Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to a dosing structure that can prevent clogging. Background Technology
[0002] Phosphorus is removed from wastewater by adding chemical agents that react with the metal ions in the phosphorus removal agents to form insoluble phosphate precipitates. Commonly used chemical agents include aluminum salts (such as aluminum sulfate and polyaluminum chloride), iron salts (such as ferric chloride and ferrous sulfate), and calcium salts (such as lime).
[0003] In actual use, the phosphorus removal agent is placed in a tank and connected to a discharge pipe at the bottom. A valve is installed on the discharge pipe, and the phosphorus removal agent in the tank is discharged downward through the discharge pipe under the action of gravity. However, some phosphorus removal agents are viscous and will accumulate in the discharge pipe, reducing the flow rate and even causing blockage in severe cases, thus affecting the phosphorus removal effect. Utility Model Content
[0004] The purpose of this invention is to provide a dosing structure that can prevent blockage, so as to solve the problem mentioned in the background art that the dosing pipe is easily blocked by phosphorus removal agents.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a drug delivery structure capable of preventing blockage, comprising:
[0006] Medicine storage tank, medicine dispensing pipe and medicine supply pipe;
[0007] The upper end of the dispensing pipe is connected to the lower surface of the medicine storage tank. A three-way connector is installed on the dispensing pipe. The supply pipe is connected to the dispensing pipe through the three-way connector. The upper end of the dispensing pipe is a rinsing port, and the lower end of the dispensing pipe is a dispensing port.
[0008] The drug supply pipe is equipped with a valve and a flow sensor. The valve is located downstream of the flow sensor, and the flow sensor is connected to an external PLC controller. The PLC controller integrates an alarm.
[0009] Preferably, it also includes a supporting base plate and side supports. The supporting base plate has side supports on both sides of its upper surface, and the side supports on both sides are supported on the opposite side walls of the medicine storage tank.
[0010] Preferably, the PLC controller is installed on the outer wall of the medicine storage tank.
[0011] Preferably, the outer wall of the medicine storage container is provided with a transparent window, which is vertically positioned.
[0012] Preferably, a stirring rod is longitudinally inserted into the lower surface of the medicine storage tank, a bearing is provided at the connection between the stirring rod and the medicine storage tank, a bearing embedding groove is provided on the medicine storage tank to cooperate with the bearing, and a leak-proof gasket is provided at the bottom of the bearing embedding groove, and an impeller is provided at both the upper and lower ends of the stirring rod.
[0013] Preferably, the impeller located at the bottom of the stirring rod corresponds to the position of the drug outlet.
[0014] Preferably, a stabilizing support is provided on the lower surface of the medicine storage tank, and a bearing is also provided at the bottom end of the stabilizing support, which is sleeved on the outer wall of the stirring rod.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] In actual use, the phosphorus removal agent in the agent storage tank enters the agent outlet pipe through the supply pipe under the action of gravity. The diameter of the outlet pipe is larger than that of the supply pipe, so blockage is not likely to occur in the outlet pipe. Since the supply pipe is relatively short, blockage is also not likely to occur.
[0017] The flushing port is designed so that when the medicine outlet tube is blocked, a high-pressure water pipe can be connected to the flushing port to flush the inside of the medicine outlet tube. After use, the flushing port can be covered. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.
[0025] Example 1:
[0026] Please see Figure 1-4 This utility model provides a technical solution: a drug dosing structure that can prevent blockage, comprising: a drug storage tank 2, a drug outlet pipe 4, and a drug supply pipe 8;
[0027] The upper end of the dispensing pipe 4 is connected to the lower surface of the medicine storage tank 2. A T-connector 7 is installed on the dispensing pipe 4. The supply pipe 8 is connected to the dispensing pipe 4 through the T-connector 7. The upper end of the dispensing pipe 4 is a flushing port 6, and the lower end is a dispensing port 5. A valve 9 and a flow sensor 10 are installed on the supply pipe 8. The valve 9 is located downstream of the flow sensor 10, and the flow sensor 10 is externally connected to a PLC controller 11. An alarm 12 is integrated on the PLC controller 11. The system also includes a supporting base plate 1 and side supports 3. Side supports 3 are provided on both sides of the upper surface of the supporting base plate 1, and the side supports 3 on both sides are supported on the opposite side walls of the medicine storage tank 2. The PLC controller 11 is installed on the outer wall of the medicine storage tank 2.
[0028] Analysis of the above content: In use, the supporting base plate 1 is usually placed on the inlet channel of the biological treatment tank. The chemical storage tank 2 is supported on the supporting base plate 1 by the side bracket 3. The chemical storage tank 2 is pre-filled with phosphorus removal agent. When it is necessary to add phosphorus removal agent to the sewage, the valve 9 is opened. The phosphorus removal agent enters the outlet pipe 4 from the supply pipe 8 and finally exits into the sewage from the outlet 5. Based on the flow sensor 10 detecting the liquid flow in the supply pipe 8, the flow threshold is pre-stored in the PLC controller 11. When the flow sensor 10 detects that the flow is less than the pre-stored threshold, the PLC controller 11 outputs the control alarm 12 to alarm (when not in use, the flow sensor 10 can be removed or the power can be turned off to avoid the PLC controller 11 outputting the control alarm 12 to alarm).
[0029] Example 2:
[0030] Please see Figure 1-4 Based on Embodiment 1, this utility model provides a technical solution: a transparent window is provided on the outer wall of the medicine storage tank 2, and the transparent window is vertically set.
[0031] Analysis of the above content: The transparent window is set vertically, extending from the upper part of the outer wall of the medicine storage tank 2 to the lower side, which facilitates the observation of the liquid level inside the medicine storage tank 2. According to the needs of use, a scale value can be set next to the transparent window.
[0032] Example 3:
[0033] Please see Figure 1-4 The present invention provides a technical solution based on Embodiment 1: A stirring rod 13 is longitudinally inserted into the lower surface of the medicine storage tank 2, a bearing is provided at the connection between the stirring rod 13 and the medicine storage tank 2, a bearing embedding groove 16 is provided on the medicine storage tank 2 to cooperate with the bearing, and a leak-proof gasket is provided at the bottom of the bearing embedding groove 16, and an impeller 15 is provided at both the upper and lower ends of the stirring rod 13.
[0034] Analysis of the above content: When sewage flows in the inlet channel of the biological treatment tank, the sewage impacts the impeller 15 at the lower end of the stirring rod 13, causing the impeller 15 to rotate. Based on the lower impeller 15 driving the stirring rod 13 and the upper impeller 15 to rotate, the upper impeller 15 rotates in the reagent storage tank 2 to prevent the accumulation of substances such as sediment (or viscosity) in the reagent and causing blockage.
[0035] Example 4:
[0036] Please see Figure 1-4 Based on Embodiment 3, this utility model provides a technical solution: the impeller 15 located at the bottom of the stirring rod 13 corresponds to the position of the medicine outlet 5.
[0037] Analysis of the above content: Due to the position setting of the impeller 15 at the bottom of the stirring rod 13 and the outlet 5, when the impeller 15 is rotated by the impact of sewage, it can simultaneously agitate and disperse the phosphorus removal agent output from the outlet 5.
