Technical Field
[0001] This utility model relates to the field of municipal wastewater treatment technology, specifically to a municipal wastewater treatment and purification device. Background Technology
[0002] According to patent authorization announcement number CN209178153U, a municipal sewage treatment and purification device is disclosed. This utility model relates to the field of municipal sewage treatment technology. Its key technical points are: it includes a base and a water pump. A water collection tank is installed on the left side of the water pump. Inside the water collection tank, from top to bottom, a coarse filter and a first filter are installed via overlapping blocks. A purification box is installed on the right side of the water pump. Inside the purification box, from top to bottom, a filtration chamber, a sedimentation chamber, and an electrolysis chamber are installed. Inside the filtration chamber, from top to bottom, a second filter and a quartz sand layer are installed. Activated carbon is installed inside the sedimentation chamber. An ozone generator is fixedly installed on the outer left wall of the electrolysis chamber. An venting chamber is fixedly installed on the inner left wall of the electrolysis chamber. The venting chamber is connected to the ozone generator via a connecting pipe. This utility model solves the problems of ineffective removal of impurities in water due to the lack of activated carbon adsorption and ineffective removal of negatively charged particles by setting up a first filter, a coarse filter, a second filter, a quartz sand layer, activated carbon, an ozone generator, a venting chamber, a motor, and blades.
[0003] However, existing technologies have the following problems: During wastewater treatment, impurities easily accumulate on the top of the filter screen inside the purification tank. These impurities are often a mixture of suspended particles, grease, and microbial debris in the wastewater. As the treatment time progresses, they gradually condense and harden on the top of the filter screen, forming a hard and dense layer of dirt. Because the top of the filter screen is located in a relatively hidden position inside the purification tank, conventional cleaning tools cannot reach it. Even with high-pressure washing and manual wiping, it is difficult to completely remove these stubborn impurities. Over time, the accumulated impurities will clog the pores of the filter screen, significantly reducing its filtration efficiency. Wastewater that could have passed through the filter screen quickly now has to struggle to penetrate, which not only prolongs the treatment cycle but also causes some unfiltered wastewater to flow out directly, affecting the purification effect.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4A municipal wastewater treatment and purification device includes a sedimentation tank 1, a purification box 2 fixedly connected to the right side of the sedimentation tank 1, a water pump 3 fixedly connected to the top left side of the purification box 2, a telescopic water pipe 4 connected to the input end of the water pump 3, a suction head 5 connected to the other side of the telescopic water pipe 4, a circular plate 6 fixedly connected to the surface of the suction head 5, a floating airbag 7 fixedly connected to the bottom of the circular plate 6, a double-layer frame 8 inside the purification box 2, the top of the double-layer frame 8 extending to the top of the purification box 2, a filter screen 9 fixedly connected inside the double-layer frame 8, a support grid 10 fixedly connected inside the purification box 2, a quartz sand layer 11 on the top of the support grid 10, activated carbon 12 inside the bottom of the purification box 2, a sealing door 13 movably connected to the right side of the purification box 2, and a cleaning mechanism fixedly connected to the top of the double-layer frame 8.
[0022] Please see Figure 1-3 The cleaning mechanism includes a vibrating plate 141, which is fixedly connected to the top of the double-layer frame 8. Vibrating motors 142 are fixedly connected to the front and rear sides of the top of the vibrating plate 141. Springs 143 are fixedly connected to the four corners of the bottom of the vibrating plate 141. The bottom of the springs 143 is fixedly connected to the top of the purification box 2.
[0023] Furthermore, the vibration motor 142 effectively shakes off the impurities accumulated on the top of the filter screen 9, preventing them from caking and clogging. The spring 143 enhances the vibration effect and buffers the impact of vibration on the purification box 2, reducing equipment wear. This mechanism does not require manual cleaning, has a high degree of automation, and can continuously maintain the filtration efficiency of the filter screen 9, ensuring the continuity and stability of wastewater treatment.
[0024] Please see Figure 1-4 A crash ring 15 is fixedly connected to the surface of the circular plate 6, and the crash ring 15 is located inside the sedimentation tank 1.
[0025] Furthermore, by setting the anti-collision ring 15, the suction head 5 and the circular plate 6 can be prevented from directly colliding with the inner wall of the sedimentation tank 1 when they sway with the water flow in the sedimentation tank 1, thereby reducing wear on both, protecting the structural integrity of the equipment, extending its service life, and ensuring the smooth operation of the water suction process.
[0026] Please see Figure 1-2 The bottom sides of the support grid 10 are fixedly connected with reinforcing ribs 16, and the surface of the reinforcing ribs 16 is fixedly connected to the inner wall of the purification box 2.
[0027] Furthermore, by setting the reinforcing ribs 16, the structural strength and load-bearing capacity of the support grid 10 can be enhanced, making it more stable in supporting the quartz sand layer 11, preventing the support grid 10 from deforming or being damaged due to the weight of the quartz sand layer 11 or the impact of water flow, ensuring the stability of the filter structure and ensuring the smooth progress of the filtration process.
[0028] Please see Figure 1-2 A guide plate 17 is fixedly connected to the bottom of the inner wall of the purification box 2. The guide plate 17 is located at the bottom of the activated adsorption carbon 12.
[0029] Furthermore, the baffle plate 17 can accelerate the discharge of sewage, prevent sewage from stagnating at the bottom of the purification tank 2, improve sewage treatment efficiency, and reduce the pollution of the inside of the purification tank 2 by sewage residue.
[0030] Please see Figure 1-3 Both the front and rear sides of the double-layer frame 8 have sliding limit blocks 18, and the surface of the limit blocks 18 is fixedly connected to the inner wall of the purification box 2.
[0031] Furthermore, the setting of the limiting block 18 can prevent the double-layer frame 8 from shifting or shaking during vibration or removal and placement, ensuring its precise fit with the inner wall of the purification box 2, ensuring the stable filtration position of components such as the filter screen 9, and improving the filtration effect.
[0032] Please see Figure 1-3 The surface of the limiting block 18 is fixedly connected to the limiting plate 19, and the surface of the limiting plate 19 is in contact with the inner wall of the double-layer frame 8.
[0033] Furthermore, by setting the limiting plate 19, the lateral displacement of the double-layer frame 8 can be further restricted, enhancing its stability in the purification box 2, preventing the double-layer frame 8 from shaking due to factors such as vibration during equipment operation, ensuring that the filtration work is carried out in an orderly manner, and reducing frictional wear between components.
[0034] The specific implementation process of this utility model is as follows: When in use, first put the sewage into the sedimentation tank 1. After a certain period of time, the impurities in the sewage settle to the bottom. Start the water pump 3. The water pump 3, together with the telescopic water pipe 4 and the suction head 5, draws away the water at the water surface inside the sedimentation tank 1. The water first enters the top of the inner cavity of the purification tank 2. During the process of falling, the water passes through the filter screen 9, the quartz sand layer 11 and the activated adsorption carbon 12 in sequence. Finally, the water is discharged. When the filter screen 9 is used for a certain period of time, impurities will accumulate on the top of the filter screen 9.
[0035] Start the vibration motor 142, which drives the vibration plate 141 to vibrate. The vibration plate 141, in conjunction with the spring 143, further enhances its vibration efficiency. The vibration plate 141 drives the double-layer frame 8 and the filter screen 9 to vibrate. The impurities on the top of the filter screen 9 move to the right along the slope. Open the sealing door 13, and the impurities on the top of the filter screen 9 will gradually be discharged.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
