Description

Technical Field

[0001] The utility model relates to the technical field of waste incineration, in particular to a fuel waste blocking rotation type level detection device for power generation. Background Art

[0002] There are mainly three ways to dispose of domestic waste: sanitary landfill, composting, and incineration for power generation. However, landfill requires a large amount of land resources and is prone to secondary pollution. Composting has a slow treatment speed and a small applicable scale (mostly applied in rural areas). Therefore, incineration for power generation, which consumes less land resources, has a fast treatment speed, less secondary pollution, and can recycle resources, has become the mainstream waste treatment method in the world.

[0003] Before waste incineration, the recycled waste needs to be stored. The storage usually adopts a closed storage structure, such as a waste foundation pit or a large silo, etc., so as to realize waste storage and transfer for the subsequent treatment of waste. In a large silo, it is necessary to monitor the stacking height of waste. Due to the large variety and significant differences in the forms of domestic waste, the accuracy of the existing level detection switches is greatly affected, and mistakes are likely to occur. At the same time, due to the complex situation inside the waste, direct contact with the detection blade is likely to cause entanglement, corrosion, etc., and the equipment is easily damaged.

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

[0024] It includes a detection die mechanism, a transmission mechanism, and a response mechanism that are installed on one side wall of the silo from top to bottom in sequence;

[0025] The response mechanism is used to feedback the stacking height of the garbage below. Specifically, it includes a hinge seat 1 and a limit block 2 fixedly installed on the side wall of the silo. There are two hinge seats 1 and they are symmetrically arranged. A swing shaft 3 is rotatably installed between the hinge seats 1. A swing plate 4 is fixed on the swing shaft 3. One side of the swing plate 4 is fixed on the swing shaft 3, and the other side of the swing plate 4 extends into the silo. The projection of the swing plate 4 is an isosceles trapezoid structure, and the side close to the swing shaft 3 is narrower, so as to obtain a larger feedback area in the silo.

[0026] The swing plate includes a straight plate and an arc plate 5. The straight plate and the arc plate 5 are integrally formed plates. The straight plate is arranged close to the swing shaft 3, and the arc plate 5 is connected to one end of the straight plate away from the swing shaft 3. The arc plate 5 is an arc that arches downward and the side away from the swing shaft 3 is upturned, so that the bottom surface of the arc plate 5 in contact with the garbage is an arc-shaped curved surface that arches downward, avoiding hooking and carrying garbage when lifting, and is not easily hooked by the garbage, or inserted into the garbage pile and affecting the reaction sensitivity.

[0027] In the middle of the top surface of the arc-shaped plate 5, a joint base 6 is fixed. A spherical concave cavity is provided inside the joint base 6. The end surface where the mouth edge of the spherical concave cavity is located is inclined towards the swing shaft 3. A ball head 7 is in rolling fit inside the spherical concave cavity. A top rod 8 is fixed on the ball head 7. The bottom end of the top rod 8 is fixed to the ball head 7. The top rod 8 is a straight rod made of a metal structure.

[0028] The limit block 2 is arranged at the middle position below the two hinge seats 1. A support surface 9 is provided on one side of the limit block 2 close to the inside of the silo. The support surface 9 is an inclined surface that slopes downward. The support surface 9 is used to contact the bottom surface of the swing plate 4 on the side close to the swing shaft 3, so as to restrict the angle at which the swing plate 4 droops downward. When the bottom surface of the swing plate 4 contacts the support surface 9, the swing plate 4 is in its initial state to be inspected, and the lowest height of the bottom surface of the swing plate 4 is the highest material level that the silo needs to alert.

[0029] The transmission mechanism includes a support frame 10 fixedly installed on the inner wall of the silo. The support frame 10 is located above the swing shaft 3 and below the junction box 17. Two symmetrically arranged sliding sleeves 11 are fixed on the support frame 10. A lifting slide rod 12 that slides up and down with it is sleeved inside the sliding sleeve 11. At the top ends of the two lifting slide rods 12, there is an upper cross bar 13 that fixedly connects the two. The upper cross bar 13 and the two lifting slide rods 12 together form a gantry lifting frame that can lift relative to the silo. Coaxial sleeve 15 are respectively provided at the bottom ends of the lifting slide rods 12. The top end of the top rod 8 is fixed with a horizontal shaft 16 perpendicular to it. The two ends of the horizontal shaft 16 are respectively rotatably connected to the two sleeves 15. When the swing plate 4 swings upward, the top rod 8 jacks up, thereby pushing the lifting frame to rise.

[0030] A plurality of vertically extending trigger pieces 14 are equidistantly arranged on the upper cross bar 13. The trigger pieces 14 can be made of rubber sheets or plastic sheets.

[0031] The detection mechanism uses a non-contact type level detection switch, including a junction box 17. The junction box 17 is fixedly installed on the top of the inner wall of the silo. A rotating shaft driven by a micro motor is provided on the side wall of the junction box 17. A detection blade 18 is fixed on the rotating shaft. Feedback is obtained through continuous rotation and capturing obstacles. The above structure is consistent with the non-contact type level switch in the prior art.

[0032] The operation mode of this device is:

[0033] When the bottom surface of the swing plate 4 contacts the limit block 2, the lifting frame is at the bottom end of its lifting stroke, and the trigger piece 14 is away from the rotating detection blade 18;

[0034] When the garbage piled up at the bottom of the swing plate 4 lifts the swing plate 4, the ejector rod 8 is lifted, causing the lifting frame to rise, thereby raising the height of the trigger piece 14, so that the trigger piece 14 hinders the rotation of the detection blade 18, the trigger switch responds, and it is fed back that the garbage in the silo reaches the warning height.

[0035] This device feeds back through the top of the garbage pile on the bottom surface of the swing plate 4. Whether the garbage is soft or hard, whether it is large or small, as long as the piled height reaches the preset height and the swing plate 4 is pushed up, the level alarm can be triggered. At the same time, the wider arc-shaped plate 5 can take care of longer silos, and due to the mechanical resistance transmitted by the ejector rod 8 and the lifting frame, as well as the weight of the swing plate 4 itself, there is a certain degree of insensitivity to the virtual height of the garbage pile. When the garbage is only virtually high in individual areas, the arc-shaped bottom surface of the swing plate 4 can moderately press down and disperse the protruding garbage.
