AI Technical Summary
During the conveying process of water-washed sand, the design of the hopper discharge port makes it difficult to effectively reduce the moisture content of the water-washed sand, and the deflector will hinder the normal operation of the discharge port during unloading.
Design a hopper automatic water contact device under pits, including a hopper, a conveyor belt and a water guide tank. The end of the water guide tank extends to the outside of the conveyor belt. When the valve baffle is closed, the water guide tank receives and guides water from the hopper discharge port to prevent water from flowing onto the conveyor belt. When the valve baffle is opened, the water guide groove moves and avoids the discharge path to ensure normal discharge.
Through this device, the moisture content of the washed sand is effectively reduced, reaching the moisture content below 6% required by the customer, and the automatic water diversion and discharge of water is realized without affecting the discharge of the washed sand.

Technical Field
[0001] The utility model relates to the technical field of water removal from washed sand, in particular to an automatic water receiving device for a pit feeding hopper. Background Technique
[0002] It is not conducive to transportation if the water content of washed sand is too high. Therefore, the lower the water content of washed sand is controlled, the better. At present, some customers require the water content of washed sand to be reduced from 12% to 8% before shipping, and even some customers require it to be below 6%.
[0003] To save costs, the washed sand in the stockyard is usually piled on the ground, and the conveyor belt and the hopper are arranged in a pit for transportation. During the process of discharging the hopper to the conveyor belt, dehydration treatment can be carried out. When the discharge port of the hopper is closed, the water in the washed sand will seep downward and flow out through the gap between the discharge port and the valve. Since the discharge port faces the position of the conveyor belt, the seeped water will directly fall into the washed sand on the conveyor belt. Therefore, the purpose of overall dehydration has not been achieved yet. Installing a diversion plate below the discharge port to divert the seeped water to the outside of the conveyor belt can discharge the seeped water to the outside, thus playing a role in dehydration. However, when the valve at the discharge port is opened for discharging, the diversion plate will prevent the normal discharging of the discharge port.
[0004] Therefore, an automatic water receiving device for a pit feeding hopper is needed to solve the above technical problems. Content of the Utility Model

[0023] The principles and features of the present utility model will be described below in conjunction with the drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.
[0024] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , a pit hopper automatic water receiving device includes a hopper 1 and a conveyor belt 6. A hopper discharge port 3 is provided on the side of the hopper 1, and the hopper discharge port 3 is used to discharge the washed sand in the hopper. A valve baffle 2 is installed at the hopper discharge port 3. When the valve baffle 2 is in the closed state, the water in the washed sand in the hopper 1 will seep out from the gap at the bottom of the valve baffle 2. When the valve baffle 2 is in the open state, the washed sand in the hopper 1 is discharged from the hopper discharge port 3. A water guide groove 4 is provided at the bottom of the hopper discharge port 3, and the water guide groove 4 is used to receive and divert the water seeping out from the washed sand to the outside of the conveyor belt 6. The hopper discharge port 3 and the water guide groove 4 are both located above the conveyor belt 6, and the end of the water guide groove 4 extends to the outside of the conveyor belt 6. The conveyor belt 6 is installed on the upper side of the conveyor belt support 5. Multiple hoppers 1 can be provided on the conveyor belt 6, and the valve baffle 2 on each hopper 1 is independently controlled.
[0025] Embodiment 1: A rotating shaft 10 penetrates through the inside of the hopper discharge port 3. Both sides of the valve baffle 2 are fixedly connected to the rotating shaft 10, and the rotating shaft 10 is rotatably connected to the hopper discharge port 3. A telescopic driving member 7 is installed at the bottom of the hopper discharge port 3, and the telescopic driving member 7 is a hydraulic push rod. A push rod 11 is fixed to the telescopic end of the telescopic driving member 7. The cross-section of the water guide groove 4 is V-shaped, the end of the water guide groove 4 is inclined downward, and the water guide groove 4 is perpendicular to the conveying direction of the conveyor belt 6. A rotating plate 15 is fixed to the water guide groove 4, and the rotating plate 15 is hinged to the lower side of the hopper discharge port 3. The push rod 11 is connected to the rotating plate 15. Specifically, a rectangular groove 16 is provided on the rotating plate 15, and a guiding slider 19 is provided at the end of the push rod 11. The guiding slider 19 is located in the rectangular groove 16, and the guiding slider 19 is slidably connected to the rectangular groove 16. When the telescopic driving member 7 operates, it pushes the push rod 11 to move. The guiding slider 19 slides in the rectangular groove 16 and pushes the rotating plate 15 to rotate around the hinge point, and at the same time the water guide groove 4 rotates accordingly.
[0026] A transmission assembly is provided between the push rod 11 and the rotating shaft 10. The transmission assembly includes a first gear 18, a second gear 8, a third gear 9, and a rack 17. The rack 17 is fixedly connected to the push rod 11, the rack 17 meshes with the first gear 18, the first gear 18 meshes with the second gear 8, the second gear 8 meshes with the third gear 9, and the third gear 9 is fixedly sleeved outside the rotating shaft 10. A guiding plate 12 is fixed to the bottom of the push rod 11, a guiding rod 13 is fixed to the guiding plate 12, and a guiding sleeve 14 is fixed to the bottom of the telescopic driving member 7. The guiding rod 13 is slidably inserted into the guiding sleeve 14.
[0027] When the push rod 11 moves forward, it drives the rack 17 to move forward, thereby driving the first gear 18 to rotate counterclockwise, the second gear 8 to rotate clockwise, the third gear 9 to rotate counterclockwise, and further driving the rotating shaft 10 to rotate counterclockwise. The rotating shaft 10 drives the valve baffle 2 to rotate counterclockwise, thereby opening the hopper discharge port 3. At this time, the push rod 11 pushes the top of the rotating plate 15 forward through the guiding slider 19, so that the water guide groove 4 rotates clockwise, making the water guide groove 4 vertically hang down, thereby avoiding blocking the discharge of the washed sand and avoiding affecting the unloading. The washed sand is discharged onto the conveyor belt 6. On the contrary, when the push rod 11 moves backward, the valve baffle 2 rotates clockwise to close the hopper discharge port 3, and the water guide groove 4 rotates counterclockwise, so that the water guide groove 4 is located at the lower end position of the valve baffle 2. The water in the washed sand seeps out along the gap at the lower end of the valve baffle 2 and flows into the water guide groove 4, and the water is diverted to the outside of the conveyor belt through the water guide groove 4. Thus, part of the water can be discharged when unloading is not carried out.
[0028] Embodiment 2: The water guide groove 4 is fixed to the lower end of the valve baffle 2. The upper end of the valve baffle 2 is hinged to the upper end of the hopper discharge port 3. The valve baffle 2 can rotate at the port plane of the hopper discharge port 3. The valve baffle 2 is driven by a cylinder or a hydraulic push rod to open and close the valve baffle 2. At this time, the valve baffle 2 is planar, rather than the U-shaped shape in Embodiment 1. When the valve baffle 2 is closed, the water guide groove 4 is located at its bottom for guiding the seepage water out of the conveyor belt. When the valve baffle 2 is opened, the water guide groove 4 rotates with it to the side of the hopper discharge port 3, thus not affecting the discharging.
