Description

Technical Field

[0001] The utility model relates to impurity removal equipment for salt heat treatment, belonging to the field of edible salt processing. Background Art

[0002] Edible salt can be classified into well salt, sea salt, pond salt, rock salt, etc. Its ingredients include iron, calcium, zinc, potassium, sodium, iodine and other nutrients. The edible salt people use is a type of salt, which refers to salt rich in sodium, that is, sodium chloride. Salt is also an important element that the human body cannot lack, and it has the function of regulating human activities.

[0003] The thermal treatment of sea salt is a process that uses solar energy to heat seawater and allow the water to slowly evaporate so that the concentration of sodium and chloride ions continues to rise. This process usually needs to be carried out on sunny days, especially in hot summer. After evaporation, tiny crystalline particles are left behind; these crystals are eventually collected and become the common table salt we know, and are then dried and screened.

[0004] Since the raw material is seawater, which contains not only sodium and chloride ions but also other debris, such as sawdust, seaweed, kelp and other aquatic plants, edible salt has requirements for the purity of sea salt, so it needs to be filtered and removed during heat treatment.

[0005] Therefore, the utility model provides a salt heat treatment impurity removal device which can quickly filter and remove impurities. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide a salt heat treatment impurity removal device which can quickly filter and remove impurities.

[0010] It also includes a screen and a first discharge port. The screen is embedded in the annular support bar by snapping. The shell on the horizontal side of the screen is provided with a first discharge port for impurities to discharge. The bottom surface of the first discharge port is flush with the top surface of the screen, and the thickness of the end of the screen close to the first discharge port is greater than that of the other end.

[0011] As a further improvement, the thickness L of the screen near the first discharge port is . times to times the thickness L at the other end.

[0012] As a further improvement, the screen comprises a surrounding frame and a metal mesh, and the metal mesh is fixed on a first surface of the surrounding frame.

[0013] As a further improvement, arc-shaped notches are provided at equal distances on the second surface of the surrounding frame;

[0014] An arc-shaped fixing column is welded on the support bar corresponding to the arc-shaped notch;

[0015] The arc-shaped notch and the arc-shaped fixing column are movably engaged.

[0016] As a further improvement, the number of the arc-shaped notches and the arc-shaped fixing columns is an even number.

[0017] As a further improvement, the metal mesh is drawn from a whole piece of metal plate.

[0018] As a further improvement, it also includes a frame, springs, and a vibration motor. There are several springs, and the vibration bin is fixed to the frame by the several springs. The vibration motor is located at the bottom of the vibration bin, and the output end of the vibration motor is mechanically connected to the bottom surface of the vibration bin.

[0021] As a further improvement, a plurality of moving wheels are locked at the bottom of the frame by a plurality of screws.

[0022] The beneficial effects of the utility model are:

[0023] ① The utility model pours the solution of salt during heat treatment from the feed port at the top of the shell into the impurity removal chamber, the impurities in the solution are blocked by the screen, and the remaining solution flows out directly from the screening chamber. Since the thickness of the end of the screen close to the first discharge port is greater than that of the other end, the solution from top to bottom will not be blocked by the screen at the moment, and the splashed solution will not easily flow out from the first discharge port.

[0024] ② The first surface of the screen of the utility model is inclined horizontally downward at an angle less than 45°, and the solution can be filtered relatively vertically downward. However, the splashed solution will not flow out from the first discharge port due to the inclination angle. The impurities can be gradually vibrated out under the vibration of the vibration motor due to the small inclination gradient, thereby improving the solution impurity removal efficiency of salt during heat treatment.

[0025] ③ The screen of the utility model is directly engaged from top to bottom because the salt solution is flushed directly from top to bottom. This downward flushing force makes it more firmly installed.

[0026] ④ The vibration motor drives the vibration bin to vibrate up and down on the frame. On the one hand, the impurities on the screen are directly shaken off to the first discharge port to facilitate the falling of the impurities. On the other hand, the impurities above and below the screen vibrate up and down and will not block the screen holes that pass through from top to bottom. BRIEF DESCRIPTION OF THE DRAWINGS

Since the thickness of the end of the screen 132 close to the first discharge port 133 is greater than that of the other end, the solution from top to bottom will not be blocked by the screen 132 at the moment, and the splashed solution will not easily flow out from the first discharge port 133.

[0039] Furthermore, the thickness L2 of the screen 132 near the first discharge port 133 is 1.5 to 2 times the thickness L2 at the other end, that is, the first surface 132-3 of the screen 132 is inclined horizontally downward at an angle less than 45°, and the solution can be filtered relatively vertically downward, but the splashed solution will not flow out from the first discharge port 133 due to the inclination angle, while the impurities can be gradually vibrated out under the vibration of the vibration motor due to the small inclination slope, thereby improving the solution impurity removal efficiency of the salt during heat treatment.
