Description

Technical Field

[0001] This invention relates to a conveying device, specifically a mixing and conveying device for mineral powder production, belonging to the field of mineral powder production technology. Background Technology

[0002] In industrial production, mineral powder, as an important industrial raw material, is widely used in various industries such as construction, metallurgy, and chemicals. The production process of mineral powder typically involves crushing, grinding, and subsequent processing of the ore to obtain mineral powder products that meet specific particle size requirements and quality standards. In this production process, the mixing and conveying device plays a crucial role. It is responsible for uniformly mixing materials of different compositions or particle sizes and efficiently conveying them to the next production stage, thereby ensuring the quality of the mineral powder products and production efficiency.

[0003] However, existing mixing and conveying devices for mineral powder production generally have some problems in the discharge process after material mixing. Specifically, most of these devices rely on the natural fall of materials to achieve discharge. This method may be able to handle materials with good flowability, but it is inadequate when dealing with fine and easily adherent materials such as mineral powder. Mineral powder easily adheres to the inner wall of the pipeline and can easily cause agglomeration and blockage during discharge.

[0004] Therefore, developing a mixing and conveying device for mineral powder production that can overcome the above defects has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a mixing and conveying device for mineral powder production. The device has a simple structure and effectively reduces the possibility of mineral powder adhesion or agglomeration.

[0006] To solve the above technical problems, the present invention provides a mixing and conveying device for mineral powder production, including a horizontally arranged frame, on which a mixing mechanism and a conveying mechanism are arranged in sequence, and the conveying mechanism is connected to the mixing mechanism; the mixing mechanism includes a mixing box fixedly connected to the frame, a feed pipe at the top of the mixing box, a discharge pipe on one side of the bottom, a control valve on the discharge pipe, a first stirring assembly inside the mixing box, and a dehumidification assembly outside the mixing box; the conveying mechanism includes a conveying cylinder, which is inclined to form a top and a bottom, a feed inlet at the top of the conveying cylinder that communicates with the discharge pipe of the mixing mechanism, a discharge outlet at the bottom of the conveying cylinder, a second stirring assembly inside the conveying cylinder, and an anti-blocking rotating head at one end of the second stirring assembly that penetrates through the discharge outlet at the bottom of the conveying cylinder.

[0007] This invention employs a first stirring component in the mixing mechanism for initial stirring and dispersing. More specifically, two sets of first stirring components are used to achieve better, more comprehensive, and thorough stirring, keeping the mineral powder in a loose state during the mixing process. This prevents some mineral powder from agglomerating and adhering to the inner wall of the mixing tank or clumping due to uneven stirring, improving the uniformity and flowability of the mineral powder during the mixing stage. This lays a good foundation and reduces the possibility of adhesion or clumping during subsequent conveying. Since mineral powder is prone to adhesion or clumping in humid environments, a dehumidifying component is incorporated into the mixing mechanism to remove moisture from the air. A conveying mechanism is also included, with a second stirring component in the conveying mechanism for further stirring and dispersing, ensuring flowability. An anti-clogging rotating head is installed at the discharge port to more effectively stir and disperse the mineral powder near the discharge port, further preventing clumping due to localized accumulation at the outlet. This ensures smooth discharge of the mineral powder and reduces the risk of adhesion or clumping at the conveyor outlet. The technical solutions of this invention are progressive and combined, each indispensable, and these synergistic technologies together constitute the core of this invention's solution to the problems of adhesion and clogging.

[0008] The technical solution further defined in this invention is: Furthermore, in the aforementioned mixing and conveying device for mineral powder production, two first stirring components are vertically arranged inside the mixing box, and the two first stirring components are located on both sides of the feed pipe.

[0009] Technical effect: By adopting the above technical solution, two first stirring components are set in the mixing box. The stirring force of a single stirring component is limited. By using two stirring components, the mineral powder in the mixing box can be stirred and dispersed to a greater extent, and problems such as sticking and clumping can be better avoided.

[0010] Furthermore, in the aforementioned mixing and conveying device for mineral powder production, the first stirring assembly includes a first stirring motor disposed at the top of the outer wall of the mixing tank. The output shaft of the first stirring motor passes through the mixing tank and is disposed inside the mixing tank. A first stirring fan blade is fixedly connected to its outer periphery along the length direction of the output shaft of the first stirring motor. The first stirring fan blade is spiral in shape.

[0011] Technical effect: By adopting the above technical solution, a first stirring component, namely a combination of a first stirring motor and a first stirring fan blade, is set in the mixing box. This component can effectively stir the mineral powder in the mixing box, keeping the mineral powder in a loose state during the mixing process. This prevents some mineral powder from agglomerating and adhering to the inner wall of the mixing box or clumping due to uneven stirring.

[0012] Furthermore, in the aforementioned mixing and conveying device for mineral powder production, the dehumidification component includes a circulation pipe. One end of the circulation pipe is connected to one side of the top of the mixing box via an air pump, and the other end of the circulation pipe is connected to the bottom of the mixing box. A dehumidification element is provided on the circulation pipe.

[0013] Technical effect: By adopting the above technical solution, a dehumidification component is installed outside the mixing box. Since mineral powder is prone to adhesion or clumping in a humid environment, the air pump makes the air in the mixing box circulate in the circulation pipe. The dehumidification component (dehumidifier) ​​can remove the moisture in the air and reduce the humidity in the mixing box. This can reduce the possibility of mineral powder adhering to the inner wall of the mixing box or clumping due to moisture, and ensure the quality of mineral powder during the mixing and transportation process.

[0014] Furthermore, in the aforementioned mixing and conveying device for mineral powder production, the dehumidifying component is a dehumidifier, both ends of which are connected to the circulation pipe, and a drain pipe is installed at the bottom of the dehumidifier.

[0015] Furthermore, the aforementioned mixing and conveying device for mineral powder production also includes a heating element, which is installed on the circulation pipe.

[0016] Technical effect: The above technical solution is equipped with a heating element, which works in conjunction with the dehumidification component. The dehumidification component (dehumidifier) ​​can remove moisture from the air, and the heating element (multiple electric heating grids evenly distributed in the circulation pipe) can heat the air, thereby better reducing the humidity in the mixing box and reducing the possibility of mineral powder adhering to the inner wall of the mixing box or clumping due to moisture, thus ensuring the quality of mineral powder during the mixing and conveying process.

[0017] Furthermore, in the aforementioned mixing and conveying device for mineral powder production, the heating element consists of multiple electric heating grids installed inside the circulation pipe, with the multiple electric heating grids evenly distributed inside the circulation pipe.

[0018] Furthermore, in the aforementioned mixing and conveying device for mineral powder production, the second stirring assembly includes a second stirring motor located outside the conveying cylinder at the top of the conveying cylinder. The output shaft of the second stirring motor passes through the central axis of the conveying cylinder and is fixedly connected to a spiral second stirring blade. The edge of the second stirring blade slides against the inner wall of the conveying cylinder. An anti-clogging rotating head is provided at one end of the output shaft of the second stirring motor located on the second stirring blade.

[0019] Technical effect: By adopting the above technical solution, a second stirring component is provided in the conveying mechanism. The second stirring component is provided with a second stirring fan blade, which restricts the edge of the fan blade to slide against the inner wall of the conveying cylinder. When the fan blade rotates under the drive of the second stirring motor, it can fully stir the mineral powder in the conveying cylinder to the greatest extent, and prevent the mineral powder from adhering to the inner wall of the conveying cylinder due to prolonged stillness or uneven force during the conveying process.

[0020] Furthermore, in the aforementioned mixing and conveying device for mineral powder production, the anti-clogging rotating head includes an extension rod, one end of which is fixedly connected to a cone, and multiple stirring blades are uniformly and circumferentially fixed on the surface of the cone.

[0021] Preferably, an annular gap of 0.5 to 2 mm is left between the outer edge of the stirring plate and the inner wall of the discharge port to avoid wear and jamming of the parts while rotating and dispersing the mineral powder.

[0022] Technical effect: By adopting the above technical solution and setting a specific anti-clogging rotating head, the stirring blades can more effectively stir and disperse the mineral powder near the discharge port when the anti-clogging rotating head is rotating, further preventing the mineral powder from clumping due to local accumulation at the outlet, ensuring that the mineral powder can be discharged smoothly, and reducing the risk of mineral powder adhering or clumping at the outlet of the conveyor cylinder.

[0023] Furthermore, in the aforementioned mixing and conveying device for mineral powder production, a telescopic liquid cylinder is provided at the end of the extension rod away from the cone. The anti-clogging rotating head is connected to the second stirring assembly through the telescopic liquid cylinder to achieve rotation and extension.

[0024] Technically, by adopting the above technical solution, the output shaft of the second stirring motor is connected to the anti-clogging rotating head via a telescopic hydraulic cylinder. This design allows the anti-clogging rotating head to extend and retract within a certain range. During the stirring and conveying of mineral powder, the telescopic movement of the anti-clogging rotating head further enhances the stirring and dispersing effect on the mineral powder, especially at the outlet of the conveying cylinder, better preventing adhesion or agglomeration and ensuring smooth conveying of the mineral powder.

[0025] The beneficial effects of this invention are: This invention addresses the problems of adhesion, agglomeration, or blockage encountered during the mineral powder production process, from feeding and mixing to subsequent conveying. Through a synergistic technology system integrating the two major processes of mixing and conveying, it systematically solves this complex problem of adhesion, agglomeration, and blockage throughout the mixing and conveying stages. The specific effects of the technical solution are as follows: (1) The first stirring component reduces the adhesion or agglomeration of mineral powder: The first stirring component in the mixing mechanism includes a first stirring motor and a spiral first stirring fan blade. There are two first stirring components, which are respectively set on both sides of the mixing box. The two first stirring components work at the same time, which can stir the mineral powder in the mixing box in all directions and fully, so that the mineral powder remains loose during the mixing process. This avoids the accumulation of some mineral powder due to uneven stirring, which causes it to adhere to the inner wall of the mixing box or agglomerate. This improves the uniformity and fluidity of the mineral powder during the mixing stage and reduces the possibility of adhesion or agglomeration during subsequent transportation.

[0026] (2) Dehumidification components reduce mineral powder adhesion or agglomeration: The dehumidification components include a circulation pipe, an air pump, and dehumidification parts, with a matching heating element designed later. The two ends of the circulation pipe are connected to the top and bottom of the mixing chamber, respectively. The air pump circulates the air in the mixing chamber through the circulation pipe. The dehumidification parts (dehumidifier) ​​remove moisture from the air, and the heating elements (multiple electric heating grids evenly distributed in the circulation pipe) heat the air, reducing the humidity in the mixing chamber. Since mineral powder is prone to adhesion or agglomeration in humid environments, reducing the humidity in the mixing chamber through the dehumidification components can reduce the possibility of mineral powder adhering to the inner wall of the mixing chamber or agglomerating due to moisture, ensuring the quality of the mineral powder during mixing and transportation.

[0027] (3) The second stirring mechanism reduces the adhesion, clumping, or blockage of mineral powder at the discharge port: The second stirring mechanism in the conveying mechanism includes a second stirring motor, a spiral second stirring blade, and an anti-blocking rotating head. The edge of the second stirring blade slides against the inner wall of the conveying cylinder. When it rotates under the drive of the second stirring motor, it can fully stir the mineral powder in the conveying cylinder, preventing the mineral powder from adhering to the inner wall of the conveying cylinder due to prolonged stillness or uneven force during the conveying process. At the same time, the anti-blocking rotating head passes through the bottom outlet of the conveying cylinder. Its rotation can prevent the mineral powder from accumulating and clumping at the outlet, ensuring that the mineral powder can be smoothly discharged from the conveying cylinder, reducing the possibility of mineral powder adhering or clumping in the conveying cylinder.

[0028] (4) Special design of the anti-clogging rotary head reduces mineral powder adhesion, agglomeration, or blockage: The anti-clogging rotary head includes an extension rod, a cone head, and multiple stirring blades uniformly fixed on the cone head in a ring. This special design allows the stirring blades to more effectively stir and disperse the mineral powder near the outlet when the anti-clogging rotary head rotates, further preventing the mineral powder from agglomerating due to local accumulation at the outlet, ensuring that the mineral powder can be discharged smoothly, and reducing the risk of mineral powder adhesion or agglomeration at the outlet of the conveyor cylinder.

[0029] (5) The output shaft of the second stirring motor is connected to the anti-clogging rotating head via a telescopic hydraulic cylinder to reduce mineral powder adhesion, agglomeration, or blockage: This design allows the anti-clogging rotating head to extend and retract within a certain range. During the stirring and conveying of mineral powder, the telescopic movement of the anti-clogging rotating head can further enhance the stirring and dispersing effect of the mineral powder, directly clearing any blockages, especially at the outlet of the conveying cylinder, thus better preventing adhesion or agglomeration and ensuring smooth mineral powder conveying.

[0030] (6) The inclined setting of the conveyor cylinder reduces the adhesion, clumping or blockage of mineral powder: Compared with the horizontal setting in the prior art, which is easy to adhere, the inclined setting uses the gravity of the mineral powder itself and the subsequent stirring to make the mineral powder move more smoothly from the top to the bottom of the conveyor cylinder, reducing adhesion and blockage.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be considered as limitations on this application. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application. Unless otherwise defined, all technical and scientific terms used in the embodiments of this application have the same meaning as commonly understood by those skilled in the art. The terminology used in the embodiments of this application is for the purpose of describing the embodiments of this application only and is not intended to limit this application. Example 1

[0034] In a typical implementation, the conveying mechanism is horizontally arranged on one side of the mixing mechanism, or the feeding, mixing and conveying are arranged sequentially from top to bottom, and a separate stirring component is generally provided in the mixing mechanism.

[0035] See Figure 1 As shown, this embodiment provides a mixing and conveying device for mineral powder production, including a frame 1. The frame 1 is provided with a mixing mechanism 2 and a conveying mechanism 3 connected in sequence. It not only adds a stirring component to the mixing mechanism to enhance the mixing effect, but also adds a dehumidifying component to further prevent adhesion. The position of the conveying mechanism is adjusted to be inclined to facilitate smooth material discharge and prevent adhesion. At the same time, an anti-clogging rotating head is added to the stirring component in the conveying mechanism to prevent adhesion, agglomeration or blockage. It systematically solves the complex problem of adhesion, agglomeration and blockage during mixing and conveying.

[0036] Specifically, see Figure 1 and 2 As shown, the core innovation of the mixing and conveying device for mineral powder production provided in this embodiment lies in the setting of a mixing mechanism 2. The purpose of this mechanism is to thoroughly and comprehensively stir the mineral powder in the mixing box, so that the mineral powder remains in a loose state during the mixing process. This avoids the accumulation of some mineral powder due to uneven stirring, which would cause it to adhere to the inner wall of the mixing box or clump. This improves the uniformity and flowability of the mineral powder during the mixing stage and reduces the possibility of adhesion or clumping during subsequent conveying. The mixing mechanism includes a mixing box 201. The top of the mixing box 201 is provided with a feed pipe 202, and the bottom side is provided with a discharge pipe 203. The discharge pipe 203 is provided with a control valve 204. The mixing box 201 is provided with a first stirring component 26, and the mixing box 201 is also provided with a dehumidification component 27.

[0037] In a preferred embodiment, see [reference] Figure 2 As shown, two first stirring components 26 are vertically arranged inside the mixing chamber 201. The two first stirring components 26 are located on both sides of the feed pipe 202. The first stirring component 26 includes a first stirring motor 261 set at the top of the outer wall of the mixing chamber 201. The output shaft of the first stirring motor 261 passes through the mixing chamber 201 and is fixedly connected to a spiral first stirring fan blade 262. Two first stirring components are arranged inside the mixing chamber. The stirring force of a single stirring component is limited. By using two stirring components, the mineral powder in the mixing chamber can be stirred and dispersed to a greater extent, and problems such as adhesion and agglomeration can be better avoided.

[0038] In a preferred embodiment, see [reference] Figure 2As shown, the dehumidification component 27 includes a circulation pipe 271. One end of the circulation pipe 271 is connected to one side of the top of the mixing box 201 via an air pump 272, and the other end of the circulation pipe 271 is connected to the bottom of the mixing box 201. A dehumidification component 273 is provided on the circulation pipe 271. The dehumidification component is provided outside the mixing box. Since mineral powder is prone to adhesion or clumping in a humid environment, the air pump makes the air in the mixing box circulate in the circulation pipe. The dehumidification component can remove moisture from the air and reduce the humidity in the mixing box. This can reduce the possibility of mineral powder adhering to the inner wall of the mixing box or clumping due to moisture, and ensure the quality of mineral powder during the mixing and conveying process.

[0039] In a preferred embodiment, see [reference] Figure 2 As shown, the circulation pipe 271 is equipped with a heating element 5. The heating element works in conjunction with the dehumidification component in front. The dehumidification component can remove moisture from the air, and the heating element can heat the air, thereby reducing the humidity in the mixing box and reducing the possibility of mineral powder adhering to the inner wall of the mixing box or clumping due to moisture, thus ensuring the quality of mineral powder during the mixing and conveying process.

[0040] See Figure 1 As shown, another core innovation of the mixing and conveying device for mineral powder production provided in this embodiment is the setting of a conveying mechanism 3. The purpose is to utilize the gravity of the mineral powder itself, combined with the stirring thrust of the second stirring component, and under the action of the anti-blocking rotating head, to enable the mineral powder to move from the top to the bottom of the conveying cylinder and be smoothly discharged at the discharge port, effectively reducing the possibility of adhesion, agglomeration and blockage during the conveying process. The conveying device includes a conveying cylinder 301, which is inclined to form a top and a bottom. The top of the conveying cylinder is provided with an inlet that communicates with the discharge pipe 203 of the mixing mechanism 2, and the bottom of the conveying cylinder is provided with a discharge port. The second stirring component 32 is provided inside the conveying cylinder 301, and an anti-blocking rotating head 4 is provided at one end of the second stirring component 32. The anti-blocking rotating head 4 passes through the discharge port at the bottom of the conveying cylinder.

[0041] In a preferred embodiment, see [reference] Figure 1 and 3As shown, the second stirring assembly 32 includes a second stirring motor 321 located outside the conveying cylinder 301 at the top of the conveying cylinder. The output shaft of the second stirring motor 321 passes through the central axis of the conveying cylinder 301 and is fixedly connected to a spiral second stirring blade 322. The edge of the second stirring blade 322 slides against the inner wall of the conveying cylinder 301. An anti-clogging rotating head 4 is provided at one end of the output shaft of the second stirring motor 321 located at the second stirring blade 322. The second stirring assembly is provided in the conveying mechanism, and the second stirring blade is provided in the second stirring assembly to restrict its edge from sliding against the inner wall of the conveying cylinder. When rotating under the drive of the second stirring motor, it can fully stir the mineral powder in the conveying cylinder to the greatest extent, and prevent the mineral powder from adhering to the inner wall of the conveying cylinder due to long-term stillness or uneven force during the conveying process.

[0042] In a preferred embodiment, see [reference] Figure 4 As shown, the anti-clogging rotating head 4 includes an extension rod 401, one end of which is fixedly connected to a cone head 402. Multiple stirring blades 403 are uniformly and annularly fixed on the surface of the cone head 402. A 0.5-2mm annular gap is left between the outer edge of the stirring blades and the inner wall of the discharge port. While rotating and dispersing the mineral powder, the rotating head avoids wear and jamming of the components. The anti-clogging rotating head with a specific structure allows the stirring blades to more effectively stir and disperse the mineral powder near the discharge port when the rotating head is rotating. This further prevents the mineral powder from clumping due to local accumulation at the outlet, ensuring that the mineral powder can be discharged smoothly and reducing the risk of mineral powder adhering or clumping at the outlet of the conveyor cylinder.

[0043] In a preferred embodiment, see [reference] Figure 5 As shown, to ensure maximum unobstructed flow at the discharge port and prevent blockage, the anti-blocking rotating head is connected to the output shaft of the second stirring motor via a telescopic hydraulic cylinder. Specifically, a telescopic hydraulic cylinder 404 is provided at the end of the extension rod 401 away from the cone head 402. The anti-blocking rotating head 4 is connected to the second stirring assembly 32 via the telescopic hydraulic cylinder 404, enabling rotation and telescopic movement. The output shaft of the second stirring motor is connected to the anti-blocking rotating head via the telescopic hydraulic cylinder. This design allows the anti-blocking rotating head to extend and retract within a certain range. During the stirring and conveying of mineral powder, the telescopic movement of the anti-blocking rotating head can further enhance the stirring and dispersion effect of the mineral powder, especially at the outlet of the conveying cylinder, better preventing adhesion or agglomeration and ensuring smooth conveying of the mineral powder.

[0044] The following will be combined with the appendix Figure 1 -Appendix Figure 5 This invention provides a complete description of a specific embodiment of the invention. Unless otherwise specified, the stirring motor, stirring fan blade, dehumidifier, heating element, air pump, telescopic liquid cylinder, control valve, etc. involved in the embodiments of the invention are all known in the art and can be obtained by commercial purchase or by processing using processes known in the art.

[0045] In a more specific implementation plan, see Figure 1 As shown, this embodiment provides a mixing and conveying device for mineral powder production, including a horizontally arranged frame. The mixing mechanism is mounted on the frame via supports, and the conveying mechanism is inclinedly mounted on the frame via multiple supports. The conveying mechanism is located on one side of the mixing mechanism. The frame 1 integrates the mixing mechanism and the conveying mechanism in sequence, realizing a continuous process from mixing to conveying of mineral powder. Through the synergistic technology system of the two major processes of mixing and conveying, the complex problem of adhesion, agglomeration and blockage during mixing and conveying is systematically solved.

[0046] For details, please refer to Figure 1 and 2 As shown, the mixing mechanism 2 includes a mixing box 201 fixedly connected to the frame via a bracket. The bracket suspends the mixing box in the air. To facilitate feeding the inclined conveyor cylinder, a feed pipe 202 is provided at the top center of the mixing box 201, and a discharge pipe 203 is provided on the bottom side where the conveyor mechanism is located. A control valve 204 is provided on the discharge pipe 203. The control valve is preferably a solenoid valve, such as a DMF-Z-25 type solenoid pulse valve with a working voltage of DC24V. The solenoid valve controls the opening and closing of the valve 204 by electromagnetic force. When it is necessary to discharge mineral powder from the mixing box 201, the solenoid valve is energized, and the electromagnetic force causes the valve to open, allowing the mineral powder to enter the conveyor mechanism through the discharge pipe 203. When it is not necessary to discharge, the solenoid valve is de-energized, and the valve closes under the action of a spring or other reset mechanism, preventing the mineral powder from flowing out. The use of the solenoid valve can... To achieve automated control of material discharge and improve the convenience and accuracy of operation, the solenoid valve can be directly connected to existing PLC, microcontroller and other control systems. Controlled by electrical signals, it is easy to integrate into remote control, logic interlock or timing control systems, and easy to achieve automated control. It can open or close within milliseconds, quickly cut off or adjust materials, and has a fast response speed. Two first stirring components 26 are vertically installed in the mixing box 201. The two first stirring components work simultaneously, which can stir the mineral powder from two different positions in the mixing box 201, further expanding the stirring range and enhancing the stirring effect. The stirring action on both sides works together to avoid stirring dead corners, so that the mineral powder in the mixing box 201 is more comprehensive and more fully mixed, ensuring the quality and performance stability of the mineral powder, and providing a good foundation for subsequent conveying and processing.

[0047] The specific structure of the first stirring component 26 is described in detail. For details, please refer to... Figure 2As shown, the first stirring assembly 26 includes a first stirring motor 261 disposed on the top of the outer wall of the mixing chamber 201. Two first stirring motors are located on both sides of the feed pipe. The output shaft of the first stirring motor 261 passes through the mixing chamber 201 and is disposed inside the mixing chamber. A spiral first stirring blade 262 is fixedly connected from top to bottom along the length direction of the outer periphery of the output shaft of the first stirring motor. When the first stirring motor 261 is started, the output shaft drives the spiral first stirring blade 262 to rotate. During the rotation, the spiral first stirring blade 262 can generate axial and radial stirring effects on the mineral powder in the mixing chamber 201. Axial stirring causes the mineral powder to flow in the vertical direction, promoting the mixing of mineral powder at different height levels; radial stirring causes the mineral powder to be evenly distributed in the horizontal direction, ensuring that the mineral powder in all parts of the mixing chamber 201 can be fully mixed, improving the uniformity of mineral powder mixing.

[0048] The specific construction of the dehumidification unit 27 is described in detail. For details, please refer to... Figure 2 As shown, the dehumidification assembly 27 includes a circulation pipe 271 disposed outside the mixing chamber 201. One end of the circulation pipe 271 is connected to one side of the top of the mixing chamber 201 via an air pump 272, and the other end of the circulation pipe 271 is connected to the bottom of the mixing chamber 201. A dehumidifier is mounted on the circulation pipe 271, with both ends of the dehumidifier connected to the circulation pipe 271. A drain pipe 274 is located at the bottom of the dehumidifier. Multiple electric heating grids are evenly distributed inside the circulation pipe 271. The dehumidification assembly forms a closed gas circulation system with the mixing chamber 201 through the circulation pipe 271. The two ends of the circulation pipe are connected to the top and bottom of the mixing chamber 201, respectively. After the air pump 272 is turned on, the mixture... Air inside chamber 201 is drawn into the circulation pipe, processed by a dehumidifier, and then returned to mixing chamber 201. This cycle repeats continuously to reduce humidity within mixing chamber 201, thereby minimizing the possibility of mineral powder adhering or clumping due to moisture. Air pump 272 is the power source for the entire circulation system, providing power for airflow within circulation pipe 271. When air pump 272 operates, it generates negative pressure within the circulation pipe, drawing air from the bottom of mixing chamber 201 into the circulation pipe and propelling it to flow in a predetermined direction. This ensures that the air sequentially passes through the dehumidifier and heating grid for moisture removal and heating. Specifically: Dehumidifiers typically have a refrigeration system or other dehumidification technology inside. When humid air enters the dehumidifier, the water vapor in the air condenses into liquid water inside the dehumidifier. This liquid water is discharged from the circulation system through the drain pipe 274 installed on the dehumidifier, thereby reducing the humidity of the air passing through the dehumidifier. The dehumidified air then re-enters the circulation pipe to continue circulating, further reducing the humidity in the mixing chamber 201. The electric heating network is radially inserted and fixed to the inner wall of the circulation pipe using existing technology, and is evenly distributed along the length of the pipe. The electric heating network is electrically connected to an external power source through pre-embedded wires inside the pipe wall. After being energized, the electric heating network generates heat, which heats the air flowing through it. Heating the air has two main functions: First, the high temperature air can reduce the relative humidity inside the mixing chamber 201, because relative humidity is related to temperature. As the temperature rises, the air's ability to hold water vapor increases, and the relative humidity will decrease. Second, the heated air helps the mineral powder to remain dry, preventing it from absorbing moisture from the air and becoming damp, sticky, or clumpy. The dehumidification and heating technologies complement each other, working together to reduce the humidity inside the mixing chamber. This reduces the likelihood of mineral powder adhering to the inner wall of the mixing chamber or clumping due to moisture, ensuring the quality of the mineral powder during mixing and conveying.

[0049] For details, please refer to Figure 3 As shown, the conveying mechanism 3 includes a conveying cylinder 301 fixedly connected to the frame by a bracket. The conveying cylinder 301 is an inclined cylindrical structure, forming a high and a low end, namely the top and bottom of the conveying cylinder. The top of the conveying cylinder has a feed inlet that communicates with the discharge pipe 203 of the mixing mechanism 2, and the bottom of the conveying cylinder has a discharge outlet. The conveying cylinder 301 is equipped with a second stirring assembly 32. One end of the second stirring assembly 32 is equipped with an anti-blocking rotating head 4, which penetrates the discharge outlet at the bottom of the conveying cylinder. The second stirring assembly fully stirs the mineral powder in the conveying cylinder to prevent the mineral powder from adhering to the inner wall of the conveying cylinder due to prolonged stillness or uneven force during the conveying process. At the same time, the anti-blocking rotating head penetrates the bottom outlet of the conveying cylinder, and its rotation can prevent the mineral powder from accumulating and agglomerating at the outlet, ensuring that the mineral powder can be smoothly discharged from the conveying cylinder and reducing the possibility of mineral powder adhering or agglomerating in the conveying cylinder.

[0050] The specific structure of the second stirring component 32 is described in detail. For details, please refer to... Figure 3As shown, the second stirring assembly 32 includes a second stirring motor 321 located outside the conveying cylinder 301 at the top of the conveying cylinder 301. The output shaft of the second stirring motor 321 passes through the central axis of the conveying cylinder 301. A spiral second stirring blade 322 is fixedly connected to the outer periphery of the output shaft of the second stirring motor 321. The second stirring motor 321 drives the spiral second stirring blade 322 to rotate. The edge of the second stirring blade 322 slides against the inner wall of the conveying cylinder 301, stirring the mineral powder inside the conveying cylinder 301 during rotation, so that the mineral powder remains loose during the conveying process. To prevent mineral powder from adhering to the inner wall of the conveying cylinder 301 due to stillness or uneven force, the output shaft of the second stirring motor 321 extends to the bottom of the conveying cylinder, and an anti-blocking rotating head is fixedly installed at this end. The anti-blocking rotating head passes through the bottom discharge port of the conveying cylinder. The anti-blocking rotating head 4 is located at one end of the second stirring fan blade 322. When the second stirring fan blade 322 rotates, the anti-blocking rotating head 4 also rotates. Its function is to prevent mineral powder from accumulating and agglomerating at the bottom discharge port of the conveying cylinder 301, ensuring that the mineral powder can be smoothly discharged from the conveying cylinder 301, and ensuring the continuity and stability of the entire conveying process.

[0051] In one alternative implementation, see [reference] Figure 4 As shown, the anti-clogging rotating head 4 includes an extension rod 401, with a cone 402 fixedly connected to one end of the extension rod 401. Multiple stirring blades 403 are uniformly and circumferentially fixed on the surface of the cone 402. A 1mm annular gap is left between the outer edge of the stirring blades and the inner wall of the discharge port. This design prevents wear and jamming of components while rotating and dispersing the mineral powder, allowing the anti-clogging rotating head to pass smoothly through the discharge port. When the second stirring mechanism operates, the anti-clogging rotating head 4 rotates accordingly. The extension rod 401 provides connection and support, enabling the cone 402 and stirring blades 403 to penetrate deep into the bottom discharge port area of ​​the conveying cylinder 301. The design of the cone 402 helps reduce the resistance encountered by the anti-clogging rotating head 4 during rotation and better guides the flow of mineral powder. The multiple annularly distributed stirring blades 403, when rotating, thoroughly stir and disperse the mineral powder near the bottom outlet of the conveying cylinder 301. Since mineral powder tends to accumulate at the discharge port during the conveying process, the stirring action of the stirring plate 403 can disrupt the stable structure formed by the accumulation of mineral powder, prevent the mineral powder from clumping and blocking at this point, and ensure that the mineral powder can be smoothly discharged from the bottom outlet of the conveying cylinder 301, avoiding the impact of the entire conveying process due to outlet blockage.

[0052] Furthermore, to ensure that the anti-clogging rotary head 4 can better prevent clogging and reduce the possibility of adhesion or agglomeration, the anti-clogging rotary head 4 is connected to the output shaft of the second stirring motor via an existing telescopic hydraulic cylinder, see [reference]. Figure 5As shown, specifically, a telescopic hydraulic cylinder 404 is provided at the end of the extension rod 401 away from the cone head 402. The anti-blocking rotating head 4 is connected to the output shaft of the second stirring motor through the telescopic hydraulic cylinder 404. During the operation of the conveying mechanism, the second stirring motor 321 drives the second stirring fan blade 322 to rotate, which in turn drives the anti-blocking rotating head 4 to rotate synchronously, so as to stir and prevent blockage of the mineral powder in the conveying cylinder 301. The presence of the telescopic hydraulic cylinder 404 enables the anti-blocking rotating head 4 to extend and retract in the axial direction (i.e., along the length direction of the conveying cylinder 301). When encountering the accumulation or blockage of mineral powder at the bottom outlet of the conveying cylinder 301, the telescopic hydraulic cylinder 404 can drive the anti-blocking rotating head 4 to extend towards the discharge port, increase the stirring and dispersion of mineral powder near the discharge port, more effectively destroy the structure formed by the accumulation of mineral powder, prevent the mineral powder from agglomerating at the outlet, and ensure that the mineral powder can be discharged smoothly from the conveying cylinder 301.

[0053] In practice, S101, the mineral powder enters the mixing box 201 through the feed pipe 202. Inside the mixing box 201, mixing and dehumidification are completed in cooperation with the first stirring component and the dehumidification component. Specifically: The first stirring component stirs the mineral powder entering the mixing box 201, so that the mineral powders of different components are fully and evenly mixed, avoiding local unevenness of components and ensuring the quality stability of the mineral powder. The air pump in the dehumidification unit circulates the air in the mixing chamber through the circulation pipe. The dehumidification component removes moisture from the air and reduces the humidity in the mixing chamber 201. Because a humid environment can cause mineral powder to easily adhere to the inner wall of the mixing chamber 201 or clump together, the dehumidification process keeps the mineral powder in a relatively dry state, reducing the possibility of adhesion or clumping during the mixing process and facilitating subsequent transportation.

[0054] S102. By controlling the opening of the control valve 204 on the discharge pipe 203, the mineral powder can be discharged from the mixing box 201 and enter the conveying cylinder 301.

[0055] S103. Inside the conveying cylinder 301, due to its inclined setting, it uses its own weight in conjunction with the second stirring component and the anti-clogging rotating head to further stir and push to the designated position, moving from the top of the conveying cylinder to the bottom and exiting from the discharge port.

[0056] The mixing and conveying device of the present invention effectively reduces the possibility of mineral powder adhesion or agglomeration, ensures conveying efficiency, reduces cleaning trouble, and thus saves costs.

[0057] In addition to the embodiments described above, the present invention may have other implementations. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by the present invention.
