Problems solved by technology

[0011] In order to overcome the above-mentioned problems existing in the prior art, the present invention provides a novel filter separator, which can avoid the problems of filtrate contamination, stagnation and loss in the pipeline, and also meets the requirement of separating a small amount of solid-liquid mixture, and It can effectively use the waste heat to keep the filtrate warm, so as to avoid problems such as solute precipitation caused by temperature drop; in addition, during the suction filtration process, the solid and liquid move in reverse, so as to achieve the purpose of separating the solid sediment below from the liquid above

Embodiment 1

[0054] Embodiment 1: filter the method for calcium carbonate and copper sulfate mixture with filter separator of the present invention.

[0055] Calcium Carbonate 40g

[0056] Copper Sulfate 10g

[0057] 100g deionized water

[0058] The solid-liquid mixture formed above, because the upper layer contains a small amount of solid particles, the liquid presents an opalescent phenomenon. Put the novel filter of the present invention into it, connect the upper end to the vacuum pump, and turn on the vacuum pump, and the blue filtrate flows out smoothly from the elbow. When finished, unplug the hose from the vacuum pump, turn off the vacuum pump, and take out the filter. The filtrate can be easily poured out of the filter to achieve solid-liquid separation.

[0059] The above-mentioned experimental results show that the novel filter of this invention has inherited the advantages of the inverted siphon filter invented in our previous work. During most of the filtration process, t...

Embodiment 2

[0060] Embodiment 2: the method for suction filtering 80% polyethylene glycol aqueous solution with filter separator of the present invention.

[0061] Polyethylene Glycol 80%

[0062] Deionized water 20%

[0063] After polyethylene glycol is melted into a solution, water is added to make an 80% aqueous solution of polyethylene glycol. It is solid at room temperature and cannot be filtered. When the solution is placed in a constant temperature water bath at about 45 degrees, the crystallization situation is most suitable for suction filtration. The novel filter of the present invention is put into it, and the upper end is connected to a vacuum pump, and the liquid to be filtered is kept at a constant temperature in a water bath to avoid solidification during the suction filtration process. Submerge the liquid through the bottom of the filter and turn on the vacuum pump. Viscous liquid flows out of the nozzle. When the filtrate is close to the lower end of the nozzle, stop...

Embodiment 3

[0064] Embodiment 3: filter the method for potassium nitrate with filter separator of the present invention

[0065] Use 300 grams of deionized water at about 65 degrees, add about 200 grams of potassium nitrate, stir until it is basically dissolved, then add about 100 grams of calcium carbonate to form a mixed solution of calcium carbonate and potassium nitrate, and use the filter of the present invention to filter Out of potassium nitrate solution:

[0066] Put the prepared liquid to be filtered into a constant temperature water tank with a constant temperature of 65 degrees, put a new filter into it, and connect the upper end to a vacuum pump. After turning on the vacuum pump, the filtrate flows out from the nozzle smoothly, and the suction filtration process is about 10 seconds. After the suction filtration is finished, turn off the vacuum pump and take out the new filter. At this point no crystals had formed in the filter, and the liquid was poured into a beaker and all...

Abstract

The invention relates to a novel filtering separator which is characterized in that the separator is a cylinder provided with a sealing plug and comprises a suction filter located at the bottom of the cylinder and a pipe penetrating through the sealing plug, and the suction filter comprises a funnel and a filtering medium.By means of the novel filtering separator, the problem that filtrate is contaminated, or retained in the pipe or is lost is avoided, the requirement for separating trace of a solid liquid mixture is also met, waste heat can be effectively utilized to conduct heat preservation on filtrate, and thus the problem that solute is precipitated due to drop of temperature is avoided.

Description

technical field [0001] The invention relates to a novel filter separator, in particular to a filter separation device for solids. Background technique [0002] Filtering is a general term for a large class of unit operations. In the process of purifying fluids through special devices, there are many ways to filter, and a wide range of material systems are used. Solid-liquid, solid-gas, large particles, and small particles are all common. [0003] Filtration is when the liquid (or gas) in the suspension (or the heating gas containing solid particles) penetrates the medium under the action of driving force or other external force, and the solid particles and other substances are trapped by the filter medium, so that the solid and other substances and the liquid ( or gas) separation operation. [0004] Suction filtration is vacuum filtration. The air pump is used to reduce the pressure in the filter bottle to achieve the purpose of solid-liquid separation. Common devices in...
