Description

Technical Field

[0001] This utility model relates to the field of humic acid production technology, specifically to a rapid feeding device for humic acid production. Background Technology

[0002] Humic acid is a widely distributed organic macromolecule in nature, with important applications in agriculture, industry, environmental protection, and many other fields. In agriculture, humic acid can improve soil structure, enhance soil fertility, and promote crop growth; in industry, it can be used in oil drilling, ceramics manufacturing, and other applications; and in environmental protection, it can treat pollutants such as wastewater and exhaust gases.

[0003] In the production of humic acid, the feeding process is crucial. However, existing feeding devices have several problems. First, the raw materials often contain large particles, which easily clog the screens during filtration, significantly reducing filtration efficiency and thus affecting overall feeding efficiency. Second, the raw materials may be damp. Damp raw materials not only have poor flowability but also tend to adhere to the inner walls of the equipment, further hindering normal material transport and also leading to low feeding efficiency. Furthermore, the existing feed temperature is relatively low, requiring extensive preheating of the reactor before the raw materials are delivered. The heat generated during reactor preheating is not fully utilized, resulting in energy waste and increased production costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a rapid feeding device for humic acid production. By installing a crushing wheel and a primary inclined vibrating large-pore screen in the pretreatment box, large particles in the raw materials can be crushed in a timely manner, preventing them from clogging the screen and ensuring that the material passes smoothly through the screen for filtration, thus greatly improving filtration efficiency and consequently increasing feeding efficiency. Simultaneously, a secondary inclined vibrating fine-pore screen and a crushing box are installed in the feeding treatment box to further refine and crush the material, ensuring that the particles entering the subsequent reaction vessel are uniform, thus guaranteeing the efficient production of humic acid.

[0005] This utility model is achieved using the following technical solution:

[0006] The rapid feeding device for humic acid production includes a feeding processing box and a storage box. A pretreatment box is located below the storage box. The pretreatment box contains a crushing wheel and a primary inclined vibrating large-hole screen. The pretreatment box is connected to the feeding processing box through a spiral feeding pipe. The feeding processing box contains a secondary inclined vibrating fine-hole screen.

[0007] The secondary inclined vibrating fine-pore screen performs fine screening of the pretreated raw materials, ensuring uniform particle size of the material entering the reactor. The crushing box can further crush large particles of raw materials that are not completely crushed, preventing large impurities from entering the reactor and affecting product quality. The storage tank is used to store raw materials for humic acid production, providing a stable supply of raw materials for subsequent feeding and processing.

[0008] The crushing wheel is located above the primary inclined vibrating large-aperture screen, and the pretreatment box is equipped with a heating and drying coil. The crushing wheel crushes large-particle raw materials, and the primary inclined vibrating large-aperture screen, in conjunction with a vibrator, performs preliminary screening to remove large-particle impurities. The heating and drying coil dries the damp raw materials, improving material flowability and increasing feeding efficiency.

[0009] A vibrator is installed on the outer wall of the pretreatment box, and the connection between the spiral feeding pipe and the pretreatment box is located below the first-stage inclined vibrating large-hole screen.

[0010] A cyclone separator is installed above the feed processing box. The cyclone separator is connected to the bag filter dust collector through the separator. A fan is installed between the separator and the bag filter dust collector.

[0011] The pretreatment box is connected to a cyclone separator via a pipe, and the separator has a separation plate inside.

[0012] A crushing box is located on the outside of the feed processing box, and a crushing device is installed inside the crushing box. The upper part of the crushing box is connected to the feed processing box, with the connection point located above the secondary inclined vibrating fine-pore screen. The lower part of the crushing box is also connected to the feed processing box, with the connection point located below the secondary inclined vibrating fine-pore screen. The crushing box further crushes large particles of raw material that are not completely crushed in the feed processing box, ensuring that the raw material particles entering the reactor meet production requirements and guarantee product quality.

[0013] The feed processing box is connected to the reactor via an elevator. A reactor temperature control sleeve is provided on the outside of the reactor. A steam inlet pipe is connected to the reactor temperature control sleeve. The reactor temperature control sleeve is connected to the heating and drying coil via a connecting pipe.

[0014] The working principle of this utility model is as follows:

[0015] The raw materials for humic acid production are stored in a storage bin. Under gravity, the raw materials enter a pretreatment bin below. In the pretreatment bin, a crushing wheel at a certain speed (100-150 revolutions per minute) crushes large particles in the raw materials. Simultaneously, a vibrator is activated, causing the primary inclined vibrating screen to vibrate (vibration frequency controlled at 50-80Hz), performing preliminary screening of the crushed raw materials. Larger impurities are removed, and qualified raw materials pass through the primary inclined vibrating screen. During this process, a heating and drying coil heats and dries the raw materials, controlling the moisture content to 10%-15% (heating temperature at 50-70℃).

[0016] The pre-treated raw materials are conveyed to the feed tank via a spiral feed pipe. Inside the feed tank, a two-stage inclined vibrating fine-pore screen further screens the raw materials (vibration frequency 60-90Hz) to remove fine impurities, ensuring more uniform particle size in the subsequent reaction vessel. If larger particles remain incompletely crushed, they can be further crushed by the crushing device in the crushing chamber. The crushed material returns to the feed tank and, after passing the two-stage inclined vibrating fine-pore screen screening, proceeds to the next step.

[0017] Qualified raw materials in the feed tank are conveyed to the reactor via an elevator. Steam is introduced into the reactor's temperature control jacket via a steam inlet pipe for preheating (steam temperature controlled at 120-150℃). The heat generated during preheating is then transferred to the heating and drying coil via connecting pipes to dry the raw materials. After entering the reactor, the raw materials undergo reaction under suitable temperature (80-120℃) and pressure (0.5-1.0MPa) conditions.

[0018] Above the feed processing box, a cyclone separator initially separates the dust generated during the feeding process. The separated gas enters the separator, where the separation plates further separate impurities from the gas. Finally, the purified gas is transported by a fan to a bag filter for further treatment, ensuring that the emitted gas meets environmental protection standards.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] (1) This device can promptly crush large particles in the raw materials by setting crushing wheels and a primary inclined vibrating large-hole screen in the pretreatment box, avoiding large particles from clogging the screen and ensuring that the material passes smoothly through the screen for filtration, which greatly improves the filtration efficiency and thus improves the feeding efficiency. At the same time, a secondary inclined vibrating fine-hole screen and a crushing box are set in the feeding treatment box to further finely screen and crush the material, ensuring that the material particles entering the subsequent reaction vessel are uniform, thus providing a guarantee for the efficient production of humic acid.

[0021] (2) The heating and drying coil inside the pretreatment box can heat and dry the damp raw materials, effectively improve the flowability of the raw materials, reduce the adhesion of the raw materials to the inner wall of the equipment, make the materials smoother during the conveying process, and further improve the feeding efficiency.

[0022] (3) The temperature control jacket of the reactor is connected to the heating and drying coil through a connecting pipe, so that the heat generated by the preheating of the reactor can be transferred to the heating and drying coil for drying raw materials, thus realizing the full utilization of energy and reducing production costs.

The crushing wheel 11 is located above the primary inclined vibrating large-aperture screen 12. The pretreatment box 3 contains a heating and drying coil 14. The crushing wheel 11 crushes large particles of raw material, and the primary inclined vibrating large-aperture screen 12, in conjunction with a vibrator 13, performs preliminary screening to remove large impurities. The heating and drying coil 14 dries the moist raw material, improving material flowability and increasing feeding efficiency. The spiral feeding pipe 4 can stably and efficiently transport the pretreated raw material to the feed processing box 1, avoiding blockages during transport. A vibrator 13 is installed on the outer wall of the pretreatment box 3. The connection between the spiral feeding pipe 4 and the pretreatment box 3 is located below the primary inclined vibrating large-pore screen 12. A cyclone separator 7 is installed above the feed treatment box 1. The cyclone separator 7 is connected to the bag filter 10 through a separator 8. A fan 9 is installed between the separator 8 and the bag filter 10. The pretreatment box 3 is connected to the cyclone separator 7 through a pipe. The separator 8 has a separation plate 17 inside. A crushing box 16 is installed on the outer side of the feed treatment box 1. The crushing box 16 has a crushing device inside. The crushing box 16 is connected to the feed treatment box 1 at the top, with the connection point located above the secondary inclined vibrating fine-pore screen 15. The crushing box 16 is also connected to the feed treatment box 1 at the bottom, with the connection point located below the secondary inclined vibrating fine-pore screen 15.

[0028] The rapid feeding device in the above-mentioned humic acid production process includes the following steps during operation:

[0029] (1) The raw materials for humic acid production are stored in the storage box 2. Under the action of gravity, the raw materials enter the pretreatment box 3 below. In the pretreatment box 3, the crushing wheel 11 crushes the large particles in the raw materials at a certain speed. At the same time, the vibrator 13 is started, causing the first-stage inclined vibrating large-pore screen 12 to vibrate, and the crushed raw materials are initially screened. Larger particles of impurities are screened out, and qualified raw materials pass through the first-stage inclined vibrating large-pore screen 12. During this process, the heating and drying coil 14 heats and dries the raw materials. (2) The pretreated raw materials are transported to the feed processing box 1 through the spiral feeding pipe 4.

If there are still large particles in the raw materials that have not been completely crushed, they can be crushed again by the crushing device in the crushing box 16. The crushed material returns to the feed processing box 1 and enters the next step after being screened by the second-stage inclined vibrating fine-pore screen 15. (3) The qualified raw materials in the feed processing box 1 are transported to the reactor 6 by the elevator 5.

(4) Above the feed processing box 1, the cyclone separator 7 performs preliminary separation of the dust generated during the feeding process. The separated gas enters the separator 8. The separation plate 17 inside the separator 8 further separates the impurities in the gas. Finally, the purified gas is transported to the bag filter dust collector 10 for deep treatment by the fan 9.
