Description

Technical Field

[0001] The invention belongs to the technical field of metallurgical powder conveying, and in particular relates to an electrically automated metallurgical powder conveying device and a conveying method. Background Art

[0002] Powder metallurgy materials have unique chemical compositions and physical and mechanical properties that cannot be obtained by traditional melting and casting processes, such as controllable porosity, uniform material structure, no macro-segregation (after the alloy solidifies, there is no uneven chemical composition in different parts of its cross section caused by the macroscopic flow of liquid alloy), and can be formed in one go.

[0003] Corresponding conveying devices are required in the process of metallurgical powder processing. The patent document with announcement number CN213257094U discloses a metallurgical powder feeding device. The left side of the device is a metallurgical powder conveying device, including a conveying box with a spiral conveying roller. A feed hopper is provided on one side of the conveying box, and a feed pipe is provided on the other side. The metallurgical powder is conveyed from the feed hopper to the feed pipe through the spiral conveying roller and enters the feeding port of the next process. Existing electrical automation metallurgical powder conveying devices are basically of this structure. During use, the metallurgical powder conveying device manually injects the metallurgical powder from the feed hopper into the conveying barrel. During the manual injection process, a large amount of dust will be generated at the moment of falling, and the generated dust will spread around the equipment, which will not only affect the health of the staff, but also lead to the low environmental protection of the device. In addition, in the existing metallurgical powder conveying device, some powder will adhere to the inner wall of the conveying barrel during the spiral conveying of the metallurgical powder. After the conveying, the staff needs to manually knock on the outer wall of the conveying barrel to shake off the attached metallurgical powder by vibration, so as to achieve the cleaning of the metallurgical powder. This is not only time-consuming and labor-intensive, but also leads to the low functionality of the device. Summary of the invention

[0004] In order to solve the above-mentioned drawbacks of the prior art, the present invention discloses an electrically automated metallurgical powder conveying device and conveying method, which adopts the following technical means:

[0005] An electrically automated metallurgical powder conveying device comprises an adjustable bracket, a dust collecting device and a conveying cylinder arranged on the adjustable bracket, wherein an inverted cone-shaped feed hopper is arranged above one side of the conveying cylinder, and a discharge pipe is arranged below the other side of the conveying cylinder.

[0006] The dust collecting device comprises a guide ring, a dust collecting pipe and a dust collecting machine, wherein the dust collecting machine is connected to the guide ring through the dust collecting pipe; the guide ring is a hollow annular structure arranged around the feed hopper, and the guide ring is embedded in the inner wall of the feed hopper. Preferably, the guide ring is embedded in the upper part of the feed hopper, and the part of the guide ring exposed outside the inner wall of the feed hopper is provided with a plurality of adsorption holes, and a filter plate is also provided in the feed hopper below the guide ring;

[0007] A rotating shaft is provided in the conveying cylinder, a spiral blade is provided on the rotating shaft, a sleeve is provided at one end of the rotating shaft, a connecting rod is provided on the sleeve, a scraper is provided on the connecting rod, the scraper is arranged parallel to the rotating shaft and contacts the inner wall of the conveying cylinder, a conveying motor is installed on the conveying cylinder, and the output shaft of the conveying motor is fixedly connected to the rotating shaft.

[0008] By adopting the above technical solution, the dust generated during the manual injection process can be adsorbed and collected by the vacuum cleaner through the adsorption holes, the guide pipe and the dust suction pipe in sequence, so as to prevent the dust from spreading around the equipment; during the metallurgical powder conveying process, the rotating shaft can also drive the scraper on the connecting rod to rotate along the inner wall of the conveying cylinder through the shaft sleeve, thereby automatically cleaning the metallurgical powder attached to the inner wall of the conveying cylinder.

[0009] Furthermore, the electrically automated metallurgical powder conveying device of the present invention also includes a material collecting device, which is arranged on the dust suction pipe. The material collecting device includes an adsorption cylinder and a return hopper. An arc-shaped electromagnet is provided on the upper inner side of the adsorption cylinder, and the curvature of the electromagnet is consistent with the inner wall of the adsorption cylinder; the return hopper is an inverted cone structure, which is arranged below the adsorption cylinder, and a manual valve is provided at the bottom of the return hopper.

[0010] During the filling process of metallurgical powder, the dust generated is mainly dust and dust of the metallurgical powder that is raised. In addition, the present invention embeds the guide ring in the inner wall of the feed hopper, so that the dust can be effectively collected without affecting the feeding. However, it is inevitable that a part of the metallurgical powder that does not fall into the conveying cylinder in time will also be adsorbed into the dust collector through the guide ring. The dust finally collected in the dust collector is mainly metallurgical powder and dust. If it is directly discarded, it will cause waste of metallurgical powder. If the dust collected by the dust collector is processed again to recover the metallurgical powder, it will be time-consuming and labor-intensive. The present invention arranges a gathering device. When the dust carrying the metallurgical powder passes through the gathering device, the metallurgical powder can be adsorbed by the electromagnet above the gathering device, and the dust in the dust is adsorbed and collected by the dust collector after passing through the gathering device. By setting the return hopper to an inverted cone, when the filling is completed, the manual valve below the return hopper is opened to cut off the power to the electromagnet, and the metallurgical powder can be discharged from the return hopper by its own gravity.

[0011] Furthermore, the adsorption cylinder has the same inner diameter as the dust suction pipe, the dust suction pipe includes a tube body I and a tube body II, and both ends of the adsorption cylinder are threadedly connected to the tube body I and the tube body II respectively.

[0012] Furthermore, the connecting rod includes a fixed part and a movable part, the fixed part is fixedly connected to the sleeve, the lower end of the movable part extends into the fixed part and is connected to the bottom of the fixed part through a buffer spring, and the scraper is connected to the movable part.

[0013] The buffer spring can provide buffer protection when the scraper encounters hard agglomerated materials during the cleaning process, thereby preventing the scraper from being damaged due to hard scraping and ensuring the cleaning effect.

[0014] Furthermore, the vacuum cleaner is fixed on the conveying cylinder, and two groups of filter screens with different specifications are arranged in the vacuum cleaner, and the filter screens are slidably arranged in the vacuum cleaner.

[0015] Further, the adjustable bracket includes a moving frame, a bearing plate, an electric push rod and an adjustment seat, the moving frame is a U-shaped structure, the bearing plate is arranged at the middle of the inner side of the moving frame, the electric push rod is arranged on the bearing plate, and the adjustment seat is a U-shaped structure, which is arranged on the movable end of the electric push rod;

[0016] The conveying cylinder is rotatably mounted in the adjusting seat, an adjusting motor is mounted on the side wall of the adjusting seat, and an output shaft of the adjusting motor is fixedly connected to the conveying cylinder.

[0017] Furthermore, supports are welded at the four corners of the movable frame, a screw sleeve is fixed inside the support, an adjusting screw is screwed inside the screw sleeve, and a support plate is installed at the bottom end of the adjusting screw.

[0018] Furthermore, universal wheels are installed at the four corners of the bottom end of the movable frame through bolts.

[0019] The present invention also discloses a metallurgical powder conveying method using any of the above-mentioned electrical automation metallurgical powder conveying devices, comprising the following steps:

[0020] Move the electrical automation metallurgical powder conveying device to the working position through the adjustable bracket so that the discharge pipe is located directly above the feed inlet of the processing equipment;

[0021] The conveying motor and the vacuum cleaner are started, and the metallurgical powder is injected into the feed hopper. The filter plate filters the impurities in the metallurgical powder. The filtered metallurgical powder falls into the conveying cylinder. The conveying motor drives the spiral blade to rotate through the rotating shaft, thereby spirally conveying the metallurgical powder and discharging it into the processing equipment through the discharge pipe;

[0022] During the injection process, the dust collector absorbs and collects the dust generated during the injection process through the dust collection pipe and the guide ring;

[0023] During the metallurgical powder conveying process, the rotating shaft drives the scraper on the connecting rod to rotate along the inner wall of the conveying cylinder through the shaft sleeve, thereby automatically cleaning the metallurgical powder attached to the inner wall of the conveying cylinder.

[0024] Furthermore, the metallurgical powder conveying method further comprises the following steps:

[0025] When the vacuum cleaner is turned on, the electromagnet is energized. When the dust flows through the adsorption cylinder on the dust suction pipe, the electromagnet can adsorb the metal powder entrained in the dust to separate it from the dust. After the filling is completed, the manual valve at the bottom of the return hopper is opened and the electromagnet is powered off. At this time, the metal powder adsorbed on the electromagnet is discharged from the return hopper for recovery under the action of gravity.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The present invention provides a vacuum cleaner, a vacuum tube, a guide ring and an adsorption hole. During the manual injection process, the vacuum cleaner absorbs and collects the dust generated during the injection process through the vacuum tube, the guide ring and the adsorption hole to prevent the dust from spreading around the equipment. By providing a shaft sleeve, a connecting rod and a scraper, during the conveying process, the rotating shaft also drives the scraper on the connecting rod to rotate along the inner wall of the conveying cylinder through the shaft sleeve, thereby automatically cleaning the metallurgical powder attached to the inner wall of the conveying cylinder. On the one hand, the conveying effect of the metallurgical powder is guaranteed, and on the other hand, manual cleaning is unnecessary, which saves time and effort and improves the functionality of the device.

[0028] 2. The present invention arranges a collecting device consisting of an adsorption cylinder, an electromagnet, a return hopper and a manual valve on the dust suction pipe. While removing dust, the electromagnet can use the magnetic properties of metal powder to adsorb metal powder mixed in the dust to separate it from the dust. After the filling is completed, the return hopper is opened through the manual valve, and then the electromagnet is powered off. At this time, the adsorbed metal powder relies on its own gravity to be discharged through the return hopper for recovery. On the one hand, the dust removal effect of the device is guaranteed, and on the other hand, the waste of metal powder is avoided, and the use effect is good.

[0029] 3. The present invention provides a buffer spring, which can provide buffer protection when the scraper encounters hard agglomerated materials during the cleaning process, thereby preventing the scraper from being damaged due to hard scraping and ensuring the cleaning effect.

[0043] A rotating shaft 9 is rotatably installed in the conveying cylinder 1, and a spiral blade 10 is fixed on the rotating shaft 9 by screws. A conveying motor 14 is installed at the bottom of the conveying cylinder 1, and the output shaft of the conveying motor 14 is fixedly connected to the rotating shaft 9.

A scraper 13 is arranged on the connecting rod 12, and the scraper 13 is arranged parallel to the rotating shaft 9 and the scraper 13 contacts the inner wall of the conveying cylinder 1. The rotating shaft 9 drives the scraper 13 on the connecting rod 12 to rotate along the inner wall of the conveying cylinder 1 through the sleeve 11, thereby automatically cleaning the metallurgical powder attached to the inner wall of the conveying cylinder 1.

[0044] In a preferred solution, the connecting rod 12 is an L-shaped connecting rod with a telescopic structure, including a fixed portion 19 and a movable portion 20, wherein the fixed portion 19 is welded to the shaft sleeve 11, and the lower end of the movable portion 20 extends into the fixed portion 19 and is connected to the bottom of the fixed portion 19 through a buffer spring 21, and the scraper 13 is connected to the movable portion 20 through a screw. The buffer spring 21 can provide buffer protection for the scraper 13 when it encounters hard agglomerated materials during the cleaning process, thereby preventing the scraper 13 from being damaged due to hard scraping and ensuring its cleaning effect.

[0045] The adjustable bracket includes a mobile frame 23 of a U-shaped structure, and universal wheels 32 are installed at the four corners of the bottom of the mobile frame 23 by bolts, and the universal wheels 32 facilitate the movement of the device.

The adjusting screw 30 is rotated to drive the support plate 31 to move downward under the action of the screw sleeve 29. The device is supported by the support plate 31 to ensure the stability of the device when working.

[0047] The method of using the electrical automation metallurgical powder conveying device implemented in this embodiment is as follows:

[0048] The metallurgical powder conveying device is moved to the working position by the universal wheel 32, and then the adjusting screw 30 is rotated to drive the support plate 31 to move downward under the action of the screw sleeve 29, and the metallurgical powder conveying device is supported by the support plate 31 to ensure the stability of the metallurgical powder conveying device during operation, and then the external power supply is turned on to control the electric push rod 25 to adjust the height of the conveying cylinder 1, and then the adjusting motor 27 is controlled to drive the conveying cylinder 1 to rotate to adjust its inclination angle, and finally the discharge pipe 3 is located directly above the feed port of the metallurgical powder processing equipment;

At this time, the conveying motor 14 drives the spiral blade 10 to rotate through the rotating shaft 9, and then the metallurgical powder is spirally conveyed and discharged into the processing equipment through the discharge pipe 3, so as to realize the conveying of metallurgical powder;

[0050] During the conveying process, the rotating shaft 9 also drives the scraper 13 on the connecting rod 12 to rotate along the inner wall of the conveying cylinder 1 through the shaft sleeve 11, thereby automatically cleaning the metallurgical powder attached to the inner wall of the conveying cylinder 1.

[0052] Example 2

[0053] like Figures 6-7 As shown, this embodiment discloses an electrically automated metallurgical powder conveying device, and the similarities with the embodiment 1 are not repeated here. The difference between this embodiment and the embodiment 1 is that:

[0055] During dust removal, the electromagnet 17 can utilize the magnetic properties of metal powder to adsorb metal powder mixed in the dust and separate it from the dust. When the filling is completed, the return hopper 16 is opened through the manual valve 18, and then the electromagnet 17 is powered off. At this time, the adsorbed metal powder relies on its own gravity to be discharged through the return hopper 16 for recycling, avoiding waste of metal powder.
