[0002] EPP, polypropylene plastic foam material, is a highly crystalline polymer material with excellent performance. Its unique and superior performance has made it the fastest growing new environmentally friendly pressure-resistant, buffering and heat-insulating material. EPP products have excellent shock-absorbing performance, high recovery rate after deformation, good heat resistance, chemical resistance, oil resistance and heat insulation. In addition, its light weight can greatly reduce the weight of goods.

[0003] When the current pre-pressurization tank is pre-pressing EPP particles, the staff opens the pressure valve, and the EPP particles enter the pre-pressing tank through the EPP particle feeding pipe, and then enter the pre-pressing chamber through the one-way leakage net. The pressure valve is closed, so that the thrust plug inside the pre-pressing chamber moves up and down repeatedly, and the air in the pre-pressing chamber is repeatedly pre-pressed, thereby reciprocatingly pre-pressing the internal EPP particles. The one-way leakage net is cleaned or replaced during long-term use. However, due to the high pressure in the tank during the pre-pressing process, the one-way leakage net is always installed in a very stable manner and fixed in the tank, such as bolts, which makes it inconvenient to remove the one-way leakage net for cleaning or replacement.

[0020] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0021] The following is combined with Figure 1-3 The utility model is described in further detail.

[0022] The utility model embodiment discloses an EPP particle pre-compression tank. Figure 1-Figure 3 The EPP particle pre-pressing tank comprises a tank body 1 and a top cover 2 which can be fixed on the tank body 1, wherein a feeding pipe 21 for adding EPP particles into the tank body 1 is arranged on the top of the top cover 2, a pre-pressing bin 11 is arranged in the hollow inside of the tank body 1, a discharge pipe 12 is arranged near the bottom of the tank body 1, a thrust plug 13 which can be driven to move up and down is arranged in the pre-pressing bin 11, a one-way drop net 3 in an annular shape is arranged on the top of the pre-pressing bin 11, and a space for placing the one-way drop net 3 is opened on the top of the tank body 1 around the pre-pressing bin 11. The top cover 2 is provided with a pressing plate 22 for fixing the top cover 2 on the tank body 1 so as to press the edge of the one-way drop net 3 into the mounting groove 14. When installing, the one-way drop net 3 is placed in the mounting groove 14, and the top cover 2 is fixed to the tank body 1 with bolts. At the same time, the pressing plate 22 on the top cover 2 is pressed on the one-way drop net 2 to fix the one-way drop net 2 on the tank body 1. When disassembling, the top cover 2 is removed from the tank body 1, and the one-way drop net 3 can be directly removed from the tank body 1, so that the one-way drop net 3 can be easily cleaned and replaced.

[0023] In this embodiment, the pressure plate 22 is arranged in a ring shape and has an outer diameter that is the same as the diameter of the one-way drop net 3. The pressure plate 22 arranged in a ring shape can press the edge of the one-way drop net 3 into the mounting groove 14 without affecting the EPP particles from entering the pre-pressing bin 11 through the mesh holes of the one-way drop net 3. At the same time, the pressure plate 22 can also block the EPP particles and prevent the EPP particles from entering from the feed pipe 21 and then drifting to other positions on the top of the tank body 1, so that the EPP particles can only fall on the one-way drop net 3.

[0024] In this embodiment, picking grooves 15 are provided on both sides of the mounting groove 14 at the top of the tank body 1. The depth of the picking grooves 15 is the same as that of the mounting groove 14 and is connected to the mounting groove 14. Support ears 31 are provided on both sides of the one-way blanking net 3. The support ears 31 are located in the picking grooves 15 and the ends of the support ears 31 are spaced apart from the wall of the picking groove 15. When the one-way blanking net 3 needs to be removed from the tank body 1, the one-way blanking net 3 can be taken out through the two support ears 31 in the picking groove 15. The ends of the support ears 31 are spaced apart from the wall of the picking groove 15 to facilitate the staff to reach in and take it out.

[0025] In this embodiment, the thickness of the support ear 31 is smaller than the thickness of the one-way blanking net 3, and a gap is left between the bottom side of the support ear 31 and the bottom of the taking groove 15. When taking out the one-way blanking net 3, the staff's hand can reach into the gap between the bottom side of the support ear 31 and the bottom of the taking groove 15, which is convenient for the staff to hold the support ear 31 and take out the one-way blanking net 3.

[0026] In this embodiment, the tank body 1 is located below the pre-pressing bin 11 and is provided with a driving assembly 4 for driving the thrust plug 13 to move up and down. The driving assembly 4 includes an electric push cylinder 41 and a push rod 42. The push rod 42 is arranged at the telescopic end of the electric push cylinder 41 and extends vertically into the pre-pressing bin 11 and is connected to the bottom side of the thrust plug 13. The push rod 42 is pushed up and down by the electric push cylinder 41, thereby driving the thrust plug 13 to move up and down, thereby reciprocatingly pre-pressing the EPP particles in the pre-pressing bin 11.

[0027] In this embodiment, an inner drop tube 17 connected to the discharge tube 12 is provided on the side wall near the bottom of the pre-pressing bin 11. When the push plug 13 moves to the bottom of the pre-pressing bin 11, the inner drop tube 17 is located above the push plug 13 and the bottom wall is flush with the top of the push plug 13. This can prevent the push plug 13 from blocking the mouth of the inner drop tube 17 after the EPP particles are pre-pressed, causing the mouth of the inner drop tube 17 to become smaller, thereby preventing EPP particles from being blocked at the mouth of the inner drop tube 17.

[0028] In this embodiment, the tank body 1 is provided with an exhaust pipe 16, and the exhaust pipe 16 is provided with a controllable opening and closing valve. When the pressure in the pre-pressing chamber 11 is too high, the exhaust pipe 16 is opened to exhaust air and reduce the pressure in the pre-pressing chamber 11, making it safer to use.

[0029] In this embodiment, a pressure valve 23 for controlling the pressure in the pre-pressing bin 11 is provided on the feed pipe 21 , and the pressure in the pre-pressing bin 11 can be adjusted through the pressure valve 23 .

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
