Quartz ore washing and drying line

Abstract

The present application relates to the technical field of drying, and discloses a quartz ore washing and drying line, which comprises an operation table. The drying box of the present application is characterized in that the thickness of the quartz ore on the side close to the air inlet pipe is smaller than that on the other side, so that the ore in this area can be more fully contacted with the high-temperature gas conveyed, greatly improving the drying efficiency and avoiding the problem of incomplete local drying caused by ore accumulation. At the same time, the driving motor drives the synchronous shaft and the cam to rotate, and the angle of the drying box is changed by cooperating with the lifting rod inserted into the side wall of the drying box, so that the quartz ore can continuously slide to the side of the air inlet pipe, ensuring that the ore can gradually enter the area where it can be more fully contacted with the high-temperature gas, and further optimizing the drying effect. In addition, when the pushing plate on the synchronous shaft moves to the lower side, it can not only block part of the quartz ore, but also orderly discharge the quartz ore that has been fully dried on the side close to the air inlet pipe from the drying box, ensuring that the unloading process is adapted to the drying rhythm, and taking into account the drying quality and the smoothness of operation.

Description

Technical Field

[0001] This invention belongs to the field of drying technology, specifically, it relates to a quartz ore washing and drying line. Background Technology

[0002] In the quartz ore processing industry, washing is a crucial pretreatment process for removing surface impurities and improving ore purity. The drying process after washing directly affects the efficiency and quality of subsequent processing steps such as crushing and purification. Therefore, the performance of the drying equipment has a significant impact on the overall quartz ore processing flow. Currently, most commonly used quartz ore drying equipment in the industry employs box-type drying mechanisms or simple drum-type drying mechanisms. Their core operation involves feeding a large quantity of washed quartz ore into the drying chamber, where high-temperature gas is introduced to evaporate the moisture.

[0003] However, these existing devices have significant drawbacks in practical applications: on the one hand, in pursuit of single-batch processing volume, a large amount of raw materials accumulate in the drying chamber with a thick layer. Even with a simple turning structure, only the surface and middle layers of ore can be turned over. The bottom and deep layers of ore are difficult to fully contact the high-temperature gas due to compression and coverage, resulting in poor heat transfer, long drying time at the bottom, and low overall efficiency. On the other hand, since the raw materials are mixed together, it is necessary to wait until all the ore in the chamber meets the standards before unloading. This not only easily leads to over-drying of the already dried ore but also causes energy waste and prolongs the single-batch operation time, thus restricting the overall production capacity.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0006] A quartz ore washing and drying line includes an operating table.

[0007] The operating table is rotatably mounted with a drying box for drying quartz ore, and the drying box is tilted. The drying box is equipped with an air inlet pipe and an air outlet pipe. The air inlet pipe is connected to a high-temperature gas conveying system. The air inlet pipe is higher than the air outlet pipe, and the thickness of the quartz ore on the side closer to the air inlet pipe is less than the thickness of the quartz ore on the other side.

[0008] A synchronous shaft is rotatably mounted on the operating table, with a drive motor mounted on one end of the synchronous shaft and a cam mounted on the other end. A lifting rod is inserted into the side wall of the drying box, with one end of the lifting rod fitting against the bottom of the cam and the other end of the lifting rod contacting the operating table. The cam rotates and changes the angle of the drying box through the lifting rod, causing the quartz ore to slide towards the air inlet pipe.

[0009] Pusher plates are installed on the synchronous shafts, and insert rods are installed on the pusher plates. The ends of the insert rods are slidably connected to guide plates installed on the side wall of the drying chamber. Protrusions are installed on the guide plates. When the pusher plate moves downward and blocks a portion of the quartz ore, and the insert rod contacts the protrusions, it drives the pusher plate to move, thereby driving the quartz ore near the air inlet pipe to be discharged from the drying chamber.

[0010] In a preferred embodiment of the present invention, the bottom of the operating table is equipped with four support legs, each of which is equipped with an anti-slip pad. Several pairs of reinforcing ribs are installed between adjacent support legs, and the heights of the adjacent reinforcing ribs are different.

A feeding door is installed on one side of the drying box, and the feeding door is away from the side of the air inlet pipe. A connecting flange is installed at the end of both the air inlet pipe and the air outlet pipe, and an installation hole is opened on the connecting flange. An observation window is installed on the surface of the drying box.

[0012] In a preferred embodiment of the present invention, a positioning seat is rotatably mounted on the synchronous shaft, the positioning seat is installed on the inner side wall of the drying chamber, a turntable is installed on the side wall of the synchronous shaft, a slide rail is installed on the inner side wall of the turntable, a positioning sleeve is installed on the side wall of the drying chamber, a sliding groove is formed on the inner side wall of the positioning sleeve, the sliding groove is slidably connected to the slide rail, and a bracket is mounted on the drive motor, the end of the bracket being connected to the side wall of the drying chamber.

[0013] In a preferred embodiment of the present invention, a plurality of pairs of stirring rods are mounted on the synchronous shaft, the plurality of pairs of stirring rods are spirally distributed, and each stirring rod is equipped with a stirring plate, the stirring plate being inclined.

[0014] In a preferred embodiment of the present invention, a feeding plate is also installed on the surface of the synchronous shaft. The feeding plate and the pusher plate are located at both ends of the drying box, respectively. A synchronous frame is installed on the feeding plate, and the other end of the synchronous frame is connected to the pusher plate. The synchronous frame is used to drive the feeding plate and the pusher plate to move synchronously. The feeding plate is used to push the quartz ore to one side of the pusher plate.

[0015] In a preferred embodiment of the present invention, the turntable and the insertion rod are movably connected, a slide rod is installed at the end of the insertion rod, the slide rod is slidably disposed on the side wall of the guide plate, a connecting frame is installed at the bottom of the guide plate, the bottom of the connecting frame is connected to the side wall of the drying chamber, and a slope is provided at the connection between the protrusion and the guide plate.

[0016] In a preferred embodiment of the present invention, a tension spring is installed on the outer wall of the insertion rod located outside the drying box, a baffle is installed on the insertion rod, one end of the tension spring is engaged with the baffle, and the other end of the tension spring is engaged with the positioning sleeve.

[0017] In a preferred embodiment of the present invention, a discharge port is provided at the bottom of the drying chamber near the pusher plate. A sealing door is slidably provided on the discharge port, and a push rod is installed on the sealing door. When the pusher plate moves, the push rod is squeezed to separate the sealing door from the discharge port. A push rod is installed at the bottom of the sealing door, and a push plate is installed at the end of the push rod. A limit seat is slidably provided on the push rod. The limit seat is installed on the side wall of the drying chamber. A limit spring is sleeved on the push rod. One end of the limit spring is engaged with the side wall of the push plate, and the other end of the limit spring is engaged with the limit seat. The bottom of the discharge port corresponds to the receiving hopper installed on the operating table.

[0018] In a preferred embodiment of the present invention, a fixed seat is movably inserted into the lifting rod, the fixed seat is installed on the side wall of the drying oven, a ball bearing is installed at the bottom of the lifting rod and the ball bearing corresponds to the operating table, a pressure plate is installed at the top of the lifting rod and the pressure plate is in contact with the lower surface of the cam, and a return spring is sleeved on the lifting rod, one end of the return spring is engaged with the fixed seat and the other end of the return spring is engaged with the pressure plate.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] The drying chamber of this invention is tilted, with the inlet pipe higher than the outlet pipe. This results in the quartz ore thickness on the side near the inlet pipe being less than on the other side, allowing for more thorough contact between the ore in this area and the high-temperature gas delivered by the high-temperature gas conveying system. This significantly improves drying efficiency and avoids the problem of incomplete drying in certain areas due to ore accumulation. Simultaneously, when the drive motor rotates the synchronous shaft, the cam on the synchronous shaft rotates accordingly. By cooperating with the lifting rod inserted into the side wall of the drying chamber, the angle of the drying chamber is changed, causing the quartz ore to continuously slide towards the inlet pipe side. This ensures that the ore can gradually enter the area with more thorough contact with the high-temperature gas, further optimizing the drying effect. In addition, when the pusher plate on the synchronous shaft moves downward with the synchronous shaft, it can both block some of the quartz ore and move itself through the contact between the rod and the protrusion on the guide plate. This allows the fully dried quartz ore near the inlet pipe to be discharged from the drying chamber in an orderly manner, ensuring that the unloading process matches the drying rhythm and balancing drying quality and operational smoothness.

[0021] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0037] Example 1, such as Figures 1 to 9 As shown, a quartz ore washing and drying line includes an operating table 1.

[0038] A drying box 12 for drying quartz ore is rotatably installed on the operating table 1. The drying box 12 is tilted. The drying box 12 is equipped with an air inlet pipe 122 and an air outlet pipe 123. The air inlet pipe 122 is connected to the high temperature gas conveying system. The air inlet pipe 122 is higher than the air outlet pipe 123. The thickness of the quartz ore on the side closer to the air inlet pipe 122 is less than the thickness of the quartz ore on the other side.

[0039] A synchronous shaft 2 is rotatably mounted on the operating table 1, and a drive motor 21 is mounted on one end of the synchronous shaft 2. A cam 3 is mounted on the other end of the synchronous shaft 2. A lifting rod 311 is inserted into the side wall of the drying box 12. One end of the lifting rod 311 is in contact with the bottom of the cam 3, and the other end of the lifting rod 311 is in contact with the operating table 1. The cam 3 rotates and changes the angle of the drying box 12 through the lifting rod 311, so that the quartz ore slides towards the air inlet pipe 122.

[0040] Pusher plates 24 are installed on the synchronous shaft 2. Insert rods 25 are installed on the pusher plates 24. The end of the insert rods 25 is slidably connected to the guide plate 252 installed on the side wall of the drying box 12. The guide plate 252 is equipped with protrusions 254. When the pusher plate 24 moves to the bottom and blocks a part of the quartz ore, and the insert rod 25 contacts the protrusions 254, it drives the pusher plate 24 to move, thereby driving the quartz ore near the air inlet pipe 122 to be discharged from the drying box 12.

[0041] like Figures 1 to 9 As shown in the specific embodiment, the operating platform 1 has four support legs 11 installed at its bottom. Each of the four support legs 11 has an anti-slip pad on its bottom, and several pairs of reinforcing ribs 111 are installed between adjacent support legs 11, with the heights of the adjacent reinforcing ribs 111 being different. The four support legs 11, together with the anti-slip pads, ensure the overall stability of the operating platform 1, preventing displacement due to vibration during operation. The reinforcing ribs 111 at different heights further enhance the deformation resistance of the support structure and improve the overall rigidity of the equipment.

[0042] like Figures 1 to 9As shown, furthermore, a pair of support seats 121 are installed on the operating table 1. The pair of support seats 121 are connected to the side wall of the drying chamber 12. A feed door 125 is installed on one side of the drying chamber 12, and the feed door 125 is located away from the air inlet pipe 122. Both the air inlet pipe 122 and the air outlet pipe 123 are equipped with connecting flanges 124, and the connecting flanges 124 have mounting holes. An observation window is installed on the surface of the drying chamber 12. The support seats 121 provide a stable rotation support point for the drying chamber 12, ensuring smooth angle adjustment. The design of the feed door 125 being away from the air inlet pipe 122 can prevent the ore from directly accumulating on the side of the air inlet pipe 122 during feeding, which would result in uneven thickness. The connecting flanges 124 facilitate quick docking with the high-temperature gas conveying system, reducing installation difficulty. The observation window allows for real-time monitoring of the drying status inside the chamber, enabling timely detection of abnormalities.

[0043] Example 2 differs from the above examples in that: Figures 1 to 9 As shown, a positioning seat 212 is rotatably mounted on the synchronous shaft 2, and the positioning seat 212 is installed on the inner side wall of the drying chamber 12. A turntable 22 is installed on the side wall of the synchronous shaft 2, and a slide rail 221 is installed on the inner side wall of the turntable 22. A positioning sleeve 222 is installed on the side wall of the drying chamber 12, and a sliding groove 223 is opened on the inner side wall of the positioning sleeve 222. The sliding groove 223 is slidably connected to the slide rail 221. A bracket 211 is mounted on the drive motor 21, and the end of the bracket 211 is connected to the side wall of the drying chamber 12. Several pairs of stirring rods 23 are installed on the synchronous shaft 2, and the pairs of stirring rods 23 are spirally distributed. Each stirring rod 23 is equipped with a stirring plate 231, and the stirring plates 231 are inclined. The positioning seat 212 and the positioning sleeve 222 provide double stable support for the synchronous shaft 2 through the cooperation of the slide rail 221 and the slide groove 223, ensuring its coaxiality during rotation and avoiding shaking that affects the linkage of components; the spirally distributed stirring rod 23 and the inclined stirring plate 231 can fully turn over the ore, break the piled state, greatly increase the contact area between the ore and the high temperature gas, improve the drying uniformity, and reduce the local undried situation.

[0044] like Figures 1 to 9 As shown in the specific embodiment, a feeding plate 241 is also installed on the surface of the synchronous shaft 2. The feeding plate 241 and the pusher plate 24 are located at both ends of the drying chamber 12, respectively. A synchronous frame 242 is installed on the feeding plate 241, and the other end of the synchronous frame 242 is connected to the pusher plate 24. The synchronous frame 242 is used to drive the feeding plate 241 and the pusher plate 24 to move synchronously. The feeding plate 241 is used to push the quartz ore towards the pusher plate 24. The synchronous frame 242 realizes the linkage between the actions of the feeding plate 241 and the pusher plate 24. The feeding plate 241 can continuously convey the ore away from the air inlet pipe 122 towards the pusher plate 24, ensuring the orderly flow of ore in the drying chamber 12, avoiding the situation of one side piling up and the other side being empty, and improving the space utilization of the equipment.

[0045] like Figures 1 to 9 As shown, the turntable 22 and the insert rod 25 are connected through each other. A slide rod 251 is installed at the end of the insert rod 25, and the slide rod 251 is slidably mounted on the side wall of the guide plate 252. A connecting frame 253 is installed at the bottom of the guide plate 252, and the bottom of the connecting frame 253 is connected to the side wall of the drying chamber 12. A ramp is provided at the connection between the protrusion 254 and the guide plate 252. A tension spring 256 is installed on the outer wall of the insert rod 25 located outside the drying chamber 12. A baffle 255 is installed on the insert rod 25. One end of the tension spring 256 is engaged with the baffle 255, and the other end of the tension spring 256 is engaged with the positioning sleeve 222. The cooperation between the slide rod 251 and the guide plate 252 reduces the sliding resistance of the insert rod 25, ensuring smooth operation. The ramp design of the protrusion 254 facilitates the smooth triggering of the insert rod 25. The cooperation between the tension spring 256 and the baffle 255 enables the automatic reset of the insert rod 25 after triggering, ensuring the cyclic reliability of the pushing action and reducing the probability of mechanical jamming.

[0046] like Figures 1 to 9 As shown, further, a discharge port 262 is provided at the bottom of the drying chamber 12 near the pusher plate 24. A sealing door 26 is slidably provided on the discharge port 262, and a push rod 261 is installed on the sealing door 26. When the pusher plate 24 moves, the push rod 261 is squeezed to drive the sealing door 26 to separate from the discharge port 262. A push rod 263 is installed at the bottom of the sealing door 26, and a push plate 264 is installed at the end of the push rod 263. A limit seat 266 is slidably provided on the push rod 263. The limit seat 266 is installed on the side wall of the drying chamber 12. A limit spring 265 is sleeved on the push rod 263. One end of the limit spring 265 is engaged with the side wall of the push plate 264, and the other end of the limit spring 265 is engaged with the limit seat 266. The bottom of the discharge port 262 corresponds to the receiving hopper 267 installed on the operating table 1. The pusher plate 24 and the extrusion rod 261 enable the sealing door 26 to open automatically without additional power, saving energy. The limit spring 265 can drive the sealing door 26 to reset in time after unloading, avoiding the leakage of high-temperature gas during the drying process and reducing energy waste. The receiving hopper 267 can collect the dried ore in a concentrated manner, which is convenient for subsequent transportation.

[0047] Example 3, based on the above examples and the differences between this example and the following: Figures 1 to 9As shown, a fixed seat 313 is movably inserted into the lifting rod 311. The fixed seat 313 is installed on the side wall of the drying chamber 12. A ball bearing 312 is installed at the bottom of the lifting rod 311, and the ball bearing 312 corresponds to the operating table 1. A pressure plate 31 is installed at the top of the lifting rod 311, and the pressure plate 31 fits against the lower surface of the cam 3. A return spring 314 is sleeved on the lifting rod 311. One end of the return spring 314 is engaged with the fixed seat 313, and the other end of the return spring 314 is engaged with the pressure plate 31. The fixed seat 313 provides vertical guidance for the lifting rod 311, ensuring its precise up and down movement; the ball bearing 312 reduces frictional wear between the lifting rod 311 and the operating table 1, extending the service life of the components; the return spring 314 cooperates with the pressure plate 31 to ensure that the lifting rod 311 returns to its original position in time when the cam 3 rotates, ensuring the accuracy and smoothness of the angle adjustment of the drying chamber 12.

[0048] The implementation principle of the quartz ore washing and drying line of the present invention is as follows:

[0049] The operator first places the equipment on a level surface, then opens the feed door 125 and feeds in the quartz ore to be dried. Next, the operator closes the feed door 125 completely. At this point, the overall state of the equipment is as follows: Figure 9 As shown, the thickness of the quartz ore on the side closer to the air inlet pipe 122 is lower than that on the other side.

[0050] Next, the operator needs to connect the air inlet pipe 122 to the high-temperature gas delivery system. At this time, the high-temperature gas flows in the drying chamber 12, which can dry the quartz ore inside. Since the thin part of the quartz ore is located at the air inlet, it can be heated better at this time, thus improving the drying efficiency.

[0051] Next, the operator starts the drive motor 21. After the drive motor 21 starts, it drives the synchronous shaft 2 to rotate. When the synchronous shaft 2 rotates, the coaxially connected cam 3 rotates accordingly. The cam 3 is in contact with the pressure plate 31 at the top of the lifting rod 311, pushing the pressure plate 31 to make the lifting rod 311 slide on the fixed seat 313 (the bottom ball bearing 312 reduces friction with the operating table 1), and the return spring 314 is compressed. When the cam 3 rotates to the non-protruding part, the return spring 314 returns to its original position, pulling the pressure plate 31 and the lifting rod 311 back to their original position. The reciprocating motion of the lifting rod 311 changes the angle of the drying box 12. When the drying box 12 is in a horizontal state, the ore can slide to a thinner and easier-to-dry area.

[0052] During this process, the spirally distributed stirring rods 23 and the inclined stirring plates 231 on the synchronous shaft 2 rotate synchronously to stir the quartz ore in the drying box 12, break the ore accumulation state, increase the contact area between the ore and the high-temperature gas, and improve the drying uniformity and efficiency.

[0053] Meanwhile, the feeding plate 241 on the surface of the synchronous shaft 2 moves synchronously with the pusher plate 24 under the drive of the synchronous frame 242. The feeding plate 241 continuously pushes the quartz ore away from the air inlet pipe 122 toward the pusher plate 24, so as to realize the orderly conveying of ore.

[0054] When the pusher plate 24 rotates downward with the synchronous shaft 2, it will block some of the quartz ore; at this time, the slide bar 251 at the end of the insert rod 25 slides on the side wall of the guide plate 252, and the insert rod 25 contacts the sloping protrusion 254 on the guide plate 252. Under the action of the sloping protrusion 254, the insert rod 25 moves to the outside of the drying box 12, and the tension spring 256 is stretched (the baffle 255 moves with the insert rod 25). The insert rod 25 drives the pusher plate 24 to move, pushing the dried quartz ore near the air inlet pipe 122 towards the discharge port 262.

[0055] As the pusher plate 24 moves, it presses against the top rod 261 on the sealing door 26. The top rod 261 drives the sealing door 26 to slide along the discharge port 262, causing the sealing door 26 to separate from the discharge port 262. The dried quartz ore falls from the discharge port 262 into the receiving hopper 267. When the pusher plate 24 leaves the top rod 261, the limit spring 265 resets, pulling the push rod 263 and the push plate 264, causing the sealing door 26 to re-close the discharge port 262, completing one discharge. Then, when resetting, the operator needs to reopen the feed door 125 to replenish new quartz ore.
