Abstract
Description
Technical Field
[0001] This utility model relates to the field of zircon sand processing technology, specifically a zircon sand wet mixing and homogenization device. Background Technology
[0002] Wet mixing of zircon sand is a core pretreatment step in the wet zircon sand beneficiation process. It specifically refers to the process of using water as a medium to prepare zircon sand powder into a fluid slurry state, and then using mechanical mixing to ensure thorough and uniform mixing of zircon sand particles with beneficiation reagents and water. This provides a stable and homogeneous slurry for subsequent impurity removal, purification, and screening operations. Due to the high density, fast settling velocity, and high particle hardness of zircon sand, conventional mixing methods are prone to problems such as material settling, uneven mixing, and bottom accumulation, directly affecting the purity and yield of the zircon sand beneficiation product. Therefore, specifically optimizing the structure of the wet mixing equipment is key to achieving refined and efficient zircon sand beneficiation processing.
[0003] Currently, traditional zircon sand wet mixing devices in the industry generally adopt a single mixing structure with a fixed tank and a unidirectional rotating mixing rod. The overall motion mode is simple, which has inherent technical defects. Conventional equipment relies solely on the unidirectional circular stirring of the stirring rod and blades to achieve slurry mixing. The bottom of the tank remains stationary throughout the process without any auxiliary movement. For high-density, easily settling zircon sand slurry, the lateral stirring force alone cannot effectively overcome the gravity settling effect of the particles. This results in some zircon sand particles continuously depositing at the bottom of the tank, forming a material accumulation layer. The material deposited at the bottom is not easy to participate in the mixing of the upper slurry, and it is prone to caking and compaction, causing material waste. This also results in differences in the concentration of slurry and the reagent ratio between the upper and lower layers of the tank, affecting the overall material homogenization effect.

Vertically located inside the tank, the top end of the rotating rod penetrates the tank and is rotatably connected to the tank. The top end of the rotating rod is fixedly connected to the output shaft of the motor. A first stirring blade is fixedly attached to the bottom end of the rotating rod and is located inside the lower part of the tank. A sleeve plate is fixedly fitted onto the outer wall of the tank and is fixedly connected to the vertical plate. A circular plate is rotatably connected to the bottom end of the tank.

[0007] Optionally, it further includes: a sealing strip abutting between the scraper and the circular plate; and two bolts arranged from front to back at the bottom end of the circular plate, the bolts passing through the circular plate and the sealing strip and being threadedly connected to the scraper.
[0008] Optionally, it further includes: a housing rotatably connected to the outer wall of the rotating rod; a first bevel gear located inside the housing, the inner wall of the first bevel gear being fixedly connected to the rotating rod; two second bevel gears, each meshing with the other two sides of the first bevel gear; two crossbars, each rotatably connected to the other two sides of the housing, the crossbars being fixedly connected to the second bevel gears; multiple second stirring blades, a portion of which are fixedly attached to the outer wall of one crossbar and another portion to the outer wall of another crossbar; and two connecting rods, each fixedly attached to the top two sides of the housing, the end of the connecting rod away from the housing being fixedly connected to the inner top of the tank.
[0009] Optionally, it further includes: a first protective cover, which is sleeved on the outside of the third and fourth synchronous pulleys, the first protective cover is fixedly connected to the vertical plate, the first protective cover is rotatably connected to the vertical rod, and the first protective cover is rotatably connected to the rotating rod; and a second protective cover, which is sleeved on the outside of the first and second synchronous pulleys, the second protective cover is fixedly connected to the vertical plate, the second protective cover is rotatably connected to the vertical rod, and the second protective cover is rotatably connected to the round rod.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This zircon sand wet mixing and homogenizing device has the following advantages: Through the coordinated operation of various components, the operator first feeds the zircon sand particles to be stirred, mineral processing reagents, and an appropriate amount of water into the tank through the feeding hopper. The motor is then started, driving the rotating rod and the first stirring blade to rotate. The rotating first stirring blade can mix the materials inside the tank as a whole. At the same time, the rotating rod is driven by the transmission component to drive the circular plate and scraper to rotate in opposite directions. During the operation, the scraper continuously scrapes the settled material at the bottom of the tank, scooping up and lifting the material deposited at the bottom of the tank, so that the bottom material can fully enter the mixing area and receive the stirring action of the first stirring blade. This effectively breaks up the sedimentation and agglomeration of the bottom material, eliminates the material accumulation layer at the bottom of the tank, and allows the bottom settled material to continuously surge upward and participate in the overall material mixing, balancing the slurry concentration and reagent ratio between the upper and lower layers of the tank, and improving the uniformity and mixing quality of the zircon sand slurry.
[0011] After the motor starts, the fourth synchronous pulley rotates synchronously with the rotating rod. Through the transmission action of the synchronous belt, it drives the third synchronous pulley, the vertical rod and the second synchronous pulley to rotate synchronously. Then, through the cross synchronous belt transmission, it drives the first synchronous pulley, the round rod, the round disc, the round plate and the scraper to rotate synchronously in the opposite direction. The linkage operation of stirring and scraping at the bottom of the tank can be realized with only a single motor, which effectively reduces the operating cost of the equipment.
[0012] After the motor starts, the first bevel gear rotates synchronously with the rotating rod. Through gear meshing, it drives the second bevel gears on both sides, the crossbar, and the second stirring blade to rotate synchronously. The horizontally arranged second stirring blade can enhance the turbulent flow and churning effect of the material inside the tank, further improving the mixing uniformity and overall material quality of the zircon sand slurry.

[0016] 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.
[0017] Please see Figures 1 to 6 The technical solution provided by this utility model is as follows: A zircon sand wet mixing and homogenizing device, comprising: a vertical plate 2, a bottom plate 1, the bottom plate 1 being fixedly connected to the bottom end of the vertical plate 2, a tank 3, the tank 3 being located on one side of the vertical plate 2, a feeding hopper 4, the feeding hopper 4 being fixedly installed on one side of the top end of the tank 3, a discharge valve 5, the discharge valve 5 being fixedly installed on one side of the bottom end of the tank 3, a motor 6, the motor 6 being located above the tank 3, four support columns 7, the four support columns 7 being fixedly connected to the four corners of the motor 6 housing respectively, the ends of the support columns 7 away from the motor 6 being fixedly connected to the tank 3, and a rotating rod 8, the rotating rod 8 being vertically located at... Inside the tank body 3, the top end of the rotating rod 8 passes through the tank body 3 and is rotatably connected to the tank body 3. The top end of the rotating rod 8 is fixedly connected to the output shaft of the motor 6. The first stirring blade 9 is fixedly connected to the bottom end of the rotating rod 8 and is located inside the lower part of the tank body 3. The sleeve plate 10 is fixedly sleeved on the outer wall of the tank body 3 and is fixedly connected to the vertical plate 2. The circular plate 11 is rotatably connected to the bottom end of the tank body 3. The scraper 12 is set on the upper surface of the circular plate 11. The transmission assembly connects the circular plate 11 to the rotating rod 8.
[0018] In the specific implementation process, it is worth noting that the vertical plate 2 and the bottom plate 1 together form the rigid support frame of the device, ensuring the installation stability and load-bearing strength of the tank 3. The tank 3 is a closed mixing chamber that can hold zircon sand slurry and avoid material splashing during the mixing process. The feeding hopper 4 has a bucket-shaped structure that is wider at the top and narrower at the bottom, which can guide the material to fall smoothly into the tank and reduce material spillage. The top of the feeding hopper 4 is hinged with a hopper cover. The discharge valve 5 is used to control the discharge rhythm of the slurry after mixing. A specific model can be selected as needed. The four pillars 7 suspend the motor 6 above the tank 3, leaving sufficient installation space for the top transmission components. The sleeve plate 10 is used for rigid connection and fixation between the tank 3 and the vertical plate 2. The circular plate 11 provides the installation bearing base for the scraper 12. The circular plate 11 is rotatably connected to the tank 3 through a sealed bearing. The transmission component can synchronously transmit the power of the rotating rod 8 to the bottom circular plate 11.
[0019] Furthermore, the transmission assembly includes: two protruding rods 15, which are respectively fixed to both sides of the lower surface of the circular plate 11; a circular disc 16, which is fixed to the bottom end of the protruding rods 15; a circular rod 17, which is fixed to the center of the lower surface of the circular disc 16; a first synchronous pulley 18, which is fixed to the bottom end of the circular rod 17; and a vertical rod 19, which is vertically arranged between the tank body 3 and the vertical plate 2, and is rotatably connected to the sleeve plate 10. Synchronous pulley 20, the second synchronous pulley 20 is fixed to the bottom end of the vertical rod 19, cross synchronous belt 21, the second synchronous pulley 20 is connected to the first synchronous pulley 18 through the cross synchronous belt 21, the third synchronous pulley 22 is fixed to the top end of the vertical rod 19, the fourth synchronous pulley 23 is fixedly sleeved on the top end of the outer wall of the rotating rod 8, synchronous belt 24, the fourth synchronous pulley 23 is connected to the third synchronous pulley 22 through the synchronous belt 24.
[0020] In the specific implementation process, it is worth noting that the protruding rod 15 is used to connect the circular plate 11 and the disc 16, transmitting rotational torque while distributing the force. The disc 16 can evenly transmit the rotational power from the circular rod 17, ensuring that the bottom scraping structure operates smoothly without eccentric load. The circular rod 17, as the bottom driven shaft, transmits the power of the first synchronous pulley 18 upward to the disc 16. The vertical rod 19, as the intermediate transmission shaft, relies on the rotational support provided by the sleeve plate 10 to achieve stable vertical transmission of power. The cross synchronous belt 21 adopts a cross-winding method, which can change the transmission direction and realize the reverse operation of the first synchronous pulley 18 and the second synchronous pulley 20. The cross synchronous belt 21 and the synchronous belt 24 mesh with each synchronous pulley for transmission, with precise transmission ratio and smooth operation.
[0021] Furthermore, it also includes: a sealing strip 13, which abuts between the scraper 12 and the circular plate 11; and two bolts 14, which are arranged from front to back at the bottom of the circular plate 11. The bolts 14 pass through the circular plate 11 and the sealing strip 13 in sequence and are threadedly connected to the scraper 12.
[0022] In the specific implementation process, it is worth noting that the sealing strip 13 is made of wear-resistant and corrosion-resistant rubber material and fills the assembly gap between the scraper 12 and the circular plate 11. This can prevent slurry from seeping into the connection gap and improve the tightness of the scraper 12 installation. The bolts 14 adopt the bottom-through installation method, and are installed sequentially from the bottom end of the circular plate 11 upwards. The threaded connection structure is easy to disassemble and assemble, which facilitates the disassembly and replacement of the scraper 12 and the sealing strip 13 after wear. Moreover, the head of the bolt 14 is not exposed on the scraping working surface of the scraper 12, so it will not interfere with the scraping operation of the bottom material.
[0023] Furthermore, it also includes: a housing 25, which is rotatably connected to the outer wall of the rotating rod 8; a first bevel gear 26, which is located inside the housing 25 and whose inner wall is fixedly connected to the rotating rod 8; two second bevel gears 27, which are respectively meshed and connected to both sides of the first bevel gear 26; two crossbars 28, which are respectively rotatably connected to both sides of the housing 25 and fixedly connected to the second bevel gears 27; multiple second stirring blades 29, with some second stirring blades 29 fixedly connected to the outer wall of one crossbar 28 and others fixedly connected to the outer wall of another crossbar 28; and two connecting rods 30, which are respectively fixedly connected to both sides of the top of the housing 25 and whose ends away from the housing 25 are fixedly connected to the inner top of the tank 3.
[0024] In the specific implementation process, it is worth noting that the shell 25 provides a closed protective space for the bevel gear transmission structure, preventing the slurry from eroding the gear components, and at the same time provides stable rotational support for the crossbar 28. The first bevel gear 26 rotates synchronously with the rotating rod 8, and the vertical rotation is converted into horizontal rotation through bevel gear meshing, driving the second bevel gears 27 on both sides to operate synchronously. The two crossbars 28 are symmetrically arranged, respectively bearing the second stirring blade 29 and transmitting rotational power. The horizontal rotation trajectory of the second stirring blade 29 can form a cross turbulent flow field with the vertical stirring trajectory of the first stirring blade 9, enhancing the convective mixing effect of the slurry. The two connecting rods 30 fix the shell 25 to the top of the tank 3, ensuring that the shell does not rotate synchronously with the rotating rod 8, and ensuring the stable operation of the bevel gear transmission structure.
[0025] Furthermore, it also includes: a first protective cover 31, which is sleeved on the outside of the third synchronous pulley 22 and the fourth synchronous pulley 23, the first protective cover 31 is fixedly connected to the vertical plate 2, the first protective cover 31 is rotatably connected to the vertical rod 19, and the first protective cover 31 is rotatably connected to the rotating rod 8; and a second protective cover 32, which is sleeved on the outside of the first synchronous pulley 18 and the second synchronous pulley 20, the second protective cover 32 is fixedly connected to the vertical plate 2, the second protective cover 32 is rotatably connected to the vertical rod 19, and the second protective cover 32 is rotatably connected to the round rod 17.
[0026] In the specific implementation process, it is worth noting that both the first protective cover 31 and the second protective cover 32 are made of sheet metal bending to protect their corresponding internal structural components, which can prevent exposed rotating parts from causing safety hazards and improve the safety of equipment operation. The first protective cover 31 and the second protective cover 32 have a suitable rotation gap with each rotating shaft, which will not interfere with the normal rotation of the transmission shaft.
[0027] Working principle: Mix all materials thoroughly. During the wet mixing process of zircon sand, the operator first feeds the zircon sand particles to be processed, the matching mineral processing reagents, and a measured amount of water into the tank 3 through the feeding hopper 4. After the material is filled, the equipment motor 6 is started. The motor 6 outputs power to drive the rotating rod 8 and the first stirring blade 9 fixed on the rotating rod 8 to rotate. The rotating first stirring blade 9 can mix the slurry inside the tank 3. At the same time, the continuously rotating rod 8 completes the power transmission through the transmission component, thereby driving the circular plate 11. The scraper 12 rotates in the opposite direction to the rotating rod 8 and the first stirring blade 9. During continuous operation, the scraper 12 scrapes against the inner wall of the bottom of the tank 3 and rotates. This can continuously scoop up and lift the zircon sand material that has settled and accumulated at the bottom of the tank, breaking up the problem of material deposition, agglomeration and solidification at the bottom of the tank, eliminating the material accumulation layer structure at the bottom of the tank 3, promoting full convection and fusion of the upper and lower layers of slurry in the tank 3, effectively balancing the concentration of the upper and lower layers of slurry and the accuracy of the reagent ratio in the tank 3, and improving the overall uniformity of the zircon sand slurry and the quality of the mixing operation.
[0028] Single-motor linkage transmission operation: When motor 6 starts and drives the rotating rod 8 to rotate, the fourth synchronous pulley 23, which is fixed outside the rotating rod 8, rotates synchronously and coaxially with the rotating rod 8. Relying on the closed-loop transmission effect of synchronous belt 24, it drives the third synchronous pulley 22, the vertical rod 19 and the second synchronous pulley 20 to rotate synchronously and in a directional manner. On this basis, the second synchronous pulley 20 realizes secondary power transmission through the cross synchronous belt 21, thereby driving the first synchronous pulley 18, the round rod 17, the round disc 16 and the bottom round plate 11 and scraper 12 to rotate synchronously in the opposite direction. Relying on a single motor 6 as the only power source, no additional drive equipment is required to synchronously realize the stirring of materials inside the tank 3, thereby reducing the operating cost of the equipment.
[0029] Enhanced turbulent mixing of slurry: When the motor 6 drives the rotating rod 8 to rotate, the first bevel gear 26 fixed on the rotating rod 8 rotates synchronously. Through the bevel gear meshing transmission principle, it synchronously drives the second bevel gear 27, the crossbar 28 and the second stirring blade 29 at the end, which are symmetrically arranged on both sides, to rotate. The second stirring blade 29, which is symmetrically arranged laterally, can form a lateral shearing stirring force inside the tank 3, and form a cross turbulent flow field with the longitudinal stirring trajectory of the first stirring blade 9. This enhances the multi-dimensional turbulent surging and convection mixing effect of the material. Through the coordinated cooperation of the primary and secondary stirring structures, the problems of insufficient mixing and uneven local material ratio that exist in a single stirring structure are solved. This further refines the fusion effect of zircon sand particles with mineral processing reagents and water, and improves the mixing uniformity and overall material quality of zircon sand slurry.
