Description

Technical Field

[0001] The utility model belongs to the technical field of waste recycling equipment, in particular to a waste plastic barrel compression device. Background Art

[0002] After a plastic barrel has been used for too long, its material tends to become brittle, which reduces its structural strength and makes it impossible to continue to use it. Discarding it at will will cause a certain amount of resource waste and pollute the environment. In order to improve the utilization rate of materials, they are generally recycled. When recycling these waste barrels, they need to be crushed and compressed first, and then melted. Then, some auxiliary color matching materials can be added to shape them into new products.

[0003] At present, when compressing waste plastic barrels, pulverizers or crushers are generally used to directly pulverize the plastic barrels, but such equipment can only compress the volume of waste plastic barrels and cannot directly melt them. To solve this problem, after searching, a Chinese utility model patent with publication number CN218365919U has disclosed a waste plastic barrel recycling and processing device, which includes a pulverizing roller and a cutting rod to preliminarily pulverize the waste plastic barrels, and also includes a rear end heating extrusion cylinder and an auger conveying shaft and other components, so that the pulverized plastic is heated and melted while being extruded. After analysis, the inventor believes that its structure still has certain defects: the heating part of the heating extrusion cylinder is located in the cylinder wall, and the plastic fragments must touch the cylinder wall to be heated and quickly melted. Since the thermal conductivity of the plastic itself is poor, the plastic fragments far away from the cylinder wall or always unable to touch the cylinder wall are difficult to be heated, resulting in insufficient melting. If the heating power is increased, it will cause power consumption waste. Utility Model Content

[0005] In view of the following technical problems in the prior art: when compressing plastic barrels, the compressed plastic fragments are not heated uniformly due to structural reasons, resulting in incomplete melting.

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0029] Reference Figure 1-6 An embodiment of the utility model provides a waste plastic barrel compression device, including a crushing part 1 for physically crushing the waste plastic barrel in the current technology, and a heating source 2. The crushing part 1 can still use a crushing roller or other crushing mechanisms. The heating source 2 is used to generate heat, such as a heating wire or other components. The device also includes the following parts:

[0030] The storage box 3 and the extrusion piece 4 slidably arranged in the storage box 3, the extrusion piece 4 needs to always fit with the inner cavity of the storage box 3, so as to meet the sliding requirements of the accumulated pieces and maintain the lateral interception of the inner cavity of the storage box 3. For this reason, the storage box 3 shown in the figure is a cylindrical structure, and the extrusion piece 4 is also a columnar structure, which is used as a reference. An electric cylinder 15 is connected between the extrusion piece 4 and the storage box 3, so as to push the accumulated pieces to slide vertically. The crushing part 1 is connected to the storage box 3, specifically, it can be connected to one side wall of the storage box 3 through a blanking channel 16. The storage box 3 has an air inlet 5 and an air outlet 6. In addition, the storage box 3 is also equipped with a discharge port 17 that can be opened and closed manually for discharging molten plastic;

[0031] The air guide pipe 7 is connected between the air inlet 5 and the air outlet 6, so as to form a circular communication structure with the storage box 3. Figure 1 The appearance of the air guide pipe 7 is omitted in the figure. For details, please refer to Figure 6 ,like Figure 6 As shown, the entire air guide pipeline 7 cooperates with the storage box 3 to form a closed loop structure, and an airflow driving mechanism 8 is also provided on the path of the air guide pipeline 7 to make the air in the closed loop structure circulate. The airflow driving mechanism 8 can be a blower, a fan or an air pump, and the heating source 2 is provided on the path of the air guide pipeline 7;

[0032] Based on the above, the discarded plastic barrels are crushed by the crushing part 1, and then fall to the bottom of the storage box 3. Then, through the cooperation of the heating source 2 and the airflow pushing mechanism 8, the air in the storage box 3 circulates and is continuously heated by the heating source 2, so that the heat of the heating source 2 is evenly filled into the storage box 3 through the airflow, thereby heating the plastic fragments until they are melted. Finally, the molten plastic is squeezed to the outside of the discharge port 17 by the extrusion part 4. Compared with the prior art, in the whole process of heating the fragments, the fragments in the present device are mainly heated by contact with hot air rather than by contact with the box wall. Moreover, the fragments are non-fluid and there are gaps between them, so that the hot air can still penetrate into the accumulated fragments. Therefore, the present device makes the plastic fragments heat more evenly, and therefore melts more thoroughly, which can better facilitate further processing later.

[0033] Further, see Figure 3 and Figure 4 The connection point between the storage box 3 and the crushing part 1 is movably connected with a partition 9. The movable connection method here can be a method of hingedly connecting the top of the partition 9 with the top of the blanking channel 16. Through the action of gravity, the partition 9 always hangs in a vertical state, thereby blocking the channel. When fragments fall from the blanking channel 16, the fragments can automatically push the partition 9 away, thereby not hindering their falling into the storage box 3. The setting of the partition 9 here can reduce the phenomenon of air circulating in the storage box 3 and flowing out along the connection point, thereby reducing heat loss and improving energy utilization.

[0034] Further, see Figure 3 and Figure 4 The device also has this structural relationship: when the extrusion member 4 is in the process of sliding down or when it slides to the bottom, the extrusion member 4 will form a blockage on one side of the partition 9, so that the partition 9 cannot be pushed away by the fragments, so that the fragments cannot enter the storage box 3 during the extrusion of the extrusion member 4. This design can prevent the extrusion member 4 from being stuck by the fragments that fall in when the extrusion member 4 slides, and at the same time prevent the fragments that fall into the storage box 3 in a short period of time from being discharged together without being melted in time; regarding the blocking method of the extrusion member 4 on the partition 9, the setting position of the partition 9 can be close to the end of the blanking channel 16, so that the extrusion member 4 forms a blockage on one side of the partition 9 when it slides down.

[0035] Further, see Figure 3 and Figure 4A buffer cavity 10 is formed between the top of the extrusion piece 4 and the storage box 3, and the buffer cavity 10 can facilitate the installation of the electric cylinder 15. The extrusion piece 4 is provided with a vent hole 11 that keeps its bottom connected to the buffer cavity 10, and a cover piece 12 is provided at the vent hole 11. When the bottom of the extrusion piece 4 is subjected to force, the cover piece 12 will form a cover for the vent hole 11; based on this, when the extrusion piece 4 slides down and starts to extrude the molten plastic, in this process, when the bottom of the extrusion piece 4 has not yet contacted the molten plastic, its bottom is not subjected to force, and the vent hole 11 is in an open state, so that the hot air in the cavity on one side of the bottom of the extrusion piece 4 in the storage box 3 can be squeezed into the top of the extrusion piece 4 along the vent hole 11 The vent 11 is opened again after the extruder 4 has completed the extrusion work and rises, so that part of the hot air can return to the storage chamber below the extruder 4, so that when the next batch of plastics is hot-melted, this part of the heat can be used to reduce the heating time of the air, thereby saving energy for the device.

[0036] Further, see Figure 3 and Figure 4 The covering member 12 includes a cover plate 12a movably arranged at the vent hole 11. The cover plate 12a can be slidably arranged on the extrusion member 4 through a plurality of connecting columns. The cover plate 12a is located on one side of the bottom of the extrusion member 4, and its plate area is larger than the mouth area of ​​the vent hole 11. Therefore, when the bottom of the extrusion member 4 contacts the molten plastic, the cover plate 12a is lifted up by the extrusion force, thereby covering the vent hole 11. When the extrusion member 4 is lifted and reset, the cover plate 12a is placed in a hanging hammer state by gravity, thereby separating from the vent hole 11 to release the cover.

[0037] Further, see Figure 3-5 The air inlet 5 is located at the bottom of the storage box 3 and is evenly distributed in multiple places. The air outlet 6 is located on the side wall of the storage box 3 and is also evenly distributed in multiple places. By setting the air inlet 5 and the air outlet 6 to multiple places, the uniformity of the distribution of the circulating airflow in the storage box 3 can be improved. The air inlet 5 is set at the bottom of the storage box 3, so that when the gas of the circulating airflow enters the storage box 3, the accumulated plastic fragments can be blown upward, thereby turning the plastic fragments over, so as to better facilitate the hot air to fill the accumulated plastic fragments, thereby increasing the uniformity of heating.

[0038] Further, see Figure 4 and Figure 5 A sealing plate 13 is also movably provided at the air inlet 5. The sealing plate 13 is located on one side of the top of the air inlet 5. Its working principle is consistent with and just opposite to that of the cover plate 12a. When hot air needs to be blown into the storage box 3 from the air inlet 5, the sealing plate 13 will be lifted up to ensure the entry of airflow. When the airflow stops flowing, the sealing plate 13 is not subjected to air thrust, and it will move down to cover the air inlet 5 under the pressure of the molten plastic, thereby preventing the plastic from falling into the air inlet 5 to prevent the air inlet 5 from being blocked. Regarding the installation method of the sealing plate 13, it can still form a vertical sliding relationship with the storage box 3 through a connecting column.

[0039] Further, see Figure 6 The device also includes a filter assembly 14 disposed on the path of the air guide pipe 7, and the flow direction of the air flow is as follows Figure 6 As shown by the middle arrow, through the cooperation of the filter component 14, when the air coming out of the storage box 3 can pass through the filter component 14, when there are some toxic gases or particulate matter in the air, they can be effectively intercepted by the filter component 14, so as to reduce the particulate matter or exhaust gas being discharged to the outside along the gap at the blanking channel 16, thereby reducing the pollution to the surrounding environment. In addition, it can also reduce the phenomenon of particulate matter adhering to the heating source 2 and the airflow driving mechanism 8, so as to increase the practicality of the device. For the filter component 14, in actual use, specific objects such as filter nets or activated carbon can be used.

[0040] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0041] 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 spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
