Description

Technical Field

[0001] The present invention relates to the technical field of solid waste treatment, and particularly to a solid waste treatment device based on co-processing in a cement kiln. Background Art

[0002] The cement kiln makes a series of complex physical and chemical changes to the raw materials through high-temperature calcination, and then produces cement. In order to reuse solid waste, the solid waste is co-processed with the cement kiln. Solid waste includes industrial solid waste, agricultural solid waste, and domestic solid waste. Among them, steel slag particles in industrial solid waste are often co-processed with the cement kiln. The reason is that the main chemical components of steel slag particles include calcium oxide, silicon dioxide, aluminum oxide, iron oxide, etc. In cement production, calcium oxide is an important component for forming the main clinker mineral tricalcium silicate. Therefore, in some practices of co-processing in a cement kiln, industrial solid waste can provide part of the calcium source required for the formation of cement clinker, reducing the demand for traditional limestone raw materials. At the same time, it also reduces the potential harm to the environment caused by the stacking of industrial solid waste, realizes the resource utilization of industrial solid waste, achieves the purpose of energy conservation, emission reduction, and environmental protection, and plays an important role in promoting resource recycling and environmental protection. The existing devices for treating industrial solid waste are still relatively simple, and the coordinated operation of crushing and separation is not smooth enough.

Two symmetric second springs 711 are fixedly connected between the electromagnetic fixing plate 77 and the electromagnetic extrusion plate 714. The magnetic isolation plate 78 is used to prevent the repulsive force between the permanent magnet block 79 and the electromagnetic fixing plate 77 from having an impact, and the rubber pad 710 can prevent the permanent magnet block 79 from directly contacting the electromagnetic extrusion plate 714, preventing the permanent magnet block 79 or the electromagnetic extrusion plate 714 from being damaged due to collision.

[0033] Among them, the first sliding rheostat 75 includes a first resistance plate 751 fixedly connected inside the first sliding groove 73. The outer wall of the first resistance plate 751 is slidably connected with a first conductive sheet 752. The other end of the first conductive sheet 752 is fixedly connected to a first extension plate 753 fixedly connected to the top end of the electromagnetic extrusion plate 714. The first conductive sheet 752 and the first resistance plate 751 are electrically connected to a PLC controller to form a first detection circuit. During the sliding process of the first conductive sheet 752 downward along the first resistance plate 751, the resistance of the first sliding rheostat 75 in the first detection circuit gradually decreases. A blocking plate 754 is slidably connected to the inner wall of the first sliding groove 73. The top end of the blocking plate 754 is fixedly connected to the bottom end of the first conductive sheet 752. The outer wall of the containing plate 71 is in sliding contact with the outer wall of the blocking plate 754.

[0034] Among them, the second sliding rheostat 76 includes a second resistance plate 761 fixedly connected in the second chute 74.

The second conductive sheet 762, the second resistance plate 761 and the PLC controller are electrically connected to form a second detection circuit. During the downward sliding process of the second conductive sheet 762 on the second resistance plate 761, the resistance of the second sliding rheostat 76 in the second detection circuit gradually decreases. The upper and lower inner walls of the second chute 74 are respectively fixedly connected with a first telescopic plate 764 and a second telescopic plate 765. The telescopic end of the first telescopic plate 764 is fixedly connected to the bottom end of the second conductive sheet 762. The bottom end of the second telescopic plate 765 is fixedly connected with a blocking block fixedly connected to the top end of the second conductive sheet 762, and the blocking block is slidably connected with the inner wall of the second chute 74. The PLC controller is electrically connected to the electromagnetic fixing plate 77 and the electromagnetic pressing plate 714 to form a crushing circuit. The PLC controller is electrically connected to the second sliding rheostat 76 to form a first adjustment circuit. The electromagnetic pressing plate 714 is electrically connected to the first sliding rheostat 75 to form a second adjustment circuit. Among them, the horizontal resistance values of the second resistance plate 761 and the first resistance plate 751 are the same (as Figure 9 shown in the figure, the resistance values at a and b are the same, and the resistance values of the second resistance plate 761 and the first resistance plate 751 below a and b are also the same).

[0035] Among them, on the opposite sides of the two partition plates 82, support bars 712 are symmetrically and fixedly connected. The top ends of the support bars 712 can intermittently contact the bottom end of the containing plate 71. A piezoelectric ceramic sheet 713 is fixedly connected to the bottom end of the containing plate 71. The piezoelectric ceramic sheet 713 is electrically connected to the PLC controller to form a vibration circuit. Among them, the piezoelectric ceramic sheet 713 has a special crystal structure. When an electric field is applied to the piezoelectric ceramic sheet 713, that is, when it is energized, the inverse piezoelectric effect will occur, resulting in its vibration.

[0036] The separation mechanism 8 separates the crushed qualified solid waste particles from the unqualified solid waste particles and separates the magnetic impurities. Refer to Figures 2 to 4 , the separation mechanism 8 includes two partition plates 82 fixed in the crushing box 2. The partition plates 82 sequentially divide the crushing box 2 into a blowing space 3, a crushing space 4 and a collection space 5. A blowing pump 81 is arranged in the blowing space 3. First filter ports 83 and second filter ports 814 are respectively opened on the outer walls of the two partition plates 82. The inner wall of the first filter port 83 is fixedly connected with a first filter plate 84. The inner walls of the second filter ports 814 are fixedly connected with a second filter plate 85 and a third filter plate 86, and the second filter plate 85 is in sliding contact with the third filter plate 86.

[0037] The separating mechanism 8 further includes a blowing hood 87 fixedly connected to the outer wall of the partition plate 82 near the first filter plate 84. The blowing end of the blowing pump 81 is fixedly communicated with the outer wall of the blowing hood 87. The air extraction end of the blowing hood 87 is fixedly communicated with an air extraction pipe 88. The other end of the air extraction pipe 88 passes through the inner wall of the crushing box 2 and extends to the outside. Two symmetrically arranged upper and lower micro electric telescopic rods 89 are fixedly connected to the inner wall of the second filter port 814 of the third filter plate 86. The telescopic ends of the two micro electric telescopic rods 89 are fixedly connected to the outer wall of the third filter plate 86. The PLC controller is electrically connected to the micro electric telescopic rods 89 and the blowing pump 81 to form a first separation loop. In the initial state, the filter holes of the third filter plate 86 and the second filter plate 85 are staggered, so the solid waste particles will not be blown into the blowing space.

[0038] A connecting groove 810 communicating with the inside of the crushing space 4 is formed in the outer wall of the crushing box 2. A large electric telescopic rod 811 is fixedly connected to the top end of the crushing box 2. A receiving frame 812 is slidably connected to the inner wall of the connecting groove 810. A push plate 813 is fixedly connected to the outer wall of the receiving frame 812 away from the crushing box 2. The outer wall of the push plate 813 is fixedly connected to the telescopic end of the large electric telescopic rod 811. The large electric telescopic rod 811 is electrically connected to the PLC controller to form a second separation loop. The receiving frame 812 can cooperate with the outer wall of the crushing box 2 to close the crushing space 4 when not working.

[0039] A blanking port 9 communicating with the conveying pipe 6 is formed at the bottom end of the crushing box 2. A connecting frame 10 is fixedly connected to the bottom end of the crushing box 2, and the connecting frame 10 is located between the feeding port of the conveying pipe 6 and the blanking port 9. A collecting groove 11 is arranged inside the collecting space 5, and a communication port communicating with the blanking port 9 is formed at the bottom end of the collecting groove 11. A blower is fixedly communicated with one end of the conveying pipe 6 close to the crushing box 2. Two symmetrically arranged feeding ports communicating with the crushing space 4 are formed in the outer wall of the crushing box 2, and a sealing plug is detachably arranged in the feeding port. The conveying pipe 6 and the blower form a pneumatic conveyor.

[0040] When treating the solid waste particles, first, the solid waste particles need to be crushed before being co-processed by the cement kiln. The reason is that in the cement kiln, the solid waste particles need to undergo a series of physical and chemical changes. After being crushed, the solid waste particles have a smaller particle size and are heated more evenly in the kiln, which is beneficial to generating more stable cement clinker and avoiding fluctuations in cement quality caused by uneven composition. After treating the solid waste particles in this application, the treated solid waste particles can be directly transported to the cement kiln or collected in a storage box and then transported to the cement kiln together with other materials.

[0041] The following is the specific process of crushing and screening the solid waste particles:

[0042] First, the solid waste particles are put into the crushing space 4 in the crushing box 2 through the feed inlet, so that the solid waste particles are on the placing plate 71. And during the putting process, the solid waste particles need to be spread out as flat as possible. During the putting process, the piezoelectric ceramic sheet 713 is electrified to vibrate, so that the solid waste particles above the placing plate 71 vibrate and become flat. As the vibration continues, the solid waste particles will gradually tend to occupy the position with the lowest energy (i.e., the low-lying area), that is, a relatively compact and flat state.

[0043] After the putting is completed, the electromagnetic extrusion plate 714 and the electromagnetic fixing plate 77 are electrified through the PLC controller. Then, the electromagnetic fixing plate 77 generates a repulsive force on the electromagnetic extrusion plate 714 and moves downward (where the magnetic isolation plate 78 only magnetically isolates some positions between the electromagnetic fixing plate 77 and the permanent magnet 79, not all). During the downward movement of the electromagnetic extrusion plate 714, it will drive the first extension plate 753 and the first conductive sheet 752 to move downward, so that the first conductive sheet 752 slides downward on the first resistance plate 751. Since the resistance of the first sliding rheostat 75 in the first detection circuit gradually decreases during the downward sliding of the first conductive sheet 752 on the first resistance plate 751, the current passing through the first sliding rheostat 75 gradually increases, and then the current transmitted to the electromagnetic extrusion plate 714 gradually increases, so that the electromagnetic extrusion plate 714 gradually squeezes downward. As long as the electromagnetic extrusion plate 714 moves downward, the current passed into the electromagnetic extrusion plate 714 will continue to increase, making the electromagnetic extrusion plate 714 continue to move downward. When the electromagnetic extrusion plate 714 moves downward and touches the solid waste particles, it will squeeze the solid waste particles through the electromagnetic extrusion plate 714, causing the placing plate 71 to move downward. At the moment when the placing plate 71 moves downward, it will drive the second conductive sheet 762 to slide on the second resistance plate 761, thereby changing the current passing through the second sliding rheostat 76. In the initial state, the second sliding rheostat 76 is in an electrified state.

[0044] The current detection module in the PLC controller will detect the current change of the second sliding rheostat 76 and record the current magnitude at this time. At the same time, the PLC controller detects the current passing through the first sliding rheostat 75 and records the current magnitude at this time. Since the horizontal resistance values of the second resistance plate 761 and the first resistance plate 751 are the same (see above), the current value passing through the first sliding rheostat 75 is subtracted from the current value passing through the second sliding rheostat 76 to obtain the current difference. The calculation module in the PLC controller calculates the thickness of the solid waste particles according to the current difference and controls the current magnitude passed into the electromagnetic extrusion plate 714 according to the thickness of the solid waste particles.

[0045] By continuously pressing down with the electromagnetic pressing plate 714, the solid waste particles will be pressed downward and the containing plate 71 will also be pressed downward. Since the first spring 72 at the bottom of the containing plate 71 will cause the pressing force of the electromagnetic pressing plate 714 on the solid waste particles to gradually increase. The reason is that the first spring 72 is compressed, and the reaction force of the first spring 72 on the containing plate 71 will continue to increase, thereby increasing the pressing force on the solid waste particles. Although the reaction force of the first spring 72 will cause the pressing force to gradually increase, the first spring 72 itself also plays a certain buffering role. It does not apply a huge force instantaneously, but has a gradually changing process. Thus, the impact force on the solid waste particles is reduced through the first spring 72, preventing some solid waste particles from being flattened, so that most particles such as calcium oxide can be pressed into powder and then sent into the cement kiln.

[0046] When the containing plate 71 moves above the support bar 712 and contacts the support bar 712, at this time, the second conductive sheet 762 and the second resistor plate 761 are no longer in contact. Therefore, the current detection module in the PLC controller will not detect current (at this time, the timing module in the PLC controller starts timing). At this time, it is necessary to increase the current of the electromagnetic pressing plate 714 according to the thickness of the solid waste particles (the thicker the solid waste particles, the greater the force required for continuous pressing. The thickness of the solid waste particles is proportional to the pressing force that the solid waste particles need to receive, that is, the greater the current passed into the electromagnetic pressing plate 714. This is because thicker solid waste particles mean that more solid waste particle materials need to be broken. From an energy perspective, breaking solid waste particles requires overcoming the binding force between the particles inside the solid waste particles, and the total binding force inside thicker solid waste particles is greater), so that the electromagnetic pressing plate 714 continues to press the solid waste particles downward (the set pressing time is 10 s to prevent the solid waste particles from becoming flattened due to too long pressing time). After some solid waste particles become flattened, it will affect the passage of the remaining solid waste particles through the filter holes. After the pressing time reaches 10 s, the fixed electromagnetic plate is powered off through the PLC controller. Therefore, the electromagnetic pressing plate 714 does not feel the repulsive force, and the elastic potential energy of the second spring 711 drives the electromagnetic pressing plate 714 to reset up and down. After resetting, the electromagnetic pressing plate 714 is adsorbed by the permanent magnet 79 to prevent the electromagnetic pressing plate 714 from bouncing back and forth.

[0047] The PLC controller is used to control the micro electric telescopic rod 89 to push out the third filter plate 86, so that the filter holes of the third filter plate 86 and the second filter plate 85 coincide and leak out. Then, the PLC controller is used to control the air blowing pump to start, and then blow air into the crushing space 4. The blowing force of the air blowing pump is proportional to the thickness of the solid waste particles. The thicker the solid waste particles are, the greater the blowing force is. At the same time, because the electromagnetic pressing plate 714 does not press the solid waste particles and the placing plate 71, the elastic potential energy of the second spring 711 will cause the placing plate 71 to bounce up and down, and then bounce up the solid waste particles. Then, the air blown by the air blowing pump blows the lighter solid waste particles to the first filter plate 84 and blows them into the collection space 5 through the first filter plate 84. Due to the elasticity of the placing plate 71, it will continuously drive the solid waste particles to jump, so there will be no solid waste particles blocking the filter holes of the first filter plate 84. The blockage of the first filter plate 84 is cleaned by the movement of the placing plate 71. Since the electromagnetic pressing plate 714 is continuously powered on, the electromagnetic pressing plate 714 always has magnetism. At this time, the solid waste particles bounce back and forth. When the solid waste particles with magnetic impurities contact the electromagnetic pressing plate 714, the solid waste particles with magnetic impurities will be adsorbed on the lower surface of the electromagnetic pressing plate 714. The reason for the adsorption is that cement production is an accurate chemical process, and magnetic impurities in the raw materials will have an adverse impact on the quality and performance of cement.

[0048] After pre-testing the elasticity of the placing plate 71, it takes time t to stabilize slowly. Therefore, after the electromagnetic fixing plate 77 is powered off for time t, the PLC controller is used to control the large electric telescopic rod 811 to start. The retraction of the large electric telescopic rod 811 will drive the push plate 813 and the receiving frame 812 to move synchronously, so that the receiving frame 812 enters the crushing space 4 and is located below the electromagnetic pressing plate 714. Then, the PLC controller powers off the electromagnetic pressing plate 714, so that the electromagnetic pressing plate 714 adsorbs the solid waste particles with magnetic impurities and drops them into the receiving frame 812. Then, the PLC controller is used to control the large electric telescopic rod 811 to extend, and then repeat the above process to start secondary crushing.

[0049] The crushed solid waste particles will pass through the collection tank 11 and then fall into the conveying pipe 6. The crushed solid waste particles are conveyed to the cement kiln body 1 through the air blower.

[0050] It should also be noted that the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or elements inherent to such process, method, commodity or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of another identical element in the process, method, commodity or device including the element.

[0051] The above are only embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
