Description

Technical Field

[0001] The utility model relates to the technical field of mixing, for example, dissolving, emulsifying or dispersing, and in particular to a solid agent dissolving device for remediating contaminated sites. Background Art

[0002] Soil and groundwater remediation of contaminated sites is an emerging environmental protection field that has developed in China in the past decade, and the industry output value has grown to hundreds of billions of yuan per year. Soil and groundwater remediation technology is divided into two categories: ex situ remediation technology and in situ remediation technology, depending on whether the contaminated medium is transferred. Among them, in situ remediation technology has lower construction costs and less impact on the surrounding environment, making it a better choice. With the development of the industry and the gradual maturity of remediation technology, the defects of in situ remediation technology, such as long construction period and high technical requirements, have been greatly improved. At the same time, as the remaining contaminated sites have reduced construction period requirements, the requirements for in situ remediation technology have been further reduced, and the proportion of in situ remediation technology used has continued to increase.

[0003] According to the mechanism of action, in-situ remediation technology can be divided into redox technology, solidification / stabilization technology, leaching technology, microbial technology, etc. These technologies usually require the injection of agents into the ground during use, and chemical oxidation technology sometimes requires repeated injection of large amounts of agents. Since some chemical agents are in the form of solid particles or powders, they generally need to be dissolved in water before injection. Therefore, the dissolution of agents is often an indispensable construction process in the in-situ remediation of contaminated sites. Some solid agents involved in in-situ remediation technology will release heat or absorb heat during the dissolution process, affecting the dissolution rate, and thus affecting the normal in-situ injection operation. Some agents are also highly corrosive, so the dissolution operation of solid agents has higher requirements for the dissolution device; for the former, the problem can be solved by adding a stirring device or expanding the stirring device, but the cost is increased and the use is not convenient enough, while the latter needs to be achieved by limiting the materials of a specific dissolution device.

[0004] Taking into account the problems existing in the prior art, developing a device that can quickly dissolve solid drugs in large quantities and has a wide range of applications will become an important part of improving the efficiency of in-situ remediation technology. Utility Model Content

[0008] Preferably, the liquid outlet is arranged at the upper part of the outer wall, and the liquid inlet is arranged at the lower part of the outer wall; the projections of the liquid outlet and the liquid inlet on the horizontal plane are arranged on both sides of the dissolving tank.

[0017] The beneficial effects of the utility model are:

[0018] (1) Chemical agents can be prepared quickly. Different from the traditional stirring device, which usually takes 0.5h to 1h to prepare a barrel of agent because the stirring paddle rotates too fast, causing the liquid in the barrel to overflow easily and the solid or powdered agent is not easy to disperse in the same direction of water flow, resulting in a slow dissolution rate. The device is equipped with a flow disturbance mechanism, so that during the agent dissolution process, the liquid in the dissolution tank is in a turbulent state, so that the solid agent is easy to disperse and dissolves quickly. A heat treatment mechanism is further provided to adjust the output of the heat treatment mechanism according to the dissolution properties of the agent, thereby adjusting the temperature of the liquid in the dissolution tank and accelerating the dissolution of the agent, and finally shortening the agent dissolution time by more than 1 / 3.

[0019] (2) Wide application scope; during the dissolution process of the medicine, the temperature of the liquid in the dissolution tank can be adjusted by increasing or decreasing the temperature of the interlayer liquid in the dissolution tank, thereby avoiding the problem of boiling or overheating of the liquid in the dissolution tank, and is therefore suitable for dissolving medicines of various properties;

[0032] In the utility model, a heat treatment mechanism 1 is arranged outside the dissolving tank and connected to the liquid outlet 5 and the liquid inlet 6, and its use scenarios include but are not limited to:

[0033] For drugs such as citric acid that absorb heat when dissolved, the temperature of the fluid or semi-fluid in the interlayer can be increased during the dissolution process to achieve heating of the liquid in the dissolution tank, that is, the fluid or semi-fluid is heated by the heat treatment mechanism 1 and then introduced between the inner wall 2 and the outer wall 3;

[0034] For a dissolving agent such as sodium hydroxide that releases heat, the temperature of the fluid or semi-fluid in the interlayer can be reduced during the dissolution process to achieve moderate cooling of the liquid in the dissolution tank to avoid the problem of liquid boiling or overheating, that is, the fluid or semi-fluid is cooled by the heat treatment mechanism 1 and then introduced between the inner wall 2 and the outer wall 3;

[0035] The heat treatment mechanism 1 is a device that can increase or decrease the temperature, and those skilled in the art can set it according to their needs.

[0036] In the utility model, the heat treatment mechanism 1 can be provided with a control valve and a liquid pump based on demand to assist the introduction of fluid or semi-fluid into the space between the inner wall 2 and the outer wall 3 of the dissolving tank.

[0037] The thermal conductivity of the inner wall 2 is greater than 0; one or more supporting members 7 are provided between the inner wall 2 and the outer wall 3 .

[0038] In the utility model, the inner wall 2 of the dissolving tank is made of stainless steel, which is beneficial to the uniformity of the temperature of the liquid in the barrel and promotes the heat exchange between the medicine in the barrel and the interlayer liquid.

[0039] In the utility model, in the actual application process, the outer wall 3 of the dissolution tank is made of polypropylene. The polypropylene outer wall can reduce the heat diffused to the surrounding area during the dissolution process of the medicine, avoid burns caused by accidental contact with the barrel wall during operation, and is more suitable for integration into the integrated injection equipment.

[0040] In the utility model, in order to ensure the structural integrity of the inner wall 2 and the outer wall 3 and to achieve the best heat exchange effect for the fluid or semi-fluid between the inner wall 2 and the outer wall 3, one or more support members 7 are arranged between the inner wall 2 and the outer wall 3. The number of support members 7 can be adjusted based on the specifications of the dissolving tank to ensure that the relative position of the inner wall 2 and the outer wall 3 is stable and does not deform.

[0042] The flow disturbance mechanism includes a plurality of baffles 10 arranged on the inner wall 2 of the dissolution tank in cooperation with the stirring blades 9.

[0043] The stirring blades 9 and the baffles 10 are alternately arranged in the vertical direction and are both inclined.

[0044] The angle between the stirring blade 9 and the baffle 10 is greater than 0 and less than 180°.

[0045] In the utility model, the corresponding dissolving tank is generally provided with a stirring structure, which generally includes a central stirring rod 8 and a stirring blade 9 arranged around the lower part thereof; the stirring structure is generally driven by a motor, which is easily understood by those skilled in the art, and on this basis, it is understandable that a cover body 11 is provided in conjunction with the tank body of the dissolving tank to fix the horizontal position of the stirring blade.

[0046] In the utility model, a baffle 10 is provided in the dissolving tank in conjunction with the stirring paddle, which is generally a stainless steel plate and is staggered with the stirring blades 9. Taking the arrangement of two layers of stirring blades 9 as an example, the baffle 10 can also be provided in two layers, which are respectively located between the two layers of stirring blades 9 and on the upper stirring blades 9; when stirring begins, under the action of the stirring blades 9, the water flow will form a vortex with the stirring rod 8 as the center along the stirring direction, and the baffle 10 can suppress this phenomenon and form turbulence in the water body, so that the solid medicine entering the dissolving tank is easy to disperse and dissolves faster.

[0047] In the utility model, Figure 2 As shown, both the stirring blade 9 and the baffle 10 are designed with a certain inclination angle. The inclined stirring blade 9 can stir the liquid and form a vortex, while the inclination angle of the baffle 10 suppresses this tendency.

[0048] In the utility model, in actual application, two scrapers (not shown in the figure) can also be set at the bottom of the stirring rod 8. After the stirring tank is used for a long time, solid medicine will be deposited at the bottom, which can be automatically scraped off by the scraper; the scraping mouth of the scraper is generally designed to be a blunt tooth structure, which is not easy to scratch the inner wall 2 of the dissolving tank, and is also convenient for scraping off the deposited medicine.

[0049] The stirring rod 8 and the stirring blade 9 are hollow and spatially connected. The stirring rod 8 is provided with an air inlet, and the stirring blade 9 is provided with an air outlet 13 .

[0050] In the utility model, the stirring structure is set to be hollow, which can be bulged during the stirring process, and gas is discharged through the air outlet 13, so that sufficient stirring in the stirring tank can be achieved with small bubbles, and it can also be used to adjust the temperature of the liquid in the dissolving tank.

[0051] In the utility model, in order to further increase the turbulence effect, through holes 12 can be distributed on the baffle 10, so that during the dissolution and stirring process, small water columns pass through the through holes 12 to improve the stirring efficiency; in the specific implementation process, the through holes 12 can be evenly distributed and have equal inner diameters, or can be unevenly distributed and have non-equal inner diameters based on the different characteristics of the drug to be dissolved.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
