[0021] Please refer to Figure 1 The utility model provides a ventilating equipment with heat recovery structure, include: ventilator shell 1 with second air inlet pipe 6, ventilator shell 1 one side is connected with first air inlet pipe 2 and air outlet pipe 3, first air inlet pipe 2 with air outlet pipe 3 one side all install fan body 4, fan body 4 is away from first air inlet pipe 2, air outlet pipe 3 one side is connected with filter box 5 through pipeline, second air inlet pipe 6 is connected in ventilator shell 1 one side through check valve.
[0022] The both ends of filter box 5 are connected with conveying pipe 7, the outer side of conveying pipe 7 is wrapped with heat preservation sponge 8, one end of conveying pipe 7 is connected with protective shell 9 away from filter box 5, protective shell 9 is sleeved in the end of fan body 4, and the one-way flow structure is formed between protective shell 9 and filter box 5 through the check valve connected in the middle of conveying pipe 7, and conveying pipe 7 and filter box 5 are integrated structure.
[0023] In specific implementation, the ventilation equipment with the heat recovery structure only needs to start the fan body 4 at one end of the first air inlet pipe 2 to suck the air with high temperature inside the breeding farm into the filter box 5 for filtration, and then the air with high temperature after filtration is discharged into the breeding farm again through the fan body 4 connected at one end of the air outlet pipe 3, so that the heat inside the breeding farm can be filtered and reused; and the fan body 4 also generates a large amount of heat during work, the air with high temperature can be gathered inside the fan body 4 through the protection shell 9, then the air pump is started, the heat around the fan can be transported to the filter box 5 through the conveying pipe 7, and the heat loss in the transmission process can be reduced through the heat preservation sponge 8 outside the conveying pipe 7, when the heat is transmitted to the inside of the filter box 5, the heat can be mixed with the air with lower temperature entering the filter box 5, so that the temperature of the fresh air can be increased, and the heat recovery and reuse effect is achieved.
[0024] Referring to Figure 1 With Figure 3 It can be known that, in use, the fan body 4 can be started according to the use requirement, the air with high temperature inside the breeding farm is sucked into the filter box 5 through the first air inlet pipe 2, the air is filtered through the air filter element 10 in the filter box 5, and then the air is discharged back into the breeding farm through the air outlet pipe 3, and the heat generated by the fan body 4 during work can be sucked into the filter box 5 through the air pump, so that the heat can be well recovered and reused.
[0025] The filter box 5 is internally provided with the air filter element 10, the first clamping block 11 is recessed installed at both ends of the air filter element 10, the rotating block 12 is internally installed in the first clamping block 11, the rotating shaft 13 is connected between one end of the two groups of rotating blocks 12 and the recess of the first clamping block 11, the connecting gear 14 is connected to the outer side of the two groups of rotating shafts 13, the gear rack 15 penetrating through the rotating block 12 is connected to one side of one group of connecting gears 14, the screw rod 16 penetrating through the filter box 5 is connected to the top of the gear rack 15 through a bearing, the second clamping block 17 is arranged at one end of the rotating block 12, the movable spring 18 is connected between the second clamping block 17 and the recess of the filter box 5, and the first clamping block 11 is internally installed in the filter box 5.
[0026] In practical implementation, when the air filter element 10 needs to be replaced, the ventilation equipment with heat recovery structure only needs to rotate the screw 16 at one end of the filter box 5. The screw 16 is threadedly connected to the filter box 5, and the screw 16 is connected to the rack 15 through a bearing. Therefore, rotating the screw 16 will drive the rack 15 to move. A connecting gear 14 is meshed on one side of the rack 15, and a rotating shaft 13 is connected through the middle of the connecting gear 14. Therefore, when the rack 15 moves, it will cause the connecting gear 14 to rotate, which in turn will drive the rotating shaft 13 to rotate. A rotating block 12 is connected to one side of the connecting shaft. Therefore, when the connecting shaft rotates, it will drive the rotating block 12 at one end to rotate downward. Since the two sets of connecting shafts are connected to each other through two sets of connecting gears 14, the other set of rotating shafts 13 will rotate with the rotating block under the cooperation of the connecting gears 14. When rotating block 12 rotates downwards, it no longer presses against the second locking block 17 at the top. Then, under the reset action of the movable spring 18, the second locking block 17 retracts into the groove of the first locking block 11. At this time, the second locking block 17 is not engaged with the groove of the filter element, so the filter element can be quickly removed from the inner wall of the filter box 5, making it convenient to replace the filter element. Conversely, the filter element can be engaged with the inside of the filter box 5 through the first locking block 11. Then, the screw 16 is rotated in the opposite direction, so that the screw 16 drives the connecting gear 14 to rotate in the opposite direction through the rack 15. When the connecting gear 14 rotates in the opposite direction, it will drive the rotating block 12 to rotate upwards through the rotating shaft 13, and push the second locking block 17 at one end out of the groove of the first locking block 11, so that the second locking block 17 engages with the groove of the filter element, making it convenient to replace and install the filter element.
[0027] See Figure 1 , Figure 2 and Figure 4 As can be seen, during use, depending on the condition of the filter element, the screw 16 can be rotated. With the cooperation of the rack 15 and the connecting gear 14, the rotating shaft 13 and the rotating block 12 will not squeeze the second locking block 17. Then, under the reset action of the movable spring 18, the second locking block 17 will retract into the groove of the first locking block 11. At this time, the filter element is not limited by the second locking block 17, and it can be quickly removed from the inside of the filter box 5 for replacement.
[0028] In summary, the ventilation equipment with heat recovery structure in use, first, the whole ventilation machine shell 1 is installed on the wall of the farm, and makes the first air inlet pipe 2 and air outlet pipe 3 towards the inside, the second air inlet pipe 6 towards the outside, when the farm is ventilated, only need to start fan body 4, make the air in the farm through the first air inlet pipe 2 into the filter box 5 in ventilation machine shell 1, simultaneously through air outlet pipe 3, the filtered air is discharged back to the farm, and the fan body 4 in air outlet pipe 3 will pass through the second air inlet pipe 6 and inhale the fresh air outside into the filter box 5, also can be discharged to the farm through air outlet pipe 3, to have the effect of the farm ventilation, this is the use characteristics of the ventilation equipment with heat recovery structure.
