Description

Technical Field

[0001] The present invention relates to the field of wastewater treatment, and particularly to a wastewater treatment device for Chinese herbal medicine processing. Background Art

[0002] In the process of Chinese herbal medicine processing, it usually involves multiple links such as cleaning, soaking, steaming, and extraction. These processes will generate a large amount of wastewater containing complex components such as drug residues, plant tissues, pigments, and organic matters. If this kind of wastewater is directly discharged without effective treatment, it will not only cause water pollution and damage the ecological environment, but also may have a persistent impact on the surrounding soil and groundwater. In particular, some components such as alkaloids and glycosides contained in Chinese herbal medicines have certain toxicity or biological activity, increasing the difficulty and environmental risk of wastewater treatment;

[0003] At present, traditional Chinese herbal medicine wastewater treatment methods mostly use precipitation, filtration, biodegradation or physical and chemical methods (such as coagulation precipitation, activated carbon adsorption, etc.) for preliminary purification. However, these methods generally have problems such as low treatment efficiency, high operating cost, complex equipment structure, large floor area, and poor adaptability to complex components in wastewater, and it is difficult to meet the actual needs of Chinese herbal medicine processing enterprises for wastewater discharge up to standard or recycling;

[0004] In addition, some existing wastewater treatment equipment has technical defects such as inconvenient maintenance, easy blockage, lack of pertinence in the treatment process, and inability to achieve continuous treatment during use, which restricts the sustainable development of the Chinese herbal medicine processing industry. Therefore, there is an urgent need for a wastewater treatment device for Chinese herbal medicine processing with reasonable structure, high treatment efficiency, strong adaptability, and easy operation and maintenance to improve the wastewater treatment effect, reduce the environmental protection cost of enterprises, and promote the green development of the Chinese medicine industry.

[0005] After retrieval, it is found that the prior art publication number is CN115849535B, which discloses a wastewater treatment device, including an installation frame, a precipitate reaction tank, a sedimentation tank, a wastewater tank, etc.; the precipitate reaction tank is arranged on one side of the installation frame, the sedimentation tank is arranged on the top of the precipitate reaction tank, the lower part of the sedimentation tank is located in the precipitate reaction tank, and the sedimentation tank is communicated with the precipitate reaction tank. The wastewater tank is arranged on the side of the installation frame away from the precipitate reaction tank. This scheme squeezes the slide rod downward by the downward movement of the return liquid pipe, and then opens the sedimentation tank to discharge the precipitate at the lower part of the sedimentation tank. At the same time, the circular partition plate moves downward to block the sedimentation tank, so that the wastewater will not flow into the precipitate reaction tank. In this way, the separation of wastewater and precipitate and the discharge of precipitate can be achieved for subsequent secondary treatment of wastewater.

[0006] Therefore, based on the above retrieval and in combination with the existing technology, there is an existing wastewater treatment device that does not have a control structure for the dosing and release of purification agents, making it difficult to achieve precise treatment of impurities in wastewater, and the treatment effect is easily affected. At the same time, it does not have an automatic sewage discharge or structure cleaning function, so sedimentation or blockage is likely to occur inside the device, increasing the maintenance difficulty and affecting the long-term operation efficiency.

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] Example 1: Please refer to Figures 1 to 5 , Figure 9, A wastewater treatment device for traditional Chinese medicine processing, including a reaction tank body 1. The reaction tank body 1 includes a tank body 11 and a tank cover 12. Specifically, the tank body 11 and the tank cover 12 are fixedly installed by bolts. The outer wall circumference of the tank body 11 is equidistantly welded and fixed with four support feet 111. The support feet 111 are used to provide the stability of the tank body 11. A drain port 112 is provided at the bottom end of the tank body 11. A filter screen for filtering impurities is installed inside the drain port 112. A water valve is provided at the end of the drain port 112 to control the drainage of the drain port 112. An inlet port 121 is opened on one side of the top surface of the tank cover 12. Sewage is discharged into the tank body 11 through the inlet port 121. A storage tank 2 is fixedly installed at the center of the top surface of the tank body 11 by bolts. An inorganic flocculant is stored in the storage tank 2. Specifically, the inorganic flocculant is polyaluminum chloride. Polyaluminum chloride has a good effect on removing pigments, and at the same time, it has low cost and fast sedimentation. The inorganic flocculant can aggregate suspended solids, organic macromolecules, pigments, and colloidal particles in water into flocs, so as to achieve sedimentation or air flotation removal. At the same time, after the inorganic flocculant itself adsorbs impurities, its volume significantly increases. The bottom ends of the storage tank 2 are respectively extended with a first discharge pipe 21 and a second discharge pipe 22. The bottom end of the first discharge pipe 21 passes through the tank cover 12 and is coaxially fixedly installed with a detection component 3. The detection component 3 includes an installation cylinder 31. Specifically, the installation cylinder 31 is vertically penetrated. A pressure feeding component 4 and a discharging component 5 are respectively installed inside the installation cylinder 31. An installation component 6 is fixedly installed on the inner wall of the reaction tank body 1 by bolts. The installation component 6 includes an installation bracket 61. A quantitative component 7 and a driving component 8 are installed on the installation bracket 61. The bottom end of the second discharge pipe 22 abuts against the quantitative component 7. The driving component 8 is connected with an air pump 9. The air pump 9 is fixedly installed on the outer wall of the tank body 1 by bolts. The filter plate 46 of the pressure feeding component 4 forms a pressure feedback linkage with the driving component 8 through a hydraulic cylinder 43.

[0047] Please refer to Figures 3 to 5 , An installation ring 311 is provided at the top end of the inner wall of the installation cylinder 31. A discharge pipe 33 is coaxially fixedly installed on the inner wall of the installation ring 311. A cylinder cover 32 is fixedly installed on the top surface of the installation cylinder 31 by bolts. Specifically, a sealing ring is clamped between the cylinder cover 32 and the installation cylinder 31. The sealing ring can effectively improve the sealing performance between the installation cylinder 31 and the cylinder cover 32. The top end of the discharge pipe 33 passes through the cylinder cover 32 and is coaxially fixedly connected with the bottom end of the first discharge pipe 21. A sliding groove 331 is opened on the outer wall of the discharge pipe 33. An outlet groove 332 is opened at the bottom end of the sliding groove 331. Specifically, the inorganic flocculant in the storage tank 2 enters the discharge pipe 33 through the first discharge pipe 21. A triangular block is provided on the inner bottom surface of the discharge pipe 33. The inclined surface of the triangular block can facilitate the discharge of the inorganic flocculant from the outlet groove 332. An electric push rod 34 is fixedly installed on the outer wall of the installation ring 311. An inlet groove 312 is opened at the bottom end of the outer wall of the installation cylinder 31.

[0048] Example 2: Please refer to Figures 3 to 8, A wastewater treatment device for traditional Chinese medicine processing, which is different from that in Embodiment 1. The material pressing component 4 includes a sliding sleeve 41. The sliding sleeve 41 is slidably sleeved on the outer wall of the discharge pipe 33. A sliding convex block 411 is provided on the inner wall of the sliding sleeve 41. The sliding convex block 411 is adapted to the size of the sliding groove 331. The sliding convex block 411 is slidably connected in the sliding groove 331. The telescopic end of the electric push rod 34 is fixedly connected to the top surface of the sliding sleeve 41. Specifically, an extension plate is provided at the top end of the outer wall of the sliding sleeve 41. The telescopic end of the electric push rod 34 is fixedly connected to the extension plate. The electric push rod 34 is used to control the up and down sliding of the sliding sleeve 41 on the outer wall of the discharge pipe 33, and the sliding convex block 411 slides up and down in the sliding groove 331 to switch the opening and closing state of the discharge slot 332. A through hole is opened on the bottom surface of the sliding sleeve 41. An installation plate 412 is provided at a position near the bottom end of the inner wall of the sliding sleeve 41. A moving block 42 is connected to the bottom surface of the installation plate 412 through a first spring 421. The outer wall size of the moving block 42 is adapted to the inner wall size of the through hole. A connecting rope is fixedly connected to the top surface of the moving block 42. The end of the connecting rope away from the moving block 42 passes through the installation plate 412 and is fixedly connected to the bottom end of the discharge pipe 33. Specifically, when the discharge slot 332 is opened, the moving block 42 closes the through hole, and the inside of the sliding sleeve 41 is in a closed state. The inorganic flocculant enters the sliding sleeve 41 through the discharge slot 332 until the space between the sliding sleeve 41 and the discharge pipe 33 is filled with the inorganic flocculant. Then, the electric push rod 34 is started to drive the sliding sleeve 41 to move downward on the outer wall of the discharge pipe 33 until the sliding convex block 411 closes the discharge slot 332, and the inorganic flocculant in the discharge pipe 33 can no longer be discharged into the inside of the sliding sleeve 41. At this time, the amount of inorganic flocculant in the sliding sleeve 41 is sufficient to adsorb and purify the sewage with the maximum concentration limit inside the installation cylinder 31. The electric push rod 34 continues to push the sliding sleeve 41 to move downward on the outer wall of the discharge pipe 33. At this time, the connecting rope is straightened, the first spring 421 is compressed, and the moving block 42 is disengaged from the clamping connection with the through hole. The inorganic flocculant in the sliding sleeve 41 is discharged into the installation cylinder 31 through the through hole to react with the sewage. An extension rod 413 is fixedly welded to the bottom end of the outer wall of the sliding sleeve 41. Two hydraulic cylinders 43 are symmetrically installed on the outer wall of the sliding sleeve 41. A connecting arc pipe 44 is jointly connected to the top ends of the outer walls of the two hydraulic cylinders 43. Specifically, the connecting arc pipe 44 is a flexible hose, and the length of the connecting arc pipe 44 has a certain margin. The connecting arc pipe 44 is communicated with the inside of the two hydraulic cylinders 43. The end of the connecting arc pipe 44 away from the two hydraulic cylinders 43 is connected to a buffer cylinder 45. The buffer cylinder 45 is fixedly installed on the outer wall of the installation cylinder 31. A filter plate 46 is slidably sleeved on the outer wall of the sliding sleeve 41. Two first piston rods 461 are symmetrically installed on the top surface of the filter plate 46. The two first piston rods 461 are respectively slidably connected in the two hydraulic cylinders 43. Specifically, the filter plate 46 is made of polyethylene. A number of filter holes are equidistantly opened on the top surface circumference of the filter plate 46. A filter net is adhesively bonded to the bottom surface of the filter plate 46. A sliding hole penetrating up and down is opened on the top surface of the filter plate 46.The inner wall size of the sliding hole is adapted to the outer wall size of the sliding sleeve 41. A switch plate 47 is hinged to the bottom surface of the filter plate 46. The switch plate 47 is adapted to the size of the sliding hole. A torsion spring is installed between the hinge part of the switch plate 47 and the filter plate 46. Specifically, the torsion spring has a force to flip the switch plate 47. When the filter plate 46 is not working, the switch plate 47 is pushed open by the outer wall of the sliding sleeve 41. At this time, the torsion spring is compressed. When the filter plate 46 moves downward, the switch plate 47 is no longer under the pressure of the sliding sleeve 41, and the torsion spring releases its elastic force to drive the switch plate 47 to flip, so that the switch plate 47 closes the sliding hole, thereby preventing impurities from entering the upper space of the filter plate 46.,

[0049] Please refer to Figures 5 to 8, the material discharging assembly 5 includes an inner cylinder 51. The bottom surface of the inner cylinder 51 is fixedly connected to the bottom end of the extension rod 413. The outer wall size of the inner cylinder 51 is adapted to the inner wall size of the installation cylinder 31. A communication groove 511 for water inlet is provided at the bottom end of the outer wall of the inner cylinder 51. Specifically, the sliding sleeve 41 drives the inner cylinder 51 to move synchronously on the inner wall of the installation cylinder 31 through the extension rod 413. In the state where the electric push rod 34 does not work, the positions of the communication groove 511 and the water inlet groove 312 correspond to each other. The sewage in the cylinder body 11 enters the inside of the inner cylinder 51 after passing through the water inlet groove 312 and the communication groove 511. When the electric push rod 34 drives the sliding sleeve 41 to move downward, the sliding sleeve 41 drives the inner cylinder 51 to move downward through the extension rod 413, so that the communication groove 511 is misaligned with the water inlet groove 312, and the sewage cannot enter the installation cylinder 31 again. The inorganic flocculant reacts with the sewage inside the inner cylinder 51 to aggregate the suspended solids, organic macromolecules, pigments and colloidal particles in the sewage into flocs. At the same time, after the inorganic flocculant adsorbs impurities itself, its volume increases significantly. A plurality of clamping grooves 512 are equidistantly arranged on the circumference of the bottom end of the outer wall of the inner cylinder 51. A positioning ring 52 is coaxially and fixedly installed on the bottom surface of the installation cylinder 31. A plurality of clamping teeth are equidistantly arranged on the inner circumference of the positioning ring 52. The sizes of the clamping teeth and the clamping grooves 512 are adapted to each other. An extension bracket 521 is provided on the bottom surface of the positioning ring 52. A rotating rod 513 is provided at the center of the bottom surface of the inner cylinder 51. The bottom end of the rotating rod 513 passes through the extension bracket 521 and is coaxially and fixedly installed with a driven gear 53. A second spring 54 is sleeved on the outer wall of the rotating rod 513. Specifically, the top end of the second spring 54 abuts against the bottom surface of the inner cylinder 51, and the bottom end of the second spring 54 abuts against the top surface of the extension bracket 521. A stepping motor 55 is fixedly installed on the outer wall of the extension bracket 521 through bolts. The rotating shaft of the stepping motor 55 is coaxially and fixedly installed with a driving gear 56. The driving gear 56 is meshed and clamped with the driven gear 53. Specifically, the model of the stepping motor 55 is [model number]. In the normal working state, the positions of the clamping teeth and the clamping grooves 512 are misaligned, so that the inner cylinder 51 cannot move downward. When the impurities in the inner cylinder 51 need to be removed, the stepping motor 55 is started to drive the driving gear 56 to rotate. The driving gear 56 drives the driven gear 53 to rotate. The driven gear 53 drives the inner cylinder 51 to rotate through the rotating rod 513, so that the positions of the clamping teeth and the clamping grooves 512 correspond to each other. The electric push rod 34 is used to drive the sliding sleeve 41 to move downward, compressing the second spring 54. The sliding sleeve 41 drives the inner cylinder 51 to move downward through the extension rod 413, so that the communication groove 511 of the inner cylinder 51 is exposed to the outside of the installation cylinder 31. The sewage and impurities inside the inner cylinder 51 are discharged through the communication groove 511.

Specifically, a slide rail is provided on the inner wall of the sliding ring 611, and a convex ring is provided on the outer wall of the rotating disk 71. The convex ring is slidably connected in the slide rail, and the slide rail has a limiting and guiding effect on the convex ring to prevent the rotating disk 71 from falling off. The bottom end of the second discharge pipe 22 abuts against the top surface of the rotating disk 71. A sliding cylinder 711 is fixedly installed at the center of the bottom surface of the rotating disk 71, and a sliding rod 72 is slidably inserted into the sliding cylinder 711. Specifically, a convex strip is provided on the outer wall of the sliding rod 72, and a groove is provided on the inner wall of the sliding cylinder 711.

An air inlet 811 is provided on the bottom surface of the driving cylinder 81. A gas transmission pipe 91 is coaxially and fixedly connected to the air inlet 811. The end of the gas transmission pipe 91 away from the driving cylinder 81 passes through the cylinder body 11 and is connected to the air pump 9. Specifically, the air pump 9 supplies air to the inside of the driving cylinder 81. A second piston rod 82 is slidably connected inside the driving cylinder 81. A fourth spring 83 is sleeved on the outer wall of the second piston rod 82. An adjustment disc 62 is fixedly installed at the top end of the second piston rod 82. The adjustment disc 62 corresponds to the position of the rotating disc 71. The sliding rod 72 is slidably inserted at the center of the adjustment disc 62. The rotating gear 721 is located directly below the adjustment disc 62. The bottom end of the sliding cylinder 74 abuts against the top surface of the adjustment disc 62. A discharge port that penetrates up and down is provided on the top surface of the adjustment disc 62. Specifically, the second piston rod 82 drives the adjustment disc 62 to move up and down. By changing the distance between itself and the rotating disc 71, the adjustment disc 62 drives the sliding cylinder 74 to move up and down inside the fixed cylinder 73, indirectly adjusting the capacity of the fixed cylinder 73 and the sliding cylinder 74. An air outlet pipe 812 is provided at the bottom end of the outer wall of the driving cylinder 81. A ball valve 84 is slidably installed inside the air outlet pipe 812. A fifth spring 841 is fixedly connected to the outer wall of the ball valve 84. Specifically, a contact ring is provided on the inner wall of the air outlet pipe 812, and the outer wall of the ball valve 84 is in close contact with the inner wall of the contact ring. A blocking ring is provided at the end of the air outlet pipe 812. The end of the fifth spring 841 away from the ball valve 84 is fixedly connected to the blocking ring. A liquid outlet pipe 813 is provided at the top end of the outer wall of the driving cylinder 81. The liquid outlet pipe 813 is connected to the buffer cylinder 45 through a rubber pipe. Specifically, the inside of the driving cylinder 81 is divided into an upper chamber and a lower chamber by the piston of the second piston rod 82. The upper chamber of the driving cylinder 81, the buffer cylinder 45, and the two hydraulic cylinders 43 are all filled with hydraulic oil. A communicating pipe 85 is coaxially and fixedly installed at the end of the air outlet pipe 812. The end of the communicating pipe 85 away from the air outlet pipe 812 is fixedly connected to a telescopic cylinder 86. The telescopic cylinder 86 is fixedly installed on the bottom surface of the adjustment disc 62 through bolts. Specifically, an air inlet pipe 861 is provided on the front surface of the telescopic cylinder 86. The end of the communicating pipe 85 away from the air outlet pipe 812 is coaxially and fixedly connected to the air inlet pipe 861. The communicating pipe 85 is a flexible pipe, and the length of the communicating pipe 85 has a certain margin. An air discharge pipe 862 is provided at a position near the rear end of the outer wall of the telescopic cylinder 86. A third piston rod 87 is slidably connected to the inner wall of the telescopic cylinder 86. A sixth spring 88 is sleeved on the outer wall of the third piston rod 87. The rear end of the third piston rod 87 is fixedly connected to a rack 89. The rack 89 is meshed and engaged with the rotating gear 721. Specifically, the air pump 9 inflates the lower chamber of the driving cylinder 81. The increased air pressure in the lower chamber pushes the second piston rod 82 to move upward, compressing the fourth spring 83. The second piston rod 82 drives the adjustment disc 62 to move upward. The adjustment disc 62 drives the sliding cylinder 74 to move up and down inside the fixed cylinder 73, indirectly adjusting the capacity of the fixed cylinder 73 and the sliding cylinder 74. The internal space of the upper chamber becomes smaller, and the hydraulic oil inside the upper chamber enters the buffer cylinder 45 through the rubber pipe.The hydraulic oil inside the buffer cylinder 45 enters the two hydraulic cylinders 43 through the connecting arc pipe 44. The hydraulic oil inside the two hydraulic cylinders 43 increases and pushes the first piston rod 461 to move downward. The first piston rod 461 drives the filter plate 46 to move downward. The filter plate 46 filters the impurities adsorbed by the inorganic flocculant. The clean water is filtered, and the impurities are compressed below the filter plate 46 until the impurities are compressed to a certain density. At this time, the first piston rod 461 can no longer move downward, and no more hydraulic oil can be injected into the hydraulic cylinder 43. Since the hydraulic oil cannot be compressed, the second piston rod 82 can no longer move upward at this time. At this time, the height of the adjustment disc 62 is constant, and the space inside the fixed cylinder 73 and the sliding cylinder 74 remains constant. The air pump 9 continues to work, and the air pressure in the lower chamber of the driving cylinder 81 increases again. After the air pressure reaches a certain threshold, the gas pushes the ball valve 84 to disengage from the abutting ring, and the fifth spring 841 is compressed, so that the air outlet pipe 812 is communicated with the connecting pipe 85. The high-pressure gas enters the telescopic cylinder 86 through the connecting pipe 85. The high-pressure gas pushes the third piston rod 87 to move backward, compressing the sixth spring 88. The third piston rod 87 drives the rack 89 to move. The rack 89 drives the sliding rod 72 to rotate through the meshing engagement with the rotating gear 721. The sliding rod 72 drives the rotating disc 71 to rotate. When the fixed cylinder 73 and the sliding cylinder 74 pass directly below the second discharge pipe 22, the inorganic flocculant inside the second discharge pipe 22 enters the storage space formed by the fixed cylinder 73 and the sliding cylinder 74. After the storage space formed by the fixed cylinder 73 and the sliding cylinder 74 is filled with the inorganic flocculant, it continues to rotate until it passes directly above the discharge port of the adjustment disc 62. The inorganic flocculant inside the fixed cylinder 73 and the sliding cylinder 74 falls into the sewage inside the cylinder body 11 through the discharge port. The inorganic flocculant purifies and adsorbs the sewage inside the cylinder body 11, so as to realize the quantitative feeding of the flocculant according to the concentration of impurities in the sewage, save the dosage of the inorganic flocculant, and avoid the waste of resources.

[0052] The working principle of the present invention is: when the device starts to operate, the wastewater enters the cylinder body 11 inside the reaction cylinder body 1 through the water inlet 121 on one side of the top surface of the cylinder head 12. A drain port 112 and a filter screen are provided at the bottom of the cylinder body 11 for controlling the discharge of the subsequent purified water;

[0053] A storage tank 2 is fixedly installed at the center of the top surface of the cylinder body 11 through bolts. The storage tank 2 is filled with inorganic flocculants such as polyaluminum chloride. The flocculants flow into the detection assembly 3 through the first discharge pipe 21 at the bottom of the storage tank. The detection assembly 3 includes an installation cylinder 31. The installation cylinder 31 runs through up and down, and a pressure feeding assembly 4 and a discharge assembly 5 are sequentially installed inside the cylinder for regulating the process of releasing the flocculant;

[0054] When it is necessary to release the flocculant, the electric push rod 34 drives the sliding sleeve 41 to move upward. The sliding bump 411 moves upward to avoid the discharge chute 332, opening the discharge passage. The inorganic flocculant enters the sliding sleeve 41. There is a through hole at the bottom of the sliding sleeve 41, and the opening state of the through hole is controlled by the moving block 42. After the loading in the sliding sleeve 41 is completed, the electric push rod 34 pushes the sliding sleeve 41 downward to close the discharge chute 332. During the downward movement of the sliding sleeve 41, the connecting rope is tightened, causing the first spring 421 to compress and push the moving block 42 away from the through hole, allowing the flocculants to smoothly drain into the installation cylinder 31 and contact and react with the wastewater entering the interior of the installation cylinder 31;

[0055] At the same time, the built-in cylinder 51 in the discharge assembly 5 is linked to the bottom end of the sliding sleeve 41 through the extension rod 413. There is a communication groove 511 on the outer wall of the built-in cylinder 51 for water inlet, which corresponds to the water inlet groove 312 on the outer wall of the installation cylinder 31. When the electric push rod 34 is in a stationary state, the operation of sewage entering the installation cylinder 31 is completed. When the electric push rod 34 continues to press down the sliding sleeve 41, the communication groove 511 is misaligned and closed to prevent new sewage from continuing to enter, ensuring that the flocculation reaction takes place in a closed environment;

[0056] Then start the air pump 9, which inflates the lower chamber of the driving cylinder 81. The increased air pressure in the lower chamber pushes the second piston rod 82 upward, compressing the fourth spring 83. The second piston rod 82 drives the adjusting plate 62 to move upward, and the adjusting plate 62 drives the sliding cylinder 74 to move up and down inside the fixed cylinder 73, indirectly adjusting the capacity of the fixed cylinder 73 and the sliding cylinder 74. The internal space of the upper chamber becomes smaller, and the hydraulic oil inside the upper chamber enters the buffer cylinder 45 through the rubber tube. The hydraulic oil inside the buffer cylinder 45 enters the two hydraulic cylinders 43 through the connecting arc tube 44. The hydraulic oil inside the two hydraulic cylinders 43 increases and The first piston rod 461 is pushed downward, and the first piston rod 461 drives the filter plate 46 to move downward. The filter plate 46 filters the impurities adsorbed by the inorganic flocculant, and the clean water is filtered. The impurities are compressed under the filter plate 46 until the impurities are compressed to a certain density. At this time, the first piston rod 461 can no longer move downward, and the hydraulic cylinder 43 can no longer be injected with hydraulic oil. Since the hydraulic oil cannot be compressed, the second piston rod 82 can no longer move upward. At this time, the height of the adjustment plate 62 is constant, and the space inside the fixed cylinder 73 and the sliding cylinder 74 remains constant. The air pump 9 continues to work. The air pressure in the lower chamber of the driving cylinder 81 increases again. When the air pressure reaches a certain threshold, the gas pushes open the ball valve 84 to disengage it from the abutment ring, and the fifth spring 841 is compressed, so that the air outlet pipe 812 is connected with the connecting pipe 85. The high-pressure gas enters the telescopic cylinder 86 through the connecting pipe 85. The high-pressure gas pushes the third piston rod 87 to move backward, compressing the sixth spring 88. The third piston rod 87 drives the rack 89 to move. The rack 89 drives the sliding rod 72 to rotate by engaging with the rotating gear 721. The sliding rod 72 drives the rotating disk 71 to rotate. The fixed cylinder 73 and the sliding cylinder 74 pass through the second discharge port. When the inorganic flocculant in the second discharge pipe 22 is directly below the tube 22, the inorganic flocculant in the second discharge pipe 22 enters the storage space formed by the fixed cylinder 73 and the sliding cylinder 74. After the storage space formed by the fixed cylinder 73 and the sliding cylinder 74 is filled with the inorganic flocculant, it continues to rotate until it passes directly above the discharge port of the adjustment disk 62. The inorganic flocculant in the fixed cylinder 73 and the sliding cylinder 74 falls into the sewage in the cylinder body 11 through the discharge port. The inorganic flocculant purifies and adsorbs the sewage in the cylinder body 11, thereby realizing quantitative addition of flocculant according to the concentration of impurities in the sewage, saving the amount of inorganic flocculant and avoiding waste of resources.

[0057] After the sewage inside the cylinder body 11 completes the reaction with the inorganic flocculant, if it is necessary to clean the impurities inside the detection component 3, the stepper motor 55 installed on the extension bracket 521 can be started, which drives the driven gear 53 and the rotating rod 513 to rotate through the driving gear 56, so that the built-in cylinder 51 rotates to the position where the engaging groove 512 is aligned with the engaging teeth, and then the electric push rod 34 is started again, and the sliding sleeve 41 continues to press down, compressing the second spring 54, pushing the built-in cylinder 51 downward, exposing the connecting groove 511, and completing the discharge of impurities inside the built-in cylinder 51; at this point, the work of the device is completed.

[0058] As described above, it is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
