Description

Technical Field

[0001] This utility model relates to the field of wastewater pretreatment technology, specifically a multidimensional catalytic oxidation wastewater pretreatment device. Background Technology

[0002] Wastewater pretreatment is a pre-treatment facility set up before wastewater enters traditional sedimentation, biological, and other treatment processes, based on the water quality requirements of subsequent treatment flows. It is the "choke point" of a wastewater treatment plant. For centralized urban wastewater treatment plants and decentralized wastewater treatment plants within pollution sources, pretreatment mainly includes treatment facilities such as screens, grit chambers, and sand separators. However, for certain industrial wastewater, in addition to the general pretreatment mentioned above, water quality and quantity adjustment and other special pretreatment are required before entering centralized or decentralized wastewater treatment plants, such as neutralization, screening, pre-sedimentation, and pre-aeration. If the pretreatment process is substandard, resulting in excessive screenings, it will cause significant wear and tear on subsequent treatment equipment.

[0003] In the prior art, a multidimensional catalytic oxidation high-concentration wastewater pretreatment device with authorization announcement number CN216537133U relates to the field of wastewater treatment equipment technology. It includes a pretreatment tank body. The front and rear surface walls of the pretreatment tank body are provided with track mounting plates near the top edge in the horizontal direction. Filter plate tracks are provided at the top center of the two track mounting plates. A filter device is slidably arranged between the two filter plate tracks. The filter device includes a filter slide plate body. The bottom of the filter slide plate body is provided with mating grooves near the edges of the front and rear surfaces.

[0004] While the above-mentioned solution offers numerous advantages, it also suffers from the following drawbacks: The device utilizes two secondary filter plates on the filter slide body for alternating filtration of wastewater. The movement of both the filter slide body and the secondary filter plates requires multiple driving devices such as cylinders, or manual operation steps by personnel to complete the movement of the filter slide body and the cleaning of the secondary filter plates. This increases the operating cost of the multidimensional catalytic oxidation wastewater pretreatment device and makes its use cumbersome. Utility Model Content

[0005] The purpose of this invention is to provide a multidimensional catalytic oxidation wastewater pretreatment device to solve the problem of the cumbersome use of existing multidimensional catalytic oxidation wastewater pretreatment devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multidimensional catalytic oxidation wastewater pretreatment device, comprising a tank body, a filter slide body slidably disposed on the upper part of the tank body, a through-type filter port opened on the upper part of the filter slide body, shafts rotatably connected to both sides of the filter slide body located at the upper opening of the filter port, a first filter plate fixedly sleeved on the outer side of the shafts, two racks fixedly connected to the tank body, a large gear being driven on one side of the racks, the large gear being rotatably disposed on the filter slide body, and a transmission component being driven between the large gear and the end of the shaft.

[0007] Preferably, the transmission assembly includes a pinion, a worm gear, and a worm shaft rotatably connected to the filter slide body. The worm gear is fixedly connected to the end of the shaft, and the end of the worm shaft is fixedly connected to the center of the upper part of the pinion. The pinion meshes with the large gear, and the outer diameter of the pinion is smaller than the outer diameter of the large gear.

[0008] Preferably, a turntable is fixedly sleeved at the end of the shaft, and a slot is provided on one side of the turntable. A fixing block is installed on the upper part of the filter slide body, and a pin groove is provided on one side of the fixing block. A pin is slidably arranged in the pin groove. One end of the pin is a round pin head, and a spring is provided between the other end of the pin and the inner wall of the pin groove. The pin head on the pin cooperates with the slot.

[0009] Preferably, two track grooves are provided on one side of the filter slide body, and a track rod is slidably arranged in the cavity of the track groove. The track rod is fixed to the upper part of the pool body, and the vertical cross section of the track rod is a convex-shaped structure, and the vertical cross section of the track groove is a convex-shaped cavity.

[0010] Preferably, the filter outlet includes a drop opening, and a placement groove is formed at the upper opening of the drop opening, in which a second filter plate is placed.

[0011] Preferably, the filter slide body has placement slots on both sides, and a collection box with a top opening is placed in the placement slot.

[0012] Preferably, a first filter hole is provided on the bottom wall inside the collection box, and a plurality of second filter holes are provided on the bottom wall inside the placement trough.

[0025] 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.

[0026] Example: Figure 1 - Figure 7 As shown, this utility model provides a technical solution for a multidimensional catalytic oxidation wastewater pretreatment device, including a tank body 1. A filter slide body 2 is slidably arranged on the upper part of the tank body 1. A through-type filter port 3 is opened on the upper part of the filter slide body 2. Shafts 8 are rotatably connected to both sides of the upper opening of the filter port 3 on the filter slide body 2. A first filter plate 4 is fixedly sleeved on the outside of the shafts 8. Two racks 5 are fixedly connected to the tank body 1. A large gear 6 is driven on one side of the racks 5. The large gear 6 is rotatably arranged on the filter slide body 2, and a transmission component 7 is driven between the large gear 6 and the end of the shaft 8.

[0027] The first filter plate 4, as the first device for filtering wastewater in the apparatus, will intercept the residue in the wastewater. When the residue accumulates to a certain extent, it can be cleaned by flipping the first filter plate 4. Since the filter slide plate body 2 can slide along the track rod 14, when one of the first filter plates 4 is being cleaned, the other first filter plate 4 will continue to perform the filtering function.

[0028] like Figure 7 As shown, the transmission assembly 7 includes a pinion 703, a worm gear 701, and a worm 702, all rotatably connected to the filter slide body 2. The worm gear 701 is fixedly connected to the end of the shaft 8, and the end of the worm 702 is fixedly connected to the shaft center of the upper part of the pinion 703. The pinion 703 meshes with the large gear 6, and the outer diameter of the pinion 703 is smaller than the outer diameter of the large gear 6.

[0029] When the filter slide body 2 is moved, the filter slide body 2 passes through the rack and pinion 5, which drives the large gear 6 to rotate. The large gear 6 then drives the worm gear 702 to rotate through the small gear 703. The worm gear 702 then drives the shaft 8 to rotate through the worm wheel 701. The shaft 8 then drives the corresponding first filter plate 4 to rotate, and the first filter plate 4 can be flipped.

[0030] The self-locking effect of the worm gear 701 and worm 702 is used to improve the stability of the first filter plate 4 and prevent the first filter plate 4 from rotating.

[0031] like Figure 1 , Figure 6 and Figure 7As shown, a turntable 9 is fixedly sleeved at the end of the shaft 8, and a slot 10 is opened on one side of the turntable 9. A fixing block is installed on the upper part of the filter slide body 2, and a pin groove 11 is opened on one side of the fixing block. A pin rod 12 is slidably arranged in the pin groove 11. One end of the pin rod 12 is a round pin head, and a spring is provided between the other end of the pin rod 12 and the inner wall of the pin groove 11. The pin head on the pin rod 12 cooperates with the slot 10.

[0032] When the first filter plate 4 is parallel to the filter slide body 2 and is attached to the upper part of the filter slide body 2, the slot 10 on the turntable 9 is aligned with the slot of the pin groove 11. The spring force is used to pop out the head of the pin rod 12 and insert the head of the pin rod 12 into the cavity of the slot 10. This increases the friction of the turntable 9 and makes the shaft 8 unable to rotate easily.

[0033] like Figure 1 - Figure 3 As shown, two track grooves 13 are opened on one side of the filter slide body 2. Track rods 14 are slidably arranged in the cavity of the track grooves 13. The track rods 14 are fixed to the upper part of the pool body 1. The vertical cross section of the track rods 14 is a convex structure, and the vertical cross section of the track grooves 13 is a convex cavity.

[0034] like Figure 4 As shown, the filter port 3 includes a drop opening 301, and a placement groove 302 is formed at the upper opening of the drop opening 301. A second filter plate 15 is placed in the placement groove 302.

[0035] like Figure 1 , Figure 3 and Figure 4 As shown, both sides of the filter slide body 2 are provided with placement slots 17, and a collection box 18 with a top opening is placed in the placement slot 17.

[0036] Collection box 18 is used to collect the waste residue and waste material dumped out by the first filter plate 4 after it is flipped over;

[0037] The first and second filter holes provided in the collection box 18 and the placement tank 17 are for the purpose of facilitating the discharge of liquid from the collection box 18 and preventing liquid from occupying the internal space of the collection box 18. The aperture of the first and second filter holes is smaller than the aperture of the filter holes on the first filter plate 4 and the second filter plate 15.

[0038] like Figure 1 , Figure 3 and Figure 4 As shown, a first filter hole is provided on the bottom wall inside the collection box 18, and a plurality of second filter holes are provided on the bottom wall inside the placement slot 17.

[0039] like Figure 1 and Figure 2As shown, a wastewater discharge pipe 20 is fixedly connected to one side of the pool body 1, and a pipe support frame 16 is installed on the outer wall of the other side of the pool body 1. A wastewater input pipe 19 is supported on the pipe support frame 16.

[0040] The pipe support frame 16 supports the wastewater inlet pipe 19. Wastewater enters the tank 1 through the outlet of the wastewater inlet pipe 19. When the next pretreatment begins, the wastewater is discharged through the wastewater outlet pipe 20.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
