Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, specifically a screen box with dustproof function. Background Technology

[0002] In mining, metallurgy, chemical, building materials, and food industries, particle size classification is often used to separate granular materials such as ores, sand, coal powder, and grains into finished or semi-finished products of different specifications, as well as to remove dust. Screen boxes are often used for screening. However, the dust generated during the screening process can enter the human body through the respiratory tract. Long-term exposure can easily lead to occupational diseases such as pneumoconiosis and asthma, threatening the health of operators. Dust removal functions are needed to improve the overall practicality of the screen box and avoid environmental pollution. Therefore, a screen box with dust prevention function is proposed.

[0003] Chinese Utility Model Patent Publication No. CN222469678U discloses a dustproof sieve box. This dustproof sieve box, equipped with a screening section, uses a motor to drive spiral blades and a rotating screen frame to rotate inside the sieve box body. The rotating spiral blades move sand and gravel within the sieve box body, and the rotating screen frame is simultaneously driven by the drive gears. During rotation, the screen frame, with its internal mesh, performs a screening operation on the sand and gravel. However, while this dustproof sieve box can screen sand and gravel through the mesh, it is not convenient for guiding and collecting dust inside, leading to dust accumulation inside the sieve box. This results in poor practicality and hinders its widespread use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a sieve box with dustproof function, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is as follows: a screen box with dustproof function, including a screen box body, a vibrating motor and a collection box. A connecting box and an air inlet box are fixedly installed from bottom to top at the end of the screen box away from the vibrating motor. A protective box and a feed hopper are fixedly installed at the other end of the air inlet box away from the screen box body. A dustproof plate is fixedly installed on one side of the protective box, and a drive motor is fixedly installed on one side of the protective box. A rotating column and a rotating cylinder are fixedly installed at the output end of the drive motor. A guide frame separating the protective box and the feed hopper is fixedly installed inside the air inlet box. An inclined baffle is fixedly installed inside the rotating cylinder away from the protective box and located in the connecting box. A dust collection box is slidably connected inside the collection box.

[0006] Preferably, at the end of the screen box away from the vibrating motor, screen plate one and screen plate two are arranged sequentially from top to bottom, and at the other end of the screen box away from the vibrating motor and located at the outer edge of the screen box, an installation corner and a buffer are fixedly installed.

[0007] Through the above technical solution, by combining the design of sieve plate one and sieve plate two with the design of the vibration motor, the material can be initially screened through sieve plate one during use. Then, the material from sieve plate one falls to the top of sieve plate two for secondary screening, thereby improving the screening efficiency.

[0008] Preferably, the vibrating motor is fixedly installed with a mounting bracket that is fixedly installed with the connecting box at one end near the screen box, and the feed hopper is fixedly installed with an inclined feeding plate at one end near the screen box and inside the protective box.

[0009] The above technical solution, through the design of the mounting bracket, can fix the drive motor, and the design of the feeding plate can guide the material, which can facilitate subsequent dust removal.

[0010] Preferably, the collection box and the connecting box are interconnected, and a protective net is fixedly installed at the connection between the collection box and the connecting box.

[0011] Through the above technical solution, the collection box and the connecting box are interconnected, allowing the airflow in the connecting box to carry dust into the collection box, thus achieving the dust prevention function. The protective net can not only block fine materials that may leak out during the screening process from entering the dust collection path, avoiding material blockage and affecting dust removal efficiency, but also ensure that the airflow carries dust through.

[0012] Preferably, the dust collection box is adapted to the collection box, and the outer side of the dust collection box is threaded with a positioning bolt that penetrates into the interior of the dust collection box.

[0013] Through the above technical solution, the dust collection box and the collection box are matched to ensure a tight seal and prevent dust from escaping from the gaps, thus enhancing the dustproof effect. The positioning bolt is fixed by threads, which allows for quick disassembly and assembly of the dust collection box, facilitating regular cleaning of the accumulated dust. At the same time, it prevents the dust collection box from shifting or falling off due to vibration during equipment operation, ensuring the stability and reliability of the dustproof system.

[0014] Preferably, a second baffle is fixedly installed inside the collection box, and the second baffle has an inclined cross-section.

[0015] Through the above technical solution, the inclined baffle can change the airflow direction, so that the airflow carrying dust forms a buffer in the collection box, and the dust is separated from the airflow by gravity, so that the dust slides down the inclined surface of the baffle into the dust collection box, which makes it easier to collect the dust.

[0016] Preferably, the protective net and the second baffle are located on the same horizontal line, and the second baffle is located at the top of the dust collection box.

[0017] With the above technical solution, the protective net and the second baffle are horizontally aligned, so that the dust entering the collection box from the connecting box is filtered by the protective net and falls directly onto the inclined surface of the second baffle, sliding down to the dust collection box through the shortest path, avoiding the dust from forming eddies or being stirred up again in the collection box. The second baffle covers the top of the dust collection box, which can guide the dust to fall accurately into the box, making it easy to clean later.

[0018] Compared with the prior art, the present invention provides a sieve box with dustproof function, which has the following beneficial effects:

[0019] 1. This dustproof screen box utilizes the inclined structure of the second baffle to achieve efficient separation of dust and airflow through airflow buffering and gravity, reducing dust residue in the equipment. Combined with the design of the rotating drum and the first baffle, it can achieve airflow agitation, forming positive air pressure at the feed end to prevent dust from overflowing. At the same time, the airflow circulation can guide the dust into the dust collection box, which can facilitate subsequent quick cleaning.

[0020] 2. This dustproof screen box features a quick-release mechanism for the dust collection box via positioning bolts. When the dust collection box needs cleaning, the positioning bolts can be removed, and the dust collection box can be pulled out for easy cleaning of dust. The protective net prevents materials from clogging the dust inlet channel, and the dustproof plate and sealed dust collection box prevent dust leakage, thus improving its practicality.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: As Figure 1-7 As shown, the present invention provides a dustproof screen box, comprising a screen box body 1, a vibrating motor 2, and a collection box 19. A connecting box 7 and an air inlet box 8 are fixedly installed sequentially from bottom to top at one end of the screen box body 1 away from the vibrating motor 2. A protective box 9 and a feed hopper 17 are fixedly installed at the other end of the air inlet box 8 away from the screen box body 1. A dustproof plate 10 is fixedly installed on one side of the protective box 9, and a drive motor 12 is fixedly installed on one side of the protective box 9. A rotating column 13 and a rotating cylinder 14 are fixedly installed at the output end of the drive motor 12. A guide frame 16 separating the protective box 9 and the feed hopper 17 is fixedly installed inside the air inlet box 8. An inclined baffle 15 is fixedly installed inside the rotating cylinder 14, away from the protective box 9 and located within the connecting box 7. A dust collection box 22 is slidably connected inside the collection box 19.

[0031] Specifically, at the end of the screen box 1 away from the vibrating motor 2, screen plate 3 and screen plate 4 are arranged sequentially from top to bottom. At the end of the screen box 1 away from the vibrating motor 2 and located at the outer edge of the screen box 1, mounting angle 5 and buffer 6 are fixedly installed. The advantage is that, through the design of screen plate 3 and screen plate 4 in conjunction with the design of the vibrating motor 2, the material can be initially screened through screen plate 3 during use. Then, the material on screen plate 3 falls to the top of screen plate 4, where it can be screened a second time, thus improving the screening efficiency.

[0032] Specifically, the vibrating motor 2 is fixedly installed with a mounting bracket 11 that is fixedly installed with the connecting box 7 at one end near the screen box 1. The feed hopper 17 is fixedly installed with an inclined feeding plate 18 at one end near the screen box 1 and inside the protective box 9. The advantage is that the mounting bracket 11 can fix the drive motor 12, and the feeding plate 18 can guide the material, which is convenient for subsequent dust removal.

[0033] Specifically, the collection box 19 and the connecting box 7 are interconnected, and a protective net 20 is fixedly installed at the connection between the collection box 19 and the connecting box 7. The advantage is that the interconnection between the collection box 19 and the connecting box 7 allows the airflow in the connecting box 7 to carry dust into the collection box 19, thus achieving the dust prevention function. The protective net 20 can not only block the fine materials that may leak out during the screening process from entering the dust collection path, avoiding material blockage and affecting the dust removal efficiency, but also ensure that the airflow carries dust through.

[0034] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0035] Specifically, the dust collection box 22 is adapted to the collection box 19. The outer side of the dust collection box 22 is threaded with a positioning bolt 23 that extends into the interior of the dust collection box 22. The advantage is that the dust collection box 22 and the collection box 19 are adapted to ensure a tight seal, preventing dust from escaping from gaps and enhancing the dustproof effect. The positioning bolt 23 is fixed by threads, allowing for quick disassembly and assembly of the dust collection box 22, facilitating regular cleaning of accumulated dust. At the same time, it prevents the dust collection box 22 from shifting or falling off due to vibration during equipment operation, ensuring the stability and reliability of the dustproof system.

[0036] Specifically, a baffle 21 is fixedly installed inside the collection box 19. The baffle 21 has an inclined cross-section. The advantage is that the inclined baffle 21 can change the airflow direction, so that the airflow carrying dust forms a buffer in the collection box 19. The dust is separated from the airflow by gravity, so that the dust slides down the inclined surface of the baffle 21 into the dust collection box 22, which makes it easy to collect the dust.

[0037] Specifically, the protective net 20 and the second baffle 21 are on the same horizontal line. The second baffle 21 is located on the top of the dust collection box 22. The advantage is that the protective net 20 and the second baffle 21 are horizontally aligned, so that the dust entering the collection box 19 from the connecting box 7 is filtered by the protective net 20 and falls directly onto the inclined surface of the second baffle 21, sliding down to the dust collection box 22 through the shortest path. This avoids the dust forming a vortex or being stirred up again in the collection box 19. The second baffle 21 covers the top of the dust collection box 22, which can guide the dust to fall accurately into the box, making it easier for subsequent cleaning.

[0038] Working principle: During use, the material enters the protective box 9 through the feed hopper 17, is guided to the air inlet box 8 by the inclined discharge plate 18, and falls to the top of the screen box 1 after being separated by the guide frame 16. The vibrating motor 2 drives the screen box 1 to vibrate. The material is first screened by the upper screen plate 3, and the undersize material falls to the lower screen plate 4 for secondary screening. Finally, the qualified material is discharged from the end of the screen box 1, and the oversize material is collected from the end of the screen plate. The drive motor 12 drives the rotating column 13 and the rotating cylinder 14 to rotate. The inclined baffle 15 on the rotating cylinder 14 agitates the air in the connecting box 7, forming an upward airflow, preventing the dust generated during the screening process from escaping from the feed end, and at the same time introducing the dust into the connecting box 7. The dust-laden airflow passes through the connecting box 7 and the collection box 19. The material enters the collection box 19 through the inlet. The protective net 20 blocks material particles from entering, allowing only airflow and dust to pass through. The airflow changes direction after hitting the inclined baffle 21. The dust slides down the baffle 21 to the dust collection box 22 due to gravity. The dust collection box 22 is fixed inside the collection box 19 by the positioning bolt 23. The positioning bolt 23 can be removed periodically to remove the dust collection box 22 for cleaning, ensuring the dust prevention system remains effective. The screen box 1 is fixed by the mounting angle 5 and the buffer 6. The buffer 6 absorbs vibration energy, reduces the overall shaking of the equipment, and ensures the stability of screening. The dustproof plate 10 seals the side of the protective box 9, forming a closed feeding channel with the guide frame 16 and the discharge plate 18 to prevent dust from overflowing. The dust collection box 22 is fitted and sealed with the collection box 19 to prevent dust leakage.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
