Description

Technical Field

[0001] The invention relates to the technical field of ship unloader unloading, in particular to a screw ship unloader quantity control system and a hopper type quantity control device. Background Art

[0002] In the coal transportation system of thermal power plants, most of the power plants along the river and the coast use coal transportation by ship to supply fuel. The docks and various ship unloading devices on them are the main equipment for unloading coal in power plants. At present, the main ship unloading devices used are grab and screw ship unloaders. Among them, the screw ship unloader, as a relatively new technical equipment, has the advantages of simple operation, fully enclosed operation and good environmental protection performance. It greatly reduces the shortcomings of the previous grab ship unloader that is easy to raise dust and improves the environmental protection level. The three-stage spiral structure for conveying materials also shortens the material collection cycle, so that the materials can be taken out immediately, and it is also ahead of the grab ship unloader in terms of instantaneous maximum flow. However, the disadvantage of the spiral ship unloader is that it can be taken out immediately. Although the flow rate can be increased, it is impossible to control or maintain the transported coal at a relatively stable flow rate due to the complex conditions inside the cabin, the different dryness and wetness of coal types, and the interference of the operator's manual or automatic operation level. As a result, the discharge of coal fluctuates. Therefore, when two ship unloaders are operating at the same time, the total unloading flow rate has a large difference and an uncertain change cycle, which will lead to uncertain loads on the coal unloading belt and the risk of overload or damage to the motor. At the same time, for the coal transportation equipment below, especially the direct diversion and storage method from the dock to the unit's raw coal bunker, it has a relatively large impact, resulting in unstable flow rates on the lower belts, affecting the efficiency and safety of storage. Summary of the invention

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0039] Example 1

[0040] Reference Figures 1 to 9 , which is the first embodiment of the present invention, provides a screw ship unloader control system, including the following operating steps:

[0041] A hopper and a conveyor belt are arranged between the horizontal screw and the discharge screw;

[0042] Install monitoring equipment inside the hopper and use it to monitor the material height inside the hopper;

[0043] If the monitoring device triggers an alarm, the monitoring device sends a signal to the host computer, and stops the operation of the horizontal screw and the front-end input device through the host computer;

[0044] Start the equipment to vibrate the hopper. After vibrating for the set time, the upper computer stops the equipment from vibrating and starts the operation of the horizontal screw and the front-end input device, and re-monitors and judges the signal input by the monitoring device.

[0045] Specifically, the material discharge effect of the hopper is enhanced through multi-angle vibration to maintain the normal operation of the secondary unloading.

[0046] In summary, at the transition section between the horizontal spiral and the discharging spiral, the storage volume of the coal flow is enlarged through the hopper, and then the variable frequency motor belt conveyor is connected under the hopper, and the motor controls the speed output of the belt conveyor to achieve the effect of controlling the amount of coal. A monitoring device is set in the hopper. When the amount of coal reaches a certain height, the monitoring device will send a signal to the upper computer to stop the upper horizontal spiral and vertical spiral to achieve a protective effect. At the same time, the hopper is vibrated by the device. After the vibration reaches the set time, the upper computer stops the vibration of the device and starts the operation of the horizontal spiral and the front-end input device. The multi-angle vibration can enhance the feeding effect of the hopper, maintain the normal operation of the secondary unloading, avoid problems such as motor overload and blockage caused by material accumulation, and ensure that the equipment is in a stable unloading state.

[0047] A protective cover is installed outside the belt equipment to reduce the impact of weather, water and other factors on the belt, while preventing coal powder from flying out, and controlling the output of the equipment with minimal impact on the original advantages of the screw machine.

[0048] Example 2

[0049] Reference Figure 1 to Figure 7 and Fig. 9 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a hopper type quantity control device for implementing a screw ship unloader quantity control system, including a main body mechanism 100, a temporary suspension mechanism 200 and a short belt conveyor 300;

[0050] The main mechanism 100 includes a mounting plate 101 fixedly connected to the inside of the housing 1, a support rod 102 fixedly connected to the top of the mounting plate 101, and a slip ring 103 fixedly connected to one end of the support rod 102. A driving component 104 is provided at the top of the mounting plate 101, and a driven component 105 is adapted and installed inside the housing 1.

[0051] The suspension mechanism 200 includes a buffer hopper 201 fixedly connected to the inside of the housing 1, a mounting sleeve 202 fixedly connected to the outside of the buffer hopper 201, and a monitoring component 203 arranged inside the mounting sleeve 202;

[0052] Among them, the short belt conveyor 300 is arranged below the buffer hopper 201.

[0053] Specifically, the driving component 104 includes a motor 104a adapted to be installed on the top of the mounting plate 101, a driving shaft 104b fixedly connected to the output end of the motor 104a, and a gear 104c fixedly connected to the outside of the driving shaft 104b, an annular guide groove 104d is provided on the outside of the driving shaft 104b, a reciprocating component 104e is provided at the top of the driving shaft 104b, and a reset component 104f is provided at the top of the driving shaft 104b.

[0054] Furthermore, the driven component 105 includes a support frame 105a fixedly connected to the inside of the shell 1, a gear ring 105b rotatably connected to the top of the support frame 105a, and a side rod 105c fixedly connected to the outside of the support frame 105a, one end of the side rod 105c is fixedly connected to a mounting frame 105d, a vibration assembly 105e is provided at the top of the gear ring 105b, and an adjustment assembly 105f is adapted and installed inside the mounting frame 105d.

[0055] Furthermore, the vibration assembly 105e includes a mounting base 105e-1 fixedly connected to the top of the gear ring 105b, a rotating shaft 105e-2 rotatably connected to the inside of the mounting base 105e-1 through a torsion spring, and a pressure rod 105e-3 fixedly connected to the outside of the rotating shaft 105e-2, a connecting rod 105e-4 is fixedly connected to the outside of the rotating shaft 105e-2, and a rubber ball 105e-5 is fixedly connected to the top of the connecting rod 105e-4.

[0056] Preferably, the monitoring component 203 includes a threaded rod 203a threadedly connected to the mounting sleeve 202, a monitoring probe 203b adapted to be mounted at one end of the threaded rod 203a, and a screw head 203c fixedly connected to the outer side of the threaded rod 203a;

[0057] Among them, the long rod 104e-4 is located on the right side with the monitoring probe 203b as the main sight, and the short rod 104e-3 is located on the left side with the monitoring probe 203b as the main sight.

[0058] It should be noted that the adjustment assembly 105f includes a circular ring 105f-1 rotatably connected to the inside of the mounting frame 105d, a bottom block 105f-2 fixedly connected to the bottom end of the circular ring 105f-1, and a side plate 105f-3 fixedly connected to the top end of the circular ring 105f-1, an inclined guide groove 105f-4 is provided at one end of the side plate 105f-3, and one end of the limiting rod 104e-5 is arranged inside the inclined guide groove 105f-4.

[0059] When the upper computer starts the motor 104a, it will drive the gear 104c on the outside of the drive shaft 104b to rotate, and the gear 104c will drive the gear ring 105b to rotate, and the gear ring 105b will drive the top vibration component 105e to rotate. When the rotating pressure rod 105e-3 is squeezed into the bottom block 105f-2, the pressure rod 105e-3 will rotate around the rotating shaft 105e-2 under the action of the squeezing force, and the rubber ball 105e-5 at one end of the connecting rod 105e-4 will be driven to rotate synchronously until the pressure rod 105e-3 and the bottom block 105f-2 are squeezed. After the bottom block 105f-2 is dislocated and separated, the rotating shaft 105e-2 is reset under the elasticity of the torsion spring, which will drive the rubber ball 105e-5 to reset and knock on the cache hopper 201. As the gear ring 105b continues to rotate, the rubber ball 105e-5 will continuously knock on the cache hopper 201 to achieve a vibration effect. The vibration can increase the unloading speed of the material inside the cache hopper 201, ensuring that the motor 104a can empty the material inside the cache hopper 201 after stopping, ensuring that the equipment is in a normal state when resuming unloading.

[0060] In summary, when the upper computer starts the motor 104a, it can drive the rubber ball 105e-5 to continuously knock the cache hopper 201 to create vibration. The vibration can increase the unloading speed of the material inside the cache hopper 201, ensuring that the motor 104a can empty the material inside the cache hopper 201 after stopping, ensuring that the equipment is in a normal state when resuming unloading.

[0061] Example 3

[0062] Reference Figures 1 to 9 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a reciprocating assembly 104e, including a sleeve 104e-1 sleeved on the top of the driving shaft 104b, a ball 104e-2 fixedly connected to the inner wall of the sleeve 104e-1, and a short rod 104e-3 fixedly connected to the top of the sleeve 104e-1, a long rod 104e-4 fixedly connected to the top of the short rod 104e-3, and a limit rod 104e-5 fixedly connected to the outer side of the sleeve 104e-1;

[0063] The sliding sleeve 104e-1 is slidably connected to the inner side of the slip ring 103, and the ball 104e-2 is located inside the annular guide groove 104d.

[0064] Specifically, the reset assembly 104f includes a spring 104f-1 fixedly connected to the top end of the sliding sleeve 104e-1, and a turntable 104f-2 fixedly connected to the bottom end of the spring 104f-1, and the turntable 104f-2 is rotatably connected to the top end of the driving shaft 104b.

[0065] When the motor 104a drives the driving shaft 104b to rotate, the design of the ball 104e-2 and the annular guide groove 104d can drive the sleeve 104e-1 to slide back and forth up and down inside the slip ring 103. When the sleeve 104e-1 slides upward to drive the long rod 104e-4 to move, the long rod 104e-4 can be made to fit against the surface of the screw head 203c, making it impossible for the screw head 203c to reverse. This can ensure that when the cache hopper 201 vibrates, the monitoring probe 203b will not become loose, thereby avoiding secondary operations by personnel.

[0066] Even during normal use, when the threaded rod 203a reverses and causes the monitoring probe 203b to loosen, the special position design of the long rod 104e-4 can squeeze the loosened screw head 203c during the sliding process of the long rod 104e-4. At this time, the rotation of the screw head 203c drives the threaded rod 203a to tighten, ensuring the stability of the monitoring probe 203b after installation.

[0067] When the long rod 104e-4 drives the screw head 203c to be completely tightened, causing one end of the long rod 104e-4 to be at the top of the surface of the screw head 203c, the short rod 104e-3 will also be in contact with the other side surface of the screw head 203c, thereby ensuring the stability of the monitoring probe 203b during the vibration of the buffer hopper 201.

[0068] After the motor 104a stops running, the elasticity of the spring 104f-1 will drive the sleeve 104e-1 to completely reset, so that the long rod 104e-4 is completely out of contact with the screw head 203c. The monitoring probe 203b can be disassembled, inspected and installed when the entire equipment is shut down.

[0069] While the sleeve 104e-1 slides back and forth up and down, the design of the limit rod 104e-5 and the inclined guide groove 105f-4 can drive the ring 105f-1 to rotate back and forth. The reciprocating rotation of the ring 105f-1 will adjust the position of the bottom block 105f-2, thereby changing the squeezing position of the bottom block 105f-2 and the pressure rod 105e-3, and finally changing the position of the rubber ball 105e-5 hitting the cache hopper 201, thereby achieving all-round vibration and further increasing the discharge speed of the material inside the cache hopper 201.

[0070] In summary, when the material is blocked, the equipment can stop the conveying of the front-end material to avoid the overload and short circuit of the equipment. The speed of the buffer hopper 201 can also be increased through all-round vibration. During the vibration process, the stability of the installation of the monitoring probe 203b can be ensured, and the motor 104a can be ensured to empty the material inside the buffer hopper 201 after shutdown, so that the equipment is in a normal state when resuming unloading.
