The plug 200 is arranged in the shell 100, and the plug 200 can extend out of the shell 100 from the opening. After the plug 200 extends out of the shell 100, the plug 200 is connected with a discharge port of a mixing device, and is used for plugging the discharge port. The plug 200 can also extend into the shell 100 from the opening. After the plug 200 extends into the shell 100, the opening is in communication with the discharge port of the mixing device, so that the mixed material can be discharged from the mixing device to the discharging assembly.

[0048] The driving mechanism is arranged outside the shell 100, and the driving mechanism is arranged on the second side wall 101. The driving mechanism comprises a first driving shaft 3011 and a second driving shaft 3021. The first driving shaft 3011 and the second driving shaft 3021 both extend into the shell 100 from the second side wall 101, and are connected with the plug 200.

[0064] That is, during the discharging process or after the discharging process is completed, the plug 200 extends into the shell 100 from the opening and close to the second side wall 101, and the third air inlet valve 603 is opened, and gas enters the shell 100 from the third air inlet valve 603 to clean the material that may be left on the plug 200 and in the shell 100, so as to avoid the material left.

[0065] The third air inlet valve 603 is arranged on the cover plate 102 of the shell 100, and the third air inlet valve 603 is in communication with the four air inlets.

[0066] In the embodiment of the application, the plug 200 is made of a non-metal material, and the non-metal plug can avoid metal pollution caused by metal debris to the material, and the non-metal plug has a relatively light weight, so that the load required by the cylinder is low.

[0067] The non-metal material can include high-molecular-weight monomer casting nylon, ultra-high molecular weight polyethylene, polyformaldehyde, polytetrafluoroethylene or polyether ether ketone.

[0068] The high-molecular-weight monomer casting nylon (MC nylon) is a material directly polymerized by lactam monomers under the action of strong alkali (such as sodium hydroxide) and some catalysts by using a mold, and the MC nylon has the characteristics of light weight, high strength, self-lubrication, wear resistance, corrosion resistance and insulation.

[0069] The ultra-high molecular weight polyethylene (UHMW-PE) is a thermoplastic engineering plastic with an average molecular weight greater than 1.5 million, which is polymerized by ethylene and butadiene monomers under the action of a catalyst. It has the performance advantages of wear resistance, low temperature resistance, corrosion resistance and impact resistance.

[0073] Reference Figure 4 and Figure 5In the embodiment of the present application, the plug 200 has a connecting end face, the connecting end face is away from the discharge port, the connecting end face has a connecting groove, a rigid connecting piece 201 is arranged in the connecting groove, and a first threaded hole is arranged on the rigid connecting piece 201.

[0074] The discharge assembly can further include an adapter plate 202 and a connecting piece 205, the adapter plate 202 is provided with a second threaded hole, and the connecting piece 205 is connected with the first threaded hole and the second threaded hole, so that the adapter plate 202 is connected to the connecting end face.

[0075] The adapter plate 202 is further provided with a first through hole and a second through hole, an end portion of the first driving shaft 3011 passes through the first through hole, so that the first driving shaft 3011 is connected to the adapter plate 202, and an end portion of the second driving shaft 3021 passes through the second through hole, so that the second driving shaft 3021 is connected to the adapter plate 202.

[0076] That is, the first driving shaft 3011 and the second driving shaft 3021 are connected to the plug 200 through the adapter plate 202; since the plug 200 made of non-metallic material is not rigid enough, the rigid connecting piece 201 is arranged on the plug 200, so that the rigid connecting piece 201 is connected to the adapter plate 202, and the connection strength of the plug 200 and the adapter plate 202 is improved.

[0077] The discharge assembly can further include a first nut 203 and a second nut 204, after the end portion of the first driving shaft 3011 passes through the first through hole, the first nut 203 and the second nut 204 are both sleeved on the end portion of the first driving shaft 3011. The first driving shaft 3011 is fixed on the adapter plate 202 through the double nuts, so as to prevent the first driving shaft 3011 from loosening.

[0078] Similarly, after the end portion of the second driving shaft 3021 passes through the second through hole, the first nut 203 and the second nut 204 are both sleeved on the end portion of the second driving shaft 3021. The second driving shaft 3021 is fixed on the adapter plate 202 through the double nuts, so as to prevent the second driving shaft 3021 from loosening.

[0079] Continuing to refer to Figure 5 In the embodiment of the present application, the projection of the adapter plate 202 on the first direction (X axis shown in the figure) covers the projection of the connecting end face on the first direction, so as to form a stepped surface at the connection between the adapter plate 202 and the connecting end face; that is, the diameter of the adapter plate 202 is greater than the diameter of the plug 200.

[0080] The discharge assembly can further include a sealing piece 800, the sealing piece 800 is arranged on the stepped surface, and the sealing piece 800 also wraps the adapter plate 202, so as to realize the sealing of the plug 200 and the opening, and the sealing of the adapter plate 202 and the opening.

[0081] It should be noted that the outer periphery of the plug 200 is provided with a limiting groove, and the sealing element 800 is embedded in the limiting groove while being arranged on the stepped surface, thereby improving the installation stability of the sealing element 800.

[0082] With reference to the foregoing Figure 1 In the embodiment, the discharging assembly further comprises a flange ring 700, which surrounds the outer periphery of the shell 100 and is close to the first side wall.

The stirring paddle comprises upper blades 123 and lower blades 124 arranged at intervals in the vertical direction (Z-axis shown in the figure). The lower blades 124 are arranged close to the bottom surface of the mixing tank 120. The stirring paddle is used for stirring the material in the mixing tank 120, and the upper blades 123 and the lower blades 124 cooperate to stir the material, so that the material is stirred more uniformly.

[0085] The mixing tank 120 comprises a tank body 122 and a bottom plate 125 connected to the tank body 122. The junction of the tank body 122 and the bottom plate 125 has a discharging port. The lower blades 124 are arranged close to the bottom plate 125, and the lower blades 124 can also push the material out of the discharging port.

[0086] In the embodiment, the opening of the discharging assembly 110 has a second central axis 130, which intersects the plane in which the bottom plate 125 lies. That is, the opening of the discharging assembly 110 is arranged obliquely relative to the tank body 122, so as to prevent the material from accumulating on the bottom plate 125 near the discharging port.

[0087] The angle between the second central axis 130 and the plane in which the bottom plate 125 lies can be 0°-30°.

[0088] In the embodiment, in the vertical direction (Z-axis shown in the figure), the lower blades 124 are lower than the highest point of the opening. That is, the upper end position of the opening of the discharging assembly is higher than the lower blades 124, so as to ensure that the material pushed by the lower blades 124 can be discharged from the opening of the discharging assembly.

[0089] In the embodiment of the present application, the plug 200 is plugged in the discharge port, and the plug 200 extends towards the center of the tank body 122 by a certain distance; that is, the plug 200 of the discharge assembly is closer to the center of the mixing tank 120, so as to avoid that part of the material remains at the bottom of the mixing tank 120.

[0090] In the embodiment of the present application, the ratio of the distance that the plug 200 extends towards the center of the tank body 122 to the radius of the tank body 122 ranges from 0.57 to 0.8, so as to prevent the plug 200 from interfering with the lower paddle 124.

[0091] Meanwhile, the double driving shafts of the embodiment of the present application can prevent the plug 200 from rotating, so as to prevent the plug 200 from being warped and to avoid that the plug 200 interferes with the lower paddle to cause material leakage.

[0092] In summary, the embodiment of the present application provides a discharge assembly and a mixing device. The discharge assembly comprises a shell 100, a plug 200 and a driving mechanism. The shell 100 has a first side wall and a second side wall 101 opposite to each other along a first direction (X axis shown in the figure), and the first side wall has an opening. The plug 200 is arranged in the shell 100, and the driving mechanism is arranged outside the shell 100 and on the second side wall 101. The driving mechanism has a first driving shaft 3011 and a second driving shaft 3021, both of which extend into the shell 100 from the second side wall 101 and are connected with the plug 200. The first driving shaft 3011 and the second driving shaft 3021 work simultaneously, the first driving shaft 3011 advances along the first direction (X axis shown in the figure), and the second driving shaft 3021 advances along the first direction (X axis shown in the figure), so that the first driving shaft 3011 and the second driving shaft 3021 simultaneously drive the plug 200 to move and extend out of the shell 100 from the opening. The first driving shaft 3011 retreats along the first direction (X axis shown in the figure), and the second driving shaft 3021 retreats along the first direction (X axis shown in the figure), so that the first driving shaft 3011 and the second driving shaft 3021 simultaneously drive the plug 200 to move and extend into the shell 100 from the opening. The double driving shafts are used for driving, both of which are connected with the plug 200. When the first driving shaft 3011 rotates relative to the driving mechanism, the second driving shaft 3021 will function as a limiting part, so as to restrict each other, prevent the plug 200 from rotating, and ensure that the plug 200 completely plugs the discharge port of the mixing device.
