Description

Technical Field

[0001] The utility model belongs to the technical field of salt particle drying, in particular to a drying device for wet salt. Background Art

[0002] Refined salt, common salt includes coarse salt and sun-dried fine salt. Refined salt is made from underground natural brine, brine obtained by rock salt solution mining and brine made by dissolving coarse salt. Soluble impurities are removed by chemical methods, clarified, and then evaporated, crystallized, dehydrated, dried and screened.

[0003] At present, although stirring or vibration is widely used as the main operating method of drying equipment in the production process of refined salt in order to enhance the drying effect, these methods often fail to maximize the contact area between salt particles and hot air in actual applications. Instead, they may cause the flow of hot air to be restricted due to obstacles during the operation, which in turn seriously affects the smooth discharge of subsequent water vapor. This not only reduces the drying efficiency, but may also have an adverse effect on the quality of refined salt.

[0004] Therefore, it is very necessary to invent a drying device for wet salt. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a wet salt drying device, including a tumble drying mechanism, a dryer, an exhauster and a driving motor, wherein the dryer, the exhauster and the driving motor are all fixedly mounted on the outside of the tumble drying mechanism, and two driving motors are provided; the dryer and the exhauster are symmetrically fixedly mounted at both ends of the tumble drying mechanism;

[0006] The tumbling drying mechanism comprises a casing, a material port, a belt rack, a tumbling mechanism and a transmission belt. Two material ports are fixedly mounted on the casing, the belt racks are fixedly mounted at both ends of the casing, the dryer and the exhauster are fixedly mounted on the two belt racks, and the driving motor is also fixedly mounted; the tumbling mechanism is rotatably mounted in the casing and the belt rack; the transmission belt is mounted on the belt pulley in the tumbling mechanism and the belt rack;

[0007] The rolling mechanism comprises a rotating disk, a rolling lifting plate and a bumping plate. The rotating disk is rotatably installed in the casing and the belt frame through a bearing; the driving belt is assembled on the rotating disk; two rotating disks are provided, and the rolling lifting plates and the bumping plates are fixedly installed on the two rotating disks.

[0008] Preferably, the casing is fixedly provided with two material ports, namely a discharge port and a feed port; the inner wall of the casing is in contact with the tumbling plate, which is a twisted plate body having a spiral wave-like twist and presents a non-planar shape as a whole. The tumbling plate allows the salt particles to be driven to move upward in an arc trajectory, and when reaching a certain high point, they fall downward.

[0009] Preferably, a belt pulley is rotatably mounted inside the belt frame, and the belt pulley is fixedly connected to an output end of the driving motor fixedly mounted outside, so as to drive the rotating disk to rotate.

[0010] Preferably, a plurality of the knock plates are provided and distributed in a circular array, the knock plates are located on the inner side of the rolling and lifting plates, the knock plates are arched plates, and there is a spacing between the knock plates to allow salt particles to pass through.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model abandons the traditional commonly used drying methods such as stirring and vibration, and instead introduces an innovative "stir-frying" mechanism to significantly enhance the drying effect. This mechanism uses a carefully designed structure to make the salt particles rise along an arc trajectory under the pushing action, and fall naturally after reaching the appropriate high point position. This movement mode ensures that the salt particles and the hot air are fully and efficiently contacted, thereby significantly improving the drying efficiency.

[0013] Importantly, since the salt particles are mainly accumulated at the bottom of the device, the hot air can flow freely in the middle and upper parts of the device without being blocked. This design not only ensures smooth air circulation, but also effectively enhances the drying effect of the salt particles and avoids the problem of uneven drying caused by the obstruction of hot air flow.

[0014] In addition, when the salt particles collide with the collision plate during the falling process, this collision can not only break up the agglomerated salt particles and prevent agglomeration during the drying process, but also further increase the contact area between the salt particles and the hot air, promote the rapid evaporation of water, and thus further improve the drying effect.

[0022] As attached Figure 1 To Attachment Figure 3 As shown:

[0023] The utility model provides a wet salt drying device, comprising a tumble drying mechanism 1, a dryer 2, an exhauster 3 and a driving motor 4, wherein the dryer 2, the exhauster 3 and the driving motor 4 are all fixedly mounted outside the tumble drying mechanism 1, and there are two driving motors 4; the dryer 2 and the exhauster 3 are symmetrically fixedly mounted at both ends of the tumble drying mechanism 1. A fan is installed inside the exhauster 3, which is used to discharge the internal water vapor to the outside.

[0024] The tumbling drying mechanism 1 includes a housing 11, a material port 12, a belt rack 13, a tumbling mechanism 14 and a transmission belt 15. Two material ports 12 are fixedly installed on the housing 11, and the belt racks 13 are fixedly installed at both ends of the housing 11. The dryer 2 and the exhauster 3 are fixedly installed on the two belt racks 13, and the driving motor 4 is also fixedly installed; the tumbling mechanism 14 is rotatably installed in the housing 11 and the belt rack 13; the transmission belt 15 is mounted on the belt pulley in the tumbling mechanism 14 and the belt rack 13. The tumbling drying mechanism 1 can realize that the salt particles rise along an arc trajectory and fall naturally after reaching an appropriate high point. This movement mode ensures that the salt particles are in full and efficient contact with the hot air, thereby significantly improving the drying efficiency.

[0025] The tumbling mechanism 14 includes a rotating disk 141, a tumbling lifting plate 142 and a bumping plate 143. The rotating disk 141 is rotatably installed in the casing 11 and the belt frame 13 through a bearing; the driving belt 15 is mounted on the rotating disk 141; two rotating disks 141 are provided, and the tumbling lifting plates 142 and the bumping plates 143 are fixedly installed on the two rotating disks 141. The tumbling mechanism 14 pushes the salt particles through the rotating motion, so that the salt particles rise along an arc trajectory under the pushing action.

[0026] Embodiment 1:

[0027] Specifically, two material ports 12 are fixedly installed on the casing 11 as a discharge port and a feed port; the inner wall of the casing 11 contacts the tumbling shoveling plate 142, which is a twisted plate body with a spiral wave-like twist and a non-planar shape as a whole. The tumbling shoveling plate 142 allows the salt particles to move upward in an arc trajectory, and when they reach a certain high point, they fall downward. In the drying process, the special shape of the tumbling shoveling plate 142 plays a vital role. It can effectively drive the wet salt particles to move upward to form a stable arc trajectory. When the salt particles are lifted to a suitable high point, they will naturally fall downward due to the effect of gravity. This continuous tumbling and falling process not only greatly increases the contact area and time between the salt particles and the hot air, but also promotes the rapid evaporation of water, thereby significantly improving the drying effect.

[0028] Specifically, a belt pulley is rotatably installed inside the belt frame 13, and the belt pulley is fixedly connected to the output end of the driving motor 4 fixedly installed outside, and the belt pulley is driven to rotate through the power output of the motor 4. The belt pulley is connected to the rotating disk 141 through a transmission belt 15. When the belt pulley rotates, the transmission effect of the transmission belt 15 drives the rotating disk 141 to rotate.

[0029] Specifically, there are several collision plates 143 distributed in a circular array. The collision plates 143 are located on the inner side of the rolling and lifting plates 142. The collision plates 143 are arched plates. The shape not only enhances its structural strength, but also enables the salt particles to effectively collide with the collision plates when falling downward. During the collision process, the agglomerated salt particles will be broken, thereby preventing the agglomeration phenomenon that may occur during the drying process. There are appropriate spacings between the collision plates 143, which allow the wet salt particles to pass through and continue to participate in the rolling and falling process after the collision. At the same time, these spacings also form hot air channels, allowing hot air to flow smoothly, further improving the drying effect.

[0030] Embodiment 2:

[0031] The wet salt particles first enter the housing 11 of the tumble drying mechanism 1 through the feed port. At this time, two drive motors 4 start working, which are respectively installed at the two ends of the tumble drying mechanism 1, and drive the rotating disk 141 to rotate through the belt pulley and the transmission belt 15 in the belt frame 13. The rotating disk 141 is equipped with a tumble picker plate 142 and a bump plate 143. When the rotating disk 141 rotates, the tumble picker plate 142 uses its spiral wave-like twisted design to push the salt particles to rise along an arc trajectory, and naturally fall after reaching a high point. This continuous tumbling and falling process greatly increases the contact area and time between the salt particles and the hot air, and promotes the rapid evaporation of water. At the same time, the dryer 2 provides hot air to the inside of the tumble drying mechanism 1 to dry the tumbled salt particles. The exhauster 3 works through the fan installed inside it to discharge the water vapor generated during the drying process in time to maintain the stability of the drying environment. During the tumbling drying process, the collision plate 143 collides with the salt particles, effectively breaking up the possible lumps, further improving the drying effect. Finally, the dried salt particles are discharged through the discharge port, completing the entire drying process.

[0032] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
