Description

Technical Field

[0001] This utility model belongs to the field of heat shrink tubing oil heating expansion, specifically relating to a heat shrink tubing oil heating expansion machine with environmentally friendly oil fume treatment function. Background Technology

[0002] A heat shrink tubing expander is a device specifically designed for expanding heat shrink tubing. It uses a specific heating method to bring the heat shrink tubing to a certain temperature, making it highly elastic. Then, it is expanded evenly through an expansion mold and finally rapidly cooled and shaped. This allows for changes in the diameter and length of the heat shrink tubing to meet different application needs.

[0003] In the oil bath heating process of heat shrink tubing production, heating media such as glycerin easily generate oil fumes when heated. If these fumes are not extracted in time, they will significantly impact the production environment and operational efficiency. In traditional production models, the fume extraction device is usually fixed in the center of the oil tank. Due to the obstruction caused by the flow of the medium in the oil tank and the operation of the pipes, the fume extraction path is blocked, often resulting in incomplete extraction. The oil fumes that are not extracted in time will continue to spread into the workshop, not only causing a decline in workshop air quality and a strong odor, but also forming oil stains on equipment surfaces and walls, increasing the workload of workshop cleaning and maintenance. Utility Model Content

[0004] This invention provides a heat shrink tubing oil heating expansion machine with environmentally friendly oil fume treatment function to solve the above-mentioned technical problems.

[0005] The solution adopted by this utility model to achieve its technical effect is as follows:

[0006] An environmentally friendly heat shrink tubing oil heating and expansion machine with fume treatment function includes a base frame, an oil tank, and a fume extraction and oil return mechanism. The oil tank is mounted on the base frame. The fume extraction and oil return mechanism includes a fume extraction trough, a negative pressure pipe, and a return pipe. The fume extraction trough is located on one side of the oil tank, and a ventilation hole is provided between the fume extraction trough and the oil tank. The return pipe is located at the bottom of the fume extraction trough, and its outlet is located above the oil tank. The negative pressure pipe is located on one side of the fume extraction trough and is connected to the fume extraction trough.

[0007] Preferably, the smoke extraction trough is internally connected to a condensation reflux chamber and a negative pressure chamber; the condensation reflux chamber has ventilation holes in its wall; the bottom of the condensation reflux chamber is connected to the reflux pipe; the negative pressure chamber is located above one side of the condensation reflux chamber; and the negative pressure chamber is connected to the negative pressure pipe.

[0008] Preferably, a condensing plate is inclinedly arranged between the negative pressure chamber and the condensation reflux chamber, and the sloping surface of the condensing plate faces the ventilation hole.

[0009] Preferably, the reflux pipe is disposed inside the side wall of the oil tank; the inlet of the reflux pipe is connected to the condensation reflux chamber; and the outlet of the reflux pipe extends above the oil tank.

[0010] Preferably, the smoke extraction and oil return mechanism further includes an oil return tank and a recovery tank; the oil return tank is located at the outlet end of the oil tank; a recovery inlet is provided on the top of the oil return tank; the recovery tank is located on the base frame; and the recovery tank is connected to the recovery inlet.

[0011] Preferably, the outlet of the reflux pipe is located adjacent to and above the recycling inlet.

[0012] Preferably, it further includes an inlet component; the inlet component is disposed on the base frame and is located on one side of the inlet end of the oil tank.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The fume extraction mechanism is installed on the side of the oil tank. When the negative pressure pipe is used in conjunction with the negative pressure device, it can form a more direct and powerful directional exhaust flow. This airflow can quickly cover the core area where oil fumes are generated in the oil tank, efficiently removing the oil fumes. At the same time, it can create a stable negative pressure environment inside the oil tank. The negative pressure state can effectively inhibit the overflow and diffusion of oil fumes into the workshop environment, improve the air quality of the workshop working environment from the source, reduce the pollution of equipment by oil fumes, and reduce the daily cleaning and maintenance costs of the workshop.

[0015] 2. While optimizing the fume extraction efficiency, an oil recovery mechanism has been added. Oil mist drawn away with the airflow during fume extraction is condensed and collected in the condensation return chamber, and then recycled back to the oil tank through the return pipe, achieving the recycling of the heating medium. This design effectively reduces oil loss caused by fume extraction, lowers the frequency of material replenishment and cost input during production, and improves resource utilization efficiency.

[0022] Please refer to Figure 1-4 This utility model discloses a heat shrink tubing oil heating and expansion machine with environmentally friendly oil fume treatment function, including a base frame 1, an oil tank 2, and a smoke extraction and oil return mechanism; the oil tank 2 is disposed on the base frame 1; the smoke extraction and oil return mechanism includes a smoke extraction trough 3, a negative pressure pipe 4, and a return pipe 5; the smoke extraction trough 3 is disposed on one side of the oil tank 2, and a ventilation hole 6 is provided between the smoke extraction trough 3 and the oil tank 2; the return pipe 5 is disposed at the bottom of the smoke extraction trough 3; the outlet of the return pipe 5 is located above the oil tank 2; the negative pressure pipe 4 is disposed on one side of the smoke extraction trough 3; the negative pressure pipe 4 is connected to the smoke extraction trough 3.

A condensing plate 7 is inclinedly arranged between the negative pressure chamber 32 and the condensation reflux chamber 31, with the sloping surface of the condensing plate 7 facing the ventilation holes 6. The extracted fumes are initially cooled by the condensation reflux chamber 31 and then immediately impact the condensing plate 7, where they can quickly condense into oil droplets and then slide down the condensing plate 7, flowing out through the reflux pipe 5 back into the oil trough 2.

Oil fumes with a higher oil content are not easily drawn away directly by the negative pressure pipe and are more likely to recondense into oil droplets and flow back into the oil tank 2.

[0025] Specifically, the smoke extraction and oil return mechanism further includes an oil return tank 8 and a recovery tank 9; the oil return tank 8 is located at the outlet end of the oil tank 2; a recovery inlet 10 is provided on the top of the oil return tank 8; the recovery tank 9 is mounted on the base frame 1; the recovery tank 9 is connected to the recovery inlet 10. Oil in the oil tank 2 that is above the recovery inlet 10 will be recovered and stored in the recovery tank 9.

[0026] Specifically, the outlet of the return pipe 5 is located above the recovery inlet 10, and the recovered oil will preferentially flow into the recovery oil tank 9.

[0027] Specifically, the heat shrink tubing oil heating and expansion machine also includes an inlet assembly 11; the inlet assembly 11 is mounted on the base frame 1 and is located on one side of the inlet end of the oil tank 2. The inlet assembly 11 is used to pull the heat shrink tubing into the oil tank 2.

[0028] Specifically, a cover frame 12 is provided on the side wall of the oil tank 2; the cover frame 12 covers the area above the ventilation hole 6.

[0029] Specifically, the heat shrink tubing oil heating expansion machine also includes a heating mechanism 13 for heating the oil in the oil tank.

[0030] As can be seen from the above description, this utility model not only solves the problem of incomplete fume extraction in traditional solutions, but also realizes oil recovery and reuse. While improving the production environment and reducing labor intensity, it brings significant cost reduction and efficiency improvement value to enterprises.
