Description

Technical Field

[0001] This utility model relates to the field of barite processing, and in particular to a feeding device for barite powder grinding. Background Technology

[0002] In the barite processing industry, barite powder has extremely wide applications, covering many fields such as oil drilling, chemicals, rubber, and coatings. Due to the stringent quality requirements of various fields for barite powder, indicators such as particle size, purity, and uniformity must be precisely controlled, making the feeding process in the barite powder grinding process crucial.

[0003] Currently, the feeding device used for barite powder grinding, as a key component connecting the raw materials and the grinding mill, suffers from numerous problems. Existing devices struggle to achieve uniform feeding, frequently resulting in feeding gaps during actual operation. This leads to discontinuous operation of the grinding mill and uneven particle size of the produced barite powder. Furthermore, material jamming also occurs frequently. This not only severely impacts grinding efficiency but also increases the wear and tear on critical components such as the motor due to frequent start-ups and shutdowns, raising equipment maintenance costs and hindering the efficient and stable operation of the entire barite processing flow. Utility Model Content

[0004] To overcome the shortcomings of existing devices that cannot uniformly feed materials, the technical problem to be solved is to provide a feeding device for grinding barite powder that can uniformly feed materials.

[0005] The technical solution of this utility model is: a feeding device for grinding barite powder, including a feeding box, a baffle cover fixedly connected to the bottom of the feeding box, a motor A fixedly connected to the lower part of the feeding box, a grinding rod for grinding barite fixedly connected to the output end of the motor A, a grinding wall fixedly connected to the upper part of the feeding box, a feed inlet fixedly connected to the top of the feeding box, a motor B fixedly connected to the upper part of the feeding box, a small gear fixedly connected to the output end of the motor B, a large gear rotatably connected to the upper part of the feeding box, the small gear meshing with the large gear, and a material spreading body fixedly connected to the large gear. The material spreading body is spiral-shaped and used for uniform feeding.

[0006] In one embodiment, the device further includes a stirring rod, which is fixedly connected to the bottom edge of the large gear to prevent material jamming. A scraper for uniformly scraping material is slidably connected to the stirring rod. A limit block is fixedly connected to the stirring rod, and a stop block is fixedly connected to the stirring rod. A spring is sleeved on the stirring rod, with one end of the spring fixedly connected to the limit block and the other end of the spring fixedly connected to the scraper.

[0007] In one embodiment, a reflective strip is also included, with the feed box having a reflective strip fixedly connected to it for nighttime visibility.

[0008] In one embodiment, a protective cover is also included, which is fixedly connected to the feed box to protect the motor B.

[0009] In one embodiment, a protective cover is also included, which is fixedly connected to the feed box to protect the motor A.

[0010] In one embodiment, a warning light is also included, which is fixedly connected to the feeding box to indicate the working status.

[0011] The beneficial effects are: 1. By driving the small gear through motor B, the large gear is driven to rotate, causing the spiral spreading body to rotate, which will evenly disperse the barite poured from the feed port. The barite flows along a specific path to the grinding rod, and motor A drives the grinding rod to work with the grinding wall to grind, effectively achieving uniform spreading and reducing the phenomenon of working gaps.

[0012] 2. The large gear drives the stirring rod to rotate, loosening the material at the bottom. When the material is unevenly piled up, the scraper rotates with the stirring rod to scrape the material. When there is too much material, the scraper is squeezed and the spring contracts to buffer. After the accumulation is relieved, the spring pushes the scraper back. The cooperation of all parts effectively prevents material jamming and helps to achieve uniform material feeding.

[0013] 3. By reflecting light through reflective strips, the location of the device is indicated, effectively preventing safety accidents such as collisions in low light conditions and serving as a reminder to staff. Attached Figure Description

Detailed Implementation

[0018] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] Example: A feeding device for grinding barite powder, such as... Figure 1-3As shown, the device includes a feeding box 1, a baffle cover 101, a motor A2, a grinding rod 3, a grinding wall 301, a feed inlet 4, a motor B5, a pinion 6, a gear 7, and a feed spreader 8. The baffle cover 101 is fixedly connected to the bottom of the feeding box 1. The motor A2 is fixedly connected to the lower part of the feeding box 1. The grinding rod 3 for grinding barite is fixedly connected to the output end of the motor A2. The grinding wall 301 is fixedly connected to the top of the feeding box 1. The feed inlet 4 is fixedly connected to the top of the feeding box 1. The motor B5 is fixedly connected to the top of the feeding box 1. The pinion 6 is fixedly connected to the output end of the motor B5. The gear 7 is rotatably connected to the upper part of the feeding box 1. The pinion 6 meshes with the gear 7. The feed spreader 8 is fixedly connected to the gear 7. The feed spreader 8 is spiral-shaped and used for uniform feeding.

[0020] After the device is started, the motor B5 drives the pinion 6 to rotate, and the pinion 6 drives the large gear 7 meshing with it to rotate, which in turn drives the spiral-shaped material spreader 8 fixed on the large gear 7 to rotate. At this time, barite is poured in from the feed port 4. The spiral-shaped material spreader 8, with its unique spiral structure, continuously and evenly disperses the barite in all directions during rotation. Under the action of gravity, the barite flows down to the grinding rod 3 along a specific guide path inside the feed box 1. The motor A2 drives the grinding rod 3 to rotate at high speed. When the barite passes through the gap between the grinding rod 3 and the grinding wall 301, the grinding rod 3 and the grinding wall 301 work together to grind the barite, effectively achieving uniform material spreading and greatly reducing the phenomenon of working gaps.

[0021] like Figure 1-3 As shown, it also includes a stirring rod 9, a scraper 10, a limiting block 11, a stop block 12, and a spring 13. The stirring rod 9, which prevents material jamming, is fixedly connected to the bottom edge of the large gear 7. The scraper 10, which is used to scrape material evenly, is slidably connected to the stirring rod 9. The limiting block 11 is fixedly connected to the stirring rod 9. The stop block 12 is fixedly connected to the stirring rod 9. The spring 13 is sleeved on the stirring rod 9. One end of the spring 13 is fixedly connected to the limiting block 11, and the other end of the spring 13 is fixedly connected to the scraper 10.

[0022] When the grinding rod 3 grinds the barite, the large gear 7 rotates, driving the stirring rod 9, which is fixed at the bottom edge, to rotate synchronously. The stirring rod 9 continuously stirs the barite at the bottom, effectively loosening any potentially accumulated material and preventing clumping. When the material accumulates unevenly at the bottom, the scraper 10, which is slidably connected to the stirring rod 9, comes into play. As the stirring rod 9 rotates, the scraper 10 scrapes and smooths the accumulated barite, making it more even. When a large amount of material accumulates below and is about to exceed the height of the scraper 10, the barite exerts an upward squeezing force on the scraper 10. The scraper 10 slides upward along the stirring rod 9. During this process, the spring 13, which is sleeved on the stirring rod 9, is compressed and contracts. The contraction of the spring 13 acts as a buffer, preventing the scraper 10 from being damaged due to excessive instantaneous force. Once the barite accumulation is relieved, the spring 13, with its own elastic restoring force, pushes the scraper 10 back to its initial lower position to continue scraping, effectively preventing barite from getting stuck and further assisting in achieving uniform material feeding.

[0023] like Figure 1 As shown, it also includes a reflective strip 14, which is fixedly connected to the feeding box 1 for nighttime warning.

[0024] In a nighttime working environment, when the workshop lighting or other light sources shine on the reflective strip 14 on the unloading box 1, the reflective strip 14 uses its special reflective material to reflect the light back in a directional manner. The reflected light can attract the attention of the surrounding staff, enabling them to clearly identify the location of the device, effectively avoiding safety accidents such as collisions in low light conditions, and truly playing the role of reminding the staff.

[0025] like Figure 1 and Figure 2 As shown, it also includes a protective cover 15, which is fixedly connected to the feed box 1 for protecting the motor B5.

[0026] The protective cover 15 is tightly fixed to the position of the feed box 1 corresponding to the motor B5. During device operation, the protective cover 15 completely covers the motor B5, effectively blocking external dust, debris, and possible accidental collisions. The entry of dust and debris may cause internal short circuits, wear, and other malfunctions in the motor B5, while accidental collisions may damage the outer casing and internal precision components of the motor B5. The protection provided by the protective cover 15 greatly reduces the risk of external damage to the motor B5 and significantly increases its service life.

[0027] like Figure 2 As shown, it also includes a protective cover 16, which is fixedly connected to the feed box 1 to protect the motor A2.

[0028] The protective cover 16 is securely installed on the feed box 1 at the position corresponding to the motor A2. During the long-term operation of the motor A2, barite powder may fly around. The protective cover 16 can effectively block the flying barite powder from entering the motor A2, preventing the barite powder from accumulating between the rotating parts of the motor A2, avoiding the motor A2 from getting stuck and unable to operate normally due to powder accumulation, thereby ensuring that the device can work stably for a long time and reducing downtime maintenance time caused by motor A2 failure.

[0029] like Figure 1 As shown, it also includes a warning light 17, which is fixedly connected to the feeding box 1 to indicate the working status.

[0030] The warning light 17 is connected to the device's control system via a circuit connection. When the device is in normal operation, the control system sends a signal to the warning light 17. When an abnormal situation occurs, such as motor overload or material blockage, the control system detects the corresponding fault signal and immediately sends different instructions to the warning light 17. The warning light 17 then changes its display status, intuitively reflecting the current working status of the device to the operator, greatly improving the device's practicality and facilitating timely response by the operator.

[0031] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
