Description

Technical Field

[0001] This utility model belongs to the field of organic chemical production technology, and in particular relates to a neutralization and precipitation device for wastewater from the production of 3,5-dibromo-o-aminobenzaldehyde. Background Technology

[0002] The neutralization reaction tank is the core unit of the neutralization and precipitation device for 3,5-dibromo-o-aminobenzaldehyde production wastewater. NaOH or hydrochloric acid is added to adjust the pH to neutral or weakly alkaline, promoting pollutant precipitation. This wastewater typically contains bromide ions, amino compounds, aldehydes, and strong acids or bases, and its pH value may fluctuate significantly. Therefore, the treatment process needs to include key steps such as pretreatment, neutralization reaction, precipitation separation, and sludge disposal. During the neutralization and precipitation process, impurities in the wastewater can be removed, reducing pollution. However, the neutralization and precipitation device for 3,5-dibromo-o-aminobenzaldehyde production wastewater still has the following drawbacks in actual use:

[0003] In the neutralization and precipitation device for wastewater from the production of 3,5-dibromo-o-aminobenzaldehyde, it is necessary to discharge the wastewater and the precipitated impurities separately. However, if the outlets for the impurities and wastewater are too close together, the precipitate is easily discharged along with the wastewater, affecting the purification effect of the wastewater.

[0004] Secondly, during the neutralization and precipitation process of 3,5-dibromo-o-aminobenzaldehyde production wastewater, the temperature of the wastewater continuously rises (neutralization is an exothermic reaction). When the temperature of the wastewater is too high, side reactions are likely to occur, affecting the wastewater treatment effect. This requires manual adjustment by staff, which is inconvenient to operate. Utility Model Content

[0005] The purpose of this invention is to provide a neutralization and precipitation device for wastewater from the production of 3,5-dibromo-o-aminobenzaldehyde. By setting up a conveying chamber, a drive motor, and an installation sleeve, this invention solves the problems that the neutralization and precipitation device for 3,5-dibromo-o-aminobenzaldehyde production wastewater is prone to causing the sediment to be discharged with the wastewater, affecting the wastewater purification effect, and lacks feedback to adjust the neutralization temperature of the wastewater.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a neutralization and precipitation device for wastewater from the production of 3,5-dibromo-o-aminobenzaldehyde. It includes a conveying chamber, a drive motor, and a mounting sleeve. The drive motor is fixed to the top of the conveying chamber, and a rotating shaft is fixed to the output end of the drive motor. An output hopper is fixedly connected to the bottom of the conveying chamber, and a stirring block is fixed to the bottom of the rotating shaft. The stirring block is placed inside the output hopper. The mounting sleeve is fixedly installed through the top of the conveying chamber on one side of the drive motor, and a temperature-sensitive switch is fixed to the bottom of the mounting sleeve. During operation, the wastewater to be neutralized and precipitated is received through the conveying chamber. The wastewater precipitated in the conveying chamber falls into the output hopper. The drive motor drives the rotating shaft to rotate, while the wastewater and the neutralized material in the conveying chamber are fully mixed and neutralized. The temperature-sensitive switch is fixed within the mounting sleeve.

[0008] Furthermore, the top of the conveying chamber outside the drive motor is fixedly connected to a feed pipe in a ring array. Each feed pipe is fixed with an electrically controlled valve on its periphery. The conveying chamber transports wastewater and materials for neutralizing wastewater into it through the feed pipe.

[0009] Furthermore, a support is fixed to the lower periphery of the conveying chamber, and an output pipe is fixedly connected to the lower periphery of the conveying chamber above the support. An electric control valve is also fixed to the periphery of the output pipe. The support on the conveying chamber is supported on the conveying chamber. The output pipe discharges the neutralized wastewater in the conveying chamber, and the electric control valve on the periphery of the output pipe controls the on / off of the conveying.

[0010] Furthermore, a transparent discharge pipe is fixedly connected to the output end of the output hopper, and an electrically controlled valve is fixed to the periphery of the transparent discharge pipe. The transparent discharge pipe on the output hopper discharges sediment, and the electrically controlled valve controls the on / off of the transparent discharge pipe.

[0011] Furthermore, the rotating shaft passes through the top of the conveying chamber, and a stirring frame is fixed around the rotating shaft in the middle of the conveying chamber. When the rotating shaft rotates, it drives the stirring frame to rotate, and when the stirring frame rotates, it mixes the wastewater and neutralizing materials in the conveying chamber evenly.

[0012] Furthermore, the top of the mounting sleeve is flush with the top of the conveying chamber, and the bottom of the mounting sleeve is closed. The thermal switch inside the mounting sleeve closes the electrically controlled valve 1 on the feed pipe of the conveying neutralizing material after the wastewater in the conveying chamber overheats, thus preventing the wastewater in the conveying chamber from overheating.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of sediment being discharged along with the wastewater in the neutralization and sedimentation device for 3,5-dibromo-o-aminobenzaldehyde production wastewater, thus affecting the wastewater purification effect, by setting up a conveying chamber and a drive motor. When it is necessary to clean the sediment in the output hopper, while keeping the drive motor running, open the second solenoid valve. By stirring with the stirring block, the fluidity of the sediment in the output hopper is maintained. Observe the discharge situation in the transparent discharge pipe until the sediment is discharged. Then close the second solenoid valve to complete the work. When it is necessary to discharge the wastewater after sedimentation in the conveying chamber, first turn off the drive motor, let the wastewater in the conveying chamber settle, and then open the first solenoid valve on the output pipe to discharge the neutralized wastewater in the conveying chamber. This allows the wastewater drainage and sediment to be discharged separately, resulting in a better wastewater purification effect.

[0015] This invention solves the problem of lacking feedback regulation of wastewater neutralization temperature by setting up a conveying chamber and an installation sleeve. When wastewater is being neutralized in the conveying chamber, the electrically controlled valve on the feed pipe of the neutralizing material is opened, and the material falls into the conveying chamber to neutralize the wastewater. The temperature of the wastewater rises. When the temperature of the wastewater is too high, the temperature is transmitted to the temperature-sensitive switch through the installation sleeve. The temperature-sensitive switch closes, shutting down the electrically controlled valve one on the feed pipe of the neutralizing material. After the temperature in the conveying chamber drops, the temperature-sensitive switch opens, opening the electrically controlled valve one on the feed pipe of the neutralizing material to prevent the wastewater in the conveying chamber from overheating. This allows the neutralization and precipitation device for dibromo-o-aminobenzaldehyde production wastewater to provide feedback regulation of the wastewater neutralization temperature.

It includes a conveying chamber 1, a drive motor 2, and a mounting sleeve 3. The drive motor 2 is fixed to the top of the conveying chamber 1. The conveying chamber 1 is used to contain the wastewater from the production of 3,5-dibromo-o-aminobenzaldehyde and to perform neutralization and precipitation of the wastewater. The drive motor 2 drives and controls the rotation of a rotating shaft 201. The output end of the drive motor 2 is fixed to the rotating shaft 201. The rotation of the rotating shaft 201 drives the stirring frame 202 and the stirring block 203 to rotate and stir the material. The bottom end of the conveying chamber 1 is fixedly connected to an output hopper. 105. The output hopper 105 collects the sediment generated in the conveying chamber 1. The bottom end of the rotating shaft 201 is fixed with a stirring block 203. The stirring block 203 is set in the output hopper 105. When the stirring block 203 rotates, it stirs the sediment in the output hopper 105. The top of the conveying chamber 1 on one side of the drive motor 2 is fixed with an installation sleeve 3. The installation sleeve 3 fixes the temperature-sensitive switch 301 in it. The temperature-sensitive switch 301 is also fixed at the bottom of the installation sleeve 3. When the wastewater from the production of 3,5-dibromo-o-aminobenzaldehyde in the conveying chamber 1 is overheated, the temperature-sensitive switch 301 shuts down the electric control valve 102 on the feed pipe 101.

[0027] Specifically, the top of the conveying chamber 1 outside the drive motor 2 is fixedly connected to the feed pipes 101 in a ring array. Each feed pipe 101 is fixed with an electric control valve 102 on its periphery. The top of the feed pipes 101 are connected to the pipelines for conveying the wastewater from the production of 3,5-dibromo-o-aminobenzaldehyde and the materials for neutralizing the wastewater. The wastewater from the production of 3,5-dibromo-o-aminobenzaldehyde and the materials for neutralizing the wastewater in the conveying chamber 1 are all input through the feed pipes 101, and the feed pipes 101 are controlled by the electric control valves 102 to control the on / off of the conveying.

[0028] Furthermore, a support 104 is fixed to the lower periphery of the conveying chamber 1, and an output pipe 103 is fixedly connected to the lower periphery of the conveying chamber 1 above the support 104. An electric control valve 102 is also fixed to the periphery of the output pipe 103. The conveying chamber 1 is supported on the ground by the support 104. The end of the output pipe 103 away from the conveying chamber 1 is connected to the equipment for receiving neutralized wastewater. The conveying on and off of the output pipe 103 is controlled by the electric control valve 102. When the electric control valve 102 on the output pipe 103 is opened, part of the neutralized and precipitated wastewater in the conveying chamber 1 is discharged.

[0029] Furthermore, a transparent discharge pipe 106 is fixedly connected to the output end of the output hopper 105, and an electric control valve 107 is fixed to the periphery of the transparent discharge pipe 106. The bottom end of the transparent discharge pipe 106 on the output hopper 105 is connected to the water that has settled in the receiving wastewater, and the electric control valve 107 controls the on / off of the conveying of the transparent discharge pipe 106.

[0030] Furthermore, the rotating shaft 201 passes through the top of the conveying chamber 1, and a stirring frame 202 is fixed around the rotating shaft 201 in the middle of the conveying chamber 1. When the rotating shaft 201 rotates, it drives the stirring frame 202 to rotate, so as to quickly and evenly mix the wastewater and neutralizing materials entering the conveying chamber 1.

[0031] The operation process of this embodiment is as follows: During operation, wastewater is transported to the conveying chamber 1 through part of the feed pipe 101 until the wastewater content in the conveying chamber 1 is higher than the height of the stirring frame 202. Then, the drive motor 2 is started, and the drive motor 2 drives the rotating shaft 201 to rotate. At the same time, the rotation of the rotating shaft 201 drives the stirring frame 202 and the stirring block 203 to rotate. Meanwhile, the neutralized material is transported to the conveying chamber 1 through other feed pipes 101. Through the rotation of the stirring frame 202, the wastewater and neutralized material in the conveying chamber 1 are stirred evenly. The resulting sediment is transported to the lower part of the conveying chamber 1 and then... When it is necessary to clean the sediment in the output hopper 105, while keeping the drive motor 2 running, open the second solenoid valve 107. By stirring with the stirring block 203, keep the sediment in the output hopper 105 fluid. Observe the discharge situation in the transparent discharge pipe 106 until the sediment is discharged. Then close the second solenoid valve 107 to complete the work. When it is necessary to discharge the wastewater after sedimentation in the conveying chamber 1, first turn off the drive motor 2. After the wastewater in the conveying chamber 1 has settled, open the first solenoid valve 102 on the output pipe 103 to discharge the neutralized wastewater in the conveying chamber 1.

Based on the specific embodiment one, the top of the mounting sleeve 3 is flush with the top of the conveying chamber 1, the bottom of the mounting sleeve 3 is closed, and the top of the mounting sleeve 3 is open for the wire harness of the temperature-sensitive switch 301 to pass through. The temperature-sensitive switch 301 controls the switch of the solenoid valve 102 on the feed pipe 101 for conveying and neutralizing materials.

[0033] The operation process of this embodiment is as follows: During operation, when the wastewater is neutralized in the conveying chamber 1, the solenoid valve on the feed pipe 101 for conveying neutralized materials is opened, and the material falls into the conveying chamber 1 to neutralize the wastewater. The temperature of the wastewater rises. When the temperature of the wastewater is too high, the temperature is transmitted to the temperature-sensitive switch 301 through the mounting sleeve 3. The temperature-sensitive switch 301 closes, closing the solenoid valve 102 on the feed pipe 101 for conveying neutralized materials. After the temperature in the conveying chamber 1 drops, the temperature-sensitive switch 301 opens, opening the solenoid valve 102 on the feed pipe 101 for conveying neutralized materials to prevent the wastewater in the conveying chamber 1 from overheating.
