Description

Technical Field

[0001] The utility model belongs to the technical field of cable production, in particular to an outdoor lubricating oil cooling pool for cable production. Background Art

[0002] The first step in cable production is wire drawing, where aluminum rods are drawn into single filaments. These filaments are then twisted through multiple stranding processes on a stranding machine to form wire and cable. Wire drawing equipment then passes the aluminum rods through one or more drawing dies, reducing their cross-sectional area, increasing their length, and improving their strength. The process of drawing aluminum rods into single wires requires lubrication. During this process, the aluminum rods interact with the dies within the high-speed wire drawing machine, generating a certain amount of heat. The greater the friction and compression during this interaction, the greater the heat generated. Therefore, lubricating oil not only lubricates but also absorbs heat. Therefore, the rods must be lubricated during the drawing process, and the oil temperature must be controlled.

[0003] Hot lubricating oil needs to be transported to a cooling device for cooling before being re-circulated for use in the wire drawing process. During use, the lubricating oil dissolves aluminum powder generated during aluminum rod drawing. This aluminum powder accumulates in the recycled lubricating oil, potentially clogging the delivery pipeline and impacting cable production. Therefore, it is necessary to design an outdoor lubricating oil cooling tank for cable production that can separate and remove aluminum powder from the lubricating oil. Utility Model Content

[0004] In response to the above technical problems, the utility model provides an outdoor lubricating oil cooling pool for cable production that can separate and remove aluminum powder mixed in lubricating oil, so as to solve the problem that aluminum powder in lubricating oil is excessively deposited in the conveying pipeline and blocks the conveying pipeline, thereby affecting cable production.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: an outdoor lubricating oil cooling pool for cable production, comprising a cooling pool, wherein a vertically arranged overflow plate is fixedly connected in the middle of the cooling pool, and the overflow plate divides the cooling pool into a sedimentation area and a heat exchange area, the upper side of the side wall of the sedimentation area is fixedly connected to a hot oil inlet, and the lower side of the side wall is fixedly connected to a waste oil discharge port, the bottom of the sedimentation area is fixedly connected to an inclined block, and the bottom of the sedimentation area is provided with a sewage outlet on the side of the inclined block inclined downward, and the sewage outlet is connected to the sewage suction pump, a heat exchange tube group is arranged in the heat exchange area, a turbine is arranged at the lower side of the interior of the heat exchange area, a first motor is fixedly connected to the lower side of the exterior of the heat exchange area, the output end of the first motor extends through the interior of the heat exchange area and is fixedly connected to the rotating shaft of the turbine, the lower side of the heat exchange area is fixedly connected to a lubricating oil outlet, and valves are installed on the hot oil inlet, the waste oil discharge port and the lubricating oil outlet.

[0006] Furthermore, a cleaning mechanism is provided above the tilting block, and the cleaning mechanism includes a second motor, two groups of chain transmission groups and several brush plates, each group of the chain transmission groups includes a chain and two sprockets, and the chains and sprockets in the same group are meshed and transmitted. The opposite sides of the two groups of chains are fixedly connected to one end of the brush plate through connecting members, and the side wall of the sedimentation area is rotatably connected to two rotating rods, and the axis of each sprocket is fixedly connected to one side of the rotating rod, one end of one of the rotating rods extends out of the sedimentation area and is fixedly connected to the output end of the second motor, and the second motor is fixedly connected to the outer wall of the cooling pool.

[0007] Furthermore, the heat exchange tube group is composed of at least three groups of heat exchange tubes, the heat exchange tubes are fixedly connected to the side wall of the heat exchange area, the input end of the heat exchange tube is connected to the refrigerant supply pipe, and the output end of the heat exchange tube is connected to the refrigerant return pipe, and the refrigerant supply pipe and the refrigerant return pipe are both connected to the condenser.

[0008] Furthermore, a cover plate is hinged on one side of the upper end of the cooling pool.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] 1. The utility model divides the cooling pool into a sedimentation zone and a heat exchange zone by arranging an overflow plate. After the hot oil is discharged from the workshop, it first enters the sedimentation zone under the obstruction of the overflow plate. The heavier aluminum powder in the hot oil gradually sinks to the lower part of the sedimentation zone, and the upper hot oil without aluminum powder flows into the heat exchange zone from above the overflow plate, thereby realizing the separation of aluminum powder in the lubricating oil and preventing the aluminum powder from re-entering the lubricating oil delivery pipeline and depositing and clogging the pipeline. A sewage outlet is opened below the sedimentation zone and connected to a sewage suction pump, which is convenient for cleaning the aluminum powder deposited at the bottom of the sedimentation zone and improves the cleaning efficiency. A turbine is arranged below the heat exchange zone to stir the hot oil entering the heat exchange zone and accelerate the cooling rate of the hot oil.

[0011] 2. The utility model sets a cleaning mechanism in the sedimentation area, which can clean the aluminum powder deposited at the bottom of the sedimentation tank and brush the inclined surface of the top of the inclined block at the same time, thereby further improving the cleaning efficiency. By hingedly connecting a cover plate above the cooling pool, it can effectively prevent dust, impurities and water droplets from falling into the cooling pool during rainy and snowy weather, thereby avoiding contamination of the lubricating oil in the cooling pool.

A heat exchange tube group is provided in the heat exchange area 4. A turbine 10 is provided on the lower side of the interior of the heat exchange area 4. A first motor 11 is fixedly connected to the lower side of the exterior of the heat exchange area 4. The output end of the first motor 11 extends into the interior of the heat exchange area 4 and is fixedly connected to the rotating shaft of the turbine 10. The output end of the first motor 11 is rotatably connected to the bottom wall of the heat exchange area 4 and a shaft seal is provided at the connection. A lubricating oil outlet 12 is fixedly connected to the lower side of the heat exchange area 4. The lubricating oil outlet 12 is pumped to the oil supply pipeline of the workshop through an oil pump. Valves are installed on the hot oil inlet 5, the waste oil discharge port 6 and the lubricating oil outlet 12.

[0018] In order to facilitate the timely cleaning of the top inclined surface of the inclined block 7 when cleaning the accumulated aluminum powder deposits, a cleaning mechanism is provided above the inclined block 7, and the cleaning mechanism includes a second motor 13, two groups of chain transmission groups and several brush plates 16. Each group of chain transmission groups includes a chain 14 and two sprockets 15. The chains 14 and sprockets 15 of the same group are meshed and driven. The opposite sides of the two groups of chains 14 are fixedly connected to one end of the brush plate 16 by connecting members. The side wall of the sedimentation area 3 is rotatably connected to two rotating rods 17, and the axis of each sprocket 15 is fixedly connected to one side of the rotating rod 17. One end of one rotating rod 17 extends outside the sedimentation area 3 and is fixedly connected to the output end of the second motor 13.

[0021] The specific working process of this utility model is as follows:

[0022] The hot oil used in the workshop enters the sedimentation area 3 through the hot oil inlet 5. The fluidity of the hot oil is reduced under the obstruction of the overflow plate 2. The aluminum powder in the hot oil continues to settle downward in the sedimentation area 3, and the hot oil without aluminum powder in the upper layer of the sedimentation area 3 passes above the overflow plate 2 and enters the heat exchange area 4, and exchanges heat and cools down with the three groups of heat exchange tubes 18 arranged in the heat exchange area 4. The hot oil is continuously stirred under the rotation of the turbine 10 driven by the first motor 11, which accelerates the heat exchange speed with the heat exchange tube 18. Finally, the cooled lubricating oil enters the oil pump through the lubricating oil outlet 12 and is pumped to the oil supply pipeline of the workshop and enters the workshop for use again.

[0023] When regularly cleaning the aluminum powder deposited in the sedimentation area 3, first close the valves on the hot oil inlet 5 and the lubricating oil outlet 12, then open the valve on the waste oil discharge port 6, and discharge the waste oil in the sedimentation area 3 into the waste pool, open the valve on the input end of the sewage suction pump 9, start the sewage suction pump 9, suck out the deposited aluminum powder slurry, and then start the second motor 13. The second motor 13 drives the rotating rod 17 to rotate, drives the sprocket 15 fixedly connected to the rotating rod 17 to rotate, thereby driving the chain 14 and the brush plate 16 fixedly connected to the chain 14 to move, and brushing and cleaning the top inclined surface of the inclined plate 7 that contacts the brush part.
