Horizontal film evaporator

Abstract

The invention belongs to the technical field of concentration equipment, and relates to a horizontal film evaporator. The evaporator is suitable for the concentration of dilute solution in the pharmacy, food and chemical industry, and especially suitable for the concentration of a thermosensitive product. The main body structure of the horizontal film evaporator comprises a motor, a speed reducer, a belt, a bearing, a mechanical sealing element, a medium inlet, a pressure transmitter, a vacuum port, a temperature transmitter, a swing bolt, a movable end socket, a cleaning spraying ball, a sight glass, a medium outlet, a discharge port, a support plate, an arc-shaped scraper plate, a feed port, a base, a first landing leg, a second landing leg, a rotating shaft, an insulating layer, a speed reducer support, a heating tank body, a motor fixing seat, a heating jacket and an evaporation chamber; the sealing between the tank body and the tank body is the container type dual-end face mechanical sealing; the equipment driver is connected with the motor through a belt pulley of the speed reducer, the speed reducer is connected with a mixing shaft through the belt pulley, the working vibration is small, and the running is stable; the entire structure is simple in principle, safe and reliable in performance, high in concentration effect and friendly to application environment.

Description

Technical field: [0001] The invention belongs to the technical field of concentrating equipment, and relates to a horizontal thin film evaporator, which is suitable for concentrating dilute solutions in pharmaceutical, food, chemical and other industries, especially for concentrating heat-sensitive products. Background technique: [0002] In the field of pharmaceuticals and food, many products need to be concentrated and dried after preparation, and the general artificial static drying and heating evaporation have been eliminated by the market; due to the inherent properties of medicines and food, it is not suitable for open concentration methods, so as to prevent the products from being unsuitable. Necessary pollution; at present, the main equipment used for material concentration on the market is the concentration tank and vertical thin film evaporator. The concentration tank is suitable for small batch and batch production, and cannot be used for continuous production. Fo...

[0002] In the field of pharmaceuticals and food, many products need to be concentrated and dried after preparation, and the general artificial static drying and heating evaporation have been eliminated by the market; due to the inherent properties of medicines and food, it is not suitable for open concentration methods, so as to avoid the products from being unsuitable. Necessary pollution; at present, the main equipment used for material concentration on the market is concentration tank and vertical thin film evaporator. The concentration tank is suitable for small batch and batch production, and cannot be used for continuous production. For large manufacturers, it cannot solve the problem of production efficiency; the vertical thin film evaporator has improved the production efficiency compared with the concentration tank, but the volume of the vertical thin film evaporator is too large, and the installation height, installation environment requirements and installation The site requirements are relatively high, the preparation and installation costs are high, and the vertical thin film evaporator is not easy to clean, and the later maintenance costs are high

Chinese patent 201610311048.3 discloses a steam-heated multi-layer thin film evaporator. This device is limited to steam as the heating medium, and has few application scenarios. The number of layers of the device is complex and the structure is complicated. Although the heating area is increased, the heating temperature becomes lower. , is not conducive to the heating and concentration of materials, and the concentration effect is poor
