Description

Technical Field

[0001] This utility model relates to the field of industrial waste treatment technology, and more specifically to a cold pressing molding device for treating industrial blast furnace dust. Background Technology

[0002] During the blast furnace smelting process in industrial production, a large amount of smoke and dust is continuously generated. This smoke and dust not only contains a large number of dust particles, but also contains iron oxides, carbon slag, and other substances. Direct emission will cause air pollution, while indiscriminate accumulation will easily lead to secondary dust pollution due to wind diffusion, and also waste the recyclable resources in the smoke and dust. Currently, the mainstream treatment method for blast furnace smoke and dust in the industry is to collect it first and then solidify it for subsequent transportation, storage, or resource utilization (such as as building aggregate, roadbed filler, etc.). Among these methods, cold pressing has become a commonly used forming process due to its advantages of not requiring high-temperature heating and low energy consumption.

[0003] However, existing cold-pressing molding equipment for industrial blast furnace dust still has many technical drawbacks in practical applications: First, the feeding process often uses natural discharge or simple conveying structures, which can easily lead to pipe blockage due to uneven particle size and poor flowability, resulting in feeding interruptions and the inability to achieve uniform feeding, thus affecting the subsequent molding quality. Second, when cold-pressing dust, the direct extrusion method is used, and there is a lack of effective bonding between the dust raw materials, resulting in a loose material structure with insufficient strength after molding. This makes the material prone to breakage and scattering during subsequent handling or use, reducing the reliability of resource utilization. Third, the molded material usually needs to be manually removed from the mold, which not only increases the labor intensity of operators but also poses safety hazards due to mold temperature or sharp edges. Furthermore, manual material removal is inefficient and affects the continuity of the overall processing flow.

[0004] In view of this, the present invention proposes a cold pressing forming device for industrial blast furnace dust treatment to solve this problem. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cold pressing forming device for industrial blast furnace dust treatment, so as to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a cold pressing forming device for industrial blast furnace dust treatment, including a base, wherein a feeding mechanism, an adding mechanism and a forming mechanism are respectively provided on the upper surface of the base; The feeding mechanism includes a feeding pipe fixedly installed above the base, a feeding hopper fixedly connected to the upper left of the feeding pipe, a spiral auger blade rotatably connected to the inner wall of the feeding pipe, a reduction motor for driving the spiral auger blade to rotate fixedly installed at the left end of the feeding pipe, and a discharge pipe embedded at the right end of the feeding pipe. The adding mechanism includes a liquid storage tank fixedly installed on the surface of the base. The liquid storage tank contains adhesive. A delivery pump is provided on the front bottom side of the liquid storage tank. The inlet end of the delivery pump extends into the interior of the liquid storage tank. The outlet end of the delivery pump is fixedly connected to a delivery pipe. Several connecting pipes are equidistantly embedded on the surface of the delivery pipe. The other end of the connecting pipe extends to the top of the inner cavity of the feed pipe. The forming mechanism includes a support platform fixedly installed on the surface of the base. A forming frame is provided on the top of the support platform. The upper opening of the forming frame corresponds to the position of the discharge pipe of the feed pipe. A top frame is fixedly installed on the top of the support platform. A hydraulic push rod is embedded in the surface of the top frame. The hydraulic push rod is connected to the external hydraulic station pipeline. A pressure mold is fixedly installed on the telescopic end of the hydraulic push rod. The shape and size of the pressure mold are adapted to the upper opening of the forming frame.

[0007] Furthermore, a control box is fixedly installed on top of the base. The control box contains a microprocessor, and the feeding mechanism, adding mechanism, and forming mechanism are all electrically connected to the control box.

[0008] As a further description of the above technical solution: by setting up a control box, intelligent control and precise coordination of the entire cold pressing process can be achieved.

[0009] Furthermore, a guide slide rod is fixedly installed on the top of the mold, and the guide slide rod is slidably installed inside the reserved light hole on the surface of the top frame.

[0010] As a further description of the above technical solution: by setting a guide slide bar, a stable guide can be provided during the up and down movement of the mold, effectively preventing the mold from shifting or tilting due to uneven force, ensuring precise docking between the mold and the forming frame, and improving the dimensional accuracy and appearance consistency of the formed material.

[0011] Furthermore, the forming frame is a rectangular frame structure that runs vertically through the body. The bottom side of the forming frame overlaps the top of the support platform. A support slide rod is horizontally arranged between the support platform and the base. The forming frame is slidably connected to the surface of the support slide rod. A hydraulic telescopic rod is embedded in the top left side of the support platform. The telescopic end of the hydraulic telescopic rod is fixed to the left end face of the forming frame. The hydraulic telescopic rod is connected to the external hydraulic station pipeline. A pressure sensor is fixedly installed on the upper left side of the support platform. The position of the forming frame corresponds to that of the pressure sensor. The sensing end of the pressure sensor is in contact with the left side of the forming frame to monitor the position of the forming frame under the push of the hydraulic telescopic rod. The extension of the hydraulic telescopic rod pushes the forming frame to slide to the right along the support slide rod and away from the end face of the support platform. A rubber pad is provided on the surface of the base corresponding to the lower opening of the forming frame.

[0012] As a further description of the above technical solution: the forming frame overlaps the top of the support platform and slides with the support slide rod. After the material is cold-pressed in the forming frame, the hydraulic telescopic rod extends and pushes the forming frame to slide to the right along the support slide rod, so that its lower opening gradually moves away from the support platform and corresponds to the rubber pad on the base surface. At this time, the bottom of the forming frame loses support, and the formed material falls from the lower opening of the forming frame into the rubber pad under its own gravity, completing the automatic demolding. There is no need for manual material handling, which not only reduces the labor intensity of operators, but also avoids the safety hazards in the process of manual material handling. At the same time, the pressure sensor can monitor the position status of the forming frame to ensure that the position of the forming frame corresponds precisely with the mold, ensuring the accurate execution of the forming process.

[0013] Furthermore, the top of the storage tank is provided with a liquid injection port, the surface of which is provided with a sealing cap, and the side of the storage tank is fitted with a liquid level observation window, the surface of which is marked with capacity scale lines to facilitate real-time monitoring of the remaining amount of adhesive.

[0014] As a further description of the above technical solution: by setting up a liquid level observation window and a liquid injection port, the operator can intuitively view the liquid level of the adhesive in the storage tank. When the liquid level is lower than the scale line, the sealing cover can be opened and the adhesive can be replenished in time through the liquid injection port to avoid affecting the dust forming effect due to insufficient adhesive. At the same time, the sealing cover can effectively prevent the adhesive from being contaminated or volatilized by the outside world during storage, ensuring the stability of the adhesive performance.

[0015] Furthermore, vibrators are fixedly installed on the outer wall of the feed hopper and the outer wall of the forming frame.

[0016] As a further description of the above technical solution: by installing vibrators on the feed hopper and the outer wall of the forming frame, the vibrators can cause the dust in the feed hopper to fall quickly during feeding, avoiding the accumulation and blockage of materials on the inner wall of the feed hopper. After forming, the vibrators can cause slight vibration and separation between the inner wall of the forming frame and the materials, preventing the materials from sticking to the inner wall of the forming frame, and facilitating subsequent demolding and material removal operations.

[0017] The technical effects and advantages of this utility model are as follows: 1. This cold-pressing molding device for treating industrial blast furnace dust features a geared motor driving a spiral auger to rotate within the feed pipe during the feeding stage. This forcefully conveys the dust material, effectively preventing pipe blockage, and achieves uniform feeding through spiral pushing. Subsequently, a hydraulic push rod drives the die to perform cold-pressing molding of the mixture within the molding frame. During material conveying, a conveying pump quantitatively delivers the adhesive from the storage tank to the top of the feed pipe cavity via the conveying pipe and connecting pipe. This allows the adhesive to be fully mixed with the dust material under the stirring action of the spiral auger, enhancing the structural strength of the molded material and solving the problem of material loosening caused by traditional direct extrusion.

[0018] 2. This cold-pressing forming device for treating industrial blast furnace dust, through the installation of a control box, enables intelligent control and precise coordination of the entire cold-pressing forming process; by setting up guide slides, it can provide stable guidance during the up-and-down movement of the die, effectively preventing the die from shifting or tilting due to uneven force, ensuring precise docking between the die and the forming frame, and improving the dimensional accuracy and appearance consistency of the formed material; by installing vibrators on the feeding hopper and the outer wall of the forming frame, the vibrators can promote the rapid falling of dust in the feeding hopper during feeding, avoiding material accumulation and blockage on the inner wall of the feeding hopper; after forming, the vibrators can cause slight vibration and separation between the inner wall of the forming frame and the material, preventing the material from sticking to the inner wall of the forming frame, facilitating subsequent demolding and material removal operations.

[0019] 3. This cold-pressing molding device for treating industrial blast furnace dust consists of a molding frame that overlaps on top of a support platform and is slidably connected to a support slide rod. After the material is cold-pressed in the molding frame, the hydraulic telescopic rod extends and pushes the molding frame to slide to the right along the support slide rod, causing its lower opening to gradually move away from the support platform and align with the rubber pad on the base surface. At this point, the bottom of the molding frame loses support, and the molded material falls from the lower opening of the molding frame onto the rubber pad under its own gravity, completing automatic demolding without the need for manual material handling. This not only reduces the labor intensity of operators but also avoids safety hazards during manual material handling. At the same time, the pressure sensor can monitor the position of the molding frame to ensure that the position of the molding frame corresponds precisely to the mold, ensuring the accurate execution of the molding process.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The cold pressing forming device for industrial blast furnace dust treatment involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1 to 4 This utility model provides a cold pressing forming device for industrial blast furnace dust treatment, including a base 1. The upper surface of the base 1 is respectively provided with a feeding mechanism 2, an adding mechanism 3 and a forming mechanism 4. A control box 5 is fixedly installed on the top of the base 1. The control box 5 has a built-in microprocessor. The feeding mechanism 2, the adding mechanism 3 and the forming mechanism 4 are all electrically connected to the control box 5.

[0024] During installation, the control box 5 is connected to the external mains power supply, and the control box 5 is used to realize intelligent control and precise coordination of the entire cold pressing process.

[0025] The feeding mechanism 2 includes a feeding pipe 201 fixedly installed above the base 1. A feeding hopper 202 is fixedly connected to the upper left of the feeding pipe 201. A spiral auger blade 203 is rotatably connected to the inner wall of the feeding pipe 201. A reduction motor 204 for driving the spiral auger blade 203 to rotate is fixedly installed at the left end of the feeding pipe 201. A discharge pipe 205 is embedded at the right end of the feeding pipe 201.

[0026] During the feeding stage, the geared motor 204 drives the spiral auger blade 203 to rotate inside the feed pipe 201, which can both force the conveying of the dust raw material and effectively avoid pipe blockage, and achieve uniform feeding through spiral pushing.

[0027] The adding mechanism 3 includes a storage tank 301 fixedly installed on the surface of the base 1. The storage tank 301 contains adhesive. A delivery pump 302 is provided on the front bottom side of the storage tank 301. The inlet end of the delivery pump 302 extends into the interior of the storage tank 301. The outlet end of the delivery pump 302 is fixedly connected to a delivery pipe 303. Several connecting pipes 304 are equidistantly embedded on the surface of the delivery pipe 303. The other end of the connecting pipe 304 extends to the top of the inner cavity of the feed pipe 201.

[0028] By setting up the adding mechanism 3, during the material conveying process, the conveying pump 302 quantitatively conveys the adhesive in the storage tank 301 to the top of the inner cavity of the feed pipe 201 through the conveying pipe 303 and the connecting pipe 304, so that the adhesive is fully mixed with the dust raw material under the stirring action of the spiral auger blade 203, which enhances the structural strength of the material after molding and solves the problem of material looseness caused by traditional direct extrusion.

[0029] The top of the liquid storage tank 301 is provided with a liquid injection port, and the surface of the liquid injection port is provided with a sealing cap 305. The side of the liquid storage tank 301 is fitted with a liquid level observation window 306, and the surface of the liquid level observation window 306 is marked with a capacity scale line, which facilitates real-time monitoring of the remaining amount of adhesive, so as to replenish the adhesive in time through the liquid injection port and ensure the continuous and stable operation of the adding mechanism 3.

[0030] The molding mechanism 4 includes a support platform 401 fixedly installed on the surface of the base 1. A molding frame 402 is provided on the top of the support platform 401. The upper opening of the molding frame 402 corresponds to the position of the discharge pipe 205 of the feed pipe 201. A top frame 403 is fixedly installed on the top of the support platform 401. A hydraulic push rod 404 is embedded on the surface of the top frame 403. The hydraulic push rod 404 is connected to the external hydraulic station pipeline. A pressure mold 405 is fixedly installed on the telescopic end of the hydraulic push rod 404. The shape and size of the pressure mold 405 are adapted to the upper opening of the molding frame 402.

[0031] A guide slide rod 406 is fixedly installed on the top of the mold 405, and the guide slide rod 406 is slidably installed inside the reserved light hole on the surface of the top frame 403.

[0032] Under the conveying action of the feeding mechanism 2, the mixed material enters the forming frame 402 through the discharge pipe 205. When the material filling amount reaches the preset value, the reduction motor 204 stops running, and the feeding stops. At this time, the hydraulic push rod 404 extends downward under the drive of the external hydraulic station, driving the die 405 to move smoothly down along the trajectory of the guide slide rod 406 and accurately embed into the upper opening of the forming frame 402. The die 405 applies a preset pressure to the mixed material in the forming frame 402 to perform cold pressing molding. During the pressing process, the guide slide 406 ensures that the mold 405 will not shift or tilt due to uneven force, ensuring the precise docking of the mold 405 and the forming frame 402, thereby ensuring the dimensional accuracy and appearance consistency of the formed material. After the cold pressing process continues for a preset time, the hydraulic push rod 404 drives the mold 405 to reset upward.

[0033] The forming frame 402 is a rectangular frame structure that runs vertically through the body. The bottom side of the forming frame 402 overlaps the top of the support platform 401. A support slide rod 407 is horizontally arranged between the support platform 401 and the base 1. The forming frame 402 is slidably connected to the surface of the support slide rod 407. A hydraulic telescopic rod 408 is embedded and installed on the top left side of the support platform 401. The telescopic end of the hydraulic telescopic rod 408 is fixed to the left end face of the forming frame 402. The hydraulic telescopic rod 408 is connected to the external hydraulic station pipeline. A pressure sensor 410 is fixedly installed in the upper left corner. The position of the molding frame 402 corresponds to that of the pressure sensor 410. The sensing end of the pressure sensor 410 is in contact with the left side of the molding frame 402. It is used to monitor the position of the molding frame 402 under the push of the hydraulic telescopic rod 408. The hydraulic telescopic rod 408 extends and pushes the molding frame 402 to slide to the right along the support slide rod 407 and away from the end face of the support platform 401. A rubber pad 409 is provided on the surface of the base 1 corresponding to the lower opening of the molding frame 402.

[0034] The molding frame 402 is attached to the top of the support platform 401 and is slidably connected to the support slide rod 407. After the material is cold-pressed in the molding frame 402, the control box 5 controls the hydraulic telescopic rod 408 to extend, pushing the molding frame 402 to slide to the right along the support slide rod 407. During the sliding process, the sensing end of the pressure sensor 410 is disengaged from the left side of the molding frame 402, and its pressure signal changes and is fed back to the control box 5. At this time, the lower opening of the molding frame 402 is completely disengaged from the support of the support platform 401 and corresponds vertically to the rubber pad 409 on the surface of the base 1. Since the molding frame 402 is a vertically continuous structure, the molded material falls from the lower opening of the molding frame 402 under its own gravity and falls steadily onto the rubber pad 409, completing the automatic demolding.

[0035] The rubber pad 409 can cushion and protect the falling molded material, preventing it from breaking due to impact.

[0036] After the demolding action is completed, the control box 5 controls the hydraulic telescopic rod 408 to retract, driving the molding frame 402 to slide to the left along the support slide rod 407 to reset until the left side of the molding frame 402 contacts the sensing end of the pressure sensor 410 again and applies a certain pressure. The pressure sensor 410 feeds back the pressure signal to the control box 5. The control box 5 confirms that the molding frame 402 has been reset to the molding position, and the next round of feeding and molding operations can be carried out.

[0037] This automatic demolding design eliminates the need for manual removal of materials from the mold, significantly reducing the labor intensity of operators and completely eliminating potential safety hazards caused by mold temperature or sharp edges. It also greatly improves material handling efficiency and effectively ensures the continuity of the overall processing flow.

[0038] Vibrators 6 are fixedly installed on the outer wall of the feed hopper 202 and the outer wall of the forming frame 402.

[0039] During the feeding process, the vibrator 6 on the outer wall of the feed hopper 202 is activated. The high-frequency vibration generated by the vibrator 6 is transmitted to the feed hopper 202, causing the dust material in the feed hopper 202 to slide down quickly and smoothly into the feed pipe 201. This effectively avoids the accumulation and blockage of the dust material on the inner wall of the feed hopper 202 due to its small particle size and easy moisture absorption, ensuring the continuity and stability of the feeding process.

[0040] During the process of material filling into the molding frame 402 and demolding after cold pressing, the vibrator 6 on the outer wall of the molding frame 402 is activated. The high-frequency vibration can make the material particles in the molding frame 402 more compact, improving the density and structural strength of the molded material. At the same time, during demolding, the vibration can also promote the rapid separation of the molded material from the inner wall of the molding frame 402, further preventing the material from sticking to the inner wall of the molding frame 402, ensuring a smooth and efficient demolding process.

[0041] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
