Abstract
Description
A screw-propelled intelligent dosing device for high-viscosity concentrates Technical Field
[0001] This invention relates to the field of fluid transport technology, and in particular to a spiral propulsion intelligent dosing device for high-viscosity concentrates. Background Technology
[0002] High-viscosity concentrates, such as polymer flocculants, polymer solutions, syrups, high-concentration ointments, and adhesives, are widely used in chemical, pharmaceutical, and environmental water treatment fields. Due to their high solid content, long molecular chains, or special formulations, these liquids exhibit significant physical characteristics such as high viscosity, easy adhesion to walls, and poor fluidity. Their dosing process usually requires precision, uniformity, and stability to ensure reaction efficiency, product quality, or treatment effect.
[0003] Existing dosing devices, when dealing with high-viscosity solutions, often result in the solution sticking and adhering to the tank or conveying pipeline walls due to its viscous consistency and lack of flow. This leads to residual active ingredients, inaccurate metering, and material waste. Conventional pumping or gravity-feeding methods are insufficient for the continuous and controllable delivery of high-viscosity solutions, and are prone to clogging or uneven dispensing, affecting process stability and operational efficiency. Therefore, this invention proposes a spiral-propelled intelligent dosing device for high-viscosity concentrates. Summary of the Invention
[0004] Therefore, in order to overcome the common problems of high-viscosity concentrates easily sticking to the wall, uneven delivery, and easy clogging during the dosing process.
[0005] The technical solution of the present invention is as follows: a spiral propulsion intelligent dosing device for high viscosity concentrate, comprising a dosing tank, a support frame, and a dosing pipe. The dosing pipe is composed of large and small rings and a connecting plate. The dosing tank is installed inside the large ring of the support frame, and the dosing pipe is installed inside the small ring of the support frame. The dosing tank and the dosing pipe are connected and installed in communication. A stirring component is provided inside the dosing tank, and a pushing component is installed inside the dosing pipe.
[0006] Preferably, the top of the dosing tank is provided with a dosing port, and the bottom extension of the dosing tank and the bottom extension of the dispensing pipe are both provided with limit holes, and limit bolts are inserted into the limit holes.
[0007] Preferably, the stirring assembly includes a drive motor, which is fixedly installed on the outer wall of the top of the dosing tank, and the output end of the drive motor is connected to a rotating shaft. A first connecting rod and a second connecting rod are symmetrically fixed to the outer wall of the rotating shaft. A first scraper and a second scraper are fixed to the ends of the first connecting rod and the second connecting rod. The blades of the first scraper and the second scraper are both in contact with the inner wall of the dosing tank, and the first scraper is set higher than the second scraper.
[0008] Preferably, a screw is fixed to the end of the rotating shaft, and the screw extends into the drug outlet tube.
[0009] Preferably, the pushing component includes a mounting base disposed inside the dispensing tube, with support legs symmetrically fixed to the side wall of the mounting base, the end of the support leg away from the mounting base being fixed to the inner wall of the dispensing tube, and the end extension of the screw being rotatably mounted on the top outer wall of the mounting base.
[0010] Preferably, a sleeve is slidably installed inside the mounting base, a hollow column is fixedly connected to the bottom end of the sleeve, and a support spring is sleeved on the outside of the sleeve. One end of the support spring is fixedly connected to the inner wall of the top end of the sleeve, and the other end of the support spring is fixedly connected to the inner wall of the bottom end of the mounting base.
[0011] Preferably, the side wall of the dispensing tube is connected to a connecting pipe, a piston column is installed inside the connecting pipe, and an electric push rod is fixedly installed on the side wall of the support frame. The extended end of the electric push rod passes through the connecting pipe and is coaxially connected to the piston column.
[0012] The beneficial effects of this invention are as follows: During use, the dosing device drives the rotating shaft and scraper assembly to rotate continuously via a drive motor. This causes the scraper to closely adhere to the inner wall of the dosing tank, scraping away high-viscosity liquid that has adhered to the tank wall due to long-term stagnation, preventing material from sticking to the wall and leaving residue. This ensures uniform composition of the liquid and accurate dosing. Furthermore, during use, the screw continuously rotates and presses the liquid downwards, pushing the hollow column downwards to overcome spring resistance and connect and seal the conveying passage. Subsequently, an electric push rod drives a piston to quantitatively extract the liquid, achieving directional delivery and precise metering of high-viscosity liquid, thus ensuring the continuity and controllability of the dosing process.

[0020] The top of the dosing tank 1 is provided with a dosing port 101. The bottom extension of the dosing tank 1 and the bottom extension of the dosing pipe 3 are both provided with a limiting hole 102. A limiting bolt 103 is inserted into the limiting hole 102.
[0021] An observation window is provided on the side wall of the dosing tank 1.
[0022] The stirring assembly 4 includes a drive motor 401, which is fixedly installed on the outer wall of the top of the dosing tank 1. The output end of the drive motor 401 is connected to a rotating shaft 402. A first connecting rod 403 and a second connecting rod 404 are symmetrically fixed to the outer wall of the rotating shaft 402. A first scraper 405 and a second scraper 406 are fixed to the ends of the first connecting rod 403 and the second connecting rod 404. The blades of the first scraper 405 and the second scraper 406 are both in contact with the inner wall of the dosing tank 1, and the first scraper 405 is set higher than the second scraper 406.
[0023] A screw 407 is fixed to the end of the rotating shaft 402, and the screw 407 extends into the medicine outlet tube 3.
[0024] The push component 5 includes a mounting base 501, which is located inside the drug outlet tube 3. Support legs 502 are symmetrically fixed to the side wall of the mounting base 501. The end of the support leg 502 away from the mounting base 501 is fixed to the inner wall of the drug outlet tube 3. The end extension of the screw 407 is rotatably mounted on the top outer wall of the mounting base 501.
[0025] A sleeve 503 is slidably installed inside the mounting base 501. A hollow column 504 is fixed to the bottom end of the sleeve 503. A support spring 505 is sleeved on the outside of the sleeve 503. One end of the support spring 505 is fixed to the inner wall of the top end of the sleeve 503, and the other end of the support spring 505 is fixed to the inner wall of the bottom end of the mounting base 501.
[0026] A connecting pipe 506 is provided on the side wall of the dispensing tube 3. A piston column 507 is installed inside the connecting pipe 506. An electric push rod 508 is fixedly installed on the side wall of the support frame 2. The extended end of the electric push rod 508 passes through the connecting pipe 506 and is coaxially connected to the piston column 507.
[0027] Working principle: Referring to Figures 1-5, when the device is in use, the drive motor 401 starts, driving the rotating shaft 402 to rotate. This drives the first scraper 405 and the second scraper 406 to scrape off the high-viscosity liquid that has adhered to the inner wall of the dosing tank 1 due to prolonged stagnation, preventing the liquid from sticking and accumulating on the tank wall. At the same time, the screw 407 at the end of the rotating shaft 402 rotates downwards, squeezing and pushing the liquid. The liquid gradually accumulates in the outlet pipe 3 and overcomes the elastic force of the support spring 505, pushing the sleeve 503 to move the hollow column 504 downwards, connecting the inside of the dosing tank 1 with the connecting pipe 506. At this time, the hollow column 504 blocks the lower half of the outlet pipe 3. The medicine outlet; as shown in Figures 3-5, the electric push rod 508 then moves inward, driving the piston rod 507 to draw out the medicine liquid that has been pressurized and pushed by the screw 407 in the connecting pipe 506. After the medicine liquid is drawn out, the support spring 505 restores its elasticity, pushing the sleeve pin 503 and the hollow column 504 to reset upward, reopening the outlet of the medicine outlet pipe 3. Then the electric push rod 508 pushes outward, accurately pushing out the medicine liquid temporarily stored in the connecting pipe 506 through the medicine outlet pipe 3, completing one quantitative medicine pushing process. Throughout the process, the drive motor 401 runs continuously, driving the scraper to continuously scrape off the medicine liquid from the tank wall, ensuring that the high viscosity concentrate flows evenly and does not stick.
[0028] It should be noted that the aforementioned drive motor 401 and electric push rod 508 can be powered by existing operating techniques, whether using a power supply unit or an external wire, both of which are conventional operating techniques and will not be described in detail here.
[0029] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
