Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, and more specifically to a laminated vacuum pump oil circulation filtering system used for processing solar energy components. Background Art

[0002] Laminator refers to mechanical equipment that presses multiple layers of materials together. It is also an important equipment required for the manufacture of solar cell modules. It is a device that presses EVA film, solar cell sheets, tempered glass, and back film into a rigid whole under high temperature and vacuum conditions. After the EVA film has been subjected to high temperature in the laminator, the peroxide, antioxidant, and trace wax acid added to the EVA film will escape back as the temperature rises. Part of these complex substances are sucked into the vacuum pump, adsorbed on the various components in the vacuum pump or dissolved in the vacuum pump oil, causing the overall function of the vacuum pump to decline. The other part is in the vacuum pipeline. As the temperature drops, it forms colloidal particles and adsorbs on the vacuum pipeline. Over time, the vacuum pipeline will become narrower or even blocked, which is easy to cause equipment failure.

[0003] In view of the above situation, a filter device needs to be added to the laminator to filter the oil of the vacuum pump to ensure the normal use of the laminator. At present, the oil pipeline of the vacuum pump is set inside the laminator, and the filter device is also set inside the laminator and connected to the oil pipeline. However, since the filter element in the filter device needs to be replaced regularly, the laminator needs to be dismantled when replacing it, which is complicated and inconvenient to replace the filter element.

[0004] Therefore, it is an urgent problem for those skilled in the art to develop a laminated vacuum pump oil circulation filtration system for solar panel processing with easy filter element replacement. Utility Model Content

[0005] In view of this, the utility model provides a laminated vacuum pump oil circulation filtration system for solar module processing with easy filter element replacement.

[0013] Preferably, an oil inlet pipe is provided at the oil inlet, and a buffer cover is provided at the bottom of the oil outlet end of the oil inlet pipe. After the oil comes out of the oil inlet pipe, it falls along the buffer cover, which can slow down the falling speed of the oil and avoid bubbles when the oil falls.

[0014] Preferably, the buffer cover is in an inverted funnel shape, and the top of the buffer cover is closed. The buffer cover can make the oil scatter to all sides.

[0016] Preferably, a limiting ring is provided on the inner wall of the housing, and the filter element is placed on the top of the limiting ring. The limiting ring can limit the position of the filter element.

[0017] Preferably, a pressure ring is provided below the buffer cover, and the pressure ring presses the top of the filter element. The pressure ring and the limit ring can limit the position of the filter element.

[0018] Preferably, a connecting rod is provided at the bottom of the buffer cover, and the connecting rod is connected to the pressure ring.

[0019] Preferably, a liquid level sensor is provided inside the housing, and the liquid level sensor is located below the filter element. The liquid level sensor can monitor the oil in the housing, and when the filter element is clogged and the liquid level does not meet the requirement, an alarm will be issued to prompt the staff to replace the filter element.

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] The utility model embodiment discloses a laminating vacuum pump oil circulation filtration system for solar module processing, comprising:

[0039] The housing 1 is arranged outside the laminator; the top of the housing 1 is open, and an oil outlet 11 is provided at the bottom;

[0040] A top cover 2, which is buckled on the top of the housing 1 and is provided with an oil inlet, which is communicated with the interior of the housing 1;

[0041] The filter element 3 is arranged inside the housing 1 and below the oil inlet.

[0042] In order to further optimize the above technical solution, a first flange 12 is provided on the outer wall of the top of the housing 1, and a second flange 21 is provided on the outer circumferential surface of the top cover 2. The first flange 12 and the second flange 21 are buckled and connected. The first flange 21 and the second flange 21 are fixed by bolts.

[0043] In order to further optimize the above technical solution, an oil inlet pipe 4 is provided at the oil inlet, and a buffer cover 5 is provided at the bottom of the oil outlet end of the oil inlet pipe 4.

[0044] In order to further optimize the above technical solution, the buffer cover 5 is in an inverted funnel shape, and the top of the buffer cover 5 is closed. The top of the buffer cover 5 is a plane, which can first buffer the oil and reduce the flow rate of the oil.

[0045] In order to further optimize the above technical solution, a connecting frame 6 is provided on the outer tube wall of the oil outlet end of the oil inlet pipe 4, and the connecting frame 6 is connected to the buffer cover 5. A plurality of connecting frames 6 are evenly provided around the side wall of the buffer cover 5.

[0046] In order to further optimize the above technical solution, a limiting ring 13 is provided on the inner wall of the housing 1 , and the filter element 3 is placed on the top of the limiting ring 13 .

[0047] In order to further optimize the above technical solution, a pressure ring 7 is arranged below the buffer cover 5, and the pressure ring 7 presses the top of the filter element 3. When filtering the oil, a part of the oil will be stored on the top of the filter element 3. The arrangement of the pressure ring 7 and the limit ring 13 can play a role in fixing and limiting the filter element 3, preventing the oil from affecting the position of the filter element 3.

[0048] In order to further optimize the above technical solution, a connecting rod 8 is provided at the bottom of the buffer cover 5, and the connecting rod 8 is connected to the pressure ring 7. A plurality of connecting rods 8 are provided around the pressure ring 7.

[0049] In order to further optimize the above technical solution, a liquid level sensor 9 is provided inside the housing 1, and the liquid level sensor 9 is located below the filter element. When the filter element 3 can filter normally, a certain height of oil will be maintained below the filter element 3. Once the filter element 3 is clogged by impurities and the filtering is not smooth, the filtering speed of the oil will decrease, and the oil height below the filter element 3 will also decrease. When it drops below the liquid level sensor 9, the liquid level sensor 9 will sound an alarm, prompting the staff to replace the filter element.

[0050] In order to further optimize the above technical solution, the oil inlet pipe 4 is connected to the multi-pipe joint 10, and is simultaneously connected to the oil in multiple vacuum pumps through the multi-pipe joint 10. The multi-pipe joint 10 can be a two-way, three-way, four-way or other multi-way joint, and a suitable joint can be appropriately replaced as needed. The same pipe joint is set at the oil inlet pipe 4 and the oil outlet 11 to realize the use of multiple machines.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
