Description

Technical Field

[0001] This utility model relates to the field of accelerator production technology, and more specifically, to a novel accelerator raw material screening machine. Background Technology

[0002] A raw material screening machine is a device that uses a screen to separate materials. In accelerator production lines, it is typically installed in the raw material pretreatment stage to screen and classify the raw materials entering the production line. Screening removes impurities, large pieces of material, and materials that do not meet particle size requirements, thus ensuring the smooth operation of subsequent production processes.

[0003] Existing raw material screening machines generally involve vibration of the entire device to screen the raw materials inside. This structure causes the vibration and noise inside the device to be transmitted to the external environment, affecting people and the environment. Furthermore, it cannot collect floating dust from the raw materials, causing the dust to escape into the external environment and pose a hazard to personnel.

[0004] A Chinese utility model patent, titled "A Raw Material Screening Machine" and with publication number CN218610364U, includes a supporting base plate with a supporting mechanism mounted on it. A screening box is mounted on the supporting mechanism, and a vibration mechanism is installed between the supporting base plate and the screening box. A screening mechanism is located inside the screening box. This utility model performs small-amplitude, rapid up-and-down vibrations, which in turn drive a rubber rod to rotate reciprocally, striking the separating plate. This not only improves screening efficiency but also prevents the mesh from clogging.

[0005] Although this invention can improve screening efficiency, it still cannot isolate the vibration and noise generated during vibration, nor can it collect floating raw material dust. Utility Model Content

[0006] The purpose of this application is to provide a novel quick-setting agent raw material screening machine, which solves the technical problems of collecting floating dust during quick-setting agent raw material screening and reducing the vibration and noise transmission of the device.

[0007] To solve the above-mentioned technical problems, the solution adopted in this application is as follows:

[0008] A novel quick-setting agent raw material screening machine includes a cylinder with a feed inlet at the top and screening plates inside the cylinder. The screening plates are connected to a vibration assembly, and the screening plates do not contact the inner wall of the cylinder. The vibration assembly is connected to the inner wall of the cylinder through a buffer assembly.

[0009] Preferably, the screening plate includes a coarse-hole screen plate and a fine-hole screen plate, with the coarse-hole screen plate and the fine-hole screen plate disposed below the feed inlet and the coarse-hole screen plate located above the fine-hole screen plate.

[0010] Preferably, the vibration end of the vibration component is connected to a buffer adjustment component, which includes an elastic element. The elastic element is connected to the vibration end of the vibration component and a displacement element, respectively. The direction of the elastic force applied by the elastic element to the vibration component through the displacement element is opposite to the direction of the force applied by the buffer component to the vibration component when the vibration component vibrates.

[0011] Preferably, the cylinder is provided with a dust collection assembly, which includes a dust collection pipe. A dust collection pipe is provided above both the coarse-pore sieve plate and the fine-pore sieve plate. The dust collection pipe is located on the cylinder and has an internal cavity. Both ends of the cavity extend into the cylinder. A filter plate is provided inside the cavity. The cavity is divided into two independent chambers by the filter plate. A hot air assembly is provided in one chamber, and the other chamber is a dust collection chamber.

[0012] Preferably, the screening plate is further provided with a scraper assembly.

[0013] Preferably, the scraper assembly includes a rotating component, which is fixedly disposed at the bottom of the screening plate. A rotating shaft is disposed on the rotating end of the rotating component. The rotating shaft rotates vertically and passes through the coarse-hole screen plate and the fine-hole screen plate. Multiple scrapers are disposed on the rotating shaft. Corresponding scrapers are slidably disposed on the upper surface of both the coarse-hole screen plate and the fine-hole screen plate. An inclined plate is disposed at the outermost rotating end of the scraper. The inclined plate is close to the inner wall of the cylinder but does not contact it.

[0014] Preferably, the coarse-hole sieve plate and the fine-hole sieve plate have a plurality of sieve holes running through their surfaces, and the surfaces of the coarse-hole sieve plate and the fine-hole sieve plate are both arc-shaped, with the outer convex direction of the arc facing the feed inlet.

[0015] Preferably, the screening plate further includes a clamping plate and a clamping groove. The outer edges of the coarse-hole screen plate and the fine-hole screen plate are fixedly connected to the clamping plate. The clamping groove is located on the inner wall of the cylinder. The clamping plate is matched and connected to the groove. There is a gap between the surface of the clamping plate and the surface of the clamping groove.

[0016] Preferably, the vibration assembly includes a mounting plate, on which a rotating motor is mounted, and heavy blocks are mounted on both vertical rotating ends of the rotating motor.

[0017] Preferably, the top surface of the mounting plate is vertically provided with multiple fixing rods, which pass through the coarse-hole sieve plate and the fine-hole sieve plate and are fixedly connected to the two sieve plates.

[0018] Preferably, one end of the buffer assembly is fixedly connected to the bottom surface of the mounting plate, and the other end of the buffer assembly is fixedly connected to the inner wall of the cylinder.

[0019] Preferably, the buffer adjustment assembly further includes a baffle, which is fixedly mounted on the slide column. The slide column is fixed to the displacement end of the displacement member. The slide column passes vertically through the mounting plate. An elastic member is provided on the slide column above the mounting plate, and a baffle is provided on the slide column below the mounting plate.

[0020] Preferably, the dust collection assembly further includes a first duct ring plate and a second duct ring plate, both of which are disposed on the inner wall of the cylinder.

[0021] Preferably, the first air duct ring plate is located above the coarse-hole screen plate and below the corresponding dust collection pipe, and the upper surface of the first air duct ring plate is flat.

[0022] Preferably, the second air duct ring plate is located above the fine-pore sieve plate and below the corresponding dust collection pipe. The upper surface of the second air duct ring plate is inclined, and the inclined bottom end of the inclined surface is close to the upper surface of the fine-pore sieve plate.

[0023] The technical solution of this application has at least the following advantages and beneficial effects:

[0024] In this utility model, by setting up screening plates and vibration components, the vibration components are used to vibrate the multi-layer screen plates to achieve multi-layer screening. The vibration components are connected to the cylinder through a buffer component, and the screening plates do not contact the cylinder. Therefore, the vibration and noise transmitted to the external environment during vibration screening are reduced, thus reducing the impact on external personnel and the environment.

[0025] In this invention, by setting a buffer adjustment component, the vibration amplitude of the vibration component can be adjusted. Therefore, when the screen plate vibrates, if the vibration amplitude is too large, the quick-setting agent raw material will collide with the inner wall of the cylinder, causing damage to the device.

[0026] In this invention, by setting up a dust collection component and a hot air component, hot air is circulated and blown into the inside of the cylinder through the air duct. While keeping the quick-setting agent raw material dry, the floating raw material dust is carried into the dust collection chamber by the wind and collected, thus preventing the dust from escaping.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] Example

[0037] Please refer to Figures 1-5This utility model provides a novel quick-setting agent raw material screening machine, including a cylinder 1, a feed inlet 2, screening plates 3, a vibration assembly 4, a buffer assembly 5, a buffer adjustment assembly 6, a scraper assembly 7, a hot air assembly 8, and a dust collection assembly 9.

[0038] Furthermore, a feed inlet 2 is provided at the top of the cylinder 1, and a screening plate 3 is provided inside the cylinder 1. The quick-setting agent raw material is poured into the cylinder 1 from the feed inlet 2 and screened by the screening plate 3 inside.

[0039] The screening plate 3 includes a coarse-pore screen plate 301, a fine-pore screen plate 302, and a collection box 303. The coarse-pore screen plate 301 and the fine-pore screen plate 302 are located below the feed inlet 2. The coarse-pore screen plate 301 is located above the fine-pore screen plate 302, and the fine-pore screen plate 302 is located above the collection box 303. The raw material falling from the feed inlet 2 will pass through the coarse-pore screen plate 301 and the fine-pore screen plate 302 in sequence, screening the quick-setting agent raw materials of different particle sizes and temporarily storing them in the coarse-pore screen plate 301, the fine-pore screen plate 302, and the collection box 303.

[0040] Furthermore, the screening plate 3 is connected to the vibration assembly 4. The vibration assembly 4 drives the screening plate 3 to vibrate, which quickly screens the quick-setting agent raw material. The screening plate 3 does not contact the inner wall of the cylinder 1. The vibration assembly 4 is connected to the inner wall of the cylinder 1 through the buffer assembly 5. Therefore, the vibration displacement of the screening plate 3 driven by the vibration assembly 4 will be offset by the buffer displacement of the buffer assembly 5. The vibration force will not be transmitted to the cylinder 1, thus avoiding the vibration of the entire device and generating large noise.

[0041] Furthermore, the vibration end of the vibration component 4 is connected to a buffer adjustment component 6, which can apply elastic force to the vibration end. Through the interaction force between the elastic force and the buffer component 5 on the vibration component 4, the vibration amplitude of the vibration end is automatically adjusted, thereby changing the screening frequency of the screening plate 3.

[0042] Furthermore, a dust collection assembly 9 is also provided on the cylinder 1. The dust collection assembly 9 is located above the screening plate 3. The hot air assembly 8 inside the cylinder 1 blows hot air into the cylinder 1 to perform a simple drying effect on the inside of the cylinder 1. The air duct drives the airflow to flow in a circular direction to collect the raw material dust floating in the cylinder 1.

[0043] Please refer to Figure 2 In this embodiment, the vibration assembly 4 includes a mounting plate 401, a rotating motor 402, a heavy block 403, a fixed ring plate 404, and a fixed rod 405.

[0044] Specifically, the mounting plate 401 is installed inside the cylinder 1, and a fixing ring plate 404 is fixedly installed on the lower part of the inner wall of the cylinder 1. Multiple buffer components 5 are fixedly connected to the bottom and side walls of the mounting plate 401. The multiple buffer components 5 are evenly arranged in a circular pattern on the mounting plate 401. The other end of the buffer component 5 on the bottom surface of the mounting plate 401 is fixedly connected to the fixing ring plate 404. Here, the displacement direction of the buffer component 5 during buffering is vertical. The other end of the buffer component 5 on the side wall of the mounting plate 401 is fixedly connected to the inner wall of the cylinder 1. Here, the displacement direction of the buffer component 5 during buffering is horizontal. The multiple buffer displacements are used to fully absorb the vibration displacement from the vibrating end.

[0045] Among them, the buffer component 5 is set as a spring. The spring can not only elastically displace, but also elastically bend, which can buffer and offset vibration displacement at more angles.

[0046] The mounting plate 401 is fixedly equipped with a rotating motor 402. Both vertical ends of the rotating motor 402 are rotating ends, and heavy blocks 403 are fixedly equipped on each rotating end. The heavy blocks 403 are eccentrically positioned on the rotating ends. When the rotating motor 402 rotates, the eccentric heavy blocks 403 rotate in a circular motion. The inertial force of their rotation causes the heavy blocks 403 at the two rotating ends of the rotating motor 402 to oscillate at different swing positions, thereby generating vibration. The vibration is transmitted to the mounting plate 401, causing it to vibrate and become the vibrating end of the vibration component 4.

[0047] The top surface of the mounting plate 401 is vertically fixed with multiple fixing rods 405. The fixing rods 405 pass through the collection box 303, the coarse-hole screen plate 301, and the fine-hole screen plate 302 in the screening plate 3 and are fixedly connected to the two screen plates and the collection box 303. When the mounting plate 401 vibrates, the vibration is directly transmitted to the two screen plates through the fixing rods 405, causing the screen plates to vibrate and allowing the quick-setting agent raw material to quickly pass through the screen holes of the screen plates for screening.

[0048] Please refer to Figure 2 In this embodiment, the screening plate 3 includes a coarse-hole screen plate 301, a fine-hole screen plate 302, a collection box 303, a card plate 304, and a card slot 305.

[0049] Specifically, the coarse-hole screen plate 301 and the fine-hole screen plate 302 have several screen holes running through their surfaces. The screen holes of the coarse-hole screen plate 301 are larger than those of the fine-hole screen plate 302. The surfaces of both the coarse-hole screen plate 301 and the fine-hole screen plate 302 are arc-shaped, with the outer convex direction of the arc facing the feed inlet 2.

[0050] Preferably, when the accelerator raw material falls onto the sieve plate, the arc-shaped plate surface will vibrate the accelerator raw material from the center of the sieve plate to the outer edge of the sieve plate during the vibration process. During the movement of the accelerator raw material, the accelerator raw material will come into contact with more sieve holes and be vibrated and screened, thereby improving the screening efficiency.

[0051] A ring of clamping plates 304 is fixedly connected to the outer edge of the coarse-hole sieve plate 301 and the fine-hole sieve plate 302. A ring of clamping grooves 305 is fixed on the inner wall of the cylinder 1. The clamping plates 304 and the grooves are matched and connected together, but the two will not contact each other when the device is not working. There is a gap between the plate surface of the clamping plate 304 and the groove surface of the clamping groove 305.

[0052] Preferably, when the device is operating and the vibration component 4 vibrates, the clamping plate 304 will also vibrate and displace within the clamping slot 305. The clamping slot 305 will limit the clamping plate 304 from making excessive displacement. During this process, the surface of the clamping plate 304 will come into contact with the groove surface of the clamping slot 305 when the vibration displacement is large. It is worth noting that an elastic pad is provided on the groove surface of the clamping slot 305 to prevent the clamping plate 304 from colliding hard with the clamping slot 305, which could damage the clamping plate 304 and the clamping slot 305 and cause vibration of the cylinder 1.

[0053] Please refer to Figure 2 and Figure 5 In this embodiment, the buffer adjustment component 6 includes a sliding column 601, an elastic element 602, a displacement element 603, and a baffle 604.

[0054] Specifically, the sliding column 601 slides vertically through the mounting plate 401. The bottom of the sliding column 601 is fixedly connected to the displacement end of the displacement member 603, which is fixed to the bottom of the cylinder 1. An elastic member 602 is provided on the sliding column 601 above the mounting plate 401. One end of the elastic member 602 is fixedly connected to the top of the sliding column 601, and the other end of the elastic member 602 is fixedly connected to the upper surface of the mounting plate 401. A baffle 604 is fixedly provided on the sliding column 601 below the mounting plate 401.

[0055] It is worth noting that the displacement component 603 is set as an electric cylinder, the elastic component 602 is set as a spring, and the diameter of the through hole through which the sliding column 601 passes through the mounting plate 401 is larger than the diameter of the sliding column 601, so as to ensure that the vertical displacement of the sliding column 601 will not be interfered with when the mounting plate 401 vibrates.

[0056] Preferably, when the vibration component 4 vibrates normally, the buffer adjustment component 6 does not work, the displacement end of the displacement member 603 extends, the elastic member 602 applies the minimum elastic force to the mounting plate 401, and when the mounting plate 401 vibrates, the vibration displacement will drive the buffer component 5 (spring) to perform elastic displacement, and therefore it will be subjected to the reverse elastic force from the buffer component 5, which will cancel out the vibration transmitted to the buffer component 5.

[0057] When the vibration amplitude of the vibration component 4 is large, the accelerator raw material on the screen plate will be vibrated to a higher height, thus colliding with the inner wall of the cylinder 1 above the screen plate and causing damage to the cylinder 1. At this time, the buffer adjustment component 6 starts to work, the displacement component 603 drives the sliding column 601 to move down, and the elastic component 602 applies an increasing elastic force to the mounting plate 401. When the mounting plate 401 vibrates, it will not only be subjected to the reverse force of the buffer component 5, but also to the elastic force from the elastic component 602. The combined elastic displacement of the two components will reduce the vibration displacement and vibration amplitude of the mounting plate 401, thereby reducing the vibration height of the accelerator raw material on the screen plate and ensuring the safety of the device.

[0058] Please refer to Figure 2 and Figure 3 In this embodiment, the dust collection assembly 9 includes a dust collection pipe 901, a first duct ring plate 902, a second duct ring plate 903, an opening 904, a dust collection chamber 905, and a filter plate 906.

[0059] Specifically, a dust collection pipe 901 is provided above both the coarse-pore sieve plate 301 and the fine-pore sieve plate 302. The dust collection pipe 901 is fixedly installed on the outer wall of the cylinder 1. The inside of the dust collection pipe 901 is a cavity, and the two ends of the cavity are through-holes 904. The through-holes 904 penetrate the inside of the cylinder 1. A filter plate 906 is fixedly installed inside the cavity. The filter plate 906 intercepts the cavity surface and divides the cavity into two independent chambers through the filter plate 906. One chamber is equipped with a hot air assembly 8, which blows hot air into the inside of the cylinder 1. The other chamber is set as a dust collection chamber 905. The hot air flowing inside the cylinder 1 will carry floating dust into the dust collection chamber 905, and then be filtered by the filter plate 906. The hot air enters the hot air assembly 8 and is then blown into the inside of the cylinder 1 to realize hot air circulation.

[0060] The hot air assembly 8 includes a fan assembly 801 and a heating assembly 802. The fan assembly 801 blows air, and the heating assembly 802 continues to heat. Both components are basic common knowledge that can be grasped by those skilled in the art, so they will not be described in detail in the specification.

[0061] Both the first air duct ring plate 902 and the second air duct ring plate 903 are fixedly installed on the inner wall of the cylinder 1 to guide the hot air blown into the cylinder 1 by the hot air assembly 8, so as to facilitate the introduction into the dust collection chamber 905 to collect the floating dust generated by the quick-setting agent raw material carried in the hot air.

[0062] The first air duct ring plate 902 is located above the coarse-pore screen plate 301 and below the corresponding dust collection pipe 901, and the upper surface of the first air duct ring plate 902 is flat; the second air duct ring plate 903 is located above the fine-pore screen plate 302 and below the corresponding dust collection pipe 901, and the upper surface of the second air duct ring plate 903 is inclined, with the inclined bottom end of the inclined surface close to the upper surface of the fine-pore screen plate 302.

[0063] Among them, the annular plate surface of the first air duct ring plate 902 is located outside the feed inlet 2 and will not block the quick-setting agent raw material falling from the feed inlet 2. Therefore, the plate surface is set as a plane. The annular plate surface of the second air duct ring plate 903 is located between the coarse hole screen plate 301 and the fine hole screen plate 302. Its plate surface will block the quick-setting agent raw material falling from the upper coarse hole screen plate 301. Therefore, the plate surface is set as an inclined surface so that the quick-setting agent raw material can directly fall onto the fine hole screen plate 302.

[0064] Please refer to Figure 2 and Figure 4 In this embodiment, the screening plate 3 is also provided with a scraper assembly 7, which includes a rotating shaft 701, a rotating component 702, a scraper 703, and an inclined plate 704.

[0065] Specifically, the rotating component 702 is fixedly installed at the bottom of the collection box 303, and a rotating shaft 701 is fixedly installed on the rotating end of the rotating component 702. The rotating shaft 701 rotates vertically through the collection box 303, the coarse-pore sieve plate 301 and the fine-pore sieve plate 302. Multiple scrapers 703 are fixedly installed on the rotating shaft 701. The upper surfaces of the coarse-pore sieve plate 301 and the fine-pore sieve plate 302 are slidably equipped with corresponding scrapers 703. However, when the rotating component 702 drives the scrapers 703 to rotate relative to the sieve plate, the scrapers 703 will scrape off the quick-setting agent raw material attached to the surface of the sieve plate, causing the quick-setting agent raw material to vibrate to the outer edge of the sieve plate.

[0066] An inclined plate 704 is fixedly installed at the outermost rotating end of the scraper 703. The inclined bottom end of the inclined plate 704 slides in contact with the surface of the screen plate, and the outer edge of the inclined plate 704 does not contact the inner wall of the cylinder 1. A sealing door is provided on the inner wall of the cylinder 1 between the screen plate and the air duct ring plate.

[0067] When the sieve plate vibrates, the scraper assembly 7 vibrates together with the screening plate 3. When the sieve plate screens raw materials of different particle sizes into the coarse-hole sieve plate 301, the fine-hole sieve plate 302 and the collection box 303, the vibration assembly 4 stops vibrating, the sealing door opens, and the inclined plate 704 rotates the accelerator raw material on the outer edge of the corresponding sieve plate out of the sealing door for collection, so as to avoid the accumulation of too much screened accelerator raw material in the sieve plate.

[0068] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art will fully understand how to implement the technical solution of this utility model based on the above description. The scope of this utility model is defined by the appended claims.
