DETAILED DESCRIPTION

[0015] The technical scheme in the embodiments of the utility model will be apparently and completely described below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative efforts belong to the range of protection of the utility model.

[0016] Please refer to Figures 1-4 The utility model provides a kind of arsenic gallium-containing oil sludge filter-pressing structure, including filter press main body 1, the side wall of filter press main body 1 is fixedly connected with liquid inlet pipe 2, the outer side end of liquid inlet pipe 2 is fixedly connected with stirring drum 3, the lower end of stirring drum 3 is fixedly equipped with motor 4, the motor shaft of motor 4 penetrates stirring drum 3 and is connected with rotating shaft 5, the outer wall of rotating shaft 5 is fixedly equipped with three stirring blades 6, the upper end of rotating shaft 5 is connected with perforated hollow cylinder 7 by connecting rod, the side wall upper end of stirring drum 3 is connected with material bottle 9 by solenoid valve 10.

[0017] The inlet pipe 2 facilitates the delivery of pretreated gallium arsenide-containing sludge to the filter press body 1. The stirring drum 3 pre-treats the gallium arsenide-containing sludge to be filtered. The motor 4, in conjunction with the rotating shaft 5, easily drives the stirring blades 6 to rotate. Simultaneously, the material bottle 9 contains flocculant, which, with the help of the solenoid valve 10, controls the addition of flocculant to the stirring drum 3. The stirring blades 6 aggregate the fine particles in the gallium arsenide-containing sludge into larger particles, reducing clogging of the filter cloth pores and preventing the formation of a dense filter cake that hinders further filtrate passage, thus ensuring filtration speed. Furthermore, the filter press requires less frequent maintenance. The perforated hollow cylinder 7 allows for uniform addition of flocculant, ensuring a complete reaction. It is convenient to use and highly practical.

[0018] It also includes an extrusion structure 8, which is screwed to the inner wall of the material bottle 9;

[0019] The extrusion structure 8 includes a cover plate 81, which is screwed to the inner wall of the material bottle 9. A hydraulic cylinder 82 is fixedly mounted on the upper end of the cover plate 81. The piston rod of the hydraulic cylinder 82 passes through the cover plate 81 and extends into the interior of the material bottle 9. A pressure plate 83 is fixedly mounted on the end of the piston rod of the hydraulic cylinder 82. The outer wall of the pressure plate 83 is tightly fitted to the inner wall of the material bottle 9.

[0020] When the pressure in the mixing drum 3 is too high, the self-feeding ability of the material bottle 9 becomes poor. The cover plate 81 is screwed into the material bottle 9, and the pressure plate 83 is inserted into the material bottle 9. The hydraulic cylinder 82 is activated to control the piston rod to move downward and drive the pressure plate 83 to squeeze the flocculant in the material bottle 9 and send it into the mixing drum 3.

[0021] A support cylinder 11 is inserted into the inner wall of the stirring drum 3, and the liquid inlet pipe 2 passes through the support cylinder 11.

[0022] The support cylinder 11 can collect gallium arsenide-containing sludge to the bottom of the mixing drum 3, making it convenient for the mixing blades 6 to stir it.

[0023] A support plate 12 is fixedly mounted on the inner wall of the mixing drum 3. The support plate 12 is sleeved on the outer wall of the rotating shaft 5, and the support plate 12 is rotatably connected to the rotating shaft 5.

[0024] Support plate 12 ensures the stability of the rotation of shaft 5.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
