Description

Technical Field

[0001] This utility model relates to the field of powder cleaning machines, and in particular to an air-separation type powder cleaning machine. Background Technology

[0002] An air-separation flour purifier is a device that uses airflow separation to remove impurities from flour. By adjusting the airflow and vibrating screen, it separates light impurities such as bran and wheat residue, improving flour purity. It features high efficiency, energy saving, and a high degree of automation, and is widely used in the flour processing industry. To ensure the accuracy of the purifier's screen movement trajectory and the uniformity of material distribution, the purifier's levelness must be strictly controlled during the installation and commissioning phase.

[0003] A patent application with application number CN201921854558.0 discloses a powder cleaning machine. This technical solution achieves support and shock absorption by installing shock-absorbing springs and buffer springs under the main body of the powder cleaning machine. However, due to the uneven weight distribution in different parts of the powder cleaning machine body, the shock-absorbing springs and buffer springs at different locations bear uneven loads, resulting in varying degrees of compression deformation. This uneven compression makes it difficult for the powder cleaning machine body to maintain a horizontal state, thus affecting the stability and working performance of the powder cleaning machine. Therefore, improvements are needed. Utility Model Content

[0004] The main purpose of this utility model is to provide an air-separated powder cleaner that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A wind-selective dust collector includes a dust collector body. A bottom support is symmetrically fixedly mounted on the lower end of the dust collector body. A multi-functional component is movably mounted on the bottom support. The multi-functional component consists of a support base plate, rubber pads, threaded rods, fixing nuts, shock-absorbing springs, drag-reducing components, internal threaded rings, and handles. The rubber pads are fixedly mounted on the lower end of the support base plate. Two threaded rods are symmetrically fixedly mounted on the upper end of the support base plate. Two fixing nuts are respectively mounted on the two threaded rods. Two shock-absorbing springs are respectively sleeved on the two threaded rods and located below the fixing nuts. Two drag-reducing components are movably sleeved on the two threaded rods and simultaneously fixedly mounted on the lower end of the shock-absorbing springs. Two internal threaded rings are respectively mounted on the two threaded rods and simultaneously located below the drag-reducing components. Several handles are respectively fixedly mounted on the outer walls of the two internal threaded rings. The drag-reducing component consists of a connecting base ring and contact rollers. Several contact rollers are rotatably mounted within the connecting base ring.

[0007] Preferably, two perforations are symmetrically formed on the lower side wall of the bottom bracket, and the perforations penetrate the lower side wall of the bottom bracket vertically.

[0008] Preferably, the threaded rod on the multifunctional component is movably inserted into a through hole opened on the lower side wall of the bottom bracket.

[0009] Preferably, the fixing nut on the multifunctional component is located inside the bottom bracket, and the shock-absorbing spring is located below the bottom bracket.

[0010] Preferably, the upper end of the internal threaded ring on the multifunctional component has an annular groove.

[0011] Preferably, the connecting base ring on the drag reduction assembly is movably sleeved on the threaded rod, and the connecting base ring is fixedly connected to the shock absorption spring. The lower end of the connecting base ring has a plurality of roller receiving grooves in an annular shape. The contact rollers are rotatably installed in the roller receiving grooves, and the contact rollers are simultaneously rotatably installed in the annular grooves.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By incorporating a multifunctional component consisting of a support base plate, rubber pads, threaded rods, fixing nuts, shock-absorbing springs, drag-reducing components, an internal threaded ring, and a handle, the vibration of the purifier body during operation can be effectively reduced, significantly decreasing wear and noise caused by vibration, thereby extending the equipment's service life and improving operational stability. Simultaneously, by rotating the internal threaded ring on the threaded rod using the handle, the compression degree of the shock-absorbing springs can be easily adjusted, flexibly adapting to the weight distribution differences in various parts of the purifier body. This adjustment method is not only simple to operate but also ensures the overall levelness of the purifier body, avoiding tilting problems caused by uneven loads, further optimizing the purifier body's working performance. The contact rollers and annular grooves in the drag-reducing component significantly reduce the frictional resistance between the internal threaded ring and the connecting base ring during adjustment, making the adjustment process smoother, reducing component wear, and improving adjustment accuracy and durability.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figure 1 - Figure 5As shown, a wind-selective dust collector includes a dust collector body 1. A bottom support 2 is symmetrically fixedly installed at the lower end of the dust collector body 1. A multi-functional component 3 is movably installed on the bottom support 2. The multi-functional component 3 consists of a support base plate 4, rubber pads 5, threaded rods 6, fixing nuts 7, shock-absorbing springs 8, drag-reducing components 9, internal threaded rings 10, and handles 11. The rubber pads 5 are fixedly installed at the lower end of the support base plate 4. There are two threaded rods 6 symmetrically fixedly installed at the upper end of the support base plate 4. There are two fixing nuts 7, each installed on one of the two threaded rods 6. There are two shock-absorbing springs 8... The damping spring 8 is located below the fixing nut 7 and is respectively fitted onto the two threaded rods 6. Two drag-reducing components 9 are movably fitted onto the two threaded rods 6 and are simultaneously fixedly installed at the lower end of the damping spring 8. Two internal threaded rings 10 are respectively installed on the two threaded rods 6 and are simultaneously located below the drag-reducing components 9. Several handles 11 are respectively fixedly installed on the outer walls of the two internal threaded rings 10. The drag-reducing component 9 consists of a connecting base ring 14 and contact rollers 13. Several contact rollers 13 are rotatably mounted on the connecting base ring 14. Inside, two symmetrical through holes 16 are opened on the lower side wall of the bottom support 2. The through holes 16 pass through the lower side wall of the bottom support 2 vertically. During use and installation, the threaded rod 6 of the multi-functional component 3 is inserted into the through hole 16 of the bottom support 2 to ensure that the support base plate 4 is in stable contact with the ground through the rubber pad 5. During initial installation, the fixing nut 7 is located inside the bottom support 2 to limit the initial position of the threaded rod 6. At this time, the shock-absorbing spring 8 is in a natural state or a slightly pre-compressed state, leaving room for subsequent fine adjustment. The method for adjusting the level of the powder cleaning machine body 1 is to turn the handle 11. Rotate the internal threaded ring 10 to move it up and down along the threaded rod 6. During this process, the contact roller 13 of the drag reduction component 9 will roll along the annular groove 12 and rotate within the roller receiving groove 15. When the internal threaded ring 10 rises, it will compress the shock-absorbing spring 8; conversely, when the internal threaded ring 10 falls, it will reduce the spring pressure. During this process, the rolling design of the contact roller 13 significantly reduces frictional resistance, making adjustment easier and more precise. After adjustment, the elastic deformation of the shock-absorbing spring 8 will absorb the vibration energy of the cleaning machine during operation, while the rubber pad 5 further weakens the impact transmitted from the ground.

[0022] Specifically, the threaded rod 6 on the multi-functional component 3 is movably inserted into the through hole 16 opened on the lower side wall of the bottom bracket 2. The fixing nut 7 on the multi-functional component 3 is located inside the bottom bracket 2. The shock-absorbing spring 8 is located below the bottom bracket 2. The upper end of the internal threaded ring 10 on the multi-functional component 3 is provided with an annular groove 12. Since the weight distribution of each part of the purifier body 1 is uneven, the compression of the shock-absorbing spring 8 can be controlled differently by independently adjusting the height of the internal threaded ring 10 corresponding to each bottom bracket 2. For example, the shock-absorbing spring 8 on the heavier side needs a larger compression force to balance the load, thereby ensuring that the purifier body 1 is level as a whole. This dynamic adaptation mechanism effectively avoids the equipment tilting problem caused by uneven load of traditional fixed springs.

[0023] Specifically, the connecting base ring 14 on the drag reduction assembly 9 is movably sleeved on the threaded rod 6, and the connecting base ring 14 is fixedly connected to the shock absorption spring 8. The lower end of the connecting base ring 14 has several roller receiving grooves 15 in an annular shape. The contact rollers 13 are rotatably installed in the roller receiving grooves 15, and the contact rollers 13 are simultaneously rotatably installed in the annular groove 12. The drag reduction assembly 9 maintains the flexibility of the adjustment structure during long-term use, avoids thread jamming or component wear caused by friction, and extends the service life of the equipment.

[0024] Finally, by setting up a multifunctional component 3 consisting of a support base plate 4, rubber pad 5, threaded rod 6, fixing nut 7, shock-absorbing spring 8, drag-reducing component 9, internal threaded ring 10, and handle 11, the vibration of the purifier body 1 during operation can be effectively reduced, significantly reducing wear and noise caused by vibration, thereby extending the service life of the equipment and improving its working stability. At the same time, by rotating the internal threaded ring 10 on the threaded rod 6 through the handle 11, the compression degree of the shock-absorbing spring 8 can be easily adjusted, flexibly adapting to the weight distribution differences of various parts of the purifier body 1. This adjustment method is not only simple to operate, but also ensures the overall levelness of the purifier body 1, avoiding tilting problems caused by uneven load, and further optimizing the working performance of the purifier body 1. The contact roller 13 in the drag-reducing component 9 cooperates with the annular groove 12, which can greatly reduce the frictional resistance between the internal threaded ring 10 and the connecting base ring 14 during the adjustment process, making the adjustment process smoother, while reducing component wear and improving adjustment accuracy and durability.

[0025] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
