Description

Technical Field

[0001] This utility model belongs to the field of SG abrasive screening, specifically relating to a screening device for SG abrasive production. Background Technology

[0002] SG abrasive, as a high-performance man-made abrasive, is widely used in precision grinding, heavy-duty grinding, and other fields due to its excellent self-sharpening properties, wear resistance, and processing efficiency. In its production process, the sintered blocks, after being crushed, need to undergo strict grading and screening to obtain products with uniform particle size that meet specific specifications.

[0003] Currently, most screening devices used in the industry adopt vibrating screens or rotary screens. Their working principle is as follows: the abrasive to be screened is put into the screen plate (or screen mesh), and through the mechanical movement of vibration or rotation, the abrasive with qualified particle size falls through the screen holes into the collection hopper to become the product, while the large particles of abrasive with excessive particle size are trapped on the screen plate and discharged as the oversize material.

[0004] After screening, large abrasive particles trapped on the screen plate need to be collected manually or by conveying equipment and returned to a separate crushing device for secondary crushing. After crushing, they need to be sent back to the screening device for screening again.

[0005] This operating model not only increases the complexity of the production process and prolongs the overall production cycle, but also reduces production efficiency.

[0006] Therefore, we propose a screening device for SG abrasive production to solve the above problems. Utility Model Content

[0007] To address the issues that this operating mode not only increases the complexity of the production process, extends the overall production cycle, and reduces production efficiency, this utility model provides a screening device for SG abrasive production.

[0008] The solution adopted by this utility model to solve its technical problem is: a screening device for SG abrasive production, including a screen plate, a top cover, a collection hopper, a support frame, a reduction motor, a rotating shaft and a pressure roller. The bottom wall of the screen plate is provided with multiple screen holes, and springs are installed at the four corners of its bottom. The support frame is set below the screen plate, and its four top ends are fixedly connected to the bottom ends of the four springs respectively. The top opening of the hopper is the feed end, and the bottom opening is the discharge end. The hopper is welded and fixed to the bottom of the screen plate, and a vibrating motor is installed on its side. The top cover is located above the sieve plate, and a feed inlet is provided on its top wall. The top cover and the support frame are fixedly connected by multiple connecting frames. The upper end of the rotating shaft is rotatably mounted on the top wall of the upper cover, and its lower end extends into the screen plate and is welded and fixed with an installation arm. One end of the installation arm is mounted with an L-shaped seat, and the pressure roller is set in the L-shaped seat. One end of the roller is rotatably mounted on the vertical section of the L-shaped seat. The geared motor is mounted on the top of the cover, and its output shaft is connected to the upper end of the rotating shaft to drive the rotating shaft to rotate.

[0009] Preferably, a corrugated hose is installed between the bottom of the top cover and the top of the sieve tray.

[0010] Preferably, a fixing sleeve is welded and fixed to the upper section of the rotating shaft, and connecting arms are welded and fixed to both sides of the fixing sleeve, with the bottom end of the connecting arm welded and fixed to the top of the mounting arm.

[0011] Preferably, a scraper is installed at the other end of the mounting arm, and the bottom end of the scraper contacts the inner bottom of the sieve disc.

[0012] Preferably, the support frame includes four columns, and a support rod is welded and fixed between two adjacent columns.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a vibrating motor to drive the screen disc to vibrate, which screens the abrasive material inside the screen disc. At the same time, a reduction motor drives the rotating shaft to rotate, and the scraper moves the abrasive material on the inner edge of the screen disc to the screen hole position. The pressure roller rotates with the rotating shaft to crush and grind the large particles on the inner edge of the screen disc. This allows the large particles of abrasive material to be crushed at the same time as screening. The crushed material can be screened again on the screen disc, thus realizing the integrated operation of screening and crushing, effectively simplifying the production process and improving production efficiency.

[0014] 2. This utility model supports the top cover with multiple connecting frames to ensure the stability of the top cover during use, while not affecting the vibration of the screen plate. The top cover and the screen plate are connected by a corrugated hose, which not only ensures the relative movement space between the two, but also effectively suppresses the dust generated during screening and crushing from escaping, thus improving the working environment.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figure 1-2 This utility model provides a technical solution for a screening device used in the production of SG abrasives: Example 1: according to Figure 1 and Figure 2 As shown, it includes a screen plate 1, a top cover 2, a collection hopper 10, a support frame 7, a reduction motor 41, a rotating shaft 42, and a pressure roller 46. The bottom wall of the screen plate 1 has multiple screen holes 11, and springs 8 are installed at the four corners of its bottom. The support frame 7 is located below the screen plate 1, and its four top ends are fixedly connected to the bottom ends of the four springs 8 respectively.

[0019] The top opening of the hopper 10 is the feed end, and the bottom opening is the discharge end. The hopper 10 is welded and fixed to the bottom of the screen plate 1. A vibration motor 9 is installed on its side. The four springs 8 at the bottom of the screen plate 1 cooperate with the vibration motor 9 to make the screen plate 1 vibrate stably, ensuring that the abrasive with qualified particle size can pass smoothly through the screen hole 11 and enter the hopper 10, thus ensuring the accuracy of screening.

[0020] The upper cover 2 is positioned above the screen plate 1, and a feed inlet 21 is provided on its top wall. A corrugated hose 3 is installed between the bottom of the upper cover 2 and the top of the screen plate 1. By setting the corrugated hose 3, the relative movement space between the upper cover 2 and the screen plate 1 is ensured, and the dust generated during screening and crushing is effectively suppressed from escaping, thus improving the working environment. The upper cover 2 and the support frame 7 are fixedly connected by multiple connecting frames 6. The upper cover 2 is supported by multiple connecting frames 6 to ensure the stability of the upper cover 2 during use, while not affecting the vibration of the screen plate 1.

[0021] The upper end of the rotating shaft 42 is fitted with a bearing 1, which is installed on the top wall of the upper cover 2. Its lower end extends into the screen plate 1 and is welded and fixed with an installation arm 43. One end of the installation arm 43 is fitted with an L-shaped seat 45. The pressure roller 46 is set in the L-shaped seat 45, and one end of its shaft is fitted with a bearing 2. The bearing 2 is installed in the vertical section of the L-shaped seat 45. The pressure roller 46 rotates with the rotating shaft 42 to crush and grind large particles on the inner edge of the screen plate 1, so that the large particles of abrasive can be crushed at the same time as screening. The crushed material can be screened again on the screen plate 1, thus realizing the integrated operation of screening and crushing, effectively simplifying the production process and improving production efficiency.

[0022] A scraper 44 is installed at the other end of the mounting arm 43. The bottom end of the scraper 44 contacts the inner bottom of the screen plate 1. The scraper 44 rotates with the rotating shaft 42 to scrape the abrasive on the inner edge of the screen plate 1 to the position of the screen hole 11.

[0023] The geared motor 41 is mounted on the top of the upper cover 2, and its output shaft is connected to the upper end of the rotating shaft 42 to drive the rotating shaft 42 to rotate.

[0024] In practical use, the SG abrasive production screening device of this utility model first puts the SG abrasive to be screened into the screen plate 1 through the feed port 21, then starts the vibration motor 9 to make the screen plate 1 vibrate stably. Abrasive particles with a particle size smaller than the screen hole 11 in the screen plate 1 quickly pass through the screen hole 11 and fall into the collection hopper 10 below, and are discharged from the discharge end. Start the geared motor 41, which drives the rotating shaft 42 to rotate, causing the mounting arm 43, pressure roller 46 and scraper 44 to rotate together. The rotating pressure roller 46 crushes and breaks down the large abrasive particles in the inner edge area of ​​the screen plate 1 into smaller particles. The scraper 44 rotates with the rotating shaft 42 to scrape the abrasive particles in the inner edge of the screen plate 1 to the position of the screen hole 11, so as to facilitate the rapid screening of the abrasive particles.

[0025] Example 2: Based on Example 1, such as Figure 1 As shown, a fixing sleeve 51 is welded and fixed to the upper section of the rotating shaft 42, and connecting arms 52 are welded and fixed to both sides of the fixing sleeve 51. The bottom end of the connecting arm 52 is welded and fixed to the top of the mounting arm 43. Under the action of the connecting arm 52, the stability of the mounting arm 43 during use is further improved.

[0026] The support frame 7 includes four columns, with a strut welded and fixed between adjacent columns.
