Description

[0001] The present invention relates to a weighing type door for refuse ingestion,

The present invention relates to an air conveyance type waste disposal system for automatically collecting household waste generated in a residential area by the air flow in a conveyance line, and more particularly, to an air conveyance type waste disposal system which measures the weight of disused waste, The present invention relates to a weighing type entrance door for a waste incineration facility.

The air conveyance type waste disposal system is a method of collecting garbage dumped into a garbage input port provided for each building layer of a residential complex through a terminal duct and a conveying duct to the collection area, The amount of waste accumulated in the end pipeline is reduced to a level lower than that of the end pipeline due to the venting action by the fan, When the valve or door is opened to a certain level, the aspiration airflow generated by the difference in air pressure causes the trash to be transferred to the collection area.

As an example of the above-mentioned air transportation type garbage disposal system, the following Patent Document 1 has an outside air suction grille and a door disposed on the front surface thereof, a body which is connected to the front end of the end pipe leading to the garbage collection pipe, And an authentication means is attached to the outside of the moving body to discriminate whether the user is an authorized user or to discriminate authenticity of the garbage bag, And the speaker is visually and audibly informed that the door provided in the body is vertically opened and closed following the forward and backward movement of the cylinder operated by the information discriminated by the authentication means or a part of the outer circumferential surface is opened with a constant width And the opening and closing of the cylindrical door formed by the inlet is rotated in the forward and reverse directions, However discloses a waste facility consisting of a commitment recognized RFID, magnetic card reader, IC card reader, or a bar code recognition method.

The following Patent Document 2 discloses an entrance door for an air conveying type waste input device having a simple structure and being easily opened and closed in accordance with the situation of the entire collection pipe, and having a structure easy to install.

Also, the following Patent Document 3 discloses an entrance door which forms a blocking wall at the entrance door to restrict the entry of only a certain amount of trash.

Korean Patent No. 10-0679223, Korean Patent No. 10-0794771, Korean Registered Utility Model No. 20-0453679,

In general, the domestic garbage collection system is implemented in such a way as to impose a cost based on the volume through the use of the trash bag of the weight-based garbage, and the amount of the garbage in the household is reduced The effect of making effort is gaining.

However, since the weight of the garbage bags to be dumped is not measured at the end but is collected at the collecting area collectively and the collection cost is imposed in the air transfer type waste disposal facility, a dispute according to the ambiguity of the cost sharing standard among each resident And this problem has been partially solved by practical application of a door having a volume limiting function as disclosed in Patent Document 3 above.

However, since the food waste is a gravimetric method, it can not be metered by the volume-limited door.

In the case of the air transfer type refuse input facility, the food garbage input port is usually provided in the kitchen of each household, but in some cases, it may be provided in the form of a joint port for use in the corridor of each floor.

Therefore, the object of the present invention is to provide a weighing type input door for an air conveying type refuse input facility capable of measuring and collecting the weight of refuse discharged through a refuse entrance door provided in a corridor of each floor .

In order to achieve the above-mentioned object, the present invention is characterized in that, on the inner surface of a hinged door mounted through a doorway in the middle of a garbage inlet, a reference wall disposed in three directions to limit the size of the garbage bag, And a slope plate attached to the bottom surface of the chute to form a space. The weight of the garbage bag placed on the chute can be measured through the load cell between the hinged door and the chute.

In the present invention, the size of the specifiable garbage bag is limited to be accommodated in the reference wall of the chute, and when the garbage bag to be dumped is placed on the chute, the weight of the load cell is measured to calculate data used for the accumulation management So that it can be particularly suitably used for measuring the weight of food waste in a waste input facility controlled by a controller so as to open a hinged door by a generation-specific authentication means.

FIG. 1 is a perspective view showing the construction of a slotting door according to the present invention; FIG.
Fig. 2 is a side sectional view of Fig. 1; Fig.
3 is a side cross-sectional view showing the state of closing the door of the entrance door.

Hereinafter, with reference to the accompanying drawings, the construction of the weighing type weighing port for the air conveying method refilling equipment according to the present invention will be described in more detail.

As shown in Fig. 1, the entrance door of the present invention is constructed such that the door 4 is attached to the middle of the garbage loading port 2 and the hinged door 6 is disposed so as to be vertically opened and closed. .

In order to limit the size of the garbage bag, the inner surface of the hinged door (6) is provided with a predetermined space by the slope plate (10) attached between the tips of the reference wall (8) And a chute 12 formed so as to be partitioned is disposed.

Inside the doorway 4, a blocking door 14 for limiting the area of the input passage is provided, and a solenoid 16 is provided on the outside of the doorway.

The solenoid 16 opens and closes the door by engaging and disengaging a normal bolt (not shown) with a bolt groove 18 formed at the upper end of the hinged door 6.

As shown in Fig. 2, the load cell 20 is interposed between the sliding door 6 and the chute 12 to measure the weight, and the inner blocking door 14 of the doorway 4 And a lower gate 24 which is pulled by a spring 22 and is always kept in a hermetically closed state is provided at the lower side of the blocking door 14 to open and close the hinge point 26 Respectively.

The food waste bag B to be dumped is opened in the direction of the arrow in the figure by opening the hinged door 6 and the chute 12 installed on the inner side of the door 6 is opened, The load cell 20 on the bottom surface measures the weight, and the signal generated at this time is input to the controller and accumulated for each generation.

That is, since the user can open the shading door 6 after generation recognition is performed by the RF card or the authentication number allocated to each generation, the weight measurement signal input from the load cell 20 to the controller each time is transmitted to the authenticated corresponding household And is integrated and processed.

Next, when the user who has inserted the food garbage bag B closes the hinged door 6, the tip end of the chute 12 interferes with the lower end gate 24 to open, as shown in Fig. 3, The food garbage bag B is dropped by sliding down the slope plate 10 while pushing the lower end of the blocking door 14 by gravity action.

In the present invention with the above-described structure, the hinged door 6 adopts a structure as disclosed in the above-described Patent Document 3, so that the hinged door 6 can be prevented from having a great deal of force in opening and closing operations.

As described above, according to the present invention, the size of a trash bag to be dumped is limited to a chute divided into a certain space, and the weight of the trash bag placed in the chute can be measured by the load cell and input to the controller. It is also advantageous to combine the capacity limitation function of the discarded garbage bag with the weight measurement function.
