Description

Technical Field

[0001] The present application relates to the field of sewage treatment equipment, and more specifically, to a pre-buried integrated sewage treatment equipment. Background Art

[0002] Integrated sewage treatment equipment is generally installed below the ground surface. The ground above the equipment can be used for greening or other purposes. There is no need to build houses, heat or insulate. The pre-buried integrated sewage treatment equipment has a wide range of applications and can be used in hotels, restaurants, hospitals, residential areas, towns, stations, airports, factories, mines and scenic spots. Integrated sewage treatment equipment can treat sewage generated by life and industry, and the sewage can be recycled after treatment.

[0003] In the process of stirring and aerating sewage, the existing pre-buried sewage treatment equipment generally stirs the sewage through the centrifugal force generated by the rotation of the stirring shaft and aerates the sewage through the aeration matrix. In this process, the centrifugal force generated by the rotation of the stirring shaft will expand the sewage to the edge of the aerobic tank. Therefore, as the sewage continues to enter, part of the sewage that has just entered the aerobic tank will directly enter the lower treatment process from the overflow port under the action of its centrifugal force, resulting in incomplete aeration of the sewage. Therefore, the activated sludge in the sewage cannot obtain effective aerobic respiration, and the organic matter in the sewage cannot be decomposed into inorganic matter, thereby affecting the effect of removing pollutants. Summary of the invention

[0004] The main purpose of the present application is to provide a pre-buried integrated sewage treatment equipment, which improves the stirring effect of the sewage by causing the sewage to collide between the inner mixing drum and the outer mixing drum, and at the same time increases the S-shaped flow channel formed by the outer tube, the middle tube and the inner tube, thereby increasing the path of the sewage flow and the time for sewage filtration.

[0006] The aerobic chamber is connected to the sedimentation chamber through an overflow port at the top, and an auger mud discharger is installed at the bottom of the sedimentation chamber, and a mud guide cover is fixedly connected to the sedimentation chamber at the input end of the auger mud discharger, and a flocculant addition pipe is installed just above the mud guide cover, and a flocculant inlet pipe connected to the flocculant addition pipe and a mud discharge port connected to the output end of the auger mud discharger are respectively provided on the back of the treatment tank;

[0007] The sedimentation chamber is connected to the filter chamber through the overflow port 2 at the top, and a filter mechanism for filtering sewage is fixedly connected inside the filter chamber, and a gas transmission matrix is ​​installed directly below the filter mechanism. A self-priming pump is installed on the top of the filter mechanism, and the input end of the self-priming pump is connected to the filter mechanism through a self-priming pump input pipe, and the output end of the self-priming pump is connected to a self-priming pump output pipe extending to the inside of the equipment warehouse;

[0008] An ultraviolet sterilizer and a medicine storage tank are respectively arranged inside the equipment warehouse, and the input end of the ultraviolet sterilizer is connected to the output pipe of the self-priming pump, and the output end of the ultraviolet sterilizer extends to the outside of the treatment tank through a drain pipe, and a backwash pump is also installed inside the equipment warehouse, and the input end of the backwash pump is connected to the medicine storage tank through the backwash pump input pipe, and the output end of the backwash pump is connected to the self-priming pump input pipe through the backwash pump output pipe.

[0009] Preferably, a blower is installed at the bottom of the equipment bin, and the output end of the blower is connected to the aeration matrix and the gas transmission matrix through an air guide pipe arranged inside the pipeline connection cavity.

[0010] Preferably, the auger mud discharger is formed by a shell body docked with the mud guide cover, an auger rotatably connected to the inside of the shell body, and a motor for driving the auger to rotate.

[0011] Preferably, the stirring mechanism includes an inner stirring drum fixedly connected to the water wheel through a T-shaped connecting frame and an outer stirring drum sleeved on the outside of the inner stirring drum, wherein a driving gear is fixedly connected to the top of the inner stirring drum, and the top of the driving gear is connected to the bottom of the drainage cover through a bearing, and a gear plate is fixedly connected to the top of the outer stirring drum, and the gear plate is connected to the bottom of the drainage cover through a bearing, and a transmission gear is rotatably connected to the bottom of the drainage cover between the driving gear and the gear plate through a bearing, and the transmission gear is meshed with the driving gear and the gear plate.

[0012] Preferably, the outer side of the inner mixing drum is fixedly connected with stirring blades 2 at equal intervals along its circumferential direction, and the inner side of the outer mixing drum is fixedly connected with stirring blades 1 at equal intervals along its circumferential direction, and stirring blades 1 and 2 are parallel to each other, and through holes are opened at equal intervals along the height direction of the outer mixing drum on the outer mixing drum between two adjacent stirring blades 1.

At the same time, the first stirring blade is relatively parallel to the second stirring blade. Therefore, when the second stirring blade pushes the sewage to the outside of the inner mixing drum, the first stirring blade pushes the sewage to the inside of the outer mixing drum, thereby causing the sewage to collide between the inner mixing drum and the outer mixing drum, thereby improving the stirring effect of the sewage.

[0015] Secondly, an external power supply is used to provide power support for the self-priming pump, and the sewage inside the filter chamber is extracted by the self-priming pump. During the extraction process, the precipitated sewage is filtered through the filtering mechanism and then enters the self-priming pump input pipe. When the sewage enters the filtering mechanism, it first passes through the S-shaped flow channel formed by the outer tube, the middle tube and the inner tube, thereby increasing the flow path of the sewage and the time of sewage filtration. In the process of the sewage passing through the S-shaped flow channel, the sewage is filtered by the activated carbon filler arranged inside the S-shaped flow channel, thereby adsorbing the malodorous gases and harmful substances in the sewage, thereby improving the sewage treatment effect.

[0037] like Figure 3 and Figure 4 As shown, in this embodiment, the stirring mechanism 160 includes an inner stirring drum 168 fixedly connected to the water wheel 115 through a T-shaped connecting frame 116 and an outer stirring drum 163 sleeved on the outer side of the inner stirring drum 168, wherein the top of the inner stirring drum 168 is fixedly connected to a driving gear 166, and the top of the driving gear 166 is connected to the bottom of the drainage cover 111 through a bearing, the top of the outer stirring drum 163 is fixedly connected to a gear plate 161, and the gear plate 161 is connected to the bottom of the drainage cover 111 through a bearing, and the bottom of the drainage cover 111 between the driving gear 166 and the gear plate 161 is rotatably connected to a transmission gear 165 through a bearing, and the transmission gear 165 is meshed with the driving gear 166 and the gear plate 161, and the sewage enters the pipe from the sewage 112 is introduced into the interior of the drainage cover 111, and then drives the water wheel 115 to rotate, and synchronously drives the inner mixing drum 168 to rotate, and since the driving gear 166 and the transmission gear 165 are meshed with each other, and the transmission gear 165 and the gear plate 161 are meshed with each other, during the rotation of the inner mixing drum 168 and the driving gear 166, the gear plate 161 and the outer mixing drum 163 are driven to rotate synchronously through the transmission gear 165. At the same time, it is explained that when the driving gear 166 and the inner mixing drum 168 rotate counterclockwise, the transmission gear 165 rotates clockwise, and since the transmission gear 165 is connected to the drainage cover 111 through a bearing, when the transmission gear 165 rotates clockwise, it drives the outer mixing drum 163 and the gear plate 161 to rotate clockwise synchronously.

[0038] like Figure 5As shown, in this embodiment, the outer side of the inner mixing drum 168 is fixedly connected with stirring blades 167 at equal intervals along the circumferential direction thereof, and the inner side of the outer mixing drum 163 is fixedly connected with stirring blades 162 at equal intervals along the circumferential direction thereof, and the stirring blades 162 and 167 are parallel to each other, and through holes 164 are opened at equal intervals along the height direction of the outer mixing drum 163 on the outer mixing drum 163 between two adjacent stirring blades 162, and the rotation direction of the outer mixing drum 163 and the stirring blades 1 162 is opposite to the rotation direction of the inner mixing drum 168 and the stirring blades 2 167, and the stirring blades 1 162 and the stirring blades 2 167 are relatively parallel, so when the stirring blades 2 167 push the sewage to the outside of the inner mixing drum 168, the stirring blades 1 162 push the sewage to the inside of the outer mixing drum 163, so that the sewage collides between the inner mixing drum 168 and the outer mixing drum 163, thereby improving the stirring effect on the sewage.

[0039] like Figure 7 As shown, in this embodiment, the filtering mechanism 170 includes an upper fixed plate 171 fixed to the top of the filter chamber 130 and a lower fixed plate 174 fixed to the bottom of the filter chamber 130, wherein the bottom of the upper fixed plate 171 is fixed with an outer tube 172 and an inner tube 175 in sequence from the outside to the inside, and an intermediate tube 173 between the outer tube 172 and the inner tube 175 is fixed to the top of the lower fixed plate 174, and an S-shaped flow channel is formed between the outer tube 172, the intermediate tube 173 and the inner tube 175, and the inside of the S-shaped flow channel is filled with activated carbon filler 176, and the self-priming pump 133 is provided with power support by an external power supply, and the sewage inside the filter chamber 130 is extracted by the self-priming pump 133. During the extraction process, the precipitated sewage is filtered by the filtering mechanism 170 and then enters the self-priming pump 133. Inside the suction pump input pipe 132, when the sewage enters the filter mechanism 170, it first passes through the S-shaped flow channel formed by the outer tube 172, the middle tube 173 and the inner tube 175, thereby increasing the flow path of the sewage and increasing the time for sewage filtration. In the process of the sewage passing through the S-shaped flow channel, the sewage is filtered by the activated carbon filler 176 arranged inside the S-shaped flow channel, thereby adsorbing the malodorous gases and harmful substances in the sewage, thereby improving the treatment effect of the sewage. At the same time, the air supply matrix 131 blows air into the sewage inside the filter cavity 130. On the one hand, it further improves the aerobic respiration of the sewage during sewage filtration. On the other hand, when backwashing the inside of the filter mechanism 170, the blowing effect of the air supply matrix 131 is used to improve the backwashing effect of the inside of the filter mechanism 170.

[0040] In summary:

[0041] During the use of the treatment tank 100, sewage is introduced into the drainage cover 111 from the sewage inlet pipe 112, and then the water wheel 115 is driven to rotate, and the inner mixing drum 168 is synchronously driven to rotate. Since the driving gear 166 and the transmission gear 165 are meshed with each other, and the transmission gear 165 and the gear plate 161 are meshed with each other, during the rotation of the inner mixing drum 168 and the driving gear 166, the gear plate 161 and the outer mixing drum 163 are synchronously rotated through the transmission gear 165. At the same time, it is explained that when the driving gear 166 and the inner mixing drum 168 rotate counterclockwise, the transmission gear 165 rotates clockwise, and since the transmission gear 165 is connected to the drainage cover 111 through a bearing, when the transmission gear 165 rotates clockwise, the outer mixing drum 163 and the gear plate 161 are synchronously driven to rotate clockwise. Therefore, during the rotation of the inner mixing drum 168 and the outer mixing drum 163, the outer side of the inner mixing drum 168 The second stirring blade 167 and the stirring blade 162 inside the outer stirring drum 163 stir the sewage. During the stirring process of the sewage, the rotation direction of the outer stirring drum 163 and the stirring blade 162 is opposite to the rotation direction of the inner stirring drum 168 and the second stirring blade 167. At the same time, the stirring blade 162 is relatively parallel to the second stirring blade 167. Therefore, when the stirring blade 167 pushes the sewage to the outside of the inner stirring drum 168, the stirring blade 162 pushes the sewage to the inside of the outer stirring drum 163, so that the sewage collides between the inner stirring drum 168 and the outer stirring drum 163, thereby improving the stirring effect of the sewage. At the same time, the sewage is aerated through the aeration matrix 113 at the bottom of the aerobic chamber 110, so that the activated sludge in the aerobic chamber 110 undergoes aerobic respiration, decomposes organic matter into inorganic matter, and plays a role in removing pollutants. In this process, the sewage drives the water wheel 115 to rotate and enters the inside of the aerobic chamber 110 from the channel at the middle position of the inner stirring drum 168;

[0042] Then, the sewage after aeration overflows from the overflow port 114 to the sedimentation chamber 120 for sedimentation. During the sedimentation process, the flocculant is connected to the flocculant through the flocculant inlet pipe 125, and the flocculant is introduced into the flocculant addition pipe 121, and the flocculant is introduced into the sedimentation chamber 120 through the flocculant addition pipe 121, so that the molecules in the sewage in the sedimentation chamber 120 are aggregated, thereby accelerating the sedimentation speed and efficiency of the sewage. Then, the sludge deposited on the mud guide cover 123 is regularly discharged from the sedimentation chamber 120 through the mud discharge port 126 through the auger mud discharger 124;

[0043] Subsequently, the precipitated sewage enters the interior of the filter chamber 130 from the overflow port 122. As the sewage in the filter chamber 130 increases, the self-priming pump 133 is powered by an external power supply, and the sewage in the filter chamber 130 is extracted by the self-priming pump 133. During the extraction process, the precipitated sewage is filtered by the filter mechanism 170 and then enters the self-priming pump input pipe 132. When the sewage enters the filter mechanism 170, it first passes through the S-shaped flow channel formed by the outer pipe 172, the middle pipe 173 and the inner pipe 175, thereby increasing the path of the sewage flow. , increase the time of sewage filtration. When the sewage passes through the S-shaped flow channel, the sewage is filtered by the activated carbon filler 176 arranged inside the S-shaped flow channel, so as to adsorb the malodorous gas and harmful substances in the sewage, thereby improving the sewage treatment effect. At the same time, the air transmission matrix 131 blows air into the sewage inside the filter cavity 130, on the one hand, further improving the aerobic respiration of the sewage during sewage filtration, and on the other hand, when backwashing the inside of the filter mechanism 170, the blowing effect of the air transmission matrix 131 is used to improve the backwashing effect of the inside of the filter mechanism 170;

[0044] The filtered sewage enters the ultraviolet sterilizer 141 through the self-priming pump output pipe 135, and the ultraviolet rays generated therein are used to sterilize and disinfect the filtered sewage. The sterilized water is discharged through the drain pipe 142. When the inside of the filter mechanism 170 is backwashed, the medicine in the medicine storage tank 143 is pumped into the self-priming pump input pipe 132 through the backwash pump input pipe 145 and the backwash pump output pipe 134 by the backwash pump 146, and then enters the filter mechanism 170 from the self-priming pump input pipe 132 for backwashing.
