Description

Technical Field

[0001] This utility model relates to the field of sand making equipment technology, and in particular to an integrated dry sand making equipment. Background Technology

[0002] With the development of the construction industry, the demand for manufactured sand as a substitute has increased dramatically, prompting the industry to explore efficient sand making technology. Dry sand making has become the preferred choice due to its advantages such as water saving and no climate restrictions. The existing integrated dry sand making equipment can basically meet the daily use needs, but there are still some shortcomings that need to be improved.

[0003] Existing integrated dry sand making equipment often uses open or simple sealed structures for the finished fine sand discharge port. During the process of transporting fine sand from the discharge port to the storage tank, dust is easily generated due to material flow and air disturbance, which not only causes fine sand loss but also easily leads to the deterioration of the working environment. To address this, we propose an integrated dry sand making equipment that uses a sealed unloading structure outside the finished fine sand discharge port to ensure that no dust overflows during the process of fine sand flowing from the discharge port to the storage tank. This solves the problem of dust generation at the discharge port of traditional production lines. Utility Model Content

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] This utility model provides a technical solution: such as Figures 1 to 6 As shown in this embodiment, an integrated dry sand making device includes a circulating elevator control platform 1, a vertical impact sand making machine 2, a triaxial elliptical screen 3, a gradation adjuster 4, a return conveyor belt 5, a belt weighing scale 6, a fine sand elevator 7, a classifier 8, a finished fine sand outlet 9, and a storage tank 10. A sealed discharge structure is provided at the lower end of the finished fine sand outlet 9, which is connected to the storage tank 10 via the sealed discharge structure. The sealed discharge structure includes a rotating sleeve 11 rotatably connected to the bottom end of the finished fine sand outlet 9. Sleeves 12 are installed at both ends of the rotating sleeve 11, and a fixed structure is located above the rotating sleeve 11. The top of the storage tank 10 is connected to the sleeve plate 13 via the tank opening 14, and an extension edge 15 is installed on both sides of the top of the extension edge 15. An extension rod 17 is provided in each of the two sets of locking rods 16. Locking holes 21 are opened on both sides of the sleeve plate 13. The two sets of extension rods 17 pass through the two sets of locking holes 21. Two sets of arc-shaped locking plates 20 are provided between the rotating sleeve 11 and the sleeve plate 13. The middle of the two sets of locking rods 16 is provided with a slot 19 that cooperates with the arc-shaped locking plate 20. The two sets of arc-shaped locking plates 20 are embedded in the two sets of slots 19. Pull rings 18 are fixed to the upper external parts of the two sets of extension rods 17. Elastic components are provided in the two sets of sleeve plates 13.

[0018] By installing a rotatable sleeve 11 and two sets of arc-shaped clamping plates 20 on the lower exterior of the finished fine sand outlet 9, the storage tank 10 can drive two sets of locking rods 16 through two sets of sleeves 12, and rotate the two sets of storage tanks 10 and the sleeve 11, so that the two sets of locking rods 16 rotate into the two sets of arc-shaped clamping plates 20, and the two sets of arc-shaped clamping plates 20 fit outside the two sets of clamping grooves 19. This facilitates a quick and easy sealing connection between the finished fine sand outlet 9 and the storage tank 10, and locks the position of the storage tank 10. Furthermore, the elastic component can push the two sets of extension rods 17 into the two sets of locking holes 21, further forming a connection between the finished fine sand outlet 9 and the storage tank 10. This effectively prevents dust from spilling out of the fine sand during transportation due to air disturbance or material flow. When it is necessary to disassemble the storage tank 10, the two sets of extension rods 17 can be pushed out of the two sets of locking holes 21, which facilitates the quick disassembly of the storage tank 10 and improves the convenience of using the device.

[0019] In other embodiments, the elastic component includes a movable inner cavity 23 formed in the sleeve 13, guide sliders 24 are installed on the outside of the extension rods 17, and return springs 25 are wound around the lower end of the extension rods 17. By installing a return spring 25 inside the locking rod 16 and a guide slider 24 at the lower end of the extension rod 17, the return spring 25 can apply an upward elastic force to the guide slider 24, allowing the extension rod 17 to be embedded in the two sets of guide grooves 22. The two sets of extension rods 17 can then move along the guide grooves 22 to the locking holes 21, thus quickly embedding the two sets of extension rods 17 into the two sets of locking holes 21. This quickly forms a rotation limit on the two sets of extension rods 17, further improving the stability of the equipment during use.

[0020] In other embodiments, multiple sets of sealing rings are installed on the inner wall of the connecting can opening 14; With this design, the sealing ring is installed on the inner wall of the connecting tank opening 14. When the finished fine sand outlet 9 is connected to the storage tank 10, the sealing ring is compressed, which can form multiple sealing barriers to prevent dust from overflowing from the connection gap. The multiple sets of sealing rings enhance the sealing performance of the connection and further eliminate dust leakage.

[0021] In other embodiments, the sealed unloading structure also includes two sets of guide grooves 22 opened at the bottom end of the sleeve plate 13, the ends of the guide grooves 22 are connected to the lock hole 21, and the inner wall of the guide grooves 22 is polished. With this design, when the two sets of sleeves 13 drive the two sets of extension rods 17 through the two sets of sleeves 12, so that the tops of the two sets of extension rods 17 are embedded in the two sets of guide grooves 22, the storage tank 10 can then be rotated, so that the two sets of sleeves 13 drive the rotating sleeve 11 to rotate. The polished inner wall of the guide groove 22 reduces frictional resistance, allowing the two sets of extension rods 17 to slide smoothly in the two sets of guide grooves 22, ensuring that the locking process is fast and accurate.

[0022] In other embodiments, the outer wall of the pull ring 18 is all polished; This design effectively increases the friction between the pull ring 18 and the user's hand, making it easier to push the pull ring 18 effectively.

[0023] In other embodiments, the outer side of the guide slider 24 is fully fitted with the inner wall of the movable inner cavity 23, and the guide slider 24 and the movable inner cavity 23 are slidably connected. With this design, when the guide slider 24 can move laterally along the inside of the movable inner cavity 23, it can effectively avoid large shaking of the guide slider 24 during the movement, thereby improving the stability of the guide slider 24 when it moves.

[0024] In other embodiments, the two ends of the return spring 25 are respectively connected to the outer wall of the guide slider 24 and the inner wall of the movable inner cavity 23, and the guide slider 24 forms an elastic connection with the inner wall of the movable inner cavity 23 through the guide slider 24; This design allows the return spring 25 to apply an upward elastic force to the guide slider 24, which in turn allows the guide slider 24 to drive the extension rod 17 upward, enabling the extension rod 17 to be quickly inserted into the two sets of locking holes 21 on the sleeve plate 13.

[0025] This utility model provides an integrated dry sand making device, the specific working principle of which is as follows: Raw material processing and sand making: The raw material is fed into the vertical impact sand making machine 2 through the circulating elevator control platform 1 for crushing and sand making.

[0026] Screening and gradation adjustment: The material after sand making is screened by a three-axis elliptical screen 3. Qualified fine sand enters the gradation adjustment machine 4 for particle size optimization, and unqualified material is returned to the sand making machine for reprocessing via the return conveyor belt 5.

[0027] Metering and Lifting: Belt weigher 6 controls the quantity of materials, and fine sand elevator 7 lifts the fine sand to classifier 8.

[0028] Powder selection and discharge: The powder classifier 8 separates the finished fine sand and outputs it through the finished fine sand discharge port 9.

[0029] Sealed unloading and storage: The finished fine sand enters the storage tank 10 through the sealed unloading structure. The sealed unloading structure, through the coordinated action of the rotating sleeve 11, the sleeve plate 13, the locking rod 16 and the elastic components, ensures a fully sealed connection between the finished fine sand outlet 9 and the storage tank 10, allowing the fine sand to flow under gravity. However, due to the sealed structure, the dust is completely sealed off, and there is no risk of spillage.
