Description

[0002] In the field of aluminum electrolytic carbon production, petroleum coke is an important raw material, and its quality directly affects the performance of the final product; therefore, before the raw materials enter the production line, strict sampling and testing must be carried out, and at this time the corresponding petroleum coke raw material sampler will be used; the existing petroleum coke raw material samplers are mostly composed of motors, reducers, frames, connecting shafts, axle pins, auger rods and barrels and other components; the sampler uses a motor and a reducer as a power source, and transports the raw materials into the barrel for sampling through the rotation of the auger rod, and has the characteristics of simple structure and easy operation.

[0003] Chinese patent publication number CN118150226A discloses "A Petroleum Coke Raw Material Sampling Machine".

[0004] The petroleum coke raw material sampler realizes the sampling and storage effect of the petroleum coke raw material entering the sampling tube through the connection of the connecting cover and the connecting tube, and the connection of the connecting tube and the storage tank. Because its storage tank acts on the outside of the sampling tube, after sampling, the sampled raw material can be quickly and conveniently taken out, thereby improving the convenience of use and the operability, facilitating the support operation of the connecting block at the action position on the plug plate to avoid its falling off, improving the stability of the cover on the sampling tube, and under the action of the cover, facilitating the disassembly and assembly of the sampling rod, thereby improving the use effect of the equipment; however, additional timing or inspection is required to know when the storage tank is full, which increases the workload during sampling; furthermore, it is difficult to stop the power source in time when the storage tank is full, thereby causing the loss of electric energy and the damage caused by the idling or overloading of the motor in the sampler; finally, if the excess petroleum coke raw material inside the sampling tube is not cleaned in time, it will also cause the inaccuracy of the later sampling. For this reason, we provide a petroleum coke raw material sampler. Summary of the invention

DETAILED DESCRIPTION

[0037] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0038] like Figure 1-Figure 9As shown, a petroleum coke raw material sampling machine proposed in one embodiment of the present invention mainly includes the following components and their connection relationship: a sampling barrel 1, the top end of which is rotatably connected to the spiral sampling rod 2 through a bearing, so that the spiral sampling rod 2 can rotate freely in the sampling barrel 1; an n-shaped frame 3, fixedly installed at the upper end of the sampling barrel 1, used to support and fix other components; a driving motor 4, fixedly installed at the upper end of the n-shaped frame 3, and a shaft rotating rod 5 is fixedly installed at its output end. The lower end of the shaft rotating rod 5 is fixedly connected to the upper end of the spiral sampling rod 2. When the driving motor 4 is started, it can drive the spiral sampling rod 2 to rotate in the sampling barrel 1, thereby realizing sampling; a discharge pipe 6, which is installed through the outer periphery of the upper end of the sampling barrel 1, is used to lead out the raw materials in the sampling barrel 1; a docking plug 7, which is plugged into the inner wall of the discharge pipe 6, and one end of which is connected through a storage tank 8, which is used to store the derived raw materials; a full material self-detaching mechanism, connected between the discharge pipe 6 and the storage tank 8. The full material self-disengagement mechanism includes a piston disc 9 arranged on the inner wall of the storage tank 8 and a mounting ring 19 fixedly installed on the periphery of the discharge pipe 6. A connecting rod 40 is inserted through the lower end of the storage tank 8, and one end of the connecting rod 40 is fixedly connected to the center surface of the piston disc 9. A U-shaped plate 10 is fixedly installed on the other end of the connecting rod 40, and the U-shaped plate 10 is located on the periphery of the storage tank 8. A fixing rod 11 is fixedly connected to the end of the U-shaped plate 10, and a trapezoidal block 12 is fixedly installed on the upper end of the fixing rod 11. A transverse groove 13 is opened on the upper end surface of the storage tank 8, and a transverse fixing rod 14 is fixedly connected between the two end walls of the transverse groove 13. A spring 15 is sleeved on the periphery of the transverse fixing rod 14, and a movable sleeve block 16 is slidably sleeved on the periphery of the transverse fixing rod 14, and the movable sleeve block 16 is slidably connected at the inner wall of the transverse groove 13. The upper end surface of the movable sleeve block 16 is fixedly connected with an arc plate 17, and the two arc plates 17 on the same storage tank 8 are fixedly installed with a limit arc plate 18 at the opposite arc surfaces. The upper end surface of the mounting ring 19 is provided with a limit groove 20, and the limit arc plate 18 is slidably inserted into the inner wall of the limit groove 20. The two arc plates 17 on the same storage tank 8 are fixedly installed with a touch rod 21 at the opposite arc surfaces, and the end of the touch rod 21 abuts against the inclined surface of the trapezoidal block 12. A reset component is also connected between the storage tank 8 and the U-shaped plate 10, which is used to reset the mechanism after the storage tank is full of materials; a pulling structure is connected between the shaft rotating rod 5 and the storage tank 8, which is used to drive the shaft rotating rod 5 to reverse when the storage tank is full of materials, so as to realize the export of excess raw materials in the sampling tube 1; a timely stop component is connected between the storage tank 8 and the mounting ring 19, which is used to stop the operation of the drive motor 4 in time when the storage tank is full of materials to prevent the motor from idling or overloading.

[0039] In the above technical solution, the driving motor 4 is started, and the spiral sampling rod 2 is driven to rotate in the sampling barrel 1 through the shaft rotating rod 5; the spiral sampling rod 2 rotates to transport the petroleum coke raw material from the bottom of the sampling barrel 1 upward; the raw material is led out from the sampling barrel 1 through the discharge pipe 6; the docking plug 7 guides the led-out raw material into the storage tank 8 for storage; when the raw material in the storage tank 8 reaches a certain amount, the full material self-detachment mechanism is started. The piston disc 9 drives the U-shaped plate 10 and the fixed rod 11 through the movement of the connecting rod 40, and then pushes the trapezoidal block 12. This action triggers the contact between the touch rod 21 and the limit arc plate 18, so that the limit arc plate 18 slides in the limit groove 20, thereby realizing the self-detachment of the raw material.

[0040] It should be noted that when the trapezoidal block 12 is in the initial position, the movable sleeve block 16 pulls the spring 15, so that the spring 15 is in a stretched state, so that the movable sleeve block 16 and the touch rod 21 can move under the reset force of the spring 15 when the trapezoidal block 12 moves downward; and at this time, the limiting arc plate 18 is also completely inserted into the inner wall of the limiting groove 20. When the trapezoidal block 12 drops to the lowest point, the moving distance of the touch rod 21 just fits the distance that the limiting arc plate 18 moves out of the limiting groove 20, so that the storage tank 8 is no longer restricted, and it is convenient to automatically detach when it is full of raw materials.

[0041] Furthermore, the pulling structure includes a limiting ring 27 fixedly mounted on the outer periphery of the shaft rotating rod 5, and a winding disk 28 is rotatably sleeved on the outer periphery of the shaft rotating rod 5, and the lower end surface of the winding disk 28 is placed on the upper end surface of the limiting ring 27, which is used to limit the axial movement of the winding disk 28. A steel wire rope 29 is wound on the winding disk 28, and one end of the steel wire rope 29 is installed with the storage tank 8 to achieve the connection between the storage tank 8 and the winding disk 28. Rectangular through grooves 30 for the steel wire rope 29 to pass through are opened on both side surfaces of the n-shaped frame 3, and a fixed pulley 31 is fixedly mounted on the inner bottom wall of the rectangular through groove 30. The steel wire rope 29 passes through the rectangular through groove 30 and bypasses the fixed pulley 31. The fixed pulley 31 is used to guide the steel wire rope 29, reduce the generation of friction, and ensure the smoothness of pulling.

[0042] In the above technical scheme, in the initial state, the wire rope 29 on the winding drum 28 is in a relaxed state; when sampling is required, the driving motor 4 or other driving device drives the shaft rotating rod 5 to rotate, and the rotation of the shaft rotating rod 5 drives the winding drum 28 to rotate synchronously through the friction force or mechanical connection between the limit ring 27 and the winding drum 28; when the winding drum 28 rotates, the wire rope 29 is wound, and the other end of the wire rope 29 pulls the storage tank 8 up and docks with the discharge pipe 6 on the periphery of the sampling tube 1, which is convenient for later sampling; the wire rope 29 slides on the fixed pulley 31 in the rectangular through groove 30 to reduce friction; after the sampling is completed, the driving motor 4 is reversed, the winding drum 28 releases the wire rope 29, and the storage tank 8 falls freely, thereby judging that the sampling has been completed.

[0043] Furthermore, the specific implementation of the timely stop component is as follows: the timely stop component includes a connecting plate 36 fixedly connected to the periphery of the mounting ring 19 and a resistance rod 38 fixedly connected to the upper end surface of the storage tank 8; a touch switch 37 is fixedly installed on the lower end surface of the connecting plate 36, and the touch switch 37 is electrically connected to the drive motor 4 through a wire to achieve the control of the drive motor 4 by the touch switch 37; the resistance rod 38 is directly below the touch switch 37, and when the storage tank 8 is full of material, the resistance rod 38 will disengage and no longer squeeze the touch switch 37, so that the touch switch 37 is no longer in a press-to-start state, thereby achieving the timely stop of the drive motor 4.

[0044] In the above technical solution, in the initial state, the resistance rod 38 is in a high position, pressing the touch switch 37; when the storage tank 8 is full, the resistance rod 38 descends with the storage tank 8, thereby no longer pressing the touch switch 37, and the driving motor 4 that was originally started stops running.

[0045] It should be noted that when the resistance rod 38 touches and squeezes the touch switch 37, the drive motor 4 is started at this time. If the resistance rod 38 no longer touches and squeezes the touch switch 37, the touch switch 37 will be reset to stop the drive motor 4, thereby stopping the drive motor 4 at the moment when the storage tank 8 is about to be detached, thereby saving electricity.

[0046] Furthermore, the specific implementation of the reset component is as follows: the reset component includes a strip groove 22 vertically opened on the periphery of the storage tank 8, and a vertical fixing rod 23 is fixedly connected between the two end walls of the strip groove 22; a spring 24 is sleeved on the periphery of the vertical fixing rod 23, and a movable sleeve block 25 is slidably sleeved on the periphery of the vertical fixing rod 23, and the movable sleeve block 25 is slidably connected at the inner wall of the strip groove 22 to achieve stable movement of the movable sleeve block 25. The movable sleeve block 25 is welded to the U-shaped plate 10 to achieve synchronous movement of the movable sleeve block 25 and the U-shaped plate 10. One end of the spring 24 is fixedly connected to the end wall of the strip groove 22, and the other end of the spring 24 is fixedly connected to the lower end surface of the movable sleeve block 25. When the raw materials in the storage tank 8 are discharged, the spring 24 will release the elastic force to push the movable sleeve block 25 and the U-shaped plate 10 to reset.

[0047] In the above technical solution, in the initial state, the spring 24 is in a compressed state, and the movable sleeve block 25 and the U-shaped plate 10 are in a certain position; when the raw materials in the storage tank 8 are discharged, the spring 24 releases the elastic force; the spring 24 pushes the movable sleeve block 25 to slide in the strip groove 22; the movable sleeve block 25 drives the U-shaped plate 10 to move to achieve reset.

[0048] Furthermore, a rectangular groove 32 is provided on the upper end surface of the winding disk 28, and a receiving groove 33 is provided on the periphery of the shaft rotating rod 5; an arc block 34 is slidably inserted at the inner wall of the receiving groove 33 to prevent the shaft rotating rod 5 from rotating forward and driving the winding disk 28 to rotate synchronously, so as to achieve the separation of the shaft rotating rod 5 from the winding disk 28 when the shaft rotating rod 5 rotates forward. A spring 35 is fixedly connected between the inner end wall of the receiving groove 33 and one end of the arc block 34. During the forward rotation of the shaft rotating rod 5, the arc block 34 is in a state of compressing the spring 35 and being received at the inner wall of the receiving groove 33. When the steel wire rope 29 pulls the winding disk 28 to rotate in the reverse direction, the arc block 34 is at the inner wall of the rectangular groove 32, thereby achieving the purpose of limiting, so that the winding disk 28 can drive the shaft rotating rod 5 to reverse synchronously, realize the extraction of excess raw materials in the sampling tube 1, and avoid the inaccuracy caused by the mixing of the sampling in the later stage.

[0049] In the above technical solution, in the initial state, the arc block 34 is in the receiving groove 33, compressing the spring three 35; when the shaft rotating rod 5 rotates forward, due to the action of the arc block 34, the winding disk 28 does not rotate with the shaft rotating rod 5; when the wire rope 29 pulls the winding disk 28 to rotate in the opposite direction, the arc block 34 moves out of the receiving groove 33 and enters the rectangular groove 32; the arc block 34 plays a limiting role in the rectangular groove 32, so that the winding disk 28 can drive the shaft rotating rod 5 to reverse synchronously, thereby realizing the extraction of excess raw materials in the sampling tube 1.

[0050] It should be noted that during the forward rotation of the shaft rotating rod 5, the arc block 34 is in a state of compressing the spring three 35 and being stored in the inner wall of the storage groove 33; when the wire rope 29 pulls the winding disk 28 to rotate in the opposite direction, the arc block 34 is located at the inner wall of the rectangular groove 32, thereby serving the purpose of limiting the position, allowing the winding disk 28 to drive the shaft rotating rod 5 to reverse synchronously, thereby realizing the extraction of excess raw materials in the sampling tube 1 and avoiding inaccuracies caused by later sampling and mixing.

[0051] Furthermore, a connecting block 26 is fixedly connected to the upper end of the trapezoidal block 12, which is used to accurately set the moving distance of the touch rod 21; when the touch rod 21 touches the connecting block 26, the moving distance of the touch rod 21 is adapted to the required distance for the limiting arc plate 18 to move out of the limiting groove 20, ensuring that the full material self-disengagement mechanism can accurately and timely respond to the full material state of the storage tank 8; in addition, handles 39 are fixedly installed on the two side surfaces of the n-type frame 3, which is convenient for the operator to hold and move the entire sampler, thereby improving the convenience and flexibility of operation.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
