Description

Technical Field

[0001] The utility model belongs to the technical field of fertilizer production, and in particular relates to a cooling device for fertilizer preparation. Background Art

[0002] Chemical fertilizers are fertilizers made by chemical and / or physical methods that contain one or more nutrients required for the growth of crops. They are also called inorganic fertilizers and include nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, trace fertilizers, compound fertilizers, etc. They are not edible.

[0003] At present, cooling treatment is required in the production and processing of fertilizers, but the existing fertilizer cooling equipment usually relies on water cooling for heat absorption cooling, which consumes a lot of water resources. In addition, since the internal body is not turned over thoroughly enough, most of the fertilizers cannot contact the cooling pipes, resulting in slow temperature transmission between the fertilizers, which in turn causes the cooling time to be too long. At the same time, the loading and unloading of materials before and after cooling is not fast enough, resulting in low overall production efficiency and quality, which needs to be improved. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a cooling device for fertilizer preparation, which can achieve more comprehensive and efficient air cooling treatment of fertilizers and can quickly load and unload materials before and after cooling to solve the above problems.

[0005] To achieve the above-mentioned purpose, the technical scheme adopted by the utility model is: a cooling device for fertilizer preparation, comprising an air cooler, an air pump and a cooling trough, the air outlet of the air cooler is connected to the air inlet of the air pump, the bottom of the cooling trough is penetrated by a fixed air inlet pipe, the bottom end of the air inlet pipe is connected to the air outlet of the air pump, and the top end is connected to a horizontally arranged hollow air distribution plate, annular guide rails are fixed on the left and right inner walls of the cooling trough, electric sliders are slidably arranged on the two guide rails, mounting blocks are fixedly connected on the opposite sides of the two electric sliders, positioning grooves are provided on the tops of the two mounting blocks, and a plurality of blind holes distributed in a rectangular array are provided on the opposite sides of the two mounting blocks, a barrel is provided between the two mounting blocks, the barrel is coaxially arranged with the guide rail, and its barrel wall is mesh-shaped and its longitudinal cross-section is annular, electric push rods are fixedly arranged on the upper parts of the left and right outer end walls of the barrel, and the two electric push rods are fixedly arranged on the upper parts of the two electric push rods. The telescopic ends of the movable push rods are arranged back to back and are fixedly connected with fixing plates, and a plurality of fixing rods are fixedly provided on the opposite sides of the two fixing plates, and an inverted L-shaped positioning plate is fixedly provided on the outer end wall of the barrel above the two electric push rods, and the vertical parts of the positioning plate are inserted in the positioning grooves of the mounting blocks on the same side, and the fixing plates abut against the mounting blocks on the same side, and the fixing rods correspond to and are inserted into the blind holes on the same side one by one, and a material pipe with a gate valve is connected to the lower part of the end wall of the barrel, and hydraulic cylinders are horizontally fixedly mounted on the left and right outer walls of the cooling groove, and the piston rods of the two hydraulic cylinders are relatively arranged and fixedly connected with air distribution pipes, and the two air distribution pipes are connected with the air inlet pipe through hoses, and a plurality of nozzles are connected on the circumference of the two air distribution pipes and the top of the air distribution plate. The air distribution pipe is coaxially arranged with the guide rail and has a through hole on the corresponding side wall of the cooling groove, and the air distribution pipe can extend into the inner side of the barrel through the through hole.

[0006] Preferably, the positioning plate is matched with the corresponding positioning groove.

[0007] Preferably, the fixing rod is matched with the corresponding blind hole.

[0010] The beneficial effects of the utility model are as follows: before cooling, multiple barrels can be prepared in advance, and the fertilizer to be cooled can be divided into each barrel through the material pipe. After the division, the gate valve is closed. During cooling, first adjust the two electric sliders to the upper part of the guide rail, then take a barrel filled with materials and send it into the cooling tank until the positioning plates on both ends of the barrel are inserted into the corresponding positioning grooves, so that the initial positioning and installation of the barrel can be achieved. Then, operate the two electric push rods to extend their telescopic ends, drive the fixed plate to move until it presses against the corresponding mounting block, and the fixed rod at this time can be inserted into the corresponding blind hole, and the mounting block is inserted and fixed, so that the barrel can be further fixed and installed, and the installation is stable and does not affect subsequent operations.

The overall cooling efficiency is higher, the effect is better, and the cooling is more uniform and complete, which can greatly improve the overall production efficiency and quality;

[0011] After cooling, turn off the air cooler and air pump, stop the input of cold air, adjust the electric slider to the upper part of the guide rail, turn off the electric slider, and stop the rotation of the barrel. Then, run the two electric push rods again to shrink the telescopic ends, drive the two fixed plates back, until the fixed rods are completely withdrawn from the corresponding blind holes, and then the plug-in fixation of the mounting block can be released. Then pull out the positioning plate, and the barrel can be removed and moved out of the cooling tank. After that, replace it with another loaded barrel as mentioned above, and continue cooling. By opening the gate valve on the cooled barrel, the cooled fertilizer material can be discharged. In this way, the batch loading and unloading of fertilizers can be realized by quickly disassembling and replacing the entire barrel before and after cooling, which can further improve efficiency and be more conducive to overall production and processing.
