The compressed air pipeline 1.26 is respectively connected with the air curtain 1.22 of the airtight door and the air curtain of the warehouse airtight door 2.22. Under the control of 1.26B, the compressed air is respectively transported to the air curtain 1.22 of the airtight door and the air curtain 2.22 of the airtight door of the warehouse through the compressed air pipeline 1.26,

Geomagnetic induction coils 1.24A, 1.24B and 1.24C are also arranged on the ground of the dumping room 1.1, and the geomagnetic induction coils 1.24A, 1.24B and 1.24C are used to collect the position signal of the dumping truck 3; Travel control switches 1.25A and 1.25B are also set on 1.22 and the air curtain 2.22 of the airtight door of the warehouse, respectively. The travel control switches 1.25A and 1.25B are used to obtain the position signal of the opening of the airtight door 1.21 and the airtight door of the warehouse 2.21 respectively.

An automatic control system is also provided. The automatic control system controls and collects the signals of the dump truck 3 through the geomagnetic induction coil, and controls the airtight door 1.21, the air curtain 1.22 of the airtight door and the bin airtight door through the travel control switch. 2.21. Opening or closing of the air curtain 2.22 of the airtight door of the warehouse. At least one door of the room airtight door and the bin airtight door is closed at any time.

As shown in FIG. 1, in this example, a door hole 1.21A is also provided at the lower part of the compartment airtight door 1.21, and a door hole 2.21A is also provided at the lower part of the compartment airtight door 2.21, and the door hole 1.21A , 2.21A are respectively provided with an inter-breathing valve 1.21B, a warehouse breathing valve 2.21B, the breathing valve is used to open or close the door hole.

Figure 1 shows that, in this example, the air pressure in the unloading room 1.1 is greater than the air pressure in the unloading bin 2.1.

As shown in Figure 1, in this example, the inter-breathing valve 1.21B or the silo breathing valve 2.21B is a plate-shaped ventilation check valve, and the air can only enter the unloading room 1.1 from the outside in one direction or from the The unloading room 1.1 enters the unloading bin 2.1.

As shown in FIG. 1 , in this example, the deodorization and ventilation system suction pipes 1.23 are arranged in the upper part of the sludge discharge room 1.1 and its suction ports 1.23A are multiple and extend to various positions.

Since the air pressure in the unloading room 1.1 is in a negative pressure state, there is a pressure difference between the inside and outside of the breathing valve plate 1.21B2, and the external air pressure is greater than the internal air pressure in the unloading room 1.1. The gas enters the unloading room 1.1 from the closed door hole 1.21A of the room to realize ventilation.

In this example, the opening degree of the breathing valve plate 1.21B2 will change with the change of the internal air pressure of the mud unloading room 1.1 so that the said unloading room maintains a constant negative pressure.

The present invention also provides an automatic control system. During the operation, when the sludge dump truck 3 reverses and passes through the geomagnetic induction coil 1.24A, the signal is sent to the automatic control system, and the automatic control system controls the closed door 1.21 of the room to open. 1.25A, the signal is sent to the automatic control system, and the automatic control system controls the solenoid valve 1.26A to open. At this time, the air curtain 1.22 of the airtight door in the unloading room will continue to spray gas, so that the odor in the unloading room 1.1 cannot escape to the outside.

Sludge unloader 3 continues to reverse into the unloading room, the geomagnetic induction coil 1.24B is triggered, and the signal is sent to the automatic control system. The local magnetic induction coil 1.24A or 1.24B has a continuous signal sent to the automatic control system. At this time, the door is closed at 1.21 The air curtain 1.22 is in the open state. When the sludge dump truck 3 reverses and crosses the geomagnetic induction coil 1.24B, the signals of the geomagnetic induction coils 1.24A and 1.24B disappear, and the airtight door 1.21 and the air curtain 1.22 are closed.

The sludge dump truck 3 reverses to the parking position. The geomagnetic induction coil 1.24C detects the sludge dump truck, and the signal will be sent to the automatic control system. The automatic control system controls the bin closed door 2.21 to open. When it is opened to a certain degree of opening , trigger the stroke control switch 1.25B, the signal is sent to the automatic control system, the automatic control system controls the electromagnetic control valve 1.26B to open, at this time, the air curtain 2.21 of the airtight silo will continue to spray gas, and the odor in the unloading silo 2.1 cannot escape to In the unloading room 1.1.

When the sludge unloading truck 3 completes the unloading operation, in the process of driving away, first the signal of the geomagnetic induction coil 1.24C disappears, and the silo airtight door 2.21 and the silo air curtain 2.22 are closed. When the sludge dump truck 3 enters the position of the geomagnetic induction coil 1.24B, the signal will be sent to the automatic control system again, and the airtight door 1.21 and the air curtain 1.22 will be opened. When the sludge unloading truck 3 completely leaves the unloading room 1.1 and the geomagnetic induction coil 1.24A cannot detect the signal, the airtight door 1.21 and the air curtain 1.22 will be closed. At this time, the airtight door 1.21 and the air curtain 1.22 and the airtight door 2.21 of the warehouse and the air curtain 2.22 are all closed at the same time.

No matter when the unloading truck 3 is driving in or leaving, the intermediate deodorizing system 1.2 and the silo deodorizing system 2.2 are both in the suction state, so that the unloading room and the unloading silo maintain negative pressure, and maintain the negative pressure during the unloading process. pressure operating requirements. By setting up two sets of fast airtight doors and airtight door air curtains, and optimizing the configuration of an automatic control system with two airtight deodorizing barriers, the automatic control of the sludge unloading process, the classification and isolation of odors and the classification of odors can be effectively realized.

In addition, door holes 1.21A and 2.21A are respectively provided at the lower part of the airtight door 1.21 and the compartment airtight door 2.21, and the door holes 1.21A and 2.21A are respectively provided with an inter-breathing valve 1.21B and a compartment breathing valve.
