Description

Technical Field

[0001] This utility model relates to the field of potassium chloride production technology, and in particular to an evaporation and concentration device for potassium chloride production. Background Technology

[0002] The production process of potassium chloride mainly includes mining, beneficiation, dissolution, purification, crystallization, centrifugal dehydration, and drying. The main production processes of potassium chloride include cold decomposition-flotation, reverse flotation-cold crystallization, and brine mixing.

[0003] Existing patent CN219050331U discloses a special sampling device for environmentally friendly water body testing. This utility model includes a workbench, a drive mechanism is provided inside the workbench, an evaporation and concentration device is slidably connected to the inner surface of the workbench, the evaporation and concentration device cooperates with the drive mechanism, a control device is provided inside the evaporation and concentration device, and a condensation device is fixedly connected inside the evaporation and concentration device. This device can prevent the steam generated by evaporation from condensing on the inner wall of the evaporation device and flowing back into the potassium chloride solution, thereby improving the evaporation and concentration efficiency of potassium chloride.

[0004] However, although the existing patent CN219050331U can prevent the steam generated by evaporation from condensing and flowing back into the potassium chloride solution on the inner wall of the evaporation device, thereby improving the evaporation and concentration efficiency of potassium chloride, a layer of potassium chloride crystals may adhere to the inner wall after the potassium chloride is evaporated and concentrated, which is difficult to clean.

[0005] Therefore, we propose an evaporation and concentration device for potassium chloride production. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an evaporation and concentration device for potassium chloride production.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An evaporation and concentration device for potassium chloride production includes an evaporation reaction cylinder. A cylinder cover is provided at the top of the evaporation reaction cylinder, and a support frame is fixedly provided at the bottom of the evaporation reaction cylinder. An insulating sleeve is fixedly provided at the top of the evaporation reaction cylinder. An electric heating device is fixedly provided on the side of the insulating sleeve away from the cylinder cover. The output end of the electric heating device passes through the insulating sleeve into the interior of the evaporation reaction cylinder. A heat dissipation mesh is fixedly provided at the top of the cylinder cover. A cleaning component is provided on one side of the evaporation reaction cylinder, and a servo motor is provided on one side of the evaporation reaction cylinder. The transmission end of the servo motor is fixedly connected to a first synchronous pulley.

[0009] As a further embodiment of this invention: the first synchronous pulley is disposed inside the evaporation reaction cylinder, and one side of the first synchronous pulley is meshed with the second synchronous pulley.

[0010] As a further improvement of this utility model: the bottom of the second synchronous pulley is fixedly connected to the lead screw, and a positioning nut is provided on the outer side of the lead screw.

[0011] As a further improvement of this utility model: a connecting rod is fixedly provided on the outside of the positioning nut, and an annular scraper is fixedly provided on the side of the connecting rod away from the positioning nut.

[0012] As a further improvement of this utility model: the annular scraper is disposed on the inner side of the evaporation reaction cylinder, and a scale is fixedly disposed on the outer side of the evaporation reaction cylinder.

[0013] As a further improvement of this utility model: the diameter of the annular scraper is about 30-50cm, and the outer side of the annular scraper is fixedly provided with diagonal lines.

[0014] Compared with the prior art, this utility model provides an evaporation and concentration device for potassium chloride production, which has the following advantages:

[0015] 1. This utility model, through the installation of a cleaning component, uses an electric heating device to heat the interior of the evaporation reaction cylinder. The electric heating device converts electrical energy into heat energy to heat the solution inside the evaporation reaction cylinder. The electric heater converts electrical energy into heat energy, raising the temperature of the solution inside the evaporation reaction cylinder. As the temperature rises, the water in the solution begins to evaporate, forming steam. This heating method is characterized by high efficiency, precise temperature control, and environmental friendliness. It promotes the evaporation and concentration of potassium chloride inside the evaporation reaction cylinder. The scale markings facilitate observation of changes in the amount of potassium chloride inside the evaporation reaction cylinder, helping to monitor the reaction process in real time, ensuring process stability and product quality. The scale markings are particularly important in the evaporation and concentration of industrial wastewater containing sodium chloride and potassium chloride. By observing the scale markings, operators can promptly understand the changes in the concentration of potassium chloride in the concentrated liquid, thereby adjusting the evaporation and concentration parameters to ensure that potassium chloride reaches a saturated dissolved state. The heat dissipation mesh is used to dissipate heat from inside the device, effectively improving the convenience of the device.

[0016] 2. In this invention, after the device evaporates and concentrates potassium chloride, the servo motor starts, driving the first synchronous pulley to rotate, which in turn drives the second synchronous pulley to rotate, causing the lead screw to rotate. This causes the positioning nut to move up and down, moving the annular scraper up and down along the side wall of the evaporation reaction cylinder to scrape off the potassium chloride crystals remaining on the inner wall of the evaporation reaction cylinder, facilitating cleaning. The diagonal design of the annular scraper increases the friction between the annular scraper and the inner wall of the evaporation reaction cylinder. The up and down movement of the annular scraper along the side wall of the evaporation reaction cylinder ensures that the potassium chloride crystals are effectively scraped off, preventing the accumulation of potassium chloride crystals on the inner wall of the evaporation reaction cylinder, which would affect the evaporation efficiency and product quality, and effectively improving the convenience of the device.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example: An evaporation and concentration device for potassium chloride production includes an evaporation reaction cylinder 1, a cylinder cover 2 at the top of the evaporation reaction cylinder 1, a support frame 3 fixedly installed at the bottom of the evaporation reaction cylinder 1, an insulating sleeve 4 fixedly installed at the top of the evaporation reaction cylinder 1, an electric heating device 5 fixedly installed on the side of the insulating sleeve 4 away from the cylinder cover 2, the output end of the electric heating device 5 passing through the insulating sleeve 4 into the interior of the evaporation reaction cylinder 1, and a heat dissipation mesh 6 fixedly installed at the top of the cylinder cover 2.

[0026] like Figures 1-4 As shown, a cleaning component 7 is installed on one side of the evaporation reaction cylinder 1, and a servo motor 71 is installed on the other side. The transmission end of the servo motor 71 is fixedly connected to a first synchronous pulley 72, which is located inside the evaporation reaction cylinder 1. One side of the first synchronous pulley 72 is meshed with a second synchronous pulley 73, and the bottom of the second synchronous pulley 73 is fixedly connected to a lead screw 74. A positioning nut 75 is installed on the outside of the lead screw 74, and a connecting rod 76 is fixedly installed on the outside of the positioning nut 75. An annular scraper 77 is fixedly installed on the side of the connecting rod 76 away from the positioning nut 75. The annular scraper 77 is located inside the evaporation reaction cylinder 1, and a scale mark 8 is fixedly installed on the outside of the evaporation reaction cylinder 1. The diameter of the annular scraper 77 is approximately 30-50 cm, and the outer side of the annular scraper 77 is fixedly provided with diagonal lines. During the evaporation and concentration process, the electric heating device 5 heats the interior of the evaporation reaction cylinder 1 to promote the evaporation and concentration of potassium chloride inside the evaporation reaction cylinder 1. The scale mark 8 facilitates the observation of changes in the amount of potassium chloride inside the evaporation reaction cylinder 1. The heat dissipation mesh 6 is used to dissipate heat from inside the device. After the device evaporates and concentrates potassium chloride, the servo motor 71 starts, driving the first synchronous pulley 72 to rotate, which in turn drives the second synchronous pulley 73 to rotate, causing the lead screw 74 to rotate. This causes the positioning nut 75 to move up and down, which in turn drives the annular scraper 77 to move up and down along the side wall of the evaporation reaction cylinder 1 to scrape off the potassium chloride crystals remaining on the inner wall of the evaporation reaction cylinder 1, facilitating cleaning. The up and down movement of the annular scraper 77 along the side wall of the evaporation reaction cylinder 1 ensures that potassium chloride crystals are effectively scraped off, preventing them from accumulating on the inner wall and thus affecting evaporation efficiency and product quality.

[0027] Working principle: When using the evaporation and concentration device for potassium chloride production, the electric heating device 5 heats the inside of the evaporation reaction cylinder 1, promoting the evaporation and concentration of potassium chloride inside the evaporation reaction cylinder 1. The scale mark 8 is set to facilitate the observation of changes in the amount of potassium chloride inside the evaporation reaction cylinder 1. The heat dissipation mesh 6 is set to dissipate heat from inside the device. After the device evaporates and concentrates potassium chloride, the servo motor 71 starts, driving the first synchronous pulley 72 to rotate, causing the second synchronous pulley 73 to rotate, driving the lead screw 74 to rotate, causing the positioning nut 75 to move up and down, driving the annular scraper 77 to move up and down along the side wall of the evaporation reaction cylinder 1, scraping off the potassium chloride crystals remaining on the inner wall of the evaporation reaction cylinder 1, facilitating cleaning. The up and down movement of the annular scraper 77 along the side wall of the evaporation reaction cylinder 1 can ensure that potassium chloride crystals are effectively scraped off, preventing them from accumulating on the inner wall, thereby affecting evaporation efficiency and product quality.
