[0002] Solid waste generated by people in their daily lives or in activities that provide services for their daily lives, as well as solid waste that is deemed domestic waste by laws and administrative regulations. This mainly includes residential waste, market trade and commercial waste, public place waste, street sweeping waste, and waste from enterprises and institutions. Since domestic waste contains moisture, it will increase the difficulty of incineration when burned by incineration equipment due to the influence of moisture, and at the same time increase the energy consumption of the incineration equipment. Therefore, domestic waste needs to be dehydrated before incineration, so domestic waste dehydration equipment is used.

[0003] However, when domestic garbage is dehydrated using a dehydration device, the staff needs to put the domestic garbage to be dehydrated into the interior of the dehydration device, wait for the domestic garbage to be dehydrated before taking the domestic garbage out from the interior of the dehydration device. When the dehydration device adopts a side door opening method, domestic garbage accumulates inside the dehydration device. When the sealed door is opened, the domestic garbage will fall from the interior of the dehydration device without the obstruction of the sealed door, which brings inconvenience to the staff in cleaning up the domestic garbage after dehydration. When the dehydration device adopts a top door opening method, when the staff cleans the domestic garbage in the device, they need to extend their arms into the interior of the device to take out the domestic garbage at the bottom. Since the dehydration device has a certain height, the way the staff reach into the interior of the device also brings inconvenience to the cleaning of the domestic garbage after dehydration.

[0037] Working principle: When in use, first, the box cover 21 is in the open state, and the domestic garbage to be dehydrated is loaded into the interior of the cylinder 1. Since the cylinder 1 and the cylinder cover 15 are connected in a threaded sleeve manner, and the external thread 11 and the internal thread 16 are matched, the cylinder cover 15 is installed on the upper end of the cylinder 1 in a rotating manner. At this time, the pressure plate 2 is located above the domestic garbage stored in the cylinder 1. Then the cylinder 1 is placed on the No. 1 multi-stage hydraulic cylinder 3. At this time, the protrusion 18 is clamped in the inside of the groove 12, and the No. 1 multi-stage hydraulic cylinder 3 is opened. Power supply, after the No. 1 multi-stage hydraulic cylinder 3 is turned on, it drives the retraction of its internal output shaft, and moves the cylinder 1 to the inside of the box 4 until the bottom of the cylinder 1 is placed on the support plate 26. At this time, the round rod 27 is sleeved inside the cylindrical groove 13. After the output shaft of the No. 1 multi-stage hydraulic cylinder 3 is completely retracted, the groove 12 is separated from the protrusion 18, and the cylinder 1 is fixed on the support plate 26. Then, the power supply of the electric push rod 10 is turned on. After the electric push rod 10 is turned on, it drives the telescopic movement of its internal output shaft until the splint 8 is sleeved on the outside of the annular block 7. At this time, the ball 9 is against the outer wall of the annular block 7, and the power of the driving motor 25 is turned on. After the driving motor 25 is turned on, the driving gear 501 is driven to rotate through the connection of the rotating shaft 24. Due to the tooth meshing connection between the driving gear 501 and the driven gear 502, the driving gear 501 rotates while driving the driven gear 502. The rotation of the driven gear 502 drives the rotation of the cylinder 1 through the cooperation of the round rod 27 and the support plate 26. The rotation of the cylinder 1 can dehydrate the domestic waste inside. After the dehydration is completed, turn on the power of the No. 2 multi-stage hydraulic cylinder 14 to squeeze the domestic garbage inside the cylinder 1 to improve the dehydration effect of the domestic garbage. Finally, take the cylinder 1 out from the inside of the box 4, open the box cover 21, turn on the power of the electric push rod 10 and the power of the No. 1 multi-stage hydraulic cylinder 3, open the electric push rod 10 to separate the splint 8 from the cylinder 1, open the No. 1 multi-stage hydraulic cylinder 3 to insert the protrusion 18 into the inside of the groove 12, and then push the cylinder 1 out from the inside of the box 4 to clean the domestic garbage inside the cylinder 1.
