Description

Technical Field

[0001] The utility model relates to the field of slag box type filter presses, in particular to a slag box type filter press for sulfur slag treatment. Background Art

[0002] Sulfur slag refers to waste generated during the extraction of sulfur or sulfur-containing compounds. This waste may contain incompletely purified sulfur, other minerals, and various substances remaining from the chemical treatment process. During the processing of sulfur slag, a filter press is required for solid-liquid separation. It effectively separates solids and liquids by applying pressure. The use of appropriate filter press technology can help sulfur slag remove excess water or solvents, thereby reducing its volume and facilitating subsequent processing or recycling.

[0003] After using the slag box filter press, sulfur residue may remain on the filter plate. The residual sulfur residue not only easily occupies the pores of the filter cloth or changes the surface characteristics of the filter plate, resulting in poor fluid permeability in the subsequent filtration process, thereby reducing the filtration efficiency of the sulfur residue, but also the long-term accumulation of sulfur residue may cause physical damage to the filter plate. The existing method is generally to manually clean these sulfur residues. The manual cleaning method not only increases the workload of the workers, but also has low cleaning efficiency, reducing the practicality of the slag box filter press. Summary of the Invention

[0004] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides a slag box filter press for sulfur slag treatment to solve the above-mentioned technical problems.

[0006] A second electric guide rail is slidably mounted on the first electric guide rail, a slider is slidably mounted on the second electric guide rail, a lifting cylinder is mounted at the bottom of the slider, an infrared sensor connected to the bottom end surface of the slider is provided on each of the left and right sides of the lifting cylinder, and a lifting frame located above the filter plate is detachably mounted on the bottom piston of the lifting cylinder;

[0007] The conveying pipe is connected with the air outlet end of the high-pressure air pump through a connecting hose, and a row of nozzles is arranged at the bottom of the conveying pipe.

[0008] Two motors are arranged on the lifting frame and correspond to the two rollers respectively, and the output shaft of the motor is coaxially connected with the roller after penetrating through the side surface of the lifting frame.

[0009] Preferably, the infrared sensor is arranged in a staggered manner with the brush and the nozzle, and the infrared sensor is located outside the brush and the nozzle.

[0010] Preferably, the left and right rows of nozzles at the bottom of the conveying pipe are respectively arranged in a left downward inclined manner and a right downward inclined manner, and each row of nozzles is composed of a plurality of equidistantly distributed nozzles.

[0011] Preferably, the brush extends outside the lifting frame, and the left and right groups of brushes are located above the left and right rows of nozzles respectively.

[0012] Preferably, the brush is made of nylon material.

[0013] The beneficial effects of the present application are as follows:

[0014] The brush and the nozzle are arranged, the brush is driven to rotate by the roller to brush off the residual sulfur residue on the filter plate, or to loosen part of the relatively firm sulfur residue adhered, and the high-pressure gas sprayed by the nozzle blows off other residual sulfur residue, thereby reducing the residual sulfur residue on the filter plate, improving the filtering efficiency of the sulfur residue, and making the cleaning process faster and more automatic, reducing the workload of manual operation, improving the work efficiency, and improving the practicability of the residue tank type filter press.
