Description

Technical Field

[0001] The utility model belongs to the field of compound fertilizer granulation equipment, and particularly relates to a disk material collector for a granulation tower. Background Technique

[0002] In the high tower granulation process, fertilizers are melted into a liquid state at the top of the high tower and then sprayed downward from the top. During the falling process, the materials solidify to form spheres and naturally scatter onto the receiving disk at the bottom of the tower, and then are collected centrally.

[0003] Generally, a spiral conveyor scraper is used to convey the compound fertilizer particles to the central discharge port on the receiving disk. Since the spiral conveyor scraper has a certain weight, when the conveyor walking mechanism drives the spiral conveyor scraper to rotate around the center of the fixed disk, it needs to overcome a large frictional force, resulting in relatively high energy consumption. Moreover, the compound fertilizer particles have strong adhesiveness, and the spiral conveyor is prone to blockage during the conveying process, and it is necessary to stop the machine for cleaning.

[0004] Therefore, we propose a disk material collector for a granulation tower to solve the above problems. Content of the Utility Model

[0005] Aiming at the problem that generally a spiral conveyor scraper is used to convey the compound fertilizer particles to the central discharge port on the receiving disk. Since the spiral conveyor scraper has a certain weight, when the conveyor walking mechanism drives the spiral conveyor scraper to rotate around the center of the fixed disk, it needs to overcome a large frictional force, resulting in relatively high energy consumption. Moreover, the compound fertilizer particles have strong adhesiveness, and the spiral conveyor is prone to blockage during the conveying process, the utility model provides a disk material collector for a granulation tower.

[0006] The solution adopted by the utility model to solve its technical problems is: a disk material collector for a granulation tower, including a tower wall material receiving device, a second belt conveyor, a scraping mechanism, a discharge hopper, and a receiving disk arranged at the inner bottom of the granulation tower;

[0007] A plurality of legs are installed at the bottom of the receiving disk. The tower wall material receiving device is installed on the inner wall of the granulation tower and is located above the receiving disk. The second belt conveyor is arranged below the receiving disk, and one end of it extends to the outside of the granulation tower.

[0008] A notch is transversely opened in the middle section of the receiving disk. Two mounting plates are installed at the bottom of the notch. Two first belt conveyors are installed between the two mounting plates. The two first belt conveyors are arranged one on the left and one on the right, and there is a gap between the two first belt conveyors to form a blanking channel.

[0009] The discharge hopper is installed at the bottom of the receiving disk. The feed port of the discharge hopper corresponds to the blanking channel, and its discharge port corresponds to the second belt conveyor.

[0010] The scraper mechanism includes a rotating shaft, a driving assembly and a scraper. The rotating shaft is arranged in the discharge hopper, and its upper end passes through the discharge channel and is equipped with a rotating arm. The scraper is installed on the rotating arm and contacts the upper surface of the receiving disc.

[0011] The driving assembly is installed in the discharge hopper and can drive the rotating shaft to rotate.

[0012] Preferably, a universal ball wheel is installed at one end of the rotating arm away from the rotating shaft.

Specific embodiments

[0023] The present invention will be further described below in conjunction with the drawings and embodiments.

[0024] Please refer to Figures 1-4 , the present invention provides a technical solution for a disc material collector for a granulation tower:

[0025] Embodiment 1:

[0026] According to Figures 1-4 shown, it includes a tower wall material collection device 2, a second belt conveyor 5, a scraping mechanism, a discharge hopper 6, and a material collection disc 31 arranged at the inner bottom of the granulation tower 1.

[0027] A plurality of support legs 34 are installed at the bottom of the material collection disc 31 to support the material collection disc 31. The tower wall material collection device 2 is installed on the inner wall of the granulation tower 1 and is located above the material collection disc 31, so that the compound fertilizer particles are concentrated and scattered on the material collection disc 31.

[0028] The second belt conveyor 5 is arranged below the material collection disc 31, and one end of it extends to the outside of the granulation tower 1 to convey the compound fertilizer particles outside the granulation tower 1.

[0029] A notch is transversely opened in the middle section of the material collection disc 31. Two mounting plates 32 are installed at the bottom of the notch. Two first belt conveyors 33 are installed between the two mounting plates 32. The two first belt conveyors 33 are arranged one on the left and one on the right, and there is a gap between the two first belt conveyors 33 to form a feeding channel. The two first belt conveyors 33 convey the compound fertilizer particles in the direction of the feeding channel.

[0030] The discharge hopper 6 is installed at the bottom of the material collection disc 31. The feeding port of the discharge hopper 6 corresponds to the feeding channel, and its discharge port corresponds to the second belt conveyor 5, so that the compound fertilizer particles fall into the discharge hopper 6 and fall onto the second belt conveyor 5 through the discharge hopper 6.

[0031] The scraping mechanism includes a rotating shaft 75, a driving assembly, and a scraper 77. The rotating shaft 75 is arranged in the discharge hopper 6, its upper end passes through the feeding channel and is installed with a rotating arm 76. The scraper 77 is installed on the rotating arm 76 and contacts the upper surface of the material collection disc 31.

[0032] It also includes an arc-shaped diverter plate 71, the left end of which is fixedly connected to the left side of the inner wall of the discharge hopper 6. By setting the arc-shaped diverter plate 71, the compound fertilizer particles can be diverted to prevent the compound fertilizer particles from contacting the reduction motor 73. A bearing is installed on the top of the arc-shaped diverter plate 71, and the bearing is mounted on the bottom end of the rotating shaft 75.

[0033] The driving assembly includes a reduction motor 73 and two sprockets 74. The reduction motor 73 is installed on the left side of the inner wall of the discharge hopper 6 and is located below the arc-shaped diverter plate 71. The two sprockets 74 are respectively mounted on the bottom end of the rotating shaft 75 and the output shaft of the reduction motor 73. The two sprockets 74 are connected by a chain 72. By starting the reduction motor 73, the rotating shaft 75 is driven to rotate under the transmission action of the chain 72 and the two sprockets 74. The rotating shaft 75 drives the rotating arm 76 and the scraper 77 to rotate. During the rotation process, the scraper 77 collects the compound fertilizer particles on the receiving disc 31 and scrapes the compound fertilizer particles onto two belt conveyors 33.

[0034] When used specifically, the utility model uses a disc collecting machine for a granulation tower 1. The fertilizer melts into liquid at the top of the granulation tower 1 and is then sprayed downward from the top. During the falling process, the material solidifies and forms a ball, which is scattered onto the collecting disc 31.

[0035] Start the reduction motor 73, and drive the rotating shaft 75 to rotate under the transmission action of the chain 72 and the two sprocket wheels 74. The rotating shaft 75 drives the rotating arm 76 and the scraper 77 to rotate. The scraper 77 collects the compound fertilizer particles on the receiving disc 31 during the rotation process, and scrapes the compound fertilizer particles onto the two belt conveyors 1 33. The two belt conveyors 1 33 convey the compound fertilizer particles, so that the compound fertilizer particles fall into the discharge hopper 6, and fall onto the belt conveyor 2 5 through the discharge hopper 6. Finally, the belt conveyor 2 5 transports the compound fertilizer particles to the outside of the granulation tower 1.

[0036] Embodiment 2:

[0037] On the basis of the first embodiment, Figure 2 As shown, a universal ball wheel 4 is installed at one end of the rotating arm 76 away from the rotating shaft 75, and the universal ball wheel 4 is used to provide auxiliary support to the rotating arm 76 to improve the stability of the rotating arm 76 during the rotating process.
