Description

Technical Field

[0001] This utility model belongs to the field of mineral screening technology, specifically relating to a gold mine powder beneficiation device. Background Technology

[0002] In the gold mine beneficiation process, powder screening is an indispensable and crucial step. Its purpose is to classify ore powder according to particle size, selecting raw materials that meet the requirements of subsequent refining processes while separating out oversized particles. However, current gold mine powder beneficiation equipment on the market suffers from the following problems:

[0003] From the perspective of screening efficiency, traditional mineral processing equipment mostly uses fixed screens or simple vibrating screen structures. After prolonged use, fixed screens are prone to clogging by the ore, leading to a significant decrease in screening efficiency and requiring frequent shutdowns for cleaning. This not only consumes a large amount of manpower and time but also reduces overall production efficiency. While vibrating screen structures can reduce clogging to some extent, the amplitude and frequency of vibration are difficult to control precisely, easily resulting in incomplete screening. This leads to some qualified particles being mixed with oversized particles, increasing the difficulty and cost of subsequent processing.

[0004] Furthermore, gold ore powder has a complex composition, often containing sticky substances and fine mud, which easily adhere to the surface of the screen openings, causing blockages. Once the screen openings are blocked, the ore cannot pass through the screen smoothly, accumulating on the screen surface and further hindering the screening process. Currently, the main methods for solving screen blockage are manual cleaning or washing with a high-pressure water gun. Manual cleaning is labor-intensive, inefficient, and poses safety hazards; while high-pressure water gun washing can quickly clean the screen openings, it increases the moisture content of the ore, affecting subsequent drying and refining processes, and may also lead to water waste and environmental pollution. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a gold mine powder beneficiation device that solves the problems of low screening efficiency and difficult-to-clean screen blockage in existing gold mine powder beneficiation devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a gold mine powder beneficiation device, comprising a frame, with side frame one and side frame two fixed at both ends of the frame respectively. A reduction motor is installed on side frame one, and the reduction motor drives a main shaft. Bearing seats connected to both ends of the main shaft are respectively installed on side frame one and side frame two. Drive rings are also fixed at both ends of the main shaft. One drive ring is connected to one end of a connecting rod. The connecting rod and the other drive ring are respectively connected to both ends of a screen cylinder. The screen cylinder has screen holes. A spiral plate is fixed inside the screen cylinder. A guide groove is installed on both the connecting rod and the frame below the screen cylinder. A cleaning component is installed on the guide groove on one side of the screen cylinder. The cleaning component includes a bearing seat, which is fixed on the guide groove. A rubber-coated roller is rotatably installed on the bearing seat. The curved side of the rubber-coated roller is pressed tightly against the curved side of the screen cylinder, and the axis of the rubber-coated roller is parallel to the axis of the screen cylinder. Multiple protrusions are formed on the rubber-coated roller.

[0007] The beneficial effects of this utility model are as follows: when the screen cylinder rotates, it screens out ore powder with qualified particle size, while raw materials exceeding the limit are discharged at the connecting rod under the conveying of the spiral plate, realizing efficient and continuous screening of materials; the rubber-coated roller can be driven to rotate by the screen cylinder, thereby causing the protrusions to push out the ore material blocking the screen holes, realizing automatic cleaning of the screen holes.

[0008] In order to effectively clean the ore clogging the screen holes by using the cleaning component;

[0009] As a further improvement to the above technical solution: multiple screen holes are equidistantly spaced around the axis of the screen cylinder, and the number of protrusions is multiple and equidistantly spaced around the axis of the rubber-coated roller. The arc length of the rubber-coated roller between the centers of two rows of adjacent screen holes is equal to the arc length of the screen cylinder between the centers of two rows of adjacent screen holes.

[0010] The beneficial effects of this improvement are: when the rubber-coated roller is driven to rotate by the screen cylinder, the protrusions can be adapted to be inserted into the screen holes as the rubber-coated roller rotates, thereby effectively ejecting the ore material that is blocked in the screen holes.

[0011] To avoid deformation and damage to the cleaning components due to excessive resistance in the ejection of the ore;

[0012] As a further improvement to the above technical solution: the protrusion is a hemispherical rubber block structure.

[0013] The beneficial effects of this improvement are: the harder bump itself has good elasticity, which can produce elastic contraction when the ejection resistance of the ore is too great, thus avoiding deformation and damage to the rubber-coated roller.

[0014] To ensure the stability of the rotation of the drive ring, connecting rod, and screen cylinder;

[0015] As a further improvement to the above technical solution: support wheels are also installed on the side frame one and side frame two. The support wheels are arranged on the left and right sides of the drive ring axis, and the rollers in the support wheels are tactilely connected to the drive ring. The axis of the rollers in the support wheels is parallel to the axis of the main shaft.

[0016] The beneficial effects of this improvement are: the support wheel can roll to support the drive ring, reducing the force on the main shaft in the radial direction and ensuring the stability of the rotation of the drive ring, connecting rod, and screen cylinder.

[0017] To effectively prevent material from splashing out of the screen cylinder;

[0018] As a further improvement to the above technical solution: a baffle is installed on one side of the side frame two facing the port of the drive ring.

[0019] The beneficial effect of this improvement is that the baffle acts as a material stopper, preventing the ore from being bounced out when it falls into the inside of the screen cylinder.

[0020] To avoid the vibration generated during the operation of the drive ring, connecting rod, and screen cylinder affecting the working stability of the geared motor;

[0021] As a further improvement to the above technical solution: the geared motor is driven and connected to the main shaft through a chain drive mechanism, a drive sprocket is installed on the output shaft of the geared motor, and a driven sprocket is installed at one end of the main shaft.

[0022] The beneficial effects of this improvement are: the chain drive mechanism can prevent vibration from being directly transmitted to the output shaft of the geared motor, thus avoiding structural damage to the geared motor.

[0023] In order to efficiently convey the material in the screen cylinder;

[0024] As a further improvement to the above technical solution: the two ends of the spiral plate are flush with the two ends of the screen cylinder, and there are multiple spiral plates, which are equidistantly spaced around the axis of the screen cylinder.

[0025] The beneficial effect of this improvement is that when multiple spiral plates rotate synchronously with the screen cylinder, the ore inside the screen cylinder can be stably conveyed towards the connecting rod.

[0026] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0033] Example 1:

[0034] like Figure 1 — Figure 4As shown: A gold mine powder beneficiation device includes a frame 1, with side frames 2 and 5 fixed at both ends of the frame 1 respectively. A reduction motor 3 is mounted on the side frame 2, and the reduction motor 3 drives a main shaft 4. Bearing seats 101 connected to both ends of the main shaft 4 are respectively mounted on the side frames 2 and 5. Drive rings 6 are also fixed at both ends of the main shaft 4. One drive ring 6 is connected to one end of a connecting rod 7. The connecting rod 7 and the other drive ring 6 are respectively connected to both ends of a screen cylinder 8. The screen cylinder 8 has screen holes 81. A spiral plate 82 is fixed inside the screen cylinder 8. The connecting rod 7 and the screen cylinder 8 are located below... Each frame 1 is equipped with a guide chute 9. A cleaning component 10 is installed on the guide chute 9 on one side of the screen cylinder 8. The cleaning component 10 includes a bearing seat 101, which is fixed on the guide chute 9. A rubber-coated roller 102 is rotatably mounted on the bearing seat 101. The curved side of the rubber-coated roller 102 is pressed tightly against the curved side of the screen cylinder 8, and the axis of the rubber-coated roller 102 is parallel to the axis of the screen cylinder 8. Multiple protrusions 103 are formed on the rubber-coated roller 102. When the screen cylinder 8 rotates, it screens out ore powder with qualified particle size. The raw materials exceeding the limit are discharged at the connecting rod 7 under the conveying of the spiral plate 82, so as to realize the efficient and continuous screening of materials.The rubber-coated roller 102 can be driven to rotate by the screen cylinder 8, thereby causing the protrusions 103 to push out the ore blocked in the screen holes 81, realizing the automatic cleaning of the screen holes 81. Multiple screen holes 81 are equidistantly arranged around the axis of the screen cylinder 8. Multiple protrusions 103 are also equidistantly arranged around the axis of the rubber-coated roller 102. The arc length of the rubber-coated roller 102 between the centers of two rows of adjacent screen holes 81 is equal to the arc length of the screen cylinder 8 between the centers of the two rows of adjacent screen holes 81. The rubber-coated roller 102 is driven to rotate by the screen cylinder 8. At the same time, the protrusion 103 can be adapted to be inserted into the screen hole 81 as the rubber-coated roller 102 rotates, thereby effectively ejecting the ore material blocked in the screen hole 81. The protrusion 103 is a hemispherical rubber block structure. The relatively hard protrusion 103 itself also has good elasticity. It can elastically contract when the ejection resistance of the ore material is too large, avoiding deformation and damage to the rubber-coated roller 102. Support wheels 11 are also installed on the side frame 1 2 and the side frame 2 5. The support wheels 11 are located on the left and right sides of the axis of the drive ring 6. The rollers in the support wheel 11 are connected to the drive ring 6, and the axis of the rollers in the support wheel 11 is parallel to the axis of the main shaft 4. The support wheel 11 can support the drive ring 6 by rolling, reducing the radial force on the main shaft 4 and ensuring the stability of the rotation of the drive ring 6, connecting rod 7, and screen cylinder 8. A baffle 12 is installed on the side of the side frame 5 facing the port of the drive ring 6. The baffle 12 acts as a material stopper, preventing the ore from being bounced out when it falls into the screen cylinder 8. The reduction motor 3 is connected to the main shaft 4 through a chain drive mechanism. A drive sprocket is installed on the output shaft of the reduction motor 3, and a driven sprocket is installed at one end of the main shaft 4. The chain drive mechanism can prevent vibration from being directly transmitted to the output shaft of the reduction motor 3, causing structural damage to the reduction motor 3. The two ends of the spiral plate 82 are flush with the two ends of the screen cylinder 8, and there are multiple spiral plates 82, which are equidistantly arranged around the axis of the screen cylinder 8. When multiple spiral plates 82 rotate synchronously with the screen cylinder 8, they can stably transport the ore inside the screen cylinder 8 towards the connecting rod 7.

[0035] The working principle of this technical solution is as follows: The gold ore powder to be screened is conveyed into the screen cylinder 8 through a suitable feeding device. The reduction motor 3 is started, and the reduction motor 3 drives the main shaft 4 to rotate through the chain transmission mechanism. The main shaft 4 drives the drive rings 6 at both ends to rotate, thereby causing the connecting rod 7 and the screen cylinder 8 to rotate accordingly. During the rotation of the screen cylinder 8, the screen holes 81 screen the ore. The ore powder with qualified particle size falls into the guide chute 9 below through the screen holes 81 and is conveyed to the subsequent processing steps. The spiral plate 82 inside the screen cylinder 8 rotates synchronously with the screen cylinder 8, stably guiding the ore inside the screen cylinder 8 towards the connecting rod 7. Oversized raw materials are discharged at the connecting rod 7 under the push of the spiral plate 82 and fall into the corresponding guide trough 9, realizing efficient and continuous screening of materials. While the screen cylinder 8 rotates, the rubber-coated roller 102, which is pressed tightly against the curved side of the screen cylinder 8, is driven to rotate by the screen cylinder 8. Since multiple protrusions 103 are equidistantly arranged around the axis of the rubber-coated roller 102 and their positions are adapted to the screen holes 81, as the rubber-coated roller 102 rotates, the protrusions 103 can be inserted into the screen holes 81 in sequence, effectively pushing out the ore blocked in the screen holes 81, realizing automatic cleaning of the screen holes 81, and ensuring the continuous and efficient screening process.
