Technical Field

[0001] The utility model relates to the technical field of gypsum transfer equipment, in particular to a rotary lifting platform for gypsum transfer. Background Art

[0002] A large amount of flue gas is generated during thermal power generation. This workshop uses limestone slurry to replace harmful sulfur dioxide in the flue gas, and then the limestone slurry containing sulfur dioxide undergoes a series of dehydration treatments to form gypsum solids.

[0003] The existing gypsum produced all falls into the gypsum warehouse through belts, and then enters the gypsum warehouse for transportation of gypsum by forklifts. Since the production of gypsum is not continuous, when the production interval between the new gypsum and the old gypsum is long, the new gypsum will cover the old gypsum, causing some gypsum to accumulate for too long, thus affecting the manufacturer's use effect.

[0019] The first motor 6 can drive the worm 5 to rotate, and through the cooperation between the worm 5 and the worm wheel 4, drive the rotating shaft 3 to rotate, and then drive the turntable 2 to rotate through the rotating shaft 3, so that the turntable 2 can rotate.

[0020] The second motor 9 controls the rotation of the screw rod 8 and the threaded connection between the screw rod 8 and the moving block 10, so as to control the moving block 10 to make up and down linear motion in the mounting groove 7, so that the moving block 10 can drive the load-bearing platform 11 to move up and down along the turntable 2. A support rod 29 is also provided between the load-bearing platform 11 and the moving block 10 to improve the load-bearing capacity of the load-bearing platform 11.

[0021] The produced gypsum is transported to the receiving part through the conveying device 28. When the receiving part needs to receive gypsum, it needs to be pushed onto the weighing device 12. The weighing device 12 is used to detect the weight of the gypsum received in the receiving part. Then the receiving part is moved to the position below the discharge port of the conveying device 28, and then the gypsum is continuously transported to the receiving part. When the mass of the gypsum in the receiving part reaches a certain mass, the conveying device 28 needs to temporarily stop moving, and then the turntable 2 is controlled to rotate to move the empty receiving part on the other weighing device 12 to the discharge port of the conveying device 28. Below, the conveying equipment 28 is then started to continue to transport gypsum into the empty receiving part, and the receiving part located on the weighing device 12 and already loaded with gypsum, controls the load-bearing platform 11, the weighing device 12 and the receiving part on the weighing device 12 to move downward through the corresponding second motor 9, and transfers the receiving part on the weighing device 12 away from the weighing device 12, which can be done manually or by an electric hoist in the factory. After the receiving part is transferred out, the new receiving part can be pushed back onto the weighing device 12 to facilitate the subsequent receipt of gypsum.

[0022] The two bottom plates 14 at the lower end of the material receiving part are symmetrically arranged and can be opened, so as to facilitate the gypsum in the material receiving frame 13 to be put out through the lower end of the material receiving frame 13. Specifically, when the round rod 23 moves in the direction close to the material receiving frame 13, the round rod 23 drives the swing rod 20 to move, and the swing rod 20 drives the extension plate 19 to move, so that the distance between the two clamping rods 21 increases. At this time, the tension spring 22 is in a further stretched state, and at the same time, the extension plate 19 drives the connecting plate 18 to move, and the round rod 23, the swing rod 20, the extension plate 19 and the connecting plate 18 all move toward the same end of the material receiving frame 13. Since the hook rod 17 is rotatably connected to the material receiving frame 13, the moving directions of the two ends of the hook rod 17 are different, and the lower end of the hook rod 17 is opposite to the moving direction of the round rod 23. Therefore, when the round rod 23 moves in the direction close to the material receiving frame 13, the hook rod 17 will be separated from the fixing column 16. At this time, due to the lack of The lack of cooperation between the hook rod 17 and the fixed column 16 causes the bottom plate 14 to lack the support of the hook rod 17, so that the two bottom plates 14 can be opened, and the gypsum in the material receiving frame 13 can leak downward through the two bottom plates 14; when no pressure is applied to the round rod 23 close to the material receiving frame 13, under the action of the tension spring 22, the hook rod 17 is restored to its original position, that is, the position where the hook rod 17 can be engaged with the fixed column 16. At this time, if the two bottom plates 14 are needed to close the lower end opening of the material receiving frame 13, it is only necessary to rotate the bottom plate 14. Since the lower end of the hook rod 17 has a slope, the fixed column 16 can first squeeze the hook rod 17 along the slope of the lower end of the hook rod 17. After the fixed column 16 passes the slope, under the action of the tension spring 22, the hook rod 17 is prompted to return to its original position, thereby completing the engagement of the hook rod 17 with the fixed column 16, and then completing the closure of the lower end opening of the butt-jointed material frame 13 through the two bottom plates 14.

[0023] Furthermore, guide grooves 24 are symmetrically arranged on the weighing device 12, and the moving wheels 15 on the base plate 14 move along the guide grooves 24. Two moving wheels 15 are arranged on each base plate 14. When the moving wheels 15 enter the guide grooves 24, the left and right shaking of the material receiving frame 13 can be limited, thereby improving the stability of the material receiving frame 13.

[0024] Furthermore, a positioning plate 25 is provided at the end of the guide groove 24. When the moving wheel 15 abuts against the positioning plate 25, that is, the moving wheel 15 can no longer move in the guide groove 24, the position of the material receiving frame 13 is positioned. At this time, the conveying equipment 28 can stably put the gypsum into the material receiving frame 13.

[0025] Furthermore, a limit ring 26 is provided on the outer surface of the material receiving frame 13, and the rocker arm 20 is located inside the limit ring 26. The limit ring 26 is used to support the rocker arm 20 to prevent the rocker arm 20 from moving too much. At the same time, the limit ring 26 will not affect the movement of the rocker arm 20 during normal operation.

[0026] Furthermore, a shell 27 is provided on the outer surface of the base 1 , and the first motor 6 is located inside the shell 27 .

[0027] When installing the device, corresponding pits can be set on the ground, and part of the base 1 and the turntable 2 are located in the pits. At the same time, a receiving groove for placing the load-bearing platform 11, the weighing device 12 and the support rod 29 can also be set on the ground, and the upper surface of the weighing device 12 is located in the same plane as the ground, so as to facilitate moving the material receiving part to the weighing device 12.

[0028] The device can load the gypsum in batches into different material receiving frames 13, so that the gypsum does not need to be directly stacked in the gypsum warehouse. When loading, it is only necessary to load the gypsum of the later production batch into the vehicle first, and then load the gypsum of the previous production batch into the vehicle, so as to avoid the gypsum of the previous production batch from being squeezed and stored in the gypsum warehouse for a long time, thereby ensuring that the gypsum can maintain a good use effect.

[0029] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
