Description

Technical Field

[0001] The utility model relates to the field of garbage incineration technology equipment, in particular to a fuel garbage level monitor for power generation. Background Art

[0002] Generating electricity by burning garbage (mainly referring to sorted domestic garbage) is an important way to establish the resource utilization of urban domestic garbage and the recycling of renewable resources. After the garbage is transported to the incineration plant, it is weighed on the scale and directly unloaded into the garbage storage pit. Since the garbage is piled up in the garbage storage pit for a long time, it will produce strong and harmful odors and need to be recycled and utilized. Therefore, the garbage storage pit adopts a fully enclosed structure, and the material adjustment and lifting, as well as loading and other operations are carried out through the internal crane-operated gripper.

[0003] There are usually multiple closed buildings outside the discharge gate. When the vehicle reaches the discharge gate, the discharge gate is lifted inward, and the vehicle hopper is lifted backward to dump the garbage into the discharge gate. This unloading method requires the grabber in the garbage storage pit to constantly adjust the garbage near the discharge gate to keep the garbage near the discharge gate low, so as to facilitate unloading. Because the foundation pit is large and multiple discharge gates are operating simultaneously and uninterruptedly, it is easy to rely on manual observation to cause untimely adjustments and excessive accumulation of garbage near the discharge gate.

[0023] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0024] Embodiment: A fuel waste level monitor for power generation

[0025] Since garbage is piled in disorder and there are many types of domestic garbage, the garbage may be soft or hard, light or heavy, and of different sizes. Therefore, it is impossible to comprehensively observe the overall garbage stacking situation by using conventional material level detection or distance sensors.

[0026] This monitor adopts a brand-new design, which monitors and warns the height of garbage through the swing angle. The main structure includes a hanging rail 1 hoisted in the garbage storage pit. The hanging rail 1 is installed horizontally, and its extension direction is adapted to the garbage storage pit wall on the side where the unloading door is installed. The hanging rail 1 is an I-shaped hanging rail 1 with a simple structure and is strong and durable.

[0027] The top side of the hanging rail 1 is provided with a support column 2 for hanging the hanging rail 1, and the support column 2 is fixedly installed on the top of the garbage storage pit by bolts. The bottom end of the support column 2 is fixedly connected to the hanging rail 1 by bolts.

[0028] The hanging rail 1 is provided with a moving trolley 3 having a linear travel along its length direction. The moving trolley 3 includes frame plates 4 located on both sides of the hanging rail 1. Two parallel guide wheels 5 are installed on the upper side of each frame plate 4. The guide wheels 5 cooperate with the hanging rail 1 to achieve movement relative to the hanging rail 1. The linear travel structure of the moving trolley 3 adopts wire control. Winches are respectively fixed at both ends of the hanging rail 1. One end of the winch with a cable wound on it is fixed on the moving trolley 3. When it is necessary to move in a certain direction, the winch on this side reels in the cable to pull the moving trolley 3 to move, and the winch on the other side releases the cable to cooperate with the trolley to move. Not limited to this example, a traveling wheel driven by a motor can also be installed on the moving trolley 3, and the traveling wheel can cooperate with the hanging rail 1 to achieve a walking structure.

[0029] Since the gas in the garbage storage pit is humid, the use of a cable is simpler and is not affected by moisture and methane, maintaining better operation and reducing the probability of operation and maintenance.

[0030] An equipment box 7 is fixed to the bottom of the mobile trolley 3, and a U-shaped connecting frame 6 is provided on the top of the equipment box 7. The bottoms of the two frame plates 4 are respectively provided with large bolts 8 passing through them. The top of the connecting frame 6 is provided with a mounting groove that cooperates with the large bolt 8. The bottom end of the large bolt 8 is tightened against the bottom of the mounting groove to fix the connecting frame 6.

[0031] A rotating seat 9 is provided in the equipment box 7, and a rotating shaft 10 is rotatably installed on the rotating seat 9. A fixing sleeve 11 is provided in the middle of the rotating shaft 10 and is vertically connected and fixed thereto. A swing rod 12 is fixed in the fixing sleeve 11. The top end of the swing rod 12 is inserted into the fixing sleeve 11 and is coaxially fixed with the fixing sleeve 11. The swing rod 12 is a round straight rod, and a detachable tow ball 13 is fixed to the bottom end of the swing rod 12.

[0032] A cutout 14 is provided at the bottom of the equipment box 7, and the width of the cutout 14 is adapted to the diameter of the swing rod 12. The top of the cutout 14 is close to the installation position of the rotating shaft 10, and in this example is located at one-third of the position below the equipment box 7, leaving sufficient space for the swing of the swing rod 12. Constraint plates 15 are respectively provided on the two side edges of the cutout 14, and the constraint plates 15 are U-shaped adapted to the extension of the cutout 14. The spacing between the two constraint plates 15 is adapted to the diameter of the swing rod 12, and can restrict the swing rod 12 from swinging within a plane. The cutout 14 is parallel to the hanging rail 1, so that the swing rod 12 can only swing back and forth corresponding to the travel direction as the moving trolley 3 moves.

[0033] In terms of monitoring the swing angle, an angle sensor can be installed on the rotating shaft 10 to capture the change of the swing angle in real time, so as to obtain the height of the swing rod 12 in the swinging state according to the swing rod 12 of a fixed length, thereby obtaining the height of the garbage below. In addition, according to the maximum height limit of the garbage stacking at the unloading position, two position sensors can be set in the equipment box 7. The position sensors are set below the fixed sleeve 11 and are symmetrically arranged relative to the fixed sleeve 11. When the swing rod 12 approaches and releases the position sensor, an alarm is triggered, indicating that the swing amplitude has reached the warning line and the height of the garbage below has reached the point where material transfer must be carried out.

[0034] The swing rod 12 is a hard straight rod, and the bottom end is detachably connected to the tow ball 13, so that the tow ball 13 can be easily replaced.

[0035] The tow ball 13 adopts a hollow structure, which makes it easier to respond to the fluctuations of the garbage pile.

[0036] The drag ball 13 adopts a two-half structure, including a symmetrical and completely identical hemisphere 16, the hemisphere 16 is a hollow hemisphere, a fixed half pipe 17 extending into the ball is provided at the top center of the hemisphere 16, the fixed half pipe 17 is semicircular and has an outer pipe opening 18 located at the top of the hemisphere 16 at the top, and an inner pipe opening 19 located inside the hemisphere 16 and close to the bottom is provided at the bottom of the fixed pipe, and a lower stopper 20 is provided at the bottom of the swing rod 12, and a fixed half pipe 17 is provided above the lower stopper 20. The upper stopper 21 of the lower stopper 20 is provided, and the spacing between the lower stopper 20 and the upper stopper 21 is greater than the length of the fixed half pipe 17. When the two hemispheres 16 are closed into a sphere and fixed, the two fixed half pipes 17 form a closed circular pipe. The inner diameter of the fixed half pipe 17 corresponds to the diameter of the swing rod 12, which can ensure that the hemisphere 16 and the swing rod 12 are in the same direction and have the same diameter. The upper stopper 21 is located above the outer pipe opening 18, and the lower stopper 20 is located below the inner pipe opening 19, thereby realizing the detachable fixation of the bottom end of the swing rod 12 and the towing ball 13. This fixing structure is simple and fast, easy to quickly disassemble, and can allow the towing ball 13 to drive the swing rod 12 to swing with the rise and fall of the garbage.

[0037] The top side of the hemisphere 16 is provided with a lug 22 which is symmetrical with respect to the fixed half pipe 17 , and a stud bolt 23 runs through the lug 22 . The lug 22 of the two hemispheres 16 is fixed by the stud bolt 23 to achieve the fixation of the two hemispheres 16 .

[0038] The top and bottom ends of the fixed half pipe 17 are respectively provided with reinforcing plates 24, one end of the reinforcing plate 24 is connected to the fixed half pipe 17, and the other end of the reinforcing plate 24 is connected to the inner wall of the hemisphere 16. The reinforcing plate 24 is not limited to the structure, and is mainly used to strengthen the strength of the fixed half pipe 17 to prevent the fixed half pipe 17 from deformation.

[0039] The drag ball 13 can be a plastic ball, a rubber ball, or a metal ball, and the above structures are easy to process.

[0040] A wedge-shaped clamping head 25 is provided on the bottom side of the circular edge of one hemisphere 16, and a corresponding clamping groove 26 cooperating with the clamping head 25 is provided on the bottom side of the circular edge of the other hemisphere 16. During installation, the clamping head 25 is matched with the clamping groove 26 at the position of the fixed lug 22 to strengthen the spherical closed structure.

[0041] Through this monitoring device, when the mobile trolley 3 drives the entire device to move along the unloading line, the towing ball 13 falls on the garbage pile. As it moves along the unloading line, the towing ball 13 is driven by the swing rod 12 to drag on the garbage pile and rise and fall with the garbage pile. When the pile is high, the swing amplitude of the swing rod 12 is large, and when the pile is low, the swing amplitude is small, so that the height of the garbage pile can be obtained. When the garbage pile is too high and may affect the unloading, timely manual intervention is required.

[0042] This device can realize the digital collection and monitoring of the height of garbage piles along the unloading line, replacing the disadvantages that are difficult to discover in time and may be missed by manual observation, ensuring the smooth unloading and avoiding excessive leakage of pollution sources (mainly gas) caused by the garbage truck waiting for a long time to move the materials due to the excessively high piles and the unloading door being opened for a long time.
