Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of flotation machine, especially relates to a flotation machine discharge scraping floating device. BACKGROUND

[0002] Flotation machine is the abbreviation of floatation concentrator, and refers to the mechanical equipment for completing the flotation process. In the flotation machine, the ore pulp treated by adding reagent is stirred and aerated, so that some ore particles are selectively fixed on the gas bubbles. The gas bubbles float to the surface of the ore pulp and are scraped to form a froth product. The remaining part is retained in the ore pulp to achieve the purpose of separating minerals. There are many structural forms of flotation machines, and the most commonly used is the mechanical stirring type flotation machine.

[0003] At present, when the flotation machine for ore dressing discharges and scrapes, the machine box is driven by a motor-driven shaft rod structure with a scraper to scrape the froth in the machine box. However, the discharge tank wall structure of such machine box is relatively simple, the froth has low discharge efficiency at the machine box, and the simple plate structure of the scraper has poor scraping effect on the froth, thereby reducing the discharge efficiency of the flotation machine. Therefore, we propose a flotation machine discharge scraping floating device. SUMMARY

[0004] The main purpose of the utility model is to provide a flotation machine discharge scraping floating device. The outer low inclined plate and the inner inclined guide plate are arranged at the inclined discharge tank wall of the flotation machine, and the vertical plate extending into the flotation machine is arranged below the inner inclined guide plate. At the same time, the vertical plate is fixed with an inclined guide plate outside. The guide inclined plate body at the inclined discharge tank wall can assist the smooth outward discharge of the floating material in the flotation machine, thereby improving the discharge efficiency of the flotation machine. The scraping mechanism is arranged at the scraping shaft of the flotation machine. The improved scraper can be installed at the scraping shaft of the flotation machine. The scraper with V-shaped plate groove cooperates with the expanded semicircular strip seat to scrape the floating material outward. Then the scraped floating material is pushed close to the inclined discharge tank wall. Then the floating material floats towards the inner inclined guide plate along the inclined guide plate of the vertical plate. The floating material can also flow to the outer low inclined plate along the inclined discharge tank wall to accelerate the outward discharge. The flotation machine can discharge more effectively, and the problems in the background art can be effectively solved.

[0005] To achieve the above purpose, the utility model adopts the technical scheme:

[0006] A flotation machine discharge scraping device includes a flotation machine and a scraping shaft. The scraping shaft is mounted on one side of the flotation machine's casing via a shaft seat. An inclined box wall is provided on the outer wall of the flotation machine away from the scraping shaft. The device also includes an outer low-inclination plate, an inner inclined guide plate, a vertical connecting plate, and a scraping mechanism. The scraping mechanism includes an arc-shaped plate, a back connecting plate, a scraper, a counter-mounted plate, and a semi-circular strip seat. The outer low-inclination plate gradually slopes outward from the side of the inclined box wall away from the scraping shaft. An inner inclined guide plate is fixed into the flotation machine on the side of the inclined box wall away from the outer low-inclination plate. A vertical connecting plate is fixed to the lower plate surface, and an inclined guide plate is provided on the vertical connecting plate protruding towards the plate surface inside the flotation machine. An arc-shaped mounting plate is symmetrically locked to the outer wall of the scraper shaft by bolts, and a back connecting plate is fixed between the outer arc plate surface of the arc-shaped mounting plate and the scraper. A V-shaped plate groove is provided on the plate surface of the scraper away from the back connecting plate, and a plate rib is provided on the groove surface of the V-shaped plate groove. A pair of mounting plates are symmetrically installed on the other plate surface of the scraper away from the V-shaped plate groove by bolts, and the pair of mounting plates are symmetrically welded to the outer wall of the semi-circular bar seat. The side seat opening of the semi-circular bar seat faces the groove opening of the V-shaped plate groove.

[0007] Furthermore, the surface of the semi-circular bar seat is provided with a V-shaped side seat opening, and the V-shaped side seat opening of the semi-circular bar seat abuts against the scraper near the V-shaped plate groove.

[0008] By adopting the above technical solution, the semi-circular strip seat has one side of the seat body with a V-shaped side seat opening against the scraper near the V-shaped plate groove, which facilitates the connection between the V-shaped plate groove and the semi-circular strip seat.

[0009] Furthermore, the ribs have two sets of protrusions arranged on the inner wall of the V-shaped groove;

[0010] By adopting the above technical solution, double sets of ribs are set in the V-shaped plate groove for protrusion reinforcement.

[0011] Furthermore, a mounting hole is provided between the surface of the mounting plate and the scraper, and a bolt is screwed between the mounting holes of the mounting plate and the scraper.

[0012] By adopting the above technical solution, bolts are screwed between the mounting holes of the mounting plate and the scraper, which facilitates locking the mounting plate at the scraper to provide support for the semi-circular strip seat.

[0013] Furthermore, on the side of the scraper away from the semi-circular bar seat, three sets of back connecting plates are arranged and welded on the outer side, and an arc-shaped plate is welded on the outer side of the three sets of back connecting plates.

[0014] By adopting the above technical solution, after the scraper is welded with three sets of back connecting plates and three sets of arc mounting plates, the arc mounting plates can be bolted to the scraper shaft for installation.

[0015] Furthermore, two sets of bolts are screwed between the arc plate and the shaft of the scraper shaft, and the inner arc surface of the arc plate abuts against the outer arc surface of the shaft of the scraper shaft;

[0016] By adopting the above technical solution, after the arc-shaped plate is clamped against the outside of the scraper shaft, the arc-shaped plate is firmly locked to the outside of the scraper shaft with two sets of bolts for installation.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention provides an outer low inclined plate and an inner inclined guide plate on the inclined box wall of the flotation machine, and a vertical connecting plate extending into the flotation machine is provided below the inner inclined guide plate. At the same time, an inclined guide plate is fixed outside the vertical connecting plate. The guiding inclined plate on the inclined box wall can assist the flotation material in the flotation machine to be smoothly guided outward, thereby improving the flotation material discharge efficiency of the flotation machine.

[0019] Furthermore, a scraping mechanism is installed at the scraper shaft of the flotation machine. The scraping mechanism, with its improved scraper, can be installed at the scraper shaft of the flotation machine. The scraper with V-shaped grooves, together with the semi-circular bar seat that expands the volume, can scrape more floating material out of the machine. The scraped floating material is then pushed closer to the inclined box wall, and then floats along the inclined guide plate of the vertical connecting plate towards the inner inclined guide plate. The floating material can also flow along the inclined box wall towards the outer low inclined plate to accelerate its outward discharge, effectively ensuring that the flotation machine can discharge more material.
