Description

Technical Field

[0001] The utility model relates to the technical field of chemical fertilizer production, and particularly relates to a feeding device for raw materials. Background Art

[0002] The phosphate fertilizer industry is an important part of the chemical fertilizer industry. Among them, the leading product of phosphate fertilizers is monoammonium phosphate, which is divided into powdered monoammonium phosphate and granular monoammonium phosphate according to its appearance. The powdered monoammonium phosphate devices in China basically adopt the "neutralization slurry concentration method for producing ammonium phosphate" production process, that is, dilute phosphoric acid reacts with ammonia to obtain a monoammonium phosphate slurry. After the slurry is concentrated to remove most of the water, it is pressurized by a pressurizing device and spray-dried to obtain a powdered monoammonium phosphate product.

[0003] When producing phosphate fertilizers through the above process, it is necessary to add powdered raw materials required for producing phosphate fertilizers. The traditional addition method is to manually adjust and add raw materials into the feeding hopper. However, this method has a high labor intensity and poor accuracy in controlling the amount of raw materials, resulting in difficulty in improving the production efficiency of phosphate fertilizers.

Detailed Embodiments

[0019] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0020] In the drawings, the same reference numerals all refer to the same components.

[0021] like Figures 1-3 As shown, the utility model provides a feeding device for raw materials, including a feeding hopper 1 and a feeding pipe 2, wherein the feeding hopper 1 is arranged at the top of the feeding pipe 2, and is characterized in that it also includes a feeding adjustment component 3, which is arranged on the outer wall of the feeding pipe 2 and extends into the feeding pipe 2 to control the feeding amount.

[0022] In this embodiment, the top opening of the feeding hopper 1 is connected to an external raw material elevator (not shown in the figure). The raw material elevator feeds the required raw materials into the feeding hopper 1 and into the feeding pipe 2. At the same time, the size of the opening in the feeding pipe 2 is controlled by adjusting the feeding adjustment component 3, thereby controlling the amount of raw material fed.

[0023] Furthermore, the feeding pipe 2 includes a first feeding pipe 21 and a second feeding pipe 22. The first feeding pipe 21 is vertically arranged, the feeding hopper 1 is connected to the top opening of the first feeding pipe 21, and the second feeding pipe 22 is inclined at the bottom opening of the first feeding pipe 21. A bracket 23 is provided at the bottom end of the second feeding pipe 22.

[0024] In this embodiment, the feeding pipe 2 is divided into two parts: a first feeding pipe 21 and a second feeding pipe 22. The first feeding pipe 21 is used to adjust the flow rate of raw materials through the feeding adjustment component 3, and the second feeding pipe 22 is used to connect to an external processing equipment.

[0025] Furthermore, the feeding adjustment assembly 3 includes a frame 31, a drive motor 32, a screw rod 33 and an L-shaped insertion adjustment plate 34. The frame 31 is arranged on the outer wall of the first feeding pipe 21, the screw rod 33 is horizontally arranged in the frame 31, and its two ends are respectively connected to the outer wall of the first feeding pipe 21 and the frame 31 through bearings. The insertion adjustment plate 34 is horizontally slidably connected to the outer wall of the first feeding pipe 21 close to the frame 31, and is threadedly connected to the screw rod 33. The drive motor 32 is arranged on the frame 31 and is connected to the screw rod 33.

[0026] In this embodiment, the insertion adjustment plate 34 is L-shaped. Its short plate part is threadedly connected to the lead screw 33. The long plate part horizontally inserts into the first feed pipe 21 from the slot on the outer wall of the first feed pipe 21 near one end of the frame 31. Both sides of the insertion adjustment plate 34 are in contact with the inner side walls on both sides of the first feed pipe 21. The drive motor 32 is a servo motor. By driving the lead screw 31 to rotate through the drive motor 32, the insertion adjustment plate 34 is driven to move horizontally, thereby changing the distance between the insertion adjustment plate 34 and the inner side wall of the first feed pipe 21 to control the amount of raw material passing through the first feed pipe 21.

[0027] Furthermore, the feeding adjustment assembly 3 further includes two optical axes 35. The two optical axes 35 are horizontally arranged in the frame 31, and both ends of the two are fixedly connected to the outer wall of the first feed pipe 21 near one side of the frame 31 and are respectively located on both sides of the lead screw 33. The insertion adjustment plate 34 is slidably connected to the optical axes 35.

[0028] In this embodiment, the short plates of the two optical axes 35 are slidably connected to the optical axes 35 to increase the stability when the insertion adjustment plate 34 moves.

[0029] Furthermore, it further includes a feeding assembly 4. The feeding assembly 4 is arranged on the outer wall of the feeding pipe 2 and is in communication with the inside of the feeding pipe 2.

[0030] Furthermore, the feeding assembly 4 includes an air supply pipe 41 and a blower 42. The air supply pipe 41 is arranged on the outer wall of the first feed pipe 21, and it is in communication with the inside of the first feed pipe 21 and is parallel to the direction of the second feed pipe 22. The blower 42 is arranged at the end of the air supply pipe 41 and is in communication with the inside of the air supply pipe 41.

[0031] In this embodiment, there is a bend at the connection between the first feed pipe 21 and the second feed pipe 22. The raw material may accumulate when passing through the bend. By the blower 42 cooperating with the air supply pipe 41 parallel to the second feed pipe 22 to blow air into the second feed pipe 22, the raw material can pass through the second feed pipe 22 faster to reduce the accumulation of the raw material at the bend.

[0032] The utility model is a feeding device for raw materials. Through the drive motor and the lead screw, the insertion adjustment plate can be driven to translate, thereby changing the opening width in the first feed pipe, and further changing the amount of raw material passing through the first feed pipe, so as to achieve a better raw material amount control effect. There is no need for manual control of the raw material amount, which reduces the labor intensity of workers.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
