Abstract
Description
Technical Field
[0001] This utility model relates to the field of slag sorting, specifically a vibrating screen for slag processing and sorting. Background Technology
[0002] The slag processing and sorting vibrating screen is a key piece of equipment for particle size classification and component separation of industrial slag (such as coal combustion slag, gasification slag, and waste incineration slag). Its core function is to achieve efficient screening of materials of different particle sizes in slag through mechanical vibration.
[0003] In the existing technology, during the use of vibrating screens, the filter screen (screen) is a core vulnerable component, and its quality directly affects the screening accuracy, production efficiency and equipment stability. However, the long-term impact and friction of hard materials such as slag on the screen will cause the mesh to gradually enlarge, destroying the grading effect. Therefore, the filter screen needs to be replaced regularly. In order to facilitate quick replacement of the filter screen, this utility model proposes a vibrating screen for slag processing and sorting. Utility Model Content
[0004] The purpose of this utility model is to provide a vibrating screen for slag processing and sorting in order to solve the problems mentioned in the background.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a slag processing and sorting vibrating screen, including a sorting box with a shock-absorbing spring column installed at the bottom, a vibrating motor provided at the bottom of the sorting box to provide vibration force to the sorting box, a filter screen for screening materials provided in the inner cavity of the sorting box, and a limiting mechanism provided on the sorting box for limiting the installation of the filter screen; The limiting mechanism includes a transmission unit and a support unit; The support unit is used to provide support and limit for the installation of the filter screen; The transmission unit is used to provide power for the movement of the support unit.
[0006] As a further improvement of this utility model: the support unit includes a fixing block and a limiting block; The fixing block is fixed inside the sorting box and located below the filter screen. The fixing block is used to provide support for the placement of the filter screen. The limiting block is laterally slidably installed inside the sorting box and extends to the inside of the sorting box. The limiting block is used to cooperate with the fixing block to limit the placement of the filter screen.
[0007] As a further embodiment of this utility model: the transmission unit includes a pressing rod, a positioning rod, a spring, a guide groove, and a guide rod; The pressing rod is vertically slidably installed inside the sorting box and extends to the outside of the top of the sorting box. The pressing rod is used to synchronously drive the guide groove to move vertically. The positioning rod is axially slidably installed at the top of the sorting box and passes through the pressing rod. The positioning rod is used to limit the vertical movement of the pressing rod. The spring is connected to the inside of the sorting box and the inside of the pressing rod. The spring is used to provide an upward thrust for the pressing rod after it has moved. The guide groove is opened on the pressing rod. The guide groove is used to provide a squeezing thrust for the lateral movement of the guide rod. The guide rod is fixed to the outer wall of the limiting block. The guide rod is used to synchronously drive the limiting block to move laterally.
[0008] As a further improvement of this utility model: the inner side of the guide groove matches the outer wall of the guide rod, and the outer wall of the guide groove is generally inclined.
[0009] As a further improvement of this utility model: the spacing between the fixed block and the limiting block is matched with the thickness of the filter screen, and the sorting box has an internally formed movable groove for the limiting block to enter.
[0010] Compared with the prior art, the beneficial effects of this utility model are: By setting a limiting mechanism, when the filter needs to be replaced, after the vertical movement limit of the pressing rod is released by pulling the positioning block axially, the guide rod is pushed to move laterally by applying downward squeezing force to the pressing rod. The guide rod drives the limiting block to move into the interior of the sorting box, releasing the movement limit of the filter. Then, the positioning rod is pushed to reset, so that the positioning rod is locked at the top of the pressing rod, limiting the position of the pressing rod. The above operations can be performed simultaneously to release the limits of other limiting blocks, making it easy to remove the filter. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] Please see Figures 1-3 In this embodiment of the utility model, a slag processing and sorting vibrating screen includes a sorting box 1 with a shock-absorbing spring column installed at the bottom, a vibrating motor 2 provided at the bottom of the sorting box 1 to provide vibration force to the sorting box 1, a filter screen 3 for screening materials is provided in the inner cavity of the sorting box 1, and a limiting mechanism 4 provided on the sorting box 1 for limiting the installation of the filter screen 3. The limiting mechanism 4 includes a transmission unit and a support unit; The support unit is used to provide support and limit for the installation of filter 3; The transmission unit is used to provide power for the movement of the support unit; The support unit includes a fixing block 401 and a limiting block 402; The fixing block 401 is fixed inside the sorting box 1 and located below the filter screen 3. The fixing block 401 is used to provide support for the placement of the filter screen 3. The limiting block 402 is laterally slidably installed inside the sorting box 1 and extends to the inside of the sorting box 1. The limiting block 402 is used to cooperate with the fixing block 401 to limit the placement of the filter screen 3. The transmission unit includes a pressing rod 403, a positioning rod 404, a spring 405, a guide groove 406, and a guide rod 407; The pressing rod 403 is vertically slidably installed inside the sorting box 1 and extends to the outside of the top of the sorting box 1. The pressing rod 403 is used to synchronously drive the guide groove 406 to move vertically. The positioning rod 404 is axially slidably installed at the top of the sorting box 1 and passes through the pressing rod 403. The positioning rod 404 is used to limit the vertical movement of the pressing rod 403. The spring 405 is connected to the inside of the sorting box 1 and the inside of the pressing rod 403 respectively. The spring 405 is used to provide the pressing rod 403 with an upward thrust after it moves. The guide groove 406 is opened on the pressing rod 403. The guide groove 406 is used to provide a squeezing thrust for the lateral movement of the guide rod 407. The guide rod 407 is fixed to the outer wall of the limiting block 402. The guide rod 407 is used to synchronously drive the limiting block 402 to move laterally.
[0015] In this embodiment: when the filter 3 needs to be replaced, an axial moving force is applied to the positioning rod 404, causing the positioning rod 404 to move out of the inside of the pressing rod 403, thereby releasing the vertical movement limit of the pressing rod 403. At this time, a downward pressing force can be applied to the pressing rod 403, causing the pressing rod 403 to fully enter the interior of the sorting box 1. The vertically moving pressing rod 403 will apply a compressive force to the spring 405, and simultaneously drive the guide groove 406 opened on its side outer wall to move vertically. The inclined guide groove 406 moves vertically downward, applying a compressive force to the guide rod 407, causing the guide rod 407 to drive the limiting block 402 to move laterally into the interior of the sorting box 1, thereby releasing the filter 3. Once the position is limited, an axial thrust can be applied to the positioning rod 404, causing its bottom to engage with the top of the pressing rod 403, thus limiting its vertical movement. This process is repeated to release the three limiting blocks 402 from restricting the filter screen 3, allowing it to be removed. When the filter screen 3 needs to be installed, after placing it on the upper surface of the fixing block 401, an axial thrust is applied to the positioning rod 404, causing the pressing rod 403 to move under the elastic force of the spring 405, thereby pulling the limiting blocks 402 to the upper surface of the filter screen 3. This completes the rapid limiting of the filter screen 3, achieving the purpose of quickly removing and limiting it, further improving work efficiency.
[0016] Please refer to this carefully. Figures 1-3 The inner side of the guide groove 406 matches the outer wall of the guide rod 407, and the outer wall of the guide groove 406 is inclined as a whole.
[0017] In this embodiment: with this structure, when the guide groove 406 moves downward with the pressing rod 403, the inclined guide groove 406 will give the guide rod 407 a lateral moving thrust.
[0018] Please refer to this carefully. Figures 1-3 The spacing between the fixed block 401 and the limiting block 402 is matched with the thickness of the filter screen 3, and the sorting box 1 has an internally formed movable groove for the limiting block 402 to enter.
[0019] In this embodiment: this structure allows the limiting block 402 to enter the interior of the sorting box 1 after being pulled by the guide rod 407, so that the upward movement of the filter screen 3 is not limited by the limiting block 402.
[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
