DETAILED DESCRIPTION

[0029] Although the present invention may be described with respect to a particular application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0030] A device for drying sticky wet powdered mineral powder, such as Figure 1-Figure 4 As shown, it includes a base plate 1, a heating cylinder 2, a driving motor 3, a stirring assembly and a cleaning assembly. The heating cylinder 2 is connected to the top of the base plate 1, and the driving motor 3 is installed in the middle of the left side of the heating cylinder 2. The right side of the heating cylinder 2 is open. The output shaft of the driving motor 3 is provided with a stirring assembly, and the stirring assembly is used to stir the mineral powder. The heating cylinder 2 is provided with a cleaning mechanism for cleaning the mineral powder.

[0031] like Figure 2 and Figure 3 As shown, the stirring assembly includes a stirring rod 41 and a stirring blade 42. The stirring rod 41 is connected to the output shaft of the driving motor 3. The stirring rod 41 extends into the middle of the heating cylinder 2. The stirring rod 41 is rotatably connected to the heating cylinder 2. Three stirring blades 42 are evenly spaced along the circumferential direction on the stirring rod 41. The rotation of the stirring rod 41 can drive the stirring blades 42 to rotate, thereby stirring the mineral powder in the heating cylinder 2.

[0032] like Figure 3 and Figure 4As shown, the cleaning mechanism includes a driving cylinder 51, a connecting block 52, a swivel 53, a connecting rod 54, a scraper plate 55 and a cover 56. The driving cylinder 51 is installed in the middle of the top of the heating cylinder 2, and the connecting block 52 is connected to the telescopic rod of the driving cylinder 51. The bottom of the connecting block 52 is connected to the cover 56, and the cover 56 can cover the open position on the right side of the heating cylinder 2. A feeding port is opened at the lower part of the cover 56. The left side of the cover 56 is rotatably connected to the swivel 53, and the front and rear sides of the swivel 53 are connected to the connecting rod 54. A scraper plate 55 is connected between the left sides of the two connecting rods 54. The scraper plate 55 is sleeved on the stirring rod 41 and the stirring blade 42 and is slidably connected to the stirring rod 41 and the stirring blade 42, so that the scraper plate 55 can scrape off the mineral powder attached to the stirring rod 41 and the stirring blade 42 when rotating.

[0033] When it is necessary to dry the sticky powder, the device can be used. When in use, the powder is added into the heating cylinder 2 through the feed port. After the addition is completed, the heating cylinder 2 is controlled to heat the inside thereof. During the heating process, the driving motor 3 can be controlled to drive the stirring rod 41 and the stirring blade 42 to rotate. When the stirring blade 42 rotates, it can stir the powder to assist in breaking up the powder to dry the powder. After the processing is completed, the telescopic rod of the driving cylinder 51 can be controlled to extend to drive the connecting block 52 to move to the right. When the connecting block 52 moves to the right, it drives the sealing cover 56 to move to the right. Move right, the cover 56 can open the heating tube 2 when moving to the right, and at the same time drive the rotating ring 53, the connecting rod 54 and the scraper plate 55 to move to the right, and the scraper plate 55 can scrape off the powder attached to the stirring rod 41, the stirring blade 42 and the inner wall of the heating tube 2 when moving, and then new powder can be added for drying. In this way, the device can be used to dry the sticky powder, and after the treatment, the powder inside the heating tube 2 can be scraped off to avoid the subsequent addition of other types of powders, which will cause the subsequent powder to mix with the original powder and cause powder doping.

[0034] like Figure 5 and Figure 6 As shown, a discharging mechanism is also included, and the discharging mechanism includes a discharging hopper 61, a servo motor 62 and a crushing gear shaft 63. The discharging hopper 61 is rotatably connected to the right side of the top of the bottom plate 1, and a discharging port is arranged at the lower right part of the discharging hopper 61. The lower right part of the discharging hopper 61 is rotatably connected to two upper and lower crushing gear shafts 63, and the two crushing gear shafts 63 are meshed with each other. The crushing gear shafts 63 are aligned with the discharging port of the discharging hopper 61. A servo motor 62 is installed on the discharging hopper 61, and the output shaft of the servo motor 62 is connected to the crushing gear shaft 63 above.

[0035] like Figure 5 As shown, an inclined plate 7 is also included, and the inclined plate 7 is connected to the right side of the discharge hopper 61.

[0036] The powder discharged from the heating cylinder 2 will fall into the discharge hopper 61. The inclined plate 7 can block the powder to prevent the powder from directly sliding down from the discharge hopper 61. The powder will enter between the two crushing gear shafts 63 through the discharge port of the discharge hopper 61. Then, the servo motor 62 can be controlled to drive the two crushing gear shafts 63 to rotate, thereby crushing part of the agglomerated powder to prevent the powder from agglomerating together and affecting the use.

[0037] like Figure 7 As shown, a closing mechanism is also included, which includes an electric push rod 71, an L-shaped connecting plate 72, a slide bar 73, a blocking plate 74 and an elastic member 75. An electric push rod 71 is installed on the upper right side of the cover 56, and an L-shaped connecting plate 72 is connected to the telescopic rod of the electric push rod 71. The slide bar 73 is slidably connected to the L-shaped connecting plate 72. An elastic member 75 is connected between the slide bar 73 and the L-shaped connecting plate 72, and the elastic member 75 is a tension spring. A blocking plate 74 is connected to the left side of the slide bar 73, and the blocking plate 74 blocks the feed port. The top of the blocking plate 74 and the upper side wall of the feed port are both inclined and the inclined parts fit each other. When the blocking plate 74 moves upward, it will be squeezed by the inclined part of the feed port, so that the blocking plate 74 moves to the right.

[0038] Initially, the telescopic rod of the electric push rod 71 is in an extended state, and the blocking plate 74 blocks the feed port. When powder needs to be added, the telescopic rod of the electric push rod 71 can be controlled to retract to drive the blocking plate 74 to move upward. When moving upward, the blocking plate 74 will move to the right through the blocking plate 74 and the inclined surface at the feed port. The blocking plate 74 moves to the right and drives the sliding rod 73 to move to the right. The elastic member 75 is stretched, and the blocking plate 74 moves up to expose the feed port. At this time, powder can be added. After adding, the telescopic rod of the electric push rod 71 can be controlled to extend to drive the blocking plate 74 to block the feed port, so that drying can be carried out. During the drying process, the feed port can be blocked to prevent powder from being scattered through the feed port.

[0039] like Figure 8-Figure 10 As shown, a cleaning mechanism is also included, which includes a sliding rod 81, a guide sleeve 82, a cleaning nozzle 83, an injection pipe 84, a guide frame 85 and a connecting rod 86. The sliding rod 81 is slidably connected to the telescopic rod of the driving cylinder 51, and the guide sleeve 82 is connected to the front and rear sides of the sliding rod 81. The front and rear sides of the top of the heating cylinder 2 are connected to the guide frame 85. The connecting rod 86 is slidably and rotatably connected to the guide frame 85. A cleaning nozzle 83 is connected between the left sides of the two connecting rods 86, and the front side of the top of the cleaning nozzle 83 is connected to the injection pipe 84.

[0040] like Figure 8-Figure 10As shown, a driving mechanism is also included, and the driving mechanism includes a dual-axis motor 91, a winding wheel 92 and a connecting rope 93. The dual-axis motor 91 is installed on the right side of the shell of the electric push rod 71, and the two output shafts of the dual-axis motor 91 are connected to the winding wheel 92. The connecting rope 93 is wound on the winding wheel 92, and the connecting rope 93 passes through the guide sleeve 82 and is connected to the cleaning nozzle 83.

[0041] During the operation, the water pipe can be connected to the injection pipe 84. After drying, when the telescopic rod of the driving cylinder 51 is extended, the telescopic rod of the driving cylinder 51 will contact the sliding rod 81 and squeeze the sliding rod 81 to move to the right. When the sliding rod 81 moves, it will drive the guide sleeve 82 to move together. When the cover 56 moves, it can drive the cleaning nozzle 83 to move to the right through the dual-axis motor 91 and the connecting rope 93. When the cleaning nozzle 83 moves, it will drive the connecting rod 86 to move together. When the telescopic rod of the driving cylinder 51 is fully extended, the cleaning nozzle 83 can be moved to the right together. The cleaning nozzle 83 is located between the scraper plate 55 and the sealing cover 56. At this time, the dual-axis motor 91 can be controlled to drive the winding wheel 92 to rotate in the opposite direction to loosen the connecting rope 93, and at the same time, the water pipe can be controlled to pass water. When the connecting rope 93 is loosened, the cleaning nozzle 83 will fall under the action of gravity. When the cleaning nozzle 83 falls, water can be sprayed out through the cleaning nozzle 83. The sprayed water can be sprayed on the sealing cover 56 and the scraper plate 55 respectively, thereby cleaning the sealing cover 56 and the scraper plate 55 to avoid mineral powder residue on the sealing cover 56 and the scraper plate 55.

[0042] like Fig.11 As shown, it also includes a lifting mechanism, which includes a support plate 101, a lifting cylinder 102 and a lifting rail 103. The support plate 101 is rotatably connected to the left side of the bottom of the base plate 1, and the support plate 101 is located below the base plate 1. A lifting cylinder 102 is installed in the middle of the right side of the support plate 101, and the lifting rail 103 is connected to the right side of the bottom of the heating tube 2. An extrusion frame 104 is connected to the telescopic rod of the lifting cylinder 102, and the extrusion frame 104 is located in the lifting rail 103.

[0043] When adding mineral powder, the telescopic rod of the lifting cylinder 102 can be controlled to extend to drive the extrusion frame 104 to move upward. When moving upward, the extrusion frame 104 will squeeze the lifting track 103, thereby moving the lifting track 103 upward. When moving upward, the lifting track 103 will drive the heating cylinder 2 and the bottom plate 1 to tilt, so that the mineral powder can slide down along the inclined heating cylinder 2, so as to facilitate the addition of mineral powder.

[0044] like Fig.12 As shown, a toggle plate 11 is also included. The front and rear sides of the transmission shaft of the discharge hopper 61 are connected with the toggle plates 11. The discharge hopper 61 can be toggled to shake through the toggle plates 11, thereby assisting in the discharge and processing of the mineral powder.
