Description

Technical Field

[0001] The utility model relates to the field of powder material charging barrels, in particular to a powder material charging barrel. Background Art

[0002] In the traditional powder metallurgy industry, most companies' powder materials are stored in stainless steel barrels. When using materials, employees need to lift the barrel onto the weighing table and then use a shovel to shovel out the required materials. This process is time-consuming and labor-intensive. At the same time, since the barrel needs to be open when loading, this will increase the risk of material contamination. In addition, some fine-grained powders cannot be exposed to air for a long time, and ordinary stainless steel barrels are obviously not suitable. To solve the above problems, as in patent JPH1046205A, the mesh is set at the input hole of the hopper, and the powder on the mesh is vibrated to fall off. However, there are problems such as no sealing and inability to move. Utility Model Content

[0003] In order to solve the problem of no sealing and inability to move, a powder loading barrel was invented which is sealed, easy to move and can unload materials quickly.

[0004] A powder loading barrel, the loading cavity includes an upper feeding port and a lower feeding port, a sealing cover is arranged on the feeding port, and an air vibrator is arranged at the feeding port; the loading cavity is movably arranged by a moving device. The sealing cover and the loading cavity can form a sealing structure to ensure that the air inside the cavity is not exchanged with the external environment; the inside of the loading cavity is used to hold the powder; the air vibrator plays a role of vibration, and when it is difficult to discharge the material, the air vibrator is started to accelerate the falling of the powder and improve the work efficiency; the moving device undertakes the role of moving the device, which is convenient for movement and saves manpower and material resources.

[0005] Preferably, a sealing strip is provided on the upper edge of the loading cavity; a number of evenly distributed sealing buckles are provided on the outer circumference of the upper part of the loading cavity, and the sealing cover and the loading cavity are sealed when the sealing buckles are fastened. The upper edge of the loading cavity is in contact with the sealing cover, and the gap between the two is filled by the sealing strip. When the sealing cover is covered, a sealed environment can be formed, isolating the exchange of air inside and outside the loading cavity; a number of sealing buckles are provided on the loading cavity, which can ensure the tightness of the seal and the firmness of the device when it is closed; the even distribution of the sealing buckles ensures that the force exerted on each sealing buckle is the same, avoiding the situation where a certain position is subjected to excessive force.

[0006] Preferably, the charging cavity is in the shape of a funnel as a whole; a pneumatic valve is installed in the discharge port. The funnel-shaped charging cavity is used to hold powders, and the lower part has an inclination to collect the powders to the discharge port; a pneumatic valve is installed in the discharge port to control the opening of the discharge port, thereby controlling the falling of the powders.

[0007] Preferably, the sealing cover is matched with the charging cavity; the sealing cover is in the shape of a round arch. Because the sealing cover and the charging cavity are to isolate the inside of the device from the outside when they are closed, the sizes of the two should be matched; the round arch shape makes the sealing cover strong in pressure bearing ability, strong and durable, and also increases the volume of the device to a certain extent, facilitating the introduction of compressed gas.

[0008] Preferably, a compressed gas inlet is provided on the sealing cover; an inlet valve is installed on the compressed gas inlet. The compressed inert gas introduced from the compressed gas inlet can not only protect the powder stored in the charging cavity from oxidation or contamination, but also accelerate the falling of the powder, because there is a pressure difference between the upper and lower parts, thus improving the working efficiency; the inlet valve can control the opening and closing of the compressed gas inlet, and the sealing of the device will not be affected by the compressed gas inlet.

DETAILED DESCRIPTION

[0017] Embodiment 1:

[0018] As the instruction manual Figure 1 , 2 , 3, a powder loading barrel includes a loading chamber, the loading chamber includes an upper feeding port and a lower feeding port 4, a sealing cover is arranged on the feeding port, and a gas vibrator is arranged at the feeding port; the loading chamber is movably arranged by a moving device. The loading chamber 1 is funnel-shaped as a whole, with a feeding port 4 at the lower part, and a sealing cover 6 is hinged on the upper opening of the hollow cylinder; a sealing strip 11 is installed on the upper opening of the loading chamber, and the sealing strip fills the gap between the sealing cover and the upper opening of the loading chamber to play a sealing role; two sealing buckles 10 are arranged on the outer circumference of the loading chamber; when the sealing cover is closed, the sealing buckles are buckled to ensure the sealing of the device; a compressed gas inlet 12 is arranged on the sealing cover, and an inlet valve 5 is arranged on the inlet. The compressed gas inlet is used to fill inert gas, which is supplied by the inlet. The air valve is controlled to open; a pneumatic vibrator 2 is installed at the lower part of the loading chamber, and a pneumatic valve 3 is installed at the discharge port; a pneumatic vibrator switch 8 and a pneumatic valve switch 9 are installed outside the loading chamber; the pneumatic vibrator switch controls the pneumatic vibrator to control whether vibration is generated to facilitate discharge; the pneumatic valve switch controls the pneumatic valve to control whether to discharge; a moving device 14 is arranged outside the loading chamber to facilitate the device to move quickly and labor-savingly; the moving device has two connecting columns 13, one end of which is connected to the loading chamber and the other end is connected to the roller 7, so that the entire device can be moved.

[0019] During the loading process, the sealing cover 6 on the loading chamber 1 is opened, and the powder is loaded into the chamber. After loading, the sealing cover is covered, the sealing buckle 10 is tightened, and the powder is sent to the material warehouse for storage. In order to ensure that the powder is polluted by the air as little as possible, the air inlet valve 5 can be opened, and the compressed gas inlet 12 can be filled with inert gas. When the material is to be taken, the device is pushed, and the roller 7 rolls and moves to the weighing place. The roller facilitates transportation. The weighing hopper is placed directly below the discharge port 4, and compressed air is introduced into the compressed gas inlet. The pneumatic valve 3 controlling the discharge port can be opened by turning the pneumatic valve switch 9, and the powder inside the device can flow into the weighing hopper by its own gravity. If the powder cannot fall due to agglomeration, the pneumatic vibrator switch 8 is turned on to make the pneumatic vibrator 2 work, generate vibration, break up the agglomerates, and enhance the fluidity of the powder, thereby achieving the purpose of rapid discharge.

[0020] The material of the charging chamber 1 can be stainless steel, and the inside of the chamber is inlaid with mirror stainless steel. The use of mirror stainless steel can not only reduce the friction between the inside of the chamber and the powder, so that the powder can slide down to the discharge port as quickly as possible, but also facilitate cleaning, and it is difficult for dirt to accumulate on the smooth inner wall of the chamber. The stainless steel material ensures the overall structural strength of the charging chamber; it is low in cost, saves production costs; it is durable and has a long service life.

[0021] The shape of the loading cavity 1 is funnel-shaped, and the upper part is a smooth hollow cylinder. Among the cylindrical loading cavities made of equal materials, the hollow cylinder can load the most powder, and is easy to process and produce, without corners, avoiding the problem of stress concentration, ensuring that the pressure at various locations is balanced, and there are no weak points of force, thereby extending the service life; the lower part is a smooth hollow inverted cone, which plays the role of collecting powder. It has a certain slope and can collect the powder to the discharge port during the falling process, which plays a role in facilitating the discharge; the shape of the cone also has no corners and no weak points of force. The thickness of the loading cavity is uniform everywhere, and the material is of equal thickness. There should be no gaps in the material of the device, which will affect the overall sealing of the device and cause powder leakage.

[0022] The diameter of the lower end of the sealing cover 6 is the same as the diameter of the upper half of the charging chamber 1, so there will be no problems of air leakage and poor sealing due to size mismatch; the sealing cover is arched, which effectively disperses the pressure and prolongs the service life of the sealing cover. The material can be stainless steel, which is cheap and has sufficient structural strength. The sealing cover also plays a role in preventing powder leakage.

[0023] The arched sealing cover also increases the volume of the device, so that more powder can be loaded; the arched shape also facilitates the entry of compressed gas from the sealing cover, forming a relatively high pressure above the device, creating an air pressure difference with the outside air, so that the powder at the discharge port can fall quickly, thereby speeding up the discharge.

[0024] The gas vibrator 3 can be selected from GT-10 to GT-30, which can generate a vibration force of 2000-3000N under a pressure of 0.2Mpa. This vibration force is sufficient to cause the powder to move. Secondly, excessive vibration force can easily cause damage to the loading cavity 1, causing dents, affecting the natural fall of the powder, and even causing cracks, which not only affects the sealing of the device, but also shortens the service life of the device.

[0025] The sealing strip 11 fills the gap between the upper opening of the charging cavity 1 and the sealing cover 6, and plays the role of shock absorption, waterproofing, dustproofing, sound insulation, heat insulation, dustproofing, fixing, etc. The material of the sealing strip can be rubber, paper, metal, and plastic. In the use of the utility model, the air inside and outside the charging cavity is isolated, and the external air is prevented from entering the charging cavity, and the powder loaded inside is prevented from being polluted. Using a rubber strip as a sealing strip can effectively play a sealing and isolating role. The price of rubber is low, which can reduce the cost of the device; silicone material can also be selected.

[0026] The outer diameter of the sealing strip is adapted to the outer diameter of the cylinder in the upper half of the loading cavity, so that when the sealing cover is closed, the air inside the cavity cannot circulate with the air in the external environment, thereby ensuring the internal airtightness.

[0027] When the air inlet valve 5 is opened and compressed inert gas is introduced into the compressed gas inlet 12, a high-pressure environment is formed above the powder, and the pressure is higher than the standard atmospheric pressure below the powder, so that the powder can be pressed toward the lower feed port 4, thereby accelerating the discharge efficiency.

[0028] The inert gas introduced can be nitrogen or argon. Under the protection of the inert gas, the metal powder loaded inside will not be polluted by the air, preventing the occurrence of oxidation reaction and changing the chemical properties of the powder. The risk of oxidation, combustion and explosion can be reduced to a minimum because the inert gas will not react chemically with the powder.

[0029] The upper ends of the two connecting columns 14 are welded to the charging cavity, and the welding position is between the hollow cylinder and the inverted truncated cone. The slope is consistent with the slope of the inverted truncated cone, which ensures the strength of the connection and is relatively smooth, thereby enhancing the safety of the use of the utility model. The roller 7 is installed at the lower end, so that the entire device can be moved with less force. The connecting column can be a solid stainless steel column to ensure that it has sufficient structural strength. The two connecting columns are spaced 180° apart to ensure the stability of the utility model.

[0030] The two sealing buckles 10 on the charging cavity 1 are arranged at an interval of 180°. The consistent interval ensures the relative connection strength and prevents individual positions from being easily deformed by force.

[0031] The roller structure is provided, so that the pushing of the device is labor-saving and convenient to move, which saves the user's physical strength and makes the work more efficient because of the convenience of movement.

[0032] In order to achieve a better vibration effect, the gas vibrator 2 is installed in the lower half of the charging chamber 1. The lower half is close to the discharge port 4, and the powder can be effectively vibrated off near the vibrator.

[0033] The pneumatic vibrator switch and the pneumatic valve switch are arranged outside the charging cavity, and can be arranged on a platform, the height of which is suitable for user operation; or they can be directly arranged on the barrel wall outside the charging cavity.

[0034] The use of a sealed structure can reduce dust and protect the safety of users; using vibration instead of stirring and falling can avoid the problem of dust; at the same time, the vibration mechanism only requires an air vibrator and an air vibrator switch, which are arranged on the outside of the charging chamber for easy maintenance and replacement, while the stirring equipment is arranged on the inside of the charging chamber, which is not only difficult to maintain and replace, but also increases the temperature of the powder during rapid stirring, affecting the quality of the powder itself; high temperature will also make the powder more likely to stick together, which is contrary to the original intention of dispersing the powder and accelerating the falling; accelerating the falling of the powder by vibration not only does not generate a lot of heat, but also has a simpler structure, which is convenient for production and processing, and the specifications of the air vibrator can be directly replaced according to actual conditions.

[0037] The pneumatic valve 3 of the discharge port 4 can also be an electric valve. The electric valve can form a linkage device with the weight sensor of the electronic scale. Before discharging, the weight value is set, and the electric valve is opened for discharging. When the weight reaches the set value, the electric valve can be automatically closed, thereby reducing the operation of employees. The use of the electric valve and the weight sensor can limit the amount of material discharged to prevent the powder from overflowing the subsequent loading barrel; with the mobile device, the material can be discharged without overflow.

[0038] The number of connecting columns 14 can also be four, with a 90° interval between each two, and the material and height of each connecting column are the same; the more connecting columns there are, the heavier the powder weight that the overall device can bear; the uniform spacing can ensure the force balance of the utility model and prevent rollover; the same height of each connecting column can ensure that the force on each connecting column is equal.

[0039] The number of sealing buckles 10 can also be four, with two of them spaced 90 degrees apart.
