Description

Technical Field

[0001] The utility model relates to the technical field of slow and controlled release fertilizer production and processing, and particularly relates to a spraying device for producing slow and controlled release fertilizers. Background Art

[0002] One of the common production and processing methods of slow and controlled release fertilizers is to coat a semi-permeable or poorly soluble coating on the surface of water-soluble fertilizer particles, so that the coated water-soluble fertilizer particles have the characteristic of slowly releasing nutrients.

[0003] In order to enable the coating material to be evenly coated on the surface of the fertilizer particles, the coating material is usually dissolved in a solvent; then, while stirring the fertilizer particles, the solvent dissolved with the coating material is sprayed. While stirring, the fertilizer particles are heated to dry the solvent, and the coating material can be left on the surface of the fertilizer particles.

[0004] During actual production, slow and controlled release fertilizers are often produced in batches at regular intervals; the nozzle for spraying the solvent is prone to clogging due to the drying of the residual coating material after the solvent volatilizes or evaporates; the fertilizer particles are usually put into a horizontally placed stirring tank for stirring, and the volume of the stirring tank is relatively large, making it very inconvenient to clean the nozzle in the stirring tank. Summary of the Invention

[0030] An embodiment of the present utility model provides a spraying device for producing sustained-release fertilizers. The spraying device includes: a liquid storage tank 1, a spray pipe 2 detachably connected to the liquid storage tank 1, and a power source for driving the solvent to flow from the liquid storage tank 1 to the spray pipe 2. It should be understood that, according to the requirements of the actual situation, sometimes multiple liquid storage tanks 1 can be provided and multiple spray pipes 2 can be correspondingly adapted. The liquid storage tank 1 is provided with a feed inlet and is adapted to a feed valve 3. It should be understood that by opening the feed valve 3, the solvent dissolved with the coating material can be supplemented into the liquid storage tank 1.

The sub-pipe 4 is provided with a nozzle 6.

[0031] The following describes the specific implementation manner of the present utility model: This spraying device is usually used in cooperation with a horizontal stirring tank, and the spray pipe 2 extends into the stirring tank along the length direction of the stirring tank. When the stirring tank tumbles the fertilizer particles, the power source is used to send the solvent dissolved with the coating material in the liquid storage tank 1 to the spray pipe 2; a plurality of nozzles 6 distributed along the length direction of the spray pipe 2 can spray the solvent dissolved with the coating material in each area in the length direction of the stirring tank. After the spraying device finishes working, the spray pipe 2 is removed and withdrawn from the stirring tank; for each section withdrawn, the outermost sub-pipe 4 is screwed and removed; in this way, each sub-pipe 4 can be taken out and washed. After the washing is completed, the spray pipe 2 is sent into the stirring tank again; for each section sent in, a section of sub-pipe 4 is connected to the outer end; finally, the outer end of the spray pipe 2 is connected to the liquid storage tank 1.

[0035] Further, the first interface 7 is provided with external threads and is communicated with the outlet of the air supply pipe network 10 through a first connecting pipe 12. It should be understood that the first connecting pipe 12 can be a common commercially available connecting hose, the main body part of which can be bent, and the two ends are respectively sleeved with rotatable internal thread joints, and sealing rings are provided inside the joints.

[0036] Further, the second interface 8 is provided with external threads and is communicated with a liquid delivery pipe 14 through a second connecting pipe 13; the liquid delivery pipe 14 is provided with a liquid delivery valve 15 and is communicated with the spray pipe 2. It should be understood that the second connecting pipe 13 can be a common commercially available connecting hose, the main body part of which can be bent, and the two ends are respectively sleeved with rotatable internal thread joints, and sealing rings are provided inside the joints. The two ends of the liquid delivery pipe 14 are respectively threadedly connected with the connecting pipe and the spray pipe 2.

[0037] Further, a bracket 16 is further included; the bracket 16 includes: a base, a support table, a vertical rod connecting the base and the support table, and a pressing member for pressing the liquid delivery pipe 14 on the support table; the pressing member is detachably connected to the support table. It should be understood that the base can be fixed to the ground or a base through bolts to more stably support the liquid delivery pipe 14 and the spray pipe 2. The vertical rod can be set as a hollow rod.
