Description

Technical Field

[0001] The utility model belongs to the technical field of fine chemical production, and specifically relates to a device for quickly filtering reaction inorganic salts. Background Technique

[0002] During fine chemical reactions, inorganic salts are inevitably generated during the reaction process or quenching process. For example, when quenching Grignard reagents with acid, magnesium chloride or magnesium bromide is generated; when using raw materials with hydrochloride salts and adding alkali for liberation, the corresponding sodium chloride or potassium chloride is generated; in the exchange reaction involving butyllithium, lithium bromide salt is generated in the reaction system; during coupling reactions, inorganic bases need to be added for catalytic reactions, and potassium bromide or sodium chloride and other inorganic salts are generated after the reaction; during bromine-chlorine exchange reactions, the corresponding reactions are promoted to continue according to the different solubilities of the salts.

[0003] In the above reaction systems, sometimes the inorganic salts are in the reaction system and need to be filtered before quenching, and sometimes the inorganic salts are present in the aqueous solution after quenching. After the reaction is completed, the aqueous solution is concentrated by distillation to form a supersaturated solution of the inorganic salt, and then filtered.

[0004] However, for the existing filtering devices currently, when filtering solid-liquid mixtures to extract inorganic salts from the solid-liquid mixtures, the filtering efficiency needs to be further improved. In view of this, the present utility model is specifically proposed. Summary of the Utility Model

[0005] The technical problem to be solved by the present utility model is to overcome the deficiencies of the prior art and provide a device for quickly filtering reaction inorganic salts that can overcome the above problems or at least partially solve the above problems.

[0007] A device for quickly filtering reaction inorganic salts includes a tank body and a tank cover detachably connected to the tank body; a filter plate disposed inside the tank body; a piston disk slidably connected inside the tank body. Among them, a pressurization chamber is provided above the piston disk inside the tank body; an elastic reset member is disposed on the tank cover and is used for resetting the piston disk; a booster pump is fixedly installed on the tank body, and a first pipeline, one end of which is fixedly communicated with the input end of the booster pump and the other end is disposed on the tank cover and communicated with the pressurization chamber.

[0008] Preferably, the tank cover is detachably connected to the tank body through a plurality of fixing bolts.

[0009] In order to increase the sealing performance at the connection between the can lid and the can body, preferably, a connection ring is fixedly connected to the can lid, a sealing ring is arranged on the connection ring, and the sealing ring is in close fit with the inner wall of the pressurization chamber.

[0010] Preferably, a support ring is fixedly connected inside the can body, a limit guide rod is fixedly connected to the can lid, and the filter plate abuts against the support ring through the limit guide rod.

[0011] Preferably, the elastic reset member includes a tension spring, the tension spring is sleeved on the limit guide rod, one end of the tension spring is fixedly connected to the can lid, and the other end is fixedly connected to the piston disc.

[0012] In order to be able to limit and guide the piston disc, further, the piston disc is slidably connected to the limit guide rod.

[0013] In order to facilitate the discharge of the liquid separated by filtration from the can body, preferably, a discharge pipe is fixedly communicated with the bottom of the can body.

[0014] In order to be used for back-cleaning the filter plate, further, a second pipe is fixedly communicated below the filter plate of the can body, one end of the second pipe far away from the can body is fixedly communicated with the pressurization chamber, and valve switches are arranged on both the second pipe and the discharge pipe.

[0015] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0016] In the utility model, when filtering the solid-liquid mixture and then extracting the inorganic salt in the solid-liquid mixture, the gas filled into the pressurization chamber pushes the piston disc to move downward, thereby pressing the solid-liquid mixture in the can body, thus improving the filtration efficiency. And during the filtration process, when the filter plate is blocked, it is not necessary to disassemble the filter plate, and the filter holes of the filter plate can be back-cleaned, so as to achieve the purpose of unclogging the filter holes of the filter plate.

[0022] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments with reference to the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0023] Embodiment 1:

[0024] Refer to Figure 1 , Figure 2 , Figure 3 , a rapid filtration reaction inorganic salt device, including a tank body 1 and a tank cover 101 detachably connected to the tank body 1; a filter plate 3 disposed inside the tank body 1; a piston disc 4 slidably connected inside the tank body 1. Among them, a pressurization chamber is provided above the piston disc 4 inside the tank body 1; an elastic reset member is provided on the tank cover 101 and is used for resetting the piston disc 4; a booster pump 402 is fixedly installed on the tank body 1, and one end of a pipe 1 403 is fixedly communicated with the input end of the booster pump 402, and the other end is disposed on the tank cover 101 and is communicated with the pressurization chamber.

[0025] The tank cover 101 is detachably connected to the tank body 1 through a plurality of fixed bolts 102.

[0026] A support ring 301 is fixedly connected inside the tank body 1, a limit guide rod 302 is fixedly connected to the tank cover 101, and the filter plate 3 abuts against the support ring 301 through the limit guide rod 302.

[0027] The elastic reset member includes a pull spring 401. The pull spring 401 is sleeved on the limit guide rod 302. One end of the pull spring 401 is fixedly connected to the tank cover 101, and the other end is fixedly connected to the piston disc 4.

[0028] The piston disc 4 is slidably connected to the limit guide rod 302.

[0029] The bottom of the tank body 1 is fixedly communicated with a discharge pipe 303.

[0030] During use, first pour the well - mixed solid - liquid mixture into the tank body 1. At this time, the liquid in the solid - liquid mixture flows out through the filter holes of the filter plate 3, then flows to the bottom inside the tank body 1 and is discharged from the tank body 1 through the discharge pipe 303. While the solid inorganic salts in the solid - liquid mixture are blocked on the filter plate 3. Subsequently, cover the tank cover 101 onto the tank body 1, thus closing the tank body 1, and then screw on the fixing bolt 102 used to limit and fix the tank cover 101 to improve the stability of the tank cover 101 covered on the tank body 1. Then start the booster pump 402, so that the booster pump 402 sucks external gas and fills it into the booster chamber through the first pipeline 403. At the same time, the gas filled into the booster chamber pushes the piston disk 4 to move downward and stretches the tension spring 401, thereby pressing the solid - liquid mixture in the tank body 1, making the liquid in the solid - liquid mixture flow out quickly through the filter holes of the filter plate 3, thus improving the filtration efficiency;

[0031] When the filtration is completed and it is necessary to take out the inorganic salts blocked on the surface of the filter plate 3 in the tank body 1, first unscrew the fixing bolt 102 used to limit and fix the tank cover 101, then remove the tank cover 101 covered on the tank body 1, and then open the tank body 1, so as to facilitate taking out the inorganic salts blocked on the surface of the filter plate 3 from the tank body 1.

[0032] It should be noted that the first pipeline 403 is a stretchable and shrinkable hose, so the first pipeline 403 will not interfere with the disassembly and installation of the tank cover 101.

[0033] Embodiment 2:

[0034] Refer to Figure 2 、 Figure 3 A rapid - filtration reaction inorganic salt device is basically the same as that in Embodiment 1. Further, a second pipeline 404 is fixedly connected below the filter plate 3 of the tank body 1, and one end of the second pipeline 404 far from the tank body 1 is fixedly connected to the booster chamber. Valve switches are arranged on both the second pipeline 404 and the discharge pipe 303;

[0035] During the filtration process, when the filter plate 3 is blocked and affects the filtration of the solid - liquid mixture, first close the valve switch of the discharge pipe 303, and then open the valve switch of the second pipeline 404. At this time, the gas in the booster chamber is filled into the cavity at the lower end of the tank body 1 through the second pipeline 404, thereby performing a reverse cleaning on the filter holes of the filter plate 3, so as to achieve the purpose of unclogging the filter holes of the filter plate 3. A one - way valve is arranged on the second pipeline 404;

[0036] Meanwhile, when the gas in the pressurizing chamber is filled into the lower end part of the tank body 1 through the second pipeline 404, the stretched spring 401 automatically resets under its own elastic potential energy. At the same time, when the spring 401 recombines, it can pull the piston disk 4 to reset upward synchronously, thus stopping the pressure on the solid-liquid mixture and avoiding the continuous pressure of the piston disk 4 on the solid-liquid mixture, which affects the reverse cleaning of the filter holes of the filter plate 3 by the gas filled into the lower end part of the tank body 1;

[0037] When the filter holes of the filter plate 3 are cleared, close the valve switch of the second pipeline 404, and then open the valve switch of the discharge pipe 303, and the filtration of the solid-liquid mixture can be continued, thus further improving the filtration efficiency.

[0038] Embodiment 3:

[0039] Refer to Figure 2 、 Figure 4 A rapid filtration reaction inorganic salt device is basically the same as that in Embodiment 1. Further, a connecting ring 2 is fixedly connected to the tank cover 101, and a sealing ring 201 is arranged on the connecting ring 2. The sealing ring 201 is in contact with the inner wall of the pressurizing chamber; when the tank cover 101 is in contact with the top of the tank body 1, the connecting ring 2 inserted into the tank body 1 presses the sealing ring 201 to be in contact with the inner wall of the tank body 1, thereby increasing the sealing performance of the tank body 1 and avoiding the leakage of the gas in the pressurizing chamber into the pressurizing chamber, which affects the downward movement of the gas pushing the piston disk 4.

[0040] The above is only a preferred embodiment of the present invention and does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention.
