Abstract
Description
Technical Field
[0001] The utility model relates to the field of lifting equipment, in particular to a chain bucket type elevator. Background Art
[0002] Bucket elevator is a kind of equipment for vertically conveying block materials, granules, or powdered materials. Due to its compact structure, stable and reliable operation, simple operation and maintenance, and good sealing performance, it is widely used in the grain, oil, and feed industries. With the development of the economy, the processing scale of grain, oil, and feed industries has continued to expand, and the requirements for bucket elevators have become higher and higher. The hopper scoops up the material that flows into the inlet of the barrel or scoops up the material from the bottom of the machine base, lifts it to the top through a conveyor belt or chain, and pours the material from the outlet of the bucket elevator into the subsequent chute after bypassing the head wheel. Elevators are generally divided into two types: chain drive and belt drive. Bucket elevators have a wide range of uses, and have relatively low requirements on the working environment and the characteristics and types of materials. They can lift various granular and powdery materials commonly found in the grain industry; the elevator has relatively good sealing performance. Under normal use, there will be no leakage or dust, and it almost does not cause pollution to the environment.
[0003] Elevator return refers to the phenomenon that the material is not completely discharged along the outlet at the head discharge port, and some of the material returns to the elevator base along the barrel. In actual production, if the equipment returns too much, it will inevitably reduce the production efficiency, increase power consumption and increase the material crushing rate. Especially for grains such as corn and wheat, the grains will contain light particles such as dust. Although the light particles contained in the unit volume of the transported grain will be within the preset range, as the amount of grain transported by the elevator increases, the amount of light particles temporarily stored in the elevator will also increase, and most of the light particles temporarily stored in the elevator are temporarily stored at the bottom of the elevator shell. When the light particles increase to a certain extent, dust will appear at the discharge port of the elevator along with the return of the elevator, and as the amount of grain transported increases, too many light particles will increase the light particles embedded in the bearings installed on the rotating shaft. This is the reason why the frequency of replacement of elevator bearings in the grain field is high. Therefore, it is easy to discharge the light particles temporarily stored at the bottom of the elevator and reduce the dust generated during the grain transportation to the elevator discharge port, thereby reducing the technical problems of easy damage to the equipment and frequent replacement of accessories caused by excessive light particles temporarily stored in the elevator.

[0020] Each of the guide frames 18 adopts an N-shaped structure, and each adjustment plate 17 adopts a plate-shaped structure that can slide along the inner cavity of the corresponding guide frame 18, so that the guide frame 18 can be used to limit the adjustment plate 17; the number of guide frames 18 is two, the central axis of the two driven shaft passing holes 16 and the central axis of the inner cavities of the two guide frames 18 are located in the same plane, the central axis of the adjustment hole 19 is parallel to the central axis of the inner cavity of the guide frame 18, and each guide frame 18 and the corresponding adjustment plate 17 are respectively provided with an adjustment rod 21, the number of the adjustment rod 21 is two, the adjustment rod 21 and the adjustment plate 17 are movably connected, the guide frame 18 and the adjustment rod 21 are threadedly connected, the adjustment plate 17 adopts an L-shaped structure, and the adjustment rods 21 on both sides of the adjustment plate 17 are respectively provided with limit rings 22, the limit rings 22 are connected to the adjustment rod 21, the limit rings 22 and the adjustment plate 17 are movably connected, and the central axis of the adjustment rod 21 is parallel to the central axis of the inner cavity of the guide frame 18. Therefore, it is convenient to adjust the relative position of the corresponding adjustment plate 17 by using the adjustment rod 21 .
[0021] Each of the adjusting rods 21 is provided with a scale layer 23, and the extension direction of the scale layer 23 is parallel to the central axis of the inner cavity of the guide frame 18. The scale layer 23 is provided to facilitate feedback of the position of the corresponding adjusting rod 21, so as to facilitate adjustment of the relative position of the two adjusting rods 21 and then the relative position of the first driven shaft 5. Furthermore, each of the adjusting rods 21 between the guide frame 18 and the corresponding adjusting plate 17 is provided with a spring 24, and the spring 24 is located above the corresponding adjusting plate 17. In the process of adjusting the tension of the two first chains 6, it is necessary to adjust the relative position of the first driven shaft 5 so that the two first chains 6 can work within the preset tension range. Installing the spring 24 on the adjusting rod 21 facilitates the release of the corresponding elastic force so that the adjusting plate 17 obtains the force in the corresponding direction, thereby allowing the first driven shaft 5 to obtain a downward force.

[0022] The exhaust pipe 15 is connected to the feeding end of the bag filter 25, and the gas phase outlet end of the bag filter 25 is connected to the induced draft pipe 26, and the induced draft pipe 26 is provided with a fan 27 and a regulating valve 28. Thus, it is convenient to separate and transport light particles in the grains delivered to the delivery port 2 by using the air flow entering the housing 1 through the delivery port 2, and transport them to the bag filter 25 through the exhaust pipe 15 for separation, so as to realize the dust caused by the grains being transported to the delivery port 2.
[0023] The feed port 3 is provided with a second hopper 29, and the second hopper 29 is provided with a screen 30, so as to facilitate filtering out large impurities contained in the grain; a level meter 35 is provided on the inner side of the shell 1, so as to facilitate feedback on whether the grain in the shell 1 has reached a preset warning level.
[0024] The use of this product is as follows: Figures 1 to 3 As shown, the grain to be transported is put into the second hopper 29. After being screened by the screen 30, large impurities remain above the screen 30 to form screened material, while the grain to be transported carries the light impurities into the inner cavity of the outer shell 1. When the level meter 35 feeds back a signal, the grain in the inner cavity of the outer shell 1 reaches the warning level, and at this time, the grain should be stopped from being transported into the second hopper 29.
[0025] When the food to be transported enters the inner cavity of the shell 1, the drive motor 32 and the fan 27 are turned on. The drive motor 32 drives the drive shaft 4 to rotate through the driven sprocket 31, the second drive sprocket 33 and the second chain 34. The drive shaft 4 drives the two first drive sprockets 7 and then drives the two first chains 6 to rotate, thereby driving the first hoppers 9 on the two first chains 6 to move synchronously, so that the first hopper 9 drives the food to be transported at the bottom of the inner cavity of the shell 1 to move upward. When the first hopper 9 moves to the first drive sprocket 7, the inclination of the first hopper 9 is It gradually becomes larger until the grain in the first hopper 9 freely falls onto the guide plate 12. In this process, after the fan 27 is started, it enters the inner cavity of the outer shell 1 from the discharge port 2 and blows directly to the grain in the falling state, thereby taking away the light particles in the grain, thereby realizing the separation of the light particles and the grain. The light particles are then transported to the exhaust pipe 15 and transported to the bag dust collector 25 for gas-solid separation; and the grain without light particles is transported to the discharge port 2 under the guidance of the guide plate 12, and thus transported to the downstream equipment outside the discharge port 2.
[0026] When the device runs to a preset cycle, the plug-in butterfly valve 14 should be opened to discharge the food and light particles temporarily stored at the bottom of the inner cavity of the shell 1, thereby reducing the light particles temporarily stored at the bottom.
[0027] Through this embodiment, by installing a discharge pipe 13 at the bottom of the shell 1 and installing a plug-in butterfly valve 14 on the discharge pipe 13, it is convenient to regularly discharge the light particulate matter temporarily stored at the bottom of the elevator because the first hopper 9 cannot act on it; by installing an exhaust pipe 15 on the top of the shell 1, and a bag-type dust collector 25 connected to the exhaust pipe 15, an induced draft pipe 26 connected to the gas phase outlet end of the bag-type dust collector 25, and a fan 27 installed on the induced draft pipe 26, it is possible to separate the light particulate matter carried in the grain transported out through the discharge port 2 by the air flow entering through the discharge port 2, thereby reducing the dust generated by the discharge port of the elevator.

Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
