Description

Technical Field

[0001] This invention relates to the field of powder storage tank technology, specifically to a powder transfer tanker and its operating method. Background Technology

[0002] Composite powder refers to the process of using a mixture of metal powder and non-metal powder as raw materials, which is then formed and sintered, and followed by necessary post-processing to obtain metal materials, composite materials and various types of products. Various metal and non-metal materials are crushed into powder and need to be stored, transported, mixed and processed in the next step.

[0003] Currently, the powder workshop uses ordinary PV rubber buckets to fill the powder at the outlet of the spray drying tower. After filling, the powder is transferred to the next process by pallet forklift for powder distribution and compaction. However, it is very inconvenient to transfer the powder after filling the ordinary buckets, and it will make it impossible to unload the powder in the next process. Summary of the Invention

[0004] The purpose of this invention is to provide a powder transfer tanker and its working method, which can facilitate the transfer of powder and the unloading operation of the next process, making it convenient and fast, improving work efficiency, and solving the technical problem that it is very inconvenient to transfer the powder after it is loaded into the tank, and that it will lead to the inability to unload the powder in the next process.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A powder transfer tanker includes a tank support frame, with casters fixedly installed at the lower end of the support frame. A storage tank for storing powder is fixedly installed on the upper part of the support frame. A push rod for pushing and pulling the tanker is fixedly installed on the side wall of the storage tank. A tank cover is provided at the upper opening of the storage tank. A titanium breather valve for adjusting the air pressure inside the storage tank is fixedly installed on the tank cover. A feed inlet for receiving powder is provided on the tank cover, and a feed cover plate is provided at the feed inlet. A discharge valve for controlling the discharge of powder is provided at the lower outlet of the storage tank. An auxiliary discharge mechanism to prevent powder from sticking to the wall is installed on the storage tank.

[0007] Preferably, the auxiliary discharge mechanism includes multiple mounting supports fixedly installed on the side wall of the storage tank, and a vibrator is fixedly installed on the mounting supports.

[0008] Preferably, the auxiliary discharge mechanism includes a stirring motor fixedly installed on the tank cover, the output end of the stirring motor is fixedly connected to a stirring shaft, and the stirring shaft extends into the inside of the storage tank and is fixedly installed with several stirring support rods.

[0009] Preferably, a plurality of upper connecting rods are fixedly installed on the upper part of the stirring shaft, and a tank wall scraper is fixedly connected to the upper connecting rod. The outer side of the tank wall scraper slides against the inner wall of the storage tank. A lower connecting rod is fixedly connected to the lower part of the tank wall scraper. The lower connecting rod is fixedly connected to the lower part of the stirring shaft.

[0010] Preferably, the storage tank includes an outer tank and an inner tank, with an isolation cavity formed between the outer tank and the inner tank, and the auxiliary discharge mechanism is installed at the outer tank and the isolation cavity.

[0011] Preferably, the auxiliary discharge mechanism includes a vibrating slide rod that is slidably connected to the lower part of the side wall of the outer tank. One end of the vibrating slide rod located in the isolation cavity is fixedly connected to an inner wall vibrating plate, and the other end of the vibrating slide rod is fixedly connected to a counterweight. A vibrating spring is sleeved on the outer periphery of the vibrating slide rod, and the vibrating spring is connected between the counterweight and the outer wall of the outer tank.

[0012] Preferably, the auxiliary discharge mechanism includes a transmission mechanism that is horizontally slidably connected through the lower part of the side wall of the outer tank and a fixed base plate that is fixedly installed on the tank support. A bearing sleeve is fixedly provided on the upper part of the fixed base plate. A connecting sleeve is rotatably installed on the outside of the bearing sleeve through a connecting bearing. A rotating sleeve is fixedly connected to the outside of the drive motor through a connecting block. Corrugated internal teeth for driving the transmission mechanism are provided on the inner side of the rotating sleeve.

[0013] Preferably, a drive motor is fixedly installed on the lower part of the fixed base plate, a drive gear is fixedly installed on the output shaft of the drive motor, and an outer gear tooth that cooperates with the drive gear is fixedly provided on the outer periphery of the rotating sleeve.

[0014] Preferably, the transmission mechanism includes a transmission link that slides horizontally through the lower part of the side wall of the outer tank. A vibration plate is fixedly connected to one side of the transmission link located in the isolation cavity. A pulley support is fixedly connected to the other end of the transmission link. A transmission pulley that meshes with the corrugated internal teeth is rotatably mounted on the pulley support. A return spring is sleeved on the outer periphery of the transmission link. The return spring is connected between the pulley support and the outer wall of the outer tank.

[0015] Preferably, a method for operating a powder transfer tanker involves moving the tanker by pushing and pulling a push rod, pushing the tanker to the spray drying tower, opening the feed cover to align the tanker's feed inlet with the spray drying tower's discharge outlet, loading the powder into the storage tank, and then closing the feed cover. Subsequently, the push rod is moved to the next process step, and the discharge valve is opened to discharge the powder stored in the storage tank. During the discharge process, a titanium breather valve is used to maintain atmospheric pressure inside the storage tank, while an auxiliary discharge mechanism is activated to assist in powder discharge, ensuring that the powder is discharged and avoids accumulation on the walls.

[0016] The beneficial effects of this invention are:

[0017] (1) By adding a titanium breather valve, the normal pressure inside the storage tank is ensured, thus ensuring the quality of the powder. A discharge valve is added to the discharge port to enable pneumatic switching. A vibrator is added to accelerate the discharge and prevent the powder from sticking to the wall.

[0018] (2) The powder is stored by setting a double-layer storage tank. The double-layer structure facilitates the installation of a unique auxiliary discharge mechanism, improves the rapid discharge of powder, and the isolation cavity in the middle of the double-layer storage tank improves the stability of powder storage. In other embodiments, the isolation cavity can be filled with a heat insulation layer or other isolation materials to effectively improve the heat preservation performance of powder storage.

[0019] (3) By setting the combination of vibration spring and counterweight, the counterweight drives the vibration spring to extend and retract during the movement of the tank truck, thereby driving the inner wall vibrating plate to continuously hit the inner tank, realizing the vibration of the powder, effectively preventing the powder from condensing and sticking to the wall in the storage tank, and ensuring the discharge efficiency and complete discharge of the powder.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] Please see Figures 1-2 As shown, the present invention is a powder transfer tanker, including a tank support 10, with casters 20 fixedly installed at the lower end of the tank support 10, a storage tank 30 for storing powder fixedly installed at the upper part of the tank support 10, a tank push rod 40 for pushing and pulling the tanker fixedly installed on the side wall of the storage tank 30, a tank cover 50 provided at the upper opening of the storage tank 30, a titanium breather valve 60 for adjusting the air pressure inside the storage tank 30 fixedly installed on the tank cover 50, a feed inlet for receiving powder provided on the tank cover 50, and a feed cover plate 70 provided at the feed inlet; a discharge valve 80 for controlling the discharge of powder is provided at the lower outlet of the storage tank 30, and an auxiliary discharge mechanism for preventing powder from sticking to the wall is installed on the storage tank 30.

[0032] In this embodiment, the auxiliary discharge mechanism includes a plurality of mounting supports 91 fixedly installed on the side wall of the storage tank 30, and a vibrator 92 is fixedly installed on the mounting supports 91.

[0033] It should be noted that the vibrator 92 vibrates the side wall of the storage tank 30 to ensure that the powder can maintain the same vibration inside the storage tank 30, thereby effectively preventing the powder from agglomerating and sticking to the wall inside the storage tank 30, and ensuring the discharge efficiency and complete discharge of the powder. In addition, multiple vibrators 92 are distributed in a ring array on the outer wall of the storage tank 30 to ensure the comprehensive vibration of the powder.

[0034] Example 2

[0035] Unlike the above embodiment which uses a vibrator 92 to prevent powder from sticking to the wall, the vibrator 92 alone cannot break the adhesion of the powder in the center, which causes the adhered powder to block the outlet of the storage tank 30, resulting in the powder not being able to be discharged normally.

[0036] Please see Figure 3 As shown, the auxiliary discharge mechanism includes a stirring motor 11 fixedly installed on the tank cover 50. The output end of the stirring motor 11 is fixedly connected to a stirring shaft 12. The stirring shaft 12 extends into the storage tank 30 and is fixedly installed with several stirring support rods 13.

[0037] It should be noted that in this embodiment, the stirring motor 11 drives the stirring shaft 12 and the stirring support rod 13 to rotate. The stirring support rod 13 agitates the powder in the storage tank 30, thereby effectively preventing the powder from condensing in the storage tank 30 and ensuring that the powder can be discharged quickly. In other embodiments, the stirring support rod 13 can be a stirring plate, which is rotatably mounted on the stirring shaft 12. When the stirring plate rotates under the drive of the rotating stirring shaft 12, it rotates on its own under the action of the powder, thereby further improving the agitation effect on the powder.

[0038] In an optional embodiment, a plurality of upper connecting rods 15 are fixedly installed on the upper part of the stirring shaft 12, and a tank wall scraper 14 is fixedly connected to the upper connecting rod 15. The outer side of the tank wall scraper 14 slides against the inner wall of the storage tank 30, and a lower connecting rod 16 is fixedly connected to the lower part of the tank wall scraper 14. The lower connecting rod 16 is fixedly connected to the lower part of the stirring shaft 12.

[0039] It should be noted that, since the stirring shaft 12 and stirring support rod 13 are used to agitate the powder, the stirring support rod 13 cannot remove the powder adhering to the inner wall of the storage tank 30. Therefore, the tank wall scraper 14 is used to scrape the inner wall of the storage tank 30 to ensure that the powder does not adhere to the inner wall of the storage tank 30. In other embodiments, the upper connecting rod 15 and the lower connecting rod 16 are configured as telescopic rod structures, and the telescopic rods are connected by springs. The elasticity of the springs ensures that the tank wall scraper 14 is in close contact with the inner wall of the storage tank 30, thereby improving the scraping effect on the inner wall of the storage tank 30.

[0040] Example 3

[0041] Unlike the above embodiments that use a stirring shaft 12 and stirring rod 13 to agitate the powder, for some powders that are highly viscous or small in size, the stirring rod 13 alone cannot effectively control the feeding of the powder. In this case, vibration is still required to vibrate the storage tank. At the same time, the single-layer tank structure will be affected by the interference of the external environment, which will affect the storage of the powder inside and cause the powder to deteriorate during the transfer process.

[0042] Please see Figure 4 As shown, the storage tank 30 includes an outer tank 31 and an inner tank 32, with an isolation cavity 33 formed between the outer tank 31 and the inner tank 32. An auxiliary discharge mechanism is installed at the outer tank 31 and the isolation cavity 33.

[0043] It should be noted that by setting a double-layered storage tank 30 to store powder, the double-layered structure facilitates the installation of a unique auxiliary discharge mechanism, improves the rapid discharge of powder, and the isolation cavity 33 in the middle of the double-layered storage tank 30 improves the stability of powder storage. In other embodiments, the isolation cavity 33 can be filled with a heat insulation layer or other isolation materials to effectively improve the heat preservation performance of powder storage.

[0044] In an optional embodiment, please refer to Figure 4 As shown, the auxiliary discharge mechanism includes a vibrating slide rod 21 that is slidably connected to the lower part of the side wall of the outer tank 31. One end of the vibrating slide rod 21 located in the isolation cavity 33 is fixedly connected to an inner wall vibrating plate 22, and the other end of the vibrating slide rod 21 is fixedly connected to a counterweight block 23. A vibrating spring 24 is sleeved on the outer periphery of the vibrating slide rod 21, and the vibrating spring 24 is connected between the counterweight block 23 and the outer wall of the outer tank 31.

[0045] It should be noted that by setting the vibration spring 24 and the counterweight 23 together, the counterweight 23 drives the vibration spring 24 to extend and retract during the movement of the tanker, thereby causing the inner wall vibrating plate 22 to continuously impact the inner tank 32, thereby vibrating the powder and effectively preventing the powder from condensing and sticking to the wall in the storage tank 30, ensuring the discharge efficiency and complete discharge of the powder.

[0046] Furthermore, by combining the structure of this embodiment with the structure of Embodiment 2, stable powder feeding can be achieved.

[0047] Example 4

[0048] Based on the above embodiments, the powder inside the storage tank 30 is vibrated by a combination of a vibration spring 24 and a counterweight 23. This requires the counterweight 23 to be displaced due to the shaking of the tanker during movement. When the movement is relatively smooth, it is not possible to effectively trigger the vibration effect on the storage tank 30. Therefore, a triggering mechanism is needed to ensure that the storage tank 30 can be vibrated at any time.

[0049] Please see Figures 5-7 As shown, the auxiliary discharge mechanism includes a transmission mechanism 49 that is horizontally slidably connected to the lower part of the side wall of the outer tank 31 and a fixed base plate 41 that is fixedly installed on the tank support 10. A bearing sleeve 43 is fixedly installed on the upper part of the fixed base plate 41. A connecting sleeve 45 is rotatably installed on the outside of the bearing sleeve 43 through a connecting bearing 44. A rotating sleeve 47 is fixedly connected to the outside of the drive motor 42 through a connecting block 46. A corrugated internal tooth 471 for driving the transmission mechanism 49 is provided on the inner side of the rotating sleeve 47.

[0050] It should be noted that the rotation of the rotating sleeve 47 drives the corrugated inner teeth 471 to rotate. The concave and convex surfaces of the corrugated inner teeth 471 are connected to the drive transmission mechanism 49, thereby driving the drive transmission mechanism 49 to move horizontally back and forth, so as to impact the inner wall of the storage tank 30, thereby vibrating the powder to ensure stable discharge. In other embodiments, the bearing sleeve 43 can be selected to be sleeved on the outside of the rotating sleeve 47 to effectively prevent interference with the storage tank 30.

[0051] In an optional embodiment, a drive motor 42 is fixedly installed on the lower part of the fixed base plate 41, a drive gear 48 is fixedly installed on the output shaft of the drive motor 42, and an outer gear tooth 472 that cooperates with the drive gear 48 is fixedly provided on the outer periphery of the rotating sleeve 47.

[0052] It should be noted that by setting the drive motor 42 to drive the drive gear 48 to rotate, the gear meshing transmission drives the outer gear 472 and the rotating sleeve 47 to rotate, thereby driving the drive transmission mechanism 49. In other embodiments, the drive motor 42 can be a drive motor, the gear meshing mechanism can be a sprocket and chain mechanism, or even further, the drive motor 42 can be a linear drive mechanism of a cylinder or hydraulic cylinder, and the drive gear 48 can be a drive rack to drive the rotation of the rotating sleeve 47.

[0053] In an optional embodiment, the transmission mechanism 49 includes a transmission link 492 that is horizontally slidably connected through the lower part of the side wall of the outer tank 31. A vibration plate 491 is fixedly connected to one side of the transmission link 492 located in the isolation cavity 33. A pulley support 494 is fixedly connected to the other end of the transmission link 492. A transmission pulley 495 that cooperates with the corrugated internal gear 471 is rotatably mounted on the pulley support 494. A return spring 493 is sleeved on the outer periphery of the transmission link 492. The return spring 493 is connected between the pulley support 494 and the outer wall of the outer tank 31.

[0054] It should be noted that the transmission pulley 495, in conjunction with the corrugated internal gear 471, drives the transmission connecting rod 492 to move horizontally back and forth, thereby causing the vibrating plate 491 to continuously impact the inner tank 32, achieving vibration storage of powder. The reset spring 493 enables the transmission pulley 495 to be continuously reset. Furthermore, a corrugated groove is provided at the corrugated internal gear 471 to cooperate with the transmission pulley 495, thereby ensuring the stability of the connection between the transmission pulley 495 and the corrugated internal gear 471.

[0055] Example 5

[0056] This embodiment, based on the powder transfer tanker in the above embodiment, proposes a working method for the powder transfer tanker. The tanker is moved by pushing and pulling the tank push rod 40, pushing it to the spray drying tower. The feed cover 70 is opened to align the tanker's feed inlet with the spray drying tower's discharge outlet. After the powder is loaded into the storage tank 30, the feed cover 70 is closed. Then, the tank push rod 40 is pushed and pulled to move to the next process step, and the discharge valve 80 is opened to discharge the powder stored in the storage tank 30. During the discharge process, the titanium breather valve 60 maintains normal pressure inside the storage tank 30. Simultaneously, an auxiliary discharge mechanism is activated to assist in powder discharge, ensuring that powder is discharged and avoids accumulation and adhesion to the walls.

[0057] It should be noted that after the tanker truck is placed at the discharge port of the spray drying tower to receive the material, it is very convenient to transfer it to the next process via the caster 20. In addition, the addition of titanium breather valve 60 ensures normal pressure in the storage tank and ensures powder quality. The addition of discharge valve 80 at the discharge port can be pneumatically switched, and the addition of vibrator 92 accelerates the discharge and prevents powder from sticking to the wall.

[0058] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
