Description

Technical Field

[0001] This utility model relates to the field of steel ball production, and in particular to a device for treating steel ball grinding debris. Background Technology

[0002] During the steel ball grinding process, the balls are continuously rinsed with water to remove metal debris, grinding shavings, and dust from their surface. The wastewater from this rinsing flows into a wastewater tank for collection. The metal debris and grinding shavings settle in the tank and require regular cleaning. Currently, an electromagnetic adsorption cylinder is used to attract the metal debris and grinding shavings, which are then lifted to a collection box next to the tank. However, because the steel balls themselves accumulate dust throughout the production process, and the wastewater tank is located outside the factory and is an open structure, it contains not only metal debris and grinding shavings but also some sludge. The current method of cleaning with the electromagnetic adsorption cylinder cannot guarantee complete removal, and a thick layer of sludge often remains at the bottom of the tank. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a steel ball grinding sludge treatment device, which can be used in conjunction with gantry crane equipment to clean the sludge in the sewage tank during the steel ball grinding process and improve work efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A steel ball grinding debris sludge treatment device includes a left bucket and a right bucket. Connecting plates are fixed to the outer sides of both buckets. An operating plate is fixed to the upper end of each connecting plate. The two operating plates are cross-shaped and rotatably connected at the intersection. A lifting hole is installed at the upper end of each operating plate, and the lifting hole is connected to a gantry crane via a lifting rope. The lower end of each operating plate extends a certain length beyond the connecting plate. A hook is rotatably installed on the upper part of each operating plate, and a hanging rod is fixed to the lower part of each operating plate. When the two operating plates are folded and retracted, the hook and hanging rod face each other and are hung.

[0005] The hook includes a bent hook portion, and a straight portion is provided at the upper end of the bent hook portion. The straight portion is fixedly connected to the central shaft on the operation panel, and the central shaft is driven to rotate by a motor.

[0006] One of the two control panels is provided with a positioning groove, which is a parallelogram structure.

[0007] The outermost end of the hook portion at the lower end of the hook is horizontal.

[0008] Both the left and right buckets include front and rear first side plates, which are right-angled trapezoidal plates. The upper part between the front and rear first side plates is a second side plate, and the lower part between the front and rear first side plates is a third side plate. The third side plate is arranged at an angle and connected to the inclined sides of the front and rear first side plates.

[0009] The first side plate is fixed with a horizontal reinforcing plate and a vertical reinforcing plate.

[0010] The bucket is made of stainless steel plate.

[0011] This utility model provides a device for treating steel ball grinding debris, which has the following technical advantages: 1) By setting up two sets of hinged operating panels, with the lower ends of the operating panels welded to the buckets, the buckets can be sent into or lifted out of the sewage tank with the assistance of a gantry crane. A rotatable hook is installed on the operating panel; when the hook is engaged with the hanging rod, the left and right buckets can be kept open as needed for dredging. Inside the tank, when it is necessary to close the left and right buckets, the hook can be disengaged from the hanging rod, allowing the left and right buckets to close naturally when the gantry crane lifts the operating panel. Compared to electromagnetic adsorption devices, this device can dredge mud containing non-metallic debris with higher dredging efficiency.

[0012] 2) The structure of the bucket can be strengthened by setting horizontal and vertical reinforcing plates.

[0013] 3) By using a bucket with a pointed bottom, it is easier to insert into the mud layer. Attached Figure Description

Detailed Implementation

[0025] like Figure 1-3 As shown, a steel ball mill slag treatment device is made of stainless steel plate and weighs approximately 50 kg. The buckets include a left bucket 1 and a right bucket 2. Both the left bucket 1 and the right bucket 2 include front and rear first side plates 1.1, which are right-angled trapezoidal plates. A second side plate 1.2 is located above the front and rear first side plates 1.1, and a third side plate 1.3 is located below the front and rear first side plates 1.1. Both the second side plate 1.2 and the third side plate 1.3 are rectangular plates. The third side plate 1.3 is arranged at an angle and connects to the hypotenuse of the two front and rear first side plates 1.1. This arrangement ensures that the tips of the left bucket 1 and the right bucket 2 face downwards, facilitating insertion into the sludge. Connecting plates 3 are vertically welded to the outer sides of the second side plates 1.2 of the left bucket 1 and the right bucket 2. Operating plates 4 are obliquely welded to the two connecting plates 3. The operating plates 4 of the left bucket 1 and the right bucket 2 are arranged front and back and cross each other to form an X-shaped structure. A hole is opened in the center of the intersection of the two operating plates 4 and a pin is installed. In this way, the two operating plates 4 can rotate around the pin, thereby opening or closing the left bucket 1 and the right bucket 2.

[0026] Preferably, such as Figure 5 As shown, one of the two operating plates 4 is provided with a positioning groove 4.1, which is a parallelogram-shaped structure. The inclined surface of the positioning groove 4.1 has a limiting function, preventing the two operating plates 4 from folding further after being closed to a certain extent. Figure 6 As shown, the topmost position is when the two control panels 4 are folded to their limit. At this time, the left bucket 1 and the right bucket 2 are in the open state. The specific open state of the buckets is as follows: Figure 3 As shown. Figure 6 As shown, the bottom diagram illustrates the state after the two control panels 4 are gradually unfolded. Finally, after the two control panels 4 are unfolded, the left bucket 1 and right bucket 2 are in a closed state. The buckets are specifically as follows... Figure 4 As shown.

[0027] Preferably, such as Figure 3As shown, holes are made at the upper edges of the two operating plates 4, and the two ends of the first lifting rope 5 are connected to the two operating plates 4 at the holes. The first lifting rope 5 has a hanging ring 6 in the middle, which can be connected to the second lifting rope 8 of the gantry crane 7.

[0028] Preferably, such as Figure 1 As shown, the upper ends of the two operating plates 4 extend a certain length beyond the connecting plate 3, and the extended parts of the two operating plates 4 are used to rest on the mud collection box 16. The extended length of the two operating plates 4 is about 20cm.

[0029] In addition, rotatable hooks 9 are installed at appropriate positions on the two operating panels 4, and hanging rods 10 are horizontally fixedly extended from the upper end of the corresponding connecting plates 3. When the left bucket 1 and right bucket 2 are open, the hooks 9 and hanging rods 10 are engaged to achieve a limiting position. In this way, when the device is lowered into the sewage tank, it can be ensured that the left bucket 1 and right bucket 2 are always in the open state, ensuring convenient dredging when inserted into the sludge.

[0030] Preferably, the hook 9 includes a bent hook portion, the upper end of which has a straight portion, which is fixedly connected to the central shaft on the operating plate 4. The central shaft is rotatably mounted on the operating plate 4, and a motor is mounted on the back of the operating plate 4, with the motor's output shaft connected to the central shaft. The motor is a miniature waterproof motor, model: Portescap Athlonix 08G (8mm BLDC).

[0031] Preferably, in order to reasonably control the rotation angle of the hook 9, a magnetic encoder (AS5600) is installed at the tail of the motor or the end of the central shaft of the hook.

[0032] The control box of the gantry crane 7 contains a motor driver (TB6612FNG) and a microcontroller (STM32F103C8T6), which are connected to the power supply of the gantry crane 7.

[0033] like Figure 7 As shown, the outermost end of the hook portion at the lower end of the hook 9 has a straight section. This straight section is horizontal when the hook hangs naturally. When the two operating plates 4 are folded to their limit positions, the hook portion of the hook 9 is directly opposite the hanging rod 10, and the hook 9 naturally becomes vertical under gravity, with the hook portion at the lower end of the hook 9 naturally hooked onto the hanging rod 10. When pulled by the traction rope 12, the hook portion at the lower end of the hook 9 can detach from the hanging rod 10.

[0034] In addition, to prevent the hook 9 from accidentally coming off, magnets are embedded in the hook part of the hook 9 and the side wall of the hanging rod 10, so that the hook 9 and the hanging rod 10 can be magnetically attracted and fixed when they are in the hanging state.

[0035] like Figure 2As shown, preferably, horizontal reinforcing plates 14 are fixed to the outer sides of the first side plates 1.1 of both the left bucket 1 and the right bucket 2. The horizontal reinforcing plate 14 of the left bucket 1 extends laterally and can contact the first side plate 1.1 of the right bucket 2, and the horizontal reinforcing plate 14 of the right bucket 2 extends laterally and can contact the first side plate 1.1 of the left bucket 1. The horizontal reinforcing plates 14 of the left bucket 1 and the right bucket 2 are spaced apart vertically.

[0036] like Figure 2 As shown, preferably, a longitudinal reinforcing plate 15 is fixed on the first side plate 1.1 (front side plate) of the left bucket 1, and a longitudinal reinforcing plate 15 is fixed on the first side plate 1.1 (rear side plate) of the right bucket 2. Both longitudinal reinforcing plates 15 are vertically located at the closing joint of the left bucket 1 and the right bucket 2 and partially protrude. The horizontal reinforcing plate 14 and the longitudinal reinforcing plate 15 not only serve to strengthen the structure, but also play a positioning role during the closing process of the left bucket 1 and the right bucket 2, ensuring that they are aligned and without deviation after closing.

[0037] During dredging, the wastewater from the steel ball grinding process is discharged from the sludge pond and does not affect normal production.

[0038] The surface of the bucket in this application is sandblasted and then coated with an epoxy anti-corrosion coating, which provides corrosion resistance.

[0039] Working principle and process: 1) Before operation, the device is placed on the sludge collection box 16 next to the sewage tank. At this time, the left bucket 1 and the right bucket 2 are in the open state, and the hook 9 is attached to the hanging rod 10; the traction rope 12 is in the slack state.

[0040] 2) For example Figure 8 As shown, during excavation, firstly, the winch on the gantry crane 7 (small gantry crane) lifts the buckets to a certain height, away from the ground; the gantry crane 7 moves the left bucket 1 and right bucket 2 directly above the surface of the sewage tank; then, the winch on the gantry crane 7 releases the second hoisting rope 8, causing the left bucket 1 and right bucket 2 to descend into the sewage tank at a certain speed; after reaching the silt layer of the sewage tank, under the action of gravity and at a certain speed, the left bucket 1 and right bucket 2 insert into the silt.

[0041] 3) Then the motor drives the hook 9 to rotate at a certain angle and then stops. The hook 9 is disengaged from the hanging rod 10, so that the two operating plates 4 are freed from the restriction and can be unfolded freely.

[0042] 4) Then the winch of the gantry crane 7 drives the two operating plates 4 to lift, and the two operating plates 4 unfold. At this time, the left bucket 1 and the right bucket 2 close, thereby clamping the sludge.

[0043] 5) As the gantry crane 7 continues to lift, the left bucket 1 and the right bucket 2 gradually leave the water surface.

[0044] 6) For example Figure 9 As shown, after the bucket is lifted a certain height above the water surface, the small gantry crane 7 moves the bucket horizontally to the top of the sludge collection box next to the pool. The small gantry crane 7 then moves the bucket downwards. The lower parts of the two operating plates 4 gradually rest on the upper surface of the sludge collection box 16. The two operating plates 4 rotate around the pin and fold together, so that the left bucket 1 and the right bucket 2 gradually open. At the same time, after the two operating plates 4 are folded to their limit positions, the motor drives the hook 9 to rotate in the opposite direction at a certain angle and then stops, so that the hook 9 and the hanging rod 10 are hooked together again.
