Description

Technical Field

[0001] This utility model relates to the technical field of potassium chloride solution purification devices, specifically, to a potassium chloride solution purification device. Background Technology

[0002] In the chemical production field, potassium chloride solution is an important raw material or intermediate product, and its purity has a crucial impact on subsequent production processes and product quality. Many processes that require potassium chloride solution, such as the deep processing of potassium salts and the preparation of certain fine chemical products, place extremely high demands on the purity of the potassium chloride solution.

[0003] Currently, existing potassium chloride solution purification devices have some obvious shortcomings in practical applications. On the one hand, most purification devices use a simple single-stage filtration structure, which can only remove larger particulate impurities. It is difficult to effectively remove some tiny suspended solids, colloids, and ionic impurities, resulting in the purity of the purified potassium chloride solution failing to meet the requirements of high-end production processes.

[0004] On the other hand, after prolonged use, many existing potassium chloride solution purification devices inevitably accumulate a large amount of impurities on their inner walls.

[0030] like Figures 1-5 As shown, it illustrates a potassium chloride solution purification device according to an embodiment of the present invention, including: a purification chamber 1, an outlet pipe 101 fixedly installed at the bottom of the purification chamber 1, a purification mechanism installed inside the purification chamber 1, a cleaning mechanism installed on the left outer wall of the purification chamber 1, and a limiting mechanism installed on the rear outer wall of the purification chamber 1.

[0031] Pretreatment chamber 2 is located directly above the top of purification chamber 1. Several sets of support rods 4 are fixedly installed at the bottom edge of pretreatment chamber 2. The bottom end of each set of support rods 4 is fixedly connected to purification chamber 1. A connecting pipe 3 is sealed and connected at the middle of the bottom of pretreatment chamber 2. The other end of the connecting pipe 3 is sealed and connected to purification chamber 1. An inlet pipe 5 is fixedly installed at the top of pretreatment chamber 2. A stirring mechanism is installed inside pretreatment chamber 2.

[0032] For example, such as Figure 4As shown, the purification mechanism includes an installation slot 6, an installation frame 7, a handle 8, an installation channel 9, a coarse filter screen 10, an activated carbon adsorption plate 11, and a polyvinylidene fluoride microfiltration membrane plate 12. An installation slot 6 is provided on the outer right side of the purification chamber 1. An installation frame 7 is slidably installed inside the installation slot 6. A handle 8 is fixedly installed on the outer right side of the installation frame 7. An installation channel 9 is provided inside the installation frame 7. A coarse filter screen 10 is fixedly installed at the top of the installation channel 9. An activated carbon adsorption plate 11 is fixedly installed below the coarse filter screen 10 inside the installation channel 9. A polyvinylidene fluoride microfiltration membrane plate 12 is fixedly installed below the activated carbon adsorption plate 11 inside the installation channel 9.

[0033] For example, such as Figure 3 As shown, the limiting mechanism includes a limiting rod 13, a limiting hole 1301, a fixing plate 14, a spring 15, and a pull ring 16. The limiting rod 13 is longitudinally and slidably installed on the outer wall of the rear end of the purification chamber 1. The fixing plate 14 is fixedly installed on the outer wall of the rear end of the limiting rod 13. The spring 15 is sleeved on the limiting rod 13. The front end of the spring 15 is fixedly connected to the outer wall of the rear end of the purification chamber 1, and the rear end of the spring 15 is fixedly connected to the fixing plate 14. The pull ring 16 is fixedly installed on the outer wall of the rear end of the fixing plate 14. The mounting bracket 7 has a limiting hole 1301 that matches the limiting rod 13 at the corresponding position.

[0034] For example, such as Figure 4 As shown, the stirring mechanism includes a motor 17, a rotating shaft 18, stirring rods 19, and a feed hopper 20. The motor 17 is fixedly installed at the middle position of the top of the pretreatment chamber 2. The rotating shaft 18 is fixedly installed at the output end of the motor 17. Several sets of stirring rods 19 are fixedly installed on the rotating shaft 18. The feed hopper 20 is fixedly installed at the top of the pretreatment chamber 2. Sealing gaskets are fixedly installed at the connection between the mounting frame 7 and the outer surface of the mounting groove 6. A first solenoid valve 31 is fixedly installed on the connecting pipe 3, and a second solenoid valve 32 is fixedly installed on the liquid outlet pipe 101. A control panel 33 is fixedly installed on the outer wall of the front end of the purification chamber 1. Rubber gaskets 34 are fixedly installed at the four corners of the bottom of the purification chamber 1.

[0035] In some examples, for ease of control, the motor 17, water pump 29, first solenoid valve 31, and second solenoid valve 32 are all electrically connected to the control panel 33. First, the operator can add potassium chloride solution into the pretreatment chamber through the inlet pipe 5, and simultaneously add the purifying agent into the pretreatment chamber 2 through the feed hopper 20. Then, the motor 17 can be started via the control panel 33, driving the stirring rod 19 to mix the potassium chloride solution and purifying agent, thereby improving the efficiency and effect of the impurity removal reaction. Then, when the first solenoid valve 31 is opened, allowing the potassium chloride solution to enter the purification chamber 1 through the connecting pipe 3 and pass through the mounting bracket 7, the coarse filter 10 and activated carbon adsorption plate... The 11 and 12 polyvinylidene fluoride microfiltration membranes can effectively intercept larger particulate impurities, organic impurities, some pigments, as well as tiny suspended solids and microorganisms, resulting in a higher purity and better quality of the purified potassium chloride solution. In addition, after the operator slides the mounting frame 7 into the mounting groove 6, the limiting rod 13 is engaged with the limiting hole 1301 on the mounting frame 7 under the action of the spring 15, thereby making the mounting frame 7 more stable when the potassium chloride solution passes through it. At the same time, the sealing gaskets are fixedly installed at the connection between the mounting frame 7 and the outer surface of the mounting groove 6, which can effectively prevent the potassium chloride solution from flowing out of the mounting groove 6 into the outside of the purification chamber 1.

[0036] like Figure 4 As shown, this invention illustrates a potassium chloride solution purification device in another embodiment. The cleaning mechanism includes a support plate 21, a water storage tank 22, an inlet pipe 23, a first annular pipe 24, a first spray head 25, a second annular pipe 26, a second spray head 27, a first connecting pipe 28, a water pump 29, and a second connecting pipe 30. The support plate 21 is fixedly installed on the outer left wall of the purification chamber 1. The water storage tank 22 is fixedly installed on the top of the support plate 21, and the inlet pipe 23 is fixedly installed on the top of the water storage tank 22. The first annular pipe 24 and the second annular pipe 26 are fixedly installed on the top of the pretreatment chamber 2 and the purification chamber 1, respectively. Several sets of first spray heads 25 are fixedly installed at the bottom of the first annular pipe 24, and the spray direction of each set of first spray heads 25 is towards the inner wall of the pretreatment chamber 2. Several sets of second spray heads 27 are fixedly installed at the bottom of the second annular pipe 26, and the spray direction of each set of second spray heads 27 is towards the inner wall of the purification chamber 1.

[0037] In some examples, after the potassium chloride solution has been purified using this device, the operator can not only remove the mounting bracket 7 from the purification chamber 1 for cleaning, but also start the water pump 29 via the control panel 33. This allows water to be pumped through the second connecting pipe 30 and the first connecting pipe 28 into the first annular pipe 24 and the second annular pipe 26. The water can then be sprayed out through the first spray head 25 and the second spray head 27 to rinse the inner walls of the pretreatment chamber 2 and the purification chamber 1. This reduces the impact of impurities adhering to the inner walls on the subsequent use of the device, and also improves the purification efficiency of the device to a certain extent, making the device more practical.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
