Description

Technical Field

[0001] The utility model relates to the technical field of wettable powder production, in particular to a drying device for wettable powder production. Background Technique

[0002] The production of wettable powder includes processes such as mixing, pulverizing, and packaging. Among them, an air jet mill is used in the pulverizing process, which requires a large amount of compressed air. Most of the compressed air is prepared by a compressed air dryer to ensure the dryness of the compressed air. The prepared compressed air is stored in a gas storage tank for use. Some compressed air dryers still contain some moisture and oil and gas in the prepared compressed air, which will affect the pulverizing effect of the wettable powder and cause the wettable powder to contain moisture. Therefore, drying treatment is required.

[0003] After retrieval: A drying device for wettable powder production with the patent number CN214950339U includes a drying housing. Feed pipes communicating with it are fixedly connected to the left and right side walls of the drying housing, and a discharge pipe communicating with it is fixedly connected to the lower end of the drying housing. A strip-shaped housing is fixedly connected to the upper end of the drying housing, a driving motor is fixedly connected to the upper end of the strip-shaped housing, a vertical rotating shaft is fixedly connected to the output end of the driving motor, and the lower end of the rotating shaft extends into the drying housing. A mixing and heating mechanism for drying the powder is arranged on the outer side wall of the rotating shaft in the drying housing.

[0004] However, the above-mentioned drying device for wettable powder production still has deficiencies. The mixing and heating mechanism is inconvenient for mobile stirring and mixing, resulting in a limited stirring and mixing area, reducing the uniformity and comprehensiveness of the drying and mixing of the wettable powder, easily causing local drying failure, and reducing the drying effect. Therefore, we propose a drying device for wettable powder production to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the above-mentioned drawbacks, and a drying device for wettable powder production is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A drying device for wettable powder production includes a drying box for drying wettable powder. A partition is fixedly connected inside the drying box. A mobile stirring and mixing mechanism for stirring wettable powder is arranged on the drying box above the partition. A rectangular opening is formed at the top of the partition, and a sealing and shielding mechanism is arranged between the partition and the rectangular opening. Heating plates are fixedly connected to the inner walls on both sides of the drying box. A feed pipe is fixedly communicated with one side of the drying box, and an air outlet pipe is fixedly communicated with the other side of the drying box.

[0008] Specifically, the mobile stirring and mixing mechanism includes a servo motor fixedly connected to one side of the drying oven, and racks fixedly connected to the inner walls on both sides of the drying oven.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Referring to Figures 1-5 , a drying device for the production of wettable powder includes a drying oven 1 for drying wettable powder. A partition board 20 is fixedly connected inside the drying oven 1. A mobile stirring and mixing mechanism for stirring wettable powder is arranged on the drying oven 1 above the partition board 20.

Heating plates 19 are fixedly connected to both inner walls of the drying oven 1. A feed pipe 2 is fixedly communicated with one side of the drying oven 1, and an air outlet pipe 5 is fixedly communicated with the other side of the drying oven 1.

[0026] Furthermore, the mobile stirring and mixing mechanism includes a servo motor 3 fixedly connected to one side of the drying box 1, and racks 9 fixedly connected to the inner walls on both sides of the drying box 1. A reciprocating lead screw 6 is fixedly connected to the output shaft of the servo motor 3. A moving seat 7 is sleeved on the outer side of the reciprocating lead screw 6 in a threaded manner. A stirring shaft 14 is rotatably connected to the bottom of the moving seat 7. Two cross stirring rods 15 are fixedly connected to both sides of the stirring shaft 14. Two vertical stirring rods 16 are fixedly connected between the two cross stirring rods 15 on the same side. A gear 11 is fixedly sleeved on the outer side of the stirring shaft 14. The gear 11 meshes with the rack 9. By driving the rotation of the reciprocating lead screw 6 with the servo motor 3, the reciprocating lead screw 6 drives the left and right reciprocating movement of the moving seat 7. The moving seat 7 drives the left and right reciprocating movement of the stirring shaft 14, the cross stirring rods 15 and the vertical stirring rods 16, so as to achieve the effect of stirring and mixing. At the same time, the stirring shaft 14 drives the left and right reciprocating movement of the gear 11. Under the action of the fixedly arranged rack 9, the gear 11 will rotate self - clockwise. The gear 11 will roll left or right along the rack 9. The gear 11 drives the rotation of the stirring shaft 14, the cross stirring rods 15 and the vertical stirring rods 16, driving the cross stirring rods 15 and the vertical stirring rods 16 to rotate while moving left and right reciprocally, achieving the effect of mobile stirring, making the stirring and mixing area larger, improving the uniformity and comprehensiveness of the drying and mixing of the wettable powder, and greatly improving the drying effect.

[0027] Furthermore, a limiting groove is opened on the inner wall of the top of the drying box 1. A limiting block 8 is fixedly connected to the top of the moving seat 7. The limiting block 8 is slidably sleeved in the limiting groove, which is convenient for guiding and limiting the moving seat 7 so that it does not rotate together with the reciprocating lead screw 6.

[0028] Furthermore, two cavities 22 are opened in the partition plate 20. The sealing and shielding mechanism includes a rotating shaft 10 rotatably connected to the inner walls on the front and rear sides of the cavity 22, and a slider 13 slidably sleeved in the rectangular opening 23. The stirring shaft 14 is rotatably sleeved in the slider 13. A winding disc 24 is fixedly sleeved on the outer side of the rotating shaft 10. A shielding cloth 21 is movably wound around the outer side of the winding disc 24. The two shielding cloths 21 are respectively fixedly connected to both sides of the slider 13. Torsion springs 18 are fixedly connected to the front and rear sides of the winding disc 24. The mutually remote ends of the two torsion springs 18 are respectively fixedly connected to the inner walls on the front and rear sides of the cavity 22. At the same time, when the stirring shaft 14 moves, it will automatically drive the left and right reciprocating movement of the slider 13. The slider 13 will drive the two shielding cloths 21 to move. The elongation of one shielding cloth 21 will drive the reverse rotation and unwinding of the winding disc 24 and cause the torsion spring 18 to twist and store energy. Under the torsion of the torsion spring 18, the other shielding cloth 21 will automatically retract under the forward rotation and winding of the winding disc 24. Thus, the two shielding cloths 21 can always shield and seal the rectangular opening 23, preventing the wettable powder from being thrown above the partition plate 20 during stirring, avoiding waste, and at the same time preventing the components above the partition plate 20 from being polluted and blocked, etc., which affects the normal operation.

[0030] Furthermore, both torsion springs 18 are sleeved on the outer side of the rotating shaft 10, through holes are formed between the cavity 22 and the rectangular opening 23, and the two shielding cloths 21 are respectively slidably sleeved in the corresponding through holes, which is convenient for guiding the shielding cloths 21 and making their movement more stable and smooth.

[0031] Furthermore, two flow guiding plates 17 are fixedly connected to the bottom inner wall of the drying box 1, and a discharge pipe 4 is fixedly communicated with the bottom of the drying box 1. An electromagnetic valve is arranged in the discharge pipe 4, which is beneficial to discharging the dried wettable powder.

[0032] In the present utility model, during use, the wettable powder is poured into the drying box 1 from the feed pipe 2, the servo motor 3 and the heating plate 19 are started. Through the heating plate 19, the drying box 1 can be heated to heat and dry the wettable powder. At the same time, the rotation of the reciprocating lead screw 6 is driven by the servo motor 3, the reciprocating lead screw 6 drives the left and right reciprocating movement of the moving seat 7, the moving seat 7 drives the left and right reciprocating movement of the stirring shaft 14, the horizontal stirring rod 15 and the vertical stirring rod 16, so as to achieve the effect of stirring and mixing. At the same time, the stirring shaft 14 drives the left and right reciprocating movement of the gear 11. Under the action of the fixedly arranged rack 9, the gear 11 will rotate automatically, and the gear 11 will roll left or right along the rack 9. The gear 11 drives the rotation of the stirring shaft 14, the horizontal stirring rod 15 and the vertical stirring rod 16, driving the horizontal stirring rod 15 and the vertical stirring rod 16 to rotate and move left and right reciprocally, which can achieve the effect of mobile stirring, making the stirring and mixing area larger, improving the uniformity and comprehensiveness of the drying and mixing of the wettable powder, greatly improving the drying effect. At the same time, when the stirring shaft 14 moves, it will automatically drive the left and right reciprocating movement of the slider 13, and the slider 13 will drive the two shielding cloths 21 to move. The elongation of one shielding cloth 21 will drive the reverse rotation and unwinding of the winding disc 24 and make the torsion spring 18 twist and store energy. Under the torsion force of the torsion spring 18, the other shielding cloth 21 will automatically retract under the forward rotation and winding of the winding disc 24. Thus, the two shielding cloths 21 can always shield and seal the rectangular opening 23, preventing the wettable powder from being thrown above the partition plate 20 during stirring and causing waste, and at the same time avoiding pollution and blockage of the components above the partition plate 20 and affecting the normal operation. When drying is completed, the electromagnetic valve in the discharge pipe 4 is opened, and under the diversion of the flow guiding plate 17, the wettable powder can be discharged from the discharge pipe 4.
