Description

Technical Field

[0001] This utility model relates to the field of deodorization technology, and in particular to a fiberglass deodorization box. Background Technology

[0002] Fiberglass deodorization boxes, also known as fiberglass biological deodorization boxes, are a type of high-efficiency air purification equipment that integrates air filtration and purification functions with disinfection and sterilization. They are mainly used to treat malodorous gases generated during various industrial and domestic wastewater treatment processes.

[0003] When the fiberglass deodorizing box is in operation, the odorous gas is first sent into the deodorizing box through the air inlet. After pretreatment (removing particulate matter from the gas through a filter screen or other filtration device), the gas enters the biodegradation zone, where microorganisms on the biological packing adsorb, absorb, and degrade the organic pollutants in the harmful gas, transforming them into non-toxic, harmless, and odorless substances. After purification through the above biological process, the gas is discharged through the air outlet. When the fiberglass deodorizing box pretreats the odorous gas through the filter screen, prolonged use can cause the filter screen to become clogged, reducing filtration efficiency. Therefore, the filter screen needs to be replaced regularly. Existing fiberglass deodorizing boxes require disconnecting the power supply and stopping the device before replacing the filter screen. After replacement, the power supply is restarted, resulting in reduced working efficiency. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the existing technology, the purpose of this utility model is to provide a fiberglass deodorizing box that solves the problems of filter clogging and the need to cut off the power and stop the machine when replacing the filter, resulting in low working efficiency.

[0005] The technical solution of this utility model is as follows: It includes a box body and a biofilm. A connecting plate is provided inside the upper part of the box body. Arc-shaped plates are respectively connected to the left and right edges of the top surface of the connecting plate. The upper ends of the arc-shaped plates are connected to the inner top surface of the box body. Arc-shaped filter screens are fitted between the opposite ends of the two arc-shaped plates. The upper ends of the two filter screens movably penetrate the top plate of the box body, and the lower ends contact the connecting plate. The two arc-shaped plates, the two filter screens, and the connecting plate together form a cylinder with an open upper end. A scraper is provided inside the cylinder along the diameter direction, and the scraper divides the interior of the cylinder into two cavities. The body has a rotating shaft rotatably connected to the center of the top surface of the connecting plate. A scraper is fixedly sleeved on the rotating shaft. The upper end of the rotating shaft movably passes through the top plate of the box. A driving component is provided on the outer top surface of the box, and the driving component drives the rotating shaft to rotate circumferentially. An air inlet pipe is provided on any of the arc-shaped plates. The air inlet end of the air inlet pipe extends outside the box, and the air outlet end of the air inlet pipe is connected to one of the cavities. Multiple layers of biofilm are sequentially arranged in the box below the connecting plate. An exhaust pipe is provided on the peripheral wall of the box, located below the multiple layers of biofilm.

[0006] The beneficial effects of this utility model are:

[0007] 1. The cylinder is divided into two chambers by a scraper. When any filter needs to be replaced, simply engage the fan ring plate with the gear through the teeth, or move the fan ring plate away from the gear, to disconnect the chamber containing the filter to be replaced from the air inlet pipe. This allows the filter to be replaced without stopping the deodorizing box, thus improving the working efficiency of the deodorizing box.

[0008] 2. Even if the filter screen does not need to be replaced, the fan ring plate can be driven to engage with the gear, or the fan ring plate can be driven away from the gear to clean the filter screen. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0015] like Figures 1-4As shown, a fiberglass deodorizing box includes a box body 1 and a biofilm 16. The box body 1 is a hollow cuboid with its upper opening sealed by a top plate 17. A connecting plate 4 is provided inside the upper part of the box body 1. The connecting plate 4 is a circular plate with a gap between its circumferential surface and the inner side of the box body. Arc-shaped plates 2 are respectively connected to the left and right sides of the top edge of the connecting plate 4. The upper ends of the arc-shaped plates 2 are connected to the inner top surface of the box body 1. Arc-shaped filters 3 are clamped between the opposite ends of the two arc-shaped plates 2. The upper ends of the two filters 3 movably penetrate the top plate 17 of the box body 1, and the lower ends contact the connecting plate 4. The two arc-shaped plates 2, the two filters 3, and the connecting plate 4 together form a cylinder with an upper opening. A scraper 6 is provided inside the cylinder along the diameter direction. The scraper 6 removes the circular... The cylinder is divided into two cavities. A rotating shaft 5 is rotatably connected to the center of the top surface of the connecting plate 4. A scraper 6 is fixedly sleeved on the rotating shaft 5. The upper end of the rotating shaft 5 movably passes through the top plate of the box 1. The top surface of the scraper 6 slides in contact with the inner top surface of the box 1, and the bottom surface slides in contact with the connecting plate 4. A driving component is provided on the outer top surface of the box 1. The driving component drives the rotating shaft 5 to rotate circumferentially. An air inlet pipe 12 is provided on any one of the arc-shaped plates 2. The air inlet end of the air inlet pipe 12 extends outside the box 1, and the air outlet end of the air inlet pipe 12 is connected to one of the cavities. Multiple layers of biofilm 16 are sequentially arranged in the box 1 below the connecting plate 4. An exhaust pipe 13 is provided on the periphery of the box 1, located below the multiple layers of biofilm 16.

[0016] The arc-shaped protrusions of the two arc-shaped plates 2 are opposite to each other, and the central angle of the arc-shaped plates 2 is 90 degrees. The arc-shaped protrusions of the two filter screens 3 are opposite to each other, and the central angle of the filter screens 3 is 90 degrees.

[0017] The driving component includes a torsion spring 8, a motor 9, and a fan ring plate 10. The torsion spring 8 is sleeved on the rotating shaft 5 on the upper side of the housing 1. One end of the torsion spring 8 is connected to the peripheral wall of the rotating shaft 5, and the other end is connected to the top plate of the housing 1. A gear 7 is fixedly connected to the upper end of the rotating shaft 5. The motor 9 is fixedly connected to the outer top surface of the housing 1. The output shaft of the motor 9 is connected to the fan ring plate facing upward. Multiple teeth 11 are equidistantly arranged on the outer ring surface of the fan ring plate 10. When the outer ring surface of the fan ring plate 10 faces the gear 7, the fan ring plate 10 meshes with the gear 7 through the teeth 11.

[0018] The fan ring plate 10 is a fan-shaped plate with a central angle of α, where 90° < α < 110°. The inner ring surface of the fan ring plate 10 is fixedly connected to the outer wall of the output shaft of the motor 9.

[0019] The scraper 6 is a rectangular plate. When the teeth 11 on the fan ring plate mesh with the gear 7, the torsion spring 8 is in a torsional state. The two end faces of the scraper 6 slide in contact with the arc surfaces of the two filter screens 3 in a circumferential manner. After the teeth 11 on the fan ring plate disengage from the gear 7, the torsion spring 8 returns to its natural state, and the two end faces of the scraper 6 contact the arc surfaces of the two arc plates 2 in a natural state.

[0020] Each filter screen 3 has a slot 14 of equal height on both end faces, and each arc plate 2 has a protrusion 15 of equal height on both end faces. The protrusion 15 and the arc plate 2 are integral structures, and the protrusion 15 on each arc plate 2 extends into the adjacent slot 14.

[0021] Each of the filter screens 3 has a handle 18 on its top surface.

[0022] In use, the odor is introduced into one of the cavities of the cylinder through the air inlet pipe 12. When the scraper 6 is in its initial state, the fan ring plate 10 is away from the gear 7. At this time, the two ends of the scraper 6 are respectively located at the mutually distant ends of the two arc-shaped plates 2 (i.e., Figure 3 The rear end of the curved plate on the left is far from the front end of the curved plate on the right, and close to the rear end of the curved plate on the right. Figure 3 For example, the left end of scraper 6 contacts the rear end of the left arc-shaped plate 2, and the right end of scraper 6 contacts the front end of the right arc-shaped plate 2. Scraper 6 is in its initial state. The left arc-shaped plate 2 and the front filter 3 form the first cavity, and the right arc-shaped plate 2 and the rear filter 3 form the second cavity. The outlet end of the air inlet pipe 12 is connected to the first cavity. When the front filter 3 needs to be replaced, motor 9 is started. Motor 9 drives fan ring plate 10 through the output shaft, causing fan ring plate 10 to rotate around the output shaft of the motor. The meshing gear on the fan ring plate rotates more than 90 degrees and less than 110 degrees, so that the two ends of scraper 6 slide in contact with the arc surfaces of the two filters 3 until they contact the arc surfaces of the two arc plates 2. At this point, the motor stops working, and the odor entering the cylinder passes through the scraper. The isolation at 6 can only be filtered through the rear filter 3. At this time, the front filter 3 can be replaced. When the rear filter 3 needs to be replaced, the motor 9 is restarted. As the fan ring plate rotates, the teeth on the fan ring plate disengage from the gear. Under the elastic force of the torsion spring 8, the scraper 6 rotates in the opposite direction. The two ends of the scraper 6 slide and contact the arc surfaces of the two filters 3 circumferentially until they contact the arc surfaces of the two arc plates 2. When the torsion spring 8 returns to its natural state and the fan ring plate returns to its initial state, the motor stops working. At this time, the rear filter 3 can be replaced. After the odor is initially filtered by the front or rear filter 3, it is filtered out through the filter 3 in the corresponding direction and enters the lower part of the box 1. After being treated by the biofilm 16, it is discharged through the exhaust pipe 13, completing the purification.

However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
