Description

Technical Field

[0001] This utility model relates to the technical field of pipeline backwashing devices, and in particular to a backwashing device for a chemical dosing pipeline. Background Technology

[0002] A backwashing device for chemical dosing pipelines is commonly used in industries such as water treatment, sewage treatment, and chemical treatment. Its purpose is to keep the chemical dosing system unobstructed, prevent pipeline blockage due to deposits or impurities, and thus ensure the normal dosing of chemicals and the efficient operation of the system. The backwashing device periodically cleans the pipelines to avoid scaling, sedimentation, or blockage, thereby improving the reliability and service life of the system.

[0003] Currently, most chemical dosing systems on the market use external tap water directly connected to the main pipeline for backwashing. This method has significant hidden dangers: after the chemical is added, the corrosive chemicals remaining in the pipeline will mix directly with the tap water, causing the tap water to be contaminated, affecting water quality safety, and may even cause environmental compliance issues. In addition, the mixing of chemicals and tap water will accelerate pipeline corrosion and shorten the service life of the equipment. After the backwashing of traditional backwashing devices, the residual pressure in the pipeline may cause the water to flow back to the pump, resulting in pressure loss, pump cavitation, or motor damage. Furthermore, manual water replenishment or non-constant liquid level design can easily lead to insufficient water level in the tank, interruption of the backwashing process, and frequent manual intervention, resulting in low efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a backwashing device for a drug dosing pipeline.

[0005] This utility model is achieved using the following technical solution: a backwashing device for a pharmaceutical dosing pipeline, comprising a fixed frame, a connecting rod fixedly connected inside the fixed frame, a support rod fixedly connected inside the connecting rod, a support plate fixedly connected inside the fixed frame, a support frame fixedly connected to the right side of the fixed frame, and a start button fixedly connected to the left side of the fixed frame, and further comprising:

[0006] A backflush mechanism, comprising a mounting bracket fixedly connected to the top of a support rod, with an external agent dosing system disposed above the mounting bracket;

[0007] An automatic water replenishment mechanism includes a water tank fixedly connected inside a fixed frame, and the water tank is equipped with a constant liquid level automatic water replenishment device.

[0008] As a further improvement to the above solution, a backwash water pump is fixedly connected inside the mounting bracket, and a backwash water pump inlet is fixedly connected to the left side of the backwash water pump.

[0009] Through the above technical solution, the backwash water pump is connected to the bottom outlet of the water supply tank through the water inlet on the left side, forming a closed water pumping path to ensure stable water flow and sufficient pressure, effectively removing chemical residues and impurities in the pipeline.

[0010] As a further improvement to the above solution, a backwash water pump outlet is fixedly connected to the right side of the backwash water pump, and a one-way check valve is fixedly connected to the right side of the backwash water pump outlet.

[0011] The above technical solution, which fixes the backwash water pump outlet to the one-way check valve, prevents backflow from causing pressure loss or equipment damage, and avoids chemical backflow into the water pump, thus extending the service life of the equipment.

[0012] As a further improvement to the above solution, the external agent dosing system is fixedly connected to the right side of the one-way check valve, and the external agent dosing system is fixedly connected to the top of the support frame.

[0013] With the above technical solution, the external chemical dosing system is fixed on the top of the support frame and connected to the backwash water pump outlet through a one-way check valve, ensuring that the backwash water flow is directly injected into the target pipeline, thereby improving the cleaning effect. The fixed design of the support frame enhances the stability of the device and avoids loosening or leakage of connections due to vibration.

[0014] As a further improvement to the above solution, an automatic water replenishment tank inlet is fixedly connected inside the water replenishment tank, a connecting frame is fixedly connected to the top inner wall of the water replenishment tank, and a constant liquid level automatic water replenishment device is fixedly connected to the right side of the automatic water replenishment tank inlet.

[0015] Through the above technical solution, the water inlet of the automatic water replenishment tank is fixedly connected to the constant liquid level automatic water replenishment device, so as to realize real-time water level monitoring and precise water replenishment, ensuring the continuity of the backwashing process. The connecting frame fixes the water inlet and the water inlet pipe to ensure the stability of water flow and avoid water replenishment interruption caused by pipeline vibration or water pressure fluctuation.

[0016] As a further improvement to the above solution, the right side of the constant liquid level automatic water replenishment device is fixedly connected to a water inlet pipe, and the bottom of the water replenishment tank is fixedly connected to a water replenishment tank outlet.

[0017] With the above technical solution, the water inlet pipe is connected to the right side of the constant liquid level device, and external tap water is replenished to the water tank through the water inlet, realizing stratified water replenishment and water level control, avoiding direct contact between the agent and tap water, and the design of the water outlet at the bottom of the water tank ensures that the water stored at the bottom of the tank is used first when pumping water, reducing the risk of sediment being sucked into the water pump.

[0018] As a further improvement to the above solution, the water inlet of the automatic water replenishment tank is fixedly connected inside the connecting frame, and the water inlet pipe is fixedly connected inside the connecting frame.

[0019] With the above technical solution, the water inlet of the automatic water replenishment tank and the water inlet pipe are both fixed inside the connecting frame. The rigid structure of the connecting frame reduces the impact of water flow on the pipe and improves the durability of the device.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This invention utilizes a backwash pump connected to the bottom outlet of the makeup water tank via an inlet, forming a closed pumping path. This ensures stable water flow and sufficient pressure, effectively removing residual chemicals and impurities from the pipeline. A one-way check valve prevents backflow that could cause pressure loss or equipment damage, while also preventing chemicals from seeping back into the pump, extending the equipment's lifespan. Furthermore, the makeup water tank maintains a certain height between the tap water inlet and the water level inside the tank, physically isolating residual chemicals from the dosing system from direct contact with external tap water, effectively preventing chemical contamination of the tap water. Layered water replenishment and level control achieve separation of chemicals and tap water, ensuring water supply safety and environmental compliance.

[0022] This utility model uses a constant liquid level automatic water replenishment device to detect the water level. When the liquid level is lower than the set value, the water inlet pipe can be opened to replenish external tap water through the water inlet and water inlet pipe, ensuring the continuity of the backwashing process. The connecting bracket fixes the water inlet and water inlet pipe to ensure the stability of the water flow and avoid water replenishment interruption caused by pipe vibration or water pressure fluctuation.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] Example:

[0032] Please combine Figure 1-5 This embodiment of a backwashing device for a pharmaceutical dosing pipeline includes a fixed frame 1, a connecting rod 11 fixedly connected inside the fixed frame 1, a support rod 12 fixedly connected inside the connecting rod 11, a support plate 13 fixedly connected inside the fixed frame 1, a support frame 14 fixedly connected to the right side of the fixed frame 1, and a start button 15 fixedly connected to the left side of the fixed frame 1. It also includes:

[0033] The recoil mechanism 2 includes a mounting bracket 201 fixedly connected to the top of the support rod 12, and an external agent dosing system 206 is provided above the mounting bracket 201.

[0034] Automatic water replenishment mechanism 3 includes a water replenishment tank 301 fixedly connected inside the fixed frame 1, and a constant liquid level automatic water replenishment device 304 is provided inside the water replenishment tank 301.

[0035] The mounting bracket 201 is internally fixedly connected to a backwash water pump 202, and the backwash water pump inlet 203 is externally fixedly connected to the left side of the backwash water pump 202.

[0036] The backwash water pump 202 is externally fixedly connected to the right side of the backwash water pump 202, and a one-way check valve 205 is fixedly connected to the right side of the backwash water pump outlet 204.

[0037] The external chemical dosing system 206 is fixedly connected to the right side of the one-way check valve 205 and to the top of the support frame 14.

[0038] An automatic water replenishment tank inlet 302 is fixedly connected inside the water replenishment tank 301. A connecting frame 303 is fixedly connected to the top inner wall of the water replenishment tank 301. A constant liquid level automatic water replenishment device 304 is fixedly connected to the right side of the automatic water replenishment tank inlet 302.

[0039] The right side of the constant liquid level automatic water replenishment device 304 is fixedly connected to the water inlet pipe 305, and the bottom of the water replenishment tank 301 is fixedly connected to the water replenishment tank outlet 306.

[0040] The water inlet 302 of the automatic water replenishment tank is fixedly connected to the inside of the connecting frame 303, and the water inlet pipe 305 is fixedly connected to the inside of the connecting frame 303.

[0041] The implementation principle of the backwashing device for a chemical dosing pipeline in this application embodiment is as follows: Press the start button 15 to start the backwash water pump 202. The backwash water pump 202 is connected to the outlet 306 at the bottom of the water tank 301 through the inlet 203 on its left side. The water in the tank is drawn out and pressurized. The pressurized water flows through the outlet 204 of the backwash water pump to the one-way check valve 205. The one-way check valve 205 ensures that the water flows in one direction and prevents backflow. The water finally enters the pipeline of the external chemical dosing system 206, forming a high-pressure reverse water flow to flush the residual chemical and impurities on the pipe wall.

[0042] During the backwashing process, the liquid level in the water replenishment tank 301 drops, triggering the constant liquid level automatic water replenishment device 304. When the liquid level is lower than the set value, the constant liquid level automatic water replenishment device 304 injects external tap water into the water tank through the water inlet pipe 305 and the water inlet 302 of the automatic water replenishment tank. The water inlet 302 is fixedly connected to the connecting bracket 303 to ensure stable water flow. When the liquid level reaches the set upper limit, the constant liquid level device 304 stops replenishing water to maintain the water level in the tank within a reasonable range.

[0043] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
