Description

Rotary grating device for extraction box

Technical Field

The invention belongs to the technical field of wet metallurgy mechanical equipment, and particularly relates to a rotary grating device for an extraction box.

Background

In the extraction process, the clarifying tank is used for separating the oil phase from the liquid phase according to the principles of oil phase floating and liquid phase sinking, so that the clarifying process is a process of layering the oil phase and the liquid phase, and the process is generally multistage. Two to three grids are generally arranged in the clarifying tank, and the grids have the following functions: the solution entering the clarifying tank is subjected to steady flow, so that the solution flows through orderly without turbulence; the solution tension is eliminated, and the oil phase and the liquid phase are more favorably layered; the flow speed of the solution is slowed down, and the clarification time of the solution is prolonged. The grid installation back position that uses at present also is fixed simultaneously, and unable removal or rotation, the grid will be cut apart into three-section or four sections with the clarification tank, and every section will set up a manhole, when the clarification tank is maintained the clearance, the workman's operation of being convenient for, and the increase of manhole not only makes the processing cost and the increase of dimension guarantor cost, has also increased volatilizing of organic phase simultaneously to manufacturing cost has further been increased.

Disclosure of Invention

The invention aims to solve the technical problem of providing a rotary grating device for an extraction box, which is convenient to operate, simple in structure and practical and aims to solve a series of cost problems caused by the fact that the grating of the existing clarification box cannot move or rotate.

The technical scheme is as follows for solving the technical problem of the invention:

a rotary grating device for an extraction box is characterized by comprising a box body, a plurality of partition plates (7) and a grating (2); the box body is divided into a plurality of clarification tanks (1) by a plurality of clapboards (7); two grids (2) are arranged in each stage of clarification tank (1), the lower ends of the grids (2) are matched with a rotating pin (6), the rotating pin (6) is arranged on a partition plate (7), and the grids (2) can rotate through the rotating pin (6); grid (2) upper end installation bayonet lock (4), fixed mounting have on baffle (7) with bayonet lock (4) complex cassette (3), bayonet lock (4) and cassette (3) are located one side of grid (2), the opposite side of grid (2) is equipped with dog (5), dog (5) and baffle (7) fixed connection.

The device is characterized in that the number of the rotating pins (6) is two, the number of the clamping pins (4) is two, and the number of the clamping seats (3) is two; the two rotating pins (6) are respectively arranged at two ends of the bottom of the grating (2), and the two groups of clamping pins (4) and the clamping seats (3) are respectively arranged at two ends of the top of the grating (2).

The invention has the beneficial technical effects that: compared with the prior art, the rotary grating for the extraction box is suitable for an extraction clarification process, improves the structure of the existing clarification box, solves the problem of inconvenient maintenance and cleaning of the clarification box, reduces the number of manholes, reduces the loss of organic phases, is convenient to install and simple to operate, and reduces the production cost.

Detailed Description

The invention will be further described with reference to the accompanying drawings.

As shown in fig. 1-5, the rotary grating device for the extraction box of the invention comprises a box body, a plurality of partition plates 7 and a grating 2; the box body is provided with a material inlet and a material outlet, and the box body is divided into a multi-stage clarification tank 1 by a plurality of partition plates 7; two grids 2 are arranged in each stage of clarification tank 1, the lower ends of the grids 2 are matched with a rotating pin 6, the rotating pin 6 is arranged on a partition plate 7, and the grids 2 can rotate through the rotating pin 6; bayonet 4 is installed to 2 upper ends of grid, on the baffle 7 fixed mounting have with 4 complex cassette 3 of bayonet lock, bayonet lock 4 and cassette 3 are located one side of grid 2, the opposite side of grid 2 is equipped with dog 5, dog 5 and 7 fixed connection of baffle, dog 5 can only rotate to the direction of cassette 3 when making 2 rotations of grid. Preferably, the number of the rotating pins 6 is two, the number of the clamping pins 4 is two, and the number of the clamping seats 3 is two; two rotating pins 6 are respectively arranged at two ends of the bottom of the grid 2, and two groups of clamping pins 4 and clamping seats 3 are respectively arranged at two ends of the top of the grid 2.

When clearing up is maintained to clarification tank 1, take out bayonet lock 4, fall grid 2 through rotatory 6 towards 3 directions rotations of cassette, after the operation is accomplished, grid 2 resets, puts back bayonet lock 4 and is spacing with grid 2.
