Description

Technical Field

[0001] The utility model relates to the technical field of filter residue recovery, in particular to a filter residue recovery and reuse device. Background Art

[0002] The filter residue is the solid particles in the filter slurry. For example, after sodium sulfate and barium hydroxide react and are filtered, the filter residue is solid barium sulfate. There is sodium chloride solute in the filtrate. Ferrous chloride is an easily soluble substance. Unless it is filtered after heating and crystallization, it will not be a filter residue. The filtration of the filter residue suspension can be carried out in different ways: when the pressure is constant, when the filtration flow rate is constant; when the pressure drop per unit thickness of the filter residue layer is constant; or when the pressure-time gradient is constant (that is, the pressure has a small and equal increment in the same time interval). In factory practice, there may be other filtration methods.

[0003] Please refer to the device for recovering and reusing sodium bromide from filter residues published by announcement No. CN219025364U. In this patent, it is proposed that "it includes a box body, a dissolving chamber is provided in the box body, the bottom space of the dissolving chamber is connected to the disintegration outlet, a vertical slot is provided at the upper end of the outlet, a filter screen is provided in the vertical slot, the filter screen is slidably connected to the inner wall of the vertical slot, a third rotating rod is provided in the vertical slot, the two ends of the third rotating rod are rotatably connected to the left and right inner walls of the vertical slot, a wire wheel is fixedly connected to the outer wall of the third rotating rod, a pulley is wound around the wire wheel, and the end of the pull rope away from the wire wheel is fixedly connected to the upper end of the filter screen.

However, the device does not have a corresponding separation and filtration structure during use, and cannot separate and recover the solid filter residue and liquid, and the separation efficiency is low. Therefore, this application proposes another technical solution to solve this problem. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 A filter residue recovery and reuse device in this embodiment includes a separation box 1, and a stirring and mixing mechanism is arranged on the top of the separation box 1.

[0023] In embodiment one, the stirring and mixing mechanism includes a supporting leg 2 fixedly mounted on the top of the separation box 1, a mixing box 3 is fixedly mounted on the top of the supporting leg 2, a feeding pipe 4 is fixedly mounted on the top of the mixing box 3, a feeding hopper 5 is fixedly mounted on the right side of the mixing box 3, a rotating motor 6 is fixedly mounted on the top of the mixing box 3, and a rotating rod 7 is fixedly mounted on the output shaft of the rotating motor 6.

[0024] Among them, a movable groove is provided on the top of the mixing box 3, and the rotating rod 7 is rotatably connected to the mixing box 3 through the movable groove, so that the rotating motor 6 can drive the rotating rod 7 to rotate. A stirring paddle 8 is provided on the outside of the rotating rod 7. The number of the stirring paddles 8 is several, and the stirring paddles 8 are evenly arranged on the outside of the rotating rod 7, which helps the stirring paddle 8 to mix the water and the mixture and accelerate the reaction. A discharge pipe 9 is fixedly installed at the bottom of the mixing box 3, and a through groove is provided on the top of the separation box 1. The discharge pipe 9 is located directly above the through groove, which helps to throw water and reactants into the interior of the mixing box 3. Slide seats 10 are fixedly installed on the inner walls of the left and right sides of the separation box 1. The slide seat 10 is slidably connected to the inside of the slide seat 10 with a slide rod 11. A slide groove is provided inside the slide seat 10. The slide rod 11 is slidably connected to the slide seat 10 through the slide groove, which facilitates the slide rod 11 to slide out.

[0025] In the second embodiment, a filtering and separating mechanism is arranged on the top of the two sliding rods 11, and the filtering and separating mechanism comprises a filtering frame 12 fixedly mounted on the top of the sliding rod 11, a first filtering plate 13 is fixedly mounted on the inner bottom wall of the filtering frame 12, a fixing frame 14 is fixedly mounted on the bottom of the filtering frame 12, and a second filtering plate 15 is fixedly mounted on the inner side of the fixing frame 14.

The filtering and separation mechanism includes a liquid outlet pipe 16 fixedly installed on the right side of the separation box 1, and a sealing door 17 is provided on the front of the separation box 1.

[0027] It should be noted that the filter residue recovery and reuse device, through the setting of the stirring and mixing mechanism, uses the functions of the rotating motor 6, the rotating rod 7 and the stirring paddle 8, so that the stirring paddle 8 can quickly mix the water and the reactants, so that the solid filter residue and the liquid are precipitated by the reaction, which helps to improve the efficiency of the mixing reaction. After the reaction, the discharge pipe 9 can be opened to send the liquid and the filter residue into the interior of the separation box 1 together. When passing through the first filter plate 13, the larger volume of filter residue is intercepted, and it is filtered again when passing through the second filter plate 15. Finally, the liquid continues to fall through the second filter plate 15 and flows on the inner bottom wall of the separation box 1. The liquid flows to the right and enters the liquid outlet pipe 16 for recovery.

[0028] The working principle of the above embodiment is:

[0030] In addition, solid filter residues with larger volumes are intercepted on the first filter plate 13, and other liquid mixtures continue to flow downward through the first filter plate 13 into the inner side of the fixed frame 14. The mixture is filtered again when passing through the second filter plate 15, and solid substances with smaller volumes are intercepted at the top of the second filter plate 15. The liquid continues to fall through the second filter plate 15 and flows on the inner bottom wall of the separation box 1. The liquid flows to the right into the liquid outlet pipe 16 for recovery. Finally, the sealing door 17 can be opened, and the first filter plate 13 and the second filter plate 15 can be slid out through the sliding rod 11 to recover the intercepted solid reactants, thereby greatly improving the flexibility and practicality of the device.
