Description

Technical Field

[0001] The utility model relates to the technical field of paint production equipment, in particular to a filtering device. Background Art

[0002] During the paint production process, it is necessary to filter impurities in the paint, which requires the use of a filtering device. Currently, the filtering device for filtering paint generally includes an outer barrel body, a barrel cover installed at the upper end of the outer barrel body, and a filtering cylinder installed inside the outer barrel body. However, at present, there is a gap between the upper end of the filtering cylinder installed in the outer barrel body and the barrel cover. In this way, once the flow rate of the paint entering the filtering cylinder is greater than the flow rate of the paint flowing out of the filtering cylinder, the paint in the filtering cylinder will overflow from the opening at the upper end of the filtering cylinder, thus failing to filter the paint effectively.

[0003] To solve the above problems, the prior art patent (CN211635458U) discloses a paint production filtering device, which includes an outer barrel body and a barrel cover sealedly installed on the outer barrel body. The barrel cover is detachably connected to the outer barrel body. The bottom of the outer barrel body is communicated with a paint outlet pipe, and the middle of the barrel cover is communicated with a paint inlet pipe. A filtering cylinder is installed inside the outer barrel body. There is a gap between the lower end of the filtering cylinder and the inner bottom of the outer barrel body. The upper end of the filtering cylinder abuts against the lower surface of the barrel cover outside the paint inlet pipe. A sealing structure is arranged between the upper end of the filtering cylinder and the barrel cover. After the sealing structure is arranged between the upper end of the filtering cylinder and the barrel cover in the utility model, when the flow rate of the paint entering the filtering cylinder is greater than the flow rate of the paint flowing out of the filtering cylinder, it can prevent the paint in the filtering cylinder from overflowing from the opening at the upper end of the filtering cylinder, thus ensuring reliable filtering of the paint.

[0004] However, in the above prior art, due to the high viscosity and poor fluidity of the paint, directly filtering the paint will result in low efficiency. Summary of the Utility Model

The heat exchanger is fixedly connected to the circulation tank and is located above the circulation tank. The heating tank is fixedly connected to the heat exchanger and is located outside the circulation tank. The inner tank is fixedly connected to the heating tank and is located inside the heating tank. The sealing sleeve is fixedly connected to the heating tank and is located outside the inner tank. The water inlet valve is fixedly connected to the inner tank and is located above the inner tank. The drain valve is fixedly connected to the inner tank and is located below the inner tank. The extension plate is fixedly connected to the heating tank and is located outside the heating tank. The temperature control component is fixedly connected to the extension plate and is located below the sealing sleeve.

The foregoing solution solves the problem that directly filtering the paint will result in low efficiency due to the high viscosity and poor fluidity of the paint.

[0023] For this specific embodiment, the flow-through pipe 102 is fixedly connected to the circulation tank 101 and penetrates through the circulation tank 101. The heating assembly includes a heat exchanger, a heating tank 103, an inner tank 104, a sealing sleeve 105, a water inlet valve 106, a drain valve 107, an extension plate 108, and a temperature control device. The heat exchanger is fixedly connected to the circulation tank 101 and is located above the circulation tank 101. The heating tank 103 is fixedly connected to the heat exchanger and is located outside the circulation tank 101. The inner tank 104 is fixedly connected to the heating tank 103 and is located inside the heating tank 103.

The drain valve 107 is fixedly connected to the inner tank 104 and is located below the inner tank 104. The extension plate 108 is fixedly connected to the heating tank 103 and is located outside the heating tank 103. The temperature control device is fixedly connected to the extension plate 108 and is located below the sealing sleeve 105. Open the water inlet valve 106 to fill the inner tank 104 with water. The extension plate 108 bears the temperature control device, and the temperature control device heats the inner tank 104. The heating tank 103 prevents heat loss. The sealing sleeve 105 improves the sealing performance between the inner tank 104 and the heating tank 103, thereby heating the water in the inner tank 104. After heating is completed, the heat exchanger operates to output the hot water in the inner tank 104 into the circulation tank 101. After the transportation is completed, the water inlet valve 106 continues to input clean water. After heating the clean water is completed, the heat exchanger circulates the water in the inner tank 104 and the water in the circulation tank 101. The paint flows from the flow-through pipe 102 to the filtering mechanism, and the hot water in the circulation tank 101 heats the flow-through pipe 102, thereby realizing the heating of the paint flowing in the pipe.

[0025] Secondly, the second booster pump 111 is fixedly connected to the heating tank 103 and is located above the heating tank 103. The water outlet pipe 112 is fixedly connected to the input end of the second booster pump 111 and is located within the circulation tank 101. When the second booster pump 111 operates, the water outlet pipe 112 pumps the water within the circulation tank 101 into the inner tank 104.

[0026] Meanwhile, the heater 113 is electrically connected to the connection plate 114 and is located above the extension plate 108. The connection plate 114 is fixedly connected to the inner tank 104 and is located within the heating tank 103. A plurality of heating bars 115 are fixedly connected to the connection plate 114 and are located outside the inner tank 104. When the heater 113 operates, it drives the plurality of heating bars 115 to operate through the connection plate 114, and the heating bars 115 heat the inner tank 104.

[0027] In addition, the heating tank 103 has a cavity 116, and the temperature control device performs a heating operation on the inner tank 104 within the cavity 116.

[0028] When using a filtering device according to this embodiment, by providing the flow-through pipe 102 and the heating assembly, during actual use, the water inlet valve 106 is opened to fill the inner tank 104 with water. The heater 113 operates to drive the plurality of heating bars 115 to operate through the connection plate 114, and the heating bars 115 heat the inner tank 104.

After the water in the inner tank 104 is heated, the first booster pump 109 operates, and the water inlet pipe 110 pumps the hot water in the inner tank 104 into the circulation tank 101. After the transportation is completed, the water inlet valve 106 continues to input clean water, and the paint flows from the flow-through pipe 102 to the filtering mechanism. The hot water in the circulation tank 101 heats the flow-through pipe 102, thereby realizing the heating of the paint flowing in the pipe. After the water in the inner tank 104 is heated for the second time, the first booster pump 109 operates, and the water inlet pipe 110 pumps the hot water in the inner tank 104 into the circulation tank 101. The second booster pump 111 operates, and the water outlet pipe 112 pumps the water in the circulation tank 101 into the inner tank 104, thereby realizing the hot water circulation between the inner tank 104 and the circulation tank 101, improving the heating effect on the paint. After the operation is completed, opening the drain valve 107 can drain the water in the device, which can effectively heat the paint before filtering, improve the viscosity and fluidity of the paint, and thus improve the efficiency of the paint filtering operation.
