Description

Technical Field

[0001] The invention belongs to the technical field of wastewater treatment, and specifically relates to a device and method for treating wastewater produced by an insecticide industry. Background Art

[0002] Pesticides, as chemical agents for pest control, will discharge a large amount of wastewater during the production process; this type of wastewater often contains a variety of toxic and harmful substances, such as organophosphorus, organochlorine, heavy metals, etc. If it is directly discharged into the natural environment without effective treatment, it will cause serious harm to the soil, water bodies, ecosystems and human health. Therefore, it must be purified. The treatment method is generally multi-stage treatment, which includes three stages: physical treatment, chemical treatment and biological treatment.

[0003] In the physical treatment stage, a screen is used. It is installed at the front end of the wastewater entering the multi-stage treatment facility and is mainly composed of a series of parallel bars. The spacing between these bars varies according to different treatment requirements, generally between 1 and 50 mm. Its function is to intercept various impurities mixed in the wastewater, such as unreacted raw material particles, product residues, packaging debris, fibers, etc., while the wastewater passes through the gaps between the bars. However, during operation, existing wastewater treatment devices often face the problem of impurities blocking the gaps between the bars. Because some impurities, especially sticky substances, fine fibers or flocs, are easy to adhere to and accumulate in the gaps, and are difficult to clean, as the blockage worsens, the wastewater cannot flow out of the blocked gaps, resulting in a continuous decrease in the effective water flow area of ​​the screen, which directly affects the output of wastewater in the physical treatment stage, thereby reducing the device's treatment efficiency for wastewater, making the device more limited when used.

The wastewater treated in the physical stage is discharged to the subsequent treatment stage through the output end of the docking pipeline for treatment operations.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) When the main magnetic sheet on the linkage square plate is completely aligned with one of the auxiliary magnetic sheets, the controller receives the information and controls the blocking horizontal plate to stop moving, so that the plurality of material removal square cylinders arranged horizontally on the blocking horizontal plate can be aligned with the plurality of horizontal gaps on the blocking grille. At this time, by starting the first electric telescopic device, its output end can drive the plurality of material removal square cylinders to move downward so that they can enter the gaps, thereby pushing the impurities accumulated in the gaps to the input end of the docking pipe, thereby avoiding the accumulation of impurities in the gaps and causing the blocking grille to be blocked, thereby avoiding the effective water flow area of ​​the blocking grille to be reduced, so that the water output of the wastewater after the physical treatment stage can be guaranteed, thereby improving the treatment efficiency of the device for wastewater, thereby reducing the limitations of the device during use; when the gap at this location is cleaned, the controller operates the blocking horizontal plate to continue to move to the next auxiliary magnetic sheet and repeats the above operation with the main magnetic sheet, so as to continuously clear the blocking grille and avoid its blockage, thereby improving the use effect of the device; (2) Move the guide empty box so that the two guide sliders on it move within the guide slide groove and the guide slide column, so that the guide spring is in a buffering state, thereby driving the resistance grille to move, so as to adjust the position of the resistance grille in the docking pipe, so that the resistance grille can adjust its position in time according to different usage conditions, for example, adjust the contact distance between the wastewater and the resistance grille according to the water pressure in the docking pipe, so as to avoid the resistance grille being subjected to strong impact due to the large distance from the wastewater during use, thereby reducing the limitation of the resistance grille during use; and the impurities in the wastewater are distributed differently, and adjusting the resistance grille to a position with a higher impurity concentration can more effectively intercept and capture impurities, improve the filtration efficiency, and at the same time avoid the resistance grille being fixed in one place for a long time for use, which causes excessive wear at that place in the docking pipe, thereby improving the life of the resistance grille during use, thereby improving the treatment effect of the device; (3) When it is necessary to disassemble the blocking grille, it is only necessary to release the limit setting of the stop bevel block. At this time, the blocking grille is continued to be pushed from the direction of the output end of the docking pipeline, so that the inclined surface of the stop bevel block contacts the inclined surface of the stop bevel groove, and then force is continued to be applied to the stop bevel block to make it move in the guide empty box, thereby releasing the limit setting of the blocking grille and completing the disassembly operation of the blocking grille. The installation and disassembly operations of the blocking grille are convenient and quick, and can be completed without the aid of any tools, thereby improving the use effect of the blocking grille, allowing the device to select and replace blocking grilles of different specifications as needed, thereby improving the wastewater treatment effect of the device and reducing the limitations of the device during use; (4) After the material-removing square cylinder pushes out the impurities in the gap, the second electric expansion joint is started so that its output end can drive the pressing square column to move away from the opening end of the material-removing square cylinder. At this time, the switch valve is in an open state, so that the suction force generated by its open end can suck the pushed impurities into the material-removing square cylinder. When the pressing square column is reset and moved by operating, the switch valve is closed at this time, so that the water in the material-removing square cylinder is discharged through the circular hole on the surface of the closing valve, and the absorbed impurities cannot be discharged, so that the impurities blocking the gap of the material-removing square cylinder can be collected, avoiding the existence of the blocking grille close to the input end of the docking pipe, which affects the flow rate and flow of the wastewater, thereby improving the wastewater treatment effect of the device, thereby further reducing the limitations of the device during use; (5) When the position of the resisting grille is adjusted, the guide spring is in a buffering state. The buffering force brought by the guide spring can prevent the resisting grille from hitting the docking pipe due to excessive force when moving, and can also reduce the impact force on the resisting grille when in use, thereby improving the stability of the resisting grille when moving; when the position of the resisting grille is adjusted, the third electric telescopic device is started so that its output end drives the guide plug to move and move into the guide slot, so that the guide empty box limit setting can be set, so as to prevent the resisting grille from moving due to non-human factors during use, thereby improving the safety of the resisting grille when in use, and when the resisting grille is limited and moved, the guide spring in the buffering state cannot be reset, and the elastic force brought by it can strengthen the contact strength and friction between the guide slot and the guide plug, thereby reducing the limitation of the resisting grille when in use, thereby further improving the use effect of the device; (6) By pulling the pull rod, the positioning square tube moves to the upper limit of the blocking horizontal plate, so that the positioning spring is in a buffering state, thereby driving the scraper to move, so that the distance between it and the blocking grid is adjustable, so that the scraper can be used in different usage conditions, reducing the limitations of the scraper when in use. At the same time, by moving the scraper downward, when the scraper has contacted the blocking grid, the positioning square tube continues to move to limit the movement at the positioning square column, so that the auxiliary spring is in a buffering state, so as to strengthen the contact strength between the scraper and the blocking grid, and avoid the scraper being unable to scrape due to insufficient contact strength between the two. The impurities adhering to the blocking grid are improved, and the use effect of the device is improved; when the position adjustment of the scraper is completed, the distance-adjusting square plate is loosened, and the distance-adjusting locking block on the distance-adjusting square plate is driven to pass through the locking square tube and connect with one of the locking square grooves through the resetting of the distance-adjusting spring, so that the positioning square tube on the scraper can be limited to the current position, and the scraper is prevented from moving due to non-human factors during use, thereby improving the safety of the scraper during use, and at the same time, the positioning spring in the buffer state cannot be reset, and the elastic force brought thereby strengthens the contact strength between the locking square groove and the distance-adjusting locking block, and reduces the limitations of the device during use; (7) The inclined surface of the stop bevel is facing the output end of the docking pipe, so that the straight surface of the stop bevel and the stop bevel groove is facing the input end of the docking pipe. When the input end of the docking pipe enters the wastewater, the pressure of the wastewater on the stop grid strengthens the contact strength of the straight surface between the stop bevel and the stop bevel groove. That is, the greater the pressure on the stop grid, the higher the contact strength and friction between the stop bevel and the stop bevel groove, which prevents the stop grid from being dislocated during use, further improves the installation and use effect of the stop grid, and thus further improves the wastewater treatment effect of the device; (8) The threaded displacement block is limited by the reciprocating movement of the guide block on the blocking horizontal plate at the guide cylinder, thereby driving the scraper on the blocking horizontal plate to move back and forth, so that it moves back and forth on the surface of the blocking grille, which can not only clean the impurities adhering to the blocking grille, but also push the impurities accumulated on the blocking grille to both sides, avoiding the accumulation of impurities in the gaps of the blocking grille, resulting in a reduction in the area for wastewater to pass, thereby improving the use effect of the blocking grille and improving the wastewater treatment effect of the device; at the same time, when the scraper is caused by too large impurities or other factors, When it is impossible to clean, when the impurities contact the inclined surface of the side of the scraper, an upward force is applied to the scraper, so that it moves within the positioning square tube through the positioning square column, so that the auxiliary spring is in a buffering state, so that the scraper can pass over the obstacle. When the scraper no longer contacts the impurities, the scraper is driven to return to the initial position through the reset of the auxiliary spring, so that the lower position of the resistance grille can be cleaned, which reduces the limitation of the device during use, improves the use effect of the device, and at the same time improves the cleaning effect of the scraper on the impurities on the resistance grille. (9) Place a suitable anti-movement grille into the output end of the docking pipe and move it so that the side edge of the anti-movement grille will contact the inclined surface of the stop bevel located in the docking pipe, so that it is subjected to pressure and moves in a limited position in the guide empty box, so that the stop spring is in a buffering state until the stop bevel block is completely located in the guide empty box. When the stop bevel block encounters the stop bevel groove on the side wall of the anti-movement grille, the stop bevel block is no longer limited and the reset of the stop spring drives the stop bevel block to reset and move into the stop bevel groove. At this time, no force is applied to the anti-movement grille, so that it is fixed in the current position, thereby completing the installation operation of the anti-movement grille. At this time, by starting the fourth electric telescopic device, its output end drives the friction square plate to move, so that it contacts the inside of the guide empty box, thereby limiting the stop bevel block to the current position, avoiding the stop bevel block from moving due to non-human factors when the anti-movement grille is fixed, thereby improving the installation effect of the anti-movement grille.

The guide base 15 is fixedly arranged on the blocking grille 2; the guide cylinder 14 and the guide block 13 are slidably matched; a reciprocating screw rod 16 is threadedly connected to the displacement block 12, and displacement bases 17 are installed at both ends of the reciprocating screw rod 16, and the displacement base 17 is fixedly arranged on the blocking grille 2; the reciprocating screw rod 16 and the guide cylinder 14 are vertically parallel to each other with the blocking grille 2 as the reference plane; a driving motor 18 is also installed on one of the displacement bases 17, and the output end of the driving motor 18 is connected to the reciprocating screw rod 16; two symmetrical positioning square tubes 19 are penetrated on the side of the blocking horizontal plate 3 away from the blocking grille 2, and the positioning square tube 19 and the blocking horizontal plate 3 slide Dynamic cooperation; a positioning square column 20 is slidably connected in the positioning square cylinder 19, and the two positioning square columns 20 are jointly connected to the scraper 21, and the scraper 21 is located between the blocking cross plate 3 and the blocking grille 2; a positioning spring 22 is sleeved on the positioning square cylinder 19, one end of the positioning spring 22 is fixedly connected to the blocking cross plate 3, and the other end is connected to a positioning limit plate 23, and the positioning limit plate 23 is fixedly connected to the end of the positioning square cylinder 19 away from the scraper 21; the two positioning limit plates 23 are jointly connected to a pull rod, and a locking square column 24 is installed on the pull rod, and a locking square cylinder 25 is slidably connected to the locking square column 24, and the locking square cylinder 25 is fixedly installed on the blocking cross plate 3; a distance adjustment locking unit is provided on the locking square cylinder 25; an auxiliary spring 26 is provided in the positioning square cylinder 19, and one end of the auxiliary spring 26 is fixedly connected to the inner bottom surface of the positioning square cylinder 19, and the other end is fixedly connected to the end point of the positioning square column 20 located in the positioning square cylinder 19; By starting the driving motor 18, the output end of the driving motor 18 drives the reciprocating screw rod 16 to rotate, so that the displacement block 12 connected by the thread moves back and forth at the guide cylinder 14 through the guide block 13 on the blocking horizontal plate 3, thereby driving the scraper 21 on the blocking horizontal plate 3 to move back and forth, so that it moves back and forth on the surface of the blocking grille 2, which can not only clean the impurities adhering to the blocking grille 2, but also push the impurities accumulated on the blocking grille 2 to both sides, so as to avoid the accumulation of impurities in the gap of the blocking grille 2, resulting in a reduction in the area through which wastewater passes, thereby improving the use effect of the blocking grille 2, so that the wastewater treatment effect of the device can be improved; at the same time, when the scraper 21 is affected by impurities, the impurities adhering to the blocking grille 2 can be removed, and the impurities adhering to the blocking grille 2 can be removed. When the impurities are too large or cannot be cleaned due to other factors, when the impurities contact the inclined surface on the side of the scraper 21, an upward force is applied to the scraper 21, so that it moves within the positioning square tube 19 through the positioning square column 20, so that the auxiliary spring 26 is in a buffering state, so that the scraper 21 can pass over the obstacle. When the scraper 21 no longer contacts the above-mentioned impurities, the scraper 21 is driven to return to the initial position through the reset of the auxiliary spring 26, so that the lower position of the resistance grille 2 can be cleaned, which reduces the limitations of the device during use, improves the use effect of the device, and at the same time improves the cleaning effect of the scraper 21 on the impurities on the resistance grille 2.

[0022] The distance adjustment locking unit of this embodiment includes a distance adjustment base 35 arranged on both sides of the locking square cylinder 25, and a distance adjustment cylinder 36 is fixedly installed on the side of the distance adjustment base 35.

At this time, by pulling the pull rod, the positioning square tube 19 is moved within the upper limit position of the anti-moving cross plate 3, so that the positioning spring 22 is in a buffering state, thereby driving the scraper 21 to move, so that the distance between it and the anti-moving grille 2 is adjustable, so that the scraper 21 can be used in different usage conditions, reducing the limitations of the scraper 21 when in use, and at the same time, by moving the scraper 21 downward, when the scraper 21 has contacted the anti-moving grille 2, the positioning square tube 19 continues to move to make it move within the positioning square column The limited movement at 20 makes the auxiliary spring 26 in a buffer state, thereby strengthening the contact strength between the scraper 21 and the blocking grille 2, avoiding the scraper 21 being unable to scrape off the impurities adhered to the blocking grille 2 due to insufficient contact force between the two, thereby improving the use effect of the device; when the position adjustment of the scraper 21 is completed, by loosening the distance adjusting square plate 37, the distance adjusting lock block 38 on the distance adjusting square plate 37 is driven to pass through the locking square tube 25 and connect with one of the locking square grooves 39 through the reset of the distance adjusting spring 40, so that the positioning square tube 19 on the scraper 21 can be limited to the current position, avoiding the scraper 21 from moving due to non-human factors during use, thereby improving the safety of the scraper 21 during use, and at the same time making the positioning spring 22 in the buffer state unable to reset, and the elastic force brought thereby strengthens the contact strength between the locking square groove 39 and the distance adjusting lock block 38, thereby reducing the limitations of the device during use.

[0023] The guide empty box 30 of the present embodiment is also provided with a lock replacement unit; the lock replacement unit includes a stopper slide 41 slidably connected to the guide empty box 30, and a stopper bevel 42 is provided on the side of the stopper slide 41 close to the stopper grille 2, and the stopper bevel 42 passes through the side of the guide empty box 30 close to the stopper grille 2 and the two are slidably matched; the inclined surface of the stopper bevel 42 is located in the docking pipe 1 and faces its output end; a stopper spring 43 is provided in the guide empty box 30, and one end of the stopper spring 43 is fixedly connected to the inside of the guide empty box 30 The other end is fixedly connected to the stop slide 41; the opposite sides of the stop bevel block 42 in the guide empty box 30 are provided with a fourth electric telescopic device 44, and a friction square plate 45 is installed on the output end of the fourth electric telescopic device 44, and the interior of the guide empty box 30 is located on the moving path of the friction square plate 45; the outer side wall of the blocking grille 2 is also provided with a stop bevel groove 46 with the same shape and position as the stop bevel block 42, and the stop bevel groove 46 and the stop bevel block 42 fit together; the inclined surface of the stop bevel block 42 is located on the moving path of the side edge of the blocking grille 2; When the device is treating wastewater, since the sizes of impurities in the wastewater are different, the device needs to use different gaps of the blocking grille 2 when in use. At this time, the appropriate blocking grille 2 is placed in the output end of the docking pipe 1 and moved, so that the side edge of the blocking grille 2 will contact the inclined surface of the stopping bevel 42 located in the docking pipe 1, so that it is subjected to pressure and moves in the guide empty box 30, so that the stopping spring 43 is in a buffering state until the stopping bevel 42 is completely located in the guide empty box 30. When the stopping bevel 42 encounters the stopping bevel groove 46 on the side wall of the blocking grille 2, the stopping bevel 42 is no longer limited and the resetting of the stopping spring 43 drives the stopping bevel 42 to reset and move into the stopping bevel groove 46. At this time, no force is applied to the blocking grille 2, so that it is fixed in the current position, thereby completing the installation operation of the blocking grille 2. At this time, the fourth electric telescopic device 44 is started, so that its output end drives the friction The rubbing square plate 45 moves to contact the inside of the guide empty box 30, thereby limiting the stop bevel block 42 to the current position, preventing the stop bevel block 42 from moving due to non-human factors when fixing the resistance grille 2, thereby improving the installation effect of the resistance grille 2; it is worth mentioning that the inclined surface of the stop bevel block 42 is facing the output end of the docking pipe 1, so that the straight surface of the stop bevel block 42 and the stop bevel groove 46 is facing the input end of the docking pipe 1. When the input end of the docking pipe 1 enters the wastewater, the pressure of the wastewater on the resistance grille 2 strengthens the straight contact strength of the stop bevel block 42 and the stop bevel groove 46, that is, the greater the pressure on the resistance grille 2, the higher the straight contact strength and friction between the stop bevel block 42 and the stop bevel groove 46, thereby preventing the resistance grille 2 from being dislocated during use, further improving the installation and use effect of the resistance grille 2, and further improving the wastewater treatment effect of the device; When it is necessary to disassemble the anti-movement grille 2, it is only necessary to release the limit setting of the stop bevel block 42. At this time, continue to push the anti-movement grille 2 from the direction of the output end of the docking pipe 1, so that the inclined surface of the stop bevel block 42 contacts the inclined surface of the stop bevel groove 46, and then continue to apply force to the stop bevel block 42 to make it move in the guide empty box 30, thereby releasing the limit setting of the anti-movement grille 2 and completing the disassembly operation of the anti-movement grille 2. The installation and disassembly operations of the anti-movement grille 2 are convenient and quick, and can be completed without the aid of any tools, thereby improving the use effect of the anti-movement grille 2, allowing the device to select and replace anti-movement grilles 2 of different specifications as needed, thereby improving the wastewater treatment effect of the device and reducing the limitations of the device during use.
