Description

Technical Field

[0001] The present application relates to the technical field of bulk material conveying and distributing devices, and in particular to a material distributing device of a rotary hook-tooth type debris remover. Background Art

[0002] In thermal power, steel, chemical, metallurgy and other industries, various bulk minerals such as coal, coke, ore, limestone, etc. are used. Before mining or transporting these bulk materials to the workshop, they need to be screened to remove the impurities mixed in them.

[0003] In the process of removing impurities from bulk minerals, a rotary hook-tooth impurity remover is often used. However, in actual use, the rotary hook-tooth impurity remover often causes concentrated material delivery, which results in concentrated material entry. This not only causes material stagnation and blockage at the inlet and other locations, thus reducing the efficiency of the impurity remover, but also causes the accumulated materials at the bottom to be unable to be hooked up and lose the impurity removal function.

[0004] To this end, the present application provides a material equalizing device for a rotary hook-tooth type debris remover, so that the material passes through the rotary hook-tooth type debris remover evenly, thereby improving the debris removal efficiency. Utility Model Content

[0005] The purpose of the present application is to solve the problems existing in the prior art and to propose a material equalizing device for a rotary hook-tooth type debris remover.

[0006] In order to achieve the above purpose, this application adopts the following technical solutions:

[0007] A material equalizing device for a rotary hook-tooth debris remover comprises a flow guide gallows rotatably mounted on a debris remover housing, a flow guide regulating column is fixed on the flow guide gallows, a side wall of the flow guide regulating column is connected to the debris remover housing via a tension spring, a triangular flow divider is provided at the lower end of the flow guide regulating column, and the flow divider can be adjusted vertically.

[0008] Preferably, the diverter includes two symmetrically arranged diverter plates and a connecting plate, and the two diverter plates and the connecting plate are welded into a triangle.

[0009] Preferably, a plurality of groups of straight grooves are symmetrically provided at the lower end of the diversion adjustment column, through holes corresponding to the straight grooves one by one are provided on the connecting plate, and bolts are provided between the straight grooves and the through holes.

[0010] Preferably, a flared pull plate is welded to the side wall of one end of the diversion adjustment column close to the diversion gallows, and two hanging holes are symmetrically provided on the pull plate. The hanging hole is hooked with one end of the tension spring, and the other end of the tension spring is hooked with a pull rod. The connecting rod passes through the side wall of the debris remover chassis and a locking nut is threadedly installed on the end thereof, and the locking nut rests on the side wall of the debris remover chassis away from the tension spring.

[0011] Preferably, it further includes a buffer stop fixed on the debris remover box body, and the buffer stop abuts against the side wall of the diversion adjustment column facing the pull rod side.

[0012] Preferably, the diversion adjustment column is V-shaped.

[0013] Compared with the prior art, the present application provides a material equalization device for a rotary hook-tooth debris remover, which has the following beneficial effects:

[0014] 1. During use, under the action of the triangular diverter, the mineral bulk material is diverted to both sides, and the material flow is regularized into a flat shape, producing a loosening effect, so that the material passes through the rotary hook teeth of the hook-tooth separation device of the debris remover more evenly. This not only avoids the blockage and retention of the material, improving the impurity removal efficiency; but also the material is evenly dispersed, avoiding the accumulation of the material and preventing the bottom material from being hooked, thereby reducing the impurity removal effect.

[0024] The following will combine the appendix in the embodiments of the present applicationFigures 1-6 To clearly and completely describe the technical solutions in the embodiments of this application, it is obvious that the described embodiments are only a part of the embodiments of this application, rather than all the embodiments.

[0025] To solve the problems existing in the prior art, this embodiment provides a material equalizing device for a rotary hook-tooth type debris remover, which includes a diversion truss 3 rotatably installed on the debris remover box body 1. A diversion adjustment column 4 is fixed on the diversion truss 3. The side wall of the diversion adjustment column 4 is hooked to the debris remover box body 1 through a tension spring 7. A triangular diverter 6 is provided at the lower end of the diversion adjustment column 4, and the diverter 6 can be vertically adjusted in position.

[0026] Details of the principle of this solution:

[0027] A material equalizing device for a rotary hook-tooth type debris remover, including:

[0028] A diversion truss 3 rotatably installed on the debris remover box body 1. The diversion truss 3 includes two lifting lugs, a bottom plate, and a rib plate, which are continuously welded between adjacent workpieces. A rotating shaft is inserted between the two lifting lugs. There are two hanging lugs on the top wall of the debris remover box body 1 that cooperate with the lifting lugs, and through holes that cooperate with the rotating shaft are provided on the hanging lugs. Plug pins or limit nuts are installed threadedly at both ends of the rotating shaft. During installation, the rotating shaft passes through the hanging lugs and the lifting lugs, and the rotating shaft is limited by the plug pin or the limit nut, so as to limit the diversion truss 3 on the bottom wall of the debris remover box body 1, realizing the rotational installation of the diversion truss 3 on the top wall of the debris remover box body 1.

[0029] A diversion adjustment column 4 is welded and fixed on the bottom plate of the diversion truss 3, and a triangular diverter 6 is provided at the lower end of the diversion adjustment column 4. Two tension springs 7 are symmetrically hooked on the side wall of the diversion adjustment column 4 close to the diversion truss 3, and the other ends of the two tension springs 7 are hooked to the side wall of the debris remover box body 1 in the opening direction of the debris remover box body 1 through the tension springs 7. Under the action of the tension spring 7, the diversion adjustment column 4 tends to deflect towards the opening direction of the debris remover box body 1, so that the bottom end of the diverter 6 abuts against the bottom wall of the feed inlet of the debris remover box body 1.

[0030] The diverter 6 can be vertically adjusted in position to be applicable to different feeding speeds and material separation and screening speeds.

[0031] During use, the material equalizing device is installed at the feed inlet of the debris removing machine housing 1. Under the action of the tension spring 7, the diverter 6 abuts against the bottom wall of the feed inlet of the debris removing machine housing 1. When mineral bulk materials are put in, the materials rotate along with the belt and are transported to the rotary hook tooth type debris removing machine for impurity removal. Under the action of the triangular diverter 6, the mineral bulk materials are diverted to both sides, and the material flow is regularized into a flat shape, generating a loosening effect, so that the materials can pass through the rotary hook teeth of the hook tooth separation device of the debris removing machine more evenly. The rotating hook teeth will hook out sundries such as wooden blocks, stones, rags, hemp ropes, and blasting wires in the coal flow and carry them to the other side for discarding, thereby achieving the purpose of impurity removal. This not only avoids the blockage and retention of materials, improving the impurity removal efficiency, but also evenly disperses the materials, preventing the bottom materials from being unable to be hooked due to material accumulation and reducing the impurity removal effect.

[0032] Preferably, during use, multiple groups of material equalizing devices are provided to make the material dispersion more uniform.

[0033] In this embodiment, the diverter 6 is arranged on the diversion truss 3 through the diversion adjustment column 4. Under the connection of the tension spring 7, it can also deflect relatively when impacted by materials, offsetting the impact brought by the material operation. It also avoids the mineral bulk materials being stuck and piled up on the diverter 6 under rigid fixed installation.

[0034] In a further embodiment of this solution, a specific diverter 6 mechanism is provided: the diverter 6 includes two symmetrically arranged diverter plates 601 and a connecting plate 602. The two diverter plates 601 and a connecting plate 602 are welded into a triangle. Thus, a triangular structure is formed to achieve the purpose of material diversion. The vertical dimension of the connecting plate 602 is smaller than that of the diverter plate 601, so that the bottom end of the connecting plate 602 is suspended. When the bulk materials fall between the two diverter plates 601, they can leak out from the bottom end of the connecting plate 602.

[0035] In a further embodiment of this solution, a specific structure for vertical position adjustment of the diverter 6 and the diversion adjustment column 4 is provided in this embodiment: multiple groups of straight grooves are symmetrically arranged at the lower end of the diversion adjustment column 4, and through holes corresponding to the straight grooves one by one are provided on the connecting plate 602. Align the through holes on the connecting plate 602 with the straight grooves on the diversion adjustment column 4 and fasten the two with bolts, thereby realizing the firm installation of the diverter 6 on the diversion adjustment column 4. And different height positions of the through holes and the straight grooves can realize the adjustment of the height interval between the diverter 6 and the conveyor belt in the debris removing machine. Installed and connected by bolts, it is convenient for disassembly and assembly and easy for maintenance.

[0036] In a further embodiment of the present scheme, a specific structure is provided in which the flow guide adjustment column 4 is connected to the debris remover housing 1 via the tension spring 7: the flow guide adjustment column 4 is welded with a flared pull plate 5 on the side wall near one end of the flow guide gallows 3, and two hanging holes are symmetrically arranged on the flared end of the pull plate 5, the hanging hole is hooked with one end of the tension spring 7, and the other end of the tension spring 7 is hooked with a pull rod 8, the connecting rod passes through the side wall of the debris remover housing 1 and a locking nut is threadedly installed at the end, and the locking nut is against the side wall of the debris remover housing 1 on the side away from the tension spring 7. Thus, the flow guide adjustment column 4, the tension spring 7, and the debris remover housing 1 are connected.

[0037] In a further embodiment of the present invention, a buffer frame 2 is further included which is fixed on the dust collector housing 1, and the buffer frame 2 is against the side wall of the diversion adjustment column 4 facing the pull rod 8. Under the action of the buffer frame 2, the diversion adjustment column 4 is lifted up, and the tension spring 7 is in an extended state, so that the diversion adjustment column 4 is always subjected to a force that deflects toward the feed inlet of the dust collector housing 1, thereby preventing the diverter 6 from being deflected backward by an excessively large angle after being impacted by the mineral bulk.

[0038] In a further embodiment of the present solution, the diversion regulating column 4 is V-shaped. The diversion regulating column 4 comprises a channel steel and two sealing plates. The channel steel is cut and bent at the middle part, and the channel steel and the sealing plates are welded together to form a V-shape. The V-shaped diversion regulating column 4 has a better force-bearing effect when bearing impact loads than the straight diversion regulating column 4.

Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and application concept of the present application, which should be covered by the protection scope of the present application.
