Description

Technical Field

[0001] The invention relates to the technical field of drying equipment, and in particular to a drying device capable of being heated evenly. Background Art

[0002] Lubricating powder is used in various fields and its production volume is large. In the production process of lubricating powder, a drying process is required. Traditional drying is carried out by heating and sunlight irradiation, but these methods have low production efficiency, hinder the improvement of productivity, and are not conducive to large-scale production.

[0003] After searching, the prior art (publication number: CN208567462U) records "a kind of lubricating powder drying equipment, including a shell, a water storage cylinder, a powder cylinder, a motor, and a support column. The bottom end of the shell is welded with the support column. A water storage cylinder is arranged inside the shell, and water is injected into the water storage cylinder. Several heating plates are evenly arranged and installed inside the cylinder wall. The water storage cylinder is provided with a water inlet and a water outlet, and is connected to the circular hole on the shell. Valves are installed on the water outlet and the water inlet. A powder cylinder is installed in the water storage cylinder. The powder cylinder is made of heat-conducting material. A support frame is provided between the powder cylinder and the water storage cylinder. A auger is connected inside the powder cylinder. The right end of the auger is connected to the rotating shaft of the motor through a coupling. A discharge port is provided below the powder cylinder. This equipment adopts a contact drying method, which indirectly transfers heat to the object in contact with the partition wall by heat conduction through the partition wall. The heat source is hot water, which is ubiquitous, low-priced, recyclable, energy-saving, and has high production efficiency, meeting the requirements of industrial production."

[0004] Although the lubricating powder drying equipment in the prior art has achieved a high drying efficiency, it still has some shortcomings: the powder cylinder involved in the existing lubricating powder drying equipment is only transported by an auger, resulting in a deviation in the stirring effect of the lubricating powder, and part of the lubricating powder ash is precipitated at the bottom of the cylinder, which in turn causes a deviation in the uniformity of heating. Secondly, when the lubricating powder is stirred by the auger in the powder cylinder, there are impurities and debris inside, which affects the purity and quality of the lubricating powder without filtration. Summary of the invention

[0005] In order to overcome the defects of the prior art, a drying device capable of uniform heating is provided to solve the problems raised by the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, a drying device that can be evenly heated is provided, comprising: an equipment support and a filtering mechanism, a powder barrel is provided on the inner side of the equipment support, a heating barrel is provided on the outer side of the powder barrel, an inner shaft is provided inside the powder barrel, a spiral blade is connected to the outer side of the inner shaft, and a first motor is connected to one end of the inner shaft, a gear ring is provided on the outer wall of the powder barrel, a main gear is meshed on the outer side of the gear ring, and the main gear is connected to the second motor through an internal gear shaft, the heating barrel is rotatably connected to the outer side of the powder barrel, and a water flow chamber is provided inside the heating barrel, the filtering mechanism is provided on the lower side of the discharge port of the powder barrel, and the filtering mechanism comprises a filter box, and a filter screen is provided inside the filter box.

[0007] Furthermore, outer shafts are provided at both ends of the powder cartridge, and a bearing is provided inside the outer shaft at one end, and the inner shaft rotates the bearing.

[0008] Furthermore, a water inlet and a water outlet are provided on the outside of the heating cylinder, and a wire tube and a heater are connected to the upper side of the heating cylinder, and a power line inside the wire tube is connected to an electric heating plate arranged inside the water flow cavity.

[0009] Furthermore, rotating seals are provided at both ends of the heating cylinder, and the rotating seals are rotatably engaged with an annular groove provided on the outer wall of the powder cylinder.

[0010] Furthermore, a receiving hopper is provided at the upper end of the filter box, and the receiving hopper is located below the discharge port of the powder cylinder, and a guide plate is provided below the receiving hopper and inside the filter box.

[0011] Furthermore, a partition is provided inside the filter box, and a slide plate is slidably connected inside the partition, and a telescopic rod is provided on the lower side of the slide plate.

[0012] Furthermore, one end of the filter is hinged to the inner wall of the filter box, and the other end of the filter is inserted into the partition and located at the upper end of the slide. At the same time, a finished product box and a filter residue box are respectively provided on both sides of the partition.

[0013] The beneficial effects of the present invention are:

[0014] 1. By utilizing the meshing of the gear ring on the outside of the powder tube and the main gear and the outer shaft, the second motor drives the main gear and then drives the powder tube to rotate, and at the same time, the first motor is started to drive the inner shaft to rotate, thereby achieving the effect of uniformly stirring the lubricating powder inside the powder tube, preventing the lubricating powder from carrying a small amount of precipitation at the bottom of the powder tube, thereby improving the uniformity of heating and the drying effect;

[0015] 2. The filter box and receiving hopper included in the filtering structure are used to transport the dried lubricating powder to the inside of the filter box, and then filter it through the filter screen. The filtered lubricating powder falls into the finished product box, and the impurities are trapped on the filter screen. Then, the filter screen is pushed downward by the electric push rod on the upper side of the filter screen to an inclined state, so that the impurities slide down from one end of the filter screen into the filter residue box, thereby achieving a filtering effect and ensuring the purity and quality of the lubricating powder.

[0028] Specifically, the outer shaft 25 is rotatably connected to the inner wall of the equipment bracket 1, and a temperature sensor is provided inside the heating tube 3.

[0029] Specifically, the electric heater is inserted into the water flow cavity 31 inside the heating tube 3 , and the hot water inside the water flow cavity 31 directly contacts the outer wall of the powder tube 2 , while both ends of the water flow cavity 31 are sealed by the rotating seal 27 .

[0030] It should be noted that the rotary seal 27 is a dynamic seal structure under the prior art, mainly composed of a sliding ring filled with polytetrafluoroethylene and a rubber O-ring providing elasticity, and is used to seal a rod, shaft, pin or rotary joint with rotating or swinging motion.

[0031] As a preferred embodiment, the rotary seal 27 is provided to facilitate the rotary connection between the powder cylinder 2 and the heating cylinder 3 and to achieve the sealing effect on both ends of the water flow chamber 31 .

[0032] As a preferred embodiment, the heating tube 3 is conveniently fixed to the lower side of the top beam of the equipment support 1 through the wire tube 33, and the power line is conveniently passed through the wire tube 33 to connect the heater 32 and the electric heating plate.

[0033] like Figure 1 and Figure 5In the figure, a receiving hopper 42 is provided at the upper end of the filter box 41, and the receiving hopper 42 is located at the lower side of the discharge port of the powder tube 2, and a guide plate 43 is provided at the lower side of the receiving hopper 42 and on the inner side of the filter box 41, a partition 44 is provided inside the filter box 41, and a slide plate 441 is slidably connected inside the partition 44, and a telescopic rod 442 is provided on the lower side of the slide plate 441, one end of the filter screen 45 is hinged to the inner wall of the filter box 41, and the other end of the filter screen 45 is inserted into the partition 44 and located at the upper end of the slide plate 441, and a finished product box 46 and a filter residue box 47 are respectively provided on both sides of the partition 44.
