Description

TECHNICAL FIELD

[0001] The utility model relates to drying tower technical field, concretely is a kind of spray drying tower. BACKGROUND

[0002] Spray drying tower is a kind of equipment using spray technology to rapidly dry liquid material (such as solution, emulsion, suspension, etc.) into powder, granular or hollow spherical solid product. It combines atomization, drying and separation processes, and is widely used in food, chemical, pharmaceutical, ceramic, environmental protection and other industries. The core of spray drying tower is to disperse liquid material into small droplets through an atomizer (such as pressure type, centrifugal type or air flow type). These droplets are in full contact with high-temperature hot air (or hot air) in the drying tower, which causes rapid heat and mass transfer, and the water in the droplets evaporates rapidly, finally forming dry solid particles.

[0003] However, the existing drying tower has the problem of particle adsorption on the inner surface of the drying tower. This situation can form a heat insulation layer, which hinders the full heat exchange between hot air and material, and also increases the subsequent cleaning time and cost. Therefore, in order to solve this problem, Chinese patent CN220860664U proposes a spray drying tower, which starts the driving motor, and the driving motor provides power to the driving gear through the rotating output end. Since the driving gear is drivenly connected to the driven gear through a transmission belt, the driving gear transmits power to the driven gear through the transmission belt. The driven gear rotates the rotating shaft and cam. When the cam rotates, it hits the fixed block. When the cam contacts the fixed block, the extension rod and the extension spring are compressed. The connecting rod and the hammer do not contact the outer wall of the drying tower body. When the cam moves away from the fixed block, the hammer hits the drying tower body under the elastic action of the extension spring. During the hammering process, the drying tower body moves within the moving range under the cooperation of the compression spring and the slide rod. This method can indeed solve the above problems, but it still has some shortcomings. The shaking amplitude needs to be as large as possible, and the frequency should be high. This method cannot effectively clean, so the degree of improvement cannot be effectively improved.

[0004] According to the above, in order to prevent the subsequent cleaning difficulty and hinder the full exchange between hot air and material caused by particle adsorption on the inner surface of the drying tower, a spray drying tower is proposed to solve the above technical problems.
