Description

Technical Field

[0001] The utility model relates to the field of design and use of a batching bin, and specifically refers to a remote safety control structure for preventing and controlling material leakage from a sintering batching bin. Background Art

[0002] Raw materials with extremely high water content enter the batching bin of the sintering workshop. During the sintering batching process, material leakage becomes the norm, which seriously threatens the safety of sintering production. When the moisture content of the material is high, the mineral powder mainly leaks out from the disc discharge port.

[0003] Many places will add a valve body at the outlet to compensate for the above problems, but the valve body needs to be opened manually, which is very troublesome to operate and also requires a lot of man-hours. Utility Model Content

[0004] The technical problem to be solved by the utility model is

[0005] In order to solve the above problems, the technical solution adopted by the present invention is as follows: The present invention is a remote safety control structure for preventing and controlling material leakage from a sintering batching bin, comprising a disc hopper, a disc bottom trough and a controller, wherein the disc bottom trough is connected to the bottom of the disc hopper, and the controller is arranged on the disc hopper. The controller comprises a motor, a runner, a plug valve and a traction rope, wherein the motor is arranged on the disc hopper, the runner is installed on the output shaft of the motor, the plug valve slides through the top wall of the disc bottom trough and blocks the discharge port of the disc bottom trough, and the traction rope is arranged between the plug valve and the runner.

[0006] Furthermore, a lining plate is provided in the bottom groove of the disc.

[0007] Furthermore, the motor is a forward and reverse rotating motor, and the motor controls the rotation of the wheel.

[0008] Furthermore, the motor is a 1.5KW motor.

[0009] The beneficial effects achieved by the utility model using the above structure are as follows: This design ensures the safety of batching during the rainy season production process by installing a safety method that combines an anti-leakage gate and a remote safety control electric valve. If there are signs of leakage, the electric gate can be remotely controlled to be lowered. At the same time, in conjunction with the anti-leakage gate, the mineral powder discharge process can be ensured. Personnel can remotely control the downward movement of the safety gate to ensure the safety of batching workers or patrol workers, and prevent the expansion of leakage.

[0015] As the instruction manual Figure 1 As shown, the utility model is a remote safety control structure for preventing and controlling material leakage from a sintering batching bin, comprising a disc hopper 1, a disc bottom trough 2 and a controller 3. The disc bottom trough 2 is connected to the bottom of the disc hopper 1, and the controller 3 is arranged on the disc hopper 1. The controller 3 comprises a motor 4, a runner 5, a plug valve 6 and a traction rope 7. The motor 4 is arranged on the disc hopper 1, and the runner 5 is installed on the output shaft of the motor 4. The plug valve 6 slides through the top wall of the disc bottom trough 2 and blocks the discharge port of the disc bottom trough 2. The traction rope 7 is arranged between the plug valve 6 and the runner 5.

[0016] A lining plate (not shown) is provided in the bottom groove 2 of the disc. The motor 4 is a forward and reverse rotating motor, and the motor 4 controls the rotation of the runner 5. The motor 4 is a 1.5KW motor.

[0017] As the instruction manual Figures 2 to 4 As shown, the drive unit is a 1.5kW motor, model YE4-90L-4, controlled by contactors. KRC and KAC are the up and down contactors, respectively. SS is the stop button. SF and SR are the up and down start buttons, respectively, on the machine's side operating box. SLS is the local / remote control switch. When moved to the left, it is controlled by local buttons, while when moved to the right, it is controlled by a remote controller. K1 to K6 are relay contacts inside the receiver, connected to the control circuits of the electro-hydraulic gate valves in warehouses 1# to 3#, respectively. This allows simultaneous control of three groups.

[0018] When in use: the motor 4 drives the wheel 5 to rotate, and the traction rope 7 pulls the gate valve 6 upward to control the opening.

[0019] Regarding electrical control, during normal production, the conversion switch on the electro-hydraulic plug valve control box is turned to the local position, and the SF and SR buttons are used to control the rise and fall of the plug valve 6.

[0020] When there is a risk of warehouse leakage during production in the rainy season, turn the conversion switch on the control box of the electro-hydraulic plug valve 6 to the remote control position, operate through the remote control, press the start button of the remote control to close the power, and then use the remaining 6 buttons on the remote control to control the lifting of the 1#~3# warehouse gates. Among them, the up and down buttons respectively control the lifting of the 1# warehouse gate, the left and right buttons respectively control the lifting of the 2# warehouse gate, and the front and rear buttons respectively control the lifting of the 3# warehouse gate. Remote control operation can avoid the safety risk of warehouse leakage when operating at the local machine and ensure personal safety.

[0021] It should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
