Description

Technical Field

[0001] This utility model relates to the field of graded mixing device technology, specifically a fine graded mixing device. Background Technology

[0002] A fine-grained mixing device is an industrial equipment used to efficiently, uniformly, and controllably mix and separate two or more materials.

[0003] Existing fine-grading mixing devices typically use a dispersing disc for centrifugal separation when separating and mixing particulate materials. Coarse materials are thrown against the inner wall of the dispersing chamber by centrifugal force, while fine materials aggregate in the middle of the chamber and are discharged from the top pipe with gas. Coarse materials are discharged from the bottom pipe under gravity. However, the dispersing disc is usually cooled by a jacket, which is slow and does not facilitate the collection of fine materials, resulting in poor performance. Furthermore, air needs to be supplied to the dispersing chamber during grading and mixing, but this does not eliminate static electricity in the materials, causing them to easily clump together due to static electricity, resulting in poor dispersion.

[0004] Therefore, a refined graded mixing device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a fine-grained mixing device that can solve the problem of materials easily agglomerating into clumps under the influence of static electricity during the dispersion process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fine-grained grading mixing device, comprising a tank, a top cover installed on the top of the tank, a hollow shaft coaxially rotatably connected to the bottom of the top cover, a dispersing disc installed at the bottom of the hollow shaft, a cooling chamber opened inside the dispersing disc, the cooling chamber communicating with the bottom end of the hollow shaft, and a plurality of exhaust holes opened on the edge of the dispersing disc, the exhaust holes communicating with the interior of the cooling chamber;

[0007] A housing is installed on the top of the top cover, and the top of the hollow shaft passes through the top cover and the housing. A gas supply pipe is connected to the top of the hollow shaft through a rotary joint, and the other end of the gas supply pipe is connected to a gas source.

[0008] An air inlet is provided on one side of the bottom of the tank. An air inlet pipe is provided at one end of the air inlet. A connecting pipe is provided between the air inlet pipe and the air inlet. The adjacent ends of the air inlet pipe and the air inlet are connected to the connecting pipe through flanges.

[0009] A fixing base is installed at the top of the connecting tube, and several ion rods are installed at the bottom of the fixing base, with the end of each ion rod extending into the interior of the connecting tube.

[0010] Preferably, the vent is oriented tangentially to the dispersion disc.

[0011] Preferably, a connecting plate is installed at the bottom of the dispersing plate, and several blades are installed on the edge of the connecting plate. One end of each blade extends out from below the dispersing plate, and each blade is inclined.

[0012] Preferably, a conveying pipe is installed on one side of the top of the tank, and the bottom end of the conveying pipe passes through the top cover and extends above the dispersing disc.

[0013] Preferably, the bottom edge of the tank is equipped with several support legs.

[0014] Preferably, a second discharge pipe is installed at the bottom of the tank, and a discharge valve is installed on the second discharge pipe;

[0015] A first discharge pipe is installed on one side of the top of the tank, and the first discharge pipe is tangential to the side of the tank.

[0016] Preferably, the first discharge pipe is located above the dispersing disc.

[0017] Preferably, a first gear is coaxially mounted on the top side of the hollow shaft, a drive motor is mounted on the top of the housing, a second gear is mounted on the output shaft end of the drive motor, the second gear is located inside the housing, and the second gear meshes with the first gear.

[0018] Compared with the prior art, the present invention provides a fine-grained graded mixing device, which has the following beneficial effects:

[0019] 1. By opening a cooling chamber inside the dispersion disc and supplying external cooling air to the cooling chamber through a hollow shaft via an air supply pipe, the dispersion disc is cooled. After cooling, the air is discharged through the exhaust port, and the blades agitate the gas towards the top of the tank. This allows the dispersed fine material to be blown towards the top of the tank while cooling, thus improving the performance.

[0020] 2. By installing a connecting pipe between the air inlet pipe and the air outlet, and installing an ion bar inside the connecting pipe, the gas flowing through the connecting pipe can be ionized by the ion bar. When the ionized gas flows into the tank, it can remove static electricity from the material, preventing the material from agglomerating due to static electricity during the dispersion process, thus improving the dispersion effect.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example:

[0030] Please see Figure 1 - Figure 6This embodiment of a fine-grading mixing device includes a tank 1, with several legs 9 installed on the bottom edge of the tank 1, a top cover 2 installed on the top of the tank 1, and a hollow shaft 15 rotatably connected to the bottom of the top cover 2. A dispersing disc 14 is installed at the bottom of the hollow shaft 15, and a cooling chamber 21 is opened inside the dispersing disc 14. The cooling chamber 21 is connected to the bottom end of the hollow shaft 15. Several exhaust holes 12 are opened on the edge of the dispersing disc 14, and the exhaust holes 12 are connected to the inside of the cooling chamber 21. A box 6 is installed on the top of the top cover 2, and the top of the hollow shaft 15 passes through the top cover 2 and the box 6. The top of the hollow shaft 15 is connected to a gas supply pipe 4 through a rotary joint 16. The other end of the gas supply pipe 4 is connected to a gas source. In actual use, the cooling gas can be transported to the hollow shaft 15 through the gas supply pipe 4 via the gas source, and then the cooling gas is transported to the cooling chamber 21 to cool down the dispersing disc 14. After that, the air is discharged through the exhaust holes 12.

[0031] It should be noted that, as Figure 2 and Figure 4 As shown, a first gear 22 is coaxially mounted on the top side of the hollow shaft 15, and a drive motor 3 is mounted on the top of the housing 6. A second gear 23 is mounted on the output shaft end of the drive motor 3. The second gear 23 is located inside the housing 6 and meshes with the first gear 22. In actual use, the drive motor 3 can drive the second gear 23 to rotate, which in turn drives the first gear 22 to rotate, thereby driving the hollow shaft 15 to rotate. In this way, the high-speed rotation of the dispersing disc 14 can be controlled during use.

[0032] It should be noted that, as Figure 3 As shown, the exhaust port 12 is oriented towards the tangent of the dispersion plate 14, so that when the dispersion plate 14 rotates at high speed, the air in the cooling chamber 21 can be thrown out through the exhaust port 12 under the action of centrifugal force.

[0033] like Figure 3 and Figure 5 As shown, a connecting plate 17 is installed at the bottom of the dispersing plate 14. Several blades 13 are installed on the edge of the connecting plate 17. One end of each blade 13 extends out from below the dispersing plate 14, and each blade 13 is set at an angle. The blades 13 will rotate with the dispersing plate 14. When the blades 13 rotate, they will drive the air to flow towards the top of the tank 1, which can provide lift for the discharge of fine materials, making the discharge of fine materials smoother.

[0034] like Figure 1 and Figure 4As shown, a conveying pipe 5 is installed on one side of the top of the tank 1. The bottom end of the conveying pipe 5 passes through the top cover 2 and extends to the top of the dispersing disc 14. In actual use, the staff can convey external materials to the dispersing disc 14 through the conveying pipe 5. The materials are dispersed by the high-speed rotation of the dispersing disc 14 and thrown onto the side wall of the tank 1 under the action of centrifugal force.

[0035] like Figure 1 and Figure 4 As shown, an air inlet 25 is provided on one side of the bottom of the tank 1. An air inlet pipe 7 is provided at one end of the air inlet 25. A connecting pipe 18 is provided between the air inlet pipe 7 and the air inlet 25. The adjacent ends of the air inlet pipe 7 and the air inlet 25 are connected to the connecting pipe 18 through the flange 19. The air inlet 25 is tangential to the side wall of the tank 1. In actual use, external air can be blown into the tank 1 through the air inlet pipe 7, the connecting pipe 18 and the air inlet 25, so that the air can be arranged in a spiral along the inner wall of the tank 1. After the gas is delivered into the tank 1, the air pressure at the bottom of the tank 1 will be greater than the air pressure at the top. In this way, the airflow can carry the fine material to the bottom of the tank 1.

[0036] like Figure 1 and Figure 6 As shown, a fixing seat 20 is installed at the top of the connecting pipe 18, and several ion rods 24 are installed at the bottom of the fixing seat 20. The end of each ion rod 24 extends into the connecting pipe 18. Under the action of the ion rods 24, the air passing through the connecting pipe 18 can be ionized, so that the air contains a large number of negative ions. In this way, when the air is delivered into the tank 1, it can remove the static electricity in the material, prevent the material from agglomerating, and improve the use effect.

[0037] like Figure 2 As shown, a first discharge pipe 8 is installed on one side of the top of the tank body 1. The first discharge pipe 8 is tangential to the side of the tank body 1 and is located above the dispersion plate 14. Fine materials carried by the gas can be discharged through the first discharge pipe 8.

[0038] like Figure 1 and Figure 4 As shown, a second discharge pipe 10 is installed at the bottom of the tank body 1, and a discharge valve 11 is installed on the second discharge pipe 10. Coarse material in the material can be thrown towards the inner wall of the tank body 1 under the action of centrifugal force, and will move downward along the inner wall of the tank body 1 under the action of gravity, and finally be discharged from the second discharge pipe 10 through the discharge valve 11.

[0039] The working principle of the above embodiments is as follows:

[0040] In use, the operator drives the second gear 23 to rotate through the drive motor 3. The second gear 23 drives the hollow shaft 15 to rotate through the first gear 22, which controls the high-speed rotation of the dispersing disc 14. At this time, the operator transports the material to the top of the dispersing disc 14 through the conveying pipe 5. Under the centrifugal force generated by the high-speed rotation of the dispersing disc 14, the coarse material in the material can be thrown towards the inner wall of the tank 1 and move downward along the inner wall under the action of gravity, while the fine material in the material can rotate with the airflow in the tank 1.

[0041] At this time, the staff delivers external gas into the tank 1 through the air inlet pipe 7, connecting pipe 18 and air inlet 25. When the air flows through the connecting pipe 18, the air can be ionized by the ion rod 24, so that a large number of negative ions are generated in the air. In this way, when the gas is delivered into the tank 1, it can remove the static electricity in the material, avoid the material from agglomerating during the grading process, and improve the use effect.

[0042] During the grading process, the staff can deliver external cooling gas to the hollow shaft 15 through the gas supply pipe 4. The cooling gas flows into the cooling chamber 21 along the hollow shaft 15 and is thrown out from the exhaust port 12 under the action of centrifugal force. During the process of being thrown out, the cooling gas will cool down the dispersion plate 14, so that the dispersion plate 14 is kept at the preset temperature and the use effect is improved.

[0043] The gas discharged from the exhaust port 12 can flow upward under the action of the blade 13, and together with the gas delivered to the tank 1 by the intake pipe 7, it will discharge the fine material from the first discharge pipe 8, while the coarse material will fall into the bottom of the tank 1 under the action of gravity, and pass through the discharge valve 11 to be discharged from the second discharge pipe 10, thus completing the graded mixing.

[0044] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
