Description

Technical Field

[0001] The utility model relates to the field of industrial equipment, in particular to a dissolving device for producing water-soluble fertilizers. Background Art

[0002] Water-soluble fertilizers are complex, fully soluble complex fertilizers that dissolve quickly and are easily absorbed by crops. Compared to traditional superphosphate and granulated compound fertilizers, water-soluble fertilizers offer significant advantages, including reduced dosage, ease of use, low cost, rapid crop absorption, and high nutrient utilization.

[0003] When producing water-soluble fertilizers, the raw materials need to be dissolved and then the water-soluble fertilizers are prepared. However, after the solid raw materials enter the dissolution tank, they are not dissolved in time and accumulate at the bottom of the tank, resulting in precipitation. The conventional method is to add a rotating brush at the bottom of the dissolution tank to scrape up the sediment. However, some flocculent sediments can adhere to the brush body and deteriorate and clump over time. As the use time increases, the sedimentation accumulation increases, thereby affecting the production efficiency of the water-soluble fertilizer. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a dissolving device for producing water-soluble fertilizers that can prevent precipitation and accumulation and improve dissolution efficiency.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is a dissolving device for producing water-soluble fertilizers, comprising a feed pipe, a dissolving tank and a liquid outlet pipe, wherein the feed pipe is connected to the top of the dissolving tank and the liquid outlet pipe is connected to the bottom of the dissolving tank;

[0006] The dissolving tank is a tank-shaped structure with an upper cylindrical portion and a lower funnel portion. The bottom of the dissolving tank is connected to a backflush pipe, which can impact the fluid from the bottom of the dissolving tank into the interior of the dissolving tank.

[0007] A booster pump and a one-way valve are provided on the backwash pipe, and the one-way valve is located on the backwash pipe between the booster pump and the dissolution tank.

[0008] The beneficial effects of the above technical solution are: after the raw materials enter the dissolution tank, the sediment that has not been fully dissolved cannot accumulate at the bottom of the tank under the action of the backwash pipe. At the same time, the fluid in the backwash pipe entering the dissolution tank can further stir the liquid flow direction of the dissolution tank, thereby helping the raw materials to be fully dissolved; the structure of the upper cylinder and the lower funnel of the dissolution tank can gather the sediment, thereby facilitating the fluid flushing of the backwash pipe, so that the fluid flushed by the backwash pipe can affect the entire dissolution tank from point to surface; the booster pump can increase the impact force of the fluid in the backwash pipe on the dissolution tank; the one-way valve limits the flow direction of the fluid from the backwash pipe into the dissolution tank, preventing undissolved sediment from entering the backwash pipe.

[0009] Furthermore, a drain valve is provided at the bottom of the dissolving tank, and the drain valve is provided on a backflush pipe between the one-way valve and the dissolving tank.

[0010] Beneficial effect: providing a sewage discharge path for the dissolving tank, and preventing impurities from entering the backwash pipe during sewage discharge, thereby damaging the booster pump.

[0011] Furthermore, a rotating shaft is rotatably arranged inside the dissolving tank, the rotating shaft is arranged vertically, a stirring rod is fixed on the rotating shaft in the horizontal direction, a stirring motor is fixed above the dissolving tank, and the rotating shaft extends out of the dissolving tank and is transmission-connected to the stirring motor.

[0012] Beneficial effect: The raw materials are fully contacted with the liquid, thereby improving the dissolution efficiency of the raw materials.

[0013] Furthermore, the pipe opening of the backflushing pipe connected to the dissolving tank is located on the bottom plate inside the dissolving tank, and the position does not interfere with the rotating shaft.

[0014] Beneficial effects: on the one hand, the stability of the rotating connection of the shaft is ensured; on the other hand, the flushing effect of the fluid in the backflushing pipe on the dissolving tank is ensured, so that it acts on the sediment from the bottom first.

[0015] Furthermore, the stirring rod is provided with stirring blades, and a plurality of groups of stirring blades are staggered and distributed on the upper and lower sides of the stirring rod.

[0016] Beneficial effect: Expand the stirring range of the stirring rod on the solution and improve the stirring effect.

[0017] Furthermore, a filter plate is provided in the dissolving tank, the filter plate surrounds the outer side of the stirring rod and the upper and lower ends of the filter plate are fixed on the tank wall of the dissolving tank.

[0018] Beneficial effect: The filter plate can block the incompletely dissolved raw materials in the stirring area, and the incompletely dissolved raw materials continue to be stirred and dissolved in the inner area of ​​the filter plate, and the dissolved liquid flows out of the liquid outlet pipe through the filter plate.

[0019] Furthermore, the feed pipe is connected from the top of the dissolving tank to the inner area surrounded by the filter plate; the liquid outlet pipe is connected to the outside of the area surrounded by the filter plate.

[0020] Beneficial effect: Prevents incompletely dissolved raw materials from flowing out of the liquid outlet pipe directly, ensuring that the raw materials can be fully dissolved.

[0021] Furthermore, an observation port is provided on the top of the dissolving tank.

[0026] The following is a further detailed description of a dissolving device for producing water-soluble fertilizers according to the present invention in conjunction with the accompanying drawings and specific embodiments.

[0027] like Figure 1-2 As shown, the utility model is a dissolving device for producing water-soluble fertilizers, comprising a feed pipe 1, a dissolving tank 2 and a liquid outlet pipe 3. The feed pipe 1 is connected to the top of the dissolving tank 2, and the liquid outlet pipe 3 is connected to the bottom of the dissolving tank 2. The dissolving tank 2 is a tank-shaped structure with an upper cylinder and a lower funnel. The bottom of the dissolving tank 2 is connected to a recoil pipe 4. The recoil pipe 4 can impact the fluid from the bottom of the dissolving tank 2 into the inside of the dissolving tank 2. A booster pump 5 and a one-way valve 6 are provided on the recoil pipe 4. The one-way valve 6 is located on the recoil pipe 4 between the booster pump 5 and the dissolving tank 2. The fluid inside the recoil pipe 4 impacts the sediment from the bottom of the dissolving tank 2 to prevent the sediment from accumulating at the bottom of the tank. At the same time, the entire dissolving tank 2 is stirred with the help of the impact force of the fluid, which helps to fully dissolve the raw materials and improve the production efficiency of the water-soluble fertilizer.

[0028] In this embodiment, a drain valve 7 is provided at the bottom of the dissolving tank 2 to provide a drainage path for the dissolving tank 2. The drain valve 7 is provided on the backflush pipe 4 between the one-way valve 6 and the dissolving tank 2. During the dissolving process, the drain valve 7 is closed, and the booster pump 5 drives the fluid directly into the dissolving tank 2 to impact the sediment inside; when the dissolution is completed, the booster pump 5 is closed and the drain valve 7 is opened. At the same time, the one-way valve 6 below can prevent backflow, and the internal impurities are discharged from the drain valve 7 to prevent impurities from entering the backflush pipe 4 during drainage, thereby damaging the booster pump 5; further, the drain valve 7 can facilitate equipment maintenance.
