Specific embodiments

[0051] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0052] The embodiments of the energy-saving ventilation device for industrial plant design are as follows:

[0053] Combined with the attached Figures 1-9 , in one embodiment of the present invention, an energy-saving ventilation device for industrial plant design may include: a ventilation duct 1, a filtering component 2, a limiting component 3, a discharge hole 6, a feeding hole 7, a recycling component 4, and a feeding component 5. Among them, for the ventilation duct 1, a fan is provided at its air outlet end; the filtering component 2 is located at the air inlet end of the ventilation duct 1; the limiting component 3 is located inside the ventilation duct 1, movably connecting the ventilation duct 1 and the filtering component 2 and restricting the maximum moving position of the filtering component 2 inside the ventilation duct 1; the discharge hole 6 is opened on the ventilation duct 1; the feeding hole 7 is opened on the ventilation duct 1 and corresponds to the discharge hole 6; the recycling component 4 is located below the ventilation duct 1 and corresponds to the maximum moving position of the limiting component 3, cooperating with the corresponding discharge hole 6 on the ventilation duct 1; the feeding component 5 is located above the ventilation duct 1 and corresponds to the position of the recycling component 4, cooperating with the feeding hole 7 on the ventilation duct 1. Specifically, by respectively arranging the feeding component 5 and the recycling component 4 on the upper and lower sides of the ventilation duct 1, a plurality of filtering components 2a are pre-stored inside the feeding component 5. Inside the ventilation duct 1, the currently used filtering component 2b will move towards the inside of the ventilation duct 1 as it is continuously blocked by dust. Under the action of the limiting component 3, when the filtering component 2b is blocked by dust to a certain extent, the filtering component 2b falls into the recycling component 4 through the discharge hole 6, and the reserved filtering component 2a will enter the ventilation duct 1 through the feeding hole 7 to replace the original filtering component 2b. The whole process is automatically completed, replacing the manual regular replacement of the filtering component 2, reducing the labor intensity of the staff, and preventing the phenomenon that the ventilation duct 1 cannot be unblocked in time, which affects the normal ventilation of the plant.

[0054] In order to facilitate those skilled in the art to fully understand the technical solution of the present application, to understand how the limit assembly 3 limits the movement of the filter assembly 2b, and at which position the filter assembly 2b is replaced, the structure of the limit assembly 3 is further described. In this embodiment, the limit assembly 3 may include: a support frame 33, located below the filter assembly 2, and fixed at both ends to the inner wall of the ventilation duct 1; a first spring 31, located on the support frame 33, for limiting the position of the filter assembly 2 and resetting it after replacement; a first spring 31, a pad 32, and a support frame 33. Among them, the pad 32 is located between the first spring 31 and the filter assembly 2, and is used to support the filter assembly 2. Specifically, as Figure 2 The direction of the middle arrow is the direction of airflow. When the ventilation duct 1 is working, the fan starts to draw external air into the factory building. The dust in the air passes through the filter component 2 and is filtered on the surface of the filter component 2. As the filter component 2 is blocked, the airflow generated by the fan inside the ventilation duct 1 gradually increases the impact force on the filter component 2. This is because the diameter of the air vents on the surface of the filter component 2 is decreasing, and the airflow is difficult to pass through the filter component 2 in time. Therefore, the thrust of the airflow on the filter component 2 gradually increases, and the filter component 2 blocks the filter component 2 through the first spring 31 between the pad 32 and the support frame 33. As the airflow thrust on the filter component 2 increases, the first spring 31 is gradually compressed, causing the filter component 2 to move deep into the ventilation duct 1. Since the inner diameter of the discharge hole 6 is the same as the size of the filter component 2, when the filter component 2 moves to coincide with the discharge hole 6, under the action of gravity, the filter component 2 is separated from the ventilation duct 1 through the discharge hole 6, and replacement begins.

[0055] In order to facilitate those skilled in the art to fully understand the technical solution of the present application and to clearly understand how the recovery component 4 recovers the filter component 2, the structure of the recovery component 4 is further described. In this embodiment, the recovery component 4 may include: a pillar 41 and a recovery box 42. Among them, the recovery box 42 is located below the ventilation duct 1, and the feed port corresponds to the position of the discharge hole 6; the pillar 41 is located at the feed end of the recovery box 42, and is used to fix the recovery box 42 and the ventilation duct 1; the early warning component 8 is located inside the recovery box 42. Specifically, when the filter component 2 is separated from the ventilation duct 1 through the discharge hole 6, since the discharge hole 6 corresponds to the feed port of the recovery box 42, and the recovery box 42 is fixed directly below the ventilation duct 1 through the pillar 41, the filter component 2 will fall into the recovery box 42 to complete the recovery of the filter component 2.

[0056] To facilitate those skilled in the art to fully understand the technical solution of the present application and clearly understand how the warning component 8 warns the staff, the structure of the warning component 8 will be further described. In this embodiment, the warning component 8 may include: a button 81, a support block 82, a second spring 83, and a receiving plate 84. Among them, the support block 82 is located inside the recycling bin 42 and is snap-connected to the inner wall of the recycling bin 42 at both ends; the receiving plate 84 is located inside the recycling bin 42 and is slidably connected thereto; the button 81 is located below the receiving plate 84, and the second spring 83 is located between the receiving plate 84 and the button 81. When the second spring 83 is at the maximum compression amount, the receiving plate 84 triggers the button 81. Specifically, when replacing the filter component 2 blocked by dust, the replaced filter component 2 will enter the inside of the recycling bin 42 through the discharge hole 6 and be received by the receiving plate 84. When the receiving plate 84 receives the weight of the filter component 2, it will compress the second spring 83 and move downward. As the replacement continues, when all the reserved filter components 2 are used up, the receiving plate 84 squeezes the button 81, causing the button 81 to be triggered. Since the button 81 controls an external alarm through an electrical signal, the external alarm is activated to notify the staff to deal with the blocked filter component 2, avoiding the consequence that the filter components 2 cannot be replenished in time after all are replaced and used up.

[0057] For the convenience of those skilled in the art to fully understand the technical solution of the present application and clearly understand how the discharging component 5 detects and completes the replacement of the filtering component 2, the structure of the discharging component 5 will be further described. In this embodiment, the discharging component 5 includes: a discharging box 51, located outside the ventilation duct 1 and communicating with the inside of the ventilation duct 1 through a feeding hole 7; a top plate 53, located inside the discharging box 51 and used to keep the filtering components 2 stacked tightly; a third spring 54, located between the top plate 53 and the inner wall of the discharging box 51 and in a compressed state under normal conditions. A baffle 55 is located below the feeding hole 7; a fixing block 57 is located on the inner wall of the ventilation duct 1 and fixed on the side of the baffle 55 away from the filtering component 2; a guide post 56 has one end fixed on the baffle 55 and the other end passing through the fixing block 57 in an inserted manner; a fourth spring 52 is sleeved on the guide post 56 between the baffle 55 and the fixing block 57. Specifically, during the process of the filtering component 2b being pushed by the air flow, the baffle 55 covering the surface of the feeding hole 7 is synchronously squeezed. When the baffle 55 is squeezed, the fourth spring 52 is compressed. Since the guide post 56 is inserted through the fixing block 57, the moving direction of the baffle 55 remains straight. Initially, the baffle 55 blocks the filtering component 2a inserted into the feeding hole 7 to prevent it from falling under the action of gravity. When the filtering component 2b completely coincides with the discharging hole 6, the baffle 55 is squeezed out of the feeding hole 7, that is, it no longer blocks the filtering component 2a. Therefore, under the action of gravity, the filtering component 2b detaches from the ventilation duct 1 through the discharging hole 6, and the filtering component 2a enters the inside of the ventilation duct 1 through the feeding hole 7. When a part of the filtering component 2b detaches from the ventilation duct 1, a part of the filtering component 2a enters the ventilation duct 1. At this time, the non-dust-blocked filtering component 2a and the dust-blocked filtering component 2b jointly block the air flow. Due to the addition of the filtering component 2a, the thrust of the air flow on the filtering component 2 inside the ventilation duct 1 is reduced. Therefore, as the filtering component 2b further partially detaches from the ventilation duct 1, the filtering component 2a further enters the ventilation duct 1. The resultant force formed by the extrusion force of the first spring 31 on the filtering component 2b through the backing plate 32 and the thrust of the air flow on the filtering component 2b gradually increases in the opposite direction of the air flow. Therefore, when the filtering component 2b completely detaches from the ventilation duct 1, the filtering component 2a completely enters the ventilation duct 1. Under the action of the resultant force formed by the first spring 31 and the air flow thrust, the filtering component 2a is pushed to move towards the air inlet of the ventilation duct 1. As the first spring 31 resumes its deformation and the elastic force decreases, the filtering component 2a replaces the original position of the filtering component 2b to complete the replacement of the filtering component 2. The baffle 55 resets under the action of the fourth spring 52, and then the above process is repeated when the filtering component 2 is blocked by dust again.In addition, when the filtering component 2a falls into the ventilation duct 1, the third spring 54 inside the discharging box 51 continuously presses against the top plate 53, and the top plate 53 presses against the reserved filtering component 2, causing the filtering component 2 to be inserted into the feeding hole 7 again. Moreover, the frictional force between the filtering components 2 and between the top plate 53 and the filtering component 2 is much smaller than the effect of gravity on the filtering component 2. Therefore, the frictional force will not affect the movement of the filtering component 2.

[0058] In order to ensure the continuous replacement of the filtering component 2, in this embodiment, multiple filtering components 2 are provided, and the part located inside the discharging box 51 is used as a reserve. Initially, there is a filtering component 2 inserted into the feeding hole 7 and blocked by the baffle 55. Specifically, it facilitates the continuous replacement of the filtering component 2.

[0059] Since the filter screen is relatively thin and not conducive to installation and fixation, in this embodiment, the filtering component 2 is formed by stacking multiple metal filter screens and has a certain thickness. Specifically, it facilitates the fixation and replacement of the filtering component 2.

[0060] During use, a discharging component 5 and a recycling component 4 are respectively arranged on the upper and lower sides of the ventilation duct 1. Multiple filtering components 2a are pre-stored inside the discharging component 5. Inside the ventilation duct 1, the currently used filtering component 2b will move further into the ventilation duct 1 as it is continuously blocked by dust. Under the action of the limiting component 3, when the filtering component 2b is blocked by dust to a certain extent, the filtering component 2b falls into the recycling component 4 through the discharging hole 6, and the reserved filtering component 2a will enter the ventilation duct 1 through the feeding hole 7 to replace the original filtering component 2b. The whole process is automatically completed, replacing the manual periodic replacement of the filtering component 2, reducing the labor intensity of the staff, and there will be no phenomenon that the ventilation duct 1 is blocked and cannot be dredged in time, affecting the normal ventilation of the factory building. When replacing the filtering component 2 blocked by dust, the replaced filtering component 2 will enter the recycling box 42 through the discharging hole 6 and be received by the receiving plate 84. When the receiving plate 84 receives the weight of the filtering component 2, it will compress the second spring 83 and move downward. As the replacement continues, when all the reserved filtering components 2 are used up, the receiving plate 84 presses against the button 81, causing the button 81 to be triggered. Since the button 81 controls an external alarm through an electrical signal, the external alarm is activated to notify the staff to process the blocked filtering component 2, avoiding the consequence that all the filtering components 2 cannot be replenished in time after being replaced and used.

[0061] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
