Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a filter screen cleaning equipment. Background Art

[0002] At present, the filter screen inside the silicon wafer slicer filter in the photovoltaic industry needs to be cleaned regularly. Since the cleaning process is relatively complicated and takes a long time, ultrasonic cleaning equipment can be used in the existing technology to achieve automatic cleaning of the filter screen to improve the cleaning effect and efficiency. However, the related cleaning equipment in the existing technology can either only place one cylindrical filter screen in a device for cleaning at a time, resulting in low cleaning efficiency, or increase the volume of the cleaning tank in the cleaning equipment to place multiple cylindrical filter screens for cleaning at a time. However, the multiple cylindrical filter screens cannot be well positioned during the cleaning process and are prone to collision with each other. In addition, the increase in the volume of the cleaning tank will lead to a decrease in the cavitation effect of ultrasonic waves in the cleaning liquid, which reduces the cleaning effect and requires the consumption of more cleaning agents, increasing the cleaning cost and being detrimental to environmental protection.

Specific Embodiments

[0020] The following details the embodiments of the present utility model, referring to Figures 1 to 3, an embodiment of the present utility model provides a filter screen cleaning device, including a device main body 100. The device main body 100 is provided with a cleaning tank 110. A plurality of positioning bumps 200 are protrudingly provided on the side wall of the cleaning tank 110 towards the inside of the cleaning tank 110. The plurality of positioning bumps 200 divide the cleaning tank 110 into a plurality of interconnected positioning cavities 111. This filter screen cleaning device has a plurality of positioning cavities 111 provided in the cleaning tank 110, which can be used for positioning and placing a plurality of filter screens 900. An ultrasonic vibration plate 800 can be installed in each positioning cavity 111. During cleaning, cleaning liquid or pure water can be introduced into the cleaning tank 110. Through the cavitation cleaning effect of the ultrasonic vibration plate 800 in each positioning cavity 111, a plurality of filter screens 900 can be effectively cleaned at one time, ensuring the cleaning effect and improving the cleaning efficiency. The positioning bumps 200 can not only divide the positioning cavities 111 and position the filter screens 900 to provide respective cleaning spaces for each filter screen 900, avoiding collisions between the filter screens 900 and improving the cleaning effect, but also form a placeholder in the cleaning tank 110, thereby reducing the liquid storage volume of the cleaning tank 110, reducing the amount of cleaning agent used, saving costs, and being environmentally friendly. Of course, it should be noted that the driving and working principle of the ultrasonic vibration plate 800 can refer to existing filter screen ultrasonic cleaning devices and will not be elaborated here. In addition, a bubble generator can also be installed in the positioning cavity 111. By bubble cleaning in each positioning cavity 111, a plurality of filter screens 900 can also be effectively cleaned at one time, ensuring the cleaning effect and improving the cleaning efficiency.

[0021] Furthermore, a plurality of positioning bumps 200 are circumferentially arranged around each positioning cavity 111. The positioning bumps 200 have a limiting surface 210 facing the positioning cavity 111. The plurality of positioning bumps 200 and the side walls of the cleaning tank 110 cooperate to enclose the positioning cavity 111. The ultrasonic vibration plate 800 in the positioning cavity 111 vibrates in the cleaning liquid, and the filter screen 900 is cleaned through the cavitation effect to remove impurities adhered to the surface of the filter screen 900. The limiting surface 210 on the positioning bump 200 can limit the fluctuation range of the filter screen 900 and the cleaning liquid in the positioning cavity 111, so that ultrasonic cleaning is realized in each positioning cavity 111 respectively, and the filter screens 900 do not collide and interfere with each other. Further, the positioning bump 200 is in the shape of a triangular prism. While achieving positioning and limiting, it can also form a relatively large occupation area, which can reduce the amount of cleaning agent used while ensuring the cleaning effect. Further, there are two groups of positioning bumps 200. The two groups of positioning bumps 200 are oppositely arranged on the two side walls of the cleaning tank 110, and there is a communication channel 112 between the two groups of positioning bumps 200. The communication channel 112 is used for liquid connection to facilitate the introduction of cleaning liquid or pure water for cleaning. For the positioning bumps 200 at the two ends, it has one limiting surface 210. For the positioning bumps 200 in the middle, it has two limiting surfaces 210, and the two limiting surfaces 210 face the two positioning cavities 111 respectively. Of course, it can be understood that the inner diameter of the positioning cavity 111 is larger than the outer diameter of the filter screen 900. That is, normally, there is a gap between the limiting surface 210 and the filter screen 900, so that the cleaning liquid can clean the inner and outer walls of the filter screen 900. The limiting surface 210 only plays a limiting role on the filter screen 900 when the filter screen 900 shakes with the ultrasonic vibration of the cleaning liquid, avoiding collision between the filter screens 900 and also avoiding contact between the filter screen 900 and the ultrasonic vibration plate 800.

[0022] Furthermore, an instrument keypad 140 is provided on the equipment main body 100 for the staff to operate. Further, referring to Figure 2 , Figure 2The figure shows the structural schematic diagram of the cleaning device with the back panel and part of the side panels of the device hidden. The device main body 100 also has a liquid storage tank 120 for storing cleaning liquid. The liquid storage tank 120 is connected to the cleaning tank 110 through a centrifugal pump 300 and a liquid inlet pipe 400. A liquid level sensor 121 is installed in the liquid storage tank 120, and the cleaning liquid can be alkaline water. When cleaning is required, the centrifugal pump 300 and the liquid inlet pipe 400 are used to introduce the cleaning liquid in the liquid storage tank 120 into the cleaning tank 110. After the liquid level sensor 121 senses the liquid level, the ultrasonic wave is automatically turned on for cleaning. Of course, the liquid level sensor 121 can also be installed in the cleaning tank 110. Further, a bracket mesh plate 130 is provided at the bottom of the cleaning tank 110, and there is a gap between the bracket mesh plate 130 and the bottom wall of the cleaning tank 110 to facilitate the sedimentation of impurities and sewage discharge. A cleaning liquid return valve 500 is provided between the cleaning tank 110 and the liquid storage tank 120. After the cleaning liquid enters the cleaning tank 110 from the liquid storage tank 120 and realizes the cleaning of the filter screen 900, the impurities will sink to the bottom of the cleaning tank 110 through the bracket mesh plate 130, and the cleaning liquid can flow back to the liquid storage tank 120 through the cleaning liquid return valve 500 to realize the multiple utilization of the cleaning liquid, further saving costs and reducing environmental pollution. A drain valve 600 is connected to the bottom of the cleaning tank 110. After the cleaning liquid is used multiple times, it can be discharged to a designated place for storage through the drain valve 600. By classifying the discharge, environmental pollution is avoided, and at the same time, it is convenient to replace the new cleaning liquid in the liquid storage tank 120. Further, the volume of the liquid storage tank 120 is larger than the volume of the cleaning tank 110 to facilitate introducing enough cleaning liquid into the cleaning tank 110 for cleaning. Further, a pure water inlet valve 700 is connected to the side of the cleaning tank 110. After cleaning with the cleaning liquid, pure water can be introduced into the cleaning tank 110 through the pure water inlet valve 700 to wash off the alkaline liquid on the filter screen 900, and then the pure water is discharged, and the filter screen 900 can be taken out.
