[0020] like Figure 1 As shown, a waste oil recovery pipeline device for a drawing machine drawing box includes a plurality of oil receiving pans 7, a recovery device 8 for centrally collecting the oil in each of the oil receiving pans 7, the recovery device 8 includes a waste oil barrel 12, a sealing cover 11 arranged on the waste oil barrel 12, a PVC pipe 2 connected to the sealing cover 11 at one end, and an Asia-Pacific pipe 5 arranged between the PVC pipe 2 and each of the oil receiving pans 7, each of the oil receiving pans 7 is provided with an oil dripping hole 6 at the bottom, one end of the Asia-Pacific pipe 5 is arranged on the oil dripping hole 6, a PVC elbow 3 is provided at one end of the PVC pipe 2, and a plurality of three-way pipe joints 1 are also provided on the PVC pipe 2, the oil outlet of the Asia-Pacific pipe 5 is connected to the PVC pipe 2 through the PVC elbow 3 or the three-way pipe joint 1, the oil in the oil receiving pan 7 flows downward through the Asia-Pacific pipe 5 to the PVC pipe 2 for circulation, and then centrally flows back to the waste oil barrel 12 for collection.

[0021] During the actual assembly process, all the current oil receiving trays 7 are uniformly replaced with a structure with an oil drip hole 6 at the bottom, and then one end of the Asia-Pacific pipe 5 of appropriate length is connected to the oil drip hole 6 of each oil receiving tray 7. Among them, each section of the machine has 4 wire drawing boxes, and there are 4 Asia-Pacific pipes 5. The oil outlets of the Asia-Pacific pipes 5 are basically aligned and fixed with nylon tie bands. A 1.5-inch PVC pipe 2 is installed on the drawing machine dragon frame, and a 1.5-inch PVC elbow 3 is installed at one end of the first pipe, and the elbow is required to face upward, and a 1.5-inch PVC three-way pipe joint 1 is installed at the other end. They are connected with 1.5-inch PVC three-way pipe joints 1 in turn, and the three-way pipe joints 1 are required to face upward, for a total of 14 sections. Then the four Asia-Pacific pipes 5 fixed together are inserted into the upward PVC elbow 3 or the three-way pipe joint 1. It is required not to be inserted too deep, as too deep will prevent the fluidity of the waste oil, and too shallow will prevent To prevent the three-way pipe joint 1 from falling off and the waste oil from flowing into the ditch, a sealing cover 11 is installed at the outlet of the PVC pipe 2 at the rear of the machine, and a waste oil barrel 12 is installed at the bottom of the sealing cover 11. When the waste oil falls into each oil receiving tray 7, the waste oil can flow into the PVC pipe 2 along the Asia-Pacific pipe 5, and then flow into the waste oil barrel 12 at the bottom of the sealing cover 11 through the PVC pipe 2 for unified collection. When the waste oil barrel 12 is full, the waste oil barrel 12 can be replaced for treatment, thereby effectively solving the problems of serious oil overflow in the existing oil receiving tray 7 due to blockage of the oil return hole or oil leakage in the wire drawing box, poor machine hygiene, heavy oil in the machine ditch, and difficult management of the on-site environment, so that the final product will not be degraded due to oil contamination, which is simpler and more convenient for workshop on-site management and product quality management.

[0022] Further improvement is as follows: Figure 2 As shown, the sealing cover 11 is also provided with an upwardly protruding air suction interface 9, and a detachable air suction device 10 is also provided outside the air suction interface 9. The air in the waste oil barrel 12 is extracted through the air suction device 10 to form a negative pressure, and the blocked Asia-Pacific pipe 5 or the oil dripping hole 6 can be evacuated and unblocked through the air suction device 10.

[0023] Since waste oil can easily clog the Asia-Pacific pipe 5 or the oil drip hole 6 during long-term diversion, and it is inconvenient to stop the machine for processing after a problem is found during operation, in order to solve the problem that the oil circuit is blocked and cannot be unblocked immediately, an outwardly protruding air suction interface 9 is installed on the sealing cover 11. When the oil circuit needs to be unblocked, the air suction pipe of the air suction device 10 is inserted into the air suction interface 9, and then the air suction device 10 is started to suck air, so that the waste oil barrel 12 sealed by the sealing cover 11 can be cleaned. It is possible to form a negative pressure, so that the negative pressure in the waste oil barrel 12 generates suction on the entire oil circuit, so that the blocked Asia-Pacific pipe 5 or the oil drip hole 6 can be initially unblocked, and further cleaning can be performed after the equipment is shut down. When the oil circuit is unblocked, the air extraction device 10 can be disassembled from the air extraction interface 9, and the combination flexibility of the air extraction device 10 is higher, especially the oil inlet of the air extraction interface 9 and the sealing cover 11 are not a hole, and the oil will not be directly sucked into the air extraction device 10 during air extraction, thereby not shortening the life of the air extraction device 10. Generally, the air extraction device 10 can be replaced by existing small equipment such as an air pump and a fan, which is more flexible. A bellows is provided between the sealing cover 11 and the discharge port of the PVC pipe 2. The sealing cover 11 and the waste oil barrel 12 are connected by threads. When the waste oil barrel 12 needs to be replaced, it can be quickly separated. In addition, there will be no overflow or overturning problems during the oil collection process. In particular, the bellows connection can be freely adjusted according to the height of the waste oil barrel 12, which has higher flexibility. The connection between the sealing cover 11 and the bellows can be connected by a bearing, and a pipe is sleeved in the bearing. Only one end of the bellows needs to be fixed to the end of the pipe. When the sealing cover 11 is rotated, the sealing cover 11 can be freely rotated without the bellows moving.

[0024] Further improvement is as follows: Figure 3 As shown, the PVC elbow 3 and the three-way pipe joint 1 are each provided with a dust cover 4, and the dust cover 4 is provided with a plurality of outwardly protruding conical joints 13, and the lower end of the Asia-Pacific pipe 5 is connected through the conical joint 13; the dust cover 4 is threadedly connected to the PVC elbow 3 and the three-way pipe joint 1.

[0025] In order to prevent the Asia-Pacific tube 5 from falling during use and to avoid a large amount of gas in the oil circuit from being discharged outward, the open ends of the PVC elbow 3 and the three-way pipe joint 1 are blocked by the dust cover 4, so as to effectively prevent the gas from flowing out. During cleaning, the oil pan 7 can be directly connected for comprehensive cleaning. After the sewage flows into the PVC pipe 2 through the Asia-Pacific tube 5, the sewage will not overflow from the open ends of the PVC elbow 3 and the three-way pipe joint 1. At the same time, each dust cover 4 is provided with a number of upwardly protruding conical joints 13, which can facilitate the direct insertion of the Asia-Pacific tube 5 and avoid the problem of the Asia-Pacific tube 5 being inserted into the PVC pipe 2 too deep or too shallow. Generally, there are 4 conical joints 13 on the dust cover 4, which can just correspond to the number of wire drawing boxes in each section of the machine, and the dust cover 4 is threadedly connected to the PVC elbow 3 and the three-way pipe joint 1, and can be replaced according to the number of different wire drawing boxes, thereby making it more flexible.

[0026] A further improvement is that the bottom of the oil receiving pan 7 is an arc-shaped or inclined surface structure, and one end of the oil drip hole 6 is located at the lowest point of the bottom of the oil receiving pan 7; the PVC pipe 2 is arranged in an inclined structure of 5 to 10 degrees, and one end of the PVC pipe 2 is connected to the sealing cover 11 through a corrugated pipe.

[0027] The bottom of the oil receiving pan 7 is an arc-shaped or inclined surface structure, and one end of the oil drip hole 6 is located at the lowest point of the bottom of the oil receiving pan 7, which can make the waste oil liquid flow better and avoid the problem of oil accumulation. At the same time, when the oil flows into the PVC pipe 2, it can prevent the oil from accumulating in the PVC pipe 2.

[0028] The above-mentioned implementation modes are only preferred implementation modes of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present application shall fall within the scope of protection required by the present application.
