Description

Technical Field

[0001] This utility model belongs to the field of PP material processing technology, and in particular relates to a PP modified material raw material mixing device. Background Technology

[0002] In the current PP material processing technology field, PP material is polypropylene, which is a non-toxic, odorless, tasteless, milky white, highly crystalline polymer. Modified polypropylene requires the addition of various antioxidants during processing. The antioxidants are mixed with the base material after heating, so a mixing device is needed to improve the processing efficiency of modified PP materials and make the mixing more uniform.

[0003] Utility model patent CN210045136U discloses a mixing device for UPE antistatic modified material raw materials, which solves the shortcomings of slow mixing rate and low efficiency in the prior art. The device includes a housing with a feed pipe welded to the top and a control panel installed on its side wall. A mixing chamber is opened inside the housing, and a stirrer is installed inside the mixing chamber via a motor. A discharge pipe with a solenoid valve is installed at the bottom of the mixing chamber. This utility model heats water using an electric heating wire and utilizes sand in the interlayer to rapidly transfer heat to the mixing chamber, raising the temperature inside and accelerating the fusion rate, thus improving work efficiency. Simultaneously, a circulating pump circulates the water in the heating pipe, creating water flow and thus more evenly conducting heat to the outer wall of the mixing chamber.

[0004] However, the aforementioned patents have the following shortcomings:

[0005] The aforementioned patent raises the water temperature by heating the heating wire, thereby raising the temperature of the mixing chamber and making the raw materials heat up faster and more evenly. However, in actual processing, modified plastic materials such as polypropylene become sticky after being heated and are easily left in the stirring structure. At the same time, when mixing other materials, the interior needs to be cleaned, and manual cleaning is inefficient, reducing the processing efficiency of the modified materials. Utility Model Content

[0012] Preferably, a bevel gear one is fixedly mounted on the drive shaft, and a geared motor is fixedly mounted on the upper surface of the mixing tank. A bevel gear two that meshes with the bevel gear one is mounted on the output end of the geared motor. In this scheme, the geared motor drives the drive shaft through gear transmission, thereby driving the mixing shaft to rotate and mixing the raw materials inside the mixing tank.

[0013] Preferably, a mixing shaft is fixedly installed on the lower surface of the rotating disk, and a plurality of mixing rods are installed on the outer wall of the mixing shaft, with the plurality of mixing rods evenly distributed on the outer wall of the mixing shaft;

[0014] Furthermore, stirring rods are installed on the outer walls of multiple mixing rods, and the multiple stirring rods are arranged alternately on the outer walls of multiple mixing rods; in this scheme, multiple mixing rods and stirring rods rotate with the mixing shaft, resulting in a higher contact area with the raw materials and more uniform mixing.

[0015] Preferably, the inner wall of the mixing tank is fitted with heating wires;

[0016] Furthermore, the inner wall of the mixing tank is provided with an insulation layer, and the interior of the insulation layer is filled with insulation material; in this solution, the temperature inside the mixing tank is increased by heating wire, and at the same time, the insulation layer improves the insulation performance of the mixing tank, making it less prone to heat loss.

[0023] 2. The rotating disc is equipped with multiple top blocks with inclined surfaces. Meanwhile, the top wall inside the mixing tank is rotatably mounted with support wheels via a bracket. When the rotating disc rotates, the support wheels slide into the top wall of the top blocks through the inclined surfaces, thereby contacting the top wall and causing the rotating disc to descend. The rotating disc is then reset via a connecting spring, which in turn causes the rotating disc to move longitudinally, causing the mixing shaft and mixing rod to vibrate. This prevents raw materials from sticking to the surface and makes cleaning easier.

[0024] 3. The mixing tank is equipped with a ring-shaped water guide pipe. Multiple nozzles are installed at the bottom of the water guide pipe.

[0036] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0037] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0038] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0039] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] Please see Figure 1-4 This utility model provides a technical solution: a PP modified material raw material mixing device, including a mixing tank 1, with multiple support legs 11 with pads installed at the bottom of the mixing tank 1, and a mixing mechanism 2, which includes a drive shaft 21, which is rotatably installed inside the mixing tank 1. A circular rotating frame 212 is fixedly installed at the lower end of the drive shaft 21, and multiple connecting springs 231 are fixedly connected to the lower end of the rotating frame 212. A rotating disk 23 is fixedly connected to the lower end of the multiple connecting springs 231, and the multiple connecting springs 231 are evenly arranged around the center point of the rotating disk 23. Multiple top blocks 232 with inclined surfaces are fixedly installed on the upper surface of the rotating disk 23, and the multiple top blocks 232 are evenly arranged around the center point of the rotating disk 23. Two support wheels 233 are installed on the top wall inside the mixing tank 1 through two brackets, and the two support wheels 233 are arranged above the rotating disk 23.

[0042] When the drive shaft 21 rotates, it drives the rotating frame 212 and the rotating disk 23 to rotate. When the rotating disk 23 rotates, the support wheels 233 slide into the top of the top block 232 when the multiple top blocks 232 pass through the inclined surface, and then abut against the top block 232, causing the rotating disk 23 to descend. When the top block 232 no longer abuts against the support wheel 233, the elasticity of the connecting spring 231 drives the rotating disk 23 to reset, causing the rotating disk 23 to vibrate longitudinally, preventing the raw materials from sticking to the mixing shaft 24.

[0043] A bevel gear 211 is fixedly mounted on the drive shaft 21, and a geared motor 22 is fixedly mounted on the upper surface of the mixing tank 1. A bevel gear 221 that meshes with the bevel gear 211 is mounted on the output end of the geared motor 22. A mixing shaft 24 is fixedly mounted on the lower surface of the rotating disk 23. Multiple mixing rods 241 are mounted on the outer wall of the mixing shaft 24. The multiple mixing rods 241 are evenly distributed on the outer wall of the mixing shaft 24, and stirring rods 242 are mounted on the outer wall of each of the multiple mixing rods 241. The multiple stirring rods 242 are arranged alternately on the outer wall of the multiple mixing rods 241.

[0044] Among them, the geared motor 22 drives the drive shaft 21 to rotate through gear transmission, which in turn drives the mixing shaft 24, as well as multiple mixing rods 241 and stirring rods 242 to rotate, and has a larger contact area with the raw materials, resulting in more uniform mixing.

[0045] The inner wall of the mixing tank 1 is fitted with an electric heating wire 14, and the inner wall of the mixing tank 1 is provided with a heat insulation layer 15, which is filled with heat insulation material.

[0046] Furthermore, the heating wire 14 raises the temperature inside the mixing tank 1, facilitating the melting of the raw materials. Meanwhile, the insulation material inside the insulation layer 15 can be rock wool, which improves the insulation of the mixing tank 1 and further enhances the melting efficiency of the raw materials.

[0047] The bottom of the mixing tank 1 is provided with a conical discharge port 12, a discharge valve 121 is installed on the discharge port 12, and a feed hopper 13 is installed on the mixing tank 1. The mixing tank 1 is also equipped with a pressure relief valve 16 through a pipeline.

[0048] Specifically, the mixed raw materials are discharged through the discharge port 12 and the discharge valve 121. At the same time, a sealing cover is installed on the feed hopper 13 to reduce the loss of internal heat. After processing, the pressure relief valve 16 is opened to reduce the internal pressure and prevent the discharge valve 121 from being damaged by excessive internal pressure.

[0049] It also includes a rinsing mechanism 3, which includes an annular water guide pipe 31. The water guide pipe 31 is fixedly installed on the top wall of the inner wall of the mixing tank 1. Multiple nozzles 311 are installed on the bottom wall of the water guide pipe 31. The multiple nozzles 311 are evenly distributed on the water guide pipe 31. A water inlet valve 32 is fixedly installed on the water guide pipe 31 and is located on the outer wall of the mixing tank 1.

[0050] What is needed is that the water inlet valve 32 is connected to a water source to deliver the cleaning water to the annular water guide pipe 31, and spray it out by multiple nozzles 311 to rinse the inner wall of the mixing tank 1, so that the wastewater is discharged through the discharge valve 121, making cleaning easier.

[0051] The working principle and usage process of this utility model are as follows: Please refer to... Figure 1-4 Raw materials are poured into the feed hopper 13. The geared motor 22 drives the drive shaft 21 to rotate via gear transmission, which in turn drives the mixing shaft 24, multiple mixing rods 241, and stirring rods 242 to rotate. The heating wire 14 raises the temperature inside the mixing tank 1 to facilitate the melting of the raw materials. When the drive shaft 21 rotates, it drives the rotating frame 212 and the rotating disk 23 to rotate. When the rotating disk 23 rotates, multiple top blocks 232 slide onto the top blocks 232 above the inclined surface using support wheels 233, thereby contacting the top blocks 232 and causing the rotating disk 23 to descend. When the support wheel 233 is pressed again, the elasticity of the connecting spring 231 drives the rotating disk 23 to reset, causing the rotating disk 23 to vibrate longitudinally, preventing the raw materials from sticking to the mixing shaft 24. After mixing is completed, the pressure relief valve 16 is opened to reduce the internal pressure, and the mixed raw materials are discharged through the discharge port 12 and the discharge valve 121. After the raw materials are completely discharged, the water inlet valve 32 is connected to the water source to deliver the cleaning water to the annular water guide pipe 31, and sprayed out by multiple nozzles 311 to rinse the inner wall of the mixing tank 1, so that the wastewater is discharged through the discharge valve 121.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
