Description

Technical Field

[0001] This utility model relates to the technical field of water quality monitoring equipment, and more particularly to a depressurization flow tank for pigment production. Background Technology

[0002] With economic development and improved living standards, environmental and water pollution problems have become increasingly severe. To accurately analyze the degree of water pollution, parameters such as COD, ammonia nitrogen, color, turbidity, dissolved oxygen, conductivity, temperature, and pH need to be measured. Currently, most online water quality monitoring instruments on the market connect a flow cell to the input pipe of the liquid to be measured and the output pipe of the liquid already measured, and then install it inside the instrument's housing. The light source emitting device and receiving device are located on both sides of the flow cell and fixed inside the housing. Commonly used flow cells often employ a sealed structure, containing electrodes for measuring various parameters. During the electrode measurement process, excessive water pressure often causes the glass diaphragm on the electrode to rupture, leading to inaccurate or unmeasurable measurement results. Utility Model Content

[0003] The purpose of this invention is to provide a depressurized flow cell for pigment production, which not only solves the problem of inaccurate or unmeasurable measurement results caused by the glass membrane on the electrode breaking due to excessive water pressure during the electrode measurement of water quality, but also optimizes the electrode installation method to improve its stability and reliability.

[0004] The technical solution of this utility model is: a pressure-reducing flow tank for pigment production, wherein the pressure-reducing flow tank is box-shaped and includes a shell, a top cover, a water inlet, a water outlet, an electrode, a threaded mounting hole, a sealing gasket, a fixing plate, a fixing hole, and a pressure-reducing valve. The housing is provided with a water inlet and a water outlet. A pressure reducing valve is provided at the water inlet. The top cover is provided with a threaded mounting hole adapted to the electrode. The outer wall of the electrode is provided with an external thread. The electrode is screwed into the threaded mounting hole. The sealing gasket is provided on the contact surface between the electrode and the top cover. The two ends of the fixing plate are fixedly installed on the inner wall of the housing. The fixing plate is provided with fixing holes. The electrode is inserted into the fixing holes.

[0005] Preferably, the water inlet is located at the lower part of the housing, and the drain outlet is located at the upper part of the housing.

[0006] Preferably, the number of fixing holes is equal to the number of electrodes.

[0007] The beneficial effects of this utility model are: (1) When installing the electrode, the electrode is directly screwed into the threaded mounting hole to achieve a stable connection between the electrode and the flow cell, reducing intermediate parts, reducing installation complexity, and enhancing the stability of electrode installation. (2) After the electrode is screwed into the threaded mounting hole, a sealing gasket is set on the contact surface between the electrode and the top cover. When the electrode is tightened, the sealing gasket is squeezed and deformed, tightly filling the tiny gap between the electrode and the threaded mounting hole, effectively preventing medium leakage, and ensuring that the water pressure in the flow pool is consistent with the atmospheric pressure, avoiding damage to the electrode due to excessive water pressure. (3) To further define the position of the electrode, positioning marks can be set at the corresponding positions of the electrode and the top cover to ensure the consistency of the position each time the electrode is installed and improve the measurement accuracy; (4) A fixing plate with fixing holes is provided in the housing. The electrode is inserted into the fixing holes to prevent the electrode from shaking when the water being tested flows into the flow pool, which would affect the measurement accuracy.

[0009] In the diagram, 1 is the housing, 2 is the top cover, 3 is the water inlet, 4 is the drain outlet, 5 is the electrode, 6 is the threaded mounting hole, 7 is the sealing gasket, 8 is the fixing plate, 9 is the fixing hole, and 10 is the pressure reducing valve. Detailed Implementation

[0010] A pressure-reducing flow cell for pigment production, the pressure-reducing flow cell is box-shaped and includes a shell 1, a top cover 2, a water inlet 3, a water outlet 4, an electrode 5, a threaded mounting hole 6, a sealing gasket 7, a fixing plate 8, a fixing hole 9, and a pressure-reducing valve 10. The housing 1 is provided with a water inlet 3 and a drain outlet 4. A pressure reducing valve 10 is provided at the water inlet 3. The top cover 2 is provided with a threaded mounting hole 6 that is compatible with the electrode 5. The outer wall of the electrode 5 is provided with external threads. The electrode 5 is screwed into the threaded mounting hole 6. The sealing gasket 7 is provided on the contact surface between the electrode 5 and the top cover 2. The fixing plate 8 is fixedly installed on the inner wall of the housing 1 at both ends. The fixing plate 8 is provided with fixing holes 9. The electrode 5 is inserted into the fixing holes 9.

[0011] The water inlet 3 is located at the lower part of the housing 1, and the drain outlet 4 is located at the upper part of the housing 1.

[0012] The number of fixing holes 9 is equal to the number of electrodes 5.

[0013] To further define the position of electrode 5, positioning marks can be set at corresponding positions on electrode 5 and top cover 2 to ensure consistency in position each time electrode 5 is installed, thereby improving measurement accuracy. The working principle of this utility model is as follows: When in use, the pressure reducing valve 10 is connected to the water inlet pipe. After the water flow is reduced by the pressure reducing valve 10, it enters the flow pool from the water inlet 3, which reduces the risk of damage to the electrode 5 due to excessive water pressure. Because there is a sealing gasket 7 between electrode 5 and threaded mounting hole 6, the electrode 5 is not damaged due to excessive water pressure. When electrode 5 is tightened, the sealing gasket 7 is squeezed and deformed, tightly filling the tiny gap between electrode 5 and threaded mounting hole 6, effectively preventing medium leakage, and ensuring that the water pressure in the flow pool is consistent with the atmospheric pressure, thus preventing the electrode 5 from being damaged due to excessive water pressure. Electrode 5 is tightly connected to top cover 2 via threads. At the same time, electrode 5 is inserted into fixing hole 9 of fixing plate 8 to prevent electrode 5 from shaking when the water being tested flows into the flow tank, which would affect the measurement accuracy and ensure the stability of electrode 5 during the measurement process. The measured water flows out from drain 4.
