[0002] Polypropylene particles are an important synthetic polymer material, with chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties, and good high-wear resistance processing properties, etc. They are commonly used in manufacturing plastic products, artificial fibers, pipes, etc. However, the rigidity and brittleness of polypropylene limit its application in some fields. Therefore, toughening treatment is often required, that is, a specific granular substance is added to the polypropylene material to enhance its toughness and mechanical properties. This process is usually used to improve the performance of polypropylene in practical applications, especially in occasions where higher impact resistance and strength are required;

[0003] In fields such as medical treatment and food packaging, there are particularly high requirements for the cleanliness and safety of materials. Therefore, during the toughening treatment of polypropylene materials, it is necessary to fully disinfect the materials to improve the safety of the toughened products.

[0025] Embodiment

[0026] Refer to the attached instructions Figures 1 - 5 , a sterilization device for toughening polypropylene particles, comprising a sterilization chamber 1, a feed inlet 11, an electric steam generator 3 and a discharge outlet 13. The feed inlet 11 and the discharge outlet 13 are both installed on one side of the sterilization chamber 1, the feed inlet 11 is located above the discharge outlet 13, the inner cavity of the sterilization chamber 1 is communicated with the outside through the feed inlet 11 and the discharge outlet 13, the electric steam generator 3 is installed on the sterilization chamber 1, and the output end is communicated with the inner cavity of the sterilization chamber 1;

[0027] An adjustment component is installed in the inner cavity of the sterilization chamber 1. The adjustment component includes a motor 14, a sterilization pipeline 15, a connecting pillar 16 and a limiting part. The sterilization pipeline 15 is installed in the inner cavity of the sterilization chamber 1 through the connecting pillar 16. The sterilization pipeline 15 is spirally wound and installed on the connecting pillar 16 through the limiting part. The connecting pillar 16 is rotatably connected with the inner cavity of the sterilization chamber 1. The motor 14 is fixedly installed on the top of the sterilization chamber 1. The output end of the motor 14 passes through the sterilization chamber 1 and is connected with the connecting pillar 16. One end of the sterilization pipeline 15 is fixedly installed at the upper end of the connecting pillar 16. One end of the sterilization pipeline 15 is detachably communicated with the feed inlet 11. The other end of the sterilization pipeline 15 passes through the discharge outlet 13 and is detachably communicated with the discharge outlet 13.

[0028] It should be noted that multiple groups of this device can be set. For example, one group can be set on the mixer to disinfect the above materials before the polypropylene material and the toughening material are mixed. Another group can be connected after the granulator to disinfect the toughened polypropylene particles formed by extrusion and granulation after the toughening material and the polypropylene material are mixed. In this embodiment, the toughened polypropylene particles are taken as an example for description. The sterilization pipeline 15 is set as a breathable elastic net. The toughened polypropylene particles after toughening treatment can enter the inner cavity of the sterilization chamber 1 through the feed inlet 11 and the sterilization pipeline 15 via the discharge port of the toughening equipment. At the same time, the electric steam generator 3 is used to discharge high-temperature steam into the sterilization chamber 1 to disinfect the materials in the inner cavity of the sterilization chamber 1. Then the materials flow along the sterilization pipeline 15 and are discharged through the discharge outlet 13, which can realize the function of continuously disinfecting the polypropylene particle materials. At the same time, the motor 14 is used to adjust the connecting pillar 16 to rotate a certain distance. Due to the fact that one end of the sterilization pipeline 15 is fixedly installed at the upper position of the connecting pillar 16 and the other end of the sterilization pipeline 15 can be fixedly connected to the discharge outlet 13, when the connecting pillar 16 drives the sterilization pipeline 15 to rotate, the tightness of the connection between the sterilization pipeline 15 and the connecting pillar 16 can be adjusted. When the connection between the sterilization pipeline 15 and the connecting pillar 16 is relatively loose, the distance between the inner walls of the sterilization pipeline 15 is relatively large. When the connection between the sterilization pipeline 15 and the connecting pillar 16 is relatively tight, the inner wall of the sterilization pipeline 15 is squeezed, and the distance between the inner walls is relatively close. Thus, it is convenient to adjust the continuous feeding speed of the materials, thereby facilitating the adjustment of the feeding rate and the disinfection efficiency, and improving the practicability.

[0029] Furthermore, the limiting member includes a fixed rail 161 and a fixed rubber strip 153. The sterilization pipe 15 is slidingly connected to the fixed rail 161 through the fixed rubber strip 153. The fixed rail 161 is spirally fixedly installed on the surface of the connecting pillar 16, and the fixed rubber strip 153 is fixedly installed on the surface of the sterilization pipe 15.

[0030] In the above embodiment, the fixed rail 161 is used to limit the fixed rubber strip 153, so that the sterilization pipe 15 can be slidably sleeved on the outside of the connecting pillar 16, so that the material can be evenly sterilized and discharged through the inner cavity of the sterilization box 1 through the sterilization pipe 15, thereby improving the practicality of the device.

[0031] Furthermore, a sleeve 152 is provided between the fixed rail 161 and the fixed rubber strip 153 , the fixed rail 161 is sleeved on the outside of the sleeve 152 , the sleeve 152 is movably connected to the fixed rail 161 , and the sleeve 152 is slidably sleeved on the outside of the fixed rubber strip 153 .

[0032] In the above embodiment, when the sterilization pipe 15 is tightly fitted with the connecting pillar 16, the inner walls of the sterilization pipe 15 are close to each other, so that the cross-sectional diameter of the sterilization pipe 15 becomes longer, so that the two ends of the sterilization pipe 15 are close to each other through the inner wall of the fixing rubber strip 153 and the inner wall of the sleeve 152. The sterilization pipe 15 is adjusted to fit tightly with the connecting pillar 16 to adapt to the fixed rail 161 and be installed on the connecting pillar 16. When the sterilization pipe 15 is relatively expanded, the inner wall of the fixing rubber strip 153 is away from the inner wall of the sleeve 152, so that the sterilization pipe 15 is adjusted to fit loosely with the connecting pillar 16 to adapt to the fixed rail 161 and be installed on the connecting pillar 16, so that the sterilization pipe 15 can fit easily with the fixed rail 161 and be installed on the connecting pillar 16.

[0033] Furthermore, a plurality of columns 151 are evenly and cross-distributed inside the sterilization pipe 15 , and the columns 151 are fixedly connected to the inner wall of the sterilization pipe 15 .

[0034] In the above embodiment, the columns 151 increase the flow resistance of the polypropylene particles in the inner cavity of the sterilization pipe 15, so that the material particles roll when contacting each column 151, thereby extending the disinfection time of the polypropylene particles and effectively improving the disinfection effect.

[0035] Furthermore, a limiting door 131 is slidably installed on the discharge port 13, and the limiting door 131 is used to close the discharge port 13. The top of the limiting door 131 is rotatably connected to a rotating shaft 132, and the top of the rotating shaft 132 passes through the top of the discharge port 13, and the rotating shaft 132 is threadedly connected to the top of the discharge port 13.

[0036] In the above embodiment, by rotating the rotating shaft 132, the limiting door 131 slides at the discharge port 13, which facilitates adjusting the size of the discharge port 13, and the limiting door 131 is used to conveniently position the sterilization pipeline 15, and cooperate with the connecting support column 16 to adjust the tightness degree of the sterilization pipeline 15 and the feeding rate.

[0037] Furthermore, a plurality of spray heads 31 are arranged in the inner cavity of the sterilization box 1, and the plurality of spray heads 31 are jointly connected to the output end of the electrothermal steam generator 3.

[0038] In the above embodiment, the electrothermal steam generator 3 disinfects the inner cavity of the sterilization box 1 more efficiently through the plurality of spray heads 31, and high-temperature steam is evenly distributed to disinfect the material without dead angles.

[0039] Furthermore, an adjusting blade 12 is rotatably arranged inside the feed inlet 11, a maintenance door 2 is arranged on the surface of the sterilization box 1, a collection box 21 is arranged at the bottom of the maintenance door 2, and the collection box 21 is detachably connected to the inner cavity of the sterilization box 1.

[0040] In the above embodiment, the feed inlet 11 is closed by the adjusting blade 12, and the material contacts the adjusting blade 12 and makes the adjusting blade 12 rotate due to gravity, and then enters the inner cavity of the sterilization box 1. The collection box 21 can conveniently collect the debris falling inside the material.

[0041] In this embodiment, the implementation scenario is specifically as follows: when the device is in use, the toughened polypropylene particles enter the inner cavity of the sterilization box 1 through the feed inlet 11 from the discharge port of the toughening equipment, and at the same time, the electrothermal steam generator 3 discharges high-temperature steam into the sterilization box 1. The high-temperature steam is evenly sprayed on every corner of the inner cavity of the sterilization box 1 through the spray heads 31. At the same time, the material inside the sterilization pipeline 15 is evenly heated to achieve dead-angle-free disinfection. Then the material flows along the sterilization pipeline 15 and is discharged through the discharge port 13, which can realize the function of continuously disinfecting the polypropylene particle material. At the same time, cooperate with the motor 14 to adjust the connecting support column 16 to rotate a certain distance. Since one end of the sterilization pipeline 15 is fixedly installed at a position above the connecting support column 16, and the other end of the sterilization pipeline 15 is positioned by the limiting door 131, when the connecting support column 16 drives the sterilization pipeline 15 to rotate, the tightness degree of the connection between the sterilization pipeline 15 and the connecting support column 16 can be adjusted. When the connection between the sterilization pipeline 15 and the connecting support column 16 is relatively loose, the distance between the inner walls of the sterilization pipeline 15 is relatively large. When the connection between the sterilization pipeline 15 and the connecting support column 16 is relatively tight, the inner wall of the sterilization pipeline 15 is squeezed, and the distance between the inner walls is relatively close. Thus, it is convenient to adjust the continuous feeding speed of the material, and it is also convenient to adjust the feeding rate and the disinfection efficiency, improving the practicability of the device.

[0042] Finally: The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
