Abstract

This invention discloses an environmentally friendly wastewater treatment device for chemical distillation, relating to the field of wastewater treatment technology. It solves the problem that the elastic rubber layer fixed on the wall of the connecting ring's annular groove needs to resist the rotation of the input pipe and connecting pipe, which accelerates the wear of the elastic rubber layer and affects the sealing between the input pipe, connecting pipe, and connecting ring. The device includes a main pipe with a U-shaped pipe fixedly installed at its lower end, communicating with it. It also includes two symmetrically distributed filter structures installed inside the U-shaped pipes for filtering wastewater. This invention, through the installation of a reversing mechanism and an air-filling structure, helps prevent wastewater leakage when replacing the activated carbon filter element. By installing a positioning channel steel, positioning structure, and locking components, it effectively prevents the filter structure in the liquid flow channel from loosening. By installing the filter structure, metal baffles, and triangular baffles, it prevents a large amount of wastewater dripping when replacing the activated carbon filter box.

Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to an environmentally friendly wastewater treatment device for chemical distillation. Background Technology

[0002] Chemical wastewater refers to process wastewater, cooling water, exhaust gas scrubbing water, and equipment and site washing water discharged during chemical production. If this wastewater is discharged without treatment, it will cause varying degrees of pollution to water bodies, thereby endangering human health and affecting industrial and agricultural production. Chemical wastewater requires activated carbon filtration treatment before distillation.

[0003] Existing patent CN117023665B discloses an environmentally friendly wastewater treatment device for chemical distillation. Through the interaction of a ring and an arc-shaped extrusion strip in the trigger assembly, the cylinder rotates as the cross-shaped mounting rod drives it. When the ring and arc-shaped extrusion strip separate, the arc-shaped cover in the cylinder is open, facilitating the removal and filling of the activated carbon filter cartridge. When the ring and arc-shaped extrusion strip contact, the arc-shaped cover in the cylinder is closed, facilitating the wrapping of the placed activated carbon filter cartridge. This allows for rapid replacement of the activated carbon filter cartridge, minimizing disruption to the normal operation of the wastewater treatment process and accelerating the wastewater treatment speed.

[0004] When the activated carbon filter cartridge is replaced, the cross-shaped mounting rod drives the cylinder to rotate and disengage from the input pipe and connecting pipe. As a result, the wastewater inside the cylinder will flow out instantly, polluting the entire adsorption mechanism and the ground on which it is located. Furthermore, since the input pipe and connecting pipe are in contact with the connecting ring through an elastic rubber layer, the elastic rubber layer fixed on the wall of the annular groove of the connecting ring needs to resist the rotation of the input pipe and connecting pipe during the replacement of the activated carbon filter cartridge. This will accelerate the wear of the elastic rubber layer and affect the sealing between the input pipe, connecting pipe and connecting ring. Summary of the Invention

[0005] The purpose of this invention is to provide an environmentally friendly treatment device for chemical distillation wastewater to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An environmentally friendly wastewater treatment device for chemical distillation includes a main pipe with a U-shaped tube fixedly installed at its lower end and communicating with it.

A second spring is movably sleeved on the outer side of the pin rod, and both ends of the second spring movably abut against the semi-enclosed sleeve and the washer, respectively.

[0013] Preferably, the locking assembly includes a stop bar that can movably abut against the end of the pin away from the mounting frame.

The positioning pins slide in contact with the baffles through the strip groove.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention, through the installation of a reversing mechanism and an inflation structure, allows the valve plate in the reversing mechanism to rotate and change the flow direction of the liquid in the U-shaped tube. During the rotation of the valve plate, the inflation structure inflates the frame-shaped air bladder between the valve plate and the baffle, causing the air bladder to collide and fill the space between the valve plate and the baffle, thus providing good sealing performance between the valve plate and the baffle and helping to avoid sewage leakage when replacing the activated carbon filter element.

[0019] This invention, by installing a positioning channel steel, a positioning structure, and a locking assembly, allows the pull rope in the locking assembly to drive the stop rod in the liquid flow channel to rotate when the valve plate rotates to change the liquid flow direction. The stop rod then blocks the pin in the positioning assembly, effectively preventing the filter structure in the liquid flow channel from becoming loose.

[0020] This invention, through the installation of a filter structure, metal paddles, and triangular baffles, allows multiple metal paddles to contact multiple triangular baffles as the filter structure moves upward along with it when the filter structure is pulled out of the U-shaped tube to replace the activated carbon filter box. After bending, the multiple metal paddles spring back to their original positions, causing the activated carbon filter box to vibrate. This helps to shake off the wastewater from the activated carbon filter box and avoids a large amount of wastewater dripping when replacing the activated carbon filter box.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example

[0033] Please see Figure 1-3The diagram illustrates an environmentally friendly wastewater treatment device for chemical distillation, comprising a main pipe 1, with a U-shaped pipe 2 fixedly installed at the lower end of the main pipe 1 and communicating with it. The two ends of the U-shaped pipe 2 are connected to a distillation apparatus. The device also includes two symmetrically distributed filter structures 3 installed inside the U-shaped pipe 2 for filtering wastewater; a reversing mechanism 4 for controlling the flow direction of wastewater inside the U-shaped pipe 2, installed inside the U-shaped pipe 2 and located between the two filter structures 3; an air-inflating structure 5 for inflating the reversing mechanism 4, with two symmetrically distributed air-inflating structures 5 installed on the outside of the U-shaped pipe 2; a positioning structure 7 for positioning the filter structures 3 inside the U-shaped pipe 2, installed inside the U-shaped pipe 2 and located on the outside of the filter structures 3; and a locking assembly 8 for locking the filter structures 3 inside the U-shaped pipe 2, installed between the reversing mechanism 4 and the positioning structure 7.

[0034] Please see Figure 4 , Figure 6 The reversing mechanism 4 includes a valve plate 401 that can rotate inside the U-shaped tube 2. The lower end of the valve plate 401 is fixedly connected to a rotating shaft 402, and the rotating shaft 402 is rotatably connected to the U-shaped tube 2 through a sealed bearing. One end of the rotating shaft 402 is located outside the U-shaped tube 2 and is fixedly connected to a drive motor 403 through a coupling. The drive motor 403 can drive the rotating shaft 402 to rotate forward and backward. Two symmetrically distributed baffle frames 404 are installed on the left and right sides of the valve plate 401 inside the U-shaped tube 2, and the baffle frames 404 are fixedly connected to the U-shaped tube 2. An air bag 405 is fixedly embedded on the side of the baffle frame 404 near the valve plate 401. The connection between the valve plate 401 and the air bag 405 is a movable abutment.

[0035] Please see Figure 5 The inflatable structure 5 includes two symmetrically distributed cams 501 fixedly sleeved on the outside of the rotating shaft 402. The two cams 501 are located on the outside of the U-shaped tube 2. Two symmetrically distributed sleeves 502 are installed on the outside of the cams 501. A spline rod 503 that can move left and right is movably embedded at the end of the sleeve 502 near the cam 501. A ball bearing 504 is movably embedded at the end of the spline rod 503 near the cam 501. The ball bearing 504 is connected to the cam 501 in a rolling contact manner. The ball bearing 504 can reduce the friction between the spline rod 503 and the cam 501. A gasket 505 is fixedly connected to one end of the spline rod 503 inside the sleeve 502. A rubber sleeve 506 is fixedly sleeved on the outside of the gasket 505. The rubber sleeve 506 is movably fitted to the outer wall of the sleeve 502.

[0036] Please see Figure 5A spring 507 is movably abutted against the side of the rubber sleeve 506 away from the spline rod 503, and the end of the spring 507 away from the rubber sleeve 506 is movably abutted against the sleeve 502. A conduit 508 is fixedly embedded at the end of the sleeve 502 away from the cam 501 and communicates with it. The end of the conduit 508 away from the sleeve 502 is communicated with the airbag 405. The airbag 405 is rectangular in shape. A positioning seat 509 is fixedly sleeved on the outside of the sleeve 502. The positioning seat 509 is fixedly connected to the U-shaped tube 2 by a fixing screw.

[0037] Please see Figure 4 The filter structure 3 includes an activated carbon filter box 301. An installation frame 302 is movably sleeved on the outside of the activated carbon filter box 301, and the connection between the activated carbon filter box 301 and the installation frame 302 is a plug-in connection to facilitate the replacement of the activated carbon filter box 301. The connection between the installation frame 302 and the U-shaped tube 2 is a plug-in connection. A top plate 303 is fixedly connected to the upper end of the installation frame 302. A sealing gasket 304 is fixedly embedded on the lower end of the top plate 303 on the outside of the installation frame 302, and the connection between the sealing gasket 304 and the U-shaped tube 2 is a movable abutment. Two symmetrically distributed positioning channel steels 10 are movably sleeved on the outside of the installation frame 302, and the connection between the installation frame 302 and the positioning channel steels 10 is a plug-in connection.

[0038] Working principle: When any activated carbon filter box 301 in the U-shaped tube 2 needs to be replaced, the operator controls the drive motor 403 to run. The drive motor 403 drives the valve plate 401 to rotate towards the activated carbon filter box 301 that needs to be replaced. During the rotation of the valve plate 401, the cam 501 will rotate together. During the rotation of the cam 501, the spline rod 503 and the rubber sleeve 506 are moved through the ball bearing 504. During the movement of the rubber sleeve 506 inside the sleeve 502, the gas in the sleeve 502 is squeezed into the frame-shaped air bag 405 through the conduit 508. The air bag 405 inflates and fills the gap between the valve plate 401 and the corresponding baffle 404, so that the valve plate 401 and the baffle 404 have good sealing performance. At this time, due to the rotation of the valve plate 401, the sewage in the pipe on the side where the activated carbon filter box 301 needs to be replaced cannot flow. At this time, when the filter structure 3 is pulled out from the U-shaped tube 2, there will be no sewage leakage.

[0039] Example

[0040] Please see Figure 6 and Figure 7This embodiment further explains the first embodiment. The positioning channel steel 10 is fixedly connected to the U-shaped tube 2. The positioning structure 7 includes a semi-enclosed sleeve 701 fixedly connected to the positioning channel steel 10. A pin 702 that can move left and right passes through the interior of the semi-enclosed sleeve 701. A hemispherical part is provided at one end of the pin 702 near the mounting frame 302. A spherical groove 11 is provided on the outer side of the mounting frame 302 for the pin 702. The pin 702 is movably engaged with the mounting frame 302 through the spherical groove 11. A washer 703 is fixedly sleeved on the outer side of the pin 702. A second spring 704 is movably sleeved on the outer side of the pin 702. The two ends of the second spring 704 are respectively movably abutting against the semi-enclosed sleeve 701 and the washer 703.

[0041] When installing the filter structure 3, the hemispherical part of the pin 702 will be driven by the second spring 704 to be inserted into the spherical groove 11, which can position the filter structure 3 and make the sealing gasket 304 at the lower end of the top plate 303 fit tightly with the upper end of the U-shaped tube 2, thereby giving the filter structure 3 and the U-shaped tube 2 a good sealing performance.

[0042] Please see Figure 7 The locking assembly 8 includes a stop bar 801 that can movably abut against the end of the pin 702 away from the mounting frame 302. A positioning shaft 802 is fixedly embedded in the center of the stop bar 801. A coil spring 803 is fixedly sleeved on the outside of the positioning shaft 802. A sleeve seat 804 is sleeved on the outside of the coil spring 803. The coil spring 803 can drive the positioning shaft 802 and the stop bar 801 to rotate. The outer end of the coil spring 803 is fixedly connected to the sleeve seat 804. The sleeve seat 804 is fixedly connected to the U-shaped tube 2. A pull rope 805 is fixedly connected to the end of the stop bar 801 away from the pin 702, and the end of the pull rope 805 away from the stop bar 801 is fixedly connected to the valve plate 401.

[0043] Please see Figure 9 Two symmetrically distributed baffles 6 are installed at the upper end of the U-shaped tube 2. The baffles 6 can block the mounting groove of the filter structure 3, and the baffles 6 can move left and right at the upper end of the U-shaped tube 2. Two symmetrically distributed positioning pins 14 are movably embedded at the upper end of the baffles 6, and the positioning pins 14 are fixedly connected to the U-shaped tube 2. The positioning pins 14 slide in contact with the baffles 6 through the strip groove.

[0044] After the filter structure 3 is pulled out of the U-shaped tube 2, the baffle 6 is moved to block the mounting groove of the filter structure 3, which can effectively prevent debris from falling into the U-shaped tube 2.

[0045] In this embodiment: During the rotation of the valve plate 401, the pull rope 805 on the side of the valve plate 401 closest to the filter element to be replaced is in a relaxed state. The stop rod 801 on this side will rotate under the drive of the coil spring 803, causing the stop rod 801 to rotate and disengage from the pin 702 it is holding. At this time, when the personnel pull the filter structure 3 out of the U-shaped tube 2, the hemispherical part of the pin 702 can be easily moved out of the spherical slot 11 on the mounting frame 302, thereby facilitating the disassembly and assembly of the filter structure 3. The pull rope 805 on the side of the valve plate 401 closest to the sewage flow side is relaxed. When the rope 805 is taut and straight, the stop bar 801 on this side will rotate to a horizontal position under the pulling force of the rope 805. At this time, one end of the stop bar 801 will abut against one end of the pin 702, preventing the pin 702 from moving. Since the pin 702 cannot move, the hemispherical part of the pin 702 cannot be moved out of the spherical slot 11 on the mounting frame 302. Therefore, the filter structure 3 on this side cannot be separated from the U-shaped pipe 2, which is conducive to locking the filter structure 3. The filter structure 3 on the side where the sewage flows in the pipe becomes loose.

[0046] Example

[0047] Please see Figure 8 This embodiment further explains Example 2. Rectangular grooves are provided on both the left and right sides of the mounting frame 302. Multiple metal paddles 12 are fixedly installed in the rectangular grooves of the mounting frame 302. Multiple triangular baffles 13 are fixedly installed on the inner wall of the positioning channel steel 10. The connection between the metal paddles 12 and the triangular baffles 13 is a sliding contact. The metal paddles 12 have elastic properties.

[0048] Please see Figure 3 The upper end of the activated carbon filter box 301 is located inside the mounting frame 302 and a connecting component 9 is installed. The connecting component 9 includes a hook 901 fixedly embedded in the upper end of the activated carbon filter box 301. The outer side of the hook 901 is movably hooked to the mounting frame 302. The locking hook 902 hooks the hook 901 to prevent the activated carbon filter box 301 from detaching from the mounting frame 302. The connection between the locking hook 902 and the mounting frame 302 is a rotatable connection. Two symmetrically distributed arc springs 903 are fixedly installed on the side of the locking hook 902 away from the hook 901. The end of the arc spring 903 away from the locking hook 902 is fixedly connected to the mounting frame 302.

[0049] Please see Figure 3On the side of the locking hook 902 away from the arc spring 903, multiple equally spaced push rods 904 are movably abutted against, and the connection between the hook 901 and the push rods 904 is a movable abutment. A pressing block 905 is fixedly connected to the end of the push rod 904 away from the locking hook 902. The connection between the push rod 904 and the pressing block 905 and the mounting frame 302 is a plug-in connection. Two symmetrically distributed limiting blocks 906 are fixedly embedded on the outer side of the pressing block 905, and the limiting blocks 906 slide in contact with the mounting frame 302 through limiting grooves, preventing the pressing block 905 from detaching from the mounting frame 302.

[0050] In this embodiment: during the process of pulling the filter structure 3 out of the U-shaped tube 2, multiple triangular baffles 13 on the inner side of the positioning channel steel 10 will abut against the metal lever 12, causing the metal lever 12 to bend. When the metal lever 12 is separated from the triangular baffle 13, the metal lever 12 will rebound and reset under its own elasticity. During the upward movement, multiple metal levers 12 contact multiple triangular baffles 13, which can cause the activated carbon filter box 301 to vibrate, which is beneficial to help the activated carbon filter box 301 shake off sewage and avoid a large amount of sewage dripping when replacing the activated carbon filter box 301.

[0051] After the filter structure 3 is pulled out of the U-shaped tube 2, the operator presses the pressing block 905 on one side of the mounting frame 302. The pressing block 905 pushes the locking hook 902 to rotate through multiple push rods 904. The locking hook 902 rotates and disengages from the hook 901. At this time, the activated carbon filter box 301 can be easily pulled out from the lower end of the mounting frame 302. When installing the activated carbon filter box, the operator directly inserts the activated carbon filter box 301 into the mounting frame 302. The hook 901 can resist the inclined surface of the locking hook 902 and drive the locking hook 902 to rotate. When the hook 901 is fully inserted into the mounting frame 302, the locking hook 902 will hook the hook 901 under the drive of the arc spring 903, preventing the multiple metal paddles 12 from contacting the triangular baffle 13 and causing vibration, which would cause the activated carbon filter element 301 to vibrate and disengage from the mounting frame 302.
