Description

Technical Field

[0001] The utility model relates to the technical field of ventilation for wastewater treatment, in particular to ventilation equipment for wastewater treatment. Background Art

[0002] Wastewater treatment is to treat wastewater using physical, chemical and biological methods to purify wastewater, reduce pollution, and even recycle and reuse wastewater to make full use of water resources. The wastewater produced by some factories will be mixed with some gases. Therefore, when treating and discharging wastewater, it is necessary to ventilate the gas inside the wastewater treatment box;

[0003] Prior art CN202022586776.X is a ventilation device that is easy to install. The motor is first installed on a support frame outside the casing, and then the support frame is slid into the chamber. Finally, the support frame is connected to the mounting tube using a positioning assembly to complete the installation. The motor installation process is carried out outside the casing, which reduces the restrictions of the internal space on the motor installation, making the motor installation more convenient. The mounting tube is fixed with multiple connecting plates, which on the one hand makes the connection between the mounting tube and the casing more secure, and on the other hand makes the circumferential force of the mounting tube uniform, further dispersing the force of the motor on the mounting tube, thereby improving the stability of the connection between the support frame and the mounting tube. When the casing vibrates, the sliding seat moves downward. At this time, the spring provides an upward elastic force to the extrusion plate, thereby causing the sliding seat to move upward, thereby playing a shock absorbing role.

[0004] However, when the ventilation equipment is used for some gas exhaust ventilation, when the gas contains impurities that are harmful to the environment, direct discharge will affect the environment; therefore, it does not meet the existing needs. In this regard, we have proposed a ventilation equipment for wastewater treatment. Utility Model Content

[0005] The utility model aims to provide a ventilation device for wastewater treatment, so as to solve the problem that when the ventilation device proposed in the above background technology is used for some gas exhaust ventilation, when the gas contains impurities harmful to the environment, direct discharge will affect the environment.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a ventilation device for wastewater treatment, comprising a wastewater treatment box and a ventilation pipe, a water inlet is provided on one side of the wastewater treatment box, a wastewater filter plate is provided on the side of the wastewater treatment box close to the water inlet, a ventilation pipe is connected through the wastewater filter plate on the side away from the water inlet and located at the upper end of the wastewater treatment box, an exhaust fan is fixedly connected to the inside of the ventilation pipe, a treatment frame is connected through the top of the ventilation pipe, a docking groove is provided at the upper end of the ventilation pipe, and a docking block engaged with the docking groove is fixedly connected to the bottom end of the treatment frame, an activated carbon plate is fixedly connected to the side of the treatment frame close to the exhaust fan, and a filter screen is fixedly connected to the side of the activated carbon plate away from the exhaust fan and located at the inside of the treatment frame.

[0007] Preferably, support blocks are fixedly connected to both sides of the outer surface of the ventilation pipe, and connecting plates are fixedly connected to the upper ends of the support blocks on both sides, and the connecting plates are arranged in an inverted L shape. A limiting groove is opened on one side of the connecting plate, and a movable plate is slidably connected inside the limiting groove.

[0008] Preferably, the upper end of the movable plate is fixedly connected with a connecting rod extending through and to the upper end of the connecting plate, a spring is fixedly connected between the upper end of the movable plate and the top end of the connecting plate, and the spring is wound around the outer surface of the connecting rod.

[0009] Preferably, one end of the connecting rod passing through the connecting plate is fixedly connected to a transverse plate, and the bottom end of one side of the transverse plate is fixedly connected to a limiting rod.

[0010] Preferably, both sides of the outer surface of the processing frame are fixedly connected with fixing blocks, and the upper ends of the fixing blocks on both sides are provided with slots matching the limiting rods, and the limiting rods are plugged into the slots.

[0011] Preferably, a sealing gasket is fixedly connected to the bottom end of the docking groove, and the bottom end of the docking block is in close contact with the sealing gasket.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model sends wastewater into the wastewater treatment box from the water inlet, and the wastewater filtered by the wastewater filter plate flows out to one side of the water outlet. At this time, the exhaust fan is started to pass the gas inside the wastewater treatment box through the ventilation pipe and then enter the inside of the treatment frame. The gas passes through the activated carbon plate inside the treatment frame, which can adsorb harmful impurities inside the gas and finally discharge it from the inside of the wastewater treatment box through the filter net, thereby preventing the harmful gas mixed in the wastewater from being directly discharged to pollute the environment;

[0014] 2. The utility model pulls the horizontal plates on both sides so that the horizontal plates drive the connecting rod and the movable plate upward and squeezes the spring to compress, so that the limit rod is disengaged from the card connection with the slot. Then the processing frame can be removed from the upper end of the ventilation pipe and replaced with a new processing frame. The docking block at the bottom of the new processing frame is plugged into the docking slot. The setting of the sealing gasket can prevent the gas from being discharged directly without being filtered. Then, the pull on the horizontal plate is released to release the elastic force of the spring and push the limit rod to move toward the inside of the slot for insertion, so that the processing frame is fixed to the upper end of the ventilation pipe, which is convenient for disassembly and installation.

[0022] By starting the exhaust fan 5, the gas inside the wastewater treatment box 1 passes through the ventilation pipe 3 and then enters the interior of the treatment frame 4. The gas passes through the activated carbon plate 6 inside the treatment frame 4, which can adsorb harmful impurities in the gas and finally discharge it from the interior of the wastewater treatment box 1 through the filter screen 7, thereby preventing harmful gases mixed in the wastewater from being directly discharged to pollute the environment.

[0023] Support blocks 8 are fixedly connected to both sides of the outer surface of the ventilation pipe 3, and connecting plates 9 are fixedly connected to the upper ends of the support blocks 8 on both sides, and the connecting plates 9 are set in an inverted L shape. A limiting groove 901 is provided on one side of the connecting plate 9, and a movable plate 10 is slidably connected inside the limiting groove 901. The upper end of the movable plate 10 is fixedly connected to a connecting rod 11 that extends through the upper end of the connecting plate 9. A spring 12 is fixedly connected between the upper end of the movable plate 10 and the top end of the connecting plate 9, and the spring 12 is wound around the outer surface of the connecting rod 11. One end of the connecting rod 11 passes through the connecting plate 9 and is fixedly connected to a cross plate 13. The bottom end of one side of the cross plate 13 is fixedly connected to a limiting rod 14. Fixed blocks 15 are fixedly connected to both sides of the outer surface of the processing frame 4, and slots 1501 matching the limiting rod 14 are provided on the upper ends of the fixed blocks 15 on both sides, and the limiting rod 14 is plugged into the slots 1501.

[0024] By pulling the horizontal plates 13 on both sides, the horizontal plates 13 drive the connecting rod 11 and the movable plate 10 upward, and squeeze the spring 12 to compress, so that the limiting rod 14 is disengaged from the slot 1501, and then the processing frame 4 can be removed from the upper end of the ventilation pipe 3 and replaced with a new processing frame 4.

The gas passes through the activated carbon plate 6 inside the treatment frame 4, which can adsorb harmful impurities in the gas and finally discharge it from the inside of the wastewater treatment box 1 through the filter screen 7, thereby preventing harmful gases mixed in the wastewater from being directly discharged to pollute the environment; when the treatment frame 4 is used for a long time, the adsorption effect of the activated carbon plate 6 will be weakened. By pulling the horizontal plates 13 on both sides, the horizontal plates 13 drive the connecting rods 11 and the movable plates 10 upward, and squeeze the spring 12 to compress, so that the limiting rod 14 is disengaged from the slot 1501. Then the processing frame 4 can be removed from the upper end of the ventilation pipe 3, and replaced with a new processing frame 4. The docking block 401 at the bottom of the new processing frame 4 is plugged into the docking groove 301. The setting of the sealing gasket can prevent the gas from being discharged directly without being filtered. Then, the pull on the horizontal plate 13 is released, so that the spring 12 releases the elastic force and pushes the limiting rod 14 to move toward the inside of the slot 1501 for plugging, thereby fixing the processing frame 4 to the upper end of the ventilation pipe 3.
