Detailed Description

In order to make the content of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

As shown in figure 1, a filter with good sealing performance for tetramethylammonium hydroxide production comprises a base 1 and a tank body 8.

Wherein a first supporting plate 2 is arranged on one side above a base 1, a second supporting plate 3 is arranged on one side of the upper portion of the base 1, which is symmetrical to the first supporting plate 2, bearing holes 6 are formed in the upper ends of the first supporting plate 2 and the second supporting plate 3, a bearing 7 is arranged in each bearing hole 6, a fixing plate 4 is arranged on one side of the first supporting plate 2, a motor 5 is arranged above each fixing plate 4, transmission shafts 17 are symmetrically arranged at the centers of the surfaces of the two sides of a tank body 8, the transmission shafts 17 are arranged in inner rings of the bearings 7, a filter screen cap 9 is arranged above the inner portion of the tank body 8, a blanking hopper 14 is arranged below each filter screen cap 9, a baffle 16 is arranged at the bottom outlet of the blanking hopper 14, a hinge 15 is arranged on one side wall of the bottom outlet of the blanking hopper, and the baffle 16 is connected with the outer wall of the bottom outlet of the blanking hopper 14 through the hinge 15, the top of the jar body 8 is equipped with inlet pipe 10, be equipped with solenoid valve 11 on the inlet pipe 10, the bottom of the jar body 8 is equipped with discharging pipe 12, be equipped with two 13 of solenoid valves on the discharging pipe 12.
