[0055] The high-efficiency salt product drying system of this application will be described in detail below through the following embodiments.

[0056] Example 1:

[0057] like Figures 1-9 As shown, this embodiment proposes a high-efficiency salt product drying system, including: a frame with a worktable on it; a horizontal drying tank disposed on the worktable for heating and drying the salt product inside; a rotary drive assembly for driving the horizontal drying tank to rotate; a lifting assembly for lifting the salt product and feeding it into the horizontal drying tank; a feeding assembly connected to the output port of the horizontal drying tank for receiving the dried salt product; and a feeding assembly for conveying the salt product to the feed port of the lifting assembly.

[0058] The feeding assembly includes: a feeding frame, located on the side of the frame; a feeding hopper, located on the feeding frame, with its inlet facing upwards and its outlet facing downwards; and a feeding conveyor belt, located below the feeding hopper, for conveying the salt product discharged from the feeding hopper to the inlet of the lifting assembly.

[0059] In order to dry large quantities of salt products, the above-mentioned drying system is set up. Compared with some existing drying devices, this drying system has the advantages of high efficiency.

[0060] Specifically, the salt product is first fed into the feeding hopper using equipment such as a bucket. Under the influence of gravity, the salt product gradually flows out from the discharge port at the bottom of the hopper and falls onto the feeding conveyor belt. The feeding conveyor belt then gradually feeds the salt product into the inlet of the lifting component. Subsequently, the lifting component is activated, lifting the salt product and sending it into a horizontal drying tank at a higher position. The horizontal drying tank is activated to heat and dry the salt product inside. During this process, the horizontal drying tank rotates under the action of the rotary drive component, ensuring that the salt product inside is evenly heated and dried, and then discharged from the output port of the horizontal drying tank to the feeding component. Finally, the dried salt product is collected by the staff.

[0061] In this embodiment, it should be noted that, in order to facilitate the discharge of salt products from the output port of the horizontal drying tank, it is tilted. After the salt products enter the horizontal drying tank, the horizontal drying tank rotates under the action of the rotation drive component, causing the salt products to gradually move towards its output port. Since the horizontal drying tank is relatively long, it takes a certain amount of time for the salt products inside to move from the input port to the output port. During this time, the salt products are heated and dried completely. The dried salt products are finally discharged from the output port to the feeding component, and finally, the workers collect the dried salt products from the feeding component.

[0062] Example 2:

[0063] This embodiment is a further improvement based on Embodiment 1.

[0064] like Figures 3-5 As shown, in this embodiment, the feeding conveyor belt includes: two drive rollers mounted on the feeding frame; a conveyor belt sleeved on the two drive rollers; multiple guide wheel sets disposed along the length of the conveyor belt between the upper and lower belt surfaces for supporting and guiding the upper belt surface; and a drive roller drive unit for driving one of the drive rollers to rotate, thereby moving the conveyor belt.

[0065] The feeding frame is equipped with two crossbeams located in front of and behind the conveyor belt. The guide wheel assembly includes: a mounting frame, which is mounted on the two crossbeams; and guide wheels, at least three in number, which are mounted on the mounting frame along the width direction of the conveyor belt. The guide wheels in the middle are arranged horizontally, and the guide wheels on both sides are arranged obliquely upward. After the conveyor belt passes through the guide wheel assembly, the surface of the conveyor belt has a shape that is concave in the middle and raised on both sides.

[0066] After a large quantity of salt product is loaded into the feeding hopper, the valve at the discharge port at the bottom of the hopper opens, and the salt product gradually falls onto the feeding conveyor belt, eventually being transported from the feeding conveyor belt to the area of ​​the lifting assembly. Because the salt product has a fine granular structure, improvements were made to the existing belt conveyor to prevent it from spilling out during transport.

[0067] Specifically, the feeding conveyor belt includes: a drive roller, a conveyor belt, a drive roller drive unit, and a guide wheel assembly. The drive roller drive unit is mainly a motor, which directly drives one of the drive rollers to rotate, or drives a pulley to rotate, and then the drive belt drives the drive roller to rotate, thereby moving the conveyor belt. With the guide wheel assembly, on the one hand, the upper surface of the conveyor belt can be supported, making it more stable when transporting salt products. On the other hand, the guide wheels on the guide wheel assembly guide the conveyor belt into a concave shape. This concave shape can better receive the salt products falling from the feeding hopper, and during the movement of the conveyor belt, the salt products will always be surrounded by the two sides of the concave shape and will not spill, until they move smoothly to the feed inlet of the lifting component.

[0068] Example 3:

[0069] This embodiment is a further improvement based on any of the above embodiments.

[0070] like Figures 1-2 , Figures 6-7 As shown, in this embodiment, the horizontal drying tank is divided into fixed areas at both ends and a rotating area in the middle. The two fixed areas are fixedly set on the workbench, and the two ends of the rotating area are rotatably connected to the two fixed areas. The salt product is heated and dried in the rotating area.

[0071] The rotary drive assembly includes: a first transmission wheel, fixedly sleeved on the rotary area; a second transmission wheel, cooperating with the first transmission wheel; and a rotary drive unit for driving the second transmission wheel to rotate, thereby driving the first transmission wheel and the rotary area to rotate.

[0072] The horizontal drying tank mainly consists of two fixed areas on both sides and a rotating area in the middle. The fixed areas are installed on the workbench by a fixing frame, and the rotating area is installed between the two fixed areas. The rotating area has a sleeve structure, and there are multiple lifting ribs arranged along its length inside. When the rotating area rotates, the salt product is lifted to a certain height by the lifting ribs and then falls, so that the moisture in the salt product can evaporate quickly and thus dry it.

[0073] It should be noted that the heating of salt products can be achieved using a microwave system. A microwave generator produces microwave energy, which is then applied to the salt products to evaporate the moisture, thus drying them. The evaporated water vapor is then blown outwards by a fan. Alternatively, a heating system can be used, where a heater heats the rotating zone, and the high-temperature gas then dries the salt products.

[0074] Example 4:

[0075] This embodiment is a further improvement based on Embodiment 3.

[0076] like Figures 1-2 , Figures 6-7 As shown, in this embodiment, the first transmission wheel and the second transmission wheel are gears or friction wheels, which drive the rotating area to rotate by gear transmission or friction transmission.

[0077] By activating the rotary drive unit, the rotary drive unit drives the second transmission wheel to rotate, and then the second transmission wheel drives the first transmission wheel to rotate, thereby driving the rotating area to rotate.

[0078] In this embodiment, it should be noted that, due to the large volume of the entire horizontal drying tank, if gear transmission is used, the total weight of the horizontal drying tank and the salt products inside it may easily damage the rotary drive unit if it exceeds the load that the rotary drive unit can withstand. Therefore, a friction drive method is optimized. Specifically, a large friction roller is mounted on the rotating part, a fixed frame is set at the bottom of the rotating part, and a small friction roller is set on each side of the fixed frame. The two small friction rollers abut against the large friction roller. When the rotary drive unit drives the small friction rollers to rotate, the large friction roller also rotates simultaneously under the action of friction, thereby realizing the rotation of the rotating area.

[0079] It should be noted that, in order to improve the smoothness of rotation in the rotating area, one or two more large friction rollers can be installed, and correspondingly two or four more small friction rollers can be installed.

[0080] Example 5:

[0081] This embodiment is a further improvement based on any of the above embodiments.

[0082] like Figures 1-2 , Figures 8-9As shown, in this embodiment, the lifting assembly includes: a vertical frame; a lifting conveyor belt, which is vertically mounted on the vertical frame and has several lifting buckets for lifting the salt products, with the inlet of the lifting conveyor belt located at its lower end and its outlet located at its top; and a feeding pipe, which is inclined and has its higher end connected to the outlet of the lifting conveyor belt and its lower end connected to the inlet of the horizontal drying tank.

[0083] The discharge end of the feeding conveyor belt extends to the inlet of the lifting conveyor belt.

[0084] Due to the large size of the entire drying system and the relatively high position of the horizontal drying tank, a lifting assembly is installed to elevate and transport the salt product into the horizontal drying tank. Specifically, after the salt product enters the feeding conveyor belt from the feeding hopper, the feeding conveyor belt then sends it to a position below the lifting conveyor belt. When the lifting conveyor belt is running, the lifting buckets on it scoop up a certain amount of salt product and move upward with the lifting conveyor belt. Then, the next lifting bucket scoops up a certain amount of salt product and moves upward with the lifting conveyor belt, thus continuously lifting the salt product upward. When the lifting conveyor belt moves the lifting bucket containing the salt product to the top, the lifting bucket will flip over, and the flipped lifting bucket will throw the salt product inside into the feed pipe. The salt product in the feed pipe will gradually slide down under the action of gravity to the input port above the horizontal drying tank and enter the horizontal drying tank.

[0085] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
