Description

Technical Field

[0001] This utility model relates to the field of resin production, and in particular to an organic resin washing wastewater treatment device. Background Technology

[0002] Wastewater generated during resin washing is usually acidic or alkaline and needs to be neutralized to bring its pH value between 6 and 9. Then, impurities in the wastewater are removed through coagulation, sedimentation, adsorption, and other methods.

[0003] In the traditional method of neutralizing resin washing wastewater, the wastewater is usually led to a wastewater tank, the pH value of the wastewater is tested, and then acid or alkali solution is added to neutralize the wastewater. The amount of acid or alkali solution added depends on the operator's experience, and there are cases where too much or too little is added. Operators need to repeatedly measure the pH value of the wastewater and add acid or alkali solution, which not only causes waste and consumes manpower, but also poses a safety hazard to the operators due to the harmful gases volatilized from the wastewater.

[0004] Therefore, a technical solution is needed to address the technical problems of directly neutralizing wastewater from resin washing in wastewater ponds, which involves high manpower consumption, waste of acid and alkali solutions, and threats to the health of workers. Utility Model Content

[0005] The purpose of this invention is to overcome the technical problems of directly neutralizing the wastewater from washing resin in the wastewater pond, which is labor-intensive, wasteful of acid and alkali solutions, and threatens the health of operators, and to provide an organic resin washing wastewater treatment device.

[0006] This utility model provides an organic resin washing wastewater treatment device, including a tank. The top of the tank is provided with an inlet pipe, an acid pipe and an alkali pipe. The inlet pipe is provided with a first valve, the acid pipe is provided with a second valve and the alkali pipe is provided with a third valve. The bottom of the tank is provided with a drain pipe and a fourth valve. A pH sensor and a level gauge are provided inside the tank.

[0007] This utility model discloses an organic resin washing wastewater treatment device. In use, the resin washing wastewater is discharged into a tank through an inlet pipe. A level gauge inside the tank monitors the wastewater level to determine the actual wastewater volume. Simultaneously, a pH sensor inside the tank monitors the wastewater's pH value in real time. Based on the total wastewater volume and pH value, appropriate amounts of acid or alkali are added to the tank through an acid or alkali pipe to neutralize the resin washing wastewater. This saves manpower, ensures a more accurate acid / alkali ratio to wastewater, and reduces unnecessary waste. Furthermore, the wastewater treatment process is located within the tank, preventing wastewater evaporation from threatening the health of workers.

[0008] Preferably, the system further includes a controller, wherein the first valve, the second valve, the third valve, the fourth valve, the level gauge, and the pH sensor are electrically connected to the controller.

[0009] When the level gauge detects that the waste liquid level in the tank has reached the threshold, it transmits a signal to the controller. The controller then closes the first valve. At the same time, the pH sensor detects the pH value of the waste liquid in real time and transmits the signal to the controller. Based on the total amount of waste liquid and its pH value, the controller selects to open the second or third valve and adds an appropriate amount of acid or alkali to neutralize the waste liquid in the tank, thus achieving automatic treatment of resin washing wastewater.

[0010] Preferably, the system further includes a stirring mechanism, which includes a stirring shaft disposed within the tank, a stirring paddle disposed on the side of the stirring shaft, and a motor disposed on the top of the tank to drive the stirring shaft to rotate.

[0011] The motor drives the stirring shaft to rotate, which in turn drives the stirring paddle to stir the waste liquid and acid / alkali solutions, thereby increasing the speed of the neutralization reaction in the tank and making the waste liquid react more thoroughly.

[0012] Preferably, the inner side wall of the tank is provided with a mounting plate, and the level gauge is mounted on the mounting plate.

[0013] This allows for the installation of a level gauge inside the tank, facilitating the measurement of the liquid level height within the tank.

[0014] Preferably, the top of the tank is provided with a mounting hole, and a sleeve is detachably provided in the mounting hole. One end of the sleeve extends into the tank. The probe of the pH sensor is located at one end of the sleeve extending into the tank. The transmitter of the pH sensor is located at the top of the tank. The wire of the pH sensor is located inside the sleeve.

[0015] The pH sensor probe is inserted into the tank through a sleeve, which facilitates contact between the pH sensor probe and the liquid surface, while preventing interference between the wires connecting the probe and the transmitter and the stirring mechanism inside the tank. It also makes it easier to remove the probe for maintenance and replacement.

[0016] Preferably, the outer wall of the sleeve is provided with external threads, a limiting plate is fitted on the sleeve, the sleeve is threadedly connected to the limiting plate through the external threads, and the diameter of the limiting plate is larger than the mounting hole.

[0017] The sleeve is detachably installed on the top of the tank, making it easy to remove the pH sensor probe for maintenance or replacement. At the same time, the limiting plate on the sleeve can be rotated to be located at different heights of the sleeve, so that the sleeve can be inserted into the tank to different depths, thereby enabling the pH sensor probe to measure the pH of waste liquid at different liquid levels.

[0018] Preferably, the top of the tank is provided with a limiting groove that matches the shape of the limiting plate, and the mounting hole is disposed in the limiting groove.

[0019] The limiting plate is embedded into the limiting groove for installation. The limiting groove limits the limiting plate and prevents the sleeve and the probe of the pH sensor from shaking.

[0020] Preferably, the edge of the limiting plate is provided with an elastic sealing gasket.

[0021] It can improve the sealing performance of the limit plate to the mounting hole, and reduce the evaporation of toxic and harmful gases generated by waste liquid in the tank through the mounting hole.

[0022] Preferably, the sleeve has an elastic plug at one end outside the tank, and the elastic plug has a through hole for the pH sensor wire to pass through.

[0023] By adding an elastic plug to the end of the sleeve, it can be fixed to the wires of the pH sensor and also provide a secondary seal for the sleeve, reducing the evaporation of waste liquid from the tank.

[0024] Preferably, the sleeve is a structural component made of polytetrafluoroethylene.

[0025] The sleeve made of polytetrafluoroethylene has strong corrosion resistance and can have a long service life in acidic and alkaline environments.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] This utility model provides an organic resin washing wastewater treatment device. By setting up a tank, the resin washing wastewater is treated inside the tank, which can avoid the volatilization that threatens the health of the workers.

[0028] This utility model provides an organic resin washing wastewater treatment device. The device uses a level gauge to detect the wastewater level in the tank and a pH sensor to monitor the pH value of the wastewater in real time. This facilitates accurate control of the selection and dosage of neutralizing solution, avoids waste, and saves manpower. Attached Figure Description

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, an organic resin washing wastewater treatment device includes a tank 1. The top of the tank 1 is provided with an inlet pipe 2, an acid pipe 3, and an alkali pipe 4. The inlet pipe 2 is provided with a first valve 21, the acid pipe 3 is provided with a second valve 31, and the alkali pipe 4 is provided with a third valve 41. The bottom of the tank 1 is provided with a drain pipe 5, and the drain pipe 5 is provided with a fourth valve 51. A pH sensor 6 and a level gauge 7 are provided inside the tank 1.

[0041] During use, the resin washing wastewater is discharged into the tank 1 through the inlet pipe 2. The level gauge 7 detects the wastewater level in the tank 1 to obtain the actual wastewater volume. At the same time, the pH sensor 6 inside the tank 1 detects the pH value of the wastewater in real time. Based on the total amount of wastewater and the pH value, an appropriate amount of acid or alkali is added to the tank 1 through the acid pipe 3 or the alkali pipe 4 to neutralize the resin washing wastewater, saving manpower and making the ratio of acid / alkali to wastewater more accurate, reducing unnecessary waste. In addition, the wastewater treatment process is located inside the tank 1, avoiding the volatilization of wastewater that may threaten the health of the operators.

[0042] Installation of level gauge 7: An mounting plate 10 is provided on the inner side wall of the tank body 1, and the level gauge 7 is installed on the mounting plate 10, which realizes the installation of level gauge 7 in the tank body 1, thereby facilitating the measurement of liquid level height in the tank body 1 by level gauge 7.

[0043] Installation of pH sensor 6: The top of the tank 1 is provided with a mounting hole 101, and a detachable sleeve 11 is provided in the mounting hole 101. The sleeve 11 is a polytetrafluoroethylene (PTFE) structural component. One end of the sleeve 11 extends into the tank 1. The probe 61 of the pH sensor 6 is located at the end of the sleeve 11 extending into the tank 1. The transmitter 62 of the pH sensor 6 is located at the top of the tank 1. The wire of the pH sensor 6 is located inside the sleeve 11. The probe 61 of the pH sensor 6 is extended into the tank 1 through the sleeve 11, which facilitates the contact between the probe 61 of the pH sensor 6 and the liquid surface, and at the same time avoids interference between the wire between the probe 61 and the transmitter 62 and the stirring mechanism 9 inside the tank 1. It also facilitates the removal of the probe 61 for maintenance and replacement.

[0044] Specifically, the outer wall of the sleeve 11 is provided with external threads, and a limiting plate 12 is fitted on the sleeve 11. The sleeve 11 is threadedly connected to the limiting plate 12 through the external threads. The diameter of the limiting plate 12 is larger than the mounting hole 101, which realizes the detachable installation of the sleeve 11 on the top of the tank 1, making it convenient to remove the probe 61 of the pH sensor 6 for maintenance or replacement. At the same time, by rotating the limiting plate 12 on the sleeve 11, the limiting plate 12 is positioned at different heights of the sleeve 11, so that the sleeve 11 can be inserted into the tank 1 at different depths, thereby enabling the probe 61 of the pH sensor 6 to measure the pH of waste liquid at different liquid levels.

[0045] Furthermore, the top of the tank body 1 is provided with a limiting groove 102 that is adapted to the shape of the limiting plate 12. The mounting hole 101 is set in the limiting groove 102. The limiting plate 12 is embedded into the limiting groove 102 for installation. The limiting groove 102 plays a limiting role for the limiting plate 12, preventing the sleeve 11 and the probe 61 of the pH sensor 6 from shaking. At the same time, an elastic sealing gasket 121 is provided on the edge of the limiting plate 12. The elastic sealing gasket 121 is a rubber structural component, which can improve the sealing performance of the limiting plate 12 to the mounting hole 101 and reduce the volatilization of toxic and harmful gases generated by the waste liquid in the tank body 1 through the mounting hole 101.

[0046] Furthermore, the sleeve 11 is provided with an elastic plug 13 at one end outside the tank 1. The elastic plug 13 is a rubber structural component. The elastic plug 13 is provided with a wire hole for the pH sensor 6 wire to pass through. By adding an elastic plug 13 at the end of the sleeve 11, it can be fixed to the pH sensor 6 wire and can also provide a secondary seal for the sleeve 11, reducing the evaporation of waste liquid from the tank 1.

[0048] In this embodiment, when the level gauge 7 detects that the waste liquid level in the tank 1 has reached the threshold, it transmits a signal to the controller 8. The controller 8 then controls the first valve 21 to close. At the same time, the pH sensor 6 detects the pH value of the waste liquid in real time and transmits the signal to the controller 8. The controller 8 selects to open the second valve 31 or the third valve 41 based on the total amount of waste liquid and the pH value of the waste liquid, and adds an appropriate amount of acid or alkali to neutralize the waste liquid in the tank 1, thereby realizing the automatic treatment of resin washing wastewater. Example 3
