Description

Technical Field

[0001] The invention belongs to the technical field of pressure working equipment, and in particular relates to compression and packaging equipment for solid waste treatment. Background Art

[0002] Solid waste extrusion is a common waste pretreatment method used to reduce waste volume and improve the efficiency of subsequent processing or disposal. It mainly works by forming an extrusion zone inside the extrusion device and hard extruding and compressing the material through various driving methods such as hydraulic pressure. The most common method is to extrude the material into rectangular blocks for subsequent packaging and stacking transportation. Common solid wastes that are compressed, extruded and packaged are generally metals, paper, plastics and other materials with high recycling value. With the improvement of people's living standards, bottled beverages have gradually become an indispensable part of people's lives. Therefore, the amount of bottled mineral water that has not been recycled is also increasing year by year, causing great pollution to the environment.

[0003] In the existing technology for compressing plastic bottles, a horizontal compression method is generally used. This method has certain defects in the actual working process: first, for the compression of plastic materials, such as common plastic bottles, the plastic itself has a certain elasticity and toughness, and it is easy to become loose again after being squeezed. Secondly, the elasticity and toughness of the plastic product itself can easily lead to the formation of cavities inside the compressed plastic material. Especially for plastic bottles, which are generally covered and may be in a sealed state inside, it is very difficult to squeeze the plastic bottle completely without unscrewing the cover during compression. It is also easy to burst during overpressure extrusion, causing vibration inside the extruded material and further causing it to loosen, which is more likely to cause poor compression efficiency and easy loosening. Therefore, it is necessary to improve the existing plastic material recycling and extrusion mechanism. Summary of the invention

[0004] The object of the present invention is to provide a compression and packaging device for solid waste treatment to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a compression and packaging device for solid waste treatment, comprising a material chamber, an extrusion plate arranged in the material chamber, and a first hydraulic rod driving the extrusion plate to slide linearly, the back of the extrusion plate is fixedly connected to a plurality of sleeves arranged equidistantly, an air cavity is provided inside the sleeve, and an inflation head is fixedly connected to one end of the sleeve, one end of the air cavity is fixedly connected to one end of a return spring, the other end of the return spring is fixedly connected to a slider slidably sleeved with the air cavity, the end of the slider away from the return spring is fixedly connected to a puncture needle, the puncture needle passes through a through hole provided in the extrusion plate, a melting device is provided inside the puncture needle, and an air blowing device is provided inside the sleeve; The melting device comprises two upper and lower groups of power connection blocks fixedly installed inside the through hole and a heating rod fixedly installed inside the puncture needle, one end of the heating rod is fixedly connected to two groups of conductive blocks, the two groups of conductive blocks are installed on the surface of the puncture needle and are adapted to the positions of the two groups of power connection blocks; The blowing device includes two groups of guide tubes opened in the wall thickness of the sleeve, one end of the guide tube is connected to the air cavity close to the inflation head, and an electromagnetic valve is arranged inside the guide tube, and the other end of the guide tube is connected to an annular cavity arranged outside the through hole on the extrusion plate, and the annular cavity is provided with a plurality of groups of equally circumferentially distributed conical channels toward the inner side of the through hole.

[0006] Preferably, the material cabin includes a bottom plate, side plates are fixedly connected to both sides of the upper surface of the bottom plate, one end of the side plate is fixedly connected to a back plate, a first hydraulic rod is fixedly installed on the middle part of the back plate, an extended end of the first hydraulic rod is fixedly connected to an extrusion plate, a support seat is fixedly installed on the upper end of the back plate, a second hydraulic rod is rotatably sleeved on the upper part of the support seat, an extended end of the second hydraulic rod is fixedly connected to an upper cover plate, one end of the upper cover plate is rotatably sleeved on the upper parts of the side plates on both sides, both sides of the other end of the side plate are fixedly connected to fixed seats, sliding grooves are provided on the inner sides of the two groups of the fixed seats, third hydraulic rods are fixedly installed on the bottoms of the two groups of the fixed seats, and baffles slidably connected to the sliding grooves are fixedly connected to the extended ends of the two groups of the third hydraulic rods.

[0007] Preferably, a through hole communicating with the outside air is formed on a side surface of the air cavity away from one end of the inflation head.

[0008] Preferably, the puncture needle is made of steel, and has a pointed tip at its front end, and is a cylindrical body with a smooth surface as a whole.

[0009] Preferably, an insulating layer is provided between the power connection block, the conductive block, the extrusion plate, and the puncture needle, respectively.

[0010] Preferably, a sealing sleeve is provided at one end of the inner wall of the through hole close to the sleeve, and the tapered channel is in an inclined state, and the closer to the inner wall of the through hole, the smaller the inner diameter.

[0011] The beneficial effects of the present invention are as follows: 1. The present invention can control the extension of the first hydraulic rod during operation through the arrangement of the sleeve, the air cavity, the return spring and the puncture needle, so as to push the extrusion plate to extrude the plastic material in the extrusion zone. At this time, since the solenoid valve and the inflation head are both in a closed state, the slider cannot move in the air cavity, so that the puncture needle will penetrate into the plastic material as the extrusion plate moves, and the puncture needle punctures the plastic material, and the extrusion plate extrude the punctured plastic material. The puncture can not only accelerate the rapid discharge of air in the cavity existing in the plastic material during extrusion, but also avoid the problem that the bottle material in the plastic material cannot discharge its internal air due to its own sealing, resulting in the formation of a cavity inside the extruded material, resulting in a poor extrusion effect.

[0012] 2. The present invention, through the arrangement of the melting device and the puncture needle, can, during the process of the puncture needle piercing the plastic material, energize the heating rod to rapidly heat up the heating rod due to the contact between the power connection block and the conductive block, and rapidly heat up the puncture needle by heat conduction, and can contact and heat the plastic material of the puncture needle to partially melt the plastic material. The melted plastic liquid can not only reduce the puncture resistance of the puncture needle, but also fill the gap inside the compressed material. Moreover, the melted part of the solution contacts the plastic solution near it, and will cool and condense at a position away from the puncture needle or after the puncture needle is separated from the material, so that the extruded plastic materials can adhere to each other, rather than just relying on hard extrusion force to stick together, so as to avoid loosening due to factors such as vibration during subsequent transportation, resulting in loosening of the extruded material or even complete dispersion.

[0013] 3. The present invention, through the arrangement of the blowing device and the through hole, can control the third hydraulic rod to extend after the extrusion is completed, drive the baffle to move up, and then control the first hydraulic rod to shorten and open the solenoid valve at the same time. At this time, the reset spring can drive the slider to move inside the air cavity under its own rebound action, and blow the air inside the air cavity out of the tapered channel through the guide tube and the annular cavity, so as to remove the plastic solution attached to the surface of the puncture needle, and avoid the plastic solution attached to the surface of the puncture needle, which will cause the cooling of the plastic solution in the subsequent working process, resulting in the attachment of cooling plastic particles to the surface of the puncture needle and affect the subsequent normal operation of the puncture needle, and the high-speed airflow during the blowing process will accelerate the cooling of the plastic solution inside the extruded material, ensuring that the material is quickly adhered to after extrusion.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] like Figures 1 to 7 As shown, an embodiment of the present invention provides a compression packaging device for solid waste treatment, including a material chamber, an extrusion plate 5 arranged in the material chamber, and a first hydraulic rod 4 driving the extrusion plate 5 to slide linearly, a plurality of groups of sleeves 13 arranged equidistantly are fixedly connected to the back of the extrusion plate 5, an air cavity 14 is provided inside the sleeve 13, and an inflation head 15 is fixedly connected to one end of the sleeve 13, one end of a return spring 16 is fixedly connected to the inside of the air cavity 14, and a slider 17 slidably sleeved with the air cavity 14 is fixedly connected to the other end of the return spring 16, and a puncture needle 18 is fixedly connected to the end of the slider 17 away from the return spring 16, the puncture needle 18 is made of steel material, and a tip is provided at the front end, and the whole is a smooth cylindrical body, the puncture needle 18 passes through the through hole provided on the extrusion plate 5, a melting device is provided inside the puncture needle 18, and a blowing device is provided inside the sleeve 13; The melting device includes two sets of power connection blocks 19 fixedly installed inside the through hole from top to bottom and a heating rod 20 fixedly installed inside the puncture needle 18. One end of the heating rod 20 is fixedly connected with two sets of conductive blocks 21. The two sets of conductive blocks 21 are installed on the surface of the puncture needle 18 and are adapted to the positions of the two sets of power connection blocks 19. Insulating layers are provided between the power connection blocks 19, the conductive blocks 21 and the extrusion plate 5, the puncture needle 18 respectively. After the puncture needle 18 is completely inserted into the plastic material, at this time the power connection blocks 19 are in contact with the conductive blocks 21, and the heating rod 20 can be powered on, so that it can quickly heat up, and conduct heat to make the puncture needle 18 quickly heat up, and can contact and heat the plastic material of the puncture needle 18 to make it partially melt. The melted plastic liquid will not only fill the gaps inside the compressed material, but also the melted part of the solution contacts the plastic solution nearby and will condense after cooling, so that the extruded plastic materials can be connected together, rather than just being pressed together by hard extrusion force, and the extruded plastics themselves can be adhered together, avoiding loosening due to vibration and other factors during subsequent transportation, resulting in the extrusion material being loose or even completely scattered; The air blowing device includes two sets of diversion pipes 22 opened in the wall thickness of the sleeve 13. One end of the diversion pipe 22 is communicated with the air chamber 14 on the side close to the inflation head 15, and a solenoid valve 23 is arranged inside the diversion pipe 22. The other end of the diversion pipe 22 is connected with an annular chamber 24 arranged outside the through hole on the extrusion plate 5. A number of conical channels 25 distributed equidistantly in a circumferential direction are opened on the inner side of the annular chamber 24 facing the through hole. A sealing sleeve is arranged at one end of the inner wall of the through hole close to the sleeve 13. The conical channels 25 are in an inclined state, and the inner diameter is smaller closer to the inner wall of the through hole. By controlling the shortening of the first hydraulic rod 4 and opening the solenoid valve 23 at the same time, at this time the return spring 16 can drive the slider 17 to move inside the air chamber 14 under its own elastic return action, and blow the air inside the air chamber 14 out from the conical channels 25 through the diversion pipes 22 and the annular chamber 24, so as to remove the plastic solution adhered to the surface of the puncture needle 18, avoiding the plastic solution adhered to the surface of the puncture needle 18, resulting in the surface of the puncture needle 18 being adhered with cooled plastic particles due to the cooling of the plastic solution during the subsequent working process, which affects the subsequent normal working of the puncture needle 18. During the retraction process of the puncture needle 18, due to the residual heat on its surface and the lubricity of the plastic solution, it can avoid the puncture needle 18 being unable to be pulled out from the extrusion material under the extrusion action of the material.

[0018] Among them, the material cabin includes a bottom plate 1, both sides of the upper surface of the bottom plate 1 are fixedly connected with side plates 2, one end of the side plate 2 is fixedly connected with a back plate 3, the middle of the back plate 3 is fixedly installed with a first hydraulic rod 4, the extended end of the first hydraulic rod 4 is fixedly connected with an extrusion plate 5, the upper end of the back plate 3 is fixedly installed with a support seat 6, the upper part of the support seat 6 is rotatably sleeved with a second hydraulic rod 7, the extended end of the second hydraulic rod 7 is fixedly connected with an upper cover plate 8, one end of the upper cover plate 8 is rotatably sleeved on the upper parts of the side plates 2 on both sides, both sides of the other end of the side plate 2 are fixedly connected with fixed seats 9, the inner sides of the two groups of fixed seats 9 are provided with sliding grooves 10, the bottoms of the two groups of fixed seats 9 are fixedly installed with third hydraulic rods 11, and the extended ends of the two groups of third hydraulic rods 11 are fixedly connected with baffles 12 slidably connected to the sliding grooves 10.

[0019] Among them, a through hole connected to the outside air is opened on the side of the air cavity 14 away from one end of the inflation head 15. The setting of the inflation head 15 makes it possible to control the extension length of the puncture needle 18 by controlling the amount of air filled from the inflation head 15 before work, so as to adapt to different compression sizes. At the same time, it is also possible to ensure that the puncture needle 18 can perform the puncture work normally by closing the inflation head 15 and the solenoid valve 23 when the puncture needle 18 is puncturing.

[0020] Working principle: Before the present invention works, the third hydraulic rod 11 drives the baffle plate 12 to move downward in the chute 10 to block the front end of the extrusion zone, the first hydraulic rod 4 contracts to control the extrusion plate 5 to be in the initial position, and then the plastic material to be extruded is poured into the extrusion zone. After the plastic material is filled, the second hydraulic rod 7 extends to press the upper cover plate 8 downward to block the upper end of the extrusion zone; During operation, the first hydraulic rod 4 is controlled to extend, and the extrusion plate 5 is pushed to extrude the plastic material in the extrusion zone. At this time, since the solenoid valve 23 and the inflation head 15 are both in a closed state, the slider 17 cannot move in the air cavity 14, so that the puncture needle 18 will penetrate into the plastic material as the extrusion plate 5 moves, and the puncture needle 18 punctures the plastic material, and the extrusion plate 5 extrude the punctured plastic material. The puncture can not only accelerate the rapid discharge of air in the cavity existing in the plastic material during extrusion, but also avoid the problem that the bottle material in the plastic material cannot discharge its internal air due to its own sealing, resulting in poor extrusion effect; During the process of the puncture needle 18 piercing the plastic material, since the power connection block 19 is in contact with the conductive block 21, the heating rod 20 can be energized to rapidly heat up the puncture needle 18, and the heat can be conducted to rapidly heat up the puncture needle 18, and the plastic material of the puncture needle 18 can be heated to partially melt. The melted plastic liquid can not only reduce the puncture resistance of the puncture needle 18, but also fill the gap inside the compressed material. Moreover, the melted part of the solution contacts the plastic solution near it, and will cool and condense at a position away from the puncture needle 18 or after the puncture needle 18 is separated from the material, so that the extruded plastic materials can be adhered to each other, rather than just being attached together by hard extrusion force, so as to avoid loosening due to factors such as vibration during subsequent transportation, resulting in loosening of the extruded material or even complete dispersion; After the extrusion is completed, the third hydraulic rod 11 is controlled to extend to drive the baffle 12 to move upward, and then the first hydraulic rod 4 is controlled to shorten while opening the solenoid valve 23. At this time, the return spring 16 can drive the slider 17 to move inside the air cavity 14 under its own rebound action, and the air inside the air cavity 14 is blown out from the tapered channel 25 through the guide tube 22 and the annular cavity 24, so as to remove the plastic solution attached to the surface of the puncture needle 18, and avoid the plastic solution from being attached to the surface of the puncture needle 18, resulting in the cooling of the plastic solution in the subsequent working process, resulting in the adhesion of cooling plastic particles to the surface of the puncture needle 18 and affecting the subsequent normal work of the puncture needle 18, and the high-speed airflow during the blowing process will accelerate the cooling of the plastic solution inside the extruded material, ensuring that the extruded material quickly sticks together, and then the first hydraulic rod 4 is controlled to continue to extend, so that the extruded and packaged material can be pushed out for fixed packaging.
