Description

Technical Field

[0001] This utility model relates to the field of extraction box technology, specifically a multi-stage extraction box with an inclined discharge bottom. Background Technology

[0002] Multistage extraction is a unit operation widely used in chemical, hydrometallurgical, pharmaceutical and environmental protection fields to separate and purify target components. In multistage extraction processes, the extraction chamber usually contains multiple mixing chambers and clarification chambers connected in series or parallel. The material flows between each stage to complete the mass transfer and separation process. To ensure smooth material transfer between stages and achieve efficient separation, the bottom of the clarification chamber is usually set with an inclined structure, using gravity to collect the heavy phase or solid residue along the inclined surface to the discharge port, thereby achieving continuous discharge.

[0003] Traditional multi-stage extraction chambers use an integral, fixed-angle discharge bottom structure. Each chamber shares the same tilt angle, which is difficult to adjust independently. Due to differences in the viscosity, solid content, and reaction progress of materials in different chambers, a uniform, fixed tilt angle is difficult to match the actual flow characteristics of materials at each stage. If the tilt angle is too small, high-viscosity or high-solids-content materials will not be discharged smoothly, causing stagnation and blockage. If the tilt angle is too large, low-viscosity materials will be discharged too quickly, shortening the clarification time and reducing the extraction efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a multi-stage extraction box with an inclined discharge bottom, which solves the problem of traditional multi-stage extraction boxes using an integral fixed-angle discharge bottom structure. Each chamber shares the same tilt angle and cannot be adjusted independently. Due to differences in the viscosity, solid content, and reaction progress of materials in different chambers, a uniform fixed tilt angle cannot match the actual flow characteristics of materials at each stage. If the tilt angle is too small, high-viscosity or high-solid-content materials will not be discharged smoothly, causing stagnation and blockage; if the tilt angle is too large, low-viscosity materials will be discharged too quickly, shortening the clarification time and reducing the extraction efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a multi-stage extraction box with an inclined discharge bottom, comprising a box body. Two partitions are fixedly installed on the inner wall of the box body, dividing the interior of the box body into three chambers. Three discharge pipes are fixedly installed on the front side of the box body, and the three discharge pipes are respectively connected to the three chambers. Three sets of adjustable material guiding mechanisms that can adjust the angle of the bottom discharge plate are installed inside the box body, and the three sets of adjustable material guiding mechanisms are respectively installed inside the three chambers. Three sewage pipes are fixedly installed on the lower surface of the box body, and the three sewage pipes are respectively connected to the interior of the three chambers.

[0007] Furthermore, the adjustable material guiding mechanism includes a mounting frame, which is fixedly installed on the lower surface of the box. A first motor is fixedly installed on the inner bottom of the mounting frame, and a screw is fixedly installed on the output end of the first motor. A threaded tube is threadedly connected to the outer surface of the screw, and the threaded tube is slidably connected to the inner wall of the box and extends into the interior of the chamber.

[0008] Furthermore, an installation plate is fixedly installed at one end of the threaded tube, and sliding grooves are provided on both sides of the installation plate. A slider is slidably connected inside the sliding groove, and a spring is fixedly installed on the inner wall of the sliding groove. One end of the spring is fixedly connected to the outer surface of the slider.

[0009] Furthermore, a connecting plate is fixedly installed on one side of each slider, and an abutment wheel is rotatably connected to one end of each of the two connecting plates.

[0010] Furthermore, each of the chambers is provided with a guide plate inside, and a rotating shaft is fixedly installed on both sides of one end of the guide plate. The rotating shaft and the partition are rotatably connected to the inner wall of the box. The lower surface of the end of the guide plate away from the rotating shaft abuts against the outer surface of the abutting wheel.

[0011] Furthermore, a second motor is fixedly installed on one side of one of the connecting plates.

[0012] Furthermore, an eccentric wheel is fixedly installed at the output end of the second motor.

[0013] This utility model has the following beneficial effects:

[0014] (1) By independently setting up lifting drive components consisting of a first motor, screw and threaded tube in each chamber, the operator can adjust the tilt angle of the guide plate according to the viscosity, solid content and reaction progress of the material in different chambers. This structure allows each stage of the multi-stage extraction box to independently match the best discharge slope during the step-by-step processing, avoiding the problem of discharge being too fast or too slow due to a uniform tilt angle, and significantly improving the control accuracy and adaptability of the multi-stage extraction process.

[0015] (2) The present invention provides an eccentric wheel driven by a second motor in the adjustable material guiding mechanism, which, together with the slider, the groove and the spring, forms an elastic vibration structure, so that the abutting wheel generates continuous micro-amplitude vibration while supporting the material guiding plate. This vibration can effectively destroy the bridging, adhesion and accumulation of materials on the surface of the material guiding plate, and is especially suitable for high viscosity or high solid content extraction systems. It greatly reduces the risk of dead corners and blockages in the discharge, and ensures the smoothness of discharge and the convenience of cleaning and maintenance of the equipment.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Please see Figures 1-4As shown, this utility model is a multi-stage extraction box with an inclined discharge bottom, including a box body 1. Two partitions 2 are fixedly installed on the inner wall of the box body 1, dividing the interior of the box body 1 into three chambers. Three discharge pipes 3 are fixedly installed on the front side of the box body 1, and the three discharge pipes 3 are respectively connected to the three chambers. Three sets of adjustable material guiding mechanisms 5 are installed inside the box body 1, which can adjust the angle of the bottom discharge plate. The three sets of adjustable material guiding mechanisms 5 are respectively installed inside the three chambers. Three sewage pipes 4 are fixedly installed on the lower surface of the box body 1, and the three sewage pipes 4 are respectively connected to the interior of the three chambers.

[0026] The adjustable material guiding mechanism 5 includes a mounting frame 501, which is fixedly mounted on the lower surface of the housing 1. A first motor 502 is fixedly mounted on the inner bottom of the mounting frame 501. A screw 503 is fixedly mounted on the output end of the first motor 502. A threaded tube 504 is threadedly connected to the outer surface of the screw 503. The threaded tube 504 is slidably connected to the inner wall of the housing 1 and extends into the interior of the chamber.

[0027] A mounting plate 505 is fixedly installed at one end of the threaded tube 504. Slide grooves 506 are provided on both sides of the mounting plate 505. Slider 507 is slidably connected inside the slide grooves 506. Springs 508 are fixedly installed on the inner wall of the slide grooves 506. One end of each spring 508 is fixedly connected to the outer surface of the slider 507.

[0028] A connecting plate 509 is fixedly installed on one side of the slider 507, and an abutment wheel 510 is rotatably connected to one end of the two connecting plates 509.

[0029] Each chamber is equipped with a guide plate 514. A rotating shaft 513 is fixedly installed on both sides of one end of the guide plate 514. The rotating shaft 513 and the partition plate 2 are rotatably connected to the inner wall of the box 1. The lower surface of the end of the guide plate 514 away from the rotating shaft 513 abuts against the outer surface of the abutting wheel 510.

[0030] Specifically, after the first motor 502 starts, it drives the screw 503 to rotate. Through the threaded transmission, the threaded tube 504 is vertically raised and lowered under the guidance of the inner wall of the box 1. The threaded tube 504 drives the mounting plate 505 and its components to move synchronously, thereby changing the support height of the abutment wheel 510. Since one end of the guide plate 514 is rotatably connected to the partition plate 2 and the inner wall of the box 1 through the rotating shaft 513, and the lower surface of its other end abuts against the abutment wheel 510, the change in the height of the abutment wheel 510 directly determines the tilt angle of the guide plate 514.

[0031] A second motor 511 is fixedly installed on one side of one of the connecting plates 509;

[0032] An eccentric wheel 512 is fixedly installed at the output end of the second motor 511;

[0033] Specifically, during the discharge process, the second motor 511 drives the eccentric wheel 512 to rotate. The unbalanced vibration generated by the rotation of the eccentric wheel 512 is transmitted to the connecting plate 509 through the housing of the second motor 511. Since the connecting plate 509 is slidably connected to the slide groove 506 through the slider 507, and a spring 508 is provided between the slider 507 and the inner wall of the slide groove 506, under the elastic force of the spring 508, the connecting plate 509 drives the abutment wheel 510 to generate continuous micro-vibration. This vibration helps to break the accumulation or adhesion of materials on the surface of the guide plate 514, so that the materials can slide more smoothly towards the discharge pipe 3, achieving efficient discharge.

[0034] Working Principle: During operation, the material to be extracted enters three chambers separated by partition 2 sequentially, completing the extraction reaction stage by stage. Each chamber is equipped with an independently operating adjustable guide mechanism 5 to control the discharge angle at the bottom of that chamber. Specifically, after the first motor 502 starts, it drives the screw 503 to rotate, causing the threaded tube 504 to rise and fall vertically under the guidance of the inner wall of the chamber 1 via threaded transmission. The threaded tube 504 drives the mounting plate 505 and its components to move synchronously, thereby changing the support height of the abutment wheel 510. Since one end of the guide plate 514 is rotatably connected to the partition 2 and the inner wall of the chamber 1 via a rotating shaft 513, and its other end abuts against the abutment wheel 510, the height change of the abutment wheel 510 directly determines the tilt angle of the guide plate 514 during the discharge process. The second motor 511 drives the eccentric wheel 512 to rotate. The unbalanced vibration generated by the rotation of the eccentric wheel 512 is transmitted to the connecting plate 509 through the housing of the second motor 511. Since the connecting plate 509 is slidably connected to the slide groove 506 through the slider 507, and a spring 508 is provided between the slider 507 and the inner wall of the slide groove 506, under the elastic force of the spring 508, the connecting plate 509 drives the abutment wheel 510 to generate continuous micro-vibration. This vibration helps to break the accumulation or adhesion of materials on the surface of the guide plate 514, so that the materials can slide more smoothly towards the discharge pipe 3. By controlling the first motor 502 in each of the three chambers respectively, the tilt angle of the guide plate 514 can be independently adjusted according to the material characteristics, reaction progress or discharge requirements in each chamber, so as to achieve differentiated and precise discharge control.
