed on the two side plates 114, and the remaining support members 14 can be installed on the back plate 113 at one end. Furthermore, supports for installing the support members 14 can be provided on the back plate 113 and side plates 114 according to actual conditions to facilitate the installation of the support members 14.

[0040] Optionally, a crossbeam 111 can be provided inside the screen box 11 to improve the strength of the screen box 11. Both ends of the crossbeam 111 are connected to two side plates 114 respectively. When the crossbeam 111 is provided inside the screen box 11, the support member 14 can be installed on the crossbeam 111 or on the wall panel. Of course, the support member 14 connected to the wall panel can also be connected to the crossbeam 111 simultaneously. For example, a section of some support members 14 can be fixed to the back plate 113, and the middle part of the support member 14 can be fixed to the crossbeam 111. Support seats for installing the support member 14 can be provided on both the back plate 113 and the crossbeam 111 to improve the stability of the support member 14.

[0041] Since the aforementioned support member 14 is preferably an angle steel, the two support members 14 located at both ends in the first direction can be directly fixed to the side plate 114 by screws or other structures without the need for a support. They have a large contact surface and strong stability.

[0042] The novel arc-shaped sieve provided in this embodiment of the utility model, such as Figures 1 to 6 As shown, the sieve plate 12 is provided with a plurality of first connecting holes 136 on both sides along the first direction, and all the first connecting holes 136 on the same side are spaced apart along the second direction; the support member 14 is provided with second connecting holes corresponding to the first connecting holes 136, and the fixing component 13 fixes the sieve plate 12 to the support member 14 by cooperating with the first connecting holes 136 and the second connecting holes.

[0043] In this embodiment, the sieve plate 12 has multiple first connecting holes 136 spaced apart along the second direction on both sides along the first direction. Correspondingly, each support member 14 has multiple second connecting holes spaced apart along the second direction and corresponding one-to-one with the first connecting holes 136. The number of fixing components 13 configured on each sieve plate 12 is the same as the number of first connecting holes 136. The first connecting holes 136 are through holes, and the fixing components 13 pass through the first connecting holes 136 and the second connecting holes to fix the sieve plate 12 to the support member 14. Optionally, the fixing components 13 can be bolts, which have a simple structure and are easy to assemble.

[0044] In use, each support member 14 needs to support multiple screen plates 12 simultaneously. All screen plates 12 are arranged in an array along the first direction and the second direction. The opposite sides of two adjacent screen plates 12 along the first direction rest on the same support member 14. The same side of all screen plates 12 along the second direction rests on the same support member 14. By supporting multiple screen plates 12 simultaneously with one support member 14, the arrangement of support members 14 can be reduced, the cost can be reduced, and the space occupied by the screen box 11 can be avoided. The weight of the screen box 11 should not be too high, which would affect its vibration effect during use.

[0045] The novel arc-shaped sieve provided in this embodiment of the utility model, such as Figure 3 and Figure 6As shown, the fixing component 13 includes a male expansion screw head 131 and a female expansion screw head 132 corresponding to each other; the female expansion screw head 132 is inserted into the corresponding first connecting hole 136 and second connecting hole, and the male expansion screw head 131 is inserted into the corresponding female expansion screw head 132.

[0046] The aforementioned fixing component 13 includes expansion screws; expansion screws are easy to install and provide good fixing effect, and are not prone to loosening due to vibration of the screen box 11. In the new type of arc screen, when screening solid and liquid materials, bolts are easily corroded by the liquid material, making them impossible to disassemble. Expansion screws, however, are durable, not easily corroded, and easy to disassemble. The expansion screw includes a male expansion screw head 131 and a female expansion screw head 132. The female expansion screw head 132 can be made of polyurethane. During assembly, the female expansion screw head 132 is first inserted into the first connecting hole 136 and the second connecting hole, and then the male expansion screw head 131 is inserted into the female expansion screw head 132. The female expansion screw head 132 is hollow inside, with a notch at the tail, and its inner diameter is slightly smaller than the outer diameter of the male expansion screw head 131. The female expansion screw head 132 deforms under external force, thereby tightening the screen plate 12.

[0047] The novel arc-shaped sieve provided in this embodiment of the utility model, such as Figure 3 and Figure 6 As shown, the first connecting hole 136 is a stepped hole. Along the axial direction of the first connecting hole 136, the first connecting hole 136 is divided into a first section and a second section. The inner diameter of the first section is larger than the inner diameter of the second section. The heads of the expansion screw female head 132 and the expansion screw male head 131 are both located in the first section.

[0048] Preferably, the first connecting hole 136 is a stepped hole, with the first section facing the working surface of the screen. During assembly, the tail of the expansion screw female head 132 is located in the second section, and the head is located in the first section; when the expansion screw male head 131 is inserted into the expansion screw female head 132, the head of the expansion screw male head 131 is also located in the first section. The first section can protect the expansion screw male head 131 and the expansion screw female head 132, preventing the material on the screen from impacting the expansion screw male head 131 and the expansion screw female head 132 during operation of the new arc screen.

[0049] The novel arc-shaped sieve provided in this embodiment of the utility model, such as Figure 3 and Figure 6 As shown, the fixing component 13 also includes a fixing block 133, which is fixed on the sieve plate 12, and the first connecting hole 136 is opened on the fixing block 133.

[0050] In this embodiment, in order to improve strength, a fixing block 133 is welded on the sieve plate 12, and the aforementioned first connecting hole 136 is opened on the fixing block 133.

[0051] The novel arc-shaped sieve provided in this embodiment of the utility model, such as Figure 3 and Figure 6 As shown, the fixing block 133 includes a first block 134 and a second block 135. The first block 134 has a first through hole 137, and the second block 135 has a second through hole 138. The first block 134 and the second block 135 are connected. The first through hole 137 and the second through hole 138 are coaxially arranged. The first through hole 137 and the second through hole 138 form a first connecting hole 136.

[0052] In this embodiment, for ease of assembly, the fixing block 133 includes a first block 134 and a second block 135. The second block 135 is welded to the sieve plate 12, and the first block 134 is welded to the second block 135. The first through hole 137 and the second through hole 138 are coaxial, and the diameter of the first through hole 137 overlaps with the diameter of the second through hole 138. The first through hole 137 and the second through hole 138 together form the aforementioned first connecting hole 136. The first through hole 137 is the aforementioned first segment, and the second through hole 138 is the aforementioned second segment.
