Description

Technical Field

[0001] This utility model relates to the field of high-tower compound fertilizer production equipment, and in particular to high-tower compound fertilizer production equipment. Background Technology

[0002] The high-tower compound fertilizer production unit is an important piece of equipment used to produce high-concentration compound fertilizers. Its core lies in the use of melt granulation technology, which melts raw materials such as nitrogen, phosphorus, and potassium at high temperatures and then sprays them into granules at the top of the high tower through specific nozzles.

[0003] During the production and processing of compound fertilizer using a high-tower press, in order to increase the uniformity and nutrient content of fertilizer particles, a secondary spraying system may be used to coat the particles. If the spraying is uneven or excessive, powder may adhere to the surface of the fertilizer particles. When the processed fertilizer particles are discharged from the discharge pipe, the excess fertilizer powder will be discharged along with the fertilizer particles, resulting in fertilizer powder waste, increasing the company's costs, and reducing the practicality of the high-tower press. Utility Model Content

[0004] The technical problem this invention aims to solve is as follows: During the production and processing of compound fertilizer using a high-tower production machine, in order to increase the uniformity and nutrient content of fertilizer particles, a secondary spraying system may be used to coat the particles. If the spraying is uneven or excessive, powder may adhere to the surface of the fertilizer particles. When the processed fertilizer particles are discharged from the discharge pipe, the excess fertilizer powder will be discharged along with the fertilizer particles, resulting in fertilizer powder waste, increasing the company's costs, and reducing the practicality of the high-tower production machine.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a high-tower compound fertilizer production device, including a high-tower production machine, wherein a granulation disc is provided inside the high-tower production machine, and a filtration device is provided at the outlet of the granulation disc. The filtration device includes a filter barrel and a filter screen, and a replacement device is provided between the filter barrel and the filter screen. The filtration device can filter the fertilizer granules processed by the granulation disc and filter off the excess fertilizer powder attached to their surface. The replacement device can facilitate the cleaning, maintenance and replacement of the surface of the filter screen.

[0006] Preferably, the inlet on one side of the filter barrel is fixedly connected to the outlet of the granulation disc, a first discharge pipe is symmetrically connected to the outer surface of the filter barrel, a second discharge pipe is connected to the outer surface of the filter barrel between the two first discharge pipes, a solenoid valve plate is provided on the inner wall of each of the two first discharge pipes, an impeller is connected to the inner wall of the filter barrel, a motor is fixedly connected to one end of the impeller, one side of the motor is fixedly connected to one side of the filter barrel, and the filter screen is located at the second discharge pipe.

[0007] The effect achieved by the above components is as follows: By setting up a filtration device, when fertilizer granules are formed in the granulation disc and discharged from the outlet, they fall into the filter barrel. Then, the motor is started to drive the impeller to rotate inside the filter barrel, so that the compound fertilizer granules falling into the filter barrel can fully contact the surface of the filter screen at the second discharge pipe. This allows the excess fertilizer powder adhering to the surface of the granules to be filtered off and discharged from the second discharge pipe. The granules then fall onto the conveying mechanism inside the tower press and are transported out. After filtering for a period of time, the solenoid valve plate in the first discharge pipe can be opened periodically, so that the impeller rotates to a certain position and discharges the filtered compound fertilizer granules from the first discharge pipe. The granules then fall onto the conveying mechanism inside the tower press and are transported to the next processing stage. This operation can filter off the excess fertilizer powder adhering to the surface of the compound fertilizer granules, making it convenient for later use, avoiding waste of fertilizer powder, reducing enterprise costs, and improving the practicality of the tower press.

[0008] Preferably, a circular roller is rotatably connected to the inner wall of one end of the impeller blades, and the outer surface of the circular roller is in rolling connection with the inner wall of the filter barrel.

[0009] The effect achieved by the above components is that by setting up the circular roller, the contact wear between the impeller blades and the filter barrel can be reduced, which facilitates the rotation of the impeller, reduces the damage to the impeller, and improves its service life.

[0010] Preferably, a protective cover is fixedly connected to one side of the filter barrel, and the motor is located inside the protective cover.

[0011] The effect achieved by the above-mentioned components is that by setting up a protective cover, the outer surface of the motor can be covered, increasing the hardness of the motor surface and preventing damage.

The filter screen is inserted into the inner wall of the mounting hole. An electric telescopic rod is fixedly connected to one side of the filter barrel, and the output rod of the electric telescopic rod is fixedly connected to one side of the mounting frame.

[0015] The effect achieved by the above components is as follows: by setting up an easy replacement device, when it is necessary to clean or replace the filter screen, the electric telescopic rod can be activated to drive the mounting bracket to slide outward in the inner wall of the sliding hole, thereby sliding the filter screen out of the filter barrel, which is convenient for surface maintenance and cleaning, or removing it from the mounting hole for easy replacement, thereby improving the filtration effect of the filtration device and facilitating its maintenance.

[0016] Preferably, the outer surface of the output rod of the electric telescopic rod is symmetrically fixedly connected with reinforcing rods, and one side of the reinforcing rod is fixedly connected to one side of the mounting frame.

[0017] The effect achieved by the above components is that by setting up reinforcing rods, the connection area between the electric telescopic rod and the mounting frame can be increased, making the connection more secure and stable.

[0018] Preferably, magnets are fixedly connected to both sides of the filter screen, the mounting bracket is made of iron, and one side of the magnet is magnetically attracted to one side of the inner wall of the mounting hole.

[0019] The effect achieved by the above components is as follows: by setting up a magnetic block, and then clamping the filter screen in the inner wall of the mounting hole, the magnetic block on one side will be attracted to the inner wall of the mounting hole, limiting the position of the filter screen and making it less likely to shake.

[0020] The beneficial effects of this utility model are:

[0021] By setting up a filtration device, after the fertilizer granules are formed in the granulation disc and discharged from the outlet, they fall into the filter barrel. Then, the motor is started to drive the impeller to rotate inside the filter barrel, so that the compound fertilizer granules falling into the filter barrel can fully contact the surface of the filter screen at the second discharge pipe. This allows the excess fertilizer powder adhering to the surface of the granules to be filtered off and discharged from the second discharge pipe. The granules then fall onto the conveyor mechanism inside the tower press and are transported out. After filtering for a period of time, the solenoid valve plate in the first discharge pipe can be opened periodically, so that the impeller rotates to a certain position and discharges the filtered compound fertilizer granules from the first discharge pipe. The granules then fall onto the conveyor mechanism inside the tower press and are transported to the next processing stage. This operation can filter off the excess fertilizer powder adhering to the surface of the compound fertilizer granules, making them easier to reuse later, avoiding waste of fertilizer powder, reducing enterprise costs, and improving the practicality of the tower press.

The filter screen 24 is located at the second discharge pipe 23. After the fertilizer granules are formed by the granulation disc 4, they are discharged from the outlet and fall into the filter barrel 21. Then, the motor 28 is started to drive the impeller 26 to rotate inside the filter barrel 21, so that the compound fertilizer granules falling into the filter barrel 21 can fully contact the surface of the filter screen 24 at the second discharge pipe 23. The excess fertilizer powder attached to the surface is filtered off and discharged from the second discharge pipe 23. It falls onto the conveying mechanism inside the tower production machine 1 and is transported out. After filtering for a period of time, the solenoid valve plate 25 in the first discharge pipe 22 can be opened periodically. After the impeller 26 rotates to a certain position, the filtered compound fertilizer granules are discharged from the first discharge pipe 22 and fall onto the conveying mechanism inside the tower production machine 1 to be transported to the next processing stage.

Magnet blocks 36 are fixedly connected to both sides of the filter screen 24. The mounting bracket 32 ​​is made of iron, and one side of the magnet block 36 is magnetically attracted to one side of the inner wall of the mounting hole 33. By setting the magnet block 36, after the filter screen 24 is inserted into the inner wall of the mounting hole 33, the magnet block 36 on one side will be attracted to the inner wall of the mounting hole 33, limiting the position of the filter screen 24 and preventing it from shaking.

[0035] Working Principle: The high-tower fertilizer production machine utilizes urea solution and its heat energy to mix powdered raw materials containing nitrogen, phosphorus, and potassium nutrients with urea in a specific ratio. The molten mixture is sprayed out from nozzles inside the tower and cooled by air as it falls into the granulation tray, where it is shaped into fertilizer granules. After the fertilizer granules are formed in the granulation tray 4, they are discharged from the outlet and fall into the filter barrel 21. Then, the motor 28 is started to drive the impeller 26 to rotate inside the filter barrel 21, so that the compound fertilizer granules falling into the filter barrel 21 can fully contact the surface of the filter screen 24 at the second discharge pipe 23, removing excess fertilizer adhering to the surface. The powder is filtered out and discharged from the second discharge pipe 23, falling onto the conveying mechanism inside the tower production machine 1 and being transported out. After filtering for a period of time, the solenoid valve plate 25 in the first discharge pipe 22 can be opened periodically, so that the impeller 26 rotates to a certain position and discharges the filtered compound fertilizer granules from the first discharge pipe 22, causing them to fall onto the conveying mechanism inside the tower production machine 1 and be transported to the next processing stage. This operation can filter out the excess fertilizer powder adhering to the surface of the compound fertilizer granules, making it convenient for continued use later, avoiding waste of fertilizer powder, reducing enterprise costs, and improving the practicality of the tower production machine 1.

[0036] When it is necessary to clean or replace the filter screen 24, the electric telescopic rod 34 can be activated to drive the mounting bracket 32 ​​to slide outward in the inner wall of the sliding hole 31, thereby sliding the filter screen 24 out of the filter barrel 21 for easy maintenance and cleaning of its surface, or removing it from the mounting hole 33 for easy replacement, improving the filtration effect of the filter device 2 and facilitating its maintenance.
