Description

Anti-stacking spray dryer Technical Field The utility model relates to the technical field of spray drying equipment, in particular to a spray dryer capable of avoiding bottom stacking. Background The spray dryer is used as a high-efficiency drying device and is widely applied to a plurality of industries such as chemical industry, medicine, food and the like. The working principle is that liquid materials are converted into fine mist particles and are subjected to rapid heat exchange with hot air, so that the materials are rapidly dried. However, in practical applications, the conventional spray dryer often has a problem of material accumulation at the discharge position, which not only affects the drying efficiency, but also may cause long-time retention of the material to cause deterioration, thereby affecting the product quality. Specifically, in the conventional spray dryer, the material is atomized and then enters a drying chamber to be contacted with hot air and dried. However, due to unreasonable design or improper operation of the discharge channel, the dried material tends to form a pile at the discharge site. The accumulation phenomenon not only prevents the smooth flow of the materials, and reduces the drying efficiency, but also can cause deterioration and even potential safety hazard because the materials stay in a high-temperature environment for a long time. In addition, the material is piled up and is still probably led to the fact adverse effect to spray drier's normal operating, and long-time piling up still can lead to the material hardening, thoroughly blocks up the discharge channel, needs to shut down the maintenance, seriously influences the operating efficiency of equipment. Disclosure of utility model In order to solve the above problems, embodiments of the present utility model provide a spray dryer capable of avoiding a stacking phenomenon. The embodiment of the utility model aims to achieve the aim, and particularly adopts the following technical scheme that the anti-stacking spray dryer comprises a spray dryer body, wherein a discharging assembly is arranged at the lower part of the spray dryer body and comprises a receiving hopper connected with the spray dryer body, a discharging channel is arranged at the lower part of the receiving hopper, an anti-blocking device for assisting discharging is arranged in the discharging channel, and a negative pressure suction pipe is arranged at the lower part of the discharging channel. As a further improvement of the above technical scheme: The anti-blocking device comprises a positioning ring plate arranged on the upper part of the discharging channel, a transmission shaft is arranged in the middle of the positioning ring plate, and the lower end of the transmission shaft extends to the outside of the receiving hopper to be connected with a driving source. A cross rod is arranged between the positioning ring plate and the transmission shaft, and a sealing bearing for connecting the cross rod is arranged in the middle of the transmission shaft. The outer side wall of the lower part of the transmission shaft is provided with a plurality of scattering blades, and the scattering blades are distributed along the height direction of the transmission shaft. The upper portion of transmission shaft is provided with the cleaning scraper blade with the lateral wall laminating of receiving hopper, be provided with the actuating arm of being connected with the transmission shaft on the cleaning scraper blade. The lower part of the driving arm is connected with the driving shaft, the upper part of the driving arm is provided with a sliding block which is in sliding connection with the receiving hopper, and the side wall of the receiving hopper is provided with an annular sliding rail which is matched with the sliding block for use. The upper portion of annular slide rail is provided with the locating plate of being connected with the lateral wall of receiving the hopper, annular slide rail is located the lower surface of locating plate. The anti-stacking spray dryer has the beneficial effects that 1, the anti-stacking spray dryer comprises a spray dryer body, the lower part of the spray dryer body is provided with a discharging assembly, the discharging assembly comprises a receiving hopper connected with the spray dryer body, the lower part of the receiving hopper is provided with a discharging channel, an anti-blocking device for assisting discharging is arranged in the discharging channel, materials in the discharging channel can be scattered by utilizing anti-blocking equipment, the phenomenon of excessive stacking of the materials is avoided, and the running stability and the production efficiency of the equipment are improved. 2.
