[0002] The existing patent number is 202321742334.7, and the name is a utility model patent for a powerful mixer, which uses the method of swinging the barrel left and right. On the one hand, it can make the movement of the material diverse. While the material is subjected to the force generated by the rotation of the stirring blade, it is also subjected to the force generated by the swinging of the barrel left and right. On the other hand, in order to ensure that when the barrel cover is flipped to one side and opened, the stirring shaft and the stirring blade do not interfere with the inner wall of the other side of the barrel cover, the stirring mechanism is set on the side away from the opening of the barrel cover. It is also possible to throw the material in the barrel to the outer edge to contact the stirring blade, thereby improving the stirring and crushing efficiency of the material. In actual use, a good mixing effect has been achieved.

[0003] The barrel in this patent is a double-layer barrel. The lower part of the inner barrel (referring to the inner pot body) is in the form of a flange. During the installation process, it is connected to the transmission main shaft at the lower part of the outer barrel (referring to the outer pot body) through multiple bolts. Generally, at least 6-8 bolts are required to meet the connection strength requirements. When the barrel needs to be inspected, multiple bolts need to be screwed to achieve disassembly, which takes a long time and also brings inconvenience to the installation of the barrel.

[0004] In summary, the connection between the inner barrel and the transmission main shaft of the existing mixer has the problem of being inconvenient to disassemble. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the connection between the inner barrel and the transmission main shaft of the existing mixer is inconvenient to disassemble, and further provide a powerful mixer pot body that can be quickly disassembled.

[0007] Preferably, the semi-arc plate has handles on both sides.

[0008] Preferably, the semi-arc plate is a U-shaped plate.

[0009] Furthermore, the radius of the other end of the elongated hole is greater than the maximum outer diameter of the tension pin.

[0010] Preferably, a rectangular groove is processed on the lower portion of the tension pin.

[0011] Preferably, the outer diameter of the rectangular groove is transitionally matched with the middle portion of the elongated hole.

[0016] Compared with the prior art, the utility model has the following effects:

[0017] 1. The utility model can realize the rapid disassembly and assembly of the inner pot body, and the specific implementation method is:

[0018] Since the bottom end surface of the cooling shell 15 at the lower part of the inner pot body of the utility model is the flange 7, the initial positioning of the inner pot body during installation is performed through the pipe joint 17 on the inner pot body drive unit 16, and then the pressure plate 4 is pressed onto the flange 7. At this time, the tensioning pin 5 on the transmission shaft cover 6 on the transmission main shaft 2 passes through the long strip hole on the pressure plate 4, and the pressure plate is rotated clockwise to achieve a quick connection between the inner pot body and the transmission main shaft.

[0019] 2. The utility model adopts two methods to achieve sealing. These two sealing methods can be used separately or simultaneously according to the specific conditions of the mixed materials. The first sealing method is that the utility model is provided with a downward inclined surface at the inner edge of the upper end surface of the inner pot body. The inclined surface can not only achieve close contact with the VD sealing ring, but also facilitate the automatic falling of the powder when the powder falls on the inclined surface. The second sealing method is that the utility model uses a respirator to draw negative pressure into the inner pot body. Under the action of negative pressure, the pressure inside the inner pot body is lower than the external atmospheric pressure. Therefore, the sealing ring can fit more closely with the inclined surface, ensuring the sealing effect and making the sealing more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solution of the present utility model is not limited to the specific implementation modes listed below, but also includes any reasonable combination of the specific implementation modes.

[0022] Specific implementation method 1: Combination Figures 1 to 4 The present embodiment is described. The present embodiment comprises an outer barrel 1 and a transmission main shaft 2. The upper rotating seal of the transmission main shaft 2 passes through the bottom of the outer barrel 1 and extends upward. The inner barrel 3, a pressure plate 4 and a tensioning pin 5 are also included. The pressure plate 4 is a semi-arc plate, and long strip holes 8 are symmetrically provided on the semi-arc plate, and the radius of one end of the long strip hole 8 is smaller than the radius of the other end; the lower part of the inner barrel 3 is a flange 7, the inner barrel 3 is coaxially embedded in the outer barrel 1, and the inner barrel 3 is arranged on the transmission main shaft 2, the tensioning pin 5 passes through the through hole on the flange 7 and is screwed on the transmission shaft cover 6, the long strip hole 8 on the pressure plate 4 passes through the tensioning pin 5, and then the pressure plate 4 is rotated and pressed on the flange 7.

[0023] In this embodiment, the flange 7 and the transmission shaft cover 6 of the transmission main shaft 2 are quickly connected by a pressure plate, without the need to screw the bolts one by one. At the same time, it is also very convenient to disassemble by rotating the pressure plate.

[0024] Specific implementation method 2: Combination Figure 2 To explain this embodiment, the semi-arc plate of this embodiment has handles 9 on both sides. This arrangement makes it easy to rotate the pressing plate, and the entire operation is simple and labor-saving. Other components and connection relationships are the same as those of the first embodiment.

[0025] Specific implementation method three: Combination Figure 2 To explain this embodiment, the semi-arc plate of this embodiment is a U-shaped plate. Such a configuration can play a role in press-fitting between the flange 7 and the transmission shaft cover 6, and the connection area is large, making the connection between the two more secure. Other components and connection relationships are the same as those of the specific embodiment one or two.

[0026] Specific implementation method four: Combination Figure 2To explain this embodiment, the radius of the other end of the elongated hole 8 of this embodiment is larger than the maximum outer diameter of the tension pin 5. With this arrangement, the end of the elongated hole with a larger outer diameter is convenient for inserting the tension pin 5. When the pressure plate is downward and in contact with the transmission shaft cover 6, when the handle 9 is rotated by both hands, the elongated hole contacts the rectangular groove 10, and the elongated hole is clamped on the rectangular groove 10 to fix the pressure plate. The other components and connection relationships are the same as any one of the specific embodiments 1 to 3.

[0027] Specific implementation method five: Combination Figure 3 To explain this embodiment, the lower part of the tension pin 5 of this embodiment is processed with a rectangular groove 10. In this way, the rectangular groove 10 has a limiting effect on the upper and lower end surfaces of the pressing plate, ensuring the connection between the pressing plate and the transmission main shaft 2. The other components and connection relationships are the same as any one of the specific embodiments 1 to 4.

[0028] Specific implementation method six: Combination Figure 2 To explain this embodiment, the outer diameter of the rectangular groove 10 of this embodiment is transitionally matched with the middle part of the long strip hole 8. This arrangement facilitates the pressure plate and the tension pin 5 to ensure that they can achieve relative rotation without too much gap, thereby avoiding the problem of shaking of the inner pot body when rotating at high speed. The other components and connection relationships are the same as any one of the specific embodiments 1 to 5.

[0029] Specific implementation method seven: Combination Figure 1 To explain this embodiment, the inner wall upper end surface of the inner barrel 3 of this embodiment is provided with an inwardly inclined inclined surface 11. With such a configuration, when the sealing ring deforms outward, it can fit more firmly with the inclined surface of the inner pot body, and can also make the powder slide downward. The other components and connection relationships are the same as any one of the specific embodiments 1 to 6.

[0030] Specific implementation method eight: Combination Figure 1 To explain this embodiment, the angle of the inclined surface 11 of this embodiment is 40°-50°. Such a setting is not only convenient for processing, but also can ensure that the powder slides smoothly, and also provides a sufficient sealing angle for the deformation of the sealing ring. The other components and connection relationships are the same as any one of the specific embodiments 1 to 7.

[0031] The angle of the inclined surface 11 in this embodiment is preferably 45°.

[0032] Specific implementation method nine: Combination Figure 1This embodiment is described. This embodiment also includes an upper cover 12 and a VD sealing ring 13. The VD sealing ring 13 is installed on the lower end surface of the upper cover 12. The upper cover 12 can be opened and installed on the outer barrel 1 and the inner barrel 3. The VD sealing ring 13 is against the inclined surface 11 on the inner barrel 3. With such a configuration, the sealing ring has a certain flexibility when actually used. Therefore, in the initial state, the sealing ring contacts the inclined surface and can play a sealing role. When the pressure in the pot body is too high, the inner pot body is vacuumed through the respirator. At this time, the sealing ring will fit more closely with the inclined surface under the action of negative pressure, and the sealing effect is better. Other components and connection relationships are the same as any one of the specific embodiments one to eight.

[0033] Specific implementation method ten: Combination Figure 1 This embodiment further includes a respirator 14, which is mounted on the upper cover 12 and communicates with the inner barrel 3. This arrangement facilitates the vacuuming of the inner pot body when the pressure of the inner pot body is too high, thereby ensuring a closer contact between the sealing ring and the inclined surface, and effectively ensuring the sealing effect. The other components and connection relationships are the same as any one of the specific embodiments 1 to 9.

[0034] Combination Figures 1 to 4 As shown, the working principle of the utility model is described:

[0035] When the utility model is actually used, it is used for Figure 4 The intensive mixer is shown in FIG. The intensive mixer can pitch and swing the entire pot body, and when discharging materials, the inner pot body is driven by the inner pot body driving unit 16 to rotate, and the rotation of the inner pot body can improve the efficiency of discharging materials.

[0036] A cavity for cooling the inner pot body is reserved between the inner pot body and the outer pot body, and the cavity is connected to the transmission main shaft 2. Since the transmission main shaft 2 is a hollow transmission main shaft, a pipe joint 17 is provided inside it, and the lower part of the pipe joint 17 is connected to a water pipe. Water is circulated in and out of the cavity through an external cooling system, thereby realizing cooling of the inner pot body.

[0037] In terms of quick disassembly, the utility model firstly rotates the transmission main shaft 2 through the bearing to be installed in the middle of the bottom end of the outer barrel 1, and the transmission main shaft 2 is sealed and connected with the outer barrel 1. Then the inner barrel 3 is coaxially placed on the transmission shaft cover 6 at the upper end of the transmission main shaft 2, the tension pin 5 passes through the through hole on the flange 7 and is screwed on the transmission shaft cover 6, the long strip hole 8 on the pressing plate 4 passes through the tension pin 5, and then the pressing plate 4 is rotated and pressed on the flange 7, so that the long strip hole on the pressing plate is stuck on the rectangular groove 10, so as to realize the quick disassembly and assembly between the inner pot body and the transmission main shaft 2.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
