Description

Technical Field

[0001] This utility model belongs to the field of cobalt-chromium fine powder processing technology, and in particular relates to a collection device for cobalt-chromium fine powder. Background Technology

[0002] Cobalt-chromium fine powder, due to its excellent high-temperature resistance, corrosion resistance, and mechanical strength, is increasingly widely used in aerospace, medical devices, and high-end machinery manufacturing. The collection process directly impacts product quality, production costs, and the production environment. Currently, most cobalt-chromium fine powder collection equipment uses a traditional fixed-feed structure, directly introducing the fine powder into the collection bag through a single inlet. This lack of effective diversion and dynamic spreading design leads to numerous prominent problems during the collection process.

[0003] The existing equipment has a fixed feed inlet position and no diversion function. Under the influence of gravity, the cobalt-chromium fine powder always falls into the middle of the collection bag, forming local accumulation. This concentrated accumulation firstly leads to extremely uneven stress on the collection bag. The middle part is subjected to the gravitational compression of the fine powder for a long time, which makes the bag material prone to stretching and breakage. This not only causes leakage and waste of valuable cobalt-chromium fine powder, but also increases the frequency of collection bag replacement and production costs. In addition, the bottom of the collection bag of the collection equipment is mostly a fixed support structure. During the initial feeding, the fine powder falls from a height to the bottom of the collection bag, which easily generates a lot of dust. The cobalt-chromium fine powder particles are small and easily suspended, which not only pollutes the production environment, but may also be inhaled by operators, endangering their respiratory health.

[0004] To address these issues, we provide a collection device for cobalt-chromium fine powder. Utility Model Content

[0005] The purpose of this invention is to provide a collection device for cobalt-chromium fine powder. Through the action of a distribution pipe, a motor drives the distribution pipe and discharge pipe to rotate. The cobalt-chromium fine powder is diverted through the distribution pipe and then evenly distributed into the fine powder collection bag through the rotating discharge pipe. This prevents the fine powder from accumulating in a concentrated area within the collection bag, ensuring balanced stress on the bag, reducing the risk of breakage, and avoiding the problem of compaction and agglomeration caused by localized accumulation. This solves the problem of existing equipment with a fixed inlet position and no diversion function, where the cobalt-chromium fine powder always falls concentrated in the middle of the collection bag under gravity, forming localized accumulation. This concentrated accumulation firstly leads to extremely uneven stress on the collection bag, with the middle section constantly subjected to the gravitational pressure of the fine powder, making the bag material prone to stretching and breakage. This not only causes leakage and waste of valuable cobalt-chromium fine powder but also increases the frequency of collection bag replacement and production costs.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a collection device for cobalt chromium fine powder, including a collection box, and a positioning ring is fixed on the top of the collection box;

[0007] The top of the collection box is movably connected to a cover plate, and mounting plates are fixed on both sides of the cover plate;

[0008] The mounting plate and the positioning ring are fixedly connected by bolts;

[0009] The top of the cover plate has a movable groove, and the bottom of the cover plate is fixed with a connecting rod, one end of which is fixed with a positioning plate.

[0010] A motor is fixed to the top of the positioning plate, and a support rod is fixed to the output shaft of the motor.

[0011] One end of the support rod is fixed with a material distribution pipe, the top of the material distribution pipe is fixed with a material inlet pipe, and the top of the material inlet pipe is fixed with a material inlet.

[0012] Both ends of the distribution pipe are fixed with discharge pipes, and a support plate is fixed between the discharge pipe and the distribution pipe. The support plate slides on the upper surface of the cover plate.

[0013] The present invention is further configured such that: a plurality of buffers are fixed at the bottom of the collection box, and the buffers include buffer shells;

[0014] The buffer shell is fixedly connected to the bottom of the collection box;

[0015] A telescopic rod is fixed inside the buffer shell, and a connecting plate is fixed to one end of the telescopic rod.

[0016] The present invention is further configured such that: a fixing rod is fixed to the top of the connecting plate, and a support ring is fixed to one end of the fixing rod;

[0017] Several reinforcing plates are fixed to the inner wall of the support ring;

[0018] A spring is fixed between the buffer shell and the connecting plate, and several limiting rods are fixed at the bottom of the support ring.

[0019] The present invention is further configured such that: an air extraction port is fixed at the bottom of the collection box, and the air extraction port is connected to a filter box through a first air pipe;

[0020] The filter box is connected to an air pump via a second air pipe.

[0021] The present invention is further configured such that: a plurality of limiting plates are fixed inside the filter box, and filter plates are slidably connected inside the limiting plates;

[0022] A top plate is fixed to the top of the filter plate, and the top plate is fixedly connected to the filter box by bolts.

[0023] The present invention is further configured such that: a plurality of threaded tubes are fixed on the surface of the positioning ring, and a threaded rod is threadedly connected inside the threaded tubes.

[0024] The present invention is further configured such that: a handle is fixed to one end of the threaded rod, and a pressure plate is fixed to the end of the threaded rod away from the handle;

[0025] Several anti-slip blocks are fixed to the surface of the pressure plate.

[0026] This utility model has the following beneficial effects:

[0027] 1. This utility model utilizes the function of the distribution pipe. The motor drives the distribution pipe and the discharge pipe to rotate. After the cobalt chromium fine powder is diverted by the distribution pipe, it is evenly sprinkled into the fine powder collection bag by the rotating discharge pipe. This prevents the fine powder from accumulating in a localized area of ​​the fine powder collection bag, ensuring that the fine powder collection bag is subjected to balanced force, reducing the risk of breakage, and avoiding the problem of fine powder compaction and clumping caused by local accumulation.

[0028] 2. This utility model utilizes the buffer's function. The buffer's support ring provides stable support to the bottom of the fine powder collection bag. As the weight of the cobalt-chromium fine powder increases, the spring is compressed, causing the support ring and the fine powder collection bag to descend slowly and synchronously. This dynamically adjusts the distance between the fine powder collection bag and the discharge pipe, preventing excessive dust generation due to excessive falling height. The telescopic rod, in conjunction with the spring, achieves smooth lifting and lowering, while the limiting rod restricts the descent range of the support ring, preventing excessive downward movement of the support ring and damage to the bottom of the fine powder collection bag, further reducing dust and fine powder waste.

Specific Implementation Example 1

[0042] Please see Figures 1-6 This utility model is a collection device for cobalt-chromium fine powder, including a collection box 1, a positioning ring 2 fixed on the top of the collection box 1; a cover plate 3 movably connected to the top of the collection box 1, and mounting plates 4 fixed on both sides of the cover plate 3; the mounting plates 4 and the positioning ring 2 are fixedly connected by bolts; a movable groove 5 is opened on the top of the cover plate 3, a connecting rod 6 is fixed to the bottom of the cover plate 3, and a positioning plate 7 is fixed to one end of the connecting rod 6; a motor 8 is fixed to the top of the positioning plate 7, and a support rod 9 is fixed to the output shaft of the motor 8; a distribution pipe 10 is fixed to one end of the support rod 9, a feed pipe 11 is fixed to the top of the distribution pipe 10, and a feed inlet 12 is fixed to the top of the feed pipe 11; a discharge pipe 13 is fixed to both ends of the distribution pipe 10, and a support plate 14 is fixed between the discharge pipe 13 and the distribution pipe 10, and the support plate 14 slides on the upper surface of the cover plate 3.

[0043] Specifically, a number of buffers 15 are fixed at the bottom of the collection box 1. Each buffer 15 includes a buffer shell 16. The buffer shell 16 is fixedly connected to the bottom of the collection box 1. A telescopic rod 17 is fixed inside the buffer shell 16. A connecting plate 18 is fixed at one end of the telescopic rod 17.

[0044] Furthermore, a fixing rod 19 is fixed to the top of the connecting plate 18, and a support ring 20 is fixed to one end of the fixing rod 19; several reinforcing plates 21 are fixed to the inner wall of the support ring 20; a spring 22 is fixed between the buffer shell 16 and the connecting plate 18, and several limiting rods 23 are fixed to the bottom of the support ring 20.

[0045] The operation process of this embodiment is as follows: Before using this device, first open the cover plate 3 on the top of the collection box 1, put the fine powder collection bag into the collection box 1, fold the edge of the collection bag opening outwards, and put it on the outside of the positioning ring 2 on the top of the collection box 1 to ensure that the opening is fully open. Hold the handle 32 at one end of the threaded rod 31 and rotate the threaded rod 31 clockwise so that it moves downwards in the threaded tube 30 on the positioning ring 2. The threaded rod 31 drives the pressure plate 33 and the anti-slip block 34 on the surface to move downwards simultaneously until the pressure plate 33 tightly presses the edge of the collection bag. The anti-slip block 34 enhances the friction and prevents the collection bag from falling off or shifting. Then close the cover plate 3 on the collection box. At the top of the collection box 1, align the corresponding holes of the mounting plates 4 and positioning rings 2 on both sides of the cover plate 3, and tighten the bolts through the holes of the mounting plates 4 and positioning rings 2 to ensure that the cover plate 3 and the collection box 1 are sealed and fitted. Start the motor 8, and the output shaft of the motor 8 drives the support rod 9 to rotate, which in turn drives the distribution pipe 10 and the discharge pipes 13 at both ends to rotate synchronously. Slowly pour cobalt chromium fine powder into the inlet 12 at the top of the cover plate 3. The fine powder enters the inverted U-shaped distribution pipe 10 through the inlet pipe 11 and is evenly distributed to the discharge pipes 13 on both sides. The rotating discharge pipe 13 evenly sprinkles the fine powder into the collection bag below, avoiding the fine powder from accumulating in a certain area of ​​the collection bag. As fine powder is continuously added, the weight of the collection bag gradually increases, pressing down on the support ring 20. The support ring 20, through the fixed rod 19, causes the connecting plate 18 to move downward, compressing the spring 22 between the buffer shell 16 and the connecting plate 18. The telescopic rod 17 contracts synchronously, and the collection bag descends slowly with the support ring 20, always maintaining a reasonable distance from the discharge pipe 13 to reduce dust. In this device, the motor 8 drives the distribution pipe 10 and the discharge pipe 13 to rotate. After being diverted by the distribution pipe 10, the cobalt-chromium fine powder is evenly sprinkled into the fine powder collection bag through the rotating discharge pipe 13, preventing the fine powder from accumulating locally in the fine powder collection bag, thus ensuring the fine powder collection bag is under stress. The system balances and reduces the risk of breakage while avoiding the problem of fine powder compaction and clumping caused by local accumulation. At the same time, the support ring 20 of the buffer 15 provides stable support to the bottom of the fine powder collection bag. As the weight of the cobalt chromium fine powder increases, the spring 22 is compressed, causing the support ring 20 and the fine powder collection bag to descend slowly and synchronously. This dynamically adjusts the distance between the fine powder collection bag and the discharge pipe 13, preventing the fine powder from generating a large amount of dust due to excessive falling height. The telescopic rod 17 works with the spring 22 to achieve smooth lifting and lowering. The limit rod 23 restricts the descent range of the support ring 20, preventing the support ring 20 from moving too far down and causing damage to the bottom of the fine powder collection bag, further reducing dust and fine powder waste. Specific Implementation Example 2

[0047] Please see Figures 1-6Based on the first specific embodiment, the bottom of the collection box 1 is fixed with an air extraction port 24, and the air extraction port 24 is connected to the filter box 25 through a first air pipe; the filter box 25 is connected to the air pump 26 through a second air pipe; a number of limiting plates 27 are fixed inside the filter box 25, and filter plates 28 are slidably connected inside the limiting plates 27; a top plate 29 is fixed on the top of the filter plate 28, and the top plate 29 is fixedly connected to the filter box 25 by bolts.

[0048] Specifically, the surface of the positioning ring 2 is fixed with several threaded tubes 30, and the threaded tubes 30 are internally connected with threaded rods 31.

[0049] Furthermore, a handle 32 is fixed to one end of the threaded rod 31, and a pressure plate 33 is fixed to the end of the threaded rod 31 away from the handle 32; several anti-slip blocks 34 are fixed to the surface of the pressure plate 33.

[0050] The operation process of this embodiment is as follows: After the feeding begins, the vacuum pump 26 is started synchronously. The vacuum pump 26 draws gas from the collection box 1 through the second air pipe, the filter box 25, the first air pipe, and the air extraction port 24, forming a slight negative pressure in the collection box 1, so that the bottom of the collection bag fits more tightly against the support ring 20, preventing fine powder from scattering; a small amount of fine powder that overflows enters the filter box 25 with the airflow and is intercepted and collected by the filter plate 28 in the limiting plate 27. After the cobalt chromium fine powder feeding is completed, the motor 8 and the vacuum pump 26 are kept running for several minutes to ensure that the remaining fine powder in the collection box 1 falls completely into the collection bag or is collected by the filter plate 28. The motor 8 and the vacuum pump 26 are then turned off, and the cover plate 3 is removed from the connection between the cover plate 3 and the positioning ring 2. Remove the bolts, take off the cover plate 3, turn the handle 32 counterclockwise to loosen the pressure plate 33, take out the collection bag containing fine powder and seal it, unscrew the bolts on the top plate 29 of the filter box 25, pull out the filter plate 28, clean the fine powder collected on the surface and then recycle it. In this device, the air pump 26 draws gas from the collection box 1 through the air intake port 24 to create a slight negative pressure inside the box. On the one hand, this allows the bottom of the collection bag to fit more tightly against the support ring 20, reducing the space for fine powder to drift inside the box and reducing the amount of dust. On the other hand, it can introduce a small amount of overflowing fine powder into the filter box 25 with the airflow, and intercept and recycle it by the filter plate 28 supported by the limiting plate 27. This avoids the waste of cobalt chromium fine powder and prevents the emission of fine powder from polluting the environment.
