Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for conveying copper-gold powder, and in particular to a copper-gold powder feeding anti-blocking mechanism. Background Technology

[0002] Copper gold powder, also known as gold powder, is a metallic pigment made from copper-zinc alloy through special mechanical processing and surface chemical treatment. It has a scaly structure, can float in binders, exhibits a golden luster, and possesses pigment properties.

[0003] After processing, copper-gold powder needs to be transported to downstream equipment for further processing or storage. During the transport process, due to the fast feeding speed and large feeding volume, copper-gold powder is prone to arching, resulting in accumulation and blockage. This slows down the feeding process, reduces the feeding efficiency, and requires cleaning before the feeding can continue, thus affecting the working efficiency of copper-gold powder production. Utility Model Content

[0004] To address the technical problem of easy arching and blockage in the feeding of copper-gold powder, which leads to low feeding efficiency, this utility model provides a copper-gold powder feeding anti-blockage mechanism.

[0005] The technical solution of this utility model is achieved through the following scheme: a copper-gold powder feeding anti-blocking mechanism, including a box body, a first anti-arching device, a rebound filter plate and a second anti-arching device. The first anti-arching device is movably installed in the box body, and the anti-arching end of the first anti-arching device is directly facing the feed inlet of the box body. The rebound filter plate is obliquely arranged on the box body, and the lowest point of the rebound filter plate penetrates the box body and overlaps the distribution box.

[0006] The box is equipped with a first anti-arching device, a rebound filter plate, and a feeding guide layer in sequence along the vertical direction. The second anti-arching device is located inside the feeding guide layer, which is connected to the screw conveyor.

[0007] Through the above technical solutions, the first anti-arching device moves up and down inside the box to break up the arching, ensuring that the copper-gold powder can smoothly enter the box from the inlet and avoid obstruction of the discharge. The second anti-arching device continuously disturbs the copper-gold powder in the discharge guide layer, ensuring that the copper-gold powder can flow smoothly in the discharge guide layer, further improving the stability of the discharge and reducing the risk of blockage. The rebound filter plate screens the copper-gold powder, so that the copper-gold powder that may have been aggregated is redispersed into smaller particles or individual particles, reducing the possibility of arching caused by particle aggregation.

[0008] Preferably, the first arch-removing device includes a screw lifting device, an installation beam, a main arch-breaking head, and an arch-breaking ring. The installation beam is movably installed inside the box via the screw lifting device. The main arch-breaking head and the arch-breaking ring are fixedly installed on the installation beam, and the main arch-breaking head and the arch-breaking ring are directly opposite the feed inlet of the box.

[0009] Preferably, the screw lifting device is equipped with a bellows baffle protective cover, and the mounting beam is provided with a guide slope.

[0010] Through the above technical solutions, the screw lifting device provides flexible adjustment capabilities for the main arch-breaking head and the arch-breaking ring, and can divert material flow. The main arch-breaking head can concentrate force to impact and damage the local area of ​​the arch during arch breaking, breaking the structural balance of the arch, causing the arch to loosen and collapse. The arch-breaking ring disturbs and breaks the surrounding area of ​​the arch, preventing the arch from re-aggregating and forming a new arch after being broken by the main arch-breaking head, making the arch breaking more thorough and improving the smoothness of copper-gold powder feeding. The guide slope reduces the residue of powder on the installation beam, improving the utilization rate of powder. The bellows baffle can effectively block dust and particles from entering the screw lifting device, providing a relatively clean working environment for the screw and extending the service life of the screw lifting device.

[0011] Preferably, the second arch-removing device includes a supporting beam, a mounting shell, and a spiral roller. A drive motor is installed inside the mounting shell, and the drive end of the drive motor is connected to the spiral roller. Both the mounting shell and the spiral roller are mounted in the material feeding guide layer through the supporting beam.

[0012] Preferably, both the mounting shell and the supporting beam are provided with material distribution slopes.

[0013] Preferably, a vibration motor is fixedly installed at the bottom of the rebound filter plate near the material distribution box.

[0014] Preferably, the enclosure has an observation window.

[0015] Through the above technical solutions, the rotating spiral roller continuously stirs and propels the copper-gold powder, uniformly conveying it forward and preventing the powder from accumulating in the feeding guide layer. This effectively improves feeding efficiency and reduces production interruptions caused by blockages. The distribution slope prevents the powder from accumulating around the mounting shell and support beam, thus avoiding dead corners and effectively improving the utilization rate and uniformity of the powder feeding.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. This utility model uses a first anti-arching device that moves up and down inside the box to break up arches, ensuring that copper-gold powder can smoothly enter the box from the inlet and avoid obstruction of the discharge. The second anti-arching device continuously disturbs the copper-gold powder in the discharge guide layer, ensuring that the copper-gold powder can flow smoothly in the discharge guide layer, further improving the stability of the discharge and reducing the risk of blockage. The rebound filter plate screens the copper-gold powder, causing the copper-gold powder that may have been aggregated to redisperse into smaller particles or individual particles, reducing the possibility of arching caused by particle aggregation.

[0018] 2. The screw-lifting device provides flexible adjustment capabilities for the main arch-breaking head and the arch-breaking ring, and can divert material flow. The main arch-breaking head can concentrate force to impact and damage the local area of ​​the arch during arch breaking, breaking the structural balance of the arch, causing the arch to loosen and collapse. The arch-breaking ring disturbs and breaks the surrounding area of ​​the arch, preventing the arch from re-aggregating and forming a new arch after being broken by the main arch-breaking head, making the arch breaking more thorough and improving the smoothness of copper-gold powder feeding. The guide slope reduces the residue of powder on the installation beam, improving the utilization rate of powder. The bellows baffle can effectively block dust and particles from entering the screw-lifting device, providing a relatively clean working environment for the screw and extending the service life of the screw-lifting device.

[0019] 3. The rotating spiral roller continuously stirs and propels the copper-gold powder, conveying it evenly forward and preventing it from accumulating in the feeding guide layer. This effectively improves feeding efficiency and reduces production interruptions caused by blockages. The distribution slope prevents powder from accumulating around the mounting shell and support beam, thus improving powder utilization and feeding uniformity.

[0020] 4. The vibration motor prevents copper-gold powder from accumulating and clogging on the filter plate, keeping the pores on the filter plate clear and improving the filtration efficiency. At the same time, the vibration also helps to remove the copper-gold powder particles adhering to the filter plate, further ensuring the filtration effect of the filter plate.

[0028] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] A copper-gold powder feeding anti-clogging mechanism, such as Figures 1-6 As shown, the device includes a housing 1, a first anti-arching device 2, a rebound filter plate 3, and a second anti-arching device 5. The first anti-arching device 2 is movably installed inside the housing 1 and slides up and down on the housing 1. The anti-arching end of the first anti-arching device 2 is directly opposite the feed inlet of the housing 1, and a feed hopper is connected to the feed inlet of the housing 1. The first anti-arching device 2 can also be used as a slow-feed diversion device to divide the incoming powder into multiple groups for synchronous feeding, which can effectively prevent the powder from accumulating and falling, resulting in incomplete filtration by the rebound filter plate 3, and improve the uniformity and stability of the feeding.

[0031] like Figure 2 and Figure 3 As shown, the rebound filter plate 3 is obliquely mounted on the box body 1. The box body 1 is provided with a discharge port. The lowest point of the rebound filter plate 3 penetrates the box body 1 and overlaps the distribution box 9. The lowest point of the rebound filter plate 3 passes through the discharge port. The distribution box 9 abuts against the box body 1. Baffles are installed on both sides of the distribution box 9 to prevent material from flying.

[0032] Inside the housing 1, a first anti-arching device 2, a rebound filter plate 3, and a feeding guide layer 4 are installed sequentially along the vertical direction. A second anti-arching device 5 is located inside the feeding guide layer 4. The feeding guide layer 4 is connected to the screw conveyor 8. The feeding guide layer 4 is an inverted truncated pyramid with a certain inclination angle on its side wall, which can guide the powder filtered by the rebound filter plate 3 to smoothly converge downward and enter the screw conveyor 8, thereby improving the feeding efficiency.

[0033] The upper opening size of the feeding guide layer 4 is matched with the filter screen size of the rebound filter plate 3 to ensure that the filtered powder is fully received; the lower opening size should match the feed inlet of the screw conveyor 8 to ensure that the powder can smoothly enter the conveyor.

[0034] like Figure 1 As shown, the box 1 has an observation window, through which the operator can observe in real time the flow status of copper-gold powder during the feeding process, whether arching or blockage occurs, and the operation of the first arch removal device 2.

[0035] like Figure 4 As shown, the spring filter plate 3 consists of a filter plate and a spring column. The filter plate is connected to the housing 1 through the spring column. A vibration motor 6 is fixedly installed at the bottom of the spring filter plate 3 near the distribution box 9. The part of the spring filter plate 3 that overlaps on the distribution box 9 does not have a metal wire mesh, while the part inside the housing 1 has a metal wire mesh. Vibration can make the copper-gold powder passing through the spring filter plate 3 more dispersed. When the copper-gold powder vibrates on the filter plate, the collision and friction between particles are reduced, avoiding particle agglomeration. This allows the copper-gold powder to enter the feeding guide layer 4 in a more uniform and fine state, which is beneficial for the subsequent second anti-arching device 5 to break the arch and convey it. This improves the stability and reliability of the entire feeding system and also effectively accelerates the discharge of large particles and reduces their pause on the spring filter plate 3.

[0036] like Figure 2 and Figure 6As shown, the first arch-removing device 2 includes a screw lifting device 21, a mounting beam 22, a main arch-breaking head 23, and an arch-breaking ring 24. The mounting beam 22 is movably installed inside the housing 1 via the screw lifting device 21. The main arch-breaking head 23 and the arch-breaking ring 24 are fixedly installed on the mounting beam 22. The arch-breaking ring 24 is slightly lower than the main arch-breaking head 23 and surrounds the support column of the main arch-breaking head 23. The main arch-breaking head 23 and the arch-breaking ring 24 face the feed inlet of the housing 1. Corresponding mounting slots are opened on the two side walls of the housing 1 to install screws and limit rods, respectively. The mounting beam 22 is screwed between the screw moving seat and the limit rod moving seat. The screw is driven to rotate by a motor, making it move vertically. The reciprocating motion adjusts the positions of the main arch-breaking head 23 and the arch-breaking ring 24 to complete the arch-breaking action. The main arch-breaking head 23 is preferably a pyramidal head. Utilizing its sharp conical structure, it inserts into the powder frame arch during the up-and-down movement, destroying the structural stability of the frame arch through mechanical force, causing the frame arch to collapse and allowing the powder to fall smoothly. The arch-breaking ring 24 is an annular blade. After the conical head breaks the frame arch, the annular blade can further disturb and loosen the surrounding powder to prevent the frame arch from forming again. At the same time, the annular blade, together with the four sides of the pyramidal head, can also play a certain role in blocking and diverting the flow, ensuring that the powder can fall evenly onto the rebound filter plate 3.

[0037] The screw lifting device 21 is equipped with a bellows baffle 7 to prevent powder from entering the installation groove and splashing out, and to avoid the powder from causing wear and jamming on the screw, nut and other moving parts, thereby extending the service life of the screw lifting device 21 and ensuring its smooth and reliable movement.

[0038] The installation beam 22 is equipped with a guide slope to prevent powder from accumulating.

[0039] like Figure 4 and Figure 5 As shown, the second anti-arching device 5 includes a supporting beam 51, a mounting shell 52, and a spiral roller 53. The mounting shell 52 is detachably mounted on the supporting beam 51. A drive motor is installed inside the mounting shell 52. The mounting shell 52 encapsulates the drive motor internally to prevent powder from entering the motor, protect the normal operation of the motor, and extend the service life of the motor. The drive end of the drive motor is connected to the spiral roller 53. The spiral roller 53 is mounted in the feeding guide layer 4 through the supporting beam 51. The spiral roller 53 rotates to guide the powder in the feeding guide layer 4 to feed out. At the same time, it keeps the powder in the feeding guide layer 4 in a rotating motion. The rotational motion redisperses the copper-gold powder, avoids arching, and ensures the fluidity of the powder.

[0040] Both the mounting shell 52 and the supporting beam 51 are equipped with material distribution slopes. The powder slope and the guide slope have the same effect. The material distribution slope on the mounting shell 52 cooperates with the material distribution slope on the supporting beam 51 to allow the powder to slide down naturally, reduce the residence time of the powder in these parts, and further enable the powder to flow more smoothly to the screw conveyor 8, thereby improving the material discharge efficiency.

[0041] All parts and equipment use conventional models in the existing technology. In addition, the circuit connection and communication connection adopt conventional connection methods in the existing technology, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0042] Working principle: The staff connects the feed hopper of box 1 to the copper-gold powder feeding pipe to feed the material, and observes whether the feeding is normal through the observation window;

[0043] If the material feeding is slow, the screw lifting device 21 of the first arch-removing device 2 will be activated, thereby driving the main arch-breaking head 23 and the arch-breaking ring 24 into the feed inlet of the box 1 to break the arch and buffer and divert the flow.

[0044] The powder falls onto the spring filter plate 3 for filtration and screening. The powder passing through the spring filter plate 3 is introduced into the screw conveyor 8 via the feeding guide layer 4 for subsequent conveying.

[0045] During the powder feeding process through the spring filter plate 3, the second anti-arching device 5 is in continuous motion. The rotating spiral roller 53 applies stress to the powder, guiding the powder feeding process while preventing the filtered powder from arching again.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
