Description

Technical Field

[0001] The utility model relates to the technical field of star-shaped dischargers, in particular to an anti-blocking star-shaped discharger. Background Art

[0002] A star discharger typically consists of a motor, a speed reducer, a star rotor (a rotor with several blades), a housing, and seals. The motor is the driving force behind the star discharger, while the speed reducer reduces the rotational speed and increases the torque, enabling smooth rotation of the star rotor. The star discharger operates by rotating the star rotor through an electric speed reducer motor, thereby conveying material. Material falls from the upper hopper, filling the spaces between the blades and being discharged as the blades rotate. As the material in the upper hopper falls by its own weight into the spaces between the blades, it is discharged from the lower portion as the blades rotate, achieving quantitative and continuous discharge.

[0003] A Chinese patent with announcement number CN213111554U discloses a star-shaped discharger with anti-sticking and blocking properties, including a star-shaped discharger body and a support block. A blowing port is provided on one side surface of the star-shaped discharger body, the cross-section of the support block is concave, a hair dryer is fixedly connected to the upper surface of the support block, the air outlet of the hair dryer is provided with an anti-sticking and blocking mechanism, and the anti-sticking and blocking mechanism includes an air supply pipe, and the air outlet of the hair dryer is fixedly connected to the inner wall of one side of the air supply pipe.

[0004] The aforementioned prior art solution suffers from the following drawbacks: A blower, through an air supply duct, blows air into the discharger body to prevent material from sticking and causing blockage during the discharge process. If the material is highly sticky or has high humidity, the blower's wind force may not be sufficient to completely prevent blockage. Once material forms a blockage within the discharger, the blower and air supply duct design do not provide an effective mechanism to automatically clear the blockage.

[0005] Therefore, we proposed an anti-blocking star-shaped discharger to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide an anti-blocking star-shaped discharger to solve the problem in the above-mentioned background technology that blocked materials cannot be processed.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an anti-blocking star-shaped discharger, comprising an upper flange, a shell, a seal, a feed pipe and a discharge pipe, wherein the upper flange is fixedly connected to the upper part of the shell, the seal is fixedly connected to the right side of the shell, the feed pipe is fixedly connected to the lower part of the shell, the bottom of the feed pipe is fixedly connected to the lower flange, the top of the discharge pipe is fixedly connected to the lower flange, the left side of the shell is fixedly connected to a motor 1, the output end of the motor 1 is connected to a rotating shaft, the rotating shaft is fixedly connected to an impeller, and an anti-blocking mechanism is provided inside the shell;

[0008] The anti-blocking mechanism includes a discharge unit and a unloading unit;

[0009] The discharge unit includes an anti-blocking tube, a groove, a spring 1, a limiting rod, an anti-blocking door and a connecting block. The middle part of the anti-blocking tube is fixedly connected to the outside of the discharge tube, and the groove is opened on both sides of the inside of the anti-blocking tube. The limiting rod is fixedly connected to the inside of the groove and extends outward. The spring 1 is connected to the outside of the limiting rod, one end of the spring 1 is fixedly connected to the groove, and the other end of the spring 1 is fixedly connected to the connecting block. The connecting block is slidably connected to the limiting rod and the inner side is fixedly connected to the anti-blocking door, and the anti-blocking door is embedded in the anti-blocking tube.

[0010] Preferably, the diameter of the lower opening of the discharge pipe is larger than the diameter of the upper opening of the discharge pipe, which helps the material to be discharged from the discharge pipe more smoothly and reduces the risk of blockage. Since the lower opening diameter is larger, the resistance encountered by the material during discharge is smaller, thereby improving the efficiency of discharge.

[0011] Preferably, the unloading unit includes a transfer bar, a blanking plate, a fixed plate, a second motor, a cam, a connecting rod, and a second spring. The two ends of the transfer bar are rotatably connected to the upper part of the discharge pipe, the blanking plate is fixedly connected to the transfer bar, the fixed plate is fixedly connected to the lower part of the blanking plate in a semi-arc shape, the second motor is fixedly connected to the upper surface of the fixed plate, one side of the cam is connected to the output end of the second motor, the bottom of the connecting rod is connected to the fixed plate, the top of the connecting rod is connected to the blanking plate, and the second spring is connected to the outside of the connecting rod. The cam is driven to rotate by the second motor, thereby driving the blanking plate to perform periodic up and down movement. This movement method helps to distribute the material more evenly in the discharge pipe and promotes the smooth discharge of the material, further reducing the possibility of blockage.

[0012] Preferably, the discharge plate is arranged at a certain angle inside the discharge pipe, which can make the material slide down along the discharge plate more easily under the action of gravity, thereby improving the efficiency of unloading. At the same time, this design also helps to reduce the accumulation of materials in the discharge pipe and reduce the risk of blockage.

[0013] Preferably, there are two groups of connecting rods and springs, which are respectively arranged at the two ends between the blanking plate and the fixed plate, so as to control the movement of the blanking plate more stably.

[0014] Preferably, the raised side of the cam contacts the blanking plate, which can more effectively drive the blanking plate to move up and down. This contact method can ensure that the cam can fully transmit power to the blanking plate when rotating, thereby improving the unloading efficiency of the unloader.

[0015] Preferably, a connecting shaft is rotatably connected to the bottom of the fixed plate, and both ends of the connecting shaft are rotatably connected to the bottom of the discharge pipe. Blades are fixedly connected to the connecting shaft, and the blades are cross-distributed, which can further promote the flow of materials in the discharge pipe. The cross distribution of the blades can ensure that the material can be evenly stirred and pushed in all directions, thereby reducing the risk of material accumulation and blockage in the discharge pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The anti-blocking star-shaped discharger has an anti-blocking pipe, spring, limit rod, anti-blocking door and other components in the discharge unit that work together. When the discharge pipe is blocked, the material inside will push the anti-blocking door open. When it is not blocked, the anti-blocking door returns to its original position driven by the spring and connecting block, which can effectively prevent material accumulation in the pipeline.

[0018] 2. The anti-blocking star-shaped discharger has a periodic up and down motion mechanism composed of motor 2, cam, connecting rod, spring 2 and blanking plate in the discharge unit, which can further promote the uniform distribution and smooth discharge of materials. The connecting rod and spring 2 can also ensure that the blanking plate will not produce excessive shaking or deviation during the up and down movement, thereby ensuring the continuity and uniformity of unloading.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1-4 , the utility model provides a technical solution: Example

[0026] A star-shaped discharger with anti-clogging function includes an upper flange 1, a shell 2, a seal 3, a discharge pipe 4 and a discharge pipe 5. The upper flange 1 is fixedly connected to the top of the shell 2. The upper flange 1 ensures that the shell 2 can be stably fixed in the desired position and provides a connection interface for the pipeline. The shell 2 is the main structure of the discharger, which is used to accommodate internal components such as the motor, impeller and anti-clogging mechanism. It provides the necessary protection and support to ensure that the discharger can work properly. The seal 3 is fixedly connected to the right side of the shell 2. The seal 3 ensures that the material inside the shell 2 will not leak into the external environment, and prevents external impurities from entering the inside of the discharger, thereby ensuring the sealing and reliability of the discharger. The discharge pipe 4 is fixedly connected to the bottom of the shell 2. The discharge pipe 4 is the channel for the material to flow from the shell 2 to the discharge pipe 5. Its design ensures that the material can flow out smoothly and reduces the risk of blockage. The bottom of the discharge pipe 4 is fixedly connected to a lower flange, and the top of the discharge pipe 5 is fixedly connected to a lower flange. The diameter of the pipe opening below the discharge pipe 5 is larger than the diameter of the pipe opening above the discharge pipe 5. The design of the pipe opening below the discharge pipe 5 being larger than the diameter above helps to discharge the material more smoothly, reduces the risk of blockage, and improves the unloading efficiency. A motor 6 is fixedly connected to the left side of the shell 2, and the output end of the motor 6 is connected to the rotating shaft 601. The motor 6 provides power for the discharger, driving the rotating shaft 601 and the impeller 602 to rotate, thereby realizing the transportation of materials. An impeller 602 is fixedly connected to the rotating shaft 601, and the rotating shaft 601 connects the motor 6 and the impeller 602, transmitting the power of the motor 6 to the impeller, so that the impeller can rotate and push the material forward. An anti-blocking mechanism is provided inside the shell 2;

[0027] The anti-blocking mechanism includes a discharge unit;

[0028] The discharge unit comprises an anti-blocking tube 7, a groove 701, a spring 1 702, a stopper 703, an anti-blocking door 704, and a connecting block 705. The middle portion of the anti-blocking tube 7 is fixedly connected to the outside of the discharge tube 4. Grooves 701 are provided on either side of the anti-blocking tube 7, providing mounting locations for the stopper 703. The design of the grooves 701 ensures that the stopper 703 is stably fixed within the anti-blocking tube 7, providing reliable support for the spring 1 702 and the connecting block 705. The stopper 703 is fixedly connected to the groove 701 and extends outward. It guides and restricts the movement of the connecting block 705. The stopper 703 ensures that the connecting block 705 can only move in a specific direction under the action of the spring 1 702, thereby ensuring the stability and reliability of the anti-blocking door 704. Spring 1 702 is connected to the outside of limit rod 703. One end of spring 1 702 is fixedly connected to groove 701, and the other end is fixedly connected to connecting block 705. When material flow is smooth, spring 1 702 maintains a certain tension, keeping anti-blocking door 704 closed. When material flow is blocked, the outward force generated by the material against anti-blocking door 704 pulls spring 1 702, pushing anti-blocking door 704 outward, allowing material to flow out. Connecting block 705 is slidably connected to limit rod 703 and fixedly connected to anti-blocking door 704 on its inner side. Anti-blocking door 704 is embedded in anti-blocking tube 7 and is used to control the outflow of material. Example

[0029] Based on the first embodiment, the anti-blocking mechanism further includes a discharge unit; the discharge unit comprises a transfer bar 901, a discharge plate 902, a fixed plate 903, a second motor 904, a cam 905, a connecting rod 906, and a second spring 907. The ends of the transfer bar 901 are rotatably connected to the upper interior of the discharge pipe 5. The discharge plate 902 is fixedly connected to the transfer bar 901 and positioned at a certain angle within the discharge pipe 5. The fixed plate 903 is fixedly connected to the bottom of the discharge plate 902 in a semi-arc shape. The second motor 904 is fixedly connected to the upper surface of the fixed plate 903. One side of the cam 905 is connected to the output end of the second motor 904, and the raised side of the cam 905 contacts the discharge plate 902. The bottom of the connecting rod 906 is connected to the fixed plate 903, and the top of the connecting rod 906 is connected to the discharge plate 902. The second spring 907 is connected to the outer side of the connecting rod 906. There are two sets of connecting rods 906 and springs 907, respectively, located at both ends between the discharge plate 902 and the fixed plate 903. The discharge unit drives the cam 905 to rotate via motor 904, which in turn drives the discharge plate 902 to perform periodic up and down motions, helping to more evenly distribute the material within the discharge pipe and promote smooth discharge of the material. A connecting shaft 801 is rotatably connected below the fixed plate 903. The two ends of the connecting shaft 801 are rotatably connected to the lower interior of the discharge pipe 5. Blades 802 are fixedly connected to the connecting shaft 801, and the blades 802 are arranged in a cross shape. The design of the connecting shaft 801 and blades 802 further promotes the flow of material within the discharge pipe, reducing the risk of material accumulation and blockage in the discharge pipe 5.

[0030] Working Principle: When material flows from housing 2 into discharge pipe 4, it first encounters anti-blocking pipe 7. Spring 1 702 maintains a closed position within anti-blocking pipe 7, preventing material from accumulating within the pipe. When material flow is smooth, spring 1 702 maintains tension, keeping anti-blocking pipe 704 closed and preventing leakage. When material flow is obstructed, such as when encountering large or viscous materials, the material pushes against anti-blocking pipe 704, generating an outward force that stretches spring 1 702. This forces anti-blocking pipe 704 outward, allowing material to flow out and preventing blockage.

[0031] The material then passes through discharge pipe 5. Motor 2 904 drives cam 905 to rotate, which in turn drives blanking plate 902 in a periodic up and down motion. The up and down motion of blanking plate 902 helps distribute the material more evenly within discharge pipe 5 and facilitates smooth discharge. Furthermore, the design of connecting shaft 801 and blade 802 further facilitates the flow of material within discharge pipe 5, reducing the risk of material accumulation and blockage.

[0032] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device.
