Description

Technical Field

[0001] This invention relates to the field of crushing equipment technology, specifically to a crushing device for the production of nylon products. Background Technology

[0002] Waste fishing nets are woven from nylon 6. Recycling waste fishing nets is an environmentally friendly way to produce nylon products. For example, Chinese patent CN101805516B discloses the preparation of nylon 6 chips using waste fishing nets and its preparation method. It describes that: the recycled waste fishing nets are broken into fragments with a diameter of less than 10mm, the fragments are washed to remove mud and sand, centrifuged and dried until the moisture content is less than 0.2%.

[0003] As can be seen from the patents mentioned above, in the prior art, when recycling nylon waste fishing nets, they are usually crushed first and then washed. This method accelerates the wear of the crushing blades because the fishing nets contain mud and sand, and the fishing nets are easily tangled on the surface of the blade shafts, affecting the crushing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a crushing device for the production of nylon products, so as to solve the problems mentioned in the background art.

[0010] The secondary cross-cutting mechanism includes a cylinder wall support ring, a bottom screen plate, a corrugated connecting ring, screen holes, a central motor, and an eccentric blade. The cylinder wall support ring is fixedly installed on the inner wall surface of the crushing main cylinder, and the bottom screen plate is located below the cylinder wall support ring. A corrugated connecting ring is provided between the cylinder wall support ring and the bottom screen plate.

[0012] The dry and wet separation chamber is equipped with a water filter baffle inside. A partition support plate is fixedly installed on the lower surface of the dry and wet separation chamber.

A flat water spray nozzle is opened inside the transverse water tank. The flushing water inlet pipe is connected to the transverse water tank.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention relates to a crushing device suitable for the recycling and processing of nylon waste fishing nets. Through the design of structures such as a sand-washing inclined pipe, the waste fishing nets can be continuously washed first to remove mud and sand before crushing. Compared with the existing processing technology of crushing first and then washing, this method can reduce the wear of mud and sand on the crushing cutting edge and improve the service life of the crushing cutting edge. Through the cooperation of the sewage pipe, the flushing water inlet pipe and the ultrasonic transducer, efficient continuous flushing can be achieved. Furthermore, in conjunction with the main crushing cylinder, automatic feeding can be achieved, which can significantly improve work efficiency.

[0017] The specially designed crushing mechanism can vertically separate the fishing nets wrapped around the vertical shaft surface of the blades by raising and lowering the vertical cutting blades. This has anti-tangling capabilities and improves the stability of crushing. At the same time, high-pressure airflow can be ejected from the vertical cutting groove and the air jet shaft hole. The airflow can quickly disperse the vertically separated fishing nets and prevent them from piling up. Furthermore, the airflow ejected from the vertical cutting groove and the air jet shaft hole gradually connects from bottom to top as the piston lifting cap moves upward, which can promote the upward tumbling of the fishing nets inside the crushing main cylinder, allowing them to fully contact the crushing cutting blades and improve the uniformity and efficiency of crushing. The airflow ejected from the vertical cutting groove and the air jet shaft hole will create positive pressure inside the crushing main cylinder, which can increase the rate at which the crushed fishing nets pass through the screen holes.

[0018] The secondary cross-cutting mechanism can perform a secondary cross-cutting on fishing nets that pass vertically through the screen holes, reducing the large amount of breakage and leakage that occurs when long fishing nets pass vertically through the screen holes. At the same time, the eccentric blades are set eccentrically, which can drive the bottom screen plate to swing, further improving the screening efficiency.

[0019] The dry-wet separation chamber has drying and separation functions. Hot air is introduced through the hot air inlet pipe to dry the broken fishing nets on the upper surface of the filter baffle. The dried fishing nets are in a loose state and can be sprayed out from the dry net outlet pipe with the airflow, thus achieving dry-wet separation. The movable baffle is in a lifting and lowering state. When the movable baffle is lowered and closed, all the hot air introduced through the hot air inlet pipe is sprayed out through the dry net outlet pipe, which can accelerate the drying and separation efficiency. When the movable baffle is raised and opened, the vibration of the filter baffle can cause the wet fishing nets below the crushing main cylinder to be shaken and spread out to the top of the hot air inlet pipe for replenishment. At the same time, the hot air diverted into the crushing main cylinder can reverse the flow of air through the screen holes to keep them unobstructed. Attached Figure Description

An eccentric blade 718 is installed below the bottom screen plate 714. The eccentric blade 718 is in contact with the lower surface of the bottom screen plate 714. The central motor 717 is connected to the eccentric blade 718 for transmission.

[0039] The dry and wet separation chamber 8 is equipped with a water filter baffle 801 inside. A partition support plate 802 is fixedly installed on the lower surface of the dry and wet separation chamber 8. The water filter baffle 801 is pressed on the upper surface of the partition support plate 802. A vibration chamber 803 is fixedly installed on the lower surface of the water filter baffle 801. A drain bottom pipe 804 is connected to the bottom of the dry and wet separation chamber 8.

[0040] The upper surface of the wet-dry separation chamber 8 has a top slot 805, and a movable partition 806 is inserted inside the top slot 805. The movable partition 806 corresponds to the partition support plate 802 vertically. A hanger plate 807 is fixedly installed on the upper surface of the wet-dry separation chamber 8. A lifting drive cylinder 808 is installed on the surface of the hanger plate 807. A shaft end plate 809 is fixedly installed at the end of the telescopic shaft of the lifting drive cylinder 808. The shaft end plate 809 is fixedly installed with the movable partition 806. A hot air input pipe 810 is connected to the bottom of the wet-dry separation chamber 8. The hot air input pipe 810 is located on the side of the partition support plate 802 away from the crushing main cylinder 7. A dry screen outlet pipe 811 is connected to the upper surface of the wet-dry separation chamber 8. The dry screen outlet pipe 811 corresponds to the hot air input pipe 810.

[0041] The upper surface of the sand-washing incline 1 is provided with a fishing net feeding port 101. A hammer frame plate 102 is fixedly installed on the inner wall surface of the sand-washing incline 1. A hammer box 103 is fixedly installed on the lower surface of the hammer frame plate 102. The hammer box 103 is located in the inner ring of the transfer track 2. The hammer box 103 corresponds to the upper part of the crushing main cylinder 7. The hammer box 103 can drive the transfer track 2 to locally impact and vibrate. The hammer box 103 is composed of electromagnets and springs, etc., which can impact and strike the transfer track 2, causing the transfer track 2 to shake, which facilitates the separation of the fishing net from the fishing net needle 3. A track shaft 201 is rotatably installed inside the sand-washing incline 1. The transfer track 2 covers the outside of the track shaft 201. A transverse water tank 501 is fixedly installed on the lower surface of the sand-washing incline 1. A flat water spray nozzle 502 is opened inside the transverse water tank 501. The flushing water inlet pipe 5 is connected to the transverse water tank 501.

[0042] When in use, the external pressure water source enters through the flushing inlet pipe 5 and is discharged from the drain pipe 4, maintaining the water level inside the sand washing pipe 1 above the ultrasonic transducer 6 and below the flat spray nozzle 502. The impact air branch pipe 706 is connected to the external controllable high-pressure air source, and the hot air input pipe 810 is connected to the external dry hot air.

[0043] Waste fishing nets are fed into the net inlet 101, and the track 2 is attached to them. Figure 4As shown, the net rotates counterclockwise. The net is inserted into the holes of the net through the net pin 3, causing the net to rotate counterclockwise. The ultrasonic transducer 6 emits cleaning ultrasonic waves. When the net reaches the position of the ultrasonic transducer 6, it is quickly cleaned to remove mud and sand. The mud and sand settle to the bottom and are discharged through the drain pipe 4. After the net moves to the position of the flat spray nozzle 502, it is further rinsed clean. Driven by the net pin 3, the net moves to the upper part of the crushing main cylinder 7. Under the impact of the hammer box 103, the hanging track 2 shakes locally, and the net is put into the interior of the crushing main cylinder 7.

[0044] The crushing blade 707 rotates to crush and cut the fishing net. The impact air branch pipe 706 is connected to an external controllable high-pressure air source, and intermittent high-pressure airflow is introduced into the impact air branch pipe 706. The high-pressure airflow enters the interior of the blade vertical shaft 703 through the shaft base 704, driving the piston lifting cap 710 to move upward rapidly. At this time, the vertical cutting blade 711 moves upward rapidly in the vertical chopping groove 708, cutting the fishing net wrapped around the surface of the blade vertical shaft 703. As the piston lifting cap 710 moves upward, the vertical chopping groove 708 and the jet shaft hole 709 located at the lower part of the piston lifting cap 710 are connected to the high-pressure airflow, and the gas is ejected. The airflow can quickly blow away the vertically cut fishing net. As the connection is gradually made from bottom to top, it can promote the upward tumbling of the fishing net inside the crushing main cylinder 7, so that it can fully contact the crushing blade 707. When the airflow stops, the piston lifting cap 710 moves downward and resets under the elastic force of the reset spring 712, and cuts again.

[0045] The broken fishing net is discharged after being screened through the sieve hole 716. The longer fishing net that passes vertically through the sieve hole 716 is cut horizontally a second time by the rotation of the eccentric blade 718. The eccentric blade 718 is set eccentrically, which can drive the bottom sieve plate 714 to swing, further improving the screening efficiency.

[0046] Damp, broken fishing nets accumulate on the surface of the filter baffle 801. At this time, the vibrating chamber 803 drives the filter baffle 801 to shake, which can accelerate the dripping of accumulated water and discharge it from the bottom drain pipe 804. At the same time, the shaking can also spread the damp, broken fishing nets on the upper surface of the filter baffle 801. The lifting drive cylinder 808 drives the movable baffle 806 to move up and down, so that the movable baffle 806 can open and close. When the movable baffle 806 is lowered and closed, all the hot air input by the hot air input pipe 810 is sprayed out through the dry net extrusion pipe 811, which can accelerate the drying and separation efficiency. When the movable baffle 806 is raised and opened, the vibration of the filter baffle 801 can cause the damp fishing nets below the crushing main cylinder 7 to be shaken and spread out above the hot air input pipe 810 for replenishment. At the same time, the hot air diverted into the crushing main cylinder 7 can reverse the flow of air through the screen holes 716 to keep the screen holes 716 unobstructed.
