Description

Technical Field

[0001] This utility model relates to the technical field of unloading devices, and in particular to a double-layer airlock unloading device. Background Technology

[0002] The TC-1164 grate cooler configured in our company's kiln system is an early third-generation grate cooler. The air chamber unloading uses an old-fashioned reducer and linkage mechanism. Later, the linkage and transmission components frequently failed, causing untimely unloading. Manual unloading was subsequently adopted, but due to worker negligence and busy schedules, unloading was sometimes forgotten, leading to equipment damage. Regardless of whether it's the reducer and linkage mechanism or manual unloading, the poor airlock effect of the unloading device results in dust emissions. This unloading method not only affects the safe operation of the equipment but also poses an environmental safety hazard. Furthermore, the installation of the device requires multiple bolts, necessitating precise alignment and bolt installation, making it quite laborious.

[0003] Therefore, those skilled in the art have provided a double-layer airlock unloading device to solve the problems mentioned in the background art. Utility Model Content

[0017] Furthermore, a plurality of adjusting bolts are provided on one side of the outer wall of the second valve plate, and the adjusting bolts and the first valve plate cooperate with each other;

[0018] The above technical solution allows for the use of four adjusting bolts to adjust the vertical height of the first valve plate.

[0019] Furthermore, an intermediate housing is provided between the first valve body and the second valve body, and an observation door is provided on one side of the outer wall of the intermediate housing;

[0020] The above technical solution uses an intermediate shell for the first layer of sealing, and an observation door to observe the unloading process inside the device.

A second valve plate 105 is installed inside the first valve body 3 and the second valve body 7. A first valve plate 104 is installed on one side of the outer wall of the second valve plate 105. A connecting assembly 102 is connected to one end of the cylinder 101, and a connecting rod 103 is connected to the other end of the connecting assembly 102. The other end of the connecting rod 103 is connected to the second valve plate 105. This mechanism prevents dust from being emitted during unloading from the ash hopper, improves the airlock effect, enables automatic material discharge, reduces dust, and avoids equipment accidents and environmental safety incidents. Track assemblies are installed on both sides of the inner walls of the first valve body 3 and the second valve body 7. The first valve plate 104 and the second valve plate 105 are slidably connected to the track assembly 106, which facilitates the movement of the first valve plate 104 and the second valve plate 105 through the track assembly 106, thereby facilitating the opening and closing of the valve body. A valve plate shaft 12 is provided on one side of the outer wall of the second valve plate 105, and a valve plate bushing 11 is provided on the outer wall of the valve plate shaft 12. The valve plate bushing 11 passes through the first valve plate 104, and fixes the first valve plate 104 to the second valve plate 105 through the bushing and the pin. A plurality of adjusting bolts 10 are provided on one side of the outer wall of the second valve plate 105. The adjusting bolts 10 and the first valve plate 104 cooperate with each other, and four adjusting bolts 10 can be set to adjust the vertical height of the first valve plate 104.

[0036] Reference Figure 1 , Figure 2 and Figure 5The positioning mechanism 2 includes a triangular locking block 201. Cavities 203 are provided at both ends of one side of the outer wall of the first valve body 3 and the second valve body 7. A spring 202 is connected to one side of the inner wall of the cavity 203, and the triangular locking block 201 is connected to the other end of the spring 202. The triangular locking block 201 and the cavity 203 are slidably connected, allowing for pre-positioning of the device and facilitating bolt tightening. A valve body cover 4 is provided on one side of the outer wall of the first valve body 3 and the second valve body 7. A pressure plate 401 is provided on one side of the valve body cover 4, and a wear-resistant plate 402 is provided on one side of the outer wall of the pressure plate 401. Both the pressure plate 401 and the wear-resistant plate 402 have discharge holes 403 on one end of their outer walls to seal the valve body and improve the service life of the device. An intermediate housing 8 is provided between the first valve body 3 and the second valve body 7. An observation door 9 is provided on one side of the outer wall of the intermediate housing 8. The intermediate housing 8 provides the first layer of sealing, and the observation door 9 allows observation of the discharge situation inside the device. An electrical control box 6 is provided on one side of the outer wall of the first valve body 3. The electrical control box 6 is electrically connected to the cylinder 101 to facilitate the control of the valve plates inside the two valve bodies to cooperate with each other, thereby realizing double-layer airlock discharge.

[0037] Working principle: When using this device, first push the device into the designated position on the equipment. After reaching the designated position, the spring 202 returns to its original position, pushing the triangular locking block 201 out of the cavity 203 and engaging with the pre-cut slot on the equipment, thereby positioning and fixing the device on the equipment. Then, install multiple bolts onto the equipment in sequence. After the unloading device is opened, the control cylinder 101 of the electrical control box 6 drives the first valve plate 104 and the second valve plate 105 to move through the connecting assembly 102, so that the first valve plate 104 and the second valve plate 105 move through the track assembly 106, thereby opening the first valve body 3. The material enters the intermediate housing 8 through the unloading hole 403 of the valve body cover 4. After the unloading reaches the set time, the first valve body 3 will close. After closing, the second valve body 7 will be opened according to the above operation. When the first valve plate 104 and the second valve plate 105 are opened, the material in the intermediate housing 8 will be discharged through the discharge hole 403 of the pressure cap of the second valve body 7. After the discharge time is reached, the second valve body 7 will close. At this time, the airlock discharge device completes one discharge cycle. The electrical control box 6 will automatically enter the next discharge cycle according to the preset program, thereby realizing automatic discharge. The discharge time and cycle period can be set according to the actual material conditions. Since the first valve plate 104 is fixed on the second valve plate 105 by the valve plate bushing 11 and the pin, four adjusting bolts 10 are set on the second valve plate 105 to adjust the height of the first valve plate 104. The gap between the first valve plate 104 and the wear-resistant plate 402 of the pressure cap of the valve body is adjusted by the change in the height of the first valve plate 104 to ensure the airlock effect of the discharge device.
