Description
Technical Field
[0001] This utility model belongs to the field of powder sorting technology, and specifically relates to a powder sorting device capable of multi-stage sieving. Background Technology
[0002] Refractory materials refer to a class of inorganic non-metallic materials with a refractoriness of not less than 1580 degrees Celsius, characterized by maintaining stable physical and chemical properties under high-temperature environments. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate industry, power industry, and other industrial fields. They play an indispensable role as structural and lining materials in high-temperature process equipment, and are crucial to the development of high-temperature industries. Refractory powder is one of the key components of refractory materials; by selecting appropriate refractory powder, the performance of refractory materials can be adjusted to meet the needs of different working environments.
[0003] In existing technologies, different refractory materials have different requirements for the particle size of raw materials. Multi-stage screening and sorting devices are usually used to obtain a particle size distribution that meets the product requirements, thereby improving the quality and performance of the product. However, the existing multi-stage screening and sorting devices have fixed internal screening screens, which are inconvenient to disassemble and replace, and cannot meet diverse needs, making them unsuitable for use.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model is a powder sorting device capable of multi-stage screening, including a box body. Multiple sets of fixing plates are symmetrically installed on the inner wall of the box body. Each set of fixing plates is equipped with a screening structure. The screening structure divides the internal space of the box body into multiple chambers from top to bottom. The screening structure includes a guide component, which is slidably installed on the fixing plate. A C-shaped mounting frame is installed on the guide component, and a retractable screening screen is installed on the C-shaped mounting frame. One end of the screening screen is movably engaged with a locking component, which is installed on one side of the box body. The screening structure also includes a vibration component, which is installed on one side of the box body. The vibration component is used to make the C-shaped mounting frame vibrate on the fixing plate through the guide component.
[0006] The guide assembly includes multiple sliding rods, all of which are slidably mounted on the fixed plate. Each sliding rod is surrounded by a spring. A C-shaped mounting frame is mounted on the upper end of the sliding rods. The C-shaped mounting frame has a slot, and the screening screen can slide and engage with the slot.
[0007] The vibration assembly includes a wedge block mounted on the upper surface of the C-shaped mounting frame. The vibration assembly also includes a rotating shaft, which is rotatably mounted on one side of the housing. A drive disk is mounted on one end of the rotating shaft, and a cam is mounted on the other end. The cam can be adapted to the inclined surface of the wedge block. The drive disk is used to connect to an external drive assembly so that the external drive assembly can drive the rotating shaft to rotate, thereby causing the cam to move in coordination with the wedge block, which in turn causes the C-shaped mounting frame to vibrate.
[0008] The locking assembly includes a locking plate, with symmetrical positioning grooves on the inner side of the locking plate. A snap-fit seat is slidably installed in the positioning groove, and one end of the screening screen is snap-fitted onto the snap-fit seat.
[0009] A material discharge hopper is installed at the top of the box, and the material discharge hopper is connected to the inside of the box.
[0010] Multiple discharge guide plates are installed on one side of the box. Each discharge guide plate communicates with a chamber inside the box. A baffle is slidably installed on the inner wall of the discharge guide plate, which can completely close the part of the discharge guide plate that communicates with the chamber inside the box.
[0011] The locking plate is bolted to one side of the housing, and a handle is installed on the outside of the locking plate.
[0012] This utility model has the following beneficial effects:
[0013] 1. This utility model first releases the bolt connection between the locking plate and the housing, then pulls the handle to remove the locking plate and the locking seat from the housing. This prevents the locking seat from locking one end of the screening mesh, allowing the screening mesh to slide out of the housing from the C-shaped mounting frame. By sliding the locking seat in the positioning groove, the screening mesh and the locking seat can slide within the positioning groove when the C-shaped mounting frame causes the screening mesh to vibrate. This device ensures that the screening mesh can vibrate, improving work efficiency, while also allowing for flexible replacement of screening meshes with different apertures to meet diverse needs and be applicable to various scenarios.
[0014] 2. This utility model uses a drive disc to drive the rotating shaft and cam to rotate, so that the cam intermittently contacts the inclined surface of the inclined block as it rotates. This causes the C-shaped mounting frame and the sliding rod to slide downward on the fixed plate, which in turn causes the spring to compress and deform. As a result, the C-shaped mounting frame and the screening screen will vibrate under the action of the cam and the inclined block, which allows the refractory powder to be screened and sorted more effectively, thus improving work efficiency.
[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-8 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0026] Please see Figures 2-5 As shown:
[0027] This embodiment provides a multi-stage sieving powder sorting device, including a housing 1. Multiple sets of fixing plates 2 are symmetrically installed on the inner wall of the housing 1. Each set of fixing plates 2 has a set of sieving structures 3 installed on it. The sieving structures 3 divide the internal space of the housing 1 into multiple chambers from top to bottom. The sieving structures 3 include a guide assembly 4, which is slidably mounted on the fixing plates 2. A C-shaped mounting frame 5 is mounted on the guide assembly 4, and a retractable sieving screen 6 is mounted on the C-shaped mounting frame 5. One end of the sieving screen 6 is movably engaged with a locking assembly 7. The upper aperture of the sieving screen 6 in each set of sieving structures 3 is larger than the lower aperture, so as to screen out powders of different particle sizes. The locking assembly 7 is installed on one side of the housing 1. The sieving structures 3 also include a vibration assembly 8, which is installed on one side of the housing 1. The vibration assembly 8 is used to cause the C-shaped mounting frame 5 to vibrate on the fixing plates 2 via the guide assembly 4.
[0028] In practical use, refractory powder is first added from the top of the box 1. The powder falls downward under the action of gravity. Then, the external power component drives the vibration component 8 to rotate. Through the action of the guide component 4, the vibration component 8 can drive the C-shaped mounting frame 5 to vibrate on the fixed plate 2. The C-shaped mounting frame 5 drives the screening screen 6 to vibrate. As the screening screen 6 vibrates, the powder with a particle size smaller than the current aperture of the screening screen 6 passes through the screening screen 6 and enters the next chamber. The powder with a particle size larger than the aperture remains in the current chamber. Thus, multi-stage screening of the powder is achieved by using screening screens 6 with different apertures in different chambers.
[0029] When it is necessary to replace the screening screen 6 with a different aperture, operate the locking component 7 to remove it from the housing 1 to unlock the screening screen 6. This allows the screening screen 6 to be pulled off the C-shaped mounting frame 5. Then, install the screening screen 6 with the required aperture on the C-shaped mounting frame 5, and re-fix the locking component 7 on the housing 1 so that the screening screen 6 is re-engaged with the locking component 7. The screening work can then continue. The screening screen 6 can slide on the locking component 7 without affecting the vibration movement of the screening screen 6. Thus, this device can flexibly replace screening screens 6 with different apertures without affecting the vibration operation of the screening screen 6, meeting diverse needs and applicable to various scenarios.
[0030] like Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, the guide assembly 4 includes multiple sliding rods 9, all of which are slidably mounted on the fixed plate 2. A spring 10 is mounted around each sliding rod 9. A C-shaped mounting frame 5 is mounted on the upper end of the sliding rods 9, and a slot 11 is provided on the C-shaped mounting frame 5, allowing the screening screen 6 to slide smoothly into the slot 11. The vibration assembly 8 includes an inclined block 12 mounted on the upper surface of the C-shaped mounting frame 5. The vibration assembly 8 also includes a rotating shaft 13, which is rotatably mounted on one side of the housing 1. A drive disk 14 is mounted on one end of the rotating shaft 13, and a cam 15 is mounted on the other end. The cam 15 is adapted to the inclined surface of the inclined block 12. The drive disk 14 is used to interact with the external... The external drive assembly is connected to the drive assembly so that the external drive assembly can drive the rotating shaft 13 to rotate. When the external power assembly drives the drive disk 14 to rotate, the rotation of the drive disk 14 will also drive the rotating shaft 13 and the cam 15 to rotate. As the cam 15 rotates, it will intermittently contact the inclined surface of the inclined block 12. Under the guidance of the sliding rod 9, the C-shaped mounting frame 5 can slide downward on the fixed plate 2, causing the spring 10 to compress and deform. In turn, the C-shaped mounting frame 5 and the screening screen 6 will vibrate under the action of the cam 15 and the inclined block 12, so that the refractory powder can be screened and sorted more effectively, improving work efficiency.
[0031] like Figure 4 , Figure 6 , Figure 8 As shown, the locking assembly 7 includes a locking plate 16. The inner side of the locking plate 16 is symmetrically provided with positioning grooves 17. A snap-fit seat 18 is slidably installed in the positioning groove 17. One end of the screening screen 6 is snap-fitted onto the snap-fit seat 18. The locking plate 16 is bolted to one side of the housing 1. A handle 22 is installed on the outer side of the locking plate 16. When it is necessary to replace the screening screen 6, first release the bolt connection between the locking plate 16 and the housing 1, and then pull the handle 22 to remove the locking plate 16 and the snap-fit seat 18 from the housing 1, so that the snap-fit seat 18 no longer snaps onto one end of the screening screen 6, so that the screening screen 6 can be slid out of the housing 1 from the C-shaped mounting frame 5, thereby achieving flexible replacement of screening screens 6 with different apertures.
[0032] When the screening screen 6 is installed on the C-shaped mounting frame 5 and snapped onto the snap-fit seat 18 for screening and sorting refractory powder, the snap-fit seat 18 is slidably installed in the positioning groove 17. This allows the screening screen 6 and the snap-fit seat 18 to slide within the positioning groove 17 when the C-shaped mounting frame 5 drives the screening screen 6 to vibrate. This avoids affecting the vibration of the screening screen 6 and ensures the working efficiency of the device.
[0033] like Figure 1 As shown, a feeding hopper 19 is installed at the upper end of the box 1. The feeding hopper 19 is connected to the inside of the box 1, so that the operator can pour refractory powder into the inside of the box 1 through the feeding hopper 19 for screening and sorting.
[0034] like Figure 1 As shown, multiple discharge guide plates 20 are installed on one side of the box body 1. Each discharge guide plate 20 communicates with a chamber inside the box body 1. A baffle 21 is slidably installed on the inner wall of the discharge guide plate 20. The baffle 21 can completely close the part of the discharge guide plate 20 that communicates with the chamber inside the box body 1. Thus, after the refractory powder has been screened and sorted, the operator can open the baffle 21 so that the discharge guide plate 20 opening is no longer closed, so that the refractory powder inside the box body 1 can be taken out.
[0035] The working principle of the multi-stage screening powder sorting device provided by this utility model is as follows: Refractory powder is poured into the box 1 through the feeding hopper 19. The powder falls downward under the action of gravity. Then, the external power component is activated, which drives all the drive discs 14 to rotate. The rotation of the drive discs 14 will drive the rotating shaft 13 and the cam 15 to rotate, so that the cam 15 will intermittently contact the inclined surface of the inclined block 12 with the rotation. This allows the C-shaped mounting frame 5 to slide downward on the fixed plate 2 through the guide action of the sliding rod 9, causing the spring 10 to compress and deform. This causes the C-shaped mounting frame 5 and the screening screen 6 to be generated under the action of the cam 15 and the inclined block 12. The vibration effect allows powder with a particle size smaller than the current aperture of the screen 6 to pass through the screen 6 and enter the next chamber, while powder with a particle size larger than the aperture remains in the current chamber. This multi-stage screening of powder is achieved by using screens 6 with different apertures in different chambers. When it is necessary to replace the screen 6 with a different aperture, the locking plate 16 is released from the bolt connection between the locking plate 16 and the housing 1, and the handle 22 is pulled to remove the locking plate 16 and the locking seat 18 from the housing 1. This allows the locking seat 18 to no longer lock one end of the screen 6, enabling the screen 6 to slide out of the housing 1 from the C-shaped mounting frame 5. This allows for flexible replacement of screens 6 with different apertures.
[0036] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0037] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
