Description

Technical Field

[0001] This utility model belongs to the technical field of drying equipment, and in particular relates to a drying equipment for ultra-strong steel chemical degreasing powder. Background Technology

[0002] In the field of steel surface treatment, the drying process of chemical degreasing powder is a crucial step in ensuring product quality. The moisture content of the degreasing powder directly affects the stability of its active ingredients and its degreasing effect, while uniform drying and thorough mixing are the core technical requirements for ensuring the quality of the degreasing powder.

[0003] Currently, traditional drying equipment generally suffers from low drying efficiency, insufficient mixing, and high material residue when processing chemical degreasing powder from steel, making it difficult to meet the demands for energy saving, high efficiency, and refined processing in large-scale production. Existing drying equipment mainly suffers from the following technical bottlenecks: First, the heating method is singular, often employing external hot air circulation or indirect heating via bottom heating plates. This results in uneven temperature distribution within the drying chamber, causing the degreasing powder to decompose due to localized overheating or clump due to excessive moisture content in low-temperature areas, affecting subsequent performance. Second, the mixing mechanism has a simple motion pattern; most equipment only uses a single rotating main shaft to drive the mixing blades, creating a planar vortex within the drying chamber, lacking a three-dimensional mixing effect. In particular, insufficient coverage of the material on the inner walls and bottom of the chamber prolongs drying time and easily leads to incomplete drying due to localized material retention.

[0004] With the increasing demands for surface treatment processes in the steel processing industry, the demand for high-activity, low-moisture-content ultra-strong steel chemical degreasing powder is growing rapidly. The technical deficiencies of traditional equipment have become a significant factor restricting industrial upgrading. Achieving uniform heating, three-dimensional mixing, and residue-free discharge of materials during the drying process has become a pressing technical challenge for the industry. To address this, we provide an ultra-strong steel chemical degreasing powder drying equipment to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a super-strong steel chemical degreasing powder drying equipment. Through the cooperation of the drying component and the mixing component, it solves the problem that the existing drying equipment cannot achieve uniform heating, three-dimensional stirring and residue-free discharge of materials.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a high-strength steel chemical degreasing powder drying device, comprising a drying component, a mixing component fixedly connected to the inner cavity of the drying component, a drying chamber, a feed pipe connected to one side of the top of the drying chamber, an exhaust pipe connected to the other side of the top of the drying chamber, mounting grooves arranged in a ring array on the inner wall of the drying chamber, a heating block fixedly connected to the inner wall of the mounting groove, a discharge port opened on one side of the bottom of the drying chamber, a plug threadedly connected to the inner cavity of the discharge port, and a driving motor fixedly connected to the top of the drying chamber via a mounting base. A drive shaft is fixedly connected to the bottom of the drive motor, a planetary gear agitator is fixedly connected to one end of the drive shaft located in the inner cavity of the drying chamber, and a reciprocating component is fixedly connected to one end of the drive shaft located at the top of the drying chamber.

[0008] The present invention is further configured such that a cap is threadedly connected to the top of the feed pipe, and a one-way exhaust valve is fixedly connected to the inner cavity of the exhaust pipe. The cap of the feed pipe and the one-way exhaust valve cooperate to achieve sealed feeding and safe exhaust, thereby preventing hot air leakage or the entry of external impurities during the drying process.

[0009] The present invention is further configured such that a support leg is fixedly connected to the bottom of the drying box, and a mounting base is fixedly connected to the bottom of the support leg. The support leg and the mounting base enhance the stability of the equipment, adapt to high-frequency vibration in the industrial drying environment, and ensure long-term operational reliability.

[0010] The present invention is further configured such that a circular hole is provided on the top of the drying box, and the first drive shaft is fixedly connected to the circular hole by a bearing. The bearing connects the first drive shaft to the drying box, reducing rotational resistance and improving sealing performance, thus preventing heat from escaping from the top gap.

[0011] The present invention is further configured such that the planetary gear agitator includes a bracket fixedly connected to the surface of a drive shaft and a drive gear ring fixedly connected to the top of the inner wall of the drying chamber. A secondary agitator rod is fixedly connected to the end of the bracket away from the drive shaft via a bearing. A driven gear is fixedly connected to the top of the secondary agitator rod. The driven gear meshes with the inner wall of the drive gear ring. The planetary gear transmission enables the secondary agitator rod to both revolve and rotate, thereby expanding the agitation coverage area and enhancing the lateral mixing effect of the material.

[0012] The present invention is further configured such that the reciprocating component includes a hexagonal hole at the bottom of a transmission shaft, a hexagonal prism slidably connected to the inner cavity of the hexagonal hole, a main stirring rod fixedly connected to the bottom of the hexagonal prism, a groove on the surface of the transmission shaft, a support plate fixedly connected to the top of the hexagonal prism, the other end of the support plate extending to the outside of the transmission shaft through the groove, a cam at the bottom of the support plate, a transmission shaft II fixedly connected to the bottom of the cam surface, one end of the transmission shaft II fixedly connected to the surface of the transmission shaft I through a bearing seat, and a driven bevel gear fixedly connected to the other end of the transmission shaft II. A driving bevel gear meshes with the bottom of the driven bevel gear, and the surface of the driving bevel gear is fixedly connected to the top of the drying chamber through the support plate. The cooperation between the hexagonal prism and the hexagonal hole restricts the rotational freedom of the main stirring rod, ensuring that it only performs up-and-down reciprocating motion. The cam and the driven bevel gear drive achieve stable driving of the lifting motion.

[0013] The present invention is further configured such that a scraper is fixedly connected to the bottom of the surface of the main stirring rod. The bottom of the scraper is chamfered, which reduces the discharge resistance, closely adheres to the bottom of the box to remove residue, and improves the cleanliness of the discharge.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model constructs a highly efficient and uniform drying system through the innovative design of a ring array heating block and a composite motion stirring mechanism. The heating blocks embedded in the inner wall of the drying chamber are distributed in a ring array, which can form a full-encirclement heating of the degreasing powder in the drying chamber. Compared with traditional bottom or single-sided heating, it significantly improves the uniformity of the temperature field in the chamber and avoids the problems of component decomposition or low-temperature agglomeration caused by local overheating. In the mixing component, the planetary gear stirring component drives the auxiliary stirring rod to revolve around the transmission shaft, while the driven gear and the drive gear ring mesh to achieve rotation, forming a three-dimensional stirring trajectory of "revolution + rotation". The upper and lower reciprocating component pushes the main stirring rod to make periodic up and down movements through the cam, so that the material undergoes both transverse shearing and mixing and longitudinal tumbling during the drying process, effectively breaking the dead corners of material accumulation and improving heat exchange efficiency.

[0016] 2. The chamfered scraper connected to the bottom of the main stirring rod of this utility model fits tightly against the bottom surface of the box. During the stirring process, it simultaneously removes residual materials adhering to the bottom of the box. With the up-and-down reciprocating motion, it can thoroughly turn over the materials near the bottom and inner wall of the box, solving the problem of incomplete drying caused by the blind spots of the stirring in traditional equipment. When discharging, the discharge port block is opened, and the scraper rotates with the main stirring rod to push the material to the discharge port, avoiding manual cleaning or contamination by residual materials. In addition, the auxiliary stirring rod and cam adopt a three-axis symmetrical layout to ensure uniform distribution of stirring force, reduce the agglomeration of materials caused by uneven force during the stirring process, and further improve the drying quality.

After drying, the outlet plug 15 is unscrewed, and the scraper 249 at the bottom of the main stirring rod 242 pushes the material to the outlet as it rotates, completing the discharge without residue.
