Abstract

An evaporator comprises a cylindrical shell, wherein, an agitating shaft is positioned in a center of the shell, a scraper frame is fixed on the agitating shaft, a scraper pressing spring device is fixed at an end of a scraper support, a scraper is fixed on the scraper pressing spring device by a bolt, an oscillation device is annularly covered on a rotation axis and fixed by a tension spring on an upper cover of the evaporator, a dust cover is arranged under an oscillator; a spray pipe is arranged at a position which is positioned at an upper in the shell, a lower of the agitating shaft is fixed with a discharge stirring blade, and the agitating shaft is driven by a motor. The utility model has simple structure and good evaporating effect. A fluid can sufficiently circulate in the evaporator. The utility model solves multiple defects existing in the prior evaporators, and can be widely used as an isolation and production device for various chemical solvents.

Description

Evaporimeter

The utility model relates to chemical industry equipment, particularly evaporation concentration equipment.

Be used for the evaporation equipment that the chemical industry separated from solvent is produced at present, kind is a lot, but all exist corresponding deficiency separately, more typical problem is that the raw material of evaporation is a kind of volatile substances that contains a certain amount of fine dust particle, if the excessive velocities of evaporation in evaporating course, indirect steam will be carried away a large amount of fine dusts secretly, bring adverse effect to follow-up equipment and product, simultaneously, material is in the process of evaporation and concentration, and along with the increase of viscosity, wall built-up, fouling occur, heat transfer efficiency is reduced, and addressing these problems becomes urgent need.

Task of the present utility model is: overcome the deficiencies in the prior art, design a kind of evaporated form that keeps the certain liq liquid level simple in structure, prevent the evaporimeter that fouling, liquid can fully circulate in evaporimeter.

The task of utility model realizes as follows: it has a columned housing evaporimeter, be positioned at the housing center shaft is housed, blade holder is fixed on the shaft, the scraper plate compression-spring device is fixed on the scraper stent end, scraper plate is by being bolted on the scraper plate compression-spring device, the oscillation device ring set is being fixed on the turning cylinder and by the extension spring on the evaporimeter upper cover, dust cover is housed below the oscillator, be positioned at the housing upper position shower is housed, the shaft bottom is fixed with the discharging paddle, and shaft is by driven by motor.The utility model compared with prior art has following advantage:

1, the liquid of evaporimeter is monitored by radar level gauge, and transmits control heating steam amount automatically, therefore can guarantee that evaporating liquid is constant

2, the startup of spray system is by the indirect steam pressure-controlled of evaporimeter inside, and when pressure reached capping, automatic spray cleaned Air Filter;

3,, can prevent from like this to stop up the valve leading portion when containing certain dust granules material limiting to discharge owing to the discharging paddle is housed in the axle lower end; Owing to below the housing internal oscillator dust cover is housed, the material that therefore can avoid evaporating is taken the dust of carrying secretly out of; Because the utility model is provided with shower and oscillator, can be used for therefore preventing that dust is affixed on online and discharge that stop up indirect steam.

Fig. 1 is the utility model front view;

A most preferred embodiment of the present utility model, as figure, it has a columned housing 6 evaporimeter, shaft 11 its lower ends that are positioned at the housing center are by graphite bearing 2 centering (or by suspension support centering), scraper stent 3 is fixed on the shaft 11, scraper plate compression-spring device 5 is fixed on the scraper stent end, scraper plate 4 is by being bolted on the scraper plate compression-spring device 5, oscillator 9 ring sets are being fixed on the turning cylinder and by the extension spring on the evaporimeter upper cover 10, Air Filter 7 is housed below the oscillator, be positioned at housing internal upper part position circular spray tube 8 is housed, the bottom of shaft is fixed with discharging paddle 1, and shaft is driven by decelerator by motor 12.The course of work of this device is: the rotation of driven by motor shaft, material in the housing in the process of evaporation and concentration along with the increase of viscosity, wall built-up, fouling are scraped by the spring scraper plate, have increased the circulation of fluid in evaporimeter like this, and the weak solution that is dissolved with solid-state dust granules is concentrated.In order to carry away a large amount of dust in the indirect steam that avoids evaporating secretly, the utility model is provided with the fiber dust removing net, in order to prevent that concentrating material stops up discharge gate, has installed paddle additional at discharge gate.

Claims

1, a kind of evaporimeter, it has a cylindrical housings, being positioned at the housing center has a shaft, and it is characterized in that: blade holder is fixed on the shaft, and the scraper plate compression-spring device is fixed on the scraper plate end, scraper plate is by being bolted on the scraper plate compression-spring device, the oscillation device ring set is being fixed on the turning cylinder and by the extension spring on the evaporimeter upper cover, dust cover is housed below the oscillator, is positioned at housing internal upper part position shower is housed, the shaft bottom is fixed with the discharging paddle, and shaft is by driven by motor.

2, evaporimeter as claimed in claim 1 is characterized in that: bearing is equipped with in its lower end of said shaft.
