Description

Technical Field

[0001] This application relates to the field of chemical dosing mechanisms, and more specifically, to a wastewater treatment chemical dosing mechanism. Background Technology

[0002] In the field of wastewater treatment, chemical solutions are usually added to wastewater through dosing equipment, so that the chemical solutions react with the harmful substances in the wastewater and the wastewater is purified.

[0003] Currently, in wastewater treatment, most conventional chemical solutions are made by mixing solid agents with water. For example, in the flocculation and sedimentation treatment of wastewater, polyaluminum chloride powder is dissolved in water to prepare a 5%-10% aqueous solution, which is then added to the wastewater to remove suspended solids. However, in actual use, polyaluminum chloride powder easily absorbs moisture from the air, causing it to clump. Therefore, when dissolving it to prepare an aqueous solution, adding this type of solid agent to the dosing equipment and dissolving it in the water in the equipment requires a long stirring time to ensure dissolution, thus prolonging the stirring time and making the preparation of the solution inconvenient. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this application is to provide a wastewater treatment dosing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: A wastewater treatment dosing mechanism includes a tank and a tank cover. The tank has a cavity with an opening at the top. The tank cover is detachably installed at the opening of the cavity. The cavity is provided with a crushing component, a dispersing component and a stirring component from top to bottom. The crushing assembly includes a crushing cylinder mounted on a tank cover, a feed hopper connected to the inside of the crushing cylinder on the tank cover, a screen embedded at the bottom of the crushing cylinder, and a crushing component inside the crushing cylinder. The dispersion assembly includes a dispersion plate detachably disposed in the cavity, with leakage holes distributed along the circumference of the tank body on the dispersion plate. The dispersion assembly also includes a rotating shaft rotatably disposed on the tank cover, with a scraper on the rotating shaft for scraping the dispersion plate.

[0006] Furthermore, a guide groove is formed by a downward indentation on the dispersing plate. The guide groove is annular and arranged around the circumference of the dispersing plate. The leakage holes are distributed on the bottom wall of the guide groove. The two side walls of the guide groove are inclined to form a guide surface.

[0007] Furthermore, the outer peripheral sidewall of the dispersion plate extends downward to form a mounting ring, which is fixedly mounted to the sidewall of the cavity by bolts.

[0008] Furthermore, the rotating shaft extends through the dispersion plate to the bottom of the cavity, and the stirring assembly includes a stirring rod located at the bottom of the rotating shaft.

[0009] Furthermore, the can lid is equipped with a first motor for driving the rotating shaft.

[0010] Furthermore, the crushing component includes a crushing shaft rotatably disposed within the crushing cylinder, and the crushing shaft is provided with crushing blades.

[0011] Furthermore, a second motor is provided on the tank lid for driving the crushing shaft to rotate.

[0012] Furthermore, a dosing pipe is installed at the bottom of the tank via a metering pump.

[0013] Compared with the prior art, the beneficial effects of this application are: 1. In this application, the solid drug is crushed by the crushing component, which can prevent the solid drug from clumping. The crushed drug powder is dispersed and added to the bottom of the cavity by the dispersing component, which avoids the drug powder being concentrated at the bottom of the cavity, thus prolonging the subsequent stirring and dissolution time. The drug powder and water at the bottom of the cavity are stirred by the stirring component to promote the dissolution of the powder and realize the preparation of chemical solution.

[0014] This application, through the setting of a metering pump and a dosing pipe, allows the chemical reagents prepared at the bottom of the tank to be quantitatively added to the wastewater to be treated through the dosing pipe, thereby completing the dosing in wastewater treatment.

[0021] To further understand the content of this application, a detailed description of this application will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative and not intended to limit the scope of this application.

[0022] The following is in conjunction with the appendix Figures 1-5 This embodiment will be described in further detail.

[0023] like Figures 1-2 As shown in this embodiment, a wastewater treatment dosing mechanism is capable of mixing solid reagents with water to prepare a chemical solution used in wastewater treatment, and adding the prepared chemical solution to the wastewater to be treated.

[0024] It includes a tank body 100 and a tank cover 110. The tank body 100 has a cavity with an opening at the top. The tank cover 110 is detachably installed at the opening of the cavity. The cavity is provided with a crushing component, a dispersing component and a stirring component from top to bottom. In this embodiment, the solid medicine is crushed by the crushing component, which can prevent the solid medicine from clumping and thus prolong the subsequent stirring and dissolving time. The dispersion component allows the crushed powder to be added dispersedly to the bottom of the cavity, preventing the powder from being concentrated at the bottom of the cavity and thus prolonging the subsequent stirring and dissolving time. The stirring component allows for the mixing of the powder and water added to the bottom of the cavity, promoting powder dissolution and enabling the preparation of the chemical solution.

[0025] Combination Figures 3-5As shown, in this embodiment, the crushing component includes a crushing cylinder 210 disposed on the can lid 110. The can lid 110 is provided with a feed hopper 140 communicating with the inside of the crushing cylinder 210. A screen 211 is embedded at the bottom of the crushing cylinder 210. Specifically, the upper end of the crushing cylinder 210 is fixedly installed on the lower side of the can lid 110, and the lower end of the crushing cylinder 210 is provided with a discharge port. The screen 211 is embedded in the discharge port. A crushing component is provided inside the crushing cylinder 210. Thus, in actual use, the solid medicine to be crushed is added into the crushing cylinder 210 through the feed hopper 140. After being crushed by the crushing component, medicine powder is produced. The medicine powder is discharged through the screen 211 and enters the dispersion component below it.

[0026] The dispersion component includes a dispersion plate 240 that is detachably disposed in the cavity. The dispersion plate 240 has leakage holes 513 distributed around the tank body 100. The dispersion component also includes a rotating shaft 230 that is rotatably disposed on the tank cover 110. The rotating shaft 230 is provided with a scraper 232 for scraping the dispersion plate 240.

[0027] In this embodiment, the powder falls onto the dispersing plate 240. At this time, the scraper 232 is driven to rotate on the upper surface of the dispersing plate 240 by the rotating shaft 230. This can drive the powder to fall through the holes 513 at different positions into the cavity below, so as to achieve the dispersion of the powder and avoid the problem of concentration. In this embodiment, to ensure that the powder falling onto the dispersing plate 240 can be more comprehensively added into the cavity below, a guide groove 511 is formed by a downward indentation on the dispersing plate 240 below the sieve 211. The guide groove 511 is annular and arranged circumferentially along the dispersing plate 240. The drain holes 513 are distributed on the bottom wall of the guide groove 511. The two side walls of the guide groove 511 are inclined to form a guide surface, so that the powder falling from the sieve 211 can slide along the guide surface to the bottom wall of the guide groove 511. The scraper 232 is also bent so that it can slide and fit against the side wall of the guide groove 511. At this time, the scraper 232 is rotated by the rotating shaft 230, which can scrape the powder in the guide groove 511 and add it into the cavity below through the drain holes 513 at different positions.

[0028] Specifically, in order to achieve the rotation of the rotating shaft 230, in this embodiment, the can lid 110 is provided with a first motor 130 for driving the rotating shaft 230 to rotate.

[0029] In this embodiment, in order to achieve detachable installation of the can lid 110 at the upper opening of the can body 100, a fixing part 111 is provided extending downward on the outer side wall of the can lid 110. The fixing part 111 cooperates with the outer side wall of the can body 100 and is fixedly installed on the outer side wall of the can body 100 by bolts to achieve detachable connection.

[0030] In actual use, in order to facilitate the assembly and disassembly of the crushing component, dispersing component and stirring component in the cavity along with the tank cover 110, in this embodiment, the outer peripheral sidewall of the dispersing plate 240 extends downward to form an mounting ring 512, which is fixedly mounted on the sidewall of the cavity by bolts.

[0031] In this embodiment, the rotating shaft 230 extends through the dispersion plate 240 to the bottom of the cavity, and the stirring assembly includes a stirring rod 231 disposed at the bottom of the rotating shaft 230.

[0032] Specifically, the outer wall of the tank 100 is provided with a water injection pipe 101 for adding water into the cavity, and the water injection pipe 101 is located below the dispersion plate 240. The rotating shaft 230 drives the stirring rod 231 to stir the water at the bottom of the cavity and the medicine powder added to the water, so that the medicine powder dissolves in the water and the chemical solution is prepared.

[0033] In this embodiment, the pulverizing component includes a pulverizing shaft 220 rotatably disposed inside the pulverizing cylinder 210. The pulverizing shaft 220 is provided with a pulverizing blade 221. The pulverizing shaft 220 rotates to drive the pulverizing blade 221 to rotate, thereby pulverizing the solid medicine added to the pulverizing cylinder 210 to prepare medicine powder.

[0034] In order to enable the crushing shaft 220 to rotate, the tank cover 110 is equipped with a second motor 150 for driving the crushing shaft 220 to rotate.

[0035] In this embodiment, a dosing pipe 121 is provided at the bottom of the tank 100 via a metering pump 120. Therefore, under the action of the metering pump 120, the chemical agent prepared at the bottom of the tank 100 can be quantitatively added to the wastewater to be treated through the dosing pipe 121 to complete the dosing in wastewater treatment.

[0036] In this embodiment, in order to install the metering pump 120 and the dosing pipe 121 at the bottom of the tank 100, a support leg 102 is provided at the bottom of the tank 100. The support leg 102 is used to suspend the bottom of the tank 100 so that the metering pump 120 and the dosing pipe 121 can be installed.

[0037] In summary, the above description is only a preferred embodiment of this application. All equivalent changes and modifications made within the scope of this application should be covered by this application.
