Description

Technical Field

[0001] This utility model relates to the field of construction waste screening, specifically to a sealing cover for a vibrating screen. Background Technology

[0002] In the process of construction waste treatment, aggregates need to be screened and graded after crushing, which is accomplished by a vibrating screen. The crushed aggregates enter the screen box of the vibrating screen through the feed inlet at the top. To prevent dust from the aggregates, the upper part of the screen box, except for the feed inlet, is sealed with a cover. In existing technology, the cover is directly connected to the screen box and fixed with bolts, so the cover vibrates along with the screen box. Due to the high vibration frequency and large amplitude of the screen box, and the fact that the screen surface width is much larger than the cover, the cover often experiences bolt loosening and cover cracking after prolonged vibration. Furthermore, the weight of the cover increases the excitation force required for the screen box vibration, leading to increased weight and energy consumption of the screening equipment.

[0003] In view of this, the present invention provides a sealing cover for a vibrating screen. By setting a separate support column and making the sealing cover body and the screen box body softly connected, the sealing cover of the present invention no longer participates in the vibration of the screen box, thereby solving the technical problem of the sealing cover being easy to loosen and crack in the prior art, while reducing the weight and energy consumption of the screening equipment. Utility Model Content

[0004] The present invention aims to provide a sealing cover for a vibrating screen to overcome the shortcomings of the prior art. The technical problem to be solved by the present invention is achieved through the following technical solution.

[0005] A sealing cover for a vibrating screen includes a sealing cover body, which is located at the upper port of a screen box body to close the upper port of the screen box body. The improvement lies in that: the sealing cover body includes a column mounted on a load-bearing base, a sealing cover frame connected to and supported by the column, and a flexible connector connecting the sealing cover frame and the screen box body, providing a flexible connection between them. The sealing cover frame is provided with a sealing cover plate for closing the upper port of the screen box body, and one of the sealing cover plates is provided with a feed inlet. The sealing cover body is supported by its own column and flexibly connected to the screen box body via the flexible connector, thus not participating in the vibration of the screen box body.

[0006] Preferably, the columns are located on both sides of the sealing cover frame, and there are a total of three sets of columns, namely the front column, the middle column and the rear column.

[0007] Preferably, the sealing cover frame is provided with a bracket, the bracket is provided with a bracket flange for connection, and the upper end of the column is provided with a column flange that mates with the bracket flange. The sealing cover frame and the column are connected through the bracket, the bracket flange and the column flange.

[0008] Preferably, a first round steel bar is provided on the outer periphery of the sealing cover frame, and a second round steel bar is provided on the outer periphery of the upper port of the screen box body. A first rubber sleeve and a second rubber sleeve are respectively provided at both ends of the flexible connector. The first rubber sleeve and the second rubber sleeve are respectively engaged with the first round steel bar and the second round steel bar to realize the connection between the flexible connector and the sealing cover frame and the screen box body.

[0009] Preferably, a plurality of skeleton beams are welded in parallel within the sealing cover frame.

[0010] Preferably, the sealing cover is disposed on the bone beam and the sealing cover frame.

[0011] Preferably, the sealing cover is connected to the sealing cover frame by bolts, and a sealing strip is provided at the connection between the sealing cover and the sealing cover frame and the skeleton beam.

[0012] Preferably, the bone beam is a channel steel welded to the opposite side of the sealing cover frame.

[0013] Preferably, the sealing cover plate has reinforcing ribs on the surface facing the screen box body, and a handle is provided on the surface of the sealing cover plate away from the screen box body.

[0014] Preferably, the sealing cover frame is welded from channel steel.

[0015] The sealing cover of this invention is supported on a load-bearing base by columns and flexibly connected to the screen box body via flexible connectors. This eliminates interference from the vibration of the screen box body, meaning the sealing cover's weight is independently supported by the columns and no longer participates in the vibration of the screen box body. This prevents the sealing cover from easily loosening bolts or cracking. Furthermore, since the weight of the sealing cover is no longer supported by the screen box body, the weight of the screening equipment is reduced, lowering energy consumption during screening operations. In addition to sealing the upper port of the screen box body, the sealing cover can also be used as a maintenance window, eliminating the need for a separate maintenance window and increasing the maintenance area. The interior of the screen box body and the screen plates can be cleaned and inspected after removing the sealing cover, facilitating internal inspection, maintenance, and cleaning of the screen box body.

[0016] Compared with existing technologies, this invention can reduce problems such as loosening and cracking of the sealing cover, and can also reduce the weight and energy consumption of the screening equipment. Attached Figure Description

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] A sealing cover for a vibrating screen includes a sealing cover body, which is located at the upper port of a screen box body 2 to close the upper port of the screen box body 2. The improvement lies in that the sealing cover body includes a column mounted on a load-bearing base, a sealing cover frame 5 connected to and supported by the column, and a flexible connector 10 connecting the sealing cover frame 5 and the screen box body 2, providing a flexible connection between them. The sealing cover frame 5 is provided with a sealing cover plate 4 for closing the upper port of the screen box body 2, and one of the sealing cover plates 4 is provided with a feed inlet. The sealing cover body is supported by its own column and flexibly connected to the screen box body 2 via the flexible connector 10, thus not participating in the vibration of the screen box body 2.

[0023] In this embodiment, the sealing cover is supported on the load-bearing base by the column and flexibly connected to the screen box body 2 by the flexible connector 10. Therefore, it is not affected by the vibration of the screen box body 2. In other words, the weight of the sealing cover is independently supported by the column and no longer participates in the vibration of the screen box body 2, thus reducing the likelihood of bolt loosening or cracking. Furthermore, since the weight of the sealing cover is no longer supported by the screen box body 2, the weight of the screening equipment can be reduced, and the energy consumption of the screening operation can be lowered.

[0024] Furthermore, the sealing cover frame 5 is welded from channel steel, and several reinforcing beams are welded in parallel within the sealing cover frame 5. Even further, the reinforcing beams are channel steel welded to opposite sides of the sealing cover frame 5.

[0025] In this embodiment, by setting a skeleton beam, the strength of the sealing cover frame 5 can be guaranteed on the one hand, preventing it from deforming during use; on the other hand, it can support the sealing cover plate 4.

[0026] Furthermore, the columns are located on both sides of the sealing cover frame 5, and there are a total of three sets of columns: a front column 1, a middle column 3, and a rear column 7. Even further, the sealing cover frame 5 is provided with a bracket 6, and the bracket 6 is provided with a bracket flange for connection. The upper end of the column is provided with a column flange that mates with the bracket flange. The sealing cover frame 5 and the columns are connected through the bracket 6, the bracket flange, and the column flange.

[0027] In this embodiment, the sealing cover frame 5 and the column are connected by a flange and bolts, which facilitates the installation, disassembly and maintenance of the sealing cover.

[0028] Furthermore, a first round steel bar 81 is provided on the outer periphery of the sealing cover frame 5, and a second round steel bar 82 is provided on the outer periphery of the upper port of the screen box body 2. A first rubber sleeve 91 and a second rubber sleeve 92 are respectively provided at both ends of the flexible connector 10. The first rubber sleeve 91 and the second rubber sleeve 92 are respectively engaged with the first round steel bar 81 and the second round steel bar 82 to realize the connection between the flexible connector 10 and the sealing cover frame 5 and the screen box body 2.

[0029] In this embodiment, the flexible connector 10 is easily and quickly connected to the sealing cover frame 5 and the screen box body 2 by means of the round steel and the rubber sleeve; by setting the round steel, it is convenient to connect the rubber sleeve on the one hand, and will not wear the flexible connector 10 on the other hand.

[0030] Furthermore, the sealing cover plate 4 is disposed on the skeleton beam and the sealing cover frame 5. Even further, the sealing cover plate 4 is connected to the sealing cover frame 5 by bolts, and a sealing strip is provided at the connection point between the sealing cover plate 4 and the sealing cover frame 5 and the skeleton beam. The surface of the sealing cover plate 4 facing the screen box body 2 is provided with reinforcing ribs, and the surface of the sealing cover plate 4 away from the screen box body 2 is provided with a handle.

[0031] In this embodiment, bolts and sealing strips ensure a good seal between the sealing cover 4 and the sealing cover frame 5 and the reinforcing beam. Furthermore, since the reinforcing beam divides the sealing cover frame 5 into multiple sections, the sealing effect of the sealing cover 4, located on the reinforcing beam and the sealing cover frame 5, is also improved. In addition, the sealing cover 4 can replace the inspection window in the prior art, eliminating the need for a separate inspection window and increasing the inspection area. That is, after removing the sealing cover 4, the interior of the screen box body 2 and the screen plate can be cleaned and inspected, thus facilitating the inspection, maintenance, and cleaning of the interior of the screen box body.
