[0027] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0028] The utility model provides a device for automatically removing floating objects from BOPP, comprising:

[0029] An overflow tank is connected to the water tank through the water inlet end of the first drain pipe;

[0030] The first heat exchanger is connected to the bottom of the overflow tank through the water inlet end of the first water return pipe, and the first heat exchanger is connected to the water tank through the second water return pipe;

[0031] A filtration system connected to the overflow tank;

[0032] The control unit is control-connected with the first drain pipe, the first water return pipe and the filtering system.

[0033] Specifically, the device is connected to a water tank, and the overflow tank is connected to the water tank through a first drain pipe, so that floating objects in the water tank can be transferred to the overflow tank for treatment, thereby ensuring the cleanliness of the water tank; in the overflow tank, the floating objects are automatically separated from the water by gravity, so that the water returns to the water tank again through the return pipe and the first heat exchanger, the water sent back to the water tank does not carry floating objects, and the water temperature is reduced through the first heat exchanger, and the floating objects in the overflow tank are sent to the filtering system, the floating objects are filtered, and the filtered water is returned to the overflow tank, and is sent to the return pipe in the overflow tank, thereby reducing the waste of water resources when treating floating objects.

[0034] Optionally, the control unit includes a liquid level meter, which is disposed in the water tank, and a regulating valve connected to the liquid level meter is disposed on the first drain pipe.

[0035] Specifically, a liquid level gauge is provided in the water tank, and the liquid level height of the water tank is monitored by the liquid level gauge. When the liquid level reaches the set first water level control line, the liquid level gauge sends a start signal to the regulating valve, so that the regulating valve is started, and the water and floating objects exceeding the first water level control line are pumped into the overflow tank through the first drain pipe, so as to ensure the liquid level height and the stock of floating objects in the water tank, and prevent the floating objects from gathering in the water tank for a long time, which may easily adhere to the surface of the film and increase the risk of film rupture.

[0036] Optionally, the water inlet end of the first drain pipe is arranged corresponding to the first water level control line of the water tank.

[0037] Optionally, the water outlet end of the second water return pipe is connected to the bottom of the water tank.

[0038] Specifically, a first drain pipe and a second return pipe are provided in the water tank. The first drain pipe is driven by a regulating valve to draw floating objects in the water tank into an overflow tank. In this way, the water inlet end of the first drain pipe is arranged at a position flush with the first water level control line. In this way, the first drain pipe can transfer all floating objects and excess water to the overflow tank, thereby ensuring the process requirements of the water tank. The second return pipe returns the filtered and cooled water to the water tank. In order to prevent the returned water from contacting the floating objects, the second return pipe is connected to the bottom of the water tank.

[0039] Optionally, a first water pump is provided on the first water return pipe.

[0040] Optionally, the filtration system comprises:

[0041] a second water pump connected to the overflow tank through a second drainage pipe;

[0042] a second heat exchanger connected to a second water pump via a filter;

[0043] The temporary storage tank is arranged between the second heat exchanger and the overflow tank, and the temporary storage tank is connected with the overflow tank through the third water pump.

[0044] Specifically, when the water with floating objects in the overflow tank exceeds the second water level control line, the second water pump will be started to send the water and floating objects at the top of the overflow tank to the filter and the second heat exchanger in turn, so that the water body is deoiled and the floating objects are removed, and the heat of the water is transferred to achieve cooling of the water, and the treated water body enters the temporary storage tank; when the liquid level in the overflow tank is lower than the set second water level control line, the third water pump will be started again to send the treated water to the overflow tank, so that the returned water will be retained at the bottom of the overflow tank, so that it is convenient to be pumped back to the water tank by the first return pipe and the first heat exchanger, so that when the floating objects are treated in the filtration system, too much water resources will not be wasted.

[0045] Optionally, the water inlet end of the second drain pipe is arranged corresponding to the second water level control line of the overflow tank.

[0046] Specifically, the water inlet end of the second drain pipe is flush with the second water level control line. When the water level in the overflow tank is higher than the second water level control line, another liquid level gauge arranged in the overflow tank will send a start signal to the second water pump, so that the second water pump will send water with floating objects to the filter and the heat exchanger to process the floating objects; when the liquid level in the overflow tank is lower than the third water level control line, the liquid level gauge will send a start signal to the third water pump, and the third water pump will send the treated water in the temporary storage tank back to the overflow tank, which can not only increase the height of the floating objects and speed up the processing of the floating objects, but also finally send the treated water back to the tank, thereby reducing the waste of water resources.

[0047] Optionally, a filter net is arranged in the filter.

[0048] Optionally, the second heat exchanger is arranged on the circulating water pipeline.

[0049] Optionally, the first heat exchanger is arranged on the circulating water pipeline.

[0050] Specifically, the first heat exchanger and the second heat exchanger are both connected to the circulating water pipeline, so that the water in the filtration system and the return pipe is subjected to heat release treatment, which can effectively reduce the temperature of the water and achieve a cooling effect.
