Technical Field
[0001] The present application relates to the field of chemical reagent processing technology, and in particular to a chemical reagent cement kiln coordinated disposal system. Background Art
[0002] Cement kiln co-processing is a new waste disposal method proposed by the cement industry. It refers to the process of putting solid waste that meets or meets the requirements for entering the kiln after pre-treatment into the cement kiln, and realizing the harmless disposal of solid waste while producing cement clinker. Cement kiln co-processing technology is widely used.
[0003] Cement kiln co-processing can be used to treat hazardous waste, domestic garbage (including waste plastics, waste rubber, waste paper, waste tires, etc.), urban and industrial sewage treatment sludge, animal and plant processing waste and contaminated soil, etc. Cement kilns have the characteristics of high temperature, good thermal stability and large volume. The use of cement kiln co-processing can not only achieve large-scale harmless disposal of various wastes, but also integrate waste into the cement kiln system for resource utilization.
[0004] However, with the development of science and technology, a large number of hazardous wastes have emerged, such as chemical reagents. These chemical reagents are flammable, explosive, volatile, and highly toxic and corrosive. They will not only cause harm to people, but also easily pollute the environment. Therefore, they need to be handled professionally. The disposal methods of chemical reagents recorded in the relevant technology mainly include incineration and landfill. Chemical reagents are generally placed in packaging boxes for rapid and centralized treatment. For incineration disposal, explosions, leakages and other dangers are prone to occur; while direct landfill will pollute the environment and does not meet environmental protection requirements. As a way to achieve harmless waste treatment, cement kiln co-disposal is a promising direction for treating chemical reagents. How to combine cement kiln co-disposal with chemical reagent treatment to achieve harmless treatment of chemical reagents is an urgent problem to be solved. Summary of the invention

DETAILED DESCRIPTION
[0029] The following is combined with Figure 1-5 This application is described in further detail.
[0030] The present application embodiment discloses a chemical reagent cement kiln coordinated disposal system, referring to Figure 1 and Figure 2 The chemical reagent cement kiln coordinated disposal system includes a grabbing mechanism 1, a conveying device 2, a preheater 3, a decomposition furnace 4, a smoke chamber 5 and a cement kiln 6. The bottom of the preheater 3 is connected to the top of the decomposition furnace 4, one end of the smoke chamber 5 is connected to the vertically arranged decomposition furnace 4, and the other end of the smoke chamber 5 is connected to the horizontally arranged cement kiln 6. The grabbing mechanism 1 is used to grab the chemical reagent box and place the chemical reagent box on the conveying device 2, and the conveying device 2 is used to transport the chemical reagent box into the preheater 3.
[0031] When in use, the grabbing mechanism 1 grabs the chemical reagent box to be processed and places the chemical reagent box on the conveying device 2, and then the conveying device 2 conveys the chemical reagent box to the preheater 3. The preheater 3 increases the temperature of the chemical reagent and destroys the temperature resistance of its structure. Then, the chemical reagent box enters the decomposition furnace 4 for combustion. A part of the components of the chemical reagent can be used as fuel for combustion, and the main components of the chemical reagent can be sent out of the decomposition furnace 4 as raw materials for cement production through the smoke chamber 5 and enter the cement kiln 6. In this way, the chemical reagent cement kiln coordinated disposal system is used to realize closed treatment, thereby achieving the harmless treatment of chemical reagents and also achieving the purpose of waste recycling.
[0032] Specifically, refer to Figure 1 and Figure 2 The conveying device 2 includes a first conveying mechanism 21, an elevator 22 and a second conveying mechanism 23. The first conveying mechanism 21 is arranged near the bottom of the elevator 22, and the second conveying mechanism 23 is arranged near the top of the elevator 22. The grabbing mechanism 1 is used to place the chemical reagent box from the stacking position onto the first conveying mechanism 21. The elevator 22 is used to receive the chemical reagent box on the first conveying mechanism 21 and transfer it to the second conveying mechanism 23. The second conveying mechanism 23 is used to transport the chemical reagent box to the preheater 3.
[0033] The specific conveying process is as follows: first, the grabbing mechanism 1 obtains a chemical reagent box from the designated position and places it on the first conveying mechanism 21. The first conveying mechanism 21 conveys the chemical reagent box to the abutment position of the first conveying mechanism 21 and the elevator 22. The elevator 22 receives the chemical reagent box on the first conveying mechanism 21 and lifts the chemical reagent box to the height of the second conveying mechanism 23. Then, the elevator 22 conveys the chemical reagent to the second conveying mechanism 23. After being conveyed by the second conveying mechanism 23, the chemical reagent box enters the preheater 3 through the feed port 31. In this way, on the one hand, the work cycle can be shortened and the efficiency of chemical reagent disposal can be improved. On the other hand, manual participation can be reduced, so that manual contact with chemical reagents for a long time is no longer required, and the harm of chemical reagents to personnel can be reduced.
[0034] Reference Figure 1 and Figure 2The lifting machine 22 includes a support 221, a lifting machine 22 mechanism and a receiving platform 223. The lifting machine 22 mechanism is installed on the support 221. The lifting machine 22 mechanism can drive the receiving platform 223 to move up and down in a reciprocating manner. The receiving platform 223 includes a mounting frame 2231 and a transmission mechanism 2232. The transmission mechanism 2232 is installed on the mounting frame 2231. The transmission mechanism 2232 is used to drive the chemical reagent box to move from the end of the mounting frame 2231 away from the second conveying mechanism 23 to the end of the mounting frame 2231 close to the second conveying mechanism 23. The first conveying mechanism 21 transfers the chemical reagent box to the receiving platform 223, and then the lifting machine 22 mechanism can drive the receiving platform 223 to rise to the position of the second conveying mechanism 23. The transmission mechanism 2232 is started to transfer the chemical reagent box to the second conveying mechanism 23. In this way, two reversing transfers are realized, and the chemical reagent box can be accurately lifted to the required height, that is, the installation height of the preheater 3; at the same time, the transportation efficiency is improved.
[0035] It should be noted that in order to improve the stability during the conveying process, the first conveying mechanism 21 and the second conveying mechanism 23 are preferably arranged horizontally. The types of the first conveying mechanism 21, the second conveying mechanism 23 and the transmission mechanism 2232 are not limited, and roller transmission and synchronous belt transmission can be adopted. In this embodiment, the first conveying mechanism 21, the second conveying mechanism 23 and the transmission mechanism 2232 all adopt roller transmission, and the roller transmission mechanism is a structure well known to those skilled in the art. In this embodiment, the structures of the first conveying mechanism 21, the second conveying mechanism 23 and the transmission mechanism 2232 are not described in detail.
[0036] Of course, it is understandable that a plurality of receiving platforms 223 can be provided, and the hoist 22 can drive the receiving platform 223 to perform circular reciprocating motion to achieve continuous transportation of the chemical reagent box. The chemical reagent cement kiln coordinated disposal system also includes a controller (not shown in the figure), which can control the operating speed of the first conveying mechanism 21, the second conveying mechanism 23, the hoist 22 and the transmission mechanism 2232, so that the speed of the chemical reagent box transportation can be adjusted in time, thereby greatly reducing or even avoiding the situation of material blockage in the preheater 3 due to unstable feeding.
[0037] Reference Figure 1 and Figure 2, the grasping mechanism 1 can be a manipulator, a truss robot, etc. Of course, the type of manipulator can be a suction cup type or a clamping type. In this embodiment, only a suction cup manipulator is used as an example for explanation. Since different types of chemical reagents may react when treated, the same type of chemical reagents should be treated together. In order to achieve the above purpose, the grasping mechanism 1 is equipped with an automatic identification system. At the same time, in order to facilitate the positioning of the grasping mechanism 1, a stacking rack 7 is also provided on one side of the grasping mechanism 1. The grasping mechanism 1 identifies the chemical reagent box on the stacking rack 7, absorbs the corresponding chemical reagent box and transfers it to the first conveying mechanism 21. That is, from palletizing to conveying to decomposition, there is no need for staff to touch the chemical reagent box throughout the process.
[0038] Of course, placing the chemical reagent boxes on the stacking rack 7 can also be automated, that is, the palletizer stacks the chemical reagent boxes on the pallet as required, and the loading conveyor line conveys the pallet and the chemical reagent boxes on the pallet to the stacking rack 7. In this embodiment, no specific description is given.
[0039] Reference Figure 1 and Figure 3 Furthermore, the preheater 3 is provided with a feed port 31 and a discharge port 32. The discharge port 32 is located below the feed port 31 and is connected to the top of the decomposition furnace 4. The chemical reagent box enters the preheater 3 through the feed port 31. The decomposition furnace 4 and the preheater 3 are connected by a gas pipe 8. The high-temperature gas generated by the combustion in the decomposition furnace 4 enters the preheater 3 through the gas pipe 8. These high-temperature gases are used to preheat the chemical reagent box to increase the temperature of the chemical reagent.
[0040] Reference Figure 1 and Figure 3 The connection position between the gas delivery pipe 8 and the preheater 3 is close to the bottom of the preheater 3, so that the high-temperature gas flows from bottom to top, which can extend the preheating time of the chemical reagent box and achieve a better preheating effect. Of course, these high-temperature gases will be processed to ensure that no harmful gases enter the preheater 3 again.
[0041] Reference Figure 1 and Figure 3 A plurality of guide plates 9 are arranged in the preheater 3 along the height direction of the preheater 3. Each guide plate 9 is arranged at an angle. Each guide plate 9 is arranged in a staggered manner, so that the chemical reagent box falls along a wavy track. In this way, under the action of the plurality of guide plates 9, the chemical reagent box falls along the wavy track, which reduces the impact of the fall and prolongs the heating time, thereby increasing the temperature of the chemical reagent as much as possible and achieving a better preheating effect.
[0042] Reference Figure 1 and Figure 3In order to further improve the transportation convenience of the chemical reagent box between the second conveying mechanism 23 and the preheater 3, the feed port 31 of the preheater 3 is also provided with a material unloading assembly 10. Specifically, the material unloading assembly 10 includes a hopper 101 and a conveying pipe 102. The hopper 101 and the conveying pipe 102 are integrally formed. The end of the conveying pipe 102 away from the hopper 101 is connected to the feed port 31. The hopper 101 is not higher than the height of the second conveying mechanism 23. In this way, the chemical reagent box falls from the second conveying mechanism 23 into the hopper 101, and then enters the preheater 3 through the conveying pipe 102. Moreover, the conveying pipe 102 is arc-shaped, which effectively reduces the speed at which the chemical reagent box enters the preheater 3 and improves the preheating effect.
[0043] Reference Figure 1 and Figure 4 An isolation conveying assembly 11 is also provided between the discharge port 32 of the preheater 3 and the decomposition furnace 4. The isolation conveying assembly 11 can improve the sealing performance of the connection between the preheater 3 and the decomposition furnace 4, and at the same time can ensure that the gas or other substances in the decomposition furnace 4 will not enter the preheater 3.
[0044] Specifically, the isolation conveying assembly 11 includes a hollow isolation chamber 111, a first gate 112 and a first telescopic driving member 113; the upper end of the isolation chamber 111 is connected to the discharge port 32, the lower end of the isolation chamber 111 is connected to the top of the decomposition furnace 4, the first gate 112 is horizontally arranged and slidably connected to the isolation chamber 111, and the first telescopic driving member 113 is installed on the outer wall of the isolation chamber 111, and is used to drive the first gate 112 to slide; when the first gate 112 completely slides into the isolation chamber 111, a sealing effect can be achieved, and the first gate 112 can divide the isolation chamber 111 into two non-communicating chambers. The design of the isolation chamber 111 and the first gate 112 can achieve a sealing effect, which effectively solves the problem of a large amount of gas overflowing after the chemical reagent box is put into use.
[0045] Further, refer to Figure 1 and Figure 4 The isolation conveying assembly 11 also includes a second gate 114 and a second telescopic drive 115. The second gate 114 is horizontally arranged and slidably connected to the isolation chamber 111. The second telescopic drive 115 is installed on the isolation chamber 111 to drive the second gate 114 to slide. The second gate 114 is located below the first gate 112. There is a gap between the first gate 112 and the second gate 114 for the chemical reagent box to be placed. The chemical reagent box first reaches the top of the first gate 112, the first gate 112 opens, and the chemical reagent box enters the gap between the first gate 112 and the second gate 114. At this time, the first gate 112 is closed, the second gate 114 is opened, and the chemical reagent box enters the decomposition furnace 4. At the same time, the second gate 114 is closed, so as to further solve the problem of a large amount of gas overflowing after the chemical reagent box is put into place.
[0046] Of course, the first telescopic driving member 113 and the second telescopic driving member 115 are linear driving members, and can adopt cylinders, electric cylinders, electric push rods, etc. In this embodiment, the first telescopic driving member 113 and the second telescopic driving member 115 are not limited.
[0047] Reference Figure 1 and Figure 4 The isolation conveying assembly 11 also includes a first detection device (not shown in the figure) and a second detection device (not shown in the figure). The first detection device and the second detection device are both used to detect the chemical reagent box. The first detection device and the detection device are both installed on the inner wall of the isolation chamber 111. The first detection device is located above the first gate 112, and the second detection device is located between the first gate 112 and the second gate 114. The first detection device and the second detection device are both electrically connected to the controller, and the first telescopic drive member 113 and the second telescopic drive member 115 are also electrically connected to the controller. When the first detection device detects the chemical reagent box, the controller controls the first gate 112 to open, and the chemical reagent box enters the gap between the first gate 112 and the second gate 114. At this time, after the second detection device detects the chemical reagent box, the controller controls the first gate 112 to close and controls the second gate 114 to open, so that the chemical reagent box can fall into the decomposition furnace 4. In this way, the automatic opening and closing of the first gate 112 and the second gate 114 are realized. The first gate 112 and the second gate 114 act in a complementary manner. The second gate 114 can only be opened when the first gate 112 is closed. The purpose of automatic transportation and air locking is achieved by opening and closing.
[0048] Of course, the controller can be a PLC controller, and the first detection device and the second detection device can both be infrared recognition detectors, or other types of sensors that meet the requirements. Magnetic limiters can also be installed on the first telescopic drive member 113 and the second telescopic drive member 115 to ensure the accuracy of operation.
[0049] Reference Figure 4 and Figure 5 A reduction wheel 12 is also rotatably connected in the isolation chamber 111. The reduction wheel 12 is located above the first gate 112. A driving motor 13 is installed on the outer wall of the isolation chamber 111. The driving motor 13 drives the reduction wheel 12 to rotate. The reduction wheel 12 includes a central axis 121 and a plurality of reduction blades 122. The reduction blades 122 are arranged along the length direction of the central axis 121. The reduction blades 122 are evenly spaced along the circumference of the central axis 121. The chemical reagent box falls from the discharge port 32 onto the reduction wheel 12, which reduces the falling speed of the chemical reagent box and plays a buffering role, thereby preventing the chemical reagent box from falling directly from the discharge port 32 onto the first gate 112, and can effectively reduce the impact damage to the first gate 112 and the chemical reagent box.
[0050] Of course, the decomposition furnace 4, the smoke chamber 5 and the cement kiln 6 are all products well known to those skilled in the art, and will not be described in detail in this embodiment.
[0051] The implementation principle of the chemical reagent cement kiln coordinated disposal system of the present application embodiment is as follows: when processing chemical reagent boxes, the palletizer stacks each chemical reagent box on the pallet as required, and the loading conveyor line conveys the pallet and the chemical reagent box on the pallet to a specified position; the grabbing mechanism 1 identifies and grabs the chemical reagent boxes of the same type in turn, and places the chemical reagent boxes on the first conveying mechanism 21 in turn, the first conveying mechanism 21 conveys the chemical reagent box to the receiving platform 223, the lifting mechanism 22 raises the receiving platform 223 to a preset height, and the transmission mechanism 223 2 is started, and the chemical reagent box is conveyed to the second conveying mechanism 23; the second conveying mechanism 23 continues to convey, and the chemical reagent box falls from the second conveying mechanism 23 into the hopper 101 and enters the preheater 3 through the conveying pipe 102 to achieve preheating, and then enters the decomposition furnace 4 for treatment through the reduction wheel 12, the first gate 112 and the second gate 114 in sequence, and a part of the components of the chemical reagent can be used as fuel for combustion, and the main components of the chemical reagent can be used as raw materials for cement production and sent out from the decomposition furnace 4 through the smoke chamber 5 to the cement kiln 6. In this way, the chemical reagent cement kiln coordinated disposal system is used to achieve closed treatment, thereby achieving the harmless treatment of chemical reagents and also achieving the purpose of waste recycling.
