Description

Technical Field

[0001] This utility model relates to the field of mixing tank technology, and more specifically, to a magnetically formed mixing tank. Background Technology

[0002] In the production of magnetic materials, it is usually necessary to transport the magnetic material slurry from the mixing tank to the molding die or other production equipment. The slurry required for pressing the magnetic molding blank is ball-milled and then flows into the molding die. Before pressing, the slurry is stored in the mixing tank and mixed evenly with water in a certain proportion according to the molding process requirements. After being mixed evenly, the material is injected into the molding die through an injection pump for pressing. In order to enable the slurry to enter the pump quickly, the mixing tank is a structure with a set of spiral blades and a cone.

[0003] For example, Chinese Patent Publication No. CN219404788U, published on July 25, 2023, discloses a mixing device with a conical discharge port at the bottom to facilitate the flow of mud from the discharge pipe. However, during mixing, the slurry at the bottom is transported to the molding die by the pressure generated by mechanical mixing and the suction of the injection pump. A vortex dead zone easily forms at the conical bottom of the mixing tank, resulting in a hollow area at the center of the conical discharge port, preventing the removal of hard material around the discharge port. Therefore, traditional mixing devices often have a large amount of residual material at the bottom of the mixing tank, leading to hard material in the molded product, causing slurry waste and environmental pollution. Utility Model Content

[0004] This invention overcomes the shortcomings of existing mixing tanks where the bottom of the conical tank tends to become hollow during mixing, leading to hard material buildup around the conical discharge port and wasted slurry. It provides a magnetic forming mixing tank that effectively avoids hollowing of the mud at the conical position by changing the conical structure of the discharge port to an inclined structure. This prevents hard material buildup around the discharge port, reduces slurry waste, and improves the forming effect of the finished product.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a magnetically formed stirring tank, comprising:

[0006] The barrel has a stirring motor on top, the output shaft of which is connected to a stirring shaft, and a stirring paddle is mounted on the stirring shaft.

[0007] The extrusion barrel has an inclined bottom plate at its bottom, and a discharge port is provided on the side wall of the extrusion barrel at a position corresponding to the lower end of the inclined bottom plate.

[0008] The spiral blades extend from the bottom of the stirring shaft into the extrusion barrel, and the spiral blades are located on the part of the stirring shaft that is in the extrusion barrel.

[0009] In this invention, the rotating stirring shaft causes the spiral blades to rotate as well. These blades push the material towards the bottom outlet within the extrusion barrel, thereby increasing the discharge speed of the slurry. Furthermore, by designing the bottom of the extrusion barrel with an inclined shape, the slurry becomes hollow at the conical position, preventing hard material residue around the outlet. This shortens the injection time, increases the injection force, and improves the molding effect. It also eliminates the generation of hard material in the blank molding process, significantly increasing the product yield.

[0010] Preferably, a motor mounting plate is provided on the top of the barrel, the stirring motor is mounted on the motor mounting plate, and the top of the barrel forms feeding ports on both sides of the motor mounting plate.

[0011] The motor mounting plate in this application has four edges, including two parallel straight edges and opposing curved edges. The curved edges are adapted to the top edge line of the barrel. The straight edges form a feeding port with the edge of the barrel, and each straight edge forms a feeding port with the edge of the barrel. This application has two feeding ports to facilitate feeding materials into the barrel.

[0012] Preferably, the agitator is a spiral agitator.

[0013] While agitating the slurry, the spiral agitator can also push the slurry towards the extrusion tank, thereby increasing the pressure of the slurry flowing out of the outlet and thus shortening the injection molding time.

[0014] Preferably, an inclined base plate is provided at the bottom of the extrusion barrel; the upper end of the inclined base plate is hinged to the side wall of the extrusion barrel; a fixed arc plate is provided at the lower end of the inclined base plate, and an extended arc plate that cooperates with the fixed arc plate is provided at the bottom of the extrusion barrel; the extended arc plate and the fixed arc plate are tightly fitted together by bolts.

[0015] The inclined base plate is designed to be hinged to the extrusion tank, so that when the tank body and extrusion tank need to be cleaned, the bolts can be removed, allowing the inclined base plate to rotate around the side wall of the extrusion tank, opening the bottom of the extrusion tank, and allowing the slurry to flow out from the bottom of the extrusion tank more quickly.

[0016] Preferably, a sealing ring is provided on the edge of the inclined base plate facing the extrusion barrel. When the inclined base plate is fitted with the bottom of the extrusion barrel, the sealing ring fits tightly between the extrusion base plate and the bottom edge of the extrusion barrel.

[0017] The sealing ring improves the sealing performance between the inclined base plate and the bottom of the extrusion tank, preventing slurry from leaking out from the bottom of the extrusion tank when the inclined base plate is closed.

[0018] Preferably, the diameter of the spiral blades is matched with the diameter of the extrusion barrel.

[0019] It can better match the extrusion tank and further increase the pressure of the slurry discharge.

[0020] Preferably, a telescopic rod is provided at the end of the stirring shaft near the extrusion barrel, and a connector is hinged at the end of the telescopic rod away from the stirring shaft, with several arc-shaped stirring paddles provided on the connector.

[0021] The arc-shaped stirring paddle, pushed by the abutment spring, contacts the inclined bottom plate. Driven by the stirring shaft, the arc-shaped stirring paddle rotates against the upper surface of the inclined bottom plate. This not only stirs the slurry at the bottom of the extrusion tank, but also increases the discharge speed of the slurry due to the action of the arc-shaped stirring paddle.

[0022] Preferably, the stirring shaft has a telescopic hole at the end near the extrusion barrel, and the telescopic rod is slidably disposed in the telescopic hole; an abutment spring is provided between the end of the telescopic rod and the telescopic hole, and the abutment spring pushes the telescopic rod to move outward.

[0023] The arc-shaped stirring paddle, pushed by the abutment spring, contacts the inclined bottom plate. Driven by the stirring shaft, the arc-shaped stirring paddle rotates against the upper surface of the inclined bottom plate. This not only stirs the slurry at the bottom of the extrusion tank, but also increases the discharge speed of the slurry due to the action of the arc-shaped stirring paddle.

[0024] Compared with existing technologies, the beneficial effects of this invention are as follows: With the rotation of the stirring shaft, the spiral blades also rotate, pushing the blades towards the bottom outlet within the extrusion barrel, thereby increasing the discharge speed of the slurry. Furthermore, by setting the bottom of the extrusion barrel to an inclined shape, the hollowing out of the slurry at the cone position is achieved, preventing hard material residue around the outlet, shortening the injection time, increasing the injection force, improving the molding effect, eliminating the generation of hard material in the blank molding, and significantly increasing the product yield.

[0037] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0038] Example 1: Refer to Figure 1 and Figure 2 As shown, a magnetically formed mixing tank includes: a tank body 1 and an extrusion tank 2.

[0039] The barrel body 1 is cylindrical in shape. A stirring motor 3 is installed at the top of the barrel body 1. A stirring shaft 4, which is connected to the output shaft of the stirring motor 3, is installed on the axis of the barrel body 1. A stirring paddle 41 is installed on the stirring shaft 4. The output shaft of the stirring motor 3 and the stirring shaft 4 are connected by a coupling 31.

[0040] The outer wall of the extrusion barrel 2 is cylindrical, and the diameter of the extrusion barrel 2 is smaller than the diameter of the barrel body 1. An inclined bottom plate 7 is inclinedly arranged at the bottom of the extrusion barrel 2. A discharge port 21 is provided on the side wall of the extrusion barrel 2, corresponding to the lower end of the inclined bottom plate 7. The higher end of the inclined bottom plate 7 is the top, and the lower end is the bottom. The discharge port 21 is located at the bottom end of the inclined bottom plate 7, allowing the slurry to be discharged more fully from the discharge port 21.

[0041] The bottom of the helical blade 5 and the stirring shaft 4 extend into the extrusion barrel 2. The helical blade 5 is located in the part of the stirring shaft 4 located in the extrusion barrel 2.

[0042] As the stirring shaft 4 rotates, the spiral blades 5 also rotate. The spiral blades 5 are pushed towards the discharge port 21 at the bottom of the extrusion tank 2, thereby increasing the discharge speed of the slurry.

[0043] In this invention, by setting the bottom of the extrusion barrel 2 to an inclined shape, the problem of hollowing out the material at the cone position is solved, and no hard material remains around the discharge port 21. The injection time can be shortened, the injection force can be increased, the molding effect is better, the generation of hard material in the blank molding is eliminated, and the product yield is greatly improved.

[0044] A motor mounting plate 6 is provided on the top of the barrel 1, and the stirring motor 3 is mounted on the motor mounting plate 6. Feeding ports are formed on both sides of the top of the barrel 1 on the motor mounting plate 6. The motor mounting plate 6 in this application has four edges, including two parallel straight edges and opposing curved edges. The curved edges are adapted to the top edge line of the barrel 1. The straight edges form feeding ports with the edge of the barrel 1, with each straight edge forming one feeding port. This application provides two feeding ports for convenient feeding of materials into the barrel 1.

[0045] Limiting flanges 61 are provided on the edge of the arc-shaped side. When the motor mounting plate 6 is installed on the barrel 1, the limiting flanges 61 on both sides of the arc-shaped side can play a limiting role on both sides of the barrel 1.

[0046] In one embodiment, the stirring paddle 41 is a spiral stirring paddle 41. While stirring the slurry, the spiral stirring paddle 41 can also push the slurry towards the extrusion tank 2, thereby increasing the pressure of the slurry flowing out of the outlet 21 and thus shortening the injection molding time.

[0047] In one embodiment, the diameter of the spiral blade 5 is adapted to the diameter of the extrusion barrel 2. This allows for a better fit with the extrusion barrel 2, further increasing the pressure of the slurry discharge.

[0048] In this invention, the spiral blades 5 rotate under the rotation of the stirring shaft 4. The spiral blades 5 are pushed towards the discharge port 21 at the bottom inside the extrusion barrel 2, thereby increasing the discharge speed of the slurry. By setting the bottom of the extrusion barrel 2 to an inclined shape, the slurry is made hollow at the cone position, preventing hard material from remaining around the discharge port 21. This shortens the injection time, increases the injection force, and improves the molding effect. It also eliminates the generation of hard material in the blank molding process, significantly improving the product yield.

[0052] The bottom of the helical blade 5 and the stirring shaft 4 extend into the extrusion barrel 2. The helical blade 5 is located in the part of the stirring shaft 4 located in the extrusion barrel 2.

[0053] As the stirring shaft 4 rotates, the spiral blades 5 also rotate. The spiral blades 5 are pushed towards the discharge port 21 at the bottom of the extrusion tank 2, thereby increasing the discharge speed of the slurry.

[0054] In this invention, by setting the bottom of the extrusion barrel 2 to an inclined shape, the problem of hollowing out the material at the cone position is solved, and no hard material remains around the discharge port 21. The injection time can be shortened, the injection force can be increased, the molding effect is better, the generation of hard material in the blank molding is eliminated, and the product yield is greatly improved.
