Abstract: A spray gun (1) forms a desired spray pattern by atomizing by means of atomizing air (A) a spray liquid which is sprayed from a liquid ejection port (44) opened/closed by a needle valve (4), and jetting pattern air (P) to the flow of spray mist of the atomized spray liquid. A nozzle taper angle (?1) is set in a range of 5° to 15°, and a cap taper angle (?2) is set in a range of 20° to 40°. Atomizing air (A) is jetted from a nozzle insertion hole (58) toward the center of a nozzle (3). Pattern air (P) is jetted in a spreading suppressed region (R) wherein the flow of the spray mist does not spread over an area greater than or equal to a predetermined cross-sectional area, to the flow of spray mist, and as a result, the spray mist is more uniformly sprayed over a wide range.

Abstract: A filter cleaning apparatus 1 is a device designed exclusively for cleaning a cartridge filter used in a fluidized bed granulator. A cleaning liquid 10 is reserved in a processing container 2. In the processing container 2, a cartridge filter 3 is placed in the state of being immersed in the cleaning liquid 10. The filter 3 is so disposed as to be capable of rotating around a rotational axis line O that is substantially horizontal in the processing container 2. Air nozzles 8 are disposed below the cartridge filter 3. An uplift pressure of bubbles rising out of the liquid into the atmosphere is added to a bubble flow BF jetted from the air nozzles 8. As a result of the synergic effect of the jet pressure of the bubble flow BF and the uplift pressure, the filter 3 rotates in an efficient way, leading to an improvement in cleaning efficiency.

Abstract: Processing vessel (1) is formed by overlaying a filter casing (2), a spray casing (3), a material container (4) and an air supply unit (5). Airtightnesses between respective units are maintained by airtight junctions (61 to 63). In the airtight junction (61), two seal portions (91 and 92) are radially provided, and U-seals (64 and 65) are contained. The U-seals (64 and 65) vertically move within seal grooves (67 and 68) through supply and exhaust of air to/from cylinder chambers (69 and 71), to thereby attain close contact with or detachment from flange (74). During particulate material processing, the airtightness of the seal portion (91) is maintained by the U-seal (64). During processing vessel washing, the airtightness of the seal portion (92) is maintained by the U-seal (65), to thereby prevent exposure thereof. Simultaneously, the U-seal (64) is raised, to thereby attain washing of the seal portion (S1) during the particulate processing.

Abstract: A hollow rotating drum 3 is rotatably arranged in an outside casing 7. On the outer circumference surface of the drum 3, along the circumferential direction thereof, there are formed ventilation sections 6 that can ventilate the inside and outside of the drum 3 in the coating processing. The ventilation sections 6 are arranged over the entire circumference of the outer circumference surface of the drum 3. In the ventilation sections 6, hollow pipes 16 through which cold air circulate are arranged with a predetermined clearance provided therebetween. Communication regions that make the inside of the drum 3 communicate with the outside thereof are formed by the clearance provided between the pipes 16. During the coating processing, arbitrarily, cold air is supplied to the pipes 16 to cool the drum 3, and the temperature difference is brought about between the inner surface of the drum 3 and products to be processed, which can prevent the coating base material from adhering to the inner surface of the drum 3.

Abstract: A cartridge filter 7 is vertically movably placed in a processing vessel 1 having a cylindrical profile. An ultrasonic washer 55 is fitted to the lateral wall 3a of the spray casing of the processing vessel 1. Washing liquid 56 is injected into the processing vessel 1 and the filter 7 is moved downward and immersed in the washing liquid 56. The washer 55 is activated under this condition to wash the filter 7. Since the washer 55 is arranged near the filter 7, the ultrasonic oscillation is easily transmitted to the filter 7 to efficiently remove the foreign objects adhering to the filter 7. Thus, with this arrangement, it is possible to wash the filter 7 in the processing vessel 1 without removing the filter 7 from a fluidized bed apparatus. In a filter washing apparatus 101, a cartridge filter 103 is contained in a processing vessel 102 and immersed in washing liquid 110.

Abstract: A rotating drum 3 has ventilation sections 6 that can ventilate the inside of the drum and the outside of the drum in the coating processing. To the ventilation sections 6, a panel unit 41 having arranged therein plural hollow pipes 42 through which cold water passes is attached. The hollow pipes 42 are fixed to a base plate 44 in parallel with each other, and a gap “G” is provided between the adjacent pipes. The base plate 44 is provided with a communication hole 45, and the hollow pipes 42 are so arranged as to face the communication hole 45. To both ends of the hollow pipes 42, charge/discharge collecting pipes 46a and 46b are fixed. In the coating processing, cold water is arbitrarily supplied to the hollow pipes 42 through the charge/discharge collecting pipe 46a to cool the drum 3 so as to bring about the temperature difference between the inside of the drum and processing objects, which can prevent coating base materials from adhering to the inside of the drum.
