Description

Technical Field

[0001] This utility model relates to the field of drug delivery equipment technology, specifically to a three-unit drug delivery system. Background Technology

[0002] In many industrial production and environmental treatment processes, chemical dosing is a crucial step. For example, in water treatment, flocculants, disinfectants and other chemicals are added to purify water. In chemical production, various chemical auxiliaries are added precisely according to reaction requirements. In the printing and dyeing industry, the precise dosing of specific chemicals is also essential to ensure dyeing effect and quality.

[0003] Traditional dosing equipment can only perform simple storage and dosing of one type of agent in practical applications, which has low applicability. When multiple agents need to be used together or multiple concentrations need to be prepared, multiple devices need to work at the same time, which increases costs and workload. After the equipment is used, the staff cannot clean the inside of the equipment, which affects the next use.

[0004] Therefore, based on this, a design or technical improvement is proposed to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings and provide a triple dosing device.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A three-unit dosing device includes a dosing tank body. Two sets of partition plates are welded equidistantly to the inner side of the dosing tank body, and a mounting top plate is provided above the dosing tank body. Two sets of mounting blocks are symmetrically welded to the middle of the left and right sides of the dosing tank body. A second electric push rod is installed between the two sets of mounting blocks. The telescopic end of the second electric push rod is connected to the lower surface of the mounting top plate. Three sets of raw material storage tanks are provided on the upper surface of the mounting top plate, and the raw material storage tanks are equipped with an adjustment mechanism to adjust the feeding speed. A stirring mechanism is provided inside the dosing tank body to stir the raw materials inside the dosing tank body. A dosing mechanism is installed at the front end of the dosing tank body to add the mixed liquid medicine inside the dosing tank body to other required equipment.

[0008] Furthermore, the adjustment mechanism includes two sets of guide plates symmetrically welded in an inclined state inside the raw material storage box, and scale lines are opened on the inner side of the raw material storage box. A fixed slide rod and an adjustment plate are arranged below the two sets of guide plates. Two sets of fixed slide rods are provided. A first electric push rod is detachably installed on one side of the raw material storage box, and the telescopic end of the first electric push rod is connected to one side of the adjustment plate.

[0009] Furthermore, the stirring mechanism includes three sets of servo motors equidistantly mounted on the upper surface of the mounting plate. Each of the three sets of servo motors has a stirring rod mounted on its rotor end, and multiple sets of stirring blades are uniformly welded to the outer side of the stirring rod. Multiple sets of through holes are uniformly opened on the inner wall of the multiple sets of stirring blades. A positioning groove that mates with the lower end of the stirring rod is welded to the middle position of the bottom inner side of the dosing tank body. Three sets of liquid level gauges are correspondingly provided on the outer surface of the front end of the dosing tank body.

[0010] Furthermore, the dosing mechanism includes a three-way pipe installed at the front end of the dosing tank body, and three sets of control valves are correspondingly arranged above the three-way pipe. A dosing port is opened at the front end of the three-way pipe, and a connecting flange is welded to the front end of the dosing port. A metering pump is installed above the dosing port.

[0011] Furthermore, the inner wall of the mounting plate is provided with three sets of water inlets, and a cover plate is provided above the water inlets. A handle is welded to the upper surface of the cover plate, and a protrusion on the lower surface of the cover plate is embedded in the inner side of the water inlet.

[0012] Furthermore, multiple sets of fixing blocks are symmetrically welded to the left and right sides of the main body of the dosing tank, and limit rods are inserted into the inside of the fixing blocks.

[0013] Furthermore, the inner wall of the fixing block is provided with a through circular hole that cooperates with the limiting rod, and the upper end of the limiting rod is welded to the lower surface of the mounting top plate.

[0014] Compared with existing technologies, the beneficial effects of this solution are:

[0015] 1. The stirring rod and blades are driven by three sets of servo motors, and the inner wall of the stirring blades is provided with through holes. The chemicals are powerfully stirred inside the dosing tank. The designed through holes can enhance the fluidity and turbulence of the liquid, making the chemical mixture more uniform. At the same time, it reduces the resistance of the water flow to the stirring blades. The positioning groove welded to the bottom of the inner side of the dosing tank limits the bottom of the stirring rod, ensuring the stable rotation of the stirring rod. This avoids the stirring rod from shaking due to resistance during the stirring process, which would affect the stirring effect and significantly improve the efficiency of chemical dissolution and mixing.

[0016] 2. The guide plate, fixed slide bar, and adjusting plate inside the raw material storage box work together with the first electric push rod. The position of the adjusting plate can be precisely controlled by the first electric push rod, and the gap between the two sets of guide plates can be adjusted to control the amount of raw material falling. The operator can accurately control the feeding amount by observing the scale lines on the inside of the raw material storage box. At the same time, the raw material inside the storage box falls evenly and slowly into the dosing tank body for mixing, avoiding excessive accumulation and sedimentation of raw material at the bottom of the dosing tank body, which would lead to uneven mixing. The partition plate divides the inside of the dosing tank body into three sets of closed chambers. Different amounts of raw material can be added to the three sets of raw material storage boxes to achieve synergistic effects of different concentrations.

[0017] 3. When the staff needs to clean the inside of the equipment, the mounting top plate can be lifted upward by the two sets of second electric push rods, and the limit rod can be used to limit its movement to ensure stability. The staff can use a high-pressure water gun to rinse the inside of the mixing mechanism and the dosing tank. The cleaning wastewater can be discharged through the metering pump and the three-way pipe. Attached Figure Description

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] like Figures 1-4 The illustrated three-stage dosing device includes a dosing tank body 1. Two sets of partition plates 2 are welded equidistantly to the inner side of the dosing tank body 1, dividing it into three independent, sealed spaces for storing and mixing different concentrations. A mounting plate 4 is installed above the dosing tank body 1. Three sets of servo motors 5 are equidistantly mounted on the upper surface of the mounting plate 4, driving stirring rods 6 and stirring blades 7 for mixing. Stirring rods 6 are mounted on the rotor ends of all three sets of servo motors 5, and multiple sets of stirring blades 7 are uniformly welded to the outer side of the stirring rods 6. Multiple sets of through holes are uniformly formed on the inner wall of the stirring blades 7 to enhance liquid flowability and turbulence, resulting in more uniform mixing of the chemicals and effectively reducing the resistance of the water flow to the stirring blades. A positioning groove 3, welded to the middle of the bottom inner side of the dosing tank body 1 and engaging with the lower end of the stirring rod 6, limits the movement of the stirring rod 6, preventing violent shaking caused by water flow resistance.

[0026] In one embodiment, three sets of level gauges 10 are correspondingly provided on the outer surface of the front end of the dosing tank body 1, so that the staff can easily observe the liquid level inside the dosing tank body 1. Three sets of raw material storage boxes 15 are correspondingly welded above the mounting top plate 4 for storing the required raw materials. Two sets of guide plates 17 are symmetrically welded on the inner side of each of the three sets of raw material storage boxes 15 in an inclined state, so that the raw materials can fall into the interior of the dosing tank body 1. The inner side of the raw material storage box 15 is provided with scale lines for easy observation by the staff. Two sets of fixed slide rods 18 are provided below the two sets of guide plates 17 to limit the adjustment plate 19 and keep it moving horizontally. The front end of the adjustment plate 19 is set in an inclined state to facilitate better contact with the bottom of the guide plate 17. A first electric push rod 16 is detachably installed on one side of the raw material storage box 15 to push the adjustment plate 19 to move in parallel and adjust the gap between the two sets of guide plates 17, thereby adjusting the speed at which the raw materials fall.

[0027] In one embodiment, a three-way pipe 11 is installed at the front end of the dosing tank body 1 to guide the liquid inside the dosing tank body 1. Three sets of control valves 12 are correspondingly arranged above the three-way pipe 11 to control the corresponding pipes. A dosing port 13 is opened at the front end of the three-way pipe 11, and a connecting flange is welded to the front end of the dosing port 13 to facilitate the connection between the operator and external equipment. A metering pump 14 is installed above the dosing port 13. In conjunction with the three sets of control valves 12, the liquid at different positions inside the dosing tank body 1 can be transported to the outside to complete the dosing operation.

[0028] In one embodiment, the inner wall of the mounting top plate 4 is provided with three sets of water inlets 8, which facilitates the addition of water required for stirring into the dosing tank body 1 by the operator. A cover plate 9 is provided above the water inlet 8 to seal the dosing tank body 1 during the mixing process and prevent impurities in the air from entering the equipment. A handle is welded to the upper surface of the cover plate 9 to facilitate the disassembly of the cover plate 9 by the operator. The protrusion on the lower surface of the cover plate 9 is embedded in the inner side of the water inlet 8 to limit the cover plate 9 and prevent it from moving.

[0029] In one embodiment, two sets of mounting blocks 20 are symmetrically welded to the middle positions of the left and right sides of the dosing tank body 1. A second electric push rod 21 is installed between the two sets of mounting blocks 20. The telescopic end of the second electric push rod 21 is connected to the lower surface of the mounting top plate 4 and is used to push the mounting top plate 4 to move up and down. After it is raised, the operator can use a high-pressure water gun to rinse and clean the stirring mechanism and the interior of the dosing tank body 1.

[0030] In one embodiment, multiple sets of fixing blocks 22 are symmetrically welded to the left and right sides of the dosing tank body 1, and a limiting rod 23 is inserted into the inside of the fixing block 22. The inner wall of the fixing block 22 is provided with a through circular hole that cooperates with the limiting rod 23 to limit the limiting rod 23. The upper end of the limiting rod 23 is welded to the lower surface of the mounting top plate 4, and the lower end slides inside the fixing block 22 to limit the mounting top plate 4 and keep it moving up and down stably.

[0031] The specific workflow of this plan is as follows:

[0032] First, connect the equipment to the power supply. Operators can then inject different amounts or types of chemicals into the three independent chambers through the top opening of the raw material storage tank 15. The raw materials slide down the inclined guide plate 17 to the bottom, contacting the upper surface of the adjusting plate 19. The scale lines on the inner wall of the raw material storage tank 15 help operators observe the remaining amount of chemicals to ensure sufficient supply. The main body of the dosing tank 1 is divided into three groups of closed chambers by the partition plate 2. Then, open the cover 9 of the water inlet 8 and inject an appropriate amount of clean water into the three chambers through an external water source. The three sets of level gauges 10 allow observation of the contents of the corresponding chambers. The liquid level is controlled by a cover plate 9 sealed with a protrusion to prevent liquid from splashing out or impurities from entering during stirring. When feeding, the first electric push rod 16 is activated to push the adjusting plate 19 horizontally along the fixed slide rod 18, thus adjusting the gap at the bottom of the guide plate 17. The raw material falls into the corresponding chamber through the gap. Operators can adjust the gap size by controlling the distance the adjusting plate 19 moves. The gap size determines the feeding speed, enabling precise feeding and ensuring the raw material falls evenly and slowly into the dosing tank body 1 for mixing, preventing the raw material from accumulating and settling at the bottom of the equipment, which would affect the stirring efficiency. During stirring, the servo motor 5 drives the stirring rod 6 to rotate, which in turn drives the stirring blades 7 to stir the water flow, ensuring thorough mixing of the raw materials. The multiple sets of through holes on the inner wall of the stirring blades 7 enhance liquid turbulence, improve mixing efficiency, and reduce the resistance of the water flow to the stirring blades 7. The positioning groove 3 restricts the shaking of the stirring rod 6, ensuring stable stirring. During the dosing process, according to process requirements, the control valve 12 of the corresponding chamber is opened, and the metering pump 14 delivers the agent through the three-way pipe 11 to the dosing port 13 to complete the dosing operation. The connecting flange welded to the front end of the dosing port 13 facilitates the connection of external pipelines. To achieve precise dosing to the target location, the equipment can simultaneously open multiple control valves 12 to add different concentrations or types of agents. During cleaning and maintenance, the two sets of symmetrically arranged second electric push rods 21 are activated to push the mounting top plate 4 to rise slowly and vertically along the limit rod 23. The limit rod 23 slides within the fixed block 22 to ensure that the mounting top plate 4 is raised smoothly and avoids tilting. After the top plate is raised, the staff uses a high-pressure water gun to thoroughly rinse the stirring blades 7 and the inner wall of the chamber. The wastewater generated during the rinsing process is discharged through the metering pump 14 and the three-way pipe 11, which greatly improves work efficiency.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
