Description

Technical Field

[0001] The utility model relates to a short-process preparation of elemental arsenic by using arsenic alkali residue, in particular to a discharging device. Background Art

[0002] In the arsenic production industry, arsenic reduction and volatilization are typically performed using pyrometallurgical reduction roasting. During this process, the raw materials are placed in a tray, undergo various processing steps, and finally, the slag in the tray is discharged. During the slag discharge process, a flip unloading system is required to quickly separate the tray from the slag.

[0003] Traditional flip unloading systems usually use cylinders to drive the material tray to rotate. The cylinders wear out a lot during use and will produce impact force on the material tray. Frequent vibration of the material tray will increase the frequency of failures and weaken the sealing performance of the entire system. There is a lot of dust during flipping, which causes great pollution to the external environment and people.

[0004] In addition, due to the instability of air pressure and the volatility of fluid, the working efficiency of the cylinder will be affected by multiple factors such as pressure and temperature, and the cylinder can only maintain a relatively low speed, resulting in low flipping efficiency. Utility Model Content

[0005] The technical problem to be solved by the utility model is that, in view of the shortcomings of the traditional overturning unloading system that uses a cylinder to drive the material tray to overturn, the utility model provides an unloading device with higher overturning efficiency and more stable performance.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A discharge device comprises a discharge chamber, wherein the discharge chamber is provided with a tray inlet, a discharge port and a tray outlet, wherein:

[0008] A tray turning space is provided in the unloading chamber, a turning tray for receiving the tray is installed in the turning space, and a clamping mechanism for clamping the turning tray and the tray into one is installed on the turning tray;

[0009] The feeding port is provided at the bottom of the tray turning space;

[0010] The middle part of the flip tray is fixedly connected to the gear shaft of the flip gear, and the flip gear is engaged with the transmission gear. The transmission gear is connected to the transmission mechanism. When the transmission mechanism drives the transmission gear, the transmission gear rotates with the flip gear and the flip tray to the unloading angle.

[0011] The utility model fixes a gear shaft connected to a flip gear in the middle of the flip tray, and the flip gear meshes with a transmission gear, which is connected to a transmission mechanism. Thus, when the transmission mechanism drives the transmission gear, the transmission gear rotates the flip gear and the flip tray together to the unloading angle. During the flipping process, due to the use of a more stable and reliable gear transmission, the utility model operates more stably and reliably, is not affected by pressure and temperature, and can maintain a certain flipping speed as needed, achieving continuous unloading.

[0012] Preferably, the transmission gear is a rack, and the transmission mechanism is a hydraulic flip rod.

One end of the baffle is hinged to the flip tray, and the other end is provided with a strip hole. The middle part of the push rod is connected to the actuating end of the cylinder, and the end of the push rod is placed in the strip hole. When the actuating end of the cylinder is extended, the push rod pushes the baffle to rotate toward the upper side of the flip tray, so that the baffle extends out of the flip tray. When the actuating end of the cylinder retracts, the push rod retracts together, and the push rod simultaneously drives the baffle to rotate toward the bottom of the flip tray. Finally, the baffle is flush with or lower than the flip tray.

[0014] Preferably, a tray lifting space is provided in the unloading chamber, a lifting pallet is installed in the tray lifting space, the lifting pallet is connected to a hydraulic lifting rod, the hydraulic lifting rod drives the lifting pallet so that the lifting pallet has a material receiving position and a transfer position, the material receiving position is docked with the tray entrance, the transfer position is docked with the unflipped flip pallet, and a hydraulic push rod is installed on the unloading chamber for pushing the tray at the transfer position onto the flip pallet.

[0026] See also Figure 1 - Figure 3 An embodiment of the unloading device of the present invention includes a hydraulic lifting rod 1, a lifting tray 2, a hydraulic push rod 3, a flip tray 4, a transmission mechanism 5, a discharge port 6, a tray outlet 7, a pneumatic clamping mechanism 8, a clamping plate 9, a blocking rod 10, a flip gear 11 and a transmission gear 12, and a unloading chamber 13.

[0027] The unloading chamber 13 is provided with a tray turning space 14 and a tray lifting space 16. The unloading chamber 13 is provided with a tray inlet 15, a discharge port 6, and a tray outlet 7. The discharge port 6 is provided at the bottom of the tray turning space 14. The tray inlet 15 is provided at the top of the tray lifting space 16, and the bottom of the tray lifting space 16 faces the tray outlet 7 provided in the tray turning space 14.

[0028] A tilting tray 4 for receiving the tray is mounted within the tray tilting space 14. A clamping mechanism is provided on the tilting tray 4 to securely fasten the tilting tray 4 to the tray. The center of the tilting tray 4 is fixedly connected to the gear shaft of a tilting gear 11. The tilting gear 11 meshes with a transmission gear 12, which is connected to a transmission mechanism 5. When the transmission mechanism 5 drives the transmission gear 12, the transmission gear 12 rotates with the tilting gear 11 and the tilting tray 4.

[0029] In this embodiment, the transmission gear 12 is a rack, and the transmission mechanism 5 is a hydraulic flip pull rod. Obviously, the transmission gear 12 of the present invention can also be a conventional gear, and the transmission mechanism 5 can be any driving mechanism that can drive the transmission gear 12.

[0030] The clamping mechanism includes a cylinder 8, a push rod 9 installed at the actuating end of the cylinder, and a baffle 10 installed at the end of the flip tray 4. One end of the baffle 10 is hinged to the flip tray 4, and the other end is provided with a strip hole. The middle part of the push rod 9 is connected to the actuating end of the cylinder 8, and the end of the push rod 9 is placed in the strip hole. When the actuating end of the cylinder is extended, the push rod 9 pushes the baffle 10 to rotate toward the upper side of the flip tray 4, so that the baffle 10 extends out of the flip tray 4 and thus prevents the material tray on the flip tray 4 from slipping during the flipping process. When the actuating end of the cylinder retracts, it retracts with the push rod 9. The push rod 9 simultaneously drives the baffle to rotate toward the bottom of the flip tray 4, and finally is flush with or lower than the flip tray 4 to avoid preventing the material tray from entering the flip tray 4.

[0031] A lifting pallet 2 is installed in the material tray lifting space 16, and the lifting pallet 2 is connected to the hydraulic lifting rod 1. The hydraulic lifting rod 1 drives the lifting pallet 2 so that the lifting pallet 2 has a material receiving position and a transfer position. The material receiving position is connected to the material tray entrance 15, and the transfer position is connected to the flip pallet 4 that has not been flipped over.

[0032] The unloading chamber 13 is also provided with a hydraulic push rod 3 for pushing the material tray at the transfer position onto the overturning tray 4 , and the pushing direction of the hydraulic push rod 3 is facing the material tray outlet 7 .

[0033] When the utility model is used, first the hydraulic lifting rod 1 pulls the lifting tray 2 to the material receiving position and faces the tray inlet 15, and then the front tray thrust (during production, the trays are discharged one by one, and the rear trays will give thrust to the front trays to prompt the trays to move forward) pushes the trays into the lifting tray 2, and then the hydraulic lifting rod 1 lowers the lifting tray 2 to the transfer position, and then the hydraulic push rod 3 pushes the trays in the lifting tray 2 into the flip tray 4, and then the clamping mechanism is activated to make the tray blocking rod 10 pop out to block the material boat on the flip tray 4, and then the hydraulic push rod 3 returns to its original position; then, the transmission The driving mechanism 5 (hydraulic flip lever) starts to operate, the transmission gear 12 rotates, and the flip gear 11 rotates accordingly, thereby pulling the flip tray 4 connected to it to the unloading angle, separating the slag from the material tray and pouring the slag into the discharge port 6. Finally, the driving mechanism 5 (hydraulic flip lever) returns to its original position, and the tray stopper 10 is retracted to its original position under the action of the clamping mechanism. The hydraulic push rod 3 is activated again to push the material tray in the flip tray 4 to the material tray outlet 7 and onto the material tray return roller. After that, the hydraulic push rod 3 returns to its original position, completing one unloading. This process is repeated to complete continuous unloading. The entire unloading process of this utility model is carried out in a fully enclosed unloading room, reducing dust emission and protecting the environment. The utility model can also achieve fully automated operation, improve production efficiency, and ensure safe production.
