Tsukishima Kikai Co., Ltd. Product Lineup

The "TSK Tray Filter" is a batch-type filter capable of functional filtration processing. It has numerous usage records in the production processes of products for small quantities and a wide variety of filtration, washing, and dewatering. Since it allows for the arbitrary selection of necessary and sufficient time for each single operation process of filtration, washing, dewatering, discharge, and cloth washing, it enables suitable processing tailored to the material being treated. Additionally, because the filtration surface is oriented upwards, it can efficiently handle everything from slurries of coarse particles with a fast settling velocity to slurries of fine particles that are difficult to filter. 【Features】 ■ Wide range of applications ■ Compatible with coarse to fine particles ■ Suitable for multi-variety processing ■ Simple structure allows for fully automatic operation ■ High yield ■ Heavy-duty specifications are also available ■ Easy operation *For more details, please refer to the PDF document or feel free to contact us.

The "Tsukishima Precoat Filter" is a revolutionary continuous filtration device that performs clear filtration. It is a drum-type filter developed for clear filtration of slurries with a very low solid concentration (0.03%) that cannot be filtered by ordinary vacuum filters. By attaching various options, it can also support fully automated operation controlled by a computer. Additionally, the filter cloth is stretched over the drum surface, and filtration begins after pre-coating with filtration aids around 120 m/m, allowing for the acquisition of sufficiently satisfactory clear filtrate. 【Features】 ■ High clarity ■ Highly accurate scraper feeding mechanism ■ Capable of automatic operation ■ Adopts a one-port valve-less structure for filtrate extraction ■ High filtration speed *For more details, please refer to the PDF materials or feel free to contact us.

**[Principle]** The slurry is supplied onto a continuously moving filter cloth, and continuous vacuum filtration is performed by suction from a vacuum tray that reciprocates along the direction of the filter cloth. A cake washing liquid is supplied onto the uniformly formed cake layer on the filter cloth, uniformly replacing the mother liquor within the cake with the cake washing liquid. The solid product after filtration, washing, and dewatering is continuously discharged outside the device by a cake peeling mechanism. The filter cloth is constantly cleaned by a filter cloth cleaning device to prevent clogging. **[Features]** Excellent cake washing capability Since a uniform cake layer is formed, there are no washing inconsistencies. The washing time and length can be optimally set, allowing for thorough cake washing operations. Significant reduction in wastewater treatment costs Efficient replacement washing allows for a reduction in the amount of washing water used. Additionally, further reduction in cake washing water volume is possible through counterflow multi-stage washing operations. Complete recovery of products The cake peeling mechanism ensures a high product recovery rate. By recycling the filter cloth cleaning liquid as the cake washing liquid, complete recovery of solid products is achievable. Possibility of a fully sealed design A fully sealed design is also applicable for processing solvent-based slurries and similar materials.

**Features** 1. The filter cloth is always clean The filter cloth is continuously cleaned from both sides by a spray nozzle after cake removal, ensuring that filtration continues without clogging. By installing an acid trough, it can also accommodate chemical cleaning without removing the filter cloth. 2. Cake removal is reliable The cake formed on the filter cloth is detached by rapid inversion using a small-diameter discharge roll. The roll is wrapped with stainless steel wire in a spiral, which forces the cake to be scraped off from the back of the filter cloth. This method allows for complete removal even at a thickness of 2mm, which is impossible with other types of filtration machines. 3. Easy filter cloth replacement The endless connection of the filter cloth uses zippers, racing, high-frequency welding, etc., allowing one person to complete the replacement in about 30 minutes. 4. Revolutionary filter cloth deviation correction device The filter cloth deviation correction device has three methods: twin roll, guide roller, and split roll, adopting the method suitable for the processed material. All methods automatically correct deviations reliably, enabling unmanned operation. 5. No grease gun required An automatic centralized lubrication system provides forced lubrication to all rotating and sliding parts. Therefore, manual lubrication is unnecessary, significantly reducing maintenance efforts.

This is a long-selling filter that features continuous filtration, washing, and dewatering of difficult-to-process materials with clogging, and is more cost-effective than belt filters, easier to maintain, and requires less installation space, making it widely used in various fields. 【Features】 1. Scraper Discharge Type This method uses backflow to lift the cake off the filter medium, which is then scraped off with a scraper. It is the most common method and is suitable for cakes made of non-sticky substances. 2. Roller Discharge Type This method presses a roller against the cake and scrapes off the wrapped cake with a scraper. It is suitable for sticky cakes that are difficult to detach with backflow. 3. Precoat Cut Type This method scrapes the cake off with a scraper under vacuum without backflow. Each time, the cake formed on top of the remaining cake (precoat layer) is scraped off. The precoat layer clogs over time, so it is intermittently peeled off and renewed. Since it is scraped under vacuum, there is no backflow of filtrate due to backflow, and the moisture content of the cake is reduced by 2-4%. It is applicable to materials with a relatively good filtration property and uniform particle size.
