Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and more specifically relates to a solid-liquid isolation type liquid medicine preparation system. Background Art

[0002] In sewage treatment, the addition of chemicals is common in all water treatment links, and most of the chemicals added are flocculation and coagulant chemicals. This type of chemical is mostly powder particles, which are easy to coagulate, easy to agglomerate, and not easily soluble in water. The direct addition effect is poor and cannot achieve the treatment effect. This type of chemical must first be adjusted into a liquid and then added to the treatment link as a liquid.

[0003] Common drug dosing devices on the market are to manually add powder to the dry powder dosing machine, and then the dry powder dosing machine puts it into the dissolution box. The dissolution box is equipped with a mixer to promote its dissolution. After dissolution, it is transported to various processing links through the drug outlet pipeline. Common drug dosing devices on the market often face the following problems: powder is easy to agglomerate in the dry powder dosing machine, resulting in inaccurate drug output; after the dry powder is put into the dissolution box, it floats on the surface due to the tension of the water surface and is difficult to dissolve in water, resulting in inaccurate preparation amount; after the drug is dissolved in water, it sinks to the bottom of the water, and the ordinary mixer cannot fully stir it, so that the drug outlet is blocked, damage to the dosing pump, and overflow may occur.

[0004] After searching, there are related patents disclosed about the drug dissolving device, such as the Chinese patent application number: 201822134999.5, the authorization announcement date is September 20, 2019, and the name of the invention is: a drug dissolver. The application includes a cylinder for holding the drug, and an air stirring device is provided in the cylinder. The air stirring device includes an annular air blowing pipe and an air pressure pipe. One end of the air pressure pipe is connected to the annular air blowing pipe, and the other end extends outside the cylinder to be connected to the pulse air source. The upper and lower end surfaces of the annular air blowing pipe are provided with a plurality of blowing holes evenly distributed along the circumference thereof. The drug dissolver provided in the application performs dynamic stirring by injecting pulsed compressed air into the drug liquid in the drug barrel through the blowing holes evenly distributed on the annular air blowing pipe. Compared with traditional mechanical stirring and dissolving facilities, the dissolution effect of the agent can be improved. However, for agents that become damp and agglomerated, the dissolution effect of the agent is still relatively limited, and it is also difficult to solve the problem that the powdered agent floats on the surface due to the tension of the water surface after being put into the water and is difficult to dissolve in water.

[0047] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0048] The utility model is further described below in conjunction with specific embodiments.

[0049] Example 1

[0050] like Figure 1-2 As shown, this embodiment provides a solid-liquid isolation type liquid medicine preparation system, including a feeding device 1, a dosing device 3, a pre-dissolving device 4 and a drug dissolution promoting device 7, wherein:

[0051] The feeding device 1 adopts the existing vacuum suction equipment, and the top of the feeding device 1 directly sucks the solid medicine into the external medicine storage through the vacuum soft feeding pipe 101, which saves the manual dosing link, reduces the labor cost and eliminates the possibility of the medicine being contaminated by foreign matter. The feeding device 1 is connected with the dosing device 3, and the amount of solid medicine can be accurately controlled by setting the dosing device 3. In the prior art, since the solid powder medicine used for sewage treatment is usually mainly flocculation and coagulation medicine, it has the characteristics of easy coagulation, easy agglomeration, and difficult to dissolve in water. Generally, the solid powder medicine is weighed manually and then added to the dry powder dispenser, and then the dry powder dispenser puts the medicine into the medicine dissolving equipment for pre-dissolution, and finally configured into a liquid medicine, and transported to various sewage treatment links by the medicine outlet pipeline for use. However, the existing dry powder dispenser does not isolate the rising water vapor of the medicine dissolving equipment when adding powder medicine into the medicine dissolving equipment, which easily causes the powder to get damp and agglomerate in the dry powder dispenser. The agglomerated medicine has the following disadvantages:

[0052] 1) It hinders the subsequent addition of medicines, which not only affects the delivery effect of powder medicines, but also affects the amount of medicines added, resulting in inaccurate medicine addition and waste of medicines.

[0053] 2) Long-term agglomerated reagents are prone to blockage in the dry powder dosing machine, requiring frequent inspection and maintenance, with high labor costs.

[0054] 3) When the agglomerated medicine enters the medicine dissolution equipment for dissolution, it is difficult to be fully dissolved, which will block the dosing pipeline and deposit at the bottom of the medicine dissolution equipment, not only affecting the concentration of the medicine solution after preparation, but also the undissolved medicine particles are mixed in the medicine solution, which is particularly easy to block the liquid outlet when the medicine solution is discharged.

[0055] In order to solve the above problems, the structure of the existing dry powder dosing machine must be improved. The dosing device 3 of this embodiment is as follows: Figure 3 and Figure 4As shown, the dosing device 3 as a whole is an existing dry powder dosing machine structure, which is different from the existing conventional dry powder dosing machine structure in that: the dosing device 3 of this embodiment is also provided with a conveying trough body 301 extending into the interior of the pre-dissolving device 4, and an isolation baffle 302 can be flipped and installed at the end of the conveying trough body 301. The area of ​​the isolation baffle 302 is larger than the pipe mouth of the discharge port of the conveying trough body 301, and the top of the isolation baffle 302 is hinged to the top of the conveying trough body 301, and the isolation baffle 302 is close to the upper side wall of the discharge port of the conveying trough body 301, and is also connected to the conveying trough body 301 through a spring. When adding powdered medicine, the conveying device of the dosing device 3 continuously transports the powder medicine toward the discharge port of the conveying trough body 301, and after reaching the discharge port, the isolation baffle 302 is pushed open to discharge the material. After the discharge is completed, the isolation baffle 302 is affected by the spring and resets again. By setting the isolation baffle 302, water vapor can be effectively blocked from entering the dosing device 3, thereby preventing the solid powder medicine from solidifying and agglomerating due to the influence of water vapor.

[0056] More optimally, as a further improvement of this embodiment, in the prior art, the solid powdered medicine delivered by the dry powder feeder is directly put into the medicine dissolving device for dissolution. Since the powdered medicine is easily floated on the surface due to the tension of the water surface after being put in, it is difficult to dissolve in water quickly, resulting in the medicine concentration failing to reach the target value. Therefore, this embodiment further provides a pre-dissolving device 4 of a new structure, specifically, as Figure 1 , Figure 3 and Figure 5-7 As shown:

[0057] The pre-dissolving device 4 includes a pre-dissolving body 402 connected to a water inlet pipe 5, and the water inlet pipe 5 feeds water into the pre-dissolving body 402 along a tangential direction. The tangential water feeding can cooperate with the structural design inside the pre-dissolving body 402 to form a rotating spiral water curtain, which can make the solid powdered medicine falling into the pre-dissolving body 402 swirl and fully contact with water, thereby increasing the contact area and contact effect between the medicine and water, accelerating the dissolution of the medicine, and significantly improving the dissolution sufficiency of the medicine. The prepared medicine liquid has a uniform concentration and does not contain undissolved medicine particles, which effectively prevents the solid medicine from floating on the water surface and affecting the concentration of the medicine, and further reduces the phenomenon of medicine agglomeration and deposition, thereby avoiding the problem of blockage of the liquid outlet.

[0058] like Figure 3 and Figure 7As shown, the pre-dissolving body 402 is processed with a feed trough body 4021, a pre-dissolving trough body 4022 and a liquid outlet channel 405 in sequence, wherein the feed trough body 4021 is connected to the discharge port of the conveying trough body 301, the inner wall of the pre-dissolving trough body 4022 is processed into a funnel-shaped structure that is wide at the top and narrow at the bottom, and the liquid outlet channel 405 arranged at the bottom of the pre-dissolving trough body 4022 is connected to the drug dissolution-promoting device 7, and the drug liquid dissolved in the pre-dissolving body 402 enters the drug dissolution-promoting device 7 from the liquid outlet channel 405 for further stirring and dissolution.

[0059] In addition, more optimally, in order to facilitate the connection between the water inlet pipe 5 and the pre-dissolving body 402, a liquid inlet pipe 403 is further provided in the present embodiment, and the liquid inlet pipe 403 is arranged along the tangent direction of the pre-dissolving body 402, and one end of the liquid inlet pipe 403 is connected to the feeding tank body 4021 and the pre-dissolving tank body 4022, and the other end extends to the outside of the feeding tank body 4021 and the pre-dissolving tank body 4022 and is connected to the water inlet pipe 5, thereby effectively ensuring that the water inlet of the pre-dissolving body 402 can form a rotating water inlet, and cooperates with the setting of the funnel-shaped inner side wall of the pre-dissolving body 402 that is wide at the top and narrow at the bottom, thereby forming a rotating spiral water curtain, which can fully improve its contact with the solid powdered material.

[0060] Example 2

[0061] like Figure 1 , Figure 3-4 As shown, the structure of the solid-liquid isolation type liquid medicine preparation system of this embodiment is basically the same as that of embodiment 1, and the difference between it and embodiment 1 is that it also includes a storage device 2, and the storage device 2 is arranged between the feeding device 1 and the dosing device 3. Specifically, the storage device 2 can adopt the existing storage equipment, and the dosing device 3 is installed on the storage device 2. Through the setting of the storage device 2, the solid medicine delivered by the feeding device 1 can be temporarily stored. When the medicine needs to be added, the dosing device 3 can be opened to discharge the material. In addition, a rotary level meter 201 is also provided in the storage device 2, which can detect and display the storage amount of the solid medicine in the storage device 2 in real time.

[0062] Example 3

[0063] The solid-liquid isolation type liquid medicine preparation system of this embodiment has a main structure similar to that of Embodiment 2, and the difference between it and Embodiment 2 is that: Figure 5As shown, the pre-dissolving device 4 further includes an isolation cover 401, which is detachably mounted above the pre-dissolving body 402. The isolation cover 401 is made of a transparent material, such as a transparent acrylic plate, which not only meets the requirement of transparency but also has a certain strength. At the same time, an assembly port 4011 is processed on the side wall of the isolation cover 401 for the conveying trough body 301 of the dosing device 3 to penetrate. The setting of the isolation cover 401 can effectively prevent the medicine from splashing out during the pre-dissolving process, and the isolation cover 401 made of a transparent material is also convenient for real-time observation of the pre-dissolving state of the medicine.

[0064] In addition, a mounting plate 404 is provided on the outer side wall of the pre-dissolving body 402, and mounting holes are processed at the four corners of the mounting plate 404. The entire pre-dissolving body 402 can be installed on the shell of the drug dissolution-promoting device 7 by screws, thereby completing the detachable installation of the pre-dissolving body 4.

[0065] As a further improvement of this embodiment, in order to facilitate the installation and disassembly of the isolation cover 401, a partition 4023 is provided in the middle of the feed trough body 4021 of the pre-dissolution main body 402, and a bayonet is processed at the connection between the partition 4023 and the feed trough body 4021, the bayonet and the bottom of the isolation cover 401 are snap-connected, and a feed port 4024 is processed in the middle of the partition 4023, and the discharge port of the conveying trough body 301 is arranged above the feed port 4024.

[0066] Example 4

[0067] like Figure 1-2 As shown, the solid-liquid isolation type liquid medicine preparation system of this embodiment has a main structure that is basically the same as that of Embodiment 3, and the difference between it and Embodiment 3 is that the medicine dissolution promoting device 7 comprises a medicine dissolution tank 701, a medicine maturation tank 702 and a liquid medicine storage tank 703 that are connected in sequence. After the solid powder medicine is fully contacted with water in the pre-dissolution device 4, it enters the medicine dissolution tank 701, the medicine maturation tank 702 and the liquid medicine storage tank 703 in sequence, and finally is discharged from the liquid medicine discharge pipe 6.

[0068] More optimally, in the present embodiment, the medicine dissolving box 701, the medicine maturing box 702 and the medicine liquid storage box 703 are all provided with a cyclone 8, which can push from top to bottom to form a cyclone, effectively drive the solution in a single box to move, and fully dissolve the medicine. Since the density of the medicine itself is different from that of the water used for preparation, it is easy to settle at the bottom of the box if it is not fully mixed by pushing the flow. The setting of the cyclone 8 can make the solution form a cyclone, thereby effectively pushing the solution at the bottom of the box to the upper part, and preventing the precipitation of the medicine.

[0069] In addition, more optimally, a high-power cyclone 8 is set in the medicine dissolution box 701 and the medicine maturation box 702 to accelerate the dissolution of the medicine, and a low-power cyclone 8 is set in the medicine storage box 703 to push the solution in the box, which can effectively prevent the medicine solution from depositing and clogging the medicine outlet.

[0070] In addition, liquid level meters 9 are provided in the medicine maturation box 702 and the medicine liquid storage box 703, which can detect the liquid levels in the medicine maturation box 702 and the medicine liquid storage box 703 in real time.

[0071] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
