Embodiment Construction

[0040] Such as Figure 1-7 As shown, the horizontal conical thin-film evaporator of this embodiment includes a frame base 1 as a support, a driving component 2 arranged on the frame base 1 to realize drive control, and a jacket 3 arranged on the frame base 1 as The outer support, the conical evaporation chamber 4 lying in the jacket 3 is used as the inner sleeve, and the taper is used to realize the gathering of the materials during the transmission, so as to realize the concentrated heating of the materials by the accumulation of heat. The heat flow interlayer channel 5 between the chambers 4 realizes the flow heating of the heat flow (hot air flow or hot liquid), and rotates the rotor 6 arranged in the conical evaporation chamber 4 and communicated with the driving part 2, and the rotor 6 is provided with wings The sheet realizes that the material moves forward during agitation.

[0041] The conical evaporation chamber 4 is divided into rear steam chamber 27, middle steam c...

Abstract

The invention relates to a horizontal conical film evaporator. The evaporator comprises a rack base, a driving part arranged on the rack base, a jacket arranged on the rack base, a conical evaporationchamber horizontally arranged in the jacket, a heat flow interlayer channel arranged between the jacket and the conical evaporation chamber, and a rotor which is rotationally arranged in the conicalevaporation chamber and is in transmission connection with the driving part, and fins are arranged on the rotor. The conical evaporation chamber is divided into a rear steam cavity, a middle steam cavity and a front steam cavity from the large end to the small end from left to right. The upper end of the rear steam cavity is provided with a material inlet used for adding materials, the upper end of the large end face of the rear steam cavity is provided with a tail end steam inlet / hot liquid outlet, and the right side of the material inlet is provided with a material return port used for returning materials in steam; the device is reasonable in design, compact in structure and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of concentration equipment, and relates to a horizontal conical thin-film evaporator. Handling of viscous products. Background technique [0002] At present, the rotary thin film evaporator is a high-efficiency evaporator that forms a film forcibly through a rotating scraper and can evaporate under vacuum conditions. It has a large heat transfer coefficient, high evaporation intensity, and large operating flexibility. It is especially suitable for suspensions and pastes. Drying of solid materials and evaporation concentration, precipitation and distillation of easily crystallized granular materials. Therefore, it is widely used in chemical, pharmaceutical, pesticide and other industries. Most of the rotary thin film evaporators in the prior art are vertical, and the flow rate of the raw material liquid in the evaporator cylinder is relatively fast, resulting in insufficient evaporation of light components,...
