Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wastewater treatment, specifically relating to a filtration device for treating formaldehyde wastewater. Background Technology
[0002] Formaldehyde is an important industrial raw material, widely used in the production of chemicals, pharmaceuticals, wood preservatives, and adhesives. However, the production process often generates a certain amount of high-concentration formaldehyde wastewater. Because formaldehyde is highly toxic to humans and other organisms, if not properly treated, this formaldehyde wastewater will seriously pollute the environment, damage the ecosystem, and endanger human health.
[0003] Currently available formaldehyde wastewater filtration devices typically require cleaning of their internal filters after prolonged use. This cleaning process necessitates stopping the equipment and halting the wastewater treatment process before cleaning can begin. Furthermore, the filters gradually become clogged during use, reducing wastewater flow. These two factors combined negatively impact the efficiency of formaldehyde wastewater filtration. Therefore, this paper proposes a new formaldehyde wastewater filtration device to address these issues. Utility Model Content
[0004] In view of one or more of the above-mentioned defects or improvement needs of the prior art, the present invention provides a filtration device for treating formaldehyde wastewater.
[0005] To achieve the above objectives, this utility model provides a filtration device for treating formaldehyde wastewater, comprising two T-pipes, with valves connected to two ports of the T-pipes respectively, and connecting pipes connected to the other ports of the valves.
[0006] Two filter elements are respectively installed between the upper and lower connecting pipes to filter formaldehyde wastewater; the filter elements are equipped with cleaning components to clean impurities attached to the inside of the filter elements.
[0007] The power mechanism is located between the two filter elements and passes through the two cleaning elements. The power mechanism is connected to the two cleaning elements respectively and provides power to the two cleaning elements.
[0008] Furthermore, the filter element includes a cover and a tank, which are detachably connected by bolts. The cover is connected to an upper connecting pipe, and the tank is connected to a lower connecting pipe. A support ring is disposed inside the tank. A filter bucket is detachably disposed on the support ring by bolts.
[0009] Furthermore, the cleaning components include a rotating rod rotatably mounted inside the filter barrel, with one end of the rotating rod penetrating the filter barrel and sealing it with the filter barrel via a sealed bearing; a crown gear mounted on the bottom end of the rotating rod; and a cleaning brush mounted on the outer wall of the rotating rod for scrubbing the inner wall of the filter barrel.
[0010] Furthermore, the power mechanism includes a mounting plate disposed between the two tanks; a dual-head servo motor disposed on the mounting plate; two transmission rods respectively disposed on the two output ends of the dual-head servo motors, one end of the transmission rod passing through the tank and rotating in cooperation with the tank, and the transmission rods achieving a seal with the tank through sealed bearings; and two gears respectively disposed on opposite ends of the two transmission rods, the gears meshing with crown gears.
[0011] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:
[0012] (1) The filter device for treating formaldehyde wastewater of this utility model can improve the filtration efficiency by increasing the number of filter components through the two filter elements. When cleaning is required, two valves on one side can be closed to clean one filter element while the other filter element remains in working condition. Thus, cleaning or maintenance can be carried out without stopping the equipment, thereby further improving the efficiency during use.
[0013] (2) The filter device for treating formaldehyde wastewater of this utility model can also drive two cleaning components to clean two filter components at the same time during normal use of the equipment, so as to avoid the filter components from becoming clogged during use, thereby reducing the wastewater flow and affecting efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-3 The filtration device for treating formaldehyde wastewater in this embodiment not only improves filtration efficiency by increasing the number of filter components through the two filter elements 4, but also allows for the closure of two valves 2 on one side when cleaning is required, cleaning one filter element 4 while the other filter element 4 remains operational. This eliminates the need to stop the equipment from use for cleaning or maintenance, further improving efficiency. Furthermore, the power mechanism 6 can drive the two cleaning components 5 to clean both filter elements 4 simultaneously during normal operation, minimizing the risk of clogging and reducing wastewater flow, thus improving efficiency.
[0020] Specifically, it includes two T-pipes 1, with valves 2 connected to two ports of each T-pipe 1, and a connecting pipe 3 connected to the other port of each valve 2.
[0021] Two filter elements 4 are respectively installed between the upper and lower connecting pipes 3 for filtering formaldehyde wastewater; a cleaning element 5 is installed inside the filter element 4 for cleaning impurities attached inside the filter element 4.
[0022] The power mechanism 6 is located between the two filter elements 4 and passes through the two cleaning elements 5. The power mechanism 6 is connected to the two cleaning elements 5 respectively and provides power to the two cleaning elements 5.
[0023] In this embodiment, when needed, the remaining ports of the two T-pipes 1 can be connected to the external water supply pipe and outlet pipe respectively, and all valves 2 can be opened. When external wastewater enters the device through the upper T-pipe 1, it will pass through the upper two connecting pipes 3 and enter the two filter elements 4 for treatment. The filter elements 4 can intercept impurities in the wastewater, thereby filtering the wastewater. After treatment, it can be discharged through the lower connecting pipe 3 and T-pipe 1 to complete the wastewater treatment process. The two filter elements 4 not only increase the filtration efficiency by increasing the number of filter components, but also, when cleaning is required, the two valves 2 on one side can be closed to clean one filter element 4, while the other filter element 4 remains in working condition. Thus, cleaning or maintenance can be performed without stopping the equipment, thereby further improving the efficiency during use. The power mechanism 6 can also drive the two cleaning elements 5 to clean the two filter elements 4 simultaneously during normal use of the equipment, so as to avoid the filter elements 4 from becoming clogged during use, which would reduce the wastewater flow and affect efficiency.
[0024] Specifically, refer to Figure 2-3 The filter element 4 includes a cover 41 and a tank 42. The cover 41 and the tank 42 are detachably connected by bolts. The cover 41 is connected to the upper connecting pipe 3, and the tank 42 is connected to the lower connecting pipe 3. A bearing ring 43 is disposed inside the tank 42. A filter bucket 44 is detachably disposed on the bearing ring 43 by bolts.
[0025] In this embodiment, when formaldehyde wastewater enters the tank 42, it passes through the filter bucket 44 under the influence of water flow. The filter bucket 44 can screen out the impurities remaining in the wastewater, thereby completing the wastewater treatment process.
[0026] Specifically, refer to Figure 2-3 The cleaning component 5 includes a rotating rod 51, which is rotatably disposed inside the filter barrel 44. One end of the rotating rod 51 passes through the filter barrel 44 and is sealed to the filter barrel 44 through a sealed bearing. A crown gear 52 is disposed at the bottom end of the rotating rod 51. A cleaning brush 53 is disposed on the outer wall of the rotating rod 51 for brushing the inner wall of the filter barrel 44.
[0027] Specifically, refer to Figure 2-3 The power mechanism 6 includes a mounting plate 61 disposed between two tanks 42; a dual-head servo motor 62 disposed on the mounting plate 61; two transmission rods 63 respectively disposed on the two output ends of the dual-head servo motor 62, the transmission rods 63 being detachably connected to the dual-head servo motor 62 via a coupling, one end of the transmission rod 63 passing through the tank 42 and rotating in cooperation with the tank 42, the transmission rods 63 being sealed to the tank 42 via a sealed bearing; and two gears 64 respectively disposed on opposite ends of the two transmission rods 63, the gears 64 meshing with a crown gear 52.
[0028] In this embodiment, when the dual-head servo motor 62 is powered on, the two transmission rods 63 drive the two crown gears 52 to rotate through the gears 64 respectively. The crown gears 52 will drive the rotating rod 51 and the cleaning brush 53 to rotate in sequence and brush the inner wall of the filter barrel 44, thereby avoiding the filter barrel 44 from clogging during use, which would reduce the wastewater flow and affect efficiency.
