Description

Technical Field

[0001] This utility model relates to the field of powder processing technology, specifically to a powder surface modifier coating and mixing equipment. Background Technology

[0002] In the processing of powder materials, in order to improve the performance of the powder, it is often necessary to modify the powder surface, that is, to coat the powder surface with a modifier. The process of coating the metallurgical powder surface modifier with the metallurgical powder surface often uses a stirrer. The rotating stirring blades mix the metallurgical powder (such as zinc powder, magnesium powder, calcium oxide and other metal powders or powders of easily deactivated substances or multiple substances) and the modifier evenly to form a passivation layer.

[0003] Based on the above, the following problems were found: In the current powder surface modifier coating and mixing equipment, it is difficult to spray the modifier evenly onto the powder surface during the coating process, often resulting in uneven coating of the modifier and poor modification effect of the powder.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a powder surface modifier coating and mixing equipment in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a powder surface modifier coating and mixing device to solve the problem mentioned in the background art that the modifier is difficult to spray evenly onto the powder surface during the coating process, often resulting in uneven coating of the modifier and poor modification effect of the powder.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A powder surface modifier coating and mixing device includes a mixing tank. Four support frames are installed on the bottom outer side of the mixing tank. A first feed inlet is connected to one side of the top of the mixing tank. A storage tank is located on one side of the mixing tank, and a second feed inlet is connected to the top of the storage tank. A spray plate is located at the top inner side of the mixing tank. Connecting rods are installed on both sides of the top of the spray plate, and the tops of the connecting rods are fixedly connected to the top inner side of the mixing tank. Several atomizing nozzles are installed at the bottom of the spray plate. A stirring shaft is rotatably connected to the top inner side of the mixing tank. The bottom end of the stirring shaft passes through the bottom end of the spray plate. Several first stirring blades are installed on the outer side of the stirring shaft. Several second stirring blades are installed on the inner wall of the mixing tank. A drive mechanism for driving the stirring shaft to rotate is installed at the top of the mixing tank. A liquid supply mechanism for supplying liquid to the spray plate is installed at the top of the mixing tank. A discharge valve is installed at the bottom of the mixing tank.

[0008] Furthermore, the drive mechanism includes a speed reducer, the bottom end of which is fixedly connected to the top end of the mixing tank. A motor is installed on one side of the speed reducer, the output end of which is connected to the input end of the speed reducer, and the output end of the speed reducer is connected to the top end of the mixing shaft.

[0009] The beneficial effects of adopting the above-mentioned further solution are that by connecting the motor and the stirring shaft through the reducer of the drive mechanism, the speed is reduced and the torque is increased, avoiding excessive powder resistance that could cause motor overload. At the same time, the speed of the stirring shaft is precisely controlled to adapt to different powder stirring requirements, ensuring that the first stirring blade evenly tumbles the powder and improving the stability of the modifier coating effect.

[0010] Furthermore, the liquid delivery mechanism includes a metering pump, the bottom of which is fixedly connected to the top of the mixing tank. A liquid extraction pipe is installed at the input end of the metering pump, one end of which extends to the bottom of the storage tank. A liquid delivery pipe is installed at the output end of the metering pump, one end of which is connected to the input end of the spray plate.

[0011] The beneficial effects of adopting the above-mentioned further solution are that the modifier is drawn from the storage tank by the metering pump of the liquid delivery mechanism through the liquid extraction pipe and quantitatively delivered to the spray plate by the liquid delivery pipe. The amount of modifier is precisely controlled, and the stable delivery pressure ensures that the atomizing nozzle continuously atomizes and sprays out the modifier, so that the modifier evenly covers the powder surface, reducing waste and ensuring coating quality.

[0012] Furthermore, a heating jacket is installed on the outside of the mixing tank, and an electric heating wire is provided inside the heating jacket.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by installing a heating jacket on the outside of the mixing tank, the heating jacket can be heated by an electric heating wire, which can provide a suitable temperature for the mixing process, promote the chemical reaction or physical adsorption between the modifier and the powder surface, and improve the modification effect.

[0014] Furthermore, a first cap is installed at the top of the first feed inlet, and a second cap is installed at the top of the second feed inlet.

[0015] The beneficial effects of adopting the above-mentioned further solution are that the feeding channel can be sealed by the first cap of the first feed port and the second cap of the second feed port, preventing powder from flying or external impurities from entering during stirring, while reducing the volatilization of modifiers and ensuring a clean production environment and the purity of raw materials.

[0016] Furthermore, a support plate is installed at the bottom of the support frame, and the bottom of the support plate is provided with anti-slip texture.

[0017] The beneficial effect of adopting the above-mentioned further solution is that by increasing the grounding area through the support plate at the bottom of the support frame, and enhancing the friction through the anti-slip texture at the bottom, the equipment is prevented from shifting during stirring and vibration, ensuring the stable operation of the stirring shaft and the spray plate, and improving the safety of the equipment.

[0018] Furthermore, a control panel is installed on the top of the mixing tank.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the motor speed, metering pump flow rate and heating jacket temperature can be integrated and controlled through the control panel at the top of the mixing tank, thereby realizing intelligent regulation of the modification process.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This powder surface modifier coating and mixing equipment provides a closed mixing space through a mixing tank, a support frame stably supports the tank, the first and second inlets facilitate the addition of powder and modifier respectively, a connecting rod fixes the spray plate, and an atomizing nozzle evenly sprays the modifier. The mixing shaft drives the first mixing blade to rotate, which, in conjunction with the second mixing blade, enhances powder agitation and ensures thorough coating of the modifier. The drive mechanism provides mixing power, the liquid delivery mechanism provides precise liquid supply, and the discharge valve controls the discharge of the finished product. The reducer of the drive mechanism connects the motor and the mixing shaft, reducing the speed and increasing the torque to avoid excessive powder resistance causing motor overload. At the same time, it precisely controls the speed of the mixing shaft to adapt to different powder mixing needs, ensuring that the first mixing blade evenly agitates the powder and improves the stability of the modifier coating effect. The metering pump of the liquid delivery mechanism draws the modifier from the storage tank through the liquid extraction pipe and quantitatively delivers it to the spray plate through the liquid delivery pipe, precisely controlling the amount of modifier used. Stable delivery pressure ensures the atomization of the powder. The spray nozzle continuously atomizes and sprays the modifier, ensuring uniform coverage of the powder surface, reducing waste and guaranteeing coating quality. A heating jacket installed on the outside of the mixing tank, heated by an electric heating wire, provides a suitable temperature for the mixing process, promoting chemical reaction or physical adsorption between the modifier and the powder surface, thus enhancing the modification effect. A first cap at the first feed inlet and a second cap at the second feed inlet seal the feed channels, preventing powder from flying or external impurities from entering during mixing, while also reducing modifier volatilization, ensuring a clean production environment and raw material purity. A support plate at the bottom of the support frame increases the ground contact area, and its anti-slip texture enhances friction, preventing equipment displacement during mixing vibrations and ensuring stable operation of the mixing shaft and spray plate, improving equipment safety. A control panel at the top of the mixing tank integrates control of motor speed, metering pump flow, and heating jacket temperature, enabling intelligent adjustment of the modification process. This invention effectively achieves integrated coating and mixing, improving modification efficiency and uniformity, and has high practical value. Attached Figure Description

The inner wall of the mixing tank 1 is equipped with several second stirring blades 10. The top of the mixing tank 1 is equipped with a drive mechanism 7 for driving the stirring shaft 8 to rotate. The top of the mixing tank 1 is equipped with a liquid delivery mechanism 5 for supplying liquid to the spray plate 11. The bottom of the mixing tank 1 is equipped with a discharge valve 14. The mixing tank 1 provides a closed stirring space. The support frame 2 stably supports the tank body. The first feed port 101 and the second feed port 601 facilitate the addition of powder and modifier, respectively. The connecting rod 12 fixes the spray plate 11. The atomizing nozzle 1101 sprays the modifier evenly. The stirring shaft 8 drives the first stirring blade 9 to rotate, which cooperates with the second stirring blade 10 to enhance the tumbling of the powder and ensure that the modifier is fully coated. The drive mechanism 7 provides stirring power, the liquid delivery mechanism 5 supplies liquid accurately, and the discharge valve 14 controls the discharge of the finished product.

[0030] Please see Figures 1-5 The drive mechanism 7 includes a reducer 701, the bottom of which is fixedly connected to the top of the mixing tank 1.

A delivery pipe 502 is mounted on the output end of the metering pump 501, one end of which is connected to the input end of the spray plate 11. The connection is made by connecting the motor 702 and the stirring shaft 8 through the reducer 701 of the drive mechanism 7, which reduces the speed and increases the torque to avoid excessive powder resistance causing motor overload. At the same time, the speed of the stirring shaft is precisely controlled to adapt to different powder stirring requirements, ensuring that the first stirring blade 9 evenly tumbles the powder and improves the stability of the modifier coating effect.

This promotes the chemical reaction or physical adsorption of the modifier on the powder surface, improving the modification effect. The first cover 102 and the second cover 602 of the second feed inlet 601 can seal the feed channel to prevent powder from flying or external impurities from entering during stirring, while reducing the volatilization of modifiers, ensuring a clean production environment and the purity of raw materials. The support plate 3 at the bottom of the support frame 2 increases the grounding area, and its anti-slip texture at the bottom enhances friction, preventing the equipment from shifting during stirring vibration, ensuring the stable operation of the stirring shaft 8 and the spray plate 11, and improving equipment safety.
