Description

Technical Field

[0001] The utility model belongs to the technical field of production devices of organic soil, and in particular relates to a reaction drying device for organic soil. Background Art

[0002] In the drilling industry, organic soil, as a basic component of oil-based drilling fluid, plays a vital role. It can not only significantly increase the viscosity and cutting force of the mud, effectively enhance the stability of the drilling fluid, but also significantly reduce the filtration loss of the oil-based drilling fluid, ensuring the safety and efficiency of the drilling operation. Therefore, the production quality and efficiency of organic soil are directly related to the performance of the drilling fluid and the cost and benefits of the entire drilling operation.

[0003] The traditional organic soil production process usually includes several key steps such as raw material preparation, kneading reaction and drying. Among them, the kneading reaction is the process of mixing and preliminary chemical reaction of various raw materials in a kneader, aiming to form a semi-finished organic soil with a certain viscosity and performance. However, in the existing production process, the kneading reaction and drying process are often carried out continuously in the same equipment (such as a kneader). Although this integrated production method simplifies the operation process, it also brings many problems and challenges.

[0004] First, the kneading reaction and drying process are carried out in the same equipment, which makes it impossible to continue to put in raw materials for new kneading reactions during the drying period, thus limiting the continuity and production efficiency of the production line. Secondly, due to the different requirements for temperature and humidity in the kneading reaction and drying process, integrated equipment often cannot meet the optimal conditions of both processes at the same time, resulting in unstable product quality or increased production costs. In addition, integrated equipment also has problems such as high maintenance costs and poor flexibility, making it difficult to meet the market's demand for diversified and personalized organic soil products.

[0005] To solve these problems, the industry has been exploring new organic soil production processes and equipment. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the above-mentioned defects of the prior art, provide a reaction drying device for organic soil, adopt a vibrating fluidized bed drying device to realize the separation of kneading reaction and drying process, improve production efficiency, reduce costs, improve product quality, and improve the overall level of organic soil production.

[0007] The organic soil reaction drying device described in the utility model comprises a kneader, a vibrating fluidized bed dryer and a pulverizer. The output end of the kneader is connected to the input end of the vibrating fluidized bed dryer, the output end of the vibrating fluidized bed dryer is connected to the input end of the pulverizer, the vibrating fluidized bed dryer is divided into three parts from top to bottom, namely, an upper box body, a material channel and a lower box body. An air inlet is arranged on the side wall of the lower box body, the air inlet is connected to the output end of the heater through a pipeline, and the input end of the heater is connected to the output end of the blower.

[0008] Preferably, an exhaust port is provided on the top of the upper box body, and the exhaust port is connected to the input end of the cyclone separator through a pipeline, and the output end of the cyclone separator is connected to the input end of the induced draft fan.

[0009] Preferably, a perforated plate is provided between the material passage and the lower box body for evenly distributing hot air and supporting the material.

[0010] Preferably, a vibration motor and a vibration isolation spring are provided on the body of the vibrating fluidized bed dryer to provide vibration and reduce noise transmission.

[0011] Preferably, one end of the material channel is provided with a material inlet for adding the organic soil to be dried; and the other end is provided with a dry product outlet for discharging the dried organic soil.

[0012] Preferably, the heater is an electric heating or steam heating device, which is used to heat the air delivered by the blower.

[0013] Preferably, the kneading machine is provided with a stirring device for mixing and pre-treating the organic soil.

[0015] Preferably, the pulverizer is a hammer mill or a ball mill, which is used to pulverize the dried organic soil into a desired particle size.

[0016] The organic soil reaction drying device described in the utility model, when working, the material organic soil is first added through the inlet of the kneader, and the internal stirring device starts to work to mix and pre-treat the organic soil to ensure the uniformity of the material. The organic soil pre-treated by the kneader is sent to the inlet of the material channel of the vibrating fluidized bed dryer through its output end. The blower sends air into the heater for heating to form hot air. The hot air enters the interior of the dryer through the air inlet of the lower box body, exchanges heat with the material, and achieves drying. The vibration motor is started, and while reducing noise through the vibration isolation spring, it provides vibration for the material, promotes the flow and mixing of the material in the material channel, and improves the drying efficiency. The exhaust gas generated during the drying process is discharged through the exhaust port of the upper box body and enters the cyclone separator, where the dust particles are separated and collected, and the clean gas is discharged by the induced draft fan. The dried organic soil is discharged from the dry product outlet of the material channel, enters the crusher, and is crushed to the required particle size to meet the needs of subsequent processing or use.

[0018] (1) The organic soil reaction drying device of the utility model realizes an integrated processing flow from pretreatment to finished product of organic soil through pretreatment by a kneading machine, high-efficiency drying by a vibrating fluidized bed dryer and particle size adjustment by a pulverizer. The combination of hot air circulation and vibration technology significantly improves the drying efficiency and ensures uniform heating of the material during the drying process, thus avoiding the problem of local overheating or insufficient drying.

[0019] (2) The organic soil reaction drying device of the utility model adopts a cyclone separator and induced draft fan combination, which effectively collects dust particles generated during the drying process and reduces environmental pollution. At the same time, the hot air circulation system fully utilizes thermal energy and reduces energy consumption, which is in line with the green and sustainable production concept.

[0034] The organic soil reaction drying device described in the utility model, when working, first, the organic soil to be treated is added through the entrance of the kneading machine 1.
