Description

Technical Field

[0001] This utility model relates to the field of screening technology, and in particular to a particle size screening device for aluminum-iron alloys. Background Technology

[0002] Aluminum-iron alloy particles need to be screened to select particles of the required size in order to meet the usage requirements. Screening requires the use of a screening device.

[0003] A search revealed a prior art multi-stage particle size screening device (publication number: CN101653761B), comprising a motor, a transmission mechanism, a support, a drum frame, a screen, a feed hopper, and a recovery hopper. The motor drives the transmission mechanism to rotate the drum screen composed of the drum frame and the screen. The drum screen has a feed inlet and a recovery outlet at both ends for material input and output. The feed inlet is connected to the feed hopper, and the recovery outlet is connected to the recovery hopper. The drum screen is pivotally connected to the support at an incline, with the feed inlet higher than the recovery outlet. The drum frame has at least two drum frame layers arranged radially. Each drum frame layer is covered with a screen, which has several screen segments with different apertures. A discharge hopper is also provided directly below each screen segment. The aperture of the screen segments on the same drum frame layer gradually increases from the feed inlet to the recovery outlet along the direction of the drum frame, and the corresponding screen segments on the drum frame layer gradually decrease from the inside to the outside along the radial direction of the drum frame.

[0004] In the existing technology, materials are screened by opening multiple screen holes of different diameters on a drum. However, during the screening process, the materials flow radially along the screen cylinder, which makes it easy for the materials to mix after sorting. In addition, the setting of multiple inner and outer screen cylinders makes the drive unit relatively complex, and the whole machine is large in size and has high operating and maintenance costs.

[0005] Therefore, we propose an aluminum-iron alloy particle size screening device. Utility Model Content

[0006] The present invention mainly addresses the technical problem of material contamination after screening, and provides an aluminum-iron alloy particle size screening device.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an aluminum-iron alloy particle size screening device, comprising:

[0008] The box body has a feeding hopper for feeding materials fixedly installed on its top;

[0009] A screening module is set inside a box and has several sets. The screening module includes a screen plate, a vibrating motor and a guide chute. The screen plate is elastically set inside the box, the vibrating motor is fixedly installed at the bottom of the screen plate, and the guide chute is fixedly installed on one side of the box.

[0010] The connecting assembly, located inside the housing, is used to install the sieve plate.

[0011] In a preferred embodiment of this utility model, the sieve plate is inclinedly arranged inside the box, and the bottom of the sieve plate is evenly provided with sieve holes, with the diameter of the sieve holes of multiple sieve plates decreasing evenly.

[0012] In a preferred embodiment of this utility model, the side wall of the box is provided with a window for discharging materials, and the sieve plate is fixedly installed inside the window.

[0013] In a preferred embodiment of this utility model, the connecting assembly includes a guide rod, an adjusting nut, and a spring. Two guide rods are fixedly installed at the bottom of the housing, the screen plate is slidably mounted on the guide rods, the adjusting nut is threadedly connected to the guide rods, and a spring for supporting the screen plate is installed above the adjusting nut.

[0014] In a preferred embodiment of this utility model, the guide rod is formed into a cylinder, with two guide rods distributed diagonally along the box body, and each sieve plate has holes adapted to the guide rods.

[0015] In a preferred embodiment of this utility model, the spring is sleeved on the guide rod, and the lower end of the spring abuts against the upper end of the adjusting nut.

[0017] This invention provides a particle size screening device for aluminum-iron alloys. It has the following beneficial effects:

[0018] 1. This aluminum-iron alloy particle size screening device uses three screen plates to perform gradient screening of aluminum-iron alloy particles fed into the hopper. Particles smaller than the corresponding screen holes are discharged from the corresponding guide chute. A vibrating motor causes the elastically connected screen plates to vibrate, promoting screening and encouraging particles to roll off the screen plates and onto the guide chute for discharge. This results in high screening efficiency, good performance, and minimal clogging. The device can operate continuously, effectively improving production efficiency. It boasts advantages such as high screening accuracy, large processing capacity, compact structure, and simple operation and maintenance. It eliminates the need for complex drive structures, allowing particles of different sizes to be discharged to different locations for fine screening and storage.

[0019] 2. This aluminum-iron alloy particle size screening device uses multiple sets of adjusting nuts and springs on the guide rods. The adjusting nuts and springs on two guide rods support the screen plate, allowing the screen plate to move vertically. Combined with a vibrating motor, the vibration of the screen plate improves the screening and discharge effect. As an optimized solution, an adjusting nut can be set at the top and bottom of the screen plate. By adjusting the position of the adjusting nut, the spring is compressed, thereby adjusting the supporting force provided by the spring to the screen plate. This makes the amplitude and frequency of the screen plate adjustable, resulting in more controllable screening.

[0020] 3. This aluminum-iron alloy particle size screening device introduces the fine particles screened by the bottom screen plate into the discharge port through two discharge ports and discharges them out of the box. A container can be set at the bottom of the box to load the finest particles. With the help of multiple guide troughs, the particles screened by the corresponding screen plates are guided to achieve the sorting and collection of particles of different sizes.

[0027] An aluminum-iron alloy particle size screening device, such as Figure 1 and Figure 2 As shown, it includes:

[0028] The box body 10 has a feeding hopper 11 fixedly installed on its top for feeding materials;

[0029] like Figure 2 , Figure 3 and Figure 4As shown, a screening module is set inside a housing 10 and has several sets. The screening module includes a screen plate 20, a vibrating motor 21, and a guide chute 22. The screen plate 20 is elastically set inside the housing 10. The vibrating motor 21 is fixedly installed at the bottom of the screen plate 20. The guide chute 22 is fixedly installed on one side of the housing 10. The screen plate 20 is inclined inside the housing 10. Screen holes are evenly opened at the bottom of the screen plate 20. The diameter of the screen holes of multiple screen plates 20 decreases evenly. A window for material discharge is opened on the side wall of the housing 10. The screen plate 20 is fixedly installed in the window.

[0030] In this scheme, at least three screen plates 20 are set inside the box 10. The screen plate 20 at the top has the largest screen hole diameter, the screen plate 20 at the bottom has the smallest screen hole diameter, and the screen plate 20 in the middle has a screen hole diameter in between. The aluminum-iron alloy particles fed into the feed hopper 11 are graded through the three screen plates 20. Particles smaller than the corresponding screen hole diameter of the screen plate 20 are discharged from the corresponding guide chute 22. The vibrating motor 21 can make the elastically connected screen plates 20 vibrate, which can promote screening on the one hand and promote the particles to roll off the screen plates 20 and be discharged from the guide chute 22 on the other hand. The screening efficiency is high, the effect is good, and it is not easy to clog.

[0031] like Figure 3 and Figure 5 As shown, the connecting assembly is installed inside the housing 10 for mounting the sieve plate 20;

[0032] The connecting assembly includes guide rods 30, adjusting nuts 31, and springs 32. Two guide rods 30 are fixedly installed at the bottom of the housing 10. The screen plate 20 is slidably mounted on the guide rods 30. The adjusting nut 31 is threadedly connected to the guide rods 30. A spring 32 for supporting the screen plate 20 is installed above the adjusting nut 31. The guide rods 30 form cylinders. The two guide rods 30 are distributed diagonally along the housing 10. Each screen plate 20 has a hole adapted to the guide rods 30. The spring 32 is sleeved on the guide rods 30. The lower end of the spring 32 abuts against the upper end of the adjusting nut 31.

[0033] In this scheme, in order to achieve elastic connection of multiple screen plates 20, multiple sets of adjusting nuts 31 and springs 32 are set on the guide rods 30. The adjusting nuts 31 and springs 32 on the two guide rods 30 support the screen plates 20, so that the screen plates 20 can be displaced in the vertical direction. In conjunction with the vibration motor 21, the vibration of the screen plates 20 can improve the screening and discharge effect. As an optimized solution, an adjusting nut 31 can be set at the top and bottom of the screen plates 20. By adjusting the position of the adjusting nut 31, the spring 32 is compressed, thereby adjusting the supporting force provided by the spring 32 to the screen plates 20. This makes the amplitude and frequency of the screen plates 20 adjustable, and the screening of the screen plates 20 more controllable.

[0034] like Figure 4As shown, a discharge port 13 is provided at the center of the bottom of the box 10. Two guide plates 12 are fixedly installed at the bottom of the box 10. The top of the two guide plates 12 forms a slope that faces the discharge port 13. Fine particles screened by the bottom screen plate 20 are introduced into the discharge port 13 and discharged from the box 10 through the two discharge ports 13. A container can be set at the bottom of the box 10 to load the finest particles. With the help of multiple guide troughs 22, the particles screened by the corresponding screen plates 20 are guided to achieve the sorting and collection of particles of different sizes.

[0035] The working principle of this utility model is as follows: At least three screen plates 20 are installed inside the housing 10. The uppermost screen plate 20 has the largest screen hole diameter, the lowermost screen plate 20 has the smallest screen hole diameter, and the middle screen plate 20 has screen holes in between. The aluminum-iron alloy particles fed into the hopper 11 are graded through these three screen plates 20. Particles smaller than the corresponding screen hole diameter are discharged from the corresponding guide chute 22. The vibrating motor 21 causes the elastically connected screen plates 20 to vibrate, which promotes screening and also facilitates the particles rolling off the screen plates 20 and onto the guide chute 22 for discharge. Multiple sets of adjusting nuts 31 and springs 32 are installed on the guide rods 30, and the adjusting nuts on the two guide rods 30... The screen plate 20 is supported by spring 31 and spring 32, allowing it to move vertically. Combined with the vibration motor 21, the vibration of the screen plate 20 improves screening and discharge efficiency. As an optimized solution, an adjusting nut 31 can be installed above and below the screen plate 20. By adjusting the position of the adjusting nut 31, the spring 32 is compressed, allowing the amplitude and frequency of the screen plate 20 to be adjusted. Fine particles screened by the lowest screen plate 20 are guided into the discharge port 13 through two discharge ports 13 and discharged from the housing 10. A container can be installed below the housing 10 to hold the smallest particles. Multiple guide troughs 22 guide the particles screened by the corresponding screen plates 20, achieving the sorting and collection of particles of different sizes.
