Description

Technical Field

[0001] The utility model relates to the technical field of praseodymium-neodymium carbonate production, in particular to a fast separation filter press specially used for producing praseodymium-neodymium carbonate. Background Art

[0002] The filter press uses the pressure applied at the suspension inlet or the mechanical pressure applied to the wet material as the driving force for filtration. It is suitable for suspensions that require a large filtration pressure difference. It is also divided into intermittent operation and continuous operation. The intermittent operation tubular filter press and pressurized leaf filter are used for low-concentration suspension filtration.

[0003] An existing rapid separation filter press specifically for producing praseodymium and neodymium carbonate generally separates solid and liquid in the praseodymium and neodymium carbonate production process by centrifugal force or mutual squeezing between an extrusion plate and a filter box. During the separation process by squeezing the extrusion plate, solid impurities may clog the mesh due to mesh holes provided on the outer wall of the filter box, thereby preventing the liquid from being fully discharged and affecting the separation effect. After separation, the impurities need to be discharged from the inside of the filter box. Since no auxiliary discharge device is provided, it is inconvenient to quickly discharge the solid impurities, which makes it inconvenient to use. Therefore, it is necessary to propose a rapid separation filter press specifically for producing praseodymium and neodymium carbonate. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rapid separation filter press specially used for producing praseodymium and neodymium carbonate, comprising a filter box with a base and an outer wall provided with a plurality of evenly distributed mesh holes, the upper end face of the filter box being fixedly connected to a U-shaped bracket, the upper end face of the U-shaped bracket being passed through and rotatably connected to a rotating shaft, the outer wall of the rotating shaft being fixedly connected to a gear, the lower end of the rotating shaft being fixedly connected to a cross plate, the lower end of the cross plate being fixedly connected to a mounting frame, a first electric push rod being installed inside the mounting frame, the output end of the first electric push rod being passed through the mounting frame and fixedly connected to an extrusion plate, the outer wall of the extrusion plate being passed through with two symmetrically distributed notches, the lower end face of the cross plate being fixedly connected to two symmetrically distributed drive rods, the other ends of the two drive rods respectively passing through two notches and the outer walls being fixedly connected to brushes;

[0007] The upper end surface of the U-shaped bracket is provided with a driving mechanism.

[0008] In order to facilitate the rotation of the driven and meshing gears, as a preferred quick separation filter press for producing praseodymium and neodymium carbonate in the present invention, the driving mechanism includes a second electric push rod installed on the upper end face of the U-shaped bracket, and the output end of the second electric push rod is fixedly connected to a rack meshing with the gear.

[0009] In order to facilitate the discharge of the separated liquid, as a preferred quick separation filter press for producing praseodymium and neodymium carbonate of the present invention, the outer wall of the filter box is connected to a feed pipe, and the outer wall of the diversion bin is connected to a drain pipe.

[0010] In order to clear the mesh holes on the outer wall of the filter box, as a preferred embodiment of the rapid separation filter press specially used for producing praseodymium and neodymium carbonate of the present invention, the opposite sides of the two brushes are in contact with the inner wall of the filter box.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] When the utility model is in use, the first electric push rod cooperates with the extrusion plate, and the material can be separated into solid and liquid through the extrusion plate. During the solid-liquid separation process, the gear and the rotating shaft are driven by the driving mechanism to rotate, thereby driving the cross plate, the driving rod, the mounting frame, the first electric push rod, and the extrusion plate to rotate reciprocatingly. During the reciprocating rotation of the driving rod, the brush is driven to rotate reciprocatingly, thereby clearing the mesh holes on the outer wall of the filter box, facilitating the smooth discharge of liquid into the interior of the diversion bin.

[0015] When it is necessary to discharge the solid impurities separated inside the filter box, open the stop valve outside the discharge pipe, and then start the two vibration motors to vibrate the diversion bin, the filter box and the components connected thereto at the same time, so that the solid impurities can be discharged from the discharge pipe.

[0016] In summary, the mesh can be dredged to ensure the normal discharge of liquid, thereby improving the solid-liquid separation effect, and in the process of discharging solid impurities, the vibration motor is used to facilitate the rapid discharge of impurities, which is convenient for use.
