Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a ball mill feeding device. Background Technology

[0002] The main function of the feeding device of a ball mill is to transport the slurry to be ground into the ball mill. With the continuous improvement of industrial production requirements for grinding precision, production continuity and environmental protection, the structural design of traditional feeding devices has gradually become unable to meet the needs of modern production. Especially in the case of large flow slurry transportation, the sealing performance, feeding stability and installation and maintenance convenience of the feeding device have become key factors affecting the efficiency of the entire production line.

[0003] Traditional ball mill feeding devices on the market usually use flanges with single-layer rubber sealing rings for direct connection. In actual use, the slurry is prone to leakage from the connection gap during transportation, which not only wastes raw materials, but also corrodes the surrounding parts of the equipment, increases cleaning and maintenance costs, and poses an environmental pollution risk.

[0004] Therefore, to address the shortcomings of existing traditional ball mill feeding devices on the market, a new ball mill feeding device can be designed. This device features a leak-proof extension pipe with its outer wall fitting snugly against the inner wall of the receiving pipe. An embedded annular groove and a leak-proof felt sleeve are installed at the outer end of the leak-proof extension pipe to enhance the sealing effect. Simultaneously, a multi-layered sealing structure, consisting of a limiting ring and two sets of semi-circular sealing pressure rings, effectively prevents molten slurry leakage, thus facilitating the solution of the aforementioned problems. Utility Model Content

[0005] To overcome the shortcomings of traditional ball mill feeding devices on the market, which typically use flanges with single-layer rubber sealing rings for direct connection, the slurry is prone to leakage from the connection gap during transportation, resulting in material waste, this utility model provides a ball mill feeding device.

[0006] The technical solution is as follows: A ball mill feeding device includes a feed pipe, a leak-proof extension pipe, a limiting ring, a semi-circular sealing ring, a ball mill body, and a receiving pipe; the feed pipe has a feed chamber for conveying slurry inside, and a ball mill body for grinding is matched on one side of the feed pipe. A receiving pipe corresponding to the feed pipe is provided on the side of the ball mill body near the feed pipe. A leak-proof extension pipe extending into the receiving pipe is provided at one end of the feed pipe near the receiving pipe. The outer wall of the leak-proof extension pipe is fitted with the inner wall of the receiving pipe. A limiting ring corresponding to the receiving pipe is provided at the outer edge of the feed pipe near the leak-proof extension pipe. Two sets of semi-circular sealing rings are provided between the limiting ring and the outer end of the receiving pipe. The two sets of semi-circular sealing rings are symmetrically arranged along the outer end of the connection between the limiting ring and the receiving pipe.

[0007] Furthermore, the feed chamber is equipped with a push screw, and a transmission hole is opened at the center of the rear end of the feed chamber. The rear end of the feed pipe is equipped with a drive motor corresponding to the push screw. The output shaft of the drive motor passes through the transmission hole and is connected to the push screw. The outer end of the drive motor is fitted with a motor cover, and the rear end of the feed pipe is equipped with a mounting ring seat for mounting the motor cover.

[0008] Furthermore, the upper part of the feed pipe is provided with a feed port that communicates with the feed chamber, and the upper end of the feed port is matched with a feed hopper that connects to the feed port.

[0009] Furthermore, the outer end of the leak-proof extension pipe is provided with an embedded annular groove, and a leak-proof felt sleeve is fitted inside the embedded annular groove.

[0010] Furthermore, a first sealing ring groove is provided at the outer end of the limiting ring, and a second sealing ring groove corresponding to the first sealing ring groove is provided at the edge of the receiving pipe near the outer end of the limiting ring.

[0011] Furthermore, two sets of semi-circular sealing strips are symmetrically provided on the adjacent sides of the two sets of semi-circular sealing rings. The two sets of semi-circular sealing strips correspond to the first sealing ring groove and the second sealing ring groove, respectively. A rubber sealing strip is attached between the two sets of semi-circular sealing strips.

[0012] Furthermore, both ends of the two sets of semi-circular sealing rings are provided with connecting blocks, and the surfaces of the connecting blocks are symmetrically provided with two sets of connecting holes.

[0013] The beneficial effects are as follows: Compared to the shortcomings of traditional ball mill body feeding devices currently on the market, this application, through its multi-seal structure design of a leak-proof extension pipe, a leak-proof felt sleeve, and a semi-circular sealing pressure ring, effectively prevents slurry leakage from the connection points during transportation. This not only avoids raw material waste and reduces production costs but also reduces slurry corrosion of surrounding equipment components, lowers cleaning and maintenance costs, and reduces environmental pollution risks. The propulsion screw, driven by the drive motor, rotates, enabling more stable and uniform slurry delivery into the ball mill body. This avoids the uneven slurry delivery problems that may occur in traditional feeding methods, ensuring uniform slurry distribution within the ball mill body and thus improving grinding efficiency. The motor cover, located outside the drive motor, effectively prevents the drive motor from being affected by external environmental factors such as dust and moisture, reducing the failure rate of the drive motor, extending its service life, and lowering equipment maintenance and replacement costs.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] Example

[0022] like Figures 1-5 As shown, a ball mill feeding device includes a feed pipe 1, a leak-proof extension pipe 2, a limiting ring 3, a semi-circular sealing pressure ring 4, a ball mill body 5, and a receiving pipe 6. The feed pipe 1 has a feed chamber 101 for conveying slurry. The ball mill body 5, which plays a grinding role, is matched to one side of the feed pipe 1. The receiving pipe 6 corresponding to the feed pipe 1 is provided on the side of the ball mill body 5 near the feed pipe 1. The leak-proof extension pipe 2 extending into the receiving pipe 6 is provided at one end of the feed pipe 1 near the receiving pipe 6. The outer wall of the leak-proof extension pipe 2 is attached to the inner wall of the receiving pipe 6. The limiting ring 3 corresponding to the receiving pipe 6 is provided at the outer edge of the feed pipe 1 near the leak-proof extension pipe 2. Two sets of semi-circular sealing pressure rings 4 are provided between the limiting ring 3 and the outer end of the receiving pipe 6. The two sets of semi-circular sealing pressure rings 4 are symmetrically arranged along the outer end of the connection between the limiting ring 3 and the receiving pipe 6.

[0023] The feed chamber 101 is equipped with a push screw 102. A transmission hole 103 is opened at the center of the rear end of the feed chamber 101. The rear end of the feed pipe 1 is equipped with a drive motor 106 (model YE3-132S1-2) corresponding to the push screw 102. The output shaft of the drive motor 106 passes through the transmission hole 103 and is connected to the push screw 102. The outer end of the drive motor 106 is fitted with a motor cover 107. The rear end of the feed pipe 1 is equipped with a mounting ring seat 105 for mounting the motor cover 107. The push screw 102 can rotate under the drive of the drive motor 106, which can more stably and evenly transport the slurry into the ball mill body 5, avoiding uneven slurry delivery that affects the grinding effect. The motor cover 107 can protect the drive motor 106 from the influence of the external environment and extend the service life of the drive motor 106. The mounting ring seat 105 facilitates the installation and fixation of the motor cover 107.

[0024] The upper part of the feed pipe 1 is provided with a feed port 104 that connects to the feed chamber 101. The upper end of the feed port 104 is matched with a feed hopper 7 that connects to the feed port 104. The feed hopper 7 facilitates the addition of slurry into the feed chamber 101, making the addition process more convenient and accurate, and reducing the spillage of slurry.

[0025] The outer end of the anti-seepage extension pipe 2 is provided with an embedded annular groove 201, and an anti-seepage felt sleeve 202 is fitted inside the embedded annular groove 201. The embedded annular groove 201 provides a precise installation and positioning space for the anti-seepage felt sleeve 202. The anti-seepage felt sleeve 202 can further fill the tiny gaps between the anti-seepage extension pipe 2 and the inner wall of the receiving pipe 6, enhance the sealing performance between the two, and effectively reduce the leakage of slurry from the gaps.

[0026] The outer end of the limiting ring 3 is provided with a first sealing ring groove 301, and the receiving pipe 6 is provided with a second sealing ring groove 601 corresponding to the first sealing ring groove 301 near the outer edge of the limiting ring 3. The setting of the first sealing ring groove 301 and the second sealing ring groove 601 provides space for subsequent installation of sealing structure, which helps to further enhance the sealing performance at the connection between the limiting ring 3 and the receiving pipe 6 and prevent ore liquid leakage.

[0027] Two sets of semi-circular sealing rings 4 are symmetrically provided on their adjacent sides with two sets of semi-circular arc-shaped sealing strips 401. The two sets of semi-circular arc-shaped sealing strips 401 correspond to the first sealing ring groove 301 and the second sealing ring groove 601, respectively. A rubber sealing strip 402 is attached between the two sets of semi-circular arc-shaped sealing strips 401. The semi-circular arc-shaped sealing strips 401 can be embedded into the corresponding sealing ring grooves to play a positioning and initial sealing role. The rubber sealing strip 402 can further fill the gaps and enhance the sealing effect.

[0028] Both ends of the two sets of semi-circular sealing rings 4 are provided with connecting blocks 403. The surface of the connecting blocks 403 is symmetrically provided with two sets of connecting holes 404. Through the setting of the connecting blocks 403 and connecting holes 404, it is convenient to tightly fix the two sets of semi-circular sealing rings 4 together with bolts, so that the semi-circular sealing rings 4 can be firmly clamped at the connection between the limiting ring 3 and the receiving pipe 6, ensuring the installation stability of the sealing rings.

[0029] During operation, the operator first precisely inserts the anti-leakage extension pipe 2 on one side of the feed pipe 1 into the receiving pipe 6 of the ball mill body 5, ensuring that the outer wall of the anti-leakage extension pipe 2 is completely in contact with the inner wall of the receiving pipe 6. At the same time, the limiting ring 3 at the outer end of the feed pipe 1 is aligned with the outer end of the receiving pipe 6. Next, two sets of semi-circular sealing rings 4 are taken out, and the semi-circular arc-shaped sealing strip 401 on the inner side of each set of semi-circular sealing rings 4 is embedded into the first sealing ring groove 301 of the limiting ring 3 and the second sealing ring groove 601 of the receiving pipe 6, respectively. At this time, the two sets of semi-circular sealing rings 4 will be spliced ​​into a complete ring structure, which is clamped at the connection between the limiting ring 3 and the receiving pipe 6. Subsequently, the two sets of semi-circular sealing rings 4 are tightly fixed with bolts through the connecting holes 404 on the connecting blocks 403 at both ends of the semi-circular sealing rings 4. During the fixing process, attention should be paid to uniform force to avoid deformation of the sealing structure due to excessive local force.

[0030] Its working principle is as follows: the anti-leakage extension pipe 2 is inserted into the receiving pipe 6, and its outer wall is tightly fitted with the inner wall of the receiving pipe 6 to form the first physical sealing barrier, which can prevent most of the slurry from leaking from the connection between the two. Secondly, an anti-leakage felt sleeve 202 is installed in the embedded annular groove 201 at the outer end of the anti-leakage extension pipe 2. The anti-leakage felt sleeve 202 has good elasticity and sealing performance, which can fill the tiny gaps between the anti-leakage extension pipe 2 and the inner wall of the receiving pipe 6, further enhancing the sealing effect and forming the second sealing defense line. Finally, the semi-circular arc-shaped sealing strip 401 of the semi-circular sealing pressure ring 4 is embedded in the first sealing ring groove 301 and the second sealing ring groove 601 at the connection between the limiting ring 3 and the receiving pipe 6, and the rubber sealing strip 402 will fully fill the gap. At the same time, the two sets of semi-circular sealing pressure rings 4 are tightly fixed by bolts, generating uniform radial pressure at the connection, making the sealing structure tighter and forming the third sealing guarantee.

[0031] Its beneficial effects are significant. This application, through the design of a multi-seal structure consisting of a leak-proof extension pipe 2, a leak-proof felt sleeve 202, and a semi-circular sealing pressure ring 4, effectively prevents slurry from leaking from the connection points during transportation. This not only avoids waste of raw materials and reduces production costs, but also reduces the corrosion of surrounding equipment components by the slurry, lowers cleaning and maintenance costs, and reduces the risk of environmental pollution. The propulsion screw 102 rotates under the drive motor 106, which can more stably and evenly transport the slurry into the ball mill body 5, avoiding the uneven slurry transportation problem that may occur in traditional feeding methods, ensuring the uniform distribution of slurry in the ball mill body 5, thereby improving the grinding effect. The motor cover 107 is fitted on the outer end of the drive motor 106, which can effectively prevent the drive motor 106 from being affected by the external environment, such as the intrusion of dust and moisture, reducing the failure rate of the drive motor 106, extending the service life of the drive motor 106, and reducing equipment maintenance and replacement costs.
