Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, specifically to a wastewater treatment reagent dosing device. Background Technology

[0002] Wastewater refers to the water discharged during residential activities and runoff rainwater. It includes domestic sewage, industrial wastewater and initial rainfall. In the wastewater treatment process, various agents need to be precisely added to the wastewater to remove pollutants and regulate water quality.

[0003] In current technologies, the addition of solid granular agents for wastewater treatment is mostly done manually by throwing the agents into the wastewater. The agents diffuse freely upon entry and react with the wastewater. However, manual throwing makes it difficult to control the placement of the agents, potentially leading to concentrated placement and prolonged diffusion, thus affecting the reaction rate. Therefore, a wastewater treatment agent dosing device is proposed to address these issues. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a wastewater treatment agent dosing device. This device allows for the movement and adjustment of the agent's dosing position, enabling more even distribution of the agent into the wastewater and thus accelerating the reaction rate between the agent and the wastewater. It solves the problem that in current technologies, the dosing of solid granular agents for wastewater treatment is mostly done manually by throwing the agent into the wastewater. While the agent diffuses freely upon entering the wastewater, it is difficult to control the position during manual dosing, which may result in concentrated dosing and prolonged diffusion, thus affecting the reaction rate between the agent and the wastewater.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A wastewater treatment agent dosing device includes a treatment tank. A reciprocating device is provided at the bottom of the treatment tank. Two support frames are fixedly connected to the outside of the reciprocating device, which are symmetrically distributed on the left and right sides and are slidably connected to the outside of the treatment tank. A telescopic rod is fixedly connected to the right side of the left support frame. An elastic device is provided on the left side of the right support frame. A screening frame is fixedly connected to the right side of the telescopic rod and to the left side of the elastic device. A screening basket is fixedly connected to the inside of the screening frame by fasteners. A second motor is fixedly connected to the outside of the left support frame. A reciprocating gear that is rotatably connected to the left support frame is fixedly connected to the outside of the output shaft of the second motor. A rack that meshes with the reciprocating gear is fixedly connected to the bottom of the screening frame.

[0008] The beneficial effects of this utility model are:

[0009] This wastewater treatment reagent dosing device has the advantage of being able to move and adjust the dosing position of the reagent, so that the reagent can be more evenly dosed into the wastewater, thereby accelerating the reaction rate between the reagent and the wastewater.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the reciprocating device includes a first motor fixedly connected to the outside of the processing box, and a reciprocating lead screw rotatably connected to the outside of the processing box is fixedly connected to the outside of the output shaft of the first motor. The outside of the reciprocating lead screw is connected by a threaded transmission block that is fixedly connected to the two support frames respectively.

[0013] Furthermore, sliding rods are fixedly connected to both the left and right sides of the processing box, and the interiors of the two support frames are slidably connected to the two sliding rods respectively.

[0014] The beneficial effect of adopting the above-mentioned further solution is that it can provide further support for the support frame and screening frame, and restrict their movement direction to prevent them from shifting or shaking.

[0015] Furthermore, the elastic device includes a plurality of springs fixedly connected to the right side of the screening frame, the right side of each of the plurality of springs being fixedly connected to the left side of the right side support frame, and a damper fixedly connected to the right side of the screening frame and fixedly connected to the left side of the right side support frame.

[0016] The beneficial effect of adopting the above-mentioned further solution is that it allows the screening frame to shake left and right, which facilitates the shaking of the agent and stabilizes the direction of shaking to prevent the agent from overflowing.

[0017] Furthermore, the screening frame has a threaded hole inside, and the screening basket has a bolt knob that is threadedly connected to the threaded hole inside. A handle is fixedly connected to the outside of the screening basket.

[0018] The advantage of adopting the above-mentioned further solution is that it facilitates the fixing and disassembly of the screening basket for cleaning and replacement, ensuring its proper functioning.

[0019] Furthermore, the screening basket is located above the processing box, and a number of baffles are fixedly connected inside the screening basket.

[0020] The beneficial effect of adopting the above-mentioned further scheme is that it enables the agent to be dispensed downward into the treatment box and allows the screening basket to be divided into areas to ensure the uniformity of agent dispensing in each position.

[0026] 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.

[0027] In the embodiments, by Figure 1-4The present invention discloses a wastewater treatment agent dosing device, comprising a treatment tank 1, a reciprocating device 2 at the bottom of the treatment tank 1, two support frames 3 symmetrically distributed and slidably connected to the outside of the reciprocating device 2, the right side of the left support frame 3 being fixedly connected to the right side, an elastic device 5 at the left side of the right support frame 3, a screening frame 6 fixedly connected to the right side of the telescopic rod 4 and the left side of the elastic device 5, a screening basket 7 fixedly connected inside the screening frame 6 by fasteners, a second motor 8 fixedly connected to the outside of the left support frame 3, a reciprocating gear 9 rotatably connected to the outside of the output shaft of the second motor 8, and a rack 10 meshing with the reciprocating gear 9 fixedly connected to the bottom of the screening frame 6.

[0028] The reciprocating device 2 includes a first motor 21 fixedly connected to the outside of the processing box 1. The output shaft of the first motor 21 is fixedly connected to a reciprocating lead screw 22 rotatably connected to the outside of the processing box 1. The outside of the reciprocating lead screw 22 is connected by a threaded transmission block 23, which is fixedly connected to two support frames 3 respectively.

[0029] In this embodiment, during actual use, the start of the first motor 21 will drive the reciprocating screw 22 to rotate, thereby causing the transmission block 23 to move along the direction of the screw under the action of the screw thread, and driving the two support frames 3 to move, so as to change the position of the screening basket 7 fixed thereto.

[0030] The processing box 1 is fixedly connected to sliding rods 11 on both the left and right sides, and the interiors of the two support frames 3 are slidably connected to the two sliding rods 11 respectively.

[0031] In this embodiment, during actual use, as the two support frames 3 move, they will also slide on the outside of the sliding rod 11. The sliding rod 11 restricts the direction of movement of the support frame 3 and further enhances the stability of the support frame 3, preventing damage to the reciprocating device 2 caused by the multiple components above it.

[0032] The elastic device 5 includes multiple springs 51 that are fixedly connected to the right side of the screening frame 6. The right side of each spring 51 is fixedly connected to the left side of the right support frame 3. The right side of the screening frame 6 is fixedly connected to a damper 52 that is fixedly connected to the left side of the right support frame 3.

[0033] In this embodiment, during actual use, the reciprocating gear 9 rotates under the drive of the second motor 8 and meshes with the rack 10. During the meshing process, the screening frame 6 moves horizontally and pulls the spring 51. Under the rebound of the spring 51, the medicine in the screening basket 7 shakes and leaks from the hole. The damper limits the time for the screening basket 7 to move left and right, so that it can quickly return to stillness and move again under the action of the reciprocating gear 9 and the rack 10.

[0034] The screening frame 6 has a threaded hole inside, the screening basket 7 has a bolt knob 12 that is threaded to the threaded hole inside, and a handle is fixedly connected to the outside of the screening basket 7.

[0035] In this embodiment, during actual use, the bolt knob 12 can be easily turned. By unscrewing the bolt knob 12, the sieve basket 7 can be removed from the sieve frame 6 for cleaning or replacement. This prevents the internal holes of the sieve basket 7 from becoming clogged or worn and deformed after long-term use, which would affect the leakage of the medicine.

[0036] The screening basket 7 is located above the processing box 1, and a number of baffles 13 are fixedly connected inside the screening basket 7.

[0037] In this embodiment, during actual use, the leaked medicine will fall into the processing box 1 below. Multiple baffles 13 can divide the sieve basket 7 into areas in the horizontal direction. The baffles 13 are low in height to prevent the medicine from accumulating on one side of the sieve basket 7 when there is less medicine and the sieve basket 7 bounces and shakes from side to side, thus causing uneven distribution of medicine.

[0038] Working principle:

[0039] When adding chemicals to the wastewater in treatment tank 1, the chemicals are first poured into the screening basket 7 of the screening frame 6. This process can be done manually or by controlling the stored chemicals to be poured into the screening basket 7 through an electronic valve. When adding chemicals, the first motor 21 is started, and the screening frame 6 moves back and forth. At this time, the second motor 8 is started, and the screening basket 7 will swing left and right under the meshing of gears, causing the chemicals in the screening basket 7 to fall through the holes into the treatment tank 1 below. By moving back and forth, the chemicals are added to different positions in the treatment tank 1 to ensure that the chemicals are added evenly.
