Technical Field

[0001] The utility model relates to the field of thickness screens, in particular to an ash conveying thickness screen. Background Art

[0002] Ash refers to the final product formed after the minerals in the coal undergo certain physical and chemical changes under the high temperature caused by combustion. Due to the accumulation of ash, it is necessary to clean the ash effectively and promptly. When cleaning the ash, the high-temperature slag needs to be transported to the outside. It is a necessary link for the safe operation of the equipment. When transporting the ash, an ash conveying thickness screen is required.

[0003] In the process of realizing the present invention, the inventors found that at least the following problems existed in the prior art and were not solved: during use, the traditional ash conveying thickness screen could not flatten the accumulated ash multiple times, so that the accumulated ash could not be quickly screened, and the ash accumulated together easily led to insufficient screening, the efficiency and sufficiency of the ash screening process were relatively poor, and the ash easily polluted the working environment during the conveying and screening process. Therefore, it is necessary to design a new technical solution to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to actual needs, and provide an ash conveying thickness screen to solve the technical problems that the efficiency and sufficiency of the current ash screening process are relatively poor and the ash easily pollutes the working environment during the conveying and screening process.

[0005] The top of the thickness screen mechanism is fixedly connected with the protective cover, and the top of the protective cover is provided with three threaded holes, and the three threaded holes are connected with a baffle plate through a threaded adjustment rod, one end of the threaded adjustment rod is rotatably connected to the inner wall of the threaded hole, and the other end of the threaded adjustment rod is rotatably connected to the top of the baffle plate, and the two ends of the baffle plate are slidably connected to the inner wall of the protective cover.

[0006] Preferably, one end of the conveying mechanism is fixedly connected to a first material guide plate, and one end of the thickness screen mechanism is fixedly connected to a second material guide plate. The first material guide plate is located below the second material guide plate and is one end of the length of the second material guide plate.

[0007] Preferably, one end of the protective cover is connected to a feeding auger through a through hole, the through hole is located at one end of the protective cover and communicates with the interior thereof, and the discharge port of the feeding auger is located inside the protective cover.

[0008] Preferably, the screen belt is located inside the thickness screen mechanism and is slidably connected to the inner wall thereof, and the conveyor belt is located inside the conveyor mechanism and is slidably connected to the inner wall thereof.

[0009] Preferably, one end of the two sprockets is fixedly connected to the other end of the two rotating shafts respectively, and the two ends of the chain are engaged with the outside of the two sprockets.

[0010] Preferably, one end of the vibration mechanism is fixedly connected to a driving motor, an output end of the driving motor is fixedly connected to a driving shaft, and an exterior of the driving shaft is fixedly connected to a cam.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model combines the thickness screen mechanism and the vibration mechanism. When the ash is being transported, the ash is first transported to the inside of the protective cover by the feeding auger. At this time, the ash will fall onto the screen belt, and then the driving motor drives the screen belt to transport the ash through the rotating shaft. When the ash passes through the baffle plate, the baffle plate will flatten the accumulated ash for multiple times, so that the accumulated ash can be quickly screened, avoiding the phenomenon that the ash cannot be fully screened due to accumulation of ash.

[0013] The vibration mechanism generates vibration, so that the fine slag in the ash falls from the screen onto the conveyor belt, and the sprocket and chain cooperate to drive the conveyor belt to rotate, thereby transporting the screened ash, improving the efficiency and sufficiency of the ash screening process;

[0014] When the ash is being transported, it enters the protective cover for the first time, at which time the protective cover will block the dust generated when the ash falls. When it enters the conveyor belt for the second time, the support frame will block the dust during the falling process, thereby preventing the ash from polluting the working environment during the transportation and screening process.

[0024] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0025] Example 1: A slag conveying thickness screen, see Figures 1 to 5, including a conveying mechanism 1, one side of the thickness screen mechanism 2 is fixedly connected to a driving motor 21, and both ends of the conveying mechanism 1 and the thickness screen mechanism 2 are rotatably connected to a rotating shaft 22, a screen belt 23 is installed on one group of rotating shafts 22, and a conveyor belt 12 is installed on the other group of rotating shafts 22, the screen belt 23 is located inside the thickness screen mechanism 2, and is slidably connected to its inner wall, the conveyor belt 12 is located inside the conveying mechanism 1, and is slidably connected to its inner wall, wherein the other ends of the two rotating shafts 22 are connected to a chain 14 through a sprocket 13, one end of the two sprockets 13 is respectively fixedly connected to the other end of the two rotating shafts 22, and the two ends of the chain 14 are meshed with the outside of the two sprockets 13, and the bottom of the thickness screen mechanism 2 is fixedly connected to a vibration mechanism 3, and the top of the protective cover 4 is provided with three threaded holes 41, and the three threaded holes 41 are connected to a baffle plate 43 through a threaded adjusting rod 42, and one end of the threaded adjusting rod 42 is screwed to the inner of the threaded hole 41 The slag is then fed to the conveyor belt 12 and the slag is fed to the conveyor belt 12 via the feed screw 45. The slag is fed to the conveyor belt 12 and the feed screw 45 is fed to the conveyor belt 12 via the feed screw 45.

[0026] The upper surface of the conveying mechanism 1 is connected to the thickness screen mechanism 2 through the support frame 11. The top of the thickness screen mechanism 2 is fixedly connected to the protective cover 4. When the ash is conveyed, it enters the protective cover 4 for the first time. At this time, the protective cover 4 will block the dust generated when the ash falls. When it enters the conveyor belt 12 for the second time, the support frame 11 will block the dust during the falling process, thereby preventing the ash from polluting the working environment during the conveying and screening process.

[0027] For details, see Figure 2 One end of the conveying mechanism 1 is fixedly connected to a first guide plate 15, and one end of the thickness screen mechanism 2 is fixedly connected to a second guide plate 24. The first guide plate 15 is located below the second guide plate 24 and is one end of the length of the second guide plate 24, so that the ash on the thickness screen mechanism 2 and the ash on the conveying mechanism 1 can be collected separately, thereby avoiding the ash from being mixed together again during the collection process.
