Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to a municipal sewage treatment device. Background Art

[0002] Municipal buildings are increasing day by day, and the demand for environmental quality in cities is also increasing. A large amount of sewage is generated in daily municipal work. Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. As the demand for environmental quality in cities continues to increase, the need for sewage treatment is also particularly important.

[0003] When treating sewage, existing sewage treatment devices not only need to filter the sewage, but also use flocculants to adsorb and precipitate ions or relatively fine impurities in the sewage. However, when precipitating sewage, existing sewage treatment devices usually directly put the flocculants into the device, so that the contact position between the flocculants and the sewage is relatively fixed, resulting in a relatively certain flocculation effect on the sewage.

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0040] Embodiment 1

[0041] like Figure 1 - Fig.13 As shown, a municipal sewage treatment device proposed in the first embodiment of the present application includes:

[0042] The housing 1 has a main filter plate 101 installed inside, so that the inside of the housing 1 is divided into a filter chamber 102 and a sedimentation chamber 103 from top to bottom by the main filter plate 101. The main filter plate 101 is tiltedly installed in the housing 1, and the highest point of the main filter plate 101 is located at the position of the opening inside the housing 1. The housing 1 has a water outlet 104 in the sedimentation chamber 103. A shielding plate 105 for shielding the water outlet 104 is slidably installed on the housing 1. The housing 1 has an opening so that the inside is connected with the outside. When the sewage and the flocculant react, the shielding plate 105 is slid to release the shielding of the water outlet 104, so that the sewage can be discharged from the sedimentation chamber 103.

[0043] When in use, sewage is discharged from the opening of the housing 1 to the housing 1, so that the sewage can pass through the main filter plate 101, and the larger dirt in it is blocked by the main filter plate 101, so that the sewage can enter the sedimentation chamber 103, so that the dirt can stay in the filter chamber 102, and the main filter plate 101 is tilted, so that when the dirt is in the filter chamber 102, it will not cover the upper surface of the main filter plate 101, so that the main filter plate 101 can be used normally, reducing the possibility that the main filter plate 101 is blocked and causing the sewage to be unable to enter the sedimentation chamber 103, thereby increasing the practicality of the device;

[0044] The stirring member 2 is installed in the sedimentation chamber 103. The stirring member 2 includes a driving motor 201. A driving rod 205 is installed on the output shaft of the driving motor 201 through a universal joint. A stirring rod 202 is installed on the driving rod 205 through a bevel gear set 206. The stirring rod 202 is rotatably matched with the sedimentation chamber 103. The universal joint, the driving rod 205 and the bevel gear set 206 make the axis of the stirring rod 202 and the output shaft of the driving motor 201 have an angle, so that both ends of the stirring rod 202 can be exposed, which is convenient for subsequent operations.

[0045] A cavity 203 is formed on the stirring rod 202, and a feed pipe 204 connected to the cavity 203 is installed on the housing 1. One end of the stirring rod 202 passes through the housing 1 and is rotatably connected to the mouth of the feed pipe 204. A discharge port 207 is formed on the other end of the stirring rod 202. The feed pipe 204 is used to feed a flocculant, which is aluminum sulfate, ferric chloride or other sewage flocculants.

[0046] When in use, the flocculant can be added to the feed pipe 204 from the outside, so that it enters the cavity 203 and is discharged from the discharge port 207 into the sedimentation chamber 103. At this time, when the driving motor 201 drives the stirring rod 202, the movement of the flocculant in the sedimentation chamber 103 is increased by the rotation of the stirring rod 202, thereby making the flocculant and the sewage in better contact, so that the flocculant can better precipitate smaller impurities and heavy metal ions in the sewage, thereby increasing the flocculation effect of the device;

[0047] The extension shell 3 is installed on the side wall of the outer shell 1. The extension shell 3 is located at one end of the lowest point of the main filter plate 101. A communication port 3010 communicating with the extension shell 3 is provided on the outer shell 1. A secondary filter plate 301 is installed on the extension shell 3. The extension shell 3 is located below the secondary filter plate 301 and is provided with a through port 302 communicating with the sedimentation chamber 103. The extension shell 3 is provided on the side wall of the outer shell 1 to extend the volume of the filter chamber 102. When in use, part of the dirt moves into the extension shell 3 along with the sewage along the guide of the inclined surface of the main filter plate 101, and is filtered through the secondary filter plate 301. The sewage can enter the sedimentation chamber 103 through the communication port 3010. The volume of the filter chamber 102 is increased by the extension shell 3, and the capacity of the device to hold dirt is increased.

[0048] When the device is in use, multiple devices cooperate to treat sewage at the same time. When in use, the same batch of sewage is discharged into different devices for simultaneous treatment, so that the sewage can be treated in batches. After entering the sedimentation chamber 103, the Shudie sewage has enough time to react with the flocculant. After the reaction is completed, it is discharged through the water outlet 104;

[0049] Compared with the prior art, when sewage is treated, the sewage is discharged into the device through the inlet of the outer shell 1, the sewage is preliminarily filtered through the main filter plate 101, and part of the sewage enters the extension shell 3 through the connecting port 3010. The capacity of the device is increased by the extension shell 3. When the sewage is precipitated, flocculant is added from the feed pipe 204 into the cavity 203 of the stirring rod 202. After the flocculant enters the sedimentation chamber 103 through the discharge port 207, the activity of the flocculant in the sedimentation chamber 103 is increased through the stirring of the stirring rod 202, thereby increasing the contact between the flocculant and the sewage, and thereby increasing the sedimentation effect of the flocculant on the sewage.

[0050] Embodiment 2

[0051] like Fig. 9 As shown, the second embodiment is based on the first embodiment to further disclose the outer shell 1, the stirring rod 202, the sedimentation chamber 103 and the extension shell 3. In the second embodiment, the position of the stirring rod 202 close to the feed pipe 204 is higher than the end away from the feed pipe 204. A side hole 208 connected to the cavity 203 is provided on the side wall of the stirring rod 202. When in use, the stirring rod 202 is tilted in the sedimentation chamber 103 so that the added flocculant can move to the discharge port 207 by gravity, and the side hole 208 is provided on the side wall of the stirring rod 202 along the axial direction of the stirring rod 202. When in use, when the stirring rod 202 rotates, the flocculant in the cavity 203 can be thrown out by centrifugal force, so that the flocculant can be better diffused into the sedimentation chamber 103, thereby increasing the practicality of the device.

[0052] like Figure X As shown, in the second embodiment, a containing shell 4 is installed in the sedimentation chamber 103, and the drive motor 201 is installed in the containing shell 4. The containing shell 4 is used to protect the drive motor 201. The containing shell 4 is provided with an opening for the output shaft of the drive motor 201 to pass through. A sealed bearing is installed in the opening to reduce the contact between the sewage and the drive motor 201. The drive motor 201 is protected by the containing shell 4, and the possibility of damage to the drive motor 201 is reduced.

[0053] The main filter plate 101 is hinged in the shell 1, and a pad 5 for supporting the free end of the main filter plate 101 is installed in the shell 1. The pad 5 is located at the bottom of the main filter plate 101, so that the main filter plate 101 can move in the shell 1, and a connecting spring 6 is installed between the main filter plate 101 and the shell 1. The accommodating shell 4 is in contact with the main filter plate 101, and the connecting spring 6 is connected to the main filter plate 101, and the connecting spring 6 is located on a side away from the hinge point of the main filter plate 101, so that when the main filter plate 101 shakes, the connecting spring 6 repeatedly elastically deforms so that the main filter plate 101 can be in a shaking state for a long time, and the main filter plate 101 is supported by the pad 5, which reduces the possibility of the main filter plate 101 moving too much and causing a gap between it and the inside of the shell 1, thereby causing larger dirt to enter the sedimentation chamber 103, thereby increasing the feasibility of the device;

[0054] When in use, after the driving motor 201 is started, it will generate vibration, and the vibration will be transmitted to the containing shell 4 and then to the main filter plate 101, so that the main filter plate 101 will vibrate, and the elastic deformation of the connecting spring 6 will make the main filter plate 101 shake to a greater extent, so that the dirt on the main filter plate 101 can move along the inclined surface of the main filter plate 101 into the extension shell 3, and in the process of the vibration of the main filter plate 101, the elastic deformation of the connecting spring 6 will reduce the relative speed between the main filter plate 101 and the backing plate 5, thereby reducing the possibility of damage to the two during vibration, and increasing the practicality of the device;

[0055] During the process, the side effect of vibration generated by the driving motor 201 provides vibration for the main filter plate 101, so that it can perform a sieving separation operation to better separate dirt from sewage, and enable the dirt on it to better enter the extension shell 3, thereby increasing the practicality of the device.

[0056] like Figure 6 and Fig.11As shown, in the second embodiment, a toggle member 7 is installed in the sedimentation chamber 103, and the toggle member 7 includes a driving roller 701 and a transmission roller 702 rotatably installed in the sedimentation chamber 103, a transmission belt 703 is installed between the driving roller 701 and the transmission roller 702, and a toggle plate 704 is installed on the transmission belt 703. The driving roller 701, the transmission roller 702 and the transmission belt 703 form a structure of a conveyor belt, and the toggle plate 704 is located on the transmission belt 703, so that when the driving roller 701 and the transmission roller 702 rotate, the toggle plate 704 is driven to move in the sedimentation chamber 103, and the flocculants located at the bottom of the inner wall of the sedimentation chamber 103 are scraped by the toggle plate 704;

[0057] A guide tube 705 is installed in the sedimentation chamber 103, and a rotating paddle 706 is rotatably installed in the guide tube 705. The guide tube 705 is located at the bottom of the main filter plate 101. When the sewage is discharged into the housing 1 and filtered by the main filter plate 101, part of the sewage will enter the guide tube 705. The guide tube 705 guides the sewage of this part, so that the sewage entering the guide tube 705 can push the rotating paddle 706 in a tangential direction, so that it can rotate in the guide tube 705. Through the guidance of the guide tube 705, the influence of the sewage moved by the stirring rod 202 on the movement of this part of the sewage and the rotating paddle 706 is reduced;

[0058] An active rod 707 is eccentrically mounted on the rotating shaft of the paddle 706. There are multiple active rods 707, which are arranged in a circular array on the rotating shaft of the paddle 706 along the axis direction of the paddle 706. There are multiple L-shaped rods 708 arranged in a circular array around the axis of the driving roller 701. The active rod 707 is used to contact the L-shaped rod 708, so that when the paddle 706 rotates, the driving roller 701 is driven to rotate. When the paddle 706 rotates, the active rod 707 is driven to make a circular motion around the axis direction of the paddle 706, so that the active rod 707 pushes the L-shaped rod 708, so that the driving roller 701 rotates. When the active rod 707 rotates to separate from the L-shaped rod 708, the next active rod 707 contacts the next L-shaped rod 708 again, so that when the paddle 706 rotates, the driving roller 701 can be driven to rotate.

[0059] A concave cavity 709 for accommodating precipitated impurities is provided in the sedimentation chamber 103. The highest point of the concave cavity 709 is lower than the lowest point of the water outlet 104. When the driving roller 701 rotates, the paddle plate 704 is driven to move from a side away from the concave cavity 709 to a side close to the concave cavity 709. The concave cavity 709 is used to accommodate floccules, so that the floccules can be more concentrated in the sedimentation chamber 103.

[0060] When the device is in use, when sewage enters the sedimentation chamber 103, part of the sewage enters the guide tube 705, thereby causing the paddle 706 to rotate, and then through the cooperation between the active rod 707 and the L-shaped rod 708, the driving roller 701 rotates, which in turn causes the transmission belt 703 and the transmission roller 702 to rotate, driving the paddle plate 704 to move in the sedimentation chamber 103, and then the flocculants in the sedimentation chamber 103 are moved to the concave cavity 709 by the paddle plate 704, so that when the sewage is discharged, the flocculants can be relatively concentrated in the sedimentation chamber 103, reducing the possibility of the flocculants being discharged together with the treated sewage, thereby increasing the practicality of the device.

[0061] like Fig.11 As shown, in the second embodiment, a resistance plate 8 is slidably mounted at the opening of the housing 1 through a return spring 801, and a slanted block 802 is mounted on the side of the resistance plate 8 facing the opening of the housing 1. The slanted block 802 and the resistance plate 8 reduce the opening of the housing 1, so that when sewage enters the housing 1, the sewage pushes the resistance plate 8 through the slanted block 802, causing it to slide in a direction away from the opening of the housing 1;

[0062] A spring telescopic rod 803 is hinged on the inclined block 802, and a push rod 804 is slidably installed in the shell 1. The free end of the spring telescopic rod 803 is hinged to the push rod 804. The push rod 804 is located on one side of the highest point of the main filter plate 101. The push rod 804 is J-shaped, and one end of the arc is facing the opening of the shell 1. When it slides toward the extension shell 3, it scrapes the dirt on the main filter plate 101 through its concave surface, so that it can drive more dirt to move toward the extension shell 3. When the push rod 804 is reset, the dirt is guided by its arc-shaped outer arc surface, so that it contacts it more smoothly, reducing the possibility of obstruction to its reset by the dirt, and increasing the feasibility of the device.

[0063] When the contact plate 8 slides in the direction away from the opening of the outer shell 1, the spring telescopic rod 803 pulls the push rod 804 to slide away from the opening of the outer shell 1, thereby scraping the dirt on the main filter plate 101, providing an initial force for the sliding of the dirt, so that the dirt can better fall through the inclined surface of the main filter plate 101, further reducing the possibility of the dirt clogging the main filter plate 101, increasing the practicality of the device; when the batch of sewage is added, the reset spring 801 resets and pushes the contact plate 8 to reset, thereby causing the contact plate 8 and the spring telescopic rod 803 to drive the push rod 804 to reset, facilitating the next scraping, thereby increasing the practicality of the device.

[0064] like Figure 3 , Figure 5 , Fig.10 , Fig.11 and Fig.12As shown, in the second embodiment, the auxiliary filter plate 301 is slidably mounted on the extension shell 3 through the compression spring 303. Figure 1 From the main perspective, the auxiliary filter plate 301 is slidably installed on the extension shell 3 along the vertical direction;

[0065] A vertical plate 304 is slidably mounted on one side of the extension shell 3. The vertical plate 304 is used to block or remove the blockage of one side of the extension shell 3. The edge of the extension shell 3 and the vertical plate 304 enclose the auxiliary filter plate 301, so that the extension shell 3 can accommodate sewage and dirt.

[0066] A guide rod 305 is installed on the auxiliary filter plate 301, and a guide cylinder 306 for accommodating the guide rod 305 is installed in the extension shell 3. When in use, when dirt accumulates on the auxiliary filter plate 301, the auxiliary filter plate 301 slides downward. During the sliding process, the inner wall of the guide cylinder 306 restricts the side wall of the guide rod 305, so that the auxiliary filter plate 301 can only slide in a straight line direction, thereby increasing its stability during sliding.

[0067] An extension tube 307 is installed on the free end of the guide cylinder 306, and the extension tube 307 is connected to the guide cylinder 306. A sliding rod 308 is slidably installed in the extension tube 307, and the sliding rod 308 is connected to the vertical plate 304. The extension shell 3 is installed with an inclined plate 309 on the side where the vertical plate 304 is installed. When the auxiliary filter plate 301 slides downward, the air in the guide cylinder 306 is squeezed by the guide rod 305, so that the air pushes the sliding rod 308, so that the sliding rod 308 pushes the vertical plate 304 to move upward, causing it to release the shielding of the side wall of the extension shell 3, so that the dirt can be separated from the extension shell 3 through this side of the extension shell 3;

[0068] Since the device processes sewage in batches, when the same batch of sewage is processed, the dirt gradually moves to the auxiliary filter plate 301, and the sewage and the dirt are separated. As the weight on the auxiliary filter plate 301 gradually increases, the auxiliary filter plate 301 gradually moves downward, so that the guide rod 305 squeezes the air in the guide cylinder 306, and the air pushes the sliding rod 308, so that the vertical plate 304 releases the obstruction of the edge of the extension shell 3, so that an opening connected to the outside appears on the side wall of the extension shell 3, so that the dirt can be separated from the device through the opening under the guidance of the inclined plate 309, thereby increasing the practicality of the device.

[0069] Embodiment 3

[0070] like Figure 1 - Fig.13As shown in the figure, Embodiment 3 further discloses the present application on the basis of Embodiment 2. In Embodiment 3, an inclined surface is provided on the secondary filter plate 301, and the inclined surface faces the vertical plate 304, so that the dirt located on the secondary filter plate 301 can accumulate in the direction of the vertical plate 304, enabling the dirt to be better separated from the device subsequently;

[0071] A pulling spring 9 is slidably installed in the extension shell 3, and a block is installed on the pulling spring 9. Taking Figure 1 the main perspective, the block is slidably connected to the inside of the extension shell 3 in the vertical direction, so that when the secondary filter plate 301 slides, the pulling spring 9 can fall together by gravity;

[0072] A lower push plate 10 is installed at the free end of the pulling spring 9. The lower push plate 10 is located on the highest side of the secondary filter plate 301. A contact block 11 is installed in the extension shell 3. A force-receiving inclined surface is provided on one side of the lower push plate 10, and a force-applying inclined surface parallel to the force-receiving inclined surface is provided on the contact block 11. A notch 12 for the contact block 11 to pass through is provided on the secondary filter plate 301;

[0073] When the secondary filter plate 301 moves downward, the lower push plate 10 also slides downward. When the contact block 11 passes through the notch 12, it contacts the lower push plate 10. Through the guidance of the force-applying inclined surface and the force-receiving inclined surface, the lower push plate 10 is pushed in the direction close to the vertical plate 304, providing a downward sliding force for the dirt. Furthermore, the lower push plate 10 can push the dirt to slide in the direction of the vertical plate 304. When the dirt on the secondary filter plate 301 is heavier, it can open the vertical plate 304 by changing the gravity and also push the dirt through the lower push plate 10, enabling the dirt to be better separated from the device, thereby increasing the practicality of the device.

[0074] In Embodiment 3, a lower plate 13 for shielding or unshielding the concave cavity 709 is slidably installed on the outer shell 1. The bottom of the outer shell 1 is in a U shape, so that the lower plate 13 is located outside. A ring plate 14 is installed on one side of the lower plate 13. The lower plate 13 forms the bottom of the concave cavity 709. After treating and discharging the sewage of this batch, the ring plate 14 is pulled by a rod with a hook, and then the lower plate 13 is pulled to slide, so that the concave cavity 709 is exposed, facilitating the discharge of the flocculants from the device. During the sliding process of the lower plate 13, the flocculants on it are scraped by the inner wall of the concave cavity 709, enabling the flocculants located on the lower plate 13 to be better separated from the lower plate 13 and discharged, enabling the device to discharge the flocculants and facilitating the device to treat the next batch of sewage.

[0075] In Embodiment 3, a lifting rod 15 is hinged on the outer shell 1. One end of the lifting rod 15 is used to contact the shielding plate 105, and the lifting rod 15 forms a lever structure;

[0076] A bearing plate 17 is slidably mounted on the lower plate 13 through a lower spring 16, an outer rod 18 penetrating the lower plate 13 is mounted on the bearing plate 17, a pressing plate 19 is mounted on the outer rod 18, a through slot 20 is provided on the outer shell 1, a pressure rod 21 penetrating the through slot 20 is mounted on the lifting rod 15, and the bearing plate 17 is used to carry floccules. After the treatment of the batch of sewage is completed, the floccules are moved into the concave cavity 709 by the shifting member 7. When the floccules in the concave cavity 709 accumulate too much, the weight on the bearing plate 17 increases, causing the bearing plate 17 and the outer rod 18 to slide downward, and then the pressure rod 21 is pressed by the pressing plate 19 on the outer rod 18, causing the lifting rod 15 to rotate, thereby sliding the shielding plate 105 upward to release the shielding of the water outlet 104, so that when the floccules are heavy, the sewage can be discharged, thereby reducing the steps of manual operation and increasing the practicality of the device.

[0077] When in use, the through groove 20 restricts the pressure rod 21, so that when the lifting rod 15 is in the position when the device is in normal use, it is also in an inclined state and is located below the pressing plate 19, so that when the pressing plate 19 slides downward, the pressure rod 21 can be pressed smoothly, which increases the feasibility of the device;

[0078] When the floccules need to be cleaned, after the sewage is discharged, the lifting rod 15 is rotated to drive the pressure rod 21 to move to a position where it does not block the outer rod 18, and then the lower plate 13 is slid so that the device can smoothly clean the floccules.

[0079] In embodiment three, a counterweight 22 is installed at the end of the compression rod 21 away from the baffle plate 105. The counterweight 22 enables the lifting rod 15 to tilt toward the side close to the compression rod 21, ensuring that the position of the compression rod 21 can be lower than the bottom of the pressure plate 19, further increasing the feasibility of the device.

[0080] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
