Description

Technical Field

[0001] This utility model belongs to the field of water-soluble fertilizer production technology, and specifically relates to a reaction vessel for producing water-soluble fertilizer. Background Technology

[0002] A reaction vessel for producing water-soluble fertilizer is a specialized device used to mix, heat, and stir raw materials for water-soluble fertilizer. This equipment involves adding raw materials for water-soluble fertilizer (such as urea, monoammonium phosphate, potassium sulfate, etc.) into the reaction vessel, then heating and stirring to induce a chemical reaction, ultimately producing water-soluble fertilizer.

[0003] Existing reactors for producing water-soluble fertilizers involve adding the raw materials into the reactor, heating them to induce a reaction, and stirring to increase the reaction rate. However, when granular or powdered materials are added to the reactor, they are prone to clumping in humid environments. Clumped materials are difficult to disperse evenly in the reactor, leading to incomplete reactions, affecting the quality and purity of the product. The clumped material can also generate hot spots due to uneven heat transfer, causing localized overheating or even sintering, damaging the equipment and creating safety hazards. Furthermore, it reduces the effective reaction area, thereby lowering the overall reaction rate and efficiency. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a reaction vessel for producing water-soluble fertilizer, which is equipped with a dispersing mechanism to disperse granular or powdered raw materials, ensuring that each particle can fully participate in the reaction, improving product uniformity, and the fine and uniform distribution of raw materials is conducive to the transfer of heat and matter, accelerating the reaction speed, improving efficiency, reducing blockage and local overheating caused by agglomeration, and protecting the reaction vessel and related equipment from damage.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a reaction vessel for producing water-soluble fertilizer includes a support frame, a heating tank is arranged inside the support frame, a feed pipe is arranged in the feed hole on the right side of the outer arc surface of the heating tank, a discharge pipe is arranged in the discharge hole at the lower end of the heating tank, a solenoid valve is connected in series in the middle of the discharge pipe, a feed box is arranged at the feed inlet at the upper end of the heating tank, a cover plate is hinged to the upper end of the feed box, a reaction stirring mechanism is arranged inside the heating tank, a raw material dispersing mechanism is arranged inside the feed box, the reaction stirring mechanism includes a stirring column arranged inside the heating tank, a plurality of evenly distributed stirring blades are arranged on the outer arc surface of the stirring column, and the lower end of the stirring column... A scraper frame is provided, and the stirring support and the scraper frame are fixed by welding. The scraper frame is in contact with the inner arc wall of the heating tank. An electric drive unit one for driving the stirring column to rotate is provided at the upper end of the heating tank. The electric drive unit one includes a motor one provided at the upper end of the heating tank. The output shaft of motor one is connected to the upper end of the stirring column through a coupling. The raw material dispersing mechanism includes a rotating column rotatably provided inside the feed box. Multiple dispersing blades are provided on the outer arc surface of the rotating column. The rotating column and the dispersing blades are fixed by welding. An electric drive unit two for driving the rotating column to rotate is provided at the left end of the feed box. The electric drive unit two includes a motor two provided at the left end of the feed box. The output shaft of motor two is connected to the left end of the rotating column through a coupling.

[0006] As a further improvement of this utility model, the support frame is equipped with a control panel, and the motor one, heating tank, motor two and solenoid valve are all electrically connected to the control panel.

[0007] As a further improvement of this utility model, multiple support mounting plates are welded and fixed to the lower end of the support frame. The support mounting plates and the support frame are fixed by welding, and multiple mounting holes are opened inside the two support mounting plates.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] Firstly, the heating tank is opened and preheated. Then, liquid raw materials are added into the heating tank through the feed pipe. After that, the cover is opened and granular raw materials are added into the heating tank through the feed box. The cover is then closed. Once the motor is started, the output shaft drives the stirring blades on the stirring column to stir the raw materials inside, thereby increasing the reaction efficiency. During the stirring reaction, the cover effectively prevents the raw materials from overflowing. After the reaction is completed, the solenoid valve is opened to allow the water-soluble fertilizer to be continuously discharged from the discharge pipe, which can quickly complete the reaction of the water-soluble fertilizer.

[0010] Secondly, when the stirring column rotates, the scraper at its lower end can scrape off the raw materials adhering to the inner wall of the heating tank and continue the stirring reaction, making it easier for personnel to use.

[0011] Thirdly, by controlling the operation of motor II, the output shaft drives the dispersing blades on the rotating column to disperse the agglomerated raw materials, thereby improving the efficiency of subsequent stirring and reaction. The dispersing mechanism is set up to disperse granular or powdery raw materials, ensuring that each particle can fully participate in the reaction, improving product uniformity. The fine and uniform distribution of raw materials is conducive to the transfer of heat and matter, accelerating the reaction speed, improving efficiency, reducing blockage and local overheating caused by agglomeration, and protecting the reactor and related equipment from damage.

[0012] Fourth, the lower support plate can provide stable support for the reactor vessel, while the internal mounting holes can quickly fix the reactor vessel in place, preventing it from shifting during operation and making its operation more stable. Attached Figure Description

Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

The electric drive unit 2 includes a motor 201 disposed at the left end of the feed box 105. The output shaft of the motor 201 is connected to the left end of the rotating column 202 through a coupling.

[0021] like Figure 1 , 2 As shown in Figure 4, the reaction stirring mechanism includes a stirring column 108 disposed inside the heating tank 102. Multiple uniformly distributed stirring blades 109 are disposed on the outer arc surface of the stirring column 108. A scraper frame 110 is disposed at the lower end of the stirring column 108. The scraper frame 110 is in contact with the inner arc wall of the heating tank 102. An electric drive unit 1 is disposed at the upper end of the heating tank 102 to drive the stirring column 108 to rotate. The electric drive unit 1 includes a motor 104 disposed at the upper end of the heating tank 102.
