Description

Technical Field

[0001] The present application relates to the field of wastewater treatment, and in particular to a wastewater treatment machine that avoids blockage. Background Art

[0002] A thermal power plant refers to a thermal power plant that uses steam extraction or exhaust from steam turbines to provide heat to users while generating electricity. Its main working principle is to use the hot water generated by the thermal power plant and reheat it for heating. It generates wastewater during power generation and heat supply, which generally requires wastewater treatment.

[0003] As described in the existing patent document "CN216303478U A wastewater circulation supply device for thermal power plants", it can filter wastewater by isolating and filtering impurities in the wastewater with a filter plate, thereby preventing impurities in the wastewater from clogging the water pipe, and a vibration rod is provided to vibrate the filter plate, thereby preventing impurities from clogging the filter plate.

[0004] The aforementioned patent document proposes a filtering structure to prevent excessive dirt from being discharged and clogging the water pipe. Furthermore, vibration is used to cause dirt trapped on the filter plate to fall and be discharged to the left, thus avoiding clogging. However, this method has the following drawbacks: Simply using vibration to assist in filtering dirt to concentrate it to one side cannot completely prevent clogging of the filter structure. Over long-term use, dirt can become lodged in the filter holes of the filter structure, causing them to become clogged. Vibration prevents the dirt from being discharged, thus causing clogging. Therefore, a wastewater treatment machine that avoids clogging is proposed to address the above-mentioned problem. Summary of the Invention

[0005] In this embodiment, a wastewater treatment machine that avoids clogging is provided. It has a self-cleaning function and can perform self-cleaning of the filter mechanism to avoid clogging of the filter mechanism.

[0011] Furthermore, the active roller and the driven roller are both composed of two cylinders, a connecting shaft and a synchronous wheel. The connecting shaft is fixedly installed between the two cylinders, and the synchronous wheel is fixedly sleeved on the connecting shaft. A synchronous belt is wound between the synchronous wheel of the active roller and the synchronous wheel of the driven roller. A filter soft plate is fixedly installed on the synchronous belt, and the length of the filter soft plate is less than the length of the synchronous belt. A number of filter holes are evenly opened on the plate surface of the filter soft plate.

[0012] Furthermore, a cam is fixedly mounted on the connecting shaft of the active roller, a U-shaped connecting rod is provided below the cam, a rotating wheel is rotatably sleeved on the middle part of the U-shaped connecting rod, and the rotating wheel is in contact with the wheel surface below the cam, and a movable rod is fixedly mounted on one side of the U-shaped connecting rod.

[0017] The benefit of the present application lies in that: compared with the prior art, the wastewater treatment machine proposed in the present application has a self-cleaning function, which can perform self-cleaning of the filter mechanism to avoid clogging of the filter mechanism; specifically, the second motor drives the active roller to rotate, and the synchronous wheel on the active roller will rotate together, and cooperate with the synchronous wheel on the driven roller to make the synchronous belt move.

After the insertion rod moves along the length direction of the filter hole, that is, after the insertion rod moves to the end position of the filter hole, the electromagnet is powered off and loses its magnetic effect. Since the cam does not squeeze the rotating wheel, the elastic force of the third spring causes the movable rod to move upward, the rotating wheel is abutted against the bottom of the cam, and the insertion rod and the filter hole are pulled out, thereby meeting the cleaning needs of the slender filter hole;

[0019] To sum up, the present application realizes the cleaning of all filter holes in the length direction of the filter soft plate through the continuous transportation provided by the second motor.

[0041] The housing 1 is provided with a self-cleaning filter mechanism, and the filter mechanism is located on the left side of the sewage outlet 20;

[0042] Specifically, the wastewater is filtered by the filter mechanism, and the wastewater flows from the top of the filter mechanism to the bottom of the filter mechanism to achieve filtration. The filtered water enters the hopper 7 and can be discharged through the drain pipe 8 and the second valve 9.

[0043] It should be further explained that the dirt filtered by the filter mechanism is collected into the dirt discharge cover 4 through the dirt outlet 20 , and when the dirt in the dirt discharge cover 4 is discharged, the first valve 5 is opened and the dirt is discharged through the drain pipe 6 .

[0044] like Figure 1 As shown, in a specific implementation, support frames 10 are fixedly installed on both sides of the shell 1, and a mounting bottom bar 11 is fixedly installed on the bottom of the support frame 10. A plurality of mounting holes 13 are provided on the mounting bottom bar 11. The support frame 10 and the mounting bottom bar 11 are used to elevate the entire wastewater treatment machine so that the drain pipe 8 maintains a certain distance from the ground, providing an installation structure for the whole. The mounting holes 13 provide installation holes, which can be fixed to the ground and can be fixed by screws, bolts, etc.

[0045] like Figure 2 As shown, further, a first motor 3 is fixedly installed on the top of the shell 1, and a stirring mechanism 14 is fixedly installed on the bottom end of the output shaft of the first motor 3. The stirring mechanism 14 is arranged inside the shell 1, and the stirring mechanism 14 is located above the filtering mechanism to provide a stirring and mixing function. The stirring mechanism 14 is driven to rotate by the first motor 3, thereby providing stirring treatment for the wastewater above the filtering mechanism. After the sewage generated by the thermal power plant is added with a treatment agent, such as a flocculant, it enters the upper part of the shell 1 through the feeding port 2, and is driven to rotate by the first motor 3 to stir, thereby facilitating the mixing of the agent and the sewage.

[0046] like Figure 3 、 Figure 4 、 Figure 5 as well as Figure 7As shown, as a specific technical solution, the filtering mechanism is tilted, and the tilted setting facilitates the collection of filtered dirt to the right side of the filtering mechanism. The filtering mechanism includes: a second motor 21, an active roller 15 and a driven roller 16. The front end of the active roller 15 is fixedly connected to the output shaft end of the second motor 21, and the rear end of the active roller 15, the front end of the driven roller 16 and the rear end of the driven roller 16 are all rotatably mounted with a block 22; a vertical groove 29 is provided on the inner wall of the housing 1, and the block 22 is slidably mounted inside the vertical groove 29, and a first spring 23 is fixedly mounted on the top and bottom of the block 22. The first spring 23 is fixedly mounted on the top and bottom of the block 22. One end away from the block 22 is fixedly connected to the wall of the vertical slot 29. An electromagnetic vibrator 35 is installed at the bottom of the block 22 and the bottom of the housing of the second motor 21. The electromagnetic vibrator 35 can provide vibration. The filter mechanism is installed at four corners and around the four blocks 22 and the second motor 21. The vertical slot 29 provides a vertical guiding movement. Combined with the elasticity of the first spring 23, the filter mechanism can vibrate in the upper and lower positions, which is convenient for assisting the discharge of dirt and facilitating its discharge into the dirt outlet 20, thereby facilitating its discharge into the dirt outlet 4. The above design can initially prevent the filter mechanism from being blocked.

[0047] like Figure 5 、 Figure 7 As shown, as a specific technical solution, two baffles 30 are fixedly installed on the groove wall at the groove position of the vertical groove 29, and the baffles 30 are in contact with the block 22. A second spring 31 is provided in the vertical groove 29. The side of the block 22 away from the active roller 15 and the driven roller 16 is fixedly installed with one end of the second spring 31, and the other end of the second spring 31 is in contact with the groove wall of the vertical groove 29; wherein the second spring 31 is in a compressed state, providing pressure for the block 22, and cooperating with the blocking effect of the baffle 30, providing a clamping force for the installation of the block 22 in the vertical groove 29, thereby improving the friction force in the vertical groove 29 and providing a certain friction limit.

[0048] As a specific technical solution, Figure 4As shown, the active roller 15 and the driven roller 16 are both composed of two cylinders 24, a connecting shaft 25 and a synchronous wheel 26. The connecting shaft 25 is fixedly installed between the two cylinders 24, and the synchronous wheel 26 is fixedly sleeved on the connecting shaft 25. A synchronous belt 18 is wound between the synchronous wheel 26 of the active roller 15 and the synchronous wheel 26 of the driven roller 16. A filter soft plate 17 is fixedly installed on the synchronous belt 18, and the length of the filter soft plate 17 is less than the length of the synchronous belt 18. A plurality of filter holes 19 are evenly opened on the plate surface of the filter soft plate 17. Specifically, the active roller 15 is driven to rotate by the second motor 21, so that a synchronous wheel 26 is rotated, and the synchronous wheel 26 on the driven roller 16 is cooperated to realize the transportation of the synchronous belt 18. The filter soft plate 17 will move together with the synchronous belt 18 to realize transportation.

[0049] like Figure 6 、 Figure 8 as well as Figure 9As shown, as a specific technical solution, a cam 32 is fixedly installed on the connecting shaft 25 of the active roller 15, and a U-shaped connecting rod 33 is provided below the cam 32. The middle part of the U-shaped connecting rod 33 is rotatably sleeved with a rotating wheel 34, and the rotating wheel 34 is in contact with the wheel surface below the cam 32. A movable rod 27 is fixedly installed on one side of the U-shaped connecting rod 33; the end of the movable rod 27 is slidably installed with a positioning slot 28 provided on the inner wall of the shell 1, and a third spring 37 is provided inside the positioning slot 28; the top of the third spring 37 is fixedly connected to the slot wall of the positioning slot 28, and the third spring 37 is fixedly connected to the slot wall of the positioning slot 28. The bottom end of the spring 37 is fixedly connected to the rod surface of the movable rod 27, and the bottom end of the positioning slide 28 is fixedly fitted with an electromagnet 38. The movable rod 27 is an iron rod structure; a plurality of plug rods 36 are fixedly installed at equal intervals along the length direction at the bottom of the movable rod 27. When the second motor 21 drives the active roller 15 to rotate, the connecting shaft 25 on the active roller 15 will rotate together, thereby causing the cam 32 to rotate together. Through the shape of the cam 32, the rotating wheel 34 below the cam 32 can be provided with downward pressure at different positions, so that the rotating wheel 34 can be moved downward to different height positions, and the U-shaped connecting rod 33 can be used to make the movable rod 27 rotate. The movable rod 27 moves downward together, and the third springs 37 at both ends of the movable rod 27 provide a reset elastic force to ensure that the rotating wheel 34 is always in contact with the bottom of the cam 32, thereby realizing the adjustment of the movable rod 27 to different height positions. The insertion rod 36 thereon will move up and down with the movable rod 27 to adjust the height position, and is used to be inserted into the filter hole 19 to push out the dirt stuck in the filter hole 19, and then pull it out to complete the cleaning, thereby avoiding clogging; at the same time, when the movable rod 27 moves to the lowest end, the insertion rod 36 is inserted into the filter hole 19, and the second motor 21 continues to drive the rotation , through the action of the electromagnet 38, the iron rod can be magnetically attracted, and the magnetic force can keep the insertion rod 36 continuously inserted into the filter hole 19 for cleaning the length direction of the filter hole 19 in this application. After the insertion rod 36 moves along the length direction of the filter hole 19, that is, after the insertion rod 36 moves to the end position of the filter hole 19, the electromagnet 38 is powered off and loses its magnetic effect. Since the cam 32 does not squeeze the rotating wheel 34, the elastic force of the third spring 37 causes the movable rod 27 to move upward, the rotating wheel 34 is abutted against the bottom of the cam 32, and the insertion rod 36 and the filter hole 19 are pulled out, thereby meeting the cleaning needs of the slender filter hole 19.

[0050] A control cabinet 12 is fixedly mounted on the outer shell wall of the housing 1, and the control cabinet 12 is electrically connected to the first motor 3, the second motor 21, the electromagnetic vibrator 35 and the electromagnet 38. The entire wastewater treatment machine is controlled by the control cabinet 12, and a single-chip microcomputer controller or a PLC controller can be used in the control cabinet 12 to achieve control.

[0051] Instructions for use: The present application proposes a wastewater treatment machine that avoids clogging. When in use, an external power supply is used for power supply. After the sewage generated by the thermal power plant is added with a treatment agent, such as a flocculant, it enters the upper part of the shell 1 through the feeding port 2. The stirring mechanism 14 is driven by the first motor 3 to rotate and stir, so as to facilitate the mixing of the agent and the sewage. After mixing, it is filtered by the filtering mechanism, specifically through the filtering holes 19 on the filter soft plate 17. Since the filtering mechanism is tilted, the filtered dirt is easily gathered to the right. Further, an electromagnetic vibrator 35 is provided to provide vibration. The filtering mechanism is provided with three blocks 22 and a second motor 21 for installation at the four sides and four corners. The vertical groove 29 provides a vertical guiding movement. With the elasticity of the first spring 23, the vibration of the upper and lower positions of the filtering mechanism can be realized, so as to facilitate the discharge of dirt and facilitate discharge into the sewage outlet 20, thereby facilitating discharge into the sewage cover 4.

[0052] The filtered water enters the hopper 7 and is then discharged through the drain pipe 8 and the second valve 9. When the dirt in the dirt cover 4 is discharged, the first valve 5 is opened and the dirt is discharged through the drain pipe 6.

[0053] Furthermore, compared with the prior art, the wastewater treatment machine for avoiding clogging proposed in the present application has a self-cleaning function, which can perform self-cleaning of the filter mechanism to avoid clogging of the filter mechanism; specifically, the second motor 21 drives the active roller 15 to rotate, and the synchronous wheel 26 on the active roller 15 will rotate together, and cooperate with the synchronous wheel 26 on the driven roller 16 to make the synchronous belt 18 move. When the synchronous belt 18 moves, the filter soft plate 17 will also move accordingly. The purpose of its movement is to make the filter holes 19 in the length direction of the filter soft plate 17 pass through the cleaning position in turn, so as to realize the cleaning of all the filter holes 19 in the length direction, and each cleaning can realize the cleaning of the same longitudinal position of the filter soft plate 17; the second motor 21 drives the active roller 15 to rotate When the cam 32 is in the downward direction, the connecting shaft 25 on the active roller 15 will rotate together, thereby causing the cam 32 to rotate together. The shape of the cam 32 can provide downward pressure at different positions for the rotating wheel 34 below the cam 32, so that the rotating wheel 34 can move down to different height positions. The U-shaped connecting rod 33 is used to make the movable rod 27 move downward together, and the third springs 37 at both ends of the movable rod 27 provide a reset elastic force to ensure that the rotating wheel 34 is always in contact with the bottom of the cam 32, thereby realizing the adjustment of the different height positions of the movable rod 27. The insertion rod 36 thereon will move up and down with the movable rod 27 to adjust the height position, and is used to be inserted into the filter hole 19 to eject the dirt stuck in the filter hole 19, and then pull it out to complete the cleaning, thereby playing a role in avoiding blockage.

[0054] At the same time, when the movable rod 27 moves to the lowest end, the insertion rod 36 is inserted into the filter hole 19, and the second motor 21 continues to drive it to rotate. Through the action of the electromagnet 38, the iron rod can be magnetically attracted. Through the magnetic action, the insertion rod 36 can be kept continuously inserted into the filter hole 19 for cleaning the length direction of the filter hole 19 in the present application. After the insertion rod 36 moves along the length direction of the filter hole 19, that is, after the insertion rod 36 moves to the end position of the filter hole 19, the electromagnet 38 is powered off and loses its magnetic effect. In addition, because the cam 32 does not squeeze the rotating wheel 34, the elastic force of the third spring 37 causes the movable rod 27 to move upward, the rotating wheel 34 is abutted against the bottom of the cam 32, and the insertion rod 36 and the filter hole 19 are pulled out, thereby meeting the cleaning requirements of the slender filter hole 19;

[0055] To sum up, the present application realizes the cleaning of all the filter holes 19 in the length direction of the filter soft plate 17 through the continuous transportation provided by the second motor 21. At the same time, the driving force of the second motor 21 can realize the up and down driving of the insertion rod 36, which can be inserted into the filter hole 19 and pulled out from the filter hole 19 to achieve cleaning. Furthermore, it can keep the insertion rod 36 inserted into the filter hole 19 and move a certain distance to meet the cleaning requirements of the slender filter hole 19, so that the entire wastewater treatment machine has the function of filtering and processing, and at the same time can avoid clogging of the filter mechanism.

[0056] The circuits, electronic components and modules involved are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by this application does not involve improvements to software and methods.

[0057] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
