Description

Technical Field

[0001] The utility model relates to the technical field of related equipment of a silo, in particular to a blanking assembly applied to a silo. Background Art

[0002] In many industrial production processes, as a common device for storing and temporarily storing bulk materials, a silo plays a crucial role in the storage and continuous feeding of materials. The silo needs to effectively transport the materials from the storage space to the downstream processing or packaging equipment to ensure the smooth operation of the production line. However, in the existing silo discharging technologies, there are a series of efficiency and reliability problems, which significantly restrict the production efficiency.

[0003] First of all, currently, silos generally lack special blanking equipment, and mostly use simple opening release or primitive methods relying on gravity and external force assistance to discharge materials. This method may be able to meet the basic production needs under the conditions of good material fluidity and without the need for moisture-proof and anti-caking. However, when facing materials with strong hygroscopicity or easy caking, this simple discharging method will expose many deficiencies.

[0004] Secondly, due to the influence of various factors, such as changes in climate humidity, inherent properties of materials, and extension of storage time, the materials at the bottom of the silo are prone to form lumps. These lumpy materials will not only reduce the discharging efficiency of the blanking port, but also may cause blockage of the blanking port. In severe cases, manual intervention is required, which not only increases the labor intensity, but also reduces the automation level and increases the uncertainty and risk of production.

[0005] Furthermore, when the materials stay in the silo for a long time or experience changes in temperature and humidity in the silo, the adhesiveness between the materials increases, further aggravating the caking phenomenon and resulting in low discharging efficiency of the silo. In some cases, employees have to regularly check the silo and take measures to physically break up the lumps. This method is time-consuming and laborious, and cannot guarantee the needs of continuous production. Content of the Utility Model

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figure 1-7 , a blanking component applied to a silo, assembled at the blanking port 1 at the bottom of the silo, including a fitting sleeve 2 fixedly installed at the bottom of the blanking port 1 and a rotating sleeve 3 rotatably installed in the outer sleeve. An assembly cavity 21 and a discharging cavity 22 are arranged in the fitting sleeve 2 from top to bottom. The rotating sleeve 3 includes a communicating part 31 and a blanking part 32 that are fixedly connected. The communicating part 31 is rotatably installed in the assembly cavity 21, and the blanking part 32 is in communication with the communicating part 31 and is arranged in the discharging cavity 22. Discharging ports 321 communicating with the discharging cavity 22 are evenly arranged on the side wall of the blanking part 32.

[0029] It further includes a guiding sleeve 4 assembled inside the blanking port 1 and a material blocking sleeve 5 rotatably installed in the guiding sleeve 4. The guiding sleeve 4 is fixedly connected in communication with the communicating part 31, and a helical guiding passage 41 is arranged on the side wall of the guiding sleeve. The guiding passage 41 is in communication with the inner cavity of the guiding sleeve 4. The side wall of the material blocking sleeve 5 is in contact with the inner port of the guiding passage 41, and a guiding through port 51 is arranged on the side wall of the material blocking sleeve 5;

[0030] It further includes a driving component power-connected to the rotating sleeve 3 and a posture adjustment component power-connected to the material blocking sleeve 5.

[0031] The material discharge assembly provided in the present application is used to control the material stored in the material tower to be discharged outwardly. The assembly sleeve 2 is installed on the outside of the material discharge port 1 to ensure that the rotating sleeve 3 and the material guiding sleeve 4 fixed as a whole are stably installed therein, wherein the setting of the assembly cavity 21 can ensure that the rotating sleeve 3 rotates stably therein, and at the same time, the unloading cavity 22 at the bottom thereof can receive the material discharged from the material guiding sleeve 4 and the rotating sleeve 3 and arrange it to the outside of the assembly sleeve 2.

[0032] The bottom surface of the material guiding sleeve 4 is kept in contact with the bottom of the material tower to prevent the material from being deposited at the bottom of the material guiding sleeve 4 and affecting its normal discharge. When the driving assembly drives the rotating sleeve 3 and the material guiding sleeve 4 to operate, ensure that the outer port of the material guiding passage 41 is tangential to the material at the bottom of the material tower, so that the material enters the inner cavity of the material guiding sleeve 4 through the material guiding passage 41, and then passes through the connecting part 31 and the unloading part 32 of the rotating sleeve 3, and finally falls into the discharge cavity 22 of the assembly sleeve 2 from the discharge port 321, and is finally discharged outward from the discharge cavity 22.

[0033] When the posture adjustment component drives the material blocking sleeve 5 to operate, when the side wall of the material blocking sleeve 5 fits with the inner port of the material guiding passage 41, the material guiding passage 41 can be blocked, thereby blocking the material discharge port 1 of the material tower to prevent the material therein from leaking down through the material guiding passage 41; when the material guiding port 51 of the material blocking sleeve 5 is opposite to the inner port of the material guiding passage 41, the material in the material tower can enter the rotating sleeve 3 through the material guiding passage 41 and the material guiding port 51, so that the material in the material tower can be discharged outward.

[0034] In order to prevent the bottom wall of the material-blocking sleeve 5 from blocking the connecting portion 31 of the rotating sleeve 3 , a material-guiding notch 52 is provided at the bottom of the material-blocking sleeve 5 to ensure that the material can fall into the rotating sleeve 3 below through the material-guiding notch 52 .

[0035] In order to ensure that the material outputted from the unloading portion 32 of the rotating sleeve 3 can be effectively discharged from the unloading cavity 22 of the assembly sleeve 2, the following technical solution is provided.

[0036] The discharge cavity 22 is configured as a wide-mouth structure, and a discharge through hole 221 is formed on a side wall of the discharge cavity 22 .

[0037] The discharge cavity 22 is configured as a wide-mouth structure to prevent the gap between the discharge cavity 22 of the assembly sleeve 2 and the lower material portion 32 of the rotating sleeve 3 from being too narrow, thereby affecting the normal discharge of materials. The configuration of the discharge through hole 221 can ensure that the materials falling into the discharge cavity 22 are effectively discharged from the discharge through hole 221.

[0038] In order to ensure that the driving assembly can be stably installed and effectively drive the rotating sleeve 3 and the material guiding sleeve 4 to operate stably, the following technical solution is provided.

[0039] An outer wall of the assembly cavity 21 is fixedly connected with an assembly housing 211. The driving assembly includes a first motor 61, a driving bevel gear 62, and a transmission bevel gear 63. The first motor 61 is fixedly installed in the assembly housing 211. The driving bevel gear 62 is fixedly connected to an output shaft of the first motor 61 and is arranged in the assembly cavity 21. The transmission bevel gear 63 is fixedly connected to the periphery of the communication part 31 and meshes with the driving bevel gear 62.

[0040] The arrangement of the assembly housing 211 can ensure the stable installation of the first motor 61. At the same time, it can cover the first motor 61 to prevent it from being eroded by the dust generated during the discharging process. When the first motor 61 drives the driving bevel gear 62 to operate, it can drive the rotating sleeve 3 and the material guiding sleeve 4 to operate stably, so that the outer end face of the material guiding path 41 of the material guiding sleeve 4 tangentially contacts the material in the material tower, and the material can be accelerated into the material guiding sleeve 4 to improve the discharging speed of the material tower.

[0041] To ensure the stable installation of the posture adjustment assembly and effectively drive the baffle sleeve 5 to rotate to realize the opening and closing adjustment of the material guiding path 41, the following technical solutions are provided.

[0042] The rotating sleeve 3 further includes a mounting part 33 fixedly connected below the material discharging part 32. The mounting part 33 is separated from the material discharging part 32. The posture adjustment assembly includes a mounting shaft 71, a second motor 72, and a matching combination of a worm gear 73 and a worm 74. The mounting shaft 71 is rotatably installed in the rotating sleeve 3 and is fixedly connected to the baffle sleeve 5. The worm gear 73 is fixedly connected to the bottom of the mounting shaft 71 and is arranged in the inner cavity of the mounting part 33. The worm 74 is rotatably installed in the mounting part 33 and is power-connected to the second motor 72. The second motor 72 is fixedly installed in the mounting part 33.

[0043] The arrangement of the mounting part 33 can ensure the stable installation of the posture adjustment assembly therein. When the driving assembly drives the rotating sleeve 3 to operate, the posture adjustment assembly operates synchronously with the rotating sleeve 3. The mounting part 33 is also arranged in the discharging cavity 22. A first bevel gear 741 is fixedly connected to the end of the worm 74, and a second bevel gear 721 that meshes with the first bevel gear 741 is fixedly connected to the output shaft of the second motor 72.

[0044] When the second motor 72 drives the second bevel gear 721 to operate, it further drives the worm 74 to operate. The worm 74 can drive the worm gear 73 and the mounting shaft 71 and the baffle sleeve 5 fixedly connected thereto to operate. The baffle sleeve 5 controls the opening and closing posture of the material guiding path 41.

[0045] The combination of the worm gear 73 and the worm 74 also has a self-locking effect, that is, the power at the end of the worm gear 73 cannot be transmitted to the worm 74. Then, the worm 74 locks the worm gear 73 so that the baffle sleeve 5 always maintains a specific posture to ensure the stability of the material storage or external discharge of the material tower.

[0046] To prevent the materials in the silo from caking due to moisture absorption, which may affect the normal discharge of the materials, the following technical solutions are provided.

[0047] The top end of the mounting shaft 71 extends above the material guiding sleeve 4, and the bottom end of the mounting shaft 71 extends below the fitting sleeve 2. An air supply passage 711 is provided at the center of the mounting shaft 71. A nozzle 712 communicating with the air supply passage 711 is fixedly connected to the top end of the mounting shaft 71. An air supply interface 713 sleeving the periphery of the mounting shaft 71 is fixedly connected to the bottom of the fitting sleeve 2.

[0048] The air supply interface 713 is connected to a pressurized gas tank or a pressurized pump, and is used to convey pulsed dry air to the air supply passage 711. The dry air is conveyed into the silo through the nozzle 712 to disperse the caked materials, further improving the discharging speed of the silo.
