Description

Technical Field

[0001] The present application relates to the technical field of water treatment, and in particular to a separation device for water treatment. Background Art

[0002] With the continuous development of social economy and the increasing level of science and technology, my country's chemical industry is also booming. Chemical wastewater, as industrial wastewater discharged from chemical production, has great harm to the environment. Therefore, it needs to be treated before it can be discharged. In the process of chemical wastewater treatment, it is often necessary to separate the chemical wastewater into solid and liquid.

[0003] Regarding the above-mentioned related technologies, since a filter net is usually used in the prior art, chemical wastewater is passed through the top of the filter net to filter the solid impurities in the chemical wastewater, thereby achieving solid-liquid separation of the chemical wastewater. However, during the filtration process, the solid impurities in the chemical wastewater will continue to accumulate on the surface of the filter net, thereby increasing the probability of the filter net being blocked, and further resulting in a decrease in the solid-liquid separation efficiency, so there is room for improvement. Summary of the invention

[0004] In order to reduce the probability of the filter being blocked by solid impurities, the present application provides a separation device for water treatment.

[0005] The present application provides a separation device for water treatment, which adopts the following technical solution: A separation device for water treatment comprises a device body, on which a water inlet pipe and a water outlet pipe are arranged, a mounting frame is arranged inside the device body, a filter cover is arranged on the outer side of the mounting frame, the mounting frame is located inside the filter cover and connected to the filter cover, one end of the water inlet pipe connected to the device body is lower than the filter cover, and a chamber between the mounting frame and the filter cover is connected to the water outlet pipe.

[0006] By adopting the above technical scheme, compared with the prior art in which chemical sewage is passed from the top of the filter screen, the solid impurities in the chemical sewage are continuously retained on the filter screen, which can easily cause the filter screen to be blocked, thereby reducing the solid-liquid separation efficiency; the present application arranges the mounting frame and the filter cover so that the chemical sewage passed through the water inlet pipe can be passed from the bottom of the filter cover to the chamber of the equipment body, thereby reducing the probability of solid impurities in the chemical sewage being retained above the filter cover for a long time, thereby reducing the probability of the top of the filter cover being blocked; at the same time, the bottom end of the filter cover can be located in the liquid surface in the equipment body, so that the filter cover filters the chemical sewage above the liquid surface, and the solid impurities in the chemical sewage in the filtering process automatically settle to the bottom of the equipment body chamber under their own gravity, thereby reducing the probability of the lower part of the filter cover being blocked, and effectively reducing the probability of reduced solid-liquid separation efficiency due to the blockage of the filter cover.

[0007] Preferably, the top end of the equipment body is opened, the bottom of the inner chamber of the equipment body is arc-shaped, the mounting frame is rotatably connected to the equipment body, and the rotation axis is coaxially arranged with the bottom of the inner chamber of the equipment body, the equipment body is also provided with a rotating member, the rotating member is used to drive the mounting frame to rotate, the mounting frame is provided with an impurity handling mechanism, the impurity handling mechanism includes a plurality of extension frames, the plurality of extension frames are arranged on the outside of the mounting frame, each of the extension frames is against the inner wall of the bottom of the inner chamber of the equipment body, and each of the extension frames is provided with a filter.

[0008] By adopting the above technical solution, the impurity handling mechanism is set up so that when the mounting frame is driven by the rotating member to rotate, it can drive each extension frame to rotate at the same time, and the filter net on the extension frame can drive the solid impurities at the bottom of the chamber in the equipment body during the rotation, and make the solid impurities gradually adhere to the filter net, so that the solid impurities can be fished out of the equipment body by the filter net, and finally thrown to the outside of the equipment body, thereby reducing the number of solid impurities in the chamber of the equipment body, increasing the efficiency of solid-liquid separation, and at the same time can further reduce the probability of the filter cover being blocked.

[0009] Preferably, each of the filter screens is rotatably connected to the corresponding extension frame, and the impurity handling mechanism further comprises a plurality of driving components, the driving components correspond one to one with the filter screens, and the mounting frame drives the corresponding filter screens to rotate through the driving components.

[0010] By adopting the above technical solution and setting the driving component, when the mounting frame is rotating, when the extension frame has just rotated out of the device body, the mounting frame can drive the filter screen on the extension frame to rotate through the driving component, so that one end of the filter screen tilts downward, and then the solid impurities on the filter screen can roll to the outside of the device body along the tilt direction of the filter screen, thereby realizing automatic cleaning of the solid impurities on the filter screen and reducing the amount of solid impurities in the chamber of the device body.

[0011] Preferably, the impurity handling mechanism also includes a driving member, each of the driving components includes a sliding frame and a supporting frame, each of the sliding frames is slidably connected to the corresponding extension frame, each of the sliding frames is rotatably connected to one end of the corresponding filter screen close to the filter cover, one end of each of the supporting frames is rotatably connected to the corresponding extension frame, and the other end is rotatably connected to the corresponding filter screen, and the mounting frame drives each of the sliding frames to slide through the driving member.

[0012] By adopting the above technical scheme and the specific setting of the driving component, during the rotation of the mounting frame, when the extension frame has just rotated out of the equipment body, the driving member can drive the sliding frame on the extension frame to slide, so that the sliding frame drives one end of the filter screen to slide, and the filter screen can drive the support frame to displace during the sliding process, and then the filter screen rotates with the displacement of the support frame, thereby effectively realizing the displacement and rotation of the filter screen, so that the filter screen moves away from one end of the filter cover and outside the extension frame, thereby ensuring that the solid impurities that roll off fall outside the equipment body, reducing the probability of the solid impurities falling back into the opening of the equipment body.

[0013] Preferably, each of the filter screens is provided with a cleaning assembly, each of the cleaning assembly comprises a cleaning frame and a linkage, each of the cleaning frames is slidably connected to the corresponding filter screen, and the sliding direction is the direction of the corresponding filter screen after tilting, and each of the linkages is used to drive the corresponding cleaning frame to slide.

[0014] By adopting the above technical solution, the cleaning component is set up so that during the process of the filter screen tilting, the linkage can drive the cleaning frame to slide toward the downward tilted end of the filter screen, so that the cleaning frame can push the solid impurities on the filter screen to the downward tilted side of the filter screen through its own sliding, thereby reducing the number of solid impurities retained on the filter screen after the filter screen tilts, thereby improving the efficiency of solid-liquid separation of chemical wastewater.

[0015] Preferably, the linkage member comprises a linkage frame, one end of the linkage frame is rotatably connected to the corresponding cleaning frame, and the other end of the linkage frame is slidably connected to the corresponding supporting frame.

[0016] By adopting the above technical solution, the linkage frame is set up so that when the filter screen is tilted and the support frame rotates, the support frame can drive the linkage frame to rotate together, so that the intersection of the straight line in the length direction of the linkage frame itself and the filter screen changes, and then the cleaning frame slides relative to the filter screen, so that when the filter screen rotates, the cleaning frame can automatically slide, thereby realizing the linkage between the support frame and the cleaning frame, thereby saving the active components required to drive the cleaning frame and saving the setting cost of the present application.

[0017] Preferably, the driving member includes a driving cam, which is connected to the equipment body and coaxially arranged with the mounting frame. The side wall of the driving cam abuts against one end of each sliding frame close to the filter cover.

[0018] By adopting the above technical solution and setting the driving cam, when the extension frame rotates with the mounting frame, when the extension frame is displaced outside the opening of the equipment body, the sliding frame on the extension frame abuts against the protruding part of the driving cam, thereby causing the sliding frame to slide, thereby driving the sliding frame to slide, so that the sliding frame can automatically slide when it rotates to a specified position with the mounting frame, thereby facilitating the smooth driving of the sliding frame.

[0019] Preferably, a return spring is provided on each of the extension frames, and the return spring is located on a side of the corresponding sliding frame away from the filter cover, one end of the return spring abuts against the corresponding sliding frame, and the other end abuts against the corresponding extension frame.

[0020] By adopting the above technical solution and setting the return spring, the sliding frame slides under the drive of the driving cam, and in the process of sliding to the end of the sliding path, the return spring is compressed, thereby storing elastic potential energy, so that when the sliding frame gradually moves away from the driving cam, the sliding frame can be driven by the return spring to gradually return to the initial position and continue to abut against the outer wall of the driving cam, so that the filter can automatically return to the initial position driven by the sliding frame, thereby ensuring the normal use of the filter net in the future and ensuring the smooth operation of the present application.

[0021] Preferably, one end of each of the support frames rotatably connected to the corresponding extension frame is inclined away from the end of the corresponding filter screen.

[0022] By adopting the above technical solution, the positions of the two ends of the support frame are set so that when the sliding frame does not slide, the sliding direction of the sliding frame is not parallel to the connection direction of the connection between the two ends of the support frame, thereby eliminating the dead point position on the connecting frame, reducing the probability of mutual obstruction between the sliding frame and the support frame, and then the sliding frame can smoothly drive the filter net to move, ensuring the smooth operation of the present application.

[0023] Preferably, a guide surface is provided at the top of the end of the equipment body away from the water inlet pipe, and the guide surface is inclined downward away from the end of the water inlet pipe.

[0024] By adopting the above technical solution and setting the guide surface, the solid impurities falling through the filter net can roll downward along the inclined direction of the guide surface after falling onto the guide surface, and finally fall outside the equipment body, thereby effectively reducing the probability of the solid impurities remaining on the equipment body after falling, and at the same time making it convenient for relevant personnel to collect the separated solid impurities.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The installation frame and the filter cover are arranged so that the chemical sewage introduced by the water inlet pipe can be introduced into the chamber of the equipment body from the bottom of the filter cover, thereby reducing the probability of solid impurities in the chemical sewage being retained above the filter cover for a long time, thereby reducing the probability of the filter cover being blocked. At the same time, the bottom end of the filter cover can be located within the liquid surface in the equipment body, so that the filter cover can filter the chemical sewage above the liquid surface, and the solid impurities in the chemical sewage can automatically settle to the bottom of the chamber of the equipment body under their own gravity during the filtering process, thereby reducing the probability of the lower part of the filter cover being blocked, and effectively reducing the probability of the solid-liquid separation efficiency being reduced due to the filter cover being blocked; 2. The impurity treatment mechanism is set so that when the mounting frame is driven by the rotating member to rotate, each extension frame can be driven to rotate at the same time, and the filter screen on the extension frame can drive the solid impurities at the bottom of the chamber in the equipment body during the rotation process, and make the solid impurities gradually adhere to the filter screen, so that the solid impurities can be fished out of the equipment body by the filter screen, and finally thrown to the outside of the equipment body, thereby reducing the number of solid impurities in the chamber of the equipment body, increasing the efficiency of solid-liquid separation, and further reducing the probability of the filter cover being blocked; 3. The drive assembly is arranged so that when the mounting frame is rotating, when there is an extension frame just rotating out of the equipment body, the mounting frame can drive the filter screen on the extension frame to rotate through the drive assembly, so that one end of the filter screen tilts downward, and then the solid impurities on the filter screen can roll to the outside of the equipment body along the tilt direction of the filter screen, thereby realizing automatic cleaning of the solid impurities on the filter screen and reducing the amount of solid impurities in the chamber of the equipment body.

[0035] Reference Figure 1 and Figure 3 The top opening of the device body 1 is arranged so that the chamber in the device body 1 is connected with the outside. The bottom of the chamber in the device body 1 is in an arc shape. In the embodiment of the present application, the chamber is in a semicircular shape.

[0036] Reference Figure 2 and Figure 3 The filter cover 21 is located outside the mounting frame 2 and is coaxially arranged with the mounting frame 2. Both ends of the mounting frame 2 along its own axial direction extend outside the filter cover 21 and are fixedly connected to the filter cover 21. The lower part of the filter cover 21 is located below the liquid level in the equipment body 1 to filter the chemical wastewater.

[0037] Reference Figure 1 Both ends of the mounting frame 2 are rotatably connected to the device body 1 through bearings, and the rotation axis is the axis of the mounting frame 2. The device body 1 is also provided with a rotating member 4. In the embodiment of the present application, the rotating member 4 is configured as a reduction motor, which is fixedly mounted on the side wall of the device body 1, and the output shaft is fixedly connected to one end of the mounting frame 2 through a coupling to realize the driving of the mounting frame 2 to rotate.

[0038] Reference Figure 1 and Figure 2 A connecting pipe 22 is also provided on the side of the mounting frame 2 away from the rotating member 4. The connecting pipe 22 is fixedly connected to the mounting frame 2 and communicates with the chamber between the mounting frame 2 and the filter cover 21. An intermediate clamp 5 is also provided on the connecting pipe 22. The intermediate clamp 5 is located above the connecting pipe 22 and is fixedly connected to the device body 1 through a plurality of bolts. The intermediate clamp 5 is sleeved on the connecting pipe 22 to restrict the connecting pipe 22 by clamping.

[0039] Reference Figure 1 , the middle hoop 5 and the equipment body 1 are rotatably connected to the mounting frame 2 through a bearing. In the embodiment of the present application, a sealing ring may be further provided between the middle hoop 5 and the equipment body 1 to seal between the middle hoop 5 and the equipment body 1. One end of the outlet pipe 12 is located between the middle hoop 5 and the equipment body 1, so that the middle hoop 5 and the equipment body 1 are sleeved on the outlet pipe 12, and the outlet pipe 12 is connected with the connecting pipe 22, so as to realize the discharge of the chemical wastewater between the filter cover 21 and the mounting frame 2.

[0040] Reference Figure 1 Hehe Figure 4 The top of the end of the equipment body 1 away from the water inlet pipe 11 is also provided with a guide surface, which is away from the end of the water inlet pipe 11 and is inclined downward. The mounting frame 2 is also provided with an impurity handling mechanism 6, which includes a driving member 61, a plurality of extension frames 62 and a plurality of driving components 63. The plurality of extension frames 62 are arranged at equal angles along the circumference of the axis of the mounting frame 2. The axis of the mounting frame 2 intersects with a straight line in the width direction of each extension frame 62. One end of each extension frame 62 along its width direction is fixedly connected to the outer side wall of the mounting frame 2, and the other end is against the inner side wall of the arc shape in the equipment body 1.

[0041] Reference Figure 1 and Figure 4, driving members 61 are provided at both ends of the mounting frame 2 extending out of the filter cover 21, and each driving member 61 includes a driving cam 611. Each driving cam 611 is fixedly connected to the inner side wall of the device body 1, and is sleeved on the corresponding end of the mounting frame 2, and is rotatably connected to the mounting frame 2 through a bearing. The protruding end of each driving cam 611 extends toward an end away from the water inlet pipe 11, and is tilted upward.

[0042] Reference Figure 1 and Figure 4 Each extension frame 62 is frame-shaped, and each extension frame 62 is provided with two driving components 63, which are respectively located at both sides of the extension frame 62 along its width direction, and each driving component 63 includes a sliding frame 631 and a supporting frame 632. The two sliding frames 631 on each extension frame 62 are respectively located at both ends of the extension frame 62 along its length direction, and both pass through the side wall of the extension frame 62 to reach the extension frame 62, and are slidably connected with the corresponding extension frame 62, and the sliding direction is the width direction of the extension frame 62. One end of each sliding frame 631 close to the mounting frame 2 is set to be arc-shaped, and this end is against the side wall of the driving cam 611.

[0043] Reference Figure 1 and Figure 4 A return spring 7 is sleeved on one end of each sliding frame 631 away from the driving cam 611, and one end of each return spring 7 abuts against the end of the corresponding sliding frame 631 away from the driving cam 611, and the other end of each return spring 7 abuts against the outer wall of the extension frame 62, so that when the driving cam 611 abuts and causes the sliding frame 631 to slide, the return spring 7 can be compressed, thereby storing elastic potential energy, so that in the subsequent process, the return spring 7 can drive the sliding frame 631 to slide back through its own elastic force, so that the sliding frame 631 continues to abut against the side wall of the driving cam 611.

[0044] Reference Figure 1 and Figure 4 A filter screen 64 is also arranged between the two sliding frames 631 on each extension frame 62. Each filter screen 64 includes a body portion 641 and a frame portion 642. The frame portion 642 is sleeved on the body portion 641 and fixedly connected to the body portion 641. The meshes on the filter screen 64 are all opened on the body portion 641. One end of each frame portion 642 is rotatably connected to the corresponding two sliding frames 631 through a pin shaft.

[0045] Reference Figure 1 and Figure 4One end of each support frame 632 is rotatably connected to the corresponding frame portion 642 away from the mounting frame 2 through a pin, and the other end of each support frame 632 is rotatably connected to the top of the extension frame 62 through a pin. Each support frame 632 is tilted with the corresponding frame portion 642, and one end of each support frame 632 rotatably connected to the extension frame 62 is tilted in a direction away from the frame portion 642 to ensure the smooth operation of the present application.

[0046] Reference Figure 1 and Figure 4 In the initial state, the end of the sliding frame 631 that is in contact with the driving cam 611 is not in contact with the protrusion on the driving cam 611. At this time, the filter screen 64 and the extension frame 62 remain parallel and do not rotate. When the extension frame 62 rotates with the mounting frame 2 and rotates to the side away from the water inlet pipe 11, the sliding frame 631 gradually contacts the protrusion on the driving cam 611, so that the sliding frame 631 gradually slides in the direction away from the mounting frame 2.

[0047] Reference Figure 1 and Figure 4 During this process, the sliding frame 631 drives the filter screen 64 close to the end of the mounting frame 2 and slides together in the direction away from the mounting frame 2. At this time, the support frame 632 moves accordingly and adjusts its own inclination angle to support the filter screen 64, so that the filter screen 64 away from the end of the mounting frame 2 gradually tilts downward, thereby dumping the solid impurities accumulated on the filter screen 64 and falling onto the guide surface at the end of the equipment body 1, rolling along the inclination direction of the guide surface, and finally falling outside the equipment body 1.

[0048] Reference Figure 1 and Figure 4 A cleaning assembly 65 is provided on each filter screen 64, and each cleaning assembly 65 includes a cleaning frame 651 and a linkage member 652. One end of each cleaning frame 651 is embedded in the outer wall of the corresponding frame portion 642 near the corresponding support frame 632 and the corresponding extension frame 62, and is slidably connected to the corresponding frame portion 642, and the sliding direction is the width direction of the corresponding frame portion 642.

[0049] Reference Figure 4Each linkage member 652 includes a linkage frame 6521, and the number of linkage frames 6521 on each cleaning frame 651 is set to two, and the two linkage frames 6521 are respectively located at the two ends of the corresponding cleaning frame 651 along its own length direction. One end of each linkage frame 6521 is rotatably connected to the corresponding cleaning frame 651 through a pin, and the other end of each linkage frame 6521 passes through an end of the corresponding support frame 632 away from the filter screen 64, and is slidably connected to the inner wall of the corresponding support frame 632. The length direction of each linkage frame 6521 is offset from the length direction of the corresponding support frame 632, and each linkage frame 6521 is tilted toward the side of the corresponding support frame 632 close to the mounting frame 2.

[0050] Reference Figure 1 and Figure 4 In the initial state, that is, when the filter screen 64 is not tilted with the corresponding extension frame 62, the cleaning frame 651 is located at the end of the filter screen 64 close to the mounting frame 2. When the extension frame 62 rotates together with the mounting frame 2 and rotates to the side away from the water inlet pipe 11, the driving cam 611 pushes the sliding frame 631 to slide, and the supporting frame 632 drives the linkage frame 6521 to rotate relative to the filter screen 64.

[0051] Reference Figure 1 and Figure 4 At this time, the intersection point of the straight line in the length direction of the linkage frame 6521 and the filter screen 64 changes, so that the linkage frame 6521 drives the cleaning frame 651 to slide in the direction close to the support frame 632, and then the cleaning frame 651 pushes the solid impurities at one end of the filter screen 64 close to the mounting frame 2 to the other end, thereby reducing the probability of solid impurities remaining in the filter screen 64 close to the mounting frame 2.

[0052] The implementation principle of a separation device for water treatment in the embodiment of the present application is as follows: when the driving member 61 drives the filter cover 21 to rotate, the extension frame 62 rotates together with the mounting frame 2. When one of the extension frames 62 rotates to the side away from the water inlet pipe 11, the sliding frame 631 gradually abuts against the protrusion on the driving cam 611, so that the sliding frame 631 gradually slides in the direction away from the mounting frame 2, and the filter screen 64 is close to one end of the mounting frame 2, and slides in the direction away from the mounting frame 2 together. At this time, the support frame 632 is displaced accordingly, so that the filter screen 64 is away from one end of the mounting frame 2 and gradually tilts downward.

[0053] During this process, the support frame 632 drives the linkage frame 6521 to rotate relative to the filter screen 64, so that the linkage frame 6521 drives the cleaning frame 651 to slide in the direction close to the support frame 632, and then the cleaning frame 651 pushes the solid impurities on one end of the filter screen 64 close to the mounting frame 2 to the other end. During this process, the solid impurities on the filter screen 64 fall onto the guide surface at the end of the equipment body 1 along the inclined direction of the guide surface.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
