[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This solution is a post-processing stage in the phosphate fertilizer production process, used to convey granulated calcium phosphate particles for subsequent screening and packaging.

[0025] like Figs. 1-2 As shown, this utility model provides a technical solution: a conveying device for phosphate fertilizer production processes that prevents clogging and adhesion, including a first conveying component 1, and a second conveying component 2 disposed at the bottom of the output side of the first conveying component 1. It is understood that... Fig. 1 The diagram shows the conveyor, which consists of a motor, a rotating shaft, and a conveyor belt. This is existing technology and will not be described in detail in this solution.

[0026] A dry powder bin 3 and a rotary drum granulator 4 are distributed on the top of the first conveyor 1 and the second conveyor 2. The dry powder bin 3 contains mineral dry powder, calcium phosphate raw material, binder and other additives are mixed evenly in a certain proportion and then granulated by the rotary drum granulator 4.

[0027] To prevent the dry mineral powder from falling along the conveyor belt of the second conveyor 2 under its own gravity, in this scheme, the angle formed between the first conveyor 1 and the second conveyor 2 is 120-160 degrees, preferably 150 degrees.

[0028] In order to ensure that the dry mineral powder can be evenly spread on the conveyor belt of the second conveyor 2, in this solution, a uniform material bar 6 is provided on the top of the first conveyor 1. The uniform material bar 6 is located on the side of the dry powder bin 3 facing the rotary drum granulator 4 and is located directly above the conveyor belt of the first conveyor 1.

[0029] Specifically, the controller controls the opening of the material valve at the bottom of the dry powder bin 3, and the dry powder falls through the pipeline at the bottom of the dry powder bin 3 to the conveying belt of the first conveying member 1, and moves along with the conveying belt. After the dry powder on the conveying belt of the first conveying member 1 is flattened by the material uniformizing cross bar 6, the dry powder falls onto the conveying belt of the second conveying member 2 and moves upward along with the conveying belt. The controller controls the opening of the material valve on the rotary drum granulator 4, and the wet material particles discharged from the rotary drum granulator 4 fall onto the dry powder. In this way, since the wet material is isolated from the conveying belt of the second conveying member 2, the wet material particles discharged from the rotary drum granulator 4 can be effectively prevented from being adhered to the conveying belt of the second conveying member 2.

[0030] A spiral conveyor 5 for transporting calcium phosphate particles is arranged at the bottom of the output side of the second conveying member 2. As shown in Fig. 2 the spiral conveyor 5 includes a driving member and a conveying bin. The conveying bin includes a bottom plate 501, two side plates 502, two outer plates 504, a top plate, and a discharge pipe. The top plate has a feeding hopper 503 fixedly connected at the top thereof. The calcium phosphate particles conveyed by the conveying belt of the second conveying member 2 fall into the feeding hopper 503.

[0031] In the present scheme, the bottom of each of the two side plates 502 is formed with a first extension plate, and the two sides of the bottom plate 501 are formed with second extension plates. The first extension plate and the second extension plate on one side are detachably fixed. The detachable fixing mode can be bolt connection. A protrusion is formed at the bottom of the bottom plate 501, and an arc-shaped groove is formed at the top of the protrusion. Triangular blocks are formed on the side surfaces of the two side plates 502, so that a conveying channel is formed between the two triangular blocks and the arc-shaped groove.

[0032] The driving member includes a rotating shaft 505, the two sides of the shaft body of the rotating shaft 505 extend out of the outer plates 504. Helical blades are fixedly connected to the shaft body of the rotating shaft 505, and the helical blades are matched with the conveying channel. Support frames 506 are fixedly connected to the side surfaces of the outer plates 504. Support bearings 507 are fixedly connected to the top ends of the support frames 506. The inner ring of the support bearing 507 is fixedly connected to the shaft body of the rotating shaft 505. Compared with the support bearing 507 of the traditional spiral conveyor which is integrally connected to the outer plate 504, the connection mode of the present scheme is more convenient for the maintenance of the spiral conveyor. A support table is arranged outside the outer plate 504. A motor 508 is fixedly connected to the top end of the support table, and the output end of the motor 508 is fixedly connected to the end of the rotating shaft 505. When the controller controls the motor 508 to start, the motor 508 drives the rotating shaft 506 to rotate. Under the driving of the helical blades, the calcium phosphate particles move transversely along the conveying channel until they are discharged from the discharge pipe.

[0033] When the calcium phosphate particles adhered to the spiral blade need to be treated to prevent the calcium phosphate particles from blocking the conveying channel, the bottom plate 501 or the side plate 502 on one side is disassembled, and then the calcium phosphate particles adhered to the spiral blade are cleaned to prevent the spiral conveyor 5 from being blocked and to achieve the purpose of convenient cleaning.

[0034] Although the embodiments of the present application have been shown and described, it should be understood by those ordinary skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended embodiments and their equivalents.
