Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment, specifically a wastewater treatment device for metalworking fluid production. Background Technology

[0002] Metalworking fluid production processes easily generate large amounts of wastewater. To protect the environment, wastewater treatment is necessary. The general steps involved in wastewater treatment are: wastewater filtration → sedimentation of small particulate impurities → sterilization. In the treatment of small particulate impurities, flocculation sedimentation is typically used. This involves passing wastewater into a sedimentation tank, adding flocculants, and then stirring the wastewater and flocculants to increase the contact rate between small particulate impurities and the flocculants. After contact, flocs form and then settle. However, this method still has the following drawbacks: During flocculation, the presence of light impurities in the wastewater results in light flocs that settle slowly, leading to long flocculation times and low sedimentation efficiency.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by intermittently switching the electromagnet on and off, can drive the stirring plate to swing up and down, and in conjunction with the rotation of the treatment block, improve the stirring effect on wastewater and enhance the contact effect between small particle sediments and flocculants. When the electromagnet is continuously energized, the stirring plate is kept horizontal and magnetized, which facilitates the adsorption of flocs containing magnetically attracted metal particles and composite flocs formed by the combination of magnetic activated carbon and non-magnetic particles, thereby improving the sedimentation treatment efficiency. 2. In this invention, when the electromagnet is intermittently switched on and off, it can drive the stirring plate to swing up and down and at the same time drive the piston plate to move laterally along the horizontal feed pipe, thereby continuously pushing the flocculant mixture and the magnetic activated carbon mixture into the wastewater, which facilitates the flocculant and magnetic activated carbon to flocculate and agglomerate with small particulate impurities at different positions in the wastewater. 3. In this invention, a sliding plate is provided inside the rotating circular plate. When stirring, the sliding plate is located inside the rotating circular plate and does not contact the magnetic base. The distance between the sliding plate and the magnetic base is far, so that the stirring plate cannot be magnetized, thus avoiding the adsorption of magnetic activated carbon entering the wastewater during stirring. When adsorbing flocs, the rotating circular plate is rotated and inverted, causing the sliding plate to move outward and contact the magnetic base, which facilitates the magnetization of the stirring plate and facilitates the adsorption of flocs. 4. In this invention, by continuously energizing an electromagnet, the gas below the piston block expands and pushes the rack upward. On the one hand, this causes the rotating circular plate to rotate, magnetizing the stirring plate. On the other hand, it can drive the annular plate to engage the arc-shaped locking rod in the arc-shaped locking groove, fixing the stirring plate and maintaining the magnetization stability of the stirring plate. 5. In this invention, by continuously energizing an electromagnet, the stirring plate is kept horizontal and magnetized, which facilitates the attraction and attachment of flocs containing magnetically attracted metal particles and composite flocs formed by the combination of magnetic activated carbon and non-magnetic particles to the stirring plate. When the electromagnet is de-energized, the stirring plate rotates, tilts and demagnetizes, allowing the flocs to slide off and be discharged, which facilitates the processing of the flocs. 6. In this invention, a heat-conducting rod is installed on the fixed box, with one end of the heat-conducting rod penetrating into the wastewater. When the electromagnet is intermittently energized and de-energized, the heat-conducting rod can carry heat into the wastewater, and since the electromagnet itself is energized for a short time, the temperature on the fixed box is stable, ensuring that the stirring plate will not be magnetized during stirring.

When the electromagnet 20715 is continuously energized, the stirring plate 2075 is kept horizontal and magnetized, which facilitates the adsorption of flocs containing magnetically attracted metal particles and composite flocs formed by the combination of magnetic activated carbon and non-magnetic particles, thereby improving the sedimentation treatment efficiency. The bottom of the movable block 2079 is provided with an additive extruder 208, and the top of the treatment block 2071 is provided with a magnetized fixing part 209.

[0020] The extruder 208 includes a lower movable cavity 2081 located inside the processing block 2071, below the upper movable cavity 2078.

The feed pipe 2088 is located at the end of the horizontal material pipe 2083 away from the treatment block 2071 and on the side of the first check valve 2087 close to the treatment block 2071. A second check valve 2089 is installed inside the feed pipe 2088. When the electromagnet 20715 is intermittently energized and de-energized, it can drive the stirring plate 2075 to swing up and down and at the same time drive the piston plate 2084 to move laterally along the horizontal material pipe 2083, thereby continuously pushing the flocculant mixture and the magnetic activated carbon mixture into the wastewater, which facilitates the flocculant and magnetic activated carbon to flocculate and form agglomerates with small particulate impurities at different positions in the wastewater.

[0021] Two storage bins 20810 are installed on the front of the processing block 2071. The height of the storage bins 20810 is higher than the height of the bottom rod 2082.

A ball valve 20813 is installed on the filling pipe 20812. The two bottom pipes 20811 are connected to two feed pipes 2088 through connecting hoses. The two storage bins 20810 store flocculant mixture and magnetic activated carbon mixture, respectively.

[0022] The magnetization fixing component 209 includes an annular groove 2091 formed inside the top plate of the processing block 2071. An annular plate 2092 is rotatably installed inside the annular groove 2091. First toothed plates 2093 are evenly installed on the bottom wall of the annular plate 2092.

A circular cavity is disposed inside the bottom circular plate 20915, and a circumferential groove 20916 is formed on the outer side of the circular cavity. A rotating circular plate 20917 is mounted inside the cavity. An electromagnet 20715 is continuously energized, causing the rotating circular plate 20917 to rotate and magnetize the stirring plate 2075. Simultaneously, it drives the annular plate 2092 to engage the arc-shaped locking rod 2096 into the arc-shaped locking groove 2097, thus fixing the stirring plate 2075 and maintaining its magnetization stability. A sliding groove 20918 is formed inside the rotating circular plate 20917, with its top end extending to the top of the rotating circular plate 20917. The interior of the sliding groove 20918 is movable. A sliding plate 20919 is installed inside the rotating circular plate 20917. During stirring, the sliding plate 20919 is located inside the rotating circular plate 20917 and does not contact the magnetic base 20716. The distance between the sliding plate 20919 and the magnetic base 20716 is relatively large, preventing the stirring plate 2075 from being magnetized and avoiding the adsorption of magnetic activated carbon entering the wastewater during stirring. When adsorbing flocs, the rotating circular plate 20917 rotates and inverts, causing the sliding plate 20919 to move outward and contact the magnetic base 20716, facilitating stirring. The mixing plate 2075 is magnetized to facilitate the adsorption of flocs. An upper rotating shaft 20910 is coaxially mounted on the circular plate 2098. The upper rotating shaft 20910 is rotatably connected to the hanging plate 20914. A lower rotating shaft 20911 is provided below the upper rotating shaft 20910. One end of the lower rotating shaft 20911 is coaxially connected to the rotating circular plate 20917.

[0024] The temperature drive component 210 includes a gear 2101 fixedly mounted on the lower rotating shaft 20911. A rack 2102 is meshed with one side of the gear 2101. A fixed housing 2103 is provided on the side of the rack 2102 away from the gear 2101. The fixed housing 2103 is fixedly mounted on the magnetic base 20716. A piston block 2104 is movably mounted inside the fixed housing 2103. A second spring 2106 is mounted at the bottom end of the piston block 2104. The bottom end of the second spring 2106 is fixedly connected to the inner bottom wall of the fixed housing 2103. A connecting rod 2 is mounted at the top end of the piston block 2104. 105. The connecting rod 2105 is fixedly connected to the rack 2102. A heat-conducting rod 2107 is installed on one side of the fixed box 2103. One end of the heat-conducting rod 2107 extends to the outside of the processing block 2071. The fixed box 2103 is equipped with a heat-conducting rod 2107. One end of the heat-conducting rod 2107 extends into the wastewater. When the electromagnet 20715 is intermittently energized and de-energized, the heat-conducting rod 2107 can carry heat into the wastewater. Since the electromagnet 20715 itself is energized for a short time, the temperature on the fixed box 2103 is stable, ensuring that the stirring plate 2075 will not be magnetized during stirring.

[0025] Working principle: When in use, the wastewater from the metalworking fluid production is introduced into the filter tank 3. The filter tank 3 is equipped with a filter screen, which filters out large particulate impurities in the wastewater, thus forming the first stage of wastewater treatment. Then, the water pump 502 and the plate gate valve 503 between the sedimentation tank 1 and the filter tank 3 are turned on to allow the filtered wastewater to flow into the sedimentation tank 1. Then, the plate gate valve 503 is turned off. Before the wastewater flows into the sedimentation tank 1, the flocculant mixture and the magnetic activated carbon mixture need to be stored in the two storage tanks 20810 on the treatment block 2071, respectively. After the wastewater flows into the sedimentation tank 1, the drive motor 206 is turned on to drive the rotating shaft 205 to rotate, thereby driving the treatment block 2071 to rotate. At the same time, the longitudinal drive module 203 drives the mounting platform 204 to move longitudinally back and forth, thereby driving the treatment block 2071 to move back and forth. Then, the electromagnet 20715 is intermittently switched on and off. When the electromagnet 20715 is energized, it attracts the magnetic block 20714, causing the vertical rod 20710 to move downwards. This, in turn, drives the hanging plates 20712 downwards via the horizontal rod 20711. Since the bottom end of the hanging plate 20712 is hinged to the rotating plate 2074, it pulls the rotating plate 2074 to rotate via the rotating head 2077 and the rotating side seat 2073. When the electromagnet 20715 is de-energized, the movable block 2079 is released by the elastic force of the first spring 20713. Under the action of the action, it moves upward and back, thereby pulling the rotating plate 2074 to rotate through the vertical rod 20710, horizontal rod 20711 and hanging plate 20712, thereby driving the stirring plate 2075 to swing longitudinally back and forth to stir the wastewater. The surface of the stirring plate 2075 is equidistantly provided with protruding plates 2076, which are arranged along the length of the stirring plate 2075. During the rotation of the treatment block 2071, the protruding plates 2076 can stir the wastewater, which facilitates the mixing and flocculation of flocculant with small particulate impurities in the wastewater, and facilitates the formation of flocs. Simultaneously, during the longitudinal reciprocating movement of the movable block 2079, when the movable block 2079 moves downward, the connecting rod 2086 pulls the piston plate 2084 towards the lower movable chamber 2081. At this time, the flocculant mixture and magnetic activated carbon mixture in the storage tank 20810 enter the two horizontal feed pipes 2083 under the action of gravity. The second one-way valve 2089 allows external media to enter the horizontal feed pipe 2083, but does not allow the media in the horizontal feed pipe 2083 to be discharged from the feed pipe 2088. When the movable block 2079 moves upward, the connecting rod 2086 pushes the piston plate 2084 towards the side away from the lower movable chamber 2081, thereby pushing the flocculant mixture and magnetic activated carbon mixture in the horizontal feed pipe 2083 into the wastewater. The first one-way valve 2087 allows the media in the horizontal feed pipe 2083 to be discharged, but does not allow external media to enter the horizontal feed pipe 2083. After the flocculant mixture and the magnetic activated carbon mixture enter the wastewater, the flocculant continuously combines with small particulate impurities in the wastewater to form flocs, which then precipitate. Some of these flocs contain metal particles that can be attracted by magnets. After the addition of magnetic activated carbon, non-magnetic precipitated particles will adhere to the surface of the magnetic activated carbon through "physical adsorption and chemical bonding", forming composite flocs formed by the combination of magnetic activated carbon and non-magnetic particles. After mixing and forming a large number of flocs, the intermittent switching of the electromagnet 20715 is stopped, and the electromagnet 20715 is continuously energized, causing the movable block 2079 to move to its lowest limit position. At this time, the stirring plate 2075 remains horizontal. Meanwhile, as the electromagnet 20715 is continuously energized, it accumulates heat. Since the electromagnet 20715 is mounted on the magnetic base 20716, the heat is transferred to the interior of the fixed box 2103, causing the gas in the space below the piston block 2104 to expand due to the heat. This pushes the rack 2102 to move upward. The rack 2102 meshes with the gear 2101, thereby driving the lower rotating shaft 20911 to rotate. This, in turn, drives the circular plate 2098 to rotate through the transmission belt 20913 and the pulley 20912. When the rack 2102 moves upward to its limit position, the lower rotating shaft 20911 rotates 180 degrees, causing the rotating circular plate 20917 to invert. This causes the sliding plate 20919 to slide downward under its own weight, bringing its end into contact with the magnetic base 20716. The magnetic base 20716, the bottom circular plate 20915, the rotating circular plate 20917, the sliding plate 20919, the hanging plate 20914, the top plate of the processing block 2071, as well as the rotating plate 2074 and the stirring plate 2075 are all supported by magnetic materials. When the sliding plate 20919... After the end contacts the magnetic seat 20716, the stirring plate 2075 generates a magnetic force, which can adsorb flocs containing magnetically attracted metal particles and composite flocs formed by the combination of magnetic activated carbon and non-magnetic particles, solving the problem of "light flocs and slow settling", thereby improving the treatment speed of small particulate impurities in wastewater and improving wastewater treatment efficiency. When the electromagnet 20715 is intermittently energized and de-energized, due to the short energization time, the heat-conducting rod 2107 will transfer the generated heat to the wastewater, and heat accumulation will not occur, thus preventing the rack 2102 from moving. At the same time, the circular plate 2098 rotates, which drives the annular plate 2092 to rotate through the second toothed plate 2099 and the first toothed plate 2093. This allows the arc-shaped locking rod 2096 on the top block 2095 to be engaged in the arc-shaped locking groove 2097 on the rotating plate 2074, thus fixing the top groove 2094 and ensuring the tight fit between the top groove 2094 and the top plate of the processing block 2071. This also ensures the magnetization stability of the top block 2095, thereby improving the adsorption stability of the flocs. After adsorption is complete, the top cover 201 is pulled up, causing the processing block 2071 to leave the sedimentation tank 1. A sedimentation storage basin is placed below the top cover 201. Then, the electromagnet 20715 is de-energized. After a certain period of de-energization, the temperature of the electromagnet 20715 and the fixed box 2103 drops, causing the gas below the piston block 2104 to contract back to its original state. This causes the rack 2102 to move back, which in turn drives the rotating circular plate 20917 to rotate. When the rotating circular plate 20917 rotates to the point where the end of the sliding plate 20919 tilts upward, the sliding plate... Under the action of gravity, the moving plate 20919 automatically retracts into the sliding groove 20918, and at the same time drives the annular plate 2092 to rotate, causing the arc-shaped locking rod 2096 to disengage from the rotating plate 2074. This causes the moving block 2079 to move upward under the elastic force of the first spring 20713, causing the end of the stirring plate 2075 to tilt downward. At the same time, due to the disappearance of the magnetic force, the stirring plate 2075 is demagnetized. At this time, the flocs that are attached to the surface of the stirring plate 2075 by the magnetic attraction fall into the sedimentation storage basin under the action of gravity, and the flocs are collected. Then, the water pump 502 between sedimentation tank 1 and sterilization tank 4 is turned on to introduce wastewater into sterilization tank 4 and add bactericide to sterilize the wastewater. At the same time, the sediment in sedimentation tank 1 is treated.
