Description

Technical Field

[0001] This utility model belongs to the field of synergistic purification technology of industrial waste salt and fly ash washing liquid, and in particular relates to a synergistic purification device for industrial waste salt and fly ash washing liquid. Background Technology

[0002] Industrial waste salt is a solid waste mainly composed of inorganic salts, generated during industrial production and high-salt wastewater treatment. It contains a large amount of inorganic salts and organic pollutants. Fly ash washing liquid is generated during the fly ash washing process of waste incineration. It is a typical high-concentration inorganic high-salt wastewater, characterized by high salt, high calcium, high pH value, heavy metals, and suspended solids. Synergistic purification of both can effectively achieve resource recycling and environmental protection. The current common purification process involves first mixing industrial waste salt with fly ash washing liquid to allow the substances to react fully, followed by solid-liquid separation. The separated solution is then further purified through heating, electrolysis, and other processes. However, existing separation devices struggle to remove the intercepted solid waste in a timely manner during operation. Over time, the solid waste accumulates, easily clogging internal pipes and filter components, affecting separation efficiency, reducing the operational stability of the entire co-purification device, increasing maintenance costs and downtime, and severely hindering the efficient implementation of co-purification of industrial waste salt and fly ash washing liquid. Utility Model Content

[0003] The purpose of this invention is to provide a co-purification device for industrial waste salt and fly ash washing liquid. This device features a separation mechanism. Specifically, after the waste salt solution and fly ash washing liquid are mixed and stirred, they fall from the reaction tank onto a separation plate in a separation tank. A motor drives a reciprocating screw to rotate. The rotation of the reciprocating screw moves an internal threaded block, which in turn moves a rack. Through rack and gear transmission, a scraper reciprocates along the arc-shaped separation plate, thus promptly removing solid waste from the separation plate and preventing its accumulation and blockage of the separation pores. This allows the liquid purification product to flow quickly and stably through the pores of the separation plate into the bottom of the separation tank for discharge, ensuring efficient and thorough solid-liquid separation. This provides pure liquid raw materials for subsequent processing, guarantees the stable operation of the overall purification process, and solves the problem that existing separation devices struggle to promptly remove intercepted solid waste during operation.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a co-purification device for industrial waste salt and fly ash washing liquid, comprising a support frame, a reaction tank fixedly connected to the inner wall of the support frame, a separation box fixedly connected to the support frame, a feed inlet fixedly connected to the top of the reaction tank, a connecting pipe fixedly connected to the bottom of the reaction tank, the bottom end of the connecting pipe fixedly connected to the separation box, and a valve fixedly connected to the outer wall of the connecting pipe, and further comprising: A separation mechanism, mounted on a separation tank, is used to separate the purified solid and liquid phases; and A reaction mechanism is installed on a reaction tank, and the reaction mechanism is used to cause a reaction between the waste salt solution and the fly ash washing liquid to remove residual pollutants; In this process, a certain proportion of waste salt solution and fly ash washing liquid are fed into the reaction tank through the inlet. The reaction mechanism allows the two products to interact and work together to purify the waste salt solution and fly ash washing liquid, further removing pollutants from them. Finally, the solid and liquid are separated by the separation mechanism.

[0008] Furthermore, the drive assembly includes a motor mounted on a support frame, the output shaft of the motor being fixedly connected to a reciprocating lead screw via a coupling, an internal thread block being slidably connected to the outer wall of the reciprocating lead screw, a limit rod being fixedly connected to the support frame, and the internal thread block being slidably connected to the limit rod. The internal thread block is limited by a limiting rod.

[0009] Furthermore, the transmission assembly includes a rack fixedly connected to the bottom of the internal thread block, and a gear fixedly connected to the outer wall of the rotating shaft, wherein the rack meshes with the gear; When the internal threaded block moves, it drives the rack to move, and when the rack moves, it drives the gear to rotate. This, in turn, drives the rotating shaft to rotate, which in turn drives the scraper to scrape off the solid waste on the surface of the separation plate.

[0010] Furthermore, the mixing assembly includes a second motor mounted on the top of the reaction vessel, the output shaft of the second motor being fixedly connected to a second rotating shaft via a coupling, and a plurality of stirring blades being fixedly connected to the outer wall of the second rotating shaft; Among them, motor 2 is connected to the reaction vessel by bolts.

[0021] The reaction mechanism 3 includes a mixing component 31, which is mounted on the reaction tank 11. The mixing component 31 is used to mix and stir the waste salt solution and the fly ash washing liquid; and The turbulence-disrupting component 32 is installed inside the reaction tank 11 and is used to turbulent the waste salt solution and fly ash washing liquid.

[0022] The waste scraping assembly 21 includes a separation plate 211 fixedly connected to the inner wall of the separation box 12, a rotating shaft 212 passing through the separation box 12 and rotatably connected to the separation box 12, and a scraper 213 fixedly connected to the outer wall of the rotating shaft 212 and slidably connected to the separation plate 211; and The left and right sides of the separation box 12 are respectively provided with through slots 214, the left and right sides of the separation box 12 are respectively fixedly connected with guide plates 215, and the bottom of the separation box 12 is fixedly connected with a drain pipe 216. The distance from the center of the rotating shaft 212 to the side that contacts the scraper 213 is the same as the radius of the separating plate 211.

[0023] The drive assembly 22 includes a motor 221 mounted on the support frame 1. The output shaft of the motor 221 is fixedly connected to a reciprocating lead screw 222 via a coupling. An internal thread block 223 is slidably connected to the outer wall of the reciprocating lead screw 222. A limit rod 224 is fixedly connected to the support frame 1.

[0024] The transmission assembly 23 includes a rack 231 fixedly connected to the bottom of the internal thread block 223, and a gear 232 fixedly connected to the outer wall of the rotating shaft 212, with the rack 231 meshing with the gear 232; Among them, gear 232 is fixedly connected to shaft 212 by welding.

[0025] The mixing assembly 31 includes a second motor 311 mounted on the top of the reaction vessel 11.

[0027] A specific application of this embodiment is as follows: When using this device, firstly, waste salt solution and fly ash washing liquid, along with auxiliary pharmaceutical solution, are added to the reaction tank 11 through the feed inlet 111. Then, motor 311 is started, driving shaft 312 to rotate, causing the two sets of stirring blades 313 distributed vertically to stir the liquid at high speed, promoting thorough mixing. At this time, the liquid forms a circulation under the action of the stirring blades 313, colliding with the baffles 321 and baffle columns 322 fixed on the inner wall of the reaction tank 11, disrupting the liquid streamlines and generating turbulent eddies. This turbulence... The effect further increases the probability of contact between pollutants such as heavy metal ions and organic matter in the waste salt solution and fly ash washing liquid, while accelerating the diffusion of auxiliary agents. For example, hydroxide ions in fly ash washing liquid and heavy metal ions in waste salt solution react rapidly under thorough mixing and turbulence to generate hydroxide precipitates; organic matter is degraded under the action of oxidant. The turbulence plate 321 and turbulence column 322 can also prolong the residence time of liquid in reaction tank 11 to ensure a more thorough reaction, and ultimately effectively remove pollutants such as organic matter and heavy metals from the solution, achieving synergistic purification.

[0028] After the waste salt solution and fly ash washing liquid in the reaction tank 11 have completed their synergistic reaction, the valve 113 is opened, and the solid-liquid mixture flows into the separation tank 12 through the connecting pipe 112 and falls onto the arc-shaped separation plate 211. At this time, the motor 221 is started, driving the reciprocating screw 222 to rotate, causing the internal thread block 223 to slide back and forth on the limit rod 224. The internal thread block 223 drives the rack 231 to move synchronously. The rack 231 meshes with the gear 232, driving the gear 232 to drive the rotating shaft 212 to rotate, causing the scraper 213 fixed on the rotating shaft 212 to scrape back and forth along the surface of the separation plate 211. The solid waste is scraped by the scraper 213 to the through grooves 214 on both sides of the separation tank 12 and discharged through the guide plate 215, while the liquid falls into the bottom of the separation tank 12 through the holes of the separation plate 211 and flows out through the drain pipe 216, realizing solid-liquid separation and ensuring that the purified liquid does not contain solid impurities, providing pure raw materials for subsequent processing.
