Air energy heat pump technology is an emerging heat pump technology that has been widely used in air conditioning, heating and hot water. It has the advantages of high efficiency, environmental protection and energy saving, and is suitable for the recycling of waste heat and waste cold.

[0015] In order to solve the problem that the existing sludge drying equipment is difficult to be widely used due to its large floor space, long processing cycle and great influence of weather changes, the present invention can save energy and improve energy efficiency through an air energy heating mechanism. Since the heat pump can recover the heat in the drying exhaust gas and utilize low-temperature drying conditions, the energy consumption level in the drying process can be effectively reduced. At the same time, it is less affected by the external environment temperature and humidity and has strong regional adaptability.

[0016] The air energy heating mechanism can reduce pollution and improve environmental protection. Since the low temperature drying condition below 100°C can avoid the volatilization of odorous organic matter, and the closed hot air circulation can also significantly reduce the overflow of circulating air in the system, it is generally unnecessary to treat tail gas and wastewater.

[0017] Through the air energy heating mechanism, the organic matter of the sludge can be maintained and resource utilization can be improved. Since the temperature is not high during the sludge drying process, the loss of organic matter is small and the utilization potential is large.

[0018] The air energy heating mechanism can improve the safety of the system and reduce risks. The operating environment temperature is not high during the sludge drying process, and dust can be avoided under the condition of reasonable control of wind speed. The heat pump sludge drying system can fully meet the safety requirements of sludge drying, thereby greatly improving the safety of system operation.

[0019] In order to further improve the practicability and the applicability, the present invention proposes an anti-clogging sludge turning mechanism, and the sludge is dried more evenly through the sludge drying ventilation component.

[0020] The scraper can clean the inner wall of the drying drum to prevent the sludge from sticking to the inner wall of the drying drum after drying.

[0021] The setting of the partition increases the contact area between the sludge and the drum wall and improves the heat transfer efficiency.

[0022] The function of the filter cotton is to filter the air when it is first supplied.

[0023] The setting of the jet hole can flush the loose sludge out of the hexagonal ventilation hole.

[0024] During the rotation of the partition, the magnetic block 1 slides back and forth on the slide rod when there is no blockage. When the long edge vent is blocked, the magnetic block 1 moves to the upper end, and the magnetic block 1 and the magnetic block 2 repel each other, thereby pushing the shovel blade 2 to clear the sludge.

[0048] When in use, first open the door 8, transport the sludge to be dried to the drying drum 7, close the door 8, start the compressor 38, extract air from the filter chamber 45, and after being filtered by the filter cotton 46, enter the compressor 38 to compress the refrigerant from a low-temperature and low-pressure state to a high-temperature and high-pressure state. The refrigerant passes through the condenser 39 through the air circulation pipe 42, transfers heat to the air, and becomes liquid at the same time. After the air is heated, it is sent into the power chamber 15 through the fan 43, enters the drying drum 7 through the power chamber 15, contacts the sludge, transfers heat to the sludge, and evaporates its moisture. After the humid hot air comes out of the drying drum 7, it enters the evaporator 40, exchanges heat with the refrigerant, is cooled and dehumidified, and at the same time vaporizes the refrigerant. The refrigerant passes through the evaporator 40. After that, it becomes gaseous and re-enters compressor 38 to complete the cycle. After the refrigerant becomes liquid, it will pass through expansion valve 41 and then enter evaporator 40 to become gaseous again. After being heated, the air will pass through fan 43 and then enter drying drum 7 to contact with sludge. In order to make the sludge dry more evenly, the output end of motor 16 rotates to drive drive shaft 58 to rotate, the drive shaft 58 rotates to drive bevel gear 17 to rotate, the bevel gear 17 rotates to drive bevel gear 2 18 to rotate, the bevel gear 2 18 rotates to drive pipe 19 to rotate, the drive pipe 19 rotates to drive partition 24 to rotate, the partition 24 rotates to drive the digging block 28 to rotate, and the sludge is rolled, the output end of motor 2 53 rotates to drive gear 3 54 to rotate, the gear 3 54 rotates to drive gear ring 55 to rotate, The rotation of the gear ring 55 drives the drying drum 7 to rotate. The rotation direction of the drying drum 7 is opposite to that of the partition 24. The scraper 29 can clean the inner wall of the drying drum 7 to prevent the sludge from being dipped on the inner wall of the drying drum 7 after drying. The hot gas can pass through the hexagonal air vents 26 and the long-edge air vents 27. The setting of the partition 24 increases the contact area between the sludge and the drum wall and improves the heat transfer efficiency. In order to prevent the hexagonal air vents 26 from being blocked, the air pump 22 is started to pass the air flow through the vent pipe 23 into the drive pipe 19, and enter the ventilation cavity 25 through the vent 1 20, and is ejected through the jet hole 30 to flush the loose sludge out of the hexagonal air vent 26. During the rotation of the partition 24, the magnetic block 3 60 slides back and forth on the slide bar 2 59 without being blocked. When the hexagonal vent 26 is blocked, when the magnet block 3 60 moves to the upper end, the magnet block 3 60 and the magnet block 2 33 repel each other, thereby pushing the scraper 3 61 to clear the sludge in the hexagonal vent 26. During the rotation of the partition 24, the magnet block 1 32 slides back and forth on the slide bar 31 without being blocked. When the long-edge vent 27 is blocked, when the magnet block 1 32 moves to the upper end, the magnet block 1 32 and the magnet block 2 33 repel each other, thereby pushing the scraper 2 35 to clear the sludge. The function of the filter cotton 46 is to filter the air during the initial air supply. The present invention produces a dry environment by heating the air and making it flow through the sludge. In such an environment, the moisture in the sludge will gradually migrate to the sludge surface and evaporate, and by controlling the drying time, temperature and air flow rate,The drying degree can be effectively adjusted to evaporate the water in the sludge as much as possible. The above is the overall working process of the present invention. Repeat this step next time you use it.
