Description

Technical Field

[0001] This utility model relates to the field of incineration ash encryption technology, and in particular to a high-efficiency and environmentally friendly device for incineration ash encryption. Background Technology

[0002] Incineration ash densification equipment is typically a device specifically designed to process the ash produced after incineration. By compressing, shaping, or otherwise treating the incineration ash, the volume of the ash is reduced and the density is increased, thereby achieving the densification effect. The densified incineration ash forms a relatively dense block or granular shape, which is less likely to generate dust, reducing dust pollution to the environment and air, and helping to protect the surrounding ecological environment and residents' health.

[0003] Traditional incineration ash treatment methods often have many drawbacks. On the one hand, it is difficult to accurately remove larger impurities and incompletely burned substances from the incineration ash, resulting in uneven raw material distribution during subsequent processing, which affects the processing effect. Furthermore, incineration ash is prone to clogging inside the equipment, reducing processing efficiency and increasing processing costs. In addition, the incineration ash densification treatment is not effective. Based on these issues, a high-efficiency and environmentally friendly device for incineration ash densification is proposed for improvement. Utility Model Content

[0005] Specifically, the technical problem to be solved by this utility model is to provide a high-efficiency and environmentally friendly device for densifying incineration ash, so as to solve the current technical problems of difficulty in removing impurities and unburned materials, easy clogging of the device by incineration ash, and poor densification effect.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A high-efficiency and environmentally friendly device for encrypting incineration ash includes an encryption tank. An installation frame is provided on one side of the encryption tank. An ash inlet hopper is fixedly connected to the top of the installation frame. An upper screen plate is fixedly connected to the upper part of the inner wall of the ash inlet hopper, and a lower screen plate is fixedly connected to the lower part of the inner wall of the ash inlet hopper. The encryption tank includes a stirring mechanism for tumbling incineration ash and an encryption mechanism for encrypting incineration ash.

[0008] A protective shell is fixedly installed on the horizontal plate in the middle of the mounting frame. A first ash conveying pipe is fixedly sleeved on one end of the protective shell. The inside of the first ash conveying pipe is connected to the inside of the ash inlet hopper through an ash drop pipe. A dual-shaft motor is fixedly installed on the inner wall of the protective shell. An impeller is fixedly sleeved on the output shaft of one end of the dual-shaft motor. The impeller is rotatably connected to the inner wall of the protective shell.

[0009] The other end of the dual-shaft motor is fixedly sleeved with a first pulley. A belt is meshed on the outer surface of the first pulley, and a second pulley is meshed on the top of the belt. A rotating shaft is fixedly sleeved inside the second pulley. One end of the rotating shaft passes through the side wall of the ash inlet hopper and is fixedly sleeved with several stirring blades.

[0010] As an improved technical solution, several sets of stirring blades are rotatably connected at the top to the screening groove on the inner wall of the upper screen plate with the rotating shaft as the axis, and several sets of stirring blades are rotatably connected at the bottom to the screening groove on the inner wall of the lower screen plate with the rotating shaft as the axis.

[0011] As an improved technical solution, a medicine tube is fixedly sleeved at the center of the top of the encryption tank, a rotary joint is fixedly sleeved at the bottom of the medicine tube, a rotary nozzle is rotatably connected to the inner wall of the rotary joint, and an arc plate is fixedly connected to the bottom of the arc-shaped tubes on both sides of the rotary nozzle.

[0012] As an improved technical solution, a densification fan is fixedly installed on the bottom horizontal plate of the mounting frame. A first air supply pipe is fixedly sleeved at the output end of the densification fan. A second air supply pipe is fixedly sleeved at one end of the first air supply pipe. The top end of the second air supply pipe passes through the bottom wall of the densification tank and extends to the top wall of the densification tank. Several nozzles are fixedly sleeved on the outer surface of the second air supply pipe. The nozzles inside the densification tank face the arc-shaped plate.

[0013] As an improved technical solution, a manual valve is installed inside the first ash conveying pipe, and a second ash conveying pipe is fixedly connected to one end of the first ash conveying pipe.

[0014] As an improved technical solution, an electrically controlled valve is provided at one end of the second ash conveying pipe, and an ash inlet pipe is fixedly connected to one end of the electrically controlled valve.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are:

[0017] 1. In the process of use, this utility model performs preliminary screening of incineration ash through the upper and lower sieve plates, removing larger impurities and incompletely burned substances, ensuring the uniformity and stability of the raw materials for subsequent processing. The setting of the stirring blades can not only break up larger clumps of incineration ash, but also stir incineration ash in different positions, making the screening more uniform, and preventing the ash hopper from clogging. This greatly improves the effect and efficiency of subsequent densification treatment and optimizes the overall operating performance of the equipment.

[0018] 2. In use, this utility model, through the setting of a rotary joint, a rotary nozzle, and an arc-shaped plate, and with the nozzle nozzle on the upper part of the encryption tank facing the arc-shaped plate, causes the airflow to impact the arc-shaped plate, thereby driving the rotary nozzle to rotate under the action of the rotary joint. This increases the range and uniformity of the agent spraying, resulting in a more complex and intense mixing and reaction between the incineration ash, the agent, and the airflow in the tank. On the other hand, it applies pressure to the incineration ash to achieve physical encryption. Under the action of physical and chemical processes, the incineration ash completes efficient and environmentally friendly encryption treatment. Attached Figure Description

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0031] like Figure 1 and Figure 5 As shown in the figure, this embodiment provides a high-efficiency and environmentally friendly device for encrypting incineration ash, including an encryption tank 1. An installation frame 2 is provided on one side of the encryption tank 1. An ash inlet hopper 3 is fixedly connected to the top of the installation frame 2. An upper screen plate 31 is fixedly connected to the upper part of the inner wall of the ash inlet hopper 3, and a lower screen plate 32 is fixedly connected to the lower part of the inner wall of the ash inlet hopper 3. The encryption tank 1 includes a stirring mechanism 6 for tumbling incineration ash and an encryption mechanism 7 for encrypting incineration ash.

[0032] A protective shell 4 is fixedly installed on the horizontal plate in the middle of the mounting frame 2. A first ash conveying pipe 5 is fixedly connected to one end of the protective shell 4. The inside of the first ash conveying pipe 5 is connected to the inside of the ash inlet hopper 3 through the ash drop pipe. A dual-shaft motor 41 is fixedly installed on the inner wall of the protective shell 4. An impeller 42 is fixedly connected to the output shaft of one end of the dual-shaft motor 41. The impeller 42 is rotatably connected to the inner wall of the protective shell 4.

[0033] The other end of the dual-shaft motor 41 is fixedly sleeved with a first pulley 61. A belt 62 is meshed on the outer surface of the first pulley 61. A second pulley 63 is meshed on the top of the belt 62. A rotating shaft 64 is fixedly sleeved inside the second pulley 63. One end of the rotating shaft 64 passes through the side wall of the ash inlet hopper 3 and is fixedly sleeved with several stirring blades 65. The top of the several sets of stirring blades 65 are rotatably connected to the screening groove on the inner wall of the upper screen plate 31 with the rotating shaft 64 as the shaft. The bottom of the several sets of stirring blades 65 are rotatably connected to the screening groove on the inner wall of the lower screen plate 32 with the rotating shaft 64 as the shaft.

[0034] Specifically, the incineration ash is first poured into the ash inlet hopper 3. Under the action of gravity, the incineration ash falls from the ash inlet hopper 3 to the first ash conveying pipe 5. During the falling process, the incineration ash will be preliminarily screened by the upper screen plate 31 and the lower screen plate 32. The upper screen plate 31 can remove larger impurities and incompletely burned substances to ensure the uniformity and stability of subsequent processing. Then, the dual-shaft motor 41 is started, and the output shaft of one end drives the impeller 42 to rotate. The rotation of the impeller 42 generates thrust, which transports the incineration ash that has been preliminarily screened and falls from the ash drop pipe to the subsequent processing position through the first ash conveying pipe 5.

[0035] The output shaft of the other end of the dual-shaft motor 41 drives the first pulley 61 to rotate. The first pulley 61 drives the second pulley 63 to rotate via the belt 62. At the same time, the rotation of the second pulley 63 drives the rotating shaft 64 to rotate, which in turn drives the stirring blade 65 to rotate. During the rotation, the stirring blade 65 can break up the larger clumps of incineration ash on the upper screen plate 31, making the incineration ash more evenly mixed during the screening process and improving the screening effect. On the other hand, it can tumble and stir the incineration ash between the upper screen plate 31 and the lower screen plate 32, so that it finally falls into the first ash conveying pipe 5 through the ash drop pipe. The rotation of the stirring blade 65 in the screening groove on the inner wall of the screen plate can prevent the incineration ash from clogging the ash inlet hopper 3, thereby improving the effect and efficiency of subsequent densification treatment.

[0036] In a further embodiment, a medicine tube 8 is fixedly sleeved at the center of the top of the encryption can 1, and a rotary joint 81 is fixedly sleeved at the bottom of the medicine tube 8. A rotary nozzle 82 is rotatably connected to the inner wall of the rotary joint 81. Arc plates 83 are fixedly connected to the bottom ends of the arc-shaped tubes on both sides of the rotary nozzle 82. An encryption fan 71 is fixedly installed on the bottom horizontal plate of the mounting frame 2. A first air supply pipe 72 is fixedly sleeved at the output end of the encryption fan 71. A second air supply pipe 73 is fixedly sleeved at one end of the first air supply pipe 72. The top end of the second air supply pipe 73 penetrates the bottom wall of the encryption can 1 and extends to the top wall of the encryption can 1. Several nozzles 74 are fixedly sleeved on the outer surface of the second air supply pipe 73. The nozzles 74 inside the upper part of the encryption can 1 are positioned facing the arc plate 83.

[0037] Specifically, the agent tube 8 is used to deliver the agent into the tank. The agent enters from the agent tube 8, passes through the rotary joint 81 and is sprayed out from the rotary nozzle 82. The arc plate 83 is used to receive force and drive the rotary nozzle 82 to rotate.

[0038] The encryption fan 71 is activated, drawing in a large amount of air, which is then transported through the first air supply pipe 72 to the second air supply pipe 73. When the air flows through the second air supply pipe 73 and reaches the nozzle 74, it is ejected at high speed from the nozzle 74. When the high-speed airflow is ejected from the nozzle 74 above the inside of the encryption tank 1, the airflow directly impacts the arc plate 83, thereby driving the rotating nozzle 82 to rotate under the action of the rotating joint 81. This increases the range and uniformity of the agent spraying, resulting in a more complex and intense mixing and reaction between the incineration ash, the agent, and the airflow inside the tank. At the same time, the airflow forms a specific airflow field inside the encryption tank 1, which accelerates the mixing and reaction of the agent and the incineration ash on the one hand, and applies pressure to the incineration ash on the other hand, realizing the physical encryption operation. Under the action of physical and chemical processes, the incineration ash completes the efficient and environmentally friendly encryption treatment.

[0039] In a further embodiment, a manual valve 51 is provided inside the first ash conveying pipe 5, and a second ash conveying pipe 52 is fixedly connected to one end of the first ash conveying pipe 5. An electric control valve 53 is provided at one end of the second ash conveying pipe 52, and an ash inlet pipe 54 is fixedly connected to one end of the electric control valve 53. The ash inlet pipe 54 passes through the top wall of the encryption tank 1 and extends into the interior.

[0040] Specifically, under the power generated by the impeller 42 driven by the dual-shaft motor 41, the incineration ash that falls from the ash discharge pipe after preliminary screening in the ash inlet hopper 3 passes through the first ash conveying pipe 5 and the second ash conveying pipe 52 in sequence. Under the dual control of the manual valve 51 and the electric control valve 53, it is steadily conveyed to the ash inlet pipe 54 and finally enters the ash storage tank 1 for further processing. The operator can manually operate the manual valve 51 to open or close the ash conveying channel or adjust the ash conveying speed according to the actual situation, so as to flexibly control the amount of incineration ash conveyed. The electric control valve 53 is connected to the equipment's automatic control system, which can realize automatic opening and closing and precise control of the ash conveying flow rate.

[0041] In a further embodiment, a discharge pipe 11 is fixedly sleeved at the bottom of the encryption tank 1, and a discharge valve is provided inside the discharge pipe 11.

[0042] Specifically, when unloading is required, the operator can open the unloading valve according to the actual situation, so that the densified incineration ash can be discharged from the unloading pipe 11, ensuring the safe and orderly unloading process.

[0043] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
