Description

Technical Field

[0001] The utility model belongs to the technical field of rotary wheel dehumidification units, and particularly relates to a regeneration heat insulation device for a rotary wheel dehumidification unit. Background Art

[0002] The rotary wheel dehumidifier belongs to an important branch in the air conditioning field and is a typical representative of temperature-controlled dehumidification. The main production areas of global rotary wheel dehumidifiers are concentrated in the United States, Japan, Sweden, China and other places. Rotary wheel dehumidifiers in China have also been developed for more than 20 years. With the industrial upgrading in China, the demand for rotary wheel dehumidifiers has increased sharply, and Chinese rotary wheel dehumidifier enterprises have also achieved great development and have gradually been recognized by Chinese consumers. At the same time, in terms of the composition of the rotary wheel, before 2008, it had developed to the fourth generation: silica gel, and the most advanced was the molecular sieve + silica gel structure.

[0003] In the prior art, a rotary wheel dehumidification unit and a regeneration heat insulation device for a rotary wheel dehumidification unit with the patent publication number of CN202336283U includes: an outer frame body, and a plurality of horizontally arranged blades (11) are arranged in the outer frame body. The blade shafts (12) of the blades (11) are connected by electric levers, and the electric head drives each blade (11) to rotate synchronously through the electric lever. For the rotary wheel dehumidification unit and the regeneration heat insulation device for the rotary wheel dehumidification unit of the utility model, a high-temperature heat insulation device is installed at the regeneration part of the rotary wheel dehumidification unit, and the structure is simple.

[0025] Further, as shown in Figure 1 、 Figure 2 and Figure 3 it is worth specifically stating that a supply air fan 15 is fixedly connected to the front directly below the inner surface bottom of the supply air chamber C, and a backup power supply 16 is arranged at the rear directly below the inner surface bottom of the supply air chamber C. The backup power supply 16 is arranged directly below the air supply opening 7.

[0026] Further, as shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4 it is worth specifically stating that a support plate 17 is fixedly connected to the center at the top of the unit housing 1. A support column 18 is fixedly connected directly behind the support plate 17. The bottom end of the support column 18 is fixedly connected to a regeneration fan 19. The air outlet of the regeneration fan 19 is in communication with the inside of the dehumidification chamber B. A heat insulation assembly 20 is arranged directly behind the regeneration fan 19.

Through the mixing chamber A, the dehumidification chamber B, and the supply air chamber C, fresh air enters through the fresh air inlet and then reaches the mixing chamber A, and then is transported to the dehumidification chamber B through the mixing chamber A for dehumidification treatment by the dehumidification wheel 13. The heat generated by the rotation of the dehumidification wheel 13 will be conducted by the cooling water in the water inlet pipe 10 and discharged through the water outlet pipe 11, so as to circulate and prevent overheating from damaging the dehumidification wheel 13 and affecting its service life, thereby reducing the dehumidification efficiency.

[0027] Further, as shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown in the figure, it is worth specifically explaining that a heat insulation cavity 2002 is provided inside the heat insulation housing 2001. The heat insulation cavity 2002 is interconnected with the inside of the dehumidification chamber B. At the bottom end of the side surface of the heat insulation cavity 2002, an annular outer frame 2003 is fixedly connected. At the top end of the inner surface of the annular outer frame 2003, four support rods 2004 arranged in an annular array are fixedly connected. At the inner side of the top ends of several support rods 2004, a mounting seat 2005 is fixedly connected. At the top end of the inner surface of the mounting seat 2005, a rotating motor 2006 is fixedly connected. The output end of the rotating motor 2006 is fixedly connected with a rotating shaft 2007. An annular connecting ring 2008 is fixedly connected to the outer surface of the rotating shaft 2007. Several fan blades 2009 arranged in an annular array are fixedly connected to the outer surface of the connecting ring 2008. A fixed buckle 2010 is fixedly connected to the top end of the rotating shaft 2007. Through the heat insulation component 20, when the power suddenly cuts off and the heat generated by the dehumidification wheel 13 in the dehumidification chamber B cannot be dissipated, the backup power supply 16 starts, causing the rotating motor 2006 to start. Thus, the output end of the rotating motor 2006 drives the rotating shaft 2007 to rotate, causing the rotating shaft 2007 to drive the fan blades 2009 to rotate to generate wind to neutralize the internal heat. During the rotation of the fan blades 2009, an air duct is formed, enabling the heat to flow to the outside through the air outlet 22 for heat dissipation, thereby improving the heat dissipation efficiency of the device.

[0028] Further, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, it is worth specifically explaining that the backup power supply 16 is electrically connected to the rotating motor 2006.

[0029] This solution has the following working process: First, cooling water flows in through the water inlet pipe 10, enabling fresh air to enter through the fresh air inlet and reach the mixing chamber A, and then being transported to the dehumidification chamber B through the mixing chamber A for dehumidification treatment by the dehumidification wheel 13. The heat generated by the rotation of the dehumidification wheel 13 will conduct heat through the cooling water in the water inlet pipe 10 and be discharged through the water outlet pipe 11 when passing through the mixing surface cooler 12 and the rear surface cooler 14. When the power suddenly cuts off and the heat generated by the dehumidification wheel 13 in the dehumidification chamber B cannot be dissipated, the backup power supply 16 starts, causing the rotating motor 2006 to start. Thus, the output end of the rotating motor 2006 drives the rotating shaft 2007 to rotate, causing the rotating shaft 2007 to drive the fan blades 2009 to rotate to generate wind to neutralize the internal heat. During the rotation of the fan blades 2009, an air duct is formed, enabling the heat to flow to the outside through the air outlet 22 for heat dissipation.

[0030] According to the above working process, it can be known that: through the mixing chamber A, the dehumidifying chamber B and the air supply chamber C, fresh air enters through the fresh air inlet and then reaches the mixing chamber A, and then is transported to the dehumidifying chamber B to be dehumidified by the dehumidifying rotor 13. The heat generated by the rotation of the dehumidifying rotor 13 will be conducted by the cooling water in the water inlet pipe 10 and discharged through the water outlet pipe 11, so as to circulate and prevent overheating from damaging the dehumidifying rotor 13 and affecting its service life, thereby reducing the dehumidification efficiency. Through the heat insulation component 20, when the power suddenly cuts off and the heat generated by the dehumidifying rotor 13 in the dehumidifying chamber B cannot be volatilized, the backup power supply 16 starts, so that the rotating motor 2006 starts. As a result, the output end of the rotating motor 2006 drives the rotating shaft 2007 to rotate, so that the rotating shaft 2007 drives the fan blades 2009 to rotate to generate wind to neutralize the internal heat. During the rotation of the fan blades 2009, an air duct will be formed so that the heat flows to the outside through the air outlet 22 for heat dissipation, thereby improving the heat dissipation efficiency of the device.
