Description

TECHNICAL FIELD

[0001] The utility model relates to humic acid production technical field, concretely is belt feeding and impurity removal device. BACKGROUND

[0002] Humic acid is an important organic substance widely used in agriculture, industry, environmental protection and other fields. In agriculture, humic acid can be used as a fertilizer synergist to improve soil structure, increase fertilizer utilization rate and promote crop growth; in industry, it can be used in the processing of petroleum, coal and other industries; in the field of environmental protection, it can be used for wastewater treatment, heavy metal adsorption, etc.

[0003] In the production process of humic acid, the feeding link is crucial. The existing feeding device has many drawbacks, which seriously affects the production quality and efficiency of humic acid. From the perspective of impurity filtration, the traditional feeding device mostly uses the mode of directly feeding the material into the production tank through the conveyor belt after one-time filtration. This mode cannot effectively remove large-particle impurities and iron-containing impurities in the material, resulting in low purity of the produced humic acid product, affecting its application effect in various fields. Moreover, the one-time filtration efficiency is low, causing a large amount of large-particle material to accumulate on the vibrating screen, which not only hinders the smooth progress of the subsequent production process, but also increases the frequency and cost of equipment cleaning. In terms of waste material recycling, the existing device lacks an effective waste material recycling mechanism when feeding on the conveyor belt, and material particles frequently fall off. If these fallen material particles are not recycled in time, not only will it cause serious waste of raw materials and increase production costs, but also may scatter in the production environment, causing pollution and affecting the health of the operating personnel. From the perspective of temperature control, material at room temperature directly enters the production tank, which will have an adverse effect on the production process when the room temperature is low. Because some chemical reactions in the production process of humic acid have specific requirements for temperature, material at room temperature will prolong the reaction time, reduce the production efficiency, and even may affect the quality stability of the product. SUMMARY

[0004] In view of the shortcomings in the prior art, the utility model aims to provide a belt feeding and impurity removal device, which can significantly improve the impurity removal effect through a multi-stage filtration system of an inclined rolling screen and a vibrating screen. The rolling screen mesh inside the inclined rolling screen cooperates with the inclination angle design to efficiently screen out large-particle impurities by utilizing gravity and rotation principle, and the magnet configured below can accurately adsorb iron-containing impurities, thereby improving the purity of the material from the source. The subsequent vibrating screen further finely screens the material to effectively remove small-particle impurities, ensuring that the material entering the production tank has a significantly reduced impurity content, thereby improving the quality of the humic acid product and enabling it to better perform in various application fields.

[0005] The utility model is implemented by adopting the following technical solutions:

[0006] The belt feeding and impurity removing device comprises a raw material storage tank, the raw material storage tank is connected with a vibrating screen through an inclined rolling screen, the vibrating screen is connected with a production tank through a belt feeder, the belt feeder is internally provided with a belt, the belt feeder is connected with the raw material storage tank through a recovery tank below the belt feeder, a scraper is arranged below the belt, and the belt is tangent to the scraper.

[0007] The belt is arranged in an inclined upward manner, and a transmission system of a driving wheel and a driven wheel can stably and efficiently convey the materials to the production tank. The reasonable layout of the air inlet and the air outlet not only realizes the preheating function of the materials, but also effectively adjusts the air circulation in the belt feeder, prevents the accumulation of moisture and hot air, and creates good environmental conditions for the conveying of the materials.

[0008] The inclined rolling screen is internally provided with a rolling screen mesh, the rolling screen mesh is provided with a magnet below, a secondary guide plate is connected between the inclined rolling screen and the vibrating screen, and the vibrating screen is internally provided with a vibrating screen mesh.

[0009] The raw materials flow into the inclined rolling screen from the raw material storage tank. The inclined rolling screen runs at a specific inclination angle (generally 15°-30°) and speed (5-10 revolutions per minute), the rolling screen mesh in the inclined rolling screen preliminarily screens the raw materials to remove large-particle impurities, and the magnet below the rolling screen mesh fully plays a role in adsorbing iron-containing impurities in the raw materials.

[0010] The belt is arranged in an inclined upward manner, the belt is internally provided with a driving wheel and a driven wheel, and the driving wheel is located on the side close to the production tank.

[0011] The belt feeder is provided with a vibrator and an air inlet, the air inlet is located on the side close to the production tank, the recovery tank is located on the side close to the vibrating screen, and the vibrator is located between the air inlet and the recovery tank.

[0012] The belt feeder is internally provided with an upper baffle, the upper baffle is located on the side close to the driving wheel, and the belt feeder is provided with an air outlet.

[0013] A primary guide plate is arranged between the belt feeder and the production tank, and a stirring paddle is arranged in the production tank.

[0014] A heating jacket is arranged on the outside of the production tank, the heating jacket is connected with a heat recovery tank through a pipeline, the heat recovery tank is internally provided with a heat recovery tank coil pipe, and the heat recovery tank coil pipe is connected with the air inlet through a pipeline.

[0015] An indirect discharger is arranged between the belt feeder and the recovery tank, and a recovery pipeline is arranged between the recovery tank and the raw material storage tank.

[0016] The working principle of the device is as follows:

[0017] Raw material pretreatment: the raw material flows from the raw material storage tank into the inclined rolling screen. The inclined rolling screen operates at a specific inclination angle (generally 15°-30°) and rotation speed (5-10 revolutions per minute), and the rolling screen inside the screen performs preliminary screening on the raw material to remove larger impurity particles. At the same time, the magnet below the rolling screen fully plays its role to adsorb the iron-containing impurities in the raw material. During this process, the rotation speed and inclination angle of the rolling screen can be adjusted appropriately according to the characteristics and impurity content of the raw material to achieve the best screening and impurity removal effect.

[0018] Further screening: the raw material preliminarily treated by the inclined rolling screen is smoothly fed into the vibrating screen through the secondary guide plate. The vibrating screen inside the vibrating screen vibrates at a set frequency (100-200 times per minute) and amplitude (5-10 mm) to further screen out smaller impurity particles. By finely adjusting the frequency and amplitude of the vibrating screen, different properties of the raw material can be adapted to ensure the optimization of the screening effect and provide high-quality materials for subsequent production processes.

[0019] Feeding and conveying: the raw material treated by the vibrating screen is conveyed to the production tank by the belt feeder. The belt is arranged in an inclined upward direction (inclination angle of 10°-20°) and is driven to rotate at a certain speed (1-2 meters per minute) by the driving wheel. The air inlet blows preheated air (controlled at 30-50℃) to preheat the material on the belt. During the entire feeding and conveying process, the belt speed, vibrator frequency and hot air temperature of the air inlet are accurately controlled to ensure that the material can be stably and efficiently conveyed to the production tank.

[0020] Material recycling: during belt feeding, the scraper will scrape the surface, and the scraped raw material will fall into the recycling box by gravity. The particles in the recycling box are sent back to the raw material storage tank through the recycling pipeline, realizing the recycling of raw materials.

[0021] Production tank treatment: the material conveyed by the belt feeder is smoothly fed into the production tank through the primary guide plate. The stirring paddle in the production tank stirs the material at a rotation speed of 30-60 revolutions per minute to ensure uniform mixing of the material. At the same time, the heating jacket accurately heats the production tank according to the specific requirements of the production process (temperature at 60-80℃), providing suitable temperature conditions for the production of humic acid, thereby ensuring product quality and production efficiency.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] (1) Through the multi-stage filtering system of the inclined rolling screen and the vibrating screen, the impurity removal effect can be significantly improved. The rolling screen inside the inclined rolling screen cooperates with the inclined angle design, which can efficiently screen out larger particle impurities by using the principles of gravity and rotation, and the magnet configured below can accurately adsorb iron-containing impurities, thereby improving the purity of the material from the source. The subsequent vibrating screen further finely screens the material, effectively removing smaller particle impurities, ensuring that the material entering the production tank has a significantly reduced impurity content, thereby improving the quality of humic acid products and enabling them to better perform in various application fields.

[0024] (2) A recovery tank is arranged below the belt feeder, and is connected to the raw material storage tank through a recovery pipeline. Meanwhile, the belt and the scraper are tangent, which can timely and effectively scrape off the raw materials that are not easy to remove on the belt. The arrangement of the vibrator further prevents waste from accumulating in the belt feeder, ensuring that the falling material particles can smoothly enter the recovery tank. The hot air at the air inlet not only helps to preheat the material, but also prevents waste from sticking to a certain extent, facilitating waste recovery. This waste recovery mechanism not only avoids waste of raw materials, reduces production costs, but also reduces pollution of the production environment, meets the requirements of environmentally friendly production, and creates a cleaner and safer production workshop environment.

[0025] (3) The heating jacket arranged outside the production tank can accurately heat the material in the tank according to production needs, ensuring that the production process is carried out at an appropriate temperature. Meanwhile, the design of the heat recovery tank and the heat recovery tank coil realizes effective recovery and reuse of the heat emitted by the heating jacket. The recovered heat preheats the material on the belt through the air inlet, so that the material is closer to the ideal reaction temperature when entering the production tank. This design greatly improves production efficiency, shortens production cycle, reduces energy consumption and production cost, and ensures the stability of product quality when the room temperature is low.
