Description

Technical Field

[0001] This utility model relates to a small-package waste feeding mechanism for a rotary kiln feeding system. Background Technology

[0002] In hazardous waste incineration systems, highly reactive, corrosive, flammable, or toxic wastes need to be packaged into smaller packages and fed separately through the small-package feeding mechanism of the hazardous waste feeding system. A traditional hazardous waste feeding system consists of a hopper located in front of the rotary kiln's feed gate, a solid waste feed hopper above the hopper, and a pusher rod in front of the hopper. A square small-package waste inlet is opened on one side wall of the hopper, and a side door is installed on the outside of the small-package waste inlet for sealing. A feeding platform and a small pusher rod are sequentially located outside the side door; the small-package waste on the feeding platform is pushed into the hopper by the small pusher rod.

[0003] Traditional hazardous waste feeding systems have the following problems:

[0004] 1. Leakage in the sealing gap: The side door opens downwards, so the material feeding platform and the side wall of the hopper need to have a gap of at least the thickness of the side door. This gap will cause small packaged waste materials to get stuck when feeding, and solid waste in the hopper to leak and fall.

[0005] 2. Environmental pollution: Solid waste leakage from the silo will pollute the work area, thus increasing cleanup costs;

[0006] 3. Equipment failure: Leaking material corrodes the limit switch of the side door, causing the side door to close and affecting the continuity of the incineration system. Utility Model Content

[0007] The purpose of this utility model is to overcome the defects of the prior art and provide a small packaged waste feeding mechanism for a rotary kiln feeding system. It can avoid the material jamming phenomenon caused by the gap of the hopper side door and reduce the leakage of sludge in the hopper through the gap, thus reducing environmental pollution.

[0008] The purpose of this utility model is achieved as follows: a small-package waste feeding mechanism for a rotary kiln feeding system. The rotary kiln feeding system includes a rotary kiln, a feeding channel connected to the rear feed inlet of the rotary kiln, a hopper connected to the rear end of the feeding channel, a solid waste feeding hopper located above the hopper, a pusher cylinder connected to the rear wall of the hopper, and a pusher rod installed inside the pusher cylinder. The small-package waste feeding mechanism includes a small-package waste feed inlet located at the lower part of one side wall of the hopper, a hopper side door installed outside the small-package waste feed inlet, and a feeding platform installed outside the hopper side door at the same height as the bottom plate of the hopper. The small-package waste feeding mechanism also includes a grid, a sludge guide trough, and a sludge collection bucket.

[0009] The silo side door opens upwards via a hydraulic lifting mechanism to open the small packaged waste inlet, and closes downwards via the same mechanism.

[0010] The grille is connected between the inner end of the feeding platform and the side of the bottom plate of the hopper;

[0011] The mud guide channel is connected to the bottom surface of the grid;

[0012] The sludge collection bucket is located on the ground below the sludge guide channel.

[0013] The small packaged waste feeding mechanism of the rotary kiln feeding system described above, wherein the mud guide trough includes an inverted V-shaped guide cylinder connected at the upper end to the bottom surface of the grid and a straight cylindrical diversion cylinder connected at the lower end of the guide cylinder.

[0014] The small packaged waste feeding mechanism of the rotary kiln feeding system described above includes a feeding gate at the front feed inlet of the rotary kiln.

[0015] The small package waste feeding mechanism of the rotary kiln feeding system described above further includes an elevator and a small push rod; the elevator is installed on the ground outside the feeding platform; the small push rod is located at the same height as the feeding platform outside the elevator.

[0016] The features of the small-package waste feeding mechanism of the rotary kiln feeding system of this utility model are:

[0017] 1. By changing the side door of the hopper from moving downwards to opening the small packaged waste inlet to moving upwards, and by installing a grid between the inner end of the feeding platform and the small packaged waste inlet on the side wall of the hopper, the gap between the feeding platform and the side wall of the hopper is eliminated, thus avoiding the jamming phenomenon caused by the gap.

[0018] 2. By adding a mud guide trough to the bottom of the grid and installing a sludge collection bucket below the mud guide trough, the sludge flowing out of the small packaged waste material inlet of the silo can be collected, reducing sludge leakage and pollution of the work area.

[0020] Figure 2 yes Figure 1 View A in the diagram. Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] Please see Figure 1 and Figure 2 The present invention relates to a small packaged waste feeding mechanism for a rotary kiln feeding system. The rotary kiln feeding system includes a feeding channel 11 connected to the rear feed inlet of the rotary kiln 1, a hopper 2 connected to the rear end of the feeding channel 11, a solid waste feeding hopper 3 located above the hopper 2, a pusher cylinder 12 connected to the rear wall of the hopper 2, and a pusher rod 4 installed inside the pusher cylinder 12. A feeding gate 10 is installed at the rear feed inlet of the rotary kiln 1, and the feeding gate 10 is hydraulically driven to open and close.

[0023] The small package waste feeding mechanism includes a small package waste inlet located at the lower part of one side wall of the silo 2, and a silo side door 20 installed on the outside of the small package waste inlet. The silo side door 20 opens the small package waste inlet upward through a hydraulic lifting mechanism 5, and closes the small package waste inlet downward through the hydraulic lifting mechanism 5.

[0024] The small package waste feeding mechanism also includes a feeding platform 6 installed on the outside of the hopper side door 20 and at the same height as the bottom plate of the hopper 2, an elevator 6A located on the ground outside the feeding platform 6, and a small push rod 6B located on the outside of the elevator 6A and at the same height as the feeding platform 6; the small push rod 6B is also hydraulically driven.

[0025] The small-package waste feeding mechanism also includes a grid 7, a sludge guide trough 8, and a sludge collection bucket 9, among which...

[0026] The grating 7 is connected between the inner end of the loading platform 6 and the side of the bottom plate of the hopper 2;

[0027] The mud guide trough 8 is installed on the bottom surface of the grid 7; the mud guide trough 8 includes an inverted V-shaped guide cylinder connected to the bottom surface of the grid 7 at its upper end and a straight cylindrical diversion cylinder connected to the lower end of the guide cylinder.

[0028] The sludge collection bucket 9 is located on the ground below the sludge guide channel 8.

[0029] The small-packaged waste feeding mechanism of the rotary kiln feeding system of this utility model uses a grab bucket to feed solid waste from the solid waste feed hopper 3 into the lower hopper 2. Then, the push plate at the front end of the push rod 4 pushes the waste in the hopper 2 forward into the feed inlet of the rotary kiln 1. When there is a need for incineration of small-packaged waste, it is transferred to the elevator 6A. When the elevator 6A lifts the small-packaged waste to the same height as the feeding platform 6, the hopper side door 20 opens the small-packaged waste feed inlet upward through the hydraulic lifting mechanism 5. At this time, the small push rod 6B pushes the small-packaged waste into the hopper 2 sequentially from the feeding platform 6, the grid 7, and the small-packaged waste feed inlet. Afterward, the small push rod 6B retracts, and the hopper side door 20 closes the small-packaged waste feed inlet downward through the hydraulic lifting mechanism 5. Because solid waste and small packaged waste are alternately fed into silo 2, the sludge in the residual solid waste in silo 2 will flow out through the small packaged waste inlet when the silo side door 20 is opened. The sludge will flow onto the grid 7 immediately and then into the sludge collection bucket 9 below the sludge guide trough 8 at the bottom of the grid 7, reducing the spread of sludge to the feeding platform 6. After the silo side door 20 is closed, the push rod 4 will push the waste in silo 2 into the rotary kiln 1 after the feed door 10 is opened.

[0030] The above embodiments are for illustrative purposes only and are not intended to limit the present invention. Those skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention and should be defined by the claims.
