When the device is used, the solvent is heated at a low speed and is heated unevenly, so that the urea dissolution speed is low.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

In order to solve the above problem of the prior art, the utility model provides a denitration urea dissolving tank for steam boiler, the rate of heating of solvent is very fast, the heating is even, can effectively promote the dissolving speed of urea.

(II) technical scheme

In order to achieve the above purpose, the utility model discloses a main technical scheme: including the axis of rotation that the motor, the vertical installation of jar body inner chamber top position are connected with motor drive, jar body inner chamber and lie in axis of rotation outside position and coil steam pipe, jar external wall fixed mounting's air heater, air pump and steam generator, the steam pipe coils into the frustum structure that the bottom opening is greater than open-top, spiral stirring vane is still installed to axis of rotation outer wall lower part position.

Preferably, jar body bottom is hemisphere structure, axis of rotation outer wall is close to bottom position still fixed mounting has the dead lever, the dead lever is kept away from axis of rotation one end and is still installed with jar arc scraper blade of body bottom adaptation.

Preferably, the bottom of the tank body is provided with a supporting leg.

Preferably, two fixing rods are installed.

Preferably, three fixing rods are installed.

(III) advantageous effects

The utility model provides a denitration urea dissolving tank for steam boiler. The method has the following beneficial effects:

(1) the motor drives the rotating shaft to rotate, the spiral stirring blades are driven to continuously spray the solvent and the solute at the bottom of the inner cavity of the tank body upwards from the middle, the solvent with lower bottom temperature is continuously heated by being contacted with a steam pipe coiled into a frustum structure when being sprayed, the heating efficiency is higher, and the dissolving speed of the solute is higher.

(2) The rotating shaft driven by the motor drives the arc-shaped scraper, continuously scrapes the solute precipitated at the bottom of the tank body, and the solute is prevented from being accumulated at the bottom by being dissolved in cooperation with the accelerator of the spiral stirring blade.

Drawings

Fig. 1 is a front sectional view of the present invention.

In the figure: 1. a tank body; 2. a motor; 3. a rotating shaft; 4. a steam pipe; 5. an air heater; 6. an air pump; 7. a steam generator; 8. a helical mixing blade; 9. fixing the rod; 10. an arc-shaped scraper plate; 11. and (5) supporting legs.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, the denitration urea dissolving tank for the steam boiler of the embodiment includes a tank body 1, a motor 2 at the top position of an inner cavity of the tank body 1, a rotating shaft 3 vertically installed in the inner cavity of the tank body 1 and connected with the motor 2 in a transmission manner, a steam pipe 4 coiled in the inner cavity of the tank body 1 and located outside the rotating shaft 3, an air heater 5 fixedly installed on the outer wall of the tank body 1, an air pump 6 and a steam generator 7, wherein the steam pipe 4 is coiled into a frustum structure with a bottom opening larger than a top opening, and a spiral stirring blade 8 is further installed at the lower position of the outer wall of the rotating shaft 3. The motor 2 drives the 3 pivoted in-processes of axis of rotation, drives that the spiral stirring vane 8 is continuous to be spout the solvent and the solute of 1 inner chamber bottom of jar body continuously from the middle upwards, and the lower solvent of bottom temperature can be continuous and coil into the steam pipe 4 contact heating of frustum structure when spouting last, and heating efficiency is higher, and the solution rate of solute is faster.

Further, jar body 1 bottom is hemisphere structure, and 3 outer walls of axis of rotation are close to bottom position still fixed mounting have dead lever 9, and dead lever 9 keeps away from 3 one ends of axis of rotation and still installs the arc scraper blade 10 with jar body 1 bottom adaptation. Through axis of rotation 3 that motor 2 drove, drive arc scraper blade 10, the solute that the continuous 1 bottom of scraping jar body precipitated, cooperation spiral stirring vane 8 accelerator dissolves, avoids the solute to pile up in the bottom.
