Description

Technical Field

[0001] The invention relates to calcium carbonate production equipment, in particular to a two-way in-and-out lifting and conveying mechanism for a calcium carbonate production line. Background Art

[0002] Due to the complex production process of calcium carbonate and the large number of production equipment required, which occupies a large space, manufacturers generally divide the entire calcium carbonate production line into multiple areas and arrange them on different floors, thereby reducing land occupation and facilitating the management of different areas. In order to facilitate the transportation and transfer of raw materials, semi-finished products and other materials between floors, corresponding lifting and conveying equipment is required to realize the cross-floor transportation of materials.

[0003] At present, the lifting and conveying equipment commonly used in calcium carbonate production lines mainly consists of Z-type elevators and freight elevators. Among them, Z-type elevators are mostly used to transport raw materials, semi-finished products or finished products. Its advantages are high transportation efficiency, good stability and strong sealing. The disadvantage is that the inlet and outlet positions of the elevator are relatively fixed, and the number of inlet and outlet cannot be adjusted or increased or decreased manually, making it difficult to transport materials to multiple floors. Freight elevators are mostly used to transport waste materials such as garbage and sludge. Its advantages are that it can realize feeding and unloading at any floor, so that waste materials in different production areas can be sent to the designated floor for processing through freight elevators. The disadvantage is that freight elevators only have lifting functions. In actual transportation, they need to be used in conjunction with carriers such as manual carts or electric material carts. That is, during the feeding process, the waste needs to be dumped from the production line to the carrier, and then the carrier enters the freight elevator by manual pushing or rail transportation; after the freight elevator reaches the designated floor, it is transported out of the freight elevator by the carrier and poured into the subsequent processing equipment by a special dumping mechanism, thereby increasing the complexity of the entire transportation process and equipment cost.

[0004] On the other hand, the current carriers are all in the shape of rectangular boxes, which means that they need to be rotated to more than 90 degrees when dumping to ensure that the waste in the carrier is completely dumped without leaving any residue. Even if an inverted trapezoidal structure is used, the rotation angle must reach more than 60°, and the capacity of the box will decrease accordingly. This results in the dumping mechanism needing to have a large rotation stroke and corresponding clamps to prevent the carrier from falling during the flipping process, which increases the equipment cost and structural complexity of the dumping mechanism.

[0005] Therefore, the lifting and conveying equipment used for waste material conveying in the existing calcium carbonate production line has the problems of low conveying efficiency and high conveying cost. Summary of the invention

[0006] The purpose of the present invention is to provide a two-way in-and-out lifting and conveying mechanism for a calcium carbonate production line, which has the characteristics of high conveying efficiency and low conveying cost.

[0007] The technical solution of the present invention is as follows: a two-way in-and-out lifting and conveying mechanism for a calcium carbonate production line comprises a frame, the inner side of the frame is connected to a lifting frame via a lifting and conveying rope group, both sides of the lifting frame are respectively connected to a symmetrical left lifting rod and a right lifting rod, the lower ends of the left lifting rod and the right lifting rod are connected to the lifting frame, the upper ends of the left lifting rod and the right lifting rod are rollingly connected to a conveying box via supporting wheels, both sides of the conveying box are provided with dumping ports, the outside of the dumping port is provided with a baffle rotatably connected to the conveying box, the middle parts of the two ends of the baffle are connected to tightening pieces, the tops of the two ends of the baffle extend to the outside of the conveying box and are provided with a transmission pin, the end of the transmission pin extends to the outside of the lifting frame, the lifting frame is provided with a guide port that matches the transmission pin, the outer wall of the lifting frame is rotatably connected to a first gas spring, the rod head of the first gas spring is connected to a clamping block located in the guide port, and the clamping block is provided with a push-pull groove that matches the transmission pin.

[0008] In the aforementioned bidirectional in-and-out lifting and conveying mechanism for a calcium carbonate production line, the conveying box is provided with a mountain rail connected to a supporting wheel, and limit blocks are provided at both ends of the mountain rail.

[0009] In the aforementioned bidirectional in-and-out lifting and conveying mechanism for a calcium carbonate production line, the lifting and transporting rope group includes a steel wire rope and lifting wheels, the lifting wheels are symmetrically arranged on both sides of the lifting frame, one end of the steel wire rope is wound around the lifting wheel, and the other end of the steel wire rope extends to the top of the frame and is connected to a wire reel, and one end of the wire reel is connected to a driving motor via a universal coupling.

[0010] In the aforementioned bidirectional in-and-out lifting and conveying mechanism for a calcium carbonate production line, the push-pull groove is semicircular in shape and the groove direction faces the transmission pin.

[0011] In the aforementioned bidirectional in-and-out lifting and conveying mechanism for a calcium carbonate production line, a plurality of inlets or outlets are respectively provided on both sides of the frame in the height direction, the outside of the inlet is connected to a feeding mechanism, and the outside of the outlet is connected to a discharging mechanism.

[0012] In the aforementioned bidirectional in-and-out lifting and conveying mechanism for a calcium carbonate production line, a plurality of lower proximity switches cooperating with the inlet and upper proximity switches cooperating with the outlet are respectively provided on both sides of the frame along the height direction.

[0013] In the aforementioned bidirectional in-and-out lifting and conveying mechanism for a calcium carbonate production line, the tightening member is a second gas spring, and the end of the second gas spring is connected to the outer wall of the conveying box.

[0014] In the aforementioned bidirectional in-and-out lifting and conveying mechanism for a calcium carbonate production line, the maximum inclination angle of the conveying box on the lifting frame is 15 to 30 degrees.

[0015] Compared with the prior art, the present invention has the following characteristics:

[0016] (1) The present invention can realize the cross-floor transportation of the conveying box through the cooperation of the lifting frame and the lifting and transporting rope group, and the conveying box can be rotated to a specified angle when discharging materials through the cooperation of the left lifting rod, the right lifting rod and the conveying box. Under the above cooperation, the lifting and loading and unloading of waste materials can be completed in the lifting and conveying mechanism of the present invention. Compared with the conventional cargo elevator, the corresponding carrier and dumping mechanism are omitted, thereby improving the transportation efficiency of waste materials and reducing its equipment cost;

[0017] (2) Through the structural coordination of the left lifting rod, the right lifting rod and the supporting wheel, the conveying box can be tilted to a specified angle during discharge, so that the waste can move toward the dumping port at this angle; when the conveying box is tilted to the middle position, the transmission pin will move with the tilt to engage with the locking block, and under the subsequent tilting action, the push-pull groove applies a pulling force outside the tilt to the first gas spring, so that the first gas spring pops out under the action of the pulling force and drives the baffle to rotate and open, thereby causing the second gas spring to pop out, so that the waste in the conveying box can be directly discharged from the dumping port. Compared with the existing dumping method, it can effectively reduce the required tilt angle of the conveying box, which is convenient for the discharge of waste; at the same time, the baffle can also play a guiding function after opening, so that the waste can be transported along the baffle to the outside of the frame and fall into the discharge mechanism, thereby improving the transportation stability of the waste;

[0018] (3) When the discharge is completed, the conveyor box is reset to a horizontal position and the transmission pin applies an inward thrust to the first gas spring during the rotation process, so that the first gas spring contracts and resets and drives the baffle to re-fit the pouring port, causing the second gas spring to contract; after contraction, the second gas spring can apply a stable pre-tightening force to the baffle, so that the baffle fits tightly against the pouring port to achieve sealing; and under the above cooperation, the baffle can automatically open to discharge the material after the conveyor box is tilted to a specified angle, and automatically contract when the conveyor box is reset, thereby effectively improving its discharge and discharge stability, and this action can be completed with the flipping of the conveyor box, without the need for a corresponding electric drive component, thereby simplifying the control difficulty of the conveyor box and further reducing its equipment cost;

[0019] (4) By defining the shape of the push-pull groove, the transmission pin at one end of the conveying box can slide into and engage the push-pull groove during the rotation process, while the transmission pin at the other end does not contact the locking block as the conveying box rises, thereby achieving stable use of the structure under the two-way entry and exit structure;

[0020] Therefore, the present invention has the characteristics of high conveying efficiency and low conveying cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

The end of the transmission pin 10 extends to the outside of the lifting frame 2, and the lifting frame 2 is provided with a guide port 11 that matches the transmission pin 10. The outer wall of the lifting frame 2 is rotatably connected to a first gas spring 12, and one side of the first gas spring 12 is limited by an angle of a limiting plate. The rod head of the first gas spring 12 is connected to a clamping block 13 located in the guide port 11, and the clamping block 13 is provided with a push-pull groove 14 that matches the transmission pin 10, and the notch of the push-pull groove 14 is equal to the outer diameter of the transmission pin 10.

[0029] The conveying box 6 is provided with a mountain rail 15 connected to the supporting wheel 5 , and limit blocks 16 are provided at both ends of the mountain rail 15 .

[0030] The lifting and transporting rope group includes a steel wire rope 17 and a lifting wheel 18. The lifting wheels 18 are symmetrically arranged on both sides of the lifting frame 2. One end of the steel wire rope 17 is wound around the lifting wheel 18. The other end of the steel wire rope 17 extends to the top of the frame 1 and is connected to a take-up drum 19. One end of the take-up drum 19 is connected to a drive motor 20 via a universal coupling 21. The lifting frames 2 on both sides of the steel wire rope 17 can be slidably connected to the frame 1 via guide rails 22.

[0031] The push-pull groove 14 is semicircular in shape and its opening direction faces the driving pin 10 .

[0032] A plurality of inlets 23 or outlets 24 are respectively provided on both sides of the frame 1 along the height direction, and the floor position and orientation of the inlets 23 or outlets 24 can be adjusted as needed. The outside of the inlets 23 is connected to a feeding mechanism, and the outside of the outlets 24 is connected to a discharging mechanism; the feeding mechanism and the discharging mechanism can select conventional conveying equipment such as a screw conveyor and a conveyor belt, and the conveying box 6 and the feeding mechanism and the discharging mechanism are staggered left and right.

[0033] Both sides of the frame 1 are provided with a plurality of lower proximity switches cooperating with the inlet 23 and upper proximity switches cooperating with the outlet 24 along the height direction. The upper proximity switches and the lower proximity switches are respectively used to control the height position of the lifting frame 2 during feeding and discharging. When the lifting frame 2 is feeding, the conveying box 6 is lower than the discharge port of the feeding mechanism, and when the lifting frame 2 is discharging, the conveying box 6 is higher than the upper end surface of the discharging mechanism.

[0034] The tightening member 9 is a second gas spring, and an end of the second gas spring is connected to the outer wall of the conveying box 6 .

[0035] The maximum inclination angle of the conveying box 6 on the lifting frame 2 is 15 to 30 degrees.

[0036] Working principle of the present invention: When designing and installing the present invention, the manufacturer can set the inlet 23 and outlet 24 of the same or different heights on both sides of the frame 1 according to needs, and the directions of the inlet 23 and outlet 24 can also be adjusted left and right, so that the lifting and conveying mechanism can realize the feeding and unloading of materials at different positions of any floor. When in use, the drive motor 20 drives the wire reels 19 on both sides to rotate through the universal coupling 21 to reel in or unreel, thereby cooperating with the lifting wheel 18 to drive the lifting frame 2 to lift and lower, thereby realizing the cross-floor transportation of the conveying box 6; when the conveying box 6 reaches the feeding position, the conveying box 6 can be kept in a horizontal state or rotated to an inclined state as needed, so that the feeding mechanism can extend into the upper inner side of the conveying box 6 and deliver the waste into the conveying box 6.

[0037] When the conveying box 6 needs to be rotated to the inclined feeding state, the left lifting rod 3 drives one end of the conveying box 6 to push upward, and the right lifting rod 4 is in a retracted state, so that the conveying box 6 is tilted toward the inlet 23 and extends to the bottom of the discharge port of the feeding mechanism under the above-mentioned action, so that the waste can fall into the conveying box 6 through the feeding mechanism; the actions of the left lifting rod 3 and the right lifting rod 4 during feeding and discharging can be changed and adjusted according to the positions of the inlet 23 and the outlet 24. During feeding, the inclination angle of the conveying box 6 is less than its maximum inclination angle, so that the transmission pin 10 is in a mutually separated state with the clamping block 13 after rotation, thereby ensuring the closed state of the baffle 8. After the dropping is completed, the left lifting rod 3 is reset to make the conveying box 6 return to the horizontal position, and then the lifting rope group drives the lifting frame 2 to the next feeding position or discharging position. The photoelectric sensor in the conveying box 6 can detect the waste filling amount in the conveying box 6. If the conveying box 6 is fully loaded, it will directly move to the discharging position for discharging.

[0038] When the conveying box 6 reaches the discharge position, the right lifting rod 4 drives one end of the conveying box 6 to push upward, and the right lifting rod 4 is in a retracted state, so that the conveying box 6 is tilted toward the outlet 24 and extends to the top of the discharge mechanism under the above action. When the conveying box 6 is tilted to a maximum inclination angle, the transmission pin 10 moves to the inner end of the guide port 11 with the rotation and interlocks with the push-pull groove 14. When the transmission pin 10 contacts the push-pull groove 14, the tilting action of the conveying box 6 will drive the transmission pin 10 to push the engaging block 13 toward the outlet 24, so that the first gas spring 12 will directly extend outward under the pushing action and drive the baffle 8 to rotate and open. After the baffle 8 is opened, the tightening member 9 is opened accordingly, so that the baffle 8 is in a blanking state, and the conveying box 6 reaches the maximum inclination angle, so that the waste in the conveying box 6 can fall downward from the pouring port 7 and enter the discharge mechanism. Since the dumping port 7 is located at the lower side wall of the conveying box 6, the conveying box 6 only needs to maintain a tilt state of 15 to 30 degrees to ensure complete discharge of the waste, thereby reducing the difficulty of conveying the waste. At the same time, the transmission pin 10 on the other side is away from the guide port 11 during the discharge process, that is, it is separated from the clamping block 13, so that the tightening member 9 on the other side can maintain a contracted state, thereby ensuring the stability of the movement of the conveying box 6.

[0039] After the material is dropped, the right lifting rod 4 is reset to drive the conveying box 6 to rotate to a horizontal position; when the conveying box 6 starts to reset, the transmission pin 10 applies an inward extrusion force to the first gas spring 12 as it rotates, thereby driving the first gas spring 12 to contract and driving the baffle 8 to rotate to a closed state. After the baffle 8 rotates, it drives the tightening member 9 to contract, so that the tightening member 9 can pre-tighten the baffle 8 after contraction, ensuring the sealing effect between the baffle 8 and the conveying box 6. When the baffle 8 is contracted to the right position, the transmission pin 10 is disengaged from the push-pull groove 14 as it rotates, and continues to move along the upper end surface of the guide port 11 until it is separated from the lifting frame 2, realizing the reset function.

[0040] When designing the actions of the right lifting rod 4 and the left lifting rod 3, the linkage action of the conveying box 6 after approaching the maximum inclination angle and before the rotation and reset can be adjusted based on the telescopic action of the first gas spring 12. When the transmission pin 10 is buckled into the push-pull groove 14, the transmission pin 10 can be driven to move downward to the outside to apply a stable pulling force to the first gas spring 12, thereby ensuring the ejection of the first gas spring 12. Similarly, when the conveying box 6 is reset, the right lifting rod 4 and the left lifting rod 3 can be driven to move upward to the inside to apply a stable pressure to the first gas spring 12 through linkage, thereby ensuring the contraction of the first gas spring 12.
