Description
Technical Field
[0001] The utility model relates to the technical field of waste recycling devices, in particular to a foam compression device. Background Art
[0002] Foam is widely used in refrigerators. Foam usually contains ozone-depleting substances such as Freon. If it is discarded or handled improperly, it may cause environmental pollution. Therefore, dismantling discarded refrigerators and recycling foam can reduce the negative impact on the environment. By recycling and reprocessing it, it can reduce the production of new materials, thereby saving energy and reducing carbon emissions. Foam has a low density, occupies a large space, and is inconvenient to store and transport. Therefore, when recycling, the foam needs to be compressed and reduced to reduce its volume.
[0003] In the prior art, foam may "explode" when being compressed. This is because there is a large amount of air in the foam. If the air is not discharged smoothly during compression, the internal gas pressure will increase, causing a large amount of foam fragments to be ejected from the compressor and scattered in the surrounding environment, and causing the subsequent section of foam to be unable to be compressed and compacted. When encountering this situation, the staff will control the machine to stop working immediately, and then restart the machine to compress again, which affects the continuous compression and reduces work efficiency. Utility Model Content
[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides a foam compression device, which solves the problem in the prior art that the compression is affected by the spontaneous explosion of the foam.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A foam compression device is provided, which comprises a feed hopper, a shredding module for shredding foam, a conveying module for conveying foam fragments, and a compression module for compressing foam, which are connected in sequence; the shredding module and the conveying module are both electrically connected to a controller;
[0007] A limiting device is arranged at the outlet of the compression module, and the limiting device comprises a limiting plate, the size of the limiting plate is larger than the outlet cross-sectional size of the compression module, and the limiting plate is slidably connected to the side wall of the outlet end of the compression module.
[0008] The beneficial effect of the utility model is that when the staff hears the foam "exploding" and spraying out, they can slide the limit plate down in time to block the outlet of the compression module. At this time, the foam is blocked by the limit plate, and the conveying module continues to normally convey the foam fragments into the compression module. The foam fragments that were originally loose in the compression module will be compressed and compacted under the combined action of this continuous thrust and the resistance of the limit plate to form a normal-shaped compression block. After working in this way for a period of time, the gas is discharged, and the operation of the machine will gradually return to normal. The staff will slide the limit plate down again so that it no longer blocks the outlet of the compression module, so there is no need to shut down the machine to interrupt work, and the device can continue to operate normally.
[0009] Furthermore, the limiting device also includes a hydraulic cylinder, and the upper part of the limiting plate is fixedly connected to the end of the piston rod of the hydraulic cylinder; a sound sensor is installed on one side of the compression module; and the hydraulic cylinder and the sound sensor are both electrically connected to the controller. This solution can monitor whether the foam has "self-exploded" through the sound sensor, and when "self-exploded" occurs, the controller opens the hydraulic cylinder with the limiting plate to close the outlet of the compression module, so that the foam in the compression module can be compressed and compacted in time, and the whole process does not require human intervention.
[0010] Furthermore, it also includes a discharge cavity connected to the outlet end of the compression module, and a gap with a width greater than the thickness of the limiting plate is provided between the outlet end of the compression module and the inlet end of the discharge cavity. The gap is greater than the thickness of the limiting plate to accommodate the limiting plate extending into the gap, thereby blocking the outlet of the compression module.
[0011] Furthermore, a guide rail is provided on the side wall of the outlet end of the compression module, and a slide rail that slides with the guide rail is fixedly connected to the corresponding position of the limit plate. The guide rail and the slide rail are provided to make the sliding smooth and labor-saving, and secondly, to enable the limit plate to be connected with the compression module when closed, thereby increasing the anti-thrust ability of the limit plate and reducing the deformation of the limit plate when it is subjected to thrust.
[0012] Furthermore, a feeding plate is provided at the bottom of the compression module, and the feeding plate extends to the outside of the outlet end of the discharge cavity; the feeding plate is fixedly connected to the inner wall of the bottom plate of the discharge cavity. Since there is a gap between the compression module and the discharge cavity, the feeding plate can connect the two, and the compressed finished material can move along the feeding plate to ensure smooth discharge and not get stuck at the gap due to accidents.
[0013] Furthermore, a bracket is provided on one side of the compression module, and the hydraulic cylinder is fixed on the bracket.
[0014] Furthermore, the shredding module includes at least two shredding shafts, and a plurality of blades are fixedly connected along the axial direction of the shredding shafts; the shredding shafts are connected to a motor, and the motor is electrically connected to a controller; the rotation directions of two adjacent shredding shafts are opposite, and the blades thereon are staggered. The motor drives the shredding shafts to rotate, and when the two adjacent shredding shafts move toward each other, the staggered blades thereon can shred the entire piece of foam, and the shredding shafts can be automatically controlled by the controller.
[0015] Furthermore, the conveying module is located below the shredding module; the conveying module includes a spiral shaft connected to a motor; the motor is electrically connected to the controller. The shredded foam can fall freely to the conveying module due to gravity, and then be spirally pushed to the compression module by the spiral shaft of the conveying module.
[0016] Furthermore, a compression channel is provided inside the compression module, and the cross-sectional area of the compression channel gradually decreases from the inlet end to the outlet end. The foam is pushed by the conveying module and squeezed by the compression channel at the same time, and the volume of the foam is reduced and the density is increased under the combined action of thrust and pressure, so that it is compressed into a finished product.

DETAILED DESCRIPTION
[0020] The specific implementation methods of the utility model are described below to facilitate technical personnel in this technical field to understand the utility model, but it should be clear that the utility model is not limited to the scope of the specific implementation methods. For ordinary technical personnel in this technical field, as long as various changes are within the spirit and scope of the utility model defined and determined by the attached claims, these changes are obvious, and all utility model creations using the concept of the utility model are protected.
[0021] like Figure 1 As shown, the foam compression device of the present embodiment includes a feed hopper 10, a shredding module 20 for shredding foam, a conveying module 30 for conveying foam fragments, a compression module 40 for compressing foam, and a discharge chamber 50, which are connected in sequence; the shredding module 20 and the conveying module 30 are both electrically connected to the controller.
[0022] The shredding module 20 includes at least two shredding shafts 21, and a plurality of blades are fixedly connected along the axial direction of the shredding shafts 21; the shredding shafts 21 are connected to a motor, and the motor is electrically connected to a controller; the rotation directions of two adjacent shredding shafts 21 are opposite, and the blades thereon are staggered. The motor drives the shredding shafts 21 to rotate, and when the two adjacent shredding shafts 21 move toward each other, the staggered blades thereon can shred the entire piece of foam, and the shredding shafts 21 can be automatically controlled by the controller. The shredding shafts 21 can be two or four, two in a group, and the shredding shafts 21 in the same group rotate toward each other.
[0023] During implementation, the conveying module 30 is preferably located below the shredding module 20; the conveying module 30 includes a spiral shaft 31 connected to a motor 32; the motor 32 is electrically connected to the controller. The shredded foam can fall freely to the conveying module 30 due to gravity, and then be spirally pushed to the compression module 40 by the spiral shaft 31 of the conveying module 30. The motor 32 can drive the spiral shaft 31 to rotate, so that the foam fragments move forward along the spiral sheet on the spiral shaft 31. The motor 32 is connected to the controller to realize automatic control.
[0024] In one embodiment of the present invention, a compression channel is provided inside the compression module 40, and the cross-sectional area of the compression channel gradually decreases from the inlet end to the outlet end. The foam is pushed by the conveying module 30 and squeezed by the compression channel at the same time, and the volume of the foam is reduced and the density is increased under the combined action of the thrust and pressure, so that the foam is compressed into a finished product.
[0025] refer to Figure 2 A limiting device 60 is provided between the compression module 40 and the discharge chamber 50, and the limiting device 60 includes a limiting plate 63, the size of the limiting plate 63 is larger than the outlet cross-sectional size of the compression module 40, and the limiting plate 63 is slidably connected to the side wall of the outlet end of the compression module 40. The limiting device 60 also includes a hydraulic cylinder 61, and the upper part of the limiting plate 63 is fixedly connected to the end of the piston rod 62 of the hydraulic cylinder 61; a sound sensor is installed on one side of the compression module 40; the hydraulic cylinder 61 and the sound sensor are both electrically connected to the controller. The sound sensor can be used to monitor whether the foam "explodes" and when the "explosion" occurs, the outlet of the compression module 40 is closed by the controller, so that the foam in the compression module 40 is compressed and compacted in time, and automatic remote control is realized, and the whole process does not require human participation. The sound sensor can be the Yiou Speed Noise Sensor RS485 in the prior art, and the controller can be a PLC controller.
[0026] In this solution, a notch 70 with a width greater than the thickness of the limiting plate 63 is preferably provided between the outlet end of the compression module 40 and the inlet end of the discharge chamber 50. The notch 70 is greater than the thickness of the limiting plate 63 to accommodate the limiting plate 63 extending into the notch 70, thereby blocking the outlet of the compression module 40. A feed plate 42 is provided at the bottom of the compression module 40, and the feed plate 42 extends to the outside of the outlet end of the discharge chamber 50; the feed plate 42 is fixedly connected to the inner wall of the bottom plate of the discharge chamber 50. Since there is a notch 70 between the compression module 40 and the discharge chamber 50, the feed plate 42 is provided to connect the two, and the compressed finished material can move along the feed plate 42, ensuring smooth discharge and not being stuck at the notch 70 due to accidents.
[0027] A guide rail 41 is provided on the side wall of the outlet end of the compression module 40, and a slide rail 65 that slides with the guide rail 41 is fixedly connected to the corresponding position of the limit plate 63. The guide rail 41 and the slide rail 65 are provided to make the sliding smooth and labor-saving, and secondly, to enable the limit plate 63 to be connected with the compression module 40 when closed, thereby increasing the anti-thrust ability of the limit plate 63 and reducing the deformation amount generated when the limit plate 63 is subjected to thrust. The guide rail 41 and the slide rail 65 can adopt the drawer slide rail in the prior art, and the guide rail and the slide rail can only be pulled and are not easy to separate. In addition, the design of the notch 70 can also help the limit plate 63 resist its deformation in the X-axis direction. A bracket 64 is provided on one side of the compression module 40, and the hydraulic cylinder 61 is fixed on the bracket 64.
[0028] The working principle of the utility model is as follows: when the foam "explodes" and sprays out, the sound sensor detects that the decibel is greater than the set value, and sends a signal to the controller, so that the controller turns on the hydraulic cylinder 61, and the piston rod 62 drives the limit plate 63 to slide down in time to block the outlet of the compression module 40. At this time, the foam is blocked by the limit plate 63, and the conveying module 30 still normally continues to convey the foam fragments into the compression module 40. The foam fragments that were originally loose in the compression module 40 will continue to be compressed and compacted under the combined action of this continuous thrust and the resistance of the limit plate 63 to form a normal compressed block. After a certain set time, the gas is discharged, and the machine operation will gradually return to normal. The controller then controls the hydraulic cylinder 61 to drive the limit plate 63 to slide up so that it no longer blocks the outlet of the compression module 40. Therefore, there is no need to shut down the machine to interrupt work, and the compression device can continue to operate normally.
[0029] In summary, the limiting device 60 in the present solution can block the outlet of the compression module 40, so that the loose foam after self-explosion continues to be compressed in the compression module 40, which can avoid shutdown and enable the compression device to continue working.
