As shown in fig. 1, 2 and 3, the present embodiment provides a circulating cooling water recovery device for a fuel cell power plant, which includes a main body 100, wherein the main body 100 includes a tank 1001.

The bottom end of the inside of the box 1001 is rotatably connected with a stirring shaft 1007, for example, the stirring shaft 1007 may be a propeller type stirring shaft 1007, and a first synchronizing wheel 1008 is sleeved on the stirring shaft 1007.

A buffer plate 1006 is fixedly arranged in the box 1001 near the upper end of the stirring shaft 1007, and a plurality of preformed holes 1010 are formed in the buffer plate 1006.

The inside of the case 1001 is rotatably connected to a rotation shaft 1014 through a bearing near the upper end of the buffer plate 1006, and the rotation shaft 1014 is sleeved with a second synchronizing wheel 1013.

The buffer plate 1006 has a hole 1011 formed on its surface, and the second synchronizing wheel 1013 is connected to the first synchronizing wheel 1008 by a synchronizing belt 1009 passing through the hole 1011.

The blade mechanism 200 comprises a rotating wheel 2004, the rotating wheel 2004 is sleeved on the rotating shaft 1014, and a plurality of blades 2001 are fixedly arranged on the outer side of the rotating wheel 2004.

Wherein, the box 1001 is provided with a spiral pipe 1012 near the upper end of the rotating wheel 2004, and the upper end surface of the spiral pipe 1012 is provided with a feeding pipe 1003.

According to the circulating cooling water recovery device for the fuel cell power plant, the spiral pipe 1012 is arranged at the water outlet end of the feed pipe 1003, when cooling water enters the box 1001 from the feed pipe 1003, the cooling water can be drained through the spiral pipe 1012, the impact force of the cooling water is reduced, and therefore the stirring shaft 1007 is prevented from being damaged due to the fact that the stirring shaft is subjected to large water flow impact, and the service life of the stirring shaft is prolonged.

When the cooling water entering the tank 1001 impinges on the blades 2001, the rotating shaft 1014 is driven to rotate, so that the stirring shaft 1007 at the bottom end is rotated by the transmission of the synchronous belt 1009, and the mixing between the cooling water and the medicament is promoted.

Moreover, through the internally mounted buffer board 1006 of box 1001 for the inside cooling water that enters into box 1001 can be blocked by buffer board 1006, reduces the impact force after the cooling water passes preformed hole 1010 of seting up on the buffer board 1006, and then can reduce the destruction to retrieving the mechanism.

Wherein, medicine case 1004 is installed to one side of box 1001, and medicine pipe one end of medicine case 1004 runs through box 1001 and extends to inside, through installation medicine case 1004, makes things convenient for its inside medicament to enter into the inside of box 1001.

The grooves 2002 are formed on one side of the blade 2001, and the grooves 2002 are formed on one side of the blade 2001, so that more cooling water can be loaded in the grooves 2002 when the blade 2001 contacts with the cooling water, and the rotating effect of the blade 2001 for driving the rotating shaft 1014 is improved.

One end of each blade 2001 is embedded with a strong magnet 2003.

As shown in fig. 4, a block 1015 is inserted in the medicine tube in a sliding manner, a spring 1016 is sleeved at one end of the block 1015, and two ends of the spring 1016 are respectively abutted against a protrusion on the block 1015 and a protrusion on the inner wall of the medicine tube. Wherein, the protrusion on the block 1015 can prevent the block 1015 from falling off from the medicine tube.

The medicine pipe is provided with a medicine outlet 1017 near the bottom side of the block 1015, the block 1015 is inserted through sliding, and a spring 1016 is sleeved at one end of the medicine pipe, so that the block 1015 seals the medicine outlet 1017 under the action of the elasticity of the spring 1016, and the medicine is prevented from entering the box 1001.

Wherein, the one end of the shutoff piece 1015 runs through the tip of medicine pipe and extends to outside to install the iron plate, adsorb between iron plate and the strong magnet 2003 and be connected, through the one end installation iron plate with the shutoff piece 1015, and make it adsorb with the strong magnet 2003 be connected, and then when blade 2001 rotates to medicine pipe one end, the strong magnet 2003 of blade 2001 one end installation adsorbs the iron plate of the one end installation of shutoff piece 1015, make the shutoff piece 1015 slide, thereby make shutoff piece 1015 and play medicine mouth 1017 separation, make the inside that the medicament in the medicament case 1004 enters into box 1001. When the blade 2001 rotates away, the iron block loses the adsorption of the strong magnet 2003, and the blocking 1015 returns under the elastic force of the spring 1016 to continuously seal the medicine outlet 1017.

Wherein, the bottom fixed mounting of box 1001 has support frame 1002, and discharging pipe 1005 is installed to the bottom side of box 1001, through installing discharging pipe 1005, conveniently collects the reuse to the cooling water that handles.

In using such a product, first, it is checked whether the joint of the product is fastened, the product is placed at a designated position after ensuring the integrity, then a cooling water pipe is connected to the feed pipe 1003, and when cooling water is introduced thereinto, the cooling water is first introduced through the spiral pipe 1012, by means of the spiral pipe 1012, and then the cooling water is introduced into the inside of the tank 1001 and contacts the blades 2001.

The grooves 2002 formed in the blades 2001 can carry more cooling water, so that the blades 2001 and the rotating wheel 2004 drive the rotating shaft 1014 to rotate.

The cooling water falls onto the baffle 1006 as it continues to flow and then flows out of the preformed holes 1010 in the baffle 1006.

As the shaft 1014 rotates, the stirring shaft 1007 also rotates in synchronization.

When the blade 2001 rotates to one end of the medicine box 1004, the strong magnet 2003 adsorbs the iron block, so that the block 1015 slides, thereby separating the block 1015 from the medicine outlet 1017, so that the medicine in the medicine box 1004 enters the inside of the box 1001.

When the blade 2001 rotates away, the iron block loses the adsorption of the strong magnet 2003, the blocking 1015 is reset under the action of the elastic force of the spring 1016, the medicine outlet 1017 is continuously closed, at this time, the dropped medicine is rapidly mixed with the cooling water stirred in the tank 1001 for reaction, and after the mixing is finished, the medicine is discharged out of the tank 1001 through the discharge pipe 1005.

In summary, the circulating cooling water recovery device for the fuel cell power plant can reduce the impact force of cooling water, protect the stirring shaft 1007 in the box 1001, effectively improve the recovery treatment effect of the cooling water and have higher practical value.
