Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coal washing, in particular to a coal washing feeding and pushing device. Background Art
[0002] Coal washing generally refers to the process of removing gangue or other impurities from coal. Coal washing generally utilizes the different physical properties of coal and gangue to separate the coal and gangue (impurities) in media of different densities or characteristics. The treatment method is a completely closed-loop cycle and is divided into three levels of standards: Level 1, in which all coal slime is recovered by dewatering machinery within the plant, and all wash water is reused; Level 2, in which most of the coal slime is recovered within the plant, with a small portion recovered in an off-site sedimentation tank, and all wash water is reused; Level 3, in which the coal slime is settled in an off-site sedimentation tank, with most of the clean water reused, and the remaining water meeting discharge standards.
[0003] In the existing coal washing process, the coal needs to be loaded to facilitate subsequent washing. However, most of the existing loading devices move downward under the weight of the coal itself, and some small and damp coal is easily stuck inside the device, which not only affects the normal discharge of the coal, but also gradually blocks the discharge port, affecting the normal loading of the device.
[0004] At the same time, coal is light in weight, and during the movement of coal, some smaller coal will float in the air. Most existing devices do not have the structure to block and collect this part of the coal, which will not only affect the surrounding environment, but also affect the health of the workers. Utility Model Content
[0005] The purpose of the utility model is to provide a coal washing, feeding and pushing device to solve the problems raised in the above background technology.

[0007] A mounting shell is connected to both sides of the feed hopper body, a servo motor is bolted to the top of the mounting shell, a threaded rod is fixedly connected to the output shaft of the servo motor, a sleeve is threadedly connected to the surface of the threaded rod, and a push shell is fixedly connected to one side of the sleeve;
[0008] An installation groove is opened at the bottom of the pusher shell, and blocking plates are rotatably connected on both sides of the inner cavity of the installation groove, and torsion springs are fixedly connected on both sides of the inner cavity of the blocking plate. Magnet strips are embedded on both sides of the top of the inner cavity of the installation groove, and positioning plates are fixedly connected on both sides of the bottom of the pusher shell.

[0021] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.
[0022] See also Figure 1-4As shown, a coal washing and feeding pushing device includes a hopper body 1. The opening at the top of the hopper body 1 is larger than the opening at the bottom. The hopper body 1 is used to temporarily store the coal, and then the coal is evenly discharged by cooperating with the lower opening at the bottom. Both sides of the surface of the hopper body 1 are fixedly connected with support frames 2. The support frames 2 can support the hopper body 1 so that the opening at the bottom of the hopper body 1 corresponds to the conveyor belt. Both sides of the hopper body 1 are connected with mounting shells 3. The top of the mounting shell 3 is bolted with a servo motor 4. The output shaft of the servo motor 4 passes through the interior of the mounting shell 3 and is rotatably connected to the inner wall of the penetration. The output shaft of the servo motor 4 is fixedly connected with a threaded rod 5. The surface of the threaded rod 5 is threadedly connected The servo motor 4 can drive the sleeve 6 to move through the thread on the surface of the threaded rod 5, thereby providing power for the subsequent discharging. One end of the threaded rod 5 is fixedly connected to the bearing seat 15, and one side of the bearing seat 15 is fixedly connected to the inner wall of the mounting shell 3. Under this action, the threaded rod 5 can be limited when it rotates, so that the threaded rod 5 will not have a large position deviation when it rotates, effectively improving the stability of the threaded rod 5 during rotation, and avoiding the threaded rod 5 being unstable during rotation and affecting the threaded connection with the sleeve 6. The surface of the sleeve 6 is slidably connected to the inner wall of the mounting shell 3, and one side of the sleeve 6 is at the same horizontal line as the upper part of the inner wall of the feed hopper body 1. Under this action, the threaded rod 5 can be screwed on its surface When the sleeve 6 is driven to move under the action of the groove, the mounting shell 3 can guide the sleeve 6, so that the sleeve 6 can be more stable when moving, effectively improving the stability of the sleeve 6 when moving, and the top of the mounting shell 3 is fixedly connected with a protective shell 16, and the servo motor 4 is located inside the protective shell 16. Under this action, the servo motor 4 can be protected, so as to avoid damage caused by contact with the servo motor 4 when adding coal to the inside of the feed hopper body 1, effectively improving the service life of the servo motor 4, and a push shell 7 is fixedly connected to one side of the sleeve 6. The surface of the push shell 7 is slidably connected to the inner wall of the feed hopper body 1, and the inner cavity of the push shell 7 is designed as an inclined structure. The opening at the top of the push shell 7 is larger than the opening at the bottom. Under this action, the coal poured into the pushing shell 7 can be guided, so that the coal is conveniently discharged from the pushing shell 7. Guide rods 13 are fixedly connected to both sides of the inner cavity of the feeding hopper body 1, and guide grooves 14 are provided on both sides of the inner cavity of the pushing shell 7. The inner wall of the guide groove 14 is slidably connected to the surface of the guide rod 13, which can be used to guide the pushing shell 7 when it moves, so that the pushing shell 7 is more stable when it moves, avoiding the pushing shell 7 from being unstable when moving and affecting the pushing effect of the coal. A mounting groove 8 is provided at the bottom of the pushing shell 7, and blocking plates 9 are rotatably connected on both sides of the inner cavity of the mounting groove 8. Torsion springs 10 are fixedly connected on both sides of the inner cavity of the blocking plate 9, and the other end of the torsion spring 10 is fixedly connected to the inner wall of the mounting groove 8.The surface of the blocking plate 9 is movably connected to the inner wall of the mounting groove 8, under which the blocking plate 9 can block the opening at the bottom of the pushing shell 7, so that when the pushing shell 7 descends, the two blocking plates 9 can block the opening of the pushing shell 7, so that the pushing shell 7 and the blocking plate 9 cooperate with each other to push the coal inside the feeding hopper body 1 to the bottom of the feeding hopper body 1, which is convenient for the device to discharge materials. With the cooperation of the torsion spring 10, the blocking plate 9 can be rotated when it is subjected to a large weight, and when it is not squeezed, the torsion spring 10 can make the blocking plate 9 return to its original position, which can not only block foreign matter such as dust inside the feeding hopper body 1, but also facilitate the pushing of coal. Both sides of the top of the inner cavity of the mounting groove 8 are embedded with magnet strips 11. The material of the blocking plate 9 is iron. The magnet strips 11 are used in conjunction with the blocking plate 9. Under this action, the blocking plate 9 can be easily limited, so that the blocking plate 9 will not rotate slightly under the action of its own weight, effectively improving the limiting effect of the blocking plate 9. Both sides of the bottom of the pushing shell 7 are fixedly connected with a locking plate 12. The other end of the locking plate 12 penetrates the outside of the feeding hopper body 1 and is slidably connected to the inner wall of the penetration point. Under this action, the interior of the mounting shell 3 can be blocked, so that the coal inside the feeding hopper body 1 will not enter the interior of the mounting shell 3 and affect the threaded connection between the threaded rod 5 and the sleeve 6.
[0023] It is worth noting that the technical features such as the feeding hopper 1 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected according to conventional methods in the field, and this technical solution will not be further elaborated.
[0024] Working principle: First, the servo motor 4 and the threaded rod 5 cooperate to make the sleeve 6 drive the push shell 7 and the parts on its surface to move to the top of the inner cavity of the feed hopper body 1, and then the coal to be washed is poured into the inner cavity of the push shell 7. Under the cooperation of the shape of the push shell 7 and the baffle plate 9, the coal will squeeze the baffle plate 9 to make it rotate, and then the coal falls into the interior of the feed hopper body 1. After all the coal in the inner cavity of the push shell 7 enters the interior of the feed hopper body 1, the baffle plate 9 can return to its original position under the action of the torsion spring 10, thereby blocking the opening at the top of the feed hopper body 1 to prevent dust and foreign matter from floating in the air at will. When the coal needs to be pushed, the feed hopper body 1 is opened, and the coal is discharged from the bottom under the action of the feed hopper body 1. Then the servo motor 4 is turned on to drive the push shell 7 and the baffle plate 9 to squeeze the coal through the cooperation of the threaded rod 5 and the sleeve 6, so that the coal can be fed.
