Description

Technical Field

[0001] The utility model relates to filtering equipment, in particular to color fixing agent pressure filtering equipment. Background Art

[0002] A color fixative is a chemical used in dyeing or coating processes that allows dyes or pigments to adhere firmly to the surface of a material, thereby maintaining the color's long-lasting brightness. Color fixatives are usually organic compounds, such as sulfates, aldehydes, phenols, zinc salts, etc. In dyeing or coating processes, these compounds can combine with dyes or pigments to form stable chemical bonds, thereby fixing the color. However, during the production of color fixatives, some impurities and particles may be generated. If these substances are not filtered out and removed, they may affect the quality and performance of the color fixative. Utility Model Content

DETAILED DESCRIPTION

[0011] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0012] Embodiment. A color fixing agent pressure filtering device, comprising: Figure 1 As shown, it includes a body 1, wherein the upper end of the body 1 is provided with a liquid inlet pipe 2, the liquid inlet pipe 2 is provided with a control valve 8 and a first one-way valve 9 that can only flow in the direction of liquid inlet to the body 1, and the lower end of the body 1 is provided with a liquid outlet pipe 3, the liquid outlet pipe 3 is provided with a control valve 8 and a second one-way valve 10 that can only flow in the direction of liquid outlet from the body 1; a sieve plate 4 is provided inside the body 1, a support tube 5 fixed to the top of the inner side of the body 1 is provided on the upper side of the sieve plate 4, an elastic air bag 6 is provided outside the support tube 5, and an air charging and discharging port 7 corresponding to the elastic air bag 6 is provided on the upper side of the body 1; a lining plate 13 is provided on the lower side of the elastic air bag 6, a fixed seat 14 is provided in the middle part of the lower side of the lining plate 13, a rotating rod 15 that can rotate relative to the fixed seat 14 and is vertically arranged is provided in the fixed seat 14, a cross bar 17 is provided at the lower end of the rotating rod 15, and the lower side of the cross bar 17 is connected to a cleaning brush 12 arranged on the upper side of the sieve plate 4 through a connecting rod 16.

[0013] Limit blocks 20 are provided at both ends of the cleaning brush 12 .

[0014] The connecting rod 16 is a telescopic rod.

[0015] The inner wall of the machine body 1 is provided with a guide groove 18 corresponding to the cross bar 17 , and the guide groove 18 is spirally arranged. The inner wall of the machine body 1 is also provided with a limit groove 19 corresponding to the upper limit block 20 of the cleaning brush 12 .

[0016] Principle of the utility model: During the use of the present application, the control valve 8 is in an open state, and liquid is introduced through the liquid inlet pipe 2. When the elastic airbag 6 is deflated, the volume of the elastic airbag 6 is reduced, thereby changing the pressure in the body 1, and the color fixing agent enters from the liquid inlet pipe 2. Then the elastic airbag 6 is inflated, thereby pressurizing the liquid in the body 1. The liquid cannot be discharged from the liquid inlet pipe 2 due to the first one-way valve 9 on the liquid inlet pipe 2. The liquid passes through the sieve plate 4 and is discharged from the liquid outlet pipe 3 to achieve pressurized filtration. In addition, during the inflation of the elastic airbag 6, the lining plate 13 will move downward, so that the rotating rod 15 and the cross bar 17 under the lining plate 13 will rotate under the action of the guide groove 18, so that the cleaning brush 12 will rotate on the sieve plate 4 to clean the sieve plate 4, and the connecting rod 16 is a telescopic rod, which can adapt to the change in the distance between the cleaning brush 12 and the lining plate 13 during the deformation of the elastic airbag 6.
