Description

Technical Field

[0001] This utility model relates to the technical field of sludge discharge devices, specifically an automatic sludge discharge device powered by an air source. Background Technology

[0002] Wastewater refers to polluted wastewater discharged from domestic and industrial processes. It contains a relatively high amount of organic matter and is relatively easy to treat. Some wastewater contains a significant amount of impurities such as sludge. Wastewater treatment is an important part of environmental protection engineering. It involves treating polluted wastewater to a level that meets discharge standards or is reusable. Conventional wastewater treatment processes include physical, chemical, and biological methods. Sludge removal is a crucial step in the wastewater treatment process, used to remove suspended solids and other solid waste from the wastewater.

[0003] Most existing sludge removal devices require sedimentation first, then draining the upper layer of water, and finally discharging the bottom sludge. This method is not only time-consuming and affects the normal operation of sewage treatment, but also labor-intensive and costly. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] In view of the problems existing in the above and / or existing automatic sludge discharge devices powered by air, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide an automatic sludge discharge device powered by an air source. During use, the device is placed in a sewage tank with the triangular bend above the water surface and the reducing pipe at the bottom of the sewage tank. When the air pump is started, a downward airflow is generated in the air pipe. The airflow enters the spherical air bubble stone and is discharged from the air outlet, generating a large number of bubbles at the bottom of the water. When the airflow enters the liquid, the sewage transfers to the gas phase due to the partial pressure difference or concentration difference. According to the principle of phase equilibrium, the liquid has an equilibrium partial pressure at a specific temperature. When carrier gas is introduced, the partial pressure of the liquid component in the gas phase approaches zero or is significantly lower than the equilibrium partial pressure of the liquid phase, forming a mass transfer driving force from the liquid phase to the gas phase. This causes the wastewater to be carried out by the airflow and enter the triangular bend through the inlet. The cylinder is activated, and the valve block rises under the action of the cylinder. The conical shape at the top of the valve block reduces the resistance of the wastewater during the rise to a certain extent, and the sealing block improves the sealing effect to a certain extent. The wastewater enters the separation pipe and is driven by the drive motor to rotate the auger, which transports the wastewater. During the transport process, the liquid is discharged from the outlet to the guide plate and then discharged from the outlet. The solid sludge is transported by the auger to the sludge outlet for discharge. This solves the problem that most existing sludge discharge devices require sedimentation first, then draining the upper layer of water, and then discharging the bottom sludge. This treatment method is not only time-consuming and affects the normal operation of wastewater treatment, but also labor-intensive and costly.

[0010] As a preferred embodiment of the automatic sludge discharge device with an air power source described in this utility model, the bottom of the separation pipe is provided with multiple water outlet holes, and a guide plate is fixedly connected to the bottom of the separation pipe, the guide plate being inclined.

[0011] As a preferred embodiment of the automatic sludge discharge device with an air power source described in this utility model, one end of the separation pipe is provided with a sludge outlet, and the bottom of the guide plate is provided with a water outlet.

[0012] As a preferred embodiment of the automatic mud discharge device with air power source described in this utility model, the bottom outer side of the variable diameter pipe is provided with multiple protrusions, the center of the protrusions is movably connected with screws, the top of the base is provided with multiple internal threaded holes, and the screws are threadedly connected to the base.

[0013] As a preferred embodiment of the automatic mud removal device with an air power source described in this utility model, counterweights are fixedly connected to the four corners of the top of the base.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the device is placed in the sewage tank with the triangular bend above the water surface and the reducing pipe at the bottom of the sewage tank. When the air pump is started, a downward airflow is generated in the air pipe. The airflow enters the spherical air bubble stone and is discharged from the air outlet, generating a large number of bubbles at the bottom of the water. When the airflow enters the liquid, the sewage transfers to the gas phase due to the partial pressure difference or concentration difference. According to the principle of phase equilibrium, the liquid has an equilibrium partial pressure at a specific temperature. When carrier gas is introduced, the partial pressure of the liquid component in the gas phase approaches zero or is significantly lower than the equilibrium partial pressure of the liquid phase, forming a mass transfer driving force from the liquid phase to the gas phase. This causes the wastewater to be carried out by the airflow and enter the triangular bend through the inlet. The cylinder is activated, and the valve block rises under the action of the cylinder. The conical shape at the top of the valve block reduces the resistance of the wastewater during the rise to a certain extent, and the sealing block improves the sealing effect to a certain extent. The wastewater enters the separation pipe and is driven by the drive motor to rotate the auger, which transports the wastewater. During the transport process, the liquid is discharged from the outlet to the guide plate and then discharged from the outlet. The solid sludge is transported by the auger to the sludge outlet for discharge. This solves the problem that most existing sludge discharge devices require sedimentation first, then draining the upper layer of water, and then discharging the bottom sludge. This treatment method is not only time-consuming and affects the normal operation of wastewater treatment, but also labor-intensive and costly. Attached Figure Description

[0021] Please see Figures 1-5 This utility model provides an automatic sludge discharge device powered by an air source, including a base 1, a reducing pipe 2 connected to the top of the base 1, a water pumping pipe 3 fixedly connected to the output end of the reducing pipe 2, a triangular bend pipe 4 fixedly connected to the output end of the water pumping pipe 3, a through hole 12 provided at the top of the triangular bend pipe 4, an air pipe 7 fixedly connected inside the through hole 12, a fixing plate 5 fixedly connected to the outer side of the top of the water pumping pipe 3, an air pump 6 fixedly connected to the top of the fixing plate 5, the output end of the air pump 6 fixedly connected to the input end of the air pipe 7, a spherical air bubble stone 22 fixedly connected to the output end of the air pipe 7, multiple air outlets 23 provided on the outer wall of the spherical air bubble stone 22, the spherical air bubble stone 22 being located inside the reducing pipe 2, multiple water inlets 18 provided at the bottom of the reducing pipe 2, a valve 8 fixedly connected to the output end of the triangular bend pipe 4, a separation pipe 9 fixedly connected to the output end of the valve 8, a separation component provided inside the separation pipe 9 for separating sludge from wastewater.

[0022] A cylinder 10 is fixedly connected to the top of the valve 8. The power output end of the cylinder 10 passes through the top of the valve 8 and is fixedly connected to a valve block 24. The top of the valve block 24 is set in a conical shape, and a sealing block 25 is fixedly connected to the bottom of the valve block 24.

[0023] The separation assembly includes a drive motor 11, one side of which is fixedly connected to one side of the separation tube 9. The power output end of the drive motor 11 passes through one end of the separation tube 9 and is fixedly connected to an auger 13.

[0024] The bottom of the separation pipe 9 is provided with multiple water outlet holes 14, and the bottom of the separation pipe 9 is fixedly connected with a guide plate 15, which is inclined.

[0025] The separator 9 has a mud outlet 17 at one end and a water outlet 16 at the bottom of the guide plate 15.

[0026] Specifically, the device is placed in the sewage tank with the triangular bend 4 above the water surface and the reducer 2 at the bottom of the sewage tank. The air pump 6 is started, and a downward airflow is generated in the air pipe 7. The airflow enters the spherical bubble stone 22 and is discharged from the air outlet 23, generating a large number of bubbles at the bottom of the water. When the airflow enters the liquid, the sewage transfers to the gas phase due to the partial pressure difference or concentration difference. According to the principle of phase equilibrium, the liquid has an equilibrium partial pressure at a specific temperature. When carrier gas is introduced, the partial pressure of the liquid component in the gas phase approaches zero or is significantly lower than the equilibrium partial pressure of the liquid phase, forming a mass transfer driving force from the liquid phase to the gas phase. This causes the wastewater to be carried out by the airflow and enter the triangular bend 4 through the inlet 18. The cylinder 10 is activated, and the valve block 24 rises under the action of the cylinder 10. The conical top of the valve block 24 reduces the resistance of the wastewater during the rise to a certain extent, and the sealing block 25 improves the sealing effect to a certain extent. The wastewater enters the separation pipe 9 and is driven by the drive motor 11 to rotate the auger 13 to transport the wastewater. During the transport process, the liquid is discharged from the outlet 14 to the guide plate 15 and then discharged from the outlet 16. The solid sludge is transported by the auger 13 to the sludge outlet 17 for discharge. This solves the problem that most existing sludge discharge devices require sedimentation first, then draining the upper layer of water, and then discharging the bottom sludge. This treatment method is not only time-consuming and affects the normal operation of wastewater treatment, but also has high labor intensity and high wastewater treatment cost. Example 2
