Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to a drying equipment for lubricating powder production. Background Art

[0002] Lubricating powder is applied in various fields and has a large production volume. In the production process of lubricating powder, a drying process is required. After retrieval, the prior art (application number: CN201821011353.1) records "a lubricating powder drying equipment, including a housing, a water storage cylinder, a powder cylinder, a motor, and a support column. The bottom end of the housing is welded to the support column. A water storage cylinder is arranged inside the housing, and water is injected into the water storage cylinder. A number of heating sheets are evenly arranged and installed inside the cylinder wall. The water storage cylinder is provided with a water inlet and a water outlet, which are correspondingly connected to the circular holes on the housing. Valves are installed on both the water outlet and the water inlet. A powder cylinder is installed inside the water storage cylinder. The powder cylinder is made of a heat-conducting material. A support frame is arranged between the powder cylinder and the water storage cylinder. A screw conveyor is connected inside the powder cylinder. The right end of the screw conveyor is connected to the rotating shaft of the motor through a coupling. A discharge port is arranged below the powder cylinder; this equipment adopts the contact drying method, which transfers heat to the object in contact with the partition wall by indirect heat conduction through the partition wall. The heat source is hot water. Water is ubiquitous, inexpensive, recyclable, energy-saving, and has high production efficiency, meeting the requirements of industrial production."

[0003] However, although the existing lubricating powder drying equipment achieves the drying effect of lubricating powder, there are still some deficiencies: the existing lubricating powder drying equipment realizes drying through hot water, but the hot water also needs to be heated by heating sheets and is energy-saving. Moreover, there is heat loss due to the indirect contact between hot water and lubricating powder; secondly, the screw conveyor is used for conveying and stirring, but the screw conveyor has a conveying effect when rotating and cannot ensure that the conveyed lubricating powder is completely dried. The drying time needs to be considered. If the screw conveyor is turned off, stirring cannot be carried out. If the discharge port is closed, it may cause the internal raw materials to accumulate at one end, resulting in the extrusion deformation of the screw conveyor. At the same time, with a single screw conveyor for stirring, the raw materials at the bottom may sink to the bottom, agglomerate during the drying process, and are not easily discharged, and the stirring effect is poor, resulting in low drying efficiency. Summary of the Utility Model

[0004] In order to overcome the defects of the prior art, a drying equipment for lubricating powder production is provided to solve the defects of large heat source loss and uneven stirring existing in the existing lubricating powder drying equipment, thereby solving the problems of poor drying effect and low efficiency.

[0005] To achieve the above object, a drying device for lubricating powder production is provided, including: a base, a drying cylinder, a power connection end, and a stirring assembly.

At the same time, the wire conduit is rotatably connected to the power supply rotary joint, and the power supply rotary joint is installed on the outer wall of the left side plate through a fixing bracket.

[0008] Further, two conductive rods are connected to the inner end of the wire conduit, and the conductive rods are connected to the electric heating rod through wires, and the conductive rods are embedded inside the heat conduction wall.

A second motor 41 is connected to the outer side of the main gear 42, and the second motor 41 is fixed to the outer wall of the left side plate 12.

[0022] In this embodiment, the base 1, the drying cylinder 2, the power connection end 3, and the stirring assembly 4 constitute the main structure of the drying device for lubricating powder production involved in this application, which is used for the drying process in the production of lubricating powder.

[0023] Specifically, the power supply rotary joint 32 adopts the existing technology to realize wiring at both ends and can be rotatably connected in the middle. Its principle is that there is a conductive slip ring inside the rotating structure.

[0024] Specifically, the electric heating rod 23 is set in an annular structure, and multiple groups are arranged at equal intervals in the length direction of the drying cylinder 2.

[0025] Specifically, the wiring terminal of the second motor 41 leads out the wiring through the wire conduit 34 inside the outer rotating sleeve 33 to realize the synchronous rotation of the second motor 41 and the drying cylinder 2.

[0026] As shown in Figure 1 、 Figure 2 and Figure 3 In [relevant figures], an outer rotating shaft 112 is connected to the right side of the drying cylinder 2, and the outer rotating shaft 112 rotates through the right side plate 11 and is connected to the first motor 111. An outer rotating sleeve 33 is connected to the left side of the drying cylinder 2, and the outer rotating sleeve 33 rotates through the left side plate 12 and is inserted and fixed with the wire conduit 34. At the same time, the wire conduit 34 is rotatably connected to the power supply rotary joint 32. The power supply rotary joint 32 is installed on the outer wall of the left side plate 12 through a fixing frame 31. Two conductive rods 35 are connected to the inner end of the wire conduit 34, and the conductive rods 35 are connected to the electric heating rod 23 through wires, and the conductive rods 35 are embedded inside the heat conduction wall 22.

[0027] Specifically, a fixed power cord is connected to the outer end of the power rotary joint 32, and the outer rotary end of the power rotary joint 32 is fixed to the left side plate 12 by a fixing frame 31, so that the inner rotary end can rotate freely after being connected to the wire conduit 34.

[0028] Specifically, there are two conductive rods 35 respectively connected to the live wire and the neutral wire, and the wires led out by the conductive rods 35 are electrically connected to all the electric heating rods 23.
