Cosmetics dust-free purification pharmaceutical cleanroom solid-liquid separation equipment
In order to ensure the stability of the product in the cosmetic dust-free workshop, solid-liquid separation equipment is often used in the industry to prevent the solid deposition phenomenon after the product is stored for a long time. Filter; the commonly used solid-liquid separation equipment in cosmetic workshops is plate and frame filter press and cartridge filter. The plate and frame filter press is composed of pressing plate, thrust plate, filter medium, filter frame, filter plate, pressing device, liquid collecting tank and other parts. The plate and frame filter press consists of a series of filter plates and The filter frame is composed of a colloid arrangement, the surface of the filter plate is provided with grooves, the filter frame is hollow, and the filter cloth is pressed between the filter plate and the filter frame to form a filter chamber; during operation, the feed liquid to be filtered is passed through the conveying pump from the feeding hole. After entering the filter chamber, the solid material is trapped in the filter chamber by the filter cloth and gradually forms a filter cake, and the filtrate is drained through the filter plate groove to the plate and frame channel and then discharged; In order to remove the excess washing liquid, after all the processes are completed, remove the filter plate in the filter press to remove the filter residue and clean the filter cloth, and then reinstall it to complete a filtration cycle.
Cylinder filter is composed of connecting pipe, cylinder, filter element, flange, flange cover and fasteners, etc. It can be installed in the pipeline. The material generates a certain pressure under the operation of the pump, and is transported to the equipment equipped with After the cylinder of the filter element, the solid material is blocked by the filter element, and the filtrate passes through the filter element and flows out from the lower part of the cylinder body; as the operation time prolongs, the filter cake layer becomes thicker and thicker, resulting in a gradual increase in the filtration resistance and pressure difference. Then the filtration process is terminated after the permeability is reduced to a certain extent; when using a cartridge filter, it is necessary to pay attention to the fatigue damage of the filter, because the material fluid flows through a series of cylindrical filter elements during filtration, and the downstream of the arrayed cylindrical filter elements Vortex will be formed alternately at the filter, and the continuous shedding of these vortices will cause the filter element to resonate, thereby destroying the normal operation of the filter and damaging the machine; in addition, when the fluid flows through the filter element, most of the fluid is in a turbulent flow state, and the pulsating speed in the turbulent flow will induce the filter element. vibration, which can damage the machine. Different from the plate-and-frame filter, it is difficult to disassemble and install the cylinder, and it is not feasible to clean the filter by disassembly. After the filtration operation is stopped, the cleaning solution in the opposite direction of the flow direction of the filter is introduced to the filter to remove the deposits on the surface of the filter element. filter cake. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for cosmetic dust-free workshops and purification workshops.
Bacteria in cosmetic products or raw materials will seriously affect the appearance and stability of the products, because the raw materials or semi-finished products must be sterilized before or after production. The commonly used sterilization methods in production include chemical treatment. bacteria, heat treatment sterilization and ultraviolet sterilization, no matter which method is used, it must have the characteristics of efficient sterilization ability, safety and reliability, and convenient operation process.
