Description

Feed hopper with broken function of putting up

Technical Field

The utility model belongs to the technical field of the rubbish feeding, a feeder hopper with broken function of putting up is related to.

Background

The feeding system of the garbage incineration process is mainly used for receiving and storing garbage, and the stored garbage is continuously and safely conveyed to a fire grate to be incinerated through a reciprocating mechanism. The detailed structure comprises a feed hopper, a chute and a feeder (a feed trolley and a feed platform).

The feeding hopper adopts a trapezoidal funnel type structure, receives garbage grabbed by a grab bucket of a garbage crane, and ensures that the garbage can continuously slide into a chute of the feeding channel under the action of self weight through a specific inclination angle of a front wall of the hopper. The bottom of the feed hopper is connected with the chute, the chute is of a straight pipe structure with a rectangular cross section, the size of the rectangular cross section of the chute is gradually increased from the top to the bottom to form a shape with a small top and a big bottom, and garbage slides into the chute from the feed hopper to be stored to form a material column. The feeder is arranged below the chute and surrounded by a chute lower structure and comprises a feeding trolley and a feeding platform, the garbage stored in the chute is piled up from the feeding platform, and the feeding trolley reciprocates on the feeding platform to push the garbage on the feeding platform into the incinerator.

The feeding hopper, the chute and the feeding platform are connected to form a feeding channel, and the minimum position in the whole feeding channel is the connecting position of the bottom of the feeding hopper and the chute.

The working principle of the invention is as follows:

whether a bridge exists between the feed hopper 100 and the chute 200 is judged, and two conditions exist.

Firstly, the isolation door 610 is opened, and when the low level indicator 220 detects a material signal, the feed hopper 100 is not bridged; when the low level indicator 220 detects no material and the high level indicator 123 detects material, the bridge is judged to be a bridge, which is called a bridge signal; when the low level indicator 220 detects no material and the high level indicator 123 detects no material, alarming for feeding is needed.

Secondly, the isolation door 610 is closed, and when the low level indicator 220 detects no material and the high level indicator 123 detects material, the bridge cannot be determined.

Can be simply described as: the isolation gate 610 opens a signal + the low level indicator 220 has no material signal + the high level indicator 123 has a material signal, i.e., a bridging signal. The low level indicator 220 has a material signal and the bridging signal is released.

A control method for starting a broken bridge.

First, if a bridging signal occurs, and at this time, there are a signal indicating that the bridging device 400 has retreated to the position and a signal indicating that the locking device 500 has advanced to the position, the locking device 500 needs to be first activated to unlock until the signal indicating that the locking device 500 has retreated to the position occurs.

Can be simply described as: the bridging signal + the bridge breaking device 400 retreats to the bit signal + the locking device 500 enters the bit signal, and the locking device 500 is started to unlock.

Secondly, when the locking device 500 enters the position signal and the sealing door opening signal exists, the bridging breaking device 400 starts to move downwards and inserts and extrudes the garbage at the bridging position until the bridging breaking device 400 enters the position signal, starts to retreat, and retreats to the position signal until the bridging breaking device 400 retreats, starts to advance again and again until the bridging signal is relieved.

Can be simply described as: the bridging signal, the locking device 500 retreating to the position signal and the sealing door opening signal, and the bridging breaking device 400 starts the bridge breaking until the bridging signal is removed.

Thirdly, after the bridging signal is released and the bridging breaking device 400 is withdrawn to the right position, the locking device 500 advances until the locking device 500 reaches the right position, and the surface bridging breaking device 400 is locked.

Can be described simply as: the non-bridging signal + the bridging device 400 retreats to the position signal, and the locking device 500 advances to lock the bridging device 400.

The seal separator 600 is closed requiring receipt of a lock 500 in-place signal.

In addition to automatic detection, a manually activated bridge-breaking device 400 may be provided in the event that the seal-isolating device 600 is opened.
