Drug residue solid-liquid separator

The drug residue solid-liquid separator is a mechanical device specially used to process the drug residue produced in the pharmaceutical process and effectively separate the solid and liquid in it. This type of equipment usually uses physical or chemical methods, combined with advanced mechanical design, to achieve efficient dehydration, reduction and resource utilization of drug residues. The following are the main working principles, characteristics and applications of drug residue solid-liquid separators: Working principle of drug residue solid-liquid separators: 1. Physical separation: Drug residue solid-liquid separators usually use physical methods for solid-liquid separation, such as centrifugal separation, filter press separation, screw extrusion separation, etc. Centrifugal separation uses the centrifugal force generated by high-speed rotation to separate the solid and liquid phases in the drug residue due to density differences; filter press separation applies pressure to the drug residue through filter cloth or filter plate, so that the liquid flows out through the filter hole, and the solid is retained to form a filter cake; spiral extrusion separation uses the spiral shaft to strongly squeeze the drug residue, forcing the liquid to be discharged, and the solid is spirally transported to the discharge port. 2. Chemical pretreatment: In some cases, it may be necessary to chemically pretreat the drug residue, such as adding flocculants to aggregate fine solid particles into large flocs that are easy to separate, thereby improving the subsequent separation efficiency. 3. Dehydration and compression: The slag solid-liquid separator will deeply dehydrate the slag during the separation process, and squeeze out as much water as possible from the slag through mechanical force to form a solid residue with a low moisture content. This process helps to significantly reduce the volume of the slag, reduce the burden of subsequent disposal, and may help to increase the value of the resource utilization of the slag. Features of the slag solid-liquid separator: - Efficient separation: The slag solid-liquid separator is precisely designed and can quickly and accurately separate the solid and liquid phases in the slag, with good separation effect. The separated liquid is clear and the solid is dry. - Strong adaptability: For slags of different properties (such as Chinese medicine slag and Western medicine slag), the corresponding separation parameters and processes can be selected or adjusted to adapt to different material characteristics and processing requirements. - High degree of automation: Modern slag solid-liquid separators are usually equipped with an automated control system, which can realize functions such as continuous feeding, continuous separation, and automatic slag discharge, reduce manual intervention, and improve operating efficiency. - Energy saving and environmental protection: The equipment has low energy consumption, and the separation process usually does not require the addition of a large amount of chemical agents, reducing the impact on the environment. The volume of the solid drug residue after separation is greatly reduced, which is convenient for transportation and disposal, and helps to reduce the overall processing cost. Application of drug residue solid-liquid separator: - Pharmaceutical industry: Mainly used in pharmaceutical companies to treat various drug residues generated in the production process, such as Chinese medicine decoction residues, Western medicine preparation residues, waste activated carbon, etc., to achieve waste reduction and resource utilization. - Pharmaceutical waste treatment center: Centrally treat drug residues from multiple pharmaceutical companies, and use solid-liquid separation as a pretreatment step for subsequent harmless and resource-based treatment (such as incineration, composting, biodegradation, etc.). - Scientific research institutions: In the process of drug research and development, it is used to treat drug residues generated by experiments to ensure the safe and compliant disposal of laboratory waste. - Environmental protection company: When environmental protection service companies provide drug residue treatment services, they may use drug residue solid-liquid separators as core equipment to provide drug residue treatment solutions for pharmaceutical companies. In short, drug residue solid-liquid separators are important equipment for waste treatment in the pharmaceutical industry. By efficiently separating the solid and liquid phases in drug residues, it not only helps to reduce the volume of waste and reduce treatment costs, but also helps to realize the resource utilization of drug residues, which is in line with the development trend of green pharmaceuticals and circular economy.
