Description

Technical Field

[0001] This invention relates to the field of starch production equipment technology, and in particular to a cyclone separator for starch production and its vibration damping structure. Background Technology

[0002] In starch production, starch granules need to be extracted, which typically involves using a cyclone separator. Cyclone separators are mainly used to separate starch and protein in starch production. Their main advantages are simple structure, high operational flexibility, high efficiency, convenient management and maintenance, and low cost. However, they generate considerable noise during production.

[0003] Most of the noise generated by cyclone separators is not high-decibel noise, but in most cases the low-frequency noise they produce can cause chronic damage to the human body, making people irritable and easily angered. Long-term exposure may also cause neurasthenia, insomnia and other neurological diseases.

[0004] The vibration and noise of cyclone separators mainly occur at 50Hz and its harmonics. This type of low-frequency noise is characterized by strong penetration and slow attenuation, and propagates primarily through air and structures. In many factories, cyclone separators are usually located on the ground floor. The vibration of the cyclone separator is directly transmitted to the walls through connecting bars, and then to the offices upstairs, causing noise problems.

[0005] To address the vibration and noise issues of cyclone separators, existing technologies employ various structural improvements. For instance, Chinese Patent CN208649178U discloses a cyclone separator for starch production, comprising a cylinder, an outer cylinder, and an inner cylinder, with a cavity between them. The inner wall of the outer cylinder has several first damping rings, and the outer wall of the inner cylinder has several second damping rings corresponding to the first damping rings. The opposing first and second damping rings abut against each other. Both the first and second damping rings have openings. One of two adjacent first damping rings is inserted into the opening of a second damping ring, and the opening of the other first damping ring is inserted into the corresponding second damping ring. A sound-insulating block is also provided between the inner wall of the outer cylinder and the outer wall of the inner cylinder, with several sound-insulating holes arranged in a honeycomb pattern.

[0006] The cyclone bee tool has a reasonable and simple structure, is highly practical, features a noise-reducing cylinder, and has strong pressure resistance.

[0007] However, this type of cyclone separator can only reduce the transmission of some vibrations, and a considerable amount of vibration is still transmitted to the wall through the elastic material. On the other hand, the materials used in the elastic connection may have a shorter lifespan under the influence of electric field and electromagnetic force, and are prone to failure. Summary of the Invention

[0008] To address the aforementioned technical problems and overcome the shortcomings of existing technologies, this invention provides a cyclone separator for starch production and its shock-absorbing structure.

[0009] Technical benefits: The structure of the mounting base has been improved. The mounting base is divided into several sections through a connecting mechanism, and the installation is carried out in sections during the loading process. This reduces the alignment steps required during the installation of the mounting base. At the same time, the installation weight of the mounting base is greatly reduced after dividing it into several sections, which greatly reduces the installation difficulty, increases the construction speed, and reduces the installation cost. In addition, dual vibration isolation technology is applied and damping particles are filled in, which greatly improves the vibration isolation performance of the vibration damping device and reduces noise generation.

[0010] The technical solution further defined in this invention is:

[0011] A shock-absorbing structure for a cyclone separator includes a separator body and a mounting base for connecting the mounting surface and the separator body, characterized in that: the mounting base includes a horizontal fixing seat and a vertical fixing seat that are installed in sections;

[0012] The mounting base is equipped with a dual vibration damping component, including

[0013] The first vibration damping component is fixed to the bottom of the separator body and is used to achieve the first vibration isolation of the separator body;

[0014] The second vibration damping component is located between the first vibration damping component and the mounting surface and is directly fixed to the mounting surface to achieve a second vibration isolation for the separator body.

[0015] The mounting frame is located between the first and second vibration dampers and is used to lock and fix the two together and transmit vibration to the second vibration damper.

[0016] Two horizontal and two vertical fixing seats are symmetrically arranged and connected end to end to form a square shape and locked together by the mounting frame. The mounting frame is fixed at both ends of the two horizontal fixing seats and is provided with a mounting part for locking and connecting with the vertical fixing seat.

[0017] The bottom of the separator body has a transverse frame and a longitudinal frame. The two ends of the transverse frame are fixed to the longitudinal fixing seats at the corresponding positions, and the two ends of the longitudinal frame are fixed to the transverse fixing seats at the corresponding positions.

[0018] Furthermore, the first damping element is a general-purpose vibration isolator mounted on a mounting base, or formed by filling the mounting base with damping particles.

[0019] In the aforementioned cyclone separator vibration damping structure, when the mounting base is filled with damping particles to form the first vibration damping element, both the transverse fixed seat and the longitudinal fixed seat are provided with several placement cavities for accommodating the filled damping particles; the type, particle size and filling rate of the damping particles filled in each placement cavity are the same or different or partially the same.

[0020] The aforementioned damping structure for a cyclone separator uses iron-based or ceramic particles as damping particles. The surface friction factor of these damping particles is 0.1–0.66, the surface restitution coefficient is 0.05–0.5, and the density is 0.5–10 g / cm³. 3 The filling rate is 70%–90%.

[0021] In the aforementioned vibration damping structure of a cyclone separator, when the first vibration damping component is a general-purpose vibration isolator, both the first and second vibration damping components are at least one of spring vibration isolators, rubber vibration isolators, air spring vibration isolators, wire rope vibration isolators, or spring-rubber composite vibration isolators.

[0022] The aforementioned shock-absorbing structure for a cyclone separator includes a mounting section comprising a groove formed on a mounting frame and a plate integrally formed at both ends of a longitudinal frame. One side of the groove is open, and the shape of the plate matches the shape of the groove.

[0023] The mounting frame has a support plate on one side of the slot opening. The support plate is bent at a right angle. The distance between the two opposing support plates is the same as the length of the longitudinal fixing seat, which is used to clamp and support the longitudinal fixing seat.

[0024] The aforementioned cyclone separator shock absorption structure has several bolts fixed in the groove, which are perpendicular to the horizontal plane, and several elongated holes corresponding to the bolts on the plate, which are used to lock the plate in the groove with the bolts.

[0025] A connecting crossbar is provided between the two transverse fixing seats. The connecting crossbar is located in the middle of the transverse fixing seats and is used to fasten the two transverse fixing seats together.

[0026] The vibration damping structure of the cyclone separator described above has at least four first damping blocks, which are respectively connected to the bottom of the separator body in the horizontal and vertical directions; and at least four second damping blocks.

[0027] The mounting frame has corresponding mounting slots for accommodating the second vibration damper. There are at least four mounting slots facing the ground, and each mounting slot is fitted with a second vibration damper.

[0028] The present invention also provides a cyclone separator for starch production, which has a shock-absorbing structure of any of the above-mentioned cyclone separators, and the separator body is connected to a wall via a connecting row, a mounting frame is fixed on the wall, the connecting row is fixed on the mounting frame, and the connecting row is connected to the separator body via several parallel connecting plates.

[0029] The aforementioned cyclone separator for starch production has a connecting plate made of elastic metal material. The connecting plate includes a vertical section fixed to the separator body, a horizontal section connected to the connecting bar, and a connecting section connecting the vertical section and the horizontal section. The vertical section, the horizontal section, and the connecting section are rounded at the corners.

[0030] The beneficial effects of this invention are:

[0031] (1) In this invention, ordinary cyclone separators are installed directly on a horizontal surface, which will cause great vibration to the floor and walls through the base and connecting strip, resulting in a lot of noise. This invention sets up a double vibration isolation mounting base at the bottom of the cyclone separator, and with the help of particle damping technology, it achieves effective vibration isolation during the operation of the cyclone separator, effectively suppressing the transmission of vibration and noise generated by the cyclone separator to the outside. Furthermore, the cyclone separator base is set up in a block installation manner, which reduces the installation difficulty of the double vibration isolation base and further improves the vibration reduction effect on low frequency vibration.

[0032] (2) In this invention, the entire mounting base is divided into a horizontal fixed seat and two vertical fixed seats. During installation, the second vibration damper can be installed in the designated position first, and then the horizontal fixed seat can be installed. At the same time, the vertical fixed seat is fixed in the designated position on the cyclone separator. Finally, the horizontal fixed seat and the vertical fixed seat are aligned, connected by the mounting frame and locked by the mounting part. In this way, the entire mounting base does not need to be installed directly, which reduces the installation weight during the installation process, reduces the installation difficulty, and reduces the installation cost and installation time.

[0033] (3) In this invention, the mounting base can be installed and constructed in sections, and the mounting base can be directly installed on the existing cement ground, which greatly reduces the construction time and modification cost. The vibration damping device has a simple overall structure and is easy to process. It can be pre-assembled and transported to the site for direct installation. The modular installation approach reduces the installation difficulty. During the installation process, it is only necessary to align the groove and the plate and tighten the elongated hole with bolts, which makes the installation simple. In addition, a connecting crossbar is set between the two transverse fixing seats. On the one hand, it can be used for auxiliary fixing to ensure the connection strength. On the other hand, it can accurately control the distance between the two transverse fixing seats and improve the installation accuracy.

[0034] (4) In this invention, the structure of the mounting base is improved. The mounting base is divided into several pieces by a connecting mechanism. The mounting base is installed in sections during loading, which reduces the alignment steps required during installation. At the same time, the installation weight of the mounting base is greatly reduced after being divided into several pieces, which greatly reduces the installation difficulty, increases the construction speed, and reduces the installation cost. In addition, a dual vibration isolation technology is applied and damping particles are filled in, which greatly improves the vibration isolation performance of the vibration damping device and reduces noise generation.

[0035] (5) In this invention, a double vibration isolation structure is set on the mounting base installed at the bottom of the cyclone separator. The vibration generated by the separator body is first transmitted to the first vibration damping component for the first vibration isolation, and then transmitted to the second vibration damping component for the second vibration isolation through the mounting base. This can absorb more vibrations during the operation of the cyclone separator. The entire vibration damping structure has a higher vibration isolation rate and a better vibration isolation effect for low-frequency vibrations. It can greatly reduce the vibration transmission of the cyclone separator to the building.

[0036] (6) In this invention, particle damping is filled in the mounting base. By combining double vibration isolation with particle damping technology, the vibration of the cyclone separator is controlled from both vibration isolation and vibration reduction aspects. This can more effectively absorb and isolate the vibration transmitted from the cyclone separator to the floor, achieving the effect of vibration reduction and noise reduction. At the same time, the whole structure is made of metal material, and its service life and pressure resistance are better than those of rubber vibration isolators, resulting in high reliability. In addition, the entire vibration reduction structure is installed in sections, reducing construction time and cost. Attached Figure Description

[0043] To make the objectives, technical solutions, and advantages of the present invention clearer, a detailed description is provided below in conjunction with the accompanying drawings and specific embodiments. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0044] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0046] This embodiment provides a cyclone separator for starch production and its shock absorption structure, the structure of which is as follows: Figure 1 As shown, the topmost part is the separator body 1, which is the working part of the cyclone separator and also the part that generates vibration. The cyclone separator is mainly installed on a concrete block, and a mounting base 2 needs to be set between the separator body 1 and the concrete block. This serves two purposes: firstly, it facilitates the installation of the cyclone separator, and secondly, it allows for the installation of vibration dampers on the mounting base 2 to reduce vibration and noise.

[0047] like Figures 1 to 3As shown, the mounting base 2 mainly includes a transverse fixing seat 21 and a longitudinal fixing seat 22 connected end to end to form a frame structure. The two transverse fixing seats 21 are set parallel to each other on a cement block parallel to the distribution direction of the separator body 1, while the two longitudinal fixing seats 22 are set perpendicular to the distribution direction of the separator body 1.

[0048] A transverse frame 11 and a longitudinal frame 12 are also provided at the bottom of the separator body 1. The transverse frame 11 is fixed to the bottom of the separator body 1 and is used to connect and fix several cyclone separators. At the same time, the two ends of the transverse frame 11 are fixed relative to the longitudinal fixing seat 22. The longitudinal frame 12 is fixed to the bottom of the transverse frame 11, and its two ends are fixed to the transverse fixing seat 21. In this way, the vibration generated by the separator body 1 can be transmitted to the mounting base 2 through the transverse frame 11 and the longitudinal frame 12.

[0049] like Figure 2 and Figure 3 As shown, for ease of installation, the mounting base 2 is a modular structure, and the components are fixed together by the mounting part 24. Mounting brackets are fixed to both ends of the transverse fixing base 21, with the top of the mounting bracket recessed inward to form a groove 241. The longitudinal fixing base 22 has integrally formed insert plates 242 at both ends. One side of the groove 241 is open, and the insert plates 242 are fitted into the groove 241. Several elongated holes 245 are formed on the insert plates 242, and several bolts 244 are positioned within the groove 241 corresponding to the positions of the elongated holes 245. The bolts 244 are perpendicular to the horizontal plane. During connection, the bolts 244 are fitted into the elongated holes 245 and tightened.

[0050] A support plate 243 is provided on the side of the mounting bracket facing the mounting base 2. The support plate 243 extends downward from the opening of the groove 241 and has a right-angle bend shape. During connection, the support plate 243 can lift the bottom end of the longitudinal fixing seat 22, assisting in fixing the longitudinal fixing seat 22. A connecting crossbar 25 is also provided in the middle of the two transverse fixing seats 21, and both ends of the connecting crossbar 25 are fixed to the transverse fixing seats 21 respectively. The connecting crossbar 25 can determine the distance between the two transverse fixing seats 21 and also improve the connection firmness.

[0051] like Figure 2 and Figure 4 As shown, a first vibration damper 3 is provided inside the mounting base 2, and a mounting groove 26 is also provided at the bottom of the mounting bracket, with a second vibration damper 4 provided inside the mounting groove 26. This invention improves the vibration damping effect of the vibration damping device through a dual vibration isolation method. The first vibration damper 3 can be provided in two ways: the first is to use an existing vibration isolator, and the second is to create a cavity 246 inside the mounting base 2 and fill it with damping particles 5 to form vibration isolation.

[0052] When the mounting base 2 has a cavity 246, there are several cavities 246. The type, particle size, and filling rate of the damping particles 5 filled in adjacent cavities 246 can be exactly the same, partially the same, or completely different. When the damping particles 5 are the same, production costs can be reduced, while when the damping particles 5 are different, the vibration reduction effect on vibrations of different frequencies can be improved.

[0053] The damping particles 5 include, but are not limited to, iron-based particles or ceramic particles. The surface friction factor of the damping particles 5 used is 0.01 to 0.99, the surface restitution coefficient is 0.01 to 1, and the density is 0.1 to 30 g / cm³. 3 The filling rate is 60%–90%.

[0054] Particle damping technology mainly uses particles filled in the cavity of a structure to provide a damping effect to the structure through inelastic collisions and frictional energy dissipation between particles and between particles and the damper wall, thereby suppressing the vibration of the structure.

[0055] When particle damping technology is applied to this invention, it can effectively reduce low-frequency vibrations, reduce and isolate vibrations generated at the bottom of the separator body 1 and the connecting row 6, effectively reduce the low-frequency vibrations of 50Hz and its harmonics generated during the operation of the cyclone separator, thereby effectively suppressing the transmission of vibrations and noise generated by the cyclone separator to the outside.

[0056] When both the first damping element 3 and the second damping element 4 are ordinary vibration isolators, the type of vibration isolator may include, but is not limited to, spring vibration isolators, rubber vibration isolators, air spring vibration isolators, wire rope vibration isolators, or spring-rubber composite vibration isolators, etc., and the selection shall be made according to the actual situation. The first damping element 3 shall be divided into at least four blocks, and the second damping element 4 shall be divided into at least four blocks.

[0057] The main working process of this application is as follows:

[0058] This application uses a double vibration isolation mounting base 2, which is placed directly on an existing concrete block. Several second vibration damping components 4 are directly installed between the concrete block and the base 2, while a first vibration damping component 3 is directly installed between the base 2 and the cyclone separator. This double vibration isolation technology improves the vibration isolation rate and the isolation effect for low-frequency vibrations. Simultaneously, the inelastic collisions and friction between the damping particles 5 within the base 2 and between the damping particles 5 and the sidewalls further dissipate vibration energy, further reducing the vibration transmitted from the cyclone separator's connecting row 6 to the wall. The second vibration damping components 4 are composed of several parts, which are bolted together with the first vibration damping component 3 and the mounting base 2 to form a single unit.

[0059] In addition to improvements at the bottom of the separator body 1, the present invention also improves the structure of the connecting row 6 connected to the top of the separator body 1. For example... Figure 5 As shown, the separator body 1 is connected to the wall via a connecting strip 6. A mounting bracket 61 is fixed on the wall, and the connecting strip 6 is fixed on the mounting bracket 61. The connecting strip 6 and the separator body 1 are connected by several parallel connecting plates 62.

[0060] The connecting plate 62 is made of elastic metal material. The connecting plate 62 includes a vertical section 622 fixed to the separator body 1, a horizontal section 621 connected to the connecting row 6, and a connecting section 623 connecting the vertical section 622 and the horizontal section 621. The vertical section 622, the horizontal section 621 and the connecting section 623 are rounded.

[0061] The connection between the separator body 1 and the connecting row 6 achieved by this connection structure can be buffered by the connecting plate 62 when the separator body 1 vibrates, thereby reducing the vibration of the cyclone separator on the connecting row 6 and thus reducing the vibration of the connecting row 6 on the wall.

[0062] The present invention also completed the installation test of the solution, as detailed in the embodiments.

[0063] In this embodiment, the noise generated by the separator body is mainly concentrated in the low frequency range of 400 Hz, appearing at 50 Hz and its harmonics, which is a very obvious characteristic of cyclone separator vibration and noise.

[0064] Therefore, in this embodiment, a dual vibration reduction and segmented installation vibration reduction structure is provided at the bottom of the separator body, and damping particles are filled to further enhance the vibration reduction and isolation effect of the mounting base. At the same time, the rigid grounding device between the bottom of the cyclone separator and the floor is changed to a soft connection to reduce the transmission of vibration to the floor.

[0065] In addition, the vibration at the connection point between the connector and the wall is also very large. Since the connector is fixed to the wall, the vibration of these two parts can be transmitted directly along the wall to the second floor or even higher floors. Therefore, the connector needs to be modified accordingly.

[0066] This involves changing the structure of the connecting bar and using connecting plates for flexible connections instead of the original rigid connections, thereby reducing the vibration transmitted from the cyclone separator to the connecting bar.

[0067] Before and after the renovation, vibration data of the factory building, walls, and corresponding locations on the second floor were tested and collected. By comparing the vibration data before and after the renovation, the actual effect of the vibration reduction and noise reduction renovation of the factory building can be illustrated. The specific data is shown in Table 1.

[0068] Table 1 Comparison of vibration data at various locations before and after modification.

[0069]

[0070] As shown in Table 1, the overall vibration isolation effect of each measuring point is good after the modification, and the vibration isolation rate is high.

[0071] Next, for different measuring points, the vibration spectrum before and after the modification was compared to further illustrate the vibration isolation effect of the modified invention.

[0072] The first step was to compare the vibration data of the factory floor.

[0073] Finally, in accordance with the test methods specified in GB 22337-2008 Social Life Environmental Noise Emission Standard, this invention uses a sound level meter to collect noise data from different locations, such as inside the cyclone separator room and inside the office on the second floor of the factory.

[0074] The indoor noise emission limits for structure-transmitting equipment specified in GB 22337-2008 are shown in Table 2.

[0075] Table 2 GB22337-2008 Indoor Noise Emission Limits

[0076]

[0077] The second-floor office modified in this invention belongs to Class B rooms as specified in GB 22337-2008. The noise data comparison between the cyclone separator room and the second-floor activity room before and after the modification is shown in Table 3.

[0078] Table 3 Comparison of noise data at various locations before and after the renovation

[0079]

[0080] As shown in Table 3, the noise levels in the second-floor office decreased from 43.92 dB and 41.51 dB to 37.42 dB and 36.48 dB, respectively, all of which meet the requirements of GB22337-2008.

[0081] In summary, this invention has an excellent vibration reduction and isolation effect in factory buildings. It has implemented vibration reduction and isolation treatments at every path of vibration transmission. Compared with traditional factory building vibration reduction and noise reduction renovations, this invention can more efficiently reduce vibration transmission and achieve better vibration reduction and noise reduction effects. Comparing the vibration amplitude on the factory floor, connecting walls, and second-floor floor before and after the renovation, there is a significant decrease at each location, especially at the characteristic frequency peaks generated by the cyclone separator at 100Hz, 200Hz, 300Hz, and 400Hz, where there is a good peak-shaving effect.

[0082] In addition to the embodiments described above, the present invention may have other implementations. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by the present invention.
