Description

Technical Field

[0001] The utility model relates to the technical field of soil remediation, in particular to a soil remediation stock solution stirring and mixing device. Background Art

[0002] Soil remediation is a technical measure to restore the normal function of polluted soil. In the soil remediation industry, there are more than 100 existing soil remediation technologies and more than 10 commonly used technologies, which can be roughly divided into three methods: physical, chemical and biological. Soil remediation agents are usually used in the soil remediation process. In the production process of soil remediation agents, different raw materials need to be mixed and stirred.

[0003] Since the soil is being repaired, the proportion of the repair liquid used for soil repair must be accurate in quantity, so as to achieve the expected effect. When the existing soil repair stock solution stirring and mixing device is mixing the various stock solutions used for the repair liquid, the stock solution is often poured into the mixing barrel and stirred directly before use. This often leads to improper stock solution proportions, making the repair effect of the repair liquid fail to achieve the expected effect. In addition, the mixing barrel needs to be sealed during the mixing and stirring process of the repair liquid to prevent the repair liquid from spilling during stirring. However, after the mixing barrel is sealed, the stirring fan blades used to stir the stock solution cannot be removed from the mixing barrel, resulting in the failure to replace it in a timely and effective manner when it is damaged over a long period of time. Utility Model Content

[0004] The utility model provides a soil remediation stock solution stirring and mixing device, which overcomes the shortcomings of the above-mentioned prior art and can effectively solve the problem of poor repair liquid mixing effect due to the lack of a quantitative mechanism in the existing soil remediation stock solution stirring and mixing device.

[0005] The utility model further solves the problem that the existing stirring mechanism is prone to damage due to long-term use because parts cannot be replaced.

[0006] In order to solve the above problems, the utility model discloses a soil remediation stock solution stirring and mixing device, which comprises a mixing barrel, a sealing cover, a quantitative mechanism, a lifting mechanism and a stirring mechanism;

A support plate is fixed symmetrically along the radial direction on the lower side of the outside of the mixing barrel, and a cylinder is provided above each support plate. The output ends of the two cylinders are connected to the lifting plate located above the mixing barrel. Clamping holes are provided on both sides of the lifting plate close to the cover, and a clamping pin matching the clamping hole is provided on the cover corresponding to the position of the clamping hole;

[0010] A stirring mechanism is arranged inside the mixing barrel, and the stirring mechanism includes a motor, a rotating shaft, a stirring blade and a spiral blade. A motor is arranged in the center above the lifting plate, and the output shaft of the motor passes through the lifting plate and is fixedly connected to the rotating shaft located inside the mixing barrel, and a stirring blade and a spiral blade are arranged outside the rotating shaft;

[0011] The bottom of the mixing barrel is fixedly connected with a drain pipe, and a stop valve is installed on the drain pipe.

A vertical bar is mounted on each cross bar, and the upper end of the vertical bar is located on the upper side of the mixing barrel. The spiral blade is arranged between the two vertical bars. A scraper is mounted on the side of each cross bar close to the bottom of the mixing barrel, and on the side of each vertical bar close to the wall of the mixing barrel.

[0028] A lifting mechanism is provided on the outside of the mixing barrel 1, and the lifting mechanism includes a support plate 7, a cylinder 8, a lifting plate 9, a clamping hole 10 and a clamping pin 11. The support plate 7 is fixed symmetrically along the radial direction on the lower side of the outside of the mixing barrel 1, and a cylinder 8 is provided above each support plate 7. The output ends of the two cylinders 8 are connected to the lifting plate 9 located above the mixing barrel 1. Clamping holes 10 are provided on both sides of the lifting plate 9 close to the cover 2, and a clamping pin 11 matching the clamping hole 10 is provided on the cover 2 corresponding to the position of the clamping hole 10;

[0029] A stirring mechanism is provided inside the mixing barrel 1, and the stirring mechanism includes a motor 12, a rotating shaft 13, a stirring blade 14 and a spiral blade 18. A motor 12 is provided in the center above the lifting plate 9, and the output shaft of the motor 12 passes through the lifting plate 9 and is fixedly connected to the rotating shaft 13 located inside the mixing barrel 1, and a stirring blade 14 and a spiral blade 18 are provided outside the rotating shaft 13;

[0030] A drain pipe 21 is fixedly connected to the bottom of the mixing barrel 1 , and a stop valve 22 is installed on the drain pipe 21 .

[0031] Among them, the function of the mixing barrel 1 is to stir and mix the soil remediation liquid; the function of the cover 2 is to seal the mixing barrel 1; the metering barrel 3 can control the amount of the original liquid when the remediation liquid is proportioned, and the proportioned original liquid is poured into the inner side of the metering barrel 3 through the liquid inlet 4; the solenoid valve 5 controls the original liquid in the metering barrel 3 to enter the mixing barrel 1, and the scale line 6 on the metering barrel 3 can check the proportion of the original liquid in the metering barrel 3.

[0032] Among them, the support plate 7 is used to support the fixed cylinder 8, and the cylinder 8 can drive the lifting plate 9 to move up and down. The lifting plate 9 drives the motor 12 to move, and then drives the rotating shaft 13 connected to the output shaft of the motor 12 to move, and the stirring blades 14 and spiral blades 18 arranged on the outside of the rotating shaft 13 are taken out from the mixing barrel 1, which is convenient for cleaning and maintenance of the parts of the stirring mechanism; through the card hole 10 on the lifting plate 9 and the card pin 11 on the cover 2, it is convenient to connect the cover 2 with the lifting plate 9, which is convenient for disassembly.

[0033] As required, the measuring cylinder 3 is made of transparent material, such as polycarbonate, so that the amount of liquid in the measuring cylinder 3 can be easily checked.

[0034] like Figure 5 As shown, a mounting sleeve 15 is sleeved on the outer side of the lower part of the rotating shaft 13, and two cross bars 16 are symmetrically mounted on the mounting sleeve 15 along the radial direction. A vertical bar 17 with an upper end located on the upper side of the mixing barrel 1 is mounted on each cross bar 16, and a spiral blade 18 is arranged between the two vertical bars 17. A scraper 20 is mounted on the side of each cross bar 16 close to the bottom of the mixing barrel 1, and on the side of each vertical bar 17 close to the wall of the mixing barrel 1. By setting the scraper 20, the scraper 20 rotates to scrape off the original liquid stuck to the inner wall of the mixing barrel 1.

[0035] like Figure 1 As shown, at least two supporting legs 23 are provided at the bottom of the mixing barrel 1, and a wear-resistant pad 19 is provided under each supporting leg 23. Thus, the mixing barrel 1 is supported; and the stability of the supporting legs 23 can be improved by providing the wear-resistant pad 19.

[0036] The working process of this device is as follows:

[0037] When in use, the staff pours various stock solutions required for making soil remediation liquid into the measuring cylinder 3 through the liquid inlet hopper 4, determines the proportion according to the capacity displayed by the scale line 6, and then opens the solenoid valve 5 to transport the stock solution with the good proportion into the mixing barrel 1; turns on the motor 12 to drive the rotating shaft 13 to rotate, and the rotating shaft 13 drives the stirring blade 14 and the mounting sleeve 15 to rotate, thereby driving the cross bar 16 and the vertical rod 17 to rotate, and further drives the spiral blade 18 to rotate. The rotation of the spiral blade 18 makes the stock solution in the barrel evenly mixed, and the rotation of the vertical rod 17 and the cross bar 16 simultaneously drives the scraper 20 to rotate, scrapes off the stock solution sticky on the inner wall of the mixing barrel 1, so that the stock solution in the mixing barrel 1 is mixed more evenly. After the stirring and mixing is completed, the stop valve 22 is opened to discharge the repair liquid from the drain pipe 21; after long-term use, when the stirring blade 14 and the spiral blade 18 need to be repaired and replaced, the cover 2 can be removed from the lifting plate 9, and the cylinder 8 is opened to drive the lifting plate 9 to move upward, so that the stirring blade 14 and the spiral blade 18 are taken out of the mixing barrel 1.

[0038] In summary, the utility model controls the ratio of the repair liquid by setting a quantitative mechanism, thereby making the ratio of the repair liquid more accurate, thereby improving the repair effect of the repair liquid; at the same time, by setting a lifting mechanism connected to the stirring mechanism, the parts of the stirring mechanism can be repaired and replaced, avoiding the problem of damage to the stirring mechanism due to long-term use, thereby increasing the service life of the device.
