Description

Technical Field

[0001] The invention belongs to the technical field of ventilation equipment, and in particular relates to a factory ventilator with a filter component and an operating method thereof. Background Art

[0002] The factory ventilator with filter assembly is a ventilation device designed specifically for industrial plants. It combines ventilation and filtration functions to improve the air quality in the plant and provide employees with a healthier and safer working environment.

[0003] In the prior art, factory ventilators are usually equipped with dehumidifiers during use in order to adapt to the humidity of the ambient air, ensure the humidity stability during ventilation, and avoid the impact of excessive humidity on the equipment in the factory. However, the current dehumidifiers are installed in the ventilators for static treatment. A large number of dehumidifiers are stacked on each other, and their areas are shielded from each other. During the process of air intake, the contact area between the wet air and the dehumidifier is limited, and the moisture absorption capacity is weak, so that the humidity of the air after dehumidification is still relatively high, affecting the life of the equipment in the factory. At the same time, the dehumidifier gradually loses its effectiveness after moisture absorption and needs to be replaced regularly. However, the dehumidifiers accumulated in the ventilator lose their structural stability after moisture absorption and become easily broken, which increases the difficulty of actual separation. The overall ventilation and dehumidification effect is average, and the use effect is not good. Summary of the invention

[0013] A method for operating a factory ventilator with a filter assembly comprises the following steps: Step 1: During use, keep the exhaust fan started, so that the air outside the ventilator is sucked into the installation cylinder through the filter part, and the sucked air flows downward to the composite dehumidification component. The moisture in the sucked air is adsorbed on the dehumidifier particles in the storage frame, passes through the connecting groove and the suction groove, and is input into the factory through the bottom of the installation cylinder downward to complete the ventilation process; Step 2: When the outer side of the filter is clogged, the ventilation volume is significantly reduced, and the power unit is started. The gear 2 in the power unit drives the meshing gear 1 to rotate, thereby driving the rotating shaft to rotate, so that the rotating shaft drives the fixed sleeve cleaning component to rotate, and the connecting plate and connecting ring in the cleaning component synchronously drive the cleaning brush to rotate, and the cleaning brush distributed around the outer side of the filter continuously rotates and rubs to complete the blockage of the outer side; Step 3: When the external environment is humid, the power unit continues to drive the rotating shaft to rotate, so that the rotating shaft drives the material-dividing block to rotate adaptively in the storage frame. The material-dividing block pushes the dehumidifier particles in the storage frame to roll through the protrusions on both sides, and the dehumidifier particles rolling along the round table surface automatically fall down, and some of the dehumidifier particles that absorb moisture are broken and slide into the bottom groove of the material-dividing block. As the material-dividing block rotates, the broken dehumidifier particles that absorb moisture are ground and fall into the bottom guide plate through the connecting groove; Step 4: When ventilation is needed in winter, as the temperature of the inhaled air is too low, start the heating tube in the heating assembly, and keep the shaft to drive the heating tube to rotate, so that the inhaled air fully absorbs heat into hot air and passes into the factory.

[0014] The beneficial effects of the present invention are as follows: 1. The present invention utilizes the rotation effect of the rotating shaft and cooperates with the structural design of the composite dehumidification component, so that when the rotating shaft rotates, it drives the material block to rotate in the storage frame, and cooperates with the structural design of the material block to continuously disturb the dehumidifier particles filled in the storage frame during the rotation process, so that the dehumidifier particles can fully roll in the storage frame, and cooperate with the effect of the internal frustum of the storage frame. The internal dehumidifier particles are continuously pushed, rolled and slid down, and the dynamic state of the dehumidifier particles is utilized, and the inhaled air is introduced into the storage frame through the air suction groove, and fully contacts with the dynamic dehumidifier particles, thereby greatly improving the contact effect between the dehumidifier particles and the inhaled air. Through the effect of dynamic movement, the adsorption area is increased, and the dehumidification intensity per unit time is greatly improved, so as to avoid the rapid flow of the rapidly inhaled humid air and the inability to fully dehumidify, thereby comprehensively improving the dehumidification effect.

[0015] 2. The present invention makes the filled dehumidifier particles tumble continuously, so that the stacked filled dehumidifier particles are fully dispersed and effectively contact with the humid air, so that the comprehensive moisture absorption of the dehumidifier particles is more uniform, and the moisture absorption strength of all filled dehumidifier particles is guaranteed to be consistent, avoiding local moisture absorption failure of the filled diluent particles without obvious moisture absorption treatment in other places, ensuring the consistency of the expiration time of the diluent particles, and avoiding the waste of a large number of dehumidifier particles that have not failed during replacement, thereby greatly improving the utilization rate of the dehumidifier particles during ventilation and dehumidification, and reducing the input amount and replacement frequency.

[0016] 3. The present invention utilizes the inclined surface design in the storage frame in conjunction with the bottom groove of the material shifting block, so that the dehumidifier particles that have become invalid after absorbing moisture are gradually broken up during the shifting motion and slide down to the groove of the material shifting block, thereby cooperating with the rotation effect to further break up the invalid dehumidifier particles, and utilizes the connecting groove to guide them to the guide plate for isolation, thereby preventing the invalid dehumidifier from further affecting the invalid dehumidifier particles that have not fully absorbed moisture, and after separation, the sealing plug is opened to achieve independent separation, thereby actually realizing convenient separation of the invalid dehumidifier particles and quickly realizing convenient replenishment of the dehumidifier particles in the storage frame.

[0017] 4. The present invention utilizes a rotating shaft to simultaneously drive the cleaning component to rotate while achieving the disturbance treatment of the dehumidifier particles. As the cleaning brush in the rotating cleaning component rubs along the outer side of the filter part, the filter part is automatically unblocked, and the blockages accumulated on the outer side during the filtration process are cleaned and separated to avoid blockages that affect the air intake effect, thereby always maintaining a stable ventilation effect, and the actual unblocking operation is simple and convenient.

[0018] 5. The present invention further utilizes the rotating shaft to drive the heating component to rotate synchronously during the rotation process. When short ventilation is needed in winter, the heating component is started and the rotation effect is combined to heat the inhaled cold air, thereby achieving the effect of heating and ventilation. While achieving ventilation, the influence of the inhaled cold air on the interior of the factory is avoided. Under the rotation effect, the heating effect is good, the heating is uniform, and the use effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

The conical guide plate 94 is fixedly sleeved inside the mounting tube 1 and is located below the storage frame 91. The storage frame 91 is filled with dehumidifier particles.

[0022] Embodiment 1: During use, the exhaust fan 2 is kept started so that the air outside the ventilator is sucked into the installation cylinder 1 through the filter unit 4, and the sucked air flows downward to the composite dehumidification component 9, and the moisture in the sucked air is adsorbed on the dehumidifier particles in the storage frame 91, and passes through the connecting groove 92 and the suction groove 95, and is downwardly input into the factory through the bottom of the installation cylinder 1 to complete the ventilation treatment. When the humidity of the external environment is relatively high, the power unit 8 continues to drive the rotating shaft 6 to rotate, so that the rotating shaft 6 drives the material block 10 to rotate adaptively in the storage frame 91, and the material block 10 pushes the dehumidifier particles in the storage frame 91 to roll through the protrusions on both sides, and the dehumidifier particles rolling along the round table surface automatically As the dehumidifier particles fall, some of the moisture absorbed by the dehumidifier particles break and slide into the bottom groove of the material disc 10. As the material disc 10 rotates, the broken moisture-absorbing dehumidifier particles are ground and fall into the bottom guide plate 94 through the connecting groove 92. When the outer side of the filter part 4 is blocked, the ventilation volume is significantly reduced, and the power unit 8 is started. The gear 2 in the power unit 8 drives the meshing gear 1 7 to rotate, thereby driving the rotating shaft 6 to rotate, so that the rotating shaft 6 drives the fixed sleeve cleaning component 13 to rotate, and the connecting plate 131 and the connecting ring 132 in the cleaning component 13 synchronously drive the cleaning brush 133 to rotate, and the cleaning brush 133 distributed on the outer side of the filter part 4 continuously rotates and rubs to complete the outer side cleaning.

[0023] Firstly, by utilizing the rotation effect of the rotating shaft 6 and cooperating with the structural design of the composite dehumidification component 9, the rotating shaft 6 drives the material block 10 to rotate in the storage frame 91 when it rotates, and cooperating with the structural design of the material block 10, the dehumidifier particles filled in the storage frame 91 are continuously disturbed during the rotation process, so that the dehumidifier particles can fully roll in the storage frame 91, and cooperating with the effect of the internal frustum of the storage frame 91, the internal dehumidifier particles are continuously pushed, rolled and slid down, and the dynamic state of the dehumidifier particles is utilized, and the inhaled air is introduced into the storage frame 91 through the air intake groove 95, and fully contacts with the dynamic dehumidifier particles, thereby greatly improving the contact effect between the dehumidifier particles and the inhaled air, and through the action of dynamic movement, the adsorption area is increased, and the dehumidification intensity per unit time is greatly improved, so as to avoid the rapid flow of the rapidly inhaled humid air and the inability to fully dehumidify, thereby comprehensively improving the dehumidification effect.

A factory ventilator with a filter assembly according to claim 7, characterized in that: The heating assembly (12) comprises a mounting sleeve (121), a mounting plate (122) and a heating tube (123); the mounting sleeve (121) is fixedly sleeved on the outer surface of the rotating shaft (6); the heating tube (123) is fixedly mounted between two groups of mounting plates (122) distributed up and down; and the mounting plate (122) is fixedly connected to the mounting sleeve (121).

9. A method for operating a factory ventilator with a filter assembly according to any one of claims 1 to 8, characterized in that: The steps include: Step 1: During use, the exhaust fan (2) is kept started, so that the air outside the ventilator is sucked into the installation cylinder (1) through the filter portion (4), and the sucked air flows downward to the composite dehumidification component (9), and the moisture in the sucked air is adsorbed on the dehumidifier particles in the storage frame (91), passes through the connecting groove (92) and the suction groove (95), and is input into the factory building through the bottom of the installation cylinder (1), completing the ventilation process; Step 2: When the outer side of the filter portion (4) is clogged, the ventilation volume is significantly reduced, and the power unit (8) is started. The gear 2 in the power unit (8) drives the meshed gear 1 (7) to rotate, thereby driving the rotating shaft (6) to rotate, so that the rotating shaft (6) drives the fixed sleeve cleaning component (13) to rotate, and the connecting plate (131) and the connecting ring (132) in the cleaning component (13) synchronously drive the cleaning brush (133) to rotate, and the cleaning brush (133) distributed around the outer side of the filter portion (4) continuously rotates and rubs, thereby completing the blockage removal of the outer side; Step 3: When the external environment is humid, the power unit (8) continues to drive the rotating shaft (6) to rotate, so that the rotating shaft (6) drives the material shifting block (10) to rotate adaptively in the storage frame (91), and the material shifting block (10) pushes the dehumidifier particles in the storage frame (91) to roll through the protrusions on both sides, and the dehumidifier particles rolling along the round table surface automatically fall down, and some of the dehumidifier particles that absorb moisture are broken and slide into the bottom groove of the material shifting block (10). As the material shifting block (10) rotates, the broken dehumidifier particles that have absorbed moisture are ground and fall into the bottom guide plate (94) through the connecting groove 92; Step 4: When ventilation is required in winter, as the temperature of the inhaled air is too low, the heating tube (123) in the heating assembly (12) is started, and the rotating shaft (6) is kept to drive the heating tube (123) to rotate, so that the inhaled air fully absorbs heat to become hot air and is passed into the factory building.
