Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization paste production, in particular to a preparation device for desulfurization paste. Background Art

[0002] Desulfurization paste is also called flue gas desulfurization gypsum, sulfur gypsum or FGD gypsum. Its main component is calcium sulfate dihydrate, the same as natural gypsum. It is widely used in building materials and other industries. The use of desulfurization gypsum is usually to remove water from the desulfurization gypsum and crush it into powder.

[0003] In the drying process of the existing desulfurization paste preparation equipment, hot air is generally passed through the surface of the desulfurization paste to simply dry the desulfurization paste. Specifically, a drying device for preparing desulfurized gypsum disclosed in a Chinese patent (Announcement No.: CN216924941U) heats the air through an electric heating plate and an electric heating network to increase the temperature in the device. The hot air then passes through the gypsum raw material to perform an evaporation treatment. The desulfurized gypsum particles are gradually evaporated by the hot air, and the humidity gradually decreases. Finally, the desulfurized gypsum raw material is dried. However, this drying method causes the temperature of the side of the desulfurized paste close to the hot air to be higher, and the temperature of the side away from the hot air to be lower, resulting in the desulfurized paste not being heated evenly, which leads to uneven drying of the desulfurized paste and adhesion during the powdering process, which seriously affects the forming of the powder and affects the product quality.

[0004] In view of this, in order to address the above-mentioned deficiencies, the utility model improves and optimizes the desulfurization paste preparation equipment in the prior art, and develops a desulfurization paste preparation equipment. Summary of the invention

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 4 , the utility model provides a technical solution:

[0026] A desulfurization paste preparation device comprises a base 1, a fixed platform 2 is fixedly connected to one side of the top of the base 1, a motor 3 is fixedly connected to the inner cavity of the fixed platform 2, a feed hopper 10 is fixedly connected to the top of the fixed platform 2, a feed pipe 11 is fixedly connected to the bottom of the feed hopper 10, the feed pipe 11 passes through one side of the fixed platform 2 and extends to the inner cavity of the fixed platform 2, an output shaft of the motor 3 is fixedly connected to a rotating shaft 4, the other end of the rotating shaft 4 is fixedly connected to a drying cylinder 6, the drying cylinder 6 is inclined at an angle of 5° to 10° with the horizontal plane, the outer surface of the drying cylinder 6 is rotatably connected to the inner wall of a roller ring 7, the bottom of the roller ring 7 is fixedly connected to a bracket 5, and there are two roller rings 7, two The roller rings 7 are symmetrically distributed along the central axis of the drying cylinder 6, the bottom of the bracket 5 is fixedly connected to the top of the base 1, a feed port 12 is provided at one end of the drying cylinder 6 close to the fixed platform 2, a discharge port 13 is provided at the other end of the drying cylinder 6, an exhaust hole 15 is provided at the circumferential bottom of the drying cylinder 6 located at the discharge port 13, a hot air furnace 8 is provided on the side of the drying cylinder 6 away from the fixed platform 2, the bottom of the hot air furnace 8 is fixedly connected to the base 1, a hot air pipe 9 is fixedly connected to one side of the hot air furnace 8, the other end of the hot air pipe 9 passes through the fixed frame 22 and the drying cylinder 6 and extends into the drying cylinder 6, the fixed frame 22 is fixedly connected to the top of the base 1, and the hot air pipe 9 is fixedly connected to the center of the side wall of the drying cylinder 6.

[0027] By adopting the above technical solution, the operator adds the desulfurization paste into the feed hopper 10, so that the desulfurization paste enters the drying cylinder 6 through the feed port 12 along the feed pipe 11. After the desulfurization paste to be dried is placed in the drying cylinder 6, the feed port 12 and the discharge port 13 are blocked to prevent the desulfurization paste from rolling out of the drying cylinder 6 as the drying cylinder 6 rotates, and the hot air furnace 8 is turned on to make the hot air furnace 8 blow hot air into the drying cylinder 6 through the hot air pipe 9, and then the motor 3 is turned on. The motor 3 drives the rotating shaft 4 fixed with the output shaft to rotate, and the rotating shaft 4 drives the drying cylinder 6 to rotate. The drying cylinder 6 rotates in the roller rings 7 symmetrically distributed on both sides. The roller rings 7 cooperate with the bracket 5 to support the drying cylinder 6. The desulfurization paste in the drying cylinder 6 rotates with the drying cylinder 6 and rolls in the inner cavity of the drying cylinder 6. The drying cylinder 6 is inclined at an angle of 5° to 10° with the horizontal plane, so that the desulfurization paste rotates. During the process, it gradually moves to the other end of the drying cylinder 6 so that the desulfurization paste can be evenly heated and dried. After the desulfurization paste is dried, the operator opens the discharge port 13 and takes out the desulfurization paste accumulated on one side of the drying cylinder 6 from the discharge port 13. The water vapor generated by the desulfurization paste during the drying process is discharged through the exhaust hole 15. The circumferential bottom of the exhaust hole 15 is fixedly connected with filter cotton to prevent the desulfurization paste from being discharged from the exhaust hole 15. The exhaust hole 15 can prevent water vapor from remaining in the drying cylinder 6 and extend the drying time of the desulfurization paste. The drying cylinder 6 continuously turns and stirs the desulfurization paste to expose it to the hot air for a longer time, thereby increasing the heat and mass transfer efficiency of the hot air to the gypsum material, and can avoid uneven heating of the desulfurization paste, resulting in uneven drying of the desulfurization paste and adhesion during the powdering process, which seriously affects the forming of the powder and affects the product quality.

[0028] Specifically, Figure 3 As shown, an outer gear ring 18 is fixedly connected to the side of the drying cylinder 6 away from the fixed platform 2, and the outer edge of the outer gear ring 18 is meshed with a fixed gear 19, and a fixed shaft 20 is fixedly connected to the outer side of the fixed gear 19, and the other end of the fixed shaft 20 is rotatably connected to one side of the fixed frame 22, and the outer edge of the fixed gear 19 is meshed with an inner gear ring 21, and a stirring shaft 17 is fixedly connected to the outer side of the inner gear ring 21, and one end of the stirring shaft 17 is rotatably connected to one side of the fixed frame 22, and the other end of the stirring shaft 17 passes through the center of the side wall of the drying cylinder 6 and extends to the inner cavity of the drying cylinder 6, and a plurality of stirring blades 14 are fixedly connected to the outer surface of the stirring shaft 17, and the interior of the stirring shaft 17 is hollow, and the inner cavity of the stirring shaft 17 is sleeved with a hot air pipe 9, and the stirring shaft 17 is provided with a plurality of holes 16 on the outer surface of the inner cavity of the drying cylinder 6.

[0029] By adopting the above technical scheme, the hot air discharged from the hot air furnace 8 is discharged into the stirring shaft 17 through the hot air pipe 9, and is discharged into the drying cylinder 6 through multiple holes 16 on the outer surface of the stirring shaft 17. A filter is provided at the bottom of the hole 16 to prevent the desulfurization paste from entering the inner cavity of the stirring shaft 17. The motor 3 drives the drying cylinder 6 to rotate forward, and the drying cylinder 6 drives the outer gear ring 18 on one side to rotate synchronously. The outer gear ring 18 makes the meshing fixed gear 19 rotate forward synchronously, and the meshing inner gear ring 21 on the outer edge of the fixed gear 19 is driven to reverse. The inner gear ring 21 makes the stirring shaft 17 and the stirring blades 14 on the outer surface of the stirring shaft 17 rotate in the opposite direction to the drying cylinder 6. Through the double stirring of the drying cylinder 6 and the stirring blades 14, the desulfurization paste is evenly distributed in the drying cylinder 6, avoiding the accumulation of part of the desulfurization paste, which reduces the heat transfer efficiency of the hot air and causes the desulfurization paste to be incompletely dried.

[0030] Specifically, Figure 3 , Figure 4 As shown, the gear ratio between the inner gear ring 21 and the outer gear ring 18 is 1:2.

[0031] By adopting the above technical solution, the outer ring gear 18 rotates the fixed gear 19 to make the inner ring gear 21 rotate in the opposite direction. The gear tooth ratio of the inner ring gear 21 and the outer ring gear 18 is 1:2. The inner ring gear 21 drives the stirring shaft 17 to rotate faster in the drying cylinder 6, thereby increasing the rotation speed of the stirring blade 14 and improving the drying efficiency of the desulfurized gypsum.

[0032] Specifically, Figure 1 As shown, the blowing direction of the hot blast furnace 8 is opposite to the feeding direction of the feeding port 12 .

[0033] By adopting the above technical solution, when feeding on one side and blowing hot air on the other side, the hot air enters the drying cylinder 6 from the right side and flows along the axial direction of the drying cylinder 6, forming a relatively stable hot air flow area, so that the hot air is more evenly distributed in the drying cylinder 6, so that it can more fully cover the surface of the desulfurization paste and improve the drying effect.

[0034] Specifically, Figure 2 As shown, the stirring shaft 17 and the stirring blade 14 are connected by threads.

[0035] By adopting the above technical solution, the stirring shaft 17 and the stirring blades 14 can be disassembled from the drying cylinder 6 for regular cleaning and maintenance, thereby extending the service life of the equipment.

[0036] Working principle: The operator adds the desulfurization paste into the feed hopper 10, so that the desulfurization paste enters the drying cylinder 6 through the feed port 12 along the feed pipe 11. After the desulfurization paste to be dried is placed in the drying cylinder 6, the feed port 12 and the discharge port 13 are blocked to prevent the desulfurization paste from rolling out of the drying cylinder 6 as the drying cylinder 6 rotates, and the hot air furnace 8 is turned on. The hot air discharged from the hot air furnace 8 is discharged into the stirring shaft 17 through the hot air pipe 9, and is discharged into the drying cylinder 6 through the multiple holes 16 on the outer surface of the stirring shaft 17. A filter is provided at the bottom of the hole 16 to prevent the desulfurization paste from entering the inner cavity of the stirring shaft 17. Then the motor 3 is turned on, and the motor 3 drives the rotating shaft 4 fixed to the output shaft to rotate, and the rotating shaft 4 drives the drying cylinder 6 to rotate. The drying cylinder 6 rotates in the roller rings 7 symmetrically distributed on both sides, and the roller rings 7 cooperate with the bracket 5 to support the drying cylinder 6. The sulfur paste rotates with the drying cylinder 6 and rolls in the inner cavity of the drying cylinder 6. The drying cylinder 6 is inclined at an angle of 5° to 10° to the horizontal plane, so that the desulfurization paste gradually moves to the other end of the drying cylinder 6 during the rotation. The motor 3 drives the drying cylinder 6 to rotate forward, and the drying cylinder 6 drives the outer gear ring 18 on one side to rotate synchronously. The outer gear ring 18 makes the meshing fixed gear 19 rotate forward synchronously, and the meshing inner gear ring 21 on the outer edge of the fixed gear 19 is driven to reverse. The inner gear ring 21 makes the stirring shaft 17 and the stirring blades 14 on the outer surface of the stirring shaft 17 rotate in the opposite direction to the drying cylinder 6. Under the dual stirring of the drying cylinder 6 and the stirring blades 14, the desulfurization paste is evenly distributed in the drying cylinder 6, so that the desulfurization paste can be evenly heated and dried. After the desulfurization paste is dried, the operator opens the discharge port 13 and takes out the desulfurization paste accumulated on one side of the drying cylinder 6 from the discharge port 13.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
