Abstract
Description
Technical Field
[0001] The present application relates to the field of pigment slurry desalination and separation, and in particular to a device for pigment desalination and filtration. Background Art
[0002] After pretreatment, the pigment needs to be desalted and decontaminated. Currently, the desalination of pigment slurry is almost always done by using a filter press washing process, which causes a large waste of energy. Later improvements are only to recycle water to save water, which also increases water consumption. In addition, the desalination and separation conditions of the pigment slurry are complicated, which affects work efficiency. Summary of the invention
[0003] To solve the above problems, the present invention discloses a device for pigment desalination and filtration. The utility model relates to the field of pigment slurry desalination and separation. The device itself has low cost and is easy to maintain. It utilizes the piston principle to circulate multiple times and finally remove the salt in the pigment.
[0004] A device for pigment desalination and filtration comprises a cylinder body, wherein a movable stabilizing seat is provided on the top of the cylinder body; a piston rod passes through the movable stabilizing seat and is connected with a piston in the cylinder body; wherein the piston is provided with a filter hole; a filter cloth is provided on the surface of the filter hole; a liquid outlet is provided on one side of the cylinder body and a liquid inlet is provided on the other end; and a slurry inlet is provided at the lower end of the cylinder body.
[0005] Furthermore, the outer surface of the piston should have an O-ring to ensure sealing.
[0006] Furthermore, the filter cloth is connected to the piston via a filter cloth flange.
[0007] Furthermore, the liquid outlet is connected to a negative pressure tube.
[0008] Furthermore, a switch valve is provided at the slurry inlet.
[0009] The utility model utilizes the working principle of the piston and can filter out the moisture in the slurry at a relatively fast rate. When the switch valve at the slurry inlet is opened and the slurry is added into the cylinder body, the slurry will be separated, with the upper layer being clear liquid and the lower layer being pigment. At this time, the piston is pressed down again, and the upper clear liquid passes through the filter cloth and is separated from the pigment smoothly. Subsequently, the filtrate is sucked out by the negative pressure pipe, and then the slurry is beaten for the second time and water is added. After the clear water passes through the filter cloth and is mixed with the pigment and allowed to stand, the piston is pressed down again. After multiple cycles, the salt in the pigment can be completely removed.
[0010] Beneficial effects of the utility model:
[0011] 1. The equipment itself is low in cost and easy to maintain. Subsequent maintenance only requires replacement of sealing parts such as O-rings;
[0012] 2. High desalination efficiency, saving time, one stroke of the piston can filter out the liquid;
[0013] 3. Water saving: compared with the traditional filter press washing water consumption of as little as 50 to 60 tons, this filtration device only requires 1 / 3 of the amount. BRIEF DESCRIPTION OF THE DRAWINGS
