Description

Technical Field

[0001] The utility model relates to the technical field of humic acid fertilizers, in particular to a granulation and coating device for humic acid in landfill leachate. Background Art

[0002] Humic acid is a macromolecular organic substance widely existing in nature. It is widely used in agriculture, forestry, animal husbandry, petroleum, chemical industry, building materials, medicine and health, environmental protection and other fields. Especially now that ecological agriculture construction, pollution-free agricultural production, green food, pollution-free environmental protection, etc. are advocated, humic acid is highly praised.

[0003] Humic acid contains some elements required for plant growth and development, which can improve soil and increase fertility. In the field of agriculture and forestry, it is mainly used for the preparation of fertilizers. In the process of fertilizer preparation, humic acid is mixed evenly with other ingredients, such as urea, ammonium bicarbonate, sodium nitrate, etc., and then granulated by granulating equipment for use. However, it is found during use that the fertility of humic acid fertilizer is not released evenly. Therefore, there is a method of coating humic acid fertilizer particles so that the fertilizer effect can be evenly maintained. However, there is a lack of relevant granulation and coating equipment.

[0004] In addition, traditional humic acid comes from animal and plant remains, mainly plant remains, which are a type of organic matter formed and accumulated through the decomposition and transformation of microorganisms and a series of geochemical processes. People have found through research that leachate also contains humic acid. Therefore, on the basis of realizing the utilization of waste resources, a device that can simultaneously granulate and encapsulate humic acid to effectively improve the fertilizer efficiency is a problem that needs to be solved. Utility Model Content

[0005] The purpose of the utility model is to provide a granulation and coating device for humic acid in landfill leachate in view of the deficiencies of the above-mentioned prior art, so as to achieve the purpose of granulating and coating humic acid at the same time, and at the same time control the granulation particle size and the uniformity of the coating, so as to effectively improve the fertilizer efficiency.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a granulation and coating device for humic acid in landfill leachate, comprising a rotating frame, on which a driving motor is installed, the driving motor is connected to a disc body, an inner disc body and an outer disc body are arranged in the disc body, a scraper is arranged in the inner disc body, and a spray device is arranged in the outer disc body.

[0007] Furthermore, it also includes a support frame, which is rotatably connected to the rotating frame.

[0008] Furthermore, the support frame is hinged to one end of the hydraulic device, and the other end of the hydraulic device is hinged to the rotating frame.

[0009] Furthermore, a bracket is installed on the rotating frame, and the spray device and the scraper are respectively installed on the bracket.

[0010] Furthermore, the scraper is arranged perpendicular to the inner disc, the lower side of the scraper matches with the bottom of the inner disc, and the left and right sides of the scraper match with the side walls of the inner disc.

[0011] Furthermore, the other left and right sides of the scraper extend to the center of the inner disk.

[0012] Beneficial effects of the utility model:

[0013] 1. By adjusting the angle of the disc and the rotation speed, the particle size of the humic acid particles can be adjusted, so that humic acid particles of different specifications can be obtained;

[0014] 2. The scraper can scrape the bonded materials to ensure the stability of the device operation;

[0015] 3. The spraying device can achieve uniform coating of humic acid particles, thus playing a positive role in maintaining the uniform fertilizer effect;

[0016] 4. The coating slows down the release rate of fertilizer nutrients, and can also absorb water, resist drought and retain water, improve soil structure, and at the same time realize the recycling of humic acid in the leachate;

[0017] 5. Using humic acid separated from landfill leachate as raw material can achieve effective utilization of resources, reduce costs, promote environmental protection, improve the growth of seedlings, and reduce the damage to the soil caused by excessive use of fertilizers.

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0024] Embodiments of the present utility model:

[0025] like Figure 1-3 As shown, in this embodiment, a support frame 1 is provided, a rotating frame 2 is rotatably connected to the support frame 1, a hydraulic device 3 is hinged between the support frame 1 and the rotating frame 2, and a driving motor 21 is installed at the front end of the rotating frame 2, and the driving motor 21 is connected to the disc body 4.

[0026] The disc body 4 includes an inner disc body 41 and an outer disc body 42 . A scraper 6 is arranged in the inner disc body 41 , and a spray device 5 is installed in the outer disc body 42 . The scraper 6 and the spray device 5 are connected to a bracket 7 , and the bracket 7 is connected to the rotating frame 2 .

[0027] The principle of this utility model is:

[0028] When the utility model is in use, the angle of the rotating frame 2 is adjusted by the hydraulic device 3. After the angle of the rotating frame 2 is adjusted, the humic acid material is mixed with other components (such as urea, ammonium bicarbonate, sodium nitrate, etc.) and poured into the inner disk body 41 of the disc body 4. At this time, the driving motor 21 is started to drive the disc body 4 to rotate.

[0029] By adjusting the angle of the rotating frame 2 and the speed of the motor, the particle size of the humic acid particles can be controlled. The scraper 6 is set to prevent the humic acid from sticking and agglomerating on the inner wall of the inner disk 41; the humic acid particles after granulation overflow from the upper opening of the inner disk 41, and the overflowed humic acid particles are coated in the outer disk 42.

[0030] The coating is carried out by spraying with a spray device 5. During the process, the spray device 5 is connected to the coating material liquid (such as gelatin, sodium cellulose, zeolite powder and soybean oil, etc.) through a pump. It is not difficult for those skilled in the art to understand and will not be described in detail. The coating material is existing and fertilizers with different properties can be prepared according to different coating materials. It will not be described in detail. At the same time, by spraying, the humic acid particles can be evenly coated, which plays a positive role in maintaining the uniform fertilizer effect.
