Description

Technical Field

[0001] The utility model belongs to the technical field of material mixing, in particular to a rotary driven powder mixing device. Background Art

[0002] Powders generally refer to solid substances with tiny particles, such as flour, corn flour, wheat flour, etc. It also includes a variety of powdered chemical raw materials, food additives, pharmaceutical raw materials, etc. Powders are widely used because they are easy to store, transport and use. At the same time, due to their tiny particles, they can increase the surface area of ​​materials, improve the reaction speed and efficiency of materials. Therefore, powders are widely used in manufacturing industry, food industry, chemical industry, pharmaceutical industry and other fields. In the process of powder processing, multiple powders are often mixed to prepare the required products. When the powders are mixed, they are often processed by rotary driven powder mixing equipment to improve the mixing efficiency of the powders. However, it still has the following disadvantages in actual use:

[0003] The utility model with publication number CN217568388U discloses a powder mixing device, wherein an adjusting rod is coaxially arranged with a tank body, and the adjusting rod is slidably connected with the tank body; a scraping frame is rotatably connected with the adjusting rod, and the scraping frame can scrape off the powder on the inner wall of the tank body; a linkage rod is arranged on the scraping frame, and a stirring mechanism can drive the linkage rod to rotate around the adjusting rod. The powder mixing device usually stirs and mixes a variety of powders by a stirring rod or a stirring blade, but since most of the various powders are poured into the tank body in sequence, upper and lower layers appear between the various powders, and the stirring blade usually stirs in a horizontal direction, it is difficult to quickly stir a large amount of powders evenly;

[0004] When powder is poured into the mixing equipment, it is often mixed with a certain amount of air. There may be a certain amount of moisture in the air. When the powder collides with the stirring blades during stirring, it often increases the temperature inside the equipment. At this time, the powder may react when it comes into contact with the hot and humid air, reducing the quality of the finished product. Utility Model Content

[0005] The utility model aims to provide a rotary driven powder mixing device, which solves the problem that most rotary driven powder mixing devices mix powders by stirring through a mixing tank and a top cover, but a variety of powders are often poured into the device in sequence, with upper and lower layers, and a stirring structure rotating in the horizontal direction is difficult to quickly and evenly stir a large amount of powders, and the powders and the high-speed rotating stirring structure continuously collide to generate a large amount of heat, and the air in the device may contain moisture, and the powders may react when they come into contact with the hot and humid air.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a rotary driven powder mixing device, comprising a mixing tank and a rotary top cover, wherein an electromagnetic conveying pipe is fixedly connected in the center of the mixing tank, a plurality of partition plates are arranged on the outer peripheral surface of the electromagnetic conveying pipe, a top cover is rotatably connected to the top of the mixing tank, a rotary motor is fixedly connected to the center of the top of the top cover, and a dispersing blade and a spiral conveying assembly are arranged from top to bottom at the bottom of the top cover;

[0008] Multiple powders poured into the mixing tank can be separated by multiple partitions to avoid stratification of the multiple powders in the vertical direction. The staff can place multiple partitions at appropriate positions according to the type and amount of powders to control the size of the separation space, thereby improving the flexibility of use. When mixing the powders, the isomorphic high-pressure pump can evacuate the mixing tank to make the mixing tank relatively vacuum to avoid contact between moisture in the air and the powders. The powders fall to the bottom of the mixing tank under the action of gravity. The rotating motor drives the rotation of the dispersion blades and the spiral conveying assembly, so that the powders can continuously enter the bottom of the electromagnetic conveying pipe and move upward along the electromagnetic conveying pipe. After the powders move to the top of the electromagnetic conveying pipe, the mixed powders are broken up by the rotation of the dispersion blades, so that a small amount of powders are fully mixed in a relatively open space, and fall again to the space outside the electromagnetic conveying pipe in the mixing tank under the action of gravity. The mixing efficiency is high, and there is basically no collision and friction when the powders are transported and when the powders are located between the electromagnetic conveying pipe and the mixing tank, thereby avoiding the heating of the powders and ensuring the quality of the powders.

[0009] Furthermore, one end of each of the partition plates is clamped and fixed with an adsorption plate, the adsorption plate is attached to the outer peripheral surface of the electromagnetic conveying pipe, and the other end of the partition plate relative to the adsorption plate is attached to the inner wall of the mixing tank;

[0010] Multiple partitions can be used to separate the various powders poured into the mixing tank to avoid vertical stratification of the various powders. The staff can place multiple partitions at appropriate positions according to the type and amount of powders, control the size of the partition space, and improve the flexibility of use. By energizing the electromagnetic conveying tube to adsorb the adsorption plate, the partition plate can remain stable when the equipment is working.

[0011] Furthermore, a high-pressure pump is welded through the top of the outer peripheral surface of the mixing tank, an exhaust pipe is welded through the top of the outer peripheral surface of the high-pressure pump, a discharge pipe is welded through the center of the bottom of the mixing tank, and the electromagnetic delivery pipe is suspended from the top of the discharge pipe;

[0012] After all the powders are poured into the mixing tank, the mixing tank is evacuated by a high-pressure pump to make the mixing tank in a relative vacuum. This can prevent the powders from coming into contact with moisture in the air when they are broken up, thus ensuring the quality of the powders.

[0013] Furthermore, a feed pipe is welded through the top edge of the top cover, and a hopper is welded through the top of the feed pipe;

[0014] By rotating the top cover, the feed pipe can be moved to different positions, making it convenient to pour a variety of powders into different separated spaces in the mixing tank.

[0015] Furthermore, a rotating rod is clamped at the bottom of the rotating motor, the spiral conveying assembly and the dispersion blades are clamped and fixed to the outer circumferential surface of the rotating rod, the rotating rod is inserted through the top of the top cover and the bottom of the electromagnetic conveying tube, the spiral conveying assembly is located in the electromagnetic conveying tube and at the bottom of the electromagnetic conveying tube, and the dispersion blades are attached to the top of the electromagnetic conveying tube;

[0016] By rotating the motor, the spiral conveying assembly and the dispersing blades can be driven to rotate, so that the powder falling to the bottom center of the mixing tank enters the electromagnetic conveying tube under the drive of the spiral conveying assembly and moves up along the electromagnetic conveying tube. When the powder reaches the top of the electromagnetic conveying tube, the powder is broken up by the rotation of the dispersing blades, so that various powders escape into the top space of the mixing tank, the powders are fully mixed, and fall again to the space outside the electromagnetic conveying tube in the mixing tank under the action of gravity. The mixing efficiency is high, and there is basically no collision and friction when the powder is transported and when the powder is between the electromagnetic conveying tube and the mixing tank, thereby avoiding the heating of the powder and ensuring the quality of the powder.

[0017] The utility model has the following beneficial effects:

[0018] The utility model solves the problem that powder mixing equipment usually stirs and mixes multiple powders by a stirring rod or a stirring blade, but since the multiple powders are mostly poured into the tank body in sequence, upper and lower stratification occurs between the multiple powders, and the stirring blade usually stirs in the horizontal direction, making it difficult to quickly and evenly stir a large amount of powders. The space in the mixing tank can be divided by multiple partition plates to avoid stratification of the multiple powders in the vertical direction. When the powders are mixed, the multiple powders fall to the bottom of the mixing tank under the action of gravity and are conveyed to the electromagnetic conveying pipe through a high-speed rotating spiral conveying component. When the powders reach the top of the electromagnetic conveying pipe, they are mixed by breaking up to make the powders fully mixed, and fall again to the space outside the electromagnetic conveying pipe in the mixing tank under the action of gravity, so that the powders are circulated and processed, and the mixing efficiency is high.

[0019] The utility model solves the problem that a certain amount of air is often mixed into the powder material when it is poured into the mixing equipment, and a certain amount of moisture may exist in the air. When the powder material collides with the stirring blade during stirring, the temperature in the equipment is often increased. At this time, the powder material may react when in contact with the hot and humid air, thereby reducing the quality of the finished product by arranging the mixing tank and the top cover. Before the powder material is mixed, the mixing tank is evacuated by a high-pressure pump to make the mixing tank in a relative vacuum, which can prevent the powder material from contacting with moisture in the air when it is broken up. Moreover, the powder material is located between the electromagnetic conveying pipe and the mixing tank in the mixing pipe most of the time, and basically no collision and friction will occur, thereby avoiding the heating of the powder material and ensuring the quality of the powder material.

After the powders move to the top of the electromagnetic conveying pipe 102, the mixed powders are broken up by the high-speed rotating dispersion blades 205, so that a small amount of powders quickly escape in a relatively open space, so that the powders are fully mixed and fall again to the space outside the electromagnetic conveying pipe 102 in the mixing tank 1 under the action of gravity.

[0029] Among them Figure 1-3 As shown, one end of each partition plate 103 is clamped and fixed with an adsorption plate 105, the adsorption plate 105 is attached to the outer peripheral surface of the electromagnetic delivery pipe 102, the other end of the partition plate 103 relative to the adsorption plate 105 is attached to the inner wall of the mixing tank 1, the top of the outer peripheral surface of the mixing tank 1 is penetrated and welded with a high-pressure pump 101, the top of the outer peripheral surface of the high-pressure pump 101 is penetrated and welded with an exhaust pipe 106, the center of the bottom of the mixing tank 1 is penetrated and welded with a discharge pipe 104, and the electromagnetic delivery pipe 102 is suspended from the top of the discharge pipe 104;

[0030] According to the type of powder, multiple partition plates 103 are taken, and the electromagnetic conveying tube 102 is energized to make the adsorption plate 105 fit the outer peripheral surface of the electromagnetic conveying tube 102. According to the proportion of the various powders, the position of the partition plate 103 is adjusted to divide the space in the mixing tank 1. After all the powders are poured into the inside of the mixing tank 1, the mixing tank 1 is evacuated by the high-pressure pump 101 to make the mixing tank 1 in a relative vacuum to prevent the powder from contacting with moisture in the air when it is broken up. After the powder is mixed, the discharge pipe 104 is opened to pour out the powder.

Under the action of gravity, the powder enters the appropriate separation space in the mixing tank 1 through the feed pipe 203. When mixing the powder, the rotating motor 201 drives the rotating rod 202 to rotate, and further drives the spiral conveying component 204 and the dispersing blades 205 to rotate, so that the powder falling to the bottom center of the mixing tank 1 enters the electromagnetic conveying driven by the spiral conveying component 204. The powders are placed in the electromagnetic conveying tube 102 and move upward along the electromagnetic conveying tube 102. When the powders continuously reach the top of the electromagnetic conveying tube 102, the powders are broken up by the rotation of the dispersing blades 205, so that various powders escape into the top space in the mixing tank 1, and the powders are fully mixed. Then, the powders fall into the space outside the electromagnetic conveying tube 102 in the mixing tank 1 again under the action of gravity. In addition, when the powders are conveyed and located between the electromagnetic conveying tube 102 and the mixing tank 1, basically no collision or friction occurs, thereby avoiding the heating of the powders.

After the various powders are fed, the feed pipe 203 is closed and the high-pressure pump 101 is controlled to evacuate the mixing tank 1, so that the mixing tank 1 is in a relative vacuum to prevent the powder from being mixed with the air when it is dispersed. The powder material is brought into contact with the moisture of the mixing tank 1, and the rotating motor 201 is controlled to drive the rotating rod 202 to rotate, and further drives the spiral conveying assembly 204 and the dispersing blades 205 to rotate, so that the powder material falling to the bottom center of the mixing tank 1 enters the electromagnetic conveying tube 102 driven by the spiral conveying assembly 204, and moves up along the electromagnetic conveying tube 102. When the powder material continuously reaches the top of the electromagnetic conveying tube 102, the powder material is broken up by the rotation of the dispersing blades 205, so that various powder materials escape into the top space of the mixing tank 1, so that the powder materials are fully mixed, and fall into the space outside the electromagnetic conveying tube 102 in the mixing tank 1 again under the action of gravity, and move to the bottom of the mixing tank 1 again with the transportation of the powder material for transportation and breaking up.
