Description

A trommel screen equipment for rapid screening of slurry

technical field

The utility model relates to a device in the metallurgical and chemical industry, in particular to a device for quickly screening slurry.

Background technique

In the traditional process of solid separation of different particle sizes, dry sieving or water sieving is mostly used, but the sieving rate is low, and the sieving rate is also low, and due to the influence of the strength of the sieve, the requirements for the pore size of the sieve are relatively strict. Sieving of smaller particle sizes becomes difficult.

Contents of the invention

The technical problem to be solved by the utility model is to overcome the defects of the above-mentioned technologies and provide a solid separation device capable of effectively separating different particle sizes.

For this reason, the technical scheme adopted by the utility model is as follows: a trommel screen equipment for rapid screening of slurry, including a support (1), a liquid receiving tank (2) on the support, a feed port (3) in the front section of the drum, The drum (4) on the liquid receiving tank, the drum (4) includes the main shaft (10), the screen (5) installed in the liquid receiving tank, the external spray washing device (6) and the discharge port (7, 8), the bracket is provided with an adjustable hanger (9), the angle of the drum can be adjusted after the main shaft (10) is suspended, and an ultrasonic device (11) is provided at the bottom of the liquid receiving tank.

Further, the hanger (9) is an adjustable hanger to adjust the angle of the drum and adjust the under-screen effect and screening efficiency.

Further, the drum (4) is connected with a frequency converter to adjust the rotating speed of the drum, and also realize the adjustment of the under-screening effect and screening efficiency.

Further, the outlets (7, 8) are provided with buffer interfaces to realize the buffering of the slurry after entering the equipment and protect the screen.

Further, the outlets (7, 8) are divided into oversize outlets and undersize outlets.

Further, the liquid receiving tank (2) adopts a semi-closed form.

Further, the mechanism of the drum (4) can realize quick replacement of the screen (5).

Further, the screen (5) can choose screens with different apertures, up to 800 meshes, and the screen has a special lining design to protect the main screen from damage.

Further, the jet washing device (6) can efficiently clean the screen (5) without disassembling the screen.

When in use, the trommel screen adopts a two-stage or multi-stage series connection method, and screens with different apertures are selected according to requirements to ensure product quality and screening efficiency. When the mixed slurry containing A and B enters the processing equipment, the B slurry is screened to more than 80% after passing through the first-stage drum screen, and then screened to 95% of the B slurry after passing through the second-stage drum screen to achieve pulp The separation efficiency of materials A and B can reach more than 95%. By analogy, when the process requires, the separation efficiency can be improved by increasing the number of stages, and finally meet the product separation requirements.

The utility model solves the problem of separation of smaller particle size slurry in the industry, can continuously feed and process, has high efficiency, and solves the problem of solid-solid separation in the industry at the same time.

Detailed ways

The copper-cobalt alloy leaching equipment shown in Figure 1-2 is composed of a support (1), a liquid receiving tank (2) mounted on the support and rollers (4, 5). The liquid receiving tanks (2) are respectively provided with discharge ports (7, 8), and an ultrasonic device (11) is installed on the inner side of the bottom, and a spray washing device (6) is arranged on one side of the drum. The transmission system consists of a motor and a reducer. The transmission system is connected with the frequency converter to adjust the rotating speed of the drum.

The working process of the utility model is as follows: when lime is used to precipitate cobalt and nickel, the precipitated slurry is pumped into the drum, and the slurry is affected by gravity, and two kinds of materials with different particle sizes are screened through the selection of the screen. After sieving, it can be divided into two kinds of materials: upper sieve and lower sieve. The upper sieve material can be subjected to the next process or discarded or subjected to secondary screening according to requirements. , the specific series and parallel processes and series are selected and judged by the operating conditions. After a certain period of use, when the screening efficiency decreases, check the screen and perform spray washing or pickling, and turn on the ultrasonic device to speed up the washing rate.
