Description

Technical Field

[0001] The present invention belongs to the technical field of pharmaceutical equipment, and particularly relates to a spherical-cone-shaped special multi-functional machine, which is mainly applied to the production in the pharmaceutical, chemical and flammable and explosive industries. Background Art

[0002] At present, existing multi-functional integrated machines at home and abroad, such as spherical multi-functional machines, vertical "three-in-one" machines, barrel-cone "three-in-one" machines, etc., all have insurmountable functional drawbacks due to the mutual restriction between the filtration area and the heating area. The advantages of the vertical multi-functional machine are good filtration and washing effects, but the effective heating area is too small, the drying function is poor, the filter plates are caked, and there are many fatal defects such as a lot of residue during discharging. It is more suitable for filtration and washing in one. The spherical multi-functional machine has a good drying effect and a crystallization function. However, there are problems such as too small a charging coefficient, easy damage to the shaft seal during feeding, very difficult maintenance, too small a filtration area, easy blockage and airtightness of the filter plates during stirring, and a lot of residue during discharging. Especially during spraying or layer washing, there are fatal defects in the short-circuit dead corners formed on the lower arc surface. The barrel-cone three-in-one has a large filtration area and a large charging volume. Since the cone is a filtration structure, it cannot effectively exchange heat. It mainly relies on the spiral belt on the main shaft for heating, and the drying function is very poor. At the same time, the conical filter plates are involved in the whole process of drying and rolling, and the conical filter plates are seriously caked, making cleaning and washing difficult. The "spherical-cone-shaped special multi-functional machine" of the present invention highlights the advantages of the above-mentioned equipment and overcomes the fatal defects. The cone is used for filtration and washing, and the sphere is used for rapid drying, integrating the advantages of the large filtration area of the barrel-cone three-in-one and having the advantages of fast multi-functional drying of the sphere. At the same time, problems such as a lot of residue during discharging are solved.

[0003] In industries such as pharmaceuticals, fine chemicals and chemicals, the requirement for green and intelligent production is imperative. In the production process of most products, most are completed by five independent technological processes: reaction crystallization of materials, solid-liquid separation, washing, drying, crushing, and automatic discharging. And most raw materials are flammable, explosive, toxic, harmful and expensive solvents. Usually, five different devices, namely reaction kettles, centrifuges, washing tanks, dryers, and crushers, are used independently to complete them. Therefore, during the production process or material transfer, it is inevitable that toxic, harmful, odorous, flammable and explosive gases or liquids leak into the production environment, causing serious pollution and safety hazards. Accidents occur from time to time, posing a great threat to life and property safety. This is a long-standing and difficult problem that enterprises urgently need to solve. There is an urgent need to develop a multi-functional machine that can integrate the above five technological processes in one machine and can solve the fatal problems existing in the original multi-functional machine, so as to achieve automated, enclosed and intelligent production.

[0029] 6. The scraping end of the scraping blade of the scraping device of the present invention is an arc-shaped structure, and the running tracks of multiple scraping blades cover the entire inner wall of the hemispherical body. One side of the scraping blade in the middle part of the main shaft is provided with an inclined plate, which forms an angle less than 90 degrees with the tangent of the rotation track, so as to compact the cracks on the upper surface of the filter cake of the filtered material.
