Description

A PROTECTION SYSTEM FOR SECURE OPERATION OF REFUSE COLLECTION EQUIPMENT}

The automatic garbage collection facility has excellent economic and environmental efficiency and is installed in a large area rather than a small area. However, as the number of inputs is increased and the collection pipe distance is increased, the collection pressure increases as the waste collection in a large area is increased.

In order to collect a large amount of waste at a long distance, a large amount of air flow and a high collection pressure using a blower are used. If the waste inlet user or system configuration equipment is exposed to such a high air flow and pressure, it may lead to safety accidents and damage to the equipment. have.

Accordingly, the present invention is to provide a system for the automatic collection of trash for the safety and system protection of the user in a large trash automatic collecting facility with a large number of garbage input or long suction pipe distance.

Garbage collection facility is a technology that collects the wastes that are put in the distant places of the complex using a blower and a conveying line. However, when installing garbage dumps, the installation cost is high, and the residents are disliked to come near my house, so the collection facilities are getting larger.

Collecting garbage in a wider area by installing a single dump can reduce the cost of installing a dump, which is economically advantageous and environmentally advantageous by reducing the frequency of operation of the truck from the dump to the final disposal site.

In this case, however, the number of garbage outlets and the garbage collection distance is increased, and domestic food waste is very high in proportion to foreign food waste, so the blower that generates the waste collection pressure must be enlarged.

In order to collect garbage from many remote waste inlets, high collection pressures must be used from the design stage. Therefore, the use of such a large amount of airflow and collection pressure requires attention for user safety and system protection.

If the blower is operated above the specified collection pressure due to the interference of external signals while the automatic garbage collection facility is operating, or sudden blockage occurs while the garbage is being collected through the delivery line, and the automatic speed control system is temporarily operated normally. If not, the following phenomenon may occur.

1. Noise generated by excessive collection pressure may cause people near the input to be surprised or exposed to high frequency noise.

2. Excessive collection pressure may cause deformation of some of the inlets. Inlet, section valve, air intake valve, etc. are precision products with no leakage. If deformation occurs, expensive equipment should be replaced.

3. If there is a user collecting waste into the inlet while excessive collection pressure is created and the discharge valve is open, hand pinching may occur and people may be sucked into the opening such as the inlet.

In addition, the following phenomenon may occur in the case of the collection.

1. The entire deformation of the blower occurs.

2. Deformation of the container body occurs.

3. Compressor body deformation or leakage protection may be damaged.

4. May cause damage to other valves.

To solve this problem, automatic waste collection facilities need a protection system from system overload.

The present invention requires a high collection pressure in order to collect waste in a large area with a lot of input holes, and at this time, the purpose of ensuring the safety of the users of the waste input port and residents near the input port, and to prevent the deformation of equipment due to high collection pressure.

The above-mentioned objects, features and advantages will become more apparent from the following detailed description in conjunction with the accompanying drawings.

Figure 1 is a schematic diagram showing the waste inlet and the waste transport passage of the automatic waste collection facility of the present invention, Figure 2 is a schematic diagram showing a facility connected to the automatic switching valve 300 of FIG.

Referring to FIG. 1, a plurality of garbage inlets 10 through which users input waste are shown, and a waste transport pipe 50 buried underground is shown. The conveying pipe 50 is applied with the waste suction conveyance force by the blower 150 of Figure 2, there is an air intake valve 20 for sucking the air to add force to the waste conveyance.

The section valve 40 is a section valve (section valve) for each section in consideration of the fact that if the suction conveying all of the waste conveying pipe 50 of many sections at the same time may go to the blower 150 or blockage in the conveying pipe 50 Put the 40 to sequentially open the section valve 40 to transfer the waste of the transfer pipe (50).

The waste discharged to the lower end of the waste inlet 10 is transported through the transfer pipe 50 according to the opening of the corresponding section valve 40 and separated and transferred to general waste and food waste through the automatic switching valve 70. 2 each of the centrifuges 80, 110. Air flow rate control valves (85, 115) are installed on the top of each centrifuge (80, 110).

In the case of general waste, the waste is conveyed to the waste container conveying apparatus 100 through the general waste centrifuge 80 and the general waste compressor 90 and finally transported by vehicle.

Meanwhile, the food waste is stored in the food waste storage tank 130 through the food waste centrifuge 110 and the foreign matter separator 120 and is taken out through the food waste transport facility.

The above-mentioned waste conveying system is provided with a blowing facility for moving to the waste container conveying apparatus 100 or the food waste storage tank 130 for the purpose of the waste entered into the waste conveying line. 2, two blowers 150 are shown connected to the waste conveying line. The blower 150 uses a large capacity in order to provide a strong garbage collection power in the case of a large system, it is generally used by connecting several. The operation of the large-sized blower 150 is expected to transfer the waste quickly, when the waste moving the transfer pipe 50 is blocked in the transfer pipe 50 on the way, the transfer pipe 50 by the continuous operation of the blower 150 ) Within the collection force is higher than normal, this may cause a dangerous situation, such as the user's hand is carried into the garbage inlet 10, the connected expensive equipment may be damaged by the collection force. Therefore, in order to solve the above problems, the present invention provides a safety valve 160 on the conveying pipe 50 near the blower 150 to generate a negative pressure lower than normal in the conveying pipe 50. In this case, the safety valve 160 is opened so that air is introduced into the conveying pipe 50 so as not to be overloaded in the conveying pipe 50.

Detailed operation of the safety valve 160 will be described with reference to FIG.

The safety valve 160 installed vertically from the conveying line 50 is engaged with the air inlet 163 and the air inlet 163 in the form of a hole through which external air can be introduced when the air inlet 163 is closed. And an air inlet opening and closing portion 164 that is separated below the air inlet 163 to open the air inlet 163, and the air inlet opening and closing portion 164 is fixed to the shaft 161 and the shaft 161. ) Is connected to the upper end of the spring fixing top plate 165 and interlocked up and down. The upper portion of the spring 162 is fixed to the spring fixing upper plate, and the lower portion of the spring 162 is fixed to the spring fixing lower plate 166.

If the internal pressure of the conveying pipe 50 is normal, such as when the waste passes smoothly through the conveying pipe 50 or the blower 150 does not operate, the spring 162 of the safety valve 160 is in a normal state of the spring. Therefore, the air inlet opening and closing part 164 is engaged with the air inlet 163 to prevent the air from flowing into the air inlet 163. However, when the transport pipe 50 is blocked by the waste, since the excessive amount of negative pressure is generated in the transport pipe 50 after the blockage is caused by the continuous operation of the blower 150, the air inlet connected to the spring 162 accordingly. The opening and closing portion 164 is lowered by the action of negative pressure and gravity to open the air inlet 162 to allow air to flow from the outside.

At this time, the shaft 161 on which the air inlet opening and closing portion 164 is fixed and the spring fixing top plate 165 are lowered together, so that the spring 162 is compressed and the opening of the air inlet 162 is transferred to the delivery pipe 50. When the excessive negative pressure inside is restored to normal, the spring 162 is also relaxed again and returns to the normal state, thereby closing the air inlet 163 due to the rise of the air inlet opening and closing unit 164.

The blower air suction valve 170 operates in conjunction with the speed measuring device 180 of FIG. That is, the speed measuring device 180 measures the air flow rate in the conveying pipe 50 by using a venturi device, and detects an abnormal speed when the air conveying speed becomes faster than the normal speed due to excessive sound pressure generation. To transmit a signal to the blower air intake valve (170). The blower air intake valve 170 receiving the signal thereby removes the excessive sound pressure in the transfer pipe 50 by introducing external air.

The blower air intake valve 170 has a cross-sectional structure in FIG.

Like the safety valve 160, the blower air intake valve 170 is also installed perpendicular to the transport pipe 50, and an air inlet 171 having a hole shape for introducing air into the transport pipe 50 is disposed on the pipe. And a valve disc 172 opening and closing the air inlet 171 is seated in the air inlet 171, and an upper end of the valve disc 172 is connected to a cylinder rod 173, and the cylinder rod 173 The top is connected to the drive cylinder 174. As described above, when the speed measuring device receives a signal according to the measurement of the abnormal speed of the air too fast, the drive cylinder 174 is operated to lift the cylinder rod 173 and the valve disk 172 to lift the valve disk 172. The air inlet 171, which was closed by), is opened, and external air is sucked into the delivery pipe 50 so that the excessively formed negative pressure in the pipe returns to a normal state.

The above-described blower air intake valve 170 is provided with a soundproofing agent 175 on its outer wall to prevent the noise caused by the operation of the blower 150 is spread. In order to shield the noise caused by the operation of the blower 150, the silencer 150 is adopted on the system (see FIG. 1).

In addition, the blower air suction valve 170 may be installed on the top of the centrifuge (85, 110).
