Description

Technical Field

[0001] This solution belongs to the field of material feeding structure, specifically involving a bottom feeding structure for a dry powder silo. Background Technology

[0002] In industries such as chemicals, building materials, and food, the storage and feeding of dry powder materials are key aspects of the production process.

[0003] A search revealed that the invention patent application with publication number CN105329567A discloses a dry powder storage bin, which relates to the field of powder storage technology. The bin includes a support frame, a cylinder, a cone, a flexible connecting cylinder, a support spring, a vibration motor, a heat-conducting column, crushing teeth, and a material distribution component. The cylinder is arranged vertically, and its outer wall is connected to the support frame. The cone has a wide opening at the top and a narrow opening at the bottom, with the narrow opening serving as the discharge port and equipped with a discharge valve.

[0004] However, dry powder materials are prone to moisture absorption, clumping, hardening, or adhesion to the silo walls during storage and transportation, leading to poor material flow or even blockage, which affects production efficiency. Utility Model Content

[0005] The purpose of this solution is to provide a bottom-feeding structure for dry powder silos to solve the problem that dry powder materials are prone to moisture absorption, clumping, hardening, or adhesion to the silo walls during storage and transportation, leading to poor material flow or even blockage, which affects production efficiency.

[0006] To achieve the above objectives, this solution provides a dry powder silo bottom discharge structure, including a dry powder storage bin. A discharge pipe is connected to the bottom of the dry powder storage bin. Multiple supports are fixedly connected to the top of the dry powder storage bin. A support base is fixedly connected to all the supports. A motor is fixedly installed at the upper end of the support base. The output shaft of the motor passes through the support base and is connected to the support base via a bearing. A rotating shaft is fixedly connected to the end of the output shaft. A bushing is slidably sleeved on the outer side of the rotating shaft. A dispersing rod is fixedly connected to the outside of the bushing. An L-shaped rod is fixedly connected to the upper outer side of the bushing. An inclined seat is fixedly connected to the bottom of the support base. The end of the L-shaped rod abuts against the inclined surface of the inclined seat.

[0007] The principle of this solution is as follows: During use, the dry powder can be stored normally in the dry powder storage bin. When it is necessary to discharge the material, simply open the valve at the discharge pipe. At the same time, the motor drives the rotating shaft to rotate the dispersing rod, which can effectively break up the dry powder clumps. Meanwhile, by utilizing the cooperation between the L-shaped rod and the inclined surface of the inclined seat, the bushing vibrates axially periodically, which in turn drives the dispersing rod to vibrate up and down, further improving the efficiency of breaking up dry powder clumps. Moreover, while the bushing rotates, it also drives the scraper to rotate. Then, combined with the periodic collision between the scraper and the protrusion, the bin wall vibrates. This not only prevents the material from accumulating and clogging the discharge pipe, but also prevents the dry powder from adhering through bin wall vibration.

[0008] The technical advantages of this solution are as follows: by driving the rotating shaft with an electric motor to rotate the dispersing rod, the dry powder clumps can be effectively broken up. At the same time, by utilizing the cooperation between the L-shaped rod and the inclined surface of the inclined seat, the bushing vibrates periodically in the axial direction, which in turn drives the dispersing rod to vibrate up and down, further improving the efficiency of breaking up dry powder clumps.

[0009] By setting a combination of hollow sleeve, slide bar, scraper and spring two on the bushing, the scraper will abut against the inner wall of the dry powder storage bin under the elastic force of spring two. At the same time, protrusions are set on the inner wall of the dry powder storage bin. The periodic collision between the scraper and the protrusions causes the bin wall to vibrate. This not only prevents material from accumulating and clogging the feed pipe, but also prevents dry powder from adhering through bin wall vibration.

[0010] Furthermore, a guide rod is fixedly connected to the bottom inner side of the bushing. The guide rod is slidably connected to the rotating shaft, and a spring is sleeved on the outer side of the guide rod. The guide rod allows the rotating shaft to drive the bushing to rotate, while the bushing can simultaneously move up and down axially along the rotating shaft.

[0011] Furthermore, one end of the spring is fixedly connected to the rotating shaft, and the other end of the spring is fixedly connected to the inner bottom of the bushing. The spring provides auxiliary resetting for the axial movement of the bushing along the rotating shaft.

[0012] Furthermore, the rotating shaft is internally equipped with ball bearings, which are slidably connected to the guide rod. The ball bearings reduce the relative friction between the guide rod and the rotating shaft.

[0013] Furthermore, a hollow sleeve is fixedly connected to the outer side of the bushing, and a sliding rod is slidably connected inside the hollow sleeve. A scraper is fixedly connected to the end of the sliding rod, and the scraper abuts against the inner wall of the dry powder storage bin. A protrusion is fixedly connected to the inner wall of the dry powder storage bin, and the position of the protrusion corresponds to the position of the scraper. Through the periodic collision between the scraper and the protrusion, the bin wall of the dry powder storage bin can be vibrated, which can prevent material from adhering to the inner wall and also prevent blockage during material discharge.

[0014] Furthermore, a second spring is installed inside the hollow sleeve. One end of the second spring is fixedly connected to the slide rod, and the other end of the second spring is fixedly connected to the inner surface of the hollow sleeve. The second spring allows the elastic force to be applied to the scraper bar through the slide rod, ensuring that the scraper bar remains in contact with the inner wall of the dry powder storage compartment.

[0015] Furthermore, a support frame is fixedly connected to the outside of the dry powder storage compartment, and support legs are welded to the four corners of the bottom of the support frame. The support frame and support legs provide support for the entire structure. Attached Figure Description

[0019] The basic implementation examples are as follows: Figures 1-3 The diagram shows a dry powder storage silo bottom-feeding structure, including a dry powder storage silo 1. A discharge pipe 101 is connected to the bottom of the dry powder storage silo 1. Multiple supports 2 are fixedly connected to the top of the dry powder storage silo 1. A support base 3 is fixedly connected to the supports 2. A motor 4 is fixedly installed at the upper end of the support base 3. The output shaft of the motor 4 passes through the support base 3 and is connected to the support base 3 via a bearing. A rotating shaft 5 is fixedly connected to the end of the output shaft. A bushing 6 is slidably sleeved on the outer side of the rotating shaft 5. A dispersing rod 7 is fixedly connected to the outside of the bushing 6. An L-shaped rod 8 is fixedly connected to the upper outer side of the bushing 6. An inclined seat 9 is fixedly connected to the bottom of the support base 3. The end of the L-shaped rod 8 abuts against the inclined surface of the inclined seat 9. A support frame 18 is fixedly connected to the outside of the dry powder storage silo 1. Support legs 19 are welded to the four corners of the bottom of the support frame 18. The support frame 18 and support legs 19 provide overall support.

[0020] like Figure 3 , Figure 4 As shown, a guide rod 10 is fixedly connected to the inner bottom of the bushing 6. The guide rod 10 is slidably connected to the rotating shaft 5, and a spring 11 is sleeved on the outer side of the guide rod 10. The guide rod 10 allows the rotating shaft 5 to drive the bushing 6 to rotate, while the bushing 6 can also move axially up and down along the rotating shaft 5. One end of the spring 11 is fixedly connected to the rotating shaft 5, and the other end is fixedly connected to the inner bottom of the bushing 6. The spring 11 assists in resetting the bushing 6 during axial movement along the rotating shaft 5. A ball bearing 12 is installed inside the rotating shaft 5, and the ball bearing 12 is slidably connected to the guide rod 10. The ball bearing 12 reduces the relative friction between the guide rod 10 and the rotating shaft 5.

[0021] like Figure 3 As shown, a hollow sleeve 13 is fixedly connected to the outer side of the bushing 6. A sliding rod 14 is slidably connected inside the hollow sleeve 13. A scraper 15 is fixedly connected to the end of the sliding rod 14. The scraper 15 abuts against the inner wall of the dry powder storage bin 1. A protrusion 17 is fixedly connected to the inner wall of the dry powder storage bin 1, and the position of the protrusion 17 corresponds to the position of the scraper 15. Through the periodic collision between the scraper 15 and the protrusion 17, the bin wall of the dry powder storage bin 1 can vibrate, preventing material from adhering to the inner wall and preventing blockage during material discharge. A second spring 16 is installed inside the hollow sleeve 13. One end of the second spring 16 is fixedly connected to the sliding rod 14, and the other end of the second spring 16 is fixedly connected to the inner surface of the hollow sleeve 13. Through the setting of the second spring 16, the elastic force can be applied to the scraper 15 through the sliding rod 14, so that the scraper 15 always keeps in contact with the inner wall of the dry powder storage bin 1.

[0022] The specific implementation process of this utility model is as follows: When in use, the dry powder can be stored normally in the dry powder storage bin 1. When it is necessary to discharge the material, the valve at the discharge pipe 101 can be opened. At the same time, the motor 4 drives the rotating shaft 5 to rotate the dispersing rod 7, which can effectively disperse the dry powder clumps. Meanwhile, the L-shaped rod 8 and the inclined surface of the inclined seat 9 cooperate to make the bushing 6 periodically vibrate axially, which in turn drives the dispersing rod 7 to vibrate up and down, further improving the efficiency of dispersing the dry powder clumps. Moreover, when the bushing 6 rotates, it will drive the scraper 15 to rotate. Then, combined with the periodic collision between the scraper 15 and the protrusion 17, the bin wall will vibrate. This not only prevents the material from accumulating and blocking the discharge pipe 101, but also prevents the dry powder from adhering through the vibration of the bin wall.

[0023] This solution uses an electric motor 4 to drive a rotating shaft 5 to rotate a dispersing rod 7, which can effectively break up dry powder clumps. At the same time, by utilizing the cooperation between the L-shaped rod 8 and the inclined surface of the inclined seat 9, the bushing 6 vibrates axially periodically, which in turn drives the dispersing rod 7 to vibrate up and down, further improving the efficiency of breaking up dry powder clumps.

[0024] By setting a combination of hollow sleeve 13, slide bar 14, scraper 15 and spring 16 on bushing 6, the scraper 15 will abut against the inner wall of dry powder storage bin 1 under the elastic force of spring 16. At the same time, protrusions 17 are set on the inner wall of dry powder storage bin 1. The periodic collision between scraper 15 and protrusions 17 causes the bin wall to vibrate. This prevents material from accumulating and clogging the feed pipe 101, and also prevents dry powder from adhering through bin wall vibration.

[0025] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
