Description

Technical Field

[0001] The present invention belongs to the technical field of ventilation equipment, and particularly relates to a ventilation device for a factory building with a filtering component and an operation method thereof. Background Art

[0002] A ventilation device for a factory building with a filtering component is a ventilation equipment specifically designed for industrial factory buildings. It combines ventilation and filtering functions, aiming to improve the air quality in the factory building and provide a healthier and safer working environment for employees.

[0003] In the existing ventilation devices for factory buildings, during use, in order to adapt to the environmental air humidity, ensure the humidity stability during the ventilation process, and avoid the influence of excessive humidity on the equipment in the factory building, a dehumidifying agent usually needs to be equipped in the ventilation device. However, the current dehumidifying agent is assembled in the ventilation device for static treatment. A large number of dehumidifying agents are stacked on top of each other, and their mutual areas are blocked. During the process of air volume inhalation, the contact area between the wet air and the dehumidifying agent is limited, and the moisture absorption capacity is weak. As a result, the humidity of the inhaled air after dehumidification is still relatively high, which affects the service life of the equipment in the factory building. At the same time, the dehumidifying agent after moisture absorption gradually loses its effectiveness and needs to be replaced regularly. However, after the dehumidifying agent stacked in the ventilation device loses its moisture absorption effectiveness, its structural stability becomes poor, and it is prone to breakage itself, resulting in an increased actual separation difficulty. The comprehensive ventilation and dehumidification effect is average, and the use effect is not good. Summary of the Invention

The support plate is installed with a rotating shaft through a middle bearing. The filtering part is a filtering cylinder, and filtering holes are opened on the outer side surface. A first gear is fixedly sleeved on the outer surface of the rotating shaft.

[0009] Preferably, the power part includes a motor and a second gear. The motor drives the second gear to rotate. The second gear meshes with the first gear. A closing plug is movably installed on the side surface of the installation cylinder. The number of the closing plugs is two. The two closing plugs respectively control the opening of the storage box and the guiding plate.

[0010] Preferably, the cleaning assembly includes a connecting plate, a connecting ring and a cleaning brush. The connecting plate is fixedly sleeved on the outer surface of the rotating shaft. The connecting ring is fixedly connected to the outer end of the connecting plate and is rotatably sleeved in the fitting groove. The cleaning brush is fixedly connected to the bottom surface of the connecting ring and is located outside the filtering part.

[0011] Preferably, the top and bottom surfaces of the storage box are both conical surfaces. The top of the guiding plate is a conical surface. The inner ring height of the storage box is lower than the outer ring height. The inner ring height of the guiding plate is higher than the outer ring height. The bottom sleeve is fixedly connected to the bottom of the storage box and is fixedly connected to the top of the guiding plate. The air suction groove is circumferentially opened on the outer side surface of the bottom sleeve. The composite dehumidification assembly is located above the exhaust fan.

[0012] Preferably, a heating assembly is fixedly sleeved on the outer surface of the rotating shaft. The heating assembly is located above the composite dehumidification assembly. The rotating shaft drives the heating assembly to rotate.

[0013] Preferably, the heating assembly includes an installation sleeve, an installation plate and a heating pipe. The installation sleeve is fixedly sleeved on the outer surface of the rotating shaft. The heating pipe is fixedly installed between two groups of installation plates distributed up and down. The installation plate is fixedly connected to the installation sleeve.

[0014] An operation method of a ventilation device for a factory building with a filtering component includes the following operation steps:

[0015] Step 1: During use, keep the exhaust fan running so that the external air of the ventilator is inhaled into the installation cylinder through the filtering part, and the inhaled air flows downward to the composite dehumidification component. The moisture in the inhaled air is adsorbed on the dehumidifying agent particles in the storage frame, passes through the communication groove and the air suction groove, and is input into the workshop through the bottom of the installation cylinder to complete the ventilation process;

[0016] Step 2: When the outer side of the filtering part is blocked, the ventilation volume is significantly reduced. Start the power part. The second gear in the power part drives the meshing first gear to rotate, thereby driving the rotating shaft to rotate, so that the rotating shaft drives the fixedly sleeved cleaning component to rotate. The connecting plate and the connecting ring in the cleaning component drive the cleaning brush to rotate synchronously, and the cleaning brushes distributed around the outer side of the filtering part rotate and rub continuously to complete the blockage cleaning of the outer side;

[0017] Step 3: When the humidity in the external environment is high, continue to keep the power part driving the rotating shaft to rotate, so that the rotating shaft drives the feeding block to rotate adaptively in the storage frame. The feeding block pushes the dehumidifying agent particles in the storage frame to roll through the convex parts on both sides, and the dehumidifying agent particles rolling along the conical surface automatically fall. Some of the dehumidifying agent particles that have absorbed moisture are broken and slide into the bottom groove of the feeding block. As the feeding block rotates, the fragmented dehumidifying agent particles after absorbing moisture are ground and fall into the bottom guiding plate through the communication groove;

[0018] Step 4: When ventilation is required in winter, since the temperature of the inhaled air is too low, start the heating tube in the heating component, and keep the rotating shaft driving the heating tube to rotate. The inhaled air absorbs heat fully to become hot air and is introduced into the workshop.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. By utilizing the rotation effect of the rotating shaft and cooperating with the structural design of the composite dehumidification component, the present invention enables the rotating shaft to drive the feeding block to rotate in the storage frame when rotating, and cooperates with the structural design of the feeding block to continuously disturb the filled dehumidifying agent particles in the storage frame during rotation, so that the dehumidifying agent particles roll fully in the storage frame. With the effect of the conical surface inside the storage frame, the internal dehumidifying agent particles are continuously pushed, tumbled and slide down. By utilizing the dynamic state of the dehumidifying agent particles and cooperating with guiding the inhaled air into the storage frame through the air suction groove and making full contact with the dynamic dehumidifying agent particles, the contact effect between the dehumidifying particles and the inhaled air is greatly improved. Through the action of dynamic movement, the adsorption area is increased, and the dehumidification intensity per unit time is greatly improved, avoiding the situation that the quickly inhaled humid air flows too fast to be fully dehumidified, and comprehensively improving the dehumidification effect.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] 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

Detailed implementation manners

[0035] 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.

[0036] As Figures 1 to 9 shown, the embodiment of the present invention provides a ventilation device for a factory building with a filtering component and its operation method, including an installation cylinder 1 and an exhaust fan 2 fixedly installed in the installation cylinder 1. A top cover component 3 is fixedly provided at the top of the installation cylinder 1. A filtering part 4 is fixedly sleeved at the top of the installation cylinder 1. A cleaning component 13 is rotatably arranged inside the top cover component 3. A rotating shaft 6 is rotatably arranged inside the installation cylinder 1. A power part 8 is fixedly provided at the top of the top cover component 3. The power part 8 drives the rotating shaft 6 to rotate. A composite dehumidification component 9 is fixedly installed inside the installation cylinder 1. A material pushing block 10 is rotatably arranged inside the composite dehumidification component 9. The rotating shaft 6 drives the cleaning component 13 and the material pushing block 10 to rotate synchronously. Protrusions are provided on both sides of the material pushing block 10, and reduced grooves are provided on both sides of the bottom.

[0037] The composite dehumidification component 9 includes a storage box 91, a communication groove 92, a bottom sleeve 93, a conical guide plate 94, and a suction groove 95. The storage box 91 is fixedly sleeved in the installation cylinder 1. The communication groove 92 is opened at the top of the storage box 91 and penetrates through the top of the storage box 91. The conical guide plate 94 is fixedly sleeved inside the installation cylinder 1 and is located below the storage box 91. The storage box 91 is filled with dehumidifying agent particles.

[0038] Embodiment 1: During the use process, keep the exhaust fan 2 started, so that the external air of the ventilator is inhaled into the installation cylinder 1 through the filtering part 4, and the inhaled air flows downward into the composite dehumidification component 9. The moisture in the inhaled air is adsorbed on the dehumidifying agent particles in the storage box 91, passes through the communication groove 92 and the suction groove 95, and is input into the workshop downward through the bottom of the installation cylinder 1 to complete the ventilation treatment. When the external environment has a large amount of moisture, continue to keep the power part 8 driving the rotating shaft 6 to rotate, so that the rotating shaft 6 drives the feeding block 10 to rotate adaptively in the storage box 91. The feeding block 10 pushes the dehumidifying agent particles in the storage box 91 to roll through the convex parts on both sides, and the dehumidifying agent particles rolling along the conical surface automatically fall. Some of the dehumidifying agent particles that have inhaled moisture are broken and slide into the bottom groove of the feeding block 10. As the feeding block 10 rotates, the fragmented and moisture-absorbed dehumidifying agent particles are ground and fall into the bottom guide plate 94 through the communication groove 92. When the outer side of the filtering part 4 is blocked, the ventilation volume is significantly reduced. Start the power part 8. The second gear in the power part 8 drives the meshing first gear 7 to rotate, thereby driving the rotating shaft 6 to rotate, so that the rotating shaft 6 drives the fixedly sleeved cleaning component 13 to rotate. The connecting plate 131 and the connecting ring 132 in the cleaning component 13 synchronously drive the cleaning brush 133 to rotate. The cleaning brushes 133 distributed around the outer side of the filtering part 4 continuously rotate and rub to complete the cleaning of the outer side to remove the blockage.

[0039] First of all, by utilizing the rotation effect of the rotating shaft 6 and cooperating with the structural design of the composite dehumidification component 9, when the rotating shaft 6 rotates, it drives the feeding block 10 to rotate in the storage box 91. And cooperating with the structural design of the feeding block 10, during the rotation process, the dehumidifying agent particles filled in the storage box 91 are continuously disturbed, so that the dehumidifying agent particles roll fully in the storage box 91. Cooperating with the effect of the conical surface inside the storage box 91, the internal dehumidifying agent particles are continuously pushed, tumbled and slide down. Utilizing the dynamic state of the dehumidifying agent particles, the inhaled air is introduced into the storage box 91 through the suction groove 95 and is fully contacted with the dynamic dehumidifying agent particles, which greatly improves the contact effect between the dehumidifying particles and the inhaled air. Through the action of dynamic movement, the adsorption area is increased, and the dehumidification intensity per unit time is greatly improved. It avoids the situation that the quickly inhaled wet air flows too fast and cannot be fully dehumidified, and comprehensively improves the dehumidification effect.

[0040] In addition, by making the filled dehumidifier particles tumble continuously, the stacked filled dehumidifier particles are fully dispersed and effectively contacted with the humid air, so that the comprehensive moisture absorption of the dehumidifier particles is more uniform, ensuring that the moisture absorption strength of all filled dehumidifier particles is consistent, avoiding local moisture absorption failure of the filled diluent particles without obvious moisture absorption treatment elsewhere, ensuring that the expiration time of the diluent particles is consistent, 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.

[0041] On the other hand, by utilizing the inclined surface design in the storage frame 91 and cooperating with the bottom groove of the material shifting block 10, the dehumidifier particles that have become invalid after absorbing moisture are gradually broken up during the shifting movement and slide down to the groove of the material shifting block 10, thereby cooperating with the rotation effect to further break up the invalid dehumidifier particles, and utilizing the connecting groove 92 to guide them to the guide plate 94 for isolation, so as to prevent the invalid dehumidifier from further affecting the invalid dehumidifier particles that have not fully absorbed moisture, and after separation, cooperate with the opening of the sealing plug 11 to achieve independent separation, thereby actually realizing convenient separation of the invalid dehumidifier particles, and at the same time, the dehumidifier particles in the storage frame 91 can be quickly and conveniently replenished.

[0042] On the other hand, by utilizing the rotating shaft 6, when realizing the disturbance treatment of the dehumidifier particles, the cleaning component 13 is synchronously driven to rotate. As the cleaning brush 133 in the rotating cleaning component 13 rubs along the outer side surface of the filter part 4, the filter part 4 is automatically cleared, and the blockages accumulated on the outer side surface during the filtration process are cleaned and separated, avoiding the influence of blockage on the air intake effect, thereby always maintaining a stable ventilation effect, and the actual clearing operation is simple and convenient.

[0043] Example 2: After a certain period of heating in winter, the air quality inside the factory building decreases and timely ventilation is needed. 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 into hot air and is passed into the factory building.

[0044] Firstly, by further utilizing the rotating shaft 6, the heating component 12 is driven to rotate synchronously during the rotation process. When short ventilation is needed in winter, the heating component 12 is started and the rotation effect is cooperated 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.

[0052] By utilizing the rotation of the cleaning assembly 13, the outer side of the filter part 4 is cleaned, thereby achieving self-cleaning and ensuring that the filter part 4 maintains stable filtering and ventilation processing.

[0053] Among them, the top and bottom surfaces of the storage frame 91 are both frustum surfaces, the top of the guide plate 94 is a frustum surface, the inner circle height of the storage frame 91 is lower than the outer circle height, the inner circle height of the guide plate 94 is higher than the outer circle height, the bottom sleeve 93 is fixedly connected to the bottom of the storage frame 91 and fixedly connected to the top of the guide plate 94, the air intake groove 95 is surrounded and opened on the outer surface of the bottom sleeve 93, and the composite dehumidification component 9 is located above the exhaust fan 2.

[0054] By utilizing the structural design of the composite dehumidification component 9 and matching the structural adaptation of the material feeding block 10, the dehumidifying agent particles are stirred to roll up and down during rotation, realizing dynamic disturbance, improving the contact effect with air, providing moisture absorption capacity, and further crushing and grinding the broken dehumidifying agent particles after moisture absorption to achieve separation.

[0057] An operation method of a ventilation device for a factory building with a filtering component includes the following operation steps:

[0058] The first step: During use, keep the exhaust fan 2 started, so that the external air of the ventilator is inhaled into the installation cylinder 1 through the filtering part 4, and the inhaled air flows downward to the composite dehumidification component 9. The moisture in the inhaled air is adsorbed on the dehumidifying agent particles in the storage frame 91, and passes through the communication groove 92 and the air suction groove 95, and then is input into the factory building through the bottom of the installation cylinder 1 to complete the ventilation treatment;

The installation sleeve (121) is fixedly sleeved on the outer surface of the rotating shaft (6). The heating pipe (123) is fixedly installed between two groups of installation plates (122) distributed up and down. The installation plate (122) is fixedly connected to the installation sleeve (121).

7. The operating method of a ventilation device for a factory building with a filtering component according to any one of claims 1-6, characterized in that: It includes the following operation steps: First step: During the use process, keep the exhaust fan (2) started, so that the external air of the ventilator is inhaled into the installation cylinder (1) through the filtering part (4), and the inhaled air flows downward into the composite dehumidification assembly (9). The moisture in the inhaled air is adsorbed on the dehumidifying agent particles in the storage frame (91), passes through the communication groove (92) and the air suction groove (95), and is input into the workshop through the bottom of the installation cylinder (1) downward to complete the ventilation treatment; Second step: When the outer side surface of the filtering part (4) is blocked and the ventilation volume is significantly reduced, start the power part (8). The second gear in the power part (8) drives the meshing first gear (7) to rotate, thereby driving the rotating shaft (6) to rotate, so that the rotating shaft (6) drives the fixedly sleeved cleaning assembly (13) to rotate. The connecting plate (131) and the connecting ring (132) in the cleaning assembly (13) synchronously drive the cleaning brush (133) to rotate. The cleaning brush (133) surrounding the outer side surface of the filtering part (4) rotates and rubs continuously to complete the blockage cleaning of the outer side surface; Step 3: When the humidity of the external environment is relatively high, continue to keep the power unit (8) driving the rotating shaft (6) to rotate, so that the rotating shaft (6) drives the material distributing block (10) to rotate adaptively in the storage box (91). The material distributing block (10) pushes the desiccant particles in the storage box (91) to roll through the convex parts on both sides, and the desiccant particles rolling along the conical surface automatically fall. Some of the desiccant particles that have absorbed moisture are broken and slide into the bottom groove of the material distributing block (10). As the material distributing block (10) rotates, the fragmented desiccant particles after absorbing moisture are ground and fall into the bottom guide plate (94) through the communication groove (92). Step 4: When ventilation is required in winter, since the temperature of the inhaled air is too low, start the heating tube (123) in the heating component (12), and keep the rotating shaft (6) driving the heating tube (123) to rotate. The inhaled air fully absorbs heat to become hot air and is introduced into the workshop.
