Description

Technical Field

[0002] In the daily operation of production units in power plants or other industrial and mining enterprises, it is usually necessary to carry out necessary purification treatment on wastewater so that the wastewater can be recycled and reused, or the treated water that meets the corresponding environmental protection standards can be discharged.

[0003] Generally speaking, in order to ensure the efficient operation of equipment such as cooling systems and steam generators, power plants usually need a large amount of high-purity water to add to the circulating water system. Considering the daily production and equipment operation costs of the enterprise, it is necessary to purify the wastewater generated by the power plant itself so that the water can be recycled to ensure the continuous and stable operation of related equipment.

[0004] At present, when purifying wastewater, it is usually necessary to first flocculate the untreated wastewater to remove impurities in the water. However, due to the limitations of the structure and function of the conventional treatment devices currently used in power plants, the filtering and cleaning effects of impurities generated after flocculation treatment of wastewater are not ideal, resulting in some impurities generated after flocculation still being sent to the downstream treatment process along with the water body, which will not only have an adverse effect or even damage the equipment in the downstream process, but also seriously affect the overall purification effect and treatment efficiency of the wastewater.

[0025] Compared with the above-mentioned background technology, during the operation and use of the wastewater treatment equipment provided by the utility model, when it is necessary to implement flocculation treatment on the wastewater, the cover plate is reliably overlapped on the top of the treatment box and the box mouth is closed, while the drain pipe and the sewage valve are kept closed, and the wastewater raw water is injected into the treatment chamber through the water inlet pipe until the wastewater raw water inventory in the treatment chamber meets the current working condition requirements and then the injection of water into the treatment chamber is stopped; then the feed valve is opened, and an appropriate amount of flocculant is injected into the treatment chamber through the feed pipe, and then the feed valve is closed, and then the flocculant in the treatment chamber is waited for to flocculate the wastewater raw water. During the flocculation treatment and after the flocculation treatment is completed, the salvage net box is driven to move downward from the initial position at a higher position by the salvage lifting push rod until the salvage net box is completely immersed in the wastewater in the treatment chamber, and then the salvage moving block is driven by the salvage translation assembly to move back and forth in the horizontal direction, thereby driving the salvage net box to translate synchronously, so that when the salvage net box passes through different positions in the treatment chamber, the suspended floccules at different positions can be effectively collected.

In addition, after the water level in the treatment chamber is lowered to an appropriate position, the cover plate can be lifted by the cover plate lifting drive mechanism to unblock the box opening and reopen it, after which the salvage net box can be cleaned through the box opening to remove the flocculants and dirt collected in the salvage net box. After the salvage net box is cleaned, the cover plate can be driven down again by the cover plate lifting drive mechanism until the cover plate re-seals the box opening for the next flocculation treatment operation.As a result, the suspended flocculants after the flocculation treatment of the wastewater in the treatment chamber are collected and treated by the salvage net box, and the deposited flocculants and dirt at the bottom of the treatment chamber are effectively scraped off by the scraper, thereby efficiently removing impurities such as flocculants and dirt generated after the flocculation treatment of the wastewater, avoiding these flocculants and dirt from being discharged along with the wastewater to the downstream wastewater purification treatment process, avoiding the adverse effects of flocculants on other downstream purification equipment, thereby greatly improving the purification efficiency of the wastewater and optimizing the overall purification effect of the wastewater accordingly.

[0046] In a specific embodiment, Figure 1 and Figure 2 As shown, the wastewater treatment equipment provided by the utility model includes a frame 10 and a treatment box 101 fixedly connected to the frame 10, the treatment box 101 has a treatment chamber 102 capable of accommodating wastewater, the top of the treatment box 101 has a box opening 103 connected to the treatment chamber 102, a cover plate 104 is installed above the treatment box 101, the cover plate 104 can overlap and fit with the treatment box 101 in the vertical direction to close the box opening 103, and a cover plate lifting drive mechanism capable of driving the cover plate 104 to lift and reciprocate in the vertical direction is fixedly installed on the frame 10.

[0047] A bracket 11 is fixedly connected to the top surface of the cover plate 104, and a flocculation box 111 with a flocculation chamber inside is fixedly connected to the bracket 11. The top of the flocculation box 111 has a feeding port 112 for feeding flocculants into the flocculation box 111. When the flocculants in the flocculation box 111 are insufficient, the flocculants can be added to the flocculation box 111 through the feeding port 112 to ensure the working condition requirements of the current flocculation treatment. A feed pipe 113 is fixedly connected to the bottom of the flocculation box 111. The bottom end of the feed pipe 113 passes through the cover plate 104 and is connected to the treatment chamber 102. The top end of the feed pipe 113 passes through the flocculation box 111 and is connected to the flocculation chamber. A feed valve 114 is fixedly connected to the middle of the feed pipe 113.

[0048] A water inlet pipe 105 is provided on the side wall at one end of the treatment box 101 for waste water to enter the treatment chamber 102, a drain pipe 106 is provided on the side wall at the other end of the treatment box 101 for water to be discharged from the treatment chamber 102, a sewage outlet 12 is provided on the bottom wall of the treatment box 101 near the drain pipe 106 at one end for flocculants to be discharged from the treatment chamber 102, a sewage outlet 121 connected to the downstream of the sewage outlet 12 is fixedly connected to the bottom of the treatment box 101, a sewage valve 122 is provided in the middle of the sewage outlet 121, and the heights of the water inlet pipe 105, the drain pipe 106 and the sewage outlet 12 decrease in sequence.

[0049] A salvage net box 13 capable of accommodating flocculants is movably arranged in the processing chamber 102, a salvage moving block 14 and a salvage translation assembly capable of driving the salvage moving block 14 to reciprocate in the horizontal direction are arranged on the top of the processing chamber 102, the salvage net box 13 is located below the salvage moving block 14 and can move along with the salvage moving block 14, and a salvage lifting push rod 141 capable of reciprocating and telescoping in the vertical direction is connected between the salvage moving block 14 and the salvage net box 13, the top end of the salvage lifting push rod 141 is fixedly connected to the bottom of the salvage moving block 14, and the bottom end of the salvage lifting push rod 141 is hinged to the outer wall of the salvage net box 13, and a salvage flipping mechanism capable of driving the salvage net box 13 to flip around a hinge axis between the salvage lifting push rod 141 and the salvage moving block 14 is also fixedly installed.

[0050] A scraper 15 extending in the horizontal direction is movably arranged below the salvage net box 13, and the bottom edge of the scraper 15 is tightly fitted with the bottom inner wall of the processing chamber 102. A scraper translation assembly capable of driving the scraper 15 to reciprocate in the horizontal direction is fixedly installed in the processing chamber 102, and the moving direction of the scraper 15 is perpendicular to its extension direction.

[0051] During the specific operation and use of the equipment, when flocculation treatment is required for wastewater, the cover plate 104 is reliably overlapped on the top of the treatment box 101 and the box port 103 is closed, while the drainage pipe 106 and the sewage valve 122 are kept closed, and the wastewater raw water is injected into the treatment chamber 102 through the water inlet pipe 105 until the stock of the wastewater raw water in the treatment chamber 102 meets the current working condition requirements and then the injection of water into the treatment chamber 102 is stopped. Then, the feed valve 114 is opened, and an appropriate amount of flocculant is injected into the treatment chamber 102 through the feed pipe 113, and then the feed valve 114 is closed, and then the flocculant in the treatment chamber 102 is waited for to flocculate the wastewater raw water.

[0052] During the flocculation process and after the flocculation process is completed, the salvage net box 13 is moved down from the initial position at a higher position by the salvage lifting push rod 141 until the salvage net box 13 is completely immersed in the wastewater in the treatment chamber 102, and then the salvage translation assembly drives the salvage moving block 14 to move back and forth in the horizontal direction, thereby driving the salvage net box 13 to translate synchronously, so that the salvage net box 13 can effectively collect the flocculants suspended at different positions when it passes through different positions in the treatment chamber 102. During this period, the salvage net box 13 can be flipped by the salvage flipping mechanism to an angle that facilitates the flocculants to enter the inside of the salvage net box 13, so as to improve the collection efficiency of the salvage net box 13 for the flocculants. After the suspended flocculants are basically collected, the salvage net box 13 can be driven to flip and reset through the salvage flipping mechanism to prevent the flocculants collected in the salvage net box 13 from escaping from the salvage net box 13, and the salvage lifting push rod 141 can be retracted upward to drive the salvage net box 13 to move upward and reset to the initial position. At the same time, the water inlet pipe 105 is kept closed and the drain pipe 106 is opened, so that the wastewater from which the flocculants have been cleaned in the treatment chamber 102 can be discharged from the treatment chamber 102 through the drain pipe 106.

[0053] When the water level in the treatment chamber 102 drops below the drain pipe 106, the drain valve 122 can be opened to allow the bottom wastewater and flocculants in the treatment chamber 102 to be discharged into the drain pipe 121 through the drain port 12, and then discharged to the downstream collection device or treatment device through the drain pipe 121. During this period, the scraper 15 can be driven by the scraper translation assembly from the initial position far away from the drain port 12 to gradually approach the drain port 12, thereby using the fitting structure between the scraper 15 and the bottom inner wall of the treatment chamber 102 to scrape off the flocculants and other dirt attached to the bottom inner wall of the treatment chamber 102, and push these scraped flocculants and dirt to the drain port 12 together, so that these flocculants and dirt can be completely discharged from the treatment chamber 102 through the drain port 12 and the drain pipe 121, thereby achieving complete removal of the flocculants and dirt in the treatment chamber 102 after flocculation treatment. After the flocculants and dirt at the bottom of the treatment chamber 102 are scraped off, the scraper 15 is driven by the scraper translation assembly to translate horizontally in the reverse direction to reset, so that the scraper 15 returns from the sewage outlet 12 to the initial position away from the sewage outlet 12, completing the entire scraping operation.

[0054] In addition, after the water level in the treatment chamber 102 is lowered to an appropriate position, the cover plate 104 can be lifted by the cover plate lifting drive mechanism to unblock the box opening 103 and reopen it. After that, the salvage net box 13 can be cleaned through the box opening 103 to remove the flocculants and dirt collected in the salvage net box 13. After the salvage net box 13 is cleaned, the cover plate 104 can be driven to descend again by the cover plate lifting drive mechanism until the cover plate 104 re-seals the box opening 103 for the next flocculation treatment operation.

[0055] As a result, the suspended flocculants after the flocculation treatment of the wastewater in the treatment chamber 102 are collected and treated by the salvage net box 13, and the deposited flocculants and dirt at the bottom of the treatment chamber 102 are effectively scraped off by the scraper 15, thereby efficiently removing impurities such as flocculants and dirt generated after the flocculation treatment of the wastewater, avoiding these flocculants and dirt from being discharged along with the wastewater to the downstream wastewater purification treatment process, avoiding the adverse effects of flocculants on other downstream purification equipment, thereby greatly improving the purification efficiency of the wastewater, and optimizing the overall purification effect of the wastewater accordingly.

[0056] Generally, considering the equipment layout space and assembly conditions under most working conditions, the processing box 101 is a hollow rectangular parallelepiped structure, the processing chamber 102 also corresponds to a rectangular parallelepiped cavity, and the arrangement position of the sewage outlet 12 also corresponds to the top corners of the two adjacent edges of the bottom of the processing chamber 102. In order to facilitate the intuitive understanding of the technical details and practical application effects of this solution, the assembly position and arrangement direction of other matching parts involving the processing chamber 102 and the processing box 101 as the assembly structure reference in this solution can also refer to the corresponding structure of the processing chamber 102 and the processing box 101 with a rectangular parallelepiped shape as shown in the figure.

[0057] Specifically, the scraper translation assembly includes two lower screw rods 151 and a scraper motor capable of driving the lower screw rods 151 to rotate on a fixed axis. The two lower screw rods 151 are arranged in parallel and symmetrically in the horizontal direction, and the two ends of the lower screw rods 151 are respectively rotatably connected to a pair of inner side walls in the processing chamber 102 that are perpendicular to the axis of the lower screw rods 151. Considering that the processing chamber 102 is usually a rectangular cavity, the two ends of the lower screw rod 151 here are respectively connected to a group of relatively arranged vertical side walls of the processing chamber 102, and the rotational coordination between the end of the lower screw rod 151 and the inner wall of the processing chamber 102 is realized through a bearing.

[0058] The scraper translation assembly also includes two scraper sliders 152 which are symmetrically arranged in the horizontal direction and move in a one-to-one correspondence with the lower screw rod 151. The scraper sliders 152 are adaptively sleeved on the lower screw rod 151 through internal screw holes and threads. The two scraper sliders 152 are linked and connected by a scraper connecting plate 153 to achieve synchronous movement. The scraper 15 is located below the scraper connecting plate 153, and the two ends of the scraper 15 are respectively hinged to the scraper sliders 152 in a one-to-one correspondence. Generally, the scraper 15 can be directly hinged and installed on the scraper slider 152, or a scraper adapter plate 158 can be linked to the scraper slider 152 so that the two ends of the scraper 15 can be directly hinged to the scraper adapter plate 158 to avoid interference with the main structure of the scraper slider 152 caused by the direct hinged assembly of the scraper 15 and the main structure of the scraper slider 152, thereby ensuring the main structural strength and horizontal movement stability of the scraper slider 152. The scraper connecting plate 153 is provided with a scraper turning mechanism capable of driving the scraper sliding block 152 to turn around a hinge axis between the scraper connecting plate 153 and the scraper sliding block 152 .

[0059] When it is necessary to clean the flocculent and dirt accumulated at the bottom of the treatment chamber 102 and attached to the inner wall of the bottom of the treatment chamber 102, the scraper motor is used to drive the lower screw 151 to rotate on a fixed axis, thereby using the threaded adapter structure between the lower screw 151 and the screw hole of the scraper slider 152 to drive the scraper slider 152 to move along the axial direction of the lower screw 151, and the scraper connecting plate 153 is used to drive the scraper 15 to move horizontally toward the position of the sewage outlet 12 synchronously with the scraper slider 152. During this movement, the edge of the scraper 15 The scraper 15 is always in contact with the inner wall of the treatment chamber 102, so as to scrape the inner wall of the treatment chamber 102 by the translational movement of the scraper 15, thereby scraping off the floccules and dirt accumulated at the bottom of the treatment chamber 102 and attached to the inner wall at the bottom of the treatment chamber 102, and pushing the floccules and dirt to the sewage outlet 12 along with the translational movement of the scraper 15, and finally discharged from the treatment chamber 102 through the sewage outlet 12, and then discharged to the corresponding downstream treatment equipment or station through the sewage pipe 121. In this way, the floccules and dirt at the bottom of the treatment chamber 102 are thoroughly cleaned, and the floccules and dirt are prevented from remaining in the treatment chamber 102 and causing adverse effects on the next batch of wastewater flocculation process treatment, and the floccules and dirt are prevented from being discharged to the downstream purification treatment station along with the wastewater after flocculation treatment and causing adverse effects on the downstream process equipment.

[0060] After a single scraping treatment is completed, the scraper 15 can be driven to flip upward appropriately by means of the scraper flipping mechanism so that the bottom edge of the scraper 15 is out of contact with the bottom inner wall of the treatment chamber 102, and then the scraper motor drives the lower screw 151 to rotate in the opposite direction, thereby driving the scraper slider 152 to translate in the opposite direction and reset, and thereby driving the scraper 15 to translate in the opposite direction synchronously through the scraper connecting plate 153, so that the scraper 15 gradually moves away from the sewage outlet 12, until the scraper 15 is moved to the initial position away from the sewage outlet 12, so as to facilitate the scraping treatment of the bottom flocs in the next batch of flocculation treatment process. Since the scraper 15 has been flipped upwards under the drive of the scraper flipping mechanism during this translational reset period, the scraper 15 will not have any rigid contact or structural interference with the bottom inner wall of the processing chamber 102 during the entire translational reset process, which effectively avoids structural impact and damage between the scraper 15 and the inner wall of the processing chamber 102, and makes the movement and reset process of the scraper 15 smoother and more efficient; after the scraper 15 returns to the initial position, the scraper flipping mechanism can be used to drive the scraper 15 to stretch and reset downward, so that the bottom edge of the scraper 15 is fully fit with the bottom inner wall of the processing chamber 102 again, so as to ensure the scraping treatment effect of the next batch.

[0061] On this basis, a scraper flip positioning plate 154 is protrudingly provided on the outer wall of the scraper connecting plate 153 close to the sewage outlet 12. The scraper flipping mechanism is a scraper push rod 155 which can reciprocate and extend and tiltably connected between the scraper flip positioning plate 154 and the scraper 15. The top end of the scraper push rod 155 is hinged to the bottom of the scraper flip positioning plate 154, and the bottom end of the scraper push rod 155 is hinged to the outer wall of the scraper 15 close to the sewage outlet 12. It is not difficult to understand that the inclined arrangement structure of the scraper push rod 155 here means that in the horizontal direction, the distance between the top end of the scraper push rod 155 and the vertical center line of the scraper 15 is greater than the distance between the bottom end of the scraper push rod 155 and the vertical center line of the scraper 15. Therefore, the extension of the scraper push rod 155 can be used to drive the bottom edge of the scraper 15 to expand to the lower limit position, so that the bottom edge of the scraper 15 can be fully fitted with the bottom inner wall of the processing chamber 102, thereby ensuring the corresponding flocculant and dirt scraping effect; and the contraction of the scraper push rod 155 can drive the bottom edge of the scraper 15 to flip up to the upper limit position, so that the bottom edge of the scraper 15 can be out of contact with the bottom inner wall of the processing chamber 102 and fit with an appropriate clearance, thereby ensuring that when the scraper 15 moves horizontally to reset, it will not cause structural interference, friction or rigid contact with the inner wall of the processing chamber 102, thereby avoiding non-working structural damage to the scraper 15 and the inner wall of the processing chamber 102.

[0062] The scraper flip positioning plate 154 can provide sufficient assembly space and reliable structural support for the top of the scraper push rod 155, thereby ensuring the assembly strength of the scraper push rod 155 and making its reciprocating motion more stable and reliable.

[0063] Generally, the hinged connection between the two ends of the scraper push rod 155 and the corresponding scraper flip positioning plate 154 and the scraper 15 can be achieved through a hinge shaft and a hinge seat, or through a ball joint mechanism. In actual application, it can be flexibly selected and adjusted according to specific assembly conditions and working conditions. In addition, the scraper push rod 155 can be a rod-shaped component driven by a cylinder, an oil cylinder or an electric cylinder as a core power mechanism. Specifically in this scheme, the push rod mechanism involved in other components or devices can refer to the corresponding component structure layout for understanding. Of course, according to the different assembly requirements of different components and devices, other types of axial reciprocating drive mechanisms can also be used to achieve the telescopic action of the corresponding push rod. The hinge structure between the push rod and the corresponding matching part can also refer to the hinge shaft mechanism or ball joint mechanism described above for corresponding adaptation application. Considering that the action principle and design requirements of the corresponding adaptation component structure of each push rod are relatively similar, its actual working principle and application method can refer to the corresponding understanding here and will not be repeated.

[0064] Specifically, Figure 6 As shown, a scraper baffle 156 is protruding from the bottom of the scraper connecting plate 153, and the scraper baffle 156 is located on the side of the scraper 15 away from the sewage outlet 12, and the side wall of the scraper baffle 156 abuts against the side wall of the scraper 15. When the scraper 15 moves in parallel to scrape off the floccules on the inner wall at the bottom of the processing chamber 102, the scraper baffle 156 can provide reliable structural support for the scraper 15 at the rear side of the moving direction of the scraper 15, so as to prevent the scraper 15 from turning over backward, loosening or dislocating due to the impact and resistance of floccules, dirt and wastewater during the translation process, and effectively improve the structural stability and action reliability of the scraper 15 in the floccules scraping process, so that the scraping efficiency of the floccules and dirt at the bottom of the corresponding processing chamber 102 can be further improved, and the corresponding floccules and dirt scraping treatment effect is more thorough.

[0065] More specifically, if Figure 4As shown, scraper guide grooves 157 extending in the horizontal direction are arranged one by one on a pair of inner side walls in the processing chamber 102 which are parallel to the axis of the lower screw 151. The two scraper guide grooves 157 are arranged parallel and symmetrically in the horizontal direction. The lower screws 151 are rotatably connected to the scraper guide grooves 157 one by one, and the scraper sliders 152 are slidably installed in the scraper guide grooves 157 one by one. The scraper guide groove 157 can provide sufficient accommodating space and certain structural protection for the lower screw 151, so as to prevent the lower screw 151 from protruding from the main extension surface of the inner wall of the processing chamber 102 and affecting the water diversion and processing space in the processing chamber 102; at the same time, the scraper guide groove 157 can also provide sufficient structural support and structural protection for the scraper slider 152. In actual applications, the scraper guide groove 157 can be set as a dovetail groove, and the edge of the scraper slider 152 can be correspondingly set as a dovetail structure, so as to achieve reliable alignment assembly and smooth sliding adaptation between the scraper slider 152 and the scraper guide groove 157 through the dovetail adaptation structure.

[0066] On the other hand, combined with reference Figure 3 As shown, the salvage translation assembly includes two upper screws 142 and a salvage translation motor 143 capable of driving the upper screws 142 to rotate on a fixed axis. The two upper screws 142 are arranged in parallel and symmetrically along the horizontal direction, and the two ends of the upper screws 142 are rotatably connected to a pair of inner side walls in the processing chamber 102 that are perpendicular to the axis of the upper screws 142. The salvage moving block 14 is adaptively sleeved on the upper screws 142 through the internal screw hole threads.

[0067] The top of the salvage net box 13 has a box opening 131 for flocculants and water to pass through, the bottom wall and each side wall of the salvage net box 13 are penetrated with a plurality of drainage holes 132 for water to pass through, and the bottom end of the salvage lifting push rod 141 is hinged to one of the side walls of the salvage net box 13.

[0068] Generally, the salvage net box 13 is a rectangular parallelepiped structure, with a box opening 131 at the top and a metal plate or engineering plastic plate with certain structural rigidity at the bottom, and each side thereof is surrounded by a filter screen 133. Accordingly, a plurality of drainage holes 132 may be correspondingly passed through the bottom plate, and the drainage holes 132 at the side are mesh holes on each filter screen 133. The rectangular parallelepiped structure of the salvage net box 13 is determined by its rectangular parallelepiped frame structure of metal material or engineering plastic material. As shown in the figure, the bottom end of the salvage lifting push rod 141 may be hinged to the frame of the salvage net box 13.

[0069] When it is necessary to salvage the flocculants suspended in the wastewater in the treatment chamber 102, the salvage flipping mechanism is first used to drive the salvage net box 13 to flip so that the box mouth 131 is arranged in the horizontal direction, and the salvage lifting push rod 141 is extended to move the salvage net box 13 downward to a suitable height in the wastewater in the treatment chamber 102, and then the salvage translation motor 143 is started to drive the upper screw 142 to rotate on a fixed axis, thereby utilizing the threaded cooperation between the screw hole in the salvage moving block 14 and the upper screw 142 to drive the salvage moving block 14 to move horizontally along the axial direction of the upper screw 142, thereby utilizing the salvage lifting push rod 141 as a transmission connection structure to drive the salvage net box 13 to move horizontally synchronously with the salvage moving block 14, and since the box mouth 131 is in a horizontal arrangement state, the flocculants suspended in the wastewater in the treatment chamber 102 The flocculants can more conveniently enter the salvage net box 13 through the box opening 131, and the wastewater mixed with the flocculants entering the salvage net box 13 can be discharged from the salvage net box 13 through the drainage holes 132; when the suspended flocculants in the wastewater in the processing chamber 102 are salvaged and processed, or when a large amount of flocculants are collected in the salvage net box 13, the operation of the salvage translation motor 143 is stopped to stop the parallel movement of the salvage net box 13 together with the salvage moving block 14, and the salvage flipping mechanism is used to drive the salvage net box 13 to reset and flip, so that the box opening 131 is restored to the state of being at the top of the salvage net box 13 and arranged vertically upward, and then the salvage lifting push rod 141 is contracted to drive the salvage net box 13 to move up to the initial height position to complete a single suspended flocculant salvage processing operation.

[0070] Furthermore, the salvage flip mechanism is a salvage flip push rod 144 that can reciprocate and extend and tilt between the salvage moving block 14 and the salvage net box 13. The top end of the salvage flip push rod 144 is hinged to the bottom of the salvage moving block 14, and the bottom end of the salvage flip push rod 144 is hinged to the edge of the top surface of the salvage net box 13 away from the salvage lifting push rod 141. The salvage flip push rod 144 and the salvage lifting push rod 141 are arranged and matched with each other in the moving direction of the salvage moving block 14. Similar to the tilted arrangement structure of the scraper push rod 155, the tilted arrangement structure of the salvage flip push rod 144 helps to further improve the flipping efficiency and accuracy of the salvage net box 13, ensuring that the box mouth 131 can accurately and quickly switch between the horizontal orientation and the vertical orientation to meet the corresponding working conditions.

[0071] In addition, the salvage translation assembly includes two upper positioning blocks 145 fixed on the inner wall of the processing chamber 102, one end of the upper screw 142 is a positioning end which is inserted into the upper positioning block 145 one by one, and the positioning end is rotationally connected to the upper positioning block 145 through a coaxially arranged upper positioning bearing, and the other end of the upper screw 142 is a transmission end.

[0072] Please refer to Figure 3As shown, the salvage translation assembly further includes a sprocket 146 which is coaxially mounted and transmission-connected to the transmission end in a one-to-one correspondence, and the two sprockets 146 are transmission-connected via a chain 147, and the output end of the salvage translation motor 143 is transmission-connected to the transmission end of one of the upper screws 142. The transmission efficiency of the sprocket 146 is relatively high, and the salvage translation motor 143 is used to drive one of the upper screws 142 to rotate, and the transmission connection between the two sprockets 146 and the chain 147 can be used to achieve stable transmission between the two upper screws 142. The entire transmission process is stable and efficient, and the translation driving effect of the salvage moving block 14 can be effectively guaranteed.

[0073] Generally, the upper screw 142 and the lower screw 151 are arranged in parallel as shown in the figure. Taking into account the working conditions and process requirements in actual applications, the upper screw 142 and the lower screw 151 can be arranged vertically on the premise that the upper screw 142 and the lower screw 151 are both arranged horizontally, that is, the projections of the axis of the upper screw 142 and the axis of the lower screw 151 on the same horizontal plane are perpendicular to each other, so as to achieve different operating effects.

[0074] On the other hand, combined Figure 1 , Figure 2 and Figure 5 As shown, the cover lifting drive mechanism includes an upper adapter plate 16 fixedly connected to the side wall of the cover plate 104 and a side screw 161 rotatably connected to the side of the processing box 101 and extending in the vertical direction, and the upper adapter plate 16 protrudes from the side wall of the cover plate 104. The frame 10 has side positioning holes 162 located below the upper adapter plate 16 in a one-to-one correspondence along the vertical direction, and the top of the side screw 161 is fixedly connected to the middle of the upper adapter plate 16 in a one-to-one correspondence, so that the upper adapter plate 16 can move up and down synchronously with the side screw 161, and the bottom of the side screw 161 is aligned and plugged in with the side positioning holes 162 in a one-to-one correspondence. If the frame 10 has a plurality of leg structures as shown in the figure, the side positioning holes 162 can be arranged correspondingly at the top of the legs to ensure the alignment and plugging adaptation accuracy of each side positioning hole 162 and the side screw 161.

[0075] The cover lifting drive mechanism also includes a worm gear assembly and a lifting drive motor 165 fixedly installed in the middle of the outer wall of the processing box 101. The worm 163 of the worm gear assembly is transmission-connected to the output end of the lifting drive motor 165. The end of the worm 164 of the worm gear assembly is transmission-connected to a bevel gear 166. A threaded sleeve 167 is sleeved on the middle of the side screw 161. The inner wall of the threaded sleeve 167 is threadedly adapted to the outer wall of the side screw 161. The end of the threaded sleeve 167 is transmission-connected to a bevel gear ring 168 sleeved on the side screw 161 and meshing with the bevel gear 166. The threaded sleeve 167 is fixedly connected to the outer wall of the processing box 101 through a side positioning block 169, and the threaded sleeve 167 rotates with the side positioning block 169.

[0076] When the cover plate 104 needs to be lifted to open the box opening 103, the lifting drive motor 165 is started, and the lifting drive motor 165 is used to drive the worm gear assembly to operate, so as to use the meshing transmission between the bevel gear 166 and the bevel gear ring 168 to drive the threaded sleeve 167 to rotate synchronously, thereby using the threaded adapter structure between the threaded sleeve 167 and the side screw 161 to form an axial relative movement between the threaded sleeve 167 and the side screw 161. Since the threaded sleeve 167 is fixedly connected to the outer wall of the processing box 101, the axial relative movement process is realized by the axial rise of the side screw 161 itself, thereby driving the cover plate 104 to be lifted upward synchronously with the side screw 161. If the cover plate 104 needs to be lowered, it is only necessary to use the reverse operation of the lifting drive motor 165 to drive the above-mentioned transmission components to operate in the reverse direction.

[0077] It should be noted that the threaded sleeve 167 is inserted in the middle of the side positioning block 169, and the outer periphery of the threaded sleeve 167 is sleeved with a bearing that is inserted and matched with the side positioning block 169 to achieve relative rotation between the threaded sleeve 167 and the side positioning block 169, thereby ensuring the corresponding action requirements and transmission adaptation effect of the threaded sleeve 167. If necessary, a plurality of support plates or brackets can be arranged on the outer wall of the processing box 101 to ensure the reliable arrangement and stable support of the relevant components of the cover plate lifting drive mechanism.

[0078] In addition, if Figure 1 and Figure 2 As shown, a sewage hopper 123 is connected to the bottom of the sewage outlet 12, and the cross section of the inner cavity of the sewage hopper 123 decreases from top to bottom. The top of the sewage hopper 123 is fixedly connected to the bottom of the treatment box 101, and the bottom of the sewage hopper 123 is connected to the top of the sewage pipe 121. The upper wide and lower narrow structure of the sewage hopper 123 helps to steadily concentrate and guide the flocculants and dirt entering the sewage hopper 123 through the sewage outlet 12, so that they can be discharged into the sewage pipe 121 more smoothly, thereby further improving the discharge efficiency of the flocculants and dirt, and making their discharge smoother and more thorough.

[0079] In summary, it can be seen that during the operation and use of the wastewater treatment equipment provided in the utility model, when it is necessary to implement flocculation treatment on the wastewater, the cover plate is reliably overlapped on the top of the treatment box and the box mouth is closed, while the drain pipe and the drain valve are kept closed, and wastewater raw water is injected into the treatment chamber through the water inlet pipe until the wastewater raw water inventory in the treatment chamber meets the current working conditions and then the injection of water into the treatment chamber is stopped; thereafter, the feed valve is opened, and an appropriate amount of flocculant is injected into the treatment chamber through the feed pipe, and then the feed valve is closed, and then the flocculant in the treatment chamber is waited for to flocculate the wastewater raw water. During the flocculation treatment and after the flocculation treatment is completed, the salvage net box is driven to move downward from the initial position at a higher position by the salvage lifting push rod until the salvage net box is completely immersed in the wastewater in the treatment chamber, and then the salvage moving block is driven by the salvage translation assembly to move back and forth in the horizontal direction, thereby driving the salvage net box to translate synchronously, so that when the salvage net box passes through different positions in the treatment chamber, the suspended floccules at different positions can be effectively collected. During this period, the salvage net box can be flipped to an angle that facilitates the floccules to enter the inside of the salvage net box by the salvage flip mechanism, so as to improve the collection efficiency of the floccules by the salvage net box. After the suspended floccules are basically collected, the salvage net box can be driven to flip and reset by the salvage flip mechanism to prevent the floccules collected in the salvage net box from escaping from the salvage net box, and the salvage lifting push rod is retracted upward to drive the salvage net box to move upward and reset to the initial position, while keeping the water inlet pipe closed and opening the drain pipe, so that the wastewater that has been cleaned of floccules in the treatment chamber can be discharged from the treatment chamber through the drain pipe. When the water level in the treatment chamber drops below the drain pipe, the drain valve can be opened to allow the bottom wastewater and flocculants in the treatment chamber to be discharged into the drain pipe through the drain port, and then discharged to the downstream collection equipment or treatment equipment through the drain pipe; during this period, the scraper can be driven by the scraper translation assembly from the initial position far away from the drain port to gradually approach the drain port, thereby utilizing the fitting structure between the scraper and the inner wall of the bottom of the treatment chamber to scrape off the flocculants and other dirt attached to the inner wall of the bottom of the treatment chamber, and push these scraped flocculants and dirt to the drain port together, so that these flocculants and dirt are completely discharged from the treatment chamber through the drain port and the drain pipe, thereby achieving complete removal of the flocculants and dirt in the treatment chamber after flocculation treatment; after the flocculants and dirt at the bottom of the treatment chamber are scraped off, the scraper is driven by the scraper translation assembly to translate and reset horizontally in the opposite direction, so that the scraper returns from the drain port to the initial position far away from the drain port, completing the entire scraping operation. In addition, after the water level in the treatment chamber is lowered to an appropriate position, the cover plate can be lifted by the cover plate lifting drive mechanism to unblock the box opening and reopen it, after which the salvage net box can be cleaned through the box opening to remove the flocculants and dirt collected in the salvage net box. After the salvage net box is cleaned, the cover plate can be driven down again by the cover plate lifting drive mechanism until the cover plate re-seals the box opening for the next flocculation treatment operation.As a result, the suspended flocculants after the flocculation treatment of the wastewater in the treatment chamber are collected and treated by the salvage net box, and the deposited flocculants and dirt at the bottom of the treatment chamber are effectively scraped off by the scraper, thereby efficiently removing impurities such as flocculants and dirt generated after the flocculation treatment of the wastewater, avoiding these flocculants and dirt from being discharged along with the wastewater to the downstream wastewater purification treatment process, avoiding the adverse effects of flocculants on other downstream purification equipment, thereby greatly improving the purification efficiency of the wastewater and optimizing the overall purification effect of the wastewater accordingly.

[0080] The above is a detailed introduction to the wastewater treatment equipment provided by the utility model. This article uses specific examples to illustrate the principles and implementation methods of the utility model. The description of the above embodiments is only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
