Description

Technical Field

[0001] This utility model relates to the field of sea sand pretreatment technology, and in particular to a sea sand filter material dryer. Background Technology

[0002] As a filter material for construction and industry, sea sand must undergo strict cleaning and drying treatment before use. The core objective is to effectively remove moisture, reduce salt content, and lower the moisture content to a level that meets standards, so as to avoid serious engineering problems such as steel corrosion and strength reduction in applications such as concrete.

[0003] However, many current sea sand drying equipment processes separate screening and drying, with many screening mechanisms powered independently, resulting in a large number of devices and complex processing steps. Secondly, many devices use fixed-angle or simple rotary drum drying, making it impossible to dynamically adjust the position and angle of the heat source based on sand layer thickness, humidity, or material feeding conditions. This easily leads to uneven heating of the sand particles.

[0004] To address the above issues, we have developed a sea sand filter media dryer. Utility Model Content

[0005] This utility model discloses a sea sand filter material dryer, which aims to solve the technical problems in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A sea sand filter media dryer, comprising: The conveying mechanism is configured to be in an inclined state; A drying mechanism is disposed on one side of the conveying mechanism; The conveying mechanism includes a conveyor belt, two rollers are symmetrically arranged inside the conveyor belt, baffles for holding back sea sand are fixedly connected at equal intervals on the surface of the conveyor belt, and grooves for drainage are opened at equal intervals on the conveyor belt.

The filter structure includes a filter frame, and the filter frame is fixedly connected to the drying chamber by a connecting frame.

[0007] In a preferred embodiment, the filter structure further includes a sliding filter plate slidably connected to the filter frame. A filter screen is disposed inside the sliding filter plate. Two damping columns are symmetrically fixedly connected inside the filter frame. The movable ends of the damping columns are connected to the sliding filter plate.

A mounting base is fixedly connected to the outside of the drying chamber, and a drive motor is fixedly connected to the mounting base. Two drive wheels are fixedly connected to the output end of the drive motor, and two cams are symmetrically fixedly connected to the drive roller. Both cams abut against the edge of the sliding filter plate.

[0009] In a preferred embodiment, one end of each of the rollers and the drive roller is fixedly connected to a mating wheel, and two drive wheels are fixedly connected to the output end of the drive motor. A transmission belt is provided between the drive wheel and the corresponding mating wheel.

[0010] In a preferred embodiment, the drying oven is provided with an adjustment structure, the adjustment structure including a slide rod, four fixed blocks are symmetrically fixedly connected to the outside of the drying oven, the slide rod is fixedly connected between two corresponding fixed blocks, and a sliding toothed plate is slidably connected to the outside of each slide rod.

[0011] In a preferred embodiment, two rotating disks are symmetrically rotatably connected to the outer side of the drying oven, and gears are fixedly connected to the outer side of each rotating disk, with each gear meshing with a corresponding sliding toothed plate.

[0014] In a preferred embodiment, a discharge trough is provided on one side of the drying box.

[0015] The sea sand filter media dryer provided by this utility model has the following advantages: This invention uses an inclined conveying mechanism to directly lift wet sand from a lower position and complete the first step of moisture removal. Immediately afterwards, the sea sand automatically falls into the filter structure above the drying mechanism. A drive roller, driven by a drive motor via a drive wheel and transmission belt, drives a cam, causing the sliding filter plate to vibrate continuously under the action of damping columns and springs. This achieves the screening of qualified sand particles. The screened sea sand enters the drying chamber, where an adjustment structure driven by a hydraulic cylinder controls the angular oscillation of the first, second, and third heating plates. This oscillation not only optimizes the hot air contact path and time, significantly improving drying efficiency and uniformity, but the resulting vibration effect also assists in the flow of the sea sand during the drying process and its smooth discharge through the outlet chute. The entire device requires only a single drive motor to simultaneously drive the conveying mechanism and the vibrating screening of the filter structure. It has a compact structure, low energy consumption, and achieves automated and continuous processing from wet sand input to dry sand output. Attached Figure Description

A transmission belt 213 is provided between the drive wheel 210 and the corresponding mating wheel 212. In this embodiment, the drive motor 29 drives the mating wheel 212 connected to the drive roller 211, which in turn drives the drive roller 211 to rotate. At the same time, the drive motor 29 drives the mating wheel 212 connected to the roller 12, which controls the conveying mechanism 1 to perform transportation work.

In this embodiment: the hydraulic cylinder 220 drives the extension rod 219 to move, the extension rod 219 drives the sliding toothed plate 216 to move, thereby achieving the effect of the sliding toothed plate 216 driving the gear 218 to rotate, and the rotation of the gear 218 driving the rotating disk 217 to rotate.

[0033] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in a preferred embodiment, a first heating plate 221, a second heating plate 222, and a third heating plate 223 are rotatably connected inside the drying oven 21. The second heating plate 222 is mirror-symmetrical to the first heating plate 221 and the third heating plate 223. A crossbar is fixedly connected between the two rotating disks 217. The crossbar is rotatably connected to the first heating plate 221. A connecting rope 224 is provided between the first heating plate 221, the second heating plate 222, and the third heating plate 223. In this embodiment: the rotation of the rotating disk 217 causes the crossbar to swing, which in turn causes the first heating plate 221 to rotate. When the first heating plate 221 rotates, the second heating plate 222 and the third heating plate 223 will rotate simultaneously via the connecting rope 224. The purpose of this rotation is to adjust the angle of the heating plates. By adjusting the angle of the heating plates, the contact time between the sea sand and the heating plates can be adjusted, thereby ensuring drying efficiency. At the same time, the vibration effect can be achieved through the forward and reverse swinging, thereby achieving the material feeding effect.

[0034] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in a preferred embodiment, a discharge trough 225 is provided on one side of the drying box 21; In this embodiment, the dried sea sand can be discharged through the discharge chute 225.

[0035] Working principle: First, the sea sand containing moisture is lifted and transported by an inclined conveyor mechanism 1. The surface of the conveyor belt 11 of the conveyor mechanism 1 is equipped with equally spaced baffles 13 to ensure uniform conveying of the sea sand. During the lifting process, the residual moisture inside the sea sand is discharged through the equally spaced grooves 14 on the conveyor belt 11 under the action of gravity and flows to a lower position, achieving preliminary dehydration of the sea sand. The preliminarily dehydrated sea sand is then lifted and falls into the drying mechanism 2 located on one side of the conveyor mechanism 1.

[0036] Sea sand first falls onto the sliding filter plate 24 of the filtration structure. The sliding filter plate 24 has a filter screen 25 embedded inside. Sea sand particles that meet the particle size standard pass through the filter screen 25 and fall down for sieving. Simultaneously, the drive motor 29 starts, and its output drives two drive wheels 210 to rotate. These are connected by a transmission belt 213. The drive wheels 210 drive the mating wheels 212 at the ends of the corresponding rollers 12, causing the conveying mechanism 1 to work continuously. At the same time, the drive wheels 210 also drive the mating wheels 212 at the ends of the drive rollers 211, causing the drive rollers 211 to rotate. Two cams 226 are fixed on the upper part. When the cams 226 rotate, they continuously press against the edge of the sliding filter plate 24, forcing the sliding filter plate 24 to slide on the filter frame 22. When the sliding filter plate 24 moves, it squeezes the movable end of the damping column 26 connected to it and compresses the spring 27 sleeved on the outside of the damping column 26. When the protrusion of the cam 226 rotates, the compressed spring 27 pushes the sliding filter plate 24 to reset. This process is repeated, and the sliding filter plate 24 can generate vibration, which promotes the passage of qualified sea sand through the filter screen 25, prevents the screen holes from clogging, and helps large particles of impurities to move out.

[0037] The qualified sea sand that passes through the filter screen 25 enters the drying chamber 21 for drying. The drying chamber 21 contains a first heating plate 221, a second heating plate 222, and a third heating plate 223. By activating the hydraulic cylinder 220, its output end pushes the extension rod 219 to move. The extension rod 219 drives two sliding toothed plates 216, which are fixedly connected to it, to slide on the slide rod 215. The movement of the sliding toothed plates 216 drives the gear 218 meshing with them to rotate. The gear 218 is fixed on the rotating disk 217, thereby driving the rotating disk 217 to rotate. A crossbar is fixed between the two rotating disks 217, and the crossbar is rotatably connected to the first heating plate 221. The first heating plate 221, the second heating plate 222, and the third heating plate 223 are connected by a connecting rope 224. Therefore, when the rotating disk 217 rotates, the first heating plate 221 is driven to rotate via the crossbar. The first heating plate 221 then synchronously pulls the second heating plate 222 and the third heating plate 223 to swing symmetrically in a mirror image via the connecting rope 224. The advantage of this setting is that adjusting the angle of the heating plates can change the contact time and method between the sea sand and the heat source, thus optimizing the drying efficiency. On the other hand, by making the heating plates swing in both directions to create vibration, the adhering sea sand can be shaken off and promoted to move towards the discharge port. Finally, the dried sea sand is discharged through the discharge chute 225 opened on one side of the drying box 21.
